Description

Technical Field

[0001] The present invention relates to the field of cable trough detection, and more specifically, to a quality detection device for a glass fiber reinforced plastic cable trough. Background Art

[0002] FRP cable trough (also known as FRP cable tray) is a cable laying device with glass fiber reinforced plastic as the main material. Its background technology stems from the shortcomings of traditional metal and concrete cable troughs in durability, corrosion resistance and installation efficiency. Traditional metal cable troughs are easily corroded by moisture, acid and alkali environments, resulting in reduced structural strength and high maintenance costs; concrete products have defects such as heavy weight, poor seismic resistance, and long construction period. With the increasing requirements for cable protection systems in the fields of electricity, communications, rail transit, etc., FRP materials have gradually become an alternative due to their light weight, high strength, corrosion resistance, flame retardant insulation, and aging resistance. In order to know whether the expected performance requirements are met during the production of FRP cable troughs, a number of tests such as raw material testing, appearance and size testing, mechanical property testing, corrosion resistance testing, and flame retardancy testing will be carried out;

[0003] Mechanical properties are the core indicators of FRP cable trays, which directly determine their load-bearing capacity, deformation resistance and service life. Bending strength test and bearing capacity test are the main tests for detecting mechanical properties. The existing method uses a purchased universal universal material testing machine to test bending strength and bearing capacity.

[0004] The device uses a disc as the contact part for applying pressure, while the cable trough is of a certain length and is subject to a wide range of forces during use. Therefore, there is a significant difference between a small-scale local test and the actual use environment. Secondly, the device requires manual loading and unloading, which is inefficient and difficult to integrate, making it difficult to meet the needs of automated production.

[0005] In order to solve the above problems, this application proposes a fiberglass reinforced plastic cable trough quality detection device. Summary of the Invention

[0006] The purpose of the present invention is to provide a fiberglass reinforced plastic cable trough quality detection device, which solves the problems in the prior art by simulating actual adaptation environment detection and production line continuous detection.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] like Figure 1 - Figure 7 As shown: A glass fiber reinforced plastic cable trough quality inspection equipment, including a conveying bracket 1 and a detection bracket 2, the detection bracket 2 is higher than the conveying bracket 1 and is located in the middle of its upper end, a flat plate 21 is fixed on the top of the detection bracket 2, and a conveying mechanism 3 is installed on the conveying bracket 1, the conveying mechanism 3 includes a loading area 31, a detection area 32 and a unloading area 33, the loading area 31 and the detection area 32 are arranged flush, the loading area 31, the detection area 32 and the unloading area 33 are all provided with a mounting seat, a conveyor belt and a motor, the mounting seat on the loading area 31 and the unloading area 33 is fixed to the conveying bracket 1, the mounting seat in the detection area 32 is fixed to the guide rod 43 on the lifting component 4, and there is a transmission roller on the mounting seat, and the conveyor belt is located outside the transmission roller and is transported by the drive of the motor.

[0034] Furthermore, a hanger 6 for suspending the cable trough 10 is fixed at the lower end of the flat plate 21. The hangers 6 are two symmetrical ones that support the cable trough 10 from both ends of the bottom. The hanger 6 as a whole adopts the same angle iron structure as the existing suspension method, and is formed by welding or bolt connection. Then, it is installed at the bottom of the flat plate 21 by bolts. The flat plate 21 here is equivalent to the top of the wall. The detection environment in this embodiment is consistent with the actual installation environment, thereby making the detection data more reliable.

[0035] Furthermore, the upper end of the detection area 32 is the conveying station of the cable trough 10, and the hanger 6 is the detection station of the cable trough 10. The detection area 32 is installed on the conveying bracket 1 in a liftable manner through the lifting component 4, and is used to switch the cable trough 10 between the detection station and the conveying station. When the lifting component 4 is at the top, the overall upper surface of the conveying mechanism 3 is flush for the conveying of the cable trough 10. When the lifting component 4 moves down, the cable trough 10 can be placed on the hanger 6 for testing. In order to free up the deformation space of the cable trough 10 during pressure testing, the lifting component 4 will drive the detection area 32 to continue to move down a certain height to avoid the cable trough 10 from bending and offsetting the detection area 32, affecting the detection accuracy.

