Embodiment
Among Fig. 1: dolly has been suspended on the lead (1), and lead (1) is suspended on the shaft tower (not drawing among the figure) by insulator (35).Bottom in driving cabin (19) is equipped with engine (14), and clutch (12), screw (13), clutch (16) and twisted rope wheel (17) are installed on the rotation axis (not marking on the figure) of engine (14).Connecting plate (20) is arranged at the top of driving cabin (19), in the centre position of connecting plate (20) lifting rope guide ring (5) is installed.The lower end of lifting rope (18) is connected on the twisted rope wheel (17), and lifting rope guide ring (5) is passed in the upper end and hook (4) joins [hook (4) just colludes on lead when the dolly lifting and uses].Arm (22), arm (21), arm (9) and the arm (8) of dismounting flexibly are installed on connecting plate (20), the top of above-mentioned 4 arms is equipped with guide roller (2), guide roller (3), guide roller (6) and guide roller (7) respectively, and above-mentioned 4 guide rollers all are crimped on the lead (1).According to actual needs, nearly 50 centimeters space between two adjacent arms is as the criterion can hold insulator (35).Vertical range up and down between connecting plate (20) and the lead (1) is sitting in the driving cabin with the staff, and the upper half health is exposed at the outside of connecting plate (20), and hand can touch lead (1) and be as the criterion.
Among Fig. 2: the periphery of driving cabin (19) is a rectangle, and there is a bar shaped connecting plate (20) centre of this rectangle, and arm (can't see among the figure) is arranged on the connecting plate (20), and guide roller (2), guide roller (3), guide roller (6) and guide roller (7) are installed on the arm.Above-mentioned 4 guide rollers are crimped on the lead (1).As can be seen from the figure, connecting plate (20) and driving cabin (19) between two limits certain space is arranged up and down operate so that the upper half health of staff exposes driving cabin.
When the staff drives dolly (referring to Fig. 1), clutch (16) is separated, ato unit (14) makes clutch (12) closure more then, and screw (13) promptly begins rotation.The horizontal thrust that produces when screw (13) is during greater than the frictional force between all guide rollers and the lead, and dolly promptly to overtake.The key of problem is the insulator (35) that how to make on the dolly span line.Travel at this supposition dolly right direction in Fig. 1, and guide roller (7) has touched the insulator (35) on the circuit.The staff can at first remove (dismounting principle see Fig. 6 and Fig. 8) together with guide roller (7) from connecting plate (20) with arm (8), and take down the weight of dolly [this moment bear] by other 3 arms from lead (1), start dolly then and make it mobile a little forward.Treat that insulator (35) enters into behind the locus between Fig. 1 guide roller (6) and the guide roller (7) (as shown in phantom in FIG.), the staff recovers to be installed to the origin-location with arm (8) and guide roller (7) again.Then again arm (9) and guide roller (6) are removed from connecting plate (20), dolly is moved forward again, insulator (35) enters into the locus (figure does not draw) between Fig. 1 guide roller (3) and the guide roller (6) again, and then arm (9) and guide roller (6) are recovered to be installed to the origin-location.The rest may be inferred, can make two other guide roller also by insulator (35).By as can be seen above, when crossing insulator (35), the weight of dolly is always born by other 3 arms.Therefore, the quantity of arm can be selected 3 or 4 in the utility model.If be less than 3, then can't crossing insulator, if greater than 4, staff's workload when then having increased dolly by insulator.
The job step that to scheme that dolly in (1) is hanging to from ground on the circuit and dolly is unloaded from circuit below in conjunction with Fig. 3 and Fig. 4 explanation.
