Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an excavation trolley capable of installing anchor bolts. Background Technology

[0002] During tunnel excavation, rock bolt support can effectively control the deformation of the surrounding rock. Currently, with the development of industrial technology, most rock bolt support construction operations in tunnels are carried out using rock bolt trolleys.

[0003] However, existing anchor bolt trolleys still require drilling operations before anchor bolt installation. After drilling, the anchor bolts are loaded onto the trolley for anchor bolt support. During the anchor bolt support process, after one anchor bolt is inserted into the borehole, the next anchor bolt needs to be manually loaded onto the trolley's boom, and the trolley needs to be controlled again to insert the anchor bolt into the borehole. This not only involves high manual labor intensity but also often requires multiple people to control the trolley to ensure accurate insertion, resulting in low construction efficiency. Therefore, a new type of excavation trolley that can install anchor bolts is needed. Summary of the Invention

Detailed Implementation

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0053] Reference Figures 1-13An excavation trolley for anchor bolt installation includes a digital anchor bolt trolley body 1. The digital anchor bolt trolley comprises a chassis system 11, a driver's cab 12, a hydraulic system 13, a drill arm 14, and a drilling-anchoring mechanism 15. The driver's cab 12 is fixedly mounted on the upper surface of the chassis system 11. The hydraulic system 13 is controlled through the driver's cab 12 and drives the drill arm 14 to work. The drill arm 14 drives the drilling-anchoring mechanism 15 to drill and install anchor bolts. The drilling-anchoring mechanism 15 is fixedly mounted at one end of the drill arm 14. The drilling-anchoring mechanism 15 consists of a load-bearing drive mechanism fixedly mounted at one end of the drill arm 14, an anchor bolt installation mechanism fixedly mounted on the surface of the load-bearing drive mechanism, and an automatic anchoring mechanism positioned above the anchor bolt installation mechanism.

[0054] The load-bearing drive mechanism includes a load-bearing drive seat 151, and a stop stroke groove 1511 with a convex inner wall is fixedly opened on the upper surface of the load-bearing drive seat 151.

[0055] The inner wall of the stop stroke groove 1511 is rotatably connected to the active drive screw 1512 and the driven drive screw 1513 via bearings. The two driven drive screws 1513 are symmetrically distributed with the axis of the active drive screw 1512 as the center.

[0056] One end of the load-bearing drive seat 151 is fixedly connected to the gearbox 1514, and one end of the active drive screw 1512 and the two driven drive screws 1513 all penetrate and extend to the inner wall of the gearbox 1514.

[0057] One end of the active drive screw 1512 is fixedly sleeved with an active gear 1515, and one end of each of the two driven drive screws 1513 is fixedly sleeved with a driven gear 1516 that meshes with the surface of the active gear 1515.

[0058] The surfaces of the driving gear 1515 and the two driven gears 1516 are slidably connected to the inner wall of the gearbox 1514.

[0059] The gear ratio of the driving gear 1515 to the driven gear 1516 is 2:1.

[0060] In use, the active drive screw 1512 drives the active gear 1515 to rotate. The active drive screw 1512 rotates 2 revolutions, which drives the driven gear 1516 to rotate 1 revolution, which in turn drives the driven drive screw 1513 to rotate 1 revolution.

[0061] The surface of the active drive screw 1512 is threaded with an active slider 1517 whose surface is adapted to slide with the inner wall of the stop stroke groove 1511. The surfaces of the two driven drive screws 1513 are threaded with driven sliders 1518 that slide with the inner wall of the stop stroke groove 1511.

[0062] In use, the active slider 1517 is located at the end of the stop stroke groove 1511 away from the gearbox 1514, and the driven slider 1518 is located at the axial position of the stop stroke groove 1511. During anchor installation, the active drive screw 1512 drives the active slider 1517 to move, and at the same time, the active gear 1515 drives the driven gear 1516 to rotate the driven drive screw 1513, which in turn drives the driven slider 1518 to move. Since the gear ratio of the active gear 1515 and the driven gear 1516 is 2:1, when the active slider 1517 moves from the end away from the gearbox 1514 to the end of the gearbox 1514, it simultaneously drives the driven slider 1518 to move the end of the gearbox 1514. When the active slider 1517 moves in the opposite direction from the end of the gearbox 1514 to the end away from the gearbox 1514, it drives the driven slider 1518 to move to the axial center of the stop stroke groove 1511.

