Abstract
Description
Technical Field
[0001] This utility model relates to the field of rock drilling equipment technology, and more specifically, to a multi-layer oil pipe guiding mechanism for rock drilling equipment. Background Technology
[0002] During the operation of the rock drilling rig, the hydraulic oil pipes at the tail of the rock drill need to reciprocate with the rock drill. Due to the large number of oil pipes, they are prone to tangling, squeezing, deformation and wear, which can lead to oil pipe failure and affect the use of the equipment.
[0003] To address issues such as entanglement, compression deformation, and wear that arise when rock drills have a large number of tubing pipes, current solutions primarily involve increasing the number of tubing guide discs. For example, a dual-tubing disc solution increases the number of discs to two, ensuring that each disc has only a single layer of tubing, thus preventing entanglement and compression. Alternatively, a dual-layer tubing roller solution can be used, which, while maintaining the same height and length, incorporates inner and outer layers of tubing rollers to meet the needs of guiding more tubing.
[0004] Both of the above solutions still achieve single-layer independent arrangement when there are many oil pipes, avoiding problems such as tangling, compression deformation, and wear. However, they also increase the space size of the oil pipe turntable. Solution 1 causes an increase in length, and Solution 2 causes an increase in diameter, ultimately increasing equipment costs and reducing operational flexibility. Utility Model Content
[0005] To address the shortcomings of multi-layered oil pipe mechanisms in rock drills, such as large size, high cost, and low operational flexibility, this solution provides a multi-layered oil pipe guiding mechanism for rock drill equipment. By combining guide rollers and guide rollers, it achieves smaller size, lower equipment cost, and higher operational flexibility with the same number of oil pipes.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] This utility model discloses a multi-layer oil pipe guiding mechanism for a rock drilling equipment, comprising a sliding base, an oil pipe guiding base, a guide roller, and a guide wheel; the sliding base is linearly connected to the propulsion beam of the rock drilling equipment, the oil pipe guiding base is fixed to the sliding base, and the guide roller is rotatably connected to the oil pipe guiding base;
[0008] The guide rollers are arranged on the oil pipe guide base with the guide drum as the center.
[0009] Furthermore, the oil pipe guide base includes a lower base and an upper end cover, and the guide roller and guide wheel are disposed between the lower base and the upper end cover.
[0010] Furthermore, the outer ring of the guide roller is provided with a plurality of first guide grooves, the grooves of the first guide grooves being matched with the oil pipes.
[0011] Furthermore, the radius of the guide roller is matched with the minimum bending radius of the oil pipe.
[0012] Furthermore, the dimensions of the first guide grooves decrease sequentially from bottom to top.
[0013] Furthermore, the guide roller includes a roller and a connecting shaft, the connecting shaft being located at the center of the roller, and the two ends of the connecting shaft being fixedly connected to the lower base and the upper end cover, respectively.
[0014] Furthermore, the outer ring of the roller is provided with a plurality of second guide grooves, the grooves of the second guide grooves being matched with the oil pipes.
[0015] Furthermore, the dimensions of the second guide grooves decrease sequentially from bottom to top.
[0016] Furthermore, lower ear plates extend symmetrically from both sides of the lower base, and upper ear plates extend symmetrically from both sides of the upper end cover. A limiting member located outside the oil pipe is provided between the lower ear plate and the upper ear plate on the same side.
[0017] Furthermore, the limiting component includes several limiting rollers, the two ends of which are respectively connected to the lower base and the upper end cover.
[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0019] The multi-layer tubing guide mechanism of this utility model, through the combination of guide rollers and guide rollers, wherein the guide rollers are arranged around the guide rollers, can ensure that each tubing is arranged in a single layer on the turntable, solving problems such as entanglement, extrusion deformation, and wear. Moreover, with the same number of tubing, the tubing guide mechanism has a smaller spatial size, lower equipment cost, and higher operational flexibility. Attached Figure Description

[0032] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] While the existing multi-pipe distribution structure of rock drilling equipment can avoid phenomena such as entanglement, compression deformation, and wear, it also increases the space size of the pipe turntable, leading to an increase in the final equipment cost and a reduction in operational flexibility.
