Description

Technical Field

[0001] The present invention relates to the technical field of reinforcement installation auxiliary devices, and in particular to a reinforcement installation auxiliary device and method for a crash barrier capable of automatically positioning a mark. Background Art

[0002] The frame reinforcement of the anti-collision guardrail refers to the steel frame used for the anti-collision guardrail. It is a three-dimensional structure formed by combining steel bars. The function of the steel frame is to restrain the concrete and improve the integrity of the concrete components, thereby enhancing the stability and bearing capacity of the structure. In addition, the binding of the steel frame helps to form a steel grid, which is beneficial to improve the mechanical properties of the concrete components, ensure that the stressed steel bars can be fixed in the correct position, and connected into a steel frame to give full play to their respective mechanical properties.

[0003] Due to the transverse and longitudinal slopes of the bridge deck, it is necessary to control the position of the horizontal reinforcement of the guardrail to ensure that the guardrail line is straight. If manual measurement is used to adjust the position of the guardrail skeleton reinforcement, the construction efficiency is low and the accuracy is difficult to guarantee. Summary of the invention

[0004] The object of the present invention is to provide a device and method for installing a crash barrier reinforcement bar which can automatically locate and mark the guardrail reinforcement bar, so as to solve the problems raised in the prior art.

[0006] The cross bar 1 is provided with two groups of upper and lower loading tubes, each group of the loading tubes has two loading tubes, and a contact plate and a heat-conducting medium are installed in the loading tubes. The cross bar 2 is suspended with a positioning hammer through a pull rope, and the cross bar 2 and the pull rope are detachably connected. The staff can flexibly use different pull ropes according to the different heights of the guardrail frame. A detection tube is provided on the bottom plate below the positioning hammer, and a coil and a metal plate are installed in the detection tube.

[0007] The upper and lower groups of the carrier tubes are provided with sliding grooves on opposite sides. The carrier tube is hollow inside. A heat-conducting medium is arranged inside the carrier tube. A heating wire is arranged on the inner wall of the carrier tube. A temperature sensor is installed inside the carrier tube. The temperature sensor is used to monitor the temperature of the heat-conducting medium. The temperature sensor and the heating wire are electrically connected to the control system. The contact plate slides in the sliding groove. The contact plate is pressed against the carrier tube by a spring. The outer side of the contact plate is adapted to the surface of the guardrail frame. The inner side of the contact plate is in contact with the heat-conducting medium. The heat-conducting medium is made of a material that expands when heated.

[0008] A coil is arranged in the detection cylinder, and a metal plate is slidably contacted on the outer side of the coil. A magnet and an insulating plate are arranged on the upper side of the metal plate in sequence, and the insulating plate separates the magnet and the metal plate. A guide shaft passes through the metal plate, and a spring is connected between the metal plate and the detection cylinder. The guide shaft is installed on the detection cylinder. The magnet and the magnetic plate have the same magnetic pole on the opposite side, and the coil and the metal plate are electrically connected to the control system.

[0009] A plurality of positive plates are arranged on the upper side of the positioning hammer, and a magnetic plate is arranged on the lower side of the positioning hammer.

[0010] Press the start button on the control panel to start the device. The base plate is aligned with the ink line on the ground through the cooperation of the walking mechanism and the visual camera. The visual camera detects and identifies the position of the ink line, which is drawn on the ground in advance by the staff. The visual camera feeds back the position data to the control system. The control system adjusts the operation of the walking mechanism according to the ink line position data. After the walking mechanism drives one side of the base plate to align with the ink line on the ground, the control system cooperates with the lifting mechanism and the connecting rod to adjust the height of the fixed plate, cross bar one, cross bar two and the loading tube to adapt to different guardrail frame heights. The staff connects the pull rope to cross bar two to make the positioning hammer in a vertical state and located in the detection tube.

[0011] After the bottom plate is aligned with the ink line on the ground, the staff connects one end of the coil and the metal plate to the circuit and the positive plate and negative plate to the positive and negative poles of the power supply respectively through the control system;

[0012] When the positioning hammer entering the detection tube is in a vertical state, the positive plate on the positioning hammer and the negative plate on the inner wall of the detection tube are not in contact, and the metal plate is in the middle position of the coil. At this time, the current flowing through the coil and the metal plate is equal to the set current. At this time, the rotating rod does not need to be adjusted, the rotating rod is in a vertical state, and the set current is when the positioning hammer is in a vertical state, and then the control system cuts off the power to the coil and the metal plate.

