Description
Technical field
The utility model belongs to training equipment field, colliery, is specifically related to a kind of coal mine roof plate anchor cable quick-detachment frock.
Background technology
As shown in Figure 1, coal mine roof plate forms primarily of top board 1-1 and the anchor cable 1-2 together with top board 1-1 interference fit.
In prior art, coal mine roof plate does not have special disassembling fixture.It is main that the dismounting of anchor cable uses the instrument direct violences such as hawkbill to disassemble more.Not only waste time and energy, and anchor cable all sides discontinuity is yielding, affects the recycling of anchor cable.
Utility model content
In order to solve the problems referred to above that prior art exists, the utility model provides a kind of coal mine roof plate anchor cable quick-detachment frock.
Coal mine roof plate anchor cable quick-detachment frock of the present utility model:
The first scheme, comprising:
Base, the upper surface of described base offers the anchor cable holddown groove holding anchor cable, and the sidewall of described anchor cable holddown groove offers through hole one, and described through hole one is provided with internal thread, is provided with the fastening bolt with its threaded engagement in described through hole one;
Three vertical rods, three described vertical rods are uniformly distributed on the upper surface of the base being fixed on described anchor cable holddown groove week side;
Middle part is provided with the footstock of anchor cable passage, and described footstock is also provided with three and distinguishes corresponding through hole two with described vertical rod, described footstock can slide up and down along described vertical rod.
The coal mine roof plate anchor cable quick-detachment frock of this programme, when concrete dismounting coal mine roof plate: only by the anchor cable of coal mine roof plate through anchor cable passage, need insert anchor cable holddown groove.Screw fastening bolt, anchor cable is fixed.Then, use jack kind equipment, upwards jack-up footstock, also directly can use iron hammer class instrument upwards to knock footstock, get off by anchor cable from quick-detachment coal mine roof plate.Whole unloading process, external force does not directly act on anchor cable, anchor cable all sides uniform force, does not have distortion situation of scrapping and occurs.Obvious, the coal mine roof plate anchor cable quick-detachment frock that the utility model provides also possesses the advantages such as simple for structure, easy and simple to handle, time saving and energy saving.
Further optimization, the sidewall of described anchor cable holddown groove evenly offers three through holes one.
Three through holes one that the utility model is arranged, relatively uniform layout, can carry out more firm clamping to the anchor cable in anchor cable holddown groove, be beneficial to the dismounting of anchor cable.
Further optimization, described fastening bolt comprises one end and is positioned at the sliding part that the bolt part of described chassis outer side and one end are positioned at described anchor cable holddown groove; Described bolt part and described through hole one threaded engagement, described sliding part can in described through hole one slide anteroposterior, one end that described sliding part is positioned at described anchor cable holddown groove is provided with the groove matched with anchor cable.
Anchor cable is mostly cylindrical shape, and in the utility model, the front end being positioned at anchor cable holddown groove at fastening bolt is provided with the groove structure matched with anchor cable.Fastening bolt when carrying out screwing fastening, by the concave surface of groove and anchor cable fastening, modified line contact contacts for face thus, adds and anchor cable contact area, and then adds frictional force, make fastening bolt more firm to the clamping of anchor cable.
Further optimization, described vertical rod is for being carved with externally threaded screw rod, and in described vertical rod, threaded engagement has nut, and the external diameter of described nut is greater than the diameter of described through hole two.Among the prioritization scheme of this section, can upwards screw by nut the bearing force progressively increased footstock, and then soft anchor cable is disassembled from coal mine roof plate.Operate more laborsaving, and better to anchor cable protection.
Further optimization, in the vertical rod between described nut and described footstock, also threaded engagement has thread bush, described thread bush and described nut is dismountable is fixed together.In actual use, nut due to itself internal whorl less, long-time use after, under larger reaction force acts, often there will be running phenomenon.Among the prioritization scheme of this section, the thread bush set up can tackle afore-mentioned very well, increases the stability of equipment.
Further optimization, the vertical rod between described thread bush and described footstock is also provided with the support set that can slide up and down along described vertical rod.
Further optimization, described anchor cable holddown groove is the through hole three running through bottom surface on described base.Among the prioritization scheme of this section, becoming anchor cable holddown groove is through hole three structure, can tackle the situation that the anchor cable body of rod is long.Long anchor cable can pass from through hole three, to facilitate the dismounting of anchor cable.
Further optimization, this coal mine roof plate anchor cable quick-detachment frock also comprises top board holding device, described top board holding device comprises the pipe being positioned at described anchor cable passage, the top of described pipe is fixedly installed plectane, plectane above the cavity of described pipe offers through hole, and described plectane is positioned at above described footstock.The top board holding device that the utility model increases newly can tackle the coal mine roof plate of different model size.
The technical scheme of the second same idea, comprising:
Base, the upper surface of described base offers the anchor cable holddown groove holding anchor cable, and the sidewall of described anchor cable holddown groove offers through hole one, and described through hole one is provided with internal thread, is provided with the fastening bolt with its threaded engagement in described through hole one; The base upper surface of all sides of described anchor cable holddown groove evenly offers three tapped through holes four;
Three studdles, three described studdle difference threaded engagement are in three described tapped through holes four;
Middle part is provided with the footstock of anchor cable passage, and described footstock can be supported by described studdle and hold;
Described anchor cable holddown groove is the through hole three running through bottom surface on described base.
Scheme two of the present utility model, when specifically using, by the anchor cable of coal mine roof plate through anchor cable passage, inserts anchor cable holddown groove.Screw fastening bolt, anchor cable is fixed.Then upwards precession studdle, namely the front end of studdle supports footstock gradually.Along with front end the continuing to increase footstock resist force of studdle, progressively complete anchor cable and depart from from the dismounting coal mine roof plate.
Further optimization, the top, top of described studdle is fixedly installed irony spherical caps.Among this section of scheme optimized, studdle top is irony spherical caps, without sharp corner angle, holds in process and can not scratch footstock.
Further optimization, this coal mine roof plate anchor cable quick-detachment frock also comprises liquid tube head plucking device, described liquid tube head plucking device comprises the accommodation lumen being positioned at described anchor cable passage, the bottom of described accommodation lumen is fixedly installed nut, be threaded below described nut bolt, and the lower end of described bolt is through described anchor cable holddown groove.
Various optimization features in scheme one are applicable to scheme two too, repeat no more herein.
