Description

Tower crane with traveling mechanism

technical field

The invention belongs to the technical field of construction engineering and relates to a tower crane with a traveling mechanism.

Background technique

Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". Raw materials for construction. Tower crane is an indispensable equipment on the construction site.

The function of the tower crane tip is to bear the upper load from the jib stay rope and the balance jib stay rope, and transmit it directly to the tower body structure through the turntable through the structural components such as the slewing tower, turntable, and seat. The top of the self-elevating tower has a truncated cone column type, a forward or backward inclined truncated cone column type, a herringbone frame type and a diagonal brace type. All upper slewing tower cranes need to be equipped with a balance weight, whose function is to support the balance weight to form the balance moment required by the design in the opposite direction to the lifting moment. In addition to the balance weight, a lifting mechanism is often installed at its tail. The reason why the hoisting mechanism is placed at the end of the balance arm together with the counterweight is that, on the one hand, it can play a part of the role of counterweight, and on the other hand, it can increase the distance between the rope drum and the guide wheel at the tip of the tower, so as to facilitate the winding of the wire rope and avoid the occurrence of Rope phenomenon. The amount of balance weight is inversely proportional to the length of the balance arm, and there is a certain proportional relationship between the length of the balance arm and the length of the boom. The balance weight is quite considerable. Light tower cranes generally require at least 3 to 4 tons, and heavy tower cranes require nearly 30 tons.

Tower cranes can be divided into mobile tower cranes and fixed tower cranes. Mobile tower cranes can be divided into four types: track type, tire type, car type, and crawler type according to different traveling devices. The track-type tower crane is fixed on the walking chassis and can run on a specially designed track. It has good stability and high work efficiency, so it is widely used in construction and installation projects. Tire-type, car-type and crawler-type tower cranes have no track device and are easy to move, but they cannot walk with a load and have poor stability.

Fixed tower cranes are divided into two types: attached self-elevating type and internal climbing type according to different installation locations. The attached self-elevating tower crane can rise with the rise of the building, which is suitable for high-rise buildings. It bears the horizontal load transmitted by the tower crane and is easy to attach, but it takes up a lot of steel for the structure; the internal climbing tower crane climbs in the elevator shaft and stairwell inside the building with the help of a set of brackets and a lifting system. The jacking is more cumbersome, but The occupied structure uses less steel and does not need to install foundations, and all self-weight and loads are borne by the building.

Regardless of whether it is a mobile tower crane or a fixed tower crane, either the bottom of the tower crane is fixed to the ground to achieve load bearing, or the building completes the load bearing, so the stability needs to be improved. Especially mobile tower cranes cannot walk with a load, which greatly restricts the application and development of mobile tower cranes.

When the guide wheel brake 43 returns to the initial state , the guide wheel brake 43 is disengaged from the track 31, and the guide wheel 41 and the track 31 are in a movably connected state.

As shown in FIG. 5 , the bottom of the tower crane 100 is also provided with a balance mechanism 5 that can balance the force of the tower crane 100 in the vertical direction and/or horizontal direction, so as to ensure the stability and safety of the tower crane 100 . Specifically, the balance mechanism 5 includes a counterweight assembly 51 and a balance bar assembly 52 respectively arranged on the upper and lower sides of the support platform 102, and the balance bar assembly 52 is pressed on the guide wheel support bar 103 and connected with the guide wheel support bar 103 is fixedly connected, and the balance bar assembly 52 is that the gravity of the tower crane 100 can be evenly distributed to the guide wheel support bar 103, so as to be evenly distributed on each track 31, and the counterweight assembly 51 can balance the gravity of the left and right and increase the weight of the tower crane 100. The effect of gravity at the bottom makes the center of gravity of the tower crane 100 drop, improving the stability of the tower crane 100 .

In this embodiment, the counterweight assembly 51 includes two counterweights 53 arranged symmetrically along the axis of the tower crane 100, the counterweights 53 are fixed on the upper surface of the support platform 102, and the balance bar assembly 52 includes A plurality of balance bars 54 parallel to each other and perpendicular to the guide wheel support bar 103, the balance bar 54 is fixedly connected with the lower surface of the support platform 102 and the guide wheel support bar 103 respectively, and the balance bar 54 is preferably perpendicular to the guide wheel support bar 103 intersect.
