Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoist lifting technology, specifically to a multi-channel rotating operating platform for hoists. Background Technology
[0002] Currently, hoisting is widely used for equipment lifting operations in various industrial plants. For single lifting scenarios, electric hoists or manual hoists are commonly used as lifting equipment, typically with one steel rail for each hoist to move. For work scenarios where multiple pieces of equipment within the same plant need to be lifted, electric single-girder overhead cranes are usually used.
[0003] The above traditional lifting methods have the following significant drawbacks in practical applications:
[0004] 1. A single lifting device is equipped with only one steel rail for its movement, thus limiting the operating range of the lifting device;
[0005] 2. When multiple devices need to be lifted in a certain work scenario, and a single-beam suspended crane cannot be installed due to the limited space inside the building, multiple hoists are usually required, which is not economically efficient.
[0006] 3. When multiple hoists are installed inside a building, the equipment to be lifted needs to be transferred between multiple hoists, which results in low work efficiency and poses a significant safety hazard.
[0007] Utility model patent CN205241142U discloses a partially variable track electric hoist. This device achieves partial track change by setting up a track and an electric trolley, which allows the movable hoist track to translate. However, the device has a complex structure and the track angle is not variable. Utility model patent CN219669994U discloses an adjustable-angle track for an electric hoist. This device drives a movable frame through the telescopic end of an electro-hydraulic actuator. A straight track and a curved track are set in the movable frame to achieve track change. However, the track change method of this device is not flexible enough, and it limits the expansion of the operating space of a single hoist. Utility Model Content
[0008] The purpose of this utility model application is to address the shortcomings of the aforementioned technology by providing a multi-channel rotating operating platform for hoists. This platform enables the connection of one movable hoist track with multiple fixed hoist tracks. When space constraints within a building prevent the installation of a single-beam suspended crane in a particular work scenario, this operating platform can expand the operating range of a single hoist, solving the problem of limited operating range for a single hoist, avoiding the simultaneous installation of multiple hoists within the building, improving work efficiency, and reducing safety hazards.
[0009] To achieve the above objectives, the multi-pass rotating operating platform for hoists provided by this utility model adopts the following technical solution:
[0010] A multi-channel rotating operating platform for hoists is characterized by comprising a rotating base, which is mounted on a fixed base via a main shaft. The rotating base has a movable hoist track, and at least one fixed hoist track circumferentially arranged on the outer side of the rotating base to cooperate with the movable hoist track. A drive mechanism for rotating the rotating base is located on the outer side of the fixed base. By adopting this technical solution, the movable hoist track can rotate under the drive of the rotating base and connect with any one of the fixed hoist tracks. When the movable hoist track connects with one of the fixed hoist tracks, the hoist can move on both the fixed and movable hoist tracks, expanding the operating range of a single hoist.
[0011] Preferably, a bearing is provided within the recessed space of the fixed base, and the bearing cooperates with the spindle. Adopting the above technical solution facilitates the rotation of the spindle.
[0012] Preferably, both ends of the movable hoist track are provided with stops for limiting the hoist's movement. By adopting the above technical solution, when the movable hoist track is connected to the fixed hoist track, the stops at the connection point are open, allowing the hoist to move linearly on both tracks; when the movable hoist track is not connected to the fixed hoist track, the stops are closed, preventing the hoist from moving and slipping off the movable hoist track.
[0013] Furthermore, the stop is movably positioned on the outer side of the rotating base above both ends of the movable hoist track. By adopting the above technical solution, the stop is a gravity-type movable stop. When the movable hoist track is connected to the fixed hoist track, the stop can be lifted by the fixed hoist track; when the movable hoist track is not connected to the fixed hoist track, the stop falls due to gravity.
[0014] Preferably, the top elevation of the movable hoist track is the same as that of the fixed hoist track. By adopting the above technical solution, it is beneficial for the hoist to move smoothly between the movable hoist track and the fixed hoist track.
