Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline detection, in particular to a gas pipeline detection device. Background Art

[0002] Gas pipeline is a term in civil engineering, mainly used to transport combustible gases, especially natural gas. Natural gas pipeline is the main way to transport large quantities of natural gas on land. It transports natural gas from the mining site or processing plant to the urban gas distribution center or industrial enterprise users, and is also called a gas transmission pipeline.

[0003] Chinese patent number CN202323526670.0 discloses a gas pipeline detection device, comprising a detector body, an upper arc clamp, and a lower arc clamp. The upper and lower arc clamps are hinged at one end and each has a connecting block at the other end. The connecting blocks are bolted together. The detector body is mounted on the upper arc clamp, and the detection end of the detector body extends to the lower end of the upper arc clamp. The inner walls of the upper and lower arc clamps are each provided with at least one support, each of which is rotatably provided with a roller. Compared with the prior art, this utility model has the advantages of improving the detection accuracy of gas pipelines, thereby reducing potential safety hazards.

[0004] Although the above patent can be moved on the gas pipeline for inspection, when the gas pipeline needs to be installed between the upper arc clamp and the lower arc clamp for inspection, it is necessary to continuously turn the bolt to remove it from the connecting block, and then flip the upper arc clamp upward to place the gas pipeline between the upper arc clamp and the lower arc clamp. At this time, in order to facilitate the installation of the gas pipeline, the separation state of the upper arc clamp and the lower arc clamp cannot be fixed, and the hand needs to continuously hold the position of the upper arc clamp, which is more cumbersome for the installation of the gas pipeline. Utility Model Content

[0005] The purpose of the utility model is to provide a gas pipeline detection device to address the defects and shortcomings of the existing technology.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a gas pipeline detection device, comprising an upper arc clamp and a lower arc clamp, one end of the upper arc clamp and the lower arc clamp are hingedly connected by a hinge, four supports are provided on the inner walls of the upper arc clamp and the lower arc clamp, each of the supports is rotatably provided with a roller, and the other ends of the upper arc clamp and the lower arc clamp are respectively provided with an upper connecting block and a lower connecting block, a fixing device is provided between the upper connecting block and the lower connecting block for fixing the upper connecting block and the lower connecting block when the upper connecting block and the lower connecting block are abutted, the side end face of the upper connecting block is provided with an extension plate, the side end face of the lower connecting block is rotatably provided with a rotating column, and an elliptical disk is provided on the rotating column.

[0007] A further improvement is that the fixing device is a buckle respectively arranged between the upper connecting block and the lower connecting block, there are two buckles in total, and the two buckles are symmetrically arranged at the front and rear ends of the upper connecting block and the lower connecting block.

[0008] A further improvement is that a driving device for driving the upper connecting block to abut against the lower connecting block is further provided between the upper connecting block and the lower connecting block.

[0009] Further improvements are: the driving device includes an arc rod arranged on the upper end surface of the lower connecting block, an arc through-hole opened on the upper connecting block and loosely matched with the arc rod, a limit plate arranged on the upper end of the arc rod, and an arc spring sleeved on the arc rod, the upper end of the arc spring abuts against the lower end of the limit plate, the lower end of the arc spring abuts against the upper end surface of the upper connecting block, the center position of the arc rod is the same as the center position of the upper arc clamp and the lower arc clamp, and the center position of the arc through-hole is the same as the center position of the arc rod.

[0010] A further improvement is that a clamping member is provided between the elliptical disk and the extension plate, for clamping with the extension plate when the elliptical disk lifts the extension plate to increase the rotation resistance of the rotating column.

[0011] A further improvement is that the engaging member includes an arc protrusion provided on the elliptical disk and an arc groove provided on the lower end surface of the extension plate for engaging with the arc protrusion, and the arc protrusion is provided on the long axis end of the elliptical disk.

[0012] After adopting the above technical solution, the beneficial effect of the utility model is as follows: when it is necessary to install the gas pipeline between the upper arc clamp and the lower arc clamp for inspection, the fixation between the upper connecting block and the lower connecting block is first released by the fixing device, and then the elliptical disk is rotated to drive the rotating column to rotate on the lower connecting block. When the elliptical disk rotates ninety degrees, the long axis of the elliptical disk lifts the extension plate, thereby driving the upper arc clamp to flip upward through the upper connecting block. At this time, the elliptical disk remains stationary, thereby continuously separating the upper arc clamp and the lower arc clamp. There is no need to hold the position of the upper arc clamp with your hands continuously. The gas pipeline can then be installed on the roller between the upper arc clamp and the lower arc clamp, which is relatively simple to install the gas pipeline.

[0013] Further effect: in the process of the long axis of the elliptical disk lifting the extension plate to flip upward, the arc spring gradually contracts to generate elastic potential energy. After the elliptical disk stops rotating, the arc spring releases the elastic potential energy, causing the upper connecting plate to apply pressure toward the lower connecting plate, so that the lower end of the extension plate abuts against the long axis of the elliptical disk, which can further increase the rotational resistance of the elliptical disk to drive the rotating rod; when the elliptical disk is rotated another ninety degrees, the arc spring continues to release elastic potential energy, thereby driving the upper connecting plate to abut against the lower connecting plate, and there is no need to manually press the upper connecting plate and the lower connecting plate together again.

