Guardrail with optimized structural on construction machinery

Abstract

The invention discloses a guardrail with an optimized structure on construction machinery. The guardrail with the optimized structure on the construction machinery comprises a fence plate, wherein a flanging edge is shaped in the periphery of the fence plate, supporting railings are fixed on the fence plate, and the two ends of the supporting railings are fixed to the flanging edge. A plurality offlipping positioning brackets are fixed to the flanging edge of the bottom end of the fence plate, the flipping positioning brackets comprise n-shaped connecting frames, rotating shafts are fixed tothe connecting frames in a inserted mode, and T-shaped fixed seats are arranged on the lower side of the connecting frames. The upper ends of the fixed seats are inserted on the rotating shafts in a sleeving mode, shaft sleeves are arranged on the one side of the upper end of each fixed seat in a forming mode, a plurality of inserting grooves penetrating through the inner and outer walls of the shaft sleeves are formed in the shaft sleeves in a forming mode, the outer walls of the rotating shafts are arranged on positioning plates in a forming mode, and the positioning plates are arranged intothe inserting grooves of the shaft sleeves in a inserting mode. The upper ends of the fixed seats, away from the shaft sleeves, are pressed against compression springs, the compression springs are inserted on the rotating shafts in a sleeving mode, and the other ends of the compression springs are pressed against the connecting frames. The guardrail with the optimized structure on the construction machinery can increase the effective passing size without reducing the safety of people, meet the passage space required by most operators, and avoid the waste of manpower and material resources caused by the dismantling of the guardrail.

Description

Technical field: [0001] The invention relates to the technical field of engineering machinery, and more specifically relates to a structure-optimized guardrail on the engineering machinery. Background technique: [0002] At present, construction machinery operation platforms or passages generally have guardrails. The guardrails play a role of safety protection for operators. Due to the large size of some construction machinery, considering the state of mobile transportation, the width of the platform passage is narrow. It is not easy to pass or operate. At present, most of them are disassembled to meet the space requirements. The operation is difficult and the safety is low. The existing fixed guardrail has no possibility of increasing space, and the space is narrow, which affects the passage and maintenance of operators; while the detachable guardrail is inconvenient to operate and requires multiple people to assist in the operation, which is time-consuming and laborious. ...
