Abstract
The utility model relates to a main-valve shield comprising a shield body that is arranged above a main valve and fixed inside a rotary table and particularly fixed on a cross beam, corresponding to the main valve above, inside the rotary table. The shield body comprises a shield part and a mounting part, the shield part covers all connectors on the upper side of the main valve from above, and the mounting part is provided with mounting holes, and is connected with threaded holes in the cross beam of the rotary table through bolts. The shield part comprises a flat plate and a bending plate; the bending plate is welded to the flat plate vertically, and the bending plate is abutted against one side of the cross beam of the rotary table. The mounting part and the flat plate are manufactured integrally. The shield is arranged above the main valve to protect the same effectively and can prevent the main valve from being polluted by rainwater, dust and the like outside.
Description
Technical field
The utility model relates to engineering machinery field, relates in particular to a kind of main valve safety cover.
Background technique
Crawler belt lifting turntable connects the key structure part of getting on or off the bus as crawler crane, parts and the mechanisms such as hydraulic oil container, fuel tank, engine system will be laid usually in inside, and outside is connected with parts such as luffing sheave block, mast, principal arm coxopodite arm, balancer weights.Main valve can be laid at the inner correct position of selecting of turntable according to hydraulic pressure stringing needs and turntable inner space situation, while being hung on turntable inside outside main valve, because the top interface exposes, outside rainwater, dust and other impurities can be polluted the interface on main valve, affect the normal operation of main valve.
The model utility content
The purpose of this utility model is to propose a kind of main valve safety cover, can protect main valve to avoid outside pollution.
For achieving the above object, the utility model provides a kind of main valve safety cover, comprising: be arranged at the protection cover body of main valve top, described protection cover body is fixed on turntable inside.
Further, on the turntable crossbeam that the fixed position of described protection cover body is described turntable inside corresponding to described main valve top.
Further; described protection cover body comprises occlusion part and assembly department; described occlusion part covers the total interface of described main valve top from described main valve top, described assembly department is provided with mounting hole, and described assembly department is connected with the tapped hole of the top of described turntable crossbeam by bolt.
Further, described occlusion part comprises flat board and bending plate, and described bending plate is vertically welded on described flat board, and described bending plate leans the side at described turntable crossbeam.
Further, described assembly department and described flat board are integrally manufactured.
Further, the material that described protection cover body adopts is steel plate.
Based on technique scheme, the utility model arranges the protection cover body above main valve, can effectively to main valve, be protected, and makes main valve avoid the pollutions such as outside rainwater, dust.
The accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
The embodiment's that Fig. 1 is the utility model main valve safety cover scheme of installation.
The detailed view that Fig. 2 is Fig. 1 embodiment.
Another embodiment's that Fig. 3 is the utility model main valve safety cover structural representation.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, be an embodiment's of the utility model main valve safety cover scheme of installation.In the present embodiment; the main valve safety cover comprises the protection cover body 4 that is arranged at main valve 3 tops; protection cover body 4 is fixed on the inside of turntable 1; as seen from Figure 1; main valve 3 is arranged on the side of turntable crossbeam 2 of the inside of turntable 1, on the turntable crossbeam 2 that the fixed position of protecting accordingly cover body 4 is main valve 3 top correspondences.
The detailed view that Fig. 2 is circle part in Fig. 1, as can see from Figure 2, protection cover body 4 be arranged on main valve 3 directly over, and be connected on turntable crossbeam 2 by a plurality of bolts 5.
Fig. 3 shows the concrete structure of main valve safety cover; wherein, protection cover body 4 comprises occlusion part and assembly department 43, and occlusion part covers the total interface of main valve 3 tops from the top of main valve 3; assembly department is provided with mounting hole, and assembly department is connected with the tapped hole of the top of turntable crossbeam 2 by bolt 5.
Occlusion part comprises flat board 41 and bending plate 42, and bending plate 42 is vertically welded on dull and stereotyped 41, and bending plate 42 leans the side at turntable crossbeam 2.Assembly department 43 can be integrally manufactured with flat board 41, also can separately manufacture and be welded.
In order to make the main valve safety cover more durable, corrosion-resistant, protection cover body 4 can adopt steel plate as making material, also is convenient to be welded.
The explanation of embodiment by above-mentioned main valve safety cover, can see that the main valve top arranges the safety cover body and can effectively be protected main valve, makes main valve avoid the pollutions such as outside rainwater, dust.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or the part technical characteristics is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
