Description
Technical field
The utility model relates to a kind of suspender that is contained on the loop wheel machine, more specifically relates to a kind of mechanical type formula automatic rail gripping apparatus, is particularly useful for the lifting certainly of railway track.
Background technology
Long rail product is that the long Rail Production process flow of China has at rail welding plant (or weldering base of the rail ground) processing and fabricating: the welding rail hangs and unloads, stores classifiedly and join rail, weldering rail.The employed hanging device of each Railway Bureau's rail welding plant of China still is cooresponding simple and easy at present, only be whenever to be separated by 16 meters an electric block is set, as lift 500 meters long rails with regard to 32 electric blocks of needs configuration, operating personal of each cucurbit configuration during lifting, hand-held button lifts by the mutual coordination with adjacent personnel, lift hook and still rely on manually, the operating efficiency that 500 meters long rail after particularly welding are loaded onto long rail car is extremely low.Workman's hook, unhook are frequently.Hurry back and forth back and forth, labour intensity is big.
Automatically grabbing the suspender that rail is put rail for realizing, must be the reversible physical construction of sequence of operation from the principle, and the rail of grabbing that motion drives is put rail and guaranteed from mechanical self-locking structure.For addressing this problem, the employing compressed air that has realize that grabbing rail automatically puts rail, but investment is big, uses inconvenient.The difficulty of later period maintenance maintenance simultaneously.The employing electromagnet that has is grabbed rail automatically by energising, the realization that has a power failure and is put rail, and secure context has a misgiving.The employing four-bar linkage that has leans on the rail deadweight to grab rail after deadweight is broken off relations, sling by suspender, but this mode suspender is from weighing 800kg, inconvenient operation, cost height
At present, use pressurized air or electromagnet etc. to need the rail of grabbing of propulsion source to put the rail suspender, all be subjected to very big environmental constraints, in abominable operating environment, safety is had a greatly reduced quality, and complex structure, volume weight is big, and corollary equipment is many, operation inconvenience, no matter be to make or later maintenance early stage, all with high costs.
Therefore, need innovate prior art, design and a kind ofly need not drive power source, not limited by operating environment, simple and lightly reliably, safe, easy to operate be easy to safeguard, only can grab the suspender that rail is put rail automatically by mechanical movement, and this suspender is easy to make and is with low cost, is convenient to widespread use.
Summary of the invention
The purpose of this utility model is to be to provide a kind of mechanical type automatic rail gripping apparatus, it need not drive power source, not limited by operating environment, only can grab rail automatically and put rail by mechanical movement, simple in structure, easy to operate, practical reliable, with low cost, reduced working strength of workers, improved work efficiency.
To achieve these goals, the utility model adopts following technical measures:
Automatic rail gripping apparatus described in the utility model, by the hook seat, flap seat, guide plate, jig arm, connecting rod is formed, and the hook seat is made up of shackle plate, upper ring gear, lower ring gear, screw rod, T type hook, and primary shaft, second are arranged on the flap seat.
Jig arm is connected with flap seat by the primary shaft on the flap seat, second, jig arm is used to catch and the clamping rail, connecting rod one end is connected with the hook seat by axle, and the other end is connected with jig arm by axle, and connecting rod and jig arm are connected to form four-bar linkage structure, up-and-down movement by the hook seat, drive four connecting rod displacements, jig arm is only needed by the moving up and down of hook seat, and need not other operations, be deployable or close and to close, realize the action of grabbing, putting rail.
The upper ring gear of being adorned in the hook seat, lower ring gear, screw rod and T type hook are on the same axis, upper ring gear is fixed in the hook seat, T type hook one end is connected with lower ring gear by screw rod, the T type hook other end is connected with flap seat, during hook seat up-and-down movement, T type hook can be along the axis up-and-down movement in flap seat, flap seat is sling or is put down, lower ring gear can rotate along with T type hook up-and-down movement, by lower ring gear rotate with upper ring gear separate, mesh realization mechanical self-latching and release.
Guide plate is fixed on the flap seat, is used for guiding when off the hook rail to slip into the desired location, and shackle plate is used for being connected with loop wheel machine.
The utility model principle of work is as follows: this device is by on shackle plate connection and the loop wheel machine, after moving to directly over the rail that needs lifting, to bottom offset, after guide plate guiding rail on the flap seat slips into the desired location, loop wheel machine hauling hook seat moves up, and jig arm is caught and the clamping rail with moving on the hook seat and close and close, T type hook is with moving until the flap seat of slinging on the hook seat, thereby rail caught sling, owing to adopt four-bar linkage structure, the downward gravity that the rail deadweight produces, can drive four connecting rods and make the tight clamping of jig arm, move past in the journey on the hook seat, upper ring gear separates with lower ring gear, and lower ring gear on T type hook, move past rotate in the journey with upper ring gear can not position engaged, form self-locking, like this, when jig arm catch and the clamping rail after, in the process that loop wheel machine is hung oneself, no matter because of vibrations or other reasons, jig arm all can not be launched rail is come off.After putting down rail, T type hook moves down, lower ring gear rotate to can with the upper ring gear position engaged, remove self-locking, make T type hook can continue to move down, thereby make jig arm can launch the relieving rail.
The utility model compared with prior art has the following advantages and effect:
The utility model grab rail put rail need not propulsion source, only can realize by mechanical movement, use not limited by operating environment, also can dependable service under the harsh environment even wait in the open air.
The utility model guarantees safety in the mode of mechanical self-latching, and is safe.In the actual application, as long as after suspender was caught the rail lifting, under the effect of rail gravity, no matter run into which kind of situation, suspender all can not be opened the lifting safety that suspension hook is guaranteed rail with self-locking.
The utility model structure is simple lightly reliably, easy to operate to be easy to safeguard, load onto any loop wheel machine can use, and Applicable scope is extensive, and the steel plant that are specially adapted to railway weldering rail factory and produce rail use.
In addition,, therefore be easy to manufacturing and with low cost, higher economical efficiency and practicality are arranged because the utility model is the mechanical type design.
