Description
Technical field
The present invention relates to a kind of elevator faults deliverance apparatus, be specifically related to the oppressive fault emergency rescue apparatus of a kind of machine-roomless lift.
Background technology
When the oppressive needs of machine-roomless lift et out of order are implemented rescue at present, be by control the action of electromagnetism pine band-type brake make lift car under the non-equilibrium state toward one party to slip the form of car move to flat bed after release passenger's mode carry out, characteristics simple to operate, easy enforcement that this rescue mode has can satisfy elevator fully oppressive rescue needs occur under non-equilibrium state and normal condition.But, when elevator is in balanced load state, extreme fault when the action of cage side safety tongs, underloading (during such as heavy duty to the action of heavy side safety tongs) or hoistway layer door opening structure when special, just be difficult to adopt above-mentioned rescue mode to implement rescue operation, be that the mode that adopts the sedan-chair top to add loads or people from station is removed state of equilibrium as a rule, or use chain block to promote the car rescue mode replies such as safety tongs that reset on the sedan-chair top.But all there is serious potential safety hazard in above-mentioned rescue mode, and then can't tackle when the situation that the rescue group can't enter sedan-chair top occurring, has a strong impact on the oppressive rescue efficiency of elevator faults.And according to the 64 of No. 549 " Safety Supervision on Special Equipment regulations " (2009-5-1 execution) of State Council Decree and the 88 regulation: lift car was detained personnel more than 2 hours, located fine below 200,000 yuan more than 100,000 yuan.At present, there is no actv. rescue mode and deliverance apparatus can address the above problem.
Summary of the invention
The object of the invention is to the deficiencies in the prior art part, provide a kind of cost low, safe, quick for installation, simple to operate, adapt to the oppressive fault emergency rescue apparatus of machine-roomless lift of various oppressive operating modes.
For achieving the above object, the present invention adopts following technical scheme:
The oppressive fault emergency rescue apparatus of machine-roomless lift comprises two folder rope assemblies, on the traction steel-cable that is clamped in respectively the traction sheave both sides; With the assembly that furthers, be connected between described two folder rope assemblies, press from both sides the distance between the center-point of rope assembly in order to further two.
As preferably, the clamped position of a folder rope assembly is higher than the clamped position of another folder rope assembly.
As preferably, the described assembly that furthers is chain block, and the hook of described chain block hooks the folder rope assembly that clamps the heavy side traction steel-cable, and the lower suspension hook of described chain block hooks the folder rope assembly that clamps the cage side traction steel-cable.Further, described chain block is the single-chain type chain block.
As preferably, described folder rope assembly comprises a hanging hole steel plate, which is provided with some screws and lateral surface thereof and is provided with the hanging hole that the suspension hook for chain block hooks; A screw steel plate which is provided with some screws, and its medial surface is relative with the medial surface of hanging hole steel plate; Two copper clamping plate are fixed by screws in respectively on the medial surface of hanging hole steel plate and screw steel plate and make the medial surface of two copper clamping plate relative, and the medial surface of every copper clamping plate is provided with the clip slot that traction steel-cable is clamped in some confessions; With some bolts, successively described hanging hole steel plate, two copper clamping plate and screw steel plate are serially connected.
The present invention is by adopting said structure, can eliminate the potential safety hazard that existing rescue mode exists, ensure greatly elevator passenger and operating personnel's personal safety, greatly improve the especially oppressive fault rescue efficient of mainframe lower formula machine-roomless lift of machine-roomless lift, and can satisfy national standard about the requirement of emergency operation.And the present invention is simple in structure, and the reply operating mode is wide, is easy to carry again, can tackle various emergency case, effectively strengthens the ability that the elevator maintain and protection personnel tackle emergency episode.

Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
The specific embodiment
As shown in Figures 1 to 4, the oppressive fault emergency rescue apparatus of machine-roomless lift of the present invention mainly is comprised of two folder rope assemblies 1 and a chain block 2.Described folder rope assembly 1 is comprised of a hanging hole steel plate 11, a screw steel plate 12, two copper clamping plate 13, some flathead screws 14 and some bolts 15.Hanging hole steel plate 11 is provided with some screws and lateral surface is provided with hanging hole 111.Screw steel plate 12 is provided with some screws, and its medial surface is relative with the medial surface of hanging hole steel plate 11.Two copper clamping plate 13 are fixed on the medial surface of hanging hole steel plate 11 and screw steel plate 12 by flathead screw 14 respectively, and the medial surface of two copper clamping plate 13 is relative, and the medial surface of every copper clamping plate is provided with the clip slot 131 that traction steel-cable is clamped in some confessions.Some bolts 15 are serially connected described hanging hole steel plate 11, two copper clamping plate 13 and screw steel plate 12 successively.
As shown in Figure 4, when oppressive fault and car heavy duty occur and make the action of cage side safety tongs in machine-roomless lift, two folder rope assemblies 1 of the present invention are clamped in respectively high-order on the cage side traction steel-cable 41 of traction sheave 3 both sides and to the low level on the heavy side traction steel-cable 42, then the hook 21 with chain block 2 hooks the hanging hole that clamps the folder rope assembly of heavy side traction steel-cable 42, lower suspension hook 22 is hooked the hanging hole of the folder rope assembly that clamps cage side traction steel-cable 41, again the operation chain 23 of chain block 2 is guided to outside the Room, cooperate the electromagnetic releasing band-type brake, operating operation chain 23, making hoisting chain 24 pulling cage side folder rope assemblies move down and heavy side is pressed from both sides the rope assembly moves up, thereby the traction traction steel-cable promotes car to flat bed toward the counterweight side shifting.
As shown in Figure 5, make when the heavy side safety tongs moved when oppressive fault and car underloading occur machine-roomless lift, two folder rope assemblies 1 of the present invention are clamped in respectively on the cage side traction steel-cable 41 of traction sheave 3 both sides low level and to the high position on the heavy side traction steel-cable 42, then the hook 21 with chain block 2 hooks the hanging hole that clamps the folder rope assembly of heavy side traction steel-cable 42, lower suspension hook 22 is hooked the hanging hole of the folder rope assembly that clamps cage side traction steel-cable 41, again the operation chain 23 of chain block 2 is guided to outside the Room, cooperate the electromagnetic releasing band-type brake, operating operation chain 23, making hoisting chain 24 pulling cage side folder rope assemblies move up and heavy side is pressed from both sides the rope assembly moves down, thereby the traction traction steel-cable moves toward cage side, reduces car to flat bed.
The present invention is not limited to above-mentioned embodiment, if various changes of the present invention or distortion are not broken away from the spirit and scope of the present invention, if these changes and distortion belong within claim of the present invention and the equivalent technologies scope, then the present invention also is intended to comprise these changes and distortion.
