Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tunnel construction equipment, specifically relating to a tunnel arch working trolley. Background Technology
[0002] During the construction of tunnels, concrete pouring is required. When pouring concrete at the bottom of the tunnel, the simple trestle bridge and the existing self-propelled invert arch pouring trolley are usually arranged separately from the formwork device. When pouring, workers need to install the formwork device in advance and wait for the concrete to solidify before removing the formwork. This process is repeated for the next section of the tunnel.
[0003] A search revealed that CN219101356U discloses a self-propelled two-lane inverted arch pouring trolley that facilitates material feeding. The trolley includes a main body with uprights on both the front and rear sides. Movable chutes are provided on both the front and rear sides of the uprights, and sliders are installed within each chute. This application addresses the problem that some existing self-propelled two-lane inverted arch pouring trolleys require adjusting the position of the concrete mixer truck and moving the guide chute on the trolley during the pouring process, resulting in an extremely inconvenient material feeding method.
[0004] However, during use, this application is prone to problems such as concrete material adhering to the inner wall of the movable chute, which can cause the slider to be obstructed from sliding inside. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a tunnel invert arch operation trolley, which solves the problem that concrete material adhering to the inner wall of the movable chute can easily cause the slider to slide inside.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A tunnel invert work trolley, comprising:
[0008] A vertical plate, wherein a sliding groove is provided on the vertical plate, and a groove communicating with the sliding groove is provided on the top of the sliding groove, and a rack is fixedly connected in the groove;
[0009] The slider has an internal cavity with first bevel gears symmetrically arranged on both sides of the cavity. A first rotating shaft is fixedly connected to the first bevel gear and extends through the slider to the outer side of the slider end, so that the first rotating shaft is rotatably connected to the slider. A brush roller is fixedly connected to the other end of the first rotating shaft. A second bevel gear meshes between the two first bevel gears. A second rotating shaft is fixedly connected to the second bevel gear and extends through the slider to the outer side of the upper end of the slider, so that the second rotating shaft is rotatably connected to the slider. A gear is fixedly connected to the other end of the second rotating shaft, and the gear meshes with a rack.
[0010] The slider has side frames at both ends, and a scraper plate is fixedly connected to the side of the side frame away from the slider. The side frame and the slider are fixedly connected by a connecting rod.
[0011] The principles and technical effects of the above technical solution are as follows:
[0012] As the slider moves within the chute, the meshing connection between the rack and the gear causes the gear to rotate. This rotation, via the second shaft, drives the second bevel gear to rotate, which in turn drives the two first bevel gears to rotate. This rotation, via the first shaft, drives the brush roller to rotate. The brush roller cleans the loose concrete material within the chute and, in conjunction with the scraper plate, removes any adhered and hardened concrete material, reducing the obstruction caused by the concrete material as the slider moves within the chute.
[0013] In a preferred embodiment, the present invention can be further configured such that the side frame and the shovel plate are both in contact with the top, bottom and side wall of the chute.
[0014] In a preferred embodiment, the present invention can be further configured such that: a connecting ring is fixedly connected to the inner side of the side frame, the connecting ring is rotatably connected to the first rotating shaft, and the connecting rod is fixedly connected to the connecting ring.
[0015] In a preferred embodiment, the present invention can be further configured such that each end of the slider is provided with two brush rollers, and the brush rollers are disposed on both sides of the side frame.
[0016] In a preferred embodiment, the present invention may be further configured to include a main vehicle body, wherein upright plates are fixedly connected to both sides of the main vehicle body.
[0017] In a preferred embodiment, the present invention can be further configured such that: a connecting plate is detachably connected to the outer side of the slider, a column is fixedly connected to the connecting plate, and a feed groove is rotatably connected to the upper end of the column.
[0018] In a preferred embodiment, the present invention can be further configured as follows: two vertically parallel limiting plates are fixedly connected to the outer side of the slider, a first through hole is provided on the limiting plate, one end of the connecting plate is inserted between the two limiting plates, and a second through hole corresponding to the first through hole is provided on the connecting plate.
