Description

Technical Field

[0001] This utility model relates to the field of crane equipment technology, and in particular to a crane drum anti-derailment device. Background Technology

[0002] Cranes are widely used in industrial production, construction and other fields, and their drums are key components for winding and unwinding wire ropes.

[0003] During long-term use, due to various complex working conditions, such as the swaying of the lifted heavy objects, changes in drum speed, and wear of the wire rope, the wire rope is prone to coming off the drum.

[0004] Once the rope comes off, it will not only affect the normal operation of the crane, but may also cause safety accidents in severe cases, resulting in personal injury and property damage. Some existing anti-rope devices have complex structures, are inconvenient to install and maintain, and their anti-rope effect is not ideal, which cannot meet the actual use needs.

[0005] Therefore, this utility model proposes a crane drum anti-rope slippage device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crane drum anti-derailment device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a crane drum anti-derailment device, comprising:

[0008] A drum assembly consists of two baffles and a drum body. The drum body is disposed between the two baffles. The baffles are provided with movable holes. Limiting plates are provided on the sides of the two baffles that are far apart from each other. There are two limiting plates in total, and the two limiting plates are respectively disposed at both ends of the movable holes. A lifting rod is provided between the two limiting plates.

[0009] The anti-rope detachment assembly consists of a lifting sleeve, a connecting rod, and a sleeve that are slidably connected to the lifting rod. The connecting rod is disposed between the two lifting sleeves, and the sleeve is sleeved on the connecting rod. A limit guard plate is provided on one side of the sleeve located in the cylinder.

[0010] The warning assembly consists of a voltmeter mechanism located on the side of the baffle away from the cylinder and a buzzer alarm. The buzzer alarm is located on the voltmeter mechanism. A power connection post is provided at the end of the lifting sleeve near the voltmeter mechanism, and a resistance wire electrically connected to the voltmeter mechanism is wound on the power connection post.

[0011] Furthermore, there are four anti-slip rope components, which are arranged in a ring, and the included angle between two adjacent anti-slip rope components is equal.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: There are four anti-slip rope components, which are evenly distributed in a ring and the included angle between two adjacent components is equal. This layout design greatly improves the overall stability of the equipment. No matter which direction the force is applied, it can be evenly distributed, effectively preventing items from falling off. It greatly enhances the applicability of the equipment in complex environments and ensures safety and reliability during use.

[0013] Furthermore, the limiting guard plate has an arc-shaped structure, and the arc of the limiting guard plate is adapted to the arc of the cylinder.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: The limiting guard plate adopts an arc-shaped structure, and its curvature is perfectly matched with the cylinder body and fits tightly. It can accurately limit the displacement of internal objects, avoid shaking and collision of items, effectively protect the internal structure of the cylinder body and the placed items, and greatly reduce the risk of damage caused by the displacement of items during transportation and use, ensure stable operation of the equipment, and extend the service life of the equipment and items.

[0015] Furthermore, the cylinder body is provided with limiting grooves, and a total of multiple limiting grooves are provided, with the distance between two adjacent limiting grooves being equal.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: opening multiple equally spaced limiting grooves on the cylinder has significant advantages. These limiting grooves can accurately position various accessories, facilitate installation and debugging, and greatly improve assembly efficiency. During equipment operation, they can effectively fix internal components, prevent their displacement, and ensure stable operation of the equipment. Moreover, the equal spacing facilitates standardized production, reduces costs, and improves overall production efficiency.

[0017] Furthermore, a spring is fitted onto the lifting rod, and the two ends of the spring are in contact with the limiting plate and the top of the lifting sleeve, respectively.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the spring sleeved on the lifting rod has its two ends in contact with the limiting plate and the top of the lifting sleeve, respectively. In actual use, it can drive the limiting plate to move downward according to the winding and unwinding of the rope on the drum, so that the limiting plate always keeps in contact with the rope on the drum, thereby improving the safety and convenience of operation.

[0019] Furthermore, the output terminal of the resistance wire is electrically connected to the input terminal of the voltmeter mechanism, and the output terminal of the voltmeter mechanism is electrically connected to the input terminal of the buzzer alarm.

