Description

Technical Field

[0001] The utility model relates to the field of thermal insulation pipes, and in particular to a thermal insulation pipe threading device. Background Art

[0002] The insulation pipe is composed of an outer protective pipe, an insulation layer, and a steel pipe. During production, the steel pipe needs to be inserted into the outer protective pipe through equipment. During the insertion, several groups of support blocks need to be evenly bound on the outside of the steel pipe. Since the outer protective pipe will be deformed at the rear end after long-term storage, the support blocks often get stuck on the outer protective pipe during the insertion, which may cause damage to the outer protective pipe.

[0003] The existing solution usually adopts manual processing, which uses tools to pry up the deformed parts, and then smoothly insert each set of support blocks into the outer protective pipe. Since the equipment is in operation during prying, injuries may occur. In addition, due to the large diameter of the insulation pipe, when prying the top of the insulation pipe, it is necessary to manually go up to the upper part to operate. These situations cannot better protect the life and property safety of the operating workers. At the same time, the process is very cumbersome and cannot improve production efficiency.

An annular bracket is arranged at the feed inlet of the outer protective pipe placement rack, and a plurality of support components for expanding the outer protective pipe port are arranged in an annular shape on the outer side of the annular bracket.

[0007] Further optionally, the support assembly includes a plurality of U-shaped brackets fixed on the annular bracket, a rotating shaft is provided at the lower portion of the corresponding U-shaped bracket and a slider is slidably connected to the upper portion of the U-shaped bracket, sliding rods are provided on the left and right sides of the slider respectively, a prying rod is movably connected between the sliding rod and the rotating shaft, and an electric push rod is provided on one side of the slider and is connected and fixed to its telescopic rod.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0017] like Figure 1 , 3 As shown, an insulated pipe threading device includes an outer protective pipe placement rack 1 and a steel pipe conveyor 2. An annular bracket 6 is arranged at the feed port of the outer protective pipe placement rack 1, and a plurality of support components for expanding the port of the outer protective pipe 3 are arranged in an annular shape on the outer side of the annular bracket 6.

[0018] like Figure 1 , 2 As shown in Figure 3, the support assembly includes a plurality of U-shaped brackets 7 fixed on the annular bracket 6, a rotating shaft 15 is provided at the lower portion of the corresponding U-shaped bracket 7, and a slider 8 is slidably connected to the upper portion of the U-shaped bracket 7, a sliding rod 11 is provided on the left and right sides of the slider 8, a prying rod 10 is movably connected between the sliding rod 11 and the rotating shaft 15, and an electric push rod 9 is provided on one side of the slider 8 and is connected and fixed to its telescopic rod.

[0019] like Figure 2 As shown, a groove 12 for the sliding block 8 to slide is formed on the upper portion of the U-shaped bracket 7 , and first sliding grooves 13 for the sliding bar 11 to slide are formed on both sides of the groove 12 .

[0020] like Figure 1 , 2As shown in FIG. 3 , one end of the prying rod 10 is hingedly connected to the rotating shaft 15 , and the other end is provided with a second sliding groove 14 and is slidably connected to the sliding rod 11 .

[0021] like Figure 1 , 2 As shown in 3, the electric push rod 9 is connected and fixed to the annular bracket 6 through a bracket.

[0022] The implementation principle of the insulation pipe threading device in the embodiment of the present application is:

[0023] Before threading the pipe, first place the outer protective pipe 3 and the steel pipe 4 on the corresponding outer protective pipe placement rack 1 and the steel pipe conveyor 2, and then tie the support block 5 evenly on the steel pipe 4 (the tied support block 5 can pass through the interval gap between the corresponding bracing components) to prevent the steel pipe 4 from being eccentric after passing through the outer protective pipe 3. When placing the outer protective pipe 3, the end of the outer protective pipe 3 needs to be closely fitted with the inclined prying rod 10, and after close fitting, prepare for the pipe threading operation;

[0024] When threading the pipe, start the steel pipe conveyor 2, which will slowly and evenly convey the steel pipe 4 to the inside of the outer protective pipe 3. While conveying the outer protective pipe 3, start all the electric push rods 9. After all the electric push rods 9 are started, the telescopic rods will be retracted synchronously. When the telescopic rods are retracted, the slider 8 will be driven to move backward. When the slider 8 moves backward, the prying rod 10 will be pulled up. All the pulled up prying rods 10 will expand outward (the maximum outward expansion distance is 5-15mm greater than the diameter of the outer protective pipe 3). In the process of outward expansion, the port of the outer protective pipe 3 will be opened to ensure that the steel pipe 4 with the support block 5 tied thereto can smoothly enter the inner part of the outer protective pipe.

[0025] After all the steel pipes 4 have entered the outer protective tube 3, the electric push rod 9 is started to extend the telescopic rod synchronously, so the prying rod 10 will retract inward, and the outer protective tube 3 with the steel pipe 4 is removed, thereby completing the production of an insulation tube. The rest of the tubes are threaded according to the above steps. The entire tube threading process saves time and effort, better ensures the safety of life and property of operators, and greatly improves the production efficiency and economic benefits of the factory.

[0026] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
