Description

Technical Field

[0001] This utility model relates to the field of double-lobed grab technology, specifically a wirelessly remote-controlled double-lobed grab with adjustable opening speed. Background Technology

[0002] A double-lobed grab bucket (short for rope double-lobed grab bucket) is an effective tool for loading and unloading small granular bulk materials such as ore, nickel ore, coal, coke, yellow sand, grain, fertilizer, alumina, and sulfur, which is mounted under a crane and controlled by the raising and lowering of the crane's wire rope. The grab bucket has two lobes, resembling a seashell (hence its descriptive names: seashell grab bucket, clam shell grab bucket, flat-mouth grab bucket, etc.). The cutting edges of the lobes are beveled, and the front end is thin, reducing resistance to material during insertion, facilitating insertion, and increasing digging force. Double-lobed grab buckets are composed of single-rope double-lobed grab buckets, double-rope double-lobed grab buckets, and four-rope double-lobed grab buckets.

[0003] While existing grab buckets can effectively grab materials, they lack a mechanism for remote control of opening and closing. Operation relies on a toggle switch, and the opening speed cannot be adjusted, failing to meet the varying material delivery speeds required in different scenarios. Therefore, we propose a wirelessly controlled dual-lobed grab bucket with adjustable opening speed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a wirelessly remote-controlled double-lobed grab bucket with adjustable opening speed, thereby solving the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wireless remote-controlled double-lobed grab bucket with adjustable opening speed, comprising an installation component, a signal transmitter, a hydraulic component, and a hoisting component. A rope guide is provided at the top of the upper support beam, and a support rod is rotatably connected to the outer wall of the upper support beam. A lower support beam is provided below the upper support beam, and a sliding seat is provided at the top of the lower support beam. A fixed wedge sleeve is provided on the outer wall of the sliding seat. A hydraulic cylinder is fixedly mounted at the top of the lower support beam, and the bucket body is rotatably connected to the end of the support rod away from the upper support beam. The hydraulic assembly includes a three-way valve block, and a regulating valve is fixedly mounted on the top of the three-way valve block; The hoisting assembly includes a balance frame, a large shackle at the top of the balance frame with a long ring on the inner wall of the large shackle, a small shackle at the bottom of the balance frame with a wire rope on the inner wall of the small shackle, a pulley 1 rotatably connected to the outer wall of the upper support beam, and a pulley 2 rotatably connected to the outer wall of the sliding seat.

[0006] Through the above technical solution, and by setting up installation components, signal transmitters, hydraulic components, upper support beams, rope guides, struts, three-way valve blocks, and regulating valve structures, the grab bucket, during use, utilizes a hydraulic cylinder to connect the sliding seat to the lower support beam. When the grab bucket reaches the designated unloading position, the hydraulic oil inside the cylinder is reversed through the regulating valve, connecting the cylinder to the oil tank. This causes the cylinder output shaft to move downwards, the sliding seat to descend, and the grab bucket to open. The reversal of the regulating valve can be achieved through remote control, making it convenient for users to operate. Furthermore, if the opening speed of the grab bucket is too fast or too slow, it can be adjusted through the three-way valve block, thereby improving the practicality and automation of the grab bucket.

[0007] As a preferred technical solution of this utility model: the outer wall of the rope guide is rolledly connected to the outer walls of the wire rope, pulley one and pulley two respectively, and the end of the wire rope away from the small shackle is fixedly connected to the outer wall of the sliding seat through a fixed wedge sleeve.

[0008] Through the above technical solution, the fixed wedge sleeve structure allows the user to install both ends of the wire rope on the balance frame and the sliding seat respectively during the assembly of the grab bucket. This facilitates the user's disassembly and assembly of the wire rope, thereby improving the user's installation efficiency of the grab bucket.

[0009] As a preferred technical solution of this utility model: the number of pulleys is two, and both pulleys are symmetrically distributed along the outer wall of the upper bearing beam.

[0010] Through the above technical solution, by setting up a structure with two pulleys, the grab bucket can use the pulleys on both sides to guide and unload the wire rope during operation, thereby ensuring that the load force borne by the wire rope during operation is distributed, thus reducing the working intensity of the wire rope and improving the stability of the grab bucket during operation.

[0011] As a preferred technical solution of this utility model: the outer wall of the upper support beam is fixedly equipped with a controller, and the controller is electrically connected to the signal transmitter, the three-way valve block and the regulating valve respectively.

