Description
Technical Field
The invention belongs to the field of elevators, and particularly relates to a simple elevator overspeed self-locking guide shoe mechanism, in particular to a guide shoe structure capable of performing self-locking when an elevator overspeed operation occurs.
Background
With the development of social economy, the maintenance amount of elevators is increasing, and the safety of elevators is attracting increasing attention. Conventional elevator safety devices include brakes, speed limiters, safety clamps, buffers, and the like. The speed limiter and the safety tongs are main components for stopping when the elevator overspeed, and form a device for rapidly stopping the car together. Typically, the speed limiter is installed in a machine room, safety tongs are installed on both sides of the car, and they are connected by a wire rope and a tie rod. The disadvantage of the speed limiter and the safety gear components is that the linkage action of the speed limiter and the safety gear components needs to be carried out through a steel wire rope, and when the elevator overspeed falling triggers the sudden stop of the speed limiter, the speed limiter can rotate negatively, so that the stopping action of the safety gear is disabled. In addition, the structure of the safety tongs can cause flaws to be left on the guide rail after emergency stop, and the surface of the guide rail is damaged. Other existing elevator overspeed falling protection devices are also generally installed at a position far away from the elevator car, the running of the elevator car is protected in an indirect mode, and structural optimization can be performed on a guide shoe structure directly connected with the elevator car for further improving the overall safety performance of the elevator.
The guide shoes are arranged on the car frame and the counterweight device, so that the car and the counterweight device run along the guide rails. Guide shoes connected with the car are distributed on two sides of the car and are in direct contact with the guide rails, and the guide shoes have the function of preventing the car and the counterweight from deflecting or swinging during the running process. The traditional guide shoe structure only has the guiding function and does not have the emergency stopping function.

The arrangement of the structure enables the centrifugal block to move in the centrifugal block guide groove. During normal operation of the elevator, the shortest distance between the centrifugal block guide groove 412 and the push rod 5 is less than half the length of the centrifugal block 414. When the elevator reaches the critical speed to be overspeed, the outer end surface of the centrifugal block 414 away from the central axis of the side guide wheel 4 coincides with the outer end surface of the centrifugal block guide groove 412 away from the central axis of the side guide wheel 4 under the action of centrifugal force.
The side tightness adjusting assembly comprises a side guide rod 144, a side wheel arm compression spring 46, a side wheel arm compression gasket 47 and a side wheel arm compression screw 48, wherein the side guide rod 144 is connected to a side base support and provided with a side limiting plate 143, the side wheel arm compression spring 46, the side wheel arm compression gasket 47 and the side wheel arm compression screw 48 are sequentially sleeved on the side guide rod from bottom to top, the side guide rod passes through the side positioning wheel arm baffle, and two ends of the side wheel arm compression spring respectively abut against the side positioning wheel arm baffle and the side wheel arm compression gasket.
The side wheel arm compression spring, the side wheel arm compression gasket and the side wheel arm compression screw enable the side positioning wheel arm baffle to lean against the side limiting plate along the side guide rod on the side base support on the base, so that the side guide wheel is driven to lean against the guide rail. One end of the side guide rod on the side base support is provided with a thread, so that the side wheel arm compression screw can adjust the tightness of the side guide wheel leaning against the guide rail.
The side guide rod is an inclined guide rod penetrating between the two side wheel arms, and the side positioning wheel arm baffle is at least fixedly connected with one side wheel arm.
The left and right guide wheels are connected with the left and right positioning wheel arms 24 through upper left and right bearings 22 and upper connecting shafts 23, the side guide wheels are connected with side wheel arms 44 through upper side bearings 42 and side upper connecting shafts 43 through side guide wheels 4, the bottom ends of the side wheel arms are connected with the base through supports 15 arranged on the base and lower connecting shafts 151 penetrating through the supports, and the bottom ends of the side wheel arms are connected with the base through side supports 17 arranged on the base and side lower connecting shafts 171 penetrating through the side supports.
Embodiment III:
the difference from the above embodiment is that the hollow groove is a curved groove, the diameter of which gradually decreases from one end to the other end, and the diameter of one end with the smallest diameter is not smaller than the diameter of the cylindrical buckle, so that the cylindrical buckle 61 can be smoothly buckled into the hollow groove. The guide rail is a T-shaped guide rail.
In the case of normal non-overspeed fall of the elevator, the centrifugal shoe 414 in the centrifugal mechanism 41 is restrained in the centrifugal shoe guide groove 412 by the speed adjusting spring 413, and its end face does not protrude from the centrifugal shoe guide groove 412. The connecting rod 6 is contacted with one side of the push rod pulling piece 51 of the push rod 5, the other side is contacted with the push rod guiding groove 11, the push rod pulling piece can be connected with the push rod or the connecting rod, the connecting rod and the push rod 5 are in a static state under the limiting action of the return spring 62, and the cylindrical buckle 61 of the connecting rod keeps a certain distance with the left guiding wheel and the right guiding wheel.
When the elevator drops at overspeed, the side guide wheels 4 will rotate at high speed, and when the restraining force provided by the speed adjusting spring 413 is far smaller than the centrifugal force acting on the centrifugal block 414, the centrifugal block 414 will move away from the axle center of the side guide wheels 4 along the centrifugal block guide groove 412, and then the centrifugal block will trigger the push rod 5 to drive the connecting rod to move left and right guide wheels. The cylindrical buckle 61 will buckle into the hollow groove on the left and right guide wheels 2, then, the sliding rotation of the left and right guide wheels 2 will pull the cylindrical buckle 61 to move upwards, under the leverage of the connecting rod shaft 1221, the connecting hole 65 at the other end of the connecting rod 6 will pull the positioning wheel arm connecting rod 2411 to lean against the guide rail 7, and then drive the left and right guide wheels 2 to lean against the guide rail 7, and the left and right guide wheels 2 stop. The falling movement of the elevator is prevented, because a self-locking is formed between the rotation and clamping of the two symmetrical left and right guide wheels in the guide shoe structure, and a symmetrical clamping is formed for the rail 7.
