Description

Technical Field

[0001] This utility model relates to the field of cable cutting and processing technology, specifically to a cable cutting device used in power construction. Background Technology

[0002] In the field of power construction, cable cutting and processing refers to the process of precisely cutting cables using professional tools and equipment according to the power system design requirements and actual site needs, and then processing the cut cable ends to meet technical standards such as electrical connection and insulation protection.

[0003] Currently, in power construction, the cutting and processing of cables requires the use of clamping blocks at one end of the cable to ensure the stability of the structure at that location, and then the cutting blade is used to cut the cable at the cut point. However, using clamping blocks on the surface of the cable can easily cause damage to the cable surface, affecting its subsequent use. Therefore, there is a need to provide a cable cutting device that can solve the above-mentioned drawbacks and improve the usage effect. Utility Model Content

[0006] The base has a cavity in the middle of its upper end;

[0007] A cutting mechanism, comprising a hydraulic cylinder located directly above the base, with a cutting blade fixedly connected to the lower part of the output end of the hydraulic cylinder;

[0008] The positioning mechanism includes a bracket threaded to one side of the upper end of the base. The bracket has a connector that is equidistantly connected to both sides. One electric push rod is sleeved in one connector on one side and another electric push rod is sleeved in one connector on the other side. The output ends of the electric push rods are fixedly connected to positioning posts. A set of positioning posts are in contact with the outer surface of the cable.

[0009] Furthermore, positioning blocks are fixedly connected to the lower parts of both sides of the bracket, and positioning bolts are threaded through the middle of the positioning blocks and extend into the base.

[0010] Furthermore, the cutting mechanism also includes a mounting bracket whose lower end is fixed to the lower parts of both sides of the base, and a positioning ring is fixedly connected to the lower part of the outer surface of the hydraulic cylinder, and the positioning ring has threaded holes extending to the top of the mounting bracket at equal intervals in the middle.

[0011] Furthermore, it also includes an auxiliary cutting mechanism, which includes a receiving plate located above the cavity, with an opening at the top center of the receiving plate and positioned relative to the cutting blade.

[0012] Furthermore, a movable spring is fixedly connected to the corner of the bottom end of the receiving plate, and the lower end of the movable spring is fixed to the corner of the bottom end of the cavity.

[0013] Furthermore, a support column is fixedly connected to the center of the bottom of the cavity, and a control switch is fixedly connected to the upper end of the support column, which is in contact with the bottom of the receiving plate and electrically connected to the hydraulic cylinder through a wire.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is a cable cutting device for power construction, comprising:

[0027] The base 11 has a cavity in the middle of its upper part;

[0028] The base 11 provides structural installation and a stable environment, while the cavity provides space for the mounting plate 31 and movement.

[0029] The cutting mechanism includes a hydraulic cylinder 22 located directly above the base 11, and a cutting blade 24 is fixedly connected to the lower part of the output end of the hydraulic cylinder 22.

[0030] The controlled hydraulic cylinder 22 acts on the cutting blade 24, which in turn acts on the cable to complete the cut at the required position.

[0031] The cutting mechanism also includes a mounting bracket 21 whose lower end is fixed to the lower parts of both sides of the base 11. A positioning ring 23 is fixedly connected to the lower part of the outer surface of the hydraulic cylinder 22, and the positioning ring 23 has threaded holes that extend to the top of the mounting bracket 21 at equal intervals in the middle.

[0032] By inserting and tightening bolts into the threaded hole, the positioning ring 23 can be installed and fixed, thereby installing and fixing the hydraulic cylinder 22 and the mounting bracket 21.

[0033] The positioning mechanism includes a bracket 41 threadedly connected to one side of the upper end of the base 11. The bracket 41 has a mating interface 45 equidistantly connected to both sides. An electric push rod 42 is sleeved in one mating interface 45 on one side, and an electric push rod 43 is sleeved in one mating interface 45 on the other side. The output ends of the electric push rod 42 and the electric push rod 43 are fixedly connected to positioning posts 44. A set of positioning posts 44 are in contact with the outer surface of the cable.

