The invention relates to a part of a hydraulic cementing clamping plate dismounting device, in particular to a combined cutter device of the hydraulic cementing insulating clamping plate dismounting device.

Background

When the glued insulation splint at the insulation joint part on the early railway line is suddenly broken or damaged, a method of inserting the short rail after sawing is generally adopted, but the method consumes labor and time and has high raw material cost. The joint is one of three key parts of railway line defects and occupies an important position in the work maintenance, and particularly, the insulating joint part not only directly influences indexes such as line smoothness, but also has a great influence on signal control and the like which influence the safe operation of the line. Therefore, in recent years, a cementing clamp plate vulcanization dismounting machine is developed, the strength of an adhesive is reduced by adopting a heating method, the dismounting is convenient, the use is limited due to various defects caused by heating, a novel cold dismounting device is urgently needed to meet the requirement of site construction, and meanwhile, steel rails and concrete sleepers are protected from being damaged by heat.

In recent years, a cementing splint vulcanization dismounting machine is developed, and the principle of the cementing splint vulcanization dismounting machine is that combustible gas or electricity is used as energy, the temperature is controlled to be about 300 ℃, and a binder is melted so as to conveniently dismount a cementing insulation splint. The method has high operation requirement, is difficult to disassemble due to uneven fire baking and insufficient fire, is easy to burn workers, and has certain danger. The operation environment is basically in open field, the clamping plate is required to have certain thickness, the viscose on the back side of the clamping plate needs to be baked and melted by fire, the clamping plate needs to be baked by fire, the heating is needed for 30 to 40 minutes in winter, and the requirement for repairing skylight points is difficult to meet. Particularly, in case of poor temperature control, irreversible heat damage to the steel rail is easily caused, and the concrete sleeper is easily scrapped in advance due to heating. Meanwhile, toxic and harmful gas generated during heating has adverse effects on the health of operators.

The novel cold dismantling device for the steel rail glued joint insulating joint is an ideal choice, and the main dismantling principle is as follows: the hydraulic power device outputs enough mechanical force to enable the clamping plate and the rail web to generate enough displacement, so that the purposes of separation and removal are achieved. According to the standard, an adhesive with high strength and high toughness is filled between a clamping plate and a rail web, a qualified 60kg/m rail type adhesive insulation joint is taken as an example, the resistance of a longitudinal joint is up to 3000kN, the clamping plate needs to be detached from the rail web, large mechanical force is needed, a tool bit of a long cutter is a direct execution mechanism for detaching the adhesive clamping plate, the tool bit is large in stress, easy to damage, short in service life and frequent to replace, a tool handle of the long cutter is a part stressed by pressure, the stress condition is good, the tool handle and the tool bit are integrated and cannot be damaged easily, the cost is high, and the loss is large.

Detailed Description

In order to better understand the technical solutions of the present invention, the following further describes the technical solutions of the present invention with reference to the accompanying drawings and examples.

Referring to fig. 1, the combined cutter device for a hydraulic insulation plywood dismounting device provided by the invention is arranged on a main frame 100 of the hydraulic insulation plywood dismounting device, and comprises two symmetrically arranged fixed cutters 200, so that the work of dismounting the insulation plywood can be better completed.

Each fixed cutter 200 comprises a cutter handle 1, a cutter head 2 and a magnet 3.

The rear end of the knife handle 1 is connected with the main frame 100 through a screw, and the front end is connected with the knife head 2.

The working surface 4 of the cutting head 3 (the side facing the web of the rail) is configured as a circular arc, the radius of which corresponds to the radius of the web.

The magnet 3 is embedded in the side surface of the shank 1 facing the rail web of the rail (the side surface in contact with the rail web).

The magnet 3 is cylindrical, has the diameter of 20mm and the height of 20mm, is embedded and fixed on the side surface of the cutter handle 1 by adopting an adhesive and can be adsorbed on the rail web part of the steel rail, thereby well assisting the positioning of the combined type cutter device on the steel rail and being positioned on the position matched with the rail web of the steel rail.

The contact surface between handle of a knife 1 and tool bit 2 adopts the mode that recess and boss inlayed each other to be connected, offers recess 5 promptly on the contact surface of handle of a knife 1, is equipped with the boss 6 with recess 5 looks adaptation on the contact surface of tool bit 2 to rethread screw 7 is fixed in on the handle of a knife 1. This arrangement allows the forces of the cutting head 2 during the removal of the hydraulically glued clamp to be better transmitted to the shank 1 without the screws 7 between them being damaged.

As mentioned above, the technical requirement of on-site adhesive joint insulation joint is found in TB/T2975-2018 steel rail adhesive joint insulation joint, according to the standard, an adhesive with high strength and high toughness is filled between the clamping plate and the rail web, taking an qualified 60kg/m steel rail type adhesive joint insulation joint as an example, the longitudinal joint resistance is up to 3000kN, so that the clamping plate needs to be detached from the rail web, a larger mechanical force is needed, the cutter head of the long cutter is a direct execution mechanism for detaching the adhesive clamping plate, is large in stress, easy to damage, short in service life and needs to be replaced frequently, and the cutter handle of the long cutter is a part stressed by pressure, good in stress condition and difficult to damage, and is high in cost and large in loss if the cutter head is replaced together as a whole. The combined type cutter device is formed by combining the cutter handle 1 and the cutter head 2, and the cost of cutter manufacturing materials and heat treatment is greatly saved only by replacing the cutter head 2. The cutter head 2 is a direct actuating mechanism for disassembling the glued splint, has large stress and can ensure the performance of the glued splint by adopting advanced materials and advanced heat treatment processes. The knife handle 1 is a part stressed by pressure, is good in stress condition and not easy to damage, actually only plays a role in connecting the knife head 2 and the main frame 100, and can be made of light materials, such as aluminum alloy, in order to achieve the effect of light weight of products.
