Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a tunnel lining spray curing device. Background Technology

[0002] After tunnel excavation, the original balance of the surrounding strata is disrupted, causing tunnel deformation or collapse. To protect the stability of the surrounding rock and ensure traffic safety, the tunnel must have a support structure of sufficient strength. Tunnel lining is a permanent support structure constructed along the perimeter of the tunnel using materials such as reinforced concrete to prevent deformation or collapse of the surrounding rock.

[0003] To ensure the stability of the lining, construction workers use a curing device to spray and cure the lining.

[0004] For example, patent CN221119996U discloses "A Tunnel Lining Maintenance Device," see [link to patent]. Figure 1 The patent includes a moving mechanism 1, which is equipped with a spray frame 2, a water tank 3 and a water pump 4. The spray frame 2 is arched and has multiple spray holes along its outer contour. The water tank 3 is connected to the input end of the water pump 4 and the output end of the water pump 4 is connected to the spray frame 2.

[0005] During maintenance, the moving mechanism 1 moves to the designated position, and the water in the water storage tank 3 is transported to the spray frame 2 by the water pump 4. The water entering the spray frame 2 is sprayed out through the spray holes to moisten the lining.

[0006] In the aforementioned patent, only the spray frame 2 itself is equipped with spray holes, resulting in a small spray range. How to expand the spray range and improve the spray efficiency is a technical problem that needs to be solved. Utility Model Content

[0007] To address the aforementioned shortcomings of existing technologies, this invention proposes a tunnel lining spray curing device. This invention not only expands the spraying range and improves spraying efficiency, but also facilitates storage.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A tunnel lining spray curing device includes a moving mechanism with an arched spray frame on the moving mechanism. Multiple spray pipes are arranged circumferentially on the inner side of the spray frame. One end of each spray pipe is rotatably connected to the spray frame. Multiple nozzles are arranged along the long side of each spray pipe, and a water inlet is provided at the end of each spray pipe. The moving mechanism includes an adjusting seat and a driving assembly. An arched support frame is provided on the adjusting seat. The driving assembly drives the adjusting seat to move axially along the spray frame. When the spray pipes are rotated to a horizontal position, the support frame abuts against the bottom of the spray pipes. When all the spray pipes are rotated to the same plane, the long side of each spray pipe extends radially along the spray frame.

[0010] Furthermore, the spray pipe has a water inlet at one end that is rotatably connected to the spray frame.

[0011] Furthermore, the drive assembly includes a drive motor, the output shaft of which is provided with a screw, and the adjusting seat is provided with a through screw hole. The screw is threadedly connected to the screw hole, and the adjusting seat is slidably connected to the moving mechanism.

[0012] Furthermore, the moving mechanism includes a mounting platform with rollers at the bottom and a groove in the middle. The groove has an opening at its front end, and the screw and the adjusting seat are located inside the groove. The adjusting seat slides in the groove, and the top surface of the adjusting seat is flush with the top surface of the mounting platform. The front end of the adjusting seat enters and exits through the opening. The supporting frame is located on the top surface of the front end of the adjusting seat, and the drive motor is located on the rear side of the mounting platform.

[0013] Furthermore, the front end of the adjustment seat is provided with an auxiliary seat, and the bottom of the auxiliary seat is provided with auxiliary wheels.

[0014] Furthermore, both the rollers and the auxiliary wheels are omnidirectional wheels.

[0015] The beneficial effects of this utility model are:

[0016] 1. Because multiple nozzles are installed on the spray pipe, the spraying range can be increased and the spraying efficiency can be improved when all the spray pipes are turned to a horizontal position.

[0017] 2. Because all the spray pipes can be rotated from the horizontal direction to the same plane, the axial length of the entire device can be avoided, the volume of the entire device can be reduced, and it is easier to store.

[0018] 3. Adjusting the spray pipe posture is simple; it only requires rotating the spray pipe and adjusting the position of the support frame using the drive component, which helps improve adjustment efficiency.

[0019] 4. By setting an auxiliary seat at the front end of the adjusting seat, the entire device can be stabilized when the adjusting seat moves out of the groove, which helps to improve the stability of the entire device. Attached Figure Description

[0038] Example:

[0039] See Figures 2-8 A tunnel lining spray curing device includes a moving mechanism 1, a spray frame 2, a spray pipe 5, a drive assembly 6, an adjustment seat 7, and a support frame 8.

[0040] See Figure 2 and Figure 3 The moving mechanism 1 includes a mounting platform 11 and rollers 12. The rollers 12 are mounted on the bottom of the mounting platform 11. The rollers 12 can be casters. The mounting platform 11 has a groove 111 in the middle and an opening 112 at the front end of the groove 111.

