Referring to fig. 1 to 5 together, a description will now be given of a natural gas pipeline installation clamping device provided by the present utility model. The natural gas pipeline installation clamping device comprises a seat plate 1 and two translation clamping components 2, wherein the two translation clamping components 2 are respectively and slidably connected to the seat plate 1 and used for driving two adjacent sections of natural gas pipelines 10 to approach each other or to depart from each other, the translation clamping components 2 comprise a translation seat 21, two clamping plates 22 which are slidably connected to the translation seat 21, and a first bidirectional screw 23 which is rotationally connected to the translation seat 21 and used for driving the two clamping plates 22 to approach each other or depart from each other, a translation groove 211 which extends along a direction perpendicular to the sliding direction of the translation seat 21 is formed in the top surface of the translation seat 21, the first bidirectional screw 23 penetrates through the two clamping plates 22 and extends along the trend of the translation groove 211, and clamping grooves 221 which are oppositely arranged for clamping or loosening the natural gas pipelines 10 are respectively formed in adjacent sides of the two clamping plates 22;
wherein, the lower extreme of grip block 22 is equipped with upset slider 222, upset slider 222 threaded connection is on first two-way screw rod 23, link up respectively on the both sides wall of translation seat 21 and be equipped with the upset groove 212 that is used for supplying the vertical upset of upset slider 222, and two upset grooves 212 are close to the both ends setting of translation seat 21 respectively.
Compared with the prior art, the natural gas pipeline installation clamping device provided by the embodiment has the advantages that the two clamping plates 22 slide relatively in the translation seat 21 to be close to each other so as to fixedly clamp the ports of two adjacent sections of natural gas pipelines 10, and then the two translation clamping parts 2 slide relatively along the seat plate 1 so that the ports of the two natural gas pipelines 10 to be connected can be in concentric butt joint so as to be fixedly connected into a whole; after the pipe connection is completed, the two clamping plates 22 of the translation clamping component 2 slide away from and away from the translation seat 21 respectively along the translation seat so as to loosen the natural gas pipe 10, and when the clamping plates 22 slide to the end part of the translation seat 21, the clamping plates can longitudinally overturn to a toppling state along the overturning groove 212, so that the overall height of the natural gas pipe installation clamping device is reduced, the natural gas pipe installation clamping device can be conveniently moved out from the bottom of the connected natural gas pipe 10, the practicability of the device is improved, and great convenience is provided for installation work.
In this embodiment, the two translational clamping members 2 are slidably connected to the same seat plate 1, so as to ensure concentric docking of the natural gas pipeline 10. Each translational clamping member 2 comprises a translational seat 21 slidably connected to the seat plate 1 and two clamping plates 22 slidably connected to the translational seat 21, the translational seat 21 is provided with a first bidirectional screw 23 penetrating through the translational seat 21 to enable the two clamping plates 22 to approach or depart from each other in the translational seat 21, and the sliding direction of the clamping plates 22 is perpendicular to the sliding direction of the translational seat 21. Each clamping plate 22 is provided with an arc-shaped clamping groove 221, and the clamping grooves 221 of the two clamping plates 22 on the same translational clamping component 2 can be attached to the peripheral wall of the natural gas pipeline 10 so as to effectively clamp the natural gas pipeline 10.
It should be noted that, while the clamping plate 22 slides along the translation groove 211 under the drive of the first bidirectional screw 23 and also has a tendency to rotate, the clamping plate 22 can only slide horizontally along the translation groove 211 due to the abutting action of the groove walls on both sides of the translation groove 211 against the turning slider 222. In view of this, the overturning groove 212 is formed on the side wall of the translation seat 21, when the connection of the natural gas pipeline 10 is completed and the two clamping plates 22 slide away from each other, the overturning slider 222 slides to the overturning groove 212, and the overturning slider 222 overturns around the first bidirectional screw 23 to one side of the overturning groove 212 due to the loss of the abutting of the groove walls, so as to drive the clamping plates 22 to overturn to a toppling state. Since the screw directions of both sides of the first bi-directional screw 23 are opposite, the two clamping plates 22 screw-coupled to the first bi-directional screw 23 have opposite turning directions, so that the turning grooves 212 at both ends are respectively provided at both opposite sides of the translation seat 21. When the next clamping operation is performed, the first bidirectional screw 23 is reversed, and the two clamping plates 22 are turned to an upright state under the driving of the first bidirectional screw 23, so as to continuously slide along the translation groove 211 towards each other to clamp the natural gas pipeline 10.
