Description

Technical Field

[0001] The invention relates to the technical field of mining vehicles, and in particular to an explosion-proof underground mining road surface washing, sweeping and suction integrated vehicle. Background Art

[0002] Because there are many dust particles in the mine, the road surface is very likely to be attached with a lot of debris, which may affect the safety of vehicles traveling underground. To solve this problem, road sweepers are usually deployed underground to clean the underground road surface. Road sweepers are usually equipped with flushing devices that can flush the road surface to improve the cleaning effect. The flushing device is usually a water tank installed on the road sweeper. The water in the water tank is pumped out by a water pump and sprayed onto the road surface through a nozzle.

[0003] However, when a road sweeping vehicle is operating underground, it is bound to operate on a sloping road surface. When sweeping the road surface in the uphill and downhill processes, the water level line in the water tank in the vehicle will be inclined relative to the water tank. When the water level in the water tank is low, dead corners will appear in the tank, and the water pump cannot pump out the remaining water in the dead corners, resulting in difficulty in fully utilizing the water stored in the vehicle. Summary of the invention

[0004] In view of this, the present invention aims to propose an explosion-proof underground road washing, sweeping and sucking integrated vehicle for use in mines, so as to improve the utilization rate of the vehicle for the stored water.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A mining explosion-proof underground road washing, sweeping and suction integrated vehicle, comprising a vehicle body and a carriage mounted on the vehicle body, a water tank is arranged in the carriage, a first water outlet is arranged at the front end of the water tank in the vehicle travel direction, and a second water outlet is arranged at the other end opposite to the first water outlet, the first water outlet and the second water outlet are connected to the same header box, a discharge pipe is arranged at the bottom of the header box, the discharge pipe is connected to a water pump, and the water pump can supply water to water-using equipment on the vehicle;

[0007] The collecting box is provided with a partition that can rotate along a horizontal rotation axis, and the partition divides the inner cavity of the collecting box into two front and rear chambers. The first water outlet and the second water outlet are respectively connected to one of the chambers. The partition can rotate due to gravity when the water tank is tilted, so that the chamber connected to the lower end of the water tank is connected to the discharge pipe.

[0008] Furthermore, the first water outlet is connected to the chamber at the rear side, the second water outlet is connected to the chamber at the front side, and the center of gravity of the partition is located at the lower side of its rotation axis.

[0009] Furthermore, a limiting portion is provided in the collecting box to limit the rotatable angle of the partition.

[0010] Furthermore, the first water outlet is connected to the front chamber, the second water outlet is connected to the rear chamber, the center of gravity of the partition is located on the upper side of its rotation axis, and the collecting box is provided with a limiting portion to limit the rotatable angle of the partition.

[0011] Further, the vehicle includes a cleaning device and a first flushing device;

[0012] The cleaning device can be folded and arranged on the side of the vehicle body. The first flushing device is connected to the cleaning device and connected to the water pump, and can flush the road surface in front of the cleaning device when the cleaning device is deployed for cleaning.

[0013] Further, the vehicle includes a sewage suction device and a second flushing device;

[0014] The sewage suction device is arranged at the rear end of the vehicle body, and includes a traveling assembly and a sewage suction pipe. The sewage suction pipe is connected to the traveling assembly and can suck dirt on the ground. A negative pressure box for containing dirt is also provided in the vehicle compartment, and the sewage suction pipe is connected to the negative pressure box. The second flushing device is connected to a water pump and can flush the ground sucked by the sewage suction pipe.

[0015] Further, the vehicle includes a first engine, a transmission and a fan;

[0016] The output end of the first engine is connected to a transmission device, the transmission device is connected to and drives the fan and the water pump to work, and the suction port of the fan is connected to the negative pressure box.

[0017] Furthermore, the outlet end of the sewage suction pipe extends upward after passing through the negative pressure box, a protective plate is provided on the inner top wall of the negative pressure box, and the outlet end of the sewage suction pipe faces the protective plate.

