Movable crane with height capable of being adjusted conveniently

Abstract

The invention discloses a movable crane with the height capable of being adjusted conveniently. The movable crane comprises a stand column, a jacking rod is arranged at the bottom of the stand column in an embedded mode, protrusions are connected to the lower portion of the stand column, a support beam is connected to the jacking rod, a circular ring is arranged in the middle of the support beam, the two sides of the lower portion of the support beam are each provided with connecting blocks which are connected to a walking frame, an annular protrusion is arranged on the upper portion of the stand column, a gearbox is connected to the upper end of the annular protrusion, a telescopic rod is further connected to the left side of the gearbox, a cantilever beam is connected to the other end of the telescopic rod, a counterweight body is arranged on the left side of the lower portion of the cantilever beam, a support table is arranged on the top of the stand column, reinforcing plates are arranged on the outer sides of the support table, and a hydraulic support is arranged on the support table and comprises hydraulic cylinders and lower supports. The movable crane with the height capable of being adjusted conveniently has the advantages of being high in structural strength, large in bearing capacity, novel in design, convenient to use, convenient to reverse, safe and reliable.

Description

technical field [0001] The invention relates to a crane, in particular to a mobile crane with convenient height adjustment. Background technique [0002] Cantilever cranes, also known as cantilever cranes, have the advantages of convenient operation, flexible rotation, and large working space. They are energy-saving and efficient material handling equipment. With the continuous development of the economy, cantilever cranes have been widely used in economic construction. The use environment is mostly on the ground or at a position with a low height from the ground. The cantilever is rotated by pulling the suspension ring at the front end of the cantilever. The height cannot be adjusted, which limits the scope of use of the cantilever crane, and cannot meet the requirements of more workers. Although some lengths can be adjusted by adjusting the position of the bolt on the bolt hole, the strength of the structure itself is weakened, and the adjustment is inconvenient; at the sa...

[0002] Cantilever cranes, also known as cantilever cranes, have the advantages of convenient operation, flexible rotation, and large working space. They are energy-saving and efficient material handling equipment. With the continuous development of the economy, cantilever cranes have been widely used in economic construction. The use environment is mostly on the ground or at a position with a low height from the ground. The cantilever is rotated by pulling the suspension ring at the front end of the cantilever. The height cannot be adjusted, which limits the scope of use of the cantilever crane and cannot meet the requirements of more workers. Although some can adjust the length by adjusting the position of the bolt on the bolt hole, it weakens the strength of the structure itself and is inconvenient to adjust; at the same time, the crane It often needs to be moved, so the bottom is often equipped with a traveling mechanism. The existing crane traveling mechanism includes supports fixed on both sides of the lower end of the door seat. The supports are directly connected to the walking frame, and the walking frame is equipped with traveling wheels. The traveling mechanism can run safely and smoothly on parallel straight tracks. When there is a cross track and the track needs to be changed, the track change cannot be quickly realized, which reduces the working efficiency and limits the scope of use of the crane.
