Description

Technical Field

[0001] This utility model relates to the field of tunnel cleaning technology, and in particular to a cleaning device. Background Technology

[0002] The air compressor cleaning method uses compressed air to draw out the mud containing drill cuttings to clean the hole. Compressed air is delivered into the mud discharge pipe through the air duct, so that the mud and air are mixed with a low density mud and air. Under the pressure of the liquid column outside the pipe, the mud and the sediment at the bottom of the hole are discharged outward along the mud discharge pipe. At the same time, water is injected into the hole by a water pump to keep the water level constant until clear water is sprayed out or the thickness of the sediment reaches the design requirements.

[0003] According to Chinese Patent Publication No. CN222010158U, a hole cleaning device for tunnel construction is disclosed. It is equipped with a booster, a turbo fan, a scraper, etc. The turbo fan in the booster is driven by a motor to generate a strong airflow, which causes the reaction force of the jet pipe to blow out the mud and slag. At the same time, the suction pipe generates a strong suction force to suck the mud and slag in the hole into the dust collection box, thus completing the mud and slag collection operation in the hole. This simplifies the work steps, makes it convenient for workers to operate, reduces the workload of workers, and improves the hole cleaning efficiency.

[0004] However, the fixed length of the jet pipe in this technical solution makes it difficult to effectively clean holes that exceed the length of the jet pipe. This requires personnel to replace the jet pipe and reassemble it, which affects the working efficiency of the device and makes it inconvenient for personnel to use. Therefore, we propose a hole cleaning device for tunnel construction. Utility Model Content

[0005] The purpose of this invention is to provide a hole cleaning device to alleviate the technical problem of low work efficiency caused by the need for frequent nozzle replacement in existing hole cleaning devices.

[0006] The present invention provides a hole cleaning device, comprising: a hole cleaning device body and a telescopic tube, wherein the length of the telescopic tube is adjustable, and one end of the telescopic tube is connected to the output end of the hole cleaning device body.

[0007] Furthermore, the telescopic tube includes a first jet pipe and a second jet pipe. A sleeve is fitted on the outer wall of the first jet pipe and the second jet pipe. The first jet pipe and the second jet pipe are slidably connected to the sleeve. Fixing components are provided at both ends of the sleeve and between the first jet pipe and the second jet pipe, respectively. After the fixing components are locked, the first jet pipe and the second jet pipe are fixed relative to the sleeve.

[0008] Furthermore, both the first and second jet pipes are fixedly fitted with arched ring plates on their outer walls, and the inner wall of the sleeve is provided with an annular groove, in which the arched ring plates are engaged.

[0009] Furthermore, a pad is fixedly installed on the outer wall of the arched ring plate, and the pad is in close contact with the inner wall surface of the ring groove.

[0010] Furthermore, the fixing component includes a fixing ring and a pin. The fixing ring is fixedly installed at one end of the sleeve. A groove is formed on the outer wall of the fixing ring. A pin groove is formed on the outer wall of both the first and second air jet pipes. The pin moves through the inner wall of the groove and is inserted into the pin groove. A pull ring is fixedly installed at one end of the pin. A spring is surrounded on the outer wall of the pin. The spring is fixedly installed between the inner wall of the groove and the inner side of the pull ring.

[0011] Furthermore, a limiting slide plate is fixedly installed on the outer wall of both the first jet pipe and the second jet pipe, and a limiting groove is formed on the inner wall of the sleeve, with the limiting slide plate and the limiting groove being slidably connected.

[0012] Furthermore, the number of arched ring plates on both the first jet pipe and the second jet pipe is at least two;

[0013] And / or, the arched ring plate is made of elastic steel sheet, and the pad is made of wear-resistant rubber.

[0014] Furthermore, both the first and second jet pipes have at least two pin slots, and the pin rods are adapted to the pin slots.

