Description

Technical Field

[0001] This invention relates to coal mining technology, specifically to a temporary reinforcement and support device for coal mine roadways during coal mining and tunneling. Background Technology

[0002] The working environment of coal mine roadway excavation is complex and changeable, and the roof pressure exhibits obvious dynamic and regional characteristics. As a key piece of equipment to ensure the safety of the tunneling face, the structural stability and adaptability of temporary support devices are directly related to the safety of workers and the efficiency of tunneling. Especially in working conditions where the cross-sectional dimensions of the roadway change frequently or the roof conditions vary greatly, if the temporary support device cannot quickly adjust the support height and achieve reliable locking according to the actual needs of the site, gaps or uneven stress will appear between the support body and the roof, which can easily lead to local roof collapse accidents and seriously affect the continuity and reliability of mine safe production.

[0003] Existing temporary reinforcement support devices for coal mine roadways typically use rigid connections such as bolt fastening or pin insertion for support height adjustment and limit locking. The lack of a linkage and conversion mechanism between the adjustment components means that after the height is positioned, manual re-alignment of the holes and application of significant external force are required to complete the fixing, which is cumbersome and time-consuming. When it is necessary to frequently switch the support state in roadway cross-sections at different heights, this non-linkage step-by-step adjustment structure cannot achieve height adaptation and automatic locking simultaneously through a single operation. This not only increases the labor intensity of the workers but also prolongs the support response time during the emergency window period when the roof is pressing down.

[0004] Therefore, the applicant proposes a temporary reinforcement and support device for coal mine roadways during coal mining and tunneling to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a temporary reinforcement support device for coal mine roadways during mining and tunneling, in order to solve the problems of existing temporary reinforcement support devices for coal mine roadways lacking a linkage mechanism for height adjustment and limit locking, requiring manual repeated hole drilling and force application for fixation, which is cumbersome and time-consuming; and being unable to achieve synchronous adaptation and locking when switching between different height sections, increasing labor intensity and prolonging the support response time when the roof is pressed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a temporary reinforcement and support device for coal mine roadways during coal mining and tunneling, comprising two telescopic rods, each of which has a connecting mechanism at its top. The connecting mechanism includes a housing, the bottom of which is fixedly connected to the top of the telescopic rod. The inner cavity of the housing is provided with two straight rods, one end of which is rotatably connected to an ear seat, and the bottom of the ear seat is slidably connected to the bottom of the inner cavity of the housing. Support frames are respectively provided on both sides of the telescopic rods, and a top frame rod is provided above the two corresponding support frames. The two ends of the top frame rod are respectively fixedly connected to the top of the corresponding support frame. Sliding sleeves are fitted on both sides of the outer surface of the top frame rod, and one side of the sliding sleeve is rotatably connected to the other end of the corresponding straight rod through an ear seat.

[0007] Two insertion holes are provided on the outer surface of the top frame rod. A limiting mechanism is provided on one side of the sliding sleeve. The limiting mechanism includes a vertical block. One side of the vertical block is fixedly connected to the outer surface of the sliding sleeve. An installation frame is fixedly connected to the bottom of the vertical block. L-shaped sliding grooves are respectively provided on the inner walls of both sides of the installation frame. A short block is provided in the inner cavity of the installation frame. A screw is rotatably connected to the top of the short block. The top of the screw extends through the corresponding vertical block to the top of the vertical block by thread. Side rods are rotatably connected to both sides of the short block. The two side rods are fixedly connected by a round rod. A roller is slidably connected to the inner cavity of the L-shaped sliding groove. One end of the roller is rotatably connected to one side of the corresponding side rod by a rotating shaft. A force-bearing rod is fixedly connected to the outer surface of the round rod. An insertion block is rotatably connected to the end of the force-bearing rod away from the round rod. The end of the insertion block away from the force-bearing rod is inserted into the corresponding insertion hole.

[0008] The lower part of the outer walls on both sides of the mounting frame is fixedly connected to slide rails, and the two sides of the insert block are slidably connected to one side of the corresponding slide rail.

