Description

Technical Field

[0001] This invention belongs to the field of positioning and measuring equipment technology, specifically a rapid positioning and measuring device for steel pipe piles of temporary steel trestle bridges. Background Technology

[0002] Steel trestle bridges, as temporary bridge structures, are widely used in water conservancy projects, bridge construction, and temporary construction sites to provide stable working platforms and passageways. During the construction of steel trestle bridges, the precise installation of steel pipe piles is a crucial step, as their positioning accuracy directly affects the overall structure's load-bearing capacity and durability.

[0003] During the installation of steel pipe piles, verticality is one of the key factors determining their performance. Excessive deviation can lead to a decrease in the bearing capacity of the steel pipe piles, damage to structural stability, and even the risk of tilting of the entire trestle bridge. As steel trestle bridges are spanning structures, they are usually built in complex terrain environments such as rivers and seas. Due to the impact of water flow and the complex topography of the water area, it is not convenient to monitor the verticality of the steel pipe piles in real time during installation, making the installation of steel pipe piles quite difficult. In order to solve this problem, a smart auxiliary positioning system for steel pipe piles on hard rock and bare rock in complex water areas has been disclosed. In this solution, an auxiliary positioning system consisting of multiple columns, multiple beams, light source verticality sensors, and displays is used to quickly form a vertical guide frame through light source illumination and other methods, providing guidance for the steel pipe piles and facilitating their rapid positioning.

[0004] However, in practical application, the following drawbacks were found in this solution:

[0005] 1. Since the measurement of the light source verticality sensor depends on the water inside the housing, in practical applications, it is necessary to ensure that the water surface is relatively close to the light emitted by the laser level. This is so that when the light source verticality sensor is tilted, the water can quickly submerge the corresponding laser level. Therefore, in practical applications, the accuracy of the water level height inside the light source verticality sensor is required to be high. In practical applications, the water inside the housing is affected by evaporation, wall adhesion, etc., which will lead to poor water surface stability, thus having a significant impact on the detection accuracy of the light source verticality sensor.

[0006] 2. Due to the vibration during the driving of steel pipe piles by hammer, and the vibration caused by the impact of water flow on the underwater guide frame, the vibration is transmitted to the verticality sensor of the light source through structures such as sliding rods. This not only causes fluctuations in the water surface inside the sensor, but also poses a possibility of malfunction or even damage to its internal components, further increasing the difficulty of detection by the verticality sensor of the light source.

[0007] In view of this, the present invention proposes a rapid positioning and measuring device for steel pipe piles of temporary steel trestle bridges to solve the above-mentioned technical problems. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes a rapid positioning and measuring device for steel pipe piles of temporary steel trestle bridges.

[0010] The guide is used to provide horizontal support for the measuring component. The guide consists of a fixed frame and support rods. The fixed frame is symmetrically fixed on both sides of the river channel. The support rods are divided into two groups, and the support rods on both sides are distributed parallel between the fixed frames.

[0011] The measuring element is mounted on the guide member and is used to detect the verticality of the steel pipe pile in real time. The measuring element includes:

[0012] A measuring frame and a socket frame are provided, both of which are mounted on a guide member. The measuring frame and the socket frame are parallel vertically, and the inner diameter of the socket frame is smaller than the inner diameter of the measuring frame.

[0013] A light source emitter and a receiver are provided. The light source emitter is fixedly mounted on the measuring frame, and the receiver is mounted on the socket frame. In the initial state, the light source emitter and the receiver are vertically aligned.

[0014] Preferably, a light-displaying strip is installed on the socket frame. In the initial state, the light source emitter, the light-displaying strip, and the receiver are vertically aligned. The light-displaying strip is used to display the light path emitted by the light source emitter.

[0015] Preferably, the top end of the light-emitting strip is hinged to the measuring frame, and the bottom end is hinged to the sleeve frame. The light-emitting strip is a telescopic rod-shaped structure. A traction rope is installed at the bottom of the light-emitting strip. The traction rope passes through the sleeve frame, and a weight is fixedly installed at the end of the traction rope away from the light-emitting strip.

[0016] Preferably, the socket frame includes a mounting frame, a driven rod, a support spring, a connector, and an electromagnetic plate;

[0017] The mounting frame is an annular frame, and the mounting frame has evenly distributed sliding grooves.

[0018] The driven rod corresponds one-to-one with the slide groove, the light source emitter, and the receiver. The driven rod is slidably mounted on the mounting frame through the slide groove, and a support spring is installed between the driven rod and the mounting frame.

[0019] The driven rod has a sliding groove at one end located outside the mounting frame. A connector is slidably installed in the sliding groove. The bottom end of the light-emitting strip is hinged to the connector. The receiver is embedded in the connector.

