Rib penetrating device and rib penetrating machine

Abstract

The utility model relates to a rib penetrating device and a rib penetrating machine, the rib penetrating device comprises a mounting frame, a rib penetrating assembly and a guide assembly, the rib penetrating assembly is arranged between the head end and the tail end of the mounting frame in the first horizontal direction and comprises two rib penetrating wheels arranged at intervals, and the guide assembly is arranged at the head end of the mounting frame and comprises two guide wheels; and the wheel diameter of the guide wheel is smaller than that of the rib penetrating wheel. Through the arrangement of the guide wheel, although the distance between every two adjacent rib penetrating holes of the rib penetrating plate is very close, due to the fact that the wheel diameter of the guide wheel is small and the length of the reinforcing steel bars is large, the parts, exposed out of the rib penetrating plate, of the penetrated reinforcing steel bars droop, and the parts, exposed out of the rib penetrating plate, of every two adjacent reinforcing steel bars have a large distance. Therefore, the guide wheel and the bar penetrating wheel cannot interfere with the part, exposed out of the bar penetrating plate, of the adjacent steel bar, so that the bar penetrating device can successfully penetrate the steel bar into the bar penetrating hole of the bar penetrating plate during bar penetrating, and bar penetrating failure caused by interference between the bar penetrating wheel or the guide wheel and the penetrated steel bar can be avoided.

Description

Technical Field

[0001] This application relates to the technical field of building pipe pile production, and particularly to a steel bar threading device and a steel bar threading machine. Background Art

[0002] Prestressed concrete pipe piles are widely used in the foundation construction of various buildings due to their high single-pile bearing capacity and convenient construction. The steel bar part is usually prefabricated into a cage shape, called cage steel bars. The cage steel bars mainly include several main steel bars evenly distributed circumferentially in a cage shape, spiral steel bars welded on the outer periphery of the main steel bars, a head plate steel bar threading plate assembly fixed at one end of several main steel bars, and a tail plate steel bar threading plate assembly fixed at the other end of several main steel bars. At present, the welding between several main steel bars and spiral steel bars is mainly carried out by a seam welder. Before seam welding, the threading operation of the main steel bars (i.e., PC steel bars) needs to be carried out.

[0003] The traditional method of threading the main steel bars is manual threading. The disadvantages of manual threading are high labor intensity, low threading efficiency and high cost. Therefore, in order to improve the threading efficiency, some scholars have developed an automatic steel bar threading machine to carry out automatic threading instead of manual threading. However, in some current pile types, the distance between two adjacent steel bars is relatively close, resulting in that when threading, the threading wheel is easily interfered with the part of the already threaded steel bar exposed outside the threading plate, and it is easy to be misaligned, resulting in ineffective threading and ultimately threading failure. Summary of the Utility Model

[0004] Based on this, the purpose of this application is to provide a steel bar threading device and a steel bar threading machine including this steel bar threading device, so as to solve the problem that the threading head of the existing steel bar threading machine is easily interfered with the part of the already threaded steel bar exposed outside the threading plate during threading, resulting in threading failure.

[0005] According to one aspect of this application, a steel bar threading device is provided, including:

[0006] A mounting frame, the mounting frame has a head end and a tail end oppositely arranged in a first horizontal direction;

[0007] A steel bar threading assembly, arranged between the head end and the tail end of the mounting frame, the steel bar threading assembly includes at least one group of threading wheel sets, and each group of threading wheel sets includes two threading wheels spaced apart in a second horizontal direction perpendicular to the first horizontal direction;

[0008] A guiding assembly, arranged at the head end of the mounting frame, the guiding assembly includes at least one group of guiding wheel sets, and each group of guiding wheel sets includes two guiding wheels spaced apart along the second horizontal direction, and the wheel diameter of the guiding wheel is smaller than the wheel diameter of the threading wheel.

