Description

Technical Field

[0001] The utility model relates to the field of Bailey sheet processing, and more specifically, to a fixing fixture based on Bailey sheet processing. Background Art

[0002] A Bailey span, also known as a Bailey frame or Bailey beam, is a truss structure consisting of welded upper and lower chords, vertical members, and diagonal members. It is typically made of 16Mn steel, and each span weighs approximately 270 kg. Its construction is sophisticated, with male and female joints and pestle-shaped connecting pin holes at the ends of the upper and lower chords, and a steel plate with a circular hole welded to the lower chord. Bailey spans offer advantages such as simple structure, convenient transportation, rapid erection, high load capacity, and strong interchangeability and adaptability. They can accommodate a variety of loads. The clear width of the bridge deck is typically 3.7 meters, and they can be assembled into simply supported or continuous beam bridges with various spans ranging from 9 to 63 meters. Bailey spans are also used to assemble gantry cranes, guide beams, bridge erection machines, hanging baskets, and other equipment, playing a vital role in on-site construction operations such as bridge construction.

[0003] At present, when processing Bailey pieces, two clamps are generally used to clamp the two sides of the mother-of-pearl piece to fix it. In order to facilitate the processing of both sides, a motor is installed on one clamp to drive it, and the other clamp is rotatably connected to the support component through a bearing. This results in that after the reverse side of the motor is completed, it is still necessary to manually fix the angle of the clamp connected to the bearing (generally, the angle of this surface is fixed by installing screws on the bearing) to avoid loosening of this end during Bailey piece processing, thereby greatly increasing the workload of the staff and having poor use effect.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a fixing fixture based on Bailey sheet processing. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a fixing fixture based on Bailey sheet processing.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a fixing fixture based on Bailey sheet processing, comprising a support seat, wherein one side of the top of the support seat is fixedly connected to a motor A through a support column A, a clamp A is fixedly connected to the transmission end of the motor A, a reciprocating mechanism is installed on the other side of the top of the support seat, and the transmission end of the reciprocating mechanism is fixed to the clamp B through a support column B.

[0007] Preferably, a groove A is provided on one side of the top of the support seat, and the reciprocating mechanism includes a reciprocating screw arranged inside the groove A and driven by a motor B. A rod sleeve is threadedly connected to the outer wall of the reciprocating screw, and the support column B is fixed to the top of the rod sleeve. The interior of the groove A is located on both sides of the reciprocating screw with guide rails fixedly connected, and the two sides of the rod sleeve are slidably connected to the guide rails through sliders.

[0008] Preferably, a support assembly is installed in the middle of the support seat to support the Bailey sheet before it is fixed.

[0009] Preferably, the support assembly includes an electro-hydraulic rod fixed on a support seat, and the head of the electro-hydraulic rod is fixedly connected to a support platform.

[0010] Preferably, a groove B is provided in the middle portion of the top end of the support seat, and the electric hydraulic rod is located in the support platform to expand the installation space.

[0011] Preferably, the heights of the support columns A and B are adjustable and can be adjusted as needed.

[0012] Preferably, the support column A and the support column B are both composed of an outer column and an inner column. A through hole is provided on the upper portion of the outer wall of the outer column, and a plurality of screw holes are provided on the outer wall of the inner column in a vertical array to fix the height of the outer column and the inner column.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The utility model moves the Bailey sheet to a position where it does not hinder the rotation of the Bailey sheet through a reciprocating mechanism, and then the Bailey sheet is driven by the motor A to rotate to turn the Bailey sheet over. After the turning is completed, the reciprocating mechanism resets the clamp B, so that one end of the Bailey sheet is clamped by the clamp B again, and the Bailey sheet on the other side can be processed. In this way, the setting of the bearing is eliminated. The movement of the reciprocating mechanism makes it possible to turn the Bailey sheet over without the need for the clamp B to be rotated with the supporting component, and the reciprocating mechanism can be controlled by the motor and does not require manual operation, which helps to save manpower and has a better use effect, thereby solving the problem in the background technology that manual work is required to fix the angle of the clamp connected to the bearing to avoid loosening of this end during Bailey sheet processing, thereby greatly increasing the workload of the staff and having poor practicality.

