Description

A flat steel protection device for the rope winding of a well sinking winch Technical Field

[0001] This utility model relates to the technical field of vertical shaft operation equipment, and in particular to a flat steel protection device for the rope winding of a shaft sinking winch. Background Technology

[0002] During the winding and laying of wire ropes by the shaft sinking winch, due to the large force, as the shaft depth increases during the construction and hoisting operation, in order to prevent the wire ropes from biting, pressing, or unevenly arranging each time, a flat steel bar is placed every 300mm between each layer to separate the wire ropes.

[0003] However, in actual work, since the wire rope is wound from one end of the flat steel, the other end of the flat steel is prone to severe deformation under the force transmission of the wire rope, resulting in it tilting upwards. The deformed and tilted flat steel will scrape against the foundation frame of the well sinking winch, and the tail of the flat steel will scratch the wire rope. On the other hand, the severely deformed flat steel cannot be reused, which will lead to waste of materials and increase construction costs.

[0004] Therefore, there is an urgent need for a flat steel protection device for well sinking winches that can fix and position the flat steel to prevent it from warping, bending, and causing severe deformation. Summary of the Invention

[0005] The purpose of this invention is to provide a protective device for flat steel used in the winding of a well sinking winch. This device can fix and position the flat steel, prevent it from warping or bending and causing severe deformation, reduce the probability of damage during the winding of the wire rope, increase the reusability of the flat steel, and save construction costs.

[0006] The present invention adopts the following technical solution:

[0007] A protective device for flat steel entangled in a well sinking winch includes a fixed rope with multiple limiting plates spaced apart along its length. One end of the fixed rope is equipped with a tensioner. During operation, one end of the fixed rope is connected to the tensioner to form a closed loop structure, which is fitted over the flat steel on the well sinking winch. Adjusting the tensioner causes the fixed rope to tighten, making the limiting plates tightly adhere to the flat steel.

[0008] Preferably, the rope tensioner includes a positioning plate, one end of the fixing rope is connected to the positioning plate, a rope tensioning drum is rotatably mounted on the positioning plate, a ratchet is coaxially mounted on the rope tensioning drum, and ratchet teeth that mesh with the ratchet are provided on the positioning plate.

[0009] Preferably, the tensioning drum is provided with a hook.

[0010] Preferably, the end of the fixing rope away from the tensioning cylinder is provided with a loop.

[0011] Preferably, the end of the tensioning drum away from the ratchet is provided with an adjustment hole.

[0012] Preferably, two fixing ropes are provided.

[0013] Preferably, the limiting plate is adjustablely mounted on the fixing rope.

[0014] Preferably, the top of the limiting plate is provided with a sliding sleeve, and the fixing rope moves through the sliding sleeve.

[0015] Preferably, a rubber pad is provided at the bottom of the limiting plate.

[0016] Preferably, the positioning plate is provided with a connecting hole, and one end of the fixing rope is connected to the positioning plate through the connecting hole.

[0017] Compared with existing technologies, the advantages of this utility model are as follows: This utility model uses a fixed rope and a rope tensioner to form a ring structure, which is sleeved on one end of a flat steel bar. Then, adjusting the rope tensioner tightens the fixed rope, allowing the limiting plate to fit tightly against the flat steel bar, thus fixing one end of the flat steel bar. This effectively prevents the flat steel bar from deforming under the force transmitted by the wire rope, achieving the purpose of protecting the wire rope, extending the service life of the flat steel bar, and improving its reusability. The structure is simple, easy to use, and highly practical. Furthermore, the rope tensioner's ability to tighten and loosen the fixed rope allows for the use of various diameter well-drilling winch drums, expanding the applicability of this utility model and enhancing its practicality.

[0021] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0022] As shown in Figures 1 to 3, the present invention provides a protective device for flat steel wrapped in a drilling winch, comprising a fixed rope 1, which may be made of steel wire rope. Multiple limiting plates 2 are spaced apart along the length of the fixed rope 1. A tensioner is provided at one end of the fixed rope 1. During operation, one end of the fixed rope 1 passes through the bottom of the drilling winch drum 4 and connects to the tensioner to form a closed loop structure, which is then fitted onto the outside of the flat steel 3 on the drilling winch. Adjusting the tensioner tightens the fixed rope 1, causing the limiting plates 2 to adhere tightly to the flat steel 3. This achieves positioning of the end of the flat steel 3, preventing deformation of the flat steel 3 under the force transmission of the steel wire rope. This protects the steel wire rope, extends the service life of the flat steel 3, and increases its reusability.

[0023] Furthermore, in this embodiment, the rope tensioner includes a positioning plate 5 with a connecting hole 6. One end of the fixing rope 1 is connected to the positioning plate 5 through the connecting hole 6. Preferably, two fixing ropes 1 are provided, arranged parallel to each other at intervals, to improve the uniformity of force applied to the limiting plate 2, so that the limiting plate 2 fits tightly against the flat steel 3, improving the positioning effect of the limiting plate 2 on the flat steel 3. A rope tensioning drum 7 is rotatably mounted on the positioning plate 5, and a ratchet 8 is coaxially mounted on the rope tensioning drum 7. The positioning plate 5 is elastically provided with ratchet teeth 9 that mesh with the ratchet 8. The meshing of the ratchet 8 and ratchet teeth 9 can limit the rope tensioning drum 7, ensuring that the fixing rope 1 is tightly wound around the outside of the flat steel 3 after being wound by the rope tensioning drum 7. In addition, a hook 10 is provided on the rope tightening drum 7 to fix the free end of the rope 1, so as to facilitate the quick connection between the free end of the rope 1 and the rope tightening drum 7; preferably, a loop is provided on the end of the rope 1 away from the rope tightening drum 7, and the loop is made of high-strength metal; the loop is provided to facilitate the fastening of the rope to the hook 10, thereby improving the convenience of operation.

[0024] Furthermore, an adjustment hole 11 is provided at the end of the tightening drum 7 away from the ratchet 8, facilitating the insertion of tools to rotate the tightening drum 7 and complete the winding of the fixed rope 1. A longer tool can be used to increase torque and improve the ease of adjustment of the tightening drum 7. In addition, a limiting plate 2 is adjustablely mounted on the fixed rope 1. Specifically, a sliding sleeve 12 is provided at the top of the limiting plate 2, through which the fixed rope 1 moves. This adjustable mounting of the limiting plate 2 relative to the fixed rope 1 allows for flexible adjustment of its position according to the arrangement of the flat steel 3, ensuring that the limiting plate 2 adheres to the flat steel 3 and guarantees the desired action on the flat steel 3. Furthermore, a rubber pad is preferably provided at the bottom of the limiting plate 2 to increase the tightness of contact between the limiting plate 2 and the flat steel 3, while reducing wear between them.

[0025] In use, the present invention first passes one end of the fixing rope 1 through the bottom of the well sinker drum 4 and connects it with the tightening drum 7 to form a ring structure that is sleeved on the outside of the flat steel 3. Then, the position of the limiting plate 2 is adjusted according to the position of the flat steel 3. Finally, the tightening drum 7 is adjusted to wind the fixing rope 1 onto it, completing the tight winding of the fixing rope 1 on the outside of the flat steel 3, ensuring that the limiting plate 2 is tightly attached to the flat steel 3. After the wire rope of this layer is wound, the protective device can be removed.
