Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a slide rail trolley used for laying cables in a bridge. Background Art

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. Cable laying methods can be divided into overhead, underground (pipeline and direct burial), underwater, wall and tunnel according to different usage scenarios.

[0003] After searching, a Chinese patent with publication number CN219420124U discloses a pulley device for improving the efficiency of cable laying in a bridge frame, including a bridge frame, a load-bearing plate and cables. Universal wheels are installed at the four corners of the bottom outer wall of the load-bearing plate, and directional wheels are installed at both ends of the outer walls on both sides of the load-bearing plate.

[0004] Based on the above search and combined with existing technology findings;

[0005] The above patent uses a pulley device for laying, but still needs to drag the cable, which can easily damage the cable. In the existing cable laying in the bridge, due to the long distance and heavy weight of the cable, dragging the cable in the bridge during construction can easily cause damage to both the bridge and the cable. In addition, the construction is difficult and the work efficiency is low, so there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a slide rail trolley for laying cables in a bridge. The device can be used to install cables, and the slide rail can ensure that no unnecessary damage will be caused to the cables when they are laid.

[0007] The technical solution to achieve the purpose of the utility model is: a slide rail trolley for laying cables in a bridge, comprising a base, a plurality of trolley wheels rotatably mounted on both sides of the base, a plurality of lifting rods fixedly mounted on the surface of the base, a cable bracket fixedly mounted on the telescopic ends of the plurality of lifting rods, a plurality of rollers rotatably mounted on the cable bracket, a pair of support plates fixedly mounted on the surface of the base, and also comprising a winding assembly and a laying assembly.

[0008] The winding assembly includes a winding wheel rotatably mounted between a pair of support plates.

[0009] The laying assembly comprises a slide rail slidably mounted on the retracting and unretracting wheel.

[0010] In some embodiments, a rocker is rotatably passed through one side of one of the support plates, and the end of the rocker is fixedly connected to the retracting and releasing wheel. A track bracket is fixedly installed between a pair of support plates, and a cable tray is provided at the end of the track bracket. A pair of side baffles are fixedly installed at both ends of the track bracket.

[0011] In some embodiments, the slide rail includes multiple rollers 2, each of which has pulleys rotatably installed at both ends, and a traction rope is fixedly connected between the multiple rollers 2. The slide rail is slidably connected between the track bracket and the cable tray.

[0012] In some embodiments, two pairs of grooves are formed at the bottom of the base, an electric telescopic rod is fixedly mounted on the inner top of each groove, and a pad is fixedly mounted on the telescopic end of each electric telescopic rod.

[0013] In some embodiments, a pair of push rods are fixedly mounted near the end of the base.

[0014] Compared with the prior art, the present invention has the following significant advantages:

[0015] First: The utility model lays the cable by setting a retractable wheel and a slide rail composed of a pulley, a roller and a traction rope. After connecting the track bracket to the cable bridge, the cable is installed on the cable bracket, and the unpowered roller is used to ensure smooth cable dragging. The set slide rail can ensure that the bridge and the cable will not be damaged when the cable is dragged. The combination of the pulley and the unpowered roller can realize the three working states of track laying, cable dragging and track recycling, thereby improving the quality of cable laying, reducing the risk of cable damage, and convenient operation, thereby improving the efficiency of construction operations.

[0016] Secondly, the utility model provides an electric telescopic rod and a pad, which can ensure that the entire device is stably supported during cable laying operations, thereby preventing the device from shaking or sliding during laying, thereby affecting the laying of the cable.

[0017] The present invention solves the problem that the above-mentioned patent uses a pulley device for laying cables, but still needs to drag the cables, which can easily damage the cables. In the existing cable laying in the bridge, due to the long distance and heavy cable weight, dragging the cables in the bridge during construction can easily damage both the bridge and the cables, and the construction is difficult and the work efficiency is low.

[0028] Example 1

[0029] like Figure 1-2 As shown, a slide rail trolley for laying cables in a bridge comprises a base 1, a plurality of trolley wheels 2 are rotatably mounted on both sides of the base 1, a plurality of lifting rods 3 are fixedly mounted on the surface of the base 1, a cable bracket 9 is fixedly mounted on the telescopic ends of the plurality of lifting rods 3, a plurality of rollers 10 are rotatably mounted on the cable bracket 9, a pair of support plates 4 are fixedly mounted on the surface of the base 1, and also includes a winding assembly and a laying assembly. The provided base 1 and trolley wheels 2 facilitate the movement of the entire device, the provided cable bracket 9 facilitates the placement of the cable to be laid, and the provided lifting rods 3 can be adjusted according to the on-site construction height, thereby improving the adaptability of the device.

[0030] The winding assembly includes a winding wheel 5 rotatably installed between a pair of support plates 4. The winding wheel 5 can be used to wind up and unfold the auxiliary laying components, thereby improving the operation convenience of the device.

[0031] The laying component includes a slide rail 13 slidably mounted on the retracting wheel 5. The set slide rail 13 can ensure that no unnecessary damage is caused to the cable when the cable is dragged during laying, thereby achieving both cable laying and protection of the cable.

[0032] like Figure 1-2 As shown, a rocker 6 is rotated through one side of one of the support plates 4, and the end of the rocker 6 is fixedly connected to the retracting and releasing wheel 5. A track bracket 7 is fixedly installed between a pair of support plates 4, and a cable bridge 14 is provided at the end of the track bracket 7. A pair of side baffles 8 are fixedly installed at both ends of the track bracket 7. The rocker 6 is provided to facilitate the staff to easily rotate the retracting and releasing wheel 5, thereby realizing the retracting and releasing function. In addition, the track bracket 7 is provided to facilitate support for the slide rail 13, ensuring that the slide rail 13 can slide out of the retracting and releasing wheel 5 normally, and the track bracket 7 of this device has the function of being retractable and adjustable in angle, which can be adjusted according to the height of the cable bridge 14, further improving the adaptability of the device.

[0033] like Figure 1-2 As shown, the slide rail 13 includes multiple rollers 19, and pulleys 12 are rotatably installed at both ends of each roller 19. A traction rope 11 is fixedly connected between the multiple rollers 19. The slide rail 13 is slidably connected between the track bracket 7 and the cable bridge 14. The traction rope 11 can be used to drag the entire slide rail 13 to move, and the cable end is connected to the traction rope 11, so as to achieve an auxiliary effect on cable laying, which is convenient for cable laying. At the same time, since the cable is dragged in a rolling manner, it can protect the cable and prevent damage to the cable during dragging.
