Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying devices, specifically to a conveying device for tunnel construction materials. Background Technology
[0002] In narrow tunnel construction sites, due to limited working space, large machinery and transportation equipment cannot enter. All construction materials, such as steel bars, concrete, and support components, must be transported manually, carried by hand. This primitive method of handling is not only extremely inefficient, severely slowing down the project progress, but also poses a huge challenge to the workers' physical strength. Long-term high-intensity carrying of heavy loads through dimly lit and bumpy tunnels can easily lead to physical exhaustion, increasing the risk of muscle strain and falls, resulting in significant safety hazards. At the same time, the small carrying capacity and poor continuity of manual handling often lead to work stoppages due to material shortages, becoming a key bottleneck restricting the overall project schedule and cost.
[0003] Therefore, there is an urgent need to provide a safe and efficient material transport device. Utility Model Content
[0004] The purpose of this invention is to provide a simple, easy-to-operate, safe and efficient tunnel construction material transport device.
[0005] To achieve the above objectives, this utility model provides a tunnel construction material transport device, comprising: a wire rope, a pulley assembly, two fixing devices, and two drag ropes; the two fixing devices are arranged along the extension direction of the tunnel and fixed between the two side walls of the tunnel; the two ends of the wire rope are respectively connected to the two fixing devices, the pulley assembly is slidably connected between the two ends of the wire rope, the first end of each of the two drag ropes is respectively connected to the pulley assembly, and the second end of each of the two drag ropes extends in the direction of the two fixing devices, the drag ropes can pull the pulley assembly to move along the extension direction of the wire rope, and the pulley assembly is provided with a hook; the fixing device includes a fixing rod and a fixing sleeve, the first end of the fixing rod is inserted into the fixing sleeve from the first end of the fixing sleeve, the depth of the fixing rod inserted into the fixing sleeve is adjustable, and the second ends of the fixing rod and the fixing sleeve are respectively connected to the two side walls of the tunnel.
[0006] As can be seen from the above scheme, the above setup facilitates the transportation of construction materials in narrow tunnels, which reduces the labor intensity of construction workers, improves work efficiency, and saves time. By setting up fixing rods and fixing sleeves, the length of the fixing device can be easily adjusted according to the width of the tunnel, ensuring that the fixing device can be fixed between the two side walls of the tunnel, which is conducive to compatibility with tunnels of different widths and improves its practicality.

[0008] A further option is to provide an inclined surface on the outer peripheral wall of the elastic block, with the inclined surface extending outward from the connecting end of the elastic block toward its free end.
[0009] A further option is to provide a threaded portion on the outer side of the fixed sleeve, with the threaded portion extending at least partially to the outer peripheral wall of the elastic block, and the locking fastener being threadedly connected to the threaded portion.
[0010] A further option is to wrap the end of the wire rope around the fixed sleeve and place it on the side of the locking fastener facing away from the elastic block.

[0014] A further embodiment is that the pulley assembly includes a pulley seat, a pin, and a pulley. The pulley is rotatably connected to the pulley seat via the pin. The wire rope is connected to the pulley, and the hook is connected to the bottom of the pulley seat.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0022] See Figures 1 to 5 The tunnel construction material transport device provided in this embodiment includes: a wire rope 1, a pulley assembly 2, two fixing devices 3, and two drag ropes 4.
[0023] Two fixing devices 3 are arranged along the extension direction of the tunnel 10 and respectively installed at both ends of the tunnel 10 in the length direction. The fixing devices 3 are fixed between the two side walls of the tunnel. The length of the fixing devices 3 is adjustable. On the one hand, the length can be adjusted according to the actual width of the tunnel 10 to ensure that the fixing devices 3 can be stably fixed between the two side walls of the tunnel 10. On the other hand, it can be compatible with tunnels 10 of different widths to improve its practicality.
[0024] The two ends of the wire rope 1 are connected to two fixed devices 3 respectively, and the wire rope 1 extends along the extension direction of the tunnel 10. The pulley assembly 2 is slidably connected between the two ends of the wire rope 1. The first end of each of the two drag ropes 4 is connected to the pulley assembly 2 respectively, and the second end of each of the two drag ropes 4 extends in the direction of the two fixed devices 3 respectively, that is, the second end of the drag rope 4 extends to the outside of the tunnel 10, so that construction workers can stand on the outside of the tunnel 10 to pull the drag rope 4.