[0015] Preferably, the drive mechanism is equipped with a gear, and the rotating base is equipped with a rack that meshes with the gear. Power is transmitted between the drive mechanism and the rotating base through the gear-rack engagement. By adopting the above technical solution, the power transmission between the drive mechanism and the fixed base is smoother and less prone to slippage.
[0016] Preferably, the spindle and the rotating base are fixedly connected. By adopting the above technical solution, the connection between the rotating base and the spindle is stable and easy to install.
[0017] Preferably, the rotating base and the movable hoist track are fixedly connected. By adopting the above technical solution, the connection between the rotating base and the movable hoist track is stable and the construction is simple.
[0018] Preferably, the drive mechanism and the fixed base are fixedly connected. By adopting the above technical solution, the connection between the drive mechanism and the fixed base is stable and the construction is simple.
[0019] Preferably, the fixed base is installed below the building's structural beam and is fixedly connected to the beam. By adopting the above technical solution, the connection between the fixed base and the building is more stable and installation is more convenient.
[0020] Through in-depth research, the applicant discovered the following technical bias in existing track-changing technologies: the industry generally believes that the hoist track system should maintain a fixed topology, and any track change should be achieved by increasing the number of hoists rather than modifying the track system itself. This patent breaks this technical bias and enables the movable hoist track to connect with multiple fixed hoist tracks.
[0021] The beneficial effects of this utility model are as follows: by setting a movable hoist track on the rotating base, the rotation of the rotating base drives the movable hoist track to connect with the fixed hoist track, enabling one hoist to run on multiple tracks, thus expanding the operating range of a single hoist; when the interior space of a building is limited and a single-beam suspended crane cannot be installed, this operating platform can expand the operating range of a single hoist, eliminating the need for multiple hoists and improving economic efficiency; it avoids the use of multiple hoist transfer devices, improving work efficiency and reducing safety risks.
[0022] Compared with the prior art, this utility model has the following advantages:
[0023] 1. Compared with single-girder suspended cranes, this utility model has a simpler structure and requires less interior space in the building;
[0024] 2. The movable hoist track can connect with multiple fixed tracks set around the outer circumference of the rotating base, making the hoist track changing angle flexible and the operating range wider. Attached Figure Description

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.
[0030] like Figure 1 , Figure 2 As shown, the multi-channel rotating platform for hoists of this utility model includes a rotating base 1, which is fixedly installed below the building's civil engineering beam 10. In this embodiment, a bolt connection is used. A bearing 2 and a main shaft 3 that mates with the bearing are provided in the recessed space of the fixed base 1. The shoulder diameter of the main shaft 3 is slightly larger than the inner ring diameter of the bearing 2. The main shaft 3 is fixedly connected to the rotating base 5, specifically, the main shaft 3 and the rotating base 5 are connected by a pin. The rotating base 5 is disc-shaped, and a movable hoist track 7 is welded to the bottom of the rotating base 5. The length of the movable hoist track 7 is the same as the diameter of the rotating base 5. After installation, the two ends of the movable hoist track 7 are flush with the edges of the rotating base 5. The fixed base 1 is flush with the outside of a drive mechanism 4 that drives the rotating base 5 to rotate. The drive mechanism 4 is welded to the outside of the fixed base 1. At least one fixed hoist rail 8 is provided circumferentially on the outside of the rotating base 5, which connects to the movable hoist rail 7. Each fixed hoist rail 8 is fixedly installed below the building's civil engineering beam 10, specifically by welding the fixed hoist rail 8 to the embedded steel plate of the building's civil engineering beam 10. After installation, the end of the fixed hoist rail 8 is located at the outer edge of the rotating base 5. When the movable hoist rail 7 connects with any one of the fixed hoist rails 8, the lifting hoist 9 can move on both the movable hoist rail 7 and the fixed hoist rail 8. The movable hoist rail 7 can rotate under the drive of the rotating base 5 and connect with any one of the fixed hoist rails 8. When the movable hoist rail 7 connects with one of the fixed hoist rails 8, the lifting hoist 9 can move on both the fixed hoist rail 8 and the movable hoist rail 7, expanding the operating range of a single lifting hoist.
