Description

Technical Field

[0001] The invention relates to the field of bridge bearings, and in particular to a quick-changing device for bridge bearings. Background Art

[0002] As a key component of the bridge structure, the bridge bearing is like the "joint" of the bridge. It can reasonably transfer the load of the bridge superstructure to the substructure to ensure that the bridge structure is evenly stressed. Without good bearings, the load of the bridge superstructure may not be effectively dispersed, which will cause excessive stress on the piers and abutments, leading to structural damage.

[0003] At present, bridge bearings have developed into many types, including: plate bearings, pot bearings, spherical bearings, etc. However, no matter what type of bearing, it will age or corrode after long-term use and needs to be replaced. The most widely used is the pot bearing, which is usually used on urban viaducts or highway bridges. The pot bearing generally also includes an upper steel plate installed on the lower side of the bridge deck. The pot bearing is installed under the upper steel plate and above the top beam to support the bridge deck. When replacing, the pot bearing needs to be removed, and then the upper steel plate and the pad stone at the bottom of the pot bearing are removed, and a new upper steel plate is reinstalled, and then the new pot bearing is installed on the new upper steel plate, and the anchor bars are laid between the base of the new pot bearing and the top beam, and the connection is re-grouted.

[0004] However, it is inconvenient to find the correct position when installing the new upper steel plate and installing the new pot-type bearing between the upper steel plate. Moreover, since the new upper steel plate is pasted to the lower side of the bridge deck from bottom to top with structural adhesive, there is a risk of it falling during pasting and it needs to be supported. The existing replacement method supports it by setting up a bracket, which is extremely inconvenient and time-consuming. It is also inconvenient to accurately install the new pot-type bearing on the corresponding position of the pasted upper steel plate, resulting in the need to install the upper steel plate according to the measured position, and the position needs to be measured when installing the pot-type bearing, resulting in low operating efficiency and cumbersome and time-consuming replacement.

[0005] Even though other types of bridge bearings may not require removal of the upper steel plate when replacing, the bearings still need to be aligned with the upper steel plate when replacing the bearings, and the existing alignment methods generally require cumbersome measurements, which restricts the replacement speed of the bearings. Therefore, a quick replacement device for bridge bearings is proposed. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: See also Figure 1-11 The present invention provides a technical solution: a quick replacement device for a bridge support, comprising a base 1, a motor 2 is mounted on the base 1, and a cross shaft 4 is connected to the output end of the motor 2, a ring 5 is slidably sleeved on the cross shaft 4, a support plate 9 is connected to the ring 5, and both ends of the support plate 9 are slidably sleeved with a frame 10, such as Figure 1 and 3 As shown, the frames 10 on both sides are symmetrically slidably sleeved on both ends of the support plate 9; A sliding rod seat 11 is slidably sleeved on the frame 10, and a supporting frame 12 for supporting the upper steel plate 431 is connected to the sliding rod seat 11. A slider 25 is slidably connected to the frame 10, and an arc-shaped clamping frame 31 for clamping the bridge basin support 432 is slidably connected to the slider 25. A driving component is provided on the frame 10, and the driving component is used to drive the supporting frames 12 on both sides to approach each other, or drive the arc-shaped clamping frames 31 on both sides to approach each other. The frame 10 is also slidably connected with a clamping plate 22, and the ring 5 is provided with a drive switching assembly, which is used to switch whether the motor 2 drives the frame 10 to rotate through the cross-axis rod 4 or drives the clamping plate 22 to slide through the cross-axis rod 4. The frame 10 is provided with an alignment assembly, which is used to align the arc-shaped clamping frame 31 with the center line of the upper steel plate 431 during clamping.

[0032] like Fig.10 and 11 As shown, the top beam 433 is located on the pier 434 , and the bridge deck of the bridge is located on the top beam 433 .

[0033] Furthermore, the slide rod seat 11 is slidably connected to the frame 10, and a spring 13 is sleeved on the surface of the outer side of the frame 10, and the two ends of the spring 13 are respectively connected to the frame 10 and the slide rod seat 11, as shown in FIG. Figure 1 and 5 As shown, the slide rod seat 11 can slide through the frame 10, and the setting of the spring 13 can provide elastic force for the slide rod seat 11 to drive the supporting frame 12 to slide away from the frame 10, so that in the absence of external force, the slide rod seat 11 can slide away from the frame 10 under the action of the spring 13 until it reaches a limit state.

