The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
A kind of dismountable tower crane, as depicted in figs. 1 and 2, including four support tubes 1, support tube 1 are in charge of by more
2 connections are formed, and the bindiny mechanism for connecting two support tubes 1 is equipped between adjacent supports pipe 1.Bindiny mechanism includes fixed connects
The horizontally disposed connecting rod 3 and brace 4 being connected on two support tubes 1, connecting rod 3 and brace 4 pass through bolt and branch
Stay tube 1 connects.1 bottom of support tube is equipped with discharge hole 5, and 1 bottom of support tube is fixed with steel reinforcement cage 6.By past above tower crane
Mortar is poured into support tube 1, mortar is flowed out by discharge hole 5 and the solidification in steel reinforcement cage 6, is reinforced to tower crane.
The one end for being in charge of 2 is equipped with convex pipe 7, and the other end for being in charge of 2 is rotatably connected to the sheath body 8 being inserted into for convex pipe 7, convex pipe 7
On be fixed with drive block 9,8 inner wall of sheath body is equipped with the guide groove 10 slide for drive block 9, be in charge of 2 inner wall equipped with
The sliding slot 11 that guide groove 10 is connected to, sliding slot 11 sheath body 8 and are in charge of at 2 rotation connections and are equipped with torsional spring in horizontally disposed（Do not show in figure
Meaning）.When being in charge of 2 connection for two, the convex pipe 7 that one of them can be in charge of to 2 ends is inserted into another sheath body 8 being in charge of on 2,
During insertion, drive block 9 is inserted into guide groove 10, during convex pipe 7 is inwardly moved along sheath body 8,
Under the action of guide groove 10, sheath body 8 rotates, when drive block 9 reaches in sliding slot 11, work of the sheath body 8 in torsional spring restoring force
With lower rotation, drive block 9 slides into sliding slot 11, and drive block 9 can not edge under the clamping effect of 11 inner wall of sliding slot at this time
It is in charge of 2 length direction movement, having reached two and being in charge of 2 and can not slip away along its length makes effect easier for installation
Fruit.
The end for being in charge of 2 is equipped with pipe 12, and being equipped in pipe 12 makes two to be in charge of the first bolt 13 that 2 are connected and fixed and the
One nut 14, the first bolt 13 pass through two pipes 12 being in charge of on 2 and are threadedly coupled with the first nut 14.Pass through the first bolt
13 and first nut 14 can be in charge of 2 fixations by two, keep the connection for being in charge of 2 more secured.
The quantity of drive block 9 and guide groove 10 is two, and two guide grooves 10 are symmetrical arranged, and pass through two drive blocks 9
With the cooperation of two guide grooves 10, then drive block 9 is more stable when sliding in guide groove 10, and sheath body 8 is more uniformly stressed.
Guide groove 10 is equipped with close to 8 end of sheath body along the vertical slot 15 for being in charge of the setting of 2 length directions, in the process of installation
In, drive block 9 is entered first along vertical slot 15 in sheath body 8, then during drive block 9 is inserted into sheath body 8, Bu Huiyou
In drive block 9, when entering in guide groove 10, sheath body 8 rotates and causes to be difficult to ensure that two drive blocks 9 enter guiding
In slot 10.
Line between 10 disjoint two ends of sliding slot 11 and guide groove is parallel with the length direction of sheath body 8, then when
Sheath body 8 is rotated under the action of torsional spring restoring force after so that drive block 9 is entered in sliding slot 11, and drive block 9 reaches the end of sliding slot 11
Portion, at this time torsional spring be in former long status, torsional spring is less likely to occur to damage.
When drive block 9 is located in sliding slot 11, it is in charge of 2 end faces close to one end of convex pipe 7 and another sheath body being in charge of on 2
8 end face abuts, then is in charge of 2 and is combined in connection even closer for two, and can share drive block 9 and 11 junction of sliding slot
Stress, make drive block 9 be not susceptible to damage.
The inner wall of convex pipe 7 is flushed with the inner wall for being in charge of 2, then when pouring into mortar in support tube 1, mortar is not easy to remain
Cause to block in support tube 1 with the junction of being in charge of 2 in convex pipe 7.
Specific work process：During installation, the convex pipe 7 that one of them is in charge of to 2 first is inserted into another point
In the sheath body 8 of pipe 2, the drive block 9 on convex pipe 7 slides into along the vertical slot 15 on 8 inner wall of sheath body in guide groove 10, in drive block
9 under the cooperation of guide groove 10, and when drive block 9 is slided along guide groove 10, sheath body 8 rotates, when drive block 9 moves to
When sliding slot 11 is with 10 junction of guide groove, sheath body 8 rotates under the action of torsional spring restoring force, and drive block 9 reaches sliding slot 11
End.It is in charge of 2 at this time to abut with another sheath body 8 being in charge of on 2 close to one end of convex pipe 7, while two pipes being in charge of on 2
12 are in corresponding states, pass through two pipes 12 being in charge of on 2 using the first bolt 13 and are threadedly coupled with the first nut 14, will
It is in charge of 2 for two to be connected and fixed, repeats this operation and all 2 connections of being in charge of are formed into support tube 1, finally recycle 3 He of connecting rod
Multiple support tubes 1 are attached fixation by brace 4, and after completing installation, mortar is poured into along support tube 1, and mortar is from discharge hole 5
Steel reinforcement cage 6 is flowed out to, tower crane is reinforced.
