Description

Technical Field

[0001] The utility model belongs to the technical field of transfer machine equipment, and particularly relates to a pedestrian bridge tooling for a transfer machine. Background Art

[0002] In order to ensure the personal safety of underground employees, personnel are not allowed to cross and slide into the working face in the fully-mechanized top coal caving working face. According to the new safety production requirements, the fully-mechanized top coal caving working face must achieve "two unblocked", that is, the equipment of the chute belt lane must be arranged on the working face side, and the chute lane belt conveyor and the transfer machine, crusher, end bracket and other equipment of the working face are all arranged on the working face side. The pedestrian passage is arranged on the lower side. For this reason, we have designed a pedestrian bridge at the tail of the transfer machine and the middle of the end bracket through multiple measurements and discussions, which not only ensures that underground employees can safely pass through to enter the working face, but also does not affect the normal production shift coal output, and has a strong practicality. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide a transfer machine pedestrian bridge tooling for assisting underground workers to safely enter the working face from the pedestrian side of the lower gangway.

[0004] The utility model is realized by adopting the following technical solutions:

[0005] A pedestrian bridge tooling for a transfer machine includes a pair of angle steels, a pair of steel plates, and at least a pair of handrails. A steel plate is fixed to a right-angled side of an angle steel in the same plane or overlapped with each other. Both ends of the steel plate parallel to the length direction of the angle steel are provided with at least one mounting hole. At least one handrail is rotatably mounted on the inner side of another right-angled side of the angle steel.

[0006] When in use, a pair of steel plates are relatively fixed on the transfer machine through the mounting holes. After installation, the pair of steel plates form a plane for underground workers to pass through, and the railings are rotated to a position perpendicular to the steel plates, making it convenient for underground workers to safely enter the working face from the pedestrian side of the lower gang.

[0007] Further preferably, a through hole 1 perpendicular to the railing is opened at the lower part of the railing, and through holes 2 for fixing the railing are opened at two right-angled sides of the angle steel, and the axes of through holes 1 and 2 are made to coincide by rotating the railing.

[0008] Further preferably, the length of the angle steel is 1.4 to 1.6 meters.

[0009] Further preferably, the railing includes a plurality of flat steels and a plurality of 6-branch pipes, the flat steels are installed vertically at intervals along the angle steel and are laterally rotated on the inner side of another right-angled side of the angle steel, and the 6-branch pipes are fixed horizontally at intervals on the flat steel and are located on the outer side of the angle steel. A through hole 1 is provided at the lower part of the flat steel, and two through holes for fixing the flat steel are provided perpendicular to the two right-angled sides of the angle steel, and the axes of the through holes 1 and 2 are made to coincide with each other by rotating the flat steel.

It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0022] A symmetrical arrangement of a pedestrian bridge tooling for a transfer machine comprises a pair of angle steels 1, a pair of steel plates 2, and a pair of handrails 3. A steel plate 2 is fixed to a right-angled side of an angle steel 1 in the same plane or overlapped therewith. Two mounting holes 4 are provided at both ends of the steel plate 2 parallel to the length direction of the angle steel 1. A handrail 3 is rotatably mounted on the inner side of another right-angled side of an angle steel 1, and the handrail 3 rotates within the right-angle range of the angle steel 1.

[0023] There may be an embodiment such as Figure 1 As shown, this embodiment uses a 1.46-meter-long 10# angle steel 1, a 1.46-meter-long 10mm steel plate 2, and a railing 3 including a plurality of 10# flat steels 5 and a plurality of 6-branch pipes 6. The 10# flat steels 5 are installed vertically and horizontally along the 10# angle steel 1 at intervals on the inner side of another right-angled side of the angle steel 1, and the 6-branch pipes 6 are fixed horizontally on the 10# flat steel 5 at intervals and are located on the outer side of the angle steel 1. A through hole 1 (not shown in the figure) is provided at the lower part of the flat steel 5, and a through hole 2 (not shown in the figure) is provided perpendicular to the two right-angled sides of the angle steel 1 for fixing the flat steel 5. When the flat steel 5 is rotated to the right-angled side close to the angle steel 1, that is, when the axes of the through hole 1 and the through hole 2 coincide, it is locked with bolts, so that the flat steel 5 and the right-angled side of the angle steel 1 can be connected as a whole, and the flat steel 5 can be fixed.

[0024] There can also be an embodiment, such as Figure 3 As shown, the steel plate 2 is welded to a right-angled side of the angle steel 1, and the railing 3 is rotatably installed on the inner side of the other right-angled side of the angle steel 1. A pair of mounting holes 4 of the steel plates 2 are fixed to the transfer machine through bolts. After installation, a pair of steel plates 2 form a plane for underground workers to pass through. The railing 3 is rotated to a position perpendicular to the steel plates 2 and fixed by bolts to form a pedestrian bridge.

[0025] like Figure 4 As shown, after the underground workers enter the working surface from the pedestrian side of the lower gang, the railing 3 is rotated to a position parallel to the steel plate 2, the bolts fixing the steel plate 2 are removed, and the through hole 2 (not shown in the figure) of the other right-angle side of a pair of angle steels 1 is passed through the bolts and fixed to both sides of the transfer machine. At this time, the through hole 1 (not shown in the figure) on the railing 3 rotated to a position parallel to the steel plate corresponds exactly to the through hole 2 of a right-angle side of the angle steel, and the through hole 1 and the through hole 2 are locked by bolts.

[0026] Figure 4 After the steel plate 2 in the middle is erected, it can be used as a coal blocking plate to undertake the task of blocking coal, which can not only protect the utility model from being bumped and lost, but also solve the demand of the production shift transfer machine to pull large pieces of coal.

[0027] The utility model can protect underground workers from entering the working face safely, thus improving the safety standardization of safe production.

[0028] The above is only a specific implementation of the utility model, which enables those skilled in the art to understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
