The clamp unit comprises a rigid clamp outer frame with two or more friction surfaces protruding from the inner side of the clamp outer frame. The shape of these friction surfaces matches the shape of the corresponding outer surface of the pier column. The pier column clamp device of the present invention can not only be used on special-shaped pier columns, but also increases the effective friction area and improves the load-bearing capacity.

[0004] However, the pier column clamps are usually independent entities, which are respectively arranged at each vertical surface of the pier column. There is a lack of connection between the clamps, resulting in poor stability between the clamps, which affects the supporting effect of the clamps on the pier column as a whole. Utility Model Content

[0005] In response to the existing problems in the prior art, pier column clamps are usually independent entities, respectively installed on the various facades of the pier column. The lack of connection between the clamps leads to poor stability between the clamps, affecting the overall support effect of the clamps on the pier column. The utility model provides a pier column clamp connection device that can connect the two clamps in each group to form an integrated clamp structure. Compared with traditional single independent clamps, the integrity is stronger, the tightness and stability of the connection between adjacent clamps are increased, and the clamp support effect on the pier column is more stable.

DETAILED DESCRIPTION

[0023] The following is a combination of specific implementation cases and attached Figures 1 to 3 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0024] See Figures 1 to 3The brackets 3 are connected to the support rails 2 and 3 and are fixed to the support rails 2. The brackets 3 are connected to the support rails 2 and 3 and are fixed to the support rails 2. The brackets 3 are connected to the support rails 2 and 3 and are fixed to the support rails 2.

[0025] Main references Figures 1 to 3 As shown, a second support arm 20 is fixedly installed on the column 2, and a top seat 8 is fixedly installed on the top of the second support arm 20. Screws 9 are respectively provided on the left and right sides of the inner wall of the top seat 8 through bearings for rotation. External threads in opposite directions are provided on the front and rear sides of the screw 9. A movable plate 10 is threadedly sleeved on the screw 9. A limit rod 11 is fixedly installed in the top seat 8. The limit rod 11 is arranged parallel to the screw 9. The movable plate 10 is slidably sleeved on the limit rod 11. A second groove 12 is opened at the free end of the movable plate 10, and the movable pin 7 is slidably embedded in the inner cavity of the second groove 12. The two movable plates 10 on the screw 9 move synchronously toward the middle of the screw 9. As the movable plate 10 moves, the movable pin 7 moves along the inner cavity of the second groove 12, while driving the extension arm 5 and the clamp 6 to move synchronously toward the direction close to the middle of the screw 9, thereby realizing that the two clamps 6 correspondingly arranged in the front and rear gradually approach each other until the side wall of the clamp 6 fits with the edge of the intersection of the pier column, and the four clamps 6 fit and clamp the side wall of the pier column.

[0026] Main references Figure 2As shown, the rear end portion of each movable plate 10 extends out of the side wall of the top seat 8, and the rear end portion of the movable plate 10 is installed with a first bevel gear 13, and the rear side wall of the top seat 8 is fixedly installed with multiple mounting seats 14, and the mounting seat 14 passes through from left to right and is rotatably provided with a rotating rod 15, and the left and right ends of the rotating rod 15 are respectively installed with a second bevel gear 16, and the rear side wall of the top seat 8 is installed with a motor 17 through a motor frame. The output end of the motor 17 is connected to the rotating rod 15, and the rotating rod 15 is driven by the turned-on motor 17 to rotate, so as to prompt the two second bevel gears 16 on the rotating rod 15 to synchronously drive the first bevel gear 13 at the corresponding position to rotate, and the two second bevel gears 16 are set in the same direction. Since the two second bevel gears 16 are set in the same direction, the two first bevel gears 13 have the same rotation direction, and the rotating first bevel gear 13 drives the screw 9 installed on the corresponding front side to rotate, thereby driving the two movable plates 10 on the screw 9 to move synchronously toward the middle of the screw 9.

[0027] In addition, the top seat 8 is configured to be U-shaped, and the opening direction of the top seat 8 faces forward, so that the top seat 8 can be surrounded and arranged outside the pier column without the need to install the top seat 8 from the top of the pier column.

[0028] Main references Figure 1 and Figure 3 As shown, a plurality of universal wheels 18 are respectively installed at the bottom end of the base 1, and the universal wheels 18 make it easier to move the entire device so that it can be quickly moved to the pier to be tightly embraced and positioned.

[0029] A pier 19 is provided on the inner side of the hoop 6, and the intersection edge of the side wall of the pier 19 is in contact with the inner wall of the hoop 6. The extension arm 5 and the hoop 6 are synchronously moved toward the middle of the screw 9, thereby achieving the gradual approach of the two corresponding hoops 6 in the front and back until the side wall of the hoop 6 is in contact with the edge of the intersection of the pier 19, and the side wall of the pier 19 is tightly clamped with the help of four hoops 6.

[0030] It is worth noting that the motor 17 in this application adopts a self-locking motor with a lockable output end commonly used on the market. When it stops working, the output end can self-lock and will not rotate under external force. The motor 17 is a forward and reverse motor, and its output end can rotate forward or reverse according to usage requirements. The above-mentioned existing components will not be described in detail here.

[0031] The working principle of the pier column clamp connection device of this embodiment is as follows:

[0032] The motor 17 is turned on to drive the rotating rod 15 to rotate, so as to prompt the two second bevel gears 16 on the rotating rod 15 to synchronously drive the first bevel gear 13 at the corresponding position to rotate. Since the two second bevel gears 16 are arranged in the same direction, the two first bevel gears 13 rotate in the same direction. With the help of the rotating first bevel gear 13, the screw rod 9 installed on the corresponding front side is driven to rotate, and then the two movable plates 10 on the screw rod 9 are driven to move synchronously toward the middle of the screw rod 9. As the movable plate 10 moves, the movable pin 7 is prompted to move along the inner cavity of the second groove body 12, while the extension arm 5 and the clamp 6 are driven to move synchronously toward the middle of the screw rod 9, thereby realizing that the two clamps 6 arranged in the front and rear correspondingly are gradually approaching until the side wall of the clamp 6 is in contact with the edge of the intersection of the pier column 19, and the four clamps 6 are used to clamp the side wall of the pier column 19;

[0033] The utility model can connect the two clamps 6 in each group to form an integral clamp structure, which has stronger integrity than the traditional single independent clamp, increases the tightness and stability of the connection between adjacent clamps, and the effect of the clamp on the pier column is more stable.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
