Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, specifically to a support wedge block height and tilt angle adjustment device. Background Technology

[0002] During the construction of precast beams, it is necessary to adjust the cross slope of the beam body using embedded steel plates or wedge blocks (the cross slope is often adjusted in the design by using cap beams or bearing pads, while the longitudinal slope is adjusted by embedding steel plates or using wedge blocks at the bottom of the beam). In the traditional construction process of precast beam bridges, the cross slope of the precast beam bridge is adjusted by adjusting the thickness of the wedge blocks embedded in the bottom of the beam on both sides. Especially for beams with a large cross slope (4%) or inconsistent cross slopes, it is necessary to adjust the thickness of the wedge blocks on both sides individually according to the precast beams at different locations.

[0003] In existing technologies, workers rely on measuring equipment to determine the installation angle of the wedge blocks on-site, which is inconvenient for construction.

[0004] In summary, there is an urgent need for a support wedge block height and tilt angle adjustment device to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a support wedge block height and tilt angle adjustment device, which aims to solve the problem that existing equipment requires on-site manual measurement to determine the installation angle of the wedge block, resulting in inconvenience in construction. The specific technical solution is as follows:

[0006] A support wedge block height and tilt angle adjustment device includes a base plate, a top plate, a first telescopic component, and a second telescopic component. The top plate is arranged above the base plate. The first end of the first telescopic component is fixedly connected to the base plate, and the second end of the first telescopic component is hinged to the top plate. The first end of the second telescopic component is fixedly connected to the base plate, and the second end of the second telescopic component slides and abuts against the top plate.

[0007] Furthermore, the first telescopic assembly includes two first telescopic rods, which are arranged side by side at one end of the base plate. The bottom ends of the first telescopic rods are fixedly connected to the base plate, and the top ends of the first telescopic rods are hinged to the top plate. The second telescopic assembly includes two second telescopic rods, which are arranged side by side at one end of the base plate away from the first telescopic assembly. The bottom ends of the second telescopic rods are fixedly connected to the base plate, and the top ends of the second telescopic rods slide and abut against the top plate.

[0008] Furthermore, the base plate is provided with four limiting holes, in which two first telescopic rods and two second telescopic rods are inserted and fixed. The first telescopic rod includes a first cylinder and a first piston rod. The first piston rod telescopically engages in the first cylinder, and the first cylinder is inserted and fixed in the corresponding limiting hole. The end of the first piston rod away from the first cylinder is arranged in a spherical shape. A hemispherical groove is provided on the bottom surface of the top plate, and the spherical end of the first piston rod is embedded in the hemispherical groove. The second telescopic rod includes a second cylinder, a second piston rod, and a slider. The second piston rod telescopically engages in the second cylinder, and the slider is hinged to the end of the second piston rod away from the second cylinder. The second cylinder is inserted and fixed in the corresponding limiting hole. A sliding groove is provided on the top plate, and the sliding groove is arranged in a direction away from the first telescopic rod. The slider slides in the sliding groove.

[0009] Furthermore, the second telescopic rod also includes a pad, which is fixedly connected to the top of the slider. The top of the pad abuts against the inner wall of the groove, and the pad is made of wear-resistant material.

[0010] Furthermore, the base plate is provided with four mounting holes arranged along the height direction, and the four mounting holes are respectively arranged corresponding to the two first telescopic rods and the two second telescopic rods.

[0011] Furthermore, it also includes a tilt sensor, which is detachably connected to the top plate;

[0012] The top plate is provided with a receiving groove, in which the tilt sensor is installed and completely embedded.

[0013] Furthermore, the top plate is provided with a first threaded hole and a second threaded hole. There are four first threaded holes, which are respectively arranged at the four corners of the top of the top plate. The second threaded hole is arranged on the side of the top plate. The bottom plate is provided with a third threaded hole, which is arranged on the side of the bottom plate.

