Below in conjunction with Fig. 1 embodiments of the invention are described, bridge substructure impact shock test weight operating means of the present invention comprises base 1, and base 1 lower end is equipped with directional wheel 14 and universal wheel 15.Base 1 is provided with a fixed muffle 12; Sleeve column 2 is installed on the fixed muffle 12; Insert in the aforesaid sleeve column 2 one end of movable loop bar 3, and the other end of movable loop bar 3 is equipped with stressed crossbeam 4, and stressed crossbeam 4 is fixed on the movable loop bar 3 through an installing sleeve 41; On the stressed crossbeam 4 lifting gear is installed, lifting gear comprises the driving reel 7 and fixed pulley 9 that is installed in stressed crossbeam 4 two ends, and the fixed pulley 91 at stressed crossbeam 4 middle parts, wire rope 8 and travelling block 10.The end of wire rope 8 is lifted with a weight 16 through travelling block 10; Movable loop bar 3 is set with connecting pipe 17 with the place, joint portion of sleeve column 2, and connecting pipe 17 is circumscribed with a balance stem 5.Also be provided with the precision rest 13 of a placement weight 16 on the base 1; In the time of need weight being moved to next bridge pier; Weight 16 is risen to the height that is higher than Bridge guardrail through lifting gear; And drop on the precision rest 13 at base 1 center with manpower is auxiliary, then the pin of universal wheel 15 is opened, promote whole device and move forward.
Drive reel 7 and be provided with anti-rotation device, prevent to drive reel 7 during use scrolling takes place.Drive on the reel 7 and can adopt hand gear drive, and travelling block 10 also can save half the power, so the operator can operate lifting gear easily, lifting and decline weight 16; After making weight 16 drop to suitable height through driving reel 7 Wound steel ropes 8, can anti-rotation device be opened, prevent to drive reel 7 reversings, avoid weight 16 to descend suddenly; After blasting operation was accomplished, with the anti-rotation device release, backward rotation drove reel 7, can promote weight 16.
The other end of balance stem 5 is provided with a seat 51, and the lower end of seat 51 is provided with a force rod 52, and the end of force rod 52 is equipped with universal wheel 53 kiss the earths.
Also be provided with a draw ring 11 on the weight 16, also comprise a weight control lever 6, the end of weight control lever 6 is provided with a split ring 61.It is the place that the water surface perhaps should not be stood that weight control lever 6 is used under the bridge, earlier wire rope 8 is released with the control lever that has split ring 61 6, firmly retracts then, thereby drives weight 16 impact bridge piers, experimentizes; Draw ring 11 is used for the place that can stand under the bridge, and draw ring 11 is fastened a stay cord and can be experimentized.
The concrete course of work of present embodiment is narrated as follows:
As shown in Figure 1, during test, earlier with these independently member hang on the walkway of bridge with weight, carry out the operating means assembling according to following steps then and weight is operated:
(1) with universal wheel 15 lockings, sleeve column 2 is inserted in the fixed muffle 12, and the two is fixed with screw;
(2) guardrail height of different bridges can be different, therefore in order to make weight 16 stride across guardrail easily, need confirm the height of stressed crossbeam 4 through the height of adjustment column 3.Movable loop bar 3 is inserted in the sleeve columns 2 and adjusts to suitable height, and fix with bolt;
(3) connecting pipe 17 with balance stem 5 ends is enclosed within on the movable loop bar 3, makes it parallel with guardrail, and fixes with bolt;
The stressed crossbeam 4 that (4) will have a sleeve 41 is contained on the movable loop bar 3, makes it with in balance stem 5 is in the plane parallel with guardrail together, and fixes with bolt;
(5) draw ring with weight 16 1 ends is stuck on the travelling block 10 with buckle, and the operator is sitting on the seat 51 on the balance stem 5, with the weight of balance weight 16, and alleviates operator's labour intensity; With hand rotating drive reel 7 weight 16 is risen to the height above the guardrail top; Bolt between loosening then movable loop bar 3 and the sleeve column 2; Through balance stem 5 control activity loop bars 3, drive stressed crossbeam 4 and revolve and turn 90 degrees the direction vertical with guardrail, backward rotation drives reel 7 then; Weight 16 is dropped to be fit to the height that bridge pier impacts, and the anti-rotation device on the lock drive reel 7;
(6) with weight 16 side knock bridge pier sides.Operation has dual mode: first kind, if be land under the bridge, the operator can fasten on the draw ring 11 of weight 16 ends with rope, comes the side knock bridge pier through rope pulling weight 16; Second kind, if pier in the water, then the operator releases wire rope 8 earlier through the control lever 6 that has split ring 61 on the bridge walkway, firmly retracts then, impacts bridge pier thereby drive weight 16;
(7) through driving reel 7 Wound steel ropes 8 weight 16 is risen to the height that is higher than Bridge guardrail, then with auxiliary its decline of manpower and be placed on the precision rest 13 at base 1 center;
(8) pin of universal wheel 15 is opened, promoted whole device and shift to next pier, then repeating step (1)-(7).
Install lifting, decline and mobile weight with this and can save time more than 50% than traditional manual operation mode, and more laborsaving.
As stated, embodiments of the invention have been carried out explanation at length, but as long as do not break away from inventive point of the present invention and effect in fact, a lot of distortion can have been arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within protection scope of the present invention.
