Description

Technical Field

[0001] This utility model belongs to the field of dispatching and transportation vehicle technology, specifically a remote-controlled electric locomotive for coal mine dispatching. Background Technology

[0002] Underground coal mine dispatching and transportation environments are complex, space-constrained, and have extremely high safety requirements. Remote-controlled electric locomotives, as core dispatching equipment, are widely used in this field because they enable remote control by operators (forward, backward, speed adjustment, stopping, etc.), effectively ensuring personnel safety. These locomotives are generally equipped with special explosion-proof battery packs as a power source to meet the stringent explosion-proof regulations in underground operations. However, in current technical solutions, the battery pack is usually integrated into the locomotive body in a fixed installation manner, forming a relatively closed power unit.

[0003] This fixed battery integration design has several problems. Once the battery power is insufficient, the locomotive must be shut down and moved to a dedicated charging location or wait for charging equipment to arrive, requiring a lengthy charging process. This directly disrupts scheduling operations and severely limits the locomotive's ability to operate efficiently and continuously. Especially in scenarios with tight underground production schedules and extremely high requirements for the availability of transport equipment, the downtime caused by charging becomes a key bottleneck restricting production efficiency. Although a backup locomotive strategy is used in some situations, this significantly increases equipment purchase and maintenance costs and does not fundamentally solve the problem of single-unit operational interruptions.

[0004] In existing technologies, operators cannot efficiently disassemble depleted batteries and install fully charged batteries at the work site or in the vicinity. This structural deficiency inevitably leads to a "charging-waiting" cycle when the locomotive's battery is depleted, significantly reducing the actual utilization rate and operational continuity of the equipment, and further weakening its overall practicality in the flexible, efficient, and uninterrupted scheduling environment of underground coal mines. Therefore, there is an urgent need to develop a locomotive body that facilitates battery replacement, adapts to the harsh underground environment, and enables safe, rapid, and convenient replacement of battery packs, thereby improving equipment operating efficiency. Utility Model Content

[0005] To address the problem of prolonged work interruptions caused by battery depletion during underground coal mine operations, this invention provides a remote-controlled electric locomotive for coal mine dispatching that facilitates battery replacement.

[0006] This utility model is achieved through the following technical solution:

[0007] A remote-controlled electric locomotive for coal mine dispatching includes a locomotive body, a protective box with an opening on one side of the locomotive body, an installation slot communicating with the outside and capable of accommodating a battery body inside the protective box, a baffle for sealing the battery body slidably connected to the protective box, a connecting block on the side wall of the baffle, and a locking mechanism for locking the connecting block on the side wall of the protective box.

[0008] The mounting slot provides space for the battery body. After the connecting block on the operating baffle separates from the locking mechanism, the baffle unlocks the sealing of the mounting slot, thus enabling quick replacement of the battery body. Moreover, the battery body is placed on the upper part of the locomotive body, which facilitates the replacement operation, thereby greatly reducing the time spent on battery replacement and improving equipment operating efficiency.

[0009] A further improvement of this utility model is that the locking mechanism includes a fixed block, a guide rod, a compression return spring, and a movable block. The fixed block is fixedly installed on the protective box, and the guide rod passes through the fixed block. The movable block is connected to one end of the guide rod near the baffle. A compression return spring sleeved on the guide rod abuts against the movable block and the fixed block. Under the action of the compression return spring, the movable block abuts against the connecting block. By pushing the movable block and the guide rod towards the fixed block, the compression return spring is compressed and stored. At this time, the movable block and the connecting block on the baffle are in a separated and non-contact state. At this time, the baffle can be freely opened or closed on the protective box. After the battery body is replaced, the baffle is returned to the closed state, and the movable block returns to the state of abutting against the connecting block under the action of the compression return spring.

[0010] A further improvement of this invention is that the connecting block is provided with a slot, the slot being located on the side facing the connecting block, and the moving block is provided with a locking post that can cooperate with the slot. The slot on the connecting block and the locking post on the moving block engage in the locked state, which helps to improve the stability of the baffle in the blocked state.

[0011] A further improvement of this invention is that an elastic hose is sleeved around the compression return spring. This elastic hose provides protection to the outside of the compression return spring, preventing external impurities from contacting and corroding the spring, which could lead to a loss of elasticity.

