Abstract
Description
Technical Field
[0001] This utility model relates to the field of supports, and in particular to a mining safety protection support. Background Technology
[0002] Safety protection brackets are support devices used to prevent injury to equipment, structures, or personnel. They are commonly used in industries such as manufacturing, construction, and machinery.
[0003] During mining, a support frame is placed inside the mine shaft, and hydraulic rods extend the frame, bringing it into contact with the mine wall to provide support and protection. However, debris can easily get into the gaps at the output end of the hydraulic rods, affecting their subsequent extension and retraction, and consequently impacting the effectiveness of the safety support system. Utility Model Content
[0004] The technical problem this invention aims to solve is that when a hydraulic rod is in use, foreign objects can easily enter the gap at the output end of the hydraulic rod, which can affect the subsequent extension and retraction of the hydraulic rod, thus affecting the effectiveness of the safety protection bracket.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a mining safety protection support, including a support, a hydraulic rod provided on one side of the support, and a sealing device provided on one side of the support, wherein the sealing device seals the hydraulic rod by means of a rubber block.
[0006] The effect achieved by the above components is as follows: during mining, the support is placed inside the mine shaft, and then the hydraulic rods expand the support. At this time, a sealing device is used to seal the output end of the hydraulic rods, and then the support is brought into contact with the inner wall of the mine shaft to support and protect the mine shaft.
[0007] Preferably, the sealing device includes a square tube, a first bolt, a connecting plate, and a rubber block. The square tube is disposed on the side of the hydraulic rod near the output end. The first bolt is inserted into the square tube to fix the connecting plate. The rubber block is located on one side of the connecting plate and on the side of the hydraulic rod near the connection point of the output end.
[0008] The effect achieved by the above components is as follows: When the hydraulic rod is in use, the two rubber blocks can be brought into contact with the output end of the hydraulic rod, and then the two rubber blocks can be made into a whole. Then, the rubber blocks can be moved so that the connecting plate fixed on one side of the rubber blocks can be inserted into the square tube fixed on one side of the hydraulic rod. Then, the first bolt can be rotated so that the first bolt passes through the square tube and is threadedly fixed to the connecting plate. By using a sealing device, the rubber blocks can be used to seal the output end of the hydraulic rod, preventing foreign objects from easily entering the gap at the output end of the hydraulic rod, which could affect the subsequent extension and retraction of the hydraulic rod, thereby improving the effectiveness of the safety protection bracket.
[0009] Preferably, the rubber block has a guide block at its upper end, and the middle area of the guide block is higher than the edge area.
[0010] The effect achieved by the above-mentioned components is to guide and remove debris and other contaminants that reach the rubber block by fixing the guide block to the upper end, thereby improving the performance of the sealing device.
[0011] Preferably, a washer is provided on one side of the first bolt, and the washer increases the contact area between the first bolt and the square tube.
[0012] The effect achieved by the above components is as follows: by using a gasket to abut against and fix the first bolt and square tube, the contact area of the first bolt and square tube is increased, thereby improving the fixing effect of the bolt on the connecting plate.
[0013] Preferably, the connecting plate has a trapezoidal block on the side away from the rubber block to reduce the size of one side of the connecting plate.
[0014] The effect achieved by the above components is that by fixing the trapezoidal block to the side of the connecting plate away from the rubber block, the size of one side of the connecting plate is reduced, making it easier for the connecting plate to be inserted into the square tube.
[0015] Preferably, a shielding assembly is provided on one side of the guide block. The shielding assembly includes a second bolt and a shielding plate. The second bolt passes through the shielding plate and is fixed to the guide block. The shielding plate is located at the gap between the two rubber blocks and the two guide blocks.
[0016] The effect achieved by the above components is as follows: after the two rubber blocks and the guide block are connected, the baffle plate is placed in the gap between them, and then the second bolt is rotated so that the second bolt passes through the baffle plate and is threadedly fixed to the guide block. Then the position of the baffle plate is fixed. By using the baffle assembly, the gap between the two rubber blocks and the two guide blocks can be blocked, thereby improving the performance of the rubber blocks and thus improving the performance of the sealing device.
[0017] Preferably, a plurality of anti-slip blocks are provided on one side of the second bolt, and the plurality of anti-slip blocks increase the friction on one side of the second bolt.
[0018] The effect achieved by the above components is that several anti-slip blocks are fixed to the second bolt, making it easier for the second bolt to rotate.
[0019] Preferably, a control frame is provided on one side of the shield, and the control frame increases the size of one side of the shield.
[0020] The effect achieved by the above components is that by fixing the control frame to the baffle, and then raising the size of one side of the baffle, the baffle can be moved more easily.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using a sealing device, rubber blocks are used to seal the output of the hydraulic rod, preventing foreign objects from easily entering the gap at the output end of the hydraulic rod and affecting its subsequent extension and retraction, thereby improving the effectiveness of the safety protection bracket.
[0023] By using a shielding component, the gap between the two rubber blocks and the two guide blocks can be shielded, thereby improving the performance of the rubber blocks and thus improving the performance of the sealing device. Attached Figure Description

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Figures 1 to 4The diagram illustrates a mining safety support system, comprising a support 1, a hydraulic rod 2 on one side of the support 1, and a sealing device 3 on the other side of the support 1. The sealing device 3 seals the hydraulic rod 2 using a rubber block 34. During mining, the support 1 is placed inside the mine shaft, and then the hydraulic rod 2 expands the support 1. At this time, the sealing device 3 seals the output end of the hydraulic rod 2, allowing the support 1 to contact the inner wall of the mine shaft for support and protection.
