Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, and in particular relates to a horizontal cable laying device. Background Technology

[0002] As the mine develops, aging cables need to be replaced continuously, requiring the investment of a large number of new cables. Upon arrival, the new cables are coiled on large cable reels. Before being deployed into the mine, they are laid out and then loaded onto specialized cable trucks for transport.

[0003] Before laying new cables, a crane is needed to lift the cable reel vertically and suspend it in the air, about 200mm above the ground. Five to six people surround the cable reel and slowly rotate it to pull the cable out of the reel and place it on the ground. Then it is loaded onto a special cable cart.

[0004] New cables are generally around 500m long, and the cable reels are huge (some are about 3 meters in diameter). When the cable is suspended in the air and pulled, it will sway slightly. Sometimes, because the cable is thick, it is difficult to pull it out, and the force is not uniform. The cable reel will swing more, which can easily injure people and also pose a risk of falling. This makes the cable laying labor-intensive, poses a high safety threat, and the safety of employees cannot be effectively guaranteed.

[0005] Especially when laying cables with large diameters, a lot of manpower is often required to assist in the cable laying. Not only is the cable laying operation often hindered due to insufficient manpower, but the above-mentioned cable laying methods also have a very high risk factor.

[0006] In existing technologies, cables are laid out by placing them on a rotating turntable. However, current turntables are only connected to the base by a single rotating shaft at their center. During the laying process, the cable reel needs to be hoisted onto the turntable using equipment such as a crane. It is difficult to ensure that the center of the cable reel and the center of the turntable are aligned during hoisting (i.e., the center of gravity of the cable reel often deviates from the center of the turntable due to inaccurate hoisting). This results in a very high risk during the cable laying process. Because the heavy cable's center is off-center from the rotation center, the rotating shaft is subjected to misalignment forces, making it extremely prone to breakage.

[0007] Meanwhile, during the cable laying process, the rotational stability of the turntable is not high due to the offset force, making it prone to shaking and creating a potential accident hazard of cable tipping over.

[0008] Therefore, using a cable laying device that is safe, labor-saving, flexible, and requires less manpower for cable laying operations not only significantly increases the safety factor of the operation, but more importantly, it can greatly improve the efficiency of cable laying and prevent accidents from occurring during the cable laying process. Utility Model Content

[0009] Based on the above background, the purpose of this utility model is to provide a horizontal cable laying device.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A horizontal cable unwinding device includes a cable unwinding mechanism, which includes a lower fixed base and a plurality of circumferentially distributed running wheel structures mounted on the top of the lower fixed base.

[0012] It also includes a rotating disk that supports the cable, which is supported on the running wheel structure;

[0013] A stabilizing rotation structure is assembled and connected between the lower fixed base and the rotary disk. During the rotation and unwinding process of the rotary disk load cable, the stabilizing rotation structure is used to increase the stability of the rotary disk rotating and unwinding the cable.

[0014] The stabilizing rotation structure includes a fixed rotating shaft fixedly installed at the top of the lower fixed base. The rotating disk has a mounting hole, and the stabilizing rotation structure is installed in the mounting hole. The stabilizing rotation structure includes several bearings rotatably connected to the fixed rotating shaft. The bearings are fixedly mounted with brackets. An annular mounting bracket that cooperates with the bracket is fixedly installed in the mounting hole. The bracket is fixedly mounted on the annular mounting bracket.

[0015] Preferably, the bottom of the rotating disk is fixedly connected to a track structure that cooperates with the running wheel structure, and the running wheel structure is limited to rolling within the track structure.

[0016] Preferably, the runway structure includes an outer runway ring welded and fixed to the bottom of the rotating disk, and an inner runway ring concentrically arranged inside the outer runway ring, the inner runway ring being welded to the bottom of the rotating disk;

[0017] The outer runway ring and the inner runway ring form a ring-shaped runway structure.

[0018] Preferably, the running wheel structure includes a running wheel, and an inner channel steel bracket and an outer channel steel bracket are rotatably connected to both ends of the running wheel, and the inner channel steel bracket and the outer channel steel bracket are fixedly connected to the top of the lower fixed base.

[0019] Preferably, both the inner channel steel support and the outer channel steel support include a U-shaped channel steel section;

[0020] Triangular ribs are welded to the side walls on both sides of the U-shaped channel steel section, and the triangular ribs are welded and fixed to the top of the lower fixed base.

[0021] Preferably, the running wheel includes a wheel body, and rolling flanges with annular structures are welded to both sides of the wheel body, and the rolling flanges roll within the track structure.

