Therefore, an automatic lid-locking device has been designed to improve the working environment and increase work efficiency.

[0003] The description of an automatic rotating locking device for a tank lid on a tank truck (publication number CN212922887U) mentions that "its characteristic is that a tank lid is installed on the tank body, an electromagnetic rotating device is installed on one side of the tank lid, a reset switch is installed on the side of the upper electromagnetic device, an upper electromagnetic device is installed below the tank lid; a lower electromagnetic device is installed below the upper electromagnetic device, and the lower electromagnetic device is installed on the tank body; the battery is connected to a multi-function switch box through a circuit, the multi-function switch box is connected to a wireless receiver through a wire, and the other end of the wireless receiver is connected to the electromagnetic rotating device." However, the locking device in the prior art only locks one side of the turntable, which may result in excessive rotational impact and failure to stop the turntable, and the locking is not safe and secure. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a coke tank car turntable locking device is provided to solve the problem that existing locking devices only lock one side of the turntable, which may result in excessive rotational impact that fails to stop the turntable, and the locking is not safe and secure.

[0005] To achieve the above objectives, a coke tank car turntable locking device is provided, comprising a base and a right locking structure. A chassis is provided on the base, and a turntable is rotatably connected to the chassis. The outer ring surface of the turntable is provided with multiple sets of protrusions, and an upper mounting plate is fixed to the upper end of the turntable. A left locking structure is fixed to the left side of the base, and a right locking structure is fixed to the right side of the base. The left and right locking structures are symmetrical about the center line of the base, and an upper clamping structure is installed on the upper part of both the left and right locking structures.

[0006] Furthermore, the lower part of the right locking structure is provided with a lower fixing frame, one end of which is fixed to the outside of the base, and the upper end of which is fixed to the lower fixing plate. The front and rear ends of the upper end of the lower fixing plate are respectively fixed with a front connecting plate and a rear connecting plate.

[0007] Furthermore, a lead screw is rotatably connected between the middle of the front connecting plate and the rear connecting plate, and one end of the lead screw is installed at the front end of the motor, and the motor is fixed outside the rear connecting plate.

[0008] Furthermore, a guide rod is fixed between the lower parts of the front connecting plate and the rear connecting plate, and a movable sleeve is fitted on the guide rod. The middle part of the movable sleeve is movably connected to the lead screw, and an upper fixing block is fixed at the upper end of the movable sleeve.

[0009] Furthermore, an upper clamping structure is fixed to the front end of the upper fixing block, and side pressure plates are provided on both the left and right sides of the front side of the upper clamping structure, and a middle pressure block is fixed to the middle of the front side of the upper clamping structure.

[0010] Furthermore, the side pressure plate is clamped on the upper and lower parts of the outer ring surface of the turntable, and the middle pressure block is pressed against the protrusion on the outer ring surface of the turntable.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, rotating the motor clockwise around the lead screw causes the movable sleeve to move horizontally forward, while rotating the lead screw counterclockwise causes the movable sleeve to move backward, allowing for flexible movement of the movable sleeve's position. Similarly, rotating the motor clockwise around the lead screw on the left locking structure causes its movable sleeve to move backward, while rotating the lead screw counterclockwise causes its movable sleeve to move forward, thus allowing for flexible control of the upper clamping structures on the left and right locking structures to stably and firmly clamp outside the turntable.

[0013] 2. The lower part of the movable sleeve is fitted outside the two sets of guide rods, which serves to stabilize and orient the movement, making it more accurate and reliable.

[0014] 3. In this utility model, the side pressure plates on the left and right sides of the front side of the upper clamping structure can be clamped on the upper and lower parts of the outer ring surface of the turntable, and then the middle pressure block is used to stably press against the protrusion on the outer ring surface of the turntable to ensure that the turntable cannot rotate or move, thereby driving the coking tank car turntable to lock.

[0027] As a preferred embodiment, the lower part of the movable sleeve 30 is fitted outside the two sets of guide rods 36, which serves to stabilize and orient the movement, making it more accurate and reliable.

[0028] In this embodiment, the front end of the upper fixing block 38 is fixed with an upper clamping structure 4, and the left and right sides of the front side of the upper clamping structure 4 are provided with side pressure plates 40, and the middle part of the front side of the upper clamping structure 4 is fixed with a middle pressure block 41; the side pressure plates 40 are clamped on the upper and lower parts of the outer ring surface of the turntable 12, and the middle pressure block 41 is pressed against the protrusion 13 protruding from the outer ring surface of the turntable 12.

[0029] In a preferred embodiment, the side pressure plates 40 on the left and right sides of the front side of the upper clamping structure 4 in this utility model can be clamped on the upper and lower parts of the outer ring surface of the turntable 12 respectively. Then, the middle pressure block 41 is used to stably press against the protrusion 13 on the outer ring surface of the turntable 12 to ensure that the turntable 12 cannot rotate or move, thereby driving the coking tank car turntable to lock.

[0030] This invention effectively solves the problem that existing locking devices only lock one side of the turntable, which may cause excessive rotational impact and fail to stop the turntable, and the locking is not safe and secure. This invention applies double-sided tight clamps to both sides of the turntable to achieve the purpose of locking the turntable, making it faster and more convenient to use, and safe and stable.

[0031] The above embodiments are used to explain and illustrate the present utility model, and are not intended to limit the utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims should be included within the protection scope of the present utility model.
