Description
Technical Field
[0001] This utility model relates to the field of tunnel construction, specifically to a mobile debris-blocking pier. Background Technology
[0002] During the construction of the main tunnel, inclined shafts are built. The inclined shafts are connected to the main tunnel and are sloping. By building inclined shafts, multiple purposes such as ventilation, drainage, and material transportation can be achieved.
[0003] Currently, there are two types of methods for excavating inclined shafts: forward excavation and reverse excavation. Forward excavation means digging from the outside of the mountain into the main tunnel to build an inclined shaft; reverse excavation means digging from the inside of the main tunnel into the outside of the mountain to build an inclined shaft.
[0004] Currently, during the reverse excavation of inclined shafts, a large number of rocks will roll down the slope during blasting, which may impact construction workers and pose a great safety threat to them. Utility Model Content
[0005] The present invention aims to provide a mobile debris-blocking pier to solve the problem of a large number of rocks rolling down the slope during the blasting of inclined shafts, posing a safety threat to construction workers.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mobile slag-blocking pier, comprising a vehicle body, wheels installed at the bottom of the vehicle body, and slag-blocking units installed on the vehicle body, the slag-blocking units comprising pier bodies;
[0007] The vehicle body is equipped with a positioning unit, which includes a vertical rod for insertion into the slope and a drive unit for driving the vertical rod to move vertically. The drive unit is mounted on the vehicle body.
[0008] The principle and advantages of this application are as follows: The vehicle body in this application is equipped with wheels at the bottom, allowing the entire debris-blocking pier to move on the slope. During the inclined shaft construction process, the debris-blocking pier can be moved according to different construction stages, positioning itself at different locations on the slope. After the debris-blocking pier is moved to the corresponding position on the slope, the drive mechanism is activated, causing the vertical insertion rod to move downwards and insert into a hole on the slope. This achieves the positioning and fixation of the debris-blocking pier, ensuring it remains stationary and does not move on the slope. During blasting operations in the inclined shaft, construction personnel standing behind the debris-blocking pier can be protected by its debris-blocking unit, preventing large amounts of rocks from rolling down the slope and reducing injury to personnel, thus improving construction safety.
[0009] Preferably, as an improvement, the vehicle body includes a floor plate and a roof plate, with the debris-blocking unit located between the floor plate and the roof plate. Thus, the debris-blocking unit is situated between the roof plate and the floor plate, with most of the space between them occupied by the debris-blocking unit, thereby effectively blocking rolling stones.
[0010] Preferably, as an improvement, the slag-blocking unit also includes a slag-blocking plate, which is fixedly located at the front of the vehicle body, and the pier is located behind the slag-blocking plate, abutting against it. Thus, with the slag-blocking plate at the front of the vehicle body, it blocks falling stones. The pier, located behind the slag-blocking plate and abutting against it, has a relatively large volume and weight, providing support for the slag-blocking plate. This improves the slag-blocking plate's resistance to stone impact, reduces deformation after impact, and ensures its service life.
[0011] Preferably, as an improvement, the pier is made of reinforced concrete. Therefore, the pier, being made of reinforced concrete, is low in cost and has high structural strength, effectively resisting the impact of rolling stones.
[0012] Preferably, as an improvement, the number of vertical insertion rods is multiple; the positioning unit also includes a movable plate, which is connected to the multiple vertical insertion rods, and the drive unit is connected to the movable plate.
[0013] Therefore, multiple vertical rods are used, which are inserted into the holes on the slope. Compared with a single vertical rod, this improves the stability of the retaining pier. By using a movable plate to connect the multiple vertical rods, the driving component can simultaneously move the multiple vertical rods by driving the movable plate.
[0014] Preferably, as an improvement, the drive unit is mounted on the roof panel, the vertical insert can pass through the pier and the floor panel, the vertical insert and the pier are in sliding engagement, the vertical insert and the floor panel are in sliding engagement, and the vertical insert can extend downward from the floor panel.
[0015] Therefore, by having the vertical rods pass through the pier body, compared to placing them on the outside of the pier body, the space occupied by the vertical rods and the pier body can be reduced, making the structure of the vertical rods and the pier body more compact. At the same time, the vertical rods passing through the pier body also have an auxiliary role in fixing the pier body laterally, making the pier body more firmly and stably fixed to the vehicle body.
