[0038] The first pedestrian bridge 1 extends in a first direction, crosses the first conveyor 200 , and has a first bridge passage.

[0039] The operating platform 2 is arranged on one side of the first pedestrian crossing bridge 1 adjacent to the second conveyor 300 in the second direction. The operating platform 2 has an operating space, which is communicated with the first crossing bridge passage.

[0040] The support ladder 3 and the operating platform 2 are respectively located on both sides of the second conveyor 300 in the second direction. A box door 24 is provided on the operating platform 2. The box door 24 is located on one side of the operating platform 2 adjacent to the support ladder 3 in the second direction.

[0041] The support plate 4 is slidably disposed on the operating platform 2 along the second direction between a connection position where it can overlap the support ladder 3 and a separation position where it can separate from the support ladder 3 .

[0042] The overlapping transfer point pedestrian bridge system of the embodiment of the present invention forms a pedestrian bridge on the first conveyor 200 by setting a first pedestrian bridge 1 across the first conveyor 200, and personnel can reach the operating space of the operating platform 2 through the first pedestrian bridge 1. When it is necessary to cross the second conveyor 300, the support plate 4 can be slid out along the operating platform 2 so that the support plate 4 reaches the connection position overlapped with the support ladder 3, so that the support plate 4 and the support ladder 3 form a second pedestrian bridge with a second bridge passage, and the box door 24 is opened to connect the second bridge passage with the operating space, so that the first bridge passage is connected, and the second bridge passage and the operating space are in a connected state, so as to facilitate the passage of personnel, and facilitate personnel to get on and off the operating platform 2 and operate in the operating platform 2.

[0043] The overlapping transfer point pedestrian bridge system of the embodiment of the present invention forms a pedestrian bridge system that can connect two coal flow conveyor belts across the transfer point with the first pedestrian bridge 1, the operating platform 2, the support plate 4 and the support ladder 3. The first bridge passage formed by the first pedestrian bridge 1 spans the first conveyor 200, the second bridge passage formed by the support plate 4 and the support ladder 3 spans the second conveyor 300, and the operating space of the operating platform 2 connects the first bridge passage and the second bridge passage. People can cross the first conveyor 200 through the first pedestrian bridge 1, and can also enter the operating platform 2 through the first pedestrian bridge 1, and can also cross the second conveyor 300 through the operating platform 2 and the support plate 4, so that the walking route formed by people is more reasonable.

[0044] The overlapping transfer point pedestrian bridge system of the embodiment of the present invention not only eliminates the steps required for the upper and lower operating platforms 2 and the space occupied by the steps, but also makes the layout of the operating platform 2, the first pedestrian bridge 1 and the support plate 4 at the transfer point more reasonable, thereby achieving the purpose of saving space and forming a reasonable movement line.

[0045] In order to make the overlapping transfer point pedestrian crossing system of the embodiment of the present invention easier to understand, Figures 1 to 6 Take this as an example to explain in detail. Figure 1 The left-right direction is the same as the second direction, and the front-back direction is the same as the first direction. The first conveyor 200 is a strong belt conveyor, and the second conveyor 300 is a chute belt conveyor. The overlapping transfer point pedestrian bridge system includes a first pedestrian bridge 1, an operating platform 2, a support ladder 3, a support plate 4 and a telescopic device 5.

[0046] The first pedestrian bridge 1 includes a first pedestrian bridge body, a first telescopic column 11 and an escalator 12. The first pedestrian bridge body is provided with guardrails 13 on both sides in the second direction, and warning signs are provided on the guardrails 13. The guardrails 13 are provided to form a protective effect to ensure the safety of people passing through. The first telescopic column 11 is provided below the first pedestrian bridge body. The number of the first telescopic columns 11 is six. Figure 1 As shown, six first telescopic columns 11 form support for the first pedestrian bridge 1. The first pedestrian bridge body is provided with escalators 12 on both sides thereof in the first direction, and the escalators 12 are provided to facilitate people to go up and down the bridge.

[0047] The operating platform 2 includes a table panel 21 and a second telescopic column 23. The table panel 21 is located at the bottom of the operating platform 2, and the table panel 21 forms the bottom surface of the operating space. A slide groove is provided on the table panel 21, and the slide groove extends in the second direction. Both ends of the slide groove in the second direction are open, and the slide groove cooperates with the support plate 4. The slide groove can not only guide and limit the sliding of the support plate 4, but the table panel 21 where the slide groove is located also supports the support plate 4, and when the support plate 4 is in the connection position with the support ladder 3, the table panel 21 and the support ladder 3 respectively form support for both sides of the support plate 4 in the second direction, so that the sliding of the support plate 4 and the support of pedestrians as the second pedestrian bridge are safer and more stable.

[0048] The second telescopic columns 23 are located below the table panel 21. There are two second telescopic columns 23. The operating platform 2 is arranged on the right side of the first pedestrian bridge 1, and the two second telescopic columns 23 and the first pedestrian bridge form a support for the operating platform 2.

