DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings. Example

[0025] like Figure 1-8 As shown, a self-supporting opening and closing conveying mechanism which is convenient for laying power cables comprises a base 1 and a self-supporting opening and closing conveying assembly 2, the self-supporting opening and closing conveying assembly 2 is arranged on the upper side of the base 1, a power cable 3 is arranged inside the self-supporting opening and closing conveying assembly 2, conveying guide wheel seats 4 are arranged on both sides of the self-supporting opening and closing conveying assembly 2, slide plates 5 are arranged below the conveying guide wheel seats 4, the conveying guide wheel seats 4 are slidably connected with the corresponding slide plates 5 through slide blocks 6, and transverse movement assemblies 7 are arranged above the conveying guide wheel seats 4, and the transverse movement assemblies 7 drive the conveying guide wheel seats 4 to move laterally.

[0026] The self-supporting opening and closing conveying assembly 2 includes an upper frame plate 21 and a lower frame plate 22 which are symmetrically arranged in an upper and lower manner. Threaded sleeves 23 are arranged on both sides of the upper frame plate 21 and the lower frame plate 22. A bidirectional lead screw 24 is arranged inside the threaded sleeve 23. A pulley assembly 25 is arranged at the top input end of the bidirectional lead screw 24. The pulley assembly 25 on one side of the upper frame plate 21 is connected to a drive shaft 26, and the drive shaft 26 is dynamically connected to a driver 27.

[0027] A lifting adjustment screw 29 is disposed on the top of the upper frame plate 21 , and a warping triangle conveying mechanism 28 is symmetrically disposed on the inner sides of the upper frame plate 21 and the lower frame plate 22 .

[0028] In the present embodiment, the working principle of the self-supporting opening and closing conveying assembly is as follows: first, the height of the self-supporting opening and closing conveying assembly as a whole can be adjusted by the lifting and adjusting screw rod, so as to realize the state switching of the straight-line transmission of the power cable or the transmission of the power cable at the turning point of the present invention, and the height of the self-supporting opening and closing conveying assembly as a whole can be changed (at this time, the self-supporting opening and closing conveying assembly and the transmission guide wheel seat are not on the same horizontal line), and the distance between the transmission guide wheel seat on both sides and the self-supporting opening and closing conveying assembly can be changed, so as to realize the transmission of the power cable at the turning points of different angles, thereby greatly improving the practicality of the device of the present invention; in addition, the driver can be driven by The shaft drives the pulley assembly to rotate, and the pulley assembly synchronously drives a set of bidirectional lead screws to rotate. Since the bidirectional lead screw cooperates with the threaded sleeve, the upper frame plate and the lower frame plate can be brought closer or farther away from each other through the bidirectional lead screw, thereby realizing the change of the distance between the upper frame plate and the lower frame plate. On the one hand, adaptive adjustment can be made through power cables of different specifications, which is convenient for application to cables of various specifications and has good versatility. On the other hand, by adjusting the distance between the upper frame plate and the lower frame plate, it is convenient to adjust the distance between the warped triangle conveying mechanism, so that a group of conveyor belts and the power cables located between a group of conveyor belts can be effectively fitted and tightly attached, thereby greatly improving the conveying effect.

[0029] The warped triangle conveying mechanism 28 includes a skeleton 81, and a first load wheel assembly 82 and a second load wheel assembly 83 are respectively arranged on both sides below the skeleton 81.

The conveyor belt 88 is located at the first roller assembly 82 and the second roller assembly 83 as a horizontal conveying part, and is located at the first roller assembly 82 and the tensioning wheel assembly 84 as an inclined warping part 89.

In addition, it can better cooperate with the steering conveying arc formed by the self-supporting opening and closing conveying assembly and the conveying guide wheel seats on both sides to ensure smooth, stable and reliable conveying. Furthermore, a number of oblique inward-retracting grooves are evenly spaced on both sides of the outer surface of the conveyor belt. The oblique inward-retracting grooves can ensure that the power cable is always on the inside of the conveyor belt during conveyance, avoid the power cable from deviating to both sides during conveyance, avoid the power cable from detaching from the conveyor belt, and ensure that the conveying process is stable, reliable and safe.
