Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to an auxiliary construction positioning device for steel cap beams. Background Technology

[0002] A cap beam is a horizontal beam installed on top of a truss pier to support, distribute, and transfer the load of the superstructure. The main load on the cap beam is the concentrated force transmitted from its upper beam through the supports. As a bending member, the cap beam, under load, induces bending moments and shear forces at each section. Furthermore, during construction and under live loads, the cap beam also bears torque, generating torsional shear stress.

[0003] Currently, traditional cap beam manufacturing processes involve casting reinforced concrete, resulting in a heavy structure. Furthermore, on-site construction extends the construction period. Therefore, steel cap beams are gradually being adopted. Steel cap beams consist of a top plate and diaphragms. The top plate is relatively large, and multiple diaphragms are vertically welded to the same side of the top plate and then sequentially spliced ​​together. During fabrication, a crane with ropes is used to hoist the diaphragms sequentially onto the flat top plate. Initial positioning of the diaphragms is achieved with manual assistance, and finally, spot welding is used for preliminary fixation. This process results in low construction efficiency.

[0016] The clutch mechanism includes a drive gear, a drive rack, and a lifting assembly. The lifting assembly controls the meshing of the drive rack and the drive gear, so that when the drive gear moves relative to the drive rack, the drive gear can rotate, thereby driving the ball screw to rotate, thus achieving position control of the second positioning block.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] Reference Figure 1 This application discloses an auxiliary construction positioning device for steel cap beams, including a first sliding drive seat 1, a second sliding drive seat 2, and a clamping mechanism.

[0026] Reference Figure 1The first sliding drive seat 1 includes a first guide rail 11, a first sliding seat 12, and a first drive mechanism 13. The first guide rail 11 is elongated, and the first sliding seat 12 is slidably connected to the first guide rail 11. The first drive mechanism 13 drives the first sliding seat 12 to slide along the length of the first guide rail 11. The first drive mechanism 13 includes a first drive screw 131, a first drive motor 132, and two opposing first support seats 133.

The first drive motor 132 is fixed to one of the first support seats 133, and the output shaft of the first drive motor 132 is coaxially fixed with the first drive screw 131. The first drive motor 132 controls the rotation of the first drive screw 131, and the first drive screw 131 drives the first sliding seat 12 to slide along the first guide rail 11.

[0027] Reference Figure 1 The second sliding drive seat 2 has the same structure as the first sliding drive seat 1. Specifically, the second sliding drive seat 2 includes a second guide rail 21, a second sliding seat 22, and a second drive mechanism 23. The second guide rail 21 is elongated, and the first guide rail 11 and the second guide rail 21 are parallel to each other. The second sliding seat 22 is slidably connected to the second guide rail 21. The second drive mechanism 23 is used to drive the second sliding seat 22 to slide along the length direction of the second guide rail 21. The second drive mechanism 23 includes a second drive screw 231, a second drive motor 232, and two opposing second support seats 233. The second drive screw 231 is mounted above the second guide rail 21 and is rotatably connected between the two second support seats 233. The second sliding seat 22 is threadedly connected to the second drive screw 231. The second drive motor 232 is fixed on one of the second support seats 233, and the output shaft of the second drive motor 232 is coaxially fixed with the second drive screw 231. The second drive screw 231 is rotated by the second drive motor 232, and the second drive screw 231 drives the second sliding seat 22 to slide along the second guide rail 21.

[0028] Reference Figure 1 The clamping mechanism is used to pre-position the partition 200 of the steel cap beam in order to reduce the input of manpower. The first sliding drive seat 1 and the second sliding drive seat 2 are used to adjust the position of the clamping mechanism.

[0029] Reference Figure 1 , Figure 2 and Figure 3The clamping mechanism includes a first positioning plate 3, a second positioning plate 4, a first positioning block 6, and a second positioning block 7. The first positioning plate 3 and the second positioning plate 4 are parallel to each other and both span between the first sliding seat 12 and the second sliding seat 22. The first positioning plate 3 is detachably connected to the first sliding seat 12 and the second sliding seat 22. Specifically, two inserts 31 are fixed to the bottom of the first positioning plate 3. Slots 221 are provided on both the first sliding seat 12 and the second sliding seat 22. One insert 31 is inserted into the slot 221 on the first sliding seat 12, and the other insert 31 is inserted into the slot 221 on the second sliding seat 22. Thus, the first positioning plate 3 is fixed in position by means of the inserts 31.

[0030] Reference Figure 4 The bottom of the second positioning plate 4 is connected to two guide blocks. The first sliding seat 12 and the second sliding seat 22 are both provided with guide grooves 222. The two guide blocks correspond one-to-one with the two guide grooves 222, and the guide blocks are slidably set in the corresponding guide grooves 222.

[0031] Reference Figure 1 The clamping mechanism also includes a first sliding assembly 5, which includes a first sliding cylinder 51. Two sets of the first sliding cylinders 51 are arranged opposite each other. One first sliding cylinder 51 is fixed on the first sliding seat 12, and the other first sliding cylinder 51 is fixed on the second sliding seat 22. The piston rods of both first sliding cylinders 51 are fixedly connected to the second positioning plate 4. The first sliding cylinder 51 is located on the side of the second positioning plate 4 opposite to the first positioning plate 3.

