[0015] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] In the present application, the telescopic rod 7 can be a hydraulic oil cylinder or a hydraulic cylinder; according to different models, it can be purchased directly from the market and installed for matching. The rolling bearing 10 is also purchased and installed for matching according to the specific model. The rising height range of the movable seat 6 is 30-50cm.

[0017] See Figure 1 and Figure 2 The figure shows a tower crane lower support tooling, including a base 1, a bottom plate 2 is installed at the four corners of the upper end of the base 1, and an ear seat 3 is vertically arranged on the bottom plate 2; a hinge hole 4 is provided at the upper end of the ear seat 3, and the hinge hole 4 is connected to a fixed seat 5 through an axle pin, and the fixed seat 5 is a circular ring structure, and a movable seat 6 is movably arranged in the middle of the fixed seat 5, and a telescopic rod 7 is arranged at the lower end of the movable seat 6.

[0018] The bottom plate 2 is fixed to the upper end surface of the base 1 by fastening bolts. An ear plate 8 is arranged on the outer wall of the fixed seat 5, and the ear plate 8 is connected to the hinge hole 4 by a pin. A telescopic cover 9 is arranged on the outer side of the telescopic rod 7, and the lower end of the telescopic cover 9 is fixedly mounted on the bottom plate 2, and the upper end of the telescopic cover 9 is connected to the lower end surface of the movable seat 6. The movable seat 6 and the ear plate 8 are an integral structure. A plurality of rolling bearings 10 are also arranged between the fixed seat 5 and the movable seat 6.

[0019] The operating principle of the tower crane lower support tooling is as follows:

[0020] First of all, during normal use, the operator can control the operation of the telescopic rod 7 through an external controller. The extension of the telescopic rod 7 will drive the movable seat 6 to be pushed out, so that the support height can be adjusted; when it needs to be adjusted to a lower level, the telescopic rod 7 is controlled to retract, so that the support height can be adjusted downward; the operation is convenient and quick, and the present application provides appropriate buffering and decompression support for the lower support tooling before it is subjected to heavy pressure through the hinge connection between the ear seat 3 and the ear plate 8, which can largely ensure the stable use of the lower support tooling and increase the service life of the overall lower support tooling; and ensure the stable, safe and effective support needs of the overall tower crane.

[0021] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
