Description

Technical Field

[0001] The present invention relates to the technical field of steel structure bridge reinforcement, and particularly relates to a steel structure bridge reinforcement device and system. Background Art

[0002] A steel structure bridge, also known as a steel truss bridge or a steel bridge, is a bridge whose main load-bearing structure is made of steel. The steel truss bridge constructs the main beam and the support structure through steel, and can bear large loads, including its own weight, the weight of vehicles, and external forces brought by natural disasters such as wind and earthquakes. At the same time, steel structure components can generally be prefabricated in the factory, and only assembly and welding are required on site, which greatly shortens the construction period and reduces the construction cost. Therefore, with its unique advantages and broad application prospects, it plays an increasingly important role in modern bridge engineering;

[0003] To enhance the stability and load-bearing capacity of steel structure bridges, corresponding steel structure bridge reinforcement devices generally need to be set up to reinforce the steel structure bridges. When setting up the existing steel structure bridge reinforcement devices, it is usually necessary for workers to detect the positions that need to be reinforced in advance, and then set up the reinforcement devices according to the situation. When installing the existing processing devices, it is usually necessary to manually tighten the bolts and set up the support structure. Moreover, as the processing position changes, the operating position of the operator and the installation equipment that needs to be used also need to continuously adjust the position, resulting in the actual setting process of the existing bridge processing devices being very cumbersome.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0030] See also Figures 1 to 9, the present invention provides a steel structure bridge reinforcement device and system: including a bridge main body 101, a fixing frame 102 and a reinforcement component. The reinforcement component includes an assembly frame 103, a support frame 104, a lifting frame 105, a moving member and a cooperating member. The moving member includes a moving side plate 201, a driving side plate 202 and a screw driving mechanism 203. The cooperating member includes a driving rack 301, a driving gear shaft 302, a groove sleeve 303, a transmission mechanism 304 and a splicing component. The splicing component includes an insertion rotating shaft 305, a rotating motor 306, an adsorption module 307 and an electromagnetic plate 308. Through the foregoing solution, it is solved that in order to enhance the stability and bearing capacity of a steel structure bridge, a corresponding steel structure bridge reinforcement device generally needs to be set up to reinforce the steel structure bridge. When setting up the existing steel structure bridge reinforcement device, it is usually necessary for the staff to detect the position to be reinforced in advance, and then set up the reinforcement device according to the situation. When installing the existing processing device, it usually requires manual tightening of bolts and setting of the support structure. Moreover, as the processing position changes, the operating position of the operator and the installation equipment to be used also need to continuously adjust the position, resulting in the problem that the existing bridge processing device is very cumbersome in the actual setting process.

[0031] Further, the fixing frame 102 is installed below the bridge main body 101 and further includes a reinforcement component;

[0032] The reinforcement component includes an assembly frame 103, a support frame 104, a lifting frame 105, a moving member and a cooperating member;

[0033] The assembly frame 103 is connected to the fixing frame 102 through the moving member. The support frame 104 is arranged on one side of the fixing frame 102 close to the assembly frame 103. The lifting frame 105 is slidably installed on the support frame 104. The moving member is connected to the fixing frame 102 and is used to drive the assembly frame 103 to move. The cooperating member is connected to the assembly frame 103 and is used to drive the lifting frame 105.

[0034] Specifically, the fixing frame 102 is installed on two adjacent support columns at the bottom of the bridge main body 101 through two set rings and corresponding bolts. The bottom of the fixing frame 102 is provided with reinforcing ribs to facilitate strengthening the support strength of the fixing frame 102;

