Abstract

The utility model discloses a fixed structure for middle counter weight of a crawler crane, which is arranged between a base of the crawler crane and a middle counter weight tray; the fixed structure comprises a counter weight pulling plate, one end of the counter weight pulling plate is connected with one side of the middle counter weight tray, far away from the base of the crawler crane, and the other end thereof is connected with the base of the crawler crane and is arranged above the middle counter weight tray. The counter weight pulling plate, the base of the crawler crane and the middle counter weight tray form a triangular diagonal brace fixed structure to fix a counter weight block in the middle counter weight tray, thereby improving the stability of the crawler crane in the moving process, enhancing the using intensity of the structure of the crawler crane and reducing the working noise.

Description

The fixed sturcture of crawler crane central authorities counterweight
Technical field
The utility model relates to a kind of fixed sturcture of crawler crane, relates in particular to the fixed sturcture of the central counterweight of a kind of crawler crane.
Background technology
The counterweight pallet of crawler crane hangs over the front and back of crawler crane base, and counterweight is positioned at the counterweight pallet, like this, can not only increase the stability of crawler crane, and, in the loading and unloading process, can reach certain anti-tipping effect at crawler crane.
In the said structure, central counterweight hangs on the crawler crane by the pallet peace, and is simple.But when crawler crane carried out short range and moves, because crawler crane is worked under the bad environment of road conditions usually and the rocking of crawler crane self, central counterweight pallet shake was severe.
Summary of the invention
The purpose of this utility model is to provide the fixed sturcture of the central counterweight of a kind of crawler crane, and this structure can be improved the stability of crawler crane in moving process, strengthens the working strength of crane structure, reduces operating noise.
For achieving the above object, the technical solution of the utility model is:
The fixed sturcture of the central counterweight of a kind of crawler crane, be arranged between crawler crane base and the central counterweight pallet, comprise the counterweight arm-tie, counterweight arm-tie one end is connected in central counterweight pallet away from crawler crane base one side, and an other end is connected in the crawler crane base and is positioned at central counterweight pallet top.
Be welded with two relative base otic placodes on the described crawler crane base, the corresponding two relative pallet otic placodes that are welded with on the central counterweight pallet, described counterweight arm-tie one end is connected between the base otic placode, and an other end is connected between the described pallet otic placode.
Described base and central counterweight pallet opposing end faces are formed with projection, and this projection is provided with positioning groove and base fixed orifice; Described central counterweight pallet comprises support arm, this support arm upper end is fixed with alignment pin, the alignment pin below is provided with and the corresponding pallet fixed orifice of described base fixed orifice, alignment pin is positioned at positioning groove, fixed pin shaft passes pallet fixed orifice and base fixed orifice, makes central counterweight pallet in the crawler crane base.
The beneficial effects of the utility model
The utility model connects the counterweight arm-tie between central counterweight pallet and crawler crane base, make counterweight arm-tie, crawler crane base and central counterweight pallet form leg-of-mutton brace fixed sturcture, central counterweight pallet is fixed on the crawler crane base, thereby prevent to be positioned at the clump weight shake of central counterweight pallet, improved the stability of crawler crane in moving process, strengthen the working strength of crane structure, reduce operating noise.
Description of drawings
Fig. 1 is the birds-eye view of the utility model one embodiment;
Fig. 2 is the front elevation of Fig. 1.
The specific embodiment
Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, the central counterweight fixed sturcture of crawler crane of the present utility model is arranged at crawler crane base 1 one sides, comprises central counterweight pallet 2 and counterweight arm-tie 3.
Be welded with two relative base otic placodes 11 on the base 1, base 1 is provided with projection 13 with central counterweight pallet 2 opposing end faces 12, and this projection 13 is provided with positioning groove 131 and base fixed orifice 132.
Central authorities' counterweight pallet 2 comprises support arm 21, these support arm 21 upper ends are fixed with alignment pin 22, alignment pin 22 belows are provided with and base fixed orifice 132 corresponding pallet fixed orifices 23, and the end away from base 1 on the central counterweight pallet 2 is welded with two relative pallet otic placodes 24.
The alignment pin 22 of the utility model central authorities counterweight pallet 2 is positioned at positioning groove 131, fixed pin shaft 4 and passes pallet fixed orifice 23 and base fixed orifice 132 and make central counterweight pallet 2 be hung on 1 one sides at the bottom of the crawler crane.Then, counterweight arm-tie 3 one ends are connected between the base otic placode 11 by bearing pin 5, an other end is connected between the described pallet otic placode 24 by another bearing pin 5, the top that one end of counterweight arm-tie 3 is positioned at central counterweight pallet 2 makes counterweight arm-tie 3, crawler crane base 1 and central counterweight pallet 2 form leg-of-mutton brace fixed sturcture, central counterweight pallet 2 is fixed on the crawler crane base 1, thereby the clump weight that is fixed in the central counterweight pallet 2 is shaken.
