Description

Technical Field

[0001] The present application relates to the field of gates, and in particular to a subway entry and exit gate with a protective structure. Background Art

[0002] Subway entrance and exit gates are important automated equipment used to control the entry and exit of passengers in subway stations. They play a key role in ensuring the orderliness, safety and efficiency of passenger flow. There are many types of gates at different stations according to their specific needs, including but not limited to fan gates, swing gates, three-roller gates, etc. Each type has its own applicable scenarios and advantages;

[0003] The fan blade design of the fan gate supports fast opening and closing, and can complete the passage verification of a single passenger in a short time, which is particularly suitable for subway stations with high passenger flow. The fan blades of existing fan gates are often rotated on a swinging protection plate, and the opening and closing of the fan blades are driven by a driving mechanism. However, when the fan blades of a swinging protection plate are frequently opened and closed at high speed, it is easy for the fan blades to swing abnormally or deviate, and it is easy for the passing passengers to be clamped due to the abnormal opening and closing of the fan blades. At the same time, a single swinging protection plate bears all the guiding pressure when the fan blades rotate, which will accelerate the wear of the connection between the swinging protection plate and the fan blades, thereby affecting the service life of the fan blades. In order to solve the above problems, a subway entry and exit gate with a protective structure is proposed.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0024] The following is combined with Figure 1-7 This application is described in further detail.

[0025] The present application embodiment discloses a subway entry and exit gate with a protective structure. Figure 1-7 A subway entrance and exit gate with a protective structure comprises a gate body 1, a rotating shaft 5 is rotatably provided on the gate body 1, an active fan blade 3 and a driving assembly for driving the active fan blade 3 to rotate are provided on the gate body 1, the active fan blade 3 is fixed to the rotating shaft 5, a driven fan blade 4 is slidably provided in the active fan blade 3, and two swing protection plates 6 for protecting the active fan blade 3 are provided in the gate body 1;

[0026] It should be noted that the gate body 1 is provided with a through opening for the active fan blades 3 to open and close;

[0027] By adopting the above technical solution, when in use, the driving assembly is started to make the active fan blades 3 rotate back and forth, and the driven fan blades 4 are slidably arranged in the active fan blades 3. When the active fan blades 3 rotate, the driven fan blades 4 will automatically slide into the active fan blades 3 under the action of gravity as the active fan blades 3 rotate to a certain angle. The opening and closing of the active fan blades 3 and the driven fan blades 4 cooperate to control the orderly entry and exit of passengers. The two swing protection plates 6 in the gate body 1 can evenly support and guide the active fan blades from both sides when the active fan blades 3 rotate, thereby avoiding abnormal opening and closing of the active fan blades 3 and reducing the wear of a single point on the active fan blades 3.

[0028] Reference Figure 2 The driving assembly includes a cylinder 11, a rack 12, and a gear 13. The cylinder 11 is fixed on the swing protection plate 6. The telescopic end of the cylinder 11 is fixed to the rack 12. The gear 13 is fixed to the rotating shaft 5. The rack 12 and the gear 13 are meshed. A placement groove 14 is opened on the gate body 1, and the gear 13 is located in the placement groove 14.

[0029] By adopting the above technical solution, when the active fan blades 3 need to be opened and closed, the cylinder 11 is started to push the rack 12. Under the meshing action of the rack 12 and the gear 13, the gear 13 drives the rotating shaft 5 to rotate, and the cylinder 11 is extended and retracted, so that the rotating shaft 5 drives the active fan blades 3 to swing back and forth, that is, to open and close.

[0030] Reference Figure 4The driven blade 4 is provided with a slider 10, the active blade 3 is provided with a cavity, and the inner wall of the cavity is provided with a slide groove 9 for the slider 10 to slide;

[0031] It should be noted that the slider 10 passes through the driven fan blade 4, and two slide grooves 9 are provided. The two ends of the slider 10 slide in the two slide grooves 9 respectively, and the slide grooves 9 play a role of limiting and guiding the sliding of the driven fan blade 4.

[0032] By adopting the above technical solution, when the active fan blade 3 rotates to a certain angle, the driven fan blade 4 will slide into or out of the active fan blade 3 along the slide groove 29 under the action of gravity. The setting of the two slide grooves 29 can make the sliding of the driven fan blade 4 smoother, reduce the risk of accidental pinching, and thus protect the passengers when passing through the gate body 1.

[0033] Reference Figure 4 The active fan blade 3 is provided with a slider 8, and the swing protection plate 6 is provided with a slide groove 7 for the slider 8 to slide;

[0034] By adopting the above technical solution, when the active fan blade 3 rotates, the slider 8 slides along the slide groove 7, and the slide groove 7 limits and guides the rotation of the active fan blade 3, so that the swing of the active fan blade 3 is more stable.

[0035] Reference Figure 5 , 7 , a slider 3 16 is provided on the swing protection plate 6, and a slide groove 3 15 for the slider 3 16 to slide is provided on the gate body 1;

[0036] By adopting the above technical solution, the setting of the slide groove three 15 facilitates the disassembly and maintenance of the swing protection plate 6. When the swing protection plate 6 is lifted upward along the vertical direction of the slide groove three 15 to the top of the slide groove three 15, the swing protection plates 6 on both sides are slid toward the support grooves on both sides of the slide groove three 15 respectively, and the swing protection plate 6 can be disassembled.

[0037] Reference Figure 1 , a maintenance door 2 for maintaining the gate body 1 is provided on the gate body 1;

[0038] It should be noted that the maintenance door 2 may be hinged to the gate body 1;

[0039] By adopting the above technical solution, it is convenient to maintain and overhaul the components inside the gate body 1 by opening the maintenance door 2 .

[0040] The implementation principle of a subway entrance and exit gate with a protective structure in an embodiment of the present application is as follows: when a passenger needs to pass through, the cylinder 11 is started, and the cylinder 11 extends to push the rack 12 to drive the gear 13 to rotate, so that the active blades 3 rotate and retract, and the driven blades 4 also retract into the active blades 3 under the action of gravity. At this time, the gate body 1 is opened. After the passenger passes through, the cylinder 11 contracts and pulls the rack 12 to rotate and open the active blades 3, and the driven blades 4 also open accordingly. At this time, the gate body 1 is closed, and this reciprocating process can be repeated. When the active blades 3 continue to rotate, the two swinging protection plates 6 provide uniform support and guidance for the continuously rotating active blades 3, and at the same time, the driven opening and closing of the driven blades 4 cooperates with it, effectively avoiding the situation where passengers are pinched and injured due to abnormal opening and closing of the active blades 3 or the driven blades 4, and has a good protection effect.
