Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a steel structure hoistway for an elevator. Background Technology

[0002] The steel structure frame of an elevator refers to the steel structure support installed inside or outside the elevator shaft, and it is an important component of the elevator system.

[0003] A search revealed that patent CN202222979712.5 discloses a steel structure hoistway for an elevator. While this device features unit crossbars at both ends of the unit columns, with a reinforcing member fixedly connected to the unit column at the end furthest from the crossbar, and a groove at the end of the crossbar furthest from the column, and a lifting member fixedly connected to the crossbar on one side, allowing for convenient and quick assembly of the unit columns and crossbars into a single frame, thus improving installation efficiency, the device relies solely on sliding grooves and sliding parts for assembly. While convenient and quick, this connection method results in relatively low strength. Over time or under external impact, the connections may loosen or become damaged, affecting the overall stability and safety of the hoistway. Furthermore, due to insufficient connection strength, the hoistway may deform or collapse under external forces, posing a serious threat to elevator equipment and passengers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel structure hoistway for an elevator, solving the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A steel structure hoist of an elevator includes a steel frame, wherein the steel frame is provided with columns, transverse support beams, diagonal support beams and longitudinal support rods, the two ends of the columns are provided with connecting plates, and the connecting plates are provided with fixing holes, the steel frames are locked together by connectors passing through the fixing holes, and the bottom end of the steel frame is provided with a base plate;

[0007] Two steel frames are connected and fixed together by a connecting seat. The connecting seat has a through hole and a positioning block at the through hole. The positioning block is inserted into the fixing hole of the column to limit the installation of the connecting seat between the two steel frames. The outside of the connecting seat is equipped with a barrier.

[0008] The column has plug-in blocks at both ends, each plug-in block has a first plug-in tooth, and a first plug-in groove is provided between the first plug-in teeth. The transverse support beam and the longitudinal support rod have second plug-in teeth and second plug-in grooves at both ends. The transverse support beam and the longitudinal support rod are connected to the first plug-in tooth and the first plug-in groove of the plug-in block through the second plug-in tooth and the second plug-in groove, so that the transverse support beam, the longitudinal support rod and the column are connected in a limited position.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the connecting seat has a slot on one side of the enclosure, and there are two slots in total. The slots of the connecting seat are diagonally distributed on both sides of the connecting seat.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The diagonally distributed slot design allows the connecting plate to be more easily and symmetrically inserted into the connector from both sides. This design simplifies the assembly process, reduces assembly difficulty, and improves work efficiency. During disassembly, the diagonally distributed slots also make it easier to remove the connecting plate from the connector, facilitating maintenance and component replacement. Inserting the connecting plate through the diagonally distributed slots and applying pressure for fixation ensures a stronger and more stable connection between the connector and the column. This design helps to distribute stress and reduce the risk of structural failure due to stress concentration.

[0013] Furthermore, the connecting plates at both ends of the column are symmetrically inserted into the connecting seats from both sides through slots and are installed on the connecting seats by means of a retaining barrier.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] This design allows the connecting plates to be inserted symmetrically into the slots from both sides, making the assembly process more intuitive and simple. No complicated adjustments or alignment steps are required to quickly connect the columns to the connecting seats. The limiting effect of the enclosure further simplifies the installation process, ensuring the stability of the connecting plates in the correct position and reducing the possibility of installation errors. The connecting plates are inserted into and fixed to the connecting seats through the slots, forming a stable connection structure. This design helps to distribute stress, improving the overall structural stability and load-bearing capacity. The limiting effect of the enclosure further enhances the stability of the connection, preventing the connecting plates from shifting or loosening under stress, thereby ensuring the safety of the elevator steel structure hoistway.

[0016] Furthermore, the inclined support beam, transverse support beam, longitudinal support rod, and column are welded and fixed together.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] Welding provides strong connection strength, ensuring that components are tightly and securely linked together. This high-strength connection significantly improves the stability and load-bearing capacity of the overall structure, enabling it to withstand greater external forces and deformations. Welding allows components to be tightly connected, reducing gaps and redundant space at the joints. This helps optimize the space utilization of the overall structure, making it more compact and aesthetically pleasing.

[0019] Furthermore, the connection between the steel frame and the base plate is provided with supporting stiffeners.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] As a reinforcing component, the supporting stiffener effectively improves the strength and rigidity of the connection between the steel frame and the base plate. Through welding or bolting, the supporting stiffener can firmly connect the steel frame and the base plate together, forming a unified structure. The presence of the supporting stiffener can distribute stress at the connection point, preventing structural damage caused by stress concentration. It effectively transfers and disperses loads from the steel frame and base plate, improving the overall load-bearing capacity of the structure.

