Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically a roller support for cable conveying. Background Technology

[0002] In fields such as power engineering, mining, and industrial production lines, cable conveying requires roller supports for stable support and efficient transmission. Traditional cable conveying supports generally suffer from the following problems: First, the support structure is mostly a rigid connection, lacking elastic buffer design, making it difficult to adapt to changes in cable weight or undulating conveying paths, and easily causing damage to the support and cable due to impact loads; Second, the guiding mechanism lacks precision, and the support body is prone to tilting when rising and falling, causing uneven force on the roller assembly or cable jamming, affecting the stability of the conveying; Third, roller maintenance is inconvenient, and replacing the bolt-fixed axles requires tools, which is time-consuming and labor-intensive, and cannot meet the rapid maintenance needs of high-load scenarios; Fourth, the height adjustment function is limited, relying mostly on manual measurement and bolt tightening, resulting in low adjustment efficiency and poor locking reliability, making it difficult to meet the precise positioning requirements under complex working conditions. Utility Model Content

[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides a roller bracket for cable conveying, which can effectively solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A roller support for cable conveying includes a base and a floating support mechanism that can be raised and lowered on the base, a support body connected to the floating support mechanism, and at least one pair of roller sets. The roller sets are symmetrically installed on both sides of the support body for bearing and rolling the cable. The support body has a U-shaped frame structure.

[0006] The floating support mechanism includes an elastic buffer structure for providing upward elastic support force and a guide limiting structure for constraining the lifting path of the support body to be vertical. The elastic buffer structure is connected to the base and includes a connecting column and a helical spring. The helical spring is sleeved on the connecting column and its two ends abut against the base and the support body, respectively.

[0007] As a further description of the above technical solution, the guide limiting structure includes at least two guide posts fixedly disposed on the base and guide sleeves correspondingly disposed on the support body, wherein the guide sleeves are slidably sleeved on the guide posts.

[0014] The cable conveying roller bracket of this utility model has at least one of the following beneficial effects during use:

[0015] The elastic buffer structure dynamically adjusts the height of the support body using helical springs, absorbing impact loads during transport, reducing rigid impacts, extending the service life of equipment and cables, and adapting to complex working conditions. The guide and limit structure ensures the vertical lifting and lowering of the support body, avoiding uneven roller force and cable jamming caused by tilting, thus improving operational stability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figure 1-4 As shown, this utility model provides a roller bracket for cable conveying, including a base 1, a floating support mechanism 2 that is vertically mounted on the base 1, a bracket body 3 connected to the floating support mechanism 2, and at least one pair of roller sets 301. The roller sets 301 are symmetrically installed on both sides of the bracket body 3 for bearing and rolling the cable. The bracket body 3 has a U-shaped frame structure.

[0024] The cable is placed between the roller assemblies 301 on both sides of the support body 3, and the limiting channel 305 formed by the first roller 302 and the second roller 303 provides vertical support. The V-shaped grooves on the rim surfaces of the first roller 302 and the second roller 303 contact the outer surface of the cable, and the wedge-shaped structure of the grooves achieves radial limiting of the cable, preventing it from shifting left or right during transportation.

[0025] When the cable moves under traction, the first roller 302 and the second roller 303 of the roller assembly 301 rotate synchronously, converting the sliding friction between the cable and the rollers into rolling friction, which greatly reduces the transmission resistance. Since the roller assembly 301 is symmetrically installed on both sides of the U-shaped support body 3, it forms a stable support structure, ensuring that the cable's transmission path in the horizontal direction remains straight.

[0026] If the cable weight changes or there are height fluctuations in the transmission path, the support body 3 can be raised or lowered vertically through the floating support mechanism 2. At this time, the helical spring sleeved on the connecting column 205 is compressed or stretched by the pressure of the support body 3, providing an upward elastic support force, so that the support body 3 can be dynamically adjusted with the cable height, and at the same time, it absorbs the vibration and impact during the transmission process through elastic buffering.

