Abstract
Description
Technical Field
[0001] The utility model relates to the field of cameras, in particular to a crane camera. Background Art
[0002] Cranes are a type of lifting and handling machinery that is widely used in ports, workshops, power plants, construction sites, and other places. When the relative height between the crane hook and the object being lifted is very large, the crane operator often cannot see the hook operation due to the obstruction of various obstacles, and needs a ground guide to direct the operation, which brings great inconvenience and danger to the crane operation. With the development and popularization of cameras, more and more cranes are also equipped with cameras, which guide the crane driver to operate through the camera shooting pictures, so that the crane operator will be able to perform lifting operations more conveniently and safely. The current camera mainly includes a base fixed on the boom, ball bearings are installed in the mounting holes of the two side plates of the base, and the rotating shaft passes through the ball bearings in the mounting holes of the two side plates of the base, and is installed in the ball bearings through clearance fit, and then the camera body is fixed on the rotating shaft between the two side plates of the base. In order to prevent the camera body and the rotating shaft from rotating on the ball bearings when the crane is operating, the existing technology is to install a damper on the rotating shaft of the outer plate of the base, and limit the rotation of the rotating shaft relative to the ball bearings through the damper, thereby preventing the camera body from rotating on the ball bearings with the rotating shaft when the crane is operating, so that the picture taken by the camera is prone to shaking and becoming blurred, resulting in slow operation or even failure to operate smoothly. However, the rotating shaft is installed in the ball bearings through clearance fit, and there is a risk of the camera body and the rotating shaft falling off in the axial direction when the crane is operating. Utility Model Content

[0005] The crane camera described in the utility model is prevented from falling off due to relative displacement of the shaft and the camera body in the axial direction due to the shaft being installed in the bearing through clearance fit when the crane is in operation; in addition, due to the presence of the thrust ring and the damper on the side plate side, the thrust ring and the damper are in rigid contact with the side plate side, which can easily transmit vibrations in the axial direction of the shaft, making the picture taken by the camera easily shake slightly and become blurred, therefore, a shock absorbing ring is installed between the damper and the side plate and between the thrust ring and the side plate, and the installation gaps of the damper, the side plate and the thrust ring are filled by the shock absorbing ring, thereby reducing the axial movement (vibration) of the camera body when the crane is in operation.
[0006] As a preferred solution of the utility model, the thrust ring comprises an upper half ring and a lower half ring, and the upper half ring is connected to the lower half ring by bolts and is clamped and fixed on the rotating shaft.
