Description

Technical Field

[0001] The utility model belongs to the technical field of material transport vehicles, in particular to a material transport vehicle for a vertical aluminum alloy heat treatment furnace. Background Art

[0002] At present, most of the material transport vehicles for vertical aluminum alloy heat treatment furnaces are made of steel sections welded into a rectangular frame. A drive shaft and guide wheels are installed under the frame, and a material frame bracket is installed above the frame to provide stable and reliable support for the material frame. The material frame bracket is a disc-shaped structure, which is rolled from channel steel and has reinforcing ribs in the middle. The entire bracket is directly welded to the material transport vehicle.

[0003] However, the existing material frame bracket is a disc-shaped structure, made of channel steel with reinforcing ribs in the middle. The entire bracket is directly welded to the material transport vehicle, which has two major defects: First, it is difficult to position the material frame when hoisting it. The material frame needs to be placed on the bracket by visual inspection, and it needs to be manually adjusted many times to make the material frame stable; second, the bracket is rigidly connected to the material transport vehicle body, and the impact generated when hoisting the material frame is very large, which will cause the wheel axle of the frame to break after a long time. In addition, the frame will bend and deform under the gravity of the water tank, resulting in a decrease in the friction between the drive wheel and the heavy rail, causing the wheels of the material transport vehicle to slip and be unable to move when running on the heavy rail, thereby greatly reducing the transportation efficiency.

Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] The utility model embodiment provides a material transport vehicle for a vertical aluminum alloy heat treatment furnace, Figure 1-6As shown, the material transport vehicle is used to store and transport the material frame 1.

[0034] In some embodiments, the material transport vehicle for the vertical aluminum alloy heat treatment furnace provided by the utility model is mainly used for transporting workpieces back and forth and completing quenching of the workpieces.

[0035] Furthermore, the buffer assembly 33 includes a spring seat 331, a spring rod 333 and a spring 334. One end of the spring seat 331 is connected to the bottom bracket 32, and the other end of the spring seat 331 is provided with a first sleeve 332; one end of the spring rod 333 is connected to the bracket body 31, and the other end of the spring rod 333 is inserted into the first sleeve 332; one end of the spring 334 is connected to the spring rod 333, and the other end of the spring 334 is connected to the spring seat 331. By setting the buffer assembly 33, the spring rod 333 is inserted into the first sleeve 332 of the spring seat 331, so that the spring rod 333 and the spring seat 331 are connected through the spring 334.

By providing the limiting assembly 35, the limiting column 353 is inserted into the second sleeve 352 of the limiting seat 351, so that the limiting assembly 35 can move with the vertical movement of the buffer assembly 33.

[0039] Furthermore, the length of the limiting column 353 is the same as that of the limiting seat 351 , and the distance between the bracket body 31 and the bottom bracket 32 ​​is greater than the length of the limiting column 353 .

[0040] Furthermore, the limiting assembly 35 also includes a limiting rod 354 , one end of which is provided with an external thread, the limiting column 353 is provided with a threaded hole, and one end of the limiting rod 354 provided with the external thread is threadedly connected to the limiting column 353 .

[0041] Furthermore, a limiting groove 355 is provided on the second sleeve 352 , and a limiting rod 354 is inserted into the limiting groove 355 , so as to move the limiting rod 354 up and down along the limiting groove 355 .

[0042] In some embodiments, a limit groove 355 and a limit rod 354 are provided in the limit assembly 35, and the width of the limit rod 354 is the same as the width of the limit groove 355, which can effectively prevent the bracket body 31 from rotating in the circumferential direction when the material frame 1 is suspended on the bracket body 31, thereby further achieving the stability of the suspended material frame 1.

[0043] Furthermore, the material transport vehicle for the vertical aluminum alloy heat treatment furnace also includes a heavy rail 4, a plurality of running wheels 5, a plurality of drive shafts 6 and a plurality of chains 7. The plurality of running wheels 5 are respectively arranged on both sides of the vehicle body 2, and the plurality of running wheels 5 are arranged on the heavy rail 4 and move along the heavy rail 4; the drive shaft 6 is arranged between the two running wheels 5 on both sides of the vehicle body 2, and two sprockets 8 are arranged in the middle of the drive shaft 6; the chain 7 connects the two corresponding sprockets 8 on the two adjacent drive shafts 6.

[0044] Furthermore, the material transport vehicle for the vertical aluminum alloy heat treatment furnace also includes a water tank 10 and a reducer 9. The water tank 10 is arranged on the vehicle body 2 to cool the workpiece; the reducer 9 is connected to the drive shaft 6 to drive the drive shaft 6 to rotate.

[0045] The utility model arranges two sprockets 8 in the middle of the driving shaft 6, and connects the two corresponding sprockets 8 on the two adjacent driving shafts 6 through the chain 7, so that the two adjacent driving shafts 6 can be driven by the chain 7, and the power output by the reducer 9 is effectively transmitted to all the running wheels 5 in a balanced manner, which effectively solves the problem that the body 2 of the material transport vehicle for the vertical aluminum alloy heat treatment furnace is bent and deformed due to excessive gravity, resulting in a reduction in the friction between the running wheels 5 and the heavy rail 4, causing the running wheels 5 to slip and be unable to move.

[0046] In some embodiments, only two chains can be used to connect the two adjacent sprockets at one end of the material transport vehicle close to the reducer, or multiple chains can be used to connect the other two adjacent sprockets on the material transport vehicle according to actual conditions, so as to effectively achieve balanced transmission of the power output of the reducer to all wheels.

[0047] The working process of the above-mentioned material transport vehicle for the vertical aluminum alloy heat treatment furnace is as follows:

[0048] The prepared material frame 1 is quickly and stably placed on the bracket body 31 by hoisting, wherein the positioning hole 11 on the material frame 1 is matched with the positioning pin 341, and the positioning plate 342 fixes the material frame 1 around. During production, the material frame 1 on the material transport vehicle is moved to the bottom of the furnace cover, the furnace door is opened, the hook is lowered to lift the material frame 1 into the furnace, and the furnace door is closed for heating. During quenching, the water tank 10 on the material transport vehicle is first moved to the bottom of the furnace cover. When the water tank 10 is transferred, the vehicle body 2 may bend and deform under the gravity of the water tank 10, causing the friction between the running wheel 5 and the heavy rail 4 to decrease, causing the running wheel 5 to slip and be unable to move. At this time, the chain 7 on the two adjacent drive shafts 6 is used for transmission, so as to control the sprocket 8 to drive the power output of the reducer 9 to be evenly transmitted to all the running wheels 5, so as to move the water tank 10 to the bottom of the furnace cover, open the furnace door at this time, lower the hook, quench the material frame 1 into the water in the water tank 10, and complete the quenching of the workpiece in the material frame 1.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
