Description

Technical Field

[0001] This utility model belongs to the field of winch technology, specifically relating to a slack rope limiting and anti-detachment device for lime kilns. Background Technology

[0002] A winch converts electrical energy into mechanical energy via an electric motor. The motor's rotor outputs energy, which is then reduced in speed via a V-belt, shaft, and gears before driving the drum. The drum winds a wire rope, and through a pulley system, the crane hook lifts or lowers the load, converting mechanical energy into mechanical work to complete the vertical transport and loading / unloading of the load. Winches commonly used in construction can be divided into two types: high-speed winches and low-speed winches. High-speed winches are mainly used for vertical and horizontal transport and piling operations. Low-speed winches are mainly used for structural hoisting, cold drawing of reinforcing bars, and other similar operations. The traction force of commonly used electric winches is generally 10~100kN.

[0003] The current winch slack rope limit device is greatly affected by external forces, such as when the wire rope swings or the equipment vibrates. Without a protective device, the limit protection device may fail, causing the slack rope limit device to misjudge and lead to machine shutdown. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a slack rope limiting and anti-detachment device for lime kilns, which features good slack rope limiting effect and prevents accidental triggering.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slack rope limiting and anti-detachment device for a lime kiln, comprising a base plate, a winch body is provided on one side of the upper end of the base plate, a drum is provided on one side of the winch body, a drum is wound around the surface of the drum, a limiting bracket is fixed on one side of the base plate corresponding to the wire rope, a slack rope limiting component is installed on the upper end of the limiting bracket, and a power cord is connected to one side of the slack rope limiting component.

[0006] Preferably, the slack rope limiting assembly includes a positioning seat, a positioning seat is fixed at the upper end of the bottom plate near the limiting bracket, a limiting seat is provided at the upper end of the positioning seat, a movable groove is opened inside the limiting seat, guide rods are symmetrically fixed at the upper end of the limiting seat, a limiting spring is sleeved on the surface of the guide rod, a limiting plate is fixed at the top end of the guide rod, and an emergency stop switch is provided at the upper end of the limiting bracket corresponding to the power line.

[0007] Preferably, the emergency stop switch is electrically connected to the power supply line, and an extension plate is fixed to the emergency stop switch on one side of the limiting plate.

[0008] Preferably, the inner wall surface of the positioning seat is provided with anti-slip texture, and the surface of the limiting seat is bonded with a damping pad.

[0009] Preferably, the upper ends of the positioning seat are provided with limit grooves on both sides corresponding to the wire rope.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention, by setting a slack rope limiting component, allows the wire rope to move within the movable groove when it becomes loose, reducing the amplitude of its sway. At this time, the limiting spring pushes the limiting seat downwards, inserting it into the positioning seat and reducing the exposed length of the movable groove, thus decreasing the amplitude of the wire rope's movement. When the wire rope is re-tensioned after vibration, the limiting seat immediately moves upwards, causing the limiting spring to rebound. In this case, the limiting plate will not contact the emergency stop switch, and the winch body remains operational. When the wire rope cannot be tensioned again, the limiting seat inserts into the positioning seat, and the limiting plate presses the emergency stop switch, allowing the winch body to receive an emergency stop signal and cease operation.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 The present invention provides the following technical solution: a slack rope limiting and anti-detachment device for lime kilns, comprising a base plate 4, a winch body 1 is provided on one side of the upper end of the base plate 4, a drum 3 is provided on one side of the winch body 1, a drum 3 is wound around the surface of the drum 3, a limiting bracket 6 is fixed on one side of the base plate 4 corresponding to the wire rope 2, a slack rope limiting component 5 is installed on the upper end of the limiting bracket 6, and a power cord 7 is connected to one side of the slack rope limiting component 5.