[0018] Furthermore, the inner bottom wall of the negative pressure box is inclined, and a third flushing device is provided in the negative pressure box. The third flushing device is provided with a plurality of cleaning nozzles, and the directions of the cleaning nozzles have different angles with the inner bottom wall.

[0019] Furthermore, at least two filters are provided between the water pump and the discharge pipe, and the filtering accuracy of the filters is gradually improved along the water flow direction.

[0020] Furthermore, the equipment on the vehicle is all explosion-proof equipment for mining.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] When the vehicle described in the present invention is going uphill, the water in the water tank is concentrated at the second water outlet, and when the vehicle is going downhill, the water in the water tank flows to the first water outlet, which greatly reduces the dead angle in the water tank. Regardless of whether the vehicle is traveling uphill or downhill, the water pump can normally pump out the water in the corner, thereby improving the utilization rate of the stored water by the vehicle; and because when the water level in the water tank is low, air is likely to enter the water pump at either the first water outlet or the second water outlet, affecting the pumping efficiency of the water pump, the partition portion is provided to cut off the communication between the corresponding chamber and the discharge pipe when water cannot be discharged from the first water outlet or the second water outlet, thereby reducing the amount of air entering the water pump from the discharge pipe.

[0023] Secondly, the first water outlet is connected to the rear chamber, and the second water outlet is connected to the front chamber. The center of gravity of the partition is located at the lower side of its rotation axis, which can make the partition rotate automatically under the action of gravity and switch the connection relationship between the two chambers and the discharge pipe. The setting of the limit part can prevent the partition from excessive rotation and cut off the drainage function of the discharge pipe, and does not affect the normal operation of the collecting box. Setting the center of gravity of the partition at the lower part of its rotation axis can also realize the automatic rotation of the partition. The provision of the cleaning device and the first flushing device can make the vehicle have a better cleaning effect on the bottom surface, which is conducive to removing dirt adhering to the bottom surface.

[0024] Furthermore, the sewage suction device is arranged at the rear end of the vehicle body, which can make the sucked dirt gather at the rear end of the vehicle, so that the dirt can be discharged from the tailgate of the vehicle later. At the same time, the rear space of the vehicle is large, which can also facilitate the staff to inspect and repair the sewage suction device; the second flushing device can flush the bottom surface again to increase the amount of water on the road surface, so that the sewage suction device can suck away the dirt together with the sewage. The first engine drives the fan and the water pump at the same time, which improves the utilization rate of the first engine. The dirt sucked away by the sewage suction pipe and sent into the negative pressure box will fly out of the sewage suction pipe due to inertia, then hit the protective plate and fall into the inner bottom of the negative pressure box. The protective plate can not only protect the negative pressure box from the impact of the dirt, but also guide the dirt and sewage, so that the dirt and sewage fall quickly to the bottom of the negative pressure box.

[0025] In addition, the dirt and sewage sucked into the negative pressure box will be concentrated along the inner bottom wall of the negative pressure box to the rear door of the car, which is convenient for discharging the dirt and sewage; the third flushing device is equipped with multiple cleaning nozzles, and the orientation of each cleaning nozzle is different from the angle between the inner bottom wall, which can better flush the inner wall of the negative pressure box and remove the dirt attached to the inner wall, so that the inside of the negative pressure box is cleaner and more sanitary after the dirt and sewage are discharged. After the water in the water tank passes through several filters with gradually increasing filtration accuracy, it can reach a relatively clean level, making it difficult for each nozzle to be clogged. The equipment on the vehicle uses mining explosion-proof equipment, which can effectively prevent the occurrence of dangerous situations such as electrical sparks and high temperatures, thereby greatly reducing the risk of explosion.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0059] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0060] The present embodiment relates to an explosion-proof underground mining road surface washing, sweeping and suctioning vehicle, so as to improve the utilization rate of the vehicle's stored water.

