Description

Technical Field

[0001] The utility model belongs to the technical field related to bridge construction, in particular to a small curve radius bridge hanging basket cantilever with telescopic adjustment. Background Art

[0002] With the increase in the mileage of expressways, the number of mountain expressways and long-span rigid-frame bridges across mountains, rivers, railways, and highways has also increased. Due to the limitations of complex and narrow terrain and the need for line selection, curved continuous rigid-frame bridges are increasingly being used. Compared with straight continuous rigid-frame bridges, they have the characteristics of "bending and torsion coupling" and a more complex force form. During construction, their linear control is particularly critical. Therefore, they need to be supported by cantilevers to cooperate with pouring operations. However, in actual use, they still have the following disadvantages:

[0003] When the cantilever of a small curve radius bridge basket is working, the corresponding mounting structure is directly installed at a suitable position on the outside, and the bridge basket is hung through the cantilever during work. During operation, when the basket position is inaccurate and needs to be adjusted, it is not convenient to adjust the cantilever to the position outside the cast bridge;

[0004] When the cantilever of the bridge with a small curve radius is in operation, the corresponding cantilever is directly used for operation, and the hanging basket is hung during the operation. During the cantilever assembly process, it is directly installed through multiple installation bolts, which makes installation and disassembly inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide a small curve radius bridge hanging basket cantilever with telescopic adjustment. By arranging a fixing rod, a pushing block, a positioning plate and an external fixing strip, the utility model solves the problems that it is not convenient to adjust the position of the cantilever extending out of the cast bridge during work, and the cantilever is troublesome to install and disassemble.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a cantilever of a bridge hanging basket with a small curve radius with telescopic adjustment, comprising a fixing rod, a pushing block, a positioning plate and an external fixing strip, the top and bottom ends of the fixing rod are fixed with a movable sleeve, the movable sleeve is movably connected with a pushing block, the edge of the movable sleeve away from the pushing block is movably connected with a positioning plate, the positioning plate is threadedly connected with a pushing bolt, and the pushing bolt is fixed with a rotating block at one end close to the pushing block, and the two pushing blocks are fixed with an external fixing strip at one end away from the positioning plate. When working, the movable sleeve is movably connected to the pushing block and the positioning plate through the fixing rod, and the position between the fixing rod and the external fixing strip is changed when the pushing block works, and the pushing bolt is threadedly connected thereto through the positioning plate, and the position of the pushing block is changed when the pushing bolt is rotated, and the upper cantilever and the lower cantilever are connected together when the external fixing strip works.

[0008] Furthermore, the upper and lower parts of one side of the positioning plate are both threadedly connected with mounting bolts, the movable sleeve is provided with a socket corresponding to the position of the socket, the mounting bolt is inserted into the socket, and the two mounting bolts in the same positioning plate are respectively arranged above and below the pushing bolt in the positioning plate. When the positioning plate is working, the positioning plate and the movable sleeve are installed together by the mounting bolts.

[0009] Furthermore, a connecting cavity is fixed on one end of the pushing block close to the positioning plate, and a movable hole is opened in the center of the end of the connecting cavity away from the pushing block. The rotating block is movably connected in the movable hole. When the pushing block is working, the rotating block is movably connected through the movable hole on the connecting cavity.

[0010] Furthermore, an upper cantilever is fixed at the upper edge of the outer fixing bar away from the pushing block, and a lower cantilever is fixed at the lower edge of the outer fixing bar away from the pushing block. When the outer fixing bars move together, the upper cantilever and the lower cantilever cooperate to support the supporting structure of the hanging basket.

[0011] Furthermore, the upper cantilever is arranged horizontally, and the lower cantilever is arranged inclined, and the upper cantilever and the lower cantilever are fixed to each other at one end away from the external fixing bar, and the upper cantilever and the lower cantilever are commonly fixed with a mounting block at one end away from the external fixing bar, and the upper cantilever and the lower cantilever are mounted on the support structure through the mounting block.

[0012] Furthermore, a rear support frame is fixed to the top surface of the movable sleeve located above and the bottom surface of the movable sleeve located below. Three equidistant mounting plates are fixed to the bottom of the rear support frame, and the rear support frame is installed in a suitable position through the mounting plates.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that it is inconvenient to adjust the position of the cantilever of the bridge hanging basket with a small curve radius to the outside of the cast bridge during work by arranging a fixing rod, a pushing block, a positioning plate and an external fixing bar. The rotating block is movably connected through the movable hole on the connecting cavity, and the rotating block is stuck in the movable hole. When the pushing bolt is rotated during work, the position of the pushing block in the movable sleeve is changed, so that the position between the external fixing bar and the rear support frame can be finely adjusted, making it more convenient to adjust the position of the cantilever of the bridge hanging basket with a small curve radius to the outside of the cast bridge during work.

[0015] The utility model solves the problem of troublesome installation and disassembly of the cantilever of a bridge hanging basket with a small curve radius by arranging a fixing rod, a pushing block, a positioning plate and an external fixing strip. After aligning the corresponding mounting structure with the mounting plate, the mounting bolts are inserted into the mounting plate and then screwed into the external walking equipment mounting position to complete the installation between the support frame and the walking equipment mounting structure. During operation, the hanging basket is installed together with the mounting blocks on the upper and lower cantilever. When it is necessary to disassemble the rear support frame, it is first installed on the upper cantilever through the hanging structure of the crane, and the mounting bolts can be unscrewed on the mounting plate. After lifting the cantilever, until the cantilever is hoisted to the disassembly position, the mounting bolts in the positioning plate can be unscrewed, and the fixing rod and the external fixing strip can be separated, so that the fixing rod and the external fixing strip can be disassembled from each other, making the installation and disassembly of the cantilever of the bridge hanging basket with a small curve radius more convenient.

