Problems solved by technology

[0003] Due to the large number of parts and complex operation of the giant movable openable roof, it is very easy to make mistakes during the opening and closing process, which causes inconvenience in use. Repeated and multiple debugging to ensure the accuracy of opening and closing
However, in the existing practice, there are problems such as the multi-point driving super-static caused by the spherical roof, and the difficulty in matching the movable roof and the fixed roof caused by the deflection and deformation of the steel structure, which brings great difficulties to the debugging and use of the movable open roof. certain inconvenience

Embodiment Construction

[0048] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0049] to combine figure 1 and image 3 , taking Nantong Stadium as an example, the power drive and control equipment synchronous drive debugging method for the opening and closing roof system of the present invention includes the following steps:

[0050] Step 1: Preparation for commissioning and operation. In this project, the movable roof is synchronously driven by the multi-point hydraulic motor of the hoist. Before issuing the operation command, the pre-operation inspection should be carried out according to the hoist 4 and the inspection report of each arch day. Four sets of single-rate hoist 4 are used. The system drives a 1137-ton single-piece spherical roof 2. The two movable spherical roofs 2 are driven synchronously by 8 sets of hoisting systems, and each set of hoisting machines 4 uses 6 hydraulic motors + 1 reducer + 1 large...

Abstract

The invention discloses a retractable roof power driving and control device synchronous driving and debugging method. The retractable roof power driving and control device synchronous driving and debugging method can help obtain the technical parameters of off tracking of control trolleys in a multi-point hydraulic driving mode including hydraulic power systems, hydraulic rotating devices, hydraulic rotating device tail end large gear rings and a winch roller, guarantee the security and the quality and reduces the cost to a large extent. The retractable roof power driving and control device synchronous driving and debugging method solves the problem that a transmission structure is poor in integrality and low in reliability and two reducers cannot guarantee normal working of other equipment when breaking down. A driving system is composed of two sets of hydraulic power systems, and the hydraulic power systems supply power for the six hydraulic rotating devices, which are arranged on both sides of a winch and composed of low-speed large-torque hydraulic motors, brakes and planetary reducers, and six pinions provide transmission for the two tail end large gear rings on the both sides to drive the roller to rotate.

Description

technical field [0001] The invention relates to a motor drive debugging method, in particular to a synchronous drive debugging method for power drive and control equipment of an opening and closing roof system. Background technique [0002] Large-scale stadiums, especially some international large-scale stadiums, usually use giant movable open roofs. For example, Nantong Stadium is currently the first stadium in China to adopt giant movable open roofs. The maximum horizontal dimension is 262.458m, and the maximum vertical dimension is 265.460m, the middle distance of the main arch truss is about 40m, the middle distance between the main arch and the secondary arch truss is about 20m, and the steel structure consumption of the entire roof is 11000T. [0003] Due to the large number of parts and complex operation of the giant movable openable roof, it is very easy to make mistakes during the opening and closing process, which causes inconvenience in use. Carry out repeated an...