[0013] When the positioning hammer in the detection tube is not in a vertical state, the positive plate on one side of the positioning hammer contacts the negative plate on the inner wall of the detection tube, and the other positive plates and negative plates do not contact. After the positive plates and negative plates contact, current will flow through. If the positioning hammer deflects to the left, current will flow through the corresponding positive plates and negative plates on the left. Since the detection tube and the positioning hammer are both provided with a plurality of positive plates and negative plates, the control system detects the current in the connection circuit between the plurality of positive plates and negative plates, and then obtains the deflection direction of the positioning hammer. Since the positioning hammer deflects along with the rotating rod and the second crossbar, the control system can obtain the deflection direction of the rotating rod.

[0014] When the positioning hammer is in the detection tube, the greater the deflection angle of the rotating rod, the deeper the pull rope and the positioning hammer enter the detection tube, the magnetic plate and the magnet on the positioning hammer repel each other, and under the action of the repulsive force, the magnet drives the metal plate to move downward. The staff connects the coil and the metal plate to the circuit through the control system. The current enters from one end of the coil, flows through the effective turns of the coil, and then flows out from the metal plate to the control system. The control system detects the current and obtains the position of the metal plate on the coil through calculation. The control system calculates the depth of the positioning hammer in the detection tube through the position of the metal plate, and then obtains the deflection angle of the rotating rod.

[0015] When the control system obtains the deflection direction and deflection angle of the rotating rod, the direction data and the angle data are fed back to the control system. The control system adjusts the rotation direction and the number of rotations of the driving motor according to the direction data and the angle data. The driving motor drives the threaded rod to rotate, and the threaded rod drives the sleeve to move. The sleeve pulls the rotating rod to rotate a certain angle, so that the rotating rod is in a vertical state. When no current flows through several positive plates and negative plates, it indicates that the positioning hammer is in a vertical state and the driving motor no longer rotates.

[0016] The staff places the guardrail frame on the contact plate between the two groups of loading tubes. The staff connects the heating wire on the inner wall of the loading tube to the circuit through the control system, so that the heating wire heats the heat-conducting medium. The heat-conducting medium expands after absorbing heat. After the heat-conducting medium expands, it pushes the contact plate to move and stretches the spring. The upper and lower groups of contact plates position and clamp the guardrail frame.

[0017] A plurality of negative plates are arranged on the inner wall of the detection cylinder, a plurality of positive plates and a plurality of negative plates are arranged opposite to each other, and a plurality of positive plates and negative plates are respectively connected to the positive electrode and the negative electrode of the power supply through wires.

[0018] The lifting mechanism comprises lifting rods, and the lifting rods are provided with four groups. The lifting rods are composed of upper vertical rods and lower vertical rods, and the upper vertical rods and the lower vertical rods are connected in a sliding seal. The lower vertical rods are installed on the bottom plate by bolts, and the bolts lock the lower vertical rods on the bottom plate. The lower vertical rods are located outside the upper vertical rods, and the lower vertical rods and the upper vertical rods are connected by springs. A support rod is connected between two adjacent groups of upper vertical rods, and the fixing plate is installed on the support rod;

[0019] The lower vertical rod and the connecting rod are both provided with air inlet holes, displacement sensors are installed on the lower vertical rod and the connecting rod, the air inlet holes are connected to the vacuum pump through pipelines, solenoid valves are installed in the air inlet holes, and the vacuum pump is installed on the bottom plate.

[0020] In order to adapt to the height of different guardrail frames, the device realizes height adjustment through the lifting mechanism and the connecting rod. The control system opens the solenoid valve in the air inlet of the connecting rod, and the vacuum pump pressurizes the external air and transmits it to the air inlet of the connecting rod through the pipeline. After the pressurized air enters the connecting rod, the pressure in the chamber between the connecting rod and the rotating rod increases, and the pressurized air pushes the rotating rod to move outward from the inside of the connecting rod and stretches the spring. The rotating rod drives the cross bar 1 and the cross bar 2 to move upward. After the cross bar 1 drives the two sets of carrier tubes to move to the set height, the displacement sensor on the connecting rod feeds back the data to the control system, and the control system controls the solenoid valve in the air inlet on the connecting rod to close, so that the chamber between the connecting rod and the rotating rod is in a closed state.