[0063] A first reducer 1519 is fixedly installed at the other end of the load-bearing drive seat 151. A first drive motor 15110 for driving the active drive screw 1512 to rotate is fixedly installed on the surface of the first reducer 1519. The output shaft of the first drive motor 15110 is fixedly connected to the power input end of the first reducer 1519. The other end of the active drive screw 1512 is fixedly connected to the power output end of the first reducer 1519.

[0064] In use, the first drive motor 15110 drives the active drive screw 1512 to rotate through the first reducer 1519. The active drive screw 1512 drives the two driven drive screws 1513 to rotate through the active gear 1515 and the driven gear 1516.

[0065] The anchor bolt installation mechanism includes a power base 152 fixedly mounted on the upper surface of the active slider 1517, and the lower surface of the power base 152 is slidably connected to the upper surface of the load-bearing drive seat 151.

[0066] The upper surface of the power base 152 is fixedly mounted with a power motor 1521 and a power output seat 1522, and the surface of the power output seat 1522 is rotatably connected to the power shaft 1523 through a bearing.

[0067] One end of the power shaft 1523 is fixedly mounted with an electric three-jaw chuck 1524 whose surface is slidably connected to the surface of the power output seat 1522, and the other end of the power shaft 1523 is fixedly connected to the output shaft of the power motor 1521 through a coupling.

[0068] In use, the output shaft of the power motor 1521 drives the power shaft 1523 to rotate through the coupling. The power shaft 1523 drives the electric three-jaw chuck 1524 to rotate. The electric three-jaw chuck 1524 clamps and fixes the drill rod or anchor rod for drilling and anchor rod installation in the tunnel.

[0069] An electric cylinder 1525 is fixedly mounted on the surface of the power output base 1522. One end of the electric cylinder 1525 is fixedly connected to a transfer seat 1526 that is slidably connected to the upper surface of the power base 152. A transfer electric gripper 1527 is fixedly mounted on the upper surface of the transfer seat 1526. The transfer electric gripper 1527 is concentric with the electric three-jaw chuck 1524.

[0070] In use, the drill rod or anchor rod is clamped by the electric transfer jaw 1527, and then the electric cylinder 1525 drives the transfer seat 1526 and the electric transfer jaw 1527 to move, which drives the drill rod or anchor rod to move into the electric three-jaw chuck 1524. The electric three-jaw chuck 1524 clamps the drill rod or anchor rod, drives the drill rod or anchor rod to rotate, and performs drilling and anchor rod installation.

[0071] The upper surface of the driven slider 1518 and the upper surface of the load-bearing drive seat 151 are both fixedly connected to the switching control base 1528. The upper surface of the switching control base 1528 has two symmetrically distributed switching grooves 1529 with convex inner walls.

[0072] The inner walls of the two switching slides 1529 are respectively slidably connected to drill rod sliders 15210 and anchor rod sliders 15211, which are adapted to the inner walls of the switching slides 1529. The surfaces of drill rod sliders 15210 and anchor rod sliders 15211 are respectively threadedly connected to a first lead screw 15212 and a second lead screw 15213.

[0073] The surfaces of the first lead screw 15212 and the second lead screw 15213 are rotatably connected to the inner wall of the switching groove 1529 via bearings, and one end of the first lead screw 15212 and the second lead screw 15213 both penetrate and extend to the surface of the switching control base 1528.

[0074] One end of the first lead screw 15212 is fixedly sleeved with a switching drive gear 15214 that is slidably connected to the surface of the switching control base 1528, and one end of the second lead screw 15213 is fixedly sleeved with a switching synchronization gear 15215 that meshes with the surface of the switching drive gear 15214.

