Description

Technical Field

[0001] This utility model relates to the technical field of support devices, and in particular to an anti-overturning support device for railway bridge construction. Background Technology

[0002] Railway bridges are structures built to cross rivers, lakes, straits, valleys or other obstacles, as well as to achieve grade separation between railway lines or roads. To reduce the land area occupied, shorten the construction period, reduce the construction difficulty, and facilitate later maintenance, single-column pier bridges are often used during construction.

[0003] Existing single-column pier bridges use a single support in the transverse direction, which provides weak lateral restraint on the main beam. Under heavy eccentric loads or earthquakes, the support may come loose, causing a major accident of lateral overturning of the main beam. Therefore, anti-overturning reinforcement is often carried out on existing single-column pier bridges to reduce the risk of overturning damage and extend the service life of the bridge.

[0004] In related technologies, clamp structures are used in conjunction with support seats to reinforce single-column pier bridges against overturning, transforming single-point support into multi-point support, which greatly reduces the risk of railway bridges overturning. However, clamp installation requires operators to lift the clamps and construction workers to manually align the two clamps for installation. During construction, at least two workers are needed to align the holes on the clamps, and then other workers use fasteners to fix the clamps in place. The assembly process is relatively cumbersome and has certain limitations. Utility Model Content

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] This utility model adopts a spring-block linkage structure. When the clamp is inserted towards the pier, the inclined surface of the block is automatically pushed by the edge of the pier and retracted into the frame. After the block contacts the concave hole, the spring is released to achieve instantaneous locking. The clamp is initially limited by the contact between one end of the block and the concave hole, which facilitates the installation of the clamp by the operator. Initially, only one concave hole needs to be opened on the pier, which reduces the cost. The entire installation process does not require multiple operators to repeatedly align, saving manpower and improving installation efficiency. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] Given that current technologies use clamp structures in conjunction with support seats to reinforce single-column pier bridges against overturning, transforming single-point support into multi-point support, which greatly reduces the risk of railway bridges overturning, the clamps are cumbersome to assemble and inconvenient to use.

[0044] like Figure 1-5 As shown, this utility model embodiment provides an anti-overturning support device for railway bridge construction, including: a pier 1, on which a bridge 2 is installed, and the top of the pier 1 has a recessed hole; a first clamp 3 and a second clamp 4, which are installed on the outside of the pier 1 by bolts 8, and the top of the pier 1, the first clamp 3 and the second clamp 4 are all supported by support blocks 5 set on the top; a rubber sheet 9 is set on the inside of the first clamp 3 and the second clamp 4; a limit component 6 is set on the first clamp 3 and the second clamp 4; the limit component 6 It includes: a frame 61, fixedly connected to the inside of clamp 3 and clamp 4; a rod 62, slidably connected to the inside of the frame 61; a plug 63, fixedly connected to the bottom of the rod 62, extending to the bottom of the frame 61; a first groove 64, formed inside the frame 61, and the plug 63 moves up and down inside the first groove 64; a spring 65, sleeved on the outside of the rod 62; a second groove 66, formed inside the frame 61, for accommodating the spring 65; and a seat 67, fixedly connected to the top of the frame 61.

[0045] When reinforcement of pier 1 is required, the operator uses hoisting equipment (existing technology, not shown in the figure) to lift clamp 3 and clamp 4, then aligns them with the holes on clamp 3 and clamp 4 and tightens them with bolts 8 to secure pier 1. In addition, the rubber skin 9 inside clamp 3 and clamp 4 increases the friction between the clamp and pier 1, preventing the clamp from falling off. After clamp 3 and clamp 4 are installed, the support blocks 5 set on clamp 3 and clamp 4 can work with pier 1 to provide multi-point support for bridge 2, thereby reducing the risk of bridge 2 overturning.

