The embodiment of the utility model provides an in adopt following scheme to realize: the safety belt hanging device for the upward climbing of the tower crane comprises a tower crane ladder, wherein a rail with the same length as that of each standard joint is installed on each standard joint of the tower crane ladder, a groove is formed in each rail, a hanging box with a C-shaped cross section is sleeved on each rail, a check mechanism is arranged in each hanging box and comprises a limiting block and a pawl, the top of each pawl is hinged to the upper portion of the inner wall surface of each hanging box, and the limiting block is welded to the upper side, located at the hinged point of the pawl, of the inner wall surface in each hanging box; the groove of the track is internally provided with non-return blocks at equal intervals, and the outer wall of the closed end of the hanging box is connected with safety belts.

In an embodiment of the present invention, the cross-sectional shape of the non-return block is triangular, the short side of the non-return block is welded to the middle of the inner wall of the groove, and the inclined side of the non-return block forms an included angle a with the horizontal plane, where the included angle a =20 ° -70 °.

The utility model discloses an in the embodiment, the pawl towards hang the welding of the surperficial lower part of the closed end of box compression spring's one end, compression spring's the other end welding be in hang the middle part of the closed end internal face of box.

The utility model has the advantages that: the utility model provides a tower machine climbs climbing safety belt cable suspension device, be provided with pawl and stopper, the pawl is provided with compression spring, sets up simultaneously in the track and ends contrary piece, when taking place the personnel that fall and pulling and hang the box whereabouts, the stopper card hinders on the pawl ends contrary piece to the track, prevents that personnel from further falling, plays the guard action.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1 to 6, the utility model provides a safety belt 4 hanging device for climbing on tower crane, which comprises a tower crane ladder 1, wherein each section of standard section of the tower crane ladder 1 is provided with a track 2 with the same length as the standard section, the track 2 is welded on the standard section, and when the standard section is installed, the track 2 is automatically installed into a straight line; a groove is formed in the track 2, a hanging box 3 with a C-shaped section is sleeved on the track 2, a non-return mechanism is arranged in the hanging box 3 and comprises a limiting block 32 and a pawl 31, the top of the pawl 31 is hinged to the upper part of the inner wall surface of the hanging box 3, and the limiting block 32 is welded on the upper side of the hinged point of the pawl 31 on the inner wall surface of the hanging box 3; the grooves of the track 2 are internally provided with backstop blocks 21 at equal intervals, and the outer wall of the closed end of the hanging box 3 is connected with safety belts 4.

Please continue to refer to fig. 3, fig. 4, and fig. 6, in an embodiment of the present invention, the cross-sectional shape of the non-return block 21 is a triangle, the short side of the non-return block 21 is welded to the middle of the inner wall of the groove, the inclined side of the non-return block 21 forms an included angle a with the horizontal plane, the included angle a =20 ° -70 °, when the hanging box goes down, due to the limitation of the limiting block, the pawl cannot rotate clockwise any more, the non-return box moves down to make the non-return block and the limiting block clamp the pawl, and the non-return block and the limiting block act together to prevent the hanging box from.

With continuing reference to fig. 3, 4 and 5, in an embodiment of the present invention, one end of the compression spring 33 is welded to a lower portion of the surface of the pawl 31 facing the closed end of the hanging box 3, the other end of the compression spring 33 is welded to a middle portion of an inner wall surface of the closed end of the hanging box 3, the compression spring makes the pawl move downward all the time, and a right portion of a bottom end of the pawl protrudes out of a rightmost end of the check block all the time, so that the pawl is prevented from moving downward by the check block when moving downward; and when the lifting box moves upwards, the pawl can rotate anticlockwise by a large angle due to lack of limiting of the limiting block, and rotates anticlockwise when being extruded by the check block, so that the pawl compresses the spring, and the check block can smoothly pass through the lifting box.

The utility model discloses the theory of operation below has:

during operation, only the climbing personnel need to hang the safety crane from the bottom, the hanging box penetrates into the rail, the hanging box is taken out when reaching the top, and the hanging box is carried with the climbing personnel when going downwards so as to be used for climbing next time.

When the hanging box falls down accidentally, the limiting block blocks the pawl to the non-return block on the track to prevent further falling of personnel, and the protection effect is achieved.

The above description is only for the preferred embodiment of the present invention, and should not be interpreted as limiting the scope of the present invention, which is intended to cover all the equivalent changes and modifications made in accordance with the claims of the present invention.
