Description

Technical Field

[0001] The invention belongs to the technical field of elevator steel belt detection, and in particular relates to a steel belt detection device for a steel belt elevator. Background Art

[0002] Compared with the old wire rope elevator, the steel belt elevator has a longer service life and can effectively control noise during operation, making the passenger experience more comfortable. Therefore, more and more elevators use steel belts instead of steel wires as the traction medium of the elevator. The steel belt is made of polyurethane wrapped steel wire rope. Since the direct contact between the steel wire and the air is reduced, the risk of rust and wear of the steel wire is greatly reduced, thereby extending the service life. However, due to this structural feature, the internal steel wire cannot be directly observed by the naked eye, making it more difficult to detect than the wire rope elevator. The existing elevator steel belt detection device cannot directly detect the aging of the internal steel wire, and an elevator steel belt detection device is urgently needed to solve the above problem. Summary of the invention

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Reference Figure 1 to Figure 3 , a steel belt elevator steel belt detection device, comprising a mounting plate 1, a mounting mechanism, a steel belt infrared detection mechanism and a bulge detection mechanism, the mounting mechanism comprising a right support frame 2 and a left support frame 3; the steel belt infrared detection mechanism comprises a right connecting rod 4, a left connecting rod 5, and a thermal infrared detector 6, the right connecting rod 4 is fixedly connected to the right side of the thermal infrared detector 6 and is installed at the front end of the right support frame 2, and the left connecting rod 5 is fixedly connected to the left side of the thermal infrared detector 6 and is installed at the front end of the left support frame 3; a front roller 12 is arranged directly below the thermal infrared detection device, and the front roller 12 is fixedly connected to the two support frames by a front roller shaft 11; the bulge detection mechanism comprises a top plate 7, a rear connecting plate 8, a rear lower roller shaft 9, a rear lower roller shaft 10, a rear upper roller shaft 13, a rear upper roller shaft 14, a right roller shaft fixing plate 15, a right spring 16, a left roller shaft fixing plate 17, a left spring 18, and a left end cover 1 9 and right end cover 20; the rear connecting plate 8 is vertically installed on the rear side of the mounting mechanism; the top plate 7 is arranged perpendicular to the rear connecting plate 8; the rear lower roller 9 is arranged at the bottom of the rear side of the mounting mechanism, and the rear lower roller 10 is installed on the rear lower roller 9; the rear upper roller 14 is installed on the rear upper roller 13; the right end of the rear upper roller 13 is connected to the right roller fixing plate 15, and the left end is connected to the left roller fixing plate 17; the bottom of the right spring 16 is fixedly connected to the rear end groove of the right support plate, and the top is fixedly connected to the right roller fixing plate 15; the bottom of the left spring 18 is fixedly connected to the rear end groove of the left support plate, and the top is fixedly connected to the left roller fixing plate 17; the left end cover 19 is arranged directly above the left roller fixing plate and fixedly connected to the left support frame; the right end cover 20 is arranged directly above the right roller fixing plate and fixedly connected to the right support frame.

[0019] In this embodiment, a pressure sensor is provided on the top plate 7. When the steel belt bulges, the rear upper roller 14 is lifted to trigger the pressure sensor, thereby detecting whether bulges occur. The method of fixing the spring limiter by the end cover can facilitate the replacement and installation of the rear upper roller 14, and the size of the bulge detection range can be adjusted by controlling the diameter of the roller, thereby improving the applicability of the device.

[0020] In this embodiment, by installing the device in the machine room, the steel belt passes through the device through the roller during the operation of the elevator, and the thermal infrared detector 6 of the steel belt infrared detection mechanism detects the steel belt to determine the damage of the steel belt. If it is detected that the damage of the steel belt reaches a threshold, the alarm on the detection mechanism sends an alarm signal.

[0021] The working principle of the elevator steel belt detection device is described in detail below: When in use, the installation plate 1 is fixed in a suitable position so that the steel belt slides on the roller. The steel belt first passes through the bulge detection mechanism, and the steel belt is clamped between the rear upper roller 14 and the rear lower roller 10. Since the rear upper roller 13 is connected to the spring stopper, when the steel belt bulges, the height of the rear upper roller 14 will be raised to trigger the pressure sensor, and then the alarm will be transmitted through the alarm device to issue an early warning of the steel belt status. When there is no bulge on the surface of the steel belt and it passes through the bulge detection mechanism smoothly, the steel belt is then detected by the thermal infrared detector 6 of the steel belt infrared detection mechanism to determine the damage of the steel belt. If the damage of the steel belt reaches the threshold, the alarm on the detection mechanism will sound an alarm. In the bulge detection mechanism, the spring stopper is fixed with an end cover to facilitate the disassembly and installation of the roller. By replacing the upper roller and changing the diameter of the upper roller, the bulge degree when the pressure sensor is triggered can be changed, thereby changing the bulge threshold when detecting different steel belts, thereby improving the applicability of the device. The device can be directly installed in the machine room and automatically detect the status of the steel belt during elevator operation to achieve real-time monitoring effect.