[0012] Through the above technical solution, and with the set controller and three-way valve block structure, when the user issues a command via remote control during operation, the controller can automatically operate the three-way valve block, signal transmitter, and regulating valve to perform operations, thereby facilitating the user's operation of the grab bucket to grab and release materials, and further improving the practicality of the grab bucket.

[0013] As a preferred technical solution of this utility model: the interfaces on both sides of the regulating valve are connected to the oil pipe of the upper chamber of the oil cylinder, and the oil pipe of the lower chamber of the oil cylinder is connected to the oil tank.

[0014] Through the above technical solution, the hydraulic oil volume in the hydraulic cylinder can be adjusted by connecting the hydraulic cylinder with the regulating valve. This allows the user to adjust the extension length of the hydraulic cylinder output shaft, enabling the grab bucket to perform material grabbing and releasing operations. It also ensures that the opening speed of the grab bucket can be adjusted by regulating the hydraulic oil flow, thereby ensuring the normal operation of the grab bucket.

[0015] As a preferred technical solution of this utility model: the outer wall of the sliding seat is provided with an oil tank, and the long ring is connected to the hook of the gantry crane.

[0016] Through the above technical solution, the oil tank structure allows the hydraulic oil discharged during the operation of the grab bucket to be stored in the oil tank, thereby ensuring that the hydraulic oil can enter the oil cylinder when the grab bucket grabs materials, thus achieving the effect of the bucket body opening, and ensuring that the subsequent use of the grab bucket will not be affected.

[0017] Compared with the prior art, this utility model provides a wirelessly controlled double-lobed grab bucket with adjustable opening speed, which has the following beneficial effects: 1. This wirelessly controlled double-lobed grab bucket with adjustable opening speed, through its installation components, upper support beam, lower support beam, bucket body, hydraulic components, three-way valve block, and regulating valve structure, allows the user to remotely fill the cylinder with hydraulic oil during use. This facilitates the user's remote control of opening and closing the grab bucket, and also allows the user to adjust the flow rate of the hydraulic oil through the regulating valve, thereby adjusting the opening and closing speed of the grab bucket.

[0018] 2. This wirelessly controlled double-lobed grab bucket with adjustable opening speed, through its hydraulic components, hoisting components, pulley one, pulley two, and fixed wedge sleeve structure, makes its operation simpler, more reliable, less prone to failure, and more efficient using remote control. It is more convenient to operate than grab buckets with rope structures. At the same time, the wire rope is fixed by a fixed wedge sleeve, which makes it easy for users to assemble and disassemble the wire rope, improving the practicality of the grab bucket.

[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] like Figure 1-5 As shown, the present invention provides a wireless remote-controlled double-lobed grab bucket with adjustable opening speed, including an installation component 1, a signal transmitter 2, a hydraulic component 3, and a hoisting component 4. The top of the upper support beam 101 is provided with a rope guide 102, and the outer wall of the upper support beam 101 is rotatably connected with a support rod 103. The lower support beam 105 is provided below the upper support beam 101, and the top of the lower support beam 105 is provided with a sliding seat 104. The outer wall of the sliding seat 104 is provided with a fixed wedge sleeve 107, and the top of the lower support beam 105 is fixedly equipped with a hydraulic cylinder 108. The end of the support rod 103 away from the upper support beam 101 is rotatably connected to the bucket body 106. The hydraulic assembly 3 includes a three-way valve block 301, and a regulating valve 302 is fixedly mounted on the top of the three-way valve block 301; The hoisting assembly 4 includes a balance frame 401, a large shackle 403 on the top of the balance frame 401, a long ring 402 on the inner wall of the large shackle 403, a small shackle 404 on the bottom of the balance frame 401, a wire rope 405 on the inner wall of the small shackle 404, a pulley 406 rotatably connected to the outer wall of the upper support beam 101, and a pulley 407 rotatably connected to the outer wall of the sliding seat 104.

