Tower type crane for teaching and exam training

Abstract

The invention discloses a tower type crane for teaching and exam training. The tower type crane for teaching and exam training comprises a balance arm, a cargo boom, a slewing tower body, a driving cab, a tower body and a bottom frame; the cargo boom is fixedly mounted on the front side of the slewing tower body, and the balance arm is fixedly mounted on the rear side of the slewing tower body; and the slewing tower body is connected with the tower body through a slewing mechanism, and the slewing mechanism comprises an upper supporting base, a slewing bearing and a lower supporting base which are sequentially connected from top to bottom; the slewing tower body is fixedly connected to the upper supporting seat, and the lower supporting seat is fixedly connected with the upper end portion of the tower body; and the lower end portion of the tower body is fixedly mounted on the bottom frame, and the driving cab is fixed to the right side of the slewing tower body. The tower type crane for teaching and exam training can allow multiusers to climb the tower body for learning simultaneously, the comprehensive cost is low, and the tower type crane is safe, reliable and convenient to maintain.

Description

technical field [0001] The invention relates to a tower crane; in particular, the invention relates to a tower crane for teaching and training. Background technique [0002] Tower cranes (referred to as tower cranes) are the main construction machinery in the construction field. Due to the high risk of tower crane operation, tower crane driver operation training is listed as a special operation training category. Therefore, during the training process of the tower crane driver, the students must have enough practical training sessions, so the students should be allowed to observe on the tower crane to understand the structure of the tower crane and the mechanism of the safety protection device, and through the guidance of the trainer Hands-on training in high-altitude environments. [0003] Improving the quality of tower crane driver training is an important link to ensure the safe construction of tower cranes. At present, the training of tower crane drivers at home and ab...

AI Technical Summary

Problems solved by technology

At present, the training of tower crane drivers at home and abroad is carried out on construction tower cranes. Since this type of tower crane is specially designed for building construction, its space setting does not consider teaching needs, and cannot provide enough space for trainers to demonstrate operations on the tower , not to allow the coach to sit beside the students to guide the operation

Considering safety factors, construction tower cranes do not allow multiple trainees to climb the tower to observe and learn at the same time, so the training efficiency is low

At the same time, due to the generally high power of construction tower cranes, the use of such tower cranes for teaching and training consumes a lot of energy and the training cost is very high

At this stage, the tower cranes used in the training of tower crane drivers are basically old tower cranes that have been eliminated from the construction site, so there are potential safety hazards

[0004] Chinese patent CN204117488U discloses a teaching demonstration tower crane, which solves the problem that the demonstration is not intuitive due to the inability to combine the operation and control of the tower crane in the teaching work of the tower crane. The tower crane can realize free movement in six directions, and the boom can Free rotation of 360 degrees left and right, the hook can run up and down, and the driving can move forward and backward. Through the mutual control of the operation button, the distribution box and the motor, the working process of the tower crane can be intuitively demonstrated in the teaching

However, this kind of tower crane is only aimed at tower crane disassembly and structural awareness training and cannot train tower crane drivers
