Description

Technical Field

[0001] The utility model relates to the technical field of electrical construction, in particular to a hoisting frame for electrical construction. Background Technique

[0002] Electrical equipment is often designed to be huge in volume and heavy in weight, so a hoisting frame is needed to lift heavy electrical equipment such as electrical cabinets.

[0003] However, in the prior art, it is difficult for the hoisting frame to maintain absolute horizontal stability during the hoisting process, which may cause the electrical equipment placed inside to collide with the hoisting frame, resulting in damage to the electrical equipment. Moreover, the hoisting frame lacks a falling buffer structure and has poor buffer protection performance. Therefore, we propose a hoisting frame for electrical construction. Content of the Utility Model

[0004] The utility model provides a hoisting frame for electrical construction, which solves the above-mentioned technical problems.

[0005] The solution of the utility model to the above technical problems is as follows: A hoisting frame for electrical construction includes a concave-shaped hoisting lower shell. The inner bottom surface of the hoisting lower shell is horizontally and fixedly installed with a concave-shaped mounting plate through a plurality of vertically arranged support columns. Four chutes penetrating the mounting plate are opened on the upper end surface of the mounting plate. A moving rack is slidably installed on the inner side wall of the chute. The moving rack is fixedly connected to the inner side wall of the hoisting lower shell or the inner side wall of the mounting plate through a horizontally arranged telescopic rod. A first spring is movably sleeved on the outer side wall of the telescopic rod. A clamping plate is fixedly installed at the end of the moving rack. A limiting mechanism is installed on the hoisting lower shell, and a protection plate is installed on the hoisting lower shell through a buffer mechanism.

[0006] Preferably, the limiting mechanism includes a motor vertically and fixedly installed on the inner bottom surface of the hoisting lower shell. A screw rod is vertically and fixedly installed on the output shaft of the motor. An adapter plate is threadedly sleeved on the outer side wall of the screw rod. The adapter plate is movably sleeved on the outer side wall of the support column. Four limiting racks are horizontally and fixedly installed on the upper end surface of the adapter plate. The limiting racks correspond to the moving racks one by one up and down.

[0007] Preferably, the buffer mechanism includes a connecting rod vertically and fixedly installed at the corner of the upper end surface of the protection plate. A limiting block is fixedly installed at the upper end of the connecting rod. The connecting rod movably penetrates the hoisting lower shell. The hoisting lower shell is fixedly connected to the protection plate through a second spring movably sleeved on the outer side wall of the connecting rod.

[0008] Preferably, a U-shaped hoisting upper shell is rotatably installed on the upper part of the side wall of the hoisting lower shell through a hinge. The hoisting lower shell is fixedly connected to the hoisting upper shell through screws.

[0009] Preferably, two hoisting members are fixedly installed on the outer side walls of both sides of the lower hoisting housing respectively.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. By arranging multiple clamping plates, the first spring pushes the moving rack and indirectly drives the clamping plate to move, so that the clamping plate fits with the electrical equipment placed on the mounting plate. The motor is used in cooperation with the screw rod to indirectly drive the limiting rack to move upward, and the limiting rack cooperates with the moving rack for limiting and fixing, indirectly ensuring the stable clamping and fixing of the clamping plate, preventing the electrical equipment from shifting and colliding with the device components, and protecting the electrical equipment.

[0012] 2. By arranging the protection plate, the connecting rod is set to realize the connection between the protection plate and the lower hoisting housing. At the same time, the second spring is sleeved outside the connecting rod, and the second spring is used for floor buffer protection to reduce the impact on the internal electrical equipment when the device accidentally drops.

