Detailed Description

In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1-3, a heavy-duty goods elevator with an oversized car comprises a car 1, a traction wheel 2 and car guide wheels 3 arranged on the left side and the right side of the top of the car, wherein the front part and the rear part of the bottom surface of a car frame of the car are provided with four car frame bottom rope wheels 4, and the end part of a traction steel wire rope 13 extending downwards along the traction wheel is wound and then upwards fixed on a rack 5 through a left rear car frame bottom rope wheel, a left front car frame bottom rope wheel, a left car guide wheel, a right front car frame bottom rope wheel and a right rear car frame bottom rope wheel in sequence. A suspension system with a traction ratio of 4: 1 is adopted, a traction steel wire rope bypasses the bottom of the same car frame twice, and rope wheels at the bottom of the car frame are distributed at the front part and the rear part of the car, so that the front part and the rear part of the car frame can be prevented from overturning, and the inclination of the car caused by unbalance loading can be effectively prevented.

The embodiment of the utility model provides an in, the car frame all includes upper beam 6 and underbeam 7, and through 8 interconnect in the straight roof beam as an organic whole between the lateral part of upper beam and underbeam, constitute firm rigid frame, the car is located inside the car frame, and the upper beam passes through elastic construction with the upper end and the lower extreme of car respectively with the underbeam and is connected.

The embodiment of the utility model provides an in, this elastic construction is spring 9, and the spring has fine cushioning effect, alleviates elevator high-speed operation, frequent flat bed brake and loads and unloads the upper and lower vibration and the shake phenomenon that the restart brought.

In the embodiment of the utility model, the car frame is installed in the well 10, six guide rails 11 are symmetrically installed on the left side and the right side of the well, the car frame moves up and down along the six guide rails under the traction of the traction steel wire rope to complete the vertical transportation task, the upper end and the lower end of the straight beam of the car frame are respectively provided with a guide shoe, the guide shoes are fastened on the guide shoe fixing plates of the upper beam and the lower beam of the car frame, and the guide shoes at the upper end and the lower end of each straight beam are in sliding fit with the guide rails which are at the same side and correspond to each; the guide rails are all mounted on a guide rail bracket 12.

The embodiment of the utility model provides an in, straight roof beam is the same with guide rail quantity, position one-to-one. The car area of a heavy-duty freight elevator is generally large, and the larger the car depth, the larger the bending moment that the car guide rails are subjected to. Once the stress point and the load position are deviated during loading, the swinging and twisting of the car in the horizontal direction are more serious, the bending moment borne by the car guide rail is multiplied, and the friction force between the guide rail and the guide shoe is increased; the wear gap sharply increases, creating a vicious circle. The car is limited to be twisted by the six guide rail structures, the six guide shoes on the upper beam of the car frame and the six guide shoes on the lower beam of the car frame are respectively arranged on two horizontal planes, and a certain distance exists between the two horizontal planes, so that the whole car frame is very stable, the phenomena of shaking and twisting cannot occur, and the abrasion gap is not easy to generate. Therefore, the six-rail structure is very important for the heavy goods elevator.

A working method of an oversized lift car heavy-load goods elevator is carried out according to the following steps: the traction steel wire rope drives the car frame to move up and down, the traction steel wire rope bypasses the bottom of the same car frame twice, and rope wheels at the bottom of the car frame are distributed at the front part and the rear part of the car, so that the front part and the rear part of the car frame can be prevented from overturning, and the inclination of the car caused by unbalance loading can be effectively prevented.

The embodiment of the utility model provides an in, the operation in-process about the car frame, the boots that lead at both ends all with homonymy and corresponding guide rail sliding fit about every straight beam, six guide rails have restricted the car and have twistd reverse, the wearing and tearing clearance is difficult to produce.

The utility model discloses not be limited to above-mentioned best mode, anyone is in the utility model discloses an it can all draw other various forms's super large car heavy load goods lift to enlighten. All the equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
