Described track gauge adjuster and described adjusting rod are flower basket bolt.
The utility model can realize height to tool track (or claiming elevation) by screw rod micro-adjuster and regulate, and because tool track is fixedly connected with sleeper, is namely therefore the adjustment to sleeper to the adjustment of tool track; The adjustment to two tool track spacing can be realized by track gauge adjuster, the adjustment to two tool track line centers can be realized by adjusting rod.Therefore, the utility model integrates elevation adjustment, gauge regulates, center adjustment three kinds of functions, has structure simple, lightweight, easy and simple to handle, can reduce labour intensity, improve the advantage of efficiency of construction.
The raising that the utility model is the raising in conjunction with high-speed railway construction level and the precision to construction equipment, speed of application requires and the optimal design of carrying out, make that the accurate adjustment of double-block type ballastless track sleeper is convenient, accurately and fast, accurate adjustment efficiency can improve more than 30%.The utility model in use has lightweight, and rigidity is large, and efficiency is high, easy and simple to handle, and labour intensity is low, adapts to the advantages such as various roadbed, bridge, tunnel road.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises the screw rod micro-adjuster 1, track gauge adjuster 2, adjusting rod 3, protecting wall hook 4 and the holder 5 that are set up in parallel.
Screw rod micro-adjuster 1 between adjacent two sleepers, and has two screw rod micro-adjusters 1 between adjacent two sleepers; Two screw rod micro-adjusters 1 are corresponding with the tool track of two on sleeper respectively to be arranged, and screw rod micro-adjuster 1 is corresponding with tool track connects.Screw rod micro-adjuster 1 processes assemble welding by steel plate, for regulating the height of corresponding tool track.
Screw rod micro-adjuster 1 comprises pallet, briquetting, lift block, puller bolt and lift-bolt.Pallet is positioned at the below of corresponding tool track, and it is for supporting corresponding tool track; Briquetting is inverted L shape structure, and the horizontal side arm of briquetting presses the edge, the end of tool track, and the vertical side arm of briquetting is bolted on pallet, screw rod micro-adjuster 1 can be made to be fixedly connected with between tool track by briquetting.Lift block to be arranged on pallet and to be connected with pallet by bearing pin, and puller bolt connects with pallet through the screwed hole on pallet.The quantity of puller bolt is that two, two puller bolts lay respectively at two relative sides of lift block, and the end of puller bolt presses closer the side of lift block.Therefore, by rotating the puller bolt of lift block two sides, puller bolt can be made to loosen (namely not holding out against) lift block, now lift block will rotate along bearing pin, and then the angle of lift block is changed, when the angle of to be hoisted piece rotates to correct position, then rotate puller bolt, realize holding out against of lift block fixing.The utility model can carry out step-less adjustment (namely angular adjustment is continuous print) to the angle of lift block by puller bolt, and the angle of regulation range of lift block is between ﹣ 6 ° ~ ﹢ 6 °.
Lift-bolt from top to bottom through lift block, and is threaded between the two.The bottom of lift-bolt is generally provided with supporter, or is directly placed on ground.Lift block and pallet can be made together to rise or decline by rotating lift-bolt, thus drive tool track together rise or decline, realize the adjustment to tool track elevation.Owing to being threaded between lift-bolt with lift block, therefore, by puller bolt, angular adjustment is carried out to lift block, namely be that angular adjustment is carried out to lift-bolt, this can realize the adjustment to lift-bolt angle fast when freeboard section construction of railways, with ensure lift-bolt all the time with horizontal plane, ensure the center not affecting two tool track lines while adjustment tool track elevation, greatly increase work efficiency.
Track gauge adjuster 2 is arranged between two screw rod micro-adjusters 1.Track gauge adjuster 2 adopts pipe, positive/negative thread nut, positive/negative thread screw rod assemble welding, such as, track gauge adjuster 2 can be made into flower basket bolt; Its two ends respectively with the otic placode pinned connection on two screw rod micro-adjuster 1 pallets.In accurate adjustment process, under the cooperation of screw rod micro-adjuster 1, the object fast distance (abbreviation gauge) between two tool tracks regulated can be realized by track gauge adjuster 2.
The quantity of adjusting rod 3 is two, is separately positioned on the outside of screw rod micro-adjuster 1.Otic placode pinned connection on one end of adjusting rod 3 and screw rod micro-adjuster 1 pallet, the other end is linked up with 4 with holder 5 or protecting wall and is connected.The left end that there is shown left side adjusting rod 3 connects with holder 5, and right-hand member and the protecting wall of right side adjusting rod 3 are linked up with 4 and connected.Holder 5 adopts Plate Welding, is fixed on ground with expansion bolt, and and uses pinned connection between adjusting rod 3.Protecting wall hook 4 adopts channel-section steel assemble welding, hangs on protecting wall, and and uses pinned connection between adjusting rod 3.Adjusting rod 3 adopts pipe, positive/negative thread nut, positive/negative thread screw rod assemble welding, such as, adjusting rod 3 can be made into flower basket bolt.In accurate adjustment process, under the cooperation of screw rod micro-adjuster 1, holder 5 and protecting wall hook 4, can be regulated the center of two tool track lines (being called for short center or center line) by two adjusting rods 3.During concrete adjustment, holder 5 and protecting wall hook 4, push up corresponding adjusting rod 3, and one is drawn corresponding adjusting rod 3, thus can realize the object at two-way quick adjustment center.
