Description

Technical Field

[0001] The utility model relates to the technical field of safety detection devices, in particular to an overweight detection device. Background Art

[0002] Since the mechanical parking operation mode is quasi-unmanned, the various types of mechanical parking equipment on the market currently only use thermal relays (current overload cut-off, signal feedback), and there is no special vehicle overweight detection device designed for real-time control. It is impossible to accurately measure the weight of the corresponding vehicle plate on the corresponding layer, and it is impossible to prevent vehicle damage due to misoperation. It can only manually observe whether the vehicle weight meets the weight requirements of the current layer. Manual observation of the vehicle weight is not particularly accurate, and there are always particularly large errors, and accuracy cannot be guaranteed. With the popularization of new energy vehicles, the dead weight of most models will gradually increase, and the overall frame structure will increase its bearing force. In order to meet the safety of the frame and improve the stability of the structure, in the lifting and lateral movement type structure mechanical equipment, the vehicle overweight detection is deepened and added, and the detection and judgment are carried out in real time during operation. Utility Model Content

[0003] The purpose of the utility model is to provide an overweight detection device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An overweight detection device comprises: a fixed rod and a transverse connecting rod, wherein the fixed rod and the transverse connecting rod are connected end to end to form a rectangular frame structure, and a detection mechanism is arranged on the fixed rod, and the detection mechanism is a shaft pin type weight sensor for detecting vehicle weight;

[0006] The detection mechanism includes: a sprocket, a chain, a pin and a weight sensor. The pin is fixedly connected to the inner side of a fixed rod, and the sprocket is rotatably connected to the outer wall of the pin through a bearing. The weight sensor is installed on the inner wall of the pin and is a shaft pin type weight sensor for detecting vehicle weight.

[0007] Preferably, a second chain is provided below the first chain and is installed on the inner side of the fixing rod via two other sets of sprockets.

[0008] Preferably, the fixing rod is a channel steel, and the inner side of the fixing rod is recessed.

[0009] Preferably, the chain 1 and the chain 2 are arranged in the channel steel, and a rectangular through hole is opened at the bottom of the channel steel for the chain 1 to movably pass through and be connected to the vehicle loading plate through the chain 1.

[0010] Preferably, two fixing rods and two transverse connecting rods are provided respectively, and the two fixing rods are connected to the two transverse connecting rods respectively through threaded rods.

[0011] Preferably, one side of chain one or one side of chain two is connected to a motor for driving the rod chain to rotate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When using the same set of equipment to park vehicles of different weights on different parking floors, it can prevent unnecessary losses caused by the lifting of the loading plate not meeting the rated weight of the current loading plate due to incorrect parking of vehicles;

[0014] 2. Since the original equipment does not have a corresponding detection device and purely relies on manual observation to see if the vehicle is overweight, it cannot guarantee that damage will not be caused by inaccurate weight judgment when someone parks the vehicle by mistake. The use of a vehicle overweight detection device greatly increases the safety of the equipment during operation and reduces the losses caused by misparking. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0024] like Figure 1-4 As shown, an overweight detection device comprises: a fixed rod 1 and a transverse connecting rod 5, the fixed rod 1 and the transverse connecting rod 5 are connected end to end to form a rectangular frame structure, and a detection mechanism 6 is provided on the fixed rod 1, and is an axle pin type weight sensor for detecting the weight of the vehicle;

[0025] The detection mechanism 6 includes: a sprocket 2, a chain 3, a pin and a weight sensor 4. The pin is fixedly connected to the inner side of the fixed rod 1, and the sprocket 2 is rotatably connected to the outer wall of the pin through a bearing. The weight sensor 4 is installed on the inner wall of the pin and is a shaft pin type weight sensor for detecting the weight of the vehicle.

[0026] Chain 2 is arranged below chain 1 3 and is installed on the inner side of the fixed rod 1 through another two sets of sprocket wheels 2.

[0027] The fixing rod 1 is a channel steel, and the inner side of the fixing rod 1 is concave. By setting the fixing rod 1 of the channel steel type, the mass of the fixing rod 1 can be reduced and its structural strength can be improved.

[0028] Chain 1 3 and chain 2 are arranged in the channel steel, and a rectangular through hole is provided at the bottom of the channel steel for chain 1 3 to pass through and connect with the vehicle carrier plate through chain 1 3. By providing a rectangular through hole at the bottom of the channel steel, chain 1 3 can be passed through the channel steel without affecting its use space, and the chain is located in the channel steel, which improves the stability of the chain during operation.

[0029] Two fixing rods 1 and two transverse connecting rods 5 are respectively provided, and the two fixing rods 1 are respectively connected to the two transverse connecting rods 5 through threaded rods. Connecting the fixing rods 1 and the transverse connecting rods 5 through threaded rods can improve their connection strength and convenience of installation.

[0030] A motor is connected to one side of chain 1 3 or one side of chain 2 for driving the rod chain to rotate. By setting a motor to connect one of the chains, the other chain is set as a driven chain, thereby reducing the equipment operation cost.

[0031] The working principle of the utility model is as follows:

[0032] When the vehicle overweight detection device is in use, it detects each corresponding column when the equipment is not running. When it is detected that the vehicle on the upper deck is overweight, the weight sensor 4 returns a signal to the PLC controller. The analog control unit of the controller detects through the internal running program and determines that the vehicle on this deck is indeed overweight. At this time, the operation panel will give an alarm for vehicle overweight failure. When the panel shows a vehicle overweight failure, it means that the weight of the vehicle on the corresponding deck does not meet the maximum load weight set for the current deck. At this time, the equipment cannot run. At this time, the vehicle on the corresponding deck needs to be driven out and parked in the correct position. Figure 3 For the electrical schematic, Figure 4 This is a diagram of the running program.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
