Abstract
The utility model particularly relates to a movable variable-cross section lining trolley, which solves the problems of time-and-labor-wasting and high cost of the traditional lining trolley. A vertical beam consists of two longitudinal beams which are respectively placed at the left and the right, a support rod is fixed between the two longitudinal beams, and is formed by a plurality of short rods the two ends of which are fixed with flanges, and a travelling wheel is arranged at the lower end of the vertical beam. The utility model has a reasonable and reliable structural design, smooth construction process and no staggered slab, the lining speed is accelerated, the trolley is moved only by the travelling wheel after the assembly, the width of the trolley is adjusted through the support rod, the construction speed is improved, the main materials of the lining trolley are steel supports, steel fences and other revolving materials which are used for temporary support when a foundation pit is excavated, so the cost is greatly saved, and the utility model has the advantages of better strength, rigidity, stability and convenience in operation.
Description
Technical field
The utility model relates to construction and uses lining trolley, is specially a kind of portable section lining trolley that becomes.
Background technology
The tunnel cross-section that large span becomes the section liner structure changes frequently, and varying dimensions is big, and traditional lining trolley can't use.Adopt full framing mainly to have following problem: 1, support takes up room greatly, and before support was removed, construction equipment can't pass through, and restricts other operations and normally launches, and is unfavorable for the integral construction tissue in tunnel; 2, the circulation material input is many, circulation material expense height; 3, it is long that support is set up the cycle, and lining cutting circulation construction speed is slow; 4, set up support and take a large amount of labours, the personal expenditures height; 5, safety inspection is difficult to implement, and potential safety hazard is many; 6, the big difficulty of span is big, and dismounting speed is slow.
Summary of the invention
The utility model provides a kind of portable section lining trolley that becomes in order to solve the problem that traditional lining trolley existence is wasted time and energy and cost is high.
The utility model is to adopt following technical scheme to realize: the portable section lining trolley that becomes, comprise the vertical beam that is positioned at the left and right sides, be fixed with door frame between the vertical beam, be fixed with bow member on the door frame, the vertical beam outside is provided with steel form, is provided with the hydraulic stem hinged with both between steel form and the vertical beam, vertical beam by about two longerons placing form, be fixed with support bar between two longerons, support bar is to be formed by connecting by the quarter butt that some two ends are fixed with flange, and the vertical beam lower end is provided with road wheel.During operation, realize the length of support bar, and then realize that large span becomes the supporting of bore tunnel steel form to the left and right sides, be convenient to portable the moving of section lining trolley that become by setting up road wheel by the quantity of control quarter butt.
The vertical beam lower end is fixed with the bearing that the lower surface is provided with steel ball, road wheel is provided with the upper surface and has the supporting seat that groove and steel ball are positioned at groove, and road wheel is provided with drive motors, and this structure design is more rationally reliable, and further saved manpower, accelerated efficiency of construction.
Bow member is to be spliced by the short bow member of plurality of sections, and splicing has contiguous block between the short bow member, when distance increases between the chassis vertical beam, can increase the arc length of bow member by contiguous block, further provides cost savings.
The utility model reasonable in design is reliable, the smooth no faulting of slab ends of work progress, improved lining cutting speed, and only need after the chassis assembly unit to move and regulate width by support bar by road wheel, improved construction speed, and the main material of lining trolley is turnover materials such as the steel support, steel waling of temporary lining in the Excavation Process, provides cost savings greatly, has preferably intensity, rigidity, stability and has advantages of simple operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-vertical beam, 2-door frame, 3-bow member, 4-steel form, 5-hydraulic stem, 6-longeron, 7-support bar, 8-quarter butt, 9-road wheel, 10-steel ball, 11-bearing, 12-supporting seat, 13-drive motors, the short bow member of 14-, 15-contiguous block.
The specific embodiment
The portable section lining trolley that becomes, comprise the vertical beam 1 that is positioned at the left and right sides, be fixed with door frame 2 between the vertical beam 1, be fixed with bow member 3 on the door frame 2, vertical beam 1 outside is provided with steel form 4, is provided with and both hinged hydraulic stems 5 between steel form 4 and the vertical beam 1, vertical beam 1 by about two longerons 6 placing form, be fixed with support bar 7 between two longerons 6, support bar 7 is to be formed by connecting by the quarter butt 8 that some two ends are fixed with flange, and vertical beam 1 lower end is provided with road wheel 9.Vertical beam 1 lower end is fixed with the bearing 11 that the lower surface is provided with steel ball 10, and road wheel 9 is provided with the upper surface and has the supporting seat 12 that groove and steel ball 10 are positioned at groove, and road wheel 9 is provided with drive motors 13; Bow member 3 is to be spliced by the short bow member 14 of plurality of sections, and splicing has contiguous block 15 between the short bow member 14.In the specific implementation process, adopt following step to install, lay track, require a left side to lay track, require left and right sides track absolute altitude, spacing to meet the requirements, place road wheel 9 then; Vertical beam 1 is installed, is required vertical beam 1 level and diagonal unanimity; Door frame 2 sling to be installed on the vertical beam 1, and the straight back of vertical adjustment is connected fastening with vertical beam 1 with bolt, before lifting by crane door frame 2 is carried out pre-assembly unit on ground, and fastening door frame 2 all bolts are installed post and shoulder pole girder; The adjustable screw mandrel of last vault is installed bow member 3, the arch leveling, and the chassis center line is consistent with the tunnel center line, and carries out the clear height debugging; Debug and begin to install gang form after qualified, carry out lining construction.Bow member 3 is to be bent by the 25a i iron to form, and every Pin bow member 5 usefulness rhombus rice words supports vertically is connected with shroud, constitutes the inconvenient body of several triangles; 108 seamless steel pipes of hydraulic stem 5 usefulness wall thickness 8mm process.