[0075] A switching drive motor 15216 is fixedly mounted on one end of the switching control base 1528, and the output shaft of the switching drive motor 15216 is fixedly connected to the other end of the first lead screw 15212 through a coupling.

[0076] In operation, the switching drive motor 15216 drives the first lead screw 15212 to rotate, which in turn drives the switching drive gear 15214 to rotate. The switching drive gear 15214 then drives the switching synchronization gear 15215 to rotate, which in turn drives the second lead screw 15213 to rotate. This allows the switching drive motor 15216 to simultaneously drive both the first and second lead screws 15212 and 15213 to rotate. The rotation of rod 15213 drives drill rod slider 15210 and anchor rod slider 15211 to move synchronously. During anchor rod installation, the switching drive motor 15216 drives the first lead screw 15212 and the second lead screw 15213 to rotate synchronously. This causes drill rod slider 15210 to move along the inner wall of the switching groove 1529 until it is concentric with the electric three-jaw chuck 1524. At the same time, it causes anchor rod slider 15211 to move away from one end of the switching groove 1529 and become misaligned with the electric three-jaw chuck 1524.

[0077] An electric telescopic rod 15217 is fixedly installed on the surface of the drill rod slider 15210. One end of the electric telescopic rod 15217 is fixedly connected to a limiting electromagnet 15218 with a circular surface. A limiting tube 15219 is fixedly connected to the surface of the limiting electromagnet 15218. An opening drill rod 15220 is slidably connected to the inner wall of the limiting tube 15219 and the inner wall of the limiting electromagnet 15218.

[0078] Furthermore, in actual use, it is only necessary to set a limit electromagnet 15218 on the switching control base 1528 which is fixedly connected to the surface of the load-bearing drive seat 151. Only a normal limit ring needs to be set on the driven slider 1518. By setting the limit electromagnet 15218, when the drilling rod 15220 is not working and moves to the side of the power motor 1521, the limit electromagnet 15218 is energized to attract and limit the drilling rod 15220, preventing the drilling rod 15220 from moving with the driven slider 1518 when the support anchor rod 15222 is inserted into the drill hole.

[0079] An electric clamping claw 15221 is fixedly installed on the surface of the anchor bolt slider 15211, and the surface of the electric clamping claw 15221 holds the support anchor bolt 15222.

[0080] By setting up a load-bearing drive mechanism and an anchor bolt installation mechanism, the load-bearing drive mechanism drives the anchor bolt installation mechanism to move during use. The anchor bolt installation mechanism automatically switches between the drilling rod 15220 and the support anchor bolt 15222. During anchor bolt support operations, it is not necessary to drill holes uniformly first and then adjust the trolley sequentially for anchor bolt insertion. This not only improves the efficiency of anchor bolt support operations but also reduces the difficulty of controlling the trolley during the operation, thereby achieving a more efficient and simpler anchor bolt operation.

[0081] The automatic anchoring mechanism includes fixed support plates 153 that are fixedly connected to both sides of the load-bearing drive seat 151. An anchor box 1531 with a sealing cover 1532 installed on the surface of the two fixed support plates 153 is fixedly connected to the surface of the two fixed support plates 153. The inner wall of the anchor box 1531 is V-shaped.

[0082] The surface of the sealing cover 1532 is hinged to the surface of the anchor box 1531, and the sealing cover 1532 is connected and locked to the anchor box 1531 by multiple latches.

[0083] Two symmetrically distributed pressure hydraulic cylinders 1533 are fixedly installed on the upper surface of the sealing cover 1532. The pressure hydraulic cylinder 1533 includes a pressure hydraulic rod 1534. One end of the pressure hydraulic rod 1534 passes through and extends to the inner wall of the anchor box 1531. One end of the pressure hydraulic rod 1534 is fixedly connected to a pressure strip 1535 that is slidably connected to the inner wall of the anchor box 1531.

