Technical Field

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 drop hopper. In actual operation, the height of the feeding belt conveyor or inner 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 mechanisms, such as raising the crane by means of hoisting ropes or climbing cylinders; however, 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 mechanism to climb the tower of the tower belt conveyor efficiently and stably is an urgent problem to be solved. Furthermore, the climbing mechanism also needs to be connected to both the feeding belt conveyor and the inner conveyor, and this issue needs to be considered in the design. Summary of the Invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0028] like Figure 1-6 As shown, an automatically locking 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 body. 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 an automatic pin-locking mechanism 7 for locking the climbing sleeve 2 onto the surface of the tower 1.
[0029] 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:
[0030] Implementation method 1: such as Figure 2 As 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] Preferably, 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 for fixing the two is provided in the interlayer gap between the outer annular cylinder 2.3 and the inner annular cylinder 2.4.
[0035] Preferably, the climbing sleeve 2 has an upper platform 2.5 at the top and a lower platform 2.6 at the bottom, with a ladder 2.7 between the upper platform 2.5 and the lower platform 2.6. In this embodiment, the ladder 2.7 facilitates manual maintenance. In this embodiment, the feed inlet 2.1 is located inside the upper platform 2.5, and the discharge hopper is also easily installed on the upper platform 2.5; the discharge outlet is located inside the lower platform 2.6, and the receiving hopper is also easily installed on the lower platform 2.6.
[0036] 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.
[0037] 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.
[0038] In this embodiment, the telescopic device 3 may include the following two implementation methods:
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] Preferably, such as Figure 6 As shown, the automatic pin-threading mechanism 7 includes a mounting plate 7.1 fixedly mounted on the climbing sleeve 2 (for ease of installation, in this embodiment, the mounting plate 7.1 is located within an upper platform 2.5 at the top of the climbing sleeve 2). A pin-threading cylinder 7.2 is horizontally fixed on the mounting plate 7.1. Pin-threading holes 7.3, which cooperate with the telescopic rod of the pin-threading cylinder 7.2, are opened on the corresponding areas of the climbing sleeve 2 and the tower cylinder 1. In this embodiment, after each climbing process of a certain distance, the telescopic rod of the pin-threading cylinder 7.2 aligns with the pin-threading hole 7.3 on the surface of the tower cylinder 1. Then, after the pin-threading cylinder 7.2 operates, its telescopic rod extends and enters the pin-threading hole 7.3. Then, the limiting pin inserted into the ear plate 5 corresponding to the lower end of the telescopic device 3 and the surface of the tower cylinder 1 is pulled out. At this time, the entire climbing sleeve 2 is hung on the surface of the tower cylinder 1 through the pin-threading cylinder 7.2. More preferably, the pin-threading cylinder 7.2 is a pin-threading hydraulic cylinder or a pin-threading pneumatic cylinder with a telescopic rod structure.
[0044] Preferably, the mounting plate 7.1 has a ring structure, and the number of pin-piercing cylinders 7.2 is multiple and distributed in a ring array on the mounting plate 7.1. This multi-point locking further improves safety and prevents the climbing sleeve 2 from falling.
[0045] The working principle of this embodiment is as follows:
[0046] like Figures 1 to 6As shown, the telescopic device 3 in this embodiment adopts a hydraulic telescopic cylinder structure, which is the same structure as in embodiment 2. Furthermore, 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, the telescopic rod of the pin-piercing cylinder 7.2 aligns with the pin-piercing hole 7.3 on the surface of the tower 1. Then, after the pin-piercing cylinder 7.2 operates, its telescopic rod extends and enters the pin-piercing hole 7.3, and then the limiting pin inserted through the ear plate 5 corresponding to the lower end of the telescopic device 3 on the surface of the tower 1 is pulled out. At this time, the entire climbing sleeve 2 is hung on the tower 1 by the pin-piercing cylinder 7.2. The surface; 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 lower end of the telescopic device 3 overlaps with the through hole 4 between the ear plate 5 on the surface of the tower 1. Then, the limiting pin is re-inserted through the through hole 4, and the telescopic rod of the upper pin-inserting cylinder 7.2 retracts, so that the telescopic rod leaves the pin-inserting hole 7.3 and the locking state is released. At this time, the next climbing process can begin. Repeat the above continuous alternating climbing process, and finally the climbing sleeve can be climbed on the surface of the tower.
[0047] 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.
[0048] 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.