[0022] Furthermore, the inclined support beams and longitudinal support rods are symmetrically distributed on both sides of the steel frame.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The symmetrical distribution of the design ensures a more balanced stress distribution on the steel frame, preventing structural instability caused by uneven stress. The synergistic effect of the diagonal support beams and longitudinal support rods more effectively resists horizontal and vertical loads, improving the overall structural stability. The symmetrical distribution of the diagonal support beams and longitudinal support rods makes the stress distribution on the steel frame more rational. This design can more effectively disperse and transfer loads, reducing stress concentration in individual components, thereby improving the overall structural performance and durability. Due to their inclination angle, the diagonal support beams provide additional lateral force resistance. When the steel frame is subjected to lateral wind loads or seismic loads, the diagonal support beams can effectively absorb and disperse these loads, protecting the overall structure from damage.

[0025] This utility model provides a steel structure shaft for an elevator. It has the following beneficial effects:

[0026] The steel frame, composed of columns, transverse support beams, diagonal support beams, and longitudinal support rods, forms a stable framework structure. The diagonal support beams and longitudinal support rods are symmetrically distributed on both sides of the steel frame, enhancing the overall stability of the structure. All components are welded together and fixed, further improving the strength and stability of the structure.

[0027] The design of the connecting plates at both ends of the column allows the steel frames to be locked together through the fixing holes of the connectors, which facilitates quick assembly and disassembly and improves construction efficiency.

[0028] The design of the plug-in block, the first plug-in tooth, the first plug-in slot, the second plug-in tooth, and the second plug-in slot allows the transverse support beam, the longitudinal support rod, and the column to be easily connected and positioned via plug-in, further simplifying the assembly process.

[0029] The connector design allows for a secure connection between the two steel frames. The positioning block is inserted into the fixing hole of the column, limiting the connector's installation between the two steel frames and ensuring the accuracy and stability of the connection.

[0030] The enclosure design prevents the connecting plates at both ends of the column from detaching from the connector, further enhancing the reliability of the connection. The slot design allows the connecting plates at both ends of the column to be easily inserted symmetrically into the connector from both sides through the slot, and then fixed on the connector by the enclosure, simplifying the installation process.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0041] Example 1

[0042] An elevator steel structure hoist includes a steel frame 1. The steel frame 1 has columns 111, transverse support beams 103, diagonal support beams 102, and longitudinal support rods 104. The diagonal support beams 102 and longitudinal support rods 104 are symmetrically distributed on both sides of the steel frame 1. This symmetrical distribution ensures the balance of the steel frame 1 under stress, avoiding structural instability caused by uneven stress. The synergistic effect of the diagonal support beams 102 and longitudinal support rods 104 more effectively resists horizontal and vertical loads, improving the overall structural stability. The symmetrical distribution of the diagonal support beams 102 and longitudinal support rods 104 optimizes the stress distribution of the steel frame 1. This design more effectively disperses and transfers loads, reduces stress concentration in individual components, and improves the overall structural performance and durability. The diagonal support beams 102, due to their inclination angle, provide additional resistance to lateral forces. When the steel frame 1 is subjected to lateral wind loads or seismic loads, the diagonal support beam 102 can effectively absorb and disperse these loads, protecting the overall structure from damage. The diagonal support beam 102, the transverse support beam 103, the longitudinal support rod 104, and the column 111 are welded together and fixed. The welding and fixing technology provides strong connection strength, ensuring a tight and firm connection between the components. This high-strength connection method significantly improves the stability and load-bearing capacity of the overall structure, enabling it to withstand greater external forces and deformations. The welding and fixing technology also achieves a tight connection between components, reducing gaps and redundant space at the connection points, optimizing the space utilization of the overall structure, making it more compact and aesthetically pleasing. The two ends of the column 111 are provided with connecting plates, and the connecting plates are provided with fixing holes. The steel frames 1 are locked together by connecting parts 101 passing through the fixing holes. The bottom end of the steel frame 1 is provided with a base plate 105. The connection between the steel frame 1 and the base plate 105 is provided with a support stiffener. As a structural strengthening element, the support stiffener significantly improves the strength and rigidity of the connection between the steel frame 1 and the base plate 105. Through welding or bolting, the supporting stiffeners firmly connect the steel frame 1 and the base plate 105 into a single structure. The presence of the supporting stiffeners effectively disperses the stress at the connection points, preventing structural damage caused by stress concentration. It also effectively transfers and disperses the loads from the steel frame 1 and the base plate 105, improving the overall load-bearing capacity of the structure.

