The left side wall and the right side wall of the U-shaped support I01 are provided with a first mounting hole 07 and a first shaft hole 09, the inner end of the first rotating shaft 04 penetrates through the first shaft hole 09 to be fixedly connected with the flange plate 06, and the flange plate 06 is fixed on the inner side wall of the U-shaped support I01 through bolts and the first mounting hole 07. And a second shaft hole 010 is formed in the left side wall and the right side wall of the U-shaped support II 02, and the outer end of the first rotating shaft 04 penetrates through the second shaft hole 10 to be connected with a driving device. And bearings are arranged between the first rotating shaft 04 and the first shaft hole 09 and between the first rotating shaft 04 and the second rotating shaft 010, so that friction between the first rotating shaft 04 and the first U-shaped support 01 and between the first U-shaped support 02 and the second U-shaped support 02 during rotation is reduced. The outer end of the first rotating shaft 04 is connected with a first driving device, and the first rotating shaft 04 can be driven to rotate around the axis of the first rotating shaft 04 along the X axis, so that the first U-shaped support 01 is driven to adjust the pitching angle along the front-back direction.

The second rotating shaft 05 is fixed at the bottom of the second U-shaped support 02, the second rotating shaft 05 is arranged along the Y axis, and the second rotating shaft 05 is connected with a second driving device (not shown in the figure) and driven to rotate around the axis of the second driving device.

The up-down pitching angle of the working lamp is adjusted automatically according to the height signal of the fork, and the left-right inclination angle is adjusted through manual control of a switch.

The signal acquisition unit mainly comprises a sensor, the sensor can be a length sensor or a position sensor, or the combination of the length sensor and the position sensor, and the number of the sensors is a plurality. In some embodiments, the length sensor may measure the height H of the fork as it is raised relative to the mast directly, or by measuring the extension or retraction of the lift cylinders to calculate the height H of the fork as it is raised relative to the mast. The controller is connected with the sensor, the working lamp and the angle adjusting device, and correspondingly adjusts the pitching angle and the left and right inclination angles of the working lamp to appropriate positions through the angle adjusting device by reading the lifting stroke of the fork frame detected by the sensor.

In embodiment 1, taking the portal work light 6 as an example, after the portal work light 6 is installed, the lamp faces the advancing direction of the vehicle. As shown in fig. 7, assuming that the illumination plane of the lamp is perpendicular to the vehicle traveling direction, the lamp illumination plane position is referred to as an initial position. The fork is located at the lowest limit position of the portal, the lifting height of the fork is recorded as H1, the controller adjusts the angle adjusting device to enable the portal working lamp to tilt forwards to a proper angle, the proper angle is recorded as alpha, and the maximum or the proper lighting effect can be obtained at the moment. When the fork is positioned at the uppermost limit position of the portal, the lifting height of the fork is recorded as H2, the working lamp angle of the portal is adjusted to enable the working lamp to lean backwards to a proper angle, and the working lamp angle is recorded as beta, so that the maximum or the most proper lighting effect can be obtained.

The elevation angles of the corresponding gantry working lamps when the fork is at the lowest limit position and the uppermost limit position are determined, the corresponding working lamp angle A can be linearly corresponding to the height between H1 and H2, namely, a relational expression of the fork frame lifting stroke and the working lamp elevation angle can be obtained and stored in the controller, and when the controller actually reads the fork frame lifting stroke detected by the length sensor, the angle of the gantry working lamp 6 to be elevated at the moment is calculated through derivation of the relational expression, so that the angle adjusting device is controlled to adjust the gantry working lamp 6 to the corresponding angle.
