[0032] The cleaning tank 6 is provided with a pipe clamping mechanism 10 for clamping the pipe fittings 4 on the pipe rack when the pipe rack 1 is hoisted into the cleaning tank. A movable pipe connection device is provided at one end of the cleaning tank. The movable pipe connection device includes a movable platform and a pipe connection part 11 that moves with the movable platform. The moving direction of the movable platform corresponds to the axial direction of the pipe fittings in the cleaning tank. The pipe connection part is fixedly provided with pipe sealing joints 1101 corresponding to one end of each pipe fitting on the pipe rack in the cleaning tank. Each pipe sealing joint merges and connects to an external cleaning pipeline. When the pipe clamping mechanism clamps the pipe fitting and the movable platform drives the pipe connection part to move to one end, the pipe sealing joint of the pipe connection part is plugged into the pipe end of the corresponding pipe fitting on the pipe rack to form a sealed pipe connection. When the movable platform drives the pipe connection part to move to the other end, the pipe sealing joint of the pipe connection part is separated from the pipe end of the corresponding pipe fitting. Figure 5-Figure 8 As shown, the pipe clamping mechanism includes clamping components distributed on both sides of the pipe fittings in the cleaning tank, each clamping component includes an electric cylinder 1002, a roller shaft 1003, a clamping wheel 1004, and a synchronous gear 1005, wherein the synchronous gear is axially connected and fixed to the lower end of the roller shaft and is rotatably positioned at the bottom of the cleaning tank, and two synchronous gears in the two clamping components are meshed to form synchronous rotation, the top of the roller shaft is rotatably positioned on the bracket plate 1001, the bracket plate is fixed to the top of the cleaning tank, and the roller shaft is axially connected and fixed with an eccentric clamping wheel, that is, the wheel of the clamping wheel The axis of the shaft and the roller shaft are eccentrically arranged, and the wheel axle 10041 of the clamping wheel passes through the arc-shaped sliding hole 1006 on the top of the bracket plate and is hinged to one end of the push rod of the electric cylinder. The arc-shaped sliding hole adapts to the eccentric swing of the clamping wheel relative to the roller shaft, and the cylinder seat end of the electric cylinder is rotated and positioned on the bracket plate; in the initial state, a clamping space for placing the pipe fitting is formed between the clamping wheels in the two clamping assemblies. When the electric cylinders of the two clamping assemblies push the push rod to drive the clamping wheels and the roller shaft to rotate, the clamping wheels on both sides rotate synchronously in opposite directions and clamp the pipe fitting relatively.

[0033] The mobile platform includes a third electric trolley 12 and an electric lifting bracket 13. The third electric trolley is horizontally limited and movable. The lifting part of the electric lifting bracket is connected to the pipe connection part 11, and the bracket part of the electric lifting bracket is fixed to the third electric trolley. When the lifting part of the electric lifting bracket is lowered into place, the pipe sealing joint 1101 of the pipe connection part is opposite to the pipe end of the pipe fitting 4 in the cleaning tank 6. When the lifting part of the electric lifting bracket is raised into place, the pipe connection part is out of the cleaning tank.

[0034] like Figure 2 As shown, the pipe rack 1 can also be configured with pipe slots 102 vertically spaced on both sides, and loading mechanisms are provided on both sides of the corresponding loading station, and unloading mechanisms are provided on both sides of the unloading station, and the moving range of the first electric trolley 5 and the second electric trolley 9 includes an intermediate station, and the intermediate station corresponds to the lifting station of the pipe rack. Based on this solution, Figure 9-11As shown, the scheme of the pipe clamping mechanism in the cleaning tank is changed to: the pipe clamping mechanism includes a left clamping deformation block 1007, a middle clamping block 1008 and a right clamping deformation block 1009, and one end of the left clamping deformation block, the middle clamping block and the right clamping deformation block are connected to the pipe connection part 11 of the movable pipe connection device, and the left clamping deformation block after connection is located on one side of 6 of the cleaning tank, the right clamping deformation block is located on the other side of the cleaning tank, and the middle clamping block is located in the middle position of the pipe fittings 4 on both sides of the built-in pipe rack in the cleaning tank, and the other ends of the left clamping deformation block and the right clamping deformation block are fixed to the corresponding side in the cleaning tank. When the pipe rack is placed in the cleaning tank and the mobile pipe connection device drives the pipe connection part to move toward the end of the pipe fitting, the middle clamping block enters the middle position of the pipe fittings on both sides of the pipe rack and contacts the pipe fittings on both sides, and the left clamping deformation block and the right clamping deformation block are pushed by the pipe connection part to form a convex deformation toward the middle clamping block and clamp the pipe fittings on both sides of the pipe rack, and the clamping state of the pipe fitting precedes the pipe sealing joint 1101 of the pipe connection part being plugged in to seal the end of the pipe fitting, or the clamping state of the pipe fitting is synchronized with the plugging of the pipe sealing joint of the pipe connection part to seal the end of the pipe fitting.

