Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment design, and in particular to a self-recovering road pile. Background Art

[0002] In our daily life, most of the existing ground piles are placed on the ground and fixed with screws. At the same time, the existing ground piles are all hollow cylindrical. When hit, if the impact intensity is not very large, the surface of the ground pile may be deformed by the impact force, and the screws at the bottom of the ground pile may also be deformed and bent due to the impact force received by the ground pile, which brings trouble to maintenance work.

[0003] After searching, the Chinese patent application number CN201710271691.2 discloses a ground pile welding device, including a frame, a chuck, a top block, a gear transmission mechanism, a lateral displacement adjustment mechanism, a lateral displacement driving gear and a welding mechanism. The chuck is rotatably connected to one end of the frame, and the outer periphery of the chuck is fixed with a chuck driving tooth. The top block is slidably connected to the frame. The welding mechanism is connected to the frame through a lateral displacement adjustment mechanism that enables the welding mechanism to move in a direction parallel to the center axis of the chuck. The lateral displacement adjustment mechanism is fixed to the lateral displacement driving gear, and the gear transmission mechanism is respectively engaged with the chuck driving tooth and the lateral displacement driving gear. The ground pile welding device provided by the present invention can drive the rotation of the chuck and the movement of the welding mechanism through the same drive system. The speed ratio between the two movements is strictly determined by the gear ratio and the lateral displacement adjustment mechanism. When the motion resistance changes, the two speeds will change year-on-year, ensuring product quality and improving production efficiency.

[0004] After receiving a low-intensity impact, the existing ground piles may be deformed or offset, requiring manual replacement, which causes trouble. Summary of the invention

[0005] Based on the technical problem that the existing road piles cannot automatically recover when receiving low-intensity impacts, the present invention proposes a self-recovering road pile.

[0006] A self-recovering road ground pile proposed in the present invention comprises a base, threaded rings are fixedly connected on both sides of the base, and the threaded rings are fixedly connected to the ground through threaded screws, a rotating rod is rotatably connected to the top of the base through a rotating shaft, a spring telescopic rod is fixedly connected to the top of the rotating rod, limiting plates are fixedly connected on both sides of the rotating rod, an expansion tube is fixedly connected to the top of the limiting plate, an oil-absorbing resin is arranged inside the expansion tube, a circular hole is opened at the top of the expansion tube, a support rod is slidably connected to the circular hole, and the support rod is adapted to the spring telescopic rod.

[0007] Preferably, the base is rotatably connected to support blocks on both sides of the rotating rod through a rotating shaft, a fixed tube is fixedly connected to one side of the support block, a movable tube is slidably connected to the top of the support block outside the fixed tube, plastic sheets are fixedly connected between the fixed tube and the movable tube on both sides above the support block, vegetable oil is provided between the two plastic sheets, and a first spring is fixedly connected between the fixed tube and the movable tube.

[0008] Preferably, a connecting block is fixedly connected to the top of the fixed tube, a rotating shaft is fixedly connected to one side of the top of the connecting block, and a top plate is fixedly connected to one end of the rotating shaft.

[0009] Preferably, a curved hole is provided inside the bottom end of the connection block, and a first hose is fixedly connected to one end of the curved hole, and the first hose is fixedly connected to the expansion tube.

[0010] Preferably, a circular through hole is provided at the bottom end of the fixed tube, sliding grooves are provided on both sides of the circular through hole, a sliding sheet is slidably connected inside the sliding groove, a second spring is fixedly connected between the sliding sheet and the fixed tube, and a rubber ball is fixedly connected to one end of the sliding sheet.

[0011] Preferably, the fixed tube is fixedly connected to a second hose at the circular through hole, and one end of the second hose is fixedly connected to the expansion tube.

[0012] Preferably, both sides of the top of the base are rotatably connected to tilt rods via a rotating shaft, one end of the tilt rod is rotatably connected to a first roller via a rotating shaft, the top of the base is rotatably connected to a traction rod at one side of the tilt rod via a rotating shaft, one end of the traction rod is fixedly connected to a second roller, and a third spring is fixedly connected between the traction rod and the base.

[0013] Preferably, a curved plate is fixedly connected to the top of the top plate, and a plurality of drainage grooves are provided at the top of the curved plate.

