Abstract
Description
Technical Field
[0001] This disclosure relates to the field of mine hoisting equipment, and more specifically, to a cage. Background Technology
[0002] In mining operations, cages are containers used to hoist ore, waste rock, and transport personnel, materials, and equipment; they are installed inside vertical shafts. The confined space, poor ventilation, and insufficient lighting within shafts present numerous challenges for maintenance work. Maintenance personnel must operate within this limited space and are easily affected by the surrounding environment. Furthermore, there is a risk of falling objects from height during shaft maintenance work, such as tools, parts, and ore, which could cause serious injury to maintenance personnel and threaten personnel and equipment below. Utility Model Content
[0003] The purpose of this disclosure is to provide a cage that improves the safety of personnel performing maintenance within the cage.
[0004] To achieve the above objectives, this disclosure provides a cage, comprising:
[0005] The cage body has a receiving cavity with an opening at the top;
[0006] A protective cover, installed above the cage body, includes a protective plate positioned opposite the opening of the receiving cavity, for preventing objects above the protective plate from falling into the receiving cavity; and
[0007] A hoisting rope for connecting to the outside is attached to the top of the cage body. The protective plate is provided with a first clearance opening for avoiding the hoisting rope, wherein one end of the first clearance opening is located at the edge of the protective plate and the other end is located at the center of the protective plate.
[0008] Optionally, the protective cover further includes a cover plate movably connected above the protective plate, the cover plate being able to at least partially cover the first clearance opening when in contact with the protective plate.
[0009] Optionally, a hinge is provided at the edge of the protective plate, and the cover plate is hinged to the protective plate via the hinge.
[0010] Optionally, the protective cover includes a plurality of spaced-apart support tubes, the two ends of which are respectively connected to the protective plate and the cage body.
[0011] Optionally, the cage body includes a plurality of connecting sleeves that correspond one-to-one with the support pipe. The connecting sleeves can be sleeved on the outside of the support pipe. The cage includes fasteners that can be inserted through the connecting sleeves to tighten the support pipe.
[0012] Optionally, the protective cover includes a multi-faceted protective curtain, the top of which is connected to the protective plate, and each of the protective curtains is retractably connected to the support tube.
[0013] Optionally, the protective curtain includes:
[0014] Multiple protective rods, each of which is slidably connected at both ends to two adjacent support tubes;
[0015] The first connecting chain connects one end to the protective plate and the other end to the uppermost protective rod; and
[0016] The second connecting chain connects two adjacent guard bars at both ends.
[0017] Optionally, a connecting ring is formed at the edge of the protective rod, and the connecting ring is sleeved on the support tube.
[0018] Optionally, the lengths of the first connecting chain and the second connecting chain are no greater than 40cm.
[0019] Optionally, the cage body is used to be positioned between two adjacent cage guides, the area of the protective plate is larger than the area of the opening of the receiving cavity, and a second clearance opening is formed at the edge of the protective plate to avoid the cage guide.
[0020] By implementing the above technical solution, a protective cover is installed on the cage body. Since the cage body forms a cavity to hold personnel or materials, the protective cover, covering the top opening, provides maintenance personnel with a relatively independent working space, improving the working environment. The protective plate can block falling objects (such as gravel, tools, etc.) from above, preventing them from directly falling into the cavity and causing injury or damage. This effectively improves the cage's safety performance, reduces the safety risks caused by falling objects, and increases maintenance efficiency. The first avoidance opening can also be used to temporarily install or replace protective plates when the cage body is already suspended in the shaft, facilitating personnel to perform construction and maintenance within it.
[0021] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation
[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0030] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are defined in relation to the actual arrangement direction of the cage during use, and directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and do not imply sequentiality or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.
[0031] According to one embodiment of this disclosure, such as Figures 1 to 4 As shown, a cage is provided, including a cage body 1 and a protective cover 2. The cage body 1 forms a receiving cavity with an opening at the top. The protective cover 2 can be installed above the cage body 1. The protective cover 2 includes a protective plate 21, which is disposed opposite to the opening of the receiving cavity to prevent objects above the protective plate 21 from falling into the receiving cavity. The cage may include a hoisting rope 3 for connection to the outside, where the hoisting rope 3 can be connected to a hoist. The hoisting rope 3 is connected to the top of the cage body 1. The protective plate 21 is provided with a first clearance opening 211 for avoiding the hoisting rope 3, wherein one end of the first clearance opening 211 is located at the edge of the protective plate 21, and the other end is located at the center of the protective plate 21.
