Description

Technical Field

[0001] The invention belongs to the technical field of electromechanical construction, and in particular relates to a cable laying device. Background Art

[0002] In electromechanical construction, indoor cables are typically installed on the ceiling using cable bridges. As a cable support structure, cable bridges neatly secure cables in designated locations, preventing them from hanging haphazardly or being scattered, making cable laying and management much more convenient. Cable maintenance and repair are inevitable in electrical systems. Cable bridges clearly indicate the route and location of cables, allowing maintenance personnel to quickly locate and address any issues. They also provide ample space for maintenance personnel, improving work efficiency. This neat wiring method is not only aesthetically pleasing but also facilitates heat dissipation and ventilation for the cables, reducing safety hazards caused by overheating. Currently, cable bridges typically utilize a U-shaped structure. Cable laying requires manual movement into the grooves on the bridge, which is inconvenient and poses safety risks due to the high-altitude work involved. Summary of the Invention

[0003] The object of the present invention is to provide a cable laying device which uses a scissor lift platform to assist manual cable laying.

[0004] The present invention is achieved by the following measures: a cable laying device, characterized by comprising a scissor lift platform, a cable pay-out structure and a cable upper bridge structure arranged on the platform of the scissor lift platform; Material toggling mechanism, its both ends are to be connected multiple times by two guide wheels, and the guide wheels are connected multiple times by two guide wheels, and abut against each other to form a round shank and a gear. A cam in contact with the roller is fixedly provided at one end of the rotating shaft close to the bridge, and the contact surface between the cam and the roller includes a small sector portion and a large sector portion concentric with the rotating shaft, and the small sector portion and the large sector portion are connected by two symmetrically arranged arc portions; a limit plate is concentrically provided on the outer end surface of the cam, and a sector-shaped boss is fixedly provided on the outer end surface of the limit plate, and the outer end surface of the sector-shaped boss transitions to the outer end of the limit plate through an arc, and the sector-shaped boss is flush with the side surface of the large sector portion, and the outer end surfaces of the sector boss and the limit plate can contact the sphere; A vertical rod is fixed on the driving rod, a support rod facing the bridge is fixed on the outer side of the vertical rod, a U-shaped frame is fixed on the outer end of the support rod, a vertical roller is rotatably provided between the two side plates of the U-shaped frame, and ear plates are fixed on the outer sides of the two side plates, and horizontal rollers are rotatably provided on the ear plates; When the sphere contacts the outer end surface of the limit plate, the roller contacts the small fan-shaped part and the spring is not compressed; when the shaft rotates and the roller contacts the large fan-shaped part, the sphere begins to contact the outer end surface of the fan-shaped boss, and after the drive rod is lifted, the spring is compressed, and the horizontal roller located below is lifted to a height higher than the side of the bridge and moves from the top of the bridge toward the bridge.

[0005] The motor is fixed to the base plate, and the motor shaft of the motor is connected to the shaft via a transmission mechanism, which can be a belt drive or a chain drive.

[0006] The cable pay-out structure includes a base and columns fixedly arranged on both sides of the base, a placing table is fixedly arranged on the upper ends of the two columns, a driving shaft is rotatably arranged on the two placing tables, a cable reel is sleeved on the driving shaft, and the cable is fixed to the driving shaft by screws.

[0007] 6. The placement platform is rotatably provided with two guide wheels, each axis being parallel to the axis of the drive shaft. The drive shaft is disposed between and tangential to the two guide wheels. A stop plate is provided on the drive shaft, located outside the guide wheels, to prevent the drive shaft from separating from the two guide wheels. A stop block is fixed to the placement platform via screws above the end of the drive shaft. The stop block prevents the drive shaft from separating from the placement platform and is detachably connected, facilitating the replacement of the cable reel at any time.

[0008] A cable limiter is provided between the cable unwinding structure and the cable upper bridge structure. The cable limiter comprises a support column and a circular ring fixedly provided above the support column. The inner side wall of the circular ring is circumferentially evenly distributed with a number of bull's eye bearings. The spacing between two adjacent bull's eye bearings is smaller than the outer diameter of the cable, and the height of the circular ring is lower than the bridge. This can prevent the cable from being squeezed between the two bull's eye bearings. The support column is fixed on the platform of the scissor lift platform or on the base. The bull's eye bearing is a prior art, and the specific structure will not be described in detail here. The spherical rolling body of the bull's eye bearing can contact the cable, which is convenient for limiting the cable and reducing friction with the outer wall of the cable.

[0009] The scissor lift platform utilizes existing technology and generally includes a frame with drive wheels, a scissor-type frame mounted on the frame, a telescopic rod that drives the scissor-type frame up and down, and a platform mounted on the scissor-type frame. The telescopic rod is typically a hydraulic rod. Depending on the actual situation, appropriate guardrails should be installed around the platform to ensure the safety of users.

[0010] How to use: The coiled cable drum is placed on the drive shaft and secured with screws. One end of the cable is passed through the ring and placed between the vertical roller and two horizontal rollers. It is then secured to the bridge with a cable clamp. The scissor lift platform is moved along the bridge to gradually lay the cable. The drive rod is initially horizontal, with the roller in contact with the small sector and the ball in contact with the outer end surface of the limit plate.

[0011] When it moves to the specified position, the motor is started, and the motor drives the rotating shaft to rotate through the transmission mechanism. The rotation drives the cam and the limit plate to rotate. When the roller contacts the large fan-shaped part on the cam, the ball contacts the fan-shaped boss. At this time, the drive plate is lifted and moves toward the bridge. The cables located on the vertical roller and the two horizontal rollers are located above the bridge, which makes it convenient to lay the cables. The technical solution provided by the embodiments of the present invention has the beneficial effect of assisting manual laying of cables on the bridge. During the laying process, the scissor lift platform can move along the bridge, gradually moving the cables to the bridge for fixing before further laying. At this time, the cables do not need to be concentrated on the bridge but are located outside the bridge, which facilitates construction. During laying, the cables between the vertical roller and the two horizontal rollers are initially located below the bridge, which keeps the cables on the bridge in better contact with the bridge.