[0020] An electromagnetic plate is embedded in the driven rod and extends into the sliding groove. The electromagnetic plate is used to attract the connecting parts.

[0021] Preferably, the support spring is detachably fixedly installed on the driven rod, and in the initial state, the spacing of the plurality of driven rods matches the size of the steel pipe pile.

[0022] Preferably, the electromagnetic plate extends to the bottom of the driven rod, and the electromagnetic plate actively attracts the weight after being energized.

[0023] Preferably, both the measuring frame and the sleeve frame are provided with lifting grooves, and each lifting groove is elastically connected to a fixed plate by a lifting spring. The support rods extend into the lifting grooves respectively, and in the initial state, the fixed plate and the support rods are rubbed together under the pressure of the lifting spring.

[0024] Preferably, the light-emitting strip is formed by slidingly connecting an upper support rod and a lower sleeve. When the light-emitting strip is vertical, the lower sleeve is located on the descending path of the top fixed plate, and the bottom fixed plate is located on the lifting path of the driven rod.

[0026] Preferably, a tensioning wheel is rotatably mounted on the push rod, and a transmission belt is mounted on the traveling wheel, the pulley, and the tensioning wheel.

[0027] The beneficial effects of this invention are as follows:

[0028] The present invention discloses a rapid positioning and measuring device for steel pipe piles of temporary steel trestle bridges. By setting up guide components and measuring components, during the verticality monitoring of steel pipe piles, on the one hand, the guide components suspend the measuring components in mid-air above the river channel, thereby reducing the impact of water flow and the complex river environment on the measuring components. On the other hand, since the measuring frame and the connecting frame are only hinged together by the light-emitting strip of the telescopic structure, the measuring frame does not directly contact the steel pipe pile. During the pile driving process, the vibration generated by the pile driving has a smaller impact on the measuring frame. At the same time, in this invention, the combination of the light-emitting strip and the receiver not only increases the number of verticality judgment methods, but also utilizes the change in the optical path length caused by the tilt angle of the light-emitting strip to provide more intuitive and detailed data for verticality judgment, enhancing the convenience of steel pipe pile verticality measurement.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 7 As shown, the present invention provides a rapid positioning and measuring device for temporary steel trestle bridge steel pipe piles, comprising a guide component and a measuring component slidably mounted on the guide component;

[0040] The guide is used to provide horizontal support for the measuring component. The guide consists of a fixed frame 1 and support rods 11. The fixed frame 1 is symmetrically fixed on both sides of the river channel. The support rods 11 are divided into two groups, and the support rods 11 on both sides are distributed in parallel between the fixed frame 1.

[0041] The measuring element is mounted on the guide member and is used to detect the verticality of the steel pipe pile in real time. The measuring element includes:

[0042] Measuring frame 2 and socket frame, both of which are mounted on guide members, measuring frame 2 and socket frame are parallel vertically, and the inner diameter of socket frame is smaller than the inner diameter of measuring frame 2;

[0043] The light source emitter 21 and receiver 22 are fixedly mounted on the measuring frame 2, and the receiver 22 is mounted on the socket frame. In the initial state, the light source emitter 21 and receiver 22 are vertically aligned.

[0044] A light-displaying strip is installed on the socket frame. In the initial state, the light source emitter 21, the light-displaying strip, and the receiver 22 are vertically aligned. The light-displaying strip is used to display the light path emitted by the light source emitter 21.

[0045] The top end of the light-emitting strip is hinged to the measuring frame 2, and the bottom end is hinged to the sleeve frame. The light-emitting strip is a telescopic rod-shaped structure. A traction rope 23 is installed at the bottom of the light-emitting strip. The traction rope 23 passes through the sleeve frame, and a weight 24 is fixedly installed at the end of the traction rope 23 away from the light-emitting strip.

[0046] During the construction of a temporary steel trestle bridge, steel pipe piles need to be installed one by one along a designated route. In order to monitor the verticality of the steel pipe piles in a timely manner during installation so as to make timely adjustments after tilting occurs, this invention sets up a rapid positioning and measuring device consisting of guide components and measuring components. The positioning and measuring technology is used to realize the real-time measurement of the tilt of the steel pipe piles.