[0009] Furthermore, a displacement block is fixedly connected to the bottom of the ear seat 1, a displacement groove is provided at the bottom of the inner cavity of the outer shell, the bottom of the displacement block is slidably connected to the inner cavity of the corresponding displacement groove, and a spring damper is provided between the two corresponding ear seats 1 and located in the inner cavity of the outer shell.

[0010] Furthermore, both ends of the spring damper are fixedly connected to one side of the corresponding lug.

[0011] Furthermore, the bottom of the screw is rotatably connected to the top of the corresponding short block via a pivot, and a handle is fixedly connected to the extended end of the screw.

[0012] Furthermore, the two ear seats are symmetrically distributed on both sides of the inner cavity of the outer shell.

[0013] Furthermore, the side of the insert block away from the insertion hole is rotatably connected to one end of the corresponding force-bearing rod via an ear seat. Balance slide rods are fixedly connected to both sides of the insert block, and the end of the balance slide rod away from the insert block is slidably connected to the inner cavity of the corresponding slide rail.

[0014] Furthermore, one side of the outer surface of the roller is in contact with the inner wall of the corresponding L-shaped groove.

[0015] Furthermore, one of the top frame rods has two snap-fit ​​mechanisms on its outer surface, each snap-fit ​​mechanism including a snap-fit ​​plate. The other top frame rod has two docking mechanisms on one side of its outer surface, each docking mechanism including a vertical plate. One end of the vertical plate has an adapter groove, and one end of the snap-fit ​​plate is inserted into the inner cavity of the corresponding adapter groove. One end of the snap-fit ​​plate and one end of the vertical plate are respectively fixedly connected to the outer surface of the corresponding top frame rod.

[0016] Furthermore, a plurality of slots are provided on one inner wall of the adapter groove and along the horizontal direction of the adapter groove. A guide rod is fixedly connected to one side of the card plate. A card block and a compression spring are sleeved on the outer surface of the guide rod. The other end of the card block is inserted into the inner cavity of the corresponding card slot.

[0017] Furthermore, one end of the compression spring abuts against one side of the corresponding locking block.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This solution, through the design of a connecting mechanism and a limiting mechanism, allows personnel to drive the short block downwards simply by rotating the handle. The block, via the trajectory conversion of the side rod and roller within the L-shaped groove, automatically pushes the insert block laterally into the insertion hole to lock it in place. This solves the problem of existing temporary reinforcement support devices for coal mine roadways lacking linkage in their adjustment components and requiring repeated manual force application to the holes. Simultaneously, the connecting mechanism can adaptively compensate for changes in the spacing of the roof support rods, ensuring connection stability. Utilizing the threaded transmission of the screw and the vertical block, combined with the trajectory constraint of the L-shaped groove, the single rotation is transformed into precise insertion of the insert block, avoiding the uncertainty of manual hole alignment, reducing labor intensity, and shortening the support response time when the roof pressure is applied. Furthermore, the locking plate of the locking mechanism, along with the vertical plate, adapter groove, locking block, and compression spring of the docking mechanism, allows for the rapid combination of multiple sets of temporary reinforcement support devices for coal mine roadways, improving adaptability and deployment efficiency under complex cross-sectional conditions.

[0020] By incorporating the outer shell, displacement groove, displacement block, and spring damper, when personnel adjust the distance between the two top support rods, the lug one drives the displacement block to slide along the displacement groove at the bottom of the outer shell cavity. The spring damper provides elastic restoring force and position holding force to the two lugs one, enabling the connecting mechanism to adaptively compensate for changes in the distance between the two top support rods, ensuring that the straight rod is always stably connected to the sliding sleeve and the outer shell. At the same time, the displacement groove constrains the sliding trajectory of the displacement block, preventing the lug one from tilting or dislodging within the outer shell cavity, ensuring that the connecting mechanism maintains structural alignment during distance adjustment. This solves the problem of difficulty in adjusting the distance between top support rods and unstable connection caused by the lack of flexible adaptable structure in existing temporary reinforcement support devices for coal mine roadways, and improves the ease of assembly and connection reliability of the device under different roadway cross-section working conditions.

