Description

Technical Field

[0001] The utility model relates to the field of cutting, in particular to a pipeline thermal insulation cotton cutting device. Background Art

[0002] Pipes are commonly used in daily life and can be used to transport water, gas, hot air, etc., such as water pipes, gas pipes and air conditioning pipes. Since the above pipes are exposed to the air when in use, in cold weather, the water pipes will freeze, which may cause the waterway to be blocked or even burst.

[0003] The copper tube of the air conditioner is wrapped with thermal insulation cotton to form an insulation layer, which can reduce the heat exchange with the outside world. Tee pipes are often used on the pipes to connect the pipe branches, such as T-shaped tees and Y-shaped tees. When wrapping the sponge on the pipe branch, since the pipe branch is connected to the main pipe, the connection point is wrapped with thermal insulation cotton. Due to the existence of the cylindrical surface on the outside of the pipe, if the thermal insulation cotton is directly wrapped at the connection point, the wrapping will be tight and the thermal insulation cotton on the branch cannot fit together with the main pipe. In order to ensure that the pipe branch and the main pipe can fit together tightly when wrapped, a cutting device for cutting the thermal insulation cotton is proposed. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] Please refer to Figure 1 This embodiment provides a pipe insulation cotton cutting device, comprising a cutting tube 1 and an inserting tube 3. The inner diameters of the cutting tube 1 and the inserting tube 3 are the same as the outer diameter of the insulation cotton. The inserting tube 3 has the same diameter as the cutting tube 1. One end of the inserting tube 3 is fixedly connected to the cutting tube 1. The inserting tube 3 is in an inclined state. Figure 1 As shown, the insertion tube 3 is communicated with the cutting tube 1. The insertion tube 3 is used to insert the heat preservation cotton of the water pipe (or oil pipe, gas pipe).

[0030] Also includes a drilling machine 8, such as Figure 1 and Figure 2 As shown, the drill is a handheld drill (or a handheld electric drill), and a cylindrical cutting tool 9 is fixedly installed at the output end of the drill 8. The cutting tool 9 is a hollow cylindrical tube structure, one end of the cutting tool 9 is fixedly connected to the output end of the drill 8, and the other end is provided with a blade. The diameter of the cutting tool 9 is the same as the inner diameter of the cutting tube 1.

[0031] When water pipes, oil pipes or gas pipes are in use, branch structures will be connected to the pipes. A common branch structure is to use a tee joint (or T-shaped joint) to realize the branching of the pipe. When wrapping the pipe, due to the existence of an arc-shaped surface at the pipe interface of the tee joint (or T-shaped joint), when the pipe is wrapped with thermal insulation cotton, it is not easy to wrap the branch of the tee joint (or T-shaped joint). Therefore, it is necessary to cut the thermal insulation cotton into an arc-shaped surface to adapt to the branch of the tee joint (or T-shaped joint).

[0032] When cutting the thermal insulation cotton, the thermal insulation cotton is inserted from the insertion tube 3 into the inner cavity of the cutting tube 1, and then the cutting tool 9 is inserted into the cutting tube from one end of the cutting tube 1, and the drill 8 is started, and the drill 8 rotates with the cutting tool 9 to achieve the cutting of the thermal insulation cotton. The angle between the insertion tube 3 and the cutting tube 1 is fixed. When cutting the thermal insulation cotton, the angle between the insertion tube 3 and the cutting tube 1 needs to be selected according to the structure of the tee. For example, when the structure of the tee is T-shaped, the insertion tube 3 and the cutting tube 1 can be set to a vertical state, and the arc surface produced by the cut thermal insulation cotton is perpendicular to the cutting tool 9, and the arc portion after cutting can match and fit with the T-shaped structure of the tee.

[0033] Example 2

[0034] When cutting thermal insulation cotton for different pipeline tees, due to the different angles between different tees, it is necessary to cut arc surfaces at different angles to fit different tees, and the above-mentioned insertion tube 3 is fixedly connected to the cutting tube 1, and cannot adapt to tees of different angles. When cutting different thermal insulation cotton, different insertion tubes and cutting tubes are required, which is inconvenient when cutting thermal insulation cotton. Therefore, in order to improve the adaptability to different tees, in this embodiment, the insertion tube 3 is rotatably connected to the cutting tube 1. The specific setting method is as follows:

[0035] The cutting tube 1 is provided with an arc-shaped opening 5 near the middle to ensure that Figure 2-Figure 8 As shown. Support plates 4 are fixedly installed at the edges of both sides of the arc-shaped opening 5, an axial hole is opened at the upper end of the support plate 4, and a rotating shaft is fixedly installed at the bottom of the insertion tube 3, the rotating shaft is inserted into the axial hole, and the rotating shaft can rotate in the axial hole. The insertion tube 3 can rotate around the rotating shaft from a horizontal state to a vertical state. When the insertion tube 3 is in the 0 degree state, it is in a horizontal position and is parallel to the cutting tube 1. The arc-shaped opening 5 needs to be set relatively large, and it is necessary to ensure that when the insertion tube 3 is tilted to 10 degrees, the thermal insulation cotton inserted into the insertion tube 3 can extend into the cutting tube 1.

