Aiming at the onshore wind power hoisting difficulty of more than 150 meters in the existing market, a large wind power hoisting tower crane is provided. As the height increases, self-jacking mechanisms of tower cranes have evolved into different forms, but all jacking mechanisms include this part of the climbing nest. In order to prevent standard joints from deflecting, a guide device is designed in the sleeve frame. At present, a guide roller is widely applied to the market, and the roller rolls on the standard knot according to all directions to play a role in guiding, but the size of the connecting position of the standard knot is limited, and if the connecting position is large, such as a flange, the roller cannot be used for guiding. The sliding rails are welded on part of the sleeve frame, the sliding blocks are welded on the standard joints, the tips of the sliding blocks and the tips of the flange plates are positioned on the same straight line, and the gaps between the sliding rails and the sliding blocks are controlled to play a guiding role. However, this form cannot be adjusted, and is liable to cause wear of the slide rail of the stock, and only the truss pieces of the whole stock can be replaced, which results in high maintenance cost.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to enable those skilled in the art to better understand the scheme of the present application, the present application will be described in further detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 and fig. 2, fig. 1 is a partial schematic view of a tower crane climbing frame provided by an embodiment of the present application, and fig. 2 is a schematic view of an assembly of a wear-resistant gasket and a slide rail in fig. 1.

The embodiment of the application provides a tower machine cover frame that climbs, this cover frame that climbs includes cover frame body 1, slide rail 2 and wear-resisting gasket 4, the inboard vertical slide rail 2 that sets up to the lift direction of standard festival of cover frame body 1, because slide rail 2 welds with cover frame body 1 an organic whole usually, to avoid terminal and the slider wearing and tearing slide rail 2 of flange of standard festival to lead to cover frame body 1 to scrap, this application sets up a plurality of fixed orificess on slide rail 2 very much, and set up wear-resisting gasket 4 on the surface of slide rail 2, wear-resisting gasket 4 is fixed on slide rail 2 surface through fasteners such as countersunk screw 5 and fixed orifices cooperation, with the help of the distance of wear-resisting gasket 4 control and slider and utilize wear-resisting gasket 4 and flange and slider contact friction. After the wear-resistant gasket 4 is worn, only the wear-resistant gasket 4 needs to be replaced, and the sleeve frame body 1 does not need to be integrally replaced, so that the maintenance cost of the tower crane climbing sleeve frame is remarkably reduced.

In an embodiment, the wear-resistant pad 4 is specifically a nylon pad, the shape of the nylon pad is matched with that of the guide rail, the cross section of the nylon pad is in an L shape, and the whole wear-resistant pad is similar to that of the angle iron. In specific implementation, the wear-resistant pad 4 is not limited to a nylon pad, and a pad with a buffering effect made of rubber or other materials may be used. For the convenient shaping of wear-resisting gasket 4, wear-resisting gasket 4 segmentation sets up, and same slide rail 2 is fixed along length direction sets up multiunit wear-resisting gasket 4, and the end to end of upper and lower adjacent gasket is the butt in proper order, still can bond at the butt terminal surface rubber coating of adjacent gasket as required.

In an embodiment, in order to facilitate installation of the wear-resistant gasket 4 and reduce interference of the fastener 5 on lifting of the standard knot, the wear-resistant gasket 4 is provided with a stepped counter bore corresponding to a fixed hole on the slide rail 2, one end of the fastener 5 is fixedly connected with the slide rail 2 through threads, and the head of the fastener 5 is attached to a stepped surface of the stepped counter bore, so that the head of the fastener 5 is completely located in the stepped counter bore, and the head of the fastener 5 is prevented from being exposed out of the wear-resistant gasket 4 and colliding with a sliding block or a flange of the standard knot.

On the basis of the above embodiment, the tower crane climbing stock provided by the embodiment of the application further comprises an adjusting gasket 3, as shown in fig. 2, the adjusting gasket 3 is arranged between the surface of the sliding rail 2 and the wear-resistant gasket 4, and the adjusting gasket 3 and the wear-resistant gasket 4 are matched to adjust the distance between the sliding block and the flange of the standard knot and the sliding rail 2, so that the design requirement that the distance between the standard knot and the sliding rail 2 of the stock body 1 is maintained at 4mm is met. When the wear-resistant pads 4 are arranged in sections, the adjusting pads 3 can be arranged at one end with the same length as the slide rail 2, and can also be designed with the same length as the wear-resistant pads 4, because the wear-resistant pads 4 and the slide rail 2 have two binding surfaces, each group of slide rails 2 and each group of wear-resistant pads 4 usually correspond to two groups of adjusting pads 3.
