[0039] Example 2

[0040] The structure and principle of Example 2 are similar to those of Example 1, except that: a preferred structural form of the mounting frame is provided. The mounting frame is divided into multiple parts, including a support frame 1-1 and a clamping frame 1-2;

[0041] At least one support frame is included, and a plurality of placement slots are arranged on the support frame; the placement slots on the plurality of support frames correspond to each other one by one, and the corresponding placement slots have a common center line; the support frame is fixedly arranged on the ground or an external mounting platform;

[0049] Example 4

[0050] The structure and principle of Example 4 are similar to those of Example 3, except that a synchronous frame 6 is provided between the pressure blocks in order to achieve synchronous clamping of steel bars of different thicknesses, the top of which is connected to the lower surface of the pressure blocks, and the bottom of which is fitted with the top of each clamping column. The synchronous frame is provided to ensure that each support column is subjected to the same pressure.

[0051] In Example 4, preferably, the number of clamping columns is an even number, and the clamping columns are distributed at equal intervals; the synchronous frames include two, and an overlapping area is provided between the two synchronous frames, and the two synchronous frames are symmetrically distributed with respect to the center plane of all the clamping columns; a spring 7 is sleeved on each clamping column, and the spring is located between the bottom of the synchronous frame and the supporting frame near the guide hole. In the embodiment shown in the figure, a contact plate 3-1 is provided at the top of the clamping column, and the two ends of the spring abut between the lower surface of the contact plate and the mounting frame; the setting of the spring can play a rebound role.

[0054] A single pressure wheel or a double pressure wheel package is rotatably connected to the bottom of the vertical section; the double pressure wheel package includes a connecting rod and a pressure column, both ends of the connecting rod are connected to the pressure column, the pressure column and the single pressure wheel both contact the upper end of the clamping column, and the middle part of the connecting rod is rotatably connected to the bottom end of the vertical section; so that the interval distances between two adjacent single pressure wheels, between the single pressure wheel and the pressure column, and between the pressure columns are equal.

[0055] A corresponding number of vertical sections are arranged according to the number of clamping columns below the horizontal section, and a double pressing wheel package or a single pressing wheel is arranged at the bottom end of the vertical section.

[0056] In the embodiment shown in the figure, six clamping columns are included, the frame presents a U-shaped structure, and the vertical sections on both sides are respectively provided with a double pressure wheel package and a single pressure wheel.

[0057] The utility model also provides a multi-layer multi-steel bar stable clamping device, comprising a plurality of the multi-steel bar stable clamping devices as described above, wherein the planes where the placement slots in each multi-steel bar stable clamping device are located are parallel to each other, thereby realizing the clamping operation of the multi-layer steel bars.

[0058] The working principle of this utility model:

[0059] The multi-steel stable clamping device can realize synchronous clamping of multiple steel bars with high stability. The operator drives the rotating wheel to rotate, and the rotating wheel drives the threaded rod to rotate. The threaded rod is threadedly connected to the clamping frame. Therefore, the threaded rod will move downward, further driving the pressure block to move downward. Since the pressure block is vertically slidably connected to the inside of the clamping frame, the pressure block will be limited and cannot rotate, and the threaded rod will drive the pressure block to move downward. The pressure block then drives the synchronous member to move downward synchronously, so that the clamping column below moves downward to clamp all the steel bars.

[0060] When the power component drives the pressure block to move downward, the synchronous frame will also move downward. Since the synchronous frame is rotatably connected to the bottom of the pressure block, the single pressure wheels and pressure columns at both ends of the synchronous frame will move downward synchronously. Even if the thickness of the steel bars below is different, the setting of the synchronous frame and the connecting rod can enable the clamping column below to clamp the steel bars, and there will be no problem of the steel bars not being clamped and becoming loose.

[0061] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of patent application of the present invention still fall within the protection scope of the present invention.
