[0034] As shown in Figures 1 to 4 The utility model provides a kind of pipe row fixed device, which includes at least two pipe clamps 1 and locking assembly 2, pipe clamp 1 includes arc-shaped clamping plate 11, and the both ends of arc-shaped clamping plate 11 extend to form end plate 12 along the length direction, and arc-shaped clamping plate 11 is used to abut with pipeline 100;Locking assembly 2 includes fixed plate 21, and first slot 211 is provided on fixed plate 21, and end plate 12 is inserted into first slot 211, and fixed plate 21 is fixedly connected with end plate 12, and fixed plate 21 is abutted on the side of pipeline 100 away from arc-shaped clamping plate 11.In the embodiment, since pipe clamp 1 includes arc-shaped clamping plate 11, arc-shaped clamping plate 11 is used to abut with pipeline 100, and fixed plate 21 is abutted on the side of pipeline 100 away from arc-shaped clamping plate 11, so arc-shaped clamping plate 11 and fixed plate 21 can be fixed on pipeline 100 from both sides of pipeline 100;Since the pipe row fixed device includes at least two pipe clamps 1, and the end plate 12 of each pipe clamp 1 is fixedly connected with fixed plate 21, the relative position between all pipe clamps 1 remains fixed, and the pipe row can be positioned to ensure the stability of the distance between the pipe rows;Since first slot 211 is formed in fixed plate 21, and the end plate 12 of pipe clamp 1 is inserted into first slot 211, fixed plate 21 can enhance the limiting effect on pipe clamp 1, thereby further improving the reliability of the connection between the two;At the same time, since the end plate 12 is inserted into the first slot 211, the contact area between the end plate 12 and the fixed plate 21 is increased, thereby improving the stability of the connection between the fixed plate 21 and the pipe clamp 1.

[0035] Specifically, the pipe row spacing fixing device is used for fixing the distance between a plurality of spaced pipe rows, each pipe row is composed of a plurality of pipes 100 arranged in sequence, the pipes 100 are vertically arranged, and the axial direction of the pipes 100 is the vertical direction; each pipe clamp 1 of the pipe row spacing fixing device is arranged on the pipe 100 at the end of each pipe row, and the relative position between the pipe rows is kept fixed by the pipe clamp 1. It can be understood that the number of pipe clamps 1 and the number of first insertion slots 211 on the fixing plate 21 can be set according to the number of pipe rows, for example, if the pipe row spacing fixing device needs to fix six pipe rows, then the pipe clamp 1 is provided with six pipe clamps, and the fixing plate 21 is provided with 12 first insertion slots 211. As shown in Figure 3 and Figure 4 the fixing plate 21 is a flat plate structure, the fixing plate 21 is arranged in parallel to the vertical direction, the fixing plate 21 is provided with the first insertion slot 211, the width of the first insertion slot 211 matches the thickness of the end plate 12 of the pipe clamp 1, and the first insertion slot 211 extends upward to the upper end surface of the fixing plate 21. When installing, the construction personnel first sleeves the pipe clamp 1 on the pipe 100 at the end of the pipe row, then aligns the end plate 12 of the pipe clamp 1 with the first insertion slot 211 on the fixing plate 21, and moves the pipe clamp 1 downward, so that the end plate 12 is inserted into the first insertion slot 211, when the end plate 12 is inserted into the first insertion slot 211, the fixing plate 21 abuts against the pipe 100, so that the pipe 100 is limited in the space formed between the fixing plate 21 and the arc-shaped clamp plate 11 along the radial direction; then the construction personnel welds the joint between the first insertion slot 211 and the end plate 12, so as to fix and connect the pipe clamp 1 and the fixing plate 21 on the pipe 100.

[0036] Further, as shown in Figure 4 the locking assembly 2 further comprises a locking plate baffle 22, the locking plate baffle 22 is fixedly connected to the fixing plate 21, the first insertion slot 211 extends to the edge of the fixing plate 21, the locking plate baffle 22 is arranged on the fixing plate 21 opposite to the first insertion slot 211, and when the end plate 12 is inserted into the first insertion slot 211, the end plate 12 can abut against the locking plate baffle 22; specifically, the two ends of the locking plate baffle 22 are connected to the upper end surfaces of the fixing plate 21 on both sides of the first insertion slot 211, and the middle part of the locking plate baffle 22 is opposite to the first insertion slot 211, so as to block the first insertion slot 211, preventing the pipe clamp 1 and the fixing plate 21 from being separated along the vertical direction, and at the same time, the locking plate baffle 22 can structurally reinforce the two ends of the first insertion slot 211 on the fixing plate 21, preventing the first insertion slot 211 of the fixing plate 21 from being torn due to stress concentration.

The support 3 can be a round steel pipe or a square steel pipe, as long as it can be welded to the pipeline 100 and stably support the fixed plate 21.

[0041] Further, as shown in Figure 1 , Figure 2 and Figure 4 , the end plate 12 is provided with a second slot 121, and the second slot 121 is arranged opposite to the first slot 211. When the end plate 12 is inserted into the first slot 211, the fixed plate 21 is inserted into the second slot 121, and the second slot 121 is welded to the joint between the fixed plate 21, thereby increasing the contact area and the joint length of the fixed plate 21 and the end plate 12 without adding additional structures, and further improving the connection strength and stability of the fixed plate 21 and the pipe clamp 1.

[0045] The installation process of the pipe row fixing device provided by the embodiment is as follows:

[0046] First, the support 3 is welded on the pipeline 100, the fixed plate 21 is abutted against the side wall of the pipeline 100, then the second slot 121 of the end plate 12 is aligned with the first slot 211 of the fixed plate 21, and the pipe clamp 1 is moved downward, so that the end plate 12 is inserted into the first slot 211, at this time, the fixed plate 21 is also inserted into the second slot 121, then the seams between the first slot 211 and the end plate 12 and the seams between the second slot 121 and the fixed plate 21 are welded, and then the arc-shaped clamping plate 11 and the fixed plate 21 are clamped on the pipeline 100 from both sides of the pipeline 100. Then, the lock plate 22 is welded on the fixed plate 21 on both sides of the first slot 211 to block the first slot 211, and then the installation of the pipe row fixing device is completed.
