Abstract

The utility model relates to a link-arm hanging connection type lifter. A propelling part [3] is arranged in an inner cavity of a fixing part [2] and is matched with the fixing part [2] through screw threads; the fixing part [2] is provided with a long opening in the axial direction; a spindle [4] of the propelling part [3] is connected with link arms [5], [6] in the radial direction; the link arms [5], [6] are threaded through the long opening of the fixing part [2] and are connected with a box body [1]; the spindle [4] of the propelling part [3] is driven by a connected motor. The utility model has the advantages of stable running, high safety, high running accuracy, less friction, long service life and little repair and maintenance cost and is suitable for popularization and application on an elevator and a lifting device.

Description

Link arm hanging-connecting elevator

Technical field

The utility model relates to a kind of elevator, particularly a kind of link arm hanging-connecting elevator that is driven envelope or weight lifting by link arm.

Background technology

General elevator; it all is rotation drive steel rope by the control rotatable parts; envelope is promoted; landing; the derrick internal fixation has at least two tracks; article two, keeping parallelism and equidistant between the track; and keep perpendicular to the ground; envelope is installed between two tracks; work good with track; steel rope connects the envelope lifting; this structure and type of belt drive are that all kinds of elevators provide the foundation; people and material are realized that machinery transports; but owing to have slide relative between steel rope and the traction wheel; even free downslide phenomenon appears; envelope is when starting operation or stopping; it is parallel and vertical that elasticity jumping phenomena about having significantly, track are installed extremely difficult realization, and envelope is difficult to consistent with the track cooperation when operation; cause friction force bigger or inhomogeneous; increase energy consumption and influence stability, no matter put or underlying on the driven equipment, all need be provided with machine room and bearing beam; increased supporting construction cost; trouble is changed in the maintenance of steel rope and maintenance, and long-term use causes fatigue fracture easily, has safety misadventure hidden danger; the control system that it is supporting; safety system and mechanical mechanism complexity, the equipment manufacturing cost lattice are higher.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved link arm hanging-connecting elevator is provided, simplified structure, and cost-cutting reduces maintenance, care work amount and expense, improves safety and stationarity.

The purpose of this utility model can realize by following technical measures: this elevator comprises the linear advancement device, envelope, supporting control system, the linear advancement device has connecting element and projectile, connecting element is provided with inner chamber, projectile is located in the connecting element inner chamber, projectile can be done up and down in connecting element, and straight line moves, it moves to promote projectile by mechanical driver unit and realizes, as hydraulic gear, magnetic force mechanism etc., also can cooperate by the spiral that adopts between projectile and the connecting element, doing up and down by the rotation of driven by motor projectile, straight line moves, the connecting element sectional is formed by connecting, connecting element offers long mouthful vertically, the mandrel of projectile radially is connected with link arm, link arm passes long mouthful of connection envelope of connecting element, envelope is by the mandrel of link arm connection projectile, and when projectile moved, doing up and down by link arm drive envelope, straight line moved.

The advantage that the utility model compared with prior art has is: because of it is lifting and the landing of finishing envelope by the linear advancement device, thereby good stability, high safety has guaranteed the running precision height, and friction is few, long service life, reduce maintenance and upkeep cost, connecting element plays the bearing support effect, does not need machine room, bearing beam and special-purpose derrick, significantly reduced auxiliary facility, can be used on elevator or indoor and outdoor and promote in the operation.

Description of drawings

Fig. 1 is a constructional drawing of the present utility model;

Fig. 2 be Fig. 1 A-A to cutaway view.

The specific embodiment

With reference to Fig. 1, Fig. 2, this elevator comprises linear advancement device and envelope [1], connecting element [2] and projectile [3] are arranged in the linear advancement device, there is an inner chamber connecting element [2] lining, projectile [3] is located in connecting element [2] inner chamber, projectile [3] is provided with outside thread, connecting element [2] is provided with negative thread, the screw-internal thread fit of the outside thread of projectile [3] and connecting element [2], projectile [3] transfers to do up and down in connecting element [2] inward turning, and straight line moves, connecting element [2] sectional is formed by connecting, radial position at connecting element [2] has Yi Changkou vertically, mandrel [4] in the projectile [3] is by driven by motor, envelope [1] is located at outside the linear advancement device, envelope [1] passes through two link arms [5] up and down, [6] passing connecting element [2] links up with projectile [3] mandrel [4] for long mouthful, link arm [5] one ends are fixed on envelope [1] top, other end connection is connected in mandrel [4] upper end by bearing, link arm [6] one ends are fixed on envelope [1] side direction, the other end connects mandrel [4] by bearing, when the mandrel [4] of driven by motor projectile [3] rotates, by link arm [5], [6] straight line moved about drive envelope [1] was done.
