Description

Technical Field

[0001] The invention relates to the technical field of pipe segment reinforcement cage production, and in particular to an integrated automatic forming production line for pipe segment reinforcement cages. Background Art

[0002] The segment steel cage is an important component used to make reinforced concrete segments in tunnels, subways and other projects. The simple segment steel cage structure is composed of internal longitudinal bars (i.e., the arc-shaped skeleton inside the segment) and stirrups (i.e., the inverted U-shaped outer stirrups) welded together at a specific spacing to form a complete grid structure. The segment steel cage is usually pre-made and transported to the construction site for installation and pouring of concrete, which greatly improves the construction efficiency. In the actual welding process of the segment steel cage, multiple groups of internal longitudinal bars and stirrups need to be assembled before welding, which requires the internal longitudinal bars to be loaded one by one, and the height of the internal longitudinal bars is gradually raised. Due to the heavy weight of the internal longitudinal bars and stirrups, it is very troublesome to load the internal longitudinal bars and raise the height after loading. It is difficult to ensure that the internal longitudinal bars and stirrups are evenly spaced by manual operation alone, and the subsequent welding quality cannot be guaranteed. For this reason, we have launched an integrated automatic forming production line for segment steel cages. Summary of the invention

[0003] The object of the present invention is to provide an automatic forming production line for integrated segment reinforcement cage to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An integrated automatic forming production line for a pipe segment reinforcement cage comprises a base, wherein the upper end of the base is provided with a plurality of rollers for supporting an inner arc-shaped skeleton of the pipe segment, a plurality of inverted U-shaped external stirrups are inserted into a groove in the middle of the upper end of the base, and the inverted U-shaped external stirrups are arranged between adjacent rollers;

[0006] The base is fixed with vertical seats on both sides of the front and rear ends, and a vertical rack is slidably connected inside the vertical seat. The support plate installed on the side of the vertical rack extends through the vertical slot provided on the inner wall of the vertical seat;

[0007] The vertical seat is also provided with a first gear meshing with the corresponding vertical rack, and a rotating rod is connected between the front and rear first gears;

[0009] When the inner arc frame of the segment is pushed backward along the roller and makes the inner arc frame of the segment contact with the buffer mechanism, the buffer mechanism plays a buffering role in the backward movement of the inner arc frame of the segment. At the same time, the buffer mechanism also drives the clutch mechanism to connect with the power unit, so that the power unit drives the rotating rod to rotate through the clutch mechanism and the transmission mechanism, so that the first gear drives the support plate to move up through the vertical rack, and the inner arc frame of the segment and the inverted U-shaped outer stirrup are raised in height;

[0010] Subsequently, when the arc-shaped skeleton in the pipe segment is out of contact with the buffer mechanism, the buffer mechanism is reset, so that the clutch mechanism is disconnected from the power unit.

[0011] Preferably, brackets are provided on the left and right sides of the groove in the middle of the upper end of the base, the roller is installed between the left and right brackets, and the plurality of groups of rollers distributed front and back are distributed at equal intervals.

[0012] Preferably, the front and rear ends of the rotating rod penetrate into the corresponding vertical seat and are fixed to the middle part of the first gear;

[0013] The transmission mechanism includes a second gear whose rear end of the rotating rod extends into the box and is then fixed, a third gear connected to the inner side of the second gear by a chain, a fourth gear fixed to the middle of the rear end of the third gear by a rotating shaft, and a group of cross clamps fixed to the rear end of the rotating shaft;

[0014] The two sets of fourth gears mesh with each other.

[0015] Preferably, the clutch mechanism comprises a rotating drum inside the housing, a first friction disc installed at the front end of the rotating drum, a support seat movably connected to the rear of the L-shaped frame through a pin, and a toggle seat connected to the lower end of the support seat;

[0016] Preferably, the bottom of the toggle seat extends into the interior of the box through the slot on the top of the box, the cross clamp passes through the notch at the lower end of the toggle seat and is inserted into the cross slot in the middle of the front end of the rotating drum, and the front end of the rotating drum is also provided with a first spring sleeved on the outside of the corresponding rotating shaft.

