Description

Technical Field

[0001] The present invention relates to the field of metal surface treatment, and particularly to a method for leveling an operating rod. Background Art

[0002] Channel steel is a common engineering steel. A guide groove is provided on the channel steel, and the cross-sectional shape of the guide groove is usually in the shape of "匚"; it plays an important role in industrial production. For example, in some sliding devices, the channel steel is used as a guide rail for sliding components. To enable the sliding components to slide smoothly, rollers adapted to the guide groove are installed on the sliding components. When the rollers roll in the "匚"-shaped guide groove, the sliding components can slide back and forth.

[0003] The structure of the cooperation between channel steel and rollers is relatively common in industrial applications. Taking the brush roll replacement mechanism as an example: After the steel plate is produced, it will be made into corresponding parts according to different usage requirements. However, before the steel plate is put into the production process, a preparation time for processing the steel plate needs to be reserved. During the preparation time, the steel plate will react with the moisture in the air, causing corrosion of the surface material of the steel plate. To remove the rust layer, the existing method is to use a grinding device that grinds the surface of the steel plate. This device polishes the surface of the steel plate by installing a brush roll, with less pollution; when this device grinds the steel plate, the brush roll contacts the surface of the steel plate. After long-term use, the grinding effect will also decline. Therefore, the old brush roll needs to be removed and placed on the brush roll replacement mechanism, and then a new roll is sent into the grinding device through the brush roll replacement mechanism for replacement.

[0004] The applicant designed a brush roll replacement mechanism, including a base and a roller seat arranged on the base. The roller seat is used to receive the brush roll; an operating rod driven by a hydraulic cylinder is arranged on the base. Multiple protrusions are arranged at intervals on the operating rod, and hooks that are hooked and matched with the protrusions are arranged on the roller seat. When the operating rod extends, the protrusions are matched with the hooks, and then the operating rod retracts, driving the roller seat to slide, and reciprocating alternately until the roller seat slides to the corresponding position to achieve the purpose of transporting the brush roll.

[0005] As Fig.18 shown, in the roll replacement mechanism, the operating rod is the sliding component. To make the sliding and telescoping process of the operating rod smoother, multiple spaced mounting sections are provided on the operating rod. Rollers are connected to both sides of each mounting section. A guide rail made of channel steel is arranged on the base. The guide rails are symmetrically arranged in the left-right direction, and the two "匚"-shaped guide grooves face each other. The rollers on both sides of the operating rod roll in the corresponding guide grooves, enabling the operating rod to smoothly extend and retract relative to the channel steel guide rail; however, such a design still has deficiencies.

[0006] As Fig.15aAs shown in the figure, after the action rod is extended, it usually exceeds the outer end of the channel steel guide rail; ideally, the outer circumference of multiple rollers should be in close contact with the bottom wall and the top wall of the guide groove at the same time, but due to the manufacturing and installation errors of the rollers, there is a tiny gap between the rollers and the top wall of the guide groove. After the action rod is extended, it is easy to deflect downward under the action of gravity, making it difficult for the protrusion on the action rod to be stably hung on the hook. At this time, the extended action rod is in a grinding and brushing production line with a harsh environment, and it is difficult to adjust it horizontally.

[0007] If the structure of channel steel and roller is replaced with a higher precision linear guide structure, the phenomenon of action rod deflection can indeed be improved. However, the cost of linear guide mechanism is high and the cleanliness of the use environment is also strict, which makes it difficult to adapt to the grinding and brushing production line with harsh environment. Summary of the invention

[0008] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a method for leveling an action rod, by selecting at least one leveling section on the installation section of the action rod, and arranging two leveling screws acting on the upper and lower ends of the rotating shaft on the leveling section, so that by rotating the leveling screws, the rotating shaft can be acted on and the roller of the leveling section can contact the top wall of the guide groove in the longitudinal direction, so that the action rod can remain horizontal without deflecting downward when it extends out of the outer end of the channel steel track. Without increasing the cost, the smoothness of the extension and retraction of the action rod is improved, the protrusion on the action rod is stably matched with the hook, and the roller changing efficiency is indirectly improved.

