Description

Technical Field

[0001] This invention relates to the field of cantilever beam casting construction technology, specifically a roughening platform for the beam end of a railway cantilever beam. Background Technology

[0002] After the steel formwork is erected on the bridge pier, concrete is poured into the formwork. After a period of time, the concrete in the formwork solidifies, and the cantilever beam is formed. Then, the cross-section of the cantilever beam is roughened to make the end face easier for the next stage of pouring construction.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figure 1-8 The present invention provides a technical solution: a railway cantilever beam end roughening platform, comprising a cantilever beam body 1 erected on a bridge pier and a steel mold 2 for casting and forming the cantilever beam body 1, and further comprising:

[0053] Construction platform 3 is set at the beam end of the cantilever beam body 1;

[0054] The erection unit 4 is set between the construction platform 3 and the steel formwork 2, and is used to erect the construction platform 3 at the beam end of the cantilever beam body 1;

[0055] The roughening unit 5 is set on the construction platform 3 and is used to roughen the beam end of the cantilever beam body 1, which is formed by concrete pouring in the steel mold 2.

[0056] The erection unit 4 includes:

[0057] The installation mechanism 41 is installed on the steel mold 2 and is used to support the erection unit 4 and the construction platform 3.

[0058] The adjustment mechanism 42 is installed on the installation mechanism 41 and is used to adjust the horizontal and vertical positions of the construction platform 3 so that the roughening unit 5 can complete the roughening of the entire beam end face.

[0059] The installation mechanism 41 includes:

[0060] Two sets of locking blocks 411 are symmetrically arranged on both sides of the steel mold 2 and are locked onto the steel mold 2;

[0061] Two sets of mounting plates 412 are respectively mounted on two sets of clips 411;

[0062] Four sets of electric telescopic arms 413 are symmetrically fixed in the lateral position of the two sets of mounting plates 412. In actual use, they are used to realize the lateral movement of the mounting frame 414 so as to adjust the lateral position of the mounting frame 414, thereby making the roughening unit 5 and the beam end face of the cantilever beam body 1 fit together.

[0063] The mounting frame 414 is provided at the beam end of the cantilever beam body 1, and the construction platform 3 is provided inside the mounting frame 414;

[0064] A connecting component is disposed between the four sets of electric telescopic arms 413 and the mounting frame 414, for the mounting frame 414 to slide on the electric telescopic arms 413.

[0065] In addition, the connecting component is configured as a slide rod 415, one end of which is fixed to the mounting frame 414, and the other end passes through the end of the electric telescopic arm 413 and slides thereon. A limit piece 416 is provided at the end of the slide rod 415.

[0066] Meanwhile, the adjustment mechanism 42 includes:

[0067] A longitudinal moving component 421 is disposed between the electric telescopic arm 413 and the mounting frame 414, and is used to drive the mounting frame 414 to move longitudinally.

[0068] A vertical moving part 422 is disposed between the construction platform 3 and the mounting frame 414 for adjusting the height of the mounting frame 414. In actual use, the vertical moving part 422 is configured as a scissor lift.

[0069] The longitudinal moving member 421 includes:

[0070] Mounting block 4211 with threaded hole is provided at the upper end of mounting frame 414;

[0071] A threaded rod 4212 is threaded onto the mounting block 4211, and a rotating motor 4213 is provided at the end of the threaded rod 4212. The rotating motor 4213 is fixedly mounted on the electric telescopic arm 413.

[0072] During the roughening operation, the device is first secured to the steel mold 2 by the locking block 411. Then, the distance between the roughening unit 5 and the end face of the cantilever beam 1 is adjusted by the electric telescopic arm 413 so that the roughening unit 5 can perform roughening operations on the end face of the beam normally. Before the roughening operation, the construction platform 3 is moved to one side of the beam end face by the longitudinal moving part 421, and at the same time, the vertical moving part 422 moves the construction platform 3 to the uppermost position. Then, the vertical moving part 422 continues to work, so that the construction platform 3 moves from top to bottom. At the same time, the roughening unit 5 works, so as to complete a vertical roughening operation. Then, the construction platform 3 is raised to the initial height by the vertical moving part 422, and then moved longitudinally upwards by a distance. Then, the above operation is repeated, and the roughening operation is carried out from top to bottom, so as to complete the entire roughening operation.

