Referring to fig. 1, the present application provides a pipe positioning device, which includes a mounting frame 1, a plurality of adjusting rods 2, a plurality of arc clamping members 3 and a plurality of elastic press-fitting assemblies 4; the adjusting rods 2 are respectively connected with the arc clamping pieces 3, and all the arc clamping pieces 3 are distributed around the annular row of the pipeline to be installed, so that the pipeline to be installed is surrounded; the adjusting rods 2 are movably connected to the mounting frame 1, and when the adjusting rods 2 are driven to move relative to the mounting frame 1, the adjusting rods 2 can drive all the arc clamping pieces 3 to be closed and dispersed relative to a pipeline to be mounted; the elastic press-fit assembly 4 is arranged between the mounting frame 1 and the arc-shaped clamping piece 3 and is used for elastically pressing the arc-shaped clamping piece 3 towards a pipeline to be mounted.
In the pipeline positioning device, the adjusting rod 2 can drive all the arc clamping pieces 3 to be closed and dispersed, obviously, when all the arc clamping pieces 3 are closed relative to the pipeline to be installed, all the arc clamping pieces 3 are closed and press the pipeline to be installed, and in terms of the angle, the arc clamping pieces 3 are suitable for clamping the pipeline to be installed with smaller diameter; when all the arc-shaped clamping pieces 3 are dispersed relative to the pipeline to be installed, and in terms of changing angles, the arc-shaped clamping pieces 3 are suitable for clamping the pipeline to be installed with larger diameter.
When the pipeline positioning device is used for positioning and clamping the pipeline to be installed, the adjusting rod 2 can adjust the size of the surrounding area of all the arc clamping pieces 3, the pipeline to be installed with different sizes is clamped by the arc clamping pieces 3, the elastic press-fit assembly 4 can continuously apply elastic pressure to the pipeline to be installed, the pipeline to be installed has a buffering effect, the interaction force of the arc clamping pieces 3 and the pipeline to be installed can be improved, the stability of the pipeline positioning device is improved, and the pipeline to be installed is prevented from being separated from the pipeline positioning device. In this pipeline positioner, arc folder 3 and elasticity pressure equipment subassembly 4 pass through mounting bracket 1 and assemble simultaneously in the week side of treating the installation pipeline, and the process of adjusting arc folder 3 is also just the process of adjusting elasticity pressure equipment subassembly 4, therefore mounting bracket 1, arc folder 3 and elasticity pressure equipment subassembly 4 can exert the location installation effect of treating the installation pipeline jointly, improves pipeline positioner's wholeness and stability.
The pipe positioner provided in the present application will be further described with reference to the accompanying drawings and embodiments.
In some embodiments, the elastic press-fit assembly 4 is in contact with the end of the arc-shaped clamping piece 3 along the arc length direction, and is used for pressing the end of the arc-shaped clamping piece 3 along the arc length direction, so that the end of the arc-shaped clamping piece 3 along the arc length direction presses the pipeline to be installed. For a single arc-shaped clamp 3, two elastic press-fit assemblies 4 can be used to press the two ends of the arc-shaped clamp 3 along the arc length direction.
The pipe locating device can be used for clamping pipes to be installed in different sizes. Obviously, when all the arc-shaped clamping pieces 3 are closed to be abutted against each other, the size of the surrounding area of all the arc-shaped clamping pieces 3 corresponds to the minimum size of the pipeline to be installed, and at this time, the inner side surface of any one of the arc-shaped clamping pieces 3 is abutted against the pipeline surface of the pipeline to be installed everywhere. In order to clamp a larger-sized pipe to be installed, all the arc-shaped clamps 3 need to be properly dispersed under the driving of the adjusting lever 2, and at this time, the entire inner side surface of the arc-shaped clamps 3 cannot be completely abutted against the pipe surface of the pipe to be installed, in other words, only a portion of the inner side surface near both ends of the arc-shaped clamps 3 can be abutted against the pipe surface of the pipe to be installed. For the aforesaid assembly characteristics of arc folder 3 and the pipeline that waits to install, the pipeline positioner that this application provided makes elasticity pressure equipment subassembly 4 contact and extrudees the end along the arc length direction of arc folder 3, ensures that the effort that elasticity pressure equipment subassembly 4 applied can comprehensively, effectively act on the pipeline that waits to install.

In the elastic press-fit assembly 4, the spring 43 is in a compressed state, and thus, the spring 43 can continuously apply a pushing force to the connecting rod 42, driving the connecting rod 42 to press the arc-shaped clip 3.