[0014] The beneficial effects of the present invention are:

[0015] 1. By setting a rotating rod, when the pile is hit by a low-intensity impact, the rotating rod is tilted by the impact force until the impact force is completely offset. After that, the oil-absorbing resin is injected into the expansion tube. After encountering the vegetable oil, the resin absorbs it, expands and lifts up the support rod, and straightens the tilted rotating rod;

[0016] 2. By setting the vegetable oil, when it is hit by a low-intensity impact, the movable tube first moves toward the fixed tube at the top of the two support blocks, and the vegetable oil between the movable tube and the fixed tube is squeezed, which buffers the impact force and drives the vegetable oil to be injected into the expansion tube, so that the oil-absorbing resin can push the rotating rod straight;

[0017] 3. By setting a rubber ball, when impacted, the rubber ball prevents the vegetable oil from entering the expansion tube through the second hose due to the impact force, thereby reducing the effect of resisting the impact force. In addition, when the support rod straightens the rotating rod, the oil-absorbing resin automatically removes the vegetable oil, and the vegetable oil enters the second hose between the fixed tube and the movable tube through the second hose due to gravity for recovery;

[0018] 4. By setting a traction rod, when an impact is received, the traction rod receives the impact force and rotates, driving the third spring to stretch, causing the third spring to deform, and the deformation prevents the traction rod from rotating, thereby improving the impact resistance of the device;

[0019] 5. By setting up the curved panel, when it rains, the drainage groove of the top curved panel collects rainwater and discharges it at the same time, preventing rainwater from entering the device and improving the stability of the device.

[0020] In the present invention, by providing a rotating rod and a traction rod, when the device is impacted, the traction rod and the rotating rod resist the impact and tilt at the same time, and automatically return to the center after the impact force disappears, thereby avoiding the situation where the device is tilted and offset when subjected to a low-intensity impact, requiring maintenance by staff.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1

[0030] Reference Figure 1-5 A self-recovering road pile comprises a base 1, threaded rings 2 are welded on both sides of the base 1, and the threaded rings 2 are welded to the ground through threaded screws, a rotating rod 4 is rotatably connected to the top of the base 1 through a rotating shaft, a spring telescopic rod 3 is welded to the top of the rotating rod 4, limiting plates 5 are welded on both sides of the rotating rod 4, an expansion tube 6 is welded to the top of the limiting plate 5, an oil-absorbing resin 8 is arranged inside the expansion tube 6, a circular hole is opened at the top of the expansion tube 6, a support rod 9 is slidably connected to the circular hole of the expansion tube 6, and the support rod 9 is adapted to the spring telescopic rod 3. When the pile is hit with a low intensity, the rotating rod 4 is tilted by the impact force until the impact force is completely offset, and then the oil-absorbing resin 8 is injected into the expansion tube 6, and the resin absorbs the vegetable oil after encountering it, expands and lifts up the support rod 9, and straightens the tilted rotating rod 4.

[0031] In the present invention, the base 1 is rotatably connected to a support block 10 on both sides of the rotating rod 4 through a rotating shaft, a fixed tube 14 is welded on one side of the support block 10, and a moving tube 11 is slidably connected to the top of the support block 10 outside the fixed tube, and plastic sheets 24 are welded between the fixed tube 14 and the moving tube 11 on both sides above the support block 10, and vegetable oil 12 is provided between the two plastic sheets 24, a first spring 13 is welded between the fixed tube 14 and the moving tube 11, and a connecting block 18 is welded on the top of the fixed tube 14. A rotating shaft 25 is welded to one side of the top of the connecting block 18, and a top plate 7 is welded to one end of the rotating shaft 25. A curved hole 15 is provided inside the bottom of the connecting block 18, and a first hose 16 is welded to one end of the curved hole 15. The first hose 16 is welded to the expansion tube 6. When subjected to a low-intensity impact, the movable tube 11 first moves toward the fixed tube 14 at the top of the two supporting blocks 10, and the vegetable oil 12 between the movable tube 11 and the fixed tube 14 is squeezed, which buffers the impact force while driving the vegetable oil 12 to be injected into the expansion tube 6, so that the oil-absorbing resin 8 pushes the rotating rod 4 upward.

[0032] Among them, a circular through hole is opened at the bottom end of the fixed tube 14, and sliding grooves 29 are opened on both sides of the circular through hole of the fixed tube 14. A sliding piece 28 is slidably connected inside the sliding groove 29. A second spring 27 is welded between the sliding piece 28 and the fixed tube 11. A rubber ball 26 is welded at one end of the sliding piece 28. When impacted, the rubber ball 26 prevents the vegetable oil 12 from entering the expansion tube 6 through the second hose 17 due to the impact force, thereby reducing the effect of resisting the impact force. In addition, when the support rod 9 straightens the rotating rod 4, the oil-absorbing resin 14 automatically removes the vegetable oil 12, and the vegetable oil 14 enters the second hose 17 between the fixed tube 14 and the movable tube 11 through the second hose 17 due to gravity for recovery.

