Description

Technical Field

[0001] This utility model relates to the field of pickling and passivation of PP pipes, specifically to anti-pollution hoisting equipment for multi-stage process pools. Background Technology

[0002] As my country's manufacturing industry transforms towards high-end and green development, the demand for PP pipes in petrochemical, food processing, and medical device industries continues to grow. Pickling and passivation, as the core surface treatment process for PP pipes, directly affects the product's corrosion resistance and service life. Current production processes generally utilize overhead cranes with slings or semi-automatic hangers with simple limiting mechanisms to fix the pipes, which are then manually immersed in different process tanks to sequentially complete degreasing, pickling, rinsing, passivation, and drying. However, existing equipment still has some problems and shortcomings in actual use. First, existing hoisting equipment requires manual control, resulting in poor positioning accuracy, low work efficiency, and high safety risks. Second, during material lifting and unloading, pipes may slip due to vibration or other reasons, causing production accidents. Furthermore, when draining the treatment liquid from the steel pipe, it is often not completely drained, leading to cross-contamination of the tank liquids, increasing treatment liquid loss and wastewater costs, and affecting subsequent processes. Meanwhile, in the existing hoisting equipment, the material pipe is detached from the liquid surface in a horizontal position during the lifting process, and a large amount of liquid will accumulate in the material pipe. This will increase the resistance during lifting, and if the impact is large, it may even cause the material pipe to slip.

[0003] Currently, a utility model patent with publication number CN222411856U discloses a suspended basket for zinc removal from steel wire ropes, including a basket body. The basket body includes a fence and a base plate disposed at the bottom of the fence. The top side wall of the fence has buckle holes for fastening the suspension rope. The base plate includes several parallel support plates, with a gap between each pair of adjacent support plates for the flow of pickling solution. This application has the effect of improving the zinc removal efficiency of steel wire ropes.

[0004] As can be seen from the above-disclosed technical content, as existing technology, the utility model with announcement number CN222411856U uses a hoisting rope to lift the basket body into the pickling tank. During the process of the basket sinking, the pickling solution in the pickling tank flows into the basket body from the top opening of the fence and the gaps between several support plates, so that the steel wire rope with zinc coating is fully immersed in the pickling solution, which can quickly remove the zinc coating on the steel wire rope. However, this patent is mainly aimed at the zinc removal treatment of steel wire rope and cannot solve the problem of cross-contamination of tank solutions, which increases the loss of treatment solution and wastewater costs. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a pollution prevention hoisting device suitable for multi-stage process tanks, which can effectively reduce the resistance when lifting materials through the feed pipe and effectively prevent cross-contamination of the tank liquids.

[0006] To achieve the above objectives, this utility model is applicable to a pollution prevention hoisting equipment for multi-stage process pools, including a track and a trolley. The two tracks are arranged in parallel, and the trolley moves back and forth on the tracks. A steel pipe lifting and cleaning assembly is fixedly installed on the lower part of the trolley via a bracket. Two lifting mechanisms of the steel pipe lifting and cleaning assembly are respectively installed on both sides of the lower part of the trolley, and the lifting mechanisms are hinged to both ends of the material frame via hinge shafts. A slide rail for a water receiving tray assembly is fixedly installed on the lower part of the trolley via a bracket, and the water receiving tray moves back and forth on the slide rail via a slider driven by a motor. Anti-collision components are fixedly installed on both sides of the trolley.

[0007] In addition, the anti-pollution hoisting equipment for multi-stage process tanks proposed in the above embodiments of this utility model may also have the following additional technical features: As a further improvement of this utility model, the anti-collision component includes a collision sensing block, a limit switch, a collision tube, a spring, and a collar. The limit switch is fixedly installed on the surface of the vehicle. The collision sensing block is cylindrical with a groove around the center. The groove has slopes on both sides. The telescopic end of the limit switch extends into the groove of the collision sensing block. Two symmetrically arranged collision tubes are movably installed in the collar. The collar is fixedly installed on the surface of the vehicle. The ends of the collision tubes are fixedly connected to the two ends of the collision sensing block. A spring is fitted on the collision tube between the collar and the collision sensing block.

[0008] As a further improvement of this utility model, the water receiving tray of the water receiving tray assembly is movably mounted on the slide rail at both ends by sliders. The slide rail is fixedly mounted on the lower part of the trolley by a bracket. The water receiving tray is equipped with a motor and gears, and the slide rail is equipped with a toothed belt. The water receiving tray assembly is provided with drain pipes at both ends. A drain tray is fixedly installed at the lower outlet of the drain pipe. The drain pipe of the drain tray is connected to the drainage ditch through a pipeline.

