Description

Pipeline tightener

Technical Field

The utility model relates to the technical field of hydraulic engineering, in particular to a pipeline tightener.

Background

When the pipeline is connected with the pipeline joint, the pipeline is sleeved on the outer side of the pipeline joint, and the following two modes are adopted at present:

1. binding the pipeline on the outer side of the pipeline joint by utilizing an iron wire, and cutting off the iron wire by utilizing a tool when the pipeline is required to be disassembled later, so that the time and the labor are wasted, and the pipeline is easy to damage;

2. utilize clamp and bolt nut to connect, the clamp cup joints the pipeline outside, utilizes bolt nut to tighten the clamp for the pipeline fastening is in the pipeline joint outside, but bolt nut and clamp are metal material, and it can rust in the use, demolishs inconveniently, and influences the connection stability of pipeline and pipeline joint after rustting, and pipeline joint break away from easily.

Disclosure of Invention

To the defects of the prior art, the technical problem to be solved by the application is how to provide a pipeline tightener which is simple in structure, low in cost, stable and reliable.

In order to solve the technical problems, the utility model adopts the following technical scheme:

a pipeline tightener comprises a base, a ratchet shaft, a ratchet, a steel wire shaft and a spring; the base is U-shaped, steel wire shaft fixed mounting is in base one end, the ratchet shaft rotates the other end of installing at the base, the ratchet is installed on the ratchet shaft and rotates along with the ratchet shaft is synchronous, and wire rope is connected with ratchet shaft and steel wire shaft, spring fixed mounting is on the base, spring and ratchet interference fit.

Like this, the pipeline cup joints on the pipeline connects, adjusts the base to pipeline connects top, utilizes wire rope and wire axle and ratchet shaft to be connected, later rotates the ratchet shaft, drives the ratchet and rotates after rotating in place, loosens the spring, and the spring is under the elasticity effect, and with ratchet interference fit, spacing, realizes the locking to pipeline and pipeline joint. When the steel wire rope is required to be disassembled, the spring is reversely stirred, the spring is separated from the ratchet wheel, the ratchet wheel shaft is reversely rotated, the steel wire rope can be loosened, and the pipeline joint can be disassembled.

One end of the ratchet shaft is provided with a threaded hole, and one end of the ratchet shaft penetrates through the base and is connected with the ratchet shaft in a threaded mode through the base by means of bolts.

The ratchet wheel is provided with a rectangular hole, the section of one end of the ratchet wheel shaft connected with the bolt is rectangular, the ratchet wheel is sleeved on the ratchet wheel shaft, and the ratchet wheel is positioned on the inner side of the base.

Wherein, both ends of base all are fixed with the stiffener.

Wherein, the both ends of base have the breach of stepping down, and the lower extreme of base has the arcwall face.

Wherein, both the fixed pin and the rotating pin are provided with two through holes allowing the steel wire rope to pass through.

The base is made of sheet metal through stamping and bending.

In conclusion, the utility model has the advantages of simple structure, low cost, stability and reliability.