[0061] In terms of overall structure, a mining explosion-proof underground road washing, sweeping and sucking vehicle in this embodiment includes a vehicle body and a carriage mounted on the vehicle body. A water tank is provided in the carriage. The water tank has a first water outlet at the front end in the direction of vehicle travel and a second water outlet at the other end. The first water outlet and the second water outlet are connected to the same collecting box. A discharge pipe is provided at the bottom of the collecting box. The discharge pipe is connected to a water pump, and the water pump can supply water to the water-using equipment on the vehicle.

[0062] A partition that can rotate along a horizontal rotation axis is provided on the collecting box. The partition divides the inner cavity of the collecting box into two front and rear chambers. The first water outlet and the second water outlet are respectively connected to a chamber. The partition can rotate due to gravity when the water tank is tilted, so that the chamber connected to the lower end of the water tank is connected to the discharge pipe.

[0063] As set up above, when the vehicle is going uphill, the water in the water tank can be concentrated at the second water outlet, and when the vehicle is going downhill, the water in the water tank can flow to the first water outlet, which greatly reduces the dead angle in the water tank. Regardless of whether the vehicle is going uphill or downhill, the water pump can normally pump out the water in the corner, thereby improving the utilization rate of the stored water in the vehicle. In addition, when the water level in the water tank is low, air is likely to enter the water pump at either the first water outlet or the second water outlet, affecting the pumping efficiency of the water pump. The partition can be set up to cut off the communication relationship between the corresponding chamber and the discharge pipe when the first water outlet or the second water outlet cannot discharge water, thereby reducing the air from entering the water pump from the discharge pipe.

[0064] Based on the above overall introduction, refer to Figures 1 to 3 As shown, the front direction of the vehicle is the front direction, and the other direction is the rear direction. Specifically, the carriage 2 is arranged at the rear of the vehicle body 1, and an equipment box 203 is also arranged above the middle of the vehicle body 1. The equipment box 203 is used to install equipment used by the vehicle. The header box 3 of this embodiment is arranged at the bottom of the carriage 2 and is located at the rear end of the carriage 2.

[0065] As a preferred embodiment, refer to Figure 2 and Figure 3As shown, the first water outlet 2011 is connected to the front chamber, the second water outlet 2012 is connected to the rear chamber, the center of gravity of the partition 4 is located on the upper side of its rotation axis, and the manifold 3 is provided with a limiter 304 to limit the rotatable angle of the partition 4. Specifically, the partition 4 is in sliding contact with the inner wall of the manifold 3 so that the two chambers do not interfere with each other. The chamber on the front side is the front chamber 302, and the chamber on the rear side is the rear chamber 303. The front chamber 302 is connected to a forward liquid pipe 306, which is arranged at the front side of the top of the manifold 3 and vertically downward into the manifold 3. The inner wall of the manifold 3 that is opposite to the position of the forward liquid pipe 306 is a guide arc surface 305, and the guide arc surface 305 can make the liquid flow through the manifold 3 more smoothly. The rear chamber 303 is connected to a rear liquid inlet pipe 307, which is arranged on the rear side of the top end of the collecting box 3 and vertically downward into the collecting box 3. The inner wall of the collecting box 3 opposite to the rear liquid inlet pipe 307 is a guide arc surface 305, which can make the liquid flow through the collecting box 3 more smoothly.

[0066] Secondly, the front liquid inlet pipe 306 is connected to the first water outlet 2011, and the rear liquid inlet pipe 307 is connected to the second water outlet 2012. The discharge pipe 301 is arranged in the middle of the bottom end of the collecting box 3, and the limit part 304 is arranged at the bottom of the collecting box 3, formed by the concave side wall of the collecting box 3, and arranged on both sides of the discharge pipe 301. In this embodiment, the partition 4 is plate-shaped, the upper part is a fan-shaped cross-section, and the lower part is a rectangular cross-section. The upper part of the partition 4 is heavier, so its center of gravity is on the upper side of its own rotation axis, so that it can rotate under the influence of gravity when the collecting box 3 is tilted. Of course, in this embodiment, the partition 4 can also adopt other shapes, as long as it can ensure that its center of gravity is above its rotation axis.

