Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a lightweight bridge segment moving device. Background Technology

[0002] When bridge segments cannot be directly lowered into place by crane due to site conditions, the segments need to be hoisted to the range where the crane can operate first, and then moved into place by jacking or sliding.

[0003] Currently, the movement of bridge segments mainly relies on the jacking technology of walking jacks. By utilizing the lifting and pushing functions of walking jacks, bridge segments are gradually moved forward through repeated lifting and pushing. Since walking jacks themselves cannot move on their own, manual or mechanical methods are required to move them from one location to another for the next round of jacking.

[0004] However, during continuous construction, for lighter segments (under 200 tons), multiple jacks may need to be deployed to work together to maintain construction efficiency. This, however, increases costs. While manually moving the jacks for turnover can save some costs, it significantly reduces operational efficiency. Utility Model Content

[0005] In view of this, the present invention provides a lightweight bridge segment moving device to solve the problem of the cumbersome construction of walking jacks in the existing design.

[0006] This utility model provides a lightweight bridge segment moving device, comprising: a track, on which a support group is slidably arranged, the support group comprising: a first support and a second support; A first support is slidably disposed on the track. A driving component is disposed on the first support. A first snap-fit ​​component is disposed on the first support. The first snap-fit ​​component has a first state of snapping the first support onto the track for limiting and a second state of releasing the limiting. The second support is slidably disposed on the track near the first support. The driving end of the driving member is connected to the second support. The second support is provided with a second snap-fit ​​member. The second snap-fit ​​member has a third state of snapping the second support onto the track for limiting and a fourth state of releasing the limiting. In use, the item to be transported is placed on the second support. When the first support is in a limiting position with the track, the driving component pushes the second support and the item to be transported toward one end of the track. Then, the second support is in a limiting position, and the driving component retracts to pull the first support forward to reset. This cycle repeats.

[0007] By setting a first support and a second support on the track, the part to be transported is placed on the second support, and the second support and the part to be transported are moved by the drive component, which makes it easier to move the part to be transported. At the same time, only the first support and the second support need to be installed on the track during installation, making it more convenient to install, use and disassemble.

[0008] In one alternative embodiment, the first support is provided with a downward-opening first snap-fit ​​groove, which snaps onto the track, and the driving member is disposed on the side end face of the first support.

[0009] By setting the first locking groove on the first support, the connection between the first support and the rail is made more stable, avoiding shaking during movement and improving the overall stability and safety of operation.

[0010] In one alternative embodiment, a first wear-resistant layer is provided on the first snap-fit ​​groove, and the first wear-resistant layer abuts against the track.

[0011] By setting a first wear-resistant layer on the first card slot, friction loss is effectively reduced and the service life of the device is extended.

[0012] In one optional embodiment, a receiving cavity with an opening facing one side of the second support is provided on the side end face of the first support, and the driving member is installed into the receiving cavity.

[0013] By setting a receiving cavity on the first support, the installation of the drive component is made more concealed, protecting the drive component from external damage.

[0014] In one alternative embodiment, the second support further includes a downward-opening second snap-fit ​​groove, on which a second wear-resistant layer is provided, and the second wear-resistant layer abuts against the track.

[0015] By setting a second locking groove on the first support, the connection between the second support and the rail is more stable, reducing shaking during movement and improving operational stability. The second wear-resistant layer further reduces friction loss and extends the service life of the device.

[0016] In one alternative implementation, the track has two parallel, spaced-apart rails.

[0017] By setting two parallel tracks at intervals, the stability of the first and second supports during movement is ensured, avoiding the risk of deviation caused by a single track, and further improving the stability and reliability of the conveying system.

[0018] In one optional embodiment, the track is provided with a plurality of limiting holes along the length direction of the track; A first snap-fit ​​member is slidably disposed on the first support along the extending direction of the limiting hole. The first snap-fit ​​member is used to be inserted into the limiting hole to limit the first support. A second snap-fit ​​member is slidably provided on the second support along the extension direction of the limiting hole. The second snap-fit ​​member is used to be inserted into the limiting hole to limit the second support.

[0019] By setting limiting holes and snap-fit ​​components on the track, the first and second supports are accurately positioned during movement to prevent accidental slippage, while also limiting the movement of the first and second supports.

[0020] In one alternative embodiment, the system further includes an auxiliary support slidably disposed on the track at one end away from the first support, wherein the component to be transported is placed on the first support and the auxiliary support.

[0021] By setting auxiliary supports, the number of support points for the parts to be transported is increased, the weight is distributed, and overloading of a single support is avoided.

[0022] In one alternative embodiment, the auxiliary support has a downward-opening sliding groove, and the track is slidably disposed within the sliding groove.

[0023] By setting sliding grooves on the auxiliary supports, the track and the auxiliary supports are tightly connected, which enhances the stability of the overall structure and ensures smoothness during movement.

[0024] In one alternative embodiment, a third wear-resistant layer is provided on the sliding groove, and the third wear-resistant layer abuts against the track.