[0036] Furthermore, the lifting component 4 includes a base plate 41 horizontally fixed on the conveying bracket 1 and a lifting cylinder 42 fixed to the bottom of the base plate 41, and also includes a guide rod 43 fixed on the mounting seat at the bottom of the detection area 32. The guide rod 43 also slides with the linear sleeve 411 to ensure stable lifting of the detection area 32. The guide rod 43 and the linear sleeve 411 are provided with multiple groups arranged symmetrically. The guide rod 43 passes through the bottom of the linear sleeve 411 and is provided with a limit plate to ensure that the detection area 32 is highly consistent with the loading area 31 and the detection area 32 after the lifting component 4 rises. The output end of the lifting cylinder 42 passes through the base plate 41 upward and is fixed to the bottom of the detection area 32.

[0037] Furthermore, the conveying bracket 1 is equipped with baffles 8 located at both ends of the detection area 32 and can be raised and lowered. The distance between the two baffles 8 is adapted to the length of the cable trough 10, and is used to block the two ends of the cable trough 10 during detection to prevent displacement after pressure is applied. The baffle 8 slides vertically in the baffle seat 81, and the baffle seat 81 is fixed to the side of the loading and unloading area of the conveying mechanism 3. When the baffle 8 rises, it is higher than the conveying mechanism 3, and when it falls, it is lower than the height of the upper surface of the conveying mechanism 3.

[0038] Furthermore, a transmission mechanism 5 is provided between the lifting component 4 and the transmission mechanism 5, which utilizes the power of the lifting cylinder 42 to drive the baffle 8. The transmission mechanism 5 includes a support base 51 fixed on the base plate 41, and a rotating gear 52 is provided on the support base 51. An active tooth plate 53 is fixed on the side of the detection area 32 and meshes with the gear 52. A driven tooth plate 54 is fixed on the baffle 8 and meshes with the active tooth plate 53. The gear 52 and the driven tooth plate 54 are both vertically arranged and matched on both sides of the gear 52 in a parallel manner. The transmission mechanism 5 is provided with two groups of baffles 8 at both ends.

[0039] Furthermore, a detection mechanism 7 located directly above the detection area 32 is installed on the flat plate 21. The detection mechanism 7 includes a pressure plate 73 arranged along the length direction of the cable trough 10. The bottom of the pressure plate 73 is provided with an arc-shaped surface in contact with the cable trough 10. The cable trough 10 with both length and curvature can better fit the pressure curve after the cables are arranged. The detection mechanism 7 also includes a detection cylinder 71 fixed on the flat plate 21 and a sensor 72 installed at the output end of the detection cylinder 71. The pressure plate 73 is installed at the lower end of the sensor 72. The sensor 72 is a pressure sensor, and the upper and lower ends are fixed to the output shaft of the detection cylinder 71 and the pressure plate 73 by threads.

[0040] Furthermore, a control cabinet 9 is installed on the flat plate 21. The motor, lifting cylinder 42, detection cylinder 71 and sensor 72 in the conveying mechanism 3 are all telecommunication-connected to the control cabinet 9. The control cabinet 9 has a signal receiving and sending function, and can collect and record the data of the sensor 72. Then, the computer equipment is used to determine whether the cable trough 10 meets the standards. If it meets the standards, subsequent inspections will continue. If it does not meet the standards, it will be eliminated.

[0041] It can be understood that the motors on the loading area 31, the detection area 32, and the unloading area 33 are started by the same switch. In the conveying state, the top surfaces of the three are flush, and the cable trough 10 is conveyed from the loading area 31 to the detection area 32 and stops. At this time, the lifting component 4 drives the detection area 32 to move downward, and the cable trough 10 is placed on the hanger 6 and enters the detection station. The detection area 32 continues to move downward to leave bending space during the inspection. During the downward movement of the lifting component 4, the baffle 8 is driven by the transmission mechanism 5 to move upward to block the two ends of the cable trough 10, and then the detection mechanism 7 presses down to perform force performance detection;

[0042] After the detection, the detection mechanism 7 moves up and resets, and the lifting component 4 drives the detection area 32 and the cable trough 10 to move up to the conveying station. The baffle 8 moves down after the transmission mechanism 5 acts, and the conveying mechanism 3 starts and conveys the cable trough 10 backward.

[0043] In the description of the present invention, unless otherwise specified, “plurality” means two or more; it should be understood that terms such as “opening”, “upper”, “lower”, “thickness”, “top”, “middle”, “length”, “inner”, “around”, etc., indicating orientation or positional relationship, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0044] 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 scope of protection of the present invention.
