Description

Technical Field

[0001] This utility model relates to the field of anti-fall beam installation technology, specifically an anti-fall beam installation lifting platform tooling. Background Technology

[0002] Anti-fall beams are an important safety measure in construction engineering, primarily aimed at preventing beam collapse during construction or use due to improper stress, material defects, or environmental factors. During installation, a step exists at the pier installation location, requiring the use of a support frame to align its upper surface with the installation position. The beam is then manually pushed to the installation location. However, these support frames are mostly fixed structures with limited height adjustment, making them unsuitable for installation locations with varying pier step heights. Furthermore, the manual pushing process is labor-intensive. Therefore, we propose an anti-fall beam installation lifting platform to address these issues. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1-5As shown, this utility model provides a lifting platform fixture for preventing beams from falling, including a base 1, a lifting platform 2 at the top of the base 1, a lifting mechanism 3 between the top of the base 1 and the bottom of the lifting platform 2, a moving platform 4 at the top of the lifting platform 2, and positioning mechanisms 5 at the four corners of the side of the base 1; moving wheels 11 are fixedly installed at the four corners of the bottom of the base 1, which facilitates the translation of the entire lifting platform fixture; and hanging ears 12 are fixedly installed at the four corners of the side of the base 1, which facilitates the hoisting of the entire lifting platform fixture.

[0024] The positioning mechanism 5 includes an L-shaped seat 51, which is fixedly installed on the side of the base 1. An inner threaded cylinder 52 is fixedly clamped at the end of the L-shaped seat 51 away from the base 1. A lifting bolt 53 is threaded in the middle of the inner threaded cylinder 52. A support sleeve 54 is fixedly installed at the bottom of the lifting bolt 53. A torsion block 531 is fixedly installed at the top of the lifting bolt 53. When the entire lifting platform fixture is moved to a suitable position, the torsion block 531 is rotated using an external tool to control the rotation of the lifting bolt 53, driving the support sleeve 54 to descend, so that the lower surface of the support sleeve 54 contacts the ground, improving the stability of the entire lifting platform fixture after movement. Furthermore, the lifting platform fixture can be adjusted to a horizontal position by adjusting the descent depth of each support sleeve 54, facilitating the stable installation of the subsequent anti-fall beam.

[0025] The lifting mechanism 3 includes two symmetrically distributed first seats 31 and two symmetrically distributed second seats 32. The first seats 31 are fixedly installed at the top of the base 1, and the second seats 32 are fixedly installed at the bottom of the lifting platform 2. A first inclined frame 33 is rotatably mounted on the top of each of the first seats 31, and a second inclined frame 34 is rotatably mounted on the bottom of each of the second seats 32. The first inclined frames 33 and the second inclined frames 34 are staggered. A rotating horizontal shaft 35 is rotatably mounted at the intersection of the first inclined frames 33 and the second inclined frames 34. A first roller 331 is rotatably mounted on the top of the first inclined frame 33, and the first roller 331 contacts the bottom of the lifting platform 2. A second roller 341 is rotatably mounted on the bottom of the second inclined frame 34, and the second roller 341 contacts the top of the base 1. A first horizontal shaft 36 is fixedly mounted on the bottom of the two second inclined frames 34, and a third seat 361 is rotatably mounted in the middle of the first horizontal shaft 36. A second horizontal shaft 37 is fixedly installed in the middle of the frame 33. A fourth seat 371 is rotatably installed in the middle of the second horizontal shaft 37. A first hydraulic cylinder 38 is fixedly installed at the top of the third seat 361. The drive end of the first hydraulic cylinder 38 is fixedly installed with the fourth seat 371. By controlling the opening of the first hydraulic cylinder 38 to extend, the distance between the first horizontal shaft 36 and the second horizontal shaft 37 is increased, causing the first inclined frame 33 and the second inclined frame 34 to rotate alternately, thereby driving the lifting platform 2 to rise. Conversely, by controlling the opening of the first hydraulic cylinder 38 to retract, the distance between the first horizontal shaft 36 and the second horizontal shaft 37 is decreased, causing the first inclined frame 33 and the second inclined frame 34 to rotate alternately, thereby driving the lifting platform 2 to descend. This allows for flexible adjustment of the height position of the lifting platform 2, making it easy to adapt to pier steps of different heights, so that the upper surface of the lifting platform 2 is flush with the pier steps, thus improving the installation flexibility of the anti-fall beam.

[0026] The bottom end of the lifting platform 2 is fixedly installed with a first locking frame 332 corresponding to the first roller 331. The first roller 331 is movably locked in the corresponding first locking frame 332. By setting the first locking frame 332, the stability of the movement of the first roller 331 is increased. The top end of the base 1 is fixedly installed with a second locking frame 342 corresponding to the second roller 341. The second roller 341 is movably locked in the corresponding second locking frame 342. By setting the second locking frame 342, the stability of the movement of the second roller 341 is increased.

[0027] The bottom four corners of the mobile platform 4 are each fixedly equipped with a third roller 41. The top of the lifting platform 2 is fixedly equipped with a third clamping frame 42 corresponding to the third roller 41. The third roller 41 is movably clamped in the corresponding third clamping frame 42. The top of the lifting platform 2 is fixedly equipped with two symmetrically distributed limiting frames 43. The lifting platform 2 is movably clamped between the two limiting frames 43. The top of the lifting platform 2 is fixedly equipped with two symmetrically distributed sets of hydraulic cylinder brackets 44. Each set of hydraulic cylinder brackets 44 is fixedly equipped with a second hydraulic cylinder 45. The drive end of the second hydraulic cylinder 45 is fixedly equipped with an installation support 46. The installation support 46 is fixedly installed on the side of the mobile platform 4. When it is necessary to push the anti-fall beam for installation, the anti-fall beam is hoisted and placed on the mobile platform 4. By controlling the opening of the second hydraulic cylinder 45, the mobile platform 4 is driven to move horizontally, so that the mobile platform 4 is moved to the installation position of the pier step. No manual pushing is required, saving manpower.

[0028] Working principle: The entire lifting platform fixture is moved horizontally using the moving wheels 11 to a suitable position. Once the fixture is in the correct position, the external tool is used to rotate the torsion block 531 to control the rotation of the lifting bolt 53, which drives the support sleeve 54 to descend, making the lower surface of the support sleeve 54 contact the ground. The lifting platform fixture can be adjusted by adjusting the descent depth of each support sleeve 54 to achieve a horizontal position, facilitating the stable installation of the anti-fall beam.

[0029] Subsequently, the anti-fall beam is hoisted and placed on the mobile platform 4. According to the height of the pier step, the height position of the lifting platform 2 is adjusted. By controlling the extension of the first hydraulic cylinder 38, the distance between the first horizontal shaft 36 and the second horizontal shaft 37 is increased, which drives the first inclined frame 33 and the second inclined frame 34 to rotate alternately, thereby driving the lifting platform 2 to rise. Conversely, by controlling the retraction of the first hydraulic cylinder 38, the distance between the first horizontal shaft 36 and the second horizontal shaft 37 is decreased, which drives the first inclined frame 33 and the second inclined frame 34 to rotate alternately, thereby driving the lifting platform 2 to fall. Thus, the height position of the lifting platform 2 can be flexibly adjusted so that the upper surface of the lifting platform 2 is flush with the pier step.

[0030] Subsequently, by controlling the activation of the second hydraulic cylinder 45, the mobile platform 4 is driven to move horizontally, so that the mobile platform 4 is moved to the installation position of the pier step, without the need for manual pushing, thus saving manpower.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
