Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a flexible hose delivery device for inspecting heat exchanger pipelines. Background Technology

[0002] When existing heat exchangers are damaged, it is difficult to determine which one is damaged due to the long and densely packed heat exchange tubes. Furthermore, the heat exchange tubes are welded to the flanges of the heat exchanger, making it difficult to disassemble and inspect them. Overall inspection is quite difficult. The control system of the eddy current instrument is electrically connected to a sensor. The conductive sleeve between the sensor and the control system is covered with a long flexible tube. During inspection, the sensor is manually inserted into the heat exchange tube, and then the flexible tube is continuously pushed into the heat exchange tube. As long as the length of the flexible tube is long enough, the entire interior of the heat exchange tube can be inspected.

[0003] A search of existing Chinese patent technology reveals a device for "a pipeline eddy current detection device" with publication number "CN214503451U". This device can shield the line interface to prevent dust and other impurities from the external environment from entering the line interface when it is not in use, thus affecting the subsequent use of the line interface. However, the hose reeling operation is complicated during the use of this device, which affects work efficiency and increases the labor intensity of the staff. Utility Model Content

[0004] Therefore, it is necessary to address the problem that the hose reeling operation is cumbersome during use, affecting work efficiency and increasing the labor intensity of workers. A hose conveying device for heat exchanger pipeline inspection is provided, comprising: two bonding plates, with two connecting rods fixedly connected between the two bonding plates, the connecting rods being staggered with the bonding plates; an inspection conveying mechanism installed on one side of the bonding plates; wherein the inspection conveying mechanism includes a conveying component installed on one side of the two bonding plates, a receiving component disposed below the conveying component, and a servo motor connected to one end of the receiving component.

[0005] In one embodiment, the conveying assembly includes two upper side plates respectively fixedly connected to one side of the bonding plate, and two rotating rods rotatably connected between the two upper side plates. Both ends of the rotating rods extend to the other side of the upper side plates, and airbags are rotatably connected to the surface of the rotating rods.

[0006] In one embodiment, the storage assembly includes a lower side plate fixedly connected to one side of the bonding plate, a rotating shaft rotatably connected between the lower side plates, the lower side plates being located below the upper side plate, a winding seat fixedly connected to the surface of the rotating shaft, and one side of the rotating shaft extending through to the side of the lower side plate away from the servo motor.

[0007] In one embodiment, rubber rings are provided at both ends of the airbag, with the surfaces of adjacent rubber rings abutting each other. The rubber rings cause the two rotating rods to rotate synchronously but in opposite directions, thereby causing the two airbags to transport and compress the tube.

[0008] In one embodiment, a first pulley is fixedly connected to the surface of the lower rotating rod, and the first pulley is located on the side of the upper side plate away from the servo motor.

[0009] In one embodiment, a plurality of rubber strips are fixedly connected to the surface of the airbag, and the rubber strips are distributed in a ring shape along the surface of the airbag. The surface of the airbag can deform, and in conjunction with the rubber strips, it can increase the contact area with the tube body, assisting in moving the tube body.

[0010] In one embodiment, a one-way bearing is fixedly connected to the surface of the rotating shaft, and the one-way bearing is located on the side of the lower plate away from the servo motor. The servo motor drives the rotating shaft to rotate, and when the rotating shaft rotates, it drives the take-up seat to rotate synchronously with the one-way bearing.

[0011] In one embodiment, a second pulley is fixedly connected to the surface of the one-way bearing, and a transmission belt is fitted onto the surface of the second pulley. The one-way bearing only drives the second pulley to rotate clockwise, which in turn drives the first pulley to rotate synchronously via the transmission belt.

[0012] Beneficial effects

[0013] The aforementioned hose delivery device for heat exchanger pipeline inspection drives the first pulley to rotate via a transmission belt, which in turn drives the lower rotating rod to rotate. The rubber ring causes the two rotating rods to rotate synchronously but in opposite directions, which in turn causes the two airbags to deliver and compress the tube. Since the surface of the airbags can deform and, together with the rubber strip, can increase the contact area with the tube, it assists in moving the tube, improving the convenience of operation for the staff, ensuring work efficiency, and reducing the labor intensity of the staff.

[0014] The servo motor driven by the storage component drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the take-up unit and the one-way bearing to rotate synchronously. Since the one-way bearing only drives the second pulley to rotate when it rotates clockwise, the first pulley is driven to rotate synchronously through the transmission belt. When it rotates counterclockwise, the take-up unit moves the tube body, and the take-up unit can quickly store the tube body. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The following is combined Figures 1-5 This invention describes a flexible hose delivery device for inspecting heat exchanger pipes.

