Abstract
The present invention relates to a lifter which possesses the weighting, buffer, signal and lightning devices, and can distinguish that its lifting cage is empty or light-loaded or heavy-loaded, and possesses the functions of regulating its running speed and refusing to bear load under the condition of overweight. As compared with old-type lifting machine, under the condition of indentical electric consumption and identical working-hours its working efficiency can be raise by 2-3 times, it can reduce waste and can quicken engineering progress, and its operation is stable and smooth, and safety is reliable.
Description
The present invention is novel relate to a kind ofly can distinguish the cage of elevator sky, running velocity is regulated in light, heavy duty, arrive at the most at a slow speed, overweight refusing to take passengers, and be provided with weighing, buffering, signalling apparatus, the elevator of lightning protection belongs to mechanical up-to-date technology.
At present, known construction vertical transportation machinery has 2 kinds, and a kind of is building hoist, and another kind is a construction elevator.These 2 kinds of equipment have following common drawback except rising and falling 2 functions: 1, can not show number of floor levels, delay the time of cage to the stop of work floor that promotes; 2, can not show the lifting instruction, the operator can only listen manual calling to operate the lifting cage; 3, can not distinguish sky, light, heavy duty adjusting running velocity; 4, nothing arrives at the point of destination function the most at a slow speed; 5, the no overweight function of refusing to take passengers; 6, no weighing, buffering, signalling apparatus.
The later-model purpose of the present invention is the (improvement of my 96240537 patents, be dividing an application of 001191101 patent) provide a kind of load weight of distinguishing to regulate running velocity, when fast rise or decline, slow running function is arranged, the lifting cage is steadily arrived at, overweight refusing to take passengers, the elevator of weighing, buffering, signalling apparatus is established on the crane chassis.
The later-model purpose of the present invention is to realize like this; The mechanism that weighing, buffering, signalling apparatus, device inside have reflection weight is established in crane bottom; and by on circuit and the operator's station fast, middling speed, at a slow speed, low speed and the overweight signal head of refusing to take passengers join; operator's station is provided with convertible frequency control knob; rise, descend, stop and knob the most at a slow speed; the speed display lamp; the number of floor levels display lamp; lifting instruction display lamp; the overweight signal head of refusing to take passengers, variable-frequency governor, independent power source switch, low-tension transformer, relay, earth leakage protective device, connection box.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a general arrangement of the present invention.
