Description
Technical Field
The invention relates to a shielding door, in particular to a door beam testing tool of the shielding door.
Background
The screen door system is a commonly used safety protection mechanism in industry, and is particularly widely applied to rail transit platforms.
The shielding door system comprises a door machine transmission system, a door body and a control system, and a door machine beam is a main part of the door machine transmission system. The shield door needs to be subjected to a rigorous reliability test in the research and development and production processes. The shield door system test mainly tests the operation condition of the shield door through a control system, a local control box LCB, a central control panel PSC and a local control panel PSL are used for carrying out signal transmission on a control system DCU, the action of a door machine transmission system is controlled by the DCU, and the door machine transmission system drives a door body to operate. The door body should be normal, the unusual sound of free from, and the door body can open automatically when meetting the barrier more than 5mm thick at the in-process of closing the door, and self-closing again after 3 seconds of static, if the barrier still exists, the shield door will report to the police, and the door body is in the open mode forever, until the troubleshooting.
When a first model machine of the shielding door is used for type tests, millions of door opening and closing tests are required to verify whether opening and closing of a door body are normal or not and whether the structure and the electric part of the door body are correct or not. Each door machine beam needs 1000 times door opening and closing tests in the delivery process, and the tests cannot be performed on a platform, so the test needs to be performed by simulating the environment and the door body structure of the subway platform. The portal crane beam test board is a test system manufactured by simulating the portal crane running environment on site, and is matched with a portal crane bearing tool to simulate the portal crane body of a platform, so that the whole test can be completed. Specifically, on the crossbeam of door machine roof beam erection test platform, will simulate the door body hoist and mount on the door machine roof beam, the bottom of the door body is equipped with the guide vane, and the guide vane adaptation is in the direction recess of testboard bottom, then tests the operational aspect that the door machine roof beam drove the door body through control system.
When the door machine beam tests, a product is tested at every time, after the door machine beam is disassembled, the door bearing tool is separated from the fixation of the door machine beam, no fixed supporting point position exists on the test board, the door bearing tool is shaken all around and is easy to topple, the door bearing tool needs to be taken down, the door bearing tool is installed again after another door machine beam is replaced, and then the next door machine beam can be installed for testing. It takes a long time to reinstall the door load-bearing fixture each time.
The existing door machine beam needs to be disassembled and reassembled with a door bearing tool in the testing and debugging process, and has the following defects:
1) two bearing doors and 8 piece bearing blocks are 160 KG's weight altogether when door machine roof beam is dismantled, need two artifical people to assist, on the frock car of putting the testboard next door is taken off to one, this process personnel fatigue degree is very big, and does not have haulage equipment such as driving a vehicle in handling, and the too heavy numerous transport of bearing block causes personnel's incident easily, and the manpower consumes highly moreover.
2) The bearing block is moved on the tool car beside the test board, the test space is narrow, and 5S management is influenced.
3) The door bearing tool takes a long time to disassemble and reassemble, and needs about 40 minutes.
4) Because of trading a door machine roof beam at every turn, door bearing frock can not be fixed, need with a machine roof beam dismantle together and remount again, lead to remounting the position and the height all have the difference after the door bearing frock, the frictional force between door bearing frock and a machine roof beam testboard recess also has the difference, nevertheless the test requires this frictional force to be less than 67N, if the bearing door installation is good frictional force too big leads to the fact the door can not normally operate easily, then must carry out the bearing door again installation, debug again. The high requirements of friction also lead to repeated installation and repeated commissioning of the door load-bearing tooling, each commissioning of which takes about 15 minutes.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a time-saving and labor-saving testing tool for a door frame beam of a shielding door aiming at the current situation of the prior art.
