Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a lifting type railway platform safety guardrail. Background Art

[0002] At present, the platforms of various railway bureaus are all open-style with no protective measures. When passengers are waiting for the train, there are only passenger attendants patrolling and supervising on the platform. According to the "Railway Passenger Transport Management Rules", there are an average of 1.5 passenger attendants on each platform, and the train has at least 8 carriages and at most 16 carriages. If there is a train coming from only one side, 3 people can supervise a train at the same time; if there are trains coming from both sides at the same time, there are 1.5 people on one side, 8 or 16 carriages, and hundreds or thousands of people waiting for the train are distributed in each carriage. It is impossible for three people to supervise them all. Every year, many passengers fall off the platform for different reasons and get into accidents, which not only brings inconvenience to other passengers, but also has a great impact on the station.

[0003] Based on the above problems, a fence is needed to provide certain protection for passengers when they are waiting for the vehicle, to prevent people, luggage, and large items from accidentally falling onto the platform, causing personal and property losses. Utility Model Content

[0004] In view of the problems and shortcomings in the prior art, the utility model provides a lifting type railway platform safety guardrail.

[0005] The technical solution of this utility model is as follows:

[0006] A lifting type railway platform safety guardrail comprises two brackets arranged vertically at intervals, a guardrail arranged horizontally between the two brackets, and a lifting mechanism between the guardrail and the brackets for driving the guardrail to move up and down;

[0007] The lifting mechanism includes:

[0008] A linear moving module comprises a guide rail and a slide block which are slidably matched, wherein the guide rail is vertically fixed on the bracket;

[0009] A driving assembly, including a motor and a gear, is connected to the slider through a motor support plate and moves up and down with the slider, wherein the output shaft of the motor is perpendicular to the bracket and located between the bracket and the guardrail, and is connected to the gear;

[0010] A first rack is vertically fixed on the side of the bracket close to the guardrail and meshes with the gear;

[0011] The second rack is vertically fixed on the side surface of the guardrail close to the bracket and meshes with the gear.

[0012] The working principle of the lifting mechanism is:

[0013] When the guardrail rises, the motor rotates, driving the gear to rotate. The gear meshes with the first rack fixed on the bracket rail, and the gear drives the motor to rise along the bracket rail. At the same time, the second rack also meshes with the gear. Since the first rack is fixed, the second rack will generate an upward force. The second rack is connected to the guardrail. Under the action of the aforementioned upward driving force, the second rack drives the guardrail to rise vertically, triggering the limit switch set on it, the motor stops rotating, and the guardrail stops rising. When the guardrail descends, the motor reverses. The principle is the same as above and will not be repeated.

[0014] In a specific embodiment, the height of the bracket, the first rack and the second rack is not less than 2m, so that the height of the guardrail after raising is not less than 2m, which is convenient for passengers to get on and off the vehicle.

[0015] The guardrail includes multiple groups of rope units arranged vertically in parallel. The rope unit includes two fixed blocks and a safety rope connecting the two fixed blocks. A plurality of safety ropes are arranged at intervals along the height direction of the fixed blocks, and the fixed blocks are connected to the second rack. The spacing of the safety ropes is 100-130mm. Preferably, three groups of rope units are arranged side by side in the vertical direction, and the number of safety ropes in each group of rope units is four, and they are arranged at intervals up and down, and the spacing is preferably 120mm. It can not only prevent people from falling off the platform, but also prevent luggage and large personal items from accidentally falling, thereby reducing personal injury and property loss.

[0016] An infrared detection sensor is installed on the side of the bracket close to the train, which is connected to the motor through the control unit to detect the arrival of the train. When the train arrives and stops, the control unit controls the motor to start, drives the gear to rotate, and drives the guardrail to rise through the transmission of the first rack and the second rack. After it rises to the limit position of not less than 2m, the limit switch is triggered, the motor is powered off, and the guardrail stops rising. After the train starts and leaves, the motor reverses, the guardrail falls and returns to the protective state to prevent passengers, luggage and items from falling onto the platform.

[0017] The side of the bracket close to the platform is equipped with a human body induction sensor and a voice warning module, which is used to play a voice prompt when a human body is detected approaching. The function of the pneumatic warning to passengers is to prevent passengers from getting too close to the edge of the platform and causing accidents.

[0018] The bracket is also provided with a manual lifting button, which is electrically connected to the motor, and is used to manually control the lifting and lowering movement of the guardrail, playing the role of manual and automatic dual control to prevent automatic control failure.

[0019] The manual lift button is equipped with a fingerprint recognition device to prevent passengers or other non-staff from making mistakes.

[0020] In a specific embodiment, the linear motion module includes two vertically spaced guide rails and two sliders respectively slidably matched with the two guide rails. The guide rails and sliders arranged in parallel and spaced relation can improve the rigidity and straightness of the linear motion module, provide a stable support force for the guardrail, and ensure the straightness of the guardrail when it moves up and down.

[0021] The beneficial effects of the utility model are:

[0022] A lifting mechanism is provided between the guardrail and the bracket to drive the guardrail to move up and down, and after the infrared detection sensor detects that the train has arrived at the station and stopped, the motor is driven to rotate, so that the guardrail rises from a protective state to an open state to facilitate passengers to get on and off the train; the lifting mechanism includes a linear motion module, a motor, a gear, a first rack and a second rack, the linear motion module includes a sliding guide rail and a slider, the guide rail is vertically fixed on the bracket, the slider is connected to the motor through a motor support plate, the motor output shaft is perpendicular to the bracket and is located between the bracket and the guardrail, and a gear is connected to it; the first rack is vertically fixed on the side of the bracket close to the guardrail and meshes with the gear; the second rack is vertically fixed on the side of the guardrail close to the bracket and meshes with the gear.