[0015] Furthermore, a support block is installed on the main body of the hole cleaning device;

[0016] The main body of the hole cleaning device is equipped with a lifting drive mechanism, and the drive end of the lifting drive mechanism is connected to a traveling structure so that the support block or the traveling structure contacts the ground.

[0017] Furthermore, the lifting drive mechanism includes a fixed plate, which is fixed to the outer wall of the main body of the hole cleaning device. An electric cylinder is fixedly installed at the top of the fixed plate, and a base plate is fixedly installed at the output end of the electric cylinder.

[0018] The traveling structure includes casters, which are fixedly installed at the bottom of the base plate, and the electric cylinder is used to drive the base plate to move.

[0020] The hole cleaning device provided by this utility model includes: a hole cleaning device body and a telescopic tube, the length of which is adjustable, and one end of which is connected to the output end of the hole cleaning device body.

[0021] By setting an adjustable telescopic tube, repeated disassembly of the spray pipe is avoided.

[0036] The hole cleaning device provided by this utility model can be used for cleaning tunnels.

[0037] like Figure 1 - Figure 6 As shown, the hole cleaning device provided by this utility model may include a hole cleaning device body 1 and a telescopic tube with adjustable length. The hole cleaning device body 1 is the technology disclosed in the patent with publication number CN222010158U, entitled "A Hole Cleaning Device for Tunnel Construction," therefore its internal structure is not described or drawn in this document or in the accompanying drawings.

[0038] The telescopic tube includes a jet pipe 2 and a jet pipe 3. One end of the jet pipe 2 is connected to the output end of the main body 1 of the cleaning device. A sleeve 4 is fitted on the outer wall of the jet pipe 2 and the jet pipe 3. The airflow generated by the main body 1 of the cleaning device passes through the jet pipe 2, the sleeve 4 and the jet pipe 3 in sequence before being ejected. Both the jet pipe 2 and the jet pipe 3 are slidably connected to the sleeve 4, so that the length of the part of the jet pipe 2 and the jet pipe 3 exposed outside the sleeve 4 is adjustable.

[0039] To further improve sealing and prevent air leakage, arched annular plates 5 are fixedly fitted onto the outer walls of both jet pipe 2 and jet pipe 3. Annular grooves 7 are formed on the inner wall of the sleeve 4, and the arched annular plates 5 are engaged within these grooves. A pad 6 is fixedly installed on the outer wall of the arched annular plates 5, and the pad 6 fits tightly against the inner surface of the annular groove 7 to reduce gaps between them. Taking jet pipe 2 as an example, when jet pipe 2 is pulled out, the arched annular plate 5 will leave one annular groove 7 and then enter another. The distance between two adjacent annular grooves 7 can be set to a fixed value, making it convenient for the user to identify the current extension length.

[0040] A fixing assembly 10 is provided at both ends of the sleeve 4 between the first jet pipe 2 and the second jet pipe 3, respectively. The fixing assembly 10 includes a fixing ring 1001 and a pin 1004. The fixing ring 1001 is fixedly installed at one end of the sleeve 4. A groove 1002 is formed on the outer wall of the fixing ring 1001. A pin groove 1006 is formed on the outer wall of both the first jet pipe 2 and the second jet pipe 3. The pin 1004 moves through the inner wall of the groove 1002, and one end of the pin 1004 is inserted into the pin groove 1006. A pull ring 1003 is fixedly installed at the other end of the pin 1004. A spring 1005 surrounds the outer wall of the pin 1004. The spring 1005 is fixedly installed between the inner wall of the groove 1002 and the inner side of the pull ring 1003. The spring 1005 pulls the pull ring 1003, so that the pull ring 1003 tends to move closer to the fixing ring 1001.

