Description

Technical Field

[0002] like Figure 6 As shown, the tower crane is a specialized piece of equipment for dam concrete pouring construction. It consists of a cylindrical tower crane and belt conveyors. The main structure of the cylindrical tower crane includes a tower column, support platform, slewing platform, working arm, counterweight arm, and A-frame self-lifting mechanism. The belt conveyors include one aluminum alloy material transfer belt conveyor and two articulated truss conveyors. The material transfer conveyor is installed on the platform formed by the climbing frame. One end of the material transfer conveyor is articulated to the feeding belt conveyor via a drop hopper, and the other end is rotatably connected to the inner conveyor via a drop hopper. In actual operation, the height of the feed belt conveyor or internal conveyor increases continuously as the dam concrete pouring process progresses, so the height of the platform formed by the climbing frame also needs to be adjusted and raised. Traditional tower crane equipment also has similar climbing mechanisms, such as raising the crane by means of hoisting ropes or climbing cylinders, but these are for adjusting the height of the main boom. For tower belt conveyors, which are special equipment for dam concrete pouring, there is relatively little publicly available literature. Therefore, how to enable the climbing frame to climb the tower of the tower belt conveyor efficiently and stably is an urgent problem to be solved. Summary of the Invention

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-5 As shown, a tower conveyor hoisting and climbing frame equipped with a pulley system includes a truss structure 2 fitted onto the surface of a tower 1. A pin mechanism 3 is provided between the truss structure 2 and the surface of the tower 1 to lock the truss structure 2 onto the surface of the tower 1. A winch 4 and a lower fixed pulley 5 are mounted on the truss structure 2, and an upper fixed pulley 6 is mounted on the surface of the tower 1. The traction rope 4.1 of the winch 4 passes sequentially around the lower fixed pulley 5 and the upper fixed pulley 6 and connects to the truss structure 2. With this design, after the winch 4 operates, the traction rope 4.1 ultimately pulls the truss structure 2 upward. Furthermore, this pulley system structure is stable; through the limiting action of the lower fixed pulley 5 and the upper fixed pulley 6, the traction rope 4.1 can stably pull the truss structure 2 upward.

[0023] Preferably, such as Figure 2 As shown, the winch 4 includes a winch drive motor 4.2 fixedly mounted on the truss structure 2. The output shaft of the winch drive motor 4.2 is connected to the input shaft of the winch drum 4.3, and a traction rope 4.1 is wound around the surface of the winch drum 4.3. In this embodiment, when the winch drive motor 4.2 is working, it drives the winch drum 4.2 to rotate through the output shaft, thereby causing the traction rope 4.3 to move, thus pulling the truss structure 2 below upward.

[0024] Preferably, the rotating shafts at both ends of the winch drum 4.3 are rotatably connected to the mounting frame 4.4, the mounting frame 4.4 is fixedly mounted on the truss structure 2, and the winch drive motor 4.2 is fixed to one side of the mounting frame 4.4.

[0025] Preferably, the upper fixed pulley 6 is located on the maintenance platform 7 on the side of the tower 1.

[0026] Preferably, the end of the traction rope 4.1 that connects to the truss structure 2 is provided with a rope clamp 8. The rope clamp 8 can securely connect the traction rope 4.1 to the truss structure 2, preventing it from falling off.

[0027] Preferably, the truss structure 2 includes a truss body 2.1, the top of the truss body 2.1 is provided with an upper platform 2.2, the bottom is provided with a lower platform 2.3, and a ladder 2.4 is provided between the upper platform 2.2 and the lower platform 2.3.

[0028] Preferably, the inner side of the truss structure 2 is further provided with a plurality of sliding shoes 9 that slide in contact with the surface of the tower 1. As shown in the figure, the sliding shoes 9 can stabilize the position of the truss structure 2 on the surface of the tower 1.

[0029] Preferably, the plurality of sliding shoes 9 are arranged in a circular array inside the truss structure 2. As shown in the figure, there are 3 sliding shoes 9, so that the truss structure 2 will not tilt during the upward process, and plays a role in positioning and guiding.

[0030] Preferably, the pin-connecting mechanism 3 includes a locking plate 3.1, which is fixedly connected to the side of the truss structure 2 near the tower 1. The locking plate 3.1 has a hole for inserting a locking pin. An ear plate 10 is fixedly provided on the corresponding area surface of the tower 1, and the ear plate 10 has a hole for inserting a locking pin. The locking plate 3.1 is connected to the ear plate 10 via the locking pin. In this embodiment, after each climbing distance is completed, the hole on the surface of the locking plate 3.1 overlaps with the through hole between the ear plate 10 on the surface of the tower 1. Then, a locking pin is inserted through the through hole, at which point the entire truss structure 2 is suspended on the surface of the tower 1 via the locking plate 3.1.

[0031] Preferably, there are multiple locking plates 3.1, which are arranged in a circular array on the side of the truss structure 2 near the tower 1; and there are multiple ear plates 10, which are arranged in a circular array on the corresponding area surface of the tower 1. This multi-point locking further improves safety and prevents the truss structure 2 from falling.

[0032] The working principle of this embodiment is as follows:

[0033] like Figures 1 to 5 As shown, when the winch drive motor 4.2 is working, it drives the winch drum 4.2 to rotate through the output shaft, which in turn causes the traction rope 4.3 to move, thereby pulling the lower truss structure 2 upward. After moving to the designated position, the hole on the surface of the locking plate 3.1 overlaps with the through hole of the ear plate 10 in the corresponding area on the surface of the tower 1, and the winch drive motor 4.2 stops running; then, a locking pin is inserted into the through hole, and the entire truss structure 2 is then hung on the surface of the tower 1 through the locking plate 3.1, thus completing the entire climbing process.

[0034] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