[0024] Embodiment 1

[0025] As Figures 1-6As shown in the figure, a hoisting rack for electrical construction of the utility model includes a concave-shaped hoisting lower housing 1. The upper part of the side wall of the hoisting lower housing 1 is rotatably installed with a door-shaped hoisting upper housing 16 through a hinge. The hoisting lower housing 1 is fixedly connected with the hoisting upper housing 16 by screws. Two hoisting members 17 are respectively fixedly installed on the outer side walls of both sides of the hoisting lower housing 1. A concave-shaped mounting plate 3 is horizontally fixedly installed on the inner bottom surface of the hoisting lower housing 1 through multiple vertically arranged support columns 2. Four through grooves 4 are opened on the upper end surface of the mounting plate 3. A moving rack 5 is slidably installed on the inner side wall of the through groove 4. The moving rack 5 is fixedly connected with the inner side wall of the hoisting lower housing 1 or the inner side wall of the mounting plate 3 through a horizontally arranged telescopic rod 6. A first spring 7 is movably sleeved on the outer side wall of the telescopic rod 6. The first spring 7 indirectly drives the clamping plate 8 to move to ensure that the clamping plate 8 is in tight contact with the electrical equipment. A clamping plate 8 is fixedly installed at the end of the moving rack 5. A limiting mechanism is installed on the hoisting lower housing 1. The hoisting lower housing 1 is installed with a protection plate 9 through a buffer mechanism. The buffer mechanism includes a connecting rod 14 vertically and fixedly installed at the corner of the upper end surface of the protection plate 9. A limiting block is fixedly installed at the upper end of the connecting rod 14. The connecting rod 14 movably penetrates through the hoisting lower housing 1. The hoisting lower housing 1 is fixedly connected with the protection plate 9 through a second spring 15 movably sleeved on the outer side wall of the connecting rod 14. When the device accidentally falls to the ground, the protection plate 9 moves upward relative to the hoisting lower housing 1, and the second spring 15 is compressed. The second spring 15 provides a reaction force to buffer and protect the electrical equipment in the device. The device clamps and fixes the electrical equipment through components such as the clamping plate 8 arranged in the hoisting lower housing 1, avoiding the electrical equipment from shifting and colliding with the components, and having stronger safety performance.

[0026] Embodiment 2

[0027] As Figure 3 shown, the limiting mechanism includes a motor 10 vertically and fixedly installed on the inner bottom surface of the hoisting lower housing 1. A screw rod 11 is vertically fixedly installed on the output shaft of the motor 10. An adapter plate 12 is threadedly sleeved on the outer side wall of the screw rod 11. The adapter plate 12 is movably sleeved on the outer side wall of the support column 2. Four limiting racks 13 are horizontally fixedly installed on the upper end surface of the adapter plate 12. The limiting racks 13 correspond to the moving racks 5 one by one up and down. The motor 10 adopts a servo motor that can rotate forward and backward. When the electrical equipment is placed on the mounting plate 3 and after ensuring that the clamping plate 8 is in tight contact with the electrical equipment, control the motor 10 to drive the screw rod 11 to rotate forward. The screw rod 11 drives the adapter plate 12 and the limiting racks 13 to move upward. The limiting racks 13 are engaged with the upper moving racks 5 for limiting to ensure the stable clamping and fixing of the clamping plate 8.

[0028] Working principle:

[0029] In use, after separating multiple clamping plates 8, place the electrical equipment on the mounting plate 3. The first spring 7 pushes the moving rack 5 towards the electrical equipment. The moving rack 5 drives the clamping plates 8 to move synchronously and makes the clamping plates 8 fit with the electrical equipment. Then, control the motor 10 to drive the screw 11 to rotate forward. The screw 11 drives the connecting plate 12 and the limit rack 13 to move upward. The limit rack 13 moves upward and docks and meshes with the corresponding moving rack 5. The limit rack 13 indirectly limits and fixes the clamping plates 8. Then, the hoisting upper shell 16 can be rotated and closed and fixed with screws. Then, tie the rope to the hoisting frame 17 for hoisting.

[0030] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technical personnel in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and described above; however, any equivalent changes made by those skilled in the art in the technical scope of the present invention without departing from the technical solution of the present invention, using the technical content disclosed above, such as slight modifications, decorations, and evolutions, are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
