Description

Technical Field

[0001] The utility model relates to an improved sill structure of a freight elevator, in particular to a folding steel sill for a freight elevator. Background Art

[0002] A freight elevator is an elevator device used for carrying goods. Unlike common passenger elevators, freight elevators have a large space and high load requirements. Therefore, the structure at the bottom of the elevator requires high strength. The sill is the ground foundation structure installed below the elevator door opening. It is used to guide the elevator door opening and form a part of the ground support structure. Therefore, it requires higher strength. Unlike passenger elevators, the sill of a freight elevator is generally made of steel, commonly flat steel, cast iron, etc., but such materials generally have a fixed shape and are not easy to adjust during supporting installation. Further fine processing is required, so the processing cycle is long, which is not conducive to production arrangements. Therefore, structural improvements are needed. Utility Model Content

The trough panel is a trough structure flush with the ground, the upward sill trough structure is used to correspond to the slider structure of the elevator door, the plate is bent and formed, the structure has good strength, good load-bearing capacity for cargo, and is not easy to deform. The bracket plate is the supporting part of the trough structure, which can limit the deformation of the trough panel and extend the service life of the structure. It is fixed by the mounting plate to the car bottom structure or the wall, and the strength of the structure is reliable.

[0005] Furthermore, the trough panel is formed with an angled groove at the fold line, and the trough panel is bent to form a right angle according to the angled groove. The angled groove can achieve a better right angle effect, reduce the arc deformation of the bend, and the angled groove can improve the forming efficiency of the bend.

[0006] Furthermore, the bracket plate is provided with welding holes, which are provided at positions corresponding to the sill groove structures of the trough panel, and welding points are formed in the welding holes for welding and fixing the trough panel and the bracket plate, and the welding holes are arranged at long intervals along the entire length of the sill. The welding holes are used to contact and weld the trough panel and the bracket plate from the bottom, and the welding spacing is uniform and the structure is reliable.

[0007] Furthermore, the bracket plate is provided with a mounting hole, which is opened at a position corresponding to the position between the sill groove structure of the slot panel, and the mounting hole is composed of an enlarged hole and a long hole, wherein the edge of the enlarged hole is close to and welded to the bottom of the slot panel, and the distance between the long holes is set corresponding to the diameter of the fixing bolt, and there are multiple mounting holes, which are arranged at intervals. The mounting hole is used to install bolts, etc., wherein the edge of the enlarged hole can contact the slot panel and can be used for welding and fixing, and the head of the bolt can enter through the enlarged hole and move into the long hole.

[0008] Furthermore, the trough panel and the bracket plate use 3-5 mm steel plates as the bent plate materials. The material cost of the plate is low, it is convenient to form, the overall manufacturing cost is low, and it is conducive to improving economic benefits.

[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is a sill structure for a freight elevator, which is a sill structure formed by bending a steel plate. It has good rigidity and structural strength, is suitable for use in a cargo environment, can withstand pressure, is not easily deformed, has a long service life, and does not affect the normal operation of the elevator.
