Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to concrete curing equipment for construction engineering. Background Art

[0002] Concrete buildings need to be cured after pouring so that the concrete can reach its designed strength. The common curing method is to spray special curing liquid on the surface of the concrete structure and cover it with a polymer film to achieve a certain degree of sealing and moisture retention. Under the combined action of water and other components in the liquid, the microscopic crystal structure of the concrete undergoes certain changes, achieving higher mechanical properties.

[0003] Concrete structures of different shapes require different film laying and covering methods. Concrete load-bearing columns are often covered in a winding manner, such as CN117027459A concrete building maintenance equipment. When the equipment is working, the device needs to be installed on the outside of the concrete structure first, and then it needs to be dismantled after the operation is completed. It is not convenient to use. For example, CN118441908A is a concrete maintenance device for construction. This equipment does not need to be installed on the concrete structure, but because it has its own lifting bracket, it is large in size and difficult to move at the construction site.

[0004] In addition, most of the devices in this field, including the above-mentioned equipment, are equipped with a mechanism for winding a rotating film roll. During the winding process, the film will generate a tangential tension on the film roll, causing the film roll to slightly rotate. In this state, the film cannot maintain sufficient tension and cannot remain taut when wound around the concrete structure. Gaps are generated between the films, causing water to be lost too quickly in the concrete structure, resulting in a maintenance effect that is difficult to achieve the expected.

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0037] Combined with Figure 1 , Attachment Figure 2 and attached Figure 7 A concrete curing equipment for construction engineering comprises a rotating base 1, a rotating support arm 5 and a film reel 7. The top and bottom of the rotating base 1 are both hingedly provided with swing arms 2. The bottom of the rotating base 1 is hingedly connected to a lifting hydraulic cylinder 6. The free end of the lifting hydraulic cylinder 6 is hingedly connected to the bottom of the swing arm 2. The end of the swing arm 2 is hingedly provided with a mounting rod 3. The mounting rod 3 is rotatably connected to an extension arm 4. The end of the extension arm 4 is rotatably connected to the rotating support arm 5. The end of the rotating support arm 5 is provided with a flippable sliding rod 22. The film reel 7 is slidably sleeved on the sliding rod 22.

[0038] The rotating base 1 is arranged on an engineering vehicle equipped with a hydraulic pump station, and the hydraulic oil required for the operation of each hydraulic power component of the device and the electric power required for the motor are all provided by the engineering vehicle.

[0039] Combined with Figure 4 and attached Figure 5The mounting rod 3 is provided with a first hydraulic motor 11, which drives the extension arm 4 to rotate. A second hydraulic motor 13 is provided at the end of the extension arm 4, which drives the rotating support arm 5 to rotate. A first hydraulic oil slip ring 10 is provided at the connection between the extension arm 4 and the first hydraulic motor 11, and a second hydraulic oil slip ring 12 is provided at the connection between the rotating support arm 5 and the second hydraulic motor 13. In addition to providing a rotating connection for the hydraulic oil circuit, the above-mentioned first hydraulic oil slip ring 10 and the second hydraulic oil slip ring 12 also provide a rotating connection for the power supply and control circuit. This type of device belongs to the prior art and is not further described in this application.

[0040] Reference Figure 3 When the device is implemented, the engineering vehicle must first be driven to the vicinity of the columnar concrete structure 9. First, the extension arm 4 is controlled to rotate toward the side of the engineering vehicle so that the rotating arm 5 extends to the outside of the vehicle. The lifting hydraulic cylinder 6 is controlled to lift the swing arm 2. The height of the mounting rod 3 continues to rise and stops lifting when the bottom surface of the rotating arm 5 is higher than the top of the concrete structure 9. The rotation angle of the rotating base 1 and the extension arm 4 is controlled so that the rotation axis of the rotating arm 5 is roughly aligned with the geometric axis of the concrete structure 9. The sliding rod 22 is controlled to flip downward until it is parallel to the geometric axis of the concrete structure 9. The rotating arm 5 is controlled to rotate around the concrete structure 9. During this process, the film roll 8 is continuously wound around the surface of the concrete structure 9. The film roll 7 is controlled to continuously descend along the sliding rod 22 to wrap the film at different heights of the concrete structure 9.

