[0003] To this end, the utility model provides a suspension arm outrigger span fine-tuning mechanism to solve the above technical problems. Utility Model Content

[0004] Purpose of the utility model: To solve the problem in the prior art that it is difficult to fine-tune the span after the outriggers and the boom are installed during crane installation. Usually, the span is fixed and the deviation cannot be adjusted during installation, which easily causes deviation in the installation position of the outriggers and affects the lifting effect of the crane.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A suspension arm outrigger span fine-tuning mechanism, comprising:

[0007] A clamping plate, the clamping plate is used to clamp the supporting legs, and two of the clamping plates are fixedly and symmetrically arranged on the boom;

[0008] A bottom plate, which is arranged at the bottom of the two clamping plates and fixed by welding;

[0009] A leg shaft, which passes through the two clamping plates and fixes the leg between the two clamping plates;

[0010] A gasket is provided between the clamping plate and the supporting leg, and the gasket is inserted into the gap between the clamping plate and the supporting leg to fine-tune the left and right positions of the supporting leg.

[0011] Furthermore, the support leg shaft includes an upper support leg shaft and a lower support leg shaft, the lower support leg shaft is fixed by bolts, and a clamping plate is provided between the bolts and the clamping plate to prevent wear between the bolts and the clamping plate; the outer sleeve of the upper support leg shaft is provided with a sleeve, the upper support leg shaft is fixed by bolts, and a clamping plate is provided between the bolts and the sleeve to prevent wear, and a spacer sleeve is provided on the side of the sleeve that contacts the clamping plate.

[0012] Furthermore, the gasket is inserted into the gap between the upper leg shaft and the lower leg shaft, and the gasket is removed when adjusting the position of the leg, and is inserted into the gap after adjustment to prevent the leg from being displaced.

[0013] Furthermore, the number of the gaskets is at least six, and the number of the gaskets inserted on the left and right sides is adjusted according to the position of the legs.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By setting the splints, leg shafts and gaskets, the legs can be fixed between the splints. After adjusting the position of the legs, the gaskets are inserted into the gaps between the splints and the legs to fix the positions of the legs. When it is necessary to fine-tune the left and right positions of the legs, it is only necessary to pull out the gaskets on the left and right sides of the legs and then insert them after adjustment. This structure facilitates fine-tuning of the leg positions when installing the legs, thus avoiding the problem of being unable to install due to deviations in the leg positions.

[0020] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0021] The applicant believes that in the prior art, it is difficult to fine-tune the span after the outriggers and the boom are installed. Usually, the span is fixed and the deviation cannot be adjusted during installation, which can easily cause deviations in the outrigger installation position and affect the lifting effect of the crane.

[0022] To this end, the applicant designed Figure 1-3The illustrated mechanism for fine-tuning the span of a boom 3 and a leg 2 comprises: a clamp 1, which is used to clamp the leg 2, and two clamps 1 are fixedly and symmetrically arranged on the boom 3; a base plate 4, which is arranged at the bottom of the two clamps 1 and fixed by welding; a leg 2 axis, which passes through the two clamps 1 and fixes the leg 2 between the two clamps 1; a gasket 5, a gap is left between the clamp 1 and the leg 2, and the gasket 5 is inserted into the gap between the clamp 1 and the leg 2 for fine-tuning the left and right positions of the leg 2.

[0023] Further optionally, in this embodiment, the shaft of the support leg 2 includes an upper shaft of the support leg 2 and a lower shaft of the support leg 2, the shaft of the lower leg 2 is fixed by bolts 7, a clamping plate 8 is provided between the bolts 7 and the clamping plate 1 to prevent wear between the bolts 7 and the clamping plate 1; the outer sleeve of the shaft of the upper leg 2 is provided with a shaft sleeve 9, the shaft of the upper leg 2 is fixed by bolts 7, a clamping plate 8 is provided between the bolts 7 and the shaft sleeve 9 to prevent wear, and a spacer sleeve 10 is provided on the side of the shaft sleeve 9 that contacts the clamping plate 1.