[0034] Furthermore, the driving assembly includes a pull plate 15, a telescopic member 16, a push frame 17, a top plate 18, a slide bar seat 29, a slide plate 30, a spring 22, and an inclined block 33. The pull plate 15 is slidably arranged on both sides of the upper end of the frame 10, the telescopic member 16 is installed on the frame 10, the push frame 17 is connected to the telescopic member 16, and cooperates with the pull plate 15. A rotating plate 19 is rotatably connected between the adjacent slide bar seats 11 and the pull plate 15 through a spring hinge. The slide bar seat 29 is connected to the slider 25, and the slide plate 30 is slidably sleeved on the outer side of the slide bar seat 29. The arc-shaped clamping frame 31 is connected to the slide plate 30. The inclined block 33 is connected to the arc-shaped clamping frame 31. The top plate 18 is connected to the push frame 17 and is slidably connected to the surface of the inclined block 33. The outer side of the slide bar seat 29 is sleeved with a spring 22, and the two ends of the spring 22 are respectively connected to the slide bar seat 29 and the slide plate 30. Figure 1 , 6As shown in FIG. 7 , the contraction of the telescopic member 16 in the initial state can drive the push frames 17 on the two side frames 10 to approach each other, and drive the pull plates 15 on the two side frames 10 to approach each other, and pull the rotating plate 19 to rotate, so as to drive the slide rod seats 11 on both sides to drive the supporting frames 12 to approach each other to support and clamp the upper steel plate 431. When the telescopic member 16 is extended from the initial state, the top plate 18 can be brought into contact with the inclined block 33 and slide in close proximity, thereby driving the slide plates 30 and the arc-shaped clamping frames 31 on both sides to approach each other, and compress the spring 2 32 to clamp the bridge basin support 432.

[0035] Furthermore, guide slide bars 14 are connected to both sides of the frame 10, and each pull plate 15 is slidably sleeved on the outer side of the guide slide bar 14 on each side. A support plate 43 for supporting the bridge basin support 432 is also connected to the slide bar seat 29. Figure 6 As shown, the setting of the guide slide rod 14 can stabilize the sliding of the pull plate 15, and the setting of the support plate 43 can provide certain support before the arc-shaped clamping frame 31 clamps the bridge basin support 432, so as to facilitate the subsequent clamping operation.

[0036] Further, the alignment assembly includes a horizontal plate 21, a telescopic rod 26, and a hinge seat 27. The horizontal plate 21 is connected to the bottom of the clamping plate 22 and is slidably connected to the frame 10. The slider 25 is connected to the telescopic rod 26, and the other end of the telescopic rod 26 is connected to the hinge seat 27. The two ends of the hinge seat 27 are respectively connected to the frame 10 and the horizontal plate 21 through elastic hinges and are rotatably connected to the rotating plate 28. Figure 6As shown, after the supporting frames 12 on both sides are close to each other and clamp the two side edges of the upper steel plate 431, the clamping plate 22 can be driven to approach the upper steel plate 431 to ensure that the upper steel plate 431 can be limited to the area surrounded by the supporting frames 12 on both sides and the clamping plates 22. At the same time, the sliding of the clamping plates 22 can drive the rotating plate 28 to rotate, thereby pushing the hinge seat 27 to slide, so that the hinge seat 27 rotatably connected to the spring hinge of the rotating plate 28 can always be in the midpoint position of the rotational connection between the rotating plates 28 on both sides and the frame 10 and the cross plate 21 respectively. It is only necessary to control the rotational connection between the rotating plate 28 on one side and the frame 10 to correspond to the inner wall of the side of the supporting frame 12 close to the cross shaft rod 4, so as to ensure that the hinge seat 27 is in the limited upper position at this time. The midline position of the steel plate 431, and the sliding of the hinged seat 27 will also slide together with the slider 25 through the telescopic rod 26. Since the rotation of the rotating plate 28 will change the distance between the hinged seat 27 and the slider 25, the telescopic rod 26 can adapt to the change of the distance by telescoping, so that the arc-shaped clamping frame 31 on the slider 25 will also be at the midline of the limited upper steel plate 431. At this time, the clamping plates 22 on the two side frames 10 are adjusted synchronously, and then the upper steel plate 431 can be limited and supported by the supporting frame 12 in one side frame 10, and the bridge basin support 432 can be clamped by the arc-shaped clamping frame 31 in the other side frame 10. At the same time, it can also ensure that the midline of the bridge basin support 432 corresponds to the upper steel plate 431 on the other side, that is, Fig.11 As shown, during the specific installation, the upper steel plate 431 is supported on the upper limit position of the support frame 12 on one side, and the arc-shaped clamping frame 31 on the other side clamps the bridge pot support 432. Then, the upper steel plate 431 is installed first, and then the bridge pot support 432 is installed by rotation and adjustment, so that direct alignment installation can be achieved.

