Description

Technical Field

[0001] The present invention relates to the technical field of post - galvanizing treatment, and particularly to a post - galvanizing treatment device for insulator fittings. Background Art

[0002] Galvanizing is a common surface anti - corrosion process for insulator fittings. After insulator fittings are galvanized, post - treatment processes such as removing hanging zinc and zinc spines are often accompanied. Traditional post - galvanizing treatment equipment uses a centrifugal zinc - throwing machine. By driving the insulator fittings to rotate at high speed, the hanging zinc and zinc spines formed by galvanizing are thrown off the insulator fittings by centrifugal force. During the high - speed rotation of the insulator fittings, the flow of zinc liquid on the surface is strong, which easily causes the thickness of the galvanized layer to become thinner accordingly, resulting in local corrosion and forming white spots, thus causing quality defects of the insulator fittings. In addition, the centrifugal zinc - throwing machine requires a special fixture. Before zinc - throwing, the insulator fittings need to be raked after galvanizing and then placed on the special fixture for turnover, and the post - galvanizing treatment time of the insulator fittings is long.

[0003] Therefore, the present invention proposes a post - galvanizing treatment device for insulator fittings to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a post - galvanizing treatment device for insulator fittings, which can efficiently remove hanging zinc and zinc spines, ensure the integrity and uniformity of the galvanized layer, and does not require raking and turnover of the insulator fittings, shortening the post - galvanizing treatment cycle.

[0005] To solve the above - mentioned technical problem, the technical solution of the present invention is: A post - galvanizing treatment device for insulator fittings, the innovation of which lies in: including A zinc - vibrating workbench for placing a galvanized rake loaded with insulator fittings; A receiving table located below the zinc - vibrating workbench; The zinc - vibrating workbench is driven by a driving mechanism to be in a first state and a second state; In the first state, the zinc - vibrating workbench is driven by the driving mechanism to move upward to the highest position; In the second state, the zinc - vibrating workbench freely falls from the highest position under the action of gravity and strikes the receiving table below it.

[0006] Further, the driving mechanism includes a rotatable cam; The cam has a closed contour, and the closed contour includes a falling - section curve and a lifting - section curve for pushing the zinc - vibrating workbench to move upward. The lifting - section curve has a head end and a tail end. The distance from the lifting - section curve to the center of rotation of the cam gradually increases from the head end to the tail end. The two ends of the falling - section curve are respectively connected to the tail end and the head end of the lifting - section curve. The cam forms an avoidance space on the side of the falling - section curve away from the lifting - section curve for the zinc - vibrating workbench to freely fall.

[0007] Further, the drop section profile line includes a straight section profile line and an arc section profile line. The two ends of the straight section profile line are the first end and the second end respectively. The first end of the straight section profile line is connected to the tail end of the lifting section profile line. The two ends of the arc section profile line are respectively connected to the second end of the straight section profile line and the head end of the lifting section profile line. The center of the arc section profile line coincides with the rotation center of the cam. The straight section profile line is located in the radial direction of the arc section profile line.

[0008] Further, when the galvanizing table moves to the highest position, the tail end of the lifting section profile line and the rotation center of the cam are on the same vertical line.

[0009] Further, the galvanizing table has a roller that can roll along the lifting section profile line of the cam towards the tail end. The roller is rotatably installed at the bottom of the galvanizing table through a bearing.

[0010] Further, the cam is driven to rotate by a rotary drive. The rotary drive is installed on a base. The cam is connected to the output end of the rotary drive through a rotating shaft. The rotating shaft is installed on the base through two mounting seats. The two mounting seats are installed side by side on the base. The rotating shaft movably passes through the two mounting seats. There are a first enlarged diameter section and a second enlarged diameter section between the two mounting seats on the rotating shaft. The outer diameter of the first enlarged diameter section is larger than that of the second enlarged diameter section. The cam is sleeved on the second enlarged diameter section. A cam limit sleeve is sleeved on the side of the second enlarged diameter section away from the first enlarged diameter section of the cam.

