Method used

A deep-hole compaction hammer removal device was designed, comprising a base, a bracket, a telescopic hydraulic cylinder, and a release mechanism. The telescopic hydraulic cylinder drives the release mechanism to move, and combined with a servo motor and a unidirectional lateral lead screw, it enables flexible position adjustment and hoisting, thereby enhancing the hammer removal capability.

Benefits of technology

It effectively solved the problem of difficulty in pulling out hammers from deep boreholes, improved construction efficiency and flexibility, and enhanced construction capabilities.

Description

Technical Field

[0001] This utility model relates to a hammer-pulling device, specifically a deep-hole dynamic compaction hammer-pulling device. Background Technology

[0002] Existing deep borehole dynamic compaction hammer extraction devices mainly consist of gantry-mounted dynamic compaction machines. However, since the hammer length in deep borehole dynamic compaction reaches 9-15m, relying solely on the extraction force of the dynamic compaction machine often leads to difficulties in hammer extraction, forcing construction to be interrupted. Alternatively, increasing the pulley system ratio of the dynamic compaction machine can improve hammer extraction capacity, but this significantly reduces the hammer lifting speed, resulting in low construction efficiency. By adding a matching hammer extraction device, the construction capacity and efficiency of existing deep borehole dynamic compaction can be enhanced.

[0003] In view of the above, this application designs a deep-hole dynamic compaction hammer device. Utility Model Content

[0004] The main objective of this disclosure is to provide a deep-hole compaction and hammering device to effectively solve the problems raised by the inventors in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A deep borehole compaction hammer pulling device includes a base, a support, a telescopic hydraulic cylinder, and a release device. Four supports arranged in a circular array are fixedly installed on the top of the base. A gantry frame is fixedly installed on the top of every two supports. A linear slide rail is fixedly installed between two gantry frames. A linear moving seat is movably installed on the linear slide rail. The telescopic hydraulic cylinder is fixedly installed at the bottom of the linear moving seat. The release device is connected to the output end of the telescopic hydraulic cylinder.

[0007] Preferably, the linear slide rail is provided with a linear guide rail, and the linear moving seat is slidably installed in the linear guide rail.

[0008] Preferably, a one-way transverse lead screw is rotatably installed inside the linear guide rail, the linear moving seat is threaded onto the one-way transverse lead screw, and two parallel limiting slide shafts are fixedly installed on the linear guide rail, with the limiting slide shafts being parallel to the one-way transverse lead screw. The linear moving seat is slidably sleeved on the limiting slide shafts.

[0009] Preferably, a servo motor is fixedly installed on the gantry frame, and one end of the unidirectional transverse lead screw extends to the left and is fixedly connected to the output shaft of the servo motor.

[0010] Preferably, the unhooking device includes a ring hook, a positioning block, a pin, and a stop handle. The output end of the telescopic hydraulic cylinder is fixedly connected to a mounting plate. The ring hook is fixedly connected to the mounting plate. The positioning block is fixedly connected inside the ring hook, and the stop handle is movably mounted on the positioning block via the pin.

[0011] Preferably, the size of the stop handle is smaller than the notch size of the ring hook, and the length of the stop handle is smaller than the diameter of the ring hook.

[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0013] (i) In this application, during operation, the unhooking device transmits the pulling force to the ramming hammer, and the telescopic hydraulic cylinder works to drive the unhooking device to move, thereby realizing the hammer pulling operation and solving the problem of difficulty in pulling the hammer in deep compaction in holes.

[0014] (ii) In this application, the specific position of the unhooker can be adjusted before operation. When the servo motor works, the unidirectional transverse lead screw rotates, which in turn causes the moving linear moving seat to move, so that the telescopic hydraulic cylinder and the unhooker can move. It can not only change the position for operation, but also perform hoisting, making it very flexible to use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 The present invention provides the following embodiments:

[0022] A deep borehole compaction hammer pulling device includes a base 1, a support 2, a telescopic hydraulic cylinder 3, and a release device 4. Four supports 2 arranged in a circular array are fixedly installed on the top of the base 1. A gantry frame 201 is fixedly installed on the top of every two supports 2. A linear slide rail 202 is fixedly installed between two gantry frames 201. A linear moving seat 5 is movably installed on the linear slide rail 202. The telescopic hydraulic cylinder 3 is fixedly installed at the bottom of the linear moving seat 5. The release device 4 is connected to the output end of the telescopic hydraulic cylinder 3.

[0023] Specifically, a linear guide rail is provided on the linear slide rail 202, and the linear moving seat 5 is slidably installed inside the linear guide rail.

[0024] Specifically, a one-way transverse lead screw 6 is rotatably installed inside the linear guide rail, and a linear moving seat 5 is threaded onto the one-way transverse lead screw 6. Two parallel limit sliding shafts 7 are fixedly installed on the linear guide rail, and the limit sliding shafts 7 are parallel to the one-way transverse lead screw 6. The linear moving seat 5 is slidably sleeved on the limit sliding shafts 7.

[0025] Specifically, a servo motor 8 is fixedly installed on the gantry 201, and one end of the unidirectional transverse lead screw 6 extends to the left and is fixedly connected to the output shaft of the servo motor 8.

[0026] Specifically, the unhooking device 4 includes a ring hook 10, a positioning block 11, a pin 12, and a stop handle 13. The output end of the telescopic hydraulic cylinder 3 is fixedly connected to a mounting plate 9. The ring hook 10 is fixedly connected to the mounting plate 9. The positioning block 11 is fixedly connected inside the ring hook 10. The stop handle 13 is movably mounted on the positioning block 11 through the pin 12. The size of the stop handle 13 is smaller than the notch size of the ring hook 10, and the length of the stop handle 13 is smaller than the diameter of the ring hook 10.

[0027] The specific implementation method of this embodiment is as follows: When working, the unhooking device 4 transmits the pulling force to the hammer, and the telescopic hydraulic cylinder 3 works to drive the unhooking device 4 to move, thereby realizing the hammer pulling operation and solving the problem of difficult hammer pulling in deep compaction in holes.

[0028] Furthermore, the specific position of the unhooker 4 can be adjusted before operation. When the servo motor 8 is working, the one-way transverse lead screw 6 rotates, which in turn causes the moving linear moving seat 5 to move, thereby moving the telescopic hydraulic cylinder 3 and the unhooker 4. This not only allows for changing the working position but also for hoisting, making it very flexible to use.
