Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of urban rail transit, in particular to an online inspection technology for quickly inspecting and repairing a certain section of a track within a short period of time, and specifically to an online inspection vehicle for rail transit. Background Art

[0002] With the development of my country's cities, more and more underground rail transit systems are being built and put into use. At the same time, with the increasing frequency of use and the continuous shortening of departure intervals, the time available for maintenance, upkeep and inspection of the tunnels where the underground rails are located is becoming increasingly shorter.

[0003] During the actual operation of underground rail transit, sudden situations in tunnels cannot sometimes be resolved by remote monitoring or remote control. If it is necessary to enter the tunnel for troubleshooting or maintenance, there is currently no good "online" maintenance method. However, if the system needs to be shut down for maintenance, it will have an adverse impact on the operation of the entire rail transit network. Summary of the Invention

[0004] The purpose of the utility model is to overcome the above-mentioned defects and to provide an on-line inspection vehicle which is easy to use and can quickly inspect, repair and maintain the track when it is on-line.

[0005] In order to achieve the above object, the utility model is achieved as follows:

[0006] An online inspection vehicle for rail transit, characterized by comprising a vehicle body frame, a chassis, a seat, a transmission mechanism, and a pedal;

[0007] The bottom of the vehicle body frame is provided with a chassis, and the seat is provided on the upper surface of the vehicle body frame through a transmission mechanism. The transmission mechanism includes gears, chains and pedal cranks. The outer side of the pedal cranks is connected to pedals. By stepping on the pedals, the chain drives the gears to rotate and control the inspection vehicle to move forward or stop.

[0008] The vehicle body base frame is telescopic, and the seat is foldable. It is rotatably connected to the vehicle body base frame via a rotating shaft. The seat can be laid flat and placed on the vehicle body base frame by folding.

[0009] The on-line inspection vehicle for rail transit is characterized in that the vehicle body frame can be folded as a whole, and the steel pipe in the middle of the seat body frame is hinged to achieve the folding of the vehicle body frame as a whole.

[0010] The online inspection vehicle for rail transit is characterized in that the chassis includes a wheel axle and a wheel hub, and the wheel hub is installed on both sides of the vehicle body frame through the wheel axle.

[0011] The on-line inspection vehicle for rail transit is characterized in that the outer ring of the wheel hub is wrapped with insulating material.

[0012] The on-line inspection vehicle for rail transit is characterized in that the insulating material is acrylic fiber.

[0013] The rail transit online inspection vehicle is characterized in that it also includes a storage plate installed on the upper part of the vehicle body frame.

[0014] The on-line inspection vehicle for rail transit is characterized in that the vehicle body frame is welded with stainless steel pipes.

[0015] The beneficial effects of the present invention are as follows: the online inspection vehicle of the present application has its wheel hub wrapped with insulating material on the outside, so it can be operated with power on without power outage; secondly, the present application transmits power through a chain connection, and does not require an additional power supply connection; and its seat is foldable, it can be folded and laid flat on the vehicle body frame, it is small in size, and is made of stainless steel as a whole, so it is light and easy to pick up, and is suitable for daily inspection and maintenance.

[0020] The present invention is further described below through specific embodiments.

[0021] like Figure 1-2 As shown: An online inspection vehicle for rail transit, comprising a vehicle body frame 1, a chassis 2, a seat 3, a transmission mechanism 4, and a pedal 5;

[0022] The bottom of the vehicle body frame is provided with a chassis, and the seat is provided on the upper surface of the vehicle body frame through a transmission mechanism. The transmission mechanism includes gears, chains and pedal cranks. The outer side of the pedal cranks is connected to pedals. By stepping on the pedals, the chain drives the gears to rotate and control the inspection vehicle to move forward or stop.

[0023] like Figure 3 As shown: the vehicle body frame is telescopic, and the seat is foldable, which is rotatably connected to the vehicle body frame through a rotating shaft. The seat can be laid flat and placed on the vehicle body frame by folding.

[0024] The chassis includes a wheel axle and a wheel hub, and the wheel hub is mounted on both sides of the vehicle body base frame through the wheel axle.

[0025] The outer ring of the hub is wrapped with insulating material; the insulating material is acrylic fiber; the insulating material is used to achieve online inspection and maintenance.

[0026] Furthermore, it also includes a storage plate 6, which is installed on the upper part of the vehicle body base frame; during daily maintenance or inspection, tools can be placed on the storage plate.

[0027] Furthermore, the vehicle body frame is welded from stainless steel pipes, making it lightweight as a whole.

[0028] like Figure 4 As shown, the entire vehicle frame is foldable, and the steel tubes in the middle of the seat frame are hinged, allowing the entire frame to be folded in half. Specifically, the steel tubes in front of the seat are hinged, allowing the front of the chassis and rollers to be folded backwards, making the entire application smaller and easier to carry.
