Description

Technical Field

[0001] This utility model belongs to the field of subway safety technology, and in particular relates to a protective device that makes it easier for drivers to detect people or objects caught in gaps. Background Technology

[0002] A subway is an urban rail transit system that typically operates underground. It features high capacity, high speed, punctuality, and environmental friendliness, making it an important component of modern urban public transportation. Due to its high capacity and speed, subway safety measures are a crucial part of subway operation. Subway safety can be mainly divided into four parts: train operation safety, passenger safety, equipment safety, and public safety. To ensure train operation safety, safety protection measures such as signaling systems, speed limits, and driver monitoring are usually adopted. The gap between the train and the platform is an important part of driver monitoring. It is mainly used to prevent foreign objects from being trapped in the gap between the train and the platform and affecting the safety of train operation. Since the train is long, in order to monitor and protect the gap between the train and the platform in all aspects, laser emitters and laser receivers are usually used. By monitoring whether the laser is interrupted, it can be determined whether people or objects are trapped in the gap. However, during use, the laser emitter and receiver are usually directly installed on the train body. While the train is in motion, the laser emitter and receiver are exposed to the air, which not only affects the train's speed but also makes them susceptible to damage from external factors. In addition, the installation height of the laser emitter and receiver on the train body is fixed, and the gap between the train and the platform is quite deep, making it impossible for the laser to monitor different depths of the gap.

[0003] To address this issue, we provide a protective device that helps drivers detect gaps that could trap people or objects, thus resolving the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a protective device that facilitates drivers in detecting people or objects trapped in gaps. A first electric push rod drives a moving block, which in turn moves an L-shaped frame and a U-shaped frame, allowing the detection structure within the U-shaped frame to move to the bottom of the train car. This solves the problem of existing devices where the detection structure is easily damaged by external factors during train travel. Simultaneously, a second electric push rod drives a mounting block to rise and fall, which in turn moves a laser emitter and laser receiver, addressing the difficulty in detecting different depths within the gap between the train car and the platform.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a protective device that facilitates drivers to detect people or objects caught in gaps. It includes a U-shaped frame and a train carriage. The U-shaped frame is installed on the train carriage via a storage assembly. The storage assembly includes a mounting frame fixedly connected to the bottom of the train carriage. A first electric push rod is fixedly connected to one outer wall of the mounting frame. The output shaft of the first electric push rod extends into the interior of the mounting frame and is fixedly connected to a moving block. An L-shaped frame is fixedly connected to the bottom of the moving block. The U-shaped frame is fixedly connected to the vertical support arm of the L-shaped frame. A detection assembly is also provided inside the U-shaped frame. The detection assembly includes a second electric push rod fixedly connected to the bottom of the U-shaped frame. The output shaft of the second electric push rod extends into the inner side of the U-shaped frame and is fixedly connected to the mounting block. A laser emitter and a laser receiver are fixedly connected to the front and rear end faces of the mounting block, respectively.

[0006] A further feature of this invention is that a protective frame is fixedly connected to the outer wall of the U-shaped frame away from the L-shaped frame, and a first infrared ranging sensor is fixedly connected inside the protective frame.

[0007] A further feature of this invention is that L-shaped plates are fixedly connected to both sides of the front and rear end faces of the mounting frame, and the longitudinal support arms of the L-shaped plates are fixedly connected to the bottom of the train carriage.

[0008] A further feature of this invention is that an installation rod passes through the end face of the movable block, and both ends of the installation rod pass through the sliding grooves located on the front and rear end faces of the mounting frame and are threadedly connected with fastening nuts, which are respectively attached to the front and rear end faces of the mounting frame.

[0009] A further feature of this invention is that a mounting plate is fixedly connected to the upper part of one side of the outer wall of the mounting block, and a second infrared ranging sensor is fixedly connected to the lower surface of the mounting plate.

[0010] A further feature of this invention is that: a first fixing frame is fixedly connected to both the front and rear ends of the outer wall on the other side of the mounting block; a second fixing frame is movably connected to the side of the first fixing frame away from the mounting block via a slider; and the second fixing frame is fixedly connected to the inner wall on one side of the U-shaped frame.

