Description

Technical Field

[0001] This invention relates to the field of tunnel support technology, and more particularly to a support device with angle adjustment function for tunnels with different slopes. Background Technology

[0002] A roadway is a passage used to connect the surface and the ore body. Its functions can be divided into transporting minerals, ventilation, and personnel access. According to its spatial location, roadways can be divided into vertical roadways, horizontal roadways, and inclined roadways. In order to maintain the stability of the roadway and prevent the roadway end face from shrinking too much, the roadway is generally supported.

[0003] When supporting inclined roadways, to prevent the support frame from sliding, it is necessary to adjust the angle between the support frame and the roadway according to the inclination angle of the roadway, so that the support legs form a certain angle with the direction perpendicular to the bottom of the roadway. This angle is called the inclination angle. Currently, the inclined roadway is directly supported by an integral support frame, which has poor support effect and is difficult to adapt to changes in the inclination angle. When a local collapse occurs in the roadway, the top of the support frame is subjected to uneven pressure. When the local pressure is too large, it will cause local deformation of the support frame, affecting the safety of the workers. Summary of the Invention

The sealing frame is provided with symmetrically distributed arc-shaped through holes. The sealing frame and the sliding disc cooperate to divide the cavity of the sliding cylinder into two parts. A second rotating rod is fixedly connected to the sealing frame. The second rotating rod is slidably engaged with the sliding cylinder. A first rotating handle is fixedly connected to the second rotating rod.

[0008] Furthermore, the expansion assembly includes symmetrically distributed sliding rods, which are fixedly connected to the first support frame and slidably connected to the second support frame.

The third rotating rod is fixedly connected to the first gear and the third rotating rod is fixedly connected to the second rotating handle. The second support frame is fixedly connected to the first rack, which meshes with the first gear.

[0009] Furthermore, the positioning assembly includes equidistantly distributed sliding frames, which are slidably connected to a first support frame and a second support frame. Each sliding frame is provided with a support block, and a spring is provided between the support block and the sliding frame. A first sliding block is slidably connected to the support block, and a spring is provided between the first sliding block and the support block.

[0015] The beneficial effects of the technical solution provided by this invention are:

[0016] 1.

The relative positions of the first support frame and the first rotating plate are fixed by the fixing components. The adjustment components are used to adapt to the excessive local pressure on the first support frame when a partial collapse occurs in the roadway, thereby improving the support strength.

[0017] 2. By moving the first rotating rod in the opposite direction, the top and bottom of the roadway are anchored respectively, so that the first rotating plate and the first support frame remain stable.

[0018] 3. By contacting the first sliding block and the support block through the collapsed area at the top of the tunnel, the adjacent support block slides towards the support block under pressure, making the stress more concentrated and improving the support effect at the pressure point.

Detailed Implementation

[0030] The technical solution will be further explained below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," "right," "front," and "back" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to the components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning.

