Abstract
The utility model belongs to the technical field of tunnel construction equipment, specifically a dual-lining trolley structure. The structure solves problems that the normal construction of a tunnel is affected by that a new lining trolley is assembled through anchoring section lining construction, and the investment is high. The structure comprises a lining trolley disposed on a guide rail. The lower side of the lining trolley is provided with a travel system which comprises a travel beam and a travel wheel support. The outer side of the lining trolley is provided with a reversed U-shaped bent wall template. A high block is disposed between the travel beam and the travel wheel support. Two reversed U-shaped pin parts of the lower end of the reversed U-shaped bent wall template are respectively provided with a template. Through the reconstruction of the lining trolley, the structure can completely meet the requirement that the safe construction pace and lining clearance section can be met at lower cost on construction site.
Description
Technical field
The utility model belongs to constructing tunnel equipment technical field, specifically a kind of two lining trolley structures.
Background technology
Constructing tunnel management now, lining cutting is extremely strict with the safe step pitch requirement of excavation face, and the distance of lining cutting hysteresis excavation face can not exceed safe distance requirement.In constructing tunnel, be divided into tunnel and be divided into normal reach and anchor section, in the time of anchor section lining construction, if assemble new lining trolley, because chassis built-up time is relatively long, easily cause lining cutting to the distance of excavation face be greater than safe distance result, affect front, tunnel normal construction, moreover anchor section work operations amount is less, drop into independent chassis, cost is larger.
Summary of the invention
The utility model is assembled new lining trolley and is affected tunnel normal construction in order to solve anchor section lining construction, and the problem that cost has high input provides a kind of two lining trolley structures especially.
The utility model is taked following technical scheme: a kind of two lining trolley structures, comprise the lining trolley being arranged on rail, lining trolley downside is provided with running gear, running gear comprises walking beam and road wheel support, lining trolley outside is provided with the bent wall form of inverted U, between walking beam and road wheel support, be provided with and increase piece, inverted U pin place, two of bent wall form lower ends is respectively equipped with template.
The described height of increasing piece is that anchor section lining section vault arrives difference between the distance of interior tread upper thread to distance and the normal reach lining section vault of interior tread upper thread; Described template height is the corresponding arc length of anchor section lining cutting radius and the difference of the corresponding camber line of normal reach lining cutting radius.
Compared with prior art, the utility model, by the transformation to lining trolley, can meet job site completely and reach the requirement that meets construction safety step pitch and lining cutting cross-section with less cost.
Brief description of the drawings
Fig. 1 is the utility model structure front view;
Fig. 2 is the utility model texture edge figure;
1-lining trolley in figure, 2-walking beam, 3-increases piece, 4-rail, the bent wall form of 5-, 6-template, 7-road wheel support.
Detailed description of the invention
As shown in Figure 1, 2, a kind of two lining trolley structures, comprise the lining trolley 1 being arranged on rail 4, lining trolley 1 downside is provided with running gear, running gear comprises walking beam 2 and road wheel support 7, lining trolley 1 outside is provided with the bent wall form 5 of inverted U, between walking beam 2 and road wheel support 7, is provided with and increases piece 3, and inverted U pin place, two of 5 lower ends of bent wall form is respectively equipped with template 6.
The described height of increasing piece 3 is that anchor section lining section vault arrives difference between the distance of interior tread upper thread to distance and the normal reach lining section vault of interior tread upper thread; Described template 6 height are the corresponding arc length of anchor section lining cutting radius and the difference of the corresponding camber line of normal reach lining cutting radius.
Taking No. two tunnels of new peach blossom paving as example, 7531 meters of No. two tunnel total lengths of new peach blossom paving, are single-track railway tunnel.Full tunnel is R=1600 rice except 247.14 meters of inducers are positioned at radius, and it is that the curve of R=1400 rice is upper outside that 763.51 meters of outlet sections are positioned at radius, and all the other are all positioned on straight line.On circuit straightway, except anchor section lining section, all the other paragraph lining sections do not change, and are unified standard section.Current constructing tunnel management, lining cutting is extremely strict with the safe step pitch requirement of excavation face, and the distance of lining cutting hysteresis excavation face can not exceed safe distance requirement.Full tunnel has six place's anchor sections, and every director's degree is 120 meters, and the intersegmental distance of anchor is 1280 meters.
By the comparative analysis of cross dimensions, can draw two lining sections do not exist together for:
1. the corresponding camber line of anchor section lining cutting R3 radius is long is 518cm, the corresponding camber line of normal reach lining cutting R3 radius is long is 469cm, the corresponding camber line of anchor section lining cutting R3 radius is than the long 49cm of the corresponding camber line of normal reach lining cutting R3 radius, the radian of the corresponding camber line of anchor section lining cutting R3 radius is 0.487rad, the radian of the corresponding camber line of normal reach lining cutting R3 radius is 0.499rad, although the radian of two camber lines is different, but error is in allowed band, can consider to utilize this template of normal reach lining trolley as a joint of the bent wall form of anchor section lining cutting.
2. anchor section lining section vault is 724cm to the height of interior tread upper thread, normal reach lining section vault is 674cm to the height of interior tread upper thread, and anchor section lining section vault arrives the high 50cm of height of interior tread upper thread to the aspect ratio normal reach lining section vault of interior tread upper thread.
Claims (2)
1. a lining trolley structure, comprise the lining trolley (1) being arranged on rail (4), lining trolley (1) downside is provided with running gear, running gear comprises walking beam (2) and road wheel support (7), lining trolley (1) outside is provided with the bent wall form (5) of inverted U, it is characterized in that: between walking beam (2) and road wheel support (7), be provided with and increase piece (3), inverted U pin place, two of bent wall form (5) lower ends is respectively equipped with template (6).
2. two lining trolley structures according to claim 1, is characterized in that: the described height of increasing piece (3) is that anchor section lining section vault arrives difference between the distance of interior tread upper thread to distance and the normal reach lining section vault of interior tread upper thread; Described template (6) height is the corresponding arc length of anchor section lining cutting radius and the difference of the corresponding camber line of normal reach lining cutting radius.
