Description

Technical Field

[0001] This application relates to the field of underground lifting equipment technology, and more specifically, to a suspended lifting system. Background Technology

[0002] As a key piece of equipment for the installation and retraction of machinery in fully mechanized coal mining faces, the movement performance of underground cranes directly affects the efficiency of underground operations. Currently, heavy equipment handling underground mainly employs two movement methods: tracked cranes and rail-mounted cranes. Tracked cranes move by hydraulically driving tracks, featuring low ground pressure and high traction, but they are prone to slippage in steeply inclined roadways, and the complex hydraulic drive system increases the equipment failure rate. Rail-mounted cranes rely on pre-laid rails for guidance and movement. While this method offers precise positioning, it requires significant time for ground leveling and rail laying. Especially at mining faces, changes in geological conditions and material transportation can easily cause rail deformation or burial, necessitating frequent work interruptions for rail maintenance, severely impacting the continuity of mine production.

[0003] Therefore, there is an urgent need to provide a suspended lifting system to solve the problems existing in the prior art. Utility Model Content

[0017] Analysis shows that the invention of laying the first and second gear mechanisms on the roof of the tunnel in this application will not be affected by the operation of other equipment during system operation.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] like Figures 1-5 As shown, the suspended lifting system provided in this application includes a first gear mechanism 1 and a second gear mechanism 10. The first gear mechanism 1 and the second gear mechanism 10 are fixed parallel to each other on the roof of the tunnel. A first lifting mechanism 2 is installed on the first gear mechanism 1 and is slidably connected to the first gear mechanism 1. A second lifting mechanism 3 is installed on the second gear mechanism 10 and is slidably connected to the second gear mechanism 10. The first lifting mechanism 2 and the second lifting mechanism 3 are arranged opposite to each other. Both the first lifting mechanism 2 and the second lifting mechanism 3 include a power component. Both the first gear mechanism 1 and the second gear mechanism 10 include a gear 101. The power component includes a drive wheel 209 and a drive member. The drive wheel 209 meshes with the gear 101, and the drive member drives the drive wheel 209 to rotate.

[0031] Compared with existing technologies, the suspended lifting system provided in this application has the following advantages:

[0032] The suspended lifting system provided in this application innovatively lays the first gear mechanism 1 and the second gear mechanism 10 on the roof of the tunnel. When the system is running, the lifting units can be flexibly matched and are easy to use, and will not interfere with the operation of the monorail or other transportation equipment.

[0033] By laying two parallel first gear mechanism 1 and second gear mechanism 10, a first lifting mechanism 2 and a second lifting mechanism 3 can be installed on the first gear mechanism 1 and the second gear mechanism 10, so that the lifting and transfer of equipment can be realized through the relatively arranged first lifting mechanism 2 and second lifting mechanism 3.

[0034] Specifically, since both the first lifting mechanism 2 and the second lifting mechanism 3 in this application include a power component, and the power component includes a drive wheel 209 and a drive member, the drive wheel 209 meshes with the gear rail 101, and the drive member can drive the drive wheel 209 to rotate, thereby enabling the first lifting mechanism 2 and the second lifting mechanism 3 to operate on the first gear rail mechanism 1 and the second gear rail mechanism 10. Therefore, the first lifting mechanism 2 and the second lifting mechanism 3 can lift the equipment and realize the transfer of the equipment through movement on the first gear rail mechanism 1 and the second gear rail mechanism 10.

[0035] In this application, multiple first lifting mechanisms 2 and second lifting mechanisms 3 can be provided. For example, two, three or even more first lifting mechanisms 2 can be provided on the first gear mechanism 1. Correspondingly, the number of second lifting mechanisms 3 needs to correspond to the number of first lifting mechanisms 2 to ensure the stability of the lifting process. The position can be adjusted according to the specific lifting connection point. Usually, the first lifting mechanisms 2 and second lifting mechanisms 3 are set opposite each other to ensure that the lifting connection point positions correspond, thereby ensuring uniform force. However, when the number of lifting mechanisms increases, they can also be lifted in a staggered manner. No restrictions are imposed here.

