Concrete pumping equipment and arm support state control system thereof

Abstract

The invention discloses an arm support state control system, which comprises a detection device (1), a storage device (2), a control device (3) and an actuating device (4), wherein the detection device (1) is used for detecting the position state and vibration state of an arm support (8) of concrete pumping equipment to obtain a position state signal and a vibration signal; the storage device (2) is used for storing the vibration signal to obtain the periodical vibration signal of the arm support (8); the control device (3) is used for receiving the position state signal, the vibration signal and the periodical vibration signal and obtaining a control instruction according to a preset arm support vibration range, a preset advanced regulation time and a preset control policy; and the actuating device (4) is used for changing the state according to the control instruction and controlling the arm support (8) to act the preset arm support vibration range. The arm support state control system provided by the invention can avoid control error caused by time delay in the detection process of the detection device and the actuating process of the actuating device, absorb vibration in time and improve the operation convenience of the arm support. The invention also discloses concrete pumping equipment.

Description

technical field [0001] The invention relates to the field of concrete pumping equipment, in particular to a boom state control system. The present invention also relates to a concrete pumping equipment comprising the above-mentioned boom state control system and a boom state control method. Background technique [0002] With the rapid development of the national economy and urban construction, concrete pumping equipment, as the main construction machinery in the construction process, plays an increasingly important role. [0003] In order to accurately pump the concrete to the target position, a boom is generally installed on the concrete pumping equipment. In the prior art, there are two main types of settings for the boom: one is to install the boom and the concrete delivery pump together On the truck chassis, which is commonly referred to as a concrete pump truck; the other is to install the placing boom on the lifting table, crane or the wall column of the building. ...

Problems solved by technology

[0005] Since the pumping method of the concrete delivery pump is a double-piston feeding cylinder, there is a reversing time during the working process, so that the concrete delivery is not carried out continuously, but in a pulsed manner, which is inevitable. The ground will produce material supply impact. Under the action of pulsating impact, the boom of the placing boom will vibrate, especially when the conveying volume of concrete is large or the frequency of pulsating impact is close to the natural frequency of the boom. It will be more violent, and the vibration amplitude will also increase significantly, which not only makes it difficult to control the position of the discharge port of the conveying pipeline, but also causes cracking of the boom, and even causes personal injury to the construction personnel; in order to prevent the above In the actual operation process, the staff had to reduce the pumping volume of the concrete delivery pump, however, this would affect the construction efficiency
