Abstract
A hydraulic pushing device mainly solves the problems that an existing hydraulic pushing device is strenuous in operation and potential safety hazards exist in the existing hydraulic pushing device. The hydraulic pushing device is characterized in that a fixing plate (5) is arranged on a support (2), a second pipe clamp (6) is arranged on the fixing plate (5), the second pipe clamp (6) and a first pipe clamp (4) are the same in structure and are installed in the same direction, both the second pipe clamp (6) and the first pipe clamp (4) are composed of jackets (7), clamping blocks (8), elastic pieces (9) and cover plates (10), the inner walls of the jackets (7) are in a cone shape, the number of the clamping blocks (8) is at least three, the outer walls of the clamping blocks (8) are matched with the inner walls of the jackets (7), and the elastic pieces (9) are located between the clamping blocks (8) and the cover plates (10). According to the hydraulic pushing device, the pipe clamps used for clamping pipe fittings when the pipe fittings are lifted upwards are added, and therefore the hydraulic pushing device has the advantages of being simple in structure, saving in operation, safe and reliable.
Description
Technical field
The utility model relates to the device of a kind of well-digging or underground intubate, is specifically related to a kind of hydraulic pressure pusher.
Background technology
Existing hydraulic pressure pusher mainly is comprised of hydraulic cylinder, Hydraulic Station, support and pipe clamp, be mainly used in well-digging or underground intubate etc., pipe clamp links to each other with hydraulic cylinder, and pipe fitting passes support and clamped by pipe clamp, the hydraulic cylinder action advances pipe fitting, pipe fitting is generally more piece and is threaded, and pipe clamp is comprised of wedge shape fixture block and overcoat, and the wedge shape fixture block is by overcoat extruding chucking pipe fitting when hydraulic cylinder advances, pipe fitting moves together in company with hydraulic cylinder, when hydraulic cylinder shrank, wedge opened, the pipe fitting transfixion.Hydraulic cylinder stops when arriving top dead centre, then accesses next pipe joint spare, continuously is pressed into a plurality of pipe fittings underground.There is following technological deficiency in this hydraulic pressure pusher: because hydraulic cylinder drives when carrying on the pipe clamp, there is larger frictional force between pipe clamp and the pipe fitting, pipe fitting can be pulled up, therefore in use, need manually to block pipe fitting with pipe wrench, to avoid pipe fitting to be raised together in company with pipe clamp, the operation effort, in case the clamping force between pipe clamp and the pipe fitting is larger, operating personnel will be taken up, come to harm easily, have potential safety hazard.
The utility model content
The deficiency of requiring great effort and having potential safety hazard in order to overcome existing hydraulic pressure pusher operation, the utility model provides a kind of hydraulic pressure pusher, this hydraulic pressure pusher has increased when carrying on the pipe fitting pipe clamp of chucking pipe fitting, has simple in structure, rapid operation and safe and reliable characteristics.
The technical solution of the utility model is: a kind of hydraulic pressure pusher comprises hydraulic cylinder, support, portable plate and the first pipe clamp, hydraulic cylinder is fixed on the support top and links to each other with Hydraulic Station, the piston rod of hydraulic cylinder connects portable plate, portable plate is provided with the first pipe clamp, support is provided with fixed head, described fixed head is provided with the second pipe clamp, and the structure of described the second pipe clamp and the first pipe clamp is identical and install in the same way; Described the second pipe clamp and the first pipe clamp form by overcoat, fixture block, flexure strip and cover plate, and the inwall of overcoat is conical, and the inwall of at least three of fixture blocks and its outer wall and overcoat matches, and flexure strip is between fixture block and cover plate.
Described hydraulic cylinder is two and symmetrical.
The utlity model has following beneficial effect: owing to take such scheme, when hydraulic cylinder is depressed, the relative overcoat of fixture block in the first pipe clamp moves upward, the chucking pipe fitting, meanwhile, the relative overcoat of fixture block in the second pipe clamp moves downward, and unclamps pipe fitting, and pipe fitting moves downward together in company with portable plate; When carrying on the hydraulic cylinder, the relative overcoat of the fixture block in the first pipe clamp moves downward, and unclamps pipe fitting, and meanwhile, the relative overcoat of the fixture block in the second pipe clamp moves upward, the chucking pipe fitting, and pipe fitting is motionless, mentions after top dead center on the hydraulic cylinder and stops, and accesses next pipe joint spare.Need not manually take pipe wrench to block pipe fitting during operation, simple in structure, rapid operation, safe and reliable.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structure sectional views of the first pipe clamp 4 and the second pipe clamp 6 among Fig. 1.
1-hydraulic cylinder among the figure, 2-support, 3-portable plate, 4-the first pipe clamp, 5-fixed head, 6-the second pipe clamp, 7-overcoat, 8-fixture block, 9-flexure strip, 10-cover plate, 11-pipe fitting.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of hydraulic pressure pusher comprises hydraulic cylinder 1, support 2, portable plate 3 and the first pipe clamp 4, hydraulic cylinder 1 is fixed on support 2 tops and links to each other with Hydraulic Station, the piston rod of hydraulic cylinder 1 connects portable plate 3, portable plate 3 is provided with the first pipe clamp 4, support 2 is provided with fixed head 5, and described fixed head 5 is provided with the second pipe clamp 6, and the structure of described the second pipe clamp 6 and the first pipe clamp 4 is identical and install in the same way; Described the second pipe clamp 6 and the first pipe clamp 4 form by overcoat 7, fixture block 8, flexure strip 9 and cover plate 10, and the inwall of overcoat 7 is conical, and the inwall of 8 at least three of fixture blocks and its outer wall and overcoat 7 matches, and flexure strip 9 is between fixture block 8 and cover plate 10.Owing to take technique scheme, when hydraulic cylinder 1 was depressed, the fixture block 8 relative overcoats 7 in the first pipe clamp 4 moved upward, chucking pipe fitting 11, meanwhile, the fixture block 8 relative overcoats 7 in the second pipe clamp 6 move downward, unclamp pipe fitting 11, pipe fitting 11 moves downward together in company with portable plate 3; When carrying on the hydraulic cylinder 1, the fixture block 8 relative overcoats 7 in the first pipe clamp 4 move downward, and unclamp pipe fitting 11, meanwhile, the fixture block 8 relative overcoats 7 in the second pipe clamp 6 move upward, chucking pipe fitting 11, pipe fitting 11 is motionless, mentions after top dead center on the hydraulic cylinder 1 and stops, and accesses next pipe joint spare 11.Need not manually take pipe wrench to block pipe fitting 11 during operation, simple in structure, rapid operation, safe and reliable.
Described hydraulic cylinder 1 is two and symmetrical.Hydraulic cylinder 1 also can arrange a plurality of, but when design, each hydraulic cylinder must be synchronously.
