Description

Technical Field

[0001] This utility model relates to the technical field of underground safety equipment and devices, specifically to a support connecting rod on a temporary support frame for a mine monorail. Background Technology

[0002] Traditional monorail suspended temporary support equipment mainly consists of support beams, lifting frames, support frames, hydraulic pump stations, drive units, and other components, and is equipped with electrical and hydraulic control systems. Among these, the support frame, as the core load-bearing component, needs to support the weight of the support beams and lifting frames. It is usually rigidly connected to the hydraulic pump station to ensure overall integrity and must be able to move along the track to achieve overall equipment relocation. One of the core functions of the support frame is to provide stable support, preventing the equipment from tilting or sliding during loading or movement, thus ensuring the safety of personnel and equipment.

[0003] However, existing support frame structures still have significant limitations in achieving stable support: the support frame mainly relies on its connection with the track and pump station to provide stability, lacking an effective and adjustable lateral support structure to directly support the sides of the roadway; the roadway width is not completely uniform, and the lateral width of existing support frames is usually fixed, making it difficult to flexibly adapt to roadway cross-sections of different widths, which is the main problem currently faced. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a support connecting rod on a temporary support frame for mine monorail, so as to solve the problem that the support frame on the traditional monorail suspended temporary support equipment cannot provide a reliable support structure.

[0005] To solve the above problems, this utility model provides the following technical solution:

[0006] A support rod for a temporary monorail support frame in a mine; it includes a front cross arm and a rear cross arm arranged in parallel; a longitudinal support arm is installed between the front cross arm and the rear cross arm; the front cross arm is a hollow rectangular box structure, and both ends of the front cross arm are open structures along the transverse direction; a pair of adjustable-length transverse telescopic arms are installed in the inner cavity of the front cross arm; the extended ends of the two transverse telescopic arms are respectively set out from the open ends of the front cross arm, and telescopic support legs are rotatably installed on the extended ends of the transverse telescopic arms; a telescopic support is rotatably installed on the top surface of the longitudinal support arm; a carrier support is also provided on the front end face of the front cross arm.

[0007] Preferably, two pairs of positioning flange plates are provided on the opposite end faces of the front and rear cross arms; there are two longitudinal support arms, and the front and rear ends of the two longitudinal support arms are respectively mounted on the positioning flange plates by bolt assemblies.

[0008] Preferably, a support leg connecting block is installed on the extended end of the lateral telescopic arm; one end of the telescopic support leg is hinged to the support leg connecting block; a first telescopic rotating rod is hinged to the upper part of the support leg connecting block; an ear plate with a through hole is installed at the upper part of the middle of the telescopic support leg; the other end of the first telescopic rotating rod is hinged to the through hole on the ear plate; the rotation of the telescopic support leg relative to the lateral telescopic arm is controlled by the telescopic movement of the first telescopic rotating rod.

[0009] Furthermore, the outrigger connecting block is a hollow block structure similar to an L-shape, with one end set along the horizontal plane where the front and rear cross arms are located, and the other end set vertically downward; one end of the telescopic outrigger is hinged to the horizontal end of the outrigger connecting block, and one end of the first telescopic rotating rod is hinged to the included angle position on the outrigger connecting block.

[0010] Preferably, a support connecting block is provided in the middle of the longitudinal support arm; the telescopic support is hinged to the support connecting block; a second telescopic rotating rod is hinged to the upper part of the support connecting block; an ear plate with a through hole is installed in the middle of the telescopic support; the other end of the second telescopic rotating rod is hinged to the through hole on the ear plate; the rotation of the telescopic support relative to the longitudinal support arm is controlled by the telescopic movement of the second telescopic rotating rod.

[0011] Furthermore, the support connecting block is an L-shaped hollow block structure; one end is set along the horizontal plane where the front and rear cross arms are located, and the other end is set vertically upward; one end of the telescopic support is hinged to the vertically upward end of the support connecting block, and one end of the second telescopic rotating rod is hinged to the horizontal end of the support connecting block.

[0012] Preferably, an inclined support plate is provided at the top of the telescopic support; and several anti-slip pins are provided on the inclined support plate.

[0013] Preferably, the support for the vehicle is a cantilevered flat plate component arranged in a horizontal direction, with a positioning through hole in the middle of the support; a hinge seat is installed at the positioning through hole; and a rib is also provided between the bottom surface of the support and the front cross arm.