Further, the bottom of the turning slider 222 is arc-shaped, so that the turning slider will not be jammed in the translation groove 211 when turning around the first bidirectional screw 23; meanwhile, the width of the turnover slot 212 is slightly larger than the width of the turnover slider 222, and the height of the turnover slider 222 is higher than the turnover slot 212, so as to realize smooth turnover of the clamping plate 22.
The first bidirectional screw 23 may be driven by a motor reducer or manually rotated, and when the motor is used, the motor should meet the requirement of forward and reverse rotation, in this embodiment, the first bidirectional screw 23 is specifically rotated and connected to the wall of the translation groove 211, the other end of the first bidirectional screw penetrates through the wall of the translation groove 211 to extend outwards and is provided with a rotating handle, and the rotating handle may be provided with anti-skidding threads or an anti-skidding rubber sleeve.
When the natural gas pipeline 10 needs to be butt-jointed and installed, the natural gas pipeline installation clamping device is placed on the bottom wall of the groove at the butt-joint position, the clamping grooves 221 of the two translation clamping components 2 are respectively sleeved on the periphery of the port of the natural gas pipeline 10, the first bidirectional screw 23 is rotated, the two clamping plates 22 of the translation clamping components 2 slide towards each other to enable the two clamping grooves 221 to be tightly attached to the periphery wall of the natural gas pipeline 10, and the port of the two natural gas pipelines 10 is in a concentric clamping state because the structural dimensions of the two translation clamping components 2 are identical, and then the two translation clamping components 2 slide towards each other along the seat plate 1 to drive the port of the two natural gas pipelines 10 to be close, so that the butt-joint work is conveniently completed. When the butt joint is completed, the first bidirectional screw 23 is reversely rotated to drive the two clamping plates 22 to slide and separate back, so that the clamping plates 22 are loosened and are far away from the natural gas pipeline 10 and then turned over, and the blockage of the natural gas pipeline 10 to the turning process of the clamping plates 22 can be avoided. If the distance between the two translation clamping components 2 is too short when the butt joint is completed, and the clamping plate 22 is blocked from overturning, after the clamping plate 22 is loosened for a certain distance, the two translation clamping components 2 can slide back along the seat plate 1, so that enough space is provided for overturning the clamping plate 22. When the clamping plates 22 slide to align the turning blocks with the turning grooves 212, the two clamping plates 22 are turned to a toppled state toward the turning grooves 212 on both sides, respectively, so that the height of the natural gas pipeline installation clamping device is sufficiently reduced, and the natural gas pipeline installation clamping device is easily removed from between the natural gas pipeline 10 and the bottom wall of the groove.
As a specific embodiment of the natural gas pipeline installation clamping device provided by the utility model, referring to fig. 5, a positioning hole 223 is provided on the turning slider 222, and a positioning piece 24 that is in plug-in fit with the positioning hole 223 to lock the clamping plate 22 and the translation seat 21 is provided on the side wall of the translation seat 21.
In this embodiment, when the two clamping plates 22 slide towards each other to abut against the outer peripheral wall of the natural gas pipeline 10, the positioning member 24 is inserted into the positioning hole 223, so as to prevent the two clamping plates 22 from sliding relative to each other, and ensure that the clamping plates 22 are in an effective clamping state. The positioning member 24 is only required to be disposed corresponding to one overturning slider 222. After the butt joint is completed, the positioning piece 24 needs to be pulled out, and the first bidirectional screw 23 is reversely rotated to enable the clamping plate 22 to loosen the natural gas pipeline 10.

For the natural gas pipe 10 with a smaller diameter, the first bidirectional screw 23 is turned first to bring the two clamping plates 22 close to each other to abut against each other, and at this time, the circumference formed by the clamping groove 221 is larger than the outer diameter of the natural gas pipe 10, so that the natural gas pipe 10 needs to be further clamped by the auxiliary clamping assembly 3. Specifically, the pushing pieces push the sliding pushing plates 32 on two sides respectively, so that the sliding pushing plates 32 on two sides slide towards the middle simultaneously, the pushing pieces 33 are driven to gather towards the center direction, and the arc-shaped bending plates 331 on the pushing pieces 33 can be attached to the peripheral wall of the natural gas pipeline 10 to effectively clamp the natural gas pipeline 10.
