Description
Technical field
The utility model relates to a kind of device being applied to Bolt dismantling in mining operation field, is specifically related to a kind of air leg pneumtic impact wrench.This air leg pneumtic impact wrench be mainly used in mine main equipment large size nut, corrosion nut, be positioned at overhead higher nut dismounting.
Background technology
Pneumatic impact spanner is the efficient mechanical instrument of dismounting screw nut, and it all has purposes widely in industries such as oil, chemical industry, railway, bridge, automobile, electric power, mine, boats and ships, buildings.In machinery manufacturing industry, on general assembly line, except each part, maximum be exactly screw bolt and nut.The quality of a product quality to a great extent, does not lie in the quality of each part, and is the quality of assembling.
Current domestic application more widely pneumatic impact spanner is divided into and is generally divided into two classes, and a class is impact wrench routinely, and a class is pulse pneumatic spanner, and both differences are, the former can not determine moment of torsion, and the latter can but equipment price is expensive.The assembly shop pneumatic impact spanner that often service efficiency is high of integrated mill carries out the work of stubborn bolt, but moment needed for the bolt of different size, different parts is different, qualified in order to ensure the moment tighted a bolt, after pneumatic impact spanner is tightened, also need special messenger with the tight bolt of common wrench.Often final workman puts forth one's strength excessive, is greater than required screw-down torque.So not only waste manpower, can't ensure the uniformity of moment, the bolt that relative screw-down torque is little just easily loosens, and there is potential safety hazard.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is: provide that a kind of structure is simple, reasonable in design, moment of torsion is enough, easy to operate, greatly can reduce labor strength and can the air leg pneumtic impact wrench of difficult tightening nut in solution work quickly and easily.
To achieve these goals, the utility model adopts following technical scheme:
A kind of air leg pneumtic impact wrench, described air leg pneumtic impact wrench comprises air leg assembly, flow speed control valve assembly, reversal valve, pneumatic impact wrench assembly, shut-off valve assemblies and inlet suction port; Described flow speed control valve assembly respectively with described reversal valve and described inlet suction port in mating connection; Wherein, described reversal valve is for controlling the forward and reverse of described pneumatic impact wrench assembly; Described pneumatic impact wrench is arranged on the top of described air leg assembly; Described inlet suction port is connected for providing power to described air leg pneumtic impact wrench with air pump; Described air leg assembly comprises top fork and for regulating the air leg elevating mechanism of air leg component height, described top fork is arranged at the bottom of air leg assembly, and described air leg elevating mechanism is connected with described top fork.
Further improvement as such scheme: described inlet suction port is also provided with the barometer for detecting Pneumatic pressure.
Further improvement as such scheme: described air leg pneumtic impact wrench also comprises gas leakage prior-warning device, described gas leakage prior-warning device is connected with described barometer.
Further improvement as such scheme: described air leg lifting structure is for comprising telescopic bar, described expansion link is set with is formed by rod base, outer tube, more piece inner sleeve, pipe cap, the lower end cap often saving inner sleeve lower end is provided with hold-down bolt and the sealing gasket of band pore, often saves the upper plug head having interior band sealing gasket outside inner sleeve upper end.
Further improvement as such scheme: described top fork is triangular pyramid type.
Compared with dismantling the instrument of nut in prior art, the air leg pneumtic impact wrench tool that the utility model adopts has the following advantages:
(1) structure is simple, easy to carry;
(2) reasonable in design, moment of torsion is enough, can for the large size nut of the medium-and-large-sized equipment of the complicated environment for use in mine, corrosion nut, be positioned at overhead higher nut and carry out degree of tightness quickly and easily.
(3) labour intensity of workman can be reduced widely, and work task efficiency improves widely.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model air leg pneumtic impact wrench.
Detailed description of the invention
Be described in detail below in conjunction with the structure of accompanying drawing 1 pair of the utility model air leg pneumtic impact wrench and using method thereof.
A kind of air leg pneumtic impact wrench, described air leg pneumtic impact wrench comprises air leg assembly 1, flow speed control valve assembly 2, reversal valve 3, pneumatic impact wrench assembly 4, shut-off valve assemblies 5 and inlet suction port 6; Described flow speed control valve assembly respectively with described reversal valve and described inlet suction port in mating connection; Wherein, described reversal valve is for controlling the forward and reverse of described pneumatic impact wrench assembly; Described pneumatic impact wrench is arranged on the top of described air leg assembly; Described inlet suction port is connected for providing power to described air leg pneumtic impact wrench with air pump; Described air leg assembly comprises top fork and for regulating the air leg elevating mechanism of air leg component height, described top fork is arranged at the bottom of air leg assembly, and described air leg elevating mechanism is connected with described top fork.Described inlet suction port 6 is also provided with the barometer for detecting Pneumatic pressure.Described air leg pneumtic impact wrench also comprises gas leakage prior-warning device, and described gas leakage prior-warning device is connected with described barometer.Described air leg lifting structure is for comprising telescopic bar, described expansion link is set with is formed by rod base, outer tube, more piece inner sleeve, pipe cap, the lower end cap often saving inner sleeve lower end is provided with hold-down bolt and the sealing gasket of band pore, often saves the upper plug head having interior band sealing gasket outside inner sleeve upper end.Described top fork is triangular pyramid type.
The using method of this air leg pneumtic impact wrench is as follows:
(1) top of air leg component bottom fork is inserted ground to be fixed, press direction switch lock, (turn clockwise adjustment pneumatic wrench height direction switch, and air leg rises; Be rotated counterclockwise direction switch, air leg declines), after pneumatic wrench being put into working position, rotation and lifting switch is to middle latched position;
(2) pneumatic wrench direction of rotation selected by rotary pneumatic trigger reversal valve, and wherein dextrorotation goes to the rightest, and pneumatic wrench reverses, and is rotated counterclockwise to the most left, and pneumatic wrench rotates forward, and presses pneumatic wrench switch, pneumatic wrench work, starts to carry out tightening nut;
