Description

Technical Field

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

[0002] The car bottom platform is an important component of the elevator car, and the rationality of its structure and the quality of its performance have a significant impact on the overall operating quality of the elevator.

[0003] The weighing switch is located below the main body of the car platform and is used to detect the downward force of the car, thus measuring the car's load. Currently, existing car platforms typically incorporate multiple vibration damping pads along the force transmission path between the platform body and the weighing switch. These pads are directly mounted to multiple reinforcing ribs in the platform body, which are connected to the car floor plate to reinforce its structure. However, this design results in uneven stress distribution on the car floor plate, which is subjected to the reaction forces of the reinforcing ribs. This imbalance fails to balance the vibrations generated during elevator car operation and reduces the accuracy of the subsequent weighing by the weighing switch. Utility Model Content

[0004] Therefore, it is necessary to provide a car bottom platform and elevator that are subjected to uniform force and can balance vibration.

[0005] A car floor platform, the car floor platform comprising:

[0006] Platform entity;

[0007] A connecting bracket is disposed below the platform body and connected to the platform body;

[0008] Multiple shock-absorbing pads are arranged sequentially and at intervals along the length of the connecting bracket on the side of the connecting bracket facing away from the platform body, and are respectively connected to the connecting bracket;

[0009] The connecting plate is attached upwards to the plurality of shock-absorbing pads and is connected to the plurality of shock-absorbing pads respectively;

[0010] A weighing switch is located below the connecting plate and connected to the connecting plate.

[0011] It is understandable that connecting brackets are used to transmit the force between the platform body and multiple shock-absorbing pads, and connecting plates are used to connect multiple shock-absorbing pads and weighing switches together. This can, on the one hand, make the platform body bear the force evenly, and play a role in balancing the overall vibration of the platform body during the operation of the elevator car with the car bottom platform; on the other hand, it can also prevent the relative displacement of the shock-absorbing pads and weighing switches, thereby improving the weighing accuracy.

[0012] In one embodiment, the connecting bracket includes a connecting motherboard, a first bending plate, and a second bending plate. The first bending plate and the second bending plate are disposed on both sides of the connecting motherboard and are respectively connected to the connecting motherboard to form an integral structure.

[0013] The first bending plate and the second bending plate respectively abut against the platform body and are connected to the platform body; the shock-absorbing pad abuts against the connecting motherboard and is connected to the connecting motherboard.

[0014] In one embodiment, the shock-absorbing pad includes a shock-absorbing pad body and a first connector, the first connector extending outward relative to the shock-absorbing pad body and connected to the shock-absorbing pad body;

[0015] One end of the shock-absorbing pad body is attached to the connecting motherboard, and the first connector is connected to the connecting motherboard by means of threads.

[0016] It is understandable that the shock-absorbing pad is assembled and connected to the connecting bracket by screwing the first connector in the shock-absorbing pad to the connecting motherboard, which makes it easier to assemble and fix the shock-absorbing pad to the connecting bracket.

[0017] In one embodiment, the first connector is partially embedded in the damping pad body and connected to the damping pad body.

[0018] In one embodiment, the shock-absorbing pad has mounting holes;

[0019] The car floor platform further includes a second connector, which is correspondingly disposed with the shock-absorbing pad having the mounting hole. The second connector passes through the connecting plate and is inserted into the corresponding mounting hole.

[0020] Understandably, the connecting plate is pressed and fixed onto the shock-absorbing pad using the second connector, which makes it easier to fix the connecting plate onto the shock-absorbing pad.

[0021] In one embodiment, the number of weighing switches is configured to be multiple, and the multiple weighing switches are arranged sequentially at intervals along the length direction of the connecting bracket.

[0022] In one embodiment, the weighing switch is offset relative to the shock-absorbing pad along the length of the connecting bracket.

[0023] It is understandable that the weighing switch and the shock-absorbing pad are staggered to avoid positional interference when they are assembled on the connecting plate.

[0024] In one embodiment, the connecting plate is configured as a bent part;

[0025] The shock-absorbing pad is installed on the first end face of the connecting plate facing the connecting bracket, and the weighing switch is installed on the second end face of the connecting plate away from the connecting bracket.

[0026] Understandably, by utilizing the structural characteristics of the bent component, the overall structural strength of the connecting plate can be improved, preventing the connecting plate from bending under the action of the shock-absorbing pad and the weighing switch.

