Description

Technical Field

[0001] This invention relates to the field of track beam construction equipment technology, and in particular to a track beam embedded part positioning device and positioning method. Background Technology

[0002] A track beam is a structure used to support railway tracks, commonly found in the construction of high-speed railways, subways, light rail, and gantry cranes. A track beam typically consists of a long, reinforced concrete main body with numerous plate-shaped embedded parts spaced along its length. During construction, formwork (usually two side formworks arranged side-by-side) is first erected at the predetermined locations on the track beam. Then, the reinforcing steel bars and embedded parts are installed within the track beam. Finally, concrete is poured into the formwork to complete the track beam construction. The embedded parts are subsequently used to connect fasteners and transfer loads; therefore, their positioning accuracy (e.g., positional deviation and levelness deviation) is crucial for the smooth operation of the track.

[0003] However, before pouring concrete, there is no connection between the embedded parts and the formwork, or between the embedded parts and the reinforcing bars. That is, the embedded parts are almost "suspended" inside the formwork, making it extremely difficult to position the embedded parts and measure their positioning accuracy. For example, one existing construction method is to place a spacer between the embedded parts and the reinforcing bars and weld the embedded parts, spacers, and reinforcing bars together. The positioning accuracy of the embedded parts can be controlled by controlling the position and size of the spacers. However, before welding the embedded parts, they are not fixed relative to the side formwork, making it difficult to measure the position and angle of the embedded parts relative to the side formwork, thus failing to guarantee the positioning accuracy of the embedded parts. After welding the embedded parts, it is impossible to readjust the position and angle of the embedded parts, often resulting in rework or even scrapping of the embedded parts after the connection is completed. Therefore, there is an urgent need to develop a positioning device for track beam embedded parts. Summary of the Invention

[0004] The purpose of this invention is to overcome the technical problem in the prior art that the embedded parts of the track beam are not connected to the template and reinforcing bars of the track beam, resulting in low positioning efficiency and insufficient positioning accuracy of the embedded parts, and to provide a positioning device and method for embedded parts of track beams.

[0005] In a first aspect, the present invention provides a positioning device for embedded parts of a track beam, comprising:

[0006] A crossbeam; the crossbeam has a first plane and a second plane respectively on two opposite sides along a first direction, the first direction being perpendicular to the length direction of the crossbeam;

[0007] The clamping device includes a vertical rod, a first jaw, a second jaw, and foot pads; the vertical rod is disposed on one side of the crossbeam along a first direction; the first jaw and the second jaw are disposed at intervals on the vertical rod, and the first jaw and the second jaw are respectively located on both sides of the crossbeam;

[0008] The foot pad is located on the side of the first claw facing the first plane. One end of the foot pad is connected to the first claw through a ball joint, and the other end of the foot pad abuts against the first plane.

[0009] At least one of the first and second jaws is movably connected to the vertical rod, causing the second jaw to move closer to or away from the second plane;

[0010] A level is connected to the first jaw, the second jaw, or a vertical rod.

[0011] When using this method to position embedded parts, the crossbeam can first be placed on the two side molds of the track beam, and the area of ​​the second plane near both ends of the crossbeam should abut against the upper surface of the side molds on both sides, so that the angle of the second plane matches the angle of the upper surface of the side molds. Then, the embedded part is placed between the second claw and the second plane, and the position of the second claw is adjusted so that the second claw approaches the second plane, until the second claw abuts and presses the embedded part against the second plane. At this time, the angle of the side of the embedded part facing the second plane, the second plane and the upper surface of the side mold are matched with each other, and the upper surface of the side mold is roughly parallel to the horizontal plane. Therefore, after the embedded part abuts and presses against the second plane, the levelness of the embedded part is initially guaranteed.

[0012] However, due to component deformation, ground conditions, and other reasons, the levelness of the upper surface of the side mold is not always within the predetermined range. Therefore, simply pressing the embedded part against the second plane cannot guarantee that the levelness of the embedded part is definitely within the predetermined range. At this time, the levelness of the embedded part can be judged by the reading of the level. If the reading of the level is within the predetermined range, the positioning of the embedded part is completed. If the reading of the level is outside the predetermined range, the clamping force (support reaction force) generated by the clamping device on the embedded part can be further changed by adjusting the distance between the first and second jaws, and the position of the clamping force acting on the embedded part can be changed by adjusting the position and angle of the clamping device relative to the embedded part (the foot pad and the second jaw abut against the first plane and the embedded part respectively, without fixed connection, so they can be dragged relative to the embedded part). Thus, the levelness of the embedded part relative to the levelness of the upper surface of the side mold can be changed.

