Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile fixing chucks, in particular to a pipe pile fixing chuck for a vibrating hammer. Background Art

[0002] A vibratory pile hammer is a device that generates a strong exciting force to drive objects into the ground after being powered on. It uses an electric motor to drive a pair of eccentric blocks to rotate in opposite directions, so that the lateral centrifugal forces they generate cancel each other out, while the vertical centrifugal forces are superimposed on each other. The high-speed rotation of the eccentric wheel causes the gear box to vibrate vertically up and down, thereby achieving the purpose of pile sinking. It is mainly composed of three parts: a vibration absorber, a vibrator and an electrical device.

[0003] When the side clamp vibrating hammer drives the pile body to move, the pile body is usually fixed on the side; in the prior art, there is a utility model patent with the publication (announcement) number CN215329875U and the name of a clamping device for a side clamp vibrating hammer, which includes a mounting plate, a fixing plate fixedly connected to the front of the mounting plate, a fixing mechanism fixedly connected to the front of the fixing plate, and a stabilizing mechanism fixedly connected to the front of the fixing plate. The clamping device of the side clamp vibrating hammer, by starting the motor, the output shaft of the motor drives the worm to rotate, the two worms can respectively drive the meshing worm wheels to rotate, the two motors can respectively control the two worm wheels to rotate simultaneously and in opposite directions, the clamping plates on the outer sides of the two rotating shafts can rotate to the opposite side to clamp and fix the pile column, when the clamping plates clamp the pile column, the pile column moves to the back to squeeze the inclined surface of the clamping block, the clamping block squeezes the stabilizing telescopic rod and stabilizing spring of the stabilizing assembly, and the reaction force of the stabilizing spring can reinforce the pile column, so that the pile column is fixed more firmly.

[0004] Since the inner diameters of existing pipe piles are of different lengths, when constructing pipe piles with different inner diameters, it is necessary to replace chucks of different specifications to clamp the pipe piles. If the pipe pile does not match the chuck of the vibrating hammer, the pipe pile does not contact one wall of the chuck of the vibrating hammer, which may easily cause deformation of the pipe pile under the action of the vibrating hammer. However, the inner diameter length detection mechanism of the pipe pile is not set on the clamping plate of the equipment of this patent, which may cause certain safety hazards to the equipment. Utility Model Content

[0005] The utility model aims to provide a pipe pile fixing chuck for a vibrating hammer.

[0006] The technical problem solved by the utility model is that the existing equipment has no pipe pile inner diameter length detection mechanism on the clamping plate, which causes the pipe pile to fail to contact with one wall of the vibrating hammer chuck, thereby easily damaging the pipe pile.

[0007] The utility model can be implemented through the following technical scheme: a vibrating hammer uses a pipe pile fixing chuck, comprising a chuck body and two clamping plates slidably connected to the inner cavity thereof, a driving mechanism for driving the two clamping plates to move is arranged in the chuck body, which is a prior art and will not be described in detail here; a detection mechanism for detecting the inner diameter length of the pipe pile is arranged on one side of the two clamping plates away from each other, and the arrangement of the two detection mechanisms is not only convenient for the staff to operate, but also convenient for balancing the equipment; the detection mechanism comprises a detection plate elastically slidably connected to the inner cavity of the clamping plate, and the inclination of the detection plate is equal to that of the clamping plate; the inner cavity of the clamping plate is fixedly connected to the detection plate A second trigger switch is matched with the other, and an alarm electrically connected to the second trigger switch is fixedly installed on the side wall of the chuck body. By moving the chuck body downward, during the downward movement of the chuck body, the detection plates on the two clamping plates are used to detect the inner diameter of the pipe pile. When the inner diameter of the pipe pile meets the requirements, the two clamping plates will move down smoothly. When not, the detection plates will squeeze the support spring in the inner cavity of the clamping plates and cause the support spring to undergo elastic deformation. At the same time, as the detection plates continue to slide, the stop block on them will contact the second trigger switch. At this time, the alarm will sound, which is convenient for the staff to deal with it in time and avoid damage to the pipe pile by the equipment.

[0008] The inner cavity of the clamp body is provided with an adjusting mechanism for enabling the clamping plate to completely enter the inner cavity of the pipe pile.

[0009] A further technical improvement of the utility model is that a soft pad is fixedly installed on one side of the detection plate away from the inner cavity of the clamping plate. When the inner diameter of the pipe pile is detected, the soft pad abuts against the inner wall of the pipe pile, which can protect the pipe pile to the greatest extent. The soft pad is a rubber pad.

