Description

Technical Field

[0001] This utility model relates to the field of single-rope skip fall prevention technology, specifically to a vertical shaft single-rope skip. Background Technology

[0002] A skip is a container used to directly load minerals, waste rock, or gangue. There are two types: those for inclined shafts and those for vertical shafts. Main shaft skips are further classified into single-rope skips and multi-rope skips depending on the type of hoist. According to the patent search, Chinese Patent Publication (Announcement) No. CN221796701U discloses a single-rope skip for vertical shafts. The rope lifting ring used in this patent is relatively simple and lacks anti-fall insurance. Under high-intensity use, the rope lifting ring bearing is prone to deformation due to stress, which may lead to breakage and cause a major safety hazard in the use of the skip.

[0003] Therefore, a vertical shaft single-rope skip is required. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a single-rope skip for vertical shafts. The purpose is to provide a fall protection mechanism for the skip during use. In the event of a breakage or detachment of the rope shackle from the skip's connecting shaft, the fall protection component adds an extra layer of safety protection during skip hoisting, ensuring that the skip can be transported normally while preventing major safety accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical shaft single-rope skip, comprising a main frame and a skip. The skip is supported in the middle of the main frame. A hoisting rope ring is installed on the top of the main frame via a connecting shaft assembly. Shaft bases are symmetrically arranged on both sides of the hoisting rope ring. A shaft cylinder is located in the middle of the shaft base. The shaft cylinder is connected to the shaft base via a pin and a cotter pin. A shaft rod is connected to one side of the shaft cylinder. A limiting plate is set at the bottom of the shaft rod. A pull rod is sleeved on the shaft rod. The pull rod is limited by the limiting plate to prevent it from detaching from the shaft rod. The main frame on both sides of the hoisting rope ring is symmetrically arranged as a fixed base. A shaft cylinder is connected to the fixed base via a pin and a cotter pin. A shaft rod is connected to one side of the shaft cylinder. A limiting plate is set at the top of the shaft rod. The top of the shaft rod is sleeved inside the pull rod. The shaft rod is limited by the limiting plate to prevent it from detaching from the pull rod.

[0006] Preferably, connecting plates are evenly provided on the opposite side surfaces of the first and second limiting plates. A pin hole is opened at the overlapping part of the connecting plates. The first pin hole extends to both sides, so that a second pin hole is opened on the tie rod cylinder. The first pin hole and the second pin hole are connected by a pin and a cotter pin, which further increases the installation strength of the shaft, the second shaft and the tie rod cylinder.

[0007] Preferably, the connecting shaft assembly includes two fixed plates symmetrically mounted on the top of the main frame, with a connecting shaft one welded to the middle of the fixed plates, and the connecting shaft one being movably connected to the bottom of the suspension rope ring.

[0008] Preferably, the shaft base consists of two sets of four shafts installed on both sides of the lifting rope ring.

[0009] In summary, this utility model provides a single-rope skip for vertical shafts, which allows the tie rod cylinder to be connected to shaft one and shaft two respectively. By installing the tie rod cylinder, shaft one, and shaft two between the hoisting rope ring and the main frame, the safety problem of the skip falling due to deformation and breakage of the connecting shaft assembly is prevented. By installing anti-fall components on both sides of the hoisting rope ring, loading can continue to be completed while ensuring the safe use of the skip, thus ensuring the efficiency of coal transportation.

[0010] It provides fall-prevention support, effectively ensuring the safe transport and use of skips; by monitoring the load changes of the wire rope pulleys of single-rope skip hoisting in real time and collecting data through sensors, it can accurately determine the loading and unloading status of the lifting container, detect faults such as uneven stress and loose ropes, effectively monitor safety issues such as loose wire ropes or single rope overload damage, and promptly repair the connecting shaft assembly or lifting rope rings after the skip has been safely transported and used, preparing for the next safe loading and use.

[0011] This design prevents the risk of breakage of the connecting shaft assembly under individual stress. By installing a tie rod sleeve between shaft one and shaft two, the safety of preventing falls is effectively ensured, allowing the skip to be transported normally and enabling timely replacement and maintenance, thus solving the safety problem of skip falling.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figures 1 to 4 As shown: This utility model is a vertical shaft single-rope skip. In order to ensure the safe use of the skip and prevent the connection between the hoisting rope ring 3 and the connecting shaft 23 from breaking and detaching, axle rod 6, axle rod 14 and tie rod cylinder 11 are added on both sides of the main frame 1 to ensure the safety of the skip during hoisting and to ensure that the skip can continue to be loaded and used normally.

[0015] The technical structure adopted in this patent is as follows: it includes a main frame 1 and a skip 2. The skip 2 is supported in the middle of the main frame 1. A suspension rope ring 3 is installed on the top of the main frame 1 through a connecting shaft assembly. A shaft base 4 is symmetrically set on both sides of the suspension rope ring 3. A shaft cylinder 5 is located in the middle of the shaft base 4. The shaft cylinder 5 and the shaft base 4 are connected by a pin and a cotter pin. A shaft rod 6 is connected to one side of the shaft cylinder 5. A limiting plate 7 is set at the bottom of the shaft rod 6. A pull rod cylinder 11 is sleeved on the shaft rod 6. The pull rod cylinder 11 is connected by a limiting plate. Plate 7 limits and prevents the pull rod cylinder 11 from detaching from the shaft rod 6. The main frame 1 on both sides of the rope ring 3 is symmetrically set as fixed base 12. The fixed base 12 is connected to the shaft cylinder 13 through a pin and a cotter pin. One side of the shaft cylinder 13 is connected to the shaft rod 14. The top of the shaft rod 14 is set as a limiting plate 15. The top of the shaft rod 14 is sleeved inside the pull rod cylinder 11. The shaft rod 14 is limited and installed inside the pull rod cylinder 11 by the limiting plate 15 to prevent the shaft rod 14 from detaching from the pull rod cylinder 11.

