Abstract
The utility model aims at solving the problem that hydraulic support stand columns are impacted by the external and are eroded by coal dust, and discloses a hydraulic support stand column protective device, which comprises a telescopic protective sleeve, wherein a permeability straight seam is arranged on the telescopic protective sleeve in the axial direction, a buckle belt which locks the permeability straight seam is arranged along the periphery of the telescopic protective sleeve, neckings are arranged on the two ends of the telescopic protective sleeve, raised limit portions are formed on the edges of the neckings, and adjustable locking buckles are arranged on the neckings which are arranged on the two ends of the telescopic protective sleeve. The hydraulic support stand column protective device protects the outer portion of an oil cylinder of hydraulic support stand columns, and integrally seals and packs stand column telescopic segments in the telescopic protective sleeve, thereby effectively preventing powder dust from penetrating, preventing stand column support oil cylinders and sealing rings from being damaged, prolonging service life of stand column sealing pieces, and improving production efficiency of coal mine enterprises. The hydraulic support stand column protective device is convenient and rapid to mount, convenient to demount, excellent in elasticity and high in safety.
Description
Technical field
The utility model relates to hydraulic support, particularly the protective device of hydraulic support column.
Background technology
In coal mine operation, the column of hydraulic support is infiltrated by the impact of the thing such as ickings in the digging operation and the dust in the tunnel easily, causes the damage of column support oil cylinder and sealing ring, badly influences the application life of column seal.
Summary of the invention
The purpose of this utility model is to solve the defective that hydraulic support column is subject to external impact and coal dust erosion, and a kind of hydraulic support column protective device is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of hydraulic support column protective device comprises retractable guard, and described retractable guard axially has penetrating vertical masonry joint, and the cingulum that pins vertical masonry joint is set along the sheath periphery, and the two ends of retractable guard are provided with reducing, and the reducing edge forms the limiting section of projection.
Reducing on the retractable guard is combined closely with column column cap, suspension column respectively; be connected and fixed with the outer casing wall of hydraulic support column; can be in the in-draw of hydraulic support column lifting travel, compression; and effectively improved compressive strength by export-oriented ripple cambered surface; and the impact of flying to the things such as ickings of column in the operation of available buffer down-hole mining; can effectively change simultaneously the direction of alluvium, the protection column is injury-free.
The utility model is in the oil cylinder outer setting protection of hydraulic support column, vertical column expanding section integrally closed is packaged in the retractable guard, effectively prevent the infiltration of dust, prevented the damage of column support oil cylinder and sealing ring, prolong the application life of column seal, improve coal mining enterprise's production efficiency, had simultaneously convenient, the convenient disassembly of installation; Retractility is good, safe.
Description of drawings
Fig. 1 is the structural representation of the utility model hydraulic support column protective device.
Fig. 2 is the structural representation that adjustable lock links closely.
The 1-retractable guard, the 2-cingulum, the 3-adjustable lock links closely, 101-reducing, 102-limiting section, 301-snap close, 302-locking bar, 303-locking belt.
The specific embodiment
Below in conjunction with accompanying drawing the claimed technical scheme of the utility model is done and to be specified.
As shown in Figure 1; a kind of hydraulic support column protective device described in the utility model; comprise retractable guard 1; described retractable guard 1 axially has penetrating vertical masonry joint; the cingulum 2 that pins vertical masonry joint is set along the sheath periphery; the two ends of retractable guard 1 are provided with reducing 101, and reducing 101 edges form the limiting section 102 of projection.
Retractable guard 1 outside is corrugated, with quality of rubber materials sulfuration pressing global formation, has good wear-resistant resistance to pressure, and water, gas and fluid are corroded better tolerance, and is nonflammable, to bump impulsive contact force large, and it is good to seal tight dustproof effect.
And realize the characteristic that fire-retardant point is high and the electrostatic dissipation rate is good by adding auxiliary agent, increased durability and the safety of product.Retractable guard has penetrating vertical masonry joint on axially, and this is so that can be wrapped in retractable guard on the column, again by the cingulum eyelet.This is so that hydraulic support column protective device described in the utility model: (1) is not subjected to the restriction of column diameter size, and the compliance reason is wide; (2) needn't when making column, just retractable guard be installed on the column,
Reducing 101 at retractable guard 1 two ends arranges adjustable lock and links closely 3, as shown in Figure 2, described adjustable lock links closely and comprises snap close 301 and the locking bar 302 that is separately fixed at locking belt 303 two ends, be locked by snap close after locking bar 302 inserts snap close, linking closely with adjustable lock is fixed on the retractable guard reducing on the outer casing wall of hydraulic support column.
Claims (2)
