Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and more particularly to a support for bridge construction. Background Art

[0002] During the construction of the bridge cap beam, pouring concrete is a delicate and demanding task. When pouring the main beam, a bridge frame is often needed, and the bridge frame needs to be dismantled after pouring. Currently, during the dismantling process of the bridge frame, multiple large jacking equipment is installed on the column clamp to support the bridge frame. The support is stable, but the operation procedure is cumbersome.

[0003] The prior art discloses a disassembly device for a bridge frame, wherein a column clamp is installed on the column, and a disassembly device is arranged between the bridge frame and the column clamp; the disassembly device comprises a top plate at the upper end and a bottom plate at the lower end; a vertical plate is arranged between the top plate and the bottom plate; the top plate comprises a first support plate, and a first baffle is arranged at both ends of the first support plate, and a first inclined surface is arranged at both sides of the first support plate; the bottom plate comprises a second support plate, and a second baffle is arranged at both ends of the second support plate, and a second inclined surface is arranged at both sides of the second support plate; the vertical plate is installed between the first inclined surface and the second inclined surface, and a fastening device is arranged between the vertical plates, and the device is easy to operate. However, when the fastening device fails, the bridge frame will fall quickly, which is easy to cause production accidents. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that the bridge frame will fall quickly and easily cause safety accidents, and to provide a bracket for bridge construction to prevent the bridge frame from falling quickly and not easily cause safety accidents.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A bracket for bridge construction is provided, comprising a base plate, a first push plate, a second push plate, a ladder member and an adjustment mechanism for allowing the first push plate and the second push plate to move relative to each other, the first push plate and the second push plate are arranged opposite to each other, the first push plate and the second push plate are both slidably connected to the base plate, the ladder member is slidably connected to the first push plate and the second push plate, the ladder member has a first inclined surface and a second inclined surface, the first inclined surface is arranged opposite to the second inclined surface, the first push plate has a third inclined surface, the second push plate has a fourth inclined surface, the first inclined surface abuts against the third inclined surface, and the second inclined surface abuts against the fourth inclined surface; the adjustment mechanism is arranged on the base plate and is connected to the first push plate and the second push plate.

[0006] The support for bridge construction of the present invention drives the first push plate and the second push plate to move toward or away from each other through the adjustment mechanism, so that the first inclined plane slides with the third inclined plane, and the second inclined plane slides with the fourth inclined plane, driving the inverted ladder member to move up and down, and adjusting the height of the inverted ladder member. When the adjustment mechanism fails, the inverted ladder member falls downward, the first inclined plane slides relatively with the third inclined plane, and the second inclined plane slides relatively with the fourth inclined plane, and the sliding friction force of the surface contact prevents the inverted ladder member from falling downward quickly, thereby preventing the bridge frame from falling quickly and not easily causing safety accidents.

[0007] Furthermore, the first inclined surface gradually inclines toward the bottom plate from the first push plate to the second push plate, and the second inclined surface gradually inclines toward the bottom plate from the second push plate to the first push plate. When the first push plate and the second push plate move toward each other, the inverted ladder member rises; when the first push plate and the second push plate move away from each other, the inverted ladder member falls.

[0008] Furthermore, the first inclined surface gradually inclines toward the bottom plate from the second push plate to the first push plate, and the second inclined surface gradually inclines toward the bottom plate from the first push plate to the second push plate. When the first push plate and the second push plate move away from each other, the inverted ladder member rises; when the first push plate and the second push plate move toward each other, the inverted ladder member falls. When the adjustment mechanism fails, the inverted ladder member falls downward, and the first push plate and the second push plate move toward each other until the first push plate and the second push plate cannot move, and the first push plate and the second push plate restrict the further falling of the inverted ladder member, further avoiding safety accidents.

