Abstract
The utility model discloses an end support and relates to the technical field of hydraulic supports. The end support aims at enabling a side-dump jack to provide large and effective supporting force and comprises a base, wherein an extensible vertical column is arranged on the base, a top beam is arranged at the top end of the vertical column, a side-dump plate is hinged on the lateral portion of the top beam, and a side-dump jack for controlling side-dump angles of the side-dump plate is arranged between the base and the side-dump plate. The end support is suitable for supporting and protecting a mining face end of a coal mining working face.
Description
Technical field
The utility model relates to a kind of face end support, relates in particular to the rollover plate of face end support.
Background technology
Existing face end support comprises base, and said base is provided with telescopic column, is provided with back timber on the top of said column, is hinged with the rollover plate at the sidepiece of said back timber, between said back timber and said rollover plate, is provided with the rollover jack.
In the existing face end support, the rollover jack is arranged between back timber and the rollover plate, and it is bigger with respect to the support angle of column to make the rollover jack do the time spent like this, and the effective support force that provides is less.
The utility model content
The utility model technical problem to be solved is to provide a kind of face end support, and effective support force that its rollover jack can provide is bigger.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of face end support; Comprise base, said base is provided with telescopic column, is provided with back timber on the top of said column; Sidepiece at said back timber is hinged with the rollover plate, between said base and said rollover plate, is provided with the rollover jack of control rollover plate rollover angle.
Wherein, said rollover jack and said base all adopt bulb to ball-and-socket hinged with the hinged place of rollover plate.
Further, be provided with unsteady reversible lock between the epicoele of said rollover jack and the cavity of resorption, the reversible lock that when said column moves, floats is communicated with the upper and lower chamber of rollover jack.
The utility model face end support, because the rollover jack is arranged between base and the rollover plate, the rollover jack is little with respect to the support angle of column, effective support force that can provide is bigger.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model face end support;
Fig. 2 is the hinged sketch map of rollover jack and base in the face end support shown in Figure 1;
Fig. 3 be in the face end support shown in Figure 1 the rollover jack with the rollover plate hinged sketch map.
The specific embodiment
The utility model aims to provide a kind of face end support, and effective support force that its rollover jack can provide is bigger.Below in conjunction with accompanying drawing the utility model embodiment is specified.Should be clear and definite, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to shown in Figure 1; The utility model embodiment face end support; Comprise base 1, said base 1 is provided with telescopic column 2, is provided with back timber 3 on the top of said column 2; Sidepiece at said back timber 3 is hinged with rollover plate 4, between said base 1 and said rollover plate 4, is provided with the rollover jack 5 of control rollover plate rollover angle.
In the utility model face end support, because the rollover jack is arranged between base and the rollover plate, the rollover jack is little with respect to the support angle of column, and effective support force that can provide is bigger.
Referring to Fig. 2 and shown in Figure 3, in one embodiment, said rollover jack and said base all adopt bulb to ball-and-socket hinged with the hinged place of rollover plate.The rollover jack can be realized realizing again changing the swing that relative displacement produces between back timber and the base because of the support mining height along with support-side turnover panel angle changes and swinging of producing like this.
In another embodiment, said rollover jack epicoele and cavity of resorption between be provided with the reversible lock (not shown) of floating, when said column action, the hydraulic control system control reversible lock that floats is communicated with the upper and lower chamber of rollover jack.The jack of avoiding like this turning on one's side produces damage because of the card of spraining.
The rollover jack support angle of the utility model face end support is little, and the effective support force that not can provide by spatial constraints is bigger.
The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion by said protection domain with claim.
Claims (3)
1. face end support; Comprise base; Said base is provided with telescopic column, is provided with back timber on the top of said column, is hinged with the rollover plate at the sidepiece of said back timber; It is characterized in that, between said base and said rollover plate, be provided with the rollover jack of control rollover plate rollover angle.
2. face end support according to claim 1 is characterized in that, said rollover jack and said base all adopt bulb to ball-and-socket hinged with the hinged place of rollover plate.
3. face end support according to claim 1 and 2 is characterized in that, is provided with unsteady reversible lock between the epicoele of said rollover jack and the cavity of resorption, and the reversible lock that when said column moves, floats is communicated with the upper and lower chamber of rollover jack.
