DETAILED DESCRIPTION

[0021] The invention will be further described with reference to the accompanying drawings.

[0022] like Figure 1 As shown, an adjustable telescope frame for illumination has a support plate on the top of the bottom support frame, a middle unit placed on the support plate and fixed by set screws around the perimeter, an adjustment unit above the middle unit with an adjustment plate, the adjustment plate and the middle unit being fixed by a lifting screw and a lifting nut, and multiple lifting screws arranged around the circumference of the adjustment plate, the lifting screws passing through the top plate of the adjustment plate and the middle unit in sequence and being fixed by nuts.

[0023] A rotary bearing and a tire seat plate are provided at the center of the upper surface of the adjusting plate. The outer bearing of the rotary bearing is fixed to the adjusting plate, and the inner bearing is fixed to the tire seat plate. A braking device that acts on the outer bearing is provided on the adjusting plate. The braking device consists of a brake plate, rubber, brake base, and brake nut.

[0024] A bottom support frame features an eyeplate for securing the detachable reinforcing legs. Four set screws around the top support plate allow for adjustment of the intermediate and adjusting units' forward, backward, left, and right displacement. The adjusting plate is connected to the intermediate unit via lifting bolts and nuts, allowing for free adjustment of the adjusting unit's vertical displacement. Braking devices are installed on both sides of the adjusting unit, secured to the unit with bolts. A rotary bearing and a mounting plate are located at the center of the adjusting plate's upper surface. The outer bearing of the rotary bearing is fixed to the adjusting plate, while the inner bearing is fixed to the mounting plate. The rotary bearing allows the adjusting plate to rotate freely. The mounting plate is used for temporarily fixing a reference plate or a telescope mount. An independent reference plate is also designed, which can be temporarily fixed to the mounting plate for aligning the stern base point.

[0025] like Figure 2 As shown, the braking device includes a brake base, which is bolted to the adjusting plate. The brake lever passes through the brake base and is secured with a brake nut. An arc-shaped brake plate is fixed to the front end of the brake lever, the curvature of which matches the curvature of the outer bearing. Rubber is laid on the surface of the brake plate, and the rubber is fixed to the brake plate with hexagonal bolts. Tightening the brake nut presses the braking device against the rubber, bringing it close to the rotating bearing and thus preventing the adjusting plate from rotating. The braking device is divided into two halves for easy disassembly, ensuring convenient replacement of easily worn parts such as rubber components. When the braking device is locked, it ensures that the adjusting plate will no longer rotate.

[0026] During assembly, first place the bottom support frame stably, then place the intermediate unit on the support plate, and install the lifting screw onto the intermediate unit using the lifting nut. Assemble the braking device beforehand and install it on both sides of the adjusting unit. Lift the adjusting unit as a whole, pass it through the lifting screw, and secure it with the lifting nut.

[0027] As Figure 2 shown, the use state of the application. The adjustable lighting telescope cradle is placed in the dock, so that the center height is consistent with the axis height. The detachable reinforcing legs on the bottom support frame ensure its stability. The reference plate is connected to the tire seat plate of the adjustment unit by bolts, so that the reference cross scale line on the reference plate is aligned with the tire seat plate reference scale line on the adjustment unit. The center point of the reference plate should be the center of the tire seat plate check circle on the adjustment unit. Adjust the displacement of the middle unit and the adjustment unit front and back and left and right by the top screw on the bottom support frame. Rotate the jack nut according to the height from the ground to the axis to make the adjustment unit height reach the appropriate position. Rotate the adjustment unit to ensure that the tire seat plate plane on it is basically parallel to the stern tube rear end surface, so that the center point of the reference plate is basically consistent with the axis. Lock the brake device, and the adjustment unit will not rotate at this time. Place the total station target center on the reference plate, so that the target center is consistent with the center point on the reference plate. Use the laser (stern base point) emitted by the total station to coincide with the center point of the reference plate. If there is a displacement deviation in height and front and back, it can be adjusted again. After adjustment, lock the top screw nut on the jack screw, and the displacement of the entire adjustment unit height, front and back, left and right, and circumferential direction will not change. Remove the reference plate and install the telescope frame. Use the drawing needle on the telescope frame to check the tire seat plate check circle on the adjustment unit, so as to ensure that the center of the telescope frame coincides with the stern base point, and then make the telescope center coincide with the bow base point, so as to determine the shafting position and perform shaft rudder lighting work. The advantages of the application are quick and simple to use, which can effectively improve the lighting accuracy and ensure the accuracy of the shaft rudder system installation. In addition, due to its reusable and replaceable parts, the cost is reduced.
