Description

Technical Field

[0001] The invention belongs to a construction method for turning over a component, and specifically relates to a device and a process for slowly turning over a component by pushing the component to cause a certain displacement and thus changing its posture in the air and utilizing its own weight. Background Art

[0002] There are generally two techniques for turning over components: double-machine lifting and turning over, and bottom-mouth rotation turning over. Among them, double-machine lifting is generally used for more fragile components, and generally turns over from a horizontal position to a vertical position. If it is to turn over from a vertical position to a horizontal position, the wire rope of the lifting equipment needs to have an inclination angle, which is a very dangerous operation for the lifting equipment. At the same time, for the components, this turning over action is very uncontrollable and has a high risk factor. Bottom-mouth rotation turning over is used when the bottom of the component is strong and can provide sufficient support for rotation, and this process is generally suitable for turning over from a horizontal position to a vertical position. The existing technology currently does not have a flipping construction from a vertical to a horizontal position. There are also the following major problems in flipping existing components with fragile structures underneath: when there are sensitive structures underneath the components, the components need to be raised to prevent the sensitive structures from contacting the rotation point or the ground, and the bottom of the components need to be protected. Specifically, when the components are flipped while being lifted by a lifting device, it is necessary to ensure that the bottom of the components is 50-100 cm from the ground, and the rotation point must be 50-100 cm away from the bottom to effectively protect the sensitive structure. If the protection distance is too large, the components are prone to overturning during the flipping process. Summary of the invention

[0003] The purpose of the present invention is to provide a push-type component turning device and construction method from a vertical flat component, which can solve the problem of having sensitive structures under the component, by pushing the bottom to make the component turn a certain angle, and then use gravity to rotate around the pushing point to achieve the component turning operation.

[0004] The technical solution adopted by the present invention to solve this technical problem is: a push-type construction device for turning over a vertically flat component, comprising: Lifting equipment, which is used to lift the components to be turned over; A rotating reaction member, which is installed on the component to be turned over; The sliding bracket comprises a sliding groove and a sliding member; the rotating reaction member is placed on the sliding member, and the sliding member slides in the sliding groove, thereby driving the member to be turned over to rotate; The supporting bracket is arranged on one side of the sliding bracket and is used for supporting the component after turning over.

[0005] As a further solution of the present invention, a hanging point is installed on the upper part of the component to be turned over.

[0006] As a further solution of the present invention, a connecting piece is pre-buried in the component to be turned over, the rotation reaction piece is fixed to the connecting piece by welding, and the bottom of the rotation reaction piece has a concave arc-shaped saddle.

[0007] As a further solution of the present invention, the sliding bracket further comprises a propulsion jack and a reaction seat; the sliding member comprises a support structure and a rotating steel pipe; The support structure is slidably arranged in the slide groove, the rotating steel pipe is fixed to the top of the support structure, the propulsion jack is fixed through a reaction seat, and the propulsion jack is used to drive the support structure to move in the slide groove.

[0008] As a further solution of the present invention, the slide chute includes a main beam, a limit plate and a slide plate; an inverted L-shaped limit plate is fixed on both sides along the length direction of the main beam, and a slide plate is fixed on the top of the main beam.

[0009] As a further solution of the present invention, there are multiple supporting brackets.

[0010] The present invention also provides a construction method using the construction device, comprising the following steps: S1. Install a fixed support bracket, adjust the sliding member to the initial position of the slide slot, and install a rotating reaction member on the member to be turned over; S2. After the lifting equipment is in place, the component to be turned over is transported to the turning operation area. The lifting equipment lifts the hanging point of the component to be turned over, and the rotating reaction piece of the rotating surface is pressed against the rotating steel pipe of the sliding bracket to prepare for the turning operation; S3. The propulsion cylinder of the sliding bracket is slowly pushed forward, and the hanging point remains vertical and motionless until the distance between the center of gravity of the component and the rotating hinge is Δ≥30cm. Then, the sliding part is locked, and the propulsion cylinder stops supplying oil to maintain the extended length; S4. The boom of the lifting equipment rotates slowly, and the upper hanging point is controlled to rotate slowly around the rotating hinge point; S5, continue to execute step S4 until the component is turned over; S6. Lift the component that has been turned from vertical to horizontal, tighten the propulsion cylinder to its initial state, and prepare for the next component turning operation.

The construction method has two major innovations. One is to use a sliding bracket to provide the initial displacement of the turning structure and provide a subsequent rotation support hinge; the other is to balance gravity and the lifting force of the lifting equipment to achieve a safe vertical flat turning.

DETAILED DESCRIPTION

[0017] The present invention is described in detail and completely below in conjunction with the accompanying drawings. A person of ordinary skill in the art will be able to implement the present invention based on these descriptions. Before describing the present invention in conjunction with the accompanying drawings, it should be particularly pointed out that the technical solutions and technical features provided in each part of the present invention, including the following description, can be combined with each other without conflict.

[0018] In addition, the embodiments of the present invention involved in the following description are generally only a part of the embodiments of the present invention, rather than all the embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and implementations, and its specific implementation process is as follows: Example: like Figure 1 As shown, the present invention provides a push-type construction device for turning over a vertically flat member, comprising: A lifting device 1 is used for lifting a component 3 to be turned over. In this embodiment, the bottom of the component 3 to be turned over has a sensitive structure 4; A rotating reaction member 5, which is installed on the component to be turned over 3, and in this embodiment, it is installed on the rotating surface of the component to be turned over 3; The sliding bracket comprises a slide groove 6 and a sliding member 7; the rotation reaction member 5 is placed on the sliding member 7, and the sliding member 7 slides in the slide groove 6, thereby driving the member to be turned over 3 to rotate; The support bracket 8 is arranged on one side of the sliding bracket and is used to support the component after turning over; the bottom of the support bracket 8 is fixed to ensure that the support bracket 8 does not move.

[0020] In a preferred embodiment of the present application, a hanging point 2 is installed on the upper part of the component 3 to be turned over.

[0021] In a preferred embodiment of the present application, Figure 5 As shown, a connecting piece is embedded in the component 3 to be turned over, and the rotating reaction piece 5 is welded and fixed to the connecting piece. The connecting piece in this embodiment is a steel bar 31, and the bottom of the rotating reaction piece 5 has a concave arc-shaped saddle 51 for accommodating a rotating steel pipe 72, so as to facilitate the rotation of the component 3 to be turned over around the rotating steel pipe 72.

[0022] In a preferred embodiment of the present application, Figure 2~3 As shown, the sliding bracket further includes a propulsion jack 91 and a reaction seat 92; the sliding member 7 includes: a support structure 71 and a rotating steel pipe 72; The support structure 71 is slidably arranged in the slide 6, and the rotating steel pipe 72 is welded and fixed to the top of the support structure 71 to ensure the rotation of the component. When the component 3 to be turned over is hoisted above the construction device, the upper part of the rotating steel pipe 72 is located in the arc-shaped saddle 51, and the propulsion jack 91 is fixed by the reaction seat 92. The propulsion jack 91 is used to drive the support structure 71 to move in the slide 6. In this embodiment, the two ends of the propulsion jack 91 are respectively fixed to the support structure 71 and the reaction seat 92 through the connecting ear plate 74. The support structure 71 is welded into an H-shaped structure by steel, and the bottom of the steel is welded with a sliding bottom plate 73 for sliding in the slide 6.

[0023] The rotating reaction member 5 is set on the component 3 to be turned over. The rotating reaction member 5 and the rotating steel pipe 72 work together to realize the rotation of the component 3 to be turned over. Since the rotating steel pipe 72 has a certain height, the propulsion force of the propulsion jack 91 and the component reaction force are not in a straight line. When setting the propulsion jack 91, the propulsion point is as close to the rotation point as possible to reduce the overturning moment.

[0024] In a preferred embodiment of the present application, Figure 4 As shown, the slide 6 includes a main beam 61, a limit plate 62 and a slide plate 63; an inverted L-shaped limit plate 62 is fixed on both sides along the length direction of the main beam 61, the main beam 61 and the limit plate 62 constitute the slide 6 space, and a slide plate 63 is fixed on the top of the main beam 61 to facilitate the sliding of the support structure 71; by setting the limit plate 62, the sliding bottom plate 73 of the support structure 71 is limited to slide in the slide 6 space, thereby preventing the support structure 71 from overturning and ensuring the stability of the sliding member 7.

[0025] In a preferred embodiment of the present application, there are multiple supporting brackets 8.

[0026] Example: A construction method using the construction device as claimed in claim 5, comprising the following steps: S1, such as Figure 6 As shown, the number of supporting brackets 8 is reasonably arranged according to the length of the turning member. When the number of supporting brackets 8 is multiple, the supporting brackets 8 are arranged at intervals, and then the fixed supporting brackets 8 are installed, the sliding member 7 is adjusted to the initial position of the sliding groove 6, and the rotating reaction member 5 is installed on the member to be turned 3; S2, such as Figure 1 As shown, after the lifting equipment 1 is in place, the component to be turned over 3 is transported to the turning operation area, and the lifting equipment 1 lifts the upper hanging point 2 of the component to be turned over 3. The component to be turned over 3 is in an upright state at this time, and the rotating reaction member 5 of the rotating surface is pressed against the rotating steel pipe 72 of the sliding bracket to prepare for the turning operation; S3, such as Figure 7As shown, the propulsion cylinder of the sliding bracket is slowly pushed forward, and the hanging point 2 remains vertical and motionless until the distance between the center of gravity of the component and the rotating hinge point is Δ≥30cm, where Δ is the horizontal distance between the center of gravity of the component and the rotating hinge point. In this embodiment, the axis of the steel pipe can be used as the rotating hinge point, the sliding member 7 is locked, and the propulsion cylinder stops supplying oil to maintain the extended length; S4, such as Figure 8 As shown, the boom of the lifting device 1 rotates slowly, controlling the upper hanging point 2 to rotate slowly around the rotating hinge; S5, such as Fig. 9 As shown, continue to execute step S4 until the component is turned over; S6. Lift the component that has been turned from vertical to horizontal, tighten the propulsion cylinder to its initial state, and prepare for the next component turning operation.

[0027] The construction method in this embodiment is aimed at the construction of flipping the component from a vertical to a horizontal position, and is particularly suitable for the situation where the bottom opening needs to be protected by a sensitive structure 4. The characteristic of this method is that a rotating reaction member 5 is pre-embedded under the component, and the vertical component is tilted by pushing the sliding member 7, and then slowly turned over under the action of gravity. The characteristic of this invention is that it avoids the inevitable crooked and slanted state of the lifting equipment 1 in the traditional turning construction, and effectively protects the sensitive structure 4 under the component. This method has controllable construction, high safety factor, simple structure and low construction cost.

[0028] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the embodiments shown and described herein.
