Technical Field

[0001] This application relates to the field of maintenance box technology, and in particular to a multi-functional maintenance box for locomotives. Background Technology

[0002] Locomotives, as the core power equipment of railway transportation, bear the heavy responsibility of pulling trains and transporting passengers and goods. They come in a variety of types. According to their use, there are passenger locomotives, freight locomotives, and shunting locomotives. When locomotives are under maintenance, appropriate maintenance boxes are needed to hold the tools used for maintenance.

[0003] Traditional locomotive maintenance boxes have a relatively simple function during use, serving only as tool containers and lacking integrated design. Therefore, maintenance personnel need to carry separate power tools such as electric screwdrivers and drills during maintenance, which increases their burden and makes them less convenient.

[0004] Therefore, in view of the problem that the traditional locomotive maintenance box has relatively simple functions and requires additional load, a multi-functional locomotive maintenance box can be designed. By integrating functions such as drilling and lighting into the maintenance box, the extra load on maintenance personnel can be reduced, thereby facilitating the solution of the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional locomotive maintenance boxes, which have relatively simple functions and are only used as tool containers, lacking integrated design, maintenance personnel need to carry separate power tools such as electric screwdrivers and drills during maintenance, which increases the burden on maintenance personnel and is not lightweight, this application provides a multi-functional locomotive maintenance box.

[0006] The technical solution is as follows: A multi-functional maintenance box for locomotives includes a box body, a box cover, a tool rack, a limiting rotating sleeve and a limiting rotating shaft. The box body has a tool compartment for storing tools, and the tool compartment has a tool rack for classifying tools. The top of the box body is fitted with a box cover for closing the tool compartment. A rotating groove is opened at one end of the bottom of the box body. A limiting rotating sleeve is provided at the top of the rotating groove. A limiting rotating shaft is provided inside the limiting rotating sleeve. The limiting rotating shaft rotates coaxially along the inside of the limiting rotating sleeve. The lower end of the limiting rotating shaft is provided with a connecting rotating sleeve for connecting screwdrivers or drill bits.

[0007] Furthermore, a motor compartment is provided on one side of the rotating slot, and a drive motor is provided inside the motor compartment. A transmission shaft is provided at the end of the drive motor near the connecting rotating sleeve, and a first-stage bevel gear is sleeved at the end of the transmission shaft away from the drive motor. A second-stage bevel gear corresponding to the first-stage bevel gear is sleeved at the outer end of the connecting rotating sleeve, and the first-stage bevel gear and the second-stage bevel gear are matched and meshed.

[0008] Furthermore, a battery compartment is located at the bottom center of the housing, and a battery pack is installed inside the battery compartment. Three sets of LED beads are arranged in a triangular shape at the outer end of the rotating slot. The drive motor, LED beads and battery pack are electrically connected.

[0009] Furthermore, the inner wall of the box cover is symmetrically arranged with multiple sets of elastic clips for fixing drill bits and screwdriver heads, and a sealing ring is fitted at the bottom edge of the box cover.

[0010] Furthermore, the tool rack has circular slots, rectangular slots, and closed slots inside for storing different maintenance parts, and the upper end of the closed slot is fitted with a movable cover plate.

[0011] Furthermore, a control panel is located at the front edge of the housing near the drive motor, and the control panel is electrically connected to the battery pack.

[0020] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-4 As shown, a multi-functional maintenance box for locomotives includes a box body 1, a box cover 2, a tool rack 3, a limiting rotating sleeve 24, and a limiting rotating shaft 25. The box body 1 has a tool compartment 101 for storing tools, and the tool compartment 101 has a tool rack 3 for classifying tools. The box body 1 has a box cover 2 for closing the tool compartment 101 at the upper end. The bottom end of the box body 1 has a rotating groove 18, and the top of the rotating groove 18 has a limiting rotating sleeve 24. The limiting rotating sleeve 24 has a limiting rotating shaft 25 inside, and the limiting rotating shaft 25 rotates coaxially along the inside of the limiting rotating sleeve 24. The lower end of the limiting rotating shaft 25 has a connecting rotating sleeve 19 for connecting screwdrivers or drill bits.

[0023] The inner wall of the cover 2 is symmetrically arranged with multiple sets of elastic clips 7 for fixing drill bits and screwdriver heads. A sealing ring 6 is fitted at the bottom edge of the cover 2. The sealing ring 6 significantly enhances the sealing performance of the box 1 and prevents dust, moisture and other impurities from entering the tool compartment 101.

[0024] The tool rack 3 has a circular slot 9, a rectangular slot 10 and a closed slot 11 for storing different maintenance parts. The upper end of the closed slot 11 is equipped with a movable cover plate 12. The circular slot 9, the rectangular slot 10 and the closed slot 11 can be used to classify and store maintenance parts according to their shape, making full use of the space in the tool compartment 101 and making the tools neat and orderly.

[0025] Multiple sets of connecting hinges 4 are provided between the rear ends of the box body 1 and the box cover 2. The box body 1 and the box cover 2 are movably connected by the connecting hinges 4. Three sets of female buckles 13 are evenly provided on the upper edge of the front end of the box body 1, and three sets of female buckles 8 are evenly provided on the lower edge of the front end of the box cover 2. The female buckles 13 and the female buckles 8 are matched and fastened. By matching and fastening the three sets of female buckles 13 and the three sets of female buckles 8, a reliable locking function can be provided when the box cover 2 is closed, ensuring that the box body 1 will not be accidentally opened during transportation and protecting the safety of the internal tools.

