(54) УСТРОЙСТВО ДЛЯ ИСПЫТАНИЯ ЛОВИТЕЛЕЙ КАБИНЫ ЛИФТА(54) DEVICE FOR TESTING CATCHEERS OF ELEVATOR CABINS

II

Изобретение относитс к подъемно-транспортному машиностроению, в частности к устройствам дл испытани ловктелей кабины лифта.FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, in particular, to devices for testing elevator car tilters.

Известно устройство дл испытани ловителей кабины лифта, содержащее смонтированный на т ге дл подвески кабины удерживающий элемент с зубом, взаимодействуннций .с поворотным крю ком Q 1.A device for testing elevator cabin catchers is known, which comprises a retaining element mounted on a car suspension rod with a tooth, which interacts with a rotary hook Q 1.

Недостатками устройства вл ютс больша трудоемкость выполнени ручных работ, особенно при испытании кабин лифтов большой грузоподъемности; бокорое воздействие на крюк при сбрасьшанки, вследствие чего после сбрасывани крюк раскачиваетс , удар сь о стенки шахти, и поврезкдает аппараты, шунты, датчики и другое , оборудование шахты лифта; необходимость заводки крюка сбоку, что практически исключает возможность автоматического захвата кабины устройством.The drawbacks of the device are the large laboriousness of performing manual work, especially when testing high-capacity elevator cars; side effect on the hook when slinging off, as a result of which, after dropping, the hook sways, hitting the walls of the shaft, and cuts the devices, shunts, sensors and other equipment of the elevator shaft; the need to hook the side, which virtually eliminates the possibility of automatic capture of the cab device.

Цель изобретени - повышение эф фективности путем обеспечени автоматизаи ,ии управлени устройством.The purpose of the invention is to increase efficiency by providing automation and control of the device.

Цель достигаетс тем, что устройство снабжено размещенным на т ге грузом и вторым поворотным крюком, а удерживающий элемент вьтолнен в виде электромагнита, корь которого расположен между скосами, вьшолненными на крюках, при этом на верхнем конце т ги выполнена скоба дл грузоподъемного механизма, а на нижнем наконечник , св занный с рычагами, шарнирно закреппенШ)СМИ на кабине и соединенными между собой пружиной, при этом нижн часть груза вьталнена в форме усеченного конуса, взаи|Модействующего в рабочем положении |с упом нутыми рычагами.The goal is achieved by the fact that the device is provided with a load and a second swivel hook placed on it, and the holding element is made in the form of an electromagnet, the measles of which is located between the bevels carried out on the hooks, while the lower tip connected to the arms pivotally fixed the media on the cab and interconnected by a spring, while the lower part of the load is inserted in the shape of a truncated cone interlocking | Moderated in the working position | AGAMI.

Claims

Ya figure 1 shows the device in the initial position, a general view: in figure 2 - the same, in the working position. 3. The device contains a tug 1, a new bracket 2 hanging on the hook of the load-lifting mechanism, an electromagnet 3 clamping to the bracket 3 with a cowl 4, located on the load, the load 5 is suspended with the help of b, which have a bevel. In the lower part of the tipper 1 BbirtejiHeH, tip 7, which is gripped by levers 8 with the aid of handles 9, Rwagis 8 are hinged on the elevator car 10 and are restrained by stops J1. The device works as follows. When power is applied to the core of the electromagnet 3, A is attracted to it by turning the hooks 6, removing them from the engagement with the electromagnet 3. Under the action of its own weight, the load 5 falls on the wide base of the tip 7, and the surface of the truncated cone 8. Cab 10 is released from engagement with pull 1 and falls. Tests of elevators with the help of the proposed device allow remote control of the process from the lift of the elevator car and ensure the safety of testing. Claim device for testing elevator cabin catchers, containing an element with a tooth mounted on a cab suspension rod with a swiveling hook, characterized in that, in order to improve efficiency by ensuring automation of device control, it is provided with a load of space and the second swivel hook, and the holding element is designed as an electromagnet, the measles of which is located between the bevels, hanged high on the hooks, while at the upper end of the tie a bracket for a lifting mechanism, and on the bottom a tip connected to the lever, jarn-mounted on the cab and connected between the spring, while the lower part of the load is made in the form of a truncated cone, which interacts in the working position with the said levers.
