Description

Technical Field

[0001] This utility model relates to the field of grab bucket technology, specifically a grab bucket anti-sway stabilizer device. Background Technology

[0002] A grab bucket is a special tool used by cranes to grab dry bulk goods. It consists of two or more bucket-shaped jaw plates that can be opened and closed to form a storage space. During loading, the jaw plates close in the material pile, and the material is grabbed into the storage space. During unloading, the jaw plates open while suspended above the material pile, and the material scatters on the pile. In the existing technology, when grabbing materials, the grab bucket is prone to deviation when in contact with the material, which causes the grab bucket's posture to change. After grabbing materials, it is prone to swaying when rising, resulting in insufficient stability.

[0003] For example, patent publication number CN221733620U describes a grab bucket structure, including a first grab bucket body and a second grab bucket body, which are hinged together. The first grab bucket body has two first bucket teeth, and the second grab bucket body has three second bucket teeth. Two interval slots are provided between the three second bucket teeth. When the first grab bucket body and the second grab bucket body are closed, each first bucket tooth is located in one interval slot. In this grab bucket structure, when the first grab bucket body and the second grab bucket body are closed, the first bucket teeth can be transferred to the interval slots, so that the first bucket teeth and the second bucket teeth cooperate to crush materials. At the same time, it can also accurately grab some relatively small materials, improving the versatility of the grab bucket structure. However, this grab bucket is prone to deviation when contacting materials, causing changes in the grab bucket's posture. After grabbing materials, it is prone to swaying when rising, resulting in insufficient stability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grab bucket anti-sway stabilizer device, which solves the problem that when the grab bucket is grabbing materials, the contact between the grab bucket and the material is prone to deviation, causing changes in the grab bucket's posture and making it prone to swaying when rising after grabbing materials, resulting in insufficient stability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a grab bucket anti-sway stabilizer device, including a grab bucket, a hanger is provided on the top of the grab bucket, a stabilizing guide mechanism is installed at both ends of the hanger, and an opening and closing mechanism is provided on the grab bucket;

[0008] Preferably, both the output shaft end of the drive motor and the lifting screw are fixedly connected to transmission gears. The output shaft end of the drive motor is connected to the lifting screw through two transmission gears, so that the drive motor can drive the lifting screw to rotate.

[0009] Preferably, an L-shaped mounting bracket is fixedly connected to the drive motor, and the L-shaped mounting bracket is fixedly installed on the support base, which makes it convenient to install the drive motor and keeps the drive motor stable.

[0010] Preferably, the two guide rods are disposed through the support base, and the first movable seat and the second movable seat are slidably connected to the support base through the guide rods, so as to guide the movement of the first movable seat and the second movable seat.

[0011] Preferably, the top end of the reset spring abuts against the limiting seat, and the bottom end of the reset spring abuts against the base, which can play a reset role for the base.

[0012] Preferably, the opening and closing mechanism includes two pairs of rotating rods, the top ends of the two pairs of rotating rods are rotatably connected to the hanger, the bottom ends of the rotating rods are rotatably connected to the grab bucket, a connecting shaft is fixedly connected between the two pairs of rotating rods, a first hydraulic cylinder is rotatably connected between the two connecting shafts, a first connecting seat is rotatably connected to the connecting shaft, a second connecting seat is rotatably connected to the grab bucket, and a second hydraulic cylinder is installed between the first connecting seat and the second connecting seat, so that the grab bucket can open at a larger angle and the material inside can be fully discharged.

[0013] This invention provides a grab bucket anti-sway stabilizer device. Compared with the prior art, it has the following advantages:

[0014] 1. This grab bucket anti-sway stabilizer device measures the distance between the base and the ground using a laser rangefinder, drives the motor to move the base to the ground for support, and then lowers the grab bucket.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-3This utility model provides a technical solution: a grab bucket anti-sway stabilizer device, including a grab bucket 1, a hanger 3 on the top of the grab bucket 1, a stabilizing guide mechanism 2 installed at both ends of the hanger 3, and an opening and closing mechanism 4 on the grab bucket 1. The stabilizing guide mechanism 2 can play a guiding and limiting role when the grab bucket 1 grabs materials, making the grab bucket 1 more stable during the grabbing process, preventing the grab bucket 1 from swaying, and effectively improving the stability of use.

