Abstract
Description
Technical Field
[0001] The utility model relates to a well pipe construction frame, belonging to the technical field of building construction. Background Art
[0002] Currently, well pipe installation in construction requires first laying a casing, then hoisting the pipe into the casing for installation and welding. In actual construction, the verticality of the welded well pipe is unsatisfactory, and there is a risk of the lifting lock disengaging and sliding into the wellbore during installation. Therefore, there is an urgent need for an auxiliary construction tool that can solve these problems. Summary of the Invention
[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a well pipe construction frame, which plays an auxiliary positioning role for the well pipe, ensures the verticality of the well pipe during construction, and prevents the well pipe from slipping into the wellbore during construction.
[0004] The purpose of this utility model is achieved in this way:
[0005] A well pipe construction frame includes a frame body, on which two groups of cover plate assemblies are slidably arranged, each group of cover plate assemblies includes a baffle slidably arranged on the frame body, the cover plate is hinged to the baffle, and the mating ends of the two cover plates are respectively provided with semicircular construction holes, and a stop pin is movably inserted on the frame body to block the baffle.
[0006] Preferably, the distance between the stop pins at the left and right ends is equal to the sum of the lengths of the two cover plates.
[0007] Preferably, the frame includes two frames and a plurality of running crosspieces connected between the frames, and the stop pins are movably plugged into the frames.
[0008] Preferably, the baffle is a T-shaped structure, with two shoulders of the T-shaped baffle resting on two frame frames, and a middle portion of the T-shaped baffle inserted between the two frame frames.
[0009] Preferably, the width of the cover plate is greater than the distance between the two frames.
[0010] Preferably, the stop pins at both ends are connected to the two sets of cover plate assemblies respectively through chains.
[0011] Preferably, the stop pins at both ends are connected to the two baffles or cover plates respectively through chains.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] The utility model can conveniently position the well pipe before operation, thereby ensuring the verticality of the well pipe during installation and welding operations, and can effectively prevent the well pipe from sliding down into the well hole through the limited cooperation operation of the construction hole on the cover plate and the stop nail on the outer wall of the well pipe, thereby improving the construction efficiency and construction effect and ensuring the safety of construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Stop pin 4. DETAILED DESCRIPTION
[0020] See also Figure 1 and Figure 2 The utility model relates to a well pipe construction frame, which includes a frame body composed of a frame 1 and a walking crossbar 2. The frame 1 is provided with two parallel frames, and multiple walking crossbars 2 are connected between the two frames, and the walking crossbars 2 are located at both ends of the frame body.
[0021] Each frame 2 is provided with two pin holes for inserting stop pins 4 to limit the position of the baffle 3.1. The T-shaped baffle 3.1 is inserted downwardly between the two frames 1, that is, the two shoulders of the T-shaped baffle 3.1 rest on the two frames 1, and the middle of the T-shaped baffle 3.1 is inserted between the two frames 1. The cover plate 3.2 is hinged to the baffle 3.1, and the width of the cover plate 3.2 is greater than the distance between the two frames 1, so that the cover plate 3.2 can be placed on the frame. The mating ends of the two cover plates 3.2 are respectively provided with semicircular construction holes 3.3. When the two cover plates 3.2 are flipped downward and mated, the two semicircular construction holes 3.3 form a through hole that can just accommodate the well pipe.
[0022] When in use, first set up the frame of the well pipe construction frame of the present invention on the casing, then flip and open the two cover plates 3.2 to the left and right ends respectively, and then hang the well pipe down into the casing. When the well pipe is lowered to the frame and is about to approach the stop nails on the well pipe, flip the cover plate 3.2 and cover it on the frame, and then the well pipe continues to descend until the stop nails are placed on the pipe plate 3.2, thereby limiting the position of the well pipe, so that the well pipe remains stable during the welding process, and the verticality is limited by the construction hole 3.3.
[0023] When the construction is completed, the stop pin 4 is pulled out, and the baffle 3.1 can be easily driven to move the cover plate 3.2 along the frame 1 to the left and right ends, and subsequent operations can be conveniently performed.
[0024] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
