Description

Technical Field

[0001] This utility model belongs to the field of line construction technology, specifically a pipeline positioning device. Background Technology

[0002] The main function of power line conduits is to protect wires and cables. By encasing wires and cables in residential and commercial buildings, outdoors, and in some special environments, power line conduits ensure that wires are not damaged when passing through walls, floors, and other structures. At the same time, they prevent wires from being exposed, reduce safety hazards, and resist the corrosion of cables by factors such as underground damp environments and corrosive soil, thus ensuring the stability and safety of power transmission.

[0003] During the laying of conduits, the direction of the line must first be determined, and the two intersecting conduits must be cut at a certain angle, which requires the use of positioning components.

[0004] Among the applications found, one application with application number 202222546961.5 describes a cutting device for PVC electrical conduit. This novel device uses sliding rods to support clamping frames at both ends. The clamping distance between the two clamping frames can be adjusted according to the diameter of the PVC electrical conduit to be cut, facilitating the fixation of the PVC electrical conduit and ensuring cutting stability. When the clamping frames approach the outer wall of the PVC electrical conduit, the PVC electrical conduit adjusts and contacts the ball bearings. The ball bearings roll within the arc-shaped clamping groove, accelerating the movement of the PVC electrical conduit and thus facilitating the adjustment of the cutting length. However, the following shortcomings exist:

[0005] This device is suitable for pre-cutting conduits, but not for on-site cutting. In on-site operations, when two conduits cross, the angle may not be 90° or other degrees, resulting in a certain error that causes the cut angles to be mismatched. This indirectly affects the installation of the expansion sleeve at the connection of the two pipe ends. Therefore, in order to avoid this error, an on-site cutting and positioning device is designed. Utility Model Content

[0006] The purpose of this utility model is to provide a conduit positioning device in order to solve the above-mentioned problems.

[0007] The technical solution adopted by this utility model is as follows: a conduit positioning device includes a support base, a central column integrally provided above the middle of the support base, a positioning disk integrally provided around the outer ring of the central column, a support arm rotatably connected to the outside of the central column through the positioning disk, a first lead screw threadedly connected to the end of the support arm, a throttle handle integrally provided at the lower part of the first lead screw, a support foot connected to the bottom of the first lead screw through a ball joint, a locking component provided between the support arm and the positioning disk, and an adjustable conduit positioning component provided above the support arm.

[0008] The locking assembly includes: a groove, a guide post, an electromagnet, and a sliding lug; wherein, a groove is provided inside the support arm near the lower part of the positioning plate, a guide post is integrally provided on both sides of the groove, an electromagnet is slidably connected inside the groove, and sliding lugs are symmetrically connected to both sides of the outer shell of the electromagnet, and the sliding lugs are slidably connected to the guide post.

[0009] The pipe positioning assembly includes a movable seat, a cavity, a drive motor, a second lead screw, a guide post, a reserved notch, a first limiting seat, a first pin, a second limiting seat, a second pin, a clamp, and a third pin. The movable seat is located above the support arm. A cavity is integrally formed in the center of the bottom of the movable seat, and a drive motor is installed inside the cavity.

Clamps are movably connected above both the first and second limiting seats, and the bottoms of the first, second, and clamps are respectively embedded with a first pin, a second pin, and a third pin.

[0010] The output shaft of the drive motor is connected to the end of the second lead screw at a right angle, and the cavity extended from the second lead screw is threaded through the support arm. The guide post is slidably connected to the support arm.

[0011] The first and second pins each have four pins, arranged in a two-long-two-short configuration. The upper part of the movable seat has a reserved hole that fits with the first and second pins. The edges of the first and second limiting seats have reserved holes that fit with the third pin.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the device is placed at the intersection of two conduits. By rotating the support arm with the center of the central column as the origin, the angle of the support arm can be adjusted.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In this utility model:

[0025] Example 1:

[0026] Reference Figure 1-5A conduit positioning device includes a support base 1, a central column 101 integrally mounted on the upper part of the center of the support base 1, a positioning disk 1011 integrally mounted on the outer ring of the central column 101, a support arm 2 rotatably connected to the outside of the central column 101 via the positioning disk 1011, the angle of the support arm 2 can be adjusted by rotating the support arm 2 with the center of the central column 101 as the origin, matching the direction of the conduit, a first lead screw 201 threadedly connected to the end of the support arm 2, a handle 202 integrally mounted on the lower part of the first lead screw 201, a support foot 203 connected to the bottom of the first lead screw 201 via a ball joint, rotating the handle 202 causes the first lead screw 201 to move down, causing the support foot 203 to contact the ground, increasing the support force of the support arm 2, a locking component is provided between the support arm 2 and the positioning disk 1011, and an adjustable conduit positioning component is provided on the upper part of the support arm 2.

