Description

Technical Field

[0001] The utility model relates to the field of transport vehicles, in particular to an automatic alarm transport vehicle. Background Art

[0002] As an efficient tool for transporting goods, forklifts play an important role in improving work efficiency and reducing manual labor. They are widely used in places such as warehouses, factories, and supermarkets where goods need to be frequently transported. However, during use, forklifts are often forgotten or misplaced, resulting in the forklift being unable to be found when goods need to be transported, affecting work efficiency and even causing the forklift to be lost, increasing the company's operating costs. The traditional method of finding forklifts is to install a positioning system on the forklift to track its location. However, in complex environments, the accuracy of the positioning system may be affected by factors such as signal obstruction and multipath effects, resulting in inaccurate positioning and low vehicle search efficiency. At the same time, this method is not proactive and often requires the operator to first discover that the forklift is missing and then query the forklift's location through the system, which is time-consuming and has a slow response speed. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems of being unable to timely discover the loss of a transport truck and low efficiency in finding the truck, the utility model provides an automatic alarm transport truck with an active early warning mechanism. The operator can find the transport truck through the alarm, and the truck finding efficiency is high.

[0004] The specific technical solutions of the utility model are as follows:

[0005] An automatic alarm transport vehicle comprises a transport vehicle body, an alarm device and a key. The alarm device is installed on the transport vehicle body, and the key is connected to the transport vehicle parking point. The alarm device comprises an alarm and a monitoring and control component. The monitoring and control component comprises a monitoring device for monitoring the movement state of the transport vehicle and a control switch for controlling the on and off of the circuit of the alarm or monitoring device. The key is detachably connected to the control switch. When the key is connected to the control switch, the control switch is disconnected.

[0006] When a truck leaves its parking spot, the key is released from the control switch, which closes and activates the alarm system. A monitoring device monitors the truck's movement in real time. If the truck remains stationary for an extended period, the monitoring device sends a signal to the alarm, which recognizes the situation and immediately sounds an audible or visual alarm, allowing the operator to quickly respond and take action. The operator then returns the truck to its parking spot, inserts the key, disconnects the control switch, and deactivates the alarm system. The monitoring device transmits an alarm signal based on the truck's movement status, prompting any truck that hasn't returned to its designated location and is not in operation to sound an alarm to alert the operator. Simultaneously, the continuous audible or visual alarm helps the operator quickly locate the truck, improving vehicle retrieval efficiency.

[0007] Preferably, the transport vehicle parking spot is provided with a connecting rope, one end of the connecting rope is fixed to the wall of the transport vehicle parking spot, and the other end is fixed to the key.

[0008] In the above technical solution, the key is connected to the parking point of the transport vehicle by a connecting rope. The key has a large movable space and high flexibility. The operator does not need to adjust the position of the transport vehicle with effort, which improves the convenience of connecting the key and the control switch.

[0009] Preferably, the key is fixed on the wall of the truck parking spot.

[0010] In the above technical solution, the key is fixed in position, and the operator does not need to look for the key when parking the truck, which saves time and standardizes the parking position of the truck, making the truck parking spot look neat and orderly.

[0011] Preferably, the key is a magnetic key, the control switch is a magnetic switch, the magnetic key and the magnetic switch are attracted to each other by magnetic force, and the magnetic switch is in an off state when attracted to each other.

[0012] In the above technical solution, a magnetic connection is adopted between the magnetic key and the magnetic switch, which has an automatic alignment function, shortening the connection time. The magnetic switch automatically opens and closes according to the change of the magnetic field, avoiding the alignment difficulties and wear problems in traditional mechanical connections.

[0013] Preferably, the monitoring and control component includes a shell, the control switch and the monitoring device are installed in the shell, a magnet is provided on the shell at a position corresponding to the control switch, the key is made of magnetic metal material, and the control switch has a metal sensor for sensing metal. When the key is magnetically attracted to the shell by the magnet, the metal sensor senses the key and disconnects the control switch.

[0014] In the above technical solution, the key made of magnetic metal has good wear resistance and corrosion resistance, and can maintain stable magnetic properties in complex environments, which helps to ensure stable connection and reliable operation between the key and the control switch.

[0015] Preferably, the alarm device includes a battery assembly for powering the device, and the battery assembly is electrically connected to the alarm and the monitoring and control assembly.

[0016] In the above technical solution, in the alarm device, the battery assembly is electrically connected to other components, and each component is powered by the battery assembly, which helps to reduce the risk of device failure due to insufficient power of a single component. At the same time, when maintaining the transport vehicle, there is no need to check the power of each component of the alarm device separately, which simplifies the maintenance process.

[0017] Preferably, the battery assembly includes a shell and a battery body detachably mounted in the shell.

[0018] In the above technical solution, the shell is an openable structure, and the battery body is a storage battery or a disposable battery.

[0019] Preferably, the alarm device is detachably connected to the transport vehicle body.

[0020] In the above technical solution, the detachable connection facilitates regular inspection and maintenance of the alarm device. When the alarm device fails or requires maintenance, maintenance personnel can quickly remove it from the transport vehicle and perform separate repairs or replacements.

[0021] Preferably, the transport vehicle body includes a vertical frame, a storage platform and a plurality of wheels, the vertical frame is perpendicular to the storage platform and connected to the storage platform, and the wheels are connected to the storage platform; the alarm device is arranged on the vertical frame.

[0022] In the above technical solution, the alarm device is arranged on a vertical frame, which is easy to install, and there are few obstructions at this location, ensuring that the alarm sound it emits can be clearly conveyed to the operator, thereby improving the warning effect.

[0023] Preferably, the monitoring device consists of an acceleration sensor and a timer.

[0024] In the above technical solution, the acceleration sensor senses the change in the speed of the transport vehicle, and the timer sets the maximum static time. When the acceleration sensor still does not detect acceleration after exceeding the set time, it immediately sends a signal to the alarm to trigger an alarm.

[0025] Compared with the prior art, the utility model has the following advantages:
