Description

Technical Field

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

[0002] Coal mine anchor bolt trolleys have become core equipment for modern mine roadway support by replacing manual labor with mechanization, ensuring construction quality with intelligence, and improving safety levels with structure.

[0003] However, existing anchor bolt trolleys typically have multiple drill arms mounted on the main body via separate swivel seats, resulting in a large lateral width that hinders operation in narrow tunnels. Furthermore, the hydraulic cylinders that drive the trolley's left-right swing are either directly exposed on the outside of the drill arms, making them susceptible to damage from external impacts and disrupting the drilling process. Alternatively, if the cylinders are mounted directly on the main body, operators must adjust the drill arms of each trolley individually to control the simultaneous height adjustment of multiple anchor bolt rigs, making the process cumbersome. Utility Model Content

[0004] To address the technical problem that the drive cylinders of existing anchor bolt trolleys are directly exposed on the outside of the drill arm, making them susceptible to damage from external collisions and affecting the normal construction progress of the anchor bolt drilling rig, the purpose of this utility model is to provide an anchor bolt trolley. The anchor bolt trolley includes: a vehicle body with a lifting platform; an anchor bolt drilling rig, adjustablely mounted on the lifting platform by means of the drill arm position; a T-shaped boom mounting base located on the rear side of the lifting platform, with the rear end of the drill arm rotatably mounted at the left and right ends of the T-shaped boom mounting base; and boom slewing cylinders located on the inner side of the drill arm for driving the drill arm to swing left and right on the T-shaped boom mounting base. The two boom slewing cylinders are located within two L-shaped recessed areas of the T-shaped boom mounting base.

[0005] Furthermore, the T-shaped boom mounting base includes: a mounting frame, arranged along the width direction of the lifting platform, and equipped with a first rotary cylinder hinge seat; one end of the boom rotary cylinder is hinged to the first rotary cylinder hinge seat, and the other end is hinged to a second rotary cylinder hinge seat on the inner side of the drill arm; a T-shaped mounting cover plate is arranged above the mounting frame, forming L-shaped concave areas on both sides; wherein, when the boom rotary cylinder drives the drill arm to swing left and right, the boom rotary cylinder is always located within the L-shaped concave area.

[0006] Furthermore, the T-shaped boom mounting base also includes: a boom hinge shaft, which is disposed on the T-shaped mounting cover plate, and the drill arm is rotatably mounted on the T-shaped boom mounting base via the boom hinge shaft; wherein, two boom hinge shafts are symmetrically distributed at the left and right ends of the T-shaped mounting cover plate.

[0007] Furthermore, the anchor bolt trolley also includes a boom lifting cylinder, which is located below the drill arm.

[0008] Furthermore, the anchor bolt trolley also includes a lifting mechanism, which is disposed between the lifting platform and the trolley body.

[0009] Furthermore, the lifting mechanism includes: a lifting cylinder assembly and a four-bar linkage; the lifting cylinder assembly is mounted on the vehicle body and drives the lifting platform, and the four-bar linkage is located between the vehicle body and the lifting platform.

[0010] Furthermore, the lifting cylinder assembly includes one front lifting cylinder and two rear lifting cylinders arranged in a triangle on the vehicle body.

[0011] Furthermore, the lifting mechanism also includes auxiliary connecting rods, which are disposed on both sides of the front lifting cylinder.

[0012] Furthermore, the anchor bolt trolley also includes a temporary support structure, which is rotatably mounted at the front end of the lifting platform; wherein a geophysical drilling rig is mounted on the temporary support.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The boom slewing cylinder is located on the inside of the drill arm, preventing damage from external impacts and ensuring the normal operation of the anchor drilling rig. By arranging the boom mounting base in a T-shape, the two boom slewing cylinders located on the inside of the drill arm can be placed within the two L-shaped recessed areas of the T-shaped boom mounting base. This better protects the boom slewing cylinders and allows for a more compact arrangement of the two drill arms and a smaller anchor drilling rig, making it suitable for narrow tunnel working environments.

[0015] 2. Because the drill arms of the anchor bolt drilling rig are mounted on the lifting platform, rather than directly on the vehicle body, construction personnel can achieve synchronous height adjustment of the two anchor bolt drilling rigs by adjusting the position of the lifting platform. This eliminates the need to adjust the two drill arms separately, making the operation simpler, faster, and more efficient. Attached Figure Description

[0026] 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.

[0027] Combination Figures 1 to 8 The anchor bolt trolley includes, for example, a vehicle body 10, a lifting mechanism 20, a lifting platform 30, a T-shaped boom mounting base, a boom rotation cylinder 51, a drill arm 61, and two anchor bolt drilling rigs 62. The lifting platform 30 is mounted on the vehicle body 10 via the lifting mechanism 20; the two anchor bolt drilling rigs 62 are mounted on the lifting platform 30 via two drill arms 61, which can be raised, lowered, and swung left and right. Construction personnel can control the lifting platform 30 to raise and lower the two anchor bolt drilling rigs 62 synchronously, and can also control the raising, lowering, and swung left and right of the drill arms 61 to adjust the vertical height and horizontal position of the anchor bolt drilling rigs 62.

[0028] Specifically, the T-shaped boom mounting base is located at the rear of the lifting platform 30. The rear end of the drill arm 61 is hinged to the left and right ends of the T-shaped boom mounting base. The drill arm 61 can rotate relative to the T-shaped boom mounting base, allowing it to swing left and right on the lifting platform 30, thereby adjusting the horizontal position of the anchor drilling rig 62. The boom rotation cylinder 51 is located inside the drill arm 61 and provides driving force for the left and right swing of the drill arm 61 on the T-shaped boom mounting base.

