It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0032] As Figures 1 - 5 shown, the present invention provides a crane hydraulic telescopic rod with a self-supporting bottom plate, including a hydraulic rod 1, a support plate 2 is installed on the surface of the hydraulic rod 1, and an adjusting device 3 is provided on the surface of the support plate 2.

[0033] The following specifically describes the specific settings and functions of its adjusting device 3.

[0034] As Figures 3 - 5As shown in the figure, the adjusting device 3 includes two connecting plates 301. Both of the two connecting plates 301 are fixedly connected to the support plate 2. An adjusting groove 302 is formed on the surface of the connecting plate 301, and a clamping groove 303 is formed on the surface of the connecting plate 301. A clamping bead 304 is slidably connected to the surface of the clamping groove 303. A connecting rod 305 is fixedly connected to the arc surface of the clamping bead 304. A moving frame 306 is slidably connected to the surface of the connecting rod 305. A spring 307 is sleeved on the arc surface of the connecting rod 305. Both ends of the spring 307 are fixedly connected to the connecting rod 305 and the moving frame 306 respectively. Two screw rods 308 are threadedly connected to the surface of the moving frame 306. One end of each of the two screw rods 308 is rotatably connected to a slider 309. The surface of the slider 309 is slidably connected to a chute 310. The chute 310 is formed on the surface of the connecting plate 301. One end of the connecting rod 305 is fixedly connected to an extension plate 311. A lead screw 312 is threadedly connected to the surface of the extension plate 311. A friction plate 313 is threadedly connected to the arc surface of the lead screw 312. The rectangular groove 315 will drive the lead screw 312 to rotate. Then, the lead screw 312 will rotate in the direction close to the friction plate 313 by virtue of its own thread. When the lead screw 312 enters the friction plate 313, the positions of the friction plate 313 and the extension plate 311 are fixed. At this time, the friction plate 313 and the lead screw 312 can increase the friction between the contact surface of the extension plate 311 and the ground, improving the stability of the extension plate 311. A number of anti-slip protrusions 314 are fixedly connected to the surface of the friction plate 313. The number of anti-slip protrusions 314 is evenly distributed on the surface of the friction plate 313. The friction plate 313 will drive the anti-slip protrusions 314 to contact the ground. At this time, the anti-slip protrusions 314 can increase the friction between the contact surface of the friction plate 313 and the ground. A rectangular groove 315 is formed on the surface of the lead screw 312. A rectangular rod 316 is slidably connected to the surface of the rectangular groove 315. A turning handle 317 is fixedly connected to one end of the rectangular rod 316. Insert the rectangular rod 316 on the turning handle 317 into the rectangular groove 315, then rotate the turning handle 317. Then, the turning handle 317 will drive the rectangular rod 316 to rotate. At this time, the rectangular rod 316 will drive the rectangular groove 315 to rotate. Then, the rectangular groove 315 will drive the lead screw 312 to rotate. At this time, the turning handle 317, the rectangular rod 316 and the rectangular groove 315 can facilitate the rotation of the lead screw 312. An elastic cord 318 is fixedly connected to the surface of the turning handle 317. The other end of the elastic cord 318 is fixedly connected to the extension plate 311. The turning handle 317 will drive one end of the elastic cord 318 to move. At this time, the elastic cord 318 can prevent the turning handle 317 from being lost. A pointed cone 319 is fixedly connected to one end of the lead screw 312. The pointed cone 319 is a stainless steel cone. The lead screw 312 will drive the pointed cone 319 to move. At this time, the pointed cone 319 can facilitate the lead screw 312 to enter the friction plate 313. A ball 320 is rotatably connected to the surface of the slider 309. The ball 320 is slidably connected to the chute 310. The slider 309 will drive the ball 320 to roll along the surface of the chute 310.At this time, the ball 320 can reduce the frictional force between the contact surface of the slider 309 and the chute 310. A handle 321 is fixedly connected to the surface of the extension plate 311. The cross-section of the handle 321 is in the shape of a straight line. When the handle 321 is pulled in the direction away from the hydraulic rod 1, the handle 321 will drive the extension plate 311 to move in the same direction. At this time, the handle 321 with a cross-section in the shape of a straight line can facilitate the staff to stretch the extension plate 311.,

