The elevator safety device is scientific and reasonable in design, simple in structure and easy to implement, an elevator car is protected in real time in the vertical operation process of the elevator car, the falling and sudden ascending probability of the elevator car is lowered, and elevator safety is improved.
Description
Technical field
The utility model relates to elevator safety technical field, is specifically related to a kind of elevator car safety.
Background technology
Be accompanied by the development of urban construction, and the raising of people's quality of life, when resident trip can be enjoyed good land Public Transport Service, also thirst for obtaining vertical transportation easily in house.Therefore, in recent years, the quantity rapid growth of residential lift.Residential lift is common people's requisite walking-replacing tools of going on a journey as a kind of special vehicle, bring unprecedented convenience to the people's daily life, the safety of its operation, reliability are the problems that a lot of people are generally concerned about, residential lift quality, directly affects common people's quality of life.Therefore residential lift is subject to people's close attention especially.
Because residential lift manufacture, installation market competition grow in intensity, the expansion of the elevator market demand in recent years, need lift-mounting quantity sharply to increase, but the elevator safety event serious threat constantly occurring is to user's life security, time have the elevator safety accident of what is heard to make people all of jump.
Elevator is as vertical transportation equipment, or because parts wear, or because there is breakdown of equipment unavoidable in the inopportune operation in installation and maintenance process.But the generation of elevator safety accident is often relevant with the wrong mode of thinking and processing method for elevator faults.Different from disaster, elevator safety accident is not random generation, but people's the wrong mode of thinking and aberration cause.Therefore, at present except periodical maintenance maintenance, go back the good method of neither one and solve the problem of elevator safety hidden danger.
Summary of the invention
The purpose of this utility model is to provide a kind of elevator car safety, and its design science is reasonable, simple for structure, in the process of moving up and down, it is carried out to real-time guard at lift car, has reduced the probability that car falls and rushes to summit, and improves the safety of elevator.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises a pair of perforated support plate, several flexible rod irons, the spring equating with flexible rod iron quantity, retainer guide rail, a pair of retainer, retainer lifting rope, motor, a pair of perforated support plate is vertically set up in parallel, and the through hole on it is corresponding one by one, wherein the right side of a perforated support plate is vertically installed with retainer guide rail, on retainer guide rail, be combined with a pair of retainer by retainer lifting rope, between retainer lifting rope and another perforated support plate, be evenly horizontally disposed with the flexible rod iron of several activities, and flexible rod iron is located in through hole corresponding on a pair of perforated support plate successively, flexible rod iron outer wall between perforated support plate and retainer lifting rope is socketed with spring, and the right-hand member of spring and flexible rod iron is fixed, the lower end of retainer lifting rope is connected with the clutch end of motor.
Described retainer matches with the two ends up and down of car.
Principle of the present utility model is: safety device is arranged on a side of hoistway, when car moves up and down, driven by motor retainer is synchronizeed up and down operation on retainer guide rail in hoistway with car, in operational process, retainer institute together eject together with spring through the flexible rod iron of part, prevent car drop or rush to summit.After retainer is removed, flexible rod iron resets under the effect of spring force.
The utility model design science is reasonable, simple for structure, in the process of moving up and down, it is carried out to real-time guard at lift car, has reduced the probability that car falls and rushes to summit, and improves the safety of elevator.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model,
Reference numeral: the first perforated support plate 1, flexible rod iron 2, the second perforated support plate 3, spring 4, retainer guide rail 5, retainer 6, retainer lifting rope 7, motor 8, traction lifting rope A, hoistway B, car C.
Detailed description of the invention:
With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: it comprises the first perforated support plate 1, flexible rod iron 2, the second perforated support plate 3, spring 4, retainer guide rail 5, retainer 6, retainer lifting rope 7, motor 8, the first perforated support plate 1 is with second perforated support plate 3 is vertical is set up in parallel, and the through hole on it is corresponding one by one, the second perforated support plate 3 right sides are vertically installed with retainer guide rail 5, on retainer guide rail 5, be combined with a pair of retainer 6 by retainer lifting rope 7, between retainer lifting rope 7 and the first perforated support plate 1, be evenly horizontally disposed with the flexible rod iron 2 of several activities, and flexible rod iron 2 is located in the first perforated support plate 1 successively, on the second perforated support plate 3 in corresponding through hole, flexible rod iron 2 outer walls between the second perforated support plate 3 and retainer lifting rope 7 are socketed with spring 4, and spring 4 is fixed with the right-hand member of flexible rod iron 2, the lower end of retainer lifting rope 7 is connected with the clutch end of motor 8.
Described retainer 6 matches with the two ends up and down of car C.
The principle of this detailed description of the invention is: car C is vertically set in hoistway B by traction lifting rope A, safety device is arranged on a side of hoistway B, when car C moves up and down, motor 8 is by the 7 positive and negative rotations of coiling retainer lifting rope, thereby drive retainer 6 to synchronize up-and-down movement with car C along retainer guide rail 5, in the process of motion, retainer 6 eject together with spring 4 through the flexible rod iron 2 of position, make flexible rod iron 2 pass the first perforated support plate 1, the upper and lower side of car C is carried out spacing, effectively prevent that car C from falling and rushing to summit.After retainer 6 is left, the flexible rod iron 2 being ejected by it resets under the elastic force effect of spring 4.
This detailed description of the invention design science is reasonable, simple for structure, in the process of moving up and down, it is carried out to real-time guard at lift car, has reduced the probability that car falls and rushes to summit, and improves the safety of elevator.
