[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a movable support platform for elevator maintenance. Figure 1 A movable support platform for elevator maintenance includes a base plate 1, a plurality of support columns 2 and a walking mechanism 3. The base plate 1 is horizontally arranged, the support columns 2 are mounted on the upper end surface of the base plate 1, and the walking mechanism 3 is mounted on the lower end surface of the base plate 1.

[0033] Reference Figure 1 and Figure 2 The support column 2 includes a first column 21, a second column 22 and an adjusting member. The first column 21 and the second column 22 both extend vertically, the lower end of the first column 21 is fixed to the upper end surface of the bottom plate 1, and the second column 22 is coaxially penetrated and slidably connected to the upper end of the first column 21. The adjusting member is configured as a locking bolt 23, which penetrates the first column 21 and the second column 22 at the same time, and the second column 22 is provided with a plurality of vertically distributed adjusting holes 221, so that the locking bolt 23 can penetrate into the adjusting hole 221.

[0034] When in use, the supporting platform is placed under the car as a whole, so that the tops of the multiple supporting columns 2 are supported on the lower surface of the suspended car at the same time, so as to achieve the purpose of positioning the car, so that the maintenance personnel can inspect the bottom of the car. In addition, during the inspection of the bottom of the elevator, the possibility of accidental falling of the car can be reduced, thereby improving the safety of the inspection process.

[0035] In addition, in the process of supporting the car, the installation height of the second column 22 can be adjusted by the locking bolt 23 to adapt to different support heights, thereby increasing the application range of the support platform and improving the use effect.

[0036] The walking mechanism 3 can improve the convenience of the overall support platform when moving on the road surface, thereby further improving the overall use effect of the support platform.

[0037] Reference Figure 2In this embodiment, two locking bolts 23 are provided on the same support column 2. In this case, the locking bolt 23 is provided with a connecting strip 231, and the connecting strip 231 simultaneously connects the two locking bolts 23. During installation, the two locking bolts 23 can be simultaneously passed through the adjustment holes 221 on the first column 21 and the second column 22 by holding the connecting strip 231. In the process of supporting the car, the load bearing capacity of the connection part between the first column 21 and the second column 22 can be improved, and the locking effect of the second column 22 can be improved.

[0038] In other embodiments, the adjusting member may also be configured as a nut, which is threadedly connected to the second cylinder 22 and rotatably connected to the first cylinder 21. Of course, the second cylinder 22 may also be directly coaxially penetrated and threadedly connected to the upper end of the first cylinder 21.

[0039] Reference Figure 1 and Figure 3 The walking mechanism 3 includes a plurality of walking wheels 31 and a plurality of supporting components 32. The walking wheels 31 are installed on the lower surface of the base plate 1, so that when the supporting platform as a whole moves on the road surface, the walking wheels 31 can abut against the ground, thereby improving the convenience of the supporting platform as a whole during movement.

[0040] Reference Figure 3 The supporting component 32 includes a connecting tube 321, a supporting foot 322 and an adjusting nut 323. The connecting tube 321 extends vertically and is fixed to the lower surface of the bottom plate 1. The supporting foot 322 is coaxially arranged and slidably connected to the lower end of the connecting tube 321. A vertically extending limiting groove 324 is provided on the side wall of the supporting foot 322, and the connecting tube 321 is clamped in the limiting groove 324. The adjusting nut 323 is sleeved and threadedly connected to the supporting foot 322, and the adjusting nut 323 is rotatably connected to the connecting tube 321.

[0041] When the entire support platform is located below the car and before the car needs to be supported, the adjusting nut 323 can be rotated first to make the support foot 322 slide downward and abut against the floor in the elevator shaft. This allows multiple support components 32 to support the bottom plate 1 at the same time, so that the support column 2 is supported at the bottom of the car and during subsequent maintenance, the pressure on the running wheel 31 can be reduced, thereby reducing the possibility of damage to the running wheel 31 and increasing the service life of the running wheel 31. At the same time, the overall stability of the support platform during use is made more difficult to shake.

[0042] In addition, the connecting tube 321 is clamped in the limiting groove 324 to limit the rotation of the supporting leg 322, so that the stability of the sliding of the supporting leg 322 is better during the rotation of the adjusting nut 323.

[0043] Reference Figure 4The bottom plate 1 is provided with a guardrail 4, which is located above the bottom plate 1 and extends along the edge of the bottom plate 1. The guardrail 4 is penetrated with a plurality of vertically extending connecting bolts 41, and the side wall of the bottom plate 1 is provided with a plurality of embedded grooves 11, and clamping nuts 42 are clamped in the embedded grooves 11. The connecting bolts 41 penetrate into the embedded grooves 11 from the upper surface of the bottom plate 1 and are threadedly connected to the clamping nuts 42.

[0044] In addition, the guardrail 4 is fixed with a plurality of reinforcing pins 43 , which are plugged into the bottom plate 1 .

[0045] During use, the maintenance personnel can lie flat on the upper end of the bottom plate 1 and face the bottom of the car for maintenance. During the maintenance process, the guardrail 4 can protect the maintenance tools used, reduce the possibility of the maintenance tools falling from the edge of the bottom plate 1, and further improve the convenience of the maintenance process.

[0046] When installing the guardrail 4, you only need to first insert the clamping nut 42 into the embedding groove 11, then place the guardrail 4 against the upper end surface of the base plate 1, and then pass the connecting bolt 41 through the guardrail 4 and the base plate 1 in turn, and then thread it into the clamping nut 42, so that the installation process of the guardrail 4 is relatively convenient.

[0047] When the guardrail 4 abuts against the base plate 1 , the reinforcing pin 43 is inserted into the base plate 1 , thereby improving the ability of the guardrail 4 to withstand lateral loads and reducing the possibility of the guardrail 4 tipping over during use.

[0048] In other embodiments, the running wheel 31 can also be set as a telescopic structure, so that the running wheel 31 is slidably set at the bottom of the base plate 1. In use, the running wheel 31 can be stored so that the base plate 1 itself is in contact with the ground, thereby reducing the possibility of damage to the running wheel 31 due to a large load.

[0049] The implementation principle of the movable support platform for elevator maintenance in the embodiment of the present application is as follows: when in use, the entire support platform only needs to be placed under the car, so that the tops of multiple support columns 2 are simultaneously supported on the lower surface of the suspended car, thereby achieving the purpose of positioning the car and facilitating maintenance personnel to inspect the bottom of the car. In addition, during the maintenance process, the possibility of accidental falling of the car can be reduced, thereby improving safety during the maintenance process. The walking wheels 31 can improve the convenience of the entire support platform when moving on the road surface, further improving the overall use effect of the support platform.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
