[0038] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0039] The following is combined with Figure 1-13 This application is described in further detail.

[0040] An embodiment of the present application discloses a rock drill assembly line device.

[0041] Reference Figure 1A rock drill assembly line device includes a main base 10, an assembly trolley 20 and an assembly workbench 30. The main base 10 is used as a main working platform 11 to provide support. The main base 10 is used as a main working platform 11 to provide stable support and operation basis for the assembly process of the rock drill 02; multiple assembly workbenches 30 are arranged on the main base 10, and each assembly workbench 30 forms a workstation; the assembly trolley 20 is used to clamp the rock drill 02, and the assembly trolley 20 is slidably arranged on the main base 10 to drive the rock drill 02 to move between the assembly workbenches 30 along the assembly process; the assembly trolley 20 includes a turntable 23 and a support seat 22 arranged on the turntable 23, and the support seat 22 is used to clamp the main body of the rock drill 02. The turntable 23 drives the support seat 22 to rotate so that the main body of the rock drill 02 faces the corresponding assembly workbench 30 at different angles, so as to perform corresponding assembly operations at different workstations. The main base 10 provides a stable support and operating basis, and the assembly trolley 20 is slidably set on the main base 10 to guide the rock drill 02 body to move between the various workstations, and the support base 22 is driven by the turntable 23 to rotate and adjust the angle of the rock drill 02, and the corresponding component assembly is completed at each workstation; its working method is to fix the assembly trolley 20 at each workstation, and achieve efficient and accurate component assembly through the angle adjustment of the turntable 23, and finally transfer the finished product with the help of a sling and circulate the trolley through the consignment system 40. This design optimizes the assembly process, significantly improves the assembly efficiency, assembly quality and ease of operation, and effectively reduces the labor intensity of workers.

[0042] Reference Figure 2 The rock drill assembly line device also includes a consignment system 40 for circulating the assembly trolley 20. The consignment system 40 is arranged along the arrangement direction of the assembly workbench 30. The moving direction of the assembly trolley 20 on the consignment system 40 is opposite to the moving direction of the assembly trolley 20 on the main base 10, so that the assembly trolley 20 circulates. The consignment system 40 includes a bottom base 41, a trolley bracket 43 slidably arranged on the bottom base 41, a driving system 45 for driving the trolley bracket 43 to move, and a steel wire rope 44 connecting the driving system 45 and the trolley bracket 43. A flower basket buckle 42 is provided on the steel wire rope 44, and the flower basket buckle 42 is a bidirectional steel wire rope 44 tightening structure to prevent the steel wire rope 44 from loosening. The flower basket buckle 42 is a connecting device for adjusting the tightness of the wire rope 44, and is composed of a hollow screw and screw hooks at both ends. By rotating the hollow screw, the telescopic lengths of the screw hooks at both ends can be changed at the same time, thereby adjusting the tension of the connected wire rope 44 or chain to ensure that it is in a properly tightened state to prevent loosening or over-tightening. The working method of the flower basket buckle 42 is to connect the screws at both ends to the ring buckles of the wire rope 44 respectively, and then rotate the hollow screw to drive the internal thread to move, so that the wire rope 44 is gradually tightened or loosened.

[0043] The transport system 40 realizes the circulation of the assembly trolley 20 through the coordinated work of the base 41, the trolley bracket 43, the driving system 45, the wire rope 44 and the basket buckle 42, so as to improve the efficiency and continuity of the assembly line operation, reduce the labor intensity of manual handling, and ensure the flexibility of small batch production and the automation of the assembly process; its specific structure includes the base 41 as a supporting frame, carrying and guiding the trolley bracket 43 to slide, the trolley bracket 43 is used to carry the assembly trolley 20 back to the starting position, the driving system 45 pulls the bracket to slide along the base 41 through the wire rope 44, and the basket buckle 42 is used to adjust the The steel wire rope 44 is in a tensioned state to ensure smooth transportation; the working principle is that when the assembly trolley 20 completes the assembly of all workstations, the trolley is placed on the trolley bracket 43 of the consignment system 40 by the cantilever crane, and the drive system 45 is started, and the bracket is driven by the steel wire rope 44 to move along the bottom base 41 toward the starting workstation, and the moving direction is opposite to the running direction of the assembly trolley 20 on the main base 10, forming a circular flow. After the bracket arrives at the starting workstation, the trolley is hoisted back to the guide rail of the main base 10, ready for the next round of assembly operations, thereby realizing the efficient recycling of the assembly trolley 20, improving production efficiency, and optimizing the assembly line process.

[0044] Reference Figure 3 The main base 10 includes a platform 11, and a station support platform corresponding to the assembly workbench 30 is arranged along the length direction on one side of the platform 11. A guide rail for guiding the assembly trolley 20 is arranged along the length direction on the platform 11. Each support platform corresponds to an assembly station, which reduces interference between stations and clearly divides assembly tasks. The guide rails should be arranged along the length direction of the platform 11 and matched with the wheels 26 of the assembly trolley 20 to ensure that the trolley moves smoothly between the workstations. The material should be made of high-strength wear-resistant steel to ensure the bearing capacity and service life. The installation of the guide rails requires strict horizontal leveling to avoid the trolley from sliding smoothly due to unevenness. At the same time, it can be designed as a double-track structure to enhance the stability of movement; the width and depth of the guide rail grooves should be accurately processed according to the size of the trolley wheels 26, and anti-skid treatment should be added to the surface of the guide rails to prevent deviation during sliding. If necessary, a limit device or buffer device can be set at the end of the guide rail to prevent the trolley from sliding off the track or colliding; in addition, drainage troughs can be arranged on both sides of the guide rails to facilitate the cleaning of oil and debris generated during the assembly process, ensuring that the guide rails remain clean and run smoothly for a long time. The overall design meets the high precision and high efficiency requirements of the assembly line.

