Novel fixing structure of trolley breast board
Technical Field
The utility model relates to a sintering machine technical field, concretely relates to new fixed knot of platform truck breast board constructs.
Background
Sintering machines are commonly used in the metallurgical industry as roasting equipment. At present, the trolley breast boards on two sides of a sintering machine are connected by bolts, and because the trolley breast boards are circularly operated at the high temperature of 1100 ℃ for a long time and are influenced by thermal expansion and cold contraction, bolts connecting the breast boards on the two sides are elongated, and further the bolts are loosened; after the bolts are loosened, the breast board can incline (generally outwards incline), so that the breast board leaks air; if the inclination amplitude is too large, the workpiece can be scratched with an ignition furnace or other equipment, and other equipment can be damaged. In order to ensure that the breast board does not incline, the trolley breast board bolt needs to be fastened regularly. The sintering machine is provided with a plurality of trolley bodies, a lower breast board and two upper breast boards are arranged on two sides of each trolley body, the lower breast boards and the trolley bodies are fixed by four bolts, two upper breast boards are arranged above each lower breast board, and each upper breast board and each lower breast board are fixed by two bolts respectively, so that the quantity of the bolts is large, and the bolt fastening work is heavy; in addition, the bolts work in a high-temperature environment, most of the bolts are difficult to tighten, and therefore the bolts which are not tightened are required to be cut by a mechanic and replaced again. Accordingly, a new structure is needed to replace bolted trolley fenders.
SUMMERY OF THE UTILITY MODEL
Therefore, the utility model provides a new fixed knot of platform truck breast board constructs to solve foretell technical problem.
In order to achieve the above object, the present invention provides the following technical solutions:
a novel fixing structure of a trolley sideboard comprises a dovetail groove and a dovetail body matched with the dovetail groove, wherein the dovetail groove and the dovetail body are arranged along the length direction; one of the trolley body or the lower breast board is provided with the dovetail groove, and the other is provided with the Yan Weiti; one of the lower sideboard or the upper sideboard is provided with the dovetail groove, and the other is provided with the dovetail body.
The dovetail groove is characterized by further comprising a positioning pin, wherein a positioning hole is formed in the side portion of the junction of the Yan Weiti and the dovetail groove, and the positioning pin penetrates through the positioning hole to prevent the dovetail body from sliding along the dovetail groove.
Furthermore, the positioning hole and the positioning pin are both in a cone frustum shape, and the diameter of the inner end of the cone frustum is smaller than that of the outer end of the cone frustum.
Further, the inner end diameter of the cone frustum is 12mm, and the outer end diameter is 14mm.
Furthermore, the width of the notch of the dovetail groove and the width of the root of the dovetail body are both 25mm.
The utility model has the advantages of as follows:
utilize dovetail and the forked tail body of looks adaptation to replace the bolt, no longer use the bolt at all, consequently do not just have the high temperature environment to make the bolt elongated, the not hard up condition of bolt, just do not have the fence problem that leaks out and incline seriously yet, the condition that the equipment was damaged because of the fence slope more can not appear, so just need not carry out tedious regular fastening work again at all, just also do not have simultaneously and be difficult to tightly move, cut off the bolt, change the problem of bolt.

Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the present specification, the terms "upper", "lower", "left", "right", "middle", and the like are used for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.
Example 1
As shown in fig. 1 to 3, embodiment 1 provides a new fixing structure of a trolley sideboard, wherein dovetail grooves 4 are processed at positions where the sideboard 2 is installed at the left and right sides of the trolley body 1, a dovetail body 5 is processed below the sideboard 2, another dovetail groove 4 is processed above the sideboard 2, the dovetail body 5 is processed below the sideboard 3, and the dovetail grooves 4 and the dovetail bodies 5 are matched and are all arranged along the front and back direction (called as the length direction). Receive the influence of breast board height, weight, dovetail 5 need possess sufficient intensity and just can replace original bolt, and in a certain model, the width of the notch of dovetail 4 and dovetail 5's root is 25mm, and under this width condition, dovetail 5's intensity can obtain guaranteeing, avoids the breast board to take place to incline.
Positioning holes (not shown or marked) are formed in the side portions of the trolley body 1 and the side portions of the upper edge of the upper fence 3, the positioning holes penetrate through the joint of the dovetail body 5 and the dovetail groove 4, and a positioning pin 6 is inserted into the positioning holes, so that the dovetail body 5 is prevented from sliding along the dovetail groove 4. Generally, a lower breast board 2 is arranged on each of the left side and the right side of a trolley body 1, two upper breast boards 3 are arranged on each of the lower breast boards 2, two positioning holes are arranged at the joint of a dovetail body 5 of the trolley body 1 and the lower breast board 2 and a dovetail groove 4 at intervals, and two positioning pins 6 are correspondingly inserted into the two positioning holes; a positioning hole is formed in the joint of the dovetail body 5 of the upper breast board 3 and the lower breast board 2 and the dovetail groove 4, and a positioning pin 6 is correspondingly inserted; therefore, one trolley body 1 corresponds to two lower sideboard 2, four upper sideboard 3, total 8 positioning pins 6. The positioning hole and the positioning pin 6 are both in a cone frustum shape, and the diameter of the inner end of the cone frustum is smaller than that of the outer end; the diameter of the inner end of the cone frustum is 12mm, and the diameter of the outer end of the cone frustum is 14mm; a threaded hole (not shown or marked in the figures) is formed in the outer end of the positioning pin 6, and a screw is selected to pull out the positioning pin 6 during disassembly.
Utilize dovetail 4 and the forked tail body 5 of looks adaptation to replace the bolt, no longer use the bolt at all, consequently do not just have high temperature environment and make the bolt elongated, the bolt not hard up the condition, just also do not have the fence problem that leaks out and incline seriously, the condition that the equipment was damaged because of the fence slope more can not appear, so just need not carry out tedious regular fastening work again at all, just also do not have simultaneously and be difficult to tightly move, cut off the bolt, change the problem of bolt.
Example 2
As shown in fig. 4, the second new fixing structure of the platform truck sideboard is provided in the embodiment 2, which is basically the same as the embodiment 1, except that it is inconvenient to machine the dovetail groove 4 or the dovetail body 5 on the machined platform truck body 1, at this time, the dovetail body 5 is machined in the factory, and the dovetail body 5 is welded on the platform truck body 1; correspondingly, a dovetail groove 4 is processed on the processed lower fence 2. The advantages of this structure are the same as those of embodiment 1, and can be applied to the old carriage body 1 (the processed carriage body 1).
Example 3
As shown in fig. 5, embodiment 3 provides a third new fixing structure of the bogie breast board, which is basically the same as that of embodiment 1 or 2, except that a dovetail groove 4 is formed below the upper breast board 3, and a dovetail body 5 is formed above the lower breast board 2.
