In order to prevent the first hook 41 or the second hook 42 from colliding with the tension spring 62 during rotation, the bottom walls of the first hook 41 and the second hook 42 close to the vehicle body 1 are both provided with accommodating grooves 47 for accommodating the tension spring 62, and the first hook 41 and the second hook 42 do not collide with the tension spring 62 during overturning under the effect of the accommodating grooves 47, so that the possibility of damage to the tension spring 62 is reduced, and the service life of the tension spring 62 is prolonged.

When the telescopic assembly 5 is in the extended state, the tension spring 62 connected to the first hook 41 is in the stretched state, and the tension spring 62 connected to the second hook 42 is in the normal state. Under the action of the reset assembly 6 and the shifting block 531, when the telescopic assembly 5 is in the shortened state, the tension spring 62 connected with the first hook 41 is in a normal state, and the tension spring 62 connected with the second hook 42 is in a stretched state, and the shifting block 531 close to the second hook 42 is abutted to the shifting piece 44 arranged on the second hook 42. An operator can lift up and drop down the first hook 41 and the second hook 42 by controlling the telescopic assembly 5, so that the first hook 41 or the second hook 42 hooks a T-shaped stop block which is arranged on the furnace car and matched with the hooks, and the furnace car is dragged to move by the connection of the first hook 41 or the second hook 42.

In order to facilitate repair and reduce manufacturing cost, the telescopic assembly 5 comprises a handle 51, a driven rod 52 and a working rod 53 which are sequentially hinged, the handle 51 is hinged on the vehicle body 1, the driven rod 52 and the working rod 53 are both perpendicular to the rotating shaft 43, an operator can control the working rod 53 to move along the axis direction by rotating the handle 51, so that the purpose of controlling the whole length of the telescopic rod is achieved, the shifting block 531 is arranged on the working rod 53, and the purpose of controlling the first hook 41 or the second hook 42 to turn over is achieved by controlling the position of the shifting block 531. In order to limit the working rod 53 to move only along the axial direction, a plurality of stoppers 54 are welded to the vehicle body 1, and the working rod 53 is movably disposed through the stoppers 54.

As shown in fig. 1, a top cover 11 is arranged on the vehicle body 1, and an opening for the first hook 41, the second hook 42 and the handle 51 to penetrate out is formed in the top cover 11, so that dust is prevented from falling into the inner side of the top cover 11 and being adhered to the reset component 6 and the telescopic component 5, and the phenomenon that the dust is stuck due to adhesion is avoided. The side walls of the first hook 41 and the second hook 42 are provided with a blocking piece 45 which can collide with the top cover 11 and is used for preventing the first hook 41 or the second hook 42 from completely turning out of the top cover 11, so that the first hook 41 and the second hook 42 are prevented from being unable to reset, and the phenomenon that the push-pull assembly cannot normally work is caused.

In order to avoid the first hook 41 or the second hook 42 turning back to the lower part of the top cover 11 and separating from the furnace car due to unexpected accident after hooking with the furnace car, the side walls of the first hook 41 and the second hook 42 far away from the car body 1 are both connected with a limiting piece 46 through bolts, and the bolts are movably arranged on the limiting piece 46 in a penetrating way. When the first hook 41 or the second hook 42 is used, the position of the first hook 41 or the second hook 42 can be limited by the limiting piece 46, so that the first hook 41 or the second hook 42 is prevented from being overturned. In the present embodiment, the upper surface of the first hook 41 or the second hook 42 when placed horizontally is at the same level as the upper surface of the top cover 11.

The use process comprises the following steps:

when the stove carriage needs to be pulled forwards, the handle 51 is pulled up, the first hook 41 is lifted at the moment, and the second hook 42 falls down. The hydraulic oil cylinder 2 is started, the hydraulic oil cylinder 2 extends out of the pushing car body 1 to travel, and when the first hook 41 touches a stop block at the lower part of the furnace car (the furnace car is provided with 5 groups of T-shaped stop blocks at the lower part of the car body 1), the furnace car moves forwards to finish the moving process.

When the stove carriage needs to be pulled backwards, the handle 51 is pressed, the second hook 42 is lifted at the moment, and the first hook 41 falls down. And starting the hydraulic cylinder 2, withdrawing the hydraulic cylinder 2 to pull the furnace body 1 to travel, and moving the furnace body backwards after the second hook 42 touches a stop block at the lower part of the furnace body (the furnace body is provided with 5 groups of T-shaped stop blocks at the lower part of the furnace body 1) to finish the moving process.

The whole operation process is simple and convenient, and the structure is simple and easy to overhaul. And whole push-and-pull process factor of safety is higher, and the horizontal plane degree requirement of stove bottom and automobile body 1 is lower simultaneously, and when lifting bottom of the car and first couple 41 or second couple 42 when not at same horizontal plane, first couple 41 and second couple 42 homoenergetic after the upset cooperate with the stove car, are difficult for unhooking in the transportation, the effectual increase of avoiding manufacturing cost.
