Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and in particular relates to an angle-adjustable steel structure internal testing device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Before steel structures are put into use, they must be inspected to check for defects or unevenness, and information such as the size, location, nature and quantity of defects must be provided.

[0003] Traditional inspection equipment typically uses rigid straight tube structures or probes with fixed bending angles. When the object being inspected has a bent structure, the equipment cannot adjust the travel angle in real time, making it difficult for the probe to penetrate into the curved area, creating a blind spot. This makes it difficult to handle both straight and curved inspection scenarios. At the same time, traditional inspection equipment often uses a single illumination mode. If a diffused light mode is used, although the field of view is large, the local brightness is insufficient, making it difficult to clearly identify minute defects. If a focused light mode is used, although the local clarity is high, the field of view is narrow. Initially, when locating problem points, it is necessary to repeatedly move the equipment, resulting in low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an angle-adjustable steel structure internal inspection device to solve the problems of traditional inspection equipment probes being unsuitable for curved structures and having a single lighting mode.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an angle-adjustable steel structure internal detection device, including an installation tube, a data cable installed inside the installation tube, a bending mechanism, the bending mechanism including a support frame installed at one end of the installation tube, two rotating rods connected to one side of the support frame, a first assembly block connected to one end of the rotating rods, a second assembly block installed at one end of the first assembly block, the protrusion of the first assembly block being configured to insert into the recess of the second assembly block, the protrusion of the first assembly block being inserted into the recess of the second assembly block limiting the rotation of the second assembly block, wherein, an optical mechanism, the optical mechanism including an integrated base connected to one end of the data cable, a light control cover being sleeved on the outside of the integrated base, the light control cover being configured to move along the axis of the integrated base to protect the integrated base.

One end of the first assembly block is connected to a connecting rod, and one end of the rotating rod and the connecting rod are connected to a sliding column. The sliding column is slidably connected to the sliding groove at the corresponding position.

[0007] Preferably, one end of the mounting tube is connected to an integrated processor, the integrated processor is connected to a data cable, and the bending mechanism is located at the other end of the mounting tube.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model provides a technical solution: an angle-adjustable steel structure internal inspection device, including an installation tube 1, a data cable 7 inside the installation tube 1, a bending mechanism 4, the bending mechanism 4 including a support frame 401 at one end of the installation tube 1, two rotating rods 402 connected to one side of the support frame 401, a first assembly block 403 connected to one end of the rotating rods 402, a second assembly block 409 at one end of the first assembly block 403, the protrusion of the first assembly block 403 being configured to insert into the recess of the second assembly block 409, and limiting the rotation of the second assembly block 409 after the protrusion of the first assembly block 403 is inserted into the recess of the second assembly block 409, wherein the optical mechanism 8 includes an integrated base 801 connected to one end of the data cable 7, a light control cover 807 sleeved on the outside of the integrated base 801, the light control cover 807 being configured to move along the axis of the integrated base 801, and can protect the integrated base 801.

[0022] Both the first assembly block 403 and the second assembly block 409 have stroke grooves inside, and both sides of the outer walls of the first assembly block 403 and the second assembly block 409 have sliding grooves. One end of the first assembly block 403 is connected to a connecting rod 407, and one end of the rotating rod 402 and the connecting rod 407 are connected to a sliding column 406. The sliding column 406 is slidably connected in the sliding groove at the corresponding position.

[0023] The outer wall of the second assembly block 409 has a connecting groove 408. One end of the mounting pipe 1 is connected to the first connecting pipe 5, and one end of the first connecting pipe 5 is connected to the second connecting pipe 6. The inner walls of the first connecting pipe 5 and the second connecting pipe 6 are provided with columns at the same positions, and the columns are inserted into the corresponding connecting grooves 408 on the outer wall of the second assembly block 409.

[0024] Two connecting buckles 2 are connected to the outer wall of the mounting tube 1. A base 11 is provided above the mounting tube 1. The connecting buckles 2 are snapped into the corresponding positions on the outer wall of the base 11. A display screen 12 is connected to the top of the base 11. A branch tube 3 is connected to the top of the mounting tube 1. One end of the data cable 7 is inserted into the branch tube 3 and is connected to one side of the base 11. A battery compartment cover 10 is connected to the bottom of the base 11.

