Description

Technical Field

[0001] This invention relates to the field of bridge transportation technology, and more specifically to a transportation system for the lateral movement of prefabricated bridges. Background Technology

[0002] During the manufacturing process of precast bridges, it is necessary to transfer the precast bridges that have already been manufactured from the production area to the storage area in order to free up sufficient production space in the production area.

[0003] The current main method for handling precast bridges involves first arranging numerous guide rails on the ground, then sliding a large gantry crane along these rails. During operation, jacks are used to lift the precast bridge from the production area, followed by placing steel plates under the bridge to support it. The gantry crane's cables are then secured to these plates, and the crane lifts the bridge, slowly moving it to the storage area and lowering it. However, because the gantry crane can only move in one direction, multiple cranes need to be purchased and installed when the production area is large. This will increase production costs and also prevent the immediate movement of a production area to another available storage area when the storage area corresponding to the production area is full, thus causing the production area to stop working and reducing output. In addition, due to the large weight of the precast bridges, the gantry crane needs to use high-cost, high-power motors when lifting and moving them, resulting in excessive production costs and energy consumption. Furthermore, the heavy weight of the precast bridges will also cause the gantry crane to move them slowly, take a long time, and pose a risk of the precast bridges falling from a height. Summary of the Invention

[0004] This invention proposes a transportation system for the lateral movement of precast bridges, which solves the problems of non-universal storage areas and slow movement speed and high energy consumption of large gantry cranes in related technologies.

[0005] The technical solution of the present invention is as follows: a transportation system for the lateral movement of prefabricated bridges, including a foundation, wherein a pit is formed on the upper surface of the foundation;

[0006] Multiple unidirectional guide rail mechanisms are arranged at equal intervals at the bottom of the pit cavity;

[0007] The unidirectional guide rail mechanism includes a first support base, which is fixedly installed on one side of the bottom surface of the foundation pit. An arc-shaped support base fixedly connected to the bottom surface of the foundation pit is fixedly installed on the other side of the first support base. The height of the upper surface of one side of the arc-shaped support base is greater than the height of the upper surface of the other side. A second support base fixedly connected to the bottom surface of the foundation pit is fixedly installed on the other side of the arc-shaped support base.

[0008] A slide rail mechanism is provided on the upper surfaces of the foundation, the first support seat, and the arc-shaped support seat;

[0009] A deceleration mechanism is disposed on the upper surface of the second support base;

[0010] A bridge-carrying mechanism, which is slidably disposed on the upper part of the slide rail mechanism;

[0011] Two locking mechanisms are symmetrically arranged on the front and rear sides of the deceleration mechanism, and the two locking mechanisms are fixedly installed on the upper surface of the second support base.

[0012] Preferably, the slide rail mechanism includes multiple first vertical rails, which are equidistantly fixedly installed on the upper surface of the foundation, the upper surface of the first support seat, and the upper surface of the arc-shaped support seat. A fixed slider is slidably sleeved in the middle of each of the multiple first vertical rails. Multiple first horizontal rails perpendicular to the first vertical rails are fixedly installed on the upper surface of each fixed slider. Both the first vertical rails and the first horizontal rails are made of high-strength, corrosion-resistant material. A first square rod is fixedly installed on one side of the bottom surface of the first horizontal rail. A first threaded long rod is threadedly connected to the middle of the first square rod. A first driving component, fixedly connected to the upper surface of the first support seat, is fixedly installed at the front end of the first threaded long rod. A second square rod is fixedly installed on the other side of the bottom surface of the first horizontal rail. A second threaded long rod is threadedly connected to the middle of the second square rod. A second driving component, fixedly connected to the arc-shaped support seat, is fixedly installed at the front end of the second threaded long rod. The first and second driving components are of the same model and are connected in series in the same circuit.

[0013] Preferably, the deceleration mechanism includes multiple beam frames, which are equidistantly fixedly installed at the center of the upper surface of the second support. A second transverse rail is fixedly installed on the upper surface of the second support between adjacent beam frames. The height of each beam frame is greater than the height of the second transverse rail. A rotating seat, fixedly connected to the second support, is fixedly installed at the other end of each beam frame. The other end of the second transverse rail is fixedly connected to one side of the rotating seat. Multiple first threaded rods are equidistantly movably sleeved at the center of the rotating seat. The threads of adjacent first threaded rods have opposite directions. The multiple first threaded rods are distributed between adjacent beam frames. Between the frame and the second horizontal rail, a middle wheel is fixedly installed at the other end of each of the first threaded rods. Adjacent middle wheels mesh with each other. A threaded block is threadedly connected to the middle of each of the first threaded rods. The threaded block slides in contact with the adjacent beam frame and the second horizontal rail. A deceleration spring is fixedly installed on the side of each of the threaded blocks away from the rotary seat. The deceleration spring is made of a high-strength and high-tensile-force material. A push block is fixedly installed on the end of each of the deceleration springs away from the rotary seat. The push block slides in contact with the adjacent beam frame and the second horizontal rail.

