Description

Technical Field

[0001] The utility model relates to the technical field of tunnel reinforcement, in particular to a grouting reinforcement device. Background Art

[0002] During the tunnel construction process, a specific double-pressure shield method is used for excavation, and the segmented grouting technology is combined for stratum reinforcement and water stopping. When metal segmented grouting is used, pipe clamps and pipe racks are required to reinforce the grouting pipeline.

[0003] However, the prior art has the following disadvantages when used: when performing segmented glue injection, the grouting pipeline is usually placed on the ground, but there are relatively sharp stones on the ground. When the grouting pipeline comes into contact with these sharp stones, it is easy to wear, which is not conducive to extending the service life of the grouting pipeline. In addition, the existing equipment for reinforcing the grouting pipeline needs to be used in conjunction with the size of the grouting pipeline, resulting in a limited scope of application. Therefore, a grouting reinforcement equipment is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when performing segmented glue injection work, the grouting pipeline is usually placed on the ground, but there are relatively sharp stones on the ground. When the grouting pipeline comes into contact with these sharp stones, it is easy to wear and tear, which is not conducive to extending the service life of the grouting pipeline. In addition, the existing equipment for reinforcing the grouting pipeline needs to be used in conjunction with the size of the grouting pipeline, resulting in a problem of limited scope of application.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a grouting reinforcement device, comprising: a pipe rack, the inner wall of which is slidably mounted with a plurality of telescopic columns, and further comprising:

[0006] A base, fixedly mounted on one end of the plurality of telescopic columns located on the pipe rack, wherein the outer surfaces of the plurality of telescopic columns are provided with a plurality of limiting holes;

[0007] Two inner cavities are provided at one end of the pipe rack near the limiting hole, and T-shaped frames are slidably mounted on the tops of the two inner cavities;

[0008] Two sets of steel wire ropes are respectively fixedly installed on one end of the two T-shaped frames close to the base, and one end of the two sets of steel wire ropes away from the T-shaped frames is fixedly installed with a limit block;

[0009] The two groups of springs are respectively fixedly mounted on one end of the two groups of limit blocks located inside the inner cavity, and the two groups of springs are fixedly mounted on one end away from the limit blocks with a hollow block.

[0010] Preferably, outer surfaces of the two groups of hollow blocks are respectively fixedly mounted on inner walls of the two inner cavities, and one end of the two groups of limit blocks located outside the inner cavities is respectively slidably connected to inner walls of the plurality of limit holes.

[0011] The technical effect of adopting the above further scheme is: the staff holds the top of the pipe rack with his hands and pulls the T-frame with his fingers, and the T-frame drives the wire rope to move. When the wire rope moves, it drives the limit block to retract into the inner cavity, and when the limit block moves, it compresses the spring 1 fixed on the hollow block, and when the limit block is retracted into the inner cavity, it is separated from the limit hole, and the telescopic column is no longer restricted by the limit block, so the pipe rack is lifted up, and the base and the telescopic column will not move with the pipe rack due to the influence of gravity. When the pipe rack reaches the required height, the fingers release the T-frame, and the T-frame no longer pulls the wire rope and the limit block. When the spring 1 is not under force, the limit block is pushed out from the inner cavity to the limit hole, and the limit block restricts the telescopic column again, so as to enhance the stability of the pipe rack after height adjustment, and to keep the pipe rack away from sharp objects on the ground, so as to avoid contact with sharp objects when the grouting pipeline is placed inside the pipe rack, and to protect the grouting pipeline and extend its service life.

[0012] Preferably, a bidirectional threaded rod is installed at one end of the pipe rack close to the base through a bearing, and moving blocks are threadedly installed at both ends of the bidirectional threaded rod.

[0013] The technical effect of adopting the above further solution is that the staff rotates the bidirectional threaded rod to drive the moving blocks at both ends thereof to move relative to each other.

[0014] Preferably, one end of the two moving blocks away from the bidirectional threaded rod is fixedly mounted with a U-shaped block, and one end of the two U-shaped blocks close to the moving block is slidably connected to the outer surface of the pipe rack.

[0015] The technical effect of adopting the above further solution is that when the two moving blocks move, they drive the U-shaped block and the buffer pad to move relative to each other, which makes it easier to clamp and fix the grouting pipeline in the pipe rack.

[0016] Preferably, buffer pads are fixedly installed on opposite sides of the two U-shaped blocks, and a ratchet is fixedly sleeved on one end of the bidirectional threaded rod that passes through the pipe rack to the outside.

[0017] The technical effect of adopting the above further solution is: the setting of the buffer pad facilitates the buffering and protection of the grouting pipeline, and the ratchet is driven to rotate when the bidirectional threaded rod rotates.

[0018] Preferably, a pawl is meshingly connected to the outer surface of the ratchet, and a connecting rod is rotatably mounted on one end of the pawl away from the ratchet.

