Furthermore, the two duplicate buffers and the two car buffers are respectively fixed with a hoop plate, and two ends of each hoop plate are respectively connected with the corresponding platform component in a welding way.
Further, the thickness of the hoop plate is 16 mm.
Furthermore, any two adjacent platform components are fixedly connected through a plurality of transverse connecting strips.
Further, the cover plate and the platform plate are both made of steel plate meshes.
Furthermore, a handle is welded and fixed in the middle of the upper end face of the cover plate.
Further, the service opening is provided at the left end of the front platform member.
Furthermore, the square bracket is formed by splicing angle steels and is fixed on the wall of the well through expansion bolts.
The beneficial effects of the utility model reside in that:
the utility model discloses in, the full protection platform matches with the well size, can increase the operating space on the platform to the risk that falls personnel and part is reduced to minimumly. Simultaneously, the pit is separated into upper and lower two maintenance spaces to the full protection platform, and the apron can be opened as required and closed, through the access hole, the maintainer can descend maintenance platform below, and the personnel in upper and lower two maintenance spaces can independently operate, also can be above-below in coordination with the operation. The full protection platform mainly comprises three platform components, and the platform components can be processed and finished in a factory and transported to the site, so that the installation workload of the site can be reduced.

Detailed Description
The fully protective pit maintenance platform of the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the full protection pit maintenance platform comprises a front platform component 5, a middle platform component 6, a rear platform component 7, and a square bracket 11 (the set height is determined according to actual conditions on site) which is matched with the size of a pit and is arranged at the set height in the pit, wherein the square bracket 11 is circumferentially fixed on the wall of the pit. The front platform component 5, the middle platform component 6 and the rear platform component 7 are sequentially erected on the square bracket 11 from front to back and are fixedly connected with the square bracket 11 in a welding mode. The front platform member 5 is located at the front side of the car guide rail 2, the middle platform member 6 is located between the counterweight guide rail 1 and the car guide rail 2, and the rear platform member 7 is located at the rear side of the counterweight guide rail 1. The front platform component 5, the middle platform component 6, the rear platform component 7 and the square bracket 11 form a 'full-protection' platform together, an access hole is formed in the 'full-protection' platform, and a cover plate 8 capable of being lifted is arranged at the position of the access hole.
In this embodiment, the square bracket 11 is formed by angle steel by splicing and is fixed on the wall of the well through an expansion bolt. The access opening is provided at the left end of the front platform member 5. Anterior platform component 5, middle part platform component 6 and rear portion platform component 7 are formed by shaped steel and the concatenation of landing slab, and apron 8 and flat bed board all adopt the steel sheet net, increase the visuality between the upper and lower maintenance space, improve the efficiency of collaborative operation. In addition, a handle is welded and fixed at the middle position of the upper end surface of the cover plate 8.
At present, it is fixed through corresponding the guide rail to counter weight buffer 3 and car buffer 4, and when the car squat at the bottom, the car is very big to the buffer impact force, only leans on the guide rail can't fix the buffer completely, makes the guide rail warp easily, produces bigger destruction to elevator system. Based on this, the scheme is further improved, and comprises the following steps:
the two pairs of the heavy buffers 3 and the two car buffers 4 are respectively fixed with a hoop plate 9, and two ends of each hoop plate 9 are respectively connected with the corresponding platform components in a welding way. Still carry out fixed connection through a plurality of transverse connection strip 10 between arbitrary two adjacent platform components, transverse connection strip 10 can adopt section bars such as angle steel, square steel pipe, and the optional welded fastening platform board between adjacent transverse connection strip 10. In this embodiment, the thickness of the hoop plate 9 is 16 mm. Like this, whole maintenance platform plays the fixed action with four buffers, when car striking car buffer 4, can effectively prevent to turn on one's side, avoids the guide rail to warp.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the embodiments described above, but rather is described in the embodiments and the description only to illustrate the principles of the invention and that various changes and modifications may be made without departing from the spirit and scope of the invention, the scope of which is defined by the appended claims, the description and the equivalents thereof.
