It has strong practicality and reliability.

[0020] 2. By setting up a winding section, when in use, the material is placed inside the delivery trolley, and the locking lever is pulled to disengage it from the locking ring. The locking lever drives the circular plate to compress the spring, causing it to deform and store energy, and then pulls the rainproof cloth to cover the top of the delivery trolley. After releasing the locking lever, the spring releases its elasticity and pushes the circular plate back to its original position, causing the locking lever to engage with the locking ring, thus fixing the winding roller to maintain the rainproof cloth's coverage. When winding the rainproof cloth, the locking lever is pulled again to disengage it from the locking ring, and the crank handle is turned to drive the winding roller to rotate, winding the rainproof cloth onto the roller body. After winding is complete, the locking lever is released, allowing it to re-engage with the locking ring to fix the winding roller, preventing the rainproof cloth from loosening and stabilizing the winding roller's state. This ensures that the rainproof cloth does not fall off when covering and also prevents it from becoming loose and scattered after winding.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this embodiment provides a tunnel construction material delivery device, including a delivery trolley 111, and further comprising:

[0033] The fixing part 2 is mounted on the delivery trolley 111. The fixing part 2 includes a fixing component 21 and a pressing component 22. The fixing component 21 includes a support plate 211 and a binding roller 212. The support plate 211 is connected to the delivery trolley 111 and is used to install the binding roller 212. The binding roller 212 is rotatably connected to the support plate 211. Its rotation can be driven by conventional manual or motor shaft rotation. In this application, the binding roller 212 is used for winding and unwinding. The pressing component 22 is adapted to the fixing component 21 and is used to limit the rotation of the binding roller 212. A binding rope 314 is wound on the binding roller 212.

[0034] The winding section 3 is mounted on the delivery trolley 111 corresponding to the fixing section 2. The winding section 3 includes a winding assembly 31 and a locking assembly 32. The winding assembly 31 includes a winding roller 312 and a rainproof cloth 313. The rainproof cloth 313 is wound on the winding roller 312, and the unwinding end of the rainproof cloth 313 is connected to the binding rope 314. The end of the winding roller 312 is connected to the locking assembly 32. A crank handle 315 is provided on the end of the winding roller 312, and the crank handle 315 is located on the same side as the locking assembly 32.

[0035] Compared to directly designing both ends of the rainproof cloth 313 as an integral winding drum structure, which is prone to irregular winding during long-term use, thus affecting the service life of the equipment or increasing maintenance costs, this embodiment sets a retractable binding rope 314 at one end of the rainproof cloth 313. The binding rope 314 can flexibly wind and unwind, ensuring the stability of the rainproof cloth 313 during use. Through the winding and unwinding cooperation of the binding roller 212 and the winding roller 312, the rain protection operation of the material can be quickly responded to. The setting of the fixing part 2 and the locking component 32 makes the fixing of the rainproof cloth 313 more convenient and reliable, effectively preventing the material from falling off due to bumps during transportation. In this embodiment, each driving component can be set as a structure that does not require electric power, saving energy costs and reducing the problems of delivery safety and reliability.

[0036] In this embodiment, as Figure 2 and Figure 3 As shown, the extrusion assembly 22 includes two sets of limiting brackets 214 and fixing plates 216 arranged symmetrically on both sides of the binding roller 212. The limiting brackets 214 and the fixing plates 216 are connected by telescopic rods 215. Specifically, six telescopic rods 215 can be equidistantly arranged, and each set of fixing plates 216 is fixedly connected to three telescopic rods 215. An extrusion protrusion 222 is also provided between the two fixing plates 216 located symmetrically on both sides of the binding roller 212. The two fixing plates 216 can reciprocate relative to each other during the rotation of the extrusion protrusion 222. By manually rotating the extrusion protrusion 222, the opening and closing of the fixing plates 216 symmetrically arranged on both sides of the binding roller 212 can be realized, thereby clamping and fixing the binding roller 212 and loosening and unwinding it, which is convenient to operate.

[0037] Furthermore, each binding roller 212 is provided with two support plates 211, and the two ends of the binding roller 212 are respectively rotatably mounted on the corresponding support plates 211; the support plate 211 near the extrusion protrusion 222 is provided with a groove 213 adapted to the extrusion assembly 22, and the fixing plate 216 passes through its corresponding groove 213 and contacts the extrusion protrusion 222. In this embodiment, a strong spring 217 is sleeved on the telescopic rod 215; and / or, a crank handle 223 is connected to the rotation center of the extrusion protrusion 222 through a rotating rod 221 for telescopic extension. Turning the crank handle 223 drives the pressing protrusion 222 to rotate. The pressing protrusion 222 pushes the fixed plate 216 to move and presses the telescopic rod 215 and the strong spring 217 to deform and store energy, causing the limiting bracket 214 to slide along the slide groove 213 away from the binding roller 212. After the binding rope 314 of the rainproof cloth 313 is wrapped around the binding roller 212, the limiting bracket 214 is pushed to reset, so that the two fixed plates 216 are on both sides of the binding roller 212. Turning the crank handle 223 in the opposite direction resets the pressing protrusion 222, and the strong spring... 217 releases the elastic force to push the two fixing plates 216 to move towards each other, clamping the binding rope 314 on the binding roller 212, thereby fixing the rainproof cloth 313 to the delivery cart 111, realizing the quick fixing and disassembly of the binding rope 314. The operation is convenient and efficient, reducing the intensity of manual operation. The binding rope 314 is wrapped around the binding roller 212, and with the clamping action of the fixing plate 216, it improves the fixing stability of the rainproof cloth 313, effectively preventing the material from falling off due to bumps during transportation, and has strong practicality and reliability.

