Description

Technical Field

[0001] The utility model relates to the technical field of drill rod supporting devices, in particular to a drill rod supporting device with a modular design, and in addition, particularly to a rock drilling trolley propulsion device adopting the drill rod supporting device. Background Art

[0002] At present, the drilling and blasting method is mainly used in tunnel and mining projects. Among them, drilling with a drilling rig is a common construction method. Figure 1 As shown, the rock drill 2 of the rock drilling trolley propulsion device is connected to the tail of the drill rod 4 through the connecting sleeve 3, and the drill bit 9 is installed at the head of the drill rod 4. The drill rod 4 is supported and positioned by a drill support. The drill support generally includes an intermediate drill support 7, a front drill support 8 and a hydraulic drill clamp 10. The intermediate drill support 7 is used to support the middle of the drill rod 4, and the front drill support 8 and the hydraulic drill clamp 10 are used to support the front two points of the drill rod 4. The hydraulic drill clamp 10 has the function of supporting and disassembling the drill rod. When drilling, the propulsion beam 1 is used as a slide rail, and the rock drill 2 slides forward at a speed twice that of the intermediate drill support 7 by means of the propulsion cylinder 5 and the wire rope 6, so as to realize the function of propulsion and drilling of the drill rod 4, thereby realizing the face drilling operation. At present, these three drill supports are all independently designed, and the versatility of the drill supports is poor. In addition, the existing drill support is divided into two types according to the different fixing methods of the guide sleeve: clamp fixing and bolt fixing. For example, patent CN110219604A discloses a clamp-fixed drill support, which has the following problems: 1) it is easy to scrape the tunnel contour, arch frame and anchor net, etc., causing the clamp to fall off; 2) the clamp causes the upper end size of the drill support to be larger, that is, the edge center distance is larger, resulting in a larger external insertion angle, which leads to serious over-excavation and increased construction costs; patent CN209586284U discloses a bolt-fixed drill support. Since the guide sleeve is a consumable part and needs to be replaced frequently, the existing bolt-fixed drill support has the problems of inconvenient bolt removal and easy damage to the thread.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Reference Figures 2 to 9The preferred embodiment of the present application provides a drill pipe supporting device with a modular design, including a drill supporting support 11, a guide sleeve 12, a limit plate 13, a limit rod 14 and a pin 15. The drill supporting support 11 is installed on the base of the intermediate drill supporting device, the base of the front drill supporting device or the base of the hydraulic drill clamp through a connecting bolt 16, thereby forming an intermediate drill supporting device, a front drill supporting device or a hydraulic drill clamp, realizing the modular design of the drill supporting device and improving the versatility. The guide sleeve 12 is embedded and installed in the inner cavity of the drill support support 11. A positioning hole is provided on the guide sleeve 12 for positioning and supporting the drill rod. The limit plate 13 is inserted into the inner cavity of the drill support support 11 and is padded under the guide sleeve 12. The bottom surface of the inner cavity of the drill support support 11 is provided with a first through hole 111 that penetrates in a radial direction. A slot 131 aligned with the first through hole 111 is provided on the bottom surface of the limit plate 13. A limiting space is formed after the first through hole 111 is aligned with the slot 131. The limiting rod 14 is inserted into the limiting space from one side and then extends out from the other side. A second through hole 141 is provided on the extended end of the limiting rod 14. The latch 15 is inserted into the second through hole 141 to fix the limiting rod 14. It can be understood that when the drill rod support device needs to be installed, the guide sleeve 12 is first installed into the inner cavity of the drill support support 11, and then the limit plate 13 is inserted and padded under the guide sleeve 12, and the slot 131 is aligned with the first through hole 111, and then the limit rod 14 is inserted from one side of the drill support support 11 into the limit space formed by the first through hole 111 and the slot 131 and extended from the other side, and then the pin 15 is inserted into the second through hole 141 of the limit rod 14; and when the drill rod support device needs to be disassembled, the pin 15 is first pulled out, and then the limit rod 14 is taken out, and then the limit plate 13 is taken out, and then the guide sleeve 12 is taken out; the assembly and disassembly process of the device is simple and fast, and it is convenient to quickly replace the guide sleeve 12. Among them, the axial direction refers to the axial direction of the drill rod, that is, the front and rear direction of the drill support, and the radial direction refers to the left and right direction of the drill support. In addition, the pin 15 preferably adopts an R-type pin, which is relatively low in cost.

