DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings. The structure and principle of the present invention will be very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0024] Figure 1 This is a front view of an embodiment of a large-diameter steel bar 7 sleeve connection, lifting and extension device of the present application. Figure 2 for Figure 1 Left side view of the embodiment shown, Figure 3 for Figure 1 Bottom view of the embodiment shown. Figure 1 、 Figure 2 and Figure 3 The device may include a square steel hanging beam 3, a limiting square steel 4, an upper connecting sleeve 6 and a lower connecting sleeve 9. The left and right ends of the square steel hanging beam 3 are open, and a number of vertical grooves 12 with openings on one side of the front or rear are evenly spaced on the square steel hanging beam 3. The limiting square steel 4 enters from the opening at the left or right end of the square steel hanging beam 3, is arranged close to the opening side of the vertical groove 12, and passes through all the vertical grooves 12. One or more steel bars 7 are arranged in the vertical groove 12, and the top end of the steel bar 7 is connected and fixed to the upper connecting sleeve 6 on the upper side of the vertical groove 12, and the bottom end of the steel bar 7 is connected to the lower connecting steel bar 14 through the lower connecting sleeve 9.

[0025] The two ends of the limiting square steel 4 are respectively provided with a first limiting part and a second limiting part for limiting the sliding of the limiting square steel 4. The top surface of the square steel lifting beam 3 is symmetrically provided with a lifting lug 2 for connecting a lifting device.

[0026] When the large-diameter steel bar sleeve connection lifting and extension device is used to lift the steel bar 7, the top end of the steel bar 7 is installed on the upper connecting sleeve 6, and the bottom end passes through the vertical groove 12 so that the steel bar 7 is embedded in the vertical groove 12. The limiting square steel 4 seals the steel bar 7 in the groove to limit the steel bar 7. It should be noted that the width of the groove of the present application is larger than the inner diameter of the steel bar 7 to be lifted, and the inner diameter of the upper connecting sleeve 6 is adjustable to meet the needs of lifting large-diameter steel bars.

[0027] Both ends of the retaining square steel 4 extend out of the square steel hanging beam 3. The first retaining portion is a downwardly bent anti-slip hook 5, formed by bending one end of the retaining square steel 4 downward. The second retaining portion is a T-shaped anti-slip pin 10, which consists of a cap and a body. The cap is mounted on the top surface of the retaining square steel 4, and the body passes through the retaining square steel 4 through a bolt hole 13 and extends out of the bottom surface of the retaining square steel 4. The cap is connected to the retaining square steel 4 via a wire 11. Straight threads 8 surround the top and bottom ends of the reinforcement bar, which are used to attach the reinforcement bar 7 to the upper and lower connecting sleeves 6 and 9.

[0028] Specifically, the present invention provides a large diameter steel bar 7 sleeve connection lifting and extension device which can be composed of a first component and a second component. Figure 4 This is the main view of the first component of this application, Figure 5 is the left view of the first component, Figure 6 is a bottom view of the first component, Figure 7 This is a schematic structural diagram of the second component of this application.

[0029] Combine Figures 4 to 7It can be understood that the first component is placed flat on the installation platform, and the steel bar 7 with one end connected to the upper connecting sleeve 6 is installed in the vertical groove 12. After the steel bar 7 is installed, the second component is inserted to prevent the steel bar 7 from falling off. A bent hook is set on one side of the limiting square steel 4 to prevent it from falling off, and a T-shaped anti-falling pin 10 is set on the other side to prevent it from slipping. In order to prevent the T-shaped anti-falling pin 10 from being lost, the T-shaped anti-falling pin 10 is connected to the limiting square steel 4 with a wire 11 to ensure safety. After the limiting square steel 4 is installed, the wire rope 1 is inserted into the lifting ear 2 to lift it, and it is suspended above the steel bar 7 to be connected. Workers can find the best connection position by moving the steel bar 7 up and down. After connecting the steel bar 7, the square steel beam 3 is slowly lowered. After reaching the height that workers can operate, the limiting square steel 4 is pulled out to remove the steel beam, and the next cycle of construction is repeated.
