Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a guide frame for positioning a steel casing. Background Art

[0002] At present, in bridge construction, bridge piers are generally built using underwater bored pile construction methods, and the insertion of steel casing is a crucial part of its construction process. After the steel casing contacts the seabed, a vibrating hammer is used to insert the steel casing until the insertion depth of the steel casing meets the requirements of the construction drawing design. Among them, the positioning quality of the steel casing directly determines the quality of the bridge pier. When inserting a high-height steel casing, a double-layer guide frame is usually used to guide and adjust the steel casing to ensure that the center of the steel casing coincides with the center of the pile position.

[0003] In the related art, a guide frame has been used to assist in the lowering and positioning of the steel casing. The guide frame is generally provided with an adjustment structure. After the steel casing is lowered into the guide frame, the adjustment structure is used to fine-tune the steel casing until it coincides with the center of the pile position to meet the requirements.

[0004] However, there will be an error between the actual position and the theoretical position of the steel casing during the adjustment process, and after the adjustment is completed, it is necessary to strictly ensure that the plane position deviation of the steel casing is less than 5 cm and the verticality deviation is less than 1%, so that the drilling rig can work smoothly along the vertical direction of the pile position. The current guide frame has poor accuracy during adjustment due to the lack of intuitiveness, and the steel casings used in different environments may have large differences in diameter, height, etc., and the current guide frame cannot meet the insertion and positioning of steel casings of different sizes, and has poor versatility.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] The embodiment of the present application provides a guide frame for positioning a steel casing, which can solve the problems in the related art that the guide frame has low adjustment and positioning accuracy and is not intuitive enough during adjustment.

[0033] See also Figure 1 As shown, the frame includes two horizontal positioning frames 11 arranged in an aligned manner with an interval up and down, and a plurality of positioning rods 10 are arranged vertically and spaced apart between the two horizontal positioning frames 11. A plurality of adjustment components 12 are arranged spaced apart on each horizontal positioning frame 11, and the adjustment components 12 are used to adjust the position of the steel casing to ensure that the central axis of the steel casing can coincide with the central axis of the pile position. The alignment mechanism mainly includes a positioning component and an alignment component. The alignment component is used to be arranged on the platform where the frame is located, and is used to emit at least two intersecting laser beams toward the center of the pile position, that is, the intersection point of different laser beams is the center of the pile position. The positioning component is used to be arranged on the steel casing and its central axis coincides with the central axis of the steel casing. The positioning component is configured such that when the positioning component receives the laser emitted by the alignment component, the central axis of the positioning component and the pile position coincide. Since the positioning component is used to receive the laser, and its center coincides with the center of the steel casing, when the positioning component cannot fully receive the laser, it means that the position of the steel casing has not been adjusted properly. At this time, the adjusting component 12 is used to adjust the steel casing, and the positioning component is adjusted accordingly. When the position of the positioning component is adjusted to fully receive the laser, it means that the position of the steel casing is adjusted in place.

[0034] Further, the positioning assembly specifically includes a first positioning member 20 and a plurality of second positioning members 21 of different sizes. One of the second positioning members 21 is detachably arranged on the top of the steel casing and its central axis overlaps with the central axis of the steel casing. The first positioning member 20 is arranged at the central axis of the second positioning member 21 and is used to receive the laser emitted by the alignment assembly. The second positioning member 21 here includes at least two rods whose centers intersect at one point. From the perspective of structural stability, the number of rods of the second positioning member 21 is 3, all of which are in the same plane and are integrally formed at the center. Second positioning members 21 of different sizes are used to adapt to steel casings with different directness.

[0035] For details, see Figure 3-Figure 4 As shown, the first positioning member 20 includes a positioning seat 22, a positioning box 23 and at least two laser sensors, wherein the positioning seat 22 is detachably rotatably arranged on the second positioning member 21, and its central axis coincides with the central axis of the second positioning member 21, the positioning box 23 is in the shape of a hollow cube and is covered on the positioning seat 22, and the centers of at least two adjacent sides of the positioning box 23 are provided with vertically arranged long strip positioning holes 24, and the two laser sensors are both arranged on the positioning seat 22 and located in the positioning box 23, and are used to respectively receive the corresponding lasers emitted by the alignment component, and the two laser sensors are configured such that when the two laser sensors respectively receive the corresponding lasers emitted by the alignment component, the central axis of the positioning seat 22 coincides with the central axis of the pile position. Therefore, the number of positioning holes 24 here corresponds to the number of lasers, and since the volume of the steel casing is generally large, from the perspective of accuracy, the alignment component emits four intersecting laser beams toward the center of the pile position, and the angle between each two adjacent laser beams is 90°, and the number of corresponding positioning holes 24 is 4. In addition, in order to facilitate the reception of laser, the horizontal plane of the positioning box 23 is higher than the top of the steel casing, and because the central axis of the steel casing may have coincided with the central axis of the pile position, but the four positioning holes 24 can only receive lasers in a specific direction, the positioning seat 22 can be rotated according to the alignment situation at this time, which is convenient for adjustment.