[0035] The assembly frame 103 and the support frame 104 are both arranged on the fixed frame 102. Above the support frame 104, there is a propping frame 105. The assembly frame 103 can drive the support frame 104 erected on the fixed frame 102 to move through the moving member and the matching member, thereby changing the actual support position of the support frame 104. Then, by driving the propping frame 105 to move upward on the support frame 104, the support frame 104 and the propping frame 105 can form a corresponding reinforcement support structure, thereby reinforcing and supporting the bottom of the bridge main body 101. Moreover, driving the support frame 104 to move on the fixed frame 102 by the assembly frame 103 can quickly determine the position of the support frame 104. When installing this solution, the user only needs to install the support frame 104 so that the support frame 104 is erected on the fixed frame 102, and then push the support frame 104 to the corresponding position for installation through the assembly frame 103 arranged on the fixed frame 102 and the corresponding matching member and moving member. When installing, there is no need for manual high-altitude operation, nor for manual adjustment of the support position, realizing the automatic erection of the steel structure bridge through the provided components, making the setting process of the entire bridge reinforcement device more convenient and fast.

[0036] Further, the moving member includes a moving side plate 201, a driving side plate 202, and a screw driving mechanism 203. The moving side plate 201 is connected to the assembly frame 103 by bolts and is slidably installed on the fixed frame 102; the driving side plate 202 is connected to the assembly frame 103 by bolts and is slidably installed on the fixed frame 102; the screw driving mechanism 203 is connected to the fixed frame 102 and is used to drive the driving side plate 202 to move.

[0037] When this embodiment is in use, the moving side plate 201 and the driving side plate 202 are respectively arranged in the guide grooves on both sides of the assembly frame 103. The screw driving mechanism 203 is composed of a corresponding screw and a motor for driving the screw to rotate. The driving side plate 202 is provided with a threaded hole for matching with the screw inside the screw driving mechanism 203. The structural shapes of the moving side plate 201 and the driving side plate 202 are similar. At the same time, threaded holes for bolt installation are arranged on both sides of the moving side plate 201 and the driving side plate 202. The assembly frame 103 can be installed on the corresponding side of the moving side plate 201 and the driving side plate 202 through the clamping bracket at the bottom and the corresponding bolts. According to the actual assembly situation, the user can choose to adjust the installation position of the assembly frame 103;

[0038] During actual use, the user can drive the driving side plate 202 to move through the screw driving mechanism 203, and then drive the assembly frame 103 to move through the driving side plate 202. The moving side plate 201 provided on the other side of the assembly frame 103 can ensure the stability of the overall position of the assembly frame 103 during movement, thereby realizing the stable pushing of the support frame 104.

[0039] Further, the driving rack 301 is fixedly installed on one side of the propping frame 105; the driving gear shaft 302 meshes with the driving rack 301 and is rotatably installed in the support frame 104; the groove sleeve 303 is connected to the driving gear shaft 302 through the transmission mechanism 304, and the groove sleeve 303 is rotatably installed on one side of the support frame 104; the transmission mechanism 304 is connected to the groove sleeve 303 for realizing the connection between the driving gear shaft 302 and the groove sleeve 303; the splicing member is connected to the assembly frame 103 for cooperating with the groove sleeve 303.

[0040] Further, the insertion rotating shaft 305 is connected to the groove sleeve 303 and is rotatably installed on one side of the assembly frame 103; the output shaft of the rotating motor 306 is connected to the insertion rotating shaft 305, and the rotating motor 306 is fixedly installed in the assembly frame 103; the adsorption module 307 is installed on one side of the support frame 104 close to the assembly frame 103; the electromagnetic plate 308 is fixedly installed on one side of the assembly frame 103 close to the adsorption module 307.

[0041] When this embodiment is in use, the driving rack 301 is fixedly arranged on the back side of the propping frame 105, the driving rack 301 cooperates with the gear on the driving gear shaft 302 arranged in the support frame 104, and the driving gear shaft 302 is connected to the groove sleeve 303 rotatably installed on the outer side of the bottom of the support frame 104 through the transmission mechanism 304;

[0042] The transmission mechanism 304 is mainly composed of two gears and corresponding chains. The two corresponding gears are connected through the chain, thereby realizing the transmission of the fixed shafts on the two gears. The driving gear shaft 302 and the groove sleeve 303 are respectively fixedly installed with the two gears arranged inside the transmission mechanism 304, so as to realize the transmission between the driving gear shaft 302 and the groove sleeve 303 through the arranged transmission mechanism 304;

