Abstract
A limiting device for assembling and disassembling crawler frame belongs to a limiting device for assembling and disassembling engineering machinery, and comprises a limiting pin shaft hole and a limiting block, wherein the limiting pin shaft hole is in a semi-circular lift hook shape, the limiting block is in an oblique triangle shape, one end of the limiting pin shaft is connected with a spring card, and the limiting pin shaft hole and the limiting block are arranged on a crawler frame, a limiting pin shaft hole on a vehicle frame is a round hole, or the limiting pin shaft hole and the limiting block are both arranged on the vehicle frame, and a limiting pin shaft hole on the crawler frame is a round hole. The limiting device for assembling and disassembling crawler frame has the advantages that a semi-circular limiting pin shaft hole on the crawler frame and a limiting pin shaft which is pre-mounted on the vehicle frame can simply and quickly limit the crawler frame effectively, the limiting block can limit the crawler frame to move in a horizontal direction, and can simultaneously limit the crawler frame to move in a vertical direction to quickly align the positions of the crawler frame and the vehicle frame to assemble connecting pin shafts, and the limiting device for assembling and disassembling crawler frame is time-saving and labor-saving, and has high working efficiency.
Description
Technical field
The utility model relates to a kind of dismounting inhibiting device of construction machinery and equipment, particularly a kind of track frame dismounting inhibiting device.
Background technology
The assurance track frame is to be connected bearing pin with the vehicle frame normal operation, when track frame is installed, the relative frame fitting of track frame is aligned.Because the gap is less between connection bearing pin and the connecting pin axis hole, direct mount connection bearing pin is time-consuming, difficulty is very big.
At present, in order to improve installation effectiveness, when assembling track frame and vehicle frame, people use a kind of auxiliary inhibiting device.This inhibiting device includes square limiting stopper and circle hole shape limit pin hole, treat during assembling that track frame is adjusted to assigned address after, spacing bearing pin is assemblied on the vehicle frame.Because between spacing bearing pin and the track frame upper arresting pin axle mounting hole bigger gap is arranged, be convenient to install.But herein " be convenient to install " has bigger limitation, and locating dowel pin axle mounting hole all is circular hole on vehicle frame and track frame, and the crane relative position in track frame adjustment and vehicle frame hole that plays could be implemented installation after having only two holes to align, and it is time-consuming quite to require great effort; Utilize square limiting stopper to make track frame upper limit in the horizontal direction, the centering of auxiliary locating dowel pin axis hole, still relatively more difficult in practical operation, can not really reach the effect that when installing track frame is positioned fast installation.
The utility model content
The purpose of this utility model is to provide a kind of: the track frame dismounting inhibiting device that can position installation to track frame fast.
The purpose of this utility model is achieved in that this inhibiting device includes locating dowel pin axis hole and limiting stopper, and the locating dowel pin axis hole is semicircle suspension hook shape; Limiting stopper is an oblique triangle, at the end connection Spring Card of spacing bearing pin.
Described locating dowel pin axis hole and limiting stopper all are positioned on the track frame, and the locating dowel pin axis hole on vehicle frame is a circular hole; Perhaps described locating dowel pin axis hole and limiting stopper all are positioned on the vehicle frame, and the locating dowel pin axis hole on track frame is a circular hole.
Beneficial effect: owing to adopted such scheme, the locating dowel pin axis hole on the vehicle frame adopts circular hole, and adopts free-running fit, accurate positioning with spacing bearing pin.Install before the track frame earlier the locating dowel pin axle mounting on vehicle frame; Track frame upper arresting pin axis hole is semicircle suspension hook shape, and track frame is hung on the spacing bearing pin that is installed in advance on the vehicle frame, fast track frame is formed an effectively location; Adopt oblique triangle slab limiting stopper on the track frame, can be in the displacement of restriction track frame horizontal direction, restriction is also played in displacement in vertical direction to track frame.With track frame hang on the vehicle frame form the first step spacing after, adjust the direction of track frame, rely on limiting stopper that track frame is formed final location, realize that vehicle frame is connected the installation of bearing pin with track frame, can position fast track frame, reach the purpose of this utility model.
Advantage: track frame upper semi-circle locating dowel pin axis hole and the spacing bearing pin that is installed in advance on the vehicle frame can carry out effectively spacing simply fast to track frame, limiting stopper can limit the displacement of track frame horizontal direction, also can limit simultaneously track frame displacement in vertical direction, the position of centering track frame and vehicle frame is connected the bearing pin assembling fast, time saving and energy saving, high efficiency.

The specific embodiment
Embodiment 1: this inhibiting device includes locating dowel pin axis hole 6, spacing bearing pin 3 and limiting stopper 4, and locating dowel pin axis hole 6 is semicircle suspension hook shape; Limiting stopper 4 is the oblique triangle thick plate structure.Vehicle frame upper arresting pin axis hole is a circular hole, and track frame upper arresting pin axis hole is semicircle suspension hook shape; Locating dowel pin was installed on the vehicle frame before track frame is installed in advance, and an end of spacing bearing pin connects Spring Card; Limiting stopper is the oblique triangle thick plate structure.
Described locating dowel pin axis hole and limiting stopper all are positioned on the track frame, and the locating dowel pin axis hole on vehicle frame is a circular hole.
During use, the locating dowel pin axis hole 6 on the vehicle frame 1 adopts circular hole, and 3 of spacing bearing pins adopt free-running fit, accurate location.Before track frame 2 is installed, earlier spacing bearing pin 3 is installed on the vehicle frame 1, and installs and be used to the Spring Card 8 that prevents that spacing bearing pin 3 from withdrawing from; Locating dowel pin axis hole 6 on the track frame 2 adopts semicircle orifice suspension hook mode, and the radius of track frame locating dowel pin axis hole 9 is bigger, and this hole is half hole, can avoid normal lift heavy job time limit position bearing pin 3 stressed, causes the damage of spacing bearing pin 3.Simultaneously, the limiting stopper 4 on the track frame 2 adopts oblique triangle thick plate structure, can be in the 2 horizontal direction displacements of restriction track frame, and the restriction that displacement is in vertical direction also played to track frame 2.When track frame 2 is installed, the track frame locating dowel pin axis hole 9 of semicircle orifice hook formation can make track frame 2 hang on the spacing bearing pin 3 that is installed in advance on the vehicle frame 1 easily, fast track frame 2 is formed an effectively location, adjust the direction of track frame 2 then, rely on 4 pairs of track frames of limiting stopper 2 to form final location, realize that vehicle frame 1 is connected the installation of bearing pin 5 with track frame 2.
Embodiment 2: described locating dowel pin axis hole and limiting stopper all are positioned on the vehicle frame, and track frame locating dowel pin axis hole 9 is a circular hole, and there is track frame connecting pin axis hole 10 below of track frame locating dowel pin axis hole 9.
Other and embodiment 1 omit together.
