The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1 to 6, the pipeline pressure test fixture of this embodiment includes roof 1, pipe clamp 2 that is located the roof below, the spliced pole 3 of connecting roof and pipe clamp, be located roof and pipe clamp between briquetting 4, rotationally locate the actuating lever 5 on the briquetting with roof threaded connection and bottom, the surface of briquetting is equipped with the air inlet, the bottom surface of briquetting be equipped with the seal groove 6 of air inlet intercommunication.

The utility model discloses a pipeline pressure testing anchor clamps through with the spliced pole spiro union on the roof to rotationally set up the mode on the briquetting with its bottom, realized the removal drive to the briquetting. The setting of pipe clamp has realized the orificial fixed of butt joint pipe, and operating personnel accessible rotates the mode of actuating lever like this, and the briquetting of its bottom of drive descends to will take over the orificial pressure of pipe in the seal groove, thereby realize the orificial sealed of butt joint pipe, so that follow-up relevant equipment carries out the gas tightness test to it. Compared with the original pipe orifice clamp for the connecting pipe, the pipe pressure test clamp is simpler to operate, and meanwhile, the pipe clamps can be replaced by operators to realize the adaptation of the connecting pipes of different models, so that the universality is improved.

The top plate and the connecting column form a frame body of the pipeline pressure test fixture, and two ends of the connecting column can be respectively connected with the top plate and the pipe clamp in a threaded, welded or interference fit mode.

In this embodiment, the top of spliced pole is connected with the roof through the screw thread, and threaded connection layer board 7 is passed through to the bottom of spliced pole, and the pipe clamp is located the top of layer board. The pipe clamp and the supporting plate are both arc-shaped plates, and the end part of the pipe clamp is also provided with a bayonet 8 matched with the bottom end of the connecting column.

During installation, an operator clamps the bottom of the connecting column in the bayonet, and then presses the pipe clamp on the supporting plate through the nut 9 above the pipe clamp.

When the pipe orifices of different types of connecting pipes are sealed, an operator can realize the adaptation with the pipe orifices of the connecting pipes of the types by replacing the pipe clamps of the corresponding types. Specifically, the operator first loosens the nut above the pipe clamp and then can take the pipe clamp off the supporting plate. And then the operator can install the pipe clamps of the corresponding models in a similar manner.

The pressure block is used for sealing the pipe orifice of the connecting pipe and ventilating the pipe orifice of the connecting pipe so as to realize pressure test of the butt joint pipe.

The driving rod is used for driving the pressing block to move towards the nozzle of the connecting pipe so as to press the pressing block on the nozzle of the connecting pipe. The middle part of the pressure block is connected with the top plate through threads, and the bottom end of the pressure block is rotatably arranged on the pressure block.

In this embodiment, an air inlet pipe 10 communicated with the air inlet is arranged on the side surface of the pressing block. A transverse air channel 11 extending from the air inlet to the middle part of the pressing block is transversely arranged in the pressing block, and a longitudinal air channel 12 extending from the transverse air channel to the sealing groove is also arranged in the pressing block.

The surface of briquetting can set up mounting groove 13, sets up bearing 14 in the mounting groove, and the fixed part and the briquetting of bearing are connected, and the rotation portion and the actuating lever of bearing are connected.

The bearing realizes the purpose of rotationally arranging the driving rod on the pressing block, and simultaneously reduces the friction between the driving rod and the pressing block. In addition, operating personnel also can set up the bearing and realize rotatable being connected between actuating lever and the briquetting in the bottom of actuating lever, and its specific structure is similar with above-mentioned, and this is no longer repeated here.

Preferably, a pressing plate 15 fixedly connected with the pressing block can be further arranged above the bearing, and the bottom end of the driving rod penetrates through a through hole in the surface of the pressing plate and is connected with the bearing.

The two sides of the pressure plate can be provided with a positioning hole 16 or a positioning groove, and the connecting column passes through the positioning hole or the positioning groove.

The setting of clamp plate has realized installing the purpose in the mounting groove with the bearing on the one hand, and simultaneously, the locating hole or the constant head tank of its both sides can prevent that the briquetting from following the actuating lever and rotating.

In specific implementation, the bottom end of the driving shaft is provided with a ring groove 17, and the pressing plate is formed by splicing two semicircular plates 19 with U-shaped forks 18 on one side. The semicircular plate is fixedly connected with the pressing plate through a bolt, and the two fork arms of the U-shaped fork surround to form the positioning holes or the positioning grooves. The middle part of clamp plate has the perforation, and during the installation, this annular is aimed at to two semicircle boards to block the actuating lever, prevent that its bottom from droing in the mounting groove.

A handle 20 may also be provided at the top end of the drive rod to facilitate rotation of the drive rod by an operator.

When the pipe clamp works, an operator firstly places the pipe orifice of the connecting pipe on the pipe clamp so that the boss on the outer side of the pipe orifice of the connecting pipe is in contact with the pipe clamp. Then, an operator can rotate the driving rod through the handle, and due to the fact that the driving rod is in threaded connection with the top plate, the bottom end of the driving rod gradually drives the pressing block to descend along with continuous rotation of the driving rod until the pipe orifice of the connecting pipe completely enters the sealing groove and is pressed tightly by the pressing block.

After the pipe orifice of the connecting pipe is tightly pressed on the pipe clamp by the pressing block, an operator can gradually input an external air source into the connecting pipe through the air inlet and the sealing groove by corresponding equipment, and the operator can perform air tightness test on the connecting pipe after the gas input is finished, so that the operation is very simple and convenient.
