Description
Technical field
The utility model relates to a kind of linkage tilting prevention device for individual hydraulic props, relate in particular to that comprehensive under coal mine adopted and mining coal work face hydraulic prop between connection and prevent hydraulic prop Self-tipping after topple over the safety device of hurting sb.'s feelings,
Background technology
The anti-down rope of anti-down many employings of underground mine coal-face hydraulic prop at present, although there is the anti-down effect of good monomer, but anti-down rope intensity is lower, worker is more loaded down with trivial details in operating process, and it is more chaotic that scene seems, often because anti-down rope uses lack of standardization, and affect the unimpeded of walkway, and after anti-down rope winding, worker is difficult to reclaim, recycling rate of waterused is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of high-intensity chain monomer tilting prevention device, promotes the anti-down effect of individual prop, improves the recovery reusability of tilting prevention device.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of chain monomer tilting prevention device, comprise shell ring, sleeve pipe and retaining mechanism, shell ring is semicircular snap ring, two shell rings are hinged by folding, the position of two shell ring upper junction plates is all with perforation, in perforation, be installed with bolt, on junction plate, be provided with anti-rotation baffle plate, one of them shell ring is connected with sleeve pipe, casing inner diameter is more than or equal to the external diameter of anti-down bar, retaining mechanism is made up of nut and set lever, and nut-welding is on sleeve pipe, and the lead screw on set lever is contained on nut.
According to described chain monomer tilting prevention device, on junction plate, be provided with two anti-rotation baffle plates, two anti-rotation baffle plates are parallel to each other.
The utility model has the advantages that:
1, improved the anti-down security performance of hydraulic prop, the processing of chain monomer tilting prevention device is simple, and intensity is high, and anti-down effect is better.
2, this device should not damage, and regulates the anti-down height of hydraulic prop practical, makes the anti-down formation concatenate character between hydraulic prop; Can effectively solve the unimpeded of escape way within the scope of coal-face two lane advance safeguards simultaneously, meet the requirement of current national underground mine coal-face quality standardization.

Detailed description of the invention
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Chain monomer tilting prevention device is made up of two parts altogether: anti-down bar 9 and anti-down card are blue.Anti-down bar 9 is that 6 points of hollow steel tubes are made, long 3.0m, and two ends polishing is round and smooth in case hurt sb.'s feelings.The blue iron plate that adopts two wide 50mm, thick 3mm of anti-down card, by being pressed into two cambers, makes shell ring 2.Two shell ring 2 one end utilize folding 1 to be welded connection, and the other end is welded the reserved bolt fastening hole blue shape of card of a diameter 125mm of 4 formation of boring a hole, thereby makes on its cylinder body that can be fixed on individual prop 8.Perforation 4 is provided with bolt, and wherein screw rod hex head end is generally arranged on the junction plate with anti-rotation baffle plate 3.Anti-rotation baffle plate 3 carries out spacing to screw rod, prevent its rotation, prevents that screw rod from rotating in pretension process, facilitates erection bolt.
On the card orchid of making, be welded the sleeve pipe 7 of a diameter 14mm, be used for wearing anti-down bar 9, thereby make individual prop 8 mutually form hard connection, realize chain anti-down effect.Be produced as follows.
Be fixed on continuous three individual props 8 at sustained height blue the anti-down card processing, use bolt to penetrate bolt fastening hole (perforation 4) and fastening good, by in anti-down bar 9 threadings 7, lead screw on fastening handle 5 penetrates the nut 6 that is welded on sleeve pipe 7 and fasteningly fixes anti-down bar 9 again, reaches anti-down effect.Therefore, the external diameter of anti-down bar 9 is not fixed, and the external diameter of anti-down bar 9 is less than or equal to sleeve pipe 7 internal diameters and just can.Set lever 5 with handle just can operate by hand, simple and convenient.
Shell ring 2 adopts is with iron work, and anti-down bar 9 adopts steel pipe manufacturing.Through checking, the chain monomer tilting prevention device using at present has advantages of that volume is little, quality is light, cost is low, and install and use at the scene of being convenient to, and reclaims reusability high, 20,000 yuan of cost-saved inputs every year on average.
Embodiment recited above is described preferred embodiment of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model, all should fall into protection domain of the present utility model.