[0036] Furthermore, the sides of the positioning box 23 with the positioning holes 24 are coated with a layer of black paint, and the sides are also provided with a first horizontal scale line. During the adjustment process, the laser can only be received when the positioning holes 24 on the positioning box 23 are aligned with the corresponding laser. Therefore, the laser may fall on the side of the positioning box 23 in the early stage of adjustment. In order to facilitate the adjustment personnel to observe the positional relationship and distance between the laser and the corresponding positioning hole 24, a layer of black paint is coated on the side of the positioning box 23 to help the adjustment personnel to observe the position of the laser more intuitively. In addition, the first horizontal scale line is perpendicular to the positioning hole 24, which can tell the adjustment personnel the approximate distance that needs to be adjusted.

[0037] For further information, see Figure 2As shown, in order to adapt to the positioning of steel casings of different heights and diameters, the horizontal positioning frame 11 located at the top of the guide frame is inserted on the positioning rod 10 and can move along the length direction of the positioning rod 10, and the horizontal positioning frame 11 located at the bottom is fixedly connected to the positioning rod 10. The dimensions of the two horizontal positioning frames 11 along their length and width directions can be adjusted to adapt to the positioning of steel casings with different sizes. Specifically, the positioning rod 10 is provided with a plurality of positioning grooves at intervals along its length direction, and each positioning rod 10 also includes a fixing member matching the positioning groove, and the fixing member is used to be detachably arranged in one of the positioning grooves to support and fix the horizontal positioning frame 11 that can move along the length direction of the positioning rod 10. The fixing member is symmetrical and the adjacent sides are hinged to each other. The top and bottom are provided with convex edges extending outwards, which are used to support and fix the horizontal positioning frame 11 located at the top. When the horizontal positioning frame 11 located at the top needs to be adjusted, the position of the horizontal positioning frame 11 is adjusted along the positioning rod 10, and the position of the fixing member is adjusted accordingly. In addition, a detachable diagonal rod is provided between the positioning rods 10, which is used to enhance the stability of the overall structure. After the entire guide frame is installed and fixed, a connecting reinforcement rod will also be provided between the horizontal positioning frame 11 and the positioning rod 10. In order to facilitate the mediators to come up, a ladder is also provided on one side of the horizontal positioning frame 11 located above.

[0038] Furthermore, the horizontal positioning frame 11 includes four channel steels, and every two adjacent channel steels are vertically arranged to surround a fixing hole 13. Each channel steel can be telescopic along its length direction, and a second horizontal scale line is provided on the telescopic overlapping section to facilitate the adjustment personnel to adjust the length of the channel steel according to the size of different steel casings.

[0039] Furthermore, since the steel casing has a certain height, and the positioning box 23 can only position the horizontal positioning frame 11 located above, the steel casing may be skewed. A level 25 is provided on the top of the positioning box 23. The level 25 can be used to better judge whether the steel casing is vertical, which is convenient for adjustment. In addition, a guardrail with a certain height is also provided on the horizontal positioning frame 11 located above to ensure the safety of the adjuster during adjustment.

[0040] Furthermore, a voice control component is provided in the positioning box 23, and the voice control component is connected to the laser sensor. The voice control component is used to issue an alignment prompt after all laser sensors have received the corresponding lasers, so as to promptly remind the adjuster that the adjustment has been made.

[0041] For further information, see Figure 5As shown, the adjustment component 12 is detachably arranged on the channel steel, and the adjustment component 12 includes a driving member 14 and a roller 15. The side surface of the roller 15 is a curved surface concave toward its axial direction, and the curved surface matches the side size of the steel casing. The driving member 14 is used to drive the roller 15 to move away from or close to itself.

[0042] For further information, see Figure 6 As shown, since the entire guide frame is large in size and heavy in weight, a plurality of running wheels 16 are provided at intervals at the bottom of the horizontal positioning frame 11 located below. The running wheels 16 can be folded up or down to facilitate the movement or position adjustment of the guide frame.
