Description

Technical Field

[0001] This utility model relates to the field of toothed hydraulic shears, specifically a replaceable toothed hydraulic shear. Background Technology

[0002] Replaceable-tooth hydraulic shears, equipped with easily replaceable shearing teeth, can efficiently cut hard materials such as metal and steel with the powerful shearing force driven by hydraulics. They can also quickly change to adapt to different working conditions by changing the tooth type to suit different work requirements. When the teeth are worn or damaged, only the teeth need to be replaced to restore the equipment's performance, which greatly reduces maintenance costs and extends the overall service life. Its role and significance are to achieve efficient, flexible and economical high-intensity shearing operations, and improve the adaptability and economic efficiency of the equipment.

[0003] However, existing technologies have the following problems in practical use:

[0004] The working teeth and shear body of the existing product are cut from the sheet metal as a single piece. When the working teeth wear down and can no longer meet the working requirements, it is necessary to replace the entire shear body or weld new working teeth. Replacing the entire shear body will significantly increase equipment maintenance costs and waste materials and resources. Welding new working teeth will consume additional time and manpower, affect work efficiency, and the welding quality is difficult to guarantee, which may lead to a decrease in shearing accuracy, uneven stress on the equipment, and a shortened overall service life of the shear body. At the same time, frequent replacement or welding operations will also reduce the continuous operation capability of the equipment and affect the construction progress. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a replaceable toothed hydraulic shear, which has the following advantages:

[0019] This replaceable-tooth hydraulic shear features a split design that completely overcomes the limitations of existing technologies where the working teeth and shear body are integrally formed. This design allows for independent replacement of working parts. When the wear-resistant teeth or blades wear down, there is no need to replace the entire hydraulic shear body; only the worn parts need to be replaced. This significantly reduces material input for equipment maintenance, lowers maintenance costs, and avoids the waste of materials and resources caused by complete replacement. The bolted and detachable connection design eliminates the extra time and labor costs required for welding, enabling rapid component replacement, significantly improving equipment maintenance efficiency, and ensuring operational continuity.

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: a replaceable toothed hydraulic shear, which is applied to cutting hard materials such as metal and steel.

[0029] It includes a connecting frame 1, with hydraulic cylinders 2 attached to both sides of the connecting frame 1, and a hydraulic shear body 3 attached to the lower end of the connecting frame 1. Wear-resistant teeth 4 are bolted to one side of the hydraulic shear body 3, and a blade 5 is detachably attached to one side of the hydraulic shear body 3.

[0030] In this embodiment, by setting up the connecting frame 1, the oil cylinder 2, the hydraulic shear body 3, the wear-resistant teeth 4 and the blade 5, after a long period of work, when the wear-resistant teeth 4 wears out, the operator only needs to remove the bolts and nuts to disassemble and replace the wear-resistant teeth 4, which is time-saving, efficient and does not require the cooperation of other complicated tools.

[0031] In the above embodiment, as a preferred solution, a slewing bearing 6 is fixedly installed on the upper end of the connecting frame 1, and a distributor 7 is fixedly installed in the middle of the upper end of the connecting frame 1. By setting the slewing bearing 6, the operator can fix the slewing bearing 6 to the upper end of the connecting frame 1 to ensure that the rotation center of the slewing bearing 6 coincides with the central axis of the connecting frame 1, and then install the distributor 7 in the middle position of the upper end of the connecting frame 1. During installation, it is necessary to ensure that the oil inlet and oil outlet of the distributor 7 are aligned with the preset hydraulic pipeline interface. After preliminary positioning by the positioning pin, it is then tightened with bolts.

[0032] In the above embodiment, as a preferred solution, a motor seat 8 is fixedly installed on the upper end of the distributor 7, and a rotary motor 9 is fixedly installed on the upper end of the motor seat 8. By setting the motor seat 8 and the rotary motor 9, the motor seat 8 is fixed to the upper end of the distributor 7.

Finally, the rotary motor 9 is installed on the motor seat 8 so that the output shaft of the rotary motor 9 is precisely connected with the input shaft of the distributor 7, forming a drive system that can rotate 360 ​​degrees.

