Specific implementation mode
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 1 to Figure 27, the high mast lighting jacking system of speed limit fall arrest of the invention, by steel wire rope rope distributor 1,
Speed limit anti-falling mechanism, steel wire rope guiding mechanism 4, main rope hoist engine 13, safety steel cable automatic deploying and retracting rope hoist engine 6 etc.
Composition.
As shown in Fig. 5 to Fig. 8, steel wire rope rope distributor 1 be double lifting point steel wire rope rope distributor, double lifting point steel wire rope rope distributor by
Upper and lower two layers of platform sling composition, it is each there are one suspension centre below every layer of platform sling, this two suspension centres respectively with main steel that lifting drive is provided
Cord 2 is connected with the simple safety steel cable 3 for playing safeguard protection, after the suspension centre that main rope 2 is connected goes wrong,
The suspension centre being connected with safety steel cable 3 works instead of it.
As shown in Fig. 5 to 10, speed limit anti-falling mechanism is divided into external (see Figure 10) and built-in（See Fig. 5 to Fig. 9）.

Speed-limiting safety locks the existing mature technology of 5-- hanging basket industries, is centrifugal safety lock, has related rule in hanging basket industry
Model, according to<<Aerial work basket GB19155-2003>>Regulation:The lock rope speed of safety lock be less than 30 ms/min, lock rope away from
From less than 200mm, if main rope 2 or main winch 13 or other tie points go wrong if causing lamp panel to fall, peace
Full lock can immediately lock safety steel cable 3 when reaching lock rope element, the steel wire rope point that safety steel cable 3 passes through double lifting point
Rope device 1 and secondary steel wire rope A10, secondary steel wire rope B11, pair steel wire rope C12 are connected with lamp panel 9（Figure 11,12）, secondary steel wire rope A, B,
C10,11,12 heads are fixed with cover of wedge 14- and retainer clip 15, to prevent falling for lamp panel 9.Speed-limiting safety lock 5
Lock rope shortens braking distance, reduces the impact force of lamp panel for relatively with 3 meters of existing fall arrest less than 0.2M,
Risk greatly reduces；In addition existing fall arrest is mounted on lamp panel, so can thus increase lamp panel itself
Weight, and this speed-limiting safety lock is installed on the body of rod of bottom, does not increase weight to lamp panel, if carrying equally heavy lamp in this way
So as to mitigate the load of lamp panel, the load of head supporting structure 7 is also mitigated, improves safety coefficient, in other words safety coefficient
It can be with the certain lamps and lanterns of overloading if the same.
Steel wire rope guiding mechanism 4 is made of directive wheel and holder, it is therefore an objective to allow safety steel cable 3 that can enter limit as requested
Fast safety lock 5 and it is connected with safety steel cable automatic deploying and retracting rope hoist engine 6.
Such as Figure 13, shown in 14,15, safety steel cable automatic deploying and retracting rope hoist engine 6 only provides serving power when rising, and
And the torque more than setting under the action of clutch during rising will skid automatically, driven gear 49 can dally,
Prevent safety steel cable 3 from overloading.During the decline, automatic deploying and retracting rope hoist engine 6 does not provide power, lamp panel dead weight and
What clutch and hoisting speed reducer itself damping collective effect got off to realize hoist engine puts rope function；Hoist engine when not working,
As long as safety steel cable is slightly tensed, in the case where speed reducer damps, steel wire rope will not come loose.
As shown in figure 15, clutch is by hollow shaft 44, inboard friction piece 45, outboard friction piece 46, pressing plate A47, disc spring
A48, nut 50, bushing 59, flat key 60 form, and shaft rear end connects hollow shaft 44 by flat key 60, and hollow shaft 44 passes through bushing
59 connection driven gears 49, driven gear 49 and the driving gear engaged transmission being fixedly connected on the output shaft of driving motor connect
It connecing, 49 both sides of driven gear are respectively provided with medial and lateral friction plate 45, and 46, and outboard friction piece 46 passes through pressing plate A47, disc spring A48
With the axially contact connections of nut A5 being connected in hollow shaft 44.