[0031] Example 1

[0032] A support device with angle adjustment function for roadways with different slopes, such as Figure 1 and Figure 2As shown, the device includes a first rotating plate 1 symmetrically distributed on both sides. A rotating frame 2 is rotatably connected to the first rotating plate 1. A drive shaft 3 is slidably connected to the upper side of the rotating frame 2. The rotating frames 2 on the upper and lower sides of the drive shaft 3 are symmetrically distributed. A first fixed frame 4 is fixedly connected to the opposite side of the lower rotating frame 2. A drive motor 5 is mounted on the first fixed frame 4. The drive motor 5 is driven by the drive shaft 3 through a gear set. A hydraulic push rod 6 is mounted on the first fixed frame 4. A second fixed frame 7 is fixedly connected to the opposite side of the upper rotating frame 2. The second fixed frame 7 is fixedly connected to the telescopic end of the hydraulic push rod 6 and is slidably connected to the first fixed frame 4. A first support frame 8 is rotatably connected to the upper rotating frame 2. Adjacent first support frames 8 are slidably connected for easy transportation and disassembly. A fixing component 9 is provided on the rotating frame 2 to fix the device and prevent relative sliding, thus reducing the support effect. Component 9 includes a first rotating rod 901 threadedly connected to the rotating frame 2, a transmission rod 902 slidably connected to the first rotating rod 901, and a transmission rod 902 fixedly connected to the transmission shaft 3. The transmission rod 902 is used to transmit power from the transmission shaft 3 to the first rotating rod 901. A third fixed frame 903 is fixedly connected to the upper side of the first rotating rod 901. Arc-shaped baffles 904, which are always slidably engaged with the first support frame 8 on both sides, are fixedly connected to the upper side of the third fixed frame 903. The rotating frame 2 is provided with an anti-sway component 10, which fixes the angle between the rotating frame 2 and the first rotating plate 1, and between the rotating frame 2 and the first support frame 8 through symmetrically arranged anti-sway components 10. The first support frame 8 is provided with an expansion component 11, which is used to increase the support area of ​​the first support frame 8 on the top of the roadway. The first support frame 8 is provided with an adjustment component 12, which is used to increase the support force of the first support frame 8 at the point where the local pressure is too large after a partial collapse of the roadway.

[0033] like Figure 3 and Figure 4As shown, the anti-sway assembly 10 includes a fourth fixed frame 1001 symmetrically distributed on the front and rear sides of the rotating frame 2. The fourth fixed frame 1001 is fixedly connected to a sliding cylinder 1002 filled with hydraulic oil. The sliding cylinder 1002 is slidably connected to a sliding disc 1003. The sliding disc 1003 has symmetrically distributed arc-shaped through holes. The sliding disc 1003 is fixedly connected to a sliding shaft 1004, which is slidably connected to the sliding cylinder 1002. The upper side of the sliding shaft 1004 is slidably engaged with the first support frame 8. The sliding disc 1003 is located away from the sliding shaft 1002. A sealing frame 1005 is rotatably connected to one side of 004. The sealing frame 1005 is provided with an arc-shaped through hole with the same shape as the arc-shaped through hole at the sliding plate 1003. The sealing frame 1005 cooperates with the sliding plate 1003 to divide the cavity of the sliding cylinder 1002 into upper and lower cavities. A second rotating rod 1006 that slides with the sliding cylinder 1002 is fixedly connected to the sealing frame 1005. A first rotating handle 1007 is fixedly connected to the end of the second rotating rod 1006 away from the sealing frame 1005. The first rotating handle 1007 is located outside the sliding cylinder 1002.

[0034] When using this device to support an inclined roadway, the worker places the device at the position to be supported. At this time, the sealing frame 1005 cooperates with the sliding plate 1003, dividing the sliding cylinder 1002 into upper and lower cavities. The hydraulic oil inside the sliding cylinder 1002 fixes the positions of the sliding plate 1003 and the sealing frame 1005. The worker rotates the lower first rotating handle 1007, which drives the sealing frame 1005 to rotate along the sliding plate 1003 via the second rotating rod 1006. This connects the arc-shaped through hole at the sealing frame 1005 with the arc-shaped through hole at the sliding plate 1003, thus connecting the upper and lower cavities of the lower sliding cylinder 1002. The operator fully contacts the first rotating plate 1 with the bottom of the tunnel and manually adjusts the angle between the rotating frame 2 and the bottom of the tunnel. At this time, the lower sliding shaft 1004 is stretched or compressed by the first rotating plate 1. The hydraulic oil inside the sliding cylinder 1002 flows through the arc-shaped through hole at the sliding plate 1003. After the angle between the rotating frame 2 and the bottom of the tunnel is adjusted, the operator rotates the lower first rotating handle 1007 to close the arc-shaped through hole at the sealing frame 1005 and the arc-shaped through hole at the sliding plate 1003. The hydraulic oil inside the lower sliding cylinder 1002 fixes the position of the sliding plate 1003 and the sealing frame 1005, so that the first rotating plate 1 is in close contact with the bottom of the tunnel.

