Utility Model Content

[0003] In view of this, it is necessary to provide a car top wheel installation structure and an elevator which have a compact structure and can save the top floor space required for the installation of the upper beam assembly.

[0009] It can be understood that the shock-absorbing pad is arranged in the upper beam reinforcement plate fixedly connected to the upper beam assembly, so that the upper beam assembly can contact the outer peripheral wall of the shock-absorbing pad through the upper beam reinforcement plate. In this way, the contact area between the shock-absorbing pad and the upper beam assembly can be increased, which can enhance the shock-absorbing effect of the shock-absorbing pad when it is assembled on the car top wheel shaft and disperse the local stress on the upper beam assembly due to supporting the car top wheel shaft.

[0010] In one embodiment, the upper beam assembly is provided with a wheel axle mounting hole, the upper beam reinforcement plate is arranged on one side of the upper beam assembly and is located at the position of the wheel axle mounting hole, and has a through hole coaxially arranged with the wheel axle mounting hole; the shock-absorbing pad is embedded in the through hole of the upper beam reinforcement plate;

[0012] It can be understood that the upper beam reinforcement plate is installed to the position of the axle mounting hole on the upper beam assembly for the car top wheel axle to pass through, so that the upper beam reinforcement plate can be aligned with the axle mounting hole and assembled to the upper beam assembly. In this way, the assembly position of the upper beam reinforcement plate when assembled on the upper beam assembly can be determined, so as to facilitate the assembly of the upper beam reinforcement plate to the upper beam assembly; further, the upper beam reinforcement plate is installed on one side of the upper beam assembly, such as on the inner side or outer side of the upper beam assembly, so that it can enhance the supporting effect of the upper beam assembly while not increasing the installation space required for the upper beam assembly in the height direction.

[0013] In one embodiment, the upper beam assembly includes two upper beams, the two upper beams are arranged in parallel, the car top wheel is rotatably installed between the two upper beams through the corresponding car top wheel shafts; an accommodating cavity is formed between the two upper beams, and the car top wheel is at least partially arranged in the accommodating cavity;

[0017] It can be understood that the center line of the car top wheel shaft is set on the median plane of the upper beam assembly in the height direction. In this way, the overlapping space between the car top wheel and the upper beam assembly in the height direction of the upper beam assembly can be maximized, which can effectively save the top floor space required when the car top wheel is installed on the upper beam assembly.

[0019] The car top wheel installation structure also includes a limiting member, which is arranged on the upper beam assembly and is connected to the two car top wheel shafts at the same time to limit the relative displacement between the two car top wheels in the horizontal direction.

[0020] It can be understood that the two car top wheel shafts are connected by a stopper, so that the two car top wheel shafts can be prevented from approaching each other when subjected to force due to actual production and installation deviations, thereby ensuring the shock absorption effect when the car top wheel is installed on the upper beam reinforcement plate. Further, the stopper and the upper beam reinforcement plate can be respectively arranged on both sides of the upper beam assembly to make the car top wheel installation structure more compact.

[0021] In one embodiment, the position-limiting member is connected to each of the car top wheel shafts by a plurality of second fasteners;

[0022] Wherein, a plurality of the second fasteners are arranged at intervals along the radial direction of the car top wheel shaft.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, a car top wheel installation structure 100 provided in an embodiment of the present application includes an upper beam assembly 10, a car top wheel 20 and a car top wheel shaft 30. The car top wheel 20 and the car top wheel shaft 30 are arranged correspondingly, and the car top wheel 20 can be rotatably installed between the upper beam assembly 10 through the corresponding car top wheel shaft 30; a shock absorbing pad 40 is installed at the matching position between the car top wheel shaft 30 and the upper beam assembly 10, and the shock absorbing pad 40 is circumferentially wrapped around the outer peripheral surface of the car top wheel shaft 30, and the car top wheel shaft 30 is installed on the upper beam assembly 10 through the shock absorbing pad 40; wherein the shock absorbing pad 40 is arranged in the area where the upper beam assembly 10 is located. In one embodiment, the shock absorbing pad 40 is an integrated structure, and is arranged as a set with shock absorbing and buffering functions such as a rubber sleeve, a silicone sleeve, etc.; in other embodiments, the shock absorbing pad 40 can also be arranged separately.

