Abstract
The invention belongs to mine underground ventilating equipment and in particular relates to a multi-buffering and rising vertical shaft explosion-proof door. The multi-buffering and rising vertical shaft explosion-proof door comprises two blades, a gear, a buffering seat, a guide column, buffering boxes, a buffering limiting cylinder, an upper guide seat, a foundation seat, a hinge, a wedge-shaped beam and a lower guide seat, wherein the two buffering boxes are respectively sleeved on shoulder parts at the two ends of the buffering seat; the bottoms of the two buffering boxes are put on a wellhead foundation; the tops and the bottoms of the buffering boxes are not in contact with the buffering seat; and only after the buffering seat rises for a section of distance, the buffering seat comes into collision with the buffering boxes. According to the invention, energy of explosion impact waves are consumed for multiple times by using a multi-buffering device and the impact force on the guide column, and the foundation is divided into twice. The peak impact force of the guide column on the wellhead foundation during the rising the buffering seat is greatly reduced, the civil engineering requirements and the building cost of the wellhead foundation are reduced, and the foundation seat is simply, reliably and economically fixed.
Description
Technical field
The invention belongs to ventilation equipment under coal mine, be specifically related to the vertical shaft explosion door that a kind of door leaf can rise with buffing pad.
Technical background
The existing vertical explosion proof door that automatically resets in ventilation equipment under coal mine, once generation gas explosion, the impact tension of most of flabellum and buffing pad rising generation will be born in the stopping means of vertical shaft explosion door and basis, like this will be higher to the basic earth-instruction demand of vertical shaft explosion door.And there is following problem:
1, the limitation that arranged by the space of coalmine ventilation well head, infrastructure can not infinitely strengthen, and will cause the fixing unreliable of vertical shaft explosion door, excessively strengthens infrastructure itself simultaneously and can cause basic expense too high.
If 2 vertical automatically reset, explosion proof door adopts very long lead, the kinetic energy that ensures buffing pad and flabellum is all converted into potential energy if having time, lead and foundation base are only subject to friction force when buffing pad rises, lead being produced, it is higher that but buffing pad rises, cause equipment manufacturing cost higher, just larger to basic impact force in the time that buffing pad falls after rise, equally also can cause basic destruction, also need to strengthen infrastructure.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, provide a kind of reduce destroy vertical shaft explosion door basis, with fixing simple, the reliable and economic repeatedly buffering rising vertical shaft explosion door in basis.
The present invention adopts with the following method and realizes:
Repeatedly cushion rising vertical shaft explosion door, it is characterized in that: comprise two flabellums 1, gear 2, buffing pad 3, lead 4, baffle-box 5, buffer limit cylinder 6, upper guide holder 7, foundation base 8, hinge 9, tapered beam 10 and lower guide holder 11; Two described flabellums are connected with buffing pad by hinge, and gear and flabellum are fixed, and gear shaft is coaxial with hinge axis, and gear shaft is coaxial with flabellum gyroaxis; Described buffing pad is placed on foundation base, and is connected with lead by lower guide holder, while being moved upward by lead maintenance buffing pad and the relative position of foundation base; Described lead and foundation base are fixed, and foundation base is fixed on well head basis; Described upper guide holder links together two lead upper ends; Described buffer limit cylinder is positioned at lead upper end, and is fixed on guide holder bottom parallel with lead; Described tapered beam is fixed on buffing pad below; Two described baffle-boxs are enclosed within respectively that the shoulder 3-1 at buffing pad two ends is upper, and bottom is placed on well head basis, but baffle-box do not contact with buffing pad up and down, and after buffing pad rises a segment distance, ability bumps with baffle-box.
The substantive distinguishing features that the present invention is outstanding and significant beneficial effect are:
The present invention adopted multi-buffer device by the energy of explosion wave by repeatedly consuming, and will to lead and basis impact force be divided into twice.Greatly reduce the impact force peak value to well head basis producing by lead when buffing pad rises, reduced the civil engineering on well head basis is required and construction cost, and make foundation base fixing simple and reliable and economical.
Brief description of the drawings
Fig. 1 is for repeatedly cushioning rising vertical shaft explosion door schematic diagram
Fig. 2 is the lateral view of Fig. 1.
In figure: the shoulder 3-1 at flabellum 1, gear 2, buffing pad 3, buffing pad two ends, lead 4, baffle-box 5, the spacing cylinder 6 of level 2 buffering, upper guide holder 7, foundation base 8, hinge 9, tapered beam 10, lower guide holder 11.
Detailed description of the invention
As shown in Figure 1, repeatedly cushion rising vertical shaft explosion door, comprise flabellum 1, gear 2, buffing pad 3, lead 4, baffle-box 5, buffer limit cylinder 6, upper guide holder 7, foundation base 8, hinge 9, tapered beam 10 and lower guide holder 11; Two described flabellums are connected with buffing pad by hinge, and gear and flabellum are fixed, and gear shaft is coaxial with hinge axis, and gear shaft is coaxial with flabellum gyroaxis; Described buffing pad is placed on foundation base, and is connected with lead by lower guide holder, while being moved upward by lead maintenance buffing pad and the relative position of foundation base; Described lead and foundation base are fixed, and foundation base is fixed on well head basis, and described upper guide holder links together two lead upper ends; Described buffer limit cylinder is positioned at lead upper end, and is fixed on guide holder bottom parallel with lead; Described tapered beam is fixed on buffing pad below; Two described baffle-boxs are enclosed within respectively the shoulder 3-1 at buffing pad two ends, and bottom is placed on well head basis, but baffle-box do not contact with buffing pad up and down, after buffing pad rises a segment distance, just bump with baffle-box.
Operating principle of the present invention:
The rising vertical shaft explosion door that repeatedly cushions of the present invention, under coal mine, there is explosion time, under the shock wave being exploded, two flabellums 1 are engaged synchronously and are opened by gear 2, and rise together with buffing pad 3, rise to its shoulder upper surface and baffle-box 5 after certain position and collide, baffle-box 5 absorbs most of kinetic energy of buffing pad 3; If buffing pad 3, flabellum 1 and baffle-box 5 continue to rise together, buffing pad 3 bumps against again with buffer limit cylinder 6, absorbs dump energy; Now, the reaction force producing when buffing pad 3 collides with buffer limit cylinder 6 is only born on basis; Baffle-box 5 first collides with the shoulder 3-1 soffit at buffing pad two ends, and buffing pad 3 is underspeeded, and after then colliding with buffer limit cylinder 6, if still have kinetic energy, by buffer limit cylinder 6 and lead 4, impact force is passed on foundation base 8 and well head basis.
Thus, the present invention adopted multi-buffer device by the energy of explosion wave by repeatedly consuming, and will to lead and basis impact force be divided into twice, thereby reduced the impact force to well head basis.
