Technical Field

[0001] The utility model relates to the technical field of switch cabinet handling devices, in particular to an auxiliary unloading device for a switch cabinet. Background Art

[0002] The traditional "trailer + steel pipe rail + manual" method of transporting and assembling switch cabinets requires a large number of operators, high labor intensity, low work efficiency, and major safety hazards during the construction process, which can easily cause cabinet rollover, equipment damage, cabinet shell deformation, cabinet paint peeling, cement floor damage, steel foundation frame damage, cable trench damage, and construction worker injuries.

[0003] The inventor team disclosed an automatic switch cabinet transport and assembly device and operation method in CN117184861A. The device can effectively improve the efficiency of switch cabinet transport and assembly, greatly save manpower and material resources, improve the safety of switch cabinet assembly, and greatly reduce the occurrence of personal injury accidents.

[0004] However, when the device in CN117184861A is unloading the switch cabinet from the device by transferring it to the installation location, it is necessary to use external force to unload the switch cabinet from the device. Therefore, a switch cabinet auxiliary unloading device is designed to solve the above problem. Utility Model Content

[0005] The main purpose of the utility model is to provide a switch cabinet auxiliary unloading device, which can be used in conjunction with the switch cabinet automatic transport and placement device. When in use, the supporting feet of the device are pressed against the edge of a suitable slot on the ground, and the handle is shaken to make the front end of the telescopic rod press against the switch cabinet. After tightening, the handle is released, and the switch cabinet automatic transport and placement device is started to retreat. The device presses the switch cabinet so that it does not retreat with the switch cabinet automatic transport and placement device, and the switch cabinet can be automatically unloaded at the installation position. In addition, the device has a simple structure and low cost, and can conveniently unload the switch cabinet.

[0006] In order to realize the above-mentioned technical features, the purpose of the utility model is realized as follows: a switch cabinet auxiliary unloading device comprises a support rod, a supporting foot is installed at the rear end of the support rod, a support is fixedly installed at the front end, a telescopic rod is installed on the support, and the telescopic rod is freely sleeved in the support rod hole, a handle is installed on the support through a pin shaft, a shift block is connected to a connecting plate through a pin shaft, the other end of the connecting plate is installed on the handle through a pin shaft, a spring 1 is installed between the shift block and the vertical plate at the front end of the support, a locking block is installed at the rear end of the support, and the locking block is connected to the front end of the support rod through a spring 2.

[0007] The support rod is a hollow steel pipe, and the support foot is connected to the rear end of the support rod through a pin shaft and can rotate around the pin shaft within a certain angle.

[0008] The support is fixedly connected to the lower part of the front end of the support rod, and a circular hole is opened on the vertical plate at the front end of the support rod, and the circular hole is used for passing the telescopic rod.

[0032] See also Figure 1-5A switch cabinet auxiliary unloading device includes a support rod 1, a supporting foot 2 is installed at the rear end of the support rod 1, a support 3 is fixedly installed at the front end, a telescopic rod 4 is installed on the support 3, and the telescopic rod 4 is freely sleeved in the hole of the support rod 1, a handle 5 is installed on the support 3 through a pin shaft, a shift block 7 is connected to a connecting plate 6 through a pin shaft, and the other end of the connecting plate 6 is installed on the handle 5 through a pin shaft, a spring 1 8 is installed between the shift block 7 and the vertical plate at the front end of the support 3, a locking block 9 is installed at the rear end of the support 3, and the locking block 9 is connected to the front end of the support rod 1 through a spring 2 10. By adopting the above-mentioned auxiliary unloading device, it can be used in conjunction with the switch cabinet automatic transport and positioning device. When in use, the supporting feet of the device are pressed against the edges of suitable slots on the ground, and the handle is shaken to make the front end of the telescopic rod press against the switch cabinet. After tightening, the handle is released, and the switch cabinet automatic transport and positioning device is started to retreat. The device presses the switch cabinet so that it does not retreat with the switch cabinet automatic transport and positioning device, and the switch cabinet can be automatically unloaded at the installation position. In addition, the device has a simple structure and low cost, and can easily unload the switch cabinet.

[0033] Furthermore, the support rod 1 is a hollow steel tube, and the support foot 2 is connected to the rear end of the support rod 1 through a pin and can rotate around the pin within a certain angle. The support rod 1 facilitates the telescopic rod 4 to slide inside it, thereby achieving telescopic adjustment of the telescopic rod 4, and the support foot 2 facilitates the rear end of the support rod 1 to be positioned and supported on the slot 14.

[0034] Further, the support 3 is fixedly connected to the lower front end of the support rod 1, and a circular hole 301 is opened on the vertical plate at the front end of the support 3, and the circular hole 301 is used to pass the telescopic rod 4. The support 3 facilitates the installation of the handle 5, the shift block 7 and the connecting plate 6.

[0035] Furthermore, the surface of the telescopic rod 4 is processed with grooves 402 with equal spacing, and a baffle 401 is provided at the front end. The baffle 401 is used to press against the switch cabinet body, and the telescopic rod 4 freely passes through the vertical plate, spring 1 8, and shift block 7 at the front end of the support 3 and is sleeved in the support rod 1. By adopting the above-mentioned telescopic rod 4, it is convenient to cooperate with the one-way driving mechanism composed of the shift block 7, the connecting plate 6 and the handle 5, and then drive the telescopic rod 4 to extend along the support rod 1, and then adjust the length to ensure that it can be reliably supported on the outer wall of the switch cabinet 11. The groove 402 is convenient to cooperate with the shift block 7 to provide driving force.

[0036] Furthermore, the handle 5 is hinged on the support 3 through a pin, and the shift block 7 is connected to the handle 5 through a pin and a connecting plate 6. When the handle is stationary, the shift block 7 and the axis of the telescopic rod 4 remain perpendicular. Shaking the handle 5 can tilt the shift block 7 forward, shift the telescopic rod 4 outward, and prevent the telescopic rod 4 from retreating through the locking block 9; when the handle 5 is released, the shift block 7 is reset by a spring 8 and remains perpendicular to the axis of the telescopic rod 4. The handle 5 can be used to provide the power for telescopic movement.

[0037] Furthermore, the shift block 7 is processed with a first through hole 701 for passing the telescopic rod 4, and the bottom end of the shift block 7 forms a sliding fit with the slide groove 302 on the support 3. The shift block 7 can drive the telescopic rod 4 to extend under the cooperation of the first through hole 701 and the groove 402.

[0038] Furthermore, the lower part of the locking block 9 is inserted into the square groove 303 of the support 3, and is connected to the support rod 1 through the spring 2 10. The spring 2 10 always pulls the locking block 9 to make it in a locked state; when the telescopic rod 4 is to be retracted, the locking block 9 is pushed forward to make it in a vertical state, and the telescopic rod 4 is pushed to retract, and the locking block 9 is released to lock the telescopic rod 4. The above-mentioned locking block 9 can achieve the purpose of self-locking the telescopic rod 4. The locking block 9 is processed with a circular hole for passing the telescopic rod 4. The circular hole cooperates with the groove 402, and the locking block 9 is tilted under the tension of the spring 2 10, thereby locking the telescopic rod 4. When it is necessary to unlock, it is only necessary to pull the locking block 9 so that the telescopic rod 4 can pass through the circular hole smoothly, and then retract the telescopic rod 4.
