Description

Technical Field

[0001] This utility model relates to the field of semiconductor device packaging and testing technology, and more specifically, to a movable beam lifting tower. Background Technology

[0002] At present, building structures tend to develop in the direction of being taller, larger and more varied. Therefore, there are more and more cases of using the lifting construction method. At the same time, the construction conditions for lifting are becoming more and more complex. In order to cope with the complex construction conditions, construction units are gradually inclined to choose the simpler and less complicated independent lifting support tower.

[0003] During construction, due to the excessive height of the supporting tower, multiple transverse secondary beams are typically installed in the middle section of the tower to improve stability. However, these additional beams hinder the lifting operation of the lifting structure (such as a space frame). A traditional method for addressing the transverse beams of the supporting tower involves manually climbing the tower after the lifting structure approaches the beam, temporarily adding a transverse beam below the lifting structure, and then removing the existing beam above the lifting structure, allowing the lifting structure to cross over. This method is cumbersome and poses certain safety risks to the tower structure.

[0004] In addition, another traditional approach is to increase the cross-section of the main limbs of the support tower, thereby improving the stability of the support tower and eliminating the need for crossbeams, making it easier to lift the structure. However, this method requires significant construction work, and the support tower structure is bulky and difficult to install.

[0005] Based on the aforementioned technical problems, there is an urgent need for a solution with a relatively simple structure that facilitates the passage of structural improvements. Utility Model Content

However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0038] Figure 1 The front view of the movable beam lifting tower provided by an embodiment of the present invention is shown. Figure 2 The top structure of the tower of the movable beam lifting tower provided in the embodiment of this utility model is shown in top view. Figure 3 The tower body cross-sectional structure of the movable beam lifting tower provided in the embodiment of this utility model is as follows: Figure 4 The single-side node structure of the movable beam lifting tower provided in the embodiment of this utility model Figure 5 The crossbeam assembly structure of the movable lifting tower provided in the embodiment of this utility model.

[0039] Combination Figures 1 to 5 As can be seen, the movable lifting tower with crossbeam provided by this utility model includes a tower body as the main support structure and a force transmission component with transmission function; wherein, in order to realize the construction of the tower body, the tower body includes multiple (at least three, such as...) Figure 3As shown, more vertical main members 1 can also be set. Each main member 1 is parallel to the others. In order to improve the support stability of the entire tower body, a crossbeam assembly is set between two adjacent main members 1. In order to avoid the crossbeam assembly blocking the structure 15 to be lifted, the crossbeam assembly is slidably connected between two adjacent main members 1. In addition, each crossbeam assembly is connected to an external power device through a force transmission assembly.

[0040] In actual use, when the structure to be lifted 15 needs to be lifted, the crossbeam assembly can be lifted to the preset position (usually the top of the tower body) through the force transmission component, and then the structure to be lifted 15 can be lifted. After the construction of the structure to be lifted 15 is completed, the crossbeam assembly is lowered to the corresponding position. This avoids the crossbeam assembly from blocking the lifting structure, which can significantly improve work efficiency and ensure construction safety while ensuring the stability of the entire lifting tower and avoiding the safety risks of high-altitude operations.

[0041] In one specific embodiment of this utility model, to achieve the lifting of the crossbeam assembly by the force transmission component, a support beam 6 can be fixed on the upper part of the tower body (generally within 1000mm below the lifting beam 4); and the force transmission component includes a rope 9 (such as a steel wire rope) and a pulley block 8, wherein the pulley block 8 is disposed on the support beam 6, one end of the rope 9 is connected to the crossbeam assembly, and the other end of the rope 9 passes around the pulley block 8 and is connected to the power device. Further, to achieve the traction of the rope 9 by the power device, the power device may include a winch 10 (slow-speed winch 10) disposed on the ground, and the other end of the rope 9 passes around the pulley block 8 and is connected to the winch 10.

[0042] Specifically, in order to achieve a sliding connection between the crossbeam assembly and each main member 1, C-shaped grooves 7 can be provided on both sides of each main member 1; wherein, the C-shaped grooves 7 between two adjacent main members 1 are symmetrical to each other; and, T-shaped plates 13 adapted to the C-shaped grooves 7 are provided on both sides of the crossbeam assembly. The T-shaped plates 13 can be slidably connected to the C-shaped grooves 7, and both sides of each crossbeam assembly are slidably connected to the corresponding main member 1 through the T-shaped plates 13 and the C-shaped grooves 7.

[0043] More specifically, to realize the fabrication of the crossbeam assembly, the crossbeam assembly may include two horizontally arranged crossbars 11, one above the other, which are parallel to each other, and a cross brace 12 is connected between the two crossbars 11; wherein, a T-shaped plate 13 is fixed at both ends of each crossbar 11, and both sides of each crossbar 11 are slidably connected to the corresponding main member 1 through the T-shaped plate 13 and the C-shaped groove 7.

