Description

Technical Field

[0001] This utility model relates to the field of elevator car frame technology, and in particular to a heavy-duty freight elevator car frame. Background Technology

[0002] The car frame is the load-bearing structure of the elevator car, and its main function is to fix and suspend the car, ensuring its stable operation within the elevator shaft. In heavy-duty freight elevators, the car frame needs to withstand greater weight and impact forces. Therefore, compared with the car frame of a regular freight elevator, the structural load-bearing capacity requirements for the car frame of a heavy-duty freight elevator are much higher.

[0003] The existing heavy-duty cargo car frame consists of an upper frame and a lower frame, with multiple columns connecting the upper and lower frames.

[0004] The existing heavy-duty freight elevator car frame lacks a load-bearing structure, which makes the structure prone to deformation when carrying heavy goods, affecting the safety of the heavy-duty freight elevator during use. Utility Model Content

[0005] One objective of this invention is to address the lack of a load-bearing structure in existing heavy-duty freight elevator car frames. This causes the car frame to easily deform when carrying heavy loads, affecting the safety of the heavy-duty freight elevator during use.

[0006] Specifically, embodiments of this application provide a heavy-duty freight elevator car frame, comprising:

[0007] The upper frame includes at least two upper longitudinal beams symmetrically arranged in a first direction and at least two upper transverse beams symmetrically arranged in a second direction, wherein the upper transverse beams and the upper longitudinal beams are both horizontally arranged and perpendicular to each other.

[0008] The lower frame, corresponding to the upper frame, includes at least two lower longitudinal beams symmetrically arranged in the first direction, at least two lower transverse beams symmetrically arranged in the second direction, and a cargo plate arranged on one side of the lower longitudinal beams and the lower transverse beams parallel to the upper frame. The lower transverse beams and the lower longitudinal beams are both arranged horizontally and perpendicular to each other.

[0009] Multiple columns are arranged on the outer periphery of the upper frame and the lower frame and connected to the upper frame and the lower frame, with each column extending upwards towards the upper frame.

[0010] Multiple inclined tie beams, one end of which is connected to the extension of the column located in the middle of the upper crossbeam, and the other end of which is connected to the upper crossbeam on the same side; and

[0011] The lifting wheel mounting part is used to install the lifting wheel, and the two ends of the lifting wheel mounting part are respectively connected to the two columns located in the middle of the upper crossbeam.

[0012] Furthermore, the heavy-duty freight elevator frame of this utility model also includes multiple stay cables, one end of each stay cable is connected to one of the columns, and the other end is connected to the lower frame. Each stay cable and the stay beam on the same side are in the same plane.

[0013] Furthermore, the number of stay cables connected to each of the columns is an even number and is symmetrical with respect to the axial direction of the column.

[0014] Furthermore, the lower frame also includes a plurality of lower sub-beams, which are disposed on the side of the lower frame away from the upper frame and are evenly distributed along the second direction, and the lower sub-beams are parallel to the lower longitudinal beams.

[0015] Furthermore, the stay cable is connected to the lower sub-beam.

[0016] Furthermore, the lower frame also includes a plurality of lower main beams, which are disposed on the side of the lower frame away from the upper frame, and the lower main beams are parallel to the lower secondary beams.

[0017] Furthermore, each of the lower main beams is connected at both ends to two symmetrically arranged columns.

[0018] Furthermore, each of the lower main beams is provided with multiple buffers along the length of the lower main beam on the side away from the cargo plate.

[0019] The beneficial effects of this utility model are:

[0020] 1. Add a diagonal brace and connect one end of the diagonal brace to the extension of the column, and connect the other end of the diagonal brace to the upper crossbeam or upper longitudinal beam. The diagonal brace, upper longitudinal beam, and column, or the diagonal brace, upper crossbeam, and column, form a triangle. When the load on the cargo pallet is large, the diagonal brace will provide tensile force along the axis of the diagonal brace to the upper frame, enhancing the stability of the upper frame structure of the heavy-duty freight elevator.

[0021] 2. By setting a lower main beam and a lower secondary beam under the lower frame, the overall rigidity of the lower frame is enhanced, and deformation of the lower frame is prevented when the load on the cargo plate is large. Attached Figure Description

