Description

Technical Field

[0001] This utility model relates to the field of hydraulic grabs, specifically to an auxiliary device for hydraulic grabs. Background Technology

[0002] A hydraulic grab is a working device that uses a hydraulic power source to power hydraulic cylinders, thereby driving the opening and closing of two combined buckets or multiple jaw plates to grab and unload bulk materials. Classified by shape, hydraulic grabs include clamshell grabs and orange-slice grabs. During operation, hydraulic grabs may encounter various complex and harsh environmental conditions, such as heavy loads, impacts, and vibrations. These factors can damage the hydraulic system. Auxiliary devices for hydraulic grabs can take timely measures in case of abnormal situations, protecting the safe operation of the hydraulic grab. These auxiliary devices play a crucial role in improving the grab's working efficiency, safety, and multifunctionality.

[0003] In the use of existing hydraulic grabs with auxiliary devices, the positioning and grabbing of the hydraulic grab rely on manual operation. Without the positioning and fine-tuning functions of the auxiliary devices, the hydraulic grab is not only inaccurate in positioning, but also reduces work efficiency. At the same time, if the positioning and grabbing are done manually, the hydraulic grab cannot accurately reach the target position, resulting in increased grabbing or placement errors. In the long run, this will limit the adaptability of the hydraulic grab to different working environments and object shapes, reduce its wide range of applications, and increase the risks associated with manual operation.

[0004] Therefore, it is necessary to invent an auxiliary device for hydraulic grabs to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for a hydraulic grab bucket. Through a fine-tuning seat, a position slot, a threaded screw, a servo motor, a threaded sleeve, a drive control module, and an object recognition sensor, this auxiliary device enables object positioning and fine-tuning functions. This allows the hydraulic grab bucket to adapt to more diverse working environments and object shapes, increasing its versatility. Furthermore, it allows for minute adjustments to the hydraulic grab bucket's position, thereby improving operational accuracy, which is particularly important for scenarios requiring precise object grabbing or placement. Simultaneously, the addition of the object recognition sensor enables the hydraulic grab bucket to automatically identify and locate target objects, thus reducing manual operation. The steps and time of operation have been streamlined, improving overall work efficiency. This addresses the problem in existing hydraulic grab bucket auxiliary devices where the position of the hydraulic grab bucket relies on manual operation to locate and grab the target object. Without the positioning and fine-tuning functions of the auxiliary device, the hydraulic grab bucket's positioning is inaccurate, reducing work efficiency. Furthermore, manual positioning and grabbing prevents the hydraulic grab bucket from accurately reaching the target position, increasing grabbing or placement errors. Over time, this limits the adaptability of the hydraulic grab bucket to different working environments and object shapes, reducing its wide applicability and increasing the risks associated with manual operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for a hydraulic grab bucket, comprising a fine-tuning auxiliary body for connecting and mounting the main body of the hydraulic grab bucket;

[0026] This utility model provides, for example Figure 1-5 An auxiliary device for a hydraulic grab bucket is shown, including a fine-tuning auxiliary body 1 for connecting and mounting the main body of the hydraulic grab bucket;

[0027] The fine-tuning base 6 is located above the fine-tuning auxiliary body 1 and is used to drive the fine-tuning auxiliary body 1 to move left and right. The fine-tuning base 6 has a position groove 7 inside, and a threaded screw 8 is movably connected inside the position groove 7. A servo motor 9 is provided at one end of the threaded screw 8, and a threaded sleeve 10 is movably connected outside the threaded screw 8. An adjusting block 11 is fixedly installed at one end of the threaded sleeve 10.

