Description

Technical Field

[0001] The utility model relates to the technical field of passenger ground cable cars, in particular to an obstacle detection device for passenger ground cable cars. Background Art

[0002] When a passenger ground cable car (hereinafter referred to as a passenger car) is running on a track line, if there is an obstacle in front of it, it should stop in time to avoid safety accidents. At present, an obstacle detection device is usually installed on the passenger car to detect whether there are obstacles that affect the operation of the passenger car. If an obstacle is detected at the front of the passenger car, a stop signal is triggered.

[0003] Existing detection devices generally use steel components. When an obstacle contacts and bends the steel component, the steel component undergoes structural deformation, triggering a stop signal. However, in this case, the obstacle and the steel component are in rigid contact, and the signal can only be triggered after the steel component undergoes structural deformation, resulting in insufficient detection sensitivity.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Combine the following Figures 1 to 4 The utility model describes an obstacle detection device for a passenger ground cable car.

[0040] like Figures 1 to 4 As shown, the embodiment of the utility model provides an obstacle detection device for a passenger ground cable car, comprising a mounting bracket 1, a moving assembly 2, an elastic member 3, a sensing member 4, and a sensor 5. Specifically, as Figure 1 As shown, the mounting bracket 1 is used to be connected to the body of the bus. The moving component 2 is slidably connected to the mounting bracket 1, and the moving component 2 is used to contact with an obstacle and slide relative to the mounting bracket 1 under the push of the obstacle. Figure 4 As shown, the elastic member 3 is arranged between the moving component 2 and the mounting bracket 1, one end of the elastic member 3 abuts against the moving component 2, and the other end abuts against the mounting bracket 1, and a spring may be selected, for example. The sensing member 4 is connected to the moving component 2, and the sensor 5 is arranged on the mounting bracket 1, and the sensor 5 is used to sense the sensing member 4 and generate a sensing signal.

[0041] like Figure 1 As shown, when the bus is running on the track, if there is an obstacle in front of it, such as a fallen tree, a rolling stone, etc., the moving component 2 will touch the obstacle first, and the obstacle will generate a thrust in the opposite direction. When the thrust reaches a certain value, it will overcome the elastic force of the spring, push the spring to compress and deform, and push the moving component 2 together with the sensing element 4 to move to the left. At this time, the sensing element 4 moves into the sensing range of the sensor 5, so that the sensor 5 is triggered to generate a sensing signal, thereby realizing the detection of the obstacle, triggering the stop signal, and controlling the bus to stop. It should be noted that, as shown in the figure, Figure 1As for the placement position of the obstacle detection device for the passenger ground cable car shown in the figure, the left and right directions in the figure are the left and right directions referred to.

[0042] In this way, by adding an elastic telescopic structure, elastic contact is formed, and the required elastic preload can be determined according to actual use needs, so that obstacles on the track can be detected, and a signal can be triggered to control the bus to stop at a small touch force, thereby improving detection sensitivity, avoiding major collision accidents of the bus, and protecting the safety of passengers. At the same time, due to a certain preload, the mobile component can also remove minor debris such as snow on the track without stopping, which increases the stability of the vehicle operation and does not stop frequently.

[0043] In the embodiment of the present utility model, the moving assembly 2 includes a push plate 21, a connecting frame 22, and a sliding shaft 23. Specifically, Figure 4 As shown, the push plate 21 is used to contact the obstacle, and the connecting frame 22 is connected to the push plate 21. Figure 1 As shown, the connecting frame 22 is configured as a U-shaped connecting frame, and the connecting frame 22 is welded to the push plate 21. The sliding shaft 23 is disposed on the connecting frame 22, and the sliding shaft 23 is slidably connected to the mounting bracket 1. For example, Figure 4 As shown, the sliding shaft 23 is fixedly connected to the connecting frame 22 by a fastening screw, and the sensing member 4 is connected to the sliding shaft 23. In order to facilitate the installation of the fastening screw, the push plate 21 is provided with an avoidance hole 211. In this way, when an obstacle pushes the push plate 21 to move to the left, it will drive the connecting frame 22, the sliding shaft 23 and the sensing member 4 to move together, thereby triggering the sensor 5 to generate a parking signal. It should be noted that, as shown in FIG. Figure 4 As for the placement position of the obstacle detection device for the passenger ground cable car shown in the figure, the left and right directions in the figure are the left and right directions referred to.

[0044] Further, in the embodiment of the present utility model, if Figure 4 As shown, the push plate 21 is tilted. In this way, when the bus is moving forward, the push plate 21 is tilted to one side, so as to facilitate the removal of small debris on the track. Figure 4 As for the placement position of the obstacle detection device for the passenger ground cable car shown in the figure, the direction indicated by the arrow in the figure is the forward direction of the passenger car.

[0045] In an optional embodiment of the present invention, the obstacle detection device for passenger ground cable cars further includes a transition connection seat 6, which is disposed on the mounting bracket 1, for example, by welding. Figure 4As shown, the transition connection seat 6 is provided with a first through hole 61 adapted to the sliding shaft 23, and the sliding shaft 23 is slidably connected in the first through hole 61. The elastic member 3 is sleeved on the sliding shaft 23, and one end of the elastic member 3 abuts against the sliding shaft 23, and the other end abuts against the transition connection seat 6. For example, the sliding shaft 23 is provided with a first step surface 231, and the transition connection seat 6 is provided with a second step surface 62 opposite to the first step surface 231. The elastic member 3 can be a spring, and one end of the spring abuts against the first step surface 231, and the other end abuts against the second step surface 62. Such a configuration provides an installation space for the elastic member 3, which is convenient for assembly.

