Description

TECHNICAL FIELD

[0001] The embodiment of the present disclosure relates to the technical field of track drilling devices, in particular to an F rail track drilling vehicle. BACKGROUND

[0002] The F rail track has the functions of supporting the maglev vehicle, bearing the suspension force, guiding force and traction force of the vehicle, and is the basis for the suspension and running of the maglev train. The F rail track is composed of F rail, sleeper and fastener, and a continuous aluminum induction plate is laid on the F rail. The aluminum induction plate usually needs to be fixed on the F rail by screws, so a large number of group drilling operations are required during the processing of the F rail track.

[0003] At present, there are the following ways to drill holes on the F rail: (1) using a portable and movable magnetic drill; (2) using a fixed drilling device such as a drilling machine; (3) using a large numerical control machine tool for drilling.

[0004] Due to the large number of hole groups on the track, if a portable and movable magnetic drill is used for drilling, workers need to first mark the drilling position and then manually drill by constantly adjusting the position of the magnetic drill, which is labor-intensive. If a fixed drilling machine is used for drilling, the F rail needs to be constantly moved to adjust the drilling position, which is extremely inconvenient due to the large weight and volume of the F rail track. If a large numerical control machine tool is used for tapping operation, the processing cost is high.

[0005] Therefore, it is necessary to improve one or more problems in the above-mentioned related technical solutions.

[0006] It should be noted that this section aims to provide background or context to the technical solutions of the present disclosure stated in the claims. The description herein is not admitted to be prior art merely because it is included in this section. CONTENT OF THE UTILITY MODEL

[0056] Specifically, a linear guide rail 13 is arranged on the front end face of the car body assembly 1, and the linear guide rail 13 is used to mount the main shaft assembly 6. The number of the linear guide rails 13 can be two, and the linear guide rails 13 are arranged in parallel.

[0057] The wheel assembly 2 is arranged on the lower end face of the car body assembly 1, and is used to walk on the F-rail 10. The brake assembly 3 is arranged on the car body assembly 1, and is used to brake the drilling car, so that the drilling car is in the punching position of the F-rail 10.

The handle 12 is mounted at the middle position of the end plate 111 and the side plate 112, respectively, and the linear guide rail 13 is arranged vertically and symmetrically along the width of the end plate 111.

[0068] II. Wheel assembly 2

[0069] As shown in Figure 3 , Figure 4 and Figure 5 , the wheel assembly 2 comprises two guide wheel sets 21 and an auxiliary load-bearing wheel set 22. The two guide wheel sets 21 are mounted in the wheel set mounting grooves of the side plates 112 of the box frame 11, and the auxiliary load-bearing wheel set 22 is mounted in the wheel set mounting groove of the support plate 114 of the box frame 11.

[0070] The guide wheel set 21 comprises a guide wheel 211, a wheel shaft 212, a bearing 213, an end stop ring 214 and a bearing spacer 215. The guide wheel 211 has a protruding rim at both ends for guiding and limiting. The wheel shaft 212 has a rectangular face formed on the cylindrical surface at both ends. When mounted, the flat surface of the wheel shaft 212 is combined with the flat surface of the wheel set mounting groove of the side plate 112 of the box frame 11, and the wheel shaft 212 has an end shoulder for limiting rotation and axial movement of the wheel shaft 212 during operation.
