Description

Technical Field

[0001] The utility model belongs to the technical field of dump trucks, and in particular relates to a tilt monitoring device for dump trucks. Background Art

[0002] Dump trucks are widely used in construction, mining, agriculture and waste disposal, and are mainly used to transport and dump large quantities of bulk materials. The working principle is usually to control the tilt of the carriage through a hydraulic system to dump the materials in the carriage. It has the characteristics of pulling goods and automatically unloading.

[0003] When unloading, the safety of the dump truck needs to be considered. Therefore, safe unloading operations need to be performed in a safe working scene, and the driver is required to have certain professional knowledge and skills. However, since dump trucks are mostly used to transport bulk materials, their working scenes are mostly uncertain. Therefore, even if the driver has certain professional knowledge and skills, the ground of the working scene may be uneven. When loading heavy objects, in order to prevent the dump truck from tipping over, the existing technology mostly uses the method of limiting the rotation angle of the car body to reduce the probability of tipping over.

[0004] However, in actual usage scenarios, when loading heavy objects, if the ground is uneven, the carriage may not be turned to the restricted angle and may fall over along with the dump truck body. Utility Model Content

[0005] The purpose of the utility model is to provide a tilt monitoring device for a dump truck, so as to solve the problem that when the existing dump truck is in use, if the ground is uneven or the center of gravity of the cargo is offset, the dump truck body may tip over without the carriage being rotated to a position with a limited angle.

[0006] To achieve the above object, the utility model provides the following technical solutions: a tilt monitoring device for a dump truck, comprising a fixing plate and a metal rod located below the fixing plate, a fixing block is installed at the bottom of the fixing plate, a circular arc block is connected to the bottom end of the fixing block, the diameter of the metal rod is slightly smaller than the diameter of the inner side of the circular arc block, and the metal rod can be stuck in the arc of the circular arc block;

[0007] The arc block is slidably provided with a control block through the groove, and the control block includes a slider, which can slide in a direction close to or away from the metal rod. A stopper is fixed on the side of the slider close to the metal rod, and the metal rod acts on the stopper.

[0008] As a preferred embodiment of the utility model, a first threading post and a second threading post are fixed to a side of the fixed block away from the metal rod, a lead is slidably inserted in the first threading post and the second threading post, and a block is fixed to the end of the lead.

[0009] As a preferred embodiment of the present invention, a threading block is fixed to a side of the sliding block away from the metal rod, and the lead wire is slidably inserted into the threading block.

[0010] As a preferred embodiment of the present invention, the lead wire is constrained by the threading block to control the position of the block.

[0011] As a preferred embodiment of the present invention, the fixing plate is provided with a plurality of through holes penetrating through the two side walls thereof.

[0012] As a preferred embodiment of the utility model, a rotating block is rotatably connected to the bottom of the fixed plate, and the metal rod is fixedly connected to the rotating block via a connecting rod.

[0013] As a preferred embodiment of the present invention, two electrodes are provided through the side wall of the arc block.

[0014] Beneficial Effects

[0015] Technical effects and advantages of the dump truck tilt monitoring device:

[0016] When the dump truck tilt monitoring device is needed, if the ground is uneven during unloading, the uneven ground may cause the carriage to tilt with the dump truck body during the unloading process. At this time, the rotation angle of the carriage relative to the dump truck does not exceed the maximum rotation angle, but the rotation angle of the carriage relative to the ground exceeds the maximum rotation angle under normal unloading conditions. At this time, the arc block connects the two electrodes to transmit the signal that the dump truck is tilted. When the dump truck tilt monitoring device is in use, it can determine whether the dump truck has tilted according to the rotation angle of the carriage when the carriage has not rotated to the position with the restricted angle and tilts with the dump truck body.

[0017] When the dump truck equipped with the dump truck tilt monitoring device is in motion, the block can limit the rotation angle of the metal rod so that the metal rod will not stick to the electrode, thereby reducing the probability of triggering the dump truck tipping alarm during normal driving.

However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In order to avoid confusion with the present invention, some technical features known in the art are not described.

[0032] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0033] Please refer to Figure 1-Figure 5The dump truck tilt monitoring device shown in the figure includes a fixing plate 11 and a metal rod 23 located below the fixing plate 11. The fixing plate 11 is provided with a plurality of through holes 12 penetrating through its two side walls. When the dump truck tilt monitoring device needs to be used, the fixing plate 11 of the dump truck tilt monitoring device is tightly attached to the bottom of the vehicle body, and screws are passed through the through holes 12 and fixed to the bottom of the vehicle body. The dump truck tilt monitoring device can be fixed to the bottom of the vehicle body of the dump truck to monitor the tilt state of the vehicle body.