[0012] A further improvement of this utility model is that a guide groove is provided on the side wall of the protective box. The guide groove is located on the same side as the locking mechanism, and the length direction of the guide groove is parallel to the axial direction of the guide rod. A guide block is slidably disposed in the guide groove, and the guide block is connected to the moving block. The guide block moves along the guide groove, thereby guiding the movement of the moving block.

[0013] A further improvement of this invention is that a toggle block is connected to the aforementioned movable block, which effectively enhances the ease of operation of the locking mechanism.

[0014] A further improvement of this utility model is that the opening of the protective box is provided with a second guide groove, the length direction of which is the same as the sliding direction of the baffle, and a second guide block connected to the baffle is slidably disposed within the second guide groove. The baffle forms a movement trajectory by moving along the second guide groove through the second guide block.

[0015] A further improvement of this invention is that the cross-section of the second guide groove is dovetail-shaped. This effectively ensures that when the locking mechanism and the connecting block are pressed together, the cooperation between the second guide groove and the second guide block allows the baffle and the protective box to form a locked state.

[0016] A further improvement of this utility model is that a shock-absorbing mechanism is provided between the aforementioned protective box and the locomotive body. The shock-absorbing mechanism includes a base, a buffer groove, a shock-absorbing rod, and a buffer spring. The base is fixedly installed on the locomotive body. Four buffer grooves are provided, each corresponding to one of the four corners of the protective box. The two ends of the shock-absorbing rod abut against the bottom of the buffer groove and the bottom surface of the protective box, respectively. The buffer spring is sleeved on the shock-absorbing rod. This shock-absorbing mechanism effectively counteracts vibrations during the operation of the locomotive body.

[0017] As can be seen from the above technical solution, the beneficial effects of this utility model are: the mounting slot provides a space for the battery body; after the connecting block on the operating baffle separates from the locking mechanism, the baffle unlocks the sealing of the mounting slot, thereby realizing the rapid replacement of the battery body; moreover, the battery body is placed on the upper part of the locomotive body, which facilitates the replacement operation, thereby greatly reducing the time consumed in the battery replacement operation and improving the operating efficiency of the equipment.

[0032] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0033] like Figures 1-8As shown, this utility model discloses a remote-controlled electric locomotive for coal mine dispatching, including a locomotive body 10. The locomotive body 10 is provided with a protective box 13 with an opening on one side. The protective box 13 is provided with an installation groove 14 that communicates with the outside and can accommodate a battery body 20. A baffle 30 for sealing the battery body 20 is slidably connected to the protective box 13. A connecting block 33 is provided on the side wall of the baffle 30. A locking mechanism 50 for locking the connecting block 33 is provided on the side wall of the protective box 13.

[0034] The mounting slot 14 provides space for the battery body 20. After the connecting block 33 on the operating baffle 30 is separated from the locking mechanism 50, the baffle 30 is unlocked from blocking the mounting port of the mounting slot 14, thereby enabling the rapid replacement of the battery body 20. Moreover, the battery body 20 is placed on the upper part of the locomotive body 10, which facilitates the replacement operation, thereby greatly reducing the time consumed in the battery replacement operation and improving the operating efficiency of the equipment.

[0035] The locking mechanism 50 includes a fixed block 51, a guide rod 52, a compression return spring 53, and a movable block 55. The fixed block 51 is fixedly installed on the protective box 13, and the guide rod 52 passes through the fixed block 51. The movable block 55 is connected to one end of the guide rod 52 near the baffle 30. The compression return spring 53, which is sleeved on the guide rod 52, abuts against the movable block 55 and the fixed block 51. Under the action of the compression return spring 53, the movable block 55 abuts against the connecting block 33. By pushing the movable block 55 and the guide rod 52 towards the fixed block 51, the compression return spring 53 is compressed and stored. At this time, the movable block 55 and the connecting block 33 on the baffle 30 are in a separated and non-contact state. At this time, the baffle 30 can be freely opened or closed on the protective box 13. After the battery body 20 is replaced, the baffle 30 is returned to the closed state, and the movable block 55 returns to the state of abutting against the connecting block 33 under the action of the compression return spring 53.

[0036] A guide groove 131 is provided on the side wall of the protective box 13. The guide groove 131 is located on the same side as the locking mechanism 50, and the length direction of the guide groove 131 is parallel to the axial direction of the guide rod 52. A guide block 132 is slidably disposed in the guide groove 131, and the guide block 132 is connected to the moving block 55. The guide block 132 moves along the guide groove 131, thereby guiding the movement of the moving block 55.

