Problems solved by technology

[0002] In the prior art, guardrail trolleys are generally only mechanized. For example, a Chinese invention patent with application number CN201810339504.4 discloses a combined mechanical trolley device for concrete construction of tunnel side ditches and bridge guardrails. Adaptation to the disassembly and assembly of the formwork, but due to the excessive use of flexible structures, construction personnel are required to operate on site and set up personnel standing positions for this purpose. The entire guardrail construction process cannot be automated, and the overall construction efficiency is low.
[0003] In order to solve the above problems, the applicant has designed an automatic guardrail trolley (a patent has been applied for separately), but correspondingly, since the technical solutions in the prior art cannot realize the whole process of electronic control operation, there is no such thing in the prior art Corresponding remote control or automatic control scheme

Embodiment 1

[0051] Using the above scheme, applied to figure 2 In the guardrail trolley complete control system shown, the telescopic component is an electromagnetic telescopic rod assembly, and the telescopic mechanism is an electromagnetic telescopic rod. The system is equipped with a video monitoring system, and the system is controlled through control buttons.

[0052] This embodiment is a relatively typical semi-automatic implementation of the present invention. The control method provided by the present invention is used as a system standard step, which is carried out under the remote adjustment of the operator. During the execution of each step, wait for the confirmation of the operator before continuing. In the follow-up process, the operator determines the actual operation of the system through the monitoring system.

Embodiment 2

[0054] Using the above scheme, applied to image 3 In the complete control system of the guardrail trolley shown, the telescopic component is a hydraulic system, and the telescopic mechanism is a hydraulic cylinder. The system provides control interaction through the HMI (Human-Machine Interface). This embodiment is a relatively typical automatic implementation of the present invention. Since the hydraulic system has its own feedback function, the position data of each hydraulic cylinder can be obtained without additional sensors, so that the position data of the hydraulic cylinder can be analyzed as The attitude information of the formwork system can realize the full automation of the whole process without operator participation. The attitude information of the formwork system can be recorded as historical data after being displayed on the HMI, which is convenient for subsequent playback and troubleshooting.

[0055] It can be seen from the above that based on the semi-automa...

Abstract

The invention provides a guardrail trolley integral control method, which belongs to a method special for erecting or assembling a bridge, and comprises the following steps of: advancing: controlling an advancing system to enable a template system to reach a preset position; formwork erecting, specifically, operating a telescopic mechanism in the telescopic assembly by controlling the telescopic assembly, so that the formwork system becomes a preset shape; pouring: starting a pouring system or sending a pouring signal; and vibrating: starting a vibrator. The guardrail trolley can be controlled without on-site operation, so that the labor cost is greatly reduced, the risk of on-site operation of personnel is reduced, debugging in a semi-automatic mode is facilitated, batch construction in an automatic mode is realized, and the overall construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to a control method and system for guardrail trolley assembly, which belongs to the method or equipment specially used for erecting or assembling bridges.
