The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0026] The hydraulic disassembly device according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0027] like Figure 1-3 As shown, the hydraulic disassembly device according to the embodiment of the utility model includes a mounting seat 1, a driving assembly 2 and a push rod 3.

[0028] The mounting seat 1 is suitable for being arranged on the device to be disassembled. Figure 1 As shown, the mounting seat 1 is detachably fixed on the device that needs to be disassembled.

[0029] The drive assembly 2 includes an outer shell 21 and an inner shell 22. One of the outer shell 21 and the inner shell 22 is connected to the mounting base 1. At least a portion of the inner shell 22 is disposed inside the outer shell 21 and is disposed relative to the outer shell 21 along the length direction of the outer shell 21 (e.g., Figure 1-3 The outer shell 21 and the inner shell 22 are movable in the left and right directions as shown, and at least a portion of the outer shell 21 and the inner shell 22 are spaced apart in the inner and outer directions to form a sealed cavity 23 into which hydraulic oil can flow. The drive assembly 2 has a first state and a second state. In the first state, hydraulic oil flows into the sealed cavity 23 to make the inner shell 22 and the outer shell 21 move away from each other. In the second state, hydraulic oil flows out of the sealed cavity 23 to make the inner shell 22 and the outer shell 21 move closer to each other. Specifically, as Figure 2 and Figure 3 As shown, the right end of the inner shell 22 is inserted into the left end of the outer shell 21, and the outer circumference of the right end of the inner shell 22 and the inner circumference of the left end of the outer shell 21 are spaced apart to form a sealed cavity 23. Figure 2 As shown, in the first state, hydraulic oil is introduced into the sealing chamber 23, and the inner shell 22 and the outer shell 21 are separated from each other to extend the drive assembly 2, as shown in FIG. Figure 3 As shown, in the second state, the hydraulic oil in the sealing chamber 23 can be pumped out of the sealing chamber 23, and the inner housing 22 and the outer housing 21 are close to each other to shorten the drive assembly 2.

[0030] The push rod 3 is connected to the other of the outer shell 21 and the inner shell 22 so that the other of the outer shell 21 and the inner shell 22 drives the push rod 3 to move. Figure 1 As shown, the arrangement of the outer shell 21 and the inner shell 22 can be arranged according to actual conditions, for example: the outer shell 21 can be fixed on the mounting seat 1, and the push rod 3 is fixed on the left end of the inner shell 22, or the left end portion of the inner shell 22 can be fixed on the mounting seat 1, and the push rod 3 fixes the right end of the outer shell 21. Thus, in the first state, the free end of the push rod 3 is aligned with the parts (pins, bearings, gear parts, etc.) that need to be disassembled, and the drive assembly 2 is extended so that the push rod 3 pushes the components to disassemble the parts. In the second state, the drive assembly 2 is shortened to recover the push rod 3.

[0031] The hydraulic disassembly device 100 of the embodiment of the utility model is provided with a mounting seat 1, a driving assembly 2 and a push rod 3. The driving assembly 2 is hydraulically driven to push the push rod 3 to push the parts out of the device through hydraulic drive, thereby disassembling the parts. Compared with the related art, the disassembly efficiency is high and the disassembly strength is low. In certain extreme conditions of the high-risk industry in coal mines, unnecessary damage to the parts can be avoided, and the labor intensity of the workers can be greatly reduced.

[0032] In some embodiments, the hydraulic disassembly device 100 further includes an oil tank (not shown in the figure) and an oil pump (not shown in the figure).

[0033] Hydraulic oil is stored in the oil tank, which is arranged on the mounting base 1. Specifically, the oil tank can be arranged according to actual conditions, for example, the oil tank can be arranged on the mounting base 1 or on the ground outside the mounting base 1, and hydraulic oil is stored in the oil tank.

[0034] The two ends of the oil pump are respectively connected with the oil tank and the sealed cavity 23, so that the hydraulic oil flows through the oil pump in the oil tank and the sealed cavity 23. Specifically, the oil pump can be fixedly mounted on the mounting base 1, or can be mounted on the ground outside the mounting base 1. The oil pump is respectively connected with the oil tank and the sealed cavity 23 through the oil pipe. In the first state, the oil pump pumps the hydraulic oil in the oil tank into the sealed cavity 23. In the second state, the oil pump pumps the hydraulic oil in the sealed cavity 23 into the oil tank, thereby supplying oil to the drive device through the oil tank and the oil pump.