[0036] An arc plate 2 is also fixedly mounted on the cutting tube 1, and the arc plate 2 is in the state of at least one quarter of a circle. Preferably, it is two-fifths of a circle. The rotating shaft of the insertion tube 3 coincides with the center of the arc plate 2. An arc groove is provided on the arc plate 2, and a fastening bolt 7 is fixedly mounted on the insertion tube 3. The end of the fastening bolt that does not contact the insertion tube 3 is located in the arc groove and extends out of the arc groove, and a fastening nut is rotatably mounted on the end of the fastening bolt that extends out. In the tightened state, a clamping force is formed between the fastening nut and the arc plate 2, and the insertion tube 3 is fastened to the arc plate, thereby fixing the position of the insertion tube 3.

[0037] The arc plate 2 is also provided with angle lines, and the interval between adjacent angle lines is 1 degree. There are also digital marks of 0 degrees, 5 degrees, 10 degrees, 15 degrees, etc., up to 90 degrees, and a digital mark is set every 5 degrees. When the insertion tube 3 is in a vertical state, Figure 8 As shown. A reference line parallel to the axis of the insertion tube 3 is provided on the side of the insertion tube 3, and the reference line passes through the axis of the rotating shaft. Figure 2 and Figure 4-8 As shown, when adjusting the angle of the insertion tube 3, the reference line takes the axis of the rotation shaft of the insertion tube 3 as the center of the circle and rotates with the insertion tube 3. No matter what position it rotates to, the reference line can coincide with the angle line, which makes it easier to position the angle of the insertion tube 3.

[0038] When determining the angle of the insertion tube 3, the degree of the insertion tube 3 is determined according to the angle between the three-way pipes. For example, when the branch angle of the three-way pipe is 30 degrees, loosen the fastening nut, rotate the insertion tube 3 so that the reference line is aligned with the 30-degree scale line, and then tighten the fastening nut to position the insertion tube 3, and then insert the thermal insulation cotton into the insertion tube 3. The thermal insulation cotton can be cut using a drill and a cutting tool 9. The arc surface angle cut out of the thermal insulation cotton is an arc surface angle of 30 degrees, which can fit the 30-degree branch angle of the three-way pipe, and the arc surface angle can be directly fitted on the 30-degree branch.

[0039] Since an arc-shaped opening is provided on the cutting tube, and the arc-shaped opening has no obstruction or limitation, the thermal insulation cotton can easily fall out of the arc-shaped opening or be pushed out when the sponge in the cutting tube 1 is cut. In order to prevent the thermal insulation cotton from being pushed out of the arc-shaped opening 5, a sliding tube 6 is provided on the cutting tube 1 along the side where the cutting tool moves forward. The sliding tube 6 is coaxially arranged with the cutting tube 1, and the inner diameter of the sliding tube 6 is the same as the outer diameter of the cutting tube 1. An axially distributed slide groove is provided on the cutting tube 1, and a fastening bolt is rotatably installed on the sliding tube 6. One end of the fastening bolt passes through the sliding tube 6 and extends into the slide groove. When the fastening bolt contains a fastening nut, the fastening bolt is pressed against the slide groove, and the sliding tube 6 is fastened to the cutting tube 1. When loosened, the fastening bolt is separated from the slide groove, and the sliding tube 6 can slide on the cutting tube 1.

[0040] When cutting the thermal insulation cotton, first determine the angle of the insertion tube 3, and then insert the thermal insulation cotton into the insertion tube 3. Figure 3 Then push the sliding tube 6 close to the thermal insulation cotton, and when the sliding tube 6 contacts the thermal insulation cotton, as shown in the dotted line. Figure 7 In the state shown by the dotted line, the sliding tube 6 can be fixed. When cutting the thermal insulation cotton, the cutting tool 9 is inserted into the cutting tube 1. The cutting tool 9 exerts a forward squeezing force on the thermal insulation cotton. The sliding tube 6 protects the thermal insulation cotton to prevent the thermal insulation cotton from being exposed from the arc opening 5, thereby ensuring the cutting of the thermal insulation cotton.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
