Description

Technical Field

[0001] The utility model relates to the technical field of rock drill maintenance, in particular to a lubricating oil injection component for rock drill measurement and control. Background Art

[0002] The rock drill measurement and control system can detect the working data of the rock drill and automatically generate a test report based on the detected data to assist staff in quickly and accurately understanding the performance of the rock drill and provide a basis for equipment maintenance, improvement and selection.

[0003] During rock drill testing by the measurement and control system, deterioration in the lubricating oil quality is one of the reasons the measurement and control system reports faults, so the rock drill's lubricating oil often needs to be replaced. The first step in replacing the lubricating oil is to unscrew the corresponding plug. However, when unscrewing the plug to expel the old lubricating oil, the high pressure created by the high pressure environment in the rock drill's lubricating oil chamber can push most of the unscrewed plug out of the corresponding oil hole, thereby increasing the risk of the plug being lost and the probability of the plug being sprayed into the worker's face, causing injury. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the lubricating oil plug scatters due to the high pressure inside the oil chamber, thereby affecting the reset of the plug and the personal safety of the workers, and to provide a lubricating oil injection assembly for measuring and controlling a rock drill.

[0009] As a further optimization of the lubricating oil injection assembly for rock drill measurement and control of the utility model: the docking seat and the rotating column are hinged via an articulated support so that the rotating column can flip around the articulated support.

[0010] As a further optimization of the lubricating oil injection assembly for rock drill measurement and control of the utility model: a top pressure block is provided in the hinged support on the docking seat, and the top pressure block is made of elastic rubber to prevent the rotating column from flipping around the hinged support.

[0011] As a further optimization of the lubricating oil injection assembly for rock drill measurement and control of the utility model: an anti-slip sleeve is fixedly provided on the outer peripheral surface of the rotating column, and protective protrusions are provided on the outer peripheral surface of the anti-slip sleeve.

[0019] In order to better understand the present invention, the content of the present invention is further explained below in conjunction with embodiments, but the content of the present invention is not limited to the following embodiments.

[0020] like Figure 1-3 As shown, a lubricating oil injection assembly for rock drill measurement and control includes a limiting disk 2, a knob 3 rotatably arranged at the center of the limiting disk 2, and a plurality of telescopic rods 1 arranged at the outer edge of the end face of the limiting disk 2. The plurality of telescopic rods 1 are vertically arranged and evenly distributed. The plurality of vertically arranged telescopic rods 1 form a cylindrical shape with uniform spacing on the outer periphery. After being matched with the limiting disk 2, they can form a closed cover with uniform spacing, and the lower ends of the plurality of telescopic rods 1 are provided with a magnetic sheet 101. The magnetic sheet 101 can position the formed closed cover to the surface at the corresponding position of the rock drill body 4 to limit the injection of the plug 5, thereby reducing the probability of the plug 5 being lost, and also reducing the probability of the plug 5 being injected onto the staff and causing harm to the staff. Specifically, it limits the plug 5 pushed out by the high pressure inside the oil chamber.

[0021] The telescopic rod 1 includes a telescopic cylinder 103 vertically fixed to the limiting plate 2. A telescopic column 102 slides vertically within the telescopic cylinder 103. Specifically, the end of the telescopic column 102 that extends beyond the telescopic cylinder 103 is fixedly connected to a magnetic plate 101. The magnetic plate 101 engages the surface near the oil hole 6 of the rock drill body 4, thereby cooperating with the telescopic rod 1 to define the position of the limiting plate 2. The combination of the telescopic cylinder 103 and the telescopic column 102 enables the vertical displacement of the knob 3, supported by the limiting plate 2, to accommodate changes in position during the removal of the plug 5, thereby preventing equipment failures caused by structural interference.

[0022] A spring 104 is provided between the telescopic cylinder 103 and the telescopic column 102, and when the magnetic sheet positions the telescopic column 102 on the surface near the oil hole 6 of the rock drill body 4, the spring 104 will be able to pull the telescopic cylinder 103 to accommodate the telescopic column 102 based on the telescopic column 102 positioned by the magnetic sheet 101, thereby driving the limiting plate 2 toward the surface of the rock drill body 4. Subsequently, the knob 3 can be pushed by the limiting plate 2 to stably connect with the plug 5, so that the staff can unscrew the plug 5 for subsequent lubricating oil replacement.

[0023] The knob 3 includes a docking seat 301 that rotates vertically at the center of the limiting disk 2. A rotating post 302 is provided on the upper side of the docking seat 301. The rotating post 302 facilitates rotation of the docking seat 301, thereby providing a torsional force for screwing the plug 5 in and out. The lower side of the docking seat 301 can be magnetically plugged with a docking post 306, making it easy for the user to replace the docking post 306 with a different lower end shape to accommodate plugs 5 with different grooves.

[0024] The rotating column 302 and the docking seat 301 are hingedly connected by an articulated support, allowing the rotating column 302 to rotate in one direction around the articulated support. Rotating the rotating column 302 at different angles can change the torque of the rotating docking seat 301, allowing the user to select different torques based on the friction between the plug 5 and the oil hole 6 to easily remove the plug 5 from the oil hole 6 or stably and securely screw the plug 5 into the oil hole 6. The articulated support is composed of a support fixed to the upper end surface of the docking seat 301 and a connecting block fixed to the end surface of the rotating column 302. The articulated support is provided with a pressing block 303 that presses against the connecting block. The pressing block 303 presses against the rotating column 302 to prevent the rotating column 302 from rotating, thereby positioning the rotating column 302 to a certain extent for easy adjustment and control by the operator. The pressing block 303 can be made of an elastic rubber block.

[0025] An anti-slip sleeve 305 is provided on the outer circumference of the rotating column 302. Specifically, the anti-slip sleeve 305 is provided on the outer circumference of the rotating column 302. The anti-slip convex points can facilitate the staff to quickly rotate the rotating column 302 under a small torque, thereby facilitating the staff to quickly screw the plug 5 out of the oil hole 6, or quickly screw the plug 5 into the oil hole 6.

[0026] A support pin 304 is provided at the end of the rotating column 302 that faces away from the limiting plate 2. The support pin 304 is configured to press against a worker's hand, allowing the worker to easily rotate the rotating column 302 while their hand is supported. This allows the user to effortlessly remove the plug 5 from the oil hole 6 or easily insert the plug 5 into the oil hole 6. An elastic rubber layer is fixedly provided on the upper side of the support pin 304 to enhance user comfort to a certain extent.

[0027] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
