Abstract
The utility model relates to a hydraulic pressure balance crane, which comprises a hydro-cylinder, a hydraulic valve assembly, an oil pump assembly, a lazy arm seat and a lazy arm. The upper end of the lazy arm seat is provided with the lazy arm, the hydro-cylinder is arranged between the lazy arm seat and a supporting seat, the upper side of the supporting seat is provided with an electric box, one side of the hydro-cylinder is connected with the hydraulic valve assembly, and the ends of the hydraulic valve assembly are provided with safe overflow valves. Two magnetic exchange valves are arranged inside the hydraulic valve assembly, and one sides of the magnetic exchange valves are provided with one-way throttle valves. The hydraulic pressure balance crane has the advantages of being convenient in operation and beneficial to the adjustment of the lifting speed by adopting a two-path oil discharge. By setting the safe valves, the balance crane can not lift due to the overflow opened by the safe valves when the lifted weight exceeds a predetermined weight, and the location of an extreme position is realized by depending on the route of the hydro-cylinder. Besides, only a sealing element is needed to be changed after the abrasion of the balance crane, thereby saving large amounts of maintenance costs.
Description
Technical field
The utility model relates to the lifting appliance technology, relates in particular to a kind of hydro-cushion that has overload protection and help regulating rising or falling speed and hangs.
Background technology
Balance crane claims power-assisted manipulator, manual transfer machine again, is a kind of power assistive device of laborsaving operation when being used for material handling, is particularly useful for the application scenario that some has accurate location and assembling action request.It is the equilibrium principle of application of force dexterously, makes workpiece form a kind of agravicization quick condition aloft.Existing balance crane mostly is mechanical rotation formula balance crane greatly, promptly drives worm gear by worm screw, drives screw mandrel by screw again and carries out transmission, and its weak point is that rotating speed can't change, and only has a kind of fixedly running velocity and relies on travel switch spacing; When transshipping, hoisting heavy lacks necessary safety method.In addition, the accessory that must more renew after the mechanical part wearing and tearing could be repaired, and the expense of aftermarket attachment is higher.
The utility model content
At above defective, the hydro-cushion that the utility model provides a kind of easy to operate, speed of helping regulating rising or falling speed, have overload protection function, need not to be provided with travel switch, maintenance cost is lower is hung, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of hydro-cushion is hung, comprise oil cylinder, hydraulic valve assembly, oil pump assembly, arm seat and arm, arm is installed in arm seat upper end, oil cylinder is installed between arm seat and the base for supporting, the base for supporting upside is provided with electric box, described oil cylinder one side connects hydraulic valve assembly, and the hydraulic valve assembly end is provided with safety overflow valve.Described hydraulic valve assembly inside is provided with two solenoid directional control valves, and solenoid directional control valve one side is provided with one-way throttle valve.
The beneficial effect that hydro-cushion described in the utility model is hung is: easy to operate, and adopt the binary channel oil extraction to help realizing the speed adjusting of rising or falling speed; By safety valve is set, when surpassing specified hoisting weight, this safety valve is opened overflow can't lift by crane it, the location that the stroke of dependence oil cylinder self is realized end position; In addition, after wearing and tearing, only need change sealing member and get final product, therefore save a large amount of maintenance costs; Can be applicable to the lifting appliance of lifting porter part on machine shop, foundry shop, the flow process line, power of motor is less, has certain energy-saving effect.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the external structure scheme drawing that the described hydro-cushion of the utility model embodiment is hung;
Fig. 2 is that the hydraulic pressure that the described hydro-cushion of the utility model embodiment is hung is formed principle schematic;
Fig. 3 is the electrical principle scheme drawing that the described hydro-cushion of the utility model embodiment is hung.
Among the figure:
1, oil cylinder; 2, hydraulic valve assembly; 3, oil pump assembly; 4, safety overflow valve; 5, electrical motor; 6, arm seat; 7, electric box; 8, base for supporting; 9, connecting rod; 10, arm; 11, suspension hook; 12, one-way throttle valve; 13, solenoid directional control valve one; 14, solenoid directional control valve two; 15, flow regulating valve.
The specific embodiment
As Figure 1-3, the described hydro-cushion of the utility model embodiment is hung, comprise oil cylinder 1, hydraulic valve assembly 2, oil pump assembly 3, arm seat 6 and arm 10, described oil cylinder 1 is installed between arm seat 6 and the base for supporting 8, base for supporting 8 upsides are provided with electric box 7, are positioned at electric box 7 tops and electrical motor 5 are set and connect oil pump assembly 3; Described oil cylinder 1 one sides connect hydraulic valve assembly 2, described hydraulic valve assembly 2 is that solenoid directional control valve 1 is formed with solenoid directional control valve 2 14 by safety overflow valve 4, flow regulating valve 15, two solenoid directional control valves, two solenoid directional control valves are arranged at hydraulic valve assembly 2 inner both sides respectively, solenoid directional control valve one end is provided with one-way throttle valve 12, and hydraulic valve assembly 2 ends are provided with safety overflow valve 4; The arm 10 that has connecting rod 9 is installed in described arm seat 6 upper ends, and the end of this arm 10 is provided with suspension hook 11.In the lifting process, when the needs fast lifting, the electromagnet of right side solenoid directional control valve 1 has electricity, and the fluid in the oil cylinder annular chamber enters solenoid directional control valve 1 through one-way throttle valve 12 and flows back to fuel tank realization quick action; When needs at a slow speed during lifting, the electromagnet of left side solenoid directional control valve 2 14 has electricity and oil cylinder epicoele fluid to enter flow regulating valve 15 through one-way throttle valve 12, flows back to fuel tank through solenoid directional control valve 2 14 again and realizes action at a slow speed; When the weight of hoisting heavy surpass hydro-cushion hang specified hoisting weight 10% the time, safety overflow valve 4 is opened overflows, thereby can not the be sling mechanism of preventive device of weight is not destroyed; The end position that helps relying on the clamping of oil cylinder piston and oil cylinder head rear side housing to come limiting balance to hang does not need travel switch to cut off the end position that electric current comes limiting balance to hang, thereby can make position limiting structure simple and reliable; In addition, after wearing and tearing, only need change sealing member and get final product, therefore save a large amount of maintenance costs.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
