Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a coal transport cart for preventing spontaneous combustion of coal. Background Technology

[0002] As a vital basic energy source and industrial raw material, coal requires crucial safety management during its mining, storage, and transportation. Spontaneous combustion of coal is a long-standing and significant safety hazard. During transportation, coal, piled in relatively enclosed wagons, undergoes a slow oxidation reaction with oxygen in the air, releasing heat. Under the combined effects of direct sunlight and rising ambient temperatures, if this heat cannot dissipate quickly enough, the internal temperature of the coal pile will continuously accumulate, eventually leading to spontaneous combustion. This not only causes enormous losses of coal resources and property but also has the potential to trigger fires or even explosions, seriously threatening production safety and human lives.

[0003] Currently, most coal transport carts lack effective heat insulation measures. Under direct sunlight, the temperature of the cart body rises rapidly, directly providing an external heat source for the coal pile and accelerating its internal heating process. Furthermore, existing coal transport carts lack a mechanism for actively and evenly cooling the coal during transportation. Once the temperature is found to be too high, transportation can only be stopped for treatment, which is inefficient and cannot prevent spontaneous combustion of coal. Therefore, we propose a coal transport cart designed to prevent spontaneous combustion of coal. Utility Model Content

[0004] The purpose of this invention is to provide a coal transport trolley for preventing spontaneous combustion of coal, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal transport trolley for preventing spontaneous combustion of coal, comprising a base, a vehicle body fixedly connected to the top of the base, and a cover connected to the top of the vehicle body, water pipes equidistantly installed at one end of the vehicle body, and connecting pipes connecting multiple water pipes, an inlet for connecting to an external water supply pipe being provided at the end of the connecting pipe, water spray nozzles equidistantly arranged outside the water inlet, and the ends of the water spray nozzles extending into the interior of the vehicle body, and a sunshade film that can be unfolded and rolled up being provided on the top of the vehicle body.

[0006] Preferably, a mounting box is fixedly connected to one end of the vehicle body at the connecting pipe, and a winding shaft is rotatably connected to the mounting box via a bearing. A strip groove is provided on one side of the mounting box, and one end of the sunshade film passes through the strip groove and is wound up to the outside of the winding shaft. Both ends of the winding shaft pass through the mounting box and are fixedly connected to a drive pulley. A driven pulley is rotatably connected to the end of the vehicle body sidewall away from the drive pulley. The drive pulley and the driven pulley are connected by a belt drive. A fixing rod is symmetrically fixed to one end of the sunshade film outside the vehicle body, and the fixing rod is fixedly connected to the belt.

[0007] Preferably, protective boxes are fixedly connected to the top of the corresponding two side walls of the vehicle body. The driving pulley and the driven pulley are both located inside the protective boxes. The fixing rod has an overall L-shaped structure and is slidably connected to the outside of the protective box. A drive motor is fixedly installed on the outside of the protective box at one end of the vehicle body, and the output shaft end of the drive motor passes through the protective box and is fixedly connected to the central shaft of the driving pulley.

[0008] Preferably, a fixing box is fixedly installed on the surface of the protective box, and the drive motor is located inside the fixing box.

[0009] Preferably, drive wheels are symmetrically mounted at one end of the bottom of the vehicle body, a transmission rod is fixed between the central shafts of the two drive wheels, and the transmission rod is rotatably connected to the bottom of the vehicle body through a bearing. A drive component for driving the transmission rod to rotate is installed at the bottom of the vehicle body, and a steering wheel is installed at the middle of the bottom of the vehicle body away from the drive wheels.

[0010] Preferably, a push frame is fixedly connected to one end of the water pipe at the top of the base, and a push handle is symmetrically fixedly connected to the top of the push frame, and an anti-slip sleeve is provided on the outside of the push handle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model constructs a dual protection mechanism combining "passive heat insulation" and "active cooling" through the synergistic effect of an deployable sunshade film and a built-in water spray system. The sunshade film effectively blocks direct sunlight, reducing the input of external heat at the source; while when the internal temperature of the coal pile rises, the water spray system can directly spray water onto it, achieving rapid and uniform cooling. This dual measure can significantly inhibit the oxidation and heating process of coal, fundamentally and effectively preventing the risk of spontaneous combustion of coal during transportation.

