[0016] The present invention has the following beneficial effects:

[0017] 1. In the precast concrete product turning device, the support cross bars installed on the two support frames are beneficial to improving the strength of the device structure. Through the moving wheels arranged in the installation grooves on both sides of the support frame, it is convenient for the device to be flexibly moved above the precast concrete mold that needs to be turned during use. Through the first servo hydraulic cylinder arranged in the device, the horizontal clamping position of the mechanical claw can be adjusted, so that the set mechanical claw can conveniently clamp on the C-shaped plates arranged at both ends of the precast concrete mold. Through the lifting component arranged on the support frame, the precast concrete mold together with the internal concrete product can be quickly lifted by a certain height for turning operation;

[0018] When the precast concrete mold together with the internal concrete product is lifted by a certain height, the servo motor fixed on the mounting plate can drive the mechanical claw to rotate, so as to achieve the purpose that the opening of the precast concrete mold can quickly face downwards for reverse buckling, which can greatly improve the turning efficiency, reduce the number of manual operations, save time and effort, be convenient and fast, and improve the safety of operation.

[0019] 2. In the turning device for prefabricated cement products, the first sliding bracket fixed at both ends of the cement prefabrication mold can be slidably connected to the U-shaped plate, so as to achieve the purpose that the cement prefabrication mold has the function of vertically sliding up and down. Through the second sliding bracket arranged on the U-shaped plate, it can be slidably connected to the sliding block fixed on the contact plate. When the first strip groove opened on the contact plate is connected to the first sliding bracket, the purpose that the contact plate can horizontally move within the U-shaped plate can be achieved, so that the trapezoidal contact block fixed on the contact plate can contact the strip contact block fixed at the end of the cement prefabrication mold during horizontal movement, which is convenient for the cement prefabrication mold to vibrate up and down when moving down after turning, and can achieve the effect of improving the demolding of the cement products from the cement prefabrication mold, enabling the cement products to smoothly fall off from the cement prefabrication mold and reducing the operation of manually demolding after the cement prefabrication mold is turned.

[0020] Through a number of equally spaced arc-shaped protrusions arranged at one end of the trapezoidal contact block, when the contact plate drives the trapezoidal contact block to horizontally move and contact the strip contact block, the strip contact block can contact a number of equally spaced arc-shaped protrusions, so that the generated vibration force can act on the turned cement prefabrication mold, improving the demolding effect of the cement products. The U-shaped frame slidably connected to the support cross bar facilitates the installation of a number of equally spaced arc-shaped contact blocks. When the cement prefabrication mold turns and moves vertically, it can drive the contact plate to move downward synchronously, achieving the purpose that both ends of the contact plate can contact the arc-shaped contact blocks fixed on both sides of the U-shaped frame in sequence, prompting the contact plate to continuously move horizontally back and forth, enabling the cement prefabrication mold to continuously vibrate up and down, and further improving the demolding effect of the cement products. The electric push rod can drive the strip contact rod to contact the contact piece fixed on the U-shaped frame, facilitating the adjustment of the horizontal working position of the U-shaped frame to avoid obstructing the upward moving cement prefabrication mold. After the cement prefabrication mold is turned, the U-shaped frame can drive a number of arc-shaped contact blocks to horizontally move to one side of the contact plate, facilitating the contact between the contact plate and a number of arc-shaped contact blocks.

[0021] 3. In the turning device for prefabricated cement products, the second guide rod slidably connected to the U-shaped plate can, under the action of the fourth spring, achieve the purpose of driving the limit rod and the limit wedge block fixed on the limit rod to abut against the strip contact block, facilitating the limit wedge block to limit the limit block fixed on the strip contact block, so that when the trapezoidal contact block contacts the strip contact block, it is convenient to limit the vertical movement height of the cement prefabrication mold, facilitating energy storage. When the trapezoidal contact block and the strip contact block are disengaged, the triangular contact block fixed on one side of the trapezoidal contact block contacts the L-shaped contact strip fixed on the limit rod, prompting the limit wedge block to release the limit on the limit block, enabling the strip contact block to drive the cement prefabrication mold to swing vertically with a larger amplitude, and greatly improving the demolding effect of the cement products.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1. Please refer to Figures 1 to 9 , a turnover device for prefabricated cement products, including a cement prefabrication mold 2 and support frames 1 located at both ends of the cement prefabrication mold 2. A support crossbar 3 is fixed above the support frames 1, and a lifting assembly is arranged on the support frames 1. A first servo hydraulic cylinder 4 is fixed on the lifting assembly. An installation plate 5 is fixed at the end of the first servo hydraulic cylinder 4. A servo motor 6 is fixed on the installation plate 5, and a mechanical claw 7 is fixed on the motor shaft of the servo motor 6;

[0034] C-shaped plates 8 are respectively arranged at both ends of the cement prefabrication mold 2, and first sliding brackets 9 are respectively fixed at both ends of the cement prefabrication mold 2. The C-shaped plates 8 are slidably connected to the first sliding brackets 9, and a first spring 10 is connected between the C-shaped plates 8 and the first sliding brackets 9.

