Description

Technical Field

[0001] The invention relates to the technical field of metal surface treatment devices, and in particular to an online surface treatment device for prestressed materials of high-speed railway sleepers. Background Art

[0002] Railway sleepers, their main function is to support the rails and evenly distribute the load of the train on the roadbed. The requirements for sleepers on high-speed railways are more stringent than those on ordinary railways. Because high-speed trains run at faster speeds, higher requirements are placed on the stability, accuracy and smoothness of the track system. At present, concrete sleepers are widely used in high-speed railways because they have the characteristics of high strength, high durability and good elastic modulus, and can withstand the huge dynamic load brought by high-speed travel.

[0003] In the process of producing concrete sleepers, in order to improve the tensile strength of concrete sleepers and provide pre-compression stress for concrete sleepers, a certain amount of rebar needs to be added during the production process of concrete sleepers. After the rebar is prepared, the rebar placed in the air is easily oxidized by the oxygen in the air, resulting in rust on the surface of the rebar. The rusted rebar will affect its mechanical properties and its adhesion to concrete. Therefore, the rebar needs to be derusted before use.

[0004] At present, laser rust removers are widely used because of their ability to quickly and accurately remove rust from metal surfaces. In the process of using laser rust removers to remove rust on rebar, due to the presence of threads on the rebar and the fact that the rebar is usually stacked, blind spots are easily generated when using the laser rust remover to clean the rust on the rebar, resulting in some positions of the rebar being unable to be effectively cleaned, affecting the overall rust removal efficiency of the rebar, thereby affecting the normal use of the rebar.

DETAILED DESCRIPTION

[0056] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] Embodiment 1: An online surface treatment device for prestressed materials of high-speed railway sleepers, such as Figure 1-Figure 5As shown, it includes a mounting frame 1, on which a laser rust remover is arranged; a first fixed plate 2, fixedly connected to the mounting frame 1, on which a plurality of first abutment columns 3 in a linear array are rotatably connected, two adjacent first abutment columns 3 are transmitted through gears, and a driving module for driving one of the first abutment columns 3 to rotate is arranged on the first fixed plate 2; a driving motor 4, fixedly connected to the mounting frame 1, an output shaft of the driving motor 4 is fixedly connected to a threaded rod, and the threaded rod on the output shaft of the driving motor 4 is threadedly connected to a first movable plate 5; a connecting column 6, fixedly connected to the first movable plate 5; a moving shell 7, slidably connected to the mounting frame 1, the moving shell 7 is fixedly connected to the connecting column 6, and the moving shell 7 is provided with the same number of second abutment columns 9 as the first abutment columns 3, and a plurality of first abutment columns 3 correspond one-to-one with a plurality of second abutment columns 9; a moving component, arranged on the mounting frame 1, and the moving component is used to change the position of the laser rust remover.

[0058] In the above scheme, the laser rust remover is an existing device, and its specific working process will not be described in detail; the first fixed plate 2 is located at the front of the upper side of the mounting frame 1, and is used to assist the first abutment column 3 thereon to position one end of the threaded steel to be processed; the driving module on the first fixed plate 2 is an existing device, which is not shown in the figure. In actual use, a servo motor can be selected. The driving module drives one of the first abutment columns 3 to rotate, and then the first abutment column 3 drives the remaining first abutment columns 3 to rotate through gears; and the specific number of the second abutment column 9 and the first abutment column 3 can be specifically selected by the staff. The figure and the text are only examples. The second abutment column 9 is used to fix the other end of the threaded steel; the driving motor 4 is located at the lower part of the rear side of the mounting frame 1; in this embodiment, the mounting frame 1 is used to place the threaded steel to be processed; and the second abutment column 9 is fixedly connected to the movable shell 7.

[0059] The working process of the above scheme is as follows: the staff uses the existing conveying device to arrange a batch of threaded steel bars that need to be derusted (the number must be controlled to be the same as the number of first abutment columns 3, and the length of the threaded steel bars to be processed should be slightly smaller than the initial minimum distance between the first abutment columns 3 and the second abutment columns 9) on the mounting frame 1 in sequence, and make the threaded steel bars correspond to all the first abutment columns 3 one by one, and then start the driving motor 4, and the output shaft of the driving motor 4 drives the first movable plate 5 to move forward through the threaded rod thereon, and the first movable plate 5 drives the connecting column 6 and the movable shell 7 to move synchronously, and then the movable shell 7 drives several second abutment columns 9 thereon to move forward synchronously, and pushes all the threaded steel bars forward until the front ends of all the threaded steel bars are respectively in contact with the rear sides of the adjacent first abutment columns 3, and then the first abutment column 3 and the adjacent second abutment column 9 cooperate with each other to clamp and fix the threaded steel bars between the two.