[0009] In one embodiment, the mounting bracket is provided with a limiting component at the position where the tendon-passing component is provided, and the height position of the limiting component in the vertical direction can be adjusted; the limiting component has a limiting wheel, and the height of the limiting wheel in the vertical direction is higher than the height of the tendon-passing wheel, and the limiting wheel is located between the two tendon-passing wheels in the second horizontal direction.

[0010] In one embodiment, the tendon-passing device further includes a link assembly movably arranged on the mounting bracket. Two tendon-passing wheels in each group of tendon-passing wheel sets are connected to each other through the link assembly. One of the tendon-passing wheels can move along the second horizontal direction under the action of an external force to drive the link assembly to drive the other tendon-passing wheel to move synchronously in the opposite direction;

[0011] And / or, two guide wheels in each group of guide wheel sets are connected to each other through another link assembly. One of the guide wheels can move along the second horizontal direction under the action of an external force to drive the other link assembly to drive the other guide wheel to move synchronously in the opposite direction.

[0012] In one embodiment, the link assembly includes two first links and a second link that are rotatably connected end to end. One end of the first link away from the second link is rotatably connected to one of the tendon-passing wheels in each group of tendon-passing wheel sets or one of the guide wheels in each group of guide wheel sets, and the other end of the second link away from the first link is rotatably connected to the other tendon-passing wheel in each group of tendon-passing wheel sets or the other guide wheel in each group of guide wheel sets.

[0013] In one embodiment, a first slider is provided at the end where the first link is connected to the second link, a second slider is provided at the end of the first link away from the second link, and a third slider is provided at the end of the second link away from the first link. One of the tendon-passing wheels in each group of tendon-passing wheel sets or one of the guide wheels in each group of guide wheel sets is arranged on the second slider, and the other tendon-passing wheel in each group of tendon-passing wheel sets or the other guide wheel in each group of guide wheel sets is arranged on the third slider. The first slider is slidably connected to the mounting bracket through a first line rail extending in the vertical direction, and the second slider and the third slider are respectively slidably connected to the mounting bracket through a second line rail extending in the second horizontal direction.

[0014] In one embodiment, the position of the first line rail on the mounting bracket in the second horizontal direction can be adjusted so that the gap formed between the two tendon-passing wheels in each group of tendon-passing wheel sets and the gap formed between the two guide wheels in each group of guide wheel sets are located on the same straight line in the first horizontal direction.

[0015] In one embodiment, a clamping and dragging assembly is provided at the tail end of the mounting bracket in the first horizontal direction. The clamping and dragging assembly has at least one clamping and dragging wheel set, and each clamping and dragging wheel set includes two clamping and dragging wheels. The clamping and dragging wheels in all the clamping and dragging wheel sets are arranged in pairs at intervals in the vertical direction and / or in the second horizontal direction.

[0016] In one embodiment, the clamping and dragging assembly includes a first clamping plate and a second clamping plate that are spaced relatively apart in the second horizontal direction. The clamping and dragging wheels are respectively provided on the first clamping plate and the second clamping plate. The second clamping plate can move relative to the first clamping plate so that the gap size formed between the two paired clamping and dragging wheels can be changed.

[0017] In one embodiment, among all the clamping and dragging wheels, a first clamping and dragging wheel and a second clamping and dragging wheel are arranged at intervals in the vertical direction. The second clamping and dragging wheel is located below the first clamping and dragging wheel. The first clamping and dragging wheel is provided on the first clamping plate, and the second clamping and dragging wheel is provided on the second clamping plate. The second clamping plate can rotate relative to the first clamping plate about an axis extending in the first horizontal direction. In the direction from the second clamping plate to the first clamping plate, the wheel diameter of the second clamping and dragging wheel gradually decreases.

[0018] According to another aspect of the present application, a steel bar threading machine is provided, which includes a support frame, a driving device, and a steel bar threading device as described in any of the above solutions. The driving device is arranged on the support frame, and the steel bar threading device is arranged on the driving device. The driving device is used to drive the steel bar threading device to move relative to the support frame in the second horizontal direction and / or in the vertical direction.

