[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] This embodiment provides a demoulding and unloading device for precast concrete parts, and its structural schematic diagram is as follows: Figure 1-Figure 5As shown, it comprises an operating table 1; a top plate 2 arranged above the operating table 1, a hydraulic arm 3 is vertically installed at the bottom of the top plate 2, and a clamping mechanism 4 for clamping a mold is installed at the telescopic end of the hydraulic arm 3; a turning table 5 is arranged on one side of the operating table 1, and a turning plate 6 is arranged on the turning table 5, and the turning plate 6 is hinged to the arc turning table 5 at one end of the operating table 1, and a driving mechanism 7 for driving the turning plate 6 to turn toward the operating table 1 is arranged at the bottom of the turning table 5; through this structural mode, the mold with the formed precast concrete part is placed horizontally on the turning plate 6, and the driving mechanism 7 forces the turning plate 6 to turn toward the operating table 1. The flip plate 6 flips over to flip the concrete mold onto the operating table 1, and the hydraulic arm 3 is started to push the clamping mechanism 4 downward to clamp the mold. After the hydraulic arm 3 is started and retracted, the mold is clamped, and the precast concrete part is retained on the operating table 1 under the action of its own gravity, thereby realizing automatic demoulding and unloading of the precast concrete part. Compared with the manual demoulding method, the demoulding efficiency is improved and labor is saved. Compared with the demoulding method of clamping the mold to demould, the demoulding method of clamping the concrete part is easier to demould, avoiding the problem of concrete clamping and falling damage.

[0025] As a preferred technical solution in this embodiment, the driving mechanism 7 includes a slide rail 17 arranged at the bottom of the flip table 5, a second one-way screw 19 rotatably installed on the slide rail 17, a slide seat 18 slidably arranged on the slide rail 17, a lifting arm 21 hinged between the slide seat 18 and the bottom of the flip plate 6, and a second motor 20 installed at the end of the slide rail 17 for driving the second one-way screw 19 to rotate. A through groove 16 for the lifting arm 21 to pass through is opened on the flip table 5, wherein the slide rail 17 and the second one-way screw 19 are arranged vertically in the direction of the operating table 1, and the second one-way screw 19 is driven to rotate by starting the second motor 20, driving the slide seat 18 to move toward the operating table 1, forcing the lifting arm 21 to push the flip plate 6 to flip, and driving the concrete mold to flip onto the operating table 1, so as to facilitate the clamping of the mold to realize the demolding of the concrete precast part.

[0026] In this embodiment, the lifting arm 21 includes an inner arm 22 and a sleeve arm 23. The ends of the inner arm 22 and the sleeve arm 23 that are away from each other are respectively hinged to the slide 18 and the flip plate 6. The sleeve arm 23 is provided with a sliding cavity 24 at one end facing the inner arm 22. The inner arm 22 is inserted into the sliding cavity 24 and is provided with a stopper 25. The stopper 25 slides and fits with the inner wall of the sliding cavity 24. When the slide 18 moves toward the operating table 1, the inner arm 22 pushes against one end of the sliding cavity 24, and can be used to push the flip plate 6 to flip toward the operating table 1. When the angle between the flip plate 6 and the operating table 1 is less than 90°, the flip plate 6 falls, and the stopper 25 slides to the end of the sliding cavity 24, thereby extending the length of the lifting arm 21 to facilitate the flipping of the flip plate 6.

[0027] In this embodiment, a support plate 8 is vertically fixed to one end of the top of the flip plate 6 facing the operating table 1, and a groove 9 is provided on the operating table 1 and the flip plate 6 to allow the support plate 8 to rotate through. Through this structural method, when the flip plate 6 lifts the mold to flip, the support plate 8 can support the side of the mold to prevent the mold from falling directly onto the operating table 1 when it is flipped to an angle less than 90° with the operating table 1, causing damage to the precast concrete parts.

[0028] As a preferred technical solution in this embodiment, the clamping mechanism 4 includes a connecting plate 26 horizontally fixed at the telescopic end of the hydraulic arm 3, a slide groove 27 provided on the lower surface of the connecting plate 26, a bidirectional screw rod 31 rotatably installed in the slide groove 27, a pair of sliders 28 slidably embedded in the slide groove 27, a clamping plate 29 fixed at the bottom of the slider 28, and a third motor 30 installed at the end of the connecting plate 26 for driving the bidirectional screw rod 31 to rotate. The pair of sliders 28 are symmetrically threaded with the bidirectional screw rod 31. The hydraulic arm 3 is started to push the connecting plate 26 downward to abut against the back side of the mold. The third motor 30 is started to drive the bidirectional screw rod 31 to rotate, driving the pair of sliders 28 to drive the pair of clamping plates 29 to approach each other to clamp the mold. Then, the hydraulic arm 3 is started to contract, and the pair of clamping plates 29 clamps the mold. The precast concrete part is retained on the operating table 1 under the action of its own gravity, thereby realizing the demoulding of the precast concrete part.

[0029] As a preferred technical solution in this embodiment, a collecting box 14 is provided at one end of the top of the operating table 1 away from the flip plate 6, and a driving frame 15 for driving the top plate 2 to translate is provided on the operating table 1. The driving frame 15 includes columns 10 vertically fixed at the four corners of the operating table 1, and a fixing plate 11 is fixed to the tops of the two columns 10 located at the same end of the operating table 1. Two first one-way screws 12 are rotatably installed side by side between a pair of fixing plates 11, and the top plate 2 is threadedly sleeved with the first one-way screw 12. A first motor 13 for driving the first one-way screw 12 to rotate is installed on one of the fixing plates 11. After the clamping mechanism 4 clamps the mold, the first motor 13 is started to drive the first one-way screw 12 to rotate, driving the top plate 2 to move above the collecting box 14, and the mold can fall off into the collecting box 14 for collection.

[0030] Working principle: When in use, the mold with the formed concrete prefabricated part is placed horizontally on the flip plate 6, the second motor 20 is started to drive the second one-way screw 19 to rotate, and the slide 18 is driven to move toward the operating table 1. At this time, the inner arm 22 pushes against one end of the inner part of the slide cavity 24, and the sleeve arm 23 is continuously pushed to force the flip plate 6 to flip, driving the concrete mold to flip onto the operating table 1, and then the hydraulic arm 3 is started to push the connecting plate 26 down to abut against the back of the mold, and the third motor 30 is started to drive the two-way screw 31 to rotate, driving a pair of sliders 28 to drive a pair of clamping plates 29 to move closer to each other to clamp the mold, and then the hydraulic arm 3 is started to contract, and a pair of clamping plates 29 are driven to move closer to each other to clamp the mold. The plate 29 clamps the mold, and the precast concrete part is retained on the operating table 1 under the action of its own gravity. The clamped mold drives the first one-way screw 12 to rotate by starting the first motor 13, driving the top plate 2 to move above the collection box 14, and the mold can fall off to the collection box 14 for collection, thereby realizing the demoulding and unloading of the precast concrete part. The overall structure is reasonable, and the automatic demoulding and unloading of the precast concrete part can be realized. Compared with the manual demoulding method, the demoulding efficiency is improved and the labor is saved. Compared with the demoulding method of clamping the mold for demoulding, the demoulding method of clamping the concrete part is easier to demould, and the problem of concrete clamping and falling damage is avoided.