[0045] Reference Figure 3, a guide rail is provided on the platform 11 to guide the assembly trolley 20 to move smoothly between the workstations.

A latch seat 15 is provided on the platform 11 corresponding to the workstation support platform, and a latch that plugs into the latch seat 15 is provided on the assembly trolley 20. A latch seat 15 is also provided on the surface of the platform 11 to match the latch on the assembly trolley 20. The position of the trolley is fixed by the latch to prevent displacement during movement and ensure the stability and accuracy of assembly. The working method is as follows: the assembly trolley 20 is placed on the guide rail of the platform 11, and the worker pushes the trolley to slide along the guide rail to the target workstation. After the trolley arrives, it is positioned and fixed by inserting a pin into the pin seat 15 of the platform 11; after the trolley is in a fixed position, the workstation support platform provides stable support for the worker's operation, and cooperates with the workstation equipment such as the rotary worktable 32, the sling 33 and the pressing device 31 to complete the assembly work; after completing the task of one workstation, pull out the pin, and the trolley moves along the guide rail to the next workstation, and repeat the above operation; the entire process relies on the stable support of the platform 11 and the precise guidance of the guide rail, so that the assembly process is smooth and accurate, and the overall assembly efficiency and quality are improved.

[0046] Reference Figure 4 The platform 11 is provided with an oil drain hole, which is designed to be self-leveling with a slope so that the liquid on the platform 11 flows to the oil drain hole under the action of gravity, and a ball valve is connected to the bottom of the oil drain hole. The main base 10 includes the platform 11, which is the main working area, and its surface adopts a self-leveling design to facilitate the liquid such as lubricating oil to flow to the oil drain hole along the slope, and the oil drain hole is connected to a ball valve for cleaning.

[0047] Reference Figure 5 The assembly trolley 20 also includes a frame 21, the bottom of which is provided with wheels 26 for cooperating with the guide rails, a turntable 23 rotatably provided on the frame 21, and a support plate 24 for supporting the rock drill 02. The frame 21 structure in the assembly trolley 20 cooperates with the guide rails through the wheels 26 at the bottom, so that the trolley can slide smoothly and realize the smooth movement of the rock drill 02 between the workstations; a turntable 23 is provided on the frame 21, and the turntable 23 can be flexibly rotated on the frame 21, driving the support plate 24 to adjust the angle of the rock drill 02, so as to meet the assembly requirements of different workstations; the support plate 24 is used to firmly support the main body of the rock drill 02, and prevent the main body from being displaced during the movement or assembly process through a fixing device. The overall function of the structure is to provide the movement and support functions of the rock drill assembly, and at the same time, through the rotation adjustment of the turntable 23 and the sliding guide of the wheels 26, the assembly trolley 20 can accurately and flexibly complete the assembly process, effectively improving the assembly efficiency and the convenience of operation.

[0048] Reference Figure 6The assembly work platform 11 includes a press-fit device 31, a rotary work table 32 and a sling 33. A component assembly tool can be detachably installed on the rotary work table 32. The component assembly tool is used to assemble the component module. The sling 33 is installed on the component assembly tool to sling the component module on the rotary work table 32 to the press-fit device 31. The press-fit device 31 is used to press the component module onto the main body of the rock drill 02. The structural function of the assembly work platform 11 is to provide support for the efficient and precise assembly of rock drill components. Through the synergistic effect of the press-fit device 31, the rotary work table 32 and the sling 33, the assembly process is optimized, the labor intensity of workers is reduced and the assembly quality is improved; its specific detailed structure includes the press-fit device 31 used to apply standardized pressure to complete the precise assembly of components, avoiding errors and quality problems caused by traditional knocking operations; the rotary work table 32 supports horizontal rotation, and the component assembly tool can be detachably installed on it, which is used to fix and assemble various types of component modules, and the installation of parts in different directions is achieved through rotation, reducing handling and flipping; the sling 33 is installed On the component assembly tooling, it is used to lift the assembled parts module from the rotary workbench 32 to the pressing device 31, and accurately dock it with the main body of the rock drill 02; the working principle is that the component module is first installed on the rotary workbench 32 and the preliminary assembly is completed. The worker uses the tooling to fix the module and rotates the workbench as needed to complete multi-faceted operations; after the assembly is completed, the module is transferred to the pressing device 31 through the hoist 33, and the pressing device 31 is used to apply standardized pressure to complete the connection with the main body of the rock drill 02; this process ensures the efficiency, accuracy and standardization of the assembly, while reducing the labor intensity and assembly errors in manual operation.

[0049] Specifically, in order to facilitate the operation of the staff, a signboard 14 is set on the platform 11. The signboard 14 is the place where the process documents or drawings are placed. Magnets are used to clamp the documents, which is convenient for the workstation to check the drawings. The signboard 14 should be set in a conspicuous and easy-to-operate position on the platform 11 to avoid blocking the operator's line of sight or affecting the operation of the equipment. It is easy to move and adjust by using magnets. At the same time, it has a transparent protective layer to prevent document contamination, and a multifunctional clamp to ensure that the document is stable and does not fall off. The material of the signboard 14 is selected from lightweight and durable aluminum alloy or plastic, equipped with a partition design to display process documents, precautions and production progress, and an erasable area is added for marking temporary information.