[0016] Preferably, as an improvement, the positioning unit also includes a sleeve, which is fixedly located inside the pier body; the vertical rod is inserted into the sleeve. Thus, the sleeve isolates the pier body from the vertical rod, preventing direct contact between the vertical rod and the pier body concrete during vertical sliding, allowing for smoother sliding. During pier construction, the sleeve is first fixed to the vehicle body, and then concrete is poured to form the pier body. After the concrete is poured, the sleeve is then fixed inside the pier body.
[0017] Preferably, as an improvement, multiple fixing rods are fixedly connected between the roof panel and the floor panel, with the fixing rods surrounding the left, right, and rear sides of the pier. Thus, the multiple fixing rods serve to limit the movement of the pier.
[0018] Preferably, as an improvement, the number of driving components is two, and the two driving components are respectively connected to both ends of the moving plate.
[0019] Preferably, as an improvement, the side of the vehicle floor is fixedly provided with a rotating part and a rotating shaft for inserting into the slope, and the rotating shaft and the rotating part are rotatably engaged.
[0020] In actual use, a rock-blocking pier is set on each side of the slope to block the rolling stones, but this affects the movement of vehicles and machinery. With this solution, when vehicles and machinery move, the rock-blocking piers rotate around their pivot axis, causing them to rotate towards the side of the inclined shaft. This creates space between the two piers, allowing vehicles and machinery to pass through. Attached Figure Description

[0028] Example 1
[0029] The basics are as follows: Figures 1-4 As shown: This embodiment discloses a mobile slag-blocking pier, including a vehicle body, a slag-blocking unit, and a positioning unit.
[0030] The vehicle body in this embodiment includes a roof panel 2, a floor panel 3, and multiple fixing rods 6. All components—roof panel 2, floor panel 3, and fixing rods 6—are made of steel. The roof panel 2 is located above the floor panel 3. The fixing rods 6 are vertically arranged and fixed (e.g., by welding or bolting) between the roof panel 2 and the floor panel 3. In this embodiment, the fixing rods 6 are located on the left, right, and rear sides of the vehicle body. The floor panel 3 is equipped with multiple wheels 14, which can be omnidirectional wheels. By installing multiple wheels 14 on the bottom of the floor panel 3, the vehicle body can move on the ground.
[0031] A slag-blocking unit is installed on the vehicle body. In this embodiment, the slag-blocking unit includes a pier 5 and a slag-blocking plate 4. The slag-blocking plate 4 is fixedly located on the front side of the vehicle body. Specifically, in this embodiment, the slag-blocking plate 4 is a steel plate, which is vertically arranged. The top and bottom of the slag-blocking plate 4 are welded or fixed to the roof plate 2 and the floor plate 3, respectively. In this embodiment, the pier 5 is located behind the slag-blocking plate 4, and the pier 5 and the slag-blocking plate 4 abut against each other. Multiple fixing rods 6 surround the pier 5 from the left, right, and rear sides.
[0032] In this embodiment, pier 5 is specifically a reinforced concrete pier, combined with... Figure 3 As shown, when installing the pier 5, the steel cage 13 is first installed on the vehicle body, for example, by welding, and then concrete is poured. The concrete and the steel cage 13 are combined together, and the pier 5 is formed after the concrete solidifies.
[0033] The positioning unit in this embodiment includes vertical insertion rods 9 for insertion into the ramp 1 and driving components 7 for vertical movement of the vertical insertion rods 9. The driving components 7 are mounted on the vehicle body. Specifically, there are two driving components 7 in this embodiment, each mounted on the roof panel 2. The driving components 7 can be cylinders or hydraulic cylinders, with the piston rods of the driving components 7 pointing upwards. A movable plate 8 connects the two driving components 7, and the movable plate 8 is connected to the piston rods. The connection can be fixed with bolts. There are multiple vertical insertion rods 9, and in this embodiment, there are two. The tops of the two vertical insertion rods 9 are welded to the bottom of the movable plate 8. Of course, the height of the top of the slag-blocking plate 4 can extend upwards and be higher than the height of the top of the driving components 7, thereby shielding the driving components 7 and preventing them from being splashed by gravel.
[0034] The vertical insert rod 9 and the pier body 5 slide together. Specifically, the pier body 5 has two sleeves 12 inside. The top ends of the two sleeves 12 are welded to the roof plate 2, and the bottom ends of the two sleeves 12 are welded to the floor plate 3. The floor plate 3 has through holes communicating with the sleeves 12. The vertical insert rod 9 passes through the sleeves 12 and can slide vertically within the sleeves 12. Figure 4 As shown, the vertical insert 9 can pass downward through the through hole on the vehicle floor 3.
