Description

A drive device for a vertical kiln car Technical Field

[0001] This utility model relates to the field of kiln car drive technology, and in particular to a drive device for a vertical kiln car. Background Technology

[0002] Vertical kilns are commonly used thermal equipment in industrial production, and kiln cars are key components in vertical kilns that carry and transport materials. The driving of kiln cars typically requires precise, stable, and adjustable drive systems to adapt to different production processes and kiln car conditions.

[0003] In existing vertical kiln car drive systems, some devices employ cam mechanisms for transmission to achieve the reciprocating motion of the kiln car. However, cam-based drive systems typically suffer from the following shortcomings: First, once the cam's profile curve is designed, its driving stroke and motion characteristics (such as speed and acceleration curves) are relatively fixed, making it difficult to flexibly adjust according to different kiln car specifications, material loading conditions, or process requirements. Changing the stroke or motion pattern often necessitates redesigning and replacing the cam, resulting in poor versatility and flexibility. Second, the contact between the cam and the follower is usually point or line contact, which is prone to wear under high loads or prolonged operation, leading to decreased motion accuracy and higher maintenance and replacement costs. Furthermore, cam mechanisms become extremely complex or difficult to implement when achieving complex adjustment functions, such as precise adjustment of the driving height, fine-tuning of the lateral position, or controllable clamping force.

[0004] Therefore, existing vertical kiln car drive devices, especially those using traditional cam drives, still suffer from problems such as insufficient flexibility in adjustment, complex structure, difficulty in guaranteeing accuracy after wear, weak adaptability, and lack of effective buffering in terms of the flexibility of the pushing stroke, the precise adjustability of the pushing height, the adaptability of the lateral position, the control of the clamping force, and the reliability and economy of long-term operation. For example, the thrust point of some drive devices is fixed or difficult to adjust, making it difficult to adapt to kiln cars of different sizes or positions; or the height adjustment mechanism is complex and lacks stability; or there is a lack of buffering when contacting the kiln car, which easily causes impact. Therefore, there is a need for a vertical kiln car drive device with optimized structure, convenient adjustment, reliable operation, and the ability to overcome the shortcomings of traditional cam mechanisms.

Detailed Implementation

[0043] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0044] As shown in Figures 1-4, this utility model provides a driving device for a vertical kiln car, including a hydraulic cylinder 1, the output end of which is fixedly connected to a horizontal plate 2. Two mounting plates 3 are symmetrically fixed on both sides of the horizontal plate 2, enhancing the stability of the structure.

[0045] An adjustment mechanism 4 is mounted on one of the mounting plates 3. This adjustment mechanism 4 is used to fine-tune the horizontal position of the drive unit docking with the kiln car. The adjustment mechanism 4 includes an adjustment motor 41, the output of which is connected to and drives a screw 42. The two ends of the screw 42 are respectively rotatably engaged with the two mounting plates 3, for example, through bearing seats. A moving block 43 is threadedly fitted onto the screw 42. When the adjustment motor 41 drives the screw 42 to rotate, the moving block 43 moves left and right along the axial direction of the screw 42. A connecting column 44 is horizontally fixed to the moving block 43, and a push plate 45 is vertically fixed to the end of the connecting column 44. In this way, by controlling the start, stop, and direction of the adjustment motor 41, the horizontal position of the push plate 45 can be precisely adjusted.

[0046] An elongating clamping assembly 5 is mounted on push plate 45 and is used to adjust the vertical height of push plate 56, which contacts the kiln car. The elongating clamping assembly 5 includes a hollow outer clamping plate 51, which is fixed to the surface of push plate 45. An adjusting motor 52 is horizontally mounted inside the outer clamping plate 51. A screw 53 is driven to rotate by the adjusting motor 52 and rotates in conjunction with the outer clamping plate 51, for example, via a bearing. A limiting plate 54 is threaded onto the screw 53 and can slide up and down along the axial direction of the screw 53. At least two sets of elongating rods 55 have their upper ends passing through the outer clamping plate 51 and fixed to the push plate 56, and their lower ends fixedly connected to the limiting plate 54. When the adjusting motor 52 drives the screw 53 to rotate, the limiting plate 54 moves up and down along the screw 53, thereby causing the elongating rods 55 and the push plate 56 to rise and fall, thus adjusting the extension length of the push plate 56.

