Abstract

Train locator of coal tipping apparatus relates to an assistant device of coal tipping apparatus, in particular a train locator belonging to the coal tipping apparatus system. The locator comprises a pin column 1 fixed on a base on external side of a track 5 via a bracket 2 and a wedge shaped support arm 3 connected fixedly with the bracket. The wedge shaped support arm 3 is connected with a spring 6. A shear lug 4 is arranged in front of the wedge shaped support arm 3. When the train steers, the wheel pushes the support arm outwards, which does not affect normal steering of the vehicle. After the wheel moves, the support arm, under effect of the spring 6, rotates to a position clinging to the track and the shear lug adheres on the track surface, which prevents the wheel from being moving backwards to avoid retrograde motion of the vehicle. The utility model completely uses mechanical transmission manner and has simple and reliable structure, lower manufacturing and maintenance cost and small work load of maintenance, which to a large extent, ensures high efficiency of the coal tipping apparatus system.

Description

Coal tipper train positioning device

Technical field

The utility model relates to a kind of auxiliary device of coal car dumper system, particularly belongs to a kind of train positioning device of coal car dumper system.

Background technology

The coal tipper is that coal commonly used such as port and pier, power plant unloads vehicle device.Existing car dumper system is the increasingly automated high efficiency vehicle device that unloads, and mainly is made of equipment such as clip wheel device, positioning car, car puller, tippers.The radical function of clip wheel device is: make train be stabilized in assigned position fast, prevent that the phenomenon that inertia and bounce make train break away from assigned position from taking place, and realizes the purpose that high efficiency is unloaded.But; present clip wheel device adopts hydraulic transmission mode; the hydraulic efficiency pressure system complicated by a cover realizes technical support, its complex structure, and fault is various; the frequent replacing of parts causes the great amount of cost expenditure; the maintenance maintenance work capacity is big, has not only increased maintainer's labour intensity, and the frequent shutdown that causes thus; have a strong impact on the working out of production scene, restricting the normal performance of coal tipper modernization process level to a great extent.

Summary of the invention

The purpose of this utility model promptly is to provide a kind of later-model coal tipper train positioning device, with the purpose that reaches simple in structure, fault rate is low, safe and reliable.

Coal tipper train positioning device disclosed in the utility model is set in fixing pin on the pedestal of the track outside by the cylindrical shape bearing, and both can relatively rotate.Be the hold-down arm of wedge shape with having of bearing fixed connection, connect spring on the hold-down arm, the fixed end of spring is fixed on the pedestal.The front end of hold-down arm is a stop block, and obviously, the bottom surface of stop block should be a little more than the end face of track.

Coal tipper train positioning device disclosed in the utility model, to overtake the time, wheel is pushed hold-down arm to the outside at train, can not hinder the cruising of vehicle.After wheel crossed, hold-down arm forwarded the position of the track that reclines under the effect of spring, and stop block is attached on the orbital plane, can stop wheel to rotate backward, thereby played the effect that prevents that vehicle from driving in the wrong direction.Because the utility model adopts mechanical drive mode fully, simple in structure, do not need power in the work, safe and reliable, so have the advantages that to make with maintenance cost is low, the maintenance maintenance work capacity is little, after replacing existing hydraulic pressure clip wheel device, can promote the reliability of existing overturning technology greatly, ensure the high efficiency performance of car dumper system to the full extent.

Description of drawings

Accompanying drawing discloses specific embodiment of the utility model, wherein:

Fig. 1, the utility model structural representation front elevation;

Fig. 2, the utility model structural representation left side view;

Fig. 3, the utility model structural representation birds-eye view.

The specific embodiment

As shown in drawings, coal tipper train positioning device disclosed in the utility model comprises the square stop block 4 of a columnar bearing 2, the hold-down arm 3 that is wedge shape and hold-down arm 3 front ends.Cylindrical shape bearing 2 cooperates with pin 1, and both can relatively rotate.Pin 1 is fixedly mounted on the pedestal in track 5 outsides.As shown in Figure 1 and Figure 2, the bottom of hold-down arm 3 and bearing 2 fixed connections, the other end then are stop block 4.Obviously, the bottom surface of stop block 4 should be a little more than the end face of track 5.

As shown in Figure 3, hold-down arm 3 rear ends connect a coil spring 6, and the fixed end of spring 6 is fixed on the pedestal.Based on the effect of spring 6, hold-down arm 3 of the present utility model and stop block 4 recline in orbit under normal conditions, when train through out-of-date, wheel to overtake take advantage of a situation with hold-down arm 3 push to the outside, can pass through smoothly.After wheel crossed, hold-down arm 3 was got back to the position of the track that reclines under the effect of spring 6, and stop block 4 is attached on the orbital plane, thereby played the effect that stops wheel to travel backward.

Coal tipper train positioning device disclosed in the utility model, effectively replace complex, expensive existing clip wheel device equipment, can play the effect that makes train fast and stable, anti-anti-retrograde equally, installations and facilities have not only been simplified, reduced fault rate, improve production efficiency, and reduced equipment input and artificial maintenance load, thereby reduced labour intensity and productive costs.In addition, can also reach energy-saving and cost-reducing purpose, can save every year such as a large amount of hydraulic oil, machine parts, power consumption etc., has high economic benefit.

Claims

1, a kind of coal tipper train positioning device, be set in fixing pin (1) on the pedestal of track (5) outside by cylindrical shape bearing (2), it is characterized in that, with bearing (2) fixed connection wedge shape hold-down arm (3) arranged, hold-down arm (3) is gone up and is connected spring (6), and the fixed end of spring (6) is fixed on the pedestal; The front end of hold-down arm (3) is stop block (4).
