Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a quality testing device for a conical cement pole. Background Technology

[0002] Tapered concrete poles are a common type of utility pole and one of the most widely used. They are produced and purchased in bulk. Currently, the acceptance of tapered utility poles is mainly done manually in batches. This requires photographing and inspecting for cracks and other defects on the poles. Inspecting each tapered utility pole takes a long time, and the large number of inspections puts a significant strain on people's physical strength and acceptance capabilities.

[0003] Chinese patent application number 202420615297.1 discloses a quality inspection device for conical cement poles, belonging to the technical field of inspection equipment. It includes a guide rail, and an active support vehicle and an auxiliary support vehicle movably mounted on top of the guide rail. A detection mechanism is located on one side of the guide rail, comprising a lifting rod fixedly mounted on one side of the guide rail, and a flaw detector and a vision camera fixedly mounted on one side of the lifting rod and located above the guide rail. This conical cement pole quality inspection device, through the arrangement of the active and auxiliary support vehicles, adjusts the distance between them to place the conical cement pole on them. A first motor drives the active wheel to move the conical cement pole through the detection mechanism at a uniform speed. During this process, the flaw detector performs flaw detection, and the vision camera takes pictures. The electric telescopic rods on the active and auxiliary support vehicles are adjusted to keep the central axis of the conical cement pole horizontal, facilitating rotation.

[0004] However, the tapered cement pole quality inspection device still has some shortcomings in actual use. For example, in order to inspect the cement pole from all angles, the cement pole needs to be rotated during the inspection process. The rotation process is cumbersome and difficult to control, which affects the inspection efficiency. In addition, the lack of a stable pole positioning mechanism during the inspection process makes the tapered pole prone to rolling deviation, resulting in distorted inspection data. Summary of the Invention The purpose of this invention is to provide a quality testing device for tapered cement poles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tapered cement pole quality testing device, comprising a testing platform assembly, wherein a testing component is provided in the middle of the top surface of the testing platform assembly, and multiple pole placement components are provided on the top surface of the testing platform assembly from one side to the other. The testing platform assembly includes a mounting plate, on the back center of which a linear motor is fixedly mounted. A connecting bent rod is fixedly mounted on the back of the slider of the linear motor, and a toothed plate is fixedly mounted on one end of the connecting bent rod. The detection component includes a support, an outer ring is fixedly installed at the top of the support, a transition groove is opened on the front of the outer ring, a rotating ring is rotatably installed in the transition groove, and two mounting blocks are fixedly installed on the inner ring surface of the rotating ring. The two mounting blocks are symmetrically arranged, and a CCD camera and a flaw detector head are fixedly installed on the opposite sides of the two mounting blocks, respectively.

[0006] Preferably, the rod placement assembly includes an arched seat, on the top surface of which a material placement plate is fixedly installed. The front side of the material placement plate has a groove, and multiple bottom rollers are rotatably installed on the bottom surface of the groove.

[0007] Preferably, round rods are movably inserted into the middle of both sides of the material placement plate, and rotating seats are fixedly installed at one end of each round rod located in the groove.

[0008] Preferably, multiple side rollers are rotatably mounted on the inner sides of both rotating seats, and cylinders are fixedly mounted on the top of both sides of the material placement plate. One end of the piston rod of each of the two cylinders is fixedly connected to the top of the outer side of the two rotating seats.

[0009] Preferably, the support is fixedly installed in the middle of the top surface of the mounting plate, and a plurality of the arched seats are fixedly installed on the top surface of the mounting plate.

