Modular combined-type tower crane attached bar with extensive stepless adjustment-type length

Abstract

The invention discloses a modular combined-type tower crane attached bar with extensive stepless adjustment-type length. The modular combined-type tower crane attached bar with extensive stepless adjustment-type length comprises an upper connecting element, a lower connecting element, a screw rod adjustment device, a bar head, a bar tail, first bar bodies and second bar bodies; a first bar body or the combination of two first bar bodies and a second bar body is arranged between the bear head and the bar tail; when a bar body is arranged between the bar head and the bar tail, the bar head and the bar tail are respectively inserted into mounting holes at two ends of the first bar body, and are connected together respectively through a first pin shaft; when the combination of two first bar bodies and the second bar body is arranged between the bar head and the bar tail, two ends of the second bar body are respectively inserted into mounting holes at one ends of the two first bar bodies, and are connected together respectively through two fourth pin shafts; the bar head and the bar tail are respectively inserted into mounting holes at the other ends of the two first bar bodies, and are connected together respectively through a first pin shaft. The modular combined-type tower crane attached bar with extensive stepless adjustment-type length is simple to connect, can be used for improving the stress situations of the attached bar and a tower body at the attached point and the attached part, and is much safe and reliable in operation.

Description

technical field [0001] The invention relates to a tower crane attachment device, which belongs to the tower crane attachment device used in the field of building construction, in particular to a large-range stepless adjustable modularized combined tower crane attachment rod. Background technique [0002] In high-rise construction, tower crane attachment devices are used in large quantities, and such problems often occur: First, the standard attachment devices provided by tower crane manufacturers rarely fully meet the conditions of attachment center distance and attachment point distance in actual use , generally cannot be used directly; secondly, due to the constraints of basement building structure and building environment and other factors, the center distance and attachment point distance of the tower crane attachment device are often different in different construction projects, so the length of the attachment rod needs to be adjusted. The third is that when actually me...

Problems solved by technology

[0002] In high-rise construction, tower crane attachment devices are used in large quantities, and such problems often occur: First, the standard attachment devices provided by tower crane manufacturers rarely fully meet the conditions of attachment center distance and attachment point distance in actual use , generally cannot be used directly; secondly, due to the constraints of basement building structure and building environment and other factors, the center distance and attachment point distance of the tower crane attachment device are often different in different construction projects, so the length of the attachment rod needs to be adjusted. The third is that when actually measuring the distance between the attachment center and the attachment point, measurement errors often occur. Because the adjustment distance of the original attachment rod is relatively small, generally about ±125mm, the length of the prepared attachment rod often cannot meet the site requirements. Installation requirements, sometimes rework phenomenon

The above technologies have not given specific guidance on how to make the structural size of each part of the attachment rod small, convenient for transportation, and improve the stress conditions of the attachment rod itself, the attachment point and the tower body at the attachment point, so as to make the work safer and more reliable.
