Problems solved by technology

At present, cranes such as cranes or cranes are often used for hoisting operations, but changing the placement state of large cement prefabricated parts by crane hoisting is inefficient and difficult to operate; and after hoisting, it will be limited by the space of the site, and it is impossible to carry out short distances quickly. Transition; in addition, the position of the center of gravity during operations such as large-scale component overturning is uncontrollable, and there are safety risks such as deflection, irregular shaking, and sudden impact

Embodiment 1

[0039] as Figure 1 As shown: forklift hydraulic system for large member flipping, comprising an electronic control handle 10, and a rotating mechanism mounted on the forklift attachment, a horizontally moving cylinder 6 and a pressing cylinder 14, the compression cylinder 14, the rotating mechanism are successively connected by the integrated valve block 16, the main multi-way valve 2 and the hydraulic tank 1 are connected to form their respective hydraulic circuits, respectively, so that the large components clamp and rotate; The main multi-way valve 2 and the horizontal moving cylinder 8 are connected to form a hydraulic circuit so that the large member is centered on the forklift attachment; The signal end of the electronic control handle 10 is electrically connected with the integrated valve block 16, the main multi-way valve 2.

[0040] Further, the rotating mechanism is a hydraulic rotating motor 13, the horizontal moving cylinder 8 of the cylinder body is fixed mounted on t...

Embodiment 2

[0071] Hydraulic control method of forklift for flipping large preform parts, which comprises the following steps:

[0072] Step 1: The pressure signal end of the main valve plate in the main multi-way valve 2 is connected with the signal end of the variable pump 7, and the pressure signal of the main valve plate is fed back to the variable pump at any time, so as to control the speed of the variable pump and the output flow of the hydraulic oil; Among them, the main pressure of the system is 225 bar during operation, the variable pump speed is controlled between 1800-1910r / min, and the output flow of hydraulic oil is accurately controlled at 46±3L / min;

[0073] Step 2: the large prefab is placed on the fork rack, the clamp button on the electronic control handle 10 is manipulated, one of the main valve plates in the main multi-way valve 2 works, the hydraulic oil is fed into the integrated valve block 16; At the same time, the spool of the second three-position four-way solenoid ...

Abstract

The forklift hydraulic system comprises an electric control handle, a rotating mechanism, a horizontal moving oil cylinder and a pressing oil cylinder, the rotating mechanism, the horizontal moving oil cylinder and the pressing oil cylinder are installed on an attachment of a forklift, and the pressing oil cylinder and the rotating mechanism are sequentially connected through an integrated valve block, a main multi-way valve and a hydraulic oil tank to form respective hydraulic loops. Clamping and rotating the large component respectively; the main multi-way valve and the horizontal moving oil cylinder are connected to form a hydraulic loop so that the large component can be centered on the forklift attachment. The signal end of the electric control handle is electrically connected with the integrated valve block and the main multi-way valve. According to the invention, the forklift is adopted to transfer the large components, and the centering, pressing and overturning operations and the rapid short-distance transition of the large components are realized. And it is guaranteed that the center-of-gravity position of the large component is kept in the center in the operation process of overturning and the like, and safety risks such as deflection, irregular shaking and sudden impact are avoided.

Description

Technical field [0001] The present invention relates to the technical field of handling tools vehicles, specifically to a forklift hydraulic system for flipping large components and control methods. Background [0002] Concrete precast parts refers to the production of concrete products through standardized and mechanized processing in the factory, with the continuous development of the construction industry, various concrete precast parts have been widely used in various buildings, playing an important role in the national economy. For example, the tunnel construction site requires a large number of large cement prefabs for construction, and different sites need to be transferred between them, such as the need to move cement preforms from the horizontal state to the vertical state to facilitate transportation, installation, loading and unloading and other simple operation positions. At present, cranes such as cranes or cranes are mostly used for lifting operations, but the place...
