Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As Figure 1-3; a kind of protection device for over-speed ascending for elevator; protection device for over-speed ascending for elevator; including car body 1; counterweight 3, steel wire rope 4, and it is arranged on limiter of speed 7 and the traction machine 2 at elevator hoistways top; described steel wire rope 4 connects described car body 1 and counterweight 3, simple in construction by described traction machine 2.Described car body 1 is provided with safety tongs 5, and described steel wire rope 4 is provided with rope brake 6, and described traction machine 2 is provided with brake 8.Safety tongs, rope brake and brake are braked with the use of to the up elevator that exceeds the speed limit, elevator are served more preferable protective effect, improves the security performance of elevator.
Additionally, described safety tongs 5 include with cage guide with the use of caliper, described caliper includes the full symmetric left caliper 511 of planform and right caliper body 521, described left caliper 511 includes left lifting assembly, it is provided with left sliding shoe 514 on the right side of described left lifting assembly, on the right side of described left sliding shoe 514, is provided with left wearing layer 515.Described right caliper body 521 includes right lifting assembly, is provided with right sliding shoe 524, is provided with right wearing layer 525 on the left of described right sliding shoe 524 on the left of described right lifting assembly.The wear rate of safety tongs can be substantially reduced by wearing layer, extend the service life of safety tongs.Described left sliding shoe 514 and described right sliding shoe 524 top are respectively equipped with left trip rod 516 and right trip rod 526, can drive described left sliding shoe 514 and described right sliding shoe 524 upward sliding.
Described left lifting assembly include with described left sliding shoe 514 on the left of the left skateboard 513 that connects firmly, and left lifting parts 512 being connected with described left skateboard 513.Have on described left lifting parts 512 with described left skateboard 513 with the use of left chute.Be provided with bottom described left lifting parts 512 with made left skateboard 513 with the use of left spring.Described left sliding shoe 514 can with described left skateboard 513 together along left chute and with left spring with the use of upward sliding.
Described right lifting assembly include with described right sliding shoe 524 on the right side of the right slide plate 523 that connects firmly, and right lifting parts 522 being connected with described right slide plate 523.Have on described right lifting parts 522 with described right slide plate 523 with the use of right rail.Be provided with bottom described right lifting parts 522 with made right slide plate 523 with the use of right spring.Described right sliding shoe 524 can with described right slide plate 523 together along right rail and with right spring with the use of upward sliding.
Described safety tongs 5 at elevator under normal operation, is failure to actuate, and left sliding shoe 514 and right sliding shoe 524 are respectively positioned on bottom, now, has gap between left wearing layer 515 and right wearing layer 525 and cage guide.When the elevator car that breaks down quickly drops and time speed reaches the setting speed of limiter of speed, and limiter of speed starts, and safety tongs is started working.Safety tongs mentions left sliding shoe 514 and right sliding shoe 524 by left and right lifting assembly, left sliding shoe 514 and right sliding shoe 524 is made to be moved up along left lifting parts 512 and right lifting parts 522 by left skateboard 513 and right slide plate 523 respectively, until the medial surface of left wearing layer 515 and right wearing layer 525 clamps cage guide firmly, make lift car stop motion.Owing to left wearing layer 515 and right wearing layer 525 can be made up of carbon fiber, and carbon fiber is a kind of high-temperature fibre with high intensity and high-modulus, its thermal coefficient of expansion is little, good corrosion resistance, the wear rate making the elevator safety tongs when braking suddenly and guide rail is low, substantially prolongs the service life of guide rail and safety tongs.
It addition, described rope brake 6 includes folder rope drive mechanism, folder rope trigger mechanism and folder rope resetting-mechanism.Folder rope drive mechanism can clamping steel wire rope, it is achieved car stop.Folder rope trigger mechanism can accept elevator overspeed signal, causes folder rope drive mechanism action.Folder rope resetting-mechanism can make folder rope drive mechanism and folder rope trigger mechanism again reset after work completes.By described rope brake 6, the up elevator that exceeds the speed limit is braked, again improves the security performance of elevator.
It addition, described brake 8 includes clamping device, trigger mechanism and lock structure.Described trigger mechanism includes impacting assembly 81, brake cable assembly 82, reset assembly 83 and bearing assembly 84.Described impact assembly 81 includes that guide pillar and impact spring, described impact assembly 81 are compressed by described impact spring and is positioned at the arm-tie on described bearing assembly 84, and described brake cable assembly 82 is connected by screw and the arm-tie on described bearing assembly 84 are fixing.Brake cable is driven by external force, pulls arm-tie to slide to one end, makes impact assembly 81 lose support and down move, and under the effect of impact spring, it is achieved impact, reset assembly 83 is fixing with arm-tie to be connected, and promotes arm-tie to reset by back-moving spring.By described brake 8, the up elevator that exceeds the speed limit is braked, further increases the security performance of elevator.
The advantages such as it is high that this utility model one protection device for over-speed ascending for elevator has security performance, good braking effect.
