Cable Conveyor Operation and Maintenance

(1) During the initial operation period of the cable conveyor, pay close attention to checking the tightness of the scraper chain, as the spacing between the troughs may decrease due to operation. If the chain is too loose, it could lead to chain jamming, chain skipping, chain breakage, or even chain derailment. To check the tension, reverse the conveyor and count the number of slack chain links. If there are two or more completely slack links, the chain needs to be tightened again. (2) The working face must remain straight. If the working face is not straight, the tension on the two chains will become unequal, resulting in uneven chain wear or causing the bottom chain to derail, get stuck, or break. (3) The conveyor’s curvature should be moderate; avoid sharp bends. The curved section should be no less than eight trough sections. When moving the conveyor, ensure that the front and rear hydraulic jacks work in coordination to prevent sharp bends. Otherwise, this could cause misalignment of the troughs, leading to chain breakage or derailment. Be especially careful not to move the conveyor when it is stopped. (4) The conveyor must be laid out smoothly. Due to the structural characteristics of the troughs, they can only accommodate vertical variations of 3–5 feet. Therefore, if the working face floor has local irregularities, these should be leveled. Moreover, a smoothly laid-out conveyor facilitates smoother operation of the scraper chain, reduces trough wear, and lowers power consumption. (5) During blasting operations, be sure to protect the conveyor’s drive components, pipelines, unit cables, switches, and other equipment carefully. When the conveyor transports iron materials or long objects, safety measures must be established to prevent personal accidents. (6) At the joints between the transition trough and the tail section as well as between the middle troughs, avoid excessive bending. If there is any bending, use wooden boards to provide support. (7) Pay close attention to the vibration of the coupling. While the conveyor is running, monitor the vibration of the hydraulic coupling. To ensure good heat dissipation, regularly clean the protective cover plates and the hydraulic fluid.

The internal structure of the cable conveyor

What is a cable conveyor? It is a mechanical device used for transporting cables, comprising a main frame, a conveying mechanism consisting of a motor, a speed-reduction unit, a transmission system, and conveying wheels. At the left and right ends of the main frame, there are pivoted conveying wheels each equipped with a V-shaped groove. The motor drives large sprockets on the left and right conveying wheel shafts via a master sprocket set on the speed-reduction unit. A pressure roller frame is fixedly mounted on the main frame; above the two V-shaped conveying wheels, this pressure roller frame is fitted with two adjustable-height left and right pressure rollers. The pressure roller frame includes a metal frame, a left crank assembly and a right crank assembly, as well as left and right adjusting screws and an intermediate ratchet mechanism. By rotating the ratchet, the length of the adjusting screws can be adjusted, and through the crank assemblies, the heights of the left and right pressure rollers can be precisely regulated, thereby controlling the clamping force exerted by the pressure rollers on the cable.

Tensioning Machine Maintenance Procedures

I. When using the tensioner daily, the following checks must be performed: 1) Check the levels and quality of fuel oil, lubricating oil, and hydraulic oil. 2) Inspect the operational performance and gear-shifting conditions of the internal combustion engine, transmission mechanism, and actuator, as well as the set positions of the variable mechanisms. 3) Verify the reliability of the parking brake. 4) Check the sensitivity and accuracy of the instruments. 5) Inspect the pressures of the engine oil, replenishing oil, and brake fluid. 6) Examine the anchoring condition of the machine body and its grounding status. 7) Check the pressure-holding performance of the tensioner’s tension control valve (relief valve). The tensioner’s tension control valve should be cleaned and inspected regularly. II. When transporting the tensioner over short distances, it can be towed. The towing speed must meet the following requirements: On flat roads, the speed shall not exceed 30 km/h; on uneven roads, the speed shall not exceed 15 km/h. Additionally, before transportation, the roads and bridges should be inspected, and if necessary, repaired or reinforced. Furthermore, all movable components on the machine body must be temporarily secured. Therefore, lifting should be done using the lifting rings (holes) provided on the machine body.

What is a cable conveyor?

A cable conveyor is an electrically powered machine used for laying power cables (or communication cables). It can be used in conjunction with cable pulling machines, hoists, and other cable-laying equipment, offering convenient and rapid construction. This approach significantly saves labor and material resources, thereby effectively reducing construction costs. Thanks to the long-term efforts of our factory’s technical staff, we are now capable of manufacturing 15 major categories and over 300 varieties of maintenance and construction tools, as well as emergency repair tools, covering power supply, substation, and distribution applications. Our products feature practicality, reliable quality and safety, rational design, and lightweight characteristics. Over the years, our products have enjoyed strong sales across more than 30 provinces, municipalities, and autonomous regions nationwide, serving over a thousand organizations and receiving widespread acclaim from users.

What is a motorized winch?

An engine-powered winch is a construction tool used for erecting overhead high-voltage transmission lines and laying underground cables. It enables smooth and convenient lifting and pulling operations—such as assembling steel towers and stringing conductors (and ground wires)—even under various complex conditions. Engine-powered winches are categorized into diesel-powered winches and gasoline-powered winches, and further divided into hand-carried and wheeled types.
