Abstract

The utility model discloses a coke guiding device, which belongs to a part of a coke guiding train and is used for guiding the red heat coke pushed from the coke oven to load into the train hopper of the coke picking train. A coke guiding groove (5) is fixedly connected to a coke guiding barrier (3) to form a rigid box-shaped structure. A hydraulic support device (6) is arranged on a coke guiding train body (8) arranged under the coke guiding groove, the lifting of the hydraulic support device (6) can be driven by a hydraulic cylinder (6a), and the hydraulic support device (6) supports the bottom of the coke guiding groove (5) in the out going of the coke. A hydraulic support device is used for replacing the rigid support device in the prior art by the utility model, so the clamping and blocking phenomenon caused by thermal expansion can be thoroughly eliminated. The utility model has the advantages of continuous normalrunning of the coke guiding train, high work efficiency of the coke guiding train, and little maintenance of the coke guiding train.

Description

A kind of coke guidance device

The utility model relates to a kind of coke guidance device, belongs to the part of coke guiding locomotive, is used to the red heat shape coke guiding of releasing from coke oven, it is packed into connect in the wagon box of burnt train.

Coke guidance device of the prior art shown in Fig. 4,5, mainly by upper rail 1, messenger 2, lead burnt grid 3, hydraulic drive mechanism 4, coke guide 5, bearing guiding device 6 and form, be installed on the car body 8 of coke guiding locomotive.Leading burnt grid 3 is the lower opening frameworks that are welded by H shaped steel grid frame and waved plate screen, hangs on upper rail 1 by the messenger 2 on its top.Coke guide 5 is between the opening of leading burnt grid 3, links by bearing pin 7 and the slotted hole of leading burnt grid 3 lower ends.Gap X between bearing pin 7 and the slotted hole can move up and down coke guide 5 with respect to leading burnt grid 3.Coke guide 5 is bearing on the bearing guiding device 6 that is made of guide rail and supporting rollern.Hydraulic drive mechanism 4 drives coke guidance device with respect to coke oven coke outlet 9 forward-reverses.Because the distance between upper rail 1 and the lower support liner 6 is a fixed, when leading burnt grid 3 expanded by heating, gap X makes and leads the space that burnt grid 3 have Free Transform.The existence of gap X make 2 of upper rail 1 and messengers bear the weight of leading burnt grid 3, and the weight of coke guide 5 and coke is born by guided bearing device 6 simultaneously.But gap X can not be infinitely great, in actual use owing to working accuracy with the reasons such as natural subsidence after using a section, gap X is reduced or do not exist fully.Discharging of the coke continuously like this, when leading burnt grid 3 expanded by heating, swell increment can't absorb, and coke guidance device will stuckly can't move between upper rail 1 and bearing guiding device 6.Could move after it must being cooled off one section, influence the coke oven ordinary production.Jam usually causes the damage of equipment simultaneously, has increased maintenance load.

The purpose of this utility model provides a kind of coke guidance device of not expanded by heating influence, to guarantee that coke guiding locomotive normally moves.

The purpose of this utility model realizes by following measure.With coke guide with lead burnt grid and be connected, constitute a rigidity box type construction, a hydraulic supporting device by its lifting of Driven by Hydraulic Cylinder is installed on the coke guiding locomotive car body below coke guide, be bearing in the bottom of coke guide when the discharging of the coke.

The advantage that the utility model is compared with prior art had is: 1, coke guide and lead the integral rigidity that the common rigidity box type construction that constitutes of burnt grid has improved coke guidance device has reduced sideshake amount and distortion; 2, the hydraulic supporting device that adopt supporting when the discharging of the coke, resets when not the discharging of the coke replaces rigid support means of the prior art, has thoroughly eliminated the jam phenomenon that thermal expansion causes, and coke guiding locomotive can normally be moved continuously; 3, improve production efficiency, reduced maintenance load.

Fig. 4 is the structural representation of coke guidance device in the prior art.

Fig. 5 is the B portion enlarged view of Fig. 4.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1,2 as can be known, the utility model coke guidance device mainly by upper rail 1, messenger 2, lead burnt grid 3, hydraulic drive mechanism 4, coke guide 5, hydraulic supporting device 6 and guiding mechanism 7 and form, be installed on the coke guiding locomotive car body 8.Leading burnt grid 3 is the lower opening frameworks that are welded by H shaped steel grid frame 3a and plain plate screen 3b.Coke guide 5 is fixed on vertical H shaped steel of grid frame 3a by bolt, and leads burnt grid 3 and constitutes a rigidity box type construction.Leading the upper end of burnt grid 3 hangs on upper rail 1 by messenger 2.Hydraulic drive mechanism 4 drives by leading box type construction that burnt grid 3 and coke guide 5 constitute with respect to coke oven coke outlet 9 forward-reverses.Hydraulic supporting device 6 is made up of oscillating motor 6a, connecting rod 6b and bogie wheel 6c, is installed on the coke guide 5 following coke guiding locomotive car bodies 8.Oscillating motor 6a drivening rod 6b action makes the bogie wheel 6c lifting that is installed on the connecting rod 6b, is bearing in the bottom of coke guide 5 or resets.

One guiding mechanism 7 is arranged between coke guide 5 and coke guiding locomotive car body 8, as shown in Figure 3, constitute by three guide rail 7b and three guide wheel 7a.A top tumbler 7a and a upper rail 7b are installed backward in proper order by the front end near coke oven coke outlet 9 in coke guide 5 bottoms, this top tumbler 7a extend between two parallel lower guideway 7b that are installed on hydraulic supporting device 6 both sides on the coke guiding locomotive car body 8, and upper rail 7b is between the two bottom tumbler 7a that are installed in two parallel lower guideway 7b rear portions on the coke guiding locomotive car body 8.Because the axis of guide wheel 7a is vertically disposed, can move up and down with respect to guide rail 7b, so 7 of liners play the guiding role, prevent that coke guidance device from tumbling, and the jam phenomenon that causes because of expansion can not occur.

When the discharging of the coke, hydraulic drive mechanism 4 drives this coke guidance device and advances, and makes to lead burnt grid 3 and be adjacent to coke oven coke outlet 9.The oscillating motor 6a drivening rod 6b action of hydraulic supporting device 6 is risen bogie wheel 6c, is bearing on the upper rail 7b of coke guide 5 bottom guiding devices 7, undertakes the weight of coke in the coke guide 5.At this moment, if the swell increment led after burnt grid 3 are heated is excessive, the load of oscillating motor 6a that makes hydraulic supporting device 6 is greater than the base load rating that normally discharges of the coke, then hydraulic efficiency system overflow, and the corresponding retraction of bogie wheel 6c is abdicated the expansion space, and equipment is shielded.After the discharging of the coke, hydraulic supporting device 6 descends, and abdicates the running space of liner 7, and coke guidance device resets.
