Description

Technical Field

[0001] The utility model belongs to the technical field related to elevators, and particularly relates to a car bottom wheel car frame and an elevator. Background Art

[0002] With the improvement of people's living standards, there are more villas or single-family houses, and most families have begun to install home elevators. Moreover, most elderly people in families have difficulty climbing stairs and other movements, so they choose to install home elevators in their homes.

[0003] For current villas or single-family houses, the internal area is extremely valuable and the top floor space is relatively cramped, so the limitations of the shaft must be taken into account during the design; due to the lack of top floor space, current conventional car frames cannot meet the demand, and most of them will use a car bottom wheel car frame structure to meet the lower top floor space requirements.

[0004] Considering the existing car bottom wheel car frame structure, when a home elevator adopts the car bottom wheel car frame structure, first, a support beam must be used to connect the straight beams on both sides, and an upper safety clamp lifting mechanism must be installed on the support beam, so that the existing home elevator still has the problem of limited top floor space after adopting the car bottom wheel car frame structure; second, the existing car bottom wheel car frame structure, the car bottom wheels are hung under the car bottom platform, so that this structure still has the problem of limited pit space. Therefore, it is particularly necessary to develop a car bottom wheel car frame suitable for low top floors. Utility Model Content

[0008] A straight beam assembly is arranged on both sides of the car top, and the straight beam assembly includes a single straight beam, one end of which is fixedly connected to the car top;

[0009] The car bottom platform assembly comprises a single-support car bottom and a car bottom wheel assembly. The single-support car bottom is arranged on one end of the single straight beam away from the car top and is simultaneously connected to the single straight beam located on both sides of the car top. The car bottom wheel assembly is installed on the single-support car bottom.

[0010] It can be understood that the single straight beam is directly connected to the car roof, and the car bottom wheel assembly is installed on the single-support car bottom, so that the car bottom wheel frame eliminates the upper beam used to connect the two single straight beams. This can reduce the overall height of the car bottom wheel frame and achieve the purpose of reducing the top floor space, so that the elevator using the car bottom wheel frame can be suitable for installation in the low-top hoistway.

[0023] In one of the embodiments, the installation position between the buffer striker plate and the support beam can be adjusted along the thickness direction of the buffer striker plate.

[0024] It can be understood that by adjusting the installation position between the buffer striker plate and the support beam, the position of the buffer striker plate when supporting the support beam can be adjusted, so that the buffer striker plate can be suitable for supporting support beams with different deformation amounts, which can further ensure the parallelism of the two car bottom wheel assemblies when assembled on the single-support car bottom.

[0025] In one embodiment, the car bottom wheel car frame further includes a guide shoe and a safety clamp, and the guide shoe and the safety clamp are both installed on the single straight beam.

[0028] It can be understood that the safety clamp and the guide shoe are at least partially arranged in the accommodating cavity of the single straight beam, so that the safety clamp and the guide shoe can share the dimension in the width direction of the car bottom wheel frame with the single straight beam, which has the effect of reducing the dimension in the width direction of the car bottom wheel frame.

[0029] In one of the embodiments, the car platform assembly further includes a safety clamp lifting mechanism, which is disposed in the area where the single-support car platform is located and connected to the single-support car platform.

[0030] It can be understood that the safety clamp lifting mechanism is arranged in the area where the single-support car platform is located, so that the safety clamp lifting mechanism can be assembled into the single-support car platform in an embedded manner, so that the assembly of the safety clamp lifting mechanism does not need to occupy space in the thickness direction of the single-support car platform, thereby reducing the overall height of the car platform assembly and achieving the purpose of reducing the depth of the pit, so that the elevator using the car platform wheel frame can be suitable for installation in shallow-level hoistways.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0046] like Figure 1 , Figure 3 As shown, a car frame with car bottom wheels 100 provided in one embodiment of the present application comprises a car top 10, a straight beam assembly 20 and a car bottom platform assembly 30, wherein the straight beam assembly 20 is arranged on both sides of the car top 10, and the straight beam assembly 20 comprises a single straight beam 21, and one end of the single straight beam 21 is fixedly connected to the car top 10; the car bottom platform assembly 30 comprises a single-support car bottom 31 and a car bottom wheel assembly 32, wherein the single-support car bottom 31 is arranged on one end of the single straight beam 21 away from the car top 10 and is simultaneously connected to the single straight beam 21 located on both sides of the car top 10, and the car bottom wheel assembly 32 is installed on the single-support car bottom 31.

