Description

Technical Field

[0001] This utility model belongs to the technical field of elevator equipment, and in particular relates to an elevator car frame and an elevator. Background Technology

[0002] The elevator car frame is a crucial component of an elevator, used to support the elevator car. Therefore, the rationality of the elevator car frame structure design plays a vital role in the elevator's operational stability, safety, and comfort.

[0003] In related technologies, a weighing mechanism is arranged on the bracket of the elevator car frame to support the car. This weighing mechanism detects the downward force exerted by the car on the bracket, thus achieving the purpose of load detection. Simultaneously, a shock-absorbing mechanism is arranged between the car and the elevator car frame to buffer and reduce vibration, improving the passenger experience. Currently, the elevator car frame uses C-channel steel to support the weighing mechanism. However, due to the structural characteristics of C-channel steel, the assembly of both the bracket and the weighing mechanism requires separate space in the height direction of the elevator car frame. Similarly, the assembly structure of the shock-absorbing pads also requires additional space in the height direction between the car and the elevator car frame. This significantly increases the overall height of the elevator car frame, thus affecting the utilization rate of the shaft. Utility Model Content

[0004] In view of this, it is necessary to provide an elevator car frame and elevator that can improve the utilization rate of the shaft.

[0005] An elevator car frame, the elevator car frame comprising:

[0006] The upper beam assembly is connected to a straight beam at the bottom;

[0007] The lower beam is disposed on the straight beam at one end away from the upper beam assembly and is connected to the straight beam;

[0008] A bracket frame for supporting the car includes multiple crossbeams and a support beam. The multiple crossbeams are arranged sequentially and spaced apart along the length of the lower beam and are respectively connected to the lower beam. The support beam includes a first plate and a second plate. The first plate is attached to one end of the multiple crossbeams and is respectively connected to the multiple crossbeams. The second plate is connected to the side of the first plate opposite to the crossbeams and is used to support the weighing switch and / or the shock absorption mechanism.

[0009] It is understandable that using the second plate on the support beam to support the weighing switch, and utilizing the connection between the second plate and the first plate, allows the assembly space of the weighing switch and / or damping mechanism in the elevator car height direction to be at least partially integrated into the assembly space of the first plate. This saves the installation space required for assembling the weighing switch and / or damping mechanism on the second plate, thus improving the utilization rate of the shaft. On the other hand, it also simplifies the structure of the support beam, saving the amount of material required for its manufacture.

[0010] In one embodiment, the second plate is vertically disposed at the bottom end of the first plate and is integrally connected to the first plate.

[0011] Understandably, by vertically connecting the second plate to the bottom of the first plate, the elevator car frame can make full use of the mounting space of the support beam in the height direction of the elevator car frame to accommodate the weighing switch, thereby further improving the utilization rate of the shaft.

[0012] In one embodiment, two adjacent crossbeams of the plurality of crossbeams are combined to form a crossbeam group, and the two crossbeams in the crossbeam group are connected by a bending member;

[0013] The bent component is attached to and connected to the first plate.

[0014] It is understandable that using bending components to connect two adjacent crossbeams to the first plate can improve the stability of the support beam when it is assembled on multiple crossbeams, thus improving the overall structural stability of the bracket frame.

[0015] In one embodiment, the bending member includes a connecting main board, a first bending plate, and a second bending plate, wherein the first bending plate and the second bending plate are disposed at both ends of the connecting main board and are respectively connected to the connecting main board;

[0016] The connecting main board is connected to the first plate body by a thread, the first bending plate is connected to one of the crossbeams in the crossbeam group by a thread, and the second bending plate is connected to the other crossbeam in the crossbeam group by a thread.

[0017] It is understandable that the above structural design facilitates the assembly and connection between the bent component and the first plate on the support beam and the two crossbeams in the crossbeam group.

[0018] In one embodiment, the number of beam groups is configured to be at least three groups, and the spacing between any two adjacent beam groups in the at least three groups is equal.

