Abstract
The utility model provides a movable support foot of a crane and belongs to the technical field of mechanical manufacture. The movable support foot of the crane is composed of a vertical oil cylinder and a spherical head, wherein a fixing sleeve is arranged outside the spherical head, the fixing sleeve is cylindrical, a base plate is arranged at the bottom of the fixing sleeve, a spherical clamping section, the spherical clamping section comprises a left section and a right section, after the left section and the right section are combined together, the inner wall is in a sphere shape to be matched with the spherical head, the outer wall is columnar and is matched with the inner wall of the fixing sleeve, the fixing sleeve and the spherical clamping section are provided with matched screw holes, and a screw is arranged in the screw holes. In the process of assembly, the spherical clamping section is covered on the spherical head, the fixing sleeve is sleeved outside the spherical clamping section, the screw penetrates the screw holes to enable the fixing sleeve and the spherical clamping section to be combined firmly into a whole, and the spherical head is capable of freely rotating in the spherical clamping section. The movable support foot is safe, reliable, flexible to use, strong in stability, and convenient to assemble.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of crane hoisting crane leg.
Background technology
During the lorry-mounted crane operation, supporting leg reaches horizontal maximum outreach, the support reaction of lifting weight acts on the supporting leg, require supporting leg that enough area of contact are arranged, and ground not exclusively is horizontal surface, requires to allow certain rotation in 360 ° of scopes of supporting leg, is in that supporting leg can not break away from Vertical Cylinders under the motoring condition, the sphere-contact that generally adopts is fixed with clamp, and supporting leg is very easily impaired, lose.
The utility model content
It is flexible that the technical problems to be solved in the utility model provides a kind of rotation, the hoisting crane movable supporting leg of stabilized structure.
The scheme of the utility model technical solution problem is to adopt Vertical Cylinders and bulb to consist of the hoisting crane movable supporting leg, there is fixed cover the bulb outside, and fixed cover is cylindric, and base plate is arranged at the bottom, the spherical clip lobe is installed between bulb and the fixed cover, the spherical clip lobe be about two lobes, be combined rear inwall and be spheric, coincide with bulb, outer wall is column, cooperate with the fixed cover inwall, the screw of cooperation is arranged on fixed cover and the spherical clip lobe, screw is arranged in the screw.During assembling, the spherical clip lobe is fastened on the bulb, fixed cover is sleeved on outside the spherical clip lobe, screw is passed screw makes fixed cover and the spherical clip lobe is firm is integrated, and bulb can freely rotate in the spherical clip lobe.
This practical new construction is safe and reliable, uses flexibly, and stability is strong, and is easy to assembly.
Description of drawings
Accompanying drawing 1 is cutaway view of the present utility model.
The specific embodiment
The utility model is made of Vertical Cylinders 1 and bulb 2, there is fixed cover 3 bulb 2 outsides, and fixed cover 3 is cylindric, and base plate 4 is arranged at the bottom, between bulb 2 and the fixed cover 3 spherical clip lobe 5 is installed, spherical clip lobe 5 be about two lobes, be combined rear inwall and be spheric, coincide with bulb 1, outer wall is column, cooperate with fixed cover 3 inwalls, the screw 6 of cooperation is arranged on fixed cover 3 and the spherical clip lobe 5, screw 7 is arranged in the screw 6.