[0047] As can be seen from the above, the single straight beam 21 is directly connected to the car roof 10, and the car bottom wheel assembly 32 is installed on the single-support car bottom 31, so that the car bottom wheel car frame 100 cancels the upper beam used to connect the two single straight beams 21, which can reduce the overall height of the car bottom wheel car frame 100 and achieve the purpose of reducing the top floor space, so that the elevator using the car bottom wheel car frame 100 can be suitable for installation in the low top floor shaft. Here, the car roof 10 is the car roof of the elevator car, and the single-support car bottom 31 is used to carry the elevator car. It should be noted that when the above-mentioned single straight beam 21 is directly connected to the car roof 10, the structural strength between the two can meet the use requirements of the elevator, which will not be elaborated here.

[0048] like Figure 1 As shown, one end of the single straight beam 21 is attached to the car top 10, and then the car top 10 attached to the single straight beam 21 is fixed by the first bolt 101. Of course, in other embodiments, the single straight beam 21 and the car top 10 can also be fixed by welding.

[0049] like Figure 2 As shown, the car bottom wheel frame 100 also includes a guide shoe 22 and a safety clamp 23, and the guide shoe 22 and the safety clamp 23 are both installed on the single straight beam 21. That is to say, the car bottom wheel frame 100 integrates the guide shoe 22 and the safety clamp 23 on the single straight beam 21, so that the assembly of the guide shoe 22 and the safety clamp 23 does not need to occupy the height direction of the car bottom wheel frame 100. It should be noted that the structures of the guide shoe 22 and the safety clamp 23 can adopt the conventional methods of existing elevators, which will not be elaborated here. Here, the number of single straight beams 21 in each straight beam assembly 20 is two, and the two guide shoes 22 are arranged on the upper and lower sides of the single straight beam 21.

[0050] As preferably, Figure 2 , Figure 4 As shown, the single straight beam 21 is formed with an accommodation cavity 211 inwardly, and the safety clamp 23 and the guide shoe 22 are at least partially arranged in the accommodation cavity 211. That is, the guide shoe 22 and the safety clamp 23 are arranged on the single straight beam 21 in an internal manner, so that the safety clamp 23 and the guide shoe 22 can share the size of the single straight beam 21 in the width direction of the car bottom wheel car frame 100, which has the effect of reducing the size of the car bottom wheel car frame 100 in the width direction.

[0051] like Figure 4 As shown, the car bottom wheel car frame 100 also includes a fixing member 102, and the single straight beam 21, the safety clamp 23 and the single supporting car bottom 31 are fixed by the fixing member 102. The assembly of the safety clamp 23 on the single straight beam 21 and the assembly of the single straight beam 21 between the single supporting car bottom 31 can be completed at one time through the fixing member 102, which can facilitate the assembly connection between the single straight beam 21, the safety clamp 23 and the single supporting car bottom 31. Here, the fixing member 102 is configured as a bolt, a screw, a latch, etc.

[0052] like Figures 2 to 4As shown, the car bottom wheel assembly 32 is at least partially arranged in the area where the single-support car bottom 31 is located; wherein the single-support car bottom 31 is provided with a guide hole (not shown); the car bottom wheel assembly 32 includes a guide wheel 321, which is arranged corresponding to the guide hole, and the guide wheel 321 is arranged to protrude outward relative to the corresponding guide hole. In other words, the car bottom wheel assembly 32 is assembled into the single-support car bottom 31 in an embedded manner, so that the assembly of the car bottom wheel assembly 32 does not need to occupy space in the thickness direction of the single-support car bottom 31, so that the overall height of the car bottom platform assembly 30 can be reduced, and the purpose of reducing the depth of the pit can be achieved, so that the elevator using the car bottom wheel car frame 100 can be suitable for installation in a shallow-level shaft. It should be noted that the guide wheel 321 on the car bottom wheel assembly 32 protrudes outward from the guide hole on the single-support car bottom 31, so as to avoid interference between the transmission belt wrapped around the guide wheel 321 and the single-support car bottom 31. Here, the number of the car bottom wheel assemblies 32 is configured to be at least two, and at least two car bottom wheel assemblies 32 are arranged in parallel to meet the use requirements of the elevator.

