Problems solved by technology

[0003] In the construction of high-rise buildings, elevators will be built for material transportation. This kind of elevator uses simple counterweights as counterweights during construction, and can keep the weight difference between shelves and counterweights within the limit during elevator work. It is an important part of the elevator lifting mechanism to ensure that the traction transmission of the elevator is normal. Freight elevators are frequently used during the construction phase, and the gravitational potential energy of the counterweight is wasted, resulting in a large power consumption of the elevator.

Embodiment 1

[0028] refer to Figure 1-3 , an elevator hoisting mechanism for energy saving and environmental protection, comprising two limit rails 8 arranged in parallel, a counterweight 5 is arranged between the two limit rails 8, and a mounting groove 10 is arranged in the middle of the counterweight 5, and the installation Both ends of the groove 10 are fixedly equipped with a connecting frame 14, and the inside of the two connecting frames 14 is slidably connected with a bolt rod 4, and the top of the bolt rod 4 is fixedly equipped with a lanyard part 9, and the outer top of the bolt rod 4 and the The bottom is hinged with a plurality of pull rods 17, and the movable frame 16 of L-shaped structure is hinged between the other end of the pull rod 17 and the end of the connecting frame 14, and the end of the movable frame 16 is hinged with a mounting frame 1, and the mounting frame 1 Both ends of the interior of the motor are fixedly installed with a micro-generator set 3, the end of th...

Embodiment 2

[0039] refer to Figure 1-5 , an elevator lifting mechanism for energy saving and environmental protection. Compared with Embodiment 1, in this embodiment, a plurality of elastic pads 20 are fixedly installed on both sides of the counterweight 5, and protective pads are fixedly installed between the ends of the elastic pads 20. Side plate 19, the side four jiaos of protection side plate 19 all offer bar-shaped hole, and the inside of bar-shaped hole is equipped with roller wheel 21 by bearing, and the side of roller wheel 21 contacts with spacing track 8 outsides.

[0040] When the present embodiment is in use, when the counterweight 5 moves between the two limit rails 8, the protective side plates 19 on both sides can monitor its movement track, and the counterweight 5 is limited to the limit track 8 In between, avoid shaking and offset when momentary force is applied, and improve stability during exercise.

Abstract

The invention discloses an energy-saving and environment-friendly elevator lifting mechanism, relates to the technical field of elevators and aims to solve the problem that the gravitational potentialenergy of a balancing weight is wasted as a freight elevator is frequently used in a construction stage. The energy-saving and environment-friendly elevator lifting mechanism specifically comprises two parallelly arranged limiting tracks, wherein the balancing weight is arranged between the two limiting tracks, a mounting groove is formed in the middle of the balancing weight, connecting racks are fixedly mounted at two ends of the mounting groove, and a tightening latch is slidably connected between the two connecting racks internally and a rope hanging part is fixedly mounted at the top endof the tightening latch. When a faulted storage rack is too high in descending speed, the displacement distance between the balancing weight and the tightening latch is increased as a result of inertia effect, and further, mounting racks on two sides are extruded by means of action of a pull rod, so that a friction piece is in contact with the surfaces of the limiting tracks and resistance is increased to further expand a push-pull effect of the pull rod to achieve a self-locking friction effect, and therefore, the descending speed of the elevator storage rack is further reduced, and the using safety of the storage rack elevator is improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an energy-saving and environment-friendly elevator lifting mechanism. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails perpendicular to the horizontal plane or with an inclination angle of less than 15° from the plumb line. The elevator is mainly composed of a traction machine ( Winch), guide rail, counterweight device, safety device (such as speed limiter, safety gear and buffer, etc.), signal control system, car and hall door, etc., the two ends of the traction rope are respectively connected to the car and counterweight , wound on the traction wheel and the guide wheel, the traction motor drives the traction wheel to rotate after the speed is changed by the reducer, and the traction force generated by the friction between the traction rope ...
