[0024] In order to make the above purpose, features and advantages of the utility model more apparent, obvious, below, specific implementation of the utility model is explained in detail with the drawings.

[0025] It needs to be explained that, in the description of the utility model, "upper", "lower", "top", "bottom", orientation or positional relationship is based on the attached Figure 1 It needs to be understood that, these orientation terms are only for the convenience of describing the utility model and simplifying the description, and are not indicated or implied that the indicated device or element must have a particular orientation, is constructed and operated in a particular orientation, therefore, it cannot be understood as the limitation of the utility model.

[0026] In one embodiment, as Figure 1 , Figure 2 and Figure 3 Indicated, the temporary ladder track for mine internal transportation of quick dismounting, including two I -shaped steel rails 100 for carrying mine transport vehicle movement and N channel steel sleepers 200 that can be embedded in coal cinder and / or coal powder in mine, 4≤N≤6.

[0027] Among them, I -shaped steel rail 100 refers to the metal track component with I -shaped section, specifically can adopt rolled steel material processing forming, and the web and flange form continuous bearing surface, for bearing the wheel pressure load of transportation equipment.Channel steel sleeper 200 refers to the support component made of channel steel material, specifically can adopt the channel steel section with opening downward arrangement, and is fixed through the side wall and the bite effect of coal cinder and / or coal powder.

[0028] In the embodiment, two I -shaped steel rails 100 are arranged in parallel, and any channel steel sleeper 200 is vertically fixedly connected with each I -shaped steel rail 100;All channel steel sleepers 200 are arranged on the bottom of I -shaped steel rail 100, and all channel steel sleepers 200 are arranged in alignment, and the distance between any two adjacent channel steel sleepers 200 is equal.The top of channel steel sleeper 200 is welded with the bottom of I -shaped steel rail 100.

[0029] Both ends of the two I-shaped steel rails 100 are provided with alignment holes 110 for alignment when different ladder-shaped tracks are installed, and the other ends of the two I-shaped steel rails 100 are provided with alignment columns 120 which can be matched and inserted into the alignment holes 110.

[0030] Specifically, the alignment hole 110 refers to a circular through hole arranged at the end of the track, which can be formed by drilling or stamping process, and is used to form a plug-in fit with the alignment column 120 of the adjacent track. The alignment column 120 refers to a cylindrical protrusion matched with the alignment hole 110, which can be a metal column fixed by welding or bolts.

[0031] Specifically, the I-shaped steel rail 100 and the channel steel sleeper 200 form a rigid frame through vertical welding, forming a unitized ladder-shaped track unit. The channel steel sleepers 200 are arranged at equal intervals to form stable support points, which can be directly pressed into the coal cinder and / or coal powder layer to complete the foundation fixation. The butt joint between the track units is achieved through the plug-in structure, and when the alignment column 120 is inserted into the alignment hole 110 of the adjacent unit, the track end surface automatically forms a connection. This design eliminates the processes of sleeper positioning, track gauge measurement and joint adjustment in traditional construction, and realizes the immediate use of the track assembly.

[0032] The temporary ladder-shaped track for mine internal transportation in the embodiment can be quickly disassembled, and a plurality of channel steel sleepers 200 and I-shaped steel rails 100 are combined into an overall structure, which saves the on-site assembly process in the mine, and the equally distributed channel steel sleepers 200 replace the scattered sleepers laid by artificial, thereby ensuring the uniform distribution of support points. The alignment column 120 and the alignment hole 110 can achieve accurate and rapid alignment of the unitized ladder-shaped track. When the temporary ladder-shaped track for mine internal transportation in the embodiment is used to lay a temporary track, the track extension can be completed by the unitized ladder-shaped track unit through the splicing module, which greatly reduces the labor and construction time, and realizes the rapid deployment of the temporary track.

[0033] In one of the embodiments, the opening of the channel steel sleeper 200 faces downward, and a plurality of barb structures 210 are welded inside the channel steel sleeper 200. The barb structure 210 is triangular sawtooth-shaped, and the height of the barb structure 210 is 5 cm-10 mm, and the inclination angle is 30°-60°.

[0034] The opening downward refers to that the cross section of the channel steel sleeper 200 is U-shaped, and the opening direction is perpendicular to the installation base surface of the channel steel sleeper 200. When the channel steel sleeper 200 is embedded into the coal cinder and / or coal powder, a downward extending cavity is formed, and the cavity is filled with the coal cinder and / or coal powder under its own weight to increase the contact area. The barb structure 210 refers to a protruding part welded on the inner side wall of the channel steel sleeper 200, which can be formed by welding triangular sawtooth-shaped metal sheets at intervals, and the tip thereof is upwardly inclined, which is used to penetrate the coal cinder and / or coal powder particles to form a stable effect on the channel steel sleeper 200, thereby increasing the stability of the temporary track.