[0009] As a further improvement of this utility model, the upper part of the track is provided with a ridge, and the drive unit of the trolley is provided with a clamping wheel.

[0010] As a further improvement of this utility model, the water receiving tray of the water receiving tray assembly is made of PP material.

[0011] By employing the above-described solution, this utility model possesses at least the following advantages: By adding asynchronous lifting mechanisms to both ends of the traditional straight-up-down material frame, the two lifting mechanisms are staggered for a short period during lifting, causing the material frame to enter an inclined state. This allows the tank liquid to drain quickly and the material to transition smoothly when exiting the water, effectively reducing resistance during material lifting. Simultaneously, after lifting the material, the water receiving tray is directly moved to collect water directly below the material frame, allowing the tank liquid to flow along the drain pipe onto the drainage tray, and then drain into the ditch. Since most of the tank liquid has been drained, the remaining small amount is collected by the water receiving tray, effectively preventing cross-contamination. Finally, by adding an anti-collision component that immediately stops the machine upon triggering, equipment safety is ensured. Attached Figure Description

Detailed Implementation

[0013] The following description, in conjunction with the accompanying drawings, describes the pollution prevention hoisting equipment of this utility model applicable to multi-stage process pools.

[0014] In Embodiment 1 of this application, as Figures 1 to 4As shown, this invention (hereinafter referred to as "the invention") is applicable to the anti-pollution hoisting equipment for multi-stage process pools. It includes a track 1 and a trolley 2. The two tracks 1 are arranged in parallel, and the trolley 2 moves back and forth on the tracks 1. A steel pipe lifting and cleaning assembly 3 is fixedly installed on the lower part of the trolley 2 by a bracket. The two lifting mechanisms 31 of the steel pipe lifting and cleaning assembly 3 are respectively installed on both sides of the lower part of the trolley 2. The lifting mechanisms 31 are hinged at both ends of the material frame 33 by hinge shafts 32. The slide rail of the water receiving tray assembly 5 is fixedly installed on the lower part of the trolley 2 by a bracket. The water receiving tray moves back and forth on the slide rail by a slider driven by a motor. Anti-collision components 4 are fixedly installed on both sides of the trolley 2. The water receiving tray of the water receiving tray assembly 5 is movably installed on the slide rail by sliders at both ends. The slide rail is fixedly installed on the lower part of the trolley 2 by a bracket. The water receiving tray is equipped with a motor and gears. The slide rail is equipped with a toothed belt. The water receiving tray assembly 5 has a drain pipe at both ends. A drain pan is fixedly installed at the lower outlet of the drain pipe. The drain pipe of the drain pan is connected to a drainage ditch through a pipeline. Below the material frame 33 is a PP material receiving tray assembly 5. The liquid falling from the material frame 33 is caught in the receiving tray and discharged into the ditch via a drain pipe and drain pan. The PP material receiving tray assembly 5 has translational capability. When the material frame 33 is raised or lowered, the PP material receiving tray moves along the slide rail under the action of a motor, gears, and a toothed belt, aligning the raising and lowering path of the material frame 33. After the material is lifted, the PP material receiving tray returns to its original position below the material frame 33.

[0015] A suspended basket for zinc removal from steel wire ropes (hereinafter referred to as "the patent") with utility model announcement number CN222411856U is used to lift and sink the basket body into the pickling tank by means of a suspension rope. During the sinking process, the pickling solution in the pickling tank flows into the basket body from the top opening of the fence and the gaps between several support plates, so that the steel wire rope with zinc coating is fully immersed in the pickling solution, thereby achieving rapid removal of zinc coating from the steel wire rope. However, the patent mainly focuses on the zinc removal treatment of steel wire ropes and cannot solve the problem of cross-contamination of the tank solution, which increases the loss of treatment solution and wastewater costs. The present invention adds lifting mechanisms 31 that can be raised and lowered asynchronously at both ends of the traditional straight up and down material frame 33. The two lifting mechanisms 31 are staggered for a short period of time during the raising and lowering, so that the material frame 33 enters an inclined state, which allows the tank solution to drain out quickly and the material to transition smoothly when exiting the water, which can effectively reduce the resistance when lifting material from the material pipe. Meanwhile, with the help of the water receiving tray assembly 5 that can be moved horizontally below the material frame 33, after the material is lifted, the water receiving tray can be moved horizontally to the bottom of the material frame 33 to collect water, and the tank liquid can flow along the drain pipe to the drain tray and be discharged into the ditch through the drain tray. Since most of the tank liquid has been drained out, the small amount of remaining tank liquid is received by the water receiving tray, which can effectively prevent cross-contamination of the tank liquid.

