Abstract
The utility model discloses a hydraulic support cap belongs to the accessory on the hydraulic support is used in the mechanical coal mining, and the intensity that has solved current hydraulic support cap existence is low, fragile, the relatively poor problem of security and reliability, including curb plate and cap body, and ear plate one and ear plate two of setting on the cap body, cap body middle part position is provided with the ball socket, and the cap body is the overall structure spare that the forging of high strength alloy structure steel formed, and ear plate one, ear plate two, curb plate are in the same place with the welding of cap body respectively, and the peripheral rib of ball socket is the clinohedral, the utility model has the advantages of compact structure, intensity increase, production efficiency obtains improving, and security and life all obtain the extension, can satisfy hydraulic support's service condition better, applicable in various hydraulic support.
Description
Technical field
The utility model belongs to machinery and mines with the accessory on the hydraulic support, particularly a kind of cap of hydraulic support.
Background technology
Hydraulic support cap is positioned at inside and outside two of the back timbers of hydraulic support neutral gear place in the middle of the main muscle, be placed on the back timber top board, and be connected flexible by column respectively with two root post column caps of hydraulic support by bearing pin, briquetting to realize the mine variation of height of hydraulic support self.The back timber of hydraulic support also bears horizontal frictional force and lateral force except the pressure that bears the mining area top board, stressing conditions is comparatively complicated abominable, very easily damages.Therefore, cap is an important stressed member of hydraulic support in the hydraulic support.At present hydraulic support cap adopts casting to process usually, presses under the frequent working environment of alternation at high workload resistance and ore deposit, and this cap root easily ruptures, and draws back easily with part weld seam on every side, and safety factor is lower herein thereby cause.
The utility model content
The purpose of this utility model is: solve that the intensity that existing hydraulic support cap exists is low, fragile, safety and the relatively poor problem of reliability, provide a kind of intensity height, long service life, safety and reliability is higher, the simple hydraulic support cap of manufacturing process.
The technical solution of the utility model is:
A kind of hydraulic support cap comprises side plate and cap body, and is arranged on otic placode one and otic placode two on the cap body, and cap body medium position is provided with ball-and-socket, and described cap body is the solid forging part.
Described otic placode one, otic placode two weld together with the cap body.
Described side plate and cap body weld together.
The peripheral reinforcing section of described ball-and-socket is a clinohedral.
The utility model forges as a whole member with stressed critical piece cap body, improved its stress structure, avoid crossing destressing and concentrated flimsy problem, and can be with other accessory such as otic placode one, otic placode two, the low slightly alloy steels of employing intensity rank such as side plate are made, can guarantee to save cost on the main body intensity based, change the peripheral reinforcing section of ball-and-socket into clinohedral, simplify the structure, compared with prior art, has compact conformation, the advantage that intensity increases, production efficiency is improved, and all obtains in safety and application life prolonging, can satisfy the service condition of hydraulic support better, applicable to various hydraulic supports.
Description of drawings

Fig. 2 is a vertical view of the present utility model;
Fig. 3 is a left view of the present utility model;
Number in the figure, the 1st, side plate, the 2nd, otic placode one, 3rd, otic placode two, 4th, cap body, the 5th, ball-and-socket.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As Fig. 1, Fig. 2, shown in Figure 3, hydraulic support cap comprises by yield point and is higher than the cap body 4 that the structural alloy steel solid forging of 800MPa forms, and welding together otic placode 1, otic placode 23 and side plate 1 respectively with it, otic placode 1, otic placode 23 and side plate 1 are processed into respectively by the alloy-steel plate that yield point is higher than 500MPa.
Adopt the present embodiment of said structure, improved manufacturing efficient, improved intensity and application life, thus the safety factor height, and be easy to promote.
