Description

Technical Field

[0001] The present invention relates to the technical field of coal mine equipment, and in particular to an automatic water pipe reel and water jet cutting equipment. Background Art

[0002] Ultra-high-pressure water jet equipment is a device that uses high-pressure water to cut coal gangue. Due to the high power of the high-pressure water pump and the large overall size of the equipment, it is greatly restricted in tunnel construction. In order to increase the working range of the equipment, the working device of the ultra-high-pressure water jet cutting equipment and the high-pressure water pump are connected through a high-pressure water pipe. Because the material of the high-pressure water pipe is relatively hard, if the water pipes are stacked together, the water pipes are easily damaged during the pulling process, causing safety hazards. Therefore, the water pipes need to be coiled up with a pipe reel mechanism. In the existing technology, the force of the pipe reeling mechanism for reeling and retracting the pipe is poorly adjustable, and the passive control has a lag. Therefore, a new pipe reel mechanism is needed that can automatically release the pipe as the working mechanism moves forward and automatically retract the pipe when retreating, thereby reducing the difficulty of operation for workers. Summary of the Invention

[0003] The present invention provides an automatic water hose reel and a water jet cutting device, so as to solve the problem in the prior art that the automatic water hose reel cannot be retracted or released in real time with the device.

[0004] In order to solve the above problems, according to one aspect of the present invention, there is provided an automatic hose reel for water pipes, comprising: a hose reel rotatably arranged to wind or release the water pipe; a driving unit drivingly connected to the hose reel, the driving unit having three modes, wherein when the driving unit is in a first mode, the driving unit drives the hose reel to rotate forward to wind the water pipe, when the driving unit is in a second mode, the driving unit drives the hose reel to rotate reversely to release the water pipe, and when the driving unit is in a third mode, the hose reel does not operate; a control assembly electrically connected to the driving unit to switch the mode of the driving unit, the control assembly having a first action zone, an intermediate zone, and a second action zone from bottom to top; wherein, when the water pipe moves to the first action zone, the water pipe triggers the control assembly to operate to switch the driving unit to the first mode, when the water pipe moves to the second action zone, the water pipe triggers the control assembly to operate to switch the driving unit to the second mode, and when the water pipe moves to the intermediate zone, the water pipe triggers the control assembly to operate to switch the driving unit to the third mode.

[0005] Furthermore, the control component includes an upper trigger switch and a lower trigger switch. When the water pipe moves to the first action area, the upper trigger switch is triggered, switching the drive unit to the first mode. When the water pipe moves to the second action area, the lower trigger switch is triggered, switching the drive unit to the second mode.

[0006] Furthermore, the control component also includes a first pull wire and a second pull wire, the lower end of the first pull wire is sleeved on the water pipe, and the upper end of the first pull wire is connected to the upper trigger switch, the upper end of the second pull wire is sleeved on the water pipe, and the lower end of the second pull wire is connected to the lower trigger switch; wherein, when the water pipe pulls the first pull wire in the first action area, the upper trigger switch is triggered, and when the water pipe pulls the second pull wire in the second action area, the lower trigger switch is triggered.

[0007] Furthermore, the driving unit includes a hydraulic motor, which drives the hose reel to rotate.

[0008] Furthermore, the drive unit also includes an electromagnetic reversing valve, which is used to control the rotation direction of the hydraulic motor to control the rotation direction of the hose reel; the upper trigger switch and the lower trigger switch are both electrically connected to the electromagnetic reversing valve to switch the working position of the electromagnetic reversing valve.

[0009] Furthermore, the driving unit further includes a bidirectional hydraulic lock. When the driving unit is in the third mode, the bidirectional hydraulic lock locks the position of the hydraulic motor to prevent the hydraulic motor from rotating.

[0010] Furthermore, the driving unit also includes a hydraulic pump and a hydraulic oil tank, and the hydraulic pump, the hydraulic oil tank and the hydraulic motor are all connected to provide power for the hydraulic motor.

[0011] Furthermore, the driving part also includes a transmission belt, a large transmission wheel and a small transmission wheel. The small transmission wheel is fixedly connected to the output shaft of the hydraulic motor, the large transmission wheel is fixedly connected to the hose reel, and the small transmission wheel drives the large transmission wheel to rotate through the transmission belt.

[0012] Furthermore, the automatic water hose reel also includes a bracket, and the hose reel, the driving part, and the control component are all arranged on the bracket.

[0013] According to another aspect of the present invention, a water jet cutting device is provided, which includes a working device and the above-mentioned automatic water pipe reel; wherein, when the working device moves away from the automatic water pipe reel, the working device pulls the water pipe wrapped around the reel upward, and the water pipe moves to the second action area; when the working device moves toward the automatic water pipe reel, the water pipe moves to the first action area under the action of gravity.