[0047] Specifically, during the preparation process before installing the steel pipe piles, the workers horizontally install the guide component on the riverbed. In this invention, the guide component consists of a fixed frame 1 and a support rod 11. The fixed frame 1 is fixedly installed on the riverbed by U-bolts, while the support rod 11 is located between the two fixed frames 1, providing a horizontal support platform for the measuring component. The measuring component is slidably installed on the support rod 11. In the initial state, the measuring component in this invention is above the area to be installed. At this time, the measuring frame 2 and the sleeve frame are connected by a light-emitting strip. Under the condition of no external force, the light-emitting strip is in a vertical state due to the gravity pull of the weight 24. The sleeve frame is vertically aligned with the measuring frame 2. At the same time, the light source emitter 21, the light-emitting strip, and the receiver 22 are on the same vertical path. The light emitted by the light source emitter 21 enters the light-emitting strip and shines on the receiver 22 through the light-emitting strip. It should be noted that in this invention, the light-emitting strip is made of a material used to display the light path. Its principle is that after the light shines into the interior of the light-emitting strip, it passes through the interior of the light-emitting strip. The scattering of fluorescent substances makes the light propagation path visible (this is conventional existing technology and will not be elaborated on here). Furthermore, when selecting components, the light emitted by the light source emitter 21 is a prominent red color, making it easy for workers to observe with the naked eye. During the installation of the steel pipe pile, the steel pipe pile is inserted downwards from the top of the measuring frame 2. Because the inner diameter of the sleeve frame is smaller than the inner diameter of the measuring frame 2, the sleeve frame eventually contacts the outer side of the steel pipe pile. During insertion and pile driving, when there is a deviation between the center of the steel pipe pile and the center of the sleeve frame, the sleeve frame and the measuring frame 2 are misaligned vertically under the push of the steel pipe pile. This causes the light-emitting strip to change from a vertical state to an inclined state. At this time, the light emitted by the always vertical light source emitter 21 not only cannot illuminate the receiver 22, but also, as the tilt angle of the light-emitting strip increases, the length of light illuminating within the light-emitting strip decreases, causing the light path length to shrink rapidly. This facilitates worker judgment, provides a reference for correcting the inclination of the steel pipe pile, and facilitates the vertical driving of the steel pipe pile.

[0048] This invention, by setting up guide components and measuring components, enables the verticality monitoring of steel pipe piles. On the one hand, the guide components suspend the measuring components in mid-air above the river channel, thereby reducing the impact of water flow and the complex river environment on the measuring components. On the other hand, since the measuring frame 2 and the connecting frame are only hinged together by the light-emitting strip of the telescopic structure, the measuring frame 2 does not directly contact the steel pipe pile. During the pile driving process, the vibration generated by the pile driving has a smaller impact on the measuring frame 2. At the same time, the combination of the light-emitting strip and the receiver 22 in this invention not only increases the number of verticality judgment methods, but also utilizes the change in the optical path length caused by the tilt angle of the light-emitting strip to provide more intuitive and detailed data for verticality judgment, enhancing the convenience of steel pipe pile verticality measurement.

[0049] The socket frame includes a mounting frame 25, a driven rod 27, a support spring 28, a connector 2a, and an electromagnetic plate 2b;

[0050] The mounting frame 25 is an annular frame, and the mounting frame 25 is provided with evenly distributed sliding grooves 26.

[0051] The driven rod 27 corresponds one-to-one with the slide groove 26, the light source emitter 21, and the receiver 22. The driven rod 27 is slidably mounted on the mounting frame 25 through the slide groove 26. A support spring 28 is installed between the driven rod 27 and the mounting frame 25.

[0052] The driven rod 27 has a sliding groove 29 at one end located outside the mounting frame 25. A connector 2a is slidably installed in the sliding groove 29. The bottom end of the light-emitting strip is hinged to the connector 2a. The receiver 22 is embedded in the connector 2a.

[0053] An electromagnetic plate 2b is embedded in the driven rod 27, and the electromagnetic plate 2b extends into the sliding groove 29. The electromagnetic plate 2b is used to attract the connector 2a.

[0054] The support spring 28 is detachably fixedly installed on the driven rod 27, and in the initial state, the spacing of the multiple driven rods 27 matches the size of the steel pipe pile.

[0055] The electromagnetic plate 2b extends to the bottom of the driven rod 27, and the electromagnetic plate 2b actively attracts the weight 24 after being energized.