[0038] In this embodiment, the limiting brackets 214 on both sides of the binding roller 212 are slidably engaged on the support plate 211. The two support plates 211 can be a C-shaped integral structure, which facilitates the consistency of structural movement. The limiting brackets 214 and the fixing plate 216 can slide out of the groove 213 when pulled by external force, so as to facilitate the use of the binding roller 212 and the maintenance and disassembly of the equipment.

[0039] In this embodiment, as Figure 1 As shown, there are two sets of fixing parts 2, which are set at the same horizontal position on the delivery trolley 111. The two binding ropes 314 on the two sets of fixing parts 2 are respectively connected to both sides of the unwinding end of the rainproof cloth 313 to ensure the stability of the structure. Furthermore, baffles 311 are provided on both sides of the winding roller 312. The baffles 311 are fixed on the outer wall of the delivery trolley 111. The winding roller 312 passes through the baffles 311 and is connected to the locking assembly 32. The baffles 311 can limit the winding roller 312 from winding the rainproof cloth 313, preventing the rainproof cloth 313 from swinging during the winding process and causing unstable winding.

[0040] In this embodiment, such as Figure 6As shown, the locking assembly 32 includes a locking ring 321 fixedly connected to the outer wall of the take-up roller 312; the locking ring 321 is provided with a plurality of locking holes; a fixing block 322 is fixedly provided on the baffle 311, and a locking rod 323 is slidably connected to the fixing block 322, the locking rod 323 being adapted to the locking holes. The locking rod 323 is provided with a reset component, which includes a circular plate 324 and a spring 325. The circular plate 324 is fixedly connected to the outer wall of the locking rod 323, and the spring 325 is located between the fixing block 322 and the circular plate 324 and is sleeved on the outer wall of the locking rod 323. When it is necessary to lock the take-up roller 312, it is only necessary to insert the locking rod 323 into the locking hole directly below it to achieve locking. By setting the reset component on the locking rod 323 and utilizing the clamping force of the spring 325, fast and secure locking can be achieved.

[0041] A specific usage process of this embodiment is as follows: During use, materials are placed into the delivery trolley 111. Then, the locking lever 323 is pulled away from the locking ring 321. The locking lever 323 causes the circular plate 324 to compress the spring 325, causing it to deform and generate elasticity. This pulls the rainproof cloth 313, covering the top of the delivery trolley 111. Releasing the locking lever 323 eliminates the compressive force on the spring 325, releasing the elasticity. The elasticity acts on the circular plate 324, causing the locking lever 323 to engage with the locking ring 321, fixing the take-up roller 312. Then, the roller is rotated... The crank 223, via the rotating rod 221, drives the pressing protrusion 222 to rotate. The pressing protrusion 222 pushes the fixed plate 216 to move. The fixed plate 216 presses the telescopic rod 215 and the strong spring 217, causing the strong spring 217 to deform and generate elastic force, pulling the limiting bracket 214 out of the slide groove 213. The limiting bracket 214 moves the fixed plate 216 away from the binding roller 212, and then the binding rope 314 on the rainproof cloth 313 is wrapped around the binding roller 212, increasing the contact area between the binding rope 314 and the binding roller 212, increasing the friction. The push-limit bracket 214 is reset, which moves the two fixed plates 216 to both sides of the binding roller 212. Then, the crank handle 223 is turned to reset the pressing protrusion 222, the pressing force on the strong spring 217 disappears, and the elastic force is released. The elastic force acts on the fixed plates 216, and the two fixed plates 216 move closer to each other, fixing the binding rope 314 on the binding roller 212 and fixing the rainproof cloth 313 to the delivery cart 111 to prevent the material from being thrown out during transportation. When it is necessary to take out the material from the delivery cart 111, it is done by... The reverse operation moves the two fixed plates 216 away from the binding roller 212, removes the binding rope 314 from the binding roller 212, then pulls the locking rod 323 away from the locking ring 321, turns the crank handle 315, and the crank handle 315 drives the winding roller 312 to rotate. The winding roller 312 winds up the rainproof cloth 313. After winding, the locking rod 323 is released, so that the locking rod 323 is engaged with the locking ring 321. Under the action of the locking rod 323 and the locking ring 321, the winding roller 312 is fixed to prevent the rainproof cloth 313 from loosening after winding.
