[0029] The pressure plate 207 is composed of two mutually perpendicular plates, one plate is a short section and the other plate is a long section. The short section is hinged on a small support 227 welded and installed on the cabin body 1. The small supports 227 are arranged in three groups of two. The long section is rotatably installed on the movable plate 206 by means of two small connecting rods 208. One end of the two small connecting rods 208 is hinged on the pressure plate 207, and the other end is hinged on the movable plate 206. A gap is provided between the two small connecting rods 208.

[0030] An L-plate 205 is fixedly installed at each of the four corners of the movable plate 206. The four L-plates 205 are evenly arranged around the circumference. Each L-plate 205 is fixedly connected to the movable end of a hydraulic cylinder 204. Each hydraulic cylinder 204 is fixedly installed on each small circular groove 226. The four small circular grooves 226 are evenly arranged around the circumference on the cabin 1.

[0031] The movable plate 206 is a rectangular frame with a notch at the bottom. A flat plate is horizontally connected to one side of the rectangular frame. The flat plate is fixedly connected to the movable rack 210. The movable rack 210 is driven by a reduction mechanism.

[0033] The turntable assembly includes a driving gear 219, which is coaxially connected to the turntable 218 by a circular shaft. The circular shaft rotates in the lower rotating hole 231. The driving gear 219 and the intermediate gear 213 form a gear match. A limiting frame 221 is provided between the turntable 218 and the driving gear 219. The limiting frame 221 is welded obliquely on the cabin body 1. The limiting frame 221 includes two sections, one section is a vertical plate, and two arc plates are symmetrically arranged at the end of the vertical plate. The two arc plates are used to limit the position of the handle assembly. The two arc plates can make the turntable 224 rotate clockwise or counterclockwise, and the push rod 222 can be used to push the turntable 218 to rotate.

[0034] The handle assembly includes a rotating frame 224, which is rotatably mounted on the turntable 218. A tension spring 220 is connected to each end of the rotating frame 224. The two ends of the two tension springs 220 that are close to each other are sleeved and connected to the rotating frame 224, and the two ends of the two tension springs 220 that are far away from each other are respectively hooked and connected to the cabin body 1. A push rod 222 is rotatably provided on the rotating frame 224, and a torsion spring 225 is provided between the push rod 222 and the rotating frame 224. One end of the torsion spring 225 is fixedly connected to the rotating frame 224, and the other end is fixedly connected to the push rod 222; a hole is provided at the end of the rotating frame 224, and the insertion rod 223 is used to insert into the hole of the rotating frame 224 to fix the rotating frame 224. A plug hole 230 is provided on the cabin body 1, and the plug hole 230 is used to accommodate the plug rod 223.

[0035] The push rod 222 is cylindrical, and two inclined support rods are symmetrically arranged on the center of the cylindrical curved surface. The two inclined support rods are used to push the turntable 218 to slide.

[0036] Working principle of the present invention: the present invention directly opens an opening 229 on the cabin body 1, and then hinges the hatch door 202 on the cabin frame 201, and sets the structure of the opening and closing cabin frame 201 in advance, slides the cabin frame 201 into the opening 229, and then uses three pressure plates 207 to fix the cabin frame 201, so as to achieve the effect of conveniently disassembling the hatch door 202.

[0037] First, open the valves of the four hydraulic cylinders 204 to ventilate them and keep them in a relaxed state, push the cabin frame 201 into the opening 229, and the convex plate of the cabin frame 201 on the inner side of the cabin body 1 prevents the cabin frame 201 from sliding through, then unplug the plug rod 223, and then rotate the rotating frame 224 clockwise, one end of the push rod 222 on the rotating frame 224 pushes the turntable 218 to rotate, and the other end of the push rod 222 is stuck on the arc plate on the left side of the limiting frame 221, so that the push rod 222 cannot rotate, that is, the turntable 218 can only be pushed to rotate by the support rod on the left side of the push rod 222, and the support rod on the right side of the push rod 222 is limited by the arc plate on the left side of the limiting frame 221; the left and right sides mentioned in the present invention are based on Figure 7 , Fig.12 The viewing angle is used as the basis.

[0038] The rotation of the turntable 218 drives the driving gear 219 to rotate, and the driving gear 219 meshes with the intermediate gear 213. The intermediate gear 213 drives the intermediate rack 214 to slide, and the intermediate rack 214 drives the side rack 215 to slide, and the side rack 215 drives the lower large gear 212 to rotate. The rotation of the lower large gear 212 causes the connecting shaft 216 and the upper large gear 217 to rotate, and the upper large gear 217 drives the moving rack 210 to slide, and the sliding of the moving rack 210 drives the moving plate 206 to slide close to the cabin frame 201. After the rotating frame 224 rotates for a distance (the rotation angle of the rotating frame 224 is forty-five degrees), the maximum rotation distance is that the right support rod of the push rod 222 does not separate from the arc plate on the left side of the limiting frame 221, and the rotating frame 224 is manually released. Under the action of the tension springs 220 on both sides, the rotating frame 224 will be reset to maintain a neutral position, and the rotating frame 224 will also reset with the push rod 222.

[0039] The reset of the rotating frame 224 will not drive the turntable 218 to rotate. After the rotating frame 224 is reset, the rotating frame 224 is rotated counterclockwise again, and then the movable plate 206 is brought close to the cabin body 1. After multiple rotations, the movable plate 206 is finally made close to the cabin body 1. At the same time, when the movable plate 206 rotates, it drives the three groups of pressure plates 207 to buckle to the cabin frame 201 under the action of the small connecting rod 208, and the cabin frame 201 is clamped and fixed. When the pressure plate 207 is buckled to the cabin frame 201, the long section of the pressure plate 207 is parallel to the cabin body 1.

[0040] At this time, the four hydraulic cylinders 204 are activated to assist in fixing the four corners of the movable plate 206 to stabilize the fixation of the cabin frame 201, and then the insertion rod 223 is inserted into the rotating frame 224 and the insertion hole 230 to prevent the rotating frame 224 from being accidentally touched.

[0041] When it is necessary to disassemble the cabin frame 201, remove the insertion rod 223 and rotate the rotating frame 224 counterclockwise. When rotating counterclockwise, the support rod on the left side of the push rod 222 will be clamped by the arc plate on the right side of the limiting frame 221, and the support rod on the right side of the limiting frame 221 is used to push the turntable 218 to rotate, so that the cabin frame 201 and the hatch door 202 can be easily disassembled.

[0042] Any matters not described in the present invention are applicable to the prior art.
