Abstract

The utility model provides a lifting light tower crane for building construction, which can lift an entire machine simultaneously along with the rise of floors. The utility model comprises a tower top, a tower body, a crane boom perpendicularly correspondingly movably hinged with the tower body, a balance arm and a winding lifting device mounted on the balance arm. The utility model is characterized in that a tower seat is composed of an upper part sleeve frame, a lower chassis and a connection stay rod in the middle. The bottom of the chassis is also provided with a ballast mechanism connected with the chassis. The tower crane has the advantages of a few use material, light weight, low expense and good safety of construction operation.

Description

Light tower crane

The utility model belongs to lifting machinery, particularly a kind of be used for building constructions, its complete machine can with the synchronous lifting of floor with the lift-type light tower hoist.

Present high-rise building tower crane for building all is mounted on the vacant lot that its side is close to, and separate with the tower seat at the certain altitude position that cover is erected at body of the tower.For adapting to the needs that building progressively raises, by accessory equipment, aerial work is increased body of the tower and lengthening crane arm.Its major defect is big with the material amount, and the expense height is dangerous, and the ballast at tower seat place is strengthened, and it is bothersome to take a lot of work.

The purpose of this utility model provides a kind of being contained in the building, whole tower crane can with the floor lifting with the lift-type light tower hoist, have that body of the tower is low, crane arm short, few with material, expense is low and the advantage of safety is installed, and has overcome the shortcoming of prior art.

For achieving the above object, the technical solution of the utility model is: this tower crane comprises cat head, and body of the tower becomes vertical with the body of the tower both sides and correspondingly is set to moveable hinge bonded assembly crane arm and equilibrium arm, and the elevator jack up unit of top loading.Be characterized in the tower seat by top stock, bottom chassis and between strut connect and compose.Below the chassis, also be provided with ballast mechanism.

Stock and body of the tower are adaptive, by foursquare up and down framework and between 4 main limbs and the connection stretching between main limb be solidly connected and constitute.Body of the tower can tighten up and be contained in the stock, between framework and the body of the tower idler wheel mechanism is housed up and down.

The chassis is and the cooresponding square of stock, is fastenedly connected by attaching parts by 4 pull bars and 4 feets to constitute.

Strut is identical 4 long struts and 4 identical short struts, its two ends respectively by attaching parts with 4 jiaos of framework and the feet place on chassis are fastenedly connected up and down.

Ballast mechanism below the chassis is followed successively by lacing wire from top to bottom, regulates bolt sleeve and hook bolt, captives joint with the chassis in the upper end of lacing wire, and the hook end of hook bolt is connected with the building basic fixed, also can captive joint with other firm position of building body.

The utility model compared with prior art has following advantage:

1. can be installed in the building of building because of tower crane and complete machine can progressively raise and lifting is simultaneously shortened crane arm and equilibrium arm with floor, body of the tower greatly reduces, the descending at double with material, expense and weight of tower crane;

2. cover is configured to the tower seat, and mounting height reduces significantly, when connecing high body of the tower, has reduced aerial work, and safety is good.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1: the utility model is contained in the topology view of ground floor

Fig. 2: the A-A cutaway view among Fig. 1

Fig. 3, Fig. 4, Fig. 5: the utility model is with the topology view of floor rising complete machine lifting process.

Below in conjunction with embodiment (accompanying drawing) the utility model is further described: be provided with in the joint of cat head 2 and body of the tower 10 with moveable hinge bonded assembly crane arm 35, equilibrium arm arm 8 and lifting support 4, its external end head is connected with the upper end of cat head 2 by stay cord 3, crane arm 35 and equilibrium arm 8 on a horizon vertical with body of the tower 10, the corresponding installing in front and back.The elevator jack up unit is made of the winch 6 that is connected by derrick line 5, guide wheel 1, the suspension hook 32 that has the crane carriage 34 of roller and have a pulley 33.Winch 6 and counterbalanced weight 7 are contained on the external end head of equilibrium arm 8, and crane carriage 34 is contained on the wheel track of crane arm 35.Body of the tower 10 is connected support 25 standard knots that constitute by body of the tower master limb 24 and connects to form with body of the tower.The tower seat is made of stock, chassis and strut 13,18.Stock is fastenedly connected institute and is constituted by the support 15 that is connected of 14 of upper frame 11, underframe 17 and middle main limb 14 and main limbs, and matching with body of the tower 10 is contained in tower seat top.Between the framework up and down 11,17 of stock and the body of the tower 10 guide roller mechanism 26 is housed.The chassis is fastenedly connected by attaching parts 12 by 4

pull bars

22 and 4 feets and constitutes, and feet is made of the supporting baseplate 21 and the cover support swivel nut 20 in the above of upright studdle 19, bottom.Framework 11,17 and chassis are cooresponding square up and down up and down, the two ends of 4

long struts

13 and 4 short struts 18 by attaching parts 12 respectively with 4 feets on chassis and up and down 4 jiaos of

framework

11,17 be fastenedly connected, and be evenly distributed on every side, correspondence up and down.Ballast mechanism is made of lacing wire 27, adjusting bolt sleeve 28 and hook bolt 29, captives joint with the chassis in the upper end of lacing wire 29, and its lower end is connected with the upper end of hook bolt 29 by regulating bolt sleeve 28, and its gib head end is captiveed joint with building basis 30 or building body 31.

The utility model with the process that floor raises the complete machine lifting is: 1, after building second layer floor has been laid (body of the tower is reserved the lifting hole on every side), put chock 23 well in body of the tower 10 bottoms, between the upper end of winch 6, hangers 36 and lifting support 4, install additional and connect pulley M and halliard L, unclamp stay cord 3, crane arm 35 and equilibrium arm 7 are put down, its external end head is dropped on make to support (Fig. 3) on the floor; 2, unclamp the lacing wire 27 below pin (lifting beam) 16 and the chassis of being connected and fixed between body of the tower 10 and the stock, folding removes 13,18 times coupling ends of strut, stock and chassis risen on two floors in statu quo install, chock 23, spreading lacing wire 27 connects (Fig. 4) with hook bolt 29; 3, with bottle gouard moved by hands or self lifting appliance body of the tower 10 is promoted on the two floor plates, installs set pin 16, two arms are given rise to the home position fasten stay cord 3, can begin lifting operation (Fig. 5).After, during the lifting complete machine, repeat said process and get final product again.