[0036] Optionally, such as Figures 1-5 As shown, the first gear mechanism 1 and the second gear mechanism 10 in this application also include a plurality of positioning seats 102 and positioning elements. The positioning seat 102 includes a mounting part 1021 and a connecting part 1022. The mounting part 1021 is attached to the top plate of the roadway, and a plurality of positioning holes are formed on the mounting part 1021. The positioning elements pass through the positioning holes to fix the mounting part 1021 to the top plate. One end of the connecting part 1022 is connected to the mounting part 1021, and the other end is connected to the gear 101. The gear 101 is perpendicular to the connecting part 1022 and parallel to the mounting part 1021.

[0037] In this application, the installation part 1021 is attached to the roof of the tunnel, and multiple positioning holes are formed on the positioning part. The positioning element passes through the positioning holes to firmly fix the installation part 1021 to the roof, ensuring the stability of the positioning seat 102. In the laying direction of the toothed rail 101, there are multiple positioning seats 102. In this application, the toothed rail 101 is formed by multi-segment splicing. Each segment of the toothed rail 101 is connected to at least two positioning seats 102 to ensure the connection stability of the toothed rail 101. At the same time, it can also ensure that the positioning seat 102 can bear the weight of the support and other equipment after installation.

[0038] Accordingly, this application installs a connecting part 1022 on the mounting part 1021. The connecting part 1022 in this application can be integrally formed with the mounting part 1021 or formed by welding. The connecting part 1022 enables the connection between the gear rail 101 and the mounting part 1021, thereby achieving a fixed connection between the gear rail 101 and the top plate.

[0039] It should be noted that the gear rail 101 in this application is in a horizontal state after installation. Therefore, the axis of the drive wheel 209 in this application is perpendicular to the gear rail 101 and is also arranged in a horizontal direction. The drive wheel 209 in this application is a gear. Through the meshing of the gear and the gear rail 101, the first lifting mechanism 2 and the second lifting mechanism 3 can achieve stable movement on the gear rail 101. After being in place, the meshing of the gear rail 101 and the gear can ensure the fixation of the position to a certain extent.

[0040] The driving component in this application can be an electric motor, but a hydraulic motor is preferred. A hydraulic motor can provide stronger power to drive the overall mechanism to move on the gear rail 101 or in a hoisting state.

[0041] Optionally, such as Figure 1 Combination Figure 2 As shown, the suspended lifting system provided in this application further includes a third lifting mechanism 4, a fourth lifting mechanism 5, a first connecting member 8, and a second connecting member 9; the third lifting mechanism 4 is slidably mounted on the first gear mechanism 1, the fourth lifting mechanism 5 is slidably mounted on the second gear mechanism 10, and the two ends of the first connecting member 8 are respectively connected to the first lifting mechanism 2 and the third lifting mechanism 4, and the two ends of the second connecting member 9 are respectively connected to the second lifting mechanism 3 and the fourth lifting mechanism 5.

[0042] In this application, a third lifting mechanism 4 may be further installed on the first gear mechanism 1, and a fourth lifting mechanism 5 may be further installed on the second gear mechanism 10. Since the stability of lifting is poor when using only a first lifting mechanism 2 and a second lifting mechanism 3, this application can ensure the stability of the lifting and transportation process by further adding a third lifting mechanism 4 and a fourth lifting mechanism 5.

[0043] The third lifting mechanism 4 and the fourth lifting mechanism 5 further installed in this application do not have the power components installed in the first lifting mechanism 2 and the second lifting mechanism 3. Therefore, by connecting the first connecting member 8 between the first lifting mechanism 2 and the third lifting mechanism 4, and connecting the second lifting mechanism 3 and the fourth lifting mechanism 5 between the second lifting mechanism 3 and the fourth lifting mechanism 5, this application can realize the synchronous movement of the first lifting mechanism 2 and the third lifting mechanism 4, and the synchronous movement of the second lifting mechanism 3 and the fourth lifting mechanism 5, which greatly saves space occupation and energy consumption.