[0017] An arc-shaped protrusion is arranged at the rear end of the bottom of the shifting seat, and the arc-shaped protrusion abuts against the front end of the rotating drum.

[0018] Preferably, the upper and lower ends of the first friction disc are provided with limiting protrusions, the middle part of the front end of the rotating drum is provided with an opening slot for inserting the first friction disc, and a second spring is connected between the front end of the first friction disc and the opening slot;

[0019] The upper and lower walls of the opening slot are provided with limiting slide grooves, and the limiting protrusions extend through the corresponding limiting slide grooves;

[0020] The rear end of the rotating drum is fixed with a limiting ring seat by bolts, and the rear end of the first friction disc extends through the middle part of the limiting ring seat.

[0021] Preferably, the buffer mechanism comprises a buffer cylinder fixed between the front parts of the L-shaped frame, a piston disc slidably connected inside the buffer cylinder, a support rod fixed at the middle part of the piston disc, a support plate fixed after the front end of the support rod extends out of the buffer cylinder, and a third spring provided inside the buffer cylinder and sleeved on the outside of the support rod;

[0022] The front end of the third spring is fixed to the rear end of the piston disc, and the rear end of the abutment rod extends out of the buffer cylinder and then is inserted into the abutment groove at the front end of the abutment seat.

[0023] Preferably, the power unit includes a motor fixed at the rear end of the housing and a second friction disc fixed after the motor shaft at the output end of the motor extends into the housing, and the second friction disc is located directly behind the first friction disc.

[0024] Preferably, a curved brake pad is provided at the lower interior of the box, and an electric telescopic rod is installed at the lower end of the box. The piston rod of the electric telescopic rod extends into the interior of the box and is fixedly connected to the middle part of the lower end of the curved brake pad.

[0025] Preferably, the inner wall of the vertical rack is provided with support protrusions which are evenly spaced up and down, and the support plate is movably connected to the upper ends of the corresponding support protrusions through pins.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: when the present invention pushes the inner arc frame of the segment backward along the roller and makes the inner arc frame of the segment contact with the buffer mechanism, the buffer mechanism plays a buffering role in the backward movement of the inner arc frame of the segment. At the same time, the buffer mechanism also drives the clutch mechanism to connect with the power unit, so that the power unit drives the rotating rod to rotate through the clutch mechanism and the transmission mechanism, so that the first gear drives the support plate to move upward through the vertical rack, and the inner arc frame of the segment and the inverted U-shaped outer stirrup are raised in height;

[0027] Subsequently, when the arc-shaped skeleton inside the segment is out of contact with the buffer mechanism, the buffer mechanism is reset, so that the clutch mechanism is disconnected from the power unit. Then, the above operation can be repeated to gradually raise the height of the new arc-shaped skeleton inside the segment until several groups of arc-shaped skeletons inside the segment are evenly spaced up and down, and the inverted U-shaped external hoop reinforcement is stuck on the outside of several groups of arc-shaped skeletons inside the segment, which is conducive to the subsequent use of a welding robot to weld the connection between the inverted U-shaped external hoop reinforcement and the arc-shaped skeleton inside the segment. Such operation makes the loading of the arc-shaped skeleton inside the segment simple, and after loading, the arc-shaped skeleton inside the segment can be lifted one by one, which is simpler and more labor-saving.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Example:

[0045] See also Figure 1-14 , the present invention provides a technical solution:

[0046] An integrated automatic forming production line for a pipe segment reinforcement cage includes a base 12. The upper end of the base 12 is provided with a plurality of groups of rollers 14 for supporting an arc-shaped skeleton 17 in the pipe segment. Brackets 13 are provided on the left and right sides of a groove in the middle of the upper end of the base 12. The rollers 14 are installed between the left and right brackets 13, and the plurality of groups of rollers 14 distributed front and back are distributed at equal intervals.

