Description

Technical Field

[0001] The invention belongs to the technical field of anti-slipping, and relates to an off-vehicle automatic vehicle arrester device for a tank truck. Background Art

[0002] A wheeled tank truck is a special vehicle that is mainly used to transport bulk goods such as various liquids, liquefied gases and powdered goods. It is generally dangerous. The vehicle body is composed of a power unit, a tank body, safety devices, etc. It is suitable for use in many fields such as petroleum, chemical industry, food, medicine, agriculture, etc.

[0003] The working mode of the tank truck is to enter the loading area, locate and turn off the engine, manually operate the grounding safety device, anti-slip (car blocker) safety device, emergency stop filling safety device, etc., and manually operate the equipment to load the tank truck. The existing anti-slip (car blocker) safety device has the following problems during use:

[0004] 1. The position of the manually operated car blocker is not standard, or even the car blocker is not placed;

[0005] 2. After the vehicle is filled, if the vehicle blocker is not removed, the tank truck cannot leave the loading area, and even danger may occur;

[0006] 3. Due to different loading area environments, manual operators are at risk of corrosion, burns, etc. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a non-vehicle-mounted automatic car blocker device for a tank truck, which can automatically identify the car blocker placed behind the wheel and automatically remove it after the tank truck completes loading and unloading. It has a high degree of automation, improves efficiency, saves labor, and thus ensures the safety of the staff.

[0008] The technical solution adopted by the present invention is:

[0009] A non-vehicle-mounted automatic car blocker device for a tank truck comprises a ground rail, on which is mounted an outer shell box capable of moving along the ground rail, within which are mounted a wheel identification sensor capable of wheel identification, a three-axis mechanical arm for driving a car block triangle to move, and an electric control box, wherein the three axes of the three-axis mechanical arm and the outer shell box are connected to corresponding drive motors for driving the movement thereof, and the wheel identification sensor and the drive motor are connected to the electric control box; a car block triangle which is driven by the three-axis mechanical arm to move outward to a wheel block position or to be removed and retracted into the outer shell box is mounted at the free end of the three-axis mechanical arm.

[0010] Furthermore, the side of the outer shell box facing the tank truck is an open structure.

[0011] Furthermore, an alarm is installed on the outer casing, and the alarm is connected to the electric control box.

[0012] Furthermore, a junction box is provided on one side of the ground rail, and the outer casing is connected to the junction box via a chain cable, and the chain cable can move with the outer casing.

[0013] Furthermore, the bottom of the outer shell box is provided with running wheels that can move along the ground rails.

[0014] Furthermore, a stop wheel is provided at the bottom of the outer shell body on the outside of the running wheel, and the stop wheel is used to limit the running distance of the outer shell body on the track, that is, the running limit positions at both ends when walking left and right.

[0015] Furthermore, the three-axis robotic arm includes one axis, two axes, and three axes. The lower end of the one axis is connected to the first drive motor that drives it to rotate, the upper end of the one axis is fixedly connected to the second drive motor, the second drive motor is connected to the upper ends of the two axes driven to rotate thereby, the lower ends of the two axes are connected to the third drive motor, the third drive motor is connected to the three axes driven to rotate thereby, and the free ends of the three axes are fixedly connected to the anti-wheel triangle.

[0016] Furthermore, an auxiliary force rod is installed in the outer shell, the auxiliary force rod is cross-arranged with an axis, the lower end of the auxiliary force rod is hinged on the bottom surface of the outer shell, and the upper end of the auxiliary force rod is hinged with an axis through a connecting frame. The present invention supports an axis through the auxiliary force rod to ensure the reliability and stability of the movement of the three-axis mechanical arm.

[0017] Furthermore, the specific steps of placing the blocking triangle wood by the control system of the electric control box are as follows:

[0018] S11, when the tank truck enters the loading area, is positioned and turned off, the tank arrester is automatically / manually started;

[0019] S12, the wheel recognition sensor in the outer casing moves on the ground rail throughout its travel to locate the tank truck wheel. If it cannot be identified, an alarm is triggered and manual intervention is required. After the tank truck wheel is identified, step S3 is entered;

[0020] S13, move the second axis, the first axis, and the third axis in sequence to place the blocking triangle at the wheel blocking position. If the action fails to be in place each time during this process, an alarm is triggered and manual intervention is required.

[0021] Furthermore, the specific steps of the control system of the electric control box to remove the blocking triangle wood are as follows:

[0022] S21, after the tank truck is loaded, the tank stopper is automatically / manually started;

[0023] S21, move the third axis, the first axis, and the second axis in turn, remove the blocking triangle, and restore the mechanical parts to the position when the vehicle is not blocked. The vehicle drives away from the loading area. In this process, if the action fails to be in place each time, an alarm will be issued and manual intervention will be required.

[0024] The beneficial effects of the present invention are as follows: human involvement is avoided, and potential safety hazards to operators are greatly reduced; when tank trucks are frequently loaded and unloaded, or multiple vehicles are operating at the same time, the tank truck blocker device can automatically block the vehicles, which not only improves efficiency but also saves labor.
