Description

Technical Field

[0001] This utility model belongs to the field of railway vehicle inspection technology, and in particular relates to a bogie floating lever brake position size detection device. Background Technology

[0002] In the inspection of railway vehicles, the distance between the center of the bogie's traveling lever tie rod hole and the center of the bolster, the vertical distance from the center of the traveling lever tie rod hole to the rail surface, and the angle between the traveling lever and the vertical plane are crucial, affecting the safety and stability of vehicle operation. Traditional measurement methods rely heavily on manual operation, and the center of the traveling lever tie rod hole is a spatial point, resulting in low measurement efficiency and unstable accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a bogie floating lever brake position dimension detection device, which solves the problems of traditional measuring devices relying on manual operation, low measurement efficiency, and unstable accuracy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bogie traveling lever brake position dimension detection device includes a center pin seat, an elongated hole seat, a lever seat, a lever ruler seat, a ruler head, a transverse ruler, and a longitudinal ruler. The center pin seat is conical, with both its upper and lower surfaces being horizontal. The upper surface has an internally threaded hole and a center graduation line. The elongated hole seat is wedge-shaped, with both its upper and lower surfaces being horizontal. A cylinder is connected to its upper surface, and the cylinder has an internally threaded hole at its center. A circular bubble level is fixed to the upper surfaces of the center pin seat and the elongated hole seat, respectively. The ruler head has an observation hole on its upper front surface and a center graduation line at its center, and a stud at its lower part. A ruler head is threadedly connected to both the center pin seat and the upper surface of the cylinder. The transverse ruler passes through... A central pin seat and a ruler head on the cylinder are fixed to each other. The 0 mark of the horizontal ruler is aligned with the center mark of the ruler head on the central pin seat. A bar bubble level is fixed above the lever seat, with the length of the bar bubble level aligned with the length of the lever seat. Pin holes are provided on both sides of the lever seat. Horizontal pin holes are provided on both sides of the lever ruler seat. The two sides of the lever seat and the two sides of the lever ruler seat are connected by fixing pins. A center mark is provided at the center of the fixing pin. A fixing plate is connected to the center of the top of the lever ruler seat. An internal thread is provided at the center of the fixing plate. The ruler head is connected to the fixing plate by the thread. One end of the longitudinal ruler passes through the horizontal ruler and is fixed, and the other end passes through the ruler head above the fixing plate and is fixed. The longitudinal ruler is perpendicular to the horizontal ruler.

[0006] Preferably, the lever seat includes a top plate, side plates, and a fastening plate. The side plates are vertically fixed below both ends of the top plate, and the fastening plate is vertically fixed below the rear side of the top plate. The entire lever seat is groove-shaped, with a stud fixed in the center inside. A nut is slidably connected to the stud. A set screw is inserted into the fastening plate. A strip bubble level is fixed above the outer side of the top plate. The length direction of the strip bubble level is consistent with the length direction of the top plate. Pin holes are provided on both side plates.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-2As shown, a bogie traveling lever brake position dimension detection device includes a center pin seat 1, an elongated hole seat 2, a lever seat 3, a lever ruler seat 4, a first ruler head 5, a second ruler head 6, a third ruler head 7, a transverse ruler 8, and a longitudinal ruler 9. The center pin seat 1 is conical, with both its upper and lower surfaces being horizontal. The upper surface has an internally threaded hole and a center scale line. The elongated hole seat 2 is wedge-shaped, with both its upper and lower surfaces being horizontal. A cylinder 10 is connected to its upper surface, and the cylinder 10 has an internally threaded hole at its center. A circular bubble level 11 is fixed to the upper surfaces of the center pin seat 1 and the elongated hole seat 2, respectively. The first ruler head 5 and the second ruler head 9 are also present. 6. The upper front of the third ruler 7 has an observation hole and a center scale line, and the lower part is a stud; the upper surface of the center pin seat 1 is connected to the first ruler 5 by a thread; the upper surface of the cylinder 10 is connected to the second ruler 6 by a thread; the transverse ruler 8 passes through the first ruler 5 and the second ruler 6 and is fixed to them respectively, and the 0 scale line of the transverse ruler 8 is aligned with the center scale line of the first ruler 5; the lever seat 3 includes a top plate 31, a side plate 32 and a fastening plate 33, the side plates 32 are vertically fixed at both ends of the top plate 31, and the fastening plate 33 is vertically fixed at the lower rear side of the top plate 31. The entire lever seat 3 forms a groove shape, and the stud 13 is fixed in the center inside. The upper plate 33 is connected to the sliding connection of the fixing nut 16, and the fastening plate 33 is fitted with the set screw 17. The top plate 31 is fixed with the bar bubble level 12, the length direction of the bar bubble level 12 is consistent with the length direction of the top plate 31, and the two side plates 32 are provided with pin holes; the lever base 4 includes a plumb bob 41 and a bracket 42. The bracket 42 is fixed above the plumb bob 41. The bracket 42 has horizontal pin holes on both sides. The two side plates 32 of the lever base 3 are connected to the bracket 42 by fixing pins 14. The fixing pin 14 has a center scale line. The top center of the bracket 42 is connected to the fixing plate 15. The fixing plate 15 has an internal thread at its center. The fixing plate 15 is connected to the fixing plate 15 by the thread. Connect the third ruler 7.