[0033] As attached Figure 1 To be continued Figure 8 As shown:

[0034] Example 1:

[0035] This invention provides a temporary reinforcement and support device for coal mine roadways during coal mining and tunneling, comprising two telescopic rods 1, each with a connecting mechanism 2 at its top. The connecting mechanism 2 includes a housing 201, the bottom of which is fixedly connected to the top of the telescopic rod 1. The inner cavity of the housing 201 is provided with two straight rods 206, one end of which is rotatably connected to a lug 204, and the bottom of the lug 204 is slidably connected to the bottom of the inner cavity of the housing 201. Support frames 3 are provided on both sides of the telescopic rods 1, and a top frame rod 5 is provided on the top of the two corresponding support frames 3. The two ends of the top frame rod 5 are fixedly connected to the top of the corresponding support frame 3. Sliding sleeves 4 are fitted on both sides of the outer surface of the top frame rod 5, and one side of the sliding sleeve 4 is rotatably connected to the other end of the corresponding straight rod 206 through a lug 207.

[0036] Two insertion holes 9 are provided on the outer surface of the top support rod 5. A limiting mechanism 6 is provided on one side of the sliding sleeve 4. The limiting mechanism 6 includes a vertical block 601. One side of the vertical block 601 is fixedly connected to the outer surface of the sliding sleeve 4. A mounting frame 602 is fixedly connected to the bottom of the vertical block 601. L-shaped sliding grooves 606 are respectively provided on the inner walls of both sides of the mounting frame 602. A short block 605 is provided in the inner cavity of the mounting frame 602. A screw 603 is rotatably connected to the top of the short block 605. The top of the screw 603 extends through the corresponding vertical block 601 to the vertical block 601 via a thread. Above 01, side rods 608 are rotatably connected to both sides of the short block 605. The two side rods 608 are fixedly connected by a round rod 609. A roller 607 is slidably connected to the inner cavity of the L-shaped groove 606. One end of the roller 607 is rotatably connected to one side of the corresponding side rod 608 through a rotating shaft. A force-bearing rod 610 is fixedly connected to the outer surface of the round rod 609. An insert block 612 is rotatably connected to the end of the force-bearing rod 610 away from the round rod 609. The end of the insert block 612 away from the force-bearing rod 610 is inserted into the corresponding insertion hole 9.

[0037] The lower part of the outer walls on both sides of the mounting frame 602 is fixedly connected to slide rails 614, and the two sides of the insert block 612 are slidably connected to one side of the corresponding slide rail 614.

[0038] A displacement block 203 is fixedly connected to the bottom of the ear seat 204. A displacement groove 202 is provided at the bottom of the inner cavity of the outer shell 201. The bottom of the displacement block 203 is slidably connected to the inner cavity of the corresponding displacement groove 202. A spring damper 205 is provided between the two ear seats 204 and in the inner cavity of the outer shell 201.

[0039] Working principle: First, the bottom of the support frame 3 is brought into contact with the roadway floor. Simultaneously, the telescopic rod 1 is brought into contact with the ground, and the sliding sleeves 4 on both sides are positioned directly above the corresponding support frame 3. The top support rod 5 is then lifted until both ends are above the sliding sleeves 4, and then lowered so that the top support rod 5 passes through the inner cavity of the sliding sleeve 4 and enters the inner cavity of the support frame 3, where it is fixed with bolts. When adjusting the support height, the straight rod 206 is lifted, causing the sliding sleeve 4 to slide along the top support rod 5 to the appropriate position. The handle 604 is rotated to drive the screw 603 to rotate. Because the screw 603's thread passes through the vertical block 601, it drives the short block 605 to rotate. As the frame 602 moves downward, the side rod 608 rotates accordingly. The roller 607 moves along the L-shaped slide groove 606 and turns to lateral movement when it fits the bottom. The round rod 609 pushes the force rod 610, so that the insert block 612 is inserted into the insertion hole 9 to complete the locking under the cooperation of the balance slide rod 613 and the slide rail 614. When assembling the device, align the clamping plate 701 with the adapter groove 802, move the clamping block 704 to squeeze the compression spring 703 and push it into the adapter groove 802. Release the clamping block 704 so that it is inserted into the clamping groove 803 under the action of the compression spring 703 to complete the docking.