[0009] The technical solution of the present invention is achieved in this way: A method for leveling an action rod comprises the following steps: S1: Selecting a leveling section; selecting at least one installation section on the action rod as the leveling section, and opening a strip groove on the side of the leveling section to penetrate the installation section from left to right, and the strip groove extends in the longitudinal direction; S2; Installation; insert a rotating shaft into the strip groove so that the rotating shaft can float up and down in the strip groove; then install rollers at both ends of the rotating shaft, and make the rollers at both ends of the rotating shaft respectively in the corresponding guide grooves, and then set a leveling assembly on the leveling section, the leveling assembly includes two leveling screws directly or indirectly threaded on the leveling section, and the two leveling screws act on the upper and lower ends of the rotating shaft respectively; S3; Leveling; by rotating the two leveling screws, the shaft moves longitudinally in the strip groove and stops at the corresponding position until the gap between the roller and the top wall of the guide groove is eliminated, thereby ensuring that the action rod does not deflect downward when extending out of the outer end of the channel steel guide rail.

[0010] Preferably, step S1a is further included after step S1: pre-setting a leveling support member; the leveling support member is a connecting block, a strip groove is firstly processed on the connecting block to penetrate the connecting block horizontally, and leveling screw holes connected to the strip groove are processed at both upper and lower ends of the connecting block; S1b: welding; welding the two processed connecting blocks to the two sides of the leveling section respectively, so that the strip grooves on the connecting blocks correspond to the strip grooves on the leveling section; In step S2, on both sides of the leveling section, two leveling screws are screwed into the leveling screw holes at the upper and lower ends of the connecting block respectively, and the two leveling screws act on the upper and lower ends of the rotating shaft respectively.

[0011] Preferably, after step S1, step S1a is further included: processing; leveling screw holes are provided at both upper and lower ends of the leveling section, so that the rotating shaft passing through the strip groove is connected to the outside through the leveling screw holes; In step S2, two leveling screws are respectively screwed into the leveling screw holes at the upper and lower ends of the leveling section, and the two leveling screws act on the upper and lower ends of the rotating shaft respectively; the action rod itself can also provide a threaded connection carrier for the leveling screws, so that the leveling screws can stably act on the rotating shaft.

[0012] Preferably, in step S1a, the upper and lower leveling screw holes are located in the middle position of the leveling section, and in step S2, the two leveling screw threads are engaged in the corresponding leveling screw holes and act on the upper and lower ends of the middle of the rotating shaft respectively; the middle of the leveling section refers to the middle position in the width direction, which position corresponds to the middle position of the rotating shaft, and the opening of the leveling screw hole at this position can make the two leveling screws act on the middle of the rotating shaft to form a stable supporting force and adjustment force on the rotating shaft.

[0013] Preferably, in step S1a, the upper and lower leveling screw holes are symmetrically arranged on the action rod along the left-right direction, and in step S2, two groups of leveling screws are symmetrically arranged on the action rod, and the two leveling screws in each group act on the upper and lower ends of the rotating shaft respectively; thereby forming multiple adjustment support points on the shaft body of the rotating shaft to form a stable supporting force and adjustment force on the rotating shaft.

[0014] Preferably, in step S3, the leveling screw acting on the upper end of the rotating shaft is first rotated to separate it from the rotating shaft, and then the leveling screw acting on the lower end of the rotating shaft is rotated to press the rotating shaft upward until the roller is in close contact with the top wall of the guide groove, and then the leveling screw at the upper end is rotated again to act on the upper end of the rotating shaft again; the whole leveling process is simple and easy to operate, and the gap between the roller and the top wall of the guide groove at the leveling section can be quickly eliminated.

