Abstract
The automatic protection device is suitable for the tippler heavy shunting machine. If the length of the train carriage entering the transfer platform is too long, the overlong train carriage can crash accessory equipment of the transfer platform after the heavy shunting machine pushes an empty train to the transfer platform, and the heavy shunting machine does not have electric protection in the aspect, so that the risk of equipment damage exists. The utility model comprises the following components: the distance measurement type car dumper is characterized by comprising two groups of distance measurement type induction switches (5) fixed on a tail support (7) of a car pulling platform and a relay fixed in a car dumper control cabinet, normally closed contacts (2) of the two groups of distance measurement type induction switches are connected in series with a relay coil (4), and normally open contacts of the relay are connected in series in a car pulling permission circuit (8). The utility model is suitable for automatic protection of the tippler heavy shunting machine.
Description
Technical Field
The utility model relates to an automatic protection device suitable for a tippler heavy shunting machine.
Background
The C-shaped rotor type tippler is mainly used for dumping train coal in a thermal power plant. The train coal carriage is drawn to the tipper body through the heavy regulating machine, and is turned over for 180 degrees along with the C-shaped rotor of the body after being pressed by the tipper, coal in the carriage is turned over to the coal grate layer, and falls into equipment such as a coal feeder below after large blocks are screened by the coal grate layer, so that the train coal is turned over and unloaded. And pushing the unloaded empty vehicle to a transfer platform through a readjusting machine.
The existing C-shaped rotor type car dumper also has the following problems to be optimized:
because the types of the train carriages in the railway departments are different and the lengths of the train carriages are different, if the length of the train carriage entering the transfer platform is too long, the overlong train carriage after the re-dispatching machine pushes an empty train to the transfer platform can crash accessory equipment of the transfer platform, and the re-dispatching machine has no electric protection in the aspect, so that the risk of equipment damage exists.
Disclosure of Invention
The utility model aims to provide an automatic protection device suitable for a tippler reset machine.
The above purpose is realized by the following technical scheme:
the automatic protection device comprises two groups of distance measurement type induction switches fixed on a tail support of a car pulling platform and a relay fixed in a car pulling machine control cabinet, wherein normally closed contacts of the two groups of distance measurement type induction switches are connected in series and then connected in series with a relay coil, and normally open contacts of the relay are connected in series in a circuit allowing car pulling.
The automatic protection device suitable for the tipper retuning machine is characterized in that the allowable car pulling circuit comprises a forward switch and a retuning machine car puller, and the forward switch is connected with the retuning machine car puller in series.
Has the advantages that:
1. according to the utility model, whether the length of the carriage in the transfer platform exceeds the body area of the transfer platform can be effectively judged through the two groups of distance measurement type inductive switches, when the length of the carriage exceeds the body area of the transfer platform, the distance between the distance measurement type inductive switches and the carriage is reduced to reach a set value, at the moment, the normally closed contacts of the distance measurement type inductive switches are disconnected, the relays are powered off, the normally open contacts of the relays are disconnected, the carriage cannot be drawn, the carriage does not collide with transfer platform equipment in the empty vehicle entering process, the transfer logic protection can be effectively carried out, and the safety of personnel and equipment is ensured. The safety performance of the tipper system is greatly improved. And the structure is simple, the manufacturing cost is low, the safety and the reliability are realized, and the operation is convenient.
Description of the drawings:
FIG. 1 is a circuit diagram of the present invention;
FIG. 2 is a schematic diagram of the present invention after installation;
in the figure: 1. a forward switch; 2. normally closed contacts of the distance measurement type inductive switch; 3. readjusting the tractor-trailer; 4. a relay coil; 5. a distance measurement type inductive switch; 6. a railway car; 7. a support; 8. allowing for a tow circuit.
The specific implementation mode is as follows:
example 1:
the utility model provides an automatic protection device suitable for tipper is reset, its constitution is including two sets of range finding formula inductive switch 5 on the support 7 that is fixed in ground and the relay in being fixed in the tipper switch board, two sets of range finding formula inductive switch's 2 series connection back with relay coil 4 establish ties, the normally open contact of relay establish ties in allowing the circuit 8 that leads.
Example 2:
the automatic protection device suitable for the returner of the tippler according to embodiment 1, the car pulling permission circuit comprises a forward switch 1 and a returner tractor 3, and the forward switch is connected with the returner tractor in series.
The working principle is as follows: two sets of distance measuring type inductive switches are arranged at the tail of the transfer platform, a relay KA1 is additionally arranged on the program control cabinet of the tippler, when the tippler operates normally, normally closed contacts of the two sets of inductive switches control the relay KA1 to be electrified, and normally open contacts of the relay KA1 are closed, so that the returner is allowed to start the tractor to pull an empty car into the transfer platform. When the carriage length is too long, the distance between the distance measurement type induction switch and the carriage is reduced, when the distance reaches a certain distance, any induction switch acts, the normally closed contact is disconnected, the relay loses power, the normally open contact of the relay is disconnected, and the readjusting machine is not allowed to continue to pull the vehicle to the transfer platform, so that the safety of equipment and personnel is ensured.
Claims (2)