[0023] The advantages are that, through the structure of the installation component 1, signal transmitter 2, hydraulic component 3, upper support beam 101, rope guide 102, support rod 103, three-way valve block 301, and regulating valve 302, the grab bucket, during use, uses the hydraulic cylinder 108 to connect the sliding seat 104 to the lower support beam 105. When the grab bucket reaches the designated unloading position, the hydraulic oil inside the hydraulic cylinder 108 is reversed through the regulating valve 302, connecting the hydraulic cylinder 108 to the oil tank. This causes the output shaft of the hydraulic cylinder 108 to move downward, the sliding seat 104 to descend, and the grab bucket to open. The reversal of the regulating valve 302 can be achieved through remote control, making it convenient for users to operate. Furthermore, if the opening speed of the grab bucket is too fast or too slow, it can be adjusted through the three-way valve block 301, thereby improving the practicality and automation of the grab bucket.

[0024] Specifically: the outer wall of the rope guide 102 is rolledly connected to the outer walls of the wire rope 405, pulley 406 and pulley 407 respectively, and the end of the wire rope 405 away from the small shackle 404 is fixedly connected to the outer wall of the sliding seat 104 through the fixed wedge sleeve 107.

[0025] The advantage is that, through the fixed wedge sleeve 107 structure, the user can install the two ends of the wire rope 405 on the balance frame 401 and the sliding seat 104 respectively through the fixed wedge sleeve 107 during the assembly of the grab bucket, which makes it convenient for the user to assemble and disassemble the wire rope 405, thereby improving the user's installation efficiency of the grab bucket.

[0026] Specifically, there are two pulleys 406, and both pulleys 406 are symmetrically distributed along the outer wall of the upper bearing beam 101.

[0027] The advantage is that, through the two pulleys 406 structure, the grab bucket can guide and unload the wire rope 405 during operation by using the pulleys 406 on both sides, thereby ensuring that the load force borne by the wire rope 405 during operation is distributed, thus reducing the working intensity of the wire rope 405 and improving the stability of the grab bucket during operation.

[0028] Specifically: The outer wall of the upper support beam 101 is fixedly equipped with a controller, and the controller is electrically connected to the signal transmitter 2, the three-way valve block 301, and the regulating valve 302 respectively.

[0029] The advantage is that, through the structure of the controller and the three-way valve block 301, when the user issues a command via remote control during operation, the controller can automatically operate the three-way valve block 301, the signal transmitter 2, and the regulating valve 302 to perform operations, thereby facilitating the user's operation of the grab bucket to grab and release materials, and further improving the practicality of the grab bucket.

[0030] Specifically: the interfaces on both sides of the regulating valve 302 are connected to the oil pipe in the upper chamber of the oil cylinder 108, and the oil pipe in the lower chamber of the oil cylinder 108 is connected to the oil tank.

[0031] The advantage is that the structure connecting the hydraulic cylinder 108 to the regulating valve 302 allows the hydraulic oil volume in the hydraulic cylinder 108 to be adjusted, which makes it easy for the user to adjust the extension length of the output shaft of the hydraulic cylinder 108. This enables the grab bucket to perform material grabbing and releasing operations, and also ensures that the opening speed of the grab bucket can be adjusted by regulating the hydraulic oil flow, thereby ensuring the normal operation of the grab bucket.

[0032] Specifically: the outer wall of the sliding seat 104 is equipped with an oil tank, and the long ring 402 is connected to the hook of the gantry crane.

[0033] The advantage is that, through the oil tank structure, the hydraulic oil discharged during the operation of the grab bucket is stored in the oil tank, thereby ensuring that the hydraulic oil can enter the oil cylinder 108 when the grab bucket grabs materials, so as to achieve the effect of opening the bucket body 106, and thus ensuring that the subsequent use of the grab bucket will not be affected.

[0034] Working Principle: First, the user can remotely control the hydraulic oil to enter the cylinder 108, causing the output shaft of the cylinder 108 to extend. Then, the lower support beam 105 descends, opening the grab bucket to grab materials. After grabbing, the output shaft of the cylinder 108 retracts. To release it again, the user can discharge hydraulic oil to retract the output shaft. Simultaneously, the three-way valve block 301 adjusts the hydraulic oil output, allowing the user to adjust the opening and closing speed of the grab bucket, thus facilitating operation and improving the automation and practicality of the grab bucket. During operation, the remote control method makes the working principle simpler and more reliable, with a low failure rate, thus improving the user's work efficiency. It is more convenient to operate than a rope grab bucket, and the fixing structure of the wire rope 405 facilitates user assembly and disassembly, further improving the efficiency of wire rope assembly and disassembly.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
