Description

Technical Field

[0001] The utility model relates to the technical field of steel cage production, in particular to a steel cage production pedestal. Background Art

[0002] At present, large-scale steel cage production equipment already exists. However, in some remote areas of China and underdeveloped countries abroad, due to the lack of equipment resources and corresponding staff, large-scale equipment is affected by transportation and personnel, and the cost of use is high. The pure manual production of steel cages is greatly affected by the experience level of workers. Therefore, it is necessary to use a steel cage production pedestal to assist manual production.

[0003] For example, the Chinese utility model patent with application number 202221454163.3 discloses a steel cage tire frame, including a base, a first tire frame card plate and a second tire frame card plate, the base is arranged on the ground, the first tire frame card plate is fixedly arranged on the base, the first tire frame card plate is provided with a plurality of first card slots for placing steel bars; the front and rear sides of the base are provided with positioning members, the base is provided with a movable slot as the positioning member moves, and a locking rod is provided through the positioning member and the movable slot; a placement slot is formed between the protruding part of the positioning member and the first tire frame card plate; the second tire frame card plate is placed in the placement slot, and the second tire frame card plate is provided with a second card slot for placing steel bars of different diameters;

[0004] For another example, the Chinese invention patent application with application number 202011460176.7 discloses a steel cage manufacturing tire frame, characterized in that it includes: a main tire frame pallet, which is vertically arranged on a base; a pallet assembly, which is provided with at least one group, the pallet assembly includes an auxiliary tire frame pallet and a fixed plate, the auxiliary tire frame pallet is flipably connected to the fixed plate, the fixed plate is vertically arranged on the base, and is arranged parallel to the main tire frame pallet; the auxiliary tire frame pallet and The upper end faces of the main tire frame pallets are all arc-shaped, and the upper end faces are provided with a plurality of U-shaped grooves for limiting the steel bars at equal intervals along the arc direction. The diameter of the arc of the upper end face of the main tire frame pallet and the diameter of the arc of the upper end face of each auxiliary tire frame pallet are all different; the connecting mechanism is configured to fix the auxiliary tire frame pallet to the main tire frame pallet when any auxiliary tire frame pallet is flipped to be in the same plane as the corresponding fixed plate, and the upper end face of the auxiliary tire frame pallet is higher than the upper end face of the main tire frame pallet.

[0005] It can be seen from the above patents and patent application documents that since the main reinforcement needs to be lifted up and away from the tire frame pallet after welding is completed, the tire frame pallet used to place the main reinforcement on the traditional production table cannot achieve 180° placement of the main reinforcement. In the process of making the steel cage, a circle of main reinforcement needs to be spot welded on the outside of the reinforcement ring. Using the traditional production table, the reinforcement ring needs to be repeatedly lifted and rotated, which not only affects work efficiency, but also increases the probability of main reinforcement position deviation, affecting the final product quality.

[0029] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0030] See also Figure 1-6 The utility model provides a technical solution: a steel cage manufacturing pedestal, comprising a base 1 and a clamping plate 2 installed on the base 1, such as Figure 1 As shown, the upper end surface of the card plate 2 is an inwardly concave arc surface for placing the main reinforcement. The card plate 2 is equipped with a plurality of convex teeth for supporting the main reinforcement and maintaining the position of the main reinforcement. The convex teeth are divided into fixed convex teeth 31 fixedly connected to the card plate 2 and movable convex teeth 32 movably connected to the card plate 2. The movable convex teeth 32 can movably enter or leave the main reinforcement rising path. When the main reinforcement needs to be placed, the movable convex teeth 32 can enter the main reinforcement rising path and place the main reinforcement normally. When the main reinforcement needs to be raised, the movable convex teeth 32 can movably leave the main reinforcement rising path so that the main reinforcement can be It can be lifted smoothly, so that the curvature of the area on the upper end surface of the card plate 2 for placing the main reinforcement can reach 180°. A half circle of main reinforcement can be placed on the upper end surface of the card plate 2 by fixing the convex teeth 31 and the movable convex teeth 32. Except for the initial loading and the final unloading, in the middle welding process, it is only necessary to lift the reinforcement ring once and turn it half a circle to weld a circle of main reinforcement on the reinforcement ring, which saves the time of lifting and rotating the reinforcement ring multiple times in the middle, improves work efficiency, and also reduces the probability of errors in the production process, thereby improving product quality.

