Abstract
The utility model discloses a draw arm hook, which relates to the machinery for loading and unloading a tank body to an automobile and comprises a large arm, a subframe and an oil cylinder. The essential technology is that the inside of the large arm is provided with a cavity, two sides of the large arm are provided with sliding chutes, a lifting oil cylinder is arranged at the lower end of the cavity of the large arm, and a wheel shaft is arranged at the top of a piston rod of the lifting oil cylinder; a draw hook is embedded into the sliding chute, one end of the draw hook is fixed on a chain, and the other end of the chain rounds the wheel shaft and then is fixed on the large arm, and the lower end of the large arm is connected to one end of the subframe by a rotating shaft; and a tilting oil cylinder is arranged at the middle position of the subframe, and the other end of the tilting oil cylinder is hinged to the middle position of the tilting oil cylinder. The draw arm hook has simple structure, lower cost and low requirement on working pressure of a hydraulic system.
Description
(1) technical field:
A kind of torque arm hook relates to a kind of machinery that makes the casing getting on-off automobile.
(2) background technology:
The torque arm hook that uses is contained on the automobile now, makes the casing getting on-off automobile.The big arm of torque arm hook is a foldable structure, need unfold when promoting or putting down casing or folding big arm, because unreasonable structure causes the operation pressure of hydraulic efficiency pressure system higher.Also there is complex structure in this torque arm hook, the cost problem of higher.
(3) summary of the invention:
Problem to be solved in the utility model be exactly to provide at above deficiency a kind of simple in structure, cost is lower, and hydraulic system working pressure is required low torque arm hook.Its technical scheme is as follows:
It comprises big arm, subframe and oil cylinder.Its gordian technique is that the inside of big arm is cavity, both sides have chute, lower end at big arm cavity is provided with elevating ram, piston rod part at elevating ram is provided with wheel shaft, is embedded in drag hook at chute, and an end of drag hook is fixed on the chain, the chain other end is fixed on the big arm after walking around wheel shaft, big arm lower end is connected an end of subframe by rotating shaft, is provided with dump ram at the medium position of subframe, and the other end of dump ram is hinged on the medium position of big arm.
Compared with prior art the utlity model has following beneficial effect:
1, simple in structure, cost is lower;
2, owing to the change of force way, hydraulic system working pressure is lower, reliable operation;
3, production technology is simple;
4,, be convenient to the repair and maintenance of equipment owing to above advantage.
(4) description of drawings:
Fig. 1 is the utility model structural representation.
(5) specific embodiment:
Referring to accompanying drawing, the utility model comprises big arm 1, subframe 3 and oil cylinder.Its gordian technique is that the inside of big arm 1 is cavity, both sides have chute 6, lower end at big arm cavity is provided with elevating ram 7, piston rod part at elevating ram 7 is provided with wheel shaft 2, is embedded in drag hook 8 at chute 6, and an end of drag hook 8 is fixed on the chain 9, chain 9 other ends are fixed on the big arm 1 after walking around wheel shaft 2, big arm 1 lower end is connected an end of subframe 3 by rotating shaft 5, is provided with dump ram 4 at the medium position of subframe 3, and the other end of dump ram 4 is hinged on the medium position of big arm 1.
Its working process is:
When drawing case to get on the bus:
1. give the rodless cavity fuel feeding of dump ram 4, big arm 1 is lifted;
2. give the rod chamber fuel feeding of elevating ram 7, make drag hook slide to the bottom for 8 times, mobile automobile makes drag hook 8 hold railway carriage;
3. give the rodless cavity fuel feeding of elevating ram 7, make drag hook 8 rise to certain altitude;
4. give the rod chamber fuel feeding of dump ram 4, make big arm 1 return back to horizontality;
5. continue to give the rodless cavity fuel feeding of elevating ram 7, make casing arrive desired location on the automobile.
When putting down casing:
1. give the rodless cavity fuel feeding of dump ram 4, big arm 1 is lifted;
2. give the rod chamber fuel feeding of elevating ram 7, make drag hook slide to the bottom for 8 times, casing is put to ground.
