Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transfer vehicles, and in particular relates to a multi-functional anti-collision device for warehouse transfer vehicles. Background Technology
[0002] A transfer cart, also known as a crane transfer cart, is used to move heavy items or equipment from one location to another. It can be used indoors or outdoors. Applications include metallurgy, casting, and new factory construction. Batteries power the transfer cart, with direct current flowing into the electrical box, which then supplies power to the operating system and motor. The motor's forward and reverse rotation and stopping are controlled using a handle or remote control, thus controlling the transfer cart's forward, backward, start, and stop. When the transfer cart moves within a warehouse, collisions are inevitable when personnel use the remote control, causing goods to shake or accidentally fall. Utility Model Content
[0003] In view of this, the present invention aims to propose a multi-functional warehouse transfer vehicle anti-collision device. The vehicle frame is equipped with obstacle avoidance sensors, PGV sensors and safety edge sensors to form a three-layer protection to reduce collisions and reduce the shaking or accidental falling of goods.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A multi-functional warehouse transfer vehicle anti-collision device includes a transfer vehicle, which comprises a frame and wheels. The frame is equipped with an obstacle avoidance sensor, a PGV sensor, and a safety edge sensor. The safety edge sensor is made of plastic and is positioned around the outer contour of the frame, protruding outwards. Two obstacle avoidance sensors are respectively located at the front and rear of the frame. A PGV sensor is located in the middle area of the frame. A color strip is provided on the warehouse floor for the PGV sensor to identify.
[0006] Furthermore, a multi-functional mounting slot is provided in the middle of the frame, which extends to the bottom of the frame, and the PGV sensor is located at the bottom of the multi-functional mounting slot.
[0007] Furthermore, the cross-section of the safety contact sensor is generally square or rectangular.
[0008] Furthermore, the safety edge sensor is located at the bottom of the vehicle frame.
[0009] Furthermore, the safety edge sensor is arranged around the entire length of the outer contour of the frame, and the safety edge sensor is provided with rounded corners at the four corners of the frame.
[0010] Furthermore, the two obstacle avoidance sensors are arranged diagonally along the vehicle frame.
[0011] Furthermore, the obstacle avoidance sensor is a laser-type obstacle avoidance sensor.
[0012] Furthermore, the transfer vehicle includes a motor and a PLC controller. The PLC controller is electrically connected to the motor, which is used to drive the wheels forward, backward, start, and stop. The signal input terminal of the PLC controller is connected to an obstacle avoidance sensor, a PGV sensor, and a safety edge sensor.
[0013] Compared with existing technologies, the anti-collision device for a multi-functional warehouse transfer vehicle described in this utility model has the following advantages:
[0014] The transport vehicle described in this invention is equipped with an obstacle avoidance sensor, a PGV sensor, and a safety edge sensor on its frame. The PGV sensor tracks the colored magnetic tape along the lane, controlling the transport vehicle to travel along the tape. The obstacle avoidance sensor detects obstacles, and based on signals collected by the obstacle avoidance sensor and the PGV sensor, it controls the drive wheels to move forward, backward, and start, achieving automatic obstacle avoidance and reducing collisions. When an obstacle presses against the safety edge sensor, the sensor generates a signal, and the equipment immediately stops; simultaneously, the safety edge acts as a buffer.
[0015] Safety edge sensors provide better cushioning to prevent goods from shaking or accidentally falling. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] like Figures 1 to 2 As shown, a multi-functional warehouse transfer vehicle anti-collision device includes a transfer vehicle, which includes a frame 3 and wheels 1. The frame 3 is equipped with an obstacle avoidance sensor 4, a PGV sensor 5, and a safety edge sensor 2. The safety edge sensor 5 is made of plastic material and is arranged around the outer contour of the frame 3. The safety edge sensor 2 protrudes outward from the frame 3. There are two obstacle avoidance sensors 4, which are respectively arranged at the front and rear of the frame 3. The PGV sensor 5 is arranged in the middle area of the frame 3. The warehouse floor is provided with a colored strip for the PGV sensor 5 to identify.
[0024] Specifically, the PGV sensor, also known as Position Guided Vision, consists of a camera system with a built-in illumination unit that reliably navigates via a ribbon tracking tape or paint.
[0025] The frame 3 has a multi-functional mounting slot 6 in the middle, which extends to the bottom of the frame 3. The PGV sensor 5 is located at the bottom of the multi-functional mounting slot 6. The multi-functional mounting slot 6 is used to mount heavy equipment, including hydraulic cylinders or rigid chains.
[0026] The safety edge sensor 2 has a generally square or rectangular cross-section. It is located at the bottom of the frame 3. The safety edge sensor 2 is positioned along the entire length of the outer contour of the frame 3, with rounded corners 7 at each of the four corners. When an obstacle presses against the safety edge sensor, a signal is generated, and the device immediately stops; simultaneously, the safety edge acts as a buffer.
[0027] Among them, the safety edge sensor 2 (or bumper sensor) is a device used for mechanical safety protection. It is usually installed on the edge of the machine equipment. In this embodiment, the safety edge sensor 2 adopts a mechanical micro switch type. Its structure mainly includes the edge and the mechanical micro switch inside the edge. The edge is usually made of silicone, rubber or polyurethane. Physical compression can directly trigger the micro switch and transmit the output signal to the control system, such as PLC controller or safety relay.
[0028] Two obstacle avoidance sensors 4 are arranged diagonally along the frame 3. The obstacle avoidance sensors 4 are laser-type obstacle avoidance sensors. Specifically, the PGV sensor is used for tracking the lane color tape and for navigation control. The laser-type obstacle avoidance sensor preferably uses the DE series 120° laser scanning obstacle avoidance radar sensor for AGVs, which can quickly and accurately detect obstacles, ensuring safe system operation.
[0029] The transfer vehicle includes a motor and a PLC controller. The PLC controller is electrically connected to the motor, which drives the wheels 1 forward, backward, start, and stop. The signal input terminals of the PLC controller are connected to obstacle avoidance sensors 4, PGV sensors, and safety edge sensors. Based on the signals collected by the obstacle avoidance sensors 4, PGV sensors, and safety edge sensors, the PLC controller controls the forward, backward, and stop movements of the driving wheels 1, enabling automatic obstacle avoidance to reduce collisions and prevent goods from shifting or accidentally falling.
[0030] A multi-functional warehouse transfer vehicle anti-collision device is disclosed. The vehicle frame is equipped with obstacle avoidance sensors, PGV sensors, and safety edge sensors, forming a three-layer protection. The first layer of anti-collision measure is the PGV sensor, which allows the equipment to operate along a pre-laid color strip within the warehouse. The second layer of anti-collision measure is the obstacle avoidance sensor, which constantly scans the surrounding environment while the equipment is moving. When an obstacle is detected, the equipment slows down or stops. The third layer of anti-collision measure is the safety edge sensor. When an obstacle presses against the safety edge sensor, the sensor generates a signal, and the equipment stops immediately. At the same time, the safety edge acts as a buffer. This three-layer protection can better reduce collisions and minimize the shaking or accidental falling of goods.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
