Description

Technical Field

[0001] The present invention relates to the technical field of wind power tower tube piece production equipment, in particular to a multi-stage adjustable wind power hybrid tower mould. Background Art

[0002] Wind turbine hybrid tower molds are key equipment in wind turbine hybrid tower production, primarily used to form precast concrete tower segments. Vertical modular molds are widely used due to their high precision and ease of mass production. Furthermore, these molds can be adjusted to produce tower segments of varying thicknesses, resulting in high mold utilization.

[0003] However, when using existing vertical wind turbine hybrid tower molds to produce tower segments, the following problems arise: due to the inevitable need for transportation of molds produced in batches and the consideration of the production site area, the opening and closing stroke of the outer mold of the vertical mold is limited. During the casting stage of the tower segment production, the segment steel skeleton needs to be hoisted into the mold. The smaller mold spacing requires more precise operating specifications and longer working time to prevent the steel skeleton from scratching and colliding with the mold due to excessive shaking, thereby causing damage to the mold and the steel skeleton. During the demolding stage, the thickness of the tower segment after casting is greater than the steel skeleton. At the same time, the surface concrete is more susceptible to scratches and bumps and damage, which increases the workload of repair and also poses a certain threat to the structural strength of the tower segment.

[0013] Furthermore: a plurality of limiting sleeve rods are provided at equal intervals on the bottom of the sliding base plate, and the limiting sleeve rods and the fixed base plate form a matching mechanism.

[0014] Furthermore: it also includes multiple sliding pushing components that cooperate with the bottom frame of the mold platform.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The outer mold, sliding base plate and sliding push assembly provided in the present invention, when hoisting and demoulding, as the height of the tower segment increases, the pressure above the sliding base plate disappears, so that the outer mold body is hoisted and deflected outward to open, so that the hoisted tower segment has a larger moving space during hoisting, reducing the scratch damage of the tower segment during hoisting. At the same time, when the tower segment skeleton is hoisted next time, when the tower is placed on the sliding base plate, the sliding base plate is pressed down under the action of its gravity, and the outer mold body is hoisted and reset by the sliding push assembly. In this way, the hoisting is convenient for the auxiliary workers to effectively adjust the opening and closing of the mold, so that there is a large fault tolerance space for the installation of the tower segment skeleton and the demoulding and hoisting of the tower segment.

[0022] 2. The sliding track provided in the present invention, when the tower is solidified and demoulded, when the outer mold body is pulled by the pulling equipment, synchronously drives the sliding track to move, thereby pushing the track wheel and causing the sliding base plate to move slightly upward. At this time, the sliding base plate is higher than the adjusting plate. Under the action of pushing, multiple surfaces of the tower piece are separated from the inner wall of the mold, thereby further opening the outer mold body. In this way, when the tower piece is lifted after subsequent maintenance, the start of lifting can be made more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] The present invention will be further described below with reference to the accompanying drawings: Figures 1-8As shown, the multi-stage adjustable wind power hybrid tower mold includes a mold base bottom frame 1, a bottom mold 2 arranged on the mold base bottom frame 1, an inner mold 3 and an outer mold 4 are respectively provided on both sides of the bottom mold 2, and the outer mold 4 is slidably matched with the mold base bottom frame 1; a side mold 5, which serves as a side plate of the casting mold groove, is arranged on both sides of the inner mold 3 and the outer mold 4, and forms a matching mechanism with the inner mold 3 and the outer mold 4; a distance adjustment locking assembly 6, which is arranged on the peripheral side end wall of the inner mold 3 and the outer mold 4, and is used for mold closing adjustment and fixation.

[0037] During operation, the bottom mold 2 is bolted to the upper end surface of the mold base bottom frame 1, and the inner mold 3 is bolted to the inner side of the bottom mold 2. The positions of the bottom mold 2 and inner mold 3 are adjustable. The positions of the bottom mold 2 and inner mold 3 are adjusted according to production needs and fixed to the mold base bottom frame 1 with bolts. When casting the tower shell, the outer mold 4 and inner mold 3 are closed and the distance adjustment and locking assembly 6 are used to limit and fix the entire mold.

[0038] As an embodiment of the present invention, Figure 2 、 Figure 5 and Figure 6 As shown, the outer mold 4 includes an outer mold body 41, and a plurality of limiting pulley groups 44 for supporting the outer mold body 41 are fixed at the bottom of the outer mold body 41, and a limiting slide 43 is provided below the limiting pulley group 44, and the limiting slide 43 is fixed on the bottom frame 1 of the mold platform; the limiting pulley group 44 includes an outer mold support seat 441 fixed on the lower end surface of the outer mold body 41, and a roller 443 is provided in the outer mold support seat 441, and limiting rollers 442 are provided on both sides of the roller 443; one end of the limiting slide 43 is provided with a slope for changing the sliding direction of the outer mold body 41, and the upper end surface of the limiting slide 43 is provided with a limiting retaining edge 431 for clamping the limiting roller 442 and the outer mold body 41.

[0039] During specific operation, the limiting pulley assembly 44 is fixed by bolts to the end of the lower end face of the outer mold body 41 away from the inner mold 3. The outer mold support seat 441 is fixed to the outer mold body 41, and the limiting rollers 442 installed on both sides of its bottom slide in cooperation with the inner wall of the limiting slide 43. The limiting rollers 442 and the limiting slide 43 are in line contact, and the height of their contact points is lower than the height of the lowest point of the outer mold support seat 441, so that the outer mold support seat 441 will not interfere with the limiting slide 43 during movement. A curved slope is set at the end of the limiting slide 43, and the limiting retaining edge 431 is welded to the upper end face of the limiting slide 43 and the inner wall of the limiting slide 43 to form a slide that limits the limiting roller 442. When the mold is opened, when the outer mold body 41 moves to the end, the limiting roller 442 moves along the curved slope, thereby causing the outer mold body 41 to deflect around the axis of the roller 443.

[0040] As an embodiment of the present invention, Figure 1-6As shown, the bottom mold 2 includes a fixed bottom plate 21 fixed to the mold base bottom frame 1. The upper end surface of the fixed bottom plate 21 is provided with a plate groove, in which the sliding bottom plate 22 slidably fits. The lower end surface of the sliding bottom plate 22 is fixed with multiple bottom mold supports 24, and the bottom mold supports 24 extend through the fixed bottom plate 21. The bottom of the sliding bottom plate 22 is provided with multiple limit rods 23 at equal intervals, and the limit rods 23 and the fixed bottom plate 21 form a mating mechanism.

[0041] During operation, the sliding base plate 22 cooperates with the inner wall of the inner mold 3 and is used as a bottom mold when casting the tower tube. The limiting sleeve 23 provided at the bottom of the sliding base plate 22 limits the sliding base plate 22 so that it can only slide up and down along the limiting sleeve 23.

[0042] As an embodiment of the present invention, Figure 1-6 As shown, it also includes multiple sliding push assemblies 8 that cooperate with the bottom frame 1 of the mold base. One end of the sliding push assemblies 8 cooperates with the bottom mold support 24, and the other end of the sliding push assemblies 8 is hinged to the outer mold body 41. The bottom mold support 24 includes a roller support 241 fixed to the lower end surface of the sliding base plate 22, and a track wheel 242 is embedded in the roller support 241. The sliding push assemblies 8 include a limiting slide 81 fixed between the bottom of the mold base frame 1 and the bottom mold 2, and a sliding track 82 is slidably engaged in the limiting slide 81. The upper end surface of the sliding track 82 cooperates with the track wheel 242, and a convex edge for lifting the track wheel 242 is provided at the end of the sliding track 82 away from the outer mold 4. The other end of the sliding track 82 is fixedly mounted with a hinge rod 83, and the other end of the hinge rod 83 is hinged to the outer mold body 41.

[0043] The limiting slide groove 81 is fixed to the bottom of the mold base bottom frame 1, and the sliding track 82 is connected to the bottom of the outer mold body 41 through the hinge rod 83. When the outer mold body 41 moves, the sliding track 82 is driven to slide in the limiting slide groove 81. During the movement of the sliding track 82, the height of the track wheel 242 is changed by the change in the height of the contact surface between the sliding track 82 and the track wheel 242, thereby driving the sliding base plate 22 to slide along the limiting sleeve rod 23.

