Description
Technical field:
The utility model relates to a kind of machine rail clamping device.
Background technology:
Rail clamping device is to prevent that rail mounted from moving the free-moving safety device of mechanical direction along ng a path, and it is applicable to the wind resistance of rail mounted lifting haulage equipments such as various bridge-types, transfer crane and resists other external shock power.When Host Shutdown was stopped using, rail clamping device clamped rail automatically, holds main frame, to guarantee that main frame is not blown off by wind.When main frame starts use, then leg lock is opened, to guarantee main frame walking freely in orbit with electric hydaulic or with manual mode.
Existing rail clamping device mainly is made up of electric motor drive unit, mechanical clamp connecting rod mechanism and auxiliary mechanism's three parts.Wherein, the mechanical clamp connecting rod mechanism mainly comprises the parts such as guide piece of clamp, connecting rod, control caliper unit, and auxiliary mechanism mainly is made up of inhibiting device, guide piece, lubricating system etc.Because rail clamping device is used for work such as the lifting, transhipment of dam crest equipment, belongs to the open work environment.Owing to be installed in outdoor exposing to the sun and rain, corrosion is serious, adds that operation hours is long, is not easy to maintenance again, and the rail clamping device operation is unreliable, often is can't open after clamping, at last have to be out of service.Adopting in addition utilizes electrical motor to drive the rail clamping device of two clamp grip track by lead screw transmission, because complex structure, the rail clamping device jaw can not carry out the position automatic compensation again, cause in operational process, often occurring the situation of the monolateral clamping of clamp, and after each rail clamping device fault generation, can only take the interim method of manually removing to guarantee that equipment can continue to use at the scene, lost its capability of anti-wind in normal operation and rail clamping device will lose its grip track when inactive function and effect, at this moment can only treat after the end of job again to rail clamping device place under repair, adjustment.And each repair, adjust and all can not thoroughly solve this type of problem and promptly control table and do not effect a permanent cure, cause the rail clamping device double faults constantly to take place, both spent great amount of manpower and material resources, production has been caused to have a strong impact on again, simultaneously device security has been produced hidden danger.So this problem must effectively be solved.So that the safe and stable operation of door machine.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art and the tight Minato of a kind of structure, low cost of manufacture are provided, can reduce the maintenance number of times, reduces labor intensity, and the door machine rail clamping device of safe and reliable guarantee is provided for the maintenance of unit and gate.
For achieving the above object, the technical scheme of employing is:
A kind of machine rail clamping device, comprise support and the left and right sides clamping plate that can be installed in the track both sides on a machine that is installed in and the track correspondence position, the lower end of described support is equipped with horizontally disposed bearing pin, described left and right sides clamping plate are installed on the described bearing pin, described left and right sides clamping plate are provided with work station and inoperative station around described bearing pin rotation, described left clamping plate are connected by screw flight with described right clamping plate and rotate described screw rod to make and described left clamping plate and described right clamping plate counter motion the anchor fitting that can fix described left and right sides clamping plate when described left and right sides clamping plate are in the inoperative station is installed also on the described support.
Described anchor fitting comprises the adapter plate that is arranged on described bearing pin top, clamping plate both sides, the described left and right sides, described adapter plate is provided with " 7 " shape chute, be provided with a pin rod in the chute of described two adapter plates, described pin rod can be movable in described chute, when described left and right sides clamping plate are in the inoperative station, described left and right sides clamping plate are installed between described two adapter plates, and mobile pin rod, make described left and right sides clamping plate be fixed between described support and the described pin rod.
Described rotary blade is by being bolted on the described rotary tillage tool rest.
Owing to adopt said structure, the utlity model has following advantage:
1) this device adopts simple physical construction, utilizes screw rod to control left and right sides clamping plate grip track, and the existing clamping action of track is had the effect of jail, top again, and top power and gripping power increase automatically with the increase of hoisting crane motion external force.Locking effect is remarkable, guarantees that equipment is not blown away by strong wind.
2) utilize bearing pin, make left and right sides clamping plate when not working, can be received on the support, so the tight Minato of structure, safety, reliable, low cost of manufacture, owing to not taking too much space, applied widely simultaneously, both can be used for also can be used on the heavy duty crane on the middle-size and small-size hoisting crane.
In sum, the tight Minato of this apparatus structure, low cost of manufacture, can reduce the maintenance number of times, reduce labor intensity, for the maintenance of unit and gate provides safe and reliable guarantee.
Description of drawings:
Fig. 1 is a lateral plan of the present utility model;
Fig. 2 is a front view of the present utility model;
The specific embodiment:
Below in conjunction with accompanying drawing, further describe the specific embodiment of this patent.
As shown in Figure 1, 2.This device comprises support 1 and is located at left clamping plate 3 and right clamping plate 4 on the support 1, the below of support 1 is provided with horizontally disposed screw rod 5, left side clamping plate 4 and right clamping plate 3 are symmetrically set on the screw rod 5, screw rod 5 is provided with two screw threads, when making screw rod 5 rotations, left side clamping plate 4 and right clamping plate 3 move in the opposite direction, the upper end of left side clamping plate 4 and right clamping plate 3 is installed on the bearing pin 2, bearing pin 2 is installed between two parallel bars 8 of support 1, two parallel bars, 8 tops are equipped with the adapter plate 11 that is fixed on the support 1, and described adapter plate 11 is provided with " 7 " shape chute 9, and pin rod 6 is arranged between two chutes, and limit its horizontal direction by nut and move, a side of bearing pin 2 is provided with locking plate 7.
Elder generation's rotary screw 5 makes left clamping plate 4 and right clamping plate 3 break away from track 10 during operation, manually lift left clamping plate 4 and right clamping plate 3 lower ends, allow it be close to support, mobile pin rod 6 in chute 9 then, make left clamping plate 4 and right clamping plate 3 be fixed between support 1 and the pin rod 6, can make the hoisting crane normal operation like this;
