Abstract

The utility model discloses a plunger piston suspending type monomer hydraulic pressure mainstay coping, the mainstay coping comprises a top cap and a support saddle, the top cap below is provided with a spherical surface, the support saddle upper is provided with a ball and socket, the spherical surface connects with the ball and socket through a tension rod institution. The top cap and the support saddle adopting the spherical surface to connect, the top cap can turn freely. When receive a partiality load, can still make action on the center position of monomer hydraulic pressure mainstay. Thus improve the steady function and supporting function of the mainstay, prolong the service life of the mainstay. The spherical surface of the top cap faces below, and coordinates with the ball and the socket closely under the action of the tension rod institution, thus can prevent small coal and bug dust from permeating to ensure not go so far as to be jammed. The utility model can be used for the plunger piston suspending type monomer hydraulic pressure mainstay under the coal mine well.

Description

Plunger floating single hydraulic prop top cover
Technical field
The utility model relates to the top cover that the coal face hydraulic Support with Suspending Hollow Plug is used under a kind of coal mine.
Background technology
Known plunger floating single hydraulic prop top cover mainly is made up of post pawl, top cap, head etc., can be divided into three kinds of structures such as removable top cover, integral head cover and cap and form.Under coal mine, the top board of coal generally all is irregular, that is to say hydraulic prop when actual support, and this hydraulic prop top cover and top board are off plumbs, and what top cover was subjected to is eccentric load.The hydraulic prop top cover can't make the center of loading in hydraulic prop when being subjected to eccentric load, easily cause post oil cylinder alive bending, skids in the single-column lower end, thereby has influenced its support performance application life greatly.The spherical slide plane of removable top cover makes progress, and broken coal, dust etc. are very easily invaded, and are stuck easily, cause cisco unity malfunction.
Summary of the invention
The purpose of this utility model is that a kind of plunger floating single hydraulic prop top cover will be provided, and this top cover can make eccentric load act on the center of hydraulic prop.
The purpose of this utility model is achieved in that this stud overcap comprises top cap and bearing, is provided with sphere below the cap of top, is provided with ball-and-socket above the bearing, and sphere links to each other by drag link mechanism with ball-and-socket.
Described drag link mechanism comprises pull bar, the pull bar top is spherical, the top of pull bar linked to each other with the following of top cap, the middle part of pull bar is arranged in the bearing centre bore, the middle part of pull bar order from top to down is with pad, spring and minipad, the pad periphery is positioned at below the step of bearing centre bore, and the lower end of pull bar is connected with cottor pin.
Top of the present utility model cap adopts sphere to be connected with bearing, and the top cap is free to rotate.When being subjected to eccentric load, still can make it act on the center of hydraulic prop.Improve the stability and the bearing performance of pillar, prolonged the application life of pillar.The spherical of top cap and cooperates closely with ball-and-socket under the effect of drag link mechanism down, can prevent infiltrations such as broken coal, dust, guarantees its unlikely being stuck.Can be used for the hydraulic Support with Suspending Hollow Plug under the coal mine.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model.
1. top caps among the figure, 2. bearing, 3. big pad, 4. spring, 5. minipad, 6. cottor pin, 7. pad, 8. pull bar, 9. step.
The specific embodiment
In Fig. 1, this stud overcap comprises top cap 1 and bearing 2, is provided with sphere below the top cap 1, is provided with ball-and-socket above the bearing 2, and sphere links to each other by drag link mechanism with ball-and-socket.
Drag link mechanism comprises pull bar 8, and pull bar 8 tops are spherical, and the top of pull bar 8 linked to each other with the following of top cap 1, and the middle part of pull bar 8 is arranged in bearing 2 centre bores.The middle part of pull bar 8 order from top to down is with big pad 3, pad 7, spring 4 and minipad 5.Big pad 3 peripheries are positioned at below the step 9 of bearing 2 centre bores, and the lower end of pull bar 8 is connected with cottor pin 6.