[0011] Further, an avoidance groove for the cam to rotate into is opened between the two mounting seats on the base.

[0012] Further, the receiving table includes a number of receiving sleeves installed on the base. The galvanizing table has a number of guiding mechanisms corresponding to the receiving sleeves one by one. The guiding mechanism includes a guiding rod and a guiding sleeve. The central axis of the guiding rod is vertically arranged inside the receiving sleeve. The guiding sleeve is arranged above the receiving sleeve and is movably sleeved outside the guiding rod. The guiding sleeve is fixedly installed on the galvanizing table and synchronously drops with the galvanizing table to strike the corresponding receiving sleeve.

[0013] Further, a through hole for installing the guiding sleeve is opened on the galvanizing table. The guiding sleeve is installed in the through hole. The guiding sleeve has a third enlarged diameter section, which is located below the galvanizing table and abuts against the galvanizing table.

[0014] Further, the galvanizing rake has a number of rake teeth arranged side by side. The insulator fitting has a connecting groove for the rake teeth to enter. By inserting the rake teeth of the galvanizing rake into the connecting groove of the insulator fitting, the insulator fitting is installed on the galvanizing rake. When the galvanizing table is in the second state, the galvanizing rake with the insulator fitting is placed on the galvanizing table, and the rake teeth of the galvanizing rake are placed vertically upward or inclined upward.

[0015] The advantages of the present invention are as follows: The post - galvanizing treatment equipment for insulator fittings of the present invention makes the hanging zinc and zinc spurs on the insulator fittings automatically break away from the insulator fittings under the action of inertia by moving the zinc - vibrating workbench to the highest position and then freely dropping it to strike the receiving table, without affecting the galvanized layer tightly attached to the surface of the insulator fittings. Moreover, during operation, the galvanizing rake with the insulator fittings used in the galvanizing process can be directly transferred to the zinc - vibrating workbench as a whole, eliminating the need for the insulator fittings to be lifted and turned over, thus shortening the post - galvanizing treatment cycle.

[0016] The driving mechanism of the present invention utilizes the outer contour of the cam. The lifting - section profile is used to push the zinc - vibrating workbench upward. As the cam continues to rotate, when the zinc - vibrating workbench breaks away from the end of the lifting - section profile, the zinc - vibrating workbench instantly loses support and drops. As the cam continues to rotate, the zinc - vibrating workbench is continuously switched between the first state and the second state, thereby realizing multiple strikes of the zinc - vibrating workbench and improving the post - treatment effect.

[0017] The dropping - section profile of the present invention is composed of a straight - line - section profile and an arc - section profile. The center of the arc - section profile coincides with the rotation center of the cam, and the straight - line - section profile is in the radial direction of the arc - section profile. This design not only facilitates the machining of the cam but also ensures the structural strength at the end of the lifting - section profile of the cam.

[0018] When the zinc - vibrating workbench of the present invention moves to the highest position, the end of the lifting - section profile and the rotation center of the cam are on the same vertical line. At this time, the torque borne by the cam is zero, which can effectively guarantee the dynamic performance of the cam and extend the service life of the cam.

[0019] The cam of the present invention pushes the zinc - vibrating workbench upward through a roller. The roller rolls along the lifting - section profile of the cam as the cam rotates, converting sliding friction into rolling friction, reducing the frictional resistance, and reducing cam wear and energy loss.

[0020] The present invention facilitates the installation and positioning of the two mounting seats and the cam by providing a first diameter - enlarged section and a second diameter - enlarged section on the rotating shaft and cooperating with a limit sleeve.

[0021] The present invention reduces the space above the base occupied by the rotation of the cam by opening an avoidance groove on the base for the cam to rotate into, reducing the height dimension of the equipment and making the equipment structure more compact.

