DETAILED DESCRIPTION

[0025] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0027] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. The present application provides the following embodiments.

[0028] As Figure 1As shown, this is a structural schematic diagram of the tubular busbar handling equipment in this embodiment. This handling equipment can stably support the tubular busbar, and it supports the top of the tubular busbar without requiring manual pressing or support from the operator. It can also safely unload the tubular busbar during subsequent unloading, improving the overall working quality of the handling equipment. The handling equipment includes a base 1 and a handle 2. The handle 2 is installed at the end of the base 1. The operator pushes the base 1 to its entire position using the handle 2. A clamping mechanism 3 is installed on the base 1 to stably support and hold the tubular busbar. When the tubular busbar is transported to… Once the target position is reached, the cable can be safely disengaged from the clamping mechanism 3. When the clamping mechanism 3 is docked with the tubular busbar, the angle of the handle 2 is raised, causing the base 1 to change the overall angle of the clamping mechanism 3, which facilitates the docking of the clamping mechanism 3 with the tubular busbar. After docking, the handle 2 is pressed, and the handle 2 is used as a lever to move the tubular busbar from the shelf to the clamping mechanism 3. When the inertial busbar is transported to the target position, the handle 2 is raised again to shorten the distance between the clamping mechanism 3 and the ground, which facilitates the stable movement of the tubular busbar to the ground at the target position, thus achieving stable transportation of the tubular busbar.

When the base plate 11 is in a parallel state, the support frame 13 does not directly contact the ground. When the base plate 11 tilts towards the side closer to the support frame 13, the support frame 13 limits the minimum deflection angle of the base plate 11.

[0033] As shown in the accompanying drawings Figure 5As shown, it is the structure schematic view of the push-pull mechanism 4 in the embodiment, and also includes the push-pull mechanism 4, which includes the limiting frame 41, the push-pull rod 42 and the elastic push block 43. The limiting frame 41 is symmetrically installed on one side of the upper surface of the base 1, the push-pull rod 42 is slidably installed in the limiting frame 41, one end of the push-pull rod 42 is provided with the elastic push block 43, the elastic push block 43 is in extrusion contact with the end of the push-pull touch block 345, the other end of the push-pull rod 42 is provided with the push-pull handle 44.

With the elasticity of the elastic push block 43, the length of the elastic push block 43 is contracted and deformed as the push-pull rod 42 continues to move, so that the elastic push block 43 moves to the other side of the push-pull touch block 345. When the tubular bus moves to the lower supporting ring 31, the upper pressing ring 32 is attached to the upper surface of the tubular bus at this time. At this time, the push-pull handle 44 is pushed to drive the elastic push block 43 to move the angle of the push-pull touch block 345, so that the extrusion trapezoidal plate 343 moves to the side close to the clamping teeth 33. At this time, the extrusion trapezoidal plate 343 is clamped with the clamping teeth 33 to limit the movement range of the clamping teeth 33. At this time, the clamping teeth 33 can only deflect to the side close to the tubular bus, which strengthens the stability and safety of the tubular bus during transportation, and the operator does not need to manually press or position the top end of the tubular bus.

[0034] It is worth noting that when discharging the tubular bus on the lower supporting ring 31, the push-pull handle 44 is pulled to contact the clamping of the extrusion trapezoidal plate 343 and the clamping teeth 33, the operator stands on the side close to the handle piece 2 to rotate the upper pressing ring 32, and then tilts the overall angle of the base 1 to make the tubular bus directly roll out of the lower supporting ring 31, realizing the safe discharge of the tubular bus.

The fitting ring 51 is installed on one side of the upper surface of the base 1 relative to the push-pull mechanism 4. The anti-skid rubber layer 52 is equidistantly installed on the inner wall of the fitting ring 51.

When in use, the two ends of the tubular bus are limited by the simultaneous operation of the two groups of carrying equipment, preventing the tubular bus from sliding horizontally in the lower support ring 31. The expansion plate 53 is installed on the side wall of the fitting ring 51. The expansion plate 53 is installed at the end of the expansion plate 53. The blocking plate 55 is in extrusion contact with the end of the tubular bus, limiting the movement direction of the tubular bus.
