Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically to an unattended crane with material placement and loading functions. Background Technology

[0002] An unattended crane is a type of lifting equipment that integrates automation technology, sensors, control systems, and communication technology to achieve remote control or fully autonomous operation. It requires no direct on-site human intervention, instead completing material handling tasks through preset programs, remote commands, or intelligent algorithms. It is widely used in industrial manufacturing, logistics warehousing, ports, and other scenarios requiring efficient and safe operation. For example, in prior art 1 (Chinese patent application number CN202222416681.2, application date 2022-09-13), an unattended intelligent crane uses dual-output motors to synchronously drive two trolley traveling mechanisms, reducing deviation and improving the stability of crane operation. It also protects the transmission devices at the output ends of the dual-output motors, reducing the risk of scratches and damage during operation, and decreasing the probability of worker contact, thus reducing the occurrence of safety accidents.

[0003] While existing technologies can improve the operational stability and reliability of cranes, when conveying quartz sand, they essentially transport the material directly into the storage tank. However, this direct conveying method causes the quartz sand to scatter, resulting in dust and impurities being dispersed into the air, which can affect the health and safety of workers. This makes the technology impractical. Therefore, unattended cranes with material placement and loading functions have been proposed to effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an unattended crane with material feeding and loading functions to solve the problem mentioned in the background art that the current market directly transports quartz sand material to the inside of the storage tank. However, this direct transportation method causes the quartz sand material to scatter, resulting in dust and impurities being scattered in the air, which affects the health and safety of workers and has poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an unattended crane with material placement and loading functions, including a storage pool and a bridge frame installed above the storage pool. A transverse material placement trolley is slidably installed above the bridge frame, and a conveyor belt is installed above the transverse material placement trolley via a drive motor. The storage pool is located below the conveyor belt. A loading seat is provided on the left side of the storage pool, and a grab bucket is located above the loading seat. The grab bucket is located below the bridge frame. A conveying auger is rotatably installed inside the storage pool, and the left end of the conveying auger extends through into the interior of the loading seat. A control motor is connected to the output end of the conveying auger, and the control motor is located on the right side of the storage pool.

[0006] Preferably, a mounting shell is installed on the right side of the storage tank, and two mounting rods are rotatably mounted inside the mounting shell, with the inner ends of the two mounting rods being connected to a conveying auger rod through a first bevel gear set.

[0007] Preferably, the outer ends of the two mounting rods are connected to the output ends of two rotating shafts via a second bevel gear set, and the two rotating shafts are rotatably mounted inside the storage tank.

[0008] Preferably, the two rotating shafts are symmetrically arranged about the transverse centerline of the storage tank, and the two rotating shafts rotate in opposite directions.

[0009] Preferably, a row of rotating conveyor plates is installed on the outer sides of the two rotating shafts, and the two rows of rotating conveyor plates are arranged at equal intervals.

[0010] Preferably, the outer sides of the two rotating shafts are fixedly mounted with striking rods, and the upper sides of the two striking rods are correspondingly supported by force rods. The two force rods are fixedly mounted on the outer ends of the two steel air pipes, and the two steel air pipes are rotatably mounted on the inner wall of the storage tank. The two steel air pipes are connected to an external pump body through pipelines.

[0011] Preferably, a row of dust collection trays is installed at equal intervals on the outer surfaces of the two steel air pipes, and one end of two torsion springs is fixedly connected to the outer surfaces of the two steel air pipes, while the other end of the two torsion springs is fixedly connected to the inner wall of the storage tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This unmanned crane, equipped with material placement and loading functions, can transport quartz sand material through the drop port to the conveyor belt above the horizontal material placement trolley for material placement. Then, the drive motor is started to drive the conveyor belt to place the quartz sand material on its surface, so that the quartz sand material falls into the storage tank, which facilitates the subsequent loading of quartz sand material.

[0013] This unmanned crane, equipped with material feeding and loading functions, starts the control motor to drive the conveying auger after the quartz sand material falls into the storage tank. At the same time, the rotating conveying auger will transport the quartz sand material stored in the storage tank to the loading seat, and then the grab bucket can be used to load the quartz sand material.

[0014] This unattended crane, equipped with material feeding and conveying functions, simultaneously controls the motor to drive the conveying auger to transport quartz sand. At the same time, the output end of the conveying auger drives two mounting rods to rotate inside the mounting housing via the first bevel gear set. Then, the two rotating mounting rods drive two rotating shafts to rotate via the second bevel gear set. Subsequently, the two rotating shafts drive two rows of rotating conveyor plates to aggregate the quartz sand material inside the storage tank, thus better assisting the conveying auger in material conveying.

[0015] This unattended crane, equipped with material feeding and conveying functions, uses two rotating shafts to drive two rows of rotating conveyor plates to gather materials. At the same time, the beaters installed at the output ends of the two rotating shafts squeeze and rotate the force rods installed at the outer ends of the two steel air pipes. Then, the two force rods drive the two steel air pipes to drive the two rows of dust collection discs to swing and absorb the dust and impurities generated by the falling quartz sand material. This expands the absorption range of the two rows of dust collection discs for dust and impurities, thus purifying the working environment.

