Abstract
The utility model discloses a mining monoblock hydraulic prop mainly used for top plate support and protection of mining work surfaces under well in coal mine. The utility model consists of a base, an extension section sleeved in the base, a connecting sleeve sleeved outside the extension section and horizontally provided with an inserted three-use valve, a handle body sleeved outside an oil tank and provided with an inserted active column, and a column cap sleeved outside an upper end of the active column. A lumbar clamping section with a diameter shrinking inward is arranged between two ends of the connecting sleeve. The lumbar clamping section has a cubic structure.
Description
Technical field: the utility model relates to a kind of mine individual hydraulic prop that the coal-face roof timbering is used under the coal mine that is mainly used in.
Background technology: in prior art, failed Chinese utility model patent ＂ middle part liquid injecting type aluminium alloys hydraulic prop ＂ (ZL 88217901.2) discloses a kind of structure of hydraulic prop, it is by the base of socket, lengthening section, adapter sleeve, triple-use valve, oil cylinder, handgrip body, post alive and cap constitute in turn from bottom to up, local recessed on the adapter sleeve intermediate circumference, at the bottom of its shortcoming is adapter sleeve intensity, easily lose.
Summary of the invention: order of the present utility model provides the high mine individual hydraulic prop of a kind of bonding strength.
The purpose of this utility model be achieved in that mine individual hydraulic prop by base, the cap that is enclosed within lengthening section in the base, is enclosed within outer end on the lengthening section and crosses the adapter sleeve that is inserted with triple-use valve, be enclosed within oil cylinder inner on the adapter sleeve, be enclosed within outer end on the oil cylinder and be interspersed with the handgrip body of post alive and be enclosed within the outer upper end of post alive constitutes, it is characterized in that having between the adapter sleeve two ends card waist section of one section inside undergauge, card waist section is a cube structure.Promptly connect to interlock and adopt the square steel pipe structure to replace traditional round steel pipe structure, to improve its bonding strength.This structure both had been applicable to the steel mine individual hydraulic prop, was applicable to the aluminium alloys mine individual hydraulic prop again.For the steel mine individual hydraulic prop, its oil cylinder, the post of living, lengthening section adopt tension, quasi-bainite steel (be approximately higher than 27 SiMn steel about 30 percent, but elongation per unit length being constant) that flexural strength is high.
The utility model has the advantages that: (1) adapter sleeve adopts the square steel pipe structure to replace traditional round steel pipe structure, bonding strength height.(2) oil cylinder, the post of living, lengthening section adopt tension, quasi-bainite steel that flexural strength is high, make the steel mine individual hydraulic prop make 2.8m when above, by reducing wall thickness dimension, and controlled the weight increase, can match in excellence or beauty with the aluminium alloys mine individual hydraulic prop, but price is lower.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Description of drawings: Fig. 1 is the utility model structure diagram.
Fig. 2 is that the part sketch is looked on a left side, Fig. 1 adapter sleeve place.
The specific embodiment: referring to Fig. 1, mine individual hydraulic prop is made of base 1, lengthening section 2, adapter sleeve 4, oil cylinder 5, handgrip body 7, post 6 alive and the cap 8 of socket in turn from bottom to up.Triple-use valve 3 crosses on the card waist section 9 that is inserted in adapter sleeve 4.The card waist section 9 of adapter sleeve 4 is preferred rectangular structure, and promptly the limit with the triple-use valve hole is long limit, and is general to guarantee triple-use valve 3.
Referring to Fig. 2, can more clearly express the square structure of adapter sleeve 4.
Claims (3)
