Disclosure of Invention

The utility model aims at providing a traction trolley for tractor to overcome the defect that kiln car tractor can only one-way promotion kiln car among the prior art.

The utility model discloses an adopt following technical scheme to realize: a traction trolley for a tractor comprises a frame, wherein rollers are mounted at the bottom of the frame, bearing seats are fixedly mounted on two sides of the top of the frame respectively, at least one rotating shaft penetrates through the bearing seats on two sides, pushing heads are fixedly mounted on two sides of the rotating shaft respectively and are arranged between the bearing seats on two sides, a gear is fixedly mounted on one side of the rotating shaft and is arranged on the outer side of the bearing seat on one side, a hydraulic cylinder is fixedly mounted on one side of the gear on the frame and is connected with a rack matched with the gear through a telescopic rod, a supporting seat is mounted on one end of the rack on the frame, a sliding hole is formed in the supporting seat, and the rack penetrates through the sliding hole; and two ends of the frame are respectively provided with a traction hook, and the traction hooks on the two sides are respectively connected with a traction rope.

Furthermore, two rotating shafts penetrate between the bearing blocks on the two sides.

Furthermore, buffer layers are respectively arranged on two sides of the pushing head.

Further, the buffer layer is made of rubber.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model changes the situation that the existing kiln car tractor can only push the kiln car in one direction, the push head on the trolley for the existing kiln car tractor is generally a triangular push head hinged on the frame, which does not rotate when pushing the kiln car and can rotate relative to the frame when moving out from the bottom of the kiln car; the utility model has the advantages that the push head is arranged on the rotating shaft, the hydraulic cylinder pushes the rotating shaft to rotate through the rack, and further the rotation of the push head is realized; when the pushing head is vertical to the frame, the height of the pushing head is the highest and is higher than the height of the baffle at the bottom of the kiln car, at the moment, the kiln car can be pushed to move simultaneously when the bottom of the kiln car moves, and after the pushing head rotates and inclines for a certain angle, the height of the pushing head becomes lower at the moment and is lower than the height of the baffle at the bottom of the kiln car, at the moment, the kiln car can not be pushed to move simultaneously when the bottom of the kiln car moves; the height of the pushing head is controlled through rotation of the rotating shaft, so that the tractor can push the kiln car to move when the pushing head rotates no matter in the advancing direction or the retreating direction, the height of the tractor is higher than that of the baffle at the bottom of the kiln car, the tractor can move relative to the kiln car at the bottom of the kiln car when the tractor is lower than that of the baffle at the bottom of the kiln car, and the two-way pushing of the kiln car can be well realized.
