Description

Technical Field

[0001] The utility model belongs to the technical field of drilling equipment, in particular to a wheel frame type slope drilling equipment. Background Art

[0002] Slope construction projects involve drilling operations. Tunnels are drilled on the slope and explosives are placed in the tunnels. The slope surface is blasted to remove floating rocks and expose the solid inner rock. At the same time, protective works such as metal protective nets are applied to the slope surface to significantly improve the safety of the slope. Especially for roadside slopes, protective construction will help improve the safety of the highway environment and avoid vehicle accidents caused by falling rocks.

[0003] Drilling equipment is usually used as equipment for drilling holes in slopes. The continuously rotating drill rod cuts the rock to form a channel. However, the following problems exist in actual construction: due to the complex surface structure and low flatness of the slope, it is not easy to set the drilling equipment at the hole position and keep it stably at the hole position during the drilling operation cycle. The solution in the existing technology is to build a supporting scaffolding or the like on the slope as a construction platform. However, the method of building a temporary construction platform leads to a significant reduction in construction efficiency. In addition, the drilling holes on the slope surface are usually designed to be in multiple places. After completing the drilling at the current position, the construction platform needs to be adjusted, such as increasing the height, before the next channel is drilled. The drilling equipment also needs to be moved, which further affects the construction efficiency. On the other hand, due to the problems of falling rocks on the slope itself, the existing method of building a construction platform and manually operating the drilling equipment on the construction platform to drill holes has great safety hazards.

[0004] In summary, it is necessary to develop and design a new type of slope drilling equipment to solve the above-mentioned technical problems. Utility Model Content

[0016] The advantages and positive effects of the present utility model are:

[0017] The present utility model provides a wheel-mounted slope drilling device. Compared with the existing method of building a construction platform in front of the slope and manually operating a drilling device on the construction platform for drilling, the drilling device in the present utility model is constructed based on a wheel-mounted trolley with the ability to self-travel. During construction, the wheel-mounted trolley abuts against the slope surface and displaces along the slope surface. The winch is used to take in and release the hanging cable to realize the lifting and displacement of the drilling device along the slope surface. By operating the stabilizing cable, the left and right displacement of the drilling device along the slope surface is realized, and after being in place, the lower end of the stabilizing cable is fixed to anchor the position of the drilling device on the slope surface. Therefore, the wheel-mounted slope drilling device of the present utility model can perform slope drilling construction without building a construction platform such as a scaffolding in front of the slope, solving the problem of low construction efficiency caused by building and adjusting the construction platform. At the same time, after the current slope hole is completed, it can be quickly and conveniently moved to the next hole position, which significantly improves the construction efficiency of slope drilling construction.

[0018] On the other hand, for this wheel-mounted slope drilling device, its power supply device, water supply device, and controller are all set on the ground in front of the slope. The ground operator controls the drilling device to perform various actions through the controller. Therefore, potential injury accidents caused by falling rocks on the slope surface during construction can be avoided by staying away from the slope. The rear wheels of the wheel-mounted trolley in the present utility model are pushed and pulled by an electric push rod. Therefore, when the drilling device is abutted against the slope surface and the drilling device and drill pipe are aligned with the drilling point on the slope surface, the angle between the drill pipe and the slope surface can be adjusted to a certain extent by the action of the electric push rod.

[0023] To further understand the inventive concept, features and effects of the present utility model, the following embodiments are given for detailed illustration.

[0024] Please refer to Figure 1 and Figure 2 , the wheel-mounted slope drilling equipment of the present utility model is constructed based on a wheel-mounted trolley. The wheel-mounted trolley includes a chassis 19 with a bracket 17 installed thereon. At the front of the chassis 19, a front wheel 20 and a travel motor 16 for driving the front wheel 20 are installed. On both sides of the rear of the chassis 19, electric push rods 3 are installed, and rear wheels 4 are installed at the end of the telescopic rods of the electric push rods 3.

[0025] Among them, the front wheel 20 and the travel motor 16 are used to drive the slope drilling equipment to travel and shift on the ground. The rear wheel 4 and the electric push rod 3 are used to control the wheel-mounted trolley to tilt at a certain angle during drilling construction to control the drilling angle. As shown in Figure 1 , the rear wheel 4 and the front wheel 20 are placed on the slope surface of the slope. When the piston rod of the electric push rod 3 extends, the drilling equipment will rotate clockwise at a certain angle. On the contrary, when the piston rod of the electric push rod 3 retracts, the drilling equipment will rotate counterclockwise at a certain angle.

