Description
Technical field
The utility model relates to a kind of fixed form of jib carrier pipe support, also relates to the boom with this fixing means simultaneously.
Background technology
Jib carrier pipe, for concrete conveying and cloth, is connected with jib structure by support, is the important component part of boom.The concrete feeding style processes that adopt two material cylinders alternately " to inhale-tell-inhale ", and also correspondingly commutation repeatedly of valve (domestic most S valves that adopt) in hopper more, this just causes jib carrier pipe will inevitably occur pulse shock and shake; Simultaneously, accumulation along with pump time, carrier pipe is by attenuation gradually, and domestic concrete quality is uneven, when there is " plugging " phenomenon, " booster " phenomenon of carrier pipe will be there will be, and the appearance meeting of " booster " causes king-sized impact force near carrier pipe support, even fracture failure.Therefore be mainly flexible, shock-resistant to the requirement of carrier pipe support; Meanwhile, convenient for maintaining is changed, particularly at the simple and crude building-site of condition of work.
At present, the support of jib carrier pipe mainly contains two kinds of fixed forms, sees Figure 1A to Figure 1B and Fig. 2 A to Fig. 2 B.
Figure 1A to Figure 1B is shown as the fixed form schematic diagram of existing a kind of typical jib carrier pipe support, and wherein Figure 1A is design sketch, and Figure 1B is explosive view.As shown in the figure, according to the position of carrier pipe, carrier pipe supporting structure 12 completes and self connects after (welding or assembling), is through in jib structure 11 installing holes, and junction adopts welding manner to connect.
Fig. 2 A to Fig. 2 B is shown as the fixed form schematic diagram of the common jib carrier pipe support of existing another kind, and wherein Fig. 2 A is design sketch, and Fig. 2 B is explosive view.As shown in the figure, pipe 212 is welded into after integral body with junction plate 213, is welded to connect into it integral body 21, and keeps overhanging of certain length through jib frame type structure 211 installing holes.According to the position of carrier pipe, carrier pipe supporting structure 22 is connected with junction plate 213 by bolt 23, nut 24.
Be not difficult to find out, two kinds of common jib carrier pipe support fixed forms have very large deficiency.Jib carrier pipe support in Fig. 1 and Fig. 2 is all welded to connect with jib structure, has overhanging of certain length simultaneously.This just causes: when carrier pipe support is subject to very large external impacts or fatigue failure and occurs crack conditions, the position of fracture is concentrated in support and jib structure junction, in Fig. 1, in carrier pipe supporting structure 12 and jib structure 11 junctions (near carrier pipe one side) and Fig. 2, manages 212 and jib frame type structure 211 junctions (close carrier pipe one side).Visible, the fixed form showing in Fig. 1 and Fig. 2 can make jib carrier pipe support replace workload large, and need carry out welding job, and, bad if welding parameter is controlled, may have a huge impact critical component jib framework.
Summary of the invention
The technical problems to be solved in the utility model is to reduce the workload of jib carrier pipe support replace.
In order to achieve the above object, a technical scheme of the present utility model has been to provide a kind of jib carrier pipe support fixed structure, it is characterized in that: comprise on a cant board of carrier pipe support to be installed and open round-meshed jib framework, the stiffener that has endoporus is welded on jib framework and opens on round-meshed this cant board, circular hole arranged concentric on endoporus on stiffener and jib framework, pipe passes endoporus and becomes jib structure with stiffener and jib frame welding after circular hole, carrier pipe supporting plate is bolted on stiffener, the carrier pipe stand tube of having good positioning according to jib carrier pipe position is welded to connect into carrier pipe support with carrier pipe supporting plate.
Another technical scheme of the present utility model has been to provide a kind of boom that adopts above-mentioned jib carrier pipe support fixed structure, it is characterized in that, at least comprise jib carrier pipe, described jib structure and described carrier pipe support, jib carrier pipe is connected with described jib structure by described carrier pipe support.
In the fixed structure that this utility model provides, the arm support position of carrier pipe support to be installed increases stiffener, and adds and on stiffener, process screwed hole man-hour at jib.Carrier pipe support one end connecting conveying pipe, the other end is directly connected on jib with bolt.Because the stiffener on jib is tightly connected with jib body, the power of carrier pipe support will pass to whole jib structure by jib stiffener.Under the enough prerequisite of bolt strength, when carrier pipe support is subject to large external force and occurs fracture failure, fracture position is the root at carrier pipe support, i.e. carrier pipe support self.Thus, change carrier pipe support, only need to remove the carrier pipe support also more renewing, do not need jib structure to carry out any operation, particularly welding job, thereby can not cause damage to jib structure.
Therefore, the utlity model has following technique effect: can simplify jib carrier pipe support maintenance load, efficiency is high, maintenance process is to not damage of jib structure.

Figure 1B is the explosive view of Figure 1A;
Fig. 2 A is the design sketch of the fixed form of another kind of typical jib carrier pipe support;
Fig. 2 B is the explosive view of Fig. 2 A;

The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Fig. 3 A and Fig. 3 B, a kind of jib carrier pipe support fixed structure that the utility model provides comprises jib framework 311, jib framework 311 has circular hole in the riser position of carrier pipe support to be installed, stiffener 313 is welded on (near carrier pipe one side) on jib framework 311 risers, and keeps stiffener 313 endoporus concentric with jib framework 311 riser endoporus.Pipe 312 passes the riser of stiffener 313 and jib framework 311, and is welded into jib structure 31 with it.
After carrier pipe supporting plate 321 is connected on stiffener 313 by bolt 33, the carrier pipe stand tube 322 of having good positioning according to carrier pipe position is welded to connect into carrier pipe support 32 with carrier pipe supporting plate 321.
The power that carrier pipe support is subject to will and then reasonably pass to jib framework 311 by bolt 33, stiffener 313, pipe 312.
When if jib carrier pipe or carrier pipe support are subject to exceeding the impact of self-bearing capacity, the position of fracture will appear on carrier pipe support 32, and jib structure 31 is not had to larger infringement; And replacing or reparation carrier pipe support 32 are very convenient, can not produce any infringement to jib structure.
The boom that adopts above-mentioned jib carrier pipe support fixed structure, at least comprises jib carrier pipe, jib structure 31 and carrier pipe support 32, and jib carrier pipe is connected with described jib structure 31 by described carrier pipe support 32.
