Bridge crane encoder installation device

Abstract

The invention discloses a bridge crane encoder installation device. The bridge crane encoder installation device is composed of a guide rail seat, a guide rail, a sliding block, a connecting block, a guide column, an upper pressure spring, a lower pressure spring, an encoder, a coupler, a synchronous wheel and a synchronous belt. The guide rail seat is fixed to an end beam of a bridge crane. The guide rail is installed on the guide rail seat. The sliding block is slidably matched with the guide rail. The connecting block is fixedly connected with the sliding block. The coupler is erected on the connecting block through the guide column. The upper pressure spring and the lower pressure spring are arranged on the guide column in a sleeving mode and located on the upper side and the lower side of the coupler correspondingly. The encoder is fixed to the coupler and is in shaft connection with the synchronous wheel. The synchronous wheel is engaged with the synchronous belt. The synchronous belt is fixed to a beam of a plant. According to the bridge crane encoder installation device, the encoder moving along with the crane is adopted to be combined and fixed to the structure of the plant, thus, the position where a cart is located can be accurately determined through the encoder, the accurate and reliable effects are achieved, and operation is easy, convenient and rapid.

Description

technical field [0001] The invention relates to an encoder installation device of a bridge crane. Background technique [0002] Absolute rotary encoders have been more and more widely used in angle, length measurement and positioning control in various industrial systems because each position is absolutely unique, anti-interference, and does not require power-off memory. It should therefore be feasible to use an absolute rotary encoder to detect the position of the bridge crane in the plant. [0003] Under normal design conditions, the wheel rim of the crane’s cart should maintain a certain gap with the track. Generally, the wheel tread is 40mm wider than the top surface of the track. In addition, the error of the bridge crane track installation is inevitable, and the national standard stipulates that it is a guide rail. The height error is 6-10mm, and the track joint gap is usually 1-2mm. Due to the gap between the wheel rim of the cart and the track, the installation e...

AI Technical Summary

Problems solved by technology

Due to the gap between the wheel rim of the cart and the track, the installation error of the track, the gap between the track joints, etc., during the operation of the cart, the wheels will have axial movement and horizontal runout on the track, which will give the absolute value of rotation. The installation and measurement of the encoder bring inconvenience
