Description

Technical Field

[0001] This invention relates to the field of support device technology, specifically a temporary reinforcement support device for roadways. Background Technology

[0002] Coal mines, as an important energy source, are widely used in industrial production and other fields. Since coal mines are generally located underground, mining operations are also underground. When mining underground, coal mine roadways are generally used for material transportation and personnel access. The stability of coal mine roadways is the foundation for ensuring mining safety. Therefore, after the roadway is excavated, it needs to be reinforced with retaining structures to ensure the stability of the roadway. Before the construction of the support structure, temporary support devices can be used to increase the support of the roadway. Once the subsequent support is stable, they can be removed.

[0003] The temporary reinforcement and support devices currently in use have relatively simple structures, focusing on reinforcing the top of the roadway while lacking support for the sides. This results in an incomplete support system for the roadway and poses significant safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a temporary reinforcement and support device for roadways to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A connecting hinge plate is fixedly provided on the second limiting plate, and the connecting hinge plate is hinged to the upper end of the outward pushing rod.

[0010] Preferably, there are two movable support plates, symmetrically arranged at both ends of the support frustum. Limiting connection grooves are symmetrically formed on both sides of the end face of the movable support plate away from the hydraulic jack. A matching movable groove is formed on the movable support plate between the limiting connection grooves. The movable connecting column is inserted into the limiting connection groove. A lower support plate is fixedly provided at the lower end of the movable support plate. A threaded through hole is formed in the middle of the lower support plate. First support rods are symmetrically fixedly provided on both sides of the end face of the movable support plate near the hydraulic jack. The first support rods are inserted into support connection holes. Insertion receiving holes are symmetrically formed on both sides of the lower end of the movable support plate, and the insertion receiving holes penetrate the first support rods.

[0011] Preferably, there are two sidewall support plates, which are respectively installed on the movable support plate, and second support rods are symmetrically fixed on the end face of the sidewall support plate near the movable support plate. The second support rods are inserted into the insertion sockets. There are two support moving blocks, which are respectively installed on the movable support plate.

[0012] Preferably, the supporting movable block has a hinge groove and a second bearing hole at its lower end. A matching movable block is fixedly installed at one end of the supporting movable block near the movable support plate. The matching movable block is inserted into the matching movable groove. Supporting side plates are symmetrically fixedly installed on both sides of the upper end of the supporting movable block. A supporting hollow column is welded onto the supporting side plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0015] 1. When supporting the tunnel, place the support platform in the tunnel, then start the hydraulic jack to move the top arc-shaped support plate upward, thereby supporting the inner top surface of the tunnel. As it moves upward, it works in conjunction with the rack and pinion to drive the gears, which in turn move the two movable support plates towards the tunnel sidewalls, facilitating the support of the tunnel sidewalls. When not supporting the tunnel, the top arc-shaped support plate and the movable support plates are in a retracted state, making it easy to transport and store the entire device. When in use, the top arc-shaped support plate and the movable support plates can be unfolded simultaneously, which is very convenient and quick.

[0016] 2. A side wall support plate is provided on the movable support plate. The side wall support plate can be adjusted independently to adapt to roadways of different widths. During adjustment, simply rotate the threaded rotating rod to move the support moving block upward. Then, under the action of the hinged connecting rod, the side wall support plate can be moved towards the side wall of the roadway, thus providing close support to the side wall. In addition, as the support moving block moves upward, the auxiliary support cylinder will contact the top arc-shaped support plate, and the support spring will be in a compressed state. This provides auxiliary support for the top arc-shaped support plate, further consolidating the support of the top arc-shaped support plate for the roadway. Attached Figure Description

[0025] Please see Figures 1 to 6 The present invention provides a technical solution:

[0026] A temporary roadway reinforcement support device includes a support frustum 1. A hydraulic jack 11 is fixedly installed at the center of the upper end of the support frustum 1. A top arc-shaped support plate 12 is fixedly installed at the upper end of the hydraulic jack 11. A lower protruding connecting block 13 is fixedly installed at the middle of the lower end of the top arc-shaped support plate 12. The lower end of the lower protruding connecting block 13 is fixedly connected to the hydraulic jack 11.

Two support connecting holes 18 are symmetrically opened on the H-shaped frame 16 below the first bearing holes 17. A roadway sidewall auxiliary support mechanism is provided on the support frustum 1.

[0027] The auxiliary support mechanism for the roadway sidewall includes a mating gear 2, a movable connecting column 3, a movable support plate 4, a sidewall support plate 5, a support moving block 6, a threaded rotating rod 7, an auxiliary support plate 8, a support spring 83, and a hinged mating rod 9.