[0019] For the above-mentioned steel bar threading device and steel bar threading machine, by arranging the steel bar threading assembly of the steel bar threading device between the head end and the tail end of the mounting bracket in the first horizontal direction, a distance is provided between the steel bar threading assembly and the head end of the steel bar threading device. And by arranging a guiding assembly at the head end of the mounting bracket in the first horizontal direction, the wheel diameter of the guiding wheel in the guiding assembly is smaller than the wheel diameter of the steel bar threading wheel in the steel bar threading assembly. Although the distance between two adjacent steel bar threading holes of the steel bar threading plate is very close, due to the smaller wheel diameter of the guiding wheel and the longer length of the steel bar, the part of the steel bar that has been threaded and exposed outside the steel bar threading plate will sag, resulting in a relatively large distance between the parts of two adjacent steel bars exposed outside the steel bar threading plate. Therefore, neither the guiding wheel nor the steel bar threading wheel will interfere with the parts of the adjacent steel bars exposed outside the steel bar threading plate. Thus, the steel bar threading device can successfully thread the steel bar into the steel bar threading holes of the steel bar threading plate during steel bar threading, and therefore, it can avoid the failure of steel bar threading caused by the interference between the steel bar threading wheel or the guiding wheel and the steel bar that has been threaded.

Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0028] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0029] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0030] In the present application, unless otherwise clearly defined and limited, if there are terms such as "mounted", "connected", "connected to", "fixed", etc., these terms should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] In the present application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0032] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0033] This application provides a steel bar threading device and a steel bar threading machine. The steel bar threading machine includes a steel bar threading device. The steel bar threading device is used to clamp a steel bar and convey the steel bar in a straight line direction to sequentially pass a plurality of steel bars through a plurality of steel bar threading holes formed in a circumferential direction on a steel bar threading plate, and then the spiral steel bar is spirally wound and welded on the passed steel bars by a seam welder, so as to finally form the steel bar part (i.e., the cage steel bar) of a prestressed concrete pipe pile.

[0034] Taking the steel bar threading machine for threading steel bars into a steel bar threading plate to finally form a cage steel bar as an example, the structures of the steel bar threading machine and the steel bar threading device in this application will be described below. It can be understood that in other embodiments, the steel bar threading machine and the steel bar threading device of this application are not limited to only threading steel bars into a steel bar threading plate to form a cage steel bar, and can also clamp and convey any rod-shaped workpiece to complete steel bar threading, which is not limited herein.

[0035] The steel bar threading machine provided by an embodiment of this application includes a support frame (not shown in the figure), a driving device (not shown in the figure), and Figure 1 and Figure 2 the steel bar threading device 10 shown as follows. The support frame is used for providing support. The driving device is arranged on the support frame. The steel bar threading device 10 is arranged on the driving device. The driving device can be a two-axis linear module or a robotic arm, etc., and is used to drive the steel bar threading device 10 to move relative to the support frame in a second horizontal direction (the Y direction shown in the figure) and / or in a vertical direction (the Z direction shown in the figure), so as to be able to clamp a steel bar from a stacking station of the steel bars and clamp the steel bar close to the steel bar threading plate.

