Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to a cleaning device for a communication channel opening pipe segment. Background Art

[0002] During the shield construction of the connecting channel, the tunnel is assembled from prefabricated segments. However, during the assembly process, there will be more or less debris on the surface of the segments, and when leakage occurs at the tail of the shield, the sprayed slurry will also condense on the surface of the segments. Therefore, a cleaning device is generally installed at the tail of the shield machine to clean the impurities on the surface of the segments by spraying.

[0003] However, as far as the existing cleaning device for pipe segments is concerned, the spray height and position of the spray rod cannot be adjusted, and the connecting channel is generally a circular hole.

[0034] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment 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.

[0035] Please refer to Figures 1 to 10 As shown:

[0036] Embodiment 1: The present invention provides a cleaning device for a communication channel opening segment, comprising a mounting assembly 1, wherein the mounting assembly 1 comprises a fixed seat 101, a rotating seat 102 and a driving motor 103, wherein the fixed seat 101 is fixedly mounted on a vehicle body, and the rotating seat 102 is rotatably connected to a side surface of the fixed seat 101, and the driving motor 103 is fixedly mounted on a side surface of the fixed seat 101; further comprising a cleaning assembly and an adjusting mechanism 4, wherein the cleaning assembly is composed of a telescopic mechanism 2 and a synchronization mechanism 3;

[0037] The telescopic mechanism 2 includes an active spray rod 201 and a plurality of driven spray rods 202, and the active spray rod 201 and the driven spray rod 202 are inserted into the rotating seat 102 in a ring array, and the plurality of driven spray rods 202 are symmetrically arranged on both sides of the active spray rod 201, and the synchronization mechanism 3 includes a synchronization gear a301, a synchronization gear b302 and a connecting gear 303, the synchronization gear a301 and the synchronization gear b302 are both rotatably connected to the inside of the rotating seat 102, and the synchronization gear a301 and the synchronization gear b302 are symmetrically arranged, the connecting gear 303 is rotatably connected to the inside of the rotating seat 102, and the gear teeth on both sides of the connecting gear 303 are respectively meshed with the gear teeth of the synchronization gear a301 and the synchronization gear b302 for transmission;

[0038] The adjusting mechanism 4 includes a control shaft 401, a locking gear 402, an adjusting gear 403 and a positioning rod 404. The control shaft 401 is inserted into the interior of the rotating seat 102, and the locking gear 402 is rotatably connected to the exterior of the control shaft 401. The adjusting gear 403 is rotatably connected to the interior of the rotating seat 102, and the positioning rod 404 is rotatably connected to the exterior of the rotating seat 102. The adjusting gear 403 and the positioning rod 404 are connected via gear transmission, and the rotating shaft of the driving motor 103 and the control shaft 401 are connected via transmission.

[0039] The electric push rod 5 is fixedly installed inside the rotating seat 102, and one end of the push rod of the electric push rod 5 is rotatably connected to the side of the control shaft 401. In use, the adjustment mechanism 4 has two usage modes. One is the cleaning mode. In this mode, when the driving motor 103 rotates, it can drive the rotating seat 102 to rotate, thereby driving the cleaning nozzle 6 to follow the rotation to achieve the cleaning operation of the inner wall of the pipe segment. The other is the adjustment mode. In this mode, the driving motor 103 can change the use position of the telescopic mechanism 2 when rotating, so that it can be adapted for cleaning with holes of different inner diameters. The distance between the cleaning nozzle 6 and the inner wall of the pipe segment is always fixed, with high cleaning efficiency and good effect. The two usage modes can be regulated and switched through the telescopic state of the electric push rod 5, which is flexible to use and quick and convenient to switch.