[0041] When using the hole-cleaning device, the pull ring 1003 on one end of the fixing component 10 of the sleeve 4 can be pulled outward, causing the pull ring 1003 to stretch the spring 1005. This causes the pull ring 1003 to drive the pin 1004 to retract into the groove 1002, disengaging the pin 1004 from the pin slot 1006 at its current position. Then, the sleeve 4 can be moved outward, extending it and increasing the length of the jet pipe 2. When the sleeve 4 reaches its maximum movement distance, the pull ring 1003 on the other end of the fixing component 10 of the sleeve 4 can be pulled outward, removing the pin 1004 from limiting the jet pipe 3. Then, the jet pipe 3 can be pulled outward, increasing its extension length and further extending the length of the jet pipe 2 and the sleeve 4. The overall length of the air jet pipe 2 and the sleeve 4 and the air jet pipe 3 can be easily adjusted by personnel through the above structure, so that the main body of the hole cleaning device 1 can clean holes of different depths, reduce the limitations of the device's use, and solve the problem that in the existing technical solution, the length of the air jet pipe is fixed, making it difficult to effectively clean holes that exceed the length of the air jet pipe. This would require personnel to replace the air jet pipe and reassemble it, thus affecting the working efficiency of the device and making it inconvenient for personnel to use. In addition, the arched ring plate 5, the pad 6 and the ring groove 7 can improve the sealing between the sleeve 4 and the air jet pipe 2 and the air jet pipe 3, avoiding gas leakage and affecting the working efficiency of the main body of the hole cleaning device 1.

[0042] Both jet pipe 2 and jet pipe 3 have fixedly installed limiting slide plates 8 on their outer walls, and the inner wall of the sleeve 4 has a limiting groove 9 that extends along the length of the telescopic pipe. The limiting slide plate 8 and the limiting groove 9 are slidably connected. By setting the limiting slide plate 8 and the limiting groove 9, the sleeve 4 can be limited, improving the stability of the sleeve 4 during use and reducing tilting and shaking.

[0043] The number of arched ring plates 5 on both jet pipe 1 2 and jet pipe 2 3 is several, and the material of the arched ring plate 5 can be elastic steel sheet, and the material of the pad 6 can be wear-resistant rubber.

[0044] By setting the pad 6, gaps can be reduced and the sealing between the arched ring plate 5 and the ring groove 7 can be increased.

[0045] Both jet pipe 2 and jet pipe 3 have multiple pin grooves 1006 to lock them in place after a certain length is exposed. A pin 1004 is fitted into the pin groove 1006. By providing the pin 1004, it can be inserted into the pin groove 1006, thereby limiting and fixing the sleeve 4 and jet pipe 3.

[0046] A support block 17 is installed on the main body 1 of the hole cleaning device; a lifting drive mechanism is installed on the main body 1 of the hole cleaning device, and the drive end of the lifting drive mechanism is connected to a traveling structure so that the support block 17 or the traveling structure contacts the ground.

[0047] The bottom of the main body 1 of the hole cleaning device is fixedly installed with a support block 17, and the number of support blocks 17 can be four.

[0048] A fixing plate 11 is fixedly installed on the outer wall of the main body 1 of the hole cleaning device. The fixing plate 11 can be set on opposite sides of the main body 1 of the hole cleaning device. An electric cylinder 12 is fixedly installed on the top of the fixing plate 11. A base plate 13 is fixedly installed on the output end of the electric cylinder 12. A caster wheel 14 is fixedly installed on the bottom end of the base plate 13. The electric cylinder 12 drives the base plate 13 to move vertically.

[0049] When it is necessary to move the main body 1 of the hole cleaning device, the electric cylinder 12 can be activated. The electric cylinder 12 drives the base plate 13 to move downward. The base plate 13 drives the casters 14 to contact the ground, and finally pushes the support block 17 off the ground. At this time, personnel can directly push the main body 1 of the hole cleaning device to move, which makes it convenient for personnel to move the main body 1 of the hole cleaning device, saves manpower, and is highly practical.

[0050] A limiting rod 15 is fixedly installed at the top of the base plate 13. A rod hole 16 is provided on the fixing plate 11, and the limiting rod 15 moves through the rod hole 16. By setting the limiting rod 15, the base plate 13 can be limited, thereby improving the stability of the base plate 13 during use.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