[0013] For example, if the level instrument detects that one corner of the embedded part is raised, the entire clamping device can be dragged toward the raised part, so that the clamping force generated by the second jaw is closer to the raised part, and the distance between the first jaw and the second jaw is reduced, so that the clamping force generated by the second jaw is increased, thereby enabling the embedded part to tilt in the opposite direction until the reading of the level instrument is within the predetermined range.

[0014] During this process, the second jaw, being in direct contact with the embedded part, will change its levelness as the embedded part tilts. This, in turn, causes the levelness of the vertical rod and the first jaw to change accordingly. Therefore, the level connected to the first jaw, the second jaw, or the vertical rod will always tilt with the embedded part, accurately indicating its current levelness. The foot pad, directly contacting the first plane, is connected to the first jaw via a ball-and-socket joint. This allows the foot pad to swing relative to the first jaw, preventing it from tilting with the embedded part and ensuring its bottom surface remains in contact with the first plane to transmit load, thus guaranteeing the stability of this solution.

[0015] Regarding the positional deviation of the embedded parts, the embedded parts in this solution are pressed against the second plane of the crossbeam. Therefore, this solution can use the crossbeam as a support to adjust and measure the position of the embedded parts. Compared with the existing technology of "suspended positioning and measurement", this solution is more convenient to operate, which can improve the positioning efficiency of the embedded parts and improve the positioning accuracy of the embedded parts.

[0016] In summary, this solution can initially position the embedded parts relative to the side mold using the crossbeam, then fine-tune the positioning accuracy of the embedded parts using the clamping device, and determine the adjustment effect using a level; it can significantly improve the positioning efficiency and positioning accuracy of the track beam embedded parts.

[0017] Preferably, an adjusting screw is threaded onto the first jaw, the axis of the adjusting screw is set along the first direction, and the foot pad is connected to the adjusting screw through a ball joint.

[0018] This design adds an adjusting screw between the foot pad and the first clamping claw. This allows the design to change the clamping force of the second clamping claw on the embedded part by adjusting the distance between the first and second clamping claws, and also to change the clamping force of the second clamping claw on the embedded part by rotating the adjusting screw to change the distance between the foot pad and the first clamping claw. This gives the design more adjustment freedom, allowing operators to choose freely according to actual operating conditions.

[0019] Furthermore, the adjustment amount of the distance between the foot pad and the first chuck by the rotating screw is matched with the number of rotations of the rotating screw. Therefore, this solution can also achieve precise adjustment of the distance between the foot pad and the first chuck, which is conducive to achieving higher positioning accuracy of the embedded parts.

[0020] Preferably, the end of the adjusting screw furthest from the foot pad is connected to a handle.

[0021] This solution allows operators to rotate the adjusting screw more easily and effortlessly.

[0022] Preferably, a flexible pad layer is provided on the side of the foot pad facing the first plane.

[0023] This solution can prevent the foot pad and the first surface from scratching each other, and also prevent the foot pad from accidentally slipping relative to the first surface.

[0024] Preferably, limit stops are provided at both ends of the crossbeam, and the distance between the opposite sides of the limit stops at both ends matches the distance between the side molds of the track beam.

[0025] When using this solution, the limiting stops at both ends are respectively abutted against the inner walls of the two side molds of the track beam, which can limit the relative position of the crossbeam and the side mold and prevent the positioning of the embedded parts from deviating due to accidental movement of the crossbeam relative to the side mold.

[0026] Preferably, the number of clamping devices is at least two, the clamping devices are distributed on both sides of the crossbeam, and / or the clamping devices are spaced apart along the length of the crossbeam.

[0027] This solution can simultaneously press the embedded part onto the second plane from different positions using two or more clamping devices. This not only helps ensure the balance of the embedded part by using two or more clamping devices, thus preventing the embedded part from falling out of the clamping devices, but also further improves the control capability of the embedded part positioning accuracy through differential adjustment of different clamping devices, thereby achieving better construction quality. For example:

[0028] If the level shows that one end of the embedded part is raised while the other end is lowered, one clamping device can be placed near the raised end of the embedded part, and another clamping device can be placed near the lowered end of the embedded part. The distance between the first and second jaws of the clamping device at the lower end should be less than the corresponding distance of the clamping device at the raised end, so that the embedded part tilts in the opposite direction until the reading of the level is within the predetermined range.

[0029] Preferably, the surface of the crossbeam is powder-coated or dip-coated.

