Description

Technical Field

[0001] The utility model relates to the technical field of tunnel roof lifting construction, and particularly relates to a slag discharging device for tunnel roof lifting construction. Background Technique

[0002] In tunnel construction, roof lifting construction is a key step, which involves the excavation and cleaning of the tunnel roof. During the roof lifting process, a large amount of slag blocks will be generated. If these slag blocks are not cleaned and transported in time, it will seriously hinder the construction progress and may even lead to safety accidents. Therefore, in tunnel roof lifting construction, a slag discharging device is needed to transport the generated slag blocks out of the construction area to ensure the smooth progress of the construction.

[0003] In the prior art, there is certain research on the slag discharging device for tunnel roof lifting construction. Refer to the patent document with the application number 201910871480.1, which discloses a slag discharging device and method for a small-section long steep-slope tunnel in a plateau area, including: a mucking loader, a towing rope, a transport vehicle body, and a winch. During the specific construction process, the winch operates to wind up the towing rope, and the towing rope pulls the slag transport truck to move under the top of the conveyor track of the mucking loader; the mucking loader shovels the earth and stone generated by blasting onto the receiving shovel, and the conveyor track transports the earth and stone to the top of the conveyor track, and the earth and stone automatically fall into the slag transport truck until the slag transport truck is full; the winch operates to evenly unwind the towing rope, and the slag transport truck moves uniformly towards the tunnel entrance under the action of its own gravity and the gravity of the earth and stone. When the slag transport truck moves outside the tunnel, drive the slag transport truck to a designated position and unload the earth and stone to realize the transportation of the earth and stone.

[0004] It can be seen from this that through the coordinated use of a winch, a mucking loader, and a conveyor track, the transportation of earth and stone is realized. However, during the actual roof lifting construction process, the mucking loader needs to first shovel the earth and stone generated by blasting onto the receiving shovel, then the conveyor track transports the earth and stone to the top, and finally the earth and stone fall from the top of the conveyor track into the slag transport truck to realize the unloading of the earth and stone. The whole earth and stone unloading process is cumbersome and time-consuming, resulting in low slag discharging efficiency and affecting the overall construction progress of the tunnel roof lifting construction.

The front wheels at the bottom of the slag discharging hopper are placed on the chute and gradually rise as the slag discharging hopper moves. When the slag discharging hopper is transported to the end of the chute, due to the loss of support of the front wheels, the slag discharging hopper automatically turns over, and then the slag blocks are dumped into the discharging area; the provided slag discharging hopper, through the setting of automatic turning over, greatly simplifies the slag discharging process, improves the slag discharging efficiency, and further improves the overall construction progress of the tunnel roof lifting construction.

Detailed implementation mode

[0024] The technical solution of the present utility model will be further explained below in conjunction with the drawings and embodiments, but the present utility model is not limited to the following described implementation modes.

[0025] Refer to Figure 1 and Figure 2 In the present utility model, during the construction of extra-long tunnels, in order to improve the construction progress, auxiliary tunnels are usually constructed on the side of the mountain to open up a heading face for tunneling. When the auxiliary tunnel is constructed to the position intersecting with the main tunnel, roof bolting construction needs to be carried out at the roof bolting construction face 100 to break through and open up the heading face of the main tunnel. In roof bolting construction, static blasting, as an advanced blasting method, has the advantage that it can utilize the characteristic that the tensile strength of rock or concrete is relatively low to expand and break the surrounding rock around the hole wall through a hydraulic mechanical device without generating vibration, impact and noise. The present utility model is suitable for the transportation of slag blocks generated by static blasting.

[0026] Refer to Figure 1 and Figure 2 A slag discharging device for tunnel roof bolting construction includes: a slag discharging hopper 1, a guiding chute 4 and a winch traction assembly 5. The slag discharging hopper 1 is used to receive the slag blocks generated during the tunnel roof bolting construction, and the bottom of the slag discharging hopper 1 is provided with a front wheel 2 and a rear wheel 3 for the movement of the slag discharging hopper 1; the guiding chute 4 is used to guide the movement of the slag discharging hopper 1, the rear wheel 3 of the slag discharging hopper 1 is engaged in the guiding chute 4, and the front wheel 2 of the slag discharging hopper 1 is placed on the guiding chute 4; the winch traction assembly 5 is connected to the slag discharging hopper 1 and is placed at the discharging end of the guiding chute 4 for pulling the slag discharging hopper 1 to move along the extending direction of the guiding chute 4.

[0027] Specifically, the guiding chute 4 is installed on the traveling device, and by adjusting the position of the traveling device, the position of the slag discharging hopper 1 is further adjusted so that the slag discharging hopper 1 is located directly below the slag blocks. In the present utility model, the guiding chute 4 is connected to the traveling device through an inverted "U" - shaped mounting seat. A slag discharging vehicle 101 is parked below the discharging end of the guiding chute 4, and the slag discharging vehicle 101 transports the slag blocks out of the construction tunnel.

[0028] In the present utility model, after the slag discharging hopper 1 receives slag blocks, it is stably moved along the guiding chute 4 under the traction of the hoisting traction assembly 5. The rear wheels 3 at the bottom of the slag discharging hopper 1 are engaged in the guiding chute 4, which is convenient for providing stable support and guidance. The front wheels 2 at the bottom of the slag discharging hopper 1 are placed on the guiding chute 4 and gradually rise as the slag discharging hopper 1 moves. When the slag discharging hopper 1 is transported to the end of the guiding chute 4, due to the loss of support of the front wheels 2, the slag discharging hopper 1 automatically turns over, and then the slag blocks are dumped onto the slag discharging vehicle 101. The provided slag discharging hopper 1 greatly simplifies the slag discharging process and improves the slag discharging efficiency through the automatic turning-over setting, thereby improving the overall construction progress of the tunnel roof lifting construction.

