Background technology
Steel tube expansion to steel pipe carry out overall expanding time, need by the weld seam of steel pipe rotate to directly over clamp with steel pipe clamp, steel pipe is sent to or retreats.Steel pipe clamp on external steel tube expansion, the hydraulic cylinder that adopts adds eccentric mechanism more.Its weak point is, with eccentric wheel clamping, to the steel pipe of different wall, needs below jaw, to add height adjustment pad sheet, inconvenient operation; By thickness of steel pipe error, clamp reliable not.
Chinese patent CN201046485 discloses a kind of steel pipe clamp for this reason, there are two otic placodes in described clamp block front, otic placode processes otic placode flange mounting hole, cydariform axle is arranged on otic placode flange, cydariform axle is provided with two cambered surface covers, the large installing hole of lower clamp is enclosed within cambered surface cover periphery, cambered surface is made to overlap axial location with the cambered surface jacket gland be connected on lower clamp, the extending-board of lower clamp afterbody, penetrate in oblong aperture reserved in clamp block, upper clamp is hinged on the little installing hole on lower clamp by upper clamp axle, hydraulic cylinder is uprightly arranged on the square flange at upper clamp rear portion, the piston rod head of hydraulic cylinder is provided with bulb, bulb is contained in spheric seating and also fastens with bulb gland, spheric seating is placed on the upper surface of lower clamp afterbody extending-board, and can slippage thereon.
Adopt the structure described in Chinese patent CN201046485, need the device such as hydraulic cylinder and piston rod integrated model comparatively numerous and diverse and huge, be not easy to the steel pipe that operator clamps pipe with small pipe diameter.For the steel pipe clamping of pipe with small pipe diameter, if directly held with a hand, both hands are easily hurt by some sharp places of steel pipe table wall again, and steel pipe docks other input/output ports, using steel pipe as the dispatch tube in chemical machinery by inconvenience.
Summary of the invention
Technical problem to be solved by this invention is to provide one can regulate bore, and is convenient to manual operations, for clamping the steel pipe clamp of pipe with small pipe diameter steel pipe.
For solving the problems of the technologies described above, the invention provides following technical scheme:
A kind of steel pipe clamp, comprise a sleeve, sleeve front portion is provided with the relative open slot in two positions, a threaded rod is provided with in described sleeve, threaded rod is provided with the first nut and the second nut, threaded rod to pass and by the first nut locking in sleeve rear end, threaded rod front end is connected with the second nut thread from sleeve rear end, also comprise a quadric chain, this quadric chain penetrates into sleeve front portion by described open slot, this quadric chain to be connected with two front bars by two rear bars and to form, hinged between adjacent links, pin joint after wherein pin joint comprises one, two middle pin joints and a front pin joint, the front end of two front bars is respectively equipped with the caliper of a band bend, the bend of two calipers is towards relatively, two threaded rods form front pin joint by a pinned connection, this bearing pin is fixed on sleeve lining, two rear bars form rear pin joint by another pinned connection, this bearing pin is fixed on threaded rod front end.
Adopt a kind of steel pipe clamp of the present invention, there is following effect:
First the first nut will will be loosened during use, then manual hold threaded rod shifts threaded rod onto suitable position, due in quadric chain between two rear bars hinged bearing pin be fixed on threaded rod front end, subtended angle all can occur for described two rear bars and two threaded rods hinged with rear bar changes, also can there is subtended angle change in the caliper being located at two threaded rod front ends like this, reach the object regulating clamping caliber like this.
Double leval jib function is penetrated in sleeve by open slot, and is fixed on the bearing pin of sleeve lining by one, realize the location of quadric chain relative to sleeve.
After being adjusted to suitable caliper subtended angle, by the position of the first nut locking threaded rod relative to sleeve, i.e. complete whole adjustment process.Adopt manual operation in adjustment process, do not adopt the equipment such as motor and cylinder.
Further, the threaded rod between described sleeve rear end and the second nut is arranged with Compress Spring.
After sheathed Compress Spring, directly can be regulated the movement of threaded rod by the first nut, rotating nut, nut is moved relative to threaded rod forward end, shifts out after such threaded rod from sleeve rear end, Compress Spring can be further compressed; If reverse rotation nut, nut is moved to the back-end relative to threaded rod, then can loosen between threaded rod rear end and sleeve, like this under the reset response of Compress Spring, threaded rod front end can move forward.
So just do not need hand-held threaded rod, the control of threaded rod directly can be realized by the rotation of the first nut.
Further, described caliper is hinged on the front end of front bar, and be also provided with connecting plate between two calipers, caliper is hinged on connecting plate.
Certain caliper can be fixed in front bar, but such adjustment is dumb, in order to regulate the subtended angle between two calipers neatly, hereby caliper is hinged on the front end of front bar, and arranges the connecting plate hinged with caliper.And the existence of connecting plate can strengthen the connectivity robustness between two calipers and steel pipe.
Further, the bend of described caliper is provided with link.
The setting of link is that conveniently steel pipe clamp hangs on body of wall.
Accompanying drawing explanation
Fig. 1 cuts open structural representation in a kind of steel pipe clamp embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
