Abstract
The utility model discloses a crawler crane control tensioning crawler plate device, which comprises a guide wheel (5), a crawler beam (3) and an adjusting gasket (4), wherein a jack (1) is arranged on the crawler beam (3), one end of a tension plunger (2) is connected with a plunger of the jack (1), and the other end of the tension plunger (2) is connected with a main shaft of the guide wheel (5) through a support mode. The guide wheel can be steadily supported forwardly by the tension plunger during the adjusting process of the crawler crane control tensioning crawler plate device, a crawler is tightened to 8-10mm by the tension plunger, and then the adjusting gasket (4) is filled up between the guide wheel and the crawler beam to fix the tighten degree of the crawler. The crawler crane control tensioning crawler plate device solves the problems that an original rotating lead screw tensioning device wastes effort, is not high in efficiency and is not safe. The crawler crane control tensioning crawler plate device can lightly, effectively and safely adjust a tensioning crawler plate through the jack.
Description
Technical field
The utility model relates to a kind of adjusting tensioner caterpillar block device, and particularly a kind of crawler crane is regulated the tensioned tracks panel assembly.
Background technology
In view of badly drive wheel, track adjusting wheel, caterpillar block generation severe wear, caterpillar block broken teeth, track adjusting wheel being twisted off of crawler crane working environment, so extremely important in the elasticity of regulating crawler belt, should guarantee that the crawler belt sag between the two holder sprocket wheels is 8～10mm.Because crawler belt in the process of regulating and drive wheel produce that so the larger power of tightening is required great effort when the adjusting very much and dangerous.
At present crawler crane adjusting tensioned tracks panel assembly all is to regulate with the manual rotation screw mandrel, but this kind control apparatus is quite required great effort when regulating, efficient is not high, dangerous.
The utility model content
Technical problem to be solved in the utility model provides a kind of crawler crane that can regulate easily, efficiently and safely the tensioner caterpillar block and regulates the tensioned tracks panel assembly.
In order to solve the problems of the technologies described above, the crawler crane that the utility model provides is regulated the tensioned tracks panel assembly, comprise track adjusting wheel, track beam and adjustment pad, be provided with jack at described track beam, tensioning push rod one end is connected with the push rod of described jack, the main shaft apical grafting of the other end of described tensioning push rod and described track adjusting wheel.
Adopt the crawler crane of technique scheme to regulate the tensioned tracks panel assembly, utilizing iron rod to swing jack makes its promotion tensioning push rod top tighten crawler belt assurance crawler belt sag 8～10mm to the main shaft of track adjusting wheel, to adjust the pad pad to fixing crawler belt degree of tautness between the main shaft of track adjusting wheel and the track beam, the recycling jack is retracted to the initial position with the tensioning push rod again.Adopt jack to regulate the tensioned tracks plate, adjusting tensioned tracks plate that can be light, efficient, safe.
In sum, the utility model has solved former rotary screw tightening device effort, not high, the dangerous phenomenon of efficient, adopt jack to regulate the tensioned tracks plate, adjusting tensioned tracks plate that can be light, efficient, safe is that a kind of crawler crane that can regulate easily, efficiently and safely the tensioner caterpillar block is regulated the tensioned tracks panel assembly.
Description of drawings
Fig. 1 is existing adjusting tensioner caterpillar block apparatus structure scheme drawing.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, at present crawler crane adjusting tensioned tracks panel assembly all is to regulate with manual rotation screw mandrel 7, but this kind control apparatus is quite required great effort when regulating, efficient is not high, dangerous.
Referring to Fig. 2, be provided with jack 1 at track beam 3, tensioning push rod 2 one ends are connected with the push rod of jack 1, and the main shaft apical grafting of the other end of tensioning push rod 2 and track adjusting wheel 5 is provided with between the main shaft of track adjusting wheel 5 and the track beam 3 and adjusts pad 4.
Referring to Fig. 2, utilizing iron rod to swing jack 1 makes its promotion tensioning push rod 2 tops tighten crawler belt 6 assurance crawler belts 6 sags 8～10mm to the main shaft of track adjusting wheel 5, to adjust pad 4 again and fill up to fixing crawler belt degree of tautness between the main shaft of track adjusting wheel 5 and the track beam 3, recycling jack 1 is retracted to the initial position with tensioning push rod 2.Utilize iron rod to swing jack 1 and make tensioning push rod 2 tops tighten crawler belt to the main shaft of track adjusting wheel 5, energy is light, efficient, safety realizes aforesaid operations.