[0027] The floating support mechanism 2 includes an elastic buffer structure 201 for providing upward elastic support force and a guide limiting structure 202 for constraining the lifting path of the support body 3 to be vertical. The elastic buffer structure 201 is connected to the base 1. The elastic buffer structure 201 includes a connecting column 205 and a helical spring. The helical spring is sleeved on the connecting column 205, and its two ends abut against the base 1 and the support body 3 respectively.

[0028] This embodiment absorbs the impact load during cable transmission (such as the inertial force at the moment of start-up and shutdown, and vibration caused by uneven road surface) by the elastic deformation of the helical spring, thereby reducing the rigid impact between the support body 3 and the base 1, extending the service life of the equipment, and reducing mechanical damage to the cable.

[0029] When there is no external force locking, the support body 3 can automatically adjust with the cable height to adapt to complex working conditions (such as crossing ditches, climbing slopes, etc.), without the need for frequent manual intervention, thus improving the intelligence level of the conveying system.

[0030] Furthermore, the guide limiting structure 202 includes at least two guide posts 204 fixedly mounted on the base 1 and guide sleeves 203 correspondingly mounted on the support body 3. The guide sleeves 203 are slidably fitted onto the guide posts 204. During the lifting and lowering process of the support body 3, the guide limiting structure 202 formed by the guide posts 204 and the guide sleeves 203 restricts its movement path to the vertical direction, avoiding uneven force on the roller assembly 301 or cable jamming due to tilting. This significantly improves the straightness of the lifting and lowering of the support body 3, avoids poor contact or jamming between the rollers and cables due to tilting, and ensures long-term stable operation of the mechanism.

[0031] Furthermore, the roller assembly 301 includes a first roller 302 and a second roller 303, which are spaced apart in the vertical direction and coaxially mounted on the same side of the support body 3. A limiting channel 305 for constraining cable displacement is formed between the first roller 302 and the second roller 303. The limiting channel 305 formed by the second roller 303, combined with a V-shaped groove design, forms a "clamping" support for the cable, effectively constraining the radial and axial displacement of the cable, and avoiding cable sheath wear or deviation from the track caused by shaking during transportation. It is especially suitable for long-distance, high-precision cable laying scenarios.

[0032] Furthermore, the rim surfaces of the first roller 302 and the second roller 303 are provided with V-shaped grooves 304. The U-shaped support body 3 and the symmetrical roller group 301 form a rigid frame, which improves the torsional rigidity of the structure, ensures that the rollers on both sides are subjected to uniform force, and reduces abnormal wear of the rollers caused by uneven loading.

[0033] Furthermore, it also includes a height locking device 102, which comprises multiple toothed grooves disposed on the side wall of the support body 3 and a latching member pivotally mounted on the base 1. The latching member has a locking position that engages with the toothed grooves to restrict lifting and lowering. When it is necessary to fix the height of the support body 3, the latching member is operated to engage with the toothed grooves on the side wall of the support body 3, entering the locking position to prevent the support body 3 from accidentally lifting or lowering due to vibration or other factors.

[0034] Furthermore, the base 1 is equipped with an anti-slip pad 101 at its bottom. The anti-slip pad 101 at the bottom of the base 1 increases the friction with the mounting surface, ensuring the entire support remains fixed in position during cable transport and preventing displacement of the base 1 due to reaction forces. The anti-slip pad 101 at the bottom of the base 1 is made of a high-friction coefficient material (such as rubber), which can maintain the support's fixed position even on smooth surfaces or in vibrating environments, preventing cable transport deviations caused by slippage of the base 1.

[0035] Furthermore, the axles of the first roller 302 and the second roller 303 are detachably mounted on the bracket body 3 via quick-release pins. The quick-release pin structure enables rapid assembly and disassembly of the roller assembly 301, allowing maintenance personnel to replace a single roller within 5 minutes. This saves 70% of maintenance time compared to traditional bolt connections, making it particularly suitable for high-load conveying scenarios requiring frequent maintenance.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
