Description

Technical Field

[0001] The invention relates to the technical field of water circulation systems, and in particular to a water circulation system for spraying water for a crawler type anchor removal unit for coal mines. Background Art

[0002] The crawler anchor withdrawal unit for coal mines is a component of the anchor withdrawal vehicle. The anchor withdrawal vehicle is designed for anchor withdrawal operations in the air intake tunnel, return air tunnel advance support section tunnel and other tunnels of the mining face. The anchor withdrawal vehicle has the characteristics of good underground passing performance, comprehensive functions, good safety, high work efficiency and low labor intensity for workers. In particular, when workers use this anchor withdrawal unit to perform anchor withdrawal operations, they can withdraw anchors by remote control by one person, avoiding shoulder-carrying and manual lifting, staying away from dangerous sources and avoiding safety accidents. Compared with traditional anchor withdrawal operations, the number of operators is reduced, achieving the goal of "reducing staff, increasing efficiency and ensuring safe production".

[0003] The anchor withdrawing vehicle is composed of seven major parts, namely, a traveling mechanism, a lifting mechanism, a cutting mechanism, a supporting mechanism, a hydraulic system, a cooling water spray system, and an electrical system. The traveling mechanism is used to drive the anchor withdrawing vehicle to move; the lifting mechanism is located at the front of the anchor withdrawing vehicle, and the cutting mechanism can be lifted up and down by the lifting cylinder and the connecting rod mechanism, and the cutting mechanism can reach the required working position by the rotation of the slewing support; the cutting mechanism is located at the front of the lifting mechanism of the anchor withdrawing vehicle, and the cutting mechanism can reach the working position by the coordinated rotation of two swing cylinders, and after aligning with the anchor to be cut, the tool is driven to move inward by the extension and retraction of the cylinder to achieve the purpose of cutting the anchor. The jacking mechanism is installed in the middle of the vehicle. When the anchor alignment operation is carried out, the handle of the operating valve is manipulated to extend the jacking cylinder to support the top plate, thereby increasing the stability of the vehicle during operation. The hydraulic system is used to provide working power. The function of the anchor withdrawal vehicle spray system is to provide spray water for the cutting mechanism of the anchor withdrawal vehicle. When the anchor withdrawal vehicle is working, it is connected to the water source in the tunnel through the water inlet and enters the nozzle of the cutting mechanism, which can reduce the local gas concentration and floating dust at the cutting site and reduce the sparks that may be generated during the cutting operation, thereby improving the safety of the cutting operation. The electrical system enables the vehicle to achieve long-distance remote control, achieving safety and efficiency, and reducing manpower and time.

[0004] Among the various components of the above-mentioned anchor unloading vehicle, the nozzles in the water spraying system are directly connected to the external water source, which makes the nozzles very easy to be blocked. At the same time, the water spraying angle of the water spraying system cannot be adjusted, and water cannot be sprayed in a targeted manner during work. In view of this, we propose a water circulation system for spraying water for a crawler anchor unloading unit for coal mines. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] Example:

[0025] A water circulation system for spraying water of crawler type anchor removal unit for coal mine, such as Figure 1-5 As shown, it should be noted that, in order to better understand the internal structure of the box, some boxes in the figure are not capped. In actual use, unless otherwise specified, the boxes are all sealed, including the anchor unwinding unit box 100. The anchor unwinding unit box 100 has a fuel tank assembly, a pump assembly, a wireless receiver installation assembly, a power failure instrument installation assembly and a power transmission box 101 inside. The outside of the anchor unwinding unit box 100 is also provided with a control button assembly assembly. Each component and box is used to control the work of the anchor unwinding vehicle. The power transmission box 101 is used to heat the water in the water storage tank 110 while transmitting power; A traveling mechanism is arranged below the anchor unwinding unit box 100. The traveling mechanism is driven by two hydraulic motors respectively. The sprocket is driven by the speed reduction mechanism to drive the crawler to realize walking. The crawler tensioning mechanism is composed of a tensioning wheel group and a tensioning cylinder. The tensioning wheel group can adjust the tension of the crawler through the telescopic movement of the tensioning cylinder. The crawler frame is fixed to both sides of the machine body by welding. A square groove is opened on the side of the crawler to facilitate the oil filling of the tensioning cylinder. The traveling speed reducer is connected to the crawler frame with high-strength bolts. A supporting mechanism is arranged above the anchor unwinding unit box 100. When the anchor is aligned, the handle of the operating valve is operated to extend the supporting cylinder to support the top plate, thereby increasing the stability of the vehicle during operation. It should be noted that the