Abstract
Description
Technical Field
[0001] This disclosure belongs to the field of bridge assembly technology, specifically relating to a fully bolted segmental cantilever bridge and its assembly equipment. Background Technology
[0002] A bridge is generally a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, substructure, supports, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations. Supports are force-transmitting devices installed at the points where the bridge span structure supports the piers or abutments. Ancillary structures refer to bridge approach slabs, tapered slopes, revetments, and diversion works, etc.
[0003] During bridge splicing construction, jacking devices are generally required to assist in the splicing process and to support the bridge or other structures. For example, when the two ends of a bridge are brought together, various existing devices are needed to splice them. Additionally, some structures may need to be installed on the bridge. These structures can all be lifted by jacking devices to transport them to the target area. However, when using current hydraulic jacks on the top of the bridge, the contact area between the bottom of the jack and the bridge is relatively small, resulting in high pressure. This high pressure can damage the bridge surface, and the small contact area combined with the large force makes it easy for the hydraulic jack to fly off, causing unnecessary accidents. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a fully bolted segmental cantilever bridge and its assembly equipment, which solves the problem that the small contact area between the lifting device and the bridge leads to high pressure, which may cause damage to the bridge surface.
[0005] The objective of this disclosure can be achieved through the following technical solutions:
[0006] A fully bolted segmental cantilever bridge and its assembly equipment, comprising:
[0007] Support platform, used to support the drive unit;
[0008] The drive unit, located on the top of the support platform, is used to drive the lifting assembly to lift the object.
[0009] A lifting assembly is positioned above the drive unit to complete the lifting operation of the object;
[0010] The equipment includes two support components, which are symmetrically arranged on both sides of the support platform to cooperate with the support platform to support the drive unit, thereby increasing the contact area between the splicing equipment and the structure supporting it.
[0011] Among them, the support components all include a first support member that is detachably connected to the bottom of the support platform. The upper end of the first support member is provided with a first recess. The first support member is provided with several second recesses distributed along the extension direction of the first support member. The second recesses are all connected to the adjacent first recesses. The end of the second recess that is away from the first recess is all through the corresponding first support member.
[0012] Each of the second recesses contains a first placement plate. The end of the first placement plate closest to the first recess is connected to a first connector, and the end of the first placement plate furthest from the first connector is connected to a second support.
[0013] The top of each of the first support members is slidably connected to a first cover plate.
[0014] In some embodiments, the output end of the drive unit is connected to a second connector, and the upper end of the second connector is provided with a third recess.
[0015] The lifting assembly includes a first splice piece with one end inserted into a third recess, and a second splice piece sleeved on the outside of the first splice piece.
[0016] In some embodiments, a fourth annular groove is provided in the middle of the second splicing member, and at least one third splicing member is inserted into the fourth annular groove.
[0017] In some embodiments, a third connector is connected to one side of the drive unit, and a fourth connector is connected to both sides of the third connector, with a limit component provided on any one of the fourth connectors.
[0018] In some embodiments, the limiting component includes a plurality of vertically distributed first limiting members, each of which is slidably connected to a fourth connecting member, and the end of each first limiting member away from the output end of the drive unit is connected to the fourth connecting member by an elastic member.
[0019] In some embodiments, the same second placement plate is placed on the side of the elastic member away from the output end of the drive unit. The second placement plate is connected to the adjacent fourth connector, and a first through hole is provided on the second placement plate.
[0020] The side of the first limiting member away from the output end of the drive unit is connected to a fifth connecting member. One end of the fifth connecting member is inserted through the first through hole. The end of the fifth connecting member away from the output end of the drive unit and the third connecting member is provided with a fifth recess.
[0021] Each of the fifth recessed parts is inserted with a second limiting member. Each second limiting member includes a first limiting plate with one end inserted into the fifth recessed part, a first rotating member connected to the first limiting plate, and a second limiting plate connected to the side of the first rotating member away from the first limiting plate. Each first rotating member is rotatably connected to the second placement plate.
[0022] In some embodiments, a sixth connector is detachably sleeved on the outer side of the output end of the drive unit, a seventh connector is connected to the outer wall of the sixth connector, and a plurality of second through holes are provided on the seventh connector, with a toggle plate inserted into at least one of the second through holes.
[0023] The beneficial effects of this disclosure are:
[0024] 1. This application sets up a support component and a support platform to support the drive unit, thereby increasing the contact area between the splicing equipment and the structure supporting it, avoiding excessive pressure due to a small contact area, and thus avoiding damage to the bridge surface and the situation where the hydraulic jacks fly off.