[0047] A plurality of inverted U-shaped external stirrups 16 are inserted into the groove in the middle of the upper end of the base 12. Under the elastic force of the inverted U-shaped external stirrups 16, the side edges of the inverted U-shaped external stirrups 16 can be tightened and closely attached to the inner wall of the groove in the middle of the upper end of the base 12, thereby achieving the fixation of the inverted U-shaped external stirrups 16.

[0048] And the inverted U-shaped outer stirrup 16 is arranged between adjacent rollers 14;

[0049] A vertical seat 10 is fixed on both sides of the front and rear ends of the base 12. A vertical rack 8 is slidably connected inside the vertical seat 10. A support plate 9 installed on the side of the vertical rack 8 extends through a vertical slot 11 provided on the inner wall of the vertical seat 10.

[0050] like Fig.13 and 14 As shown, the inner wall of the vertical rack 8 is provided with support protrusions 81 distributed at equal intervals up and down, and the support plate 9 is movably connected to the upper end of the corresponding support protrusion 81 through a pin 82.

[0051] A first gear 7 meshing with the corresponding vertical rack 8 is also provided inside the vertical seat 10, and a rotating rod 6 is connected between the front and rear first gears 7;

[0052] The front and rear ends of the rotating rod 6 penetrate into the corresponding vertical seat 10 and are fixed to the middle of the first gear 7;

[0053] The transmission mechanism 5 includes a second gear 506 fixed after the rear end of the rotating rod 6 extends into the box body 15, a third gear 503 connected to the inner side of the second gear 506 by a chain 505, a fourth gear 501 fixed to the middle of the rear end of the third gear 503 by a rotating shaft 502, and a group of cross clamps 504 fixed to the rear end of the rotating shaft 502;

[0054] The two sets of fourth gears 501 mesh with each other.

[0055] A box 15 is fixed between the rear parts of the two sets of vertical seats 10 at the rear end, and a power unit 1 is installed at the rear part of the box 15;

[0056] The power unit 1 includes a motor 101 fixed at the rear end of the housing 15 and a second friction disc 102 fixed after the motor shaft 103 at the output end of the motor 101 extends into the housing 15, and the second friction disc 102 is located directly behind the first friction disc 203. The PLC controller controls the motor 101 to work, so that the motor 101 drives the second friction disc 102 to rotate through the motor shaft 103;

[0057] The housing 15 is also provided with a clutch mechanism 2 located in front of the power unit 1;

[0058] The clutch mechanism 2 includes a rotating drum 206 inside the housing 15, a first friction disc 203 installed at the front end of the rotating drum 206, a support seat 210 movably connected between the rear part of the L-shaped frame 4 through a pin 212, and a toggle seat 213 connected to the lower end of the support seat 210;

[0059] The bottom of the toggle seat 213 extends into the interior of the box body 15 through the slot 151 at the top of the box body 15, and the cross clamping plate 504 passes through the notch 214 at the lower end of the toggle seat 213 and is inserted into the cross slot 208 in the middle of the front end of the rotating cylinder 206. The front end of the rotating cylinder 206 is also provided with a first spring 209 which is sleeved on the outside of the corresponding rotating shaft 502.

[0060] The rear end of the bottom of the toggle seat 213 is provided with an arc-shaped protrusion 215, which abuts against the front end of the rotating drum 206. The arc-shaped protrusion 215 reduces the contact area between the rear end of the bottom of the toggle seat 213 and the front end of the rotating drum 206. When the rotating drum 206 rotates, the friction on the rear end of the bottom of the toggle seat 213 is reduced, and the resistance to the rotation of the rotating drum 206 is also reduced.