[0060] After all the threaded steel bars are fixed, the staff starts the laser rust remover on the mounting frame 1, so that the rust on the surface of the threaded steel bars is irradiated by the laser beam and expands due to heat and separates from the threaded steel bars, and controls the moving component to drive the laser rust remover to move back and forth to change the rust removal position.

[0061] In the above-mentioned process of cleaning the threaded steel bars, the staff starts the driving module, and the driving module drives one of the first abutment columns 3 to rotate, and the first abutment column 3 drives the adjacent first abutment columns 3 to rotate through the transmission of the gear thereon, thereby driving all the first abutment columns 3 to rotate synchronously, and at the same time, the first abutment columns 3 drive the adjacent threaded steel bars to rotate (the rotation directions of the two adjacent threaded steel bars are opposite), so that the threaded steel bars rotate continuously during the rust removal process, avoiding the blind spots of the threaded steel bars during the rust removal process, and achieving complete rust removal of the threaded steel bars. At the same time, the two adjacent threaded steel bars rub against each other during the rotation process, and the rust that has re-adhered to the surface of the threaded steel bars is cleaned, thereby further improving the cleanliness of the surface of the threaded steel bars.

[0062] In the above-mentioned process of rust removal of rebar, since the rebar is constantly rotating, the path swept by the laser rust remover for the same rebar is spiral (i.e., the rust removal path is spiral). After the laser rust remover moves forward to the limit position, the staff shuts down the drive module and controls the moving component at the same time to stop the laser rust remover from moving. Then the staff controls the drive module to drive all the rebars to rotate 90° (i.e., switch to another rust removal path). Then the staff controls the laser rust remover to move backward through the moving component, and controls the drive module to drive all the rebars to reverse, so that the laser rust remover performs rust removal on other parts of the rebar during the backward movement, avoiding the laser rust remover sweeping the same path on the same rebar during the backward movement and the forward movement, thereby causing incomplete rust removal of the rebar. When the laser rust remover moves backward to the initial position, the staff repeats the above operation to continue to remove rust on the rebar. After all the rust removal paths can be combined into a closed cylindrical shape, the rust removal operation is completed.

[0063] In the above process of fixing the rebar, the staff can adjust the rotation direction of the thread on the rebar to be the same as the moving direction of the laser rust remover, so that when the laser rust remover is removing rust from the rebar, the thread on the rebar is always in a position perpendicular to the laser rust remover, further reducing the blind area on the rebar during the rust removal process and increasing the completeness and uniformity of the rust removal of the rebar.

[0064] After the rust removal of a batch of threaded steel bars is completed, the staff controls the driving motor 4 to reset the movable shell 7, thereby loosening the fixation of the threaded steel bars. Subsequently, the staff uses the existing device to remove the threaded steel bars after rust removal, and places the next batch of threaded steel bars that need rust removal on the mounting frame 1, and repeats the above operation to perform rust removal on the new batch of threaded steel bars.

[0065] Further, such as Figure 1 , Figure 2 and Figure 6 As shown, the moving assembly includes: a second fixed plate 91, fixedly connected to the mounting frame 1; an electric shaft 92, arranged on the second fixed plate 91, and an external thread is arranged on the electric shaft 92. The electric shaft 92 is threadedly connected to a moving rod 93 through the external thread thereon, and the moving rod 93 passes through the second fixed plate 91 and is slidably connected thereto; a first electric push rod 94, fixedly connected to a side of the moving rod 93 away from the electric shaft 92, and the telescopic end of the first electric push rod 94 passes through the moving rod 93; a U-shaped frame 95, fixedly connected to the telescopic end of the first electric push rod 94, and the laser rust remover is installed on the U-shaped frame 95.

