Including channel-section steel support, connecting plate and round steel, channel-section steel support afterbody welding round steel, the head welded connection board that the channel-section steel held in the palm, the connecting plate top is equipped with the through-hole, installs the otic placode on the structure, the otic placode symmetry sets up in round pin axle top both sides, is equipped with the through-hole that corresponds with the connecting plate on the otic placode, the connecting plate passes through spring catch swing joint on the otic placode. The utility model has the advantages that: the structure is simple, the processing is easy, and the installation is easy; can rotate freely, and the pin shaft is easier to take out.
Description
Technical Field
The utility model relates to an auxiliary device is torn open to round pin axle ann belongs to tower machine and dismantles technical field.
Background
The hinge pin is used as a fastener, is mainly used for the hinged parts of two parts, is reliable in work and convenient to disassemble, but as the tower crane is installed and disassembled in high-altitude operation, in the design process of a balance arm of a swing arm type tower crane, the situation that the lower side connecting hinge pin cannot support in the disassembling process is found, safety accidents can be caused, and difficulty is brought to the installation of the hinge pin, particularly large-tonnage tower cranes, the weight of the hinge pin is large, and trouble is brought to high-altitude installation.
Disclosure of Invention
In order to overcome the weak point of above-mentioned prior art, the utility model provides an auxiliary device is torn open in round pin axle ann, supplementary safe installation dismantles the round pin axle.
The utility model discloses a realize through following technical scheme: the utility model provides an auxiliary device is torn open in ann of round pin axle which characterized in that: including channel-section steel support, connecting plate and round steel, channel-section steel support afterbody welding round steel, the head welded connection board that the channel-section steel held in the palm, the connecting plate top is equipped with the through-hole, installs the otic placode on the structure, the otic placode symmetry sets up in round pin axle top both sides, is equipped with the through-hole that corresponds with the connecting plate on the otic placode, the connecting plate passes through spring catch swing joint on the otic placode.
The height of the round steel is smaller than the diameter of the pin shaft.
The channel steel support and the connecting plate can move up and down around the spring pin.
The two sides of the spring pin are provided with vertical pins which are clamped into the spring pin to place the spring pin and draw out the lug plate.
The length of the channel steel support is larger than or equal to that of the pin shaft.
The utility model has the advantages that: the structure is simple, the processing is easy, and the installation is easy; can rotate freely, and the pin shaft is easier to take out.
Drawings
The invention will be further explained below with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a channel steel support; 2. a connecting plate; 3. round steel; 4. a structural member; 5. an ear plate; 6. a pin shaft; 7. a spring pin; 8. and (6) standing the pin.
Detailed Description
As shown in figure 1, the auxiliary device for installing and detaching the pin shaft is characterized in that: including channel-section steel support 1, connecting plate 2 and round steel 3, 1 afterbody welding round steel 3 of channel-section steel support, 1 head welding connection board 2 of channel-section steel support, 2 tops of connecting plate are equipped with the through-hole, install otic placode 5 on the structure 4, 5 symmetries of otic placode set up in 6 top both sides of round pin axle, are equipped with the through-hole that corresponds with connecting plate 2 on the otic placode 5, connecting plate 2 passes through spring catch 7 swing joint on otic placode 5.
The height of the round steel 3 is smaller than the diameter of the pin shaft 6. The channel steel bracket 1 and the connecting plate 2 can move up and down around the spring pin 7. Both can guarantee that the round pin axle 6 dismantled can not the roll-off, can act as the handle again, when round pin axle 6 need be taken out, has twisted round steel 3 with the hand, and auxiliary device is torn open in upset round pin axle ann, takes out round pin axle 6.
The two sides of the spring pin 7 are provided with vertical pins 8, and the vertical pins 8 are clamped into the spring pin 7 to place the spring pin 7 and scratch the ear plate 5. The length of the channel steel support 1 is larger than or equal to that of the pin shaft 6.
