[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] The specific technical solution of this utility model is as follows:

[0018] In one specific embodiment, such as Figure 1 As shown, this utility model provides a car bottom structure for a heavy-duty freight elevator, including a support frame and a car bottom plate 1;

[0019] The support frame includes a transverse support beam assembly and a longitudinal support beam assembly. The longitudinal support beam assembly includes a middle longitudinal support beam 2 and two end longitudinal support beams 3. The two end longitudinal support beams 3 are both channel steels, and the slots of the two end longitudinal support beams 3 are arranged facing each other. The middle longitudinal support beam 2 is an I-beam. The transverse support beam assembly includes multiple transverse support beams 4. The middle part of the transverse support beam 4 passes through the middle longitudinal support beam 2, and the two ends of the transverse support beam 4 extend into the slots of the two end longitudinal support beams 3 respectively. The middle part of the transverse support beam 4 is welded and fixed to the flange of the middle longitudinal support beam 2, and the two ends of the transverse support beam 4 are welded and fixed to the flanges of the two end longitudinal support beams 3 respectively.

[0020] The car floor plate 1 is positioned above the support frame, and the car floor plate 1 is fixedly connected to the two end longitudinal support beams 3 by fasteners.

[0021] The above-mentioned solution: This utility model discloses a car bottom structure for a heavy-duty freight elevator. By setting a support frame including transverse support beam assemblies and longitudinal support beam assemblies, wherein the longitudinal support beam assembly includes a middle longitudinal support beam 2 and two end longitudinal support beams 3, and the transverse support beam assembly includes multiple transverse support beams 4, the overall strength and rigidity of the car bottom can be effectively improved, thereby increasing the load-bearing capacity of the car bottom and making it less prone to deformation and cracking. During the assembly of the support frame, through holes are pre-machined on the middle longitudinal support beam 2 for the transverse support beams 4 to pass through. The transverse support beams 4 are passed through the through holes on the middle longitudinal support beam 2, and then both ends of the transverse support beams 4 are respectively inserted into the slots of the two end longitudinal support beams 3. Finally, the transverse support beams 4 are fixedly connected to the middle longitudinal support beam and the two end longitudinal support beams 3 by welding, completing the assembly of the support frame. After the support frame is assembled, the car bottom plate 1 is fixedly connected to the two end longitudinal support beams 3 by fasteners, thus completing the assembly of the car bottom.

[0022] In another specific embodiment, such as Figure 1 As shown, a buffer pad 5 is provided between the support frame and the car floor 1.

[0023] The above solution is adopted: a buffer pad 5 is set to buffer the car floor 1.

[0024] In another specific embodiment, such as Figure 1 As shown, the fastener is a bolt 6, which passes through the car floor plate 1 and the buffer pad plate 5 in sequence and is then threaded to the top of the end longitudinal support beam 3.

[0025] The above solution is adopted: the car floor plate 1 and the end longitudinal support beam 3 are detachably fixedly connected by bolts 6.

[0026] In another specific embodiment, such as Figure 1 As shown, the car floor 1 is composed of multiple single panels spliced ​​together.

[0027] The above solution allows for the replacement of individual panels when the car floor 1 is partially damaged, eliminating the need to replace the entire car floor 1 and thus avoiding unnecessary waste.

[0028] In another specific embodiment, such as Figure 1 As shown, reinforcing blocks 7 are respectively provided in the slots at both ends of the longitudinal support beam 3 at the end.

[0029] The above solution is adopted: the structural strength of the end longitudinal support beam 3 is improved by setting up the reinforcing block 7.

[0030] In another specific embodiment, such as Figure 1 As shown, the transverse support beam 4 is a square tube.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