[0067] When the vehicle is going uphill, the front end of the header box 3 is relatively high. Under the action of gravity, the upper part of the partition 4 will swing toward the rear liquid inlet pipe 307, and the lower part will abut against the limit part 304 on the front side of the discharge pipe 301. At this time, the rear chamber 303 is connected to the discharge pipe 301. During the suction process of the water pump 5, water will enter the rear chamber 303 from the rear liquid inlet pipe 307, which is relatively low at this time, and then flow out from the discharge pipe 301 to the direction of the water pump 5. During the downhill process of the vehicle, the rear end of the header box 3 is relatively high. Under the action of gravity, the upper part of the partition 4 will swing toward the front liquid pipe 306, and the lower part will abut against the limit part 304 on the rear side of the discharge pipe 301. At this time, the front chamber 302 is connected to the discharge pipe 301. During the suction process of the water pump 5, water will enter the front chamber 302 from the front liquid pipe 306, which is relatively low at this time, and then flow out from the discharge pipe 301 to the direction of the water pump 5.

[0068] As another preferred embodiment, refer to Figure 4As shown, the first water outlet 2011 is connected to the rear chamber, the second water outlet 2012 is connected to the front chamber, and the center of gravity of the partition 4 is located at the lower side of its rotating shaft. Similarly, the partition 4 is in sliding contact with the inner wall of the collecting box 3, so that the two chambers do not interfere with each other. The chamber on the front side is the front chamber 302, and the chamber on the rear side is the rear chamber 303. The front chamber 302 is connected to the rear liquid inlet pipe 307, one end of the rear liquid inlet pipe 307 is connected to the front front side of the top of the collecting box 3, and the other end extends backward to connect to the second water outlet 2012. The rear chamber 303 is connected to the front liquid pipe 306, one end of the front liquid pipe 306 is connected to the rear side of the top of the collecting box 3, and the other end extends forward to connect to the first water outlet 2011. The inner wall of the collecting box 3 is tangent to both the front liquid pipe and the rear liquid inlet pipe, which can make the resistance smaller after the water enters the collecting box 3.

[0069] Furthermore, a limit portion 304 is provided in the collecting box 3 to limit the rotatable angle of the partition 4. The discharge pipe 301 is arranged in the middle of the bottom end of the collecting box 3, and the limit portion 304 is arranged at the bottom of the collecting box 3, formed by the concave side wall of the collecting box 3, and arranged on both sides of the discharge pipe 301. In this embodiment, the partition 4 is plate-shaped, with a rectangular cross-section at the upper part and a fan-shaped cross-section at the lower part. The lower part of the partition 4 is heavier, so its center of gravity is on the lower side of its own rotation axis, so that it can rotate under the influence of gravity when the collecting box 3 is tilted. Of course, in this embodiment, the partition 4 can also adopt other shapes, as long as it can ensure that its center of gravity is below its rotation axis.

[0070] When the vehicle is going uphill, the front end of the header box 3 is relatively high, and the lower part of the partition 4 will swing backward under the action of gravity, and abut against the limit part 304 on the rear side of the discharge pipe 301. At this time, the front chamber 302 is connected to the discharge pipe 301. During the suction process of the water pump 5, water will enter the front chamber 302 from the lower rear inlet pipe 307 at this time, and then flow out from the discharge pipe 301 to the direction of the water pump 5. When the vehicle is going downhill, the rear end of the header box 3 is relatively high, and the lower part of the partition 4 will swing forward under the action of gravity, and abut against the limit part 304 on the front side of the discharge pipe 301. At this time, the rear chamber 303 is connected to the discharge pipe 301. During the suction process of the water pump 5, water will enter the rear chamber 303 from the lower front inlet pipe 306 at this time, and then flow out from the discharge pipe 301 to the direction of the water pump 5.

