Description

This is a machine; Figure 2 is a block diagram of a device for implementing the method.

It contains serially connected first directional control valve 1 and side slope hydraulic cylinder 2, serially connected second directional control valve 3 and rear brace hydraulic cylinder 4, sensors of longitudinal 5 and lateral slopes, limiters of lateral transverse 7 and longitudinal 8 mast deviation angles with the pile relative to the pile driving machine, adjusters of the maximum permissible deviations in the transverse 9 and longitudinal 10 planes x of the piling machine relative to the gravitational vertical, adjusters of the maximum allowable the mast deflection relative to a given position in the transverse 11 and longitudinal 12 planes, mode switch 13, software and computing unit 14, indicator 15, first 16 and second 17 limit switches.

A method for monitoring the operating position of a mast with a pile is as follows.

Before the piles are immersed in the ground, the mast is deflected in the longitudinal and lateral directions to the limiting angles given by the construction of the machine yo and Vo, the pitch angles of the SPM and the roll angle between the mast and the gravitational vertical, which are sums, are measured;

An apparatus for implementing this method operates as follows. Before starting the switch

13 modes include a mode for setting the initial conditions, in which, with a limiter of transverse 7 and longitudinal 8, the mast deflection angles from its relatively piling machine, the maximum permissible deviations in the transverse 9 and 10 longitudinal planes of the piling machine relative to the gravitational vertical, Masts of maximum permissible deviations of the mast relative to a given position in the transverse 11 and longitudinal 12 planes are entered into the memory of the software

14 values of V0, V0, VMaui, Umash. Umachty, Umachty. During the task, they are displayed on the indicator.

Next, the mode switch 13 is included in the preparation mode of the exhibition piling machine. Hydroallocators 1 and 8, the operator controls the lateral brace 2 and rear brace 4 cylinders to the stop, in connection with which limit switches 16 and 17 are closed, the electrical signals from which through the computing and computing unit 14 display the NORMAL symbol on indicator 15.

Then, the mode switch 13 is turned on to the piling machine exhibition mode, in which longitudinal UISM and transverse Wismugles of mast inclination relative to the gravitational vertical are measured with sensors 5 and 6. In block 14 in this mode, the transverse and longitudinal ANGLES Umash and Umash are calculated using formulas (1)

by UIMM signals UISM received from the first and second inputs of block 14 and у0, V0 from the memory of block 14.

Values Umash. The mind is displayed on indicator 15. and the operator begins to expose the machine to the horizon, reducing these angles. In this mode, in block 14, the signals are constantly compared using formulas (2). And in case of proper exposure of the pile driving machine, the NORM symbol will be displayed on the indicator 15.

Next, the switch 13 modes include on the mast exhibition mode. In this mode, signals from transverse 5 and longitudinal slope sensors are induced on the indicator 15 through a software-computing unit 14, and also in block 15, the signals are compared using formulas (3). The operator through the control valves 1 and 3 and, accordingly, the hydraulic cylinders 2 and 4 sets the mast in accordance with the specified installation angles VyCT and set relative to the gravitational vertical.

 In the case of the correct installation of the mast, inequalities (3) are fulfilled, and the NORM symbol is displayed on the indicator, which means that the mast with the pile is ready for immersion in the ground.

This method of monitoring the working position of the mast with the pile and the device for its implementation will automate the process of exhibition and control the working position of the piling machine and mast with the pile, increase the productivity and accuracy of the exhibition of the piling machine and mast with the pile before immersion in the ground.
