[0002] Overhead crane is an important lifting and transportation equipment in steel mills, used for loading and unloading steel, iron ore, etc. During the loading and unloading process, laser limiters are required to limit the position so that loading and unloading can be carried out at the specified position. However, the current laser limiters are usually fixed and cannot be adjusted according to needs, and the position of the loading and unloading objects is not fixed. Therefore, in the actual loading and unloading process, the driver needs to make adjustments based on experience and cannot load and unload very accurately. Summary of the invention

[0020] The utility model will now be described in further detail with reference to the accompanying drawings.

[0021] like Figure 1-3As shown, a remotely controllable laser limit device for an overhead crane comprises a base 1 and a laser limiter 2. The base 1 is bolted with a support base 3. A rotating plate 4 is rotatably connected inside the support base 3. A horizontal motor 5 is installed at the bottom end of the rotating plate 4. The output end of the horizontal motor 5 passes through the rotating plate 4 and is clamped on the support base 3. Two vertical plates 6 are fixedly connected to the bottom surface of the rotating plate 4. The laser limiter 2 is located between the two vertical plates 6. A vertical motor 7 is fixed on the laser limiter 2. The two shaft ends of the vertical motor 7 are respectively fixed on the two vertical plates 6. The horizontal motor 5 and the vertical motor 7 are wirelessly connected to a joystick type remote control.

[0022] Controlling the operation of a motor by means of a joystick-type remote control is a conventional technical means and is widely used in various industries. Its working principle and wireless connection method will not be described in detail here.

[0023] The base 1 is circular, with a clamping block 8 on the bottom surface thereof, a clamping slot 9 in the clamping block 8 , ear plates 10 on both sides of the base 1 , mounting holes 11 on the ear plates 10 , and a plurality of countersunk holes 12 on the base 1 .

[0024] The slot 9 is used to engage the shift lever 19 , so that the output end of the horizontal motor 5 , that is, the shaft end, is fixed, and the motor end of the horizontal motor 5 rotates, driving the rotating plate 4 to rotate.

[0025] The support seat 3 is annular, and a plurality of fixing plates 13 are provided at the upper end of the support seat 3. The fixing plates 13 are provided with internal thread holes 14. The number and position of the fixing plates 13 correspond to the number and position of the countersunk holes 12. The internal thread holes 14 are internally threaded with hexagon socket bolts 15 passing through the countersunk holes 12. The base 1 is bolted to the support seat 3 through the hexagon socket bolts 15 and the fixing plates 13. An annular clamping ring 16 is provided at the bottom of the support seat 3. The hexagon socket bolts 15 can be hidden in the countersunk holes 12, so as to facilitate installation. The base 1 and the support seat 3 are connected by bolting, which is convenient for disassembly, so that parts can be replaced.

[0026] The rotating plate 4 is circular, and its diameter is smaller than the inner ring diameter of the support seat 3 and larger than the inner ring diameter of the snap ring 16. The rotating plate 4 is provided with a plurality of notches 17, and the position and number of the notches 17 correspond to the position and number of the fixing plate 13, so as to disassemble the rotating plate 4, and the rotating plate 4 can be taken out from the support seat 3 through the notches 17. The rotating plate 4 is threaded with a plurality of bull's eye rollers 18, and the rolling ends of the bull's eye rollers 18 abut against the snap ring 16. When the rotating plate 4 rotates, the bull's eye rollers 18 roll on the snap ring 16, which can reduce friction and thus increase the service life.

[0027] The output end of the horizontal motor 5 is connected with a lever 19, which is located in a slot 9. The shape of the slot 9 matches the outer contour of the lever 19 and the output end of the horizontal motor 5. The horizontal motor 5 is connected to the base 1 through the lever 19 and the slot 9.

[0028] The vertical motor 7 is a dual-axis motor. The two rotating shafts of the dual-axis motor can rotate synchronously.

[0029] The working principle of the utility model is:

[0030] When in use, the utility model is bolted to the overhead crane through the mounting hole 11, and the rocker-type remote control is installed in the driver's cab. When horizontal rotation is required, the horizontal motor 5 is controlled to work through the rocker-type remote control. Since the output end of the horizontal motor 5 is clamped in the clamping groove 9 through the shift lever 19, the motor end of the horizontal motor 5 rotates, driving the rotating plate 4 to rotate. A bull's eye roller 18 is threadedly connected to the bottom of the rotating plate 4. The bull's eye roller 18 rolls on the clamping ring 16 to reduce friction. The rotation of the rotating plate 4 drives the laser limiter 2 to adjust the angle in the horizontal direction.

[0031] When vertical rotation is required, the vertical motor 7 is controlled by the rocker remote control. Since the vertical motor 7 is installed on the laser stopper 2, and the two output ends of the vertical motor 7 are fixed on the vertical plates 6 on both sides, when the vertical motor 7 is working, the laser stopper 2 starts to rotate, thereby adjusting the angle in the vertical direction. The laser stopper 2 itself is electrically connected to the control console in the driver's cab, so the driver can adjust the overhead crane according to the displayed data, thereby accurately loading and unloading materials.

[0032] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.

[0033] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
