Description

Technical Field

[0001] This utility model relates to the technical field of steel cage production equipment, specifically to a V-shaped bar placement platform. Background Technology

[0002] In high-speed railway construction, the track is supported by concrete track slabs. The initial production of concrete track slabs involves pouring concrete into a reinforcing cage. The reinforcing cage is made of numerous reinforcing bars, including transverse bars, longitudinal bars, portal bars, vertical bars, L-shaped bars, V-shaped bars, and grounding bars. Chinese utility model patent CN217018342U discloses a reinforcing bar gripping mechanism and equipment for gripping finished V-shaped bars and placing them onto a material rack or reinforcing cage. After the V-shaped bars are placed on the material rack, a specialized gripping device transfers them from the rack to the reinforcing cage. The V-shaped bars can be positioned upright or inverted on the reinforcing cage, and these positions are alternated. The material rack accommodates and supports inverted and upright V-shaped ribs at preset intervals, allowing a specialized gripping device to pick up the arranged inverted and upright V-shaped ribs and place them into the rebar cage. The inventors discovered that when the spacing between the inverted and upright V-shaped ribs is small, and the inverted V-shaped ribs are close to the upright V-shaped ribs, the gripping equipment used to pick up the finished V-shaped ribs and place them on the material rack requires high precision. Otherwise, misalignment and interference may occur on the material rack, affecting the overall production of the rebar cage. High precision requirements for the gripping equipment also increase costs. Therefore, there is an urgent need for a V-shaped rib placement platform that ensures accurate placement of the V-shaped ribs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a V-shaped rib placement platform that ensures the accuracy of V-shaped rib placement.

[0004] To solve the above-mentioned technical problems, the utility model includes an installation part, which has an upwardly extending support part. The top of the support part has a downwardly recessed first bearing groove. The first bearing groove includes a bearing part for abutting the middle of the inverted V-shaped rib and a clearance part for avoiding the upright V-shaped rib. The bottom end of the clearance part is located below the bottom end of the bearing part. The support part is hinged to a guide frame that can swing and return to its original position. The support part has a limiting member that can limit the return position of the guide frame. The top of the guide frame has a downwardly recessed second bearing groove. The guide frame swings by first contacting the inverted V-shaped rib placed from top to bottom through the second bearing groove. The guide frame and the support part respectively engage the inverted V-shaped rib by the second bearing groove that first contacts the inverted V-shaped rib and the bearing part that contacts the inverted V-shaped rib later. The outer side of the guide frame has a guide part that can provide guidance for the upright V-shaped rib to pass through the clearance part from top to bottom after engaging the inverted V-shaped rib.

[0005] With the above structure, the mounting part is used to connect to an external frame or material rack. When placing the V-shaped rib, the inverted V-shaped rib is first placed from top to bottom. As it falls, the inverted V-shaped rib first contacts and abuts against the second bearing groove, which provides stable support. As the inverted V-shaped rib continues to fall, it drives the guide frame to swing. The guide frame guides the movement of the inverted V-shaped rib through the second bearing groove. Finally, the inverted V-shaped rib abuts against the bearing part of the first bearing groove, and the second bearing groove and the bearing part together engage the inverted V-shaped rib. Finally, the upright V-shaped ribs are placed from top to bottom. These ribs pass through the clearance section from top to bottom and are supported by the external support device. The clearance section provides clearance for the upright V-shaped ribs, and the guide section guides them as they fall. If the upright V-shaped ribs are misaligned during their descent, they can rest against the guide section and then fall from the guide section into the clearance section. Thus, the second support groove and the support section ensure the accuracy of the placement of the inverted V-shaped ribs, while the guide section and the clearance section ensure the accuracy of the placement of the upright V-shaped ribs. The support section also provides a support position for the inverted V-shaped ribs through the support section. The inverted V-shaped ribs are supported not only by the external support device but also by the support section itself, ensuring reliable support for the inverted V-shaped ribs. When the inverted V-shaped rib and the upright V-shaped rib are picked up simultaneously from bottom to top, since the bottom end of the clearance part is located below the bottom end of the bearing part, the inverted V-shaped rib detaches from the support part first, and the upright V-shaped rib detaches from the support part later. After the inverted V-shaped rib detaches from the second bearing groove and the bearing part upward, the guide frame can return to abut against the limiting member. The upright V-shaped rib can abut against the guide frame when it moves upward. The upward-moving upright V-shaped rib drives the guide frame to swing, thereby preventing the guide frame from interfering with the upward-moving upright V-shaped rib.