[0025] 2. Based on the second splicing component, this application sets a third splicing component to cooperate with the second splicing component to complete the lifting, so as to adjust the contact area between the lifting component and the lifted structure and avoid the pressure being too large due to the small contact area.
[0026] 3. When the drive unit malfunctions, it can easily affect subsequent lifting operations and even cause objects to fall, thus affecting the progress of the entire project. The limit component can serve as an anti-accident device for the lifting component, thereby improving the practicality of this application.
[0027] 4. This application provides a limiting combination structure for the first limiting member and the elastic member to prevent the first limiting member and the elastic member from easily entering the limiting state when it is not necessary to limit the output end of the drive unit.

[0036] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0037] like Figures 1 to 7 As shown, a fully bolted segmental cantilever bridge and its assembly equipment include:
[0038] Support platform 1 is used to support drive unit 2;
[0039] Drive unit 2, located on top of support platform 1, is used to drive lifting assembly 13 to lift the object;
[0040] The lifting assembly 13 is positioned above the drive unit 2 to complete the lifting operation of the object;
[0041] And support components 5, there are two support components 5, which are symmetrically arranged on both sides of the support platform 1, and are used to cooperate with the support platform 1 to support the drive unit 2, so as to expand the contact area between the splicing equipment and the structure supporting it.
[0042] Among them, each of the support components 5 includes a first support member 6 that is detachably connected to the bottom of the support platform 1. Each of the first support members 6 has a first recess 7 at its upper end. Each of the first support members 6 has a plurality of second recesses 8 distributed along the extension direction of the first support member 6. Each of the second recesses 8 is connected to the adjacent first recess 7. The end of the second recess 8 that is away from the first recess 7 passes through the corresponding first support member 6.
[0043] Each of the second recessed parts 8 has a first placement plate 9 placed inside it. The first placement plate 9 is connected to a first connector 10 at the end near the first recessed part 7, and the first placement plate 9 is connected to a second support 11 at the end away from the first connector 10.
[0044] The top of each of the first support members 6 is slidably connected to a first cover plate 12.
[0045] During bridge splicing construction, jacking devices are generally required to assist in the splicing process and to support the bridge or other structures. For example, when the two ends of a bridge are brought together, various existing devices are needed to splice them. Additionally, some structures may need to be installed on the bridge. These structures can all be lifted by jacking devices to transport them to the target area. However, when using current hydraulic jacks on the top of the bridge, the contact area between the bottom of the jack and the bridge is relatively small, resulting in high pressure. This high pressure can damage the bridge surface, and the small contact area combined with the large force makes it easy for the hydraulic jack to fly off, causing unnecessary accidents.
[0046] In actual implementation, the drive unit 2 can be configured as a hydraulic cylinder, which drives the lifting assembly 13 to complete the lifting operation of the object. In addition, the support assembly 5 cooperates with the support platform 1 to support the drive unit 2, thereby increasing the contact area between the splicing equipment and the structure supporting it.
[0047] During use, the support component 5 is supported by the first support member 6, which supports other structures in the support component 5. The first support member 6 and the support platform 1 are detachably connected. For example, the two can be connected by plugging. With this setting, when the support component 5 is not in use, the support component 5 can be disassembled to avoid the splicing equipment occupying a large area due to the placement of the first support member 6 and other structures.
[0048] The length of the first support member 6 and the number of the second recessed members 8 can be set appropriately. When providing support, the number of the first placement plate 9 is selected according to the support requirements. The number of the second support members 11 is also adjusted according to the number of the first placement plate 9. The actual support is provided by the second support members 11. Before support, the first cover plate 12 needs to be slid. Through the limiting of the second recessed members 8 and the first cover plate 12, the second support member 11 is limited in all directions while completing the quick limiting, so that it is quickly restricted to the predetermined area and can be quickly disassembled.
[0049] In some embodiments, the output end of the drive unit 2 is connected to a second connector 3, and a third recess 4 is provided on the upper end of the second connector 3.
[0050] The lifting assembly 13 includes a first splice 14 with one end inserted into the third recess 4 and a second splice 15 sleeved on the outside of the first splice 14.
[0051] The lifting assembly 13 is driven by the drive unit 2 and limited and fixed by the second connector 3. By setting the first splicing piece 14, one end of the lifting assembly 13 is inserted into the third recessed piece 4, so that the lifting assembly 13 can be limited and fixed in the horizontal direction and is easy to disassemble.