[0031] To further improve the smoothness of power transmission in the drive mechanism 4, a gear is provided on the drive mechanism 4, and a rack that meshes with the gear is provided on the rotating base 5. Power is transmitted between the drive mechanism 4 and the rotating base 5 through the meshing of the gear and rack.
[0032] Both ends of the movable hoist track 7 are equipped with stops 6 for limiting the movement of the hoist 9. When the movable hoist track 7 is connected to the fixed hoist track 8, the stops 6 at the connection point are open, allowing the hoist 9 to move on both tracks. When the movable hoist track 7 and the fixed hoist track 8 are not connected, the stops 6 are closed, preventing the hoist 9 from moving. In this embodiment, the stops 6 are gravity-type movable stops, hinged to the outer side of the rotating base 5 above both ends of the movable hoist track 7, allowing them to rotate on a plane perpendicular to the radius of the rotating base 5. When the movable hoist track 7 is connected to the fixed hoist track 8, the stops 6 can be lifted by the fixed hoist track 8. When the movable hoist track 7 and the fixed hoist track 8 are not connected, the stops 6 fall due to gravity, limiting the movement of the hoist 9 and preventing it from slipping off the movable hoist track 7.
[0033] The movable hoist rail 7 and the fixed hoist rail 8 have the same rail top elevation. During the installation of the fixed hoist rail 8, first rotate the movable hoist rail 7 to the connection position, then align the fixed hoist rail 8 with the movable hoist rail 7 in the connection direction, keeping the rail top elevation consistent. Maintaining this position, weld the fixed hoist rail 8 to the embedded steel plate of the building's civil engineering beam 10. Repeat the above steps for the installation of each fixed hoist rail 8. After all the fixed hoist rails 8 are installed, the lifting hoist 9 can move between the movable hoist rail 7 and the fixed hoist rail 8.
[0034] The implementation principle of the electric hoist track shifting platform device in this application embodiment is as follows: A multi-pass rotating operating platform for hoists is set up inside the building. The hoist 9 is located on any track to carry out hoisting operations. When the hoist 9 needs to move, the rotating base 5 is driven to rotate by the drive mechanism 4, thereby driving the movable hoist track 7 to rotate synchronously. When the movable hoist track 7 rotates to connect with the fixed hoist track 8 where the hoist 9 is located, the stop 6 is lifted by the fixed hoist track 8, and the hoist 9 can move from the fixed hoist track 8 to the movable hoist track 7. Subsequently, the movable hoist track 7 continues to rotate. When the movable hoist track 7 is not connected with the fixed hoist track 8, the stop 6 falls due to gravity, limiting the range of movement of the hoist 9 on the movable hoist track 7 and preventing the hoist 9 from slipping. When the movable hoist track 7 connects with another fixed hoist track 8, the stop 6 is lifted by the fixed hoist track 8, and the hoist 9 can move from the movable hoist track 7 to the fixed hoist track 8. Through the above process, the hoist 9 can move between the movable hoist track 7 and each fixed hoist track 8.
[0035] Compared with the utility model patent with announcement number CN205241142U, this application creatively uses a rotating base as the track switching hub instead of a simple track translation. This structure brings at least two unexpected effects: (1) There is no need to set up a track and electric trolley for the movement of the hoist track, and the track changing system structure is simpler; (2) Multiple fixed hoist tracks are set on the outer circumference of the rotating base, which can change the angle and direction of the hoist.
[0036] Compared with the utility model patent with announcement number CN219669994U, the variable track structure provided in this application has more flexible direction and a wider operating range for the hoist.
[0037] Finally, it should be noted that the above content is a further detailed description of the utility model in conjunction with specific embodiments. It should not be considered that the specific implementation of the utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, any simple substitutions made without departing from the concept of this utility model should be considered to fall within the protection scope of this utility model.
