Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, in particular to mining equipment oil pipe cleaning equipment. Background Art

[0002] Usually, the oil pipes of mining equipment are hydraulic hoses (generally made of high-pressure steel wire braided or wire wound hoses buckled by special equipment), which are mainly used for hydraulic power transmission or transportation of high-pressure media such as water, gas, and oil at working temperatures of -40℃ to 100℃ to ensure the circulation of liquids and the transmission of liquid energy. Hydraulic hoses are usually reel-type when leaving the factory, with a length of hundreds of meters. In actual situations, they need to be cut into multiple shorter hydraulic hoses. However, after the hydraulic hoses are cut, debris and oil stains usually stick to the inner wall of the hydraulic hoses, so a cleaning process is usually required.

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

[0021] like Figures 1 to 5 As shown, an embodiment of the present invention provides a mining equipment oil pipe cleaning device, including a base 1, which is generally a steel structure or a wooden structure and mainly plays the role of stable placement.

[0022] A cleaning mechanism is movably arranged on the base 1 ; specifically, the cleaning mechanism includes a medium driving device 2 , a medium pipeline 3 , a spray gun 4 and a trigger assembly 5 .

[0023] The medium driving device 2 is generally a gas pump or a liquid pump. The medium driving device 2 is fixedly arranged on the base 1. One end of the medium pipeline 3 is sealed and connected to the output end of the medium driving device 2. The other end of the medium pipeline 3 is sealed and connected to the air inlet end of the spray gun 4. The medium pipeline 3 is generally a soft rubber hose. The air outlet end of the spray gun 4 forms a cleaning end 8. The trigger component 5 is arranged in the spray gun 4. The trigger component 5 is used to isolate the spray gun 4 when the spray gun 4 is loaded with materials, and to connect the spray gun 4 when the loading of the spray gun 4 is completed.

[0024] The present application mainly fills a sponge disc 29 in a spray gun 4, and then provides a medium driving force through a medium driving device 2, so that the medium sprays the sponge disc 29 in the spray gun 4 out to a high degree through a medium pipe 3. The sponge disc 29 is compressed in the cavity 9 of the spray gun 4 and enters the oil pipe. Since the diameter of the sponge disc 29 is slightly larger than the inner diameter of the oil pipe, the sponge disc 29 moves at a high speed along the oil pipe under the action of the medium, and then the compressed sponge disc 29 rubs against the inner wall of the oil pipe to achieve cleaning. When the medium is air, the sponge disc 29 adheres to stains by dry wiping, and when the medium is a cleaning liquid, the sponge disc 29 can be used for cooperative cleaning.

[0025] In the present invention, a slide groove 6 is provided on the base 1, and a first mounting bracket 7 is slidably provided at one end of the slide groove 6. The spray gun 4 is sleeved on the top of the first mounting bracket 7, and the bottom of the first mounting bracket 7 is configured to be a protrusion that is slidably engaged with the slide groove 6. In this way, the position of the spray gun 4 can be adjusted. The slidably engaged protrusion can be provided with a screw or the like, and the first mounting bracket 7 is locked by squeezing the slide groove 6.

[0026] In the present invention, the cleaning end 8 includes a gas flow direction along the cavity 9 of the spray gun 4, and the corresponding end of the spray gun 4 is fixedly connected with an inner embedded section 81 and a guide section 82 with a hollow inner cavity, and a conical cavity 28 for compressing the sponge disc 29 is provided at the connection between the cavity 9 of the spray gun 4 and the inner embedded section 81, wherein the guide section 82 is conical, so that the guide section 82 can be slightly smaller than the inner diameter of the oil pipe, which is convenient for manual insertion, and then the maximum inner diameter of the inner embedded section 81 is slightly larger than or exactly equal to the inner diameter of the oil pipe, which is convenient for sealing, and the inner diameter of the conical cavity 28 is equal to the original diameter of the sponge disc 29, and then after the compression of the conical cavity 28, the inner hollow channels of the inner embedded section 81 and the guide section 82 are smaller than the inner diameter of the oil pipe, so that the compressed sponge disc 29 can smoothly enter the hollow channel inside the oil pipe.

[0027] In the present invention, a second mounting bracket 10 is slidably provided at the other end of the slide groove 6, and a docking sleeve 11 is sleeved on the top end of the second mounting bracket 10. One end of the docking sleeve 11 is used to be sealed and nested in the other end of the oil pipe. A rotatable mounting groove 12 is provided at the other end of the docking sleeve 11, and an indicating impeller 13 is rotatably installed in the rotatable mounting groove 12. In the present invention, a second mounting bracket 10 is also provided at the other end of the base 1. The docking sleeve 11 provided in the second mounting bracket 10 has a structure that is substantially the same as that of the cleaning end 8 of the spray gun 4. The purpose of providing the docking sleeve 11 is to fix the oil pipe from both ends, and to straighten the oil pipe by sliding adjustment between the two to prevent the sponge disc 29 from being blocked in the oil pipe due to the bending of the oil pipe. In the process of the sponge disc 29 moving from one end of the oil pipe to the other end, the sponge disc 29 may no longer be able to enter the docking sleeve 11 due to the attenuation of the medium pressure, and thus stops at the front end of the docking sleeve 11. The sponge disc 29 can be taken out by removing the connection between the oil pipe and the docking sleeve 11, thereby playing a role in collecting discarded sponge discs 29.

