[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
[0035] Embodiments of this application provide a guide shoe configured to slide in conjunction with a guide rail, wherein the guide rail has side guide surfaces located on opposite sides and a middle guide surface located between the two side guide surfaces, such as... Figure 1 and Figure 2 As shown, the guide shoe includes: a mounting base 1, a first roller 2, a second roller 3, and a sliding guide 4 with a sliding surface mounted on the mounting base 1.
[0036] The axes of the first roller 2 and the second roller 3 are perpendicular. The sliding surface of the sliding guide 4 is set to be opposite to the circumferential surface of the first roller 2, so that the first roller 2 rolls in cooperation with the side guide surface on one side of the guide rail, the sliding surface of the sliding guide 4 slides in cooperation with the side guide surface on the other side of the guide rail, and the second roller 3 rolls in cooperation with the middle guide surface of the guide rail.
[0037] The guide shoe provided in the embodiments of this application can be applied to the car of a heavy-duty elevator. When the car runs along the guide rail, the first roller 2 and the second roller 3 respectively cooperate with the two mutually perpendicular guide rail surfaces to roll. The sliding guide 4 cooperates with the guide surface on one side of the guide rail to slide. The sliding guide 4 can resist the eccentric load of the car and prevent the car from being eccentrically loaded. Therefore, the guide shoe provided in this application can realize the rolling cooperation between the guide shoe and the guide rail of the heavy-duty elevator to reduce friction, thereby increasing the running speed of the heavy-duty elevator and preventing the heavy-duty elevator from being eccentrically loaded.
[0038] The guide shoe provided in this application can be configured as a type A guide shoe and a type B guide shoe. Type A guide shoe 10A is configured such that the first roller 2 is located on the side where the first end face 31 of the second roller 3 is located, and the sliding guide 4 is located on the side where the second end face 32 of the second roller 3 is located. Type B guide shoe 10B is configured such that the first roller 2 is located on the side where the second end face 32 of the second roller 3 is located, and the sliding guide 4 is located on the side where the first end face 31 of the second roller 3 is located. For example... Figure 1 A type A guide shoe 10A is shown in one embodiment. Figure 2 The image shows a type B guide shoe 10B in one embodiment. Thus, type A guide shoes 10A and type B guide shoes 10B can be used together on the elevator car. For example, type A guide shoes 10A are installed on one side of the bottom of the elevator, and type B guide shoes 10B are installed at the corresponding position on the other side. In this way, when a heavy load enters the elevator, and the heavy load exerts gravity on either side, the sliding guide 4 of one guide shoe will cooperate with the guide rail to prevent the elevator from being unbalanced.
[0039] In one embodiment, the sliding guide 4 may include a sliding body 41 and a wear-resistant component 42 disposed on the sliding body 41, wherein the outer surface of the wear-resistant component 42 is a sliding surface that mates with the guide rail. The sliding body 41 may include a T-shaped structure fixed to the mounting base 1, such as... Figure 1 and Figure 2 As shown, multiple reinforcing ribs are provided at the right angle on one side of the T-shaped structure, and the right angle on the other side is set to stop the installation of the wear-resistant part 42.
[0040] In one embodiment, the guide shoe may further include a first elastic component and a second elastic component. The first roller 2 is configured to abut against the guide rail under the elastic force of the first elastic component, and the second roller 3 is configured to abut against the guide rail under the elastic force of the second elastic component. The structure that allows the roller to abut against the guide rail by providing an elastic component is a common structure in elevator guide shoes. For example, the roller can be mounted on a movable frame that can move relative to the mounting base 1, and the elastic component is configured to apply an elastic force to the movable frame, so that the roller can abut against the guide rail under the action of the elastic component. The specific mounting structures of the first roller 2 and the first elastic component, as well as the specific mounting structures of the second roller 3 and the second elastic component, are not described in detail here.
[0041] Embodiments of this application also provide a car device, such as Figures 3-10 As shown, the system includes a car and multiple guide shoes as described above. Some of the guide shoes are type A guide shoes 10A, and some are type B guide shoes 10B.
[0042] Among them, the type A guide shoe 10A is configured such that the first roller 2 is located on the side of the first end face 31 of the second roller 3, and the sliding guide 4 is located on the side of the second end face 32 of the second roller 3; the type B guide shoe 10B is configured such that the first roller 2 is located on the side of the second end face 32 of the second roller 3, and the sliding guide 4 is located on the side of the first end face 31 of the second roller 3.
[0043] In some implementations, the car has a first car frame 100 near the front end and a second car frame 200 near the rear end; wherein, type A guide shoes 10A and type B guide shoes 10B are respectively installed on the first car frame 100 and the second car frame 200.
[0044] In one embodiment, at two corresponding installation positions on both sides of the car, one of type A guide shoe 10A and type B guide shoe 10B is installed at one installation position, and the other of type A guide shoe 10A and type B guide shoe 10B is installed at the corresponding installation position on the other side. That is, the guide shoes on both sides of the car are arranged substantially symmetrically with respect to the plane in the middle of the two sides. For example, if type A guide shoe 10A is installed at the bottom of one side of the first car frame 100, then type B guide shoe 10B is installed at the bottom of the other side. In this embodiment, the guide shoes on both sides of the car are arranged substantially symmetrically, which allows the guide shoes on both sides to resist the uneven loading of the car when a heavy object enters from either side.
