[0035] The locking assembly includes a rotating column 16, which is coaxially fixedly connected to the transmission rod 15. The rotating column 16 is provided with a plurality of thread grooves 17 uniformly distributed along its circumferential direction.

When the rotating shaft 33 rotates, the movable plate 20 can move between the two annular grooves 18 by sliding, the threaded groove 17 and the push plate 22. Then, when the lifting frame 5 descends, the two movable plates 20 in the protective shell 6 move away from each other, and when the lifting frame 5 rises, the two movable plates 20 move relative to each other.

[0037] An inverted T-shaped fixing frame 25 is provided on the upper side of the driving plate 23, and the fixing frame 25 is fixedly connected to the lifting frame 5.

[0038] As shown in the figure, the fixed frame 25, the moving rod 26, the driving pin 27, the ratchet bar 28, the return spring and the ratchet block 29 are arranged so that when the lifting frame 5 is lowered, the two moving plates 20 move in opposite directions, so that the two ratchet blocks 29 are driven to disengage from the meshing with the ratchet bar 28 through the action of the driving groove 24 and the driving pin 27, so as to ensure that the lifting frame 5 can be normally lowered. When the lifting frame 5 is raised, the two moving plates 20 move relative to each other, so that the two ratchet blocks 29 are driven to mesh with the ratchet bar 28 through the action of the driving groove 24 and the driving pin 27, so as to ensure that the lifting will not fall rapidly when driving the electromechanical equipment to rise. There is a gap between the teeth when the spur gear 34 is meshed with the spur rack 4, and this gap is enough for the sliding pin 21 to enter from one annular groove 18 to another annular groove 18 through the thread groove 17. The lifting assembly includes a bevel gear 30, which is coaxially fixedly connected to the transmission shaft, a helical gear 31 is meshed with the rear side of the bevel gear 30, and connecting rods 32 are coaxially provided on the front and rear sides of the helical gear 31, the helical gear 31 is fixedly connected to the connecting rod 32 on the rear side, and the opposite sides of the two connecting rods 32 are fixedly connected with cooperative gears, the left and right sides of the protective shell 6 are respectively rotatably connected to the rotating shaft 33, and the front and rear sides of the rotating shaft 33 are respectively fixed with driven gears that can mesh with the cooperative gears on the corresponding sides, the connecting rod 32 is coaxially sleeved with the moving rod 26 on the corresponding side, the connecting rod 32 is rotatably connected to the lifting frame 5, and the other end of the connecting rod 32 is fixedly connected with a spur gear 34, which meshes with the spur rack 4 on the corresponding side.

[0039] As shown in the figure, the bevel gear 30, the helical gear 31, the connecting rod 32, the cooperating gear, the rotating shaft 33, the driven gear, the spur gear 34 and the spur rack 4 are arranged so that the rotation of the bevel gear 30 can be used to drive the connecting rod 32 on the rear side to rotate via the helical gear 31, and at the same time, the connecting rod 32 on the front side and the connecting rod 32 on the rear side can be driven to rotate synchronously through the cooperating gear and the driven gear, thereby ensuring that the front and rear spur gears 34 can be raised and lowered synchronously.

[0040] The support assembly includes a spur gear 35, which is rotatably connected to the frame 1. Push-pull rods 36 are slidably connected to the left and right sides of the frame 1. A downward pressing groove 37 is provided on the upper side of the support frame 7. The opposite sides of the two push-pull rods 36 are respectively fixedly connected to downward pressing pins located in the downward pressing groove 37 on the corresponding side. The opposite ends of the two push-pull rods 36 are respectively provided with movable grooves 38. The front and rear sides of the spur gear 35 are respectively fixedly connected to movable pins 39 located in the movable grooves 38 on the corresponding side. The spur gear 35 A ratchet gear 40 is coaxially fixedly connected to one side, and two front-to-back symmetrical support plates 41 are provided on the left side of the spur gear 35. The right side of the outer support plate 41 is slidably connected with an arc-shaped ratchet plate 43 that can mesh with the ratchet gear 40 through two compression springs. One-way grooves 42 are respectively provided at the opposite ends of the two support plates 41. A tooth plate 43 that can mesh with the spur gear 35 is slidably connected between the two support plates 41. One-way pins 44 that can be inserted into the corresponding side one-way grooves 42 are slidably connected to the tooth plate 43 on both sides through three compression springs.