[0019] The technical effect of adopting the above further solution is that when the ratchet wheel rotates, the pawl is driven to move, and the pawl is connected to the connecting rod through the second spring, so that the pawl and the ratchet wheel are easily engaged.

[0020] Preferably, one end of the connecting rod away from the pawl is fixedly mounted on one end of the pipe rack, and one end of the connecting rod close to the pawl is fixedly mounted with a second spring.

[0021] The technical effect of adopting the above further solution is: one end of the second spring is fixed to the pawl and the other end is fixed to the connecting rod, so as to enhance the stability of the second spring.

[0022] Preferably, the other end of the second spring is fixedly mounted on the outer surface of the pawl, and a pull rod is fixedly mounted on one end of the pawl away from the connecting rod.

[0023] The technical effect of adopting the above further solution is: pulling the pull rod temporarily disengages the pawl from the ratchet wheel, thereby facilitating the rotation of the bidirectional threaded rod.

[0024] Compared with the prior art, the advantages and positive effects of the utility model are:

[0025] 1. In the utility model, when in use, the spring pushes the limit block from the inner cavity to the inner limit hole when no force is applied, and the limit block limits the telescopic column again, so as to enhance the stability of the pipe rack after the height is adjusted, and to keep the pipe rack away from sharp objects on the ground, so as to avoid the grouting pipeline from contacting with sharp objects when it is placed inside the pipe rack, and to protect the grouting pipeline and extend its service life.

[0026] 2. In the utility model, when in use, the two moving blocks drive the U-shaped block and the buffer pad to move relative to each other, which is convenient for clamping and fixing the grouting pipeline in the pipe rack, enhancing the stability of the reinforcement of the grouting pipeline, and playing a buffering role at the same time. The distance between the two buffer pads can be adjusted as needed, which is convenient for adapting to different sizes of grouting pipelines, which is beneficial to improving the application range of this reinforcement equipment.

[0032] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0034] Embodiment 1, as Figure 1 - Figure 4 As shown, the utility model provides a grouting reinforcement device, including: a pipe rack 1, a plurality of telescopic columns 2 are slidably mounted on the inner wall of the pipe rack 1, and also includes:

[0035] A base 3 is fixedly mounted on one end of a plurality of telescopic columns 2 located at the pipe rack 1, and a plurality of limiting holes 4 are provided on the outer surfaces of the plurality of telescopic columns 2;

[0036] Two inner chambers 5 are provided at one end of the pipe rack 1 close to the limiting hole 4, and a T-shaped frame 7 is slidably mounted on the top of the two inner chambers 5;

[0037] Two sets of steel wire ropes 8 are respectively fixedly mounted on one end of two T-shaped frames 7 close to the base 3, and one end of the two sets of steel wire ropes 8 away from the T-shaped frames 7 is fixedly mounted with a limit block 6;

[0038] The two groups of springs 9 are respectively fixedly mounted on one end of the two groups of limit blocks 6 located inside the inner cavity 5, and the ends of the two groups of springs 9 away from the limit blocks 6 are both fixedly mounted with hollow blocks 10.

[0039] In the present embodiment, when in use, the staff holds the top of the pipe rack 1, pulls the T-shaped frame 7 with fingers, and the T-shaped frame 7 drives the steel wire rope 8 to move. When the steel wire rope 8 moves, the limit block 6 is retracted into the inner cavity 5. When the limit block 6 moves, it compresses the spring 9 fixed on the hollow block 10. When the limit block 6 is retracted into the inner cavity 5, it is separated from the limit hole 4, and the telescopic column 2 is no longer restricted by the limit block 6. The pipe rack 1 is lifted up, and the base 3 and the telescopic column 2 will not move with the pipe rack 1 due to the influence of gravity. When the pipe rack 1 reaches the required height, the fingers release the T-shaped frame 7, the T-shaped frame 7 no longer pulls the steel wire rope 8 and the limit block 6, and the spring 9 is not under force. The limit block 6 is pushed out from the inner cavity 5 to the inner limit hole 4, and the limit block 6 restricts the telescopic column 2 again, which is convenient for enhancing the stability of the pipe rack 1 after the height is adjusted, and is conducive to keeping the pipe rack 1 away from sharp objects on the ground, and is convenient for the grouting pipeline to avoid contact with sharp objects when it is placed in the pipe rack 1, which is conducive to protecting the injection pipeline and extending its service life.