[0056] To further improve the convenience of measuring the verticality of steel pipe piles, the sleeve frame in this invention consists of an installation frame 25, driven rods 27, support springs 28, connectors 2a, and an electromagnetic plate 2b. When installing steel pipe piles of different diameters, the workers actively change the support springs 28 according to the diameter of the steel pipe pile to be installed. Under the action of the support springs 28, the driven rods 27 slide in the sliding grooves 26, ultimately making the spacing of the multiple driven rods 27 match the size of the steel pipe pile. During this process, the electromagnetic plate 2b is de-energized. When the driven rods 27 move, the weight 24 pulls the traction rope 23, and the connector 2a slides in the sliding grooves 29 on the driven rods 27 under force, causing the light strip to... The connector 2a, traction rope 23, and counterweight 24 remain vertical. After the support spring 28 is replaced, the electromagnetic plate 2b is activated, and the electromagnetic plate 2b magnetically fixes the connector 2a and counterweight 24, thus fixing the connector 2a, driven rod 27, and counterweight 24. During the insertion and driving of the steel pipe pile, when the steel pipe pile tilts, the steel pipe pile will exert pressure on the driven rod 27 on the tilted side until the driven rod 27 pulls the connector 2a to move. The light strip, which is hinged to the connector 2a at its bottom, changes from vertical to tilted. The driven rod 27, which is not in the tilting direction of the steel pipe pile, is not affected, further facilitating the workers to correct the verticality of the steel pipe pile.

[0057] Both the measuring frame 2 and the sleeve frame are provided with lifting grooves 3. Each lifting groove 3 is elastically connected to a fixed plate 32 by a lifting spring 31. The support rod 11 extends into the lifting groove 3. In the initial state, the fixed plate 32 and the support rod 11 are rubbed together under the pressure of the lifting spring 31.

[0058] The light-emitting strip is formed by the upper support rod 4 and the lower sleeve 41 slidingly connected. When the light-emitting strip is vertical, the lower sleeve 41 is located on the descending path of the top fixed plate 32, and the bottom fixed plate 32 is located on the lifting path of the driven rod 27. A push rod 42 is slidably installed on the measuring frame 2. The push rod 42 is used to push the top fixed plate 32 down.

[0059] To reduce the impact of the inclined steel pipe pile on the driven rod 27 in the non-inclined direction, in this invention, both the measuring frame 2 and the mounting frame 25 are provided with lifting grooves 3, and fixing plates 32 are installed in the lifting grooves 3 by lifting springs 31. In the initial state, i.e., when the measuring component is above the installation position, the measuring frame 2 and the sleeve frame are vertically aligned. Under the action of the lifting springs 31, the fixing plates 32 are tightly attached to the support rod 11. Through friction, the measuring frame 2 and the mounting frame 25 are fixed to the support rod 11. Therefore, when the steel pipe pile is inclined, the steel pipe pile will only affect the directly driven rod 27. When changing the position of the measuring component after the steel pipe pile is installed, the fixed plate 32 inside the measuring frame 2 is directly pushed by the push rod 42. At the same time, since there are no foreign objects inside the measuring component, the light bars are all in a vertical state. As the fixed plate 32 inside the measuring frame 2 (that is, the top fixed plate 32) descends, it pushes the lower sleeve 41. The lower sleeve 41 squeezes the connector 2a. The connector 2a pushes the driven rod 27. The driven rod 27 pushes the bottom fixed plate 32 downward, thereby causing the measuring frame 2 and the fixed plate 32 inside the sleeve frame to separate from the support rod 11, so as to push the measuring component to slide on the guide and change the installation position of the steel pipe pile.

[0060] A drive motor 43 is fixedly installed on the measuring frame 2. A pulley 44 is fixedly installed on the output end of the drive motor 43. A traveling wheel 45 is rotatably installed on the measuring frame 2. The traveling wheel 45 extends into the lifting groove 3 and is frictionally connected to the support rod 11. A gear 46 is fixedly installed on the output end of the drive motor 43. One side of the push rod 42 has a rack-and-pinion design.

[0061] A tensioning wheel 47 is rotatably mounted on the push rod 42, and a transmission belt 48 is mounted on the walking wheel 45, the pulley 44 and the tensioning wheel 47.

[0062] To further enhance the ease of use of the device, in this invention, a drive motor 43 is installed on the measuring frame 2. When preparing to adjust the position of the measuring component on the guide, the drive motor 43 starts, driving the pulley 44 and gear 46 to rotate. Since the transmission belt 48 between the pulley 44 and the traveling wheel 45 is in a slack state at this time, the traveling wheel 45 does not move, while the gear 46 engages with the push rod 42 for transmission. Under the pushing action of the gear 46, the push rod 42 moves downward. After transmission, it causes the top and bottom fixing plates 32 to move downward. Separating from the support rod 11, the measuring component and the guide component change from a fixed state to a slidable connection state. Simultaneously, as the push rod 42 continues to descend, the tensioning wheel 47 moves downward, forming a triangular arrangement with the pulley 44 and the traveling wheel 45. This tightens the transmission belt 48 that is shared by all three. At this time, the drive motor 43 drives the traveling wheel 45 to rotate via the pulley 44 and the transmission belt 48. The traveling wheel 45, through friction with the support rod 11, causes the measuring component to move directionally on the support rod 11, thereby adjusting the position of the measuring component on the guide component.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