supporting mechanism and the walking action are interlocked. When the supporting operation is in progress, the walking action is locked and the walking operation cannot be performed. A travel switch is installed at the base. When the cylinder is retracted, the walking action can be unlocked. A lifting mechanism is also arranged in front of the anchor withdrawing vehicle. The cutting mechanism can be lifted up and down by the lifting oil cylinder and the connecting rod mechanism. At the same time, the cutting mechanism can be moved to the required working position by the rotation of the slewing support. The cutting mechanism is an important component of the anchor withdrawing vehicle for breaking anchors in the lane. The cutting mechanism can be moved to the working position by the coordinated rotation of the two swing cylinders. At the same time, after aligning with the anchor to be cut, the cutter is driven to move inward by the extension and contraction of the oil cylinder to achieve the purpose of cutting the anchor. A water tank 110 is arranged on the power transmission box 101. It is worth noting that when the anchor unwinding vehicle is working, the various components inside the power transmission box 101 are in operation, generating a large amount of heat to heat the water inside the water tank 110 and preliminarily soften the water. In addition, the water tank 110 is connected to an external water source. After softening, the water is transmitted to the nozzle mechanism 200 through the built-in pipes of the lifting mechanism and the cutting mechanism for spraying, which can reduce the local gas concentration and floating dust at the cutting location and reduce the sparks that may be generated during the cutting operation, thereby improving the safety of the cutting operation. Furthermore, a filter recovery box 120 is detachably mounted on the top of the water storage tank 110, and a partition baffle 121 is arranged in the middle of the filter recovery box 120 to divide the filter recovery box 120 into two areas, one area for collecting water and the other area for discharging water. Both sides of the area where the filter recovery box 120 discharges water are interconnected with the water storage tank 110 and are fixedly connected with a triangular stand 122. It is worth noting that the shape of the triangular stand 122 is convenient for water to pass over, while sediment and debris are not easy to pass over the triangular stand 122, thereby filtering the water and preventing dust in the mine tunnel from entering the water storage tank 110; a square channel is processed at the bottom of the partition baffle 121, and the partition baffle 1 21 is provided with evenly distributed circular channels in the middle and lower part. A precipitant or activated carbon is placed inside the filter recovery box 120. The preferred precipitant is polyacrylamide, which is used in wastewater treatment and mineral processing and helps to aggregate and precipitate suspended particles. It should be noted that the square channel at the bottom of the partition baffle 121 is located between the two triangular platforms 122. The square channel and the circular channel facilitate the exchange of water in the two areas. At the same time, their size can prevent some large impurities from entering the drainage area from the collection area. The box cover above the collection area of ​​the filter recovery box 120 can be opened, so that the staff can gather the sprayed water and pour it into the collection area of ​​the filter recovery box 120. Furthermore, a ball valve 102 is fixedly connected to one side of the bottom of the water storage tank 110, a softening treatment box 130 is fixedly connected to one side of the ball valve 102, a limit baffle 133 is fixedly connected to the middle of the softening treatment box 130 to separate the softening treatment box 130 into two areas, one area is used for softening water, and the other area is used to adjust the Ph of the softening component 140, the bottom of the softening water area of ​​the softening treatment box 130 is stepped, the top of the softening treatment box 130 is fixedly connected to an electric guide rail 131, the top of the slider of the electric guide rail 131 is fixedly connected to a first electric push rod 132, and the first The output end of the electric push rod 132 is fixedly connected to a softening component 140, and the softening component 140 includes two grille connecting plates 141 connected by hinges. A plurality of ion exchange resin layers 142 are arranged inside the grille connecting plates 141. It is worth noting that the upper grille connecting plate 141 is connected to the output end of the first electric push rod 132, and the bottom of the lower grille connecting plate 141 is processed with an arc edge. It can be understood that the upper grille connecting plate 141 is a fixed angle, and the lower grille connecting plate 141 can rotate around the hinge, and the rotation direction can only be toward one side of the hinge. The softening component 140 can be folded. In order to adjust the Ph of the ion exchange resin layer 142 in the Ph adjustment area, the softening component 140 is located on one side of the step when it is in the softening water area of ​​the softening treatment box 130, so that the water flow is ejected from 103 and all enters the ion exchange resin layer 142 in the softening component 140 for ion exchange, that is, the ion exchange resin layer 142 absorbs the calcium and magnesium ions in the water flow; a Ph sensor 134 is fixedly connected to the middle position of the bottom of the Ph adjustment area of ​​the softening treatment box 130, and