[0001] The utility model relates to the technical field of elevator installation, in particular to an elevator installation support device. Background Art

[0002] The elevator door is a very important part of the elevator. There are two doors. The one that can be seen from the outside of the elevator and is fixed on each floor is called the hall door, and the one that can be seen from the inside and is fixed to the car and moves with the car is called the car door. The installation of the elevator door is an important part of the installation and commissioning of the elevator. It is difficult and requires special support tools to temporarily fix the elevator door to prevent the elevator door from falling.

[0003] In the prior art with announcement number CN220412779U, a support device for elevator installation is proposed, which uses a rotating wheel to move the bottom plate and the elevator door to a suitable position, thereby achieving the support work of the elevator door on the ground outside the elevator entrance, providing convenience for the installation process of the elevator door.

[0004] However, the elevator installation support device proposed in the above-mentioned prior art cannot properly position the roller after pushing the device to a suitable position through the roller, which may cause the roller to move and affect the installation of the elevator door. Therefore, the present application proposes an elevator installation support device to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide an elevator installation support device to solve the problem that after the device is pushed to a suitable position by a roller, the roller cannot be well positioned, resulting in the roller possibly moving and thus affecting the installation of the elevator door.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The lifting of the ...

[0008] As a further solution of the utility model: a rubber pad is fixedly installed on one side of each of the second extrusion plates.

[0009] As a further solution of the utility model: a motor is fixedly installed on the top of the mounting frame, a screw rod is fixedly installed on the output shaft of the motor, a first guide rod is fixedly installed inside the mounting frame, the first guide rod and the screw rod both pass through the mounting block, the screw rod is threadedly connected to the mounting block, and the first guide rod is slidably connected to the mounting block.

[0010] As a further solution of the utility model: sliding blocks are fixedly installed on both sides of the mounting block, the sliding blocks pass through the mounting frame and are slidably connected to the mounting frame, and the mounting frame is provided with sliding grooves for slidably connecting to the sliding blocks.

[0012] As a further solution of the utility model: a counterweight block is fixedly installed on one side of the top of the bottom plate.

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

[0014] 1. The utility model rotates the bolt after the roller pushes the device to a suitable position, so that the mounting plate threadedly connected to the bolt descends. The descent of the mounting plate drives the limit plate to descend and presses the roller tightly until it cannot move, thereby completing the fixation of the device and preventing the movement of the device from affecting the installation of the elevator door.

[0015] 2. The utility model drives the two mounting blocks to move closer to or away from each other through a motor, and further drives the two first extrusion plates and the second extrusion plates to move synchronously, so that the device can adapt to elevator doors of different sizes, and the clamping stability is improved through two extrusion positions.