[0035] After the first rotating plate 1 and the rotating frame 2 are adjusted, the operator rotates the first rotating handle 1007 on the upper side. The sliding plate 1003 and the sealing frame 1005 inside the upper sliding cylinder 1002 rotate relative to each other, connecting the upper and lower cavities of the upper sliding cylinder 1002. The operator then activates the hydraulic push rod 6, and the telescopic end of the hydraulic push rod 6 extends upward. The telescopic end of the hydraulic push rod 6 drives the upper rotating frame 2 to move upward. The upper rotating frame 2 drives the first support frame 8 to move upward. The first support frame 8 drives the second support frame 1102 to move upward through the sliding rod 1101. When the second support frame 1102 is completely in contact with the top of the tunnel, the operator closes the hydraulic push rod 6 and rotates the first rotating handle 1007 on the upper side, separating the upper and lower cavities of the upper sliding cylinder 1002. The hydraulic oil inside the upper sliding cylinder 1002 controls the sliding plate 1003 and the sealing frame 1005 to remain stationary, keeping the first support frame 8 stable.

[0036] After completing the above steps, the staff starts the drive motor 5. The drive motor 5 transmits power to the transmission shaft 3 through the gear set, causing the transmission shaft 3 to rotate. The transmission shaft 3 drives the transmission rod 902 to rotate, and the transmission rod 902 drives the third fixed frame 903 to rotate. The third fixed frame 903 cooperates with the rotating frame 2 and extends spirally into the top and bottom of the tunnel. The first rotating rod 901 fixes the angle of the rotating frame 2, so that the rotating frame 2 and the tunnel form a stable angle, i.e., the angle of attack. The drive motor 5 is then turned off, and the support is completed. When the upper rotating frame 2 rotates, the rotating frame 2 drives the arc-shaped shield 904 to rotate through the third fixed frame 903. The arc-shaped shield 904 always slides in contact with the first support frame 8 to prevent gravel from entering between the first support frame 8 and the rotating frame 2 during the rotating drilling process.

[0037] When using this device to support horizontal roadways, workers do not need to adjust the anti-sway component 10, that is, they do not need to rotate the rotating frame 2. The other steps are the same as those for supporting inclined roadways.

[0038] When dismantling the device installed in the inclined tunnel, the worker starts the drive motor 5 to rotate in the reverse direction. The drive motor 5 drives the transmission shaft 3 to rotate in the reverse direction via the gear set. The transmission shaft 3 drives the transmission rod 902 to rotate in the reverse direction. The transmission rod 902 drives the first rotating rod 901 to move along the spiral protrusion at the rotating frame 2 towards the transmission shaft 3, causing the first rotating rod 901 to lose its engagement with the top and bottom of the tunnel. The drive motor 5 is then turned off, and the worker starts the hydraulic push rod 6. The telescopic end of the hydraulic push rod 6 retracts downward, and the telescopic end of the hydraulic push rod 6 drives the second fixed frame 7 to move downward. The second fixed frame 7 drives the upper rotating frame 2 to move downwards. The upper rotating frame 2 drives the first support frame 8 and the second support frame 1102 to move downwards synchronously. When the telescopic end of the hydraulic push rod 6 is fully retracted, the operator manually rotates the first rotating handle 1007 to connect the upper and lower cavities of the sliding cylinder 1002. The operator rotates the first rotating plate 1 and the first support frame 8 to their original positions to reset the sliding plate 1003. After the sliding plate 1003 is reset, the operator rotates the first rotating handle 1007 to separate the upper and lower cavities of the sliding cylinder 1002, thus completing the dismantling.

[0039] When removing a device installed in a horizontal roadway, the operator does not need to control the anti-sway component 10; the other steps are the same as those for removing a device installed in an inclined roadway.