[0036] Figure 1 and Figure 2The structural schematic diagram of the steel bar threading device 10 provided by an embodiment of the present application is shown. The steel bar threading device 10 provided by the present application includes a mounting frame 110, a steel bar threading assembly 120, and a guiding assembly 130. The mounting frame 110 has a head end 101 and a tail end 102 that are oppositely arranged in the first horizontal direction. The steel bar threading assembly 120 is installed between the head end 101 and the tail end 102, and the guiding assembly 130 is installed at the head end 101 of the mounting frame 110 (i.e., the end close to the steel bar threading plate during steel bar threading). The steel bar threading assembly 120 includes at least one set of steel bar threading wheel sets. Each set of steel bar threading wheel sets includes two steel bar threading wheels 121 spaced apart in the second horizontal direction. One of the steel bar threading wheels 121 is a driving steel bar threading wheel 1211 that is driven by a motor to rotate actively around its own central axis, and the other steel bar threading wheel 121 is a driven steel bar threading wheel 1212 that is driven by the steel bar to rotate around its own central axis. The guiding assembly 130 includes at least one set of guiding wheel sets. Each set of guiding wheel sets includes two guiding wheels 131 spaced apart in the second horizontal direction. The wheel diameter of the guiding wheel 131 is smaller than the wheel diameter of the steel bar threading wheel 121. In the embodiment shown in the figure, the steel bar threading assembly 120 has only one set of steel bar threading wheel sets, and the guiding assembly 130 has only one set of guiding wheel sets. The two steel bar threading wheels 121 of the steel bar threading wheel set and the two guiding wheels 131 of the guiding assembly 130 can jointly clamp the steel bar, and the two steel bar threading wheels 121 can convey the steel bar while clamping the steel bar, so that the steel bar can be inserted into the steel bar threading hole of the steel bar threading plate in the direction from the tail end 102 to the head end 101. The guiding wheel 131 of the guiding assembly 130 can play a guiding role at the head end 101 of the steel bar threading device 10, so that the steel bar can be aligned with the steel bar threading hole on the steel bar threading plate and the steel bar can be smoothly inserted into the steel bar threading hole. However, the number of the steel bar threading wheel sets and the guiding wheel sets is not limited to only one set respectively, and there can be multiple sets respectively, which is not limited herein.

[0037] Thus, by arranging the steel bar threading assembly 120 between the head end 101 and the tail end 102 of the mounting frame 110, the steel bar threading assembly 120 is at a certain distance from the head end 101 of the steel bar threading device 10. And by arranging the guiding assembly 130 at the head end 101 of the mounting frame 110 along the first horizontal direction, and the wheel diameter of the guiding wheel 131 in the guiding assembly 130 is smaller than the wheel diameter of the steel bar threading wheel 121 in the steel bar threading assembly 120. Although the distance between two adjacent steel bar threading holes of the steel bar threading plate is very close, due to the smaller wheel diameter of the guiding wheel 131 and the longer length of the steel bar, the part of the inserted steel bar exposed outside the steel bar threading plate will sag, resulting in a large distance between the parts of two adjacent steel bars exposed outside the steel bar threading plate. That is, the farther away from the steel bar threading plate, the greater the sagging distance of the steel bar. Therefore, neither the guiding wheel 131 nor the steel bar threading wheel 121 will interfere with the part of the adjacent steel bar exposed outside the steel bar threading plate, so that the steel bar threading device 10 can successfully insert the steel bar into the steel bar threading hole of the steel bar threading plate during steel bar threading, and thus can avoid the failure of steel bar threading caused by the interference between the steel bar threading wheel 121 or the guiding wheel 131 and the inserted steel bar.

[0038] Further, in order to be able to perform the actions of clamping and releasing the steel bars and to be able to adapt to steel bars of different diameters, the distance between the two steel bar passing wheels 121 of each group of steel bar passing wheel sets in the steel bar passing assembly 120 and the distance between the two guiding wheels 131 of each group of guiding wheel sets in the guiding assembly 130 are variable. In a specific implementation manner, referring to Figure 1 and Figure 3 , a first driving cylinder 122 and a connecting rod assembly 140 are provided on the mounting frame 110. One of the two steel bar passing wheels 121 in each group of steel bar passing wheel sets is drivingly connected to the first driving cylinder 122, and the two steel bar passing wheels 121 in each group of steel bar passing wheel sets are connected to each other through the connecting rod assembly 140. One of the steel bar passing wheels 121 can move along the second horizontal direction under the external force applied by the first driving cylinder 122 to drive the connecting rod assembly 140 to drive the other steel bar passing wheel 121 to move synchronously in the opposite direction, so as to realize that the two steel bar passing wheels 121 approach or move away from each other simultaneously.

