Description

TECHNICAL FIELD

[0001] The utility model relates to cable laying technical field, concretely is a street lamp cable laying device. BACKGROUND

[0002] In the process of laying the street lamp cable, the cable is generally wound on a winding wheel, and then the winding wheel is driven to rotate by pulling the cable, so that the cable is unwound and laid.

[0003] However, the cable of the street lamp is generally long and thick, and it is time-consuming and laborious to lay the cable manually. Therefore, a cable conveyor is generally used. The cable conveyor is a device that uses a motor as a driving force to cooperate with a conveying mechanism and a limiting mechanism to transport the cable. The cable conveyor can cooperate with the winding wheel to place the cable at a designated laying position more quickly. The device is one of the main devices for laying the street lamp cable and some long cables.

[0004] However, the cable laying device mainly uses a conveyor belt to transport the cable, and the limiting effect of the conveyor belt on the cable is poor. In mountainous rural road construction, the mountain roads are rugged and have many uphill sections. When the cable is transported on the uphill section, the cable is prone to slipping between the conveyor belt. When this phenomenon occurs, the conveyor belt and the cable will rub against each other, which will cause damage to the surface of the cable and the conveyor belt. Therefore, we propose a street lamp cable laying device. UTILITY MODEL CONTENTS

[0009] Preferably, the clamping rods are provided with a plurality of sliding grooves, half-ring-shaped rough surface plates are slidingly connected in the sliding grooves, the surfaces of the rough surface plates are provided with tiny particles that increase roughness, and damping sheets are arranged between the rough surface plates and the sliding grooves.

[0010] Preferably, the two sides of the load-bearing frame are fixedly connected with fixed frames, a cross frame is slidingly connected between the fixed frames, threaded rods are threadedly connected to both ends of the cross frame away from the fixed frames, limiting frames are rotationally connected to the bottom ends of the threaded rods, pulleys are rotationally connected between the two ends of the limiting frames, a guide frame is fixedly connected between the two limiting frames, and the guide frame is slidingly connected with the same side fixed frame.

[0011] Preferably, the two ends of the load-bearing frame are fixedly connected with fixed plates, the top surfaces of the fixed plates are flush with the top surface of the conveying belt, and two rotationally connected rotating rods are arranged on the fixed plates.

[0012] Preferably, knobs are threadedly connected to the connecting ends of the cross frame and the fixed frame, and handles are fixedly connected to the top ends of the threaded rods.

[0013] Preferably, a motor for driving the movement of the conveying belt is fixedly connected to one side of the load-bearing frame, a controller is fixedly connected to the load-bearing frame, and the controller is connected with the motor through a signal line.

[0014] Compared with the prior art, the utility model has the advantages that:

[0015] 1. In this invention, after the cable is placed on the conveyor belt, the cable will press against the limiting block, causing the limiting block to descend. The limiting block will then pull the traction rope, which in turn drives the gear to rotate. The gear engages with the rack at the bottom of the rack plate, causing the rack plate, mounting base, V-shaped bracket, and clamping rod to move towards the cable. When the clamping rod abuts against the surface of the cable, it clamps and limits the cable's position. This design prevents slippage between the cable and the conveyor belt during transport. When the base above the conveyor belt moves to below the conveyor belt, the pressure exerted by the cable on the limiting block disappears, the spring begins to rebound, and the limiting block moves back to its original position. During the process of the limiting block moving back to its original position, the tension on the traction rope is relaxed, and the spring begins to rebound, driving the gear to rotate in the opposite direction while winding up the traction rope. At this time, the reverse gear drives the rack plate, mounting base, V-shaped frame and clamping rod back to their original positions, which facilitates repeated clamping and fixing of the cable in subsequent work, further improving the auxiliary function of the device in the cable conveying process.

[0016] 2. When conveying cables of different models, this utility model allows for the rotation of a specified number of rough panels on the clamping rod according to the cable's diameter and weight. This allows the specified number of rough panels to come into contact with the cable, increasing the friction between the clamping rod and the cable and further improving the stability of the clamping rod on the cable. At the same time, because the surface of the rough panels is relatively rough, by adjusting the number of rough panels in contact with the cable, the clamping rod can stably limit the cable while minimizing the friction between the clamping rod and the cable, further improving the protection of the cable during the conveying process.

