Description

TECHNICAL FIELD

[0001] The present application relates to the field of pile foundation steel bar welding equipment, in particular to a pile foundation steel reinforcement cage welding equipment for road and bridge construction. BACKGROUND

[0002] In modern road and bridge engineering construction, pile foundation as the basic structure of bridge and road, its construction quality directly determines the stability and safety of the whole project, steel reinforcement cage as the core component of pile foundation, needs to connect multiple main reinforcement and stirrup into a cage structure with specific strength and shape through welding process, therefore the performance of steel reinforcement cage welding equipment plays a key role in the quality of pile foundation.

[0003] When the existing close-range straight winding and straight welding method is adopted, the winding is bent on the main reinforcement in the process, and the winding is bent to form a bending point due to stress. When the bent winding is pressed and adhered to the main reinforcement, the main reinforcement will also deform after being stressed. If the pressure is too large, the main reinforcement will be stressed too much and will deform, thereby damaging the structure of the main reinforcement. If the pressure is too small, the bent winding and the main reinforcement cannot be fully adhered, which causes a gap between the bending point of the winding and the main reinforcement during the welding process of the winding and the main reinforcement, reduces the fusion core bonding area, and causes the welding to be not firm, thereby affecting the overall stability of the pile foundation.

DETAILED DESCRIPTION

[0036] Please refer to Figures 1 to 12 , the present application provides a kind of pile foundation steel reinforcement cage welding equipment for road and bridge construction technical scheme:

[0037] The utility model provides a kind of pile foundation reinforcement cage welding equipment for road and bridge construction, including main reinforcement 17 and around reinforcement 18, and hollow through welding box 5 and welding material bin 501 located above one side of welding box 5, further include: the introduction mechanism 20 and the lead-out mechanism 25 located inside the hollow through welding box 5 two sides, the inside of introduction mechanism 20 and lead-out mechanism 25 are all embedded with the horizontal lead-out roller 2501 and vertical lead-out roller 2502 that are set with the outer surface of around reinforcement 18, high-frequency heater 19 is fixedly installed in the middle of introduction mechanism 20 and lead-out mechanism 25, vibration generator 23 is fixedly installed on one side of lead-out mechanism 25 for generating vibration, vibration guide plate 24 is fixedly connected on vibration generator 23, and the end of vibration guide plate 24 is provided with fixedly installed power connection head 2201 that is set with main reinforcement 17 on the upper side of lead-out mechanism 25, power brush 22 is fixedly installed on the lower side of one side of welding material bin 501 and is set with around reinforcement 18, and the lower side of power brush 22 is provided with guide plate 505 that is fixedly installed in the lower side of welding material bin 501 and is set with inclination, sliding plate 502 is embedded in the inside of welding material bin 501, and the lower side of sliding plate 502 is fixedly installed with inclined plate 5021, auxiliary sending mechanism 21 is fixedly installed in the inside of welding box 5 on the other side of lead-out mechanism 25, and auxiliary sending mechanism 21 includes fixedly installed limit frame 2104 set on both sides of welding box 5, and limit frame 2104 is fixedly installed with close-to-rotation wheel 2101 in the inside, and spring rod two 2102 is installed on the upper and lower ends of close-to-rotation wheel 2101 on limit frame 2104, and telescopic rod 2103 is embedded and movably installed on one side of both limit frame 2104.

[0038] As an embodiment of the utility model, as shown in the figure, Figures 6 to 12 Around reinforcement 18 is set in the inside of high-frequency heater 19, one end of vibration guide plate 24 is arc-shaped and set with the outside of main reinforcement 17, around reinforcement 18 is movably set in the middle below guide plate 505, spring rod one 503 is fixedly installed in the inside of welding material bin 501, one end of spring rod one 503 is fixedly connected with sliding plate 502, inclined plate 504 is fixedly installed in the lower side of the inside of welding material bin 501, sliding plate 502 is movably set below inclined plate 504, power brush 22 and power connection head 2201 are telescopic spring rods, close-to-rotation wheel 2101 is tightly and closely set with around reinforcement 18, spring rod two 2102 is filled with hydraulic oil, the lower end of telescopic rod 2103 is flush with hydraulic oil, and inclined plate 5021 is transmission connected with the upper end of telescopic rod 2103.

