Detailed Description
The following is a further description of embodiments of the invention, taken in conjunction with the accompanying drawings:
1-3, the ultrathin electric trailer with the bidirectional hydraulic car pusher comprises an electric trailer track 7, a wheel assembly 5, an electric trailer frame and a kiln car track 10; the wheel assembly 5 consists of a plurality of electric trailer wheels and a driving device, wherein the electric trailer wheels are symmetrically arranged on two sides of the electric trailer frame and can drive the electric trailer 1 to move along the electric trailer track 7 under the action of the driving device; a kiln car track 10 is arranged on the electric trailer frame; the hydraulic car pusher (6) is also included; the rail surface elevation of the electric trailer rail 7 is level with the top surface of the terrace; the electric trailer frame is a rectangular frame structure consisting of a main beam 3 and a secondary beam 4, the main beam 3 is arranged parallel to an electric trailer track 7, and electric trailer wheels are arranged on the main beam 3; the secondary beam 4 and the main beam 3 are vertically erected on the main beam 3, the secondary beam 4 is provided with parallel inner rails and outer rails, wherein the inner rails are trolley tracks 11, the outer rails are kiln car tracks 10, and 2 hydraulic trolley machines 6 are respectively arranged at two ends of the trolley tracks 11; each hydraulic car pusher 6 consists of a car pusher frame and car pusher wheels, wherein the car pusher wheels are arranged on the car pusher frame and can drive the car pusher frame to move along a car pusher track 11 under the action of a bidirectional hydraulic cylinder 9; an elastic clamping block 8 is arranged on the trolley frame, the elastic clamping block 8 can rotate unidirectionally along the movement direction of the hydraulic trolley 6 to the inner side of the electric trailer track 7 and can be matched with a baffle suspended at the bottom of the kiln car, so that the synchronous movement of the hydraulic trolley 6 and the kiln car 2 is realized.
The main beam is made of welded T-shaped steel, and the secondary beam is made of L-shaped steel.
The bidirectional hydraulic cylinder 9 is arranged on the main beam 3, and the fixing seat of the bidirectional hydraulic cylinder is arranged on the side surface of the hydraulic cylinder body.
The kiln car track 10 and the car pusher track 11 are respectively and correspondingly provided with extension tracks on the ground at both sides.
The kiln car track 10 is made of rectangular steel rails, and the height of each rectangular steel rail is 40-50 mm.
The elastic clamping block is provided with a reset spring at the other side of the rotatable direction.
According to the ultrathin electric trailer with the bidirectional hydraulic car puller, 2 hydraulic car puller 6 which are oppositely arranged can push the kiln car 2 in the bidirectional direction along the running direction perpendicular to the electric trailer 1, and are used for pulling the kiln car 2 on the ground to the electric trailer 1 or pushing the kiln car 2 on the electric trailer 1 to the ground; the electric trailer 1 is capable of reciprocating along an electric trailer track 7 laid on the ground.
The electric trailer frame adopts a frame structure that a welded T-shaped steel main beam 3 and an L-shaped steel secondary beam 4 are lapped, and has light weight and high strength. Wherein 2 welded T-shaped steel girders 3 are arranged in parallel along the direction of an electric trailer track 7 and bear and transfer the weight from a kiln car and the bricks carried by the kiln car; the 2L-shaped steel secondary beams 4 are erected on the top of the main beams and span between the 2 main beams 3, and the secondary beams 4 are used for transmitting the loads of the kiln car 2 and the bricks carried by the kiln car to the main beams 3. The frame type connecting structure of the main beam 3 and the secondary beam 4 reduces the overall height of the electric trailer frame, so that the distance between the electric trailer frame and the ground is obviously reduced, and the electric trailer 1 almost closely runs on the ground. Meanwhile, the weight of the electric trailer frame is reduced by the structure, and the strength and the rigidity of the electric trailer frame are obviously improved; through tests, when the total mass of the kiln car 2 and the bricks carried by the kiln car reaches 15 tons, the total deformation of the electric trailer frame after being carried is less than 2mm.