Such as Figure 16, shown in 17, main rope hoist engine 13 includes belt pulley 53, and belt pulley 53 passes through hollow sleeve axis 51, lining
Set 59 and flat key 60 and driving axis connection, 53 both sides of belt pulley are respectively provided with friction plate A52, friction plate B54, and friction plate B54 is logical
It crosses pressing plate B55, disc spring B56 and forms friction clutch with 57 axially contact connection of nut on the driving shaft is connect, make king wire
When hoist engine 13 of restricting overloads, friction clutch skids, and belt pulley 53 dallies, no longer passing power, shields.
The problem of used is the clutch of steel-ball type, and this clutch is due to structure, it is easy to it wears, and the present invention
Clutch is friction plate, and service life greatly extends.
As shown in Figure 18 to Figure 27, indexing indicating mechanism is formed by linking up with indicating mechanism and unhook indicating mechanism, the two knot
Structure is similar.There are three cantilever, each cantilever insides to be fixed with several pieces of guide plates 58, several pieces of guide plates 58 for head supporting structure 7
It is formed by slot to be connected with hook axis 34, the guiding of hook and unhook for linking up with axis 34.
Link up with indicating mechanism：Including hook pointer 18, elastic pin shaft 33, bushing B42, instruction axis 41, split washer 32, axis
Bearing 43, hook push rod 22, hook instruction upper limit column 28, hook instruction lower limit column 29, hook limit bar 25.Indicate axis
41 both ends are connected to 7 lower part both sides of head supporting structure, and instruction axis is fixedly connected with hook push rod 22 and hook on 41 middle part
Bar 25 is limited, hook 41 one end of instruction axis is fixed on head supporting structure 7 corresponding equipped with hook pointer 18, hook index dial 20
The side of pointer 18 is linked up with, the hook instruction upper limit column 28 for limit is equipped in 7 side of head supporting structure, under hook instruction
Limited post 29, and instruction upper limit column 28, hook instruction lower limit column 29 are linked up with positioned at 25 both sides of hook limit bar；
Hook instruction operation principle:Under natural conditions, due to hook 22 gravity eccentricity of push rod and hook instruction lower limit column
29 the reason of, hook pointer 18 are directed toward O and see Figure 23, when hook axis 34 is moved upwards up to position A along guide plate 58, hook
Cap 23 starts to encounter hook push rod 22, and hook push rod 22 starts to rotate, and links up with pointer 18 at this time under the promotion of hook push rod 22
And then it rotates, is crossed when hook axis 34 and see Figure 24 above the C of the position in-positions B, link up with pointer 18 at this time and point to position P and see 23,
Position P illustrates that whether also this hook can check hook pointer 18 on other two cantilevers at this time with downlink in place
Through pointing to position P, it is to be ensured that all hook pointers 18 all point to or setover P, can control hook 34 downlink of axis；When
It so above also still can continue to rise later, when hook pointer 18 points to position Q, illustrate that lamp panel 9 has arrived at and most push up
Portion cannot rise and link up with push rod 22 namely link up with the slewing area of pointer 18 than shown in hook index dial 20 again
Range is big, can continue to rotate to until hook limit bar 25 meets hook instruction upper limit column 28 i.e. position M and see Figure 24,
When hook axis 34 moves down, hook push rod 22 also can be rotated down and then in the case where conducting oneself with dignity eccentric, be limited until linking up with
Position bar 25 encounter hook instruction lower limit column 29, at this time link up with pointer 18 be directed toward initial position O ', while link up with push rod 22 with
It links up with cap 23 to detach, when hook axis 34 crosses position C, connecting rod 27 returns to vertical state under the action of tension spring 26, hangs at this time
Hook axis 34 continues to move down, and the bottom until reaching 58 formed slot of guide pin is connected with guide pin 58, keeps connecting rod at this time
The main rope 2 of 27 bottoms slightly relaxes, and not be able to eat pulling force, and Figure 24 is shown in hook-hanging motion completion.
