[0036] Example 1

[0037] like Figure 1 , Figure 2 The figure shows a double boom support device disclosed in the present embodiment, including a base frame, with boom mounting plates 1 provided at both ends of the base frame, and a boom mounting structure 101 on the front of the boom mounting plate 1, specifically a plurality of mounting holes provided on the boom mounting plate 1, for mounting the boom on the boom mounting plate 1. A sunken groove 2 is provided at the top of the base frame corresponding to the position between the two boom mounting plates 1, and the groove 2 passes through the base frame along the horizontal width direction of the base frame, that is, the base frame and the boom mounting plate 1 form a concave structure as a whole, thereby reducing the weight of the double boom support device while making the double boom support device have a higher structural strength. Among them, a through hole 3 that passes through the base frame vertically is provided at the bottom of the groove 2, so as to facilitate the passage of the hydraulic pipe, so that the double boom support device has good hydraulic pipeline passability, thereby effectively improving the space utilization rate of the rock drilling rig.

[0038] In this embodiment, the base frame includes a base and support mechanisms disposed at two ends of the top of the base, and both the base and the support mechanisms are box structures.

[0039] The base includes a bottom plate 4, a flat plate 5, a front sealing plate 6 and a rear sealing plate 7. The front sealing plate 6 and the rear sealing plate 7 are connected to the bottom plate 4 at intervals along the width direction of the base frame. The flat plate 5 is located above the bottom plate 4, and the flat plate 5 is connected to the front sealing plate 6 and the rear sealing plate 7 respectively. Among them, the top of the rear sealing plate 7 is higher than the top of the front sealing plate 6 and the flat plate 5, that is, the bottom surface of the flat plate 5 is connected to the top of the front sealing plate 6, and the rear end of the flat plate 5 is connected to the end surface of the rear sealing plate 7, and the through hole 3 is provided on the bottom plate 4 and the flat plate 5. The overall length of the flat plate 5 is shorter than the bottom plate 4, that is, after the flat plate 5 is connected to the front sealing plate 6 and the rear sealing plate 7, there is a gap between the left end of the flat plate 5 and the left end of the bottom plate 4, and there is also a gap between the right end of the flat plate 5 and the right end of the bottom plate 4, and the two supporting mechanisms fall symmetrically on the two gaps.

[0040] The support mechanism includes a first connecting plate 8, a second connecting plate 9 and a rib plate assembly. The bottom of the arm mounting plate 1 is connected to the end of the flat plate 5 and falls on the front sealing plate 6. The first end of the first connecting plate 8 is connected to the back of the arm mounting plate 1, the first end of the second connecting plate 9 is connected to the second end of the first connecting plate 8, and the second end of the second connecting plate 9 is connected to the top of the rear sealing plate 7. The rib plate assembly is connected between the first connecting plate 8, the second connecting plate 9 and the arm mounting plate 1. Specifically, the rib plate assembly includes a first rib plate 10 and a second rib plate 11 arranged at intervals, and the first rib plate 10 is closer to the groove 2, that is, the first rib plate 10 is located on the inner side of the second rib plate 11. The first rib plate 10 is respectively connected to the first connecting plate 8, the second connecting plate 9, the arm mounting plate 1, and the flat plate 5, and the second rib plate 11 is respectively connected to the first connecting plate 8, the second connecting plate 9, the arm mounting plate 1, and the bottom plate 4, so as to enclose the support mechanism into a box structure and connect the internal space of the base with the internal space of the two support mechanisms.

[0041] As a preferred embodiment, the two first connecting plates 8, the two second connecting plates 9 and the rear sealing plate 7 are integrally formed bent plates to reduce the assembly process of the double-arm support device, improve the manufacturing efficiency of the double-arm support device, and reduce the manufacturing cost.

[0042] As a preferred embodiment, the first rib plate 10 is an arc-shaped plate or a bent plate that is recessed in the direction away from the groove 2, so that the two inner side walls of the groove 2 expand outward, increasing the cross-sectional area of ​​the groove 2 and further improving the space utilization of the rock drilling trolley.

[0043] It is worth noting that the specific implementation of the base and the support mechanism in the specific application process is not limited to the structure shown in the figure, and other implementations can also be adopted, as long as the groove 2 and the through hole 3 are maintained. For example, a rectangular box composed of welded plates can be directly used as the base, and then the arm mounting plate 1 can be directly welded to the top of the base and reinforced by a rib plate. The rear sealing plate 7 can also be set lower than the flat plate 5, that is, the bottom surface of the flat plate 5 is connected to the top of the rear sealing plate 7, and the second end of the second connecting plate 9 is connected to the top surface of the flat plate 5.

[0044] In the specific implementation process, a third rib plate 12 is provided between the front sealing plate 6 and the bottom plate 4, and the number of the third rib plates 12 is multiple and is spaced apart along the length direction of the bottom plate 4. And / or a fourth rib plate 13 is provided between the rear sealing plate 7 and the bottom plate 4, and the number of the fourth rib plates 13 is multiple and is spaced apart along the length direction of the bottom plate 4.

[0045] It is worth noting that, although the through hole 3 shown in the present embodiment is a rectangular hole, in a specific application process, the through hole 3 can also be set as a circular hole or other shapes.

[0046] Example 2

[0047] Based on the double-arm support device in Example 1, this embodiment discloses a rock drilling trolley, on which the double-arm support device in Example 1 is provided.

[0048] refer to Figure 3 The double boom support device is arranged at the head end of the drilling trolley 14, the boom mounting plate 1 faces the front of the drilling trolley 14, and the boom assembly 15 is mounted on the boom mounting plate 1. Since the boom mounting plate 1 is relatively low in the double boom support device, the position of the boom assembly 15 is also relatively low, thereby effectively lowering the center of gravity of the drilling trolley 14 and improving its stability.

[0049] As the position of the boom assembly 15 is lowered, in order to prevent the body of the drilling trolley 14 from interfering with the pitching movement of the boom assembly 15, in this embodiment, the front end of the drilling trolley 14 is provided with a slope structure 16 tilted downward and forward.

[0050] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