[0037] The connecting block 33 is provided with a slot 331, which is located on the side facing the connecting block 33. The moving block 55 is provided with a locking post 551 that can cooperate with the slot 331. The slot 331 on the connecting block 33 and the locking post 551 on the moving block 55 cooperate in the locked state, which helps to improve the stability of the baffle 30 in the blocked state.

[0038] A toggle block 56 is connected to the movable block 55, which effectively improves the ease of operation of the locking mechanism 50.

[0039] The compression return spring 53 is covered with an elastic hose 54. The elastic hose 54 forms a protective barrier on the outside of the compression return spring 53, preventing external impurities from contacting and corroding the compression return spring 53, which could lead to the failure of its elastic force.

[0040] The protective box 13 has a guide groove 31 at its opening. The length direction of the guide groove 31 is the same as the sliding direction of the baffle 30. A guide block 32 connected to the baffle 30 slides within the guide groove 31. The baffle 30 moves along the guide groove 31 via the guide block 32, forming a movement trajectory. The cross-section of the guide groove 31 is dovetail-shaped. Effectively, when the locking mechanism 50 and the connecting block 33 are pressed together, the cooperation of the guide groove 31 and the guide block 32 ensures that the baffle 30 and the protective box 13 are locked together.

[0041] The baffle 30 has an opening facing the same direction as its movement during the sealing operation in the shape of an inverted U-shape. This structure facilitates easy viewing of the status of the battery body 20 within the mounting slot 14.

[0042] The battery body 20 can also be stored in the battery tray to improve the ease of pulling out. When the battery tray is provided, the battery tray is provided with a handle 21 located at the opening of the baffle 30.

[0043] A shock-absorbing mechanism 40 is provided between the protective box 13 and the locomotive body 10. The shock-absorbing mechanism 40 includes a base 11, a buffer groove 41, a shock-absorbing rod 43, and a buffer spring 42. The base 11 is fixedly installed on the locomotive body 10. There are four buffer grooves 41, which correspond to the four corners of the protective box 13. The two ends of the shock-absorbing rod 43 abut against the bottom of the buffer groove 41 and the bottom surface of the protective box 13, respectively. The buffer spring 42 is sleeved on the shock-absorbing rod 43. The shock-absorbing mechanism 40 effectively counteracts the vibration during the operation of the locomotive body 10.

[0044] The shock absorber rod 43 integrates the functions of a telescopic rod and a shock absorber, and the buffer spring 42 is sleeved on the telescopic rod part.

[0045] The locomotive body 10 also includes a shock-absorbing plate 12, which is disposed between the base 11 and the protective box 13. The bottom surface of the shock-absorbing plate 12 is connected to the shock-absorbing rod 43, and a buffer gap is reserved between the shock-absorbing plate 12 and the base 11 under the support of the shock-absorbing rod 43. The protective box 13 can be installed on the shock-absorbing plate 12 by means of fasteners or welding. This buffer gap allows for a rough inspection of the shock-absorbing rod 43 and facilitates the installation of the protective box 13.

[0046] In summary, the operating principle of this device is as follows: when the battery body 20 is depleted, the operating toggle block 56 compresses the compression return spring 53. At this time, the locking pin 551 on the moving block 55 separates from the locking groove 331 on the connecting block 33. Subsequently, the baffle 30 is pulled outward. After the battery body 20 is replaced, the operating toggle block 56 maintains the compression return spring 53, slides the baffle 30 to the blocking state, and resets the compression return spring 53. The locking pin 551 engages with the locking groove 331, completing the locking state of the baffle 30. The electrical connection operation after the battery body 20 is replaced in this case is a conventional operation in the prior art, and therefore will not be described in detail.

[0047] The present invention relates to a remote-controlled electric locomotive for coal mine dispatching. The mounting slot provides space for the battery body. After the connecting block on the operating baffle separates from the locking mechanism, the baffle unlocks the sealing of the mounting slot, thereby enabling rapid replacement of the battery body. Moreover, the battery body is placed on the upper part of the locomotive body, which facilitates the replacement operation, thereby greatly reducing the time consumed in the battery replacement operation and improving the operating efficiency of the equipment.

[0048] 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.
