Description
Technical field
The present invention relates to elevator, be specifically related to a kind of trackless lift.
Background technology
At present, elevator comprises actuating unit and load-carrying operating unit; Actuating unit is made up of towing machine, traction sheave, track adjusting wheel and hoist ropes, and traction sheave is installed on the towing machine, and hoist ropes is wrapped on traction sheave and the track adjusting wheel; The load-carrying operating unit is by car, to reassembling into, and through the rail brackets mounting guide rail, car and counterweight operate on the guide rail in the hoistway, and the hoist ropes two ends connect car and counterweight respectively; Drive traction sheave after towing machine (or passing through retarder) speed change and rotate, lean on hoist ropes and the fricative tractive force of traction race, realize the dipping and heaving of car and counterweight, reach the transportation purpose.
On the normal car safety tongs is installed, when elevator overspeed arrives governor tripping speed, or under the situation of hoist ropes fracture, safety tongs is the clamping guide rail under the effect of velocity limiter, makes the car stop that nominal payload is housed and keeps quiescence; Guide rail mainly plays two effects, the one, directional tagging, the 2nd, safety effect.
Present guide tracked elevator has following problem: one, mounting guide rail is wasted time and energy, and installation rate is slow, squareness, parallelism debug difficulties; Two, owing to parallelism, straightness accuracy between guide rail deform with building settlement, ride comfort is poor; Three, the elevator cost is high, and productive costs is big.
Summary of the invention
Technical matters to be solved by this invention is the deficiency to prior art, and a kind of reduction elevator cost is provided, and makes the trackless lift that elevator is quick for installation, debugging is convenient, the operation noise reduces, ride comfort is good.
Technical matters to be solved by this invention is to realize through following technical scheme.The present invention is a kind of trackless lift; Comprise actuating unit and load-carrying operating unit; Actuating unit comprises towing machine, traction sheave, track adjusting wheel and hoist ropes, and traction sheave is installed on the towing machine, and hoist ropes is wrapped on traction sheave and the track adjusting wheel; The load-carrying operating unit comprises car and counterweight, and the hoist ropes two ends connect car and counterweight respectively; Be characterized in: described load-carrying operating unit also is provided with some guide ropes and fixed form up and down, and the two ends of described guide rope are connected on two peripheries of fixed form up and down at least, and car and counterweight pass guide rope through the boots of leading of its upper and lower periphery; It also is provided with safety wheel and safety rope, safety wheel respectively with traction sheave, the coaxial setting of track adjusting wheel, through bearing installation, safety rope is wrapped on the safety wheel, the two ends of safety rope are separately fixed on car and the counterweight.
The present invention can be installed on the building and use, and when being installed on the building, actuating unit is installed in hoistway top, and the load-carrying operating unit is installed in the hoistway, and level is installed cooresponding down fixed form up and down respectively in the bottom of hoistway top and hoistway.The present invention also can adhere to be installed on the building and uses, and only needs a building to get final product for it provides rational support.The present invention also can use on the building ground, for the building ground provides service.The present invention also can be used for other occasion applicatory.
Technical matters to be solved by this invention can also further realize through following technical scheme.Above-described trackless lift is characterized in: up and down establishing mounting hole on the fixed form, the two ends of guide rope are connected on two peripheries of fixed form up and down through mounting hole respectively at least.
Technical matters to be solved by this invention can also further realize through following technical scheme.Above-described trackless lift is characterized in: tension device is installed on guide rope.
Technical matters to be solved by this invention can also further realize through following technical scheme.Above-described trackless lift is characterized in: establish arc groove on the safety wheel, safety rope is wrapped on the arc groove.
Technical matters to be solved by this invention can also further realize through following technical scheme.Above-described trackless lift is characterized in: on safety rope and hoist ropes, wire holder is installed, wire holder connects velocity limiter and links with velocity limiter.
On safety rope and hoist ropes, wire holder is installed, wire holder and velocity limiter interlock.
Technical matters to be solved by this invention can also further realize through following technical scheme.Above-described trackless lift is characterized in: the described boots of leading are cylindrical-shaped structure.
During use, drive traction sheave after towing machine (or passing through retarder) speed change and rotate, lean on hoist ropes and the fricative tractive force of traction sheave, realize the up-down of car and counterweight, car moves in the scope of guide rope delineation; When elevator exceeds the speed limit, exceed the speed limit when arriving the velocity amplitude of velocity limiter action, the action of machine room velocity limiter drives wire holder work, and clamping hoist ropes and safety rope make elevator out of service, reach overspeed protection; When hoist ropes breaks when falling, the car tenesmus, the action of machine room velocity limiter drives wire holder work, and the fastening safety rope makes elevator out of service, satisfies national standard elevator overspeed protecting and fall arrest are protected requirement.
The present invention has the following advantages: 1, guide rope substitutes guide rail and play the guiding role, and the intensity of well enclosure is not required basically, has reduced the civil engineering cost; 2, cancelled rail brackets and guide rail, reduced the hoistway area, villa elevator, foreign material ladder and building hoist have been had promotional value, widened aging blocks and set up the feasible of elevator; 3, adopt the guide rope installation method, need not in hoistway, to set up scaffold, elevator is installed fast, and debugging is convenient, and productive costs is low, and the operation noise is little; 4, on traction sheave and track adjusting wheel are coaxial, safety wheel is installed, safety rope twines on the safety wheel, and safety wheel is free to rotate; Safety rope does not stress on safety wheel during normal the operation, does not produce wearing and tearing, when hoist ropes is disrumpent feelings; Elevator quickens to glide, and the action of machine room velocity limiter drives wire holder fastening safety rope and makes elevator out of service; Safety rope and hoist ropes termination are not fixed on the same device, and safety performance further improves; 5, the mounting hole on the fixed form makes things convenient for the installation of guide rope, has improved the setting accuracy of guide rope.
