The second plate 106 is slidably connected to the first plate 105 and the third plate 107 through the sliding blocks 108. A support mechanism is erected between the bottom plate 101 and the third plate 107. A buffer device is erected between the bottom plate 101 and the first plate 105 to prevent the first plate 105 from falling due to excessive load. An adjustment component for changing the support area of the support platform is provided between the first plate 105 and the third plate 107. Support is provided through the bottom plate 101, sliding conditions are provided for the push column 103 through the pipe groove 102, power is provided for the vertical movement of the push column 103 through the hydraulic cylinder 104, and the position of the support platform is changed through the vertical movement of the hydraulic cylinder 104, facilitating the adjustment of the vertical support position of the new type of adjustable elevator shaft support platform. Sliding conditions are provided through the sliding blocks 108, and the horizontal support range of the new type of adjustable elevator shaft support platform is adjusted by the mutual cooperation between the first plate 105, the second plate 106 and the third plate 107;

[0029] In one embodiment, as Figure 2 and Figure 5 shown, the support mechanism includes a first rotating seat 201. Two first rotating seats 201 are fixedly connected to the upper surface of the bottom plate 101. Each first rotating seat 201 is respectively rotatably connected to a sleeve 202. The sleeve 202 is slidably connected to a support column 205. A number of pin holes 204 are provided on the surfaces of the sleeve 202 and the support column 205. A pin block 203 is provided on the pin holes 204. A second rotating seat 213 is provided at the contact position between the support column 205 and the third plate 107. The third plate 107 is rotatably connected to the support column 205 through the second rotating seat 213. Rotating conditions are provided through the first rotating seat 201 and the second rotating seat 213. During the rising or falling process of the first plate 105 and the third plate 107, the pin block 203 is pulled out to change the corresponding positions of the sleeve 202 and the support column 205. After the position adjustment is completed and aligned, the corresponding pin block 203 is inserted into the pin hole 204 to achieve the quick support for the new type of adjustable elevator shaft support platform;

[0030] In one embodiment, as Figure 2 and Figure 3As shown, the buffer device includes a buffer box 206. The lower end of the buffer box 206 is fixedly connected to the bottom plate 101. The front end of the buffer box 206 is fixedly connected to an oil storage tank 207. A connecting pipe 212 that connects the internal spaces of the buffer box 206 and the oil storage tank 207 is provided at the contact position between the buffer box 206 and the oil storage tank 207. The buffer box 206 is slidably connected to a transmission block 208. The upper end of the transmission block 208 is fixedly connected to a first plate 105. The lower end of the transmission block 208 is fixedly connected to a piston block 209 inside the buffer box 206. Buffer oil is filled inside a second plate 106 below the piston block 209. The lower end of the piston block 209 is fixedly connected to a spring member for assisting in buffering. By providing a sliding condition through the buffer box 206, when the load capacity exceeds the support range of the hydraulic cylinder 104, the first plate 105 moves downward at a stall. The first plate 105 drives the transmission block 208 to move downward. The piston block 209 at the lower end of the transmission block 208 moves downward. The piston block 209 squeezes the buffer oil into the internal space of the oil storage tank 207 through the connecting pipe 212. During the movement of the buffer oil, the pressure on the first plate 105 is buffered to avoid injury to personnel;

[0031] In one embodiment, as Figure 4 shown, the spring member includes a damping spring 210. The upper end of the damping spring 210 is fixedly connected to the lower end of the piston block 209. The lower end of the damping spring 210 is fixedly connected to the inner wall of the buffer box 206. A guiding column 211 is provided in the middle of the damping spring 210. During the buffering process of the buffer oil, the damping spring 210 is subjected to the pressure of the piston block 209, and the damping spring 210 undergoes elastic deformation to assist in buffering the buffer oil. When the buffering is over, the damping spring 210 pushes the piston block 209 to reset. During the reset process of the piston block 209, the piston block 209 re-pumps the buffer oil inside the oil storage tank 207 into the buffer box 206 through the connecting pipe 212 to complete the buffering work;

[0032] In one embodiment, as Figure 6 and Figure 7 shown, the adjusting assembly includes fixing blocks 301. A fixing block 301 is fixedly connected to the upper surfaces of the second plate 106 and the third plate 107 respectively. Each fixing block 301 is fixedly connected to a rack 302. A driving element for driving the rack 302 to slide is provided between the two racks 302. By providing a fixing condition through the fixing blocks 301, by changing the position of the rack 302, the rack 302 drives the fixing block 301 to move. Each fixing block 301 drives the corresponding first plate 105 or third plate 107 to move. The first plate 105 and the third plate 107 slide through a sliding block 108. By changing the positions of the first plate 105 and the third plate 107, the support areas of the first plate 105, the second plate 106, and the third plate 107 are changed, which is suitable for working environments of elevator shafts of different sizes;

[0033] In one embodiment, as Figure 7As shown in the figure, the driving element includes a gear 303, which meshes with a rack 302. The lower end of the gear 303 is fixedly connected to the output end of a stepping motor 304, and the fixed end of the stepping motor 304 is fixedly connected to the upper surface of a second plate 106. Power is provided by the stepping motor 304. The stepping motor 304 drives the gear 303 to rotate, and the gear 303 drives the two racks 302 to move, providing power for adjusting the support range of the novel adjustable elevator shaft support platform.

[0034] The above embodiment discloses a novel adjustable elevator shaft support platform. Among them, when the hydraulic cylinder 104 is started, power is provided for the vertical movement of the push column 103 through the hydraulic cylinder 104, and the position of the support platform is changed through the vertical movement of the hydraulic cylinder 104. When the first plate 105 moves to the corresponding position, according to the size of the elevator shaft hole, the stepping motor 304 is started, and power is provided by the stepping motor 304. The stepping motor 304 drives the gear 303 to rotate, and the gear 303 drives the two racks 302 to move. By changing the position of the racks 302, the racks 302 drive the fixed blocks 301 to move, and each fixed block 301 drives the corresponding first plate 105 or third plate 107 to move. The first plate 105 and the third plate 107 slide through the sliding blocks 108. By changing the positions of the first plate 105 and the third plate 107, the supporting areas of the first plate 105, the second plate 106, and the third plate 107 are changed. After the adjustment is completed, the pin block 203 is inserted into the pin hole 204 to fix the sleeve 202 and the support column 205. When the load exceeds the support range of the hydraulic cylinder 104, the first plate 105 moves downward at a stall speed. The first plate 105 drives the transmission block 208 to move downward, and the piston block 209 at the lower end of the transmission block 208 moves downward. The piston block 209 squeezes the buffer oil into the internal of the storage tank 207 through the connecting pipe 212. During the movement of the buffer oil, the pressure on the first plate 105 is buffered. During the buffering process of the buffer oil, the damping spring 210 is pressured by the piston block 209, and the damping spring 210 undergoes elastic deformation to assist the buffer oil in buffering. When the buffering is completed, the damping spring 210 pushes the piston block 209 to reset. During the reset process of the piston block 209, the piston block 209 pumps the buffer oil inside the storage tank 207 back into the buffer tank 206 through the connecting pipe 212 to complete the buffering work.

[0035] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
