[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] Currently, with economic development and social progress, rectangular precast blocks for slope protection in highway construction are typically produced in a centralized manner. The precast blocks are poured and cured in standard rectangular formwork, in line with the production philosophy of "four savings and one environmental protection," saving labor costs, conserving land, and effectively ensuring the uniformity of precast component quality. After curing, the rectangular precast blocks need to be demolded. Currently, demolding is usually done manually using simple tools such as wooden sticks and steel bars to reverse the rectangular formwork and perform knocking and prying operations to remove the formwork.

[0037] However, because the process of reversing the template each time during manual operation is uncontrollable, it is easy to damage the precast components and reduce the yield. In addition, manual template reversal and demolding result in high labor intensity for workers and are time-consuming and labor-intensive.

[0038] To address the aforementioned technical problems, this utility model provides a demolding device for rectangular precast components, suitable for demolding construction of rectangular precast blocks, facilitating the reversal and demolding of rectangular groove templates, thereby reducing the labor intensity of workers.

[0039] The following describes in detail the overall structure, working principle, and technical effects of the demolding device for rectangular preforms provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0040] Please refer to Figure 1 and Figure 2 The demolding device for rectangular precast components includes a support bracket 100, a holding assembly 200, a supporting assembly 300, and a reversing assembly 400. The support bracket 100 provides a mounting carrier for the other components. The support bracket 100 is a hollow rectangular plate structure with a cavity in its center for the precast block to pass through. Furthermore, the support bracket 100 has a first state and a second state. Referring to the attached drawings... Figure 1 This is a structural diagram of the support bracket 100 in its first state. Figure 2 This is a schematic diagram of the second state of the support bracket 100. The support bracket 100 has a rotation axis 110. In this embodiment, the rotation axis 110 of the support bracket 100 coincides with the axis of symmetry along the length of the support bracket 100. The gripping component 200 has a U-shaped rod structure and two support arms 210. The ends of the two support arms 210 are rotatably connected to the two ends of the support bracket 100, and the rotation axis of the support arms 210 coincides with the rotation axis 110 of the support bracket 100, thereby allowing the gripping component 200 to rotate relative to the rotation axis 110 of the support bracket 100. Supporting components 300 are provided at both ends of the support bracket 100. The two supporting components 300 are respectively close to the two support arms 210, and a receiving space 310 for accommodating the rectangular groove template is formed between the two supporting components 300. A reversing component 400 is mounted on the support bracket 100. When subjected to external force, the reversing component 400 cooperates with the holding component 200 to reverse the support bracket 100 180° from the first state to the second state. Furthermore, the rectangular groove template is located on the support bracket 100, and when the support bracket 100 is in the first state, the rectangular groove template is supported between the two abutting components 300 with its opening facing upwards. When the support bracket 100 reverses the rectangular groove template to the second state, the rectangular groove template is supported on the support bracket 100 with its opening facing downwards, and the precast blocks inside the rectangular groove template fall through the cavity.

[0041] By setting up a support bracket 100 and abutment components 300, the support bracket 100 is moved to the rectangular groove template containing precast blocks in the first state, so that the rectangular groove template is located in the accommodating space 310 between the two abutment components 300. At this time, the worker holds the holding component 200 and applies external force to the support bracket 100. With the cooperation of the reversing component 400, the support bracket 100 drives the rectangular groove template to reverse 180° to obtain the second state. At this time, the opening of the rectangular groove template faces the direction, and the precast blocks detach from the template under the action of gravity and fall from the cavity, thereby realizing the reversal and demolding of the rectangular groove template. There is no need for the worker to manually reverse the rectangular groove template, reducing the labor intensity of the worker. At the same time, the rectangular blocks are demolded and fall from the same height each time they are demolded, avoiding uncontrollable impacts of the template when manually reversing, and improving the yield of precast parts.

[0042] Please refer to Figure 1 and Figure 2 A rectangular groove template generally includes a groove body and a groove eave located at the opening of the groove body and protruding from the opening. Based on this, in some optional embodiments, the supporting assembly 300 includes a support plate, which is a rectangular plate. Each of the two support plates has a receiving groove 320 on one opposite side. The receiving groove 320 is used to receive and support the groove eave of the rectangular groove template. A receiving space 310 is formed between the support plate and the support bracket 100. Furthermore, when the support bracket 100 is in the first state, the support plate is located below the support bracket 100.

[0043] By setting a bearing plate, when demolding the rectangular groove template, the moving support bracket 100 is moved until the groove edge of the rectangular groove template is located in the receiving groove 320, so that the bearing plate supports the rectangular groove template during the subsequent reversal of the support bracket 100.

[0044] Please refer to Figure 1 - Figure 3 To facilitate the reversal of the support bracket 100, in this embodiment, the reversing component 400 has an arc-shaped reversing surface 410, which extends to both sides of the support bracket 100. When the support bracket 100 is driven to reverse, the reversing component 400 rotates accordingly, and different positions of the reversing surface 410 abut against the ground. By setting the arc-shaped reversing surface 410, the arc-shaped reversing surface 410 always abuts against the ground when the support bracket 100 rotates, making the rotation of the support bracket 100 smooth and effortless, and facilitating the rotation of the support bracket 100.

[0045] Please refer to Figure 1 - Figure 3In this embodiment, the reversing component 400 includes a semi-circular plate with its axis of rotation parallel to the rotation axis 110. The two ends of the semi-circular plate are located on the upper and lower sides of the support bracket 100, respectively, so that when the support bracket 100 reverses from the first state to the second state, the reversing surface 410 of the semi-circular plate remains in contact with the ground. In other optional embodiments, the reversing component 400 may include a circular plate. Furthermore, to make the rotation of the support bracket 100 easier, the reversing component 400 may also include rolling bearings. It is sufficient that the reversing surface 410 of the reversing component 400 extends to both the upper and lower sides of the support bracket 100; the specific structural form of the reversing component 400 is not limited in this invention.

[0046] Please refer to Figure 1 and Figure 2 In this embodiment, the reversing component 400 also has a first support portion 420. When the support bracket 100 is in the first state, the first support portion 420 is located at the bottom end of the reversing component 400. At this time, the first support portion 420 plays the role of supporting the support bracket 100 so that the support bracket 100 can move onto the rectangular groove template and cooperate with the rectangular groove template.

[0047] In this embodiment, taking the reversing component 400 as a semi-circular plate as an example, when the support bracket 100 is in the first state, the first support portion 420 is located at the bottom of the semi-circular plate. It can be understood that the height of the support bracket 100 is determined by the diameter of the semi-circular plate. Therefore, for rectangular groove templates of different sizes, semi-circular plates of different diameters can be selected so that when the support bracket 100 is in the first state, the receiving groove 320 on the bearing plate is directly opposite the groove edge of the rectangular groove template in the horizontal direction, thereby facilitating the movement of the support bracket 100 to engage with the rectangular groove template.

[0048] Please refer to Figure 1 and Figure 2 In this embodiment, a support component 500 is provided at the end of the support bracket 100 away from the reversing component 400, and a second support portion 430 is provided at the end of the reversing component 400 away from the first support portion 420. When the support bracket 100 is in the second state, the support component 500 and the second support portion 430 jointly support the support bracket 100. By providing the second support portion 430 and the support component 500, when the support bracket 100 is in the second state, the rectangular groove template is located above the support bracket 100 with its opening facing downwards. The precast block falls off the rectangular groove template under the action of gravity, which facilitates the demolding of the precast block. During the demolding process, the second support portion 430 and the support component 500 can always provide a good supporting effect.

[0049] Please refer to Figure 1 - Figure 3 In some optional embodiments, the reversing component 400 also has a supporting surface 440 on the side facing the rotation axis 110. When the support bracket 100 is reversed from the first state to the second state, the reversing component 400 is located at the bottom of the demolding device. The supporting surface 440 is used to support the rectangular groove template, thereby cooperating with the supporting component 300 to limit and support the rectangular groove template on the support bracket 100, preventing the rectangular groove template from sliding downward and detaching from the support bracket 100 under the action of gravity.

[0050] Please refer to Figure 1 and Figure 2 In some optional embodiments, a first limiting member 450 parallel to the rotation axis 110 is provided on the reversing assembly 400, and a second limiting member 510 parallel to the rotation axis 110 is provided on the support assembly 500. The first limiting member 450 and the second limiting member 510 are respectively located on both sides of the support assembly 500 and are both used to abut against the support arm 210.

[0051] Among them, such as Figure 1 When the support bracket 100 is in the first state, the first limiting member 450 is located below the support bracket 100, the second limiting member 510 is located above the support bracket 100, and the support arm 210 abuts against the lower part of the second limiting member 510. At this time, the support bracket 100 is supported from below by the first supporting part 420, and supported from above by the abutment between the support arm 210 and the second limiting member 510. The operator holds the gripping component 200 to keep the support bracket 100 horizontal. The operator drags the demolding device to the rectangular groove template through the gripping component 200 to facilitate engagement with the rectangular groove template. Simultaneously, as the support bracket 100 rotates from the first state to the second state, the operator raises the gripping component 200. Due to the abutment between the support arm 210 and the second limiting member 510, the support bracket 100 is rotated. After the support bracket 100 rotates to a certain angle, by applying a certain external force to the support bracket 100 (such as stepping on the edge of the support bracket 100), the support bracket 100 is further rotated (rotated to the point where...). Figure 3 (State 1), after which the support bracket 100 completely reverses to the second state under the action of gravity.

[0052] like Figure 2 When the support bracket 100 is in the second state, the first limiting member 450 is located above the support bracket 100, and the second limiting member 510 is located below the support bracket 100. By setting the first limiting member 450 and the second limiting member 510, in cooperation with the holding assembly 200, they play a role in reversing and limiting the support arm 210. At the same time, in the first state, they cooperate with the holding assembly 200 to maintain the posture of the demolding device, which is convenient for operation in actual production.

[0053] Please refer to Figure 1 and Figure 2 In some optional embodiments, a rotating shaft 120 is provided on both sides of the support bracket 100, and the axis of the rotating shaft 120 coincides with the rotation axis 110. A sleeve 211 is provided on the support arm 210 and rotatably fitted with the rotating shaft 120, thereby allowing the support arm 210 to be rotatably mounted on the support bracket 100. In other optional embodiments, a hinge or articulated seat structure can also be used to rotatably mount the support arm 210 on the support bracket 100, and this utility model does not limit this.

[0054] Please refer to Figure 1 and Figure 2 In some optional embodiments, two support components 500 and two reversing components 400 are arranged side by side on the support bracket 100 along the direction of the rotation axis 110. This improves the support and rotation effect on the support bracket 100, and makes the demolding device subjected to uniform force, resulting in good structural strength and stability.

[0055] In summary, the implementation principle of the demolding device for rectangular precast parts provided by this utility model is as follows: By setting up a support bracket 100 and abutment components 300, the support bracket 100 is moved to the rectangular groove template containing the precast blocks in the first state, so that the rectangular groove template is located in the accommodating space 310 between the two abutment components 300. At this time, the worker holds the holding component 200 and applies external force to the support bracket 100. With the cooperation of the reversing component 400, the support bracket 100 drives the rectangular groove template to reverse 180° to obtain the second state. At this time, the opening of the rectangular groove template faces the direction, and the precast blocks detach from the template and fall from the cavity under the action of gravity, thereby realizing the reversal and demolding of the rectangular groove template, reducing the labor intensity of workers, avoiding uncontrollable impacts of the template during manual reversal, and improving the yield of precast parts.

[0056] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
