Problems solved by technology

The safety freight elevator provided by the utility model can control the opening and closing state of the car door and the rising and falling state of the car through the first sensing mechanism and the second sensing mechanism, without the need for staff to follow the freight elevator up and down and in and out, improving the The safety performance of the safety freight elevator saves labor costs. However, the freight elevator has no track lifting mechanism, and the goods can only be transported on the same level, which greatly limits the application of the freight elevator

Embodiment 1

[0037] A freight elevator, comprising a car 1, an electrical control device (not shown), a first driving device 2, a second driving device 3, a vertical telescopic shelf 4, and a vertical guide rail 5, wherein the first driving device 2 and the second driving device The second driving device 3 is connected with the electric control device and installed on the top inner wall of the car 1, the vertical guide rail 5 is installed on the surrounding inner wall of the car 1, and the vertical telescopic shelf 4 is a multi-layer structure, which includes a top plate 41, a cross movable Rod 42 , several intermediate transmission boards 43 and bottom transmission board 44 , the top board 41 is connected with the first driving device 2 , and the bottom transmission board 44 is slidably connected to the vertical guide rail 5 and connected with the second driving device 3 .

[0038] The cross movable rod 42 is used for the connection between the adjacent two layers in the vertical telescopi...

Embodiment 2

[0046] The steps of loading and unloading goods by using the above freight elevator are as follows:

[0047] Step 1. On the starting floor, according to the position of the input board outside the car and the height of the goods, the first drive device and the second drive device are controlled by the electric control device to lower the bottom transmission plate and the top plate, and the bottom transmission plate is lowered. The stroke is greater than the top plate, so as to stretch the vertical telescopic shelf until the distance between each layer of the vertical telescopic shelf is greater than the height of the goods, and the bottom transmission plate is flush with the input plate outside the car, and the pneumatic brake in the sliding groove of the bottom transmission plate is activated to connect the cross The movable rod and the pivot pin of the bottom transmission plate are fixed in the sliding groove, and then the goods are transported from the input plate outside th...

Abstract

The invention discloses a freight elevator, which includes a car, an electric control device, a first drive device, a second drive device, a vertical telescopic shelf, and a vertical guide rail. The control device is connected and installed on the top inner wall of the car, the vertical guide rail is installed on the surrounding inner wall of the car, and the vertical telescopic shelf is a multi-layer structure, which includes a top plate, cross movable rods, several middle layer transmission boards and bottom transmission boards , the top plate is connected with the first driving device, and the bottom transmission board is slidably connected with the vertical guide rail and connected with the second driving device. Through the cooperation of the first driving device and the second driving device, the freight elevator enables the vertical telescopic shelf to realize overall lifting while adjusting the distance between layers, improves the efficiency of cargo transportation, and solves the problem of long and difficult conveyor lines in the traditional freight elevator transportation system. The problem of high space usage.

Description

【Technical field】 [0001] The invention relates to the field of elevators, in particular to a cargo elevator and a cargo loading and unloading method thereof. 【Background technique】 [0002] Elevators are vertical lifting devices commonly used in modern buildings. The types mainly include passenger elevators, sightseeing elevators, cargo elevators, etc. Freight elevators are mainly designed for transporting goods. They are long and narrow. Box-like car with a car running between at least two vertical columns of rigid rails. [0003] In the prior art, the freight elevator is long and narrow, and workers usually enter the elevator with the goods. One is to reserve space for the workers to carry the goods to reduce the cargo capacity of the freight elevator, and the other is to waste labor costs and pose a safety hazard. [0004] The invention patent application with the publication number CN108217122A discloses a fully automatic transfer machine for freight elevator logistics,...