[0014] The beneficial effects of this utility model are reflected in the following aspects:

[0015] 1. Provides reliable lateral support and enhances overall stability: The telescopic boom inside the front crossarm and the telescopic outriggers with adjustable angle enable the equipment to flexibly adapt to roadway cross sections of different widths; the telescopic outriggers can precisely abut against the two sides of the roadway to form active lateral support, effectively preventing the equipment from tilting or sliding, and significantly improving operational safety.

[0016] 2. Enables rapid and precise adjustment of the top support point:

[0017] The telescopic support controls its pitch angle through the second telescopic rotating rod. Combined with the height adjustment capability of the longitudinal support arm, it can be quickly adjusted in multiple degrees of freedom to deal with uneven roof conditions. The design of the inclined support plate and the anti-slip pin further enhances the fit and anti-slip properties of the roof contact, ensuring effective transmission of support force.

[0018] 3. Optimize the dynamic connection stability with the moving mechanism:

[0019] The support for the carrier adopts a hinged seat structure and is reinforced with ribs, which makes the connection between the support frame and the drive unit (carrier trolley) both flexible and rigid. This design can effectively absorb the complex stress in dynamic displacement, reduce the risk of loosening of connection points, and improve the overall structural reliability of the equipment.

[0020] 4. Modular design enhances maintainability and adaptability, with high structural integration and convenient and efficient operation: Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] Example:

[0026] Reference Figure 1 This embodiment provides a support connecting rod on a temporary support frame for a mine monorail; it includes a front cross arm 1 and a rear cross arm 2 arranged in parallel; a longitudinal support arm 3 is installed between the front cross arm 1 and the rear cross arm 2; the front cross arm 1 is a hollow rectangular box structure, and both ends of the front cross arm 1 are open structures along the transverse direction; a pair of adjustable transverse telescopic arms 4 are installed in the inner cavity of the front cross arm 1; the extended ends of the two transverse telescopic arms 4 are respectively set out from the open ends of the front cross arm 1, and telescopic support legs 5 are rotatably installed on the extended ends of the transverse telescopic arms 4; a telescopic support 6 is rotatably installed on the top surface of the longitudinal support arm 3; a carrier support 7 is also provided on the front end face of the front cross arm 1.

[0027] Two pairs of positioning flange plates 8 are provided on the opposite end faces of the front crossarm 1 and the rear crossarm 2; there are two longitudinal support arms 3, and the front and rear ends of the two longitudinal support arms 3 are respectively installed on the positioning flange plates 8 by bolt assemblies. This flange connection method provides a stable support frame, and also facilitates on-site assembly, disassembly and maintenance. If necessary, the installation position of the longitudinal support arms 3 can be adjusted or support arms of different specifications can be replaced to meet specific needs.

[0028] A support leg connecting block 9 is installed on the extended end of the transverse telescopic arm 4; one end of the telescopic support leg 5 is hinged to the support leg connecting block 9; a first telescopic rotating rod 10 is hinged to the upper part of the support leg connecting block 9; an ear plate with a through hole is installed at the upper middle part of the telescopic support leg 5; the other end of the first telescopic rotating rod 10 is hinged to the through hole on the ear plate; the rotation of the telescopic support leg 5 relative to the transverse telescopic arm 4 is controlled by the extension and retraction of the first telescopic rotating rod 10. By controlling the extension and retraction of the first telescopic rotating rod 10, the angle of the telescopic support leg 5 when in contact with the roadway sidewall can be precisely adjusted to ensure that the support surface can be tightly and stably pressed against the potentially uneven roadway wall.

[0029] The outrigger connecting block 9 is an L-shaped hollow block structure, with one end positioned along the horizontal plane of the front crossarm 1 and the rear crossarm 2, and the other end vertically downwards. One end of the telescopic outrigger 5 is hinged to the horizontal end of the outrigger connecting block 9, while one end of the first telescopic rotating rod 10 is hinged to the included angle position on the outrigger connecting block 9. This L-shaped design optimizes the force transmission path, effectively transferring the lateral support force generated by the telescopic outrigger 5 to the main structure of the transverse telescopic arm 4 and the front crossarm 1, while providing a suitable installation position and lever point for the first telescopic rotating rod 10.