[0014] Furthermore, the top plate is provided with a rotatable handle, and the bottom plate is provided with a slot. When the top plate is closed on the bottom plate, the handle rotates and engages in the slot. There are four handles, two of which are located on the first side of the top plate and the other two are located on the second side of the top plate.

[0015] Furthermore, a magnetic block is arranged inside the card slot, the handle is made of steel, and a finger groove is provided on the base plate, which is connected to the card slot.

[0016] Furthermore, a positioning pin is provided on the base plate, and a corresponding positioning hole is provided on the top plate.

[0017] The application of the technical solution of this utility model has the following beneficial effects:

[0018] When the overall height of the device needs to be adjusted individually, the first and second telescopic components extend or retract synchronously, causing the top plate to rise or fall, thereby changing the overall height of the device. When the angle of the device needs to be adjusted individually, the first telescopic component remains stationary, while the second telescopic component extends or retracts. This keeps the height of the side of the top plate closest to the first telescopic component constant, while raising or lowering the height of the side closest to the second telescopic component, thus adjusting the angle of the device. When both height and angle adjustments are required, the first and second telescopic components extend or retract simultaneously. Adjusting the extension or retraction distance of the first and second telescopic components allows for simultaneous adjustment of both height and angle. During adjustment, the first and second telescopic components are retracted simultaneously. The adjusting device is then placed under the bridge box girder and between the bridge pier, and the first and second telescopic components are extended until the top plate is flush with the bottom surface of the bridge box girder. This process can be completed without manual measurement and adjustment, making installation convenient and construction easy.

[0027] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] Example:

[0030] See Figures 1-5 This embodiment provides a support wedge block height and tilt angle adjustment device, including a base plate 1, a top plate 2, a first telescopic component 3 and a second telescopic component 4. The top plate 2 is arranged above the base plate 1. The first end of the first telescopic component 3 is fixedly connected to the base plate 1, and the second end of the first telescopic component 3 is hinged to the top plate 2. The first end of the second telescopic component 4 is fixedly connected to the base plate 1, and the second end of the second telescopic component 4 slides and abuts against the top plate 2.

[0031] It can be understood that when the overall height of the device needs to be adjusted individually, the first telescopic component 3 and the second telescopic component 4 are extended or retracted synchronously, causing the top plate 2 to rise or fall, thereby changing the overall height of the device. When the angle of the device needs to be adjusted individually, the first telescopic component 3 remains stationary, and the second telescopic component 4 is extended or retracted, so that the height of the side of the top plate 2 closest to the first telescopic component 3 remains unchanged, while the height of the side of the top plate 2 closest to the second telescopic component 4 rises or falls, thus achieving angle adjustment of the device. When both height and angle adjustment of the device are required, the first telescopic component 3 and the second telescopic component 4 are extended or retracted simultaneously, and the distance of extension or retraction of the first telescopic component 3 and the second telescopic component 4 is adjusted to achieve simultaneous adjustment of the height and angle of the device. During the adjustment process, the first expansion joint 3 and the second expansion joint 4 are retracted simultaneously. The adjustment device is then placed between the box girder of the bridge and the pier, allowing the first expansion joint 3 and the second expansion joint 4 to extend until the top plate 2 is in contact with the bottom surface of the bridge box girder. This process can be completed without manual measurement and adjustment, making it convenient for installation and construction.

[0032] Furthermore, the first telescopic assembly 3 includes two first telescopic rods 31, which are arranged side by side at one end of the base plate 1. The bottom ends of the first telescopic rods 31 are fixedly connected to the base plate 1, and the top ends of the first telescopic rods 31 are hinged to the top plate 2. The second telescopic assembly 4 includes two second telescopic rods 41, which are arranged side by side at one end of the base plate 1 away from the first telescopic assembly 3. The bottom ends of the second telescopic rods 41 are fixedly connected to the base plate 1, and the top ends of the second telescopic rods 41 slide and abut against the top plate 2.

