Description

Technical Field

[0001] This invention relates to the field of kiln equipment technology, specifically a balancing top car machine for pushing kiln cars. Background Technology

[0002] Kiln cars are used to transport materials in and out of the kiln. Generally, kiln cars themselves have no driving power and run on tracks, propelled by a top-mounting machine. Existing top-mounting machines have the following problems: 1. The top-mounting machine is narrow and usually has a single top block, which leads to an unbalanced force on the kiln car when pushing it, easily damaging parts such as wheels; 2. Existing top-mounting machines are generally driven by a single hydraulic cylinder. After each kiln car is pushed, it is necessary to wait for the hydraulic cylinder to retract before pushing the next kiln car. This causes the kiln cars to move intermittently and not at a constant speed. On the one hand, the materials on the kiln car may sway due to inertia, and some products are easily damaged by bumps. On the other hand, the inability of the kiln cars to run continuously also affects the atmosphere inside the kiln and increases energy consumption. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the prior art and to provide a balancing top car machine for pushing kiln cars.

[0004] The specific solution of the present invention is: a balancing top car machine for pushing kiln cars, including a fixed support, the top of the fixed support is provided with three sets of tracks, the three sets of tracks are arranged side by side, each set of tracks is equipped with a top car, the top car A located in the middle is connected to a hydraulic cylinder A at one end, a connecting frame is provided between the two top cars B located on both sides, the connecting frame is connected to the hydraulic cylinder B, the top of the top car A is equipped with two top blocks A, the top of the two top cars B is equipped with one top block B, the two top blocks A are symmetrical about the center line of the fixed support, and the two top blocks B are symmetrical about the center line of the fixed support.

[0005] Furthermore, each set of tracks consists of two channel steels arranged opposite each other, with a guide beam in the middle of each channel steel, and the guide beam is arranged along the entire length of the channel steel.

[0006] Furthermore, both top car A and top car B are equipped with guide bearings on their sides, and the guide bearings roll along the guide beam.

[0007] Furthermore, the guide bearing includes a side guide bearing and a bottom guide bearing, the side guide bearing rolling along the side of the guide beam and the bottom guide bearing rolling along the bottom surface of the guide beam.

[0008] Furthermore, the width of the top vehicle A is greater than the width of the top vehicle B, and the distance between the two top blocks A is greater than 10cm.

[0009] The present invention has the following beneficial effects: by setting up top car A and top car B and two sets of oil cylinders, top car A and top car B alternately push, thereby making the kiln car run continuously and at a uniform speed, and the kiln car is subjected to balanced forces, reducing the damage to the corresponding parts.

[0011] See Figure 1-2 This embodiment is a balancing top car machine for pushing kiln cars, including a fixed support 1. The top of the fixed support 1 is provided with three sets of rails 2, which are arranged side by side. Each set of rails 2 is equipped with a top car. The top car A7 in the middle is connected to a hydraulic cylinder A at one end. A connecting frame 9 is provided between the two top cars B5 on both sides. The connecting frame 9 is connected to a hydraulic cylinder B. The top of the top car A7 is equipped with two top blocks A8, and the top of each of the two top cars B5 is equipped with a top block B6. The two top blocks A8 are symmetrical about the center line of the fixed support 1, and the two top blocks B6 are symmetrical about the center line of the fixed support 1.

[0012] Furthermore, each set of tracks 2 consists of two channel steels arranged opposite each other, with guide beams 3 located in the middle of each channel steel, and the guide beams 3 are arranged along the entire length of the channel steel.

[0013] Furthermore, both the top car A7 and the top car B5 are equipped with guide bearings on their sides, and the guide bearings roll along the guide beam 3.

[0014] Furthermore, the guide bearing includes a side guide bearing 4 and a lower guide bearing 10. The side guide bearing 4 rolls along the side of the guide beam 3, and the lower guide bearing 10 rolls along the bottom surface of the guide beam 3.

[0015] Furthermore, the width of the top car A7 is greater than the width of the top car B5, and the distance between the two top blocks A8 is greater than 10cm.

[0016] When the invention is in operation, the top car A7 and two top cars B5 operate alternately. When the hydraulic cylinder drives the top car A7 to push the kiln car, the hydraulic cylinder of the top car B5 is in the retracted state. When the top car A7 reaches the limit position of its stroke, the hydraulic cylinder drives the top car A7 to return. At the same time, the hydraulic cylinder of the top car B5 drives the two top cars B5 to push the next kiln car synchronously through the connecting frame 9. The kiln cars are closely connected and the thrust is transmitted, thereby realizing the uniform speed of the kiln cars on the entire track 2.

[0017] In addition, since there are two top blocks A8 that are spaced a certain distance apart on the top car A7, the kiln car can be balanced on both sides when it is pushed; and when the top car B5 moves, the kiln car is simultaneously pushed by the two top blocks B6 on both sides, which can also be balanced.
