Problems solved by technology

[0003] When the existing elevator guide rail frame is unstable, there is no instrument on the elevator to detect the instability of the elevator guide rail frame, and it does not meet the requirements of the general rules for the cage in the dual-purpose construction elevator for people and goods that do not meet the vertical guidance of the cage. Can detect unstable guide rail frame sections, and can prevent the cage from entering the guide rail frame section or ensure that the cage does not leave the stable guide rail frame section" standard requirements

Embodiment 1

[0030] Such as figure 1 As shown, the safety cargo lifting mechanism of this embodiment includes a base frame 1, a first rail frame 2 and a second rail frame 3 that are parallel to each other, and the first rail frame 2 and the second rail frame are arranged on the base frame 1. The frames 3 are vertically fixed on the base frame 1. A transport box 4 is arranged between the first rail frame 2 and the second rail frame 3. The transport box 4 may be a box composed of a wooden frame, which is fastened by screws to facilitate ventilation during cargo transportation. Several spring buffers 41 are provided at the bottom of the transport box 4. The spring buffer is an energy-storing buffer. When the box is dropped in an emergency, the spring buffer is impacted, and the kinetic energy and potential energy of the box can be converted into spring elastic potential energy to ensure that the box lands on the ground as quickly as possible and avoid repeated rebounds. The damage caused.

Embodiment 2

[0036] Such as figure 2 As shown, in addition to the structure of embodiment 1, the safety cargo lifting mechanism of this embodiment also includes an emergency braking device 13, which includes a speed reducer 131 and a speed limiter 132 arranged at the bottom of the top frame. And the safety wire rope 133 connected to the upper end of the transport box 4, the speed reducer 131 and the speed limiter 132 are connected to the electric control device 7, and an alarm light 134 is also included, which is electrically connected to the speed reducer 131 and the speed limiter 132.

[0037] The speed reducer 131 can automatically reduce the acceleration when the transport box rises to the top end or drops to the bottom end, which is helpful for smooth operation; the speed limiter 132 monitors the moving speed of the box in real time. When an overspeed situation occurs, that is At 115% of the rated speed of the elevator, it can send out a signal in time, and then produce mechanical action...

Abstract

The invention discloses a safe goods lifting mechanism. The safe goods lifting mechanism comprises a bed frame, a first guide rail frame and a second guide rail frame, wherein the first guide rail frame and the second guide rail frame are arranged on the bed frame and are parallel. A conveying box is arranged between the first guide rail frame and the second guide rail frame. The upper ends of the first guide rail frame and the second guide rail frame are fixedly provided with a top frame. The upper end of the top frame is provided with a conveying mechanism. The guide rail frames are connected with an electrical control device. A laser emitter is arranged at the connection portion between the bottom ends of the guide rail frames and the bed frame. The lower end of the top frame is provided with a laser receiver matched with the laser emitter. The safe goods lifting mechanisms can guarantee that the goods are always kept stable in the conveying process and cannot incline, on the emergency conditions of power failure and drive motor failure, emergency brake is automatically conducted, the work efficiency of drive motors is improved, the extra consumption of electricity is reduced, the safety coefficient of the lifting mechanism is increased, and the service life of a safety mechanism is prolonged.

Description

Technical field [0001] The invention relates to the field of elevators, in particular to a safe cargo lifting mechanism. Background technique [0002] At present, the lifting mechanism is widely used in the fields of lifting, loading, transportation, etc. The common lifting mechanisms include cranes and elevators. The lifting mechanism is mainly composed of lifting motor, reducer, steel cable, winch and so on. Its basic working principle is to drive the winch to rotate forward and backward by controlling the rotation direction of the lifting motor, so as to realize the retracting and unwinding of the winch to the steel cable and complete the lifting of the lifting object. But for some more important occasions, such as the promotion of important equipment, more safety and reliability need to be considered. Once the lifting mechanism fails, on the one hand, more safety measures must be taken to prevent the goods from falling quickly and damaging the goods. ; On the other hand, it...