[0011] A further feature of this invention is that a first sliding rod is fixedly connected vertically inside the first fixed frame, and a second sliding rod is fixedly connected vertically inside the second fixed frame, with the two ends of the slider respectively slidably sleeved on the first and second sliding rods.

[0012] A further feature of this invention is that: a fixing plate is fixedly connected above and below each of the adjacent first fixing frames and the adjacent second fixing frames, and one outer wall of the fixing plate is fixedly connected to the other outer wall of the mounting block and one inner wall of the U-shaped frame.

[0013] This utility model has the following beneficial effects: 1. This utility model, by setting up a storage component, allows the first electric push rod to be activated when the train car stops. The output shaft of the first electric push rod applies an external force to the moving block, causing the moving block to move out from the bottom of the train car via the L-shaped frame, driving the U-shaped frame and the detection structure. The detection structure inside the U-shaped frame detects whether there are people or objects trapped in the gap between the train car and the platform. This facilitates the storage of the U-shaped frame and the detection structure, preventing the presence of the U-shaped frame and the detection structure from affecting the train speed during operation, and also preventing the U-shaped frame and the detection structure from being damaged by external factors during operation.

[0014] 2. This utility model, by setting up a detection component, activates a second electric push rod. The output shaft of the second electric push rod drives the mounting block to rise and fall. The mounting block drives the laser emitter and laser receiver to rise and fall synchronously, thereby enabling the laser emitter and laser receiver to perform laser emission and reception at different depths within the gap between the train car and the platform. This achieves the monitoring of people and objects trapped at different depths within the gap, facilitating the monitoring of people and objects trapped at different depths within the gap between the train car and the platform, expanding its detection range, and improving its safety.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this is the first embodiment of the present invention. This embodiment provides a protective device that facilitates the driver's detection of people or objects caught in gaps. It includes a U-shaped frame 1 and a train carriage 4. The U-shaped frame 1 is mounted on the train carriage 4 via a storage assembly 2. The storage assembly 2 includes a mounting frame 201, a first electric push rod 202, a moving block 203, and an L-shaped frame 204. The first electric push rod 202 drives the moving block 203 to move, and the moving block 203 drives the L-shaped frame 204 and the U-shaped frame 1 to move. This allows the U-shaped frame 1 and the detection structure inside the U-shaped frame 1 to move to the bottom of the train carriage 4, solving the problem that existing devices are difficult to prevent the detection structure from being damaged by external factors during the operation of the train carriage 4.

[0027] Specifically, the mounting frame 201 is fixedly connected to the bottom of the train car 4. A first electric push rod 202 is fixedly connected to one outer wall of the mounting frame 201. The output shaft of the first electric push rod 202 extends into the interior of the mounting frame 201 and is fixedly connected to a moving block 203. An L-shaped frame 204 is fixedly connected to the bottom of the moving block 203. A U-shaped frame 1 is fixedly connected to the vertical support arm of the L-shaped frame 204. The mounting frame 201 is used to install the first electric push rod 202 and other structures at the bottom of the train car 4. The first electric push rod 202 is used to drive the moving block 203 to move. The moving block 203 is used to drive the L-shaped frame 204 to move. The L-shaped frame 204 is used to install the U-shaped frame 1 and drive the U-shaped frame 1 and the detection structure inside the U-shaped frame 1 to move, so that the U-shaped frame 1 and the detection structure are stored at the bottom of the train car 4 during the train car 4's operation.

[0028] Furthermore, a protective frame 101 is fixedly connected to the outer wall of the U-shaped frame 1 on the side away from the L-shaped frame 204. A first infrared ranging sensor 102 is fixedly connected inside the protective frame 101. The protective frame 101 is set to protect the first infrared ranging sensor 102. The first infrared ranging sensor 102 is set to detect the distance between the U-shaped frame 1 and the platform. Both sides of the front and rear ends of the mounting frame 201 are fixedly connected to L-shaped plates 201a. The longitudinal support arm of the L-shaped plate 201a is fixedly connected to the bottom of the train car 4. The L-shaped plate 201a is used to fix the mounting frame 201 to the bottom of the train car 4 with bolts. A mounting rod 203a passes through the end face of the movable block 203. Both ends of the mounting rod 203a pass through the sliding grooves 201b located on the front and rear end faces of the mounting frame 201 and are threadedly connected to fastening nuts 203b. The fastening nuts 203b are respectively attached to the front and rear end faces of the mounting frame 201. The sliding grooves 201b and the mounting rod 203a enable the movable block 203 to be movably installed inside the mounting frame 201. The fastening nuts 203b are used to install the mounting rod 203a on the movable block 203.

