Description

Technical Field

[0001] The present application relates to the technical field of double-layer pipes, and in particular to a support structure for double-layer pipe processing. Background Art

[0002] Double-layer pipe is a double-layer pipe divided into an inner layer and an outer layer. The inner and outer layers are often made of different materials or the same material with a filler or gap in the middle to achieve higher strength, high thermal insulation, high heat preservation, and high airtightness. Double-layer pipes have more physical and chemical properties than single-layer pipes, and have a wider range of uses and applicable environments. They have excellent performance and can meet the requirements of transporting ultra-high temperature liquid gas, transporting high-pressure liquid gas, as well as thermal insulation, outer layer anti-scalding, and inner layer thermal insulation. They can also meet the special requirements of corrosive materials, where the inner layer is made of anti-corrosion material and the outer layer protects the inner layer.

[0003] During the processing of double-layer pipes, limited support and fixation are required. In order to facilitate the limited support and fixation of the double-layer pipes, the present application proposes a support structure for double-layer pipe processing. Utility Model Content

[0004] In order to facilitate the limiting support and fixation of the double-layer pipe, the present application provides a support structure for double-layer pipe processing.

[0007] The arc-shaped clamping blocks are arranged in pairs, and multiple pairs of the arc-shaped clamping blocks are arranged in sequence along the length direction of the mounting rod. The two arc-shaped clamping blocks of the same pair are arranged opposite to each other, and the two arc-shaped clamping blocks of the same pair are respectively fixedly connected to the two mounting rods.

[0008] By adopting the above technical solution, when the double-layer tube needs to be limited and fixed, the double-layer tube is placed between the arc-shaped clamping blocks, and then the two mounting rods are driven by the driving assembly to slide in the direction of approaching each other, thereby driving the two relatively arranged arc-shaped clamping blocks to slide in the direction of approaching each other, and then clamping the double-layer tube to achieve limited support and fixation of the double-layer tube. The operation is simple and convenient, thereby facilitating the processing of the double-layer tube.

[0009] Optionally, the driving assembly includes a rotating motor, a driving gear and a driven rack, the driving gear is fixedly connected to the rotating shaft of the rotating motor, and two driven racks are provided, the two driven racks are respectively meshed with the two radial sides of the driving gear, and the two ends of the two driven racks far away from each other are respectively fixedly connected to the bottom ends of two mounting rods.

[0011] Optionally, a first clearance slot is provided on the mounting rod connected to the driven rack located below, and the driven rack located above can slide to pass through the first clearance slot.

[0012] By adopting the above technical solution, the length of the driven rack can be increased, and at the same time, the driven rack will not interfere with the mounting rod. When the two arc-shaped clamping blocks move away from each other, the distance between the two arc-shaped clamping blocks can be made larger, thereby leaving enough space to place the double-layer tube between the two arc-shaped clamping blocks.

[0013] Optionally, a protective cover is fixedly mounted on the mounting frame, the middle portion of the driven rack and the driving gear are located inside the protective cover, and two second clearance slots for the driven rack to pass through are provided on two opposite side walls of the protective cover.

[0014] By adopting the above technical solution, the protective cover can shield the driving gear, and while protecting the driving gear, it also plays a role in preventing the staff from being scratched by the driving gear, thereby increasing safety.

[0015] Optionally, a first T-rod is fixedly connected to the side of the driven rack away from the driving gear, and a first T-groove for the T-rod to pass through is formed on the inner wall of the second clearance groove away from the driving gear, and the first T-groove runs through both sides of the protective cover.

[0017] Optionally, a T-block is fixedly connected to the top end of the mounting rod, and a second T-slot for the T-block to slide is provided on the mounting frame.