[0021] While air is being taken in through the air inlet hole on the connecting rod, the solenoid valve in the air inlet hole on the lower vertical rod opens, and the vacuum pump conveys pressurized air to the lower vertical rod through the pipe. The pressurized air enters the chamber between the upper vertical rod and the lower vertical rod, and the pressurized air pushes the upper vertical rod to move outward from the inside of the lower vertical rod and stretches the spring. The upper vertical rod drives the support rod to move upward, and the support rod drives the fixed plate to move upward, and the fixed plate drives the drive motor to move upward. The fixed plate, cross bar one, cross bar two and the loading tube are moved upward synchronously through the lifting mechanism and the connecting rod to adapt to different guardrail frame heights.

[0022] The walking mechanism includes a steering motor, a rotating gear and a roller. The rotating gear is installed around the base plate. A bracket is provided on the lower side of the rotating gear. The roller is installed on the bracket. A transmission belt is meshed on the outer side of the rotating gear. The middle part of one of the rotating gears is installed on the output shaft of the steering motor. The steering motor is installed on the base plate. The output shaft of the steering motor passes through the base plate. The remaining rotating gears are rotatably installed on the base plate through bearings. The interior of the roller is an electric roller structure.

[0023] The control system adjusts the direction of the roller by adjusting the steering motor. The steering motor drives the rotating gear to rotate a certain angle. The rotating gear drives the other rotating gears to rotate a certain angle through the transmission belt. The four sets of rotating gears synchronously drive the bracket to rotate a certain angle. The bracket drives the roller to rotate a certain angle to achieve the direction adjustment of the roller. The roller drives the bottom plate to move through the bracket.

[0024] The steering motor and the driving motor are both equipped with built-in encoders. The visual camera is located on a side close to the rotating rod, and the visual camera is electrically connected to the control system.

[0025] A control panel is installed on the bottom plate, and a control system is arranged inside the control panel.

[0032] 1. The guardrail frame can be placed quickly to improve construction efficiency. The position of the rotating rod is detected by the positioning hammer, and then the rotating rod is adjusted to a vertical position by the driving motor. The guardrail frame is then placed on the carrier tube of the rotating rod and positioned by the contact plate on the carrier tube to prevent deflection caused by external contact. After that, the next working position is moved by the walking mechanism. The staff can quickly place the guardrail frame to improve construction efficiency.

[0033] 2. It can adapt to guardrails of different heights to meet different usage requirements. The solenoid valve in the air inlet on the lower vertical rod is opened, and the vacuum pump delivers pressurized air to the lower vertical rod through the pipeline. The pressurized air enters the chamber between the upper and lower vertical rods, and the pressurized air pushes the upper vertical rod to move outward from the inside of the lower vertical rod and stretches the spring. The upper vertical rod drives the support rod to move upward, the support rod drives the fixed plate to move upward, and the fixed plate drives the drive motor to move upward; the lifting mechanism and the connecting rod are used to realize the synchronous upward movement of the fixed plate, crossbar 1, crossbar 2 and the carrier tube to adapt to different guardrail frame heights.

[0034] 3. Clamp and position the guardrail frame after positioning to prevent the guardrail frame from being deflected by external impact.

[0052] A method for installing a crash barrier reinforcement that can automatically locate a mark, using an auxiliary device for installing a crash barrier reinforcement that can automatically locate a mark, and including the following installation method:

[0053] S1, through the cooperation of the walking mechanism and the visual camera, the bottom plate is moved to a position flush with the ink line;

[0054] S2, adjusting the rotating rod 23 to a vertical position by driving the motor 2;

[0055] S3, placing the guardrail frame on the contact plate 261 between the two groups of carrier tubes 26;

[0056] S4. The contact plate 261 positions the guardrail frame.

[0057] Working principle: Press the start button on the control panel 1 to start the device. Through the cooperation of the walking mechanism and the visual camera, one side of the base plate 11 is aligned with the ink line on the ground. The visual camera detects and identifies the position of the ink line. The ink line is drawn on the ground in advance by the staff. The visual camera feeds back the position data to the control system. The control system adjusts the operation of the walking mechanism according to the data of the ink line position. After the walking mechanism drives one side of the base plate 11 to align with the ink line on the ground, the control system cooperates with the lifting mechanism and the connecting rod 28 to achieve height adjustment of the fixed plate 12, cross bar one 24, cross bar two 25 and the loading tube 26 to adapt to different heights of the guardrail frame 13. The staff connects the pull rope 251 to the cross bar two 25 to make the positioning hammer 27 in a vertical state and located in the detection tube 3.

