Cross-shaped hoisting device for weight on table board of horizontal type test bed

Abstract

The invention provides a cross-shaped hoisting device for a weight on the table board of a horizontal type test bed, and belongs to the technical field of engineering carrying machinery. The problems in the conventional hoisting mode are that the requirement on environment is high, and the cost on environmental reconstruction and purchase of related equipment is high, that is, a travelling rail needs to be designed on the wall, a bridge crane needs to be purchased, electric transformation needs to be carried out and the like when the wall is subjected to high-strength high-rigidity design to prevent the damage on the wall. A longitudinal travelling device provided by the invention is provided with two travelling rails with safety catches along the beam length direction, a splayed bracket with a travelling wheel is arranged on the two travelling rails respectively, the tops of the two splayed brackets are fixedly connected with two ends of a horizontal travelling rail which spans over and is vertical to the longitudinal travelling device and is provided with a horizontal travelling device, and a chain block is arranged on the horizontal travelling device. The cross-shaped hoisting device is mainly used for vertically hoisting the weight on the surface of a tunnel-lining model test research table board.

Description

technical field [0001] The invention belongs to the technical field of engineering transport machinery, in particular to the vertical lifting and horizontal movement of heavy objects on the table for tunnel lining model test research. Background technique [0002] The existing horizontal tunnel lining model test bench has several tons of reaction force cover plates, several hydraulic cylinders over 100kg and other test supporting equipment above the bearing table. An overhead crane removes the above table weight. [0003] Existing mobile methods use bridge cranes, walking rails, hydraulic rollover drive mechanisms, etc. The walls on both sides of the experimental hall are equipped with bridge crane running rails and supporting electrical equipment, etc., and bridge cranes are placed on the running rails. The vertical column of the horizontal test bench adopts a rotating type. When it is necessary to move the reaction force cover plate and other related heavy objects of the...

AI Technical Summary

Problems solved by technology

[0004] The problem of adopting the existing hoisting method is that the requirements for the environment are relatively high, and the cost of environmental transformation and purchase of related equipment is relatively high. For example, the wall must be designed with high strength and high rigidity to prevent damage to the wall. The purchase of bridge cranes requires power transformation, etc.; the environmental adaptability is not strong, and if this type of test is to be carried out in a space where bridge cranes are not available, the existing scheme cannot be used; when lifting, the hydraulic control mechanism must be activated Rotate the column to the horizontal position, so that the reaction cover and other countertop weights are completely placed in the accessible area of ​​the bridge crane, and cannot be operated without power
