Technical Field
The utility model relates to a pin is torn open in ann fast of tower crane standard festival belongs to construction technical field.
Background
The tower crane is a hoisting device which is commonly used in construction sites and is used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like for construction. Its gallows of tower crane is assembled by a plurality of standard festival and is piled up and form, and the contact surface between standard festival and the standard festival is the terminal surface of four main bearing angle steel, and the connection between tower crane standard festival generally adopts bolt and nut to fix, because it needs at least 8 between each standard festival of tower crane, needs 16 fixing bolt at most even, and this kind of method makes the installation process time overlength, consumes a large amount of manpowers, and is very big to workman's health burden. And because standard festival bolt installation quantity is many, and the installation of bolt nut needs electric spanner to fasten, installer often need spend a large amount of efforts in the installation of bolt and the fastening of nut, can avoid resulting in the condition that the nut does not lock because of the work negligence in the connection process to can add the multisection at the tower crane joining in-process, in order to improve the installation effectiveness, there is not the installation condition in the joining in-process, thereby harm master and slave's life safety.
SUMMERY OF THE UTILITY MODEL
In order to overcome current tower crane standard festival bolt fastening power consumption consuming time, shortcoming such as the installation effectiveness low, the utility model discloses a quick ann of tower crane standard festival tears pin open, its simple structure, the installation is dismantled conveniently, can reduce the time that constructor consumes in the installation in a large number.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a quick mounting and dismounting pin for a tower crane standard knot comprises a polished rod pin, a quick bolt and a fixing pin, wherein a pin hole which is matched with the quick bolt to be connected with a tower crane standard knot component is formed in the polished rod pin; the quick bolt is arranged in a trapezoid shape with gradually increasing width, and the size of the pin hole is smaller than the maximum width of the quick bolt; the quick bolt is provided with a fixing hole which is matched with the fixing pin and used for preventing the quick bolt from falling off when being matched with the polished rod pin; the quick bolt is provided with a guide groove along the direction in which the quick bolt is inserted into the pin hole, and the inner wall of the pin hole is provided with a guide convex block matched with the guide groove.
Further, the fixing pin is an R-shaped split pin.
Further, quick bolt is right trapezoid setting.
Furthermore, the fixing hole is arranged in the middle of one side, close to the short side, of the rapid bolt in the trapezoidal arrangement.
Further, when the quick bolt is inserted into the pin hole until the quick bolt can not be inserted any more, the guide projection just abuts against the end part of the guide groove.
Compared with the prior art the utility model discloses there are following characteristics and beneficial effect: the tower crane standard knot can be quickly connected through the arrangement of the quick bolt, meanwhile, the disassembly and the assembly are convenient and simple, the working efficiency is greatly improved, the installation time is reduced, a large amount of manpower is saved, the safety of the whole installation is ensured while the quick installation and the connection are realized, and the safety of a master worker and a master worker during construction is ensured; set up the guide way on quick bolt, can help the workman master to find the bolt position fast, improve the stability of quick bolt insertion pinhole in-process, prevent that quick bolt from inserting askewly.
