Description

Technical Field

[0001] This utility model belongs to the field of cable slide rail brackets, specifically, this utility model relates to a cable slide rail bracket. Background Technology

[0002] Currently, the cable sliding supports of 4S hoist power supply mechanisms mostly use plastic slot-type supports. Under the traction of the drive motor, the cable slides on the support. Due to the use of sliding friction, the following prominent problems exist: 1. High frictional resistance: The cable slides directly in the plastic slot, resulting in high resistance. The cable is prone to jamming when sliding, which not only increases the load on the drive motor, but also causes continuous and severe physical wear on the cable sheath.

[0003] 2. Severe cable damage: Long-term, high-frequency wear and tear causes the cable insulation layer to break down rapidly, which not only shortens the service life of the cable itself, but also poses safety hazards such as leakage and short circuit.

[0004] 3. High maintenance frequency and high cost: Frequent replacement and maintenance work due to cable wear not only generates high material costs, but also causes production interruptions due to equipment downtime for maintenance, affecting overall operational efficiency.

[0005] Utility model patent CN218665070U, published on March 21, 2023, discloses a cable guide bracket for a gantry crane. It includes multiple uprights spaced apart along the length of the gantry crane track on its outer side; a cable guide groove connected and fixed to the top of the uprights; and a sliding assembly slidably mounted within the cable guide groove. The sliding assembly includes a driving component slidably mounted within the cable guide groove, two driven components slidably mounted within the cable guide groove, and two force transmission rods. The two driven components are located on either side of the driving component and are connected to the driving component via the two force transmission rods. Each driven component has a connector for mounting the gantry crane's electrical cable. However, this cable guide bracket for a gantry crane does not completely solve the aforementioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a cable guide bracket that reduces cable wear, lowers safety risks, and ensures normal production operations.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The cable slide rail bracket includes a track, a support is slidably connected to the track, the support includes a mounting plate, an adjusting bolt is provided on the mounting plate, and the adjusting bolt is connected to a rolling support structure.

[0008] The adjusting bolts are located at both ends of the mounting plate and are vertically arranged. The adjusting bolts are threaded with a fastening nut and an adjusting nut. A mounting seat is sleeved on the adjusting bolt between the fastening nut and the adjusting nut. The rolling support structure includes a support roller with a trumpet-shaped cross-section. The support roller includes a rotating shaft, the end of which passes through the mounting seat. The mounting seat rests on the adjusting nut.

[0009] The support frame is equipped with two movable wheels on its top sides. The movable wheels are arranged in pairs and are located within a track.

[0010] The bottom of the mounting plate has an arc-shaped groove above the support roller.

[0011] The mounting plate has a slotted hole through which the adjusting bolt passes, and the head of the adjusting bolt and the fastening nut press the mounting plate together. The end of the shaft is provided with a pin.

[0012] The bottom opening of the track is provided with limiting flanges on both sides.

[0013] This utility model has the following technical effects: 1. Fundamentally reduce friction: Transform the sliding friction between the cable and the bracket into rolling friction, significantly reducing the coefficient of friction and solving the wear problem at its source.

[0014] 2. Significantly extends cable life: The cable sheath is almost unworn, and its health and service life are improved several times over, directly reducing the cost of cable procurement and replacement.

[0015] 3. Improved Equipment Operating Efficiency and Stability: Smoother Operation: Reduced drag resistance makes the 4S crane run more smoothly and easily, lowering the operating load and energy consumption of the drive motor.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0019] like Figure 1 and Figure 2 As shown, the cable guide rail bracket includes a track 1, with a bracket 2 slidably connected to the track 1. The bracket 2 includes a mounting plate 3, on which adjusting bolts 4 are provided, and the adjusting bolts 4 are connected to a rolling support structure. Compared to traditional plastic slot-type 4S crane cable guide rail brackets, where the cable is constrained within the slot, directly contacting and sliding against the plastic inner wall, resulting in high friction, low cable protection, and frequent maintenance and replacement, this cable guide rail bracket uses bearing-supported rollers 5, enhancing the protection of the cable by the bracket 2, reducing cable failure rate, lowering maintenance costs, and improving the safety of 4S crane operation. Although the initial investment for this modification is higher than that of traditional brackets, the return on investment is shorter and the long-term comprehensive economic benefits are more significant due to savings in maintenance manpower and material costs, as well as reduced production losses caused by downtime.