[0022] The zinc vibrating workbench of the present invention realizes the moving guiding function through the cooperation of the guiding rod and the guiding sleeve. By sleeving each receiving sleeve of the receiving table on the outside of the guiding rod, the space occupied by the receiving table can be effectively reduced, making the equipment more compact. Moreover, the zinc vibrating workbench uses the guiding sleeve to complete the knocking action, protecting the zinc vibrating workbench from damage and extending its service life.

[0023] The present invention sets a third diameter-expanded section on the guiding sleeve. When the zinc vibrating workbench moves downward and knocks against the receiving sleeve, the third diameter-expanded section is used to bear the acting force of the zinc vibrating workbench on the guiding sleeve, enhancing the connection strength between the guiding sleeve and the zinc vibrating workbench and preventing the guiding sleeve from disengaging from the through hole.

[0024] The galvanizing rake of the present invention can separate multiple insulator fittings with the rake teeth without interference, exposing the galvanized surfaces of the insulator fittings, which is beneficial for zinc hanging and zinc slag shedding. When the galvanizing rake with the insulator fittings is placed on the support table inside the zinc vibrating workbench, the rake teeth of the galvanizing rake are placed vertically upward or inclined upward to prevent the insulator fittings from disengaging from the rake teeth when the zinc vibrating workbench knocks against the receiving table.

[0029] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined purpose, the following details the specific embodiments, structures, features, and their effects of the present invention with reference to the drawings and preferred embodiments.

[0030] Embodiment This embodiment provides a post-treatment equipment for galvanizing insulator fittings, as Figures 1-3 shown, including a zinc vibrating workbench 1 and a receiving table. The zinc vibrating workbench 1 is used to place the galvanizing rake with the insulator fittings, and the receiving table is located below the zinc vibrating workbench 1. The zinc vibrating workbench 1 is driven by a driving mechanism to be in a first state and a second state; in the first state, the zinc vibrating workbench 1 is driven by the driving mechanism to move upward to the highest position; in the second state, the zinc vibrating workbench 1 freely falls from the highest position under the action of gravity and knocks against the receiving table below.

[0031] The driving mechanism includes a cam 2 and a rotary driver 4. The cam 2 is arranged below the zinc plating table 1 and is connected to the output end of the rotary driver 4 through a rotary shaft 3.

[0032] The cam 2 has a closed contour, as Figure 3 shown. The closed contour includes a falling section curve and a lifting section curve a for pushing the zinc plating table upward. The lifting section curve a has a head end and a tail end. The distance from the lifting section curve a to the center of rotation of the cam 2 gradually increases from the head end to the tail end. The two ends of the falling section curve are respectively connected to the tail end and the head end of the lifting section curve a. The cam forms an avoidance space on the side of the falling section curve away from the lifting section curve a for the zinc plating table 1 to freely fall downward. The falling section curve includes a straight line section curve c and an arc section curve b. The two ends of the straight line section curve c are respectively the first end and the second end. The first end of the straight line section curve c is connected to the tail end of the lifting section curve a. The two ends of the arc section curve b are respectively connected to the second end of the straight line section curve c and the head end of the lifting section curve a. The center of the arc section curve b coincides with the center of rotation of the cam. The straight line section curve c is located in the radial direction of the arc section curve b. The cam has a simple structure and is convenient to process. At the same time, the design of the straight line section curve c ensures the structural strength at the tail end of the lifting section curve of the cam. And when the zinc plating table moves to the highest position, the tail end of the lifting section curve a and the center of rotation of the cam 2 are on the same vertical line. At this time, the torque borne by the cam is zero, which can effectively ensure the dynamic performance of the cam 2 and extend the service life of the cam 2. To reduce the weight of the cam 2, a weight-reducing hole is also provided on the cam 2.

[0033] The rotary driver 4 uses a rotary motor. The rotary driver 4 is installed above a base 5. The central axis of the rotary shaft 3 is horizontally arranged. One side of the rotary shaft 3 is connected to the output end of the rotary driver 4 through a coupling 6, and the other side is installed on the base 5 through two mounting seats 7. The rotary driver 4 drives the rotary shaft 3 to rotate through the coupling 6, and the cam 2 rotates synchronously with the rotary shaft 3.

