DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figure 1-15 As shown, a material transport device for bridge construction includes a mobile frame 1 and a track mechanism 2; the track mechanism 2 includes a support cover 20 and a connecting rod 21, and two support covers 20 are provided, and the two support covers 20 are fixedly connected by the connecting rod 21; the two support covers 20 are respectively placed on the crash barriers 112 on both sides of the bridge. The support cover 20 is provided with a lifting support wheel assembly 22 and a support track 23. The lifting support wheel assembly 22 can drive the support cover 20 and the support track 23 to move along the crash barrier 112.

[0024] The lifting support wheel assembly 22 includes a connecting seat 220 and a lifting cylinder 221. The connecting seat 220 is slidably connected to the support cover 20, and the two ends of the lifting cylinder 221 are fixedly connected to the connecting seat 220 and the support cover 20 respectively. A first driving rail wheel 222 is provided on the connecting seat 220; the lifting cylinder 221 is extended to make the first driving rail wheel 222 contact the anti-collision wall 112, and the support cover 20 can be driven to move along the anti-collision wall 112 by the first driving rail wheel 222. A second driving rail wheel 10 that cooperates with the support rail 23 is provided at the lower end of the mobile frame 1. Both the first driving rail wheel 222 and the second driving rail wheel 10 are electric rail wheels.

[0025] A first moving vehicle 11 and two second moving vehicles 12 that move along the moving vehicle 1 are provided on the moving frame 1, and a corresponding connecting track 13 is provided on the moving frame 1. The first moving vehicle 11 is located between the two second moving vehicles 12; a material hopper 14 is fixed on the first moving vehicle 11, and a blocking mechanism 15 is provided at the discharge port of the material hopper 14. The second moving vehicle 12 is connected to a support plate 17 through a support cylinder 16, and a through groove 200 that cooperates with the support plate 17 is provided on the support cover 20; a baffle 18 is fixedly connected to the support plate 17.

[0026] The working principle of the device is as follows: the second driving rail wheel 10 drives the mobile frame 1 to move along the support rail 23, so that the material can be transported longitudinally; the first mobile vehicle 11 moves along the mobile frame 1, so that the material can be transported transversely. After the material hopper 14 on the first mobile vehicle 11 is transported to the required pouring point through the above movement, the blocking mechanism 15 is controlled to open, so that the concrete material in the material hopper 14 is discharged. At the same time, the baffles 18 on the two second mobile vehicles 12 are used to block the two sides of the wet joint, so as to avoid the material from spilling.

[0027] When it is necessary to move to the next area for pouring, the two second moving vehicles 12 move to both sides and are respectively located above the corresponding anti-collision walls 112. Then, the support cylinder 16 is extended to allow the end of the support plate 17 to pass through the through slot 200 and contact the anti-collision wall 112; the support cylinder 16 continues to extend until the moving frame 1 is lifted up, so that there is a movable gap between the moving frame 1 and the upper part of the support cover 20.

[0028] When there is an active interval, the lifting cylinder 221 is retracted to make the first driving rail wheel 222 contact the anti-collision wall 112; then the first driving rail wheel 222 drives the support cover 20 to move along the anti-collision wall 112, thereby changing the position of the support cover 20. When the support cover 20 moves to the next pouring area; the lifting cylinder 221 is extended to make the support cover 20 move down and support on the anti-collision wall 112. The support cylinder 16 is retracted to make the mobile frame 1 descend until the second driving rail wheel 10 cooperates with the support rail 23; then the material bucket 14 on the first mobile vehicle 11 is transported to the required pouring point to continue pouring.

[0029] Furthermore, the blocking mechanism 15 includes a blocking plate 150 and a driving mechanism. Two blocking plates 150 are provided. The two blocking plates 150 are arranged opposite to each other and are both rotatably connected to the material hopper 14. The discharge port of the material hopper 14 is blocked by the two blocking plates 150. The two blocking plates 150 are both provided with a connecting gear 151, and the two connecting gears 151 are meshed with each other. When any connecting gear 151 rotates, the two blocking plates 150 can be driven to rotate and open and close.

[0030] The driving mechanism includes a driving rod 152 and a driving gear 153. The driving gear 153 is coaxially fixedly connected to one of the connecting gears 151. A support rod 154 is fixed on the material hopper 14. The driving rod 152 is slidably connected to the support rod 154. A first return spring 155 is provided between the support rod 154 and the driving rod 152. When the driving rod 152 moves downward, the first return spring 155 is compressed to generate elastic potential energy.

[0031] A driving rack 156 meshing with the driving gear 153 is fixedly connected to the upper end of the driving rod 152; a pushing mechanism 3 is provided on the baffle 18 of one of the second moving vehicles 12, and the driving rod 152 is driven to move by the pushing mechanism 3.

[0032] After moving to the pouring point, the driving rod 152 is driven downward by the pushing mechanism 3, so that the driving rack 156 gradually meshes with the driving gear 153 and drives the corresponding connecting gear 151 to rotate, so that the blocking plate 150 is opened; the concrete material in the material hopper 14 is discharged through the discharge port. After the pouring is completed, the driving rod 152 is driven upward by the pushing mechanism 3, so that the driving rack 156 meshes with the driving gear 153 and drives the corresponding connecting gear 151 to rotate in the opposite direction, so that the blocking plate 150 is closed.