[0026] During operation, maintenance personnel first open the female latch 13 and the female latch 8, and then rotate the cover 2 through the multiple sets of connecting hinges 4 at the rear of the cover 2 and the body 1. Maintenance personnel can place various maintenance accessories in the corresponding slots according to the shape and type of the tools. For example, round parts such as gaskets and sleeves are placed in round slots 9; rectangular tools, such as flat pry bars and screwdriver handles, are placed in rectangular slots 10; and small, easily lost or specially protected accessories can be placed in closed slots 11. Then, the movable cover 12 is closed. At the same time, the elastic clips 7 symmetrically arranged on the inner wall of the cover 2 can be used to fix the drill bit and screwdriver head to prevent them from shaking inside the box. Finally, the cover 2 is closed and the female latch 13 and the female latch 8 are matched and engaged.

[0027] Its working principle is as follows: The slots of different shapes in the tool rack 3 are designed according to the shapes of common maintenance tools. Through this adaptability design, the space of the tool compartment 101 can be effectively utilized, making the tools more neatly placed. The movable cover 12 of the closed slot 11 is installed on the slot body by a simple hinge, which can be opened and closed flexibly to provide a closed storage space for special accessories. The elastic clips 7 on the inner wall of the box cover 2 are made of elastic materials, such as rubber or elastic plastic, and use the clamping force generated by its elastic deformation to fix the tools.

[0028] Beneficial effects: This tool storage design greatly improves the efficiency of tool classification and storage, allowing maintenance personnel to quickly find the tools they need, reducing the time spent searching through cluttered tools, improving the overall efficiency of maintenance work, and the orderly placement of tools also reduces collisions and wear between tools, extending the service life of the tools.

[0029] Example 2

[0030] Based on Example 1, such as Figure 1 , Figure 4 and Figure 5 As shown, a motor compartment 16 is provided on one side of the rotating slot 18. A drive motor 17 is provided inside the motor compartment 16. A drive shaft 21 is provided at the end of the drive motor 17 near the connecting sleeve 19. The end of the drive shaft 21 away from the drive motor 17 is fitted with a first-stage bevel gear 22. A second-stage bevel gear 23 corresponding to the first-stage bevel gear 22 is fitted at the outer end of the connecting sleeve 19. The first-stage bevel gear 22 and the second-stage bevel gear 23 mesh with each other. Through the transmission combination of the drive shaft 21, the first-stage bevel gear 22 and the second-stage bevel gear 23, the power of the drive motor 17 can be transmitted to the connecting sleeve 19 accurately and efficiently.

[0031] A battery compartment 14 is located at the bottom center of the housing 1. A battery pack 15 is installed inside the battery compartment 14. Three sets of LED beads 20 are arranged in a triangular shape at the outer end of the rotating slot 18. The drive motor 17, the LED beads 20 and the battery pack 15 are electrically connected. The three sets of LED beads 20 can provide sufficient and uniform lighting in dimly lit maintenance environments.

[0032] A control panel 5 is located at the front edge of the housing 1 near the drive motor 17. The control panel 5 is electrically connected to the battery pack 15. The start and stop of the drive motor 17 and the on and off of the LED beads 20 can be easily controlled through the control panel 5.

[0033] When performing locomotive maintenance in low-light environments, maintenance personnel can turn on the LED beads 20 through the control panel 5. The three sets of LED beads 20 arranged in a triangular pattern can provide sufficient and uniform lighting to illuminate the maintenance area.

[0034] When an electric screwdriver or drill bit is needed for operation, the maintenance personnel first insert the connecting handle of the drill bit and screwdriver into the connecting sleeve 19, and then start the drive motor 17 through the control panel 5. The drive motor 17 works, driving the transmission shaft 21 to rotate, which in turn causes the first-stage bevel gear 22 sleeved on the transmission shaft 21 to rotate. The first-stage bevel gear 22 meshes with the second-stage bevel gear 23 at the outer end of the connecting sleeve 19, transmitting power to the connecting sleeve 19. The connecting sleeve 19 drives the screwdriver or drill bit installed at its lower end to rotate, performing tightening or drilling operations. After the operation is completed, the drive motor 17 and LED light bead 20 are turned off, the tools are put back into the tool compartment 101, and the box cover 2 is fastened.

[0035] Its working principle is as follows: the control panel 5 is electrically connected to the battery pack 15, the drive motor 17, and the LED beads 20 to form a complete circuit control loop. When the corresponding switch on the control panel 5 is pressed, current flows out from the battery pack 15 to power the drive motor 17 and the LED beads 20. The drive motor 17, as a power source, converts electrical energy into mechanical energy. Through the transmission structure of the transmission shaft 21, the first-stage bevel gear 22, and the second-stage bevel gear 23, the direction of power transmission is changed, enabling the connecting rotating sleeve 19 to drive the tool to rotate. At the same time, during the rotation, the limiting rotating sleeve 24 plays a radial limiting role on the limiting rotating shaft 25, ensuring that the limiting rotating shaft 25 and the connecting rotating sleeve 19 can maintain a stable rotation state when driving the screwdriver or drill bit to work. The LED beads 20 convert electrical energy into light energy to realize the lighting function.

[0036] Its beneficial effects are significant. The multi-functional design of LED beads 20 and connecting adapter 19 greatly reduces the extra burden on maintenance personnel. They no longer need to carry power tools and lighting equipment separately. One maintenance box can meet a variety of work needs. During the maintenance process, the convenient operation of power tools improves work efficiency. Operations such as tightening screws or drilling are easier and faster. The good lighting effect improves the maintenance environment, enabling maintenance personnel to observe locomotive parts more clearly, reducing misoperation caused by insufficient light, and improving the accuracy and safety of maintenance work.