[0044] When doing specific work, such as Figure 4As shown, by adjusting the hinge rod 83, the track wheel 242 is located at the critical point between the smooth section b and the deflection section c of the sliding track 82. At this time, the outer mold body 41 is in a vertical state. When the outer mold body 41 deflects, it pulls the sliding track 82 to slide backward through the hinge rod 83. At this time, the deflection section c of the sliding track 82 pushes the track wheel 242 to drive the sliding base plate 22 to move upward. When there is no weight pressing down on the sliding base plate 22, the outer mold body 41 is in a critical state and deflects outward to open under the action of gravity, or is manually assisted to open. Similarly, when there is a heavy object pressing down on the sliding base plate 22, the track wheel 242 presses down the deflection section c to push the sliding track 82 to move forward along the limiting slide groove 81, thereby lifting and pulling the outer mold body 41 to deflect inward through the hinge rod 83 and return to the vertical state. In this way, when the tower segment is hoisted and demoulded, as the height of the tower segment increases, the pressure above the sliding base plate 22 disappears, so that the outer mold body 41 is hoisted and deflected outward to open, so that the hoisted tower segment has a larger moving space during the hoisting process, reducing the scratch damage of the tower segment during the hoisting. At the same time, when the tower segment skeleton is hoisted next time, when the tower is placed on the sliding base plate 22, the sliding base plate 22 is pressed down under the action of its gravity, and the outer mold body 41 is hoisted and reset through the sliding push assembly 8. In this way, the hoisting makes it easier for the auxiliary workers to effectively adjust the opening and closing of the mold, so that there is a larger fault tolerance space for the installation of the tower segment skeleton and the demoulding hoisting of the tower segment.

[0045] As an embodiment of the present invention, Figure 4-8 As shown, the outer mold 4 also includes an adjustment plate 42 fixed to the bottom of the outer mold body 41, and the adjustment plate 42 and the sliding base plate 22 form a mating mechanism. An inner mold support assembly 7 is provided between the inner concave surface of the inner mold 3 and the mold base frame 1. The sliding base plate 22 is a non-adjustable base mold. The adjustment plate 42 at the bottom of the outer mold body 41 cooperates with the sliding base plate 22 to form a complete tower mold base mold. When tower segments with different wall thicknesses need to be produced, this can be achieved by replacing the adjustment plate 42 with different inward extension widths.

[0046] like Figure 4 The upper end surface of the sliding track 82 is provided with an inclined groove for demoulding and pushing. The inclined groove is located in the lifting section a.

[0047] During specific operation, when the mold is fully closed, the sliding base plate 22 sinks completely, and its height is consistent with the adjustment plate 42. At this time, the track wheel 242 is in the lifting section a. By adjusting the hinge rod 83, the inclined surface of the lifting section a is made tangent to the track wheel 242. When the tower is solidified and demoulded, when the outer mold body 41 is pulled by the pulling equipment, the sliding track 82 is simultaneously driven to move, thereby pushing the track wheel 242, causing the sliding base plate 22 to move slightly upward. At this time, the sliding base plate 22 is higher than the adjustment plate 42. Under the action of the push, multiple surfaces of the tower piece are separated from the inner wall of the mold, thereby further opening the outer mold body 41. In this way, when the tower piece is lifted after subsequent maintenance, the lifting start can be made more stable, so that it can pass smoothly through the narrow area at the bottom.

[0048] Working Principle: A curved slope is provided at the end of the limiting slideway 43. A limiting rib 431 is welded to the upper end surface of the limiting slideway 43 and the inner wall of the limiting slideway 43, forming a slideway for the limiting roller 442. When the mold is opened and the outer mold body 41 moves to the end, the limiting roller 442 moves along the curved slope, causing the outer mold body 41 to deflect about the axis of the roller 443.

[0049] By adjusting the hinge rod 83, the track wheel 242 is positioned at the critical point between the smooth section b and the deflection section c of the sliding track 82. At this point, the outer mold body 41 is in a vertical position. When the outer mold body 41 deflects, it pulls the sliding track 82 backward through the hinge rod 83. At this point, the deflection section c of the sliding track 82 pushes the track wheel 242, driving the sliding base plate 22 upward. When there is no weight pressing down on the sliding base plate 22, the outer mold body 41 is in a critical position and deflects outward to open under the action of gravity, or is manually assisted to open. Similarly, when there is a weight pressing down on the sliding base plate 22, the track wheel 242 presses down the deflection section c, pushing the sliding track 82 forward along the limiting slide groove 81, thereby pulling the outer mold body 41 inward through the hinge rod 83 and returning to a vertical position.