[0009] Furthermore, the adjustment mechanism includes two groups of pushing mechanisms, both of which are arranged on the bottom plate and are connected to the first push plate and the second push plate respectively. The two groups of pushing mechanisms drive the first push plate and the second push plate to move toward or away from each other, thereby adjusting the height of the inverted ladder.

[0010] Further, the pushing mechanism includes a first limit plate, a second limit plate, a threaded rod, a slider and a connecting rod. The first limit plate and the second limit plate are both arranged on the bottom plate. The two ends of the threaded rod are respectively connected to the first limit plate and the second limit plate for rotation. The slider is threadedly connected to the threaded rod, the slider abuts against the bottom plate, and the two ends of the connecting rod are respectively connected to the slider and the first push plate for rotation, or the two ends of the connecting rod are respectively connected to the slider and the second push plate for rotation. The slider is driven to move by rotating the threaded rod, and the first push plate and the second push plate are driven to move toward or away from each other by the connecting rod to adjust the height of the inverted ladder and support the bridge frame. When the thread on the threaded rod fails, the first push plate and the second push plate will move toward or away from each other, driving the slider to slide on the threaded rod. When the slider slides to the first limit plate or the second limit plate, the first limit plate or the second limit plate prevents the slider from further moving, thereby preventing the inverted ladder from further moving up and down, thereby preventing the bridge frame from falling, supporting stability, and not easily causing safety accidents.

[0011] Furthermore, a linkage assembly is included, the linkage assembly includes a pulley and a synchronous belt, the same end of the two threaded rods is connected to the pulleys respectively, and the two pulleys are connected by the synchronous belt transmission. By setting the linkage assembly, when one threaded rod is rotated, the pulley and the synchronous belt drive the other threaded rod to rotate, so that the height of the inverted ladder is easily adjusted.

[0012] Furthermore, a blocking plate for preventing the first push plate or the second push plate from sliding is provided on the bottom plate. By providing the blocking plate, excessive movement of the first push plate and the second push plate is limited.

[0013] Furthermore, a buffer ring is provided on the bottom plate and between the first push plate and the second push plate. By providing the buffer ring, when the inverted ladder falls and contacts the buffer ring, the movement of the inverted ladder is damped and buffered to prevent the bridge frame from falling quickly.

[0014] Furthermore, it also includes a positive ladder member, the positive ladder member is arranged on the bottom plate, the positive ladder member has a fifth inclined plane and a sixth inclined plane, the fifth inclined plane and the sixth inclined plane are arranged opposite to each other, the first push plate has a seventh inclined plane, the seventh inclined plane is arranged opposite to the third inclined plane, the second push plate has an eighth inclined plane, the eighth inclined plane is arranged opposite to the fourth inclined plane, the fifth inclined plane abuts against the seventh inclined plane, and the sixth inclined plane abuts against the eighth inclined plane. By setting the fifth inclined plane and the sixth inclined plane, while the first inclined plane and the second inclined plane are used to make the inverted ladder member move up and down, the fifth inclined plane and the sixth inclined plane can also make the inverted ladder member move up and down, which can speed up the height adjustment speed and expand the height adjustment range. At the same time, the fifth inclined plane and the sixth inclined plane can also further increase the friction force, further preventing the inverted ladder member from falling quickly.

[0015] Furthermore, the first push plate and the second push plate are both connected to a sliding assembly, and the sliding assembly includes a horizontal sliding plate and a vertical sliding plate, the horizontal sliding plate is connected to the bottom plate, the horizontal sliding plate slides relative to the bottom plate in a first direction, the vertical sliding plate is connected to the horizontal sliding plate, the vertical sliding plate slides relative to the horizontal sliding plate in a second direction, and the vertical sliding plates are respectively connected to the first push plate and the second push plate. By setting the sliding assembly, the horizontal sliding plate is used to slide horizontally on the bottom plate to guide and support the horizontal movement of the first push plate and the second push plate, and the vertical sliding plate is used to slide vertically on the horizontal sliding plate to guide and support the vertical movement of the first push plate and the second push plate, so that the movement of the first push plate and the second push plate on the positive ladder member is more stable.