[0006] Furthermore, the second bearing groove has a contact surface, a transition surface, and a limiting surface connected in sequence. The contact surface is used to first contact the inverted V-shaped rib placed from top to bottom. The distance between the limiting surface and the contact surface gradually decreases from top to bottom. The distance between the guide portion and the clearance portion on the side away from the guide frame gradually decreases from top to bottom. After the inverted V-shaped rib is engaged, the minimum distance between the guide portion and the clearance portion on the side away from the guide frame is greater than the diameter of the upright V-shaped rib. By setting the contact surface, transition surface, and limiting surface, the contact surface is used to first contact the inverted V-shaped rib. The limiting surface, transition surface, and contact surface cooperate to accommodate and clamp the inverted V-shaped rib, preventing it from detaching. After the second bearing groove and the first bearing groove jointly engage the inverted V-shaped rib, the guide portion and the clearance portion cooperate to form a guide space that is wider at the top and narrower at the bottom, roughly flared, above the clearance portion, thereby providing guidance for the upright V-shaped rib to pass through the clearance portion from top to bottom.

[0007] Furthermore, the support is equipped with a torsion spring, which has two working ends. One working end of the torsion spring abuts against the guide frame, and the other working end is fixed to the support. By providing the torsion spring, the guide frame swings under the influence of gravity from the falling inverted V-shaped ribs, compressing the torsion spring. When the upward-moving upright V-shaped ribs drive the guide frame to swing through thrust, the torsion spring is also compressed. After compression, the torsion spring, through its elastic properties, drives the guide frame, which is not subject to other external forces, to rotate back to its original position until it abuts against the limiting member.

[0008] Furthermore, the support portion is provided with a third bearing groove that is spaced apart from the first bearing groove and recessed downwards. The distance between the front and rear sides of the third bearing groove gradually decreases from top to bottom, and the minimum distance between the front and rear sides of the third bearing groove is greater than the diameter of the inverted V-shaped reinforcement. By providing the third bearing groove, the support portion can also support other inverted V-shaped reinforcements, adapting to the processing and structural requirements of the rebar cage.

[0009] Furthermore, the mounting section is provided with a plurality of screw through holes at intervals. By providing screw through holes, the mounting section can be fixed to an external frame or material rack by screws passing through the screw through holes.

[0010] Furthermore, the support portion is provided with a hinge shaft, which includes a shaft body for passing through the support portion and the guide frame. The outer end of the shaft body near the guide frame is provided with an anti-detachment head with an outer diameter larger than the diameter of the shaft body. By providing the shaft body and the anti-detachment head, the shaft body is used to rotate and support the guide frame, and the anti-detachment head prevents the guide frame from detaching from the shaft body.

[0011] In summary, this utility model has the advantages of being easy to use and having a reasonable structure. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. For ease of understanding, Figure 3 The top part is the top part of this utility model. Figure 3The bottom part is the bottom part of this utility model. Figure 3 The right side is the front side of this utility model. Figure 3 The left side is the rear side of this utility model. Figure 6 , Figure 7 An inverted V-shaped rib is shown. Figure 8 , Figure 9 An upright V-shaped rib is shown.

[0026] Reference Figures 1 to 4 , Figures 10 to 12 The utility model includes a mounting part 1, which has a plurality of screw through holes 11 spaced apart. The mounting part 1 can be fixed to an external frame or material rack by screws passing through the screw through holes 11. The mounting part 1 has an upwardly extending support part 2. The mounting part 1 and the support part 2 are L-shaped as a whole and can be integrally formed by metal sheet. The top of the support part 2 has a downwardly recessed first bearing groove 21. The first bearing groove 21 includes a bearing part 211 for abutting the middle of the inverted V-shaped rib and a relief part 212 for avoiding the upright V-shaped rib. The bottom end of the relief part 212 is located below the bottom end of the bearing part 211. The bearing part 211 and the relief part 212 are connected front to back and have an upper connection. The side of the bearing part 211 closer to the relief part 212 is located below the side of the bearing part 211 away from the relief part 212. The distance between the front and back sides of the bearing part 211 gradually decreases from top to bottom. The minimum inner diameter of the supporting part 211 is larger than the diameter of the inverted V-shaped rib, and the clearance part 212 is roughly a downwardly concave elongated strip. The distance between the front and rear sides of the clearance part 212 is larger than the diameter of the upright V-shaped rib. The supporting part 211 and the clearance part 212 are connected front to back to accommodate the arrangement of inverted V-shaped ribs and upright V-shaped ribs with small spacing.

