Most of existing anti-falling devices applied to lifting operation platforms (particularly, climbing frames) for buildings are provided with a supporting shaft in an anti-falling block, an anti-falling swing needle is rotatably arranged on the supporting shaft, and reset of the anti-falling swing needle is completed by utilizing self weight of the anti-falling swing needle, so that reset of the anti-falling swing needle is completely dependent on the installation angle of the anti-falling block, and insufficient resetting capability of the anti-falling swing needle is caused due to insufficient installation angle of the anti-falling block, so that an anti-falling effect is poor; and climb frame and all need to correct the anti-falling block after promoting or decline at every turn, just can guarantee that anti-falling block installation angle accords with the requirement, it is laborious to take trouble, both needs to increase the cost and influences the construction progress. In order to solve the above technical problems, the following embodiments provide a lifting operation platform anti-falling device for a building.

As shown in fig. 1 to 5, the lifting operation platform anti-falling device for a building provided by the embodiment comprises a support 1 and a guide rail 2, wherein the support 1 is used for being connected to a high-rise building, vertical plates 11 are arranged at the opposite lower ends of the support 1 along the height direction, and the vertical plates 11 are arranged parallel to the height direction; the guide rails 2 are arranged at one side of the support 1 along the length direction at intervals, and the guide rails 2 are arranged on a high-rise building in a sliding manner along the height direction and are used for installing a climbing frame body; specifically, the guide rail 2 is driven by an electric hoist to ascend or descend; five anti-falling rods 21 are preferably uniformly distributed on one side of the guide rail 2 along the width direction along the height direction; a pin shaft 3 is arranged on one side of the vertical plate 11 facing the guide rail 2, and the pin shaft 3 is arranged parallel to the width direction; a blocking tooth 41 is arranged on the pin shaft 3, and one side of the blocking tooth 41 facing the vertical plate 11 is abutted against the side wall of the vertical plate 11; the pin shaft 3 is rotatably provided with a crashing tooth 42, and one end of the crashing tooth 42, which is away from the pin shaft 3, is positioned between two adjacent falling prevention rods 21 and is abutted against and supported on one of the falling prevention rods 21; the pin shaft 3 is sleeved with a torsion spring 43, one end of the torsion spring 43 is connected with the blocking tooth 41, and the other end of the torsion spring is connected with the bumped tooth 42. It can be understood that the height direction and the length direction in this embodiment refer to the height direction and the length direction shown in fig. 1, the width direction and the height direction are perpendicular to each other, and the three form a three-dimensional cartesian coordinate system.

The anti-falling device of the embodiment is characterized in that the crashing teeth 42 are rotatably arranged on the pin shaft 3, and two ends of the torsion spring 43 sleeved on the pin shaft 3 are respectively connected to the blocking teeth 41 and the crashing teeth 42; when the climbing frame body normally ascends along with the guide rail 2 through the electric hoist, the anti-falling rod 21 can upwards prop against the crashed tooth 42, so that the crashed tooth 42 rotates around the pin shaft 3 towards the direction close to the blocking tooth 41 (in a anticlockwise rotating state shown in fig. 2), and finally the anti-falling rod 21 can cross the crashed tooth 42, at the moment, because the blocking tooth 41 is abutted with the vertical plate 11 and cannot rotate, the torsion spring 43 is twisted to store energy, after the anti-falling rod 21 completely crosses the crashed tooth 42, the crashed tooth 42 is not pressed by external force, the energy stored in the twisted torsion spring 43 can be gradually released, the crashed tooth 42 is pushed to rotate and reset around the pin shaft 3 towards the direction far away from the blocking tooth 41, and one end of the crashed tooth 42 away from the pin shaft 3 is reset to be positioned between two adjacent anti-falling rods 21 (in a state shown in fig. 1), so that the reset capability of the crashed tooth 42 is ensured, and the anti-falling effect is improved. And after the climbing frame body is lifted each time, the parts such as the crashed teeth 42, the blocking teeth 41 and the like do not need to be corrected, so that the labor cost can be reduced, and the construction progress can be quickened.

In a specific application, the number of the falling-preventing rods 21 may be reasonably increased or decreased according to the height of the climbing frame body to be lifted, for example, in other embodiments, the falling-preventing rods 21 are three, four, six, seven, ten, and other numbers.

