Description

Technical Field

[0001] The invention relates to the technical field of airport ground equipment, in particular to a sliding roof of a passenger elevator. Background Art

[0002] In order to ensure that passengers can meet the rain protection needs when going up and down the stairs, passenger boarding stairs are usually equipped with semi-enclosed awnings, and some are equipped with fully enclosed awnings to meet the lateral wind protection needs. Due to the docking with the aircraft cabin door, the cabin door needs to be opened, and the platform awning only partially extends forward and does not fully cover the cabin door. Therefore, a sliding awning that can cover the cabin door is needed, which can not only meet the needs of sheltering passengers from wind and rain, but also do not affect the normal opening and closing of the cabin door, and can ensure the normal driving of the vehicle.

[0003] At present, the main solution is to configure a fully enclosed folding awning (transplant the corridor bridge head to the passenger elevator platform). However, the folding awning needs to be configured with a wide platform to fully wrap the hatch door into the awning. The width and height of the entire vehicle are increased, and the mass of the head causes the center of gravity to move forward, increasing the difficulty of driving. At the same time, it is expensive. Therefore, it is necessary to design a sliding canopy solution to meet various needs while controlling costs. Summary of the invention

[0004] The purpose of the present invention is to provide a sliding canopy for a passenger elevator, which solves the technical problems that the fully enclosed corridor bridge head used in the existing passenger boarding stairs is difficult and expensive to use, while the semi-enclosed canopy cannot meet the full shielding requirements.

[0005] To achieve the above-mentioned objectives, the present invention provides a sliding canopy for a passenger elevator, comprising a telescopic canopy, a left bearing beam, a right bearing beam, a left handrail limit assembly, a right handrail limit assembly, a left canopy fixed guide rail frame, a right canopy fixed guide rail frame, an auxiliary support locking weldment and an electric control component, wherein the left bearing beam and the right bearing beam are fixed to the upper layer in the telescopic canopy, and the left handrail limit assembly and the right handrail limit assembly are fixed to the lower layer, the left canopy fixed guide rail frame and the right canopy fixed guide rail frame are respectively fixed to both sides of the telescopic canopy and remain parallel to the telescopic canopy, the auxiliary support locking weldment is respectively fixed to the outer sides of the left and right columns of the telescopic canopy, and the electric control component is used to control the automatic extension and retraction of the telescopic canopy.

[0006] The telescopic awning is processed into a door arc-shaped curved beam using awning aluminum profiles, and forms a door-type frame structure with the straight beam awning aluminum profiles.

[0007] Wherein, an anti-collision rubber strip is fixed on the front side of the door arc-shaped curved beam.

[0008] Wherein, the electric control component includes a machine-approaching induction switch and an in-position travel switch, the machine-approaching induction switch is fixed to the lower side of the anti-collision rubber strip in front of the telescopic awning, and the in-position travel switch is arranged outside the telescopic awning.

[0009] Among them, a low-voltage motor and a rotating sprocket are installed under the left canopy fixed guide rail frame. The low-voltage motor outputs to the driving sprocket through the bearing seat. A closed chain is formed between the driving sprocket and the rotating sprocket. The driving sprocket rotates with the low-voltage motor and drives the chain to rotate.

[0010] Among them, after the retractable canopy is installed, the side surfaces of the lower limit plates of the left handrail limit assembly and the right handrail limit assembly are designed with locking holes densely arranged in a straight line, and the auxiliary support locking weldments on both sides are designed with spring locks.

[0011] In order to ensure the gap between the auxiliary support locking weldment and the limiting plate, a nylon sleeve is installed on the inner side of the auxiliary support locking weldment to prevent the limiting plate from being worn.

