Abstract

The utility model discloses a digger crawler-support turning-over fitting device which is characterized in that the device comprises four front supporter (1) supporting the crawler support and two rear supporter (2) s. Two left and right turning-over machine bases (3) are equipped between the front and the rear supporter (1, 2). The upper parts of the two turning-over machine bases (3) are respectively equipped with a turning-over shaft (4). The turnings-over tooling structure and operation of the utility model are very simple and have high reliability. The existing 5 ton or 3 ton wagons in workshop can be used as hoisting driving force without the need of special maintenance, which reduces total number of power units in the workshop, improves utilization rate of the wagons and saves cost price of equipment investment.

Description

Excavating machine track frame upset fitting device

Technical field

The utility model belongs to mechanical rigging equipment, is specifically related to the upset fitting device of track frame in a kind of excavating machine assembling.

Background technology

When 20/22 tonne of most widely used excavating machine is got off assembling in the engineering, to parts such as caterpillar wheel, track carrying wheel and track adjusting wheel be installed respectively at the right and left of its track frame, the weight of these parts is bigger, and during installation, general elder generation lifts on the track frame and could install with suspender; And these parts need be installed in the different parts of the top and the bottom of track frame, track frame must be turned over turnback when therefore assembling, the length of track frame is above 3.5 meters, width is above 2.5 meters, weight just surpassed 2300 kilograms before being unkitted other parts, realize that the required moment of upset is big, and the arm of force is long, can not be that power is realized rotary movement easily with the staff, must be by mechanical power; And operation can not hell to pay during upset, and the diverse location before and after the upset will make things convenient for the workman to carry out parts lifting and assembling.If adopt and self be equipped with dynamic special-purpose crawler belt positioning machine, its oad is big, complex structure, and price is high.During the batch manufacturing excavating machine, if the positioning machine that does not adopt customized design to make, the just essential relatively simply special overturn frock that adopts.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of structure and simple to operate is provided, and the reliability height needn't be safeguarded specially, saves the excavating machine track frame upset fitting device of equipment investment cost.

For solving the problems of the technologies described above, the utility model adopts following technical proposals: it comprises four preceding bearings and two rear supports of rest track frame, be provided with left and right two upset supports between forward and backward bearing, described two upset upper part of the frame respectively are provided with a trip shaft.

As further improvement, described upset support comprises base plate and the biside plate affixed with base plate, between biside plate, be connected with connecting plate, offer anchor (bolt) hole on the described base plate, biside plate top respectively offers a waist shaped hole, described trip shaft inserts the set waist shaped hole of biside plate from the upset support outside, and the end that trip shaft is positioned at the upset support outside is provided with a positioning plate.

The upset fitting device of excavating machine track frame of the present utility model is made up of left and right two the upset supports that are provided with between four preceding bearings of rest track frame, two rear supports and the forward and backward bearing, track frame can overturn around the trip shaft of upset upper part of the frame setting, assemble to be implemented in two positions that track frame turns over turnback, and the diverse location before and after the upset can carry out parts lifting and assembling easily; Needn't order or manufacture and design the special overturn machine of high price, save equipment investment cost.Upset tool structure of the present utility model and operation are very simple, and the reliability height needn't be safeguarded specially, do lifting power with workshop existing 5 tons or 3 tons of drivings and get final product, and have both reduced workshop total output device quantity, have improved the driving degree of utilization again.

The specific embodiment

As shown in Figure 1, 2, the upset fitting device of excavating machine track frame of the present utility model, according to the needs that parts are installed on track frame 6, assemble two positions that need to turn over turnback at track frame 6; Need the position of stop after consideration track frame 6 height dimensions and the upset, forward and backward two groups of bearings i.e. four preceding bearings 1 and two rear support 2 rest track frames 6 are set respectively, and the attachment face of its parts under the two states before and after the upset is horizontal substantially; Between forward and backward bearing 1,2, be provided with 3, two upset support 3 tops of left and right two upset supports and respectively be provided with a trip shaft 4.Shown in Fig. 3,4, upset support 3 comprises base plate 31 and the biside plate 32 affixed with base plate 31, the relative distance that biside plate is 32 can be placed the track frame 6 of corresponding type, between biside plate 32, connect and reinforcement with connecting plate 33, base plate 31, biside plate 32 and connecting plate 33 can adopt assembly welding to be connected, offer anchor (bolt) hole on the base plate 31, can be fixed on the ground by the holding-down bolt support 3 that will overturn; Biside plate 32 tops respectively offer a waist shaped hole, set trip shaft 4 inserts the waist shaped hole of biside plate 2 from upset support 3 outsides on the two upset supports 3, and pass on the track frame 6 hole that is used for apply lubrication oil (seeing Fig. 1,2) that the track adjusting wheel position is installed, an end that is positioned at upset support 3 outsides at trip shaft 4 is provided with a positioning plate 5, and is spacing to trip shaft 4.Can adopt two kinds of methods during lifting: a kind of is at the other end of the track frame 6 centers of gravity suspension rod of having packed into, and available 5 tons of drivings are done lifting power and driven track frame 6 upsets; Another kind is that lifting rope is passed the auxiliary hole that is positioned at the center of gravity other end, and available 3 tons of drivings are done lifting power and driven track frame 6 upsets.As shown in fig. 1, be positioned at the track frame 6 of rigging position A, be supported on the preceding bearing 1, when upset, track frame 6 rotates (C is depicted as and turns to the highest lifting position among Fig. 1) around the trip shaft 4 that passes wherein, overturn 180 ° to rigging position B, track frame 6 is supported on rear support 2 and the upset support 3.