[0015] Specifically, the slack rope limiting assembly 5 includes a positioning seat 55. The positioning seat 55 is fixed at the upper end of the base plate 4 near the limiting bracket 6. A limiting seat 56 is provided at the upper end of the positioning seat 55. An movable groove 57 is opened inside the limiting seat 56. A guide rod 53 is symmetrically fixed at the upper end of the limiting seat 56. A limiting spring 54 is sleeved on the surface of the guide rod 53. A limiting plate 52 is fixed at the top of the guide rod 53. An emergency stop switch 51 is provided at the upper end of the limiting bracket 6 corresponding to the power line 7.

[0016] By adopting the above technical solution, if the wire rope 2 becomes loose, it will move within the movable groove 57 and reduce its swaying amplitude. At this time, the limit spring 54 will push the limit seat 56 downward, and the limit seat 56 will insert into the positioning seat 55, reducing the exposed length of the movable groove 57, thereby reducing the movement amplitude of the wire rope 2. When the wire rope 2 is re-tightened after vibration, the limit seat 56 will immediately move upward and cause the limit spring 54 to rebound. At this time, the limit plate 52 will not contact the emergency stop switch 51, and the winch body 1 will remain in working condition. However, when the loose wire rope 2 cannot be tightened again, it indicates that the trolley is in a dangerous situation. At this time, the limit seat 56 will be inserted into the positioning seat 55 under the continuous force of the limit spring 54, and the wire rope 2 will be stuck in the limit groove inside the positioning seat 55. The limit plate 52 will press the emergency stop switch 51, allowing the winch body 1 to receive an emergency stop signal and stop working, thus protecting the trolley and effectively avoiding safety accidents caused by loose rope.

[0017] Specifically, the emergency stop switch 51 is electrically connected to the power cord 7, and an extension plate is fixed to the emergency stop switch 51 on one side of the limit plate 52.

[0018] By adopting the above technical solution, the stability and accuracy of the limit plate 52 pressing the emergency stop switch 51 during use are guaranteed.

[0019] Specifically, the inner wall surface of the positioning seat 55 is provided with anti-slip texture, and the surface of the limiting seat 56 is bonded with a damping pad.

[0020] By adopting the above technical solution, the downward movement speed of the limit seat 56 is reduced, preventing the limit seat 56 from moving too much when the wire rope 2 sways slightly.

[0021] Specifically, limit grooves are provided on both sides of the upper end of the positioning seat 55 corresponding to the steel wire rope 2.

[0022] By adopting the above technical solution, it is ensured that when the limiting seat 56 is inserted into the positioning seat 55, it can press the wire rope 2 and assist the wire rope 2 in being tightened.

[0023] The working principle and usage process of this utility model are as follows: When this utility model is in use, during the operation of the winch body 1, the taut wire rope 2 passes through the inside of the limiting seat 56 and is installed on one side of the trolley. At this time, the wire rope 2 is inside the limiting seat 56 and is pushed up, so that the limiting spring 54 is compressed. If the wire rope 2 becomes loose, the wire rope 2 moves inside the movable groove 57 and reduces the amplitude of shaking. At this time, the limiting spring 54 will push the limiting seat 56 to move down. The limiting seat 56 is inserted into the positioning seat 55 and reduces the exposed length of the movable groove 57, thereby reducing the amplitude of movement of the wire rope 2. When the wire rope 2 is re-taut after vibration, the limiting seat 56 immediately moves up and causes the limiting spring 54 to rebound. At this time, the limiting plate 52 will not contact the emergency stop switch 51, and the winch body 1 remains in working state. When the loose wire rope 2 can no longer be tightened, it indicates that the trolley is in a dangerous situation. At this time, the limit seat 56 is inserted into the positioning seat 55 under the continuous force of the limit spring 54, and the wire rope 2 is stuck in the limit groove inside the positioning seat 55. The limit plate 52 presses the emergency stop switch 51, so that the winch body 1 can receive the emergency stop signal and stop working, thereby protecting the trolley and effectively avoiding safety accidents caused by loose rope.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
