Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction technology, and more specifically, it relates to an anchor bolt trolley. Background Technology

[0002] Previously, anchor bolt installation was carried out in several separate processes. First, holes were drilled in the arch or sidewalls of the tunnel where the anchor bolts would be installed, using a rock drilling rig. After drilling, cement mortar was injected into the holes using a grouting machine. After grouting, the anchor bolts were then installed in the holes using a jacking device. Due to the multiple pieces of equipment, mutual interference, and repetitive positioning, the quality and speed of anchor bolt installation were both low, and it was also very unsafe. To change this situation, researchers and construction workers developed a fully mechanized anchor bolt trolley that can complete the three processes of drilling, grouting, and anchor bolt installation sequentially on a single machine.

[0003] During the excavation and construction of underground projects such as tunnels, underground powerhouses, and other underground engineering works, geological hazards such as water inrush, gas explosions, rock bursts, and large deformations are prone to occur due to the structural properties of the rock mass, groundwater, harmful gases such as methane, and geological conditions such as ground stress. These hazards seriously threaten the personal safety of construction workers and affect the safe and smooth progress of construction operations. Currently, drilling and modern geophysical exploration methods are generally used to conduct exploration and analysis before or during construction to understand the engineering geological and hydrogeological conditions ahead of the excavation work area in advance, thereby guiding the engineering construction.

[0004] In addition, during the anchor drilling operation on the anchor trolley, there may be safety hazards such as large materials or gravel falling and roof collapse. Therefore, temporary support needs to be set up on the anchor trolley to ensure the safety of the operators.

[0005] However, existing anchor bolt trolleys have problems such as complex structure, heavy weight, large size, and large space occupation. They cannot integrate geophysical exploration and temporary support into a single anchor bolt trolley. The construction steps are complicated, the operation is very inconvenient, and the work efficiency is low. Utility Model Content

[0006] To address the problems of existing anchor bolt trolleys being complex in structure, heavy in weight, large in size, and occupying a lot of space, making it impossible to integrate geophysical exploration and temporary support into a single anchor bolt trolley, resulting in complex construction steps, inconvenient operation, and low work efficiency, the purpose of this utility model is to provide an anchor bolt trolley. The anchor bolt trolley includes: a vehicle body, an installation platform mounted on the vehicle body, an anchor bolt drilling rig, a geophysical drilling rig, and temporary support; the anchor bolt drilling rig is adjustablely mounted on the installation platform via its drill arm, and the temporary support is rotatably mounted on the installation platform; the geophysical drilling rig is slidably mounted on the temporary support.

[0007] Furthermore, the temporary support includes a support top for placing the support net and a telescopic arm capable of adjusting the support height; wherein, one end of the telescopic arm is hinged to the installation platform, and the other end of the telescopic arm is connected to the support top.

[0008] Furthermore, the geophysical drilling rig is equipped with a mounting base at its bottom, and a slide is provided on the telescopic arm, allowing the mounting base to slide on the slide.

[0009] Furthermore, the telescopic arm includes an outer arm and an inner arm, the outer arm being slidably fitted onto the inner arm to achieve length adjustment of the telescopic arm; wherein, the slide is a guide rail disposed on the side of the outer arm near the geophysical drilling rig, and two L-shaped sliders are disposed opposite each other on the side of the mounting base near the telescopic arm, the guide rail being sandwiched between the two L-shaped sliders.

[0010] Furthermore, the geophysical drilling rig includes a geophysical drill rod and a drill rod drive unit; the geophysical drill rod is disposed at the power output end of the drill rod drive unit, and the drill rod drive unit is capable of driving the geophysical drill rod to rotate; wherein, the drill rod drive unit is slidably disposed on the temporary support via the mounting base.

[0011] Furthermore, the geophysical drilling rig also includes a drill rod clamping part, which is located at the front end of the temporary support and is used for clamping, installing, and removing the drill rod.

[0012] Furthermore, the drill pipe clamping part includes a first clamping assembly, which is openably mounted on the temporary support and has an openable first drill pipe hole.