[0025] By adding a third wear-resistant layer to the sliding groove, sliding friction is further reduced, thus lowering energy consumption. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0031] like Figure 1 , Figure 2 As shown, according to an embodiment of the present invention, a lightweight bridge segment moving device is provided, comprising: a track 1, on which a support group is slidably disposed, the support group comprising: a first support 2 and a second support 3; the first support 2 is slidably disposed on the track 1, a driving member 11 is disposed on the first support 2, and a first locking member is disposed on the first support 2, the first locking member having a first state of locking the first support 2 onto the track 1 for limiting and a second state of releasing the limiting; the second support 3 is slidably disposed on the track 1 near the first support 2, the driving end of the driving member 11 is connected to the second support 3, and a second locking member is disposed on the second support 3, the second locking member having a third state of locking the second support 3 onto the track 1 for limiting and a fourth state of releasing the limiting.

[0032] In use, the component to be conveyed is placed on the second support 3. When the first support 2 is positioned relative to the track 1, the drive unit 11 pushes the second support 3 and the component to be conveyed toward one end of the track. Subsequently, the second support 3 is positioned, and the drive unit 11 retracts, pulling the first support 2 forward to reset. This process is repeated cyclically. By setting the first support 2 and the second support 3 on the track 1, placing the component to be conveyed on the second support 3, and then using the drive unit 11 to move the second support 3 and the component to be conveyed, the component to be conveyed can be moved more conveniently. Furthermore, during installation, only the first support 2 and the second support 3 need to be installed on the track 1, making installation, use, and disassembly more convenient.

[0033] like Figure 3 , Figure 4 As shown, in this embodiment, the first support 2 is provided with a downward-opening first locking groove 4, which engages with the track 1. The driving component 11 is disposed on the side end face of the first support 2. By providing the first locking groove 4 on the first support 2, the connection between the first support 2 and the track 1 is made more stable, avoiding shaking during movement and improving the overall stability and safety of operation. It should be noted that, as an alternative implementation, the upper end face of the first locking groove 4 can also be provided with a roller, which can reduce the friction during movement.

[0034] Specifically, the first support 2 includes a first mounting plate and a second mounting plate arranged parallel to each other vertically. A fixing plate is fixedly connected to the upper end face of the first and second mounting plates. The first mounting plate, the second mounting plate, and the fixing plate together form a first snap-fit ​​groove 4. Reinforcing ribs are provided between the first and second mounting plates to enhance structural stability. The fixing plate has mounting holes to facilitate the installation of the driving component 11. The structure of the second support 3 is the same as that of the first support 2, and will not be described again here.

[0035] like Figure 3 As shown, in this embodiment, a first wear-resistant layer 5 is provided on the first locking groove 4. Specifically, the first wear-resistant layer 5 is provided on the inner surfaces of the first mounting plate, the second mounting plate, and the fixing plate. The first wear-resistant layer 5 is made of polytetrafluoroethylene (PTFE). The first wear-resistant layer 5 abuts against the track 1. When the first support 2 moves on the track 1, the first wear-resistant layer 5 rubs against the track 1, reducing damage to the first support 2. Simultaneously, the PTFE plate reduces the coefficient of friction. By providing the first wear-resistant layer 5 on the first locking groove 4, friction loss is effectively reduced, extending the service life of the device. It should be noted that, as an alternative implementation, the first wear-resistant layer 5 can also be made of wear-resistant cast iron.

[0036] like Figure 5As shown, in this embodiment, a receiving cavity 6 with an opening facing the second support 3 is provided on the side end face of the first support 2. The driving component 11 is installed in the receiving cavity 6, and the driving end of the driving component 11 is connected to the second support 3. Specifically, the driving component 11 is a hydraulic cylinder, which is fixed to the first support 2 by bolts, and the driving end of the hydraulic cylinder is fixed to the second support 3 by bolts. By providing the receiving cavity 6 on the first support 2, the installation of the driving component 11 is more concealed, protecting the driving component 11 from external damage. It should be noted that, as an alternative implementation, the receiving cavity 6 may not be provided, and the driving component 11 may be directly machined and installed on the side end face of the first support 2.

[0037] like Figure 5 As shown, in this embodiment, the second support 3 also has a downward-opening second locking groove 7, on which a second wear-resistant layer 8 is provided, and the second wear-resistant layer 8 abuts against the track 1. By providing the second locking groove 7 on the second support 3, the connection between the second support 3 and the track 1 is made more stable, reducing shaking during movement and improving operational stability. The provision of the second wear-resistant layer 8 further reduces friction loss and extends the service life of the device. The structure of the second locking groove 7 is the same as that of the first locking groove 4, and the setting position of the second wear-resistant layer 8 is also the same as that of the first wear-resistant layer 5. The second wear-resistant layer 8 is made of polytetrafluoroethylene. It should be noted that, as an alternative implementation, the second wear-resistant layer 8 can also be made of polyetheretherketone (PEEK) composite material.