[0084] During use, the pressure bar 1535 is driven by the pressure hydraulic rod 1534 to press and fix the support anchor rod 15222 inside the anchor box 1531. This achieves the effect of preventing the support anchor rod 15222 from flipping and misaligning inside the anchor box 1531 during the anchor support construction, thus preventing the material from being discharged and anchored.

[0085] An anchor box 1531 has an anchor release roller 1536 rotatably connected to its inner wall via a bearing. The surface of the anchor release roller 1536 is fixedly provided with multiple anchor release grooves 1537 arranged in a ring array. The surface of the anchor release roller 1536 is slidably connected to the inner wall of the anchor box 1531.

[0086] A second reducer 1538 is fixedly installed on the surface of the anchor box 1531. One end of the anchor roller 1536 passes through the anchor box 1531 and extends to the power output end of the second reducer 1538. One end of the anchor roller 1536 is fixedly connected to the power output end of the second reducer 1538.

[0087] A second drive motor 1539 is fixedly mounted on the surface of the second reducer 1538, and the output shaft of the second drive motor 1539 is fixedly connected to the power input end of the second reducer 1538.

[0088] An anchor groove 15310 extending to the lower surface of the anchor box 1531 is provided on the inner bottom wall of the anchor box 1531.

[0089] In use, the support anchor rod 15222 is placed into the anchor rod box 1531. The pressure hydraulic rod 1534 in the pressure hydraulic cylinder 1533 extends and drives the pressure bar 1535 to press and limit the support anchor rod 15222, ensuring that the support anchor rod 15222 is stacked orderly on the surface of the unloading roller 1536. The second drive motor 1539 and the second reducer 1538 drive the unloading roller 1536 to rotate, so that the support anchor rod 15222 enters the unloading groove 1537 and rotates with the unloading roller 1536. After rotating into the outlet groove 15310, it is discharged through the outlet groove 15310.

[0090] The surface of the anchor box 1531 is fixedly connected to two symmetrically distributed feeding support plates 15311. The surface of the feeding support plate 15311 is rotatably connected to the feeding shaft 15312 through bearings. The surface of the feeding shaft 15312 is fixedly installed with multiple feeding hydraulic cylinders 15313 arranged in a linear array. The feeding hydraulic cylinder 15313 includes a feeding hydraulic rod 15314.

[0091] One end of the feeding hydraulic rod 15314 is fixedly installed with a feeding electromagnet 15315 with a U-shaped surface.

[0092] A third reducer 15316 is fixedly mounted on the surface of one of the feeding support plates 15311. One end of the feeding shaft 15312 is fixedly connected to the power output end of the third reducer 15316. A third drive motor 15317 is fixedly mounted on the surface of the third reducer 15316. The output shaft of the third drive motor 15317 is fixedly connected to the power input end of the third reducer 15316.

[0093] By setting up the drilling and anchoring mechanism 15, the anchor installation mechanism is driven by the load-bearing drive mechanism during use. The anchor installation mechanism performs anchor support work, eliminating the need for multiple adjustments and controls during construction. Drilling and anchor insertion can be completed in one operation. Furthermore, the automatic anchoring mechanism automatically anchors the support anchors 15222 during construction, eliminating the need for manual anchoring one by one. This improves work efficiency and reduces the labor intensity of manual labor, thus solving the problems of high manual labor intensity and low construction efficiency in existing anchor trolley anchor support operations.

[0094] Working principle: In use, multiple support anchor rods 15222 are placed into the anchor rod box 1531, and then the sealing cover 1532 is fastened and locked to the anchor rod box 1531 by the lock. The pressure hydraulic rod 1534 in the pressure hydraulic cylinder 1533 extends and drives the pressure bar 1535 to pressure and limit the support anchor rods 15222.