[0039] In operation, the winding wire 18 is conveyed through the auxiliary conveying mechanism 21, the leading-in mechanism 20 and the leading-out mechanism 25 under the rotating conveying force of the main wire 17, is limitedly led into the welding box 5 through the leading-in mechanism 20, then enters the high-frequency heater 19 for heat treatment to eliminate the stress in the winding wire 18 and preheat, and facilitates the subsequent resistance hot melting butt welding and plastic shaping winding cage use, then the winding wire 18 passes through the auxiliary conveying mechanism 21, is output from the welding box 5 through the leading-out mechanism 25, and is bent to be attached to the main wire 17, and then the winding wire 18 is conveyed and output in the leading-in mechanism 20 and the leading-out mechanism 25 in the welding box 5 through the horizontally leading-out roller 2501 and the vertically leading-out roller 2502 which are embedded and movably arranged in the leading-in mechanism 20 and the leading-out mechanism 25;

[0040] Due to the close fit of the fitting rotating wheel 2101 in the limiting frame 2104 under the elastic pressure of the spring rod two 2102 tightly covering the winding wire 18, the winding wire 18 moves to drive the fitting rotating wheel 2101 to rotate synchronously. When the winding wire 18 is locally bent, the bending point of the winding wire 18 pushes the rotating wheel on one side to make the spring rod two 2102 compress. At this time, the pressure received by the fitting rotating wheel 2101 is transmitted to the hydraulic oil through the spring rod two 2102, and then the telescopic rod 2103 is pushed upward. The upper end of the telescopic rod 2103 is in contact with the inclined plate 5021 below the sliding plate 502. As the telescopic rod 2103 rises, to avoid uneven stress and make the sliding plate 502 unable to move and open, the sliding plate 502 is embedded with movable balls below to improve the stability of movement. The inclined plate 5021 is forced to drive the sliding plate 502 to move to the inside of the solder bin 501. Through the bending of the winding wire 18, the sliding distance of the sliding plate 502 is adjusted to change the opening size of the sliding plate 502 and the solder bin 501, so that a corresponding amount of solder slides. At this time, the solder in the solder bin 501 slides along the inclined plate 504 to the guide plate 505. Since the guide plate 505 is inclinedly arranged, and the winding wire 18 is movably embedded in the middle below the guide plate 505, the winding wire 18 is embedded in the middle below the guide plate 505 to prevent the solder from falling out, and then the solder is guided to the welding point between the winding wire 18 and the main wire 17. When the winding wire 18 is less bent, the pushing force of the fitting rotating wheel 2101 is reduced. At this time, the spring force of the spring rod one 503 drives the sliding plate 502 to reset, so as to reduce the opening size of the solder passage, and then adjust the solder flow according to the bending degree of the winding wire 18. When the main wire 17 rotates to the position below the guide plate 505 and contacts the winding wire 18, the current is connected through the current collector 22 and the current head 2201 to form a current loop. The contact point between the winding wire 18 and the main wire 17 is melted under the action of resistance, and the solder at the contact point between the main wire 17 and the winding wire 18 is melted at high temperature to form a covering welding point nodule, thereby improving the welding quality. By preheating and eliminating the stress of the winding wire 18, and by melting and cooling the solder to form a welding point nodule between the winding wire 18 and the main wire 17, the problems of damaging the structure of the main wire 17 by directly welding the winding wire 18 on the main wire 17 at a short distance, or reducing the welding strength due to the reduction of the fusion nucleus bonding area of the welding point between the winding wire 18 and the main wire 17 are avoided.

[0041] When the main reinforcement 17 rotates and is in contact with the winding reinforcement 18, the main reinforcement 17 is in contact with the lower vibration guide plate 24, at this time, the vibration guide plate 24 transmits the vibration generated by the vibrator 23 to the main reinforcement 17, and the vibration refines and diffuses the molten metal grains, and makes the molten metal more evenly fill the gap at the contact point, and at the same time, the molten solder further fills and covers the welding point, so as to further strengthen the firmness of the welding point. When the welding is completed, the main reinforcement 17 rotates and is out of contact with the power head 2201, and the vibration guide plate 24 is bent under stress and remains in contact with the main reinforcement 17 until it falls off. In the process of remaining in contact, the vibration transmission of the vibration guide plate 24 causes the welding residue at the welding point to further fall off under the action of vibration, so as to reduce the absorption of moisture and oxygen in the air by the residual welding material or welding residue due to the rough surface, thereby reducing the oxidation corrosion degree of the welding point.

