Abstract
A tail end paste filling structure of an integrated hydraulic support supported and filled by paste comprises a top beam, a base, an upper connecting bar, a front connecting bar and a rear connecting bar, the upper connecting bar, the front connecting bar, the rear connecting bar and the base are hinged in pairs to form a four-bar mechanism, the tail end filling structure is arranged at the rear part of the base, the front view of the tail end filling structure is of the shape with an upper end of the round head taper, the side view of the tail end filling structure is of inclined slope shape, one end of the tail end filling structure is contacted with a telescopic baffle plate of the hydraulic support, the other end of the tail end filling structure is positioned at the rear end of the base, the tail end filling structure is of the inclined shape from the end of the telescopic baffle plate to the rear end of the base, two inner main ribs along the length direction thereof are welded at the base middle part of the tail end filling structure, the base is of the full crotch form, and the tail end filling structure is made by the casting method. The tail end paste body filling structure is of the inclined shape toward the rear end and is provided with a circular arc transition surface at the upper lateral face, when the paste is solidified, the support moves forwardly, the support moving is convenient, the filling part forms an arch structure, and the bearing capability of the solidified paste can be reinforced.
Description
Technical field
The utility model relates to comprehensive mechanical coal mining face timbering equipment under the coal mine, and particularly hydraulic support specifically is a kind of tail end paste body filling structure that is used for support integratedization of paste body filling hydraulic support.
Background technology
Along with the increase of mining depth, the raising of the increase of village migration cost and filling technique technological level, the filling mining technology has become flourish gesture.At present, backfilling goaf generally uses hydraulic filling, filling-up pneumatically cream water to fill out and waste filling.Cream water relative cylinder charge is more convenient, only needs during filling to form seal cavity by baffle plate on the support and dividing plate, and the lotion that reinjects gets final product, and has saved the compacting operation, simplifies the structure of filling and support integrated hydraulic support.But, when adopting paste body filling, lotions such as needs coagulate a period of time just can move frame, if lotion solidifies bad meeting, insufficient strength, then can cause and collapse; And the lotion structural instability of just having solidified, moving difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of tail end paste body filling structure that is used for support integratedization of paste body filling hydraulic support, and the described this tail end paste body filling structure that is used for support integratedization of paste body filling hydraulic support will solve the technical problem that the prior art lotion solidifies instability, moving difficulty.
The purpose of this utility model is achieved through the following technical solutions: this filling and support integrated hydraulic support is by comprising back timber, base, last connecting rod, front rod and back link, last connecting rod, front rod, the hinged in twos formation four-bar mechanism of back link and base, it is characterized in that: described tail end filling structure is located at the base rear portion, this tail end filling structural front view is the taper that the upper end has round end, lateral view is ramped shaped, this tail end filling structure one end contacts with the telescopic baffle of hydraulic support, the other end is positioned at the rear end of base, and tail end filling structure is skewed from the telescopic baffle end to base rear end.
Described base middle part is welded with two interior main muscle along its length direction, is provided with distance between the main muscle in described two, and described base is standard-sized sheet crotch form.
Described tail end filling structure is made by casting method.
Described tail end filling structure lower end and interior main muscle welding.
The utility model is compared with prior art, and its effect is actively with tangible.Originally the tail end paste body filling structure that is used for support integratedization of paste body filling hydraulic support is skewed to the back-end, and its upper side has the arc transition face, reduce the active force of support when support moves forward when lotion solidifies like this to the paste body filling structure, it is convenient to move frame, and making pack portion form domes, the lotion that solidifies bears pressure capability to be strengthened.Tail end filling structure adopts the monoblock cast form, can make its transition slicker and more sly, and more reasonable structure is convenient to move frame.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a lateral view of the present utility model.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, in the present embodiment, this filling and support integrated hydraulic support is by comprising back timber, base, last connecting rod, front rod and back link, last connecting rod, front rod, the hinged in twos formation four-bar mechanism of back link and base, base 1 middle part is welded with two interior main muscle 4 along its length direction, be provided with distance between the main muscle 4 in described two, described base 1 is standard-sized sheet crotch form, described tail end filling structure is welded on the interior main muscle 4 at base 1 rear portion, these tail end filling structure 2 front views are the taper that the upper end has round end, lateral view is ramped shaped, actual is the structure of an approximate cone, these tail end filling structure 2 one ends contact with the telescopic baffle 3 of hydraulic support, the other end is positioned at the rear end of base 1, tail end filling structure 2 is skewed from the telescopic baffle end to base rear end, hydraulic support moves forward when making things convenient for lotion to solidify like this, because tail end filling structure 2 is skewed, so relatively capacity disengaging of tail end filling structure and lotion when moving frame, can not cause it to collapse spoils, simultaneously, lotion is arch, strengthens the lotion bearing capacity that solidifies.Described tail end filling structure 2 is made by casting method, can make its transition slicker and more sly, and more reasonable structure is convenient to move frame.
