Abstract

The utility model discloses an emergency traction structure. The emergency traction structure comprises a traction base which is fixed on the ground by a foundation bolt. One end of a connecting rod is connected with the traction base through a connecting shaft, while the other end of the connecting rod is connected with a rotating pulley through a wheel axle; the rotating pulley is provided with a steel wire rope; the length of the connecting rod depends on the height of a lifting lug on an engineering vehicle; a condition that the lifting lug and the bottom surface of the rotating pulley are on the same level is ensured so as to be beneficial to the transfer of a driving force. When the engineering vehicle loses power and can not travel autonomously in an emergency, the two ends of the steel wire rope wound around the rotating pulley of an emergency traction device are respectively connected with a hook of a travelling crane or a hoist, and the lifting lug of the engineering vehicle, the traveling crane or the hoist provides the appropriate driving force to smoothly drag the engineering vehicle to the outside of a steel structural platform and then the engineering vehicle is overhauled and maintained, so that the unnecessary economic loss is reduced and the normal production of steel mills is ensured.

Description

A kind of urgent hitch structure
Technical field
The utility model relates to the engineering truck technical field of field of metallurgy, is specifically related to a kind of urgent hitch structure.
Background technology
The engineering truck of carrying molten steel or other equipment is all the important carrier of realizing various necessary functions, the power of walking is provided by motor+reductor, once running into emergency case will run out of steam and cannot walk, if can not drag it to platform position of readiness in addition by external force in time, carry out emergency treatment, will cause molten steel solidification or other afunction ,Gei steel mill to cause tremendous economic loss.In the very spacious steel mill in some ground space positions, can rapidly its level be hauled out and be carried out respective handling by towing vehicle; And in the steel mill of some ground space location comparison compactnesses, the enough places that do not have level to haul out, at this moment just need a kind of suitable device as intermediary, the Y-direction power of crane or driving is converted into X-direction power, by steel rope, connects first engineering truck to be hauled out and carry out again respective handling beyond steel structure platform.
Processing method when at present, accident appears in engineering truck is: the long steel pipe of burn-oning on two track tops is realized Y-direction power to the conversion of X-direction power temporarily.Owing to belonging to high-temperature area herein, workman herein operation is temporarily very dangerous.In addition, the steel pipe of interim welding is difficult to guarantee that the hanger with engineering truck unifies absolute altitude, causes resistance to strengthen, and often occurs that steel rope is pulled off or steel pipe collapses situation about falling, quite dangerous.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of urgent hitch structure, avoided operating personal inconsistent in the danger of high-temperature area operation and the absolute altitude of the steel pipe of interim welding and the hanger of engineering truck, cause resistance to strengthen, occur that steel rope is pulled off or steel pipe collapses situation about falling.
In order to achieve the above object, the technical scheme that the utility model is taked is:
A kind of urgent hitch structure, comprise traction base 2, holding-down bolt 1 is fixed on ground by traction base 2, and one end of connecting rod 4 is connected by adapter shaft 3 with drawing between base 2, between the other end of connecting rod 4 and rotary pulley 5, by wheel shaft 6, be connected, on rotary pulley 5, be provided with steel rope 7.
The length L of described connecting rod 4 is determined by the height of hanger on engineering truck, guarantees that the bottom surface of hanger and rotary pulley 5 is on same level height.
Technique effect of the present utility model is:
Solved the technical matters that cannot steadily haul out in time when steel mill's engineering truck runs into emergency case and runs out of steam, before engineering truck place in operation, urgent draw gear installed to suitable position and adjust height.The utility model can guarantee that steel mill's engineering truck runs into and when emergency case runs out of steam, utilize crane or driving in time they steadily to be hauled out and carry out repair and maintenance processing, reduce the unnecessary economic loss of steel mill.Avoided operating personal inconsistent in the danger of high-temperature area operation and the absolute altitude of the steel pipe of interim welding and the hanger of engineering truck simultaneously, caused resistance increasing, occurred that steel rope is pulled off or steel pipe collapses situation about falling.
Accompanying drawing explanation
Fig. 1 is the utility model work schematic diagram.
Fig. 2 is the utility model standby schematic diagram at ordinary times.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
See figures.1.and.2, a kind of urgent hitch structure, comprise traction base 2, holding-down bolt 1 is fixed on ground by traction base 2, one end of connecting rod 4 is connected by adapter shaft 3 between base 2 with traction, between the other end of connecting rod 4 and rotary pulley 5, by wheel shaft 6, be connected, on rotary pulley 5, be provided with steel rope 7.
The length L of described connecting rod 4 is determined by the height of hanger on engineering truck, guarantees that the bottom surface of hanger and rotary pulley 5, on same level height, is conducive to the transmission of propulsive effort.
Principle of work of the present utility model is:
As depicted in figs. 1 and 2, when running into emergency case, engineering truck runs out of steam cannot autonomous time, two ends around the steel rope 7 on urgent draw gear rotary pulley 5 are connected with the suspension hook of driving or crane and the hanger of engineering truck respectively, driving or crane provide suitable propulsive effort to carry out repair and maintenance operation beyond engineering truck is steadily dragged to steel structure platform, reduce unnecessary economic loss, guarantee the normal production of steel mill.
The parts that the utility model does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