When the double-layer tube needs to be limited and fixed, the double-layer tube is placed between the arc-shaped clamping blocks, and then the two mounting rods are driven to slide toward each other through the driving assembly, thereby driving the two relatively arranged arc-shaped clamping blocks to slide toward each other, and then the double-layer tube is clamped to achieve the limited support and fixation of the double-layer tube. The operation is simple and convenient, thus facilitating the processing of the double-layer tube;

[0023] 2. When the arc-shaped clamping block needs to slide, start the rotating motor, and through the cooperation of the driving gear and the driven rack, drive the two mounting rods to slide towards or away from each other, which is simple and convenient to operate;

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The present application embodiment discloses a support structure for double-layer pipe processing. Figure 1-5 The support structure for double-layer pipe processing includes a support structure for double-layer pipe processing, including a mounting frame, a mounting rod, an arc-shaped clamping block and a driving assembly. The mounting rod is vertically arranged, and two mounting rods are arranged in parallel. One end of the mounting rod is slidably connected to the mounting frame, and the other end of the mounting rod is connected to the driving assembly. The driving assembly is used to drive the two mounting rods to slide in a direction close to or away from each other. The arc-shaped clamping blocks are arranged in pairs, and multiple pairs of arc-shaped clamping blocks are arranged in sequence along the length direction of the mounting rod. The two arc-shaped clamping blocks of the same pair are arranged opposite to each other, and the two arc-shaped clamping blocks of the same pair are respectively fixedly connected to the two mounting rods. The sizes of the multiple pairs of arc-shaped clamping blocks decrease from top to bottom. In this embodiment, two pairs of arc-shaped clamping blocks are arranged, which is convenient for adapting to the processing of double-layer pipes of different sizes and has high applicability.

[0033] When the double-layer tube needs to be limited and fixed, the double-layer tube is placed between the arc-shaped clamping blocks, and then the two mounting rods are driven by the driving assembly to slide in the direction of approaching each other, thereby driving the two relatively arranged arc-shaped clamping blocks to slide in the direction of approaching each other, and then the double-layer tube is clamped, thereby achieving limited support and fixation of the double-layer tube. The operation is simple and convenient, thereby facilitating the processing of the double-layer tube.

[0034] The driving assembly includes a rotating motor, a driving gear and a driven rack. The driving gear is fixedly connected to the rotating shaft of the rotating motor. Two driven racks are provided. The two driven racks are respectively engaged with the two radial sides of the driving gear. The two ends of the two driven racks that are far away from each other are respectively fixedly connected to the bottom ends of the two mounting rods. When the arc-shaped clamping block needs to slide, the rotating motor is started, and the two mounting rods are driven to slide in the direction of approaching or moving away from each other through the cooperation of the driving gear and the driven rack. The operation is simple and convenient.

[0035] A first clearance slot is provided on the mounting rod connected to the driven rack located below, and the driven rack located above can slide through the first clearance slot. The length of the driven rack can be increased, and the driven rack does not interfere with the mounting rod. When the two arc-shaped clamping blocks move away from each other, the distance between the two arc-shaped clamping blocks can be increased, thereby leaving enough space to place the double-layer pipe between the two arc-shaped clamping blocks.

[0036] A protective cover is fixedly installed on the mounting frame, and the middle part of the driven rack and the driving gear are located inside the protective cover. Two second clearance slots for the driven rack to pass through are provided on the two opposite side walls of the protective cover. The protective cover can shield the driving gear. While protecting the driving gear, it also plays a role in preventing the staff from being scratched by the driving gear, thereby increasing safety. A first T-bar is fixedly connected to the side of the driven rack away from the driving gear, and a first T-slot for the T-bar to pass through is provided on the inner wall of the second clearance slot away from the driving gear. The first T-slot runs through both sides of the protective cover. This helps to improve the meshing stability between the driving gear and the driven rack. A T-block is fixedly connected to the top of the mounting rod, and a second T-slot for the T-block to slide is provided on the mounting frame, which helps to improve the sliding stability of the top of the mounting rod.

[0037] The implementation principle of a support structure for double-layer tube processing in an embodiment of the present application is as follows: when the double-layer tube needs to be limited and fixed, the double-layer tube is placed between the arc-shaped clamping blocks, and then the two mounting rods are driven to slide toward each other through the driving assembly, thereby driving the two relatively arranged arc-shaped clamping blocks to slide toward each other, and then the double-layer tube is clamped, thereby achieving limited support and fixation of the double-layer tube. The operation is simple and convenient, thereby facilitating the processing of the double-layer tube.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
