Description
Technical field
The present invention relates to a kind of anti-drop structure of transmission line of electricity crane short warning device, a kind of structure occurring loosening or come off after preventing crane short warning device from installing on gib arm, belongs to power equipment supply technical field specifically.
Background technology
Along with the development of society and the quickening of urbanization process, power grid construction scale supporting has with it had the development of advancing by leaps and bounds, and various types of crane serves very large effect in construction, particularly truck mounted crane and tower crane.The thing followed is that the accident that crane causes gets more and more.Wherein, crane collision high-pressure transmission line of electricity is very serious accident, and this accident, once occur, will cause casualties and great economic loss.
At present, the transmission line of electricity crane short warning device kind that market uses is little, is substantially all install transmission line of electricity voltage detection unit on gib arm, by wired or to be wirelessly connected with the alarm unit of operator's compartment.Because gib arm is in operation process, shake larger, also can often touch various object, so transmission line of electricity voltage detection unit is in crane operation process, easy appearance loosens and obscission, if do not have Timeliness coverage, transmission line of electricity crane short warning device may lose the effect of warning, and the accident of crane collision high-pressure transmission line of electricity is more prone to occur.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of anti-drop structure of transmission line of electricity crane short warning device is provided, effectively can detect transmission line of electricity crane short warning device whether to occur loosening or coming off, effectively avoid the generation of safety misadventure.
According to technical scheme provided by the invention, a kind of anti-drop structure of transmission line of electricity crane short warning device comprises drain pan, it is characterized in that: drain pan is fixed two guide pin bushings, a lower guide pillar is provided with in each guide pin bushing, lower guide pillar can slide up and down along guide pin bushing, and drain pan can be stretched out in the bottom of lower guide pillar, lower guide pillar is provided with lower positioning table; Each lower guide pillar upper end is provided with a upper guide post, and upper guide post is provided with positioning table, is provided with spring between upper guide post and lower guide pillar, and spring upper end compresses the upper positioning table of contact, and lower end compresses the lower positioning table of contact; Be provided with short warning circuit plate above two upper guide posts, short warning circuit plate is provided with two touch controlled keys, and each touch controlled key compresses with a upper guide post upper end and contacts; Drain pan upper end connects case, in short warning circuit plate is coated on by case, and warning circuit plate and case is fixed by the thrust of spring.
Further, two guide pin bushings are symmetrical arranged.
Further, each guide pin bushing inside lower end is provided with limit dais, and limit dais can stop that lower positioning table is deviate from from guide pin bushing lower end.
Further, case is semisphere.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, easy and simple to handle, reliable operation; Effectively can detect transmission line of electricity crane short warning device whether to occur loosening or coming off, effectively avoid the generation of safety misadventure; Cost is lower, can apply on a large scale.

Description of reference numerals: positioning table, 6-spring, 7-upper guide post, the upper positioning table of 8-, 9-touch controlled key, 10-short warning circuit plate, 11-limit dais under guide pillar, 5-under 1-drain pan, 2-case, 3-guide pin bushing, 4-.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention mainly comprises drain pan 1, drain pan 1 is fixed two guide pin bushings, 3, two guide pin bushings 3 and is symmetrical arranged.Be provided with a lower guide pillar 4 in each guide pin bushing 3, lower guide pillar 4 can slide up and down along guide pin bushing 3, and drain pan 1 can be stretched out in the bottom of lower guide pillar 4.Described lower guide pillar 4 is provided with lower positioning table 5.
Each guide pin bushing 3 inside lower end is provided with limit dais 11, and limit dais 11 can stop that lower positioning table 5 is deviate from from guide pin bushing 3 lower end.
Each lower guide pillar 4 upper end is provided with a upper guide post 7, and upper guide post 7 is provided with positioning table 8.Be provided with spring 6 between upper guide post 7 and lower guide pillar 4, spring 6 upper end compresses the upper positioning table 8 of contact, and lower end compresses the lower positioning table 5 of contact.
Be provided with short warning circuit plate 10 above two upper guide posts 7, short warning circuit plate 10 is provided with two touch controlled keys 9, and each touch controlled key 9 compresses with upper guide post 7 upper end and contacts.
Drain pan 1 upper end connects hemispheric case 2, in short warning circuit plate 10 is coated on by case 2, and warning circuit plate 10 and case 2 is fixed by the thrust of spring 6.
Principle of work of the present invention is: when crane short warning device is installed on gib arm, spring upwards compresses by lower guide pillar, and the touch controlled key on short warning circuit plate is depressed by spring pressure by upper guide post.Now, short warning circuit plate detects that touch controlled key is depressed, the installation on gib arm of surperficial warning device.When the short warning circuit plate of crane short warning device occurs coming off or be loosening, spring is to the distress resolves of touch controlled key, and electric circuit inspection is pressed less than touch controlled key, and crane short warning device is by alert notice site operation personnel.
