The specific embodiment

Below in conjunction with the drawings and specific embodiments technical solutions of the utility model being described in detail, with purpose, scheme and the effect of further understanding the utility model, but is not as the restriction to the utility model claims protection domain.

The utility model is a kind of walking, drive dual-purpose suspension mounts car, can transport suspension and mount the position to appointment, then by pallet rise, descend, vertically move, actions such as side travel, revolution, beat accurately locate and finish and mount.

Fig. 1 mounts the structural plan of car for the utility model suspension; As shown in Figure 1, this suspension mounts car and comprises that running gear, drive system, steering swivel system, lifting mount system, reach management system, described running gear is a guide front wheel 2 and two tricycle structures that split driving trailing wheel 9 compositions of installation, middle for mounting operating mechanism---the lifting hanging device comprises lifting arm 20 and pallet 15.Driver seat is equipped with storage battery 14 and manual pump 12 for 13 times, and driver seat 13 back are provided with diesel fuel tanks 11; Driving engine 3 vertically is positioned over car right front portion (watching in the same way with the driver's seat), drives Variable plunger pump 4 by elastic coupling, gear type pump 5 of Variable plunger pump 4 rear portions series connection; Parts such as oil radiator 19 and hydraulic valve are pressed in the tapping of car right middle, and right back of car is placed hydraulic reservoir 6.Guide front wheel 2 is made up of the parallel installation of two-wheeled.

Fig. 2 and Fig. 3 be respectively the utility model suspension mount car walking operation mount under the situation and the driver behavior situation under structural representation; As shown in Figures 2 and 3, management system comprises riding manipulation control system and walking management system, described riding manipulation control system and described walking management system carry out the switching of driving model or walking pattern by a cover shifter, this shifter comprises that one manually switches the operating mode conversion knob on wheel 22 and the driver behavior panel, wherein manual switchover wheel 22 changes the mode of direction of traffic, and operating mode conversion knob switches the motion control system of two kinds of operation modes.Under the walking operation mode, pulling realization by a vertical shaft and control pull rod 1 by manpower turns to, pneumatic strut bar 17 two ends are hinged on respectively on control pull rod 1 and the wheel flutter 18, played the effect of support fixation control pull rod 1, switch on the maneuver box 16 can carry out sequence of operations such as lifting, translation, revolution, beat to lifting arm 20 and pallet 15, finishes specifically mounting operation.Under driving model, need forward control pull rod 1 to the reversing sense and the locking of walking operation, operating personal can be controlled direction of traffic by the direction of passage dish, uses the switch on the control panel to adjust the lifting of car body and the spacing of drive wheel.

Fig. 4 is the steering swivel system scheme drawing that this suspension mounts car; As shown in Figure 4, wheel flutter 18, tension wheel 23, ratio wheel 24, arc tooth synchronous belt 25 and bearing circle 26, front-wheel 2 etc. are formed steering hardware, can realize driving and two kinds of pattern control of walking direction of traffic by rotation manual switchover wheel 22, bearing circle 26 driven gears motion under the driving model, wheel flutter 18 is in sliding state, and is inoperative.Under the walking operation mode, bearing circle then no longer works, and drives wheel flutter 18 by control stalk 1 and realizes turning to of vehicle.

Fig. 5 is the hydraulic gear scheme drawing that this suspension mounts car; Comprise that travel driving system and lifting mount drive system.With reference to figure 5, plunger pump 4, hydraulic reservoir 6, motor 8, filter, cooling vessel and the duct coupling etc. that are installed on the trailing wheel constitute a Closed Hydraulic travel driving system.Driving engine 3 drives plunger pump 4 by a coupler and drives described motor 8, and then driving trailing wheel 9 travels.Under the driving model, control the starting that mounts car, walk and stop, running brake and Parking Brake are housed on the CD-ROM drive motor 8 by Das Gaspedal and brake pedal; Under the walking operation mode, the swash plate by the acceleration cable on the control pull rod 1 and forward-reverse switch control plunger pump 4 just can make and mount car and start to walk, walk and stop, and need not to operate clutch and braking.The driving that lifting mounts system is the lifting arm jacking system that is driven the lifting hanging device by driving engine 3 driven gear pumps 5, the pallet work system, and car body and wheel is apart from changing-breadth system, and then the driving lifting system of mounting carries out accurately, mounts flexibly operation.

With reference to figure 1～6, of the present utility modelly mount car to mount the working process of operation as follows: after guaranteeing that suspension safety is placed into pallet 15, operating personal is driven and is mounted car near mounting a little, in order to ensure the stability that mounts, lifting car body as required, and by controlling car body and wheel mounts car apart from changing-breadth system (comprising left amplitude oil cylinder 10 and right amplitude oil cylinder 7) adjusting rear track, after the position is determined well, rotation manual switchover wheel 22, make control pull rod 1 can change direction of traffic, the acceleration cable device is equipped with on control pull rod 1 top, can hand the control arm that pull bar 1 spurs acceleration cable simultaneously, hand has determined the moving velocity of vehicle to the strength size of acceleration cable control arm, for security consideration, control ability to acceleration cable limits to some extent, and maximum speed per hour is no more than the average velociity of people's walking.Operating mode conversion knob on the rotation driver behavior panel is to handle operation gear, promptly finish the conversion of walking operation mode, the stand that this moment, operating personal used control pull rod 1 and acceleration cable control rod pair to mount car is finely tuned, use operating case 16 to regulate the motion of lifting arm 20 and pallet 15 then, mount operation: the elevating ram 21 in the lift arm jacking system stretches out, and pallet 15 steadily rises with the rising of lifting arm 20.Mount thing near after mounting a little, elevating ram 21 stops action, change (comprising vertical shift oil cylinder 151, sideslip oil cylinder 152 rolling pendulum oil cylinders 153 and swing type mechanism 154) position and the angle of pallet 15 according to the pallet work system on the fine position pallet 15 that mounts a little, if needed can manual regulation swing type mechanism 154, make pallet 15 rotations.Implement after the position adjustment accurately to mount, with suspension be placed to mount a little on.Elevating ram 21 is regained, and lifting arm 20 is got back to original position, and rotation manual switchover wheel is got back to original position, and the blocked operation mode is changed knob to driving model, and trailing wheel 9 wheelspans return to virgin state, finish mounting operation, can scorch leave the work-yard.

Principle of work is as follows: it is Variable plunger pump 4 bonded assembly gear type pumps 5 that driving engine 3 drives the hydraulic pressure main pump, and it is flexible that hydraulic oil promotes elevating ram 21 through hydraulic valve, pallet 15 finished mounted action (and negative actuation).Its work schematic block diagram as shown in Figure 6.

Though the utility model discloses as above with a preferred embodiment; right its is not in order to limit the utility model; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
