Description

Technical Field

[0001] This invention belongs to the field of fastener disassembly technology, specifically a vibration and impact disassembly device for mechanically corroded fasteners of hydraulic supports. Background Technology

[0002] After a certain period of use, the fasteners on hydraulic supports are affected by the environment and rust. Especially in the maintenance of mining machinery and heavy machinery, it is necessary to remove, maintain and replace the rusted fasteners in a timely manner. However, the rusted fasteners are difficult to remove from the supports.

[0003] In the existing technology, the disassembly of rusted fasteners on hydraulic supports is usually done manually by hammering them in the opposite direction of rotation. However, for fasteners on mining and heavy machinery, which are large in size and have a large locking area, manual hammering is difficult. The dust and rust particles generated during hammering can be easily inhaled by the operator, creating a harsh disassembly environment. Furthermore, when disassembling multiple sets of fasteners, the actual disassembly efficiency is low, the effect is poor, and the performance is unsatisfactory. Summary of the Invention

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention utilizes the rotation of a power component to control the repeated compression of an outer surrounding hydraulic component. Through hydraulic guidance via a connecting part and a deflection distribution component, hydraulic pressure is applied to the impact component. Repeated hydraulic changes control the repeated extension and retraction of the impact component, impacting and vibrating the outer surface of the corroded fastener to achieve disassembly and detachment. Simultaneously, the control unit, in conjunction with the inner and outer gear rings, controls the forward and reverse rotation of the deflection distribution component, changing the impact direction of the impact component. Through repeated impacts in both directions, the fastener is effectively disassembled and detached, removing it from its corroded state and allowing it to loosen automatically along the connecting screw. With the aid of an auxiliary unscrewing device, this invention enables quick and effective disassembly and detachment of corroded fasteners on hydraulic supports, significantly improving maintenance, replacement, and usage efficiency.

[0018] 2. This invention utilizes the hydraulic control effect of the power component on the hydraulic component again. After opening the solenoid valve in the lubrication component, the repeated compression effect in the hydraulic component guides part of the hydraulic pressure to the hydraulic pipe. This hydraulic pressure acts on the push rod two, causing the push rod two to drive the extrusion plate to reciprocate in the appropriate assembly. During the extrusion process, the lubricating oil in the lubrication component is squeezed out and sprayed out. With the inclined downward oil spray pipe and oil spray slit, the oil is sprayed towards the fastener to avoid spraying lubricating oil. The lubricating oil penetrates into the installation gap of the fastener to further achieve lubrication treatment, which helps to improve the disassembly and loosening effect, and actually greatly improves the disassembly effect.

[0019] 3. This invention utilizes the rotation effect of the power component to control the hydraulic state in the hydraulic component, thereby achieving repeated impact vibration of the impact component. This further drives the blowing component towards the fastener, using the axial flow generated by the rotation to blow air towards the fastener. This prevents dust from directly spreading to the operator's face during the impact vibration process. The active airflow changes the direction of dust flight and directly blows air onto the front of the fastener, cleaning up rust fragments generated and attached during the impact vibration, thus improving the impact dismantling effect.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 10As shown, this embodiment of the invention provides a vibration and impact dismantling device for mechanically corroded fasteners of hydraulic supports, including a support cylinder 1. An internal toothed ring 2 is rotatably sleeved inside the support cylinder 1, and an external toothed ring 3 is fixedly sleeved on the outer surface of the internal toothed ring 2. A deflection distribution component 5 is provided on the inner wall of the support cylinder 1, and an impact component 6 is fixedly provided on the side of the deflection distribution component 5. A connecting portion 7 is fixedly provided at the top of the support cylinder 1, and a hydraulic component 8 is fixedly connected to the top of the connecting portion 7. A power component 9 is provided at the top of the support cylinder 1. The power component 9 controls the hydraulic component 8 to repeatedly compress, and the internal toothed ring 2 controls the deflection of the meshing deflection distribution component 5.

