Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and more specifically to a working platform for installing anchor bolts in tunnels. Background Technology

[0002] Anchor bolts are a type of rod system used for reinforcing soil and rock masses. Through the longitudinal tensile force of the anchor bolt, they overcome the disadvantage that the tensile strength of soil and rock masses is far lower than their compressive strength. On the surface, they restrict the soil and rock masses from detaching from the original mass, but macroscopically, they increase the cohesion of the soil and rock masses.

[0003] Currently, during tunnel construction, anchor bolts need to be installed to reinforce the stability of the tunnel. Construction workers usually install the anchor bolts in the tunnel using an installation platform. However, some anchor bolts need to be tilted at a certain angle during installation, requiring construction workers to hold the anchor bolts by hand, which is very troublesome. In addition, the tunnel ground may be uneven, and the installation platform may tilt when placed in the tunnel, affecting the installation of the anchor bolts, which is very inconvenient. Therefore, a working platform for installing anchor bolts in tunnels is proposed to solve the above problems. Summary of the Invention

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a working platform for installing anchor bolts in tunnels, including an installation platform, a handle fixedly connected to the right side of the installation platform, a position adjustment component and an angle adjustment component provided at the upper end of the installation platform, the angle adjustment component being disposed on the position adjustment component, and a lifting component provided at the lower end of the installation platform.

[0005] The beneficial effects of this invention are:

[0006] This invention, by incorporating a position adjustment component and an angle adjustment component, allows for rapid adjustment of the installation angle and position of the anchor bolt. It is simple to operate, saves manpower, and is convenient for construction personnel. Furthermore, the lifting component ensures that the installation platform remains level according to the terrain, facilitating the installation of the anchor bolt.

[0007] Furthermore, the angle adjustment component includes a mounting plate, and multiple sets of mounting plates are provided on the upper end of the mounting platform. A mounting column is rotatably connected to the rear side of the upper end of the mounting plate, and a first connecting rod is rotatably connected to the front side of the mounting column. A first threaded rod is threadedly connected to the middle of the other end of the first connecting rod, and a first knob is fixedly connected to the front end of the first threaded rod. The first threaded rod is rotatably connected to the mounting plate, and the mounting plate is connected to the position adjustment component.

[0008] The beneficial effect of the above-mentioned further solution is that by turning the first knob, the first knob drives the first threaded rod to rotate, which in turn drives the first connecting rod to move, and the first connecting rod pulls the mounting column, causing the mounting column to tilt.

[0009] Furthermore, the position adjustment component includes a second slide groove and a second threaded rod. The upper end of the mounting platform is provided with the second slide groove, and the second threaded rod is provided in the second slide groove. The front end of the second threaded rod is fixedly connected to a second knob, and the angle adjustment component is threadedly connected to the second threaded rod.

[0010] The beneficial effect of the above-mentioned further solution is that by turning the second knob, the second knob drives the second threaded rod to rotate, causing the angle adjustment component to slide in the second slide groove, thereby adjusting the position of the angle adjustment component.

[0011] Furthermore, a first sliding groove is provided in the middle of the mounting plate, and a first slider that cooperates with the first sliding groove is rotatably connected to the middle of the other end of the first connecting rod. The first slider is threadedly connected to the first threaded rod, and the first threaded rod is rotatably connected to the inner wall of the first sliding groove.

[0012] The beneficial effect of the above-mentioned further solution is that it makes the movement of the first connecting rod driven by the first threaded rod more stable during the rotation process.

[0013] Furthermore, the mounting post has a mounting groove in the middle, a threaded hole in the rear side, and a third threaded rod that mates with the threaded hole is threadedly connected to the rear side of the mounting post.

[0014] The beneficial effect of the above-mentioned further solution is that the anchor rod is inserted into the installation groove and fastened by the third threaded rod, which facilitates the quick installation and removal of the anchor rod.

[0015] Furthermore, the lifting assembly includes support members and adjusting members respectively located at the four corners of the lower end of the mounting platform. The support member includes a support column fixedly connected to the lower end of the mounting platform. A rod is inserted into the middle of the support column. A slot that cooperates with the rod is opened in the middle of the support column. A base is fixedly connected to the lower end of the rod. The adjusting member is connected to the rod and is used to drive the rod to move vertically.

