Description

Technical Field

[0001] This utility model relates to the field of tower belt conveyor technology, and in particular to a tower belt conveyor climbing sleeve with a spiral groove. Background Technology

[0002] like Figure 7 As shown, the tower crane, as a core specialized equipment for dam concrete pouring construction, is structurally composed of a cylindrical tower crane and a belt conveyor. The cylindrical tower crane integrates key components such as the tower column, support platform, slewing platform, working boom, counterweight boom, and A-frame self-lifting mechanism. The belt conveyor is equipped with one aluminum alloy material transfer belt conveyor and two articulated truss conveyors, working together to achieve efficient concrete transportation.

[0003] On the working platform constructed by the climbing frame, the material transfer conveyor plays a crucial role in material transfer. One end of it is hinged to the feeding belt conveyor via a drop hopper, forming a flexible material transfer interface. The other end, also using the drop hopper as a hub, is rotatably connected to the inner conveyor, ensuring a smooth connection in the concrete conveying process. As the dam concrete pouring operation continues, the height of the feeding belt conveyor and the inner conveyor needs to be increased synchronously, which requires the climbing frame platform to achieve precise and dynamic height adjustment.

[0004] Compared to traditional tower cranes that use rope traction or hydraulic cylinders to drive the boom lifting mechanism, tower belt conveyors have more unique climbing requirements. Because they need to be compatible with the overall height of the concrete conveying system, and because publicly available technical information is scarce, designing a climbing mechanism that ensures efficient and stable operation of the climbing frame on the tower while also properly addressing the connection issues with the feeding belt conveyor and the internal placing conveyor has become a dual technical bottleneck that urgently needs to be overcome in the current research and development of tower belt conveyor technology. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a tower belt conveyor climbing sleeve with a spiral groove, which can realize the climbing process of the tower belt conveyor tower in a high-efficiency and stable manner, and can be well connected with the feeding belt conveyor and the inner material conveyor.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a climbing sleeve for a tower conveyor with a spiral groove, comprising a climbing sleeve sleeved on the surface of the tower, wherein a spiral groove is wound around the outer surface of the climbing sleeve from top to bottom, the top of the spiral groove is a feed inlet and the bottom is a discharge outlet, the feed inlet is matched with the end of the feeding belt conveyor, the discharge outlet is matched with the front end of the inner material conveyor, one end of the climbing sleeve is hinged to a telescopic device, the other end of the telescopic device is detachably hinged to the surface of the tower, and a manual pin-locking mechanism is provided between the climbing sleeve and the surface of the tower for locking the climbing sleeve to the surface of the tower.

[0011] Preferably, the top end of the telescopic device is detachably hinged to the surface of the tower, and the bottom end is hinged to the climbing sleeve. In this case, the telescopic device causes the climbing sleeve to rise by pulling.

[0012] Preferably, the bottom end of the telescopic device is detachably hinged to the surface of the tower, and the top end is hinged to the climbing sleeve. In this case, the telescopic device raises the climbing sleeve by jacking.

[0013] Preferably, the inner side of the climbing sleeve is also provided with a plurality of sliding shoes that slide in cooperation with the surface of the tower.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-6As shown, a tower conveyor climbing sleeve with a spiral groove includes a climbing sleeve 2 sleeved on the surface of the tower 1. The outer surface of the climbing sleeve 2 is provided with a spiral groove 8 from top to bottom. The top of the spiral groove 8 is a feed inlet and the bottom is a discharge outlet. The feed inlet is connected to the end of the feeding belt conveyor, and the discharge outlet is connected to the front end of the inner material conveyor. The climbing sleeve 2 is hinged to one end of the telescopic device 3, and the other end of the telescopic device 3 is detachably hinged to the surface of the tower 1. A manual pin-locking mechanism 7 is provided between the climbing sleeve 2 and the surface of the tower 1 for locking the climbing sleeve 2 to the surface of the tower 1. In traditional climbing frame platforms, materials conveyed from the feeding belt conveyor need to first fall through the hopper into the transfer conveyor below, and then be conveyed by the transfer conveyor to the receiving hopper, and finally enter the inner material distribution conveyor. However, in this embodiment, due to the spiral conveying function of the spiral chute 8, the material can be directly transferred from the top side of the outer surface of the climbing sleeve 2 to the bottom side of the outer surface of the climbing sleeve 2. In other words, the material from the end of the feeding belt conveyor can be directly transferred to the front end of the inner material distribution conveyor, thus eliminating the need for a transfer conveyor and simplifying the structure of the entire climbing platform.

[0029] 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.

[0030] Preferably, the climbing sleeve 2 has an upper platform 2.1 at the top and a lower platform 2.2 at the bottom, and a ladder 2.3 is provided between the upper platform 2.1 and the lower platform 2.2. In this embodiment, the ladder 2.3 facilitates manual maintenance.

[0031] Preferably, 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.

[0032] 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.

[0033] In this embodiment, the telescopic device 3 may include the following two implementation methods:

[0034] 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.

[0035] Example 2: As Figure 5 and 6 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.

[0036] Preferably, such as Figure 3 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.

[0037] 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.

[0038] Preferably, such as Figure 3 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.

[0039] 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.

[0040] Preferably, such as Figure 4As shown, a limiting sleeve 9 is also fixedly fitted on the outer side of the spiral groove 8. In this embodiment, in order to prevent material from spilling from the outer side of the spiral groove 8, a limiting sleeve 11 can be fixedly fitted on the outer side of the spiral groove 8, so that the material will not spill from the outer side of the spiral groove 8.

[0041] Preferably, the feed inlet at the top of the spiral chute 8 is provided with a drop hopper hinged to the end of the feeding belt conveyor, and the discharge outlet at the bottom of the spiral chute 8 is provided with a receiving hopper rotatably connected to the front end of the inner fabric conveyor (in this embodiment, the feed inlet at the top of the spiral chute 8 is located inside the upper platform 2.1, and the drop hopper is also conveniently installed on the upper platform 2.1; the discharge outlet at the bottom of the spiral chute 8 is located inside the lower platform 2.2, and the receiving hopper is also conveniently installed on the lower platform 2.2). During the climbing process of the climbing sleeve 2, the feeding belt conveyor also rises through its own bottom lifting platform. Therefore, there may be a relative rotation process between one side of the climbing sleeve 2 and the end of the feeding belt conveyor. Thus, the top inlet of the spiral chute 8 on one side of the climbing sleeve 2 needs to be hinged to the end of the feeding belt conveyor through a drop hopper. In addition, since the inner material conveyor will swing laterally through the hoisting mechanism above during the dam pouring process, the bottom outlet of the spiral chute 8 on the other side of the climbing sleeve 2 needs to be rotatably connected to the front end of the inner material conveyor through a receiving hopper.

[0042] The working principle of this embodiment is as follows:

[0043] like Figures 1 to 6 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.

[0044] In addition, due to the spiral conveying function of the spiral chute 8, the material can be directly transferred from the top side of the outer surface of the climbing sleeve 2 to the bottom side of the outer surface of the climbing sleeve 2. This means that the material coming out of the end of the feeding belt conveyor (i.e., the location of the upper platform hopper) can be directly transferred to the front end of the inner material conveyor (i.e., the location of the lower platform receiving hopper). Therefore, there is no need for a material transfer conveyor belt, which simplifies the structure of the entire climbing platform.

[0045] Finally, the locking pin insertion process in this embodiment can be carried out manually as described above, or an automatic pin insertion process can be controlled by installing a horizontally mounted pin insertion cylinder.

[0046] 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.
