Abstract
The utility model discloses a coal mine hydraulic support bottom lifting device. The coal mine hydraulic support bottom lifting device is characterized in that the coal mine hydraulic support bottom lifting device comprises a top beam, a movable side guard plate, a fixed side guard plate, hinge pins and a pulley mechanism; the pulley mechanism is respectively hinged to the fixed side guard plate and the movable side guard plate through the hinge pins, the fixed side guard plate and the movable side guard plate of the top beam can fall onto the adjacently erected pulley mechanism in the descending process of the top beam, and a base can be lifted through continuing contraction of a stand column. The coal mine hydraulic support bottom lifting device is convenient to install, detach and use, simple in structure, high in strength and low in machining cost.
Description
Technical field
The utility model relates to a kind of technical equipment of support apparatus in coal mine, specifically a kind of coal mine hydraulic supporting bottom lifting device.
Background technology
Coal mine hydraulic supporting bottom lifting device is the important mechanism of fully-mechanized mining working surface hydraulic support of the soft end.The major function of hydraulic support bottom lifting device is support while pricking the end, lifts bracket base, is convenient to support and passes.
At present, hydraulic support adopts floor installation to lift the structure that end jack or adjacent frame are lifted end jack.
At present, in use there is following problem in the hydraulic support bottom lifting device of the type:
(1) on base, install and lift end jack and cause the appearance and size of pusher rod and base elongated, complex structure, design, installation difficulty is higher, weight is heavier;
(2) adjacent frame is installed the complex structure of lifting end jack, and jack, chain, pipeline intersect, and affect pedestrian space.
Summary of the invention
For above deficiency, the purpose of this utility model is to provide coal mine hydraulic supporting bottom lifting device, and it utilizes the hydraulic prop at two ends that the back timber of this hydraulic prop is supported, thereby continue to shrink column, reaches the object of lifting the end.
For achieving the above object, the technical program is as follows:
A kind of coal mine hydraulic supporting bottom lifting device, the hydraulic pressure support unit that comprises parallel arranged, said hydraulic pressure support unit comprises hydraulic prop, the upper end of hydraulic prop is top-loaded with back timber, lower end is connected with base, and the aspectant two ends of described adjacent back timber are respectively provided with backplate and load carrier, when the hydraulic prop of a described support unit shrinks, the side plate of the back timber of this support unit is carried by the load carrier of adjacent cells, now, hydraulic prop continues to shrink, and base lifts.
Further, described backplate comprises that being separately fixed at adjacent back timber upper end coordinates left backplate and right backplate, and the below of each backplate is provided with for carrying the bearing structure of the other side's backplate.
Further, described load carrier is pulley mechanism, and described pulley mechanism is fixed on backplate by bearing pin.
Further, described load carrier is fixed on support, and the other end of support is hingedly fixed on backplate by bearing pin, and when back timber declines, the support of adjacent cells declines and carries its corresponding backplate around pin joint.
Further, support upper end below is provided with bracket, is equipped with the bearing pin for prop on bracket, and when bearing pin is extracted out, support drops to the below that the pulley mechanism of this support now is just in time positioned at adjacent backplate, for support backplate.
Operating principle of the present utility model and the course of work are as follows:
The utility model mainly comprises back timber, movable side protection plate, fixation side backplate, bearing pin, pulley mechanism.Its connected mode is as follows: described pulley mechanism is hinged by bearing pin and fixation side backplate and movable side protection plate respectively.
Fixation side backplate and the movable side protection plate of back timber back timber in falling frame process can drop on the pulley mechanism of adjacent frame, and are shunk and realized the object that base lifts by the continuation of column.
Compared with prior art, this coal mine hydraulic supporting bottom lifting device has not only solved installs on base that to lift pusher rod, base appearance and size that end jack causes large, a difficult problem for Heavy Weight, has solved again adjacent frame the difficult problem that jack, chain, the pipeline lifting end jack and cause intersect has been installed.And bottom lifting device weight is lighter, processing, installation process is simple.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, the accompanying drawing the following describes is only some embodiment that record in the application, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing;
Fig. 1 is the main TV structure schematic diagram of the utility model.
The specific embodiment
The correlation technique content of not addressing below all can adopt or use for reference prior art.
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Embodiment based in the application, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the application's protection.
As shown in Figure 1, a kind of coal mine hydraulic supporting bottom lifting device, comprises back timber 1, and the two ends of back timber are respectively equipped with vertical left side backplate 2, right side backplate 3; Each inner side, backplate below is provided with pulley mechanism 6 by the hinged other end that is provided with support, support of bearing pin 4; The below of bearing pin 4 is provided with bracket, and bracket is provided with bearing pin 5, described support by bearing pin 5 supports, and when bearing pin 5 is extracted out, support drops to the below that the pulley mechanism of this support now is just in time positioned at adjacent backplate, can be used for support backplate.
In order reaching, to facilitate support to lift the object at the end, will on left side backplate 3 and right side backplate 2, pulley mechanism 6 to be all installed.
During use, by pulling and pushing corresponding bearing pin, make back timber 1 in decline process, on the pulley mechanism 6 that the left side backplate 3 of back timber 1 back timber in falling frame process and right side backplate 2 can drop on adjacent frame, and shrink and realize the object that base 8 lifts by the continuation of column 7.
The above is only the application's preferred embodiment, makes those skilled in the art can understand or realize the application.To the multiple modification of these embodiment, will be apparent to one skilled in the art, General Principle as defined herein can be in the situation that do not depart from the application's spirit or scope, realization in other embodiments.Therefore, the application will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