[0040] Example 2

[0041] Based on Example 1, such as Figure 5 and Figure 6 As shown, the expansion assembly 11 includes a sliding rod 1101 fixedly connected to the front and rear sides of the first support frame 8. The sliding rod 1101 is slidably connected to the second support frame 1102. A fifth fixed frame 1103 is fixedly connected to the lower side of the first support frame 8. A third rotating rod 1104 is rotatably connected to the fifth fixed frame 1103. A first gear 1105 is fixedly connected to the upper end of the third rotating rod 1104. A second rotating handle 1106 is fixedly connected to the lower end of the third rotating rod 1104. A first rack 1107 that meshes with the first gear 1105 is fixedly connected to the second support frame 1102. The second rotating handle 1106 controls the second support frame 1102 to expand outward or contract inward.

[0042] After temporary support is provided for the device, workers manually rotate the second rotating handle 1106. The second rotating handle 1106 drives the first gear 1105 to rotate via the third rotating rod 1104. The first gear 1105 drives the two centrally symmetrical first racks 1107 to move forward and backward respectively. The first racks 1107 drive the second support frame 1102, which is fixed to them, to slide along the sliding rod 1101 to the side away from the first support frame 8. The second support frame 1102 drives the sliding frame 1201 to slide synchronously, expanding the support area of ​​the device on the top of the roadway. When the device is dismantled, workers rotate the second rotating handle 1106 in the opposite direction. The first gear 1105 causes the first racks 1107 to drive the second support frame 1102 to move along the sliding rod 1101 to the opposite side for resetting.

[0043] Example 3

[0044] Based on Example 2, such as Figure 7 and Figure 8 As shown, the adjustment assembly 12 includes equidistantly distributed sliding frames 1201. The sliding frames 1201 are slidably connected to the first support frame 8 and the second support frame 1102. A support block 1202 is slidably connected to the upper side of the sliding frame 1201. Springs fixed to the sliding frame 1201 are provided on the left and right sides of the support block 1202. A cavity is provided on the upper side of the support block 1202. A first sliding block 1203 is slidably connected to the cavity of the support block 1202. The first sliding block 1203 and the support block 1202 are connected to each other. A spring is provided between the bottom of the cavity 02. The lower side of the first sliding block 1203 is fixed with L-shaped blocks 1204 that are symmetrically distributed on the left and right. The first sliding block 1203 is slidably connected to an arc-shaped connecting plate 1205. The arc-shaped connecting plate 1205 is provided with a through groove that slides with the L-shaped block 1204. The arc-shaped connecting plate 1205 is provided with a protrusion that contacts and cooperates with the support block 1202. The outer edge of the first sliding block 1203 is located below the outer edge of the first support frame 8 to prevent the adjustment component 12 from misjudging.

[0045] When the roadway supported by this device undergoes local deformation, the deformed area of ​​the roadway compresses the first sliding block 1203, causing the first sliding block 1203 to slide along the support block 1202. The first sliding block 1203 drives the L-shaped block 1204 to move, and the L-shaped block 1204 contacts the through groove at the arc-shaped connecting plate 1205, causing the arc-shaped connecting plate 1205 to slide relative to it. The arc-shaped connecting plate 1205, through symmetrical protrusions, drives another support block 1202 that slides with it to slide relative to this support block 1202, thereby improving the support effect of the first support frame 8 on the roadway deformation area and preventing the device from deforming due to different forces on the upper side of the device, which could affect the safety of the workers. By setting the outer edge of the first sliding block 1203 on the lower side of the outer edge of the first support frame 8, the unevenness of the roadway top can prevent the adjustment component 12 from being triggered.