[0035] In some embodiments, the housing 21 is provided with an oil inlet 211 and an oil outlet 212, both of which are connected to the sealed cavity 23. In the first state, the sealed cavity 23 is supplied with oil through the oil inlet 211, and in the second state, the hydraulic oil in the sealed cavity 23 is discharged through the oil outlet 212. Specifically, Figure 2-3 As shown, the right end face of the housing 21 is provided with an oil inlet hole 211 and an oil outlet hole 212 which penetrate the right end face, and the oil inlet hole 211 and the oil outlet hole 212 are both connected to the sealing cavity 23, thereby, oil is supplied to the sealing cavity 23 or the oil in the sealing cavity 23 is extracted through the oil inlet hole 211 and the oil outlet hole 212 respectively.

[0036] In some embodiments, the hydraulic disassembly device 100 further includes a plug 5. In a first state, the plug 5 is disposed in the oil outlet hole 212 to block the oil outlet hole 212. In a second state, the plug 5 is disposed in the oil inlet hole 211 to block the oil outlet hole 212. Specifically, the plug 5 may be a rubber plug 5, such as Figure 2 As shown, in the first state, the plug 5 blocks the oil outlet 212. Figure 3 As shown, in the second state, the plug 5 blocks the oil inlet hole 211, and the drive assembly 2 is more reasonably arranged.

[0037] In some embodiments, one end of the push rod 3 is inserted into the inner shell 22 and is detachably connected to the inner shell 22 through threaded engagement. Figure 2-3 As shown, the right end of the push rod 3 is provided with an external thread 31, and the left end of the inner shell 22 is provided with a threaded through hole. The push rod 3 cooperates with the inner shell 22 through the external thread 31 and the threaded through hole so that the push rod 3 can be detachably installed on the inner shell 22.

[0038] In some embodiments, the hydraulic disassembly device 100 further includes a plurality of push rods 3 and a storage box (not shown in the figure).

[0039] Multiple push rods 3 can be connected to the inner shell 22, the lengths of any two push rods 3 are not equal, and the cross-sectional areas of the other ends of any two push rods 3 are not equal, and multiple push rods 3 are stored in the storage box. Specifically, the left ends of multiple push rods 3 can be detachably connected to the inner shell 22, and the lengths of multiple push rods 3 are not the same, and the cross-sectional area of ​​the left end of each push rod 3 can be set according to actual conditions, for example: it can be circular, rectangular, elliptical, etc., and the cross-sectional area of ​​the left end of each push rod 3 is also uneven. Therefore, different push rods 3 can be replaced according to actual conditions to disassemble different types of parts. The storage box can be fixedly installed on the mounting seat 1, and thus, multiple push rods 3 can be stored in the storage box.

[0040] In some embodiments, the hydraulic disassembly device 100 further includes a lighting member (not shown in the figure), which is disposed on a side of the housing 21 adjacent to the push rod 3, and is used to illuminate the push rod 3. Specifically, the lighting member may be a lighting lamp, which may be disposed at the left end of the housing 21, so that the left end of the push rod 3 can be illuminated by the lighting member, so that the push rod 3 can be aligned with the parts to disassemble the parts.

[0041] In some embodiments, the hydraulic disassembly device 100 further includes an anti-skid pad (not shown in the figure), which is arranged on the lower end surface of the mounting seat 1. Specifically, the anti-skid pad can be a rubber anti-skid pad and is fixed on the lower end surface of the mounting seat 1, thereby improving the stability of the mounting seat 1 on the device to be disassembled by the anti-skid pad, thereby improving the stability of the hydraulic disassembly device 100 in disassembling parts.

[0042] In some embodiments, the hydraulic disassembly device 100 further includes a sealing ring 4, which is sleeved on the outer circumference of the inner shell 22 and fits with the inner circumference of the outer shell 21 to seal the sealing cavity 23. Figure 2-3 As shown, the sealing ring 4 is sleeved on the left end of the inner shell 22, and the outer circumference of the sealing ring 4 is in contact with the inner circumference of the outer shell 21. Therefore, when hydraulic oil flows into the sealing chamber 23, the sealing ring 4 can prevent the hydraulic oil from flowing out, thereby ensuring the sealing performance of the sealing chamber 23.

[0043] In some embodiments, the drive assembly 2 may be a hydraulic nut. Thus, by supplying or discharging oil to the hydraulic nut, the hydraulic nut is extended or shortened, thereby making the drive assembly 2 more reasonably arranged.

[0044] It is worth noting that the hydraulic nut is a device that uses liquid pressure to achieve screw connection, which is composed of a threaded sleeve, a piston, a sealing ring, a pressure plate and other components. When the liquid flows into the hydraulic nut through the inlet pipe, the piston will be pressed by the liquid and move downward, so that the pressure plate exerts force downward to form a tight connection with the connected parts. The sleeve is fixed on the mounting seat 1, and the piston is connected to the push rod 3. Thus, the push rod moves through the relative movement between the piston and the sleeve. The mounting seat 1 can be installed on the device that needs to be disassembled through a clamp, which is not described in detail in the embodiment of the utility model.
