Abstract
The utility model discloses a novel crane twistlock device, its aim at provide in the ability reduction work crane twistlock device to the scratch of rail, twistlock device tapered end surface is equipped with the copper plate.
Description
Technical field
This utility model relates to bridge crane load-engaging device, particularly relates to a kind of novel crane rotary-locking device.
Background technology
The crane of important use when the crane of digital 100 meters of rail clamps and ground remote control system is to overhaul for 100 meters of rail entruckings of handling and ground installation, owing to 100 meters of rail and 25 meters of rail compare, span, weight adds 4 times the most simultaneously, require that two cranes realize synchronous operation, and the smoothness to overall operation, speed, there are strict requirements, original design is that lockset hangs, during allocation and transportation, owing to rail itself has certain toughness, the rail amplitude of oscillation is bigger, cause rail head of rail surface and the friction of lockset tapered end bigger, easily cause the quality accident of rail head of rail galled spots, have a strong impact on the product quality of rail.
Summary of the invention
The technical problems to be solved in the utility model is to provide the novel crane rotary-locking device of a kind of scratch that can reduce in work rail.
For reaching above-mentioned purpose, this utility model one novel crane rotary-locking device, described rotary-locking device tapered end surface is provided with copper plate.
Wherein said thickness of coated copper layer is 5mm.
Wherein said copper plate material is pyrite.
This utility model crane rotary-locking device difference from prior art is that this utility model achieves following technique effect:
This utility model is by processing (copper plate) by the rotary-locking device tapered end copper coating of original hundred meters of cranes, make the hardness of tapered end Facing material less than rail hardness, reduce or stop the scratch to rail of the rotary-locking device tapered end surface of hundred meters of cranes in work, improving the quality of hundred meters of rail.
The utility model is described in further detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 and 2 is the structural representation of existing crane rotary-locking device；
Fig. 3 and Fig. 4 be respectively Fig. 1 and and 3 improve after the structural representation of this utility model crane rotary-locking device.
Description of reference numerals: 1-copper plate.
Detailed description of the invention
Below in conjunction with drawings and Examples, to this utility model, above-mentioned and other technical characteristic and advantage are described in more detail.
As illustrated in fig. 1 and 2, it is crane rotary-locking device structural representation for original design, during handling, owing to rail itself has certain toughness, the rail amplitude of oscillation is relatively big, causes rail head of rail surface and the friction of lockset tapered end bigger, easily cause the quality accident of rail head of rail galled spots, having a strong impact on the product quality of rail, production efficiency, the material of former rotary-locking device tapered end is No. 45 steel, and hardness is higher.
As shown in Figures 3 and 4, this utility model is that the rotary-locking device tapered end copper coating of original hundred meters of cranes is processed (copper plate 1), make the hardness of tapered end Facing material less than rail hardness, reduce or stop the scratch to rail of the rotary-locking device tapered end surface of hundred meters of cranes in work.Improve the quality of hundred meters of rail.
Original tapered end, in the case of that do not affect original force structure and overall dimensions, is carried out Surface Machining by this utility model, and the position of tapered end contact rail is removed 5 millimeters, then removal position pyrite carried out polishing, then carry out external form processing.
Embodiment described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
