Description

A hanging basket for installing and maintaining the guide rail of a single lifting point elevator

technical field

The utility model relates to a hanging basket, in particular to a hanging basket for installation and maintenance of elevator guide rails with a single suspension point.

Background technique

As known, the elevator guide rails are heavy and long, so the installation of the elevator guide rails is very difficult. At present, the method of installing elevator guide rails is mainly to use the elevator car as a power platform, and use scaffolding to build a double-layer platform on the car. The double-layer platform is used to carry heavy objects such as relevant staff, work tools and elevator guide rails . Since the platform built with scaffolding is relatively simple and has no corresponding protection measures, there are great potential safety hazards during normal operation.     

In addition, since the double-deck platform is built on the top of the car, when installing the guide rails, all the weight on the platform is borne by the car, and there are no effective protection measures for the car body during this process, so this installation The method will cause certain damage to the car itself, does not conform to the standardization of the installation and use of the elevator, and cannot guarantee the personal safety of the construction personnel.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a hanging basket for installing and maintaining the guide rail of a single-suspended elevator, which is composed of a bottom bracket, an intermediate platform and a ceiling. The inverted triangular guide frame on both sides is connected to the upper and lower beams of the inverted triangular guide frame, and the tie rods connected to the upper and lower beams; the middle platform is spliced by the bottom plate, four railings and four vertical pipes. The intermediate platform is installed on the inverted triangular guide frame, and a hoist and a safety lock are also installed on the intermediate platform; the ceiling is installed on the vertical pipe of the intermediate platform, and a travel switch is arranged on the ceiling.

Preferably: there is a gap in the middle of the bottom plate, and a hoist mounting frame is provided at the gap, and the hoist mounting frame is connected to the upper beam through the gap, and the hoist and the safety lock are both installed on the hoist mounting frame.

Preferably: the safety lock adopts a centrifugal safety lock.

Preferably: each of the inverted triangular guide frames is provided with a rail locking device, and the rail locking device is connected to a rail locking device switch arranged on the hoist installation frame through a wire rope.

Preferably: the inverted triangular guide frame is provided with two pairs of guide wheels respectively, and the guide wheels are respectively installed at both ends of the middle pillar of the inverted triangular guide frame.

Preferably: the ceiling is an assembled ceiling, and two pieces of aluminum welded parts are spliced obliquely to form an inverted V-shaped slope with an opening downward.

Preferably: the bottom plate is formed by splicing two aluminum plates.

The beneficial effects of the utility model are: the hanging basket can be suspended in the elevator shaft through the suspension mechanism, which is convenient for the installation and maintenance of the elevator guide rail, and avoids damage to the car; The hidden danger of platform tilt caused by synchronization; at the same time, the pull rod on the bottom bracket ensures the uniformity of the force on the platform, effectively protects the basket body, and ensures the stability of the platform when it runs up and down. When the hanging basket moves to the designated position, The safety and stability when installing the guide rail is enhanced by the rail lock.

The utility model has a reasonable structural design, not only can improve the installation efficiency of the guide rail of the elevator, is convenient for the maintenance of the elevator, but also can ensure the personal safety of construction personnel and improve the safety factor.

Detailed ways

The specific implementation of the present utility model will be further described in detail below in conjunction with the accompanying drawings and preferred solutions.

Shown in conjunction with accompanying drawing 1 and Fig. 2, can illustrate the concrete structure of the present utility model, this single suspension point elevator guide rail installation and maintenance hanging basket is made of three parts, is respectively bottom support, intermediate platform and ceiling. The bottom bracket includes two inverted triangle guide frames 1, an upper beam 2, a lower beam 3, and two pull rods 4; the two inverted triangle guide frames 1 are connected by bolts to the upper beam 2 and the lower beam 3, and the pull rod 4 One end of the upper beam is connected to the end section of the lower beam 3 by bolts, and the other end is connected to the middle section of the upper beam 2 by bolts. Two tie rods 4 are connected with the upper and lower beams to form an inverted V-shaped structure with openings. The middle platform is spliced by base plate 5, four railings 6 and four vertical pipes 7, railings 6 can be installed around the base plate 5 by bolts, and vertical pipes 7 are respectively installed in four corners surrounded by railings 6, Hoist 8 and safety lock 9 are installed in the middle of this platform. The ceiling 10 can be connected with the four vertical pipes 7 by bolts, and the ceiling 10 is also provided with a travel switch 11 .

Embodiment: The intermediate platform in this embodiment is made of aluminum material and installed on the upper pillar of the inverted triangle guide frame 1. The platform can be spliced by two bottom plates 5, four railings 6 and four vertical pipes 7. , there is a gap in the middle of the bottom plate 5, a hoist mounting frame 12 is installed at the gap, the hoist mounting frame 12 is connected with the upper beam 2 and the pull rod 4 through the gap, the hoist 8 and the safety lock 9 are all installed on the hoist mounting frame 12 superior.

A rail lock 13 is provided on the middle pillar of the inverted triangle guide frame 1 in the present embodiment, and two rail locks 13 are respectively connected with the rail lock switch 14 that is installed on the hoist installation frame 12 by wire ropes. A pair of guide wheels 15 are respectively installed at the two ends of the middle pillar of inverted triangle guide frame 1, totally four pairs of guide wheels 15. The ceiling 10 is an assembled ceiling, which is formed by oblique splicing of two steel plates to form an inverted V-shaped slope with an opening downward.
