Abstract
The utility model relates to a hydraulic turnover support leg of a lorry-mounted crane. The hydraulic turnover support leg comprises a panel and a support board, wherein the panel is provided with a positioning board 1 and an adjusting bolt; the support board is provided with a positioning board 2, a fixed sleeve and a positioning sleeve; and the panel and the support board are rotatably connected with each other by a rotating shaft and are fixedly positioned and connected with each other by a positioning pin. When arranging a prearranged lorry-mounted crane, the hydraulic turnover support leg is arranged on a telescopic leg. When the hydraulic turnover support leg is not in use, a telescopic horizontal leg firstly and outwards extends, a movable leg extends out of a rotatable leg gas cylinder to swing a positioning pin to be connected with a fixed seat board, and then the telescopic horizontal leg is withdrawn, so that the occupied space is reduced. When the hydraulic turnover support leg is in use, the telescopic horizontal leg outwards extends, the positioning pin is withdrawn, the rotatable leg gas cylinder is withdrawn, the turnover support leg is downward swayed, and the panel and the support board are flattened and are fixed with each other by the positioning pin, so that the hydraulic turnover support leg can be telescopic to support the gas cylinder. Therefore, the hydraulic turnover support leg has the advantages of flexible use, simple structure, convenient operation and high work efficiency, and can be used for arranging a prearranged lifting appliance on the big-tonnage lorry-mounted crane.
Description
[technical field]
The utility model belongs to the weight-lifting equipment technical field, relates to the hydraulic overturn supporting leg of installing on the telescopic movable leg when a kind of lorry-mounted crane is adorned preposition hanging.
[background technology]
Existing lorry-mounted crane is when adorning preposition loop wheel machine, because lorry-mounted crane occupies and the restriction in space, chassis, often be difficult to assembling, for addressing the above problem, under most situation, need to install manually upset supporting leg, because manually the upset supporting leg is relatively heavier, underaction, relatively more difficult during use, by manually wanting 2-3 people could realize the upset of supporting leg at least, and when the bottom, have certain potential safety hazard.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of hydraulic overturn support leg device of installing on the base movable leg, the hydraulic overturn supporting leg is soldered to movable leg by panel, by back plate, rotating shaft, be soldered to realize the overturning rotation of supporting leg of panel, chain and small oil tank on the movable leg, link to each other with supporting oil cylinder by back plate, fix the lorry-mounted crane hydraulic overturn supporting leg that to play a supporting role in use by locating plate and locating dowel pin.
The technical method that its technical matters that solves the utility model adopts is: a kind of lorry-mounted crane hydraulic overturn supporting leg, comprise panel and back plate, locating plate one is housed on panel and regulates bolt, locating plate two, fixed cover and locating bush are housed on back plate, rotary connection by rotating shaft between panel and the back plate, and connect by the locating dowel pin stationary positioned.
Described locating dowel pin is provided with the locating bush that prevents that locating dowel pin from coming off.Seat board on the described panel links to each other with an end of chain, and the other end of chain links to each other with commentaries on classics leg oil cylinder.Described chain mainly contains leaf chain and fork plate.Be connected by bolt between described back plate and the supporting oil cylinder.Described locating dowel pin also is provided with the knock hole that matches and use.
The beneficial effects of the utility model are: when the preposition lorry-mounted crane of assembling, the utility model is installed on the Retractive leg, stretch out flexible horizontal leg when not using earlier, commentaries on classics leg oil cylinder is stretched out on the movable leg to be put, with locating dowel pin it is connected with fixed base plate, regain flexible horizontal leg again, so just reduce institute and take up space; Flexible horizontal leg is stretched out, take out locating dowel pin, change the leg oil cylinder and regain the upset supporting leg bottom, make panel and back plate leveling then and fix, so just can stretch supporting oil cylinder with locating dowel pin; The utlity model has the advantage of using flexible, simple in structure, easy to operate and high efficiency, adorn under the preposition situation of hanging at the large-tonnage lorry-mounted crane and use, can not influence traffic safety.
[description of drawings]
Structural representation when Fig. 1 is the utility model work;
Structural representation when Fig. 2 is the utility model gathering.
Among the figure: 1-panel, 2-locating dowel pin, 3-back plate, 4-supporting oil cylinder, 5-locating plate one, 6-regulate bolt, 7-chain, 8-rotating shaft, 9-commentaries on classics leg oil cylinder, 10-locating plate two, 11-fixed link, the flexible horizontal leg of 12-.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1 and Fig. 2, a kind of lorry-mounted crane hydraulic overturn supporting leg comprises panel 1 and back plate 3, locating plate 1 is housed on panel 1 and regulates bolt 6; Locating plate 2 10, fixed cover and locating bush are housed on back plate 3; Realize rotation by rotating shaft 8 between panel 1 and the back plate 3, come location and installation by locating dowel pin 2.Prevent that by the locating bush on the locating dowel pin 2 locating dowel pin 2 from coming off; Supporting oil cylinder 4 stretches out the loop wheel machine work that realizes; Chain 7 mainly contains leaf chain and fork plate, one end of chain 7 links to each other with seat board on the panel 1, the other end of chain 7 links to each other with commentaries on classics leg oil cylinder 9, by changeing realize the overturning rotation of supporting leg of stretching of leg oil cylinder 9, when stretching out, leg oil cylinder 9 drives the center of circle rotation of chain 7 when changeing around the chain adapter plate, supporting oil cylinder 4 and back plate 3 rotate around rotating shaft 8, when forwarding swing up position to, adjusting bolt 6 blocks chain 7 and prevents that corner is excessive, knock hole on locating plate 1 and the locating plate 2 10 is concentric at this moment, passes knock hole with locating dowel pin 2 and fixes the upset supporting leg; When changeing leg oil cylinder 9 and shrink, the upset supporting leg to lower swing, forwards knock hole on panel 1 and the back plate 3 to when concentric under the drive of changeing leg oil cylinder 9 and chain 7, fixing with locating dowel pin 2.Dress is during locating dowel pin 2, prevents coming off of locating dowel pin 3 with locating bush on fixed link 11 and the locating dowel pin 2 and the locating bush on the back plate 3.The utlity model has characteristics simple in structure, safe and convenient to use, adorn under the preposition situation of hanging at the large-tonnage lorry-mounted crane and use.
