Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a base structure of an elevator. Background Art

[0002] A lift is a multifunctional lifting mechanical equipment, which can be divided into fixed and mobile types, guide rail type, curved arm type, scissors type, chain type, loading and unloading platform, etc., and is often used for rescue and decoration.

[0003] In the prior art, such as the Chinese patent application No. 201721596526.6, a construction site elevator lifting mechanism connecting base is provided with four square fixing columns on the top, so it has strong stability during operation, and positioning holes and fixing holes are provided on the top of the connecting seat, so it is convenient to install and connect, and easy to position, and a square baffle is provided on the front side of the connecting seat, so the connecting seat is not prone to wear and collision, and is not easy to be damaged. The above device has the following shortcomings: 1. The base can only fix the lifting mechanism of specified specifications, and when the specified lifting mechanism is damaged, other lifting mechanisms cannot be used to replace it, which has high limitations; 2. It does not have an alarm function when in use. If someone accidentally approaches it when it is working, it cannot play a warning function, which increases the safety risk; 3. People cannot easily know whether the base is in a horizontal state. If the tilt angle of the base is too large, it is very likely to cause the goods to fall during the lifting process, which increases the safety risk.

[0004] In the prior art, such as the Chinese patent CN 211110751 U, a crawler lift base structure includes a bearing plate, a connecting threaded hole is provided at the corner of the top surface of the bearing plate, and a No. 1 screw is connected in the connecting threaded hole by threading, a fixing seat is welded on one side of the top of the bearing plate, and a warning light is installed on the top of the fixing seat by bolts, fixing blocks are welded on both ends of the top of the bearing plate, and a No. 2 screw is installed on one side of the fixing block by threading, a fixing plate is welded on one end of the No. 2 screw, and fixing threaded holes are provided on both sides of the top of the fixing plate, and a level is installed on one side of the bearing plate by bolts. The utility model provides a crawler lift base structure with simple structure and convenient use, which is suitable for being widely promoted and used. However, the patent still has the following problems.

[0005] In the above patent, although a fixed plate is provided with fixed threaded holes on both sides of the top surface of the fixed plate for installing lifts with different installation requirements, the device can only control the movement of the No. 2 screw to control the movement of the two fixed plates, thereby controlling the distance between the two sets of fixed threaded holes. However, the distance between the fixed threaded holes on the top of each fixed plate is fixed. Therefore, if other lifts are installed, their installation positions may be slightly different from the positions of the fixed threaded holes, thereby affecting the installation. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that the distance between the fixing threaded holes on the top of each fixing plate is fixed. Therefore, when other elevators are installed, their installation positions may be slightly different from the positions of the fixing threaded holes, thereby affecting the installation. A lift base structure is proposed.

[0007] The two cams have the second end in one piece and the second end in one piece, and the two cams have the second end in one piece, and the two cams have the second end in one piece.

[0008] Preferably, two connection seats are fixedly mounted on the four outer side walls of the supporting platform, and a first through hole is formed through the top of the connection seat.

[0009] Preferably, an extension plate is slidably mounted inside the connection seat, and two second through holes are formed through the top of the extension plate.

[0010] Preferably, first threaded holes are formed through the four corners of the top of the supporting platform and the top of the extension plate, a first threaded rod is threadedly connected inside the first threaded hole, a first handle is fixedly installed on the top of the first threaded rod, and a base column is fixedly installed on the bottom of the first threaded rod.

[0013] Preferably, the third threaded rod is provided with two sections of threads with opposite textures, and the third threaded rod is connected to the two clamping plates respectively through the two sections of threads with opposite textures.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, during installation, the staff turns the second handle, the second threaded rod turns, and the second threaded rod moves along the second threaded hole, thereby pushing the movable plate to move, and then the staff pulls the sliding seat, and the sliding seat moves along the fixed rod. When the second through hole is adjusted to a suitable position, the staff turns the third handle, and the third threaded rod turns, thereby driving the two clamps to approach each other until they contact the fixed rod. The pressure of the clamps on the fixed rod increases the friction between the clamps and the fixed rod, so that the sliding seat can be fixed, and the adjustment can be completed in this way, which is convenient for fixing lifts of different specifications.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a lift base structure, including a bearing platform 1, two fixing plates 11 are fixedly installed on the top of the bearing platform 1, the outer walls of the two fixing plates 11 are penetrated with second threaded holes 12, the insides of the two second threaded holes 12 are threadedly connected with second threaded rods 13, the two second threaded rods 13 are fixedly installed with second handles 14 on the opposite sides, the two second threaded rods 13 are movably connected with a moving plate 15 on the opposite sides, and the moving plate 15 is fixedly installed with a limiting rod 16 on one end close to the second threaded rod 13, and the limiting rod 16 is away from the moving plate 15. One end of the movable plate 15 is slidably plugged into the fixed plate 11, and support plates 17 are fixedly installed on both sides of the movable plate 15, and a fixed rod 18 is fixedly installed between the two support plates 17. A plurality of sliding seats 19 are slidably installed on the outer wall of the fixed rod 18, and a sliding groove 21 is provided inside the plurality of sliding seats 19. A third threaded rod 22 is rotatably installed inside the sliding groove 21, and the top of the third threaded rod 22 passes through the sliding seat 19 and is fixedly installed with a third handle 23. The outer wall of the third threaded rod 22 is threadedly connected to two clamping plates 24, and a third threaded hole 20 is provided on the top of the sliding seat 19.