[0025] Specifically, the mounting pipe 1, the first connecting pipe 5, and the second connecting pipe 6 are connected by a snap-fit. A second assembly block 409, located at one end of the mounting pipe 1, is fixedly connected to the inner wall of the first connecting pipe 5 by inserting a rod from the inner wall of the first connecting pipe 5 into the connecting groove 408. The second assembly block 409 moves with the first connecting rod 407. The first assembly block 403 and the second assembly block 409 have the same cross-sectional shape, both being arrow-shaped. When the first connecting pipe 5 is connected to the mounting pipe 1, the protrusion of the first assembly block 403... The first connecting tube 5 is inserted into the recess of the second assembly block 409, and the two are locked in position as a whole. When the first connecting tube 5 separates from the mounting tube 1, the first connecting tube 5 drives the second assembly block 409 forward. The sliding post 406 connected to one end of the connecting rod 407 slides in the sliding groove 405 of the second assembly block 409. When the sliding post 406 connected to the connecting rod 407 slides from one end of the sliding groove 405 of the second assembly block 409 to the other end, the second assembly block 409 drives the first assembly block 403 forward through the connecting rod 407. The sliding post 406 connected to one end of the rotating rod 402 slides in the sliding groove 405 of the first assembly block 403. When the sliding post 406 connected to the rotating rod 402 slides from one end of the sliding groove 405 of the first assembly block 403 to the other end, the bending mechanism 4 completes its unfolding. The first assembly block 403 can rotate around the sliding post 406 at one end of the rotating rod 402, and the second assembly block 409 can slide around the sliding post 406 at one end of the connecting rod 407. The first assembly block 403 and the second assembly block 409... Each of the 9 components has a stroke groove 404 inside to prevent the first assembly block 403 and the second assembly block 409 from interfering with the rotating rod 402 and the connecting rod 407 during rotation. The first assembly block 403 and the second assembly block 409 can rotate independently in different directions, allowing the first connecting pipe 5 to bend arbitrarily relative to the mounting pipe 1. The second connecting pipe 6 can bend arbitrarily relative to the first connecting pipe 5 using the same principle. The data cable 7 is made of flexible rubber, allowing the equipment to penetrate into the interior of a steel structure with complex angle changes for testing.

[0026] It should be further explained that the buckle mentioned above is a device in the field of mechanical engineering that connects parts through locking components. It uses elastic deformation and friction mechanism to fix the parts. This part is a well-known technology in the field and will not be elaborated here.

[0027] One end of the mounting tube 1 is connected to an integrated processor 9, which is connected to a data cable 7. A bending mechanism 4 is located at the other end of the mounting tube 1.

[0028] The outer wall of the integrated base 801 is provided with multiple insertion slots 802 around the axis. A movable ring 805 is sleeved on the outside of the integrated base 801. One side of the movable ring 805 is connected to one side of the light control cover 807, and the other side of the movable ring 805 is connected to multiple insertion rods 806. The insertion rods 806 are inserted into the corresponding insertion slots 802.

[0029] The optical mechanism 8 also includes a camera 804 disposed at one end of the integrated base 801, and a plurality of lighting lamps 803 are arranged around the camera 804 around the axis.

[0030] Specifically, the outer wall of the integrated base 801 has multiple insertion slots 802, with two insertion slots 802 arranged in a group along the axial direction. The moving ring 805 surrounds the outside of the integrated base 801. The light control cover 807 has a ring structure of light-concentrating material on its side and a transparent circular film on its top. When the insertion rod 806 connected to one side of the moving ring 805 is inserted into the insertion slot 802 near the camera 804, the light control cover 807 completely covers the side of the integrated base 801 where the lighting lamp 803 and the camera 804 are installed, making the light more concentrated, increasing the local illumination intensity, and making the local shooting clearer. When the moving ring 805 is moved so that the insertion rod 806 connected to one side is inserted into the insertion slot 802 away from the camera 804, the light control cover 807 only partially covers the side of the integrated base 801 where the lighting lamp 803 and the camera 804 are installed, making the light dispersed, expanding the illumination range, and obtaining a wider field of view.

[0031] Working principle: In use, the operator pulls the connecting buckle 2 to both sides to remove the base 11, inserts two batteries into the battery compartment at the bottom, and then aligns the base 11 with the battery compartment cover 10 and installs it back in place. Then, the operator aligns the interface of the display screen 12 with the interface on the top of the base 11 and installs it. The operator starts the camera 804 and the lighting lamp 803 through the button below the display screen 12. The image captured by the camera 804 is processed by the integrated processor 9 and transmitted to the display screen 12 for the operator to view. First, the light control cover 807 is adjusted to partially cover the camera 804 to obtain a wider field of view for easier detection of the target. When the steel structure to be detected is a straight structure, the first connecting pipe 5 and the second connecting pipe 6 are directly inserted into the structure for observation. When the steel structure to be detected has a curved structure, the first connecting pipe 5 and the second connecting pipe 6 are separated so that they can be inserted into the structure along the curved surface. When the target is detected, the light control cover 807 is adjusted to completely cover the camera 804 to concentrate the light and obtain a clearer image.
