[0002] like Figure 7 As shown, the tower crane, a specialized piece of equipment for dam concrete pouring construction, is a combination of a cylindrical tower crane and a belt conveyor. The main components of the cylindrical tower crane include the tower column, support platform, slewing platform, working boom, counterweight boom, and A-frame self-lifting mechanism. The belt conveyor consists of one aluminum alloy material transfer belt conveyor and two articulated truss conveyors.

[0003] A material transfer conveyor is installed on a platform constructed using a climbing frame. One end of the conveyor is hinged to the feed belt conveyor via a hopper, while the other end is rotatably connected to the inner conveyor via the hopper. During the actual dam concrete pouring process, the height of the feed belt conveyor or inner conveyor will continuously increase with construction, requiring the platform height formed by the climbing frame to be adjusted and raised accordingly.

[0004] While traditional tower cranes possess similar climbing mechanisms, such as using ropes or hydraulic cylinders for elevation, these primarily address adjustments to the boom's height. However, for tower belt conveyors, specialized equipment for dam concrete pouring, publicly available documentation is scarce. Therefore, ensuring efficient and stable climbing of the climbing frame on the tower belt conveyor's tower section presents a critical challenge. Furthermore, the design of the climbing mechanism must consider its integration with both the material supply belt conveyor and the internal material placing conveyor, a crucial aspect that cannot be overlooked during the design process.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 6 As shown, a manually locked double-layer climbing sleeve for a tower conveyor includes a climbing sleeve 2 fitted onto the surface of the tower 1. The climbing sleeve 2 is an annular cavity structure composed of a double-layer ring cylinder. One end of the climbing sleeve 2 is hinged to a telescopic device 3, and the other end of the telescopic device 3 is detachably hinged to the surface of the tower 1. The climbing sleeve 2 is provided with a manual pin-locking mechanism 7 for locking the climbing sleeve 2 onto the surface of the tower 1.

[0030] In this utility model, since the climbing sleeve 2 is an annular cavity structure composed of a double-layered annular cylinder, it can also perform a part of the feeding function. Specifically, there are the following two implementation methods:

[0031] Implementation method 1: such as Figure 2As shown, the annular cavity of the climbing sleeve 2 is provided with a closed feeding channel 2.9. The feeding channel 2.9 has an inlet 2.1 at the top or side and an outlet 2.2 at the bottom. The inlet 2.1 is connected to the end of the feeding belt conveyor, and a transfer conveyor belt is provided below the outlet 2.2. In this embodiment, two partitions can be vertically arranged in the annular cavity to form a closed feeding channel 2.9. When material comes from the feeding belt conveyor, it can directly enter the feeding channel 2.9 in the annular cavity through the inlet 2.1, and then exit from the outlet 2.2 below, falling into the transfer conveyor below, and then being transported by the transfer conveyor to the inner material distribution conveyor.

[0032] Implementation method 2: such as Figure 3 As shown, the annular cavity of the climbing sleeve 2 is provided with a feeding cylinder 2.10. The feeding cylinder 2.10 has a feeding port 2.1 at the top or side and a discharging port 2.2 at the bottom. The feeding port 2.1 is connected to the end of the feeding belt conveyor, and a transfer conveyor belt is provided below the discharging port 2.2. In this embodiment, the feeding cylinder 2.10 can be fixedly installed separately in the annular cavity. When material comes from the feeding belt conveyor, it can directly enter the feeding cylinder 2.10 in the annular cavity through the feeding port 2.1, and then exit from the discharging port 2.2 below, falling into the transfer conveyor below, and then being transported by the transfer conveyor to the inner material distribution conveyor.

[0033] In both of the above embodiments, a receiving hopper is also provided at the feed inlet 2.1. The receiving hopper is connected to the end of the feeding belt conveyor, thereby connecting the end of the feeding belt conveyor to the feed inlet 2.1.

[0034] 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.

[0035] Preferably, such as Figure 2 and 3 As shown, the climbing sleeve 2 includes an outer annular cylinder 2.3 and an inner annular cylinder 2.4. The inner ring of the inner annular cylinder 2.4 is slidably fitted with the surface of the tower cylinder 1. A connecting rod 2.5 for fixing the two is provided in the interlayer gap between the outer annular cylinder 2.3 and the inner annular cylinder 2.4.