[0046] As an embodiment of the present application, as shown in the figure, Figures 1 to 5 The inner side of the main reinforcement frame 6 and the movable main reinforcement frame 7 is embedded with the main reinforcement rotating disc 15, the outer side of the main reinforcement rotating disc 15 is fixedly installed with the hub 1503, which is limitedly installed in the main reinforcement frame 6 and the movable main reinforcement frame 7, one side of the main reinforcement rotating disc 15 is fixedly installed with the air pump 1501, the inner side of the main reinforcement rotating disc 15 is embeddedly installed with the multi-stage air pushing telescopic rod 1504, the outer side end of the multi-stage air pushing telescopic rod 1504 is fixedly installed with the clamping piece 1502, the output drive shaft on the differential mechanism 14 is arranged through the inside of one side of the movable main reinforcement frame 7, the hub 1503 is in transmission connection with the output drive shaft on the differential mechanism 14, the inner side of the clamping piece 1502 is embeddedly installed with the main reinforcement disc 16, and the main reinforcement disc 16 is fixedly installed with the main reinforcement clamp 1601 for clamping the main reinforcement 17.

[0047] In work, the air pump 1501 provides power for the multi-stage air pushing telescopic rod 1504, the multi-stage air pushing telescopic rod 1504 pushes the clamping piece 1502 to extend and retract, so that the main reinforcement disc 16 is quickly clamped and disassembled, the main reinforcement disc 16 fixes the main reinforcement 17 through the main reinforcement clamp 1601, so that the multiple main reinforcements 17 are distributed equidistantly along the circumference, when the main reinforcement rotating disc 15 rotates, the clamping piece 1502 firmly fixes the main reinforcement disc 16, so that the main reinforcement disc 16 is prevented from deviating during rotation operation.

[0048] Working principle: the cage winding flat car 1 is used as a bearing base, the cage winding frame 2 above the cage winding flat car 1 is used for installing the winding reinforcement disc 3, the winding reinforcement 18 wound on the winding reinforcement disc 3 can be put out on the cage winding frame 2 while rotating, the support frame 4 is fixedly installed on the cage winding flat car 1, the top of the support frame 4 is connected with the welded box 5, so that the welded box 5 is provided with stable support, so that the welded box 5 is kept horizontal and fixed in position during the conveying, heating and welding of the winding reinforcement 18, the cage winding flat car 1 is provided with universal wheels with brakes at four corners, so that the cage winding flat car 1 can be flexibly moved according to the requirements of the construction site, and the two slide rails 9 are limited through the fixed beam 11, and the winding frame 13 driven by the servo motor 12 is installed and used.

[0049] When the servo motor one 12 drives the winding frame 13 to rotate, the winding frame 13 pulls the sliding table 8 along the slide rail 9 through the pull rope 10, and the pull rod 801 ensures that the sliding tables 8 on the two slide rails 9 move synchronously, and then drives the movable main reinforcement frame 7 to move close to or away from the main reinforcement frame 6, so as to complete the position adjustment of the reinforcement cage in the length direction. When it is needed to pull the movable main reinforcement frame 7 back to the position close to the main reinforcement frame 6, the servo motor one 12 below the main reinforcement frame 6 drives the winding frame 13 to rotate, and the same transmission logic can be used to realize this action;

[0050] The servo motor two 1401 drives the hub 1503 to rotate through the differential mechanism 14, the hub 1503 drives the main reinforcement rotating disc 15 to rotate synchronously, and the main reinforcement 17 clamped on the main reinforcement rotating disc 15 rotates synchronously, thereby providing stable rotating power for the spiral winding of the winding reinforcement 18;

[0051] The air pump 1501 provides power for the multi-stage air push telescopic rod 1504, the multi-stage air push telescopic rod 1504 drives the clamping piece 1502 to extend and retract, thereby realizing quick clamping and dismounting of the main reinforcement disc 16. The main reinforcement disc 16 fixes the main reinforcement 17 through the main reinforcement clamp 1601 on the main reinforcement disc 16, so as to ensure that the plurality of main reinforcements 17 are distributed equidistantly in the circumferential direction. During the rotation of the main reinforcement rotating disc 15, the clamping piece 1502 can firmly fix the main reinforcement disc 16, so as to avoid deviation of the main reinforcement disc 16 during rotation;