[0027] In one embodiment, the platform body includes a platform frame, a car floor plate, and multiple reinforcing ribs. The car floor plate is attached to and connected to the platform frame. The multiple reinforcing ribs are disposed inside the platform frame, and are arranged sequentially and at intervals along the length direction of the connecting bracket on a wall of the car floor plate facing the platform frame, and are respectively connected to the car floor plate.

[0028] The connecting bracket is connected to the platform frame.

[0029] In one embodiment, the car floor platform further includes a lower sealing plate, which is attached to one end face of the plurality of reinforcing ribs away from the car floor plate and is connected to the plurality of reinforcing ribs respectively.

[0030] Understandably, the structure of the bottom plate allows for better sealing of the car bottom platform, which reduces wind resistance and noise levels in elevator cars using this platform during operation.

[0031] In one embodiment, the platform body includes a platform frame and a car floor, the car floor being attached to and connected to the platform frame;

[0032] The platform frame includes two side rails, which are arranged opposite to each other. The portion of the car floor plate extending from the side rail along its length is bent downward in the vertical direction to form a bent plate portion, thereby constituting the front and rear rail structure of the platform frame.

[0033] In addition, this application also provides an elevator, including the car bottom platform described above.

[0034] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0035] The car bottom platform and elevator for which this application seeks protection use a connecting bracket to transmit the force between the platform body and multiple shock-absorbing pads, and a connecting plate to connect the multiple shock-absorbing pads and the weighing switch together. This can, on the one hand, make the platform body evenly stressed, and play a role in balancing the overall vibration of the platform body during the operation of the elevator car with the car bottom platform; on the other hand, it can also prevent the relative displacement of the shock-absorbing pads and the weighing switch, thereby improving the weighing accuracy.

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.

[0043] 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.

[0044] like Figures 1 to 3 As shown, the car floor platform 100 provided in this application includes a platform body 10, a connecting bracket 20, multiple shock-absorbing pads 30, a connecting plate 40, and a weighing switch 50. The connecting bracket 20 is located below the platform body 10 and connected to it. The multiple shock-absorbing pads 30 are arranged sequentially and at intervals along the length X of the connecting bracket 20 on a side 211 of the connecting bracket 20 facing away from the platform body 10, and are respectively connected to the connecting bracket 20. The connecting plate 40 is attached upward to the multiple shock-absorbing pads 30 and is respectively connected to the multiple shock-absorbing pads 30. The weighing switch 50 is located below the connecting plate 40 and connected to it. Here, the connecting bracket 20, the multiple shock-absorbing pads 30, the connecting plate 40, and the weighing switch 50 are combined to form a buffer weighing mechanism for weighing and damping the platform body 10. It should be noted that the number of buffer weighing mechanisms in the car bottom platform 100 of this application, as described above, is multiple, and the multiple buffer weighing mechanisms are symmetrically arranged below the platform body 10. It is understood that in other embodiments, the number of buffer weighing mechanisms may be two, three, four, or even more, which will not be elaborated here.

[0045] As can be seen from the above, the car bottom platform 100 of this application uses a connecting bracket 20 to realize the transmission of force between the platform body 10 and multiple shock-absorbing pads 30, and uses a connecting plate 40 to connect the multiple shock-absorbing pads 30 and the weighing switch 50 together. This can make the platform body 10 bear force evenly, and play a role in balancing the overall vibration of the platform body 10 during the operation of the elevator car with the car bottom platform 100; on the other hand, it can also prevent the relative displacement of the shock-absorbing pads 30 and the weighing switch 50, thereby improving the weighing accuracy.

[0046] It should be noted that since the multiple shock-absorbing pads 30 of this application are connected to the platform body 10 through the connecting bracket 20, when the buffer weighing mechanism weighs the platform body 10, the downward pressure of the platform body 10 can be distributed to the multiple shock-absorbing pads 30 through the connecting bracket 20. During this process, the platform body 10 and the connecting bracket 20 are in surface contact, which makes the platform body 10 bear the force evenly.

[0047] like Figure 1 , Figure 2 As shown, in one embodiment, the platform body 10 includes a platform frame 11, a car floor 12, and multiple reinforcing ribs 13. The car floor 12 is attached to and connected to the platform frame 11. The multiple reinforcing ribs 13 are disposed inside the platform frame 11, and are arranged at intervals along the length X of the connecting bracket 20 on a wall 121 of the car floor 12 facing the platform frame 11, and are respectively connected to the car floor 12. Here, the reinforcing ribs 13 are welded to the car floor 12 to enhance the structural strength of the car floor 12 to meet the usage requirements of carrying the car. It should be noted that the specific number and arrangement of the reinforcing ribs 13 in this embodiment can be reasonably set according to the size and load requirements of the car floor platform 100 to ensure the best structural reinforcement effect on the car floor 12.

