Description

Technical Field

[0001] The utility model relates to the technical field of mine equipment, in particular to a cable hanging device based on a single-track hoist track. Background Technique

[0002] With the continuous advancement of the informatization, standardization, and normalization of coal mine roadways, higher requirements are put forward for the layout of underground electrical circuits and pipelines. Especially during the continuous installation and removal of mining faces in the mine, it is necessary to reasonably arrange facilities such as power cables, monitoring cables, and signal cables in a limited space.

[0003] At present, most of the cable hanging devices in coal mines adopt traditional methods, that is, hooks are installed on the side walls of the roadway and fixed with bolts. Although this hanging method can meet the basic cable hanging requirements, there are some deficiencies in actual applications. For example, the installation and disassembly processes are relatively cumbersome, not only consuming time and labor, but also increasing the labor intensity of workers in a narrow space and even bringing potential safety hazards.

[0004] Therefore, how to provide a cable hanging device based on a single-track hoist track to simplify the installation and disassembly process, reduce the labor intensity of workers, improve work efficiency, and ensure the stable and reliable hanging of cables is a technical problem that needs to be solved by those skilled in the art at present. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cable hanging device based on a single-track hoist track, which solves the technical problems of the traditional installation method being relatively cumbersome, consuming time, and increasing the labor intensity of workers.

[0006] To achieve the above purpose, the utility model provides a cable hanging device based on a single-track hoist track. There are lifting lugs on the single-track hoist track. The cable hanging device includes:

[0007] A U-shaped connecting plate. Plug holes are provided on both side wall plates of the U-shaped connecting plate. Fixed holes are provided on the lifting lugs. The U-shaped connecting plate and the lifting lugs are detachably connected by a pin passing through the plug holes and the fixed holes, so that the U-shaped connecting plate is fixed above the single-track hoist track.

[0008] Support frames are symmetrically arranged on the outer sides of both side wall plates of the U-shaped connecting plate in an inclined manner. A plurality of cable limiting grooves are symmetrically arranged on the two support frames. Reinforcing ribs are provided between the support frames and the U-shaped connecting plate.

[0009] Preferably, the support frame is inclined upward with respect to the horizontal plane at the bottom of the U-shaped connecting plate, and the inclination angle range is 6-8°.

[0010] Preferably, the cable limiting groove is a semi-circular arc groove.

[0011] Preferably, the support frame and the cable limiting groove are connected by welding.

[0012] Preferably, the cable limiting grooves are evenly spaced on the support frame.

[0013] Preferably, the welding center distance between adjacent cable limiting grooves is 130 mm.

[0014] Preferably, the number of cable limiting grooves provided on each support frame is 5.

[0015] Preferably, it further includes a cable fixing clip which can be installed at the opening of the cable limiting groove for fixing the cable.

[0016] Preferably, a buffer layer is provided on the inner wall of the cable limiting groove.

[0017] Preferably, the support frame is an angle steel support frame.

[0018] Compared with the above background art, for a cable hanging device based on a single-track crane rail provided by the present utility model, when installing the single-track crane rail, the U-shaped connecting plate and the lifting ear plate are directly connected by using a pin at the same time. Since the step of drilling holes is omitted, the worker only needs to align the U-shaped connecting plate with the lifting ear plate and then insert the pin to complete the connection.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] In order to enable those skilled in the art in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figure 1 - Figure 2 , a cable hanging device based on a single - rail hoist track. There are lifting lugs on the single - rail hoist track. It further includes a U - shaped connecting plate 1. Pin holes 11 are provided on both side wall plates of the U - shaped connecting plate 1. Fixed holes are provided on the lifting lugs. The U - shaped connecting plate 1 and the lifting lugs are detachably connected by a pin passing through the pin holes 11 and the fixed holes, so that the U - shaped connecting plate 1 is fixed above the single - rail hoist track; support frames 2, symmetrically arranged obliquely on the outer sides of both side wall plates of the U - shaped connecting plate 1. A plurality of cable limiting grooves 3 are symmetrically provided on the two support frames 2. A reinforcing rib 4 is provided between the support frame 2 and the U - shaped connecting plate 1.

[0027] Specifically, the single - rail hoist track is used for mobile transportation equipment. The lifting lugs provided thereon not only serve as the installation foundation for the single - rail hoist track but also provide the installation foundation for the cable hanging device;

[0028] The pin holes opened on both side wall plates of the U - shaped connecting plate match the fixed holes on the lifting lugs, and are detachably connected by a pin, which is convenient for installation and disassembly, and further realizes the stable setting of the U - shaped connecting plate above the single - rail hoist track;

[0029] The support frames are symmetrically arranged obliquely on the outer sides of the left and right side wall plates of the U - shaped connecting plate. The cable limiting grooves symmetrically provided on the support frames are used to fix and limit the position of the cable to ensure the safety and stability of the cable.