[0041] When the film roll 8 is wrapped around the concrete structure 9, a pulling force is applied to the film roll 7 along its tangential direction, causing the film roll 7 to rotate. After the film roll 7 rotates a certain angle, the film roll 8 cannot be wrapped around the surface of the concrete structure 9 in a taut state, which will cause the internal moisture of the concrete structure 9 to be lost prematurely during the maintenance process, making it difficult for the final strength of the concrete structure 9 to reach the expected level.

[0042] Combined with Fig.10 , Attachment Fig.11 , Attachment Fig.12 , Attachment Fig.13 and attached Fig.14A flip platform 20 is hingedly set at the end of the rotating arm 5, and the top of the sliding rod 22 is rotatably connected to the flip platform 20. A shaft damper 30 is set on the top of the flip platform 20. The interior of the shaft damper 30 is set to be hollow and filled with hydraulic oil. A separating ring 39 is provided in the center to separate the interior of the shaft damper 30 into a first chamber 36 below and a second chamber 37 above. A pump wheel 32 is rotatably set in the first chamber 36, and a docking flange 35 is provided at the bottom of the pump wheel 32 to be connected to the top of the sliding rod 22. A pitch adjustment disk 31 and a plurality of guide blades 40 are rotatably set in the second chamber 37. A reflux chamber 38 is provided around the edge of the separating ring 39 to connect the first chamber 36 with the edge of the second chamber 37, and a reflux hole 43 is provided in the center of the separating ring 39 to connect the first chamber 36 with the center of the second chamber 37.

[0043] Since the film roll 7 is sleeved on the sliding rod 22, the rotating shaft damper 30 applies a damping to the sliding rod 22 to resist the rotation of the film roll 7, thereby reducing the degree of rotation of the film roll 7 caused by the tension of the film roll 8, so that the film roll 8 can be tightly attached to the surface of the concrete structure 9.

[0044] The rotation of the film reel 7 drives the sliding rod 22 to rotate in the same direction, so that the pump wheel 32 rotates in the first chamber 36. The pump wheel 32 is provided with a plurality of pump wheel blades 44 pointing to its axis. The rotating pump wheel blades 44 suck the hydraulic oil through the reflux hole 43 and discharge it into the reflux chamber 38. The hydraulic oil passes through the reflux chamber 38 to the second chamber 37 and returns to the reflux hole 43 through the gap between the guide blades 40 and repeats the above cycle.

[0045] Combined with Fig.11 , Attachment Fig.12 and attached Fig.13 The bottom of the flow-facing end of the guide blade 40 is rotatably connected to the upper surface of the separation ring 39, a limit slide 41 is provided above the middle of the guide blade 40, and the pitch adjustment disk 31 is provided with a plurality of limit slide grooves 42 that cooperate with the limit slide 41. The top of the shaft damper 30 is provided with a pitch adjustment motor 34 and a reducer 33, and the input end of the reducer 33 is connected to the pitch adjustment motor 34 for power, and the output end is connected to the pitch adjustment disk 31 for power.

[0046] The rotating adjustable distance disk 31 can synchronously adjust the angles of multiple guide blades 40. When the direction of the guide blades 40 is parallel to the radial direction of the second chamber 37, the flow cross-sectional area formed by the gaps between the multiple guide blades 40 is the largest. In this state, the circulation resistance of the hydraulic oil is the smallest. When there is an angle between the direction of the guide blades 40 and the radial direction of the second chamber 37, as the angle between the two increases, the flow cross-sectional area continues to decrease, which increases the circulation resistance of the hydraulic oil. By adjusting the angle of the rotating adjustable distance disk 31, the flow resistance of the hydraulic oil inside the shaft damper 30 can be changed, thereby generating damping to resist the rotation of the sliding rod 22 and reducing the rotation angle of the film reel 7.

[0047] Combined with Figure 6 The rotating arm 5 is slidably connected to a force measuring slider 14, a force sensor 16 is provided at the top of the rotating arm 5, the force sensor 16 detects the horizontal force between the rotating arm 5 and the force measuring slider 14, coil springs 17 are provided on both sides of the sliding direction of the force measuring slider 14, the coil spring 17 is connected to the rotating arm 5, the top of the force measuring slider 14 is rotatably connected to the end of the extension arm 4, the other end of the connection between the extension arm 4 and the sliding rod 22 is provided with a counterweight 15, the counterweight 15 is used to balance the centrifugal effect of each component at the other end of the extension arm 4 during rotation, so that the rotating arm 5 is subjected to balanced force during rotation.

[0048] The above mechanism can be used to detect in real time the radial component of the tension generated by the film roll 8 on the film roll drum 7 in the rotating circle of the rotating support arm 5, which can be used to indicate the tightness of the film roll 8. The tension borne by the film roll 8 is judged by the degree of the force sensor 16 to adjust the rotation angle of the rotating distance adjusting disk 31 in real time, ensuring that the film roll 8 can fit tightly to the surface of the concrete structure 9 while avoiding excessive force on it that causes tearing.

[0049] Combined with Figure 7 A flip adjustment slider 19 is slidably arranged near the end of the rotating support arm 5 , and a first connecting rod 21 is hingedly arranged on both sides of the flip adjustment slider 19 , and the end of the first connecting rod 21 is hingedly connected to the bottom of the flip platform 20 .

[0050] Combined with Figure 8 A lifting adjustment slider 23 is slidably arranged at the bottom of the rotating arm 5, and is rotatably connected to a screw 24 that drives the lifting adjustment slider 23 to move. Second connecting rods 26 are hingedly arranged on both sides of the lifting adjustment slider 23. A slip ring hinge block 27 is rotatably connected to the top of the film roll 7. The end of the second connecting rod 26 is hingedly connected to the slip ring hinge block 27. A flip adjustment hydraulic cylinder 18 is arranged on both sides of the rotating arm 5. The power end of the flip adjustment hydraulic cylinder 18 is connected to the flip adjustment slider 19. A lifting adjustment motor 25 is arranged at the bottom of the rotating arm 5. The power end of the lifting adjustment motor 25 is power-connected to the screw 24.

[0051] In the above-mentioned mechanism, the flipping adjustment slider 19 controls the flipping of the sliding rod 22, and the lifting adjustment slider 23 controls the lifting and lowering of the film roll 7. When the sliding rod 22 flips, the film roll 7 will rotate with it. When the hinge axis of the slip ring hinge block 27 and the second connecting rod 26 is not colinear with the hinge axis of the rotating arm 5 and the flipping platform 20, the flipping adjustment hydraulic cylinder 18 drives the lifting adjustment slider 23 to move through the second connecting rod 26 during operation. Since the threaded cooperation between the screw 24 and the lifting adjustment slider 23 has a certain self-locking effect, it will interfere with the operation of the flipping adjustment hydraulic cylinder 18.

[0052] Combined with Fig. 9 and attached Fig.10 A Hall sensor 28 is provided inside the hinge of the rotating arm 5 and the flip platform 20, and a permanent magnet 29 cooperating with the Hall sensor 28 is provided at the hinge of the second connecting rod 26 and the slip ring hinge block 27. When the distance between the Hall sensor 28 and the permanent magnet 29 is minimum, the hinge of the rotating arm 5 and the flip platform 20 is coaxial with the hinge of the second connecting rod 26 and the slip ring hinge block 27.

[0053] As attached Fig. 9 As shown, the hinge between the slip ring articulated block 27 and the second connecting rod 26 extends outward. When the film roll 7 is displaced to the root of the sliding rod 22, the articulated shaft of the slip ring articulated block 27 and the second connecting rod 26 is coaxial with the articulated shaft of the rotating arm 5 and the flipping platform 20. In this state, the film roll 7 and the sliding rod 22 rotate around the same axis. The film roll 7 cannot drive the lifting adjustment slider 23 by driving the second connecting rod 26. The flipping adjustment hydraulic cylinder 18 can drive the sliding rod 22 to flip normally through the flipping adjustment slider 19. The Hall sensor 28 detects the distance between itself and the permanent magnet 29 in real time. When the distance is detected to be the smallest, it means that the articulated shaft of the slip ring articulated block 27 and the second connecting rod 26 is coaxial with the articulated shaft of the rotating arm 5 and the flipping platform 20.

[0054] The present invention and its implementation methods are described above, and such description is not restrictive, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by it, and does not deviate from the purpose of the invention, and does not creatively design a structure and implementation method similar to the technical solution, they should all fall within the protection scope of the present invention.