[0016] Specifically: such as Figures 1 to 2 As shown; The skip 2 is located in the middle of the main frame 1. The main frame 1 supports and loads the skip 2, ensuring its safe transport. A connecting shaft assembly is located on the upper part of the main frame 1. This assembly is installed with the lifting rope ring 3 to lift and load the skip 2 and the main frame 1. To prevent deformation and breakage of the connecting shaft assembly, which could cause the skip 2 to fall, shaft bases 4 are welded to both sides of the lifting rope ring 3. Fixed bases 12 are welded to both sides of the top of the main frame 1. A second shaft cylinder 13 is connected to the fixed base 12 via pins and cotter pins. A first shaft cylinder 5 is connected to the shaft base 4 via pins and cotter pins. A first shaft rod 6 is connected to one side of the first shaft cylinder 5, and a second shaft rod 14 is connected to one side of the second shaft cylinder 13. A tie rod cylinder 11 is connected to shaft 6 and shaft 14 via a common sleeve. A limiting plate 7 is welded to the end of shaft 6, and a limiting plate 15 is set at the end of shaft 14. Through a hot and cold process, the limiting plates 7 and 15 are respectively engaged with the two sides of the tie rod cylinder 11, so that the tie rod cylinder 11 is engaged with shaft 6 and shaft 14 respectively. The tie rod cylinder 11, shaft 6, and shaft 14 are installed between the hoisting rope ring 3 and the main frame 1, which prevents the skip 2 from falling due to deformation and breakage of the connecting shaft assembly. By installing anti-fall components on both sides of the hoisting rope ring 3, loading can continue to be completed while ensuring the safe use of the skip 2, thus ensuring the efficiency of coal transportation.

[0017] During loading and transportation, the hoisting rope ring 3 is connected to the tail rope suspension device. The hoisting rope ring 3 and the connecting shaft assembly mainly bear the lifting force, while shaft 1 6 and shaft 2 14 are in a non-stressed state. The tie rod cylinder 11 is sleeved between shaft 1 6 and shaft 2 14 and is used for the installation of a fall arrestor to protect against the risk of falling. If the connecting shaft assembly breaks, shaft 1 6 and shaft 2 are used for hoisting on both sides of the hoisting rope ring 3. Shaft 1 6 and shaft 2 are connected by the tie rod cylinder 11 to achieve fall arrest support, effectively ensuring the safe transport and use of the skip 2. By monitoring the load changes of the wire rope wheel of the single-rope skip in real time and collecting data through sensors, the loading and unloading status of the lifting container can be accurately determined, and faults such as uneven force and loose rope can be detected. It can effectively monitor safety issues such as loose wire rope or single rope overload damage. After the skip 2 is safely transported and used, the connecting shaft assembly or hoisting rope ring 3 can be repaired in time to prepare for the next safe loading and use.

[0018] In at least one embodiment, such as Figure 3 As shown; To further enhance the strength of the fall arrestor components and distribute the load on the connecting shaft components, connecting plates 16 are evenly distributed on the opposite side surfaces of the first limiting plate 7 and the second limiting plate 15. A pin hole 17 is formed at the overlapping point of the connecting plates 16. The pin hole 17 extends to both sides, forming a pin hole 21 on the tie rod cylinder 11. The pin hole 17 and the pin hole 21 are connected by a pin and a cotter pin, further increasing the installation strength of the shaft 6, the second shaft 14 and the tie rod cylinder 11.

[0019] Specifically, the two connecting plates 16 are connected by a pin and a cotter pin, so that the first shaft 6, the second shaft 14 and the connecting shaft assembly share the lifting force, preventing the risk of the connecting shaft assembly breaking under stress alone. The tie rod cylinder 11 is installed between the first shaft 6 and the second shaft 14, which effectively ensures that the fall prevention problem occurs, and ensures that the skip 2 can be transported normally in a timely manner, and allows for timely replacement and maintenance, thus solving the safety problem of the skip 2 falling.

[0020] In at least one embodiment, such as Figure 1 and Figure 4 As shown; The specific assembly relationship between the suspension ring 3 and the connecting shaft assembly is as follows: the connecting shaft assembly includes two fixed plates 22 symmetrically installed on the top of the main frame 1, a connecting shaft 23 is welded to the middle of the fixed plates 22, and the connecting shaft 23 is movably connected to the bottom of the suspension ring 3.

[0021] In at least one embodiment, such as Figure 1 As shown; The shaft base 4 uses two sets of four units installed on both sides of the lifting rope ring 3, which realizes the balanced lifting of the skip 2 for loading and transportation.

[0022] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