[0019] It is understandable that arranging at least three sets of crossbeams evenly on the lower beam can improve the overall structural strength and stability of the bracket frame. On the other hand, it can also ensure that the bracket frame can evenly distribute the load on the car and ensure the balance of the elevator car frame when carrying the car, thereby improving the safety and stability of the elevator operation using this elevator car frame.

[0020] In one embodiment, the crossbeam is welded to the first plate.

[0021] It is understandable that welding the crossbeam to the first plate of the supporting beam can improve the stability of the connection between the crossbeam and the first plate.

[0022] In one embodiment, the support beam further includes an end plate disposed at the end positions of the first plate and the second plate;

[0023] The end plate is connected to the straight beam located adjacent to the end plate by a diagonal tie rod.

[0024] Understandably, by using diagonal bracing to connect the support beam and the straight beam, a stable triangular structure is formed between the bracket frame and the straight beam. This improves the overall stability of the bracket frame and prevents excessive local stress on the elevator car structure, thus ensuring the safety and reliability of elevators using this type of frame during operation.

[0025] In one embodiment, the elevator car frame further includes a rope end plate, which is mounted on the upper beam assembly for connecting the traction rope.

[0026] Understandably, the upper beam assembly uses a rope end plate to connect the traction rope, making the elevator car frame compatible with a 1:1 rope winding ratio. This ensures that when the elevator car frame is used in elevator operation, the tension of the traction rope changes evenly, thus reducing the swaying and vibration of the car.

[0027] In one embodiment, the elevator car frame further includes a compensating rope end assembly, which is threadedly connected to the lower beam.

[0028] Understandably, the compensating rope head assembly is connected to the lower beam by threads, which facilitates the assembly and connection of the compensating rope head assembly on the lower beam.

[0029] In one embodiment, the compensating rope head assembly is centrally located on the lower beam along the length and / or width of the lower beam.

[0030] In addition, this application also provides an elevator, including the elevator car frame described above.

[0031] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0032] The elevator car frame and elevator claimed in this application use a second plate on a support beam to support a weighing switch. By utilizing the connection method between the second plate and the first plate, the assembly space of the weighing switch and / or shock absorption mechanism in the height direction of the elevator car frame can be at least partially integrated into the assembly space of the first plate. This saves the installation space required for assembling the weighing switch and / or shock absorption mechanism on the second plate, thereby improving the utilization rate of the shaft. On the other hand, it also simplifies the structure of the support beam, thereby saving the amount of material required to manufacture the support beam. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] like Figures 1 to 4 As shown, the elevator car frame 100 provided in this application includes an upper beam assembly 10, a lower beam 20, and a bracket frame 30. The upper beam assembly 10 is connected downward to a straight beam 11. The lower beam 20 is disposed on the straight beam 11 at one end away from the upper beam assembly 10 and is connected to the straight beam 11. The bracket frame 30 is used to carry the car (not shown). The bracket frame 30 includes multiple crossbeams 31 and a support beam 32. The multiple crossbeams 31 are arranged sequentially and spaced along the length direction of the lower beam 20 and are respectively connected to the lower beam 20. The support beam 32 includes a first plate 321 and a second plate 322. The first plate 321 is attached to one end of the multiple crossbeams 31 and is respectively connected to the multiple crossbeams 31. The second plate 322 is connected to the side of the first plate 321 away from the crossbeams 31 and is used to carry a weighing switch (not shown) and / or a shock absorption mechanism (not shown). Here, each of the two ends of the multiple crossbeams 31 is connected to a support beam 32. It should be noted that the aforementioned weighing switch is used to detect the force exerted by the car pressing down on the bracket frame 30, and the weighing switch transmits force to the car through a shock-absorbing mechanism. The shock-absorbing mechanism provides cushioning and vibration reduction for the car.

