Abstract
It is a kind of to be used for the mobile protective frame that topples of crane when Urban Metro Construction, to effectively improve the safety of Urban Metro Construction, crane is reduced to greatest extent and is toppled the damage caused by holdee's vehicle.Including protection steelframe and temporary fastening device, the bottom of steelframe is protected vertically and horizontally to be spaced setting wheel；Temporary fastening device is set to protection steelframe bottom four corners, is formed by being fixed temporarily steel plate and elevating mechanism.
Description
Technical field
The utility model is related to Urban Metro Construction equipments, more particularly to crane topples when one kind being used for Urban Metro Construction
Mobile protective frame.
Background technology
The High Speed Construction phase of all parts of the country subway market access at present, and to construct be mostly personnel's vehicle close quarters, construction
Narrow field, enclosing is generally close to major urban arterial highway, when automobile crane operation, inevitably there is the risk toppled, for maximum
The reduction of limit is damaged caused by holdee's vehicle, needs to topple protective frame provided with a kind of packaged type crane.
Utility model content
The shifting that crane topples when the technical problem to be solved by the utility model is to provide a kind of for Urban Metro Construction
Dynamic formula protective frame reduces crane and topples to holdee's vehicle to greatest extent to effectively improve the safety of Urban Metro Construction
Damage caused by.
Technical solution is as follows used by the utility model solves its technical problem：
The a kind of of the utility model is used for the mobile protective frame that topples of crane when Urban Metro Construction, it is characterized in that：Packet
Protection steelframe and temporary fastening device are included, the bottom of steelframe is protected vertically and horizontally to be spaced setting wheel；Temporary fastening device is set to
Steelframe bottom four corners are protected, are formed by being fixed temporarily steel plate and elevating mechanism.
The utility model has the beneficial effects that it is rationally reliable, it is easy to use, densely populated place area can be reduced to greatest extent
Crane topples and is damaged caused by holdee's vehicle when the subway work of domain, effectively improves the safety of Urban Metro Construction.
Description of the drawings
This specification includes following three width attached drawing：
Fig. 1 be the utility model it is a kind of for Urban Metro Construction when the vertical view of mobile protective frame that topples of crane；
Fig. 2 be the utility model it is a kind of for Urban Metro Construction when the cross-section diagram of mobile protective frame toppled of crane；
Fig. 3 be the utility model it is a kind of for Urban Metro Construction when the mobile protective frame that topples of crane in fixation steel plate
Plan view；
Component and corresponding label are shown in figure：Protection framework 10, wheel 11 are fixed temporarily steel plate 12, screw rod 13.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Figures 1 and 2, a kind of of the utility model is used for the mobile protective that topples of crane when Urban Metro Construction
The bottom of frame, including protection steelframe 10 and temporary fastening device, protection steelframe 10 is vertically and horizontally spaced setting wheel 11.It is fixed temporarily
Device is set to protection 10 bottom four corners of steelframe, is formed by being fixed temporarily steel plate 12 and elevating mechanism.When crane operation, it will protect
Steelframe 10 is moved to crane operation point, is placed close to major urban arterial highway enclosing side.Make to be fixed temporarily steel plate by elevating mechanism
12 drop to ground, and expansion bolt is then installed between ground is fixed temporarily steel plate 12 and is fixed temporarily protection steelframe 10.Crane
When toppling, protection steelframe 10 provides support for crane large arm, avoids the damage to social personnel and vehicle to the greatest extent.Lifting
After the completion of operation, expansion bolt is removed, rise is fixed temporarily steel plate 12 and disengages it from ground, and steelframe will be protected by wheel 11
10 are moved to subsequent work point.
Referring to Figures 1 and 2, the protection steelframe 10 is the Spatial infrastructure being welded by double I-steel, anti-to ensure
Protect the intensity of steelframe 10.The height of the other side is butted on close to the high bottom of operation lifting operation side.The elevating mechanism usually by
Screw rod 13, nut are constituted, and nut-welding is fixed on protection steelframe 10, and the lower end of screw rod 13 is welded with steel plate 12 is fixed temporarily.
It is described to be fixed temporarily in 12 plate face of steel plate vertically and horizontally interval setting mounting hole, it is formed across expansion bolt and the ground of each mounting hole
It is fixed temporarily connection.
Some principles of the utility model described above that only explains through diagrams, are not intended to the utility model being confined to
In shown and described concrete structure and the scope of application, therefore every corresponding modification for being possible to be utilized and equivalent,
Belong to the apllied the scope of the claims of the utility model.