[0010] Preferably, a toothed ring is fixedly sleeved on the front of the outer side of the rotating ring, and the toothed plate is engaged with the toothed ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This tapered cement pole quality inspection device uses a linear motor to drive a toothed plate, which in turn drives a rotating ring, a CCD camera, and a flaw detector to rotate 360°. This eliminates the need for manual adjustment of the inspection angle, effectively reducing the inspection time for a single tapered pole. Furthermore, it eliminates the need to control the rotation of the tapered pole, ensuring comprehensive inspection of the tapered cement pole while reducing the inspection difficulty. Simultaneously, the CCD camera and flaw detector work in sync, enabling simultaneous inspection of surface defects and internal structures, avoiding efficiency losses caused by process splitting. 2. The side rollers of the rod-setting assembly can adaptively adjust the spacing via cylinders to accommodate tapered cement rods of various diameters. The bottom roller facilitates the movement of the rod along its length, enabling full-length inspection. Simultaneously, multiple sets of rod-setting assemblies work together to clamp the rod, preventing it from rolling and shifting during inspection and improving inspection efficiency.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1-4 As shown, this utility model provides a technical solution: the detection table assembly 1 serves as the basic support structure of the device, and the detection table assembly 1 includes a mounting plate 101, a linear motor 102, a connecting bent rod 103, and a toothed plate 104. The mounting plate 101 is a rectangular flat plate, and its top surface is used to mount the detection component 2 and the rod placement component 3. The linear motor 102 is fixedly mounted on the back center of the mounting plate 101 by bolts, and its slider can reciprocate in the vertical direction; The connecting rod 103 is an L-shaped stainless steel rod, one end of which is fixed to the back of the slider of the linear motor 102 by welding, and the other end is connected to the toothed plate 104 by bolts. The toothed plate 104 is used to drive the rotating ring 204 to rotate. The detection assembly 2, used for simultaneously detecting surface defects and internal flaws in tapered cement poles, includes a support 201, an outer ring 202, a rotating ring 204, a gear ring 205, a mounting block 206, a CCD camera 207, and a flaw detection head 208. When the linear motor 102 drives the toothed plate 104 to move, it can drive the toothed ring 205 and the rotating ring 204 to rotate synchronously. The two mounting blocks 206 are rectangular aluminum alloy blocks, and the mounting blocks 206 are symmetrical and fixed to the inner ring surface of the rotating ring 204 by bolts; The CCD camera 207, model MV-CE050-30GM (industrial grade), with a resolution of 5 megapixels, is fixed to the inside of one of the mounting blocks 206 by bolts, with the lens facing the center, and is used to capture images of the pole surface to identify defects such as cracks and exposed ribs. The flaw detector 208 can be an ultrasonic flaw detector with a frequency of 2.5-5MHz. It is fixed to the inside of another mounting block 206 by bolts, with the probe facing the center. It is used to detect problems such as voids and density inside the rod. The diameter-gradient structure is used to stably support and adapt to the tapered cement pole. The pole placement assembly 3 is evenly arranged in 5-7 groups from one side to the other along the top surface of the mounting plate 101. Each group includes an arched seat 301, a material placement plate 302, a bottom roller 303, a round rod 304, a rotating seat 305, a side roller 306, and a cylinder 307. The arched seat 301 is a steel structure, with its bottom fixed to the top surface of the mounting plate 101 by bolts, and its top welded to the material placement plate 302. Three to four bottom rollers 303 are rotatably mounted on the bottom surface of the groove via bearings. The bottom rollers 303 can rotate, which facilitates pushing the cement pole to move along the length direction. The round rod 304 is a cylindrical stainless steel rod that is movably inserted into the middle of the two sides of the material placement plate 302; The rotating seat 305 is a U-shaped steel structure, which is welded to one end of the round rod 304 located in the groove. Two to three side rollers 306 are rotatably installed on its inner side through bearings. The side rollers 306 can rotate and limit the two sides of the cement rod, while also facilitating the movement of the cement rod. The cylinder 307 is fixed to the top of both sides of the material plate 302 by bolts. One end of its piston rod is fixedly connected to the top of the outer side of the rotating seat 305 by bolts. When the cylinder 307 extends or retracts, it can push the rotating seat 305 and the side roller 306 closer to or away from the cement rod, so as to achieve clamping and positioning of tapered rods of different diameters.

[0016] The linear motor 102 is an LS-130 type (80mm stroke, 500N rated thrust), which is fixed to the back of the mounting plate 101 by 4 M8 bolts; Place the conical cement rod to be tested on the bottom roller 303 of the rod placement assembly 3, start the cylinder 307, and push the side roller 306 toward the rod body until the side roller 306 is in contact with the surface of the rod body; Inspection preparation: Connect the CCD camera 207 and the flaw detector 208 to the external terminal (computer), adjust the inspection parameters, the exposure time of the CCD camera 207 is 10-20ms, and the coupling agent coating thickness of the flaw detector is 0.5-1mm. Synchronous detection: The linear motor 102 is started, and its slider drives the toothed plate 104 to move back and forth. The toothed ring 205 drives the rotating ring 204 to rotate. The CCD camera 207 captures images of the pole surface in real time, and the flaw detector 208 simultaneously emits ultrasonic waves to detect the internal structure. At the same time, the cement pole is slowly pushed manually or by an external pushing device to move along the bottom roller 303 to achieve full-length detection of the pole. Data processing: The external terminal receives image data from the CCD camera 207 and ultrasonic data from the flaw detector head 208. It identifies defects such as cracks and exposed reinforcement through image recognition algorithms, determines the location and size of internal cavities through waveform analysis, and generates an inspection report.
