Description
Technical field
The utility model relates to the constituent elements of Coal Transportation machine, is specially a kind of mine car latch anti-drop device.
Background technology
Mine car latch is one of composition of jink, relates to the vitals of safety problem, and safety regulations in coal mine regulation latch must have anti-drop device.
In the past, the anti-drop device of onsite application is special hatch lock shotpin, this anti-drop device (hatch lock shotpin) is although light, but it is not too convenient when using at the scene, be mainly manifested in: workman is after plugging mine car latch, often will lie prone or kneel on the ground, the aperture in alignment pins carries out interspersed lock pin, wastes time and energy; Hatch lock shotpin compact, scene is often lost; In transportation, due to the negligence of workman when interspersed, spring cotter easily comes off, and causes certain potential safety hazard.
Summary of the invention
The utility model adopts hatch lock shotpin anticreep to there is potential safety hazard and waste time and energy to affect the problem of work efficiency, provide a kind of mine car latch anti-drop device to solve existing anti-drop device.
The utility model adopts following technical scheme to realize: mine car latch anti-drop device, comprise two pieces of being fixed on around latch on connecting panel vertically to arrange and the stay bearing plate be parallel to each other, the rotating shaft vertical with both is provided with between two stay bearing plates, rotating shaft is fixed with latch, the rear end of latch is fixed with handle, the front end of latch covers above latch upper surface, and latch front lower ends and connecting panel leave space, and lower end, latch rear portion and connecting panel are close to.
When mine car runs, if latch upward direction is moved, latch will drive the anterior upward vertical movement of latch, latch rear portion is by vertical downward movement, because mine car connecting panel and lower end, latch rear portion are close to, under the antagonistic force of mine car connecting panel drives, the front portion of latch can not upward movement, thus ensure that latch can not come off from latch bore, serve anticreep effect, overcome existing anti-drop device and adopt hatch lock shotpin anticreep to there is potential safety hazard and waste time and energy to affect the problem of work efficiency.
The utility model reasonable in design is reliable, ensure that the stability of latch latch functions, difficult drop-off, and conveniently achieves the handling of latch, significantly improve operating efficiency, has structure simple, durable in use and change advantage easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-connecting panel, 2-stay bearing plate, 3-rotating shaft, 4-latch, 5-handle.
Detailed description of the invention
Mine car latch anti-drop device, comprise two pieces of being fixed on around latch on connecting panel 1 vertically to arrange and the stay bearing plate 2 be parallel to each other, the rotating shaft 3 vertical with both is provided with between two stay bearing plates 2, rotating shaft 3 is fixed with latch 4, the rear end of latch 4 is fixed with handle 5, the front end of latch 4 covers above latch upper surface, and latch 4 front lower ends and connecting panel 1 leave space, and lower end, latch 4 rear portion and connecting panel 1 are close to.
In specific implementation process, if latch need be extracted, hold handle 5 and lifted at latch 4 rear portion, latch 4 front portion will rotate downwards around the shaft, and latch 4 front end departs from above latch, and latch can take out.
