Description
Technical field
The present invention relates to a kind of brake equipment of elevator, when especially relating to a kind of rising or falling speed and having surpassed specified value, perhaps when lifting body goes, use the brake equipment of the elevator that actuator brakes this lifting body under no-console condition at lifting body.
Background technology
Brake equipment as the elevator that uses actuator that lifting body is braked; Possess actuator and brake component; Said actuator has the action force that overcomes elastic force; And under defined terms, be disconnected power supply, said brake component stops the lifting body deceleration corresponding to the power supply disconnection of this actuator and under the effect of elastic force with the guide rail moving contact.And when having surpassed specified value as the rising or falling speed at lifting body, the mechanism of perhaps when lifting body goes under no-console condition, lifting body being braked uses the device that has used such actuator.
But, in above-mentioned brake equipment, lifting body is stopped in order to make brake component and guide rail moving contact through elastic force; Need elastic force be set in more than the certain value degree, and, can cruising in order to make lifting body; Needing to have elastic force effect brake component above that to remain on open state all the time, so actuator must have the action force that can overcome elastic force, for this reason; Need to increase the capacity of actuator, thereby existence can cause problems such as brake equipment maximization and establishment charges increase.In addition,, then need fully guarantee the gap between brake component and the guide rail, and will accomplish this point, then need further to strengthen the capacity of actuator if use actuator with the attractive force that can overcome elastic force.
For this reason; For example can consider to adopt patent documentation 1 described brake equipment, be provided with the brake component and the holder of wedge-like in this brake equipment, the friction force that the brake component of this wedge-like is produced when being pressed against on the guide rail; Lifting body descend when moving towards above move; And lifting body rise when moving towards below move, be formed with 2 dip plane that constitute the V-shape side view on this holder, brake component is clamped between this holder and the guide rail.In addition; This brake equipment also has the independent action that constitutes and uses elastic body with elastic body and braking; This action makes brake component towards braking position direction move through pitman with elastic body when the power supply of actuator is disconnected, and this braking applies pressing force and obtains suitable braking force to the brake component with the guide rail moving contact with elastic body.This brake equipment can reduce action and use elastomeric elastic force, thereby can reduce the capacity (for example with reference to patent documentation 1) of actuator through adopting said structure.
The patent documentation 1 open patent 2007-277013 of Japan communique (paragraph numbering 0029～0035, Fig. 5)
But, in above-mentioned prior art, actuator is installed owing to adopted at an end of pitman; The structure of brake component is installed at the other end; So in the both sides of lifting body, carry out glancing impact at brake equipment, the antagonistic force that brake component is produced when being sandwiched between guide rail and the holder forms the pressing force that lifting body is pushed towards the direction of leaving guide rail; And form the pressing force that guide rail is pushed towards the direction of leaving lifting body; Thereby lifting body is distorted, perhaps makes the installation site of guide rail that skew etc. takes place, so unsatisfactory.
In addition,,, need guarantee braking with elastomeric flexible so exist in order to bring into play required braking force owing to only be provided with movable brake component one-sided, thus the problem that can cause device to maximize.In addition; Also can consider to use the high braking of spring constant to use elastic body; Make and under the little situation of deflection, also can guarantee necessary braking force; But when this method of employing, also can bring influence very greatly, therefore need carry out strict control the size of various piece to braking force because very little deflection changes.
