Description

Technical Field

[0001] The utility model relates to the technical field of pouring equipment, and more specifically, to a rainproof mobile pouring trolley for prefabricated bridge concrete. Background Art

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering projects, concrete and other materials are poured into a mold to form a predetermined shape. When pouring concrete, the formwork should be cleaned of debris and the cement mortar pads and plastic pads of the steel bars should be checked to see if they are properly padded.

[0003] When operators are performing engineering work on bridges, mobile casting trolleys are often used to cast the bridges quickly and efficiently. However, most bridge engineering work sites are often open-air. If it suddenly rains during the casting construction, the existing concrete casting rainproof devices only have simple measures such as tarpaulin covering. At this time, the operator can only manually cover the undried concrete with tarpaulin, which is not only time-consuming and labor-intensive, but also inefficient. In the process of covering the tarpaulin, rainwater will still fall into the concrete, which will eventually affect the quality of the concrete. At this time, the operator will stop performing engineering work, which brings inconvenience to the operator's operation. Therefore, it needs to be improved. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 5 As shown, the utility model provides a rainproof mobile pouring trolley for prefabricated bridge concrete, comprising:

[0029] The trolley body 1 has a fixed frame 2 fixedly installed at the front of the top of the trolley body 1, a long board 3 fixedly installed at the top of the fixed frame 2, a support block 4 fixedly installed at the bottom of the long board 3, a long shaft 5 movably sleeved inside the support block 4, and a tarpaulin 6 wrapped around the outer surface of the long shaft 5;

[0030] A driving mechanism is provided in front of the bottom end of the long board 3;

[0031] The unfolding mechanism is arranged at the front and rear ends of the long axis 5;

[0032] Among them, the unfolding mechanism includes a first gear 7, the interior of the first gear 7 is fixedly sleeved with the front and rear ends of the long shaft 5, the outer surface of the first gear 7 is meshed and connected with the second gear 8, the interior of the second gear 8 is movably sleeved with an arc block 9, the top of the arc block 9 is fixedly connected to the bottom end of the long board 3, the outer surface of the second gear 8 is meshed and connected with a gear rod 10, the interior of the gear rod 10 is movably sleeved with a fixed plate 11, the top of the fixed plate 11 is fixedly connected to the bottom end of the long board 3, the interior of the other end of the gear rod 10 is movably sleeved with a moving rod 12, the outer surface of the top of the other end of the moving rod 12 is movably sleeved with a moving block 13, and the top of the moving block 13 is fixedly connected to the outer surface of the tarpaulin 6.

[0033] When the two groups of first gears 7 rotate in opposite directions, they will respectively drive the two long shafts 5 to rotate along the inside of the two groups of support blocks 4. Since the two groups of first gears 7 are meshed and connected with the two groups of second gears 8, the two groups of second gears 8 will rotate under the drive of the two groups of first gears 7. Since the two groups of second gears 8 are meshed and connected with the two groups of gear rods 10, when the two groups of second gears 8 rotate, they will drive the two groups of gear rods 10 to rotate. At the same time, the other ends of the two groups of gear rods 10 will drive the two groups of motion rods 12 to move. At this time, the outer surfaces of the top ends of the other ends of the two groups of motion rods 12 will squeeze and push the two motion blocks 13, causing the two motion blocks 13 to move away from each other. At this time, the two motion blocks 13 will unfold the two tarpaulins 6 while moving away from each other.

[0034] The driving mechanism includes:

[0035] A fixed block 14, the top of which is fixedly connected to the bottom of the long board 3, a dual-axis motor 15 is fixedly sleeved inside the fixed block 14, and a rotating shaft 16 is fixedly sleeved on the other end of the output shaft of the dual-axis motor 15;

[0036] The bevel gear 17 has an interior that is fixedly sleeved with the outer surface of the rotating shaft 16 , and an outer surface of the bevel gear 17 that is meshed with the outer surface of the first gear 7 .

[0037] When the dual-axis motor 15 is running, the two rotating shafts 16 will drive the two bevel gears 17 to rotate in opposite directions. Since the two bevel gears 17 are meshed with the two first gears 7, when the two bevel gears 17 rotate in opposite directions, they will drive the two first gears 7 to rotate in opposite directions.

[0038] A limiting groove 18 is provided at the top of the long board 3 , and a top cover 19 is fixedly installed at the top of the long board 3 .

[0039] Due to the design of the limiting groove 18, the object located therein will be limited so that it can only move forward and backward.

[0040] A material barrel 20 is fixedly mounted on the top of the trolley body 1 , and a material feed port 30 is fixedly mounted on the top of the material barrel 20 .