[0043] A corresponding hexagonal hole is provided on the outer side of the groove sleeve 303, and a hexagonal boss matching the hexagonal hole on the outer side of the groove sleeve 303 is provided at the end of the insertion rotating shaft 305. The insertion rotating shaft 305 is driven by the rotating motor 306. When the corresponding side surfaces of the assembly frame 103 and the support frame 104 are tightly fitted, the hexagonal boss at the end of the insertion rotating shaft 305 will cooperate with the hexagonal hole inside the groove sleeve 303. Then, when the rotating motor 306 drives the insertion rotating shaft 305 to rotate, the insertion rotating shaft 305 can drive the groove sleeve 303 to rotate. In this way, the driving gear shaft 302 can be driven through the provided transmission mechanism 304. When the driving gear shaft 302 rotates, the driving rack 301 will drive the support frame 105 to move on the support frame 104 under the drive of the driving gear shaft 302, and finally complete the drive of the support frame 104;

[0044] To ensure the stable cooperation between the support frame 104 and the assembly frame 103, an adsorption module 307 with a certain range is provided on the side of the support frame 104, and a corresponding electromagnetic plate 308 is provided on the top of the assembly frame 103. The electromagnetic plate 308 generates a magnetic force, and then cooperates with the adsorption module 307 to adsorb and cooperate the support frame 104 and the assembly frame 103, so that the support frame 104 can move stably under the drive of the assembly frame 103.

[0045] Preferably, the reinforcement assembly further includes a support wheel frame 401, a guide wheel frame 402, a limiting member, and a mounting member. The limiting member includes a guide frame 403, a support sliding frame 404, a swing bracket 405, and a swing motor 406. The mounting member includes a main shaft rod 501, an inner friction cylinder 502, a driving mechanism 503, a locking member, and an access driving member. The locking member includes an inner rotating cylinder 504, a mounting bolt 505, an upper pushing plate 506, and an upper pushing spring 507. The access driving member includes a sleeve gear 508, a linkage gear shaft 509, a hole sleeve 510, a displacement transmission mechanism 511, an insertion rod shaft 512, and a mounting motor 513.

[0046] Furthermore, the support wheel frame 401 is installed at the bottom of the support frame 104; the two guide wheel frames 402 are installed on both sides of the support frame 104 through bolts; the limiting member is connected to the support frame 104 and is used to limit the support frame 105 after it moves upward; the mounting member is connected to the assembly frame 103 and is used to realize the installation between the support frame 105 and the bridge main body 101.

[0047] Specifically, the support wheel frame 401 and the guide wheel frame 402 are both provided with corresponding support wheels. The support wheel frame 401 is arranged at the bottom of the support frame 104, and the guide wheel frame 402 is installed on both sides of the support frame 104 by bolts. The support wheel of the support wheel frame 401 contacts the surface of the fixed frame 102, and the support wheel of the guide wheel frame 402 contacts the bottom of the fixed frame 102. So that when the cooperation frame drives the support frame 104 to move, the support frame 104 can move more stably and quickly through the two wheel frames provided.

[0048] Further, the guide frame 403 is fixedly installed on one side of the support frame 104; the support sliding frame 404 is slidably installed on the guide frame 403; the swing bracket 405 is rotatably installed on the assembly frame 103; the output shaft of the swing motor 406 is connected to the swing bracket 405, and the swing motor 406 is fixedly installed on the assembly frame 103.

