Abstract
The utility model discloses a standard knot coupling sleeve stop device of a tower crane, and relates to the technical field of construction machinery. Main branches of standard knots are provided with an upper coupling sleeve and a lower coupling sleeve; two adjacent standard knots are connected by a bolt through the upper coupling sleeve and the lower coupling sleeve; and a boss is arranged at the upper end of the lower coupling sleeve. The bolt is inserted into the upper coupling sleeve when the standard knots of the tower crane are arranged; a rotating high-strength hexagon bolt is baffled by the boss on the upper coupling sleeve when a person screws the nut by a spanner, so as to play a stopping role. The bolt is dismantled by the same method in a dismantling process. The high-strength bolt can be rapidly arranged without other tools and manpower; and the standard knot coupling sleeve stop device of the tower crane is simple in structure, applicable, safe and reliable.
Description
Technical field
The utility model relates to the vehicle for construction technical field, is specifically to play the parts of connection function on a kind of tower crane by bolt the coupling sleeve stop motion mechanism that the process of especially installing, dismantling at bolt plays the role of stopper.
Background technology
Tower crane is widely used in each big-and-middle-sized building ground as the machinery of the transportation of middle and high layer housing construction and equipment installation.Its tower body is partly to be formed by connecting by the high strength bolt that is contained in coupling sleeve by base section, reinforcement joint, standard knot, and the installation and removal of bolt are very important links.In prior art, the installation and removal process of bolt generally has two installation personnels to go up tower crane simultaneously to operate, and the human spanner nut that puts bolt that is fixedly connected prevents its rotation, and another people is at coupling sleeve lower end spanner clamp nut, otherwise nut can't be tightened.So not only increase labour cost, return erection work and bring certain potential safety hazard.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of tower crane mark
Accurate joint coupling sleeve stop motion mechanism is to realize the purpose of single independent installation or removal.
For achieving the above object, the master of standard knot of the present utility model props up and is provided with first line of a couplet female connector and second line of a couplet female connector, and adjacent two standard knots are connected bolt and are connected with lower link by first line of a couplet female connector, and it is characterized in that: the upper end of lower joint sleeve is provided with boss.
When column crane mast section was installed, bolt inserted second line of a couplet female connector, and during a human spanner fastening nut, the high strength hexagonal bar iron that thereupon rotates is kept out by the stop ledge that lower link puts, thereby played the effect of stop.During dismounting, disassemble bolt by same method and get final product.
The utility model compared with prior art, can Fast Installation high strength bolt, and need to be by other instrument, manpower, simple in structure applicable, safe and reliable.
Description of drawings
Fig. 1 is standard knot integral installation schematic diagram of the present utility model.
Fig. 2 is the I-I enlarged drawing of Fig. 1.
Fig. 3 is that the A of Fig. 2 is to view.
Fig. 4 is the B-B cutaway view of Fig. 3.
The specific embodiment
As shown in Figure 1, tower body is to be assembled by several standard knots 1, all adopts 8 10.9 grades, the high strength bolt of M30 to connect between every two standard knots 1 and tightens up, and sequence number 2 is propped up for the master of standard knot 1.
As shown in Figure 2, Figure 3, Figure 4, Fig. 2 is the I-I enlarged drawing of Fig. 1.The master of standard knot props up and is provided with first line of a couplet female connector 4 and second line of a couplet female connector 3, and adjacent two standard knots 1 are connected with second line of a couplet female connector with bolt 5 connections by first line of a couplet female connector 4, and the upper end of lower joint sleeve 3 is provided with boss 6.
When column crane mast section was installed, high strength bolt 5 inserted second line of a couplet female connectors 3, and boss 6 is wherein parallel on one side with high strength hexagonal bar iron 5, also can guarantee certain gap during bolt 5 and boss 6 nearest, can not interfere.When installation, dismounting, a human spanner fastening nut, the hexagonal bar iron 5 that thereupon rotates is kept out by the boss 6 on second line of a couplet female connector 3, thereby reaches the purpose of stop.
