Description

Tool for butting corrugated pipes

Technical Field

The utility model relates to a pipeline interfacing apparatus, especially a frock for bellows butt joint.

Background

In the outdoor drainage pipeline construction process, the corrugated pipe is usually sealed by a socket sealing rubber ring. Generally, a sealing rubber ring is sleeved in the spigot, a lubricant is coated on the surface of the sealing rubber ring on the working surface in the socket, and the installed pipe is manually inserted into the socket by aligning with the center line of the socket. This kind of socket joint mode, to the pipeline that the diameter is less than 300mm, adopt manpower socket joint comparatively light. A pipeline with the diameter of 300mm weighs about 35KG, and for the pipeline with the diameter of more than 300mm, the weight is heavier, and the socket joint of the pipeline is difficult to complete by manpower and common tools. The problems of time and labor waste, slow construction progress, poor splicing effect, easy corrugated pipe damage and delayed construction period in the process of splicing pipelines with the diameter of more than 300mm exist.

Disclosure of Invention

The utility model discloses a solve the technical problem who exists among the well-known technique and provide a frock that can improve bellows butt joint efficiency and butt joint quality.

The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: the utility model provides a frock for bellows butt joint, includes that two are controlled distribution and the semicircle hoop of card put in the bellows recess, one of them is to move the hoop, and another is quiet hoop, move the hoop with all be equipped with a rack between two tip of quiet hoop, quiet hoop with the rack rigid coupling, move the hoop pass through the slider with rack connection, the slider with move the hoop rigid coupling, with rack sliding connection the supporting has the ratchet on the slider, the ratchet with rack toothing, the pivot of ratchet with the rack is perpendicular the cooperation has the pawl on the ratchet, the pawl rotates to be connected on the spanner, the spanner pass through the connecting rod with the pivot of ratchet is connected, the connecting rod with the pivot of ratchet rotates to be connected, with the spanner rigid coupling, the spanner adopts door type structure, and the rigid coupling is two between the connecting rod.

The utility model has the advantages and positive effects that: through adopting ratchet pawl structure to drive and move the hoop, utilize one section bellows that moves the hoop pulling butt joint, utilize quiet hoop to stabilize one section bellows, and then make two sections bellows realize coaxial butt joints, easy operation is convenient, labour saving and time saving, the butt joint degree of accuracy and efficiency are compared and are all promoted by a wide margin in the manual work, can realize the accurate butt joint of bellows, thoroughly stop the emergence of bellows damage phenomenon, can the reduction of erection time, simultaneously the utility model discloses still have simple structure, convenient operation and cost-effective advantage.

Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:

referring to fig. 1, a tooling for corrugated pipe butt joint comprises two semicircular hoops which are distributed left and right and clamped in a corrugated pipe groove, wherein one semicircular hoop is a movable hoop 1, the other semicircular hoop is a static hoop 2, a rack 3 is arranged between two end parts of the movable hoop 1 and the static hoop 2, the static hoop 2 is fixedly connected with the rack 3, the movable hoop 1 is connected with the rack 3 through a sliding block 4, the sliding block 4 is fixedly connected with the movable hoop 1 and is in sliding connection with the rack 3, a ratchet 5 is supported on the sliding block 4, the ratchet 5 is meshed with the rack 3, a rotating shaft 6 of the ratchet is perpendicular to the rack 3, a pawl 7 is matched on the ratchet 5, the pawl 7 is rotatably connected to a wrench 8, the wrench 8 is connected with the rotating shaft 6 of the ratchet through a connecting rod 9, and the connecting rod 9 is rotatably connected with the rotating shaft 6 of the ratchet, And the spanner 8 is fixedly connected with the spanner 8, and the spanner 8 is of a door-shaped structure and is fixedly connected between the two connecting rods 9.

When the corrugated pipe butt joint device is used, the movable hoop 1 and the static hoop 2 are respectively clamped in grooves of two sections of butt joint corrugated pipes, the wrench 8 is lifted, the wrench 8 drives the pawl 7 to slide leftwards on the ratchet wheel 5, the wrench 8 is pressed downwards, the wrench 8 drives the pawl 7 to push the ratchet wheel 5 to roll rightwards on the rack 3, the ratchet wheel 5 drives the sliding block 4 to move rightwards, and the sliding block 4 drives the left corrugated pipe 10 to move rightwards through the movable hoop 1 to be close to the right corrugated pipe 11. The operations are repeated for a plurality of times until the left corrugated pipe 10 and the right corrugated pipe 11 are butted and fixedly connected together by adopting the sealing rubber ring 12.

Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