[0049] When this embodiment is in use, the guide frames 403 are correspondingly arranged on both sides of the top of the support frame 104. The support sliding frame 404 is slidably installed on each guide frame 403. The support sliding frame 404 is provided with two insertion limit platforms, and the side plate of the lifting frame 105 is provided with limit insertion holes that cooperate with the insertion limit platforms of the support sliding frame 404. At the same time, the support frame 104 is also provided with corresponding through holes at the corresponding positions where the support sliding frame 404 is arranged for the support sliding frame 404 to slide in. So that when the lifting frame 105 rises to the corresponding height, the support sliding frame 404 can cooperate with the limit insertion holes on the side plate of the lifting frame 105 by sliding in, thereby completing the support and limit of the bottom of the lifting frame 105;

[0050] There are two sets of the swing brackets 405 and the swing motors 406 in total. The two sets of the swing brackets 405 and the swing motors 406 are respectively arranged on both sides of the assembly frame 103. The corresponding swing brackets 405 are driven to rotate by the swing motors 406, and then the corresponding support slide frames 404 on the support frame 104 are squeezed and pushed by the swing brackets 405, so as to complete the corresponding driving of the two support slide frames 404 on both sides. Corresponding inclined platforms are also arranged inside the support slide frames 404, and corresponding inclined surfaces are also arranged at the ends of the swing brackets 405, so that when removing a specified support structure, the swing brackets 405 can be first rotated to a position in contact with the side wall of the support frame 104, and then the two swing brackets 405 on both sides are inserted from the sides of the support slide frames 404 by the movement of the assembly frame 103, so as to drive the two support slide frames 404 on both sides to move towards both sides. When the lifting frame 105 moves down and retracts later, the two swing brackets 405 on both sides can be rotated outwards to drive the two support slide frames 404 on both sides to slide outwards, so that the lifting frame 105 can slide down by itself.

[0051] Further, the main shaft rod 501 is connected to the assembly frame 103 through the access driving component and is rotatably installed on one side of the lifting frame 105; the inner friction cylinder 502 is connected to the main shaft rod 501 through the driving mechanism 503 and is rotatably installed inside the lifting frame 105; the driving mechanism 503 is connected to the lifting frame 105 and is used to transmit the rotation of the main shaft rod 501 to the inner friction cylinder 502; the locking component is connected to the inner friction cylinder 502 and is used for assembling the lifting frame 105; the access driving mechanism is connected to the assembly frame 103 and is used to drive the main shaft rod 501 to rotate.

[0052] Further, the inner rotating cylinder 504 is installed on the inner friction cylinder 502; the mounting bolts 505 are arranged on the inner rotating cylinder 504; the upper pushing plate 506 is slidably installed inside the inner rotating cylinder 504; both sides of the upper pushing spring 507 are respectively connected to the upper pushing plate 506 and the inner rotating cylinder 504.

[0053] Further, the inserted gear 508 is slidably connected to the main spindle 501 and rotatably mounted on one side of the support frame 104; the linkage gear shaft 509 is connected to the inserted gear 508 and rotatably mounted on the support frame 104; the hole sleeve 510 is connected to the linkage gear shaft 509 through the position-changing transmission mechanism 511, and the hole sleeve 510 is rotatably mounted on one side of the support frame 104 close to the assembly frame 103; the position-changing transmission mechanism 511 is connected to the support frame 104 for realizing the transmission between the hole sleeve 510 and the linkage gear shaft 509; the insertion rod shaft 512 is connected to the hole sleeve 510 and rotatably mounted on one side of the assembly frame 103; the output shaft of the installation motor 513 is connected to the insertion rod shaft 512, and the installation motor 513 is fixedly mounted in the assembly frame 103.

[0054] When in use in this embodiment, the bottom of the main spindle 501 is a hexagonal column, the main spindle 501 is rotatably mounted in the support frame 105, and four groups of the inner friction cylinders 502 and the corresponding driving mechanisms 503 and locking components are arranged at the four corners of the support frame 105. The driving mechanism 503 has the same structure as the transmission mechanism 304, and both realize the corresponding transmission through the cooperation of two gears and a tooth chain. The four inner friction cylinders 502 are connected to the same main spindle 501 through four groups of the driving mechanisms 503.

