Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further described:
As illustrated in fig. 1 and 2, stretching machine is made up of tensioning head 302, the jack 301 connecting tensioning head, lowering or hoisting gear 2, shift unit 4 and running gear 6.Drag stretching machine by running gear 6 to walk, be elevated a thousand pieces of gold top 301 and tensioning head 302 by lowering or hoisting gear 2, move tensioning head 302 and jack 301 by shift unit 4.Lowering or hoisting gear 2 is arranged on shift unit 4, and like this, after stretching machine is dragged to operating position by running gear 6, the distance come directly towards between 303 and mould flatcar by shift unit 4 pairs of stretch-draw regulates.
In preferred embodiment of the present utility model, shift unit 4 is arranged on the stretch-draw platform 5 of running gear 6, shift unit 4 is a stretch-draw dolly, this stretch-draw dolly is provided with car body 401 and wheel 402, lowering or hoisting gear is arranged on the car body 401 of stretch-draw dolly, then connects a thousand pieces of gold top 301 by lowering or hoisting gear.
On stretch-draw platform 5, the axis direction along jack is provided with channel suspending rail 403, and wheel 402 is arranged in track 403, walks along track 403.Such setting can improve stretch-draw trolley travelling stationarity, makes the direction of motion of the walking of stretch-draw dolly and tensioning equipment in the same direction.
When carrying out operation, by running gear 6, stretching machine is transported to predetermined operating position, operative employee starts pipe pile die flatcar and stops to first about 1 meter of stretching machine, distance fine regulation is carried out by promoting stretch-draw dolly, be screwed in by horned nut on stretch-draw screw mandrel, point operation control pipe pile die flatcar switch runs to stretching machine side, contacts until the stretch-draw baffle plate of mould comes directly towards with stretch-draw, adjustment lowering or hoisting gear, makes stretch-draw top and horned nut locate on one wire.In the process, adjusted the position of whole lowering or hoisting gear by the position of adjustment stretch-draw dolly, thus stretch-draw top and stretch-draw plate washer are located along the same line, thus prevent from clashing between the stretch-draw plate washer of stretch-draw top and pipe pile die flatcar.
But in the middle of ongoing operations, still avoid stretch-draw top and stretch-draw plate washer to clash into completely, the utility model adopts following technical scheme to solve this technical problem.
Lowering or hoisting gear of the present utility model connects tensioning equipment by erecting by overhang 1.Lowering or hoisting gear is provided with lifting platform 208, and erecting by overhang 1 is made up of with hanging 103 adjustment screw mandrel 101 and adjusting nut 102.One end of screw mandrel 101 is regulated to be fixedly connected with lifting platform 208 by adjusting nut 102, the other end connects hanging 103, and connect jack 301 by hanging 103, erecting by overhang 1 is preferably two, lift the two ends of jack 301 respectively, keep the balance of tensioning equipment in lifting process.Come directly towards to prevent stretch-draw when being subject to external impacts and regulate screw mandrel distortion, between hanging 208 and adjustment screw mandrel, be provided with buffer spring 104, connect by one end of buffer spring the lower end regulating screw mandrel 101, the other end connects hanging 103.
Also can adopt rope type erecting by overhang, as steel wire rope, draw hawser etc.Buffer spring or steel wire rope etc. are set between hanging 208 and adjustment screw mandrel, the flexibility of erecting by overhang can be increased, well buffering and regulating action are played to the impulsive force of external force, prevent from regulating screw mandrel distortion, improve the impact resistance of whole device.
Lowering or hoisting gear can select following structure, comprises support 206, supporting seat 205, lifting platform 208 and lifting actuator, and lifting actuator is made up of motor 209, reduction box 210, lifting screw 203, lifting nut 24, lifting platform 208.Supporting 206 is fixedly installed on stretch-draw platform 5, supporting seat 205 is arranged on the top of support 206 and is positioned at the top on a thousand pieces of gold top 301, motor and reduction box are all arranged on supporting seat 205, one end of lifting screw 203 connects the output shaft of reduction box 210, the other end connects lifting nut 204, and lifting nut is fixedly connected on lifting platform 208.
