Embodiment Construction

[0032] The core of the present invention is to provide a dismounting device for outrigger pins of wheeled construction machinery. The dismounting device adopts hydraulic transmission technology and realizes plugging and pulling operations of pin shafts through oil cylinders, and has the characteristics of simple operation and high working efficiency. The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0033] Without loss of generality, this paper takes a wheeled crane as an example to describe in detail. It should be noted that the orientation words involved in this article, such as up, down, left, right, front, and rear, are defined based on the driver's perspective when driving. It should be understood that the use of the above-mentioned orientation words should not limit this article. The scope of protection sought by the application.

Abstract

The invention discloses a device for dismounting and mounting outrigger hinge pins of wheel type engineering machinery. The outrigger hinge pins are used for realizing the hinging between outriggers and a vehicle frame. The device comprises oil cylinders corresponding to the outrigger hinge pins and a hydraulic control loop, wherein a cylinder rod extending end of each oil cylinder is coaxially and fixedly connected with the corresponding outrigger hinge pin; and a control oil circuit of the hydraulic control loop is respectively communicated with cavities of the oil cylinders. Compared with the prior art, the device has the characteristics of simplicity for operation and labor saving and can be used for greatly increasing the working efficiency; and particularly for the operation of the hinge pin inserting, even through the centers of two structural members cannot be aligned correctly, the hinge pins can be inserted in reliably by means of hydraulic force. On the basis, the invention further provides the wheel type engineering machinery with the device for dismounting and mounting the outrigger hinge pins.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a disassembly and assembly device for a wheeled construction machinery and its outrigger pins. Background technique [0002] Wheeled cranes are widely used in various construction operations due to their convenient transfer characteristics. For wheeled cranes, the outriggers realize the basic function of supporting the frame by connecting with the frame. [0003] At present, the outrigger types of existing cranes are mainly divided into two types: one is H-type, when the crane is lifting, the outriggers at the front and rear ends of the frame protrude to both sides respectively, and it is H-shaped when viewed from above. One is X-type, when the crane is in operation, the outriggers on both sides of the frame are respectively placed to the two sides, and it is X-shaped when viewed from above. [0004] See figure 1 , which shows a top view of the existing X-shaped...