[0013] Furthermore, the drill pipe clamping part also includes a first clamping cylinder that drives the first clamping assembly to open or close the first drill pipe hole.

[0014] Furthermore, the drill rod clamping part also includes a second clamping assembly, which can drive the geophysical drill rod to rotate within the first drill rod hole, so as to remove the geophysical drill rod from the power output end of the drill rod drive part.

[0015] Furthermore, the drill pipe clamping part also includes a second clamping cylinder that drives the connection to the second clamping assembly.

[0016] Furthermore, the mounting platform is vertically and flexibly mounted on the vehicle body.

[0017] Furthermore, the anchor bolt trolley also includes a lifting cylinder and a four-link rod disposed between the installation platform and the vehicle body; the lifting cylinder can drive the installation platform to rise and fall relative to the vehicle body through the four-link rod.

[0018] Furthermore, the vehicle body includes a body section and a running section disposed below the body section; wherein the running section is a tracked running section.

[0019] Furthermore, the anchor bolt trolley also includes a hydraulic drive system; the hydraulic drive system is mounted on the trolley body and provides driving force for the entire vehicle.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] 1. By setting the temporary support to be hinged to the installation platform and placing the geophysical drilling rig on the temporary support, the temporary support can be flipped down during the operation of the geophysical drilling rig and used as the mechanical arm of the geophysical drilling rig. The geophysical drilling rig can slide on the temporary support to adjust the position of the geophysical anchor bolts. There is no need to set up a separate mechanical arm or other components for support and position adjustment for the geophysical drilling rig. The geophysical drilling rig can be directly supported by the existing temporary support, which simplifies the structure of the anchor bolt trolley and solves the problems of the existing geophysical drilling rig's anchor bolt trolley being heavy, large, and having complicated construction steps, making it very inconvenient to operate, thus improving the work efficiency.

[0022] 2. Since the anchor drilling rig, geophysical drilling rig, and temporary support are all mounted on the installation platform rather than directly on the vehicle body, the positions of these components can be synchronously adjusted by changing the position of the installation platform. This allows for modular installation and position adjustment of the anchor drilling rig, geophysical drilling rig, and temporary support. By setting the installation platform as a lifting platform, it can supplement the height of the temporary support during support operations, geophysical drilling operations, and anchor drilling operations, increasing the working range of the anchor drilling rig and geophysical drilling rig, and increasing the support height of the temporary support.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0034] Combination Figures 1 to 8 The anchor bolt trolley includes, for example, a vehicle body, an installation platform 30 mounted on the vehicle body, an anchor bolt drilling rig 61, a geophysical drilling rig 50, and a temporary support 40. The geophysical drilling rig 50 is mounted on the temporary support 40 and can slide on the temporary support 40, enabling the advancement of one drill rod during operation to detect gas and water.

[0035] The temporary support 40 and the anchor drilling rig 61 are mounted on the vehicle body via the mounting platform 30. When the temporary support 40 is in operation, it is located at the front end of the vehicle body and can extend upwards to support the roof, preventing roof collapse or material / rockfall during the operation of the anchor drilling rig 61, thus ensuring the safety of the workers. When the geophysical drilling rig 50 is conducting geological exploration operations such as gas and water exploration, the temporary support 40 can be flipped down, acting as the mechanical arm of the geophysical drilling rig 50, allowing the geophysical drilling rig 50 to slide forward relative to the mounting platform 30 on the vehicle body, advancing the geophysical drill rod 52.

