Abstract

The invention discloses a hydraulic support stud cap, which belongs to a major stressed component on a hydraulic support for mechanical coal mining and resolves the problems of insufficient strength, easy breaking of the existing hydraulic support stud cap. The invention comprises an ear plate 1 and an ear plate 2 positioned on a soleplate; a ball cave is arranged at the middle of the soleplate; the ear plate 1 and ear plate 2 are integral components forged by alloy structure steel; the reinforcement section at the peripheral of the ball cave is provide with inclined surface. With the adoption of the said structure, the hydraulic support stud cap, which has the advantages of compact structure, greater strength, longer service life and higher reliability, can be applied to a plurality of hydraulic support.

Description

Hydraulic support cap
Technical field
The invention belongs to machinery mines with the main stressed member 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.
Summary of the invention
The objective of the invention is: solve that the intensity that existing hydraulic support cap exists is low, fragile, the problem of safety and poor reliability, a kind of intensity height, long service life, the simple hydraulic support cap of manufacturing process are provided.
The present invention realizes that the above-mentioned purpose technical scheme is:
Hydraulic support cap comprises the otic placode one and the otic placode two that are arranged on the base plate, and the medium position of base plate is provided with ball-and-socket, and otic placode one, otic placode two and base plate are the integrated member by a forging molding of structural alloy steel.
The peripheral reinforcing section of described ball-and-socket is a clinohedral.
Described alloy structure yield of steel is between 800MPa～830MPa.
The present invention adopts each parts one-shot forming of hydraulic support cap is forged is overall structure, changed its stress structure, avoid crossing destressing and concentrated flimsy problem, and change the external reinforcing section of ball-and-socket into clinohedral, simplify the structure, yield point is brought up to more than the 800MPa by original 500MPa, has improved intensity greatly.Compared with prior art, the present invention has the advantage that compact conformation, intensity increase, and production efficiency is improved, and all obtains in safety and application life prolonging, and can satisfy the service condition of hydraulic support better, applicable to various hydraulic supports.

The specific embodiment
The present invention is further illustrated below in conjunction with specific embodiments and the drawings.
Embodiment 1: as Fig. 1, Fig. 2, shown in Figure 3, hydraulic support cap is made up of otic placode 1, otic placode 22 and base plate 4, otic placode 1, otic placode 22 and base plate 4 are the solid forging part, and the medium position place of base plate 4 is provided with ball-and-socket 3, and the peripheral reinforcing section of ball-and-socket 3 is a clinohedral.
Otic placode 1, otic placode 22 and base plate 4 are forged by the good structural alloy steel of high strength, weldability and form, and the alloy structure yield of steel is 800MPa, has improved its safety factor, to adapt to the requirement of high strength, high workload resistance, high reliability.
Embodiment 2: basic structure such as embodiment 1, the alloy structure yield of steel that hydraulic support cap adopted is 810MPa.
Embodiment 3: basic structure such as embodiment 1, the alloy structure yield of steel that hydraulic support cap adopted is 830MPa.
