Description

Technical Field

[0001] The present invention relates to the technical field of cast-in-place pile detection, and particularly to a bridge pier detection device. Background Art

[0002] A pier is a lower load-bearing structure used to support the upper structure in civil engineering. The cross-section of a pier is mostly circular, and there are also special-shaped piers such as oval, square, curved, and parabolic. It is an important component in projects such as highway bridges, railway bridges, sidewalks, overpasses, ramp bridges, and skybridges.

[0003] For example, for a bridge pier detection device with a Chinese patent application number of CN201910788504.7, when using multi-channel radar, photographic equipment, and infrared imaging for detection, it can only be detected by vertically suspended descent. In this way, a support point needs to be set at the upper end of the column, resulting in low erection and installation efficiency and being unable to be applied to the detection of piers with bridges already erected at the upper end. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose a bridge pier detection device.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A bridge pier detection device includes an arc-shaped guide rail frame. There is a guide chute on the upper side of the arc-shaped guide rail frame. An arc-shaped slider is slidably connected in the guide chute. An arc-shaped plate is fixedly connected to the upper side of the arc-shaped slider. Two detectors are respectively fixedly connected to both ends of the upper side of the arc-shaped plate. It also includes a support device and a driving device;

[0007] The support device includes a suspension plate. A turntable is fixedly connected to one side of the suspension plate.

A support rod is provided on each of the support rods hinged to both ends of the arc-shaped guide rail frame. A torsion spring is provided on the rotation axis of the support rod and the arc-shaped guide rail frame;

[0008] The driving device drives the arc-shaped slider to slide in the guide chute.

[0009] Preferably, the driving device includes a support plate. The support plate is fixedly connected to a driving motor. The main shaft of the driving motor is fixedly connected to a second walking wheel. The second walking wheel is in pressing contact with the outer side of the arc-shaped guide rail frame.

[0010] Preferably, the support rod includes a rod body with a square tube structure, the support rod is provided with a mounting groove, the rod body is rotatably connected in the mounting groove, one end of the rod body is an open structure and is slidably connected to the square rod, the end of the square rod is fixedly connected to two forked rods, the end of the forked rod is rotatably connected to the ball, the other end of the rod body is fixedly connected to a blind plate, the blind plate is threadedly connected to a screw, one end of the screw extending into the rod body is rotatably connected to a push block, the push block is slidably connected to the inner wall of the rod, and a support spring is fixedly connected between the push block and the square rod.

[0011] Preferably, a square socket is provided at one end of the support rod away from the arc-shaped guide rail frame, a hinged rod is inserted into each socket, and a cross bar is hinged between the two hinged rods. A round hole is provided on the upper side of the end of the support rod, and the round hole is connected to the square socket. A sliding hole is provided on the upper side of the hinged rod, and a vertical sliding plug rod is connected in the sliding hole. The plug rod is adapted to the round hole, and a first spring is fixedly connected between the plug rod and the bottom of the sliding hole.

[0012] Preferably, the cross bar includes two side bars, the hinged rod is hingedly connected to the end of the side bar, and the opposite ends of the two side bars are provided with sliding holes.

[0014] The advantages of the present invention are that: a bridge pier detection device provided by the present invention climbs through the first walking wheel, and cooperates with the rotation of the first motor to deflect the first walking wheel from a vertical state, and returns to the positive position and deflects in the opposite direction after traveling a certain distance, which correspondingly causes the arc guide frame to form a certain amplitude of rotation relative to the column during the climbing process, compensating for the defect that the arc guide frame can only be set into a semicircle and the extension range of the arc plate cannot cover the entire circumference of the column. In this way, the scanning path of the detector is not simply vertically upward, which facilitates sampling detection of the column from different angles, reduces omissions, and thus improves detection efficiency.