[0061] The first friction disc 203 is provided with limit protrusions 204 at the upper and lower ends, and the front end of the rotating cylinder 206 is provided with an opening slot 2061 for inserting the first friction disc 203, and a second spring 205 is connected between the front end of the first friction disc 203 and the opening slot 2061;

[0062] The upper and lower walls of the opening groove 2061 are provided with limiting grooves 207, and the limiting protrusions 204 extend through the corresponding limiting grooves 207; such a configuration enables the first friction disc 203 to drive the rotating drum 206 to rotate when the second friction disc 102 drives the first friction disc 203 to rotate, and when the first friction disc 203 moves forward and backward relative to the rotating drum 206, the limiting protrusions 204 slide along the limiting grooves 207, so that the first friction disc 203 moves forward and backward relative to the rotating drum 206 smoothly and stably;

[0063] The rear end of the rotating drum 206 is fixed to the limiting ring seat 201 by bolts 202 , and the rear end of the first friction disc 203 extends through the middle of the limiting ring seat 201 .

[0064] The front of the clutch mechanism 2 is connected to the rear end of the rotating rod 6 through the transmission mechanism 5, and the upper end of the box body 15 is installed with a buffer mechanism 3 through the L-shaped frame 4;

[0065] The buffer mechanism 3 includes a buffer cylinder 302 fixed between the front parts of the L-shaped frame 4, a piston plate 304 slidingly connected inside the buffer cylinder 302, a support rod 301 fixed in the middle of the piston plate 304, a support plate 303 fixed after the front end of the support rod 301 extends out of the buffer cylinder 302, and a third spring 305 provided inside the buffer cylinder 302 and sleeved on the outside of the support rod 301;

[0066] The front end of the third spring 305 is fixed to the rear end of the piston plate 304 , and the rear end of the abutting rod 301 extends out of the buffer cylinder 302 and is inserted into the abutting groove 211 at the front end of the abutting seat 210 .

[0067] When the inner arc frame 17 of the segment is pushed backward along the roller 14 and makes the inner arc frame 17 contact with the buffer mechanism 3, the buffer mechanism 3 plays a buffering role in the backward movement of the inner arc frame 17 of the segment. At the same time, the buffer mechanism 3 also drives the clutch mechanism 2 to connect with the power unit 1, so that the power unit 1 drives the rotating rod 6 to rotate through the clutch mechanism 2 and the transmission mechanism 5, so that the first gear 7 drives the support plate 9 to move upward through the vertical rack 8, and the inner arc frame 17 of the segment and the inverted U-shaped outer stirrup 16 are raised.

[0068] Subsequently, when the arc-shaped skeleton 17 in the pipe segment is out of contact with the buffer mechanism 3 , the buffer mechanism 3 is reset, so that the clutch mechanism 2 is disconnected from the power unit 1 .

[0069] like Fig.11 As shown, an arc-shaped brake pad 18 is also provided at the lower part of the box body 15 , and an electric telescopic rod 19 is installed at the lower end of the box body 15 . The piston rod of the electric telescopic rod 19 extends into the box body 15 and is fixedly connected to the middle part of the lower end of the arc-shaped brake pad 18 .

[0070] Specifically, when in use, the inner arc-shaped frame 17 of the segment is pushed backward along the roller 14, so that the inner arc-shaped frame 17 of the segment moves backward along the inside of the front and rear groups of inverted U-shaped external stirrups 16, and the rear end of the inner arc-shaped frame 17 of the segment contacts the abutting plate 303;

[0071] The abutment plate 303 drives the abutment rod 301 and the piston plate 304 to move backwards. When the piston plate 304 moves backwards along the inside of the buffer cylinder 302, the third spring 305 is gradually in a compressed state. Therefore, under the elastic force of the third spring 305 on the piston plate 304, when the rear end of the inner arc-shaped skeleton 17 of the tube segment contacts the abutment plate 303, the entire buffer mechanism 3 plays a buffering role on the inner arc-shaped skeleton 17 of the tube segment.

