Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a support structure for bridges. Background Technology

[0002] A bridge is a structure built to allow roads to cross natural or man-made obstacles. Bridge design typically requires consideration of the load-bearing capacity of the beams. Because bridges are typically reinforced concrete structures with a large self-weight, they experience significant stress bending and settlement during crossing, which has a major impact on the bridge's safety profile.

[0003] During bridge construction, in addition to building piers to support the bridge, it is also necessary to set up support structures to temporarily support the unfinished bridge structure. However, existing bridge support structures are usually of fixed height, making it inconvenient to provide height-adjustable support according to different locations of the bridge, i.e., different heights. Temporary pads and other structures are required to support the bridge, resulting in poor stability. Furthermore, the base area of ​​existing bridge support structures is fixed, and the maximum contact area with the ground is the base area. When used on uneven ground, the contact area between the base and the ground is even smaller, making the support structure prone to instability.

[0004] Therefore, there is an urgent need for a bridge support structure to solve the above problems. Utility Model Content

[0005] The first objective of this invention is to provide a bridge support structure to solve the problems of existing bridge support structures having non-adjustable height and poor stability when used on uneven ground.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] Bridge support structures include:

[0008] The base is installed on the ground;

[0009] A support assembly includes a support frame and a support plate, one end of the support frame being fixed to the base, and the support plate being located at the end of the support frame away from the base, for supporting the bridge;

[0010] A lifting assembly, connected to the support plate, is used to drive the support plate to move along a first direction to move closer to or further away from the bridge;

[0011] A reinforcing plate is movably installed inside the base, and part of the reinforcing plate can extend out of the base and contact the ground.

[0012] Furthermore, the base has an installation channel along the second direction, and the two openings of the installation channel extend to the two sides of the base in the second direction, respectively. The reinforcing plate is slidably connected to the installation channel, and a portion of the reinforcing plate can extend out of the installation channel.

[0013] Furthermore, the reinforcing plate has a plurality of first fixing holes on one side in the third direction, and the plurality of first fixing holes are spaced apart along the second direction. The base has a second fixing hole on one side in the third direction that communicates with the installation channel. A first fixing member is connected in the second fixing hole. The first fixing member can pass through the second fixing hole and any of the first fixing holes to fix the reinforcing plate.

[0014] Furthermore, the reinforcing plate is provided with a plurality of third fixing holes, and the base also includes a second fixing member, which can be selectively inserted into any of the third fixing holes.

[0015] Furthermore, two reinforcing plates are provided, both of which are arranged along the second direction and can move towards or away from each other. Multiple second fixing holes are provided, and the multiple second fixing holes are spaced apart in the second direction.

[0016] Furthermore, the lifting assembly includes a driving component, a reversing structure, and a transmission component connected in sequence. The end of the transmission component away from the reversing structure is connected to the support plate. The driving component drives the reversing structure to rotate, thereby causing the transmission component and the support plate to move along the first direction.

[0017] Furthermore, the reversing structure includes a worm, a worm wheel, and a threaded rod connected in sequence. The worm is connected to the driving component, and the transmission component is provided with a thread that cooperates with the threaded rod. The rotation of the threaded rod drives the transmission component to move along the first direction.

[0018] Furthermore, the driving component is inserted through and fixed to the side of the support frame, the driving end of the driving component is located inside the support frame, and the driving end is connected to the worm gear.

[0019] Furthermore, in the third direction, a limiting block is provided on the outer side of the transmission component, and a limiting groove is correspondingly opened on the side of the support frame, with the limiting block slidingly disposed in the limiting groove along the first direction.

[0020] Furthermore, there are two of each of the limiting blocks and the limiting grooves. The two limiting blocks are symmetrically arranged on the outer side of the transmission member in the third direction, and the two limiting grooves are symmetrically arranged on the side of the support frame. The two limiting blocks are slidably arranged in the corresponding limiting grooves along the first direction.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a bridge support structure, including a base, a support assembly, and a lifting assembly. The base is installed on the ground. The support assembly includes a support frame and a support plate. One end of the support frame is fixed to the base, and the support plate is located at the end of the support frame away from the base, used to support the bridge. The lifting assembly is connected to the support plate and is used to drive the support plate to move along a first direction to move closer to or further away from the bridge. A reinforcing plate is movably installed inside the base, and part of the reinforcing plate can extend out of the base and contact the ground. When using this bridge support structure, the lifting assembly drives the support plate to move along the first direction to support the bridge, meeting the support needs of different locations on the bridge. In areas with poor ground flatness, the reinforcing plate extends out of the base and contacts the ground to increase the contact area between the base and the ground, improving the stability of the bridge support structure and providing stable support for the bridge.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] This utility model provides a support structure for bridges, whose support height is adjustable to meet the needs of different locations on the bridge, and has high support stability on uneven ground.