[0034] The bracket 41, in conjunction with the interface 45, satisfies the installation and fixation of the electric push rod 42 and the electric push rod 43. The controlled electric push rod 42 and the electric push rod 43 act on the positioning post 44. Through the contact friction between the surface of the positioning post 44 and the cable, the cable to be cut can be structurally defined. The opening of multiple interfaces 45 can meet the cutting and positioning requirements of cables of different specifications by changing the spacing between the positioning posts 44.

[0035] Positioning blocks 46 are fixedly connected to the lower parts of both sides of the bracket 41, and positioning bolts are connected through the middle of the positioning blocks 46 and threaded into the base 11.

[0036] The positioning bolts are used to install and fix the positioning block 46, and the fixed positioning block 46 then fixes the bracket 41.

[0037] Working principle: In the process of cutting cables at the required location during power construction, one end of the cable extends outward during unwinding, and the spacing between a set of positioning posts 44 is adjusted in advance according to the specifications of the cable to be used. At this time, the outward-extending end of the cable extends into the space between the set of positioning posts 44, and the structure is constrained by the contact friction between the positioning posts 44 and the cable surface. In the subsequent cutting process, the cable extending outward between the set of positioning posts 44 needs to be extended further to ensure that it does not detach during the cable pullback process.

[0038] This solution ensures cable positioning while being applicable to cables of different specifications without damaging the cable surface. It is convenient to use and meets the requirements. At the same time, the tension of the cable during cutting can be adjusted by pulling back, preventing deformation of the cable when it is cut under tight conditions, thus further improving the performance.

[0039] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0040] It also includes an auxiliary cutting mechanism, which includes a receiving plate 31 located above the cavity, with an opening 32 at the top center of the receiving plate 31 and positioned relative to the cutting blade 24.

[0041] A movable spring 33 is fixedly connected to the corner of the bottom end of the receiving plate 31, and the lower end of the movable spring 33 is fixed to the corner of the bottom end of the cavity.

[0042] The receiving plate 31 can receive the cable during the cutting process, while the opening 32 receives the cutting blade 24. With the help of the elastic force of the movable spring 33, the cable can be cut at the required position while avoiding damage to the cutting blade 24 caused by prolonged hard contact.

[0043] A support column 34 is fixedly connected to the center of the bottom of the cavity, and a control switch 35 is fixedly connected to the upper end of the support column 34, which is in contact with the bottom end of the receiving plate 31 and is electrically connected to the hydraulic cylinder 22 through a wire.

[0044] The support column 34 is fixed to the control switch 35, and the hydraulic cylinder 22 can be controlled to rise by means of the control switch 35.

[0045] The auxiliary cutting-off mechanism also includes a control switch 38 that is connected through one side of the middle of the mounting bracket 21 and a collar 36 that is fitted onto the outer surface of the output end of the hydraulic cylinder 22. A movable column 37 is fixedly connected to one side of the outer surface of the collar 36 and abuts against the control switch 38. The control switch 38 is electrically connected to the hydraulic cylinder 22 through a wire.

[0046] The collar 36 is installed and fixed to the movable column 37. The hydraulic cylinder 22 can be lowered by the mutual contact between the movable column 37 and the control switch 38.

[0047] Working principle: In the above-mentioned cable cutting process, after the cutting blade 24 acts on the cable, it first extends into the opening 32. The receiving plate 31, under force, is compressed by the movable spring 33. During the descent of the receiving plate 31, after the bottom end of the receiving plate 31 comes into contact with the control switch 35, the control switch 35 controls the hydraulic cylinder 22, causing it to change from a descending state to a rising state. As the hydraulic cylinder 22 gradually rises, the movable column 37, after contacting the control switch 38, changes the hydraulic cylinder 22 from a rising state to a descending state. This process is repeated to continuously cut the cable. During the cutting process, the cable needs to be manually pulled and unwound.

[0048] This solution eliminates the need for manual operation, mechanically moving the cutting blade 24 up and down, saving time and improving operational efficiency.

[0049] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
