Description

Technical Field

[0001] This utility model relates to the field of trench cover demolding technology, specifically a trench cover demolding bracket. Background Technology

[0002] Drainage ditch covers, also known as "drainage covers," "manhole covers," or "sewage well covers," are plate-shaped materials used to cover drainage ditches. They are usually made of concrete and guide water flow smoothly into the drainage system, preventing rainwater or sewage from accumulating on the ground and reducing the impact of water accumulation on the surrounding environment. For example, in heavy rain, they can quickly drain water from roads and prevent water accumulation from affecting traffic.

[0003] Chinese patent discloses an auxiliary demolding platform for precast cover plates of cable troughs in tunnels (authorization announcement number CN217257161U), which includes an upper support for assisting demolding and lower support legs for supporting the upper support. The upper support is a grid-shaped frame structure, including two parallel horizontal beams and two parallel longitudinal beams, with the longitudinal beams located above the horizontal beams. The upper end faces of the two longitudinal beams are used to support the precast cover plate mold box and are fixed with two right-angle limiting ribs to limit the position of the precast cover plate mold box. An accommodating space adapted to the precast cover plate is formed between the inner side walls of the two longitudinal beams.

[0004] When using the above-mentioned device for demolding, the device involves manually lifting and releasing the precast cover mold box, allowing the precast cover mold box and the precast cover to fall freely and demold by inertia. Even if the device is equipped with rubber pads for cushioning, the impact force generated during the fall may cause the cover's edges and corners to dent, crack, or chip. This is especially true for precast cover plates that are heavy or made of brittle materials, where the risk of damage is higher, affecting the quality of the finished product. Furthermore, it is difficult to precisely control the falling height manually. If the height is too low, insufficient inertia may lead to incomplete demolding, requiring repeated operations and exacerbating the wear and tear on the cover and mold box. Therefore, this utility model provides a trench cover demolding bracket to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a demolding bracket for a drainage ditch cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A demolding bracket for a drainage ditch cover includes a template. An extrusion plate for defining the template is slidably connected above the template. A fixing plate is slidably connected above the extrusion plate. Vertical plates are fixedly connected to both ends of the bottom of the fixing plate. An unfolding structure for pushing the extrusion plate downward is rotatably connected to the bottom of the fixing plate, and the unfolding structure pushes the extrusion plate to fit against the top of the template. Limiting strips are rotatably connected inside the two vertical plates near the template. An expansion structure for limiting the limiting strips is rotatably connected to the inner cavity of both vertical plates, and the angle of the limiting strips is fixed by the expansion structure.

[0008] As a further embodiment of this utility model, the outer wall of the extrusion plate is fixedly connected with a ring-shaped handle for easy gripping, and the bottom of both upright plates is fixedly connected with rubber strips for bottom protection of the upright plates.

[0009] As a further embodiment of this utility model, the unfolding structure includes a main rod, the top of which is connected to the bottom of a fixed plate, a secondary rod rotatably connected to one side of the main rod via a pivot, and sliding blocks rotatably connected to the bottom of the main rod and the top of the secondary rod via pins. The top of the pressing plate and the bottom of the fixed plate are provided with grooves for providing sliding for the sliding blocks.

[0010] As a further embodiment of this utility model, the expansion structure includes a push plate, which is rotatably connected to the inner cavity of the upright plate, and a lever plate is fixedly connected to the end of the push plate away from the limiting strip.

[0011] As a further embodiment of this utility model, an extension plate is fixedly connected to one side of each of the two upright plates, and a support plate is rotatably connected to the inner cavity of the extension plate. An extension rod for increasing friction is fixedly connected to the bottom of the support plate.

