[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0029] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation. Moreover, in addition to being used to indicate orientation or positional relationships, some of the above terms may also be used to express other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0030] like Figure 1 and Figure 2As shown, the present embodiment provides a folding guardrail for a rock drilling rig, including a vertical rotating rod 100, a horizontal rotating rod 200 and a conversion mechanism 300. The guardrail is installed on the roof cover. Specifically, the roof cover is located on the top of the rock drilling rig, similar to a rectangle, including two short sides and two long sides, the two short sides correspond to the head (cab position) and the tail of the rock drilling rig, and the two long sides correspond to the side positions of the rock drilling rig. Users can repair the engine post-processing on the roof cover, such as fragile devices such as sensors, etc. In some cases, the air bag filter of the air compressor can be replaced, the air filter and the one-way valve in the hydraulic oil tank can be repaired, etc. At the same time, the user also needs to observe the water level of the engine auxiliary water tank on the roof cover of the rock drilling rig. It is particularly important to ensure the safety of the user's operation through the guardrail.

[0031] like Figure 1 , Figure 2 As shown, the vertical rotating rod 100 is rotatably connected to the roof cover via the first hinge 110. The transverse rotating rod 200 is rotatably connected to the vertical rotating rod 100 via the second hinge 210. Specifically, in order to ensure the strength of the guardrail, the first hinge 110 and the second hinge 210 can be protrudingly arranged on the rotating rod to disperse the stress borne by the hinge shaft inside the hinge. It is worth noting that the "rotating rod" mentioned in this embodiment means "vertical rotating rod" and / or "transverse rotating rod".

[0032] like Figure 1 As shown, the conversion mechanism 300 includes a sleeve 310 and a limiting member, the limiting member is movably connected to the sleeve 310 to limit the movement of the sleeve 310, when the limiting member is released from the sleeve 310, the sleeve 310 is mounted on the first hinge 110 and the second hinge 210, and the vertical rotating rod 100 and the horizontal rotating rod 200 are fixed. Generally speaking, when the sleeve 310 is mounted on the first hinge 110 and the second hinge 210, the horizontal rotating rod 200 and the vertical rotating rod 100 are perpendicular to each other, forming a stable protective structure.

[0033] The rotation direction of the vertical rotating rod 100 and the horizontal rotating rod 200 is consistent with the length direction of the roof cover, that is, the axis of the hinge shaft inside the hinge part is perpendicular to the length of the roof cover. This structure is fully adapted to the structure of the rock drilling rig, and sufficient space is reserved in the middle of the roof cover, which does not interfere with other equipment on the roof cover. At the same time, it is convenient for users to operate the guardrail in the middle of the roof cover to perform structural changes, which is convenient for users to move. If the rotation direction of the vertical rotating rod 100 and the horizontal rotating rod 200 is consistent with the width direction of the roof cover, the vertical rotating rod 100 and the horizontal rotating rod 200 will tilt in the width direction of the roof cover when folded, occupying the top space of the roof cover, which is not conducive to the user's operation safety.

[0034] In this way, the rock drill in this embodiment can solve the vehicle height limit problem by folding during driving. After arriving at the mine, it can be quickly unfolded and folded to reduce safety hazards during disassembly and assembly. At the same time, the sleeve 310 is used to stably support the hinge point, and the support force of the guardrail is further enhanced.

[0035] Specifically, Figure 3 As shown, the limiting member is a locking pin 320, and the sleeve 310, the vertical rotating rod 100, and the horizontal rotating rod 200 are provided with pin holes correspondingly. When the folding guardrail does not need to be folded, the locking pin on the vertical rotating rod 100 passes through the sleeve 310 and its corresponding pin hole in sequence, and the locking pin on the horizontal rotating rod 200 passes through the sleeve 310 and its corresponding pin hole in sequence, and the sleeve 310 is at a certain distance from the hinge part at this time.

[0036] Rock drilling rigs are usually located in uneven mining areas. After the user puts the sleeve 310 on and covers the hinged part, the sleeve 310 may release the restriction on the hinged part under the action of other external forces, and the guardrail begins to fold and lose its protective force, posing a great safety hazard.

[0037] Therefore, as a preferred solution, the sleeve 310 and / or the rotating rod include or are connected to a limiting portion. When the sleeve 310 is sleeved on the hinge portion, the limiting portion fixes the relative position of the sleeve 310 and the hinge portion, that is, the sleeve 310 will not be displaced without user intervention, thereby further preventing the sleeve 310 from loosening.

[0038] Furthermore, the vertical rotating rod 100 is provided with another pin hole as a part of the limiting portion, which is used to accommodate the locking pin so as to fix it relative to the first hinge portion 110 .