[0044] Therefore, as Figures 1-5 As shown, in the first lifting assembly and first mounting platform 201 of the first lifting mechanism 2 and the second lifting mechanism 3 in this application, the first mounting platform 201 includes a first mounting part 2011 and a second mounting part 2012. The power assembly is mounted on the first mounting part 2011, and the axis of the drive wheel 209 is perpendicular to the mounting platform. The first lifting assembly is mounted on the second mounting part 2012, and the second mounting part 2012 has a first hollow hole. The lifting hook 204 of the first lifting assembly passes through the first mounting platform 201 through the first hollow hole.

[0045] Since the first mounting platform 201 needs to provide a mounting base for the power assembly, the first mounting platform 201 has a larger area. The power assembly can be installed through the first mounting part 2011, while the first lifting assembly can be installed through the second mounting part 2012.

[0046] Since the first lifting assembly is required for lifting, the second mounting part 2012 has a first hollow hole to allow the lifting hook 204 and lifting chain 203 to pass through smoothly.

[0047] Accordingly, such as Figure 1 Combination Figure 2 As shown, the third lifting mechanism 4 and the fourth lifting mechanism 5 in this application also include a second lifting assembly and a second mounting platform. The second lifting assembly is disposed on the second mounting platform, and the second mounting platform has a second hollow hole. The lifting hook 204 of the second lifting assembly passes through the second hollow hole and passes through the second mounting platform.

[0048] Since the third lifting mechanism 4 and the fourth lifting mechanism 5 in this application do not require the installation of a power component, the second mounting platform can be designed with a smaller area, only capable of supporting the second lifting assembly. Since the first lifting assembly and the second lifting assembly in this application have the same structure, a second hollow hole is opened on the second mounting platform to allow the lifting chain 203 and the lifting hook 204 in the second lifting assembly to pass smoothly.

[0049] Optionally, such as Figures 1-5 As shown, the first and second lifting assemblies in this application both include a lifting drive 202, a pulley 205, and a lifting chain 203; the lifting drive 202 is installed on both the first mounting platform 201 and the second mounting platform, one end of the lifting chain 203 is connected to the lifting drive 202, and the other end passes around the pulley 205 and is connected to the lifting hook 204, and the pulley 205 is rotatably connected to the first mounting platform 201 and the second mounting platform.

[0050] The lifting drive 202 can be a hydraulic hoist, emulsion hoist, electric hoist, or pneumatic hoist, etc. The above structure is used to realize the winding and releasing of the lifting chain 203, thereby realizing the raising and lowering of the lifting hook 204. The pulley 205 can support the lifting chain 203, ensuring the smooth winding and releasing process of the lifting chain 203.

[0051] Optionally, such as Figures 1-5 As shown, the first lifting assembly and the second lifting assembly in this application also include an adjusting member 208 and a connecting rod 207. The adjusting member 208 of the first lifting assembly is mounted on the first mounting platform 201, and the adjusting member 208 of the second lifting assembly is mounted on the second mounting platform. The telescopic end of the adjusting member 208 can move towards or away from the gear rail 101, and one end of the connecting rod 207 is connected to the telescopic end of the adjusting member 208. The pulley 205 is rotatably connected to the other end of the connecting rod 207.

[0052] Since the first lifting mechanism 2 and the second lifting mechanism 3 are arranged opposite each other in this application, and the third lifting mechanism 4 and the fourth lifting mechanism 5 are arranged opposite each other, and the lifting positions of different transfer equipment may be different, but the distance between the two parallel toothed rails 101 in this application is fixed and cannot be adjusted, this application further provides an adjusting member 208, and connects the telescopic end of the adjusting member 208 to one end of the connecting rod 207, and the other end of the connecting rod 207 to the pulley 205. Thus, by adjusting the telescopic extension of the adjusting member 208, the connecting rod 207 can be moved towards or away from the toothed rail 101, and the lifting hook 204 can be moved towards or away from the toothed rail 101.