[0032] Through the above technical solution, a protective cover 2 is installed on the cage body 1. Since the containment cavity formed by the cage body 1 is used to carry personnel or materials, the protective cover 2, which covers the top opening, can provide maintenance personnel with a relatively independent working space, improving the working environment. Its protective plate 21 can block objects falling from above (such as gravel, tools, etc.) to prevent them from falling directly into the containment cavity and causing injury or damage, effectively improving the safety protection performance of the cage, reducing the safety risks caused by falling objects, and improving the efficiency of personnel maintenance. The setting of the first avoidance opening 211 can also temporarily install or replace the protective plate 21 when the cage body 1 has been hoisted into the shaft 5, facilitating personnel to carry out construction and maintenance within it.
[0033] Specifically, since the hoisting rope 3 is positioned in the middle of the cage body 1, when installing the protective plate 21, the cage body 1 can be connected to the hoisting rope 3 and the outside first, and then the protective plate 21 can be directly installed on the cage body 1. The hoisting rope 3 can directly enter the center of the protective plate 21 from the edge of the first clearance opening 211, without having to pass the hoisting rope 3 through the protective plate 21 before connecting it to the hoist or the cage body 1. In this way, even when the cage body 1 is already hoisted in the shaft 5, the protective plate 21 can be temporarily installed or replaced, facilitating personnel to carry out construction and maintenance within it.
[0034] Furthermore, such as Figure 3 As shown, the protective cover 2 may also include a cover plate 22 movably connected above the protective plate 21. The cover plate 22 can at least partially cover the first clearance opening 211 when in contact with the protective plate 21. Since space needs to be left for the hoisting rope 3, the cover plate 22 cannot completely cover the first clearance opening 211. While ensuring that the hoisting rope 3 does not contact the cover plate 22, the area of the cover plate 22 can be increased as much as possible to cover the first clearance opening 211 as much as possible. Taking the cover plate 22 as a hinge to the protective plate 21 as an example, after the protective plate 21 has been installed on the cage body 1, rotating the cover plate 22 to fasten it onto the protective plate 21 can block most of the position of the first clearance opening 211, preventing falling debris such as gravel from entering the containment cavity through the first clearance opening 211 and injuring personnel inside, thus improving the protective effect. When it is necessary to disassemble or replace the protective plate 21, simply rotate the cover plate 22 to open it, and the protective plate 21 can be pulled out for replacement. The edge of the protective plate 21 may be provided with a hinge 221, and the cover plate 22 is hinged to the protective plate 21 through the hinge 221. The cover plate 22 can also be connected to the protective plate 21 through a hinge, or the cover plate 22 can be connected to the protective plate 21 by a snap fastener. When it is necessary to cover the position of the first clearance opening 211, it is fastened to the protective plate 21 by the snap fastener. When it is necessary to install the hoisting rope 3, the snap fastener is released to expose the entire first clearance opening 211. This disclosure does not limit this.
[0035] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, the protective cover 2 includes multiple spaced-apart support tubes 23, with both ends of each support tube 23 connected to the protective plate 21 and the cage body 1, respectively. The spaced-apart support tubes 23 form a rigid support frame, enhancing the overall stability and impact resistance of the protective cover 2. Furthermore, the structure of the support tubes 23 facilitates the modular installation and disassembly of the protective cover, adapting to the needs of cages of different sizes.
[0036] Here, the support pipe 23 can be welded to the cage body 1, or the cage body 1 can include multiple connecting sleeves 11 corresponding to the support pipe 23. The connecting sleeves 11 can be sleeved on the outside of the support pipe 23. The cage includes fasteners 20, which can be inserted through the connecting sleeves 11 to tighten the support pipe 23. In this way, the distance between the protective plate 21 and the cage body 1 can be adjusted by adjusting the position of the support pipe 23. The fasteners 20 can be bolts or threaded rods with nuts, and can be single or multiple, installed on the connecting sleeves 11. This disclosure does not limit this. Here, the length of the support pipe 23 can be set to 2m to 3m. This disclosure also does not limit this.
