Description

Auxiliary device for mounting and dismounting heavy pin shaft

Technical Field

The utility model relates to an ann tears heavy round pin axle auxiliary device open's technical field, specifically is an ann tears heavy round pin axle auxiliary device open.

Background

In engineering machinery, shaft parts are widely applied. For example, the connection between the tower head and the balance arm and the balance weight arm in the tower crane, and the connection between the arm support and the arm support are applied to shaft parts. When the tower head is connected with the arm support and the balance arm in high altitude, the connecting shaft is generally firstly stored in the shaft support frame and hoisted to the air along with the structural member, and the shaft pulling device is generally required to be used for assisting installation due to the large mass of the shaft during connection. When two connecting pin shafts are placed in the shaft bracket at the same time, the space for installing the shaft puller is insufficient, so that the shaft in the shaft bracket needs to be moved and adjusted, and the space for installing the shaft puller is left. Under the unable operating mode that uses of large-scale hoisting equipment, because the connecting axle overweight manual work can't put the axle to the assigned position, the manual work is removed the transport to the round pin axle and is almost impossible to realize, this just needs a plurality of workman's cooperation installation, and not only consumes a large amount of cost of labor more has very big potential safety hazard like this.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, namely the problems of the prior art, the utility model provides an installation and disassembly heavy type pin shaft auxiliary device, which comprises a tower head, a balance arm and a connecting shaft, wherein the connecting shaft is arranged in a shaft bracket of the tower head;

the chassis includes channel-section steel, location axle, pipe, the board and the side of bending, square pipe welding is between the pipe, the board welding of bending is in the below of pipe, and the board slip joint of bending is on the bearing bracket, the below at the channel-section steel is installed through the location axle to the pipe.

The utility model has the advantages of: the problem of a large amount of artifical bare-handed installations is solved to this scheme ingenious hand capstan winch theory of operation of utilizing after designing, and structural design is light and handy, and manufacturing process is simple, effectively improves tower machine mesoaxis class ann and tears efficiency open, improves the efficiency of construction.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The utility model provides an ann tears heavy round pin axle auxiliary device open, as shown in fig. 1, ann tears heavy auxiliary device open mainly comprises hand winch 1 and chassis 2 two parts. A plurality of hole sites are arranged on the channel steel of the underframe 2, and the hand winch can be arranged on the underframe by using the bolt 3, the washer 4 and the nut 5 according to the use requirements.

As shown in fig. 2 and 9, the chassis 2 is an adjustable chassis, and is composed of the following 5 parts. The upper part of the channel steel 6 is provided with a plurality of hole sites for connecting with a hand winch. A plurality of round holes are formed in the lower portion of the channel steel, and the positioning shaft 7 is inserted and then welded and fixed. Different positioning intervals meet the use requirements of different types of tower cranes. Two round pipes 8 are welded on the bending plate 9, and the round pipes are welded and fixed by a square pipe 10. The bottom adopts the board 9 of bending when using to bend board 9 can just block on the channel-section steel of bearing bracket, and the restriction ann tears heavy round pin axle auxiliary device open and removes, can make the device slide around on bearing bracket simultaneously and can see figure 3. The positioning shaft can be inserted into the inner part of the circular tube to enable the upper part and the lower part of the underframe to be connected into a complete underframe structure, and the circular tube needs to be inserted into different positioning shafts according to different tower types.

As shown in fig. 4, after the tower head 11 is installed [ the connecting shaft 13 is already placed in the shaft bracket during the installation of the tower head ], the balance arm 12 is hoisted to a proper installation position.

As shown in fig. 5, the heavy-duty pin shaft auxiliary device for installation and removal is installed above the shaft bracket of the tower head. Due to the fact that a proper positioning distance is selected, the bending plate can be just fixed on the shaft bracket.

As shown in fig. 6, the pin to be moved is fixed by a wire rope, and the pin is lifted by swinging the hand winch.

As shown in fig. 7, after the pin shaft on one side is lifted, a space for installing the shaft puller 14 is left in the shaft bracket, and the shaft puller is installed to complete the installation of the shaft.

As shown in fig. 8, after the installation of the pin shaft at one side is completed, the position of the shaft puller is adjusted. After the pin shaft is fallen to a proper position by shaking the hand winch, the installation is finished.
