Description

Technical Field

[0001] This utility model relates to the field of bridge support technology, specifically to a bridge bearing replacement frame. Background Technology

[0002] Bridge bearings are key components connecting the superstructure (beams, slabs) and substructure (piers) of a bridge, bearing the responsibility of transferring loads and accommodating deformation. With increasing service life, bearings may experience aging, deformation, cracking, or excessive displacement, requiring timely replacement to ensure bridge safety.

[0003] In existing technologies, when replacing bridge bearings, it is usually necessary to install multiple load-bearing frames on the side of the bridge base, and then use jacks to lift the bridge to detach it from the bearings so that the bearings can be removed for replacement. However, the load-bearing frames need to be distributed and installed on the side of the bearings, and the adjacent load-bearing frames do not interfere with each other. The independently distributed load-bearing frames lack lateral connections. If the load on a certain bearing area suddenly increases (such as due to jacking deviation), it may cause local load-bearing frames to be overloaded and deformed. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a bridge bearing replacement frame to solve the problem mentioned in the background art that bridge bearing frames need to be installed in a distributed manner, and that independently distributed bearing frames lack lateral connections. If the load on a certain bearing area suddenly increases, it may lead to overload deformation of the local bearing frame.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A bridge bearing replacement frame, comprising:

[0007] A base, wherein a bridge plate is disposed on top of the base, characterized in that it further includes:

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] Example 1:

[0048] like Figures 1 to 6 As shown, this utility model provides a bridge bearing replacement frame, including: a base 1, a bridge plate 101 is arranged above the base 1, and multiple lifting structures arranged on the base 1 for lifting the bridge plate 101.

[0049] The lifting structure includes a load-bearing frame 2 that can be detachably installed on one side of the base 1, a jack 201 arranged above the load-bearing frame 2, the output end of the jack 201 contacting the bottom of the bridge plate 101, and two reinforcing inclined plates 202 arranged on the load-bearing frame 2. During installation, multiple load-bearing frames 2 can be fixed to the side of the base 1 with bolts. By opening the jack 201 on the load-bearing frame 2, its output end can lift the bridge plate 101, making it convenient to replace the support between the base 1 and the bridge plate 101.

[0050] Example 2:

[0051] Based on Example 1, in order to improve the connection stability of the load-bearing frame 2, a connection structure that can be connected into a whole is arranged on the two adjacent lifting structures.

[0052] The connecting structure includes two connecting sleeves 3 movably fitted onto the corresponding two reinforcing inclined plates 202, several mounting screws 301 movably installed inside the corresponding reinforcing inclined plates 202 and connecting sleeves 3, two nuts 302 threaded onto both ends of the mounting screws 301, a spacing adjustment component arranged on the two connecting sleeves 3 for adjusting the distance between the two connecting sleeves 3, and a sleeve groove adapted to the reinforcing inclined plates 202 on the connecting sleeves 3. The two connecting sleeves 3 can be respectively fitted onto the reinforcing inclined plates 202 of the two load-bearing frames 2. After the mounting screws 301 are passed through the connecting sleeves 3 and the reinforcing inclined plates 202 and fixed with the nuts 302, the adjacent load-bearing frames 2 can form a whole after the connection is completed, improving their stability.

[0053] Specifically, the spacing adjustment assembly includes two fixing screws 303 respectively arranged on the side of the two connecting sleeve plates 3 that are close to each other, and a bidirectional threaded sleeve 304 threaded on the two fixing screws 303. Rotating the bidirectional threaded sleeve 304 can drive the two fixing screws 303 to move simultaneously in a direction that is close to or far from each other, so as to adjust the distance between the two connecting sleeve plates 3 according to the spacing between the two adjacent load-bearing frames 2.

[0054] Specifically, the spacing adjustment component also includes a sliding sleeve rod 305 and a guide rod 306 respectively arranged on the side of the two connecting sleeve plates 3 that are close to each other. The sliding sleeve rod 305 is slidably sleeved on the guide rod 306. When the connecting sleeve plate 3 moves, it will drive the corresponding guide rod 306 to slide inside the sliding sleeve rod 305. The sliding sleeve rod 305 and the guide rod 306 can limit the movement direction of the two connecting sleeve plates 3, and at the same time prevent the connecting sleeve plate 3 from rotating along with the bidirectional threaded sleeve rod 304.

