Abstract
The utility model relates to the underground construction machinery, in particular to diaphragm wall excavating equipment. A diaphragm wall grab bucket with double hoists comprises a tracked chassis of a control room, wherein a mast system is arranged on the tracked chassis; the top part of the mast system is provided with a crown block mechanism; power lifting mechanisms are also arranged on the tracked chassis and then are connected with a working mechanism after passing through the crown block mechanism by a steel cable; the power lifting mechanisms are two hoists with balance control systems; and the two hoists are arranged on the chassis. For the grab bucket, the working mechanism is stressed evenly, therefore, the working is stable; moreover, the working mechanism can realize the swing action, and the working is reliable.
Description
Technical field
The utility model relates to underground construction machinery, specifically, relates to a kind of continuous concrete wall excavating equipment.
Background technology
Underground continuous wall construction technique extensively adopts in modern capital construction construction, this kind equipment is normally having installation mast system on the crawler body of control cabin, mast system top is provided with a day mechanism of car, also be provided with power-lifter on the crawler body, and connect an operating mechanism after utilizing steel rope by the sky mechanism of car and increase hoisting capacity by the pulley mechanism that doubly restricts; The pulley mechanism structure complexity of doubly restricting, the manufacturing cost height; And winch of the general employing of so-called power-lifter, this kind equipment has problems such as cost height, poor reliability in application process.
For addressing the above problem, people consider to adopt the double hoisting machine.Yet owing to adopt the double hoisting machine, two strand steel wire ropes will inevitably run into the problem of tension imbalance, thereby cause operating mechanism to be rocked, and influence construction safety.
Summary of the invention
The utility model is intended to solve the described defective of prior art, and a kind of continuous concrete wall grab bucket with the double hoisting machine is provided.Grab bucket of the present utility model operating mechanism stress equalization, and can realize wobbling action, working stability is reliable.
The utility model is achieved in that a kind of continuous concrete wall grab bucket with the double hoisting machine, it includes the crawler body of control cabin, the mast system is installed on it, mast system top is provided with a day mechanism of car, also be provided with power-lifter on the crawler body, and utilize steel rope to pass through to connect an operating mechanism behind day mechanism of car, it is characterized in that, described power-lifter is two winchs that have balance control system, and these two winchs are arranged on the chassis.
The continuous concrete wall grab bucket of described band double hoisting machine, described balance control system is a hydraulic control system.
The continuous concrete wall grab bucket of described band double hoisting machine, described hydraulic control system comprises:
One cover feed apparatus, it comprises oil resevoir and two Hydraulic Pumps and hydraulic oil circuit, and one of them Hydraulic Pump is the active force pump, and another is auxilliary kinetic pump;
Two reducing valves, they are parallel to described active force pump discharge, and the winch of connecting respectively;
A change-over valve, it is series at auxilliary kinetic pump outlet, and its outlet is respectively by plumbing connection to two winch of hydraulic oil circuit;
A switch change-over valve, after it and described two reducing valves were parallel to the active force pump jointly, its outlet connected two winchs respectively;
An electrical controller, it comprises a controller, an actuating unit and two sensors, and these two sensors are separately positioned near the steel rope of two winchs, and described actuating unit then is positioned at switch change-over valve place and controls its unlatching or close.
Two winchs of the utility model have been installed pulling force sensor, measure the pulling force of winch respectively in real time, and signal is sent to controller, controller according to the input signal compare, if the difference that two signals take place greater than allowed band, controller will be to the reducing valve signal, change its pressure output, the discharge capacity of winch motor is with regard to corresponding change, and pull of steel wire is also along with change, up to their pulling force difference in allowed band.When controller detected two winch pulling force sums less than preset value, controller will be to the change-over valve give a signal, and the pressure oil of pump will drive winch and promote, and arrived preset value up to lineoutofservice signal pull.
