Description

Technical Field

[0001] This utility model relates to the field of meter box installation technology, specifically to a meter box installation lifting frame. Background Technology

[0002] The main function of an electric meter box is to store electric meters, and it is also used to manage and protect electrical equipment. Electric meter boxes are widely used in various places, including homes, shopping malls, and office buildings. Existing electric meter boxes require a lifting frame to move the meter box up and down during installation.

[0003] However, some existing lifting platforms require hooks and steel cables to move the meter box up and down when put into use. Due to the influence of wind in the external environment, the meter box may sway, which may cause the meter box to accidentally detach from the hook and fall to the ground, resulting in damage to the meter box. At the same time, most lifting platforms require workers to climb to a high position to reach the meter box and carry out installation work. Working at height is inherently dangerous, and workers also need to frequently change tools from their tool bags, posing safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a meter box installation lifting frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a meter box mounting lifting frame, comprising a base and a support frame bolted to the top of the base, and further comprising:

[0006] A lifting assembly is installed on one side of the support frame. A guide block is slidably connected to one side of the support frame. A fixed shell is bolted to the bottom of the guide block. A moving mechanism is provided in the inner cavity of the fixed shell. A protective plate is slidably connected to the other side of the fixed shell.

[0007] A connecting block is bolted to the surface of the support frame. A rotating rod is rotatably connected to one side of the connecting block, and a placement plate is fixedly connected to the other end of the rotating rod. A limit mechanism is provided on one side of the placement plate.

[0008] Preferably, the moving mechanism includes a hand dial disposed on one side of the fixed shell, a bidirectional threaded rod fixedly connected to one side of the hand dial, a sleeve threadedly connected to the surface of the bidirectional threaded rod, the surface of the sleeve being slidably connected to the inner cavity of the fixed shell, and one side of the sleeve being bolted to one side of the protective plate.

[0011] Preferably, the guide block has a T-shaped cross-section, and the protective plate is located at the bottom of the lifting assembly.

[0012] Preferably, a bearing seat is fixedly connected to the inner cavity of the fixed shell, and one side of the bearing seat is rotatably connected to one end of the bidirectional threaded rod.

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

[0014] This invention, through the cooperation of guide blocks, a fixed shell, and a moving mechanism, enables the protective plates on both sides to move simultaneously in opposite directions.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, a meter box mounting lifting frame includes a base 1, a support frame 2 bolted to the top of the base 1, a lifting assembly 3 on one side of the support frame 2, the lifting assembly 3 consisting of a hook and a steel wire rope, which, in cooperation with the support frame 2 and the lifting assembly 3, can move the meter box up and down. A control panel 4 is provided on one side of the base 1, which works in conjunction with the lifting assembly 3, enabling the lifting assembly 3 to operate. A guide block 5 is slidably connected to one side of the support frame 2, and the other side of the guide block 5 is bolted to one side of the lifting assembly 3, enabling the guide block 5 to move up and down on one side of the base 1 under the action of the lifting assembly 3. A fixed shell 6 is bolted to the bottom of the guide block 5, and a moving mechanism 7 is provided inside the fixed shell 6. A protective plate 9 is slidably connected to the other side of the fixed shell 6. The guide block 5 has a T-shaped cross-section, and the protective plate 9 is located at the bottom of the lifting assembly 3. In cooperation with the fixed shell 6 and the moving mechanism 7, it can... The protective plates 9 on both sides can move simultaneously in opposite directions, allowing them to clamp the meter box. This effectively prevents the meter box from shaking and detaching when the lifting assembly 3 moves, increasing the stability of the lifting assembly 3 during operation and thus improving the practicality of the lifting frame. A connecting block 10 is bolted to the surface of the support frame 2. A rotating rod 11 is rotatably connected to one side of the connecting block 10, and a placement tray 12 is fixedly connected to the other end of the rotating rod 11. With the cooperation of the connecting block 10 and the rotating rod 11, the placement tray 12 can rotate on one side of the base 1, allowing the placement tray 12 to place and store tools used by the staff, making it convenient for staff to retrieve the tools and increasing the safety of the staff. This improves the effectiveness of the lifting frame. A limiting mechanism 13 is provided on one side of the placement tray 12, which can limit the placement tray 12 and allow it to be stored when not in use.

[0022] The moving mechanism 7 includes a hand-operated turntable 71 located on one side of the fixed housing 6. A bidirectional threaded rod 72 is fixedly connected to one side of the hand-operated turntable 71. A sleeve 73 is threadedly connected to the surface of the bidirectional threaded rod 72. The surface of the sleeve 73 is slidably connected to the inner cavity of the fixed housing 6. One side of the sleeve 73 is bolted to one side of the protective plate 9. With the cooperation of the hand-operated turntable 71 and the bidirectional threaded rod 72, the sleeve 73 can drive the protective plates 9 on both sides to move in opposite directions simultaneously, so that the protective plates 9 clamp and protect the meter box. This effectively reduces the shaking of the meter box when the lifting assembly 3 moves, thereby reducing the possibility of the meter box detaching from the surface of the lifting assembly 3 and improving the stability of the lifting frame during use. A bearing seat 8 is fixedly connected to the inner cavity of the fixed housing 6. One side of the bearing seat 8 is rotatably connected to one end of the bidirectional threaded rod 72. Under the action of the bearing seat 8, the position of the bidirectional threaded rod 72 is effectively prevented from shifting during operation, increasing the stability of the moving mechanism 7 and thus improving the stability of the lifting frame.

[0023] The limiting mechanism 13 includes a torsion spring 131. One end of the torsion spring 131 is fixedly connected to one side of the connecting block 10, and the other end of the torsion spring 131 is fixedly connected to the surface of the placement tray 12. A rotating shaft 132 is rotatably connected to the surface of the support frame 2. A limiting plate 133 is fixedly connected to the other end of the rotating shaft 132. The surface of the limiting plate 133 is slidably connected to the bottom of the placement tray 12. Under the action of the rotating rod 11, the placement tray 12 can rotate on one side of the base 1, and the limiting plate 133 can rotate on one side of the rotating shaft 132, allowing the limiting plate 133 to rotate to the surface of the placement tray 12. Under the action of the rebound force of the torsion spring 131, the placement tray 12 can be limited to one side of the limiting plate 133, allowing the placement tray 12 to be stored when idle, thereby reducing the accumulation of dust on one side of the placement tray 12.

[0024] Working principle: When the operator needs to move the meter box to the top, the operator moves the hook of the lifting assembly 3 downward through the control panel 4. Then, the operator connects the meter box to the lifting assembly 3. At the same time, under the action of the hand dial 71, the double-threaded rod 72 can rotate on one side of the bearing seat 8. The double-threaded rod 72 can cause the sleeve 73 to drive the protective plates 9 on both sides to move in opposite directions at the same time, so that one side of the protective plate 9 can contact the surface of the meter box. Then, the operator moves the lifting assembly 3 to move the meter box upward through the control panel 4. At the same time, the lifting assembly 3 moves the fixed shell 6 to move the protective plate 9 upward through the guide block 5, reducing the shaking of the meter box during movement. When the operator needs to install the meter box with tools, the operator rotates the limiting plate 133 on one side of the rotating shaft 132, so that the limiting plate 133 and the placement plate 12 can be interleaved. Under the action of the torsion spring 131, the rotating rod 11 can drive the placement plate 12 back to its original position. The operator can then place the tools to be used on the top of the placement plate 12.
