Technical Field

[0001] This utility model relates to the field of tower belt conveyor technology, and in particular to a manually locked tower belt conveyor tower climbing frame. Background Technology

[0002] like Figure 7 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

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-6 As shown, a manually locked tower crane tower 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 manual pin-locking mechanism 7 is provided between the truss structure 2 and the surface of the tower 1 for locking the truss structure 2 onto the surface of the tower 1.

[0025] 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.

[0026] 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, and a ladder 2.4 between the upper platform 2.2 and the lower platform 2.3. In this embodiment, the ladder 2.4 facilitates manual inspection or manual pin insertion.

[0027] Preferably, such as Figure 3 and 4 As 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.

[0028] 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.

[0029] In this embodiment, the telescopic device 3 may include the following two implementation methods:

[0030] 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.

[0031] Example 2: As Figure 3 and 4 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.

[0032] Preferably, the inner side of the truss structure 2 is further provided with a plurality of sliding shoes 6 that slide in contact with the surface of the tower 1. For example... 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.

[0033] 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.

[0034] Preferably, the manual pin-threading 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, and an ear plate 5 is also fixedly provided on the surface of the corresponding area of ​​the tower 1. The ear plate 5 has a hole for inserting a locking pin, and the locking plate 7.1 is connected to the ear plate 5 through the locking pin. In this embodiment, after each climbing process of a certain distance is completed, 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, the locking pin is inserted through the through hole 4, and 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 truss structure 2 is hung on the surface of the tower 1 through the locking plate 7.1.

[0035] 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.

[0036] The working principle of this embodiment is as follows:

[0037] Taking Example 2 as an example, such as Figure 3 and 4 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 through the through hole 4, and the locking pin inserted between 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.

[0038] 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.
