[ detailed description ] embodiments

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses a swift current board structure of sinter pouring box, as shown in figure 1, figure 2, including being used for laying on the pouring box support, the bottom plate 4 that the slope set up, longitudinal separation is provided with a plurality of baffles 2 on the bottom plate 4, and every baffle 2 all extends to the bottom from the top of bottom plate 4, and two adjacent baffles 2 all can be dismantled has antifriction plate 1. All seted up a plurality of groove holes on every antifriction plate 1, every groove hole all is used for when the sintering deposit slips from it, storage sintering slay to produce the friction through sintering slay and sintering deposit, reduce the wearing and tearing of sintering deposit to antifriction plate 1. In the embodiment, 4 baffles 2, 3 wear- resistant plates 1 and 4 baffles 2 are welded with the bottom plate 4.

The wear-resisting plates with consistent shapes and structures are arranged on the bottom plate, so that the wear-resisting plates can be prevented from being broken under the impact of large blocks of sintering ores, the mounting positions of the wear-resisting plates can be replaced according to the abrasion conditions of all the parts, the utilization rate of the wear-resisting plates is improved, the service cycle of the slide carriage is prolonged, and frequent replacement is avoided; still through seting up the groove hole on the antifriction plate, when collecting sintering slay, make sintering deposit and the sintering slay in the groove hole rub, protect the antifriction plate, further prolong the life cycle of carriage apron.

In the embodiment of the present invention, as shown in fig. 3 and 4, two sides of each wear plate 1 and the connecting portion of the baffle 2 are both provided with the recessed portion 6 in an inward recessed manner, the recessed portion 6 is identical to the side shape of the baffle 2, and the baffle 2 is used for being embedded into the recessed portion 6, so as to fix the wear plates 1 and the baffle 2. Through-hole 7 has all been seted up to side of baffle 2 and antifriction plate 1, and through-hole 7 is used for fixing bolt 3 to pass.

In this embodiment, 12 sets of fixing bolts are used, and 3 wear plates 1 are connected with 4 baffles through 12 sets of fixing bolts. In order to facilitate installation and avoid machining, in the embodiment, the wear-resisting plate 1 is subjected to lost foam casting, and after demolding, the outer contour of the wear-resisting plate 1 and the periphery of the through hole 7 need to be polished.

Through being equipped with depressed part 6 in the both sides at antifriction plate 1, when baffle 2 both sides all had antifriction plate 1, baffle 2 imbeds in the space that two depressed parts 6 formed, can make a plurality of antifriction plate 1 steadily arrange bottom plate 4 on, can not produce the gap. Both of these are connected in such a way that the wear plate 1 is laid more smoothly on the bed plate 4. If the wear-resisting plate 1 is laid smoothly, when sinter ore (generally weighing 10 tons) falls from the trolley, the wear-resisting plate 1 can be smashed to deform and even fall, so that production is influenced and accidents are caused.

The utility model discloses in, antifriction plate 1 is the axisymmetric structure, and a plurality of groove holes become array and arrange. By forming the groove on the wear plate 1, the amount of material used for the wear plate 1 and the weight of the wear plate 1 can be saved as much as possible, in addition to storing sintering slag. The axisymmetric structure can realize the mutual replacement of the wear-resisting plates 1. The groove hole becomes array and arranges in order to increase the balance of antifriction plate 1, moreover, when carrying out the exchange in position to each antifriction plate 1, avoids laying because the groove hole is different, and each part frictional force that arouses is uneven, and then avoids arousing the problem of sintering deposit off tracking.

The embodiment of the utility model provides an in, consider that single tooth roller crusher carriage apron belongs to the depletive device, for change and maintenance be convenient for, design its fixed mode on guide box support for the suspension type. A plurality of hooks 5 are arranged below the bottom plate 4, and each hook 5 is used for being connected with a material pouring box support. Set up 4 couples in this embodiment, weld the lower surface at bottom plate 4 respectively, and then hang with the support.

In addition, in this embodiment, the slide carriage needs to have good wear resistance during operation, and the wear resistance generally requires that the material has a large hardness. Moreover, the carriage is required to have good impact resistance against a large weight of sintered ore, and the impact resistance requires a material having good toughness, and it is very difficult to satisfy both of these criteria for the same material. To solve this conflict, the material of the slide is designed as a composite combination of two materials in this embodiment.

In addition, in this embodiment, carbon dioxide arc welding is adopted between the baffle 2, the hook 5 and the bottom plate 4, and a groove is formed before welding, so that welding is required to be firm and reliable, and measures need to be taken in the welding process to prevent the baffle, the bottom plate and the hook from deforming. The first installation can be assembled in advance. If the situation of untimely fitting occurs in the assembling process, the problem can be eliminated by grinding. When the hanger is integrally hung, the hanger is directly hung in a hanging groove preset on the support. When the position is locally replaced or adjusted, the bolt can be detached.

In this embodiment, the wear-resistant plate 1 is cast by using a heat-resistant wear-resistant alloy material, and the high temperature resistance and wear resistance of the wear-resistant plate are mainly considered from the material selection, so that the wear-resistant plate 1 is designed to be 3 blocks of combination to effectively prevent the wear-resistant plate 1 from being broken when the shape is too large and is easy to break under the action of strong impact force. In order to reduce the material consumption, 6 groove pits are designed on each wear-resisting plate 1, the material consumption is reduced as much as possible on the premise of meeting the structural requirements, and the groove pits are filled with sintering ores in the use process, so that the effect of protecting the wear-resisting plates 1 due to the fact that the sintering ores are rubbed with the sintering ores is achieved, and the buffer effect of the falling sintering ores is achieved. The abrasion degree of the slide carriage of the composite single-tooth-roller crusher at different positions is different due to the influence of the falling position of the sinter, and 3 wear-resistant grooves can be installed in a rotating mode for 180 degrees and can be exchanged in position, so that the service life of the composite single-tooth-roller crusher is greatly prolonged, and the operation cost is reduced. Adopt fixing bolt 3 to be connected between antifriction plate 1 and the baffle 2, can realize easily adjusting the position each other or changing antifriction plate 1's part between the antifriction plate 1. In order to ensure the integral shock resistance and the weldability among materials of the slide carriage of the composite single-tooth-roller crusher, the materials of the baffle 2, the bottom plate 4 and the hook 5 are all selected to be NM400 steel plates. Each hook 5 is provided with a round hole for hoisting and installing and fixing the slide carriage of the composite single-tooth-roller crusher.

Generally, the slide carriage of the composite single-tooth-roller crusher meets the requirements of high-temperature wear resistance and strong impact resistance, can be partially replaced or integrally replaced, and can be used in a position adjusting mode.
