Description

Technical Field

[0001] The utility model relates to the technical field of alignment for pipeline flange installation, in particular to an alignment and positioning device for pipeline flange installation. Background Art

[0002] Flowmeter flange is a flange connection device used to install flowmeter. In the industrial field, flowmeter is usually used to measure the flow rate of fluid (liquid or gas) through the pipeline in order to monitor and control the fluid flow. In order to correctly install the flowmeter in the pipeline system, a flowmeter flange is required.

[0003] The existing flow meter flange needs to be pre-aligned during installation so that the bolts can be smoothly inserted into the threaded holes on the flange. During the alignment of the flow meter flange, multiple people usually use a crowbar to insert the bolt holes for alignment, which easily makes the alignment and positioning of the pipeline flange time-consuming and laborious.

[0004] Therefore, an alignment and positioning device for pipe flange installation is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an alignment and positioning device for pipe flange installation in order to solve the above problems, thereby improving the problem that the alignment and positioning of the pipe flange is time-consuming and labor-intensive.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: an alignment and positioning device for pipeline flange installation, comprising: a flow meter flange, one end of the flow meter flange is provided with a pipeline flange; an alignment mechanism, the alignment mechanism is arranged on the surface of the pipeline flange; wherein the alignment mechanism comprises an alignment box arranged on the upper end of the pipeline flange surface, one side of the alignment box is fixedly connected with a round rod, the surface of the round rod is fixedly connected with a soft sleeve, the top of the alignment box is fixedly connected with a hydraulic cylinder, the inner wall of the hydraulic cylinder is slidably connected with a hydraulic rod, the bottom end of the hydraulic rod is fixedly connected with a push block, the top of the alignment box is fixedly connected with a hydraulic box, one side of the hydraulic box is connected with the inner wall of the hydraulic cylinder, and the inner wall of the hydraulic box is slidably connected with a liquid push rack. By using round rods, soft sleeves and alignment boxes, the fixing rod can be inserted into the threaded hole of the flange. By using the hydraulic box, hydraulic pusher, hydraulic cylinder and hydraulic rod, one person can quickly align the pipeline flange with the flowmeter flange. Aligning and positioning the pipeline flange is more convenient and saves time and effort. By using the soft sleeve, the threaded hole is protected and the wear of the fixing rod directly on the threaded hole is reduced.

[0007] Preferably, the inner wall of the alignment box is slidably connected to a limit block, the rear end of the alignment box is fixedly connected to a mounting frame, the inner wall of the mounting frame is slidably connected to a mounting block, the inner wall of the mounting frame is rotatably connected to a screw rod, and the inner wall of the mounting block is threadedly connected to the surface of the screw rod. The screw rod, the mounting block and the limit block are used to realize the installation of the alignment mechanism on the pipeline flange, thereby ensuring that the pipeline flange is aligned with the flow meter flange by a single person, thereby ensuring the safety of aligning the pipeline flange.

[0008] Preferably, one side of the alignment box is provided with fixing grooves distributed in equal rows.

[0009] Preferably, the inner wall of the limit block is slidably connected with a fixing rod, and the surface of the fixing rod is clamped to the inner wall of one of the fixing grooves. The fixing rod and the fixing groove are used to fix the limit block after the position adjustment in the alignment box, ensuring that the limit block can contact pipes of different diameters.

[0010] Preferably, a positioning ring is fixedly connected to the inner wall of the hydraulic cylinder. The positioning ring is used to limit the upward movement of the hydraulic rod, thereby preventing the hydraulic rod from being higher than the liquid outlet end of the hydraulic box during the upward movement.

[0012] Preferably, a soft block is fixedly connected to the top of the mounting block and one side of the mounting frame.

[0013] Preferably, the limit block is a rubber component. By using the limit block of the rubber component and the soft block on the mounting block and mounting frame, the alignment mechanism can be flexibly mounted on the surface of the pipe flange, thereby preventing the alignment mechanism from being fixed on the surface of the pipe flange with too much force, thereby damaging the paint surface on the pipe flange.

[0014] The beneficial effects of the utility model are:

[0015] 1. The round rod, soft sleeve and alignment box are used to insert the fixed rod into the threaded hole of the flange. The hydraulic box, hydraulic pusher, hydraulic cylinder and hydraulic rod are used to quickly align the pipeline flange and the flow meter flange by one person. It is more convenient to align and position the pipeline flange, saving time and effort. The soft sleeve is used to protect the threaded hole and reduce the wear of the fixed rod directly on the threaded hole.

[0016] 2. The alignment mechanism is installed on the pipe flange by using a screw rod, a mounting block and a limit block, thereby ensuring that the pipe flange is aligned with the flow meter flange by a single operator, thereby ensuring the safety of aligning the pipe flange.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4 As shown, an alignment and positioning device for pipeline flange installation comprises: a flow meter flange 1, one end of which is provided with a pipeline flange 2; an alignment mechanism 3, which is arranged on the surface of the pipeline flange 2; wherein the alignment mechanism 3 comprises an alignment box 31 arranged on the upper end of the surface of the pipeline flange 2, one side of the alignment box 31 is fixedly connected to a round rod 315, the surface of the round rod 315 is fixedly connected to a soft sleeve 32, the top of the alignment box 31 is fixedly connected to a hydraulic cylinder 33, and the inner wall of the hydraulic cylinder 33 is slidably connected to a hydraulic rod 315. 4.

The interior of the hydraulic box 36 is filled with hydraulic oil.

[0024] When the pipeline flange 2 and the flow meter flange 1 need to be installed, the mounting frame 38 is pushed so that the soft block on the mounting frame 38 contacts the pipeline flange 2, the handle 316 is moved by hand so that the soft sleeve 32 passes through the threaded holes corresponding to the flow meter flange 1 and the pipeline flange 2, and the alignment box 31 is installed on the pipeline flange 2, and the liquid pushing frame 37 is pushed. The liquid pushing frame 37 moves in the hydraulic box 36 so that the hydraulic oil in the hydraulic box 36 is pushed into the hydraulic cylinder 33. The excessive hydraulic oil in the hydraulic cylinder 33 pushes the hydraulic rod 34 downward, and the downward movement of the hydraulic rod 34 pushes the push block 35 downward, and the downward movement of the push block 35 pushes the pipeline flange 2 downward, so that the bottom of the push block 35 contacts the upper surface of the flow meter flange 1, and the pushing of the liquid pushing frame 37 is stopped so that the pipeline flange 2 and the flow meter flange 1 are relatively aligned. At this time, the bolts are inserted into the threaded holes for installation.

The excessive hydraulic oil in the hydraulic cylinder 33 pushes the hydraulic rod 34 downward, and the downward movement of the hydraulic rod 34 pushes the push block 35 downward, and the downward movement of the push block 35 pushes the pipe flange 2 downward, so that the bottom of the push block 35 contacts the upper surface of the flow meter flange 1, stop pushing the liquid pushing rack 37, so that the pipe flange 2 is aligned with the flow meter flange 1, and at this time, insert the bolts into the threaded holes for installation.

[0028] It should be noted that the flow meter flange 1 and the pipe flange 2 in the above description are relatively mature devices in the existing technology. The specific models can be selected according to actual needs and will not be described in detail here.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
