The invention provides a telescopic boarding bridge, which aims at the improvement of the original telescopic boarding bridge, and as shown in figure 1, the main structure of the telescopic boarding bridge comprises a telescopic passage device which consists of at least two inner passages 11 and outer passages 12 which are sleeved with each other, wherein the inner passages 11 and the outer passages 12 move mutually along the longitudinal direction, so that the length of the telescopic passage device can be changed to realize the telescopic effect, and the common matching structure can refer to figures 2 to 8, and the two sides of the lower parts of the inner passages 11 and the outer passages 12 are provided with passage telescopic roller devices 14; for solving the problem, the invention adopts the scheme that a walkway device 2 is added to lift the walkway ground of the outer passage 12, so that the walkway ground is exactly level with the walkway ground of the inner passage 11, and the purposes of safe and stable walking are achieved. In particular, with reference to fig. 1, the present invention leaves a bottom space 15 between the inner channel 11 and the outer channel 12; and the walkway installation 2 includes several floors 21 connected together, the first end of the walkway installation 2 is located in the bottom space 15, usually fixed at the bottom of the outer channel 12, the second end of the walkway installation 2 is fixed at or near the front end of the outer channel 12, wherein the installation position of the second end of the walkway installation 2 is higher than the installation position of the first end and is approximately level with the bottom aisle of the inner channel 11; under the structure, when the telescopic passage device is unfolded, namely the inner passage 11 and the outer passage 12 are relatively moved and unfolded, as shown in fig. 5, the floor 21 originally positioned in the bottom space 15 of the walkway device 2 is pulled out and exposed to the outer passage 12 due to the relative movement of the inner passage 11, and on the basis of the structure action, a supporting device 3 is added to support the floor 21 pulled out to the outer passage 12, so that the floor 21 is level with the second end of the walkway device 2, and the pulled-out and supported floor 21 is basically level with the walkway floor of the inner passage 11, and forms a flat walkway for passengers to walk together with the walkway floor of the inner passage 11; when the telescopic channel device is contracted, namely the inner channel 11 and the outer channel 12 move relatively and contract, the floor 21 positioned on the outer channel 12 is retracted into the bottom space 15 because of the relative movement of the inner channel 11, so that the contraction action of the telescopic channel device is not interfered. Since the walkway installation 2 has a high lifting movement when moving out of and into the bottom space 15, the invention can be provided with a guide 4 at the end near the inner channel 12 for lifting or lowering the passing floor 21. As shown in fig. 5 and 6, a shielding device 32 can be separately added above the supporting device 3 to shield the supporting device 3 and the corresponding supporting structure, so as to protect the mechanical structure and passengers, and make the aisle simple and beautiful.
The purpose of the supporting device is to support the floor, which can be fixed in the outer channel or under the floor according to the choice of design scheme, while the choice of scheme of the guiding device is usually adjusted according to the specific structure of the supporting device. Fig. 2 to 12 show a first preferred embodiment of the supporting means and the guiding means of the present invention, wherein the supporting means 3 is a supporting table disposed at one side or both sides of the outer channel 12, which can be generally implemented by an angle beam, as long as it has a protruding step to implement the supporting function.
Correspondingly, the guiding device 4 is a guiding plate, which is arranged near the supporting device 3 in a matching way, an oblique transition rail 41 matched with the end part of the floor 21 is arranged on the guiding plate, the upper end of the oblique transition rail 41 is connected with the supporting device 3, the lower end is matched near the entrance of the bottom space 15, when the floor 21 extends out of the bottom space 15, the floor firstly slides onto the transition rail 41, and gradually rises to the supporting device 3 through the transition rail 41 in the following movement, and then moves to the supporting device 3 to be supported.