[0040] In the embodiment of the present disclosure, the rotating seat 102, the control shaft 401, the locking gear 402 and the adjusting gear 403 are all on the same rotating axis. In use, when the electric push rod 5 is in a retracted state, the adjusting mechanism 4 is in a cleaning mode. In this mode, when the driving motor 103 rotates, it can drive the control shaft 401 to rotate synchronously. Since the locking gear 402 is only inserted into the interior of the integral tooth groove 1011 of the rotating seat 102 at this time, the locking gear 402 will not hinder and lock the rotation of the rotating seat 102 at this time, and the clutch gear 4012 is in a state of being out of the interior of the adjusting tooth groove 4031, so that when the control shaft 401 rotates, it will not drive the adjusting gear 403 to rotate, and at this time the cleaning gear 4011 is inserted into the rotating tooth groove 10 21, so that the control shaft 401 can drive the rotating seat 102 to rotate when it rotates, the side of the rotating seat 102 is connected to the liquid supply device through a rotating joint, and the liquid supply device can supply liquid to the inside of the active spray rod 201 and the driven spray rod 202 through the rotating seat 102, and the top of the active spray rod 201 and the driven spray rod 202 are fixedly installed with a cleaning nozzle 6, and a group of synchronization mechanisms 3 are provided between the active spray rod 201 and the driven spray rod 202 and between adjacent driven spray rods 202. The liquid supply device can supply cleaning liquid to the inside of the telescopic mechanism 2, and finally spray it out for cleaning use through the cleaning nozzle 6, so that the cleaning nozzle 6 can clean the pipe segment inside the hole when following the rotation of the rotating seat 102, which is easy to use and cleans thoroughly.

[0041] In the embodiment of the present disclosure, an integral tooth groove 1011 is provided inside the opposite side of the fixed seat 101 and the rotating seat 102. When the electric push rod 5 is in the retracted state, the locking gear 402 is only inserted into the integral tooth groove 1011 of the rotating seat 102. A cleaning gear 4011 is provided outside the control shaft 401, and a rotating tooth groove 1021 is provided inside the rotating seat 102. When the electric push rod 5 is in the retracted state, the cleaning gear 4011 is inserted into the rotating tooth groove 1021, and the adjusting gear 403 is provided inside. The adjusting tooth groove 4031 is provided with a clutch gear 4012 at one end of the control shaft 401. When the electric push rod 5 is in a retracted state, the clutch gear 4012 escapes from the inside of the adjusting tooth groove 4031. In use, when the electric push rod 5 is in an extended state, the adjusting mechanism 4 is in an adjustment mode. In this mode, the locking control gear 402 is simultaneously inserted into the inside of the integral tooth groove 1011 of the fixed seat 101 and the rotating seat 102, so that the rotating seat 102 and the fixed seat 101 form a whole, that is, the rotating seat 102 cannot rotate. At this time, the cleaning gear 4011 will be out of the rotating tooth groove 1021, so that the rotating seat 102 will not hinder and lock the rotation of the control shaft 401. The clutch gear 4012 will be inserted into the adjusting tooth groove 4031 after the electric push rod 5 is extended. Therefore, when the driving motor 103 drives the control shaft 401 to rotate, the control shaft 401 can drive the adjusting gear 403 to rotate. When the adjusting gear 403 rotates, it can drive the positioning rod 404 to rotate through the gear. The outer part of the top rod body of the positioning rod 404 is provided with a thread. The positioning rod 404 is screwed to the side of the active spray rod 201 through the rod body thread. When the positioning rod 404 rotates, it can drive the active spray rod 201 to move in the radial direction of the rotating seat 102 to change the use position through the rod body thread. Under the action of the synchronization mechanism 3, the driven spray rod 202 and the active spray rod 201 can move synchronously to change the use position, thereby changing the rotation radius of the cleaning nozzle 6 following the rotating seat 102, and can adapt to the cleaning operation of the internal pipe segments of holes of different sizes, specifications, and inner diameters. It is easy to adjust and flexible to use.

[0042] In the embodiment of the present disclosure, the side of the active spray rod 201 and the driven spray rod 202 are both provided with an active rack 2011, the side of the synchronous gear a301 is provided with an active gear 3011, the gear teeth of the active rack 2011 and the active gear 3011 are meshed for transmission, the other side of the driven spray rod 202 is also provided with a driven rack 2021, and the side of the synchronous gear b302 is provided with a driven gear 3021, the driven rack 2021 and the driven gear 3021 are meshed for transmission, in use, when the active spray rod 201 moves inside the rotating seat 102, the active rack 2011 on its side can be driven by the active gear The wheel 3011 drives the synchronous gear a301 to rotate. When the synchronous gear a301 rotates, it can drive the synchronous gear b302 to rotate through the connecting gear 303. When the synchronous gear b302 rotates, the driven gear 3021 can drive the driven spray rod 202 to move synchronously through the driven rack 2021, and adjacent driven spray rods 202 can also move synchronously under the action of the synchronous mechanism 3. The regulation is convenient and fast. Since the telescopic mechanism 2 is arranged in a circular array on the rotating seat 102, the telescopic mechanism 2 changes the rotation radius of the cleaning nozzle 6 following the rotating seat 102 after changing the use position, and the use is stable.