[0039] Further, such as Figure 4 As shown, an end of the horizontal rotating rod 200 close to the vertical rotating rod 100 is provided with an external thread 220, and the external thread 220 is a part of the limiting part. When the sleeve 310 covers the second hinge part 210, it can be threadedly connected with the horizontal rotating rod 200. After the user unfolds the folding guardrail, even after the user slides the sleeve 310 to the second hinge part 210, the horizontal sleeve 310 is still easy to slide left and right, so it is particularly necessary to fix the sleeve 310. The limiting part does not use a locking pin to prevent the user from being scratched by the locking pin when holding the guardrail.

[0040] Specifically, the guardrail further includes a support member, and the vertical rotating rod 100 is connected to the roof cover through the support member, so that the guardrail and the roof cover are firmly connected. The support member can be used as a part of the vertical rotating rod 100.

[0041] As an expansion solution, the support member is provided with a supporting member, which serves as one kind or a part of the limiting portion. When the sleeve 310 is sleeved onto the first hinge portion 110, the supporting member can abut against the sleeve 310. When the limiting portion of the vertical rotating rod 100 is disengaged from the sleeve 310, the sleeve 310 slides down to the first hinge portion 110 due to gravity and abuts against the supporting member at the same time. The supporting member restricts the further downward movement of the sleeve 310, so that the sleeve 310 stably limits the first hinge portion 110.

[0042] Specifically, as Figure 3 shown, it further includes a reinforcing plate 410. The reinforcing plate 410 is connected to the surface where the support member is perpendicular to the car roof cover, enhancing the support strength of the support member. Further, the supporting member can be the reinforcing plate 410 to further simplify the structure.

[0043] Specifically, the support member further includes a connecting column 400. A connecting plate 420 is fixedly connected to the connecting column 400. The area of the connecting plate 420 is larger than the cross-section of the connecting column 400. The support member is connected to the car roof cover through the connecting plate 410 to further increase the connection stability between the guardrail and the car roof cover. More specifically, waist-shaped holes are provided on the connecting plate 420 to reserve a tolerance space for the installation of the guardrail.

[0044] Further, as Figure 1 、 Figure 2 shown, at least part of the rotating rod is provided with a connecting member 120, which is used to connect to the adjacent rotating rod after folding, so that the guardrail is relatively fixed and prevents the guardrail from shaking violently in the folded state. For example, the connecting member 120 is in a "U" shape. One end of it is rotatably connected to the vertical rotating rod 100, and the other end is inserted into the jack. When the vertical rotating rod 100 approaches the horizontal rotating rod 200 due to folding, the user can remove one end of the connecting member 120 from the jack and insert it into the jack of the adjacent horizontal rotating rod 200.

[0045] Among them, the guardrail includes two opposite protective parts, which are respectively located on the two long sides of the car roof cover. The two groups of protective parts are respectively composed of the vertical rotating rod 100 and the horizontal rotating rod 200, and an avoidance space is formed between the protective parts. The front end of the rock drill is respectively provided with a cab position, and a ladder is provided at the rear end for the user to climb onto the car roof cover. The front end and the rear end may not be provided with a guardrail to simplify the structure as much as possible. Specifically, as Figure 1 、 Figure 2 shown, a protective plate 130 can be provided on the outside of the protective part. The protective plate 130 extends along the length direction of the car roof cover and is used to further support the guardrail.

[0046] The following is a usage method of a folding guardrail for a rock drill in this embodiment:

[0047] When the user needs to unfold the guardrail, the user pulls the vertical rotating rod 100 and the horizontal rotating rod 200 to make them perpendicular to each other, and then pulls out the locking pin, which releases the restriction on the sleeve 310. The user puts the sleeve 310 of the vertical rotating rod 100 on and covers the first hinge 110, and then inserts the locking pin at the corresponding position to fix the sleeve 310 relative to the first hinge 110; the sleeve 310 on the horizontal rotating rod 200 is put on and covers the second hinge 210, and the sleeve 310 is threadedly connected to the horizontal rotating rod 200. Under the action of the sleeve 310, the relative positions of the vertical rotating rod 100, the horizontal rotating rod 200 and the roof cover are fixed, and the guardrail forms a solid protection.

[0048] When the user needs to fold the guardrail, the sleeve 310 is removed from the first hinge 110 and the second hinge 210 respectively and fixed by the lock pin 320. After the vertical rotating rod 100 and the horizontal rotating rod 200 are rotated to a certain position, the adjacent rotating rods are fixed to each other through the connecting member 120, so that the guardrail remains in the folded state.

[0049] In this application, the terms "installed", "set", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