[0025] Two towing ropes 4 pull the pulley assembly 2 back and forth along the extension direction of the wire rope 1. The pulley assembly 2 is equipped with hooks 24 for lifting construction materials and transporting them to the other end of the tunnel 10.
[0026] The fixing device 3 includes a fixing rod 31, a fixing sleeve 32, and a locking device 33. At least two elastic blocks 321 are provided at the first end of the fixing sleeve 32. In this embodiment, four elastic blocks 321 are used as an example. The four elastic blocks 321 form a circular hole, with a gap between adjacent elastic blocks 321. The elastic blocks 321 can elastically swing inwards towards the fixing sleeve 32. The elastic blocks 321 and the fixing sleeve 32 are integrally formed. The fixing sleeve 32 and the elastic blocks 321 are preferably made of an elastic metal material.
[0027] The first end of the fixing rod 31 is inserted into the fixing sleeve 32 from the first end of the fixing sleeve 32, and the depth of the fixing rod 31 inserted into the fixing sleeve 32 is adjustable. The locking fastener 33 is sleeved on the outside of the fixing sleeve 32 and can force the elastic block 321 to swing inward to lock the fixing rod 31.
[0028] The outer peripheral wall of the elastic block 321 is provided with an inclined surface 3211, which extends outward from the connecting end of the elastic block 321 toward its free end.
[0029] The outer side of the fixed sleeve 32 is provided with a threaded portion (not shown in the figure), which extends at least partially to the outer peripheral wall of the elastic block 321.
[0030] The locking fastener 33 is preferably a nut, and the locking fastener 33 is threadedly connected to the threaded part. By turning the locking fastener 33, the locking fastener 33 moves to the side where the free end of the elastic block 321 is located, thereby pushing the elastic block 321 to swing inward. The inner wall of the elastic block 321 fits tightly against the outer wall of the fixing rod 31, thereby achieving a locking effect.
[0031] The end of the wire rope 1 is wrapped around the outside of the fixed sleeve 32 and set on the side of the locking fastener 33 facing away from the elastic block 321, so as to provide enough space for the movement of the locking fastener 33.
[0032] The fixing device 3 also includes a first fixing pad 34 and a second fixing pad 35. The first fixing pad 34 is connected to the second end of the fixing sleeve 32, and the first fixing pad 34 is fixedly connected to the fixing sleeve 32 or detachably connected. The second fixing pad 35 is connected to the second end of the fixing rod 31, and the second fixing pad 35 is fixedly connected to the fixing rod 31 or detachably connected. The outer diameter of the first fixing pad 34 is greater than or equal to the outer diameter of the fixing sleeve 32, and the outer diameter of the second fixing pad 35 is greater than or equal to the outer diameter of the fixing rod 31. The first fixing pad 34 and the second fixing pad 35 directly abut against the side walls of the tunnel 10 to increase the friction between them. The first fixing pad 34 and the second fixing pad 35 can be made of plastic, rubber, wood, or metal.
[0033] To further accommodate more tunnels 10 of different widths, the fixing device 3 also includes several fixing rods 31, each of which has a different length. All fixing rods 31 are detachably connected to the fixing sleeve 32 in one of the following ways.
[0034] exist Figure 1 In this assembly, pulley assembly 2 includes pulley seat 21, pin 22, and pulley 23. Pulley seat 21 includes a base plate and two opposing side plates. Pulley 23 is rotatably connected to the two side plates of pulley seat 21 via pin 22. Wire rope 1 is positioned below and connected to pulley 23. Hook 24 is connected to the base plate of pulley seat 21 for lifting construction materials.
[0035] Hanging rings 211 are provided on both sides of the base plate of the pulley seat 21. The first ends of the two drag ropes 4 are connected to the two hanging rings 211 respectively, so as to facilitate the movement of the pulley assembly 2.
[0036] In summary, the present invention, through the above-mentioned design, facilitates the transportation of construction materials in narrow tunnels 10, thereby reducing the labor intensity of construction workers, improving work efficiency, and saving time. By setting up a fixing rod and a fixing sleeve, the length of the fixing device can be easily adjusted according to the width of the tunnel 10, ensuring that the fixing device can be fixed between the two side walls of the tunnel 10, which is beneficial for compatibility with tunnels 10 of different widths and improves its practicality.
[0037] Finally, it should be emphasized that the above are only preferred embodiments of this utility model and are not intended to limit this utility model.
