Description

Technical Field

[0001] This utility model relates to the field of freight elevator chassis technology, and in particular to a torsion-resistant, high-load-bearing freight elevator chassis structure. Background Technology

[0002] With the booming development of the industrial and logistics sectors, the application of heavy-duty freight elevators is becoming increasingly widespread. The traditional freight elevator chassis, constructed with 45mm angle steel, is gradually revealing its insufficient torsional resistance. Facing the growing demand for transporting heavy, irregularly shaped goods with uneven load distribution (e.g., goods are not placed in the center of the chassis, but rather in a corner or on one side), the inherent cross-sectional characteristics of 45mm angle steel, with its small centroidal distance, result in a low torsional section modulus. This makes it difficult to efficiently disperse torsional stress, causing the chassis to easily twist and deform during operation, affecting the stability of the elevator car, and even endangering the safety of goods and equipment. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a heavy-duty freight elevator chassis structure that uses a combination of channel beams and angle beams to resist torsion.

[0004] A torsion-resistant heavy-duty freight elevator chassis structure designed for this purpose includes a chassis body. The lower surface of the chassis body is provided with a longitudinal beam module and a transverse beam module. The transverse beam module includes a set of angle beams and two sets of channel beams. The two sets of channel beams are respectively arranged on the front and rear sides of a set of angle beams.

[0005] A set of angle beams includes multiple angle beams arranged sequentially along the front-to-back direction;

[0006] A set of channel beams consists of multiple channel beams arranged sequentially along the front-to-back direction.

[0007] Preferably, the longitudinal beam module includes multiple longitudinal beams arranged sequentially in the left-right direction.

[0008] Preferably, the longitudinal beam has a groove-shaped structure.

[0009] Preferably, the height of the angle beam and the channel beam is A; the thickness of the angle beam and the channel beam is B.

[0010] A≥100mm;

[0011] B≥5mm.

[0012] Preferably, the height of the longitudinal beam is C; the thickness of the longitudinal beam is D;

[0013] C≥100mm;

[0014] D≥5mm.

[0015] Preferably, A = 140 mm; B = 5 mm.

[0016] Preferably, C = 140 mm; D = 5 mm.

[0017] Preferably, the longitudinal beam is provided with evenly distributed openings.

[0018] Compared with existing technologies, the crossbeam module of this invention includes one set of angle beams and two sets of channel beams; the two sets of channel beams are respectively arranged on the front and rear sides of one set of angle beams. This invention uses a combination of angle beams and channel beams, achieving both low cost and high torsional load resistance. The channel beams on both sides play a role in resisting torsion when the chassis is under unilateral load. The angle beam located in the center position can reduce the overall manufacturing cost of the chassis. Attached Figure Description

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0032] See Figures 1-5A torsion-resistant, high-load-bearing freight elevator chassis structure includes a chassis body 10. The lower surface of the chassis body 10 is provided with longitudinal beam modules 20 and transverse beam modules 30. The transverse beam modules 30 include a set of angle beams 310 and two sets of channel beams 320. The two sets of channel beams 320 are respectively arranged on the front and rear sides of the set of angle beams 310. The set of angle beams 310 includes multiple angle beams 310 arranged sequentially in the front-rear direction; the set of channel beams 320 includes multiple channel beams 320 arranged sequentially in the front-rear direction. This invention uses a combination of angle beams and channel beams, achieving both low cost and torsion resistance with high load-bearing capacity. The channel beams on both sides play a torsion-resistant role when the chassis is under load on one side. The angle beam located in the center position reduces the overall manufacturing cost of the chassis.

[0033] Furthermore, the longitudinal beam module 20 includes multiple longitudinal beams 210 arranged sequentially along the left-right direction. The longitudinal beams 210 have a channel-shaped structure.

[0034] See Figure 4 The height of the angle beam 310 and the channel beam 320 is A; the thickness of the angle beam 310 and the channel beam 320 is B; A≥100mm; B≥5mm.

[0035] Furthermore, A = 140mm; B = 5mm. Both the angle beam 310 and the channel beam 320 are formed by bending 5mm sheet metal.

[0036] See Figure 5 The height of the longitudinal beam 210 is C; the thickness of the longitudinal beam 210 is D; C ≥ 100 mm; D ≥ 5 mm. From a mechanical perspective, compared to traditional 45# angle steel, the centroid distance of the channel-shaped longitudinal beam 210 is significantly increased. Measured by the formula for calculating the moment of inertia of a section, $I = \int y^{2}dA$, the channel-shaped structure can distribute more material away from the neutral axis, resulting in a significant increase in the moment of inertia. This enhances the longitudinal beam's resistance to bending and torsional deformation, thus constructing a stable longitudinal support system for the chassis.

[0037] Furthermore, C = 140mm; D = 5mm. All longitudinal beams 210 are made of 5mm sheet metal bent into shape.

[0038] See Figure 3 The longitudinal beam 210 is provided with evenly distributed openings 220.

[0039] See Figure 2Both the angle beam 310 and the channel beam 320 are segmented structures, meaning that a single angle beam 310 or channel beam 320 is composed of multiple segments, and both ends of each segment are welded and fixed to the longitudinal beam 210. With this structural design, when encountering torsional forces, according to the principle of force transmission and decomposition, the crisscrossing sheet metal structure disperses the torque to various connection nodes, avoiding stress concentration in a single area. It's like breaking down a powerful torsional force into multiple small components, evenly distributing them across the entire chassis.
