Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, and in particular to a tilt detection sensor for the lifting frame of a tower crane. Background Technology

[0002] The tilt detection sensor for the tower crane lifting frame is a key device to ensure the safe operation of the tower crane. It is mainly used to monitor the tilt status of the lifting frame in real time to prevent the tower crane from overturning due to excessive tilt.

[0003] Existing tower crane lifting frame tilt detection sensors typically weld the sensor bracket to the lifting frame as a single unit, forming a rigid connection. This allows the sensor to be fixed for a long time without frequent adjustments. However, since the sensor operates on the outside for extended periods, it is susceptible to damage from harsh environments. Once the sensor is damaged, it needs to be replaced. However, disassembly and replacement require tools to remove the welded tilt detection sensor and then re-weld a new sensor, which is time-consuming, labor-intensive, and increases the workload of the staff.

[0023] Reference Figure 1-4 This utility model provides a tower crane lifting frame tilt detection sensor, which includes a lifting frame block 1. A fixing block 2 is fixedly connected to the front side of the lifting frame block 1. There are two fixing blocks 2. A groove 3 is opened on the upper side of the fixing block 2. A sensor device 4 is arranged inside the groove 3. An installation structure 5 is provided on the upper side of the fixing block 2. The sensor device 4 is slidably connected to the fixing block 2 and the lifting frame block 1.

[0024] The mounting structure 5 includes a rotating groove 501, which is located on the upper side of the left-side fixing block 2. A rotating shaft 502 is installed inside the rotating groove 501. A blocking block 503 is fixedly connected to the upper end of the rotating shaft 502, and a square block 504 is fixedly connected to the lower side of the blocking block 503. A square hole 505 is provided on the front side of the square block 504. A sliding groove 506 is provided on the front side of the right-side fixing block 2, and a spring 507 is installed inside the sliding groove 506. The rear end of the spring 507 is fixedly connected to the right-side fixing block 2, and a square plate 508 is fixedly connected to the front end of the spring 507. A locking block 509 is fixedly connected to the front side of the square plate 508. The lower end of the rotating shaft 502 is rotatably connected to the left-side fixing block 2. The blocking block 503 and the fixing block 2 are slidably connected, as are the square plate 508 and the right-side fixing block 2. The square block 504 is located inside the sliding groove 506, and the locking block 509 is located inside the square hole 505 and is connected to the square block 504. A sliding connection is provided, with square plate 508 and square block 504 movably connected. A telescopic rod 510 is provided inside spring 507. The front end of telescopic rod 510 is fixedly connected to square plate 508, and the rear end of telescopic rod 510 is fixedly connected to the right-side fixing block 2. A square groove 511 is provided on the lower side inside the sliding groove 506. A limit block 512 is provided inside the sliding groove 506. A threaded rod 513 is rotatably connected to the lower side of the limit block 512. The lower end of the threaded rod 513 passes through the right-side fixing block 2 and is fixedly connected to a cylindrical block 514. The limit block 512 is located inside the square groove 511 and is slidably connected to the right-side fixing block 2. The threaded rod 513 is threadedly connected to the right-side fixing block 2. A sliding groove 515 is provided on the left side inside the sliding groove 506 and the left side inside the square groove 511. A slider 516 is provided inside the sliding groove 515. The slider 516 is fixedly connected to the limit block 512 and slidably connected to the right-side fixing block 2.

[0025] The PLC controller and sensor device 4 are electrically connected to facilitate the operation of the control components. When sensor device 4 is damaged, the mounting structure is opened for replacement. At this time, the operator holds the cylindrical block 514, causing the threaded rod 513 to rotate. The threaded rod 513 rotates and moves downwards, moving the limit block 512 into the square groove 511. Simultaneously, the limit block 512 moves, causing the slider 516 to slide in the sliding groove 515. The slider 516 is designed to ensure that the limit block 512 slides accurately into the square groove 511. After the positioning block 512 fully slides into the square groove 511, the spring 507, which is in a compressed state, will stretch and move the square plate 508 since it is no longer restrained by the limiting block 512. The movement of the square plate 508 will move the locking block 509 and the square block 504 outside the locking block 509. Then, when the locking block 509 slides out of the slide groove 506, it will also slide out of the square hole 505. Then, as the square block 504 moves, it will bring the blocking block 503 and rotate with the rotating shaft 502. After removing the restriction on the upper side of sensor device 4, the operator can slide sensor device 4 out of groove 3 and replace it with a new one. Then, the operator pushes the blocking block 503 to rotate and move with the rotating shaft 502, and then slides the square block 504 into the slide groove 506. Then, the locking block 509 slides into the square hole 505. Then, the square block 504 drives the square plate 508 to compress the spring 507 and move. At the same time, the operator holds the cylindrical block 514 and rotates it, so that the cylindrical block 514 drives the threaded rod 513 to rotate and move, pushing the limit block 512 to move, and then restricting the extension of the spring 507. In this way, the blocking block 503 is fixed. During the extension and compression of the spring 507, while moving the square plate 508, the telescopic rod 510 extends and compresses. The telescopic rod 510 increases the stability of fixing sensor device 4. The setting of fixing block 2 and mounting structure 5 makes it easy for the operator to disassemble and replace the sensor without the aid of tools when the sensor is damaged, saving time and effort, making it convenient and quick, and reducing the workload of the operator.

[0026] Working principle: The operator installs two identical fixing blocks 2 on the front side of the lifting frame block 1. Then, the operator opens the blocking block 503 of the installation structure 5 and slides the sensor device 4 into the groove 3 of the fixing block 2. The operator then fixes the blocking block 503. During operation, the sensor device 4, based on MEMS or electrolyte principle, outputs a tilt angle signal by sensing changes in the direction of gravity, and then detects the tilt angle. It can be fixed on the four sides of the lifting frame block 1 to comprehensively monitor the tilt angle. When the sensor device 4 is damaged due to long-term operation, the operator opens the limiting block 512, and the square block 504 of the blocking block 503 slides out of the slide groove 506. The operator then replaces the damaged sensor device 4 in the groove 3 with a good one, and then uses the limiting block 512 to fix the square block 504 that has slid into the slide groove 506, so that the blocking block 503 fixes the upper side of the sensor device 4.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