[0039] Similarly, as shown in Figure 4 , the mounting frame 110 is further provided with a second driving cylinder 132 at the first end 101 along the first horizontal direction. One of the two guiding wheels 131 in each group of guiding wheel sets is drivingly connected to the second driving cylinder 132, and the two guiding wheels 131 in each group of guiding wheel sets are connected to each other through another connecting rod assembly 140. One of the guiding wheels 131 can move along the second horizontal direction under the external force applied by the second driving cylinder 132 to drive the connecting rod assembly 140 to drive the other guiding wheel to move synchronously in the opposite direction, so as to similarly realize that the two guiding wheels 131 approach or move away from each other simultaneously.

[0040] Of course, the method of enabling the two steel bar passing wheels 121 or the two guiding wheels 131 to approach or move away from each other simultaneously is not limited to the method of setting the connecting rod assembly 140. For example, it can also be achieved by respectively connecting two driving cylinders to a corresponding one of the two steel bar passing wheels 121 in each group of steel bar passing wheel sets, or respectively connecting to a corresponding one of the two guiding wheels 131 in each group of guiding wheel sets. Therefore, it is also possible that only the two steel bar passing wheels 121 in the steel bar passing wheel set are connected to each other through the connecting rod assembly 140, or only the two guiding wheels 131 in the guiding wheel set are connected to each other through the connecting rod assembly 140, which is not limited herein. However, connecting the two steel bar passing wheels 121 in the steel bar passing wheel set and the two guiding wheels 131 in the guiding wheel set to each other through the connecting rod assembly 140 can reduce the number of driving cylinders and save the production and manufacturing cost of the equipment.

[0041] Regarding the structure of the connecting rod assembly 140, please continue to refer to Figure 3 and Figure 4, the connecting rod assembly 140 includes two first connecting rods 141 and second connecting rods 142 that are rotatably connected end to end. One end of the first connecting rod 141 away from the second connecting rod 142 is rotatably connected to one of the steel-passing wheels 121 of each group of steel-passing wheel sets or one of the guiding wheels 131 of each group of guiding wheel sets. One end of the second connecting rod 142 away from the first connecting rod 141 is rotatably connected to the other steel-passing wheel 121 of each group of steel-passing wheel sets or the other guiding wheel 131 of each group of guiding wheel sets. When the two steel-passing wheels 121 or the two guiding wheels 131 approach each other, the connecting rod assembly 140 assumes an inverted V shape, enabling the two steel-passing wheels 121 or the two guiding wheels 131 to approach simultaneously to clamp the steel bar. When the two steel-passing wheels 121 or the two guiding wheels 131 move away from each other, the connecting rod assembly 140 can change from the inverted V shape to a straight line shape to release the steel bar.

[0042] Furthermore, on this basis, to prevent the failure of the steel bar picking before steel passing due to the inability of the two steel-passing wheels 121 and the two guiding wheels 131 to accurately clamp the steel bar, the lengths of the first connecting rod 141 and the second connecting rod 142 are equal, and as Figure 3 and Figure 4 shown, first sliders 111 are provided at the ends of the first connecting rod 141 and the second connecting rod 142. A second slider 112 is provided at one end of the first connecting rod 141 away from the second connecting rod 142, and a third slider 113 is provided at one end of the second connecting rod 142 away from the first connecting rod 141. One of the steel-passing wheels 121 of each group of steel-passing wheel sets or one of the guiding wheels 131 of each group of guiding wheel sets is arranged on the second slider 112, and the other steel-passing wheel 121 of each group of steel-passing wheel sets or the other guiding wheel 131 of each group of guiding wheel sets is arranged on the third slider 113. The first slider 111 is slidably connected to the mounting frame 110 through a first linear guide 114 extending in the vertical direction. The second slider 112 and the third slider 113 are respectively slidably connected to the mounting frame 110 through a second linear guide 115 extending in the second horizontal direction.