[0028] The drive control module 12 is located above the fine-tuning base 6 and is used to connect and install the connecting cable 13. One end of the connecting cable 13 is fixedly installed with an object recognition sensor 14. An upper mounting bracket 15 is fixedly installed above the fine-tuning base 6, and an upper adjustment mounting plate 16 is set above the upper mounting bracket 15. After the hydraulic grab bucket 5 is adjusted to be near the top of the object, the object recognition sensor 14 located outside the fine-tuning auxiliary body 1 senses the detailed position of the object to be grabbed below. The servo motor 9 drives the threaded screw 8 to rotate, so that the threaded sleeve 10 drives the hydraulic grab bucket 5 connected to the fine-tuning auxiliary body 1 to make fine adjustments to the left and right positions, so as to accurately position it above the object to be grabbed, so as to facilitate the hydraulic grab bucket to grab the object.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, an adjustment groove 2 is provided on the upper part of the fine-tuning auxiliary body 1, a reinforcing shim 3 is provided above the adjustment groove 2, and a fastening bolt 4 passes through the upper part of the reinforcing shim 3. One end of the fastening bolt 4 is movably connected to the hydraulic grab bucket body 5. The adjustment groove 2, the reinforcing shim 3 and the fastening bolt 4 facilitate the docking and installation of this hydraulic grab bucket auxiliary device with different hydraulic grab buckets, thus improving the overall installation and application range of the hydraulic grab bucket auxiliary device. The fine-tuning auxiliary body 1 is movably connected to the fine-tuning seat 6, and the adjustment block 11 is fixedly connected to the fine-tuning auxiliary body 1. The servo motor 9 drives the threaded screw 8 to rotate, so that the threaded sleeve 10 drives the hydraulic grab bucket body 5 connected to the fine-tuning auxiliary body 1 to perform left and right position fine-tuning.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, the number of object recognition sensors 14 is set to four, which are evenly distributed on the fine-tuning auxiliary body 1. The four sets of object recognition sensors 14 can accurately sense the detailed position of the object to be grasped below. A double-headed bolt 17 runs through the outside of the fine-tuning auxiliary body 1. One end of the double-headed bolt 17 is movably connected to a side clamping bracket 18. A connecting rod 19 is fixedly installed on the outside of the side clamping bracket 18. One end of the connecting rod 19 is fixedly connected to a connecting protective cover 20.

In this way, the operator can quickly check the condition of the connecting parts and perform necessary repairs or replacements without disassembling the entire device.

[0031] The working principle of this utility model is as follows: First, before using the hydraulic grab bucket, take out the auxiliary device for the hydraulic grab bucket, then connect the external power supply. Connect and install the auxiliary device to the hydraulic grab bucket body 5 using the adjusting groove 2, reinforcing shims 3, and fastening bolts 4 on the fine-tuning auxiliary body 1. Then, connect and install the upper mounting frame 15 and the upper adjusting mounting plate 16 to the external hoisting device in the same way. Next, install the upper side clamping frame 18, connecting rod 19, and connecting protective cover 20 on the outside of the fine-tuning auxiliary body 1 using double-headed bolts 17. The connecting protective cover 20 is located on both sides of the connection between the fine-tuning auxiliary body 1 and the hydraulic grab bucket body 5, effectively shielding and protecting the connecting parts between them, preventing them from being impacted, worn, or corroded during operation, thereby extending the service life of the connecting parts. After these preparations are completed, the external hoisting equipment can be started to move the hydraulic grab bucket body 5 above the object to be grabbed. At this time, the object recognition sensor 14 located outside the fine-tuning auxiliary body 1 senses the object to be grabbed below. The detailed position of the body is determined by connecting the drive control module 12 to the object recognition sensor 14 via the connecting cable 13. The servo motor 9 can be switched on, causing the threaded screw 8 to rotate. This allows the threaded sleeve 10 to finely adjust the left and right position of the hydraulic grab bucket 5, which is connected to the fine-tuning auxiliary body 1, precisely positioning it above the object to be grabbed. This facilitates the hydraulic grab bucket's object grabbing, giving the auxiliary device object positioning and fine-tuning functions. This allows the hydraulic grab bucket 5 to adapt to more diverse working environments and object shapes, increasing its versatility. Furthermore, it enables minute adjustments to the hydraulic grab bucket 5, improving operational accuracy. The hydraulic grab bucket 5 can then be started to grab the object below.