[0025] In one embodiment, a hose conveying device for heat exchanger pipeline inspection includes: two bonding plates 1, with two connecting rods 2 fixedly connected between the two bonding plates 1, the connecting rods 2 and the bonding plates 1 being staggered; an inspection conveying mechanism 3, which is installed on one side of the bonding plates 1; wherein, the inspection conveying mechanism 3 includes a conveying component 31 installed on one side of the two bonding plates 1, a receiving component 32 is provided below the conveying component 31, and one end of the receiving component 32 is connected to a servo motor 33;

[0026] It should be noted that the eddy current testing device is a non-destructive testing device based on the principle of electromagnetic induction, used to detect surface and near-surface defects in conductive materials, and to measure material properties such as conductivity, magnetic permeability, and thickness. Its core principle is to assess the integrity or physical properties of materials by inducing changes in eddy currents. Existing methods for inserting and pulling out hoses are all done manually, resulting in relatively messy hoses during use. Furthermore, winding the hoses is done by simply wrapping them around the hand and tying them with a rope after all the bends are completed, making it inconvenient to use. This device connects the hose to the inside of the winding seat 323 for easier winding and unwinding.

[0027] like Figure 1-4 As shown, the conveying assembly 31 includes two upper side plates 311 that are fixedly connected to one side of the bonding plate 1. Two rotating rods 312 are rotatably connected between the two upper side plates 311. Both ends of the rotating rods 312 extend to the other side of the upper side plates 311. An airbag 314 is rotatably connected to the surface of the rotating rod 312. Rubber rings 313 are provided at both ends of the airbag 314. The surfaces of adjacent rubber rings 313 abut against each other. A first pulley 315 is fixedly connected to the surface of the lower rotating rod 312. The first pulley 315 is located on the side of the upper side plate 311 away from the servo motor 33. Multiple rubber strips 316 are fixedly connected to the surface of the airbag 314. The multiple rubber strips 316 are distributed in a ring shape along the surface of the airbag 314.

[0028] In this embodiment, the device drives the first pulley 315 to rotate via the transmission belt 325, which in turn drives the lower rotating rod 312 to rotate. The rubber ring 313 causes the two rotating rods 312 to rotate synchronously and in opposite directions, which in turn causes the two airbags 314 to transport and compress the tube. Since the surface of the airbag 314 can be deformed and it works with the rubber strip 316 to increase the contact area with the tube, it assists in moving the tube.

[0029] like Figure 2 , Figure 3 and Figure 5As shown, the storage assembly 32 includes a lower side plate 321 fixedly connected to one side of the bonding plate 1. A rotating shaft 322 is rotatably connected between the lower side plates 321. The lower side plate 321 is located below the upper side plate 311. A winding seat 323 is fixedly connected to the surface of the rotating shaft 322. One side of the rotating shaft 322 extends through to the side of the lower side plate 321 away from the servo motor 33. A one-way bearing 326 is fixedly connected to the surface of the rotating shaft 322. The one-way bearing 326 is located on the side of the lower side plate 321 away from the servo motor 33. A second pulley 324 is fixedly connected to the surface of the one-way bearing 326. A transmission belt 325 is sleeved on the surface of the second pulley 324.

[0030] In this embodiment, the servo motor 33 drives the rotating shaft 322 to rotate. When the rotating shaft 322 rotates, it drives the take-up holder 323 and the one-way bearing 326 to rotate synchronously. Since the one-way bearing 326 only drives the second pulley 324 to rotate clockwise, the first pulley 315 is driven to rotate synchronously through the transmission belt 325. When it rotates counterclockwise, the take-up holder 323 drives the tube to move. The take-up holder 323 can quickly retract the tube.

[0031] Working principle: The servo motor 33 drives the rotating shaft 322 to rotate. When the rotating shaft 322 rotates, it drives the take-up seat 323 and the one-way bearing 326 to rotate synchronously. The one-way bearing 326 only drives the second pulley 324 to rotate when rotating clockwise. The transmission belt 325 drives the first pulley 315 to rotate synchronously. When rotating counterclockwise, the take-up seat 323 drives the tube to move. The take-up seat 323 quickly takes in the tube. The transmission belt 325 drives the first pulley 315 to rotate. The first pulley 315 drives the lower rotating rod 312 to rotate. The rubber ring 313 and the two rotating rods 312 rotate synchronously in opposite directions. The two airbags 314 transport and compress the tube. The surface of the airbag 314 deforms, which, together with the rubber strip 316, increases the contact area with the tube and assists in moving the tube.

[0032] It should be noted that the servo motor 33 and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. At the same time, the servo motor 33 can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