[0048] like Figure 1 As shown, in this embodiment, the platform frame 11 includes two side rails 111, which are arranged opposite to each other. The portion of the car floor plate 12 extending from the side rails 111 along their length is bent downwards in the vertical direction to form a bent plate portion 120, thus constituting the front and rear rail structure of the platform frame 11. Here, the connecting bracket 20 is welded to the two side rails 111. Specifically, the connecting bracket 20 is arranged perpendicular to the side rails 111. It can be understood that in other embodiments, in addition to being connected to the two side rails 111, the connecting bracket 20 may abut against multiple reinforcing ribs 13, or a gap may be formed between the connecting bracket 20 and the reinforcing ribs 13; or the connecting bracket 20 may be directly welded and fixed to the multiple reinforcing ribs 13, without being connected to the two side rails 111. This will not be elaborated here.

[0049] like Figure 1 , Figure 2 As shown, in this embodiment, a foot protection plate assembly 14 is installed on one of the bent plate portions 120 of the car floor 12.

[0050] like Figure 3As shown, in one embodiment, the connecting bracket 20 includes a connecting main board 21, a first bending plate 22, and a second bending plate 23. The first bending plate 22 and the second bending plate 23 are disposed on both sides of the connecting main board 21 and are respectively connected to the connecting main board 21 as an integral structure. The first bending plate 22 and the second bending plate 23 abut against the platform body 10 and are connected to the platform body 10. The shock-absorbing pad 30 abuts against the connecting main board 21 and is connected to the connecting main board 21. Here, the first bending plate 22 and the second bending plate 23 are arranged perpendicular to the connecting main board 21; that is, the cross-section of the connecting bracket 20 is U-shaped, which can be manufactured by bending and forming, thereby improving the overall structural strength of the connecting bracket 20.

[0051] like Figure 2 , Figure 3 As shown, in this embodiment, the first bending plate 22 and the second bending plate 23 of the connecting bracket 20 abut against the two side rails 111 of the platform body 10 and are welded and fixed to the two side rails 111 respectively.

[0052] like Figure 3 As shown, in one embodiment, the shock-absorbing pad 30 includes a shock-absorbing pad body 31 and a first connecting member 32. The first connecting member 32 extends outward relative to the shock-absorbing pad body 31 and is connected to the shock-absorbing pad body 31. One end of the shock-absorbing pad body 31 is attached to the connecting main board 21, and the first connecting member 32 is connected to the connecting main board 21. This facilitates the assembly and fixation of the shock-absorbing pad 30 onto the connecting bracket 20. Here, the first connecting member 32 is connected to the connecting main board 21 by a thread, specifically, the first connecting member 32 can be configured as a screw, bolt, etc. It is understood that in other embodiments, the first connecting member 32 can also pass through the connecting main board 21 and be locked with a pin, or the first connecting member 32 can be connected and fixed to the connecting main board 21 by welding, snap-fit, etc., which will not be elaborated here.

[0053] like Figure 3 As shown, in this embodiment, the first connector 32 is partially embedded in the damping pad body 31 and connected to the damping pad body 31. Specifically, the damping pad body 31 and the first connector 32 can be integrally formed. It should be noted that the damping pad body 31 can be made of a material with good damping performance, so that the damping pad 30 can effectively absorb the vibration during the operation of the elevator car.

[0054] It is understood that in this embodiment, all shock-absorbing pads 30 in each buffer weighing mechanism of the car bottom platform 100 can be connected to the main board 21 in the manner described above. Of course, in other embodiments, some shock-absorbing pads 30 in each buffer weighing mechanism can be connected to the main board 21 using the first connector 32 described above, and the remaining shock-absorbing pads 30 can be connected to the main board 21 by adhesive bonding. This will not be elaborated here.

