The fastening bolt 17 not only has a strong fastening force, but also its detachability makes the replacement of the corner rubber frame block 16 convenient and quick.

[0030] Reference Figures 1 to 6 An internal thread groove 20 is provided at the other end of the top of the supporting movable frame 2, and the internal thread groove 20 is adapted to the bolt 4, and the other end of the bolt 4 penetrates the load-bearing plate 3 and is threadedly connected to the supporting movable frame 2.

[0031] Using the above solution: the operator passes the bolt 4 through the load-bearing plate 3, and then screws it into the internal thread groove 20 on the top of the supporting mobile frame 2, and by rotating the bolt 4, it is tightly engaged with the internal thread groove 20, thereby achieving a firm connection between the supporting mobile frame 2 and the load-bearing plate 3.

[0032] Reference Figures 1 to 6 There are two groups of connecting crossbeam plates 1, and there are four groups of supporting mobile frames 2, load-bearing plates 3, inclined street blocks 5, electric telescopic rods 7, threaded fasteners 8, adjusting slide rods 9 and positioning fastening mechanisms 10.

[0035] By adopting the above scheme, the operator can push the entire device to move by controlling the push rod handle 11, and control the stopping position of the device by operating the braking function of the universal brake wheel 12, so that the operator can easily and accurately control the movement state of the device, thereby improving the efficiency and safety of the installation work.

[0036] The working principle of the utility model is as follows: when in use, by adjusting the connection relationship between the slide bar 9 and the inclined street block 5, the two ends of the adjusting slide bar 9 are respectively connected to the two groups of inclined street blocks 5, and then the threaded fasteners 8 are used to fix the adjusting slide bar 9 and the inclined street block 5, and the load-bearing plate 3 is placed on the top of the supporting mobile frame 2, and then the two are fixed with bolts, so that the purpose of easy disassembly and installation can be achieved, which greatly improves the convenience and flexibility of the positioning device, and also facilitates the subsequent maintenance and replacement of parts; by pushing The push rod handle 11 moves the two sets of supporting moving frames 2 closer to the car, and then the two sets of electric telescopic rods 7 are respectively started to move the two sets of L-shaped corner lock blocks 14 toward the corners on both sides of the car, and the corner rubber frame blocks 16 inside the L-shaped corner lock blocks 14 are tightly attached to the corners of the car. The corner rubber frame blocks 16 have a certain elasticity and buffering effect, which can ensure that the corners of the car will not be damaged during the process of tightly attaching, and the tightness of the corner rubber frame blocks 16 can also improve the stability of positioning, preventing the car from shifting or shaking during the installation process. The pressure fixing block 15 on the outer side of the L-shaped corner locking block 14 moves on the adjusting slide bar 9 during the movement, so that stable guidance and support can be maintained to ensure that it can smoothly reach the predetermined position. The other two groups of supporting moving frames 2 are operated in the same way, so that the four corners of the car can be quickly positioned, which not only improves the flexibility of positioning, but also reduces the difficulty of adapting to cars of different sizes; the corner rubber frame block 16 is a component that directly contacts the corners of the elevator car, so it is likely to be worn due to friction or impact during use, and long-term use and environmental factors may also cause the corner rubber frame block 16 to age or be damaged, and the corner rubber frame block 16 is connected to the L-shaped corner locking block 14 by a fastening bolt 17, so that it can be easily replaced, which not only simplifies the replacement process, improves work efficiency, but also reduces maintenance costs. In addition, since the corner rubber frame block 16 is a component that can be replaced separately, there is no need to carry out large-scale maintenance or replacement of the entire positioning device, which further extends the service life of the device.

[0037] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
