Abstract

The utility model discloses a tractor used for towing linear materials such as a plastic pipe or a rod. The tractor comprises a frame component and a crawling traction component, wherein, the frame component comprises a base and a guide post arranged on the base; the crawling traction component comprises an upper bracket, a lower bracket, caterpillar bands and a caterpillar drive motor; the caterpillar bands are arranged on the upper bracket and the lower bracket respectively; the caterpillar drive motor is in drive fit with the caterpillar bands; the upper bracket and the lower bracket are matched with the guide post in a sliding manner to enable the caterpillar bands to form a pipe holding and towing structure; a lower bracket lifting adjustment device is arranged between the base and the lower bracket; and an upper bracket lifting adjustment device is arranged between the upper bracket and the lower bracket. When the tractor is used, the lower bracket is adjusted to move up and down through rotating the lower bracket lifting adjustment device, so that the traction is applied along the center line of the pipe or the rod; and after the lower bracket is adjusted, the upper bracket is adjusted to move downward through the upper bracket lifting adjustment device, so that a crawling traction component clamping workpiece is towed.

Description

Hauling machine

Technical field

The utility model relates to the hauling machine that is used to draw wire rods such as plastic tube or rod.

Background technology

Hauling machine is the pulling equipment that is used for plastic tube, excellent series products production line, it is a power with the rubber blanket on the crawler belt and tubing or the frictional force between the bar that extruded by extruding machine, tentatively typing, for tubing or bar provide certain tractive force and hauling speed, make tubing or bar cool off voluntarily, finalize the design and carry, with the tubing that obtains corresponding wall thickness or the bar of respective diameters with the speed of setting.

Be the tubing that guarantees to be produced or the quality of bar, hauling machine is except must having steadily uniformly tractive force and hauling speed, and tractive force also must apply along the center line of tubing or bar.Existing hauling machine is to move up and down by pneumatic accent center fixture adjusting crawling traction assembly to realize that tractive force applies along the center line of tubing or bar, pneumatic accent center fixture complex structure, the manufacturing cost height, and often break down, increase maintenance load and maintenance cost, also reduced production efficiency.

At above-mentioned deficiency, need to improve to existing hauling machine, make it can regulate the crawling traction assembly easily and move up and down and realize that tractive force applies along the center line of tubing or bar, simultaneously, also can reduce breakdown rate and device fabrication cost.

The utility model content

In view of this, the utility model provides a kind of hauling machine, and this hauling machine applies at realization tractive force and removed original pneumatic accent center fixture under the conveniently adjusted prerequisite of direction, has effectively reduced the manufacturing cost and the fault rate of hauling machine.

Hauling machine of the present utility model, comprise housing assembly and crawling traction assembly, described housing assembly comprises base and the guide pillar that is arranged on the base, described crawling traction assembly comprises bracket, bottom bracket, crawler belt and track drive motor, described bracket and bottom bracket all with guide pillar being slidingly matched along the mode that guide pillar slides up and down, the track drive motor that is respectively arranged with crawler belt on bracket and the bottom bracket and cooperates with track drive, article two, crawler belt is oppositely arranged and switched in opposite formation tubing clamping hitch structure, be provided with the bottom bracket elevation and subsidence regulating device between described base and the bottom bracket, be provided with the bracket elevation and subsidence regulating device between described bracket and the bottom bracket.

Further, described bracket elevation and subsidence regulating device is a hydraulic jack, and bracket is withstood in the upper end of described hydraulic jack, and bottom bracket is withstood in the lower end;

Further, described bottom bracket elevation and subsidence regulating device is a screw mandrel, and screw mandrel one end withstands base and is rotatably assorted with base, and the other end is threaded with bottom bracket;

Further, described screw mandrel is provided with the screw mandrel rotary handle.

The beneficial effect of utility model: hauling machine of the present utility model, comprise housing assembly and crawling traction assembly, described housing assembly comprises base and the guide pillar that is arranged on the base, described crawling traction assembly comprises bracket, bottom bracket, crawler belt and track drive motor, described bracket and bottom bracket all with guide pillar being slidingly matched along the mode that guide pillar slides up and down, the track drive motor that is respectively arranged with crawler belt on bracket and the bottom bracket and cooperates with track drive, article two, crawler belt is oppositely arranged and switched in opposite formation tubing clamping hitch structure, be provided with the bottom bracket elevation and subsidence regulating device between described base and the bottom bracket, be provided with the bracket elevation and subsidence regulating device between described bracket and the bottom bracket, during use, regulating bottom bracket by rotation bottom bracket elevation and subsidence regulating device moves up and down, tractive force is applied along the center line of tubing or bar, easy and simple to handle, after regulating, regulating bracket by the bracket elevation and subsidence regulating device again moves down, clamping work pieces, this hauling machine has saved original pneumatic accent center fixture, structure is simpler, and manufacturing cost and fault rate are all significantly reduced.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural representation of the present utility model;