[0033] The deflection distribution assembly 5 includes a rotating shaft 51, a support plate 52, a gear 53, a guide tube 54, a curved tube 55, and a curved hole 56. The rotating shaft 51 is rotatably sleeved in the support plate 52, and the support plate 52 is fixed on the inner wall of the support cylinder 1. The gear 53 is fixedly sleeved on the outer surface of the rotating shaft 51 and meshes with the internal gear ring 2. The deflection distribution assembly 5 enables the impact assembly 6 to communicate with the connecting part 7.

[0034] Example 1: In use, the device is placed on the outside of the treated fastener, allowing the support cylinder 1 to contact the front of the bracket, keeping the impact component 6 on the outside of the fastener. The control unit 4 is activated, causing it to rotate the meshing external gear ring 3, simultaneously rotating the internal gear ring 2. The internal gear ring 2 rotates, driving the deflection distribution component 5 to rotate. As gear 53 follows the internal gear ring 2 in rotation, it drives the impact component 6 to deflect via the rotating shaft 51 and curved tube 55, causing the impact component 6 to tilt towards the outer side of the fastener. The three sets of distributed impact components 6 deflect synchronously. The power component 9 is activated, and motor 91 drives cam 92 to rotate. Cam 92 intermittently pushes push rod 83 in the hydraulic component 8. When push rod 83 is pressed, it compresses the internal hydraulic oil, thus increasing the hydraulic pressure. As the oil pressure in the oil increases, under further compression, the pressure is applied to the impact assembly 6 through the connecting part 7 and the deflection distribution component 5. The oil pressure in the impact assembly 6 increases and pushes the push plate 62 and the impact column 64 to move. While stretching the spring 63, the impact column 64 impacts and vibrates towards the outer side of the fastener, and the impact direction is maintained in the direction that loosens the fastening nut. With the rotation of the power assembly 9 and the elastic reset of the spring 63, the impact assembly 6 reciprocates to impact the fastening nut. At the same time as the impact and vibration, the control part 4 is activated and reverses its action, causing the impact assembly 6 to deflect in the opposite direction, changing the impact direction on the fastener. Thus, by switching the impact and vibration in different directions, the rusted fastener is loosened, and then the fastener is unscrewed normally with the help of auxiliary equipment.

[0035] First, by rotating the power component 9, the outer surrounding hydraulic component 8 is repeatedly compressed. Using the hydraulic guidance of the connecting part 7 and the deflection distribution component 5, hydraulic pressure is applied to the impact component 6. Through repeated hydraulic changes, the impact component 6 is repeatedly extended and retracted, impacting and vibrating towards the outer surface of the corroded fastener, thus achieving disassembly and detachment. Simultaneously, by cooperating with the control part 4 and the inner and outer gear rings 2 and 3, the forward and reverse rotation of the deflection distribution component 5 is controlled, changing the impact direction of the impact component 6. Through repeated impacts in both directions, the fastener is effectively disassembled and detached, removing it from its corroded state. The fastener then loosens itself along the connecting screw. With the assistance of an unscrewing device, the corroded fasteners on the hydraulic support are quickly and effectively disassembled and detached, greatly improving maintenance, replacement, and usage efficiency.

[0036] Example 2: During the reciprocating impact vibration, the solenoid valve in the lubrication assembly 10 is intermittently opened, making the hydraulic pipe 102 connected to the hydraulic assembly 8. When the power assembly 9 rotates and intermittently squeezes the hydraulic assembly 8, the hydraulic oil in the hydraulic assembly 8 is squeezed and the oil pressure rises. Some of the hydraulic oil is further squeezed into the hydraulic pipe 102 and pushes the push rod 106 in the lubrication assembly 10 to move laterally, so that the extrusion plate 107 is squeezed into the fitting 103 in the fixed frame 101. The lubricating oil in the fitting 103 is sprayed out through the slit at the end of the oil spray pipe 104 and sprayed towards the surface of the rusted fasteners that are being disassembled by impact. Some of the oil penetrates into the installation gaps of the fasteners, lubricating the internal contact surfaces and completing the auxiliary disassembly. When the pressure in the hydraulic assembly 8 is restored, the spring 105 in the lubrication assembly 10 pushes the extrusion plate 107 to reset the push rod 106 to reset. The lubricating oil in the fixed frame 101 is replenished into the fitting 103, waiting for subsequent automatic extrusion and spraying.