[0055] Example 3:

[0056] Based on Embodiment 2, in order to provide additional support for the load-bearing frame 2, a support structure for providing support for the lifting structure is arranged on the connection structure.

[0057] The support structure includes a support rod 4 rotatably mounted on one side of the connecting sleeve plate 3, a movable sleeve rod 401 slidably sleeved on the support rod 4, a connecting seat 402 rotatably mounted on one end of the movable sleeve rod 401, several fixed insert rods 403 movably mounted inside the connecting seat 402, and a telescopic adjustment assembly arranged on the support rod 4 to drive the support rod 4 to slide and extend within the movable sleeve rod 401. The connecting seat 402 can be brought into contact with the ground, and then the fixed insert rods 403 can be passed through the connecting seat 402 and inserted into the ground to fix one end of the movable sleeve rod 401. The support rod 4 and the movable sleeve rod 401 provide lateral support for the connecting sleeve plate 3 and the load-bearing frame 2, further improving their stability.

[0058] Specifically, the telescopic adjustment assembly includes a threaded adjustment sleeve 404 rotatably sleeved on the movable sleeve rod 401, and a threaded hole 405 opened inside the threaded adjustment sleeve 404. The support rod 4 is threadedly installed inside the threaded hole 405. When the movable sleeve rod 401 is held and the threaded adjustment sleeve 404 is rotated, the threaded adjustment sleeve 404 can move through the threaded engagement between the threaded hole 405 and the support rod 4, so that the threaded adjustment sleeve 404 can drive the movable sleeve rod 401 to slide on the support rod 4.

[0059] Specifically, the telescopic adjustment assembly also includes a limiting ring 406 fixedly sleeved on the movable sleeve rod 401 to limit the position of the threaded adjustment sleeve 404 when it rotates. The limiting ring 406 is rotatably installed inside the threaded adjustment sleeve 404. When the threaded adjustment sleeve 404 rotates, it can rotate on the limiting ring 406. The setting of the limiting ring 406 can prevent the threaded adjustment sleeve 404 from detaching from the movable sleeve rod 401.

[0060] Working principle:

[0061] During installation, multiple load-bearing frames 2 can be fixed to the side of the base 1 with bolts. Then, the bidirectional threaded sleeve 304 can be rotated. The bidirectional threaded sleeve 304 has two sets of threads facing opposite directions, and these threads are compatible with the fixing screws 303. Therefore, when the bidirectional threaded sleeve 304 rotates, it can drive the two fixing screws 303 to move simultaneously in a direction closer or further apart, so as to adjust the distance between the two connecting sleeves 3 according to the distance between two adjacent load-bearing frames 2. When the connecting sleeves 3 move... This will cause the corresponding guide rod 306 to slide within the sliding sleeve rod 305. The connecting sleeve plate 3 is provided with a fitting groove that matches the reinforcing inclined plate 202. The two connecting sleeve plates 3 can be respectively fitted onto the reinforcing inclined plates 202 of the two load-bearing frames 2. Then, the mounting screw 301 is passed through the connecting sleeve plate 3 and the reinforcing inclined plate 202, and nuts 302 are screwed onto both ends of the mounting screw 301 to fix the connecting sleeve plate 3 onto the reinforcing inclined plate 202. After the connection is completed, the adjacent load-bearing frames 2 can form a whole. To improve stability, the movable sleeve 401 can be grasped and the threaded adjusting sleeve 404 rotated. The continuously rotating threaded adjusting sleeve 404 can move through the threaded hole 405 and the threaded engagement with the support rod 4, allowing the threaded adjusting sleeve 404 to drive the movable sleeve 401 to slide on the support rod 4, so that the movable sleeve 401 can drive the connecting seat 402 to contact the ground. The moving distance of the movable sleeve 401 can be adjusted according to the distance between the connecting sleeve 3 and the ground. Then, the fixing rod 403 can be passed through the connecting seat 402 and inserted into the ground to fix one end of the movable sleeve 401, or bolts can be inserted into the connecting seat 402 to fix it to other support components. The setting of the support rod 4 and the movable sleeve 401 can provide lateral support for the connecting sleeve 3 and the load-bearing frame 2, further improving its stability. After completion, the jack 201 on the load-bearing frame 2 can be opened to lift the bridge plate 101 with its output end, making it convenient to replace the support between the base 1 and the bridge plate 101.

[0062] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