[0033] Among them, the fixed tube 14 is welded with a second hose 17 at the circular through hole, and one end of the second hose 17 is welded to the expansion tube. The top of the base 10 is rotatably connected to the tilting rod 23 on both sides through a rotating shaft, and one end of the tilting rod 23 is rotatably connected to the first roller 22 through a rotating shaft. The top of the base 1 is rotatably connected to the traction rod 19 at one side of the tilting rod 23 through a rotating shaft, and a second roller 21 is welded to one end of the traction rod 19. A third spring 20 is welded between the traction rod 19 and the base 1. When impacted, the traction rod 19 rotates due to the impact force, driving the third spring 20 to stretch, and the third spring 20 is deformed. The deformation prevents the traction rod 19 from rotating, thereby improving the impact resistance of the device.

[0034] During use, when the pile is hit with low intensity, the rotating rod 4 is tilted by the impact force until the impact force is completely offset. After that, the oil-absorbing resin 8 is injected into the expansion tube 6. After encountering the vegetable oil, the resin absorbs it, expands and lifts up the support rod 9, thereby straightening the tilted rotating rod 4.

[0035] When subjected to a low-intensity impact, the movable tube 11 first moves toward the fixed tube 14 at the top of the two support blocks 10, and the vegetable oil 12 between the movable tube 11 and the fixed tube 14 is squeezed, which cushions the impact force while driving the vegetable oil 12 to be injected into the expansion tube 6, so that the oil-absorbing resin 8 pushes the rotating rod 4 upward.

[0036] When impacted, the rubber ball 26 prevents the vegetable oil 12 from entering the expansion tube 6 through the second hose 17 due to the impact force, thereby reducing the effect of resisting the impact force. In addition, when the support rod 9 straightens the rotating rod 4, the oil-absorbing resin 14 automatically removes the vegetable oil 12, and the vegetable oil 14 enters the second hose 17 between the fixed tube 14 and the movable tube 11 through the second hose 17 due to gravity for recovery.

[0037] When impacted, the traction rod 19 rotates due to the impact force, driving the third spring 20 to stretch, causing the third spring 20 to deform. The deformation prevents the traction rod 19 from rotating, thereby improving the impact resistance of the device.

[0038] Example 2

[0039] Reference Figure 6 A self-recovering road pile. Compared with Example 1, in order to prevent rainwater from entering the device due to too fast accumulation rate and affecting the operation of the device, a curved panel 30 is welded on the top of the top plate 7, and a plurality of drainage grooves 31 are opened on the top of the curved panel 30. When it rains, the drainage grooves 31 of the top curved panel 30 collect rainwater and discharge it at the same time, preventing rainwater from entering the device and improving the stability of the device.

[0040] During use, when the pile is hit with low intensity, the rotating rod 4 is tilted by the impact force until the impact force is completely offset. After that, the oil-absorbing resin 8 is injected into the expansion tube 6. After encountering the vegetable oil, the resin absorbs it, expands and lifts up the support rod 9, thereby straightening the tilted rotating rod 4.

[0041] When subjected to a low-intensity impact, the movable tube 11 first moves toward the fixed tube 14 at the top of the two support blocks 10, and the vegetable oil 12 between the movable tube 11 and the fixed tube 14 is squeezed, which cushions the impact force while driving the vegetable oil 12 to be injected into the expansion tube 6, so that the oil-absorbing resin 8 pushes the rotating rod 4 upward.

[0042] When impacted, the rubber ball 26 prevents the vegetable oil 12 from entering the expansion tube 6 through the second hose 17 due to the impact force, thereby reducing the effect of resisting the impact force. In addition, when the support rod 9 straightens the rotating rod 4, the oil-absorbing resin 14 automatically removes the vegetable oil 12, and the vegetable oil 14 enters the second hose 17 between the fixed tube 14 and the movable tube 11 through the second hose 17 due to gravity for recovery.

[0043] When impacted, the traction rod 19 rotates due to the impact force, driving the third spring 20 to stretch, causing the third spring 20 to deform. The deformation prevents the traction rod 19 from rotating, thereby improving the impact resistance of the device.

[0044] When it rains, the drainage groove 31 of the top curved panel 30 collects rainwater and discharges it at the same time, preventing rainwater from entering the interior of the device, thereby improving the stability of the device.