[0071] For other functional structures of the vehicle, refer to Figure 1 , Figure 5 and Figure 6As shown, the vehicle of this embodiment includes a cleaning device 6 and a first flushing device 7. The cleaning device 6 is foldably arranged on the side of the vehicle body 1, and the first flushing device 7 is connected to the cleaning device 6 and connected to the water pump 5, and can flush the road surface in front of the cleaning device 6 when the cleaning device 6 is unfolded for cleaning. The cleaning device 6 is arranged on both sides of the middle part of the vehicle, and is used to clean the road surface. It has a rotatable sweeping disc, which can be raised and lowered and folded. When in use, it is unfolded and lowered to contact the road surface, and when not in use, it is raised and folded under the vehicle body 1. The first flushing device 7 is fixed to the cleaning device 6, and is supplied with water by the water pump 5. When the sweeping disc is unfolded, it is located in front of the sweeping disc, and can flush the road surface in front of the sweeping disc to improve the cleaning effect of the road surface. Specifically, the first flushing device 7 has a plurality of nozzles, and is arranged in an arc shape in front of the sweeping disc when it is in working state.

[0072] Secondly, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the vehicle includes a sewage suction device 8 and a second flushing device 9. The sewage suction device 8 is arranged at the rear end of the vehicle body 1, and includes a walking component 801 and a sewage suction pipe 802. The sewage suction pipe 802 is connected to the walking component 801 and can suck the dirt on the ground. The carriage 2 is also provided with a negative pressure box 202 for containing the dirt. The sewage suction pipe 802 is connected to the negative pressure box 202. The second flushing device 9 is connected to the water pump 5, and can flush the ground sucked by the sewage suction pipe 802. The sewage suction device 8 is arranged at the rear end of the vehicle body 1, so that the sucked dirt can be gathered at the rear end of the vehicle, which is convenient for the sewage to be discharged from the tail door of the carriage 2 later. At the same time, the rear space of the vehicle is large, which can also facilitate the staff to inspect and repair the sewage suction device 8. The walking component 801 walks on the road surface, and the inlet end of the sewage suction pipe 802 is fixed on the walking component 801, and the distance between the sewage suction pipe 802 and the road surface is maintained by the walking component 801, so that the sewage suction pipe 802 can always have a good sewage suction effect. The second flushing device 9 can flush the bottom surface again to increase the amount of water on the ground, making it easier for the sewage suction pipe 802 to suck away the dirt together with the sewage.

[0073] Regarding the specific structural form of the second flushing device 9, refer to Figure 5 and Figure 6As shown, the second flushing device 9 of this embodiment is also supplied with water by the water pump 5, and includes a first flushing pipe 901 and a second flushing pipe 902. The first flushing pipe 901 is horizontally arranged at the rear of the traveling assembly 801, perpendicular to the traveling direction of the vehicle, and is provided with a plurality of nozzles along its length direction, each nozzle facing the position directly opposite to the inlet end of the sewage suction pipe 802, to spray the road surface. There are two second flushing pipes 902, which are symmetrically arranged on both sides of the traveling device and located on both sides of the vehicle body 1. The second flushing pipe 902 can be folded and is provided with a plurality of nozzles at intervals along its own axial direction. After the second flushing pipe 902 is unfolded, the nozzles spray water to form an inclined water curtain on the road surface, which can concentrate the sewage and dirt on both sides of the vehicle to the sewage suction device 8 in the middle, so that the sewage suction pipe 802 can suck away the dirt and sewage.