[0010] A further technical improvement of the utility model is that the adjustment mechanism includes a counterweight block which is floatingly connected to the center of the bottom end of the chuck body, and the weight of the counterweight block can be selected according to actual usage requirements; a first trigger switch which cooperates with the counterweight block is fixedly installed in the inner cavity of the chuck body, and the pipe pile is brought into contact with the counterweight block by moving the chuck body downward, and as the chuck body continues to move downward, the counterweight block moves upward until it contacts the first trigger switch, and then the two clamping plates clamp the pipe pile through the first trigger switch.

[0011] A further technical improvement of the utility model is that a telescopic assembly is arranged between the chuck body and the counterweight block, and the telescopic assembly includes an outer sleeve fixedly connected to the center of the bottom end of the chuck body, and the inner cavity of the outer sleeve is elastically slidably connected to an inner sleeve fixedly connected to the counterweight block. There are multiple inner sleeves, and the multiple inner sleeves are arranged in sequence.

[0012] A further technical improvement of the utility model is that the inner cavity of the chuck body is provided with a limit assembly for limiting the counterweight block, the limit assembly includes two connecting blocks fixedly connected to the inner cavity of the counterweight block, the inner cavity of the counterweight block and one side away from the connecting block is elastically slidably connected to the limit block, and the inner cavity of the chuck body is provided with a limit groove matching the limit block, so that the counterweight block is limited to facilitate the subsequent clamping of the pipe pile.

[0013] A further technical improvement of the utility model is that the inner cavity of the counterweight block is provided with a linkage component for releasing the limit of the counterweight block, and the linkage component includes two electromagnetic strips with opposite magnetic properties that are embedded in the inner cavities of the connecting block and the limit block, and the electromagnetic strips are electrically connected to the first trigger switch. By moving the chuck body downward, the counterweight block is brought into contact with the top of the pipe pile. Therefore, as the chuck body continues to move downward, the counterweight block will continue to move upward until the counterweight block contacts the first trigger switch. Since the first trigger switch is electrically connected to the chuck body, at this time, the first trigger switch will drive the two clamping plates to clamp the pipe pile through the chuck body. After the pipe pile is processed, the power of the electromagnetic strips is turned on to release the limit of the counterweight block, thereby facilitating the subsequent use of the equipment.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model moves the chuck body downward, and during the downward movement of the chuck body, the detection plates on the two clamping plates are used to detect the inner diameter of the pipe pile. When the inner diameter of the pipe pile meets the requirements, the two clamping plates will move downward smoothly. When it does not meet the requirements, the detection plate will squeeze the supporting spring in the inner cavity of the clamping plate and cause the supporting spring to undergo elastic deformation. At the same time, as the detection plate continues to slide, the stop block on it will contact the second trigger switch. At this time, the alarm will sound, which is convenient for the staff to deal with it in time, avoid the equipment from damaging the pipe pile, and thus reduce the safety hazards of the equipment.

[0016] 2. The utility model moves the chuck body downward, and since the counterweight block contacts the top of the pipe pile, the counterweight block will continue to move upward as the chuck body continues to move downward until the counterweight block contacts the first trigger switch. Since the first trigger switch is electrically connected to the chuck body, at this time, the first trigger switch will drive the two clamping plates to clamp the pipe pile through the chuck body, thereby facilitating the processing of the pipe pile. During this period, the first trigger switch will delay the power supply of the electromagnetic strip. After the processing of the pipe pile is completed, the first trigger switch will turn on the power supply of the electromagnetic strip, and the pipe pile will be clamped after the clamping plate completely enters the inner cavity of the pipe pile, which can improve the fixing effect of the equipment on the pipe pile, thereby facilitating the further processing of the pipe pile by the equipment.

This is a prior art and will not be described in detail here; one end of the chuck body 2 away from the clamping plate 3 is fixedly connected with a flange 1, and the flange 1 is used to fix the chuck body 2 and the vibratory hammer.

[0032] An inner groove 4 is provided at the center of the bottom end of the chuck body 2, an outer sleeve 41 is fixedly connected to the inner wall of the inner groove 4, a plurality of inner sleeves 42 are elastically and slidably connected to the inner cavity of the outer sleeve 41, and a counterweight 43 is fixedly connected to the end of the inner sleeve 42 away from the outer sleeve 41.

[0033] An extrusion block 44 is slidably connected to the inner cavity of the outer sleeve 41 and at a side away from the inner sleeve 42 , and a first trigger switch 45 matched with the extrusion block 44 is fixedly connected to the inner cavity of the outer sleeve 41 .

