Technical Field

The invention relates to the technical field of rail engineering machinery, in particular to an operating device and an operating method of a self-tightening sleeper fastener bolt applied to dismounting and mounting of a railway sleeper fastener.

Background

In the field of railway engineering, railway rails need to be replaced in time when reaching a certain service life, and the conventional railway rail replacement operation mainly adopts a manual rail replacement mode or a mechanical rail replacement mode in a skylight point. Rail fasteners are parts of a railway track used to connect rails to sleepers (or other types of undersized foundations), also known as intermediate connecting parts. The rail fixing device has the functions of fixing the steel rail on the sleeper, keeping the track gauge and preventing the steel rail from moving longitudinally and transversely relative to the sleeper, and is a key component for ensuring the operation safety of the railway. Currently, the most common type of fixed rail track is the spring bar I-type rail fastener, which includes an omega spring bar, a screw spike and a circular washer, the screw spike including a nut and a bolt. The rail and sleeper replacement construction requires the separation of the rail and the sleeper, so that the disassembly operation of the rail fastener is required, and the disassembly of the rail fastener is one of the important steps of the rail and sleeper replacement construction.

At present, the dismantlement of rail fastener is still mainly accomplished by the manual work, specifically adopts manpower internal combustion spanner segmentation parallel operation, and the operation workman uses professional rail fastener electric spanner, dismantles rail fastener one by one at the railway scene. The method has the advantages that the operation is flexible, the operators can be arranged according to different maintenance amounts, the applicability is strong, and although the manual disassembly operation has high reliability and strong subjectivity, the method has the defects of low efficiency and high danger of the disassembly operation, time and labor consumption in the disassembly process and the like. Particularly when long-distance maintenance is faced, a large number of personnel and machines need to be dispatched, and the following defects exist:

(1) the labor demand is high;

(2) the scheduling coordination is complex;

(3) the number of field personnel is large, and the safety risk is large.

As a typical job scenario: on the rail replacing construction site, 2 operators are equipped for dismounting the fasteners specially every 100 meters, 40 operators for dismounting the fasteners and 40 internal combustion engine-driven wrenches are equipped for replacing the rails in the skylight point for 2 kilometers, and in order to complete construction smoothly in the skylight point without delaying other rail replacing working procedure operation time, the time for dismounting the fasteners is very short, and the labor intensity is very high. After the operation is finished, the transferring work of the 40 internal combustion wrenches is also complicated, and due to the fact that the number of operation tools is too large, the wrenches cannot be transported by vehicles, and the wrenches can only be pushed to the next skylight point (2 kilometers need to be transferred when the wrenches are operated for 2 kilometers), so that more manpower and time are occupied, and unified nursing and management of machines and tools are not facilitated.

In prior art, the vehicle that adopts automatic operation mode to carry out the dismouting of sleeper fastener nut has also appeared at present, if: the nut dismounting and mounting vehicle for the sleeper fastener is applied by Han Peng electronic technology Limited in Changsha on day 13 in 2019 and is applied by China invention with publication number CN110303332A on day 8 in 10 in 2019.

This sleeper fastener nut dismouting car carries out the automation mechanized operation to sleeper fastener nut through dismouting mechanism, has improved the operating efficiency of dismouting nut, has reduced the operating cost of dismouting nut. However, the disassembly and assembly vehicle is a large maintenance machine, a power system adopts a diesel generator set or a contact net electricity-taking unit, the disassembly and assembly mechanism is located below a vehicle body, and a detection system adopts two-stage detection. Meanwhile, the dismounting mechanism can only move and be adjusted in two directions, adjustment along the direction of the sleeper is lacked, the dismounting mechanism adopts a pneumatic impact wrench, and tightness moment cannot be accurately controlled. Secondly, the positioning accuracy between this dismouting car operation device and the bolt is not high, and the lateral distance between the bolt spanner is fixed, can't adapt to the great condition of bolt interval change, also can't adapt to the condition that the bolt height differs.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or be indirectly disposed on the other element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "plurality" or "a plurality" means two or more unless specifically limited otherwise.

It should be understood that the structures, ratios, sizes, and the like shown in the drawings are only used for matching the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the practical limit conditions of the present application, so that the modifications of the structures, the changes of the ratio relationships, or the adjustment of the sizes, do not have the technical essence, and the modifications, the changes of the ratio relationships, or the adjustment of the sizes, are all within the scope of the technical contents disclosed in the present application without affecting the efficacy and the achievable purpose of the present application.

Referring to fig. 1 to 21, embodiments of the self-tightening tie fastener bolt operation device and the operation method according to the present invention are shown, and the present invention will be further described with reference to the drawings and the embodiments.