[0055] An inner rotating cylinder 504 is arranged in each inner friction cylinder 502, and a corresponding friction layer is arranged on the outer side wall of the inner friction cylinder 502 in contact with the inner rotating cylinder 504, so that when the inner friction cylinder 502 rotates, the inner rotating cylinder 504 can rotate under the action of friction.

[0056] A corresponding mounting bolt 505 is arranged in each inner rotating cylinder 504. The screw rod of the mounting bolt 505 penetrates through the through hole arranged at the top of the support frame 105. The hexagonal surface at the bottom of the mounting bolt 505 is adapted to the sliding groove arranged in the inner rotating cylinder 504, and a push plate 506 and a push spring 507 are further arranged in the corresponding sliding groove.

[0057] Construction workers can set the corresponding threaded holes in advance according to the support positions, and then fix the support frame 105 by installing the mounting bolts 505 through the threaded holes. When installing the mounting bolts 505, the support frame 105 can first move upward on the support frame 104 to the bottom of the bridge deck. At this time, the four mounting bolts 505 provided at the top of the support frame 105 will squeeze the corresponding upper push plates 506 and the upper push springs 507 to contract. Then, by rotating the main spindle 501, the four inner friction cylinders 502 and the corresponding inner rotating cylinders 504 are driven to rotate. Furthermore, by rotating the inner rotating cylinder 504, the corresponding mounting bolts 505 are driven to rotate, so as to facilitate the corresponding installation of the four mounting bolts 505;

[0058] Since it is impossible for the four mounting bolts 505 to maintain the same tightening progress during actual cooperation, there will be a small difference among the four mounting bolts 505. Therefore, when one of the mounting bolts 505 is tightened, the corresponding inner friction cylinder 502 will still rotate. Since the inner friction cylinder 502 and the inner rotating cylinder 504 are driven by friction, when the inner rotating cylinder 504 cannot drive the mounting bolt 505 to continue installation, the inner friction cylinder 502 will overcome the friction generated between it and the inner rotating cylinder 504 and then rotate relative to the inner rotating cylinder 504. At this time, the mounting bolt 505 that has not been tightened can continue to be installed, so as to ensure that the multiple mounting bolts 505 set can all be stably and firmly installed. When installing the four mounting bolts 505, the operator can set the corresponding rubber pads or anti-slip pads according to the actual situation to ensure the stable installation and cooperation between the support frame 105 and the bottom of the bridge deck. Moreover, when tightening and installing, since the mounting bolt 505 will continuously receive the thrust brought by the upper push spring 507 in cooperation with the upper push plate 506, the mounting bolt 505 can also maintain stable installation and cooperation when mating with the threaded holes at the corresponding positions;

[0059] The hexagonal column at the bottom of the main spindle rod 501 matches the hexagonal groove provided in the inserted gear 508. The inserted gear 508 is rotatably arranged at the top of the support frame 104. The gear provided at the top of the linkage gear shaft 509 meshes with the inserted gear 508. The bottom of the linkage gear shaft 509 is connected to the hole sleeve 510 through the transmission direction-changing mechanism 511. The transmission direction-changing mechanism 511 is mainly composed of two meshing bevel gears. By setting the two bevel gears, the transmission direction can be changed, thereby realizing the transmission cooperation between the hole sleeve 510 and the linkage gear shaft 509. The hole sleeve 510, the inserting rod shaft 512, the mounting motor 513, the groove sleeve 303, the inserted rotating shaft 305, and the rotating motor 306 have the same principle and function. They all complete splicing and driving after the assembly frame 103 and the support frame 104 are matched. It should be noted that in order to quickly complete the cooperation between the inserting rod shaft 512 and the hole sleeve 510 and between the inserted rotating shaft 305 and the groove sleeve 303, the mounting motor 513 and the rotating motor 306 are both motors without a self-locking structure. At the same time, the end faces of the inserting rod shaft 512 and the inserted rotating shaft 305 for cooperation are provided with corresponding inclined surfaces, so that when the assembly frame 103 moves towards the support frame 104, the corresponding shaft rods can quickly be spliced and cooperated with the slot holes at the designated positions.
