Description

Technical Field

[0001] This utility model relates to the field of engineering devices, and in particular to a prestressed pipe pile hammering device. Background Technology

[0002] Prestressed pipe piles are prestressed soil piles with a circular cross-section formed by centrifugal and prestressing processes. When installing prestressed pipe piles, geological surveys are required to determine whether the prestressed pipe piles are suitable for installation.

[0003] A prestressed concrete pipe pile hammering device includes a fixed sleeve fixed to the top side wall of the prestressed concrete pipe pile and a hammer located above the fixed sleeve. The hammering of the hammer causes the prestressed concrete pipe pile to sink and insert to a specified depth. However, conventional prestressed concrete pipe pile hammering devices do not have protective devices around the top of the fixed sleeve. This allows gravel or other hard objects located at the top of the fixed sleeve to easily fall onto it. When the hammering device strikes downwards, it may squeeze or push the gravel or other hard objects outwards, causing them to fly out and potentially injure nearby personnel. Therefore, a prestressed concrete pipe pile hammering device is needed to shield and protect the top of the fixed sleeve to prevent personnel injury. Utility Model Content

[0004] The purpose of this utility model is to provide a prestressed pipe pile hammering device to overcome the defect that gravel or other hard objects on the top of the fixed sleeve can easily break off and injure people around it.

[0005] The technical solution to achieve the above objective is: a prestressed pipe pile hammering device, comprising a fixed sleeve installed and fixed at the top end of the prestressed pipe pile body, a hammering component installed on the fixed sleeve, an installation component connected to the top side wall of the fixed sleeve, a support component installed on the installation component, a protective component installed on the support component, and an auxiliary component installed on the protective component.

[0006] Preferably, the mounting component includes a mounting block, a through hole, a support rod, and a connecting spring. Multiple mounting blocks are circumferentially arrayed on the top side wall of the fixed sleeve. The side wall of the mounting block has a through hole, and a support rod is movably connected in the through hole. A connecting spring is connected to both the top and bottom ends of the mounting block.

[0007] Preferably, the support includes a placement block, a placement groove, and a sliding hole. Both ends of the support rod are connected to placement blocks. The side wall of the placement block facing away from the fixed sleeve has a placement groove. The top of the side wall of the placement groove has a sliding hole. One end of the connecting spring is connected to the side wall of the placement block.

[0008] Preferably, the protective component includes an inner block, a slider, a connecting rod, a round rod, a protective net, and a buffer spring. The inner block is slidably connected to the side wall of the placement groove, and the top of the inner block is connected to the slider. The side wall of the slider is slidably connected to a sliding hole. A connecting rod is connected to the side wall of the inner block facing the opening of the placement groove. A round rod is connected to the side wall of the connecting rod. Protective nets are connected to both ends of the round rod and to its side wall. A buffer spring is connected to the side wall of the inner block. One end of the buffer spring is connected to the inner side wall of the placement groove, and a damper is provided inside the buffer spring.

[0009] Preferably, the top end of the round rod is located above the top end of the fixed sleeve, and the bottom end of the round rod is located below the top end of the fixed sleeve.

[0010] Preferably, the length of the sliding hole is less than the length of the placement groove.

[0011] Preferably, the auxiliary component includes screw holes, a top plate, and screws. The top of the placement block has two symmetrically distributed screw holes, and the side wall of the top plate has a circular hole. A screw is inserted into the circular hole, and the side wall of the screw is threadedly connected to the screw hole.

[0012] Preferably, the top end of the top plate is set as a slope.

[0013] The beneficial effects of this utility model are:

[0014] 1) When the protective net is impacted by hard objects such as gravel splashed from the top of the fixed pipe sleeve, the protective net will squeeze the connecting rod, the connecting rod will press the inner block, and the inner block will press the buffer spring, thereby buffering the impact on the protective net and at the same time achieving the effect of blocking hard objects such as gravel.

[0015] 2) When the placement block is subjected to impact, it will compress one of the connecting springs and stretch the other connecting spring. The placement block can push the support rod, so that the placement block and the support rod have a certain amount of room to move. This avoids the placement block having no room to move when it is impacted. In addition, the height of the placement block can be dynamically adjusted, so that the placement block can drive the protective component to move up and down dynamically. This also allows the protective net to have room to move, reducing the damage to the protective net due to hard impact. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Reference Appendix Figure 1-6 A prestressed pipe pile hammering device includes a fixed sleeve 2 installed and fixed on the top end of the prestressed pipe pile body 1, a hammering component 3 installed on the fixed sleeve 2, an installation component 4 connected to the top side wall of the fixed sleeve 2, a support component 5 installed on the installation component 4, a protective component 6 installed on the support component 5, and an auxiliary component 7 installed on the protective component 6.

