DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example

[0029] Please refer to Figures 1 to 6 The present embodiment provides a reinforcement device for tunnel engineering, comprising a plurality of pairs of first support beams 10 and second support beams 20 of the same length, wherein a lower slot 11 is provided at the bottom of the middle portion of the first support beam 10, and an upper slot 21 is provided at the top of the middle portion of the second support beam 20. The first support beam 10 and the corresponding second support beam 20 are movably connected through the lower slot 11 and the upper slot 21, and the middle portions of the first support beam 10 and the corresponding second support beam 20 are connected through a rotating shaft 12 so that the first support beam 10 and the second support beam 20 are axially connected. It is connected in an X-shaped rotation; the second includes a plurality of vertically arranged lifting columns 30, and each of the two ends of the first support beam 10 or the second support beam 20 is symmetrically connected to a lifting column 30; the third includes a plurality of compensation parts 40, which are arranged on the top surfaces of the first support beam 10 and the second support beam 20 at intervals along the length direction, and the compensation parts 40 include a telescopic part 41 provided on the first support beam 10 or the second support beam 20 and an extrusion part 42 provided on the telescopic part 41, and the telescopic part 41 can make the extrusion part 42 abut against the top surface of the tunnel.

[0030] The reinforcement device for tunnel engineering provided in this embodiment is provided with a pair of first support beams 10 and second support beams 20, and respectively opens a lower slot 11 and an upper slot 21 in the two, and provides a rotating shaft 12 so that the two form an X-shaped rotating connection structure with the rotating shaft 12 as the axis, so as to adapt to tunnels of different widths by adjusting the angle between the first support beam 10 and the second support beam 20; by providing a lifting column 30, the first support beam 10 and the second support beam 20 are supported and can be raised to contact the top surface of the tunnel; by providing a compensating member 40, which is spaced apart along the length direction of the first support beam 10 and the top surface of the second support beam 20. When the first support beam 10 and the second support beam 20 rise to contact the tunnel top surface, the extrusion member 42 is pushed out in the direction of the tunnel top surface through the telescopic member 41, so that the top surface of the first support beam 10 or the second support beam 20 is in contact with the tunnel top surface through the extrusion member 42, so as to effectively cope with the uneven tunnel top surface; through the mutual cooperation of the above-mentioned features, the reinforcement device for tunnel engineering can effectively solve the problem that the length of the top beam cannot be adaptively adjusted according to the actual width of the tunnel, and the top beam cannot form a relatively uniform and effective structural support with the tunnel top surface during the excavation process.

[0031] In order to further optimize the structure so that the first support beam 10 and the second support beam 20 do not affect each other's normal contact with the tunnel top surface, when the first support beam 10 and the second support beam 20 are movably plugged into the lower slot 11 and the upper slot 21, the top surface of the first support beam 10 is flush with the top surface of the second support beam 20.

[0032] In order to cope with the curved tunnel top surface, the first support beam 10 and the second support beam 20 are curved beams of the same shape with a convex middle portion.

[0033] In order to further explain the specific structure of the compensation member 40, the telescopic member 41 is a hydraulic rod, and the extrusion member 42 is arranged at one end of the telescopic member 41; the end of the telescopic member 41 away from the extrusion member 42 is rotatably connected to the first support beam 10 or the second support beam 20.

[0034] Through the above-mentioned arrangement, the thrust of the hydraulic rod is utilized to make the extrusion member 42 approach and contact the tunnel top surface. By arranging the telescopic member 41 to be rotatably connected with the first support beam 10 or the second support beam 20, the extrusion member 42 can make adaptive rotation according to the specific conditions of the tunnel top surface when in contact with the tunnel top surface, so as to further improve the fit between the two.

[0035] To further explain the specific structure of the extrusion member 42 , the extrusion member 42 includes a stacked elastic support layer 421 and a buffer layer 422 . The side of the elastic support layer 421 away from the buffer layer 422 is vertically connected to the telescopic member 41 .

[0036] By setting up an elastic support layer 421, strong structural support is provided. The elastic support layer 421 can be made of an elastic metal plate or alloy plate, or a wooden board. By setting up a buffer layer 422, the hard-hard contact between the elastic support layer 421 and the tunnel top surface is converted into a soft-hard contact, so as to further improve the support performance and structural performance. The buffer layer 422 can be made of a plastic metal plate or alloy plate, or made of materials such as hard rubber.

[0037] In order to facilitate adjustment of the opening and closing angle of the X-shaped structure formed by the first support beam 10 and the second support beam 20 according to the width of the tunnel, a moving wheel 31 is provided at the bottom end of the lifting column 30 .

[0038] Through the above arrangement, the user can indirectly adjust the opening and closing angle of the X-shaped structure formed by the first support beam 10 and the second support beam 20 by horizontally pushing and pulling the lifting column 30. During this process, the moving wheel 31 improves the smoothness of movement between the bottom of the lifting column 30 and the ground.

[0039] In order to further lock the opening and closing angles of the X-shaped structure formed by the first support beam 10 and the second support beam 20, the above-mentioned reinforcement device for tunnel engineering also includes a pair of parallel rails 50, and the two rails 50 are symmetrically laid on both sides of the width direction of the tunnel ground; the top surface of the rail 50 is provided with a wheel groove 51 along the length direction that matches the width of the moving wheel 31.

[0040] Through the above arrangement, the spacing between the two rails 50 matches the width of the tunnel, and then the position of the moving wheel 31 is limited by the wheel groove 51 on the top surface of the rail 50, thereby limiting the opening and closing angle of the X-shaped structure to avoid unnecessary changes in the opening and closing angle of the X-shaped structure during the support process.

[0041] In order to fix the position of the reinforcement device after it moves along the track 50 to the position requiring reinforcement to prevent it from continuing to slide along the track 50, a plurality of brake hydraulic rods 32 are vertically provided on the side wall at the bottom of the lifting column 30. The bottom end of the brake hydraulic rod 32 is provided with a support plate 33. The support plate 33 is used to contact and squeeze the top surface of the track 50 to disengage the moving wheel 31 from the wheel groove 51.

[0042] Through the above arrangement, when braking is required, it is only necessary to push the support plate 33 downward through the brake hydraulic rod 32, so that the support plate 33 contacts and squeezes the top surface of the track 50, thereby causing the moving wheel 31 to rise and disengage from the wheel groove 51, so that the relative position of the reinforcement device and the track 50 can be effectively fixed.

[0043] In order to further improve the lateral limiting degree of the reinforcement device and the track 50 and prevent the reinforcement device from laterally separating from the track 50, a limiting ridge 52 is provided on the top surface of the track 50 along the length direction; a limiting plate 331 is vertically provided on the outer side of the support plate 33, and when the moving wheel 31 slides with the wheel groove 51, the limiting plate 331 contacts the side wall surface of the limiting ridge 52.

[0044] In order to further enhance the integrity of the reinforcement device, each pair of the first support beam 10 and the second support beam 20 forms an X-shaped unit; the two lifting columns 30 located on the same side of each unit are connected by a telescopic plate 60, and the telescopic plate 60 includes a slidably plugged motherboard 61 and a sub-plate 62; the two lifting columns 30 located on the same side of two adjacent units are connected by a fixed plate 63; the telescopic plate 60 and the fixed plate 63 are both horizontally arranged on the upper part of the lifting columns 30 and are both arranged parallel to the track 50.

[0045] It should be noted that the telescopic plate 60 and the fixed plate 63 may be connected to the lifting column 30 in the form of an axis hinge to cope with the possibility of a curvature of the tunnel.

[0046] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
