Abstract
The invention discloses a pneumatic chaining device for a traction trolley, which comprises the traction trolley, a cylinder and a bull-head-shaped hook. The traction trolley is in movable connection with the bull-head-shaped hook through a pin shaft, the cylinder is arranged above the bull-head-shaped hook and is arranged in an inclined mode, the lower portion of the cylinder is provided with a movable piston rod in movable connection with the pull head hook through a hinge, a support is vertically fixed on the traction trolley and fixedly connected with the cylinder, tension springs are symmetrically installed on two sides of the cylinder, the tail ends of the two tension springs are respectively and movably connected with two tension spring seats, the top ends of the two tension springs are movably connected with adjusting screws and connected with the support through the adjusting screws, two sides of the bull head hook are respectively provided with a traction chain and a traction chain roller, the hook nose of the bull-head-shaped hook can be inserted in a gap of the traction chain rollers, and the traction trolley moves along with the traction chains.
Description
Technical field
The present invention relates to a kind of pneumatic chaining device, specifically, is a kind of pneumatic chaining device of trailer wagon.
Background technology
Seamless steel pipe be a kind ofly have hollow section, periphery does not have the circle of seam, square, rectangle steel, is the shaped steel that is widely used, seamless steel pipe is to process hollow billet with steel ingot or solid pipe perforated, processes through hot rolling, cold rolling or cold group then.Because of its manufacturing process is different, be divided into two kinds in hot rolling (extruding) seamless steel pipe and cold-drawn (rolling) seamless steel pipe again.Cold-drawn (rolling) pipe is divided into two kinds of round tube and special pipes again; The production process route of cold-drawn (rolling) seamless steel pipe is very long, comprises circular pipe blank → heat → bore a hole → take the lead → anneal → pickling → oiling (copper facing) → multi-pass cold-drawn (cold rolling) → base pipe → heat treatment → aligning → water pressure test (flaw detection).The realization of this production process route, the commercial production streamline of being made up of many professional equipments is carried out, and its professional equipment comprises: the pneumatic chaining device of a kind of trailer wagon in centreless cold drawing steel tube commercial production streamline.
Summary of the invention
The invention discloses a kind of pneumatic chaining device of trailer wagon, its objective is provides a kind of pneumatic chaining device, and the power of haulage chain is controlledly passed to trailer wagon.
The objective of the invention is to realize like this: a kind of pneumatic chaining device of trailer wagon, this device comprises trailer wagon, cylinder and ox head hook, trailer wagon flexibly connects through bearing pin and ox head hook; Cylinder is above the ox head hook, and cylinder is obliquely installed, and is provided with piston rod in the bottom of cylinder; Piston rod flexibly connects through hinge and ox head hook, and vertical fixing has support on the trailer wagon, and cylinder is fixedly connected with support; The bilateral symmetry of cylinder is installed extension spring, and the end of two extension springs flexibly connects with two extension spring seats respectively, and the top of two extension springs and adjusting screw(rod) flexibly connect; And join through adjusting screw(rod) and support; The both sides of ox head hook are provided with haulage chain and haulage chain roller, and the hook nose of ox head hook can insert in the gap of haulage chain roller, moves with haulage chain.
Description of drawings
Fig. 1 is the scheme of erection of this invention.
Wherein: 1-trailer wagon, 2-bearing pin, 3-support, 4-cylinder, 5-adjusting screw(rod), 6-extension spring, 7-extension spring seat, 8-haulage chain, 9-ox head hook, 10-haulage chain roller, 11-piston rod.
The specific embodiment
As shown in Figure 1, a kind of pneumatic chaining device of trailer wagon, this device comprises trailer wagon 1, cylinder 4 and ox head hook 9; Trailer wagon 1 flexibly connects through bearing pin 2 and ox head hook 9, and cylinder 4 is above ox head hook 9, and cylinder 4 is obliquely installed; Be provided with piston rod 11 in the bottom of cylinder 4, piston rod 11 flexibly connects through hinge and ox head hook 9, and vertical fixing has support 3 on the trailer wagon 1; Cylinder 4 is fixedly connected with support 3, and the end that the bilateral symmetry of cylinder 4 is installed 6, two extension springs 6 of extension spring flexibly connects with two extension spring seats 7 respectively; The top of two extension springs 6 and adjusting screw(rod) 5 flexibly connect, and join through adjusting screw(rod) 5 and support 3, and the both sides of ox head hook 9 are provided with haulage chain 8 and haulage chain roller 10; The hook nose of ox head hook 9 can insert in the gap of haulage chain roller 10, with haulage chain 8 motions.
When cylinder 4 is filled with air, piston rod 11 stretches out, and the hook nose of ox head hook 9 is inserted among the gap of haulage chain roller 10, along with haulage chain 8 moves; After cylinder 4 was deflated, extension spring 6 was pulled out the hook nose of ox head hook 9 among the gap of haulage chain roller 10, broke away from haulage chain 8.
