[0025] Embodiment 1
[0026] The embodiment of the present application provides a kind of operation platform lifting structure, as shown in Figures 1-6 It is shown that it includes sliding platform 1, which is provided with drill boom seat 11, vertically arranged mounting cavity 12 is formed in drill boom seat 11, the bottom of mounting cavity 12 is provided with linear mechanism 2, the movable end of which is vertically upwards, guiding column 13 is movably arranged in mounting cavity 12 along vertical direction, guiding column 13 is hollow inside and is provided with open bottom, the movable end of first linear mechanism 2 is extended into the inside of guiding column 13 through the bottom of guiding column 13 and is connected to the top surface of guiding column 13, the top of guiding column 13 is provided with connecting seat 19, and connecting seat 19 is connected to operation platform 3, which is used to carry operating personnel and install related control equipment.When sliding platform 1 is moved to predetermined construction position along slideway 4 and fixed, linear mechanism 2 drives guiding column 13 to rise, thereby driving operation platform 3 to rise, to obtain more open view. By the arrangement of mounting cavity 12 and guiding column 13, the inner cavity space of drill boom seat can be fully utilized, so that the lifting structure is more compact, thereby not affecting the spatial arrangement of other structures, and also enabling the size of the whole vehicle to be shortened as much as possible; when first linear mechanism 2 operates, the lifting of operation platform 3 can be guided by the cooperation of guiding column 13 and mounting cavity 12, so that the lifting stroke is more stable and reliable.
[0027] Preferably, as shown in Figure 2 Linear mechanism 2 is a hydraulic oil cylinder to improve the stability of the lifting of operation platform 3. In addition to hydraulic oil cylinder, linear mechanism 2 can also adopt linear air cylinder, linear electric cylinder, rack, pulley and other driving forms.
[0028] Specifically, as shown in Figure 2 and Figure 6As shown, the reinforcing rib plate 5 is arranged between the drill boom base 11 and the sliding platform 1, which can further improve the stability of the lifting stroke of the operating platform 3.
[0029] Specifically, as shown in the drawings, Figure 1 As shown, the drill boom base 11 is Y-shaped, and the vertical part is perpendicular to the sliding platform 1, and the mounting cavity 12 is arranged inside the middle of the drill boom base 11; the drill boom base 11 includes a first support plate 15 which is arranged perpendicular to the sliding platform 1, and the surface of the first support plate 15 is Y-shaped, and the first support plate 15 is provided with a vertical slot-shaped plate 16 on one side, and the two sides of the slot-shaped plate 16 are connected to the surface of the first support plate 15, and the slot-shaped plate 16, the first support plate 15 and the sliding platform 1 are used to form the mounting cavity 12; the drill boom base 11 further includes a second support plate 17 which is arranged on the sliding platform 1 and parallel to the first support plate 15, and the surface of the second support plate 17 is Y-shaped, and the slot-shaped plate 16 is located between the first support plate 15 and the second support plate 17, and the second support plate 17 is provided with a connecting plate 18 at the edge, and the connecting plate 18 is connected to the edge of the first support plate 15 and the outside of the slot-shaped plate 16 to form the drill boom base 11. The structure of the drill boom base 11 provides mounting space for the mounting cavity 12 and the guide column 13, and the structure layout is compact, and at the same time in the process of driving the operating platform 3 to lift by the linear mechanism 2, the drill boom base 11 can support the guide column 13 and the operating platform 3, further improving the lifting stability of the operating platform 3; the drill boom base 11 is used for mounting the drill boom, and the drill boom base is Y-shaped, which widens the connection width of the drill boom, thereby increasing the connection stability of the drill boom.
[0030] Specifically, as shown in the drawings, Figures 1-4As shown, the sliding platform 1 at the bottom of the mounting cavity 12 and the top surface of the guide column 13 are both provided with mounting seats 14. In this embodiment, a hydraulic cylinder is used as an example of the linear mechanism 2. The mounting seat 14 includes a pair of vertically arranged and parallel mounting plates 141. The sides of the two mounting plates 141 are vertically opened with mounting holes 142 whose axes coincide. The mounting shafts 143 are coaxially fitted in the two mounting holes 142 and fixed with pear-shaped pins 144. The axes of the mating shafts 143 at the bottom of the mounting cavity 12 and the mating shafts 143 on the top surface of the guide column 13 are both horizontal and perpendicular to each other. The lug at the bottom of the cylinder of the linear mechanism 2 is sleeved on the mating shaft 143 at the bottom of the mounting cavity 12, and the lug at one end of the piston rod of the linear mechanism 2 is sleeved on the mating shaft 143 on the top surface of the guide column 13. Correspondingly, an inspection door 121 can be opened at the bottom of the mounting cavity 12 to facilitate the disassembly, assembly, and maintenance of the linear mechanism 2. During installation, the linear mechanism 2 is first assembled with the guide post 13 via the mating shaft 143. Then, the guide post 13 and the linear mechanism 2 are fed into the mounting cavity 12. The lugs at the bottom of the cylinder of the linear mechanism 2 are aligned with the mounting holes 142 on the two mounting plates 141. The mating shaft 143 is then inserted and fixed with a pear-shaped pin 144. Disassembly is performed in the reverse order. By setting the two mounting shafts 143 horizontally and perpendicularly to each other, the linear mechanism 2 can be effectively fixed in a vertical position. At the same time, the mounting base 14 simplifies the installation and maintenance of the lifting structure and reduces the assembly difficulty and production cost of the drill arm base.
[0031] Example 2
[0032] This application provides a rock drilling rig, such as Figure 6 As shown, the rig's frame is equipped with a slide rail 4 arranged along its length. The rock drilling rig also includes an operating platform lifting structure as described in Embodiment 1. The sliding platform 1 is slidably fitted onto the slide rail 4. The surfaces of the first support plate 15 and the second support plate 17 are perpendicular to the length direction of the rock drilling rig. Both ends of the drill arm seat 11 are used to mount the drill arm. During tunnel construction, when the working position needs to be adjusted, the sliding platform 1 only needs to be moved along the slide rail 4, thereby moving the operating platform 3, the drill arm seat 11, and the drill arm mounted on the drill arm seat 11, thus adjusting the working position. Through the cooperation of the sliding platform 1 and the slide rail 4, the working range of the rock drilling rig is further expanded. Since the lifting structure not only effectively realizes the lifting of the operating platform 3 but also has a compact layout, it can effectively shorten the overall length of the rock drilling rig, giving it good passability and a wider field of vision, thereby improving the working quality and efficiency of the rock drilling rig.
[0033] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
