Description

A tail rope protection device Technical Field

[0001] This utility model relates to the field of vertical shaft hoisting technology, and in particular to a tail rope protection device. Background Technology

[0002] Vertical shafts typically use multi-rope friction wheel hoists to lift and transport minerals within the mine. The hoisting method is a cage + counterweight. The working principle is that a steel wire rope is looped on the main guide wheel, with a hoisting container suspended at each end. The steel wire rope is driven by the friction between the pads installed on the main guide wheel and the steel wire rope, which moves the hoisting container and thus completes the task of lifting or lowering heavy objects.

[0003] In multi-rope hoisting systems, the tail rope plays a crucial balancing role, reducing the static tension difference in the wire ropes by varying its weight to achieve system balance. However, when hoisting fully loaded mine cars in various intermediate sections, some ore inevitably rolls down into the shaft, directly damaging equipment such as the tail rope switch at the bottom of the shaft. Furthermore, the tail rope experiences significant swaying during hoisting and transportation, making it prone to friction and knotting, resulting in poor stability. Therefore, a protective device is urgently needed to safeguard the internal structure and prevent tail rope swaying. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a tail rope protection device that can effectively support falling rocks and minerals, and can also limit the tail rope during use to prevent it from rubbing and knotting.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a tail rope protection device, comprising a protective frame in the shape of a grid, two sets of tail ropes are provided inside the protective frame, a tail rope switch is provided on the outside of the protective frame, a limiting wheel is provided between the two sets of tail ropes, and fixed plates extending outward are provided on both sides of the protective frame, the distance between the fixed plates and the protective frame is adjustable.

[0006] Preferably, the protective frame includes three I-beams and multiple anti-collision beams, with the three I-beams arranged in parallel and the multiple anti-collision beams fixed at intervals within the three I-beams.

[0007] Preferably, round logs are provided above both the I-beam and the anti-collision beam, and the round logs are fixed to the I-beam and the anti-collision beam by through bolts.

[0008] Preferably, the middle anti-collision beam is provided with fixed ear plates on both sides, and the limiting wheel is rotatably connected to the fixed ear plates. Under normal conditions, the tail rope does not contact the limiting wheel.

[0009] Preferably, a threaded sleeve is provided on one side of the fixed plate, and an extended screw is provided on the outer wall of the outermost anti-collision beam. The threaded sleeve cooperates with the screw, and the distance between the fixed plate and the protective frame is adjusted by the threaded sleeve and the screw.

[0010] Preferably, the limiting wheels are symmetrically arranged on both sides of each set of tail ropes, and under normal conditions, the tail ropes are lifted and run between the two limiting wheels.

[0011] This utility model discloses a tail rope protection device, comprising a grid-shaped protective frame, two sets of tail ropes inside the protective frame, a tail rope switch on the outer side of the protective frame, a limiting wheel between the two sets of tail ropes, and outwardly extending fixing discs on both sides of the protective frame.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] Referring to Figures 1-3, a tail rope protection device includes a protective frame 1 in the shape of a grid. The protective frame 1 has two sets of tail ropes 5 arranged in the space. Both ends of the two sets of tail ropes 5 are fixed with containers. The two containers are staggered one above the other. The top of the containers is fixed with a wire rope for winding and lifting. After the hoist is running, the two containers are lifted up and down alternately. The outer side of the protective frame 1 is provided with a tail rope switch 6. A limit wheel 10 is provided between the two sets of tail ropes 5. The two sides of the protective frame 1 are provided with outwardly extending fixing discs 9. The distance between the fixing discs 9 and the protective frame 1 is adjustable.

[0019] Since the tail rope 5 is located inside the grid-shaped protective frame, the space inside the frame can restrict the two sets of tail ropes, preventing them from getting tangled or rubbing against each other. When in use, the protective frame 1 is fixed to the shaft wall by the fixing plate 9 and bolts. The protective frame 1 can bear and buffer the ore or other falling objects in the shaft, and can effectively protect the tail rope switch.

[0020] Specifically, the protective frame 1 includes three I-beams 2 and multiple anti-collision beams 3. The three I-beams 2 are arranged in parallel, and the multiple anti-collision beams 3 are fixed at intervals within the three I-beams 2. The I-beams 2 and the anti-collision beams 3 are fixed together by welding, and the three I-beams 2 and the multiple anti-collision beams 3 form a grid-shaped protective frame 1.

[0021] To prevent ore or falling objects from directly impacting the I-beam 2 and the anti-collision beam 3, round logs 4 are installed above the I-beam 2 and the anti-collision beam 3. The round logs 4 are fixed to the I-beam 2 and the anti-collision beam 3 by through bolts. Therefore, the installation of round logs 4 can effectively buffer the ore or falling objects in the well, prevent the I-beam 2 and the anti-collision beam 3 from being deformed due to impact, and thus improve their service life.

[0022] In this embodiment, the log 4 is preferably a full-red pine log, which has the characteristics of being wear-resistant, not easily deformed, and resistant to decay.

[0023] The fixed plate 9 is provided with a coaxially fixed threaded sleeve 8 on one side, and the outermost anti-collision beam 3 is provided with an extended screw 7 on its outer wall. The threaded sleeve 8 and the screw 7 cooperate with each other. The fixed plate 9 can adjust the distance between itself and the protective frame 1 through the threaded sleeve 8 and the screw 7. This makes it easier to fix the whole in the shaft and improve its applicability in the shaft.

[0024] In addition, fixed ear plates 31 are provided on both sides of the anti-collision beam 3 in the middle. The limiting wheel 10 is rotatably connected to the fixed ear plates 31. Under normal conditions, the tail rope 5 does not contact the limiting wheel 10.

[0025] In this embodiment, the circumference of the limiting wheel 10 is provided with an arc-shaped groove to limit the deviation of the tail rope.

[0026] Please refer to Figure 2-3 again. The limit wheel 10 is located on both sides of the middle anti-collision beam 3, that is, between the two sets of tail ropes 5. During the lifting operation, the tail rope 5 does not contact the limit wheel 10 to avoid friction and wear between the limit wheel 10 and the tail rope 5. When the two sets of tail ropes 5 swing or deviate from each other during the lifting operation, the tail rope 5 will contact the limit wheel 10. At this time, the limit wheel 10 starts to rotate with the lifting and plays a corrective role, further preventing the two sets of tail ropes from getting tangled or rubbing.

[0027] Based on the above embodiments, as shown in Figure 4, the limiting wheels 10 can also be symmetrically arranged on both sides of each set of tail ropes 5. Under normal circumstances, the tail ropes 5 also do not contact the limiting wheels 10 on both sides.

[0028] In other words, during the lifting process, the tail rope 5 runs between the two limit wheels 10; once the tail rope deviates, it will contact one of the limit wheels 10, and the contacting limit wheel will limit the tail rope, thereby increasing the degree of limit and meeting the requirements for stable lifting.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