[0016] Compared with the prior art, the present invention has the following beneficial effects: A bracket for bridge construction of the present invention, when the adjustment mechanism fails, the inverted ladder piece falls downward, the first inclined surface slides relative to the third inclined surface, and the second inclined surface slides relative to the fourth inclined surface, and the sliding friction force of the surface contact prevents the inverted ladder piece from falling downward quickly, thereby preventing the bridge frame from falling quickly and not easily causing safety accidents. A bracket for bridge construction of the present invention drives the slider to move by rotating the threaded rod, and drives the first push plate and the second push plate to move toward or away from each other through the connecting rod, so as to adjust the height of the inverted ladder piece and support the bridge frame. When the threads on the threaded rod fail, the first push plate and the second push plate will move toward or away from each other, driving the slider to slide on the threaded rod. When the slider slides to the first limit plate or the second limit plate, the first limit plate or the second limit plate prevents the slider from further moving, thereby preventing the inverted ladder piece from further moving up and down, thereby preventing the bridge frame from falling, and the support is stable and not easily causing safety accidents. A support for bridge construction of the present invention provides a buffer ring. When the inverted ladder member falls and contacts the buffer ring, the movement of the inverted ladder member is damped and buffered to prevent the bridge frame from falling quickly. A support for bridge construction of the present invention provides a sliding assembly. A horizontal sliding plate is used to slide horizontally on a bottom plate to guide and support the horizontal movement of a first push plate and a second push plate. A vertical sliding plate is used to slide vertically on a horizontal sliding plate to guide and support the vertical movement of the first push plate and the second push plate, thereby making the movement of the first push plate and the second push plate on the positive ladder member more stable.

[0020] Embodiment 1 This embodiment is a first embodiment of a bracket for bridge construction. Figure 1 As shown, it includes a bottom plate 1, a first push plate 2, a second push plate 3, a ladder member 4 and an adjustment mechanism for allowing the first push plate 2 and the second push plate 3 to move relative to each other. The first push plate 2 and the second push plate 3 are arranged opposite to each other, and the first push plate 2 and the second push plate 3 are both slidably connected to the bottom plate 1, and the ladder member 4 is slidably connected to the first push plate 2 and the second push plate 3. Figure 4 As shown, the inverted ladder member 4 is provided with an internal reinforcing rib 403. Improving the strength of the inverted ladder member 4 can stably support the bridge frame and increase the service life of the equipment. Figure 2 As shown, the inverted ladder member 4 has a first inclined surface 401 and a second inclined surface 402, and the first inclined surface 401 and the second inclined surface 402 are arranged opposite to each other. Figure 2 and Figure 3As shown, the first push plate 2 has a third inclined surface 201, the second push plate 3 has a fourth inclined surface 301, the first inclined surface 401 abuts against the third inclined surface 201, and the second inclined surface 402 abuts against the fourth inclined surface 301; Figure 1 As shown, the adjustment mechanism is arranged on the bottom plate 1 and is connected to both the first push plate 2 and the second push plate 3. Figure 2 As shown, a buffer ring 8 is also included, which is arranged on the bottom plate 1 and located between the first push plate 2 and the second push plate 3. A guide rod 11 is also provided, which is vertically arranged on the bottom plate 1. The inverted ladder 4 is slidably connected to the guide rod 11 to guide the vertical sliding of the inverted ladder 4. By providing the buffer ring 8, when the inverted ladder 2 falls and contacts the buffer ring 8, the movement of the inverted ladder 2 is damped and buffered to prevent the bridge frame from falling quickly.