[0037] First, by utilizing the hydraulic control effect of the power component 9 on the hydraulic component 8, after opening the solenoid valve in the lubrication component 10, and in conjunction with the repeated compression effect in the hydraulic component 8, a portion of the hydraulic pressure is guided to the hydraulic pipe 102. This hydraulic pressure is then applied to the push rod 106, causing the push rod 106 to drive the extrusion plate 107 to reciprocate in the matching 103. During the extrusion process, the lubricating oil in the lubrication component 10 is extruded and sprayed out. In conjunction with the downward-sloping oil spray pipe 104 and the oil spray slit, the oil is sprayed towards the fasteners to avoid spraying lubricating oil. The lubricating oil penetrates into the installation gaps of the fasteners, further achieving lubrication and assisting in improving the disassembly and loosening effect, thus significantly improving the disassembly effect.

[0038] Example 3: During the impact vibration disassembly process, as the power component 9 rotates, the power component 9 synchronously drives the fan blade 112 in the blowing component 11 to rotate. As the fan blade 112 rotates, axial airflow is generated, and the airflow blows downward along the air outlet 113 towards the impact direction. On the one hand, it causes the entangled rust blocks to detach, and on the other hand, it blows the dust generated by the impact vibration outward.

[0039] First, by rotating the power component 9, while controlling the hydraulic state in the hydraulic component 8, the repeated impact vibration of the impact component 6 further drives the blowing component 11 toward the fastener. The axial flow generated by the rotation blows toward the fastener, preventing the dust from spreading directly to the operator's face during the impact vibration process. The active wind blowing changes the direction of dust flying, and on the other hand, it directly blows onto the front of the fastener to clean the rust fragments generated and attached during the impact vibration, thus helping to improve the impact dismantling effect.

[0040] The outer side of the support cylinder 1 is fixedly provided with a control unit 4, which includes a second motor and a second gear. The second motor drives the second gear to rotate, and the second gear meshes with the outer gear ring 3. A retaining ring is fixedly sleeved on the outer surface of the inner gear ring 2, and the retaining ring rotates and is sleeved in the support cylinder 1.

[0041] By using the control unit 4 to provide the rotation direction of the internal gear ring 2 and the external gear ring 3, the deflection direction of the deflection distribution assembly 5 is controlled, thereby controlling the impact direction.

[0042] The guide tube 54 is fixedly connected to the top of the support plate 52, the curved hole 56 is opened in the rotating shaft 51, the guide tube 54 is connected to the curved hole 56, one end of the curved tube 55 is fixedly connected to the outer side of the rotating shaft 51 and is connected to the curved hole 56, and the other end of the curved tube 55 is connected to the impact assembly 6.

[0043] Hydraulic flow is maintained, hydraulic pressure is transmitted, and the impact assembly 6 is supported by forming a flow channel using the guide tube 54, the curved hole 56, and the curved tube 55.

[0044] The impact assembly 6 includes a fixed sleeve 61, a push plate 62, a spring 63, and an impact column 64. The fixed sleeve 61 is fixedly connected to the curved tube 55. The push plate 62 is movably sleeved in the fixed sleeve 61. One end of the spring 63 is fixedly connected in the fixed sleeve 61, and the other end is fixedly connected to the push plate 62. The impact column 64 is movably sleeved at the end of the fixed sleeve 61 and is fixedly connected to the push plate 62.

[0045] By utilizing the telescopic movement of the impact component 6, it directly impacts the outer surface of the fastener, achieving impact vibration, which loosens the corroded fastener and improves the subsequent disassembly effect.

