Abstract
The utility model relates to the coal mining technology field, especially relates to a light thin seam guide rod-type hydraulic support comprising a top beam, a pedestal, and four hydraulic oil cylinders. The four hydraulic oil cylinders are disposed between the top beam and the pedestal. A vertical elevating guide rod mechanism is disposed between the rear side two hydraulic oil cylinders, and comprises a plurality of rectangular frames, which are sequentially connected together in an inserted manner. The front surface of each of the rectangular frames is provided with an arc-shaped opening, and the position restriction of the adjacent rectangular frames can be realized by positioning pins. According to the design provided by the utility model, the top beam and the pedestal are provided, and the four vertical columns are vertically disposed between the top beam and the pedestal in a supported manner by adopting the hydraulic pressure. The three-stage vertical guide rod mechanism is disposed between the rear vertical columns, and can be used to control the vertical elevating of the support, and in addition, a certain strength can be provided, and therefore the stability of the support can be controlled. The light thin seam guide rod-type hydraulic support has advantages of simplicity, practicability, small occupied effective space, consistent beam end distance, uniform stress state, and ability of using effective supporting force of columns completely.
Description
Technical field
The utility model relates to coal mining suspension device technical field, relates in particular to a kind of light type thin coal seam guide rod type hydraulic support.
Background technology
At present, the hydraulic support that coal mining adopts is all using four-bar linkage structure as stable elevation mechanism, and joins twin columns inclination supporting form and occur, this structural shape complexity, take the usefull space large, beam-ends is large apart from changing, and stress is disliked Lie, volume is large, Heavy Weight, investment is large, and two posts are to tilt to support, effective support force that can not all utilize pillar, is unfavorable for energy-conservation and environmental protection.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides one a kind of lightweight, simple in structure for hydraulic support for low coal seam designs, and is convenient under coal mine carry, and removal of home is face light type thin coal seam guide rod type hydraulic support easily.
The utility model for achieving the above object, by the following technical solutions:
A kind of light type thin coal seam guide rod type hydraulic support, it is characterized in that: comprise back timber, base, hydraulic jack, described hydraulic jack is four, vertical support is between described back timber and base, between two hydraulic jacks of rear side, be provided with vertical lift guide-bar mechanism, described vertical lift guide-bar mechanism comprises several rectangular frames that are plugged in together successively, and the front of described each rectangular frame is provided with arch opening, and described adjacent rectangular frame is spacing by alignment pin.
Described rectangular frame is three, is respectively one-level rectangular frame, secondary rectangular frame and third order moment shape framework, and described one-level rectangular frame is inserted in secondary rectangular frame, and described secondary rectangular frame is inserted in described third order moment shape framework.
The beneficial effects of the utility model are: the utility model is designed with back timber, and base utilizes hydraulic power control four root post vertical support between back timber and base.Between rear column, be provided with three grades of vertical guide stem mechanisms, can control the vertical lift of support, and there is certain intensity, can control the stable of support.Structural shape is simply applicable, takies the usefull space little, and beam-ends is not apart from changing, and stress is even, and volume is little, lightweight, invests littlely, realizes vertical support, can all utilize effective support force of pillar.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of vertical lift guide-bar mechanism in the utility model;
In figure: 1, back timber; 2, base; 3, hydraulic jack; 4, vertical lift guide-bar mechanism; 5, one-level rectangular frame; 6, secondary rectangular frame; 7, third order moment shape framework; 8, arch opening; 9, alignment pin.
Detailed description of the invention
Describe detailed description of the invention of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of light type thin coal seam guide rod type hydraulic support, comprise back timber 1, base 2, hydraulic jack 3, described hydraulic jack is four, vertical support is between described back timber and base, between two hydraulic jacks of rear side, be provided with vertical lift guide-bar mechanism 4, described vertical lift guide-bar mechanism comprises several rectangular frames that are plugged in together successively, rectangular frame is mainly welded by four block plates and four guide rods, the side of described each rectangular frame is provided with arch opening 8, be convenient to like this be installed on hydraulic support, in order to prevent dropping after rectangular frame from extending, described adjacent rectangular frame is spacing by alignment pin 9.Rectangular frame number can select according to actual conditions, if need the aspect ratio promoting selecting the rectangular frame of a greater number compared with higher position, if needed, the height that promotes is lower just selects lower progression.Specifically, rectangular frame described in the utility model is three, be respectively one-level rectangular frame 5, secondary rectangular frame 6 and third order moment shape framework 7, described one-level rectangular frame is inserted in secondary rectangular frame, and described secondary rectangular frame is inserted in described third order moment shape framework.The outer eaves of one-level rectangular frame is provided with slideway, this slideway coordinates with the slide rail of eaves in secondary rectangular frame, the outer eaves of secondary rectangular frame is provided with slideway, this slideway coordinates with the slide rail of eaves in third order moment shape framework, and two alignment pin are separately positioned on the top of secondary rectangular frame and the top of third order moment shape framework.
The utility model is designed with back timber, and base utilizes hydraulic power control four root post vertical support between back timber and base.Between rear column, be provided with three grades of vertical guide stem mechanisms, can control the vertical lift of support, and there is certain intensity, can control the stable of support.Structural shape is simply applicable, takies the usefull space little, and beam-ends is not apart from changing, and stress is even, and volume is little, lightweight, invests littlely, realizes vertical support, can all utilize effective support force of pillar.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