[0012] As a further embodiment of this utility model, the bottom of the extrusion plate is fixedly connected with an arc-shaped limiting plate for limiting the template. There are two arc-shaped limiting plates, and both arc-shaped limiting plates are located at the bottom end of the arc-shaped limiting plate near the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In use, this utility model fixes the template by moving the extrusion plate downwards and cooperating with the limiting strip. The operator applies force by gripping the ring handle, pushing the extrusion plate to rotate the upright plate and the support plate connected to the extension plate around the template. When the template rotates to the bottom and faces upwards, the cover plate formed inside the template naturally detaches from the template under its own weight, completing the demolding process. This achieves labor-saving, efficient, and safe demolding of the cover plate, effectively avoiding damage to the corners of the cover plate due to collisions. Moreover, it can be operated by only one person, reducing labor costs. In addition, the cover plate detaches from the template naturally by its own weight, without the need for manual knocking or prying, reducing the risk of corner breakage and improving the quality of the finished product. Overall, it achieves a labor-saving, efficient, and quality-assured demolding effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 In this embodiment of the utility model, a drainage ditch cover demolding support includes a template 1. The interior of the template 1 can be used to pour cement to form a drainage ditch cover. An extrusion plate 2 for limiting the template 1 is slidably connected above the template 1. A fixing plate 3 is slidably connected above the extrusion plate 2. Vertical plates 4 are fixedly connected to both ends of the bottom of the fixing plate 3. The inner cavities of the two vertical plates 4 are provided with square grooves 404 for limiting the sliding range of the extrusion plate 2. The extrusion plate 2 is slidably connected to the outer walls of the two vertical plates 4, and part of the extrusion plate 2 is slidably connected to the inner cavity of the square groove 404, so that when the extrusion plate 2 slides up and down, it can only slide up and down within the height range inside the square groove 404. The bottom of the fixing plate 3 is rotatably connected to an unfolding structure 6 for pushing the extrusion plate 2 down, and the unfolding structure 6 pushes the extrusion plate 2 to fit against the template 1. The top of template 1 is reinforced to prevent it from sliding downwards during flipping. Two vertical plates 4 are rotatably connected to a limiting strip 401 at their ends near template 1. Rollers 402 are rotatably connected to the inner cavities of both vertical plates 4. An inner groove 403 is provided at the end of each vertical plate 4 near template 1 to allow the limiting strip 401 to rotate. The limiting strip 401 is fixedly connected to the outer wall of the roller 402 and flips within the inner groove 403 as the roller 402 rotates. An expansion structure 5 is rotatably connected to the inner cavities of both vertical plates 4 to limit the limiting strip 401. The expansion structure 5 fixes the angle of the limiting strip 401, preventing it from shaking when the limiting strip 401 is stuck on the outer edge of template 1 during flipping, which could cause template 1 to fall and break. Specifically, when the template 1 is pushed under the extrusion plate 2, the expansion structure 5 pushes the limiting strip 401 to flip the outer edge of the template 1, so that the limiting strip 401 and the extrusion plate 2 cooperate to fix the template 1. The extrusion plate 2 drives the template 1 to flip to the bottom of the template 1 facing upwards, so that the pre-supported cover plate inside the template 1 can naturally detach from the template 1 by its own weight, without the need for manual knocking or prying, avoiding the laborious operation of traditional manual demolding, and reducing the risk of the cover plate falling off. In addition, before flipping, the unfolding structure 6 pushes the extrusion plate 2 down and fits against the top of the template 1, and the limiting strip 401 locks the outer edge of the template 1. The double fixation ensures that the template 1 does not slide or shake during the flipping process, and allows a single person to easily apply force through the ring handle 201.

[0022] Please see Figures 1-3The outer wall of the extrusion plate 2 is fixedly connected with a ring handle 201 for easy gripping, allowing the operator to easily apply a flipping force through the ring handle 201 to drive the extrusion plate 2 and the template 1 fixed on it to flip, without the need for multiple people to work together, thus improving the safety and convenience of the demolding process. The bottom of both upright plates 4 is fixedly connected with rubber strips 203 for bottom protection of the upright plates 4. When the upright plates 4 are flipped or moved, the rubber strips 203 can buffer the impact force generated by the contact between the upright plates 4 and the ground, reduce the loosening of the components of the support due to vibration, and at the same time avoid the wear caused by direct friction between the bottom of the upright plates 4 and the ground, thus extending the service life of the upright plates 4.

[0023] Please see Figure 1 and Figure 3 The unfolding structure 6 includes a main rod 601. The top of the main rod 601 is rotatably connected to the bottom of the fixed plate 3 via a pin. A secondary rod 602 is rotatably connected to one side of the main rod 601 via a pivot. The bottom of the secondary rod 602 is rotatably connected to the top of the extrusion plate 2 via a pin. Sliding blocks 603 are rotatably connected to the bottom of the main rod 601 and the top of the secondary rod 602 via pins. Sliding grooves 604 for providing sliding for the sliding blocks 603 are provided on the top of the extrusion plate 2 and the bottom of the fixed plate 3. Specifically, an electric push rod 605 for moving the sliding blocks 603 inside the extrusion plate 2 is fixedly connected to the top of the extrusion plate 2. A connecting plate 606 is fixedly connected to one end of the electric push rod 605 near the sliding block 603 inside the extrusion plate 2. The top of the inner cavity of the extrusion plate 2 is fixedly connected to a sliding groove 607 for providing sliding for the connecting plate 606. The sliding groove 607 communicates with the sliding groove 604 opened on the top of the extrusion plate 2, so that the connecting plate 606 passes through the sliding groove 604 and is fixedly connected to the sliding block 603 inside the extrusion plate 2. When the electric push rod 605 extends and retracts, it slides through the connecting plate 606 and the sliding block 603, thereby pushing the main rod 601 to flip, realizing the up and down movement of the extrusion plate 2. At the same time, the secondary rod 602 rotates to ensure that the extrusion plate 2 moves up and down smoothly, helping to disperse the pressure of the main rod 601 and prevent the extrusion plate 2 from tilting. When the extrusion plate 2 moves horizontally downward, it squeezes and fixes the top of the template 1, and when it moves upward, it relaxes the template 1 to facilitate the removal of the template 1.

