Abstract
The invention discloses a start and stop control device and control method of a self-travelling overhead working truck. The start and stop control device of the self-travelling overhead working truck comprises an electric control valve, a reversing valve and a hydraulic pump. The electric control valve is connected with the hydraulic pump through a hydraulic oil way. The hydraulic pump is connected with the reversing valve through a hydraulic oil way. The reversing valve is connected with the electric control valve through a hydraulic oil way. The start and stop control method of the self-travelling overhead working truck comprises the following steps that: flow-rate variation in the hydraulic system is controlled through the electric control valve; relatively changed accelerated speeds are generated and acted in a reverse motion direction; at the speed changing initial stage, the accelerated speed is higher; the speed is changed rapidly; the speed is lower; in the event of approaching to a target, the accelerated speed is reduced; the speed is changed slowly; and finally, the self-travelling overhead working truck stops at a lower speed. According to the device and the method disclosed by the invention, the stability of a work basket is improved; the service life of equipment is prolonged; and the equipment investment is reduced.
Description
Technical field
The present invention relates to a kind of self-propelled aerial working car start and stop control setup and control method.
Background technology
Aerial platform is meant more than 3 meters, by hydraulic pressure or many hydraulic rams of power driven system domination, and lifting a kind of vehicle of carrying out operation up and down.Its start and stop control setup generally adopts hydraulic driven, Hydraulic Pump, change-over valve are by the hydraulic circuit direct connection, can't do actv. control to speed during start and stop, the anxious situation that opens, suddenly stops appears easily, there is very big startup to impact to driving system itself, make that its service life is shorter, increased staff's danger coefficient, energy consumption is also bigger.
Summary of the invention
The purpose of this invention is to provide a kind of can effectively alleviating aerial platform and open/stop in the process, improve the self-propelled aerial working car start and stop control setup and the control method of work basket stationarity the impact of driving system and electrical motor.
The objective of the invention is to be achieved through the following technical solutions:
The present invention's self-propelled aerial working car start and stop control setup comprises electrically-controlled valve, change-over valve, Hydraulic Pump, described electrically-controlled valve is connected with Hydraulic Pump by hydraulic circuit, described Hydraulic Pump is connected with change-over valve by hydraulic circuit, and described change-over valve is connected with electrically-controlled valve by hydraulic circuit.
The present invention's self-propelled aerial working car start and stop control method is, by the flowrate variation in the electrically-controlled valve controlled hydraulic system, the acceleration/accel that produces respective change acts on the reversing sense of motion, and in the velocity variations starting stage, acceleration/accel is bigger, velocity variations is very fast, speed is less, and near target the time, acceleration/accel reduces, velocity variations is less, finally stops with less speed.Specifically, be that acceleration/accel is bigger in the velocity variations starting stage, velocity variations is very fast, and speed is less, and near target the time, acceleration/accel reduces, and velocity variations is less.For example, when the work basket rises, with bigger acceleration/accel, less speed starts, and along with speed constantly increases, acceleration/accel reduces gradually, finally at the uniform velocity rise, when the work basket is about to arrive the desired location, apply an acceleration/accel with the direction opposite with respect to speed, during beginning, speed is bigger, and acceleration/accel is bigger, it is very fast that speed reduces, and when arriving the reservation position, speed is less, acceleration/accel also diminishes, and velocity variations is less, finally stops with less speed.
The present invention can improve the stationarity of work basket, prolongs the service life of equipment, reduces equipment investment.
Description of drawings
Fig. 1 is a self-propelled aerial working car start and stop control setup example structure block diagram of the present invention;
Fig. 2 is a self-propelled aerial working car start and stop control method diagram of circuit of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to Fig. 1, self-propelled aerial working car start and stop control setup embodiment of the present invention comprises electrically-controlled valve 1, change-over valve 2, Hydraulic Pump 3, electrically-controlled valve 1 is connected with Hydraulic Pump 3 by hydraulic circuit, described hydraulic oil pump 3 is connected with change-over valve 2 by hydraulic circuit, and described change-over valve 2 is connected with electrically-controlled valve 1 by hydraulic circuit.
With reference to Fig. 2, self-propelled aerial working car start and stop control method of the present invention: step 21 is an initial step, and the self-propelled aerial working car is started working; Then execution in step 22 judges whether the handle instruction changes (instruction that the handle instruction is meant the adjustment aerial platform mode of operation that is sent by the handle control button); As being to deny, then execution in step 23, normal operation; As for being that then execution in step 24, calculate the difference of former dominant discharge and target flow; Then execution in step 25 was scaled flow change rate with this difference in 2 seconds that set; Execution in step 26 then, come dominant discharge to change with described flow change rate (acceleration/accel); Then execution in step 27 judges whether near target flow; As for being that then execution in step 28, reduce flow change rate (variable-acceleration); As being to deny, then execution in step 29, judge whether to realize the flow control expected value; As for being, then execution in step 30, finish slope control; As for not, then return execution in step 26, come dominant discharge to change with the flow change rate (acceleration/accel) that calculates previously, circulation is gone down according to this.
