Description

Technical Field

[0001] This utility model relates to the field of aerial passenger transport devices, and in particular to an aerial passenger transport device with protective functions. Background Technology

[0002] The overhead passenger transport equipment is mainly used for transporting personnel in inclined and horizontal mine shafts. It uses an electric motor to drive the friction wheel on the reducer as the driving device, and an overhead circulating steel wire rope as the traction load. The cable grip connects the passenger chair to the steel wire rope and makes it circulate, thereby achieving the purpose of transporting personnel.

[0003] Chinese invention patent publication number CN111516710B discloses a single-sided elevated passenger vehicle, including two drive units and a steel wire rope disposed between the two drive units. Multiple grippers are mounted on the steel wire rope, and a boom is fixedly connected to the bottom of each gripper. A steering device is located at the top of one end of the boom, and a seat is mounted on top of the steering device. A gear disc is located inside the steering device, and a limiting hole is provided on the side wall of the steering device. A steering rod passes through the limiting hole, and a support plate is fixedly connected to one end of the steering rod. A limiting plate is located at one end of the support plate. This invention increases riding comfort and safety by installing a backrest and seatbelt on the seat. Handrails on both sides of the seat and footrests below facilitate getting on and off. The protective cover above the seat provides a certain degree of protection. The manually steerable seat facilitates getting on and off, and the footrests can be kicked to one side to prevent tripping when getting off. The footrests automatically return to their original position after getting off.

[0004] In related technologies, the handrails on both sides of the passenger-carrying device are at a fixed height, and the passenger is only secured and protected by the seat belt. When the passenger's height and weight are different, the height of the handrails on both sides will have a certain impact on the passenger's safety.

[0005] Therefore, it is necessary to provide an elevated passenger transport device with protective functions to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide an aerial passenger transport device with protective functions to solve the existing problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an elevated passenger transport device with protective function, comprising a base, a crossbar at the upper end of the base, a set of handrails at the left and right ends of the crossbar, a central base and two sets of side bases at the lower end of the handrails, the two sets of side bases being placed on the front and rear sides of the central base, a first inner groove being provided inside the side base, a side moving column being slidably disposed inside the first inner groove, a spring being connected to the lower end of the side moving column, the lower end of the spring being connected to the side base, and the upper end of the side moving column being fixedly connected to the lower end of the handrail.

[0008] As a further embodiment of this utility model, the interior of the base is provided with a second inner groove, and a central movable column is slidably disposed inside the second inner groove, with the upper end of the central movable column connected to the lower end of the handrail.

[0009] As a further embodiment of this utility model, a plurality of first positioning holes are provided inside one side of the central base, and a first threaded hole is provided inside one side of the central movable column. A first fixing bolt is provided inside the first positioning hole, and the central movable column can be detached and connected to the central base through the thread action between the first positioning hole and the first threaded hole via the first fixing bolt passing through the first fixing bolt.

[0010] As a further embodiment of this utility model, the upper end of the handrail is provided with a groove, and a fixing post is installed inside the groove. The front and rear ends of the fixing post are respectively fixedly connected to the handrail. The left end of the crossbar is provided with a round hole, and the left end of the crossbar can slide back and forth on the surface of the fixing post through the round hole.

[0011] As a further embodiment of this utility model, a second threaded hole is provided inside the right end of the crossbar, and multiple sets of second positioning holes are provided inside the right end of the right handrail. A second fixing bolt is installed inside the second positioning hole. The right end of the crossbar can be connected to and disassembled by the second fixing bolt passing through the thread between the second positioning hole and the second threaded hole.

[0012] This invention utilizes a first fixing bolt that passes through the threaded connection between the first positioning hole and the first threaded hole to detach and fix the central moving column and the central base. This facilitates the vertical movement of the central moving column within the second inner groove. When the central moving column moves the armrest up and down, the side moving columns on both sides will move up and down within the first inner groove. Simultaneously, the spring connected to the lower end of the side moving column generates a downward pulling force on the side moving column through elastic deformation, thereby maintaining the balance of the armrest. The crossbar can slide back and forth on the surface of the fixing column through the round hole inside the left end, thereby changing the distance between the crossbar and the base backrest. At the same time, the second fixing bolt can pass through the second positioning hole and the second threaded hole to fix the right end of the crossbar through the threaded connection, thus facilitating the protection of passengers of different heights and weights.

Detailed Implementation Example 1

[0021] like Figures 1-4 As shown, an elevated passenger transport device with protective functions includes a crossbar 2 at the upper end of a base 1, a set of handrails 3 at the left and right ends of the crossbar 2, a central base 5 and two sets of side bases 4 at the lower end of the handrails 3, with the two sets of side bases 4 placed on the front and rear sides of the central base 5. A first inner groove 8 is provided inside the side base 4, and a side moving column 6 is slidably disposed inside the first inner groove 8. A spring 9 is connected to the lower end of the side moving column 6, and the lower end of the spring 9 is connected to the side base 4. The upper end of the side moving column 6 is fixed to the lower end of the handrail 3. The connection is as follows: the interior of the middle base 5 is provided with a second inner groove 10, and the middle moving column 7 is slidably arranged inside the second inner groove 10. The upper end of the middle moving column 7 is connected to the lower end of the armrest 3. The interior of one side of the middle base 5 is provided with multiple sets of first positioning holes 12, and the interior of one side of the middle moving column 7 is provided with a first threaded hole 11. The interior of the first positioning hole 12 is provided with a first fixing bolt 13. The middle moving column 7 can be detached and connected to the middle base 5 through the thread action between the first positioning hole 12 and the first threaded hole 11 by the first fixing bolt 13 passing through the thread action between the first positioning hole 12 and the first threaded hole 11.