[0053] Therefore, when the size of the equipment to be transferred changes, the distance between the lifting hooks 204 of the first lifting mechanism 2 and the second lifting mechanism 3, as well as the distance between the lifting hooks 204 of the third lifting mechanism 4 and the fourth lifting mechanism 5, can be adjusted to adapt to the connection point position of different transfer equipment, thereby improving the overall system's adaptability.

[0054] Optionally, such as Figures 1-5 As shown, the first lifting assembly and the second lifting assembly in this application also include a sliding seat 2051 and a track box 206; the track box 206 is provided with a slide rail, the sliding seat 2051 has a slider formed at the position corresponding to the slide rail, the slider is slidably connected to the slide rail, and the track box 206 has a groove parallel to the slide rail at the position corresponding to the connecting rod 207, the connecting rod 207 passes through the groove and is connected to the sliding seat 2051.

[0055] To ensure the stability of the adjustment process and the connection, this application further provides a sliding seat 2051 and a track box 206. Track boxes 206 are provided on both the first mounting platform 201 and the second mounting platform. The track box 206 can protect the lifting chain 203 and the lifting hook 204 from movement and prevent debris falling from the top plate from entering the gap and causing the structure to jam. On the other hand, the track box 206 can also support the sliding seat 2051, making the sliding process of the sliding seat 2051 more stable. Accordingly, the track box 206 in this application is provided with a slide rail, and the sliding seat 2051 is provided with a slider at the position corresponding to the slide rail, so that the sliding seat 2051 can reciprocate in the extension direction of the slide rail, and the extension direction of the slide rail is consistent with the extension and retraction direction of the adjustment component 208.

[0056] Of course, in this application, the connecting rod 207 is connected to the sliding seat 2051, and the track box 206 is provided with a groove corresponding to the position of the connecting rod 207. The groove can limit and guide the connecting rod 207 to a certain extent, thereby ensuring the stability of the moving process of the adjusting component 208 driving the sliding seat 2051.

[0057] It should be noted that the adjusting component 208 in this application is a hydraulic cylinder, which can provide a more stable driving force and ensure the smooth adjustment of the lifting hook 204.

[0058] Optionally, such as Figures 3-5As shown, the suspended lifting device provided in this application further includes a limiting mechanism, which includes a first limiting component and a second limiting component. The first limiting component includes a first positioning seat 210, a second positioning seat 211, a first connecting shaft 213, a second connecting shaft 214, a third connecting shaft 215, a first traveling wheel 216, a second traveling wheel 217, and a first limiting wheel 218. The first mounting platform 201 and the second mounting platform are each provided with a first positioning seat 210 and a second positioning seat 211, and the first positioning seat 210 and the second positioning seat 211 are arranged opposite to each other on both sides of the gear rail 101. One end of the first connecting shaft 213 is connected to the first positioning seat 210, and the other end is connected to the first traveling wheel 216. One end of the second connecting shaft 214 is connected to the second positioning seat 211, and the other end is connected to the second traveling wheel 217, and the first traveling wheel 216 and the second traveling wheel 217 are spaced apart. The two ends of the third connecting shaft 215... The first positioning seat 212 is connected to the first positioning seat 210 and the second positioning seat 211 respectively, and is located below the first connecting shaft 213 and the second connecting shaft 214. The first limiting wheel 218 is rotatably connected to the third connecting shaft 215, and the first limiting wheel 218, the first traveling wheel 216 and the second traveling wheel 217 form a limiting space. The toothed rail 101 passes through the limiting space, and the upper surface of the toothed rail 101 faces the first traveling wheel 216 and the second traveling wheel 217, and the lower surface faces the first limiting wheel 218. The second limiting component includes a third positioning seat 212, a fourth connecting shaft 219 and a second limiting wheel 220. The third positioning seat 212 is provided on the first mounting platform 201 and the second mounting platform at the position corresponding to the upper toothed rail 101. One end of the fourth connecting shaft 219 is connected to the third positioning seat 212, and the other end is connected to the second limiting wheel 220. The second limiting wheel 220 abuts against the side wall of the toothed rail 101.

