[0002] In the field of construction engineering, thermal insulation core materials are key materials for improving the thermal insulation performance of buildings. The quality of their fixing and molding directly affects the overall thermal insulation effect and durability of the building.

[0003] Traditional methods of fixing insulation core materials mostly rely on manual operations or simple mechanical devices. These methods are not only inefficient, but also difficult to ensure the stability and uniformity of the insulation core materials during concrete pouring. Especially during the concrete pouring process, due to the difference in density and weight between the insulation core materials and the concrete, the insulation core materials often float, shift or even get damaged in the concrete, resulting in quality problems such as voids and cracks in the insulation layer, which seriously affects the insulation effect and service life of the building.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, when the mounting block just moves up, the mounting block moves up relative to the pin. When the mounting block moves up to the pin cap that abuts the pin, the mounting block continues to move up to drive the pressure plate to move up. When the mounting block does not abut the pin cap of the pin, the mounting block drives the mounting frame to move up through the tension spring, and the mounting frame drives the rectangular frame to move up, so that the rectangular frame presses the blocking belt on the port of the rectangular box, so that only a small amount of concrete can enter the rectangular box through the edge of the blocking belt. Subsequently, the mounting block continues to move up so that the tension spring is stretched to ensure that the mounting block The upward movement is not blocked, so the mounting block drives the pressure plate to move upward. At this time, the thermal insulation core material squeezed by the pressure plate recovers elastically. At the same time, the upward movement of the pressure plate generates negative pressure in the rectangular box. The negative pressure causes the concrete to enter the rectangular box through the slurry inlet holes on the retaining belt. At this time, the relative positions of the rectangular plate and the rectangular box remain unchanged. The vertical rod is in contact with the thermal insulation core material at this time, so that the concrete can enter the rectangular box and fill the gaps in the thermal insulation core material, thereby increasing the density of the thermal insulation core material and preventing the thermal insulation core material from floating in the concrete.

[0034] Both ends of the rectangular box 27 are connected to a swivel seat 3, and both sets of swivel seats 3 are rotatably connected to an electric swivel rod 31.

[0035] The lower surface of the rectangular plate 41 is connected to a vertical rod 42, which passes through the pressure plate 23 and abuts against the thermal insulation core material, so that the first hydraulic rod 21 is shortened to make the rectangular box 27 move upward relative to the vertical rod 42, so that the vertical rod 42 pushes the thermal insulation core material out of the rectangular box 27; when the rectangular box 27 moves upward, it can squeeze the elastic block 43 to make the rectangular box 27 close to the rectangular plate 41.

[0037] It also includes a steel bar feeding mechanism, which includes a vertical plate 5, which is a side plate of the mold 11. The upper part of the vertical plate 5 is connected to a horizontal plate 51, and a push plate 52 is slidably connected to the horizontal plate 51. A steel mesh is placed on the horizontal plate 51 between the push plate 52 and the mold 11. When the first hydraulic rod 21 is shortened, the push plate 52 pushes the steel mesh into the mold 11, and when the first hydraulic rod 21 is extended, the push plate 52 moves away from the mold 11.

[0038] The transverse plate 51 is connected to a third hydraulic rod 53 , a transmission pipe 534 is connected between the third hydraulic rod 53 and the second hydraulic rod 4 , and an output end of the third hydraulic rod 53 is connected to the push plate 52 .

The end of the round rod 532 is fixedly connected to the push plate 52, and an electric locking rod 533 is inserted into the cylinder body of the third hydraulic rod 53 and the cylinder 531; when the first hydraulic rod 21 is shortened for the first time, the electric locking rod 533 located in the cylinder 531 operates and locks the cylinder 531 and the round rod 532, so that the cylinder 531 and the round rod 532 are extended together, and when the first hydraulic rod 21 is shortened for the second time, the electric locking rod 533 located in the cylinder body of the third hydraulic rod 53 operates and locks the cylinder 531 to the cylinder body of the third hydraulic rod 53, so that the round rod 532 is extended.

An electric telescopic rod 536 is connected to the base 1, and the output end of the electric telescopic rod 536 is connected to the piston plate 537. A pipeline 538 is connected between the first piston cylinder 535 and the third hydraulic rod 53. When the first hydraulic rod 21 is extended, the electric telescopic rod 536 is shortened so that the excess hydraulic oil in the third hydraulic rod 53 is drawn into the first piston cylinder 535, so that the cylinder 531 or the round rod 532 can be completely retracted; the cross plate 51 is connected with a first piston cylinder 535, and the second piston cylinder 535 is connected with a second piston cylinder 535. There are two piston cylinders 54, in which a piston rod 55 is slidably connected, a spring 56 is connected between the piston rod 55 and the second piston cylinder 54, a fourth hydraulic rod 59 is connected between the cross plate 51 and the base 1, an oil transfer pipe 57 is connected between the fourth hydraulic rod 59 and the second piston cylinder 54, an oil extraction pipe 58 is connected to the second piston cylinder 54, and both the oil transfer pipe 57 and the oil extraction pipe 58 are provided with a one-way valve. When the push plate 52 slides back and forth, it can drive the piston rod 55 to slide on the second piston cylinder 54, so that the hydraulic oil enters the fourth hydraulic rod 59 to move the cross plate 51 upward.

[0041] The working principle of the fixing device of the thermal insulation core material provided in this embodiment is as follows:

[0042] When in use, the base 1 is placed on a flat ground, the mold 11 is placed on the base 1, and then the bracket 2 is installed on the base 1. The top of the vertical plate 5 constituting the side plate of the mold 11 exceeds the bottom plate of the mold 11 by a certain height in the initial state. The thermal insulation core material is placed in the rectangular box 27, and then the electric rotating rod 31 is controlled to rotate so that the blocking belt 32 closes the lower port of the rectangular box 27. At this time, the thermal insulation core material is in the rectangular box 27, and the first hydraulic rod 21 is controlled to extend. At this time, the first hydraulic rod 21 pushes the mounting block 22 to move downward, so that the mounting block 22 moves downward relative to the pin 24. When the mounting block 22 abuts against the pin cap of the pin 24, the mounting block 22 can drive the pressing plate 23 to move downward through the pin 24. At this time, the pressing plate 23 presses the thermal insulation core material on the blocking belt 32, and the blocking belt 32 is When pressed, the rectangular box 27 is driven to move downward. At this time, the L-shaped frame 44 on the rectangular box 27 pulls the rectangular plate 41, so that the second hydraulic rod 4 extends. When the first hydraulic rod 21 extends to a position close to the bottom wall of the mold 11, it stops extending. At this time, concrete is poured into the mold 11. When the concrete is not above the half height of the rectangular box 27, the first hydraulic rod 21 is controlled to shorten. At this time, the first hydraulic rod 21 drives the mounting block 22 to move upward. When the mounting block 22 just moves upward, the mounting block 22 moves upward relative to the pin 24. When the mounting block 22 moves up to abut the pin cap of the pin 24, the continued upward movement of the mounting block 22 will drive the pressure plate 23 to move upward. When the mounting block 22 is not abutted against the pin cap of the pin 24, the mounting block 22 drives the mounting frame 25 to move upward through the tension spring 251. The mounting frame 25 thus drives the rectangular frame 26 to move upward, so that the rectangular frame 26 presses the blocking belt 32 on the port of the rectangular box 27, so that only a small amount of concrete can enter the rectangular box 27 through the edge of the blocking belt 32, and then the mounting block 22 continues to move upward so that the tension spring 251 is stretched to ensure that the upward movement of the mounting block 22 is not blocked, so that the mounting block 22 drives the pressing plate 23 to move upward at this time, and the thermal insulation core material squeezed by the pressing plate 23 elastically recovers, and at the same time, the upward movement of the pressing plate 23 generates negative pressure in the rectangular box 27, and the negative pressure causes the concrete to enter the rectangular box 27 through the slurry inlet hole 33 on the blocking belt 32, while the relative position of the rectangular plate 41 and the rectangular box 27 remains unchanged at this time, and the vertical rod 42 abuts against the thermal insulation core material, so that the concrete can The first hydraulic rod 21 stops running when the pressing plate 23 moves up to the top wall of the rectangular box 27 and is about to touch the first hydraulic rod 21. At this time, the electric rotating rod 31 rotates so that the blocking belt 32 is stored, so that the port of the rectangular box 27 is opened and the thermal insulation core material can be separated from the rectangular box 27. Then the first hydraulic rod 21 continues to shorten, and the pressing plate 23 is driven to continue to move up and contact the top wall of the rectangular box 27. At this time, the power of the first hydraulic rod 21 is completely transmitted to the rectangular box 27, so that the rectangular box 27 moves up. The extension and contraction of the second hydraulic rod 4 has resistance, so that when the rectangular box 27 moves up, it can squeeze the elastic block 43. At this time, the elastic block 43 is deformed.Then the vertical rod 42 moves downward relative to the rectangular box 27, so that the heat-insulating core material is pushed out of the rectangular box 27, so that the heat-insulating core material no longer moves relative to the mold 11;

[0043] When the first hydraulic rod 21 is shortened to the shortest, the rectangular box 27 is moved out of the mold 11, and then the first hydraulic rod 21 stops running. After the first hydraulic rod 21 maintains the shortened state, the elastic block 43 elastically recovers, and at this time the pin 24 slides down to the lowest stroke relative to the mounting block 22, so that the elastic recovery of the elastic block 43 causes the rectangular plate 41 to be pushed upward, and at this time the second hydraulic rod 4 is further shortened, so that the vertical rod 42 slides up relative to the rectangular box 27, ensuring that the placement of the thermal insulation core material is not affected by the vertical rod 42. After the thermal insulation core material is placed in the rectangular box 27 in the lower space of the pressing plate 23, the electric rotating rod 31 is controlled to rotate, so that the blocking belt 32 closes the port of the rectangular box 27, so that the thermal insulation core material is fixed in the rectangular box 27, and then the first hydraulic rod 21 is extended again;

[0044] Since the casting of the insulation board requires multiple layers of insulation core material, the extension length of the first hydraulic rod 21 is gradually reduced to adapt to the continuous casting of the thicker insulation board;

[0045] As the extension length of the first hydraulic rod 21 decreases, the length of the second hydraulic rod 4 also decreases synchronously. In this embodiment, when the second hydraulic rod 4 is shortened, the hydraulic oil inside it is transmitted to the third hydraulic rod 53 through the transmission pipe 534. When the first hydraulic rod 21 is shortened for the first time, the second hydraulic rod 4 changes from the longest state to the shortest state, so that the second hydraulic rod 4 can completely transmit the hydraulic oil to the third hydraulic rod 53. At this time, the cylinder 531 and the round rod 532 in the third hydraulic rod 53 are locked by the electric locking rod 533, so that a large amount of hydraulic oil can push the third hydraulic rod 53 to fully extend, thereby causing the push plate 52 to be driven to move and push the steel mesh into the mold 11 and be on the upper part of the thermal insulation core material that has just been released. The inner wall of the mold 11 is provided with a groove, and the steel mesh slides into the groove, so that the vertical position of the steel mesh is fixed. When the first hydraulic rod 21 is shortened for the first time and then extended, due to the first hydraulic The extension length of the rod 21 is reduced, and the generated length of the second hydraulic rod 4 is reduced at this time, so that the second hydraulic rod 4 will not completely extract the hydraulic oil in the third hydraulic rod 53, and the push plate 52 is not completely reset at this time. At this time, when the second hydraulic rod 4 is extended or after extension, the electric telescopic rod 536 is shortened, so that the piston plate 537 moves downward, and the first piston cylinder 535 extracts the residual hydraulic oil in the third hydraulic rod 53 through the pipeline 538, and then the third hydraulic rod 53 is shortened to the shortest state, and the push plate 52 can be reset at this time. After the push plate 52 is reset, the cylinder 531 is locked on the cylinder body of the third hydraulic rod 53 by the electric locking rod 533, and the diameter of the round rod 532 is reduced compared with the diameter of the cylinder 531, so that when the second hydraulic rod 4 is shortened and reduced, although the amount of hydraulic oil entering the third hydraulic rod 53 is reduced, it can still ensure that the round rod 532 extends to a length sufficient to completely push the steel mesh into the mold 11;

