Abstract
The invention discloses a face guard lockout mechanism, which belongs to the field of mining mechanical equipment. The face guard lockout mechanism comprises a beam body, a face guard hinged to the beam body, and a wedge-shaped mechanism. Gaps in the beam body and the face guard are communicated with each other. When the face guard is unfolded, the wedge-shaped mechanism is fixed in the gaps between the face guard and the beam body in an overlapping mode. The face guard lockout mechanism structurally improves joint strength of the face guard and the beam body and support ability of the face guard. After the face guard is extended out, due to support force provided by the wedge-shaped mechanism, support force of the face guard to a top plate can be effectively increased so as to prevent faces from tilting. Due to the increased support ability, the face guard can be used as a part of the beam body, and accordingly, actual needs for large support force are met on the condition of limited length of the beam body.
Description
Technical field
The present invention relates to a kind of beam support structure that is used for hydraulic support, particularly relate to a kind of wall supporting locking mechanism.
Background technology
Along with economic develop rapidly, energy demand increases, and comprehensive mining hydraulic bracket has obtained using commonly.Coal mining output requires increasing, requires the each coal mining output of coal-winning machine to increase, the also corresponding increase of top board unsupported back span, and this just requires the beam body under the little size of trying one's best, bigger top plate supporting ability can be provided as far as possible
Existing wall supporting is arranged at the end of beam body more, is articulated and connected through jack or axle with the beam body.This wall supporting because and do not have other syndeton between the beam body, the active force that can bear after stretching out is very little, under the stressed bigger situation of top board, may bend, is out of shape and then causes inclined to one side group, serious also may cause a serious accident.
Summary of the invention
To wall supporting proof pressure problem of smaller in the prior art, the invention provides a kind of wall supporting locking mechanism.Said technical scheme is following:
A kind of wall supporting locking mechanism, the wall supporting that comprises the beam body, is hinged with said beam body also comprises wedge mechanism; In said beam body and said wall supporting, the space that is connected is arranged, when said wall supporting launched, said wedge mechanism was fixed in the space between said wall supporting and the said beam body with overlapping.
In the wall supporting locking mechanism provided by the invention, said wedge mechanism is arranged in the said beam body, and an end of said wedge mechanism is connected with thrust unit.
In the wall supporting locking mechanism provided by the invention, said wedge mechanism is arranged in the said beam body, and the rear end of said wedge mechanism is connected with thrust unit.
In the wall supporting locking mechanism provided by the invention, be provided with position-limit mechanism in the said wall supporting, be used to limit the permanent position of said wedge mechanism.
In the wall supporting locking mechanism provided by the invention, the front end face of said wedge mechanism is the inclined-plane; Said position-limit mechanism is an inclined plate baffle; The angle on said wedge mechanism inclined-plane and the angle of said inclined plate baffle are complementary.
Technical scheme provided by the invention have a following beneficial effect:
The present invention has increased wedge mechanism between wall supporting and beam body, improved the bonding strength of wall supporting and beam body and the enabling capabilities of wall supporting.After wall supporting stretched out, the support force that relies on Wedge device to provide can effectively increase wall supporting the support force of top board is prevented inclined to one side group.
Because the support capacity of wall supporting strengthens, can use as a beam body part, and then realize under limited beam body length, satisfying the actual needs of big support force.
Description of drawings
Fig. 1 is the sketch map of wall supporting locking mechanism provided by the invention when wedge mechanism stretches out.
Fig. 2 is the sketch map of wall supporting locking mechanism provided by the invention when wedge mechanism does not stretch out.
The specific embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
Like Fig. 1, shown in Figure 2, wall supporting locking mechanism of the present invention mainly comprises beam body 3, the wall supporting 1 that is connected with the beam body and is arranged on the wedge mechanism 2 in the beam body.Just be connected between common wall supporting 1 and the beam body 3 through jack.Among the present invention, increased fixed part wedge mechanism 2.When wall supporting 1 did not launch, wedge mechanism 2 was fixed on beam body 3 inside.In beam body 3 and wall supporting 1 set inside the space that is connected is arranged.When wall supporting 1 launches; Wedge mechanism 2 can move to wall supporting 1 with beam body 3 parallel directions on the edge in the space; And be fixed on the middle part of wall supporting 1 and beam body 3 with overlapping; Both the back part of wedge mechanism 2 was fixed in the space in the beam body 3, and last partial fixing forms " locked " mechanism in the space of wall supporting 1 inside.So just increased the bonding strength of wall supporting 1 effectively, improved the support capacity of wall supporting 1 with beam body 3.
Promote wedge mechanism 2 motions for ease, can the rear portion of wedge mechanism 2 be connected with thrust unit.Thrust unit in the present embodiment selects for use jack 4 to realize.When wall supporting 1 launched, jack 4 drove wedge mechanism 2 and in the space of wall supporting 1 and beam body 3, moves back and forth.
The present invention can effectively provide wall supporting 1 and the bonding strength of beam body 3 and the support capacity of wall supporting 1 through wedge mechanism 2 is set; Prevent that wall supporting 1 from group partially taking place, and avoids because the accident that wall supporting 1 supporting power deficiency causes is freeed.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
