Abstract
The utility model discloses a ball joint screw jack for earthquake relief, which comprises a base plate (1), a double-head screw bolt (2), a long rod screw nut (3) and a ball-head screw nut (4), wherein one end of the double-head screw bolt (2) is connected with internal threads of the base plate (1) while the other end is connected with the long rod screw nut (3), and the other end of the long rod screw nut (3) is connected with the ball-head screw nut (4). The utility model has the advantages of combined assembly for lifting and falling, thereby improving efficiency and reliability of earthquake relief.
Description
Technical field
The utility model relates to jack, is specifically related to a kind of sphero-joint earthquake rescue screw thread jack.
Background technology
At present, general hydraulic jack adopts pump valve cylinder integral structure for easy to carry, works as field work, very convenient during as the automobile changing of tire, but when earthquake, house collapse, the people is crushed under the dilapidated walls of lodging, the situation complexity, the space is narrow and small, a lot of problems occur:
1, under narrow space, jack is put to be entered.
2, the handle of jack is put to good use not open.
3, jack has put in, and skids to can not find fulcrum.
4, jack has found fulcrum, but stressed concentrate, and splits because of fearing the monoblock wall pushed up, and dare not use jack.
Summary of the invention
The purpose of this utility model is, a kind of sphero-joint earthquake rescue screw thread jack is provided, and compound type assembling lifting improves earthquake rescue efficiency and reliability.
The technical scheme that its technical matters that solves the utility model adopts is: this jack is made up of chassis, thru-bolt, stock nut and bulb nut, one end of thru-bolt connects the negative thread on chassis, the other end of thru-bolt connects the stock nut, and the other end of stock nut connects the bulb nut.
In the sphero-joint earthquake rescue screw thread jack of the present utility model, on the bulb nut, top board is installed by the ball hole.
In the sphero-joint earthquake rescue screw thread jack of the present utility model, top board is assembled into by straight pin and pin-and-hole by some square pieces.
In the sphero-joint earthquake rescue screw thread jack of the present utility model, the top pawl is installed on top board.
In the sphero-joint earthquake rescue screw thread jack of the present utility model, thru-bolt and stock nut can any as required assembled lengths.
The utlity model has following advantage: 1, the stock nut can be assembled a plurality ofly, simple in structure according to requirement for height, and volume is less;
2, this jack adopts sphero-joint can adapt to dilapidated walls and ground-surface arbitrarily angled in the narrow space, and fulcrum is flexible;
3, top board adopts the square piece to be assembled by straight pin, but I is big in narrow space, prevent stressed concentrate monoblock wall top split jeopardize personal safety;
4, the top pawl is installed on the top board, can be prevented that top board from skidding;
5, two adjustable angle spanner manually get final product work, solve the difficult problem that handle is put to good use not open.
Description of drawings
Fig. 1 is this single ball head structure scheme drawing.
Fig. 2 is two bulb type jack structure scheme drawings
Fig. 3 is the top board assembly drawing
Fig. 4 is top board and top pawl assembly drawing
Fig. 5 is top pawl figure
Among the figure: 1 chassis, 2 thru-bolts, 3 stock nuts, 4 bulb nuts, 5 top boards, 6 top pawls, 7 straight pins, 8 pin-and-holes.
The specific embodiment
Shown in Fig. 1-5, this jack is made up of chassis 1, thru-bolt 2, stock nut 3 and bulb nut 4, one end of thru-bolt 2 connects the negative thread on chassis 1, and the other end of thru-bolt 2 connects stock nut 3, and the other end of stock nut 3 connects bulb nut 4.
In the sphero-joint earthquake rescue screw thread jack of the present utility model, on bulb nut 4, top board 5 is installed by the ball hole.
In the sphero-joint earthquake rescue screw thread jack of the present utility model, top board 5 is assembled into by straight pin 7 and pin-and-hole 8 by some square pieces.
In the sphero-joint earthquake rescue screw thread jack of the present utility model, top pawl 6 is installed on top board 5.
In the sphero-joint earthquake rescue screw thread jack of the present utility model, thru-bolt 2 and stock nut 3 can any as required assembled lengths.
During work, observe the size in rescue space earlier, the placement space of measuring and calculating jack.If adopt two bulb types, at first lower roof plate is installed according to the space size groups that allows and put in, again jack is put in, bulb withstands in the ball hole of lower roof plate; Then, determine the position of upper plate, make the top pawl be absorbed in the wall shrinkage pool, put into upper plate, by the fixing thru-bolt of adjustable angle spanner, another adjustable angle spanner rotates rising stock nut, make in the bulb nut bulb jacking upper plate ball hole, the top pawl is absorbed in fixedly top board of wall shrinkage pool, and rotating spanner control jack stroke is also promptly controlled the space that ejects, and will be saved out by the people that wall is pushed down.