[0041] See Figure 2 and Figure 6 The spray frame 2 is arched and is mounted on the mounting platform 11. Multiple spray pipes 5 are provided on the inner circumference of the spray frame 2. One end of the spray pipe 5 is rotatably connected to the spray frame 2. Multiple nozzles 51 are provided on the long side of the spray pipe 5. A water inlet 52 is provided at the end of the spray pipe 5 that is rotatably connected to the spray frame 2. The water inlet 52 is used to connect to a water source.

[0042] See Figure 8 When all the spray pipes 5 are rotated to the same plane, the long side of the spray pipe 5 extends radially along the spray frame 2.

[0043] See Figure 7 The water source can be water stored in a water storage tank 3, which is placed on the mounting platform 11. The water storage tank 3 is installed together with the input end of the water pump 4. The output end of the water pump 4 is equipped with a water delivery pipe 41, which has one inlet and multiple outlets. The inlet is installed at the output end of the water pump 4, and each outlet is connected to the inlet 52 of a spray pipe 5. After the water pump 4 is started, the water in the water storage tank 3 is sprayed out from the nozzle 51 through the water pump 4, the water delivery pipe 41, and the spray pipe 5 in sequence. To increase the water storage capacity, two water storage tanks 3 can be placed on the mounting platform 11, and the bottoms of the two water storage tanks 3 are connected by a connecting pipe 31.

[0044] See Figure 5The drive assembly 6 includes a drive motor 61 and a screw 62. The drive motor 61 may be a servo motor. The housing of the drive motor 61 is mounted on the rear side of the mounting platform 11. The output end of the drive motor 61 extends into the groove 111, and the screw 62 is mounted on the output end of the drive motor 61, which is located within the groove 111. The drive motor 61 is used to drive the screw 62 to rotate.

[0045] See Figure 2 and Figure 3 An adjusting seat 7 is located within a groove 111, and a threaded hole 71 is provided through the adjusting seat 7. A screw 62 is threadedly connected to the threaded hole 71, and the adjusting seat 7 slides within the groove 111. The top surface of the adjusting seat 7 is flush with the top surface of the mounting platform 11. An auxiliary seat 72 is mounted at the front end of the adjusting seat 7, and an auxiliary wheel 73, which is a caster wheel, is mounted at the bottom of the auxiliary seat 72. When the drive motor 61 drives the screw 62 to rotate forward, the front end of the adjusting seat 7 extends out from the opening 112; when the drive motor 61 drives the screw 62 to rotate in reverse, the front end of the adjusting seat 7 retracts into the groove 111. The direction of movement of the adjusting seat 7 is also the axial direction of the arched spray frame 2.

[0046] The support frame 8 is also arched and is installed on the top front end of the adjusting seat 7. When the spray pipe 5 is rotated to a horizontal position, the support frame 8 abuts against the bottom of the spray pipe 5, so that the horizontal spray pipe 5 is supported by the support frame 8.

[0047] The working principle of this embodiment is as follows:

[0048] During maintenance, (1) the construction personnel move the moving mechanism 1 to the designated position; (2) the construction personnel turn the spray pipe 5 to a horizontal position; (3) the construction personnel start the drive motor 61, the drive motor 61 drives the screw 62 to rotate forward, so that the adjusting seat 7 drives the support frame 8 to move forward, the support frame 8 abuts against the bottom of the spray pipe 5, so that the horizontal spray pipe 5 is supported by the support frame 8, and then the drive motor 61 is turned off; (4) the construction personnel connect the external water source to the spray pipe 5, and the water entering the spray pipe 5 is sprayed out through the nozzle 51 to moisten and maintain the lining.

[0049] When storing, the drive motor 61 drives the screw 62 to reverse, and the adjusting seat 7 drives the support frame 8 to move backward, so that the support frame 8 moves to the rear side of the spray frame 2. Then, the construction personnel rotate all the spray pipes 5 to the same plane, at which time the long side of all the spray pipes 5 extends radially along the spray frame 2.

[0050] Based on the above working principle, it can be concluded that:

[0051] Because multiple nozzles 51 are installed on the spray pipe 5, the spraying range can be increased and the spraying efficiency can be improved when all the spray pipes 5 are turned to the horizontal position.

[0052] Furthermore, since all the spray pipes 5 can be rotated from the horizontal direction to the same plane, the axial length of the entire device can be avoided by the spray pipes 5, the volume of the entire device can be reduced, and it is easier to store.

[0053] In this device, adjusting the attitude of the spray pipe 5 is simple; it only requires rotating the spray pipe 5 and adjusting the position of the support frame 8 using the drive component 6, which helps to improve the adjustment efficiency.

[0054] By setting an auxiliary seat 72 at the front end of the adjusting seat 7, the entire device can be stabilized when the adjusting seat 7 moves out of the groove 111, which helps to improve the stability of the entire device.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
