Description
[technical field]
The utility model relates to one and belongs to constructing tunnel equipment, is specifically related to a kind of tunnel lining trolley structure of flexibility overlap joint.
[background technology]
Tunnel lining trolley is the capital equipment of Tunnel Second Lining Construction, and it for constructing to the concrete-liner of tunnel inner wall, and has the development history of nearly 20 years in China.The production technology of current tunnel lining trolley is comparatively ripe, and structure is a more and more convergent change also.
Existing conventional tunnel lining trolley (for convenience of description, hereinafter referred to as " chassis ") length specification be 9 meters, 10 meters, 12 meters, because chassis length is longer, the outline radian of chassis front/rear end is difficult to ensure uniformity, particularly in work progress, due to chassis front and back end discontinuity, cause front/rear end to be out of shape and also make a world of difference, thus after construction completes and thes cement solidifies, shaping headroom end profile shape is also probabilistic, after a certain mould constructed by chassis, chassis moves forward, and move into place rear chassis rear end and previously shaping two served as a contrast the continuity that profiled outline carries out overlapping to guarantee that tunnel double-lining is shaped, in overlap joint process, because the outer contour shape of rear Side Template was with previously shaping two to serve as a contrast profiled outline shape inconsistent, when causing overlapping, trolley formwork panel has gap with overlap joint cement surface, and the existence in gap will cause construction time cement slurry flow out from gap, so namely, add the trouble in shutoff gap in construction, can be caused again having constructed the fineness of the complete rear surface of rear tunnel double-lining.
[utility model content]
Technical problem to be solved in the utility model is the tunnel lining trolley structure providing a kind of flexibility overlap joint, avoids the generation in gap between trolley formwork (top template and cheek board) and overlap joint cement surface.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of tunnel lining trolley structure of flexibility overlap joint, comprise a door frame, a top template and two is connected limit mould in top template both ends respectively, described top template is installed on door frame by a top stand, and described limit mould is installed on door frame by complex root brace summer; Described top stand comprises the yoke crosstie that complex root parallel interval is arranged, and every described yoke crosstie is all installed on door frame by longeron on two; The middle part of described top template is connected one first oil cylinder, described first oil cylinder supports auxiliary beam by one first and is installed on yoke crosstie, the both ends of described top template are connected one second oil cylinder respectively, second oil cylinder described in two supports auxiliary beam by one second and is installed on the crossbeam of door frame, limit mould described in two is connected respectively and has a plurality of the 3rd symmetrical oil cylinder, each described 3rd oil cylinder supports auxiliary beam respectively by one the 3rd and is installed on the vertical beam of door frame, and described first oil cylinder, the second oil cylinder, the 3rd oil cylinder are all connected with a Hydraulic Station.
Further, limit mould described in two is connected respectively and has two the 3rd oil cylinders, and the 3rd oil cylinder on limit mould described in two is symmetrical one by one along the crossbeam center line of door frame.
The beneficial effect of the tunnel lining trolley structure of the utility model flexibility overlap joint is: by the setting of the first oil cylinder, the second oil cylinder and the 3rd oil cylinder, top template and cheek board shaping two can be served as a contrast profiled outline and paste extremely by force with previously, namely the generation in gap between trolley formwork (top template and cheek board) and overlap joint cement surface is avoided, thus avoid the trouble in shutoff gap in construction, and ensure that the fineness of the complete rear surface of rear tunnel double-lining of having constructed.
[accompanying drawing explanation]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the schematic diagram of the tunnel lining trolley structure of the utility model flexibility overlap joint.
[detailed description of the invention]
Refer to Fig. 1, the tunnel lining trolley structure of the utility model flexibility overlap joint, comprise door frame 1, top template 2 and two and be connected limit mould 3 in top template 1 both ends respectively, described top template 2 is installed on door frame 1 by a top stand 4, and described limit mould 3 is installed on door frame 1 by complex root brace summer 5, described top stand 4 comprises the yoke crosstie 41 that complex root parallel interval is arranged, and every described yoke crosstie 41 is all installed on door frame 1 by longeron 42 on two, the middle part of described top template 2 is connected one first oil cylinder 61, described first oil cylinder 61 supports auxiliary beam 71 by one first and is installed on yoke crosstie 41, the both ends of described top template 2 are connected one second oil cylinder 62 respectively, second oil cylinder 62 described in two supports auxiliary beam 72 by one second and is installed on the crossbeam 11 of door frame 1, limit mould 3 described in two is connected respectively and has a plurality of the 3rd symmetrical oil cylinder 63, each described 3rd oil cylinder 63 supports auxiliary beam 73 respectively by one the 3rd and is installed on the vertical beam 12 of door frame 1, and described first oil cylinder 61, second oil cylinder 62, 3rd oil cylinder 63 is all connected with a Hydraulic Station (not shown), this Hydraulic Station is the first oil cylinder 61, second oil cylinder 62, 3rd oil cylinder 63 fuel feeding.
In the present embodiment, the quantity of the 3rd oil cylinder 63 be connected respectively on both sides mould 3 is two, and in order to the both sides, tunnel after having made more symmetrical consistent, the 3rd oil cylinder 63 on both sides mould 3 is along the crossbeam 11 center line symmetrical design one by one of door frame 1.
During the utility model application, after a certain mould constructed by chassis, chassis moves forward, and move into place rear chassis rear end and previously shaping two served as a contrast the continuity that profiled outline carries out overlapping to guarantee that tunnel double-lining is shaped, in overlap joint process: under the acting in conjunction of the first oil cylinder 61 and the second oil cylinder 62, top template 2 to previously shaping two served as a contrast overlap joint cement surface corresponding on section and pasted extremely, and under the effect of the 3rd oil cylinder 63, both sides mould 3 equally to previously shaping two served as a contrast overlap joint cement surface corresponding on section and pasted extremely, namely achieve whole trolley formwork extremely to design with the two previously shaping seamless subsides of overlap joint cement surface serving as a contrast section.
To sum up, the utility model is by the setting of the first oil cylinder, the second oil cylinder and the 3rd oil cylinder, top template and cheek board shaping two can be served as a contrast profiled outline and paste extremely by force with previously, namely the generation in gap between trolley formwork (top template and cheek board) and overlap joint cement surface is avoided, thus avoid the trouble in shutoff gap in construction, and ensure that the fineness of the complete rear surface of rear tunnel double-lining of having constructed.
