Description

Technical Field

[0001] The present invention belongs to the technical field of trams, and more particularly, relates to an anti-rollover safety system and a tram comprising the anti-rollover safety system. Background Art

[0002] At present, with the increase of urban rail transit projects, the demand for modern tram vehicles has greatly increased. Trams can not only alleviate urban traffic congestion, but also help save oil resources, are pollution-free and environmentally friendly. Compared with subways, the construction investment per kilometer is 1 / 3-1 / 5 of that of subways, the construction period is only 1 / 2-1 / 3 of that of subways, and the operating cost is only about 1 / 2 of that of buses. Therefore, modern trams have great room for future development. In addition, many manufacturers have proposed many models, and different models are equipped with different vehicle appearance designs, but none of them are designed with anti-rolling devices, which are very vulnerable to damage in dangerous situations.

[0003] In the prior art, only the appearance modeling and skirt decoration are done in the structure of the tram, and no anti-rolling device is used, which cannot prevent children and foreign objects from being rolled into the bottom of the vehicle.

[0004] In addition, traditional vehicles are basically not equipped with entrapment protection devices. Once a traffic accident occurs with pedestrians, animals or foreign objects at intersections, pedestrians or other objects are very likely to be entrapped under the vehicle. On the one hand, the floor height of the low-floor tram itself is about 400mm, and if the vehicle hits a person and entraps him, it will cause life-threatening injuries. On the other hand, if the foreign object is strong, it is easy to cause serious damage to the vehicle, and even more seriously, it can cause the vehicle to derail or overturn, affecting public transportation safety.

[0005] Therefore, it is desirable to design an anti-rollover safety system and a tram that overcome the above-mentioned defects. Summary of the invention

[0006] In view of the existing technical solutions and in order to adapt to development needs, the present invention designs an anti-entrapment safety system to adapt to the safe operation of new modern trams and solve the safety problem of people, animals or foreign objects being entrapped under the tram when an accident occurs.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The monitoring camera is connected to a status display and video monitoring device and communicates with the status display and video monitoring device to display and monitor the status of the protection net, limit sensor, power supply module and electromagnetic locking device on the status display and video monitoring device.

[0017] In one embodiment of the present invention, the anti-entanglement safety system further comprises:

[0018] a foreign body entanglement triggering device, the foreign body entanglement triggering device being communicatively connected to the foreign body entanglement protection device;

[0021] In one embodiment of the present invention, the electromagnetic locking device includes a first electromagnetic locking device and a second electromagnetic locking device, and the first electromagnetic locking device and the second electromagnetic locking device are respectively connected to the foreign matter entanglement protection device.

[0022] In one embodiment of the present invention, when the limit sensor generates an erroneous trigger signal, which causes the protective net to be unable to be opened, the electric control device switches from the automatic mode to the manual mode.

[0023] In one embodiment of the present invention, when the electric control device operates in the automatic mode, the limit sensor is triggered to achieve automatic descent of the protection net of the foreign object entanglement protection device.

[0036] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are only illustrative. Although only a few embodiments are described in detail in the present invention, it is easy for those skilled in the art to appreciate that multiple modifications are feasible without actually departing from the teaching of the subject matter of the present invention. Accordingly, all such modifications should be included within the scope of the present invention. Without departing from the gist of the present invention, other replacements, modifications, changes and deletions may be made to the design, operating conditions and parameters of the following exemplary embodiments.

[0037] like Figure 1 As shown, an anti-entrapment safety system includes: a foreign body entrapment protection device, an electric control device, a manual controller, a state display and video monitoring device, a protection net, a first limit sensor and a second limit sensor, a power supply module, a first electromagnetic locking device and a second electromagnetic locking device, and a monitoring camera. The electric control device is connected to the state display and video monitoring device, and the electric control device is connected to the foreign body entrapment protection device and drives the foreign body entrapment protection device, and the electric control device can switch between manual mode and automatic mode; the manual controller is connected to the electric control device; the protection net is connected to the foreign body entrapment protection device; the first limit sensor and the second limit sensor are respectively connected to the foreign body entrapment protection device in a communication manner; the power supply module is connected to the foreign body entrapment protection device; the first electromagnetic locking device and the second electromagnetic locking device are respectively connected to the foreign body entrapment protection device; the monitoring camera is connected to the foreign body entrapment protection device in a communication manner, and the monitoring camera is connected to the state display and video monitoring device and communicates with the state display and video monitoring device to display and monitor the state of the protection net, the limit sensor, the power supply module and the electromagnetic locking device on the state display and video monitoring device.