[0030] When the level of the embedded part is changed by adjusting the clamping force of the clamping device, the corresponding area of ​​the second plane of the crossbeam will undergo slight deformation due to the inclination of the embedded part. This deformation capacity determines the upper limit of the inclination angle adjustment of the embedded part. Therefore, this solution performs powder coating or injection molding on the surface of the crossbeam so that the surface of the crossbeam can generate a larger amount of deformation when under pressure, thereby increasing the upper limit of the inclination angle adjustment of the embedded part.

[0031] In a second aspect, the present invention provides a method for positioning embedded parts of a track beam, applicable to the track beam embedded part positioning device of the present invention, comprising the following steps:

[0032] S1. Place the crossbeam above the side formwork of the track beam. The length of the crossbeam is along the width of the side formwork. The area of ​​the second plane near both ends of the crossbeam abuts against the upper surface of the side formwork on both sides.

[0033] S2. Place the foot pad of the clamping device against the first plane and the embedded part against the second plane; bring the second claw close to the second plane until the second claw presses the embedded part against the second plane;

[0034] S3. Adjust the distance between the first jaw and the second jaw, and / or adjust the position and angle of the clamping device relative to the embedded part until the reading of the level is within the predetermined range.

[0035] S4. Fix the embedded parts relative to the side mold.

[0036] This solution uses a crossbeam to initially position the embedded part relative to the side mold, then uses a clamping device to fine-tune the positioning accuracy of the embedded part, and uses a level to determine the adjustment effect. After confirming that the positioning accuracy meets the requirements, the embedded part is then fixed relative to the side mold, which can significantly improve the positioning efficiency and positioning accuracy of the track beam embedded part.

[0037] Preferably, when the number of clamping devices is at least two, step S3 further includes the following steps:

[0038] The distance between the first jaw and the second jaw in each clamping device is adjusted differentially.

[0039] Preferably, after step S4, the following steps are further included:

[0040] S5. Remove the clamping device and crossbeam.

[0041] After the embedded parts are fixed relative to the side formwork in step S4, this solution removes the clamping device and the crossbeam. This not only avoids interference with the casting of the track beam by the clamping device and the crossbeam, but also facilitates the reuse of the clamping device and the crossbeam, thereby reducing the material cost of subsequent construction.

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0043] 1. This invention provides a positioning device for embedded parts of a track beam. The embedded part is pressed against the second plane of the crossbeam by a clamping device, and then the crossbeam is placed on the upper surface of the side mold, so that the embedded part can be initially positioned relative to the side mold. Moreover, the position of the clamping device relative to the crossbeam, as well as the position of the first and second claws in the clamping device, are adjustable, so that this solution can further fine-tune the position and angle of the embedded part.

[0044] In addition, this solution also includes a level, which enables operators to accurately judge the levelness of the embedded parts, thereby achieving efficient and precise positioning of the track beam embedded parts.

[0045] 2. This invention provides a positioning method for embedded parts of track beams. The embedded parts are initially positioned relative to the side mold by a crossbeam, and then the positioning accuracy of the embedded parts is finely adjusted by a clamping device. The adjustment effect is determined by a level. After confirming that the positioning accuracy meets the requirements, the embedded parts are fixed relative to the side mold. This method can significantly improve the positioning efficiency and positioning accuracy of embedded parts of track beams. Attached Figure Description

[0059] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0060] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use.

[0061] Furthermore, the use of terms such as "horizontal," "vertical," "suspension," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

Additionally, in the description of embodiments of the present invention, "several," "multiple," and "several" represent at least two. The number can be any number, including 2, 3, 4, 5, 6, 7, 8, 9, and even more than 9.

[0063] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0064] Example 1

[0065] like Figures 1 to 8 As shown, a positioning device for embedded parts of a track beam includes a crossbeam 1, a clamping device, and a level 6.

[0066] The crossbeam 1 has a first plane and a second plane on two opposite sides along a first direction, the first direction being perpendicular to the length direction of the crossbeam 1; the first plane and the second plane may have an included angle, but parallel arrangement is beneficial for simplifying the design of the clamping device, for example... Figures 1 to 2 As shown, the crossbeam 1 can be made of hollow square steel with four side planes, with its upper side plane as the first plane and its lower side plane as the second plane.

[0067] The clamping device includes a vertical rod 2, a first claw 3, a second claw 4, and a foot pad 5; the vertical rod 2 is arranged on one side of the crossbeam 1 along a first direction; the first claw 3 and the second claw 4 are spaced apart on the vertical rod 2, and the first claw 3 and the second claw 4 are respectively located on both sides of the crossbeam 1 along the first direction.

[0068] The foot pad 5 is located on the side of the first claw 3 facing the first plane. One end of the foot pad 5 is connected to the first claw 3 through a ball joint. For example, a ball socket is provided on the bottom surface of the first claw 3, and a ball head is provided on the upper end of the foot pad 5. The ball head is locked inside the ball socket. Alternatively, a ball head is provided on the bottom surface of the first claw 3, and a ball socket is provided on the upper end of the foot pad 5. The ball head is locked inside the ball socket. The other end of the foot pad 5 abuts against the first plane.

[0069] At least one of the first jaw 3 and the second jaw 4 is movably connected to the vertical rod 2. For example, one of the first jaw 3 and the second jaw 4 is movably connected to the vertical rod 2, while the other is fixed relative to the vertical rod 2. Alternatively, both the first jaw 3 and the second jaw 4 are movably connected relative to the vertical rod 2. The movable connection includes, but is not limited to, a slide rail slider mechanism, a lead screw mechanism, or a gear rack mechanism. The first jaw 3 and the second jaw 4 can move closer to or further away from each other along the first direction through the movable connection. Thus, when the first jaw 3 abuts against the first plane, the second jaw 4 can move closer to or further away from the second plane, thereby clamping the embedded part 9 between the second plane and the second jaw 4 or releasing the embedded part 9.

[0070] The level 6 is connected to the first jaw 3, the second jaw 4, or the vertical rod 2. The level 6 can be set on the side of the first jaw 3 away from the second jaw 4, so that the operator can easily observe the level 6; the level 6 can adopt existing technology, such as a bubble level, an electronic level 6, or a laser level 6.

[0071] exist Figures 5 to 8 Arrows were used to indicate directions; arrows X, Y, and Z were perpendicular to each other. Arrow X indicated the length of beam 1, arrow Z indicated the first direction, and arrow Y indicated the subsequent second direction. Figures 6 to 8 The bottom reinforcing bars of the embedded part 9 have been simplified to facilitate observation of the second claw 4.

[0072] In an optional embodiment, the dimension of the beam 1 along the second direction is smaller than the corresponding dimension of the embedded part 9, for example... Figure 6 The width of the crossbeam 1 along the direction indicated by arrow Y is smaller than the width of the embedded part 9 along the direction indicated by arrow Y. This arrangement reduces the contact area between the embedded part 9 and the crossbeam 1, making it easier for the crossbeam 1 to tilt under the clamping force of the clamping device.

[0073] In an optional embodiment, the hardness of the crossbeam 1 is less than that of the embedded part 9, so that its second plane is more likely to undergo corresponding deformation when the embedded part 9 is tilted, thereby reducing the need for the clamping force of the clamping device and avoiding damage to the embedded part 9 due to excessive clamping force.

[0074] In an optional embodiment, the surface of the crossbeam 1 is powder-coated or dip-coated.

[0075] In an optional embodiment, the surface of the beam 1 is provided with an indicator scale, which makes it easy for operators to determine the position of the embedded part 9 along the length of the beam 1.

[0076] In an optional embodiment, an adjusting screw 7 is threaded onto the first chuck 3, the axis of the adjusting screw 7 is set along the first direction, and the foot pad 5 is connected to the adjusting screw 7 through a ball joint.

[0077] In an optional embodiment, at least one of the first jaw 3 and the second jaw 4 is slidably connected to the vertical rod 2. This slidable connection can be used to quickly adjust the distance between the first jaw 3 and the foot pad 5 and the second jaw 4 connected thereto, while the adjusting screw 7 can finely adjust the distance between the foot pad 5 and the second jaw 4, thereby ensuring both the adjustment speed and the adjustment accuracy of the clamping device.

[0078] In an optional embodiment, a locking mechanism is provided between the vertical rod 2 and the first claw 3 or the second claw 4. The locking mechanism is used to lock the position of the first claw 3 or the second claw 4 relative to the vertical rod 2. Taking the locking mechanism between the first claw 3 and the vertical rod 2 as an example, the specific structure of the locking mechanism includes, but is not limited to: a plurality of limiting holes are provided at intervals on the vertical rod 2 along the length direction of the vertical rod 2, and corresponding through holes are provided on the first claw 3. The first claw 3 can move along the vertical rod 2 so that the through holes are aligned with the limiting holes at different positions. The position of the first claw 3 relative to the vertical rod 2 is locked by inserting pins into the aligned limiting holes and through holes. Alternatively, a rack is provided on one side of the vertical rod 2 along the length direction of the vertical rod 2, and a locking tooth is provided on the corresponding side of the first claw 3. The position of the first claw 3 relative to the vertical rod 2 is locked by the meshing of the locking tooth and the rack.