[0035] Furthermore, the cleaning equipment includes a purge tank with the same structure as the cleaning tank 6, and the purge tank and the cleaning tank are arranged side by side in the width direction. The purge tank is provided with a pipe clamping mechanism and a movable pipe connecting device with the same structure as those in the cleaning tank. The cleaning pipeline connected to the pipe connecting part 11 of the movable pipe connecting device is connected to an external high-pressure air pump, and air is supplied to the pipe fitting through the high-pressure air pump, thereby realizing the purge operation of the inner wall of the pipe and realizing rapid drying of the inner wall of the pipe.

[0036] In order to improve the effect of blowing and drying, the inner wall of the above-mentioned purge tank is provided with a heating plate for heating the outer wall of the pipe fittings on the pipe rack, and the bottom of the purge tank is provided with a drain port and an external drain pump, so as to dry the pipe fittings on the one hand and discharge the liquid in the purge tank in time on the other hand.

[0037] In addition to the above-mentioned scheme structure of the purge slot, the unloading chain row 7 can also be driven by a stepper motor, and the unloading chain row is driven to the position of the pipe 4 supported by the pipe support frame 201 at the top as a pipe processing station. For example, the pipe processing station is a pipe inner wall drying device, and the pipe inner wall drying device is provided with a non-contact high-pressure air nozzle with a pipe port, and the high-pressure air nozzle is externally connected to a high-pressure air pump, that is, the non-contact high-pressure air nozzle is used to blow air to the inner wall of the pipe to achieve the operation of drying the inner wall of the pipe. For another example, the pipe processing station is a device that combines the cleanliness detection and drying of the inner wall of the pipe, and a sponge ball machine is used. The method of translation docking is used between the pipe port to achieve pipe connection. After the pipe connection, the sponge ball machine is used to send sponge balls into the pipe, and the sponge balls are collected at the end of the pipe. The cleanliness of the sponge balls is checked to judge the cleanliness of the pipe, and the sponge balls form a scrubbing and drying function on the inner wall of the pipe. Of course, the pipe processing station is not limited to the above, and other existing equipment can also be used to achieve the corresponding pipe processing function.

[0038] A circulation pump 15 is arranged in the external cleaning pipeline where the pipe sealing joints 1101 of the pipe connection part 11 in the cleaning tank 6 merge, and the liquid inlet of the circulation pump is connected to the cleaning tank, so as to realize the circulation cleaning of the inner wall of the pipe in the cleaning tank.

[0039] The working method of the trough type pipe cleaning hoisting and feeding mechanism is as follows: the pipes 4 to be cleaned are placed obliquely on the support platform 3 of the material rack to be cleaned, the pipe rack 1 is first hoisted by a crane and placed on the first electric trolley 5 of the loading station, the loading chain row 2 is turned on, and the pipes enter the loading chain row one by one and are transmitted to the pipe support frame 201 at the top until a row of vertical pipe supports is formed on one side of the loading chain row. At this time, the loading chain row transmission is stopped, and the first electric trolley of the loading station drives the pipe rack to move into position in the direction of the loading chain row. After moving into position, each pipe slot 102 of the pipe rack corresponds vertically to the pipe supported by the loading chain row, and each pipe slot is located below the corresponding pipe. The loading chain row is controlled to rotate one more station, and the pipes of the loading chain row fall into the pipe slots of the pipe rack accordingly, and the electric trolley drives the pipe rack to separate from the loading chain row and reach the lifting station of the loading station. The pipe rack is suspended by a crane and enters the corresponding cleaning tank 6. The pipe fittings on the pipe rack are clamped by controlling the pipe clamping mechanism 10. After clamping, the third electric trolley 12 of the mobile pipe connection device is controlled to drive the pipe connection part 11 to move toward the pipe fitting port until the pipe sealing joint 1101 of the pipe connection part is plugged into the end of the pipe fitting to form a sealed pipe connection. The ultrasonic vibration plate 601 in the cleaning tank and the external circulation pump 15 are turned on. The ultrasonic vibration plate mainly cleans the outer wall of the pipe fitting, and the circulation pump circulates the cleaning liquid in the cleaning tank into the pipe fitting to clean the inner wall of the pipe fitting. After one cleaning is completed, the pipe rack is lifted out of the cleaning tank by the crane and transferred to the next cleaning tank for repeated cleaning, or lifted out and transferred to the second electric trolley 9 of the unloading station, and the second electric trolley drives the pipe rack to move to the unloading chain row 7 in the direction of the unloading chain row. After moving into position, each pipe slot of the pipe rack corresponds to the vertical pipe support frame on one side of the unloading chain row. The unloading chain row is turned on and rotated one station, and the pipe fittings on the pipe rack enter the pipe support frame on one side of the unloading chain row. After that, the second electric trolley drives the pipe rack to separate from the unloading chain row and reach the lifting station of the unloading station. The unloading chain row continues to drive and transports the pipe fittings on the pipe support frame to the top of the unloading chain row. The pipe fittings are self-weighted and fall off the pipe support frame and enter the storage rack 8 along the unloading guide plate 801. After completing the above work, the crane suspends the pipe rack and resets it to the loading station, and the cleaning operation of the next group of pipe fittings can be carried out.
