[0024] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0025] refer to Figure 1 to Figure 3As shown, a PE gas pipeline air-stop clamp flattening recovery device includes an upper bushing 1, a lower bushing 2, an upper hinge seat 3, a lower hinge seat 4, a bushing hinge shaft 5, a mounting arm 6, a telescopic drive member 7, a front hinge shaft 8, a rear hinge shaft 9, a handle 10 and a reset spring 11.

[0026] The upper tile sleeve 1 and the lower tile sleeve 2 are both made of aluminum alloy or stainless steel, and have the advantages of being light and easy to operate, strong and corrosion-resistant, and can meet the construction environment of outdoor sites.

[0027] The upper sleeve 1 and the lower sleeve 2 are both semi-annular plate structures, so that a complete annular recovery structure is formed between the upper sleeve 1 and the lower sleeve 2. When in use, the upper sleeve 1 and the lower sleeve 2 are spliced ​​together to form a circular clamping space inside, which can clamp, restore and support the flattened PE pipe.

[0028] One side of the upper sleeve 1 is hinged to one side of the lower sleeve 2, and a mounting arm 6 is provided on the outer side of the lower sleeve 2, and a telescopic drive member 7 is hinged between the mounting arm 6 and the upper sleeve 1. The telescopic drive member 7 provides power, and the telescopic drive member 7 changes its length by telescoping, so as to realize the opening or closing of the hinge between the upper sleeve 1 and the lower sleeve 2.

[0029] An upper hinge seat 3 is fixed to the outer side of the upper sleeve 1, and a lower hinge seat 4 is fixed to the outer side of the lower sleeve 2. The lower end of the upper hinge seat 3 is hinged to the upper end of the lower hinge seat 4 through the sleeve hinge shaft 5, that is, the upper sleeve 1 and the lower sleeve 2 are both hinged through their corresponding hinge seats. The hinge seats ensure the realization of the hinge and also provide a basis for the installation of other components.

[0030] The upper hinge seat 3, the lower hinge seat 4 and the mounting arm 6 are all triangular structures, with a wide edge in the middle of the inner end, small angles at the upper and lower inner ends, and small angles at the outer ends. The upper hinge seat 3 is attached and welded to the outer arc surface of the upper sleeve 1, the lower hinge seat 4 is attached and welded to the outer arc surface of the lower sleeve 2, and the mounting arm 6 is attached and welded to the outer arc surface of the lower sleeve 2. This type of triangular structure can strengthen the outer side of the sleeve, ensure that the sleeve has a higher support strength, and avoid the problem of compression deformation, and the interior of the triangular structure is provided with a number of hollows.

[0031] The telescopic drive member 7 is a hydraulic cylinder, or other components that can provide telescopic driving force. The telescopic drive member 7 changes its length to realize the opening or closing of the hinge between the upper bushing 1 and the lower bushing 2. The front end of the telescopic drive member 7 is hinged to the outer end of the upper hinge seat 3 through the front hinge shaft 8, and the rear end of the telescopic drive member 7 is hinged to the outer end of the mounting arm 6 through the rear hinge shaft 9. The position adjustment during the hinge movement is realized through the hinge.

[0032] The upper sleeve 1 or the lower sleeve 2 is also provided with a handle 10, through which the entire device is controlled and held to ensure that the device can be restored in the clamped position. Preferably, the handle 10 is fixed to the outer end of the upper hinge seat 3, so that the lower sleeve 2 is relatively fixed during operation, and the upper sleeve 1 is rotated and opened and closed by the telescopic drive member 7.

[0033] A reset elastic member is provided between the outer end of the mounting arm 6 and the outer end of the upper sleeve 1. The reset elastic member is a reset spring 11. The reset spring 11 is utilized to provide a rebound force when the device is opened, so that the device can be conveniently taken out from the restored PE pipe. Similarly, when the device is put on the PE pipe for restoration, the telescopic drive member 7 must also overcome the elastic force of the reset spring 11 to realize the closure of the sleeve.

[0034] The working process of the utility model is as follows: an external force is applied by a hydraulic device to close the sleeve, thereby restoring the flattened part of the PE gas pipeline.

[0035] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.