[0020] like Figure 1As shown, adjusting bolts 4 are located at both ends of the mounting plate 3 and are vertically positioned. A fastening nut 6 and an adjusting nut 7 are threaded onto the adjusting bolts 4. A mounting seat 8 is fitted onto the adjusting bolts 4 between the fastening nut 6 and the adjusting nut 7. The rolling support structure includes a support roller 5 with a trumpet-shaped cross-section. The support roller 5 includes a rotating shaft 9, the end of which passes through the mounting seat 8, which rests on the adjusting nut 7. In this structure, the height of the support roller 5 can be adjusted by controlling the rotation of the adjusting nut 7. This allows the support roller 5 to be adjusted to a suitable opening size according to the cable size, ensuring smooth cable movement without jamming. The adjusting nut 7 is a wing-shaped nut for easy rotation by the operator. During installation and testing, the cable is smoothly placed on all the support rollers 5. Then, test runs are conducted under various conditions, including slow speed, fast speed, no-load, and heavy load. The smoothness of cable movement, the presence of abnormal noise, and whether the cable will detach from the support rollers 5 are observed. Based on the test results, the height of individual adjusting nuts 7 is fine-tuned to ensure smooth cable movement. The aforementioned support roller 5 is installed by inserting the rotating shaft 9 into the mounting base 8. The axial direction of the rotating shaft 9 is perpendicular to the axial direction of the adjusting bolt 4, and the two are offset on the mounting base 8. Therefore, when the support roller 5 needs maintenance after a certain period of use, it is only necessary to remove the pin 10 and take out the rotating shaft 9 for replacement, without disassembling other parts, which makes the maintenance operation more convenient.

[0021] The rotating shaft 9 and the supporting roller 5 are connected by bearings. Good coaxiality and levelness between the two are essential; otherwise, cable misalignment, wear on the bracket 2, or excessive load on individual supporting rollers 5 may lead to failure. The bearings are located inside the supporting rollers 5. Ideally, deep groove ball bearings with sealing caps and models ZZ or 2RS are selected. These bearings offer advantages such as high radial load capacity, low friction coefficient, and suitability for high-speed rotation. This ensures they can withstand harsh working conditions such as dust and oil contamination in the workshop, effectively preventing the intrusion of dust, metal powder, and moisture. This guarantees the bearings can operate smoothly and continuously even in harsh workshop environments, ensuring their long-term operational flexibility and lifespan.

[0022] like Figure 1 and Figure 2 As shown, the bracket 2 has two movable wheels 11 on its top sides. The movable wheels 11 are arranged in pairs and are located inside the track 1. The movable wheels 11 are used to move the bracket 2, and the multiple movable wheels 11 can maintain the balance of the bracket 2 under the weight of the cable.

[0023] like Figure 1 As shown, the bottom of the mounting plate 3, above the support roller 5, has an arc-shaped groove 14. The arc-shaped groove 14 further increases the cable accommodating space, reduces friction on the bottom area of ​​the mounting plate 3, and improves the smoothness of cable movement.

[0024] like Figure 1 As shown, the mounting plate 3 has a waist hole 13, through which the adjusting bolt 4 passes. The head of the adjusting bolt 4 and the fastening nut 6 press the mounting plate 3 together. In the above structure, the fastening nut 6 pressing the mounting plate 3 together stabilizes the vertical posture of the adjusting bolt 4 and ensures the stable installation of the support roller 5. The hole on the mounting plate 3 through which the adjusting bolt 4 passes is the waist hole 13, which makes it easy to change the position of the adjusting bolt 4. The appropriate model of support roller 5 can be selected and installed according to the outer diameter of the cable, thus improving the applicability.

[0025] like Figure 1 As shown, a pin 10 is provided at the end of the rotating shaft 9. The pin 10 is used to limit the rotation of the rotating shaft 9, ensuring that the support roller 5 is stably restricted between the two mounting seats 8. like Figure 1 As shown, the bottom opening of track 1 has limiting flanges 12 on both sides. Track 1 can be made of tubular profile. The bracket 2 can be installed directly from the end opening of track 1. The limiting flanges 12 are formed by bending at the bottom opening of track 1, which limit the movement of the casters 11 and simultaneously create two paths for the casters 11 on both sides of the bracket 2 to move. Anti-detachment grooves or limiting blocks can also be added to the end of track 1 to prevent the bracket 2 from falling off.

[0026] Working method: After removing all traditional plastic slotted brackets, install bracket 2 on track 1 at predetermined intervals, and place the cable smoothly on the support rollers 5, ensuring good contact between the cable and each support roller 5. When the 4S crane moves, the drive motor drives the cable to move, causing the support rollers 5 to rotate. The friction mode changes to rolling friction, and the cable moves smoothly without jamming.

[0027] This cable guide bracket has the following technical advantages: 1. Fundamentally reduce friction: Transform the sliding friction between the cable and the bracket into rolling friction, significantly reducing the coefficient of friction and solving the wear problem at its source.

[0028] 2. Significantly extends cable life: The cable sheath is almost unworn, and its health and service life are improved several times over, directly reducing the cost of cable procurement and replacement.

[0029] 3. Improved Equipment Operating Efficiency and Stability: Smoother Operation: Reduced drag resistance makes the 4S crane run more smoothly and easily, lowering the operating load and energy consumption of the drive motor. Reduced Downtime: Faults caused by cable wear and unplanned maintenance are virtually eliminated, significantly increasing equipment availability. Significant Safety Benefits: The risk of short circuits and leakage caused by cable sheath damage is completely eliminated, improving the safety level of the entire electrical system and ensuring the safety of personnel and equipment.
