[0002] The embedded welding of tower cranes requires a foundation to be made during installation. Generally, the fixed legs are embedded in the concrete to ensure the safety of the embedded welding of tower cranes. However, in some cases, the embedded parts need to be welded when installing tower cranes.
[0003] According to the existing patent document with publication number CN203393734U, a pre-embedded welded foundation structure for a tower crane includes a roof foundation plane, characterized in that: the roof foundation plane is pre-embedded with four embedded parts, the four embedded parts are distributed at the four vertices of a rectangle, a number of anchor bars are welded through holes in the steel plate of the embedded parts, the steel plate and anchor bars of the embedded parts are pre-embedded in the concrete of the roof foundation plane, and the four fixed legs pre-embedded and welded to the tower crane correspond to each embedded part. When this technical solution is used, the foundation structure can be used in environments such as rooftops where fixed legs cannot be pre-embedded, thereby increasing the scope of application of pre-embedded welding of tower cranes. It has little impact on the structure and appearance of the building. Regarding the above technical solution, although this solution has achieved an increase in the scope of application, it cannot clamp and position the workpieces during welding, which is inconvenient during use.

The support seats cooperate with the lifting mechanism to increase the contact area between the support legs and the base. After the support legs are limited and fixed by the support seats, it is convenient for the later welding between the support legs and the base.
[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a tower crane embedded support leg welding device, including a device body, the device body including a base, a fixing hole is opened on the base, a cutting is welded inside the fixing hole, the bottom of the base is installed with concrete, the base is fixedly installed inside the concrete by cutting, the top of the base is movably installed with a support leg, the side of the support leg is movably installed with a support seat, the support seat is respectively fixedly installed with a displacement mechanism, and the displacement mechanism is installed with a movable column.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] See also Figures 1 to 4 The utility model provides a technical solution: a pre-embedded support leg welding device for a tower crane, comprising a device body, wherein the device body comprises a base 1, a fixing hole 11 is opened on the base 1, a cutting 2 is welded inside the fixing hole 11, and concrete 15 is installed at the bottom of the base 1, and the base 1 is fixedly installed inside the concrete 15 through the cutting 2, and a supporting leg 3 is movably installed on the top of the base 1, and a supporting seat 4 is movably installed on the side of the supporting leg 3, and a displacement mechanism 5 is fixedly installed on the supporting seat 4, and a movable column 6 is installed on the displacement mechanism 5, and a mounting hole 13 is opened on the inner wall of the supporting seat 4, and a threaded column 14 is rotatably installed inside the mounting hole 13, and the displacement mechanism 5 is an electric push rod, which pushes the support seat 4 to move, and the movement completes the clamping and fixation of the support legs 3 of different thicknesses.
[0021] In this embodiment, a fixed seat 7 is rotatably installed on the side of the support seat 4, one end of the threaded column 14 is fixed on the fixed seat 7, and a threaded hole 12 is opened at one end of the movable column 6, and the threaded hole 12 is rotatably connected to the threaded column 14, and the movable column 6 is movably installed inside the mounting hole 13, and a reinforcing plate 10 is movably installed between the base 1 and the support leg 3, and the reinforcing plate 10 is welded to the base 1 and the support leg 3, and a switch 8 is fixedly installed on the support seat 4, and a lifting mechanism 9 is fixedly installed inside the support seat 4, and one end of the lifting mechanism 9 is movably contacted with the base 1, and the lifting mechanism 9 is an electric push rod, which pushes the support seat 4 to move upward, and the height of the support seat 4 is adjusted according to the height of the reinforcing plate 10, and the limiting fixation of the reinforcing plate 10 is completed by cooperating with the movable column 6 and the support seat 4.
[0022] When the device is in use, concrete 15 is poured at the position where the tower crane needs to be installed. The concrete 15 provides a support point for the tower crane. After the concrete 15 is poured, the base 1 is placed on the top of the concrete 15, and the cutting 2 is installed in the inside of the fixing hole 11. The cutting 2 is welded to the inside of the fixing hole 11 through an external welding device.

After the support seat 4 moves upward, the reinforcement plate 10 is installed at the bottom of the movable column 6. The support seat 4 descends and squeezes the top of the reinforcement plate 10 downward through the movable column 6. The reinforcement plate 10 is limited by the movable column 6 to avoid damage caused by holding the reinforcement plate 10 during the later welding.
