Description

Technical Field

[0001] The utility model relates to the technical field of pre-buried wire pipes, in particular to a pre-buried wire pipe dredging device. Background Art

[0002] Pre-buried pipes are pipes that are pre-buried in construction projects for subsequent structural and process construction. In building structures, there are generally few pipelines that are openly laid. In general cast-in-place structures, the electrical conduit is fixed to the formwork and steel bars when tying the steel bars, and the pipes are in the structural components after the concrete is poured. Pre-buried pipes, as the name suggests, are buried before pouring concrete to facilitate subsequent wiring.

[0003] In the utility model patent with announcement number CN209608232U, a device for clearing and threading electrical pre-buried wire pipes is proposed, comprising a base, legs are arranged at the bottom of the base, casters are arranged at the bottom of the legs, an air compressor is fixedly arranged on the top of the base, the air compressor is connected to a high-pressure container through an air inlet pipe, a first chamber and a second chamber are arranged in the high-pressure container...; as the air compressor runs, the air flow can be sent to the first flow limiting pipe and the second flow limiting pipe through the air inlet pipe, and the valve is gradually opened. At this time, the air flow enters the second chamber through the first flow limiting pipe, and enters the inside of the clearing head along the air outlet pipe. Finally, the air flow is ejected from the air hole, and the clearing head is pushed to drag the air outlet pipe to move to the deep of the wire pipe, from the end of the wire pipe to the end of the pipe, to complete the clearing of the pre-buried electrical wire pipe.

[0004] However, in the above patent, the unclogging head is pushed to move in the wire pipe only by the gas ejected from the air hole, but the driving force of this type of unclogging head movement is limited. When the wire pipe is blocked, it cannot maintain a strong driving effect, and its unclogging effect is poor. In view of this, the present application proposes a pre-buried wire pipe unclogging device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a pre-buried wire pipe unclogging device, which has the effect of pushing the unclogging head to move inside the wire pipe body through the operation of an air compressor. At the same time, due to the inclined setting of the air outlet pipe, the unclogging head can be rotated while it moves, so as to maintain a strong pushing effect on the unclogging head and improve the unclogging efficiency. This solves the problem that the pre-buried wire pipe unclogging device in the prior art cannot maintain a strong pushing effect on the unclogging head when the wire pipe is blocked, resulting in a poor unclogging effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pre-buried wire pipe dredging device, comprising a mobile base, a protection box fixedly installed on the top of the mobile base, an air guide pipe movably installed in the protection box, and a wire pipe body, wherein a rotating dredging mechanism is arranged inside the protection box, and an auxiliary component is arranged outside the air guide pipe;

[0008] The outer sliding sleeve of the air guide tube is provided with a blocking block which fits tightly with one end of the wire tube body, the interior of the unblocking head is provided with a rotating propulsion component, the outer side of the unblocking head is movably connected with a plurality of cleaning plates, and the interior of the unblocking head is provided with an adjustment component for adjusting the position of the cleaning plate.

[0009] Furthermore, the rotary propulsion assembly includes an air storage chamber opened inside the unclogging head, and the air guide pipe extends into the air storage chamber. The right side of the unclogging head is fixedly connected with an air outlet pipe extending to the air storage chamber, and the air outlet pipe is arranged at an angle. There are multiple air outlet pipes, and the air outlet pipes are arranged in a ring shape on the outside of the air guide pipe.

[0010] Furthermore, a universal wheel is fixedly connected to the bottom of the mobile base, a pushing frame is fixedly connected to the top of the mobile base, a rocker is rotatably connected to the front of the protective box, and the rocker is fixedly connected to the winding roller.

[0011] Furthermore, the blocking block is in a frustum shape, and a rubber pad is fixedly connected to one side of the blocking block close to the wire tube body.

[0012] Furthermore, the adjustment component includes a fixed rod fixedly connected inside the unblocking head, an electric push rod fixedly connected inside the unblocking head, an output end of the electric push rod fixedly connected to a movable block slidably adapted to the fixed rod, and a connecting rod hinged to the movable block and the unblocking head is fixedly connected to one side of the cleaning plate close to the fixed rod, and the connecting rods on the left and right sides are symmetrically arranged.

[0013] Furthermore, a rotating sleeve is hinged on the left side of the cleaning plate, and a telescopic rod hinged to the end of the dredging head is slidably connected inside the rotating sleeve.

[0017] 1. The pre-buried wire pipe dredging device, through the provided rotating dredging mechanism, can cooperate with the provided blocking block to form a closed space in the part of the wire pipe body located on the left side of the dredging head when the wire pipe body is blocked. When the air compressor is running, the air guide pipe can increase the air pressure in the closed space, thereby facilitating the movement of the dredging head in the wire pipe body. At the same time, due to the inclined setting of the air outlet pipe, the gas in the air storage cavity will be discharged in a cyclone manner, thereby facilitating the rotation of the dredging head while the dredging head moves, thereby playing a role similar to that of a drill bit, maintaining a strong pushing effect, and improving the dredging efficiency.

[0018] 2.

[0027] Among them, the inside of the protective box 2 is fixedly connected to a high-pressure container 4 which is fixedly connected to the output end of the air compressor 3, and the output end of the high-pressure container 4 and the air guide pipe 6 both extend into the winding roller 5, so that the gas in the high-pressure container 4 can flow to the air guide pipe 6. The other end of the air guide pipe 6 is fixedly connected to a clearing head 7 which extends to the wire pipe body 8.

[0028] In this embodiment, the outer sliding sleeve of the air guide tube 6 is provided with a blocking block 17 which fits tightly with one end of the wire tube body 8. The blocking block 17 is in a cone shape. A rubber pad is fixedly connected to the side of the blocking block 17 close to the wire tube body 8. The blocking block 17 is conveniently used to form an enclosed space in the part of the wire tube body 8 located on the left side of the clearing head 7, thereby facilitating the movement of the clearing head 7 as the air pressure in the space increases.

[0034] It should be noted that the pre-buried wire pipe clearing device, through the auxiliary components set up, can rotate the threaded rod 19 to adjust the position of the support plate 20, so as to facilitate the use of the support plate 20 to fit closely with the wire pipe body 8 and maintain the firm installation of the blocking block 17, so as to maintain the sealing effect of the port of the wire pipe body 8.

[0035] The working principle of the above embodiment is:

[0036] When using the pre-buried wire pipe dredging device, the user can hold the push frame and cooperate with the universal wheel to push the movable base 1 to move it to the desired position, and then place the dredging head 7 in the wire pipe body 8, and install the blocking block 17 to keep the sealing effect of the port of the wire pipe body 8. In this process, the electric push rod 10 can be operated to adjust the position of the movable block 11, so that the connecting rod 13 can adjust the distance from the cleaning plate 12 to the fixed rod 9 with the movement of the movable block 11, so as to facilitate the cleaning plate 12 to fit the inner wall of the wire pipe body 8;

[0037] After that, the air compressor 3 can be operated, and the high-pressure container 4 can be cooperated to make the air guide pipe 6 move towards the air storage chamber 701 in the unclogging head 7.
