Abstract
The utility model relates to a lever-type pedal jack. The lever-type pedal jack comprises a curved surface supporting plate, a connection shaft, a supporting point frame, a pedal plate, a connection rod and a base, wherein the pedal plate is fixed to one end of the connection rod, the curved surface supporting plate is fixed to the other end of the connection rod, the connection rod is fixed to the supporting point frame through the connection shaft, and the base is fixedly connected with the bottom of the supporting point frame. The lever-type pedal jack has the advantages of being suitable for narrow and small operating environments, suitable for replacement, installation, blowing and other operations of various valves and pipelines, simple in structure, easy to manufacture and install and convenient to use, reducing labor difficulty, saving maintenance time, relieving labor intensity, improving operation safety and providing effective safety protection against mechanical injury.
Description
Technical field
The utility model relates to a kind of lever pedal jack.
Background technology
Converter installation is formed a complete set of and is formed by plurality of devices, and device category is many, and particularly all kinds of valve pipes are covered with therebetween on each layer of platform of converter, repair converter day, periodical repair and break service work frequent.As desulfurization periodical repair, day repair in operation, the pipeline valve of all calcium powders, coal dust all needs dismounting, purges.Large valve weighs seven, 80 jin.And narrow space, height institute is limit, and apparatus for hoisting cannot be set, and can only lean on crowbar, people to lift and solve a lifting difficult problem, and operator does not originally directly play waist narrow space Rigen, the personal injury accident such as very easily have one's foot squashed, sway one's hips, this operation makes operator's headache.For the more present situation of this narrow restricted clearance of converter, be badly in need of a kind of instrument addressing the above problem.Alleviate worker's manual labor, stop all kinds of personal injury accidents and occur.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of lever pedal jack, and floor area is little, be applicable to installing space narrow and small, weight-lifting equipment and anomaly platform cannot be installed apart from circlet border, reduce task difficulty, avoid the generation of work accident.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of lever pedal jack, comprise curved surface supporting plate, adapter shaft, fulcrum frame, stretcher, connecting rod, base, connecting rod one end is fixed with stretcher, and the other end is fixed with curved surface supporting plate, connecting rod is fixed on fulcrum frame by adapter shaft, and base is fixedly connected with fulcrum frame bottom.
Described curved surface supporting plate is fixedly connected with by fastener with connecting rod.
Described fulcrum frame is two, and adapter shaft is through two fulcrum framves and be located at two connecting rods fulcrum frame, and connecting rod rotates take adapter shaft as fulcrum.
Compared with prior art, the beneficial effects of the utility model are:
Be applicable to narrow and small operating environment, be applicable to an operation such as all kinds of valves, pipeline replacing, installation, purging; Simple in structure, be easy to make, install, easy to use, reduced work difficulty, saved the repair time, alleviated labour intensity, improved processing safety, to mechanical wounding, provide actv. safety control.

Fig. 2 is block diagram of the present utility model.
In figure: 1-base 2-fulcrum frame 3-adapter shaft 4-connecting rod 5-curved surface supporting plate 6-stretcher 7-fastener.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of lever pedal jack, comprises curved surface supporting plate, adapter shaft, fulcrum frame, stretcher, connecting rod, base, connecting rod one end is fixed with stretcher, the other end is fixed with curved surface supporting plate, and connecting rod is fixed on fulcrum frame by adapter shaft, and base is fixedly connected with fulcrum frame bottom.Described curved surface supporting plate is fixedly connected with by fastener with connecting rod.Curved surface supporting plate is arcuate structure, and concave surface and valve or pipeline match.Curved surface supporting plate adopts the mode of fastener to be connected with connecting rod, easy disassembly, and the curved surface supporting plate of replaceable different curvature, to meet the needs of valve or pipeline.
Described fulcrum frame is two, and adapter shaft is through two fulcrum framves and be located at two connecting rods fulcrum frame, and connecting rod rotates take adapter shaft as fulcrum.
During use, curved surface supporting plate is placed on to the valve or the pipeline bottom that are replaced or overhaul, manually firmly slams stretcher, connecting rod is take adapter shaft as fulcrum, the perk of curved surface supporting plate, by valve or pipeline perk, completes valve Bolt dismantling and installation, and people of operator just can carry out this operation; Dismantled after bolt with flange, by the holder of Jack curved surface supporting plate, in the bottom of valve, stretcher steps down in operator's underfooting, and the flange port that staggers, purges, and after purging, flange is aligned, and carries out bolted.This tool construction is simple, convenient and practical, improves safety, has saved the repair time, guarantees production direct motion.
Jack utilizes lever principle to complete all kinds of valves on all kinds of platforms of converter under the condition without weight-lifting equipment, to carry out the upkeep operation that completes safely and fast.
The utility model is applicable to narrow and small operating environment, is applicable to an operation such as all kinds of valves, pipeline replacing, installation, purging; Simple in structure, be easy to make, install, easy to use, reduced work difficulty, saved the repair time, alleviated labour intensity, improved processing safety, to mechanical wounding, provide actv. safety control.