[0046] The connecting part 7 includes a connecting ring 71, a connecting pipe 72, and a notch 73. The connecting ring 71 is fixedly connected to the top of the support cylinder 1 and communicates with the guide pipe 54. The connecting pipe 72 is fixedly sleeved in the connecting ring 71. The notch 73 is opened on the side of the bottom of the connecting pipe 72 and communicates with the connecting ring 71.

[0047] By utilizing the connecting part 7 to provide hydraulic oil flow, the hydraulic action in the hydraulic component 8 can be easily transmitted to the impact component 6, and the notch 73 maintains the connection between the connecting pipe 72 and the connecting ring 71.

[0048] The hydraulic assembly 8 includes a storage sleeve 81, a piston plate 82, a push rod 83, and a spring 84. The storage sleeve 81 is fixedly connected to and communicates with the top end of the connecting pipe 72. The piston plate 82 is movably sleeved in the storage sleeve 81. The push rod 83 is movably sleeved at the end of the storage sleeve 81 and is fixedly connected to the piston plate 82. The spring 84 is fixedly connected in the storage sleeve 81 and is fixedly connected to the piston plate 82. The interiors of the hydraulic assembly 8 and the connecting part 7 are filled with hydraulic oil.

[0049] By utilizing the stored hydraulic oil in the hydraulic component 8, and in conjunction with the contact action between the push rod 83 and the cam 92, the internal hydraulic pressure is changed and controlled, and the spring 84 is used for elastic reset, thus achieving reciprocating compression.

[0050] The power assembly 9 includes a motor 91, a cam 92, and a bracket 93. The motor 91 is fixedly sleeved in the motor sleeve. The bracket 93 is fixedly connected to the top of the connecting ring 71 and is fixedly connected to the motor sleeve. The cam 92 is fixedly sleeved on the output shaft of the motor 91. The push rod 83 is distributed around the outer side of the cam 92.

[0051] The power unit 9 provides rotational power and works with the cam 92 to achieve reciprocating control.

[0052] The impact assembly 6 has a lubrication assembly 10 fixedly mounted on its top. The lubrication assembly 10 is connected to the hydraulic assembly 8. The lubrication assembly 10 includes a fixed frame 101, a hydraulic pipe 102, an adapter 103, an oil injection pipe 104, a spring 105, a push rod 106, and a pressing plate 107. The fixed frame 101 is fixed to the top of the fixed sleeve 61. One end of the hydraulic pipe 102 is fixedly connected to and communicates with the storage sleeve 81, and the other end of the hydraulic pipe 102 passes through the side of the fixed frame 101. The adapter 103 is fixedly sleeved on the other side of the fixed frame 101. With the same axis as the bottom end of the hydraulic pipe 102, the oil injection pipe 104 is fixedly connected to the outer end face of the adapter 103. One end of the push rod 106 is movably sleeved in the hydraulic pipe 102, and the other end is located in the fixed frame 101 and fixedly connected to the extrusion plate 107. One end of the spring 105 is fixed inside the adapter 103, and the other end is fixedly connected to the extrusion plate 107. A solenoid valve is provided in the hydraulic pipe 102. The outer end of the oil injection pipe 104 is inclined downward. The outer end of the oil injection pipe 104 is provided with an oil injection slit. A sealing plug is threaded onto the top of the fixed frame 101.

[0053] The lubrication component 10 utilizes internally filled lubricating oil. When connected to the hydraulic component 8, the repeated compression of the power component 9 guides part of the compression action into the hydraulic pipe 102, thereby achieving repeated pushing control of the push rod 106 in the lubrication component 10. With the appropriate fitting 103 and the gap sleeve of the extrusion plate 107, the lubricating oil is automatically extruded and automatically filled. When the lubricating oil level in the fixed frame 101 is lower than that of the appropriate fitting 103, the top sealing plug is opened to replenish the lubricating oil. The oil outlet of the slit maintains a relative seal using the tension of the lubricating oil itself, and it is automatically extruded under pressure to achieve lubrication of the fasteners. In particular, the impact vibration allows the lubricating oil to penetrate into the installation gap, enabling quick disassembly after lubrication.