[0030] A support connecting block 11 is provided in the middle of the longitudinal support arm 3; a telescopic support 6 is hinged to the support connecting block 11; a second telescopic rotating rod 12 is hinged to the upper part of the support connecting block 11; an ear plate with a through hole is installed in the middle of the telescopic support 6; the other end of the second telescopic rotating rod 12 is hinged to the through hole on the ear plate; the rotation of the telescopic support 6 relative to the longitudinal support arm 3 is controlled by the telescopic movement of the second telescopic rotating rod 12. The telescopic drive of the second telescopic rotating rod 12 allows the upper end of the telescopic support 6 to be adjusted in pitch angle, which is crucial for adapting to different inclination angles or local unevenness of the roadway roof, ensuring the effective contact area of ​​the supported roof.

[0031] The support connecting block 11 is an L-shaped hollow block structure; one end is set along the horizontal plane where the front cross arm 1 and the rear cross arm 2 are located, and the other end is set vertically upward; one end of the telescopic support 6 is hinged to the vertically upward end of the support connecting block 11, and one end of the second telescopic rotating rod 12 is hinged to the horizontal end of the support connecting block 11. This L-shaped structure stably transmits the vertical support force of the telescopic support 6 to the longitudinal support arm 3, and provides a horizontal mounting base for the second telescopic rotating rod 12, forming a stable triangular adjustment mechanism.

[0032] An inclined support plate 13 is provided at the top of the telescopic support 6; several anti-slip pins 14 are provided on the inclined support plate 13. The anti-slip pins 14 can support the slab rock, significantly enhance the friction and anti-slip ability of the contact surface, and prevent the support point from sliding under pressure.

[0033] The support 7 is a horizontally oriented cantilevered flat plate component with a positioning through hole in its center. A hinge seat is installed at this positioning through hole. Ribs are also provided between the lower surface of the support 7 and the front crossarm 1. The hinge seat design allows for a certain degree of relative swing freedom between the support vehicle and the support frame in the vertical plane, which is very beneficial for buffering stress and preventing rigid deformation or damage to structural components when the equipment moves on uneven tracks. The ribs greatly enhance the rigidity and bending and torsional resistance of the cantilever section of the support 7, ensuring that the connection point with the drive unit remains stable and reliable even under dynamic loads.

[0034] When using the utility model device in this embodiment, the following process can be referred to:

[0035] S1. Initial positioning: The entire temporary support equipment is moved along a single track to the work position in the roadway where support is required by the carrier vehicle.

[0036] S2. Adjust the support width: Operate the control device to drive the two transverse telescopic arms 4 inside the front cross arm 1 to extend outward synchronously until the telescopic outriggers 5 at their extended ends are roughly aligned with the sidewalls on both sides of the roadway. Precisely adjust the extension length of the two transverse telescopic arms 4 according to the actual width of the roadway so that the telescopic outriggers 5 on both sides have sufficient travel to contact the roadway sidewalls;

[0037] S3. Deploy and adjust the outrigger angle: Operate the control device to extend the telescopic outriggers 5 on both sides downwards. At the same time, adjust the extension amount of the first telescopic rotating rod 10 on the corresponding side to drive the telescopic outrigger 5 to rotate around its hinge point with the outrigger connecting block 9, and adjust its angle with the horizontal plane so that the outrigger plate at its end can adapt to the inclination angle or surface condition of the roadway wall; continue to extend the telescopic outrigger 5 until it is firmly pressed against the side walls of the roadway at an appropriate angle, providing reliable lateral support.

[0038] S4. Adjust the top support: Operate the control device to extend the telescopic support 6 upwards; at the same time, adjust the extension amount of the second telescopic rotating rod 12 to drive the telescopic support 6 to rotate around its hinge point with the support connecting block 11, changing the inclination angle of the inclined support plate 13 at its top, so that it is as parallel as possible to the roadway roof or reaches the best fit; continue to extend the telescopic support 6 until the anti-slip pin 14 on the inclined support plate 13 tightly abuts against and partially embeds into the roof, providing stable vertical support force;

[0039] S5. Equipment Relocation: When it is necessary to move the support equipment, operate the control device to retract the telescopic support 6, telescopic outriggers 5, and lateral telescopic arm 4 in sequence. After confirming that all movable parts have been safely retracted, operate the drive unit to move the entire equipment to the next working position, and then repeat steps 2-4 for support.
