[0027] Depend on Figure 1 An elevator guide device shown is fixedly installed between the side wall of the elevator shaft and the side wall of the car 1, including a plurality of rails 2 and a plurality of guide shoes. The rail 2 is fixedly connected to the side wall of the elevator shaft. The rail 2 is a hollow cubic structure. A slide groove 3 is provided on the side of the rail 2 close to the car 1. The guide shoe is arranged in the inner cavity of the rail 2 and is fixedly connected to the side wall of the car 1. The guide shoe includes a mounting plate 4 and a guide slide plate 5. One end face of the mounting plate 4 is fixedly connected to the middle part of one side face of the guide slide plate 5 to form a T-shaped block structure as a whole. The side face of the guide slide plate 5 is fixedly connected to the side wall of the car 1. An auxiliary guide slide assembly is fixedly installed on the side face of the guide slide plate 5. The auxiliary guide slide assembly is clearance-matched with the outer side face of the rail 2. The opposite sides of the mounting plate 4 are rotatably connected with guide units respectively. The guide unit is in sliding contact with the inner wall of the rail 2, and the side of the mounting plate 4 away from the guide slide plate 5 is in sliding contact with the inner wall of the rail 2.

[0028] The utility model realizes the movement and guidance of the elevator car 1 by utilizing the sliding of the track 2 and the guide shoe matched with the track 2, and reduces the noise during the operation of the elevator and improves the comfort of the elevator by buffering the vibration of the car during the operation of the guide unit. At the same time, the guide shoe is completely inserted into the track 2, which improves the connection firmness between the guide shoe and the track 2, that is, improves the safety of the elevator operation.

[0029] To further optimize the solution, Figure 2 and 3As shown, the guide unit includes two guide components and a pressing component, the pressing component includes a spring 6 and a guide rod 7, a through hole is opened on the side of the mounting plate 4, the spring 6 passes through the through hole and is fixedly connected to the inner wall of the through hole, the guide rod 7 passes through the inner cavity of the spring 6, the middle of the inner cavity of the spring 6 is fixedly connected to the middle of the side of the guide rod 7, the two ends of the guide rod 7 are respectively slidably connected to the guide components, and the two ends of the spring 6 are respectively abutted against the guide components, so that a certain abutting force is applied to the guide component through the elastic force of the spring 6, so that the guide component can be tightly pressed against the inner cavity side wall of the track 2. The bottom end of the guide component is rotatably connected to the side of the mounting plate 4.

[0030] Further optimization scheme, the guide assembly includes a guide plate 8, the top surface of the guide plate 8 is respectively provided with a clearance groove 9 and two installation grooves, the two installation grooves are symmetrically arranged about the clearance groove 9, and a guide wheel 10 is rotatably connected in the installation groove, and the guide wheel 10 is made of hard rubber material, and the rolling noise of the guide wheel 10 and the track 2 can be reduced by the flexible rubber material. The guide wheel 10 is in sliding contact with the inner wall of the track 2, and the side wall of the clearance groove 9 is in sliding contact with one end of the guide rod 7.

[0031] Furthermore, a groove matched with the guide wheel 10 is formed on the inner wall of the track 2, and the guide wheel 10 rolls in the groove. The guide wheel 10 is guided by the groove, thereby improving the stability of the guide assembly.

[0032] Further optimization scheme, the two opposite sides of the mounting plate 4 are respectively fixedly connected with a wedge-shaped limit plate 11, the guide plate 8 is detachably connected to the limit plate 11, and the horizontal distance between the limit plate 11 and the guide plate 8 when they are in contact is equal to the distance between the side of the mounting plate 4 and the side wall of the chute 3, which can achieve the deviation of the guide assembly due to the external force of the car 1, and can also achieve the stable operation of the car 1 through the guidance of the mounting plate 4 and the side wall of the chute 3. The opposite sides of the mounting plate 4 are respectively matched with the side wall of the chute 3, and the top and bottom surfaces of the mounting plate 4 are respectively chamfered, which reduces the contact pressure when the mounting plate 4 is slidably connected with the side wall of the chute 3, and improves the service life of the side wall of the chute 3.

[0033] To further optimize the solution, Figure 4 As shown, the guide slide 5 is provided with a plurality of oil storage grooves 12 on the side close to the mounting plate 4, and the oil storage grooves 12 are filled with lubricating oil. The auxiliary guide slide assembly includes a guide slide ball 13, and a frame 14 is connected to the outer side of the guide slide ball 13, and the edge of the frame 14 is closed and fixedly connected to the inner wall of the oil storage groove 12, and the guide slide ball 13 is in sliding contact with the frame 14, and the upper and lower adjacent oil storage grooves 12 are connected to each other, and the top surface of the guide slide 5 is fixedly connected to an oil box 15, and the oil box 15 is filled with lubricating oil, and the oil box 15 is slidably connected to a pressure plate 16, and the top surface of the pressure plate 16 is detachably connected to a plurality of counterweights 17, and the inner cavity of the oil box 15 is connected to the oil storage groove 12.

[0034] Furthermore, the side sliding of the guide ball 13 is abutted against a push post, one end of which is fixedly connected to the inner wall of the oil storage groove 12, so that the guide ball 13 can slide smoothly in the frame 14 without falling off.

[0035] A further optimization scheme is that the mounting plate 4 is rotatably connected to the side away from the guide slide plate 5, and the rollers 18 abut and slide against the inner wall of the track 2. The rollers 18 are made of brass or bronze. The rigid rollers 18 are used to abut and limit the mounting plate 4, thereby ensuring the gap between the side of the guide slide plate 5 and the outer side of the track 2, and also improving the operational stability of the guide assembly.

[0036] The working process of this embodiment is as follows:

[0037] When the utility model is running in the car 1, the spring 6 will push the guide plate 8, and the guide wheel 10 connected to the top of the guide plate 8 will contact and slide against the inner wall of the track 2, rolling along the inner wall of the track 2, and the spring 6 will be in a rebound state throughout the whole process, ensuring the contact force between the guide wheel 10 and the track 2. At the same time, when the car 1 vibrates, the spring 6 can stably contact the guide wheel 10 against the track 2, which not only improves the stability of operation, but also reduces the vibration noise of operation.

[0038] When the car 1 vibrates longitudinally, the roller 18 connected to the side of the mounting plate 4 can stably and firmly restrict the car 1 between the two rails 2 to prevent the car 1 from derailing. When the longitudinal vibration of the car 1 is too large, the auxiliary guide assembly will contact the outer side of the rail 2 to prevent the car 1 from being seriously displaced and causing a safety accident.

[0039] The guide ball 13 of the auxiliary guide assembly rolls along the outer side of the track 2. During the rolling process of the guide ball 13, the guide ball 13 will continuously adhere to the lubricating oil filled in the oil storage tank 12 to wet the guide ball 13 and reduce the friction loss of the guide ball 13.

[0040] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
