Problems solved by technology

In the actual production process, due to the existence of manufacturing errors, the docking of steel pipes and steel pipes, steel pipes and equipment boxes often has misalignment.
[0003] In the event of misalignment of the butt joint of the pipeline, due to the hard material of the steel pipe itself, it cannot be adjusted by itself, so we can only find another way when assembling the current vehicle
For example, when the electrical threading pipe under the vehicle is misplaced, it is usually necessary to cut off part of the steel pipe and improve it with a soft connection (that is, change the steel pipe at the butt joint to a nylon hose), while when the brake pipe is misplaced, it is only necessary to change the structure , not only reduces the production efficiency, but also increases the manufacturing cost

Embodiment 1

[0022] Such as Figure 1 to Figure 3 As shown, a floating butt joint provided by the present invention is used to connect piece one 1 and piece two 2. hole structure.

[0023] The joints include split joint one 3 and joint two 4 . Joint one 3 is composed of a head 3a and a tail 3b, and joint two 4 is also composed of a head 4a and a tail 4b. The tail portion 3b of joint one 3 is fixedly connected with piece one 1, the tail portion 4b of joint two 4 is fixedly connected with piece two 2, the head 3a of joint one 3 is connected with the head 4a of joint two 4, and then piece one 1 is connected with Pieces two 2 are connected together. Wherein, the head 3a of the first joint 3 and the head 4a of the second joint 4 are configured to be relatively radially floating, so that when there are manufacturing and installation errors between the first 1 and the second 2 to be connected , when the central axes of piece 1 and piece 2 are not on a straight line, the relative position in t...

Embodiment 2

[0033] The difference from Embodiment 1 is that, as Figure 4 As shown, the first part 1 and the second part 2 in this embodiment are both electric wire pipes, and a nut 7 and a nut 7' are respectively sleeved on the front ends of the first part 1 and the second part 2, and are described in the first embodiment. The joint realizes the butt connection between the pipe and the pipe.

[0034] The working process is as follows: Figure 4 As shown, when the center line of part 2 (wire conduit) deviates from the center line of part 1 (wire pipe) due to manufacturing and installation errors, first screw the tail 4b of joint 2 4 and nut 7' into the part The end of the second 2 is tightened and fixed by the external thread on the tail 4b and the nut 7', adjust the relative position of the head 4a of the joint 2 4 and the head 3a of the joint 1 3, and insert the pipe end of the joint 1 1 into the joint In the tail part 3b of one 3, finally tighten the nut 7 installed on part one 1, an...

Embodiment 3

[0036] The difference from the first embodiment is that the head 3a of the first joint 3 has an integrated structure, and an internal spline groove (not shown in the figure) is provided on one side of its opening. Correspondingly, at the head of the second joint 4 4a is provided with an external spline protrusion. When installing, it is only necessary to insert the external spline protrusion of the joint 2 head 4a into the internal spline groove of the joint 1 head 3a, and then adjust the relative position of joint 1 3 and joint 2 4 , and then rotate and clamp, the connection between joint one 3 and joint two 4 can be realized, and this structure can be used to connect joint one 3 and joint two 4 when the vehicle is assembled.

[0037] The floating butt joint provided by the present invention, through the arrangement of joint one 3 and joint two 4 that can float relative to each other in the radial direction, successfully solves the problems between pipes and pipes and between ...

Abstract

The invention relates to a floating butt joint. The floating butt joint comprises a first joint and a second joint which are separated from each other; each of the first joint and the second joint iscomposed of a head portion and a tail portion; the tail portions of the first joint and the second joint are fixedly connected with a first member and a second member respectively; the head portions of the first joint and the second joint are connected; the first joint and the second joint are configured to float relatively and radially. The floating butt joint successfully solves the problem of manufacturing and installation errors between two connecting parts in the current vehicle construction within a certain range, realizes smooth butt-jointing, and has a simple structure, is convenient to install and disassemble, is high in reliability, and can improve production efficiency greatly, and can reduce the manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of pipeline joints, in particular to a floating butt joint which is movable and can adjust butt joint holes. Background technique [0002] With the rapid development of rail transit, the train manufacturing industry is increasing day by day. In the production process, the electrical and brake plates are usually inseparable from the connection between steel pipes and steel pipes, and between steel pipes and equipment boxes. However, in the actual production process, due to the existence of manufacturing errors, misalignment often occurs in the butt joints of steel pipes and steel pipes, and steel pipes and equipment boxes. [0003] In the event of misalignment of the butt joints of the pipelines, due to the hard material of the steel pipe itself, it cannot be adjusted by itself, so we can only find another way when assembling the existing vehicle. For example, when the electrical threading pipe under the veh...
