Description

Technical Field

[0001] This utility model belongs to the field of copper smelting equipment maintenance, and specifically relates to a force-turning elbow type special guide device. Background Technology

[0002] Currently, there are significant operational difficulties and efficiency issues during the installation of inclined spiral shafts or long shaft equipment. Specifically, this is evident in the shaft reinstallation stage, particularly when installing to approximately one-third of the shaft's rear end. Because the shaft angle is difficult to naturally match the installation requirements, guide chains are often needed for auxiliary adjustment. However, in practice, the lack of dedicated fixed anchor points on the spiral cylinder surface forces maintenance personnel to repeatedly search for temporary anchoring positions and disassemble and reassemble guide chains multiple times, leading to complex procedures and inconvenience. This process not only significantly increases the workload of maintenance personnel but also greatly extends maintenance time. Statistics show that reinstalling a single spiral shaft or long shaft for its rear one-third section takes an average of approximately 1.5 hours. For equipment with two shafts, the cumulative time required to reinstall both shafts can reach approximately 3 hours, severely impacting maintenance efficiency, increasing equipment downtime, and adversely affecting overall production operations. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a force-operated elbow-type special guide device that is simple in structure, easy to use, and can effectively save maintenance time and manpower.

[0004] This utility model is achieved through the following technical solution: A force-turning elbow-type special guide device includes a guide head and a spiral cylinder; the guide head includes side stops, U-groove bearings, a fixed shaft, and a sleeve; the fixed shaft passes through the U-groove bearings and is fixedly connected to the side stops on both sides; the sleeve is fixedly connected to the bottom of the side stops; The spiral cylinder includes a spiral cylinder wall, a guide chain, guide chain hanging points, a steel wire rope, and steel wire rope hanging points; the guide chain hanging points and steel wire rope hanging points are fixed to the spiral cylinder wall; the guide chain is fixedly connected to the guide chain hanging points; one end of the steel wire rope is fixedly connected to the guide chain, and the other end passes through the U-groove bearing and is fixedly connected to the steel wire rope hanging points.

[0005] To further illustrate this invention, a baffle is also fixedly provided at the top of the sleeve. The baffle prevents the spiral shaft or long shaft from colliding with the guide head during installation, thus protecting the guide head.

[0006] Further explanation of this utility model: the guide head and the spiral cylinder are movably connected by a connector; the connector includes a nut I fixed to the outside of the side guards on both sides and a nut II on the sleeve, as well as bolts that match the nut I and nut II. The bolts pass through the nut I on the outside of the side guards and the nut II on the sleeve, thus achieving a movable connection between the side guards and the sleeve. This allows for selection of a sleeve of a matching size according to the diameter of the spiral shaft or the long shaft, making its use more flexible.

[0007] A guide head is fitted onto the head of the spiral shaft, and the top of the guide chain is attached to the guide chain hanging point on the spiral cylinder wall. The guide chain hook is connected to the wire rope, and the end of the wire rope is attached to the wire rope hanging point on the spiral cylinder wall. This allows the wire rope to pass through the U-groove bearing, tightening the guide chain to transmit force axially along the spiral shaft or long shaft, thereby pressing the entire spiral shaft or long shaft to move into the spiral cylinder.

[0008] The beneficial effects of this utility model are: This utility model has a simple structure and is easy to use, effectively saving maintenance time, especially the time spent on the rear third section of the screw shaft or long shaft during reassembly. Furthermore, the use of a guide chain and U-groove bearings effectively improves work efficiency and saves manpower. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings. Example

[0011] like Figure 1 and Figure 2 As shown, a force-turning elbow-type special guide device includes a guide head 1 and a spiral cylinder; the guide head includes a side stop 11, a U-groove bearing 12, a fixed shaft 13 and a sleeve 14; the fixed shaft 13 passes through the U-groove bearing 12 and is fixedly connected to the side stops 11 on both sides; the sleeve 14 is fixedly connected to the bottom of the side stops 11 by welding or other means. The spiral cylinder includes a spiral cylinder wall 2, a guide chain 3, a guide chain hanging point 4, a steel wire rope 5, and a steel wire rope hanging point 6; the guide chain hanging point 4 and the steel wire rope hanging point 6 are fixed on the spiral cylinder wall 2; the guide chain 3 is fixedly connected to the guide chain hanging point 4; one end of the steel wire rope 5 is fixedly connected to the guide chain 3, and the other end passes through the U-groove bearing 12 and is fixedly connected to the steel wire rope hanging point 6.

[0012] A guide head 1 is fitted onto the head of the spiral shaft. The top of the guide chain 3 is attached to the spiral cylinder wall 2 along the guide chain hanging point 4. The hook of the guide chain 3 is connected to the wire rope 5. The end of the wire rope 5 is attached to the wire rope hanging point 6 on the spiral cylinder wall 2, so that the wire rope 5 passes through the U-groove bearing 12, and the guide chain 3 is tightened to transmit the force axially along the spiral shaft or long shaft, thereby pressing the entire spiral shaft or long shaft to move into the spiral cylinder. Example

[0013] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that a baffle 15 is also fixedly provided on the top of the sleeve 14. The baffle 15 prevents the spiral shaft or long shaft from colliding with the guide head 1 during the installation process, thereby protecting the guide head 1. Example

[0014] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the guide head 1 and the spiral cylinder are movably connected by a connector; the connector includes a nut I7 fixed to the outside of the side blocks 11 on both sides and a nut II8 on the sleeve, as well as a bolt 9 used to match the nut I and the nut II.

[0015] The nut can be fixed to the side guard and the sleeve by welding. The nut I7 on the outside of the side guard 11 and the nut II8 on the sleeve are connected by bolt 9, so that the side guard 11 and the sleeve 14 can be movably connected. This allows the sleeve 14 to be selected according to the diameter of the helical shaft or the long shaft, making it more flexible to use.