[0036] The anchor bolt drilling rig 61 is adjustablely mounted on the installation platform 30 via the drill arm 62. For example, this anchor bolt trolley is a three-arm anchor bolt trolley. The geophysical drilling rig 50 is rotatably mounted at the front end of the installation platform 30 via a temporary support 40, and the two anchor bolt drilling rigs 61 are adjustablely mounted on both sides of the installation platform 30 via the drill arm 62. The temporary support 40 is hinged to the installation platform 30, and the hydraulic drive system 70 of the anchor bolt trolley can drive the temporary support 40 to rotate 90 degrees up and down relative to the installation platform 30 via hydraulic cylinders. It can be understood that since the anchor bolt drilling rig 61, geophysical drilling rig 50, and temporary support 40 are all mounted on the installation platform 30 rather than directly on the vehicle body, the positions of the anchor bolt drilling rig 61, geophysical drilling rig 50, and temporary support 40 can be synchronously adjusted by adjusting the position of the installation platform 30, thereby achieving modular installation and position adjustment of the anchor bolt drilling rig 61, geophysical drilling rig 50, and temporary support 40.

[0037] Understandably, by setting the temporary support 40 to be hinged to the installation platform 30 and placing the geophysical drilling rig 50 on the temporary support 40, the temporary support 40 can be flipped down and used as the robotic arm of the geophysical drilling rig 50 during operation. The geophysical drilling rig 50 can slide on the temporary support 40 to adjust the position of the geophysical anchor bolts. There is no need to set up a separate robotic arm or other components for support and position adjustment for the geophysical drilling rig 50. The geophysical drilling rig 50 can be directly supported by the existing temporary support 40, which simplifies the structure of the anchor bolt trolley and solves the problems of the existing geophysical drilling rig 50's anchor bolt trolley being heavy, large, and having complicated construction steps, making it very inconvenient to operate, thus improving work efficiency.

[0038] Furthermore, the temporary support 40 includes a support top 41 for placing the support net and a telescopic arm 42 that can adjust the support height. One end of the telescopic arm 42 is hinged to the installation platform 30, allowing the temporary support 40 to rotate relative to the installation platform 30 around the hinge axis, thereby driving the geophysical drilling rig 50 mounted on the temporary support 40 to rotate together, flipping 90 degrees downward from above the installation platform 30 to the front of the installation platform 30. The other end of the telescopic arm 42 is connected to the support top 41. When the temporary support 40 flips 90 degrees downward from above the installation platform 30 to the working position of the geophysical drilling rig 50 in front of the installation platform 30, the support top 41 serves as the front support of the telescopic arm 42, supporting the front end of the telescopic arm 42. This prevents insufficient support at the front end of the temporary support 40 from affecting the operational stability of the geophysical drilling rig 50 when it slides forward on the temporary support 40 for propulsion operations.

[0039] For example, the support top 41 is H-shaped, formed by a horizontal bar and two vertical bars connected together. The support top 41 is connected to the telescopic boom 42 via the horizontal bar. During temporary support 40 operations, the support netting is placed on the H-shaped support top 41, with its four corners fixed to the two vertical bars. The horizontal bar provides support and transmits power. The telescopic boom 42 extends and retracts, raising and lowering the support top 41 vertically via the horizontal bar, adjusting the height of the temporary support 40. This ensures that the support netting on the support top 41 supports the roof slab above, providing support and preventing roof collapse accidents, falling debris, or falling materials that could injure people, thus ensuring the safety of construction workers.

[0040] When the geophysical drilling rig 50 is performing geophysical exploration operations, the temporary support 40 rotates 90 degrees downwards from its working position above the installation platform 30 to its working position in front of the installation platform 30. At this time, the two vertical rods of the H-shaped support top 41 serve as front-end supports for the telescopic boom 42, providing support to the front end of the telescopic boom 42 and enabling the geophysical drilling rig 50 to advance smoothly. The end face of the support top 41 where the support net is placed rests against the side wall of the tunnel or other construction site, further improving the operational stability of the geophysical drilling rig 50. In one specific embodiment, the end face of the support top 41 where the support net is placed is also provided with a protrusion. For the uneven side wall of the tunnel or other construction site, this protrusion can be embedded in the uneven area to ensure the stability of the front end of the temporary support 40. When the geophysical exploration work of the geophysical drilling rig 50 is completed, the hydraulic cylinder can drive the temporary support 40 to rotate upward 90 degrees, retract the temporary support 40, and reset the temporary support 40 from the working position of the geophysical drilling rig 50 to the working position of the temporary support 40.

