Specific embodiment
To describe technology contents, structural feature, institute's reached purpose and effect of the present invention in detail, embodiment is hereby enumerated below
And coordinate accompanying drawing to be explained in detail.
Refer to shown in Fig. 1, and combine shown in Fig. 2 to Fig. 4, the present invention provides a kind of contact net car ladder track-catching device, its bag
The catching 20 that a pedestal 10, radial type is installed on the pedestal 10 is included, wherein, pedestal of the invention 10 includes two parallel intervals
The side plate of setting and the top board being installed between two sides, catching 20 be installed between biside plate and can around with side plate hinged place
Rotate, movable on top board of the invention that a pull bar 30 is housed, the bottom of pull bar 30 is provided with one and can act on pushing away in catching 20
Plate 31, and the top of pull bar 30 is equiped with a cam 32, cam 32 can be rotated relative to pull bar 30, and in cam 32 and the pedestal 10
Between pull bar 30 on be set with a drive sleeve 33, make the one end of drive sleeve 33 can batch (-type) be in contact with cam 32, its other end
Contradict on the top board of pedestal 10, a spring housing 34, spring housing 34 are provided with inner face of the drive sleeve 33 near the side of push pedal 31
It is sleeved on pull bar 30, during action, cam 32 can be promoted to relatively rotate, i.e., using the not isometrical rotation of cam 32 so that spring
Set about 34 shrinks, so as to drive the pull bar 30 to carry out stretching motion, and then causes that the push pedal 31 of the bottom of pull bar 30 applies active force
In catching 20, it is opened or is closed, and due to the effect of spring housing 34, can effectively ensure that the position of cam 32 is stablized relatively
(cam 32 will not be caused to rotate automatically because of extraneous shake somewhat etc.), the stability that influence catching 20 is clamped；The side of pedestal 10
A support 40 is also equipped with plate, and an anchor ear 41 for being locked is equiped with the end of the support 40.
When using, with rail can be combined together contact net car of the invention ladder track-catching device by catching 20 by user, and
By the anchor ear 41 on support 40, linked together contact net car is terraced with contact net car of the invention ladder track-catching device, so that can
Be stably fixed to contact net car ladder on rail by realization, and car ladder is toppled over, slided down when can completely avoid operation, is constructor
Member, equipment have safely provided guarantee, while reduce person works' intensity and save manpower；When need change contact net car
During terraced position, it is thus only necessary to which promoting cam 32 to rotate release catching 20 just can realize that contact net car ladder is separated with rail, use
It is more convenient.
In order to further describe technical scheme, please continue to refer to shown in Fig. 1, this is convex using new
A push rod 35 is equiped with wheel 32, it is more time saving and energy saving when promoting cam 32 to rotate to further facilitate.Preferably, the present invention
Pedestal 10 on be equiped with two catchings 20, two radial types of catching 20 are installed on the pedestal 10, with by two catchings 20
Further strengthen the locking active force between catching 20 and rail, and because catching 20 is hinged with push pedal 31, so that
When cam 32 drives pull bar 30 to move, push pedal 31 is capable of achieving simultaneously to two active forces of catching 20, it is preferred of the invention
Catching 20 is high-strength insulation catching 20.
Please continue to refer to support plate 42 and connection two that shown in Fig. 4, support of the invention 40 is set including two parallel intervals
The connecting plate 43 of individual support plate 42, support 40 is separately fixed at two lateral surfaces of side plate by two support plates 42；And in push pedal 31
Two through holes are provided with, the catching is provided with a waist-shaped hole, and push pedal 31 can by installing a bolt in the through hole and waist-shaped hole
Rotary type is connected in push pedal 31, so that when cam 32 carries out not isometrical motion, can drive catching 20 by push rod 31
Rotated relative to the interface point with pedestal 10, realize that it opens or closing motion.
Compared with prior art, its advantage is the present invention：A kind of contact net car ladder track-catching device of the invention, by setting
The catching 20 in the bottom of pedestal 10 is put, and is rotated using cam 32, drive pull bar 30 to move upwards, by the push pedal of the end of pull bar 30
31 are pulled upwardly, and push pedal 31 drives claw 20 to be rotated around the bolt being hinged with pedestal 10, it is clamped on rail, and using dress
The anchor ear 41 on support is located at, by anchor ear 41 and the steel pipe locking of contact net car ladder bottom, so as to realize contact net car ladder and rail
Be connected, it is ensured that the stability of contact net car ladder, and when not in use, can by unclamp catching 20 realize contact net car ladder with
The separation of rail, it is more convenient using dismantling.It is of the invention compared with traditional contact net car ladder, it is fixed using equipment
Car ladder replaces artificial fixed car ladder, it is entirely avoided car ladder is toppled over, slided down during operation, is that workmen, equipment are safely provided
Ensure, while reduce person works' intensity and save manpower；And not isometrical motion and the lever of ingenious utilization cam 32
Principle, easily control insulation catching 20 is moved；And the relatively simple structure of catching 20, low cost of manufacture, the weight of insulating of the invention
Amount is light, is easy to carry, and installing/dismounting and operation are simple and easy to apply.
In sum, only the preferred embodiments of the invention, does not limit protection scope of the present invention with this, all according to the present invention
Equivalence changes that the scope of the claims and description are made and modification, are all within the scope of patent of the present invention covers.