[0041] As shown in the figure, the spur gear 35, the push-pull rod 36, the movable groove 38, the movable pin 39, the ratchet gear 40, the support plate 41, the second compression spring and the ratchet plate 43 can utilize the rotation of the spur gear 35 to drive the push-pull rod 36 to move back and forth left and right through the movable groove 38 and the movable pin 39, thereby driving the support frame 7 to descend, and the frame 1 can be supported to improve the overall stability and avoid the problem of movement during the lifting process. At the same time, the ratchet gear 40 and the ratchet plate 43 can prevent the tooth plate 43 from being out of mesh with the spur gear 35. In order to solve the problem that the support frame 7 is retracted due to the current rotation, a one-way groove 42, a tooth plate 43, a compression spring and a one-way pin 44 are provided. The one-way groove 42 can be used to cause the tooth plate 43 to mesh with the spur gear 35 during the process of moving downward, so that it can drive the spur gear 35 to rotate 180 degrees. When the tooth plate 43 is disengaged from the spur gear 35 during the upward process, the tooth plate 43 can be returned to its original position and mesh with the spur gear 35 again when it rises to the highest position, so that the spur gear 35 can be driven to rotate 180 degrees again during the descent process.

[0042] The front and rear sides of the upper end of the frame 1 are respectively slidably connected with a balancing frame 45, and the balancing frame 45 is slidably connected to the gear plate 43 on the corresponding side.

[0043] As shown in the figure, the balance frame 45 can be used to prevent the tooth plate 43 from being skewed, so that the tooth plate 43 is kept in a vertical state.

[0044] A lower pressing plate 46 is disposed above the vehicle frame 1 , the upper end of the lower pressing plate 46 can contact the lower end of the protective shell 6 , and the front and rear sides of the lower pressing plate 46 are respectively fixedly connected to the toothed plates 43 on the corresponding sides.

[0045] As shown in the figure, the lower pressure plate 46 is set up so that the tooth plate 43 can be driven to descend by the lower pressure plate 46, thereby causing the support frame 7 to descend to support the frame 1, so that the moving wheels are no longer in contact with the ground. At the same time, when the lifting and installation of the electromechanical equipment is completed, the tooth plates 43 on the front and rear sides can be manually lifted by the lower pressure plate 46, and the support frame 7 can be retracted by pressing down on the protective shell 6 again, and then it can be moved.

[0046] A fence 47 is fixedly connected to the upper end of the lifting platform 2 .

[0047] As shown in the figure, the provision of the enclosure 47 can prevent the electromechanical equipment from becoming unstable during the lifting process and causing the problem of tilting and falling, thereby providing protection for the staff.

[0048] When the present invention is in use, the vehicle frame 1 is used to move the device as a whole to a suitable position, and then the driving motor 14 is started. When it is just started, the transmission rod 15 drives the rotating column 16 to rotate, and the rotating column 16 drives the moving plate 20 to move under the action of the thread groove 17 and the push plate 22, and the two moving plates 20 move in opposite directions. Then, at this time, the ratchet blocks 29 on the front and rear sides are driven to disengage from the meshing with the ratchet bar 28 through the action of the driving groove 24 and the driving pin 27, and at the same time, the bevel gear 30 drives the connecting rod 32 to rotate through the helical gear 31, and the lifting frame 5 can be driven to descend through the action of the spur gear 34 and the spur rack 4. When it descends to the lower end limit position, the protective shell 6 contacts the lower pressure rod, and the spur gear 35 can be driven to rotate through the tooth plate 43. The spur gear 35 can drive the push-pull rods 36 on both sides to move in opposite directions, so that the support frame 7 is lowered and contacts the ground; Then the electromechanical device can be placed on the lifting frame 5, and then the driving motor 14 is reversed, and the two moving plates 20 move relative to each other under the action of the sliding pins 21 and the threaded grooves 17 on their corresponding sides, so that the two connecting rods 32 move away from each other, causing the ratchet block 29 to mesh with the ratchet bar 28 again, and then the lifting frame 5 drives the electromechanical device to rise under the action of the spur gear 34 and the spur rack 4 until the upper end surface of the lifting frame 5 is flush with the upper end surface of the lifting platform 2; Then, the hollow motor 10 is started to drive the lifting platform 2 to the position where the electromechanical equipment needs to be lifted. After the lifting is completed, the lifting platform 2 is lowered to the lower limit position, and the electromechanical equipment can continue to be lifted; When all the lifting is completed, the staff can lift the lower pressure rod to the upper limit position, so that the tooth plate 43 is engaged with the spur gear 35 again, and then use the protective shell 6 to drive the lower pressure plate 46 to descend again, so that the support frame 7 can be retracted, and then the device can be moved to the appropriate position and continue to lift.

[0049] In the present invention, the hollow motor 10 and the driving motor 14 are both prior art and will not be described in detail herein.

[0050] The specific embodiments described herein are merely examples of the spirit of the present invention.
