The specific embodiment
Now the invention will be further described by reference to the accompanying drawings.
With reference to figure 1 and Fig. 2, clamp hoist of the present invention comprises clamping limb 101, limit laminate 102, switch circuit controller 109, connection structure 111, hydraulic efficiency pressure system and electric control system; Wherein, described hydraulic efficiency pressure system comprises fuel tank 104, hydraulic cylinder piston 103, hydraulic actuating cylinder, and described electric control system comprises number of plies select switch 108, electromagnetic valve 106 and travel switch 107; The bottom of described hydraulic cylinder piston 103 is connected with described limit laminate 102, and described limit laminate 102 is positioned at outside described hydraulic actuating cylinder; Described clamping limb 101 connects with the bottom of connection structure 111, the upper end of described connection structure 111 includes hoisting axis 112, the top of described switch circuit controller 109 is connected with described hoisting axis 112, the bottom is connected with hydraulic actuating cylinder, when the suspender rising, when switch circuit controller is in off-state, clamping limb 101 closures are clamped convection-plate, when the suspender whereabouts, when switch circuit controller was in closure state, clamping limb 101 unclamped; Described number of plies select switch 108, travel switch 107 are connected with electromagnetic valve 106, are used for the key-course numerical digit and put, and when the position consistency of the position of number of plies select switch 108 and travel switch 107, electromagnetic valve 106 must be electric, hydraulic cylinder piston 103 stop motions.
The below is further described the various piece of clamp hoist of the present invention.
Described clamping limb 101 is used for the clamp convection-plate.In the present embodiment, described clamping limb 101 has two, 101 one-tenth semicircular arcs of each clamping limb, thus identical with the arc surface of convection-plate.Opening or closing of described clamping limb 101 controlled by switch circuit controller 109 and fixture lifting situation.When switch circuit controller 109 was closed, clamping limb 101 opened, when switch circuit controller 109 disengagements, when fixture rises, and clamping limb 101 closures, thus clamp convection-plate.
Described hydraulic cylinder piston 103 is used for driving the movement of the limit laminate 102 that is positioned at its bottom, and then realizes the control to limit laminate 102 present positions.
Described fuel tank 104 is used for storage hydraulic oil.The hydraulic oil of storing in fuel tank 104 can promote the movement of described hydraulic cylinder piston 103 under Action of Gravity Field.
Described hydraulic actuating cylinder comprises hydraulic actuating cylinder rod chamber 105 and hydraulic actuating cylinder rodless cavity 110, and described hydraulic actuating cylinder rod chamber 105 is separated by hydraulic cylinder piston 103 mutually with hydraulic actuating cylinder rodless cavity 110.Link together by two position four-way valves between hydraulic actuating cylinder rodless cavity 110, rod chamber 105 and fuel tank 104.When hydraulic cylinder piston 103 descends, rodless cavity 110 beginning oil-feeds, rod chamber 105 oil extractions, because two chamber volume difference are large, unnecessary oil enters fuel tank 104, and electromagnetic valve gets electricly when reaching desired location, and hydraulic oil stops flowing, oil in rod chamber 105 and fuel tank 104 all is in static state, keeps original state.
Described electromagnetic valve 106 is used for whether hydraulic cylinder piston 103 is moved controlling.When described electromagnetic valve 106 was in power failure state, hydraulic cylinder piston 103 can normally move, when its be in during electricity condition, hydraulic cylinder piston 103 is locked, stops mobile.Whether electromagnetic valve 106 is in to get electricity condition, is subject to the control of number of plies select switch 108 and travel switch 107, and when the position consistency of the position of number of plies select switch 108 and travel switch 107, electromagnetic valve 106 must be electric, hydraulic cylinder piston 103 stop motions.
Described travel switch 107 has many grades of master cocies, and the gear number of described master cock is relevant with the number of the maximum convection-plate of institute's energy clamping.In the present embodiment, clamp hoist of the present invention at most can four convection-plates of clamping, therefore described travel switch 107 has the fourth gear master cock, four positions of corresponding limit laminate 102 respectively, described four positions of described limit laminate 102 respectively the convection-plate of the corresponding clamp of wanting one, two, three, four these four kinds of different situations are arranged.But in other embodiments, if can clamping the number of convection-plate change, the gear number of the master cock of travel switch 107 also needs correspondence to change.
It is more than the explanation to clamp hoist of the present invention.Below in conjunction with concrete example, the working process of this suspender is described.
In the one action process, when selecting a convection-plate of lifting, the operative employee chooses travel switch 7 on " 1. ", after limit laminate 102 drops to bottom (position that is corresponding a slice convection current table), electromagnetic valve 106 gets electric, hydraulic closure system, and clamping limb 101 falls, the opening of its bottom amplifies the loose hook at two ends, lifts by crane a convection-plate.When the convection-plate number that will lift changed, the button of travel switch 7 changed, and corresponding adjustment is also done in the position of line laminate 102, thereby realized the lifting to the convection-plate of respective number.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described.Although with reference to embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is modified or is equal to replacement, do not break away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
