Detailed Description
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that such embodiment(s) may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 shows a schematic structure of a bailey pin extracting apparatus according to an embodiment of the present invention, fig. 2 shows a sectional structure of the bailey pin extracting apparatus according to an embodiment of the present invention, fig. 3 is a schematic view of the bailey pin extracting apparatus according to an embodiment of the present invention connected to an electric drill, and fig. 4 shows an enlarged partial sectional structure of a sleeve according to an embodiment of the present invention.
As shown together with fig. 1 to 4, the bailey pin extraction device provided by the present invention comprises a screw rod 11 and a support frame 13 for supporting and stabilizing, specifically, the support frame 13 comprises a support plate 131 screwed on the screw rod 11 (i.e. the support plate 131 is rotatably connected with the screw rod 11 by a screw thread) and a cylindrical support arm 132 integrally formed with the support plate 131; wherein, the end of the screw rod 11 far away from the cylindrical support arm 132 is fixedly connected with the screw cap 12, and the end of the screw rod 11 near the cylindrical support arm 132 is provided with a clamp matched with the bailey pin 18 to be pulled out; the jig is housed inside the cylindrical support arm 132.
In the actual use process, the cylindrical support arm 132 needs to be abutted against the bailey beam section steel 19 near the bailey pin 18 to be pulled out, so that the cylindrical support arm 132 is positioned; then, locking and fixing the drawing opening of the bailey pin through a clamp; the screw cap 12 is rotated to drive the screw rod 11 to rotate (the rotation direction is determined according to actual conditions), at this time, because the screw thread connection relationship between the screw rod 11 and the supporting plate 131 and the abutting acting force relationship between the cylindrical supporting arm 132 and the bailey beam profile steel 19, the cylindrical supporting arm 132 will not rotate along with the screw rod 11, therefore, the screw rod 11 will move spirally upwards (away from the bailey beam) on the supporting frame 13, and along with the screw rod 11 away from the bailey beam, the clamp can be driven to extract the bailey pin from the pin hole of the bailey beam. The pulling-out of the bailey pin can be avoided, and the work efficiency can be obviously improved while the labor is saved.
Specifically, to realize that the clamp clamps the bailey pin, the clamp may include two clamping jaws 14 (or a plurality of clamping jaws, which are arranged at equal intervals) symmetrically arranged opposite to each other, an annular groove 151 (not shown in the figure) is formed at one end of the screw rod 11 close to the cylindrical support arm 132, a rotating ring 15 is hinged in the annular groove 151, and both the two clamping jaws 14 are rotatably connected with the rotating ring 15 through a hinge 142. By arranging the rotating ring 15 between the clamping jaw 14 and the screw rod 11, the clamping jaw 14 can rotate along with the screw rod 11, and the service life of the clamping jaw 14 is prolonged. In addition, the clamping jaw 14 is arranged to be rotatably connected with the rotating ring 15 through the hinge 142, so that the clamping jaw 14 can be opened and closed, and the clamping jaw 14 can clamp and fix the bailey pin.
In addition, in order to improve the clamping effect of the clamping jaw 14 on the bailey pin and prevent the clamping jaw 14 from being separated from the bailey pin in the pulling process, a clamping knife 141 matched with a pulling opening 181 on the bailey pin 18 to be pulled out is integrally formed at one end of each of the two clamping jaws 14, which is far away from the rotating ring 15, and in the using process, the clamping knife 141 is inserted into the pulling opening 181, so that the clamping and fixing of the clamping jaw 14 on the bailey pin can be realized.
In addition, for the bailey pin of the different diameters of clamping jaw 14 adaptation, the inner wall of two clamping jaws 14 all is the arc structure, because the inner wall of clamping jaw 14 is the arc structure, the outer wall that waits to extract bailey pin 18 also generally is the arc structure (waiting to extract bailey pin 18 diameter and clamping jaw 14's diameter is little), and the adaptation can be realized to the inner wall of arc structure and the outer wall of arc structure.
It should be noted that, because the clamp is disposed inside the tubular supporting arm 132, in order to facilitate the clamp and the bailey pin to be clamped and fixed manually, an operation opening 133 corresponding to the position of the clamp may be formed on the side wall of the tubular supporting arm 132, and in the actual operation process, the clamp and the bailey pin are clamped and fixed by inserting a hand into the tubular supporting arm 132 through the operation opening 133.
In addition, in order to further improve the working efficiency, an adjusting hole 121 may be formed in the screw cap 12, and in the actual use process, the steel bar is inserted into the adjusting hole 121, and the screw rod 11 can be driven to rotate by turning the steel bar.
Of course, the sleeve 16 may be sleeved on the screw cap 12, and a rotating shaft 161 adapted to the chuck of the external electric drill 17 may be integrally formed at an end of the sleeve 16 away from the screw rod 11. In practical use, the electric drill 17 connected to the screw cap 12 via the rotating shaft 161 in advance is started to rotate the screw rod 11.
It should be noted that, in order to ensure the synchronous movement of the screw cap 12 and the sleeve 16, the screw cap 12 has a square structure, the inner cavity of the sleeve 16 has a square structure corresponding to the shape of the screw cap 12, and the screw cap 12 is synchronous with the sleeve 16 through the square structure. Of course, the inner cavities of the screw cap 12 and the sleeve 16 are not limited to a square structure, such as a triangular prism structure, as long as the corresponding fitting relationship is satisfied, and the screw cap 12 and the sleeve 16 move synchronously.
In addition, based on the structure of the bailey pin pulling-out device, the invention also provides a bailey pin pulling-out method, which is used for pulling out the bailey pin by using the bailey pin pulling-out device; the method comprises the following steps:
