Description

Technical Field

[0001] This utility model relates to the field of rock drilling equipment technology, specifically a battery installation device for a single-arm computer trolley with a quick-change battery. Background Technology

[0002] In large-scale engineering operations such as mining and tunnel excavation, rock drilling rigs are the core crushing equipment. Single-arm computer-controlled rock drilling rigs are characterized by a single drill arm and a computer control system, representing a high degree of automation and intelligence. Within the rock drilling rig's operating system, the battery, as a core power supply component, directly impacts operational efficiency and maintenance costs due to its stable installation and ease of maintenance. Traditional rock drilling rigs often employ a fixed frame design for battery installation, housed inside the equipment. Maintenance personnel must extend their arms or even upper bodies inside the rig to operate the batteries, resulting in limited space, inconvenience, and increased safety risks from collisions and injuries. This severely restricts the efficiency and safety of battery maintenance operations.

[0003] To address the aforementioned technical issues, existing technologies have introduced pull-out battery mounting brackets. For example, Chinese utility model patent CN217881741U, by adding a base with a sliding rail and slidably connecting the battery-bearing bracket to the base rail, allows the bracket to be pulled out entirely from the base inside the trolley. This design effectively overcomes the limitations of traditional fixed installation methods, allowing maintenance personnel to operate on the battery on the pulled-out bracket without entering the trolley, significantly simplifying the disassembly and replacement process. However, in actual battery maintenance operations, besides needing to pull out the entire battery to expand the operating space, operations on the battery electrode surfaces are also crucial, such as the disassembly and connection of electrode wires, electrode cleaning, and electrode fault detection. While the sliding mounting bracket disclosed in the aforementioned patent allows for the complete pull-out of the bracket, it remains horizontally fixed after being pulled out, and the battery electrode surfaces remain vertical, making the disassembly and installation of the battery electrode wires inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies where the angle cannot be adjusted after the battery is pulled out, this invention provides a battery installation device for a single-arm computer trolley that allows for quick battery replacement. It adds a rotating column and rollers so that the battery electrode surface faces the operator after the battery is pulled out.

[0005] To achieve the above objectives, the specific solution adopted by this utility model is as follows: a battery installation device for a single-arm computer trolley with a quick-change battery, including a support frame and a connecting frame for placing the battery. The support frame includes two side plates and a bottom plate connecting the two side plates. Each side plate is provided with a slide rail, and both slide rails extend along the length of the side plate. The bottom plate is provided with a guide rail, which includes a guide portion arranged parallel to the slide rail and an inclined portion extending outward from the bottom plate, and the inclined portion is inclined downward. The connecting frame is rotatably connected between two slide rails via a connecting unit, and the bottom of the connecting frame is provided with rollers that can move along the guide rails. When the rollers move to the inclined part, the rollers are located between the connecting unit and the support frame.

[0006] As an optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: the side plate is provided with an installation groove for mounting a slide rail. The slide rail includes a support rail installed in the installation groove and a slide plate slidably connected to the support rail. The connecting frame is rotatably connected between the two slide plates through a connecting unit.

[0007] As another optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: the rotating unit is a cylindrical protrusion set at the bottom of the connecting frame and rotating columns set at both ends of the cylindrical protrusion, with the rotating columns and sliding plates rotatably connected in a one-to-one correspondence.

[0008] As another optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: the support rail is fixedly connected to a limit block, and a limit groove is opened on the sliding plate. The limit block and the limit groove slide together to limit the movement range of the sliding plate.

[0009] As another optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: a triangular block is provided in the support rail, and the sliding plate can be pressed tightly in the support rail by the triangular block during the movement of the support rail to fix the connecting frame.

[0010] As another optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: a top pressure block is provided at the end of the guide part away from the inclined part, and the roller can be pressed against the inner wall of the guide rail by the pressure block during the movement of the roller along the guide rail to fix the connecting frame.

