Description

Technical Field

[0001] This invention belongs to the technical field of drilling equipment for engineering machinery, and specifically relates to a vertical multi-axis water mill drilling machine. Background Technology

[0002] Manual water-cooled drilling rigs are widely used in drilling operations on construction sites. Their feed mechanism is the core component that enables the drill barrel to move up and down and complete the drilling operation. Most existing manual water-cooled drilling rigs use a single gear and rack transmission structure with direct connection. In drilling rigs of a certain weight, the operator needs to apply a force equivalent to the weight of the drilling rig to drive the feed mechanism, resulting in extremely high labor intensity, fatigue from long-term operation, and a serious impact on drilling efficiency.

[0003] Currently, there are existing electric motor-driven automatic feed drilling rigs, such as the automatic drilling rig disclosed in patent document CN201921381717.X. This type of automatic drilling rig uses sector gear transmission to achieve automatic feed, but it cannot adapt to the complex geological conditions of the construction site. When encountering abnormal working conditions such as stuck drill, it cannot be manually intervened in time. Not only is the working efficiency lower than that of manual models, but the equipment manufacturing and maintenance costs are also higher. Therefore, manual water-grind drilling rigs are still the mainstream applicable products for drilling operations on construction sites.

[0004] In response to the technical pain points of existing manual water-grinding drilling rigs' feed mechanisms being labor-intensive and time-consuming to operate, there is an urgent need for a labor-saving feed mechanism that is structurally reliable, significantly labor-saving, and adaptable to complex working conditions on construction sites. This mechanism can reduce the labor intensity of operators, improve drilling efficiency, and ensure operational safety. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A vertical multi-axis water-grinding drill, comprising: The guide rail is vertically arranged and has a rack fixed on its outer periphery; A guide slide is sleeved on the outer periphery of a guide rail, and the side of the guide slide is connected to an installation position for installing a drill barrel and a motor for driving the drill barrel to rotate. The feed mechanism includes a housing, a multi-stage transmission assembly, and a rotary handle; The housing can be detachably connected to the guide slide by bolts, and the housing is provided with an installation cavity; The multi-stage transmission assembly is disposed in the mounting cavity, and the multi-stage transmission assembly includes a first transmission shaft, a second transmission shaft, and a third transmission shaft that are parallel to each other and rotatably mounted in the housing. A first gear for meshing with the rack is fixedly sleeved on the first drive shaft; A second gear and a third gear are fixedly sleeved on the second drive shaft, and the second gear meshes with the first gear; A fourth gear is fixedly sleeved on the third transmission shaft, and the fourth gear meshes with the third gear; The handle drives the third transmission shaft to rotate; It also includes a reversing stop structure.

[0006] Furthermore, the reversing stop structure includes a lug, a stop rod, a stop pin, an anti-detachment support rod, and a limiting protrusion; The lugs are symmetrically fixed to the outer wall of the housing, and the stop rod can be laterally inserted between the two lugs; The stop pin protrudes radially from the peripheral wall of the third transmission shaft, and the stop pin cooperates with the end of the stop rod; The anti-detachment support rod is fixed to the stop rod body, and the limiting protrusion is fixed to the outer wall of the housing and corresponds to the anti-detachment support rod.

[0007] Furthermore, it also includes a locking structure to prevent the guide carriage and drill barrel from falling vertically down the guide rail.

[0008] Furthermore, the locking structure includes a rotating pin threaded onto the side of the guide carriage.

[0009] Furthermore, one end of the third drive shaft extends through the housing to the outside, and the end of the third drive shaft is provided with a socket for inserting a rotating handle.

[0010] Furthermore, the first gear, the second gear, the third gear, and the fourth gear are all spur gears, and their tooth surfaces have undergone quenching treatment.

