Description

Technical Field

[0001] The utility model relates to the field of engineering equipment, in particular to an excavator with an anti-collision alarm and a cooling and dust reduction device. Background Art

[0002] In modern construction operations, excavators are very commonly used engineering equipment. By replacing the front bucket, different construction needs can be met. When using an excavator on the construction site, the bucket is likely to generate dust when digging earth, polluting the air and construction environment. In severe cases, it will cause construction pollution to exceed the specified mark. When the excavator bucket is replaced with a hydraulic breaker to break the hard rock surface, the drill rod will accumulate internal energy under continuous impact and friction operations, and eventually the internal energy of the drill rod will be converted into heat energy to continuously heat the drill rod itself. If the drill rod cannot be cooled down for a long time, the strength and hardness of the drill rod will decrease under the action of continuous heating, resulting in damage. It is now urgently needed to design a device that can simultaneously cool down the excavator and reduce dust.

[0003] Chinese patent CN 115928730 A discloses a method for circumcision and cleaning of plain concrete pile heads, which specifically discloses a spray cooling device including a water tank, a water pump connected to the water tank, a hose connected to the output end of the water pump, and a nozzle connected to the water outlet end of the hose. The patent realizes water spray cooling and implicitly discloses water spray dust removal.

[0004] However, this technical solution still has technical defects. The addition of a complete set of cooling and dust removal devices changes the physical balance characteristics of the excavator itself. If the cooling and dust removal devices are improperly set, the excavator may easily overturn. During the rotation operation of the excavator, there is a lack of protection for the cooling and dust removal devices, which may easily cause collisions during the operation, causing the cooling and dust removal devices to be damaged and fail.

DETAILED DESCRIPTION

[0019] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0020] See also Figure 2 The utility model provides an excavator with an anti-collision alarm and a cooling and dust reduction device, comprising an excavator crawler 1-1, a rotating body 1-2 and an excavating arm 1-3 arranged on one side of the rotating body, and also comprising a cooling and dust reduction device, the cooling and dust reduction device comprising a nozzle 1-4 arranged at the front end of the excavating arm, a water pump 1-5 arranged on the rotating body 1-2 and a water tank 1-6 arranged on the other side of the rotating body 1-2, the water tank 1-6 is used to increase the counterweight of the rotating body 1-2 away from the side of the excavating arm 1-3 and supply water to the nozzle 1-4; see Figure 1 , an anti-collision alarm device, the anti-collision alarm device is arranged on the rotating fuselage 1-2 and is located on the same side of the water, 1-6, the anti-collision alarm device includes a first anti-collision facility 2-1 and a second anti-collision facility 2-2 welded perpendicularly to each other, the welding point of one end of the first anti-collision facility 2-1 and one end of the second anti-collision facility 2-2 is a step structure, a trigger-type early warning device 2-3 is arranged at the step structure, the other end of the first anti-collision facility 2-1 and the other end of the second anti-collision facility 2-2 are connected by a cold-bent arc-shaped I-beam 2-4, and a sensor 2-5 is arranged on the cold-bent arc-shaped I-beam 2-4 to connect the signal of the trigger-type early warning device 2-3.

[0021] Preferably, the trigger-type warning device 2-3 in this embodiment is a mechanical trigger-type warning, and the sensor 2-5 is an electronic trigger-type warning.

[0022] Preferably, a water level alarm 1-7 is provided in the water tank described in this embodiment.

[0023] Preferably, in this embodiment, the first anti-collision facility 2-1 and the second anti-collision facility 2-2 are I-beams.

[0024] Preferably, the peripheral side of the water tank 1-6 described in this embodiment includes a curved surface and a flat surface, and the curved surface has the same curvature as the curved surface on the peripheral side of the rear portion of the rotating body 1-2.

[0025] It is worth noting that the water tank 1-6 of the present invention is arranged on the rotating body 1-2 at one end away from the digging arm, so as to form a balance with the digging arm, so that the rotating body 1-2 becomes the center of gravity of the excavator, which increases the stability of the excavator when the digging arm is extended during the excavation process and reduces the possibility of rollover. The cooling and dust removal device can realize water spray cooling and dust removal according to the situation during the construction operation. The water in the water tank 1-6 will be sprayed out from the nozzle 1-4 transported by the water pump 1-5, and the water sprayed by the nozzle 1-4 will wet the excavator rod and the excavator working area.

[0026] The anti-collision warning device installed on the excavator has its outer arc surface protected by a cold-bent I-beam 2-4, and an electronically triggered sensor 2-5 is installed on the cold-bent I-beam 2-4. The sensor 2-5 can be an ultrasonic radar, an infrared distance detection, or a camera with object recognition analysis. When the sensor detects that the water tank is too close to the surrounding objects, it can alarm through an audible and visual alarm. The anti-collision warning device is protected horizontally and vertically by a first anti-collision facility 2-1 and a second anti-collision facility 2-2 composed of straight tube I-beams. When the first anti-collision facility or the second anti-collision facility collides with the surrounding objects, the slight deformation and displacement generated will cause the first anti-collision facility or the second anti-collision facility to touch the trigger-type warning device 2-3 and activate the collision. At this time, the trigger-type warning device 2-3 can sound and light to sound an alarm. The electronic trigger-type sensor has high accuracy, but it is easy to be damaged and fail because it is set on the side; the mechanical trigger-type sensor is reliable and durable and not easy to be damaged and fail, but because the alarm can be triggered only when the protective frame is slightly deformed and displaced, the accuracy is poor. The combination of the two makes the anti-collision warning device of the device have both reliability and accuracy.

[0027] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
