Pipeline dredging device

Technical Field

The application relates to the field of pipeline dredging equipment, in particular to a pipeline dredging device.

Background

The cause of the pipe blockage is very complex and can be generally divided into the following two cases: firstly, the fluid substances in the pipeline are slowly adhered to the wall of the pipeline for years to gradually taper the pipeline, or the pipeline and other substances undergo chemical reaction to gradually taper, so that the slow pipeline is blocked; and secondly, the blockage caused by foreign matters falling in. The current pipeline dredger is manually driven, or driven by various electricity, gas or liquid, and the public pipeline is generally driven by gas or liquid, so that the damage of electric leakage to human bodies is avoided. The pipeline dredger of either type is equipped with a dredging pipe, the front end of which is equipped with a drill bit.

Among the prior art, the operating personnel generally uses the dredging machine to clear up, and it includes the frame, is fixed with motor and spool on the frame, and the winding has the flexible axle on the spool, and the one end of flexible axle is fixed with the mediation head, in the clearance in-process, is connected flexible axle and motor to insert the mediation head in the pipeline, the flexible axle gives the mediation head with the power transmission of motor, and the mediation head is rotatory to dredge in the pipeline.

The conventional dredging head is usually a drill bit, and can be rotated to extend into dirt to drill and dredge the blocked dirt, but cannot clean the inner wall of a pipeline, so that more dirt still adheres to the inner wall of the pipeline, and the blockage is easily caused again in a short time.

Detailed Description

The technical scheme of the application is further described in detail below with reference to the accompanying drawings.

The embodiment of the application discloses a pipeline dredging device. Referring to fig. 1 to 3, a pipeline dredging device includes a main machine 1, a flexible shaft 2 connected to the main machine 1, and a dredging head 3 disposed at an end of the flexible shaft 2.

The main machine 1 is used for outputting rotating force to the flexible shaft 2, and the dredging head 3 is coaxially and fixedly connected to the end part of the flexible shaft 2 and is used for synchronously rotating along with the flexible shaft 2. The outside of flexible axle 2 is provided with hose 21, and hose 21 rotates with flexible axle 2 to make the handheld hose 21 of staff, in order to stretch into the pipeline that waits to dredge with dredging head 3, dredging head 3 follows the rotation of hose 21 and rotates, in order to clear up the inner wall of pipeline.

The dredging head 3 comprises a shaft body 31 fixedly connected to the end portion of the flexible shaft 2, a drill bit portion 32 fixedly arranged at the end portion of the shaft body 31, and a scraping portion 33 arranged on the shaft body 31.

Specifically, the bit portion 32 includes a socket 41 fixedly connected to an end of the shaft body 31 and an arc plate 42 provided on the socket 41, the arc plate 42 being provided in plurality and circumferentially arranged outside the socket 41.

The outer side edge of the arc plate 42 is arc-shaped, so that after the drill bit 32 extends into the pipeline, the damage to the inner wall of the pipeline caused by the sharp end of the arc plate 42 can be reduced, the end of the arc plate 42 is inserted into the blockage, and the arc plate 42 is driven to rotate along with the rotation of the shaft body 31, so that the blockage can be loosened until the blockage is dredged.

The outer side of the arc plate 42 is provided with saw teeth 43. When the arc plate 42 rotates, the friction force between the saw teeth 43 and the blocking object can be improved, and sliding between the blocking object and the arc plate 42 is prevented, so that the pipeline can be efficiently dredged.

Further, the scraping portion 33 includes two chains 51 and a counterweight 52 provided on the chains 51, one end of the chains 51 is fixedly provided on the socket 41, a sleeve 53 is provided on the shaft body 31, and the other end of the chains 51 is provided on the sleeve 53.

The shaft body 31 rotates to drive the chain 51 to rotate, and the counterweight 52 drives the chain 51 to spread and rub against the inner wall of the pipeline so as to scrape off the plugs such as the sludge adhered to the inner wall of the pipeline.

The shaft body 31 is provided with a plurality of equally spaced positioning holes 61, the sleeve 53 is provided with lock holes (not shown) penetrating through the side wall of the sleeve 53, and lock rods 62 are arranged in the lock holes and the positioning holes 61 in a penetrating manner; one end of the chain 51 is fixedly provided on the sleeve 53.

The adjusting sleeve 53 is close to the sleeve head 41, so that the maximum distance of the two chains 51 after being unfolded in opposite directions is increased, and the large-caliber pipeline can be dredged and cleaned; after the sleeve 53 is adjusted to principle the sleeve head 41, the maximum distance of the two chains 51 after being unfolded in opposite directions can be reduced, so that the small-caliber pipeline can be dredged and cleaned, and the practicability is high. After the lock hole on the sleeve 53 is overlapped with the positioning hole 61 on the shaft body 31, the lock rod 62 is inserted, so that the sleeve 53 can be fixed on the shaft body 31.

The further technical scheme is that one side surface of the counterweight 52, which faces away from the shaft body 31, is an arc surface, and because the chain 51 is connected to two end parts of the counterweight 52, when the flexible chain 51 drives the counterweight 52 to start rotating, the two end parts of the counterweight 52 can not strictly follow the chain 51 and synchronously rotate; the arrangement of the cambered surface on the outer side surface can prevent the sharp end of the counterweight 52 from colliding with the inner wall of the pipeline in the rotation process of the chain 51, so that the damage to the pipeline is reduced.

It should be noted that, in the present utility model, unless explicitly specified and limited otherwise, the terms "connected," "disposed," and the like are to be construed broadly, and for example, "disposed" may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
