Abstract
The utility model discloses a horizontal supporting leg for a portable push-pull crane. An oil pipe is arranged in the horizontal supporting leg, and the friction resistance is small. The horizontal supporting leg comprises a supporting leg box; two supporting legs, namely a left supporting leg and a right supporting leg, are arranged in the supporting leg box; a rolling bearing and a sliding block are arranged in the supporting leg box; a vertical oil cylinder is fixedly arranged at the outer ends of the supporting legs; an oil pipe of the vertical oil cylinder is arranged in the supporting leg box; a push-pull hand shank is fixedly arranged on the outer sides of the supporting legs; and the left supporting leg and the right supporting leg are stacked in the supporting leg box in the longitudinal direction. The horizontal supporting leg has the advantages that the supporting legs are stretched by pushing and pulling the push-pull hand shank on the outer sides of the supporting legs by a hand; all points in the supporting leg box, which are contacted with the supporting legs, are in rolling friction with a rolling bearing, so that effects of quickness and convenience are achieved; the hydraulic oil pipe is arranged in the supporting leg box; and the horizontal supporting leg is sunscreen and anti-aging and is not suitable to be hung and touched, so that the reliability is improved, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of small-sized flow-type hydraulic lift accessory device, relates in particular to a kind of light plug-type crane horizontal supporting leg.
Background technology
Existing minor crane horizontal support legs, its structure are that supporting leg is installed in the supporting leg case, and drawing handle is installed on the supporting leg, and when using supporting leg, directly mostly push-and-pull supporting leg in the supporting leg case is cliding friction between supporting leg and the supporting leg case, and friction drag is big, wastes time and energy.And the oil pipe of existing hoisting crane is that design is exterior at car body, and oil pipe is exposed to the weather and is prone to wear out, and it is bad to expose the clashing and breaking of easy extension.
Summary of the invention
The purpose of the utility model provides the built-in oil pipe of a kind of ability, and the little light plug-type crane horizontal supporting leg of friction drag.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of light plug-type crane horizontal supporting leg, comprising: the supporting leg case, in the supporting leg case supporting leg is installed, supporting leg is divided into left and right two supporting legs, and its characteristics are: in the described supporting leg case antifriction-bearing box is installed, antifriction-bearing box is between supporting leg case and supporting leg; Slide block also is installed between supporting leg case and the supporting leg, and slide block is fixedly mounted in the supporting leg case, and the outer end of supporting leg is installed with vertical oil cylinder, and the oil pipe of vertical oil cylinder is built in the supporting leg case.
According to above-mentioned plug-type crane horizontal supporting leg, its characteristics are: the outside of described supporting leg is installed with drawing handle.
According to above-mentioned plug-type crane horizontal supporting leg, its characteristics are: described left and right supporting leg forward and backward stacking in the supporting leg case.
The utility model has the advantages that: use this practical when new-type; Pull the drawing handle of leg outer side, can realize the flexible of supporting leg, because of all being the antifriction-bearing box friction of rolling with the contact point of supporting leg in the supporting leg case; Realized quick and portably; Hydraulic oil pipe is built in the supporting leg case, has realized sun-proof anti-aging, should not hang and bump, and has increased reliability, has prolonged service life.

Fig. 3 is left and right supporting leg forward and backward structural representation birds-eye view that stacks in the supporting leg case in the utility model.
In the accompanying drawing
1, supporting leg case 2, supporting leg 3, oil pipe 4, vertical oil cylinder 5, drawing handle 6, antifriction-bearing box 7, slide block
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of light plug-type crane horizontal supporting leg, like Fig. 1, shown in 2, comprising: supporting leg case 1; Supporting leg 2 is installed in the supporting leg case 1; Supporting leg 2 is divided into left and right two supporting legs, and antifriction-bearing box 6 is installed in the supporting leg case 1, and antifriction-bearing box 6 is between supporting leg case 1 and supporting leg 2; Between supporting leg case 1 and the supporting leg 2 slide block 7 is installed also, slide block 7 is fixedly mounted in the supporting leg case 1, and the outer end of supporting leg 2 is installed with vertical oil cylinder 4, and the oil pipe 3 of vertical oil cylinder 4 is built in the supporting leg case 1.
In the present embodiment, the outside of supporting leg 2 is installed with drawing handle 5.
In the present embodiment, left and right supporting leg is forward and backward stacking in supporting leg case 1, and is as shown in Figure 3.
The beneficial effect of the utility model is: oil pipe is built in the supporting leg case, and minimizing is tanned by the sun, and increases the service life; The rolling of antifriction-bearing box drives supporting leg push-and-pull campaign, and friction drag is little, and is time saving and energy saving.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and protection domain to the utility model limits; Under the prerequisite that does not break away from the utility model design concept; Common engineering staff make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model.
