Abstract
Disclosed is a multi-legs flexible mechanism of radiation-style of single-cylinder-driven. The utility model is characterized in that four hold-down supports 2 are provided on the periphery of a hold-down support 11, four legs1are provided on the hold-down supports in the manner of flexibility, and the legs which are centered on the hold-down support are arranged with radial radiation. A driven cylinder 10 is vertically fixedly connected in the middle of the hold-down support, and a terminal area 9 is fixedly connected with a cylinder rod of the cylinder 10-1. A gear 4 of the legs flexible mechanism 12 is engaged with the upper and the lower racks, a push bar 6, rocking bar 7 and a small push bar 8 are connected among the gear, the hold-down support and the terminal area. The device has the advantages that the bearing of the chassis of vehicle is reasonable, the stability is good, the weight is light and the structure is simple.
Description
The utility model relates to the leg mechanism on the vehicle such as a kind of construction machinery and equipment.
The used leg mechanism of vehicles such as present construction machinery and equipment generally needs four oil cylinders.Though and W-outrigger is taken into account with four oil cylinders and is used for flexible and supports, its supporting leg extension elongation is shorter, so only be suitable for dilly.Above-mentioned supporting leg telescoping mechanism all is located at the front and rear part on chassis, and stressed unreasonable, the weight on chassis are strengthened.Be positioned at the both sides on chassis after supporting leg stretches out in addition, can only improve the lateral stability of vehicle like this, the fore-and-aft stability of vehicle is not had help.In order to improve the fore-and-aft stability of vehicle, then to increase counterweight, increased the weight of complete machine so again.Also there are shortcomings such as complex structure, cost height in said mechanism.
The purpose of this utility model is a kind of single many supporting legs of hydraulic oil cylinder driving radiant type telescoping mechanism of design, it should make the stressed reasonable of vehicle chassis, and improved the stability of the front and back and the both sides of vehicle, it also makes vehicle need not increase counterweight, has advantage in light weight, simple in structure, that cost is low.
The utility model includes supporting leg 1, supporting leg beam 2, driving oil cylinder 10, fixed bearing 11, terminal pad 9, supporting leg telescoping mechanism 12, four supporting leg beams 2 be installed in fixed bearing 11 around, four supporting legs 1 are respectively being installed on four supporting leg beams 2 along supporting leg beam 2 flexible modes, four supporting legs 1 are that the center is radial radiation shape layout with fixed bearing 11, driving oil cylinder 10 vertical fixing are connected the middle part of fixed bearing 11, terminal pad 9 is captiveed joint with the piston rod 10-1 of driving oil cylinder 10, and terminal pad 9 and fixed bearing 11 are respectively and be connected with a supporting leg telescoping mechanism 12 between each supporting leg 1.During operation, vertical driving oil cylinder 10 is flexible, and it drives terminal pad 9 up-and-down movements, and supporting leg telescoping mechanism 12 promotes supporting leg along the protruding or inside withdrawal of supporting leg beam simultaneously.
It is flexible that the utility model only needs an oil cylinder can drive supporting leg.Arrange because supporting leg is the radial radiation shape, so its strained condition and reasonableness are better than the supporting leg of other form.Supporting leg can reach the outside of equipment when operation, can improve the stability of complete machine effectively, saves the counterweight of vehicle.It has advantage in light weight, simple in structure, that cost is low.
Fig. 1 is the structural representation after the utility model supporting leg 1 stretches out, the structural representation when Fig. 2 is 1 withdrawal of the utility model supporting leg, and Fig. 3 is the birds-eye view of Fig. 1.
Embodiment one: present embodiment is made up of supporting leg 1, supporting leg beam 2, driving oil cylinder 10, fixed bearing 11, terminal pad 9, supporting leg telescoping mechanism 12.Four supporting leg beams 2 be installed in fixed bearing 11 around.Four supporting legs 1 are installed in respectively on the supporting leg beam 2, and supporting leg 1 can be inwardly outer flexible along supporting leg beam 2, and supporting leg 1 is that the center is radial radiation shape layout with fixed bearing 11.Driving oil cylinder 10 vertical fixing are connected the middle part of fixed bearing 11, and terminal pad 9 is captiveed joint with the piston rod 10-1 of driving oil cylinder 10.Terminal pad 9 and fixed bearing 11 are respectively and be connected with a supporting leg telescoping mechanism 12 between each supporting leg 1.
Embodiment two: present embodiment and embodiment one are different is supporting leg telescoping mechanism 12 by upper rack 3, gear 4, tooth bar 5 down, push rod 6, broadcast bar 7, little push rod 8 is formed.Upper rack 3 is fixedly connected on the below that supporting leg beam 2 is put the beams in place, and following tooth bar 5 is fixedly connected on the supporting leg 1, and gear 4 and meshes with upper rack 3 and following tooth bar 5 respectively between upper rack 3 and following tooth bar 5.One end and the gear 4 of push rod 6 are hinged, and an end of the other end of push rod 6 and rocking bar 7 is hinged, and the other end of rocking bar 7 and fixed bearing 11 are hinged, and an end of little push rod 8 is hinged on the middle part of rocking bar 7, and the other end of little push rod 8 and terminal pad 9 are hinged.During operation, vertical oil cylinder 10 shrinks, and drives terminal pad 9 upward movements, with the hinged little push rod 8 of terminal pad 9 then jack-up rocking bar 7 make it to promote push rod 6 and outwards make extensional motion.To outer rolling, gear 4 drives supporting legs 1 by following tooth bar 5 and outwards does to stretch out to move along supporting leg beam 2 with the speed greater than one times at gear 4 centers push rod 6 driven wheels 4, and supporting leg 1 is all stretched out along upper rack 8.Because the increment effect of gear 4 makes supporting leg 1 stretch out long distance, can improve the stability of complete machine so effectively.Other composition is identical with embodiment one with annexation.
