Abstract
The invention discloses a waist strap chain regulator. The waist strap chain regulator comprises a main body, pulling board connecting holes positioned in the top of the main body, chambers used for installing a chain, and pin shaft fixing holes; the chambers match with chain circular rings; and the pin shaft fixing holes are arranged at the lower portion of the main body. The waist strap chain regulator has the advantages of adjustment of the length of a waist strap through adjusting the access number of the chain circular rings, simple structure, easy operation, and solving of the easy interference problem of the falling process of a super tonnage waist strap to jib system accessories.
Description
Technical field
The present invention relates to a kind of waist rope chain adjuster, belong to technical field.
Background technology
Along with lifting altitude, hang carry an amplitude constantly increase, jib length is also in corresponding increase, loading capability is hung in order to not sacrifice, require that again jib weight is as far as possible light, this just brings the problems such as deflection of arm support is large, overstressing, cannot meet the demands, waist rope device arises at the historic moment in this case, and waist rope connection diagram as shown in Figure 1.Due to on-site hoisting need determine hang carry height different with amplitude, require different brachiums, this just needs corresponding different waist rope length, and super-tonnage crane waist rope power is larger, general employing chain form meets the demands, as shown in Figure 2, this structure can meet the requirement of the stressed and waist rope adjustable in length of waist rope, but complex structure, porous regulating plate volume in figure, weight are large, between jib, space is little, installs difficulty, in waist rope dropping process regulating plate easily and on jib annex interfere.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of structure simple, little, the lightweight new-type chain adjuster of volume, by the length regulating the effective annulus number being connected into waist rope to adjust waist rope, breaker plate is adjusted length and change movable annulus adjustment into, structure is simple, easy to operate.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of waist rope chain adjuster, company's arm-tie hole of the described body top that it is characterized in that, comprise main body, is positioned at, for assigning chamber and the set pin axis hole of chain; Described chamber and chain annulus match; Described set pin axis hole is arranged on the bottom of main body.
Aforesaid a kind of waist rope chain adjuster, it is characterized in that, described chamber has been arranged side by side several.
Aforesaid a kind of waist rope chain adjuster, it is characterized in that, the communication direction of described set pin axis hole runs through the chamber be arranged side by side.
Aforesaid a kind of waist rope chain adjuster, it is characterized in that, the end of described set pin axis hole is provided with fixation clamp; Described set pin axis hole is furnished with fixed pin shaft.
The beneficial effect that the present invention reaches: this device reaches the object of adjustment waist rope length by the access number of adjustment chain annulus, and structure is simple, easy to operate, to solve in super-tonnage waist rope dropping process easily and problem that boom system annex is interfered.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
A kind of waist rope chain adjuster that the present invention relates to, comprises main body 1, for assigning chamber 7 and the set pin axis hole 5 of chain 2.The company's of being provided with arm-tie hole 6 above main body 1, the bottom of main body 1 is provided with set pin axis hole 5.Chamber 7 and chain annulus match, and chamber 7 has been arranged side by side several, can realize the use of multichain bar institutional adjustment length, thus improve the endurance quality of self.The communication direction of set pin axis hole 5 runs through the chamber 7 be arranged side by side, and the end of set pin axis hole 5 is provided with fixation clamp 4, is used for fixing fixed pin shaft 3.
As shown in Figure 3, the embodiment of two that to be chamber 7 be.When carrying out actual use, first according to according to hang carry, highly, amplitude, determine brachium and waist rope length, calculate the chain 2 effectively joint number being connected into waist rope, then most for effective chain 2 minor details are loaded chain adjuster, insert bearing pin, installation clip 4, finally chain adjuster upper end is connected into arm-tie by connecting arm-tie hole 6, lower end and jib are fixed, thus complete operation.
Structure more common in prior art as shown in Figure 2, this structure carries out length adjustment by porous regulating plate, and regulated the length of waist rope by the adjustment installation site of axle on regulating plate, the hole on regulating plate is fixing, in order to meet all waist rope length, cause porous regulating plate length large, weight is large, installs difficulty, and easily cause and annex interference problem on jib, and chain more replacings position bothers more, operating difficulties.
And regulating control involved in the present invention, be load chain from the side of cavity and fix Anti-extrusion with bearing pin, the use of chain and even multichain bar institutional adjustment length can be realized, greatly increase range of use and the alerting ability of this device.After actual installation uses, if find that chain length still needs fine setting, directly can adjust the chain number connecting jib one end, operation is very easy.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