In the concrete structure, since the supporting device 3 will obstruct the floor 21 in the ascending or descending state, a structure is necessary to solve the problem, in the embodiment, the two ends of the floor 21 are provided with the telescopic force-bearing parts 22 matched with the supporting device 3, and when the floor 21 is retracted into the bottom space 15, the telescopic force-bearing parts 22 are contracted to lose the matching relation with the supporting device 3, so that the floor can be successfully retracted. As shown in fig. 4, 5, 6, 11, and 12, in a preferred structure, the elastic force-bearing part 22 is an elastic expansion shaft disposed at the end of the floor 21, the inclined transition rail 41 is disposed at a position where the elastic expansion shaft can be pressed, so that the elastic expansion shaft is compressed and contracted when the floor 21 is engaged with the inclined transition rail 41, and extends out after the floor 21 completely extends out of the bottom space 15, and is engaged with the supporting device 3 to support the floor 21, and in order to be able to press and contract the elastic expansion shaft when the floor 21 is contracted back into the bottom space 15, an inclined surface 42 may be disposed at the engagement part of the inclined transition rail 41 and the supporting device 3 to guide the elastic expansion shaft.
Another exemplary embodiment of the supporting means and guiding means is shown in fig. 13 to 16, in which the supporting means 3 is a plurality of telescopic supporting shafts arranged longitudinally inside the outer tunnel 12, which support the end of the floor 21, thereby making the floor 21 level with the bottom aisle of the inner tunnel 11 and capable of carrying pedestrians; in order to not hinder the floor 21 from contracting into the bottom space 15, a pressing part 111 for pressing the telescopic support shaft is arranged outside the inner channel 11, so that when the telescopic channel device contracts, the pressing part 111 sequentially presses and contracts the contacted telescopic support shaft along with the movement of the inner channel 11 relative to the outer channel 12, and the telescopic support shaft is separated from the end part of the floor 21 after being pressed and contracted, so that the floor 21 loses support, descends along with the guiding of the guiding device 4 and contracts back into the bottom space 15; when the telescopic channel device is unfolded, the floor 21 is pulled to extend out of the bottom space 15 and gradually rises along with the guidance of the guiding device 4, and simultaneously, due to the movement of the inner channel 11 relative to the outer channel 12, the telescopic support shaft which is originally positioned between the inner channel 11 and the outer channel 12 and is extruded by the jacking part 111 is gradually separated from the inner channel 11 and the jacking part 111 thereof, and is further extended, so that the floor 21 at the corresponding position can be supported.
In this embodiment, the retractable support shaft can be implemented in many ways, for example, a retractable structure that can be retracted and extended can be adopted, but in the illustrated embodiment of the present invention, the structure is a pivoting structure, in which the retractable support shaft is pivoted with the inner side of the outer channel 12, and the pivoting shaft is perpendicular to the longitudinal direction of the outer channel, and the retracted state is the pressing of the pressing portion 111 to turn to the outer channel 12, and the extended state is the rotation away from the outer channel 12. In addition, because the end part of the telescopic supporting shaft and the jacking part 111 are frequently extruded and slide, the end part of the telescopic supporting shaft can be provided with the pulley 31 matched with the jacking part 111 and is contacted with and slides on the jacking part 111, and the mechanical abrasion is reduced.
In this embodiment, the guiding means 4 is composed of a plurality of guiding rollers 43 sequentially distributed from the bottom space 15 to the outer channel 12, and the guiding rollers 43 receive the floor 21 and have guiding and bearing sliding effects when the floor 21 is extended or retracted into the bottom space 15.
Of course, the above description only describes two exemplary embodiments, and the present invention may have more embodiment structures according to the technical solutions of the claims of the present invention, and details are not described herein again.