[0038] like Figure 1 As shown, in this utility model, the bridge support structure includes a base 1, a support assembly 2, and a lifting assembly 3. Specifically, the base 1 is installed on the ground. The support assembly 2 includes a support frame 21 and a support plate 22. One end of the support frame 21 is fixed to the base 1, and the support plate 22 is located at the end of the support frame 21 away from the base 1, used to support the bridge. The lifting assembly 3 is connected to the support plate 22 and is used to drive the support plate 22 to move along a first direction (i.e., the height direction of the support frame 21) to move closer to or away from the bridge. A reinforcing plate 11 is movably installed inside the base 1, and part of the reinforcing plate 11 can extend out of the base 1 and contact the ground. It can be understood that when using this bridge support structure, the lifting assembly 3 drives the support plate 22 to move along the first direction to support the bridge, meeting the support requirements of different positions of the bridge. In areas with poor ground flatness, part of the reinforcing plate 11 extends out of the base 1 and contacts the ground to increase the contact area between the base 1 and the ground, improve the stability of the bridge support structure, and support the bridge smoothly.

[0039] Furthermore, such as Figure 2 As shown, an installation channel 12 is provided inside the base 1 along the second direction (i.e., the length direction of the base 1). Two openings of the installation channel 12 extend to two sides of the base 1 in the second direction. A reinforcing plate 11 is slidably connected within the installation channel 12, and a portion of the reinforcing plate 11 can extend out of the installation channel 12. Specifically, the shapes of the installation channel 12 and the reinforcing plate 11 are matched. It can be understood that by providing the installation channel 12 to accommodate the reinforcing plate 11, when the reinforcing plate 11 is needed, a portion of the reinforcing plate 11 can extend out of the installation channel 12 and contact the ground, thereby increasing the contact area between the base 1 and the ground and improving stability. When the reinforcing plate 11 is not needed, it can be pushed back into the installation channel 12, reducing the space occupied by the reinforcing plate 11, avoiding interference between the reinforcing plate 11 and other structures on the construction site, and facilitating transportation.

[0040] For example, the reinforcing plate 11 has a plurality of first fixing holes 111 on one side in the third direction (i.e., the width direction of the base), and the plurality of first fixing holes 111 are spaced apart along the second direction. The base 1 has a second fixing hole 121 on one side in the third direction, which connects to the mounting channel 12. A first fixing member 13 is connected in the second fixing hole 121. The first fixing member 13 can pass through the second fixing hole 121 and any one of the first fixing holes 111 to fix the reinforcing plate 11. Specifically, the axial directions of the first fixing holes 111 and the second fixing holes 121 are both parallel to the second direction, and the second direction is perpendicular to the third direction. It is understandable that whether the reinforcing plate 11 is located inside the installation channel 12 or partially outside the installation channel 12, the position of the reinforcing plate 11 can be fixed through the aforementioned multiple first fixing holes 111, second fixing holes 121, and first fixing member 13 to improve the stability of the reinforcing plate 11. When the reinforcing plate 11 is partially outside the installation channel 12 and in contact with the ground, fixing the position of the reinforcing plate 11 can further improve the stability of the base 1 and the stability of the entire bridge support structure for supporting the bridge. When the reinforcing plate 11 is located inside the installation channel 12, fixing the position of the reinforcing plate 11 can prevent the reinforcing plate 11 from sliding out of the installation channel 12 and interfering with other equipment or construction personnel at the construction site. In this embodiment, the first fixing hole 111 and the second fixing hole 121 can both be threaded holes, and the first fixing member 13 can be a bolt. The specific type is not specifically limited in this embodiment, as long as it meets the usage requirements.

[0041] Of course, in other embodiments, multiple first fixing holes 111 can also be provided on the base 1, and second fixing holes 121 can also be provided on the reinforcing plate 11. Each of the multiple first fixing holes 111 is connected to a first fixing member 13 to achieve the fixing of the reinforcing plate 11.

[0042] Furthermore, the reinforcing plate 11 is also provided with a plurality of third fixing holes 112, and the base 1 also includes a second fixing member (not shown in the figure), which can selectively pass through any of the third fixing holes 112. Specifically, the plurality of third fixing holes 112 are all arranged on the reinforcing plate 11 along the first direction, and the plurality of third fixing holes 112 are spaced apart in the second direction. It can be understood that by providing a plurality of third fixing holes 112, when the reinforcing plate 11 partially extends out of the mounting channel 12, a portion of the third fixing holes 112 also extend out of the mounting channel 12. By having the second fixing member pass through one of the third fixing holes 112 and insert it into the ground, the reinforcing plate 11 can be further fixed. Of course, in other embodiments, a plurality of second fixing members can also be provided, which respectively cooperate with the third fixing holes 112 located outside the mounting channel 12 to fix the reinforcing plate 11.

[0043] For example, the second fastener is a screw, and the third fixing hole 112 is a threaded hole. The screw passes through the threaded hole and is screwed to the ground, which can further improve the fixing effect of the reinforcing plate 11 and ensure the stability of the base 1.

[0044] Furthermore, two reinforcing plates 11 are provided, both arranged along the second direction and capable of moving closer to or further away from each other. Multiple second fixing holes 121 are provided, spaced apart along the second direction. It can be understood that by arranging the two reinforcing plates 11 closer to or further away from each other, the portions of the two reinforcing plates 11 that are further away from each other can extend out of the mounting channel 12, and the portions of the two reinforcing plates 11 that contact the ground are symmetrical, further improving the stability of the base 1. In addition, the multiple second fixing holes 121 further improve the fixing effect of the reinforcing plates 11 and increase the range in which the reinforcing plates 11 can extend.

