Description

Technical Field

[0001] This application relates to the field of rock drilling rig technology, and more particularly to a sliding plate structure used on a rock drilling rig propeller. Background Technology

[0002] A rock drilling rig is a machine used to drill holes in tunnel walls. During operation, the rig uses a pusher to transport the rock drill assembly to the vicinity of the wall for drilling. The pusher is equipped with a slide rail and a slider. The rock drill assembly is fixed to the slider via the slide rail. When the position of the rock drill assembly needs to be changed, the slider moves the assembly along the length of the slide rail. However, in harsh working conditions or if workers do not clean the rig in a timely manner, dirt, sand, and other debris can adhere to the slide rail, causing the pusher to operate unevenly and increasing the pressure on the pusher.

[0003] Currently, to ensure smooth sliding of the slider on the guide rail, the guide rail is usually flushed with water after drilling. However, it is impossible to flush the guide rail during drilling. If the drilling process is long, the hardened mud and sand will seriously affect the efficiency of subsequent cleaning. In addition, the height of the pusher makes it difficult to clean the guide rail manually. Therefore, a sliding plate structure that can clean the guide rail while the rock drill components are moving is needed. Utility Model Content

[0004] One objective of this application is to provide a sliding plate structure for use on a rock drilling rig propeller that can solve at least one of the defects in the aforementioned background art.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a sliding plate structure for use on a rock drilling rig pusher, comprising a sliding plate body and a slide rail, a sliding component slidably mounted on the slide rail, the sliding plate being fixedly mounted on the upper end of the sliding component, the sliding plate being used to mount a rock drilling machine component, the sliding plate being provided with a screw hole, a connector seat being installed in the screw hole, the connector seat being connected to the water pipe of the rock drilling machine component; the bottom of the sliding plate being provided with at least one interface communicating with the interior of the connector seat, a water outlet connector being installed in the interface, the water outlet of the water outlet connector facing the slide rail.

[0006] With the above settings, the slider can move synchronously to drive the rock drill assembly. During the drilling process of the rock drill assembly, the water outlet of the slide plate can spray water to clean the surface of the slide rail, so that the mud, sand and other materials attached to the slide rail can be removed from the slide rail, ensuring that the slider can move smoothly on the slide rail.

[0007] Preferably, there are two interfaces, one on each side of the slide plate. This configuration allows for simultaneous cleaning of both sides of the slide rail via the interfaces on both sides of the slide plate, thereby improving the cleaning efficiency of the slide rail.

[0008] Preferably, the water outlet connector is plugged into the interface, and the mating surfaces of the water outlet connector and the interface are provided with mutually mating threaded structures. This design improves the installation stability of the water outlet connector and the interface through the threaded structure. When the water outlet connector is damaged, it can be unscrewed and replaced with a new one, thereby increasing the repair speed of the water outlet connector.

[0009] Preferably, the slide plate has a water flow channel inside, which is similar to a T-junction structure. The water flow channel includes one inlet and two outlets. The inlet is connected to the connector seat, and the two outlets are connected to the two interfaces respectively. This configuration allows the interfaces on both sides of the slide plate to be simultaneously connected to the connector seat via the water flow channel. When water from the rock drill assembly's water pipe enters the water flow channel, it is divided into two streams that flow into different interfaces, thus cleaning both sides of the slide rail with a single water delivery. Furthermore, the water flow channel is fixedly located inside the slide plate, eliminating the need for external water pipes, saving space in the propeller, and improving the safety of water delivery.

[0010] Preferably, there are two sliding components, which are installed on the slide rail in a front-to-back sequence. Each end of the slide plate is fixedly connected to its corresponding sliding component. This arrangement further reduces the material cost of the sliding components, lowers their overall weight, and allows the slide plate to be supported by the front-to-back sliding components. Furthermore, the positions of the two sliding components can be adjusted according to actual needs.

[0011] Preferably, the sliding assembly includes two sliders, which are respectively mounted on both sides of the slide rail. This configuration allows the slide plate to limit the distance between the two sliders, with the sliders on both sides supporting each other to ensure the sliders are stably mounted on the slide rail.

[0012] Preferably, the slider includes an upper pressure plate and a lower pressure plate, both of which have multiple aligned mounting holes. Fasteners for pressing the upper and lower pressure plates together are installed in these mounting holes. This modular design simplifies the manufacturing process and reduces costs; either the upper or lower pressure plate can be replaced individually if it becomes worn.