[0015] Preferably, in step S1, the installation section includes a leveling section with a strip groove and a non-leveling section without a strip groove, and the ratio of the number of leveling sections to the non-leveling sections is 1:1; in step S3, the roller at the leveling section position forms an upper contact point with the top wall of the guide groove, and the roller at the non-leveling section position forms a lower contact point with the bottom wall of the guide groove, and the number of upper contact points is the same as the number of lower contact points, so that the action rod is more stable when extending and retracting.

[0016] The beneficial effects of the present invention using the above technical solution are: Through the leveling method provided by the present invention, the roller located on the leveling section of the action rod can be brought into contact with the top wall of the guide groove, so that the channel steel track can limit the upward and downward swinging tendency of the action rod through the roller, so that after the action rod extends out of the outer end of the channel steel guide rail, it will not deflect downward due to the influence of gravity, so that the protrusion on the action rod and the hook can be stably matched, thereby improving the smoothness of the action rod and the efficiency of roller changing.

[0017] The leveling method of the present invention only requires opening a strip groove on the leveling section of the action rod and adding a leveling component to the action rod, without replacing the entire channel steel guide rail. Overall, the cost of the roller changing mechanism is not significantly increased, and the practicality and economy are strong. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0021] The present invention has multiple embodiments, and the specific implementation methods are as follows: Example 1: Figure 1-19 As shown, the present embodiment provides an action rod leveling method, which is applied in a progressive brush roller replacement mechanism, which is used for unloading and loading rollers in a grinding and brushing production line 4 of a steel plate, and comprises a base 1 and a roller seat 2 for supporting the brush roller, wherein a first track plate 11 is mounted on the base 1, and a second track plate 12 connected to the first track plate 11 is mounted in the grinding and brushing production line 4, and a rotating wheel is mounted on the side of the roller seat 2, and the rotating wheel rolls on the first track plate 11 and the second track plate 12, so that the roller seat 2 can move forward or retreat backward on the base 1 along its own length direction; a power assembly 3 is also provided on the base 1, and the power assembly 3 includes an action rod 31 and a telescopic driving member 39, and the telescopic driving member 39 is connected to the action rod 31, and can drive the action rod 31 to extend forward or retract backward by its own telescopic movement; a plurality of protrusions 32 arranged at intervals in front and back are provided on the action rod 31; a hanging structure 5 is provided on the roller seat 2, and the protrusion 32 has a front side surface 321 and a rear side surface 322 opposite to each other in front and back; The brush roller replacement mechanism has an advancing state and a retreating state. The advancing state refers to that the roller seat 2 advances toward the inside of the grinding brush production line 4 to receive the old brush roller or to feed in the new brush roller, and the retreating state refers to that the roller seat 2 drives out of the grinding brush production line 4. When the brush roller replacement mechanism is in the advancing state, the action rod 31 retracts and makes the front side surface 321 of the rearmost position protrusion 32 cooperate with the hanging structure 5. At this time, the telescopic driving member 39 can drive the action rod 31 to extend forward to drive the roller seat 2 to advance forward. Then, the telescopic driving member 39 drives the action rod 31 to retract and makes the front side surface 321 of the next protrusion 32 cooperate with the hanging structure 5, and this cycle is repeated until the roller seat 2 advances forward to the corresponding position. Figure 1-9 As shown, when the brush roller replacement mechanism is in the retracting state, the action rod 31 extends forward and makes the rear side surface 322 of the protrusion 32 at the front end position cooperate with the hanging structure 5. At this time, the telescopic driving member 39 drives the action rod 31 to retract backward to drive the roller seat 2 to retract backward. Then the telescopic driving member 39 drives the action rod 31 to extend forward and makes the rear side surface 322 of the next protrusion 32 cooperate with the hanging structure 5. This cycle is repeated until the roller seat 2 retracts backward to the corresponding position.