[0043] Specific usage and function of this embodiment: In the present invention, the adjustment mechanism 4 has two usage modes, one of which is a cleaning mode. In this mode, when the driving motor 103 rotates, it can drive the rotating seat 102 to rotate, thereby driving the cleaning nozzle 6 to follow the rotation to achieve the cleaning operation on the inner wall of the pipe segment. The second is an adjustment mode. In this mode, the driving motor 103 can change the use position of the telescopic mechanism 2 when rotating, so that it can be adapted for cleaning of holes with different inner diameters. The distance between the cleaning nozzle 6 and the inner wall of the pipe segment is always fixed, and the cleaning efficiency is high and the effect is good. The two usage modes can be regulated and switched by the telescopic state of the electric push rod 5. When the electric push rod 5 is in a retracted state, the adjustment mechanism 4 is in a cleaning mode. In this mode, when the driving motor 103 rotates, it can The control shaft 401 can be driven to rotate synchronously. Since the locking gear 402 is only inserted into the integral tooth groove 1011 of the rotating seat 102 at this time, the locking gear 402 will not hinder and lock the rotation of the rotating seat 102 at this time, and the clutch gear 4012 is in a state of being out of the adjusting tooth groove 4031. Therefore, when the control shaft 401 rotates, it will not drive the adjusting gear 403 to rotate. At this time, the cleaning gear 4011 is inserted into the rotating tooth groove 1021, so that the control shaft 401 can drive the rotating seat 102 to rotate when it rotates, and the liquid supply device can supply the cleaning liquid to the inside of the telescopic mechanism 2, and finally spray it out for cleaning through the cleaning nozzle 6, so that the cleaning nozzle 6 can surround the hole when following the rotation of the rotating seat 102. The cleaning operation is performed on the pipe segments at the bottom. When the electric push rod 5 is in the extended state, the adjusting mechanism 4 is in the adjusting mode. In this mode, the locking gear 402 is simultaneously inserted into the integral tooth grooves 1011 of the fixed seat 101 and the rotating seat 102, so that the rotating seat 102 and the fixed seat 101 form a whole, that is, the rotating seat 102 cannot rotate, and at this time the cleaning gear 4011 will slip out of the rotating tooth groove 1021, so that the rotating seat 102 will not hinder and lock the rotation of the control shaft 401. The clutch gear 4012 will be inserted into the adjusting tooth groove 4031 after the electric push rod 5 is extended, so that when the driving motor 103 drives the control shaft 401 to rotate, the control shaft 401 can drive the adjusting gear 403 to rotate, and the adjusting gear 403 is When rotating, the positioning rod 404 can be driven to rotate by the gear. When rotating, the positioning rod 404 can drive the active spray rod 201 to move in the radial direction of the rotating seat 102 to change the use position through the rod body thread. Under the action of the synchronization mechanism 3, the driven spray rod 202 and the active spray rod 201 can be synchronously moved to change the use position, thereby changing the rotation radius of the cleaning nozzle 6 following the rotating seat 102, and can adapt to the cleaning operation of the internal pipe segments of the holes of different sizes, specifications, and inner diameters. When the active spray rod 201 moves inside the rotating seat 102, the active rack 2011 on its side can drive the synchronous gear a301 to rotate through the active gear 3011. When the synchronous gear a301 rotates, it can drive the synchronous gear b302 to rotate through the connecting gear 303.When the synchronous gear b302 rotates, the driven gear 3021 can drive the driven spray rod 202 to move synchronously through the driven rack 2021, and the adjacent driven spray rods 202 can also move synchronously under the action of the synchronous mechanism 3, which is convenient and fast to adjust. Since the telescopic mechanism 2 is arranged in a circular array on the rotating seat 102, the telescopic mechanism 2 changes the rotation radius of the cleaning nozzle 6 following the rotating seat 102 after changing the use position.