[0023] The stabilizing guide mechanism 2 includes two support seats 201, which are symmetrically arranged on both sides of the hanger 3 and fixedly connected to the hanger 3, so that the support seats 201 can remain stable and provide support. A lifting screw 202 is rotatably connected to the support seat 201. A limit block 203 is fixedly connected to the top of the lifting screw 202, which can limit the movement of the first movable seat 206 and prevent the first movable seat 206 from separating from the lifting screw 202. A drive motor 204 is drivenly connected to one side of the lifting screw 202. A transmission gear 205 is fixedly connected to the output shaft end of the drive motor 204 and the lifting screw 202. The output shaft end of the drive motor 204 is transmitted to the lifting screw 202 through the two transmission gears 205. A dynamic connection is established, enabling the drive motor 204 to drive the lifting screw 202 to rotate. An L-shaped mounting bracket is fixedly connected to the drive motor 204, which is fixedly mounted on the support base 201. This facilitates the installation of the drive motor 204 and ensures its stability. A first movable seat 206 is threaded onto the lifting screw 202. A second movable seat 208 is located at the bottom of the first movable seat 206. A guide rod 207 is fixedly connected between the first movable seat 206 and the second movable seat 208. The two guide rods 207 pass through the support base 201, and the first movable seat 206 and the second movable seat 208 are slidably connected to the support base 201 via the guide rods 207. This allows for the rotation of the first movable seat 206 and the second movable seat 208. The movement of seat 208 serves a guiding function. A laser rangefinder 209 is fixedly connected inside the second movable seat 208. During operation, the laser rangefinder 209 emits a single or a series of short pulsed laser beams towards the target. A photoelectric element receives the laser beam reflected from the target, and a timer measures the time from emission to reception, calculating the distance from the rangefinder to the target. This allows for the measurement of the distance between base 212 and the ground. The distance between base 212 and the ground is the value measured by the laser rangefinder 209 minus the distance between the bottom surface of the limiting seat 210 and the bottom surface of base 212. This facilitates the easy movement of base 212 to different positions, adapting to different ground heights and preventing the grab bucket 1 from tilting. Furthermore, the laser rangefinder 209 is equipped with an M68H... The C16 microcontroller controller enables control of the drive motor 204. The drive motor 204 stops at a specified position via an encoder, allowing the base 212 to be moved to a specified position. A limit seat 210 is fixedly connected to one side of the second movable seat 208. Two limit rods 211 are slidably connected to the limit seat 210. The bottom of each limit rod 211 is fixedly connected to the base 212. Each limit rod 211 is equipped with a return spring 213. The top of the return spring 213 abuts against the limit seat 210, and the bottom of the return spring 213 abuts against the base 212, thus resetting the base 212. Anti-detachment blocks 214 are fixedly connected to the top of each limit rod 211 to prevent the limit rod 211 from separating from the limit seat 210.

[0024] Please see Figure 1 and Figure 4 The opening and closing mechanism 4 includes two pairs of rotating rods 401. The top ends of the two pairs of rotating rods 401 are rotatably connected to the hanger 3, and the bottom ends of the rotating rods 401 are rotatably connected to the grab bucket 1. A connecting shaft 402 is fixedly connected between the two pairs of rotating rods 401. A first hydraulic cylinder 403 is rotatably connected between the two connecting shafts 402. A first connecting seat 404 is rotatably connected to the connecting shaft 402, and a second connecting seat 405 is rotatably connected to the grab bucket 1. A second hydraulic cylinder 406 is installed between the first connecting seat 404 and the second connecting seat 405. The first hydraulic cylinder 403 can drive the two pairs of rotating rods 401 to rotate. The rotation of the rotating rods 401 drives the grab bucket 1 to open and close. Then, the second hydraulic cylinder 406 drives the grab bucket 1 to rotate, so that the grab bucket 1 can open and close at a larger angle, allowing the material inside to be fully discharged and avoiding material residue.

[0025] During operation, the laser rangefinder 209 measures the distance between the base 212 and the ground. The controller controls the drive motor 204 to work. The drive motor 204 drives the lifting screw 202 to rotate through the transmission gear 205. The rotation of the lifting screw 202 drives the first movable seat 206 to move. The movement of the first movable seat 206 drives the guide rod 207 to move. The movement of the guide rod 207 drives the second movable seat 208 to move. The movement of the second movable seat 208 drives the limit seat 210 to move. The movement of the limit seat 210 drives the base 212 to move, moving the base 212 to the ground. Then, the grab bucket 1 is lowered. The lowering of the grab bucket 1 drives the limit seat 210 to move along the limit rod 211, which guides and limits the movement of the grab bucket 1. When the grab bucket 1 is performing the grabbing action, it prevents the grab bucket 1 from shifting under force, making the grab bucket 1 more stable during the grabbing process and preventing the grab bucket 1 from swaying, effectively improving the stability of use.