[0034] The inner cavity of the chuck body 2 is provided with a receiving groove 436 that matches the counterweight block 43, and the receiving groove 436 is connected to the inner groove 4. The inner cavity of the counterweight block 43 is symmetrically provided with two rectangular grooves 431. The inner wall of the rectangular groove 431 is fixedly connected with a connecting block 432. The inner cavity of the rectangular groove 431 is slidably connected with a limiting block 433. The inner cavity of the chuck body 2 is provided with a limiting groove 437 that matches the limiting block 433. The limiting groove 437 is connected to the inner cavity of the receiving groove 436, and the connecting block 432 is away from A compression spring 434 is fixedly connected to one side of the inner wall of the rectangular groove 431, and the side of the compression spring 434 away from the connecting block 432 is fixedly connected to the limit block 433, and the inner cavities of the limit block 433 and the connecting block 432 are both embedded with electromagnetic strips 435, and the two electromagnetic strips 435 have opposite magnetic poles on the sides facing each other, and the two electromagnetic strips 435 attract each other after being energized; the inner cavity of the counterweight block 43 is filled with magnetic shielding material, thereby preventing the magnetism of the electromagnetic strip 435 from affecting the operation of the chuck body 2.

[0035] The clamp body 2 and the two electromagnetic strips 435 are electrically connected to the first trigger switch 45 .

[0036] A side groove 51 is provided on the side away from each other of the two clamping plates 3, and two supporting springs 52 are symmetrically fixedly connected to the inner wall of the side groove 51. A detection plate 5 fixedly connected to the supporting spring 52 is slidably connected to the inner cavity of the side groove 51, and the inclination of the detection plate 5 is equal to the inclination of the clamping plate 3. A stop block 54 is fixedly connected to the side of the detection plate 5 close to the inner wall of the side groove 51, and a soft pad 53 is fixedly installed on the side of the detection plate 5 away from the inner wall of the side groove 51. A second trigger switch 55 matching the stop block 54 is fixedly installed on the inner wall of the side groove 51, and an alarm 56 electrically connected to the second trigger switch 55 is fixedly installed on the side wall of the chuck body 2.

[0037] When the utility model is in use, the equipment is fixed to the vibrating hammer through the flange 1. After the two are fixed, the multiple inner sleeves 42 in the inner cavity of the outer sleeve 41 are extended from the inner cavity of the outer sleeve 41 through the action of the counterweight block 43. Before the chuck body 2 is moved down, the counterweight block 43 is made to contact with the top of the pipe pile, and then the chuck body 2 is moved down. During the downward movement of the chuck body 2, the detection plates 5 on the two clamping plates 3 are used to detect the inner diameter of the pipe pile. When the inner diameter of the pipe pile meets the requirements, the two clamping plates 3 will move down smoothly. When they do not meet the requirements, the detection plates 5 will squeeze the supporting springs 52 in the inner cavity of the clamping plates 3 and make the supporting springs 52 elastically deformed. At the same time, as the detection plate 5 continues to slide, the abutment block 54 on it will contact the second trigger switch 55. At this time, the alarm 56 will sound an alarm, which is convenient for the staff to deal with it in time.

[0038] As the chuck body 2 continuously moves downward, the counterweight 43 continuously moves upward. During the upward movement of the counterweight 43, multiple inner sleeves 42 will enter the inner cavity of the outer sleeve 41 in sequence. When all the inner sleeves 42 enter the inner cavity of the outer sleeve 41, the counterweight 43 will enter the receiving groove 436 of the chuck body 2. The elastic force of the spring 434 in the inner cavity of the counterweight 43 causes the limit block 433 to enter the inner cavity of the corresponding limit groove 437, thereby facilitating the limit of the counterweight 43 to prevent it from affecting the subsequent clamping work of the clamping plate 3.

[0039] When all the inner sleeves 42 enter the inner cavity of the outer sleeve 41, the inner sleeve 42 will squeeze the extrusion block 44. When the extrusion block 44 is squeezed, it will contact the first trigger switch 45. Since the first trigger switch 45 is electrically connected to the chuck body 2, at this time, the first trigger switch 45 will drive the two clamping plates 3 to clamp the pipe pile through the chuck body 2, thereby facilitating the processing of the pipe pile. During this period, the first trigger switch 45 will delay the power supply of the electromagnetic strip 435. After the processing of the pipe pile is completed, the first trigger switch 45 will turn on the power supply of the electromagnetic strip 435, and the mutual attraction of the electromagnetic strip 435 will release the limit of the counterweight block 43, thereby facilitating the continuous use of the equipment.
