Description

Technical Field

[0001] This invention relates to the field of transportation equipment for tunnel crushing, specifically a transportation device for tunnel crushing. Background Technology

[0002] In modern tunnel engineering construction, with the continuous advancement of infrastructure construction, various tunnel projects are increasing, covering different fields such as railway tunnels, highway tunnels, and municipal tunnels. A large amount of crushed material is generated during the tunnel excavation process. After being mined and crushed, this material needs to be transported to the outside of the tunnel by transportation equipment.

[0003] Existing transport equipment used for tunnel crushing is not very stable during use and lacks protective measures, which can easily lead to the falling of crushed stone during transportation. At the same time, when loading a large amount of crushed stone, the transport equipment is prone to deformation, which reduces the safety of the transport equipment for crushed stone transportation.

[0004] According to announcement number CN217415863U, a tunnel safety construction transportation device relates to the field of tunnel construction technology. It includes a trolley, a base fixedly mounted on the upper surface of the trolley, a side plate fixedly mounted on the upper surface of the base, a placement plate mounted on one side wall of the side plate, and a groove formed on the upper surface of the base. A threaded rod is rotatably connected to the inner wall of the groove, penetrating the inner wall of the groove and extending to the outside of the base. This utility model, by setting up a trolley, base, side plate, placement plate, groove, threaded rod, handle, limit rod, movable plate, movable block, frame, and slider, realizes the function of transporting materials. In actual use, the size and shape of the box can be changed so that the materials can be completely placed inside the box during transportation, preventing materials from falling off the device, avoiding accidents, improving the work efficiency of workers, and enhancing the practicality of the transportation device.

[0005] As described above, the transportation device used in tunnels is a trolley. The size of the trolley's compartment is changed, but the stability of the trolley compartment is not high during the adjustment process, and there is a lack of protective measures, which can easily cause the crushed stone to fall during transportation. At the same time, when loading a large amount of crushed stone, the transportation device is prone to deformation, which reduces the safety of the transportation device for crushed stone transportation. In order to solve the above-mentioned problems, an improved transportation device for tunnel crushing is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a transport device for tunnel crushing. Through the cooperation of a protective mechanism and reinforcing ribs, an L-shaped reinforcing rod is installed on the reinforcing rib via a connecting seat and fastening bolts. Its bend fits the corner of the transport vehicle body, which can effectively enhance the structural strength of the transport vehicle body, prevent deformation caused by loading a large amount of gravel, and ensure the overall stability of the transport device. The protective railings inside the carriage, together with the protective cover, can prevent gravel from falling during transportation and reduce safety hazards, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a transportation device for tunnel crushing, comprising a transport vehicle body, four reinforcing ribs fixedly connected around the perimeter of the transport vehicle body, the reinforcing ribs being symmetrical in pairs, a protective mechanism to prevent deformation of the transport vehicle body being installed on the reinforcing ribs, and anti-collision components provided on opposite sides of the transport vehicle body.

