Description

Technical Field

[0001] The utility model relates to the field of shielding doors, and more specifically to a full-height shielding door based on a direct-drive servo system. Background Art

[0002] With the continuous advancement of urban modernization, rail transit has developed rapidly, and rail transit full-height shielding doors have been increasingly widely used due to their safety, energy saving, and environmental protection. Therefore, full-height shielding doors have gradually become an indispensable and important equipment in modern subways.

[0003] At present, most shielding door drive systems on the market use traditional DC brushless motors. For example, Ningbo Line 1 uses DC brushless motors. DC brushless motors usually have slight vibrations when starting at low speed. If the speed increases and the commutation frequency increases, the vibration phenomenon will not be felt, and resonance is easy to form. Because everything has an inherent vibration frequency, if the vibration frequency of the brushless motor is the same as or close to the vibration frequency of the door frame or support frame of the shielding door, resonance is easy to form. Therefore, shielding doors driven by brushless motors sometimes make a buzzing sound.

[0004] Due to the relatively low accuracy and control performance of brushless DC motors, they are gradually unable to meet the requirements of shielding door scenarios with high position and speed accuracy. In addition, the current full-height shielding door has a relatively complex structure for driving the sliding door body to slide, and occupies more space. Therefore, it is necessary to propose a full-height shielding door based on a direct-drive servo system to solve the above problems. Utility Model Content

[0005] The utility model provides a full-height shielding door based on a direct-drive servo system in order to overcome at least one defect (deficiency) of the prior art.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows: a full-height shielding door based on a direct-drive servo system, comprising a column, an aluminum alloy beam, a servo motor, a fixed door body, a sliding door body and an emergency door body;

[0007] The aluminum alloy crossbeam is arranged on the column, and a driving belt connected to the servo motor is arranged on the aluminum alloy crossbeam;

[0008] The fixed door body and the emergency door body are respectively arranged on the left and right sides of the sliding door body. The top of the sliding door body is slidably set on the aluminum alloy beam through a hanger. The hanger is provided with a driving belt clamping device connected to the driving belt, so that the sliding door body can reciprocate under the drive of the servo motor. Through the setting of the hanger, the top of the sliding door body can be slidably set on the aluminum alloy beam. Since a driving belt clamping device connected to the driving belt is also provided on the hanger, the driving belt can drive the sliding door body to reciprocate synchronously under the drive of the servo motor. In addition, the design of the servo motor can accurately control the position, speed and torque under large loads and high speeds. It has the characteristics of high precision, fast control response and strong reliability, and is suitable for shielding door scenes with high requirements for position and speed.

[0009] Further, the pendant includes a pendant mounting seat, a roller, a roller bearing and a locking base;

[0010] The pendant mounting seat is divided into a first cavity and a second cavity which are independent of each other by a partition plate;

[0011] The rollers are respectively arranged in the first cavity and the second cavity through roller bearings;

[0012] One end of the locking base is arranged at the bottom of the hanger mounting seat, and the other end is connected to the sliding door body. The hanger mounting seat is divided into a first cavity and a second cavity that are independent of each other, and rollers are respectively arranged on the first cavity and the second cavity, so that the sliding door body can be moved conveniently, and the locking base can lock the sliding door body. Therefore, after the hanging device is set, the sliding door body can reciprocate on the aluminum alloy beam.

[0013] Furthermore, lateral sealing baffles are provided on the outer sides of the first cavity and the second cavity. The lateral sealing baffles can provide enhanced support for the roller bearing and protect the roller from the outer side.

[0014] Further, the driving belt clamping device comprises a belt clamp, a connecting pressure block and an upper sealing baffle;

[0015] The belt clip is mounted on the pendant mounting seat, one end of the connecting pressing block is connected to the belt clip, and the other end is fixed to the driving belt;

[0016] One end of the upper sealing baffle is arranged on the belt clamp, and the other end is blocked above the roller. Because one end of the connecting pressure block is connected to the belt clamp, and the other end is fixed on the driving belt, when the driving belt moves under the drive of the servo motor, it will drive the belt clamp to move at the same time, and the belt clamp is installed on the pendant mounting seat. Therefore, under the drive of the belt clamp, the sliding door body can be opened and closed. In addition, the upper sealing baffle can be blocked above the roller, and the roller can be protected from above the roller.

[0017] Furthermore, the belt clamp, the connecting pressure block and the upper sealing baffle are an integrated structure, and the integrated belt clamp, the connecting pressure block and the upper sealing baffle can effectively simplify the overall structure of the driving belt clamping device.

[0018] Further, the aluminum alloy crossbeam includes a crossbeam body, a first horizontal support block and a second horizontal support block;

[0019] The first horizontal support block and the second horizontal support block are sequentially arranged on the crossbeam body from top to bottom;

[0020] The driving belt is arranged on the first horizontal support block, and the second horizontal support block is provided with a limiting protrusion for limiting the roller;

[0021] The beam body, the first horizontal support block, the second horizontal support block and the limiting protrusion are an integrated structure. The first horizontal support block can be used to accommodate the drive belt, and the second horizontal support block can be used for the sliding of the roller. Therefore, by sequentially arranging the first horizontal support block and the second horizontal support block on the beam body, the drive belt and the roller can be arranged in layers on the beam body, which makes the structure more concise and convenient for installation and maintenance.

[0022] Furthermore, it also includes a driven wheel, and the driven wheel and the servo motor are respectively arranged on both sides of the aluminum alloy beam, one end of the driving belt is sleeved on the outside of the driven wheel, and the other end is sleeved on the outside of the servo motor. Since the two ends of the driving belt are respectively sleeved on the servo motor and the driven wheel, when the servo motor rotates, the driving belt drives the driven wheel to rotate synchronously. Since the top of the sliding door body is connected to the driving belt through the hanger and the driving belt clamping device, the movement of the driving belt can control the sliding opening and closing of the sliding door body.

[0023] Furthermore, it also includes a gate-controlled drive control box, which is connected to the servo motor. Through the setting of the gate-controlled drive control box, the servo motor can be easily controlled and powered.

[0024] Furthermore, one side of the emergency door body is rotatably arranged on a column through a rotating shaft, and an emergency door switch sensor is provided on the other side of the emergency door body. The emergency door switch sensor is connected to the door control drive control box. By controlling the emergency door switch sensor, it is convenient to remotely control the opening and closing of the emergency door body. When the emergency door switch sensor is in the open state, personnel can push open the corresponding emergency door body through the rotating shaft to perform emergency rescue or maintenance work.

[0025] Furthermore, the column is provided with an embedded part with adjustable height. Through the provision of the embedded part with adjustable height, when the column is installed, the installation height of the column can be adjusted as needed, which is simple and convenient.

In addition, the design of the servo motor can accurately control the position, speed and torque under a large load and high speed. It has the characteristics of high precision, fast control response and strong reliability, and is suitable for shielding door scenes with high requirements for position and speed.