[0079] In an optional embodiment, the end of the adjusting screw 7 away from the foot pad 5 is connected to a handle 71.

[0080] In an optional embodiment, the side of the foot pad 5 facing the first plane is provided with a flexible pad layer, such as a silicone pad, a rubber pad, or a cork pad.

[0081] In an optional embodiment, limit stops 11 are provided at both ends of the crossbeam 1, and the distance between the opposite sides of the limit stops 11 matches the distance between the side molds 8 of the track beam. The specific structure of the limit stops 11 includes, but is not limited to, blocks, baffles, or posts, for example... Figure 1 , Figure 2 and Figure 5 As shown, triangular stiffening plates are provided at both ends of the crossbeam 1 as limit stops 11.

[0082] In optional implementations, such as Figure 2 As shown, the number of clamping devices is at least two, and the clamping devices are distributed on both sides of the crossbeam 1 along the second direction, and / or the clamping devices are distributed at intervals along the length direction of the crossbeam 1.

[0083] Example 2

[0084] A method for positioning embedded parts of a track beam, applied to a positioning device for embedded parts of a track beam in Embodiment 1, includes the following steps:

[0085] S1. Place the crossbeam 1 above the side mold 8 of the track beam, with the length of the crossbeam 1 along the width direction of the side mold 8 (i.e., Figure 5 As indicated by the arrow X, the area of ​​the second plane near both ends of the crossbeam 1 abuts against the upper surface of the side molds 8 on both sides.

[0086] And when limit stops 11 are installed at both ends of the crossbeam 1, such as Figure 5 As shown, the limiting stops 11 at both ends of the crossbeam 1 abut against the inner surfaces of the corresponding side molds 8.

[0087] S2. Place the foot pad 5 of the clamping device against the first plane, place the embedded part 9 against the second plane, and ensure that the position of the embedded part 9 along the first and second directions meets the design requirements; by adjusting the distance between the first claw 3 and the second claw 4, make the second claw 4 approach the second plane until the second claw 4 presses the embedded part 9 against the second plane.

[0088] S3. Adjust the distance between the first jaw 3 and the second jaw 4, and / or adjust the position and angle of the clamping device relative to the embedded part 9 until the reading of the level 6 is within a predetermined range, for example:

[0089] exist Figure 7 When the crossbeam 1 tilts relative to the horizontal plane (left higher than right), if only the embedded part 9 is abutted against the second plane, the embedded part 9 will also tilt along with the crossbeam 1 (left higher than right). At this time, the entire clamping device can be dragged toward the position closer to the tilted part (i.e., toward...). Figure 7 (Drag the right side of the middle) to make the clamping force generated by the second claw 4 closer to the raised part, and reduce the distance between the first claw 3 and the second claw 4, so that the clamping force generated by the second claw 4 increases, thereby enabling the crossbeam 1 to undergo slight deformation, so that the embedded part 9 can tilt α degrees relative to the crossbeam 1 until the reading of the level 6 is within the predetermined range.

[0090] It should be noted that placing the embedded part 9 against the second plane is sufficient to initially ensure the levelness of the embedded part 9. Therefore, the crossbeam 1 will only undergo minor deformation during actual operation. Figures 6 to 8 The deformation of beam 1 has been exaggerated to more intuitively illustrate its appearance and is not entirely the same as the actual situation.

[0091] S4. Fix the embedded part 9 relative to the side formwork 8. For example, place a spacer between the embedded part 9 and the longitudinal reinforcement of the track beam, and weld the embedded part 9, the spacer, and the longitudinal reinforcement of the track beam together; the spacer can be a short steel bar or metal block with the corresponding size.

[0092] In an optional implementation, when the number of clamping devices is at least two, step S3 further includes the following steps:

[0093] The distance between the first jaw 3 and the second jaw 4 in each clamping device is adjusted differentially, for example:

[0094] exist Figure 8When the crossbeam 1 tilts relative to the horizontal plane (left higher than right), if the embedded part 9 is only placed against the second plane, the embedded part 9 will also tilt along with the crossbeam 1 (left higher than right). One clamping device can be set near the raised end of the embedded part 9, and the other clamping device can be set near the lower end of the embedded part 9. The distance between the first claw 3 and the second claw 4 of the clamping device at the lower end is made smaller than the corresponding distance of the clamping device at the raised end, so that the embedded part 9 tilts in the opposite direction until the reading of the level 6 is within the predetermined range.

[0095] In an optional implementation, the following steps are included after step S4:

[0096] S5. Remove the clamping device and crossbeam 1.

[0097] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