[0033] Further, the pushing mechanism 3 includes a card plate 30, a support arm 31 and a pushing cylinder 32. The support arm 31 is fixedly connected to the baffle 18, the card plate 30 is slidably connected to the support arm 31, and the two ends of the pushing cylinder 32 are fixedly connected to the card plate 30 and the support arm 31 respectively; a driving plate 33 plugged with the card plate 30 is fixed on the driving rod 152. The card plate 30 is plugged with the driving rod 152 by moving the second moving vehicle 12 provided with the pushing mechanism 3. The blocking plate 150 can be opened by extending the pushing cylinder 32 to drive the card plate 30 and the driving plate 33 to move downward; conversely, the blocking plate 150 can be closed by retracting the pushing cylinder 32 to drive the card plate 30 and the driving plate 33 to move upward (the first return spring 155 releases the elastic potential energy).

[0034] Furthermore, the pushing mechanism 3 further includes a vibrating rod 34, which is fixedly connected to the clamping plate 30 through a fixing plate 35. When the pushing cylinder 32 extends to drive the clamping plate 30 to move downward, the vibrating rod 34 is also driven to move downward accordingly, thereby extending into the pouring point to perform a vibrating operation during the pouring process.

[0035] Furthermore, a second return spring 157 is provided between the two blocking plates 150; the second return spring 157 is preferably a tension spring; after the two blocking plates 150 are opened, the tension spring is stretched. The two ends of the tension spring are respectively hinged to the corresponding blocking plates 150. Both blocking plates 150 are provided with plug plates 158, and the two plug plates 158 are staggered up and down.

[0036] When the two blocking plates 150 are closed, the driving rod 152 continues to move upward, so that the plugging shaft 159 on it is plugged into the two plugging plates 158 arranged staggered up and down. Through this structural setting, the plugging shaft 159 can limit the opening of the two blocking plates 150, thereby preventing the two blocking plates 150 from opening accidentally.

[0037] Furthermore, a third driving rail wheel 19 is provided on the second moving vehicle 12; and a supporting rail wheel 110 is provided on the first moving vehicle 11. The third driving rail wheel 19 can also be an electric rail wheel, and the supporting rail wheel 110 can be a common rail wheel, which does not have a power source drive. That is, the movement of the first moving vehicle 11 is achieved by the push of the second moving vehicle 12. For example: when the first moving vehicle 11 needs to move to the left, the second moving vehicle 12 on the left side moves to the left, and the second moving vehicle 12 on the right side also moves to the left and contacts with the first moving vehicle 11, pushing the first moving vehicle 11 to move to the left accordingly.

[0038] Furthermore, in order to prevent the first moving vehicle 11 from moving at will, an articulated seat 111 is fixed on the first moving vehicle 11, and a limit claw 4 is hinged on the articulated seat 111; a third return spring 5 is provided between the limit claw 4 and the first moving vehicle 11; and a limit rack 6 connected to the limit claw 4 is fixedly connected to the moving frame 1. In the initial state, the limit claw 4 is pushed to rotate and engage with the limit rack 6 by the third return spring 5.

[0039] When the first moving vehicle 11 needs to move, the second moving vehicle 12 gradually approaches the first moving vehicle 11 until the push rod 7 on the second moving vehicle 12 cooperates with the limiting claw 4 to lift the limiting claw 4 and separate it from the limiting rack 6. At this time, the second moving vehicle 12 can contact the first moving vehicle 11 and drive the first moving vehicle 11 to move.

[0040] Further, a top shaft 8 is fixedly connected to the limit claw 4, and a front end of the top rod 7 is provided with an inclined surface matching the top shaft 8. When the second moving vehicle 12 approaches the first moving vehicle 11, the front end inclined surface of the top rod 7 gradually contacts the top shaft 8, thereby lifting the limit claw 4.

[0041] Furthermore, both second moving vehicles 12 are provided with a push rod 7 for driving the limit claw 4 to rotate, and both push rods 7 are provided with slots 70 and the two slots 70 are staggered. With this structural arrangement, even when both second moving vehicles 12 are in contact with the first moving vehicle 11, the two push rods 7 will not interfere with each other.

[0042] Furthermore, in order to improve the fixing effect, a clamping mechanism 9 is provided on the support cover 20, and the clamping mechanism 9 includes a clamping plate 90 and a clamping cylinder 91; the cylinder body of the clamping cylinder 91 is fixedly connected to the support cover 20, and the clamping plate 90 is hinged to the piston rod of the clamping cylinder 91. When the support cover 20 moves, the clamping cylinder 91 is extended to make the clamping plate 90 contact with the anti-collision wall 112, thereby playing the role of fixing the support cover 20. Conversely, when the support cover 20 needs to move, the clamping cylinder 91 is retracted to make the clamping plate 90 not contact with the anti-collision wall 112.

[0043] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