Fastening bolts that mate with the threaded holes are inserted into the inner cavity of the through holes. The reinforcing rod is L-shaped, and the bent part of the reinforcing rod is in contact with the corner of the transport vehicle body. The main body of the transport vehicle includes a movable seat and a carriage. The carriage is installed on the movable seat. Four reinforcing ribs are respectively arranged around the outside of the carriage. The inner sidewall of the reinforcing rib is attached to the outer sidewall of the carriage. The inner cavity of the carriage is provided with a guardrail. Two sides of the guardrail are provided with drive components, and the other two sides of the guardrail are provided with limit components. The drive assembly includes an electric push rod, which is mounted on top of two symmetrical reinforcing ribs. The piston rod of the electric push rod is fixedly connected to a first connecting block, one side of which is fixed to the outside of the guardrail. The limiting component includes a limiting rod, the lower end of which is fixed to the top of two other reinforcing ribs. A second connecting block is fixedly connected to the outer side of the guardrail at a position corresponding to the limiting rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a transport device for tunnel crushing. Through the cooperation of a protective mechanism and reinforcing ribs, an L-shaped reinforcing rod is installed on the reinforcing rib via a connecting seat and fastening bolts. Its bend fits the corner of the transport vehicle body, which can effectively enhance the structural strength of the transport vehicle body, prevent deformation caused by loading a large amount of gravel, and ensure the overall stability of the transport device.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This invention provides, for example Figures 1-5 The illustrated transport device for tunnel crushing includes a transport vehicle body 1. Four reinforcing ribs 2 are fixedly connected around the perimeter of the transport vehicle body 1. The reinforcing ribs 2 are symmetrically arranged in pairs. Protective mechanisms 3 are installed on the reinforcing ribs 2 to prevent deformation of the transport vehicle body 1. Anti-collision components 4 are provided on opposite sides of the transport vehicle body 1. The reinforcing ribs 2 enhance the overall structural strength of the transport vehicle body 1. The protective mechanisms 3, in conjunction with the reinforcing ribs 2, disperse and bear the pressure from the transported materials, preventing the transport vehicle body 1 from deforming due to excessive pressure. When the transport vehicle body 1 is impacted, the anti-collision components 4 buffer and disperse the impact force through their own structure, improving the safety and stability of the transport vehicle body 1 during transportation and reducing the risk of equipment damage.

[0018] The protective mechanism 3 includes a reinforcing rod 31, with connecting seats 32 fixedly connected to both ends of the reinforcing rod 31. Through holes 33 are provided at symmetrical positions on the connecting seats 32. Threaded holes 34 are provided at the contact points between the reinforcing rib 2 and the connecting seats 32. Fastening bolts 35 that mate with the threaded holes 34 are inserted into the inner cavity of the through holes 33. The reinforcing rod 31 is L-shaped, and the bent part of the reinforcing rod 31 is fitted with the corner of the transport vehicle body 1. Through the cooperation of the reinforcing rod 31, connecting seats 32, through holes 33, threaded holes 34, and fastening bolts 35, the structural strength of the corner of the transport vehicle body 1's compartment 12 is enhanced, effectively preventing corner deformation caused by heavy loading or transport bumps, extending the service life of the transport vehicle body 1, ensuring the integrity of the compartment 12 during transportation, and reducing problems such as material leakage.

[0019] The main body 1 of the transport vehicle includes a movable seat 11 and a carriage 12. The carriage 12 is mounted on the movable seat 11. Four reinforcing ribs 2 are respectively arranged around the outer perimeter of the carriage 12. The inner sidewall of the reinforcing rod 31 is attached to the outer sidewall of the carriage 12. The inner cavity of the carriage 12 is provided with a guardrail 13. Two sides of the guardrail 13 are provided with drive components 14, and the other two sides of the guardrail 13 are provided with limit components 15. First, the movable seat 11 provides mobile support for the carriage 12. The carriage 12 is used to load materials. The reinforcing ribs 2 are distributed around the carriage 12. The reinforcing rod 31 is attached to the outer sidewall of the carriage 12 for further reinforcement. The guardrail 13 works by relying on the drive components 14 and the limit components 15 to realize the lifting and lowering of the guardrail 13, which facilitates the loading and unloading of materials and prevents materials from falling, ensuring the safety of the construction environment. Moreover, the guardrail 13 can be lifted and lowered, which improves the convenience and efficiency of loading and unloading materials.

[0020] The drive assembly 14 includes an electric push rod 141, which is installed on the top of two symmetrical reinforcing ribs 2. The piston rod of the electric push rod 141 is fixedly connected to a first connecting block 142. One side of the first connecting block 142 is fixed to the outside of the guardrail 13. The electric push rod 141 provides driving force to drive the first connecting block 142 connected to it to move, thereby pushing the guardrail 13 to rise or fall, and realizing the adjustment of the height of the guardrail 13.

