Abstract

The utility model discloses a hoisting arm of a crane with a stress-enhancing structure, which comprises a hoisting arm and a telescopic rod movably installed in the hoisting arm; the telescopic rod and the hoisting arm are provided with corresponding adjustment holes, and the A fixing pin is installed in the adjustment hole; it is characterized in that it also includes a reinforcing structure installed on the boom. The utility model enhances the strength of the boom port through the arrangement of the reinforcing structure and the retaining ring to prevent it from being broken due to the large force, improves the force, prolongs the service life, and reduces the hidden danger of safety; , so that the lifting force of the hydraulic cylinder is dispersed through the support plate, so as to reduce the single-point force of the boom and avoid the deformation of the boom caused by excessive single-point force.

Description

Crane boom with stress enhancing structure

Technical Field

The utility model relates to a loop wheel machine field specifically indicates a loop wheel machine davit with reinforcing atress structure.

Background

At present, many hydraulic cranes comprise telescopic rods with suspension arms arranged in the suspension arms and connecting blocks arranged at the bottoms of the suspension arms and connected with hydraulic cylinders; when the telescopic rod is used for lifting an object after being extended, the whole stress of the suspension arm is increased, particularly the port of the suspension arm is influenced by the gravity of the object, most of downward force of the telescopic rod acts on the port of the suspension arm, and when the suspension arm is jacked by a hydraulic cylinder in a matching manner, the suspension arm also plays a supporting role by the connecting point of the port and the telescopic rod, so that the port of the suspension arm is easy to break due to insufficient strength, safety accidents such as object falling and the like are caused, and the suspension arm cannot be used continuously; simultaneously when through hydraulic stem jacking davit, its jacking point is used in connecting block department, and the stress point of davit also is in the installation department of connecting block, and the stress point is comparatively concentrated, and the davit is easy to produce the deformation because of the atress to lead to unable normal use. Therefore, the crane boom with the stress enhancing structure is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problems and providing a crane boom with a reinforced stress structure.

In order to achieve the above purpose, the utility model provides a crane boom with a structure for enhancing stress, which comprises a boom and a telescopic rod movably arranged in the boom; the telescopic rod and the suspension arm are provided with corresponding adjusting holes, and fixing pins are installed in the adjusting holes; it is characterized by also comprising a reinforcing structure arranged on the suspension arm.

Further preferably, the additional strengthening contains the layer board of installing in the davit bottom and installs the protective shroud at davit one end port department, the fixed block is installed to the davit other end.

Further preferably, the bottom of the supporting plate is provided with a connecting block.

Preferably, the top of the suspension arm is further provided with a reinforcing column, the reinforcing column is provided with a connecting plate, and two ends of the connecting plate are respectively and fixedly connected with two ends of the suspension arm.

The utility model, through the arrangement of the reinforcing structure, the strength at the end opening of the suspension arm is enhanced through the protective ring, the suspension arm is prevented from being broken due to larger stress, the stress is improved, the service life is prolonged, and the potential safety hazard is reduced; through the arrangement of the supporting plate, the force generated when the hydraulic cylinder is jacked is dispersed through the supporting plate, so that the single-point stress of the suspension arm is reduced, and the deformation of the suspension arm caused by overlarge single-point stress of the suspension arm is avoided.

Detailed Description

The crane boom with the stress enhancing structure according to the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-3, a crane boom with a stress-enhancing structure of the present embodiment includes a boom 1 and an expansion link 2 movably installed in the boom 1; the telescopic rod 2 and the suspension arm 1 are provided with corresponding adjusting holes 3, and fixing pins 4 are installed in the adjusting holes 3; it is characterized by also comprising a reinforcing structure 5 arranged on the suspension arm 1; through additional strengthening 5's setting, 1 intensity of reinforcing davit and atress degree improve life, reduce the potential safety hazard.

Further, referring to fig. 1-2, the reinforcing structure 5 comprises a supporting plate 51 mounted at the bottom of the boom 1 and a retainer 52 mounted at one end port of the boom 1, and the other end of the boom 1 is mounted with a fixing block 6; the strength of the port of the suspension arm 1 is enhanced through the guard ring 52, the suspension arm is prevented from being broken due to large stress, the stress of the suspension arm is improved, the service life is prolonged, and potential safety hazards are reduced; through the arrangement of the supporting plate 51, the force generated when the hydraulic cylinder is jacked is dispersed through the supporting plate 51, so that the single-point stress of the suspension arm 1 is reduced, and the deformation of the suspension arm 1 caused by overlarge single-point stress is avoided; the suspension arm 1 is installed on the crane through the arrangement of the fixed block.

Further, referring to fig. 1-2, the bottom of the supporting plate 51 is provided with a connecting block 7; connect the pneumatic cylinder through connecting block 7, the connecting block is moved in the top during hydraulic cylinder jacking, and connecting block 7 will receive the power transmission of jacking to layer board 51 and disperse, reduces the single-point atress to improve whole atress degree.

Further, referring to fig. 1 and 3, a reinforcing column 8 is further installed at the top of the suspension arm 1, a connecting plate 9 is installed on the reinforcing column 8, and two ends of the connecting plate 9 are respectively and fixedly connected with two ends of the suspension arm 1; the top of the suspension arm 1 is provided with the reinforcing column 8 and the connecting plate 9, and the two ends of the suspension arm 1 are connected through the connecting plate 9, so that the overall strength of the suspension arm 1 is improved, and the bending deformation caused by stress is avoided.
