Description

Technical Field

[0001] This utility model relates to the field of lifting equipment safety technology, and in particular to a vacuum suction cup device that can be hydraulically flipped. Background Technology

[0002] In highway construction, various types of concrete barriers are often needed to divide lanes. These concrete barriers need to be cast in one piece using molds. They are heavy during demolding, and traditional methods rely on pre-embedded lifting holes, using forklifts or cranes with ropes for demolding. During demolding, due to the hard contact and the potential for significant swaying caused by the change in the barrier's center of gravity after lifting, the barriers can experience surface wear and internal cracks. Furthermore, the concrete barriers need to be flipped to a vertical position, generally requiring the coordinated operation of flipping and lifting equipment; a single piece of equipment can hardly complete the flipping process alone.

[0003] In summary, the shortcomings of the existing technology are as follows:

[0004] 1. High damage rate: The hard contact between the rope and the isolation strip leads to surface wear and structural damage.

[0005] 2. Low efficiency: The design of the lifting hole increases the complexity of the mold, and it needs to be turned over manually or by special equipment after demolding.

[0006] 3. High cost: Specialized flipping equipment is expensive, and manual operation is labor-intensive.

[0007] 4. Frequent handling and low precision: Sometimes, due to the disordered placement of the mold, it is necessary to flip the cement isolation strip from a horizontal to a vertical position. After that, the cement isolation block still needs to be rotated horizontally by 180 degrees to achieve the required posture. Rotating horizontally by 180 degrees usually requires the lifting equipment to change the working position or to change other equipment to complete the task. The working radius is large. In this situation, the cement isolation block needs to be handled multiple times. The precision will decrease during the handling process, and wear will also increase. Utility Model Content

[0008] In order to overcome the shortcomings of the prior art, this application proposes a hydraulically flip-over vacuum suction cup device to solve the problems existing in the prior art.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0010] A hydraulically tiltable vacuum suction cup device includes a frame, a vacuum suction cup, a hydraulic cylinder, and a linkage mechanism. The frame has a lifting docking interface at the top and is hinged to the linkage mechanism at the bottom. The vacuum suction cup is connected to the end of the linkage mechanism. One end of the hydraulic cylinder is hinged to the frame, and the other end is hinged to the linkage mechanism. The piston rod extends and retracts, driving the linkage mechanism to swing, thus switching the vacuum suction cup between a horizontal state and a left / right vertical state.

[0011] As a further technical solution of this utility model: the linkage mechanism includes:

[0012] L-shaped connecting rod: One end is hinged to the equipment frame via connecting shaft one, and the other end is hinged to the cylinder piston rod via connecting shaft two;

[0013] One-line connecting rod A: One end is hinged to the connecting shaft via a three-L-shaped connecting rod, and the other end is hinged to the middle of the suction cup rod;

[0014] Connecting shaft four: Located at the bottom of the equipment frame, it is used to hinge the lower end of the suction cup rod, allowing the suction cup rod to rotate around connecting shaft four;

[0015] I-shaped connecting rod B: Connected to the suction cup rod.

[0016] As a further technical solution of this utility model: the vacuum suction cup is an array structure, which includes multiple independent suction cup units. Each unit is controlled by an electromagnetic valve to adapt to cement isolation blocks of different sizes.

[0017] As a further technical solution of this utility model: the docking interface between the equipment frame and the lifting device is a quick-release flange structure.

[0018] As a further technical solution of this utility model: An angle sensor is provided on both the first connecting shaft and the second connecting shaft to monitor the flip angle of the vacuum suction cup in real time and feed it back to the hydraulic system controller.

Detailed Implementation

[0035] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] like Figure 1-8As shown, 1. A hydraulically tiltable vacuum suction cup device, comprising a device frame 1, a vacuum suction cup 4, a hydraulic cylinder 2, and a linkage mechanism 3; characterized in that the top of the device frame 1 is provided with a lifting docking interface, and the bottom is hinged to the linkage mechanism 3; the vacuum suction cup 4 is connected to the end of the linkage mechanism 3; one end of the hydraulic cylinder 2 is hinged to the device frame 1, and the other end is hinged to the linkage mechanism 3, and the linkage mechanism 3 is driven to swing by the extension and retraction of the piston rod, thereby driving the vacuum suction cup 4 to switch between a horizontal state and a left / right vertical state.

