Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic detection, in particular to an ultrasonic detection device for a rear cover casting of an excavator. Background Art

[0002] Excavator rear cover castings are usually subjected to ultrasonic testing to ensure quality. Ultrasonic testing is a non-destructive testing technology that detects defects inside the material, such as pores, inclusions, cracks, etc., by observing the way ultrasonic waves propagate in the material.

[0003] After the casting of the rear cover of the excavator is completed, the casting is inspected by ultrasound. The traditional inspection method is to place the rear cover of the excavator at a specified position and then inspect it by ultrasound emitted by a flaw detector. In order to ensure that the staff can observe the data panel on the flaw detector during the inspection, the flaw detector needs to be constantly moved during the inspection. A cloth handle is provided on one side of the traditional flaw detector for moving the position of the flaw detector. However, when the flaw detector is picked up by the cloth handle, the cloth is bent, causing the display screen on the flaw detector to tilt, thereby affecting the staff's observation of the inspection results.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-4 An ultrasonic detection device for an excavator rear cover casting shown in the figure includes a flaw detector 1, a detection component for detecting castings is arranged on one side of the flaw detector 1, and a moving component for moving the position of the flaw detector 1 is arranged on the other side of the flaw detector 1. The moving component includes a handle 2 arranged on the other side of the flaw detector 1, and connecting blocks 3 are symmetrically arranged on the top and bottom of the handle 2. A rotating part is arranged on one side of the connecting block 3, and a threaded rod 6 is arranged on one side of the rotating part. A plurality of thread grooves 7 are horizontally symmetrically opened on the other side of the flaw detector 1, and the threaded rod 6 is threadedly inserted and connected inside the thread groove 7.

[0020] It should be noted that there are two threaded grooves 7, which correspond to the two threaded rods 6 respectively. When in use, the threaded rod 6 is inserted into the threaded groove 7 to fix the position of the threaded rod 6, and the positions of the two connecting blocks 3 are fixed by the two threaded rods 6 in the fixed position, and the two ends of the handle 2 are fixed by the two connecting blocks 3 in the fixed position, so that the position of the handle 2 is fixed by the threaded rods 6. The connecting block 3 is arranged in an arc shape to reduce the design of the angle, thereby avoiding the situation where the staff bumps into the corners and causes injuries. The handle 2, connecting block 3 and connecting parts are all made of metal. Through the design of metal material, when in use, the staff grasps the handle 2 with their hands and turns the display screen of the flaw detector 1 toward themselves, so that the staff can directly observe the detection results on the screen, avoiding the traditional situation where the display screen on the flaw detector 1 is tilted due to the bending of the fabric, which requires the body to be tilted to observe the detection results.

[0021] Furthermore, before using the flaw detector 1, the handle 2 is first placed on one side of the flaw detector 1 so that the threaded rod 6 on one side of the handle 2 is aligned with the threaded groove 7 opened on one side of the flaw detector 1, and then the threaded rod 6 is rotated into the threaded groove 7 by the rotating part, and the position of the handle 2 is fixed by the threaded rod 6. When the flaw detector 1 needs to be stored, the threaded rod 6 is rotated by the rotating part and the threaded rod 6 is turned out of the threaded groove 7, thereby separating the handle 2 from the flaw detector 1, thereby saving storage space.

[0022] Specifically, the rotating member includes a fixed block 4 fixedly connected to one side of the connecting block 3, a rotating column 5 is provided on the side of the fixed block 4 away from the connecting block 3, a threaded rod 6 is fixedly connected to one end of the rotating column 5 away from the fixed block 4, and a fixing part for fixing the position of the rotating column 5 is provided at the connection between the fixed block 4 and the rotating column 5.

[0023] It should be noted that one end of the rotating column 5 is fixedly connected to one end of the threaded rod 6, so that when the threaded rod 6 needs to be rotated, the rotating column 5 is rotated to drive the threaded rod 6 to rotate, thereby realizing the threaded rod 6 being turned into and out of the threaded groove 7.

[0024] Specifically, the fixing portion includes a connecting column 8 fixedly connected to one end of the rotating column 5 , and a connecting groove 14 is formed at one end of the fixing block 4 , and the connecting column 8 is inserted and connected inside the connecting groove 14 .

[0025] Specifically, a positioning cavity 10 is formed on the inner wall of one side of the connecting groove 14 , and a positioning column 9 is fixedly connected to one end of the connecting column 8 away from the rotating column 5 . The positioning column 9 is inserted and connected inside the positioning cavity 10 .

[0026] It should be noted that the diameter of the positioning column 9 is larger than the diameter of the connecting groove 14, so that the positioning column 9 cannot pass through the connecting groove 14, and the positioning column 9 is located in the positioning cavity 10 and cannot be moved out, so that the position of the positioning column 9 is fixed by the positioning cavity 10, and when the rotating column 5 rotates, it drives the connecting column 8 and the positioning column 9 to rotate, and the position of the rotating column 5 is limited to one side of the fixed block 4 by the positioning column 9.

[0027] Specifically, the outer wall of the rotating column 5 is provided with teeth 11 for increasing the friction between the rotating column 5 and the fingers of the staff.

[0028] Specifically, the detection component includes a conductive line 12 arranged at one side of the flaw detector 1 , and a probe 13 is arranged at one end of the conductive line 12 away from the flaw detector 1 .

[0029] It should be noted that the flaw detector 1, transmission line 12 and probe 13 are of model PXUT-350C fully digital intelligent ultrasonic flaw detector. When in use, the probe 13 is fitted to the casting to inspect the casting, and the inspection result is transmitted to the flaw detector 1 through the transmission line 12, and the result is displayed on the display screen of the flaw detector 1.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