[0052] The winding reinforcement 18 passes through the auxiliary feeding mechanism 21, the introduction mechanism 20 and the lead-out mechanism 25 in sequence under the rotating conveying force of the main reinforcement 17, is positioned and introduced into the welding box 5 through the introduction mechanism 20, then enters the high-frequency heater 19 for heat treatment, so as to eliminate internal stress and preheat, and facilitate subsequent resistance hot melting butt welding and shaping of the winding cage. Then, the winding reinforcement 18 passes through the auxiliary feeding mechanism 21 and is output from the welding box 5 through the lead-out mechanism 25, and then is bent and matched with the main reinforcement 17. In addition, the horizontal lead-out roller 2501 and the vertical lead-out roller 2502 embedded and movably arranged by the introduction mechanism 20 and the lead-out mechanism 25 are used to facilitate smooth conveying and output of the winding reinforcement 18 in the introduction mechanism 20 and the lead-out mechanism 25 in the welding box 5;

[0053] When there is a local bending around the tendon 18, the bending point pushes the one side of the rotating wheel 2101 to fit, so that the spring rod two 2102 is compressed. At this time, the pressure on the fitting rotating wheel 2101 is transmitted to the hydraulic oil through the spring rod two 2102, and then the telescopic rod 2103 is pushed to extend upward. The upper end of the telescopic rod 2103 is in contact with the inclined plate 5021 below the sliding plate 502. As the telescopic rod 2103 rises, to avoid uneven stress causing the sliding plate 502 to be unable to move to open, the rolling ball embedded movably below the sliding plate 502 is embedded to improve the stability of movement. The inclined plate 5021 is stressed to drive the sliding plate 502 to move to the inside of the solder bin 501. The sliding distance of the sliding plate 502 is adjusted by the bending of the tendon 18, so as to change the opening size of the sliding plate 502 and the solder bin 501, so that a corresponding amount of solder slides off.

[0054] At this time, the solder in the solder bin 501 slides along the inclined plate 504 to the guide plate 505. Since the guide plate 505 is inclinedly arranged, and the tendon 18 is movably embedded in the middle below the guide plate 505, the tendon 18 is embedded in the middle below the guide plate 505 to prevent the solder from falling out, and then the solder is guided to the welding point between the tendon 18 and the main tendon 17. When the bending degree of the tendon 18 is small, the pushing force on the fitting rotating wheel 2101 is reduced. At this time, the elastic force of the spring rod one 503 drives the sliding plate 502 to reset, so as to reduce the opening size of the solder passage, and then the solder flow is adjusted according to the bending degree of the tendon 18.

[0055] When the main tendon 17 rotates to the contact point below the guide plate 505 and the tendon 18, the current is connected through the current collector 22 and the current head 2201 to form a current loop. The contact point between the tendon 18 and the main tendon 17 is melted under the action of resistance, and the solder at the contact point between the main tendon 17 and the tendon 18 is melted at high temperature, forming a covering welding point nodule, so as to improve the welding quality.

[0056] When the main tendon 17 rotates and closely contacts with the tendon 18, the main tendon 17 is in contact with the vibration guide plate 24 below. At this time, the vibration guide plate 24 transmits the vibration generated by the vibrator 23 to the main tendon 17. Through the vibration, the molten metal grains are refined and diffuse migration, so that the molten metal fills the gap between the two contact points more uniformly. At the same time, the molten solder further fills and covers the welding point, so as to enhance the firmness of the welding point. After welding is completed, the main tendon 17 is separated from the current head 2201, and the vibration guide plate 24 remains in contact with the main tendon 17 in the state of being stressed and bent until it falls off. In the process of fitting, the vibration guide plate 24 continuously transmits vibration, so that the solder and slag at the welding point are further fallen off under the action of vibration, reducing the absorption of moisture and oxygen in the air by the residual solder or slag after welding due to the rough surface, so as to reduce the degree of oxidation corrosion of the welding point.

[0057] It should be noted that the vibrator 23 is mainly used to generate vibration here, and its model can be a Gt8 vibrator used by matching air supply, which is a prior art and will not be described in detail here; the high-frequency heater 19 is mainly used to heat and preheat the winding wire 18 and eliminate stress here, and its model can be a high-frequency heater on an LKH-120AB, which is a prior art and will not be described in detail here.

[0058] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
