Description

Technical Field

[0001] This utility model relates to the field of concrete pouring, and in particular to a demolding device for concrete pouring cover plates. Background Technology

[0002] Concrete cover slabs are common components in building and municipal engineering projects (such as drainage ditch covers and cable trench covers), and demolding is a crucial step in their production process. After the concrete is poured and reaches a certain strength, the hardened cover slab must be separated from the mold box before subsequent curing, transportation, and installation can proceed.

[0003] Currently, the production of large-scale concrete components mainly involves demolding in specialized production plants using large-scale specialized equipment. This equipment is often used in large-scale production sites, such as precast component plants. These devices typically employ hydraulic drive, mechanical tilting, and other principles, using preset programs to control the tilting or vibration of the mold box to separate the cover plate from the mold box. They are characterized by high efficiency and a high degree of automation.

[0004] However, for concrete cover plates, the site is usually selected around the construction site, and the concrete is poured into a basin-shaped mold by a concrete mixer truck for on-site production. Such on-site production often does not have the conditions for using large demolding equipment, and mainly relies on manual demolding: the operators usually work together to use simple tools such as crowbars and hammers to first pry the edge of the mold box to loosen the cover plate, and then work together to flip the mold box to pour out the cover plate. This requires a lot of manpower and the demolding efficiency is low. Summary of the Invention

[0005] This utility model addresses the problem of inconvenient demolding when pouring concrete drainage ditch cover components around construction sites due to the lack of specialized equipment. It provides a demolding device for poured concrete cover slabs.

[0006] To solve the above problems, the technical solution adopted by this utility model is a concrete cover plate demolding device, including a frame, the frame being rectangular, and a fixing structure for connecting the mold box within the frame; front support legs are provided on the bottom surface of the two front corners of the frame, and lower crossbars are provided on the opposite sides of the two front support legs; rear columns are provided on the top surface of the two rear corners of the frame, and upper crossbars are provided on the opposite sides of the two rear columns; swing rods are hinged to both sides of the frame, and the swing rods are located below the upper crossbars. This solution designs a device for assisting in the demolding of concrete cover plates. The mold box is fixed in the frame by the fixing structure, and then the swing rod is flipped forward, pushing the upper crossbar upward. The frame flips forward with the lower end of the front support legs as a fulcrum, thus inverting the mold box onto the ground. Simultaneously, the vibration causes the poured cover plate to be poured out, completing the demolding. Then, the swing rod is flipped backward, and the frame is reset by the lower crossbar. This device is convenient and quick to use, and is suitable for manufacturing and use in sites lacking large demolding equipment.

[0007] As a preferred embodiment of a concrete casting slab demolding device, the frame includes two parallel side beams. A front connecting beam and a rear connecting beam are provided between the two side beams. The two ends of the front connecting beam are fixedly connected to the front ends of the two side beams, and the two ends of the rear connecting beam are fixedly connected to the rear ends of the two side beams. The fixing structure includes two sliding grooves, which are arranged on opposite surfaces of the two side beams. The sliding grooves are used to fix the edge strips of the mold box. Using sliding grooves to fix the edge strips provides the same position as manual gripping, but with a larger contact area, making it convenient to use. The cooperation between the sliding grooves and the edge strips of the mold box ensures a closer fit. The front and rear connecting beams enhance the overall rigidity of the frame, preventing the side beams from bending under stress during demolding and flipping, thus improving the structural stability and service life of the device. Furthermore, positioning the mold box during installation is more convenient, requiring no additional fixing components.

[0008] As a preferred embodiment of a concrete casting slab demolding device, the two ends of the front connecting beam are respectively connected to the opposite surfaces of the two side beams, and the front connecting beam blocks the front end of the chute; the two ends of the rear connecting beam are respectively connected to the top rear end surfaces of the two side beams, and the chute is open at the rear end of the side beams. This design of blocking the front end and opening the rear end of the chute clarifies the loading and unloading direction of the mold box. The front connecting beam effectively prevents the mold box from moving forward during demolding, ensuring the stability of the mold box position. It also simplifies the loading and unloading process of the mold box and improves operational efficiency.

