Abstract
Description
Technical Field
[0001] The utility model belongs to the field of tower crane jacking, and particularly relates to an automatic anti-slip structure for tower crane jacking. Background Art
[0002] Tower cranes are indispensable large-scale construction equipment in the modern construction industry. Their efficient lifting capacity provides great convenience for the construction of various high-rise buildings. However, as the height of buildings continues to increase, tower cranes need to perform jacking operations regularly to increase the number of standard sections of the tower body to meet higher construction needs.
[0003] In the current tower crane jacking operation, oil cylinders are generally used for jacking. Through two or more jacking processes of the oil cylinder, the tower crane can achieve an additional section space of a standard section. In this process, the jacking beam needs to rely on the swing of the jacking oil cylinder to embed into the step of the tower standard section. In order to ensure the stability and safety of the jacking, the jacking oil cylinder, the frame beam and the jacking beam are usually connected by pins.
[0004] However, this traditional jacking method has many shortcomings. First, since the jacking beam needs to be manually inserted into the step, the operator needs to climb up and down with the jacking beam, which not only increases the labor intensity of the operator, but also increases the safety risks during the operation. Secondly, most jacking beams are connected to the steps with open quick pins. Although the cylinder can automatically fall into place after rotating into place, the insertion and removal of the anti-drop pin still needs to be done manually. Since the position of the jacking beam in the step hole is uncertain before the anti-drop pin is inserted, the operator needs to repeatedly align the hole position, which greatly increases the complexity and workload of the operation.
[0005] Especially in high-altitude working environments, operators climbing up and down not only increases the difficulty of operation, but may also lead to safety accidents. At the same time, since the connection between the jacking beam and the steps requires manual alignment of the holes, the operator's skills and experience play a vital role in the success of the jacking operation. This dependence on the operator not only increases the uncontrollability of the operation, but also limits the efficiency of the tower crane jacking operation. Utility Model Content

[0024] The following will be combined with the attached Figure 1-Figure 5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, an automatic anti-slip structure for tower crane jacking includes a sleeve frame 3, such as Figure 3 As shown, a horizontal web bar 5 is provided on one side of the sleeve 3, and a hanging plate assembly is provided on one side of the sleeve 3, and a second ear plate 12 is fixedly connected to one side of the horizontal web bar, and the hanging plate assembly includes a second rotating shaft 14, and a third ear plate 15 is fixedly connected to the second rotating shaft 14, and the second ear plate 12 and the third ear plate 15 are connected through a second telescopic mechanism 13, and hanging plates 16 are fixedly connected at both ends of the second rotating shaft 14, and the hanging plate 16 is a triangular structure, and second fixed ear plates 18 are also fixedly connected at both ends of the horizontal web bar 5, and the lower end of the second fixed ear plate 18 is movably connected to the top angle of the hanging plate 16; after the standard section 1 is lifted upward into place, the second telescopic mechanism 13 is extended, and the hanging plate 16 rotates around the connection between the second fixed ear plate 18 under the action of the second rotating shaft 14 and the second fixed ear plate 18, and the other corner of the hanging plate 16 is used to resist the lower part of the step 2, so as to realize the anti-slipping of the standard section 1, reduce manual intervention, and improve the lifting efficiency of the tower crane.
[0027] like Figure 3 As shown, a first ear plate 6 is fixedly connected to one side of the frame crossbeam 4 at the upper end of the frame 3, and the hanging plate assembly also includes a first telescopic mechanism 7, and the upper end of the first telescopic mechanism 7 is movably connected to the first ear plate 6. A first rotating shaft 8 is provided at the lower part of the frame crossbeam 4, and the lower end of the first telescopic mechanism 7 is movably connected to the first rotating shaft 8. Hanging boots 10 are fixedly connected to both ends of the first rotating shaft 8, and first fixed ear plates 9 are fixedly connected to both ends of the horizontal web 5, and one side of the hanging boot 10 is movably connected to the first fixed ear plate 9. After the standard section 1 is lifted to a certain height, the upper surface of the step 2 is abutted against the lower surface of the hanging boot 10, and the hanging boot 10 and the hanging plate 16 work together to hold the step 2, thereby limiting the movement of the standard section 1 in the up and down directions and ensuring the stability of the lifting of the standard section 1.
[0028] like Figure 4 , Figure 5 As shown, the hanging plate 16 and the hanging boot 10 each include two side plates, which are fixedly connected via a connecting plate, wherein the two side plate ends of the hanging plate 16 are fixedly connected with a pad 17, and the two side plate ends of the hanging boot 10 are fixedly connected with a clamping plate 11. After the standard section 1 is lifted into place, the pad 17 and the clamping plate 11 hold the step 2; a limiting groove is formed between the two side plates of the hanging plate 16 and the hanging boot 10, and the step 2 is clamped in the limiting groove, which limits the horizontal displacement of the step 2 and further ensures the stability of the lifting of the standard section 1.
[0029] like Figure 3 As shown, the first telescopic mechanism 7 and the second telescopic mechanism 13 adopt hydraulic cylinders.
[0030] In other embodiments, the first telescopic mechanism 7 and the second telescopic mechanism 13 may also be electric push rods.
[0031] like Figure 3As shown, the first rotating shaft 8 and the second rotating shaft 14 both adopt a square tube structure to avoid axial rotation between the first rotating shaft 8 and the hanging shoe 10, or between the second rotating shaft 14 and the hanging plate 16, thereby ensuring the stability of the hanging plate assembly.
[0032] Before the standard section 1 is lifted, the hanging plate 16 and the hanging shoe 10 hold the step 2. During the lifting, the second telescopic mechanism 13 contracts, and the pad 17 at the end of the hanging plate 16 is separated from the step 2. The lifting cylinder (not shown in the figure) first drives the standard section 1 to move downward a certain distance, and then the first telescopic mechanism 7 contracts, and the hanging shoe 10 flips outward to leave space for the lifting of the standard section 1. Then the lifting cylinder drives the standard section 1 to lift upward again. When the step 2 is lifted to pass over the hanging shoe 10, the first telescopic mechanism 7 extends, driving the hanging shoe 10 to flip until the upper surface of the step 2 of the next standard section 1 is against the card plate 11 of the hanging shoe 10, the lifting cylinder stops lifting, and the second telescopic mechanism 13 extends again, using the pad 17 at the end of the hanging plate 16 to resist the lower surface of the step 2, to achieve automatic anti-slippage of the lifting operation of the standard section 1, reduce the operating difficulty of the tower crane lifting and the labor intensity of the operators, and improve the efficiency and safety of the tower crane lifting construction.