[0026] In this embodiment, the bracket 17 includes a front frame, a rear frame, a top frame and a middle frame. The bottom edge of the front frame is fixedly connected to the front edge of the chassis 19, the bottom edge of the rear frame is fixedly connected to the rear edge of the chassis 19, the front edge of the top frame is fixedly connected to the top edge of the front frame, the rear edge is fixedly connected to the top edge of the rear frame, the top edge of the middle frame is fixedly connected to the middle of the top frame, and the bottom edge is fixedly connected to the middle of the chassis 19.

[0027] Furthermore, in this embodiment, the length dimension of the top frame of the support 17 is significantly smaller than the length dimension of the chassis 19, and the width dimension of the top frame of the support 17 is equal to the width dimension of the chassis 19. Therefore, the wheel-mounted trolley has a conical structure with a small top and a large bottom. The included angles between the front and rear frames of the top of the support 17 and the chassis 19 are 45° to 60°. In the structure shown in the figure, the included angles between the front and rear frames of the top of the support 17 and the chassis 19 are 60°.

[0028] A drilling device is installed in the middle of the front part of the support 17. Hoists 13 for taking in and paying out the hanging cable 22 are installed on both sides of the front part of the support 17. A stabilizing cable 5 is connected to the rear part of the support 17. There are two left and right stabilizing cables 5, and the upper ends are fixedly connected to the rear part of the top frame of the support 17. The two hoists 13 and their hanging cables 22 are used to hang the main part of the equipment during drilling construction, hang and hold the main part of the equipment at a certain height position on the slope surface of the slope. By controlling the two hoists 13 to take in and pay out the two hanging cables 22 synchronously, the height of the main part of the equipment on the slope surface of the slope can be adjusted. The stabilizing cable 5 has two functions: one function is to anchor the drilling equipment. When the main part of this drilling equipment reaches the drilling point and adjusts the drilling angle, fix the lower ends of the two stabilizing cables 5 to the anchors on the ground, such as the driven ground anchor bolts, etc. In this way, the main part of the equipment can be anchored and held on the slope surface of the slope, which can improve the stability of the drilling process; another function is that when the main part of the equipment needs to be horizontally displaced left and right on the slope surface to move to the next drilling point, the construction personnel on the ground can pull the two stabilizing cables 5 to make the main part of the drilling equipment leave the slope surface appropriately, and then pull it left or right for displacement.

[0029] The drilling device includes a frame, and the frame is detachably connected to the front frame of the support 17. A rotation drive component for driving the drill rod 24 to rotate, a precession drive component for driving the drill rod 24 to move forward, and a cooling water pipe 9 for supplying water to the drill rod 24 are installed on the frame. When the wheel-mounted trolley is in place on the slope surface of the slope and adjusts the drilling angle, it is anchored by using the stabilizing cable 5. Then, cooling water is infused into the drill rod 24 through the cooling water pipe 9. The cooling water flows out from the front end of the drill rod 24. The rotation drive component drives the drill rod 24 to rotate while the precession drive component drives the drill rod 24 to move forward, and drilling is completed on the slope surface of the slope.

[0030] In this embodiment, the frame of the drilling device includes an adapter chassis 7 detachably connected to the front frame of the bracket 17. A main support frame 23 is installed on the adapter chassis 7. A front support frame 21 is installed at the front of the main support frame 23. A rear support 27 is installed above the rear of the main support frame 23, and a front support 28 is installed above the front. A plurality of connecting rods 26 are installed between the rear support 27 and the front support 28, and each connecting rod 26 forms a cage structure.

[0031] The frame of the drilling device and the bracket 17 are assembled and connected in the following manner: Two sets of front and rear sleeves are installed on the adapter chassis 7 of the drilling device, and two sets of front and rear sleeves are installed on the front frame of the bracket 17. The adapter chassis 7 and the front frame of the bracket 17 are connected by two sets of front and rear pin shafts 29 located in the two sets of front and rear sleeves. When it is necessary to disconnect the drilling device from the wheeled trolley, the two sets of pin shafts 29 can be disassembled.

[0032] In this embodiment, the rotational drive assembly of the drilling device includes a drilling motor 12 with a hollow drive shaft located in the space between the connecting rods 26. The rear end of the drill rod 24 is threadedly connected to the front end of the drive shaft, and the front end of the cooling water pipe 9 is connected to the rear end of the drive shaft by a rotary seal. The rotary seal establishes a cooling water passage while ensuring a reliable connection between the cooling water pipe 9 and the rear end of the hollow drive shaft of the drilling motor 12. A guide rail 8 is also installed between the rear support 27 and the front support 28. A rail block that moves along the guide rail 8 is installed on the side of the casing of the drilling motor 12. By setting the guide rail 8, the drilling motor 12 can only move forward and backward and cannot rotate.