[0037] Furthermore, such as Figure 1 and Figure 2 As shown, the protective cover 2 may include multi-faceted protective curtains 24, with a protective plate 21 connected to the top of each curtain 24. Each curtain 24 is retractably connected to a support tube 23. The function of the protective curtains 24 is to prevent personnel from accidentally falling out of the gap between the protective plate 21 and the cage body 1, ensuring maintenance safety. The protective curtains 24 may be a mesh structure or a structure with protective rods 241 and connecting chains as described below; this disclosure does not limit this.
[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the protective curtain 24 may include multiple protective rods 241, a first connecting chain 242, and a second connecting chain 243. The two ends of each protective rod 241 can be slidably connected to two adjacent support tubes 23.
[0039] One end of the first connecting chain 242 is connected to the protective plate 21, and the other end is connected to the uppermost protective rod 241. The two ends of the second connecting chain 243 are connected to two adjacent protective rods 241. The function of the first connecting chain 242 is to limit the movement range of the uppermost protective rod 241. When the uppermost protective rod 241 moves upward, the first connecting chain 242 does not limit its movement. When the uppermost protective rod 241 moves downward to the length of the first connecting chain 242, the first connecting chain 242 tightens to prevent the uppermost protective rod 241 from moving further downward, thus ensuring that the gap between the uppermost protective rod 241 and the protective plate 21 does not exceed the length of the first connecting chain 242. Similarly, when the lower protective rod 241 moves downward to the length of the upper connecting chain 243, the second connecting chain 243 tightens to prevent the connected protective rod 241 from moving further downward, ensuring that the gap between two adjacent protective rods 241 does not exceed the length of the second connecting chain 243. Here, the structure of the first connecting chain 242 and the second connecting chain 243 can be a structure formed by connecting multiple iron rings end to end. When the operator needs to leave the cage body 1, he only needs to lift the lowest guard bar 241 and move it upward until the gap between the protective curtain 24 and the cage body 1 is large enough for personnel to pass through. There can be multiple first connecting chains 242, which are spaced apart between the protective plate 21 and the uppermost guard bar 241. Similarly, there can be multiple second connecting chains 243 between every two adjacent guard bars 241. The specific number can be set according to actual needs, and this disclosure does not limit it.
[0040] Regarding the connection between the protective rod 241 and the support tube 23, a slide rail can be formed on the support tube 23, and the edge of the protective rod 241 can be engaged and moved within the slide rail. Alternatively, a connecting ring 244 can be formed on the edge of the protective rod 241, and the connecting ring 244 can be sleeved on the support tube 23. When the protective rod 241 is moved, the connecting ring 244 can slide on the support tube 23. This ensures both the movement of the protective rod 241 and prevents it from falling off the connecting ring 244. This disclosure does not limit the scope of the invention.
[0041] It should be noted that the lengths of the first connecting chain 242 and the second connecting chain 243 are no more than 40cm. This ensures that when the lowest guard bar 241 is pulled to its lowest point, the distance between adjacent guard bars 241 within the protective curtain 24 is no more than 40cm. This distance is sufficient to prevent personnel from accidentally falling out while also not hindering the delivery of tools between the inside and outside of the protective curtain 24.
[0042] According to one embodiment of this disclosure, such as Figure 3 and Figure 4As shown, the cage body 1 is usually set between two adjacent guide rails 4. At this time, the area of the protective plate 21 is larger than the area of the opening of the receiving cavity, which can expand the protection range. A second clearance opening 212 is formed at the edge of the protective plate 21 to avoid the guide rails 4, avoid interference with the guide rails 4, and ensure that the cage body 1 can run smoothly along the shaft 5.
[0043] In addition, during the actual setup process, a vertical shaft ladder 6 can be installed in the shaft 5 to allow personnel to go up and down when the hoisting equipment fails. At the same time, the cage is connected to a cage counterweight 7 for balancing the weight, so that the cage moves more smoothly and prevents imbalance.
[0044] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0046] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
