Background technology
In China mine produced, the protective effect of auxiliary well head safety door was most important.At present, the switching of China's metalliferous mine safety gate mostly is operation manually, is unfavorable for safety in production.
Traditional safety door is that electronic rope traction moves up and down the formula safety door, uses manual operation, has following shortcoming in the process of using: the serious needs of steel rope abrasion are often changed; Tilt to block easily in the safety door operational process, cause bulk deformation, influence is used and is attractive in appearance; Manual manual operation switch Men Yi makes a mistake; Can produce bigger impact when door switch puts in place, shorten the service life of safety door; And when the bigger equipment of transportation long material or volume, the safety door of need dismantling is finished transportation, brings very big inconvenience for actual work.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the object of the present invention is to provide a kind of safety door, make it not only rational in infrastructure, simple installation is easy to maintenance and maintenance, and can shortens the haul-cycle time, promote transport capacity, be convenient to transport long, higher material or equipment simultaneously.
Technical scheme: a kind of safety door, comprise two door bodies that cooperate folding, on door pillar, described bearing comprises bearing seat and the bearing seat base that is used to described Men Tijun by bearing hinge connection; Be equipped with the hydraulic efficiency pressure system of control gate body folding between described door body and the door pillar, described hydraulic efficiency pressure system by the PLC module controls comprises interconnective tooth bar oil cylinder and coupler, and described coupler links to each other with the door body.
Described Men Tiwei is square.
Described door body is provided with the bump rubber that is used for the closed impact of buffered gate body.
Described bump rubber comprises by socket bolt bonded assembly cushion rubber and buffering spacer.
Described hydraulic efficiency pressure system is fixed on the door pillar by cylinder support.
Described hydraulic efficiency pressure system also comprises electromagnetic valve, safety overflow valve, energy storage and unloader valve.
Be provided with transition axis between described tooth bar oil cylinder and the coupler.
Described bearing seat is provided with lid, is provided with thrust ball bearing between described bearing seat and the door body.
Described bearing seat bottom is provided with circlip for shaft.
Be equipped with outside framework oil seal between described circlip for shaft and the door body.
Be provided with outside framework oil seal between described bearing seat and the door body.
Beneficial effect: compared with prior art, safety door of the present invention, compactness rational in infrastructure, be easy to maintenance and maintenance, not only can realize the automation control operation, avoid manual operation to cause error, and be convenient to transport than long or bigger material, the equipment of volume, simultaneously can shorten the haul-cycle time, promote transport capacity, suit in producing running, to apply.
Description of drawings
Fig. 1 is the structural representation of safety door;
Fig. 2 is the hydraulic efficiency pressure system of safety door and the structural representation of bearing;
Fig. 3 is the structural representation after the bearing of safety door amplifies.
The specific embodiment
Below in conjunction with the drawings and specific embodiments invention is described further.
As Fig. 1, Fig. 2 and shown in Figure 3, this safety door comprises two square door bodies 1 that cooperate folding, and door body 1 is hinged on the door pillar 2 by 4 bearings 4, door body 1 is provided with two bump rubbers 3, after door body 1 closure, bump rubber 3 can the buffered gate body 1 impulsive force closed the time, shutter body 1 reduces wear; Cushion rubber and buffer plate are combined into bump rubber 3 by socket bolt; Be provided with hydraulic efficiency pressure system between door body 1 and the door pillar 2 by the PLC module controls, hydraulic efficiency pressure system comprises the tooth bar oil cylinder 6 of control gate body 1 folding, tooth bar oil cylinder 6 links to each other with door body 1 by coupler 8, wherein, be provided with transition axis 7 between tooth bar oil cylinder 6 and the coupler 8, hydraulic efficiency pressure system is fixed on the door pillar 2 by cylinder support 15; Hydraulic efficiency pressure system also comprises electromagnetic valve, safety overflow valve, energy storage and unloader valve; The bearing seat 9 that bearing 4 comprises and door body 1 is used and the bearing seat base 10 of fixed bearing block 9, bearing seat 9 is provided with and covers 11, bearing seat 9 bottoms are provided with circlip for shaft 14, be provided with thrust ball bearing 13 between bearing seat 9 and the door body, wherein, be equipped with outside framework oil seal 12 between circlip for shaft 14 and the door body 1 and between bearing seat 9 and the door body 1.
Working process: this safety door is unified controlled hydraulic system by the PLC module, by the rotation of tooth bar oil cylinder 6, give coupler 8 by transition axis 7 transmissions, and then it is rotating closed to drive door body 1, by bump rubber 3 can the buffered gate body 1 bump closed the time, avoid the wearing and tearing of a body 1; Door body 1 only is hinged on the door pillar 2 by 4 bearings 4, need not basis, bottom and upper beam when door body 1 is installed, thereby when transporting long, higher material or equipment, need not remove a body 1, handled easily; Bearing 4 is fixed on the door pillar 2 by bearing seat base 10, and is solid and reliable; By between circlip for shaft 14 and door body 1, and between bearing seat 9 and the door body 1 outside framework oil seal 12 is set, has dustproof effect in the time of convenient lubricating; Wherein, also be provided with electromagnetic valve, safety overflow valve, energy storage and unloader valve in the hydraulic efficiency pressure system, in the process that cage moves up and down, for energy-conservation, unloader valve can carry out off-load, when cage runs to well head, makes unloader valve stop off-load by the cage signal that puts in place.
This safety door, compactness rational in infrastructure, be easy to maintenance and maintenance, not only can realize the automation control operation, avoid manual operation to cause error, and be convenient to transport long or bigger material, the equipment of volume, can shorten the haul-cycle time simultaneously, promote transport capacity, suit in producing running, to apply.