[0011] Furthermore, the housing is integrally formed from cast iron, and a bearing is installed inside the mounting cavity.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The water-cooled drilling machine using this technical solution has a significant labor-saving effect. The core feed mechanism has been improved in a targeted manner. By setting up a first drive shaft, a second drive shaft, a third drive shaft and matching gears, a two-stage reduction and torque-increasing transmission structure is formed, which replaces the existing automatic transmission structure, greatly reduces the labor intensity of operators, improves work efficiency, and solves the core pain points of the existing manual feed mechanism. The water-grinding drill using this technical solution is suitable for complex working conditions on construction sites and is highly practical. This feeding mechanism retains a manual operation mode, and the operator can directly control the feeding speed and feed amount through the handle. When encountering abnormal working conditions such as drill jamming, manual intervention can be carried out in time to avoid equipment damage. It is suitable for complex geological conditions on construction sites and is more practical than automatic feeding models, meeting the current mainstream market demand for manual water-grinding drills. This water-cooled drilling rig features excellent safety performance and is more convenient to operate. It integrates a reverse stop structure to prevent the feed mechanism from reversing and causing the drill barrel to rotate unexpectedly, thus avoiding potential safety hazards. The rotating handle is replaceable and adjustable in length to suit different operating habits, further enhancing ease of operation. Attached Figure Description

[0014] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0016] like Figure 1 - Figure 6 As shown, a water-grinding drill of the present invention includes a guide rail, a guide carriage 3 used in conjunction with the guide rail 1, and a feeding mechanism; The guide rail 1 is vertically set and a rack 2 is fixed on its outer periphery. The guide slide 3 is sleeved on the outer periphery of the guide rail 1 and can move up and down along the guide rail 1.

[0017] One side of the guide slide 3 is used to install the drill barrel 8 and the motor 7 that drives the drill barrel 8 to rotate. This feed mechanism is installed on the other side of the guide slide 3 and is used to drive the guide slide 3 to move along the guide rail 1 to realize the feeding and lifting of the drill barrel 8.

[0018] The feeding mechanism includes a housing 41, a multi-stage transmission assembly, and a rotating handle 5.

[0019] The housing 41 is made of cast iron and is integrally formed, with a robust structure. It can be detachably connected to the guide slide 3 by bolts, which facilitates installation, disassembly and maintenance. The housing 41 has an installation cavity 411, in which the multi-stage transmission components are set to prevent dust and debris from entering the transmission structure and ensure transmission stability.

[0020] Specifically, the multi-stage transmission assembly includes a first transmission shaft 42, a second transmission shaft 43, and a third transmission shaft 44. All three transmission shafts are rotatably mounted in the mounting cavity 411 of the housing 41 and are arranged parallel to each other to ensure the stability of gear meshing. A first gear 421 is fixedly sleeved on the first drive shaft 42. The first gear 421 is used to mesh with the rack 2 on the guide rail 1. When the first gear 421 rotates, it can drive the entire labor-saving feed mechanism and guide slide 3 to move up and down along the rack 2. A second gear 431 and a third gear 432 are fixedly sleeved on the second drive shaft 43, and the second gear 431 meshes with the first gear 421. A fourth gear 441 is fixedly sleeved on the third drive shaft 44, and the fourth gear 441 meshes with the third gear 432, forming a two-stage reduction and torque increase transmission structure. One end of the third drive shaft 44 extends through the housing 41 to the outside, and the end is provided with a socket 442 for inserting the handle 5. The handle 5 can be selectively inserted into the socket 442 to drive the third drive shaft 44 to rotate.

[0021] The water-grinding drill using this technical solution has a significant labor-saving effect. The core feed mechanism has been improved in a targeted manner. By setting up a first drive shaft 42, a second drive shaft 43, a third drive shaft 44 and matching gears, a two-stage reduction and torque-increasing transmission structure is formed, replacing the existing transmission structure. When applied to a water-grinding drill with a standard weight of 100 kg, the operator's force can theoretically be reduced from the original 100 kg to 11-13 kg, saving up to 60% of the effort. This greatly reduces the labor intensity of the operator, improves work efficiency, and solves the core pain point of the existing manual feed mechanism.

