Bolt is removably connected to middle position on the outside of two long sides of the rectangular frame 311 of pedestal 1, and top is dismountable by bolt
It is connected to the middle part or middle and upper part position of main vertical rod body 21.The brace may also set up 4 or other quantity, with further
Improve the stability of main vertical rod 2.Preferably, the brace can use rectangle or circular hollow steel pipe manufacturing.
As shown in Figure 1 and Figure 4, the pedestal 3 includes the base body 31 and cylinder of generally rectangle shape plate-like structure
The lower vertical rod 32 of shape.In the present embodiment, the base body 31 is formed by rectangle hollow steel-pipe welding, to improve base body
31 intensity, the internal welding of rectangular frame 311 of base body 31 are connected to the overall a plurality of reinforcement in " soil " font or " well " font
Muscle 312.The lower vertical rod 32 is vertically arranged in close to the side of the short side of rectangular frame 311, and its object is to avoid base body
The position of the opposite side of 31 middle parts and remote lower vertical rod 32, to set counterweight to leave the space of abundance on base body 31.
Preferably, vertical rod 32 is welded on the infall of reinforcement 312, to obtain maximum bonding strength.The top of lower vertical rod 32 is provided with
For connecting the 4th ring flange 34 of main vertical rod 2.To improve base body 31 to the support strength and stability of lower vertical rod 32, square
The support beam for supporting lower vertical rod 32 is also welded with two long sides of shape framework 311 and a short side of close lower vertical rod 32
33, the upper end of the support beam, which tilts, is hooked and is welded on the lower middle part of vertical rod 32 or middle and upper part.Support beam 33 is in base body 31
On arrangement, be also on base body 31 set counterweight leaving space.Preferably, the support beam
33 can use the materials such as angle bar, steel pipe or reinforcing bar to make.Preferably, to improve the durability of pedestal 1, counterweight is reduced to base
Abrasion caused by seat body 31 is damaged, and the backing plate 5 of rectangular configuration, the width of the backing plate 5 can also be set on base body 31
Degree is equal to or slightly less than the bond length of the rectangular frame 311 of base body 31, and its length is equal to or slightly less than lower vertical rod 32 to square
The distance of the side short side farther out of shape framework 311.Backing plate 5 can be placed directly in the rectangular frame 311 of pedestal 1 when using loop wheel machine
On, can also it use screw or bolt to be directly fixedly connected on the rectangular frame 311 of pedestal 1.
It is as shown in Figures 1 to 4, removable by 4 bolts between the turning arm 1 and main vertical rod 2 as a kind of embodiment
Be connected first flange disk 11 and the second flange disk 22 unloaded is removable by 4 bolts between the main vertical rod 2 and pedestal 3
Be connected the 3rd ring flange 23 and the 4th ring flange 34 unloaded.User, can be vertical to turning arm 1, master when using this loop wheel machine
3 components of bar 2 and the grade of pedestal 3 carry out Assembling, it is only necessary to which 8 bolts can complete assembly, simple and convenient.Loop wheel machine uses
After the completion of, disassembling for loop wheel machine can be completed by pulling down 8 bolts, and 3 after disassembling component is highly convenient for transport and carried.
As another embodiment, as shown in figure 5, after this loop wheel machine is completed, pedestal 3 is placed in strong ground
On, the counterweight using the supporting leg 6 of the vehicles such as lorry, trailer or Other Engineering machinery as this loop wheel machine, directly it is pressed on the pad of pedestal 3
On plate 5, the fixation of the pedestal 3 of this loop wheel machine is realized.In the prior art, to improve the stability and Lifting Capacity of loop wheel machine, generally need
Counterweight is carried out to loop wheel machine pedestal, the maximum Lifting Capacity positive correlation of the weight of counterweight generally with loop wheel machine, this is to cause existing skill
The main reason for loop wheel machine heaviness of art is not portable.This loop wheel machine is provided with what is be used cooperatively with vehicle or the supporting leg of engineering machinery 6
Backing plate 5, the counterweight that supporting leg 6 is directly born against on the backing plate 5 of pedestal 3 as loop wheel machine can be used in lifting operation, so as to keep away
The drawbacks of having exempted to need to be separately provided counterweight for loop wheel machine in the prior art.
One kind as present embodiment is improved, and two braces 4 can not also be installed, so that being left more on pedestal 3
Big counterweight space, using directly regarding a pressure wheel of vehicle or engineering machinery as counterweight on backing plate 5 during loop wheel machine.
Loop wheel machine described in present embodiment carries out operation using following hanging method:
(1)Complete loop wheel machine component(That is turning arm 1, main vertical rod 2 and pedestal 3)Assembly;
(2)Loop wheel machine is vertically placed to strong ground, by vehicle or the supporting leg of engineering machinery 6 or pressure wheel loop wheel machine pedestal 3 pad
Counterweight is used as on plate 5;
(3)Start lifting operation after the completion of, remove counterweight, disassemble loop wheel machine.
As the third embodiment, backing plate 5 is not provided with pedestal 3, multiple be used for is set on the base body 31 of pedestal 3
Vertical insertion screw pedestal 3 being fastened on vehicle or engineering machinery.During using loop wheel machine, the spelling of loop wheel machine is completed first
Dress, then bolt is passed through to the vertical insertion screw of base body 31, be arranged on the compartment of vehicle or engineering machinery, vehicle frame or
The screw to match at the solid firm position such as chassis, which combines, to be fixed, it is achieved thereby that pedestal 3 and vehicle or the company of engineering machinery
Fixation is connect, can then carry out lifting operation.Present embodiment is separately provided counterweight again without for loop wheel machine.
In a practical application, the pedestal using 3 × 5 centimeter rectangular hollow steel pipes weld, base size be 70 ×
50 × 50 centimetres(Length × width × height), main vertical rod is using 12 centimetres of diameter, high 180 centimetres of hollow steel pipe, and turning arm is using straight
The hollow steel pipe welding of 6 centimetres of footpath, spread length are 250 centimetres, 6 millimeters of wirerope diameter, 10 meters of length.After tested, loop wheel machine is conducted oneself with dignity
Less than 150 kilograms, maximum lifting weight is more than 500 kilograms.This loop wheel machine is simple for structure, is easy to carry about with one, simple to operate, and function is complete
Kind, Lifting Capacity is strong, is especially suitable for wild environment use.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
