Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 As shown:

[0028] A pile driving hydraulic hammer comprises a fixing frame 1 and a hydraulic hammer 2 installed on the surface of the fixing frame 1.

[0029] In this embodiment: the existing public (announcement) number: CN213773362U discloses a high-efficiency hydraulic hammer pile driver with a buffer mechanism; in order to solve the technical problems existing in this prior art, such as the above background technology disclosure that "in the process of pile driving of anchor piles, the anchor piles will be skewed due to loose soil and other reasons, and the existing pile hammers do not have the function of detecting the degree of skewness of the anchor piles. If the anchor piles are found to be skewed during the pile driving process, it will affect the subsequent acceptance work". In combination with use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a hammer assembly 3 and an installation assembly 4 are added to the application document.

[0030] More specifically:

[0031] like Figure 1-Figure 4 As shown:

[0032] In combination with the above content, the hammer assembly 3 includes a slide rail 35 symmetrically fixedly connected to the surface of the fixed frame 1 and a limit block 36 slidably connected to the surface of the slide rail 35, and the interior of the limit block 36 is provided with connecting rods 312 in a ring array, and the adjacent end of the connecting rod 312 is fixedly connected to the first clamping plate 39, and the other end of the connecting rod 312 is fixedly connected to the moving block 310, and a moving groove is provided on the side of the limit block 36 close to the moving block 310, and an electric push rod 314 is fixedly installed on the side of the moving block 310 close to the moving block 310, and the output end of the electric push rod 314 is fixedly connected to the alarm switch 313.

[0033] In the present embodiment: when the pile driving hydraulic hammer is in use, the multiple groups of first clamps 39 are driven to open by pulling the moving block 310, and then the first clamps 39 are fixed to the top of the anchor pile, and the hydraulic hammer 2 pushes the hammer head 31 to hammer the anchor pile. During the hammering process, the first clamp 39 is pressed against the anchor pile by the elastic force of the second spring 311. When the anchor pile is tilted, the anchor pile will push the moving block 310 through the connecting rod 312 to squeeze the alarm switch 313, and the alarm switch 313 will sound an alarm, so as to remind the staff to adjust the anchor pile in time. By starting the electric push rod 314, the position of the alarm switch 313 can be adjusted, so as to sound an alarm when the anchor pile is tilted to different degrees.

[0034] Going further:

[0035] like Figure 1-Figure 4 As shown:

[0036] In order to facilitate the hammering of the anchor pile, in an optional embodiment: a second spring 311 is sleeved on the surface of the connecting rod 312, and the second spring 311 is fixedly connected between the first clamping plate 39 and the limit block 36; a fixed block 33 is fixedly connected to one side of the hydraulic hammer 2, and the fixed block 33 is slidably connected to the surface of the slide rail 35, a first screw rod 34 is screwed to one side of the inside of the hammer assembly 3, and the first screw rod 34 is rotatably connected to the inside of the fixed frame 1 through a bearing; a motor 32 is fixedly installed on the top of the fixed frame 1, and the output end of the motor 32 is fixedly connected to the first screw rod 34; a hammer rod 37 is fixedly connected to the output end of the hydraulic hammer 2, a hammer head 31 is installed at the bottom end of the hammer rod 37, a movable groove is opened on the side of the hammer head 31 close to the hammer rod 37, and a first spring 38 is fixedly connected between the hammer rod 37 and the hammer head 31.

[0037] In this embodiment: when it is necessary to drive the anchor pile, first, the first screw rod 34 is driven to rotate by starting the motor 32, and then the fixed block 33 is driven to move, the height of the hydraulic hammer 2 is adjusted, and the moving block 310 is pulled to drive multiple groups of first clamps 39 to open, and then the first clamps 39 are fixed to the top of the anchor pile, and then the hydraulic hammer 2 is started to push the hammer head 31 to hammer the top of the anchor pile through the hammer rod 37. During the hammering process, the first clamp 39 is pressed against the anchor pile by the elastic force of the second spring 311. When the anchor pile is tilted, the anchor pile will push the moving block 310 to squeeze the alarm switch 313 through the connecting rod 312, and the alarm switch 313 will sound an alarm, so as to remind the staff to adjust the anchor pile in time. At the same time, the first spring 38 can absorb and buffer the reaction impact of the anchor pile, and the hydraulic hammer 2 is driven by the motor 32 to move vertically, so as to adjust the height of the hydraulic hammer 2 according to the driving depth of the anchor pile.

[0038] It should be noted that the motor 32, the hydraulic hammer 2, the alarm switch 313 and the electric push rod 314 are electrically connected to the external power supply through wires, and the alarm switch 313 is connected to the external alarm device, so that the alarm can be activated through the alarm switch 313 to remind the staff to adjust the anchor pile in time.

[0039] More specifically:

[0041] In combination with the above content, the bottom end of the fixing frame 1 is fixedly connected with an installation component 4, and the installation component 4 includes a mounting block 41 fixedly connected to the bottom end of the fixing frame 1, a second screw 45 screwed in a circular array inside the mounting block 41, and a second clamping plate 44 rotatably connected to one end of the second screw 45, and a roller 42 is rotatably connected inside the second clamping plate 44; the second clamping plate 44 is symmetrically fixedly connected to a limiting rod 43 on one side close to the mounting block 41, and a sliding groove is provided on one side of the mounting block 41 close to the limiting rod 43, and the bottom end of the limiting block 36 is fixedly connected with a base 46.

[0042] In this embodiment: when installing the anchor pile, the anchor pile is inserted between multiple groups of second clamping plates 44, and then the second screw 45 is rotated to push the second clamping plate 44 so that the roller 42 is in close contact with the surface of the anchor pile, and the anchor pile is limitedly supported. During the piling process, the anchor pile will slide on the surface of the roller 42, thereby increasing the stability of the anchor pile driving.

[0043] Working principle: When the anchor pile needs to be driven, first move the fixing frame 1 to move the mounting block 41 to the driving area, then start the motor 32 to drive the first screw 34 to rotate, and then drive the fixing block 33 to move, adjust the height of the hydraulic hammer 2, then insert the anchor pile between the multiple sets of second clamping plates 44, and rotate the second screw 45 to push the second clamping plates 44 so that the roller 42 is close to the surface of the anchor pile, and the anchor pile is limited and supported, and then the limit block 36 is moved to the top of the anchor pile, and the moving block 310 is pulled to drive the multiple sets of first clamping plates 39 to open, and the first clamping plates 39 are fixed to the top of the anchor pile, and then Start the hydraulic hammer 2 and push the hammer head 31 through the hammer rod 37 to hammer the top of the anchor pile. During the hammering process, the first clamping plate 39 is pressed against the anchor pile by the elastic force of the second spring 311. When the anchor pile is tilted, the anchor pile will push the moving block 310 through the connecting rod 312 to squeeze the alarm switch 313. The alarm switch 313 will sound an alarm, which is convenient for reminding the staff to adjust the anchor pile in time. At the same time, the first spring 38 can absorb and buffer the reaction impact of the anchor pile, and the motor 32 can drive the hydraulic hammer 2 to move vertically, so that the height of the hydraulic hammer 2 can be adjusted according to the driving depth of the anchor pile.
