The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As Fig. 1, Fig. 2, shown in Figure 3, the present invention is made of with the man-engine two large divisions who is installed on truck chassis 1 vehicle frame truck chassis 1, truck chassis 1 is selected east wind EQ1092 type for use, truck chassis 1 vehicle frame is provided with four fluid pressure type supporting legs 2, before equipment uses, four fluid pressure type supporting legs 2 outwards can be reached and stretch out downwards, make the running wheel built on stilts, also can increase the Area of bearing of vehicle frame simultaneously.The man-engine partly comprises main frame cushion cap 3, two gigs 4,5, suspension arm mechanism and luffing mechanisms, four suspention wireropes 6, cage 7, clump weights 8, plays hanging box 9 etc., main frame cushion cap 3 is installed on truck chassis 1 vehicle frame by the revolution supporting mechanism, by driver train relatively vehicle frame turn round, two gig 4,5, suspension arm mechanism and luffing mechanism, clump weights 8 are installed on the main frame cushion cap 3, four suspention wireropes 6 pass through the leading sheave support of suspension arm mechanism, and the two ends of wirerope are connected with two gigs 4,5 with cage respectively.Position shown in Fig. 1 suspension arm mechanism dotted line and the solid line is respectively two positions in the starting point elevation angle and the terminal point elevation angle of arm luffing.
The revolution supporting mechanism of man-engine's main frame cushion cap 3 adopts lifting construction machinery and equipment outer race commonly used to be connected with work cushion cap 3 with bolt, toothed in and the chassis frame bolt together, be provided with the version of rolling body between the inner and outer race.Man-engine's load acts on vertical load, horizontal load and the capsizing moment of work cushion cap 3 and passes to chassis frame by outer race, rolling body and the interior seat commentaries on classics of revolution support.The rotary drive mechanism of main frame cushion cap 3 adopts by the buncher Drive pinion type of drive that is meshed with gear ring on the revolution support race, inner, miniature gears both can be around the axis rotation of self, again can be around the revolution of work cushion cap 3 line of centerss, work cushion cap 3 turns round with regard to relative chassis frame when driver train is worked.Because this part adopts known common structure, therefore do not carry out the accompanying drawing signal.
Referring to Fig. 4; two gigs 4,5 that are installed in side by side on the main frame cushion cap 3 all select for use double-cable type gig and two spool type take-up device to combine; the Tirak XD820P type gig that the double-cable type gig selects for use Da Ketai Tractel group Germany Grielzug company to produce has degradation safety protection function under brake, overload protection, overspeed protection safety lock, the manual safety.Two spool type take-up devices select for use have the rope arranging automatically device, wirerope is locking and terminal detects the matured product of fender guard function; should be different from traditional winch cylinder by automatically two spool type take-up devices; belong to towed winch; wirerope on take-up device reel is the state of not stressing, and increased the service life of wirerope widely.
Referring to Fig. 4, Fig. 5, suspension arm mechanism adopts two arm four-point lifting versions, single arm is by main arm 10, horizontal arm head 11, pull bar 12, two wirerope leading sheaves 13,14, base 15 is formed, main arm 10 and pull bar 12 two ends are hinged on respectively between horizontal arm head 11 and the base 15 and constitute parallelogram sturcutre, two wirerope leading sheaves 13,14 are installed on the horizontal arm head 11 before and after respectively, two main arms 10 of suspension arm mechanism, connect waling stripe 17 between 16 tops and the middle part respectively, 18, two main arms are connected into integral body, two bases 15,19 are fixedly mounted on the main frame cushion cap 3 respectively and lay respectively at two gigs 4,5 front sides.Luffing mechanism props up the luffing form before adopting single hydraulic cylinder, the piston of hydraulic luffing oil cylinder 20 and cylinder seat are hinged on respectively on waling stripe 18 and the main frame cushion cap 3, drive by fluid pressure drive device 21, its luffing action is to realize by the piston of hydraulic luffing oil cylinder 20 is flexible, the effect of luffing mechanism is by changing the elevation angle of arm, making the distance (being amplitude) of cage 7 hitch poinies and main frame cushion cap 3 center of gyrations obtain changing.
As shown in Figure 4, four suspention wireropes 6 are not held with a hanging box 9 and are captiveed joint, and the top of cage 7 adopts bearing pin with lock to removably connect with playing hanging box 9, fast, reliably.Since manned different with the cage specification of transporting the maintenance goods and materials, therefore need to change cage in the work, adopt this cage connection structure, can make things convenient for the replacing of cage, increase work efficiency.Four suspention wireropes 6 are divided into two groups, link to each other with two gigs 4,5 respectively by the guiding of the wirerope leading sheave on two horizontal arm heads 11, the 22 back other end respectively.
As shown in Figure 4, clump weight 8 is installed in the afterbody of main frame cushion cap 3, and clump weight 8 is the cast iron manufacturing, in the hope of producing most economical rational antidumping moment.
As Fig. 4, shown in Figure 1, cage 7 aluminium alloy materials are made, and have from heavy and light, intensity height, characteristics antirust and attractive in appearance.The electrical control dish (not shown) of the lifting of control cage, emergency braking is installed in the cage 7, realizes that the lifting of cage must be by the effect of operation of the control panel in the cage and realization extraordinary circumstances emergency braking.The top shrouding weighs down thing and injures personnel in the cage by a crashing object to prevent eminence.Crashproof guide wheel 701 is installed in all sides; cage 7 bottom mounting spring energy disperser 702 and lower position switch 703; four suspension centres in top all are equipped with the anti-upper limit position switch 704 of rushing to summit; cage 7 is established door 705 and the protection limit switch of closing the door is installed; the mercury switch at cage 7 inner installation and control cage angles of inclination is to guarantee the safe operation of cage 7.
As shown in Figure 4,3 are equipped with the cable take-up device 24 that drives by torque motor 23 on the main frame cushion cap, when cage 7 descends, the control cable of electrical control dish is pulled out from cable take-up device 24 under the effect of cage 7 deadweights in the cage, when cage 7 rises, cable fluffs, and cable take-up device 24 overcomes the cable deadweight cable is reclaimed under the driving of torque motor 23.
Manned lift truck of the present invention also is provided with one and is installed in truck chassis 1 time, with the vehicle traction system is the electrical generator of power, select SB-W4-30-WK.34 (P12) the type special power generator of Tai Hao company (three ripple Electric Machine Co., Ltd of former Tsing-Hua University) for use, when on-the-spot external source power supply trouble, guarantee the equipment normal operation as backup power.
In manned lift truck when work, drive to the appropriate location of permanent ship lock lock top lock head with manned lift truck, with four hydraulic rams of truck chassis vehicle frame outwards and stretch out downwards, makes the running wheel built on stilts, and adjust the level of vehicle frame.The degreeof turn of main control system cushion cap 3 is in respect to the required orientation of main frame cushion cap 3 center of gyrations cage 7, the elevation angle of the stroke control arm of modulated pressure amplitude oil cylinder 20 pistons, making the level interval of cage 7 hitch poinies and main frame cushion cap 3 center of gyrations is desirable value.Start gig and control system work, cage 7 is vertically transferred needs the driving surface that overhauls, safeguard and observe to the lock chamber.
Manned lift truck of the present invention also can be widely used in other places that is suitable for, for example bridge body of a bridge maintenance, when safeguarding, and the driving surface that cage need overhaul, safeguard to bridge is vertically transferred in the appropriate location to the bridge of manned lift truck can being travelled.