[0052] In some embodiments, a fourth annular groove 16 is provided in the middle of the second splicing member 15, and at least one third splicing member 17 is inserted into the fourth annular groove 16.
[0053] The shapes of the first splicing component 14 and the second splicing component 15 can be selected, and since the lifting component 13 is easy to disassemble, it is also easy to adjust the shapes of the first splicing component 14 and the second splicing component 15.
[0054] Based on the second splicing component 15, this application provides a third splicing component 17 to cooperate with the second splicing component 15 to complete the lifting, so as to adjust the contact area between the lifting component 13 and the lifted structure and avoid the pressure being too large due to the small contact area.
[0055] In some embodiments, a third connector 18 is connected to one side of the drive unit 2, and a fourth connector 19 is connected to both sides of the third connector 18, with a limit component provided on any one of the fourth connectors 19.
[0056] The third connector 18 can support the limiting component, but the third connector 18 is not connected to the output end of the drive unit 2. The limiting component does not move synchronously with the lifting component 13. The limiting component can be set to one or two, depending on the actual limiting requirements.
[0057] When the drive unit 2 malfunctions, it can easily affect subsequent lifting operations and even cause objects to fall, thus affecting the progress of the entire project. The limit component can serve as an anti-accident device for the lifting component 13.
[0058] In some embodiments, the limiting component includes a plurality of vertically distributed first limiting members 20, all of which are slidably connected to the fourth connecting member 19, and the ends of the first limiting members 20 away from the output end of the drive unit 2 are connected to the fourth connecting member 19 by an elastic member 21.
[0059] As the drive unit 2 gradually operates, the output end of the drive unit 2 gradually rises. During this process, the output end of the drive unit 2 can be limited in the vertical direction by the sliding of the first limiting member 20. The first limiting member 20 can only move in the horizontal direction. When the drive unit 2 malfunctions and causes the output end of the drive unit 2 and the lifting assembly 13 to fall, the first limiting member 20 limits their falling height.
[0060] In the actual limiting process, the first limiting member 20 is initially attached to the output end of the drive unit 2. The elastic member 21 can be a spring and is initially in a compressed state. When the output end of the drive unit 2 gradually rises, the obstruction of the first limiting member 20 separated from it is released. Under the push of the corresponding spring, it slides to directly below the output end of the drive unit 2. There are multiple first limiting members 20, which can limit and support the output end of the drive unit 2 from multiple heights.
[0061] In some embodiments, the elastic member 21 is placed on the side away from the output end of the drive part 2 with the same second placement plate 22. The second placement plate 22 is connected to the adjacent fourth connector 19. The second placement plate 22 has a first through hole 23.
[0062] The first limiting member 20 is connected to a fifth connecting member 24 on the side away from the output end of the driving part 2. One end of the fifth connecting member 24 is inserted through the first through hole 23. A fifth recess is opened on the end of the fifth connecting member 24 away from the output end of the driving part 2 and the third connecting member 18.
[0063] Each of the fifth recessed parts is inserted with a second limiting member. Each second limiting member includes a first limiting plate 29 with one end inserted into the fifth recessed part, a first rotating member 30 connected to the first limiting plate 29, and a second limiting plate 31 connected to the side of the first rotating member 30 away from the first limiting plate 29. Each first rotating member 30 is rotatably connected to the second placement plate 22.
[0064] Considering that the first limiting member 20 and the elastic member 21 can easily enter the limiting state without limiting the output end of the drive unit 2 without any restriction, this application sets the above structure to form a limiting combination structure for the first limiting member 20 and the elastic member 21.
[0065] Initially, the elastic element 21 is in a compressed state. However, because the first limiting plate 29 obstructs the reset movement of the fifth connecting member 24, the elastic element 21 remains in a compressed state and cannot be restored. With this setting, the restriction can be quickly released while efficiently restricting the first limiting member 20 and the elastic element 21.
[0066] In some embodiments, a sixth connector 25 is detachably sleeved on the outer side of the output end of the drive unit 2, and a seventh connector 26 is connected to the outer wall of the sixth connector 25. The seventh connector 26 has a plurality of second through holes 27, and a toggle plate 28 is inserted into at least one second through hole 27.
[0067] By setting the toggle plate 28, when it moves toward the output end of the drive unit 2, it can gradually toggle the second limiting plate 31 that is in contact with it to rotate, thereby causing the first limiting plate 29 to disengage from the fifth recessed member. At this time, the squeezed state of the elastic member 21 is released, and the first limiting member 20 begins to slide to directly below the output end of the drive unit 2.