[0027] Reference Figures 1 to 5 , Figures 10 to 12The support part 2 is hinged to a guide frame 3 that can swing and return to its original position. The support part 2 is provided with a limiting member 4 that can limit the return position of the guide frame 3. The top of the guide frame 3 is provided with a downwardly recessed second bearing groove 31. The guide frame 3 swings by first contacting the inverted V-shaped rib placed from top to bottom through the second bearing groove 31. The guide frame 3 and the support part 2 are respectively engaged with the inverted V-shaped rib by the second bearing groove 31 that first contacts the inverted V-shaped rib and the bearing part 211 that contacts the inverted V-shaped rib later. Specifically, the support part 2 is provided with a hinge shaft 6. The hinge shaft 6 includes a shaft body 61 for passing through the support part 2 and the guide frame 3. The outer end of the shaft body 61 near the guide frame 3 is provided with an anti-detachment head 62 with an outer diameter larger than the diameter of the shaft body 61. The shaft body 61 is clearance-fitted with the guide frame 3, and the shaft body 61 can be interference-fitted with the support part 2 to achieve insertion. By setting a shaft 61 and an anti-detachment head 62, the shaft 61 is used to rotate the bearing guide frame 3, and the anti-detachment head 62 prevents the guide frame 3 from detaching from the shaft 61. A torsion spring 5 is installed on the support part 2. The torsion spring 5 has two working ends; one working end abuts against the guide frame 3, and the other working end is fixed to the support part 2. The limiting member 4 is cylindrical in shape. When the second bearing groove 31 requires the guide frame 3 to swing forward around the hinge axis 6 to approach the bearing part 211, one working end of the torsion spring 5 abuts against the upper part of the front side of the guide frame 3, and the limiting member 4 abuts against the lower part of the front side of the guide frame 3. By setting the torsion spring 5, the guide frame 3 swings under the influence of the gravity of the falling inverted V-shaped rib, and the torsion spring 5 is compressed; when the upward-moving upright V-shaped rib drives the guide frame 3 to swing through thrust, the torsion spring 5 is also compressed. After compression, the torsion spring 5 drives the guide frame 3, which is not subject to other external forces, to rotate back to its original position until the guide frame 3 abuts against the limiting member 4.

[0028] Reference Figures 1 to 4 , Figures 10 to 12The second bearing groove 31 has a contact surface 311, a transition surface 312, and a limiting surface 313 connected in sequence. The contact surface 311 is used to first contact the inverted V-shaped ribs placed from top to bottom, and the distance between the limiting surface 313 and the contact surface 311 gradually decreases from top to bottom. When the guide frame 3 is in its natural state, the side of the bearing part 211 near the contact surface 311 is located diagonally below the contact surface 311, so that the contact surface 311 can first contact the inverted V-shaped ribs placed from top to bottom. When the guide frame 3 is in its natural state, the limiting surface 313 is located between the front and rear sides of the clearance part 212, and the limiting surface 313 can cooperate with the bearing part 211 and the contact surface 311, increasing the bearing area for the inverted V-shaped ribs. The natural state of the guide frame 3 is when the guide frame 3 returns to its original position and abuts against the limiting member 4. The outer side of the guide frame 3 is provided with a guide portion 32, which provides guidance for the upright V-shaped rib to pass through the clearance portion 212 from top to bottom after the inverted V-shaped rib is engaged. The distance between the guide portion 32 and the side of the clearance portion 212 away from the guide frame 3 gradually decreases from top to bottom. The extension direction of the guide portion 32 is inclined in the vertical direction, and the extension direction of the guide portion 32 extends upwards at an overall angle. The guide portion 32 gradually moves away from the clearance portion 212 from bottom to top. After the inverted V-shaped rib is engaged, the minimum distance between the guide portion 32 and the side of the clearance portion 212 away from the guide frame 3 is greater than the diameter of the upright V-shaped rib. The minimum distance L1 between the outer side of the guide frame 3 below the guide portion 32 and the side of the clearance portion 212 away from the guide frame 3 is greater than the diameter of the upright V-shaped rib, so as to avoid interference between the guide portion 32 and the outer side of the guide frame 3 below the guide portion 32 and the upright V-shaped rib falling into the clearance portion 212. After the guide frame 3 engages with the inverted V-shaped rib, the guide portion 32 is located above the junction of the bearing portion 211 and the clearance portion 212. The inclined guide portion 32 can cooperate with the clearance portion 212, increasing the bearing area for the upright V-shaped rib. By providing an abutment surface 311, a transition surface 312, and a limiting surface 313, the abutment surface 311 is used to contact the inverted V-shaped rib first, and the limiting surface 313, the transition surface 312, and the abutment surface 311 cooperate to complete the accommodation and clamping of the inverted V-shaped rib, preventing the inverted V-shaped rib from detaching. After the second bearing groove 31 and the first bearing groove 21 jointly engage the inverted V-shaped rib, the guide portion 32 cooperates with the clearance portion 212 to form a guide space that is wider at the top and narrower at the bottom, roughly in the shape of a trumpet, above the clearance portion 212, thereby providing guidance for the upright V-shaped rib to pass through the clearance portion 212 from top to bottom.