an arc guide rod 135 is fixedly connected to the side away from the limit baffle 133. Yes, the Ph sensor 134 detects the high-concentration sodium chloride solution in the Ph adjustment area of ​​the softening treatment box 130. When it performs ion exchange with the ion exchange resin layer 142, that is, the calcium and magnesium ions absorbed by the ion exchange resin layer 142 are exchanged with sodium ions, the Ph value of the solution changes. After the Ph sensor 134 detects it, it continues to add sodium chloride solution to increase the concentration of sodium ions. The arc-shaped guide rod 135 cooperates with the arc-shaped edge at the bottom of the grid connecting plate 141 at the lower middle of the softening component 140 so that the softening component 140 is forced to fold under the push of the first electric push rod 132; like Figure 6-10 As shown, it also includes a nozzle mechanism 200 disposed on the anchor splitter, which is used to spray the softened water at an angle; Furthermore, the nozzle mechanism 200 includes a frustum-shaped nozzle 210 mounted on the atomizer and an adjustment column 220 located in the center of the atomizer; the top of the frustum-shaped nozzle 210 is fixedly connected to the outer wall of the adjustment column 220, and a plurality of water spray holes 213 distributed in a circular pattern are processed on the frustum-shaped nozzle 210. It is worth noting that, if Fig.11As shown, the opening angles of the water spray holes 213 located on the same horizontal plane are the same, the opening angle of the top water spray hole 213 is perpendicular to the horizontal line, and the opening angle of the bottom water spray hole 213 is perpendicular to the inclined surface of the frustum-type nozzle 210. The opening angles of the water spray holes 213 between the two change with the number of water spray holes 213. From the cross-section, the angle relationship between the extension line of the water spray hole 213 opening and the inclined surface of the frustum-type nozzle 210 is as follows: ∠n=90°+(ns)θ / (s-1); Wherein, n represents the sequence number of holes from top to bottom, counted from the cross section; s represents the total number of holes on the cross section; θ represents the angle between the inclined surface of the frustum-type nozzle 210 and the horizontal plane; the preferred total number of holes on the cross section of this embodiment is 3, and the angle between the inclined surface of the frustum-type nozzle 210 and the horizontal plane is 30°, at which time ∠1=60°, ∠2=75°, and ∠3=90°; it should be noted that the opening angle of the water spray hole 213 changes from top to bottom, and the water mist sprayed at the top is closer to the operation center, which is used to cool the working equipment and reduce the occurrence of sparks. The water mist sprayed at the bottom is away from the operation center and sprayed to the surroundings to expand the spraying range, thereby better reducing the concentration of gas in the air; Furthermore, a separate frame 211 is fixedly connected to both sides of the frustum-shaped nozzle 210, and a cylindrical activated carbon 212 is placed inside the separate frame 211. It is worth noting that the cylindrical activated carbon 212 can absorb methane, the main component of gas, so as to further reduce the concentration of gas in the air and prevent explosion accidents caused by high gas concentration during construction. At the same time, the new cylindrical activated carbon 212 can be replaced to ensure the continuous progress of the construction work and improve work efficiency. Furthermore, the adjusting column 220 is processed with evenly distributed through holes around it, and specifically, the number of the through holes is consistent with the number of the water spray holes 213; a load-bearing cavity rod 230 is fixedly connected to the through holes of the adjusting column 220, and a movable guide link 232, a transmission link 233 and a moving link 234 are respectively arranged inside the load-bearing cavity rod 230, the guide link 232 is located at the front part of the load-bearing cavity rod 230, the transmission link 233 is located in the middle position of the load-bearing cavity rod 230, and the moving link 234 is located at the rear part of the load-bearing cavity rod 230, the tail end of the guide link 232 is connected to the transmission link 233 through a rotating shaft, and the tail end of the transmission link 233 is connected to the moving link 234 through a rotating shaft. Rod 234, it is worth noting that the moving link 234 is a driving source, which is transmitted through the transmission link 233 to cause the guide link 232 to move inside the bearing cavity rod 230, the front end of the guide link 232 is fixedly connected with a rubber plug 231, the guide link 232 points to the corresponding water spray hole 213, and the rear end of the moving link 234 is connected with an arc-shaped limit block 235 through a spring. It should be noted that when the guide link 232 moves toward the outside of the bearing cavity rod 230, the rubber plug 231 blocks the corresponding water spray hole 213, and when the guide link 232 moves toward the inside of the bearing cavity rod 230, there is a gap between the rubber plug 231 and the corresponding water spray hole 213, that is, a water spray outlet; At the same time, the outer wall of the top end of the adjusting cylinder 220 is fixedly connected to the second electric push rod 221, and the output end of the second electric push rod 221 is fixedly connected to the limiting cylinder 222. A plurality of arc grooves are processed on the limiting cylinder 222. The arc grooves on the