Detailed Description

As shown in the attached drawings 1-6, the utility model comprises a base 3, a bracket 2 and a runner frame 1, wherein the base 3 is formed by welding profile steel and steel plates, the bracket 2 is fixedly arranged on the base 3, and the runner frame 1 is arranged on the bracket 2.

The runner frame 1 is including connecting crossbeam 102 and installing the runner 101 at both ends about connecting crossbeam 102, it has two and be central symmetry and install between two runners 101 to connect crossbeam 102, two runners 101 and two connect crossbeam 102 and adopt bolted connection to fix into a whole, runner 101 runner tread both sides are equipped with rim 104, rim 104 plays the spacing effect of direction, wherein the processing of tread one side rim has the teeth of a cogwheel, form gear 105, be used for driving the runner frame and rotate, the round hole has been seted up to the spoke of runner 101, be used for interlude safety pin, connect crossbeam 102 upper surface along the length to set up a plurality of slot holes, be used for with fixed connection of crossing cab apron 103 fixed, it is fixed with fixed cab apron 103 of crossing the work piece, then install on connecting crossbeam 102.

The carriage includes a frame body, and a support wheel 202 and a driving gear 203 mounted on the frame body. The frame body comprises a driving frame 201 and a driven frame 207 which are formed by welding. Four supporting wheels 202 are provided, 2 of the four supporting wheels are arranged on the driving frame 201, the other 2 supporting wheels are arranged on the driven frame 207, the supporting wheels 202 are matched with the wheel rims 104 on the wheel treads of the rotating wheels 101, and the contact point is positioned between the two wheel rims 104, so that the guiding and limiting effects are realized.
