Description
Technical field
The utility model relates to a kind of support leg mechanism, is specifically related to a kind of truck-mounted crane hydraulic control zip mode automatic turning support leg mechanism.
Background technology
Lorry-mounted crane is a kind of hoisting device hoisting operation part be arranged on goods carrying vehicle, be a kind of new and effective lifting transportation equipment integrating lifting, transport, quick with it, flexible, efficient, convenient and handling, transport the advantage that unites two into one and be familiar with by increasing user and accept.Lorry-mounted crane is widely used in the cargo handing of the industries such as communications and transportation, civil construction, electric power and shifts goods at a distance, and the amelioration product that with the addition of additional device is also widely used in the fields such as fire-fighting, army, no-dig technique operation and emergency dealing.
Lorry-mounted crane in working order under, need vertical leg to open, be supported in ground, ensure the stability of car body and the safety of work; After having worked, need supporting leg to regain completely, the safety zone under making loop wheel machine entirety be positioned at driving states, ensures the safety of driving.
Domestic Domestic Truck Mounted Hydraulic Crane, hoisting crane divides according to form, is mainly divided into straight arm type and folding-jib.No matter which kind of form, supporting leg form all manual overturning is main, uses the phoenix feathers and unicorn horns of automatic turning form.Manual overturning, time-consuming, effort, economic performance is not high, poor stability, and the most cost of domestic automatic turning mechanism is higher, and stability is not enough, and safety has much room for improvement, and cannot meet the operating needs of domestic correspondent; External lorry-mounted crane adopts the more of automatic turning mechanism, and technology is more domestic maturation also, but its high cost allows numerous domestic correspondent hang back.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of truck-mounted crane hydraulic control zip mode automatic turning support leg mechanism, supporting leg automatic turning, and structure is simple, and with low cost, stability and safety is high.
To achieve these goals, the technical solution adopted in the utility model is: a kind of truck-mounted crane hydraulic control zip mode automatic turning support leg mechanism, comprise vertical support oil cylinder and movable leg, movable leg active link is in the side of vertical support oil cylinder, the opposite side of vertical support oil cylinder is provided with latch, also comprise hydraulic pressure control, secondary cylinder, pulley and leaf chain, secondary cylinder is fixed on vertical support oil cylinder by fastener, pulley is connected on movable leg circular shaft, there is groove pulley border, leaf chain is arranged in the groove of pulley, leaf chain one end is fixed in movable leg by adjusting screw(rod), the other end is fixed on secondary cylinder piston rod top, secondary cylinder is connected with hydraulic pressure control.
Further, also comprise mechanical lock, mechanical lock is arranged on vertical support oil cylinder top.
Further, also comprise anti-mistake and turn over nylon cushion, anti-mistake turns over the side that nylon cushion is arranged on vertical support oil cylinder reverses direction.
The beneficial effects of the utility model are: vertical support oil cylinder is fixed in movable leg, form revolute pair, by being fixed on the secondary cylinder retraction of vertical support oil cylinder, under the connection function of leaf chain, drive vertical support oil cylinder to rotate in movable leg junction, when secondary cylinder is controlled to stretch by hydraulic pressure control, transmit pulling force by leaf chain, by vertical support oil cylinder pull-up, rotate along movable leg anchor shaft, realize automatic turning, structure is simple, be easy to operation, work is convenient; By fluid control, cost is low, and performance safety is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model supporting leg working state structure schematic diagram;
Fig. 3 is the utility model supporting leg rollover states structural representation;
In figure: 1. hydraulic pressure control, 2. vertical support oil cylinder, 3. adjusting screw(rod), 4. anti-mistake turns over nylon cushion, 5. latch, 6. mechanical lock, 7. movable leg, 8. secondary cylinder piston rod, 9. secondary cylinder, 10. fastener, 11. pulleys, 12. leaf chains.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, these truck-mounted crane hydraulic control zip mode automatic turning support leg mechanism, comprises vertical support oil cylinder 2 and movable leg 7, and movable leg 7 active link is in the side of vertical support oil cylinder 2, and vertical support oil cylinder 2 and movable leg 7 form revolute pair; The opposite side of vertical support oil cylinder 2 is provided with latch 5, and latch 5 plays the effect of restrictive axial movement; Also comprise hydraulic pressure control 1, secondary cylinder 9, pulley 11 and leaf chain 12, secondary cylinder 9 is fixed on vertical support oil cylinder 2 by fastener 10, pulley 11 is connected on movable leg 7 circular shaft, there is groove pulley 11 border, for the guide passage of leaf chain 12, leaf chain 12 is arranged in the groove of pulley 11, leaf chain 12 one end is fixed in movable leg 7 by adjusting screw(rod) 3, in working order, by regulating adjusting screw(rod) 3, can stretching leaf chain 12, ensure the stability of vertical support oil cylinder 2, the other end is fixed on secondary cylinder piston rod 8 top, and secondary cylinder 9 is connected with hydraulic pressure control 1.
Principle of work: under driving states, supporting leg is needed to turn to state as shown in Figure 3, power is provided by hydraulic pressure control 1, secondary cylinder piston rod 8 is impelled to reclaim gradually, because leaf chain 12 one end is fixed, and length is certain, vertical support oil cylinder 2 left-hand revolution under the pulling force effect of secondary cylinder piston rod 8, until secondary cylinder piston rod 8 reclaims completely, now vertical support oil cylinder 2 switching process is complete.
In order to improve safety performance of the present utility model, set up mechanical lock 6, mechanical lock 6 is arranged on vertical support oil cylinder 2 top, and vertical support oil cylinder 2 works and under driving states, all has mechanical lock 6 to be locked in movable leg 7.
Set up anti-mistake and turn over nylon cushion 4, anti-mistake turns over the side that nylon cushion 4 is arranged on vertical support oil cylinder 2 reverses direction, plays vertical support oil cylinder 2 and crosses the effect of turning over, improve job security of the present utility model.
