Technical Field

[0001] This utility model belongs to the field of mining hydraulic support technology, specifically a composite energy-consuming single hydraulic support device for mining. Background Technology

[0002] Single hydraulic props represent a significant achievement in coal mine support technology. With their excellent constant resistance, high supporting force, and ease of operation, they play an irreplaceable role in coal mine safety production. Correct selection, standardized use, and meticulous maintenance are crucial to ensuring optimal support effectiveness and safeguarding the working face.

[0003] Currently, the lifting and supporting components of existing single hydraulic props are generally rigidly connected. This makes the lifting and supporting components of the single hydraulic props prone to deformation or breakage due to excessive pressure caused by mountain swaying during use. This not only limits the supporting effect of the single hydraulic props but also poses serious safety hazards. Therefore, it is necessary to design a composite energy-consuming single hydraulic support device for mines. Utility Model Content

[0004] To address the aforementioned issues, and to resolve the problem that existing single hydraulic props typically employ rigid connections between their lifting and supporting components, which can lead to deformation or breakage due to excessive pressure caused by mountain swaying during use, thus limiting the support effectiveness of the single hydraulic prop and posing serious safety hazards, this invention provides a composite energy-dissipating single hydraulic support device for mining. This device effectively achieves rapid assembly, with convenient movement and disassembly of components during assembly. It also provides stable and reliable energy dissipation between the lifting and supporting components of the single hydraulic prop. Furthermore, after energy dissipation, the hydraulic lifting and supporting components can reset within the energy dissipation range of the dissipating components and continue to provide energy-dissipating support. This not only improves the support effect but also ensures the reliability of the device. The device has a simple structure and strong practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite energy-consuming single hydraulic support device for mining, comprising a hydraulic lifting assembly, wherein the fixed end of the hydraulic lifting assembly is connected to the support surface of the mine roadway, and the lifting end of the hydraulic lifting assembly is detachably connected to an energy-consuming assembly, wherein the energy-consuming end of the energy-consuming assembly is provided with a top support assembly. The hydraulic lifting assembly is used to drive the energy-consuming assembly and the top support assembly to move linearly up and down in the vertical direction. The energy-consuming assembly is used to dissipate energy by releasing pressure between the top support assembly and the hydraulic lifting assembly. The top support assembly is used to perform support operations inside the mine roadway.

[0006] The aforementioned composite energy-consuming single hydraulic support device for mining includes a hydraulic lifting component comprising a hydraulic cylinder, a bottom support plate provided on the outer wall of the bottom surface of the hydraulic cylinder, and a vertical hole provided on the outer wall of the bottom support plate, wherein the vertical hole is used to connect with an external connector and the support surface of the mine roadway. One end of the hydraulic lifting column is slidably connected to the inner wall of the hydraulic cylinder, and the other end of the hydraulic lifting column is provided with a support plate. The upper surface of the support plate is provided with a connecting hole, and the outer wall of the support plate is provided with a limit hole.

[0007] The aforementioned composite energy-consuming single hydraulic support device for mining includes a composite elastic steel plate, which is attached to the upper surface of a support plate, and a connecting shaft is inserted into the outer wall of the composite elastic steel plate. The two ends of the connecting shaft are connected to connecting plates, and the outer wall of the connecting plate is provided with a sliding groove. A pressure plate is attached to the upper surface of the laminated elastic steel plate, and the pressure plate and the support plate are detachably connected by fasteners, wherein the fasteners can penetrate the vertical holes.

[0008] The aforementioned composite energy-consuming single hydraulic support device for mining includes a top support assembly comprising a support beam, wherein the outer side wall of the support beam has a side hole, and the inner side wall of the side hole is slidably connected to the inner side wall of the chute. The outer wall of the bottom surface of the support beam is provided with a limiting rod, and the outer wall of the limiting rod is slidably connected to the inner wall of the limiting hole.

[0009] In the aforementioned composite energy-dissipating single hydraulic support device for mining, one end of an energy-dissipating spring is provided on the upper surface of the pressure plate, and the other end of the energy-dissipating spring is connected to the outer wall of the bottom surface of the support beam.

[0010] In the aforementioned composite energy-dissipating single hydraulic support device for mining, there are two side holes and two connecting plates, and the two connecting plates are symmetrically distributed on both sides of the energy-dissipating spring.

[0011] In the aforementioned composite energy-consuming single hydraulic support device for mining, there are multiple limiting rods, and the multiple limiting rods are symmetrically distributed on both sides of the composite elastic steel plate.