[0027] Furthermore, the locking assembly includes: a groove 7, a guide post 701, an electromagnet 8, and a sliding lug 801;

[0028] The support arm 2 has a groove 7 located inside near the bottom of the positioning disk 1011. Guide posts 701 are integrated on both sides of the groove 7. An electromagnet 8 is slidably connected inside the groove 7. Lugs 801 are symmetrically connected on both sides of the outer shell of the electromagnet 8. The lugs 801 are slidably connected to the guide posts 701. When the electromagnet 8 is energized by the control switch, the disk surface of the electromagnet 8 generates magnetism. It moves upward through the guide posts 701 and comes into contact with the bottom surface of the positioning disk 1011, achieving positioning without angle limitations.

[0029] Furthermore, the pipeline positioning assembly includes a movable seat 3, a cavity 301, a drive motor 302, a second lead screw 303, a guide post 304, a reserved notch 305, a first limiting seat 4, a first pin 401, a second limiting seat 5, a second pin 501, a clamp 6, and a third pin 601.

[0030] The support arm 2 has a movable seat 3 above it. The bottom center of the movable seat 3 has an integral cavity 301. The cavity 301 is equipped with a drive motor 302. The bottom of the cavity 301 is rotatably connected to a second lead screw 303. The bottom of the movable seat 3 is equipped with a guide post 304. The output shaft of the drive motor 302 is connected to the end of the second lead screw 303 at a right angle. The second lead screw 303 extends out of the cavity 301 and is threaded through the support arm 2. The guide post 304 is slidably connected to the support arm 2. The drive motor 302 is controlled by a switch to operate. Under the action of the right angle transmission, the second lead screw 303 rotates. The thread engagement drives the movable seat 3 to move upward, so that the first limit seat 4, the second limit seat 5 and the conduit come into contact.

[0031] The upper surface of the movable base 3 is embedded with a reserved notch 305. There are four first pins 401 and four second pins 501, arranged in two long and two short configurations. There are reserved holes on the upper part of the movable base 3 that fit with the first pins 401 and the second pins 501. The third pin 601 below the clamp 6 is inserted into the first limiting seat 4 and the second limiting seat 5. At this time, there is a gap between the first limiting seat 4 and the second limiting seat 5, which corresponds to the reserved notch 305. The operator can use this gap and a saw blade to cut the conduit. This design can increase the accuracy of the cut and prevent the blade from deviating.

[0032] Furthermore, the guide post 304 is designed to avoid having scale lines to aid in observing the height of the movable seat 3.

[0033] Furthermore, a first limiting seat 4 and a second limiting seat 5 are movably connected above the movable seat 3. A clamp 6 is movably connected above both the first limiting seat 4 and the second limiting seat 5. A first pin 401, a second pin 501, and a third pin 601 are respectively embedded in the bottom of the first limiting seat 4, the second limiting seat 5, and the clamp 6. A reserved hole is provided on the edge of the first limiting seat 4 and the second limiting seat 5, which fits with the third pin 601. The detachable design of the first limiting seat 4 and the second limiting seat 5 can limit the conduit of various diameters, improving the convenience of using the conduit. The first pin 401 and the second pin 501 are arranged with two long and two short pins, which has a foolproof property.

[0034] Furthermore, a switch is provided on the side of the support arm 2. The switch is connected to an external 12V portable battery through a wire. The portable battery is small in size, easy to carry and transport, and has good stability. The switch is used to control the electromagnet 8 and the drive motor 302, controlling the magnetic force output of the electromagnet 8 and the rotation of the drive motor 302.

[0035] Example 2:

[0036] Reference Figure 6 Furthermore, in addition to the embodiment in which a third pin 601 is provided at the bottom of the clamp 6, there is another embodiment in which bolts 602 are provided through both sides of the clamp 6, and the bolts 602 are threadedly connected to the reserved holes between the first limiting seat 4 and the second limiting seat 5. This design, which uses threaded connection, can make the connection between the clamp 6 and the first limiting seat 4 and the second limiting seat 5 stronger and more stable, and prevent the conduit from sticking out.

[0037] Working Principle: First, place the device at the intersection of two conduits. Then, by rotating the support arm 2, with the center of the central column 101 as the origin, the angle of the support arm 2 can be adjusted to match the direction of the conduits. Rotating the handle 202 causes the first lead screw 201 to move downwards, causing the support foot 203 to contact the ground, increasing the support force of the support arm 2. Next, place the first limit seat 4 and the second limit seat 5, which correspond to the pipe diameter, on the movable seat 3. The switch controls the operation of the drive motor 302, which, under the action of the right-angle transmission, causes the second lead screw 303 to rotate. This, in turn, uses the thread engagement to move the movable seat 3 upwards, thus... The first limiting seat 4 and the second limiting seat 5 are in contact with the conduit. After the support is in place, the electromagnet 8 is energized by the control switch. The disk surface of the electromagnet 8 generates magnetism, which moves upward through the guide post 701 and comes into contact with the bottom surface of the positioning disk 1011, achieving the purpose of positioning without angle limitation. Finally, the third pin 601 below the clamp 6 is inserted between the first limiting seat 4 and the second limiting seat 5. At this time, there is a gap between the first limiting seat 4 and the second limiting seat 5, which corresponds to the reserved notch 305. The operator can use this gap and a saw blade to cut the conduit. This design can increase the accuracy of the cut and avoid the blade from deviating.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
