Abstract

The utility model relates to a reinforcement lifting appliance for a crane. The reinforcement lifting appliance comprises a channel steel frame, a hexagonal shaft, a cylinder support, a cylinder, a joint, a rotary arm, a cam and a hanging rod, wherein the hexagonal shaft is mounted on the channel steel frame through a mounted bearing, the cylinder is mounted on the cylinder support through a cylinder seat, one end of the joint is connected with the cylinder, the other end of the joint is pivotally connected with the rotary arm through a first pin, the hexagonal shaft is fixed to the lower portion of the rotary arm, the hanging rod is pivotally connected onto the channel steel frame through a second pin, and the cam is mounted on the hexagonal shaft, is abutted to the hanging rod and can drive the hanging rod to rotate. The reinforcement lifting appliance for the crane is used for accurately and rapidly lifting reinforcements, is high in lifting efficiency, no longer needs manual clamping and accordingly is safe to use.

Description

A kind of hoisting crane reinforcing bar suspender

Technical field

The utility model relates to a kind of suspender, is specifically related to a kind of heavy-duty machine reinforcing bar suspender, belongs to the vehicle for construction technical field.

Background technology

At present, pile tube needs to use the crane hanging component reinforcing bar in manufacturing process.And reinforcing bar is in when lifting, generally by the operative employee with the riggings such as steel rope tighten be placed under the crane hanging beam lift by crane, in place.Like this, not only labor strength is large, and is also dangerous, and reinforcing bar unloads in place also slowlyer, and efficient reduces greatly.

Therefore, for solving the problems of the technologies described above, the necessary hoisting crane reinforcing bar suspender that a kind of novel structure is provided is to overcome described defective of the prior art.

The utility model content

For addressing the above problem, the purpose of this utility model be to provide a kind of in place quick and precisely, use safety and the high hoisting crane of efficient reinforcing bar suspender.

For achieving the above object, the technical scheme that the utility model is taked is: a kind of hoisting crane reinforcing bar suspender, and it comprises U-steel frame, hexagonal axis, air cylinder support, cylinder, joint, pivoted arm, cam and bridging bar; Wherein, described hexagonal axis is installed on the U-steel frame by rolling bearing units; Described cylinder is installed on the air cylinder support by a cylinder block; Described joint one end connects cylinder, and the other end is articulated by one first bearing pin and pivoted arm; The bottom of described pivoted arm is fixed with hexagonal axis; Described bridging bar is articulated on the U-steel frame by one second bearing pin; Described cam is installed on the hexagonal axis, and it is connected on the bridging bar and can drives the bridging bar and rotates.

Hoisting crane of the present utility model further is set to the reinforcing bar suspender: described U-steel frame is symmetrically distributed in the both sides of air cylinder support.

Hoisting crane of the present utility model also is set to the reinforcing bar suspender: it is installed on the bottom of a hanging beam.

Compared with prior art, the utlity model has following beneficial effect: hoisting crane of the present utility model is accurately rapid when the lifting reinforcing bar with the reinforcing bar suspender, and lifting efficient is high, and no longer needs artificial clamping and use safety.

The specific embodiment

See also Figure of description 1 to shown in the accompanying drawing 5, the utility model is a kind of hoisting crane reinforcing bar suspender, it is installed on the bottom of a hanging beam 9, and it is formed by a few part assemblings such as some U-steel frames 1, hexagonal axis 2, air cylinder support 3, cylinder 4, joint 5, pivoted arm 6, cam 7 and bridging bar 8.

Wherein, described hexagonal axis 2 is installed on the U-steel frame 1 by rolling bearing units 21, and it is and is horizontally disposed with.These U-steel frames 1 are symmetrically distributed in the both sides of air cylinder support 3.

Described cylinder 4 is installed on the air cylinder support 3 by a cylinder block 41.Described joint 5 one ends connect cylinder 4, and the other end is articulated with pivoted arm 6 by one first bearing pin 51.The bottom of described pivoted arm 6 is fixed with hexagonal axis 2.This cylinder 4 promotes pivoted arm 6 by joint 5 successively and rotates, and rotates thereby make pivoted arm 6 drive hexagonal axis 2.

Described bridging bar 8 is articulated on the U-steel frame 1 by one second bearing pin 81.Described cam 7 is installed on the hexagonal axis 2, and it is connected on the bridging bar 8 and can drives bridging bar 8 and rotates.

Hoisting crane of the present utility model is as follows with the principle of work of reinforcing bar suspender: shown in Figure of description 2 and 3, when suspender was in the lifting position, bridging bar 8 was inclined upwardly, thereby can avoid reinforcing bar 10 landings.Shown in Figure of description 4 and 5, when suspender is in discharge position, by cylinder 4 successively drive sub 5, pivoted arm 6, hexagonal axis 2 and cam 7, makes cam 7 rotations and drive bridging bar 8 and rotate around the second bearing pin 81, make bridging bar 8 downward-sloping, thereby reinforcing bar 10 is unloaded.

The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
