Embodiment 1

[0024] Such as Figure 1-3 As shown, the present invention is a kind of safety lifting goods elevator system, comprises lifting stand 1, car 2, winch 3 and car stable pulley system 4, and described lifting stand 1 adopts gantry structure, in order to increase lifting stand To improve the stability of frame 1, a fixed support is added to the lifting stand 1 on site according to the actual situation. The hoist 3 is arranged on the top of the lifting stand 1 and drives the car 2 to lift through the lifting cable 5; the stable pulley system of the car 4 includes four pairs of pulley blocks 6, a stable support 7, four stable steel cables 8 and fixed pulleys 23, the stable support 7 is a square frame structure, and the stable support 7 is arranged on the crossbeam frame 9 below the lifting stand 1 and The car 2 corresponds up and down, the four pairs of pulley blocks 6 are respectively arranged on four diagonal corners of the stable support 7, and one end of the four stable steel ca...

Embodiment 2

[0026] Such as figure 1 As shown, the present invention is a safe lifting freight elevator system. On the basis of Embodiment 1, the freight elevator device is provided with a counterweight system 10 for controlling the smooth lifting of the car, and the counterweight system 10 includes Counterweight block 11, counterweight suspension rope 12, counterweight pulley 13 and configuration support 14, described configuration support 14 is arranged on the beam frame 9 side of lifting stand 1, and two described counterweight pulleys 13 are arranged on respectively On the corresponding beam frame 9 on the outside of the support 14 and the top of the car 2, one end of the counterweight sling 12 is connected to the car 2, and the other end of the counterweight sling 12 passes through two counterweight pulleys 13 and Counterweight 11 is connected. The ground corresponding to the counterweight 11 is provided with a safety fence 15 to play a role in safety. Lifting stand 1 top is provide...

Embodiment 3

[0029] Such as Figure 1-2 As shown, the present invention is a kind of safety lift freight elevator system, on the basis of embodiment 1, the both sides of described lift stand 1 are I-shaped steel columns 17, on both sides of described car 2 and I-shaped Two sets of guide roller sets 18 are respectively arranged at the corresponding positions of the steel columns 17, and the described guide roller sets 18 include three guide rollers 19, and the three guide rollers 19 are respectively arranged on both sides and inner surfaces of the I-shaped steel columns 17. scroll. The four sets of guide roller groups 18 provided on both sides of the car 2 can make the car 2 lift up and down along the I-beam column 17 to prevent the car from deviating.

Abstract

The invention discloses a freight elevator system capable of safely lifting up and dropping down. The freight elevator system comprises a lifting vertical frame, a lift car, a winding engine and a lift car stabilizing pulley system; a portal frame structure is adopted by the lifting vertical frame, and the winding engine is arranged on the top of the lifting vertical frame and drives the lift car to lift up and drop down through lifting steel cables; the lift car stabilizing pulley system comprises four pairs of pulley sets, a stabilizing support, four stabilizing steel cables and a fixed pulley, the stabilizing support is of a square frame structure, the stabilizing support is arranged below a beam frame of the lifting vertical frame, the stabilizing support and the lift car correspond to each other in an up-and-down mode, the four pairs of the pulley sets are arranged on the four opposite angles of the stabilizing support respectively, one ends of the four stabilizing steel cables are fixedly connected to the four corners of the lift car respectively, the other ends of the stabilizing steel cables extend upwards to horizontally penetrate through the two pairs of the pulley sets on the stabilizing support and then penetrate through the fixed pulley fixed to the ground to be connected with the bottom of the lift car, and a lift car stabilizing pulley system is arranged on a freight elevator device.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a safe elevator system for lifting goods. Background technique [0002] Elevators are common carrying equipment in people's daily lives. Elevators are generally installed in residential buildings, commercial buildings, office buildings, stations, shopping malls, subways and other places with ups and downs. Elevators are divided into manned elevators and freight elevator. In terms of structure, elevators can be divided into closed type, walking type and so on. The closed type is generally also called the well type. Generally, escalators are suitable for short-distance transportation in public buildings, and enclosed elevators are widely used, but automatic leveling, automatic speed control, automatic door opening and closing, etc. have high technical requirements, and their control systems are also very complicated. , so the price is generally higher, the failure rate is higher, the ma...