[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:
[0020] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.
[0021] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.
[0022] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.
[0023] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together as one unit.
[0024] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.
[0025] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.
[0026] The beneficial effects of this utility model are:
[0027] As the slider moves within the chute, the meshing connection between the rack and the gear causes the gear to rotate. This rotation, via the second shaft, drives the second bevel gear to rotate, which in turn drives the two first bevel gears to rotate. This rotation, via the first shaft, drives the brush roller to rotate. The brush roller cleans the loose concrete material within the chute and, in conjunction with the scraper plate, removes any adhered and hardened concrete material, reducing the obstruction caused by the concrete material as the slider moves within the chute.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0035] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0036] Based on the concept of this application, combined with Figures 1 to 5 This describes an embodiment of a tunnel invert working trolley. Specifically, the tunnel invert working trolley is constructed as a split structure, comprising components such as a vertical plate 1, a chute 2, and a slider 5. Through the cooperation of structures such as the brush roller 9 and the scraper plate 14, when the chute 5 moves within the chute 2, the meshing connection between the rack 4 and the gear 12 causes the gear 12 to rotate. This rotation, via the second rotating shaft 11, drives the second bevel gear 10 to rotate. The rotation of the second bevel gear 10, in turn, drives the two first bevel gears 7 to rotate. This rotation, via the first rotating shaft 8, drives the brush roller 9 to rotate. The brush roller 9 cleans the loose concrete material within the chute 2. Simultaneously, the scraper plate 14 removes any adhered and hardened concrete material, reducing the obstruction caused by concrete material when the slider 5 moves within the chute 2.
[0037] like Figures 1 to 5As shown, a tunnel invert arch working trolley.
[0038] A vertical plate 1 is provided with a sliding groove 2. A groove 3 communicating with the sliding groove 2 is provided at the top of the sliding groove 2. A rack 4 is fixedly connected in the groove 3.
[0039] The slider 5 has a cavity 6 inside. The cavity 6 has two symmetrically arranged first bevel gears 7. The first bevel gears 7 are fixedly connected to the first bevel gears 7. The first bevel gears 7 extend through the slider 5 to the outer side of the end of the slider 5, so that the first bevel gears 8 and the slider 5 are rotatably connected. The other end of the first bevel gears 8 is fixedly connected to a brush roller 9. The two first bevel gears 7 mesh together with a second bevel gear 10. The second bevel gear 10 is fixedly connected to a second bevel gear 11. The second bevel gear 11 extends through the slider 5 to the outer side of the upper end of the slider 5, so that the second bevel gear 11 and the slider 5 are rotatably connected. The other end of the second bevel gear 11 is fixedly connected to a gear 12, which meshes with a rack 4.
[0040] The slider 5 has side frames 13 at both ends. A scraper plate 14 is fixedly connected to the side of the side frame 13 away from the slider 5. The side frame 13 and the slider 5 are fixedly connected by a connecting rod 15.
[0041] In use, when the slider 5 moves in the groove 2, the meshing connection between the rack 4 and the gear 12 causes the gear 12 to rotate. This rotation is driven by the second shaft 11, which in turn drives the second bevel gear 10 to rotate. The rotation of the second bevel gear 10 drives the two first bevel gears 7 to rotate, which in turn drives the brush roller 9 to rotate via the first shaft 8. The brush roller 9 cleans the loose concrete material in the groove 2. At the same time, it works with the scraper plate 14 to remove the adhered and solidified concrete material, reducing the obstruction caused by the concrete material when the slider 5 moves in the groove 2.