[0095] During anchor bolt support operations, the drilling rod 15220 is first clamped by an electric three-jaw chuck 1524. Then, the power shaft 1523 is rotated by a power motor 1521, which in turn rotates the electric three-jaw chuck 1524 and the drilling rod 15220 to open the hole. During the opening process, the first drive motor 15110 drives the active drive screw 1512 to rotate through the first reducer 1519. The active drive screw 1512 drives the active gear 1515 to rotate. The active drive screw 1512 rotates twice, which drives the driven gear 1516 to rotate once, which drives the driven drive screw 1513 to rotate once. At the same time, it drives the active slider 1517 and the driven slider 1518 to move, which in turn drives the power base 152 to move, thus supporting the tunnel and opening the hole.

[0096] After the hole is drilled, the first drive motor 15110 and the power motor 1521 simultaneously reverse, driving the power base 152 to move in the opposite direction and reset, causing the drill rod 15220 to leave the drilled hole. Then, the first drive motor 15110 and the power motor 1521 stop working, and the electric chuck 1527 clamps the drill rod 15220. Then, the electric cylinder 1525 drives the transfer seat 1526 and the electric chuck 1527 to move, causing the drill rod 15220 to separate from the electric three-jaw chuck 1524. Then, the electric chuck 1527 releases its grip on the drill rod 15220. Then, the electric telescopic rod 15217 drives the limit electromagnet 15218 and the limit tube 15219 to move upward, causing the drill rod 15220 to separate from the electric chuck 15224. 27. Separate and simultaneously control the switching drive motor 15216 to work. The switching drive motor 15216 drives the first lead screw 15212 to rotate. The first lead screw 15212 drives the switching drive gear 15214 to rotate. The switching drive gear 15214 drives the switching synchronization gear 15215 to rotate. The switching synchronization gear 15215 drives the second lead screw 15213 to rotate. At the same time, it drives the drill rod slider 15210 and the anchor rod slider 15211 to move. The drill rod slider 15210 drives the drilling rod 15220 to move to one side of the power motor 1521. The anchor rod slider 15211 drives the clamping electric jaw 15221 to move to a position concentric with the electric three-jaw chuck 1524. Then, the automatic anchoring mechanism supports the clamping electric jaw 15221 and the material transfer electric jaw 1527 to feed the anchor rod 15222.

[0097] During loading, the second drive motor 1539 and the second reducer 1538 first drive the unloading roller 1536 to rotate, causing the support anchor rod 15222 to enter the unloading groove 1537 and rotate with the unloading roller 1536. After rotating into the outlet groove 15310, the material is discharged into the loading electromagnet 15315. The loading electromagnet 15315 is energized to attract the support anchor rod 15222. Then, the third drive motor 15317 drives the third reducer 15316 to work, which drives the loading shaft 15312 to rotate. This causes the loading hydraulic cylinder 15313 and the support anchor rod 15222 to move above the clamping electric gripper 15221 and the transferring electric gripper 1527. Then, the feeding hydraulic rod 15314 extends out of the feeding hydraulic cylinder 15313, driving the support anchor rod 15222 to move into the clamping electric gripper 15221 and the material transfer electric gripper 1527. The material transfer electric gripper 1527 and the clamping electric gripper 15221 clamp the support anchor rod 15222. Then, the feeding electromagnet 15315 is de-energized, and the feeding hydraulic rod 15314 retracts into the feeding hydraulic cylinder 15313. The third drive motor 15317 drives the third reducer 15316 to work, driving the feeding shaft 15312 to rotate. This causes the feeding hydraulic cylinder 15313 and the feeding electromagnet 15315 to move again to the lower surface of the anchor box 1531 and align with the anchor groove 15310.

[0098] Then, the support anchor rod 15222 is slightly loosened by the clamping electric jaw 15221, and the material transfer electric jaw 1527 is moved by the electric cylinder 1525 to insert one end of the support anchor rod 15222 into the electric three-jaw chuck 1524. Then, the support anchor rod 15222 is clamped by the electric three-jaw chuck 1524.

[0099] Then, the first drive motor 15110 and the first reducer 1519 drive the power base 152 and the support anchor rod 15222 to move into the borehole for anchor rod support construction.