[0029] Preferably, the support part 2 is provided with a third bearing groove 22 that is recessed downward and spaced apart from the first bearing groove 21. The distance between the front and rear sides of the third bearing groove 22 gradually decreases from top to bottom, and the minimum distance between the front and rear sides of the third bearing groove 22 is greater than the diameter of the inverted V-shaped reinforcement. By providing the third bearing groove 22, the support part 2 can also support other inverted V-shaped reinforcements, adapting to the processing and structural requirements of the steel cage.

[0030] In use, the mounting part 1 is used to connect to an external frame or material rack. (See reference...) Figure 10 In part a, when inserting the V-shaped ribs, the inverted V-shaped ribs are first placed from top to bottom. (Refer to...) Figure 10 In part b, the inverted V-shaped rib first contacts and abuts against the second bearing groove 31 when it falls. The second bearing groove 31 stably supports the inverted V-shaped rib. As the inverted V-shaped rib continues to fall, it drives the guide frame 3 to swing. Figure 10 The arrow in section b indicates the swing direction of the guide frame 3. When the guide frame 3 swings, the movement of the inverted V-shaped rib is guided by the second bearing groove 31. (Refer to...) Figure 10 In section c, the inverted V-shaped rib finally abuts against the bearing portion 211 of the first bearing groove 21, and the second bearing groove 31 and the bearing portion 211 together engage the inverted V-shaped rib. (Refer to...) Figure 11 The inverted V-shaped ribs are placed from top to bottom in sections d and e. These ribs pass through the clearance section 212 from top to bottom and are supported by the external support device. The clearance section 212 provides clearance for the inverted V-shaped ribs, and the guide section 32 guides the ribs as they fall. If the falling position of the inverted V-shaped rib is misaligned, it will abut against the guide section 32 and then fall from the guide section 32 into the clearance section 212. Thus, the second bearing groove 31 and the bearing section 211 ensure the accuracy of the inverted V-shaped rib placement, and the guide section 32 and the clearance section 212 ensure the accuracy of the inverted V-shaped rib placement. The support section 2 also provides a bearing position for the inverted V-shaped ribs through the bearing section 211. The inverted V-shaped ribs are supported not only by the external support device but also by the support section 2, ensuring reliable support for the inverted V-shaped ribs. When the inverted V-shaped rib and the upright V-shaped rib are picked up simultaneously from bottom to top, since the bottom end of the avoidance part 212 is located below the bottom end of the bearing part 211, the inverted V-shaped rib detaches from the support part 2 first, and the upright V-shaped rib detaches from the support part 2 later. After the inverted V-shaped rib detaches upward from the second bearing groove 211 and the bearing part 31, the guide frame 3 can return to its original position and abut against the limiting member 4. The upright V-shaped rib can abut against the guide frame 3 when it moves upward. The upward-moving upright V-shaped rib drives the guide frame 3 to swing, thereby preventing the guide frame 3 from interfering with the upward-moving upright V-shaped rib.

[0031] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims of this patent, they should all fall within the protection scope of this utility model.