[0036] Preferably, the climbing sleeve 2 has an upper platform 2.6 at the top and a lower platform 2.7 at the bottom, with a ladder 2.8 between the upper platform 2.6 and the lower platform 2.7. In this embodiment, the ladder 2.8 facilitates manual maintenance. In this embodiment, the feed inlet 2.1 is located inside the upper platform 2.1, and the discharge hopper is also easily installed on the upper platform 2.1; the discharge outlet is located inside the lower platform 2.2, and the receiving hopper is also easily installed on the lower platform 2.2.

[0037] Preferably, such as Figure 4 and 5 As shown, the other 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 the connecting plate 3.1 and the reinforcing rod 3.2 are both provided with through holes 4, two sets of limiting pins can be inserted, providing an extra layer of protection and improving the safety of the limiting mechanism.

[0038] 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.

[0039] In this embodiment, the telescopic device 3 may include the following two implementation methods:

[0040] 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 climbing sleeve 2. In this case, the telescopic device 3 raises the climbing sleeve 2 by pulling. With this design, the climbing sleeve 2 can be raised each time the telescopic device 3 retracts.

[0041] Example 2: As 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 climbing sleeve 2. In this case, the telescopic device 3 raises the climbing sleeve 2 by jacking it up. With this design, the telescopic device 3 can lift the climbing sleeve 2 each time it extends.

[0042] Preferably, such as Figure 2 As shown, the inner side of the climbing sleeve 2 is also provided with multiple sliding shoes 6 that slide in contact with the surface of the tower 1. The sliding shoes 6 can stabilize the position of the climbing sleeve 2 on the surface of the tower 1; more preferably, as shown in the figure, there are 3 sliding shoes 6, so that the climbing sleeve 2 will not tilt during the ascent, and plays a role in positioning and guiding.

[0043] 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 climbing sleeve 2 as a whole are balanced during the telescopic process.

[0044] Preferably, such as Figure 2 As shown, the manual pin-threading mechanism 7 includes a locking plate 7.1, which is fixedly connected to the side of the climbing sleeve 2 near the tower 1. The locking plate 7.1 has a hole for inserting a locking pin. A corresponding ear plate 5 is also fixedly provided on the surface of the corresponding area of ​​the tower 1. The ear plate 5 also has a hole for inserting a locking pin. The locking plate 7.1 is connected to the ear 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 ear 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 ear plate 5 on the surface of the tower 1 is pulled out. At this time, the entire climbing sleeve 2 is hung on the surface of the tower 1 via the locking plate 7.1.

[0045] Preferably, there are multiple locking plates 7.1 arranged in a circular array on the side of the climbing sleeve 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 climbing sleeve 2 from falling.

[0046] The working principle of this embodiment is as follows:

[0047] like Figures 1 to 5 As shown, the telescopic device 3 in this embodiment adopts a hydraulic telescopic cylinder structure, which is the same structure as in embodiment 2. In addition, the upper end of the telescopic device 3 is hinged to the lower platform 2.6 of the climbing sleeve 2, and the other end is detachably hinged to the ear plate 5 fixedly installed on the surface of the tower 1. During the climbing process, the telescopic device 3 first extends, thereby applying a thrust to the lower platform 2.6, causing the entire climbing sleeve 2 to move upward. After completing a certain distance of climbing process, the hole on the surface of the locking plate 7.1 overlaps with the through hole 4 between the ear plate 5 on the surface of the tower 1. Then, a locking pin is inserted through the through hole 4. Then, 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 climbing sleeve 2 is hung on the surface of the tower 1 through the locking plate 7.1. 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 between the upper climbing sleeve 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. By repeating the above continuous alternating climbing process, the climbing sleeve 2 can eventually climb on the surface of the tower.

[0048] In addition, in this embodiment, since the climbing sleeve 2 is an annular cavity structure composed of a double-layered annular cylinder, it can also serve as a material feeding function. When material comes from the feeding belt conveyor, it can directly enter the material discharge channel or material discharge cylinder inside the annular cavity structure of the climbing sleeve 2 from the inlet 2.1, and then exit from the outlet 2.2 below, falling into the transfer conveyor below, and then being transported by the transfer conveyor to the inner material distribution conveyor.

[0049] 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.
