Abstract
The utility model relates to a steel pipeline expanding pull rod bush fixing device which comprises a pull rod and a wall. An expanding head is mounted on the pull rod, a flange bush is sleeved at one end of the pull rod, a boss is arranged on the outer side of the flange bush, one side of the wall is provided with a groove connected with the boss in a matched manner, connecting plates are mounted at the top and the bottom, connected with the wall, of the flange bush respectively, and each connecting plate is fixed through a set screw. The steel pipeline expanding pull rod bush fixing device is reasonable in structure and convenient to mount and demount, efficiency of a tooling between the flange bush of the pull rod and the wall is improved greatly, and time for a path changing process of expanding products is shortened.
Description
Technical field
The utility model relates to hole enlargement equipment technical field, especially steel pipeline hole enlargement drag link sleeve tube fixing device.
Background technology
At present, on market, the manufacturer of production hole enlargement pull bar seldom, produces that to have the manufacturer of the hole enlargement pull bar that the performances such as high rigidity, tensile strength and toughness are qualified few especially.Domestic market mainly depends on import, but import price is expensive, and the cycle is long, affects duration and partner's interests.
In prior art, as depicted in figs. 1 and 2, comprise pull bar 3, on described pull bar 3, cover has sleeve 2, described sleeve 2 ends are by a plurality of screws 4 and body of wall 1 locking, and its connected mode is simple, and cost is low, but it installs trouble, employing screw location, locates inaccurately, and length expends time in, extend hole enlargement product and change procedure, inefficiency.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of steel pipeline hole enlargement drag link sleeve tube fixing device, thereby has improved positioning precision, and installation and removal are easy, saved the time that hole enlargement product changes procedure, improved operating efficiency.
The technical scheme that the utility model adopts is as follows:
A kind of steel pipeline hole enlargement drag link sleeve tube fixing device, comprise pull bar, on described pull bar, expanding head is installed, one end of described pull bar is equipped with flange sleeve, the arranged outside of described flange sleeve has boss, also comprises body of wall, and described body of wall one side is provided with the groove being connected with described boss, top and bottom after described flange sleeve and wall connecting is separately installed with connecting plate, and described connecting plate is fixed by holding screw.
Further improvement as technique scheme:
Described connecting plate becomes " ┎ ┐ " structure;
The cross section squarely structure of described flange sleeve;
Described flange sleeve is placed on the outer circumference surface of pull bar by lubricating sleeve;
On described flange sleeve, have pin-and-hole, fastening by alignment pin after described flange sleeve and body of wall are connected.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, and installation and removal are convenient, has greatly improved the efficiency of frock between the flange sleeve of pull bar and body of wall, has shortened the time that hole enlargement product changes procedure.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Fig. 3, Fig. 4 and Fig. 5, the steel pipeline hole enlargement drag link sleeve tube fixing device of the present embodiment, comprise pull bar 3, expanding head 5 is installed on pull bar 3, and one end of pull bar 3 is equipped with flange sleeve 6, and the arranged outside of flange sleeve 6 has boss 7, also comprise body of wall 1, body of wall 1 one sides are provided with the groove being connected with boss 7, and the top and bottom after flange sleeve 6 is connected with body of wall 1 is separately installed with connecting plate 11, and connecting plate 11 is fixing by holding screw 10.
11 one-tenth " ┎ ┐ " structures of connecting plate.
The cross section squarely structure of flange sleeve 6.
On flange sleeve 6, have pin-and-hole 9, flange sleeve 6 is fastening by alignment pin 12 after being connected with body of wall 1.
In practical set process, first on pull bar 3, by lubricating sleeve 8, be placed on flange sleeve 6, groove fit clamping by the boss on flange sleeve 67 with body of wall 1, then the top and bottom after flange sleeve 6 is connected with body of wall 1 is installed connecting plate 11 respectively, finally with holding screw 10, tightens.During dismounting, by unclamping holding screw 10, dismounting connecting plate 11, then parting flange sleeve 6 and body of wall 1.Its mounting or dismounting are easy, and connection reliability is good, and installation accuracy is good, and operating efficiency is high.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