[0031] Specifically, the convex teeth protrude from the upper end surface of the card plate 2 and are used to contact the side or bottom surface of the main rib to support the main rib, so that the main rib is arranged at intervals in the circumferential direction on the upper end surface of the card plate 2. The convex teeth are divided into fixed convex teeth 31 fixedly connected to the card plate 2 and movable convex teeth 32 movably connected to the card plate 2. The movable convex teeth 32 can move into or out of the ascending path of the main rib. Since the upper end surface of the card plate 2 is a concave arc surface, the main rib cannot be directly maintained at a specified position on the upper end surface of the card plate 2. The convex teeth protrude from the upper end surface of the card plate 2. The convex teeth contact the main rib from the side or bottom surface of the main rib to maintain the position of the main rib on the upper end surface of the card plate 2, so that the main rib is formed on the upper end surface of the card plate 2. The spatial relationship of the circumferentially spaced arrangement, and the convex teeth are divided into fixed convex teeth 31 and movable convex teeth 32. The convex teeth whose vertical projection overlaps with the main reinforcement below adopt movable convex teeth 32. The convex teeth whose vertical projection overlaps with the main reinforcement below will collide with the main reinforcement during the rising process of the main reinforcement below. Therefore, it is necessary to adopt movable convex teeth 32 to ensure that after the spot welding of the main reinforcement and the reinforcement ring is completed, all the main reinforcements can be smoothly lifted and left from the upper end surface of the clamping plate 2. Except for the start of loading and the final unloading, only one reinforcement ring needs to be lifted in the middle, which saves the time of lifting the reinforcement ring multiple times, turning it over and putting it down, shortens the production cycle, improves production efficiency, and improves production quality.

[0032] like Figure 4 As shown, the movable protruding tooth 32 is rotatably installed in the installation groove 21 opened on the upper end surface of the clamping plate 2. The radial depth of the installation groove 21 is not less than the width of the movable protruding tooth 32. The movable protruding tooth 32 can be rotated and completely hidden in the installation groove 21 to avoid the rising main ribs.

[0033] In this embodiment, the movable protruding tooth 32 is rotatably installed in the installation groove 21 opened on the upper end surface of the card plate 2. When the movable protruding tooth 32 is needed to support the main reinforcement, the movable protruding tooth 32 is protruded from the upper end surface of the card plate 2. When the main reinforcement and the reinforcement ring are spot welded and need to be lifted, the staff manually rotates the movable protruding tooth 32 into the installation groove 21. The main reinforcement can also be moved axially and the friction between the main reinforcement and the movable protruding tooth 32 can drive the movable protruding tooth 32 to rotate into the installation groove 21. After the movable protruding tooth 32 is completely hidden in the installation groove 21, it will no longer interfere with the movement of the main reinforcement, and the reinforcement ring and the main reinforcement welded on its surface can be smoothly lifted.

[0034] like Figure 1-3 As shown, the movable protruding tooth 32 is rotatably installed on the side of the clamping plate 2. The movable protruding tooth 32 enters or leaves the main reinforcement ascending path by rotating the movable protruding tooth 32. A locking block 321 is fixed to the side of the clamping plate 2 to support the movable protruding tooth 32 located on the main reinforcement ascending path.

[0035] In this embodiment, the movable protruding tooth 32 is rotatably installed on the side of the clamping plate 2, and a locking block 321 is fixedly installed on the side of the clamping plate 2. The locking block 321 contacts the bottom surface of the movable protruding tooth 32 to provide unidirectional support for the movable protruding tooth 32 from bottom to top. When the lower end surface of the movable protruding tooth 32 contacts the locking block 321, the upward side of the movable protruding tooth 32 can normally support the main reinforcement. When the main reinforcement rises, the main reinforcement located below the movable protruding tooth 32 can directly push the movable protruding tooth 32 to rotate upward and disengage from the main reinforcement rising path. At the same time, the movable protruding tooth 32 can also be pushed by hand to rotate and disengage from the main reinforcement rising path, thereby ensuring that the main reinforcement can rise normally.

[0036] Further, such as Figure 3 As shown, a reset spring 322 for resetting the movable convex tooth 32 is installed on the clamping plate 2. When the main reinforcement rises, the movable convex tooth 32 will be lifted upward. During the upward rotation of the movable convex tooth 32, the reset spring 322 will be compressed. After the subsequent main reinforcement and the movable convex tooth 32 are out of contact, the reset spring 322 will reset the movable convex tooth 32, saving the time of subsequent manual reset.

[0037] like Figure 5 As shown, the movable convex tooth 32 slides with the card plate 2 along the radial direction of the card plate 2, and the movable convex tooth 32 enters or leaves the main reinforcement ascending path by sliding the movable convex tooth 32. The card plate is provided with a support spring 324 for supporting the movable convex tooth 32, so that the movable convex tooth 32 remains on the main reinforcement ascending path. A supporting surface and an extrusion inclined surface 323 are formed on the movable convex tooth 32. The supporting surface is used to support the upper main reinforcement, and the extrusion inclined surface 323 is used to cooperate with the lower main reinforcement, so that the lower main reinforcement squeezes the extrusion inclined surface 323 during the upward movement, so as to push the movable convex tooth 32 out of the main reinforcement ascending path.

