Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary tooling technology for train maintenance, specifically a bidirectional track train blocking device. Background Technology
[0002] Traffic blocking devices are crucial safety equipment in traffic maintenance operations, their core function being to isolate adjacent vehicles and prevent collisions during maintenance. Currently, most devices used in the industry are unidirectional, their structure limiting them to blocking in only one direction. Therefore, in complex maintenance conditions, multiple devices often need to be deployed for coordinated operation, increasing both equipment investment and on-site coordination complexity. Furthermore, another major limitation of existing devices is the lack of an effective status feedback mechanism. Operators cannot remotely confirm whether the blocking device is correctly installed and in place, requiring them to physically visit the installation point for close inspection. This process leads to frequent travel between the work site and the installation point, significantly reducing maintenance efficiency and increasing on-site safety risks. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bidirectional railcar blocking device, which has the function of being usable in both directions and being able to judge the installation status of the blocking device from a distance.
[0004] The technical solution adopted by this utility model to solve its technical problem is: A bidirectional railcar blocking device includes a base, blocking plates, and a warning flag. The base is connected to the railcar, and blocking plates are respectively installed at both ends of the base. A warning flag is installed between the two blocking plates.
[0005] Compared with the prior art, the beneficial effects of the present invention are: This utility model features a compact structure with a bidirectional blocking plate and a warning flag added to the base. It can form a bidirectional barrier, which enhances safety. The addition of the warning flag allows operators to observe the installation of the blocking device from a distance, avoiding the need to travel back and forth between the work point and the installation point.
[0006] As a preferred embodiment, a further technical solution of this utility model is: Preferably, the two barriers are connected by a handling handle, and a flagpole is set at each end of the handling handle, with a warning flag set on each flagpole.
[0007] Preferably, limit switches are provided at both ends of the base, and an audible and visual alarm is provided in the middle of the base. The two limit switches are respectively linked to the audible and visual alarm.
[0008] Preferably, the base has a U-shaped structure, is fastened to the trolley rail, and has a threaded hole on the side of the base, with a positioning screw connected to the threaded hole.
[0009] Preferably, the flagpole includes a telescopic pole and a fixed pole. The lower end of the telescopic pole is provided with a positioning hole, and a positioning pin is movably disposed in the positioning hole. The positioning pin is connected to an elastic element placed inside the telescopic pole. The lower end of the fixed pole is fixedly connected to a handling handle. Several fixing holes that are adapted to the positioning pin are provided at intervals along the length direction on the side wall of the fixed pole. The lower end of the telescopic pole is inserted into the upper end of the fixed pole and connected to the fixed pole through the cooperation of the positioning pin and the fixing holes.

[0011] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.
[0012] like Figures 1 to 3 As shown, a bidirectional track vehicle blocking device consists of a base, blocking plates, and warning flags. The base has a U-shaped structure and is fastened onto the track. Triangular blocking plates are fixedly welded to the left and right ends of the base, and the blocking plates are placed in the middle of the base to block the vehicle.
[0013] In this embodiment, the two baffles are connected by a handling handle. The surface of the handling handle is provided with a rubber pad to improve the comfort of the operator's hands when handling the equipment. The surface of the rubber pad in this embodiment may be textured to increase friction with the palm of the hand.
[0014] Each end of the carrying handle has a flagpole, and a warning flag is affixed to the top of each flagpole. In this embodiment, the flagpole consists of a telescopic rod and a fixed rod. The lower end of the telescopic rod has a positioning hole, within which a positioning pin is movably installed. An elastic element, which can be a V-shaped spring, is installed inside the telescopic rod. The positioning pin is fixedly connected to one end of the elastic element. The lower end of the fixed rod connects to the carrying handle. Several fixing holes, matching the positioning pins, are spaced along the length of the fixed rod. The lower end of the telescopic rod inserts into the upper end of the fixed rod and is connected to the fixed rod through the engagement of the positioning pins with the fixing holes. By pressing the positioning pins, the length of the telescopic rod extending beyond the fixed rod can be adjusted, facilitating the adjustment of the warning flag height.
[0015] In this embodiment, mounting brackets are fixedly connected to both ends of the base, and limit switches are installed on each mounting bracket. An audible and visual alarm is set in the middle of the base. The two limit switches are linked to the audible and visual alarm. When the wheel touches the limit switch, the limit switch is triggered, and the audible and visual alarm sounds an alarm.
[0016] In this embodiment, at least two threaded holes are provided on one side wall of the base, and a positioning screw is threaded into the threaded hole. The base is fastened to the trolley rail by the positioning screw, and the base can be adapted to trolley rails of different sizes by adjusting the positioning screw.
[0017] In this embodiment, the base is fastened onto the trolley rail, and then the positioning screw on the side of the base is tightened to ensure it is firmly against the side of the trolley rail, thus securing the base to the rail. Then, the positioning pin is pressed to adjust the length of the telescopic rod's extension and fixing rod to adjust the height of the warning flag.
[0018] This utility model features a compact structure with a bidirectional blocking plate and a warning flag added to the base. It can form a bidirectional barrier, which enhances safety. The addition of the warning flag allows operators to observe the installation of the blocking device from a distance, avoiding the need to travel back and forth between the work point and the installation point.
[0019] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
