The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.
Examples
Referring to fig. 1 and 2, an embodiment of the present invention provides a dismounting tool for a creeping formwork bearing pin, which is used for dismounting the bearing pin, and is more convenient and faster to use compared with the conventional tool in the prior art, specifically as follows.
The stripping tool for the climbing formwork bearing pin comprises a holding part 10 and a main body 20, wherein the main body 20 is of a columnar structure, preferably a cylinder shape, and at least the part connected with the holding part 10 is of the cylinder shape. Both ends of main part 20 all are provided with the butt piece 21 that matches with the bearing pin, and the one end of controlling 10 is provided with cyclic annular joint spare 11, and the intermediate position of main part 20 is located to the mobilizable cover of joint spare 11, and joint spare 11 is used for making main part 20 rotate along clockwise.
It should be noted here that the bearing pin is the same as a common nut in terms of use principle, but the bearing pin is longer and thicker, and the bearing pin can be gradually sleeved into the screw rod when installed, and can be gradually separated from the screw rod when rotating in the counterclockwise direction, and after the main body 20 is connected with the bearing pin, the bearing pin can be screwed down by rotating in the clockwise direction, otherwise, the bearing pin can be unscrewed.
Referring to fig. 3, in the present embodiment, an annular groove 12 is formed in the middle of the main body 20, the depth of each portion of the annular groove 12 is the same, that is, the middle of the main body 20 is also a cylindrical structure, a clamping groove 120 is formed in the bottom of the annular groove 12, the clamping groove 120 includes an abutting portion 121 and an attaching portion 122, one end of the clamping groove 120, which is close to the abutting portion 121, is arc-shaped, a blocking piece 123 which is engaged with the clamping groove 120 is rotatably disposed in the clamping groove 120, the blocking piece 123 has a first state which is connected with the attaching portion 122 and a second state which is connected with the abutting portion 121, a plurality of stopping blocks 110 are disposed at equal intervals in the inner ring of the clamping member 11, the stopping blocks 110 are used for abutting against the abutting portion 121 which is in the second state, and the clamping member 11 can. Also, the blocking piece 123 is equivalent to a portion dug out from the inside of the locking groove 120, and can be restored to the original position under the action of external force, so that the locking member 11 can rotate around the main body 20, and the state at this time is the first state. When the main body 20 needs to rotate, the blocking piece 123 is separated from the attaching portion 122 and abuts against the abutting portion 121, at this time, the stopper 110 on the inner ring of the clip member 11 just abuts against the other side of the blocking piece 123, and when the clip member 11 is twisted under the action of the holding member 10, the torsion is transmitted to the main body 20 through the blocking piece 123, so that the main body 20 rotates.
In this embodiment, an elastic member 124 is further disposed in the slot 120, one end of the elastic member 124 is connected to the attaching portion 122, the other end of the elastic member 124 is connected to the blocking piece 123, and the elastic member 124 always tends to make the blocking piece 123 away from the attaching portion 122. The elastic member 124 is a spring, or other elastic structure, which is used to pop the blocking plate 123, because the part where the bearing pin is installed is usually blocked by other structures, when the holding member 10 rotates to a certain angle, it will be blocked, the prior art will remove the whole detaching device from the bearing pin, return to the initial position and then screw the bearing pin at a certain angle, and go back and forth, the efficiency will be very low, and the device can continue to screw at a rotation angle on the premise of keeping the bearing pin from separating after the holding member 10 is screwed to a certain angle, which is very convenient and fast to use.
In this embodiment, one end of the bearing pin is provided with at least two slots, the abutting member 21 includes at least two protrusions 210 matching with the slots, and the protrusions 210 are used for being inserted into the slots and connecting the bearing pin and the main body 20 into a whole. Of course, the projection 210 and the contact member 21 are arranged oppositely, and the contact member 21 is mainly arranged according to the connection structure of the bearing pin, so long as the bearing pin and the contact member 21 are fixedly connected.
In this embodiment, the tool for detaching the bearing pin of the climbing formwork further includes a screwing handle 30, the screwing handle 30 includes a holding portion 31 and a connecting portion 32, the connecting holes 22 are formed at both ends of the main body 20, the connecting portion 32 is movably inserted into the connecting holes 22 and fixed, the bearing pin can be quickly screwed into the screw by screwing the handle 30 after the bearing pin is just screwed into the screw, and when the screwing handle 30 cannot screw the bearing pin, the holding member 10 is used to completely screw the bearing pin.
The bearing pin can be screwed at both ends of the main body 20 of the device, wherein one end of the bearing pin is used for screwing the bearing pin, and the other end of the bearing pin is used for unscrewing the bearing pin. And this device is provided with and screws out handle 30 and activity handle, installs at the top when screwing out handle 30 and using, can screw out the bearing round pin to certain tightness fast, then screws out it with the activity handle, and the effect of activity handle is, makes this extracting tool under the prerequisite of being connected with the bearing round pin all the time, and continuous twisting is moved to the bearing round pin, has improved production efficiency greatly.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
