Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a reinforcement structure for a heavy-duty standard section of an elevator. Background Technique

[0002] Elevators are widely applicable to the vertical lifting and transportation of personnel and materials, and are widely used in industrial or civil buildings, large bridges, and shafts. Standard sections are used for the installation of elevators. A standard section is a tower section with standard dimensions used to change the height of the tower of an elevator, etc. Usually, a standard section assembly of an elevator with high structural strength is used.

[0003] The prior art 202223356963.4 discloses a new type of construction elevator guide rail frame standard section, including four main limbs of the guide rail frame standard section. Three first transverse web members are fixedly connected between the two front main limbs of the guide rail frame standard section and between the two rear main limbs of the guide rail frame standard section. A connection mechanism is assembled between the multiple first transverse web members; double-row toothed racks are assembled on the front of the three first transverse web members on the front and on the back of the three first transverse web members on the back. Both sides of the double-row toothed rack are meshed with two driving gears, and the driving gears are connected to an external driving mechanism; however, for the reinforcement section, the position of the L-shaped transverse web member in the disclosed document belongs to the main stress point through calculation, so structural type strengthening treatment is required to avoid deformation during long-term use and thus pose certain potential safety hazards. Content of the Utility Model

[0004] The utility model aims to solve the above problems, thereby providing a reinforced standard section structure for an elevator that reduces potential safety hazards.

[0005] The technical solution adopted by the utility model to solve the above problems is:

[0006] A reinforced standard section structure for an elevator includes four columns. A number of layers of L-shaped first transverse web members are oppositely arranged between the two front columns and between the two rear columns. A first diagonal brace is arranged between the first transverse web member and the column. A second transverse web member is arranged between the ends of two first transverse web members in the same layer. The second transverse web member is in a trough shape and the opening faces inward. A toothed rack is longitudinally arranged on the outer side surfaces of the first transverse web members on the same side.

[0007] The utility model adopting the above technical solution, compared with the prior art, its prominent feature is:

[0008] Two of the four L-shaped transverse web members in the same layer are changed to trough shape, which has strong stability and tensile strength, prevents deformation during long-term use, and reduces potential safety hazards.

[0009] Preferably, a further technical solution of the present utility model is as follows:

[0010] Further, a second diagonal web member is arranged between the diagonals of adjacent second horizontal web members up and down, which can improve the stiffness of the lift and enhance the running stability, avoid the lift from shaking during operation, and at the same time reduce the influence brought by external factors such as wind.

[0011] Further, a support plate is arranged at a position in the opening of the second horizontal web member and adjacent to the end of the second diagonal web member. The second horizontal web member and the support plate form a frame structure, which is more conducive to the support force of the diagonal web member. The connection between the second horizontal web member and the second diagonal web member is further strengthened through the support plate to prevent the second diagonal web member from pressing the second horizontal web member and causing deformation.

[0012] Further, connection holes are relatively provided on the first horizontal web member and the rack, a connection bolt is movably penetrated through the connection holes together, a locking nut is sleeved on the connection bolt and located inside the first horizontal web member, and a square cushion block is arranged between the locking nut and the first horizontal web member on the connection bolt. Description of the Drawings

[0013] Figure 1 It is a schematic three-dimensional structure diagram of an embodiment of the present utility model;

[0014] The labels in the figure are: column 1, first horizontal web member 2, second horizontal web member 3, first diagonal web member 4, second diagonal web member 5, support plate 6, rack 7, connection bolt 8, square cushion block 9. Detailed Embodiment

[0015] The present utility model will be further described below in conjunction with embodiments. The purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.

[0016] A reinforced standard section structure of a lift includes four columns 1. A number of layers of L-shaped first horizontal web members 2 are oppositely arranged between the front two columns 1 and between the rear two columns 1. The first horizontal web members 2 are made of angle steel. A first diagonal support 4 is arranged between the first horizontal web members 2 and the columns 1. A second horizontal web member 3 is arranged between the ends of two first horizontal web members 1 of the same layer. The second horizontal web member 3 is in a trough shape and the opening faces inward. A rack 7 is longitudinally arranged on the outer side surfaces of the first horizontal web members 1 on the same side. The second horizontal web member 3 is made of channel steel. Compared with steel pipes, using channel steel as the second horizontal web member 3 not only meets the strength requirements of the reinforcement section but also can better save costs.

[0017] Further, a second diagonal web member 5 is arranged between the diagonals of adjacent second horizontal web members 3 up and down, which can improve the stiffness of the lift and enhance the running stability, avoid the lift from shaking during operation, and at the same time reduce the influence brought by external factors such as wind.

[0018] Furthermore, a support plate 6 is provided at a position in the opening of the second horizontal web member 3 and adjacent to the end of the second diagonal web member 5. The second horizontal web member 3 and the support plate 6 form a frame structure, which is more conducive to the force-bearing of the diagonal web member. The connection between the second horizontal web member 3 and the second diagonal web member 5 is further strengthened through the support plate 6 to prevent the second diagonal web member 5 from squeezing the second horizontal web member 3 and causing deformation.

[0019] Furthermore, connection holes are oppositely formed on the first horizontal web member 3 and the rack 7, and a connection bolt 8 is movably penetrated through the connection holes together. A locking nut is sleeved on the connection bolt 8 and located inside the first horizontal web member 3. A square cushion block 9 is arranged between the locking nut and the first horizontal web member 3 on the connection bolt 8. Traditional cushion blocks are circular, but on the reinforcing section, the circular cushion block has a small force-bearing area and is likely to cause deformation of the first horizontal web member 3. The square cushion block 9 is adopted to increase the force-bearing area.

[0020] Two of the four L-shaped horizontal web members on the same layer are changed to channel-shaped, which has strong stability and tensile strength, prevents deformation during long-term use, and reduces potential safety hazards.

[0021] The above are only the preferred and feasible embodiments of the present utility model, and do not limit the scope of rights of the present utility model accordingly. Any equivalent changes made by using the content of the specification and drawings of the present utility model are included within the scope of rights of the present utility model.