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] As Figure 1-7 shown, a bridge pier detection device provided by the present invention includes an arc guide rail frame 1. The arc guide rail frame 1 is a semi-circular structure. A guide chute 11 is provided on the upper side of the arc guide rail frame 1. An arc slider 12 is slidably connected in the guide chute 11. An arc plate 13 is fixedly connected to the upper side of the arc slider 12. Two detectors 14 are respectively fixedly connected to both ends of the upper side of the arc plate 13. The detector 14 is a multi-channel radar or a photographic device. The detector 14 is additionally equipped with a wireless communication device of the prior art, such as a Bluetooth module or a 5G module, to wirelessly transmit the detection data of the detector 14 to the terminal device in the hands of the detection personnel, so as to facilitate obtaining the detection results of different positions of the column body of the bridge pier. A plurality of vertical rods 15 are fixedly connected to the upper side of the arc plate 13. The heights of the plurality of vertical rods 15 gradually decrease in the direction away from the arc slider 12. A stay cable 16 is fixedly connected between the plurality of vertical rods 15. When one end of the arc plate 13 is far away from the arc guide rail frame 1, the stay cable 16 forms a stay support for the distal end to prevent the distal end of the arc plate 13 from sagging. It further includes a support device 2 and a driving device 3;

[0025] The driving device 3 drives the arc slider 12 to slide in the guide chute 11. The driving device 3 includes a support plate 31. The support plate 31 is fixedly connected to a driving motor 32. The main shaft of the driving motor 32 is fixedly connected to a second traveling wheel 33. The second traveling wheel 33 is in pressing contact with the outer side of the arc guide rail frame 1. <_{

[0026] }The supporting device 2 includes a hanging plate 21, one side of the hanging plate 21 is fixedly connected to the turntable 22, and the other side of the hanging plate 21 is fixedly connected to the first motor 23. The main shaft of the first motor 23 passes through the hanging plate 21 and is fixedly connected to the turntable 22. One side of the turntable 22 is fixedly connected to the second motor 25, and the main shaft of the second motor 25 is fixedly connected to the first walking wheel 26. A support rod 27 is hinged at each end of the arc guide frame 1. A torsion spring is provided on the support rod 27 and the rotating axis of the arc guide frame 1, and each support rod 27 is provided with a support rod 4;

[0027] The first running wheel 26 and the second running wheel 33 are both tires. The tires press against the contact surface and drive the contact surface to move when they rotate forward and backward.

[0028] The function of the support device 2 is to provide the first walking wheel 26 with a first support point and a climbing driving force. The torsion spring enables the support rod 27 to have a pressing force against the column. The support rod 4 of the two support rods 27 is supported on the column through the torsion spring pressure contact, and forms a three-point contact support with the support point of the first walking wheel 26 on the periphery of the column. When more support points are needed, the number of support rods 4 is increased on the support rod 27 to provide a more stable support. The frame body of this device is an aluminum alloy pipe structure with a light weight, which is convenient for climbing. The driving position is set in the middle of the arc-shaped guide rail frame 1 and the center of gravity of this device is set in the middle. The first walking wheel 26 serves as the main support point and the support rod 4 serves as the secondary support point. Therefore, actively driving the first walking wheel 26 to rise overcomes the gravity of this device.

[0029] The present invention climbs by means of the first traveling wheel 26, and cooperates with the rotation of the first motor 23 to make the first traveling wheel 26 deflect 10-15° from the vertical state, and return to the normal state and deflect 10-15° in the opposite direction after traveling a certain distance, which correspondingly makes the arc guide frame 1 rotate to a certain extent relative to the column during the climbing process, compensating for the defect that the arc guide frame 1 can only be set into a semicircle and the extension range of the arc plate 13 cannot cover the entire circumference of the column. In this way, the scanning path of the detector 14 is not simply vertically upward, which facilitates sampling detection of the column from different angles, thereby improving detection efficiency.

[0030] As a further improvement of the present invention, a square socket 5 is provided at one end of the support rod 27 away from the arc-shaped guide rail frame 1, and a hinged rod 51 is inserted into each socket 5. The two hinged rods 51 are hinged to the cross bar 6. A circular hole 52 is provided on the upper side of the end of the support rod 27, and the circular hole 52 is connected to the square socket 5. The upper side of the hinged rod 51 is provided with a sliding hole, and a plug rod 53 is vertically slidably connected in the sliding hole. The plug rod 53 is adapted to the circular hole 52, and a first spring is fixedly connected between the plug rod 53 and the bottom of the sliding hole.