As mentioned above, the invention uses the walkway device 2 to realize the complete leveling of the ground of the passageway in the retractable walkway device, the floor 21 of the walkway device 2 can adopt a structure which is hinged in sequence or a structure which is connected in sequence by chains, or other connection modes; in order to solve the problem that the length of the walkway installation 2 is not changed greatly when the walkway installation is located in the bottom space 15 and the outer channel 12, but a certain amount of extrusion is caused as a whole due to the height difference, the invention fixes the walkway installation 2 at the bottom of the outer channel 12 through a walkway tensioning device 5 with elasticity, specifically, the walkway tensioning device 5 comprises a fixing part 51 fixedly arranged on the outer channel 12 and a connecting part 52 connected with the walkway installation, the connecting part 52 is connected with the fixing part 51, and an elastic part 53 is pressed between the connecting part 52 and the fixing part 51. In this way, when the walkway installation is redundantly compressed due to a change in position, the walkway tensioning device 5 will tension the walkway installation, and when the walkway installation is not long enough, the walkway tensioning device 5 is pulled to compensate for the lack of length.
In the part of the walkway installation just extending out of the bottom space 15, due to the structure relationship or the relationship of the guiding device 4, the walkway installation can not be immediately leveled with the walkway ground of the inner passage 11, thus the trouble is caused when the passenger passes through the walkway installation, in order to solve the problem, a transition pedal 6 can be pivoted at the end of the walkway of the inner passage 11, and the transition pedal 6 is just connected with the floor 21 on the outer passage 12, thus the concave position can be filled, and the leveling of the whole walkway ground can be achieved. In addition, the pivot structure of the transition pedal 6 needs to be supported, and cannot hinder the extending, retracting and lifting actions of the floor 21, so that a cam motor 61 capable of jacking the transition pedal 6 can be arranged at the bottom of the transition pedal 6, when the floor 21 acts, the cam motor 61 jacks up the transition pedal 6 to leave enough movement space for the floor 21, and after the floor 21 is completely unfolded, the cam motor 61 descends, and the transition pedal 6 is suspended with the floor 21.
The boarding bridge has various using environments, and needs a corresponding drainage structure for coping with rainy weather, wherein rainwater usually flows down along the outer wall of the outer channel 12, and part of rainwater possibly enters between the outer channel 12 and the inner channel 11 and flows down along the wall surface of the channel, in the invention, a drainage baffle 16 can be arranged above the channel telescopic roller device 14, the drainage baffle 16 is provided with an inclined surface inclined towards the outer side, the lower end side of the outer channel 12 is provided with a drainage hole 17 corresponding to the inclined surface of the drainage baffle 16, the water flowing down along the wall surface of the channel flows to the drainage hole 17 through the inclination of the drainage baffle 16 and flows out from the drainage hole 17, and for better drainage effect, a drainage pipeline 18 can be arranged on the side wall of the front end of the inner channel 11, the upper end of the drainage pipeline 18 is positioned at the upper part of the inner channel 11, and the lower end of the drainage pipeline is positioned above the, so that the water flowing down from the drain pipe 18 can be discharged along with the structure of the drain trap 16. Furthermore, the shielding device 32 can be spaced from the side wall of the inner passage 11 to prevent water on the side wall of the inner passage 11 from flowing to the shielding device 32.
The above embodiments are described by using the most basic combination of two channels, i.e. the inner channel 11 and the outer channel 12, while in the actual boarding bridge structure, the retractable channel device will use more than two channel combination schemes, such as the three-channel structure shown in fig. 9 to 12, and of course, the structure principle is the same as that of the two-channel scheme, i.e. the first channel 101 is equivalent to the inner channel of the second channel 102, and the second channel 102 is equivalent to the inner channel of the third channel 103, so that two sets of walkway devices 2 and corresponding matching structures are correspondingly required to achieve complete leveling of the walkway floor of the entire retractable channel device.
Compared with the existing boarding bridge, the invention not only ensures that the height of the passageway ground of the passageway device is consistent, improves the safety performance of the product, and ensures that passengers walk more safely and conveniently; moreover, because the structure is simple, the additional parts are fewer, the occupied space is smaller, and the weight of the boarding bridge can be effectively controlled, the additional spaces can be used for installing auxiliary equipment of the boarding bridge as shown in fig. 17, and the reasonability of the structure is ensured.