[0037] Further, the frame 10 is provided with a slideway 24, the slider 25 passes through the limit slide in the slideway 24, and the telescopic rod 26 is connected to the outside of the frame 10, and an arc-shaped clamping frame 31 is provided on the inside, the frame 10 is connected to the guide plate 20, and the cross plate 21 is slidably sleeved on the outside of the guide plate 20, such as Figure 1 and 6 As shown, the provision of the slideway 24 enables the slider 25 to slide stably, and the provision of the guide plate 20 can also ensure that the cross plate 21 drives the clamping plate 22 to slide stably.

[0038] Further, the drive switching assembly includes a disc 3, a reel 6, a plug rod 7, a socket 8, a pull rope 23, an annular slide rail 35, a swivel 36, a slide seat 38, and a telescopic member 39. The disc 3 is connected between the output end of the motor 2 and the cross shaft 4, the reel 6 is connected below the ring 5, the plug rod 7 array is connected to the lower side of the reel 6, the socket 8 array is opened on the disc 3, and is inserted in conjunction with the plug rod 7, and the pull rope 23 is connected between the two sides of the reel 6 and the clamping plates 22 on both sides, such as Figure 3 and 8 As shown, when the insertion rod 7 and the insertion hole 8 are not inserted, the operation of the motor 2 will drive the reel 6 to synchronously pull the clamping plates 22 on both sides, so as to limit the other two side surfaces of the upper steel plate 431 supported on the support frame 12, so as to ensure that the upper steel plate 431 is gradually limited to the area surrounded by the support frame 12 and the clamping plates 22, and when the insertion rod 7 and the insertion hole 8 are inserted, the operation of the motor 2 will drive the rotation of the entire support plate 9, and then drive the frame 10 slidably sleeved thereon on both sides to rotate; The annular slide rail 35 is connected to the upper end of the base 1, the swivel 36 is rotatably connected in the annular slide rail 35, and the two sides of the swivel 36 are parallelly installed with slide rails 37, the two ends of the slide seat 38 are slidably connected in the slide rails 37, the telescopic member 39 is connected to the slide seat 38, and the frame 10 is connected to the telescopic member 39. Figure 3 and 8 As shown, the telescopic part 2 39 can be used to adjust the height of the two side frames 10 and the support plate 9, and then adjust whether the insertion rod 7 and the socket 8 are inserted and matched. The sliding of the slide 38 in the slide rail 37 can synchronously adjust the distance between the two side slides 38 and the frame 10 connected to the slide 38 by the telescopic part 2 39 to adapt to the adjustment of different installation positions of the upper steel plate 431 and the bridge basin support 432. The damping rotation sleeve of the swivel 36 and the annular slide rail 35 can stabilize the support plate 9 when it is driven to rotate. The depth of the support frame 12 is very shallow. When the upper steel plate 431 is limited therein, it will be higher than the upper end surface of the support frame 12 to facilitate installation. At the same time, the distance between the arc-shaped clamping frame 31 and the support frame 12 is very small, so that when the arc-shaped clamping frame 31 clamps the bridge basin support 432, its upper end can also be on the upper end surface of the support frame 12 to facilitate installation.

[0039] Further, the ring 5 and the support plate 9 are connected by damping rotation, the swivel 36 and the annular slide rail 35 are connected by damping rotation, and the damping force between the ring 5 and the support plate 9 is less than the damping force between the swivel 36 and the annular slide rail 35. Figure 8 As shown, such an arrangement prevents the driving of the motor 2 from driving the support plate 9 to rotate when the insertion rod 7 and the insertion hole 8 are not properly inserted.