[0054] Among them, the bottom of the power assembly 9 is fixedly provided with a purging assembly 11. The purging assembly 11 includes a blower 111, a fan blade 112 and an air outlet 113. The blower 111 is fixedly connected to the hydraulic assembly 8 through an outer rod. The fan blade 112 is located in the blower 111. The internal shaft of the fan blade 112 is fixedly connected to the output shaft of the motor 91. The air outlet 113 is opened on the end face of the blower 111.

[0055] By utilizing the blowing effect of the blowing component 11, the dust is blown directly along the front of the fastener, changing the direction of dust flight, reducing the impact of incoming dust, and the blowing action causes the attached rust to detach quickly.

[0056] The working principle and usage process of this invention are as follows: In use, the device is fitted over the outside of the treated fastener, allowing the support cylinder 1 to contact the front of the bracket, keeping the impact component 6 located on the outside of the fastener. The control unit 4 is activated, causing it to rotate the meshing external gear ring 3, simultaneously rotating the internal gear ring 2. The rotation of the internal gear ring 2 drives the deflection distribution component 5 to rotate. As gear 53 rotates with the internal gear ring 2, the impact component 6 is deflected via the rotating shaft 51 and the curved tube 55, causing the impact component 6 to tilt towards the outer side of the fastener. The three sets of distributed impact components 6 deflect synchronously. The power component 9 is activated, and the motor 91 drives the cam 92 to rotate. The cam 92 intermittently pushes the push rod 83 in the hydraulic component 8. When push rod 83 is pressed, it compresses the internal hydraulic oil, increasing the oil pressure. Under further compression, the pressure is applied to the impact assembly 6 through the connecting part 7 and the deflection distribution assembly 5. The increased oil pressure in the impact assembly 6 pushes the push plate 62 and the impact column 64 to move. While stretching spring 63, the impact column 64 impacts and vibrates towards the outer side of the fastener, maintaining the impact direction in a way that loosens the fastening nut. With the rotation of the power assembly 9 and the elastic return of spring 63, the impact assembly 6 reciprocates in impacting the fastening nut. Simultaneously with the impact vibration, the control part 4 is activated and reverses its operation, causing the impact assembly 6 to deflect in the opposite direction, changing the impact direction on the fastener, thus achieving the desired effect from different directions. The system switches between impact and vibration to loosen the rusted fasteners, and then uses auxiliary equipment to unscrew them normally. During the reciprocating impact and vibration process, the solenoid valve in the lubrication assembly 10 is intermittently opened, allowing the hydraulic pipe 102 to connect with the hydraulic assembly 8. When the power assembly 9 rotates and intermittently squeezes the hydraulic assembly 8, the hydraulic oil in the hydraulic assembly 8 is squeezed and the oil pressure increases. Some of the hydraulic oil is further squeezed into the hydraulic pipe 102, pushing the push rod 106 in the lubrication assembly 10 to move laterally. This causes the extrusion plate 107 to be squeezed into the matching 103 in the fixed frame 101, and the lubricating oil in the matching 103 is sprayed out through the slit at the end of the oil spray pipe 104, spraying oil towards the surface of the rusted fasteners that have been disassembled by impact. Oil permeates into the installation gaps of the fasteners, lubricating the internal contact surfaces and facilitating disassembly. When the pressure in the hydraulic component 8 is restored, the spring 3 105 in the lubrication component 10 pushes the extrusion plate 107 to reset the push rod 2 106, and the lubricating oil in the fixing frame 101 is replenished into the matching 103, waiting for subsequent automatic extrusion and spraying. During the impact and vibration disassembly process, as the power component 9 rotates, the power component 9 synchronously drives the fan blade 112 in the blowing component 11 to rotate. As the fan blade 112 rotates, axial airflow is generated, and the airflow blows downward along the air outlet 113 towards the impact direction. On the one hand, it causes the entangled rust to detach, and on the other hand, it blows the dust generated by the impact and vibration outward.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