[0058] After the bottom plate 11 is aligned with the ink line on the ground, the staff connects one end of the coil 31 and the metal plate 32 to the circuit and the positive plate 272 and the negative plate 301 to the positive and negative poles of the power supply respectively through the control system;

[0059] When the positioning hammer 27 entering the detection tube 3 is in a vertical state, the positive plate 272 on the positioning hammer 27 and the negative plate 301 on the inner wall of the detection tube 3 are not in contact, and the metal plate 32 is in the middle of the coil 31. At this time, the current flowing through the coil 31 and the metal plate 32 is equal to the set current. At this time, the rotating rod 23 does not need to be adjusted. The rotating rod 23 is in a vertical state. The set current is the current flowing through the coil 31 and the metal plate 32 when the positioning hammer 27 is in a vertical state.

[0060] When the positioning hammer 27 in the detection tube 3 is not in a vertical state, the positive plate 272 on one side of the positioning hammer 27 contacts the negative plate 301 on the inner wall of the detection tube 3, and the other positive plates 272 and negative plates 301 do not contact. After the positive plate 272 and the negative plate 301 contact, current will flow through. If the positioning hammer 27 deviates to the left, current will flow through the positive plate 272 and the negative plate 301 corresponding to the left side. Since the detection tube 3 and the positioning hammer 27 are both provided with a plurality of positive plates 272 and negative plates 301, the control system detects the current in the connection circuit between the plurality of positive plates 272 and the negative plates 301, and then obtains the deflection direction of the positioning hammer 27. The positioning hammer 27 deflects with the rotating rod 23 and the cross bar 25, so the control system can obtain the deflection direction of the rotating rod 23. After the control system obtains the deflection direction of the rotating rod 23, the control system cuts off the power to the coil 31 and the metal plate 32.

[0061] When the positioning hammer 27 is located in the detection tube 3, the greater the deflection angle of the rotating rod 23, the deeper the pull rope 251 and the positioning hammer 27 enter the detection tube 3, and the magnetic plate 271 and the magnet 33 on the positioning hammer 27 repel each other. Under the action of the repulsive force, the magnet 33 drives the metal plate 32 to move downward. The staff connects the coil 31 and the metal plate 32 to the circuit through the control system. The current enters from one end of the coil 31, flows through the effective turns of the coil 31, and then flows out from the metal plate 32 to the control system. The control system detects the current and obtains the position of the metal plate 32 on the coil 31 through calculation. The control system calculates the depth of the positioning hammer 27 in the detection tube 3 through the position of the metal plate 32, and then obtains the deflection angle of the rotating rod 23. The effective turns refer to the number of turns from the metal plate 32 to one end of the coil 31.

[0062] When the control system obtains the deflection direction and deflection angle of the rotating rod 23, the direction data and the angle data are fed back to the control system. The control system adjusts the rotation direction and the number of rotations of the driving motor 2 according to the direction data and the angle data. The driving motor 2 drives the threaded rod 21 to rotate, and the threaded rod 21 drives the sleeve 22 to move. The sleeve 22 pulls the rotating rod 23 to rotate a certain angle along the rotation position between the lower end of the connecting rod 28 and the bottom plate 11. The rotation angle is opposite to the inclination angle of the rotating rod 23, so that the rotating rod 23 is in a vertical state. When no current flows through several positive plates 272 and negative plates 301, it indicates that the positioning hammer 27 is in a vertical state and the driving motor 2 no longer rotates.

[0063] The staff places the guardrail frame 13 on the contact plate 261 between the two groups of carrier tubes 26, and connects the heating wire on the inner wall of the carrier tube 26 to the circuit through the control system, so that the heating wire heats the heat-conducting medium 262. The heat-conducting medium 262 expands after absorbing heat. After the heat-conducting medium 262 expands, it pushes the contact plate 261 to move and stretch the spring. The upper and lower groups of contact plates 261 position and clamp the guardrail frame 13.