[0014] Preferably, the front locking mechanism includes a second threaded rod, which is movably sleeved on the front side of the middle of the rotary seat. A third driving member is fixedly installed on the other side of the second threaded rod and fixedly connected to the upper surface of the second support seat. A side wheel that meshes with the adjacent middle wheel is fixedly installed on the other side of the second threaded rod. The diameter of the middle wheel is smaller than the diameter of the side wheel. A side block is threadedly connected to the middle of the second threaded rod. A telescopic mechanism that slides and engages with the second threaded rod is fixedly installed on the side of the side block away from the rotary seat.

[0015] Preferably, the telescopic mechanism includes a limiting sleeve, which is fixedly installed on the side of the side block away from the rotating seat. An elastic element is fixedly installed at the bottom of the inner cavity of the limiting sleeve, and a limiting block that slides and engages with the limiting sleeve is fixedly installed at the bottom end of the elastic element. An inclined surface is provided on the side of the limiting block away from the rotating seat.

[0016] Preferably, the bridge-carrying mechanism includes multiple sets of rollers, which are symmetrically and equally slidably fitted onto the middle of different first horizontal rails. A support plate is fixedly installed on the top of each roller. Multiple support shafts are equidistantly fitted onto the upper part of the support plate. Multiple equidistantly arranged rubber rings are fixedly installed on the curved surface of each support shaft. A baffle is fixedly installed on one side of the support plate. A top cover is movably fitted onto the upper part of the baffle. A rubber layer is provided on the lower surface of the top cover. A first mounting plate is fixedly installed on the middle of one side of the top cover. A second mounting plate is fixedly installed on the upper surface of the first mounting plate. A telescopic cylinder is fixedly installed on the middle of the side of the second mounting plate near the baffle. The telescopic end of the telescopic cylinder is fixedly installed on the middle of one side of the top cover. Multiple equidistantly arranged locking blocks are fixedly installed on the other side of the lower surface of the support plate. The multiple locking blocks are distributed in the middle of two adjacent first horizontal rails.

[0017] Preferably, the first support, the arc-shaped support, and the second support are all made of high-strength concrete.

[0018] Preferably, the deceleration spring is made of a high-strength and high-tensile metal material.

[0019] The working principle and beneficial effects of this invention are as follows:

[0020] 1. Before using this invention, the precast bridges need to be placed sequentially along one side of the beam frame, with the precast bridges placed on the upper surface of the beam frame. The starting position of the bridge-carrying mechanism is located on one side of the first horizontal rail. During use, the first and second driving components are activated simultaneously to move the first horizontal rail closer to the precast bridge. Then, the precast bridge is lifted by jacks, pushing the bridge-carrying mechanism to the other side, moving the precast bridge to the upper surface of the support shaft. Afterward, the telescopic cylinder is activated, pushing the upper cover above the precast bridge to limit its movement. Then, the first and second driving components are activated again, moving the first horizontal rail... The other end coincides with one end of the second horizontal rail corresponding to the storage area to be placed. At the same time, the first horizontal rail drives the fixed slider to slide along the first vertical rail. This enables the use of only one bridge-carrying mechanism to transport prefabricated bridges from different production areas to any storage area that does not correspond to them. This solves the problems that gantry cranes can only move in one direction, which means that when there are too many areas for production, multiple gantry cranes need to be purchased and installed, resulting in increased production costs. It also solves the problem that when the storage area corresponding to a production area is full, it cannot be directly moved to another storage area that still has space, which leads to the cessation of work in one production area and a reduction in output.