[0046] The structure of the electric lock rod 533 can be set with reference to the movement mechanism of the solenoid valve stem. If the thickness of the insulation board to be cast is relatively high, so that the extension length of the first hydraulic rod 21 is gradually reduced, multiple cylinders 531 can be set in the third hydraulic rod 53, so that the diameters of the cylinder 531 and the round rod 532 extending out of the third hydraulic rod 53 are gradually reduced, so as to adapt to the processing of insulation boards of different thicknesses;

[0047] Since the above structure ensures that the reciprocating sliding stroke of the push plate 52 remains unchanged, the push plate 52 can push the piston rod 55 into the second piston cylinder 54 to a fixed stroke, thereby ensuring that when the push plate 52 pushes the steel mesh into the mold 11 and resets, the medium in the second piston cylinder 54 can be transferred to the fourth hydraulic rod 59, so that the fourth hydraulic rod 59 gradually extends, so that the vertical plate 5 and the horizontal plate 51 are synchronously and gradually moved up to adapt to the increasing thickness of the insulation board;

[0048] A valve is provided on the fourth hydraulic rod 59 so that the hydraulic oil in the fourth hydraulic rod 59 can be discharged so that the fourth hydraulic rod 59 can be shortened.

[0049] Example 2, reference Figure 7 The difference from Example 1 is that a connecting rod 6 is hinged on the base 1, and the output end of the third hydraulic rod 53 is connected to a sleeve frame 61, which is sleeved on the connecting rod 6. A through groove 62 is provided on the connecting rod 6, and a sliding rod 63 is connected to the push plate 52. The sliding rod 63 slides in the through groove 62. When the third hydraulic rod 53 is extended or retracted, it can drive the connecting rod 6 to swing, so that the connecting rod 6 pushes and pulls the push plate 52 to approach or move away from the mold 11 through the sliding rod 63.

[0050] An electric push rod 64 is connected between the cross plate 51 and the base 1. After the third hydraulic rod 53 contracts, the electric push rod 64 extends to move the cross plate 51 upward, so that the push plate 52 moves upward synchronously with the cross plate 51, and the slide rod 63 slides in the through groove 62 to make the push plate 52 further away from the mold 11.

[0051] In this embodiment, the extension and retraction of the second hydraulic rod 4 causes the hydraulic oil to be transmitted to the third hydraulic rod 53 through the transmission pipe 534, so that the third hydraulic rod 53 is extended and retracted. When the third hydraulic rod 53 is extended, the connecting rod 6 is pushed to swing in the direction of the mold 11 through the sleeve frame 61. At this time, the connecting rod 6 pushes the push plate 52 to approach the mold 11 through the sliding rod 63, so that the steel mesh is pushed into the mold 11. When the third hydraulic rod 53 is shortened, the connecting rod 6 is pulled to swing in the direction away from the mold 11 through the sleeve frame 61, and the extension length of the first hydraulic rod 21 decreases. Therefore, the third hydraulic rod 53 will not be completely shortened. At this time, the connecting rod 6 drives the push plate 52 to be a certain distance away from the original position. After the connecting rod 6 swings back to rest, the electric push rod 64 extends, so that the cross plate 51 moves up, and the cross plate 51 drives the push plate 52 to move up synchronously. Since the connecting rod 6 is in an inclined state, the sliding rod 63 slides in the through groove 62 of the connecting rod 6, so that the push plate 52 is further away from the mold 11, ensuring that the push plate 52 returns to its original position. The distance between the push plate 52 and the mold 11 ensures that there is enough space for the steel mesh to be placed.

[0052] The sliding rod 63 and the swing point of the connecting rod 6 gradually move away from each other, and the moving distance of the connecting rod 6 away from the swing point gradually increases, so that when the telescopic stroke of the third hydraulic rod 53 is reduced, the upward movement of the cross plate 51 can still make the push plate 52 slide a sufficient stroke so that the steel mesh can be pushed into the mold 11.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
