Description

Technical Field

[0001] This invention relates to the field of observation marker installation technology, and in particular to a rapid deployment device for monitoring settlement points on the tunnel arch. Background Technology

[0002] In the monitoring and measurement of tunnel arch settlement, the most commonly used method is to use a total station. The corresponding traditional method of setting up monitoring points involves erecting scaffolding, ladders, or using elevated work platforms such as street light trucks or lifting platforms to reach the required height on the tunnel arch before drilling or attaching monitoring points. Therefore, there is an urgent need for a simplified device for rapid deployment of monitoring points.

[0003] Some existing technologies are simpler, such as using extended support rods to attach reflective patches to the tunnel arch. However, this requires placing each reflective patch on the top of the support rod, which necessitates lowering the support rod back and forth, making it inconvenient to operate. Furthermore, the protective paper for each patch needs to be peeled off and discarded carelessly, creating a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid deployment device for monitoring settlement points on the tunnel arch.

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

[0006] A rapid deployment device for monitoring settlement points in a tunnel arch includes a support rod. A storage box is fixedly connected to the upper end of the support rod. The upper end of the storage box has an open structure and a storage cavity. Multiple marking plates are stacked inside the storage cavity. An electric push rod is fixedly connected to the bottom of the storage box. The telescopic rod of the electric push rod extends into the storage cavity and is fixedly connected to a push plate. A support plate is fixedly connected to the inner arc surface of the storage box. A drive motor is fixedly connected to the support plate. The main shaft of the drive motor has a round rod, and the end of the round rod has a round roller.

[0007] Each marking plate has an adhesive layer on its upper side, a release liner on its upper side, and an adhesive clip on its upper side. An adhesive component is fixedly connected to the outside of the roller, and the adhesive component and the adhesive clip are set accordingly.

[0008] Preferably, the adhesive fastener is a Velcro velvet surface, and the outer circle of the adhesive piece is fixedly connected to the Velcro hook surface.

[0009] Preferably, the adhesive clip is a rubber rod with a dovetail cross section, the bottom of the marking plate is provided with an avoidance groove, the avoidance groove is set corresponding to the rubber rod, the adhesive component is a rubber plate, the rubber plate is provided with a slot, the slot is set corresponding to the rubber rod, two rubber rods are provided, two rubber plates are provided and evenly distributed on the outer circle of the roller, and the arc length between the two rubber plates is equal to the distance between the two rubber rods.

[0010] Preferably, a waste box is fixedly connected to one side of the storage box, and the upper end of the waste box has an open structure.

[0011] Preferably, the roller is rotatably connected to the rod and is provided with a torsion spring, and the outer circumference of the roller is provided with a rubber pressure layer.

[0012] Preferably, the round rod is hollow and has a slider slidably connected inside. The round rod has through grooves on its upper and lower sides, which are connected to the inner cavity of the round rod. A vertical rod is fixedly connected to the upper and lower sides of the slider. The vertical rods are slidably connected to the through grooves one by one. Each vertical rod is fixedly connected to a pin on the side facing the round roller. The pins are set with corresponding slots. A pushing device is provided on the upper side of the waste box. The pushing device is used for the vertical rods to slide along the through grooves.

[0013] Preferably, the pushing device includes a vertical rod, which is fixedly connected to the upper outer side of the waste box. A horizontal bar is fixedly connected to the upper end of the vertical rod, and an inclined bar is fixedly connected to the bottom of the horizontal bar. A roller is rotatably connected to the upper vertical rod, and the roller can roll to the side of the inclined bar. A support spring is fixedly connected between the slider and the inner wall of the end of the round rod cavity.

[0014] Preferably, a triangular plate is fixedly connected to the bottom of the inclined rod, and an arc-shaped groove is provided at intervals at the bottom of the triangular plate. A rubber pad is fixedly connected in the arc-shaped groove, and the round rod is vertically hinged to the main shaft of the drive motor and is provided with a first torsion spring.

[0015] Preferably, a handle is fixedly connected to the bottom of the support rod, and an operation button is provided on the handle.

[0016] The advantages of this invention are as follows: The rapid deployment device for settlement monitoring points on the tunnel arch provided by this invention allows workers to use a support rod and an operation button. First, an electric push rod pushes the top layer of stacked marker plates to the opening at the top of the storage box. Then, a drive motor rotates the marker plates via a roller to adhere the release paper to the upper side of the marker plates, facilitating their removal. Subsequently, the electric push rod further adheres the marker plates with the release paper removed to the tunnel arch. There is no need to refill the marker plates, allowing them to be set at intervals on the tunnel arch, thereby improving the rapid installation of settlement monitoring points.

