Problems solved by technology

The domestic market mainly relies on imports, but imports are expensive and have a long cycle, which affects the construction period and the interests of partners
[0003] In the existing technology, such as figure 1 and figure 2 As shown, it includes a pull rod 3, the sleeve 2 is covered on the pull rod 3, and the end of the sleeve 2 is locked with the wall 1 through a plurality of screws 4. The connection method is simple and the cost is low, but its installation is troublesome. Screw positioning is used, the positioning is inaccurate, it takes a long time, prolongs the process of changing the channel of the expanded diameter product, and the work efficiency is low

Embodiment Construction

[0020] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0021] Such as image 3 , Figure 4 and Figure 5 As shown, the fixing device for steel pipe pipe expanding diameter pull rod sleeve of the present embodiment includes a pull rod 3 on which a diameter expanding head 5 is installed, and one end of the pull rod 3 is sleeved with a flange sleeve 6, and the flange sleeve 6 The outer side is provided with a boss 7, which also includes a wall 1, and one side of the wall 1 is provided with a groove to cooperate with the boss 7, and the top and bottom of the flange sleeve 6 connected to the wall 1 are respectively equipped with connecting plates 11. The connecting plate 11 is fixed by set screws 10.

[0022] The connecting plate 11 has a "┎┐" structure.

[0023] The cross section of the flange sleeve 6 is a square structure.

[0024] The flange sleeve 6 is placed on the outer peripheral surfa...

Abstract

The invention relates to a pipeline expansion pull rod sleeve fixing device for a steel pipe. The pipeline expansion pull rod sleeve fixing device comprises a pull rod, wherein an expanding head is arranged on the pull rod, a flange sleeve is sleeved on one end of the pull rod, and a lug boss is arranged on the outer side of the flange sleeve; the pipeline expansion pull rod sleeve fixing device also comprises a wall body, wherein a groove cooperatively connected with the lug boss is arranged on one side of the wall body, the top and the bottom of the flange sleeve which is connected with the wall body are respectively provided with a connecting plate, and the connecting plates are fixed through set screws. The pipeline expansion pull rod sleeve fixing device is reasonable in structure and convenient to assemble and disassemble; the efficiency of a tool between the flange sleeve of the pull rod and the wall body is greatly improved, and the time of a track change procedure of an expanded product is shortened.

Description

technical field [0001] The invention relates to the technical field of diameter-expanding equipment, in particular to a steel pipe pipe diameter-expanding tie rod sleeve fixing device. Background technique [0002] At present, there are very few manufacturers producing diameter-expanding tie rods in the market, and there are even fewer manufacturers producing diameter-expanding tie rods with qualified properties such as high hardness, tensile strength and toughness. The domestic market mainly relies on imports, but imports are expensive and have a long cycle, which affects the construction period and the interests of partners. [0003] In the prior art, such as figure 1 and figure 2 As shown, it includes a pull rod 3, the sleeve 2 is covered on the pull rod 3, and the end of the sleeve 2 is locked with the wall 1 through a plurality of screws 4. The connection method is simple and the cost is low, but its installation is troublesome. Screw positioning is used, the positi...
