Description

The scissors jacklift
Technical field
The present invention relates to a kind of scissors jacklift, especially a kind of new device that can carry out mobile elevating function to the bigger object of weight at narrow working space.Belong to heavy burden lifting moving equipment technical field.
Background technology
At present, if need object is moved and lift work, usually adopt electric block or crane operation mode, but electric block or crane can be subjected 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, and the movement of weight and lift work are only allowed to bring greater inconvenience to the worker with the dismounting of manpower one-handed performance.
Though someone once repeatedly improved this artificial unloading's method, but need to adopt as embrace down, lift manual type to carry out, for these weight big (many more than 500kg according to the scene estimation) objects such as picture motor body, guard shields, as limited by site space, the predicament that the meeting appearance is exerted all one's strength nowhere, can't be exerted all one's strength, the influence mounting or dismounting.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of novel scissor jacklift is provided, this device is subjected to the restriction in space little, flexible moving heavy object and carry out lift work, and range of use is wide.
The technical solution adopted for the present invention to solve the technical problems is: the scissors jacklift is by the lifting propulsion source, car rack body (2), horizontal operation plane (5), castor (3), leg (4); rocking handle (7) and crowbar (6) constitute, leg (4) and castor (3) are fixedly connected on car rack body (2) bottom;
One end of lifting propulsion source is installed on car rack body (2) plane by bolt, the other end of lifting propulsion source (1) is bolted to connection in bottom surface, horizontal operation plane (5), and horizontal operation plane (5) can rise or descend within a certain height;
Crowbar (6) is set on drive screw (12) end of lifting propulsion source, and rocking handle (7) is connected by rectangular opening and drive screw (12) breech face,
Described lifting propulsion source is the scissors jack devices.
Described scissors jack device is made of four hold-down arms (11), drive screw (12), fixed hinge (13), bolt and screw rod (14), top base (17), lower base (15) and slide hinge (16), wherein the other end of one group two hold-down arms (11) is connected with top base (15) with bottom base (17) respectively by bolt, between two hold-down arms (11) of this group by bolt and fixed hinge (13); The other end of another two hold-down arms of group (11) also is connected with top base (15) with bottom base (17) respectively by bolt, be connected with slide hinge (16) by bolt between two hold-down arms (11) of this group, drive screw (12) passes fixed hinge (13) and slide hinge (16) respectively
Rotate drive screw (12), slide hinge (16) can prolong drive screw (12) sway, thereby drives that angle degree between two the every group hold-down arms (11) changes and fixing, thereby allows top base (17) be parked on the 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 installed in the overcoat the top.
Described leg (4) is connected place, four angles, car rack body (2) bottom surely, and castor (3) is solid in the middle of car rack body (2) bottom.
Described rocking handle (7) flexibly connects by drive screw (12) breech face that rectangular opening is connected the lifting propulsion source.
Described car rack body (2) is two-layer drawer-type structure, have take in, storage function.
Principle of work: lifting lifting propulsion source is the novel scissor jack device, uses auxiliary devices such as rocking handle 7 and crowbar 6, and the drive screw (12) of turn novel scissor jack can be realized 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, the scissors jack device has the arbitrary height auto-lock function in the specified altitude scope, control process friction impact, simple and convenient, time saving and energy saving.The load in the rated load can be born in horizontal operation plane (5), and does not deform.Car rack body (2) is that two-layer drawer-type structure is formed, have take in, function such as 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 with castor (3), and conveniently moves.
During use, manually shake handle (7) and drive drive screw (12) rotation, the slide hinge (16) that is socketed on the drive screw (12) is prolonging drive screw (12) sway by screw thread, angle between two groups four hold-down arms (11) changes thereupon, allow be installed in horizontal operation plane (5) on the top base (17) can lifting differing heights.Because two finishing bevel gear cuter taper threads that the top is installed can produce the auto-lock function effect in the fixed hinge (13), horizontal operation plane (5) can fixed in the adjustment height arbitrarily.
The invention has the beneficial effects as follows, in whole process, adopt screw thread transmission friction to impact, the effect of screw thread auto-lock function can fixed in the adjustment height arbitrarily, thereby be parked on the different height and positions, the load in the rated load can be born in the horizontal operation plane, bears weight of object and does not deform, and operation is simple, time saving and energy saving, convenient to use.
