Description

Technical Field

[0001] This utility model belongs to the field of cable stripping technology, and specifically relates to a simple device for stripping the PE layer of steel strands. Background Technology

[0002] Steel strand is a steel product made of multiple steel wires twisted together. It is commonly used in bridges, buildings, water conservancy, energy, and geotechnical engineering. Since the main material of steel strand is metal, metal is prone to corrosion and rust due to environmental problems during use, which seriously affects its service life. Therefore, a PE layer needs to be wrapped around it. PE is a common plastic material with excellent chemical corrosion resistance, electrical insulation, and mechanical strength. Therefore, the added PE layer can greatly extend the service life of steel strand and improve its overall performance.

[0003] However, the introduction of the PE layer also brought certain problems. When the steel strand is recycled, the outer PE layer needs to be removed, and only the inner metal wires need to be recycled. The traditional method of removal is to use a "chopping" motion to make an opening in the PE layer, and then manually remove the PE. The disadvantages of this method are that it is often difficult to control the force when opening the PE layer, which can easily damage the iron core of the steel strand and seriously affect the installation quality; moreover, the PE of the steel strand has strong adhesion, making the removal of the PE labor-intensive. In addition, the grease present during the removal process makes it slippery, and the steel strand is tough enough that it can easily injure the construction workers if not handled carefully.

[0004] Patent CN220122500U discloses a device for stripping PE from steel strands. The device includes a base, with a first fixed seat and a second fixed seat at each end of the top of the base. A dividing cylinder is located on the side of the first fixed seat near the second fixed seat. Multiple axially arranged dividing blades are arranged on the inner wall of the dividing cylinder. A pick blade, coaxially arranged with the dividing cylinder, is located on the side of the second fixed seat near the first fixed seat. A punch blade and a drive mechanism for reciprocating the punch blade are fitted around the pick blade. The steel strand is sequentially pulled through the dividing cylinder and the pick blades. The dividing blades divide the PE layer of the steel strand into several parts, and the bevel of the pick blades separates the divided PE layers outwards. Pulling the steel strand is stopped once the length of the steel strand with the PE layer removed meets the construction requirements. This device requires fixed installation of the base during use, thus its ease of use is low, and the installation location is easily affected by the environment. Furthermore, due to the strong adhesion of PE to the steel strand, dividing it into several parts increases the difficulty of stripping and adds to the stripping process. Utility Model Content

[0024] Example

[0025] like Figs. 1-2 As shown, a simple steel strand PE layer stripping device includes a stripping device slidably sleeved on the steel strand 100. The stripping device includes a cutting part 210, an adjusting and locking part 220, and an mounting part 230. The mounting part 230 is sleeved on the steel strand 100 and has a cutting groove 234. The cutting part 210 is rotatably mounted on the mounting part 230 through the adjusting and locking part 220. The cutting part 210 passes through the cutting groove 234 to cut the PE layer of the steel strand 100. The cutting depth of the cutting part 210 is fixed by the adjusting and locking part 220. The specific operation method is as follows: First, insert the steel strand 100 into the insertion end of the mounting part 230, rotate and adjust the cutting position of the cutting part 210, and lock it with the adjusting locking part 220 to ensure the stability (fixation) of the cutting depth. The operator holds the mounting part 230 and moves it along the axial direction of the steel strand 100. The cutting part 210 is used to cut open the PE layer of the steel strand 100. During the cutting process, the PE layer on the steel strand 100 can be separated from the internal metal wire at the same time, thus completing the stripping operation of the PE layer of the steel strand 100.

[0026] In some preferred embodiments, the mounting part 230 includes a straightening sleeve 231, a connecting plate 232, and a reinforcing rib 233. The connecting plate 232 is vertically mounted on the outer wall of the straightening sleeve 231. One end of the reinforcing rib 233 is connected to the straightening sleeve 231, and the other end is connected to the connecting plate 232. The straightening sleeve 231, the connecting plate 232, and the reinforcing rib 233 together form a stable triangular support structure. Therefore, the cutting groove 234 is located at the insertion point of the straightening sleeve 231 and close to the straightening tube. At the side where the sleeve 231 forms an angle with the connecting plate 232, the steel strand 100 is inserted through the insertion port of the straightening sleeve 231. It is worth mentioning that, in order to ensure the rigidity of the stripping device during the stripping process, and to ensure that it can provide support for the steel strand 100 during the cutting process, while also straightening the stripped section, the mounting part 230 is made of steel, and the inner diameter of the straightening sleeve 231 is larger than the diameter of the steel strand 100, ensuring that the steel strand 100 can be smoothly inserted into the straightening sleeve 231.

[0027] In some preferred embodiments, the adjusting locking part 220 includes a locking nut 221 and a connecting bolt 222, the cutting part 210 is rotatably mounted on the connecting plate 232 by the connecting bolt 222, and the locking nut 221 is threadedly connected to the connecting bolt 222.

[0028] In some preferred embodiments, it is worth mentioning that the cutting part 210 can be a common utility knife. In this design, the cutting part 210 is a utility knife. Therefore, the cutting part 210 includes a mounting sleeve 211, a cutting blade 212, a tail cap 213, and a push-blade button 214. The mounting sleeve 211 is rotatably mounted on the connecting plate 232 by the connecting bolt 222. A slide rail is provided through the mounting sleeve 211, and several slots are provided on opposite sides of the slide rail. The cutting blade 212 is mounted on the push-blade button 214. The cutting blade 212 is slidably disposed on the slide rail by the push-blade button 214. The push-blade button 214 is provided with an elastic locking key that matches the slots to allow... The push-blade button 214 can be inserted into the slot. A locking element is also slidably provided on the push-blade button 214. The locking element can prevent the elastic locking key from disengaging from the slot, ensuring that the length of the extended cutting blade 212 is maintained. The tail cap 213 is installed at the tail end of the mounting sleeve 211 to restrict the sliding out of the push-blade button 214. When it is necessary to readjust the length of the cutting blade 212 extending out of the mounting sleeve 211, or when it is necessary to retract the cutting blade 212 back into the mounting sleeve 211, it is only necessary to slide the locking element again to release the locking element from the obstruction of the elastic locking key, so that the elastic locking key can disengage from the slot, and the push-blade button 214 resumes sliding in the slide.

[0029] Next, the working principle and operation steps of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0030] First, adjust the extension length of the cutting blade 212 of the cutting part 210, and fix (hold) the extension length of the blade by locking. Then, insert the steel strand 100 into the insertion end of the straightening sleeve 231, rotate and adjust the cutting position of the cutting part 210 to ensure that the cutting blade 212 acts on the PE layer of the steel strand 100. Determine the cutting depth by observation, and lock it by the adjusting locking part 220 to ensure the stability (fixation) of the cutting depth. The operator holds the mounting part 230 (specifically, holds the angle formed between the straightening sleeve 231 and the connecting plate 232) and moves it along the axial direction of the steel strand 100. The cutting part 210 cuts open the PE layer of the steel strand 100. During the cutting process, the PE layer on the steel strand 100 can be separated from the internal metal wire at the same time, completing the stripping operation of the PE layer of the steel strand 100.

[0031] In summary, this utility model provides a simple steel strand PE layer stripping device. This stripping device is highly flexible in operation when stripping the PE layer of the steel strand. It does not require finding a position to fix it. After adjusting the cutting depth of the PE layer, you can hold the device and cut along the axial direction of the steel strand. The operation is very convenient and the cutting depth and cutting position can be flexibly adjusted.
