[0025] A hydraulically driven telescopic auxiliary arm for a pile driver, comprising:

[0026] The main body includes an auxiliary arm 1, a rotating member 12 and a connecting member 13 are installed on the surface of the auxiliary arm 1, a main arm 11 is installed on the surface of the auxiliary arm 1 through the rotating member 12, a cylinder 14 is movably connected to the surface of the connecting member 13, a movable rod 15 is movably connected to the inner surface of the cylinder 14, an oil pipe 16 is fixedly connected to the surface of the cylinder 14, the auxiliary arm 1 and the main arm 11 are connected through the rotating member 12 and rotate around it, and two groups of connecting members 13 are provided, one group is installed on the auxiliary arm 1, and the other group is installed on the main arm 11, so that the cylinder 14 and the movable rod 15 can rotate on the two groups of connecting members 13 respectively, and the cylinder 14, the movable rod 15 and the oil pipe 16 form a hydraulic device that can drive the auxiliary arm 1 to move to meet the operation requirements;

[0027] The limiting mechanism includes a pressing plate 2, which is installed on the surface of the main arm 11. The surface of the main arm 11 is fixedly connected with a fixed block 21 and a mounting bin 24. The surface of the pressing plate 2 is fixedly connected with a rotating block 22. A rotating hole 23 is provided inside the fixed block 21. A connecting hole 25 is provided on the surface of the mounting bin 24. A pull rod 26 is installed on the surface of the mounting bin 24. A partition 27 and a support spring 28 are movably connected to the inner surface of the mounting bin 24. A socket 29 is provided on the surface of the pressing plate 2. One side of the pressing plate 2 is connected to the fixed block 21 through the rotating block 22, and the other side is against the main arm 11.

[0028] Furthermore, the pressure plate 2 is abutted and connected to the surface of the oil pipe 16, and the cross-section of the pressure plate 2 is "L"-shaped. Two groups of fixed blocks 21 and rotating blocks 22 are provided. The two groups of fixed blocks 21 and rotating blocks 22 are installed on both sides of the pressure plate 2. The rotating block 22 is rotatably connected to the surface of the rotating hole 23. The cross-section of the mounting bin 24 is in a U-shaped shape. The pressure plate 2 and the fixed block 21 are connected through the rotating block 22 and the rotating hole 23, so that the pressure plate 2 can rotate around the rotating block 22 as the center.

[0029] Furthermore, two groups of connecting holes 25 are provided, and the two groups of connecting holes 25 are opened on both sides of the installation bin 24. The surface of the pull rod 26 is "T"-shaped. The pull rod 26 passes through the connecting hole 25 and is connected to the surface of the installation bin 24. The pull rod 26 is plugged into the surface of the socket 29, and the partition 27 is abutted against the surface of the installation bin 24. Under the connection between the pull rod 26 and the partition 27, the movement of the pull rod 26 can drive the partition 27 to slide on the surface of the installation bin 24 and the main arm 11, thereby making the support spring 28 telescopic and transformable. Under the connection between the pull rod 26 and the socket 29, the limiting effect of the pressure plate 2 can be achieved.

[0030] Furthermore, one end of the support spring 28 is fixedly connected to the inner surface of the installation bin 24, and the other end of the support spring 28 is fixedly connected to the surface of the partition 27. The diameter of the socket 29 is the same as the diameter of the connecting hole 25. The support spring 28 can apply a supporting force to the partition 27, thereby making the pull rod 26 more firmly and tightly inserted into the socket 29.

[0031] Furthermore, a protective mechanism is provided on the surface of the movable rod 15, and the protective mechanism includes a sleeve 3, which is installed on the surface of the movable rod 15, and the surface of the sleeve 3 is fixedly connected to a base plate 31, and the surface of the base plate 31 is provided with a first through hole 32 and a second through hole 33, and the surface of the cylinder 14 is fixedly connected to a fixed plate 34, and the surface of the sleeve 3 is provided with a slide groove 36, and the surface of the fixed plate 34 is fixedly connected to a block 35 and a connecting spring 37, and the surface of the movable rod 15 is fixedly connected to a baffle 38. Under the action of the sleeve 3, a large amount of dust can be prevented from adhering to the movable rod 15, thereby reducing the cleaning effect of the dust cover at the front end of the cylinder 14.

[0032] Furthermore, one side of the sleeve 3 is movably connected to the outer surface of the cylinder 14, and the other side of the sleeve 3 is abutted and connected to the surface of the baffle 38. The sleeve 3 is slidably connected to the surface of the fixed plate 34. The diameter of the first through hole 32 is larger than the diameter of the second through hole 33. There are two groups of blocks 35 and slide grooves 36. There are two groups of second through holes 33 and they are opened on both sides of the bottom plate 31. The cylinder 14 and the oil pipe 16 can be installed through the first through hole 32 and the second through hole 33, so that the sleeve 3 is not hindered when moving.

[0033] Furthermore, two groups of blocks 35 are fixedly connected to both sides of the fixed plate 34, and two groups of slide grooves 36 are opened on both sides of the sleeve 3. The blocks 35 are engaged and connected to the surface of the slide grooves 36. One end of the connecting spring 37 is fixedly connected to the surface of the bottom plate 31, and the other end of the connecting spring 37 is fixedly connected to the surface of the fixed plate 34. The cross-section of the block 35 is "T"-shaped. Under the connection between the block 35 and the slide groove 36, the sleeve 3 can be limited so that it always moves along the direction of the slide groove 36 and the movable rod 15. Two groups of connecting springs 37 are provided and installed on both sides of the cylinder 14. The number of each group of connecting springs 37 is two. The connecting springs 37 can apply tension to the bottom plate 31, thereby driving the sleeve 3 to press against the surface of the baffle 38.

[0034] Working principle: Before using the auxiliary arm 1 and the main arm 11, first open the pressure plate 2 and place the oil pipe 16 between the fixed block 21 and the installation bin 24, then move the pressure plate 2 to make it rotate around the rotating block 22, and at the same time pull the pull rod 26 to make it slide on the surface of the connecting hole 25, thereby driving the partition 27 to slide on the inner surface of the installation bin 24, and the support spring 28 is in a compressed state. When the pressure plate 2 is against the main arm 11 and the oil pipe 16, release the pull rod 26. At this time, the pull rod 26 is inserted into the socket 29 under the action of the supporting force exerted by the support spring 28 to complete the limiting of the oil pipe 16.

[0035] During the movement of the movable rod 15, the two sets of connecting springs 37 always apply tension to the bottom plate 31, and then the sleeve 3 is always against the baffle 38 through the bottom plate 31, and in the process of movement, the block 35 always slides on the outer surface of the slide groove 36 and the sleeve 3, so that the movable rod 15 is always placed in the sleeve 3, so as to achieve the effect of dustproofing the movable rod 15.