[0034] Two mounting seats 7 are mounted side by side on the base 5. A bushing 71 is installed in each mounting seat 7. The rotating shaft 3 is movably inserted into the bushings 71 of the two mounting seats 7. Between the two mounting seats 7 on the rotating shaft 3, there are a first enlarged diameter section 31 and a second enlarged diameter section 32. The first enlarged diameter section 31 is located on the side of the second enlarged diameter section 32 closer to the rotary drive 4. The outer diameter of the first enlarged diameter section 31 is larger than that of the second enlarged diameter section 32. The end face on the side of the first enlarged diameter section 31 away from the second enlarged diameter section 32 is in contact connection with the end face of the bushing 71 of the same-side mounting seat 7. The cam 2 is sleeved on the second enlarged diameter section 32. A limit sleeve 33 is sleeved on the second enlarged diameter section 32 on the side of the cam 2 away from the first enlarged diameter section 31. One end face of the cam 2 is in contact connection with the end face of the first enlarged diameter section 31 closer to the second enlarged diameter section 32, and the other side is in contact connection with the end face of the limit sleeve 33. The end face on the side of the second enlarged diameter section 32 away from the first enlarged diameter section 31 and the end face on the side of the limit sleeve 33 away from the cam 2 cooperate to form a limit surface, and the limit surface is in contact connection with the end face of the bushing 71 of the same-side mounting seat 7. By setting the first enlarged diameter section 31 and the second enlarged diameter section 32 on the rotating shaft 3 and cooperating with the limit sleeve 33, it is convenient for the installation and positioning of each mounting seat 7 and the cam 2. A relief groove 51 for the cam 2 to rotate into is formed between the two mounting seats 7 on the base 5, reducing the space above the base 5 occupied by the rotation of the cam 2, reducing the height dimension of the equipment, and making the equipment structure more compact.

[0035] The galvanizing table 1 has a roller 8 that can roll along the lift section profile a of the cam 2 towards the tail end. The roller 8 is rotatably mounted at the bottom of the galvanizing table 1 through a bearing 81. Two connecting seats 83 are mounted side by side on the bottom surface of the galvanizing table 1. The bearing 81 is installed between the two connecting seats 83 through a connecting shaft 82. The two ends of the connecting shaft 82 are respectively connected to the two connecting seats 83. The inner ring of the bearing 81 is sleeved on the connecting shaft 82, and the roller 8 is sleeved on the outer side of the outer ring of the bearing 81. As the cam 2 rotates, the roller 8 comes into contact with the lift section profile a of the cam 2 and rolls along the lift section profile a of the cam 2 towards the tail end. During this process, the cam 2 pushes the galvanizing table 1 to move upward through the roller 8. The roller 8 isolates the cam 2 from the galvanizing table 1, converting the sliding friction between the cam 2 and the galvanizing table 1 into the rolling friction between the cam 2 and the roller 8, reducing the frictional resistance, and reducing the wear of the cam 2 and the energy loss.

[0036] The receiving table includes four receiving sleeves 9, and the four receiving sleeves 9 are installed in a square shape on the base 5. The zinc vibration table 1 has four guiding mechanisms corresponding to the receiving sleeves 9 one by one. The guiding mechanism includes a guiding rod 91 and a guiding sleeve 92. The central axis of the guiding rod 91 is vertically arranged inside the receiving sleeve 9. The guiding sleeve 92 is arranged above the receiving sleeve 9 and is movably sleeved outside the guiding rod 91. The guiding sleeve 92 is fixedly installed on the zinc vibration table 1 and drops synchronously with the zinc vibration table 1 to strike the corresponding receiving sleeve 9. The zinc vibration table 1 realizes the function of moving guidance through the cooperation of the guiding rod 91 and the guiding sleeve 92. By sleeving each receiving sleeve 9 of the receiving table outside the guiding rod 91, the space occupied by the receiving table can be effectively reduced, making the equipment more compact. Moreover, the zinc vibration table 1 uses the guiding sleeve 92 to complete the knocking action, protecting the zinc vibration table 1 from damage and extending the service life of the zinc vibration table 1.

