Description

Technical Field

[0001] This utility model belongs to the field of waterjet cutting technology, specifically a waterjet cutting device for anchor removal vehicles. Background Technology

[0002] After mining operations are completed, the complete collapse method is generally used to treat the roof of the goaf. To prevent secondary accidents caused by large-scale roof overhang in the working face and to avoid excessive pressure during the collapse, it is necessary to remove anchor bolts and cables in a timely manner to allow the roof to collapse appropriately. Currently, water jet cutting is commonly used to remove anchor cables. Water jet cutting uses a high-pressure pump to pressurize water to extremely high pressure, and then forms a high-speed jet of water through a special nozzle. During this process, the energy of the water is highly concentrated when it passes through the nozzle, forming a fine water jet with extremely high cutting ability. However, existing anchor removal water jets spray a large amount of water during operation, which leads to a drastically worse working environment, affects the vision of workers, poses a high safety hazard, and the large amount of water can accelerate the collapse of the mine. Therefore, it is necessary to develop an anchor removal water jet cutting device to solve the shortcomings of the existing technology. Utility Model Content

A spring is provided between the connecting rod and the second connecting frame. The two ends of the spring are respectively connected to the second connecting frame and the connecting rod.

[0009] Preferably, the operating assembly includes an operating handle movably fitted inside the assembly cover. One end of the operating handle extends to the outside of the assembly cover and is integrally formed with an anti-slip head. The other end of the operating handle extends to the inside of the assembly cover and is fixedly connected to a connecting plate.

[0021] 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.

[0022] like Figures 1 to 5As shown, this utility model provides a waterjet cutting device for anchor removal vehicles, including two interlocking assembly covers 1. Each of the two assembly covers 1 has a coaxial through hole on its facing surface. A protective cover 4 is fixedly connected within the through hole. An operating component 3 is connected to the distal end of each of the two assembly covers 1. A connecting positioning component 2 is connected to the front of each of the two assembly covers 1. Under the connecting action of the connecting positioning component 2, the two assembly covers 1 swing relative to each other and fit tightly together. An anchor cable passes through the through hole of each of the two assembly covers 1. The protective cover 4 is tightly fitted onto the outer surface of the anchor cable. A waterjet nozzle 5 is fixedly fitted onto the side of one of the assembly covers 1, with one end of the waterjet nozzle 5 extending into the interior of the assembly cover 1. Located in the middle of the assembly cover 1, the extension line of the axis of the water jet nozzle 5 is perpendicular to the axis of the assembly cover 1. The other end of the water jet nozzle 5 extends to the outside of the assembly cover 1 and is fixedly connected to the water inlet pipe 6. A drainage component 7 is fixedly connected to the bottom of one of the assembly covers 1, and the drainage component 7 is tightly fitted to the bottom of the other assembly cover 1. Due to the setting of the connecting positioning component 2, the assembly cover 1 and the protective cover 4 can be stably wrapped around the surface of the anchor cable, so that the internal water flow is as low as possible from splashing to the outside. With the cooperation of the drainage component 7, the water after cutting can be guided and diverted, so that the water can be circulated, achieving the effect of environmental protection, while greatly reducing the difficulty of storing and transporting cutting water.

[0023] As shown in the figure and Figure 3 As shown, the protective cover 4 located in the bottom through hole of the assembly cover 1 is in the shape of an upward cone; due to the setting of the protective cover 4, the water sprayed by cutting can flow quickly to the drainage channel 73, avoiding the situation of seepage and outflow between the protective cover 4 and the anchor cable.

[0024] like Figure 2 and Figure 5 As shown, the connection positioning component 2 includes two first connecting frames 21 fixedly connected to the front of one of the assembly covers 1, and a second connecting frame 22 movably installed between the two first connecting frames 21. The back of the second connecting frame 22 is fixedly connected to the front of the other assembly cover 1. Due to the arrangement of the first connecting frame 21 and the second connecting frame 22, the two assembly covers 1 can be connected to each other.

[0025] like Figure 5 As shown, the second connecting frame 22 has two rotating shafts 23 inside, and the opposite sides of the two rotating shafts 23 are fixedly connected to the opposite surfaces of the two first connecting frames 21. Due to the setting of the rotating shafts 23, it is ensured that the first connecting frame 21 and the second connecting frame 22 can rotate stably along the same axis, so that the two assembly covers 1 can be stably flipped around the same axis and accurately fastened.