[0012] In the aforementioned composite energy-consuming single hydraulic support device for mining, there are multiple hydraulic lifting components and energy-consuming components, and these multiple hydraulic lifting components and energy-consuming components are evenly distributed on the outer wall of the bottom surface of the support beam.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) First, move the hydraulic lifting assembly to the required position, then connect the bottom support plate to the mine roadway support surface by using the external connector along the vertical hole. This allows for a detachable connection between the hydraulic lifting assembly and the mine roadway support surface. Next, move the composite elastic steel plate to the upper surface of the support plate, then move the pressure plate to adhere to the upper surface of the composite elastic steel plate and rotate the fastener along the connection hole to detachably connect the pressure plate and the support plate. This limits the composite elastic steel plate to the middle position between the pressure plate and the support plate. Then, move the support beam and connect the limiting rod to the limiting rod. The holes are aligned, and then the limiting rod is inserted along the limiting hole to fit and connect the outer wall of the bottom surface of the support beam with the upper end of the energy dissipation spring. Then, the connecting plate is inserted along the side hole, and the connecting shaft is inserted along the outer wall of the stacked elastic steel plate and connected to the connecting plate to limit the position between the stacked elastic steel plate and the support beam. This effectively realizes the function of rapid assembly of the device, and the movement and disassembly of each component are relatively convenient during the assembly process. This not only improves the assembly efficiency of the device, but also facilitates the inspection, maintenance and secondary use of the device. The device has a simple structure and strong applicability.

[0014] (2) The hydraulic cylinder drives the hydraulic lifting column to move linearly, thereby driving the support plate to move linearly. This allows the upper surface of the support beam to fit against the support surface inside the mine roadway. When the load on the upper surface of the support beam increases, the elastic deformation force of the superimposed elastic steel plate can drive the connecting plate to move laterally, causing the slide groove and the inner wall of the side hole to slide against each other. Then, under the action of the limit rod sliding linearly along the limit hole, the load on the upper surface of the support beam can be stably dissipated. At the same time, the elastic deformation force of the energy dissipation spring between the support beam and the pressure plate can assist the elastic deformation force of the superimposed elastic steel plate in dissipating the load on the upper surface of the support beam. This effectively realizes that the device has the function of dissipating energy between the lifting component and the support component of the single hydraulic prop. The entire energy dissipation process is relatively stable and reliable. After the energy dissipation, the hydraulic lifting component and the top support component can reset within the energy dissipation range of the energy dissipation component and continue to produce an energy dissipation support effect. This not only improves the support effect of the device but also ensures the support reliability of the device. The device has a simple structure and strong practicality. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example Depend on Figures 1-4 This invention discloses a composite energy-dissipating single hydraulic support device for mines, comprising a hydraulic lifting assembly 1. The fixed end of the hydraulic lifting assembly 1 is connected to the support surface of the mine roadway, and the lifting end of the hydraulic lifting assembly 1 is detachably connected to an energy-dissipating assembly 2. The energy-dissipating end of the energy-dissipating assembly 2 is provided with a top support assembly 3. The hydraulic lifting assembly 1 is used to drive the energy-dissipating assembly 2 and the top support assembly 3 to move linearly vertically. The energy-dissipating assembly 2 is used to dissipate energy by releasing pressure between the top support assembly 3 and the hydraulic lifting assembly 1. The top support assembly 3 is used to provide support for the interior of the mine roadway. This invention achieves a quick assembly function, and the movement and disassembly of each component during the assembly process are relatively convenient. It also achieves a stable and reliable energy dissipation function between the lifting and supporting components of the single hydraulic support. Furthermore, after energy dissipation, the hydraulic lifting assembly 1 and the top support assembly 3 can reset within the energy dissipation range of the energy-dissipating assembly 2 and continue to produce an energy-dissipating support effect, which not only improves the support effect of the device but also ensures the support reliability of the device.

[0018] Specifically, the hydraulic lifting assembly 1 includes a hydraulic cylinder 101. A bottom support plate 102 is provided on the outer wall of the bottom surface of the hydraulic cylinder 101, and a vertical hole 103 is provided on the outer wall of the bottom support plate 102. The vertical hole 103 is used to connect with the external connector and the support surface of the mine roadway. One end of a hydraulic lifting column 104 is slidably connected to the inner wall of the hydraulic cylinder 101, and a support plate 105 is provided on the other end of the hydraulic lifting column 104. A connection hole 106 is provided on the upper surface of the support plate 105, and a limit hole 107 is provided on the outer wall of the support plate 105. The hydraulic cylinder 101 drives the hydraulic lifting column 104 to move linearly, thereby driving the support plate 105 to move linearly, which in turn drives the upper surface of the support beam 301 to fit against the support surface inside the mine roadway.

[0019] Specifically, the energy-dissipating component 2 includes a laminated elastic steel plate 201, which is attached to the upper surface of the support plate 105. A connecting shaft 202 is inserted into the outer wall of the laminated elastic steel plate 201, and connecting plates 203 are connected to both ends of the connecting shaft 202. A sliding groove 204 is provided on the outer wall of the connecting plate 203. A pressure plate 205 is attached to the upper surface of the laminated elastic steel plate 201. The pressure plate 205 and the support plate 105 are detachably connected by fasteners 206, which can penetrate the vertical hole 103. The elastic deformation force of the laminated elastic steel plate 201 can drive the connecting plate 203 to move laterally, thereby causing the sliding groove 204 to slide against the inner wall of the side hole 302. Under the action of the limiting rod 303 sliding linearly along the limiting hole 107, the load on the upper surface of the support beam 301 can be stably dissipated.