[0037] In this embodiment, spiral oil guiding and lubricating grooves 94 are formed on the outer wall of the guiding rod 91 of each guiding mechanism, which is beneficial to the full flow of lubricating oil throughout the guiding rod 91 and improves the lubrication effect between the guiding rod 91 and the guiding sleeve 92. A through hole for installing the guiding sleeve 92 is formed on the zinc vibration table 1. The guiding sleeve 92 is installed in the through hole. The guiding sleeve 92 has a third enlarged diameter section 93, which is located below the zinc vibration table 1 and abuts against the zinc vibration table 1. When the zinc vibration table 1 moves downward and strikes the receiving table 9, the third enlarged diameter section 93 bears the acting force of the zinc vibration table 1 on the guiding sleeve 92, improving the connection strength between the guiding sleeve 92 and the workbench and preventing the guiding sleeve 92 from disengaging from the through hole.

[0038] In this embodiment, the top surface of the zinc vibration table 1 has a zinc liquid recovery groove 11, which is convenient for the recycling of zinc liquid and zinc spines. A support table 12 for supporting the galvanizing rake is placed in the zinc liquid recovery groove 11 to lift the galvanizing rake and isolate it from the recycled zinc liquid, preventing the recycled zinc liquid from splashing back onto the insulator fittings.

[0039] In this embodiment, the galvanizing rake includes a rake body 10. The front end of the rake body 10 has a number of rake teeth 101 arranged in parallel. The rake teeth 101 are perpendicular to the rake body 10. The insulator fitting 103 has a connection groove 102 for the rake teeth 101 to enter. By inserting the rake teeth 101 of the galvanizing rake into the connection groove 102 of the insulator fitting 103, the insulator fitting 103 is installed on the galvanizing rake. The rake teeth of the galvanizing rake can separate multiple insulator fittings 103 from each other without interference, exposing the galvanized surface of the insulator fittings, which is beneficial to zinc hanging and zinc slag falling off. When the zinc vibration table 1 is in the second state, the galvanizing rake with the insulator fittings is placed on the support table 12 inside the zinc vibration table 1, and the rake teeth 101 of the galvanizing rake are placed vertically upward or inclined upward to prevent the insulator fittings from disengaging from the rake teeth when the zinc vibration table strikes the receiving table.

[0040] Working principle: The rotary drive 4 is started, and the rotary shaft 3 is driven to rotate through the coupling 6. The cam 2 rotates with the rotary shaft 3. The outer wall of the roller 8 contacts the lifting section profile a of the cam 2 and rolls along the lifting section profile a to the end. The cam 2 pushes the galvanizing workbench 1 to move upward to the highest position through the roller 8. The cam 2 continues to rotate, and the roller 8 leaves the lifting section profile a of the cam 2. The galvanizing workbench 1 falls onto the receiving table under the action of gravity and strikes the receiving table. The zinc hanging and zinc spines on the insulator fittings on the galvanizing rake in the galvanizing workbench 1 naturally separate from the insulator fittings under the action of inertia.

[0041] The post-treatment equipment for insulator fittings of the present invention enables the zinc hanging and zinc spines on the insulator fittings to automatically separate from the insulator fittings under the action of inertia by the method of moving the galvanizing workbench to the highest position and then freely dropping and striking the receiving table, without affecting the galvanized layer closely attached to the surface of the insulator fittings. Moreover, during operation, the galvanizing rake with insulator fittings used in the galvanizing process can be directly transferred to the galvanizing workbench as a whole, without the need for the insulator fittings to be raked and turned over, shortening the post-treatment cycle of galvanizing.

[0042] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