[0055] like Figure 1 As shown, in one embodiment, the shock-absorbing pad 30 has a mounting hole 311; the car bottom platform 100 also includes a second connecting member (not shown), which is correspondingly disposed with the shock-absorbing pad 30 having the mounting hole 311. The second connecting member passes through the connecting plate 40 and is inserted into the corresponding mounting hole 311. Here, the second connecting member is screwed into the mounting hole 311, thereby realizing the assembly connection between the shock-absorbing pad 30 and the connecting plate 40, which facilitates fixing the connecting plate 40 to the shock-absorbing pad 30. Specifically, the second connecting member can be a bolt, screw, etc. It is understood that in other embodiments, the shock-absorbing pad 30 and the connecting plate 40 can also be connected by bonding, welding, snap-fitting, etc., which will not be elaborated here.

[0056] It should be noted that in this embodiment, all shock-absorbing pads 30 and connecting plates 40 in each buffer weighing mechanism of the car bottom platform 100 can be connected in the manner described above. Of course, in other embodiments, some shock-absorbing pads 30 and connecting plates 40 in each buffer weighing mechanism can be connected in the manner described above using threads, and the remaining shock-absorbing pads 30 and connecting plates 40 can also be connected in the manner of adhesive bonding, which will not be elaborated here.

[0057] like Figure 3 As shown, in one embodiment, the connecting plate 40 is configured as a bent component, specifically formed by bending a flat plate. This improves the overall structural strength of the connecting plate 40 and prevents it from bending under the action of the shock-absorbing pad 30 and the weighing switch 50. Here, the shock-absorbing pad 30 is installed on the first end face 41 of the connecting plate 40 facing the connecting bracket 20, and the weighing switch 50 is installed on the second end face 42 of the connecting plate 40 facing away from the connecting bracket 20.

[0058] like Figure 1As shown, in one embodiment, the number of weighing switches 50 is configured to be multiple, and the multiple weighing switches 50 are arranged sequentially at intervals along the length direction X of the connecting bracket 20. Here, the number of weighing switches 50 in each buffer weighing mechanism is configured to be multiple, specifically arranged symmetrically; in one embodiment, the number of weighing switches 50 is configured to be three, one at each of the two ends of the connecting plate 40 and one in the middle of the connecting plate 40. It can be understood that in other embodiments, the number of weighing switches 50 in each buffer weighing mechanism can also be configured to be two, four, or even more. It should be noted that the weighing switches 50 and the connecting plate 40 can also be connected and fixed by bolts.

[0059] like Figure 1 As shown, in this embodiment, along the length direction X of the connecting bracket 20, the weighing switch 50 is staggered relative to the shock-absorbing pad 30, so that the weighing switch 50 and the shock-absorbing pad 30 are misaligned on the connecting bracket 20. This can avoid positional interference when the weighing switch 50 and the shock-absorbing pad 30 are assembled on the connecting plate 40.

[0060] like Figure 1 As shown, in one embodiment, the car bottom platform 100 further includes a lower sealing plate 60. The lower sealing plate 60 abuts against the end face 131 of the multiple reinforcing ribs 13 facing away from the car bottom plate 12 and is connected to the multiple reinforcing ribs 13 respectively. That is to say, the car bottom platform 100 of this embodiment can cover the car bottom plate 12 with the lower sealing plate 60, which can make the car bottom platform 100 have better sealing performance, thereby reducing the wind resistance and noise generated by the elevator car using the car bottom platform 100 during operation. Here, the aforementioned lower sealing plate 60 is provided between the two connecting brackets 20, between one connecting bracket 20 and the adjacent bent plate portion 120, and between the other connecting bracket 20 and the adjacent bent plate portion 120. Specifically, the lower sealing plate 60 can be bolted to the multiple reinforcing ribs 13.

[0061] In summary, during the fabrication of the car floor platform 100 of this application, the car floor plate 12 is abutted against two oppositely arranged side rails 111. Next, multiple reinforcing ribs 13 are sequentially welded to the car floor plate 12 according to design requirements. Then, connecting brackets 20 are welded to the two side rails 111, and multiple shock-absorbing pads 30 are assembled and fixed to the connecting brackets 20. Then, connecting plates 40 are used to connect the multiple shock-absorbing pads 30 to multiple weighing switches 50 into a whole. Subsequently, the foot protection plate assembly 14 is installed onto one of the bent plate portions 120 of the car floor plate 12. Finally, the lower sealing plate 60 is fixed to the reinforcing ribs 13 with bolts.

[0062] In addition, this application also provides an elevator, including the car bottom platform 100 described above.

[0063] 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.

[0064] 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.