[0031] In the present invention, a sleeve 611 is provided on the cross bar 6. A square rod 612 is slidably connected inside the sleeve 611. A compression spring is fixedly connected between the square rod 612 and the cross bar 6. The end of the square rod 612 is rotatably connected to a support wheel 613. The support wheel 613 presses against the outside of the column. After the first traveling wheel 26 of the arc-shaped guide rail frame 1 contacts the column, each support rod 27 is clamped and individually pulled by an existing tractor, so that the first traveling wheel 26 forms a pressing contact. At this time, the cross bar 6 is inserted and connected through the hinge rod 51 in the insertion hole 5 of the support rod 27. When the tractor is removed, the first traveling wheel 26 and the support wheel 613 are elastically pressed against both sides of the column, and with the support of the support rod 4, it plays a role in stably supporting the outside of the column. Thus, when the first traveling wheel 26 rotates, the present invention climbs on the outside of the column, and can avoid slipping of the first traveling wheel 26 during climbing.

[0032] After the detection is completed, the arc-shaped guide rail frame 1 is lowered to a low position. The staff uses a round rod to push the plug rod 53 into the insertion hole 5. The plug rod 53 is completely retracted into the sliding hole on the upper side of the hinge rod 51, and then the cross bar 6 can be conveniently pulled outwards.

[0033] By providing a detachable cross bar 6 at the outer ends of the two support rods 27, the arc-shaped guide rail frame 1, the two support rods 27 and the cross bar 6 form an enclosure, further improving the stability of the present invention. And by the different lengths of the cross bar 6, it can adapt to the detection of columns floating within a certain range, thus improving the versatility.

[0034] Furthermore, the support rod 4 includes a rod body 41 with a square tube structure. The support rod 27 is provided with an installation groove 42. The rod body 41 is rotatably connected in the installation groove 42. Rotating shafts are respectively fixedly connected to the top and bottom of the rod body 41. The rotating shafts are rotatably connected to the opposite inner walls of the installation groove 42. The rod body 41 swings left and right in the installation groove 42 to facilitate finding a suitable normal position. One end of the rod body 41 is of an open structure and is slidably connected to a square rod 43. The end of the square rod 43 is fixedly connected to two bifurcated rods 44. The ends of the bifurcated rods 44 are rotatably connected to rolling balls 45. The other end of the rod body 41 is fixedly connected to a blind plate 46. The blind plate 46 is threadedly connected to a screw rod 47. The end of the screw rod 47 extending into the rod body 41 is rotatably connected to a push block 48. The push block 48 is slidably connected to the inner wall of the rod body 41. A support spring 49 is fixedly connected between the push block 48 and the square rod 43. The screw rod 47 rotates to adjust the pre-tightening force of the support spring 49.

[0035] In the present invention, due to the structural differences of the columns, when the arc-shaped guide rail frame 1 deflects around the column, there will be a certain range of floating in the tangent angles between the support rods 27 and the column. As Figure 5 shown, the tangent angles between the two support rods 27 and the column are different. Therefore, the present invention is provided with two bifurcated rods 44, as Figure 7As shown, the support point of the support rod 4 is located in the middle, and the support points formed by the two bifurcated rods 44 are separated on both sides. The support spring 49 provides a pressing force. When the phase position of the support rod 27 changes, the rod body 41 can automatically align to the diameter direction of the cylinder, so that the auxiliary support point plays a role in stable support.

[0036] In view of the structural differences existing in the existing cylinders, for example Figure 4 As shown, there are single cylinders, double cylinders, and a cross beam is provided between the double cylinders. In view of this engineering condition, the cross beam forms an obstacle to the climbing detection. Therefore, the main structures of the two above-mentioned inventions are used to replace the structure of the cross bar 6. The specific replacement structure is as follows:

[0037] The cross bar 6 includes two side bars 61. The articulated rod 51 is articulated and connected to the end of the side bar 61. Sliding holes 62 are provided at one end of the two side bars 61 opposite to each other. An extension rod 63 is slidably connected in the sliding holes 62 of the two side bars 61 together. Hook springs are fixedly connected between the two ends of the extension rod 63 and the bottom of the opposite sliding holes 62.

[0038] When detecting the cylinder with a double-cylinder structure, during the deflection of the two arc guide frames 1, the internal telescopic compensation of the cross bar 6 can form a state as shown in Figure 6 so as to perform a surrounding climbing detection on the double-cylinder, taking into account the full detection while adapting to cylinders of various specifications, so that the adaptation range is wide and the detection time is saved.

[0039] The method of controlling the first motor 23, the second motor 25, and the drive motor 32 in the present invention belongs to the prior art. Only a simple logic control program needs to be written to realize the functions described above, which is an application of the common prior art in the aspect of automatic control. Due to limited space, the principle will not be elaborated here.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
