Technical Field

[0001] The utility model relates to the field of cable - type hoisting construction, and specifically relates to a sheave and a rope hanging system for a towing rope and a lifting rope of a cable - type crane. Background Technique

[0002] Cable - type cranes are widely used in bridge hoisting construction due to their strong adaptability and spanning ability. The carriage can travel on the load - bearing rope at the mid - span. The horizontal movement of the trolley is realized by controlling the towing rope, and the vertical movement of the spreader is realized by controlling the lifting rope.

[0003] In the existing layout of cable - type cranes, the towing rope and the lifting rope at the side - span are often in a freely - suspended state, and their sag and tension are not effectively controlled, resulting in a greater impact on the construction of mechanical equipment below. Moreover, a large counterweight is required on the spreader to ensure the smooth lowering of the spreader when it is unloaded and to avoid hitting the top. Content of the Utility Model

[0004] Therefore, to solve the above - mentioned deficiencies, the utility model provides a sheave and a rope hanging system for a towing rope and a lifting rope of a cable - type crane here. The tension of the towing rope and the lifting rope is reduced, thereby reducing the counterweight required during the construction of the spreader at the mid - span. At the same time, the sag of the towing rope and the lifting rope at the side - span is reduced, increasing the activity space of mechanical equipment such as gantry cranes at the side - span.

[0005] The utility model is realized as follows. A sheave (5) for a towing rope and a lifting rope of a cable - type crane is constructed. Its characteristics are as follows: The sheave (5) consists of splint A (8 - 1), splint B (8 - 2), rollers (9) and a connecting shaft (10). There are two groups of rollers (9). The towing rope or the lifting rope (4) passes through between the two groups of rollers (9). Splint A (8 - 1) and splint B (8 - 2) are connected as a whole through the connecting shaft (10).

[0006] A rope hanging system, its characteristics are as follows: A load - bearing rope (3) is arranged at the side - span, one end is fixed to the top of the main tower (1), and the other end is fixed to a suitable position around the anchor block (2). A sheave (5) is installed on the load - bearing rope (3) to hold the towing rope or the lifting rope (4). The sheave (5) consists of splint A (8 - 1), splint B (8 - 2), rollers (9) and a connecting shaft (10). There are two groups of rollers (9). The towing rope or the lifting rope (4) passes through between the two groups of rollers (9). Splint A (8 - 1) and splint B (8 - 2) are connected as a whole through the connecting shaft (10). The two groups of rollers (9) are located between splint A (8 - 1) and splint B (8 - 2). The upper end of the sheave (5) is fixed to the load - bearing rope (3) by a connecting rope (7) through a rope clip (6).

[0007] The utility model has the following advantages: In this application, a load-bearing rope is arranged at the side span, one end is fixed to the top of the main tower, and the other end is fixed to a suitable position around the anchor. A sheave is installed on the steel rope to hold the towing rope and the lifting rope. Through the implementation of this application, the tension of the towing rope and the lifting rope is reduced, thereby reducing the counterweight required during the construction of the sling at the mid-span; at the same time, the sag of the towing rope and the lifting rope at the side span is reduced, increasing the activity space of mechanical equipment such as gantry cranes at the side span.