[0027] Reference Appendix Figure 2-4The mounting component 4 includes a mounting block 401, a through hole 402, a support rod 403, and a connecting spring 404. Multiple mounting blocks 401 are circumferentially connected to the top side wall of the fixed sleeve 2. The side wall of the mounting block 401 is provided with a through hole 402. The support rod 403 is movably connected in the through hole 402. The top and bottom ends of the mounting block 401 are both connected to the connecting spring 404.

[0028] Reference Appendix Figure 2-6 The support member 5 includes a placement block 501, a placement groove 502, and a sliding hole 503. Both ends of the support rod 403 are connected to the placement block 501. The side wall of the placement block 501 facing away from the fixed tube sleeve 2 has a placement groove 502. The top of the side wall of the placement groove 502 has a sliding hole 503. One end of the connecting spring 404 is connected to the side wall of the placement block 501. The length of the sliding hole 503 is less than the length of the placement groove 502.

[0029] When the placement block 501 is subjected to an impact force, the placement block 501 will compress one of the connecting springs 404 and stretch the other connecting spring 404. The placement block 501 can push the support rod 403, so that the placement block 501 and the support rod 403 have a certain amount of movement space, so as to avoid the placement block 501 having no room for movement when it is impacted. In addition, the height of the placement block 501 can be dynamically adjusted, so that the placement block 501 can drive the protective part 6 to move up and down dynamically, so that the protective net 605 can also have room for movement, reducing the damage of the protective net 605 due to hard impact.

[0030] Reference Appendix Figure 2-6 The protective component 6 includes an inner block 601, a slider 602, a connecting rod 603, a round rod 604, a protective net 605, and a buffer spring 606. The inner block 601 is slidably connected to the side wall of the placement groove 502. The top of the inner block 601 is connected to the slider 602. The side wall of the slider 602 is slidably connected to the sliding hole 503. The side wall of the inner block 601 facing the opening of the placement groove 502 is connected to the connecting rod 603. The side wall of the connecting rod 603 is connected to the round rod 604. The two ends of the round rod 604 and the side wall of the round rod 604 are all connected to the protective net 605. The side wall of the inner block 601 is connected to the buffer spring 606. One end of the buffer spring 606 is connected to the inner side wall of the placement groove 502. A damper is provided inside the buffer spring 606. The top of the round rod 604 is located above the top of the fixed sleeve 2, and the bottom of the round rod 604 is located below the top of the fixed sleeve 2.

[0031] The placement block 501 drives the inner block 601 to move through the placement slot 502. The inner block 601 and the other parts of the protective member 6 form a whole. Therefore, the entire protective member 6 will move vertically up and down with the placement block 501.

[0032] Because the protective net 605 is located around the top of the fixed sleeve 2, when hard objects such as gravel are splashed from the top of the fixed sleeve 2 to the surrounding area, they will be intercepted by the protective net 605. When the protective net 605 is impacted by the hard objects such as gravel splashed from the top of the fixed sleeve 2, the protective net 605 will squeeze the connecting rod 603, the connecting rod 603 will press the inner block 601, and the inner block 601 will press the buffer spring 606, thereby buffering the impact on the protective net 605 and at the same time achieving the effect of blocking hard objects such as gravel.

[0033] Reference Appendix Figure 4-6 The auxiliary component 7 includes screw holes 701, a top plate 702 and screws 703. The top of the placement block 501 has two symmetrically distributed screw holes 701. The side wall of the top plate 702 has a round hole, and a screw 703 is inserted into the round hole. The side wall of the screw 703 is threadedly connected to the screw hole 701. The top of the top plate 702 is set as a slope.

[0034] Align the round hole with the screw hole 701, and position the top edge of the inclined surface of the top plate 702 toward the fixed sleeve 2 side, so that no debris enters the sliding hole 503, and the debris falls down along the inclined surface, reducing the amount of debris retained at the top of the placement block 501.