[0043] Example 2

[0044] To further ensure the splicing speed and accuracy of steel frame 1, for example, such as Figures 1 to 4 As shown, the invention further includes: two steel frames 1 connected and fixed together by a connecting seat 2. The connecting seat 2 has a through hole, and a positioning block 202 is provided at the through hole. The positioning block 202 is inserted into the fixing hole of the column 111, limiting the installation of the connecting seat 2 between the two steel frames 1. A retaining wall 203 is provided on the outer side of the connecting seat 2. A slot 201 is provided on one side of the retaining wall 203 on the connecting seat 2. There are two slots 201, and they are diagonally distributed on both sides of the connecting seat 2. The diagonal slot 201 design optimizes the assembly path of the connecting plate, allowing it to be more smoothly and symmetrically inserted into the connecting seat 2 from both sides. This design simplifies the assembly process, reduces technical difficulty, and improves work efficiency. During disassembly, the diagonal slot 201 also facilitates the quick removal of the connecting plate, providing convenience for component maintenance and replacement. The diagonal arrangement of the slots 201 and the pressure fixation of the connecting plates ensure the firmness and stability of the connection between the connecting seat 2 and the column 111, effectively dispersing stress and reducing the risk of structural failure caused by stress concentration. The connecting plates at both ends of the column 111 are symmetrically inserted into the connecting seat 2 from both sides through the slots 201 and are fixed on the connecting seat 2 by the retaining wall 203. This design realizes an intuitive assembly method of symmetrically inserting the connecting plates into the slots 201 from both sides, which can quickly complete the connection between the column 111 and the connecting seat 2 without complicated calibration or alignment steps. The limiting function of the retaining wall 203 further simplifies the installation process, ensures the stability of the connecting plates in the predetermined position, and reduces installation errors. The connecting plates are inserted into and fixed to the connecting seat 2 through the slots 201, forming a stable connection structure, effectively dispersing stress, and improving the stability and load-bearing capacity of the overall structure. The limiting effect of the retaining wall 203 further enhances the stability of the connection, prevents the connecting plates from shifting or loosening under stress, and ensures the safety of the elevator steel structure hoist.

[0045] Example 3

[0046] To ensure the connection strength between the components of steel frame 1, for example, such as Figures 1 to 4As shown, the present invention also includes: two ends of the column 111 are provided with plug-in blocks 106, the plug-in blocks 106 are provided with first plug-in teeth 107, and the first plug-in teeth 107 are provided with first plug-in grooves 108; the two ends of the transverse support beam 103 and the longitudinal support rod 104 are provided with second plug-in teeth 109 and second plug-in grooves 110; the transverse support beam 103 and the longitudinal support rod 104 are mutually plugged with the first plug-in teeth 107 and the first plug-in grooves 108 of the plug-in block 106 through the second plug-in teeth 109 and the second plug-in grooves 110, so that the transverse support beam 103, the longitudinal support rod 104 and the column 111 are limited and spliced. Through the mutual cooperation of the plug-in blocks 106, the plug-in teeth and the plug-in grooves, the rapid and accurate assembly between the transverse support beam 103, the longitudinal support rod 104 and the column 111 is realized. This plug-in connection method eliminates the need for complex connectors 101 or additional fasteners, greatly simplifying the assembly process and reducing assembly difficulty. The design of the plug-in block 106 and the plug teeth makes the connection between the various components tighter and more secure. Through interlocking, they can effectively resist external forces, preventing structural loosening or deformation, thereby improving the overall structural stability. This design enhances the load-bearing capacity of the structure by distributing stress. The cooperation between the plug-in block 106 and the plug teeth allows the load to be distributed more evenly throughout the structure, avoiding structural damage caused by stress concentration.

[0047] Working principle:

[0048] The column 111 has insertion blocks 106 at specific locations (such as both ends or the middle), and these insertion blocks 106 have first insertion teeth 107 and first insertion slots 108. The transverse support beam 103 and the longitudinal support rod 104 have second insertion teeth 109 and second insertion slots 110 at both ends, which match the first insertion teeth 107 and the first insertion slots 108. During assembly, the second insertion teeth 109 and the second insertion slots 110 of the transverse support beam 103 and the longitudinal support rod 104 are inserted into the first insertion teeth 107 and the first insertion slots 108 of the insertion blocks 106 of the column 111. This insertion method ensures a secure connection between the transverse support beam 103, the longitudinal support rod 104, and the column 111, and is further fixed by welding after insertion.

[0049] The column 111 has connecting plates at both ends, with fixing holes for connecting to the connecting seat 2. The connecting seat 2 has through holes with positioning blocks 202 at the through holes. The shape and size of the positioning blocks 202 match the fixing holes on the connecting plates of the column 111. During assembly, the connecting plates at both ends of the column 111 are symmetrically inserted from both sides through the slots 201 of the connecting seat 2 to ensure accurate alignment with the positioning blocks 202. This diagonally symmetrical insertion and fixing method helps ensure a stronger and more stable connection between the column 111 and the connecting seat 2. By applying pressure from both sides, the stress on the connecting plates can be evenly distributed, reducing the risk of structural failure due to stress concentration. Once the connecting plates are fully inserted and aligned with the positioning blocks 202, they are fixed within the connecting seat 2. At this point, the enclosure 203 (which may be one or more components, such as side plates or cover plates) is installed on the connecting seat 2 to prevent the connecting plates from coming out of the slots 201. The limiting function of the enclosure 203 ensures a firm connection between the column 111 and the connecting seat 2, thus forming a stable structural unit.