[0044] It should be noted that, under normal circumstances, during actual construction, multiple sets of crossbeam assemblies need to be set between two adjacent main members 1 (at least two sets, preferably two sets); and each crossbeam assembly between two adjacent main members 1 is connected to the same rope 9. With this arrangement, as the crossbeam assembly above the structure to be lifted 15 moves upward, the crossbeam assembly at the bottom of the tower body will also be lifted to the preset height, thereby ensuring the support stability of the entire movable crossbeam lifting tower.

[0045] In addition, it should be noted that in order to lift the structure 15 to be lifted, a conversion beam 3 needs to be set on the top of the tower body, and a lifting beam 4 needs to be set on the conversion beam 3. The lifting device 5 used to lift the structure 15 to be lifted needs to be set on the lifting beam 4. The initial position of the structure 15 to be lifted is at the bottom of the tower body. The lifting device 5 is connected to the structure 15 to be lifted through the steel strand 14. The structure 15 to be lifted is lifted in position through the lifting device 5 and the steel strand 14.

[0046] In addition, to further improve the support stability of the tower body, a base 2 can be fixed at the bottom of the tower body, and each main member 1 is fixedly connected to the base 2.

[0047] In the actual manufacturing process, each main member 1, as the main load-bearing member of the entire tower body, can be made of round tubes with a wall thickness greater than 12mm; the base 2, as a measure to stabilize the tower and transmit force, is welded to the main member 1 and is usually made of H-beams; the transfer beam 3 and lifting beam 4 at the top of the tower body, as the main force transmission structure of the lifting device 5, are also welded to the main member 1. The lifting beam 4 usually has a box-shaped cross section, and it is also one of the important members for stabilizing the tower; a support beam 6 is set within 1000mm below the lifting beam 4 and welded to the main member 1, mainly to ensure the stability of the top of the tower;

[0048] In addition, two C-shaped grooves 7 need to be set on the main member 1, and the C-shaped grooves on adjacent main members 1 are symmetrically arranged and connected to the side of the main member 1 by welding; the crossbeam assembly is installed between the two symmetrical grooves, and the movable crossbeam end is provided with a T-shaped plate 13. The T-shaped plate 13 is embedded in the C-shaped groove 7 and can move up and down in parallel; the movement of the crossbeam assembly is achieved by setting a pulley block 8 on the support beam 6, and the crossbeam assembly is connected by a rope 9 through the pulley block 8 and fixed to the winch 10. The winch 10 pulls the rope 9 to make the crossbeam move upward continuously; each crossbar 11 on the same side of the tower body needs to be connected by the same steel wire rope. When the rope 9 is pulled, the crossbar 11 can be moved synchronously. In order to ensure that the crossbar 11 does not get stuck and to improve the lateral stiffness, the adjacent crossbars 11 (two crossbars 11 in the same crossbeam assembly) are connected by cross bracing 12 to form a plate-like unit (i.e., crossbeam assembly).

[0049] Figure 6 The diagram illustrates the state of the movable beam lifting tower provided in an embodiment of the present invention in its first position during use. Figure 7 This illustration shows the second position of the movable beam lifting tower provided in an embodiment of the present invention during use. Figure 8 The third position of the movable lifting tower with crossbeam provided in the embodiment of this utility model during use.

[0050] Combination Figures 6 to 8 As shown, the specific construction process of the movable beam lifting tower provided by this utility model is as follows:

[0051] First, move the entire movable lifting tower of the crossbeam to the lifting point, and then firmly fix the base 2 to the floor or ground using the embedded parts.

[0052] Next, a set of crossbeam assemblies is embedded into the C-shaped slot at the bottom of the tower body, and the crossbeam assembly is lifted to the tower stabilizing crossbeam setting point by rope 9 and pulley block 8. Through this process, the crossbeam assemblies on each side of the tower body are set in sequence, and the crossbeam assemblies are arranged at equal intervals.

[0053] Then, after the entire tower structure is installed, install the relevant lifting devices 5, steel strands 14, etc., connect the lifting devices 5 to the structure to be lifted 15, and complete the preparations before lifting (such as...). Figure 6 (As shown).

[0054] Subsequently, the lifting structure 15 will begin its first lifting operation, stopping when the height reaches 50mm below the first crossbeam assembly, completing the first lifting distance (e.g. Figure 7 (As shown).

[0055] Then (after completing one lifting height), the worker operates the winch 10 at the bottom of the tower to drive the rope 9 and lift the entire crossbeam assembly installed on the main body of the tower upwards to the next preset crossbeam height. At the same time, a crossbeam assembly is added below the tower to fill the gap where the crossbeam has moved up, ensuring that the number of equally spaced crossbeams 11 in the tower structure is (e.g., ...). Figure 8 (As shown).

[0056] It should be noted that during the lifting process of the structure to be lifted 15, the lifting can be divided into two or three lifting operations according to the spacing of the crossbeam components until it is in place. During the entire lifting process, the overall structure of the main limb 1 and the crossbeam components remains basically unchanged, which can ensure the support stability of the entire movable crossbeam lifting tower.

[0057] As per the above reference Figures 1 to 8A movable beam lifting tower according to the present invention has been described by way of example. However, those skilled in the art should understand that various modifications can be made to the movable beam lifting tower proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