[0011] As another optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: the lower end of the inclined part is provided with a limiting block for limiting the displacement of the roller.

[0012] As another optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: the connecting frame is configured as a frame structure adapted to the battery and open at the top, and a pressing component is provided at the opening, and the battery is fixed in the connecting frame by the pressing component.

[0013] As another optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: the pressing assembly includes an L-shaped plate, a locking stud, and a nut that is threadedly engaged with the locking stud. The L-shaped plate fits against one edge of the battery. One end of the locking stud is connected to the connecting frame, and the other end passes through the L-shaped plate and is fixed by the nut.

[0014] As another optimized solution for the battery installation device of the single-arm computer trolley with quick battery replacement mentioned above: a limiting plate is vertically fixed on the support frame, and a fixing plate parallel to the base plate is fixedly connected to the top of the limiting plate, with the connecting frame located on one side of the limiting plate.

Detailed Implementation

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a battery installation device for a single-arm computer trolley that allows for quick battery replacement. It includes a support frame 1 and a connecting frame 5. The connecting frame 5 houses the battery 6. The connecting frame 5 is slidably connected to the support frame 1 via two slide rails 3. The connecting frame 5 is rotatably connected between the two slide rails 3. When the connecting frame 5 is pulled out, that is, when the connecting frame 5 and the battery 6 placed in the connecting frame 5 are removed, the battery 6 is tilted, which facilitates the operator to connect and clean the electrode surfaces of the battery 6.

[0019] The support frame 1 is welded from steel plates. It includes two vertically arranged side plates 101 and a bottom plate 102 that connects the two side plates 101 and is horizontally arranged at the bottom of the side plates 101. Together, they form a U-shaped frame. The inner side of the two side plates 101 is provided with mounting grooves 2 along the length of the side plates 101. The slide rail 3 is fixed in the mounting grooves 2 by fastening screws.

[0020] The slide rail 3 consists of a support rail 301 and a sliding plate 304. The support rail 301 is fixed in the mounting groove 2 by fastening screws, and the sliding plate 304 can slide within the support rail 301. A limit block 302 is provided near the outer end of the support rail 301, and a limit groove 303 is provided on the sliding plate 304. The limit block 302 and the limit groove 303 slide in cooperation to limit the pulling stroke of the sliding plate 304.

[0021] The connecting frame 5 is used to support the battery 6. It is set as a rectangular frame with an opening at the top that is adapted to the shape of the battery 6. The bottom of the connecting frame 5 is provided with a cylindrical protrusion 12. The two ends of the cylindrical protrusion 12 are provided with cylindrical rotating posts 4. The sliding plate 304 corresponding to the position of the rotating post 4 is fixed with a bearing. The rotating post 4 is inserted into the inner ring of the bearing, thereby realizing a rotatable connection, so that the connecting frame 5 can rotate around the axis of the rotating post 4. The operator can use the cylindrical protrusion 12 as a handle when pulling out the connecting frame 5. The connecting frame 5 can be easily pulled out from the support frame 1 by using the handle. On the inner side of the connecting frame 5, i.e., the side furthest from the operator, a roller 10 is installed at its bottom. A guide rail 8 is provided on the base plate 102 of the support frame 1. The guide rail 8 has a groove-shaped structure and includes a guide section 801 parallel to the slide rail 3, located on the base plate 102, and an inclined section 802 extending outward from the base plate 102 and tilting downward. The roller 10 matches the guide rail 8, allowing the roller 10 to move within the guide rail 8. When the connecting frame 5 is pulled out, the roller 10 rolls from the guide section 801 to the inclined section 802. Because the trajectory of the inclined section 802 is tilted downward, the side of the connecting frame 5 where the roller 10 is located drops accordingly. The entire connecting frame 5 then rotates around the rotating column 4, changing from a horizontal state to an inclined state, so that the electrode surface of the battery 6 faces the operator, greatly facilitating wiring and maintenance operations.