[0029] like Figure 1As shown, the heavy-duty freight elevator 100 frame of this utility model includes an upper frame 1, a lower frame 2, multiple columns 3, multiple inclined tie beams 4, and a lifting wheel mounting part 5. The upper frame 1 includes at least two upper longitudinal beams 11 symmetrically arranged in a first direction and at least two upper transverse beams 12 symmetrically arranged in a second direction. The upper transverse beams 12 and the upper longitudinal beams 11 are both horizontally arranged and perpendicular to each other. The lower frame 2 corresponds to the upper frame 1. The lower frame 2 includes at least two lower longitudinal beams 21 symmetrically arranged in a first direction, at least two lower transverse beams 22 symmetrically arranged in a second direction, and a cargo plate 6 arranged on one side of the lower longitudinal beams 21 and lower transverse beams 22 parallel to the upper frame 1. The lower transverse beams 22 and the lower longitudinal beams 21 are both horizontally arranged and perpendicular to each other. Multiple columns 3 are arranged on the outer periphery of the upper frame 1 and the lower frame 2 and connected to the upper frame 1 and the lower frame 2. Each column 3 extends upwards from the upper frame 1. One end of each of the multiple cable-stayed beams 4 is connected to the extension of the column 3 located in the middle of the upper crossbeam 12, and the other end is connected to the upper crossbeam 12 on the same side. The lifting wheel mounting part 5 is used to install the lifting wheel, and both ends of the lifting wheel mounting part 5 are respectively connected to the two columns 3 located in the middle of the upper crossbeam 12.

[0030] In the heavy-duty freight elevator frame 100 of this utility model, each column 3 is configured such that the end near the upper frame 1 extends away from the upper frame 1. A diagonal brace 4 is added, with one end connected to the extension of the column 3, and the other end connected to the upper crossbeam 12 or the upper longitudinal beam 11. The diagonal brace 4, the upper longitudinal beam 11, and the column 3, or the diagonal brace 4, the upper crossbeam 12, and the column 3, form a triangle. When the load on the cargo platform 6 is large, the diagonal brace 4 provides tension to the upper frame 1 along the axis of the diagonal brace 4, enhancing the stability of the upper frame 1 structure of the heavy-duty freight elevator frame 100.

[0031] Please refer to this again. Figure 1 The heavy-duty freight elevator frame 100 of this utility model also includes multiple inclined cables 7. One end of each inclined cable 7 is connected to a column 3, and the other end is connected to the lower frame 2. Each inclined cable 7 and its corresponding inclined beam 4 are in the same plane. The inclined cables 7 are installed on the column 3, with one end connected to the column 3 and the other end connected to the lower frame 2. The inclined cables 7 generate a lifting force on the lower frame 2, thereby enhancing the stability of the lower frame 2 of the heavy-duty freight elevator frame 100.

[0032] In one embodiment, multiple stay cables 7 are provided on each column 3, and the multiple stay cables 7 are located on the same side of the column 3. In another embodiment, the number of stay cables 7 connected to each column 3 is an even number and is symmetrical with respect to the axis of the column 3. By symmetrically arranging the stay cables 7, the stress on the lower frame 2 is evenly distributed, ensuring the stability of the heavy-duty freight elevator frame 100 structure.

[0033] In the heavy-duty freight elevator frame 100 of this utility model, the lower frame 2 further includes multiple lower auxiliary beams 23. These lower auxiliary beams 23 are located on the side of the lower frame 2 away from the upper frame 1 and are evenly distributed in a second direction. The lower auxiliary beams 23 are parallel to the lower longitudinal beams 21. By providing lower auxiliary beams 23 on the lower frame 2, the rigidity of the lower frame 2 is enhanced, preventing deformation of the lower frame 2 when bearing heavy loads. Figure 1 As shown, in one embodiment, the stay cable 7 is connected to the lower sub-beam 23.

[0034] Please refer to this again. Figure 1 The lower frame 2 also includes multiple lower main beams 24, which are disposed on the side of the lower frame 2 away from the upper frame 1, and are parallel to the lower secondary beams 23. In one embodiment, the height of the lower main beam 24 is greater than the height of the lower secondary beam 23, and the width of the lower main beam 24 is greater than the width of the lower secondary beam 23. By providing the lower main beams 24, the rigidity of the lower frame 2 is further enhanced. In one embodiment, as shown... Figure 1 As shown, each lower main beam 24 is connected to two symmetrically arranged columns 3 at both ends.

[0035] With the height of the lower main beam 24 greater than the height of the lower secondary beam 23, and the width of the lower main beam 24 greater than the width of the lower secondary beam 23, multiple buffers (not shown) are provided along the length of each lower main beam 24 on the side away from the cargo plate 6. Because the height of the lower main beam 24 is greater than the height of the lower secondary beam 23, when the heavy-duty freight elevator frame 100 of this invention falls to the ground, the lower main beam 24 is the first to contact the ground. Due to the large load of the heavy-duty freight elevator frame 100, this can easily damage the lower main beam 24, and may also cause damage to the goods due to vibration. By setting buffers, the buffers play a cushioning role when the heavy-duty freight elevator frame 100 falls to the ground.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