[0014] Further effect: the fastening and releasing speeds between the upper connecting plate and the lower connecting plate can be increased by performing the mating fixation through the buckle.

[0015] Further effect: when the elliptical disk rotates 90 degrees to lift the extension plate, the arc protrusion is stuck on the arc groove, thereby increasing the resistance of the elliptical disk to left and right rotation, and improving the separation stability between the upper arc clamp and the lower arc clamp.

DETAILED DESCRIPTION

[0022] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0023] See Figures 1 to 4As shown, the technical solution adopted in this specific embodiment is: a gas pipeline detection device, comprising an upper arc clamp 1 and a lower arc clamp 2, one end of the upper arc clamp 1 and the lower arc clamp 2 are hingedly connected by a hinge, four supports 3 are provided on the inner walls of the upper arc clamp 1 and the lower arc clamp 2, each of the supports 3 is rotatably provided with a roller 4, and the other ends of the upper arc clamp 1 and the lower arc clamp 2 are respectively provided with an upper connecting block 5 and a lower connecting block 6, a fixing device is provided between the upper connecting block 5 and the lower connecting block 6 for fixing the upper connecting block 5 and the lower connecting block 6 when they are in contact, the side end face of the upper connecting block 5 is provided with an extension plate 7, the side end face of the lower connecting block 6 is rotatably provided with a rotating column 8, and the rotating column 8 is provided with an elliptical disk 9.

[0024] The fixing device comprises a buckle 10 disposed between the upper connecting block 5 and the lower connecting block 6. There are two buckles 10, symmetrically disposed at the front and rear ends of the upper connecting block 5 and the lower connecting block 6. The locking tongue of the buckle 10 is disposed on the side end surface of the lower connecting block 6, and the locking body of the buckle 10 is disposed on the side end surface of the upper connecting block 5. The buckle is conventional and will not be described in detail here.

[0025] A driving device for driving the upper connecting block 5 to abut against the lower connecting block 6 is further provided between the upper connecting block 5 and the lower connecting block 6 .

[0026] The driving device includes an arc rod 11 arranged on the upper end surface of the lower connecting block 6, an arc through hole 12 opened on the upper connecting block 5 and loosely matched with the arc rod 11, a limit plate 13 arranged on the upper end of the arc rod 11, and an arc spring 14 sleeved on the arc rod 11, the upper end of the arc spring 14 abuts against the lower end of the limit plate 13, and the lower end of the arc spring 14 abuts against the upper end surface of the upper connecting block 5, the center position of the arc rod 11 is the same as the center position of the upper arc clamp 1 and the lower arc clamp 2, and the center position of the arc through hole 12 is the same as the center position of the arc rod 11.

[0027] A locking member is provided between the elliptical disk 9 and the extension plate 7 for locking with the extension plate 7 when the elliptical disk 9 lifts the extension plate 7 to increase the rotation resistance of the rotating column 8 .

[0028] The engaging member includes an arc protrusion 15 provided on the elliptical disk 9 and an arc groove 16 opened on the lower end surface of the extension plate 7 for engaging with the arc protrusion 15. The arc protrusion 15 is provided on the long axis end of the elliptical disk 9.

[0029] The working principle of the utility model is as follows: when the gas pipeline needs to be installed between the upper arc clamp 1 and the lower arc clamp 2 for inspection, the fixation between the upper connecting block 5 and the lower connecting block 6 is first released by the buckle 10, and then the elliptical disk 9 is rotated to drive the rotating column 8 to rotate on the lower connecting block 6. When the elliptical disk 9 is rotated ninety degrees, the long axis of the elliptical disk 9 pushes up the extension plate 7, thereby driving the upper arc clamp 1 to flip upward through the upper connecting block 5. During this process, the arc spring 14 gradually contracts to generate elastic potential energy. After the elliptical disk 9 stops rotating, the arc spring 14 releases the elastic potential energy, causing the upper connecting plate to apply pressure in the direction of the lower connecting plate, thereby allowing the lower end of the extension plate 7 to abut against the long axis of the elliptical disk 9. The rotational resistance of the rotating rod driven by the elliptical disk 9 can be further improved, and when the elliptical disk 9 rotates ninety degrees to lift the extension plate 7, the arc protrusion 15 is stuck on the arc groove 16, thereby increasing the resistance of the elliptical disk 9 to the left and right rotation, and the stability of the separation between the upper arc clamp 1 and the lower arc clamp 2 can be improved. At this time, the elliptical disk 9 remains stationary to continuously separate the upper arc clamp 1 and the lower arc clamp 2. There is no need to hold the position of the upper arc clamp 1 by hand. Then the gas pipeline can be installed on the roller 4 between the upper arc clamp 1 and the lower arc clamp 2, and the lock body and lock tongue of the buckle 10 are matched to fix the upper connecting plate and the lower connecting plate, which is relatively simple to install the gas pipeline.
