Description

High building bulb fitting unit

The utility model relates to electrician's specific purpose tool, particularly changes the loading and unloading device of high-rise bulb.

High-altitude illuminating lamp fracture of wires such as higher workshop, hall and the square of floor height, road need be changed bulb later on, can or use ladder by hydraulic elevating platform.Therefore the oilhydraulic engineering car is only adopted in urban operating mechanisms such as street street lamp because investment is big morely, and general unit all uses ladder.Use ladder owing to there is very big unsafe factor, therefore many applying units and individual have thought many ways on the bulb handling instrument, most typical have: " lamp replacer " that China Patent No. 88202572.4 is designed by comrade Zhao Mingquan by " the electronic replacer of high-altitude illuminating lamp " and the China Patent No. 88215217.3 of comrades such as Gao Jiajun design.The common feature of these two kinds of instruments is: action bars can stretch as required, and the former calvus is a cassette, and screwing or unscrewing bulb employing electrical micro-machine is power, and its problem is: because the calvus aperture can not be controlled, influence clamping degree because of bulb-shaped difference easily; Simultaneously,, use motor both to increase the cost and the weight of instrument, make structure complicated again because the bulb screw thread only needs several circles just can realize loading onto or unloading.The latter's calvus is a normally closed type, the shape of calvus can be changed as required, improved the reasonability when using, but problem is: because the calvus aperture adopts backguy control, when highly higher, to aim at bulb, backguy again on the other hand on the one hand, it is very inconvenient to operate, and often is difficult for unscrewing bulb owing to the problem of calvus structure and rigidity aspect causes.

The purpose of this utility model: be to overcome the deficiency of above-mentioned bulb loading and unloading device and design a kind of rational in infrastructurely, use reliable, easy to operate manual bulb loading and unloading device.

Technical solution of the present utility model is: adopt the simple and easy manipulator of loading and unloading bulb special use, comprising: pawl head, action bars, controller and folding and unfolding drum.

1. pawl head.Comprise: the dish-shaped calvus that is hinged more than (1) two, in order to catch bulb, in order to make its existing enough frictional force, do not make the bulb fragmentation again, therefore, the shape of calvus is consistent with the bulb curved surface, skin is metal or plastics forming, and the inboard is that flexible plastics or rubber are pasted; (2) switching of calvus drives the controlled line traffic control of connecting rod by the connecting rod that is hinged on the calvus outside.

2. action bars.Form by up-thin-low-thick more piece hollow stem, adopt the locker that is threaded between two joints.At ordinary times, smaller diameter rods is linked in the major diameter bar, as required height is pulled out and threaded together during use.

3. controller.Be contained on the nethermost joint action bars, it comprises the fixedly dog screw and the fine setting vertical rod screw thread control handle highly of control line, and it also is equipped with the folding and unfolding drum that torsion spring is housed down.

Adopt the bulb loading and unloading device of technique scheme, overcome the deficiencies in the prior art, and had reliable, laborsaving, highly easy to adjust, the cheap for manufacturing cost advantage of loading and unloading bulb.

The utility model is described in further detail below in conjunction with embodiment:

Fig. 1 is bulb loading and unloading device structure chart.

1-dish calvus, 2-connecting rod, the "T"-shaped axle of 3-, 4-bearing support, 5-stage clip, 6-connector, 7-action bars, 8-locker, 9-control handle, 10-dog screw, 11-folding and unfolding drum, 12-control line.

Fig. 2 is the locker and the control handle enlarged drawing of bulb loading and unloading device.

Fig. 3 is the pawl head and the action bars annexation schematic diagram of bulb loading and unloading device.

13 are top connection among the figure, and 14 are lower contact.

Three dish-shaped calvus 1 are housed on the pawl head as figure, calvus is hinged on the upper bottom surface of support 4, one end of connecting rod 2 and the outside of calvus 1 are hinged, the other end and "T"-shaped axle 3 are hinged, the column of "T"-shaped axle cooperates with the hole, garden in the middle of the support bottom surface is movable, control line 12 links to each other with the column lower end of "T"-shaped axle, and extends to folding and unfolding drum 11 by action bars 7 always.In order to make calvus be in normally off at ordinary times, "T"-shaped axle column outside cover is with stage clip 5, and the stage clip lower end extends into interior certain end face of bottom surface of bearing support (4), makes stage clip that better guide-localization hole seat be arranged.

Action bars is the up-thin-low-thick aluminium alloy thin-walled bar of more piece fit, adopts screwed locker 8 to connect between two joints.

The opening controller of calvus is installed on next joint of action bars, comprises: control line dog screw 10, screwed control handle 9 and the folding and unfolding drum 11 that torsion spring is housed.

Adopt connector between pawl head and the action bars, connect with bi-directional movable with screw.

Usually, make calvus 1 be in normally off by stage clip 5 by connecting rod 2.

When need loading and unloading bulb, at first, adjust the height of action bars 7, then, screw joint locker 8 screw threads, screw dog screw 10, make control line 12 fastening, rotate threaded control handle 9, action bars is extended to some extent, relatively make control line affect the lower end of "T"-shaped axle 3, make between action bars and the control line and produce relative motion, "T"-shaped axle overcomes the elastic force of stage clip, to bottom offset, drivening rod also outwards opens calvus, entangle the bulb that need unload after, the reverse rotation control handle, make calvus be in clamped condition, the rotary manipulation bar unscrews bulb screw mouth, unloads bulb.

The control handle that rotates about just can make the synchronous on-off action of calvus, thereby has grasping and loosen the function of bulb.

When pulling out action bars, because artificial power is emitted control line in drum, simultaneously, the torsion spring on the drum 11 has produced potential energy, after using end, during the shrinkage operation bar, relies on the potential energy of drum torsion spring, makes in the control line income dish.

Adopt connector between pawl head and the action bars and flexibly connect, make it rely on the effect of frictional force, both had stability with screw, have again certain about, the anteversion and retroversion rotating function, help the bulb loading and unloading.

Running into the base surface corrosion when serious, can on action bars, be provided with one with axial vertical boosting-rod, shirk moment to increase rotation.

For adapting to the bulb loading and unloading needs of different capacity, specification, the ad hoc pawl head of having counted plurality of specifications is so that change.

Utilize principle of the present utility model and structure, also can use it for aspects such as trees beta pruning.
