Abstract
The utility model discloses a hydraulic support with a bottom lifting device and relates to the technical field of hydraulic supports, aiming at the problems of realizing the bottom-lifting effect of the hydraulic support and facilitating increasing the pedestrian space in the front of the hydraulic support. The hydraulic support with the bottom lifting device comprises a hydraulic support base, wherein a bottom lifting jack is rotationally connected to the hydraulic support base; one end of the bottom lifting jack is rotationally connected with the hydraulic support base, and the other end of the bottom lifting jack is rotationally connected with one end of a bottom lifting rod; the bottom lifting rod can be rotationally arranged at a lever support point on the hydraulic support base, and the distance between the lever support point and the connection point of the bottom lifting rod and the bottom lifting jack is less than the radius of gyration of the other end of the bottom lifting rod; and the bottom lifting jack retracts and extends to drive the bottom lifting rod to rotate around the lever support point. The hydraulic support with the bottom lifting device is suitable for the exploitation of a thin seam.
Description
Technical field
The utility model relates to the hydraulic support technical field, relates in particular to a kind of hydraulic support and bottom lifting device thereof.
Background technology
It mainly is softer or meet the hydraulic support foundation front end that occurs after the water softening and prick end phenomenon with solving base plate that hydraulic support is equipped with bottom lifting device.
Existing bottom lifting device mainly is to lift end jack, and it is positioned at the front end of hydraulic support foundation, lifts the upper end of end jack and the bridge plate of crossing of hydraulic support foundation and joins, and the other end is pressed in to be passed on the framework.Before hydraulic support moves frame, at first give and lifted end jack feed flow, hydraulic support foundation is lifted, move frame then, make that to move frame safer, easily, save manpower.
Existing bottom lifting device is lifted end function for realizing, must arrange bridge plate at the front end of hydraulic support foundation, has so just reduced the anterior pedestrian space of hydraulic support.
Summary of the invention
The utility model provides a kind of hydraulic support with bottom lifting device, can realize that hydraulic support lifts the effect at the end, is convenient to increase the anterior pedestrian space of hydraulic support again.
For achieving the above object, the embodiment of the utility model adopts following technical scheme:
A kind of hydraulic support with bottom lifting device comprises: hydraulic support foundation, and rotating being connected with lifted end jack on said hydraulic support foundation;
A said end and the said hydraulic support foundation of lifting end jack is rotatably connected, and the other end is rotatably connected with an end of lifting bottom bar;
The said bottom bar of lifting is arranged on the lever strong point on the said hydraulic support foundation rotationally, and the said lever strong point is lifted the distance of tie point that bottom bar and said lifts end jack less than the said radius of gyration of lifting the other end of bottom bar to said;
Said the flexible of end jack of lifting drives the said bottom bar of lifting and rotates around the said lever strong point.
Wherein, said piston rod and the said hydraulic support foundation of lifting end jack is articulated, and the said piston rod of lifting end jack is articulated with an end of lifting bottom bar.
Wherein, said hydraulic support with bottom lifting device is to be used for the hydraulic support that girdle has bottom lifting device.
Further, be provided with push rod in the bottom of said hydraulic support, the said other end of lifting bottom bar is resisted against on the said push rod.
The utlity model has the hydraulic support of bottom lifting device; Lift the elongation of end jack; Driving the said bottom bar of lifting rotates around the said lever strong point; When the said other end of lifting bottom bar is supported on a fixed part (like push rod) last time, said hydraulic support foundation front end is lifted along with the rotation of lifting bottom bar.When realizing that hydraulic support is lifted the end, need not arrange bridge plate again like this, be convenient to increase the anterior pedestrian space of hydraulic support at the front end of hydraulic support foundation.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 has the sketch map of the hydraulic support of bottom lifting device for the embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing a kind of hydraulic support with bottom lifting device of the utility model embodiment is described in detail.
Should be clear and definite, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to shown in Figure 1, the utlity model has the hydraulic support of bottom lifting device, comprising: hydraulic support foundation 1, rotating being connected with lifted end jack 2 on said hydraulic support foundation; A said end and the said hydraulic support foundation 1 of lifting end jack 2 is rotatably connected, and the other end is rotatably connected with an end of lifting bottom bar 3; The said bottom bar 3 of lifting is arranged on the lever strong point C on the said hydraulic support foundation 1 rotationally, and said lever strong point C lifts the distance of tie point B that bottom bar and said lifts end jack less than the said radius of gyration of lifting the other end of bottom bar to said; It is the distance that distance that the C point is ordered to B is ordered to D less than the C point; Said the flexible of end jack 2 of lifting drives the said bottom bar 3 of lifting and rotates around the said lever strong point.
The utlity model has the hydraulic support of bottom lifting device; Lift the elongation of end jack; Driving the said bottom bar of lifting rotates around the said lever strong point; When the said other end of lifting bottom bar is supported on a fixed part (like push rod) last time, said hydraulic support foundation front end is lifted along with the rotation of lifting bottom bar.When realizing that hydraulic support is lifted the end, need not arrange bridge plate again like this, be convenient to increase the anterior pedestrian space of hydraulic support at the front end of hydraulic support foundation.
Wherein, said piston rod and the said hydraulic support foundation of lifting end jack is articulated, and the said piston rod of lifting end jack is articulated with an end of lifting bottom bar.The utility model embodiment is not limited thereto, and described being rotatably connected also can be adopted hinged mode.
In one embodiment, be provided with push rod 4 in the bottom of said hydraulic support, the said other end of lifting bottom bar is resisted against on the said push rod 4.
Have the hydraulic support of bottom lifting device described in the present embodiment, use when can be used for thin seam mining.
The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
