Abstract
The utility model relates to the technical field of continuous tube rigs, in particular to a low noise injection head. The injection head comprises a continuous tube, a motor, a chain, a vertical tensioning oil cylinder, clamping oil cylinders and clamping devices; the clamping oil cylinders push the clamping devices with clamping blocks to clamp one side of the chain, and the chain is tensioned through the vertical tensioning oil cylinder; and two horizontal tensioning rollers are additionally arranged on the other side of the chain. The low noise injection head realizes simple structure, lowers the noise during the operating process and overcomes the defect that the conventional injection head can not achieve simple structure and low noise at the same time.
Description
Technical field:
The utility model relates to a kind of continuous pipe working rig technical field, particularly a kind of low noise injection head.
Background technology:
The injection head external and domestic continuous pipe working rig is disposed, there is dual mode in its chain tension, and a kind of is vertical tensioning, and a kind of is horizontal tensioning.Vertically tension structure is simple, but the slack list when operation because vibration, noise is bigger; Though horizontal tensioning has reduced noise, because chain is longer, the tensioning hydro-cylinder that needs is more, the structure relative complex.
The utility model content:
The technical problems to be solved in the utility model provides a kind of low noise injection head, and this injection head has realized that the while simple in structure reduces noise in operation process.Existing injection head noise little but complex structure or deficiency simple in structure but that noise is big have been overcome.
Technical solution adopted in the utility model is: a kind of low noise injection head, form by continuous pipe, motor, chain, vertical tensioning hydro-cylinder, clamping cylinder and clamping device; Clamping cylinder promotes to have one side clamping of the clamping device of grip block with chain, by vertical tensioning hydro-cylinder tension chain, in two horizontal tension rollers of another side increase of chain.
The beneficial effects of the utility model are: the utility model is vertically regulated chain center to center distance owing to adopted vertical chain drive, the structure of two side wheel tensionings, thereby have simple in structure, the effect of low noise.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of low noise injection head is made up of continuous pipe 1, motor 2, chain 3, horizontal tension rollers 4, vertical tensioning hydro-cylinder 5, clamping cylinder 6 and clamping device 7; Pipe 1 penetrates injection head continuously, clamping cylinder 6 promotes to have one side clamping of the clamping device 7 of grip block with chain 3, by vertical tensioning hydro-cylinder 5 tension chains 3, another side at chain 3 increases by two horizontal tension rollers 4, horizontal tension rollers 4 has played the effect of horizontal tension chain 3, has reduced the noise that the vibration of in the injection head running because slack list brings.