[0029] The operation process of this embodiment is as follows: When the train carriage 4 stops, the first electric push rod 202 is activated. The output shaft of the first electric push rod 202 applies an external force to the moving block 203, so that the moving block 203 drives the U-shaped frame 1 and the detection structure to move out from the bottom of the train carriage 4 through the L-shaped frame 204. The detection structure in the U-shaped frame 1 is used to detect whether there are people or objects trapped in the gap between the train carriage 4 and the platform.

[0030] Example 2 Please see Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: a detection component 3 is also provided inside the U-shaped frame 1. The detection component 3 includes a second electric push rod 301, a mounting block 302, a laser emitter 303, and a laser receiver 304. The second electric push rod 301 drives the mounting block 302 to rise and fall, and the mounting block 302 drives the laser emitter 303 and the laser receiver 304 to rise and fall, thus solving the problem that it is inconvenient to detect different depths in the gap between the train carriage 4 and the platform.

[0031] Specifically, the second electric push rod 301 is fixedly connected to the bottom of the U-shaped frame 1. The output shaft of the second electric push rod 301 extends to the inner side of the U-shaped frame 1 and is fixedly connected to the mounting block 302. The front and rear end faces of the mounting block 302 are respectively fixedly connected to the laser emitter 303 and the laser receiver 304. The second electric push rod 301 is used to drive the mounting block 302 to rise and fall. The mounting block 302 is used to install the laser emitter 303 and the laser receiver 304 and drive them to rise and fall. The laser emitter 303 is used to emit laser light, and the laser receiver 304 is used to receive laser light. When the laser receiver 304 does not receive laser light, it means that there is a person or object trapped in the gap between the train carriage 4 and the platform.

[0032] Furthermore, an mounting plate 302a is fixedly connected to the upper part of one side outer wall of the mounting block 302, and a second infrared ranging sensor 302b is fixedly connected to the lower surface of the mounting plate 302a. The second infrared ranging sensor 302b is set to detect the height of the mounting block 302 in real time. The front and rear ends of the other outer wall of the mounting block 302 are fixedly connected to the first fixing frame 305. The side of the first fixing frame 305 away from the mounting block 302 is movably connected to the second fixing frame 307 through the slider 306. The second fixing frame 307 is fixedly connected to the inner wall of one side of the U-shaped frame 1. The arrangement of the first fixing frame 305 and the second fixing frame 307 makes the movement of the mounting block 302 relative to the U-shaped frame 1 more stable. The slider 306 realizes the movable connection between the first fixing frame 305 and the second fixing frame 307. A first slide rod 305a is fixedly connected vertically inside the first fixed frame 305, and a second slide rod 307a is fixedly connected vertically inside the second fixed frame 307. The two ends of the slider 306 are slidably sleeved on the first slide rod 305a and the second slide rod 307a respectively. The arrangement of the first slide rod 305a and the second slide rod 307a realizes the movable connection between the slider 306 and the first fixed frame 305 and the second fixed frame 307. Fixing plates 305b are fixedly connected above and below each other between adjacent first fixing frames 305 and adjacent second fixing frames 307. The outer wall of one side of the fixing plate 305b is fixedly connected to the outer wall of the mounting block 302 and the inner wall of the U-shaped frame 1. The fixing plates 305b are used to install the first fixing frames 305 and the second fixing frames 307 on the mounting block 302 and the U-shaped frame 1 respectively.

[0033] The rest of the structure is the same as in Example 1.

[0034] The operation process of this embodiment is as follows: the second electric push rod 301 is activated, and the output shaft of the second electric push rod 301 drives the mounting block 302 to rise and fall. The mounting block 302 drives the laser emitter 303 and the laser receiver 304 to rise and fall synchronously, so that the laser emitter 303 and the laser receiver 304 can perform laser emission and laser reception at different depths in the gap between the train carriage 4 and the platform, thereby realizing the monitoring of people and objects being clamped at different depths in the gap.