[0043] It can be understood that the shock-absorbing pad 40 for shock-absorbing the installation of the car top wheel shaft 30 on the upper beam assembly 10 is arranged in the area where the upper beam assembly 10 is located, especially, the shock-absorbing pad 40 is circumferentially wrapped around the car top wheel shaft 30, which not only can make it play a shock-absorbing role in all directions, but also makes the installation of the shock-absorbing pad 40 does not occupy the space of the upper beam assembly 10 in the height direction, so that the car top wheel installation structure 100 can be used in an environment with a small top floor space, which has the advantage of expanding the application scene of the car top wheel installation structure 100. At the same time, the shock-absorbing pad 40 can be an integrated structure, with an annular inner hole set and passed through the car top wheel shaft 30. The annular inner hole structure of the shock-absorbing pad 40 can reduce the shock of the installation of the car top wheel shaft 30 on the upper beam assembly 10 in all directions, which has the effect of improving the shock-absorbing effect when the car top wheel 20 is installed on the upper beam assembly 10; the shock-absorbing pad 40 can also be a petal-shaped structure arranged on the four sides of the car top wheel shaft 30; further, the outer shape of the shock-absorbing pad 40 can be different structures such as round, polygonal, and special-shaped.

[0044] like Figure 1 , Figure 5 As shown, in one embodiment, the upper beam assembly 10 includes two upper beams 11, the two upper beams 11 are arranged in parallel, the number of the car top wheels 20 is two, the number of the car top wheel shafts 30 is also two, the two car top wheels 20 correspond to the two car top wheel shafts 30 one by one, and the car top wheels 20 are rotatably installed between the two upper beams 11 through the corresponding car top wheel shafts 30. Among them, the two upper beams 11 enclose a receiving cavity 101, and the car top wheels 20 are at least partially arranged in the receiving cavity 101. Here, the upper beam 11 is set as a channel steel, and the C-shaped opening grooves of the two channel steels are arranged back to back, that is, the C-shaped opening grooves are arranged outward.

[0045] like Figure 5As shown, in this embodiment, the upper beam assembly 10 further includes a U-shaped bracket 12, which is disposed in the accommodating cavity 101 and connected to the two upper beams 11 respectively, so that the two upper beams 11 can be arranged in parallel. Here, there are two U-shaped brackets 12, and the two U-shaped brackets 12 are arranged on both sides of the two upper beams 11.

[0046] like Figure 1 As shown, in this embodiment, the upper beam assembly 10 also includes a cover plate 13, which is arranged on the outside of the accommodating cavity 101 and located between the two car top wheels 20, and the cover plate 13 is respectively connected to the two upper beams 11, so as to connect and support the two upper beams 11, so as to further improve the stability of the two upper beams 11 when they are maintained in a parallel arrangement.

[0047] like Figure 2 , Figure 3 As shown, in one embodiment, the car top wheel mounting structure 100 further includes an upper beam reinforcement plate 50, which is fixedly connected to the upper beam assembly 10; the upper beam reinforcement plate 50 is arranged corresponding to the shock absorbing pad 40, and the shock absorbing pad 40 is arranged in the corresponding upper beam reinforcement plate 50. In other words, the upper beam assembly 10 of the car top wheel mounting structure 100 of this embodiment uses the upper beam reinforcement plate 50 to realize the installation support of the shock absorbing pad 40.

[0048] It can be understood that the shock-absorbing pad 40 is arranged in the upper beam reinforcement plate 50 fixedly connected to the upper beam assembly 10, so that the upper beam assembly 10 can contact the outer peripheral wall (not shown) of the shock-absorbing pad 40 through the upper beam reinforcement plate 50. In this way, the contact area between the shock-absorbing pad 40 and the upper beam assembly 10 can be increased, which can enhance the shock-absorbing effect of the shock-absorbing pad 40 when assembled on the car top wheel shaft 30, and disperse the local stress of the upper beam assembly 10 due to supporting the car top wheel shaft 30.