[0046] During the installation of clamp 3 and clamp 4, clamp 3 is first hoisted. The operator makes minor adjustments to align multiple inserts 63 with the recessed holes on pier 1. Then, clamp 3 is pushed towards the center of pier 1. During this process, the inclined surface of one side of insert 63 is pressed against the edge of pier 1 and pushed upwards, causing insert 63 to retract into the first groove 64 and press upwards against the bottom of spring 65. Because the top of the second groove 66 presses against spring 65, hindering the upward movement of the top of spring 65, spring 65 is gradually compressed. The rod 62... At this time, the insert 63 also moves upwards. The height of the groove 611 is greater than the height of the insert 63. Therefore, when the insert 63 retracts into the frame 61, the top of the rod 62 will not come out of the groove 611, thus ensuring the normal use of the spring 65 and preventing the top of the rod 62 from sliding out of the groove 611 and rotating to the top of the frame 61, causing the spring 65 to fail to release properly. When the insert 63 moves to the position of the recessed hole on the pier 1, the insert 63 is pushed out of the frame 61 by the spring 65 and inserted into the recessed hole, through the side of the insert 63 without the bevel. The contact with the sidewall of the concave hole provides initial positioning of clamp 3. Then, clamp 4 is installed on one side of clamp 3 following the same steps. Clamps 3 and 4 are then fastened together with bolts 8, completing the installation. The entire process requires no repeated alignment or temporary support frames for fixing clamps 3 and 4, allowing them to be installed on the outside of pier 1. This saves labor and reduces installation time. When inspecting clamps 3 and 4, the operator first... Insert the rod into the groove 611, hold the top of the rod 62 and pull it upward. After pulling the top of the rod 62 out of the groove 611, rotate the top of the rod 62 to the seat 67, and then release. The rod 62 moves downward under the action of the spring 65 and is placed on the top of the seat 67. Since the height of the groove 611 is greater than the height of the insert 63, the insert 63 will inevitably move out of the recess after the rod 62 is pulled above the groove 611. After performing the above operation on all the rods 62, loosen the bolt 8 and disassemble the first clamp 3 and the second clamp 4.

[0047] In some embodiments, auxiliary components 7 are provided on the first clamp 3 and the second clamp 4. The auxiliary components 7 include: a plug rod 71, which is fixedly connected to one side of the first clamp 3; and a plug hole 72, which is opened on one side of the second clamp 4. The size and shape of the plug hole 72 are matched with the plug rod 71, so that after the first clamp 3 or the second clamp 4 is initially positioned, the installation of the other clamp can be indicated by the plug rod 71 or the plug hole 72 (for example, after the first clamp 3 is initially positioned, the plug hole 72 on the second clamp 4 can be aligned with the plug rod 71 on the first clamp 3 and inserted, so as to facilitate the alignment of the first clamp 3 and the second clamp 4).

[0048] In some embodiments, the insertion rod 71 and the insertion hole 72 are a set, and multiple sets are provided on the first clamp 3 and the second clamp 4. The multiple sets of insertion rods 71 ​​and insertion holes 72 work together to serve as an installation indicator, and can also enhance the stability of the support between the two clamps by means of the insertion rod 71 when the bolt 8 is not tightened.

[0049] In some embodiments, one side of the insert 63 is provided with an inclined surface, so that when the first clamp 3 or the second clamp 4 is pushed toward the pier 1, the edge of the pier 1 can press the inclined surface of the insert 63, thereby pushing the insert 63 upward and retracting it into the interior of the frame 61, preventing the insert 63 from blocking the movement of the frame 61.

[0050] In some embodiments, the first groove 64 is formed at the bottom of the second groove 66, and the diameter of the second groove 66 is smaller than that of the first groove 64. The sliding of the insert 63 is limited by the first groove 64 to prevent excessive force from being applied when the rod 62 is pulled upward, which could damage the spring 65.

[0051] In some embodiments, the top of the frame 61 has a groove 611, the top of the rod 62 is placed in the groove 611, and the length of the groove 611 is greater than the axial length of the top of the rod 62, so that the operator can put his hand into the groove 611 and pry up the top of the rod 62.

[0052] In some embodiments, the top of the seat 67 is curved, and the supporting force of the top of the seat 67 on the top of the rod 62, combined with the tension of the spring 65 on the rod 62, enhances the fixing effect of the rod 62.

[0053] In some embodiments, the rod 62 and the insert 63 are a set, and multiple sets are provided on the frame 61 to enhance the stability of the initial fixing of the first clamp 3 or the second clamp 4.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