Among Fig. 3:,, all guide rollers all must be crimped on the lead (1) for dolly is hanging on the circuit when dolly on the ground the time (not drawing among the figure).For this reason, hook (4) guiding line (1) that the staff can adopt manpower or flinger (existing on the market) will be connected with lifting rope (18) is dished out, and makes hook (4) be suspended on lead (1) by lifting rope (18) and goes up (shown in solid line among the figure).The staff stands in and firmly spurs lifting rope (18) on the ground then, makes hook (4) catch on lead (1) to rising, and turns to position shown in the dotted line among the figure around lead (1).The personnel of proceeding with one's work enter driving cabin (19), and under clutch (12) released state, ato unit (14) at first allows clutch (16) closure then, and twisted rope wheel (17) is rotated towards the take-up direction.The length of taking turns lifting rope (18) between (17) and the hook (4) along with twisted rope constantly shortens, driving cabin (19) promptly rises gradually and [annotates: corresponding with rising, twisted rope wheel (17) is when unwinding direction rotates, the length of lifting rope (18) constantly increases between twisted rope wheel (17) and the hook (4), driving cabin (19) promptly descends gradually, and this is no longer narration below process].When the distance between connecting plate (20) and the lead (1) during less than the length of arm, the staff can take off together with guide roller above-mentioned 4 arms earlier from connecting plate (20), and allow all guide rollers all be crimped on the lead (1), and then arm is reinstalled on the connecting plate (20).Have a fixed gap between guide roller and the lead (1) this moment, and all weight still is added on the hook (4).For this reason, can operate twisted rope wheel (17) driving cabin (19) is descended a little, all be crimped on the lead (1) until all guide rollers.To link up with (4) at last and take off (as shown in Figure 1), and clutch (16) be separated, so that travel ready on the line for dolly from lead (1).
Among Fig. 4: when desiring to make dolly to return ground, all guide rollers all must be taken from lead (1).For this reason, the staff can hang over the hook shown in Fig. 1 (4) on the lead (1), and connect a decoupling device rope (34) [annotate: decoupling device rope (34) should be in the same side of lead (1) with lifting rope (18), and its length stands in can hold on the ground with the staff and is as the criterion] at the other end of hook (4).Under clutch (12) released state, ato unit (14), make clutch (16) closure, operate twisted rope wheel (17) then, make guide roller slightly to rise and and lead (1) between promptly form a fixed gap [annotate: hook this moment (4) is born all weight], can pull down 4 arms and guide roller lifted down from lead (1) from connecting plate (20) and get final product this moment.Operate twisted rope wheel (17) subsequently again, driving cabin parts such as (19) are dropped on the ground gradually.Because hook (4) also hangs on the lead (1), the staff can stand in and firmly spur decoupling device rope (34) on the ground, and hook (4) promptly splits away off from lead (1).Last staff can recover all arms and guide roller to be installed on the connecting plate (20), uses next time to get ready so that be.
Among Fig. 5: adopted with Fig. 1 in identical engine (14), driving cabin (19), connecting plate (20) and arm (22), arm (21), arm (9) and arm parts such as (8), also identical among the numbering of each parts and Fig. 1.Difference is that engine among Fig. 1 (14) drives screw (13) rotation, travels before screw generation thrust forward makes dolly road direction along the line.Then be that engine (14) drives 4 identical power transmission shafts (10) rotation by gearbox (15) and power transmission shaft (11) among Fig. 5, power transmission shaft (10) (does not draw among the figure by gear, can be referring to Fig. 6) drive guide roller again and on lead (1), roll forward, so, guide roller travels before promptly dragging dolly road direction along the line.
Dolly shown in Fig. 5 is hanging to lead (1) to be gone up and makes dolly basic identical from operating process and Fig. 1 that lead (1) turns back to ground from ground.As shown in Figure 3 and Figure 4.
The work schematic diagram of the left view of arm among Fig. 5 (22) and the dismantled and assembled mechanism that matches with it can be referring to Fig. 6.
Below in conjunction with the operating process of Fig. 6, Fig. 7 and Fig. 8 explanation with arm dismounting from the connecting plate.