[0017] This invention uses a push pin to insert into a slot to fix the rubber rod out. The rubber rod serves as the main fulcrum and rigid support point for the rolled-up release paper. Thus, the release paper, which is wrapped but does not contact the outer circle of the roller, can be easily separated by the push-out action of the push pin, making it easier to collect the release paper in the waste box.

[0018] Furthermore, when the round rod rotates to the bottom of the triangular plate, the inclined surface at the bottom of the triangular plate causes the round rod to rotate downwards and tilt, facilitating the sliding of the release paper. Combined with the round rod falling into the arc-shaped groove and the resetting action of the first torsion spring, vibration is generated, thereby cleaning the release paper and preventing it from remaining on the roller. This ensures the reliable performance of the device. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] like Figure 1-6 As shown, the present invention provides a rapid deployment device for monitoring settlement points in tunnel arches, comprising a support rod 1, a storage box 2 fixedly connected to the upper end of the support rod 1, the upper end of the storage box 2 having an open structure, the storage box 2 having a storage cavity, a plurality of marking plates 3 stacked inside the storage cavity, the bottom of the marking plates 3 having positioning points for measuring elevation, an electric push rod 21 fixedly connected to the bottom of the storage box 2, the telescopic rod of the electric push rod 21 extending into the storage cavity and fixedly connected to a push plate, a support plate 5 fixedly connected to the inner arc surface of the storage box 2, a drive motor 6 fixedly connected to the support plate 5, the main shaft of the drive motor 6 having a round rod 7, and a round roller 8 at the end of the round rod 7;

[0027] Each marking plate 3 has an adhesive layer on its upper side, a release paper 31 on the upper side of the adhesive layer, and an adhesive clip on the upper side of the release paper 31. An adhesive component is fixedly connected to the outer side of the roller 8, and the adhesive component and the adhesive clip are set accordingly.

[0028] The bottom of the support rod 1 is fixedly connected to the handle 11, and the handle 11 is equipped with an operation button 12. The operation button 12 is used to control the corresponding functions of the drive motor 6 and the electric push rod 21.

[0029] This invention allows workers to hold a support rod 1 and use an operation button 12. First, an electric push rod 21 pushes the top layer of stacked marker plates 3 to the upper opening of the storage box 2. Then, a drive motor 6 rotates the roller 8 to the top of the marker plate 3, adhering the release paper 31 on the top of the marker plate 3 for easy removal. The electric push rod 21 then further adheres the top layer of marker plates 3 with the release paper removed to the tunnel arch. The marker plates 3 with the release paper removed are stuck to the tunnel arch, while the lower marker plates 3 fall back down with the electric push rod 21. There is no need to refill the marker plates 3, so that marker plates 3 can be set at intervals on the tunnel arch, thereby improving the rapid installation of settlement monitoring points.

[0030] After one marker board 3 is pasted, the push plate of the electric push rod 21 descends, and the stacked marker boards 3 also descend to the initial position, thus completing the preparation for pasting the next marker board 3.

[0031] Example 2

[0032] The adhesive fastener is a Velcro velvet surface, and the outer circle of the adhesive piece is fixedly connected to the Velcro hook surface; in use, the roller 8 rolls to the upper side of the release paper 31 through the rotation of the rod 7, and removes the release paper 31. Then, the electric push rod 21 sticks the mark plate 3 with only the adhesive layer left on the upper side to the bottom of the tunnel arch.

[0033] Example 3

[0034] In Embodiment 2, the release paper 31 is removed using Velcro. However, the Velcro hook and loop fasteners have many connection points, making it difficult to push the release paper 31 off by the roller 8. Generally, only an electric push rod and scraper can remove the release paper 31. After repeated use, torn release paper 31 remains on the roller 8, affecting the removal of the release paper 31 from the subsequent marking plate 3. This necessitates removal and cleaning, which is inconvenient. Therefore, this embodiment discloses an improved solution, as follows:

[0035] The adhesive fastener is a dovetail-shaped rubber rod 32. The bottom of the marking plate 3 is provided with a relief groove 311, which is set corresponding to the rubber rod 32. The adhesive component is a rubber plate 33, which is provided with a slot 34, which is set corresponding to the rubber rod 32. Two rubber rods 32 are provided, and two rubber plates 33 are provided and evenly distributed on the outer circle of the roller 8. The arc length between the two rubber plates 33 is equal to the distance between the two rubber rods 32. The drive motor 6 is a servo motor, and its rotation angle can be precisely controlled and set. After the drive motor 6 drives the roller 8 to rotate at a precisely controlled angle, the roller 8 rolls the same number of times within the same angle, thereby achieving the positioning and engagement of the rubber rod 32 and the rubber plate 33.