[0032] It can be understood that the modularly designed drill pipe supporting device of this embodiment embeds the guide sleeve 12 into the inner cavity of the drill supporting support 11, and inserts the limit plate 13 to pad under the guide sleeve 12, thereby limiting the upper and lower positions of the guide sleeve 12 to prevent it from moving up and down in the drill supporting support 11. At the same time, a first through hole 111 is provided on the bottom surface of the inner cavity of the drill bit support 11 and penetrates in the radial direction, and a slot 131 is provided on the bottom surface of the limit plate 13 and is aligned with the first through hole 111. After the first through hole 111 is aligned with the slot 131, a limit space is formed. The limit rod 14 is inserted into the limit space from one side and then extends from the other side, and a second through hole 141 is provided on the extended end of the limit rod 14. The latch 15 is inserted into the second through hole 141 to fix the limit rod 14, so that the limit rod 14 axially limits the limit plate 13, thereby realizing the axial limit of the guide sleeve 12 and preventing it from moving forward and backward in the drill bit support 11. When the guide sleeve 12 needs to be replaced, the latch 15 is first pulled out, and then the limit plate 13 is taken out, and the guide sleeve 12 can be taken out. The assembly and disassembly of the overall device is very convenient. Moreover, the entire drill support device is a modular component, which can be connected to the intermediate drill support base, the front drill support base or the hydraulic drill clamp base through the connecting bolts 16 to form an intermediate drill support, a front drill support or a hydraulic drill clamp, thereby improving the versatility of the drill support.

[0033] It can be understood that the drill support support 11 includes a bottom plate 112, a cover plate 113, a short sealing plate 114 and a long sealing plate 115. The bottom plate 112 is provided with four light holes 110. The connecting bolts 16 are fixedly installed on the middle drill support base, the front drill support base or the hydraulic drill clamp base after passing through the light holes 110. The cover plate 113 is fixed on the bottom plate 112. The cover plate 113 and the bottom plate 112 form a storage space to embed and install the guide sleeve 12. The short sealing plate 114 and the long sealing plate 115 are respectively installed on the front and rear end surfaces of the cover plate 113. The long sealing plate 115 is used to axially limit one end of the guide sleeve 12 to prevent the guide sleeve 12 from coming out. The short sealing plate 114 is used to axially limit the other end of the guide sleeve 12 after the limiting plate 13 is placed under the guide sleeve 12. The first through hole 111 is provided on the upper surface of the bottom plate 112. When the guide sleeve 12 is embedded and installed, the guide sleeve 12 is loaded into the storage space formed by the cover plate 113 and the bottom plate 112 from the side where the short sealing plate 114 is located. The short sealing plate 114 needs to ensure that the guide sleeve 12 can enter and exit, and needs to axially limit the guide sleeve 12. Optionally, the cover plate 113 adopts an arched design, so that the side-center distance L of the entire drill supporting device is small, thereby reducing the over-excavation amount and saving construction costs, wherein the side-center distance L refers to the minimum distance from the center of the drill rod to the tunnel contour surface. Of course, in other embodiments of the utility model, the shape of the cover plate 113 can also adopt other shapes, such as rectangle, circle, etc. In addition, the end face profile of the short sealing plate 114 includes an outer circle and an inner circle, the center of the outer circle coincides with the center of the semicircle of the arch of the cover plate 113, the radius R1 of the outer circle is equal to the radius of the semicircle of the arch, and the center of the positioning hole on the guide sleeve 12 when the guide sleeve 12 falls on the bottom plate 112 after the limit plate 13 is withdrawn is used as the center of the inner circle, and the radius R2 of the inner circle is equal to the radius of the guide sleeve 12 plus the clearance margin, so as to ensure that the guide sleeve 12 can move in and out and the guide sleeve 12 can be axially limited. Among them, the clearance margin can be flexibly set according to the positioning accuracy requirements. Optionally, the bottom plate 112 is provided with a step 116 on the side close to the latch 15, which is used to hide the latch 15 and prevent the latch 15 from being exposed and scraped off by the tunnel surface, arch frame and anchor net, wherein the step 116 is formed by extending outward from the upper end surface of the bottom plate 112 to cover the protruding end of the limit rod 14. In addition, rib plates 117 are provided on the left and right sides of the cover plate 113 to improve the overall strength of the drill support 11 .

[0034] Optionally, the limiting plate 13 is designed in an L-shape, with the long side serving as a pad for the guide sleeve 12 to ensure that the guide sleeve 12 does not move up and down, and the short side serving to axially limit the guide sleeve 12 to prevent the guide sleeve 12 from slipping out, and the slot 131 is provided on the bottom surface of the long side. Preferably, after the limiting plate 13 is inserted into the drill bit support 11 and is padded under the guide sleeve 12, when the slot 131 is aligned with the first through hole 111, the short side of the limiting plate 13 just rests on the end surface of the guide sleeve 12. In addition, the long side of the limiting plate 13 is provided with a chamfer 132 to facilitate the insertion of the limiting plate 13. In addition, the short side of the limiting plate 13 is provided with an arc-shaped notch 133 to prevent interference between the connecting sleeve and the limiting plate 13 when the drill bit device is installed on the propulsion device.

[0035] In addition, another embodiment of the utility model further provides a rock drilling trolley propulsion device, preferably using the drill rod support device of the modular design as described above. It can be understood that the other components of the rock drilling trolley propulsion device of the utility model are the same as those of the existing rock drilling trolley propulsion device, and the only difference is the structure of the drill rod support device, so the positions and connection relationships of the other components are not repeated here.

[0036] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