The control assembly has a first operating zone, an intermediate zone, and a second operating zone from bottom to top. When the water pipe moves to the first operating zone, the water pipe triggers the control assembly to switch the drive unit to the first mode; when the water pipe moves to the second operating zone, the water pipe triggers the control assembly to switch the drive unit to the second mode; and when the water pipe moves to the intermediate zone, the water pipe triggers the control assembly to switch the drive unit to the third mode. According to this solution, the control assembly responds to the position of the water pipe and controls the drive unit to change its operating mode. When a water pipe accumulates on the ground, it moves to the first operating zone, and the drive unit enters the first mode, driving the reel to rotate forward to wind and retract the pipe. When the pipe is stretched, it moves to the second operating zone, and the drive unit enters the second mode, driving the reel to rotate backward to release the wound pipe. When the pipe triggers the control component, the drive unit enters the third mode, and the reel does not operate. This configuration allows the automatic hose reel to automatically adjust its operating mode based on the position of the pipe, allowing it to retract or release the pipe in real time.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 3 As shown, an embodiment of the present invention provides an automatic hose reel for water pipes, comprising: a hose reel 10, rotatably arranged to wind or release a water pipe; a driving unit 20, drivingly connected to the hose reel 10, the driving unit 20 having three modes. When the driving unit 20 is in the first mode, the driving unit 20 drives the hose reel 10 to rotate forward to wind the water pipe; when the driving unit 20 is in the second mode, the driving unit 20 drives the hose reel 10 to rotate reversely to release the water pipe; when the driving unit 20 is in the third mode, the hose reel 10 does not operate; a control component 30, the control component 3 0 is electrically connected to the driving unit 20 to switch the mode of the driving unit 20. The control component 30 has a first action area, a middle area, and a second action area in the direction from bottom to top; wherein, when the water pipe moves to the first action area, the water pipe triggers the control component 30 to operate to switch the driving unit 20 to the first mode; when the water pipe moves to the second action area, the water pipe triggers the control component 30 to operate to switch the driving unit 20 to the second mode; when the water pipe moves to the middle area, the water pipe triggers the control component 30 to operate to switch the driving unit 20 to the third mode.

[0027] Adopting the scheme, the control assembly 30 reacts according to the position where the water pipe moves to, and controls the driving part 20 to change the working mode. When the water pipe has accumulation on the ground, the water pipe moves to the first action area, the driving part 20 is in the first mode, and the driving part 20 drives the pipe winding disc 10 to rotate forward to wind up the water pipe. When the water pipe is straight, the water pipe moves to the second action area, the driving part 20 is in the second mode, and the driving part 20 drives the pipe winding disc to rotate reversely to release the wound water pipe. When the water pipe cannot trigger the control assembly 30, the driving part 20 is in the third mode, and the pipe winding disc 10 does not act. In this way, the water pipe automatic winder can automatically adjust the working mode according to the position of the water pipe, and complete the winding up or releasing of the water pipe in real time. In use, the water pipe in the water pipe automatic winder is connected with the working device 50 (for example, a cutting water gun), and provides water source for the working device 50. When the working device 50 moves, the water pipe moves with the working device 50, so that the water pipe moves to the first action area, the intermediate area or the second action area.

[0028] As shown in Figure 1 , the control assembly 30 includes an upper trigger switch 31 and a lower trigger switch 32. When the water pipe moves to the first action area, the upper trigger switch 31 is triggered to switch the driving part 20 to the first mode. When the water pipe moves to the second action area, the lower trigger switch 32 is triggered to switch the driving part 20 to the second mode.

[0029] In this way, the action of the water pipe controls the upper trigger switch 31 and the lower trigger switch 32, so as to realize the switching of the mode of the driving part 20 through the movement of the water pipe.

[0030] In the embodiment one of the application, as shown in Figures 1 to 3 , the control assembly 30 further includes a first pull wire 33 and a second pull wire 34. The lower end of the first pull wire 33 is sleeved on the water pipe, and the upper end of the first pull wire 33 is connected with the upper trigger switch 31. The upper end of the second pull wire 34 is sleeved on the water pipe, and the lower end of the second pull wire 34 is connected with the lower trigger switch 32. When the water pipe pulls the first pull wire 33 in the first action area, the upper trigger switch 31 is triggered. When the water pipe pulls the second pull wire 34 in the second action area, the lower trigger switch 32 is triggered.