[0021] The limiting component 15 includes a limiting rod 151. The lower end of the limiting rod 151 is fixed to the top of two other reinforcing ribs 2. A second connecting block 152 is fixedly connected to the outer side of the guardrail 13 at a position corresponding to the limiting rod 151. A sliding sleeve 153 that works with the limiting rod 151 is embedded on the second connecting block 152. When the electric push rod 141 pushes the guardrail 13 up and down, the sliding sleeve 153 slides on the limiting rod 151, restricting the movement trajectory of the guardrail 13 so that it can only move up and down along the direction of the limiting rod 151. This ensures the stability and accuracy of the guardrail 13 during the lifting process, prevents the guardrail 13 from shaking or deviating, and ensures the stability of the guardrail 13 during use.

[0022] A protective cover 5 is hinged to the top of the guardrail 13 at a symmetrical position. The protective cover 5 has through slots on both sides facing each other. The protective cover 5 is hinged to the guardrail 13 and can be opened or closed by rotating around the hinge axis. The protective cover 5 effectively prevents materials from falling out of the carriage 12 during transportation, ensuring transportation safety.

[0023] The anti-collision component 4 includes a first spring 41, one end of which is fixed to the movable seat 11, and the other end of which is fixedly connected to an anti-collision plate 42. The outer side of the anti-collision plate 42 is arc-shaped. Through the cooperation of the first spring 41 and the anti-collision plate 42, the anti-collision plate 42 first contacts the obstacle. The external force squeezes the anti-collision plate 42, causing the first spring 41 to compress and deform. During the deformation process, the first spring 41 absorbs the collision energy, thus reducing the damage to the main body 1 of the transport vehicle and reducing the degree of damage to the main body 1 of the transport vehicle in the event of a collision, thereby protecting the materials and equipment inside the main body 1 of the transport vehicle.

[0024] The surface of the limiting rod 151 is fitted with a second spring 6. One end of the second spring 6 is fixed to the reinforcing rib 2, and the other end of the second spring 6 is fixed to the lower surface of the second connecting block 152. The designed second spring 6 can provide a buffering effect for the guardrail 13 during descent, avoiding collision between the second connecting block 152 and the carriage 12.

[0025] One end of the movable seat 11 is fixedly connected to a pull rod 7, and one end of the pull rod 7 is fixedly connected to a fixing ring 8. Through the cooperation of the pull rod 7 and the fixing ring 8, the main body of the transport vehicle 1 can be easily connected to other equipment, thereby enabling the main body of the transport vehicle 1 to move within the tunnel.

[0026] Reflective stickers 9 are affixed to the four sides of the carriage 12. The reflective stickers 9 are distributed at the upper and lower ends of the carriage 12. By attaching reflective stickers 9 to the carriage 12, the warning effect for workers is improved, and collisions between workers and the main body of the transport vehicle 1 are avoided, thereby improving the personal safety of workers.

[0027] In practical use, the crushed material to be transported is first loaded into the carriage 12. At this time, the reinforcing ribs 2 and the reinforcing rods 31 of the protective mechanism 3 enhance the structural strength of the carriage 12, which can withstand the weight of the material and prevent the carriage 12 from deforming. During the loading and unloading of crushed stone, the electric push rod 141 is activated according to the loading and unloading situation of the truck bed 12. Its piston rod extends and retracts to drive the first connecting block 142, thereby pushing the guardrail 13 to rise or fall. The limit rod 151 of the limit component 15 cooperates with the sliding sleeve 153 to ensure the stable lifting and lowering of the guardrail 13 and avoid swaying and deviation. When the guardrail 13 is lowered, it is convenient to load and unload materials. When it is raised, it can prevent materials from falling and ensure the safety of the construction environment. When a collision occurs during the transport of the main body 1 of the transport vehicle, the anti-collision component 4 comes into play. The arc-shaped anti-collision plate 42 contacts the obstacle first, and the impact force compresses the first spring 41. The first spring 41 absorbs the energy and reduces the damage to the main body 1 of the transport vehicle and the materials and equipment.