[0066] In the above scheme, the second fixed plate 91 is located at the right part of the upper side of the mounting frame 1; the electric rotating shaft 92 is located on the right side of the second fixed plate 91. During the rotation process, the electric rotating shaft 92 drives the moving rod 93 to move forward and backward along the second fixed plate 91 through the external thread thereon. Initially, the moving rod 93 is located at the rear part of the electric rotating shaft 92. The electric rotating shaft 92 rotates forward to drive the moving rod 93 to move forward. After the moving rod 93 moves forward to the limit position, the electric rotating shaft 92 reverses to drive the moving rod 93 to move backward; the first electric push rod 94 is located at the left end of the moving rod 93; the U-shaped frame 95 is composed of a horizontal part It is composed of two vertical parts, and the two vertical parts of the U-shaped frame 95 are located at the lower side of its horizontal part, and the laser rust remover is located at the lower side of the horizontal part of the U-shaped frame 95, so that when the movable rod 93 moves forward and backward, the laser rust remover is driven to move forward and backward synchronously through the first electric push rod 94 and the U-shaped frame 95 to change the rust removal position of the threaded steel; the height of the U-shaped frame 95 and the laser rust remover thereon is adjusted by changing the position of the telescopic end of the first electric push rod 94, that is, the distance between the laser rust remover and the threaded steel is adjusted, so that the laser rust remover can clean the rust on the surface of the threaded steel more efficiently.

[0067] Further, such as Figure 3-Figure 5 As shown, rubber blocks are installed on the facing sides of the first abutting column 3 and the second abutting column 9 to improve the fixing effect of the workpiece.

[0068] In the above scheme, rubber blocks are installed on the facing sides of the first abutment column 3 and the second abutment column 9, so that when the rubber blocks come into contact with the adjacent threaded steel bars, they are squeezed by the shape of the end portion of the threaded steel bars and deformed, thereby increasing the contact area with the threaded steel bars and improving the fixing effect on the threaded steel bars.

[0069] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 2 As shown, it also includes: a pressing mechanism, having two symmetrically distributed ones, both arranged on the second fixed plate 91, the pressing mechanism is used to press one end of the workpiece, and the pressing mechanism includes: a fixed rod 10, fixedly connected to the second fixed plate 91; an electric telescopic rod 11, installed on the fixed rod 10; a squeezing plate 13, fixedly connected to the telescopic end of the electric telescopic rod 11, and the squeezing plate 13 is used to press the workpiece.

[0070] In the above solution, the two pressing mechanisms are both located on the left side of the second fixing plate 91 and are symmetrically distributed front to back; the distance between the two squeezing plates 13 is smaller than the minimum distance between the first abutting column 3 and the second abutting column 9 .

[0071] After placing a batch of threaded steel bars on the mounting frame 1 as mentioned above, the staff starts the two electric telescopic rods 11, and the telescopic ends of the two electric telescopic rods 11 respectively drive the adjacent extrusion plates 13 to move downward to lower the height of the two extrusion plates 13. After the extrusion plates 13 move downward to contact the upper side of the threaded steel bars, the staff shuts down the two electric telescopic rods 11, and the two extrusion plates 13 cooperate with the mounting frame 1 to limit the batch of threaded steel bars in the up and down directions, and then starts the drive motor 4, and all the first abutment columns 3 and all the second abutment columns 9 clamp and fix all the threaded steel bars to avoid the situation where part of the threaded steel bars move in the process of clamping and fixing the threaded steel bars by the first abutment columns 3 and the second abutment columns 9, such as: if the end portion of a certain threaded steel bar is divided into inclined surfaces, and when the threaded steel bar is placed, the inclined surface of the end portion of the threaded steel bar happens to be placed up and down, then when the threaded steel bar is fixed, the threaded steel bar is easily squeezed by the first abutment column 3 or the second abutment column 9 and moves upward, resulting in a change in the position of the threaded steel bar, thereby causing the uniformity of its rust removal to decrease.

[0072] Further, such as Figure 1 and Figure 2 As shown, the extrusion plate 13 is provided with an arc groove for increasing the contact area between the extrusion plate 13 and the processing room.

[0073] In the above scheme, grooves are provided on the extrusion plate 13 so that each groove corresponds to the upper side surface of a threaded steel bar. While increasing the contact area between the extrusion plate 13 and the threaded steel bar, the threaded steel bar is also limited by the grooves to prevent the position of the threaded steel bar from moving during the above-mentioned rotation of the threaded steel bar.

[0074] Further, such as Figure 2 and Figure 6As shown, it also includes: two mounting rods 96 symmetrically distributed, both fixed to the U-shaped frame 95, the side of the mounting rod 96 away from the U-shaped frame 95 is rotatably connected to a rotating roller, and the two mounting rods 96 are respectively located on both sides of the laser rust remover.