[0035] The lifting assembly includes sliding rods 101, which are fixed on both sides of the support frames 1, and a sliding seat 102 is slidably connected to the sliding rods 101. A second servo hydraulic cylinder 103 is fixed at the top of the support frames 1, and the lower end of the second servo hydraulic cylinder 103 is fixedly connected to the sliding seat 102.

[0036] A first guide rod 11 is fixed on the installation plate 5, and the first guide rod 11 is slidably connected to the sliding seat 102. Installation grooves 12 are formed on both sides of the support frames 1, and moving wheels 13 are arranged in the installation grooves 12. Both ends of the moving wheels 13 are rotatably connected to the support frames 1.

[0037] When the device works, refer to Figure 1-Figure 2, through the moving wheels 13 arranged in the installation grooves 12 on both sides of the support frame 1, it is convenient to flexibly move the support frame 1 directly above the precast cement mold 2 to be flipped. At this time, the mechanical claws 7 are located at both ends of the precast cement mold 2. The first servo hydraulic cylinder 4 installed on the lifting assembly drives the mounting plate 5 to move horizontally, enabling the servo motor 6 and the mechanical claws 7 to move synchronously, prompting the mechanical claws 7 to press against the middle position of the U-shaped plate 8 arranged at the end of the precast cement mold 2 for clamping. At the same time, the first guide rod 11 slides horizontally on the sliding seat 102 in the lifting assembly, which can improve the stability of the horizontal movement of the mounting plate 5. The second servo hydraulic cylinder 103 in the lifting assembly can drive the sliding seat 102 to move vertically and steadily upward on the two sliding rods 101, thereby achieving the purpose of lifting the precast cement mold 2 together with the cement products inside to a certain height. The servo motor 6 fixed on the mounting plate 5 can drive the mechanical claws 7 to rotate, thereby achieving the purpose of quickly turning the opening of the precast cement mold 2 downward for inversion, which can greatly improve the inversion efficiency, reduce the number of manual operations, save time and effort, be convenient and fast, and improve the safety of operation.

[0038] Embodiment 2 is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 9 , a抵触板14 is arranged on the U-shaped plate 8, a first strip-shaped groove 15 is opened on the抵触板14, the first sliding bracket 9 is inserted into the first strip-shaped groove 15, a second strip-shaped groove 16 is opened on the U-shaped plate 8, a sliding block 17 is slidably connected to the second strip-shaped groove 16, the sliding block 17 is fixedly connected to the抵触板14, and a second sliding bracket 18 is fixed on the U-shaped plate 8. The second sliding bracket 18 is elastically connected to the sliding block 17 through a second spring 19.

[0039] Strip-shaped抵触块20 are fixed at both ends of the precast cement mold 2, a trapezoidal抵触块22 is fixed on the抵触板14, and the trapezoidal抵触块22 abuts against the strip-shaped抵触块20.

[0040] A抵触斜面21 is opened at one end of the strip-shaped抵触块20, and a plurality of arc-shaped凸块23 are arranged at one end of the trapezoidal抵触块22 at equal intervals.

[0041] A U-shaped frame 24 is arranged above the抵触板14. A plurality of arc-shaped抵触块25 are respectively arranged at both ends of the U-shaped frame 24. A third strip-shaped groove 26 is opened on the support cross bar 3. The U-shaped frame 24 is slidably connected in the third strip-shaped groove 26, and a third spring 27 is connected between the U-shaped frame 24 and the support cross bar 3.

[0042] A抵触片28 is fixed on the U-shaped frame 24. An electric push rod 29 is fixed on one of the support cross bars 3. A strip-shaped抵触杆30 is fixed on the electric push rod 29, and the抵触片28 abuts against the strip-shaped抵触杆30.

