Conveying device for tower crane steel structure

Abstract

The invention discloses a conveying device for a tower crane steel structure, and belongs to the technical field of conveying devices. The device comprises a fixing sleeve, two fixing columns are fixedly connected to the inner sidewall of the fixing sleeve, a supporting plate is slidably connected to the two fixing columns, the bottom of the supporting plate is fixedly connected with one end of a thrust spring, the other end of the thrust spring is fixedly connected to the bottom of the inner sidewall of the fixing sleeve, the thrust spring is arranged on the fixing columns in a sleeved mode, and the bottom of the supporting plate and the bottom of the inner sidewall of the fixing sleeve are each both connected with two sliding blocks. When the supporting plate moves downwards, the sliding blocks sliding at the bottom of the sliding plate and the sliding blocks sliding at the bottom of the inner sidewall of the fixing sleeve are driven to get close so that two pairs of magnets repel each other, downward movement of the supporting plate is blocked, the sliding blocks sliding at the bottom of the sliding plate get away from each other while the two pairs of magnets repel each other, a tension spring is stretched, the trend of downward movement of the supporting plate is blocked, and the situation that standard knot parts are loosened due to violent shaking in the conveying process of standard knots is prevented.

Description

technical field [0001] The invention belongs to the technical field of transportation devices, and in particular relates to a transportation device for tower crane steel structures. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as tower crane. An essential piece of equipment on the job site. [0003] At present, the common tower crane steel is spliced ​​into a standard section structure for transportation, so as to be directly spliced ​​on the construction site, but the standard section is prone to vibration during transportation, which makes the parts loose. At the same time, the standard parts are difficult to be fixed and locked, which has certain disadvantages . Contents of the invention [0004] The object of the present invention is to provide a transportation device for tower crane steel structure, so as to solve the problems raised in the above-mentioned background technology. [0005] In ...