[0016] This unattended crane, which has both material feeding and conveying functions, allows the torsion spring to elastically reset the position of the rotated steel air pipe after the striking bar and the force bar have no actual contact. This helps to elastically reset the position of the row of swinging dust collection discs, thus improving the efficiency of conveying quartz sand materials in the later stages.

[0019] 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.

[0020] This utility model provides the following technical solution: an unattended crane with material placement and loading functions: Example 1: To address the problem that existing methods of directly conveying quartz sand into the storage tank 1 result in the quartz sand scattering, causing dust and impurities to disperse into the air and affecting the health and safety of workers, thus lacking practicality, the following solution is disclosed: Beating rods 14 are fixedly installed on the outer sides of two rotating shafts 8, and force-bearing rods 13 are correspondingly installed above the two beating rods 14. The two force-bearing rods 13 are fixedly installed on the outer ends of two steel air pipes 11, and the two steel air pipes 11 are rotatably installed on the inner wall of the storage tank 1. Two steel air pipes 11 are connected to an external pump body via pipelines. During the process of the two rotating shafts 8 driving two rows of rotating conveyor plates 9 to gather material, the striking rods 14 installed at the output ends of the two rotating shafts 8 simultaneously squeeze and rotate the force-bearing rods 13 installed at the outer ends of the two steel air pipes 11. At this time, the two force-bearing rods 13 simultaneously drive the two steel air pipes 11 to drive the two rows of dust collection discs 12 to oscillate and absorb the dust and impurities generated by the falling quartz sand material. This expands the absorption range of the two rows of dust collection discs 12 for dust and impurities, purifying the working environment. Figure 3 and Figure 4 As shown.

[0021] Two steel air pipes 11 are equidistantly connected on their outer surfaces with a row of dust collection discs 12. Two torsion springs 15 are fixedly connected to one end of each pipe, and the other end of each spring is fixedly connected to the inner wall of the storage tank 1. When the striking rod 14 and the force-bearing rod 13 are not in actual contact, the torsion springs 15 will use their own elastic force to elastically reset the position of the rotated steel air pipes 11, thus assisting in the elastic reset of the row of swinging dust collection discs 12. This better assists in the subsequent conveying efficiency of the quartz sand material. Figure 6 As shown.

[0022] Example 2, unlike Example 1, allows for the distribution and guiding of quartz sand material to achieve the feeding effect, improving the conveying efficiency of the crane. The following is disclosed: The system includes a storage tank 1 and a cable tray 2 installed above it. A transverse material distribution trolley 3 is slidably mounted above the cable tray 2, and a conveyor belt 4 is mounted above the transverse material distribution trolley 3 via a drive motor. The storage tank 1 is located below the conveyor belt 4. While the crane is conveying quartz sand, the quartz sand can be fed through the discharge port to the conveyor belt 4 above the transverse material distribution trolley 3 for distribution. The drive motor is then activated to drive the conveyor belt 4 to distribute the quartz sand onto its surface, causing it to fall into the storage tank 1 for later auxiliary material feeding. Figure 1 and Figure 2 As shown.

[0023] A feeding seat 6 is located on the left side of the storage tank 1, and a grab bucket 5 is positioned above the feeding seat 6, below the bridge frame 2. A conveying auger 7 is rotatably installed inside the storage tank 1, with its left end extending through the feeding seat 6. A control motor is connected to the output end of the conveying auger 7, located on the right side of the storage tank 1. When quartz sand falls into the storage tank 1, the control motor is activated to drive the conveying auger 7. The rotating conveying auger 7 simultaneously conveys the quartz sand stored in the storage tank 1, transporting it to the feeding seat 6. The grab bucket 5 then feeds the quartz sand into the storage tank 1. Figures 1-3 As shown.

[0024] A mounting shell 10 is installed on the right side of the storage tank 1, and two mounting rods 16 are rotatably mounted inside the mounting shell 10. The inner ends of the two mounting rods 16 are connected to a conveying auger rod 7 via a first bevel gear set 17. The outer ends of the two mounting rods 16 are connected to the output ends of two rotating shafts 8 via a second bevel gear set 18. The two rotating shafts 8 are rotatably mounted inside the storage tank 1, symmetrically arranged about the transverse centerline of the storage tank 1, and rotate in opposite directions. A row of rotating conveyor plates 9 is mounted on the outer surface of the two rotating shafts 8. Two rows of rotating conveyor plates 9 are equally spaced. While the control motor drives the conveying auger rod 7 to transport the quartz sand material, the output end of the conveying auger rod 7 simultaneously drives two mounting rods 16 to rotate inside the mounting housing 10 via the first bevel gear set 17. At this time, the two rotating mounting rods 16 simultaneously drive two rotating shafts 8 to rotate via the second bevel gear set 18. Subsequently, the two rotating shafts 8 simultaneously drive the two rows of rotating conveyor plates 9 to aggregate the quartz sand material inside the storage tank 1, better assisting the conveying auger rod 7 in material transport.