[0026] like Figure 5As shown, a connecting rod 24 is fixedly connected between the two rotating shafts 23. The outer diameter of the connecting rod 24 is smaller than that of the rotating shaft 23. A spring 25 is provided between the connecting rod 24 and the second connecting frame 22. The two ends of the spring 25 are connected to the second connecting frame 22 and the connecting rod 24, respectively. Due to the setting of the spring 25, with the cooperation of the connecting rod 24 and the rotating shaft 23, its elastic restoring force can drive the first connecting frame 21 and the second connecting frame 22 to rotate relative to each other, so that the two assembly covers 1 are tightly fastened together.

[0027] like Figures 2 to 4 As shown, the control assembly 3 includes a control handle 31 that is movably fitted inside the assembly cover 1. One end of the control handle 31 extends to the outside of the assembly cover 1 and is integrally formed with an anti-detachment head 32. The other end of the control handle 31 extends to the inside of the assembly cover 1 and is fixedly connected to a connecting plate 33. A plurality of evenly distributed guide anti-slip rollers 35 are movably embedded on the outer surface of the connecting plate 33 away from the control handle 31. The outer surface of the guide anti-slip rollers 35 rolls against the outer surface of the anchor cable. A limiting spring 34 is provided on the outer surface of the control handle 31, connecting the connecting plate 33 and the assembly cover 1. Due to the setting of the limiting spring 34, under the action of its elastic restoring force, the guide anti-slip rollers 35 can be pushed by the connecting plate 33, so that the guide anti-slip rollers 35 are tightly pressed against the surface of the anchor cable. This allows the control assembly 3 and the assembly cover 1 to rotate along the fixed water surface outside the anchor cable with the cooperation of the guide anti-slip rollers 35, and it is difficult to move along the outer axis of the anchor cable, thereby ensuring precise circumferential cutting.

[0028] like Figures 2 to 4 As shown, the drainage assembly 7 includes a flow guide 71 fixedly connected to the bottom of one of the assembly covers 1. The top of the flow guide 71 is tightly fitted to the bottom of the other assembly cover 1. The cross-section of the flow guide 71 is a slanted cone structure. The lower end of the flow guide 71 is connected to a drain pipe 72. The bottom of the assembly cover 1 is provided with a drain groove 73 connected to the top of the flow guide 71. Due to the setting of the flow guide 71, the water accumulated at the bottom of the inner cavity of the assembly cover 1 can be quickly flowed to the drain pipe 72 with the cooperation of the drain groove 73, preventing the water in the assembly cover 1 from accumulating too much and seeping to the outside, while avoiding affecting the cutting.

[0029] like Figure 1 and Figure 2 As shown, the height of the inner cavity of the assembly cover 1 is greater than the diameter of the water jet nozzle 5, and the cutting resistance of the assembly cover 1 is greater than that of the water jet nozzle 5. Because the assembly cover 1 has higher cutting resistance, it will not be damaged after the high-pressure water jet from the water jet nozzle cuts the anchor cable, thus ensuring the reuse of the equipment.

[0030] Working principle and usage process of this utility model:

[0031] The operator grips the two control handles 31 with both hands and pulls them apart to compress the limiting spring 34 under the constraint of the inner wall of the assembly cover 1. At the same time, pulling the two control handles 31 backward will open the back of the two assembly covers 1 with the help of the connecting positioning component 2. Then, the open structure of the back of the two assembly covers 1 is moved to the side of the anchor cable cutting end. Then, the two control handles 31 are released backward. Under the restoring force of the spring 25, the two assembly covers 1 move in opposite directions and lock tightly together. Under the restoring force of the guide anti-slip roller 35, the two connecting plates 33 move closer to each other and push the guide anti-slip roller 35 on their surface to press tightly against the anchor cable surface. Under the action of the upper and lower protective covers 4 on the facing surfaces of the two assembly covers 1, the anchor cable cutting surface is wrapped inside the assembly cover 1 and the protective cover 4. At this time, by rotating the two assembly covers 1 with the control handles 31, the guide anti-slip roller 35 can ensure that the assembly cover 1 rotates along the anchor cable fixed in the water surface and does not move in the direction along the anchor cable axis to change the cutting surface.

[0032] Then, turning on the pump will deliver water through the inlet pipe 6 to the water jet nozzle 5, so that the water jet nozzle 5 can cut the anchor cable inside the assembly cover 1. By rotating the assembly cover 1 by manipulating the handle 31, the water can be made to surround the anchor cable to complete the cutting. The cut water falls to the bottom of the inner cavity of the assembly cover 1 under the protection of the assembly cover 1 and the protective cover 4, and falls into the interior of the guide cover 71 through the drainage channel 73, and quickly gathers at the drainage pipe 72, and finally flows into the pump water source for circulation.