[0033] Specifically, the two first telescopic rods 31 need to extend or retract simultaneously during operation, and the two second telescopic rods 41 also need to extend or retract simultaneously during operation. The top ends of the first telescopic rods 31 are hinged to the top plate 2, and the top ends of the second telescopic rods 41 slide and abut against the top plate 2. This arrangement allows the contact points between the second telescopic rods 41 and the top plate 2 to slide relative to each other during angle adjustment, enabling the top plate 2 to smoothly change angle and preventing jamming between the top plate 2 and the second telescopic rods 41.

[0034] It is understood that the height and angle of the top plate 2 are adjusted by extending or retracting the first telescopic rod 31 and the second telescopic rod 41. It should be noted that during angle adjustment, only the angle along the line connecting the first telescopic rod 31 and the second telescopic rod 41 can be adjusted; the angle perpendicular to the line connecting the first telescopic rod 31 and the second telescopic rod 41 cannot be adjusted.

[0035] Furthermore, the base plate 1 is provided with four limiting holes 11, and the two first telescopic rods 31 and the two second telescopic rods 41 are all inserted and fixed in the limiting holes 11 along the height direction; the first telescopic rod 31 includes a first cylinder 311 and a first piston rod 312, the first piston rod 312 is telescopically fitted in the first cylinder 311, the first cylinder 311 is inserted and fixed in the corresponding limiting hole 11, the end of the first piston rod 312 away from the first cylinder 311 is arranged in a spherical shape, and a hemispherical groove 21 is provided on the bottom surface of the top plate 2, the spherical end of the first piston rod 312 is embedded in the hemispherical groove. In section 21, a ball joint is formed. The top plate 2 is supported by the first piston rod 312. The second telescopic rod 41 includes a second cylinder 411, a second piston rod 412, and a slider 413. The second piston rod 412 is telescopically engaged in the second cylinder 411. The slider 413 is hinged to the end of the second piston rod 412 away from the second cylinder 411. The second cylinder 411 is inserted and fixedly engaged in the corresponding limiting hole 11. A sliding groove 22 is arranged on the top plate 2. The sliding groove 22 is arranged in a direction away from the first telescopic rod 31. The slider 413 is slidably engaged in the sliding groove 22.

[0036] Specifically, the four limiting holes 11 are respectively arranged at the four corners of the base plate 1, and the first cylinder 311 on the two first telescopic rods 31 are respectively inserted into the two limiting holes 11 at one end of the base plate 1, and the second cylinder 411 on the two second telescopic rods 41 are respectively inserted into the two limiting holes 11 at the other end of the base plate 1.

[0037] It can be seen that the first cylinder 311 is connected to the base plate 1 by a plug-in fit, and the first cylinder 311 is limited by the limiting hole 11 to prevent it from tilting under the action of external force; similarly, the limiting hole 11 also limits the second cylinder 411. It is worth noting that the plug-in fit connection facilitates installation and disassembly, speeds up construction, and helps save labor costs.

[0038] Furthermore, the second telescopic rod 41 also includes a pad 414, which is fixedly connected to the top of the slider 413. The top of the pad 414 abuts against the inner wall of the groove 22, and the pad 414 is made of a wear-resistant material. Specifically, the pad 414 can be fixedly connected to the top of the slider 413 by adhesive bonding or by a detachable connection with screws.

[0039] It can be seen that by setting the pad 414, when the slider 413 slides relative to the groove 22, the pad 414 slides together with it. The pad 414 reduces the wear of the slider 413. Specifically, the pad 414 is made of polytetrafluoroethylene (PTFE), which is wear-resistant, has a low coefficient of friction, and good shock resistance. The pad 414 not only reduces the wear of the slider 413 but also further reduces the friction of the slider 413's sliding motion and improves the overall shock resistance of the device.

[0040] Furthermore, the base plate 1 is provided with four mounting holes 23 arranged along the height direction, and the four mounting holes 23 are respectively arranged corresponding to the two first telescopic rods 31 and the two second telescopic rods 41.

