Product Detail

According to the law of fluid transmission, the hydraulic equipment of the spreader loading test is designed and developed by using the principle of servo control to simulate the loading system of acceleration process when the object falls.

The hydraulic equipment of the spreader loading test is to use the hydraulic characteristics to realize the control of the displacement and force of the cylinder through the automatic control of displacement closed-loop and force closed-loop. When testing different spreaders, as long as the corresponding model code is entered in the computer, the system will automatically prompt the servo system to control the action of the cylinder according to the model code, so as to realize the acceleration (braking force acceleration) when the object falls, and the change of loading force in the process of force sensor acquisition and then generate a map.

Features of hydraulic equipment for spreader loading test:

The equipment is divided into three parts: hydraulic system, frame structure and electronic control.

Hydraulics:

Operation: wire control handle, wireless handle;
Mode of transportation: manpower pushing, lifting, shoveling;
It is specially designed for the precision adjustment and positioning of small ship segments;
Two-speed electric pump, high efficiency when no-load adjustment, high precision when heavy load adjustment;
Optimized structural design, the equipment has a rated load capacity and a very large load capacity-to-weight ratio;
The large wheel diameter design makes it easy for the equipment to move forward and rotate by manpower, which is convenient for the equipment to be used in place under segmentation.

Frame structure part:

The design and manufacture of frame structure is designed in accordance with national and relevant industry standards;
The safety factor of spreader loading equipment is > 2, and the safety factor of key components is > 3;
Through the transfer bearing, different forms of spreader can be connected with the flexible platform;
A heavy-duty walking wheel device is adopted between the column and the platform, and the column frame is moved longitudinally through a motor;
The beam part is moved up and down along the column (2) by means of an electric hoist, and a locking device is installed on the beam. It can be locked in the appropriate position by locking the cylinder;
In order to ensure the damage of heavy objects to the character, each sports device is equipped with a sports safety device, and the moving parts cannot be moved before the safety is released.

Hydraulics:

The control adopts computer plus programmable automation motion controller PAC plus expansion module (analog signal input module, strain signal input module, analog signal output module, switching module), and the host computer is controlled in real time through Ethernet communication;
Parameters can be selected and set through the operation interface;
High-precision servo valves, which are suitable for position, speed, force (or pressure) servo control systems, and have high dynamic response;
Adopt dry torque motor and two-stage hydraulic amplifier structure;
The pre-stage is a double-nozzle baffle valve with frictionless pair;
The spool has a large driving force;
High dynamic response performance;
High resolution, low hysteresis.
