Description

Technical Field

[0001] The utility model belongs to the field of electric fence doors, and in particular relates to an electric fence door barrier at a railway crossing. Background Art

[0002] A railway crossing is the intersection of the road and the railway plane, and can be divided into manned crossings and unmanned crossings.

[0003] Normally, manned crossings are equipped with railway crossing signals and safety protection equipment such as telephones, wireless intercoms, crossing signals, barrier machines and approach sensors in accordance with standard regulations. The crossings are closed / opened under the operation and management of the crossing workers, and the safety of road vehicles and pedestrians and the smooth passage of trains through the crossings are manually ensured.

[0004] With the improvement of intelligence, railway crossings have gradually changed from manned crossings to unmanned crossings. However, unmanned railway crossings are still very dangerous even if they are equipped with safety protection facilities such as crossing signals and warning signs. In addition, the current unmanned crossings are generally monitored and remotely controlled by the centralized control center to open and close the electric fence gates, and collisions between the remotely controlled gates and pedestrians or vehicles often occur.

[0005] Especially in metallurgical enterprise plants, due to the particularity of the plant, it is necessary to frequently use railways for the transportation of goods. Therefore, there are many intersections of railways and roads. There are many workers in the plant, and the site conditions are relatively complicated. The gates controlled by remote control cannot respond in time. If they encounter foreign objects blocking them or people forcing them, they will not stop automatically, resulting in frequent collisions and accidents that injure pedestrians.

[0006] And because there is no one to guard the electric fence gate, no one cleans the track surface or track groove. Once there is a lot of debris or garbage, the electric fence gate is easy to derail and malfunction, and cannot continue to work. And when the power supply of the fence gate is cut off or disconnected from the control center, the electric fence gate cannot work. The electric fence gate is not a lighter blocking device such as an electric gear lever. The electric fence gate is heavy as a whole and it is difficult to move by manpower. Although people can climb over the fence gate to move, vehicles cannot pass.

[0007] Therefore, a new design that is more suitable for remote control is needed. Utility Model Content

[0008] In view of the above problems existing in the prior art, the purpose of the utility model is to provide an electric fence gate barrier at a railway crossing.

[0009] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0010] An electric barrier gate at a railway crossing comprises a barrier gate and a collision reaction component, wherein the collision reaction component comprises a collision sensing plate and a response switch, wherein the response switch comprises a base, a guide tube, a tension spring and a travel switch, wherein a guide rod is arranged on the collision sensing plate, wherein the guide rod passes through the guide tube and is connected to the base, wherein the end of the guide rod is connected to the tension spring, wherein the other end of the tension spring is connected to the base, and wherein a travel switch is arranged between the base and the collision sensing plate.

[0011] The response switches are provided with two, one above and one below, which are arranged at the ends of the fence gate.

[0012] The cross section of the fence door is a square frame.

[0013] The response switches are symmetrically arranged on both sides of the end of the fence gate.

[0014] The collision sensing plate is a U-shaped structure, and two sides of the collision sensing plate are respectively connected to symmetrically arranged response switches.

[0015] The bottom of the end of the fence door is provided with an obstacle removal shovel.

[0016] Debris collecting pits are arranged on the left and right sides of the fence door.

[0017] The fence door is provided with a storage battery.

[0018] The outer side of the fence door is provided with an audible and visual alarm device.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The utility model is mainly aimed at improving the unmanned electric fence gate at the railway crossing, and strengthens its various functions in the unmanned situation. Compared with the fence gates in the prior art, the fence gate has the advantages of anti-collision, anti-crushing of pedestrians, automatic stop when there are people or vehicles on the walking track, and continuous sound and light alarm after power failure or tripping by battery power. It also has the advantages of reflective strips on the door body, cleaning of debris and foreign objects in the track and track groove, and prevention of derailment.

[0024] The utility model is further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown, the utility model is mainly based on the improvement of the electric fence door at the railway crossing.

[0026] The main body of the utility model is an electrically controlled movable fence door 1, at the end of which a collision reaction component is arranged, and the collision reaction component mainly comprises a collision sensing plate 2 and a response switch.

[0027] The specific structure of the response switch is as follows Figure 2 As shown, the part connected to the fence gate 1 is the base 3, a guide tube 4 is arranged at the center of the base 3, and a tension spring baffle 7 is arranged at one end of the guide tube 4 facing the inner side of the fence gate 1. Tension springs 5 ​​are arranged at the upper and lower sides of the guide tube 4, one end of the two tension springs 5 ​​is connected to the base 3, and the other end is connected to the tension spring baffle 7. A travel switch 6 is arranged on one side of the base 3 close to the end of the fence gate, and the travel switch 6 is also arranged one above and one below with the guide tube 4 as the center.

[0028] A guide rod 8 is provided on the collision sensing plate 2 . The guide rod 8 passes through the guide tube 4 and is connected to the tension spring baffle 7 . Two protrusions matching the travel switch 6 are provided on the upper and lower sides of the guide rod 8 .

[0029] When the collision sensing plate 2 collides with an obstacle, it will move toward the inner side of the fence gate 1. Under the action of the guide tube 4 and the guide rod 8, the collision sensing plate 2 will move inward along a predetermined route. At this time, the protrusions on the upper and lower sides of the guide rod 8 will push the travel switch 6.

[0030] The cross-section of the fence gate 1 is a square frame, and the length of the collision sensing plate 2 is almost the same as the height of the fence gate 1. Therefore, in order to better respond to the collision sensing plate 2, two response switches are provided, one above and one below, which are respectively connected to the collision sensing plate 2.

[0031] In order to sense obstacles in a wider range, the overall shape of the collision sensing plate 2 is U-shaped. The left and right sides and the bottom of the cross section of the fence door 1 are covered by the collision sensing plate 2. Therefore, the response switch is also symmetrically arranged on the left and right sides of the cross section of the fence door 1, and is respectively connected to the two vertical plates of the collision sensing plate 2. The specific structure is as follows: Figure 1 shown.

[0032] In addition to the sensing components, many alarm devices are arranged on the outer side of the fence gate 1, such as light strips, reflective strips, sound and light alarm devices, etc., which are connected to the travel switch 6 in the response switch. When the travel switch 6 is pushed by the collision sensing plate 2, the alarm device will be interlocked to alarm and stop the fence gate 1 from moving further. Since there are many types of alarm devices and the installation position is relatively free, the type and installation position of the alarm device are not limited in this embodiment, and the devices that can be linked with the travel switch 6 and generate an alarm effect should all fall into the protection scope.

[0033] An obstacle clearing shovel is also provided at the bottom of the end of the fence gate 1, which can push obstacles on the path of the fence gate 1 to the debris collection pits set in advance on the left and right sides to prevent the fence gate 1 from being blocked by obstacles and unable to move further or the rollers at the bottom of the fence gate 1 from derailing.

[0034] Normally, the fence gate 1 is powered directly by the lines within the park. However, due to unattended operation, once the power supply area at the railway crossing is out of power or tripped, the fence gate 1 cannot work and alarm normally. Therefore, a battery is also provided on the fence gate 1, which can still work for a period of time after power failure, and the linkage alarm device sends out an alarm of power failure to remind the staff to carry out maintenance immediately.