adjusting cylinder 220 fit with the arc limit blocks 235. Specifically, the number of arc grooves on the limiting cylinder 222 is the same as the above-mentioned s. At the same time, the limiting cylinder 222 places the arc limit blocks 235 in their arc grooves from bottom to top in the process of moving downward, and at least one arc limit block 235 is located in the arc groove of the limiting cylinder 222. It should be noted that in the initial state, the arc limit block 235 is in the limit Under the extrusion of the outer wall of the limiting cylinder 222, the compression spring is located inside the moving link 234. At this time, the guide link 232 is located outside the bearing cavity rod 230. The rubber plug 231 and the corresponding water spray hole 213 are tightly fitted to form a seal. When the corresponding arc groove on the limiting cylinder 222 moves to the current horizontal plane, the arc limit block 235 moves toward the outside of the moving link 234 under the action of the spring, and the moving link 234 also moves with it. After the transmission of the transmission link 233, the guide link 232 moves toward the inside of the bearing cavity rod 230. At this time, the rubber plug 231 is separated from the water spray hole 213, so that there is a gap between the two, which is convenient for spraying water. In this embodiment, first, the staff first connects the external water source to the water tank 110 through a pipeline, adds water to the water tank 110, and the anchor unloading vehicle sets out towards the working position. Due to the operation of the machine, the power transmission box 101 generates a large amount of heat to heat the water inside the water tank 110, so that the water inside the water tank 110 precipitates water alkali, and the water is initially softened. Then, the water is discharged to the softening treatment box 130 through the ball valve 102. At this time, the slider of the electric guide rail 131 places the softening component 140 on the step of the softening water area of ​​the softening treatment box 130, and the discharged water flows through the ion exchange resin layer 142. At this time, the remaining calcium and magnesium ions in the water flow are exchanged with the sodium ions in the ion exchange resin layer 142, and the water is further softened. The softened water is cooled in the softening water area of ​​the softening treatment box 130 and then transmitted to the nozzle mechanism 200; After the softening treatment, the first electric push rod 132 first pulls up the first electric push rod 132 so that the bottom height is higher than the height of the limit baffle 133, and then the slider of the electric guide rail 131 drives the softening component 140 to move to the top of the arc guide rod 135, and then the first electric push rod 132 drives the softening component 140 to move downward. During the movement, the lower grille connecting plate 141 first contacts the arc guide rod 135, and the lower grille connecting plate 141 rotates through the cooperation of its arc edge and the arc guide rod 135, and finally folds in the Ph adjustment area of ​​the softening treatment box 130. There is a high concentration of sodium chloride solution in this area. The sodium ions in the solution are exchanged with the calcium and magnesium ions absorbed in the ion exchange resin layer 142 again, so that the ion exchange resin layer 142 restores the function of softening water. The increase of calcium and magnesium ions in the solution causes the Ph of the solution to change. After detecting the change, the Ph sensor 134 sends an electrical signal to the terminal to remind the staff to replace the solution in time; Before spraying, the arc-shaped limit blocks 235 are squeezed by the outer wall of the limit cylinder 222 and are located inside the moving connecting rod 234. The guide connecting rod 232 is located outside the bearing cavity rod 230 and the rubber plugging head 231 is tightly fitted with the corresponding water spray hole 213. During spraying, the second electric push rod 221 drives the limit cylinder 222 to move, and the arc groove on the limit cylinder 222 moves to the horizontal plane of the corresponding arc-shaped limit block 235. At this time, the spring in the moving connecting rod 234 drives the arc-shaped limit block 235 to move toward the arc groove, and the moving connecting rod 234 also moves therewith, and under the transmission of the transmission connecting rod 233, the guide connecting rod 232 moves toward the inside of the bearing cavity rod 230. At this time, the rubber plugging head 231 is separated from the tight fit with the water spray hole 213, and the water flow is sprayed out from the corresponding water spray hole 213. At the same time, the spraying range of the spray can be adjusted as needed to improve the practicality of the device; When recycling water, the staff can place the collection bucket on the anchor unwinding vehicle in advance, and the water mist will fall into the collection bucket after spraying, or the staff can collect the water in the tunnel and add the collected water to the water collection area of ​​the filter recovery box 120. The water flows to the water discharge area through the square holes and circular holes on the partition baffle 121, and when a lot of water is collected, it overflows the triangular table 122 and flows into the water storage tank 110 for water recycling. At the same time, the precipitant or activated carbon inside the filter recovery box 120 can precipitate and purify the circulating water to prevent impurities from falling into the water storage tank 110.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