[0044] As can be seen from the above, the elevator car frame 100 of this application supports the weighing switch through the second plate 322 on the support beam 32. By utilizing the connection between the second plate 322 and the first plate 321, the weighing switch can be housed in the cavity formed by the first plate 321 and the second plate 322. This allows the assembly space of the weighing switch and / or the shock absorption mechanism in the height direction of the elevator car frame 100 to be at least partially integrated into the assembly space of the first plate 321. On the one hand, this can save the installation space required for assembling the weighing switch and / or the shock absorption mechanism on the second plate 322, thereby improving the utilization rate of the shaft. On the other hand, it can also simplify the structure of the support beam 32, thereby saving the amount of material required for manufacturing the support beam 32.

[0045] It should be noted that, since the support beam 32 of this application is connected by a first plate 321 and a second plate 322 along the length of the lower beam 20, that is, the support beam 32 of this application consists of two plates along its length. In contrast, existing C-channel steel consists of three plates along its length. Clearly, the structure of the support beam 32 of this application saves one main plate compared to existing C-channel steel, thereby reducing the amount of material required to manufacture the support beam 32.

[0046] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the upper beam assembly 10 serves as the top support component of the elevator car frame 100 structure. Specifically, it can be made of channel steel, which has good load-bearing capacity and resistance to deformation.

[0047] like Figure 1 , Figure 4 As shown, in one embodiment, two straight beams 11 are configured, which are vertically connected to the two ends of the upper beam assembly 10 and the lower beam 20 to enhance the lateral stability of the elevator car frame 100 structure. Here, the straight beams 11 are made of bent parts, which reduces their own weight while ensuring sufficient strength and rigidity; and the length direction of the lower beam 20 is consistent with the length direction of the upper beam assembly 10.

[0048] In one embodiment, the crossbeam 31 is connected to the first plate 321 by welding. This welding connection improves the stability of the connection between the crossbeam 31 and the first plate 321. Here, each crossbeam 31 has a support beam 32 welded to each of its two ends, thus meeting the requirements of the bracket frame 30 for supporting the weight of the car. Multiple crossbeams 31 are then welded to the lower beam 20.

[0049] like Figure 2 , Figure 4As shown, in one embodiment, two adjacent crossbeams 31 of the multiple crossbeams 31 are combined to form a crossbeam group 310. The two crossbeams 31 in the crossbeam group 310 are connected by a bending member 311. The bending member 311 is attached to and connected to the first plate 321. That is, while connecting two adjacent crossbeams 31, the bending member 311 also connects to the first plate 321 on the support beam 32. This strengthens the connection between the crossbeam 31 and the first plate 321 and improves the stability of the support beam 32 when assembled on the multiple crossbeams 31, thus enhancing the overall structural stability of the bracket frame 30. Here, bending members 311 are respectively arranged at both ends of the crossbeam group 310, and the connection between the two crossbeams 31 in the crossbeam group 310 is fixed by two bending members 311.

[0050] like Figure 1 , Figure 4 As shown, in this embodiment, the number of crossbeam groups 310 is configured to be at least three groups, and the spacing between any two adjacent crossbeam groups 310 is equal. This improves the overall structural strength and stability of the bracket frame 30, and also allows the bracket frame 30 to evenly distribute the load on the car, ensuring the balance of the elevator car frame 100 when carrying the car, thereby improving the safety and stability of the elevator using this elevator car frame 100. Here, the number of crossbeam groups 310 is configured to be three. It is understood that in other embodiments, the number of crossbeam groups 310 may also be configured to be four, five, or even more groups, which will not be elaborated here.

[0051] like Figure 2 , Figure 4 As shown, in one embodiment, the bending member 311 includes a connecting main board 3111, a first bending plate 3112, and a second bending plate 3113. The first bending plate 3112 and the second bending plate 3113 are disposed at both ends of the connecting main board 3111 and are respectively connected to the connecting main board 3111. Specifically, the connecting main board 3111, the first bending plate 3112, and the second bending plate 3113 can be connected into an integral structure.