[0075] In the above scheme, the two mounting rods 96 are respectively located at the lower sides of the two vertical parts of the U-shaped frame 95; initially, the front mounting rod 96 is located behind the second abutment column 9, and when the extrusion plate 13 is at the highest point, the lower side of the extrusion plate 13 is higher than the upper side of the first electric push rod 94, ensuring that the first electric push rod 94 will not collide with the extrusion plate 13 during the forward and backward movement.

[0076] After the rebar is pressed and fixed by the two extrusion plates 13, the staff operates according to the above-mentioned operation, and in the process of lowering the height of the U-shaped frame 95, the U-shaped frame 95 drives the two mounting rods 96 to move downward synchronously, thereby driving the rotating rollers on the mounting rods 96 to move downward (in this process, the electric shaft 92 rotates forward, causing the two mounting rods 96 to move forward). When the mounting rod 96 on the front side contacts the upper side of the rebar, the staff turns off the first electric push rod 94 and controls the electric telescopic rod 11 on the rear side to reset the extrusion plate 13 on the rear side to the initial position upward to avoid the extrusion plate 13 from affecting the normal movement of the moving rod 93. At the same time, it also avoids the contact between the extrusion plate 13 and the rebar, which causes the rebar to be blocked, resulting in incomplete rust removal of the rebar and affecting the subsequent normal use of the rebar. Subsequently, the staff performs rust removal on the rebar according to the above-mentioned operation, and the rotating roller on the mounting rod 96 replaces the extrusion plate 13 on the rear side to press the rebar.

[0077] During the above-mentioned rust removal operation on the threaded steel bar, after the rear mounting rod 96 moves forward to the front side of the rear extrusion plate 13, the staff controls the rear extrusion plate 13 to move to a position in contact with the threaded steel bar again to press the rear end of the threaded steel bar.

[0078] During the above-mentioned process of derusting the threaded steel bar, until the front extrusion plate 13 moves forward to a position close to the front extrusion plate 13, the staff changes the position of the front extrusion plate 13 according to the above-mentioned operation. When the moving rod 93 moves forward to the limit position, the staff controls the electric shaft 92 to drive the moving rod 93 to move backward, and repeats the above-mentioned operation to adjust the positions of the two extrusion plates 13 in turn.

[0079] After a batch of threaded steel bars are derusted, the staff controls the two extrusion plates 13 to move upward to the initial position, and replaces the derusted threaded steel bars according to the above operation, and continues the derusting operation.

[0080] Embodiment 3: Based on embodiment 4, Figure 4 and Figure 5As shown, it also includes: fixed blocks 16, the number of which is consistent with the number of second abutment columns 9, both of which are slidably connected in the movable shell 7, the fixed blocks 16 are rotatably connected to the adjacent second abutment columns 9, the second abutment columns 9 are slidably connected to the movable shell 7, and a plurality of small steel balls are stored in the movable shell 7.

[0081] In the above scheme, the small steel ball in the moving shell 7 is an existing device, which is not shown in the figure. Initially, the small steel ball in the moving shell 7 has space for movement; in the process of the output shaft of the above-mentioned driving motor 4 driving the moving shell 7 to move forward through the parts connected thereto, the moving shell 7 drives the fixed block 16 and the second abutment column 9 to move forward synchronously through the squeezing of the steel ball therein. When the second abutment column 9 moves forward to contact with the rear end of the adjacent threaded steel bar, the second abutment column 9 pushes the adjacent threaded steel bar to move forward. After the front end of the threaded steel bar contacts with the adjacent first abutment column 3, the threaded steel bar can no longer move forward. At this time, the threaded steel bar reacts to the adjacent second abutment column 9, causing the first abutment column 3 to move forward. The second abutment column 9 cannot move forward. When the moving shell 7 continues to move forward, the stopped second abutment column 9 drives the fixed block 16 thereon to move backward relative to the moving shell 7, thereby squeezing the steel balls in the moving shell 7, causing the positions of the steel balls in the moving shell 7 to change, thereby making the front sides of all the second abutment columns 9 no longer in the same vertical line, so as to cope with threaded steel bars of different lengths and adaptively fix the threaded steel bars, and at the same time push the front ends of all the threaded steel bars to be on the same vertical plane (even if the front ends of the threaded steel bars are flush, the rear ends are uneven due to the length of the threaded steel bars), until all the threaded steel bars are fixed, and then the staff turns off the drive motor 4.