[0037] The linkage mechanism 3 includes: an L-shaped linkage 33, one end of which is hinged to the equipment frame 1 via a connecting shaft 1 32, and the other end of which is hinged to the piston rod of the hydraulic cylinder 2 via a connecting shaft 2 34; a straight linkage A 36, one end of which is hinged to the L-shaped linkage 33 via a connecting shaft 35, and the other end of which is hinged to the middle of the suction rod 38; a connecting shaft 4 37, located at the bottom of the equipment frame 1, used to hinge the lower end of the suction rod 38, so that the suction rod 38 can rotate around the connecting shaft 4 37; and a straight linkage B 39, connected to the suction rod 38.

[0038] The vacuum suction cup 4 has an array structure, containing multiple independent suction cup units. Each unit is controlled by a solenoid valve to adapt to cement isolation blocks 5 of different sizes. The docking interface between the equipment frame 1 and the lifting device is a quick-release flange structure. Angle sensors are installed on both connecting shaft 1 32 and connecting shaft 2 34 to monitor the flip angle of the vacuum suction cup 4 in real time and provide feedback to the hydraulic system controller.

[0039] During operation, the equipment frame needs to be connected to the customer's lifting device. The docking section at the top of the equipment frame can be customized according to the customer's lifting device. The device is then hoisted above the mold using the lifting device. Next, the vacuum suction cups (4) are slowly approached and adsorbed onto the cement block. The lifting device then rises, causing the vacuum suction cups to demold the cement block. After demolding, the hydraulic cylinder (2) activates, driving the linkage mechanism (3) to rotate the vacuum suction cups (4) and the cement block (5) from a horizontal to a vertical position. Figure 3 As shown, the cement block is then slowly lowered to the ground, the adsorption stops, and the cement block is separated, thus beginning the demolding and flipping of the next cement block.

[0040] The working principle is as follows:

[0041] First, connect the customer's lifting device to the equipment frame. Then, move the invention above the cement block that needs to be demolded. Use the vacuum suction cup to pick up the cement block, allowing it to detach from the mold. Subsequently, the equipment's hydraulic cylinder activates, driving the linkage mechanism to move, thus causing the vacuum suction cup to flip to a vertical position. In actual operation, the mold placement may not be consistent, resulting in some cement blocks needing to be flipped to the left to achieve a vertical position, and others to the right. Figure 7 , Figure 8 As shown, in the design of the equipment, when the hydraulic cylinder is at the half-stroke position, the suction cup is in a horizontal state. When the hydraulic cylinder extends from the half-stroke position to the full stroke position, the suction cup flips from the horizontal state to the left to the vertical state. When the hydraulic cylinder retracts from the half-stroke position to the zero-stroke position, the suction cup flips from the horizontal state to the right to the vertical state. The principle of this process is explained through a simplified diagram of the linkage mechanism, as shown in the diagram below. Figure 4 As shown, the position in the figure is based on Figure 2 The position of the linkage mechanism is simplified. ① is a simplified diagram of the hydraulic cylinder. 32, 34, 35, and 37 are simplified diagrams of the connecting shafts, which are circles. The positions of 32 and 37 are fixed, allowing only rotational movement. 33, 36, and 39 are connecting rods, with 33 being an "L"-shaped connecting rod, and 36 and 39 being "I"-shaped connecting rods. 38 is a simplified diagram of the suction cup's connecting rod. When the hydraulic cylinder retracts from the half-stroke position to the zero-stroke position, the L-shaped connecting rod 33, under the action of the hydraulic cylinder, rotates to the upper right around the connecting shaft 32. The L-shaped connecting rod 33 drives the "I"-shaped connecting rod A36 to move to the upper right. The "I"-shaped connecting rod A36 then drives the suction cup rod 38 to rotate to the upper right around the connecting shaft 37. When the hydraulic cylinder reaches the zero-stroke position, the position of the linkage mechanism is as follows: Figure 5 As shown, that is, the equipment is as follows Figure 7 The position shown; when the hydraulic cylinder extends from the half-stroke position to the full stroke position, the L-shaped connecting rod 33, under the action of the hydraulic cylinder, rotates to the lower left around the connecting shaft ②. The L-shaped connecting rod 33 drives the straight connecting rod A36 to move to the upper left. The straight connecting rod A36 drives the suction cup rod 38 to rotate to the upper left around the connecting shaft 37. When the hydraulic cylinder reaches the full stroke position, the position of the linkage mechanism is as follows. Figure 6 As shown, that is, the equipment is as follows Figure 8 The location shown is thus determined to meet the customer's needs.