[0024] Please see Figures 3-5The expansion structure 5 includes a push plate 501, which is rotatably connected to the inner cavity of the upright plate 4 and fixedly connected to the outer wall of the roller 402. The angle difference between the push plate 501 and the limiting strip 401 is 90°, so that when the push plate 501 drives the roller 402 to rotate, the limiting strip 401 flips synchronously and locks the outer edge of the template 1. A lever plate 502 is fixedly connected to the end of the push plate 501 away from the limiting strip 401. Specifically, the inner cavities of the two upright plates 4 are slidably connected to insert blocks 503 for limiting the push plate 501. A circular slot for cooperating with the insert block 503 is opened on the side wall of the push plate 501. The inner cavities of the two upright plates 4 are also provided with useful... A transverse groove 504 is provided for the sliding of the insert 503. A spring 505 for pushing the insert 503 into the push plate 501 is fixedly connected to the inner cavity of the transverse groove 504. A lever 506 for pushing the insert 503 to retract is fixedly connected to one end of the spring 505 near the push plate 501. The lever 506 is fixedly connected to the insert 503. When the push plate 501 is flipped downward to a vertical state, the spring 505 uses its own elastic force to push the insert 503 into the interior of the circular slot, fixing the angle of the push plate 501 and the limiting strip 401, preventing the limiting strip 401 from shaking and causing the template 1 to fall off during the flipping process, and avoiding damage to the cover plate due to falling.

[0025] Please see Figures 1-3 An extension plate 405 is fixedly connected to one side of each of the two upright plates 4. A support plate 406 is rotatably connected to the inner cavity of the extension plate 405. An extension rod 407 for increasing friction is fixedly connected to the bottom of the support plate 406. Specifically, multiple extension rods 407 are arranged in an array at the bottom of the support plate 406. When the extrusion plate 2 is flipped, it drives the upright plate 4 to flip around the support plate 406 via the extension plate 405. The multiple extension rods 407 at the bottom of the support plate 406 are inserted into the ground. The friction between the extension rods 407 and the ground and the support points formed by the multiple arrays provide a stable support for the entire flipping process. This prevents the extrusion plate 2 from sliding or tipping over due to uneven force during flipping, ensuring the stability of the extrusion plate 2 during flipping, reducing the risk of the cover plate losing corners due to shaking and collision with the ground, and indirectly improving the quality and safety of the operation.

[0026] Please see Figures 1-3 The bottom of the extrusion plate 2 is fixedly connected to an arc-shaped limiting plate 202 for limiting the template 1. There are two arc-shaped limiting plates 202, and both arc-shaped limiting plates 202 are located at the bottom of the end of the arc-shaped limiting plate 202 near the support plate 406. The arc-shaped limiting plates 202 limit the outer edge of the template 1 near the support plate 406. When the template 1 is flipped, the arc-shaped limiting plates 202 fit against the outer edge of the template 1 to form a lateral obstruction, directly offsetting the sliding force and preventing the template 1 from sliding to the bottom from below the extrusion plate 2 during rotation.

[0027] The working principle of this utility model is as follows: When using this invention, after the cement poured inside the template 1 has solidified and completely dried, the formed cover plate and template 1 can be pushed together to the bottom of the extrusion plate 2. By pressing the lever 502, the push plate 501 is pushed down, causing the limiting strip 401 to flip upward and lock the outer edge of the template 1. When the electric push rod 605 is driven to retract, it slides through the connecting plate 606 and the sliding block 603, thereby pushing the main rod 601 to flip, pushing the extrusion plate 2 to move down, extruding the top of the template 1, and cooperating with the limiting strip 401 to fix the template 1. Then, the operator applies force by gripping the ring handle 201, pushing the extrusion plate 2 to drive the upright plate 4 and the template 1 to flip around the support plate 406 connected by the extension plate 405. When the template 1 flips to the bottom and faces upward, the cover plate inside the template 1, which has solidified, naturally detaches from the template 1 under its own gravity to complete demolding. The operator then rotates the ring handle 201 again to apply force, pushing the extrusion plate 2 to rotate in the opposite direction and reset it for the next use.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
