[0002] At present, the oil (gas) pipe fittings used in hydraulic and pneumatic systems are generally made of precision cold-drawn steel pipes that meet the national standard GB / T3639 as blank tubes. Modern equipment manufacturing industry has widely used high-precision ultra-high-precision hydraulic (gas) seamless steel pipes in liquid (gas) pipelines. Such products are generally manufactured by professional factories. The outer diameter of such products is usually 6-60mm, and the factory length is 6-8m, which belongs to ultra-slender tubes. A considerable proportion of the surface of such pipe fittings needs to be electro-galvanized on the outer diameter surface (and some need inner diameter surface). Since there are many diameter series specifications of such pipe fittings, the requirements for surface galvanizing are also very many according to the needs of users, such as white galvanizing, color galvanizing, black zinc, military green, etc. Different chemical conversion film varieties have different requirements for the degree of coating. There are many specifications and varieties in such a combination. The current status of the industry is still in a semi-manual and semi-automatic production line operation state where technology-intensive and labor-intensive coexist. It is difficult to meet the processing of products of different specifications on the same production line; and there is a lack of health protection for operators. Summary of the invention

[0121] According to the present invention, a precise and slender steel pipe fully automatic electrogalvanizing production line transfer and positioning working device 2000 is provided. Figure 1 to Figure 5 As shown, including:

[0122] A trough body 2001 extending in the transverse direction and arranged at intervals in the longitudinal direction, a first rail 200A is arranged in the longitudinal direction of the trough body 2001, and the first rail 200A is arranged at intervals from the trough body 2001 along the height direction; that is, the first rail 200A is suspended at the upper end of the trough body 2001;

[0123] The walking device 1000 is mounted on the upper end of the tank 2001.

[0124] The walking device 1000 comprises:

[0125] Support frame 300;

[0126] The walking frame 200 includes a walking frame, a driving motor 204 and walking wheels 203, wherein the walking frame is configured to be connected to the supporting frame 300, and the walking frame includes:

[0127] At least two longitudinal links 201 extend in the longitudinal direction and are arranged opposite to each other in the transverse direction; for example, in the present invention, two longitudinal links 201 are arranged in parallel in the transverse direction.

[0128] At least two transverse links 202, the transverse links 202 extending in the transverse direction and arranged relative to and connecting the longitudinal links 201 in the longitudinal direction; for example, in the present invention, two transverse links 202 are arranged in parallel in the longitudinal direction, and the transverse links 202 are fixedly connected to the longitudinal links 201, for example, they can be connected by welding or fasteners, so that the longitudinal links 201 and the transverse links 202 together form a walking frame.

[0129] The walking wheel 203 is pivotally connected to the walking frame and matched with the first track 200A, and the driving motor 204 is suitable for connecting with the walking wheel 203 to drive the walking wheel 203 to roll along the first track 200A; multiple walking wheels 203 are rotatably arranged on each of the longitudinal connecting rods 201 and matched with the first track 200A extending in the longitudinal direction; that is, the extension direction of the first track 200A is the same as that of the longitudinal connecting rod 201, and when the walking wheel 203 matches with the first track 200A, the frame can move along the first track 200A;

[0130] A driving motor 204, wherein the driving motor 204 is connected to at least one of the running wheels 203, so as to drive the running wheel 203 to roll along the first track 200A; that is, the driving motor 204 can be connected to one of the running wheels 203 via a reducer, so as to drive the frame to move along the first track 200A, thereby completing the transportation of the pipeline in the longitudinal direction.

[0131] Specifically, when the traveling frame 200 is working, the driving motor 204 drives the traveling wheel 203 to rotate, so that the traveling frame moves along the first track 200A. In actual application, the traveling frame 200 is erected on the upper end of the trough body, and the trough body is arranged along the longitudinal direction, and the pipeline is connected to the traveling frame 200 through a sling. By driving the traveling frame 200 to move along the longitudinal direction, the pipeline to be cleaned can be transferred to the corresponding trough body; the traveling frame 200 can realize the transfer of the sling in the longitudinal direction, greatly improving the transfer efficiency, and has a simple structure, safety and reliability, and low manufacturing cost.

