[0002] In the current rock drill rig market, the cab is typically a one-piece design. Typically, either an open or closed cab is standard, with the other offered as an option and manufactured only when specifically requested.

[0003] For example, the standard configuration is an open cockpit. When a request for a closed cab is made, temporary production and disassembly and replacement are required. This model makes it difficult to respond quickly to demand and has the problem of large temporary capital constraints.

[0004] In addition, whether replacing an open cockpit with a closed cab or vice versa, a large number of parts need to be disassembled and assembled during the process, resulting in additional oil loss and waste of labor time, thereby increasing production costs and usage costs. Summary of the Invention

[0005] The purpose of the present invention is to provide an interchangeable installation structure for an open cab and a closed cab, so as to solve the technical problems of the current integrated cab design, high disassembly and replacement costs, and time-consuming process.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The utility model relates to an interchangeable installation structure of an open driving cabin and a closed driving cab, which adopts a layered combined assembly of an upper driving cab layer and a lower driving cab layer.

[0008] The lower layer of the cab includes a cab bottom assembly, inside which are arranged operating areas 1 and 2. The upper layer of the cab includes an open roof assembly and a sealed top cover assembly.

[0009] When an open cab configuration is adopted, the open roof assembly is detachably mounted on the upper end of the cab bottom assembly; when a closed cab configuration is adopted, the sealed top cover assembly is detachably mounted on the upper end of the cab bottom assembly.

[0010] As a further solution of the present invention, a walking area is further provided inside the cab bottom assembly, and the operating area 1 and the operating area 2 are connected through the walking area.

[0011] As a further solution of the present invention, first connecting sleeves for splicing with the upper layer of the cab are provided on both sides of the cab bottom assembly.

[0012] As a further solution of the present invention, the open roof assembly includes a roof, and insertion rods are provided at both ends of the bottom of the roof, and the lower ends of the insertion rods are height-adjustably inserted into the inside of the first connecting sleeve.

[0013] As a further solution of the present invention, an oil cylinder is provided inside the first connecting sleeve, and the lower end of the oil cylinder is hinged to the lower end inside the first connecting sleeve through a lower pin shaft. The upper end of the oil cylinder piston rod extends into the interior of the insertion rod and is hinged to the upper end inside the insertion rod through an upper pin shaft.

[0014] As a further solution of the present invention, a friction block is provided at the upper end of the first connecting sleeve through a bolt. The friction block extends into the interior of the first connecting sleeve and abuts against the insertion rod. The friction block and the surface of the insertion rod are in sliding contact.

[0015] As a preferred embodiment of the present invention, the sealed top cover assembly includes a top cover, a panel and a door panel. The panel is arranged at the bottom of the top cover, the upper end of the door panel is hinged to the panel by a first hinge, and the lower end of the door panel is hinged to the cab bottom assembly by a second hinge.

[0016] A first plug-in block is provided at the bottom of the enclosure, and an annular limit groove is provided on the surface of the first plug-in block. The lower end of the first plug-in block is inserted into the first connecting sleeve, and a first locking pin is threadedly installed on the outer wall of the first connecting sleeve. The end of the first locking pin close to the first plug-in block is against the annular limit groove.

[0017] As a further solution of the present invention, a second plug is provided at the bottom of the enclosure, and a second connecting sleeve is provided on the bottom assembly of the cab.

[0020] Compared with the prior art, the interchangeable installation structure of an open cockpit and a closed cab provided by the present invention has the following beneficial effects:

[0021] 1. Improved production efficiency and flexibility: Whether the standard closed cab or open cockpit is used, manufacturers only need to stock the upper optional parts. They can quickly combine and replace them according to different configuration requirements, avoiding the complex overall production process. Compared with the traditional model of temporary production and replacement of the entire cab, this shortens the production cycle, improves production efficiency, and enhances the company's flexibility in responding to market orders.

[0022] 2. Reduce costs: Only the upper optional parts are stocked, which reduces the capital occupied by spare parts inventory. At the same time, when changing the configuration, it does not involve the disassembly and installation of accessories such as the oil pipes on the drilling rig, avoiding additional oil loss and the risk of leakage caused by disassembly and installation of the oil pipes. It also reduces the loss of working hours and does not require a large amount of manpower for complex parts disassembly and installation. The goal of reducing costs in many aspects such as inventory costs, consumables costs and labor costs is achieved.

[0023] 3. Enhanced product applicability and user experience: The lower sections of the closed and open cabs are common, while the upper sections are equipped with a sealed top cover assembly and an open roof assembly, respectively. This meets the diverse needs of different operating environments, prevents falling rocks from above, ensures basic operator safety, provides operators with a comfortable working environment, and improves the user's operating experience and equipment applicability.

[0024] 4. Simplified installation and maintenance process: The layered combination assembly only has different structures on the upper layer, making the installation, interchange and maintenance of the cab easier. When performing configuration interchange or repair, you only need to focus on the operation of the upper part, without having to make changes to the complex area at the lower end, which reduces the difficulty and complexity of installation and maintenance and improves the interchange efficiency.

[0040] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention will be understood based on specific circumstances.

[0041] See also Figure 2 The open cockpit of embodiment 1 of the present invention is shown. Figure 5The enclosed cab of Example 2 of the present invention is shown, which utilizes a layered assembly of an upper cab layer and a lower cab layer. The open cab of Example 1 of the present invention specifically features an open roof assembly 2 detachably mounted on the upper end of a cab bottom assembly 1; the enclosed cab of Example 2 of the present invention specifically features a sealed top cover assembly 3 detachably mounted on the upper end of a cab bottom assembly 1.