[0013] 2. This utility model achieves one-click automatic unfolding and rewinding of the sunshade film through the cooperation of a drive motor, pulley assembly and winding shaft, avoiding the tedious manual laying and storage, simple operation, saving time and effort, and greatly improving the efficiency of transportation operations.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a coal transport cart for preventing spontaneous combustion of coal, including a base 1, a cart body 4 fixedly connected to the top of the base 1, and a cart cover 5 connected to the top of the cart body 4. Water pipes 9 are installed at equal intervals at one end of the cart body 4, and connecting pipes 11 are connected between multiple water pipes 9. The end of the connecting pipe 11 is provided with a water inlet 12 for connecting to an external water supply pipe. Water nozzles 2 are provided at equal intervals on the outside of the water inlet 12, and the ends of the water nozzles 2 extend into the interior of the cart body 4. A sunshade film 8 that can be unfolded and rolled up is provided on the top of the cart body 4.

[0020] Please see Figure 2 The vehicle body 4 is fixedly connected to one end of the connecting pipe 11 with a mounting box 6, and a winding shaft 7 is rotatably connected inside the mounting box 6 via a bearing. A strip groove is opened on one side of the mounting box 6. One end of the sunshade film 8 passes through the strip groove and is wound up on the outside of the winding shaft 7. Both ends of the winding shaft 7 pass through the mounting box 6 and are fixedly connected to a drive pulley 16. A driven pulley 17 is rotatably connected to the side wall of the vehicle body 4 away from the drive pulley 16. The drive pulley 16 and the driven pulley 17 are connected by a belt drive. A fixing rod 18 is symmetrically fixed to one end of the sunshade film 8 located outside the vehicle body 4. The fixing rod 18 is fixedly connected to the belt.

[0021] It should be noted that, in the initial state of use, the sunshade film 8 is wound up on the winding shaft 7 inside the mounting box 6. After opening the vehicle cover 5 and placing the coal to be transported inside the vehicle body 4, the drive motor 20 is controlled to work, driving the drive pulley 16 to rotate. Through the transmission connection between the drive pulley 16 and the driven pulley 17, the belt moves outside the drive pulley 16 and the driven pulley 17, which moves the fixing rod 18 at the end of the sunshade film 8, so that the sunshade film 8 outside the winding shaft 7 is unfolded. At the same time, the two fixing rods 18 pull the end of the sunshade film 8 to unfold, so that the sunshade film 8 can cover the top of the vehicle body 4, preventing the coal from spontaneously combusting due to sun exposure. When the internal temperature of the coal is too high, the external water supply pipe can be connected to the water inlet 12 to supply an appropriate amount of water to the inside of the vehicle body 4 to cool it down and prevent the coal from spontaneously combusting due to excessive temperature.

[0022] Please see Figure 2 The top of each side wall of the vehicle body 4 is fixedly connected to a protective box 19. The driving pulley 16 and the driven pulley 17 are both located inside the protective box 19. The fixing rod 18 is in an L-shaped structure and is slidably connected to the outside of the protective box 19. A drive motor 20 is fixedly installed on the outside of the protective box 19 at one end of the vehicle body 4, and the output shaft end of the drive motor 20 passes through the protective box 19 and is fixedly connected to the central shaft of the driving pulley 16.

[0023] It should be noted that the protective box 19 can protect the driving pulley 16 and the driven pulley 17. The driving motor 20 can drive the driving pulley 16 to rotate. Through the transmission connection between the driving pulley 16 and the driven pulley 17, the fixing rod 18 can slide along the protective box 19. The fixing rod 18 pulls the sunshade film 8 to cover the top of the vehicle body 4 to prevent the coal from being exposed to the sun.

[0024] Please see Figure 2 A fixed box 10 is fixedly installed on the surface of the protective box 19, and the drive motor 20 is located inside the fixed box 10.

[0025] It should be noted that the mounting box 10 can protect the drive motor 20 and prevent dust from accumulating on the drive motor 20.

[0026] Please see Figure 2 One end of the bottom of the vehicle body 4 is symmetrically equipped with drive wheels 3. A transmission rod is fixed between the central shafts of the two drive wheels 3, and the transmission rod is rotatably connected to the bottom of the vehicle body 4 through a bearing. A drive component for driving the transmission rod to rotate is installed at the bottom of the vehicle body 4. A steering wheel 15 is installed at the middle of the bottom of the vehicle body 4 away from the drive wheels 3.

[0027] It should be noted that the trolley can be moved by the drive wheel 3 and the steering wheel 15, ensuring that the vehicle still has good mobility when loaded.

[0028] Please see Figure 2 The top of the base 1 is fixedly connected to one end of the water pipe 9, and the top of the push frame 13 is symmetrically fixedly connected to the push handle 14, and the outside of the push handle 14 is provided with an anti-slip sleeve.

[0029] It should be noted that the coordinated arrangement of the pusher 13 and its push handle 14 can control the movement direction and steering of the car body 4, facilitating better transportation of coal.
