DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0026] At present, the rotation of domestic mud guns relies on hydraulic cylinders to buffer the inertia of the mud gun equipment when the mud gun body reaches the rest position. The mud gun has a large impact on the hydraulic cylinder's built-in buffer structure when it moves to a standstill, which is easy to damage the hydraulic cylinder's built-in buffer structure, thereby affecting the stability of the mud gun. Therefore, an auxiliary hydraulic mud gun buffer device is set outside the column foundation of the mud gun rotation device at the rest position, see Figures 1 to 4 .
[0027] A hydraulic mud gun resetting buffer device comprises a buffer device body 2, wherein the buffer device body 2 comprises a first sleeve 3, and a second sleeve 6 which is slidably sleeved in the first sleeve 3 at one end; a buffer member 16 is provided between the first sleeve 3 and the second sleeve 6, and a space for relative sliding is provided between the first sleeve 3 and the second sleeve 6; a bolt 10 which passes through the first sleeve 3 and the second sleeve 6 is provided in the buffer device body 2, a threaded section of the bolt 10 extends out along one end of the second sleeve 6, and an adjusting nut 12 is provided on the protruding portion of the threaded section of the bolt 10.
[0028] Specifically, the first sleeve 3 is a barrel-shaped structure with an open end, including a first cylinder 4 and a first end plate 5 welded to one end of the first cylinder 4, and a threaded through hole for installing a bolt 10 is arranged at the center of the first end plate 5; the second sleeve 6 is a barrel-shaped structure with an open end, including a second cylinder 7 slidably sleeved in the first cylinder 4, and the second cylinder 7 is partially inserted in the first cylinder 4 so that the buffer 16 is pre-pressed. Another aspect of the second cylinder 7 being partially inserted in the first cylinder 4 is to allow the buffer 16 to be further compressed, that is, the second cylinder 7 can continue to slide into the first cylinder 4 so that the buffer 16 is compressed; the outer diameter of the second cylinder 7 is 3 to 5 mm smaller than the inner diameter of the first cylinder 4; a second end plate 8 is welded to the other end of the second cylinder 7, and a second end plate through hole is provided on the second end plate 8 for clearance matching with the bolt 10, and the second end plate through hole is coaxially arranged with the threaded through hole.
[0029] The buffer 16 is arranged in the second sleeve 6, and the buffer 16 is a disc spring. One end of the buffer 16 abuts against the inner side surface of the second end plate 8; a ring 9 is arranged in the first sleeve 3, and the ring 9 is a tubular structure. The ring 9 is coaxially arranged with the threaded hole; one end of the ring 9 abuts against the inner side surface of the first end plate 5, and the other end abuts against a guide plate 14; the other end of the buffer 16 abuts against the other side surface of the guide plate 14, and the guide plate 14 makes the force on the buffer 16 more uniform; the buffer 16 is pre-pressed between the guide plate 14 and the second end plate 8, and when the buffer device body 2 is impacted by the mud gun rotating device, it provides a buffering force for the mud gun rotating device, reduces the vibration of the mud gun rotating device, and avoids damage to the mud gun.
[0030] A guide plate through hole is provided in the middle of the guide plate 14, and the guide plate through hole is coaxially arranged with the threaded through hole; the bolt 10 passes through the threaded hole, the collar 9, the guide plate through hole, the buffer 16 and the second sleeve through hole in sequence, connecting the first sleeve 3, the collar 9, the guide plate 14, the buffer 16 and the second sleeve 6; and the adjusting nut 12 screwed on the other end of the bolt 10 prevents the bolt 10 from being detached from the aforementioned components.
[0031] Preferably, a gasket 13 is provided between the second end plate 8 and the adjusting nut 12 , and the gasket 13 alleviates vibration between the second end plate 8 and the adjusting nut 12 and prevents the adjusting nut 12 from loosening.
[0032] A locking nut 17 is also provided on the protruding portion of the threaded section of the bolt 10 , and the locking nut 17 is locked to the outside of the adjusting nut 12 to prevent the adjusting nut 12 from loosening.
[0033] In another embodiment of the present invention, the buffer member 16 is a cylindrical spring. Figure 5 .
[0034] An end plate fixing column 18 is provided on the inner wall of the second end plate 8, and a guide plate fixing column 19 is provided on the guide plate 14. Both ends of the cylindrical spring are respectively sleeved and fixed on the end plate fixing column 18 and the guide plate fixing column 19. The setting of the end plate fixing column 18 and the guide plate fixing column 19 prevents the cylindrical spring from being misplaced, which affects the buffering and shock absorption of the mud gun rotating device by the reset device.
[0035] The working process of the utility model is introduced below:
[0036] First, the threaded end of the bolt is passed through the first sleeve 3 , the collar 9 , the guide plate 14 , the buffer 16 and the second sleeve 6 in sequence, and the bolt cap 11 is in contact with the first end plate 5 .
[0037] Secondly, the threaded end of the bolt passes through the bolt hole reserved on the column foundation, and then the gasket 13 is put on, and the adjusting nut 12 is screwed on. The adjusting nut 12 is screwed to a suitable position so that the buffer 16 is in a pre-stressed state in the buffer device body 2 to reduce the impact of the mud gun rotating device 1 on it; then the locking nut 17 is screwed on to further prevent the adjusting nut 12 from loosening; the position of the bolt hole reserved on the column foundation is opposite to the rest position of the mud gun rotating device 1, and space is reserved inside the column foundation, so that the bolt can retreat to the reserved space inside the column foundation when it is under pressure.
[0038] Then, after the above-mentioned preparatory work is completed, when the mud gun rotating device 1 rotates around the rotation center o along the rotation direction w to the rest position, the side wall of the mud gun rotating device 1 contacts the bolt head 11 at the front end of the buffer device body 1, and the bolt head 11 is supported by the pre-pressure of the buffer member 16 to first reduce the impact of the mud gun rotating device 1; after continuing to be impacted by the mud gun rotating device 1, the bolt retreats into the reserved space inside the column foundation, and at the same time, the second cylinder 7 of the second sleeve 6 slides relatively into the first sleeve 3; the bolt head 11 presses the first end plate 5, and the first end plate 5 transmits the pressure to the buffer member 16 through the ring 9 and the guide plate 14 in turn, and the buffer member 16 further offsets the impact and vibration of the mud gun rotating device 1 through its own deformation.
[0039] Finally, when the mud gun rotating device 1 moves to the working position again, the buffer device body 2 returns to the initial state.
[0040] The utility model protects the internal structure of the device body well through the design of the first sleeve 3 and the second sleeve 6; the design of the buffer 16 enables the device body to better offset the impact and vibration of the mud gun rotating device 1; and the device has a simple structure and good application value.
[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
