Below with reference to Fig. 1-Fig. 3, the side seal assembly 100 according to the anchor driving machine (scheming not shown) of the embodiment of the present invention is described.
As shown in Figure 1-Figure 3, according to the side seal assembly 100 of the anchor driving machine of the embodiment of the present invention, comprising: frame 110, door frame 120 and latch components 130.
Specifically, latch components 130 is connected between frame 110 and door frame 120 to be removably mounted in frame 110 by door frame 120.It should be noted that, anchor driving machine may be used for digging straight underground passage, and side seal assembly can be arranged on the both sides of anchor driving machine.In correlation technique, door frame is fixed in frame by bolt or screw, and by the restriction of the working environment of anchor driving machine, dismounting, the installing space of side seal assembly are little, and lane, underground too increases the dismounting difficulty of side seal assembly 100 to interior dim light.Instead of bolt in correlation technique by utilizing latch components 130 or door frame 120 is mounted in frame 110 by screw, thus reduce door frame 120 disassembly process to the requirement of the working space of anchor driving machine, improve the space availability ratio in tunnel.Also avoid using special dismantling device to carry out dismounting to door frame 120 simultaneously, thus simplify the disassembly process of door frame 120, reduce the dismounting difficulty of door frame 120, improve the dismounting efficiency of door frame 120.
According to the side seal assembly 100 of the anchor driving machine of the embodiment of the present invention, by utilizing latch components 130, door frame 120 is removably mounted in frame 110, thus reduce door frame 120 disassembly process to the requirement of the working space of anchor driving machine, simplify the disassembly process of door frame 120, reduce the dismounting difficulty of door frame 120, thus improve the dismounting efficiency of door frame 120, conveniently carry out keeping in repair to door frame 120 and safeguard.
As shown in Figure 1-Figure 3, according to one embodiment of present invention, frame 110 is provided with the guide rail 111 for guiding door frame 120 movement.In the process of installing door frame 120, can utilize guide rail 111 that door frame 120 is guided to corresponding installation site, not only facilitate thus and door frame 120 is mounted in frame 110, the efficiency of assembling of door frame 120 can also be improved.Further, latch components 130 can be located at the upper end 121 of door frame, the own wt of door frame 120 can be utilized thus to realize door frame 120 and tensioning between frame 110.Further, as shown in Fig. 2-Fig. 3, the lower end 122 of door frame is suitable for coordinating with guide rail 111, can improve the compact conformation degree of side seal assembly 100 thus.
Such as, in example as shown in Figure 2, the upper end 121 of door frame is connected to the top of frame 110 by latch components 130, and the lower end 122 of door frame coordinates with the guide rail 111 being located at frame 110 bottom.When door frame 120 is mounted in frame 110, can utilize guide rail 111 that door frame 120 is guided to corresponding installation site, when door frame 120 moves to corresponding installation site, can utilize latch components 130 that the upper end 121 of door frame is coordinated with the top of frame 110, door frame 120 can be mounted in frame 110 thus.
For improving the stability that door frame 120 coordinates with guide rail 111, the upper end 112 of guide rail is formed with the guide groove 113 being suitable for coordinating with the lower end 122 of door frame.As shown in Fig. 2-Fig. 3, guide rail 111 extends (left and right directions as shown in Figure 2) in left-right direction, the upper surface of guide rail 111 is formed with the guide groove 113 of opening (top as shown in Figure 3) upward, the lower end 122 of door frame is engaged in guide groove 113, door frame 120 can move in the lateral direction along guide groove 113 thus, guide groove 113 also can limit door frame 120 motion in the longitudinal direction simultaneously, thus door frame 120 can be moved to correct installation site, thus to be convenient to door frame 120 to be assembled in frame 110, to improve the efficiency of assembling of door frame 120.
Further, the lower end 114 of guide rail is removably connected with frame 110, is convenient to thus repair or replace guide rail 111.Alternatively, as shown in Fig. 2-Fig. 3, the lower end 114 of guide rail is provided with connecting portion 115, and connecting portion 115 is connected with frame 110 by threaded fastener 116.Thus, stability and reliability that guide rail 111 is connected with frame 110 can be improved.
For convenience of being mounted in frame 110 by door frame 120, door frame 120 can comprise multiple subracks 123, and each subrack 123 is connected with frame 110 by many group latch components 130.On the one hand, be convenient to door frame 120 to be mounted in frame 110, on the other hand, when one of them subrack 123 is damaged, can changes this subrack 123, thus save production cost, improve the utilization rate of door frame 120.
In example as shown in Figure 1-Figure 3, latch components 130 can comprise: the first installation portion 131, second installation portion 132, buckling parts 133 and elastic component (scheming not shown).Particularly, the first installation portion 131 can be mounted in frame 110, and the second installation portion 132 can be mounted on door frame 120.One end of buckling parts 133 is pivotably mounted on in the first installation portion 131 and the second installation portion 132, and the other end of buckling parts 133 is suitable for and another clamping in the first installation portion 131 and the second installation portion 132, elastic component often can promote another clamping in the other end of buckling parts 133 and the first installation portion 131 and the second installation portion 132.Thus, not only facilitate and door frame 120 is mounted in frame 110, the reliability that door frame 120 is connected with frame 110 can also be improved.
Here, it should be noted that, when one end of buckling parts 133 is pivotably mounted on the first installation portion 131, the other end of buckling parts 133 and the second installation portion 132 clamping, elastic component is in order to often to promote the other end and second installation portion 132 clamping of buckling parts 133; When one end of buckling parts 133 is pivotably mounted on the second installation portion 132, the other end of buckling parts 133 and the first installation portion 131 clamping, elastic component is in order to often to promote the other end and first installation portion 131 clamping of buckling parts 133.