[0009] As a preferred embodiment of a concrete casting slab demolding device, the lower end of the swing arm is hinged to the frame, and a handrail is provided between the two swing arms, with both ends of the handrail fixedly connected to the upper ends of the two swing arms respectively. The handrail allows the operator to more synchronously control the rotation direction and force of the swing arms, avoiding deformation or operational imbalance caused by excessive force on a single swing arm, thus improving the coordination and safety of the operation.

[0010] As a preferred embodiment of a concrete casting slab demolding device, the bottom surface of the two rear corners of the frame is provided with rear support legs, the height of which is the same as the height of the front support legs. In the non-demolding state, the rear support legs and the front support legs jointly support the frame, keeping the frame horizontal; before the demolding operation, the rear support legs and the front support legs jointly bear the weight of the formwork and concrete, ensuring that the device is placed stably.

[0011] As a preferred implementation of a concrete casting slab demolding device, both the lower ends of the front and rear support legs are equipped with wheels. The wheels significantly reduce the difficulty of moving the device, eliminating the need for additional handling equipment, saving manpower and time, allowing the device to flexibly adapt to the needs of different work sites, and also enabling better placement of the formwork side strips into the chute, thus improving overall construction efficiency.

[0012] As a preferred embodiment of a concrete slab demolding device, the top surface of the two front corners of the frame is provided with front columns. The front columns and the front support legs are arranged collinearly, and the front ends of the front columns and the front support legs are provided with an arc-shaped plate, the middle of which protrudes forward. When the frame flips forward to demold, the arc-shaped plate contacts the ground. As the flipping angle increases, the arc-shaped plate rolls against the ground with the protruding middle part as a fulcrum, making the flipping process smoother. When flipping back to its original position, the arc-shaped plate also assists the frame to fall back smoothly.

[0013] As a preferred embodiment of the concrete casting cover demolding device, a reinforcing rib is provided between the upper end of the front column and the frame. This improves the structural strength of the connection between the front column and the frame, prevents the front column from bending or breaking under stress, and ensures that the curved plate can stably play a buffering role.

[0014] As can be seen from the above technical solutions, the advantages of this utility model are as follows: The demolding device of this solution is convenient and quick to use and can be applied in various sites; the cooperation between the slide and the mold box edge strip makes the mold box more securely fixed, and the front and rear connecting beams enhance the overall rigidity of the frame, improving the structural stability and service life of the device. At the same time, the mold box is easy to install and position without the need for additional fasteners; the design of the slide with the front end blocked and the rear end open clarifies the loading and unloading direction of the mold box, ensuring the stability of the mold box during demolding, simplifying the loading and unloading process, and improving operating efficiency; the handrail allows the operator to control the device more synchronously. The swing arm prevents excessive stress on a single swing arm, thus avoiding deformation or operational imbalance and improving operational coordination and safety. The rear and front outriggers jointly support the frame, keeping it level when not demolded and stable under load. The wheels greatly reduce the difficulty of moving the device, saving manpower and time, allowing it to flexibly adapt to different work sites and improving overall construction efficiency. The curved plate contacts the ground when the frame is flipped, making the flipping process smoother and assisting the frame to fall back smoothly. The reinforcing ribs enhance the structural strength of the connection between the front column and the frame, preventing the front column from bending or breaking under stress and ensuring the stable function of the curved plate.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] A demolding device for cast concrete slabs includes a frame 1, which is rectangular and includes two parallel side beams 11. A front connecting beam 12 and a rear connecting beam 13 are provided between the two side beams 11. The two ends of the front connecting beam 12 are respectively connected to the opposite surfaces of the two side beams 11, and the two ends of the rear connecting beam 13 are respectively connected to the top rear end surfaces of the two side beams 11. The fixing structure of the frame 1 includes two sliding grooves 7, which are arranged on the opposite surfaces of the two side beams 11. The front connecting beam 12 blocks the front end of the sliding groove 7, and the sliding groove 7 is open at the rear end of the side beams 11. Front support legs 2 are provided on the bottom surface of the two front corners of the frame 1. Front uprights 14 are also provided on the top surface of the two front corners of the frame 1. The front uprights 14 and the front support legs 2 are arranged collinearly. The front uprights 14 and the front support legs 2 are provided with an arc-shaped plate 15 protruding forward from the middle on the front front face. A reinforcing rib 16 is provided between the upper end of the front uprights 14 and the frame 1. Lower crossbars 4 are provided on the opposite sides of the two front support legs 2. Rear support legs 9 are provided on the lower end of the front support legs 2 and the bottom surface of the two rear corners of the frame 1. The height of the rear support legs 9 is the same as the height of the front support legs 2. The lower ends of the two front support legs 2 and the two rear support legs 9 are provided with wheels 10. The frame 1 has rear columns 3 on the top surface of the two rear corners, and upper crossbars 5 are respectively provided on the opposite sides of the two rear columns 3; swing rods 6 are hinged to both sides of the frame 1, the swing rods 6 are located below the upper crossbars 5, and a handrail 8 is provided between the two swing rods 6, and the two ends of the handrail 8 are respectively fixedly connected to the upper ends of the two swing rods 6.