[0029] The T-shaped boom mount has two L-shaped recessed areas on its left and right sides, and the two boom slewing cylinders 51 are located within these two L-shaped recessed areas. By designing the boom mount in a T-shape, the structural strength of the boom mount is improved, and the protruding part in the middle of the T-shaped boom mount also protects the boom slewing cylinders 51.

[0030] It should be noted that existing anchor bolt trolleys typically have multiple drill arms mounted on the main body via separate swivel seats, resulting in a relatively large lateral width that makes them unsuitable for operation in narrow tunnels. Furthermore, the hydraulic cylinders that drive the trolley's lateral swing are either directly exposed on the outside of the drill arms, making them susceptible to damage from external impacts and disrupting the normal operation of the anchor bolt drilling rig, or the cylinders are mounted directly on the main body. If operators want to control the height adjustment of multiple anchor bolt drilling rigs simultaneously, they must adjust the drill arms of each rig individually, which is cumbersome.

[0031] However, in this application, since the boom slewing cylinder 51 is located inside the drill arm 61, damage to the boom slewing cylinder 51 due to external collisions can be avoided, thus preventing the normal operation of the anchor drilling rig 62 and improving its operational stability. By placing the two boom slewing cylinders 51 within the two L-shaped recessed areas of the T-shaped boom mounting base, the boom slewing cylinders 51 can be better protected. Furthermore, the arrangement of the two drill arms 61 can be more compact, further reducing the width of the anchor trolley and improving its operational flexibility in narrow tunnel environments.

[0032] Furthermore, since the drill arms 61 of the anchor bolt drilling rig 62 are mounted on the lifting platform 30, rather than directly on the vehicle body 10, construction personnel only need to adjust the height of the lifting platform 30 when they encounter a construction scenario requiring simultaneous height adjustment of the two anchor bolt drilling rigs 62. This allows for simultaneous adjustment of the positions of the two drill arms 61, thereby achieving simultaneous adjustment of the positions of the two anchor bolt drilling rigs 62. There is no need to adjust the two drill arms 61 separately, making the operation simpler, faster, and more efficient.

[0033] Furthermore, the T-shaped boom mounting base includes a mounting frame 41 and a T-shaped mounting cover 42. The mounting frame 41 is arranged along the width of the lifting platform 30 and has two first rotary cylinder hinge seats 411 located in the middle. Correspondingly, a second rotary cylinder hinge seat 611 is provided on the inner side of the drill arm 61; one end of the boom rotary cylinder 51 is hinged to the first rotary cylinder hinge seat 411, and the other end is hinged to the second rotary cylinder hinge seat 611 on the inner side of the drill arm. The T-shaped mounting cover 42 is located above the mounting frame 41, forming L-shaped concave areas on both sides; when the boom rotary cylinder 51 drives the drill arm 61 to swing left and right, the boom rotary cylinder 51 is always located within the L-shaped concave area.

[0034] Furthermore, the T-shaped boom mounting base also includes a boom hinge shaft 612. The boom hinge shaft 612 is mounted on the T-shaped mounting cover plate 42. For example, the upper end of the boom hinge shaft 612 is mounted on the T-shaped mounting cover plate 42, and the lower end of the boom hinge shaft 612 is mounted on the lifting platform 30. The drill arm 61 is rotatably mounted on the T-shaped boom mounting base via the boom hinge shaft 612. In one specific embodiment, two boom hinge shafts 612 are symmetrically distributed at the left and right ends of the T-shaped mounting cover plate 41.

[0035] Furthermore, the anchor bolt trolley also includes a boom lifting cylinder 52. The boom lifting cylinder 52 is located below the drill arm 61, providing driving force for vertical height adjustment of the drill arm 61. Compared to placing the boom lifting cylinder 52 on the left or right sides of the drill arm 61, placing it below the drill arm 61 reduces space utilization in the width direction, allowing the anchor bolt trolley to be narrower and further improving its operational flexibility in narrow tunnel environments. In addition, placing the boom lifting cylinder 52 below the drill arm 61 makes the movement of the drill arm 61 smoother, further improving the operational stability of the anchor bolt drilling rig 62.

[0036] Furthermore, the lifting mechanism 20 is disposed between the lifting platform 30 and the vehicle body 10. The lifting mechanism 20 includes a lifting cylinder assembly and a four-bar linkage 23. The lifting cylinder assembly is retractably mounted on the vehicle body, providing driving force for the lifting of the lifting platform 30 on the vehicle body 10. The four-bar linkage 23 is foldably disposed between the vehicle body 10 and the lifting platform 30 to ensure that the lifting platform 30 remains horizontal during lifting, achieving horizontal lifting.

[0037] Furthermore, a front lifting cylinder 21 and two rear lifting cylinders 22 are arranged in a triangle on the vehicle body 10 to ensure that the lifting platform 30 is lifted more smoothly.

[0038] Furthermore, two auxiliary connecting rods 24 are provided on both sides of the front lifting cylinder 21 to further improve the lifting stability of the lifting platform 30.

[0039] Furthermore, the temporary support structure 71 of the anchor bolt trolley is located at the front end of the lifting platform 30. The temporary support structure 71 is hinged to the lifting platform 30, and a geophysical drilling rig 72 is mounted on the temporary support structure 71. The temporary support structure 71 can rotate 90 degrees from above the lifting platform 30 to the front side of the lifting platform 30, allowing the geophysical drilling rig 72 to slide forward and serve as its drill arm. This eliminates the need for an additional drill arm for the geophysical drilling rig 72, making the anchor bolt trolley arrangement more compact and further improving its operational flexibility in narrow tunnel construction environments.