[0022] Furthermore, since the directions of the force received by the projection 32 and the hanging structure 5 are opposite when the roller seat 2 is in the advancing state and the retreating state, the hanging structure 5 has the function of switching the hanging direction. Specifically, Figure 16-17 As shown, the hanging structure 5 includes a base 51 connected to the roller seat 2, a swinging member 52 is rotatably connected to the base 51, a rear hook 54 and a front hook 53 are provided on the swinging member 52, a center hole is provided at the intersection of the front hook 53 and the rear hook 54, a rotating support shaft is provided on the base 51, and the rotating support shaft passes through the center hole, so that the swinging hook 52 can rotate forward and backward on the base 51; a rear limiter 55 and a front limiter 56 corresponding to the positions of the rear hook 54 and the front hook 53 respectively are provided on the base 51; The swing member 52 has a rear hooking mode corresponding to the advancing state and a front hooking mode corresponding to the retreating state. When the swing member 52 is in the rear hooking mode, the swing member 52 rotates and causes the front hook 53 to abut against the front limit member 56. At this time, the rear hook 54 is exposed outside the base 51 and forms a hooking fit with the front side surface 321 of the corresponding protrusion 32. At this time, after the action rod 31 extends forward, the front side surface 321 of the protrusion 32 will act on the rear hook 54 forward. Since the front limit member 56 abuts against the front hook 53, the rear hook 54 will not rotate, so that the roller seat 2 can move stably. When the swing member 52 switches to the front hooking mode, the swing member 52 rotates and The rear hook 54 is abutted against the rear limit member 55, at which time the front hook 53 is exposed outside the base 51 and forms a hooking fit with the rear side surface 322 of the corresponding protrusion 32; at this time, after the action rod 31 retracts backward, the rear side surface 322 of the protrusion 32 will act backward on the front hook 53, and since the rear limit member 55 abuts against the rear hook 54, the front hook 53 will not rotate, so that the roller seat 2 can retreat stably; by controlling the swing member 52 to swing, the protrusion 32 and the front hook 53 or the rear hook 54 form a hooking fit in different directions, so as to drive the roller seat 2 to slide in the corresponding direction. The design is sophisticated, so that the roller seat 2 can switch between the advancing state and the retreating state.

[0023] Furthermore, the protrusion 32 should be hooked with the front hook 53 or the rear hook 54, and the front hook 53 or the rear hook 54 should make room for the protrusion 32 to move when the protrusion 32 moves with the action rod 31. For example, when the front side surface 321 of the protrusion 32 cooperates with the rear hook 54, the protrusion 32 should cross over the rear hook 54 backwards; therefore, when the swing member 52 is in the rear hooking mode, the front hook 53 abuts against the front limit member 56, and at this time, a swinging space is formed between the rear hook 54 and the rear limit member 55 to allow the rear hook 54 to rotate. To allow the protrusion 32 to cross over the rear hook 54 when the action rod 31 is retracted; when the swing member 52 is in the front hooking mode, the rear hook 54 abuts against the rear limit member 55, and at this time, a swinging space allowing the front hook 53 to rotate is formed between the front hook 53 and the front limit member 56, so as to allow the protrusion 32 to cross over the front hook 53 when the action rod 31 is extended; the reserved rotation space can prevent the protrusion 32 from interfering when crossing the front hook 53 or the rear hook 54, so that multiple protrusions 32 can form corresponding hooking cooperation with the front hook 53 or the rear hook 54 in turn.

[0024] Furthermore, a conversion drive member for acting on the swing member 52 is provided on the base 51, and the conversion drive member can drive the swing member 52 to swing back and forth, so that the swing member 52 switches between the rear hooking mode and the front hooking mode; by controlling the conversion drive member, the swinging direction of the swing member 52 can be controlled, so that the switching efficiency of the swing member 52 is improved; specifically, the conversion drive member is a cylinder 57, and the base 51 has a pipe connection port 512 reserved at the position of the cylinder 57 for passing the air pipe, so as to facilitate the installation of the air pipe; the cylinder 57 has a telescopic rod 571 for making the swing member 52 swing back and forth; the telescopic process of the telescopic rod 571 of the cylinder 57 is fast and sensitive, and the switching efficiency is high.