[0022] The procedure for using this device is as follows: First, align the edge strip of the mold box with the grooves 7 on the opposite surfaces of the two side beams 11, and push the mold box into the grooves 7 from the open portion at the rear end of the side beams 11 until the front end of the mold box contacts the front connecting beam 12 that blocks the front end of the grooves 7. The mold box is then fixed to the frame 1 via the grooves 7. At this point, the frame 1 remains horizontal under the combined support of the front support leg 2 and the rear support leg 9, and the wheels 10 can be locked as needed to ensure device stability. When demolding is required, the operator holds the handrail 8 between the two swing arms 6 and flips the swing arms 6 forward. Since the swing arms 6 are hinged to both sides of the frame 1 and located below the upper crossbar 5, during the flipping process, the swing arms 6 will push the upper crossbar 5 on the opposite side of the rear column 3 upward, causing the frame 1 to flip forward with the lower end of the front support leg 2 as the fulcrum. During this process, the arc-shaped plate 15, which is provided on the front end face of the front column 14 and the front support leg 2, will first contact the ground, and then roll into contact with the ground with the central protrusion as the flipping angle increases, assisting the frame 1 to flip smoothly. At the same time, the reinforcing rib 16 between the front column 14 and the frame 1 ensures that the front column 14 is under stable force. As the frame 1 flips over, the mold box is inverted and placed on the ground. Using the vibration generated by the flipping, the cast cover plate is poured out of the mold box, completing the demolding process. After demolding, the operator flips the swing arm 6 backward using the handrail 8. At this time, the swing arm 6 acts on the lower crossbar 4 on the opposite sides of the two front support legs 2, causing the frame 1 to return to its original position. Finally, supported by the front support legs 2 and the rear support legs 9, it returns to a horizontal state for the next operation.

[0023] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: the demolding device of this solution is convenient and efficient to operate and can adapt to simple sites; with the cooperation of the slide and the mold box edge strip, the mold box is more tightly fixed, and the front and rear connecting beams enhance the overall rigidity of the frame, which not only improves the structural stability of the device but also extends its service life. Moreover, the installation and positioning process of the mold box is simple and easy, without the need for additional fixing parts; the slide adopts a design with a closed front end and an open rear end, making the loading and unloading direction of the mold box clear and ensuring that the mold box will not shift when flipping for demolding, simplifying the loading and unloading steps and improving operational efficiency; the presence of the handrail allows the operator to more easily... The ground-adjustable control arm prevents deformation or instability of a single arm due to excessive force, enhancing operational coordination and safety. The rear and front outriggers support the frame together, keeping it level even when not demolded and stable under load. The wheels significantly reduce the difficulty of moving the device, saving manpower and time, allowing it to flexibly adapt to different work sites and improving overall construction efficiency. The curved plate contacts the ground during frame rotation, making the rotation process smoother and aiding in the frame's stable return to its original position. Reinforcing ribs increase the structural strength of the connection between the front column and the frame, preventing bending or breakage of the front column under stress and ensuring the curved plate functions stably.
