As shown in fig. 1, the fall arrest device of the present patent is designed on a conventional rail type hydraulic lifting work platform. The structure of the rail type hydraulic lifting platform is disclosed in patent No. 201620721113.5.
Unlike patent No. 201620721113.5, the rail-type hydraulic lift work platform of this patent does not include the fall arrest device of patent No. 201620721113.5, but rather employs the fall arrest device of this patent.
For convenience of description, the rail type hydraulic lifting work platform comprises a frame, a work table 1 moving up and down along the frame, and a hydraulic lifting device located above the work table 1. The frame comprises a top frame 3, a bottom plate 4 and a vertical column 5 for connecting the top frame 3 and the bottom plate 4, and the hydraulic lifting device comprises an oil cylinder and an oil cylinder guide frame 2.
As shown in fig. 1 and 2, the fall preventing device comprises a wire rope 6 and steering wheels, wherein the steering wheels comprise a first steering wheel 7, a second steering wheel 8, a third steering wheel 9 and a fourth steering wheel 10, and one end of the wire rope 6 is fixed on the top frame 3 and is fixed as a dead point 11. The other end of the steel wire rope extends downwards, extends through a first steering wheel 7 fixed on the oil cylinder guide frame 2, turns 180 degrees, then turns 90 degrees upwards through a second steering wheel 8 fixed on the top frame 3, then turns 90 degrees through a third steering wheel 9 fixed on the top frame 3 and on the side opposite to the second steering wheel 8, turns 180 degrees downwards to a fourth steering wheel 10 fixed on the bottom plate 4 or the ground, then extends upwards and is fixed on the working table top 1, and the other end of the steel wire rope 6 is fixed on the working table top 1 as a dead point 11.
In a first embodiment, as shown in fig. 3, the fall protection device comprises a steel cable 6, a set of steering wheels comprising a first steering wheel 7, a second steering wheel 8, a third steering wheel 9 and a fourth steering wheel 10, wherein the four steering wheels are located in the same vertical plane. The four steering wheels are fixed pulleys and are fixed through a support.
The first steering wheel 7, the second steering wheel 8, the third steering wheel 9 and the fourth steering wheel 10 are respectively installed and fixed at the middle position of the oil cylinder bogie, the second steering wheel 8 and the third steering wheel 9 are respectively installed at the middle positions of two sides of the top frame 3, and the fourth steering wheel 10 is installed at the middle position of one side of the corresponding working table surface 1. Namely, the anti-falling device is arranged at the middle plane position of the guide rail type hydraulic lifting operation platform.
In the second embodiment, as shown in fig. 4, there are two wire ropes 6, and there are two sets of steering wheels, each set includes a first steering wheel 7, a second steering wheel 8, a third steering wheel 9, and a fourth steering wheel 10, and each wire rope 6 corresponds to one set of the first steering wheel 7, the second steering wheel 8, the third steering wheel 9, and the fourth steering wheel 10. One dead point of one of the steel wire ropes is fixed on the rear side of the top frame, and the other dead point is fixed on the front side of the working table; one dead point of one end of the other steel wire rope is fixed on the front side of the top frame, the dead point of the other end of the other steel wire rope is fixed on the rear side of the working table, and the steering wheels corresponding to the two steel wire ropes are also correspondingly arranged. Two steel wire ropes and two corresponding steering wheels are symmetrically arranged close to the oil cylinder, and the two steering wheels are respectively positioned in two vertical planes, so that the working table surface 1 is balanced and prevented from falling as much as possible.
The specific working principle is as follows:
the working table top 1 is lifted by a hydraulic cylinder to lift an oil cylinder guide frame 2, and the oil cylinder guide frame 2 pulls the working table top 1 to realize lifting through a chain 12; when the working table top 1 descends, the working table top 1 falls by the self weight of the working table top 1. If the work table surface 1 is blocked and stops descending in the descending process, the oil cylinder guide frame 2 above the work table surface 1 can continuously descend due to the self-weight action, and at the moment, the chain 12 arranged between the oil cylinder guide frame 2 and the work table surface 1 can be loosened. After overcoming the factor that hinders table surface 1 to fall by the dead weight, table surface 1 can fall fast completely, and the violent whereabouts of table surface 1 can cause goods or personnel injury, and chain 12 also can be pulled apart and cause the damage of equipment.
After the mechanical anti-falling device is adopted, the working table surface 1 and the oil cylinder guide frame 2 realize the linkage in the same direction due to the connection of the steel wire rope 6, namely the working table surface 1 stops descending, the oil cylinder guide frame 2 also stops descending, and the chain 12 continues to maintain the upward tension on the working table surface 1. Even if the work table top 1 accidentally stops descending due to the descending, after the factor causing the work table top 1 to be blocked is removed, the work table top 1 can slowly descend under the traction action of the chain 12 and the oil cylinder guide frame 2, and the goods or the personnel cannot be injured.
The anti-falling function of the working platform can be realized by matching one or two sets of steel wire ropes 6 with the steering wheel, and the anti-falling device is simple in structure, convenient to install and low in manufacturing cost.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements of the present invention may be made by those skilled in the art without departing from the spirit of the present invention, which is defined by the appended claims.
