The internal shaft disassembly device provided in one embodiment of the present application comprises a supporting gantry 10, a connecting top rod 20 and a disassembly gantry 30. The connecting top rod 20 is arranged on the supporting gantry 10, and the lower end of the connecting top rod 20 is connected to the disassembly gantry 30. The disassembly gantry 30 comprises a fixing splint 40, and the fixing splint 40 is connected to the internal shaft to be disassembled.

[0038] When it is necessary to disassemble the built-in shafts on the equipment, the support gantry 10 is placed above the built-in shafts to be disassembled, and the support rods of the support gantry 10 are against the surface of the equipment. The connecting push rod 20 is driven to make the disassembly gantry 30 descend to the corresponding height of the inner side of the outer end of the built-in shaft, and the position of the fixed clamping plate 40 of the disassembly gantry 30 is adjusted so that the fixed clamping plate 40 is against the inner side of the outer end of the built-in shaft to be disassembled. The connecting push rod 20 is driven again to make the disassembly gantry 30 move along the axial direction of the connecting push rod 20, and the disassembly gantry 30 applies a thrust to the outer end of the built-in shaft to be disassembled through the fixed clamping plate 40, and gradually pulls the built-in shaft to be disassembled out of the equipment.

[0039] The above-mentioned built-in shaft disassembly device, by setting a supporting gantry 10, can select or adjust the supporting gantry 10 based on the surface flatness of the equipment where the embedded shafts to be disassembled are located, thereby improving the application scope of the disassembly device, and the disassembly gantry 30 is connected to the supporting gantry 10 by means of the connecting top rod 20, and the connecting top rod 20 drives the disassembly gantry 30 to move along the axial direction of the connecting top rod 20, and a fixed splint 40 is provided on the disassembly gantry 30, and the fixed splint 40 is connected to the built-in shaft to be disassembled, and the outer end of the built-in shaft to be disassembled is supported by the fixed splint 40 and the built-in shaft to be disassembled is pushed when the connecting top rod 20 moves axially, thereby avoiding the fixed splint 40 and the built-in shaft to be disassembled from falling off, and avoiding damage to the built-in shaft to be disassembled, thereby improving the operability of the disassembly of the built-in shaft, and improving the disassembly quality of the built-in shaft to be disassembled.

[0040] Combination Figure 2 As shown, Figure 2 The structural schematic diagram of the support gantry 10 in an embodiment of the present application is shown. In an exemplary embodiment, the support gantry 10 includes a vertical support rod 110 and a transverse support rod 120, and the end of the transverse support rod 120 is inserted into the upper end of the vertical support rod 110. The upper end of the vertical support rod 110 is provided with a first fixing screw 130, and the first fixing screw 130 abuts against the transverse support rod 120.

[0041] When it is necessary to disassemble the built-in shaft on the equipment, observe the surface flatness of the built-in shaft to be disassembled. Based on the surface flatness of the built-in shaft to be disassembled, adjust the position of the vertical support rod 110, that is, move the vertical support rod 110 along the axial direction of the transverse support rod 120 until the vertical support rod 110 can resist the relatively flat surface near the built-in shaft to be disassembled, and tighten the first fixing screw 130 so that the vertical support rod 110 cannot move along the axial direction of the transverse support rod 120.

[0042] Then, place the adjusted support gantry 10 against a relatively flat surface near the built-in shaft to be disassembled, move the connecting push rod 20 along the axial direction, and drive the connected disassembly gantry 30 to move to the corresponding height inside the outer end of the built-in shaft. Adjust the position of the fixed clamp 40 of the disassembly gantry 30 so that the fixed clamp 40 presses against the inner side of the outer end of the built-in shaft to be disassembled. Drive the connecting push rod 20 again so that the disassembly gantry 30 moves along the axial direction of the connecting push rod 20, and the disassembly gantry 30 applies a thrust to the outer end of the built-in shaft to be disassembled through the fixed clamp 40, and gradually pulls the built-in shaft to be disassembled out of the equipment.

[0043] In this embodiment, the relative positions of the vertical support rods 110 and the transverse support rods 120 can be adjusted according to the flatness of the surface of the embedded shafts of the equipment to be disassembled, so that the support gantry 10 can better adapt to the characteristics of the surfaces of different equipment, ensure stable support and provide reliable disassembly support, provide greater convenience for the disassembly operation, and significantly improve the adaptability and flexibility of the support gantry 10, thereby expanding its scope of application in the disassembly device.

