Description

Special equipment for elevator installation

technical field

The invention relates to the technical field of elevator installation, in particular to a special equipment for elevator installation.

Background technique

In the field of elevator installation engineering, more and more attention has been paid to the installation without scaffolding. However, the installation without scaffolding in China mainly uses the bottom of the car as a working platform to complete the installation work inside the elevator guide rail and other wells. During the operation, the brand-new car equipment, traction machine, traction wire rope and other components that should be provided to customers As an on-site construction tool, this practice of detrimental to the interests of users is controversial. Adopting special equipment to complete the elevator installation for this reason is the development direction of elevator installation work.

In the elevator installation work, the installation of the elevator guide rail is the work with the largest workload and the most relevant work safety in the elevator installation project. However, the traditional elevator installation technology basically does not consider the continuous installation of the elevator guide rails. For the important work of transporting elevator guide rails to higher floors, the elevator guide rails (including counterweight guide rails) are transported layer by layer manually. Manual handling is labor-intensive, the operation time is long, and the progress of the project is slow.

Due to structural reasons, the hanging basket in the traditional elevator installation project can only be used as a working platform for moving up and down, and it cannot transport the elevator guide rails to higher floors. As a result, in the elevator installation work, the practice of manually transporting the elevator guide rails has not been improved for a long time and cannot be adapted to the elevator. The actual needs of rail installation work.

Contents of the invention

The purpose of the present invention is to address the deficiencies of traditional elevator installation technology, and provide an elevator guide rail or counterweight guide rail that does not require manual handling and does not use elevator accessories in advance to damage the interests of customers, which can reduce the labor intensity of workers, and is safe and practical. High-efficiency elevators are installed with special equipment.

The purpose of the present invention can be achieved. The special equipment for elevator installation of the present invention includes a personnel operation lifting system, a working platform with an upper and lower communication structure in the personnel operation lifting system, and a lifting drive device. The special equipment for elevator installation of the present invention is characterized in that: the special equipment for elevator installation also includes: A guide rail hoisting system suspended on the top of the hoistway is provided, and the guide rail hoisting system includes a horizontal track installed on the top of the elevator shaft and parallel to the connecting direction of the two elevator guide rails and a lifting and translation device hooked on the horizontal track.

The special equipment for elevator installation of the present invention, wherein the guide rail lifting and translation device is composed of a lifting mechanism and a translation mechanism, and the guide rail lifting and translation device has a linear reciprocating motion track on the horizontal track through the translation mechanism, and the guide rail lifts The two ends of the traction wire rope or chain of the hoisting mechanism of the translation device are respectively connected to a guide rail spreader, and each of the two guide rail spreaders has a rectilinear lifting motion track opposite to each other along the height direction of the hoistway.

The special equipment for elevator installation of the present invention, wherein the central parts of the upper and lower working platforms in the personnel operation lifting system are symmetrically opened with a through hole, and the movement track of the traction steel wire rope or chain is in the through hole, so The lifting drive device in the personnel operation lifting system is arranged in the vertical direction of the car guide rail connection center.

The special equipment for elevator installation of the present invention is different from the prior art in that the special equipment for elevator installation of the present invention is equipped with a set of guide rail lifting and translation devices that can vertically lift and horizontally move the elevator guide rails on the horizontal track . When the elevator guide rail is lifted, it can smoothly pass through the through hole of the work platform without being restricted by the work platform. The guide rail lifting and translation device can be used to easily lift and translate the elevator guide rail to the installation position and carry out the installation work easily and smoothly, which reduces the heavy labor of manually transporting the elevator guide rail to the high-rise building, and improves work efficiency and project progress. The special equipment for elevator installation is also suitable for elevator installation operations that require installation of counterweights.

The special equipment for elevator installation of the present invention will be further described below in conjunction with the accompanying drawings.

Description of drawings

Fig. 2 is a schematic diagram of the section K-K in Fig. 1 (installation position of the lifting drive device).

Detailed ways

As shown in Figure 1, the special equipment for elevator installation of the present invention includes a personnel operation lifting system, working platforms 7 and 9 with upper and lower communication structures in the personnel operation lifting system, and a lifting drive device 8. The special equipment for elevator installation is also equipped with a guide rail lifting system suspended on the top of the hoistway. The guide rail hoisting system includes a horizontal rail 1 installed on the top of the elevator shaft and parallel to the connecting direction of the two elevator guide rails, and a lifting and translation device 2 hooked on the horizontal rail 1 .

The guide rail lifting translation device 2 is composed of a lifting mechanism and a translation mechanism. The guide rail lifting translation device 2 has a linear reciprocating motion track on the horizontal track 1 through a translation mechanism, and can move in parallel on the horizontal track 1 . The hoisting mechanism is a traction type hoisting mechanism that lifts the elevator guide rail 5 by traction wire ropes or chains 3 . The two ends of the traction wire rope or the chain 3 of the hoisting mechanism of the guide rail lifting translation device 2 are respectively connected with a guide rail hanger 4 . The two guide rail hangers 4 each have opposite linear lifting motion trajectories along the height direction of the hoistway. When one end of the traction wire rope or chain 3 lifts the elevator guide rail 5 upward, the other end that is not loaded moves downward.

The upper and lower working platforms 7 and 9 in the personnel operation lifting system can provide 2 work stations up and down simultaneously when the elevator guide rail is installed, so as to improve work efficiency. The central parts of the upper and lower working platforms 7 and 9 are respectively provided with a through hole 11 symmetrically. The trajectory of the traction wire rope or chain 3 is in the through hole 11, the through hole 11 is the passage of the traction wire rope or chain 3, and the traction wire rope or chain 3 can move up and down in the through hole 11, so as to pass through the guide rail. Tool 4 promotes elevator guide rail 5. In the personnel operation lifting system, a ceiling 6 is provided on the top of the upper working platform 7, and the middle part of the ceiling 6 also has a through hole similar to the working platform. After removing roof 6, working platform can be used for assembling car.

As shown in Figures 1 and 2, the bottom of the lower working platform 9 is at least provided with a guide wheel 10 on both sides of the elevator guide rail 5 direction, and the guide wheels 10 are fitted with the elevator guide rail 5 and roll along the elevator guide rail 5. The lifting drive device 8 in the personnel operation lifting system is arranged in the vertical direction of the car guide rail connecting line center.

As a special case, according to the cross-sectional size of the hoistway, the guide rail lifting system can remove the translation mechanism in the horizontal track 1 and the lifting translation device 2, and only retain the guide rail lifting mechanism and hang it on the top of the hoistway.
