Description
Technical field
The present invention relates to a kind of arrester cover of elevator hoist, especially relate to a kind of arrester cover of following elevator hoist, its drg to the electrical motor that is arranged on the hoist trunk bottom has water-proof function.
Background technology
Arrester cover as traditional elevator hoist, a kind of arrester cover that covers brake equipment is for example disclosed in the patent documentation one, the end face of this arrester cover and motor body, the edge that is motor body is close together, when flood etc. taking place cause the bottom water inlet of hoist trunk, the winch that can play being arranged on the bottom carries out waterproof effect, and the drg that especially can play winch carries out waterproof effect.
In addition, as traditional technology, also having a kind of is that the arrester cover that will be used to cover brake equipment is divided into two parts up and down, and the end face of each cover and the edge of electrical motor are linked together closely, and another end face and another cover link together closely.
Patent documentation one: WO2000-46139 communique
But, there is following problem in the former arrester cover, because this arrester cover is one-piece type, so when maintaining operation etc. and needing the direct contact drg, must the arrester cover dismounting be taken out from side direction, therefore need broad working space, and in narrow hoist trunk, be difficult to carry out above-mentioned operation.
In addition, the latter's arrester cover is owing to be divided into up and down two parts, so when maintaining operation etc., for example upper lid up can be pulled down taking-up separately, therefore has good operation.; arrester cover is played a protective role to drg when water inlet; air-tightness is an important factor; from this point; need the end face of divided each cover and the edge of electrical motor are linked together closely; and another end face and another cover linked together closely therefore existing problems aspect air-tightness.
Summary of the invention
The present invention be directed in the above-mentioned conventional art existing problem and make, the object of the present invention is to provide a kind of arrester cover of elevator hoist, this arrester cover not only has good working, but also can guarantee air-tightness.
To achieve these goals, the arrester cover of the elevator hoist in first invention of the present invention has following structure, the elevator hoist drg that has electrical motor and this electrical motor is braked wherein, this electrical motor is set in place in the elevator hole of hoist trunk bottom, drive the rope sheave that is wound with the hoist cable that is used to make the lift car lifting on it, described arrester cover is installed on the flange of described electrical motor, be used to cover described drg, wherein, this arrester cover has lower cover, middle plate and upper lid, the side that described lower cover is fixed to its end face and described flange is close together, be used for covering the below of described electrical motor, the lower surface of plate and the upper surface of described lower cover are close together in the middle of described, and the side of its end face and described flange is close together, the upper surface that described upper lid is fixed to its lower surface and described middle plate is close together, and is used for covering the top of described drg.
In first invention of the present invention with structure like this, the side that lower cover is fixed to its end face and flange is close together, the lower surface of middle plate and the upper surface of lower cover are close together, and the side of its end face and flange is close together, and the upper surface that upper lid is fixed to its lower surface and middle plate is close together.Thus, when maintenance waits, only need past top that upper lid is pulled down separately and just can.In addition, the upper lid of main disengaging section during as operation, because it only combines with the upper surface of middle plate, and middle plate when operation, need not pull down and and keep being close to state between the flange always, so with traditional between each cover and the edge side and with another cover between have two faying faces altogether the Splittable arrester cover compare, keep air-tightness easily.
In addition, the arrester cover of the elevator hoist in second invention of the present invention has following structure, promptly is provided with rubber sheet gasket between described middle plate and described upper lid.
In second invention of the present invention with structure like this, owing between middle plate and upper lid, be provided with rubber sheet gasket, so can guarantee higher air-tightness.
(invention effect)
According to the present invention, because arrester cover adopted the Splittable structure, all have good working, work such as can maintain in narrow hoist trunk expeditiously.
In addition, the upper lid of main disengaging section during as operation because it only combines with the upper surface of middle plate, therefore can be kept air-tightness, more easily so can further improve the waterproof effect to drg.
And,,, can further improve waterproof effect to drg so can guarantee higher air-tightness owing between middle plate and upper lid, be provided with rubber sheet gasket.
