Be screwed into and adjust bolt 5, when adjustment bolt 5 is moved towards the direction near positioning seat body 3, can be connected to by adjusting bolt 5 reaction force of the butt power that produces on the positioning seat body 3, promote the first wedge 1 and move towards the direction away from positioning seat body 3, thereby reduce the height dimension that the first wedge 1 or the second wedge 2 are vertically gone up.
In the present embodiment first domatic 10 and horizontal plane between the angle that exists be acute angle (seeing that from other direction acute angle also can be considered as the obtuse angle).As long as this angle be acute angle then all within protection domain of the present utility model, this acute angle can be 0 °～60 ° particularly, also can be other angles.Be preferably 0 °～15 ° or 3 °～15 ° or 5 °～15 °.Usually this acute angle is the smaller the better.Certainly, this acute angle also can be fabricated to 15 °～60 °, at this moment, more preferably is 15 °～45 °.
Because first domatic 10 and second domatic 20 connect, thus first domatic 10 when being acute angle with the angle of horizontal plane existence, second domatic 20 and horizontal plane between angle also be acute angle.
Such as Fig. 8 and shown in Figure 9, securing member 4 can be screw rod or screw in the present embodiment, be preferably screw rod, be provided with positioning screw hole on the positioning seat body 3, be provided with pilot hole 12 on the first wedge 1, securing member 4 arranges the external screw thread that externally threaded part runs through on pilot hole 12 and the securing member 4 and matches with positioning screw hole.
By the mode of tightening fastener parts 4, can the first wedge 1 be fixed on the positioning seat body 3 by securing member 4.
Pilot hole 12(is preferably slotted hole as shown in Figure 3 in the present embodiment) size of in the vertical direction is greater than externally threaded external diameter on the securing member 4.
Present embodiment intermediate gap adjusting device comprises that at least one number of adjusting the spacing screw 11 that arranges on bolt 5, the first wedges 1 is consistent with the number of adjusting bolt 5.
Adjusting the number of bolt 5 can set according to the size of the first wedge 1, both can set one, also can set two or more.
Present embodiment intermediate gap adjusting device comprises that the number of the positioning screw hole at least two securing members 4, the first wedges 1 is consistent with the number of securing member 4, and the position of spacing screw 11 on the first wedge 1 is between two positioning screw holes.
With adjust bolt 5 in like manner, the number of securing member 4 also can be set according to the size of the first wedge 1, both can set one, also can set two or more.
Also be arranged with packing ring 6 in the present embodiment on screw rod or the screw, the head of screw rod or screw presses on packing ring 6 on the first wedge 1.
The first wedge 1 deviates from first domatic 10 part and the second wedge 2 and deviates from least one of them plane for paralleling with horizontal plane of second domatic 20 part in the present embodiment.
To assemble up difficulty less for the first wedge 1 and the second wedge 2 in this structure, and the attended operation between the second wedge 2 and track beam upper cover plate 81, the vehicle frame supporting leg 82 is more easy.
Also be provided with handle 7 on the first wedge 1 in the present embodiment.Handle 7 can use pipe fitting or rod member bending as being welded in behind C shape or the U-shaped on the first wedge 1 again.Can grab eaily by handle 7 take, install, dismounting the first wedge 1.
The first wedge 1 and the second wedge 2 are quadrangular in the present embodiment, and the first wedge 1 and the second wedge shape cross section separately are all at right angles trapezoidal.This structure the first wedge 1 and the second wedge 2 intensity are higher.Certainly, the first wedge 1 and the second wedge 2 are designed to the technical scheme of triangular prism also within protection domain of the present utility model.
Such as Fig. 1～shown in Figure 9, the dynamic compaction machinery that the utility model embodiment provides comprises the lash adjusting device that track beam upper cover plate 81, vehicle frame supporting leg 82 and the arbitrary technical scheme of the utility model embodiment provide, wherein:
Positioning seat body 3 in track beam upper cover plate 81 or vehicle frame supporting leg 82 and the lash adjusting device is fixedly connected with.Certainly, track beam upper cover plate 81 or vehicle frame supporting leg 82 and positioning seat body 3 are that the technical scheme of integral type structure is also within protection domain of the present invention.
Track beam upper cover plate 81 and vehicle frame supporting leg 82 one of them and the first wedge 1 deviate from first domatic 10 the mutual butt of part.
Wherein another deviates from second domatic 20 the mutual butt of part or fastened to each other the connection with the second wedge 2 for track beam upper cover plate 81 and vehicle frame supporting leg 82.
As one of optimal technical scheme of the present utility model.As shown in Figure 8, vehicle frame supporting leg 82 and the first wedge 1 deviate from first domatic 10 the mutual butt of part, and track beam upper cover plate 81 and the second wedge 2 deviate from for second domatic 20 fastened to each other connection of part (being specifically as follows welding).
Such as Fig. 1～shown in Figure 9, also illustrated track beam lower cover 83 in the local accompanying drawing.
When the lash adjusting device that the utility model embodiment is provided is installed between track beam upper cover plate 81 and the vehicle frame supporting leg 82, in track beam upper cover plate 81 and vehicle frame supporting leg 82 gaps become large process, can move the first wedge 1, make first domatic 10 on second domatic 20 towards sliding near the direction of positioning seat body 3 with the first wedge 1 or the height dimension vertically gone up of the second wedge 2 as shown in Figure 8 that raises gradually as shown in Figure 1 and Figure 4, treat to use when height dimension that the first wedge 1 or the second wedge 2 are vertically gone up reaches the height that needs securing member 4 that the first wedge 1 is fixed on the positioning seat body 3, thereby the gap between track beam upper cover plate 81 and the vehicle frame supporting leg 82 is adjusted to ideal value, and (ideal value should guarantee that the gap is as far as possible few, guaranteeing again again can be too not tight between track beam upper cover plate 81 and the vehicle frame supporting leg 82, usually ideal value is zero), simultaneously, in the process that track beam upper cover plate 81 and vehicle frame supporting leg 82 gaps diminish, can be screwed into and adjust bolt 5, make and adjust bolt 5 towards advancing near the direction of positioning seat body 3, thereby make the first domatic 10 height dimension that court slides and vertically goes up to reduce gradually the first wedge 1 or the second wedge 2 away from the direction of positioning seat body 3 on second domatic 20 by the reaction force of adjusting the butt power between bolt 5 and the positioning seat body 3, thereby the gap between track beam upper cover plate 81 and the vehicle frame supporting leg 82 is adjusted to ideal value.
Therefore, the upper cover plate and the size of vehicle frame supporting leg 82 gaps of the relative position that the utility model can change the first wedge 1 and the second wedge 2 as required to adjust track beam, thus realize adjusting the first wedge 1 and the second wedge 2 and with the upper cover plate of beam, the purpose of size of the power that compresses between the vehicle frame supporting leg 82.Simultaneously, the utility model can be relatively easy to the first wedge is disassembled by regulating the position of adjusting bolt 5, has reduced the dismounting difficulty of the first wedge and the second wedge.
Above-mentioned arbitrary technical scheme disclosed in the utility model unless otherwise stated outside, disclosed number range is preferred number range, any it should be appreciated by those skilled in the art: preferred number range only is the apparent in view or representative numerical value of technique effect in many enforceable numerical value.Because numerical value is more, can't be exhaustive, so just openly part numerical value is illustrating the technical solution of the utility model for the utility model, and the above-mentioned numerical value of enumerating should not consist of the restriction of the utility model being created protection domain.