[0038] like Figure 1 As shown, in this embodiment, the track 1 has two parallel, spaced-apart rails. A first support 2 and a second support 3 are respectively mounted on the two rails 1. A driving component 11 is mounted on the first support 2, allowing the conveyed component to be placed on the two second supports 3. The parallel spacing of the two rails 1 ensures the stability of the first support 2 and the second support 3 during movement, avoiding the risk of deviation caused by a single rail 1, and further improving the stability and reliability of the conveying system. It should be noted that, as an alternative implementation, the track 1 can also be a single rail, which still allows the first support 2 to move on the track 1.

[0039] like Figure 1As shown, in this embodiment, the track 1 has several limiting holes 9 along its length. The limiting holes 9 are arranged in two rows along the height direction, with multiple holes in each row along the length of the track 1. The limiting holes 9 are located on the side of the track 1. A first locking member is slidably disposed on the first support 2 along the extension direction of the limiting holes 9. The first locking member is used to insert into the limiting holes 9 to limit the first support 2. A second locking member is slidably disposed on the second support 3 along the extension direction of the limiting holes 9. The second locking member is used to insert into the limiting holes 9 to limit the second support 3. The first and second locking members are bolts. The first locking member is disposed on the side end face of the first support 2 and threadedly connected to the first support 2. The second locking member is disposed on the side end face of the second support 3 and threadedly connected to the second support 3. Two first and two second locking members are provided, arranged vertically along the height direction. In use, the first locking member is screwed into the limiting hole 9 to limit the first support 2. The second locking piece is screwed into the limiting hole 9 to limit the second support 3. By setting the limiting hole 9 and the locking piece on the track 1, the first support 2 and the second support 3 are accurately positioned during movement, preventing accidental slippage, and the first support 2 and the second support 3 are limited. The limiting hole 9 is a circular through hole. It should be noted that, as an alternative implementation, the limiting hole 9 can also be set in multiple rows, such as three rows, four rows, etc.

[0040] like Figure 1 , Figure 6 As shown, in this embodiment, an auxiliary support 10 is also included. The structure of the auxiliary support 10 is the same as that of the second support 3. The auxiliary support 10 is slidably disposed on the track 1 at one end away from the first support 2. The part to be conveyed is placed on the first support 2 and the auxiliary support 10. By setting the auxiliary support 10, the support points of the part to be conveyed are increased, the weight is distributed, and overload of a single support is avoided. It should be noted that, as an alternative implementation, the auxiliary support 10 may not be provided, and two second supports 3 may be set on the track 1.

[0041] like Figure 6 As shown, in this embodiment, the auxiliary support 10 has a downward-opening sliding groove. The structure of the sliding groove is the same as the first engaging groove 4 of the first support 2, and the track 1 is slidably disposed within the sliding groove. By providing a sliding groove on the auxiliary support 10, the track 1 is tightly engaged with the auxiliary support 10, enhancing the stability of the overall structure and ensuring smoothness during movement. It should be noted that, as an alternative implementation, a roller can also be provided on the lower end face of the auxiliary support 10, and the roller moves on the track 1.

[0042] like Figure 6As shown, in this embodiment, a third wear-resistant layer, made of polytetrafluoroethylene, is provided on the sliding groove. The third wear-resistant layer abuts against the track 1. By providing a third wear-resistant layer on the sliding groove, sliding friction is further reduced, thus lowering energy consumption.

[0043] Installation method of the lightweight bridge segment moving device: The track 1 has two parallel, spaced-apart rails, and several limiting holes 9 are provided along its length. The support assembly includes a first support 2 and a second support 3. The first support 2 is slidably mounted on the track 1, and has a driving component 11 and a first locking groove 4. The first locking groove 4 is used to securely engage the first support 2 with the track 1. The first wear-resistant layer 5 on the first locking groove 4 is in frictional contact with the track 1. A receiving cavity 6 with an opening facing the second support 3 is provided on the side end face of the first support 2, and the driving component 11 is installed in the receiving cavity 6. The second support 3 is also slidably mounted on the track 1, close to the first support 2. The driving end of the driving component 11 is connected to the second support 3. The second support 3 has a second locking groove 7 and a second wear-resistant layer 8. An auxiliary support 10 is slidably mounted on the track 1 at the end away from the first support 2, and its structure is the same as the second support 3, with a downward-opening sliding groove. The track 1 is positioned within the sliding groove of the auxiliary support 10. A third wear-resistant layer is also provided on the sliding groove.

[0044] The working principle of the lightweight bridge segment moving device: When the first support 2 is confined to the track 1, the drive component 11 extends to move the entire structure forward. When the first support 2 is not confined to the track 1, the drive component 11 retracts to move the first support 2 forward. When the second support 3 is not confined to the track 1, the drive component 11 extends to move the entire structure forward. When the second support 3 is confined to the track 1, the drive component 11 retracts to move the first support 2 forward. When the first support 2 is confined to the track 1, the drive component 11 extends to push the second support 3 forward, carrying the segment forward by 500mm. Subsequently, when the second support 3 is confined, the drive component 11 retracts to pull the first support 2, which has been released from its confined position, forward to reset. This cyclical alternation, through the step-by-step moving mechanism of "drive component 11 extension and retraction + support confined position switching," achieves efficient movement of lightweight bridge segments.
