Description

Technical Field

[0001] The invention relates to the field of scrapped car dismantling, and in particular to a gantry scissor blade quick locking device and a control method. Background Art

[0002] Existing gantry shears are all directly locked with hexagonal nut pre-tightening force. Due to the small space for the installation of hexagonal nuts, it is difficult to operate and cannot fully guarantee that the predetermined pre-tightening force can be achieved during installation, which is time-consuming and labor-intensive. The gantry shears will vibrate during operation and the shearing force is very large. After working for a long time, the locking nut may loosen and the blade may not be locked, resulting in damage to the blade. Summary of the invention

[0003] The purpose of the present invention is to provide a gantry scissors blade quick locking device to address the above-mentioned problems. This locking device ensures the pre-tightening force of the bolt through a hydraulic puller, thereby ensuring the reliability of the fixed installation of the blade and effectively preventing it from being damaged by vibration during operation. Moreover, its disassembly and assembly is quick and simple, saving time and effort.

[0004] In order to realize the above-mentioned technical features, the purpose of the present invention is achieved as follows: a gantry shears blade quick locking device, which includes an ultra-high pressure hydraulic pump station for providing hydraulic power to the entire locking device, the ultra-high pressure hydraulic pump station is connected to the first diversion block through a main high-pressure hydraulic hose; multiple outlets on the side of the first diversion block are respectively connected to the hydraulic puller through branch high-pressure hydraulic hoses, the hydraulic puller is mounted on the screw of the blade mounting bolt, and one side of the hydraulic puller is flush with the gantry shear main machine, and the other side is flush with the hexagonal nut installed on the blade mounting bolt.

[0005] The other side outlet of the first diverter block is connected to the first high-pressure hard pipe, the first high-pressure hard pipe is connected to the right-angle adapter block installed on the upper beam of the gantry shear main machine, the right-angle adapter block is connected to the adapter block through the intermediate hydraulic hose, and the adapter block is connected to the second diverter block through the second high-pressure hard pipe.

[0006] The multiple outlets of the second diverter block are respectively connected to the hydraulic puller through high-pressure hydraulic hoses. The hydraulic puller is sleeved on the blade mounting bolt rod, one side of which is flush with the gantry shear main machine, and the other side is flush with the hexagonal nut installed on the blade mounting bolt. A protective plate is installed on the outside of the hydraulic puller.

[0007] The hydraulic lifter comprises a cylinder body, a piston is fitted inside the cylinder body, a seal is arranged between the piston and the cavity of the cylinder body, and a pipe joint for connecting the cavity is installed on the outer wall of the cylinder body.

[0008] The ultra-high pressure hydraulic pump station is provided with a pressure monitoring system, which can timely feed back the tightening force of the hydraulic puller to the operating table, and timely supplement the pressure of the hydraulic puller to ensure that the pre-tightening force of the bolt remains unchanged.

[0009] A control method for a gantry scissor blade quick locking device comprises the following steps:

[0010] When the ultra-high pressure hydraulic pump station is working, high pressure hydraulic oil will be generated. The ultra-high pressure hydraulic oil is connected to the first diverter block through the main high pressure hydraulic hose. At the same time, the hydraulic oil of the first diverter block is connected to the right angle adapter block through the first high pressure hard pipe, and further connected to the adapter block on the scissor slide through the intermediate hydraulic hose. The adapter block is connected to the second diverter block of the scissor slide through the second high pressure hard pipe;

[0011] The side multiple oil outlets on the first shunt block and the second shunt block are connected to the hydraulic pullers on the main machine and the scissor slide through the branch high-pressure hydraulic hose and the high-pressure hydraulic hose to generate tension, and the hexagonal nut installed at the rear end of the hydraulic puller is connected to the blade mounting bolt, and the hydraulic tensioner quickly locks the blade and maintains pressure continuously;

[0012] During the pre-tightening process of the hydraulic puller, the tensioning force of the hydraulic puller is monitored in real time through the pressure monitoring system, and the hydraulic puller is automatically pressurized to ensure that the pre-tightening force remains unchanged;

[0013] When the blade needs to be replaced, the pressure is released on the ultra-high pressure hydraulic pump station system. The hydraulic puller will be unlocked and the blade mounting bolts will have no pre-tightening force. The hexagonal nut can be removed quickly and conveniently, and then the blade can be replaced.

[0014] The present invention has the following beneficial effects:
