Description
Technical field
The present invention relates to a kind of Scissor jack trolley, especially a kind of new device that can carry out moving lifting function to the larger object of weight at narrow working space.Belong to heavy burden lifting moving equipment technical field.
Background technology
At present, if need move and lift work object, usual employing electric block or crane operation mode, but electric block or crane can be subject to the restriction of operation field space constraint and device layout in real work, practical operation site space environment is narrow, electric block or crane can not play a role at all, to movement and the lift work only permission manpower one-handed performance dismounting of weight, bring greater inconvenience to worker.
Although someone once repeatedly improved this artificial unloading's method, but need to adopt as embraced down, lift manual type and carry out, for these weight such as picture motor body, guard shield etc. comparatively large (many at more than 500kg according to scene estimation) object, as limited by site space, there will be the predicament of exerting all one's strength nowhere, cannot exert all one's strength, impact mounting or dismounting.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of Novel scissor jack dolly, this device is little by the restriction in space, can moving heavy object and carry out lift work flexibly, and range of use is wide.
This technical scheme using its technical matters of novel solution to adopt is: Scissor jack trolley is by lifting drive source, car rack body (2), horizontal operation plane (5), castor (3), leg (4); rocking handle (7) and crowbar (6) are formed, leg (4) and castor (3) are fixedly connected on car rack body (2) bottom;
The one end in lifting drive source is arranged in car rack body (2) plane by bolt, the other end in lifting drive source (1) is bolted to connection in horizontal operation plane (5) bottom surface, and horizontal operation plane (5) can rise within a certain height or decline;
Crowbar (6) is set on drive screw (12) end in lifting drive source, and rocking handle (7) is connected to by rectangular opening and drive screw (12) breech face,
Described lifting drive source is scissor jack arrangement.
Described scissor jack arrangement is made up of four hold-down arms (11), drive screw (12), fixed hinge (13), bolt and screw rod (14), top base (17), bottom base (15) and slide hinge (16), wherein the other end of one group two hold-down arms (11) is connected with bottom base (17) and top base (15) respectively by bolt, by bolt and fixed hinge (13) between two hold-down arms (11) of this group; The other end of another group two hold-down arms (11) is also connected with bottom base (17) and top base (15) respectively by bolt, be connected with slide hinge (16) by bolt between two hold-down arms (11) of this group, drive screw (12) is each passed through fixed hinge (13) and slide hinge (16)
Rotate drive screw (12), slide hinge (16) can along drive screw (12) sway, thus drive the often angle degree organized between two hold-down arms (11) change and fix, thus allows top base (17) be parked on different height and positions.
Described fixed hinge (13) is made up of overcoat and two finishing bevel gear cuters, and wherein the taper thread of interior two finishing bevel gear cuters of fixed hinge (13) is arranged in overcoat top.
Described leg (4) is connected to four angles place, car rack body (2) bottom surely, and castor (3) is solid in the middle of car rack body (2) bottom.
Drive screw (12) breech face that described rocking handle (7) is connected to lifting drive source by rectangular opening is flexibly connected.
Described car rack body (2) is two-layer drawer-type structure, has storage, storage function.
Principle of work: lifting lifting drive source is Novel scissor jack device, and use the auxiliary device such as rocking handle 7 and crowbar 6, the drive screw (12) of turn Novel scissor jack, can realize horizontal operation plane 5 elevating function within the specific limits.Because fixed hinge (13) is made up of overcoat and two finishing bevel gear cuters, scissor jack arrangement has the arbitrary height auto-lock function in specified altitude scope, control process friction impact, simple and convenient, time saving and energy saving.Horizontal operation plane (5) can bear the load in rated load, and does not deform.Car rack body (2) is two-layer drawer-type structure composition, has the functions such as storage, storage.Car rack body (2) supporting construction is made up of four legs (4) and four castors (3), and when mobile, first leg (4) can oneself rise, and bears heavy duty, and conveniently move with castor (3).
During use, artificial swinging handle (7) drives drive screw (12) to rotate, be socketed in slide hinge (16) on drive screw (12) by screw thread along drive screw (12) sway, angle between two groups four hold-down arms (11) changes thereupon, allows the horizontal operation plane (5) be arranged on top base (17) be elevated differing heights.Because in fixed hinge (13), two can produce auto-lock function effect to the finishing bevel gear cuter taper thread that top is installed, horizontal operation plane (5) can at any adjustment height internal fixtion.
The invention has the beneficial effects as follows, in whole process, adopt screw-driven friction to impact, screw thread self-locking function can at any adjustment height internal fixtion, thus be parked on different height and positions, horizontal operation plane can bear the load in rated load, and bear weight of object and do not deform, operation is simple, time saving and energy saving, convenient to use.
