Technical Field

The invention relates to a safety rope tying and hanging protection device for the walking of a large arm of a tower crane.

Background

In the process of installing, dismantling and maintaining the large arm of the tower crane, personnel must walk back and forth on the large arm according to the working requirement. However, the large arm of the tower crane is made of a steel structure, the main chord members are connected in a multi-position steel structure, the safety belt needs to be continuously tied and hung when an operator walks on the large arm of the tower crane due to the fact that the distance between the diagonal bracing connecting rods is too short (the maximum distance is not more than 50cm), the safety belt needs to be tied and hung again every two or three steps basically, work is not facilitated, and the safety belt is not used at all because some operators wear the safety belt due to trouble in the walking process of the large arm of the tower crane, and great safety risk exists; meanwhile, the accident caused by unbalance due to the fact that the safety belt is pulled because the safety belt is sometimes forgotten to be loosened during the work is also considered.

Disclosure of Invention

The invention aims to solve the technical problem of providing a safety rope tying and hanging protection device for the large arm walking of a tower crane, which has a reasonable structure and is convenient to use.

In order to solve the technical problem, the invention provides a safety rope tying and hanging protection device for the large arm walking of a tower crane;

comprises a safety rope, a fixing component and a hook component;

the fixing component at least comprises two fixing rings, the two fixing rings are respectively and fixedly connected with the two sides of the large arm of the tower crane, and the two ends of the safety rope are respectively and fixedly connected with the two fixing rings of the fixing component;

the hook component comprises a plurality of hook seats, the hook seats are fixedly connected to the tower crane large arm and located between two fixing rings of the fixing component, the hook seats are distributed at intervals in sequence, the distribution trend of the hook seats is consistent with the length direction of the safety rope, the hook seats are provided with hooking grooves, the hooking grooves penetrate through two sides of the hook seats, and the hooking grooves of the hook seats are matched with the safety rope.

In order to more clearly understand the technical content of the invention, the protection device for tying the safety rope for the walking of the large arm of the tower crane is simply referred to as the protection device below.

Preferably, the hook base is provided with a guide channel, the guide channel also penetrates through two sides of the hook bases on two sides, the safety rope enters and exits the hook holding groove through the guide channel, and an opening of the guide channel is positioned on the end face of the hook base, which is close to one side of the tower crane boom; with this arrangement, the guide passage can define a path for the safety line to enter and exit the hooking groove.

As the optimization of this protection device, guide channel top opening is on the terminal surface that the couple seat is close to tower crane large arm one side, guide channel middle part is equipped with downwards and bends, guide channel end and hook hold the groove intercommunication.

Preferably, the guide channel is provided with at least one blocking protrusion on one side wall in the middle.

Preferably, the safety rope is a steel wire rope.

As the optimization of this protection device, fixed subassembly still includes a plurality of wire rope buckles, and a plurality of wire rope buckles divide into two sets ofly, two sets of wire rope buckles and two retainer plates one-to-one, and safety rope tip runs through behind the corresponding retainer plate and fixes through a set of wire rope buckle.

After adopting such structure, installation and maintenance personnel hang the safety belt on the safety rope in the walking process on the tower crane jib, and the inspection of walking back and forth is convenient to ensure the safety of operating personnel.

In addition, because the large arm of the tower crane is long, if the end position of the safety rope is limited only by the fixing component, when the installation and maintenance personnel walk to the middle part of the large arm of the tower crane, the safety rope is stressed and can be stretched and deformed, and stable support cannot be provided for the installation and maintenance personnel;

if a plurality of segment fixing points are arranged between two fixing rings of the fixing component, although the purpose of stabilizing the safety rope can be achieved, installation and maintenance personnel have to remove the connecting lock catches between the segment fixing points and the safety rope each time when the installation and maintenance personnel pass through the segment fixing points, and then quickly cross the segment fixing points and then reconnect the segment fixing points.

A plurality of segmentation fixed points between two retainer plates are replaced to a plurality of couple seats through the couple subassembly in this application, installation and dimension guarantor personnel when certain couple seat, break away from the cooperation with the couple seat earlier safety rope, need not stride across the couple seat under the prerequisite of connecting lock catch and safety rope separation, stride across behind the couple seat again with safety rope and couple seat cooperation, installation and dimension guarantor personnel's connecting lock catch is fixed all the time on safety rope, the safety risk that significantly reduces.

The beneficial technical effect of this protection device does: the safety coefficient of the personnel of maintaining of ann's tearing open during the big arm walking of equipment fixing and inspection dimension guarantor process is greatly improved, alleviate the fear in walking process high altitude simultaneously. The construction efficiency is improved while the personal safety is further ensured.
