[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-9 This utility model provides a technical solution: a crane support base, including a base 1 for supporting a crane support frame 2, and further including:

[0031] The movable base 4 is set at the lower end of the base 1 with adjustable angles;

[0032] Adjustment device 5 is disposed between base 1 and movable seat 4, and is used to adjust the installation position of movable seat 4;

[0033] Adjustment device 5 includes:

[0034] The mounting component is located between the base 1 and the movable seat 4 to support the movable seat 4;

[0035] A rotating component, mounted on the mounting component, is used to adjust the mounting height of the movable seat 4.

[0036] It should be noted that during operation, the base 1 is installed in the designated position. When the installation position of the base 1 needs to be adjusted, the adjusting device 5 drives the movable seat 4 downward, making the movable seat 4 contact the ground. The movable seat 4 rolls on the ground, facilitating the movement of the entire base 1 on the ground. After the installation position of the base 1 is adjusted, the adjusting device 5 is rotated again to move the movable seat 4 upward, separating the movable seat 4 from the ground and making contact with the ground. The base 1 is then fixed to the ground, completing the installation of the crane base 1. Then, the crane support frame 2 is connected to the base 1. The movable seat 4 allows the crane support base 1 to move easily between different positions, especially when frequent adjustments to the working position are required, greatly improving work efficiency. The adjusting device 5 allows the installation position and height of the movable seat 4 to be adjusted according to actual needs, satisfying both the stability of the fixed base 1 and facilitating the movement of the base 1, reducing the difficulty of operation and improving work efficiency.

[0037] In one embodiment, the mounting component includes a connecting plate 51 fixed to the lower end of the base 1, a connecting block 511 disposed at the lower end of the connecting plate 51, a fixing plate 52 disposed at the upper end of the movable seat 4, and a fixing block 521 disposed at the upper end of the fixing plate 52. The rotating component is disposed between the connecting block 511 and the fixing block 521.

[0038] This design is for reference. Figure 7 The connecting plate 51 and the fixed plate 52 are fixed on the base 1 and the movable seat 4 respectively, forming a stable support structure. The rotating part is set between the connecting block 511 and the fixed block 521, so that the position and height of the movable seat 4 relative to the base 1 can be flexibly adjusted, which meets the flexible adjustment requirements of the crane under different working environments and operation needs, and improves the operation efficiency.

[0039] In one embodiment, the rotating component includes a scissor lift rod 53 disposed between the connecting block 511 and the fixed block 521, a moving block 54 disposed on one side of the scissor lift rod 53, a mounting block 55 disposed on the other side of the scissor lift rod 53, and a screw 56 rotatably sleeved on the mounting block 55, the screw 56 being threadedly connected to the moving block 54.

[0040] This design is for reference. Figure 7 By rotating the screw 56, the screw 56 is threadedly connected to the moving block 54, causing the moving block 54 to move on the screw 56, which in turn drives the scissor lifting rod 53 to move the moving seat 4 up and down, thereby achieving fine adjustment of the height of the moving seat 4. The scissor lifting rod 53 is symmetrically arranged about the moving block 54, which makes the movement of the moving seat 4 more stable.

[0041] In one embodiment, a handle 57 is provided on one side of the screw 56, and the screw 56 is fixedly connected to the mounting block 55 by a fixing bolt 58.

[0042] This design is for reference. Figure 9 The handle 57 allows the operator to more easily rotate the screw 56 for height adjustment. The screw 56 is fixedly connected to the mounting block 55 by the fixing bolt 58, ensuring that the screw 56 will not loosen or fall off due to force during operation, thus enhancing the stability of the moving seat 4 and improving the safety of the crane support base 1.

[0043] In one embodiment, the lower end of the movable seat 4 is provided with a wheel 41.

[0044] This design is for reference. Figure 8 The design of the wheels 41 allows the movable seat 4 to move easily between different positions. This greatly improves operational efficiency and flexibility for cranes that need to frequently adjust their working position or move between different construction sites.

[0045] In one embodiment, a counterweight 3 is provided at the upper end of the base 1, and a positioning frame 12 for fixing the counterweight 3 is provided at the upper end of the base 1. The counterweight 3 is sleeved on the positioning frame 12, and a support leg 11 is fixed at the lower end of the base 1.

[0046] This design is for reference. Figure 1-6 The addition of counterweight 3 significantly increases the weight of base 1, thereby improving the stability of the entire structure. The design of positioning frame 12 makes the installation and positioning of counterweight 3 simple and convenient. Operators can easily place counterweight 3 onto positioning frame 12 and ensure it is stable and does not loosen. This design reduces installation time and improves work efficiency. The design of support legs 11 allows base 1 to adapt to different working environments. Whether on flat ground or slightly uneven terrain, support legs 11 can provide stable support, ensuring the normal operation of the crane.
