Description

Technical Field

[0001] The invention belongs to the field of automated machinery, and in particular relates to a mold turning and demoulding device for railway precast concrete components. Background Art

[0002] Precast concrete parts are semi-finished or finished components that are pre-processed and formed at a prefabrication plant or construction site using concrete materials according to the requirements of design drawings. After reaching a certain strength, they are transported to the construction site for direct installation.

[0003] After the precast concrete parts are formed, the workers need to separate the mold and the precast concrete parts. The separation process of the mold and the precast concrete parts is called demoulding. Manual demoulding is to manually move the mold box with the precast concrete parts to an iron frame or steel frame, with the mold box opening facing downward, and repeatedly hit the iron frame or steel frame through the edge of the mold box, so that the precast concrete parts are separated from the mold box and fall to the ground.

[0004] At present, all small prefabricated component molds across the country use ABS plastic molds. The traditional demoulding process mainly uses manual work to repeatedly collide the edge of the mold with an iron frame or a steel frame to separate the prefabricated concrete components from the mold box, which can easily cause damage to the mold, chipping of components, high scrap rate and low demoulding efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a railway precast concrete component mold flipping and demoulding device in view of the above-mentioned deficiencies in the prior art, thereby reducing the burden on personnel and realizing the automation of demoulding of the flipping machine.

[0006] The technical solution adopted by the present invention is: a railway precast concrete component mold flipping and demolding device, comprising a base, a mounting frame arranged in the middle of the upper surface of the base, a first flip bracket with one end hinged to the top of the mounting frame, and a second flip bracket with one end hinged to the top of the mounting frame and arranged opposite to the first flip bracket, the first flip bracket is hinged to the outer side of one end close to the mounting frame with a push rod, the mounting frame is also provided with a demolding lifting bracket at one end hinged to the mounting frame, the middle part of the lower surface of the first flip bracket is connected to the upper surface of the base through a first hydraulic cylinder, the middle part of the lower surface of the second flip bracket is connected to the upper surface of the base through a second hydraulic cylinder, the middle part of the lower surface of the demolding lifting bracket is connected to the upper surface of the base through a lifting hydraulic cylinder, a vibration motor is provided on the lower surface of the demolding lifting bracket, and a flip groove for the second flip bracket and the lifting hydraulic cylinder to pass through is provided on the inner side of the demolding lifting bracket.

[0007] In one of the embodiments, the first flip bracket includes several first flip steel beams arranged along the length direction of the base and hinged to the mounting frame, a first hydraulic mounting bracket is provided in the middle of the lower surface of the first flip steel beams, and the piston rod end of the first hydraulic cylinder is connected to the first hydraulic mounting bracket.

[0008] In one of the embodiments, each of the first flip steel beams includes a first beam body, and a limiting guide portion is provided at one end of the first beam body close to the mounting bracket.

[0009] In one of the embodiments, the second flip bracket includes several second flip steel beams arranged along the length direction of the base and hinged to the mounting frame, a second hydraulic mounting bracket is provided in the middle of the lower surface of several of the second flip steel beams, and the piston rod end of the second hydraulic cylinder is connected to the second hydraulic mounting bracket.

[0010] In one embodiment, each of the second flip steel beams includes a second beam body, and a limiting portion is provided at one end of the second beam body close to the mounting bracket.

[0014] 2. Solve the demoulding process. When demoulding the precast concrete parts, the mold box of the precast concrete parts needs to be turned over and placed upside down so that the mold opening faces downward. However, the precast concrete parts are heavy and difficult to turn over. The precast concrete parts are tightly bonded to the mold, making demoulding difficult. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, each of the first flip steel beams 31 includes a first beam body 311 , and a limiting guide portion 312 is provided at one end of the first beam body 311 close to the mounting bracket.

[0029] In this embodiment, the second flip bracket 4 includes several second flip steel beams 41 arranged along the length direction of the base 1 and hinged to the mounting frame 2, and a second hydraulic mounting bracket 42 is provided in the middle of the lower surface of the several second flip steel beams 41, and the piston rod end of the second hydraulic cylinder 7 is connected to the second hydraulic mounting bracket 42.

[0030] In this embodiment, each of the second flip steel beams 41 includes a second beam body 411 , and a limiting portion 412 is provided at one end of the second beam body 411 close to the mounting bracket.

[0031] In this embodiment, the demoulding lifting bracket 5 includes a lifting bracket body 51 hinged to the mounting frame 2, and limit plates 52 are provided on the outer sides of both ends of the lifting bracket. A lifting hydraulic mounting bracket 53 is provided on the lower surface of the lifting bracket body 51, and the piston rod end of the lifting hydraulic cylinder 8 is connected to the lifting hydraulic mounting bracket 53.

[0032] In this device, the mounting frame 2 is composed of two steel plates and a steel beam connecting the two steel plates. The first hydraulic cylinder 6, the second hydraulic cylinder 7 and the lifting hydraulic cylinder 8 are arranged between the two steel plates. The top of the mounting frame 2 is provided with bearings respectively hinged to the first flip bracket 3, the second flip bracket 4 and the demoulding lifting bracket 5. The first flip bracket 3, the second flip bracket 4 and the demoulding lifting bracket 5 are all hingedly connected by passing round steel through the bearings to realize rotation.

[0033] The first flip steel beam 31 of the first flip bracket 3 and the second flip steel beam 41 of the second flip bracket 4 are both welded by steel plates, and the first hydraulic mounting bracket 32 ​​and the second hydraulic mounting bracket 42 are both round steels, which pass through the first flip steel beam 31 and the second flip steel beam 41 to form the first flip bracket 3 and the second flip bracket 4. The shapes and sizes of the first flip bracket 3, the second flip bracket 4 and the demoulding support bracket 5 can be determined according to the actual situation of the concrete component to be demoulded, and are not limited to the shapes in the drawings. At the same time, the number, shape and size of the first flip steel beam 31 and the second flip steel beam 41 are also determined according to the actual situation of the concrete component to be demoulded, and are not limited to the shapes in the drawings.

At the same time, the models and parameters of the first hydraulic cylinder 6, the second hydraulic cylinder 7, the lifting hydraulic cylinder 8 and the vibration motor 9 are determined according to the actual situation of the concrete component to be demoulded.

[0035] The limiting guide part 312 at one end of the first beam body 311 is used to limit and guide the un-demolded precast concrete component. Its structure only needs to ensure that the un-demolded precast concrete component will not slide when the first flip bracket 3 flips, and does not block or jam the un-demolded precast concrete component when the second flip bracket 4 receives the un-demolded precast concrete component, and is not limited to the structure in the attached drawings.

[0036] This device is used for mold flipping and demoulding of railway precast concrete components, and there is a lifting gantry on top of it for cooperating with lifting. When working, the second hydraulic cylinder 7 lifts the second flip bracket 4 to the vertical starting position; when the precast component is placed on the flip bracket through the gantry, the first hydraulic cylinder 6 lifts the first flip bracket 3 to flip 90° to the vertical position, so that the first flip bracket 3 and the second flip bracket 4 clamp the precast component; the second hydraulic cylinder 7 retracts to flip the second flip bracket 4 to the horizontal position. During this process, the push rod 11 slides from the back of the mold and presses against the side of the mold. The first hydraulic cylinder 6 lifts, and the push rod 11 pushes the mold away from the limit part 412 of the second flip bracket 4. The precast component falls onto the demoulding support bracket 5; the vibration motor vibrates to separate the precast component mold from the concrete; the lifting hydraulic cylinder 8 contracts to lower the demoulding support bracket 5, and the demoulding is completed by removing the precast component.