[0132] That is to say, the support frame 300 is suspended on the first track 200A, and the first track 200A supports the entire walking device 1000 .

[0133] A lifting mechanism, comprising a lifting motor 400 and a guide wheel assembly 100, wherein the guide wheel assembly 100 is connected to the support frame 300 in a liftable manner, and the lifting motor 400 is installed on the support frame 300 and connected to the guide wheel assembly 100 to drive the guide wheel assembly 100 to move up and down;

[0134] A controller 1300, the controller 1300 is electrically connected to the driving motor 204 and the lifting motor 400, and is used to control the movement of the walking device 1000 in the longitudinal direction and the lifting and lowering of the guide wheel assembly 100 in the height direction;

[0135] Wherein, the first track 200A is perpendicular to the movement direction of the guide wheel assembly 100;

[0136] The guide wheel assembly 100 includes a plurality of guide wheel assemblies 100, which are symmetrically arranged on the support frame 300 on both sides of the trough body 2001 in the transverse direction, and a sling is connected between the mutually symmetrical guide wheel assemblies 100, and the two guide wheel assemblies 100 are lifted synchronously to ensure the horizontality of the sling, and a steel pipe is hung on the sling;

[0137] The transverse direction, the longitudinal direction and the height direction are perpendicular to each other.

[0138] It can be understood that when the transfer and positioning working device 2000 of the precision slender steel pipe fully automatic electrogalvanizing production line is working, the controller 1300 controls the drive motor 204 to drive the walking wheel 203 to rotate, so that the frame moves along the first track 200A. In actual applications, the walking frame 200 is erected on the upper end of the trough body, and the trough body is arranged along the longitudinal direction, and the steel pipe to be processed is connected to the walking frame 200 through a hanger. By driving the walking frame 200 to move along the longitudinal direction, the steel pipe to be processed can be transferred to the corresponding upper end of the trough body; the controller controls the lifting motor 400 to drive the roller chain 302 to rotate, thereby driving the roller assembly 100 to move downward, so as to transfer the steel pipe to be processed to the trough body. After cleaning is completed, the controller controls the lifting motor 400 to drive the roller chain 302 to rotate (in the opposite direction), thereby driving the roller assembly 100 to move upward, thereby transferring the steel pipe out of the tank body 2001; repeating the above operation arrangement, the controller controls the driving motor 204 and the lifting motor 400 to move in the longitudinal direction and the height direction in coordination, so as to complete the processing of the steel pipes to be processed in multiple tank bodies according to the specified process flow one by one; the transfer and positioning working device of the precision slender steel pipe fully automatic electrogalvanizing production line can realize the fully automatic processing of galvanized steel pipes of different specifications and varieties on the same production line, which is green and environmentally friendly, strengthens the safety protection of operators, and has a simple structure, safety and reliability, and low manufacturing cost.

[0139] In one example of the present invention, it also includes:

[0140] An exhaust system, the exhaust system comprising:

[0141] An air duct, comprising an input end and an output end, wherein the input end is arranged along the extension direction of the cleaning tank and connected to one side of the cleaning tank;

[0142] An induced draft fan is connected to the induced draft duct, and the induced draft fan is configured to generate wind that flows from an input end to an output end.

[0143] That is to say, since the production line is located in a closed production workshop 1200, and the processing solutions in the cleaning tank 1100 are mostly volatile solutions, the air in the production workshop 1200 is not circulated over time, which will cause harm to the workers. The gas in the production workshop 1200 is discharged and exchanged through the exhaust system 1600. Specifically, input ends are provided on both sides of the cleaning tank 1100 and the upper end of the production workshop 1200, and air inlets are provided at the input ends. For example, the air inlets can be arranged at intervals along the lateral direction of the cleaning tank 1100. It is worth noting that the exhaust system also includes a filter element, which is arranged close to the output end to purify the exhaust gas.

