Examples

As shown in fig. 1, 3 and 4, the pipe fixing device provided in the present embodiment includes a pipe clamp 10 having a chucking groove; the clamping groove 20 is provided with a first pressing surface 131 and a second pressing surface 111, the first pressing surface 131 and the second pressing surface 111 are arranged oppositely and at intervals, and the first pressing surface 131 can move close to and away from the second pressing surface 111 along a first direction and a second direction so as to enable the clamping groove 20 to clamp or release the pipe body in the clamping groove 20; the first direction is a vertical direction, and the second direction is perpendicular to the first direction.

In the example of the placement position in fig. 4, the first direction is the up-down direction, and the second direction is the left-right direction.

In this embodiment, the pipe body is a steel pipe in the hydraulic pipeline, that is, the pipe fixing device is used for fixing the steel pipe in the hydraulic pipeline. The steel pipe can be embedded in the clamping groove 20 and clamped by the clamping groove 20, so that the steel pipe is fixed.

Specifically, the clamping groove 20 has a first pressing surface 131 and a second pressing surface 111, the first pressing surface 131 and the second pressing surface 111 are arranged opposite to each other and at an interval, and the steel pipe is pressed between the first pressing surface 131 and the second pressing surface 111. During the in-service use, first pressing surface 131 can be close to and keep away from along vertical direction relative second pressing surface 111, and first pressing surface 131 can also be close to and keep away from along horizontal direction relative second pressing surface 111 simultaneously, and then realizes the chucking and the release to being located the inside steel pipe of chucking groove 20. Meanwhile, it is because the first pressing surface 131 moves in the first direction and moves in the second direction relative to the second pressing surface 111, so that not only the adjustment of the size of the clamping space for clamping the steel pipe in the clamping groove 20, but also the adjustment of the clamping point of the steel pipe relative to the clamping groove 20 is realized. The adjustment of the size of the clamping space is related to the diameter of the steel pipe clamped in the clamping groove 20, the larger the clamping space is, the larger the pipe diameter of the steel pipe is, and the smaller the clamping space is, the smaller the pipe diameter of the steel pipe is. The adjustment of the clamping point refers to the adjustment of the position of the steel pipe relative to the first pressing surface 131 and the second pressing surface 111, and the adjustment of the clamping point is closely related to the adjustment of the clamping space. For example, when the number of the clamping grooves 20 is two, a steel pipe is clamped in each clamping groove 20, and when the diameters of the two steel pipes are increased, the position of the first pressing surface 131 relative to the second pressing surface 111 needs to be adjusted, so that the clamping space is increased, and simultaneously, the two steel pipes are respectively far away from the clamping points of the respective clamping grooves 20, so that the distance between the pipe shafts of the two steel pipes is increased. On the contrary, if the diameters of the two steel pipes are reduced and the clamping space is reduced, the two steel pipes can approach each other, that is, the two steel pipes approach the clamping points of the respective clamping grooves 20, so that the distance between the pipe shafts of the two steel pipes is reduced.

With continued reference to fig. 1, 3 and 4, the pipe clamp 10 preferably includes a bottom plate 11, side plates 13 and a connecting block 12; the bottom plate 11 and the side plate 13 are arranged opposite to each other at intervals, the connecting block 12 is connected between the bottom plate 11 and the side plate 13, the bottom plate 11, the connecting block 12 and the side plate 13 together form a clamping groove 20, the first pressing surface 131 is arranged on one side surface of the side plate 13 facing the bottom plate 11, and the second pressing surface 111 is arranged on one side surface of the bottom plate 11 facing the side plate 13; the side plate 13 is movable in a first direction and a second direction relative to the connecting block 12. In the present embodiment, the number of the clamping grooves 20 is two, and the two clamping grooves 20 are respectively located at both sides of the connecting block 12 in the second direction.

Specifically, connecting block 12 and bottom plate 11 form the T style of calligraphy structure of invering jointly, and connecting block 12 can divide into two parts about bottom plate 11 promptly, and then forms two chucking grooves 20 that are used for chucking steel pipe, and each chucking groove 20 all corresponds a curb plate 13, and the upper surface of bottom plate 11 is first pressure face 131 this moment, and the lower surface of curb plate 13 is second pressure face 111. The position of the inner side plate 13 relative to the connecting block 12 in the same clamping groove 20 is adjusted, so that the clamping space in the clamping groove 20 is adjusted. Taking the clamping groove 20 on the left side of the connecting block 12 as an example, when the pipe diameter of the steel pipe to be fixed is large, the side plate 13 moves vertically upward relative to the connecting block 12, and simultaneously the side plate 13 moves horizontally leftward relative to the connecting block 12. When the pipe diameter of the steel pipe needs to be fixed to be small, the side plate 13 moves vertically downwards relative to the connecting block 12, and meanwhile, the side plate 13 moves horizontally rightwards relative to the connecting block 12.

In the present embodiment, the two clamping grooves 20 are used for clamping steel pipes, and for convenience of description, the left clamping groove 20 is used as a first clamping groove, the steel pipe therein is used as a first steel pipe, the right clamping groove 20 is used as a second clamping groove, and the steel pipe therein is used as a second steel pipe. When the pipe diameter of the first steel pipe and the pipe diameter of the second steel pipe are increased, the distance between the axis of the first steel pipe and the connecting block 12 and the distance between the axis of the second steel pipe and the connecting block 12 are increased, namely, the clamping point of the first steel pipe on the second pressing surface 111 moves leftwards relative to the connecting block 12, the clamping point of the second steel pipe on the second pressing surface 111 moves rightwards relative to the connecting block 12, and further the distance between the axis of the first steel pipe and the axis of the second steel pipe is increased. On the contrary, if the pipe diameter of the first steel pipe and the pipe diameter of the second steel pipe are both reduced, the distance between the axis of the first steel pipe and the axis of the second steel pipe is reduced.