[0020] Specifically, the top support assembly 3 includes a support beam 301, the outer wall of the support beam 301 has a side hole 302, and the inner wall of the side hole 302 is slidably connected to the inner wall of the slide groove 204; the outer wall of the bottom surface of the support beam 301 is provided with a limiting rod 303, and the outer wall of the limiting rod 303 is slidably connected to the inner wall of the limiting hole 107. By moving the support beam 301 and aligning the limiting rod 303 with the limiting hole 107, and then inserting the limiting rod 303 along the limiting hole 107, the outer wall of the bottom surface of the support beam 301 can be attached and connected to the upper end of the energy dissipation spring 207.

[0021] Specifically, one end of an energy-dissipating spring 207 is provided on the upper surface of the pressure plate 205, and the other end of the energy-dissipating spring 207 is connected to the outer wall of the bottom surface of the support beam 301. The elastic deformation force of the energy-dissipating spring 207 between the support beam 301 and the pressure plate 205 can assist the elastic deformation force of the stacked elastic steel plate 201 in dissipating the load on the upper surface of the support beam 301.

[0022] Specifically, there are two side holes 302 and two connecting plates 203, and the two connecting plates 203 are symmetrically distributed on both sides of the energy dissipation spring 207. By inserting the connecting plate 203 along the side hole 302, and then inserting the connecting shaft 202 along the outer wall of the stacked elastic steel plate 201 and connecting the connecting shaft 202 and the connecting plate 203, the position between the stacked elastic steel plate 201 and the support beam 301 can be limited.

[0023] Specifically, there are multiple limiting rods 303, and the multiple limiting rods 303 are symmetrically distributed on both sides of the laminated elastic steel plate 201. The multiple number of limiting rods 303 makes the limiting function of the limiting rods 303 more reliable.

[0024] Specifically, there are multiple hydraulic lifting components 1 and energy-consuming components 2, and these multiple hydraulic lifting components 1 and energy-consuming components 2 are evenly distributed on the outer wall of the bottom surface of the support beam 301. The fact that there are multiple hydraulic lifting components 1 and energy-consuming components 2 makes the support effect of the support beam 301 more stable.

[0025] In use, first, move the hydraulic lifting assembly 1 to the desired position. Then, along the vertical hole 103, use the external connector to detachably connect the bottom support plate 102 to the mine roadway support surface, thereby positioning the hydraulic lifting assembly 1 and the mine roadway support surface. Next, move the composite elastic steel plate 201 and place it on the upper surface of the support plate 105. Then, move the pressure plate 205 to adhere to the upper surface of the composite elastic steel plate 201 and rotate the fastener 206 along the connection hole 106 to detachably connect the pressure plate 205 and the support plate 105, thereby limiting the composite elastic steel plate 201 between the pressure plate 205 and the support plate 105. 05. In the middle position, the support beam 301 is moved and the limiting rod 303 is aligned with the limiting hole 107. Then, the limiting rod 303 is inserted along the limiting hole 107, so that the outer wall of the bottom surface of the support beam 301 is attached and connected to the upper end of the energy dissipation spring 207. Then, the connecting plate 203 is inserted along the side hole 302, and the connecting shaft 202 is inserted along the outer wall of the stacked elastic steel plate 201, and the connecting shaft 202 is connected to the connecting plate 203, so that the position between the stacked elastic steel plate 201 and the support beam 301 is limited. This effectively realizes the function of rapid assembly of the device, and the movement and disassembly of each component during the assembly process are relatively simple. For convenience, this not only improves the assembly efficiency of the device but also facilitates its inspection, maintenance, and secondary use. Next, the hydraulic cylinder 101 drives the hydraulic lifting column 104 to move linearly, thereby causing the support plate 105 to move linearly. This allows the upper surface of the support beam 301 to fit against the support surface inside the mine roadway. When the load on the upper surface of the support beam 301 increases, the elastic deformation force of the overlapping elastic steel plate 201 causes the connecting plate 203 to move laterally, allowing the slide groove 204 to slide against the inner wall of the side hole 302. Furthermore, under the linear sliding action of the limiting rod 303 along the limiting hole 107, the support... The load on the upper surface of beam 301 is stably dissipated. At the same time, the elastic deformation force of the energy-dissipating spring 207 between the support beam 301 and the pressure plate 205 assists the elastic deformation force of the superimposed elastic steel plate 201 in dissipating the load on the upper surface of the support beam 301. This effectively realizes the function of the device in dissipating energy between the lifting component and the supporting component of the single hydraulic prop. The entire energy dissipation process is relatively stable and reliable. In addition, after energy dissipation, the hydraulic lifting component 1 and the top support component 3 can reset within the energy dissipation range of the energy dissipation component 2 and continue to generate an energy-dissipating support effect. This not only improves the support effect of the device, but also ensures the support reliability of the device.