[0049] like Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, an axle mounting hole 111 is provided on the upper beam assembly 10, and specifically, the axle mounting holes 111 are respectively provided on the two upper beams 11, and the upper beam reinforcement plate 50 is arranged on one side of the upper beam assembly 10 and is located at the position of the axle mounting hole 111, and has a through hole 52 coaxially arranged with the axle mounting hole 111; the shock-absorbing pad 40 is embedded in the through hole 52 of the upper beam reinforcement plate 50; wherein, the part of the car top axle 30 through which the shock-absorbing pad 40 is passed is arranged through the upper beam reinforcement plate 50 and the axle mounting hole 111. That is to say, the upper beam reinforcement plate 50 can be aligned with the wheel axle mounting hole 111 and assembled to the upper beam assembly 10. In this way, the assembly position of the upper beam reinforcement plate 50 when assembled on the upper beam assembly 10 can be determined, so as to facilitate the assembly of the upper beam reinforcement plate 50 to the upper beam assembly 10; further, the upper beam reinforcement plate 50 is installed on one side of the upper beam assembly 10, such as on the inner side or outer side of the upper beam assembly 10, so that it can enhance the supporting effect of the upper beam assembly 10 without increasing the installation space required for the upper beam assembly 10 in the height direction.

[0050] like Figure 1 , Figure 2 As shown, in one embodiment, the upper beam reinforcement plate 50 is connected to the upper beam assembly 10 through a plurality of first fasteners 51; wherein the plurality of first fasteners 51 are arranged at intervals along the circumferential direction of the car top wheel shaft 30, so that the stability of the upper beam reinforcement plate 50 when installed on the upper beam assembly 10 can be improved. Here, the upper beam reinforcement plate 50 is specifically fixedly connected to the upper beam 11 of the upper beam assembly 10 by the first fasteners 51 located at the four corners of the upper beam reinforcement plate 50, wherein the first fasteners 51 are set as screws or bolts, and the number of the first fasteners 51 is four. In other embodiments, the number of the first fasteners 51 can also be two, three, five, or even more. Of course, the upper beam reinforcement plate 50 can also be fixed to the upper beam assembly 10 by welding, which will not be elaborated here.

[0051] like Figure 1 , Figure 3 As shown, in one embodiment, the two car top wheels 20 are at least partially disposed in the accommodation cavity 101 formed between the two upper beams 11; wherein, the upper beam reinforcement plate 50 is disposed in the accommodation cavity 101, so that the installation of the upper beam reinforcement plate 50 on the upper beam assembly 10 does not occupy the external space of the upper beam assembly 10, so that the structure of the car top wheel installation structure 100 can be compact. Of course, in other embodiments, the upper beam reinforcement plate 50 can also be disposed on the outside of the upper beam assembly 10, or part of the upper beam reinforcement plate 50 can be disposed between the two upper beam assemblies 10, and the remaining part can be disposed on the outside of the upper beam assembly 10, which will not be elaborated here.

[0052] like Figure 2As shown, in one embodiment, the center line of the car top wheel shaft 30 is set on the middle dividing plane of the upper beam assembly 10 in the height direction. That is to say, the car top wheel shaft 30 is arranged at the half position of the height of the upper beam assembly 10, so that the overlapping space between the car top wheel 20 and the upper beam assembly 10 in the height direction of the upper beam assembly 10 can be maximized, which can effectively save the top floor space required when the car top wheel 20 is installed on the upper beam assembly 10. Of course, in other embodiments, the arrangement position of the car top wheel shaft 30 in the height direction of the upper beam assembly 10 can be adjusted arbitrarily according to needs, which will not be elaborated here.

[0053] like Figure 1 , Figure 2 As shown, in one embodiment, the car top wheel installation structure 100 further includes a stopper 60, which is arranged on the upper beam assembly 10 and is connected to the two car top wheel shafts 30 at the same time. Here, the stopper 60 is arranged on the outer side of the upper beam assembly 10, and specifically, the stopper 60 can be set as a channel steel, which is installed on the outer side of the upper beam assembly 10 in a limited manner, that is, just accommodated in the C-shaped opening of the channel steel upper beam, further reducing the overall structure volume and making its assembly structure compact. In this way, the two car top wheel shafts 30 can be prevented from approaching each other, so that the shock absorption effect of the car top wheel 20 when it is installed on the upper beam reinforcement plate 50 can be ensured. This is because there are deviations in the actual production and assembly of the car top wheel installation structure 100, which may cause the force on the car top wheel shaft 30 to be not vertical, thereby causing the force on the shock absorbing pad 40 to be not vertical, which will cause the shock absorbing pad 40 to have a poor shock absorption effect on the car top wheel shaft 30.