As shown in fig. 1 and 2, in some embodiments of the present utility model, a mounting slot 411 is concavely formed on a side of the blocking tooth 41 facing away from the riser 11, and a connection portion between the bumped tooth 42 and the pin shaft 3 is embedded in the mounting slot 411; the torsion spring 43 is disposed in the mounting slot 411, and one end of the torsion spring 43 is connected to a surrounding wall of the mounting slot 411. When the climbing frame body normally ascends along with the guide rail 2 through the electric hoist, the crashed teeth 42 gradually rotate around the pin shafts 3 towards the direction close to the crashed teeth 42 and are stored in the mounting slots 411 under the action force of the upward pushing of the falling prevention rods 21, so that the overall arrangement structure of the crashed teeth 42, the blocking teeth 41 and the torsion springs 43 is reduced, and the falling prevention device of the embodiment is miniaturized; meanwhile, the torsion spring 43 is hidden in the mounting slot 411, so that the damage caused by external collision to the torsion spring 43 can be effectively avoided, and the service life of the torsion spring 43 is prolonged.

In some embodiments of the present utility model, the blocking tooth 41 is rotatably disposed on the pin shaft 3, and an elastic member is disposed between the blocking tooth 41 and the riser 11; when the fall protection device is in an initial state, one side of the blocking tooth 41, which faces the vertical plate 11 along the length direction, is abutted against the side wall of the vertical plate 11. By arranging the blocking teeth 41 on the pin shaft 3 in a rotating way, an elastic piece is arranged between the blocking teeth and the vertical plate 11; when the climbing frame body normally descends along with the guide rail 2, the anti-falling rod 21 downwards presses the crashing teeth 42, so that the crashing teeth 42, the torsion spring 43 and the blocking teeth 41 rotate together around the pin shaft 3 in a direction away from the vertical plate 11 (clockwise rotating state shown in fig. 4), the anti-falling rod 21 finally passes over the crashing teeth 42, at the moment, the elastic piece can be stretched or compressed to store energy, after the anti-falling rod 21 completely passes over the crashing teeth 42, the torsion spring 43 and the blocking teeth 41 are not pressed by external force, the energy stored by the stretched or compressed elastic piece can be gradually released, the crashing teeth 42, the torsion spring 43 and the blocking teeth 41 are pulled to rotate and reset together around the pin shaft 3 in a direction close to the vertical plate 11, and one end of the crashing teeth 42, which is away from the pin shaft 3, is reset to be positioned between the two adjacent anti-falling rods 21, so that the reset capability of the crashing teeth 42 is ensured, and the anti-falling effect is improved. When the climbing frame body falls down along with the guide rail 2 in a runaway way, firstly the falling prevention rod 21 can downwards press the collision teeth 42, so that the collision teeth 42, the torsion spring 43 and the blocking teeth 41 rotate along with the pin shaft 3 in a direction away from the vertical plate 11 (clockwise rotation state shown in fig. 4), meanwhile, the kinetic energy of the climbing frame body and the guide rail 2 is larger relative to normal falling because the climbing frame body falls down along with the guide rail 2 in a runaway way, so that the time required for the collision teeth 42, the torsion spring 43 and the blocking teeth 41 to rotate along with the pin shaft 3 in a direction close to the vertical plate 11 is longer, the next falling prevention rod 21 falls down and is abutted to the upper end of the blocking teeth 41 before the blocking teeth 41 are separated from the reset between the two adjacent falling prevention rods 21, and at the moment, and the falling prevention rod 21 still abuts against the upper end of the blocking teeth 41 after the expansion amount of the elastic piece reaches a limit, so that the blocking teeth 41 cannot continue to rotate along the direction away from the vertical plate 11 (state shown in fig. 5), so that the falling prevention effect of the climbing frame body and the guide rail 2 cannot be improved.

Specifically, the elastic member is provided as a compression spring 5, one end of the compression spring 5 is connected to the riser 11, and the other end is connected to the blocking tooth 41.

In some embodiments of the utility model, the pin 3 is detachably connected to the riser 11. When at least one of the blocking tooth 41, the crashed tooth 42 or the torsion spring 43 is damaged, so that the falling prevention function cannot be normally performed, the pin shaft 3 provided with the blocking tooth 41, the crashed tooth 42 and the torsion spring 43 can be detached from the riser 11 for replacement or maintenance.

In this embodiment, the detachable connection structure between the pin shaft 3 and the riser 11 is not limited, so as to improve the connection tightness of the two on the basis of ensuring the convenience of assembling and disassembling the two; as shown in fig. 6, preferably, two ends of the pin shaft 3 along the width direction are respectively provided with a mounting heel brace 31, each mounting heel brace 31 is formed with four through holes 311 along the length direction in a penetrating manner, wherein two through holes 311 are arranged in a row, the two rows of through holes 311 are respectively symmetrically arranged about the pin shaft 3 along the height direction, one side of the vertical plate 11, which faces the pin shaft 3, is provided with internal threaded holes corresponding to the through holes 311 one by one, and when assembled, fastening bolts pass through the through holes 311 and are screwed in the corresponding internal threaded holes. Of course, in other embodiments, the detachable connection structure between the pin shaft 3 and the riser 11 may be configured as other structures such as a transition fit type clamping block and a clamping groove.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