[0046] Furthermore, in the embodiment of the utility model, the obstacle detection device for passenger ground cable car further comprises a guide sleeve 7, the guide sleeve 7 is slidably connected to the mounting bracket 1, and the guide sleeve 7 is connected to the connecting frame 22. For example, the guide sleeve 7 is connected to the connecting frame 22 via a fixing member 8. Specifically, Figure 4 As shown, the fixing member 8 is a screw adapted to the guide sleeve 7, which passes through the guide sleeve 7 and is threadedly connected to the connecting frame 22, and then fastened with a nut. In addition, a retaining ring 30 is provided, which can be abutted against the mounting bracket 1 to further limit and fix the guide sleeve 7. Such an arrangement can play a guiding role and ensure that the movement of the mobile component 2 is more stable and reliable. In addition, guide sleeves 7 and the like can be arranged on both sides of the connecting frame 22 to improve the movement stability of the mobile component 2. It can be understood that the length of the guide sleeve 7 can be specifically set according to the range of motion of the mobile component 2.

[0047] As an optional embodiment of the utility model, the obstacle detection device for passenger ground cable car further includes a sliding bearing 9, which is arranged in the first through hole 61 and is located between the sliding shaft 23 and the transition connection seat 6. Specifically, Figure 4 As shown, the sliding bearing 9 can be a flanged sliding bearing, so that the sliding bearing 9 can be easily fixed, for example, by bolts. This arrangement reduces the movement resistance of the sliding shaft 23, ensures that the sliding of the moving assembly 2 is more flexible and smooth, and thus improves the control of the thrust size. In addition, sliding bearings 9 are arranged at both ends of the transition connection seat 6, and a countersunk hole is provided at the right end of the transition connection seat 6 to prevent the bolt head from protruding from the connection seat surface.

[0048] In a specific embodiment of the present invention, the obstacle detection device for a passenger ground cable car further includes a connecting shaft 10 and a stopper 20. Specifically, Figure 4As shown, the connecting shaft 10 is connected to the sliding shaft 23, for example, by threaded connection. The sensing member 4 is provided with a second through hole adapted to the connecting shaft 10, and the connecting shaft 10 is slidably connected in the second through hole. The limiting member 20 is sleeved on the connecting shaft 10, and the limiting member 20 is used to prevent the sensing member 4 from continuing to move relative to the connecting shaft 10. For example, the limiting member 20 can use a nut, and the connecting shaft 10 is provided with an external thread adapted to the nut. In addition, a double nut anti-loosening structure can be used to ensure reliable fixation. Such a configuration makes it easy to install the sensing member 4, and it is convenient to adjust the installation position of the sensing member 4 to ensure that the sensing member 4 can trigger the sensor 5. After adjusting the position of the sensing member 4, the sensing member 4 can be fixed by the limiting member 20, which is convenient to operate.

[0049] In an optional embodiment of the present invention, the sensor 5 is configured as a contact sensor, and the sensing member 4 is provided with an inclined contact portion 41 adapted to the sensor 5. For example, the sensor 5 may be a travel switch, such as a cam travel switch. Figure 1 As shown, under the push of the obstacle, the sensing member 4 moves to the left, and the inclined contact portion 41 on the sensing member 4 first touches the cam travel switch and triggers the parking signal. This is simple to operate and reliable to use. The inclined contact portion 41 can ensure that the sensing member 4 can smoothly trigger the travel switch. In addition, both ends of the sensing member 4 are provided with inclined contact portions 41, so that when the sensor 4 moves over the position under the push of the obstacle, it can also smoothly disengage from the travel switch to prevent damage to the travel switch.

[0050] As an optional embodiment of the present utility model, Figure 1 As shown, the mounting bracket 1 includes a first connecting plate 11 and a second connecting plate 12 that are spaced apart. The first connecting plate 11 is used to connect the vehicle body, and the second connecting plate 12 is slidably connected to the moving component 2. The connecting rib 13 is disposed between the first connecting plate 11 and the second connecting plate 12, and can be connected by welding, for example. The sensor 5 is disposed on the connecting rib 13, and can be connected by bolts, for example. In this way, a mounting bracket 1 with a stable structure is formed, and sufficient assembly layout space is provided to facilitate the installation and disassembly of various components. In addition, as Figure 2 and Figure 3 As shown, the number of the connecting ribs 13 is at least two, which can further improve the structural strength of the mounting bracket 1.

[0051] In a specific embodiment of the present invention, Figure 2 As shown, the first connecting plate 11 is provided with a third through hole 111 for connecting to the vehicle body, and the third through hole 111 is set as a waist-shaped hole. Among them, the number and position of the third through holes 111 can be specifically determined according to actual use requirements. With such a configuration, the entire device can be installed on the bus by inserting fasteners, and by setting the waist-shaped hole, it is convenient to adjust the installation height to ensure that the lower edge of the push plate 21 has a suitable distance from the upper surface of the track. It should be noted that, as shown in Figure 1 and Figure 2 For the placement position of the obstacle detection device for the passenger ground cable car shown in the figure, the up and down directions in the figure refer to the up and down positions and height directions.
