Description

Technical Field

[0001] The utility model relates to the technical field of transfer machines, and more specifically, to a trough box structure of a transfer machine bridge section. Background Technique

[0002] At present, the side plate chain path and the coal passing area of the trough box of the transfer machine bridge section adopt an integrated design (as shown below Figure 1 ), and this trough box structure of the transfer machine has the following disadvantages: 1. The damage of the trough box generally shows that the side plate chain path of the trough box is severely worn, and the upper left and right side plates are less worn. Using the same material and plate thickness causes material waste; 2. For the trough boxes of transfer machines in the same chain path space, due to the difference in coal passing volume in different coal mines, different height requirements are needed for the upper left and right side plates. It is necessary to design trough boxes of the transfer machine bridge section with different height dimensions, increasing the design workload and having a low standardization level; 3. During subsequent repair processes, for the trough boxes of transfer machines with severely worn side plates in the middle, bottom, and chain path areas that need to be scrapped, they are scrapped as a whole, while the upper left and right side plates have less wear and are also scrapped, resulting in greater waste.

[0003] Therefore, it is necessary to improve the existing technology. Content of the Utility Model

[0004] In order to overcome the deficiencies in the prior art, a trough box structure of a transfer machine bridge section with a split structure is provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] A trough box structure of a transfer machine bridge section includes a trough box bottom plate and trough box side plates. The trough box side plates are fixedly arranged on the left and right sides of the trough box bottom plate. The trough box side plates include lower trough box side plates and upper baffles arranged separately, and the upper baffles are inserted at the upper ends of the lower trough box side plates;

[0007] An upper connecting plate is fixedly arranged at the upper end of the lower trough box side plate. A positioning pin hole is penetrated through the upper connecting plate. A lower connecting plate is fixedly arranged at the lower end of the upper baffle. A fixing pin Ⅰ is fixedly arranged on the lower connecting plate. The positioning pin Ⅰ is inserted into the positioning pin hole, and there are at least two positioning pins Ⅰ and positioning pin holes;

[0008] Bolt connection holes are correspondingly arranged on the upper connecting plate and the lower connecting plate, and the upper connecting plate and the lower connecting plate are connected by bolts and nuts;

[0009] The wear resistance of the material of the lower trough box side plate is greater than that of the material of the upper baffle.

[0010] Preferably, end face plates are arranged at both ends of the lower trough box side plate and the upper baffle. A positioning hole is arranged on the end face plate at one end of the lower trough box side plate, and a positioning pin Ⅱ that cooperates with the positioning hole is arranged on the end face plate at the other end of the lower trough box side plate.

[0011] Preferably, the thickness of the side plate of the lower trough box is greater than the thickness of the upper baffle.

[0012] Preferably, the upper baffle is provided with specifications of various different heights.

[0013] Preferably, a middle plate is fixedly connected to the upper middle part of the side plate of the lower trough box, and a wing plate is fixedly connected to the upper part of the side plate of the lower trough box.

[0014] Preferably, the material of the side plate of the lower trough box is NM360, and the material of the upper baffle is Q345.

[0015] The beneficial effects of the present utility model compared with the prior art are as follows:

[0016] 1. The side plate of the lower trough box and the upper baffle of the present utility model adopt a split design, and the side plate of the lower trough box and the upper baffle adopt plates with different wear-resistant properties, which minimizes the material cost of the side plate of the trough box of the transfer rack bridge section. At the same time, it makes the selection of the plate match the wear resistance of the plate required by the actual wear.

[0017] 2. The upper baffle of the present utility model can be selected with specifications of different heights. Different customers only need to select the same trough box and baffle sizes of different heights, achieving the standardization of the design height and greatly reducing the workload of designers such as design and drawing.

[0018] 3. In the subsequent repair process of the present utility model, if the trough box is severely damaged and needs to be scrapped, since the wear of the upper baffle is small, the lower trough box can be directly scrapped and newly manufactured, and the upper baffle above can continue to be used after simple repair, avoiding the material waste caused by the need to scrap the whole trough box due to severe wear of the chain track before, and can reduce the repair cost of the trough box of the transfer machine to a certain extent, achieving the maximum utilization effect of materials.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] As Figures 1 to 5 shown, a trough box structure of a transfer machine frame bridge section includes a bottom plate 1 of the trough box and a side plate 2 of the trough box. The side plate 2 of the trough box is fixedly arranged on the left and right sides of the bottom plate 1 of the trough box. The side plate 2 of the trough box includes a separately arranged lower side plate 21 of the trough box and an upper baffle 22. The upper baffle 22 is inserted into the upper end of the lower side plate 21 of the trough box.

[0028] In order to facilitate the connection between the upper baffle 22 and the lower side plate 21 of the trough box, an upper connecting plate 23 is fixedly arranged at the upper end of the lower side plate 21 of the trough box. A positioning pin hole 24 is penetrated through the upper connecting plate 23. A lower connecting plate 25 is fixedly arranged at the lower end of the upper baffle 22. A fixed pin I 26 is fixedly arranged on the lower connecting plate 25. By inserting the fixed pin I 26 into the corresponding positioning pin hole 24, positioning is achieved. There are at least two fixed pins I 26 and positioning pin holes 24.

[0029] In order to facilitate the locking of the upper baffle 22 and the lower side plate 21 of the trough box, bolt connection holes 27 are correspondingly arranged on the upper connecting plate 23 and the lower connecting plate 25. Bolts are inserted into the bolt connection holes 27. The upper connecting plate 23 and the lower connecting plate 25 are connected by bolts and nuts.

[0030] The wear resistance of the material of the lower side plate 21 of the trough box is greater than that of the material of the upper baffle 22. Preferably, the lower side plate 21 of the trough box is made of NM360 or a material with higher wear resistance, and the material of the upper baffle 22 can be Q345.

[0031] Located to facilitate the butt joint of adjacent tank boxes, end panels 3 are provided at both ends of the lower tank box side plate 21 and the upper baffle 22.

To ensure that the end panels 3 of the lower tank box side plate 21 and the upper baffle 22 have the same connection dimension at the end face, after assembling and fastening the baffle and the tank box, the positioning hole 31 and the positioning pin II 32 need to be machined together.

[0032] Preferably, the thickness of the lower tank box side plate 21 is greater than the thickness of the upper baffle 22 to improve the service life of the lower tank box side plate 21.

[0033] The upper baffle 22 can be provided with various specifications of different heights, and different upper baffles 22 can be selected according to different required heights for assembling with the lower tank box side plate 21.