[0021] 2. This invention activates the first and second driving components simultaneously, activating the third driving component to move the telescopic mechanism to the position where the precast bridge is to be placed on the beam frame. Simultaneously, the second threaded rod sequentially drives the push block to one side via the side wheel, middle wheel, first threaded rod, threaded block, and deceleration spring. This pushes the bridge-carrying mechanism, which in turn moves the precast bridge to the other side. The bridge-carrying mechanism then causes the precast bridge to slide freely down the first horizontal rail and quickly move to the other side of the arc-shaped support. Using its own inertia and kinetic energy, it continues to slide along the second horizontal rail to the other side until the locking block contacts the push block. The locking block then pushes the push block to the other side, causing the push block to compress the deceleration spring. The deceleration spring, through the push block, reverses the movement, driving the bridge-carrying mechanism to move the precast bridge to the other side. The bridge deceleration mechanism works by pushing the precast bridge against the limiting block, causing the elastic element to contract downwards. The precast bridge moves to the other side of the limiting block, at which point it stops moving. Then, a telescopic cylinder is activated, moving the upper cover to one side and opening the top of the support plate. Simultaneously, the deceleration spring, which has been compressed, begins to reset. The deceleration spring, through a pusher block, pushes the bridge-carrying mechanism to one side. The precast bridge, positioned above the bridge-carrying mechanism, slides off the support shaft and onto the beam frame due to the limiting block's restraint. At the same time, the bridge-carrying mechanism, impacted by the deceleration spring and pusher block, returns along the rotating seat and the first horizontal rail to one side of the first horizontal rail. This allows for rapid, long-distance transport of the precast bridge to the designated storage location, avoiding the use of large gantry cranes and reducing production costs and energy consumption. It also prevents the precast bridge from falling from heights. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention provides a transportation system for the lateral movement of prefabricated bridges, including a foundation 1, wherein a pit 101 is formed on the upper surface of the foundation 1;

[0032] Multiple unidirectional guide rail mechanisms 2 are arranged at equal intervals at the bottom of the inner cavity of the foundation pit 101. The number of unidirectional guide rail mechanisms 2 is set according to the size of the actual site.

[0033] Among them, the single-direction guide rail mechanism 2 includes a first support seat 201, which is fixedly installed on one side of the bottom surface of the foundation pit 101. An arc-shaped support seat 202 fixedly connected to the bottom surface of the foundation pit 101 is fixedly installed on the other side of the first support seat 201. The height of the upper surface of one side of the arc-shaped support seat 202 is greater than the height of the upper surface of the other side, so that when the bridge-carrying mechanism 7 drives the precast bridge to slide freely from one side of the arc-shaped support seat 202 to the other side of the arc-shaped support seat 202, it can still maintain its inertia and kinetic energy and slide from one side of the second horizontal rail 402 to the other side of the second horizontal rail 402. A second support seat 203 fixedly connected to the bottom surface of the foundation pit 101 is fixedly installed on the other side of the arc-shaped support seat 202.

[0034] The slide rail mechanism 3 is installed on the upper surface of the foundation 1, the first support 201 and the arc-shaped support 202;

[0035] The deceleration mechanism 4 is located on the upper surface of the second support 203. The first support 201, the arc-shaped support 202, and the second support 203 are all made of high-strength concrete material, thereby preventing the slide rail mechanism 3 and the deceleration mechanism 4 from directly contacting the soft foundation 1. This provides a solid and stable support surface for the slide rail mechanism 3 and the deceleration mechanism 4, and prevents the slide rail mechanism 3 and the deceleration mechanism 4 from bearing excessive weight, which could cause their bottoms to bend and deform.

[0036] The bridge-carrying mechanism 7 is slidably disposed on the upper part of the slide rail mechanism 3;

[0037] Two locking mechanisms 5 are symmetrically arranged on the front and rear sides of the deceleration mechanism 4, and the two locking mechanisms 5 are fixedly installed on the upper surface of the second support 203.