[0022] The insertion hole 442 can be a square hole or other hole-shaped structure. The end of the handle 5 is provided with a matching shape, which can be selectively inserted into the insertion hole 442. The operator drives the third transmission shaft 44 to rotate by rotating the handle 5, which in turn drives the multi-stage transmission components to operate, and finally realizes the movement of the guide carriage 3.

[0023] A support base 9 is provided at the bottom of the guide rail 1. The support base 9 provides support for the upper components. The support base 9 is rectangular or other irregularly shaped to form a stable structure.

[0024] The handle 5 is a replaceable structure, and the length of the handle 5 is adjustable. Operators can replace the handle 5 with different lengths according to their own height, operating habits and work requirements, which makes it easier to apply torque and further reduces the difficulty of operation.

[0025] To improve operational safety and prevent the drill barrel 8 from rotating during operation or pauses, this feed mechanism is also equipped with a reverse stop structure.

[0026] like Figure 2 , Figure 3 As shown, the feeding mechanism also includes a reversing stop structure, which includes a lug 45, a stop rod 46, a stop pin 443, an anti-detachment support rod 461, and a limiting protrusion 47. Specifically, the lugs 45 are symmetrically fixed on the outer side wall of the housing 41, and the stop rod 46 can be laterally moved between the two lugs 45. The stop pin 443 is radially outwardly protruding on the peripheral wall of the third drive shaft 44. The stop pin 443 cooperates with the end of the stop rod 46 to prevent the third drive shaft 44 from reversing, thereby realizing the reversal stop of the third drive shaft 44 and the entire feed mechanism.

[0027] The anti-detachment support rod 461 is fixedly mounted on the rod body of the stop rod 46, and the limiting protrusion 47 is fixedly mounted on the outer wall of the housing 41 and is correspondingly mounted to the anti-detachment support rod 461. When the stop rod 46 moves and rotates toward the third drive shaft 44, the anti-detachment support rod 461 is located inside the limiting protrusion 47, thereby positioning the stop rod 46 and preventing the stop rod 46 from moving back during drilling operations.

[0028] The water-grinding drill using this technical solution is suitable for complex working conditions on construction sites and is highly practical. The feeding mechanism retains a manual operation mode, and the operator can directly control the feeding speed and feed amount through the rotary handle 5. When encountering abnormal working conditions such as drill jamming, manual intervention and adjustment can be made in a timely manner to avoid equipment damage. It is suitable for complex geological conditions on construction sites and is more practical than automatic feeding models, meeting the current mainstream market demand for manual water-grinding drills.

[0029] Meanwhile, a locking structure is provided, which includes a rotating pin 6 threaded on the side of the guide slide 3. The rotating pin 6 can be manually turned and serves as a safety device to prevent the drill barrel 8, the guide slide 3, and the motor 7 from falling vertically along the guide rail 1 together. When the rotating pin 6 is screwed in, its head abuts against the side of the guide rail 1, locking the guide slide 3 and the guide rail 1 together and preventing accidents.

[0030] In this embodiment, the first gear 421, the second gear 431, the third gear 432 and the fourth gear 441 are all spur gears, and the tooth surfaces of the gears have been hardened, resulting in high hardness and strong wear resistance. This can effectively improve the stability and service life of the transmission structure and prevent the gears from wearing out too quickly due to long-term operation.

[0031] The improved feed mechanism is compact and reliable, easy to install and maintain. The multi-stage transmission components are integrated into the housing 41, resulting in a compact overall structure and small size. It can be detachably connected to the guide carriage 3 of the existing manual water grinder by bolts, which facilitates the upgrading and transformation of existing equipment. At the same time, the housing 41 is made of cast iron, and the gears are hardened, resulting in stable transmission, long service life, and low maintenance costs.

[0032] The housing 41 is integrally formed from cast iron. The mounting cavity 411 of the housing 41 is provided with bearings for supporting the first drive shaft 42, the second drive shaft 43 and the third drive shaft 44. The bearings are interference-fitted with the drive shafts to reduce transmission friction.

[0033] It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