[0016] Furthermore, the adjusting component includes a second connecting rod rotatably connected to the end of the insertion rod, the other end of the second connecting rod being threadedly connected to a fourth threaded rod, a third knob being fixedly connected to the outer side of the fourth threaded rod, and the fourth threaded rod being rotatably connected to the lower end of the mounting platform.

[0017] The beneficial effects of the above-mentioned further solution are as follows: by turning the third knob, the third knob drives the fourth threaded rod to rotate, which in turn drives the second connecting rod to move, causing the second connecting rod to push the insertion rod out of the slot, thereby adjusting the extension length of the insertion rod to support the mounting platform. Furthermore, multiple sets are set up, and the extension length of each set of insertion rods can be adjusted individually. The extension length of each set of insertion rods can be adjusted according to the terrain, ensuring that the mounting platform is always in a horizontal state, which facilitates the installation of anchor bolts.

[0018] Furthermore, a third sliding groove is provided at the lower end of the mounting platform, and a second slider that cooperates with the third sliding groove is rotatably connected to the end of the second connecting rod. The second slider is threadedly connected to a fourth threaded rod, and the fourth threaded rod is rotatably connected to the inner wall of the third sliding groove.

[0019] The beneficial effect of the above-mentioned further solution is that it makes the movement of the second connecting rod more stable during the rotation of the fourth threaded rod.

[0020] Furthermore, a mounting block is fixedly connected to the lower end of the support column, and a caster wheel is fixedly mounted on the lower end of the mounting block.

[0021] The beneficial effect of the above-mentioned further solution is that the installation platform can be easily moved by the casters when not in use. Attached Figure Description

[0029] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a working platform for installing anchor bolts in tunnels includes an installation platform 1, a handle 2 fixedly connected to the right side of the installation platform 1, a position adjustment component and an angle adjustment component provided at the upper end of the installation platform 1, the angle adjustment component being located on the position adjustment component, and a lifting component provided at the lower end of the installation platform 1.

[0032] Furthermore, the angle adjustment component includes a mounting plate 311. Multiple mounting plates 311 are provided on the upper end of the mounting platform 1. A mounting column 312 is rotatably connected to the rear side of the upper end of the mounting plate 311. A first connecting rod 313 is rotatably connected to the front side of the mounting column 312. A first threaded rod 316 is threadedly connected to the middle of the other end of the first connecting rod 313. A first knob 317 is fixedly connected to the front end of the first threaded rod 316. The first threaded rod 316 is rotatably connected to the mounting plate 311. The mounting plate 311 is connected to the position adjustment component. By turning the first knob 317, the first knob 317 drives the first threaded rod 316 to rotate, causing the first threaded rod 316 to drive the first connecting rod 313 to move. The first connecting rod 313 pulls the mounting column 312, causing the mounting column 312 to tilt.

[0033] The mounting plate 311 has a first groove 315 in the middle, and the other end of the first connecting rod 313 is rotatably connected to a first slider 314 that cooperates with the first groove 315. The first slider 314 is threadedly connected to the first threaded rod 316, and the first threaded rod 316 is rotatably connected to the inner wall of the first groove 315, so that the movement of the first connecting rod 313 driven by the first threaded rod 316 during rotation is more stable.

[0034] The position adjustment component includes a second slide groove 318 and a second threaded rod 319. The upper end of the mounting platform 1 is provided with a second slide groove 318, and the second threaded rod 319 is provided in the second slide groove 318. A second knob 320 is fixedly connected to the front end of the second threaded rod 319. The angle adjustment component is threadedly connected to the second threaded rod 319. By turning the second knob 320, the second knob 320 drives the second threaded rod 319 to rotate, so that the angle adjustment component slides in the second slide groove 318, thereby adjusting the position of the angle adjustment component.

[0035] The mounting post 312 has a mounting groove 321 in the middle and a threaded hole on the rear side. The rear side of the mounting post 312 is threaded with a third threaded rod 322 that mates with the threaded hole. The anchor rod is inserted into the mounting groove 321 and fastened using the third threaded rod 322, which facilitates quick installation and removal of the anchor rod.

[0036] The anchor rod is inserted into the mounting slot 321 by setting a position adjustment component and an angle adjustment component. By turning the first knob 317, the first connecting rod 313 pulls the mounting column 312, causing the mounting column 312 to tilt, thereby adjusting the installation angle of the anchor rod. By turning the second knob 320, the mounting plate 311 moves, thereby adjusting the installation position of the anchor rod. The installation position and angle of the anchor rod can be adjusted quickly, and multiple sets of anchor rods can be installed at the same time. The operation is simple, saves manpower, and is convenient for construction personnel to use.

