Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below Accompanying drawings and embodiments are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only To explain the present invention, it is not intended to limit the present invention.
As shown in Figure 1 to Figure 3, shock-proof spring component 11 is mainly by lower spring cup 19, upper spring seat 20,21 and of spring guide Damping spring 22 is constituted, and upper spring seat 20 is fixed on chassis, and the bottom of lower spring cup 19 is provided with ear mount 23, lower spring cup 19 Middle part is provided with through-hole 24, and fluted 25 are arranged on upper swing arm 9, and ear mount 23 is hinged on the cell wall of groove 25, spring guide 21 Top is hinged on upper spring seat 20, and bottom is inserted into through-hole 24, and damping spring 22 is sleeved on spring guide 21, damping 22 both ends of spring are mounted on lower spring cup 19 and upper spring seat 20, and the middle part of spring guide 21 is provided with upper limit gear 26, bullet The bottom of spring guide rod 21 is provided with lower limit gear 27.
Wherein, the middle part of lower spring cup 19 is horizontally arranged with square hole 28, and latch 29, latch 29 are provided in square hole 28 On be provided with long hole 30, be provided with latch segment 31 in long hole 30, latch 29 and latch segment 31 are used for fastening spring guide rod 21, lock The hydraulic shunt pump 32 for driving latch segment to move, the both ends point of hydraulic shunt pump 32 are additionally provided between tight block 31 and latch 29 It is not fixed on latch segment 31 and latch 29.The contact surface of latch segment 31, latch 29 and spring guide 21 is arcuate structure. The top of lower spring cup 19 is additionally provided with buffering apron 14, and buffering apron 14 is sleeved on spring guide 21.
At the middle part of spring guide, setting upper limit is kept off, and bottom is arranged lower limit and keeps off, to limited spring shock mitigation system The up and down range of damping.When lower spring cup impacts upper limit gear upwards to be set, buffering apron can slow down impact force.
Be provided with latch in the square hole of lower spring cup lateral arrangement, in latch on be provided with long hole, peace in long hole Equipped with latch segment, latch and locking sliding block are used for clamp springs guide rod, realize self-locking function, and latch, locking sliding block with The contact surface of spring guide is two circular arcs, locks the space formed between postlaminar part and locking sliding block and is equipped with hydraulic shunt pump, When the fluid pressure come from hydraulic pipe is low, there is no clamping force between latch and locking sliding block, at this time spring damper system It can work normally, be in damping working state;When the fluid pressure come from hydraulic pipe is high, latch and locking sliding block are just Spring guide can be held tightly, lock together spring guide and latch, locking sliding block and lower spring cup all, spring shock absorption system The elastic shock attenuation of system acts on failure, switchs to rigid support state.In this way for some liftable freight trucks, in loading platform When being in lifting work state, it is desirable that the loading platform of rise cannot have shaking by a relatively large margin, and vehicle must be in and park On-position.With the work of hydraulic pump, the fluid pressure in hydraulic system is in high pressure conditions, and the high pressure of liquid passes through at this time Fluid path intercommunication element is passed to hydraulic shunt pump, the outside output pressure of the piston guide rod at hydraulic shunt pump both ends, latch through hydraulic pipe Spring guide is held tightly with locking sliding block, is latched fastening system, and system is in the rigid support state of shock-absorbing failure.By above-mentioned Logic relationship analysis, as long as configuring the oil piping system of the hydraulic pipe of hydraulic shunt pump, required spring of walking according to the method described above Control conversion between locking rigid support state needed for damping working state and lifting process is automatically performed, and is not required to Want the control system outside plus.To significantly reduce the labor intensity of tally personnel, the work effect of tally operation is improved Rate.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modifications, equivalent replacements, and improvements etc., should all wrap within the scope of the present invention within mind and principle.
