DETAILED DESCRIPTION

[0028] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0029] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0030] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0031] Example

[0032] like Figures 1 to 5 As shown, this embodiment includes symmetrically arranged crawlers 1 for easy movement during construction on soft-base pavement and impact columns 4 for strengthening road construction on soft-base pavement. The arrangement of the crawlers 1 increases the contact area between the device and the ground through the crawlers 1 even when the device is under heavy conditions, and even when driving on soft-base pavement, it can still ensure smooth movement and facilitate operation;

[0033] The inner wall of the crawler track 1 is rotatably connected with a plurality of rollers 3 for adjustment and guiding which are distributed at intervals. The two end sides of the rollers 3 are rotatably connected with angle plates which are welded to the fixing frames 2, thereby forming two crawler mechanisms. A fixing plate 8 for easy connection is welded between the crawler mechanisms. A cab 7 is provided at one end of the top of the fixing plate 8. A transparent window is provided on one side of the cab 7 for easy observation of road conditions during driving. The device can be easily used by controlling 7 during driving.

[0034] A gantry 9 for easy connection is welded to the top of the fixed plate 8. The gantry 9 is located on one side of the cab 7. Two symmetrically arranged cross bars 5 are welded to one side of the gantry 9. A connecting plate 13 for easy fixation is welded between the two cross bars 5. In order to further improve the structural strength of the device, a number of equally spaced and evenly distributed reinforcing rods 18 are welded between the connecting plate 13 and the gantry 9, and an inclined auxiliary plate 12 is welded to one side of the gantry 9. One end of the auxiliary plate 12 is welded to the bottom of the cross bar 15. Through the auxiliary plate 12, the structure between the cross bar 15 and the gantry 9 is triangular. The triangle has stability, thereby improving the structural strength of the device.

[0035] Two connected fixed blocks 6 are welded on the top of the gantry 9, and a rotating shaft 10 is rotatably connected between the two fixed blocks 6. A suspension rope 14 made of high-strength metal wire is wound on the outer peripheral side of the rotating shaft 10. A driving motor 11 is screwed to one side of the fixed block 6, and the output shaft of the driving motor 11 passes through the side wall of the fixed block 6 and is connected to the rotating shaft 10. Driven by the output shaft of the driving motor 11, the driving of the rotating shaft 10 is completed, which facilitates the adjustment of the length of the suspension rope 14.

[0036] In order to prevent the impact column 4 connected to the suspension rope 14 from affecting the output shaft of the drive motor 11 during free fall, a spacing sensor can be set between the bottom of the linear motor 15 and the impact column 4. By checking the relative distance of the impact column 4, the output shaft of the drive motor 11 can be disconnected from the rotating shaft 10 during free fall, thereby avoiding damage to the components inside the drive motor 11 and increasing the service life of the device.

[0037] Two bricks are welded to the top of the connecting plate 13, and a support wheel 22 is rotatably connected between the bricks. The support wheel 22 is slidably connected to the suspension rope 14. Two connecting blocks 19 connected to the connecting plate 13 are welded on one side of the brick. A rotatably connected guide wheel 21 is provided between the connecting blocks 19. The guide wheel 21 is located on one side of the through hole 20. A through-type through hole 20 for easy connection is provided in the middle of the connecting plate 13. The inner wall of the through hole 20 is slidably connected to the suspension rope 14, and one end of the suspension rope 14 is connected to the impact column 4. The arrangement of the support wheel 22 and the guide wheel 21 can effectively reduce friction loss and improve the service life of the device.

[0038] A linear motor 15 for lateral adjustment is welded at the bottom of the connecting plate 13. A through-type through groove 17 is provided at the fixed part of the linear motor 15. The through groove 17 is connected to the through hole 20. A horizontal plate 16 for connection is welded between the moving parts of the linear motor 15. A through-type circular hole is provided between the horizontal plates 16. A rolling ball bearing is provided on the inner wall of the circular hole. The ball bearing is slidably connected to the suspension rope 14. By controlling the movement of the moving part of the linear motor 15, the position of the suspension rope 14 is adjusted, so that when the device is constructed on the same horizontal line, the use area of ​​the device is increased, the time of machine movement is reduced, and the construction efficiency is improved.

[0039] The lifting rope 14 passes through the circular hole and is connected to the impact column 4. By cooperating with the rotation of the output shaft of the driving motor 11, the impact column 4 is raised under the action of the lifting rope 14. With the cooperation of dynamic potential energy and gravity potential energy, the reinforcement of the soft base road surface is completed, which is easy to operate.

[0040] In order to improve the overall stability of the device during operation, a counterweight and a fuel tank can be set on one side of the cab 7. By adding the counterweight, the impact column 4 will not cause a large tilt problem to the entire device during the lifting and lowering process, thereby improving the safety of the device.

[0041] The drive motor 11 and the linear motor 15 are both conventional instruments. Their working principles, sizes and models are irrelevant to the functions of the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0042] How it works

[0043] When the operator uses the soft soil foundation reinforcement device for road construction, he opens the door of the cab 7, starts the machine, drives the device as a whole to the place where the soft soil foundation road surface needs to be reinforced through the crawler 1, controls the output shaft of the driving motor 11 to rotate, drives the rotating shaft 10 connected to the output shaft to rotate, completes the collection of the suspension rope 14, and then disconnects the output shaft of the driving motor 11 from the rotating shaft 10 after the impact column 4 reaches the specified height, so that the impact column 4 directly acts on the soft soil foundation road surface, repeatedly beats, and completes the road surface reinforcement;

[0044] Finally, by controlling the movement of the moving part of the linear motor 15, the suspension rope 14 is driven to move, and the combination of the through hole 20, the through groove 17 and the round hole is coordinated to complete the overall movement, which is convenient for construction of areas of different widths on the same straight line and improves construction efficiency.