[0082] Furthermore, Figure 3 , Figure 4 and Figure 7-Figure 9 As shown, it also includes: a reinforcement mechanism, which is arranged on the mounting frame 1, and the reinforcement mechanism is used to increase the fixing effect of the workpiece when it is turned over. The reinforcement mechanism includes: a second electric push rod 17, which has two symmetrically distributed ones, both of which are fixed to the mounting frame 1, and the telescopic end of the second electric push rod 17 is fixedly connected to a second movable plate 18, and the second movable plate 18 slides on the mounting frame 1, and the second movable plate 18 is provided with through holes with the same number as the first abutment column 3, and the first abutment column 3 and the second abutment column 9 are respectively located in the adjacent through holes on the adjacent second movable plate 18, and the first abutment column 3 and the second abutment column 9 are both slidably connected with a fixing ring 19; the first elastic member 191, the number of which is the same as the number of the fixing ring 19, is respectively fixed between the adjacent fixing ring 19 and the adjacent second movable plate 18, and the fixing ring 19 is fixed with a symmetrically distributed extrusion block 20, and the fixing ring 19 is provided with a spline groove, and the first abutment column 3 and the second abutment column 9 are both provided with a spline portion for driving the adjacent fixing ring 19 to rotate.

[0083] In the above scheme, the two second electric push rods 17 are respectively located at the front and rear parts of the upper left side of the mounting frame 1; the diameter of the through hole on the second movable plate 18 is larger than the diameter of the first abutment column 3; initially, the fixing ring 19 is not spline-connected with the adjacent first abutment column 3 or the adjacent second abutment column 9; the first elastic member 191 is a torsion spring; the extrusion block 20 is made of elastic deformable material, which is used to be deformed by the extrusion of the threaded steel bar to increase the contact area between the extrusion block 20 and the threaded steel bar; the two extrusion blocks 20 on the same fixing ring 19 are initially placed at an angle.

[0084] When the threaded steel bar needs to be rotated, the staff intermittently starts the two second electric push rods 17, and the telescopic ends of the two second electric push rods 17 drive the two second moving plates 18 to move. The following is described by taking the moving process of the front second moving plate 18 as an example:

[0085] The second movable plate 18 drives the fixing ring 19 to move backward synchronously through the first elastic member 191 thereon, so that the fixing ring 19 is spline-connected with the spline portion on the adjacent first abutting column 3, and the fixing ring 19 drives the two extrusion blocks 20 thereon to move synchronously until the extrusion block 20 moves to contact the adjacent threaded steel bar. During the continued movement of the extrusion block 20, the extrusion block 20 is deformed by the extrusion of the adjacent threaded steel bar. At the same time, the two extrusion blocks 20 on the same fixing ring 19 clamp the front end of the threaded steel bar to increase the fixing force on the threaded steel bar, thereby preventing the threaded steel bar from slipping against the first abutting column 3 and the second abutting column 9 during rotation, thereby causing the rotation angle of the threaded steel bar to deviate from the predetermined angle, resulting in a decrease in the rust removal effect of the threaded steel bar.

[0086] After the second movable plate 18 moves backward to the extreme position, the staff stops the second electric push rod 17. At this time, the front fixing ring 19 contacts the front end of the adjacent threaded steel bar. Then the staff controls the driving module to drive the first abutment column 3 to rotate. The first abutment column 3 drives the adjacent fixing ring 19 to rotate through the spline portion thereon. The fixing ring 19 drives the two adjacent extrusion blocks 20 to rotate synchronously, thereby driving the adjacent threaded steel bars to rotate synchronously, thereby realizing the operation of changing the position of the threaded steel bars.

[0087] During the rotation of the above-mentioned fixing ring 19, the fixing ring 19 causes the adjacent first elastic member 191 to twist and accumulate force. After driving all the threaded steel bars to rotate 90°, the staff stops the driving module and drives the second movable plate 18 to move forward through the second electric push rod 17, so that the second movable plate 18 drives the adjacent fixing ring 19 to move forward. After the fixing ring 19 is separated from the spline part on the adjacent first abutting column 3, the first elastic member 191 drives the adjacent fixing ring 19 to rotate in the opposite direction, and then the fixing ring 19 drives the two adjacent extrusion blocks 20 to rotate in the opposite direction and reset for subsequent continued use.

[0088] Furthermore, Figure 8 and Fig. 9 As shown, the extrusion block 20 is provided with a storage cavity, and a liquid capsule 21 is installed in the storage cavity of the extrusion block 20. All the liquid capsules 21 close to the same second movable plate 18 are connected to each other by a hose.