[0041] It can be seen that, through the arrangement of the mounting holes 23, when the device needs to be transported, the first telescopic rod 31 and the second telescopic rod 41 can be removed and stored in the corresponding mounting holes 23. This allows the top plate 2 and the bottom plate 1 to be fully engaged during transportation, forming a square block, which facilitates the transport of the device. It is also worth noting that the mounting holes 23 are located on the top plate 2, and during use, the openings of the mounting holes 23 face downwards, making it less likely for water and dust to accumulate in the mounting holes 23.

[0042] Furthermore, it also includes a tilt sensor 5, which is detachably connected to the top plate 2; the top plate 2 is provided with a receiving groove 24, the tilt sensor 5 is installed in the receiving groove 24, and the tilt sensor 5 is completely embedded in the receiving groove 24.

[0043] It is known that the angle of the top plate 2 is detected by the tilt sensor 5, and the angle of the top plate 2 can be detected in real time during the adjustment of the top plate 2. Furthermore, the arrangement of the receiving groove 24 allows the top plate 2 and the bottom plate 1 to be easily fitted together during transportation, facilitating transport.

[0044] Furthermore, the top plate 2 is provided with a first threaded hole 25 and a second threaded hole 26. There are four first threaded holes 25, which are respectively arranged at the four corners of the top of the top plate 2. The second threaded hole 26 is arranged on the side of the top plate 2. The bottom plate 1 is provided with a third threaded hole 12, which is arranged on the side of the bottom plate 1.

[0045] Specifically, the first threaded hole 25, the second threaded hole 26, and the third threaded hole 12 are used to install lifting rings. When it is necessary to lift and move the top plate 2, lifting rings are installed on the four first threaded holes 25, and a crane is used to lift it through the lifting rings, facilitating the movement of the top plate 2. By installing lifting rings on the second threaded hole 26 and using a crane for lifting, it is convenient to flip the top plate 2. By installing lifting rings on the third threaded hole 12 and using a crane for lifting, it is convenient to move and flip the bottom plate 1.

[0046] Furthermore, the top plate 2 is provided with a rotatable handle 27, and the bottom plate 1 is provided with a slot 13. When the top plate 2 is closed on the bottom plate 1, the handle 27 rotates and engages in the slot 13. There are four handles 27, two of which are arranged on the first side of the top plate 2, and the other two are arranged on the second side of the top plate 2.

[0047] It is known that the handle 27 can be flipped, allowing manual movement of the top plate 2. A slot 13 is provided on the base plate 1; when the top plate 2 and base plate 1 are together, the handle 27 can be rotated to engage with the slot 13. At this point, when hoisting the top plate 2, the base plate 1 can be lifted together using the handle 27, facilitating the overall movement and handling of the device. Furthermore, during handling, the handle 27's engagement with the base plate 1 facilitates stacking without affecting adjacent devices.

[0048] Furthermore, a magnetic block 14 is arranged inside the card slot 13, the handle 27 is made of steel, and a finger groove 15 is provided on the base plate 1, which is connected to the card slot 13.

[0049] It is known that when the handle 27 is inserted into the slot 13, the magnetic block 14 attracts and fixes the handle 27, increasing the safety of the device during movement and preventing the handle 27 from turning out of the slot 13 under external interference, which would cause the base plate 1 to fall and cause a dangerous accident.

[0050] Furthermore, a positioning pin 16 is provided on the base plate 1, and a corresponding positioning hole 28 is provided on the top plate 2.

[0051] Specifically, four positioning pins 16 are arranged on the base plate 1, with each pin positioned at one of the four corners of the base plate 1. The positioning pins 16 are arranged along the height direction, and the top of each positioning pin 16 is chamfered. When the top plate 2 is closed with the base plate 1, the chamfered edges guide the positioning pins 16 to smoothly insert them into the positioning holes 28. This ensures that after the top plate 2 and the base plate 1 are closed, the four sides of the base plate 1 and the top plate 2 are flush, and that the handle 27 on the top plate 2 can smoothly rotate into the slot 13.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
