Description

Technical Field

[0001] The utility model relates to the technical field of screw elevators, and specifically relates to a maintenance platform for a screw elevator. Background Technique

[0002] A screw elevator is a device that conveys materials through a sliding conveying track composed of roller shafts. It plays an important role in industrial production and is widely used in various fields.

[0003] The background of the screw elevator can be traced back to the Industrial Revolution. With the continuous development of industrial production, the demand for material conveying has been increasing day by day. Traditional conveying methods such as belt conveyors and scraper conveyors have some limitations, such as limited conveying distance, low conveying efficiency, and high maintenance costs. In order to meet the requirements of industrial production for efficient, reliable, and energy-saving material conveying, the screw elevator came into being.

[0004] The roller shaft of the screw elevator is one of its core components, and its design directly affects the performance and service life of the equipment. The roller shaft is usually made of high-strength and wear-resistant materials such as alloy steel and stainless steel to ensure that it can withstand the impact and wear of materials during long-term operation. Secondly, the sliding conveying track of the screw elevator is composed of a series of roller shafts, and its design directly affects the conveying efficiency and stability of the equipment. The sliding conveying track usually adopts an inclined design to ensure that the materials can slide smoothly under the action of gravity. The driving device of the screw elevator is its power source, and its design directly affects the operation efficiency and reliability of the equipment. The driving device usually consists of equipment such as motors and reducers to ensure that the equipment can operate stably under different working conditions. In addition, the control system of the screw elevator is the embodiment of its intelligence, and its design directly affects the operation efficiency and safety of the equipment. The control system usually consists of equipment such as PLCs and touch screens to achieve the automatic control and remote monitoring of the equipment.

[0005] In short, a screw elevator is a device that conveys materials through a sliding conveying track composed of roller shafts. It has the advantages of high conveying efficiency, long conveying distance, and low maintenance cost, and is widely used in various fields. With the continuous development of technology, the technology of the screw elevator is also constantly innovating and improving to meet the requirements of industrial production for efficient, reliable, and energy-saving material conveying.

[0006] The existing maintenance platforms for screw elevators generally aim to improve the existing screw elevators that cannot meet the requirements of different environments in terms of lifting height, resulting in the inability to meet the industrial production needs in actual applications. For example, the screw elevator disclosed in the Chinese patent with the publication number CN208761521U can achieve the axial telescopic movement of the screw conveyor track along the support column through the cooperation of structures such as support columns, screw conveyor tracks, drive rods, chain plate drive devices, sliding grooves, chain tensioning mechanisms, linear motors, guardrails, sliding tracks, power sources, first chains, drive wheels, inlet ends, outlet ends, tensioning wheels, second chains, first reversing wheels, third chains, second reversing wheels, stators, rotors, outer guardrails, and inner guardrails, so as to achieve the effect that the lifting height of the screw elevator can be freely adjusted.

[0007] However, during the material conveying process of the screw elevator maintenance platform in the above cited document, the situation of material jamming often occurs. This may be caused by reasons such as the viscosity, humidity, or irregular shape of the material. When the material jams, the chain will be subject to additional resistance, which may lead to damage to the conveying equipment, such as chain bending, chain breakage, or motor overload. Therefore, maintenance personnel need to carry out repairs in a timely manner. When maintenance personnel need to repair the screw elevator, due to the lack of a special maintenance platform, they need to climb the equipment with repair tools. This is not only inconvenient but also poses a certain safety risk. Maintenance personnel need to work at heights without sufficient support and protection, which increases the possibility of them slipping or getting injured from the equipment. In addition, since screw elevators are usually installed in relatively narrow spaces, maintenance personnel may be restricted by the space during maintenance and it is difficult to move freely. They may need to operate in a narrow space, which increases the difficulty and time of maintenance. Moreover, the lack of a maintenance platform may also lead to unstable placement of repair tools and parts, increasing the risk of tool dropping and part loss. This will not only affect the maintenance efficiency but also pose a safety hazard to maintenance personnel and the surrounding environment.

