Description

A crawler bulldozer capable of detecting the degree of track tension

technical field

The invention relates to a bulldozer, in particular to a crawler bulldozer which can detect the tension degree of the crawler belt.

Background technique

Bulldozer is a kind of common engineering machinery, which is widely used in various earthwork operations. Hydraulic bulldozers are the main mechanical equipment for earth and rock development, widely used in industrial and civil buildings. According to the technical status of hydraulic bulldozers at home and abroad, according to the different walking devices, they are divided into crawler type, tire type and walking type, etc. Bulldozers are easy to cause damage when walking. The overhang of the track exceeds the range of 10-20mm. When the overhang is too large, the track will vibrate and aggravate the wear of the chain rail joints, guide wheels, and sprocket tooth surfaces, which will easily cause chain drop. If the overhang is too small, the driving power will decrease. It increases sharply, and because there are many obstacles on the underground road surface, it is easy for sundries to get stuck in the track and so on.

Therefore it is very important to adjust the tension degree of the crawler bulldozer. The existing device is provided with a relaxation device or a tension device, which are both complicated and troublesome to operate, and the cost is also high.

The bulldozing device includes a The cantilever controlled by the hydraulic system on one side of the operating room and the bucket installed on the other end of the cantilever. The crawler traveling device includes a tension buffer mechanism, a track, a track frame, a guide wheel, a plurality of rollers and a chain. The track roller is located between the guide wheel and the sprocket. The track roller, the guide wheel and the sprocket are installed on the track frame. The track is set around the guide wheel, the support wheel and the sprocket, and the guide wheel, the support wheel It forms a wheel mechanism with the sprocket. The tension buffer mechanism includes a slide plate, a positioning plate, a positioning bolt, an electric push rod and a detection module for detecting the tension of the track. The positioning plate and the electric push rod are fixed on the track frame. The protruding end of the push rod drives the guide wheel to slide horizontally together by pushing the slide plate, through which the guide wheel slides horizontally to achieve the purpose of tensioning the track, and the positioning bolt passes through the slide plate to fix the slide plate in the positioning groove on the positioning plate to limit the free sliding of the slide plate .

The sprocket is connected with the power shaft of the transmission system.

The detection module includes a tension sensor installed on the track, a central processor and an alarm installed in the operating room, and the central processor controls the alarm alarm and the operation of the electric push rod according to the signal of the tension sensor.

The beneficial effects of the present invention are: the present invention can realize the function of adjusting the tension by using very few components such as a slide plate, a positioning plate and an electric push rod, and the electric push rod can be operated by remote control, which is very convenient to operate, and is equipped with a positioning The bolts can limit the free sliding of the slide plate by being fixed on the positioning plate. At the same time, when the electric push rod is not working, it can double cooperate to prevent the slide plate from sliding, so as to prevent the track from loosening. At the same time, a detection module can detect the tension of the track in time. situation and make timely adjustments.

detailed description

As shown in the figure, the specific implementation method is as follows:

A crawler bulldozer that can detect the degree of tension of the crawler belt, including a bulldozing device, an operating room 3, a crawler belt running device 4 and a transmission system, the transmission system drives the work of the bulldozer and the operation of the crawler belt running device 4, and the bulldozing device includes A cantilever 2 controlled by a hydraulic system with one end installed on one side of the operating room 3 and a bucket 1 installed on the other end of the cantilever 2. The crawler belt traveling device 4 includes a tension buffer mechanism, a crawler belt 401, a crawler frame, and a guide Wheel 409, a plurality of rollers 402 and sprocket 403, roller 402 is located between guide wheel 409 and sprocket 403, roller 402, guide wheel 409 and sprocket 403 are all installed on the track frame, track 401 Set around the guide wheel 409, the supporting wheel 402 and the sprocket 403, and the guiding wheel 409, the supporting wheel 402 and the sprocket 403 form a wheel mechanism, and the tension buffer mechanism includes a slide plate 408, a positioning plate 405, a positioning bolt 407, an electric The push rod 404 and the detection module for detecting the tension degree of the track, the positioning plate 405 and the electric push rod 404 are all fixed on the track frame, and the extended end of the electric push rod 404 drives the guide wheel 409 to slide horizontally together by pushing the slide plate 408, The purpose of tensioning the track 401 is achieved by the horizontal sliding of the guide wheel 409 , and the positioning bolt 407 passes through the sliding plate 408 to fix the sliding plate 408 in the positioning groove 406 on the positioning plate 405 to limit the free sliding of the sliding plate 405 .

The sprocket 403 is connected with the power shaft of the transmission system.