[0015] 2. The support base of the utility model is equipped with a support assembly in the middle, which can support the Bailey piece before it is fixed. In this way, when clamping, the staff does not need to hold it with their hands all the time, which helps to save manpower;

[0016] 3. The utility model installs the electric hydraulic rod in the groove B, which expands the installation space and avoids the situation where it is installed directly on the top of the support base, which will cause obstruction to the turning over of the Bailey piece even if the support platform is lowered to the bottom;

[0017] 4. The heights of the support columns A and B of the present invention can be adjusted, so that the height at which the clamping pieces are fixed can be adjusted according to processing requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] like Figure 1-4 As shown, the utility model provides a fixing jig based on Bailey sheet processing, including a support base 1, a top side of the support base 1 is fixedly connected to a motor A3 through a support column A2, a driving end of the motor A3 is fixedly connected to a clamp A4, a reciprocating mechanism 5 is installed on the other side of the top of the support base 1, and the driving end of the reciprocating mechanism 5 is fixed to the clamp B7 through a support column B6.

[0025] During use, the Bailey piece to be processed is placed between the clamp A4 and the clamp B7, and then the two clamps are controlled to clamp the two ends of the Bailey piece respectively to fix the Bailey piece, so as to process the Bailey piece. When the Bailey piece needs to be turned over, first release the fixation of the Bailey piece by the clamp B7, and then move it to a position that does not hinder the rotation of the Bailey piece through the reciprocating mechanism 5. Then the motor A3 drives the rotation of the Bailey piece to turn the Bailey piece over. After the turning over is completed, the reciprocating mechanism 5 resets the clamp B7, so that one end of the Bailey piece is clamped again by the clamp B7, and the Bailey piece on the other side can be processed. In this way, the bearing setting is eliminated. Through the movement of the reciprocating mechanism 5, the clamp B7 does not need to be rotated with the support component to turn the Bailey piece over, and the reciprocating mechanism 5 can be controlled by the motor and does not require manual operation, which helps to save manpower and achieve better use effect.

[0026] Furthermore, the height of the support column A2 and the support column B6 can be adjusted, so that the height of the clamping piece can be adjusted according to the processing needs. It should be noted that the height of the clamp supported by the support column A2 and the support column B6 needs to be consistent, so that the Bailey piece can be clamped horizontally for easy processing. The following is the specific structure of the support column A2 and the support column B6: The support column A2 and the support column B6 are both composed of an outer column 10 and an inner column 11. A through hole 12 is opened on the upper part of the outer wall of the outer column 10. A plurality of screw holes 13 are provided on the outer wall of the inner column 11 in a vertical array. That is, by pulling the inner column 11 up and down, the inner column 11 moves up and down along the outer column 10 to adjust the support height of the clamp (clamp A4 and clamp B7). When the height adjustment is completed, a large screw is passed through the through hole 12 on the outer column 10 and then rotated clockwise to install it into the screw hole 13 of the corresponding height on the inner column 11, so that the height of the support column A2 or the support column B6 can be fixed to fix the clamping height of the Bailey plate.

[0027] The support assembly 8 comprises an electric hydraulic rod 81 fixed on the support seat 1, and the head of the electric hydraulic rod 81 is fixedly connected to a support platform 82, that is, the electric hydraulic rod 81 drives the support platform 82 to move up and down, so that when support is needed, the support platform 82 is moved upward to support the Bailey sheet, and then the support platform 82 is lowered after support is completed to avoid affecting the flipping of the Bailey sheet. At the same time, a groove B14 is provided in the middle part of the top of the support seat 1, and the electric hydraulic rod 81 is located in the support platform 82. In this way, the electric hydraulic rod 81 is installed in the groove B14, which expands the installation space (the electric hydraulic rod 81 itself has a certain height) and avoids being directly installed on the top of the support seat 1. Even if the support platform 82 drops to the bottom, it will still block the flipping of the Bailey sheet.

[0028] At the same time, the utility model also provides a specific structure of the reciprocating mechanism 5: a groove A9 is opened on one side of the top of the support seat 1, and the reciprocating mechanism 5 includes a reciprocating screw rod 52 arranged inside the groove A9 and driven by a motor B51. A rod sleeve 53 is threadedly connected to the outer wall of the reciprocating screw rod 52, and the support column B6 is fixed to the top of the rod sleeve 53. The inside of the groove A9 is located on both sides of the reciprocating screw rod 52 and is fixedly connected to guide rails 54. The two sides of the rod sleeve 53 are slidably connected to the guide rails 54 through sliders 55.

[0029] That is, the motor B51 drives the reciprocating screw 52 to rotate, the reciprocating screw 52 drives the rod sleeve 53 to move back and forth, the rod sleeve 53 drives the slider 55 to move back and forth, and the slider 55 slides along the guide rail 54 to maintain the linear movement of the rod sleeve 53. The rod sleeve 53 can drive the clamp B7 to move back and forth linearly through the support column B6 to cooperate with the flipping of the Bailey piece.

[0030] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
