Description
Technical field
The present invention relates to a kind of rod nut tightening devices, belong to fastener installation tool technical field.
Background technique
The application range of heavy centrifugal multistage pump multiple centrifugal pump is each throughout coal mine, petroleum, steel mill, national defence, agricultural and Chemical Manufacture etc.
Field, usage amount are very big.It extracts medium and contains a large amount of solid particle, cause the service life of pump very low, general 2 ~ 3
The moon will carry out large repairs.By taking heavy type centrifugal multistage pump multiple centrifugal pump most common in mine as an example, pressure when work in the pump housing is very big, in order to
So that each shaft part is closely linked together, needs to be bolted using the very big rod of specification required when pump housing work could be provided
Preload force request.When being dismounted with traditional manpower method, not only large labor intensity, operating efficiency is low, at high cost, and
Due to the influence of high vibration, in the construction process it is also possible to the components that damage is adjoined, or even influence and destruction were tied originally
The mechanical balance of structure；It is also difficult to accurately control assembly torque according to design requirement simultaneously.
In order to improve the speed of centrifugal multistage pump multiple centrifugal pump assembly and disassembly, pump maintenance and service time are reduced, and control bolt
The pretightning force of connection wants to reach certain job requirement, and worker is freed from high-intensitive manual labor, it is desirable that
Design and produce it is a kind of suitable for centrifugal multistage pump multiple centrifugal pump rod be bolted this special construction tightening with disassembly with suit
It sets.
Since centrifugal multistage pump multiple centrifugal pump assumes responsibility for main draining task in mine, longevity of service, bad environments, and be discharged
Solid particle contained in water quality is more, in addition flowing water washes away impeller and the very easy corrosion of guide vane and abrasion.In order to guarantee mine
The safety of well working environment has multiple water pumps to take turns to operate in general mine, and a large amount of water pump needs to overhaul.Rod bolt connects
The height that will whether reliably be directly related to the multistage centrifugal efficiency of pump is connect, guarantees that rod is bolted to improve the efficiency of loading and unloading
Reliability is necessarily required to the handling carried out using biggish fastening and dismounting force moment to centrifugal pump rod bolt.
The handling method of rod bolt mainly have manually handling, crane loaded and unloaded, electric device carry out handling and liquid
Pressure device is loaded and unloaded, and it is the best way that wherein hydraulic device, which carries out handling,.
Hydraulic spanner be widely used in the industrial country of the prosperity such as Japan, the U.S., Germany motor vehicle repair, shipbuilding,
The fields such as chemical industry, bridge, military project.Since the starting of development of industry in China is than later weak foundation, eighties of last century the eighties are arrived
Latter stage, formal beginning is just calculated in domestic hydraulic spanner research work.The hydraulic spanner price sold on the market now is very expensive,
Again because the design feature of multi-stage centrifugal pump, bolt are unevenly distributed, such spanner counter-force arm is not easy to find supporting point.
Summary of the invention
Present invention mainly solves the technical issues of: for the handling using crane progress rod nut main at present, no
Only low efficiency, and the problem that pretightning force is not easy to control, the present invention provides a kind of rod nut tightening devices.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention:
A kind of rod nut tightening device, including shell, the enclosure interior are provided with nut bore, and nut bore outer ring is
Gear, gear left side are connected with motor gearbox by driving wheel A, are connected by driving wheel B with mekydro on the right side of gear
It connects, motor gear passes through the spine inside axis and rocker arm by axis connection motor, mekydro by axis connection gear-box, gear-box
Wheel is connected, and driving pawl is provided on ratchet, and rocker arm connects connecting pin, and connecting pin is connected by piston rod with hydraulic cylinder,
Manual overvide is provided with above shell.
A kind of application method of rod nut tightening device is: nut being placed in nut bore, uplifting device is directed at spiral shell
Bolt engages driving wheel A with gear and motor gear by manual overvide, driving motor, and motor is driven by gear-box
Motor gear, motor gear are rotated by driving wheel A sliding tooth wheel, nut are screwed on bolt, after nut is screwed on, passes through hand
Dynamic control device makes driving wheel B be connected with mekydro and gear, and by Driven by Hydraulic Cylinder piston rod, piston rod passes through connection
Pin makes rocker arm move reciprocatingly, and rocker arm drives mekydro by axis, rotates gear by mekydro and driving wheel B, will
Nut is tightened.
The transmission gear A and transmission gear B can be moved up and down, and be controlled by manual overvide.
Gear-box is provided between the motor gear and motor.
The beneficial effects of the present invention are:
(1) two groups of devices are devised in the present invention, one group is nut mounting device, and another group is nut tightening device, spiral shell
Female mounting device is mutually nibbled by motor gear, driving wheel A, gear-box and motor form, driving wheel A with motor gear and nut bore
It closes, by motor driven motor gear, motor gear can complete the installation of nut, nut by driving wheel A driving nut bore
Device for screwing up is made of mekydro, driving wheel B, rocker arm and hydraulic device, so that rocker arm is moved reciprocatingly by hydraulic device,
And rocker arm is internally provided with ratchet and driving pawl, when moving reciprocatingly, mekydro then makes rotating motion rocker arm, passes through liquid
The effect of pressure device, mekydro drives nut bore, and nut is tightened, and by this two groups of devices, the peace of nut is can be achieved in the present invention
Two kinds of functions are filled and tightened, the installation effectiveness of rod nut is improved.
(2) driving wheel A and driving wheel B can be moved up and down in the present invention, and be controlled by control device, and nut peace is being carried out
When pretending industry, driving wheel A is meshed with motor gear and nut bore, and driving wheel B is motionless, there was only nut mounting device in device
Work, does not influence device for screwing up, and similarly, when device for screwing up works, driving wheel A is motionless, does not influence mounting device, two groups of device works
By the successive operation of control device when making, the working efficiency and work quality of device are improved, the service life of device is extended.