In the above embodiment, the first limiting tube 41 may be provided with the limiting chute 411, the rod end of the connecting rod 42 may be provided with the connecting slider 421, the connecting slider 421 is embedded in and slidably mounted in the limiting chute 411, and the spring 43 pushes the connecting rod 42 and the arc-shaped clip 3 through the connecting slider 421.
Referring to fig. 1 and 3, as for the adjusting rod 2 of the pipe positioner, it may include a screw 21 penetrating and screwed to the mounting bracket 1. When the adjusting rod 2 is used for driving the arc clamping piece 3 to move, an operator can screw the screw rod 21, so that the screw rod 21 can do spiral motion relative to the mounting frame 1, the screw rod 21 can directly or indirectly lean against the arc clamping piece 3, and linear displacement generated when the screw rod 21 does spiral motion can be transmitted to the arc clamping piece 3 to drive the arc clamping piece 3 to be close to a pipeline to be mounted.
Furthermore, in the above-described embodiment, the adjustment lever 2 further includes the fixing lever 22; one end of the fixing rod 22 is fixed on the arc-shaped clamping piece 3, the other end of the fixing rod 22 is abutted against the screw rod 21, and therefore, the screw rod 21 is indirectly abutted against the arc-shaped clamping piece 3 through the fixing rod 22, and therefore, linear displacement generated when the screw rod 21 performs spiral motion is firstly transmitted to the fixing rod 22 and then transmitted to the arc-shaped clamping piece 3 through the fixing rod 22.
In general, the diameter of the fixing rod 22 may be larger than the diameter of the screw 21; the diameter of the screw rod 21 is smaller, so that the screw rod 21 and the mounting frame 1 can be conveniently assembled and connected, and the diameter of the fixing rod 22 is larger, so that the stability of the movement of the screw rod 21 and the fixing rod 22 can be improved.
In the above embodiment, the mounting frame 1 may be provided with the second limiting tube 5, and the limiting slider 221 of the fixing rod 22 penetrates into and is slidably connected to the second limiting tube 5. The second limiting tube 5 may restrict the movement direction and the movement range of the limiting slider 221, and thus the movement direction and the movement range of the fixing lever 22. In addition, the mounting frame 1 can further comprise a limit sliding rod 23, the limit sliding rod 221 is sleeved and connected to the limit sliding rod 23 in a sliding manner, and the limit sliding rod 23 can play a guiding role on the limit sliding rod 221.

As described above, for pipes to be installed of different sizes, the arc-shaped clamp 3 clamps the pipe to be installed mainly with both ends in the arc length direction thereof, and for this reason, the wall thickness of the middle part of the arc-shaped clamp 3 in the arc length direction is larger than the wall thickness of both ends in the arc length direction. The wall thickness of the middle part of the arc-shaped clamping piece 3 along the arc length direction is relatively large, so that the structural strength of the local part of the arc-shaped clamping piece 3 can be improved, and the arc-shaped clamping piece 3 is prevented from being damaged by the adjusting rod 2; the wall thickness of the two ends of the arc-shaped clamping piece 3 along the arc length direction is smaller, so that the arc-shaped clamping piece 3 is beneficial to deforming and extruding a pipeline to be installed.
Referring to fig. 1, in some embodiments, the mounting bracket 1 of the pipe positioner may include a first mounting bracket 11 and a second mounting bracket 12 for enclosing a pipe to be installed; at the same time, two arc-shaped clamping members 3 are respectively arranged on the inner side of the first mounting frame 11 and the inner side of the second mounting frame 12.
When the pipeline positioning device is used for positioning and installing a pipeline to be installed, an operator can surround the pipeline to be installed by the first installation frame 11 and the second installation frame 12 and is fixed on the periphery of the pipeline to be installed, at the moment, the arc clamping piece 3 arranged on the inner side of the first installation frame 11 and the arc clamping piece 3 arranged on the inner side of the second installation frame 12 naturally surround the pipeline to be installed, then the operator can adjust the adjusting rod 2 according to the size of the pipeline to be installed, the adjusting rod 2 drives the arc clamping piece 3 to be close to and extrude the pipeline to be installed, and all the arc clamping pieces 3 surround and clamp the pipeline to be installed.
In the above embodiment, the joint of the first mounting frame 11 and the second mounting frame 12 is provided with the connection block 6 and the locking bolt 7, and after the first mounting frame 11 and the second mounting frame 12 are wrapped around the pipe to be installed and fixed on the peripheral side of the pipe to be installed, the operator can wear and lock the connection block 6 by using the locking bolt 7, thereby fixedly connecting the first mounting frame 11 and the second mounting frame 12.
