Brief description of the drawings
Fig. 1 is the schematic diagram of all parts of the present invention.
Fig. 2 is the schematic diagram after the present invention assembles.
In figure, be labeled as: upper rectangular tube 1, short fish plate knock hole 11, Changyu tailgate knock hole 12, lower rectangular tube 2, short fish plate through hole 21, short fish plate 211, Changyu tailgate through hole 22, Changyu tailgate 221, short fish plate latch 3, Changyu tailgate latch 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Tower crane rectangle fish plate structure as shown in Figure 1 and Figure 2, comprise rectangular tube 1, lower rectangular tube 2, Changyu tailgate latch 4 and short fish plate latch 3, on two relative tube walls of described upper rectangular tube 1, be provided with Changyu tailgate knock hole 12, on upper rectangular tube 1 two other relative tube wall, be provided with short fish plate knock hole 11;
On two relative tube walls of lower rectangular tube 2, be provided with Changyu tailgate 221, on described Changyu tailgate 221, be provided with Changyu tailgate through hole 22, on lower rectangular tube 2 two other relative tube walls, be provided with short fish plate 211, on described short fish plate 211, be provided with short fish plate through hole 21;
Described Changyu tailgate latch 4 is arranged in Changyu tailgate knock hole 12 and Changyu tailgate through hole 22, short fish plate latch 3 is arranged in short fish plate knock hole 11 and short fish plate through hole 21, and described upper rectangular tube 1 is connected with short fish plate latch 3 by described Changyu tailgate latch 4 with lower rectangular tube 2.
As shown in Figure 1, in the time that reality is used, only need very easily the Changyu tailgate knock hole 12 of upper rectangular tube 1 be alignd with the Changyu tailgate through hole 22 of lower rectangular tube 2, the short fish plate knock hole 11 of upper rectangular tube 1 is alignd with the short fish plate through hole 21 of lower rectangular tube 2 simultaneously, then Changyu tailgate latch 4 is arranged in Changyu tailgate knock hole 12 and Changyu tailgate through hole 22, short fish plate latch 3 is arranged in short fish plate knock hole 11 and short fish plate through hole 21.The axis of short fish plate latch 3 is now spatially crossing but not coplanar with the axis of Changyu tailgate latch 4, and be short fish plate 211 or Changyu tailgate 221 has all obtained good constraint, very firm bearing capacity is provided in the use procedure of the mechanism that can obtain at structure.Meanwhile, in the time that use finishes to dismantle, only need easily Changyu tailgate latch 4 and short fish plate latch 3 be taken out.Same, the present invention, in the time of actual fabrication, has benefited from the ingenious of its structure design, has also simplified greatly the operation of manufacturing.
For ensure each side stressed evenly, for the shape of upper rectangular tube 1, can select described upper rectangular tube 1 is square tube, is the upper rectangular tube 1 of square.Such convenience can well realize stressed distribution while no matter being subject to the application force of short fish plate knock hole 11 or the application force of Changyu tailgate knock hole 12, thereby thereby greatly reduces because the discontinuity that shape irregularity causes affects the situation in service life.Based on same thought, described lower rectangular tube 2 also can be chosen as square tube.
In order to ensure that slippage can not appear in Changyu tailgate latch 4 in use that be inserted into two Changyu tailgate knock holees 12, can select parallel with horizontal surface the hole line of centres of two Changyu tailgate knock holees 12 on described upper rectangular tube 1.As depicted in figs. 1 and 2, horizontally disposed Changyu tailgate latch 4 greatly reduces the risk of Changyu tailgate latch 4 slippages in use, makes structure more firm.Certain, also can select the hole line of centres of two short fish plate knock holees 11 on described upper rectangular tube 1 parallel with horizontal surface.
In the time of the tailgate 221 of processing Changyu, for the ease of manufacturing, can select two Changyu tailgates 221 of described lower rectangular tube 2 to be arranged in the outside wall surface of upper rectangular tube 1.As shown in Figure 1, two Changyu tailgates 221 are arranged to the manufacture difficulty having reduced greatly in the outside wall surface of upper rectangular tube 1 manufacturing time of the present invention, and in the time of practical set, being arranged at the outside wall surface that two Changyu tailgates 221 in lower rectangular tube 2 outside wall surface also can well go up rectangular tube 1 blocks, not only allow assembling simpler, also allow structure more firm.Based on same thought, also can select two short fish plates 211 of described lower rectangular tube 2 to be arranged in the outside wall surface of rectangular tube 1.
Make choosing of material for Changyu tailgate 221, preferably the material of Changyu tailgate 221 is Q345B or ZG25Mn2.Described Changyu tailgate 221 is intermediate materials of realizing the transmission of power between upper rectangular tube 1 and lower rectangular tube 2, and it is very high to stretch-proof and torsion proof requirement, and therefore preferred material is Q345B or ZG25Mn2.For with the similar short fish plate 211 of Changyu tailgate 221 environment for use, the material that also can select short fish plate 211 is Q345B or ZG25Mn2.