[0035] The overall working principle is as follows. When it is necessary to expand the contact surface between the support plate 2 on the hydraulic rod 1 and the ground during use, first pull the handle 321 in the direction away from the hydraulic rod 1. The handle 321 will drive the expansion plate 311 to move in the same direction. At this time, the handle 321 with a cross-section of a straight line can facilitate the staff to stretch the expansion plate 311. Then the expansion plate 311 will drive the connecting rod 305 to move, and at the same time, the connecting rod 305 will slide along the surface of the moving frame 306. Then the connecting rod 305 will drive the ball 304 to disengage from the card slot 303. Then the connecting rod 305 will drive one end of the spring 307 to move. At this time, the spring 307 itself will generate an outward elastic force, which can help the ball 304 to quickly reset. Then rotate the expansion plate 311 in the direction close to the ground. Then the expansion plate 311 will drive the connecting rod 305 to rotate. At this time, the connecting rod 305 will drive the moving frame 306 to rotate along the surface of the connecting plate 301. At the same time, the moving frame 306 will drive the screw rod 308 to rotate. Then the screw rod 308 will drive the slider 309 to rotate along the surface of the sliding groove 310. At the same time, the slider 309 will drive the ball 320 to roll along the surface of the sliding groove 310. At this time, the ball 320 can reduce the friction between the contact surface of the slider 309 and the sliding groove 310. Then when the expansion plate 311 contacts the ground, first the expansion plate 311 will drive the friction plate 313 to contact the ground. At the same time, the friction plate 313 will drive the anti-slip protrusions 314 to contact the ground. At this time, the anti-slip protrusions 314 can increase the friction between the contact surface of the friction plate 313 and the ground. When the friction plate 313 needs to be replaced, first insert the rectangular rod 316 on the turning handle 317 into the rectangular groove 315. Then the turning handle 317 will drive one end of the elastic rope 318 to move. At this time, the elastic rope 318 can prevent the turning handle 317 from being lost. Then rotate the turning handle 317. Then the turning handle 317 will drive the rectangular rod 316 to rotate. At this time, the rectangular rod 316 will drive the rectangular groove 315 to rotate. Then the rectangular groove 315 will drive the screw rod 312 to rotate. At this time, the turning handle 317, the rectangular rod 316 and the rectangular groove 315 can facilitate the rotation of the screw rod 312. Then the screw rod 312 will move in the direction away from the friction plate 313 by means of its own thread. When the screw rod 312 is disengaged from the friction plate 313, the damaged friction plate 313 can be replaced. At this time, the turning handle 317 can be rotated in the reverse direction. Then the turning handle 317 will drive the rectangular rod 316 to rotate. Then the rectangular rod 316 will drive the rectangular groove 315 to rotate. At the same time, the rectangular groove 315 will drive the screw rod 312 to rotate. Then the screw rod 312 will rotate in the direction close to the friction plate 313 by means of its own thread. At the same time, the screw rod 312 will drive the pointed cone 319 to move. At this time, the pointed cone 319 can facilitate the screw rod 312 to enter the friction plate 313. Then when the screw rod 312 enters the friction plate 313, the positions of the friction plate 313 and the expansion plate 311 are fixed.At this time, the friction plate 313 and the lead screw 312 can increase the friction force between the expansion plate 311 and the ground contact surface, improving the stability of the expansion plate 311. By setting the adjusting device 3, through the mutual cooperation of the connecting plate 301, the adjusting groove 302, the clamping groove 303, the clamping bead 304, the connecting rod 305, the moving frame 306, the spring 307, the screw 308, the slider 309, the sliding groove 310 and the expansion plate 311, the contact area between the support plate 2 and the ground can be increased, avoiding the situation that during the use of the support bottom plate carried by the hydraulic telescopic rod of the crane, due to different ground environments, when encountering a relatively soft ground environment, the force received by the crane hydraulic rod 1 will be transmitted to the support plate 2, causing the support plate 2 to sink into the ground, resulting in the crane shaking and affecting the stability during the use of the crane. The contact area between the support plate 2 and the ground is increased, further improving the stability during the use of the crane.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