[0047] To accommodate kiln cars of varying heights or overall height deviations caused by uneven ground or track settlement, this device preferably includes a lifting assembly 6, which is located at the bottom of the hydraulic cylinder 1. The lifting assembly 6 comprises a base 61 and a mounting base 62, with the hydraulic cylinder 1 fixed to the mounting base 62. The base 61 and mounting base 62 are linked together by an upper X-shaped rod 63 and a lower X-shaped rod 64, forming a scissor-type lifting structure. At least two sets of lifting blocks 65 are rotatably connected to the corresponding ends of the upper X-shaped rod 63 and the lower X-shaped rod 64, respectively. A lifting screw 66 passes between the corresponding two sets of lifting blocks 65, with one end rotatably connected to one lifting block 65 and the other end threadedly connected to the other lifting block 65. Slide grooves 67 are respectively formed on the bottom of the mounting base 62 and the upper part of the base 61 on the same side, allowing the other ends of the upper X-shaped rod 63 and the lower X-shaped rod 64 to slide within the slide grooves 67 via sliders 68. The lifting screw 66 is connected to a lifting motor 69 at its drive end, and the lifting motor 69 is fixed to the outside of the lifting block 65 to which it is connected. When the lifting motor 69 drives the lifting screw 66 to rotate, the distance between the two lifting blocks 65 changes, thereby causing the X-shaped rod to unfold or retract, realizing the lifting of the mounting base 62 relative to the base 61, and thus adjusting the working height of the entire drive device.

[0048] To provide cushioning and reduce impact when driving the kiln car, an elastic component 7 is preferably provided between the pusher plate 45 and the corresponding pusher plate 56. As shown in Figure 4, the elastic component 7 may include a clamping plate 71, which is fixedly connected to the insert rod 72. A guide cylinder 73 is sleeved on the outside of the insert rod 72 and is fixedly connected to or integrated with the pusher plate 45. A spring 74 is disposed inside the guide cylinder 73, with its two ends fixed or abutting against the bottom of the guide cylinder 73 and the insert rod 72, respectively. When the pusher plate 56 is subjected to force, the insert rod 72 can compress the spring 74 inside the guide cylinder 73 to achieve cushioning.

[0049] To further improve the smoothness and guiding accuracy of the movement of the moving block 43 in the adjusting mechanism 4, a guide rod 8 can be set between the two mounting plates 3, parallel to the screw 42, and the moving block 43 can be slidably sleeved on the guide rod 8. In this way, when the moving block 43 moves under the drive of the screw 42, it is simultaneously guided and constrained by the guide rod 8, making the movement more stable and reliable.

[0050] Working principle:

[0051] Start the lifting motor 69 to drive the lifting screw 66 to rotate. The scissor structure of the lifting assembly 6 causes the mounting base 62, together with the hydraulic cylinder 1 on it and the entire trolley mechanism, to rise or fall to adapt to the approximate height of the kiln car.

[0052] Start the adjusting motor 41, drive the screw 42 to rotate, so that the moving block 43 moves left and right along the screw 42 and the guide rod 8, thereby driving the push plate 45 and the elongated clamping assembly 5 on it to make precise horizontal position adjustment, so that the push plate 56 is aligned with the predetermined push top position of the kiln car.

[0053] Start the adjustment motor 52, drive the screw 53 to rotate, causing the limit plate 54 to move up and down, which in turn drives the extension rod 55 and the push plate 56 to rise and fall, precisely adjusting the extension length of the push plate 56.

[0054] Hydraulic cylinder 1 extends, pushing the horizontal plate 2 and the entire trolley mechanism forward. The second pusher plate 56 contacts the kiln car, and the elastic component 7 provides cushioning at the moment of contact and during the pushing process. Hydraulic cylinder 1 continuously outputs power to push or pull the kiln car into or out of the vertical kiln.

[0055] The drive device for the vertical kiln car of this utility model achieves precise control and good adaptability of the kiln car driving process through the coordinated action of various components, thereby improving the level of automation and operational reliability.
