Description

Technical Field

[0001] The invention relates to a fixed rotary hoist. Background Art

[0002] An elevator refers to a mechanical device that can drive materials to rise, such as a winch, a crane, etc. The rotary elevator in this application refers to a device that can drive materials to move along its circumferential direction first and then lift them up. It is commonly used in the transportation of production materials. It usually includes a base, a shell, a hydraulic pump station and a hopper. The base and the shell are rotatably matched, the hopper is slidably set on the shell, and the hopper is connected to the hydraulic pump station by transmission. The hopper is driven to move by the hydraulic pump station, which can lift materials with larger weight levels. However, when it comes to materials with lower weight levels such as coatings, there are potential pollution and maintenance difficulties. As the years of use increase, this risk becomes increasingly prominent. In addition, the overall setting occupies a large space, resulting in relatively high production, commissioning and after-sales maintenance costs, which is not conducive to cost reduction for all parties. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the present invention provides a fixed rotary elevator that is suitable for materials of lower weight level, has less maintenance difficulty, lower cost, and has no potential pollution.

[0004] To achieve the above-mentioned purpose, the present invention provides a fixed rotary elevator, comprising a shell, a base, a hopper, and a first motor and a second motor arranged on one side of the shell, the shell and the base are rotatably matched, a long groove for guiding the sliding of the hopper is provided on the shell, the shell is vertically extended in a columnar shape, a first transmission chain, a first transmission wheel and a second transmission wheel are provided in the shell, the hopper includes a transmission part extending into the shell through the long groove, and the upper and lower ends of the transmission part are respectively connected to the two ends of the first transmission chain, the first transmission wheel and the second transmission wheel are respectively arranged at the upper and lower ends of the shell, and the second transmission wheel is in transmission cooperation with the first motor, the first transmission chain surrounds the first transmission wheel and the second transmission wheel and meshes with the two, and the second motor is in transmission cooperation with the base.

[0005] The advantages of adopting the above technical solution are: by setting up a shell, a base, a hopper, a first motor and a second motor, the first motor is used as the power, and cooperates with the first transmission wheel and the second magnetic power at the upper and lower sides of the shell, and the first transmission chain that surrounds and engages the first transmission wheel and the second transmission wheel to drive the hopper to extend into the shell to move, so that the hopper can slide along the long groove on the shell; the second motor is used as the power, and cooperates with the shell and the base to form a rotational coordination between the two, so that the hydraulic pump station is replaced by the motor, the overall structure is relatively simple, and the maintenance difficulty and cost are correspondingly reduced, which is more suitable for materials with lower weight levels.

[0006] The present invention can be further configured as follows: a fall arrester is provided between the shell and the transmission part, the fall arrester includes a limit fork located on the transmission part and a rack fixed in the shell, the rack is vertically extended, the limit fork can be elastically swung to engage with the rack, one end of the first transmission chain is connected to the limit fork, and the first transmission chain can cause the limit fork to swing in a direction away from the rack.

This allows the limit fork to be pulled by the first transmission chain when the hopper and the first transmission chain cooperate normally, and when the first transmission chain is loose, that is, when the fall arrester may fall, the limit fork loses the pull, and it will swing elastically and engage with the rack, forming a limit on the hopper, thereby achieving an anti-fall effect.
