Specific embodiment
To further appreciate that present disclosure, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.
Embodiment 1
With reference to Fig. 1 and Fig. 3, the balance crane of the lifting nut a kind of easy to disassemble of the present embodiment, it is adaptable to which carrying is not more than
The operating mode of 500KG.Including transmission case 11, top cover 12, counterweight 2, connecting plate, parallelogram rod member 4, motor 51, screw mandrel 52,
Lifting nut 53, connecting shaft 54 and column 8.Described column 8 is used to support transmission case 11, and the top of the transmission case 11 is provided with
Top cover 12, top cover 12 is fixed on transmission case 11 by screw, when need to dismantle lifting nut 53, quickly can be removed top cover 12,
Release 12 pairs of limitations of dismounting lifting nut 53 of top cover.
The left and right sides of transmission case 11 offers the first guide groove 111 and the second guide groove 112 respectively, is opened relative to tradition unification
If the structure design of vertical direction guide groove, the first guide groove 111, the second guide groove 112 include vertical guide groove and horizontal stroke in the present embodiment
To guide groove, vertical guide groove and lateral guide groove are spliced into inverted " L " type groove jointly, and the first guide groove 111, the difference of the second guide groove 112 exist
It is in opposite direction in opening up for respective lateral guide groove.By the opposite lateral guide groove structure design, during dismounting lifting nut 53 only
Need easily be rotated by 90 ° the wire winding rod 52 of lifting nut 53, lifting nut 53 and the connecting shaft 54 that is attached thereto just can be made to break away from the
The limitation of one guide groove 111 and the second guide groove 112, is allowed to be separated with transmission case 11, facilitates follow-up lifting nut 53 from screw mandrel 52
Upper back-out, smart structural design.
Described screw mandrel 52 is vertically arranged, and the screw mandrel 52 runs through transmission case 11, and its bottom is connected with motor 51, top insertion
In the hole that top cover 12 is opened up.Lifting nut 53 is arranged with screw mandrel 52, the left and right sides of lifting nut 53 is connected to connecting shaft
54, the connecting shaft 54 and the interference fit of lifting nut 53, screw mandrel 52, lifting nut 53, connecting shaft 54 collectively constitute whole balance
The slew gear for hanging, balance crane completes to move up and down by the slew gear.
Connecting shaft 54 through in inserting the first guide groove 111 and the second guide groove 112 after connecting plate respectively, what deserves to be explained is,
The present embodiment considers that subdivision lifting nut 53 can cause the transmission efficiency of lifting nut 53 to be damaged, therefore is changed to connect using subdivision
The mode of fishplate bar, will be originally used for holistic connecting plate and be split as connection lower plate 31 and connection upper plate 32, connection lower plate 31
One end connects counterweight 2, other end connection parallelogram rod member 4.Connection lower plate 31 and connection upper plate 32 are connected together axle 54,
And connection lower plate 31, connection upper plate 32 are flexibly connected by fixed plate 33 and fixing bolt 34, specially：Opened up in fixed plate 33
There is connecting hole, the connecting hole (i.e. connecting hole in fixed plate 33 corresponding with the connecting hole that opens up on connection lower plate 31, connection upper plate 32
Open up position and match with connecting hole on lower plate 31, connection upper plate 32 is connected), fixing bolt 34 is inserted in the connecting hole.This
Outward, it is contemplated that connection lower plate 31 and the reliability of the connection assembling of upper plate 32, the present embodiment are all provided with the left and right sides of connecting shaft 54
Fixed plate 33 (referring to Fig. 2) has been put, and each fixed plate 33 is fixed by 4 fixing bolts 34.Set by the structure of the present embodiment
Meter, when the abrasion of lifting nut 53 need to be changed, need to only remove fixing bolt 34, you can quickly by lifting nut 53 and other machines
Structure departs from, and saves the time of dismounting lifting nut 53.
It should be noted that, the present embodiment is heavier in view of the counterweight 2, parallelogram rod member 4 being connected with connecting plate,
If being lifted by manpower during dismounting lifting nut 53, intensity of workers is big and waste of manpower, is opened up on transmission case 11
First fixing hole 71, the second fixing hole 72 (referring to Fig. 3), first fixing hole 71, the second fixing hole 72 are in 11 liang of transmission case
Side opens up in pairs.Accordingly, fixing hole is also offered in described connection lower plate 31, connection lower plate 31 is by the band of lifting nut 53
Dynamic when rising to specified location, the fixing hole opened up in the connection lower plate 31 can be with the first fixing hole 71, the second fixing hole 72
With one heart.During lifting nut 53 to be removed, can be fixed on lower plate 31 is connected by inserting the first fix bar 61, the second fix bar 62
On transmission case 11, and then the counterweight 2 and parallelogram rod member 4 connected with lower plate 31 is connected also is secured, save dismounting
The manpower of lifting nut 53.
The process that the present embodiment specifically dismantles balance crane lifting nut is：
Step one, the control screw mandrel 52 of motor 51 are rotated, and lifting nut 53 drives and moved on connecting plate, and what is be connected with connecting plate is flat
Moved in weighing apparatus hammer 2 and the synchronization of parallelogram rod member 4, the fixing hole and the first fixing hole 71, second for extremely being opened up in connection lower plate 31
With one heart, be fixed on connection lower plate 31 fixing hole 72 on transmission case 11 by the first fix bar 61 of insertion, the second fix bar 62, without
Several staff lift counterweight 2 and parallelogram rod member 4, save manpower.
Step 2, take top cover 12 away, eliminate 12 pairs of limitations of dismounting lifting nut 53 of top cover, remove fixing bolt 34, will
Connection upper plate 32 is separated with connection lower plate 31, releases limitation of the connection upper plate 32 to connecting shaft 54.
Step 3, the control screw mandrel 52 of motor 51 are rotated, and are moved in the continuation of lifting nut 53, and now only connecting shaft 54 is with lifting
Nut 53 is upper together to be moved, and be located at the first guide groove 111, the lateral guide groove of the second guide groove 112 to connecting shaft 54 crosses with vertical guide groove
Place.
Step 4, the wire winding rod 52 of lifting nut 53 is rotated by 90 ° manually, makes lifting nut 53 and the connecting shaft being attached thereto
54 limitations for breaking away from the first guide groove 111 and the second guide groove 112, hand steered lifting nut 53, control lifting nut 53 is motionless, screw mandrel 52
Rotate backward, lifting nut 53 is screwed out, complete the disassembling section of lifting nut 53.
The method for dismounting of a kind of balance crane lifting nut described in embodiment 1, from the mode of subdivision connecting plate, transmission effect
Rate is unaffected, by the structure design for optimizing so that the replacing of lifting nut 53 is very convenient, improves the work of balance crane
Efficiency, and the process operation of dismounting balance crane lifting nut 53 is simple, it is time saving and energy saving, it is easy to utilize.
Schematical above that the present invention and embodiments thereof are described, the description does not have restricted, institute in accompanying drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So, if the common skill of this area
Art personnel enlightened by it, in the case where the invention objective is not departed from, is designed and the technical scheme without creative
Similar frame mode and embodiment, all should belong to protection scope of the present invention.
