Description

Technical Field

[0001] The utility model relates to the field of tower crane leg anchoring, and more specifically, to a tower crane leg anchoring device. Background Art

[0002] Tower crane leg anchoring devices are usually designed to ensure the stability and safety of tower cranes during operation. Especially under windy or other external environmental influences, tower crane legs are usually composed of several thick steel pipes or steel plates, and their lengths are usually adjustable to adapt to different working sites and terrain conditions. The anchoring foundation for fixing the legs is generally a concrete foundation or steel anchor bolts. The design of the tower crane leg anchoring device should take into account the stability and safety requirements of the tower crane under different working conditions, and also consider the convenience of installation and movement.

[0003] In the specific anchoring of tower crane legs, existing tower crane legs are usually pre-buried together with reinforced concrete during installation to achieve a stable effect. Although this method can install the tower crane legs, after use, a large piece of concrete needs to be dug out and then transported. If it is convenient for transportation, the pre-burial is too shallow and the anti-overturning ability is insufficient, which is likely to cause accidents and is not convenient for operators to use. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a tower crane leg anchoring device that overcomes the above technical problems or at least partially solves the above problems.

[0005] The utility model is implemented as follows:

Specific embodiments

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1 - 4, the present utility model provides a technical solution: a tower crane leg anchoring device, including a mounting plate 12, a leg 11 is arranged inside the mounting plate 12, pre-buried steel bars 13 are arranged at the four corners of the mounting plate 12, a limiting block 18 is sleeved on the surface of the pre-buried steel bar 13, and a threaded rod 19 is arranged inside the limiting block 18. Through the mutual cooperation of the tower crane main body 25, the leg 11, the limiting block 18, the pre-buried steel bar 13, the threaded hole 16 and the threaded rod 19, when the operator needs to anchor the leg 11 of the tower crane main body 25, first, the pre-buried steel bar 13 can be installed into the concrete 26. The operator can align the limiting block 18 with the pre-buried steel bar 13 and then move it downward. When it moves to the ground of the concrete 26, the operator can insert the threaded rod 19 into the threaded hole 16. Thus, through the double fixation of the pre-buried steel bar 13 and the threaded rod 19, the stability of the tower crane main body 25 can be ensured, and the leg 11 can be prevented from shifting. The mounting plate 12 outside the pre-buried steel bar 13 also increases the contact area between the pre-buried steel bar 13 and the concrete 26, making the connection between the pre-buried steel bar 13 and the concrete 26 more firm. When transporting, only the mounting plate 12 needs to be dug out, which is convenient for the operator to transport. Compared with the situation where the pre-buried steel bar 13 and the concrete 26 are pre-buried together, the demolition is more convenient and fast, and it is also more convenient to use when used again.

[0027] Referring to Figures 1 - 4 , in a preferred embodiment, limiting frames 2 are arranged on both sides of the leg 11, bolts 22 and limiting rods 24 are arranged inside the limiting frames 2, the limiting blocks 18 are arranged in two groups, and the two groups of limiting blocks 18 are respectively arranged on both sides of the leg 11. Concrete 26 is arranged outside the mounting plate 12, a groove body is opened inside the concrete 26, the mounting plate 12 is arranged inside the groove body, reinforcing bar holes 14 are opened at the four corners of the mounting plate 12, and the pre-buried steel bars 13 are arranged inside the reinforcing bar holes 14. Through the mutual cooperation of the leg 11, the limiting frames 2, the limiting rods 24, the bolts 22, the pre-buried steel bars 13 and the threaded rods 19, when the operator needs to improve the stability of the leg 11, the operator can install the two groups of limiting frames 2 on both sides of the leg 11 according to the usage situation. After the installation is completed, the operator can install the limiting rods 24 and the bolts 22 into the correspondingly adapted limiting holes 23 and mounting holes 21 respectively, so as to install the limiting frames 2, and then cooperate with the pre-buried steel bars 13 and the threaded rods 19, which can further improve the stability of the tower crane main body 25 and the leg 11 and is convenient for the operator to use.

[0028] Referring to Figures 1 - 4In a preferred embodiment, an awl 17 is provided at the bottom of the leg 11, and the awl 17 is provided to facilitate the installation of the leg 11. A mounting groove 15 is provided inside the mounting plate 12, and the leg 11 is arranged inside the mounting groove 15. Threaded holes 16 are provided on both sides of the mounting plate 12, and the threaded rod 19 is arranged inside the threaded hole 16. A plurality of limiting holes 23 are provided on both sides of the leg 11, and the limiting rod 24 is arranged inside one group of the limiting holes 23. A plurality of mounting holes 21 are provided on both sides of the leg 11, and the bolt 22 is arranged inside one group of the mounting holes 21. A tower crane body 25 is provided on the top of the leg 11.

[0029] Specifically, the working process or working principle of the anchoring device of the tower crane leg 11 is as follows: in the specific anchoring of the tower crane leg 11, the existing tower crane leg 11 is usually pre-buried together with the reinforced concrete 26 during installation to achieve a stabilizing effect. Although this method can install the tower crane leg 11, after use, a large piece of concrete 26 needs to be dug out and then transported. If it is convenient to transport, the shallow pre-buried concrete 26 has insufficient anti-overturning ability, which is easy to cause accidents and inconvenient for operators to use. Therefore, the technical solution can solve the above problems. When the operator needs to anchor the tower crane body 25 leg 11, the quasi-embedded steel bar 13 can be installed into the interior of the concrete 26 first. The operator can align the limit block 18 with the embedded steel bar 13 and then move it downward. When it moves to the ground of the concrete 26, the operator can insert the threaded rod 19 into the threaded hole 16, so that the double fixation of the embedded steel bar 13 and the threaded rod 19 can be achieved. To ensure the stability of the tower crane body 25 and avoid the deviation of the support leg 11, the outer mounting plate 12 of the embedded steel bar 13 also increases the contact area between the embedded steel bar 13 and the concrete 26, so that the connection between the embedded steel bar 13 and the concrete 26 is more firm. When transporting, only the mounting plate 12 needs to be dug out, which is convenient for the operator to transport. Compared with the situation where the embedded steel bar 13 and the concrete 26 are embedded together, the removal is more convenient and quick, and it is also more convenient to use again. When the operator needs to improve the stability of the support leg 11, the operator can install the two sets of limit frames 2 on both sides of the support leg 11 according to the usage. After the installation is completed, the operator can install the limit rod 24 and the bolt 22 to the corresponding limit hole 23 and the mounting hole 21 respectively, so that the limit frame 2 can be installed, and then it can cooperate with the embedded steel bar 13 and the threaded rod 19, which can further improve the stability of the tower crane body 25 and the support leg 11, and is convenient for the operator to use. At this point, all processes are completed.

[0030] It should be noted that the tower crane main body 25 is electrically connected to an external power supply and is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be elaborated in detail.
