Description

Technical Field

[0001] The utility model relates to the field of hoisting, in particular to an adjustable waist rope frame structure. Background Art

[0002] Crawler cranes are widely used in construction, wind power installation and other fields. With the rapid development of my country's science and technology and economy, the hoisted objects have the characteristics of heavy weight and large volume. At the same time, there are new requirements for the lifting height. The boom length and weight of crawler cranes are therefore increasing, and a waist rope needs to be installed to reduce the deformation of the main arm.

[0003] The waist rope is a component selected when the boom is raised. When the boom is raised for an extra-long boom (about 180 meters or more), the waist rope is generally used. The waist rope can reduce the bending degree of the main boom and prevent the main boom from being damaged due to excessive deflection. The number of waist ropes can be selected according to needs. When in use, just connect the two ends of the waist rope to the pull plate and the boom respectively. The boom, also known as the crane arm or the jib, is composed of different arm sections. The width of different arm sections varies. It is mainly used to lift or move the target to a specified position.

[0004] Most of the current waist rope racks are welded from steel pipes with a fixed length that cannot be changed. They cannot adapt to arm sections of different spans and often require waist rope racks of different sizes, which increases production costs. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the prior art, the utility model provides an adjustable waist rope frame structure, which can change the width of the waist rope frame by adjusting the fixed position of the pin shaft, so that a set of waist rope frames can adapt to the arm lifting requirements of multiple working conditions, thereby achieving the purpose of reducing costs and increasing efficiency.

[0006] Technical solution: The utility model is an adjustable waist rope frame structure, which is characterized by: adopting a balance beam structure, the balance beams of the waist rope frame are connected by pin shaft 1 and pin shaft 2, pin shaft 1 corresponds to hole 1 and hole 2, pin shaft 2 corresponds to hole 3 and hole 4, and the pin shafts are inserted into different holes to fix the position and adjust the extension and retraction of the balance beam.

[0007] Among them, the pin shaft one is inserted into the hole one, the pin shaft two is inserted into the hole three, and the balance beam forms a span of one.

[0008] Among them, the pin shaft one is inserted into the hole two, the pin shaft two is inserted into the hole four, and the balance beam forms a span of two.

[0009] Wherein, the balance beam is connected with the arm section.

[0010] Wherein, the balance beam and the boom section are installed on a crawler crane.

[0011] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the utility model changes the width of the waist rope frame by adjusting the position of the pin shaft connection and fixation, so that the staff can adjust the width of the waist rope frame by changing the position of the pin shaft to make the balance beam retract and retract, so that one set of waist rope frame can adapt to the boom requirements of multiple working conditions, achieving the purpose of reducing costs and increasing efficiency. It can be flexibly applied to boom sections of different spans, and there is no need to assemble multiple sets of waist rope frames to adapt to boom sections of different spans, thereby reducing production costs.

[0015] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0016] The adjustable waist rope frame structure of the utility model adopts a balance beam structure. The balance beams of the waist rope frame are connected by a pin shaft 1 5 and a pin shaft 2 6. The pin shaft 1 5 corresponds to a hole 1 and a hole 2 2, and the pin shaft 2 6 corresponds to a hole 3 3 and a hole 4 4. The pin shafts are inserted into different holes to fix the position and adjust the extension and contraction of the balance beam. Among them, the pin shaft 1 5 is inserted into the hole 1, and the pin shaft 2 6 is inserted into the hole 3 3, and the balance beam forms a span of 1. The pin shaft 1 5 is inserted into the hole 2 2, and the pin shaft 2 (6) is inserted into the hole 4 4, and the balance beam forms a span of 2. The balance beam is connected to the boom section. The balance beam and the boom section are installed on a crawler crane.

[0017] The utility model changes the waist rope frame from a steel pipe to an adjustable balance beam, and the balance beams are connected by pins. Hole 1 and hole 2 are respectively the fixed positions of pin 1 5 at span 1 and span 2, and hole 3 and hole 4 are respectively the fixed positions of pin 2 6 at span 1 and span 2. By changing the fixed position of the pin, the balance beam is controlled to be extended and retracted, and the length of the waist rope frame is adjusted to adapt to arm sections of different spans. The scheme is not limited to this connection method, and can achieve adjustment of a larger span range through multi-hole and multi-pin connection.

[0018] The utility model changes the width of the waist rope frame by adjusting the position of the pin shaft connection and fixation, so that the staff can adjust the width of the waist rope frame by changing the position of the pin shaft to extend and retract the balance beam, so that one set of waist rope frames can adapt to the boom requirements of multiple working conditions, thereby achieving the purpose of reducing costs and increasing efficiency. It can be flexibly applied to boom sections of different spans, and there is no need to assemble multiple sets of waist rope frames to adapt to boom sections of different spans, thereby reducing production costs.