[0013] Preferably, the upper pressure plate is provided with a first mounting portion, and the lower pressure plate is provided with a second mounting portion. The first mounting portion and the second mounting portion cooperate to form a sliding cavity. The slider is slidably mounted on the slide rail through the sliding cavity, and the included angle between the first mounting portion and the second mounting portion is 90°. This configuration allows for sliding cooperation between the first mounting portion and the slide rail, and the 90° angle ensures that the first mounting portion and the second mounting portion are parallel to the mating surface of the slide rail, thereby improving the sliding stability of the slider.

[0014] Preferably, the mounting hole is elongated, and its opening is inclined to the side of the upper or lower pressure plate. This configuration improves the connection stability of the upper and lower pressure plates, and the "self-locking angle" (similar to wedge self-locking) created by the inclination reduces the probability of fastener loosening under vibration. In addition, it reduces local stress concentration, lowering the risk of damage to the upper and lower pressure plates.

[0015] Preferably, both the first mounting portion and the second mounting portion are provided with mounting grooves, and a liner for contacting the slide rail is installed in the mounting groove. This arrangement ensures that when the slider moves, the liner directly contacts the slide rail, preventing wear on the slider. When the liner wears out, it can be directly replaced with a new liner, thereby reducing the maintenance and repair costs of the slider.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: The water outlet connector sprays water during the drilling process of the rock drill assembly to clean the surface of the slide rail, removing dirt, sand, and other materials adhering to the rail and ensuring smooth movement of the slider. The water flow channel outlets are connected to interfaces on both sides, allowing for complete cleaning of both sides of the slide rail with a single water flow. Furthermore, the water flow channel is fixed inside the slider, eliminating the need for external water pipes, saving space in the propeller, and improving the safety of water delivery.

[0017] The mounting holes are angled and elongated, improving the connection stability of the upper and lower pressure plates, reducing localized stress concentration, and lowering the risk of damage to both plates. The slider directly contacts the slide rail via a liner to prevent wear; when the liner wears, it can be directly replaced, thus reducing maintenance costs. This design allows for easy cleaning of sand and mud from the slide rail, ensuring smooth operation of the propeller. Attached Figure Description

[0022] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0024] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0026] One aspect of this application provides a sliding plate structure for use on a rock drilling rig propeller, one preferred embodiment of which is, for example... Figure 1 and Figure 2As shown, the device includes a slide plate 1 body and a slide rail 100. A sliding component 200 is slidably mounted on the slide rail 100. The slide plate 1 is fixedly mounted on the upper end of the sliding component 200. The slide plate 1 is used to mount the rock drill component. The slider 4 can move synchronously to drive the rock drill component to move closer to the rock wall for drilling. The slide plate 1 is provided with a screw hole, and a connector seat 2 is installed in the screw hole. The connector seat 2 is connected to the water pipe of the rock drill component. The bottom of the slide plate 1 is provided with an interface 11 that is connected to the inside of the connector seat 2. A water outlet connector 3 is installed in the interface 11, and the water outlet of the water outlet connector 3 faces the slide rail 100.

[0027] It should be understood that in the existing technology, the slide rail 100 cannot be cleaned when the rock drill assembly is working. Usually, the slide rail 100 needs to be cleaned manually after the rock drill assembly is stopped. However, when the rock drill assembly is working, a large amount of mud and sand will adhere to the slide rail 100, which will obstruct the movement of the rock drill assembly.

[0028] In this application, the cleaning of the slide rail 100 does not rely on manual labor. The slide plate 1 is equipped with a water outlet 3 that is connected to the water pipe of the rock drill component. During the operation and movement of the rock drill component, the water outlet 3 automatically sprays water to clean the surface of the slide rail 100, so that the mud, sand and other materials attached to the slide rail 100 are removed from the slide rail 100, ensuring that the slider 4 can move smoothly on the slide rail 100.

[0029] Specifically, such as Figure 1 As shown, there are two interfaces 11, which are respectively installed on both sides of the slide plate 1. When the slide rail 100 needs to be cleaned, both sides of the slide rail 100 can be cleaned simultaneously through the water outlet connectors 3 on both sides, thereby improving the cleaning efficiency of the slide rail 100. Of course, in practical applications, the number of interfaces 11 can be increased according to actual needs to improve the cleaning effect of the slide rail 100.

[0030] Furthermore, the water outlet connector 3 and the interface 11 are directly connected via a plug-in fit, and a mutually cooperating limiting structure is provided between the water outlet connector 3 and the interface 11 to ensure that the water outlet connector 3 can be stably installed on the interface 11. Specific limiting structures include, but are not limited to, interference fits and threaded fits. Taking a threaded fit as an example, mutually cooperating threads are provided on the mating surfaces of the water outlet connector 3 and the interface 11. When the water outlet connector 3 is damaged, it can be unscrewed and replaced with a new one, thereby improving the speed of replacement and maintenance of the water outlet connector 3.