[0040] Furthermore, the inner wall of the support frame 12 and the surface of the clamping plate 22 are both rotatably mounted with balls 34. Figure 6 As shown, the provision of the ball 34 makes it convenient for the supporting frame 12 to be withdrawn from under the upper steel plate 431 by directly contracting and descending the telescopic member 2 39 after the upper steel plate 431 is supported and pasted for installation, thereby reducing friction and allowing the upper steel plate 431 to maintain its installation state with the lower side of the bridge deck.

[0041] Furthermore, both sides of the base 1 are rotatably sleeved with screw rods 40, and the sides of the screw rods 40 on both sides close to each other are rotatably connected with a limit plate 41 that slides in contact with the lower end of the base 1, and the limit plate 41 is connected to a guide rod 42, and the guide rod 42 is slidably sleeved with the base 1, such as Figure 2 As shown, the base 1 can be conveniently mounted on the top beam 433 by rotating the screw rod 40 to drive the limiting plate 41 to slide.

[0042] Working principle: by controlling the telescopic member 16 on one side of the frame 10 to contract, the pull plate 15 is pulled to drive the rotating plate 19 to rotate, so that the two supporting frames 12 in the frame 10 are close to each other, and then the upper steel plate 431 is supported and centrally clamped. At the same time, the motor 2 can also drive the reel 6 on the ring 5 to rotate and pull the pull ropes 23 on both sides to reel in. At this time, the insertion rod 7 and the insertion hole 8 are in a state of not being matched and inserted, so as to drive the clamping plates 22 on both sides to approach each other, so that the single-sided frame 10 can limit the four sides of the upper steel plate 431 through the supporting frame 12 and the clamping plate 22, and it is convenient to clamp the upper steel plates of different sizes in the center, thereby improving the versatility. In the above process, since the supporting frames 12 in the frame body 10 on one side are in a state of being close to each other, while the other side is stationary, but the pull ropes 23 on both sides are synchronously rolled up, the horizontal plates 21 on the frame bodies 10 on both sides are close to each other, and at the same time, the rotating plates 28 on both sides rotate synchronously, which will also synchronously drive the sliders 25 on both sides to adjust synchronously with the arc-shaped clamping frames 31, and symmetrically be at the position of the midline of the clamped upper steel plate 431. At this time, the telescopic member 16 on the frame body 10 on the other side that does not clamp the upper steel plate 431 is controlled to extend, so that the two arc-shaped clamping frames 31 in the frame body 10 on the other side can be driven to be close to each other, and the bridge basin support 432 is clamped. In the process of installing and pasting the upper steel plate 431, the supporting frame 12 can also support the upper steel plate, avoiding the need to set up a bracket, improving the convenience and efficiency of installation, and having universality, and can be applicable to the replacement and installation of bridge supports of various sizes. The slide seats 38 on both sides are controlled to slide synchronously and symmetrically in the slide rails 37 on both sides of the motor 2, and the spacing between the frames 10 on both sides is adjusted to adjust the steel plate 431 clamped on one of the frames 10 and the position to be installed on the top beam 433 accordingly, so that the focus of the installation position is on the circumference of the rotation of the two frames 10, and then the telescopic member 2 39 is used to adjust the height, so that the insertion rod 7 and the insertion hole 8 are matched and inserted, and then the motor 2 drives the two frames 10 to move Fig.11The state that is perpendicular to the top beam 433 is rotated 90° to a parallel state. At this time, the upper steel plate 431 will be rotated to the corresponding position that needs to be installed between the top beam 433 and the bridge deck, and the upper steel plate 431 is pushed up and installed on the lower side of the bridge deck by extending the telescopic member 39 again. After the installation is completed, the supporting frame 12 is withdrawn from the lower side, and the two side frames 10 are rotated 180° again, and the bridge basin support 432 clamped on the other side is rotated to the bottom of the upper steel plate 431, and it is installed in coordination with the upper steel plate 431 to ensure efficient and fast installation and alignment, which further improves the installation speed.

[0043] Even if the upper steel plate 431 may not be removed when the bridge bearing is replaced, the supporting frame 12 and the clamping plate 22 can be clamped with the upper steel plate 431 that has not been removed, so as to help the arc-shaped clamping frame 31 on the other side frame 10 to be centered with it, so that after clamping the bridge basin bearing 432, the bridge basin bearing 432 can be installed directly by rotating the frames 10 on both sides to exchange their positions.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