Specific embodiment 1

[0026] See also Figure 1-6 The utility model is a cantilever of a small curve radius bridge hanging basket with telescopic adjustment, comprising a fixing rod 1, a pushing block 2, a positioning plate 3 and an outer fixing bar 4. The top and bottom ends of the fixing rod 1 are fixed with movable sleeves 101. When the fixing rod 1 is working, the two movable sleeves 101 are fixed thereon, and the pushing block 2 is movably connected therein through the movable sleeve 101. The pushing block 2 is movably connected inside the movable sleeve 101. When the pushing bolt 302 is rotated by the pushing block 2, the position between the fixing rod 1 and the outer fixing bar 4 is changed, and the movable sleeve 101 is away from the pushing block 2. A positioning plate 3 is movably connected to the edge of the block 2, and the position of the pushing block 2 is limited by the positioning plate 3. A pushing bolt 302 is threadedly connected to the positioning plate 3. When the pushing bolt 302 is rotated, the position of the pushing block 2 is changed. A rotating block 303 is fixed to the end of the pushing bolt 302 close to the pushing block 2, and the rotating block 303 is connected to the connecting cavity 201. The ends of the two pushing blocks 2 away from the positioning plate 3 are jointly fixed with an external fixing bar 4, and the upper cantilever 401 and the lower cantilever 402 are connected together by the external fixing bar 4.

[0027] Specifically, the upper and lower parts of one side of the positioning plate 3 are threadedly connected with mounting bolts 301, and the movable sleeve 101 is provided with a socket 102 corresponding to the position of the socket 102. The mounting bolt 301 is inserted into the socket 102, and the two mounting bolts 301 in the same positioning plate 3 are respectively arranged above and below the pushing bolt 302 in the positioning plate 3. When the positioning plate 3 is working, it enters the two movable sleeves 101 respectively through the two positioning plates 3 until the side of the positioning plate 3 away from the outer fixing bar 4 is flush with the end face of the movable sleeve 101 away from the outer fixing bar 4. At this time, the mounting bolt 301 is inserted into the socket 102, and screwed into the positioning plate 3 and tightened, so that the positioning plate 3 is fixed in the movable sleeve 101.

[0028] Furthermore, a connecting cavity 201 is fixed to one end of the pushing block 2 close to the positioning plate 3, and a movable hole 202 is opened in the center of the end of the connecting cavity 201 away from the pushing block 2, and the rotating block 303 is movably connected in the movable hole 202. When the pushing block 2 is working, the rotating block 303 is movably connected through the movable hole 202 on the connecting cavity 201, and the rotating block 303 is stuck in the movable hole 202, so that when working, when the pushing bolt 302 is rotated, the position of the pushing block 2 in the movable sleeve 101 is changed.

[0029] The operation process of this embodiment is as follows: when working, align the end of the pushing block 2 on the outer fixing bar 4 away from the outer fixing bar 4 with the movable sleeve 101, and then enter the two movable sleeves 101 respectively through the two positioning plates 3 until the side of the positioning plate 3 away from the outer fixing bar 4 is flush with the end surface of the movable sleeve 101 away from the outer fixing bar 4. At this time, insert the mounting bolt 301 into the insertion hole 102, screw it into the positioning plate 3 and tighten it, so that the positioning plate 3 is fixed in the movable sleeve 101, and the rotating block 303 is movably connected through the movable hole 202 on the connecting cavity 201, and the rotating block 303 is stuck in the movable hole 202, so that when working, when the pushing bolt 302 is rotated, the position of the pushing block 2 in the movable sleeve 101 is changed, so that the position between the outer fixing bar 4 and the rear support frame 5 can be finely adjusted.

The outer fixing bar 4 forms a triangle by combining with the upper cantilever 401 and the lower cantilever 402 to increase the stability of the support.

[0031] Specifically, the upper cantilever 401 is arranged horizontally and the lower cantilever 402 is arranged inclined. The upper cantilever 401 and the lower cantilever 402 are fixed to each other at one end away from the external fixing bar 4, and the upper cantilever 401 and the lower cantilever 402 are commonly fixed with a mounting block 403 at one end away from the external fixing bar 4.

[0032] Furthermore, a rear support frame 5 is fixed to the top surface of the movable sleeve 101 located above and the bottom surface of the movable sleeve 101 located below. Three equidistant mounting plates 501 are fixed to the bottom of the rear support frame 5, which is supported on the bridge track through the rear support frame 5. The rear support frame 5 is installed on the equipment that drives the movement through the mounting plates 501, so that the hanging basket is supported on it when working.

[0033] The operating process of this embodiment is as follows: when working, after aligning the corresponding mounting structure with the mounting plate 501, the mounting bolts are inserted into the mounting plate 501, and then screwed into the external walking equipment mounting position to complete the installation between the support frame 5 and the walking equipment mounting structure. When working, the mounting blocks 403 on the upper cantilever 401 and the lower cantilever 402 are installed together with the hung hanging basket. When it is necessary to disassemble the rear support frame 5, first install it on the upper cantilever 401 through the hanging structure of the crane, then unscrew the mounting bolts on the mounting plate 501, lift the cantilever, and after the cantilever is hoisted to the disassembly position, unscrew the mounting bolts 301 in the positioning plate 3, and then separate the fixing rod 1 and the outer fixing bar 4, so that the fixing rod 1 and the outer fixing bar 4 are disassembled from each other.
