1222 connect, and in one embodiment, projection 1211 is connected with vertical portion 1222 by multiple screws 4 and multiple bearing pins 5,
Wherein, bearing pin 5 is between screw 4 adjacent two-by-two.It is arranged at intervals using screw 4 and bearing pin 5 (alternatively referred to as safe bearing pin)
Mode further increase connection between fag end seat 122 and column 121, in the case that screw 4 fails, fag end seat
Still there is bearing pin 5 to be attached between 122 and column 121, prevent fag end seat 122 from splitting away off.In one embodiment,
As shown in figure 3, projection 1211 is connected with vertical portion 1222 by a screw 4 two-by-two and a bearing pin 5, being connected using this mode can
Ensure the stable safety of fag end seat 122, the i.e. conduct of bearing pin 5 of two screws 4 and fag end seat in the case of to be failed in screw 4
Redundancy Design, certainly, in other embodiments, the screw 4 and bearing pin 5 of other numbers are may also set up, i.e. screw 4 can be set to 3
It is individual, 5 or other, be not particularly limited herein.
As shown in Fig. 2 being connected to fag end seat 122 in the both sides of the side wall of column 121, the other end of steel wire rope 123 is successively
Around movable pulley 6 and fixed pulley 7, fixed pulley 7 is located at the top of movable pulley 6, and in one embodiment, fixed pulley 7 is provided with
Two steel wire rope grooves, two steel wire ropes of the side wall of column 121 bypass same fixed pulley 7, i.e. one end of steel cable
It is fixed on the fag end seat 122 in left side, its other end bypasses the movable pulley 6 in left side and the steel wire rope in the left side of fixed pulley 7 successively
Groove, and the other end of steel cable connects with balancing weight.One end of second steel wire rope is fixed on the fag end seat on right side
On 122, its other end bypasses the movable pulley 6 on right side and the steel wire rope groove on the right side of fixed pulley 7, and second steel wire rope successively
The other end connect with balancing weight.
In one embodiment, the guide rail (alternatively referred to as vertical direction guiding rail) of vertical direction is provided with the side wall of column,
Slided on guide rail and be provided with sliding block 8, the pedestal 9 for installing mechanical arm 130 is fixedly installed on sliding block 8.In this implementation
In example, pedestal 9 and sliding block 8 are integrally formed, are moved by sliding block 8 on guide rail to realize that pedestal 9 moves on guide rail, so as to real
Existing mechanical arm 130 moves up and down, and in the present embodiment, movable pulley 6 connects with sliding block 8, specifically, in sliding block 8 and pedestal 9 one
Projection contiguous block 10 above the part of body shaping, contiguous block 10 connects with two movable pulleys 6.In this embodiment, it is
Enable mechanical arm 130 still in a certain height of column 121, balancing weight is connected to the other end of steel wire rope 123, its
In, balancing weight can slide in interior guide rail (weight guide), and steel wire rope 123 bypasses movable pulley 6, and mechanical arm 130 passes through pedestal 9
Connect with contiguous block 10 with movable pulley 6, so as to realize the weight of the weight balancing mechanical arm 130 by balancing weight, so as to realize
Sliding block 8 can stably be in a certain position.Further, under electric model, operator, which operates motor, makes its rotation, motor
Drive fixed pulley 7 rotate, fixed pulley 7 slides up and down movable pulley 6 by steel wire rope, movable pulley 6 with movable slider 8 on guide rail on
Lower slider, so as to realize that mechanical arm 130 moves up and down, when mechanical arm 130 moves up, balancing weight is on weight guide under phase
Slide, when mechanical arm 130 moves down, balancing weight slides on weight guide in phase.When manual hand manipulation's mechanical arm 130
When moving up and down, due to the weight of the weight balancing mechanical arm 130 of balancing weight, operating personnel can operate machine by the power of very little
The vertical upgrading of tool arm 130.Additionally, by movable pulley system, the weight (weight of 1/2 mechanical arm needed for balancing weight is reduced
Amount), reach mitigate operation chassis quality effect.Meanwhile using the design of double-steel wire rope, when a wherein steel wire rope failure
, another steel wire rope still ensure that the demand of normal work, further increases the stability of the operation chassis of the present invention.
Further, multiple lightening grooves 11 are offered on column 121, it can not influence the stability of column 121
Under the premise of further mitigate operation chassis weight.
