Embodiment Construction

[0011] Such as figure 2 It is a schematic diagram of the structure of the present invention, a new type of installation structure of the central rotary joint, including a mounting platform 1, a sleeve 2, a nut rod 3, and a central rotary joint 4. There is a The four bushings 2 are elevated, and the nut rod 3 passes through the bushing 4 to fix the central swivel joint 4 on the installation platform 1 . The oil ports of the central rotary joint 4 are located on the bottom surface of the central rotary joint 4 .

[0012] The central rotary joint is raised with four bushings 2, and then the central rotary joint 4 is fixed on the installation platform 1, that is, the construction machinery chassis, by means of a nut rod 3 passing through the bushings 2. This installation method can ensure that the maintenance personnel can replace the central rotary joint and perform maintenance work on the rubber hose joint part on the platform, without the need to enter under the frame. In ad...

Abstract

The invention relates to the technical field of rotary drilling rigs and particularly relates to a novel installing structure of a central swivel joint. The novel installing structure comprises an installing table, bushings, a nut rod and the central swivel joint, wherein the four bushings are arranged between the central swivel joint and the installing table and are used for elevating the central swivel joint, the nut rod penetrates through the bushings to fix the central swivel joint to the installing table, and oil ports of the central swivel joint are all formed in the bottom surface of the central swivel joint. With the adoption of the installing structure, maintainers can change the central swivel joint and maintain a joint part of a rubber pipe on a platform without needing to enter the space beneath a frame.

Description

technical field [0001] The invention relates to the technical field of rotary drilling rigs, in particular to a novel installation structure of a central rotary joint. Background technique [0002] Generally, the boarding platform and the chassis of construction machinery are relatively rotating. The function of the central swivel joint is to keep the oil circuit between the platform and the chassis connected during the rotation of the machine, so as to ensure that the platform can rotate freely 360°. Such as figure 1 As shown, the central swivel joint is directly installed on the mounting surface of the frame, and the hose joint is under the mounting surface. The picture shows the chassis of the YCR60 small rotary drilling rig. It can be seen that the distance between the bottom of the frame and the ground is only 310mm, and it is difficult for adults to enter under the frame to install and maintain the rubber hose joint under the central rotary joint. Since the rubber ho...
