[0002] like Figure 8 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 material distribution conveyor via a receiving hopper. In actual operation, the height of the feeding belt conveyor or the inner placing conveyor continuously increases 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 platforms, such as those raised by ropes or climbing cylinders, but these are designed 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 platform to climb the tower of the tower belt conveyor efficiently and stably, and how to connect it with the feeding belt conveyor and the inner placing conveyor, are urgent problems to be solved.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-7As shown, a tower climbing platform for a tower conveyor includes a climbing frame. The climbing frame includes a truss structure 2 fitted onto the surface of the tower 1. The truss structure 2 is hinged to one end of a telescopic device 3, and the other end of the telescopic device 3 is detachably hinged to the surface of the tower 1. A pin-locking mechanism 7 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 dropping hopper 9 is provided on one side of the climbing frame and is hinged to the conveying end of a feeding belt conveyor 8. A transfer conveyor belt 10 is provided below the dropping hopper 9, and a receiving hopper 12 is provided at the conveying end of the transfer conveyor belt 10 and is rotatably connected to the conveying front end of an inner material conveyor 11. In this embodiment, the material conveyed from the feeding belt conveyor 8 can fall into the transfer conveyor belt 10 below through the drop hopper 9, and then be conveyed to the receiving hopper 12 by the transfer conveyor belt 10, and finally enter the inner material distribution conveyor 11. Since the feeding belt conveyor 8 is also raised through its own bottom lifting platform during the climbing frame climbing process, there may be a relative rotation process between one side of the climbing frame and the conveying end of the feeding belt conveyor 8. Therefore, one side of the climbing frame needs to be hinged to the conveying end of the feeding belt conveyor 8 through the drop hopper 9. In addition, since the inner material distribution conveyor 11 will swing laterally through the hoisting mechanism above during the dam pouring process, the conveying end of the transfer conveyor belt 10 is rotatably connected to the conveying front end of the inner material distribution conveyor 11 through the receiving hopper 12.

[0027] Preferably, the telescopic device 3 is a hydraulic telescopic cylinder structure, an electric push rod structure, or a pneumatic telescopic cylinder structure. In this embodiment, if a hydraulic telescopic cylinder structure is used, a double-rod hydraulic cylinder can be selected, which can improve stability and safety.

[0028] Preferably, the truss structure 2 includes a truss body 2.1, with an upper platform 2.2 at the top and a lower platform 2.3 at the bottom. A ladder 2.4 is provided between the upper platform 2.2 and the lower platform 2.3. A material transfer conveyor belt 10 is horizontally arranged on the lower platform 2.3. A material drop hopper 9 is provided above the front end of the material transfer conveyor belt 10, and a material receiving hopper 12 is provided below the end of the material transfer conveyor belt 10. In this embodiment, the ladder 2.4 facilitates manual maintenance.

[0029] Preferably, the bottom of the inner material conveyor 11 is connected to the upper platform 2.2 via an inner suspension wire rope mechanism 13, and the conveying front end of the inner material conveyor 11 is hinged to the bottom of the truss body 2.1. In this embodiment, the inner suspension wire rope mechanism 13 can limit the vertical movement of the inner material conveyor 11, and the angle of the inner material conveyor 11 in the vertical direction, i.e., the pitch angle, can be adjusted by the inner suspension wire rope mechanism 13 to adapt to the specific pouring site.

[0030] Preferably, such as Figure 4 and 5As shown, the end of the telescopic device 3 is connected to the reinforcing rod 3.2 via a connecting plate 3.1. The connecting plate 3.1, the reinforcing rod 3.2, and the surface of the tower 1 are all provided with through holes 4 for inserting limiting pins. In this embodiment, since both the connecting plate 3.1 and the reinforcing rod 3.2 have through holes 4, two sets of limiting pins can be inserted, providing an extra layer of safety and improving the security of the limiting mechanism.

[0031] Preferably, an ear plate 5 is fixedly provided on the surface of the tower 1, and a through hole 4 for inserting a limiting pin is formed on the surface of the ear plate 5. In this embodiment, by fixing the ear plate 5 on the surface of the tower 1, the direct drilling of holes on the surface of the tower 1 is avoided, which facilitates construction and will not damage the main structure of the tower 1.

[0032] In this embodiment, the telescopic device 3 may include the following two implementation methods:

[0033] Example 1: The top end of the telescopic device 3 is detachably hinged to the surface of the tower 1, and the bottom end is hinged to the truss structure 2. In this case, the telescopic device 3 raises the truss structure 2 by pulling. With this design, the truss structure 2 can be raised each time the telescopic device 3 retracts.