[0031] In this embodiment, as Figure 1As shown, the slide plate 1 has a water flow channel 12 inside. The water flow channel 12 is similar to a T-junction structure, including one inlet and two outlets. The inlet of the water flow channel 12 is connected to the connector seat 2, and the two outlets of the water flow channel 12 are connected to the interfaces 11 located on both sides. In this way, the interfaces 11 on both sides of the slide plate 1 can be simultaneously connected to the connector seat 2 through the water flow channel 12. When the water in the water pipe of the rock drill assembly enters into the water flow channel 12, it can be divided into two streams and enter different interfaces 11, so that the cleaning of both sides of the slide rail 100 can be completed with one water supply. In addition, the water flow channel 12 is fixedly set inside the slider 4, which can avoid the need for external water pipes, not only saving space for the propeller, but also improving the safety of water transportation.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, there are two sliding components 200. The two sliding components 200 are installed on the slide rail 100 in front and behind order. The front and rear ends of the slide plate 1 are fixedly connected to their respective sliding components 200, thereby reducing the material cost of the sliding components 200. The sliding components 200 only support the two ends of the slide plate 1, which enables the slide plate 1 to have good balance and stability.

[0033] In addition, dividing the traditional one-piece sliding component 200 into two smaller sliding components 200 can effectively reduce the overall weight of the sliding component 200. The front and rear sliding components 200 can jointly support the skateboard 1, and the positions of the two sliding components 200 can be adjusted according to actual needs. When the size of the skateboard 1 changes, the distance between the two sliding components 200 can be changed to accommodate skateboards of different sizes.

[0034] Specifically, such as Figure 2 As shown, the sliding assembly 200 includes two sliders 4, which are respectively installed on both sides of the slide rail 100. After the slide plate 1 is fixedly connected to the sliders 4, the distance between the two sliders 4 can be limited so that the two sliders 4 can support each other and the distance between the two sliders 4 can be adapted to the slide rail 100, ensuring that the sliders 4 can be stably installed on the slide rail 100.

[0035] In this embodiment, as Figure 2 and Figure 3 As shown, the slider 4 includes an upper pressure plate 41 and a lower pressure plate 42. The upper pressure plate 41 and the lower pressure plate 42 are provided with a plurality of mutually aligned mounting holes 300. Fasteners for pressing the upper pressure plate 41 and the lower pressure plate 42 are installed in the mounting holes 300. By setting the slider 4 as a split structure, the manufacturing process can be effectively simplified and the manufacturing cost reduced. If either the upper pressure plate 41 or the lower pressure plate 42 is worn, it can be replaced separately.

[0036] Specifically, such as Figure 3 As shown, the upper pressure plate 41 is provided with a first mounting part 410, and the lower pressure plate 42 is provided with a second mounting part 420. When the upper pressure plate 41 and the lower pressure plate 42 are pressed together, the first mounting part 410 and the second mounting part 420 cooperate to form a sliding cavity. The slider 4 is slidably mounted on the slide rail 100 through the sliding cavity, and the included angle between the first mounting part 410 and the second mounting part 420 is 90° to ensure that the first mounting part 410 and the second mounting part 420 can be parallel to the mating surface of the slide rail 100, thereby improving the sliding stability of the slider 4.

[0037] In this embodiment, as Figure 3 As shown, the mounting hole 300 is elongated, and the opening of the mounting hole 300 is inclined to the side of the upper pressure plate 41 or the lower pressure plate 42 to improve the connection stability of the upper pressure plate 41 and the lower pressure plate 42. The "self-locking angle" (similar to wedge self-locking) brought about by the inclined opening of the mounting hole 300 can reduce the probability of fastener loosening under vibration environment. In addition, the elongated mounting hole 300 can also reduce local stress concentration and reduce the risk of damage to the upper pressure plate 41 and the lower pressure plate 42.

[0038] Furthermore, such as Figure 3 As shown, mounting grooves 400 are provided on the mating surfaces of the first mounting part 410 and the second mounting part 420. A liner 41 for contacting the slide rail 100 is installed in the mounting groove 400. When the slider 4 moves, the liner 41 directly contacts the slide rail 100 to prevent the slider 4 from being worn. When the liner 41 is worn, a new liner 41 can be directly replaced, thereby reducing the maintenance cost of the slider 4.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