[0054] like Figure 1 , Figure 2 As shown, in this embodiment, the stopper 60 is connected to each of the top wheel shafts 30 by a plurality of second fasteners 61; wherein the plurality of second fasteners 61 are arranged at intervals along the radial direction of the top wheel shaft 30. Here, the second fasteners 61 are set as screws or bolts, and the number of the second fasteners 61 is two. In other embodiments, the number of the second fasteners 61 may also be three or even more. Of course, the stopper 60 may also be fixed to the top wheel shaft 30 by welding.

[0055] It can be understood that the connection between the limiting member 60 and the car top wheel shaft 30 is realized by using a plurality of second fasteners 61 arranged at intervals along the radial direction of the car top wheel shaft 30, so that the circumferential limitation between the car top wheel shaft 30 and the limiting member 60 can be achieved, thereby preventing the car top wheel shaft 30 from rotating.

[0056] like Figure 1 , Figure 2 and Figure 4As shown, in one embodiment, a rope-blocking rod 70 is connected to the upper beam assembly 10, and the rope-blocking rod 70 is arranged at the tangent point position of the steel wire rope (not shown) entering the groove and / or the tangent point position of the steel wire rope exiting the groove on the car top wheel 20 to limit the steel wire rope from escaping the rope groove 21 of the car top wheel 20, so that the car top wheel mounting structure 100 is applied to the elevator, and the stability of the car top wheel 20 when driving the elevator car (not shown) to rise and fall can be improved. Here, long grooves 112 are provided on the two upper beams 11 of the upper beam assembly 10, and the rope-blocking rod 70 is arranged through the corresponding long grooves 112, so that the rope-blocking rod 70 can move relative to the two upper beams 11 along the length direction of the long grooves 112 to meet the use requirement of the rope-blocking rod 70 to limit the steel wire rope from escaping the rope groove 21 of the car top wheel 20. It should be noted that the rope-blocking rod 70 can be arranged through the two upper beam assemblies 10, so that the rope-blocking rod 70 can limit the steel wire rope in each rope groove 21 on the car top wheel 20.

[0057] like Figure 1 , Figure 2 As shown, in one embodiment, the car top wheel installation structure 100 further includes an upper protective cover 81, which is arranged above the two upper beam assemblies 10 and connected to the two upper beam assemblies 10, and is used to cover the portion of the car top wheel 20 extending upward relative to the two upper beam assemblies 10; and / or, the car top wheel installation structure 100 further includes a lower protective cover 82, which is arranged below the two upper beam assemblies 10 and connected to the two upper beam assemblies 10, and is used to cover the portion of the car top wheel 20 extending downward relative to the two upper beam assemblies 10. In this way, the car top wheel 20 can be protected. Here, the cover plate 13 used for connecting the two upper beams 11 is arranged at a position between the two upper protective covers 81.

[0058] The present application also provides an elevator, comprising the above-mentioned car top wheel mounting structure 100.

[0059] In summary, the car top wheel mounting structure 100 and the elevator for which protection is sought in the present application, have a shock-absorbing pad 40 for damping the installation of the car top wheel shaft 30 on the upper beam assembly 10 disposed in the area where the upper beam assembly 10 is located. In particular, the shock-absorbing pad 40 is circumferentially wrapped around the car top wheel shaft 30, which not only enables it to have a shock-absorbing effect in all directions, but also ensures that the installation of the shock-absorbing pad 40 does not occupy the space of the upper beam assembly 10 in the height direction, so that the car top wheel mounting structure 100 can be used in an environment with a small top-level space, thereby expanding the application scenarios of the car top wheel mounting structure 100.

[0060] 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.
