Description

Technical Field

[0001] This utility model belongs to the field of precast component production equipment, and specifically relates to a precast component flipping device. Background Technology

[0002] Precast concrete components are used in the construction industry for precast steel structure foundations, precast floor slabs, precast stairs, etc. Precast component production lines are typically equipped with a tilting device for turning over precast components on the trolley, facilitating the removal and lifting of the components by a crane.

[0003] For example, invention patent CN109502523A discloses a flipping table that addresses the problem of inconvenience in using existing flipping devices when flipping large prefabricated components in confined spaces. It provides a flipping table that effectively saves space required for flipping large prefabricated components. According to its description, the base is slidable, and a transmission mechanism is set on one side of the base to drive the base to move left and right, achieving the flipping of the structure during the movement. However, due to the transmission mechanism and the movement of the base, this technical solution still requires a relatively large space in the horizontal plane. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a prefabricated component flipping device that can be applied to confined spaces.

[0005] The technical solution adopted in this utility model is: A precast component flipping device includes a base, slide rails disposed on the left and right sides of the base surface, sliders disposed on the slide rails, and flipping tables disposed on the two sliders via a rotating shaft. The flipping tables include a first flipping platform and a second flipping platform disposed vertically. The rotating shaft is disposed at the vertical intersection of the first flipping platform and the second flipping platform. A first hydraulic cylinder is disposed between the base and the first flipping platform, and a second hydraulic cylinder is disposed between the base and the second flipping platform.

[0006] Furthermore, one end of the first hydraulic cylinder is rotatably connected to the left end of the base, and the other end is rotatably connected to the free end of the first tilting platform; one end of the second hydraulic cylinder is rotatably connected to the right end of the base, and the other end is rotatably connected to the free end of the second tilting platform.

[0007] Furthermore, a limiting block is provided at each of the left and right ends of the slide rail to limit the first and second extreme positions of the slider, respectively.

[0008] Furthermore, a shock-absorbing pad is provided on the contact surface between the limiting block and the slider.

[0009] Furthermore, there are stops at both ends of the base and between the two slide rails. When the first and second flip platforms move to the horizontal position, their outer ends cooperate with the corresponding stops. A telescopic rod for driving the left and right movement is connected to the outside of the stops.

[0010] Furthermore, a notch is provided at the top of the inner side of the stop block, which mates with the end of the corresponding first or second flipping platform.

[0011] Furthermore, the bottom surface of the notch is provided with a slope.

[0012] Furthermore, the stop block is slidably mounted on the base, and the telescopic rod is an electrically operated telescopic rod.

[0013] The positive effects of this utility model are: This invention sets the fulcrum of the tilting table on the slider, which can move along the slide rail, so that the fulcrum of the tilting table can move left and right. At the same time, the tilting table is tilted by the joint action of two hydraulic cylinders, so that the movement of the fulcrum is basically kept within the length range of the first tilting platform. This can greatly reduce the space required for the tilting table during the tilting process, and is more suitable for tilting in narrow spaces. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram showing the position of the first hydraulic cylinder of this utility model; Figure 3 This is a schematic diagram of the stop block of this utility model; Figure 4 This is a schematic diagram of the component of this utility model after it has been flipped over. Detailed Implementation

[0015] As attached Figure 1-4 As shown, this embodiment discloses a precast component flipping device, including a fixed base 1, slide rails 2 disposed on the left and right sides of the top surface of the base 1, sliders 3 respectively disposed on the two slide rails 2, and a flipping platform disposed between the two sliders 3 via a rotating shaft. The flipping platform includes a vertically disposed first flipping platform 4 and a second flipping platform 5, as shown in the attached figure in the normal state. Figure 1As shown, the first tilting platform 4 is in a horizontal state, and the second tilting platform 5 is in a vertical state. The rotating shaft is located at the intersection of the first tilting platform 4 and the second tilting platform 5. A first hydraulic cylinder 7 is provided between the base 1 and the first tilting platform 4, and a second hydraulic cylinder 8 is provided between the base 1 and the second tilting platform 5. The cylinder body of the first hydraulic cylinder 7 is rotatably connected to the left end of the base 1, and the piston rod is connected to the end of the first tilting platform 4 near its free end. The cylinder body of the second hydraulic cylinder 8 is rotatably connected to the right end of the base 1, and the piston rod is connected to the end of the second tilting platform 5 near its free end.

[0016] During the flipping process, one hydraulic cylinder applies a pulling force and another hydraulic cylinder applies a pushing force, creating a rotational force that causes the flipping table to flip. During the flipping process, slider 3 slides along slide rail 2, moving from one end of the slide rail to the other, thus achieving in-situ flipping of the flipping table and saving space.

[0017] Preferably, a limiting block 14 is provided at each of the left and right ends of the slide rail 2 to limit the first and second extreme positions of the slider 3. Figure 1 In the initial state, slider 3 is at its first extreme position. Figure 4 In the reversed state, slider 3 is now in the second extreme position. To prevent excessive collisions when slider 3 contacts limit block 14 during operation, shock-absorbing pads are provided on the contact surface between limit block 14 and slider 3. These shock-absorbing pads can be installed on the left and right sides of slider 3 or on the side of limit block 14.

[0018] Stop blocks 11 are provided at both ends of the base 1, located between the two slide rails 2. When the first tilting platform 4 and the second tilting platform 5 rotate to the horizontal position, their outer ends can cooperate with the corresponding stop blocks 11. The stop blocks 11 play a certain supporting role to reduce the force requirements of the first and second hydraulic cylinders. Specifically, the stop blocks 11 are slidably set on the base 1, and a notch is provided on the top of the inner side of the top block 11. This notch cooperates with the ends of the corresponding first and second tilting platforms, which can not only play a supporting role, but also have a certain limiting role. When the first and second hydraulic cylinders do not apply force, the stop blocks 11 and the slider 3 jointly bear the weight of the tilting platform, and the stop blocks 11 and the limiting blocks 14 can be used to limit the position of the tilting platform.

[0019] To prevent the stop 11 from affecting the normal rotation of the tilting platform, a telescopic rod 12 is connected to the outside of the stop 11 to drive its left and right movement. This telescopic rod is electrically operated. During the tilting process, the stop 11 moves synchronously, and a ramp is provided on the outer side of the bottom surface of the notch to facilitate its coordination with the corresponding tilting platform.

[0020] This invention creatively adopts a movable fulcrum structure, using two hydraulic cylinders to generate a flipping force. During the flipping process, the fulcrum moves along the slide rail, achieving in-situ flipping, which can minimize the space required for flipping and reduce the floor space occupied.

[0021] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