[0042] Of course, in some other embodiments, the method of driving the second bevel gear to rotate in this application can also be configured as follows: the gear 12 in this application is replaced with a roller, the rack 4 is removed, so that the circumference of the roller is in close contact with the inner wall of the groove. In order to improve the friction between the roller and the inner wall of the groove, a rubber ring can be wrapped around the circumference of the roller. When in use, when the slider 5 moves in the groove 2, the roller rolls with the inner wall of the groove 3. The rotation of the roller drives the second bevel gear 10 to rotate through the transmission of the second rotating shaft 11. The rotation of the second bevel gear 10 drives the two first bevel gears 7 to rotate. The brush roller 9 is driven to rotate through the transmission of the first rotating shaft 8. The brush roller 9 cleans the loose concrete material in the groove 2. At the same time, it works with the scraper plate 14 to remove the adhered and solidified concrete material, reducing the obstruction caused by the concrete material when the slider 5 moves in the groove 2.
[0043] Of course, specifically in this application, when the brush roller 9 rotates, it relies on the nylon bristles arranged on its periphery to clean the inner wall of the chute 2. The nylon bristles are flexible, so during installation, the nylon bristles should be made to contact the inner wall of the chute 2 as much as possible to improve the cleaning effect. At the same time, through the configuration of the transmission method, when the brush roller 9 at the front end of the slider 5 moves, the bottom of the brush roller 9 rotates towards the outside of the chute 2, sweeping the concrete material inside the chute 2 out of the chute 2.
[0044] For concrete material that has solidified and adhered to the inner wall of the chute 2, in order to improve the removal effect, the side frame 13 and the scraper plate 14 should be fitted to the top, bottom and side wall of the chute 2 to ensure the removal effect.
[0045] Since the side frame 13 and the slider 5 are fixedly connected by the connecting rod 15, when the shovel plate 14 is removing fixed concrete material, the side frame 13 and the shovel plate 14 may tilt over a long period of use. A connecting ring 16 is fixedly connected to the inner side of the side frame 13. The connecting ring 16 is rotatably connected to the first rotating shaft 8. The connecting rod 15 is fixedly connected to the connecting ring 16. At this time, with the cooperation of the first rotating shaft 8 and the connecting ring 16, the side frame 13 and the shovel plate 14 can play a certain anti-tilting effect.
[0046] After the scraper plate 14 removes the fixed concrete material, the concrete material will still accumulate at the end of the slider 5. In order to further ensure the cleaning effect, each end of the slider 5 is equipped with two brush rollers 9. The brush rollers 9 are located on both sides of the side frame 13. When the slider 5 moves in the chute 2, the brush roller 9 at the front end sweeps the loose concrete material in the chute 2. After the scraper plate 14 removes the adhered and solidified concrete material, the brush rollers 9 between the scraper plate 14 and the slider 5 further clean the removed concrete material.
[0047] In one embodiment of this utility model, a main vehicle body 17 is further included, with upright plates 1 fixedly connected to both sides of the main vehicle body 17. Each upright plate 1 has a sliding groove 2 on its outer side, and a slider 5 is slidably connected within each groove 2. A connecting plate 18 is detachably connected to the outer side of the slider 5, and a column 19 is fixedly connected to the connecting plate 18. A material feeding chute 20 is rotatably connected to the upper end of the column 19. Concrete pouring requires the use of a trolley. During use, the concrete mixer truck is driven onto the main vehicle body 17, and the material feeding chute 20 is moved to the desired position by sliding the slider 5 within the movable groove 2. The angle of the material feeding chute 8 is adjusted. The discharge port of the concrete mixer truck is located on the material feeding chute 8. During concrete pouring, concrete flows into the pouring position through the guide of the material feeding chute 8. When the position of the concrete mixer truck needs to be adjusted according to the pouring position, the movement of the concrete mixer truck can be directly controlled.
[0048] Specifically, two vertically parallel limiting plates 21 are fixedly connected to the outer side of the slider 5. The limiting plates 21 have a first through hole. One end of the connecting plate 18 is inserted between the two limiting plates 21. The connecting plate 18 has a second through hole corresponding to the first through hole. After the bolt passes through the first through hole and the second through hole, it is tightened with a nut to realize the detachable installation between the slider 5 and the connecting plate 18.