[0012] A sliding canopy for a passenger ladder vehicle of the present invention is provided in front of a door platform of the passenger boarding ladder, thereby meeting the requirements for wind and rain protection above and on both sides of the passenger ladder platform at the entry and exit door position, and further meeting the use requirements of passengers in front of the door. At the same time, the width of the canopy does not exceed the width of the entire vehicle, the front and rear sliding stroke is large, the weight is light, there is no difficulty in use, and the cost is controllable. In addition, the shapes of the ladder body and the canopy match each other, and the overall appearance is coordinated. In addition, the sliding canopy can be operated in two modes: electric drive and manual drive, and it needs to be manually locked after driving the sliding canopy, thereby meeting the requirements of civil aviation equipment use standards, and solving the technical problems that the fully enclosed corridor bridge head used by the existing passenger boarding ladder is difficult and expensive to use, and the semi-enclosed canopy cannot meet the full shielding requirements.

DETAILED DESCRIPTION

[0018] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0019] First embodiment:

[0020] See also Figures 1 to 3 The present invention provides a sliding canopy for a passenger elevator, comprising a telescopic canopy 1, a left bearing crossbeam 2, a right bearing crossbeam 3, a left handrail limit assembly 4, a right handrail limit assembly 5, a left canopy fixed guide frame 6, a right canopy fixed guide frame 7, an auxiliary support locking weldment 8 and an electric control component, wherein the electric control component comprises a machine-supporting induction switch 22 and an in-position travel switch 23.

[0021] In the present embodiment, a sliding canopy is installed in front of the door platform of the passenger boarding ladder, so as to meet the needs of wind and rain protection above and on both sides of the passenger ladder platform at the entry and exit door position, and thus can meet the use needs of passengers in front of the door. At the same time, the width of the canopy does not exceed the width of the entire vehicle, the front and rear sliding stroke is large, the weight is light, there is no difficulty in use, and the cost is controllable. In addition, the shapes of the ladder body and the canopy match each other, and the overall appearance is coordinated. In addition, the sliding canopy can be operated in two modes: electric drive and manual drive, and it needs to be manually locked after driving the sliding canopy, so as to meet the requirements of civil aviation equipment use standards, and solve the technical problems that the fully enclosed corridor bridge head used by the existing passenger boarding ladder is difficult and expensive to use, and the semi-enclosed canopy cannot meet the full shielding requirements.

[0022] Among them, the left bearing beam 2 and the right bearing beam 3 are fixed to the upper layer in the telescopic awning 1, and the left handrail limit assembly 4 and the right handrail limit assembly 5 are fixed to the lower layer. The left awning fixed guide rail frame 6 and the right awning fixed guide rail frame 7 are respectively fixed on both sides of the telescopic awning 1 and remain parallel to the telescopic awning 1. The auxiliary support locking weldment 8 is respectively fixed to the outer sides of the left and right columns of the telescopic awning 1. The electric control component is used to control the automatic extension and retraction of the telescopic awning 1. The left awning fixed guide rail frame 6 and the right awning fixed guide rail frame 7 are ensured to be parallel to the telescopic awning 1 through installation fine-tuning.

[0023] Secondly, the left bearing crossbeam 2 and the right bearing crossbeam 3 are each installed with 4 sets of rolling bearings to ensure that the entire telescopic awning 1 can move linearly forward and backward in the left awning fixed guide frame 6 and the right awning fixed guide frame 7. At the same time, the left awning fixed guide frame 6 and the right awning fixed guide frame 7 also play a major supporting role for the telescopic awning 1.

[0024] Again, the retractable awning 1 is made of awning aluminum profiles to form a door arc-shaped curved beam 9, and forms a door-type frame structure with the straight beam awning 10 aluminum profile. The door arc-shaped curved beam 9 and the straight beam are connected and fixed at the joint with a pressure plate 11, and the frame is embedded with an awning endurance plate 12. The roof of the awning endurance plate is dark in color, and transparent plates 13 are embedded on both sides. An anti-collision rubber strip 21 is fixed to the front side of the door arc-shaped curved beam 9.

[0025] At the same time, the machine-supporting sensing switch 22 is fixed to the lower side of the anti-collision rubber strip in front of the telescopic awning 1, and the in-place travel switch 23 is arranged outside the telescopic awning 1. The machine-supporting sensing switch 22 senses the aircraft deck and cabin door that may be in contact with it, and controls the telescopic awning 1 to stop automatically extending. When the telescopic awning 1 returns to its position, the in-place travel switch 23 is sensed and sends an electrical signal to move the vehicle.

