Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal transport vehicle technology, specifically a coal transport vehicle anti-spillage device. Background Technology
[0002] Spillage and dust pollution are long-standing and serious problems during the transportation of bulk materials such as coal and ore. When coal trucks travel at high speeds, the materials loaded inside the carriages, especially fine coal dust, are highly susceptible to leakage due to external airflow. This not only causes direct economic losses and cargo damage, but also severely pollutes the environment along railway lines and highways, damages equipment, affects traffic safety, and incurs huge environmental remediation costs.
[0003] When a vehicle travels at high speed, air flows over the open top of the cargo compartment. According to Bernoulli's principle, the faster the flow, the lower the fluid pressure. The air above the compartment has a high velocity and low pressure, while the air inside the compartment is relatively still and has high pressure. This pressure difference creates a strong upward suction force, continuously drawing out lightweight, fine coal dust from any possible gaps, forming a noticeable dust pollution band behind the vehicle. Existing technologies, due to inadequate sealing and the inability to reliably cover the entire area, have failed to effectively block this airflow suction process. This results in leakage of coal during the vehicle's operation due to airflow. Therefore, we propose a coal truck spill prevention device. Utility Model Content
[0004] The purpose of this utility model is to provide a coal truck anti-spillage device, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A coal truck spill prevention device includes a truck body; The vehicle body is equipped with protective and storage mechanisms; The protective mechanism includes a storage rack located on the exterior wall of the vehicle. A take-up roller is rotatably connected inside the storage rack, and a protective cloth is wound around the take-up roller. A guide wheel is fixedly connected to the end of the protective cloth, and a traction rope is connected to the guide wheel.
[0006] Preferably, a take-up reel is connected to the outer wall of the vehicle body, a drive device is connected to one end of the take-up reel, the end of the traction rope is fixedly connected to the take-up reel, and two take-up rollers and two take-up reels are provided.

[0015] 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.
[0016] Example 1 A coal truck anti-spillage device, such as Figures 1-4 As shown, it includes a vehicle body 1; the vehicle body 1 is equipped with a protective mechanism 2, which can protect the coal pile stored inside the vehicle body 1 and cover the top of the coal pile during transportation, thereby reducing the leakage of coal pile caused by airflow during transportation.
[0017] Specifically, the protective mechanism 2 includes a storage rack 201, which is located on the outer wall of the vehicle body 1. A take-up roller 202 is rotatably connected inside the storage rack 201. A protective cloth 203 is wound around the take-up roller 202. A guide wheel is fixedly connected to the end of the protective cloth 203. A traction rope 205 is connected to the guide wheel. The storage rack 201 can store and support the take-up roller 202, allowing the take-up roller 202 to rotate. At the same time, the take-up roller 202 can store the protective cloth 203. The guide wheel can pull the end of the protective cloth 203, allowing the end of the protective cloth 203 to slide along the coal pile and unfold to protect the coal pile.
[0018] In addition, a winding wheel 206 is connected to the outer wall of the vehicle body 1. One end of the winding wheel 206 is connected to a drive device 207. The end of the traction rope 205 is fixedly connected to the winding wheel 206. Two winding rollers 202 and two winding wheels 206 are provided. The winding wheel 206 can wind up the traction rope 205, thereby using the winding force of the winding wheel 206 to pull and wind up the traction rope 205. One winding wheel 206 is located above the storage rack 201 on the corresponding side of the vehicle body 1, and the other winding wheel 206 is located below the storage rack 201 on the corresponding side of the vehicle body 1, so that the protective cloth 203 on one side covers the protective cloth 203 on the other side, so that when the ends of the two protective cloths 203 move towards each other, there is no movement interference that affects the shielding of the coal pile. The drive device 207 is a motor or a rocker arm. In this embodiment, the drive device 207 is a motor, and the motor is connected when loading and unloading cargo on the vehicle body 1.
[0019] Furthermore, a coil spring 208 is fixedly connected to one end of the take-up roller 202, a limit groove 209 is provided at the bottom of the storage rack 201, and a guide rod 210 is rotatably connected to the bottom side of the storage rack 201. The coil spring 208 structure can provide elasticity to the take-up roller 202. The coil spring 208 can cooperate with the take-up wheel 206 to tighten the protective cloth 203, thereby protecting the coal pile.
[0020] Example 2 like Figures 1-3 As shown, based on Embodiment 1, the vehicle body 1 is provided with a storage mechanism 3, which can store the protective cloth 203.
[0021] In this embodiment, the storage mechanism 3 includes a baffle 301, which is fixedly connected to the top of the vehicle body 1. A storage ring 302 is connected to the baffle 301, and a traction rope 205 is set through the storage ring 302. A storage rope 303 is fixedly connected to the storage ring 302. The baffle 301 can block both ends of the vehicle body 1, so that the coal pile protruding in the middle can be blocked by inertial movement when the vehicle body 1 is running.
[0022] Based on this, a movable groove is provided on the receiving ring 302, and the protective cloth 203 is connected inside the movable groove. The diameter of the traction rope 205 is larger than the width of the movable groove. The receiving ring 302 can position the traction rope 205 so that the traction rope 205 is at the top of the baffle 301 during loading and unloading, so as to avoid blocking the feeding of coal blocks and causing leakage.
[0023] It is worth noting that a discharge gate is rotatably connected to the bottom of the vehicle body 1, and the end of the storage rope 303 is fixedly connected to the discharge gate. The discharge gate structure can unload the coal pile, and the storage rope 303 fixed to the discharge gate can automatically hang the storage rope 303 on the top of the baffle 301 during the discharge.
[0024] In use, the coal spill prevention device for a coal transport vehicle of this utility model first feeds the coal pile from the top of the vehicle body 1. Upon completion of feeding, the center of the coal pile bulges. Then, the drive device 207 drives the winding wheel 206 to rotate, which in turn winds up the traction rope 205. Simultaneously, due to the elasticity of the coil spring 208, both ends of the traction rope 205 are subjected to traction force, pulling the storage ring 302 above the vehicle body 1. The taut traction rope 205 adapts to the shape of the coal pile top, allowing the protective cloth 203 to fit snugly against the top of the coal pile. During transportation, the taut protective cloth 203 can shield the coal pile, reducing spillage caused by airflow, and also prevents swaying caused by airflow. When unloading is completed, the unloading gate opens and the receiving rope 303 is pulled downwards. The other end of the receiving rope 303 rises accordingly, driving the receiving ring 302 upwards until the receiving ring 302 and the traction rope 205 move to the top of the baffle 301. At this time, the protective cloth 203 forms an arched structure to prevent the protective cloth 203 from sinking downwards along with the coal pile when unloading. At the same time, the arched protective cloth 203 can cooperate with the baffle 301 to cover the top of the vehicle body 1, preventing dust generated by the coal pile from escaping from the top of the vehicle body 1 during unloading.