[0038] In this embodiment, the movable convex tooth 32 is slidably mounted on the side of the card plate 2, and an extrusion slope 323 is provided on the lower side of the movable convex tooth 32. When the main rib rises, it will contact the extrusion slope 323 provided on the lower side of the movable convex tooth 32, and a thrust acting on the movable convex tooth 32 in the direction away from the axis of the upper end face of the card plate 2 is generated through the extrusion slope 323. This thrust will push the movable convex tooth 32 away from the axis of the upper end face of the card plate 2. As the main rib rises, the distance that the movable convex tooth 32 is pushed also increases. The movable tooth 32 will become larger until it no longer affects the normal rise of the main rib. A support spring 324 is fixed to the end of the movable tooth 32 away from the extrusion slope 323, and the other end of the support spring 324 is fixed to the card plate 2 to keep the movable tooth 32 protruding from the upper end surface of the card plate 2. At the same time, when the movable tooth 32 is pushed by the rising main rib, the support spring 324 will be compressed, and after the main rib and the movable tooth 32 are out of contact, the support spring 324 will push the movable tooth 32 to reset.

[0039] like Figure 3As shown, all the protruding teeth face the axis of the upper end surface of the clamping plate 2.

[0040] In this embodiment, all the protruding teeth are perpendicular to the upper end surface of the clamping plate 2, and when main ribs of the same size are placed, there will be no deviation in the position of the main ribs.

[0041] like Figure 1-6 As shown, a plurality of mounting holes 4 are provided on the side of the base 1 and the side of the card plate 2. The mounting holes 4 provided on the side of the base 1 correspond to the mounting holes 4 provided on the side of the card plate 2 in a one-to-one manner. Bolts are passed through the mounting holes 4 provided on the base 1 and the card plate 2 to fix the card plate 2 on the base 1.

[0042] In the present embodiment, specifically, mounting holes 4 are provided on the surfaces of the vertical plate and the clamping plate 2, and the positions of the mounting holes 4 provided on the surfaces of the vertical plate and the clamping plate 2 correspond one to one. When the clamping plate 2 needs to be installed on the vertical plate, the mounting holes 4 provided on the surfaces of the clamping plate 2 and the vertical plate are aligned one by one. Next, bolts are passed through the mounting holes 4 and nuts are engaged on the bolts to achieve a detachable connection between the vertical plate and the clamping plate 2. When we need to make steel cages of different sizes and different main reinforcement moduli, we can only replace the clamping plate 2 on the top of the base 1. Steel cages of different sizes can be made by replacing clamping plates 2 of different sizes. The construction is convenient, the process is simple, and the investment cost is low, which improves the construction quality, speeds up the construction efficiency, saves raw materials, and saves site.

[0043] like Figure 2 As shown, a card slot 51 with an opening facing upward is provided on the base 1, and a card block 52 whose shape and size match the card slot 51 is fixedly installed on the bottom of the card plate 2. The card plate 2 and the base 1 are installed by plugging and fitting the card block 52 into the card slot 51.

[0044] In this embodiment, a card slot 51 with an upward opening is formed on the vertical plate, and a card block 52 whose shape and size match the card slot 51 is fixedly installed at the bottom of the card plate 2. The card block 52 is inserted into the card slot 51 to realize the connection between the vertical plate and the card plate 2. When working, the weight of the main reinforcement will act entirely on the card plate 2, and the stability of the connection between the card plate 2 and the vertical plate can be further increased, making the installation and disassembly of the card plate 2 and the vertical plate simpler, more convenient and more efficient.

[0045] like Figure 6 As shown, it also includes a baffle 6 for aligning the main reinforcement with the end of the main reinforcement. The baffle 6 is detachably installed on the base 1. The way in which the baffle 6 is connected to the base 1 is the same as the way in which the clamping plate 2 is connected to the base 1. When placing the main reinforcement, the baffle 6 is used to press against the end of the main reinforcement to align the main reinforcement to ensure the quality of the steel cage.

[0046] like Figure 1-6As shown, the base 1 includes a longitudinal channel steel and transverse channel steels fixed at both ends of the longitudinal channel steel. The longitudinal channel steel and the transverse channel steel are used to contact the ground. A vertical plate for connecting with the clamping plate 2 is fixedly installed on the longitudinal channel steel. Diagonal braces are also fixedly installed at both ends of the transverse channel steel. The end of the diagonal brace away from the transverse channel steel is fixedly connected to the vertical plate to support the vertical plate.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
