Description

Technical Field

[0001] This utility model relates to the field of support devices, and in particular to a pipe support device for water supply and drainage. Background Technology

[0002] Drainage pipes primarily handle the drainage of rainwater, sewage, and agricultural irrigation. Common types include PVC pipes, cast iron drainage pipes, PP silent drainage pipes, and galvanized iron pipes. Drainage pipelines are pipe systems that collect and discharge sewage, wastewater, and rainwater, including main pipes and branch pipes. They are mainly used for building drainage, urban infrastructure, road construction, and specific engineering scenarios. During the construction of water supply and drainage projects, multiple pipes need to be welded together. To ensure that the centerlines of each pipe are collinear, the pipes need to be supported to ensure the accuracy of the pipe connections.

[0003] In existing technologies, pipe support devices are often used to support pipes to ensure that the installation requirements of the device are met. Since the support points of each pipe are far apart, common pipe supports are equipped with casters to reduce the friction between the device and the ground, thereby making it easier for workers to move the device. However, during the pipe support process, the casters will move during construction, affecting the construction accuracy. It is foreseeable that a way to switch the device from a mobile state to a fixed state can be achieved. Utility Model Content

The end of the limiting slide facing the base is connected to the optical shaft, and the sleeve is provided on the base. The sleeve and the optical shaft are coaxially arranged.

[0008] As a preferred technical solution of the pipe support device for water supply and drainage of this utility model, a first compression spring is sleeved on the optical shaft, and the two ends of the first compression spring are respectively connected to the sleeve and the limiting slide.

[0009] As a preferred technical solution of the pipe support device for water supply and drainage of this utility model, the two limiting slides are connected by a connecting rod, and a pedal is connected to one of the limiting slides.

Detailed Implementation

[0026] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0027] This application includes a base 1 for supporting the entire device, and four casters 11 are provided at the end of the base 1 facing the ground, the casters 11 being as follows: Figure 1 The figures are symmetrically arranged at the four ends of the base 1, and the two ends of the base 1 are symmetrically arranged as shown. Figure 4 The support rod 2 shown is used to switch the device from a mobile state to a fixed state. The support rod 2 is hinged to the base 1 via a hinge frame 12. The support rod 2 is as follows... Figure 6 The outer contour shown is L-shaped. The support rod 2 rotates radially about the axis of the hinge frame 12 as a reference line. The support rod 2 passes through... Figure 5As shown in the through hole 13, when the support rod 2 is in the initial position, one end of the support rod 2 is connected to the hinge frame 12, and the other end is located at the bottom of the base 1 and passes through the through hole 13. During the movement of the device, the four universal wheels 11 push the device to move, reducing the friction between the device and the ground. When it is necessary to clamp and fix the target pipe, push the two support rods 2 to rotate around the hinge frame 12 as a reference, so that the support rods 2 contact the ground and continue to rotate until they are completely in contact with the ground. The support rods 2 support the base 1, and the universal wheels 11 are disengaged from the ground, increasing the friction between the device and the ground and preventing the device from becoming unstable during the process of supporting the pipe.

[0028] A driving structure is connected between the two support rods 2, as shown in the driving structure... Figure 6 The diagram shows a limiting slide 23 and a slider 21. Slider 21 is symmetrically arranged at both ends of the support rod 2. The slider 21 is hinged to the support rod 2 via a hinge shaft 22, which is fixed to the support rod 2. There are two limiting slides 23, which are symmetrically arranged at both ends of the support rod 2. The slider 21 is slidably connected in the corresponding limiting slide 23. The two limiting slides 23 are connected by a connecting rod 24. The bottom end of the limiting slide 23 is connected to the optical axis 27. The base 1 is provided with sleeves 26, the number of which is the same as the number of optical axes 27. The sleeves 26 are coaxially arranged with the corresponding optical axes 27. A first compression spring is sleeved on the optical axis 27. The two ends of the first compression spring are connected to the sleeves 26 and the limiting slide 23 respectively. By pressing down the two limiting slides 23, the connected support rods 2 are driven to rotate in the same direction. During the rotation of the two support rods 2, the connected sliders 21 are driven to move in the horizontal direction, so that the distance between the two sliders 21 increases. The first compression spring contracts to generate a reverse force to push the limiting slide 23 to reset. A pedal 25 is connected to the connecting rod 24 to facilitate the user to drive and press down.

[0029] To further ensure the stability of the device support, a locking structure is connected to the base 1. The locking structure includes a locking part 28 and a driven part 32. The locking part 28 is connected to a connecting rod 24. The locking part 28 is a rectangle that gradually narrows from top to bottom. During the downward pressing of the limiting slide 23, the locking part 28 moves in the same direction. The driven parts 32 are symmetrically arranged at both ends of the locking part 28. The driven parts 32 are slidably connected to the base 1 through a sliding groove 14. A limiting rod for supporting the height of the driven part 32 is provided in the sliding groove 14. The limiting rod passes through the driven part 32 so that it can move in the axial direction of the limiting rod. When the locking part 28 moves downward to the point where its top end contacts the bottom end of the driven part 32, it pushes the two driven parts 32 to move towards each other, shortening the distance between the two driven parts 32, thereby restricting the upward movement of the locking part 28 and ensuring that the support rod 2 can remain in contact with the ground. A second compression spring is sleeved on the limiting rod. The two ends of the second compression spring are connected to the sliding groove 14 and the driven part 32, respectively. The second compression spring drives the driven part 32 to move, shortening the distance between the two driven parts 32 and preventing the locking part 28 from moving upwards. Simultaneously, to facilitate the operator switching the device from a fixed state to a movable state, a sliding connection is provided on the base 1 as follows... Figure 7 The drive unit 3 shown has a transmission unit 31 connected to it. The two ends of the transmission unit 31 are respectively attached to two driven parts 32. The end faces of the transmission unit 31 and the driven parts 32 are inclined. During the movement of the drive unit 3, the transmission unit 31 can drive the two driven parts 32 to move to both ends of the device respectively, so that the bottom end of the driven part 32 is separated from the top end of the locking part 28. The locking part 28 moves upward by the power provided by the first compression spring, thereby driving the connected limiting slide 23 to move in the same direction, thereby driving the support rod 2 to rotate upward and separate the support rod 2 from the ground, and the universal wheel 11 contacts the ground.

[0030] A support part 4 is connected to the base 1 shown. The support part 4 is used to support the bottom end of the target pipe. The center of the support part 4 has an arc-shaped hollow design to increase its contact area with the pipe. A clamping part 41 is hinged to the support part 4. The support part 4 and the clamping part 41 overlap to form a cavity for clamping the pipe, thereby completing the support of the target pipe. The support part 4 and the clamping part 41 are connected by a fixing component. The fixing component is usually a bolt and nut assembly depending on the anchoring situation. The support part 4 is connected to the base 1 by a push rod, which allows the height of the device to be adjusted according to the installation requirements of the pipeline. At the same time, the hinged connection between the support part 4 and the clamping part 41 facilitates the separation of the device from the pipeline after the pipeline welding is completed.