[0053] like Figure 5 , Figure 6 As shown, there are two guide wheels 321 in each car bottom wheel assembly 32, and the car bottom wheel assembly 32 also includes two support beams 322. The two guide wheels 321 are arranged between the two support beams 322 and are rotatably connected to the support beams 322 respectively; wherein the guide wheels 321 are eccentrically arranged relative to the support beams 322. This allows the guide wheels 321 to protrude outward from the support beams 322, thereby avoiding position interference between the transmission belt wound on the guide wheels 321 and the single-support car bottom 31, and meeting the use requirements of the car bottom wheel assembly 32 assembled on the single-support car bottom 31. Here, each support beam 322 can be fixedly connected to the single-support car bottom 31 by a second bolt 103.

[0054] As preferably, Figures 5 to 7 As shown, an eccentric hole 3221 is provided on the support beam 322, and a rotating shaft 3211 is provided on the guide wheel 321, and the rotating shaft 3211 can be plugged and matched with the eccentric hole 3221; wherein, the car bottom wheel assembly 32 also includes a clamping plate 323, which is fixedly connected to the support beam 322 and clamped with the rotating shaft 3211, and is used to limit the guide wheel 321 to the support beam 322, and realize the assembly of the guide wheel 321 on the support beam 322 to limit the position, so as to meet the use requirements of assembling the guide wheel 321 on the support beam 322. Here, the clamping plate 323 and the support beam 322 are connected by the third bolt 104. Of course, in other embodiments, the clamping plate 323 and the support beam 322 can also be connected and fixed by welding.

[0055] like Figure 3As shown, the car bottom platform assembly 30 also includes a buffer striker 33, which is arranged between two adjacent car bottom wheel assemblies 32 and connected to the support beam 322. The buffer striker 33 can play a structural support role for the support beams 322 in the two car bottom wheel assemblies 32, so that the parallelism of the two car bottom wheel assemblies 32 when assembled on the single-support car bottom 31 can be ensured, and the guide wheels 321 in the two car bottom wheel assemblies 32 are made coaxial to meet the use requirements of the elevator. Here, the buffer striker 33 can be specifically connected to one support beam 322 in the two car bottom wheel assemblies 32 respectively through the bolt assembly 105. Here, the buffer striker 33 is set as a sheet metal part, and the buffer striker 33 can collide with the elevator car that is lowered into place in the elevator with the car bottom wheel car frame 100, and play a buffering role for the elevator car.

[0056] Preferably, along the thickness direction of the buffer striker plate 33, the installation position between the buffer striker plate 33 and the support beam 322 can be adjusted, so that the position of the buffer striker plate 33 when supporting the support beam 322 can be adjusted, so that the buffer striker plate 33 can be suitable for supporting the support beam 322 with different deformations, which can further ensure the parallelism of the two car bottom wheel assemblies 32 when assembled on the single-support car bottom 31, and make the guide wheels 321 in the two car bottom wheel assemblies 32 coaxial to meet the use requirements of the elevator. Here, the purpose of adjusting the installation position between the buffer striker plate 33 and the support beam 322 can be achieved by increasing or decreasing the gasket (not shown) between the buffer striker plate 33 and the support beam 322.

[0057] like Figure 3 As shown, the car platform assembly 30 further includes a safety clamp lifting mechanism 34, which is arranged in the area where the single-support car platform 31 is located and connected to the single-support car platform 31. In other words, the safety clamp lifting mechanism 34 is also assembled into the single-support car platform in an embedded manner, so that the assembly of the safety clamp lifting mechanism 34 does not need to occupy space in the thickness direction of the single-support car platform 31, which can reduce the overall height of the car platform assembly and achieve the purpose of reducing the depth of the pit, so that the elevator using the car platform wheel frame can be suitable for installation in a shallow hoistway.

[0058] In addition, the present application also provides an elevator, comprising the above-mentioned car bottom wheel car frame 100.

[0059] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, 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.

[0060] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