[0025] The effect achieved by the entire embodiment 1 is that during installation, the staff rotates the second handle 14, the second threaded rod 13 rotates, and the second threaded rod 13 moves along the second threaded hole 12, thereby pushing the movable plate 15 to move, and then the staff pulls the sliding seat 19, and the sliding seat 19 moves along the fixed rod 18. When the second through hole 25 is adjusted to a suitable position, the staff rotates the third handle 23, and the third threaded rod 22 rotates, thereby driving the two clamps 24 to approach each other until they contact the fixed rod 18. The pressure of the clamp 24 on the fixed rod 18 increases the friction between the clamp 24 and the fixed rod 18, so that the sliding seat 19 can be fixed, and the adjustment can be completed in this way, which is convenient for fixing lifts of different specifications.

[0026] Embodiment 2, as Figure 1-Figure 4 As shown, further, two connecting seats 4 are fixedly mounted on the four outer side walls of the supporting platform 1 , and a first through hole 5 is formed through the top of the connecting seat 4 .

[0027] Furthermore, an extension plate 6 is slidably installed inside the connection seat 4 , and two second through holes 25 are formed through the top of the extension plate 6 .

[0028] Furthermore, first threaded holes 7 are formed through the four corners of the top of the support platform 1 and the top of the extension plate 6, and first threaded rods 8 are threadedly connected inside the first threaded holes 7. A first handle 9 is fixedly installed on the top of the first threaded rod 8, and a base column 10 is fixedly installed on the bottom of the first threaded rod 8.

[0029] Furthermore, a level 3 is fixedly mounted on the outer wall of the support platform 1 to facilitate checking whether the support platform 1 is in a horizontal state.

[0030] Furthermore, a crawler 2 is provided at the bottom of the supporting platform 1 to facilitate the movement of the device.

[0031] Furthermore, the third threaded rod 22 is provided with two sections of threads with opposite textures, and the third threaded rod 22 is connected to the two clamping plates 24 respectively through the two sections of threads with opposite textures.

[0032] The effect achieved by the entire embodiment 2 is that, if the elevator uses an extension component, the staff will insert the extension plate 6 into the connecting seat 4 in the corresponding direction according to the extension component, and then use bolts to pass through the first through hole 5 and the second through hole 25 to fix the extension plate 6, and then turn the first handle 9 and the first threaded rod 8 until the base column 10 contacts the ground, so as to provide support and prevent one side of the elevator from being too heavy when the elevator uses the extension component, thereby causing unstable support.

[0033] Working principle: During installation, the staff turns the second handle 14, the second threaded rod 13 turns, and the second threaded rod 13 moves along the second threaded hole 12, thereby pushing the movable plate 15 to move. Then the staff pulls the sliding seat 19, and the sliding seat 19 moves along the fixed rod 18. When the second through hole 25 is adjusted to a suitable position, the staff turns the third handle 23, and the third threaded rod 22 turns, thereby driving the two splints 24 to approach each other until they contact the fixed rod 18. The pressure of the splint 24 on the fixed rod 18 increases the friction between the splint 24 and the fixed rod 18, so that the sliding seat 19 can be fixed, and the adjustment can be completed in this way, which is convenient for fixing lifts of different specifications. If the elevator uses an extension component, the staff will insert the extension plate 6 into the connecting seat 4 in the corresponding direction according to the extension component, and then use bolts to pass through the first through hole 5 and the second through hole 25 to fix the extension plate 6, and then turn the first handle 9, and the first threaded rod 8 until the bottom column 10 contacts the ground, so as to provide support to prevent the elevator from being too heavy on one side when the elevator uses the extension component, resulting in unstable support. The staff can know whether the support platform 1 is in a horizontal state through the level 3. If it is not in a horizontal state, the staff can rotate the first threaded rod 8 through the first handle 9 to adjust the angle of the support platform 1, so that the support platform 1 is in a horizontal state, preventing the goods from falling during the lifting process and improving safety.
