Description
Technical Field
The invention belongs to the technical field of elevator safety control systems, and relates to an elevator safety protection device with a self-diagnosis function.
Background
Can set up the elevator guide rail unanimous with elevator traffic direction in the elevator shaft in the van-type elevator system, elevator guide rail's effect is on the one hand gives the direction to elevator operation, guarantee the stability that elevator car goes up and down, on the other hand when elevator car takes place the landing, elevator car can start the safety hook of self bottom, the safety hook realizes promptly preventing weighing down fixedly to elevator car through chucking elevator guide rail, therefore the reliability direct influence of elevator guide rail installation stability and elevator safety hook can whether guarantee personnel's safety when taking place to glide danger.
Most of the cases, the elevator guide rail is fixedly installed with the side wall of the elevator shaft through bolts or screws, but the bolts or screws are easy to vibrate and loosen during long-term use due to the fact that the elevator is in contact with the elevator guide rail during operation and continuously vibrates, and the bolts or screws can also seriously fall off or break due to metal fatigue. Therefore, on one hand, the vibration amplitude of the elevator guide rail at the position is increased, and the loosened and unsewn bolt can generate abnormal sound along with vibration and harm the running stability of the elevator. If the falling protector is clamped and fixed at the elevator guide rail where the bolt is loosened or falls off when the elevator falls down, the elevator guide rail is likely to bear the impact generated when the elevator is not stopped suddenly and decelerated, so that the falling protector is deformed and even separated from the side wall of the elevator shaft, and the life safety accident of a crisis worker is caused as a result.
Because the elevator guide rails frequently pass through the elevator guide rails of the various parts in the operating condition of the elevator, the elevator guide rails to be loosened are fixed firmly again, the loosened bolts need to be screwed down, even the bolts need to be replaced, and the corresponding personnel and devices need to spend a certain time. In addition to the fact that the location of the elevator damage may be anywhere on the guide rails of the elevator, it takes a lot of time for a person or a robot to look up and down along the guide rails, and it is therefore difficult to inspect and maintain the elevator in the operating situation.
At present, the existing elevator fault diagnosis and safety protection system does not have a technology which can frequently check the reliability of the fixation of an elevator guide rail at any time in the running state of the elevator, and further lacks a protection technology which can timely and emergently treat a part with loosened or fallen bolts in the running state of the elevator, and because the elevator is in some shopping malls, office buildings and other buildings which are in long-time business or running every day, the elevator has short idle time, the elevator can only be stopped to run after a long time, and the elevator is regularly checked and maintained, so the inspection and maintenance of the elevator guide rail in the prior art are often untimely, and the running safety of the elevator is greatly influenced.

During the process of nail-shooting fixing of the guide rail quick fixing device 8, the elevator car 1 still rises at the normal running speed, the upper arm rod 71 and the lower arm rod 72 of the extensible connecting structure 7 are unfolded during the process, the steel wire rope 731 of the elastic tensioning structure 73 is stretched, and the tension of the spiral spring acting on the tension sensor is increased along with the expansion of the spiral spring. When the rail quick-fixing device 8 is normally operated, the locking fixing mechanism is released before the extendable connecting structure 7 is fully extended, thereby allowing the extendable connecting structure 7 to pull the rail quick-fixing device 8 back to the initial position. If the locking and fixing mechanism is not loosened in time, when the tension sensor detects enough force, a signal is sent, the fixing device control module controls the locking and fixing mechanism to be opened, and the phenomenon that the locking and fixing mechanism is not loosened in time to affect the ascending of the elevator car 1 is avoided.
This scheme just has carried out interim reinforcement to elevator guide rail 2 through guide rail quick fixation device 8 at the in-process of elevator operation, can not only improve elevator car 1 immediately and move on this elevator guide rail 2, and when safety hook 3 card died elevator guide rail 2, elevator guide rail 2 has been consolidated so difficult emergence be out of shape and drop, has improved personnel's security in the above-mentioned accident greatly.
And in order to make the position that has consolidated in this scheme can repeat and consolidate fast, the structure that quick staple 9 and staple hole 23 that this scheme adopted correspond. The quick fixing nail 9 can be shot into the fixing nail hole 23, and the connection tightness of the quick fixing nail 9 is ensured through the clamping effect of the wedge-shaped bulge 94 and the ring groove. After the maintenance personal is screwed up or is changed the construction bolt 22 that becomes flexible or drops, under the prerequisite of having guaranteed the fixed fastness of elevator guide rail 2, only need to back out the interior screw 93 of quick fixation nail 9, the portion of can adduction that loses the support is adducted under self metal elasticity, lets the protruding 94 of wedge form break away from the annular to take out remaining outer nail body very easily, reservation through-hole and quick fixation nail 9 on the elevator guide rail 2 of this scheme can both used repeatedly like this.
The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution of the invention, or to apply the inventive concept and solution directly to other applications without modification.
