Description
Technical field
This utility model belongs to tower crane balance weight fixing device technical field, and specifically a kind of tower crane balance weight installs dress
Put.
Background technology
The balance weight of large-scale tower crane generally uses bearing pin to be arranged on tower crane counterweight support, when balance weight is installed, and first will be flat
Weight hangs in the slot of counterweight rack beam from the bottom to top, and the lug plate holes on balance weight both sides respectively through a bearing pin, is shelved on
On crossbeam in corresponding channel bar, then by balance weight draw lever locking, multiple balance weights are connected into an entirety.This company
Connect mode structure complexity, operation inconvenience, it is often more important that balance weight has certain foozle in casting process so that balance
Leave certain gap when focusing on installation each other, cause tower crane balance weight when normal work to be rocked before and after bearing pin, phase
Mutual friction is collided and produces chip, the most fragile balance weight, also leaves hidden danger to safety in production.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of tower crane balance weight erecting device, its structure letter
Single, be easily maintained, widely applicable.
For realizing above-mentioned technical purpose, the scheme that this utility model provides is: a kind of tower crane balance weight erecting device, including
Crossbeam, main chord, pin and web member, one end of crossbeam is 90 ° with main chord and welds, and the other end is by otic placode and installs bearing pin even
Connecing pin, described crossbeam is that two channel-section steels that are opposing and that be welded by batten plate are constituted, and leaves for pacifying between two channel-section steels
The slot of dress balance weight, symmetrical and be welded with multipair oblique support plate, every piece of balance weight evenly and at intervals on the channel-section steel of slot both sides
Otic placode through slot hanging on load-bearing bearing pin, load-bearing bearing pin is held on a pair oblique support plate, and load-bearing bearing pin
Both sides are respectively provided with for being stuck in the groove on oblique support plate.
And, the inclination angle of inclined plane of described oblique support plate is not more than 15 °.
And, near spacing between oblique support plate and pin described in a pair of pin no less than 100mm, and this
Tail end to oblique support plate is higher than other oblique support plate.
The beneficial effects of the utility model are: use oblique support plate to replace channel bar, due to balance weight self gravitation
Effect, polylith balance weight is mutually extruded from being integrated after installing, thus solves to rock when existing balance weight is installed to ask with collision
Topic, it also avoid the hidden danger leaving safety in production.It addition, carry out solid without increasing balance weight pull bar when this tower crane balance weight is installed
Fixed, also reduce production cost and the installation difficulty of weight-balancing device.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
The present embodiment provides a kind of tower crane balance weight erecting device, as shown in Fig. 1 ~ Fig. 3, including crossbeam 1, main chord 2, gear
Bar 3 and web member, one end of crossbeam 1 welds in 90 ° with main chord 2, and the other end is by otic placode and installs bearing pin and connects pin 3.Main
Many straight, diagonal web members 4 are welded between chord member 2.
Described crossbeam 1 is that two channel-section steels that are opposing and that be welded by batten plate are constituted, leave between two channel-section steels for
The slot of balance weight 7 is installed.
On the channel-section steel of slot both sides symmetrical and be welded with multipair oblique support plate 5 evenly and at intervals, oblique support plate 5 is right angle
Triangle, angle is unsuitable excessive, generally less than 15 °.Spacing between a pair oblique support plate 4 and the pin 3 of pin 3
No less than 100mm, its objective is that the production error for balance weight 7 leaves move place, prevent balance weight 7 because there being production by mistake
Difference and fill situation about unmatching.And the tail end of this pair oblique support plate 4 is higher than other oblique support plate 4, prevents balance weight 7
Slip.
The otic placode of every piece of balance weight 7 through slot hanging on load-bearing bearing pin 6, load-bearing bearing pin 6 be held on a pair oblique
On support plate 4, and the both sides of load-bearing bearing pin 6 are respectively provided with for being stuck in the groove 6.1 on oblique support plate 4, as shown in Figure 4, anti-
Only load-bearing bearing pin 6 axial float.
After this programme assembles, balance weight 7 is under the effect of self gravitation, the most crowded along the inclined-plane of oblique support plate 5
Tightly become an entirety, it is to avoid leaving gap between existing balance weight 7, work is rocked time around, mutual frictional impact also produces
Raw chip, the problem leaving hidden danger to safety in production.It addition, carry out without increasing balance weight pull bar when this tower crane balance weight is installed
Fixing, also reduce the production cost of balance weight erecting device.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvement or deformation, these improve or
Deformation also should be regarded as protection domain of the present utility model.