[0034] In this embodiment, a fixing block 31 is installed at the bottom of the fixing plate 11, and an arc block 32 is connected to the bottom end of the fixing block 31. The diameter of the metal rod 23 is slightly smaller than the diameter of the inner side of the arc block 32. The metal rod 23 can be stuck in the arc of the arc block 32. The arc block 32 is slidably provided with a control block through the groove 33 opened. The control block includes a slider 41. The slider 41 can slide in a direction close to or away from the metal rod 23. A stopper 43 is fixed on the side of the slider 41 close to the metal rod 23, and the metal rod 23 acts on the stopper 43.

[0035] A rotating block 21 is rotatably connected to the bottom of the fixed plate 11 , and a metal rod 23 is fixedly connected to the rotating block 21 via a connecting rod 22 .

[0036] like Figure 1 , Figure 2 As shown, a metal rod 23 is rotatably provided at the bottom of the fixed plate 11, and an arc block 32 is fixedly provided at the same time. The metal rod 23 cooperates with the arc block 32, and the control block can slide in the groove 33 of the arc block 32. The stopper 43 on the control block acts on the metal rod 23 to limit the rotation angle of the metal rod 23.

[0037] In this embodiment, a first threading column 34 and a second threading column 35 are fixed to a side of the fixed block 31 away from the metal rod 23, a lead 51 is slidably inserted in the first threading column 34 and the second threading column 35, a block 52 is fixed to the end of the lead 51, and a threading block 42 is fixed to a side of the slider 41 away from the metal rod 23, the lead 51 is slidably inserted in the threading block 42, and the lead 51 constrains the position of the control block through the threading block 42.

[0038] like Figure 3 , Figure 4 As shown, a block 52 is fixed to the end of the lead wire 51, and the lead wire 51 passes through the first threading post 34, the second threading post 35 and the threading block 42. In the driving state, the control block is squeezed by the block 52 toward the direction close to the metal rod 23, and the block 43 is exposed from the inner side of the arc block 32. At this time, the block 43 limits the rotation range of the metal rod 23, so that the metal rod 23 will not stick to the arc block 32.

[0039] like Figure 5As shown, when the carriage tilts, the block 52 pulls the threading block 42 and the control block through the lead wire 51 to move in a direction away from the metal rod 23, so that the stopper 43 no longer constrains the position of the metal rod 23. After rotating, the metal rod 23 can be attached to the arc block 32.

[0040] In this embodiment, two electrodes 36 are disposed through the side wall of the arc block 32 .

[0041] like Figure 3 As shown, according to the requirements, an alarm device can be set on the side of the fixing block 31 away from the metal rod 23 or the bottom of the fixing plate 11, and the two electrodes 36 are connected to the circuit of the alarm device, such as Figure 5 In this state, the metal rod 23 is attached to the arc block 32. At this time, the metal rod 23 connects the two electrodes 36, so that the alarm device is powered on and alarms are sounded, so as to monitor whether the dump truck is tilted.

[0042] Working principle: When the dump truck tilt monitoring device is needed, the fixed plate 11 of the dump truck tilt monitoring device is attached to the bottom of the dump truck compartment and fixed. When unloading, the fixed block 31 and the arc block 32 rotate with the tilt of the compartment. At this time, the metal rod 23 moves in the direction close to the arc block 32, but the metal rod 23 cannot be attached to the arc block 32 when unloading under normal unloading conditions. If the unloading is done on an uneven ground, the compartment may tilt with the dump truck body due to the uneven ground during the unloading process. At this time, the rotation angle of the compartment relative to the dump truck does not exceed the maximum rotation angle, but the rotation angle of the compartment relative to the ground exceeds the maximum rotation angle under normal unloading conditions. At this time, the object 52 pulls the control block through the lead 51 to move in the direction away from the metal rod 23, and the metal rod 23 is attached to the arc block 32. The arc block 32 connects the two electrodes 36 to transmit the signal of the dump truck tilt.

[0043] When the dump truck equipped with the dump truck tilt monitoring device is driving, the metal rod 23 will rotate due to factors such as bumps and speed changes. At this time, under the action of the object 52, the control block is always in a state close to the metal rod 23. At this time, the block 43 can limit the rotation angle of the metal rod 23 so that the metal rod 23 will not stick to the electrode 36.

[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
