Description

Technical Field

[0001] This application relates to the field of rail-powered electric vehicle technology, and in particular to a rail-powered electric vehicle anti-runaway device. Background Technology

[0002] In rail transit engineering construction, electric vehicles inside tunnels are mainly used to transport excavated soil and related construction materials. They can efficiently and quickly transport materials to various work faces inside the tunnel, reducing the time and labor intensity of manual handling. They are also used for rapid response in emergency situations, such as transporting rescue equipment, medical supplies, or evacuating personnel.

[0003] However, within tunnels used for rail transit construction, factors such as slippery conditions, mud, water accumulation, excessive wear or damage to brake pads, electrical system malfunctions, and insufficient maintenance can lead to reduced braking effectiveness or brake failure. For long-distance, steeply gradient tunnels, brake failure in electric vehicles poses a serious safety hazard, potentially resulting in accidents or injuries.

[0004] Although drivers can try to slow down and stop using the backup braking system or terrain conditions, the existing backup braking system is slow to respond and unreliable under complex working conditions such as long distances and steep slopes, making it difficult to perform emergency braking and thus unable to effectively ensure construction safety.

[0038] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0044] See Figure 1-5 A track-mounted battery vehicle anti-slip device includes: a connecting box 1, a ground-mounted stop 2, and a telescopic cylinder 3.

[0045] The connecting box 1 has a stop through hole 101 inside, and a support plate 102 is provided on the top walls on both sides of the stop through hole 101.

[0046] The front end of the connecting box 1 is provided with two first connecting plates 103 spaced apart, and a first connecting through hole 1031 is provided on the first connecting plate 103. Inside the connecting box 1, there are two second connecting plates 104 spaced apart, and a second connecting through hole 1041 is provided on each of the second connecting plates 104.

[0047] In this embodiment, by providing a first connecting plate 103 on the connecting box 1, the connecting box 1 can be easily fixed to the rail battery car by means of bolts or pins. At the same time, by providing a second connecting plate 104, it can be easily connected and fixed to the first connecting plate 103 by means of bolts or pins, so as to realize the connection and fixation between different rail battery cars.

[0048] A mounting bracket 105 is provided on the top of the upper first connecting plate 103, and the telescopic cylinder 3 is mounted on the mounting bracket 105.

[0049] The floor-mounted stop 2 has a telescopic rod through hole 201 on its upper part, and limit stops 202 are provided on both sides of the floor-mounted stop 2. The floor-mounted stop 2 is mainly composed of a 10cm thick steel plate with dimensions of 80cm*30cm.

[0050] In this embodiment, by passing the telescopic rod on the telescopic cylinder 3 through the telescopic rod through hole 201 of the ground-mounted stop 2, the ground-mounted stop 2 can be fixedly hoisted in the stop hole 101 of the connecting box 1. When the railcar slips, the telescopic rod is retracted by controlling the telescopic cylinder 3, and the ground-mounted stop 2 falls by its own weight. After the ground-mounted stop 2 falls, it can effectively lock the sleeper and will be locked in the stop hole 101 due to the limit stop, so as to provide resistance to stop the railcar, effectively improving the response efficiency and safety in emergency situations.

[0051] Specifically: The mounting bracket 105 is provided with a positioning baffle 1051.

[0052] In this embodiment, by setting the positioning baffle 1051, the position of the telescopic cylinder 3 on the mounting bracket 105 can be ensured to be stable and accurate, preventing it from shifting or loosening during operation.

[0053] Specifically: the top of the floor-mounted stop 2 is provided with a stop lug 203; the two sides of the connecting box 1 are provided with box lugs 106.

[0054] In this embodiment, the block lug 203 and the box lug 106 are provided to provide hoisting and fixing points, which facilitates the installation and fixing of the floor-mounted block 2 and the connecting box 1, thereby enhancing the stability and safety of the floor-mounted block 2 in the connecting box 1.

[0055] Specifically, the top of the support plate 102 is provided with an arc-shaped notch 1021.

[0056] In this embodiment, by setting the arc-shaped notch 1021, a smooth movement path and better support can be provided for the telescopic pole, reducing friction and the risk of jamming.

[0057] Specifically: the anti-slip device for the track-mounted electric vehicle also includes: controller 4;

[0058] The telescopic cylinder 3 is a pneumatic telescopic cylinder 3. The pneumatic telescopic cylinder 3 is connected to the air source of the electric vehicle air compressor through an air pipe. A solenoid valve 5 is installed in the air pipe. The controller 4 establishes an electrical connection with the solenoid valve 5. By driving the solenoid valve 5 to act, the controller controls the opening and closing of the air passage of the pneumatic telescopic cylinder 3.

[0059] In this embodiment, by setting a controller 4, the controller 4 drives the solenoid valve 5 through an electrical signal to quickly switch the air circuit on and off, thereby controlling the extension and retraction of the pneumatic telescopic cylinder 3, which can improve the response speed and operation convenience of the anti-slip device.

[0060] The technical solution provided in this application may include the following beneficial effects:

[0061] This application achieves this by passing the telescopic rod on the telescopic cylinder 3 through the telescopic rod through hole 201 of the ground-mounted stop 2, which can fix the ground-mounted stop 2 in the stop hole 101 of the connecting box 1. When the railcar slips, the telescopic rod is retracted by controlling the telescopic cylinder 3, and the ground-mounted stop 2 falls by its own weight. After the ground-mounted stop 2 falls, it can effectively lock the sleeper and will be locked in the stop hole 101 due to the limit stop, so as to provide resistance to stop the railcar, effectively improving the response efficiency and safety in emergency situations.
