Description

Technical Field

[0001] The utility model relates to the technical field of suspension arms, in particular to a suspension arm mechanism. Background Art

[0002] A suspension arm is a mechanical device used for lifting and handling. It can improve work efficiency, reduce costs and improve safety. It is one of the common and important equipment in modern industrial production. The suspension arm can help workers lift and carry goods quickly and efficiently, saving manpower and time costs. It can operate at different heights and positions, improving the flexibility and efficiency of operations. The use of a suspension arm can reduce dependence on manpower, reduce the risk of personal injury, and ensure workplace safety. In short, the suspension arm plays an important role in industrial production.

[0003] Most of the suspension arms currently on the market have complex structures. In the later maintenance and upkeep, they will consume a lot of manpower and time of construction workers, increase the cost of use and maintenance, and waste a lot of time. Some suspension arms have fewer auxiliary components. When the suspension arm is working, external dust and small debris will enter the internal parts of the suspension arm, causing damage to the internal parts of the suspension arm, affecting subsequent use and even causing the suspension arm to collapse, which is very dangerous.

[0004] Therefore, there is an urgent need to provide a suspension arm mechanism to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is that most of the suspension arms currently on the market have complex structures, which will consume a lot of manpower and time of construction workers in the later maintenance and upkeep, increase the cost of use and maintenance and waste a lot of time. Some suspension arms have fewer auxiliary components. When the suspension arm is working, dust and small debris from the outside will enter the parts inside the suspension arm, causing damage to the parts inside the suspension arm, affecting the subsequent use and even causing the suspension arm to collapse, which is very dangerous.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a suspension arm mechanism, including a support column, a plurality of fixing screws are installed at the bottom of the support column, a limiting groove is provided on the outer wall of the support column, a toothed plate is fixedly connected inside the limiting groove, and a dust cover corresponding to the limiting groove is installed on the outer wall of the support column;

[0007] A fixing plate is fixedly connected to the outer wall of the support column near the top, and a protective cover and a steel cable winding assembly are respectively installed on the top of the fixing plate;

[0008] An extension arm is installed on the top of the support column, and a self-driven adjusting trolley is slidably connected to the inner wall of the extension arm. A steel rope is installed between the steel cable winding assembly and the self-driven adjusting trolley, and a hook is fixedly connected to one end of the steel rope away from the steel cable winding assembly. A fixed block is fixedly connected to one side of the self-driven adjusting trolley, and a limiting mechanism is arranged inside the fixed block.

[0009] The utility model is further configured as follows: the steel rope is installed between the steel rope winding assembly and the hook.

[0010] Through the above technical solution, when the self-driving adjusting trolley moves inside the extension arm, the cable winding assembly will also operate synchronously, so that the cable between the cable winding assembly and the hook will not break. When the self-driving adjusting trolley reaches the specified position, the cable winding assembly will start working, causing the hook under the self-driving adjusting trolley to drop, making it convenient for ground personnel to carry out subsequent work.

[0011] The utility model is further configured as follows: a limiting sliding groove corresponding to the self-driving regulating trolley is provided inside the extension arm.

[0012] Through the above technical solution, the limiting slide groove can effectively limit the movement trajectory of the self-driving adjustable trolley inside the extension arm, so that it can only move along the path of the limiting slide groove, which can effectively improve the stability of the movement of the self-driving adjustable trolley and the stability during subsequent lifting of goods.

[0013] The utility model is further configured as follows: the limiting mechanism includes a connecting strip rotatably connected to the inner walls on both sides of the fixed block, holes are opened inside the connecting strip, a hydraulic cylinder is installed inside the connecting strip, the output end of the hydraulic cylinder is fixedly connected to the limiting plate, and the end of the connecting strip is rotatably connected to a gear.

[0014] Through the above technical solution, when the hydraulic cylinder is not working, the limit plate connected to the hydraulic cylinder will not limit the rotation of the gear, and the gear can rotate freely. When the gear is needed to limit the movement of the self-driving adjusting trolley, it is only necessary to start the hydraulic cylinder, and the limit plate is driven to move toward the gear through the work of the hydraulic cylinder. The movement of the gear is limited by the engagement of the limit plate with the gear, thereby ensuring that the self-driving adjusting trolley can no longer be displaced, so that the entire mechanism can achieve the function of hovering.

[0015] The utility model is further configured as follows: the outer wall of the dust cover is provided with a sliding groove corresponding to the connecting strip.

[0016] Through the above technical solution, the slide groove will not affect the up and down movement of the connecting strip, and the dust cover can also effectively prevent external dust and debris from entering the interior of the dust cover, ensuring that the connecting strip can slide smoothly inside the dust cover.

[0017] The utility model is further configured as follows: the limit plate is meshed with the gear.

[0018] Through the above technical solution, when the mechanism needs to hover, the hydraulic cylinder connected to the limit plate can be started to make the limit plate engage with the gear, so that the gear cannot move. At this time, the entire mechanism will be stuck by the limit, so that the entire device can hover.

[0019] The utility model is further configured as follows: the gear is meshed with a toothed plate.

[0020] Through the above technical solution, the gear can move up and down on the tooth plate. When the self-driving adjusting trolley moves, it will also drive the limit mechanism to move. At this time, the connecting strip inside the limit mechanism can not only play a connecting role, but also play a load-bearing role. When the hovering function needs to be realized, the limit plate is needed to limit the movement of the gear. At this time, the gear can no longer move on the tooth plate, and the hovering function of the device can be realized.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. The utility model is designed with a dust cover, which can effectively prevent dust and debris in the external environment from entering the device, causing wear of the parts inside the device and affecting the operation of the internal parts, thereby ensuring that the device can operate normally;

[0023] 2. The utility model designs the connecting strip and the gear connected to the connecting strip. When the self-driving adjusting trolley moves, the self-driving adjusting trolley will also drive the connecting strip to move. The connecting strip not only plays a connecting role, but also helps to share part of the load, ensuring that the entire device will not collapse due to force problems;

[0024] 3. The utility model designs a hydraulic cylinder and a limit plate. When the device needs to hover, it only needs to start the hydraulic cylinder to make the limit plate connected to the hydraulic cylinder mesh with the gear in the limit mechanism, so that the gear can no longer move on the tooth plate. At this time, the entire mechanism cannot move, thereby realizing the hovering function. BRIEF DESCRIPTION OF THE DRAWINGS

The end of the steel rope 11 away from the steel rope winding assembly 8 is fixedly connected with a hook 12, and the steel rope 11 is installed between the steel rope winding assembly 8 and the hook 12. When the self-driven adjusting trolley 10 moves inside the extension arm 9, the steel rope winding assembly 8 will also operate synchronously so that the steel rope between the steel rope winding assembly 8 and the hook 12 will not break. When the self-driven adjusting trolley 10 reaches the specified position, the steel rope winding assembly 8 will start working, so that the hook 12 under the self-driven adjusting trolley 10 will drop, which is convenient for ground personnel to carry out subsequent work.