[0072] like Fig. 9 As shown, the abutment plate 303 pushes the abutment seat 210 to rotate counterclockwise with the pin shaft 212 as the center through the abutment rod 301, so that the toggle seat 213 pushes the rotating cylinder 206 to move backward along the cross clamping plate 504 (at this time, the first spring 209 is in a gradually stretched state), so that when the first friction disc 203 and the front end of the second friction disc 102 just come into contact, at this time, the first friction disc 203 moves into the opening groove 2061, and the second spring 205 is in a compressed state. The second spring 205 is set to play a buffering role when the front ends of the first friction disc 203 and the second friction disc 102 just come into contact;

[0073] like Figure 6As shown, until the first friction disc 203 is in close contact with the front end of the second friction disc 102, at this time, the motor 101 drives the first friction disc 203 to rotate through the second friction disc 102, and the first friction disc 203 drives the fourth gear 501 and the third gear 503 on the rotating shaft 502 to rotate through the rotating cylinder 206, the cross clamping plate 504 and the rotating shaft 502;

[0074] Since the two sets of fourth gears 501 are meshed with each other, the third gears 503 on the two sets of rotating shafts 502 rotate synchronously, so that the third gear 503 drives the second gear 506 to rotate through the chain 505, and the second gear 506 drives the first gear 7 to rotate through the rotating rod 6, and the first gear 7 drives the support plate 9 to move upward through the vertical rack 8, so that the support plate 9 pushes the inner arc frame 17 of the pipe segment on the drum 14 upward, and the inner arc frame 17 of the pipe segment is raised with the inverted U-shaped outer stirrup 16;

[0075] like Fig.10 As shown, subsequently, when the rear end of the arc-shaped skeleton 17 in the tube segment is out of contact with the abutment plate 303, under the elastic force of the third spring 305 on the piston disc 304, the piston disc 304 moves forward with the abutment rod 301 and the abutment plate 303 to reset;

[0076] At this time, under the pulling force of the first spring 209 on the rotating drum 206, the rotating drum 206 moves forward along the cross clamping plate 504 to reset, and the rotating drum 206 pushes the toggle seat 213 to make the abutting seat 210 rotate clockwise around the pin shaft 212 to reset;

[0077] At the same time, after the rotating drum 206 moves forward and resets, the first friction disc 203 behind the rotating drum 206 is separated from the contact with the second friction disc 102, so that the second friction disc 102 no longer drives the first friction disc 203 to rotate, and the clutch mechanism 2 is disconnected from the power unit 1;

[0078] At the same time, the lower support plate 9 moves to a position slightly lower than the top of the roller 14 when the vertical rack 8 moves upward, so that after repeating the above operation on the arc-shaped frame 17 in the next segment, the lower support plate 9 raises the arc-shaped frame 17 in the segment.

[0079] By repeating the above operation, the arc-shaped skeletons 17 of the several groups of segments can be evenly spaced vertically, and the inverted U-shaped outer stirrups 16 can be stuck on the outer sides of the arc-shaped skeletons 17 of the several groups of segments (such as Fig.12 status shown);

[0080] Then, a welding robot is used to weld the connection between the inverted U-shaped outer stirrup 16 and the inner arc-shaped skeleton 17 of the pipe segment;

[0081] like Fig.11As shown, after the clutch mechanism 2 is disconnected from the power unit 1, the PLC controller controls the piston rod of the electric telescopic rod 19 to extend, so that the arc-shaped brake pad 18 is tightly attached to the bottom of the rotating drum 206, thereby achieving a braking effect on the rotating drum 206, and the rotating drum 206 stops rotating, so that the rotating drum 206, the transmission mechanism 5, the rotating rod 6 and the first gear 7 are all in a stationary state, thereby preventing the vertical rack 8 from moving downward under the pressure of the arc-shaped skeleton 17 and the inverted U-shaped outer stirrup 16 in the segment on the support plate 9, thereby preventing the arc-shaped skeleton 17 and the inverted U-shaped outer stirrup 16 in the segment from decreasing in height.

[0082] After the inverted U-shaped outer stirrups 16 and the inner arc-shaped frame 17 of the segment are welded to form the segment reinforcement cage, the support plate 9 on the front vertical rack 8 is rotated outward so that the support plate 9 is out of contact with the inner arc-shaped frame 17 of the segment (such as Fig.14 As shown), the segment steel cage is then dragged forward, so that the segment steel cage moves forward along the roller 14 and then the segment steel cage is separated from the base 12, so that the segment steel cage can be subsequently processed and concrete poured and cured.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