[0037] Example 2

[0038] like Figure 1 and Figure 5 As shown, it includes a mounting platform 1, a handle 2 fixedly connected to the right side of the mounting platform 1, a position adjustment component and an angle adjustment component provided at the upper end of the mounting platform 1, the angle adjustment component being located on the position adjustment component, and a lifting component provided at the lower end of the mounting platform 1.

[0039] The lifting assembly includes support members and adjusting members respectively located at the four corners of the lower end of the mounting platform 1. The support members include a support column 411 fixedly connected to the lower end of the mounting platform 1, a rod 412 inserted into the middle of the support column 411, a slot 413 that cooperates with the rod 412 in the middle of the support column 411, a base 414 fixedly connected to the lower end of the rod 412, and the adjusting members are connected to the rod 412 to drive the rod 412 to move vertically.

[0040] The adjusting component includes a second connecting rod 415 rotatably connected to the end of the insertion rod 412, and a fourth threaded rod 418 threadedly connected to the other end of the second connecting rod 415. A third knob 419 is fixedly connected to the outside of the fourth threaded rod 418, and the fourth threaded rod 418 is rotatably connected to the lower end of the mounting platform 1.

[0041] By turning the third knob 419, the third knob 419 drives the fourth threaded rod 418 to rotate, which in turn drives the second connecting rod 415 to move. This causes the second connecting rod 415 to push the insertion rod 412 out of the slot 413, thereby adjusting the extension length of the insertion rod 412 to support the mounting platform 1. Multiple sets of insertion rods 412 are provided, and the extension length of each set can be adjusted individually. The extension length of each set of insertion rods 412 can be adjusted according to the terrain, so that the mounting platform 1 is always in a horizontal state, which facilitates the installation of anchor bolts.

[0042] The lower end of the mounting platform 1 is provided with a third slide groove 417. The end of the second connecting rod 415 is rotatably connected to a second slider 416 that cooperates with the third slide groove 417. The second slider 416 is threadedly connected to a fourth threaded rod 418. The fourth threaded rod 418 is rotatably connected to the inner wall of the third slide groove 417, so that the movement of the second connecting rod 415 driven by the fourth threaded rod 418 during rotation is more stable.

[0043] The lower end of the support column 411 is fixedly connected to the mounting block 420, and the lower end of the mounting block 420 is fixedly installed with a caster wheel 421, which allows the mounting platform to be moved easily when the mounting platform 1 is not in use.

[0044] By setting up a lifting component, the telescopic length of each set of plug rods 412 can be adjusted individually by turning the third knob 419 of different groups. The extension length of each set of plug rods 412 can be adjusted according to the terrain, so that the installation platform 1 is always in a horizontal state, which facilitates the installation of anchor rods.

[0045] Working principle: Push handle 2 to push the mounting platform 1 into the tunnel. Turn the third knob 419, which drives the fourth threaded rod 418 to rotate, causing the second slider 416 to slide in the third groove 417. This causes the second connecting rod 415 to push the insertion rod 412 out of the slot 413. Depending on the flatness of the tunnel terrain and the height of the anchor installation position, turn the third knob 419 to extend each set of insertion rods 412 by different lengths, so that the mounting platform 1 is in a horizontal state and at the same time raised, making the height of the mounting platform 1 convenient for installing the anchor. When the insertion rod 412 is extended, the caster wheel 421 is lifted off the ground, and the position of the mounting platform 1 is fixed. At this time, the preparation work is completed.

[0046] Insert the anchor rod into the mounting groove 321, and turn the third threaded rod 322 so that the third threaded rod 322 abuts against the anchor rod in the mounting groove 321 to fix the anchor rod. Turn the second knob 320, and the second knob 320 drives the second threaded rod 319 to rotate, so that the mounting plate 311 slides in the second slide groove 318. Adjust the position of the mounting plate 311 according to the installation position of the anchor rod. Turn the first knob 317, and the first knob 317 drives the first threaded rod 316 to rotate, so that the first slider 314 slides in the first slide groove 315, so that the first connecting rod 313 pulls the mounting column 312, so that the mounting column 312 tilts. Turn the first knob 317 according to the installation angle of the anchor rod to adjust the tilt angle of the mounting column 312.