[0022] A limiting block 11 is fixed at the lower end of the inclined part 802. The limiting block 11 is a protrusion with the same width as the guide rail 8, which is used to prevent the roller 10 from falling off the guide rail 8, so that the connecting frame 5 is safer and more stable during the pulling process.

[0023] like Figure 2 , Figure 5 As shown, triangular blocks 305 are provided at the inner ends of the two support rails 301. The triangular blocks 305 are made of rubber material and have a wedge-shaped structure. When the sliding plate 304 slides in the support rail 301, the triangular blocks 305 can elastically press the sliding plate 304 to fix it in the support rail 301. At the same time, due to the characteristics of the rubber material, it can buffer some of the vibration generated when the equipment is working.

[0024] like Figure 1 , Figure 6 As shown, a top pressure block 9 is fixed at the starting end of the guide section 801 of the guide rail 8. The structure of the top pressure block 9 is similar to that of the triangular block 305. The top pressure block 9 is also made of rubber. When the roller 10 moves in the guide rail 8, the top pressure block 9 can elastically press the roller 10, which plays the role of fixing and buffering vibration.

[0025] like Figure 7As shown, when the connecting frame 5 is retracted, the triangular block 305 presses against the sliding plate 304, and the pressing block 9 presses against the roller 10, which can initially fix the connecting frame 5. Then, the connecting frame 5 is fixed in the support frame 1 by a common mechanical locking mechanism. The locking mechanism in this embodiment adopts the relevant structure in the Chinese utility model patent with authorization announcement number CN217881741U. Specifically, a positioning plate 14 is horizontally fixed on the bottom plate 102 near the side plate 101. The positioning plate 14 has a positioning hole 1401. A pin 13 that can move up and down is provided on the connecting frame 5. When the connecting frame 5 is retracted, the pin 13 is inserted into the positioning hole 1401 on the positioning plate 14, thereby fixing the connecting frame 5.

[0026] A limiting plate 103 is provided on the side of the support frame 1 near the retracted connecting frame 5. The limiting plate 103 connects the two side plates 101 and is perpendicular to the bottom plate 102. The limiting plate 103 is used to limit the movement limit of the support frame 5. The upper part of the limiting plate 103 is bent to form a fixing plate 104. The fixing plate 104 is parallel to the bottom plate 102. The support frame 1 is fixed inside the body of the rock drilling rig through the fixing plate 104.

[0027] To fix the battery 6 inside the connecting frame 5, a pressing assembly 7 is provided at the opening of the connecting frame 5. The pressing assembly 7 includes an L-shaped plate 701 with an L-shaped cross-section, a locking stud 703, and a nut 702. The two pressure plates of the L-shaped plate 701 are in contact with the two outer surfaces adjacent to the top edge of the battery 6. One end of the locking stud 703 is rotatably connected to the side wall of the connecting frame 5, and the other end passes through the connection between the two pressure plates of the L-shaped plate 701. The free end of the locking stud 703 is threadedly engaged with the nut 702. The nut 702 can be a wing nut from existing commercial products. It can be tightened by hand without the need for wrenches or other tools. By tightening the nut 702, the L-shaped plate 701 can be pushed to press the top edge of the battery 6, thereby limiting and fixing it.

[0028] When the battery 6 needs to be replaced or repaired, the operator first pulls out the pin 13, and then pulls out the connecting bracket 5. The connecting bracket 5 moves outward along the support rail 301 via the sliding plate 304. At the same time, the bottom roller 10 rolls from the guide part 801 to the inclined part 802 within the guide rail 8. After the roller 10 enters the inclined part 802, the connecting bracket 5 rotates around the rotating column 4 under the action of gravity, making it tilted. This allows the electrode surface of the battery 6 to tilt upward, so that the operator can perform wiring, testing, and other operations without bending over or turning to the side, greatly reducing work fatigue. After the operation is completed, the connecting bracket 5 is pushed back inward, allowing the pin 13 to be reinserted into the positioning hole 1401.

[0029] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