[0031] As shown in Figure 2 , when the water pipe is accumulated, the water pipe sleeved with the first pull wire 33 moves downward under the action of gravity at this time, the lower end of the first pull wire 33 is pulled by the water pipe, and the upper end of the first pull wire 33 triggers the upper trigger switch 31. As shown in Figure 3 , when the water pipe is straight, the upper end of the second pull wire 34 is pulled by the water pipe at this time, and the lower end of the second pull wire 34 triggers the lower trigger switch 32.

[0032] In actual application, using the first pull wire 33 and the second pull wire 34 to trigger the upper trigger switch 31 and the lower trigger switch is not the only optional solution of the present invention. A travel switch, a proximity switch, etc. can also be used as an alternative solution.

[0033] like Figure 1 As shown, the driving unit 20 includes a hydraulic motor 21, which drives the hose reel 10 to rotate. In this way, the hydraulic motor 21 is small in size, light in weight, and easy to automatically control, making it suitable as a driving device for the hose reel 10.

[0034] like Figure 1 As shown, the driving unit 20 also includes an electromagnetic reversing valve 22, which is used to control the rotation direction of the hydraulic motor 21 to control the rotation direction of the hose reel 10; the upper trigger switch 31 and the lower trigger switch 32 are both electrically connected to the electromagnetic reversing valve 22 to switch the working position of the electromagnetic reversing valve 22. Figure 2 As shown, when the upper trigger switch 31 is triggered, the electromagnetic reversing valve 22 is in the left position, and the hose reel 10 rotates forward; Figure 3 As shown, when the trigger switch 32 is triggered, the electromagnetic reversing valve 22 is in the right position, and the hose reel 10 rotates in the opposite direction. The electromagnetic reversing valve 22 is used to control the rotation direction of the hydraulic motor 21, which is convenient to control, simple in structure, and more adaptable to harsh working environments.

[0035] The drive unit 20 also includes a two-way hydraulic lock. When the drive unit 20 is in the third mode, the two-way hydraulic lock locks the hydraulic motor 21, preventing it from rotating. When the hose fails to trigger the control assembly 30, the two-way hydraulic lock locks the hydraulic motor 21, preventing the hose reel 10 from rotating. The two-way hydraulic lock ensures that the hose reel 10 remains stationary when it is not needed to retract or release the hose.

[0036] Furthermore, the driving unit 20 further includes a hydraulic pump and a hydraulic oil tank, which are connected to the hydraulic pump, the hydraulic oil tank and the hydraulic motor 21 to provide power to the hydraulic motor 21. The hydraulic pump pumps hydraulic oil into the hydraulic motor 21, thereby driving the hydraulic motor 21 to rotate.

[0037] like Figures 1 to 3 As shown, the driving part 20 also includes a transmission belt 23, a large transmission wheel 24 and a small transmission wheel 25. The small transmission wheel 25 is fixedly connected to the output shaft of the hydraulic motor 21, and the large transmission wheel 24 is fixedly connected to the hose reel 10. The small transmission wheel 25 drives the large transmission wheel 24 to rotate through the transmission belt 23.

[0038] The small transmission wheel 25 transmits the power of the hydraulic motor 21 to the large transmission wheel 24 through the transmission belt 23. The large transmission wheel 24 is fixedly connected to the hose reel 10, thereby driving the hose reel 10 to rotate.

[0039] Optionally, the large transmission wheel 24 and the small transmission wheel 25 may be sprockets, and the transmission belt 23 may be a transmission chain, so that power transmission between the hydraulic motor 21 and the hose reel 10 is achieved through chain transmission.

[0040] Optionally, the large transmission wheel 24 and the small transmission wheel 25 may be pulleys, and the transmission belt 23 may be a belt, so that power transmission between the hydraulic motor 21 and the hose reel 10 is achieved through belt transmission.

[0041] Optionally, the large transmission wheel 24 and the small transmission wheel 25 may be synchronous wheels, and the transmission belt 23 may be a synchronous belt. The synchronous belt transmission realizes power transmission between the hydraulic motor 21 and the hose reel 10 .

[0042] like Figures 1 to 3 As shown, the automatic hose reel further includes a bracket 40, on which the hose reel 10, the drive unit 20, and the control assembly 30 are all mounted. The bracket 40 protects the automatic hose reel. The hose reel 10 is rotatably mounted on the bracket 40.

[0043] According to another aspect of the present invention, a water jet cutting device is provided, which includes a working device 50 and the above-mentioned automatic water pipe reel; wherein, when the working device 50 moves away from the automatic water pipe reel, the working device 50 pulls upward the water pipe wrapped around the reel 10, and the water pipe moves to the second action area; when the working device 50 moves toward the automatic water pipe reel, the water pipe moves to the first action area under the action of gravity.
