Description

Technical Field

[0001] This utility model relates to the field of rock anchor beam construction technology, and more specifically, to a rock anchor beam construction workbench. Background Technology

[0002] Rock anchor beams are a special type of underground structural component. Drilling is performed according to the design requirements at the specified location and depth. Then, anchor rods are buried, and the formwork is connected to the anchor rods. Finally, concrete is poured to form the rock anchor beam. Since one end of the anchor rod is anchored deep into the rock and the other end is connected to the beam, it effectively transfers the load borne by the beam to the surrounding rock. Due to the special nature of the site, a workbench is an essential auxiliary device.

[0003] In the existing technology, when constructing rock anchor beams, the anchor rods are relatively long and the drilling depth is also relatively deep. When anchoring the anchor rods, they are prone to tilting and cannot be kept concentric with the drill hole. Due to the high precision requirements, the one-time forming rate of rock anchor beam construction is low. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a rock anchor beam construction workbench that overcomes or at least partially solves the above technical problems.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Reference Figure 1-5This utility model provides a technical solution: a rock anchor beam construction workbench, including a support leg 1, a support plate 2 fixedly installed on the top of the support leg 1, a centering mechanism provided inside the support plate 2, the centering mechanism including a connecting cylinder 301, a toothed plate 303, a centering block 304 and a first gear 305, the connecting cylinder 301 fixedly installed inside the support plate 2, the top and bottom of the connecting cylinder 301 are open, the surface of the connecting cylinder 301 is integrally formed with a centering plate 302, and the toothed plate 304... 03 is slidably sleeved inside the centering plate 302. Several toothed plates 303 are arranged in a circular array. A centering block 304 is fixedly installed at one end of the toothed plate 303. The centering block 304 is arc-shaped. A first gear 305 is rotatably installed inside the centering plate 302, meshing with the toothed plate 303. Several limiting grooves 311 are formed inside the centering plate 302. A limiting strip 312 is fixedly installed on the top of the toothed plate 303. The limiting strip 312 is slidably sleeved inside the limiting groove 311. By setting a centering mechanism, during drilling operations, multiple first gears 305 rotate simultaneously. Through the meshing of the first gears 305 and the toothed plate 303, and the limiting action of the limiting strip 312 and the limiting groove 311, the toothed plate 303 drives the centering block 304 to move radially from the outside to the inside of the centering plate 302, continuously adjusting the position of the drill bit, thereby causing the multiple centering blocks 305 to rotate. 4. Simultaneously, center the drill rod on the drilling tool to ensure that the center of the borehole coincides with the center of the centering plate 302. Then, drill the hole. After drilling, repeat the above steps when anchoring the anchor rod to center the anchor rod so that the center of the anchor rod coincides with the center of the centering plate 302. This ensures that the center of the anchor rod coincides with the center of the borehole, preventing the anchor rod from tilting. Compared with existing technologies, this greatly improves the one-time forming rate of rock anchor beam construction and reduces construction time and cost.

[0030] Reference Figure 1-5 A connecting rod 306 is fixedly installed at the bottom of the first gear 305, and a second gear 307 is fixedly installed at the bottom of the connecting rod 306. A gear ring 308 is rotatably installed inside the centering plate 302. The gear ring 308 and the second gear 307 are meshed together. By setting the connecting rod 306 and the gear ring 308, when the gear ring 308 rotates, the meshing connection between the gear ring 308 and the second gear 307 causes the second gear 307 to rotate. Through the cooperation of the connecting rod 306, the first gear 305 is driven to rotate, thereby providing driving force for the rotation of the first gear 305.

[0031] Reference Figure 1-5A third gear 309 is rotatably mounted inside the centering plate 302. The third gear 309 meshes with the gear ring 308. A motor 310 is fixedly mounted on the bottom of the centering plate 302. The output end of the motor 310 is fixedly connected to the bottom of the third gear 309. By setting the third gear 309, the user starts the motor 310, which drives the third gear 309 to rotate. Through the meshing connection between the third gear 309 and the gear ring 308, the gear ring 308 is driven to rotate, thereby providing driving force for the rotation of the gear ring 308.

[0032] Reference Figure 1-5 A fastening plate 313 is fixedly installed on the surface of the centering plate 302. A first bolt 314 is installed on the internal thread of the fastening plate 313. The fastening plate 313 and the support plate 2 are fixedly connected by the first bolt 314. By setting the fastening plate 313 and the first bolt 314, and by the threaded connection of the first bolt 314, the fastening plate 313 and the support plate 2 are fixedly connected together, thereby providing a support effect for the centering plate 302.

[0033] Reference Figure 1-5 The support mechanism is provided inside the outrigger 1. The support mechanism includes a fixed plate 401, which is fixedly installed on the inner wall of the outrigger 1. A threaded rod 402 is rotatably installed inside the fixed plate 401. An insert rod 403 is threadedly fitted on the surface of the threaded rod 402. A limiting shell 404 is fixedly installed at the bottom of the fixed plate 401. The insert rod 403 is slidably fitted inside the limiting shell 404. A through groove 405 is provided at the bottom of the outrigger 1. Due to the harsh construction environment of the rock anchor beam, the workbench is often placed on soft soil, making it difficult for the workbench to provide a stable support effect. By setting up the support mechanism, when the threaded rod 402 rotates, the threaded connection between the threaded rod 402 and the insert rod 403, as well as the limiting effect of the limiting shell 404, causes the insert rod 403 to move downward, pass through the through groove 405, and insert into the soil. The tapered end of the insert rod 403 makes it easier to insert into the soil, thereby making the support effect of the workbench more stable.

[0034] Reference Figure 1-5 A positioning plate 406 is fixedly installed on the top of the threaded rod 402. A second bolt 407 is threaded between the positioning plate 406 and the fixing plate 401. A nut 408 is threaded onto the surface of the second bolt 407. By setting the positioning plate 406, when the insertion rod 403 is inserted to the preset depth, the positioning plate 406 is fixed by the threaded connection of the second bolt 407 and the cooperation of the nut 408, so that the threaded rod 402 cannot rotate, ensuring the stability of the insertion rod 403. When the insertion rod 403 is not needed, the cooperation of the second bolt 407 also prevents the insertion rod 403 from falling downwards due to its own weight.

[0035] Specifically, the working process or principle of this rock anchor beam construction workbench is as follows: During use, when the threaded rod 402 rotates, the threaded connection between the threaded rod 402 and the insertion rod 403, along with the limiting action of the limiting shell 404, causes the insertion rod 403 to move downwards, pass through the groove 405, and insert into the soil. When drilling, the user starts the motor 310, which drives the third gear 309 to rotate. Through the meshing connection between the third gear 309 and the gear ring 308, the gear ring 308 rotates. Through the meshing connection between the gear ring 308 and the second gear 307, the second gear 307 rotates. Through the cooperation of the connecting rod 306, the first gear 305 rotates. Through the meshing of the first gear 305 and the toothed plate 303, and the limiting action of the limiting strip 312 and the limiting groove 311, the toothed plate 303 drives the centering block 304 to move radially from the outside of the centering plate 302 to the inside of the centering plate 302, and continuously adjusts the position of the drill bit. Thus, multiple centering blocks 304 simultaneously perform centering operations on the drill rod on the drill bit, ensuring that the center of the drill hole coincides with the center of the centering plate 302. Then, drilling is performed. After drilling is completed, when anchoring the anchor rod, the above steps are repeated to center the anchor rod so that the center of the anchor rod coincides with the center of the centering plate 302, thereby making the center of the anchor rod coincide with the center of the drill hole.