[0038] like Figures 1 to 3As shown, the slide rail mechanism 3 includes multiple first vertical rails 301, which are equidistantly fixed on the upper surface of the foundation 1, the upper surface of the first support 201, and the upper surface of the arc-shaped support 202. By providing multiple first vertical rails 301, the bearing area between the first vertical rails 301 and the upper surfaces of the foundation 1 and the arc-shaped support 202 can be increased, preventing compression and indentation at the contact points between the foundation 1, the arc-shaped support 202, and the first vertical rails 301, thus avoiding deformation and damage to the first vertical rails 301. Simultaneously, providing multiple first vertical rails 301 can effectively distribute the pressure borne by a single first vertical rail 301, reducing the strength requirements of the first vertical rails 301 and thereby reducing production costs. The middle portion of the multiple first vertical rails 301... Each vertical rail 301 is slidably sleeved with a fixed slider 302. Multiple first horizontal rails 303, perpendicular to the first vertical rail 301, are fixedly installed on the upper surface of the fixed slider 302. Both the first vertical rail 301 and the first horizontal rail 303 are made of high-strength, corrosion-resistant material to prevent excessive weight load and potential damage or deformation. This also prevents rapid corrosion from prolonged exposure to rain and sunlight, which could reduce their strength, weaken their load-bearing capacity, and cause breakage. A first square rod 304 is fixedly installed on one side of the bottom surface of the first horizontal rail 303. A first threaded long rod 305 is threadedly connected to the middle of the first square rod 304. A first threaded long rod 305 is fixedly installed at the front end of the first threaded long rod 305. A first driving component 306 is fixedly connected to the upper surface of a support base 201. A second square rod 307 is fixedly installed on the other side of the bottom surface of the first horizontal rail 303. A second threaded long rod 308 is threadedly connected to the middle of the second square rod 307. A second driving component 309, which is fixedly connected to the arc-shaped support base 202, is fixedly installed at the front end of the second threaded long rod 308. The first driving component 306 and the second driving component 309 are of the same model and are connected in series in the same circuit. This allows the first driving component 306 and the second driving component 309 to simultaneously drive the first square rod 304 and the second square rod 307 forward or backward at the same time, in the same direction, and at the same speed via the first threaded long rod 305 and the second threaded long rod 308, respectively. When the first square rod 304 and the second square rod 307 move to the rear, they drive the first horizontal rail 303, which is fixedly connected to them, to move forward or backward at the same time, in the same direction, and at the same speed. This is to prevent the first driving member 306 and the second driving member 309 from having different start times and speeds. When the first threaded long rod 305 and the second threaded long rod 308 drive the first square rod 304 and the second square rod 307 to move respectively, the first square rod 304 and the second square rod 307 will be misaligned. This will cause the first square rod 304 and the second square rod 307 to squeeze the inner cavity side of the first vertical rail 301, which is in sliding contact with them. This will cause the first vertical rail 301 to be damaged and the first horizontal rail 303, which is fixedly installed on the upper surface of the first square rod 304 and the second square rod 307, to be twisted and broken at its fixed connection.