[0041] For example, the installation platform 30 has a hinge seat at its front end, through which the telescopic arm 42 can be rotatably mounted. For example, the hinge seat is provided with a positioning element that can mechanically position the rotation angle of the temporary support 40. When the temporary support 40 is rotated into position, the positioning element can prevent the temporary support 40 from rotating further.

[0042] The hinge seat can be located on the upper surface, lower surface, or side of the mounting platform 30; there are no restrictions on this. Preferably, the hinge seat is located at the front of the lower surface of the mounting platform 30 and extends beyond the front end of the mounting platform 30. It is understood that, compared to placing the hinge seat on the upper surface of the mounting platform 30, placing it on the lower surface allows the geophysical drilling rig 50 to operate at a lower minimum height, increasing its operating area and expanding its scope for geological exploration such as water and gas detection.

[0043] Furthermore, the geophysical drilling rig 50 is equipped with a mounting base 51 at its bottom, and a slide is provided on the telescopic arm 42, on which the mounting base 51 can slide. It is understood that by providing the mounting base 51 at the bottom of the geophysical drilling rig 50 and the slide cooperating with the mounting base 51 on the telescopic arm 42, the geophysical drilling rig 50 can slide forward on the telescopic arm 42 along the extension direction of the slide, thus guiding and limiting the sliding of the geophysical drilling rig 50.

[0044] Furthermore, the telescopic boom 42 includes an outer boom 421 and an inner boom 422. The outer boom 421 is slidably fitted onto the inner boom 422 to achieve length adjustment of the telescopic boom 42. This length adjustment allows for adjustment of the support height of the temporary support 40 and the advance distance of the geophysical drilling rig 50. The slide is a guide rail 43 located on the side of the outer boom 421 near the geophysical drilling rig 50. Two L-shaped sliders 511 are positioned opposite each other on the mounting base 51 near the telescopic boom 42, with the guide rail 43 sandwiched between the two L-shaped sliders 511. In one specific embodiment, the width of the slide is greater than the width of the outer boom 421, and the slide is positioned above the outer boom 421, sandwiched between the two L-shaped sliders 511.

[0045] Furthermore, the geophysical drilling rig 50 includes, for example, a geophysical drill rod 52 and a drill rod drive unit 53. The geophysical drill rod 52 is located at the power output end of the drill rod drive unit 53, which is the power source for the drill bit of the geophysical drill rod 52. The drill rod drive unit 53 can drive the geophysical drill rod 52 to rotate forward or backward. The drill rod drive unit 53 is slidably mounted on the temporary support 40 via a mounting base 51. For example, the drill rod drive unit 53 is a drill box, which is mounted on the mounting base 51, and the geophysical drill rod 52 is mounted on the power output end of the drill box. The geophysical drill rod 52 is advanced forward by the drill box sliding on a carriage. The power output end of the drill box is equipped with a drill sleeve, which can accommodate geophysical drill rods 52 of different specifications and models. This means that the geophysical drilling rig 50 can replace geophysical drill rods 52 with different signals according to different construction needs, making it more versatile than a geophysical drilling rig 50 that can only install one type of geophysical drill rod 52.

[0046] Furthermore, the geophysical drilling rig 50 also includes a drill rod clamping part 54, which is located at the front end of the temporary support 40 and is used for clamping, installing, and removing the geophysical drill rod 52. For example, the drill rod clamping part 54 is fixedly installed on the temporary support 40. When the temporary support 40 is rotated 90 degrees downward from above the installation platform 30 to the working position of the geophysical drilling rig 50 in front of the installation platform 30, the drill rod clamping part 54 is just against the construction side wall to clamp and orient the geophysical drill rod 52.