[0033] Figures 1 to 4 The sealing device 3 shown includes a square tube 31, a first bolt 32, a connecting plate 33, and a rubber block 34. The square tube 31 is located on the side of the hydraulic rod 2 near the output end. The first bolt 32 is inserted into the square tube 31 to fix the connecting plate 33. The rubber block 34 is located on one side of the connecting plate 33 and on the side of the hydraulic rod 2 near the output end connection. When the hydraulic rod 2 is in use, the two rubber blocks 34 can be brought into contact with the output end of the hydraulic rod 2, forming a whole. Then, the rubber blocks 34 are moved so that the connecting plate 33, which is fixed on one side of the rubber blocks 34, is inserted into the square tube 31, which is fixed on one side of the hydraulic rod 2. Then, the first bolt 32 is rotated so that it passes through the square tube 31 and is threadedly fixed to the connecting plate 33. By using the sealing device 3, the rubber block 34 seals the output end of the hydraulic rod 2, preventing debris from easily entering the gap at the output end of the hydraulic rod 2, which could affect the subsequent extension and retraction of the hydraulic rod 2, thereby improving the effectiveness of the safety protection bracket 1.
[0034] Figures 1 to 4 The rubber block 34 shown has a guide block 35 at its upper end, with the middle area of the guide block 35 higher than the edge area. The guide block 35 is fixed to the upper end of the rubber block 34 to guide and remove debris reaching the rubber block 34, thereby improving the effectiveness of the sealing device 3. A washer 36 is provided on one side of the first bolt 32, increasing the contact area between the first bolt 32 and the square tube 31. The washer 36 abuts against and fixes the first bolt 32 and the square tube 31, increasing the contact area and improving the bolt's fixing effect on the connecting plate 33. A trapezoidal block 37 is provided on the side of the connecting plate 33 away from the rubber block 34 to reduce the size of that side. The trapezoidal block 37 is fixed to the side of the connecting plate 33 away from the rubber block 34, reducing the size of that side and making it easier for the connecting plate 33 to be inserted into the square tube 31.
[0035] Figures 1 to 4A shielding assembly 4 is provided on one side of the guide block 35. The shielding assembly 4 includes a second bolt 41 and a shielding plate 42. The second bolt 41 passes through the shielding plate 42 and is fixed to the guide block 35. The shielding plate 42 is located in the gap between the two rubber blocks 34 and the two guide blocks 35. After the two rubber blocks 34 and the guide blocks 35 are mated, the shielding plate 42 is placed in the gap between them. Then, the second bolt 41 is rotated so that the second bolt 41 passes through the shielding plate 42 and is threadedly fixed to the guide block 35. The position of the shielding plate 42 is then fixed. By using the shielding assembly 4, the gap between the two rubber blocks 34 and the two guide blocks 35 can be shielded, thereby improving the performance of the rubber blocks 34 and thus improving the performance of the sealing device 3.
[0036] Figures 1 to 4 The second bolt 41 shown has several anti-slip blocks 43 on one side, which increase the friction on one side of the second bolt 41. The anti-slip blocks 43 are fixed to the second bolt 41, making it easier for the second bolt 41 to rotate. The baffle plate 42 has a control frame 44 on one side, which raises the size of one side of the baffle plate 42. By fixing the control frame 44 to the baffle plate 42 and raising the size of one side of the baffle plate 42, the baffle plate 42 can be moved more easily.
[0037] Working Principle: During mining, the support 1 is placed inside the mine shaft, and then the hydraulic rod 2 expands the support 1. At this time, the sealing device 3 is used to seal the output end of the hydraulic rod 2, and then the support 1 contacts the inner wall of the mine shaft to support and protect the mine shaft. When using the hydraulic rod 2, two rubber blocks 34 can be placed in contact with the output end of the hydraulic rod 2, and the two rubber blocks 34 can be made into a whole. Then, the rubber blocks 34 are moved so that the connecting plate 33 fixed on one side of the rubber blocks 34 is inserted into the square tube 31 fixed on one side of the hydraulic rod 2. Then, the first bolt 32 is rotated so that the first bolt 32 passes through the square tube 31 and is threadedly fixed to the connecting plate 33. By using the sealing device 3, the rubber blocks 34 are used to seal the output of the hydraulic rod 2, preventing foreign objects from easily entering the gap at the output end of the hydraulic rod 2, which could affect the subsequent extension and retraction of the hydraulic rod 2, thereby improving the effectiveness of the safety protection support 1.
[0038] After the two rubber blocks 34 and the guide block 35 are connected, the baffle plate 42 is placed in the gap between them. Then, the second bolt 41 is rotated so that the second bolt 41 passes through the baffle plate 42 and is threadedly fixed to the guide block 35. Then the position of the baffle plate 42 is fixed. By using the baffle assembly 4, the gap between the two rubber blocks 34 and the two guide blocks 35 can be blocked, thereby improving the performance of the rubber blocks 34 and thus improving the performance of the sealing device 3.
