TECHNICAL FIELD
[0001] The utility model relates to mine and tunnel rock drilling and anchor rod equipment technical field especially relates to a cable guiding device. BACKGROUND
[0002] In the field of mine and tunnel rock drilling and anchor rod equipment, cable guiding devices play a crucial role. With the continuous expansion of mining and tunnel construction scale, the degree of automation and intelligence of equipment is increasingly required, and as the key component of equipment power and signal transmission, the stability and safety of cable laying and guiding directly affect the progress and quality of the entire project. In complex mine and tunnel environment, cables need to be frequently moved and bent, and also have to withstand various harsh working conditions such as humidity, dust, vibration, etc. Therefore, designing an efficient, reliable and durable cable guiding device has become a research hotspot in this field. Such a device not only can guide the cable to move along the predetermined path, but also can ensure that the cable is not damaged during movement, so as to ensure the normal operation and safe production of equipment.
[0003] At present, in the field of mine and tunnel rock drilling and anchor rod equipment, the existing cable guiding devices usually adopt relatively traditional mechanical structure and technical principle. The common structure is to realize the guiding of cable through a series of supports and pulleys. The support is generally welded by metal material, which plays the role of support and fixation. The pulley is installed on the support, and the cable moves around the pulley. Its technical principle mainly uses the rolling of pulley to reduce the friction between cable and support, so that the cable can move relatively smoothly. In some devices, springs or buffer devices are also used to absorb the impact force generated during the movement of cable, in order to protect the cable and equipment. In addition, in order to adapt to different working environment and cable specifications, some devices also have adjustable function, which adjusts the angle of support or the distance of pulley to meet different use requirements.
[0004] However, the existing cable guide device has a serious problem that when the cable passes through the guide device at an angle, the cable will generate serious friction with the guide bracket. In the traditional design, due to the fixed way of the drum shaft adopting threaded fixing, a larger space is needed to place the nut and other fasteners, which makes the gap at the intersection position of the longitudinal drum and the transverse drum cannot be further reduced. When the cable passes through these gaps at an angle, it is easy to scratch the corners of the guide bracket. In the harsh working environment of mines and tunnels, this scratch will intensify over time, causing the cable sheath to gradually wear. The wear of the cable sheath not only reduces the insulation performance of the cable, increases the risk of electric leakage and short circuit, but also affects the service life of the cable, increases the maintenance cost and downtime of the equipment, and in severe cases, even causes safety accidents, which brings great hidden dangers to the production of mines and tunnels. Therefore, a cable guide device is proposed to solve the above problems. Content of the utility model
[0005] In order to make up for the above shortcomings, the utility model provides a cable guide device, which aims at improving the problem of cable wear caused by friction between cable and guide bracket when making an angle in the prior art.

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the roller shaft fixing is changed from threaded to slotted pressure plate, which saves space, reduces the gap between the longitudinal and transverse rollers, and avoids the cable scraping the guide bracket when passing through the corner. The guide bracket is made of blank plate, which is simple to manufacture and the accuracy is easy to guarantee.

[0029] 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.
[0030] Reference Figure 1 - Figure 3 A cable guiding device includes a roller 3 made of high-strength, high-wear-resistant nylon material. This material not only has good flexibility, which can reduce damage to the cable sheath, but also maintains stable performance during long-term use. The outer surface of the roller 3 is finely polished and has a smooth cylindrical shape, which can provide stable rolling support for the cable and accurately guide the movement direction of the cable. The roller 3 is the main body of the device, which is used to provide rolling support for the cable and guide its movement direction. The fixing component is set on the outer wall of the roller 3 for placing and fixing the roller 3. The transmission component is set inside the roller 3 for driving the roller 3.
[0031] The transmission assembly includes a connecting shaft 6, the outer wall of which is located inside the drum 3. Snap rings 7 are provided on both sides of the connecting shaft 6, and bearings 8 are fixedly connected to both sides of the connecting shaft 6. The bearings 8 are high-precision rolling bearings, characterized by low friction, high speed, and long life. The outer wall of the bearing 8 is connected to the interior of the drum 3 via a transition fit, ensuring that the drum 3 rotates flexibly on the connecting shaft 6. This effectively reduces friction during drum 3 rotation, improving the transmission efficiency and stability of the device. The outer wall of the bearing 8 is fixedly connected to the interior of the drum 3. The fixing assembly includes a guide bracket 5, which is located on the outer wall of the drum 3. The guide bracket 5 is the main structure of the device, used to support and place other parts. A slot 4 is provided inside the guide bracket 5, and both ends of the connecting shaft 6 are slidably connected to the slot 4. A pressure plate 1 is provided on the outer wall of the guide bracket 5, used to press and fix the connecting shaft 6 within the slot 4 for stability. Bolts 2 are threaded inside the pressure plate 1, and their outer walls are threaded into the guide bracket 5. The pressure plate 1 and the guide bracket 5 are connected by bolts 2, which maintain a stable connection.
[0032] Specifically, in the guiding and transporting of mining cables, existing devices often experience cable wear. To solve this problem, the two ends of the connecting shaft 6 are placed inside the corresponding slots 4 on the guide bracket 5, thus placing the roller 3 inside the guide bracket 5. Next, the pressure plate 1 is placed on the outer wall of the guide bracket 5, and bolts 2 are threaded into the pressure plate 1 and the guide bracket 5 to achieve a tight connection, thereby firmly fixing the connecting shaft 6 in the slots 4. Then, the roller 3 can rotate freely through the bearing 8 on the connecting shaft 6. When the cable passes through the roller 3, the rotation of the roller 3 can effectively protect the cable. The improved guidance system avoids direct contact between the cable and the corner of the guide bracket 5, greatly reducing cable wear. The screw-on fixing has been replaced with a clamping groove 4 and pressure plate 1 fixing, saving space for nuts and fasteners. The gap between the longitudinal roller 3 and the transverse intersection is also reduced, preventing the cable from scraping the guide bracket 5 when passing diagonally through corners, thus preventing wear. This not only ensures the cable's guiding function but also improves the device's durability and reliability. Furthermore, the guide bracket 5 is a blank plate component, making manufacturing simpler and ensuring dimensional accuracy, thereby guaranteeing that the cable will not be worn during the guiding process.
[0033] Working principle: When guiding and transporting mining cables, the two ends of the connecting shaft 6 can be placed inside the corresponding slots 4, thereby placing the roller 3 inside the guide bracket 5. Then, the pressure plate 1 is placed on the outer wall of the guide bracket 5, and the bolts 2 are screwed into the pressure plate 1 and the guide bracket 5 to connect the two, so that the connecting shaft 6 is fixed inside the slot 4. Then, the roller 3 can be rotated through the bearing 8 to guide the cable, avoiding contact between the cable and the corner of the guide bracket 5, thereby reducing wear.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