[0035] The traditional sleeper needs to be manually nailed with spikes or bound with steel belts for reinforcement after laying, and the present embodiment replaces the external fixing member with the friction fixing effect of the barbs and cinder and / or coal powder, omits the reinforcement process, and further improves the laying speed of the temporary track.

[0036] In one of the embodiments, the alignment hole 110 and the alignment column 120 are arranged on the top of the I-shaped steel rail 100, and the axes of the alignment hole 110 and the alignment column 120 are perpendicular to the channel steel sleeper 200.

[0037] In the present embodiment, the outer surfaces of the alignment column 120 and the alignment hole 110 are coated with a wear-resistant layer, and the length of the alignment column 120 is slightly longer than the distance of the alignment hole 110 by 4-6 mm. The alignment hole 110 and the alignment column 120 on the top of the I-shaped steel rail 100 form a vertical positioning reference, and the construction personnel only need to superimpose the end portions of the adjacent I-shaped steel rails 100 vertically when splicing the track, and the longitudinal butt joint can be completed by relying on the matching clamping of the hole and column, without the need for repeated calibration of the rail joint width with the aid of measuring tools, thereby eliminating human operation errors and improving the assembly efficiency.

[0038] In one of the embodiments, along the length direction of the I-shaped steel rail 100, the distance from the outermost channel steel rail to the end surface of the I-shaped steel rail 100 is half of the distance between the adjacent channel steel rails.

[0039] Specifically, the positioning distance of the outermost channel steel sleeper 200 refers to the distance from the end surface of the I-shaped steel rail 100 to the center line of the first channel steel sleeper 200, which is set to be half of the center distance between the adjacent channel steel sleepers 200, and is realized by adjusting the welding position.

[0040] The positioning distance of the outermost channel steel sleeper 200 is limited to half of the distance between the adjacent sleepers, so that when the adjacent track units are connected, the distance between the first sleeper and the last sleeper automatically recovers to the full sleeper distance, forming a continuous equidistant support system. When the transport vehicle passes through the track joint, this layout ensures that the wheel load can be evenly transmitted to the adjacent sleepers, avoiding track deformation due to the lack of end support.

[0041] In one of the embodiments, at least two mounting holes 300 for fixed assembly with the tie plate 400 are arranged at the two ends of any I-shaped steel rail 100. Figure 4 As shown in FIG. 4, the tie plate 400 based on the mounting hole 300 fixes and splices two adjacent unitized ladder tracks, and the fixing hole on the tie plate 400 is fixedly connected with the mounting hole 300 of the I-shaped steel rail 100 through a bolt.

[0042] Specifically, the fixing hole of the track clamp plate 400 can be designed after the two ladder-shaped track splices are completed in the embodiment.

[0043] Since the mounting hole 300 is precisely machined during the track manufacturing stage, the construction personnel do not need to adjust the track gauge or measure the hole position on site, and only need to fasten the bolt after aligning the track clamp plate 400 with the mounting hole 300 to complete the connection. At the same time, the multi-point fixing structure formed by at least two mounting holes 300 can disperse the shear force at the track joint to prevent the connection from loosening due to vibration during transportation.

[0044] In one embodiment, the length of the I-shaped steel rail 100 is 3.6m-4.8m, and the distance between the two I-shaped steel rails 100 is 0.6m-1.6m. The distance between any two channel steel sleepers 200 is 0.6m-1.2m, and the length of each channel steel sleeper 200 is 1m-2m.

[0045] The length and distance of the I-shaped steel rail 100 and the channel steel sleeper 200 described above can meet the requirements of the existing mainstream mine transport vehicle track and can adapt to the narrow space in the roadway.

[0046] In a specific embodiment, the number of channel steel sleepers 200 is 6, the length of the I-shaped steel rail 100 is 3.6m, and the distance between the two I-shaped steel rails 100 is 0.8m. The distance between any two channel steel sleepers 200 is 0.6m, and the length of each channel steel sleeper 200 is 1.2m. The channel steel sleeper 200 and the I-shaped steel rail 100 use the parameter settings of the embodiment, which is beneficial to the parking of the mainstream transport vehicle unit vehicle, can realize the laying or removal of the ladder-shaped track with the vehicle, and improves the flexibility of the temporary track laying.

[0047] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the scope of protection of the present application should be subject to the appended claims.