[0022] When the height of the handrail 3 needs to be adjusted, the first fixing bolt 13 is manually turned. The first fixing bolt 13 will engage with the first threaded hole 11, thereby removing the first fixing bolt 13 from the inside of the first threaded hole 11. At this time, the handrail 3 is pulled up and down. When the handrail 3 moves up and down, the middle moving column 7 connected to the lower end will slide up and down inside the second inner groove 10. After the height of the handrail 3 is adjusted, the first fixing bolt 13 is passed through the first positioning hole 12 and engaged with the first threaded hole 11 to fix the middle moving column 7 and the middle base 5. At the same time, when the middle moving column 7 slides up and down, the two sets of side moving columns 6 slide up and down inside the first inner groove 8. The springs 9 connected to the lower ends of the two sets of side moving columns 6 will undergo elastic deformation, thereby balancing the two ends of the handrail 3 to a certain extent and preventing the front and rear ends of the handrail 3 from tilting. Example 2

[0023] like Figures 5-6 As shown, the upper end of the handrail 3 has a groove 14 inside, and a fixing post 15 is installed inside the groove 14. The front and rear ends of the fixing post 15 are fixedly connected to the handrail 3 respectively. The left end of the crossbar 2 has a round hole inside, and the left end of the crossbar 2 can slide back and forth on the surface of the fixing post 15 through the round hole. The right end of the crossbar 2 has a second threaded hole 16 inside, and the right end of the right handrail 3 has multiple sets of second positioning holes 17 inside. The second fixing bolt 18 is installed inside the second positioning hole 17. The right end of the crossbar 2 can be disassembled and connected to the handrail 3 through the thread action between the second positioning hole 17 and the second threaded hole 16 via the second fixing bolt 18 passing through the second fixing bolt 18.

[0024] In use, when it is necessary to adjust the distance between the crossbar 2 and the backrest of the base 1, the second fixing bolt 18 is manually turned. The second fixing bolt 18 will engage with the second threaded hole 16 through the threading action. Through this threading action, the second fixing bolt 18 will be disassembled from the inside of the second threaded hole 16. At this time, the crossbar 2 is pulled, and the crossbar 2 can slide back and forth on the surface of the fixing column 15 through the round hole provided inside the left end, thereby moving the fixing column 15 back and forth. When the crossbar 2 is moved to the appropriate position, the second fixing bolt 18 is passed through the second positioning hole 17 and aligned with the second threaded hole 16. The second fixing bolt 18 is then manually turned, and the second fixing bolt 18 will engage with the second threaded hole 16 through the threading action, thereby fixing the crossbar 2 and the handrail 3 in place, thus securing the crossbar 2 in the appropriate position and providing protection for passengers.

[0025] Working principle: During use, when the height of the handrail 3 needs to be adjusted, the first fixing bolt 13 is manually turned. The first fixing bolt 13 will engage with the first threaded hole 11, thereby removing the first fixing bolt 13 from the inside of the first threaded hole 11. At this time, the handrail 3 is pulled up and down. When the handrail 3 moves up and down, the middle moving column 7 connected to the lower end will slide up and down inside the second inner groove 10. After the height of the handrail 3 is adjusted, the first fixing bolt 13 is passed through the first positioning hole 12 and engaged with the first threaded hole 11 to fix the middle moving column 7 and the middle base 5. At the same time, when the middle moving column 7 slides up and down, the two sets of side moving columns 6 slide up and down inside the first inner groove 8. The springs 9 connected to the lower ends of the two sets of side moving columns 6 will undergo elastic deformation, thereby balancing the two ends of the handrail 3 to a certain extent and avoiding... The front and rear ends of the handrail 3 are tilted. When it is necessary to adjust the distance between the crossbar 2 and the backrest of the base 1, the second fixing bolt 18 is manually turned. The second fixing bolt 18 will engage with the second threaded hole 16. Through this threading action, the second fixing bolt 18 will be disassembled from the inside of the second threaded hole 16. At this time, the crossbar 2 is pulled. The crossbar 2 can slide back and forth on the surface of the fixing column 15 through the round hole set inside the left end, thereby moving the fixing column 15 back and forth. When the crossbar 2 is moved to the appropriate position, the second fixing bolt 18 is passed through the second positioning hole 17 and aligned with the second threaded hole 16. The second fixing bolt 18 is then manually turned. The second fixing bolt 18 will engage with the second threaded hole 16, thereby fixing the crossbar 2 and the handrail 3. This ensures that the crossbar 2 is fixed in the appropriate position, providing protection for passengers.
