Description
Technical field
The present invention relates to elevator parts technical field, more particularly to a kind of rope head fixing device of elevator weighing apparatus.
Background technology
All employ elevator in places such as numerous big and middle markets, hotel, school, public place of entertainment, residential buildings, elevator it is general
And the life undoubtedly given people brings great convenience, many valuable times are saved.Among the operation of elevator, elevator
Weighing device and rope head fixing device are extremely important for the safe operation of elevator.
Weighing device of the prior art mainly has two kinds, and a kind of is the structure using microswitch, passes through rope hitch plate pressure
Contracting rubber, rubber compress variation touches microswitch when reaching certain value and realizes alarm, but the compress variation of rubber only has
Certain value, this mode detection sensitivity is low, does not reach the requirement accurately measured；Another is to use pressure sensitive structure, not
In mobilizable car floor elevator, the pressure that rope hitch plate is provided is transferred to dress of weighing by way of pressure sensor is with electric signal
Put, the signal is transferred to mainboard by weighing device in the way of data signal again, so as to judge whether elevator overloads.Pressure sensing
The debugging of device and the self study of weighing device often bring very big puzzlement to installation personnel, and weighing device needs specially
The timing debugging of industry personnel, ensures the accurate weighing data of pressure sensor, otherwise elevator can often report the failure in double recipe face,
The service efficiency of elevator is influenceed, and such a weighing device cost is higher, is unfavorable for the competition of market economy.Additionally, due in car
Number it is different and a variety of causes can cause car discontinuity so that the magnet installed in cage bottom is easily tilted,
Function of weighing can not thus be realized.
In the prior art, rope hitch plate fixed beam is typically directly weldingly fixed on spandrel girder, in running process of elevator, steel
Cord can produce certain vibration, and the stability tool run to elevator has a certain impact, and can produce at fag end noise,
Influence the boarding impression of people.
Such as Application No.：201610379118.9 Chinese patent disclose a kind of elevator weighing apparatus, including fixation
The fixation rope hitch plate (1) of setting and the movable rope hitch plate (2) above fixed rope hitch plate (1), it is characterised in that described consolidates
Determine to be provided with some hitch rods being parallel to each other (3) between rope hitch plate (1) and movable rope hitch plate (2), hitch rod (3) perpendicular to