[0042] See also Figure 1 As shown, the interior of the cab bottom assembly 1 is provided with an operating area 101, a second operating area 102, and a walking area 103 connecting the operating area 101 and the operating area 102. The provision of the walking area 103 facilitates the operator to switch between the operating area 101 and the operating area 102, improving the convenience and efficiency of operation. The operator can switch between different operating areas without leaving the cab bottom assembly 1.

[0043] The upper and lower layers of the cab are separated by a combination of upper and lower layers. As the cab bottom assembly 1 of the lower layer of the cab, the operating area 101 and the operating area 2 102 provide operating space for the operator.

[0044] The open roof assembly 2 is suitable for work environments that require a wide field of view and good ventilation; the sealed roof assembly 3 is suitable for work scenarios that require protection from harsh environments such as dust, rain, and noise. The removable installation allows for flexible replacement of the upper layer configuration according to actual needs.

[0045] See also Figure 1 As shown, first connecting sleeves 104 are provided on both sides of the cab floor assembly 1 for connection to the cab upper layer. As a key component connecting the cab floor assembly 1 with the open roof assembly 2 or sealed roof assembly 3 on the cab upper layer, first connecting sleeves 104 provide a stable connection structure for the cab upper layer. Through first connecting sleeves 104, the cab upper layer components can be accurately mounted on the cab floor assembly 1, ensuring accurate and stable installation.

[0046] See also Figure 3 As shown, the open roof assembly 2 includes a roof 201. Rods 202 are located on either side of the bottom of the roof 201. The lower ends of the rods 202 are height-adjustably inserted into the interior of the first connecting sleeve 104. The rods 202 cooperate with the first connecting sleeve 104 to connect the open roof assembly 2 to the cab floor assembly 1. This height-adjustable connection, a well-known technique, allows the height of the roof 201 to be adjusted to meet the needs of different work scenarios, providing a better view or adapting to different spatial requirements.

[0047] See also Figure 4As shown, an oil cylinder 203 is provided inside the first connecting sleeve 104, and the lower end of the oil cylinder 203 is hinged to the lower end inside the first connecting sleeve 104 through a lower pin shaft 2031. The upper end of the piston rod of the oil cylinder 203 extends into the interior of the insertion rod 202 and is hinged to the upper end inside the insertion rod 202 through an upper pin shaft 2032.

[0048] Cylinder 203 provides power for adjusting the height of rod 202. By controlling the extension and retraction of cylinder 203, the piston rod pushes or pulls rod 202, thereby adjusting the height of ceiling 201. The hinged connection between lower pin 2031 and upper pin 2032 ensures the flexibility of cylinder 203 during operation, allowing it to adapt to changes in the height of rod 202.

[0049] A friction block 204 is provided at the upper end of the first connecting sleeve 104 via a bolt. The friction block 204 extends into the first connecting sleeve 104 and abuts against the surface of the insertion rod 202 . The friction block 204 and the surface of the insertion rod 202 are in sliding contact.

[0050] The friction block 204 provides guidance and support during the up and down movement of the rod 202. When the rod 202 moves up and down under the action of the oil cylinder 203, the sliding contact between the friction block 204 and the rod 202 ensures the accurate movement direction of the rod 202, prevents the rod 202 from shaking or deflecting during movement, and improves the stability of the height adjustment of the ceiling 201.

[0051] See also Figure 6 、 7 As shown, the sealed top cover assembly 3 includes a top cover 301, a surrounding panel 302 and a door panel 303.

The lower end of the first plug block 3021 is inserted into the first connecting sleeve 104, and a first locking pin is threadedly installed on the outer wall of the first connecting sleeve 104, and the end of the first locking pin close to the first plug block 3021 is against the annular limiting groove.

[0052] The top cover 301, enclosure 302, and door panel 303 of the sealed top cover assembly 3 together form an enclosed space, providing protection for the operator. The first insert 3021 cooperates with the first connecting sleeve 104 to connect the sealed top cover assembly 3 to the cab floor assembly 1. An annular retaining groove and a first locking pin securely secure the first insert 3021 within the first connecting sleeve 104, preventing the sealed top cover assembly 3 from shaking or shifting during operation. The door panel 303 is hinged via first and second hinges, facilitating entry and exit of the enclosed cab.

[0053] A second plug block 3022 is provided at the bottom of the enclosure 302, and a second connecting sleeve 105 is provided on the cab bottom assembly 1. The lower end of the second plug block 3022 is inserted into the second connecting sleeve 105, and a second locking pin for fixing the second plug block 3022 in the second connecting sleeve 105 is threadedly installed on the second connecting sleeve 105.

[0054] The cooperation between the second insert block 3022 and the second connecting sleeve 105 further enhances the stability of the connection between the sealed roof assembly 3 and the cab floor assembly 1. The second locking pin securely secures the second insert block 3022 within the second connecting sleeve 105. Together with the first insert block 3021 and the first connecting sleeve 104, it ensures the stability and reliability of the sealed roof assembly 3 after installation.

[0055] A glass window 304 is installed on the enclosure 302 by bolts. The glass window 304 is configured as double-layer insulating glass glued to a thermally-insulated aluminum alloy frame, so that the enclosed cab has good heat insulation, sound insulation and thermal insulation properties, effectively blocking the entry of external heat, noise and dust, providing a comfortable working environment for the operator. At the same time, the glass window 304 also makes it convenient for the operator to observe the external working conditions and is convenient for replacement when damaged.