[0039] like Figure 1 , Figure 2 , Figure 4 As shown, the deceleration mechanism 4 includes multiple beam frames 401, which are equidistantly fixedly installed at the center of the upper surface of the second support 203. A second transverse rail 402, fixedly installed on the upper surface of the second support 203, is provided between adjacent beam frames 401. The height of the beam frame 401 is greater than the height of the second transverse rail 402, thereby preventing the precast bridge placed on the beam frame 401 from contacting the second transverse rail 402, which would cause the second transverse rail 402 to deform under long-term support of the precast bridge. This would result in the subsequent bridge-carrying mechanism 7 moving along the second transverse rail 402. When sliding, the distance between two adjacent second horizontal rails 402 is the same as the distance between two adjacent first horizontal rails 303. One side cross-section of the second horizontal rail 402 has the same size and shape as one side cross-section of the first horizontal rail 303, thus enabling the bridge-carrying mechanism 7 to slide quickly and smoothly from the first horizontal rail 303 to the second horizontal rail 402. The other end of the multiple beam frames 401 is fixedly installed with a rotating seat 403 that is fixedly connected to the second support seat 203. The other end of the second horizontal rail 402 is fixedly connected to one side of the rotating seat 403. The middle part of the rotating seat 403 is equidistantly movably sleeved. There are multiple first threaded rods 405, with the threads of adjacent first threaded rods 405 having opposite directions, thus ensuring that multiple threaded blocks 406 can move to one side simultaneously. The multiple first threaded rods 405 are distributed between adjacent beam frames 401 and second transverse rails 402. A central wheel 404 is fixedly installed at the other end of each of the multiple first threaded rods 405, and adjacent central wheels 404 mesh with each other. Threaded blocks 406 are threadedly connected to the middle of each of the multiple first threaded rods 405, and the threaded blocks 406 slide in contact with the adjacent beam frames 401 and the second transverse rail 402. On the side of 406 away from the pivot 403, a deceleration spring 407 is fixedly installed, which is slidably sleeved with the adjacent first threaded rod 405. The deceleration spring 407 is made of high-strength and high-tensile metal material, so as to effectively resist the strong inertia of the bridge-carrying mechanism 7 and the precast bridge, and decelerate and stop the bridge-carrying mechanism 7 and the precast bridge. On the end of multiple deceleration springs 407 away from the pivot 403, a push block 408 is fixedly installed, which is slidably sleeved with the adjacent first threaded rod 405. The push block 408 slides in contact with the adjacent beam frame 401 and the second transverse rail 402.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, the front locking mechanism 5 includes a second threaded rod 502, which is movably sleeved on the front side of the middle part of the rotary seat 403. A third driving member 501, which is fixedly connected to the upper surface of the second support seat 203, is fixedly installed on the other side of the second threaded rod 502. A side wheel 503, which meshes with the adjacent middle wheel 404, is also fixedly installed on the other side of the second threaded rod 502. The diameter of the middle wheel 404 is smaller than the diameter of the side wheel 503, thereby enabling the third driving member 501 to drive the second threaded rod 502. 2. When rotating, the second threaded rod 502 drives the side block 504 to move to one side, the side block 504 drives the telescopic mechanism 6 to move to one side, and at the same time, the second threaded rod 502 drives the side wheel 503 to rotate, the side wheel 503 drives the middle wheel 404 to rotate, the middle wheel 404 drives the first threaded rod 405 to rotate, the first threaded rod 405 drives the threaded block 406 to move to one side, the threaded block 406 drives the deceleration spring 407 to move to one side, and the deceleration spring 407 drives the push block 408 to move to one side. Because the side... The diameter of wheel 503 is larger than that of the middle wheel 404. As the side block 504 drives the telescopic mechanism 6 to move to one side, the displacement of the push block 408 and the telescopic mechanism 6 gradually increases. This increases the ability of the push block 408 and the deceleration spring 407 to overcome the bridge-carrying mechanism 7 and the precast bridge. Thus, the resistance strength of the deceleration spring 407 can be automatically adjusted according to the different kinetic energies of the bridge-carrying mechanism 7 and the precast bridge at different positions on the second horizontal rail 402. This avoids the precast bridge near the arc-shaped support seat 202 from having too much kinetic energy and causing excessive impact on the deceleration spring 407, which could damage the deceleration spring 407. At the same time, it also avoids the precast bridge away from the arc-shaped support seat 202 from having too little kinetic energy and the deceleration spring 407 from having too much resistance strength, which could prevent the precast bridge from moving to the other side of the telescopic mechanism 6. The middle of the second threaded rod 502 is threadedly connected to the side block 504. The side block 504 away from the rotating seat 403 is fixedly installed with the telescopic mechanism 6, which is slidably sleeved with the second threaded rod 502.

[0041] like Figure 2 , Figure 4 , Figure 6 As shown, the telescopic mechanism 6 includes a limiting sleeve 601, which is fixedly installed on the side of the side block 504 away from the rotating seat 403. An elastic element 602 is fixedly installed at the bottom of the inner cavity of the limiting sleeve 601. A limiting block 603 that slides and engages with the limiting sleeve 601 is fixedly installed at the bottom end of the elastic element 602. An inclined surface is provided on the side of the limiting block 603 away from the rotating seat 403, so that when the bridge-carrying mechanism 7 drives the precast bridge to move from one side of the limiting block 603 to the other side, the precast bridge can squeeze the limiting block 603 and move downward to the interior of the limiting sleeve 601.

[0042] like Figure 2 , Figure 5As shown, the bridge-carrying mechanism 7 includes multiple sets of rollers 701, which are symmetrically and equally slidably fitted onto the middle of different first horizontal rails 303. Support plates 702 are fixedly installed on the tops of the rollers 701. Multiple support shafts 703 are equidistantly fitted onto the upper part of the support plates 702. Multiple equidistantly arranged rubber rings are fixedly installed on the curved surface of the support shafts 703 to prevent the precast bridge placed on the support shafts 703 from sliding forward or backward and detaching from the support shafts 703. A baffle 704 is fixedly installed on one side of the support plate 702. A top cover 705 is movably fitted onto the upper part of the baffle 704. The lower surface of the top cover 705 is provided with a rubber layer to improve the height of the top cover. The friction between 705 and the upper surface of the precast bridge prevents the precast bridge from slipping off the bridge-carrying mechanism 7 when the bridge-carrying mechanism 7 decelerates. A first mounting plate 706 is fixedly installed in the middle of one side of the upper cover 705. A second mounting plate 707 is fixedly installed on the upper surface of the first mounting plate 706. A telescopic cylinder 708 is fixedly installed in the middle of the side of the second mounting plate 707 near the baffle 704. The telescopic end of the telescopic cylinder 708 is fixedly installed in the middle of one side of the upper cover 705. Multiple equally spaced locking blocks 709 are fixedly installed on the other side of the lower surface of the support plate 702. The multiple locking blocks 709 are distributed in the middle of two adjacent first horizontal rails 303.