[0025] Furthermore, to prevent the telescopic rod 571 from getting stuck when being extended or retracted, the cylinder body of the cylinder 57 is rotatably connected to the base 51 via a rotating shaft 513. When the telescopic rod 571 is extended or retracted, the cylinder 57 can rotate to adapt to the moving direction of the telescopic rod 571.

[0026] Furthermore, the swing angles of the front hook 53 and the rear hook 54 of the swing member 52 should be within a reasonable range. If the swing angle is too large, the telescopic length of the telescopic rod 571 needs to be lengthened, which requires a cylinder 57 with a larger stroke to achieve. If the swing angle is too small, the front hook 53 or the rear hook 54 is difficult to be completely retracted or exposed from the base 51. Therefore, in this embodiment, the swing angle range of the swing member 52 is 15°-25°. Within this angle range, the telescopic length of the telescopic rod 571 is relatively short, which can also ensure that the front hook 53 and the rear hook 54 can switch freely between the two states of being exposed from the base 51 or rotating to the base 51.

[0027] Furthermore, the telescopic rod 571 is elastically connected to the swing member 52, and the telescopic rod 571 is extended and retracted to form an elastic force on the swing member 52, so that the swing member 52 switches between the rear hooking mode and the front hooking mode; when the swing member 52 is in the rear hooking mode, and the protrusion 32 crosses the rear hook 54, the rear hook 54 can be elastically reset, so that the front side surface 321 of the protrusion 32 forms a hooking cooperation with the rear hook 54; when the swing member 52 switches to the front hooking mode, and the protrusion 32 crosses the front hook 53, the front hook 53 can be elastically reset, so that the rear side surface 322 of the protrusion 32 and ... The front hook 53 forms a hooking fit; after the telescopic rod 571 forms an elastic connection with the swinging member 52, it does not affect the driving and control effects of the swinging member 52, and can also make the front hook 53 or the rear hook 54 elastically reset after rotation, completing the hooking fit with the front side surface 321 or the rear side surface 322 of the protrusion 32; and when the front hook 53 or the rear hook 54 rotates and swings in the corresponding swinging space, the design of the elastic connection prevents the swinging member 52 from transmitting the reaction force of the swinging to the telescopic rod 571, effectively protecting the telescopic rod 571, achieving three goals at one stroke, and the design is ingenious.

[0028] Further, the telescopic rod 571 and the swinging member 52 are elastically connected as follows: a support 511 is provided on the base 51, a shaft sleeve 59 is rotatably connected to the swinging member 52, a through guide hole 593 is provided on the shaft sleeve 59, the telescopic rod 571 passes through the guide hole 593 and is slidably connected to the support 511; an elastic connection component is sleeved on the telescopic rod 571, and the elastic connection component includes a first compression spring 58 and a second compression spring 58a, a boss is provided on the side of the telescopic rod 571 close to the cylinder 57, the first compression spring 58 is arranged between the boss and the shaft sleeve 59 and provides a reset elastic force for the rear hook 54, and the second compression spring 58a is arranged between the support 511 and the shaft sleeve 59 And provide a restoring elastic force for the rear hook 54; specifically, the side of the boss facing the sleeve 59 has a first step surface 572, and along the penetration direction of the telescopic rod 571, countersunk holes 592 concentric with the guide hole 593 are opened at both ends of the sleeve 59, the diameter of the countersunk hole 592 is larger than the diameter of the guide hole 593, and a second step surface 591 is formed at the junction with the guide hole 593, the two ends of the first compression spring 58 are pressed between the first step surface 572 and the corresponding second step surface 591 to provide a restoring elastic force for the rear hook 54, and the two ends of the second compression spring 58a are pressed between the support 511 and the corresponding second step surface 591 to provide a restoring elastic force for the front hook 53.

