Description
Technical field
The present invention relates to transmission line rope ladder servicing unit field, more particularly to a kind of 110kV transmission line rope ladders locking
Hook.
Background technology
At present, the rope ladder for being used on 110kV transmission lines of electricity is linked up with three parts by terraced head, terraced body and terraced tail mostly and is constituted.
Terraced tail hook is simple irony hook, and without blocking device, rope ladder hangs that to complete aft hook easy to fall off.Such as hanging when rope ladder head
Position is improper, and hook comes off, and rope ladder will float towards the direction away from operating personnel so that the operating personnel of lower wire can't reach soft
Ladder, causes to climb inconvenience.And the abrasion of wire can also be caused due to rubbing action in the contact position of hook and wire.
The content of the invention
It is an object of the invention to provide 110kV transmission line rope ladders locking hook, can effectively solve the problem that the terraced tail of rope ladder
Hold caducous problem.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions：110kV transmission line rope ladders
Locking is linked up with, including rope ladder fixing device, connecting rod, spring, locking pressing plate, lock, gripper shoe and arc buckle, the rope ladder
Connecting rod is housed in fixing device, gripper shoe in connecting rod, is fixed with, gripper shoe lower end is provided with arc buckle, and arc buckle is provided with
Opening upward, connecting rod lower end are connected with locking pressing plate by spring, and locking pressing plate is slidably connected with gripper shoe, locking pressing plate
It is provided with the lock for closed opening.
Preferably, the rope ladder fixing device includes base, installation axle and clamping nut, and installation is vertically provided with base
Axle, the clamping nut equipped with connecting rod, rope ladder connect band and a fixation in installation axle.By clamping nut connecting rod and
Rope ladder connect band is fixed on base, easy accessibility, simple structure.
Preferably, cushion pad is provided between connecting rod and rope ladder connect band.Cushion pad prevents connecting rod and rope ladder connect band
Phase mutual friction is damaged.
Preferably, gripper shoe is provided with dovetail groove towards the side of connecting rod, and dovetail groove is arranged along gripper shoe length direction,
To remain silent, dovetail groove is fixedly connected with locking pressing plate built with T-shaped slide block, T-shaped slide block at dovetail groove two ends.Dovetail groove and T-shaped are slided
The design of block, that is, can guarantee that locking pressing plate can be slided up and down, and be avoided that locking pressing plate departs from gripper shoe again.
Preferably, when T-shaped slide block is in dovetail groove the top, lock is closed with arc buckle.When in use, work as lock
Not by the case of external force effect, spring can move dovetail groove to topmost lock, lock and arc buckle is smoothly closed
Close.
Preferably, spring washer is provided with the inside of arc buckle.Reusing arc buckle folder wire makes, and spring washer can prevent wire from grinding
Damage.
Preferably, arc buckle is provided with guiding bar.Guiding bar is used to guide wire to snap in arc buckle.
Compared with prior art, it is an advantage of the invention that：Locking pressing plate is provided with lock, and gripper shoe is slided with locking pressing plate
Connection, changes lock position and then opens or close arc buckle by being slidably connected, easy to operate；Connecting rod lower end passes through bullet
Spring is fixed with locking pressing plate, carries out reset self-locking, simple structure to the lock opened by the elastic force of spring.
Description of the drawings
Structural representation when Fig. 1 is present invention lock and arc buckle closure；
Structural representation when Fig. 2 is present invention lock and arc buckle opening；
Fig. 3 is the cooperation schematic diagram of gripper shoe and locking pressing plate.
Specific embodiment
Below in conjunction with the accompanying drawings embodiments of the invention are further illustrated：
As shown in Figure 1 and Figure 2,110kV transmission line rope ladders locking hook, including rope ladder fixing device, connecting rod 2, spring
4th, locking pressing plate 5, lock 51, gripper shoe 6 and arc buckle 62.Rope ladder fixing device includes base 1, installation axle 12 and clamping spiral shell
Female 13, installation axle is vertically provided with base, the clamping spiral shell equipped with connecting rod, rope ladder connect band and a fixation in installation axle
It is female.Cushion pad 11 is provided between connecting rod and rope ladder connect band, the cushion pad is made up of silica gel.Connecting rod lower end passes through spring
Be connected with locking pressing plate, locking pressing plate is provided with lock, in connecting rod, welding or bolt connection have a gripper shoe 6, gripper shoe with close
Lock pressing plate is slidably connected, and gripper shoe lower end is provided with arc buckle 62, and arc buckle is matched with lock.It is provided with the inside of arc buckle
Spring washer 64 prevents wire from wearing and tearing.Arc buckle is provided with guiding bar 63, and guiding bar is used to guide wire to snap in arc buckle.
As shown in figure 3, gripper shoe is provided with dovetail groove 61 towards the side of connecting rod, dovetail groove is along gripper shoe length direction
Arrange, to remain silent, dovetail groove is fixedly connected with locking pressing plate built with T-shaped slide block 7, T-shaped slide block at dovetail groove two ends.When T-shaped is slided
When block is in dovetail groove the top, lock is closed with arc buckle；When T-shaped slide block is in dovetail groove bottom, latch and arc
Shape buckle is separated, and can be put into wire in arc buckle.During in order to ensure that locking pressing plate is not acted on by external force, dovetail can be in
Groove topmost makes lock close with arc buckle, and spring must all the time in the state that is stretched.
When unused, the state of the present invention is as shown in Figure 1.During use, lock is first stirred to dovetail groove bottom, make lock
Separate for arc buckle, wire is snapped in arc buckle.Unclamp lock again, the elastic force of spring makes lock return to dovetail groove most to go up
End, makes the closure of lock and arc buckle.Finally rope ladder connect band is bundled on rope ladder and completes to install.
The present invention has auto-lock function, improves the stability that rope ladder hangs, and security performance is greatly improved；Hook and wire
Contact position abrasion is reduced, and reduces the loss to Work tool and construction material；Install when rope ladder equipped with the present invention is used, remove
It is very simple and convenient, save the amount of labour.
The specific embodiment of the present invention is the foregoing is only, but the technical characteristic of the present invention is not limited thereto, Ren Heben