[0038] Through the above technical scheme of the present invention, the present invention can ensure the normal operation of tram vehicles, and can effectively reduce injuries and driving risks once involvement occurs. The system of the present invention realizes two separate control modes, automatic and manual, and realizes automatic protection, status display and monitoring of the system, thus providing better protection for vehicle operation.

[0039] In the above technical solution, the anti-entanglement safety system also includes: a foreign object entanglement trigger device and a pulley, the foreign object entanglement trigger device is communicatively connected to the foreign object entanglement protection device; the pulley is arranged on the protection net.

[0040] In the above technical solution, when a trigger signal error occurs in the limit sensor and the protective net cannot be opened, the electric control device switches from the automatic mode to the manual mode.

[0041] In the above technical solution, when the electric control device operates in the automatic mode, the limit sensor is triggered to realize the automatic descent of the protection net of the foreign object entangled protection device.

[0042] In the above technical solution, when the electric control device is operated in the manual mode, the manual controller is used to trigger the electromagnetic locking device to control the descent of the protection net.

[0043] In the above technical solution, there is a logical interlock between the foreign object entanglement protection device and the vehicle traction braking system.

[0044] In addition, the present invention also provides a tram, comprising the anti-rollover safety system as described above.

[0045] In the above technical solution, the anti-roll-in safety system is installed below the head of the cab of the tram.

[0046] Reference Figure 2 , Figure 2 FIG. 2 shows a schematic diagram of the above anti-rollover safety system installed on a tram. Figure 2 As shown, the anti-rollover safety system is installed below the cab head 8 of the tram, wherein the front view and top view structures of the cab head 8 of the tram are respectively as shown in FIG. Figure 2 and 3 As shown. In the installed anti-entrapment safety system, when there is no foreign matter, the tram runs normally, the protection net 7 of the foreign matter entrapment protection device 1 is in the raised position, the status display and video monitoring equipment show that all components are operating normally, and the protection net 7 in the raised position can be displayed and monitored through the monitoring camera 4; when there is a foreign matter and the foreign matter collides with the foreign matter entrapment trigger device 5, an electric signal is sent to the electric control device, so that the protection net 7 of the foreign matter entrapment protection device 1 can be lowered, wherein a pulley 6 is provided on the protection net 7, and the pulley 6 is triggered when there is a foreign matter or a person in the tram, and the protection net 7 is lowered. Since the tram is decelerating, the pulley 6 provides sliding support for the protection net 7 at this time. After the protection net 7 is lowered, the protection net 7 prevents foreign matter from being drawn into the bottom of the tram, and the status display and video monitoring equipment can display and monitor the status of the protection net 7 at this time through the monitoring camera 4.

[0047] Preferably, the electric control device is divided into automatic and manual modes. The operation of the automatic mode is that after the foreign object collides with the foreign object entanglement trigger device 5, the connecting rod is displaced, triggering the limit sensor 2, and sending an electrical signal to the electric control device, which can realize the automatic descent of the protection net 7 of the foreign object entanglement protection device 1, thereby realizing protection. At the same time, the status display and video monitoring equipment can display its status. And the status display and video monitoring equipment can intuitively monitor the operating status of each component and playback the video through the monitoring camera 4 for easy inspection. In the manual mode, the electromagnetic locking device 3 can be triggered by the trigger button on the console or the manual controller to control the descent of the protection net 7, which is operated separately.

[0048] In addition, for safety reasons, there is a logical interlock between the foreign body entanglement protection device 1 and the vehicle traction brake system. In order to ensure that the protection net opens normally and prevent the protection net 7 from being unable to open due to an erroneous trigger signal caused by the limit switch, a manual control button or manual controller is set on the control panel, that is, after pressing the control button or manual controller, the electromagnetic locking device 3 will be triggered to ensure that the system works normally and plays a protective role.

[0049] To sum up, the newly developed foreign object anti-entanglement system with automatic and manual control functions of the present invention can realize foreign object detection and provide safety protection through a protective net, can adapt to control needs in different situations, and has automatic protection function, status display function, etc., which is more suitable for actual working conditions. Moreover, the present invention has also achieved good results in practical applications and obtained satisfactory responses from owners. It can be continued to be promoted in future projects and has good economic benefits.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, it should be included in the protection scope of the claims of the present invention.