[0059] Since the first traveling wheel 216 and the second traveling wheel 217 in this application are respectively arranged on the upper surface of the toothed rail 101, and the upper surface is connected to the connecting part 1022, by arranging the first traveling wheel 216 and the second traveling wheel 217 at intervals, the connecting part 1022 can pass smoothly, thereby ensuring the smooth movement of the overall structure along the direction of the toothed rail 101.

[0060] Correspondingly, the first limiting wheel 218, which is set on the lower surface of the toothed rail 101, can cooperate with the first traveling wheel 216 and the second traveling wheel 217 to form a limiting space, clamping the toothed rail 101 in the limiting space, thereby achieving vertical limiting of the overall structure.

[0061] Furthermore, by further configuring a second limiting wheel 220, which abuts against the side wall of the gear rail 101, the overall structure can be further limited.

[0062] Preferably, in this application, the second limiting wheel 220 has a dumbbell-shaped double wheel structure, with the middle position abutting against the side wall of the gear rail 101, thereby utilizing the hourglass-shaped second limiting wheel 220 to a certain extent to ensure vertical stability.

[0063] It should be noted that there are multiple second limiting wheels 220 in this application, and preferably two, located on the same side of the gear rail 101, to ensure the operational stability of the overall structure.

[0064] Optionally, such as Figure 1 Combination Figure 2 As shown, the suspended lifting system provided in this application also includes a fifth lifting mechanism 6, a sixth lifting mechanism 7, a third connecting member, and a fourth connecting member. The fifth lifting mechanism 6 is slidably mounted on the first gear mechanism 1, the sixth lifting mechanism 7 is slidably mounted on the second gear mechanism 10, the two ends of the third connecting member are respectively connected to the third lifting mechanism 4 and the fifth lifting mechanism 6, and the two ends of the fourth connecting member are respectively connected to the fourth lifting mechanism 5 and the sixth lifting mechanism 7.

[0065] Since the drive components and adjustment components 208 mentioned above in this application all require hydraulic oil to achieve power output, and the lifting system in this application is arranged on the roof of the tunnel, while the pump station is usually located on the ground, this application further provides a fifth lifting mechanism 6 and a sixth lifting mechanism 7. Preferably, both the fifth lifting mechanism 6 and the sixth lifting mechanism 7 in this application are equipped with valve groups and electrical control boxes, so that the pump station and electricity on the ground can be introduced into the fifth lifting mechanism 6 and the sixth lifting mechanism 7 through oil pipes and wires. Then, the fifth lifting mechanism 6 and the sixth lifting mechanism 7 distribute the power to the first lifting mechanism 2, the second lifting mechanism 3, the third lifting mechanism 4 and the fourth lifting mechanism 5 as needed, so as to ensure the stable operation of the overall system.

[0066] It should be noted that the pump station mentioned above in this application can also be installed on the mounting platform, and the valve group and electrical control box are not limited to being installed on the mounting platforms of the fifth lifting mechanism 6 and the sixth lifting mechanism 7. They can also be installed in other lifting mechanisms or a separate independent lifting mechanism can be set up solely for the installation of the valve group, electrical control box and pump station.

[0067] It is understood that the fifth lifting mechanism 6 and the sixth lifting mechanism 7 in this application are closer to the pump station on the ground. Therefore, the valve group and electrical control box mentioned above are set in the fifth lifting mechanism 6 and the sixth lifting mechanism 7. The fifth lifting mechanism 6 and the sixth lifting mechanism 7 also have the structure of the lifting hook 204, lifting chain 203 and winch mentioned above, thus also having lifting capacity, improving the flexibility of the overall system and increasing the lifting weight.

[0068] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
