Description
Technical field
The present invention relates to a kind of pin shaft connection structure, belong to element connection device field.
Background technology
The metal structure connection of tower crane typically adopts two ways, high strength exploitation or bearing pin to connect, wherein at present
Bearing pin is much all adopted to connect in tower crane component, conventional bearing pin connects and includes opening pin, axle end baffle plate formula.As shown in Figure 1
Opening pin bearing pin connects, and after bearing pin 1 without a head squeezes into connecting portion, bearing pin two ends are directly pinned with split pin, this kind of connection side
Formula can easy restriction bearing pin move axially, but cotter pin configuration stability is weaker, after the long period, easy to wear cuts
Break or come off;Axle end baffle plate formula bearing pin shown in Fig. 2 connects, and one end of shaft shoulder bearing pin 2 is the shaft shoulder 3, and has and baffle plate 5 cooperation
Notch, when bearing pin squeezes into connecting portion, axle end baffle plate 5 snaps in bearing pin notch, with 4 axle end baffle plates 5 of bolt and connecting portion
Position is fixing, and this kind of connected mode effectively can carry out axle head to bearing pin and fix, but when mounted, needs repeatedly to mate axle end baffle plate 5
With the relative position of bolt hole, lead to installation effectiveness relatively low.
Therefore, existing two kinds of pin shaft connection structures are not well positioned to meet actually used demand.
Content of the invention
The problem existing for above-mentioned prior art, the present invention provides a kind of pin shaft connection structure, can be prevented effectively from opening
Pin weares and teares or cuts off, and improves bearing pin and connects installation effectiveness, and can effectively play pin shaft end fixation.
To achieve these goals, a kind of pin shaft connection structure that the present invention adopts, including may be installed in connector
Bearing pin without a head, bearing pin two ends without a head all have pin shaft hole, also include being sleeved on bearing pin without a head for bearing pin axial limiting
Interstage sleeve, interstage sleeve is connected with bearing pin without a head by vertical pin, and one end of vertical pin has pin shaft hole, and the perforate end of vertical pin is locked equipped with fixation
Live mechanism.
Further, interstage sleeve is sleeved on the axle head of bearing pin without a head, and interstage sleeve has the installing hole installing vertical pin, and vertical pin passes through
After pin shaft hole on installing hole on interstage sleeve, bearing pin without a head, interstage sleeve is fixed on bearing pin without a head.
Further, locking device includes split pin for vertical pin axial limiting, is used for limiting split pin abrasion or cuts
Disconnected block, described split pin is arranged on the bearing pin in the hole of vertical pin, and described block is arranged on vertical pin.
Further, block is arranged between split pin and interstage sleeve.
Further, the aperture of interstage sleeve and the axle head diameter of bearing pin without a head coincide.
Further, backing plate is installed between interstage sleeve and connector.
Compared with existing bearing pin connected mode, the pin shaft connection structure of the present invention has the advantage that
(1) axle head in bearing pin without a head installs interstage sleeve, by interstage sleeve rotation process, can make vertical pin easily by interstage sleeve and nothing
Head bearing pin is cascaded, and installation effectiveness is high.
(2) pass through to install at the perforate end of vertical pin to pin structure, effectively vertical pin is fixed, it is to avoid vertical pin moving influence is without a head
The position of bearing pin, can effectively limit split pin abrasion simultaneously or cut off, make connection safety and reliability.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 4 and Figure 5, a kind of pin shaft connection structure, including the bearing pin without a head 1 that may be installed in connector, without a head
Bearing pin 1 two ends all have pin shaft hole, also include being sleeved on the interstage sleeve 8 being used for bearing pin axial limiting on bearing pin 1 without a head, interstage sleeve 8
It is connected with bearing pin 1 without a head by vertical pin 12, one end of vertical pin 12 has pin shaft hole, and the perforate end of vertical pin 12 is pinned equipped with fixation
Mechanism.
Interstage sleeve 8 is sleeved on the axle head of bearing pin 1 without a head, and interstage sleeve 8 has the installing hole installing vertical pin 12, and vertical pin 12 passes through gear
After installing hole on set 8, the pin shaft hole on bearing pin without a head 1, interstage sleeve 8 is fixed on bearing pin 1 without a head, is installed by vertical pin 12 solid
Determine interstage sleeve 8 and bearing pin without a head 1, simple and convenient, rapid operation is installed, and interstage sleeve 8 rotation is convenient it is easy to vertical pin 12 finds connection peace accurately
Dress hole.
As a further improvement on the present invention, locking device includes split pin 10 for vertical pin 12 axial limiting, is used for
Limit split pin 10 block 11 that weares and teares or cut off, described split pin 10 is arranged on the bearing pin in the hole of vertical pin 12, described gear
Block 11 is arranged on vertical pin 12, fixes vertical pin 12 by split pin 10, can play pin shaft end fixation, ensure that vertical
Pin 12 will not fall off, the installation of split pin 10, simple and easy to use, the block 11 in addition installed on vertical pin 12, can avoid growing
Time occurs abrasion to cut off using vertical pin 12 or comes off, and block 11 can effectively play a protective role to vertical pin 12.
Block 11 is arranged between split pin 10 and interstage sleeve 8, is prevented effectively from split pin 10 and contacts with interstage sleeve 8, prevents opening
Pin 10 abrasion is cut short or is come off.
The aperture of interstage sleeve 8 is coincide it is ensured that pin shaft end can be set with admittedly by interstage sleeve 8 just with the axle head diameter of bearing pin 1 without a head
Fixed, it is to avoid both gaps are excessive, bearing pin 1 without a head installs shakiness in interstage sleeve 8, and impact bearing pin normally uses.
Backing plate 9, energy effective protection interstage sleeve 8 and connector are installed, it is to avoid interstage sleeve 8 and connector between interstage sleeve 8 and connector
After directly contact, cause interstage sleeve 8 bottom or the abrasion on connector surface;In interstage sleeve 8 bottom, backing plate 9 is installed simultaneously, can be by interstage sleeve 8
It is stabilized in the axle head of bearing pin, the axle head fully realizing bearing pin is fixed.
During use, as shown in figure 5, bearing pin 1 without a head is squeezed into connector 6, after connector 7, gear loaded onto by bearing pin two ends set
Set 8, reuses vertical pin 12 and interstage sleeve 8 is connected with bearing pin 1 without a head, make interstage sleeve 8 be fixed on the axle head of bearing pin, the opening of vertical pin 12
Split pin 10 and block 11 is used to pin and fix again.
