Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1 to 3, a coal mine main and auxiliary shaft elevator speed protection test system, the elevator includes track 1 and winch 2 that slides and sets up on track 1, the system includes a plurality of induction unit 3 that sets up on track 1 along length direction and the computer with all induction unit 3 communication connection, induction unit 3 is including setting up upper substrate 4 in track 1 side, wear to be equipped with a plurality of upper permanent magnet 5 that adsorbs on track 1 on upper substrate 4, and upper permanent magnet 5 and upper substrate 4 fixed connection, upper substrate 4 fixed connection has fixed plate 14 that extends dorsad, fixed plate 14 is last to be provided with second fixed block 15, fixed proximity switch 16 that is provided with on second fixed block 15, proximity switch 16 is towards the middle part of track 1.

The utility model discloses when using, at first according to the experimental actual demand of speed protection, select the induction element 3 of suitable quantity and install on corresponding position, during the installation, laminate upper substrate 4 at track 1's lateral part at first, it adsorbs together to go up permanent magnet 5 and track 1, because upper substrate 4 and 5 fixed connection of last permanent magnet, so can fix upper substrate 4 on track 1, need not to use the connection structure of needs extra operations such as bolt, it is more convenient to install, and when the position of induction element 3 is changed to needs, only need hard will go up permanent magnet 5 and track 1 separation can, can realize quick adjustment. After the sensing units 3 are installed and before the speed protection test is started, the proximity switch 16 is powered on, the proximity switch 16 is turned on, when the winch passes through the proximity switch 16, the position of the winch is sensed by the proximity switch 16, and the position of the winch can be calculated according to the distance between the two sensing units 3 and the driving time of the winch, so that the speed protection test is completed.

Further, the induction unit 3 comprises a lower substrate 10 arranged on the side of the track 1, the lower substrate 10 is fixedly connected with a lower permanent magnet 8, the lower permanent magnet 8 is adsorbed on the track 1, and a support rod 11 is connected between the lower permanent magnet 8 and a fixing plate 14. After the upper substrate 4 is fixed, the lower substrate 10 is moved to make the lower permanent magnet 8 be adsorbed on the rail 1, and the lower substrate 10 is matched with the support rod 11 to reinforce the fixing plate 14, so as to avoid the fixing plate 14 from shaking due to the vibration of the rail 1, and further influence the sensitivity of the proximity switch 16.

Further, the setting mode of the support rod 11 is as follows: a first fixing block 13 is fixedly arranged on the fixing plate 14, an upper pin shaft 12 is fixedly arranged on the first fixing block 13, a lower pin shaft 9 is fixedly arranged on the lower permanent magnet 8, and two ends of the supporting rod 11 are respectively in rotating connection with the upper pin shaft 12 and the lower pin shaft 9.