[0046] Example 4

[0047] Based on Example 3, such as Figure 9 and Figure 10 As shown, it also includes a support assembly 13, which is disposed on the second fixed frame 7. The support assembly 13 includes a rotating shaft 1301 symmetrically distributed front and rear. The rotating shaft 1301 is slidably connected to the second fixed frame 7. The rotating shaft 1301 is fixedly connected to a first support leg 1302. In the initial state, the first support leg 1302 forms a certain angle with the second fixed frame 7. A second support leg 1303 is slidably connected to the lower side of the first support leg 1302. Both the first support leg 1302 and the second support leg 1303 are provided with equidistantly distributed through holes. A pin is provided at one set of overlapping through holes of the first support leg 1302 and the second support leg 1303. Through the cooperation of the first support leg 1302 and the second support leg 1303, the device is assisted. The second support leg 1303 is rotatably connected to a second rotating plate 1304 that contacts the bottom of the tunnel. A rotating shaft 1301 is splinedly connected to a rotating crank 1305. The rotating crank 1305 is rotatably connected to a second sliding block 1306 that slides with the second fixed frame 7. The second sliding block 1306 is provided with a limiting shaft. The rotating shaft 1301 is fixedly connected to a limiting disk 1307. The limiting disk 1307 is provided with circumferentially equidistant through holes. The through holes of the limiting disk 1307 are limited and engaged with the limiting shaft of the second sliding block 1306. The rotating shaft 1301 is fixedly connected to a second gear 1308. The second fixed frame 7 is fixedly connected to a second rack 1309 that is symmetrically distributed front and rear. The second rack 1309 meshes with its adjacent second gear 1308.

[0048] During the process of using this device to support the inclined roadway, when the worker releases the anti-sway component 10 from the angle restriction of the first rotating plate 1, the worker releases the pins installed at the through holes of the first support leg 1302 and the second support leg 1303. After the angle between the first rotating plate 1 and the first support frame 8 and the rotating frame 2 is fixed, the worker fixes the through hole between the first support leg 1302 and the adjacent second support leg 1303 near the bottom of the roadway using the pins. The worker pulls the rotating crank 1305 away from the bottom of the roadway. The rotating crank 1305 drives the second sliding block 1306 to slide synchronously, causing the limiting shaft at the second sliding block 1306 to lose its limitation on the limiting plate 1307. The worker then rotates the rotating crank 1305 away from the bottom of the roadway, causing the crank 1305 to drive the... The rotating shaft 1301 rotates, driving the second gear 1308 to rotate. The second gear 1308 moves upward along the second rack 1309, driving the rotating shaft 1301 to move upward. The rotating shaft 1301 drives the limiting plate 1307 and the rotating crank 1305 to move upward. The rotating crank 1305 drives the second sliding block 1306 to slide upward along the second fixed frame 7. The rotating shaft 1301 drives the first support leg 1302 to rotate and move upward, adjusting the support point of the first support leg 1302 on the second fixed frame 7 to improve the support effect. The first support leg 1302 drives the second support leg 1303 to move relative to each other, and the second support leg 1303 slides downward along the first support leg 1302, so that the second rotating plate 1304 is always in contact with the bottom of the roadway.

[0049] When the second support leg 1303 is adjusted to the appropriate angle, the operator pushes the crank 1305 to rotate. The crank 1305 drives the second sliding block 1306 to slide, so that the limiting shaft at the second sliding block 1306 limits the limiting plate 1307 to prevent the first support leg 1302 from shaking. After the limiting is completed, the through hole between the first support leg 1302 and the second support leg 1303 is fixed by a pin.

[0050] When dismantling the device installed in the inclined tunnel, the worker releases the pin at the through hole between the first support leg 1302 and the second support leg 1303. The worker then pulls the rotating crank 1305 on the side away from the bottom of the tunnel. Rotating the crank 1305 causes the second sliding block 1306 to release its restriction on the limiting plate 1307. Rotating the crank 1305 in the opposite direction causes the second gear 1308 to move downward along the second rack 1309. After the second gear 1308 moves to its original position, the worker pushes the rotating crank 1305 to restrict the limiting plate 1307 at the limiting shaft at the second sliding block 1306.