[0029] Furthermore, in order to prevent the protrusion 32 from being easily disengaged after being engaged with the front hook 53 or the rear hook 54, thereby affecting the engaging effect of the action rod 31 on the roller seat 2, a snap-fitting protrusion 52a is provided on the rear hook 54 and the front hook 53, and a snap-fitting groove 32a is also provided on the front side 321 and the rear side 322 of the protrusion 32. When the rear hook 54 or the front hook 53 is engaged with the protrusion 32, the snap-fitting protrusion 52a is engaged with the corresponding snap-fitting groove 32a, thereby preventing the rear hook 54 or the front hook 53 from loosening when engaging with the protrusion 32.

[0030] Furthermore, the telescopic drive member 39 in the present embodiment is a hydraulic cylinder or an electric push rod, which has a piston rod 391. A connecting seat 313 is provided on the action rod 31. The piston rod 391 is connected to the action rod 31 through the connecting seat 313. In order to save the cost and space layout of the brush roller replacement mechanism, the telescopic drive member 39 in the present embodiment is a hydraulic cylinder or an electric push rod with a small stroke. That is to say, the distance that the piston rod 391 is extended or retracted each time is less than the total distance that the roller seat 2 gradually slides from the initial position to the corresponding position. Since the action rod 31 in the present embodiment is repeatedly hooked and matched with the front hook 53 or the rear hook 54 through multiple protrusions 32, the roller seat 2 gradually slides to the corresponding position in multiple times, which is equivalent to dividing the sliding stroke of the entire roller seat 2 into multiple small strokes. Therefore, the telescopic formation of the hydraulic cylinder or the electric push rod does not have to be the same as the total sliding stroke of the entire roller seat 2, thereby reducing the cost and occupied space of the telescopic drive member 39.

[0031] Furthermore, due to the harsh working environment inside the grinding and brushing production line 4, the linear guide mechanism with high precision and cost is not applicable to the action rod 31. Considering the cost and the roller changing stability of the brush roller changing mechanism, in this embodiment, channel steel guides 36 symmetrically arranged on both sides of the action rod 31 are provided on the base 1. A laterally extending guide groove 361 is formed inside the channel steel guide 36, and the cross-sectional shape of the guide groove 361 is in the shape of "匚". The action rod 31 has a plurality of installation segments 33 spaced front and back. The installation segment 33 refers to the length segment on the action rod 31 for installing the roller 34. A roller 34 matching the guide groove 361 is arranged on the installation segment 33. The plurality of rollers 34 roll in the guide groove 361 and form telescopic guidance for the action rod 31. By the rollers 34 rolling in the guide groove 361, the action rod 31 can be stably extended or retracted.

[0032] Furthermore, the channel steel guide 36 needs to provide stable support for the telescoping of the action rod 31. However, considering the use cost and the spatial layout of the brush roller changing mechanism, the channel steel guide 36 cannot be too long. Therefore, in this embodiment, the range of the ratio of the length of the channel steel guide 36 to the length of the action rod 31 is 1:1 - 10:7. That is to say, the channel steel guide 36 can be slightly longer than the length of the action rod 31, which can not only ensure the stable telescoping of the action rod 31, but also optimize the use cost and spatial layout of the brush roller changing mechanism.