[0033] In this embodiment, the nutation drive assembly of the drilling device includes a moving seat 10. The drilling motor 12 is fixedly installed on the moving seat 10. A nutation motor 11 is also installed on the moving seat 10. A nutation gear 15 is installed on the output shaft of the nutation motor 11. A nutation rack 14 is also installed between the rear support 27 and the front support 28. The nutation gear 15 and the nutation rack 14 are engaged for transmission. During the drilling process, the nutation motor 11 drives the nutation gear 15 to rotate, and the nutation gear 15 rolls and moves along the nutation rack 14, so that the drilling motor 12 and its drill rod 24 move forward until the appropriate depth is drilled.

[0034] In this embodiment, a guiding component for the drill pipe 24 is further installed inside the front support frame 21 of the drilling device. The guiding component includes a front base 30 installed on the front support frame 21. A lead screw and a hand wheel 31 (composed of a lead screw located inside the front base 30 and a hand wheel located at the end of the lead screw) are installed on the front base 30. A moving block 32 is installed in the middle of the lead screw, and a guide 25 with a guiding hole is installed above the moving block 32. The drill pipe 24 passes through the guiding hole of the guide 25. Before construction, the drill pipe 24 is passed through the guiding hole of the guide 25, and the rear end of the drill pipe 24 is connected to the front end of the driving shaft of the drilling motor 12. By shaking the hand wheel, the moving block 32 and the guide 25 can be driven to shift left and right.

[0035] It further includes a controller 1, a power supply device 2, and a water supply device 33. The controller 1 is held by on-site construction personnel and is used to control the actions of the drilling equipment. The power supply device 2 is used to supply power to the drilling equipment, and the water supply device 33 is used to supply cooling water to the drilling equipment.

[0036] In this embodiment, a wiring terminal block 18 is installed on the middle frame of the support 17. The electric push rod 3, the traveling motor 16, the drilling motor 12, the precession motor 11, the winch 13, the controller 1, the power supply device 2, and the water supply device 33 are all connected to the wiring terminal block 18 by cables to form a complete system.

[0037] In this embodiment, the power supply device 2 is a generator set at the construction site, and the water supply device 33 is a water tank and a water pump set at the site. A waterway joint 6 is installed on the top frame of the support 17. The rear end of the cooling water pipe 9 is connected to the waterway joint 6, and the waterway joint and the outlet of the water pump are connected through a water supply pipeline.

[0038] Construction method:

[0039] Transport the wheel-mounted slope drilling equipment and its auxiliary devices to the construction site. Control the traveling and displacement of the wheel-mounted trolley on the ground through the controller 1. Before drilling construction, pass the drill pipe 24 through the guide 25 and establish a connection between the rear end and the driving shaft of the drilling motor 12. Initially, move the drilling motor 12 to the rear end. Connect the water supply device 33 to the waterway joint 6 on the equipment through a water supply pipeline.

[0040] The two hoists 13 are controlled to release the two hanging cables 22. The ends of the two hanging cables 22 are manually pulled and moved to the top of the slope and fixed to anchors set at the top of the slope, such as ground anchors. Then, the two hoists 13 are operated by the controller 1 to reel in the two hanging cables 22. The main part of the drilling equipment moves toward the slope surface. First, the front wheels 20 move to the slope surface, and then the rear wheels 4 move to the slope surface. While the hanging cables 22 are continuously reeled in, the drilling equipment rises along the slope surface until it reaches the drilling point. Then, the electric push rod 3 is controlled by the controller 1 to move, and the wheel frame trolley is adjusted clockwise or counterclockwise to a certain angle to complete the adjustment setting of the drilling angle. Then, two stabilizing cables 5 are anchored on the ground.

[0041] Then, the water pump of the water supply device 33, the drilling motor 12, and the precession motor 11 are started, and the drill rod 24 rotates steadily at a low speed while gradually precessing forward. At the same time, cooling water flows out from the front end of the drill rod 24 to achieve a cooling effect. When a sufficient depth is reached, the drill rod 24 is retracted.

[0042] Afterwards, the connection between the stabilizing cables 5 and the ground anchor is released, and the ground personnel pull the two stabilizing cables 5 to make the wheel-frame trolley leave the slope appropriately, that is, the front wheels 20 and the rear wheels 4 should be a certain distance away from the slope. The controller 1 controls the winch 13 to retract and release the hanging cables 22, and at the same time, the ground personnel cooperate by pulling the stabilizing cables 5 to transfer the drilling equipment to the next drilling point, and then anchor the two stabilizing cables 5 on the ground; repeat the above operations to carry out drilling construction at the next position.