[0021] The working principle of a support for bridge construction in this embodiment is as follows: The adjustment mechanism drives the first push plate 2 and the second push plate 3 to move toward or away from each other, so that the first inclined plane 401 slides with the third inclined plane 201, and the second inclined plane 402 slides with the fourth inclined plane 301, driving the inverted ladder 4 to move up and down, and adjusting the height of the inverted ladder 2. When the adjustment mechanism fails, the inverted ladder 4 falls downward, the first inclined plane 401 slides relatively with the third inclined plane 201, and the second inclined plane 402 slides relatively with the fourth inclined plane 301, and the sliding friction force of the surface contact prevents the inverted ladder 4 from falling downward quickly, thereby preventing the bridge frame from falling quickly and not easily causing safety accidents.

[0022] Embodiment 2 This embodiment proposes a support for bridge construction. Based on the first embodiment, in this embodiment, Figure 2 As shown, the first inclined surface 401 gradually inclines toward the bottom plate 1 from the first push plate 2 to the second push plate 3, and the second inclined surface 402 gradually inclines toward the bottom plate 1 from the second push plate 3 to the first push plate 2. When the first push plate 2 and the second push plate 3 move toward each other, the inverted ladder 2 rises; when the first push plate 2 and the second push plate 3 move away from each other, the inverted ladder 2 falls.

[0023] Embodiment 3 This embodiment proposes a support for bridge construction. On the basis of the first embodiment, in this embodiment, the first inclined surface 401 gradually tilts toward the bottom plate 1 from the second push plate 3 to the first push plate 2, and the second inclined surface 402 gradually tilts toward the bottom plate 1 from the first push plate 2 to the second push plate 3. When the first push plate 2 and the second push plate 3 move away from each other, the inverted ladder 2 rises; when the first push plate 2 and the second push plate 3 move toward each other, the inverted ladder 2 falls. When the adjustment mechanism fails, the inverted ladder 4 falls downward, and the first push plate 2 and the second push plate 3 move toward each other until the first push plate 2 and the second push plate 3 cannot move. The first push plate 2 and the second push plate 3 restrict the further falling of the inverted ladder 4 to further avoid causing safety accidents.

[0024] Embodiment 4 This embodiment proposes a support for bridge construction. Based on the first embodiment, in this embodiment, Figure 1 As shown, the adjustment mechanism includes two sets of pushing mechanisms 5, both of which are arranged on the bottom plate 1, and the two sets of pushing mechanisms 5 are respectively connected to the first push plate 2 and the second push plate 3. The two sets of pushing mechanisms 5 drive the first push plate 2 and the second push plate 3 to move toward or away from each other, thereby adjusting the height of the inverted ladder 4.

[0025] The pushing mechanism 5 includes a first limiting plate 501, a second limiting plate 502, a threaded rod 503, a slider 504 and a connecting rod 505. The first limiting plate 501 and the second limiting plate 502 are both arranged on the bottom plate 1. The two ends of the threaded rod 503 are respectively rotatably connected with the first limiting plate 501 and the second limiting plate 502. The slider 504 is threadedly connected with the threaded rod 503. The slider 504 abuts against the bottom plate 1. The two ends of the connecting rod 505 are respectively rotatably connected with the slider 504 and the first push plate 2, or the two ends of the connecting rod 505 are respectively rotatably connected with the slider 504 and the second push plate 3. The slider 504 is driven to move by rotating the threaded rod 503, and the first push plate 2 and the second push plate 3 are driven to move toward or away from each other by the connecting rod 505, so as to adjust the height of the inverted ladder 4 and support the bridge frame. When the threads on the threaded rod 503 fail, the first push plate 2 and the second push plate 3 will move toward or away from each other, driving the slider 504 to slide on the threaded rod 503. When the slider 504 slides to the first limit plate 501 or the second limit plate 502, the first limit plate 501 or the second limit plate 502 prevents the slider 504 from further moving, thereby preventing the inverted ladder 4 from further moving up and down, thereby preventing the bridge frame from falling, providing stable support and not easily causing safety accidents.