[0033] Furthermore, as Fig.15a shown, in the ideal state, the outer diameter of the roller 34 matches the width of the guide groove 361. However, due to manufacturing errors and installation errors, it is difficult for the outer diameter of the roller 34 to exactly match the guide groove 361. If the outer diameter of the roller 34 is too large, it cannot roll freely in the guide groove 34, affecting the smoothness of the telescoping of the action rod 31. Therefore, when the action rod 31 is not extended, there will be a gap s between the roller 34 in the guide groove 361 and the top wall of the guide groove 361. Due to the existence of this gap s, when the action rod 31 extends, it will extend beyond the end of the channel steel guide 36. The extended part will deflect downward under its own gravity, making it difficult for the action rod 31 to maintain a horizontal state. If the deflection angle is too large, it will not only affect the smoothness of the retraction of the action rod 31, but may also cause the bump 32 on the action rod 31 to fail to engage with the front hook 53 or the rear hook 54, affecting the roller changing efficiency. Therefore, to avoid this phenomenon, as Fig.15b shown, this embodiment provides a method for leveling the action rod, including the following steps: S1: Select the leveling section 33a; select at least one installation section 33 on the action rod 31 as the leveling section 33a, and open a strip-shaped groove 311 that penetrates the installation section 33 left and right on the side of the leveling section 33a. The strip-shaped groove 311 extends longitudinally. S2; Installation; Insert a rotating shaft 35 into the strip groove 311, the outer diameter of the rotating shaft 35 is smaller than the extension length of the strip groove 311, thereby forming a space for the rotating shaft 35 to float up and down in the strip groove 311, so that the rotating shaft 35 can float up and down in the strip groove 311; then install the rollers 34 at both ends of the rotating shaft 35, and make the rollers 34 at both ends of the rotating shaft 35 respectively in the corresponding guide grooves 361, and then set a leveling assembly on the leveling section 33a, the leveling assembly includes two leveling screws 38 directly or indirectly threadedly engaged with the leveling section 33a, and the two leveling screws 38 act on the upper and lower ends of the rotating shaft 35 respectively; S3; Leveling; By rotating the two leveling screws 38, the rotating shaft 35 moves longitudinally in the strip groove 311 and stops at the corresponding position until the gap between the roller 34 and the top wall of the guide groove 361 is eliminated, thereby ensuring that the action rod 31 does not deflect downward when extending out of the outer end of the channel steel guide rail 36, thereby eliminating the tendency of the action rod 31 to deflect downward after being extended, so that the action rod 36 maintains a stable horizontal state when extending out of the outer end of the channel steel guide rail.

[0034] Further, if Figure 10-13 As shown, the leveling screw 38 needs a carrier to be threadedly connected, so after step S1, step S1a is further included: pre-setting a leveling support member; the leveling support member is a connecting block 37, firstly a strip groove 311 is processed on the connecting block 37 to penetrate the connecting block 37 horizontally, and leveling screw holes 371 connected to the strip groove 311 are processed at both upper and lower ends of the connecting block 37; S1b: welding; the two processed connecting blocks 37 are respectively welded to the two sides of the leveling section 33a, so that the strip groove 311 on the connecting block 37 corresponds to the position of the strip groove 311 on the leveling section 33a; In step S2, when the leveling screws 38 are installed on both sides of the leveling section 33a, the two leveling screws 38 are respectively screwed into the leveling screw holes 371 at the upper and lower ends of the connecting block 37, and the two leveling screws 38 act on the upper and lower ends of the rotating shaft 35 respectively. The connecting block 37 can provide a threaded connection carrier for the leveling screws 38, and the leveling screws 38 can stably act on the rotating shaft 35.

[0035] Furthermore, in step S3, the specific steps for leveling the entire action rod 31 are as follows: first, rotate the leveling screw 38 acting on the upper end of the rotating shaft 35 and separate it from the rotating shaft 35, then rotate the leveling screw 38 acting on the lower end of the rotating shaft 35 and press the rotating shaft 35 upward until the roller 34 is in close contact with the top wall of the guide groove 361, and then rotate the leveling screw 38 at the upper end again to make it act on the upper end of the rotating shaft 35 again; the entire leveling process is simple and easy to operate, and the gap between the roller 34 at the leveling section 33a and the top wall of the guide groove 36 can be quickly eliminated.

