Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with attached
Figure and specific embodiment are described in detail.
As it is shown on figure 3, be counterweight and the attachment structure schematic diagram of body frame of an embodiment of the present invention, this is real
Executing and be fixed by counterweight attachment means 2 between the body frame 131 of example and counterweight 133, body frame 131 includes
First arm and the second arm, two arms are connected with counterweight 133 by a counterweight attachment means 2 respectively.
As Figure 4-Figure 6, for the structural representation of the counterweight attachment means of an embodiment of the present invention, this is joined
Reconnect device to include:
Bolt 22, its one end is connected with body frame；
Sleeve 23, including having threaded inwall 231 and having the outer wall 232 of protruding 233, is used for being set with
On the second end of described bolt, and threaded between described bolt；This projection is arranged on outside sleeve
On wall.
Connect seat 21, including one for the draw-in groove 212 with the protruding phase clamping of described sleeve, be used for being connected to
In counterweight.The modes such as this connection seat 21 welds with counterweight, bonding link together, and together with pouring thing
It is arranged in counterweight.
The counterweight attachment means of the present invention is by the sleeve being connected with bolt thread and the connection seat phase in counterweight
Clamping, when needs dismounting counterweight, can extract sleeve from connection seat, not damage connection seat, i.e.
Make counterweight repeatedly be dismantled, assemble cause screw thread damage, it is only necessary to be replaced bolt and sleeve,
Without changing whole counterweight, cost just can be greatly saved.
As it is shown in figure 5, be the structural representation of the sleeve of an embodiment of the present invention, the sleeve of this embodiment
23 include that inwall 231 and outer wall 232, outer wall and inwall are all cylindrical, form this sleeve between inside and outside wall.
This sleeve has internal thread, is i.e. provided with screw thread on this inwall 231.There are on this outer wall 232 two projections
233, two projections are symmetrically distributed in the relative position of outer wall.The inwall of this sleeve is threadeded with bolt 22,
And be sleeved on the second end of described bolt.
As shown in Figure 6, for the structural representation connecting seat of an embodiment of the present invention, this connection seat 21
Including card groove seat 211 and the draw-in groove 212 being arranged in card groove seat 211, this draw-in groove and the protruding phase on sleeve
Coordinate.This draw-in groove 212 can be the various applicable structures such as helicla flute.The sleeve of the present invention and connect seat it
Between be clamping, when dismantle counterweight time, sleeve can be extracted from draw-in groove, from without being damaged to counterweight
Connection seat, thus avoid replacing connect seat.In order to prevent protruding coming off when clamping, on draw-in groove
It is provided with block 213, prevents projection from coming off from draw-in groove by this block.
As it is shown in fig. 7, be the counterweight partial structurtes schematic diagram of an embodiment of the present invention, this connection seat 21
The base plate 1333 being welded in counterweight, this base plate has two arch grooves, this arch groove and the first arm of body frame
Matching with the second arm, the first arm and the second arm are inserted in one of encircleing in groove respectively, then utilize counterweight even
First arm and second arm of body frame are connected by connection device respectively with counterweight.Counterweight is stretched into for the ease of sleeve,
Being provided with hole 1334 on which floor plate, the sidewall of this hole is provided with the groove matched with upper described projection
1335, consequently facilitating sleeve is in hole stretches into counterweight.
Present invention also offers a kind of engineering machinery, this engineering machinery can be any machinery with counterweight,
Such as excavator, loading machine, fork truck etc..This engineering machinery includes counterweight, body frame and attachment means, should
Attachment means includes bolt, sleeve and connection seat, and described sleeve includes having threaded inwall and have projection
Outer wall, described sleeve set is on described bolt, and threadeds with the first end of described bolt, described
Second end of bolt is fixing with body frame to be connected；Described connection seat is connected in counterweight, including one for described
The draw-in groove of the protruding phase clamping of sleeve.The concrete structure of this attachment means sees above description.The work of the present invention
The counterweight of journey machinery is by the sleeve being connected with bolt thread and the connection seat phase clamping in counterweight, when needs are torn open
When unloading counterweight, sleeve can be extracted from connection seat, not damage connection seat, even if counterweight is repeatedly torn open
Unload, assemble cause screw thread damage, it is only necessary to be replaced bolt and sleeve, it is not necessary to change whole joining
Weight, cost just can be greatly saved.
The assembling process of the counterweight attachment means of the present invention is as follows:
1. being connected fixing to bolt and body frame, sleeve set is on bolt, and threadeds with between bolt；
2. rotational sleeve so that sleeve stretches in counterweight through counterweight base plate so that protruding alignment connects seat
Card notch；
Rotational sleeve the most again, is connected to the projection on sleeve in the draw-in groove connecting seat being positioned in counterweight,
It is achieved thereby that the fixing connection between counterweight and body frame.
The unloading process of the counterweight attachment means of the present invention is as follows: rotational sleeve so that the projection on sleeve takes off
From draw-in groove, it is rotated further sleeve so that sleeve departs from counterweight base plate, has reached convenient demounting bolt.Work as spiral shell
When screw thread on bolt goes wrong, can realize by changing bolt and sleeve.
Application technique scheme, the counterweight of the present invention with the attachment means of body frame by being connected with bolt thread
Sleeve and the connection seat phase clamping in counterweight, when needs dismounting counterweight, can be by sleeve from connecting seat
Extract, do not damage connection seat, though counterweight repeatedly dismantled, assemble cause screw thread damage, it is only necessary to
Being replaced bolt and sleeve, it is not necessary to change whole counterweight, cost just can be greatly saved.
The above is the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from principle of the present invention, it is also possible to make some improvements and modifications,
These improvements and modifications also should be regarded as protection scope of the present invention.
