Description
Technical Field
The utility model relates to the technical field of elevator equipment, in particular to an elevator speed limiter transmission mechanism.
Background
At present, the elevator industry mainly adopts a transmission structure that a steel cable drives a speed limiter, and as shown in figure 1, the transmission structure mainly comprises a steel cable 1, a bracket 2, a pulley 3, a switch 4, a balancing rod 5, a steel cable tensioning counterweight 6 and an elevator horse 7; the working principle is as follows: the elevator car drives the steel cable transmission, and the steel cable drives the overspeed governor and rotates, triggers the overspeed governor brake when elevator speed surpasses overspeed governor design speed. The steel cable is tensioned by the balancing rod and the tensioning balancing weight, the switch is arranged below the balancing rod, the switch is triggered after the steel cable is broken or loosened, the power supply of the elevator motor is disconnected, and the safety work of the speed limiter is guaranteed. However, the speed limiter structure is large in size, complex in structure, high in cost, small in application range and particularly not suitable for small elevators, such as household small elevators, and occupies a large installation space.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an elevator speed limiter transmission mechanism which is reasonable in structural design and low in cost.
In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides an elevator overspeed governor drive mechanism, includes support, elastic component, switch, movable cover, goes up to press from both sides tight piece, lower clamp tight piece, hold-in range, the movable cover is located on the support, the one end of movable cover is passed through the elastic component and is connected with the bottom of support, form an accommodation space between movable cover and the support, be equipped with the switch in the accommodation space, the other end of movable cover is connected with the hold-in range, the hold-in range is connected with the movable cover through last clamp tight piece, the other end of hold-in range is fixed by lower clamp tight piece.
Furthermore, a contact piece for starting the switch is arranged on the movable cover.
Further, the elastic member is a tension spring.
Furthermore, the bracket and the movable cover are correspondingly provided with through grooves, and the bracket and the movable cover are movably connected through a fixing piece.
In the transmission mechanism, the synchronous belt is tensioned by the tensioning spring, so that the belt is always in a tensioning state, and if the belt is loosened or broken, the tensioning spring can pull the movable cover to move downwards, so that the contact piece on the movable cover starts the switch, the power supply of the elevator motor is disconnected, the elevator stops running, and the safe running of the elevator is protected.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, but the technical solutions do not limit the scope of the present invention.
Referring to fig. 1-4, an elevator overspeed governor drive mechanism, including support 1, elastic component 2, switch 3, movable cover 4, go up and press from both sides tight piece 5, press from both sides tight piece 7 down, hold in range 6, wherein, movable cover 4 is located on support 1, the one end of movable cover 4 is passed through elastic component 2 and is connected with the bottom of support 1, form an accommodation space between movable cover 4 and the support 1, be equipped with switch 3 in this accommodation space, the other end of movable cover 4 is connected with hold in range 6, hold in range 6 is connected with movable cover 4 through last pressing from both sides tight piece 5, the other end of hold in range 6 is pressed from both sides tight piece 7 by lower and is fixed.
Specifically, the movable cover 4 is provided with a contact piece for starting the switch 3.
Preferably, the elastic member 2 is a tension spring.
Concretely, logical groove has all been seted up to what correspond on support 1 and the movable cover 4 to through mounting with support 1 and movable cover 4 swing joint, personnel in this field also can adopt other modes swing joint according to actual need.
The transmission structure mainly comprises a bracket, a tension spring, a switch, a movable cover, a lower clamping block, a synchronous belt and an upper clamping block. The working principle is as follows: the upper clamping block of the synchronous belt is installed on the uppermost surface of the elevator frame, the lower clamping blocks of the support and the lower clamping block of the synchronous belt are installed on the lowermost surface of the elevator frame, the synchronous belt is fixed at the upper end and the lower end of the elevator through the upper clamping block and the lower clamping block, the speed limiter installed on the elevator car is driven to rotate through the synchronous belt, the speed limiter can be triggered to work when the speed of the elevator exceeds the designed speed of the speed limiter, the elevator can be braked through the brake block, and meanwhile, the power supply of a motor of the elevator is disconnected. The hold-in range is taut by the tensioning spring, guarantees that the belt is in the tensioning state all the time, if the belt takes place not hard up or fracture, and the tensioning spring can stimulate the movable cover downstream to lead to the contact starting switch on the movable cover, disconnection elevator motor power makes the elevator stall, protection elevator safe operation.
In conclusion, the transmission structure is simple, the size is small, the installation is convenient, and the cost is low. Meanwhile, the synchronous belt is adopted for transmission, so that the transmission is accurate and reliable, and parts such as a steel wire rope, a pulley and the like are not additionally arranged, so that the failure rate is indirectly reduced; meanwhile, the maintenance is simple.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