[0073] In addition, the chiseling unit 5 includes:

[0074] The roughening machine box 51 is fixedly mounted on the construction platform 3;

[0075] At least two sets of chisel rods 52 are arranged vertically and horizontally on the chisel box 51. Each set of chisel rods 52 includes multiple chisel rods 52. The chisel rods 52 are arranged vertically and horizontally. During the above-mentioned top-down chisel operation, the accuracy of the chisel operation can be improved, thereby improving the chisel quality.

[0076] At least two sets of mounting strips 53 are fixed to the chiseling machine box 51, and the number of them is the same as the number of chiseling rods 52. The chiseling rods 52 are slidably mounted on the mounting strips 53.

[0077] At least two sets of power mechanisms 54 are installed in the chiseling machine box 51 to drive the chiseling rods 52 in the same set to perform synchronous telescopic movements in order to chisel the beam end face of the cantilever beam body 1.

[0078] Meanwhile, the power mechanism 54 includes:

[0079] Multiple rotating rods 541, one end of which is rotatably connected to the inner end of the chisel rod 52, and the other end is rotatably connected to a fixing strip 542. The fixing strip 542 is fixed inside the chisel box 51, and the rotating rods 541 rotate at a fixed point on the chisel box 51.

[0080] The swing assembly is disposed between the fixed bar 542 and the plurality of rotating rods 541, and is used to drive the rotating rods 541 to swing periodically so as to realize the extension and retraction of the chisel rod 52.

[0081] The swing component includes:

[0082] A connecting plate 543 is slidably disposed on the mounting strip 53. A plurality of sliding shafts 544 are disposed on the connecting plate 543. A swing groove 545 for sliding the sliding shafts 544 is disposed on the rotating rod 541. The number of the sliding shafts 544 is the same as the number of the chisel rods 52 in the same group.

[0083] A movable plate 546 is fixedly mounted on a connecting plate 543, and a movable slide groove 547 is provided on the movable plate 546.

[0084] The rotating shaft 548 is slidably disposed within the movable groove 547;

[0085] The power component 549 is mounted on the rotating shaft 548 and is used to drive the rotating shaft 548 to rotate 360 ​​degrees periodically.

[0086] Among them, power component 549 includes:

[0087] A rotating frame 5491 is mounted on the mounting strip 53. A moving motor 5492 is fixedly mounted on the rotating frame 5491. A rotating plate 5493 is provided at the rotating end of the moving motor 5492. The other end of the rotating plate 5493 is connected to the rotating shaft 548.

[0088] During the chiseling operation, the moving motor 5492 drives the rotating shaft 548 to rotate, thereby sliding within the moving groove 547 in the moving plate 546. This causes the moving plate 546 to slide periodically, which in turn causes the connecting plate 543 to slide periodically. Consequently, the sliding shaft 544 on the connecting plate 543 slides within the swing groove 545, thereby driving the rotating shaft rod to swing periodically, thus achieving the extension and retraction of the chiseling rod 52.

[0089] In addition, each of the sliding shafts 544 is slidably mounted on the connecting plate 543 in the vertical direction. A connecting strip 6 is provided on the sliding shaft 544, and an electric telescopic rod 61 is provided at the end of the connecting strip 6 away from the sliding shaft 544. This is used in actual operation so that when the chisel is located on both sides of the cross section and the chisel rod 52 is not in contact with the chisel surface, the sliding shaft 544 is disengaged from the swing groove 545, so that the chisel rod 52 corresponding to the sliding shaft 544 does not perform telescopic work, thereby reducing the power load of the moving motor 5492.

[0090] Finally, a limiting plate 7 is provided on the side of the chisel rod 52 near the inner wall of the chisel box 51, and a pressing spring 8 is sleeved on the chisel rod 52 located between the limiting plate 7 and the mounting strip 53.

[0091] The spring serves two purposes: firstly, it can buffer and eliminate the reaction force of the chiseling rod 52 during the chiseling operation; secondly, when the sliding shaft 544 disengages from the swing groove 545, it can ensure that the chiseling rod 52 and the rotating rod 541 are on the same straight line, thus facilitating the re-alignment and insertion of the sliding shaft 544 into the swing groove 545, and thus making the insertion position fixed.