[0008] In summary, there are some serious problems in the current maintenance of screw elevators. These problems not only affect the normal operation of the equipment but also pose a threat to the safety of maintenance personnel. Therefore, it is necessary to improve the screw elevator to solve these problems. Utility Model Content

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a screw elevator maintenance platform, including a screw elevator 1, and a retractable maintenance platform 200 is installed on the screw elevator 1;

[0033] Through the mutual cooperation of the retractable maintenance platforms 200 on the screw elevator 1, when the screw elevator 1 needs to be repaired, the maintenance personnel do not need to climb the equipment, but can repair through the specially designed retractable maintenance platform 200. This is not only convenient and fast, but also greatly reduces the work intensity and safety risks of the maintenance personnel, provides sufficient support and protection, enables the maintenance personnel to work safely at high altitudes. Its stable structure and reliable protective measures effectively reduce the possibility of the maintenance personnel slipping or being injured from the equipment, and can perform maintenance operations freely without space restrictions, improving the maintenance efficiency and safety.

[0034] In this embodiment, when the retractable maintenance platform 200 repairs the screw elevator 1, the maintenance personnel do not need to climb the equipment.

[0035] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the retractable maintenance platform 200 includes an installation connection component installed on the side of the screw hoist 1 close to the ground and a maintenance table component slidably connected within the installation connection component. Four auxiliary sliding components are evenly distributed and installed on the installation connection component. The maintenance table component is slidably connected between the opposite sides of the four auxiliary sliding components. An auxiliary stability component is installed between one side of the maintenance table component and the installation connection component. Two support plates 206 are installed on the side of the installation connection component close to the ground and are mirror-symmetrical.

[0036] A connection groove 207 is formed on one side of the support plate 206.

[0037] The retractable maintenance platform 200 further includes a support rod member 208 fixedly connected to the inner side wall of the connection groove 207. Two stable support components, which are connected to the support rod member 208 and are mirror-symmetrically distributed, are installed on the side of the maintenance table component close to the ground. A safety protection component is installed on the screw hoist 1.

[0038] It should be noted that the installation connection component includes a first fixing plate 2011, an installation column 2012, and a second fixing plate 2013. One side of the first fixing plate 2011 is fixedly installed on the side of the screw hoist 1 close to the ground through bolts. One end of the installation column 2012 is fixedly connected to the side of the first fixing plate 2011 close to the ground, and the opposite end is fixedly connected to the second fixing plate 2013. The number of installation columns 2012 is multiple and they are evenly distributed to stably support the telescopic movement of the maintenance table component.

[0039] It can be understood that the maintenance table component includes a maintenance table 2021 and a handle 2022. Convex grooves 203 are formed on both sides of the maintenance table 2021. One side of the handle 2022 is fixedly connected to one side of the maintenance table 2021. The convex groove 203 is slidably connected to two corresponding auxiliary sliding components on the same side, so that the maintenance table 2021 can move between the opposite sides of the first fixing plate 2011 and the second fixing plate 2013 when the handle 2022 is pulled.

[0040] In addition, the auxiliary sliding component includes a connection block 2041, a rotating rod member 2042, and a pulley 2043. The two sides of the connection block 2041 are respectively fixedly installed between the opposite sides of the first fixing plate 2011 and the second fixing plate 2013 through bolts. One end of the rotating rod member 2042 is rotatably connected to the inside of the connection block 2041 through a bearing, and the opposite end is rotatably connected to the inside of the pulley 2043 through a bearing. The outside of the pulley 2043 is slidably connected to the inside of the convex groove 203 and fits for sliding, so as to stably support the movement of the maintenance table 2021.

[0041] In this embodiment, the auxiliary stabilizing component includes a convex sliding block 2051 and a slide rail 2052. One side of the convex sliding block 2051 is fixedly connected to the side of the maintenance table 2021 close to the ground. A slide rail 2052 that is slidably connected to the convex sliding block 2051 is fixedly connected to the side of the second fixing plate 2013 close to the first fixing plate 2011, so as to further improve the stability of the movement of the maintenance table 2021.

[0042] It should also be noted that the stable support component includes a hinge seat 2091 and a configuration support rod 2092. The hinge seat 2091 is fixedly connected to the side of the maintenance table 2021 close to the ground. One end of the configuration support rod 2092 is arc-shaped and the other end is hook-shaped. The configuration support rod 2092 with one end being arc-shaped is hinged to the hinge seat 2091 through a pin shaft. The configuration support rod 2092 with one end being hook-shaped is hooked on the outer side of the support rod member 208. After the maintenance table 2021 is pulled out, the configuration support rod 2092 will extend into the connection groove 207 and use its hook-shaped end to hook the support rod member 208. In this way, under the strong support of the configuration support rod 2092, the maintenance table 2021 can be stably supported, fully considering the stability requirements of the maintenance table 2021 during use. Through the mutual cooperation of the hinge seat 2091 and the configuration support rod 2092, the maintenance table 2021 can remain stable after being pulled out, providing a safe and reliable working platform for maintenance personnel.

