Problems solved by technology

The disadvantage is that ground forklifts are inconvenient to operate when there are many ground equipment or narrow aisles, and automation is difficult to realize; when the material storage rack is high and exceeds the maximum lifting height of the forklift, it is not easy to use forklifts to carry materials
The steel wire rope is soft and cannot be controlled left and right. It is easy to turn and swing when transporting long strip materials such as steel bars. It is difficult to control when stacking. It is difficult to place steel bars or other goods accurately, and it is even more difficult to put them on shelves.
There are potential safety hazards when goods are controlled manually on site

Embodiment 1

[0037] Such as Figure 1 to Figure 5 As shown, a double-beam bridge portal type stacking crane includes a bridge portal frame, a cart, a trolley and a spreader. The cart is set on the guide rail of the bridge door frame and moves back and forth along the bridge door frame, the trolley is set on the cart, and moves back and forth along the cart, and the spreader is set on the cart. Such as Figure 4 As shown, the trolley is divided into an upper trolley 14 and a lower trolley 15. The upper trolley 14 is equipped with a hoisting mechanism and is connected to the fixed carriage 1 of the spreader through a flange 20; the lower trolley is equipped with a traveling mechanism and a rotary motor 18. The upper trolley 14 and the lower trolley 15 are connected by a slewing support (bearing), wherein the slewing support inner ring 17 is fixedly connected to the lower trolley 15, the slewing support outer ring 16 is fixedly connected to the upper trolley 14, and the slewing support outer r...

Embodiment 2

[0045] In the first embodiment, the track one 4 and the track two 5 are designed as guide grooves, the moving carriage 2 is connected to the track one 4 through rollers, and the forklift carriage 3 is also connected to the track two 5 through the rollers; or the track one 4 and the track two 5 One is a guide rail and the other is a guide groove. For the moving carriage 2 and the forklift carriage 3, the sliding blocks corresponding to the guide rails or the rollers corresponding to the guide grooves are connected to the rail one 4 and the rail two 5 respectively.

Embodiment 3

[0047] Such as Image 6 As shown, in order to ensure that the force of the wire rope 13 is even, a balance arm 12 is provided on the fixed pulley group 6, and the fixed pulley group 6 containing three fixed pulleys is replaced with a combination of a fixed pulley group 6 containing two fixed pulleys and a balance arm 12, and balance The arm 12 is connected to the movable pulley block 7 through a wire rope 13.

Abstract

The invention provides a double-beam gantry stacking crane, and belongs to the technical field of cranes. The double-beam gantry stacking crane comprises a gantry, a cart, a trolley and a lifting appliance, wherein the lifting appliance comprises a fixed sliding frame, a moving sliding frame and a forklift sliding frame which are sequentially connected; the fixed sliding frame is connected with the trolley through a flange; a track I is arranged on the fixed sliding frame; the moving sliding frame is arranged on the track I; a pulley block is arranged on the trolley and is connected with the moving sliding frame; the moving sliding frame moves up and down along the track on the fixed sliding frame under the action of the pulley block; a track II is arranged on the moving sliding frame; theforklift sliding frame is arranged on the track II and is connected with the fixed sliding frame through a soft rope; a pulley is arranged on the moving sliding frame; the soft rope bypasses the pulley; the forklift sliding frame moves up and down along the track II under the action of the soft rope; and a fork is arranged at the lower end of the forklift sliding frame. The double-beam gantry stacking crane can simultaneously replace the function of a forklift and the lifting function of an electromagnet lifting appliance when ground equipment is provided with a plurality of passages and is narrow, so that the number of material placing layers is larger, and the utilization rate of a warehouse is increased.

Description

Technical field [0001] The invention belongs to the technical field of cranes, and more specifically, relates to a double-beam bridge gantry stacking crane and an application workshop thereof. Background technique [0002] Bridge crane is a type of bridge portal crane that runs on elevated tracks, also known as overhead cranes. The bridge frame of the bridge crane runs longitudinally along the tracks laid on both sides of the elevated track, and the lifting trolley runs along the bridge laid on the bridge. The track runs horizontally to form a rectangular working range, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of cranes. However, the spreaders of bridge cranes generally use electromagnetic spreaders. After medium and small bars are lifted by electromagnet spreaders, residual magnetism will remain, which will damage the materials being transported. [0003] T...