[0043] To facilitate the demolding of the cement product during the flipping process of the cement precast mold 2, refer to Figure 1-Figure 6 , in the initial state, the U-shaped frame 24 is located on one side of the抵触 plate 14, which can prevent the抵触 plate 14 that flips synchronously from being obstructed during the flipping process of the cement precast mold 2. When the抵触 plate 14 finishes flipping, the electric push rod 29 drives the strip抵触 rod 30 to move horizontally, prompting the strip抵触 rod 30 to抵触 the抵触 pieces 28 fixed on the two U-shaped frames 24, so as to achieve the purpose of the U-shaped frame 24 sliding horizontally in the first strip groove 15 opened on the support cross bar 3 under the influence of the抵触 force, prompting the U-shaped frame 24 to drive a number of equally spaced arc抵触 blocks 25 to move under the抵触 plate 14, and the third spring 27 stores energy, so that both ends of the抵触 plate 14 can reciprocally抵触 the number of arc抵触 blocks 25 at both ends of the U-shaped frame 24 in sequence during the downward movement of the抵触 plate 14. At the same time, the sliding block 17 fixed on the抵触 plate 14 slides on the second strip groove 16 opened on the U-shaped plate 8, and one end of the sliding block 17 also slides on the second sliding bracket 18 fixed on the U-shaped plate 8, and the second spring 19 stores energy, so that the抵触 plate 14 can drive the trapezoidal抵触 block 22 to抵触 the strip抵触 block 20 fixed on the end of the cement precast mold 2 under the influence of the抵触 force of the arc抵触 block 25, prompting the strip抵触 block 20 to drive the cement precast mold 2 to move vertically upward to lift the height. At the same time, the first sliding bracket 9 slides on the U-shaped plate 8, and the first spring 10 stores energy. When the trapezoidal抵触 block 22 continues to move horizontally, the抵触 on the strip抵触 block 20 can be released, which is convenient for the cement precast mold 2 to vibrate up and down when moving downward after flipping, so as to achieve the effect of improving the demolding of the cement product from the cement precast mold 2, so that the cement product can fall off smoothly from the cement precast mold 2 under the influence of the swinging force, and reduce the operation of manually demolding the cement precast mold 2 after flipping;

[0044] To improve the effect of the cement product falling off from the cement precast mold 2, refer to Figure 4-Figure 7 , through a number of equally spaced arc凸块 23 provided at one end of the trapezoidal抵触 block 22, when the抵触 plate 14 drives the trapezoidal抵触 block 22 to move horizontally and抵触 the strip抵触 block 20, the strip抵触 block 20 can continuously抵触 the number of equally spaced arc凸块 23, so that the generated vibration force can act on the flipped cement precast mold 2, improving the demolding effect of the cement product;

[0045] A number of arc抵触 blocks 25 fixed on both sides of the U-shaped frame 24 are arranged in a staggered manner, so that when the抵触 plate 14 moves downward along with the cement precast mold 2, both ends of the抵触 plate 14 can be抵触 by the arc抵触 blocks 25, prompting the抵触 plate 14 to move horizontally back and forth continuously, so that the cement precast mold 2 can continuously vibrate up and down, further improving the demolding effect of the cement product.

[0046] When the first strip groove 15 formed in the abutting plate 14 is connected to the first sliding bracket 9, the purpose that the abutting plate 14 can horizontally move within the U-shaped plate 8 is realized, so that the trapezoidal abutting block 22 fixed on the abutting plate 14 can abut against the strip-shaped abutting block 20 fixed at the end of the cement precast mold 2 during horizontal movement, and the first sliding bracket 9 that remains stationary obstructs the horizontally moving abutting plate 14.

[0047] Embodiment 3 is an improvement made on the basis of Embodiment 2. Specifically, please refer to Figures 1 to 9 , a second guide rod 31 is slidably connected to the U-shaped plate 8. One end of the second guide rod 31 is fixed with a limiting rod 32. The limiting rod 32 is elastically connected to the U-shaped plate 8 through a fourth spring 33. One side of the strip-shaped abutting block 20 is fixed with a limiting block 34. A limiting wedge block 35 is fixed on the limiting rod 32. The limiting block 34 is in contact with the limiting wedge block 35.

[0048] One side of the trapezoidal abutting block 22 is fixed with a triangular abutting block 36. An L-shaped abutting strip 37 is arranged inside the U-shaped frame 24. One end of the L-shaped abutting strip 37 is fixed on the limiting rod 32.

[0049] In order to further improve the demolding efficiency of the cement product from the cement precast mold 2, refer to Figure 8 、 Fig. 9 , the limiting block 34 fixed on the strip-shaped abutting block 20 is located on one side of the limiting rod 32. When the strip-shaped abutting block 20 is abutted, it can drive the limiting block 34 to move upward. By moving the limiting block 34 against the limiting wedge block 35, since the limiting wedge block 35 is abutted, it can push the limiting rod 32 to move horizontally, so that the limiting block 34 can move above the limiting wedge block 35, and the purpose of limiting the strip-shaped abutting block 20 by the limiting block 34 can be realized. At this time, the vertical movement height of the strip-shaped abutting block 20 reaches the maximum. When the trapezoidal abutting block 22 horizontally moves to release the abutment against the strip-shaped abutting block 20, at the same time, the triangular abutting block 36 fixed on one side of the trapezoidal abutting block 22 abuts against the L-shaped abutting strip 37 fixed on the limiting rod 32, which causes the limiting rod 32 to drive the second guide rod 31 to slide on the U-shaped plate 8, and the fourth spring 33 stores energy. The purpose of driving the limiting wedge block 35 to move to one side by the limiting rod 32 to release the limit on the limiting block 34 can be realized, so that the amplitude of the up and down vibration of the strip-shaped abutting block 20 in the U-shaped plate 8 is larger, thereby improving the demolding efficiency of the cement product from the cement precast mold 2.
