Description

Technical Field

[0001] The utility model relates to the technical field of the alignment of the parking spaces of tank trucks, in particular to an alignment device for the parking spaces of tank trucks used in blast furnaces. Background Technique

[0002] The main function of a blast furnace tank truck is to safely and efficiently transport the molten iron smelted in the blast furnace to the steelmaking workshop or other designated locations. A rail type molten iron level gauge is used to weigh the weight of the molten iron introduced into the tank body, and then the height of the molten iron in the pipe body is calculated to avoid overfilling and overflowing of the tank body with molten iron. To ensure accurate weighing, a high-precision parking requirement for the tank body frame is needed. If there is a deviation in the parking position, all axles will deviate from the effective weighing area, resulting in weighing deviation and unable to provide accurate data for the molten iron operator, thus causing molten iron overflow. The traditional parking alignment is achieved by setting obvious marks on the ground or wall, and the driver judges whether it is aligned through the marks. This alignment method is too subjective and prone to deviation.

[0003] To solve the above problems, the patent publication number: CN206876186U provides a parking monitoring and positioning detector, which includes a signal transmitting part and a signal receiving part. The signal transmitting part is installed on the vehicle, and the signal receiving part is installed on the building. The signal transmitting part includes a light beam emitting element and a confirmation information transmitting component. The light beam emitting element is installed on one side of the vehicle body, and the confirmation information transmitting component is installed at the front of the vehicle and the parking space. The signal receiving part includes a photosensitive signal detector, and the photosensitive signal detector is fixed on the slideway through a slide plate. The accuracy of parking is increased by the signal transmitting part and the signal receiving part. However, the above patent uses the emitted light beam as the signal of the detector, which is only applicable to indoor environments with relatively dim light and is easily affected by external light in outdoor environments with sufficient light, and is not suitable for the alignment of tank truck parking spaces. Content of the Utility Model

[0004] The purpose of the utility model is to provide an alignment device for the parking spaces of tank trucks used in blast furnaces to solve the problem that in outdoor environments with sufficient light, the light beam emitting element of the existing patent is easily affected by external light and is not suitable for the alignment of tank truck parking spaces.

[0005] To achieve the above purpose, the basic solution provided by the utility model is: an alignment device for the parking spaces of tank trucks used in blast furnaces, which includes a proximity switch. A support mechanism for fixing the proximity switch is provided on the proximity switch. The support mechanism is bolted to the track. The output end of the proximity switch is electrically connected to a PLC controller, and the PLC controller is electrically connected to an alarm.

[0006] The principle and beneficial effect of the utility model are as follows: when the front wheel of the tank truck reaches the designated parking point, since the front wheel is made of metal, the sensing surface of the proximity switch releases a magnetic field. When the front wheel approaches the sensing surface, the internal circuit of the proximity switch will change, and a switch signal will be sent to the PLC controller through the signal output line, so that the alarm will work.

[0007] Option 2 is the preferred option of the basic option. The support mechanism includes a connecting frame with a bar hole on the connecting frame. The proximity switch and the bar hole are movable through the connection. The proximity switch is provided with a limit assembly for limiting the movement of the proximity switch. When the support mechanism and the track bolts are connected, they are used to adjust the position of the proximity switch in a small range to increase the accuracy of the tanker parking point.

[0008] Option three is the preferred option of option two. The limit assembly includes two limit plates and a basket bolt. The two limit plates are located on both sides of the bar hole. The limit plates and the proximity switch are threadedly connected, and the two limit plates are connected by a basket bolt. After adjusting the position of the proximity switch, the two limit plates are tightened by the basket bolt.

[0009] Option 4 is the preferred option of Option 3. Handles are provided at both ends of the turnbuckle to facilitate the rotation of the turnbuckle.

[0010] Option 5 is the preferred option of Option 4. The limit plate, basket bolt, connecting frame and handle are all made of phenolic plastic to reduce the impact on the proximity switch.

[0011] Option six, which is the preferred option of the basic option, the proximity switch is an inductive proximity switch. BRIEF DESCRIPTION OF THE DRAWINGS