[0030] With a cable hanging device based on a single-rail hoist track provided by this application, when installing the single-rail hoist track, a pin shaft is used to directly connect the U-shaped connecting plate and the lifting ear plate at the same time. Since the drilling step is omitted, the worker only needs to align the U-shaped connecting plate with the lifting ear plate and then insert the pin shaft to complete the connection. Therefore, it is applicable to the underground environment where the cable hanging device needs to be quickly deployed and removed. Due to the connection method enabling rapid installation and disassembly, the operation efficiency is improved and the labor intensity of workers is reduced. Since the cable hanging device is installed above the single-rail hoist track, mutual interference is avoided and it will not have any impact on the normal transportation function of the single-rail hoist track. Thus, the underground space is fully utilized, enabling the cables to be orderly suspended above the track, reducing the cable accumulation on the ground or walls, and improving the cleanliness and safety of the operation environment.

[0031] Based on the above embodiment, the support frame 2 is inclined upward compared to the bottom horizontal plane of the U-shaped connecting plate 1, and the inclination angle range is 6 - 8°. Preferably, the inclination angle of the support frame 2 of this application compared to the bottom horizontal plane of the U-shaped connecting plate 1 is 7°.

[0032] Specifically, the support frame 2 and the U-shaped connecting plate 1 are welded in an inclined upward manner, and its inclination angle is optimized and set to 7°, within the range of 6 - 8°. The inclined upward welding method effectively changes the force transmission path, helps reduce stress concentration in the U-shaped connecting plate and its nearby areas, thereby extending the service life and improving its stability.

[0033] Through inclined welding, the connection area and strength between the support frame 2 and the U-shaped connecting plate 1 are enhanced, enabling it to more effectively resist the vertically downward load and convert part of the load into the structural stability of the support frame itself.

[0034] Preferably, the support frame 2 of this application can be an angle steel support frame. The cross-sectional shape of the angle steel is L-shaped, and it has strong bending and torsion resistance and can maintain the structural stability under various working conditions. The angle steel support frame can be customized according to actual needs to adapt to the requirements of different scenarios and working conditions. At the same time, its dimensions and specifications are diverse, and it can meet the cable hanging requirements of different weights and spans.

[0035] Based on the above embodiment, the cable limiting groove 3 is a semi-circular arc groove; the support frame 2 and the cable limiting groove 3 are welded; the cable limiting grooves 3 are evenly spaced on the support frame 2.

[0036] Specifically, the semi-circular arc groove can closely fit the outer shape of the cable, providing effective support and protection for the cable. Through the constraint of the semi-circular arc groove, the cable is restricted to a specific position, ensuring the stability and safety of the cable.

[0037] The support frame 2 and the cable limiting groove 3 are connected by welding. Welding connection can ensure the firm connection between the support frame 2 and the cable limiting groove 3, and it is not easy to loosen or fall off even when bearing large loads or being impacted by external forces.

[0038] The cable limiting grooves 3 are evenly spaced on the support frame 2. The evenly spaced arrangement can make full use of the space of the support frame 2, enabling the cables to be arranged orderly in the limiting grooves, and avoiding the crossing and winding of the cables. The evenly spaced cable limiting grooves 3 make the cable management more convenient and efficient, and any cable problem can be quickly found and processed.

[0039] Based on the above embodiment, the welding center distance between adjacent cable limiting grooves 3 is 130 mm, and the diameters of all the cable limiting grooves 3 are 80 mm; the number of cable limiting grooves 3 provided on each support frame 2 is 5. The distance between the cable hanging devices is not greater than 3 m.

[0040] That is to say, the diameters of all the cable limiting grooves 3 are 80 mm, ensuring that the cables can slide freely in the grooves but not shake too much. The welding center distance between adjacent cable limiting grooves 3 is 130 mm. The selection of this distance takes into account the safety distance between the cables and the bearing capacity of the support frame. The appropriate distance can ensure that the cables will not be squeezed or wound around each other during the suspension process, and it is also convenient for the maintenance and replacement of the cables.

[0041] The number of cable limiting grooves 3 provided on each support frame 2 is 5. This number can be determined according to the actual requirements and the bearing capacity of the support frame.

[0042] The distance between the cable hanging devices is not greater than 3 m. This distance is set to ensure the stability and safety of the cables during the entire suspension process. An overly long distance may cause the cables to shake excessively under the action of wind or vibration, thus increasing the risk of cable damage.

[0043] Preferably, a buffer layer is provided on the inner wall of the cable limiting groove 3 to reduce the wear and scratches on the cable surface, thereby protecting the insulation layer and outer sheath of the cable from being damaged. The buffer layer material can include polymer materials such as rubber, polyurethane, and silica gel, which have good elasticity, wear resistance, and corrosion resistance and are suitable for the buffer layer of the cable limiting groove 3.

[0044] This application also provides an embodiment, which further includes a cable fixing clip. The cable fixing clip can be installed at the opening of the cable limiting groove 3 for fixing the cable.

[0045] Specifically, after the cable is laid, the cable can be fixed by a fixing clip. The cable fixing clip is usually installed at the opening of the cable limiting groove 3 to ensure that the cable can be effectively fixed after entering the limiting groove. The installation method can be a clamping type or a bolt fixing type, and the cable fixing clip can be a common spring clip.

[0046] In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