[0029] Refer to Figure 1 and Figure 2 , the front wheels 2 and the rear wheels 3 are respectively connected to the slag discharging hopper 1 through a set of connecting components 9. The connecting component 9 includes a connecting rod 91 and a connecting sleeve 92. The connecting sleeve 92 is connected to the slag discharging hopper 1; the connecting rod 91 is nested in the connecting sleeve 92, and both ends of the connecting rod 91 respectively extend out of both ends of the connecting sleeve 92.

[0034] Specifically, during the slag discharging process, the slag blocks are collected into the slag discharging hopper 1, and then are moved along the guiding chute 4 to the discharging position by the traction of the hoisting and traction assembly 5; when the front wheels 2 of the slag discharging hopper 1 lose support and automatically turn over, and the slag blocks are dumped into the discharging area, due to the inclined setting of the guiding chute 4, the slag discharging hopper 1 returns to the initial position along the guiding chute 4 under the action of gravity, and is ready for the next slag discharging operation.

[0035] In this embodiment, the guiding chute 4 is inclined. After the slag discharging hopper 1 discharges the slag, the operator does not need to manually pull the slag discharging hopper 1 back to the initial position, making the slag discharging process more automated and smooth, saving labor and time costs, and improving the slag discharging efficiency.

[0038] In this embodiment, the provided limiting plate 6 blocks the slag discharging hopper 1 when the slag discharging hopper 1 returns to the initial position along the guiding chute 4 under the action of gravity, avoiding the slag discharging hopper 1 from sliding out of the guiding chute 4 due to its own weight, and ensuring the safety and continuity of the slag discharging operation.

[0039] Embodiment 3:

[0040] Referring to Figure 1 and Figure 2 , for the slag discharging device for tunnel roof lifting construction in this embodiment, on the basis of Embodiment 2, the included angle between the plane where the limiting plate 6 is located and the plane where the guiding chute 4 is located is not greater than 90°.

[0041] In this embodiment, the included angle between the plane where the limiting plate 6 is located and the plane where the guiding chute 4 is located is not greater than 90°. While ensuring that the limiting plate 6 can effectively block the slag discharging hopper 1 from sliding out of the guiding chute 4, the impact force of the limiting plate 6 on the slag discharging hopper 1 is reduced, thereby protecting the integrity of the slag discharging hopper 1 and the guiding chute 4.

[0042] Embodiment 4:

[0044] In this embodiment, the engaging groove 7 is provided. When it is necessary to replace or repair the limiting plate 6, the operator only needs to take it out of the engaging groove 7 to complete the corresponding operation, which improves the maintenance convenience of the mucking device for tunnel roof bolting construction.

[0045] Embodiment 5:

[0046] Referring to Figure 1 and Figure 2 , in the mucking device for tunnel roof bolting construction of this embodiment, the winch traction assembly 5 further includes a fixing plate 53; the fixing plate 53 is connected to the driving motor 511, and the fixing plate 53 is installed on the side wall of the guiding chute 4.

[0047] In this embodiment, the provided fixing plate 53 ensures that the driving motor 511 is stably installed on the guiding chute 4, avoiding loosening of the driving motor 511 due to vibration or pulling force during work, and thus ensuring the stability and safety of the mucking hopper 1 during the moving process.

[0048] Embodiment 6:

[0049] Referring to Figure 1 and Figure 2 , in the mucking device for tunnel roof bolting construction of this embodiment, a pull ring 8 is provided at one end of the mucking hopper 1 close to the winch traction assembly 5.

At the same time, the provided pull ring 8 facilitates the operator to manually intervene or adjust the position of the mucking hopper 1.

[0051] The working principle of the mucking device for tunnel roof bolting construction of the present utility model is as follows: First, the mucking hopper 1 receives the slag blocks generated by static blasting at the tunnel roof bolting construction site; subsequently, the driving motor 511 is started, and the driving motor 511 drives the pull rod 512 to rotate clockwise, and the traction rope 513 on the pull rod 512 is wound accordingly, thereby realizing the traction of the mucking hopper 1; under the pulling force of the traction rope 513, the mucking hopper 1 stably moves along the extension direction of the guiding chute 4; during the moving process, the rear wheels 3 at the bottom of the mucking hopper 1 are engaged in the guiding chute 4, and the front wheels 2 are placed on the guiding chute 4 and gradually rise as they move; when the mucking hopper 1 is pulled to the end of the guiding chute 4, the front wheels 2 lose support, and the mucking hopper 1 automatically flips due to gravity, pouring the slag blocks onto the mucking vehicle 101 to complete a mucking cycle; adjust the driving motor 511 to reverse, the driving motor 511 drives the pull rod 512 to rotate counterclockwise, and the traction rope 513 on the pull rod 512 is unwound accordingly, thereby realizing the release of the mucking hopper 1, and the mucking hopper 1 returns to the starting position along the guiding chute 4 under the action of gravity, preparing for the next mucking operation.

[0052] The above are all preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby.
