Description

Technical Field

[0001] The utility model relates to the technical field of gas maintenance auxiliary equipment, in particular to a standpipe live-joint maintenance auxiliary device. Background Art

[0002] Currently, a specific operation in the gas industry involves replacing the gaskets and rubber rings of riser joints. Currently, the tools used in this process are relatively bulky.

[0003] Regarding situations where gaskets need to be replaced due to air leakage at the coil riser joint, the current practice is usually to directly shut down the corresponding ball valve at the front end, and then empty the remaining air in the pipeline behind the rear end valve before performing the operation. The main disadvantages of this practice are as follows: the operation process lacks effective and specialized auxiliary tools or devices to effectively prevent the stress from causing misalignment between the upper and lower risers after the riser joint is disassembled. The stress caused by this misalignment is generally large, and it is difficult for operators in the suspended state to easily correct and align the upper and lower risers with their bare hands. Therefore, this process often requires operators to spend a lot of time to temporarily find ways to force the alignment, which not only wastes time and affects efficiency, but also increases the operator's excessive force in the suspended state, which is detrimental to safety. Utility Model Content

[0004] In order to solve the above problems, the utility model aims to propose a vertical pipe joint maintenance auxiliary device, which can realize the early restraint of the upper and lower gas risers at the joint position, effectively correct the misalignment of the upper and lower risers, and facilitate the operator to smoothly complete the joint fault handling operation.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A standpipe joint maintenance auxiliary device includes a frame body, and the upper and lower sides of the frame body are provided with movable jaws for clamping the gas standpipes at the upper and lower ends of the joint. The movable jaws are provided with an opening, and adjustment bolts are provided on both sides of the opening.

[0007] Furthermore, the size of the opening is slightly larger than the outer diameter of the gas riser.

[0008] Furthermore, the frame body includes an upper fixed plate and a lower fixed plate, and the upper fixed plate and the lower fixed plate are connected by a connecting rod.

[0009] Furthermore, the upper fixed plate and the lower fixed plate are both triangular fixed plates, and the upper fixed plate and the lower fixed plate are connected via three corresponding connecting rods.

[0010] Beneficial effects: The utility model clamps and fixes the gas risers at the upper and lower ends of the joint in advance through the movable jaws, and limits and fixes them through the adjusting bolts; it prevents the gas risers from being misplaced, and facilitates the operator to smoothly complete the joint fault handling operation.

[0015] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0017] Example 1

[0018] See also Figure 1-3 : A standpipe joint maintenance auxiliary device includes a frame body 1, and the upper and lower sides of the frame body 1 are provided with movable jaws 4 for clamping the gas riser 3 at the upper and lower ends of the joint 2. The movable jaws 4 are provided with an opening, and adjusting bolts 401 are provided on both sides of the opening.

[0019] In this embodiment, the gas risers at the upper and lower ends of the joint are clamped and fixed in advance by movable jaws, and are fixed in position by adjusting bolts; thus, the gas risers are prevented from being misaligned, making it easier for operators to successfully complete the joint fault handling operation.

[0020] In a specific example, the size of the opening is slightly larger than the outer diameter of the gas riser 3 .

[0021] In a specific example, the frame body 1 includes an upper fixed plate 101 and a lower fixed plate 102 , and the upper fixed plate 101 and the lower fixed plate 102 are connected via a connecting rod 103 .

[0022] In a specific example, the upper fixing plate 101 and the lower fixing plate 102 are both triangular fixing plates, and the upper fixing plate 101 and the lower fixing plate 102 are connected via three corresponding connecting rods 103 .

[0023] The frame body of this embodiment is a triangular frame structure, which improves the stability of the device structure.

[0024] The working principle of the device of this embodiment is as follows:

[0025] The operator brings the device down to the vicinity of the target joint on the outer wall of the building; tightens the device on the upper and lower galvanized gas risers at the joint position, and tightens the corresponding adjusting bolts; the operator removes the joint as planned, and determines the maintenance and treatment measures (either replacing the joint, or replacing the gasket, or replacing and updating both); after replacing the gasket or the joint, the upper and lower risers need to be fastened together with the joint, which is the process in which the auxiliary device plays its core role; the device of this embodiment can restrain the upper and lower risers of the joint, and can effectively correct the misalignment of the upper and lower risers, so that the operator can smoothly complete the joint fault treatment operation.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