[0040] This solution, through the connection mechanism 2 and the limiting mechanism 6, allows personnel to rotate the handle 604 to drive the short block 605 downward. The side rod 608 and roller 607 then automatically push the insert block 612 laterally into the insertion hole 9 to lock it in place. This solves the problem of existing temporary reinforcement support devices for coal mine roadways lacking linkage in their adjustment components and requiring repeated manual force application to the holes. It achieves height adaptation and automatic locking simultaneously, shortening the support response time when the roof pressure is applied. Simultaneously, the screw 603 and the threaded transmission of the vertical block 601, combined with the trajectory constraint of the L-shaped slide 606, transforms simple rotation into precise insertion of the insert block 612, avoiding the uncertainty of manual hole alignment and reducing labor intensity. Furthermore, the locking plate 701 of the locking mechanism 7, in conjunction with the vertical plate 801, the adaptation groove 802, the locking block 704, and the compression spring 703 of the docking mechanism 8, allows multiple sets of temporary reinforcement support devices for coal mine roadways to be quickly combined, improving adaptability and deployment efficiency under complex cross-sectional conditions.

[0041] Example 2:

[0042] This embodiment is basically the same as the previous embodiment, except that the two ends of the spring damper 205 are fixedly connected to one side of the corresponding lug 204.

[0043] The bottom of the screw 603 is rotatably connected to the top of the corresponding short block 605 via a pivot, and a handle 604 is fixedly connected to the extended end of the screw 603.

[0044] Two earpieces 204 are symmetrically distributed on both sides of the inner cavity of the outer shell 201.

[0045] The side of the insert 612 away from the insertion hole 9 is rotatably connected to one end of the corresponding force rod 610 through the ear seat 611. The two sides of the insert 612 are respectively fixedly connected to the balance slide rod 613. The end of the balance slide rod 613 away from the insert 612 is slidably connected to the inner cavity of the corresponding slide rail 614.

[0046] One side of the outer surface of the roller 607 is in contact with the inner wall of the corresponding L-shaped groove 606.

[0047] Working Principle: Through the arrangement of ear seat 204, displacement block 203, outer shell 201, displacement groove 202, and spring damper 205, when the distance between the two top support rods 5 is adjusted, ear seat 204 drives displacement block 203 to slide along the displacement groove 202 at the bottom of the inner cavity of outer shell 201. Spring damper 205 provides elastic restoring force and position holding force to the two ear seats 204, enabling the connecting mechanism 2 to adaptively compensate for changes in the distance between the two top support rods 5. This ensures that the straight rod 206 is always stably connected to the sliding sleeve 4 and outer shell 201, preventing ear seat 204 from tilting or dislodging within the inner cavity of outer shell 201. It also ensures that the connecting mechanism 2 maintains structural alignment during distance adjustment, improving the ease of assembly and connection reliability of the temporary reinforcement support device for coal mine roadways under different roadway cross-section conditions. The spring damper 205 is fixedly connected at both ends to one side of the corresponding ear seat 204. When the distance between the two ear seats 204 changes due to variations in the distance between the top support rods 5... When relative displacement occurs, the spring damper 205 synchronously transmits elastic force through the fixed connection structure at both ends, ensuring that the force exerted by the spring damper 205 on the two lugs 204 is uniform and symmetrical. This prevents the displacement block 203 from getting stuck in the displacement groove 202 due to unilateral force on the lugs 204, further improving the smoothness and structural stability of the spacing adaptation process of the connecting mechanism 2. Through the rotatable connection between the bottom of the screw 603 and the top of the corresponding short block 605 via a rotating shaft, and the fixed connection of the handle 604 to the extension end of the screw 603, when the operator rotates the handle 604 to drive the screw 603 to rotate, the screw 603 drives the short block 605 to move vertically within the cavity of the mounting frame 602 via the rotating shaft. This accurately converts the rotation operation into the linear motion of the short block 605, preventing the short block 605 from shifting when the screw 603 rotates. This ensures the accuracy of the subsequent trajectory conversion between the side rod 608 and the roller 607, and improves the smoothness of the locking operation of the limit mechanism 6.