[0028] Furthermore, when the oil pipe is blocked, directly using the sponge disc 29 for cleaning may cause it to be completely blocked. In this case, the sponge disc 29 can be placed on the spray gun 4 without placing it, and air can be directly injected into the oil pipe. If the oil pipe is not blocked, the air can pass through the oil pipe normally and be sprayed out from the right end of the docking sleeve 11, so that the gas will drive the indicator impeller 13 to rotate. On the other hand, the loss of gas or sponge disc 29 through the oil pipe can be estimated according to the rotation speed of the indicator impeller 13, and the power of the air pump can be adjusted.

[0029] In the present invention, the spray gun 4 is provided with a vertical through groove, and the trigger assembly 5 includes a sliding sealing plate 14 slidably arranged in the vertical through groove, and a sliding sleeve 15 for sealingly sleeve the top of the sliding sealing plate 14 is provided at the top of the vertical through groove, and a limiting bracket 16 is provided at the top of the sliding sleeve 15, and a sliding limiting rod 17 is connected to the top of the sliding sealing plate 14, and a sliding hole for slidingly nesting the sliding limiting rod 17 is opened on the limiting bracket 16, and a reset spring 18 is sleeved on the area between the top of the sliding hole and the top of the sliding sealing plate 14 on the sliding limiting rod 17.

[0030] The sliding sealing plate 14 is a plate-shaped structure, the length of which is at least greater than the diameter of two cavities 9. A channel hole 141 is provided at the bottom of the sliding sealing plate 14. Due to the setting of the vertical through groove, the sliding sealing plate 14 slides vertically until the channel hole 141 of the sliding sealing plate 14 faces the cavity 9 of the spray gun 4, that is, the channel hole 141 coincides with the cavity 9, so that the sponge disc 29 can enter the cavity 9 through the channel hole 141. When the sliding sealing plate 14 slides down until the channel hole 141 completely escapes from the cavity 9, the top of the sliding sealing plate 14 can just block the cavity 9, and the sliding sleeve 15 ensures the stability of sliding.

[0031] In the present invention, a feeding trough 19 is opened on the spray gun 4 in the area between the medium pipeline 3 and the sliding sealing plate 14, a sealing plate 20 for closing the feeding trough 19 is slidably installed on the spray gun 4, and a telescopic cylinder 22 is fixedly installed on the spray gun 4 through a mounting plate 21, and the free end of the telescopic cylinder 22 is fixedly connected to the sealing plate 20.

[0032] Multiple locking mechanisms are used to lock the two ends of the oil pipe at the corresponding ends of the cleaning end 8 and the docking sleeve 11 respectively; the locking mechanism includes a third mounting bracket 23 slidably mounted in the slide groove 6, and a mounting ring 24 is provided at the top of the third mounting bracket 23. Two telescopic rods 26 are symmetrically mounted on the mounting ring 24 through a cylinder bracket 25, and the free ends of the telescopic rods 26 are fixedly connected to arc-shaped pressure plates 27.

[0033] Working principle: One end of the oil pipe is manually or mechanically sleeved on the inner embedded section 81 through the guide section 82, and then the two arc-shaped pressure plates 27 are closed by the extension and retraction of the telescopic rod 26, thereby locking the oil pipe, and then the telescopic cylinder 22 is opened to allow the sealing plate 20 to slide and leak out of the feeding trough 19, and then the sponge disc 29 is put into the feeding trough 19, and then the sealing plate 20 is used to close the feeding trough 19 by the telescopic cylinder 22, and then the medium driving device 2 is opened. The medium driving device 2 increases the air pressure in the medium pipeline 3 and the air pressure on the left side of the sliding sealing plate 14, and then the sliding sealing plate 14 is driven to slide up quickly by a structure such as a manual or telescopic cylinder, and the channel hole 141 of the sliding sealing plate 14 is connected to the cavity 9, and the high air pressure quickly squeezes out the sponge disc 29, so that the sponge disc 29 is thrown out from the other end of the oil pipe.

[0034] Of course, the other end of the oil pipe can also be sleeved on the docking sleeve 11 before the above operation, and the fixing method is similar to the above operation to perform a ventilation test.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. 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 replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