[0036] The circular roller 8 is rotatably connected to the circular rod 7 and is provided with a rotary torsion spring. The outer circle of the circular roller 8 is provided with a rubber pressure contact layer.

[0037] The storage box 2 is fixedly connected to the waste box 9 on one side, and the upper end of the waste box 9 has an open structure.

[0038] In this embodiment, after the roller 8 rolls onto the marking plate 3, its rubber contact layer forms a compression, so that when the round rod 7 carries the roller 8 past the top of the marking plate 3, the roller 8 rolls automatically. The first rubber plate 33 on the outer circle of the rolling roller 8 rolls and presses against the first rubber rod 32, forming an elastic engagement. Then the roller 8 rolls up, wrapping the release paper 31 around the roller 8, and it is secured to the roller 8 by the elastic engagement of the second rubber plate 33 and the second rubber rod 32. This makes it easier for the roller 8 to transfer the waste release paper 31 to the waste box 9 for centralized collection, avoiding the random disposal of scattered waste release paper 31 in the tunnel and preventing adverse effects.

[0039] During the process of transferring the release paper 31, after the roller 8 leaves the marking plate 3, the rotary torsion spring 81 causes the roller 8 to return to its initial position and discharge the waste release paper 31 above the waste box 9. Then, the roller 8 rotates back to its initial position with the rod 7 and resets. The above action is repeated, so that the rubber plate 33 of the roller 8 can be elastically fastened to the rubber rod 32 each time, which facilitates the setting of marking plates 3 at intervals on the tunnel arch, thereby improving the rapid installation of settlement monitoring points.

[0040] Example 4

[0041] Using existing technology, it's easy to imagine using an electric pusher to push the release paper 31 off the roller 8. However, this method has two drawbacks: firstly, it may not completely remove the release paper, leaving residue; secondly, while it can be achieved through a control program, it requires sensors and a more complex control program design. To reduce the failure rate and simplify the design, this embodiment provides a structure that automatically removes waste release paper 31, as follows:

[0042] Specifically, the round rod 7 is hollow and internally connected to the slider 71. The round rod 7 has through grooves 72 on its upper and lower sides, which are connected to the inner cavity of the round rod 7. The upper and lower sides of the slider 71 are respectively fixedly connected to a vertical rod 73. The vertical rods 73 and the through grooves 72 are slidably connected in a one-to-one correspondence. Each vertical rod 73 is fixedly connected to a pin 74 on the side facing the round roller 8. The pins 74 are set in the corresponding slots 34. The waste box 9 is provided with a pushing device on its upper side. The pushing device is used for the vertical rods 73 to slide along the through grooves 72.

[0043] The pushing device includes a vertical rod 75, which is fixedly connected to the upper outer side of the waste box 9. A horizontal bar 76 is fixedly connected to the upper end of the vertical rod 75, and a diagonal bar 77 is fixedly connected to the bottom of the horizontal bar 76. A roller 78 is rotatably connected to the upper vertical rod 73, and the roller 78 can roll to the side of the diagonal bar 77. A support spring 79 is fixedly connected between the slider 71 and the inner wall of the end of the round rod 7.

[0044] Furthermore, the bottom of the inclined rod 77 is fixedly connected to a triangular plate 771, and the bottom of the triangular plate 771 is provided with an arc-shaped groove 772 at intervals. A rubber pad is fixedly connected in the arc-shaped groove 772. The round rod 7 is vertically hinged to the main shaft of the drive motor 6 and is provided with a first torsion spring.

[0045] After the roller 8 rolls up the release paper 31 and transfers it above the waste box 9, the rod 7 passes by the side of the inclined rod 77. Since the distance from one end of the inclined rod 77 to the rotation axis of the rod 7 is less than that of the other end, the vertical rod 73 and the roller 78 roll to the side of the triangular plate 771, so that the vertical rod 73 slides along the through groove 72 and enters the slot 34 through the ejector pin 74 to fix the rubber rod 32. The rubber rod 32 serves as the main fulcrum and rigid support point of the rolled-up release paper 31. Thus, the release paper 31, which is wrapped but does not contact the outer circle of the roller 8, can be easily separated by the ejection action of the ejector pin 74, so that the release paper 31 can be easily collected in the waste box 9.

[0046] Furthermore, since the rolled-up release paper 31 has a certain depth on the roller 8, when the round rod 7 rotates to the bottom of the triangular plate 771, the inclined surface at the bottom of the triangular plate 771 causes the round rod 7 to rotate downward and tilt, making it easier for the release paper 31 to slide off. Combined with the round rod 7 falling into the arc-shaped groove 772 and the reset action of the first torsion spring, vibration is generated, thereby cleaning the release paper 31 separately and avoiding the release paper 31 remaining on the roller 8, thus making the device reliable.

[0047] 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.
