A push plate is installed on one side of the cavity plate. A dual-axis motor is installed inside the crane trolley. First support rods are installed at both ends of the dual-axis motor. A second support rod is rotatably connected to the inside of the crane trolley via a shaft. Transmission wheels are installed on the outer surfaces of both the first and second support rods. Rollers are installed at the ends of both the first and second support rods. A track groove is formed inside the crane main beam.

[0008] Optionally, the rollers and the cavity block are both located inside the track groove, and the bottom of the push plate abuts against the inner wall of the track groove.

[0009] Optionally, the cavity block has a rectangular groove with the left and right directions as the depth direction and the front and back directions as the length direction. The end of the rectangular slider is located inside the rectangular groove, and the rectangular slider can slide along the length direction of the rectangular groove.

[0010] Optionally, the positions of the positioning pulleys and the laser rangefinder correspond to the positions of the fixed plate. There are several positioning pulleys, which are located on both sides of the fixed plate.

[0013] This utility model provides an automatic positioning device for crane operation, which has the following beneficial effects:

[0014] 1. The crane's automatic positioning device, through the arrangement of a cavity block, electric push rod, laser rangefinder, U-shaped plate, and positioning pulley, enables the crane to conveniently position and adjust the crane trolley's position for correction. Two laser rangefinders detect the distance to the fixed plate; when the deviation between the two rangefinders exceeds the error range, the position of the positioning pulley is adjusted. This allows the positioning pulley to push against the fixed plate, thereby adjusting the crane trolley's position, facilitating positioning and correction, improving movement stability, and ultimately enhancing practicality.

[0015] 2. The crane's automatic positioning device, through the arrangement of strip blocks, rectangular sliders, return springs, and push plates, facilitates the cleaning of dust and debris in the track groove, improves the stability of the crane trolley during operation, and allows the push plate to clean the dust in the track groove as the crane trolley moves. When the crane trolley is correcting its course, the return spring prevents the push plate and cavity block from rigidly colliding with the inner wall of the track groove, thus improving practicality.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1 to 8 This utility model provides a technical solution: an automatic positioning device for crane operation, including a crane main beam 1, a crane trolley 2, a fixed plate 3, and a cavity block 4. An electric push rod 5 and a laser rangefinder 6 are installed inside the crane trolley 2. A U-shaped plate 7 is installed at the movable end of the electric push rod 5. A positioning pulley 8 is rotatably connected inside the U-shaped plate 7 via a shaft. Strip blocks 9 are installed at the front and rear of the crane trolley 2. Rectangular sliders 10 are installed on both sides of the strip blocks 9. A return spring 11 is installed inside the cavity block 4. A push plate 12 is installed on one side of the cavity plate. A dual-axis motor 13 is installed inside the crane trolley 2. First support rods 14 are installed at both ends of the dual-axis motor 13. A second support rod 15 is rotatably connected inside the crane trolley 2 via a shaft. Transmission wheels 16 are installed on the outer surfaces of both the first and second support rods 14. Rollers 17 are installed at the ends of both the first and second support rods 14 and 15. A track groove 18 is opened inside the crane main beam 1.

[0028] Specifically, the roller 17 moves inside the track groove 18, and the push plate 12 moves with the crane trolley 2, thereby pushing away dust and debris in the track groove 18 and avoiding affecting the movement of the crane trolley 2.

[0029] Please see Figures 2 to 7 The roller 17 and the cavity block 4 are both located inside the track groove 18, and the bottom of the push plate 12 abuts against the inner wall of the track groove 18.

[0030] Specifically, the rectangular slider 10 moves along the length of the rectangular groove, which facilitates the movement of the strip block 9 relative to the cavity block 4 and avoids rigid collisions between the cavity block 4 and the push plate 12 and the inner wall of the track groove 18.

[0031] Please see Figures 2 to 4 The cavity block 4 has a rectangular groove with the left and right directions as the depth direction and the front and back directions as the length direction. The end of the rectangular slider 10 is located inside the rectangular groove, and the rectangular slider 10 can slide along the length direction of the rectangular groove.

[0032] Specifically, the distance is detected by a laser rangefinder 6, and the movement is adjusted and assisted by guide pulleys.

[0033] Please see Figures 2 to 8 The positions of the positioning pulley 8 and the laser rangefinder 6 correspond to the positions of the fixed plate 3. There are several positioning pulleys 8, which are located on both sides of the fixed plate 3.

[0034] Specifically, this facilitates the synchronous rotation of the first support rod 14 and the second support rod 15, and facilitates the movement of the roller 17 inside the track groove 18.

[0035] Please see Figures 5 to 6 The first support rod 14 is rotatably connected to the crane trolley 2 via a bearing. There are several transmission wheels 16, and adjacent transmission wheels 16 are connected by a transmission chain.

[0036] Specifically, this facilitates the movement of the lifting trolley 2 along the length of the fixed plate 3, thereby facilitating the detection of the distance by the laser rangefinder 6.

[0037] Please see Figures 1 to 8 The fixing plate 3 is fixedly connected to the main beam 1 of the crane. The length of the fixing plate 3 is less than the length of the main beam 1 of the crane, and the length direction of the fixing plate 3 is parallel to the length direction of the main beam 1 of the crane.

[0038] In operation, the trolley 2 moves within the track groove 18 on the main beam 1 of the crane. The dual-shaft motor 13 drives the first support rod 14 to rotate. Adjacent transmission wheels 16 are connected by a transmission chain, causing the second support rod 15 to rotate synchronously with the first support rod 14. This facilitates the movement of multiple rollers 17 within the track groove 18, thus facilitating the movement of the trolley 2. The distance between the fixed plates 3 is detected by two laser rangefinders 6. When the deviation in the number detected by the two laser rangefinders 6 exceeds the error range, the movable end of the electric push rod 5 extends or retracts, causing the positioning pulley 8 to abut against the fixed plate 3, thereby moving the trolley 2 relative to the fixed plate 3 and adjusting the position of the trolley 2 for positioning and correction. The push plate 12 moves with the crane trolley 2, which facilitates the push plate 12 to push the dust and debris in the track groove 18, and facilitates the dust to both ends of the track groove 18. This makes it easier to remove the dust and debris in the track groove 18 through the gap between the crane main beam 1 and the fixed plate 3, so as not to affect the movement of the crane trolley 2. When the crane trolley 2 moves to correct its course, the strip block 9 moves with the crane trolley 2 in the front-back direction. The strip block 9 moves relative to the cavity block 4, so that the return spring 11 is compressed or stretched by force, and the rectangular slider 10 slides along the length of the rectangular slide groove, so as to avoid the push plate 12 and the cavity frame from rigidly colliding with the inner wall of the track groove 18 and avoiding damage.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
