Description

A crane alignment detection mechanical point limit device Technical Field

[0001] This utility model relates to the field of crane technology, specifically to a crane correction detection mechanical point limiting device. Background Technology

[0002] Cranes, as lifting machinery in modern industrial production, have high requirements in some important occasions. Large gantry cranes are key equipment for shipbuilding enterprises, and their correction devices come in various forms. Due to various reasons, existing mechanical limit devices have the disadvantages of inconvenient installation, complex structure, and complicated positioning in actual use. Moreover, the limit blocks of existing crane limit devices are generally surface positioning, lacking line and point positioning, which is not conducive to improving positioning accuracy. Therefore, a crane correction detection mechanical point limit device is needed.

[0003] Existing technologies, such as CN208883329U, describe a crane deviation detection mechanical point limiting device. When the main beam of the crane deviates upward or downward, the deviation can be determined by measuring the extension and contraction of the spring. When the crane deviates downward, the spring continues to extend, and the amount of extension is used to determine the amount of deviation. When the crane deviates upward, the spring contracts, and the amount of contraction is used to determine the amount of deviation.

[0004] However, this device still has some shortcomings in its use. It only judges the offset by the extension of the spring and the amount of extension. When the crane moves upward, the spring contracts and the offset is judged by the amount of contraction. This has certain limitations and low efficiency. The device does not have a shock absorption effect during use, which makes the detected mechanical point prone to offset, affecting the work and reducing work efficiency and service life. Summary of the Invention

[0005] The purpose of this utility model is to provide a crane correction detection mechanical point limiting device to solve the problem in the background art where the device simply judges the offset by the extension of the spring and the amount of extension. When the crane deviates upward, the spring contracts and the offset is judged by the amount of contraction. This has certain limitations and low efficiency. In the process of use, the device does not have a shock absorption effect, and the detected mechanical point is prone to deviation, which affects the operation and reduces the efficiency and service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A crane alignment detection mechanical point limiting device includes a crane main beam, with a limiting component and a connecting component respectively provided at the bottom of the crane main beam, and the connecting component located on the side of the limiting component;

[0008] The limiting assembly includes a guide plate at the bottom of the crane main beam. A fixing groove is provided on the top of the guide plate.

[0010] As a preferred embodiment of this utility model, a hinged seat is fixedly connected to the bottom of the main beam of the crane, a connecting rod is hinged to the bottom of the hinged seat, a second fixed seat is fixedly connected to the side of the connecting rod, and a hinged rod is hinged between the second fixed seat and the first fixed seat.

[0011] As a preferred embodiment of this utility model, the top of the guide plate is provided with a guide hole, the guide hole is located on the side of the fixing groove, and the connecting rod extends to the bottom of the guide plate through the guide hole.

[0012] As a preferred embodiment of this utility model, a sealing plate is snapped into the opening of the mounting groove, and the sealing plate is located on the side of the displacement sensor.

[0016] As a preferred embodiment of this utility model, the crane main beam and the guide plate are positioned opposite each other, and the outer surface of the crane main beam is coated with an anti-corrosion solution.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1.

A displacement sensor 208 is fixedly connected in the mounting groove 209. A hinge seat 5 is fixedly connected to the bottom of the crane main beam 1. A connecting rod 4 is hinged to the bottom of the hinge seat 5. A second fixed seat 206 is fixedly connected to the side of the connecting rod 4. A hinge rod 205 is hinged between the second fixed seat 206 and the first fixed seat 204. An installation part 6 is fixedly connected to the bottom of the connecting rod 4. The installation part 6 is located at the bottom of the guide plate 201. The crane main beam 1 and the guide plate 201 are positioned opposite each other. The outer surface of the crane main beam 1 is coated with an anti-corrosion solution.

[0029] The connecting rod 4 is connected to the first fixed seat 204 through the hinge rod 205. The moving block 203 presses against the first spring 211. At the same time, a displacement sensor 208 is provided on the side of the moving block 203. Through the cooperation of the displacement sensor 208 and the first spring 211, the connecting rod 4 can be limited, and the staff can understand the value of the offset.

[0030] In this embodiment, as shown in Figures 1 and 4, the connecting assembly 3 includes a sliding rod 301 at the bottom of the crane beam 1. The sliding rod 301 is fixedly connected to the crane beam 1. A second spring 302 is sleeved on the outer surface of the sliding rod 301. The bottom of the sliding rod 301 passes through the guide plate 201 and is slidably connected to the guide plate 201. The second spring 302 is located at the top of the guide plate 201 and abuts against the guide plate 201. A guide hole 304 is provided at the top of the guide plate 201. The guide hole 304 is located on the side of the fixing groove 207. The connecting rod 4 extends to the bottom of the guide plate 201 through the guide hole 304.

There are two sliding rods 301, and the two sliding rods 301 are positioned opposite each other.

[0031] The sliding rod 301 is provided with a second spring 302 on its outer surface. The sliding rod 301 is slidably connected to the guide plate 201. As a result, vibration occurs between the main beam 1 of the crane and the guide plate 201 during operation, and the second spring 302 has the effect of shock absorption.

The connecting rod 4 is slidably connected to the guide hole 304. Since a hinge rod 205 is hinged between the first fixed seat 204 and the second fixed seat 206, if the connecting rod 4 deviates during operation, the connecting rod 4 will be stopped by the cooperation of the hinge rod 205 and the first fixed seat 204. The moving block 203 presses against the first spring 211. At the same time, a displacement sensor 208 is provided on the side of the moving block 203.

A second spring 302 is provided on the outer surface of the sliding rod 301. The sliding rod 301 is slidably connected to the guide plate 201. Therefore, when vibration occurs between the crane main beam 1 and the guide plate 201 during operation, the second spring 302 has a shock absorption effect, which improves the stability and service life between the crane main beam 1 and the guide plate 201.