[0045] Furthermore, regarding the lowering component of this embodiment, the lifting component 3 includes a driving member 31, a reversing structure 32, and a transmission member 33 connected in sequence. The end of the transmission member 33 away from the reversing structure 32 is connected to the support plate 22. The driving member 31 drives the reversing structure 32 to rotate, thereby causing the transmission member 33 and the support plate 22 to move along the first direction. Specifically, the driving member 31 is horizontally arranged. It can be understood that by setting the driving member 31, the reversing structure 32, and the transmission member 33 connected in sequence, the reversal of the driving force output by the horizontally arranged driving member 31 is realized, which facilitates the installation of the driving member 31 while realizing the movement of the support plate 22 along the first direction. In this embodiment, the driving member 31 is a motor. The specific type of the driving member 31 is prior art and will not be described in detail in this embodiment.

[0046] Furthermore, such as Figures 3-4 As shown, the reversing structure 32 includes a worm gear 321, a worm wheel 322, and a threaded rod 323 connected in sequence. Specifically, the worm gear 321 is connected to the driving member 31, and the transmission member 33 has a thread that mates with the threaded rod 323. The rotation of the threaded rod 323 drives the transmission member 33 to move in the first direction. It can be understood that the worm gear 321, worm wheel 322, and threaded rod 323 work together to ensure a stable transmission connection. The threaded rod 323 mates with the transmission member 33, driving the transmission member 33 to move smoothly, thus improving the stability of the support plate 22's movement. In this embodiment, the transmission member 33 can be a square tube with a thread along its length that mates with the threaded rod 323, so that the rotation of the threaded rod 323 drives the transmission member 33 to move in the first direction. Of course, in other embodiments, the transmission member 33 can also be of other shapes, as long as they meet the usage requirements. This embodiment does not specifically limit this.

[0047] For example, such as Figures 1-4As shown, the drive component 31 is inserted through and fixed to the side of the support frame 21. The drive end of the drive component 31 is located inside the support frame 21 and is connected to the worm gear 321. It can be imagined that the drive end of the drive component 31 being located inside the support frame 21 avoids the drive end of the drive component 31 being affected by the outside, ensuring the smoothness of the drive of the drive component 31. The part of the drive component 31 that is far from its drive end is located outside the support frame 21. This part includes the power supply and control module. This arrangement facilitates the electrical connection of the drive component 31 to the external power supply and the control of the operating status of the drive component 31, and reduces the space occupied by the drive component 31 in the support frame 21, which facilitates the installation of the reversing structure 32.

[0048] Furthermore, such as Figure 1 and Figure 3 As shown, in the third direction, a limiting block 331 is provided on the outer side of the transmission component 33, and a limiting groove 211 is correspondingly provided on the side of the support frame 21. The limiting block 331 is slidably disposed in the limiting groove 211 along the first direction. By providing the matching limiting groove 211 and limiting block 331, the transmission component 33 can be prevented from detaching from the support frame 21 and falling accidentally. At the same time, the movement of the transmission component 33 can be guided to avoid instability in its movement.

[0049] For example, two limit blocks 331 and two limit grooves 211 are provided. The two limit blocks 331 are symmetrically arranged on the outer side of the transmission member 33 in a third direction, and the two limit grooves 211 are symmetrically arranged on the side of the support frame 21. The two limit blocks 331 are slidably disposed in the corresponding limit grooves 211 along the first direction. It can be understood that by providing two sets of limit blocks 331 and limit grooves 211, the limiting effect of the transmission member 33 is further enhanced, and the guiding effect of the transmission member 33 is improved, thereby further improving the stability of the movement of the transmission member 33. Of course, in other embodiments, three or four limit blocks 331 and limit grooves 211 may also be provided.

[0050] To further improve the smoothness of the movement of the transmission component 33, the outer shape of the transmission component 33 is matched with the inner shape of the support frame 21. The inner side of the support frame 21 is used to guide the movement of the transmission component 33, thereby improving the smoothness of the movement of the transmission component 33.

[0051] Furthermore, a rubber layer (not shown in the figure) is provided at the end of the support plate 22 away from the base 1. By providing the rubber layer, the support plate 22 is prevented from making hard contact with the bridge, thus avoiding damage to the support plate 22. Moreover, the rubber layer can deform when it comes into contact with the bridge, making it fit the bottom surface of the bridge more closely and further improving the stability of the support.

[0052] In this embodiment, the process of using the bridge support structure is as follows: determine the installation position of the bridge support structure, transport the bridge support structure to the installation position, extend part of the reinforcing plate 11 out of the base 1 to contact the ground, and fix the reinforcing plate 11 to improve the stability of the base 1. Then, drive the support plate 22 to move along the first direction through the lifting assembly 3 until the support plate 22 abuts against the bridge to meet the requirement of stable support for different positions of the bridge.

[0053] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