[0036] Furthermore, in this embodiment, not all the rotating shafts 35 of the rollers 34 can float up and down. Specifically, in step S1, the mounting section 33 includes a leveling section 33a with a strip groove 311 and a non-leveling section without a strip groove 311. The non-leveling section also uses a rotating shaft 35 to provide rotation support for the roller 34. The difference is that a circular hole 312 is opened on the non-leveling section, which runs through the non-leveling section in the horizontal direction and is used to pass the rotating shaft 35. The diameter of the circular hole 312 is the same as that of the rotating shaft 35. The outer diameters match, so the roller 34 installed on the non-leveling section cannot float up and down. In step S3, an upper contact point is formed between the leveling section 33a and the top wall of the guide groove 361, and a lower contact point is formed between the roller 34 at the non-leveling section position and the bottom wall of the guide groove 361. In order to ensure the telescopic stability of the action rod 31, the ratio of the number of leveling sections 33a to the number of non-leveling sections is 1:1, so that the number of upper contact points is the same as the number of lower contact points, making the action rod 31 more stable when telescoping.

[0037] Furthermore, in order to prevent the action rod 31 from shifting laterally when it is extended or retracted, and to make the retracting process smoother, an anti-lateral displacement structure is provided on the channel steel guide rail 36 and some rollers 34. For example, a guide wheel 315 that can rotate along a vertical axis is provided in each guide groove 361, and the outer peripheral surfaces of the two guide wheels 315 are respectively against the left and right sides of the action rod 31 to form a further telescopic guide for the action rod 31; for example, two rollers 34 rotatably connected to the two ends of the rotating shaft 35 form a roller group on the corresponding mounting section 33; wherein in at least one roller group on the action rod 31, the inner sides of the two rollers 34 are provided with wheel edges 314 protruding from the outer peripheral edges of the rollers 34, and the wheel edges 314 are attached to the inner side of the corresponding channel steel guide rail 36 to prevent the action rod 31 from shifting laterally when it is extended or retracted.

[0038] Embodiment 2: This embodiment is different from the above embodiment in that the two leveling screws 28 in this embodiment are not arranged on the connecting block 37, but are directly arranged on the action rod 31. Specifically, step S1a is further included after step S1: processing; leveling screw holes 371 are opened at both the upper and lower ends of the leveling section 33a, so that the rotating shaft 35 passing through the strip groove 311 is connected with the outside through the leveling screw holes 371; In step S2, the two leveling screws 38 are respectively screwed into the leveling screw holes 371 at the upper and lower ends of the leveling section 33a, and the two leveling screws 38 act on the upper and lower ends of the rotating shaft 35 respectively; the action rod 31 itself can also provide a threaded connection carrier for the leveling screws 38, so that the leveling screws 38 can stably act on the rotating shaft 35. Selecting the leveling screws 38 to act on the rotating shaft 35 can also achieve the same leveling effect as in the above embodiment.

[0039] Furthermore, in the present embodiment, there are two schemes for opening the leveling screw hole 371. The first opening scheme is to open the leveling screw hole 371 in the middle position of the leveling section 33a (not shown). Specifically, in step S1a, the upper and lower leveling screw holes 371 are located in the middle position of the leveling section 33a. In step S2, the two leveling screws 38 are threadedly engaged in the corresponding leveling screw holes 371, and act on the upper and lower ends of the middle of the rotating shaft 35 respectively. The middle of the leveling section 33a refers to the middle position in the width direction, which corresponds to the middle position of the rotating shaft 35. Opening the leveling screw hole 38 at this position can make the two leveling screws 38 act on the middle of the rotating shaft 35, so as to form a stable supporting force and adjustment force on the rotating shaft 35.

[0040] like Fig.14 As shown, the second opening scheme is to open symmetrically on the leveling section 33a. Specifically, in step S1a, the upper and lower leveling screw holes 371 are symmetrically arranged on the action rod 31 along the left-right direction. In step S2, two groups of leveling screws 38 are symmetrically arranged on the action rod 31, and the two leveling screws 38 in each group act on the upper and lower ends of the rotating shaft 35 respectively; thereby, multiple adjustment support points are formed on the shaft body of the rotating shaft 35. When adjusting the longitudinal position of the rotating shaft 35, the leveling screws 38 at the upper or lower end of the adjusting section 33a are rotated at the same time, thereby forming a stable supporting force and adjustment force on the rotating shaft 35.

[0041] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