Unhook indicating mechanism：Including unhook pointer 17, unhook index dial 19, unhook push rod 21, break off relations instruction upper limit column
31, break off relations instruction lower limit column 30, dehooking limit bar 24, elastic pin shaft 33, bushing B42, instruction axis 41, split washer 32,
Bearing block 43.41 both ends of instruction axis are connected to 7 top both sides of head supporting structure, are fixedly connected on 41 middle part of instruction axis de-
It is fixed with dehooking limit bar 24 at hook push rod 21 and close instruction 41 step of axis, 41 one end of instruction axis is equipped with unhook pointer 17,
And unhook pointer 17 is located at same side with hook pointer 18, unhook index dial 19 is fixed on head supporting structure 7 corresponding unhook
The side of pointer 17, interior be equipped with of each cantilever in 7 side of head supporting structure refer to for the unhook instruction upper limit column 31 of limit, unhook
Show lower limit column 30, and the instruction upper limit column 31 that breaks off relations, the instruction lower limit column 30 that breaks off relations are located at 24 both sides of dehooking limit bar.
Break off relations instruction operation principle:Similarly, under natural conditions, due to 21 gravity eccentricity of unhook push rod and the instruction lower limit that breaks off relations
Position column 31 the reason of, unhook pointer 17 be directed toward O see Figure 23, at this time first control hook axis 34 rise, start hook axis 34 drawing
It is moved straight up under the action of spring 26, when encountering guide plate 58, when being moved upwards up to position E along it, hook cap 23 starts
Encounter unhook push rod 21, unhook push rod 21 starts and then to rotate, and unhook pointer 17 is followed under the rotation of unhook push rod 21 at this time
Rotation, when hook axis 34 crosses position F, hook axis 34 returns to vertical state under the action of tension spring 26, at this time unhook pointer 17
It points to position P and sees that 23, position P illustrate that this hook has been disengaged from the groove and can at this time have been checked on other two cantilevers with downlink in place
Whether unhook pointer 17 has also pointed to position P, it is to be ensured that all unhook pointers 17 all point to or setover P, can
Control hook 34 downlink of axis；Certainly it above also still can continue to rise later, when unhook pointer 17 points to position Q, say
Bright lamp disk 9 has arrived at top, cannot rise again, and the slewing area of unhook push rod 21 namely unhook pointer 17 than
Range shown in unhook index dial 19 is big, can continue to rotate to dehooking limit bar 24 and encounter unhook instruction upper limit column
See Figure 24 until 31 i.e. position M, when hook axis 34 moves down, unhook push rod 21 can also be followed in the case where conducting oneself with dignity eccentric
It rotates down, until dehooking limit bar 24 encounters unhook instruction lower limit column 30, unhook pointer 17 is directed toward initial position at this time
O ', while the push rod 21 that breaks off relations is detached with hook cap 23, finally when hook axis 34 leaves guide plate 58 completely, connecting rod 27 is in tension spring
Vertical state is returned under the action of 26, the action of unhook at this time is completed
The advantages of this architecture invention is whether in place can accurately to indicate hook 34, to determine when to carry out
The rising or step-down operation of lamp panel carry out hook and the unhook action of safe progress lamp panel；Avoid the occurrence of three hooks of lamp panel not
It can hang on three cantilevers of head supporting structure 7 or cannot while break off relations from three cantilevers of head supporting structure 7 simultaneously, from
And lead to security risk, because the case where cannot hanging up or take off simultaneously, bringing to routine use often occurs in existing hook
Inconvenient and security risk.
Such as Figure 22, shown in 25,26,27, extension spring-type hitch gear includes holder 35, spring support 36, axis pin B40, tension spring
26,27 baffle ring 39 of connecting rod, axis pin A37, bushing A38, hook cap 23, hook axis 34.Holder is rotated in 35 top by axis pin A37
Connecting rod 27 is connected, for 27 lower end of connecting rod by tension spring 26, axis pin B40 connecting springs holder 36,27 upper end of connecting rod is equipped with hook axis 34
And hook cap 23, the hook axis 34 and hook cap 23 connect head supporting structure 7 by indexing indicating mechanism.
Extension spring-type hitch gear operation principle：Under natural conditions, connecting rod 27 keeps vertical state under the action of tension spring 26,
When hook cap 23 encounters upper guide plate 58, connecting rod 27 can rotate, and after external force removes, connecting rod 27 can be in the work of tension spring 26
It is returned to original state under（Vertically）；And axis pin A37 uses copper using the bushing A38 between stainless steel and connecting rod 27
Material avoids getting rusty stuck.
Extension spring-type hitch gear advantage：This clever structure is novel, makes simple limitation not loaded, can be big according to load
It is small to change the structure size of associated part