[0026] like Figure 4As shown, the embodiment also includes a linkage assembly 6, which includes a pulley 601 and a synchronous belt 602. The same end of the two threaded rods 503 is respectively connected to the pulley 601, and the two pulleys 601 are connected through the synchronous belt 602. By setting the linkage assembly 6, when one threaded rod 503 is rotated, the pulley 601 and the synchronous belt 602 drive the other threaded rod 503 to rotate, so that the height of the inverted ladder 2 can be adjusted easily.

[0027] The linkage assembly 10 further includes two pressure shaft wheels 103. In this embodiment, the two pressure shaft wheels 103 are vertically distributed and are both arranged on the bottom plate 1. The distance between the two pressure shaft wheels 103 is smaller than the diameter of the pulley 101, and the synchronous belt 102 is located between the two pressure shaft wheels 103. By providing the pressure shaft wheels 103, the synchronous belt 102 is restricted to prevent the synchronous belt 102 from falling off the pulley 101.

[0028] Embodiment 5 This embodiment proposes a support for bridge construction. Based on any one of the first to fourth embodiments, in this embodiment, Figure 2 As shown, the embodiment also includes a positive ladder member 9, which is arranged on the bottom plate 1. The positive ladder member 9 has a fifth inclined plane 901 and a sixth inclined plane 902, which are arranged opposite to each other. The first push plate 2 has a seventh inclined plane 202, which is arranged opposite to the third inclined plane 201. The second push plate 3 has an eighth inclined plane 302, which is arranged opposite to the fourth inclined plane 301. The fifth inclined plane 901 abuts against the seventh inclined plane 202, and the sixth inclined plane 902 abuts against the eighth inclined plane 302. By providing the fifth inclined plane 901 and the sixth inclined plane 902, while the first inclined plane 401 and the second inclined plane 402 are used to make the inverted ladder member 2 move up and down, the fifth inclined plane 901 and the sixth inclined plane 902 can also make the inverted ladder member 2 move up and down, thereby accelerating the height adjustment speed and expanding the height adjustment range. At the same time, the fifth inclined surface 901 and the sixth inclined surface 902 can further increase the friction force, thereby further preventing the inverted ladder member 2 from falling quickly.

[0029] like Figure 3As shown, the first push plate 2 and the second push plate 3 are both connected with a sliding assembly 10, and the sliding assembly 10 includes a horizontal sliding plate 101 and a vertical sliding plate 102. The horizontal sliding plate 101 is connected to the bottom plate 1, and the horizontal sliding plate 101 slides relative to the bottom plate 1 along a first direction. The vertical sliding plate 102 is connected to the horizontal sliding plate 101, and the vertical sliding plate 102 slides relative to the horizontal sliding plate 101 along a second direction. The vertical sliding plate 102 is respectively connected to the first push plate 2 and the second push plate 3, and the first direction is perpendicular to the second direction, the first direction is the horizontal direction, and the second direction is the vertical direction. By setting the sliding assembly 10, the horizontal sliding plate 101 is used to slide horizontally on the bottom plate 1 to guide and support the horizontal movement of the first push plate 2 and the second push plate 3, and the vertical sliding plate 102 is used to slide vertically on the horizontal sliding plate 101 to guide and support the vertical movement of the first push plate 2 and the second push plate 3, so that the movement of the first push plate 2 and the second push plate 3 on the positive ladder member 9 is more stable. At the same time, a side cutting triangle 12 is provided, which is located at the bottom of the first push plate 2 and the second push plate 3. The side cutting triangle 12 is slidably connected to the vertical sliding plate 102 and the bottom plate 1 respectively to prevent the first push plate 2 and the second push plate 3 from turning over or deflecting during movement. At the same time, by increasing the contact surface, anti-slip grooves are provided on the inclined surface, which can also further increase the sliding friction and prevent the inverted ladder 4 from falling quickly.
