Description
Technical field
This practicality is related to a kind of engineering machinery, more particularly to a kind of hydraulic workbench with safety guard.
Background technology
Hydraulic workbench can require the hoistable platform of special requirement customized according to user.Applied to factory, automated warehouse,
Parking lot, municipal administration, harbour, building, finishing, logistics, electric power, traffic, oil, chemical industry, hotel, gymnasium, industrial and mineral, enterprise etc.
Work high above the ground and maintenance.Hoistable platform jacking system, it is to lean on hydraulic-driven, therefore is referred to as hydraulic workbench.Most of types
Using unidirectional oil cylinder, during rising, vane pump exports hydraulic oil and enters oil cylinder bottom by a series of control valves and pipeline, promotes oily
Cylinder is up, drives platform raising；During decline, vane pump stops, and control valve opens leakage passage, and platform is slow under Gravitative Loads
Decline, the hydraulic oil in oil cylinder is extruded draining.
To make weight smooth decreasing, brake safe is reliable, and balanced valve is set on oil return line, balanced loop, keeps pressure,
Decrease speed is not changed by weight, by throttle valve adjustment flow, control lifting speed.To make brake safe reliable, prevent
It is unexpected, increase hydraulic control one-way valve, i.e. hydraulic lock, ensureing can safe self-locking when hydraulic line surprisingly bursts.Hydraulic workbench
Suitable for automobile, container, Making mold, timber is processed, and all types of industries enterprise and the production lines such as chemical industry is filling, can be equipped with
All kinds of table top forms（Such as ball, roller, rotating disk, turn to, tumble, stretch）, coordinate various control modes（Transfer, linkage, prevent
It is quick-fried）, have the characteristics that lifting exactly, frequent starting, loading capacity are big, it is difficult effectively to solve all kinds of lift works in industrial enterprise
Point, make production operation free and relaxed.
Current existing hydraulic workbench, during workbench declines, when having foreign matter below workbench,
Because workbench does not have protection device in itself, workbench can be impinged upon on foreign matter, cause foreign matter and workbench in itself
Damage.The transmission system of workbench still will not be stopped after shock, may proceed to discharge chain, make the gravity of workbench
It is entirely applied on foreign matter, causes to will also result in workbench inclination while foreign matter and device damage, on workbench
The life security of operating personnel threatens.Needed workbench liter when being cleared up after shock foreign matter again
After rising, then cleared up, wasted time and energy.
Therefore it is simple in construction to produce one kind, easily implements, high safety, can effectively solve hydraulic workbench and decline
During hit foreign matter the hydraulic workbench with safety guard, there are wide market prospects.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of simple in construction, easily implements, high safety can
The hydraulic workbench with safety guard of foreign matter is hit effectively to solve hydraulic workbench during decline.
What scheme of the present utility model was realized in：A kind of hydraulic workbench with safety guard, including
Both sides are provided with the framework of crossbeam, are provided with oil cylinder on each crossbeam, sliding bar is connected with the top of oil cylinder, in sliding bar
Above be symmetrically arranged with gear, chain is set with gear, the both ends of chain are connected with crossbeam and workbench respectively, institute
The workbench bottom stated is provided with safety guard.
Described safety guard is made up of light projector and light-receiving device two parts, is connected between light projector and light-receiving device
There is safe light curtain, light projector and light-receiving device are arranged in parallel at the both ends of workbench bottom.
The direction that the installation direction of described crossbeam is installed with framework is mutually perpendicular to, installation direction and the horizontal plane phase of framework
Mutually vertical, crossbeam is connected to the middle part of frame facet by way of welding.
Described sliding bar bottom centre position is connected with the piston guide rod tip position of oil cylinder, and the both ends of sliding bar are equal
Assembly pulley is provided with, the lateral surface of assembly pulley is connected with frame facet, described assembly pulley at least 2 pulleys, in cunning
The top of lever is provided with two symmetrical gears, is set with chain on each gear, chain is by way of welding
It is symmetrically connected to the side of workbench, the installation direction of described workbench and framework is mutually perpendicular to.
The protection breadth of described light projector and light-receiving device is not less than the light of the width of workbench, light projector and light-receiving device
Distance between axles is 10mm.
The utility model has the positive effect that：First, simple in construction, the utility model passes through in workbench bottom
Position that both ends are parallel to each other sets the light projector of safe light curtain and the mode of light-receiving device to realize, relative to prior art, only
It is that workbench bottom adds safe light curtain, main body still retains original structure, therefore simple in construction；Secondly, it is easily real
Apply, safe light curtain is a kind of common photo-electric safety protection device, is readily available, and output end coordinates relay normally open contact to make
With the engineering staff for having certain electrically basis can complete wiring according to drawing, therefore easily implement；Again, high safety, can
Effectively to solve the accident generation that hydraulic workbench runs into foreign matter shock during decline, with safety guard
When hydraulic workbench is run, protection light curtain can be formed between the light projector and light-receiving device of safe light curtain, when workbench is under
When foreign matter is run into during drop blocking protection light curtain, light-receiving device can produce shielding signals, be transmitted to control circuit, disconnect transmission system
Power supply, the platform that is stopped continue to decline, and prevent equipment and foreign matter shock and the safety of Field Force.