[0028] A support shaft 21 is symmetrically fixed on both sides of the gear 2. A first bearing 22 is sleeved on the support shaft 21 and installed in the first bearing hole 17. An outward push rod 23 is fixedly installed on the support shaft 21 and a movable connecting column 3 is hinged to the upper end of the outward push rod 23.

[0029] One end of the movable connecting column 3 is fixedly provided with a first limiting plate 31, and the other end of the movable connecting column 3 is fixedly provided with a second limiting plate 32. A connecting hinge plate 33 is fixedly provided on the second limiting plate 32, and the connecting hinge plate 33 is hinged to the upper end of the outward pushing rotating rod 23.

[0030] Two movable support plates 4 are symmetrically arranged at both ends of the support frustum 1. Limiting connection grooves 41 are symmetrically opened on both sides of the end face away from the hydraulic jack 11 on the movable support plate 4. A matching movable groove 42 is opened on the movable support plate 4 between the limiting connection grooves 41. The movable connecting column 3 is inserted into the limiting connection groove 41, and the diameter of the movable connecting column 3 is equal to the width of the limiting connection groove 41. A lower support plate 43 is fixedly arranged at the lower end of the movable support plate 4. A threaded through hole 44 is opened in the middle of the lower support plate 43. A first support rod 45 is symmetrically fixed on both sides of the end face of the movable support plate 4 near the hydraulic jack 11. The first support rod 45 is inserted into the support connection hole 18. Insertion receiving holes 46 are symmetrically opened on both sides of the lower end of the movable support plate 4. The insertion receiving holes 46 penetrate the first support rod 45.

[0031] There are two side wall support plates 5, which are respectively installed on the movable support plate 4. A second support rod 51 is symmetrically fixed on the end face of the side wall support plate 5 near the movable support plate 4. The second support rod 51 is inserted into the insertion socket 46. There are two support moving blocks 6, which are respectively installed on the movable support plate 4. The diameter of the second support rod 51 is equal to the diameter of the insertion socket 46.

[0032] The supporting movable block 6 has a hinge groove 61 and a second bearing hole 62 at its lower end. A mating movable block 63 is fixedly installed on one end of the supporting movable block 6 near the movable support plate 4. The mating movable block 63 is inserted into the mating movable groove 42 and the width of the mating movable block 63 is equal to the width of the mating movable groove 42. Supporting side plates 64 are symmetrically fixed on both sides of the upper end of the supporting movable block 6, and a supporting hollow column 65 is welded on the supporting side plate 64.

[0033] A second bearing 71 is installed in the second bearing hole 62. The second bearing 71 is fitted with a threaded rotating rod 7, which is threaded into the threaded through hole 44. A connecting rod 82 is inserted into the hollow support column 65. The connecting rod 82 is fixedly set on the lower end face of the auxiliary support plate 8. An auxiliary support cylinder 81 is fixedly set on the upper end of the auxiliary support plate 8. A support spring 83 is sleeved on the connecting rod 82. The two ends of the support spring 83 are respectively welded to the lower end face of the auxiliary support plate 8 and the hollow support column 65. A hinged fitting rod 9 is hinged in the hinge groove 61. The upper end of the hinged fitting rod 9 is hinged to the side wall support plate 5.

[0034] During tunnel support, the support platform 1 is placed inside the tunnel. Then, the hydraulic jack 11 is activated, causing the top arc-shaped support plate 12 to move upwards until it contacts the inner top surface of the tunnel, thus providing support. As the top arc-shaped support plate 12 moves upwards, it, under the action of the rack 15, drives the gear 2 to rotate. The rotation of the gear 2 drives the outward push rod 23 downwards, which in turn moves the movable connecting column 3 downwards, pushing the movable support plate 4 towards the tunnel sidewall for subsequent sidewall support. Alternatively, when not supporting the tunnel, the top arc-shaped support plate 12, movable support plate 4, and sidewall support plate 5 are all stored around the hydraulic jack 11 for easy storage and transportation. After the movable support plate 4 is unfolded, the sidewall support plate 5 installed on it can be... Individually adjustable to accommodate tunnels of varying widths, the screw-driven rotating rod 7 moves upwards under the action of the screw thread, which in turn moves the support moving block 6 upwards. This, in turn, pushes the sidewall support plate 5 towards the tunnel sidewall under the action of the hinged connecting rod 9, until it supports the sidewall and provides protection. Furthermore, as the support moving block 6 moves upwards, the auxiliary support cylinder 81 contacts the lower end face of the top arc-shaped support plate 12. The cylindrical surface of the auxiliary support cylinder 81 fits better with the arc surface of the top arc-shaped support plate 12, providing better auxiliary support. As the support moving block 6 moves upwards, the support spring 83 is compressed, thus maintaining an upward force on the auxiliary support cylinder 81, reinforcing the top arc-shaped support plate 12. This is highly practical.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
