Description

Technical Field

[0001] This utility model relates to the field of turning guide device technology, specifically to a cable bend seat that can reduce cable turning resistance. Background Technology

[0002] In coal mining, all electrical equipment relies on cables for power transmission, and the safe and reliable operation of these equipment is closely related to the use of cables. Ground-level cable warehouses typically store cables in reels, requiring manual dragging during loading and unloading. Dragging cables at bends increases resistance, making it difficult to move them with insufficient manpower. Each pull necessitates additional personnel to move the cables around bends, increasing labor costs and reducing work efficiency.

[0003] While using mechanical equipment to pull cables can solve the problems of high labor intensity and low construction efficiency in cable transportation at bends, most bends in coal mine roadways are right-angle protrusions, which can easily cause wear and tear on the cable sheath during the pulling process, damaging the cable's protective layer. Existing technologies also use auxiliary structures such as guide shafts to guide cables, but these structures are usually placed directly at the corner. During cable pulling, displacement or changes in angle can easily occur, causing the cable to re-contact with the corner and rub against it. Utility Model Content

[0004] To address the technical problem that when using existing auxiliary guiding structures such as guide shafts to pull cables, the auxiliary guiding structures are prone to displacement or angle changes, causing the cable to re-contact with the corner and rub against it, this utility model provides a cable bend seat that can reduce cable bending resistance. It is suitable for right-angle protruding corners in coal mine roadways, such as rectangular support columns, and can reduce cable dragging resistance and protect the cable sheath.

[0005] The technical solution of this utility model is as follows:

[0006] A cable bend holder that reduces cable bending resistance includes a base plate with a right-angle notch. A bonding plate is located on each side of the right-angle notch, and several suction cups are fixedly connected to the bonding plate near the right-angle notch. Two vertical mounting plates and a cantilever frame are fixedly connected to the base plate. The two mounting plates are positioned opposite each other, and a horizontal roller is rotatably connected between them. The cantilever frame includes a vertical plate and a top plate. The end of the top plate near the right-angle notch is fixedly connected to the top of the vertical plate, and a baffle is hinged to the end of the top plate away from the right-angle notch. A vertical roller is rotatably connected between the base plate and the top plate.

[0007] Furthermore, a limit plate is also provided at the end of the top plate that is hinged to the baffle, the limit plate being used to restrict the baffle from rotating outward.

[0008] Furthermore, an anti-slip strip is provided on the side of the bonding plate near the right-angle notch. Preferably, the anti-slip strip is spaced apart from the suction cup.

[0009] Furthermore, the base plate has a through hole, and the top edge of the through hole is integrally formed with a threaded sleeve. The threaded sleeve is connected to a fixing screw. Rotating the fixing screw causes it to move down and insert into the soil surface, which can reinforce the base plate and further prevent the base plate from shifting due to friction when the cable is pulled. When used on a cement floor, rotating the fixing screw in the opposite direction will retract the bottom end of the fixing screw into the through hole or the threaded sleeve, which can prevent the bottom end of the fixing screw from being damaged and thus reducing the soil breaking ability.

[0010] Furthermore, the bottom end of the fixing screw is provided with a cone, which makes it easier to insert into the muddy ground.

[0011] Furthermore, a rotating rudder is provided at the top of the fixed screw.

[0012] The beneficial effects of this utility model are as follows:

[0013] The cable bend holder provided by this utility model can avoid direct contact between the cable and the corner, effectively preventing damage to the cable protective layer caused by friction between the cable and the corner during the pulling process. The right-angle notch, suction cup and other structures make the cable bend holder fit more firmly with the external corner, reducing the probability of the base plate being displaced when the cable is pulled, and always keeping the cable bend holder at the corner, preventing the cable from re-contacting and rubbing against the corner after the cable bend holder shifts.

[0014] In this invention, when the cable is pulled, the vertical roller and the horizontal roller can convert sliding friction into rolling friction, which greatly reduces the friction force on the cable, thereby reducing the force required for the worker to pull it and reducing the worker's labor intensity.

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] Example 1

[0023] like Figures 1 to 4 As shown, a cable bend holder that can reduce cable bending resistance includes a base plate 1. The base plate 1 has a right-angle notch. A bonding plate 8 is provided on each side of the right-angle notch. Several suction cups 9 are fixedly connected to the side of the bonding plate 8 near the right-angle notch. The suction cups 9 are arranged in a matrix. An anti-slip strip 10 fixedly connected to the bonding plate 8 is provided between every two rows of suction cups 9.

[0024] Two vertical mounting plates 2 and a cantilever 3 are fixedly connected to one side of the base plate 1 near the right-angle notch. The two mounting plates 2 are arranged opposite each other, and a horizontal roller 4 is rotatably connected between the two mounting plates 2.

[0025] The cantilever frame 3 includes a vertical plate and a top plate. The end of the top plate near the right-angle notch is fixedly connected to the top of the vertical plate. The end of the top plate away from the right-angle notch is hinged to a baffle 6. The end of the top plate hinged to the baffle 6 is also provided with an integrally formed limiting plate 7. A vertical roller 5 is rotatably connected between the bottom plate 1 and the top plate. The vertical roller 5 is located between the vertical plate and the baffle 6, and the vertical roller 5 is adjacent to the horizontal roller 4.

[0026] The base plate 1 is also provided with through holes, preferably three through holes. Each through hole has a threaded sleeve 11 integrally formed on the top edge. The threaded sleeve 11 is internally threaded with a fixing screw 12. The bottom end of the fixing screw 12 is provided with a cone head, and the top end of the fixing screw 12 is provided with a rotating rudder 13.

[0027] When using this invention, align the right-angle notch of the base plate 1 with the bend. The suction cup 9 and anti-slip strip 10 ensure a more stable fit between the cable bend seat and the bend, preventing displacement of the base plate 1 when the cable is pulled, thus preventing the cable from being separated from the bend. When used on muddy ground, rotate the rudder 13 to rotate and lower the fixing screw 12, thereby inserting the cone into the ground to reinforce the base plate 1 and further prevent displacement of the base plate 1 due to friction when the cable is pulled. If used on concrete or other surfaces where insertion is not possible, reverse the rudder 13 to retract the cone of the fixing screw 12 into the through hole or threaded sleeve 11, preventing damage to the cone and a decrease in soil-breaking ability.

[0028] The cable is routed around the outside of baffle 6 (i.e., the side of baffle 6 away from vertical roller 5). When the cable is pulled, it tightens towards the side where baffle 6 is located. Baffle 6 rotates inward about the hinge point between its top and the top plate, allowing the cable to enter between baffle 6 and vertical roller 5. As the cable is pulled, it comes into contact with vertical roller 5 and rests on horizontal roller 4. Vertical roller 5 and horizontal roller 4 can convert sliding friction into rolling friction, greatly reducing the friction force on the cable, thereby reducing the force required for the worker to pull and reducing the worker's labor intensity.

[0029] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