[0041] Due to the design of the feed port 30 , an operator can fill concrete into the interior of the bucket 20 through the feed port 30 .

[0042] Among them, a suction pipe 21 is fixedly sleeved inside the top of the material barrel 20, a delivery pipe 22 is fixedly installed on the top of the suction pipe 21, a pump 23 is fixedly installed on the right side of the delivery pipe 22, and a bracket 31 is fixedly installed on the bottom end of the pump 23, and the bottom end of the bracket 31 is fixedly connected to the top of the trolley body 1.

[0043] When the pump 23 is running, the suction pipe 21 will suck the concrete inside the barrel 20 , and then the concrete will move to the inside of the delivery pipe 22 through the suction pipe 21 .

[0044] The outer surface of the left end of the feeding pipe 22 is movably connected to the discharge pipe 24 , and a rack 25 is fixedly installed on the top of the discharge pipe 24 . The outer surface of the rack 25 is movably connected to the inside of the limiting groove 18 .

[0045] When the concrete inside the suction pipe 21 moves into the delivery pipe 22, the concrete inside the delivery pipe 22 will be discharged through the discharge pipe 24, so that the pouring operation can be carried out. Since the inside of the discharge pipe 24 is movably connected to the outer surface of the delivery pipe 22, the discharge pipe 24 can move back and forth along the outer surface of the delivery pipe 22.

[0046] Among them, an arc-shaped plate 26 is fixedly installed on the top of the long board 3, and a driving motor 27 is fixedly installed on the front of the arc-shaped plate 26. The other end of the output shaft of the driving motor 27 is fixedly sleeved with a rotating shaft 28, and the other end of the rotating shaft 28 is fixedly sleeved with a driving gear 29. The outer surface of the driving gear 29 is meshed with the top of the rack 25.

[0047] When the drive motor 27 is running, the rotating shaft 28 will drive the drive gear 29 to rotate. Since the drive gear 29 is meshed with the rack 25, the drive gear 29 will drive the rack 25 to move during rotation. Due to the limitation of the limiting groove 18, the rack 25 will move forward along the inside of the limiting groove 18 driven by the drive gear 29. At the same time, the discharge pipe 24 will move forward driven by the rack 25.

[0048] The working principle and use process of this utility model:

[0049] When it rains while the operator is carrying out construction work on the bridge, the operator starts the dual-axis motor 15. At this time, the two rotating shafts 16 will respectively drive the two bevel gears 17 to rotate in opposite directions. Since the two bevel gears 17 are respectively engaged with the two groups of first gears 7, the two groups of first gears 7 will rotate under the drive of the two bevel gears 17. Then the two groups of first gears 7 will respectively drive the two long shafts 5 to rotate with the movable sockets with the two groups of support blocks 4 as the axis. At this time, the two long shafts 5 will unwind the two tarpaulins 6 during rotation. Since the two groups of first gears 7 are respectively engaged with the two groups of second gears 8, the two groups of first gears 7 will drive the two groups of second gears 8 to rotate with the two groups of arc blocks 9 during rotation. The movable socket is rotated as the axis, and since the two groups of second gears 8 are respectively engaged with the two groups of gear rods 10, the two groups of gear rods 10 will rotate with the movable socket with the two groups of fixed plates 11 as the axis under the drive of the two groups of second gears 8. At this time, the other ends of the two groups of gear rods 10 will squeeze and push the two groups of motion rods 12 respectively. At the same time, the outer surfaces of the top ends of the other ends of the two groups of motion rods 12 will squeeze and push the two motion blocks 13 respectively, so that the two motion blocks 13 move back to back. At this time, the two motion blocks 13 will unfold the two tarpaulins 6 in the back-to-back movement. At this time, the two tarpaulins 6 will have a good rainproof effect on the concrete, thereby realizing the function of automatically unfolding and retracting the tarpaulins 6 according to usage needs.

[0050] When the operator needs to cast molds of different sizes, the operator starts the drive motor 27, and the rotating shaft 28 will drive the drive gear 29 to rotate. Since the outer surface of the drive gear 29 is meshed with the outer surface of the top of the rack 25, when the drive gear 29 rotates, it will drive the rack 25 to move. Due to the design of the limit groove 18, the movement of the rack 25 will be limited so that it can only move forward and backward. At this time, the rack 25 will move forward along the inside of the limit groove 18 driven by the drive gear 29. At the same time, the rack 25 will drive the discharge pipe 24 to move forward along the outer surface of the delivery pipe 22, thereby realizing the function of extending and retracting the discharge pipe 24 according to the size of the mold.