[0052] In this embodiment, the connecting main plate 3111 is threaded to the first plate 321, the first bent plate 3112 is threaded to one of the crossbeams 31 in the crossbeam assembly 310, and the second bent plate 3113 is threaded to the other crossbeam 31 in the crossbeam assembly 310. Specifically, bolts can be used to achieve the assembly connection between the connecting main plate 3111 and the first plate 321, and between the first bent plate 3112 and the second bent plate 3113 and the two crossbeams 31 in the crossbeam assembly 310. This facilitates the assembly connection between the bent plate 311 and the first plate 321 on the support beam 32, and between the two crossbeams 31 in the crossbeam assembly 310.

[0053] like Figure 3 , Figure 4 As shown, in one embodiment, the second plate 322 is vertically disposed at the bottom end of the first plate 321 and is integrally connected to the first plate 321. This allows the support beam 32 to fully utilize the mounting space of the first plate 321 in the height direction of the elevator car frame 100 to accommodate the weighing switch. This further improves the utilization rate of the hoistway. Here, the first plate 321 and the second plate 322 can be formed from a single flat plate by bending. It is understood that in other embodiments, the second plate 322 can also be disposed independently relative to the first plate 321, and the connection between the second plate 322 and the first plate 321 can be achieved by welding; furthermore, the second plate 322 can also be disposed at different positions of the first plate 321 in the height direction of the elevator car frame 100, which will not be elaborated upon here.

[0054] like Figure 4 , Figure 5 As shown, in one embodiment, the elevator car frame 100 further includes a rope end plate 40, which is mounted on the upper beam assembly 10 and used to connect the traction rope (not shown). That is, the elevator car frame 100 is adapted to a 1:1 rope ratio, ensuring that the tension of the traction rope changes evenly when the elevator car frame 100 is used in an elevator, thus reducing car swaying and vibration. It should be noted that since the elevator car frame 100 of this application uses a rope end plate 40 to connect the traction rope, it is clear to those skilled in the art that the rope ratio of the elevator car frame 100 used in an elevator is 1:1. The elevator car frame 100 of this application is suitable for high-speed elevators.

[0055] like Figure 3 , Figure 4As shown, in one embodiment, the support beam 32 further includes an end plate 323, which is disposed at the end of the first plate 321 and the second plate 322, and can be integrated with the first plate 321 and the second plate 322. The end plate 323 is connected to the straight beam 11 adjacent to the end plate 323 by a diagonal tie rod 50, so that the bracket frame 30 and the straight beam 11 form a stable triangular structure. This improves the overall stability of the bracket frame 30, ensuring the safety and reliability of the elevator using the elevator car frame 100 during operation. Here, the diagonal tie rod 50 can be connected to the corresponding support beam 32 and straight beam 11 using high-strength bolts. It should be noted that the main function of the diagonal tie rod 50 is to optimize the mechanical properties of the elevator car frame 100 structure, enabling the elevator car frame 100 to effectively distribute stress during elevator operation, preventing excessive local stress and deformation or damage to the elevator car frame 100 structure.

[0056] It should be noted that the bracket frame 30 of this application needs to undergo strict dimensional inspection and quality testing before installation to ensure that the load-bearing performance of the bracket frame 30 meets the design requirements. Furthermore, when installing the bracket frame 30 on the lower beam 20, the multiple crossbeams 31 and support beams 32 of the bracket frame 30 can be laid flat at predetermined positions on the lower beam 20, and then the diagonal tie rods 50 can be assembled and connected to the corresponding straight beams 11 and the upper end plates 323 of the support beams 32 using high-strength bolts.

[0057] like Figure 1 As shown, in one embodiment, the elevator car frame 100 further includes a compensating rope head assembly 60, which is threadedly connected to the lower beam 20. This facilitates the assembly and connection of the compensating rope head assembly 60 to the lower beam 20. Specifically, the compensating rope head assembly 60 can be fixed to the lower beam 20 with bolts (not shown).

[0058] Furthermore, in this embodiment, the compensation rope head assembly 60 is centrally arranged on the lower beam 20 along the length and / or width direction of the lower beam 20.

[0059] In addition, this application also provides an elevator, including the elevator car frame 100 described above.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