[0032] The piston rod of the first sliding cylinder 51 extends and retracts, thereby driving the second positioning plate 4 to slide toward or away from the first positioning plate 3.

[0033] Reference Figure 1 , Figure 5 The first positioning block 6 and the second positioning block 7 are located between the first positioning plate 3 and the second positioning plate 4, and the first positioning plate 3, the second positioning plate 4, the first positioning block 6 and the second positioning block 7 form a receiving space for accommodating the partition plate 200 for accommodating the steel cap beam. The first positioning block 6 is fixedly connected to the first positioning plate 3 or the second positioning plate 4, and the second positioning block is slidably connected to the second positioning plate 4.

[0034] Reference Figure 1 and Figure 5The clamping mechanism also includes a second sliding assembly 8, which drives the second positioning block 7 to slide toward or away from the first positioning block 6. The second sliding assembly 8 includes a ball screw 81 and a slider 82. The ball screw 81 is rotatably connected to the second positioning plate 4 and is parallel to the second positioning plate 4. The slider 82 is slidably fitted against the second positioning plate 4 and is threadedly connected to the ball screw 81. The second positioning block 7 is fixedly connected to the slider 82. When the ball screw 81 rotates, it drives the slider 82 to slide, and the slider 82 drives the second positioning block 7 to slide.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The clamping mechanism also includes a clutch drive mechanism 9. When the second positioning plate 4 moves away from the first positioning plate 3, the clutch drive mechanism 9 is connected to the second sliding component 8 to drive the second positioning block 7 to slide away from the first positioning block 6.

[0036] Reference Figure 2 Specifically, the clutch drive mechanism 9 includes a drive gear 91, a drive rack 92, and a lifting assembly 93. The drive gear 91 is coaxially fixed to the ball screw 81, and the lifting assembly 93 is disposed on the second sliding seat 22. The lifting assembly 93 is used to drive the drive rack 92 to move vertically up and down. Reference Figure 2 The drive rack 92 is located below the drive gear 91 and is parallel to the second guide rail 21. When the drive rack 92 rises, it can mesh with the gear; when the drive rack 92 falls, it can disengage from the gear. Thus, the drive rack 92 and the drive gear 91 can switch between the meshing and disengaging states.

[0037] Reference Figure 2 The lifting assembly 93 includes a lifting cylinder 931, which is vertically arranged and fixed on the second sliding seat 22. The piston rod of the lifting cylinder 931 is fixedly connected to the bottom of the drive rack 92. To improve the stability of the lifting of the drive rack 92, multiple lifting cylinders 931 are provided. In this embodiment, there are two lifting cylinders 931.

[0038] Reference Figure 2 To avoid interference between the drive rack 92 and the second positioning plate 4, a clearance groove 41 is provided on the second positioning plate 4, and the drive rack 92 passes through the clearance groove 41.

[0039] Reference Figure 5 To improve the smoothness of the placement of the partition 200, a first guide slope 61 is provided on the side of the top of the first positioning block 6 facing the second positioning block 7, and a second guide slope 71 is provided on the side of the top of the second positioning block 7 facing the first positioning block 6.

[0040] The implementation principle of the auxiliary construction positioning device for steel cap beams in this application embodiment is as follows: A clamping mechanism composed of a first positioning plate 3, a second positioning plate 4, a first positioning block 6, and a second positioning block 7 pre-positions the partition 200 lifted by the crane, ensuring that the partition 200 accurately lands at a designated position on the top plate 100. After preliminary positioning by pre-welding the partition 200, the first sliding component 5 drives the second positioning plate 4 away from the first positioning plate 3. Simultaneously, the clutch drive mechanism 9 drives the second positioning block 7 away from the first positioning block 6 via the second sliding component 8, thereby expanding the accommodating space. Next, the worker performs secondary welding positioning on the partition 200, thus achieving stable welding of the partition 200.

[0041] When the second positioning plate 4 slides away from the first positioning plate 3, the drive gear 91 rotates due to the meshing of the drive gear 91 and the drive rack 92, which in turn drives the ball screw 81 to rotate, thereby driving the second positioning block 7 to slide.

[0042] After the worker performs secondary welding on the current partition 200, the lifting assembly 93 controls the drive rack 92 to descend, causing the drive rack 92 to separate from the drive gear 91. Then, the first sliding assembly 5 drives the second positioning plate 4 to slide towards the first positioning plate 3, causing the first positioning plate 3 and the second positioning plate 4 to clamp several welded partitions 200. During the sliding process of the second positioning plate 4 towards the first positioning plate 3, due to the separation of the drive gear 91 and the drive rack 92, the ball screw 81 will not rotate, thus keeping the second positioning block 7 relatively stationary on the second positioning plate 4.

[0043] After the first positioning plate 3 and the second positioning plate 4 clamp several welded partitions 200, the lifting assembly 93 controls the drive rack 92 to rise, so that the drive rack 92 meshes with the drive gear 91 again. This operation is repeated. After a row of partitions 200 is welded, the first drive mechanism 13 drives the first sliding seat 12 to slide, and the second drive mechanism 23 drives the second sliding seat 22 to move, moving the clamping mechanism to the next designated position, thereby achieving pre-positioning when placing partitions 200 at different positions.

[0044] The embodiments of this application improve the level of automation, reduce manpower input, and improve construction efficiency in the process of placing the partition 200.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
