Specific implementation mode
The stock-removing machine to the precast concrete tower section of the embodiment of the present invention and cutting process carry out detailed below in conjunction with the accompanying drawings
Thin description.
Embodiment one
As depicted in figs. 1 and 2, be respectively the embodiment of the present invention one precast concrete tower section stock-removing machine first
Kind working state figure and second of working state figure.The stock-removing machine of the precast concrete tower section of the present embodiment comprising be used for
The rotary table 2 for carrying precast concrete tower section 1 is equipped with the support construction 31 of fixed setting in the side of rotary table 2,
It is equipped with the suspended structure 32 for the top for extending to rotary table 2 in support construction 31, is equipped with and is used in suspended structure 32
The abrasive machine 4 that the end face of precast concrete tower section 1 is ground.
The stock-removing machine of precast concrete tower section provided in this embodiment is carried by rotary table 2 and is driven pre-
Concrete tower segment 1 processed rotates, while precast concrete tower section 1 rotates, by the way that the grinding wheel above rotary table 2 is arranged
Machine 4 is ground the end face of precast concrete tower section 1, and alternative existing polishing mode reduces the labor intensity of worker, protects
Hinder the flatness of the end face of precast concrete tower section 1, improve the quality of precast concrete tower section 1, there is reliability height, processing to hold
It easily realizes, feature at low cost.Specifically, precast concrete tower section 1 is ground in the stock-removing machine using the present embodiment
When, it can first be polished the current end face upward of precast concrete tower section 1 (referring to Fig. 1), it, can behind the end face of having polished
Precast concrete tower section 1 is upside down on rotary table 2, so that original end face directed downwardly is become current end face upward, then
Again polished end face currently upward (referring to Fig. 2).
Flatness processing is carried out by the upper and lower end face (faying face) to precast concrete tower section 1, can subsequently built
Reduce the centre-to-centre spacing offset of whole tower when precast concrete tower, the assembly precision of precast concrete tower section 1 is improved, to improve
The total quality of pylon mitigates assembly work amount, reduces the difficulty in on-site hoisting, assembling process and the labor of Field Force to the greatest extent
Fatigue resistance improves production efficiency, realizes product low cost operation.
Specifically, support construction 31 and suspended structure 32 can be concrete building structures as shown in the figure, can also be
Steel construction.And precast concrete tower section 1 can be in truncated cones tubular as shown in the figure, can also be in cylinder barrel shaped.
Although there is frictional force, in order to ensure to carry out polishing work between precast concrete tower section 1 and rotary table 2
When industry, precast concrete tower section 1 will not be moved relative to rotary table 2, in the present embodiment further on rotary table 2
It is fixed with the clamping device 5 for clamping precast concrete tower section 1, it is right by the clamping device 5 being fixed on rotary table 2
Precast concrete tower section 1 is clamped, and can prevent precast concrete tower section 1 from being moved relative to rotary table 2, ensures polishing
Operation is smoothed out.
The case where for precast concrete tower section 1 in the present embodiment being in truncated cones tubular, the clamping dress in the present embodiment
5 are set with the matched inclined-plane of side wall (not marked in figure) with precast concrete tower section 1, when the inclined-plane compresses precast concrete
Downward component can be generated when tower section 1 to precast concrete tower section 1, to ensure precast concrete tower section 1 relative to revolution work
Make the fixation of platform 2.Due to there are two types of modes of emplacement of the precast concrete tower section 1 on rotary table 2, so corresponding clamping side
Formula also there are two types of.Fig. 1 shows the feelings when smaller diameter end (the smaller one end of diameter) of precast concrete tower section 1 is arranged upward
Shape, under such situation, clamping device 5 is located at the outside of precast concrete tower section 1, the inclined-plane and precast concrete of clamping device 5
The lateral wall of tower section 1 fits.Fig. 2 shows the larger diameter ends of precast concrete tower section 1 (one end of diameter bigger) to set upward
Situation when setting, under such situation, clamping device 5 is located at the inside of precast concrete tower section 1, the inclined-plane of clamping device 5 with it is pre-
The madial wall of concrete tower segment 1 processed fits.Both clamping modes can utilize the taper of precast concrete tower section 1 to pre-
Concrete tower segment 1 processed generates downward component, and precast concrete tower section 1 is pressed to rotary table 2, ensures precast concrete tower
Section 1 is fixed relative to rotary table 2.
As long as clamping device 5, which reaches, pushes against precast concrete tower section 1, it is made to be fixed relative to rotary table 2, because
The structure design of this clamping device 5 can have larger flexibility.Specifically, the clamping device 5 in the present embodiment includes rib
51 and pressing plate 52, rib 51 be fixed on rotary table 2, the inclined-plane of clamping device 5 said before is arranged in pressing plate 52
One end, the other end and the rib 51 of pressing plate 52 offset, and only needing simply to push pressing plate 52 in this way to reach makes pressing plate 52
The purpose of precast concrete tower section 1 is pushed against, operation is relatively simple, because when applying downward pressure to pressing plate 52, pressing plate 52
Have the tendency that moving downward, and the distance between rib 51 and precast concrete tower section 1 are to tend to become smaller along downwardly direction
, such pressing plate 52 will hold out against precast concrete tower section 1, meanwhile, the inclined-plane on pressing plate 52 also can be to precast concrete tower section 1
Generate downward component.Preferably, the number of pressing plate 52 can be multiple, and height of the multiple pressing plates 52 on rib 51 is different,
The different pressing plate 52 of height multiple in this way can form Multilayer clamping structure, respectively to precast concrete tower section in multiple height
1 is clamped, and is more uniformly distributed to the clamping of precast concrete tower section 1, also relatively reliable.
Front carries out the structure and application method of the stock-removing machine of the precast concrete tower section of the embodiment of the present invention one
Illustrate, the cutting process of the precast concrete tower section of the embodiment of the present invention two is illustrated below, it, can when reading this method
With the attached drawing before referring also to.
