Abstract
The utility model provides a lining cutting platform truck portal structure, the main part is elasticity frame, its characterized in that: the elasticity frame comprises with middle elasticity rope the rigidity metal pole of both sides, be provided with a plurality of extension springs between the elasticity rope, be provided with on the one end metal pole and link up the piece, link up through extension spring fixed connection between piece and the metal pole, linking up the piece and being metal curve ring -type, two link up the piece can constitute the buckle, be provided with the dead lever in the buckle for fixed buckle. The utility model has the advantage of scientific and reasonable design, will the utility model discloses install on lining cutting platform truck portal, through the setting of elasticity rope in the elasticity frame and extension spring, messenger's equipment can be crooked when the bend uses, the setting that links up simultaneously, can make two lining cutting platform trucks can the independent assortment with separately, adapt to the needs of difference.
Description
Technical field:
This utility model relates to tunnel lining trolley technical field, specifically a kind of lining trolley portal-framed structure.
Background technology:
Tunnel lining trolley is to have to use for special equipment in constructing tunnel process secondary lining, for the concrete-liner of tunnel inner wall is constructed.Concrete-liner chassis is the nonstandard product that in constructing tunnel process, secondary lining is indispensable.The adjoining rock that existing lining trolley is general is 6 meters to 12 meters, it is all the length of single lining trolley one piece lining cutting, but in actual use, such as some individual tunnels are longer, but tunnel curve is more, and during the less tunnel of curve radius of turn, one cycle of 6 meters of long tunnel tunnel lining trolleys can only lining cutting 6 meters, efficiency is too low, although one cycle of lining trolley 12 meters long can lining cutting 12 meters, but possibly cannot be turned and be passed through when curve location, or can turn and pass through, but there is faulting of slab ends at the section of curve place lining cutting and the section of next cycle, do not reach delivery receiving acceptance standard.
Utility model content:
Technical problem to be solved in the utility model is in that to overcome the defect of prior art, it is provided that a kind of rational in infrastructure, it is possible to increase the lining trolley portal-framed structure of efficiency of construction.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of lining trolley portal-framed structure, main body is resilient bezel, it is characterised in that: described resilient bezel is made up of the rigid metal bar of both sides and middle elastic threads, is provided with multiple extension spring, described one end metallic rod is provided with convergence piece between described elastic threads.
It is connected by extension spring is fixing between described convergence piece and metallic rod.
Described convergence piece is metal curve ring-type, and two convergence pieces can make up buckle, is provided with fixing bar, in order to fixing buckle in described buckle.
This utility model design science is reasonable, this utility model is arranged on lining trolley door frame, setting by resilient bezel Elastic rope and extension spring, make equipment can bend when bend uses, the setting of convergence piece simultaneously, two lining trolley independent assortments can be enable and separate, adapting to different needs.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of buckle of the present utility model.
Detailed description of the invention:
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As shown in Figure 1 and Figure 2, a kind of lining trolley portal-framed structure, main body is resilient bezel 1, and described resilient bezel 1 is made up of rigid metal bar 2 and the middle elastic threads 3 of both sides, is provided with multiple extension spring 4 between described elastic threads 3, described one end metallic rod 2 is provided with convergence piece 5, being connected by extension spring 4 is fixing between described convergence piece 5 and metallic rod 2, described convergence piece 5 is metal curve ring-type, and two convergence pieces 5 can make up buckle 6, fixing bar 7 it is provided with, in order to fixing buckle in described buckle.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
