[0008] A first groove is formed on one side of the outer rectangular plate, and a same group of stabilizing components for ensuring the stability of the two outer rectangular plates is arranged between the two first grooves.

[0009] In a possible design, the lifting assembly includes a mounting block fixedly connected to one side of the steel arch frame body, the internal threads of the two mounting blocks on the same side are penetrated by the same fixing screw, a nut is threadedly sleeved on one end of the fixing screw, a limiting groove is provided on one side of the steel arch frame body, and the same reinforcing plate is clamped between the two limiting grooves.

[0010] In a possible design, the brake assembly includes a limit rod that slides through one side of the arc groove, one end of the limit rod is fixedly connected to a side plate, and two symmetrically arranged No. 1 tension springs are fixedly connected between one side of the side plate and one side of the inner extension plate.

[0011] In a possible design, the stabilizing assembly includes a same sleeve plate rotatably connected between the inner walls on both sides of the first groove, one end of the sleeve plate slides through an inner plate, the ends of the two inner plates close to each other are respectively fixedly connected to a U-shaped frame and a connecting block, one end of the connecting block is fixedly connected to a convex plate, and the convex plate is rotatably connected to the inside of the U-shaped frame.

[0012] In a possible design, a rectangular groove is provided at one end of the inner plate, and positioning grooves are provided on the inner walls on both sides of the rectangular groove. The bottom inner wall of the sleeve plate is slidably connected with two symmetrically arranged sliding plates, and the same No. 2 tension spring is fixedly connected between the two sliding plates. A positioning block is fixedly connected to one side of the sliding plate, and the positioning block is engaged with the positioning groove.

[0013] In a possible design, two symmetrically arranged transverse holes are opened at one end of the sleeve plate, and an extended U-shaped plate is slidably connected to the bottom inner wall of the sleeve plate. The extended U-shaped plate slides through the transverse hole, and an arc-shaped plate is fixedly connected to one end of the transverse hole. The same No. 3 tension spring is fixedly connected between the inner wall of one side of the extended U-shaped plate and the inner wall of one side of the sleeve plate, and the arc-shaped plate is used in conjunction with the two sliding plates.

[0014] In a possible design, an elliptical hole is opened on the top of the sleeve plate, a round rod is fixedly connected to the top of the arc plate, and the top of the round rod passes through the elliptical hole and is fixedly connected to an operating block.

[0015] In a possible design, a clamping plate is fixedly connected to one side of the side panel, a second clamping hole is opened on one side of the sleeve plate, a clamping groove is opened on one side of the inner plate, and a first clamping hole is opened on one side of the outer rectangular plate, and the first clamping hole, the second clamping hole and the clamping groove are clamped with the clamping plate.

[0016] A steel arch support method that is easy to assemble, specifically comprising the following steps:

[0017] S1. Unfolding device: First, unfold the device from the folded state, pull the side plate horizontally, drive the limit rod and the clamping plate to move horizontally, and release the braking state of the steel arch frame body and the inner and outer plates;

[0018] S2. Adjust the cover plate and the inner plate: Move the two outer rectangular plates away from each other to make the cover plate unfold and flatten. At this time, the extended U-shaped plate and the arc plate extend under the elastic force of the No. 3 tension spring. When it needs to be stored, the round rod is moved by the operating block to reset the extended U-shaped plate, and then the cover plate can be reversed and reset;

[0019] S3. Fix the steel arch frame body: rotate the two steel arch frame bodies closer to each other, fix the two mounting blocks with fixing screws and nuts, and insert the reinforcing plate into the limiting groove to improve the stability of the steel arch frame body. After the limiting rod is retracted, one end of the steel arch frame body is abutted to improve the stability again;

[0020] S4. Adjust the height: Start the multi-stage hydraulic rod, drive the inner extension plate upward through the piston rod, and adjust the height of the device to adapt to terrains of different heights;

[0021] S5. Fix the base: Finally, use bolts to fix the two bases to the ground to further improve the stability of the device.

[0022] In the present application, when in use, the device is in a folded state, and the device needs to be unfolded to achieve the supporting effect. At this time, the side plate can be pulled laterally, and the side plate drives the limit rod and the card plate to move laterally. At this time, the limit rod is moved out from the inside of the arc groove, so that the limit rod is moved out from one side of the steel arch frame body, and then the steel arch frame body can be moved out from the inside of the arc groove;

[0023] At the same time, the side plate drives the card plate to move horizontally, and the card plate can be moved out from the inside of the card slot and the second card hole, releasing the braking state of the two sleeve plates and the inner plate. Since the two sleeve plates are in a slightly inclined state when stored and are located inside the first groove, the U-shaped frame and the connecting block are always in a connected state;

[0024] When the braking state of the two sleeves is released, the two outer rectangular plates can be moved away to expand the two sleeves. When the two sleeves are laid flat, the extended U-shaped plate has space to move out from the inside of the transverse hole. At this time, the extended U-shaped plate and the arc plate extend under the elastic force of the No. 3 tension spring. When it is necessary to store them, the round rod must be moved by the operating block to reset the extended U-shaped plate, and then the sleeve can be reversed and reset;

[0025] Then the arc-shaped plate moves out from the inside of the two sliding plates. At this time, the two sliding plates approach each other under the tension of the second tension spring. The two sliding plates drive the two positioning blocks to approach each other. At this time, the positioning blocks move out from the inside of the positioning grooves to release the braking state of the inner plates. At this time, the two inner plates can approach each other, increasing the distance between the two outer rectangular plates, thereby saving space when storing;

[0026] At this time, after the sleeve plate and the inner plate are unfolded, they support the ground to ensure the stability of the device. At this time, the two bases can be fixed to the ground with bolts, which can improve the stability of the device. Then, the two steel arch frame bodies are rotated to make the two steel arch frame bodies close to each other, and the two mounting blocks are in conflict with each other. After the fixing screws are passed through the mounting blocks, the nuts are sleeved on one end of the fixing screws to complete the fixing of the two steel arch frame bodies. At the same time, the reinforcing plates are inserted into the inside of the limit grooves to improve the stability of the two steel arch frame bodies.

[0027] When the limit rod is retracted, it will resist one end of the steel arch frame body, thereby further improving the stability of the steel arch frame body. After the adjustment is completed, the two multi-stage hydraulic rods are started, and the piston rods of the multi-stage hydraulic rods drive the inner extension plate to move up, thereby adjusting the height of the inner extension plate, thereby supporting terrains of different heights, and has a wide range of applications.

[0028] Beneficial effects: Easy to operate: The device is easy to carry and transport in a folded state, and can be unfolded with simple operations when in use, which greatly reduces the difficulty and complexity of operation.

[0029] Strong stability: Through the cooperation of side panels, limit rods, clamps and other components, the steel arch frame body and the inner and outer plates are firmly supported, which improves the overall stability of the device.

[0030] Wide range of applications: The design of multi-stage hydraulic rods enables the device to support terrains of different heights, meeting the needs of different working environments.

[0031] Save space: When stored, the components can fit tightly together, which greatly saves space and facilitates storage and transportation. BRIEF DESCRIPTION OF THE DRAWINGS
