[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Example:
[0023] like Figs. 1-3 As shown, this utility model provides a removable liner protection device for manholes.
[0024] The system includes a protective mechanism, a ore bin 1, and a liner 2. The liner 2 is disposed on the inner surface of the ore bin 1, and the protective mechanism is disposed on the surface of the liner 2. The protective mechanism is used to protect the surface of the liner 2. The protective mechanism includes a fixing device, a rail 3, and a chain 4. The rail 3 has a positioning hole, and the chain 4 has a through hole. The chain 4 and the rail 3 are fixedly connected by bolts 5 through the positioning hole and the through hole. The upper end of the chain 4 is fixedly connected to the upper end of the ore bin 1 through the fixing device.
[0025] The above-mentioned arrangement allows the protective device to be securely installed inside the mine bin 1, providing effective protection for the liner 2, while also facilitating disassembly and maintenance.
[0026] Optionally, the fixing device includes a fixing rod 6 and a fixing seat 7. The iron chain 4 is sleeved on the fixing rod 6 through the through hole. The upper end of the ore bin 1 is provided with a first mounting hole, and the fixing seat 7 is provided with a second mounting hole. The fixing rod 6 is connected to the first mounting hole through the second mounting hole, thereby fixing the fixing rod 6.
[0027] The above setup allows the iron chain 4 to be stably suspended above the mine bin 1, providing reliable support for the protective mechanism.
[0028] Optionally, both the first mounting hole and the second mounting hole are provided with internal threads, and the lower end sidewall of the fixing rod 6 is provided with external threads. The fixing rod 6 is threadedly connected to the second mounting hole and the first mounting hole.
[0029] The above settings make installation and disassembly more convenient and faster, improving work efficiency.
[0030] Optionally, protective mechanisms are provided on both the left and right sides of the rail 3, and the rail 3 is configured in several groups, with the several groups of rail 3 evenly spaced along the surface of the liner plate 2.
[0031] The above layout can more comprehensively protect the liner 2 from damage, while improving the stability and reliability of the protective device.
[0032] Optionally, the positioning holes are configured in several groups, and the several groups of positioning holes are evenly spaced along the vertical height of the rail 3.
[0033] The above arrangement allows the iron chain 4 to be evenly distributed along the length of the rail 3, enhancing the stability and load-bearing capacity of the protective mechanism and ensuring the protective effect.
[0034] Optionally, the cross-section of the positioning hole is set to a circular structure, or the cross-section of the positioning hole is set to a rectangular structure.
[0035] The flexibility allows the positioning holes to accommodate bolts of different shapes and sizes, improving the versatility and adaptability of the protective device.
[0036] This application protects the lining plate 2 inside the ore bin 1 through a protective mechanism. The protective mechanism consists of a fixing device, a steel rail 3, and an iron chain 4. The iron chain 4 is fixedly connected to the steel rail 3 through positioning holes and through holes. At the same time, the upper end of the iron chain 4 is fixedly connected to the upper end of the ore bin 1 through the fixing device. When the material inside the ore bin 1 falls, the protective mechanism can absorb and disperse the impact force to prevent the lining plate 2 from being damaged by direct impact.
[0037] In the process of using this application, firstly, a liner plate 2 is installed on the inner surface of the ore bin 1 to ensure that the liner plate 2 is flat and firm. According to the size and shape of the liner plate 2, several sets of steel rails 3 are evenly spaced on the surface of the liner plate 2. Positioning holes are opened on the steel rails 3, and the iron chain 4 is fixed to the steel rails 3 with bolts 5 through the through holes and positioning holes. A first mounting hole is opened at the upper end of the ore bin 1, and a second mounting hole is opened on the fixing seat 7. The fixing rod 6 is connected to the first mounting hole through the second mounting hole to fix the fixing rod 6. Then, the upper end of the iron chain 4 is sleeved on the fixing rod 6 to ensure that the iron chain 4 is stably suspended at the upper end of the ore bin 1. When the material in the ore bin 1 falls, the protective mechanism will absorb and disperse the impact force to protect the liner plate 2 from damage.
[0038] This application provides effective protection for the liner 2 inside the mine bin 1 by setting up a protective mechanism. In mine operations, the impact force generated when materials fall often damages the liner 2. The protective mechanism can absorb and disperse this impact force, thereby significantly extending the service life of the liner 2. Damage to the liner 2 leads to instability in the mine structure, which in turn threatens the safety of the workers. This device effectively protects the liner 2, reduces the safety risks caused by damage to the liner 2, and improves the overall safety of mine operations.
[0039] The protective mechanism of this device is designed as a detachable structure. Components such as the fixing device, rail 3 and chain 4 can be disassembled and installed with simple operations, which makes it convenient and quick to operate when the liner 2 needs to be inspected, repaired or replaced, reducing maintenance costs and time.
[0040] This application has a reasonable structure and simple construction. It only requires reinforcement of the load-bearing parts of the foundation above the chute using high-strength anchor bolts 5. The on-site construction period is short and the operation is highly operable. The installation is simple, consisting of multiple sub-components that are detachable and do not require on-site welding. This avoids the shortcomings of welded joints in terms of poor impact and vibration resistance. If the device is severely deformed or worn due to impact, it can be directly replaced. The replacement time is extremely short, which can greatly shorten the maintenance time of the chute. The cost is low, and the materials used are mainly recyclable steel rails 3 and iron chains 4 from the mining production process. This reinforcement method is economically appropriate.
[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
