Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cutting device for a steam pipeline. Background Art

[0002] Steam pipes have good mechanical properties and thermal insulation properties. Under normal circumstances, they can withstand high temperatures of 120°C. Through modification or combination with other insulation materials, they can withstand high temperatures of 180°C. They are suitable for insulation projects of various cold and hot water high and low temperature pipes.

[0003] In order to meet the installation requirements, when installing steam pipes, workers are often required to cut the surface, such as dividing the pipe into two, or opening the pipe surface. In this process, a cutting knife is usually used for cutting or opening. However, the existing cutting knives have certain disadvantages in actual use, especially when the cutting tool is idle, the blade exposed to the air can easily scratch the workers. If such cutting tools are carried to the work site, the workers also need to carry many tools. If the various tools are stored together, the blade will not only scratch the surface of the tool, but the tool will also cause damage to the blade, which will affect the subsequent cutting effect.

[0004] To this end, we propose a steam pipe cutting device that can wrap the cutter head. Utility Model Content

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figure 1 to Figure 4 , which is the first embodiment of the utility model, provides a cutting device for a steam pipe, which opens or closes the cutting member 102 by controlling the movement of the closing member 201.

[0027] Specifically, the supporting component 100 includes a back plate 101 and a cutting piece 102 arranged on the outer wall of the back plate 101; and, the protecting component 200 includes a closing piece 201 movable on the outer wall of the back plate 101; and, the clamping component 300 includes a fixing plate 301 rotatably arranged on the outer wall of the back plate 101, a connecting plate 302 integrally formed on one end surface of the fixing plate 301, and a fixing channel 301a opened on the other end surface of the fixing plate 301 and used for clamping the steam pipe.

[0028] The back plate 101 is used to support all components contained in the device, the cutting member 102 is used to cut the pipe, and the clamping assembly 300 is used to fix the pipe when it is cut.

[0029] It should be noted that from Figure 4 It can be seen that the cross section of the fixing channel 301a is three quarters of the pipe cross section, and the pipe is fixed by clamping. In the initial state, the two fixing channels 301a are not on the same axis, and the fixing plate 301 is in a vertical state.

[0030] In summary, when cutting the pipeline, the two connecting plates 302 are controlled to rotate until the two fixed plates 301 remain horizontal and stop rotating. At this time, the two fixed channels 301a are in the same axial direction, and this action will trigger the closure 201 to move, so that the cutting piece 102 opens and the pipeline can be cut.

[0031] After the cutting operation is completed, the two sealing members 201 will be close to each other to protect the cutting member 102 and prevent the cutting blade 102a from being exposed to the air.

[0032] Example 2

[0033] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that this embodiment provides a movement trajectory of a closure 201 so that it will not affect the cutting operation as much as possible when it is opened.

[0034] Specifically, a connection groove K is formed on the outer wall of the back plate 101, and the connection groove K includes a transverse groove K-1 and an inclined groove K-2 connected to the transverse groove K-1. Figure 2 It can be seen that the transverse groove K-1 is horizontal, while the inclined groove K-2 is inclined.

[0035] The closing member 201 includes a first push plate 201a and a second push plate 201b hinged to one end of the first push plate 201a, and the outer walls of the first push plate 201a and the second push plate 201b are both slidably connected to the connection groove K. When the first push plate 201a enters the transverse groove K-1, the closing member 201 is integrated in an inclined state, and the cutting blade 102a is exposed to the air at this time, and when the second push plate 201b gradually approaches the inclined groove K-2, the first push plate 201a will enter the inclined groove K-2, the first push plate 201a will rotate, and the two first push plates 201a will also be closer due to their respective rotations, thereby protecting the cutting member 102.

[0036] A transmission plate 202 is integrally formed on the end surface of the second push plate 201b, and a first transmission channel 202a is penetrated through the outer wall of the transmission plate 202. A first rotating column 202a-1 is rotatably arranged in the first transmission channel 202a, and one end of the first rotating column 202a-1 is connected to the connecting plate 302.

[0037] In summary, when the worker is cutting, the worker should press the arc surfaces of the two connecting plates 302 relatively to make the connecting plates 302 rotate, as described in the first embodiment, so that the fixing plate 301 tends to be horizontal. In this process, the first rotating column 202a-1 will rotate in the first transmission channel 202a, driving the closing member 201 to move in the connecting groove K, and the two closing members 201 will move away from each other to open the cutting member 102. When the worker inserts the pipe into the fixing channel 301a, the state of the closing member 201 will be fixed.

[0038] Similarly, the rotation of the fixing plate 301 will also be fixed, and at this time, the staff can control the cutting member 102 to perform cutting operations on the surface of the pipeline.

[0039] It should be noted that if the pipe is divided into two parts instead of making an opening cut on the pipe surface, in order to ensure the cutting effect, it is best for the staff to lightly support the pipe to ensure the cutting effect.

[0040] Example 3

[0041] Reference Figure 1 to Figure 4 , which is the third embodiment of the utility model, is based on the previous embodiment, but differs in that a method for resetting the connecting plate 302 after rotation is also provided.

[0042] The reset assembly 400 is also included, including a reset plate 401 movably arranged outside the back plate 101, a second transmission channel 401a penetrating through the outer wall of the reset plate 401, and a second rotating column 402 rotatably arranged in the second transmission channel 401a, and one end of the second rotating column 402 is connected to the connecting plate 302. The second rotating column 402 cooperates with the second transmission channel 401a and other components, so that when the connecting plate 302 rotates, the reset plate 401 will move vertically downward.

[0043] The reset assembly 400 further includes an L-shaped plate 401b-1 screwed to the outer wall of the back plate 101, and the outer wall of the L-shaped plate 401b-1 is movably connected to the outer wall opening of the back plate 101, and the outer wall of the L-shaped plate 401b-1 is also sleeved with an elastic member 401b-2. The elastic member 401b-2 is a compression spring, and one end of the elastic member 401b-2 is connected to the reset plate 401. When the reset plate 401 moves vertically downward, the elastic member 401b-2 will be deformed so that the reset plate 401 has a reset effect.

[0044] The outer wall of the back plate 101 is provided with a back plate slot 101a which can be slidably connected with the reset plate 401, and both sides of the outer wall of the back plate 101 are penetrated with hand buckle slots 101b. Among them, the back plate slot 101a will provide a path for the reset plate 401 to move in the vertical direction.

[0045] The outer wall of the connecting plate 302 is penetrated with an anti-skid channel 302a, wherein the anti-skid channel 302a can facilitate the staff to rotate the connecting plate 302.

[0046] The cutting member 102 includes a cutting blade 102a screwed thereto, a bracket 102a-1 for supporting the cutting blade 102a, a platform 102b disposed outside the back plate 101, and an adjustment channel 102b-1 opened on the end surface of the platform 102b.

[0047] The inner wall of the adjustment channel 102b-1 is slidably connected to the bracket 102a-1, and the outer wall of the bracket 102a-1 is provided with a handle 102c. The cutting member 102 can be slightly displaced to ensure that the cutting depth requirement is met, and when controlling the displacement of the cutting blade 102a, it can be controlled by the handle 102c. The bracket 102a-1 is used to support the rotation of the cutting blade 102a, and the bracket 102a-1 is also equipped with a gear box and a motor that provides the cutting blade 102a with rotational power. The prior art has been fully documented and will not be described in detail here.