[0043] In this way, under the guidance of the first linear guide 114, the connecting end of the first connecting rod 141 and the second connecting rod 142 can only move in the vertical direction. Under the guidance of the second linear guide 115, the end of the first connecting rod 141 away from the second connecting rod 142 and the end of the second connecting rod 142 away from the first connecting rod 141 can only move in the second horizontal direction. And because the lengths of the first connecting rod 141 and the second connecting rod 142 are equal, the two steel-passing wheels 121 must be symmetric with respect to the central axis of a steel bar to be clamped. By the same token, the two guiding wheels 131 must also be symmetric with respect to the central axis of a steel bar to be clamped. Therefore, centering clamping can be achieved to avoid the failure of steel bar picking.

[0044] Since the steel bars extend in a straight line, if the steel bars are to be clamped at different positions along the axial direction of the steel bars for transferring the steel bars, the gaps formed by the two steel bar passing wheels 121 in each group of steel bar passing wheel sets and the gaps formed by the two guiding wheels 131 in each group of guiding wheel sets need to be on the same straight line. To achieve this purpose, referring to Figure 5 , the mounting frame 110 is respectively provided with first adjusting blocks 116 at its head end 101 along the first horizontal direction and at the position where the steel bar passing assembly 120 is installed. The first linear guide 114 is installed on the first adjusting blocks 116. The first adjusting blocks 116 are fixedly installed on the mounting frame 110 through adjusting screws, so that the positions of the first adjusting blocks 116 and the first linear guide 114 along the second horizontal direction on the mounting frame 110 can be adjusted. Thus, pre-adjustment can be carried out before the steel bar passing work, so that the gaps formed by the two steel bar passing wheels 121 in each group of steel bar passing wheel sets and the gaps formed by the two guiding wheels 131 in each group of guiding wheel sets are located on the same straight line in the first horizontal direction, and then the steel bars can be smoothly clamped at different positions along the axial direction of the steel bars.

[0045] It should be noted that since the steel bars are dozens of meters long, when the steel bar passing assembly 120 and the guiding assembly 130 clamp and move the steel bars, the end of the steel bar (i.e., the end of the steel bar far from the steel bar passing plate) will surely droop, which will cause the part of the steel bar close to the steel bar passing plate to tilt upward, and then it may not be able to smoothly align with the steel bar passing holes of the steel bar passing plate, resulting in the failure of passing the steel bars. To solve this problem and further ensure the success of passing the steel bars, the steel bar passing device 10 also has a limiting assembly 150 at the position where the steel bar passing assembly 120 is installed. The limiting assembly 150 has a limiting wheel 151. The height of the limiting wheel 151 in the vertical direction is higher than the height of the steel bar passing wheel 121, and the limiting wheel 151 is located between the two steel bar passing wheels 121 in the second horizontal direction, so that the limiting wheel 151 can limit the steel bar in the vertical direction and prevent the steel bar from tilting upward. Preferably, the height position of the limiting assembly 150 in the vertical direction can be adjusted to adapt to limiting steel bars with different diameters.

[0046] As described above, since the length of a single steel bar is long and the tail end 102 of a single steel bar will droop, and the steel bar passing plate will penetrate dozens of steel bars. To avoid the interference of the penetrated steel bars due to drooping, in a better embodiment, as Figure 1 and Figure 2 shown, the steel bar passing device 10 also has a clamping and dragging assembly 160 at its tail end 102 along the first horizontal direction, that is, the clamping and dragging assembly 160 is arranged at one end of the mounting frame 110 along the first horizontal direction away from the guiding assembly 130. The clamping and dragging assembly 160 has at least one clamping and dragging wheel set. Each clamping and dragging wheel set includes two clamping and dragging wheels 161. The clamping and dragging wheels 161 in all the clamping and dragging wheel sets are arranged in pairs at intervals along the vertical direction and / or along the second horizontal direction.

[0047] In this way, by setting the clamping and dragging component 160, the paired clamping and dragging wheels 161 in the clamping and dragging component 160 can clamp and drag the tail end 102 of the steel bar at the tail end 102 of the steel bar threading device 10, preventing the threaded steel bars from crossing each other, and can also reduce the resistance of the steel bar in the first horizontal direction by means of the rolling of the clamping and dragging wheels 161, so as to facilitate the steel bar threading.