[0026] In addition, a low-voltage motor 14 and a rotating sprocket 16 are installed under the left awning fixed guide rail frame 6. The low-voltage motor 14 outputs to the driving sprocket 15 through the bearing seat. A closed chain 17 is formed between the driving sprocket 15 and the rotating sprocket 16. The driving sprocket 15 rotates with the low-voltage motor 14 to drive the chain 17 to rotate. The inner extension support plates of the left bearing beam 2 and the right bearing beam 3 are fixed to the chain 17. The left bearing beam 2 and the right bearing beam 3 are driven to move forward and backward by the chain 17. The left bearing beam 2 and the right bearing beam 3 are fixed in the telescopic awning 1. The chains 17 on the left and right sides drive the telescopic awning 1 to move forward and backward through the rotation of the low-voltage motor 14.

[0027] Finally, after installing the retractable awning 1, the side surfaces of the lower limit plates of the left handrail limit assembly 4 and the right handrail limit assembly 5 are designed with locking holes 18 densely arranged in a straight line, and the auxiliary support locking weldments 8 on both sides are designed with spring locks 19. When working, the locking tongue is extended and inserted into the locking hole 18 of the limit plate to lock and fix it. When the vehicle is driving and the machine operation is completed, the spring lock 19 is used to ensure mechanical locking. In order to ensure the gap between the auxiliary support locking weldment 8 and the limit plate, a nylon sleeve 20 is installed on the inner side of the auxiliary support locking weldment 8 to prevent the limit plate from being worn. The upper layer of the auxiliary support locking weldment 8 is welded with a handrail tube to facilitate the operator to manually move the retractable awning 1.

[0028] When a sliding canopy for a passenger elevator vehicle of the present embodiment is used, the retractable canopy 1 can be driven to move by electric drive and manual drive. When driven by electric drive, first, the low-voltage motor 14 is started, so that the power output by the output end of the low-voltage motor 14 drives the driving sprocket 15 to rotate following the low-voltage motor 14, thereby driving the chain 17 to rotate, and then driving the left bearing beam 2 and the right bearing beam 3 to move forward and backward. The retractable canopy 1 can be driven to move forward and backward through the forward and backward movement of the left bearing beam 2 and the right bearing beam 3. When driven manually, the operator manually moves the retractable canopy 1 through the handrail tube. The retractable awning 1 is moved to realize the forward and backward movement of the retractable awning 1. During the forward and backward movement of the retractable awning 1, the aircraft deck and cabin door that may be touched are sensed by the machine-supporting sensing switch 22, and the automatic extension of the retractable awning 1 is controlled to be stopped. When the retractable awning 1 moves to a suitable position, the locking tongue is extended again, and the locking tongue is stuck into the locking hole 18 of the limit plate, so that it can be locked and fixed. When the vehicle is driving and the aircraft operation is completed, the spring lock 19 is used to ensure mechanical locking. When the retractable awning 1 is returned to its position, the in-position travel switch 23 is sensed, and an electrical signal is sent to move the vehicle.

[0029] In summary, by installing a sliding canopy in front of the door platform of the passenger boarding ladder, the wind and rain protection needs of the passenger ladder platform at the entrance and exit door position can be met, and then the use needs of passengers in front of the door can be met. At the same time, the width of the canopy does not exceed the width of the entire vehicle, the front and rear sliding stroke is large, the weight is light, there is no difficulty in use, and the cost is controllable. In addition, the shape of the ladder body and the canopy match each other, and the overall appearance is coordinated. In addition, the sliding canopy can be operated in two modes: electric drive and manual drive, and it needs to be manually locked after driving the sliding canopy, so that it can meet the requirements of civil aviation equipment use standards, and solves the technical problems that the fully enclosed corridor bridge head used by the existing passenger boarding ladder is difficult and expensive to use, and the semi-enclosed canopy cannot meet the full shielding requirements.
