Embodiment 1

[0072] as attached figure 1 to attach Figure 12 As shown, an embodiment of the self-tightening sleeper fastener bolt operation vehicle of the present invention, the operation vehicle 100 specifically includes:

[0073]The vehicle frame 2 supported on the rail 11 by the wheel set 15;

[0074] A subframe 9 arranged laterally on the vehicle frame 2; the subframe 9 can be further specifically installed below the vehicle frame 2;

[0075] The operating mechanism 3 is arranged on at least one of the left and right sides of the sub-frame 9 and is located outside the vehicle frame 2 along the transverse direction.

[0076] The operating mechanism 3 is provided with a sensor assembly 306 for detecting the bolt 13 , an image acquisition assembly 305 for positioning the bolt 13 , and an elastic shaft device 304 for tightening or loosening the bolt 13 . The working mechanism 3 can drive the elastic shaft device 304 to move laterally, longitudinally and vertically relative to the sub-f...

Embodiment 2

[0089] A kind of embodiment as described in embodiment 1 self-tightening sleeper fastener bolt operation method embodiment, this method specifically comprises the following steps:

[0090] S10) When the work vehicle 100 is running, the sensor assembly 306 detects the bolt 13 at the same time;

[0091] S20) When the sensor assembly 306 detects the bolt 13, the work vehicle 100 brakes and stops walking, and simultaneously clamps the rail 11 through the rail clamping device 10;

[0092] S30) The image acquisition component 305 starts taking pictures and acquires the position of the bolt 13, and the longitudinal drive mechanism 308 drives the elastic shaft device 304 to move a corresponding distance;

[0093] S40) When the elastic shaft device 304 reaches the designated position, the vertical driving mechanism 310 presses down for a set distance so that the sleeve 30407 is placed on the bolt 13;

[0094] S50) The drive unit 30401 of the elastic shaft device 304 starts to rotate, an...

Abstract

The invention discloses a self-tightening-and-loosening sleeper fastener bolt operation vehicle and an operation method thereof. The operation vehicle comprises a vehicle frame supported on a steel rail by a wheel set, an auxiliary frame transversely arranged on the frame, and an operation mechanism which is arranged on at least one of the left side and the right side of the auxiliary frame and located on the transverse outer side of the frame. The operation mechanism is provided with a sensor assembly used for bolt detection, an image acquisition assembly used for bolt positioning, and a tightening and loosening shaft device used for tightening or loosening a bolt. The operation mechanism can drive the loosening and tightening shaft device to move in the transverse direction, the longitudinal direction and the vertical direction relative to the auxiliary frame so as to position and align the bolts. The operation vehicle can solve technical problems that in an existing sleeper bolt dismounting mode, positioning precision between the operation mechanism and the bolts is not high, a transverse distance between bolt wrenches is fixed, and a large change of a bolt distance cannot be adapted.

Description

technical field [0001] The invention relates to the technical field of track engineering machinery, in particular to an operating trolley and an operating method for self-releasing bolts of sleeper fasteners used in the disassembly and assembly of railway sleeper fasteners. Background technique [0002] In the field of railway engineering, railway rails need to be replaced in time when they reach a certain life span. At present, railway rail replacement operations mainly use manual or mechanical rail replacement in the skylight point. Rail fasteners are parts used to connect rails and sleepers (or other types of under-rail foundations) on railway tracks, also known as intermediate connecting parts. Its function is to fix the rail on the sleeper, maintain the gauge and prevent the vertical and horizontal movement of the rail relative to the sleeper. It is a key component to ensure the safety of railway operation. At present, the most commonly used one for fixing the rail tra...