[0074] In order to facilitate the emptying of the dirt in the negative pressure box 202, refer to Figure 2 , Figure 6 and Figure 7 As shown, the inner bottom wall of the negative pressure tank 202 is inclined, and the end close to the tailgate of the carriage 2 is lower. A third flushing device 13 is provided in the negative pressure tank 202, and the third flushing device 13 is provided with a plurality of cleaning nozzles 131, and the orientation of each cleaning nozzle 131 is at a different angle to the inner bottom wall. The dirt and sewage sucked into the negative pressure tank 202 by the suction pipe 802 will fall to the bottom of the negative pressure tank 202 due to gravity, and will be concentrated along the inner bottom wall of the negative pressure tank 202 toward the tailgate of the carriage 2, so as to facilitate the discharge of the dirt and sewage. Accordingly, part of the water tank 201 is arranged below the negative pressure tank 202, which is also convenient for the water in the water tank 201 to be discharged from the rear end of the carriage 2. The third flushing device 13 is provided with a plurality of cleaning nozzles 131, and each cleaning nozzle 131 has a different angle with the inner bottom wall, so that the inner wall of the negative pressure box 202 can be better flushed to remove dirt attached to the inner wall, so that the interior of the negative pressure box 202 is cleaner and more sanitary after the dirt and sewage are discharged.

[0075] Based on the purpose of optimizing the structure of the negative pressure box 202, refer to Figure 2 As shown, the outlet end of the sewage suction pipe 802 penetrates the negative pressure box 202 and extends upward. A protective plate 2021 is provided on the inner top wall of the negative pressure box 202, and the outlet end of the sewage suction pipe 802 faces the protective plate 2021. The dirt sucked by the sewage suction pipe 802 and sent into the negative pressure box 202 will fly out of the sewage suction pipe 802 due to inertia, then hit the protective plate 2021 and fall into the inner bottom of the negative pressure box 202. The protective plate 2021 can not only protect the negative pressure box 202 from the impact of the dirt, but also guide the dirt and sewage, so that the dirt and sewage fall quickly to the inner bottom of the negative pressure box 202.

[0076] Furthermore, in order to ensure the water quality of each water-using device, refer to Figure 1 and Figure 5As shown, at least two filters 10 are provided between the water pump 5 and the discharge pipe 301. The filtering accuracy of the filters 10 increases one by one along the water flow direction. After the water in the water tank 201 passes through several filters 10 with gradually increasing filtering accuracy, it can reach a relatively clean level, making each nozzle less likely to be blocked. In this embodiment, two filters 10 are provided and are sequentially arranged below the carriage 2.

[0077] For the waterway and negative pressure power source of the vehicle, refer to Figure 8 As shown, the vehicle includes a first engine, a transmission device 11 and a fan 12. The output end of the first engine is connected to the transmission device 11, and the transmission device 11 is connected to and drives the fan 12 and the water pump 5 to work. The suction port 121 of the fan 12 is connected to the negative pressure box 202. The first engine is arranged in the equipment box 203, and the output shaft of the first engine is connected to the shaft group 14, and the shaft group 14 is connected to the fan 12 and the water pump 5 through the transmission device 11, so that one first engine drives the fan 12 and the water pump 5 to work at the same time, thereby improving the utilization rate of the first engine. The vehicle of this embodiment, its power system is driven by the second engine, and the second engine is the engine used in conventional vehicles, which will not be repeated in this embodiment.

[0078] In addition, because the environment in the mine is relatively harsh and the requirements for vehicle use are high, the equipment on the vehicle of this embodiment all adopts mining explosion-proof equipment, which can effectively prevent the occurrence of dangerous situations such as electrical sparks and high temperatures, thereby greatly reducing the risk of explosion.

[0079] When the vehicle of this embodiment is going uphill, the water in the water tank 201 is concentrated at the second water outlet 2012, and when the vehicle is going downhill, the water in the water tank 201 flows to the first water outlet 2011, which greatly reduces the dead angle in the water tank 201. With the use of the water collecting tank 201 and the partition 4, the water pump 5 can normally pump out the water in the corner regardless of going uphill or downhill, thereby improving the utilization rate of the stored water by the vehicle and reducing the air from entering the water pump 5 from the discharge pipe 301. By providing the cleaning device 6, the first flushing device 7, the sewage suction device 8, the second flushing device 9, etc., the functionality of the vehicle is enriched, so that the vehicle can better clean the bottom surface of the well.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