[0043] In addition, the safety protection component includes a protective fence 2101 and a safety rope hook 2102. Both ends of the protective fence 2101 are fixedly installed on one side of the screw hoist 1 through bolts, and one side of the safety rope hook 2102 is fixedly installed on one side of the protective fence 2101 through bolts, so as to provide safety protection for maintenance personnel.

[0044] The working principle of the above embodiment is as follows:

[0045] When maintenance is required for the spiral elevator 1, the maintenance personnel first pull the handle 2022 to extend the maintenance platform 2021 outwards from the installation connection assembly. During this process, the convex grooves 203 on both sides of the maintenance platform 2021 interact with the pulleys 2043 of the auxiliary sliding assembly. When the maintenance platform 2021 extends outwards, the pulleys 2043 roll within the convex grooves 203, and at the same time, the rotating rod 2042 rotates within the connecting block 2041, thus realizing the stable movement of the maintenance platform 2021. As the maintenance platform 2021 extends, the convex sliding block 2051 of the auxiliary stability assembly slides on the slide rail 2052. The convex sliding block 2051 is fixedly connected to the side of the maintenance platform 2021 close to the ground, and the slide rail 2052 is fixedly connected to the side of the second fixing plate 2013 close to the first fixing plate 2011. The cooperation between the convex sliding block 2051 and the slide rail 2052 further improves the stability of the movement of the maintenance platform 2021, preventing the maintenance platform 2021 from shaking or tilting during movement. When the maintenance platform 2021 is fully extended, the hinge seat 2091 and the configuration support rod 2092 of the stable support assembly start to play a role. The hinge seat 2091 is fixedly connected to the side of the maintenance platform 2021 close to the ground. One end of the configuration support rod 2092 is hinged to the hinge seat 2091 through a pin shaft. The configuration support rod 2092 with an arc-shaped end is hinged to the hinge seat 2091 through a pin shaft, and the other end with a hook-shaped configuration support rod 2092 hooks on the outer side of the support rod 208. The hook-shaped end of the configuration support rod 2092 extends into the connection groove 207 and tightly combines with the support rod 208. In this way, under the support of the configuration support rod 2092, the maintenance platform 2021 is stably supported, ensuring that the maintenance personnel can safely carry out maintenance work on it. The maintenance personnel can stand on the maintenance platform 2021, and at the same time, the protective fence 2101 and the safety rope hook 2102 provide installation guarantees for the maintenance personnel, so as to facilitate the maintenance personnel to safely inspect, maintain, and service the spiral elevator 1. Since the maintenance platform 2021 provides sufficient space and stable support, the maintenance personnel can work more conveniently, reducing the risks and inconveniences of climbing the equipment. After the maintenance is completed, the maintenance personnel can place the maintenance tools and parts on the maintenance platform 2021, and then push the maintenance platform 2021 to make it return to the installation connection assembly. During this process, the auxiliary sliding assembly and the auxiliary stability assembly continue to play a role, ensuring that the maintenance platform 2021 can be stably retracted, completing the entire maintenance process.

[0046] Compared with the prior art: For this maintenance platform of the screw elevator, through the mutual cooperation between the retractable maintenance platform 200 on the screw elevator 1, when the screw elevator 1 needs to be maintained, maintenance personnel do not need to climb the equipment. Instead, they can perform maintenance through the specially designed retractable maintenance platform 200, which is not only convenient and fast, but also greatly reduces the working intensity and safety risks of maintenance personnel, provides sufficient support and protection, enables maintenance personnel to work safely at heights, and its stable structure and reliable protective measures effectively reduce the possibility of maintenance personnel slipping or being injured from the equipment. It can carry out maintenance operations freely without being restricted by space, improves the maintenance efficiency and safety, and solves the problems of easy jamming of materials, inconvenient maintenance, and safety risks existing in the prior maintenance platform of the screw elevator.