[0031] The accompanying drawings are included to provide a further understanding of the application, and are incorporated herein and constitute a part of this application. Figure 1 As shown, the two ends of the load-bearing frame 1 are fixedly connected with the fixed plates 4, and the top surface of the fixed plate 4 is flush with the top surface of the conveyor belt 2. The fixed plate 4 is installed with two rotatingly connected rotating rods 41.

[0032] Further, when placing the cable, the cable is placed between the two rotating rods 41, at this time the rotating rods 41 cooperate with each other while the conveyor belt 2 is conveying the cable, so as to horizontally limit the cable parts located at the two ends of the load-bearing frame 1, so that the cable is always located at the middle position of the conveyor belt 2 during the conveying process, avoiding the cable from being combined with the load-bearing frame 1 body, so as to avoid the problem that the surface of the cable is rubbed with the load-bearing frame 1 during the conveying process, causing damage.

[0033] Working principle: first, install the device at the designated working position, then power on the device to prepare for the cable conveying work. Before conveying the cable, according to the diameter and weight of the cable, rotate the corresponding number of rough plates 262 to face the cable, so as to control the friction between the clamping rod 26 and the cable, and then the cable conveying work can be carried out.

[0034] First, the cable is placed at the middle position of the limiting block 22, at this time the cable will press the limiting block 22, the limiting block 22 will descend after being pressed, and will compress the spring 221 to shrink. During the descending process of the limiting block 22, the limiting block 22 can pull the traction rope 28, the traction rope 28 can drive the mounting rod 27 to rotate when being pulled, at this time the two ends of the mounting rod 27 will drive the clockwork 273 to tighten while driving the gear 271 to rotate, and at this time the rotating gear 271 will cooperate with the rack on the bottom of the rack plate 23 to drive the rack plate 23, the mounting seat 24, the V-shaped frame 25 and the clamping rod 26 to move towards the cable, when the clamping rod 26 abuts against the cable, the clamping rod 26 can clamp and limit the cable, and when placing the cable, the cable is ensured to be placed between the two rotating rods 41.

[0035] After that, the screw rod 33 is rotated by rotating the handle 34, and the rotating screw rod 33 will descend along the cross 31, at this time, the screw rod 33 will drive the limiting frame 35 and the pulley 36 to descend synchronously, when the arc-shaped groove of the pulley 36 contacts with the top of the cable, the rotation is stopped;

[0036] At this time, the motor 11 is started by the controller 12, and the transmission belt 2 is driven to move, and the cable can be conveyed by the transmission belt 2 at this time, in this process, the rotating rods 41 cooperate with each other, and the cable parts located at both ends of the supporting frame 1 are transversely limited, so that the cable is always located in the middle position of the transmission belt 2 during the conveying process, and the pulley 36 is driven to rotate when the cable is conveyed, and the pulley 36 can provide a certain limiting effect for the cable without affecting the conveying work of the cable, so that the cable is more stable during the conveying process.

[0037] When the base 21 moves to the lower side of the transmission belt 2, the extrusion force of the cable on the limiting block 22 disappears at this time, the spring 221 rebounds to drive the limiting block 22 to lift, and the limiting block 22 lifts the traction rope 28 during the lifting process, and the spring 273 starts to rebound when the limiting effect of the mounting rod 27 disappears, and drives the mounting rod 27 to rotate reversely, the gear 271 rotates reversely synchronously with the mounting rod 27, and the gear 271 drives the rack plate 23, the mounting seat 24, the V-shaped frame 25 and the clamping rod 26 to move towards the side wall of the storage slot 211, until they return to the original position, when the base 21 moves to the upper side of the transmission belt 2 again, the cable can be clamped and fixed again, so that the cable can be automatically clamped repeatedly during the conveying work, and the stability between the cable and the transmission belt 2 is improved.