[0040] Embodiment 2, as Figure 1 - Figure 4 As shown, the outer surfaces of the two groups of hollow blocks 10 are fixedly mounted on the inner walls of the two inner cavities 5, respectively, and the ends of the two groups of limit blocks 6 located outside the inner cavity 5 are slidably connected to the inner walls of the plurality of limit holes 4. A bidirectional threaded rod 101 is installed through a bearing at one end of the pipe rack 1 close to the base 3, and moving blocks 102 are threadedly installed at both ends of the bidirectional threaded rod 101. U-shaped blocks 103 are fixedly mounted on the ends of the two moving blocks 102 away from the bidirectional threaded rod 101, and the ends of the two U-shaped blocks 103 close to the moving blocks 102 are slidably connected to the outer surface of the pipe rack 1. Buffer pads 104 are fixedly mounted on the opposite sides of the two U-shaped blocks 103, and a ratchet 105 is fixedly sleeved on one end of the bidirectional threaded rod 101 that passes through the pipe rack 1 to the outside. A ratchet 107 is meshedly connected to the outer surface of the ratchet 105, and a connecting rod 106 is rotatably mounted on the end of the ratchet 107 away from the ratchet 105. One end of the connecting rod 106 away from the pawl 107 is fixedly mounted on one end of the pipe rack 1, and one end of the connecting rod 106 close to the pawl 107 is fixedly mounted with a spring 2 108. The other end of the spring 2 108 is fixedly mounted on the outer surface of the pawl 107, and one end of the pawl 107 away from the connecting rod 106 is fixedly mounted with a pull rod 109.

[0041] In this embodiment, when in use, the staff rotates the bidirectional threaded rod 101 to drive the moving blocks 102 at both ends thereof to move relative to each other. When the two moving blocks 102 move, they drive the U-shaped block 103 and the buffer pad 104 to move relative to each other, which is convenient for clamping and fixing the grouting pipeline in the pipe rack 1, enhancing the stability of the reinforcement of the grouting pipeline, and playing a buffering role at the same time. When the bidirectional threaded rod 101 rotates, it drives the ratchet 105 to rotate, and when the ratchet 105 rotates, it drives the pawl 107 to move, and the pawl 107 is connected to the connecting rod 108 through the spring 108. The rod 106 is connected to facilitate the engagement of the pawl 107 with the ratchet 105. The pawl 107 prevents the ratchet 105 from rotating, which is convenient for enhancing the stability of the two-way threaded rod 101 after rotation, and further improving the stability of the reinforced grouting pipeline. The pull rod 109 is pulled so that the pawl 107 is temporarily not engaged with the ratchet 105, which is convenient for rotating the two-way threaded rod 101. The distance between the two buffer pads 104 can be adjusted as needed, which is convenient for adapting to the sizes of different grouting pipelines, which is beneficial to improving the scope of application of the reinforcement equipment.

[0042] Working principle: When in use, the staff holds the top of the pipe rack 1, pulls the T-shaped frame 7 with their fingers, and the T-shaped frame 7 drives the wire rope 8 to move. When the wire rope 8 moves, it drives the limit block 6 to retract into the inner cavity 5. When the limit block 6 moves, it compresses the spring 9 fixed on the hollow block 10. When the limit block 6 retracts into the inner cavity 5, it separates from the limit hole 4. The telescopic column 2 is no longer restricted by the limit block 6. The pipe rack 1 is lifted up, and the base 3 and the telescopic column 2 will not move with the pipe rack 1 due to the influence of gravity. The pipe rack 1 reaches the required height. When the height of the pipe rack 1 is adjusted, the fingers release the T-shaped frame 7, and the T-shaped frame 7 no longer pulls the wire rope 8 and the limit block 6. When the spring 9 is not under force, the limit block 6 is pushed out from the inner cavity 5 to the inner limit hole 4, and the limit block 6 limits the telescopic column 2 again, which is convenient for enhancing the stability of the pipe rack 1 after the height adjustment, and is conducive to keeping the pipe rack 1 away from sharp objects on the ground, so that the grouting pipeline can be placed inside the pipe rack 1 to avoid contact with sharp objects, which is conducive to protecting the grouting pipeline and extending its service life. When in use, the staff turns the two-way screw The threaded rod 101 drives the moving blocks 102 at both ends thereof to move relative to each other. When the two moving blocks 102 move, they drive the U-shaped block 103 and the buffer pad 104 to move relative to each other, so as to clamp and fix the grouting pipeline in the pipe rack 1, enhance the stability of the reinforcement of the grouting pipeline, and play a buffering role at the same time. When the bidirectional threaded rod 101 rotates, it drives the ratchet 105 to rotate. When the ratchet 105 rotates, it drives the pawl 107 to move. The pawl 107 is connected to the connecting rod 106 through the spring 108. The pawl 107 is engaged with the ratchet 105, and the pawl 107 prevents the ratchet 105 from rotating, so as to enhance the stability of the bidirectional threaded rod 101 after rotation, and further improve the stability of the reinforced grouting pipeline. The pull rod 109 is pulled so that the pawl 107 is temporarily not engaged with the ratchet 105, so as to facilitate the rotation of the bidirectional threaded rod 101. The distance between the two buffer pads 104 can be adjusted as needed, so as to adapt to different sizes of grouting pipelines, which is beneficial to improving the scope of application of the reinforcement equipment.