[0020] The beneficial effects of adopting the above-mentioned further solution are as follows: the electrical connection between the resistance wire, the voltmeter mechanism, and the buzzer alarm is significant. When the environment of the resistance wire changes, its resistance value changes, resulting in voltage changes. The voltmeter mechanism can keenly capture and transmit the signal. Once the voltage exceeds the preset range, the buzzer alarm will respond immediately and issue an alarm in a timely manner. This circuit connection can accurately monitor and quickly warn, effectively ensuring equipment safety and avoiding malfunctions or dangers caused by abnormalities.

[0021] Furthermore, each of the two baffles, located at opposite ends, is provided with a connecting shaft that passes through the voltmeter mechanism.

[0022] The beneficial effects of adopting the above-mentioned further solution are: both ends of the two baffles that are far apart from each other are provided with connecting shafts that pass through the voltmeter mechanism. The connecting shafts not only provide stable support for the baffles and ensure the stable operation of the drum assembly, but also cleverly establish the connection between the baffles and the voltmeter mechanism. During the operation of the drum, the voltage-related data can be fed back in real time as it rotates, allowing the voltmeter mechanism to monitor accurately and ensure the safe and efficient operation of the equipment.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] In this invention, the electric connection between the resistance wire, the voltmeter mechanism, and the buzzer alarm is highly effective. When the environment of the resistance wire changes, its resistance value changes, resulting in voltage changes. The voltmeter mechanism can keenly capture and transmit the signal. Once the voltage exceeds the preset range, the buzzer alarm will respond immediately and issue an alarm in a timely manner. This circuit connection can accurately monitor and quickly warn, effectively ensuring equipment safety and avoiding malfunctions or dangers caused by abnormalities. Attached Figure Description

[0034] like Figure 1-4 As shown, this utility model provides a technical solution: a crane drum anti-derailment device, comprising:

[0035] The drum assembly 1 consists of two baffles 11 and a drum body 12. The drum body 12 is disposed between the two baffles 11. The baffles 11 are provided with movable holes 111. Limiting plates 14 are provided on the side of the two baffles 11 that are far apart from each other. There are two limiting plates 14 in total, and the two limiting plates 14 are respectively disposed at both ends of the movable holes 111. A lifting rod 141 is disposed between the two limiting plates 14.

[0036] The anti-rope detachment assembly 2 consists of a lifting sleeve 24, a connecting rod 23, and a sleeve 22 that are slidably connected to the lifting rod 141. The connecting rod 23 is located between the two lifting sleeves 24, and the sleeve 22 is sleeved on the connecting rod 23. A limit guard plate 21 is provided on one side of the sleeve 22 located in the cylinder 12.

[0037] Warning component 3 consists of a voltmeter mechanism 31 located on the side of the baffle 11 away from the cylinder 12 and a buzzer alarm 32. The buzzer alarm 32 is located on the voltmeter mechanism 31. A power connection post 33 is provided at the end of the lifting sleeve 24 near the voltmeter mechanism 31. A resistance wire 34 electrically connected to the voltmeter mechanism 31 is wound around the power connection post 33.

[0038] There are four anti-detachment rope components 2, which are arranged in a ring. The included angle between any two adjacent anti-detachment rope components 2 is equal. This layout design greatly improves the overall stability of the equipment. No matter which direction the force is applied, it can be evenly distributed, effectively preventing items from falling off. This greatly enhances the applicability of the equipment in complex environments and ensures safety and reliability during use.

[0039] The limiting guard plate 21 has an arc-shaped structure, and the arc of the limiting guard plate 21 is adapted to the arc of the cylinder 12. The limiting guard plate 21 adopts an arc-shaped structure, and its arc perfectly matches the cylinder 12, fitting tightly. It can accurately limit the displacement of internal objects, avoid shaking and collision of items, and effectively protect the internal structure of the cylinder 12 and the placed items.

[0040] A spring 25 is fitted on the lifting rod 141. The two ends of the spring 25 are in contact with the top of the limiting plate 14 and the lifting sleeve 24, respectively.

[0041] The output terminal of the resistance wire 34 is electrically connected to the input terminal of the voltmeter mechanism 31, and the output terminal of the voltmeter mechanism 31 is electrically connected to the input terminal of the buzzer alarm 32. The electrical connection between the resistance wire 34, the voltmeter mechanism 31, and the buzzer alarm 32 has a significant effect.

During drum operation, it can provide real-time feedback of voltage-related data as it rotates, allowing the voltmeter mechanism 31 to monitor accurately and ensure the safe and efficient operation of the equipment.
