Description
Technical field
The utility model relates to crane safety technical field, particularly a kind of hoisting crane grounding-for-lightning device.
Background technology
Rail mounted harbor accommodation are all use under environment in the open substantially, and complete machine height is higher, belong to tall and slender structure, be easy to be struck by lightning at thunderstorm season, this likely can give rail mounted harbor accommodation bring structure, mechanism, electrically on damage, there is very large potential safety hazard, therefore, rail mounted harbor accommodation generally all can be installed grounding-for-lightning device and solve above-mentioned potential safety hazard.Current track formula harbor accommodation grounding-for-lightning device mainly utilizes slide block deadweight to keep the contact of slide block and track or wheel etc., and this mode must ensure that slide block has enough weight, but contact is unstable, therefore still there is serious potential safety hazard.
Utility model content
In view of this, the utility model provides a kind of hoisting crane grounding-for-lightning device, unstable to solve lightning-arrest effect, there is the problem of potential safety hazard.
The utility model provides a kind of hoisting crane grounding-for-lightning device, the grounding jumper comprising erection support, elastic body, slide block and be connected with described slide block, described erection support is fixed on bogie frame, and described erection support is provided with guiding mechanism, and described slide block and guiding mechanism form moving sets; Described elastic body is arranged between erection support and slide block, for described slide block is pressed on wheel, track or ground along the moving direction of slide block on guiding mechanism.
Further, described elastic body is spring.
Further, described guiding mechanism is that first end is open, the guide groove of the second end shutoff, and described slide block is located in guide groove, and described spring is arranged between slide block and the second end.
Further, described erection support also comprises cover plate, and described guiding mechanism is cylindrical body, and described cover plate is fixed on the upper end of cylindrical body, and described slide block is arranged in cylindrical body, and described spring is arranged between slide block and cover plate.
Further, described cover plate has hole, the upper end of described slide block is thinner than lower end, forms step between top and bottom, and the upper end of described slide block is stretched out outside described hole, and described spring is between cover plate and step, and described grounding jumper is connected with the upper end of described slide block.
A kind of grounding-for-lightning device that the utility model provides, compared with prior art, because erection support is provided with guiding mechanism, slide block can move at guiding mechanism interior orientation, add the elastic body be arranged between erection support and slide block, make slide block be close to wheel, track or ground all the time, keep the reliability of ground connection, therefore lightning-arrest stability is high, eliminates potential safety hazard.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Mounting structure figure when Fig. 1 is the slide block ground connection of the utility model hoisting crane grounding-for-lightning device;
Fig. 2 is the slide block of the utility model hoisting crane grounding-for-lightning device mounting structure figure when connecing wheel;
Fig. 3 is the structural representation of the utility model hoisting crane grounding-for-lightning device.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figures 2 and 3, the utility model specific embodiment one provides a kind of hoisting crane grounding-for-lightning device, this hoisting crane grounding-for-lightning device comprises erection support 1, slide block 6, spring 4 and grounding jumper 2, erection support 1 comprises the cylindrical body 5 with directional tagging and the cover plate 3 being arranged on cylindrical body 5 upper end, erection support 1 is fixed on bogie frame, slide block 6 is movably arranged in cylindrical body 5, and slide block 6 and cylindrical body 5 form moving sets; Spring 4 is arranged between cover plate 3 and slide block 6, there is certain amount of compression in spring 4, its one end is against cover plate 3, the other end is against slide block 6, all the time give slide block 6 thrust, make slide block 6 be close to wheel 7, keep good contact, cover plate 3 has hole, and grounding jumper 2 passes hole and is connected to the upper end of slide block 6.
The conveniently connection of grounding jumper 2, also in order to lead to spring 4, preferably can be designed to upper end thin for slide block 6, lower end is thick, and the position that top and bottom connect forms step, and spring 4 is enclosed within the upper end of slide block 6, and hole is stretched out in the upper end of slide block 6, grounding jumper 2 is connected with the upper end of slide block 6; Like this, spring 4 is pressed between cover plate 3 and step, the spacing and directional tagging that the upper end of slide block 6 can also give spring 4 certain, prevents spring 4 deflection and loses efficacy.
It should be noted that, guiding mechanism on erection support 1 can also be guide groove, this guide groove upper end shutoff, lower end is open, and slide block 6 is movably arranged in guide groove, moving sets is formed with guide groove, spring 4 one end against the end of guide groove shutoff, the other end against the upper end of slide block 6, certainly, guide groove upper end also has the hole passed for grounding jumper 2, and grounding jumper 2 can be connected with the upper end of slide block 6 smoothly; In addition, above-mentioned spring 4 can also substitute, as long as can give slide block 6 predetermincd tension all the time with other elastic body.
Above-mentioned grounding-for-lightning device, because erection support 1 is provided with guiding mechanism, slide block 6 can move at guiding mechanism interior orientation, add the spring 4 be arranged between erection support 1 and slide block 6, slide block 6 is made to be close to wheel 7 all the time, keep the reliability of ground connection, therefore lightning-arrest stability is high, eliminates potential safety hazard.
As shown in figs. 1 and 3, the utility model specific embodiment two provides a kind of grounding-for-lightning device, is with specific embodiment one difference, the lower end of slide block 6 contacts with ground 8, in wheel 7 rolling process, slide block 6 lower end keeps good contact with ground 8 all the time, ensures lightning protective earthing stability.It should be noted that, slide block 6 lower end can also contact with track, as long as can ensure ground connection stablizing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