[0043] Working principle and usage process:

[0044] Before use, the bridge-carrying mechanism 7 is initially positioned on one side of the first horizontal rail 303. During use, the first driving component 306 and the second driving component 309 are simultaneously activated. The output shafts of the first driving component 306 and the second driving component 309 respectively drive the first threaded rod 305 and the second threaded rod 308 to rotate. The first threaded rod 305 and the second threaded rod 308 respectively drive the first square rod 304 and the second square rod 307 to move. The first square rod 304 and the second square rod 307 drive the first horizontal rail 303 to move to the side closest to the precast bridge. Then, the precast bridge is lifted by a jack and pushed to the other side, causing the bridge-carrying mechanism 7 to move to the upper surface of the support shaft 703. Afterwards, the telescopic cylinder 708 is activated, pushing the upper cover 705 to the top of the precast bridge. The prefabricated bridge is limited, and then the first drive component 306 and the second drive component 309 are activated again, so that the other end of the first horizontal rail 303 coincides with one end of the second horizontal rail 402 corresponding to the storage area to be placed. At the same time, the first horizontal rail 303 drives the fixed slider 302 to slide along the first vertical rail 301. This realizes that only one bridge-carrying mechanism 7 can be used to transport the prefabricated bridges from different production areas to any storage area that does not correspond to it. This solves the problems that gantry cranes can only move in one direction, which requires the purchase and installation of multiple gantry cranes when there are too many areas for production, resulting in increased production costs. It also solves the problems that when the storage area corresponding to a production area is full, it cannot be directly moved to another storage area that still has space, which leads to the cessation of work in one production area and reduced output.

[0045] Next, while starting the first drive unit 306 and the second drive unit 309, the third drive unit 501 is also started. The output shaft of the third drive unit 501 drives the second threaded rod 502 to rotate clockwise. The second threaded rod 502 drives the side block 504 to move to one side. The side block 504 drives the telescopic mechanism 6 to move to the position where the precast bridge is to be placed on the beam frame 401. At the same time, the second threaded rod 502 drives the side wheel 503 to rotate clockwise. The side wheel 503 drives the middle wheel 404 to rotate. The middle wheel 404 drives the first threaded rod 405 to rotate. 5 drives the threaded block 406 to move to one side, the threaded block 406 drives the deceleration spring 407 to move to one side, the deceleration spring 407 drives the push block 408 to move to one side, and then pushes the bridge-carrying mechanism 7. The bridge-carrying mechanism 7 drives the precast bridge to move to the other side. The bridge-carrying mechanism 7 drives the precast bridge to slide freely down the first horizontal rail 303 and quickly move to the other side of the arc-shaped support seat 202. Then, using its own inertia and kinetic energy, it continues to slide along the second horizontal rail 402 to the other side until the locking block 709 contacts the push block 408. 9. Pushing the push block 408 to the other side, the push block 408 compresses the deceleration spring 407 to contract. The deceleration spring 407, through the push block 408, pushes the bridge-carrying mechanism 7 in the opposite direction, causing the precast bridge to decelerate. The precast bridge pushes the limiting block 603 to compress the elastic element 602 downwards, and the precast bridge moves to the other side of the limiting block 603. At this time, the precast bridge stops moving. The telescopic cylinder 708 is activated, and the telescopic cylinder 708 drives the upper cover 705 to one side, causing the upper part of the support plate 702 to open. At the same time, the deceleration spring 407, which has been compressed, begins to reset. The deceleration spring 407 pushes the bridge-carrying mechanism 7 to one side via the pusher block 408. The precast bridge located above the bridge-carrying mechanism 7 is limited by the limiting block 603 and slides off the support shaft 703 onto the beam frame 401. At the same time, the bridge-carrying mechanism 7 receives the impact of the deceleration spring 407 and the pusher block 408 and returns to one side of the first horizontal rail 303 along the rotating seat 403. This achieves rapid long-distance transportation of the precast bridge to the designated storage location, avoiding the use of large gantry cranes and reducing production costs and energy consumption. It also avoids the problem of precast bridges falling from heights.
