Technical field

The present invention relates to lifting device fall arrest technical fields, and in particular to a kind of guide rail-type lifting platform fall arrest dress It sets.

Background technique

Guide rail-type lifting platform includes hoistable platform, guide rail, oil cylinder, and the upper end of the piston rod of oil cylinder and hoistable platform connect It connects, hoistable platform is along lifting rail.

When needing to carry out the operations such as repair and maintenance to guide rail-type lifting platform, need to shut down for passing through oil pipe toward oil cylinder The oil pump of middle transmission hydraulic oil, after oil pump is shut down, in-oil cylinder hydraulic oil no longer changes, so that the position of in-oil cylinder piston rod No longer change, to make hoistable platform stop lifting, at this point, the lower section that operating personnel arrives hoistable platform again carries out operation.

But as oil pipe uses the growth of time, or there are the situations such as oil pipe quality is low, once pipeline rupture, it will The loss for causing in-oil cylinder hydraulic oil causes in-oil cylinder piston rod to decline, to hoistable platform can be allowed to lose piston rod It supports and falls；Or the piston rod of oil cylinder and the junction fatigue of hoistable platform are loosened, are broken, and cause hoistable platform unexpected It falls.The personal safety that the operating personnel below hoistable platform will be jeopardized, causes safety accident.

So how to prevent hoistable platform from falling suddenly, improve operation safety, be those skilled in the art urgently The technical issues of solution.

Summary of the invention

The present invention In view of the above shortcomings of the prior art, proposes a kind of guide rail-type lifting platform falling proof device, this Invention can prevent hoistable platform from falling suddenly, improve operation safety.

To achieve the goals above, the technical solution adopted by the present invention is that:

A kind of guide rail-type lifting platform falling proof device, including fixed plate, rotary connection plate, support rod, fixed plate with lead The guide rail of rail hoistable platform connects, and one end of rotary connection plate and fixed plate are hinged, rotary connection plate far from fixed plate one It holds hinged with support rod.

Further, the fixed plate is equipped with guide rod close to the side of rotary connection plate, and rotary connection plate is equipped with and is used for With the guiding slide opening of the arc of guide rod cooperation.

Further, the fixed plate is equipped with first positioning hole, and rotary connection plate is equipped with for being connected to first positioning hole Second location hole, first positioning hole and second location hole cooperate with locating rod.

Further, further include only guard's valve below the fixed plate, only guard's valve is connect with guide rail, only guard's valve and Rotary connection plate cooperation, only guard's valve is electrically connected with oil pump.

Further, the guide rail-type lifting platform includes two rows of guide rails, the hoistable platform between two rows of guide rails, peace Loaded on the oil cylinder on cylinder bracket, guide rail and cylinder bracket are all set on base, and the upper end of the piston rod of oil cylinder, which is equipped with, to be promoted Seat, the both ends of upgrade block are equipped with the first roller mount, and the first roller mount is equipped with the idler wheel for rolling along guide rail, the first upgrade block It is connect by chain with hoistable platform.

Further, the hoistable platform is equipped with guardrail.

Further, the hoistable platform is equipped with the second roller mount close to the side of guide rail, and the second roller mount is equipped with and is used for The second idler wheel rolled along guide rail.

The invention has the benefit that

1, the present invention can be during the lower section of operating personnel to hoistable platform carries out operation, even if it is flat that lifting occurs The dangerous situation that platform falls suddenly remains to the support for allowing hoistable platform to be supported bar, prevents the whereabouts of hoistable platform, to ensure The personal safety of operating personnel below hoistable platform, avoids safety accident, improves operation safety.

It 2, can be in rotary connection plate with the hinged of rotary connection plate and fixed plate by setting guide rod and guiding slide opening When place is centre of gyration rotation, guide rod can be connected in guiding slide opening along guiding slide opening sliding to limit rotation The rotary motion trace of fishplate bar improves the accuracy and reliability of rotary connection plate rotation.

3, by setting locating rod, first positioning hole, second location hole, can prevent when support rod is in softened state Only rotary connection plate continues to rotate by the centre of gyration of the hinged place of rotary connection plate and fixed plate, to improve support rod branch Support the stability of hoistable platform.

4, guard's valve is stopped by setting, hoistable platform can either be allowed to be supported the support of bar, prevent the prominent of hoistable platform So fall, additionally it is possible to while support rod struts, oil pump can be shut down, hoistable platform is prevented to act, it is simple and efficient to handle.

5, by setting guardrail, the personnel on hoistable platform and the safety of article be can be improved.

6, it by the second roller mount of setting and the second idler wheel, can be allowed during hoistable platform is gone up and down with chain Hoistable platform can only be moved along the vertical direction where guide rail, and cannot be shaken, to realize the guiding to hoistable platform Effect, improves the stability that hoistable platform is gone up and down with chain.
