Description

Elevator

Technical field

This patent relates to elevator.

Background technology

The installation situation of existing elevator is:

1. when the civil engineering of elevator hoistways, every about 2 meters, laying embedded iron or cast concrete collar tie beam on the well enclosure.

2. when cage guide being installed, set up scaffold at hoistway earlier.

3. weld rail brackets in all embedded irons or cement concrete collar tie beam.

4. heavy cage guide one is saved lifting to each rail brackets from bottom to top.

5. a section meticulous accent is than squareness and parallelism.

6. Room door is fixing in the wall punching with screw.

7. for increasing the power-handling capability of towing machine, have to the machine frame height, to increase the cornerite of steel rope on traction sheave, cause machine room height too high.

Its defective:

1. civil engineering complexity, the cost height.

2. aloft work on the scaffold, dangerous high.

3. the rail brackets welding is made and the cost of installation height.

4. guide rail manufacturing and cost of installation height.

5. Room door is installed and is adjusted difficulty, operation danger.

6. elevator(lift) machine room towing machine installation dimension height, machine room height is too high.

Summary of the invention

The technical matters that the present invention solves: in order fundamentally to solve the civil engineering cost height of existing product, make the cost of installation height, dangerous high defective is installed, the present invention proposes a kind of brand-new elevator.

The technical solution adopted for the present invention to solve the technical problems is: at the upper and lower side of elevator hoistways the steel rope of some is installed vertically, in order to guide the operation of lift car or counterweight, to replace existing modular elevator rail.Elevator rope is vertically mounted on the position at four angles of car respectively, prevents that effectively elevator is because carrying askew partially that skewness produces.And then multi-section elevator shared is installed is overlapped hoistway, guide rail, Room door, control housing and machine room.Room door takes to clamp string dress mode, has simplified the complex installation program dramatically.Safety device at the bottom of sedan-chair top safety pole and the sedan-chair has reduced the danger in construction and the use.Elevator hoistways top and pit arrange arrester wires, and elevator is played certain buffer action.

The invention has the beneficial effects as follows: the accident risk that can greatly reduce civil engineering cost, elevator manufacturing cost, cost of installation and construction; And can realize many elevators of operation on the same guide rail.

The specific embodiment

1, the installation of car hoist ropes: at the upper and lower side of elevator hoistways the steel rope of some is installed vertically, in order to guide the operation of lift car or counterweight, to replace existing modular elevator rail.Elevator rope is vertically mounted on the position at four angles of car respectively, or with lifting surface form lifting (be that a plurality of lifting points constitute lifting surfaces with triangle or polygonal summit), can prevent effectively that elevator is because of uneven produce askew partially of load distribution.

2, the method for many elevators of operation on the same guide rail: selects suitable lifting position, makes between the hoist ropes of many elevators to keep certain distance, can be implemented under the microcomputer-based intelligent control same guide rail realize subregion or simultaneously about operation.

3, Room door mounting means: adopt the mode clamp, Room side wall outer panel also makes a layer door gear be connected with bank on the mode of clamping and lading door dill and the Room door, uses extremely every layer doorway, the Room of steel rope integral hoisting after assembling again.Easy for installation, saved check and correction and bolt the inconvenience that the adjustment difficulty is brought has been installed.

4, the elevator control cabinet integrated circuit: complexity in original elevator control cabinet is connect distribution assemble circuit card, line clear, simple to operate, popular resolution height.No technical requirements to operating personal.

5, the installation of car safety device: safety pole is installed on the sedan-chair top, and safety device is installed at the bottom of the sedan-chair, adds safety barrier one in the sedan-chair top bit, and the toeguard position adds a safety switch at the bottom of sedan-chair.During the operation of elevator accident, this device action makes elevator out of service.Effectively prevent the unexpected operation of elevator, the personnel that cause shear injures and deaths.Improved the safety performance of elevator.

6, elevator inspection travel alarming device:

A. the elevator normal condition is pinned door open button, presses 1 choosing layer button for several times, enters inspecting state automatically, closes behind the door, and operation downwards is 2.3 meters automatically, sends after the parking always and drips-----sound.Whenever abnormal running sedan-chair top buzzer phone sends drips--dripping---caution sound.

B, elevator have inspecting state to enter normal condition, drip earlier when starting operation----drip----drip-----, after 3 times sound cautions, can start and proofread and correct operation.

When c, elevator normally moved, buzzer phone dripped----, dripped----and rang 2.

7, the installation of arrester wires: at elevator hoistways top and pit part arrester wires is installed, the impulsive force when slowing down deceleration of elevator forces slowly elevator, can dwindle the space on the end, hole and machine top.

8, the layout of towing machine, traction fag end, bearing beam is installed: hoist ropes is directly installed on the lower aerofoil of H section steel beam, and steel rope installations that be in the shape of the letter V centered by car, and installation like this also can be saved compensated chain.Bearing beam is only established two, connects simply, and easy to operate, towing machine is directly installed on the H section steel beam.Under same operating mode, novel towing machine structure cornerite is almost 180 degree, effectively increases the towing machine power-handling capability.The elevator(lift) machine room height is 1.5 meters only in the new structure, and maintenance is easy to install and maintain.

9, the guide rail installation method: new sequence of erection, to hang oneself to the upper strata after lower floor is good and sound, unsettled hanging can meticulous adjustment squareness and the sense of equilibrium of easier lifting.

10, pre-embedded anchoring bolts directly is installed in guide rail on the bolt, complicated support need not be installed, simple operation.