Among Fig. 6: on connecting plate (20), two identical arms (22) (annotating: also can be regarded as an arm) are installed, guide roller (2) is installed in the top of arm (22) by rotating shaft (23), end in rotating shaft (23) is equipped with driven pulley (24), driving wheel (25) is meshed with driven pulley (24), and links together with power transmission shaft (11) by power transmission shaft (10), plug (28), socket (27).The race of guide roller (2) is crimped on the lead (1).So, engine (14) can pass through power transmission shaft (11), socket (27), plug (28), power transmission shaft (10), driving wheel (25) and driven pulley (24) driving guide roller (2) rotation.Plug (28) is seen Fig. 7 with the A-A section of socket (27).Under the effect of external force, plug (28) can insert in the socket (27) or from socket (27) and extract.In the lower end of two arms (22) arm pin (29) is housed respectively, arm (22) is inserted on the connecting plate (20) by arm pin (29).Arm pin (29) can be pulled up (promptly pulling down) or plugs with arm (22) from connecting plate (20).A cover plate (26) is arranged on arm pin (29), and depression bar (31) is pressed on the upper surface of arm pin (29) (can referring to Fig. 8) by pulley (30) and cover plate (26).The staff with arm (22) with arm pin (29) when connecting plate (20) is pulled up or is plugged, because driven pulley (24), driving wheel (25), power transmission shaft (10) and plug (28) are fixed together with arm (22), therefore, plug (28) is also pulled up or is plugged thereupon.
Among Fig. 7: plug (28) is inserted in the socket (27), and the two coincide together mutually to rely on 4 right-angle sides, and therefore when socket (27) rotated under the drive of power transmission shaft (11), plug (28) promptly rotated thereupon.
Among Fig. 8: go up installation one support (32) at connecting plate (20), depression bar (31) is connected on the support (32) by a rotating shaft (not drawing among the figure).The staff can will have an end of arrow to depress along the direction of arrow above the depression bar (31), by pulley (30) and cover plate (26), arm pin (29) is moved downward along the direction of arrow, until cover plate (26) be pressed in simultaneously connecting plate (20) above [annotate: between figure cover plate (26) and the connecting plate (20) fixed gap is arranged].Last staff injects an end of depression bar (31) in the retainer ring (33) again.Since support (32) and retainer ring (33) all be mounted in connecting plate (20) above, so adopt depression bar (31), by pulley (30), cover plate (26) and arm pin (29), arm (22) promptly is fixed on the connecting plate (20).With arm (22) from connecting plate (20) when pulling up, can be at first an end of depression bar (31) be taken out and upwards lifts in retainer ring (33), (can referring to Fig. 6) then releases cover plate (26) below pulley (30), the staff hands arm (22) and upwards exerts oneself, and arm (22) is promptly broken away from connecting plate (20) to rising together with arm pin (29).
The mechanism for assembling-disassembling of arm among Fig. 1 (22) is also more simpler than shown in Figure 6, the driven pulley among Fig. 6 (24), driving wheel (25), power transmission shaft (10), plug (28) and socket (27) is removed get final product.The operation principle of remainder identical (as shown in Figure 8).
In all transmission lines, by circuit form by a lead, by circuit form by two or four leads.Because guide roller is to be crimped on the lead, therefore, should be equipped with the quantity of guide roller according to the radical of horizontal lead on every circuit.For example: by circuit form by two leads, but two leads are to be arranged above and below, and a guide roller then is installed on arm is got final product; By circuit form by 4 leads, these 4 arrangements of conductors become a square, horizontal lead radical is 2, then level is installed two guide rollers and is got final product on every arm.
When above-mentioned dolly drove to specific position such as circuit turning, because the lead of this position is to be flexible coupling, so the staff can unload dolly down from circuit, walk around be flexible coupling after, dolly is hanging to continues on the circuit to travel again.
Except that parts such as engine, clutch must adopt the metal material making, other parts all should adopt insulating material to make among the above embodiment.
Also can install wheel, make above-mentioned dolly have the function of on highway, travelling, use to make things convenient for the staff in the bottom of above-mentioned dolly driving cabin.
