Description

The method of elevator installation and the lifting system used in it

technical field

The invention relates to a method for elevator installation. The invention also relates to an elevator-mounted hoisting system for use in the installation of elevators.

Background technique

The current traditional elevator installation method is to use the installation process of scaffolding, that is, a fixed scaffolding work platform is set up every 1.8 meters or so in the elevator shaft to be installed, and runs through the entire shaft. Then, according to the different installation positions of the various parts of the elevator, the scaffolding working platform in different positions is selected as the construction platform for operation. After the elevator components in the hoistway are basically installed, remove the scaffolding to adjust and debug the elevator. The traditional installation process makes the consistency of each working platform poor, and it is difficult to provide sufficient lighting for each construction area in the hoistway. The movement when working on different construction platforms mainly depends on the installation personnel to climb or take the stairs, thus wasting a lot of time. time and physical strength of the installer. In order to reduce handling, elevator components cannot be stacked together. It is difficult to strictly control the safety protection of the three-dimensional construction in the hoistway, and the components cannot be installed in place at one time. In addition, there will be a lot of adjustment work and a series of other problems after the scaffolding is removed.

The method for elevator installation of the present invention specifically comprises the steps:

(1) According to the business design drawing of the elevator that needs to be installed in the corresponding well, set the sample frame on the floor of the machine room, determine the exact installation position of all relevant components of the elevator, and carry out the parts in the machine room according to the requirements of the sample frame Positioning and installation, the components in the machine room include the traction machine 1, the guide wheel 3, the traction base beam 4, the control panel 17 and the speed limiter 18, and confirm and correct the reserved holes on the floor of the machine room;

(2) The car guide rails 20 after the two rows are connected in sequence are hoisted by the hoisting equipment and fixed on the floor of the machine room, so that the two ends of the guide rails in the whole row are reliably temporarily fixed; The counterweight frame guide wire rope 7 in the counterweight running direction, and then a buffer 14 and a tensioning pulley 13 are installed at the bottom of the hoistway;

(3) Assemble the car frame 22 at the bottom of the hoistway to form a mobile platform. At the same time, the counterweight frame 5 and the counterweight iron 6 are assembled on the rear side of the bottom layer, and the assembled counterweight frame 5 is guided by the counterweight frame The guiding of steel wire rope 7 is promoted to the top floor of hoistway with hoisting equipment;

(4) Install the traction machine wire rope 2, make the traction machine wire rope 2 pass through the transition of the traction machine 1, and connect the assembled working platform with the counterweight frame 5 to form a traction-driven balance system, and then the overspeed governor The steel wire rope is installed in place to make the safety protection of the overspeed governor 18 and the safety gear linkage take effect, and the warning light 15, the cable reel 16, the running cable 25 and the manual control panel 23 are installed in place, so that the platform can be controlled on the lifting platform. Move up and down for operation; install the super-level limit switch 19 in place to avoid sinking and topping when the platform is running;

(5) Carry out the wiring and debugging of the maintenance operation of the temporary mobile platform, check whether all safety protections are effective, install the protective tube 9 in place, and then install the fixed parts in the shaft through the up and down operation of the platform.

The present invention also includes a hoisting system installed with an elevator, which includes the traction device of the elevator, the counterweight frame and the car frame, the car frame 22 includes an upper platform 10 and a lower platform 12, in the Around the upper platform 10 of the car frame 22 and around the lower platform 12, guardrails 11 are installed, and the top of the guardrail 11 of the upper platform 10 is provided with a protective top plate 8, and the protective top plate 8 is connected to the car frame. 22 is provided with a longitudinal protection tube 9, the traction steel wire rope 2 of the elevator traction device passes through the protection tube 9 and is connected with the car frame 22, and the car frame 22 is provided with a control panel for controlling the lift 23. The car frame 22 is also provided with a power supply box for use during construction.

Compared with the traditional installation process, the main difference of the present invention is that in the original installation process, the installer repeatedly climbs on the temporary platform of the scaffold that runs through the shaft, and after basically installing all the elevator components in the shaft, the scaffold is removed for debugging. ,Adjustment. However, the present invention utilizes the two inherent working platforms of the ground floor and the machine room, i.e. the civil construction floor; the relevant components for the operation and movement of the elevator are installed and set, so that a set of lifting platforms that can temporarily move vertically in the elevator shaft can be realized in advance. , use this platform to install all the fixed parts of the hoistway and landing. It can completely overcome the poor consistency of the scaffolding installation process, lighting difficulties, wasting a lot of time and manpower, the elevator components cannot be stacked together, the safety protection of the three-dimensional construction in the shaft is difficult to strictly control, and the components cannot be installed in place at one time. After dismantling, there will be a lot of adjustment work and other issues. The invention provides a double-layer stable platform, which can ensure that the working platform has sufficient construction lighting. The vertical movement of personnel in the shaft and the handling of parts can be realized by the transportation of the platform. The parts do not need to be layered in advance and can be concentrated It is stacked and easy to manage. The benchmark or reference size for the installation of many components can be set on the mobile platform. The rate of components being installed at one time is greatly improved, and after the installation is completed, the lifting system does not need to be completely disassembled, because the lifting system uses the elevator. It is composed of some parts. After the use is completed, only the protective fence and the protective roof on the lifting platform are removed, and then the car frame can be directly assembled to form the elevator car.