[0022] Preferably, the two ends of the wheel body are respectively welded with a rotating shaft, and the inner channel steel bracket and the outer channel steel bracket are respectively equipped with bearings that rotatably connect to the rotating shaft.

[0023] Preferably, the cross-sectional shape of the bracket is annular, and the bracket is fastened to the annular mounting bracket by a plurality of countersunk screws.

[0024] Preferably, a base support bracket is welded and fixed to the bottom of the fixed rotating shaft;

[0025] The base bracket is welded and fixed to the top center of the fixed base.

[0026] This utility model has the following beneficial effects:

[0027] 1. This utility model, through the design of a stabilizing rotating structure in conjunction with a running wheel structure, ensures that the cable reel can still be laid out in a stable and safe manner during the cable laying process, supported by the running wheel structure and under the fixed rotational action of the stabilizing rotating structure.

[0028] 2. A bracket is fixedly installed via the bearing. By welding a ring-shaped bracket to the outer ring of the bearing, which cooperates with the ring-shaped mounting bracket inside the mounting hole on the rotating disk, the installation stability of the bearing is increased, and the structural stability of the bearing limiting and fixing the rotating disk is improved, thereby effectively avoiding the technical defects of the rotating disk shaking and instability.

[0029] 3. The running wheel structure limits its rolling motion within the runway structure. The runway structure further complements the aforementioned stabilizing rotation structure, further preventing the rotating disc from wobbling during cable unwinding. This is because the running wheel structure, acting as a support structure, limits its rolling motion within the runway structure. This limiting state prevents the rotating disc from derailing and further avoids wobbling, increasing the stability and safety of cable unwinding.

[0030] 4. A base support bracket is welded to the bottom of the fixed shaft; the base support bracket is welded to the fixed base in a reinforced manner, which further increases the structural stability of the fixed shaft and avoids the risk of accidental breakage or deformation of the fixed shaft causing imbalance in cable laying.

[0031] 5. The wheel body is a long cylindrical structure. Therefore, the rolling flanges are fixed on the inner and outer sides of the wheel body. The span between the rolling flanges is large. During the rotation of the support, the rolling flanges on the inner and outer sides of the wheel body, which are distributed around the circumference, form a double-layered support rolling unit. Because the span between the inner and outer double-layered rolling units is large, the support span for the rotating disk is large and the support stability is high. Therefore, the support rolling structure designed with the long cylindrical structure of the wheel body has very high stability. Attached Figure Description

[0045] Example 1

[0046] like Figure 1-8 As shown, a horizontal cable unwinding device includes a cable unwinding mechanism 2, which includes a lower fixed base 21 (the lower fixed base 21 is disc-shaped). Several circumferentially distributed running wheel structures 23 are installed on the top of the lower fixed base 21. Specifically, there are eight running wheels distributed in a circumferential array.

[0047] It also includes a rotating disc 22 that supports the cable, which is supported on the running wheel structure 23. During the cable laying process, the cable reel is lowered onto the rotating disc 22 by rotating the crane.

[0048] A stabilizing rotation structure is assembled and connected between the lower fixed base 21 and the rotating disk 22. The stabilizing rotation structure ensures that even if the center of gravity of the cable reel 1 is misaligned with the center of the rotating disk 22 (i.e. the cable reel 1 is not accurately lowered, in actual operation, since the heavy cable reel 1 is lifted by a crane, it is impossible to guarantee that the center of gravity of the cable reel 1 is exactly at the center of the rotating disk 22).

[0049] Therefore, this utility model, by designing a stabilizing rotation structure in conjunction with the running wheel structure 23, achieves that, under the support of the running wheel structure 23 and the fixed rotation action of the stabilizing rotation structure, the cable reel 1 can still be laid out in a stable and safe manner during the cable laying process.

[0050] Specifically, the stabilizing rotation structure includes a fixed rotating shaft 24 fixedly installed at the top of the lower fixed base 21. Meanwhile, the rotating disk 22 has a mounting hole, in which the stabilizing rotation structure 25 is installed. The stabilizing rotation structure 25 includes a pair of bearings 252 that are spaced apart vertically and rotatably connected to the fixed rotating shaft 24.

[0051] By fixing the bearing 252 to the rotating disk 22 in a detachable and fixed manner, the bearing 252 serves as both a rotating connection structure and a limiting and fixing structure during rotation. Therefore, to increase the stability of the bearing 252 fixedly mounted on the rotating disk 22, a bracket 251 is fixedly mounted on the bearing 252. Specifically, the bearing 252 is a rolling bearing 252 disclosed in the prior art. By welding a ring-shaped bracket 251 to the outer ring of the rolling bearing 252, the installation stability of the bearing 252 is increased, and the structural stability of the bearing 252 limiting and fixing the rotating disk 22 is improved.