[0034] Example 2: Figure 4 and 5 As shown, the bottom end of the telescopic device 3 is detachably hinged to the surface of the tower 1, and the top end is hinged to the truss structure 2. In this case, the telescopic device 3 raises the truss structure 2 by jacking it up. With this design, the telescopic device 3 can jack up the truss structure 2 each time it extends.

[0035] Preferably, such as Figure 6 As shown, the inner side of the truss structure 2 is also provided with multiple sliding shoes 6 that slide in contact with the surface of the tower 1. Figure 5 As shown, the sliding shoe 6 can stabilize the position of the truss structure 2 on the surface of the tower 1; more preferably, as shown in the figure, there are 3 sliding shoes 6, so that the truss structure 2 will not tilt during the rising process, and plays a role in positioning and guiding.

[0036] Preferably, there are multiple telescopic devices 3, which are arranged in a circular array along the circumference of the tower 1. More preferably, there are three telescopic devices 3, so that the forces exerted by the telescopic devices 3 on the truss structure 2 as a whole are balanced during the telescopic process.

[0037] Preferably, such as Figure 7As shown, the pin-operated mechanism 7 includes a locking plate 7.1, which is fixedly connected to the side of the truss structure 2 near the tower 1. The locking plate 7.1 has a hole for inserting a locking pin. A lug plate 5 is also fixedly provided on the surface of the corresponding area of ​​the tower 1. The lug plate 5 also has a hole for inserting a locking pin. The locking plate 7.1 is connected to the lug plate 5 via the locking pin. In this embodiment, after each climbing process of a certain distance, the hole on the surface of the locking plate 7.1 overlaps with the through hole 4 between the lug plate 5 on the surface of the tower 1. Then, a locking pin is inserted through the through hole 4, and the limiting pin inserted at the lower end of the telescopic device 3 and the corresponding lug plate 5 on the surface of the tower 1 is pulled out. At this time, the entire truss structure 2 is hung on the surface of the tower 1 via the locking plate 7.1.

[0038] Preferably, there are multiple locking plates 7.1, arranged in a circular array on the side of the truss structure 2 closest to the tower 1; and there are multiple ear plates 5, 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.

[0039] The working principle of this embodiment is as follows:

[0040] Taking Example 2 as an example, such as Figure 4 and 5 As shown, in this embodiment, the telescopic device 3 adopts a hydraulic telescopic cylinder structure. The bottom end of the telescopic device 3 is detachably hinged to the surface of the tower 1, and the top end is hinged to the truss structure 2. At this time, the telescopic device 3 raises the truss structure 2 by lifting. During the climbing process, the telescopic device 3 first extends, thereby applying a thrust to the upper platform 2.2, causing the entire truss structure 2 to move upward. After completing a certain distance of climbing, the hole on the surface of the locking plate 7.1 overlaps with the through hole 4 between the corresponding area of ​​the ear plate 5 on the surface of the tower 1, and the winch drive motor 4.1 also stops running. Then, a locking pin is inserted through the through hole 4, and the limiting pin inserted at the lower end of the telescopic device 3 and the corresponding ear plate 5 on the surface of the tower 1 is pulled out. At this time, the entire truss structure 2 is lifted by the upper locking pin. The fixed plate 2.1 is hung on the surface of the tower 1; then the telescopic device 3 retracts, causing the lower end of the telescopic device 3 to move upward. After moving upward a certain distance, the through hole 4 between the lower end of the telescopic device 3 and the ear plate 5 on the surface of the tower 1 overlaps with each other. Then, the limiting pin is re-inserted into the through hole 4, and the locking pin inserted into the upper truss structure 2 and the corresponding ear plate 5 on the surface of the tower 1 is pulled out. At this time, the next climbing process can begin. Repeat the above continuous alternating climbing process, and finally the climbing frame can be climbed on the surface of the tower. During the material conveying process, the material conveyed from the feeding belt conveyor 8 can fall into the lower transfer conveyor belt 10 through the dropping hopper 9, and then be conveyed to the receiving hopper 12 through the transfer conveyor belt 10, and finally enter the inner material distribution conveyor 11.

[0041] In addition, the locking pin insertion process in this embodiment can be carried out manually as described above, or the insertion cylinder can be installed horizontally to control the automatic insertion process.

[0042] 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.