[0048] Example 3:

[0049] This embodiment is basically the same as the previous embodiment, except that two snap-fit ​​mechanisms 7 are provided on the outer surface of one of the top support rods 5, and the snap-fit ​​mechanism 7 includes a snap-fit ​​plate 701. Two docking mechanisms 8 are provided on one side of the outer surface of the other top support rod 5, and the docking mechanism 8 includes a vertical plate 801. One end of the vertical plate 801 is provided with an adapter groove 802. One end of the snap-fit ​​plate 701 is inserted into the inner cavity of the corresponding adapter groove 802. One end of the snap-fit ​​plate 701 and one end of the vertical plate 801 are respectively fixedly connected to the outer surface of the corresponding top support rod 5.

[0050] A plurality of slots 803 are provided on one side of the inner wall of the adapter slot 802 and along the horizontal direction of the adapter slot 802. A guide rod 702 is fixedly connected to one side of the card plate 701. A card block 704 and a compression spring 703 are sleeved on the outer surface of the guide rod 702. The other end of the card block 704 is inserted into the inner cavity of the corresponding slot 803.

[0051] One end of the compression spring 703 abuts against one side of the corresponding locking block 704.

[0052] Working principle: Two ear seats 204 are symmetrically distributed on both sides of the inner cavity of the outer shell 201. When the distance between the top support rods 5 is adjusted, the two ear seats 204 slide synchronously and symmetrically within the inner cavity of the outer shell 201. This ensures that the force center of the connecting mechanism 2 always coincides with the axis of the outer shell 201, preventing excessive displacement of one ear seat 204 and uneven force distribution within the inner cavity of the outer shell 201. It also ensures that the connection posture between the straight rod 206 and the sliding sleeve 4 is always perpendicular to the top support rod 5, preventing the sliding sleeve 4 from jamming when sliding along the top support rod 5. The side of the insert block 612 away from the insertion hole 9 is rotatably connected to one end of the corresponding force rod 610 via ear seat 611. Balance slide rods 613 are fixedly connected to both sides of the insert block 612, and the end of the balance slide rod 613 away from the insert block 612 is slidably connected to the inner cavity of the corresponding slide rail 614. When the force rod 610 pushes the insert block 612 to insert laterally... When inserting into the socket 9, the balance slide bar 613 slides along the inner cavity of the slide rail 614 and forms a guiding constraint on the insert block 612, ensuring that the insert block 612 makes a pure lateral linear motion, avoiding tilting or shaking of the insert block 612 during insertion into the socket 9, ensuring precise alignment of the insert block 612 and the socket 9, and improving the locking reliability and structural durability of the limiting mechanism 6. Through the setting that one side of the outer surface of the roller 607 is in contact with the inner wall of the corresponding L-shaped slide groove 606, when the short block 605 moves down and drives the side rod 608 to rotate, the roller 607 rolls along the predetermined trajectory of the L-shaped slide groove 606 and always remains in contact with the inner wall, eliminating the motion deviation caused by the gap between the roller 607 and the L-shaped slide groove 606, ensuring that the transition from vertical to lateral movement is continuous and impact-free, avoiding jamming or incomplete locking of the insert block 612, and improving the operating feel and locking accuracy of the limiting mechanism 6.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
