[0040] In the existing rock drilling rigs, whether it is a normal boom or a folding boom, the boom mechanism is exposed to the outside. When the rock drilling rig moves on the construction site, due to the harsh working environment of the construction site, such as in a tunnel or near a mountain, the soil and sand in the tunnel and on the mountain can easily fall on the boom mechanism, causing damage to the boom mechanism. And when the rock drilling rig is not in use, the boom mechanism is exposed to the air and is easily eroded by wind and sun, resulting in a reduction in the service life of the boom mechanism.

[0041] In order to solve the technical problem that the existing boom mechanism is easily corroded by wind and sun, resulting in a reduced service life, the present application provides a drilling rig folding boom mechanism and a rock drilling trolley, wherein the drilling rig folding boom mechanism includes a box body, a folding boom assembly and a boom base, the folding boom assembly is arranged in the box body through the boom base, the top of the box body is provided with an boom entrance and exit, and a first switch door is provided at the boom entrance and exit; when the folding boom assembly is in a folded state, the folding boom assembly is located in the box body, and the first switch door can be closed at this time, so that the box body forms a protective shell for the folding boom assembly and the boom base, preventing the folding boom assembly and the boom base from being corroded by wind and sun, and protecting the folding boom assembly and the boom base from being hit by sand and gravel, thereby improving the service life of the folding boom assembly and the boom base; when drilling is required, the first switch door is opened, the folding boom assembly extends from the boom entrance and exit, so that the folding boom assembly is in an unfolded state, so that the folding boom assembly can perform drilling operations.

[0042] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0044] In the embodiments of this application, refer to Figure 1 Zhihe Figure 4 As shown, a first aspect of an embodiment of the present application provides a drilling rig folding boom mechanism, comprising a box body 100, a folding boom assembly 200 and a boom base 300, the boom base 300 being arranged in the box body 100, the folding boom assembly 200 being arranged on the boom base 300, and a boom entrance and exit 110 and a first switch door 400 for closing or opening the boom entrance and exit 110 are arranged on the top of the box body 100.

[0045] The folding arm assembly 200 has a folded state and an unfolded state. In the folded state, the folding arm assembly 200 outside the box body 100 enters the box body 100 through the arm entrance and exit 110, and the first switch door 400 closes the arm entrance and exit 110; in the unfolded state, the first switch door 400 opens the arm entrance and exit 110, and the folding arm assembly 200 extends from the arm entrance and exit 110 to the outside of the box body 100.

[0046] In the drilling rig folding boom mechanism of the present application, the box 100 may be in the shape of a rectangular parallelepiped with a cavity therein, and a waterproof sunscreen layer may be provided on the outer surface of the box 100. A boom entrance 110 is provided on the top of the box 100, wherein the size of the boom entrance 110 is sufficient for the boom to be extended. In this embodiment, the size of the boom entrance 110 is the same as the top wall of the box 100, that is, the top of the entire box 100 is the boom entrance 110, and a first switch door 400 is provided at the boom entrance 110. When the first switch door 400 is opened, the boom entrance 110 is in an open state, and when the first switch door 400 is closed, the boom entrance 110 is in a closed state. When the size of the boom entrance 110 is the same as the top wall of the box 100, the first switch door 400 forms the top wall of the box 100, thereby ensuring that the boom entrance 110 is maximized, and facilitating the extension and folding of the folding boom assembly 200.

[0047] The boom base 300 is disposed in the box body 100 . In order to ensure the stability of the construction, the boom base 300 is disposed at the bottom surface of the box body 100 .

[0048] The folding arm assembly 200 is arranged on the arm base 300, and the folding arm assembly 200 can be folded and unfolded. When the folding arm assembly 200 is in the folded state, the folding arm assembly 200 is located in the box body 100. At this time, the first switch door 400 can be closed, so that the box body 100 forms a sealed box body 100, and the folding arm assembly 200 and the arm base 300 are located in the sealed box body 100. The box body 100 forms a protective shell for the folding arm assembly 200 and the arm base 300 to prevent the folding arm assembly 200 and the arm base 300 from being eroded by wind and sun, and protect the folding arm assembly 200 and the arm base 300 from being hit by sand and gravel, thereby improving the service life of the folding arm assembly 200 and the arm base 300, and solving the technical problem that the existing arm mechanism is easily eroded by wind and sun, resulting in a reduced service life.

[0049] And because the folding boom assembly 200 and the boom base 300 are arranged in the box 100, the storage, transfer and transportation of the present application are convenient, and only the box 100 needs to be transported. Compared with the existing boom mechanism, when transporting the boom mechanism, it is necessary to consider the space occupied by the boom mechanism and the force balance problem, and the transportation terrain requirements are higher. The drilling rig folding boom mechanism of the present application is more convenient during transfer and transportation because the folding boom assembly 200 and the boom base 300 are arranged in the box 100.

[0050] When drilling is required, the first switch door 400 is opened, and the folding arm assembly 200 can be extended from the arm entrance 110, so that the folding arm assembly 200 is in an unfolded state, so that the folding arm assembly 200 can perform drilling operations.

In this embodiment, the inspection port 120 is arranged on the rear side of the box body 100, that is, the rear end of the drilling trolley. And because the inspection port 120 is connected with the boom entrance 110, the boom entrance 110 is further expanded. When the first switch door 400 and the second switch door 500 are opened at the same time, the extension space of the folding boom assembly 200 is maximized, thereby expanding the extension space of the folding boom assembly 200.

One end of the second rod 2511 is hinged to the first arm 210, and the other end of the second rod 2511 is hinged to one end of the third rod 2512. The other end is hinged to the second arm 220, one end of the second pitch cylinder 252 is hinged on the first arm 210, and the other end of the second pitch cylinder 252 is hinged at the hinge of the second rod 2511 and the third rod 2512. When the second pitch cylinder 252 is extended and retracted, the second arm 220 can be folded and unfolded at the hinge of the second arm 220 and the first arm 210. It should be noted that this embodiment only proposes a specific structure of the second driving link mechanism 250, and other driving link mechanisms can realize the folding and unfolding of the second arm 220.

[0058] The third driving link mechanism 260 is used to drive the tail arm 230 to rotate at the hinge between the tail arm 230 and the second arm 220 to realize the folding and unfolding of the tail arm 230. The specific third driving link mechanism 260 includes a third pitch cylinder. One end of the tail arm 230 has two hinge points, and the two hinge points are distributed up and down. One end of the third pitch cylinder is hinged to the second arm 220, and the other end of the third pitch cylinder is hinged to a connection point of the tail arm 230. The other connection point of the tail arm 230 is hinged to the second arm 220. When the second pitch cylinder 252 is extended and retracted, the tail arm 230 can be folded and unfolded at the hinge between the tail arm 230 and the second arm 220. It should be noted that this embodiment only proposes a specific structure of the third driving link mechanism 260, and other driving link mechanisms can realize the folding and unfolding of the tail arm 230.
