Abstract
The utility model discloses a modified type suspended hydraulic support which comprises a front upright column, a back upright column, a top beam arranged at the upper ends of the front and back upright columns, an overturn beam hinged with the front end of the top beam, a joist slidingly arranged below the top beam, and a hydraulic operation bed arranged at the front side of the back upright column. An overturn oil cylinder is arranged between the top beam and the overturn beam, and a hydraulic rubber hose connected between the hydraulic operation bed and the back upright column is arranged along the anteroposterior direction at the middle part of the lower surface of the top beam. Two sets of limit devices are respectively arranged at the left side and the right side of the lower part of the top beam. The modified type suspended hydraulic support is reasonable in design and simple in structure and can be obtained by improving a conventional suspended hydraulic support. The modified type suspended hydraulic support has stronger adaptability in the working faces of small and medium sized mines which have limited coal resources and complicated and changeable geological conditions, and has superior work efficiency and safety control as compared with the conventional suspended hydraulic support. The modified type suspended hydraulic support gives full play to the advantages and features, eliminates the potential safety hazard and provides good guarantee for mining with high yield and high efficiency.
Description
Technical field
The utility model belongs to the Safety of Coal Mine Production technical field, is specifically related to a kind of modified form suspension moving hydraulic support.
Background technology
But the tradition suspension moving hydraulic support is a kind of automatic moving type light hydraulic support between high-grade conventional mining and fully mechanized mining supporter, and is strong to the compliance of work plane, under multiple complex geological condition through taking the corresponding technical safety measures also can operate as normal.The cantilever support kind model that domestic manufacturer produces is various, exists numerous subtle differences, in the use of different geological conditions different operating face environment, many irrational defectives occurred.Distinct issues such as: fluid pressure line is arranged unreasonablely the most, and the front pillar fluid pressure line of support is that the operation valve before the support rear pillar picks out, and arrives front pillar from the set cap both sides; Under the duty, the liquid in the hydralic hose is influenced by pump pressure and makes the sebific duct hardening, when traversing carriage; The gap of joist and back timber both sides can diminish; Thereby the sebific duct that passes in the middle of making is squeezed off, and waste material increases cost of production; Support is passed jack and back timber in moving the frame process linkage snaps easily to be turned down, and the maintain and replace difficulty is big; The flip beam of back timber front end lacks strict travel limits in working order down, causes the mutual collision of this structural member and front pillar, has shortened the application life of integral device, also has plant maintenance inconvenience simultaneously and jeopardizes unfavorable factor such as staff's safety etc.
The utility model content
The utility model is in order to solve weak point of the prior art, provides that a kind of compliance is stronger, operating efficiency and the higher modified form suspension moving hydraulic support of safety guarantee.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the modified form suspension moving hydraulic support; Comprise front column, rear column, be located at the back timber of front column and rear column upper end, with the hinged flip beam of back timber front end, joist that is located at the back timber below and the hydraulic operation platform that is located at the rear column front side slide; Be provided with overturning oil cylinder between back timber and the flip beam; Be connected with hydralic hose between hydraulic operation platform and the forward and backward column, the hydralic hose that is connected between said hydraulic operation platform and the rear column along back timber soffit middle part fore-and-aft direction arrange.
The left and right sides, said back timber bottom is respectively equipped with a cover stopping means, the back lower place of stopping means hinged ear between back timber and flip beam.
Said every cover stopping means includes the riser that is provided with along fore-and-aft direction, and level is provided with a gag lever post between riser and the hinged ear.
Adopt technique scheme; The hydralic hose that is connected between hydraulic operation platform and the rear column along back timber soffit middle part fore-and-aft direction arrange; When traversing carriage, hydralic hose can just the phenomenon that hydralic hose is squeezed off can not occur between adjacent two hydraulic supports.The setting of stopping means has limited the stroke of flip beam, has not only avoided the flip beam touching front column that rotates backward, and staff's safety when having improved plant maintenance.
The utility model is reasonable in design, and is simple in structure, only needs on the basis of existing suspension moving hydraulic support, to improve to get final product; The middle-size and small-size mine working face limited at coal resources, that complicated geological condition is changeable, compliance is stronger; The more traditional suspension moving hydraulic support of operating efficiency and safety guarantee is more superior; Make its advantageous feature that gives full play of self, eliminate hidden danger, adopt the guarantee that provides good for highly efficient and productive ore deposit.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is that flip beam is turned to the sketch map of below in the middle of Fig. 1.
The specific embodiment
Like Fig. 1～shown in Figure 3; The modified form suspension moving hydraulic support of the utility model; Comprise front column 1, rear column 2, be located at front column 1 and rear column 2 upper ends back timber 3, with the hinged flip beam 4 of back timber 3 front ends, the hydraulic operation platform 6 that slides and be located at the joist 5 of back timber 3 belows and be located at rear column 2 front sides; Be provided with overturning oil cylinder 7 between back timber 3 and the flip beam 4; Hydraulic operation platform 6 is connected with hydralic hose 8 with front column 1 and rear column 2 respectively, the hydralic hose 8 that is connected between hydraulic operation platform 6 and the rear column 2 fore-and-aft direction layout in the middle part of back timber 3 soffits.
The left and right sides, back timber 3 bottom is respectively equipped with a cover stopping means, the back lower place of stopping means hinged ear 9 between back timber 3 and flip beam 4.Every cover stopping means includes the riser 10 that is provided with along fore-and-aft direction, and level is provided with a gag lever post 11 between riser 10 and the hinged ear 9.
Since the hydralic hose 8 that is connected between hydraulic operation platform 6 and the rear column 2 along back timber 3 soffits middle part fore-and-aft direction arrange that when traversing carriage, hydralic hose 8 can the phenomenon that hydralic hose 8 quilts are squeezed off just can not occur between adjacent two hydraulic supports.The setting of stopping means when flip beam 4 upset downwards, is played the effect that stops flip beam 4; As shown in Figure 3; Dotted line is represented normal holding state, has not only avoided flip beam 4 rotate backward touching front column 1 and staff's safety when having improved plant maintenance.
