Detailed Description
The invention is further illustrated by the following examples:
as shown in fig. 1 and 2, the double-power doubling-up deceleration braking elevator is similar to a conventional elevator in structure and comprises a hoistway 1, a car 2, a main traction mechanism 3 and a counterweight 4, wherein the main traction mechanism 3 is assembled at the upper part of the hoistway 1. The difference of the elevator lies in that belt pulleys 31 are respectively assembled on two sides of the main traction mechanism 3 in a transmission manner, connecting blocks 21 are respectively assembled on two sides of the car 2 in a fixed and symmetrical manner, the two connecting blocks 21 are respectively connected with the counterweight block 4 through synchronous belts 5, belt teeth are arranged on the inner side of the synchronous belts 5, and the synchronous belts 5 are in transmission connection with the belt pulleys 31; the upper portion of 1 inner chamber of well is equipped with clamp splice 6, the left and right sides of clamp splice 6 is equipped with the chuck 61 that can press from both sides tightly to the intermediate motion of symmetry, the hold-in range 5 of car 2 one side is followed pass through in the middle of two chucks 61 of clamp splice 6, be located two sections hold-in range 5's of band pulley 31 lower part both sides opposite movement direction front tooth portion is relative, two the chuck 61 is just right the back of band pulley 31 both sides hold-in range 5. When the chuck 61 is clamped toward the middle, the chuck 61 clamps the teeth of the two oppositely moving synchronous belts 5.
When the double-power doubling-up speed-reducing braking elevator is used, the belt wheel 31 and the synchronous belt 5 are used for transmission, the belt wheel 31 and the synchronous belt 5 are meshed relatively without relative movement, so that the running distance of the car 2 can be accurately judged according to the rotation of the belt wheel 31, and thus when the car 2 is operated, a control circuit only needs to control the belt wheel 31 to select the rotating angle, the control structure is simpler, a special flat-layer inductor does not need to be assembled in the hoistway 1 aiming at the position of each layer, so that the overall cost of the elevator is greatly reduced, in addition, the structure design of the clamping block 6 can ensure that the clamping head 61 moves towards the middle to clamp the two synchronous belts 5 which move in opposite directions, as shown in figure 3, at the moment, the toothed belts on the inner sides of the two synchronous belts 5 are mutually crossed, so that great resistance is generated, and the synchronous belts are stopped, in the braking process, the braking effect is better due to the meshing of the teeth, and meanwhile, the synchronous belt 5 always moves to enable the synchronous belt at the braking position to be different synchronous belt sections, so that heat accumulation cannot be caused, and the braking is not easy to break.
In the specific design, as shown in fig. 1, two sides of the main traction mechanism 3 are respectively designed with a transmission shaft extending horizontally, the transmission shafts on the two sides are in synchronous transmission connection, and the belt pulleys 31 are respectively assembled on the transmission shafts. Therefore, only one transmission motor is used for carrying out synchronous transmission on the two belt wheels 31, the cost can be greatly saved, and the transmission synchronism is better.
In this embodiment, as shown in fig. 2 and 3, the clamping block 6 is of an electric structure, the side of the clamping block 6 is connected with a power generation wheel 62 through a bracket, the power generation wheel 62 is tightly pressed against the back of the synchronous belt 5, and when the synchronous belt 5 moves, the power generation wheel 62 is driven to rotate. The generated power of the generating wheel 62 needs to correspond to the moving speed of the synchronous belt, specifically, when the car 2 runs normally, the power of the generating wheel 62 cannot drive the clamping block 6 to run, when the synchronous belt 5 runs at overspeed, the car is also in an overspeed running state, and the running speed of the generating wheel 62 can drive the clamping block 6 to work. Due to the structural design, the clamping block 6 can automatically stop the car 2 when the car moves in an overspeed mode, an external power supply is not needed, the stop operation can be performed in a power-off state, and the use is safer.
In a specific design, as shown in fig. 3, two parallel rotating wheels 63 capable of rotating around an axis are respectively assembled on the inner sides of the chucks 61 on both sides, the axial direction of the rotating wheels 63 is perpendicular to the moving direction of the synchronous belt 5, and when the chucks 61 are clamped towards the middle, the rotating wheels 63 are tightly pressed against the back of the synchronous belt 5. Two rotating wheels 63 are designed on the chucks 61 on two sides of the clamping block 6, so that when the clamping block 6 is clamped by the chucks 61, more toothed joints are formed on the two sections of synchronous belts 5 moving in opposite directions, and the braking effect of the elevator is better. Meanwhile, the rotating wheel 63 can also be used as a tension wheel to ensure the tension state of the synchronous belt 5. In addition, the design of the rotating wheel 63 ensures that the stress of the chuck 61 of the clamping block 6 of the braking component mainly comes from the tension force of the synchronous belt 5 when the elevator is stopped, the stress is small, the influence of the vertical movement of the synchronous belt 5 cannot be caused, and the elevator is safer in use. And rolling friction is formed between the rotating wheel 63 and the synchronous belt 5, so that the abrasion and the heat generation are extremely small, and the service life of the clamping block 6 is longer.
In a specific design, as shown in fig. 3, an elastic rubber layer 64 is designed on the outer side of the runner 63. The rubber layer 64 is designed to enable the rotating wheel to be in elastic contact with the synchronous belt 5, so that when the lift car moves at an overspeed and the toothed contact of the synchronous belt 5 with two ends moving in opposite directions is achieved, the stress is gradually increased, the braking process of the lift car 2 is enabled to be a process of gradually increasing the force, the braking process is softer, people and goods in the lift car are protected, meanwhile, the braking loss of the synchronous belt 5 and other parts is smaller, and the service life of the elevator braking equipment is longer.
In a specific design, the clamping blocks 6 are respectively assembled on two sides of the hoistway 1. Like this can stop at both sides simultaneously when elevator car 2 out of control operation, the effect is better, also can guarantee the normal operating that stops at the system when a system stops the structure and became invalid.
As shown in fig. 1, the lower part of the hoistway 1 is equipped with an auxiliary traction mechanism 7, two sides of the auxiliary traction mechanism 7 are respectively equipped with a belt pulley 31, the connecting block 21 on one side of the car 2 is connected with the lower part of the counterweight 4 through a synchronous belt 5, and the synchronous belt 5 on the lower part is in transmission connection with the belt pulley 31 on the lower part of the hoistway 1. By the structural design, when the upper main traction mechanism 3 of the elevator breaks down, the elevator can be driven to run by the auxiliary traction mechanism 7, so that the operation is quickly recovered, and the work of the elevator is ensured.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is to be construed in all aspects and as broadly as possible, and all changes, equivalents and modifications that fall within the true spirit and scope of the invention are therefore intended to be embraced therein.