[0144] In one example of the present invention, Fig. 9 and Fig.10 As shown, it also includes:

[0145] A limiting wheel 205, wherein the limiting wheel 205 is pivotally disposed on at least one side of the longitudinal link 201, so that a contour surface of the limiting wheel 205 at least abuts against one side surface of the first track 200A;

[0146] In short, by providing the limiting wheels 205, the position of the frame in the lateral direction can be limited, so that the walking frame 200 is more stable and reliable during operation.

[0147] In one example of the present invention, Fig. 9 and Fig.10 As shown, the limiting wheels 205 are arranged on both lateral sides of the longitudinal link 201 and define a clamping space 205A, and the span of the clamping space 205A is equal to the span of the first track 200A;

[0148] That is, by arranging the limiting wheels 205 on both lateral sides of the longitudinal link 201, the position of each longitudinal link 201 corresponding to the first guide rail can be limited, so that the corresponding longitudinal link 201 is clamped by the clamping space 205A. Since the span of the clamping space 205A is equal to the span of the first track 200A, the overall structure connection can be made more compact and the movement accuracy can be higher.

[0149] Since the limiting wheels 205 directly abut against the two side surfaces of the first track 200A, the friction between the traveling frame 200 and the first track 200A can be reduced when the traveling frame 200 is running.

[0150] Of course, the present invention is not limited to this. A limiting wheel 205 may be provided on one of the two lateral sides of each longitudinal link 201. For example, a limiting wheel 205 may be provided on the inner side of the longitudinal link 201 at the same time. In this case, the lateral displacement is limited by abutment on the inner side of each first track 200A. A limiting wheel 205 may also be provided on the outer side of the longitudinal link 201. In this case, the lateral displacement is limited by abutment on the outer side of each first track 200A. Of course, a limiting wheel 205 may also be provided on the inner or outer side of one of the longitudinal links 201, and a limiting wheel 205 may be provided on the outer or inner side of the other longitudinal link 201.

[0151] Preferably, a plurality of limiting wheels 205 are provided on each longitudinal link 201 and are spaced apart along the longitudinal direction. For example, in the present invention, limiting wheels 205 are provided on both the inner side and the outer side of each longitudinal link 201 .

[0152] In one example of the present invention, Figure 8 and Fig.10As shown, the limiting wheel 205 includes a pivot hole penetrating the central axis position and mounting holes coaxially arranged with the pivot hole and arranged on both sides of the pivot hole;

[0153] Wherein, the pivot hole cooperates with the pivot shaft 208, and the mounting hole cooperates with the bearing 206;

[0154] Specifically, the pivot hole and the mounting hole form a stepped hole structure on the limiting wheel 205, that is, the inner diameter of the pivot hole is smaller than the inner diameter of the mounting holes on both sides thereof. When installing the limiting wheel 205, the bearing 206 is first installed in the mounting hole, and then sleeved on the pivot shaft 208, so that the pivot shaft 208 passes through the bearing 206 and the pivot hole in sequence, and finally the pivot shaft 208 is fixedly connected to the longitudinal link 201;

[0155] By providing two bearings 206 , the force on the limiting wheel 205 can be more uniform and reliable, and the friction between the pivot hole of the limiting wheel 205 and the limiting shaft can be reduced.

[0156] In one example of the present invention, Fig. 9 and Fig.11 As shown, it also includes:

[0157] A spacer sleeve 207, wherein the spacer sleeve 207 is sleeved on the pivot shaft 208, and one end of the spacer sleeve 207 abuts against the lower end surface of the longitudinal link 201, and the other end of the spacer sleeve 207 abuts against the bearing 206 in the mounting hole close to the longitudinal link 201;

[0158] The position of the limiting wheel 205 can be limited by providing the spacer 207 to prevent the limiting wheel 205 from moving up and down during the movement, thereby affecting the stability of the movement of the limiting wheel 205 .