[0035] The specific assembly method of the movable debris-blocking pier in this embodiment is as follows: First, fix the vehicle floor plate 3, vehicle roof plate 2, and debris-blocking plate 4 together. Then, fix the sleeve 12 and the reinforcing cage 13 between the vehicle roof plate 2 and the vehicle floor plate 3. Then, pour concrete, and the concrete and the reinforcing cage 13 are combined together. The sleeve 12 and the concrete are also combined together. Then, fix the fixing rod 6 between the vehicle roof plate 2 and the vehicle floor plate 3. Finally, install the driving component 7 on the vehicle roof plate 2, insert the vertical insertion rod 9 into the sleeve 12, and fix the movable plate 8 to the vertical insertion rod 9 and the piston rod of the driving component 7 respectively.
[0036] The specific implementation process is as follows: In this embodiment, the bottom of the vehicle base plate 3 is equipped with wheels 14, and the entire slag-blocking pier can move on the slope 1. Thus, during the construction of the inclined shaft, the slag-blocking pier can be moved according to different construction progresses, and the slag-blocking pier can be moved to different parts of the slope 1.
[0037] Before fixing the movable slag barrier on slope 1, drill two holes at the corresponding positions on slope 1. Then, move the slag barrier to the corresponding position on slope 1, and start the drive unit 7. The drive unit 7 drives the moving plate 8 downward, and the moving plate 8 drives the two vertical rods 9 downward. Figure 4As shown, the vertical insertion rod 9 is inserted into the insertion hole on the slope 1, thereby achieving the positioning and fixation of the debris-blocking pier. The debris-blocking pier will not move on the slope 1 and will remain stable and stationary. This allows construction personnel to stand at a considerable distance behind the debris-blocking pier during blasting operations in the inclined shaft. The debris-blocking plate 4 of the pier can block the rolling stones, preventing a large number of stones from rolling down the slope 1, thus reducing injury to construction personnel and improving construction safety. The depth of the insertion hole is set according to the actual situation; for example, the depth of the insertion hole should not be less than 20cm to ensure the stability of the debris-blocking pier fixed on the slope 1.
[0038] Combination Figure 2 As shown, in order to ensure the interception effect of the movable debris barriers on the rolling stones, two debris barriers can be set on the slope 1 in specific implementation. The two debris barriers are close to the left and right sides of the slope 1 respectively. In this way, the two debris barriers can basically cover the slope 1 in the width direction, thereby effectively intercepting the rolling stones rolling on the slope 1.
[0039] When it is necessary to change the position of the slag barrier, start the drive unit 7. The drive unit 7 drives the moving plate 8 to move upward. The moving plate 8 drives the two vertical rods 9 to move upward. The two vertical rods 9 slide upward in the sleeve 12. The bottom of the two vertical rods 9 comes out from the insertion hole. The slag barrier is released from fixation. Then, the slag barrier can be moved on the slope 1 by pushing manually or using a tractor.
[0040] Example 2
[0041] Combination Figure 5 As shown, this embodiment further defines the features of Embodiment 1. In this embodiment, the side of the vehicle floor 3 is fixedly (integrated or welded) with a rotating part 10 (also made of steel plate) and a rotating shaft 11 for insertion onto the ramp 1. The rotating part 10 has a shaft hole, into which the rotating shaft 11 is inserted, and the rotating shaft 11 and the rotating part 10 are rotatably coupled. The ramp 1 has a hole for inserting the rotating shaft 11. In this embodiment, the distance between the left and right sides of the vehicle body is greater than the distance between the front and rear sides of the vehicle body.
[0042] In actual use, a slag-blocking block will be set on each side of the slope 1 to block the rolling stones. In order to ensure the slag-blocking effect, the distance between the two slag-blocking blocks is small in the specific implementation (the distance between the right end of the left slag-blocking block and the left end of the right slag-blocking block is small), or the left slag-blocking block and the right slag-blocking block overlap to a certain extent. However, this will affect the movement and passage of vehicles and mechanical equipment between the two slag-blocking blocks.
[0043] In the embodiment, when the vehicle and mechanical equipment move, the slag-blocking block is first rotated, that is, the vertical insertion rod 9 is moved upward and pulled out of the insertion hole. Then the slag-blocking block is pushed, and the slag-blocking block rotates around the rotating shaft 11, so that the slag-blocking block rotates towards the side of the inclined shaft. In this way, space is made between the two slag-blocking blocks so that the vehicle and mechanical equipment can pass through.