[0089] After the extrusion block 20 moves to the extreme position, the staff uses the existing pumping device to synchronously deliver hydraulic oil to all the liquid bags 21 through two hoses to expand the liquid bags 21, thereby increasing the clamping force of the extrusion block 20 on the adjacent threaded steel bars. After driving the threaded steel bars to rotate, the staff uses the existing pumping device to extract the hydraulic oil delivered to the liquid bags 21 for subsequent continued use.

[0090] Embodiment 4: Based on embodiment 3, Figure 3 , Figure 7 and Figure 10-12 As shown, it also includes: a conveyor belt 22, having two symmetrically distributed ones, which are respectively installed on one side of the mounting frame 1, and the two conveyor belts 22 cooperate with each other to transport the workpiece, and a plurality of limit blocks 23 are arranged on the conveyor belt 22; two support blocks 24, which are symmetrically distributed, are both fixed to the mounting frame 1, and the support blocks 24 are located inside the adjacent conveyor belts 22; a guide block 25, which is fixed to one side of the mounting frame 1 close to the second fixed plate 91; two limit columns 26, which are symmetrically distributed, are both slidably connected to the mounting frame 1, and a second elastic member 27 is fixed between the limit column 26 and the mounting frame 1.

[0091] In the above scheme, the two conveyor belts 22 are symmetrically distributed front and back, and the two conveyor belts 22 are driven by the existing driving device (not shown in the figure). The height of the upper side of the conveyor belt 22 is higher than the upper side of the mounting frame 1 to avoid direct contact between the threaded steel and the mounting frame 1; the opposite sides of the two adjacent limit blocks 23 are provided with arc surfaces for positioning the threaded steel. The positions and number of the limit blocks 23 in the figure are only examples. In actual use, the number and position of the limit blocks 23 can be specifically selected by the staff; the upper side of the support block 24 contacts the upper side of the adjacent conveyor belt 22 to support the threaded steel on the adjacent conveyor belt 22; the guide block 25 is located on the right side of the mounting frame 1, and the height of the uppermost side of the guide block 25 is higher than the conveyor belt 22. The figure and the text take two guide blocks 25 as an example, and the upper side of the guide block 25 is provided with an inclined surface; the distance between the second fixed plate 91 and the opposite side of the guide block 25 is equal to the diameter of the threaded steel; the limit column 26 is located between the second fixed plate 91 and the guide block 25; the second elastic member 27 is a tension spring.

[0092] In the above-mentioned process of transporting the threaded steel, the staff uses the existing conveying device to transport the threaded steel to between the second fixed plate 91 and the two guide blocks 25, and moves the threaded steel downward between the second fixed plate 91 and the two guide blocks 25 until the threaded steel moves downward to contact with both limit posts 26. The threaded steel squeezes the two limit posts 26, so that the two limit posts 26 move downward synchronously, and the two second elastic members 27 are stretched and stored synchronously. When the threaded steel moves downward to the limit position, the threaded steel is located between the two limit blocks 23 and contacts with the arc surfaces on the two limit blocks 23 at the same time. When the limit column 26 moves downward to the limit position, the two second elastic members 27 jointly buffer the threaded steel bar and slow down the speed at which the threaded steel bar moves downward, thereby ensuring that the threaded steel bar can accurately fall between the two limit blocks 23, and at the same time ensuring that the threaded steel bar can be in a position parallel to the vertical surface of the second fixing plate 91 after falling between the two limit blocks 23, to avoid the threaded steel bar deviating due to the large impact force generated when the threaded steel bar contacts the two limit blocks 23 due to the thread moving downward too fast, thereby affecting the fixing effect of the first abutment column 3 and the adjacent second abutment column 9 on the same threaded steel bar.

[0093] After the two limit columns 26 are moved downward to the extreme positions, the staff drives the two conveyor belts 22 to rotate synchronously through the existing driving device to transport the rebars on the conveyor belts 22 to the left. Then the staff places the batch of rebars on the conveyor belts 22 in turn according to the above operations, and the conveyor belts 22 transport the batch of rebars to the rust removal position, and then the rebars are derusted according to the above operations.

[0094] In the process of the two conveyor belts 22 driving the threaded steel bars thereon to move, after the threaded steel bars lose contact with the two limiting posts 26 , the limiting posts 26 are reset upward to the initial position under the action of the second elastic member 27 for subsequent use.