[0044] Continue reading Figure 1 and Figure 2 In an exemplary embodiment, the vertical support rod 110 includes a vertical fixed support rod 111 and a vertical adjustment screw rod 112, and the upper end of the vertical fixed support rod 111 is connected to the end of the horizontal support rod 120. The vertical fixed support rod 111 is provided with an adjustment groove, and the vertical adjustment screw rod 112 is embedded in the adjustment groove. The inner side wall of the adjustment groove is provided with a threaded section, and the thread of the threaded section matches the thread of the vertical adjustment screw rod 112.

[0045] In order to adapt to built-in shafts in different environments, the vertical support rod 110 supporting the gantry 10 is set to a telescopic structure, such as the structure of the vertical fixed support rod 111 and the vertical adjustment screw 112 in this embodiment. A slot is opened axially inward from the lower end of the vertical fixed support rod 111, and the inner wall of the slot is threaded to obtain an adjustment groove. In one embodiment, a gasket is connected to the lower end of the vertical adjustment screw 112, and the gasket abuts against the surface of the equipment when the built-in shaft to be disassembled is disassembled. Optionally, the surface of the gasket abutting against the surface of the equipment is provided with an anti-slip layer.

[0046] When the embedded section length of the built-in shaft to be disassembled is greater than the vertical fixed support rod 111, the vertical adjustment screw 112 is rotated to move the vertical adjustment screw 112 outward along the axial direction of the vertical support rod 110 until the length of the vertical support rod 110 is greater than the embedded section length of the built-in shaft to be disassembled.

[0047] Then observe the surface flatness of the built-in shaft to be disassembled. Based on the surface flatness of the built-in shaft to be disassembled, adjust the position of the vertical support rod 110, that is, move the vertical support rod 110 along the axial direction of the transverse support rod 120 until the vertical support rod 110 can resist the relatively flat surface near the built-in shaft to be disassembled.

[0048] This facilitates the disassembly operation of the built-in shafts to be disassembled by utilizing the connecting screw rods and the disassembly gantry 30 .

[0049] Continue reading Figure 1 and Figure 2The lateral support rod 120 includes a connecting through hole 140 and a first adjustment limit groove 150, and the connecting top rod 20 is inserted into the connecting through hole 140. The first fixing screw 130 provided at the upper end of the vertical support rod 110 is embedded in the first adjustment phase groove, and the end of the first fixing screw 130 can abut against the first adjustment limit groove 150. Optionally, an anti-slip layer is provided at the end of the first fixing screw 130. Optionally, the connecting through hole 140 and the connecting top rod 20 are threadedly connected.

[0050] After observing the surface flatness of the installation location of the built-in shaft to be disassembled, if the spacing between the vertical support rods 110 is larger than the relatively flat surface, loosen the first fixing screw 130 to make the vertical support rod 110 movable. Then move the vertical support rod 110 along the transverse fixing rod, and the first fixing screw 130 moves along the first adjustment limit groove 150. Until reaching a more suitable position, tighten the first fixing screw 130 and the first fixing screw 130 abuts against the bottom of the first adjustment limit groove 150, so that the vertical support rod 110 and the transverse support rod 120 are in an immobile state.

[0051] Combination Figure 3 As shown, Figure 3 The schematic diagram of the structure of the disassembly gantry 30 in one embodiment of the present application is shown. In some embodiments, the disassembly gantry 30 further includes a disassembly support rod 310 and a disassembly clamping arm 320. The fixing clamping plate 40 is arranged at the lower end of the disassembly clamping arm 320. The disassembly clamping arm 320 is arranged on the disassembly support rod 310. The end of the disassembly support rod 310 passes through the upper end of the disassembly clamping arm 320. The upper end of the disassembly clamping arm 320 is provided with a second fixing screw 330, and the second fixing screw 330 abuts against the disassembly support rod 310.

[0052] When it is necessary to disassemble the built-in shaft on the equipment, observe the gap distance between the built-in shaft to be disassembled and the surface of the equipment, consider the thickness of the fixed clamping plate 40 connected to the current disassembly clamping arm 320, and analyze whether the fixed clamping plate 40 can be embedded in the observed gap distance.

