Description

Technical Field

[0001] This utility model belongs to the technical field of coal feeding vehicle equipment, and in particular relates to a coal feeding vehicle rail clamp. Background Technology

[0002] Coal feeding cars are key equipment used for transporting coal in industries such as coking, power generation, and metallurgy, and are typically moved and positioned via rails. During actual operation, coal feeding cars need to stop at specific locations for loading and unloading operations; therefore, they must have reliable rail-locking and positioning functions to prevent accidental slippage that could lead to safety accidents or operational errors. Traditional rail-locking devices often use manual pins, friction brakes, or simple mechanical blocks for fixation, which suffer from inconvenient operation, unreliable locking, and low automation. Especially in high-temperature, dusty industrial environments, manual operation is not only inefficient but also poses certain safety risks. Furthermore, common rail-locking structures often lack effective integration with pulley transmission mechanisms, making them prone to displacement due to vibration or track slope. Therefore, there is an urgent need for a coal feeding car rail-locking device that is structurally sound, easy to operate, provides stable locking, and is suitable for automated control.

[0025] Please see Figure 1-3 To achieve the above objectives, this embodiment provides a coal feeding car rail clamp, including a coal feeding car body 1 and a coal feeding track 2.

[0026] In this embodiment, the coal loading vehicle 1 is a mobile container for loading coal, and its bottom is connected to the coal loading track 2 via pulleys 3 to achieve sliding transportation along the track.

[0027] In this embodiment, the coal feeding track 2 is a fixed track system, usually made of metal, and its surface must meet the requirement of smooth movement of the pulley 3.

[0028] In this embodiment, the mounting base 4 is fixed to the side wall of the coal feeding car body 1, and a groove is provided at its bottom to accommodate the pulley 3 and allow it to move within a certain range.

[0029] In this embodiment, the rail clamping mechanism 5 is installed inside the mounting base 4, including: the lifting plate 6 is controlled to lift vertically by the driving component 7; the fixing rod 8 is fixed to the side wall of the lifting plate 6, and the end is provided with a protruding structure; the driving component 7 adopts a combination of motor and lead screw to drive the lifting plate 6 to move.

[0030] In this embodiment, a gear is embedded inside the pulley 3, which meshes or jams with the protrusion at the end of the fixing rod 8.

[0031] In this embodiment, the hook is located on the outer side wall of the coal feeding car body 1 and is used for hoisting or fixing auxiliary equipment.

[0032] In this embodiment, the coal loading car cover 10 covers the top opening of the car body and is sealed to the car body through the bottom locking frame. The top is provided with an observation window and a handle block for easy operation and monitoring.

[0033] In this embodiment, the limiting block 11 is fixed on the coal feeding track 2, and the side wall has a limiting groove to limit the displacement range of the pulley 3 and prevent derailment.

[0034] In this embodiment, the pulley 3 and the track undertake the function of moving the vehicle body, realizing the guidance and sliding of coal transportation.

[0035] In this embodiment, the pulley 3 is mechanically locked by the engagement of the protrusion with the inner gear of the pulley 3, preventing it from rolling, thereby fixing the vehicle body on the track.

[0036] In this embodiment, the drive unit 7 provides precise lifting control to ensure reliable engagement / disengagement of the protrusion and gear.

[0040] In this embodiment, the track limiting block 11 assists in positioning the pulley 3, thereby enhancing system safety.

[0041] Working principle

[0042] Normal operating condition: When the drive motor is not started, the lifting plate 6 is in the low position, the protrusion of the fixed rod 8 is separated from the gear of the pulley 3, the pulley 3 can roll freely, and the car body moves along the track.

[0043] Rail locking process: When it is necessary to fix the car body, the drive motor starts and pushes the sliding block 9 and the lifting plate 6 upward through the lead screw transmission;

[0044] The protrusion at the end of the fixed rod 8 rises and engages with the gear teeth inside the pulley 3, forming a mechanical mesh;

[0045] The gears were forcibly locked, pulley 3 could not rotate, and the car body was firmly fixed to the track.

[0046] Unlocking and recovery process: The drive motor reverses, the lead screw drives the lifting plate 6 to move down, the protrusion separates from the gear, and the engagement is released; the pulley 3 resumes free rolling, and the vehicle body can continue to move.

[0047] Auxiliary function coordination: The limiting block 11 constrains the lateral displacement of the pulley 3 through the limiting groove to prevent deviation when stuck on the rail; the sealing design of the cover ensures that the coal does not leak during transportation, and the observation window facilitates real-time monitoring. The above description is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the utility model concept and utilizing the content of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