[0047] Furthermore, the drill pipe clamping part 54 includes a first clamping assembly 541, which is foldably mounted on the temporary support 40 and has an openable first drill pipe hole 543. For example, the first clamping assembly 541 includes two first clamping members, each of which is matched with a first clamping cylinder 544. When the geophysical drill pipe 52 is being operated, the first drill pipe hole 543 is in a closed state, and the drill box can drive the geophysical drill pipe 52 to rotate within the first drill pipe hole 543. When the geophysical drill pipe 52 needs to be removed or replaced, the first clamping cylinder 544 drives the two first clamping members to move away from each other, opening the first drill pipe hole 543; after the geophysical drill pipe 52 is removed or replaced, the first clamping cylinder 544 drives the two first clamping members to move closer to each other, closing the first drill pipe hole 543. By setting an openable first drill pipe hole 543, it is easier to install and remove the geophysical drill pipe 52 from the first drill pipe hole 543 of the drill pipe clamping part 54. By equipping the first clamping assembly 541 with a first clamping cylinder 544, the first clamping assembly 541 can be automatically controlled, and the first drill pipe hole 543 can be automatically opened and closed through the electronic control system.

[0048] Furthermore, the drill pipe clamping part 54 also includes a second clamping assembly 542, which can rotate the geophysical exploration drill pipe 52 within the first drill pipe hole 543 to detach the geophysical exploration drill pipe 52 from the power output end of the drill pipe drive part 53. For example, the drill pipe clamping part 54 also includes a second clamping cylinder 545 that drives the second clamping assembly 542. Two second clamping cylinders 545 are symmetrically arranged on both sides of the second clamping assembly 542. The second clamping cylinders 545 can rotate the geophysical exploration drill pipe 52 within the first drill pipe hole 543, thereby detaching the geophysical exploration drill pipe 52 from the power output end of the drill pipe drive part 53, or installing the geophysical exploration drill pipe 52 at the power output end of the drill pipe drive part 53.

[0049] In one specific embodiment, when the second clamping cylinder 545 rotates the geophysical probe drill rod 52 in reverse within the first drill rod hole 543, the geophysical probe drill rod 52 can be detached from the power output end of the drill rod drive unit 53. Then, the first clamping cylinder 544 drives the two first clamping members to move away from each other, opening the first drill rod hole 543, and then the geophysical probe drill rod 52 is taken out. After replacing the geophysical probe drill rod 52 with a different model, the first drill rod hole 543 is closed, and the second clamping cylinder 545 rotates the geophysical probe drill rod 52 in the first drill rod hole 543 to install the replaced geophysical probe drill rod 52 into the power output end of the drill rod drive unit 53.

[0050] Preferably, the installation platform 30 is flexibly mounted on the vehicle body via the lifting drive unit 20. The lifting drive unit 20 can drive the installation platform 30 to move horizontally or extend forward, supplementing the lifting height of the anchor drilling rig 61, the geophysical drilling rig 50, and the temporary support 40, and supplementing the forward extension distance of the anchor drilling rig 61, the geophysical drilling rig 50, and the temporary support 40, thereby further expanding the working range of the anchor drilling rig 61, the geophysical drilling rig 50, and the temporary support 40.

[0051] For example, the lifting drive unit 20 consists of a lifting cylinder and a four-bar linkage disposed between the mounting platform 30 and the vehicle body; the lifting cylinder is used to provide driving force to drive the mounting platform 30 to move, and the four-bar linkage is used to ensure that the mounting platform 30 always remains horizontal during movement.

[0052] Furthermore, the vehicle body includes a body section 11 and a running gear 12 disposed below the body section 11. For example, the body section 11 is the vehicle body, and the running gear 12 is the wheel. Preferably, the running gear 12 is a tracked running gear 12, which provides better shock absorption and walking stability in harsh construction environments, preventing excessively bumpy rides.

[0053] Furthermore, the anchor bolt trolley also includes a hydraulic drive system 70 and an electronic control system; the hydraulic drive system 70 and the electronic control system are located at the rear end of the trolley body, providing driving force and electronic control support for the entire vehicle. For example, the hydraulic drive system 70 and the electronic control system are located behind the liftable installation platform 30, and a cable drum 80 for winding and unwinding cables is also provided on one side of the electronic control system to avoid inconvenience caused by cable tangling.

[0055] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.