[0052] Therefore, a ring-shaped mounting bracket 253 (fixed by welding) that mates with the bracket 251 is fixedly installed in the mounting hole, and the bracket 251 is fixedly installed on the ring-shaped mounting bracket 253. Specifically, the bracket 251 has several circumferentially distributed threaded holes, and the ring-shaped mounting bracket 253 has matching threaded holes. The bracket 251 is fixedly installed on the ring-shaped mounting bracket 253 by countersunk screws.

[0053] Therefore, under the action of a structure consisting of a pair of bearings 252, brackets 251, and annular mounting brackets 253 spaced apart vertically, the rotating disk 22 is fully limited in its rotation.

[0054] Meanwhile, in order to improve the structural stability of the fixed rotating shaft 24, a bottom support bracket is welded and fixed to the bottom of the fixed rotating shaft 24; in order to further increase the structural stability of the fixed rotating shaft 24, specifically, the bottom support bracket is welded and fixed to the top center position of the fixed base.

[0055] The base support bracket has the following shape: the base support bracket includes a fixed seat fixed at the lower end of the fixed rotating shaft 24. Several reinforcing ribs are welded to the bottom of the fixed seat. The top of the reinforcing ribs is welded to the bottom of the fixed seat. The bottom is welded to the fixed base. The side wall is welded to the side wall of the fixed rotating shaft 24. In this way, the structural stability of the fixed rotating shaft 24 is increased and the defect of the fixed rotating shaft 24 being broken is avoided.

[0056] Example 2

[0057] like Figure 1-8 As shown, in this embodiment, based on the structure of Embodiment 1, a track structure that cooperates with the running wheel structure 23 is fixedly connected to the bottom of the rotating disk 22. The running wheel structure 23 is limited to rolling within the track structure. The track structure further cooperates with the above-mentioned stabilizing rotation structure to further prevent the rotating disk 22 from shaking during the unwinding of the cable reel 1. This is because the running wheel structure 23, as a support structure, is limited to rolling within the track structure. In the limited state, while preventing the rotating disk 22 from derailing, it further prevents the rotating disk 22 from shaking, and increases the stability and safety of the cable unwinding process.

[0058] Specifically, the runway structure includes an outer runway ring 26 welded and fixed to the bottom of the rotating disk 22, and an inner runway ring 27 concentrically arranged inside the outer runway ring 26. The inner runway ring 27 is welded to the bottom of the rotating disk 22; the outer runway ring 26 and the inner runway ring 27 form a ring-shaped runway structure.

[0059] Example 3

[0060] like Figure 1-8 As shown, in this embodiment, based on the structure of embodiment 2, the running wheel structure 23 includes a running wheel, with an inner channel steel bracket and an outer channel steel bracket rotatably connected to both ends of the running wheel. The inner and outer channel steel brackets are fixedly connected to the top of the lower fixed base 21. Both the inner and outer channel steel brackets include a U-shaped channel steel portion 231.

[0061] Meanwhile, the inner channel steel support and the outer channel steel support, which serve as the support structure 251, bear the load of the cable reel 1. Therefore, in order to increase the structural stability, triangular rib plates 2311 are welded to the side walls on both sides of the above-mentioned U-shaped channel steel part 231, and the triangular rib plates 2311 are welded and fixed to the top of the lower fixed seat 21.

[0062] The running wheel has the following structural shape:

[0063] The running wheel includes a wheel body 232 (the wheel body 232 is a long cylindrical structure, so the rolling flanges 2321 are fixed on the inner and outer sides of the wheel body 232. The span between the rolling flanges 2321 is large. During the rotation, the rolling flanges 2321 on the inner and outer sides of the circumferentially distributed wheel body 232 form a double-layer support rolling unit. Since the span of the double-layer rolling unit is large, the support span for the rotating disk is large and the support stability is high. Therefore, the wheel body is designed with a long cylindrical structure). The two sides of the wheel body 232 are respectively welded with annular rolling flanges 2321. The rolling flanges 2321 roll within the track structure (the purpose of this method is to maintain stable support and roll within the track structure through a pair of spaced rolling flanges 2321. At the same time, because the contact area with the track structure is small, the resistance during rotation is small and the rotation is more flexible).

[0064] The wheel body 232 is welded to two ends with a rotating shaft, and the inner channel steel bracket and the outer channel steel bracket are respectively equipped with bearings 2312 that rotatably connect to the rotating shaft.

[0065] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