[0053] If the fixed clamp plate 40 connected to the current disassembly clamp arm 320 cannot be embedded in the observed gap spacing, loosen the second fixing screw 330, move the disassembly clamp arm 320 connected to the disassembly support rod 310 outward along the axial direction of the disassembly support rod 310, and replace the disassembly clamp arm 320 connected to the fixed clamp plate 40 that can be embedded in the gap spacing.

The cross-sectional diameter of the connecting section 210 of the connecting mandrel 20 is larger than the cross-sectional diameter of the fixing rod of the connecting mandrel 20.

[0056] When the disassembly gantry 30 needs to be replaced, the bushing bearing 230 is removed from the fixed section 220 of the connecting mandrel 20 , and then the disassembly gantry 30 is moved along the axial direction of the fixed section 220 until the disassembly gantry 30 is separated from the connecting mandrel 20 .

[0057] In one embodiment, the disassembly support rod 310 further includes a second adjustment limit groove 350, and the second fixing screw 330 provided at the upper end of the disassembly clamping arm 320 is embedded in the second adjustment limit groove 350, and the end of the second fixing screw 330 can abut against the second adjustment limit groove 350.

[0058] When the supporting gantry 10 is against the surface of the equipment, loosen the second fixing screw 330 to make the disassembly clamping arm 320 movable, and move the disassembly clamping arm 320 along the axial direction of the disassembly support rod 310 until the distance between the fixed clamping plates 40 connected to the disassembly clamping arm 320 is larger than the cross-sectional width of the built-in shaft to be disassembled, and then tighten the second fixing screw 330 to prevent the disassembly clamping arm 320 from moving.

[0059] The connecting push rod 20 is driven to move the disassembly gantry 30 downward until the disassembly gantry 30 is lowered to the height corresponding to the inner side of the outer end of the built-in shaft. The second fixing screw 330 is loosened to make the disassembly clamping arm 320 movable, and the disassembly clamping arm 320 is moved along the axial direction of the disassembly support rod 310, so that the distance between the fixed clamping plates 40 connected to the disassembly clamping arm 320 is smaller than the cross-sectional width of the built-in shaft to be disassembled, and then the second fixing screw 330 is tightened to make the disassembly clamping arm 320 immovable.

[0060] The connecting rod 20 is driven again, so that the disassembly gantry 30 moves axially along the connecting rod 20, and the disassembly gantry 30 applies a thrust to the outer end of the built-in shaft to be disassembled through the fixed clamp 40, gradually pulling the built-in shaft to be disassembled out of the equipment.

Optionally, the end of the second fixing screw 330 is provided with an anti-slip layer.

[0065] When disassembling the built-in shaft, when it is necessary to disassemble the built-in shaft on the equipment, observe the gap between the built-in shaft to be disassembled and the surface of the equipment, consider the thickness of the fixed clamping plate 40 connected to the current disassembly clamping arm 320, and analyze whether the fixed clamping plate 40 can be embedded in the observed gap. If the fixed clamping plate 40 connected to the current disassembly clamping arm 320 cannot be embedded in the observed gap, loosen the second fixing screw 330, move the disassembly clamping arm 320 connected to the disassembly support rod 310 outward along the axial direction of the disassembly support rod 310, and replace the disassembly clamping arm 320 connected to the fixed clamping plate 40 that can be embedded in the gap.

[0066] Then, the embedded length of the built-in shaft to be disassembled is known and compared with the vertical fixed support rod 111. When the embedded length of the built-in shaft to be disassembled is greater than the vertical fixed support rod 111, the vertical adjustment screw 112 is rotated so that the vertical adjustment screw 112 moves outward along the axial direction of the vertical support rod 110 until the length of the vertical support rod 110 is greater than the embedded length of the built-in shaft to be disassembled.

[0068] Then, loosen the second fixing screw 330 so that the disassembly clamping arm 320 is in a movable state, and move the disassembly clamping arm 320 along the axial direction of the disassembly support rod 310 until the spacing between the fixed clamping plates 40 connected to the disassembly clamping arm 320 is greater than the cross-sectional width of the built-in shaft to be disassembled, and then tighten the second fixing screw 330 to make the disassembly clamping arm 320 unable to move. Drive the connecting push rod 20 to move the disassembly gantry 30 downward until the disassembly gantry 30 drops to the corresponding height inside the outer end of the built-in shaft.