[0045] In one embodiment, at two corresponding mounting positions on the first car frame 100 and the second car frame 200, the first car frame 100 is equipped with one of type A guide shoes 10A and type B guide shoes 10B, and the second car frame 200 is equipped with the other of type A guide shoes 10A and type B guide shoes 10B. That is, the guide shoes on the first car frame 100 and the second car frame 200 are arranged substantially symmetrically with respect to the plane between the two car frames. For example, type B guide shoes 10B are installed on the top of the first side of the first car frame 100, and type A guide shoes 10A are installed on the top of the first side of the second car frame 200.
[0046] The guide shoes on the left and right sides of the car are basically symmetrically arranged, as are the guide shoes on the first car frame 100 and the second car frame 200. This ensures that when a heavy object is pressed down at any position in the car, some of the sliding guide parts 4 of the guide shoes will cooperate with the guide rail to prevent the car from being unbalanced.
[0047] Figure 3 One side of the car assembly in one embodiment is shown. Figure 4The top of the car assembly in this embodiment is shown. In this embodiment, a type A guide shoe 10A is installed at the top and a type B guide shoe 10B is installed at the bottom on one side of the first car frame 100. The guide shoes on both sides of the first car frame 100 are basically symmetrically arranged, that is, a type B guide shoe 10B is installed at the top and a type A guide shoe 10A is installed at the bottom on the other side of the first car frame 100. In this embodiment, the sliding guide 4 of the guide shoe installed at the bottom of the first car frame 100 is located on the forward-facing side of the guide rail. In this way, when a heavy object enters from the front door of the car, and the heavy object applies pressure to either side of the car, causing one front end of the car to tilt downwards, the sliding guide 4 located on the front side of the guide rail will cooperate with the guide rail to resist the tilting of the car.
[0048] Figure 5 One side of the car assembly in one embodiment is shown. Figure 6 The top of the car assembly in this embodiment is shown. In this embodiment, a type B guide shoe 10B is installed on the top of one side of the first car frame 100, and a type A guide shoe 10A is installed on the bottom. The guide shoes on both sides of the first car frame 100 are basically symmetrically arranged, that is, a type A guide shoe 10A is installed on the top of the other side of the first car frame 100, and a type B guide shoe 10B is installed on the bottom. In this embodiment, the first roller 2 of the guide shoe installed at the bottom of the first car frame 100 is located on the forward side of the guide rail.
[0049] In this embodiment, the guide shoe is installed in such a way that when a heavy object enters from the front door of the car, the heavy object applies heavy pressure to either side of the car. Since the first roller 2 of the guide shoe at the bottom of the car is located in front of the guide rail, when the front end of the car tilts downward, the gap between the sliding guide 4 of the guide shoe at the bottom of the car and the guide rail will increase, while the sliding guide 4 of the guide shoe at the top of the car will cooperate with the guide rail to resist the downward tilt of the car.
[0050] Figure 7 One side of the car assembly in one embodiment is shown. Figure 8 The top of the car assembly in this embodiment is shown. In this embodiment, type A guide shoes 10A are installed on both the bottom and top of one side of the first car frame 100; the guide shoes on both sides of the first car frame 100 are basically symmetrically arranged, that is, type B guide shoes 10B are installed on both the bottom and top of the other side of the first car frame 100; wherein, in this embodiment, the first roller 2 of the guide shoe installed at the bottom of the first car frame 100 is located on the forward side of the guide rail. In this way, after the heavy object enters the front door, that is, when the heavy object enters the car, the sliding guide 4 in the guide shoe at the bottom of the first car frame 100, located behind the guide rail, can cooperate with the guide rail to effectively resist the tilting of the car.
[0051] Figure 9 One side of the car assembly in one embodiment is shown. Figure 10Shows the top of the car device in this embodiment. In this embodiment, on one side of the first car frame 100, B-type guide shoes 10B are installed at both the bottom and the top; the guide shoes on both sides of the first car frame 100 are arranged symmetrically, that is, A-type guide shoes 10A are installed at both the bottom and the top on the other side of the first car frame 100; among them, in this embodiment, the sliding guide 4 of the guide shoe installed at the bottom of the first car frame 100 is located on the forward side of the corresponding guide rail. In this way, when a heavy object enters through the front door of the car, when the heavy object applies a heavy pressure on either side of the car and one side front end of the car tilts downward, the sliding guide 4 of the guide shoe at the bottom of the car, due to being located on the front side of the guide rail, will cooperate with the corresponding guide rail to resist the tilt of the car, while the sliding guide 4 of the guide shoe at the top of the car is located on the rear side of the guide rail, and when the front end of the car tilts downward, it will also cooperate with the guide rail to resist the tilt of the car. That is to say, in this embodiment, the sliding guides 4 of the guide shoes at the top and bottom of the first car frame 100 will both cooperate with the guide rail to resist the tilt of the car.
[0052] Of course, the arrangement of the guide shoes on the car is not limited to the above description, and the A-type guide shoes 10A and B-type guide shoes 10B can be set according to the specific use scenarios of each elevator.
[0053] In one embodiment, a third car frame 300 can also be provided between the first car frame 100 and the second car frame 200. A sliding guide shoe or a rolling guide shoe that cooperates with the guide rail is installed on the third car frame 300, and the sliding guide shoe or the rolling guide shoe therein can be the commonly used sliding guide shoe or rolling guide shoe in the prior art.
[0054] The embodiment of the present application can facilitate reducing the problem of car partial load by providing the third car frame 300 and arranging a guide shoe on the third car frame 300 to cooperate with the guide rail.
[0055] The embodiment of the present application also provides an elevator, including the car device as described above.