[0048] It can be understood that in some other embodiments, only the steel bar threading component 120 and the guiding component 130 can be set, or only the steel bar threading component 120 and the clamping and dragging component 160 can be set. However, it is obvious that setting the steel bar threading component 120, the guiding component 130 and the clamping and dragging component 160 simultaneously is more conducive to successful steel bar threading.

[0049] In the specific structure of the clamping and dragging component 160, in some embodiments, as Figure 5 shown, the clamping and dragging component 160 includes a third driving cylinder 164 and two first clamping plates 162 and second clamping plates 163 that are relatively spaced apart along the second horizontal direction. Clamping and dragging wheels 161 are respectively provided on the first clamping plate 162 and the second clamping plate 163. The second clamping plate 163 can move relative to the first clamping plate 162 under the drive of the third driving cylinder 164, so that the gap size formed between the paired two clamping and dragging wheels 161 can be changed, so as to be able to clamp the steel bar together with the steel bar threading wheel 121 and the guiding wheel 131, and can release the steel bar after the steel bar threading is completed.

[0050] In Figure 5 the specific embodiment shown, all the clamping and dragging wheels 161 include a first clamping and dragging wheel 1611 and a second clamping and dragging wheel 1612 that are spaced apart along the vertical direction. The second clamping and dragging wheel 1612 is located below the first clamping and dragging wheel 1611. The first clamping and dragging wheel 1611 is provided on the first clamping plate 162, and the second clamping and dragging wheel 1612 is provided on the second clamping plate 163. The second clamping plate 163 can rotate relative to the first clamping plate 162 around an axis extending along the first horizontal direction under the drive of the third driving cylinder 164, and in the direction from the second clamping plate 163 to the first clamping plate 162, the wheel diameter of the second clamping and dragging wheel 1612 gradually decreases, that is, the outer peripheral surface of the second clamping and dragging wheel 1612 is inclined. In this way, when the second clamping plate 163 rotates relative to the first clamping plate 162 to release the steel bar, the steel bar can slide down along the inclined outer peripheral surface of the second clamping and dragging wheel 1612, so that the steel bar is more easily separated from the steel bar threading device 10.

[0051] In this embodiment, in addition to the first clamping and dragging wheels 1611 and the second clamping and dragging wheels 1612, all the clamping and dragging wheels 161 further include a third clamping and dragging wheel 1613 and a fourth clamping and dragging wheel 1614 that are arranged at intervals along the second horizontal direction. The third clamping and dragging wheel 1613 and the first clamping and dragging wheel 1611 are arranged on the first clamping plate 162 together, and the fourth clamping and dragging wheel 1614 and the second clamping and dragging wheel 1612 are arranged on the second clamping plate 163 together. By arranging the third clamping and dragging wheel 1613 and the fourth clamping and dragging wheel 1614 on the basis of the first clamping and dragging wheel 1611 and the second clamping and dragging wheel 1612, the resistance during steel bar threading can be further reduced when the steel bar is conveyed and moves in the first horizontal direction, so that the steel bar can be more smoothly inserted into the threading hole of the threading plate.

[0052] In addition, in order to make the clamping and dragging assembly 160 adapt to steel bars of different diameters, preferably, a second adjusting block 165 is further provided on the first clamping plate 162 or the second clamping plate 163. One of the first clamping and dragging wheel 1611 and the second clamping and dragging wheel 1612 and one of the third clamping and dragging wheel 1613 and the fourth clamping and dragging wheel 1614 are connected to the second adjusting block 165. The second adjusting block 165 is connected to the first clamping plate 162 or the second clamping plate 163 through an adjusting screw, so that the gap between the first clamping and dragging wheel 1611 and the second clamping and dragging wheel 1612 can be changed by adjusting the position of the second adjusting block 165, and the gap between the third clamping and dragging wheel 1613 and the fourth clamping and dragging wheel 1614 can be changed, so that the size of the above gap can be adjusted according to the diameter of the steel bar.

[0053] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