[0034] like Figure 1 and Figure 2 As shown, this embodiment provides a multi-layer tubing guide mechanism for a rock drilling equipment, including a sliding base 1, a tubing guide base 2, a guide roller 3, and a guide roller 4; the sliding base 1 is linearly connected to the propulsion beam of the rock drilling equipment, the tubing guide base 2 is fixed to the sliding base 1, and the guide roller 3 is rotatably connected to the tubing guide base 2; the guide roller 4 is arranged on the tubing guide base 2 with the guide roller 3 as the center.
[0035] The above setup solves the problems of multiple oil pipes being easily tangled, deformed by compression, and worn. Moreover, with the same number of oil pipes, the oil pipe guiding mechanism has a smaller spatial size, lower equipment cost, and greater operational flexibility.
[0036] Specifically, such as Figure 3 and Figure 4 As shown, the oil pipe guide base 2 includes a lower base 21 and an upper end cover 22. The upper end cover 22 is directly opposite the lower base 21. The guide roller 3 and the guide roller 4 are both arranged in the area between the lower base 21 and the upper end cover 22.
[0037] To ensure that the oil pipes 5 can be arranged in a single layer without being squeezed together, the outer ring of the guide roller 3 is provided with several first guide grooves 31, the groove specifications of which are matched with the oil pipes 5.
[0038] It should be noted that the radius of the guide roller 3 must match the minimum bending radius of the oil pipe 5 to ensure that the oil pipe 5 will not be flattened due to an excessively small bending radius.
[0039] In one specific implementation, when the oil pipes 5 have different sizes, since the tightening force is greater for the larger diameter oil pipe when tightening the straightness of the same oil pipe, the smaller oil pipe will generate pressure in the direction perpendicular to the base when tensioned. The specifications of the first guide groove 31 decrease sequentially from the lower base 21 to the upper end cap 22, that is, the specifications of the oil pipes 5 are arranged in a progressively smaller manner from bottom to top.
[0040] Specifically, the guide roller 4 includes a roller 41 and a connecting shaft 42. The connecting shaft 42 is located at the center of the roller 41, and the two ends of the connecting shaft 42 are fixedly connected to the lower base 21 and the upper end cover 22, respectively.
[0041] Furthermore, the outer ring of the roller 41 is provided with several second guide grooves 411. The groove of the second guide groove 411 matches the oil pipe 5 to ensure that the oil pipe 5 can be arranged in a single layer without squeezing each other.
[0042] In one specific implementation, when the oil pipes 5 are of different sizes, the specifications of the second guide groove 411 decrease sequentially from the lower base 21 to the upper end cap 22, so as to ensure a single-layer arrangement of oil pipes 5 of different specifications.
[0043] In this embodiment, lower ear plates extend symmetrically from both sides of the lower base 21, and upper ear plates extend symmetrically from both sides of the upper end cover 22. A limiting member located outside the oil pipe 5 is provided between the lower ear plate and the upper ear plate on the same side.
[0044] By setting the limiting component, the outermost oil pipe can be prevented from detaching during the up-and-down reciprocating motion.
[0045] Specifically, the limiting component can be in the form of a limiting roller 23. Of course, the structure of the limiting component is not limited to this, and other structures that can achieve the limiting function can also be used.
[0046] The number of limiting rollers 23 can be set to multiple, such as 2, 3, 4, etc. The bottom end of the limiting roller is connected to the lower base 21, and the top end of the limiting roller is connected to the upper end cover 22.
[0047] When the outermost oil pipe 5 reciprocates with the rock drilling equipment, it remains within the second guide groove 411 of the guide roller 4 due to the obstruction of the limit roller.
[0048] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