[0049] Specifically, each of the first telescopic column 11 and the second telescopic column 23 includes a lower steel pipe 6 and an upper steel pipe 7, the upper steel pipe 7 can be nested in the lower steel pipe 6, the upper steel pipe 7 is provided with a plurality of radial first mounting holes 71, the lower steel pipe 6 is provided with a radial second mounting hole, and the bolts pass through the second mounting holes and the first mounting holes to fix the upper steel pipe 7 and the lower steel pipe 6. When installing the pedestrian bridge system, the height of the first telescopic column 11 and the second telescopic column 23 is adjusted according to the height of the first conveyor 200 and the second conveyor 300. After the height of the upper steel pipe 7 and the lower steel pipe 6 is adjusted, the first pedestrian bridge body and the table panel 21 are installed on the eight upper steel pipes 7. When using the bridge system of the embodiment of the present invention, there is no need to adjust the height.

[0050] The operating platform 2 is provided with a folding seat for use when personnel are working. The box door 24 is an inner opening door.

[0051] The support ladder 3 is fixedly arranged on the frame of the second conveyor 300. The upper end surface of the support ladder 3 is at the same height as the lower end surface of the support plate 4, so that the support ladder 3 supports the support plate 4.

The fixed end of the telescopic device 5 is arranged on one of the first pedestrian crossing bridge 1 and the operating platform 2, and the telescopic end of the telescopic device 5 is connected to the support plate 4. The arrangement of the telescopic device 5 provides power for the support plate 4 to slide along the slide groove of the platform panel 21, thereby improving the degree of automation of the pedestrian crossing system of the embodiment of the present invention. When it is necessary to cross the second conveyor 300, the telescopic device 5 drives the support plate 4 to move to the connection position connected with the support ladder 3. When the second conveyor 300 is in operation, the telescopic device 5 can drive the support plate 4 to disengage from the support ladder 3 to prevent the coal flow on the second conveyor 300 from causing impact damage to the support plate 4.

[0053] Specifically, the telescopic device 5 adopts a pneumatic telescopic cylinder, and the fixed end of the telescopic device 5 is fixedly arranged on the first pedestrian crossing bridge 1. The pneumatic telescopic cylinder is equipped with two switch buttons, which are respectively arranged on both sides of the second conveyor 300 in the second direction. When a person needs to pass through the second conveyor 300, the adjacent switch button can be pressed to start the pneumatic telescopic cylinder, and the pneumatic telescopic cylinder pushes the support plate 4 to slide out of the chute to reach the connection position with the support ladder 3, so that the person can pass through the support plate 4. After the person reaches the opposite side of the second conveyor 300, the adjacent switch button can be pressed to start the pneumatic telescopic cylinder, and the pneumatic telescopic cylinder drives the support plate 4 to retract so that the support plate 4 is retracted into the chute to avoid the coal flow on the second conveyor 300.

[0054] In some embodiments, the operating table 2 further includes a sealing plate 22, which is disposed on the table panel 21 and corresponds to the slide groove. The sealing plate 22 is located on the side of the slide groove away from the support ladder 3 in the second direction. A through hole is provided on the sealing plate 22, and the through hole matches the telescopic end of the telescopic device 5. The setting of the sealing plate 22 forms a protection for one side of the slide groove to prevent the dust in the environment from affecting the sliding of the slide groove and the support plate 4. At the same time, the telescopic end of the telescopic device 5 passes through the through hole to connect the support plate 4. When the telescopic device 5 drives the support plate 4 to slide, the through hole can also form a guide and limit for the telescopic end of the telescopic device 5 to prevent the telescopic device 5 from being deflected during the telescopic process, and further ensure the stability and safety of the sliding of the support plate 4.

[0055] In some embodiments, both sides of the support plate 4 in the first direction are provided with a placement groove 41, the placement groove 41 extends along the second direction, the cross-sectional outer contour of the placement groove 41 is "convex" and includes a vertical section and a transverse section, the upper end of the vertical section is open, the lower end of the vertical section is connected to the transverse section, and the transverse section extends along the first direction. The pedestrian crossing bridge system also includes a handrail 42, the handrail 42 is "n" shaped and includes a long column 421 and two short columns 422, the lower ends of the two short columns 422 are provided with a sliding shaft 423, the sliding shaft 423 is cylindrical, the sliding shaft 423 cooperates with the transverse section, the upper ends of the two short columns 422 are spaced apart and hinged to the long column 421, and the long column 421 cooperates with the vertical section.

[0056] The short column 422 can slide in the receiving groove 41 through the sliding shaft 423, the lower end of the short column 422 can rotate relative to the receiving groove 41 through the sliding shaft 423, and the upper end of the short column 422 can rotate relative to the long column 421, so that the handrail 42 can be retracted into the receiving groove 41. When the handrail 42 is in a retracted state, the two sliding shafts 423 are located in the middle of the receiving groove 41 in the second direction and are opposite to each other, the upper ends of the two short columns 422 are located on both sides of the receiving groove 41 in the second direction, and the long column 421 is located in the receiving groove 41. When the support plate 4 is in the connection position with the support ladder 3, the long column 421 can be pulled upward to make the two sliding shafts 423 slide to both sides of the receiving groove 41 and the two short columns 422 stand up, so that the handrail 42 is in an expanded state, such as Figure 4 As shown, the personnel on the support plate 4 are protected to ensure the safety of pedestrians crossing the bridge. After passing through the support plate 4, the personnel press down the long column 421 to retract the handrail 42 into the support plate 4, and then the telescopic device 5 can drive the support plate 4 to slide to the left side of the slide groove of the table panel 21, so as to realize the retraction of the support plate 4 to the table panel 21.
