Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower crane maintenance technology, and in particular to a method for separating the slewing motor and coupler of a tower crane. Background Technology
[0002] Tower cranes are indispensable lifting equipment in the construction industry, and their application is becoming increasingly widespread with the development of the industry. During operation, tower cranes face complex and harsh environments and working conditions, frequently requiring maintenance of the slewing motor. This maintenance involves separating the slewing motor from the hydraulic coupler. The slewing motor and coupler are connected and transmit power via an interference fit and keyway, making disassembly difficult. Traditional disassembly methods, such as hammering and prying, easily damage the coupler and motor housings, cause misalignment of the connecting shafts, and other quality defects, while also wasting manpower and resources.
[0003] Therefore, a device for separating the slewing motor and coupler of a tower crane was developed, which can replace the traditional methods of manual hammering and prying, thereby improving work quality and efficiency. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] The technical problem to be solved by this utility model of a tower crane slewing motor and coupler separation device is to realize the mechanized separation of the tower crane slewing motor and coupler, which can improve maintenance quality, increase labor efficiency and reduce labor intensity.
[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, this utility model provides a separation device for the slewing motor and coupler of a tower crane, comprising: a main frame, a hydraulic station, an oil jack, a separation wedge A, a separation wedge B, and a support base; the main frame is welded from steel plates and square tubes; the hydraulic station, consisting of an oil tank, an oil pump, a valve group, and an electric motor, is installed in the main frame to provide power to the oil jack; the oil jack is installed on the main frame and connected to the separation wedge A; the separation wedge A, welded from steel plates and round steel, is connected to the oil jack; the separation wedge B, welded from steel plates and round steel, is installed on the support base; the support base, welded from steel plates, is installed on the main frame and is used to install and support the separation wedge B.
[0008] Preferably, the separating wedge A is made of 45# steel plate with a thickness of 30mm and 45# round steel with a diameter of 30mm after welding and tempering. The inclined surface is provided with grooves with a depth of 2mm and a width of 2mm that are consistent with the running direction of the oil top. The grooves and the inclined surface are coated with grease to reduce friction and prevent rust.
[0009] Preferably, the separating wedge B is made of 45# steel plate with a thickness of 30mm and 45# round steel with a diameter of 30mm, which are welded and tempered.
[0010] (III) Beneficial Effects
[0011] The application of a separation device between the slewing motor and the coupler in tower cranes enables the mechanized separation of the slewing motor and the coupler, effectively protecting the slewing motor and the coupler from damage, while improving work quality, increasing work efficiency, and reducing labor intensity.

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0015] Figure 1 This is a three-dimensional view of a tower crane rotary motor and coupler separation device according to an embodiment of the present utility model, including: main frame 1, hydraulic station 2, oil top 3, separation wedge A4, separation wedge B5, and support base 6;
[0016] Figure 2 This is a three-dimensional enlarged view of the separating wedge A described in this embodiment of the utility model. The inclined surface is provided with grooves with a depth of 2mm and a width of 2mm that are consistent with the running direction of the oil top.
[0017] The specific working principle is as follows:
[0018] When using a tower crane's slewing motor and coupler separation device, the slewing motor and coupler to be disassembled are hoisted and fitted into the separation wedge B slot of the separation device, with the slewing motor on top and the coupler below. At this time, the connecting shaft between the coupler and the slewing motor is placed into the middle slot of the separation wedge B. Then, the hydraulic station is activated, and the hydraulic jack, receiving power, pushes the separation wedge A into contact with the separation wedge B. The relative movement of the inclined surfaces of separation wedge A and separation wedge B generates a vertical force between the coupler and the slewing motor shaft. As the hydraulic jack advances, a vertical displacement occurs between the coupler and the slewing motor shaft, thereby separating the coupler from the slewing motor shaft.
[0019] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. All equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
