Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a hoisting mechanism for a power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box), which is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. The installation requirements of the distribution board (box) are: the distribution board (box) should be made of non-combustible materials; open distribution boards can be installed in production places and offices with low risk of electric shock; closed cabinets should be installed in places such as processing workshops, castings, forgings, heat treatments, boiler rooms, and woodworking rooms where the risk of electric shock is high or the working environment is poor; in dangerous workplaces with conductive dust or the generation of flammable and explosive gases, closed or explosion-proof electrical facilities must be installed; the electrical components, instruments, switches and lines of the distribution board (box) should be arranged neatly, installed firmly, and easy to operate. The bottom surface of the floor-mounted board (box) should be 5 to 10 mm above the ground; the center height of the operating handle is generally 1.2 to 1.5 m; there are no obstacles within 0.8 to 1.2 m in front of the board (box); the protective wire connection is reliable; no bare live parts should be exposed outside the board (box); electrical components that must be installed on the outer surface of the board (box) or on the distribution board must have reliable shielding.

[0003] A power distribution cabinet convenient for lifting is disclosed in the Chinese utility model patent application disclosure CN210744495U, which relates to the technical field of power distribution cabinets, including a cabinet body, and also including a lifting piece with a sliding hole. A fixed rod inserted through the sliding hole is fixed on the inner wall of the cabinet body, and the upper surface of the cabinet body is provided with an insertion hole. The lifting piece includes an extended end that can be inserted through the insertion hole and a supporting end whose length is greater than the insertion hole and cannot pass through the insertion hole, and a lifting hole is provided on the extended end. The utility model adopts the above technical solution. When the power distribution cabinet needs to be moved, the sliding block is moved in the direction away from the clamping hole, and the sliding block drives the plug rod away from the clamping hole. At this time, the spring is in a compressed state. Then pull the extended end to align the clamping hole with the plug rod, release the sliding block, and the sliding block pushes the plug rod into the insertion hole under the action of the spring elastic force. Finally, wait for the lifting device to hook the lifting hole to move the power distribution cabinet, so that it is not necessary to hold the lifting piece by hand and wait for the lifting device to come and hook the lifting hole, which is more labor-saving.

[0004] However, due to the high height of the distribution cabinet, workers need to climb to the top of the distribution cabinet with the help of a ladder when hoisting it, which is time-consuming, labor-intensive and affects efficiency. Moreover, the distribution cabinet does not have a buffer device. During the hoisting operation, the distribution cabinet often comes into rigid contact with the ground, and the impact may cause damage to the internal structure. Utility Model Content

[0005] The purpose of the utility model is to provide a hoisting mechanism for a power distribution cabinet to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A hanging mechanism for a power distribution cabinet comprises a power distribution cabinet body, a plurality of mounting blocks are fixedly connected to the side walls of the power distribution cabinet body, a plurality of guide rods are fixedly connected to the bottom of the mounting blocks, a placement block is fixedly connected to the bottom end of the guide rod, a slider is inserted into the guide rod, a plurality of movable rods are fixedly connected to the bottom of the power distribution cabinet body, a buffer spring is fixedly connected to the bottom of the movable rod, the buffer spring is fixedly connected to a fixing seat, and a base is fixedly connected to the bottom of the fixing seat.

[0008] Preferably, a movable door is movably connected to the side wall of the power distribution cabinet body, and a handle is fixedly connected to the side wall of the movable door.

[0009] Preferably, a buffer pad is fixedly connected to the top of the fixing seat, and the base is made of rubber buffer material.

[0010] Preferably, a through hole is provided on the side wall of the slider, a pin is movably connected inside the through hole, and a fixing hole is provided on the side wall of the power distribution cabinet body.

[0011] Preferably, a mounting hole is fixedly connected to the top of the sliding block, and a lifting ring is connected inside the mounting hole.

[0012] Preferably, a limiting block is fixedly connected to the bottom of the movable rod, and the limiting block is movably connected to an inner groove of the fixing seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. This lifting mechanism for a power distribution cabinet is arranged through a mounting block, a guide rod, etc. When in use, the slider is stationary inside the placement block. By lowering the height of the slider, it is convenient for workers to fix the lifting ring and the lifting rope of the crane, making it easier to lift the power distribution cabinet. At the same time, the horizontal displacement of the slider is limited by the guide rod, which effectively prevents the slider from detaching and deflecting, thereby causing the distribution box to fall and damage the distribution box, or even injuring on-site personnel.

[0015] 2. This kind of lifting mechanism for the distribution cabinet is arranged by means of a buffer spring, a movable rod, etc. The movable rod is driven downward by the distribution cabinet body to deform the buffer spring, and the deformation of the buffer spring produces a buffer to avoid large amplitude vibration inside the distribution cabinet structure. At the same time, the buffer spring avoids the rigid contact between the distribution cabinet body and the ground during the lifting work, thereby increasing the service life of the distribution cabinet.