[0016] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 5As shown, the anti-collision component 4 includes a collision sensing block 41, a limit switch 42, and a collar 45. The limit switch 42 is fixedly installed on the surface of the vehicle 2. The collision sensing block 41 is cylindrical with a groove around the center. The groove has slopes on both sides. The telescopic end of the limit switch 42 extends into the groove of the collision sensing block 41. Two symmetrically arranged collision tubes 43 are movably installed in the collar 45. The collar 45 is fixedly installed on the surface of the vehicle 2. The ends of the collision tubes 43 are fixedly connected to the two ends of the collision sensing block 41. A spring 44 is fitted on the collision tube 43 between the collar 45 and the collision sensing block 41.

[0017] To further optimize the working efficiency of this application and make the operation of the crane 2 more stable, such as Figure 6 As shown, the upper part of the track 1 is provided with a raised ridge 11, and the drive unit of the trolley 2 is provided with a clamping wheel 21. In order to further improve the service life of the water receiving tray, the water receiving tray of the water receiving tray assembly 5 is made of PP material.

[0018] When used, it is applicable to the installation of anti-pollution hoisting equipment for multi-stage process pools. It can be put into use after connecting the corresponding wiring equipment.

[0019] When this utility model is used, its specific operation is as follows: In use, the two lifting mechanisms 31 of the steel pipe lifting and cleaning assembly 3 simultaneously control the material frame 33 to descend. The staff loads the material frame 33 with materials. Then, the two lifting mechanisms 31 of the steel pipe lifting and cleaning assembly 3 simultaneously control the material frame 33 to rise. The trolley 2 drives the equipment to the first treatment tank. The two lifting mechanisms 31 of the steel pipe lifting and cleaning assembly 3 simultaneously control the material frame 33 to descend, completely immersing the material frame 33 in the treatment tank. After the set time is reached, one of the two lifting mechanisms 31 of the steel pipe lifting and cleaning assembly 3 starts to lift, and the other starts to lift after a short interval, so that the material frame 33 can be tilted and lifted. After being lifted into position, the lifting mechanism 31 that lifted first stops, and the other lifting mechanism 31 that lifted later also stops after the material frame 33 returns to a horizontal state. At this time, it can be ensured that the material in the material frame 33 can smoothly transition when the water is discharged, and the tank liquid can slide down quickly and naturally along the inclined path, which can effectively reduce the resistance when lifting the material in the pipe. Excess tank liquid can fall into the treatment tank. Next, the motor on the water receiving tray of the water receiving tray assembly 5, through gear and toothed belt on the slide rail, moves the water receiving tray horizontally to directly below the material frame 33 to collect the remaining small amount of tank liquid. The tank liquid is discharged into the ditch through the drain pipe and drain tray. Finally, the trolley 2 drives the equipment to the top of the next processing tank. The motor on the water receiving tray of the water receiving tray assembly 5, through gear and toothed belt on the slide rail, moves the water receiving tray horizontally away from directly below the material frame 33, making it easier for the material frame 33 to immerse the material into the processing tank. The drain tray is located outside the material frame 33 and does not affect the lifting and lowering of the material frame 33.

[0020] When the anti-collision component 4 is in use, if a collision occurs, the collision tube 43 will be triggered first. The collision tube 43 will drive the collision sensing block 41 to move. The moving collision sensing block 41 will cause the end of the limit switch 42 to disengage from the annular groove. At the same time as disengaging from the annular groove, the end of the limit switch 42 will be compressed, thereby triggering the limit switch 42. This will cause the equipment controller to receive a signal and control the equipment to stop. When the collision tube 43 is not compressed, the spring 44 will reset the collision tube 43, and the end of the limit switch 42 will re-enter the annular groove of the collision sensing block 41. The limit switch 42, which is no longer triggered by the collision sensing block 41, will reset, and the anti-collision component 4 will return to the standby state.

[0021] In summary, the pollution prevention hoisting equipment for multi-stage process tanks according to this utility model embodiment adds asynchronous lifting mechanisms 31 to both ends of the traditional straight-up-down material frame 33. This allows the two lifting mechanisms 31 to be staggered during lifting, resulting in the material frame 33 being tilted. This allows the tank liquid to drain quickly and the material to transition smoothly when exiting the water, effectively reducing resistance during material lifting. Simultaneously, the movable water receiving tray assembly 5 below the material frame 33 allows the water receiving tray to be moved directly below the material frame 33 after material lifting to collect water. The tank liquid then flows along the drain pipe to the drain pan and is discharged into the ditch. Since most of the tank liquid has been drained, the remaining small amount is collected by the water receiving tray, effectively preventing cross-contamination. Finally, the addition of an anti-collision component 4 ensures immediate shutdown upon triggering, guaranteeing equipment safety.
