Description
Technical Field
[0001] This utility model relates to the field of elevator technology, and in particular to a special guide shoe for a ceiling-mounted machine room-less elevator. Background Technology
[0002] Elevator guide shoes are sliding guide devices between elevator guide rails and the car or counterweight. They stabilize the car or counterweight on the guide rails, allowing it to move only up and down, preventing the car or counterweight from tilting or swaying during movement, and ensuring the smooth operation of the elevator.
[0003] Guide shoes can be classified into rolling guide shoes, fixed sliding guide shoes, and elastic sliding guide shoes according to their movement between the guide shoe and the working surface of the guide rail. Fixed sliding guide shoes have a simple structure and low cost, but they are prone to vibration and impact during elevator operation.
[0004] The elastic sliding guide shoe has an added adjustable device, and its structure is more complex than that of the fixed sliding guide shoe. It has better working performance, but its cost is also higher than that of the fixed sliding guide shoe. It is usually installed above the upper beam of the car frame. When the guide shoe is installed above the upper beam of the car frame, the requirement for the top floor height of the hoistway is also higher than when it is installed on the side of the upper beam of the car frame. Utility Model Content
[0005] The purpose of this utility model is to provide a top-mounted, machine-room-less elevator guide shoe, which solves the problems that traditional guide shoes, even with the addition of an adjustable device, are more expensive than fixed sliding guide shoes, and that the installation requires a higher ceiling height in the shaft than when installed on the side of the car frame beam.
[0006] To achieve the above objectives, this utility model employs a top-mounted, machine-room-less elevator guide shoe, comprising a welded guide shoe base, a welded guide shoe mounting bracket, and a simple vibration damping installation assembly. The simple vibration damping installation assembly includes a welded guide shoe liner mounting bracket, a guide shoe liner, guide shoe rubber, an M8 hex bolt, a guide shoe baffle, and an upper baffle for the guide shoe liner. The guide shoe liner mounting bracket is welded inside the welded guide shoe base. The M8 hex bolt passes through the upper baffle of the guide shoe liner and is detachably connected to the welded guide shoe liner mounting bracket, and is located at the welded guide shoe liner mounting bracket. On the upper side of the connection, the guide shoe liner is disposed inside the guide shoe liner mounting bracket weld, the guide shoe rubber is disposed on the outer surface of the guide shoe liner mounting bracket weld, the guide shoe baffle is welded to the guide shoe seat and detachably connected to the guide shoe mounting bracket weld, and is located on both sides of the guide shoe seat weld and the guide shoe rubber, the upper baffle of the guide shoe liner is welded and fixedly connected to the guide shoe liner mounting bracket, and is located on the upper side of the guide shoe liner mounting bracket weld away from the guide shoe seat weld, and the upper baffle of the guide shoe liner is perpendicular to the guide shoe baffle.
[0007] The guide shoe for the ceiling-mounted machine room-less elevator also includes a guide shoe mounting bracket welded together and M12 hexagonal bolts. The guide shoe mounting bracket is welded to both sides of the outer side of the guide shoe baffle. The M12 hexagonal bolts pass through the guide shoe mounting bracket welded together and the guide shoe baffle welded to the guide shoe seat for detachment and connection, and are located on both sides of the outer side of the guide shoe baffle.
[0008] The simplified shock absorption mounting assembly also includes an M12 hexagonal nut bolt and a guide shoe locking bolt. The M12 hexagonal nut bolt is detachably connected to the guide shoe mounting bracket and is located inside the welded guide shoe mounting bracket. One end of the guide shoe locking bolt passes through the guide shoe seat and is welded to the guide shoe liner mounting bracket for detachable connection, and is located on the side of the guide shoe liner mounting bracket away from the guide shoe liner.
[0009] The guide shoe seat welding includes a guide shoe seat plate and a guide shoe nut plate. The guide shoe seat plate is detachably connected to the guide shoe baffle and is located inside the guide shoe baffle. The guide shoe nut plate is welded to the guide shoe seat plate and is located on one side inside the guide shoe seat plate.
[0010] The guide shoe mounting bracket welding includes a guide shoe mounting bracket and a guide shoe mounting bracket stiffener. The guide shoe mounting bracket is disposed on both sides of the guide shoe baffle and is perpendicular to the M8 hexagonal bolt. The guide shoe mounting bracket stiffener is welded to the guide shoe mounting bracket and is located at the internal center of the guide shoe mounting bracket.
[0011] The guide shoe rubber includes two side rubbers and a back rubber. The two side rubbers are welded and detached from the guide shoe liner mounting bracket and are located on both sides of the guide rail side welded to the guide shoe liner mounting bracket. The back rubber is welded and detached from the guide shoe liner mounting bracket and is located on one side of the top surface of the guide rail welded to the guide shoe liner mounting bracket. The back rubber is perpendicular to the two side rubbers.
[0012] This utility model discloses a guide shoe for a ceiling-mounted, machine-room-less elevator, comprising a welded guide shoe base, a welded guide shoe mounting bracket, and a simple vibration damping installation assembly. The simple vibration damping installation assembly includes a welded guide shoe liner mounting bracket, a guide shoe liner, guide shoe rubber, an M8 hex bolt, a guide shoe baffle, and an upper baffle for the guide shoe liner. The guide shoe liner mounting bracket is welded inside the welded guide shoe base. The M8 hex bolt passes through the upper baffle of the guide shoe liner and is detachably connected to the welded guide shoe liner mounting bracket, located on the upper side above the welded guide shoe liner mounting bracket. The guide shoe liner is disposed inside the welded guide shoe liner mounting bracket, and the guide shoe rubber is disposed within the guide shoe liner. The outer surface of the mounting bracket is welded, the guide shoe baffle is welded to the guide shoe seat and the guide shoe mounting bracket is welded and detachably connected, and is located on both sides of the guide shoe seat weld and the guide shoe rubber. The upper baffle of the guide shoe liner is welded and fixedly connected to the guide shoe liner mounting bracket, and is located on the upper side of the guide shoe liner mounting bracket weld away from the guide shoe seat weld. The upper baffle of the guide shoe liner is perpendicular to the guide shoe baffle. Due to the addition of a simple shock-absorbing installation component, the problem that the cost of traditional guide shoes is higher than that of fixed sliding guide shoes after the addition of adjustable devices, and the requirement for the top floor height of the shaft during installation is higher than that for installation on the side of the car frame upper beam.