[0033] In the above embodiment, as a preferred option, a mounting bracket 10 is fixedly installed on the upper end of the slewing bearing 6, and a reinforcing block 11 is fixedly installed on the side of the mounting bracket 10. With the mounting bracket 10 and the reinforcing block 11, the device can be connected to other equipment as a whole and assembled to start working.

[0034] In the above embodiment, as a preferred solution, positioning blocks 12 are fixedly connected to both sides of the connecting frame 1. The side of the positioning block 12 is engaged with the upper end of the oil cylinder 2. By setting the positioning block 12, it is convenient for the staff to fix the oil cylinder 2 to both sides of the connecting frame 1.

[0035] In the above embodiment, as a preferred option, a cylinder front shaft 13 for fixing is inserted into one side of the positioning block 12. A locking baffle 14 is fixedly installed at one end of the cylinder front shaft 13. With the setting of the cylinder front shaft 13 and the locking baffle 14, when the cylinder 2 is clamped on both sides of the connecting frame 1, the cylinder front shaft 13 can be used to reinforce and position it.

[0036] In the above embodiment, as a preferred solution, the lower end of the hydraulic cylinder 2 is provided with a circular hole 15 for positioning, and the rear shaft 16 of the hydraulic cylinder is inserted into the inside of the circular hole 15. Through the arrangement of the circular hole 15 and the rear shaft 16 of the hydraulic cylinder, when the lower end of the hydraulic cylinder 2 is connected to the hydraulic shear body 3, the rear shaft 16 of the hydraulic cylinder can reinforce the connection between the hydraulic cylinder 2 and the hydraulic shear body 3.

[0037] In the above embodiment, as a preferred solution, a main shaft 17 is inserted into the side of the lower end of the connecting frame 1, and a locking nut 18 is fixedly installed at one end of the main shaft 17. By setting the locking nut 18 of the main shaft 17 and the locking nut 18, it is convenient for the operator to use the main shaft 17 to reinforce the hydraulic shear body 3 when it is clamped at the lower end of the connecting frame 1.

[0038] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0039] In this invention, the working steps of the device are as follows:

[0040] 1. First, the entire replaceable toothed hydraulic shear is fixed to the boom end of the excavator by the mounting bracket 10. The connection between the mounting bracket 10 and the boom end of the excavator is made of high-strength bolts. The bolts must be tightened to the specified torque. The reinforcing blocks 11 on the side of the mounting bracket 10 can enhance the overall strength of the mounting bracket 10 and prevent deformation during operation.

[0041] 2. Next, operate the rotary motor 9 to distribute hydraulic oil through the distributor 7, so that the hydraulic shear body 3 can rotate 360 ​​degrees. Check whether the rotation is smooth and whether there is any jamming. At the same time, observe the accuracy of the rotation angle. Then operate the oil cylinder 2 to open and close the hydraulic shear body 3 several times. Check whether the extension and retraction of the oil cylinder 2 is flexible and whether the action of the hydraulic shear body 3 is synchronized to ensure that the equipment is in normal working condition.

[0042] 3. Then, move the hydraulic shears to the material to be sheared. By operating the boom of the excavator, adjust the position and angle of the hydraulic shears so that the wear-resistant teeth 4 and the blades 5 are aligned with the shearing position. Start the oil cylinder 2. The oil inlet chamber of the oil cylinder 2 is pressurized, pushing the piston to extend. The hydraulic shear body 3 is driven to move through the rear shaft 16 of the oil cylinder, so that the wear-resistant teeth 4 and the blades 5 come closer to each other, forming a strong shearing force to shear the material.

[0043] 4. Finally, when the wear-resistant tooth 4 is worn and needs to be replaced, stop the operation of the equipment, disconnect the power source of the hydraulic system, and then use a wrench to remove the bolts connecting the wear-resistant tooth 4 and the hydraulic shear body 3. Remove the worn wear-resistant tooth 4, clean the connecting surface on the hydraulic shear body 3, remove any remaining debris and rust, install the new wear-resistant tooth 4 in its original position, and tighten the bolts. This will make it easier for the staff to replace the wear-resistant tooth 4.

[0044] 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.
