Description

Technical Field

[0001] This invention belongs to the technical field of engineering machinery equipment parts, specifically relating to a limiting device for a tilting mechanism. Background Technology

[0002] Currently, there are many types of construction machinery, engineering vehicles, sanitation vehicles, and modified vehicles. Most of these devices have mechanisms or housings that can be tilted by hydraulic cylinders. With use, various malfunctions can occur. When repairing these malfunctions, the hydraulic cylinders are used to lift the tilting mechanism or housing, allowing maintenance personnel to enter the equipment or vehicle for inspection and repair. However, prolonged maintenance can lead to pressure loss and oil leaks in the hydraulic cylinders and their hydraulic systems, making it impossible to maintain the tilted state for extended periods. Therefore, a tilting limit device is needed to improve safety and reliability. Currently, a support rod is used. When the tilting structure or housing reaches the predetermined position, the support rod is manually raised and secured to the locking block of the tilting structure or housing, forming a triangle with the tilting mechanism or housing, base, or frame for stability.

[0003] Currently, a single support rod is used. When the tilting structure or housing reaches the predetermined position, the support rod is manually tilted and erected, locking onto the tilting structure or housing block, forming a triangle with the tilting mechanism, housing, base, or frame for stability. When maintenance is needed, the housing still needs to be tilted to the predetermined position using a hydraulic cylinder. Due to structural limitations, the support rod cannot be placed on the outside, requiring manual entry or partial entry into the tilting mechanism's stroke to erect it. In the event of a malfunction, the entire vehicle or equipment system may become unstable, potentially causing safety issues. Furthermore, the support rod is heavy and inconvenient for manual tilting and erection. The structure is large, and the long travel distance occupies significant space. To address these problems, this invention provides a limiting device for the tilting mechanism. It is simple in structure, occupies little space, and is low in cost; operation is simple, eliminating the need for manual entry into the tilting mechanism's stroke, thus improving the safety of manual operation. Summary of the Invention

[0004] The purpose of this invention is to provide a limiting device for a flipping mechanism, so as to solve the problems mentioned in the background art, which are safety hazards and inconveniences caused by the need for manual entry into the stroke of the flipping mechanism when using a support rod for limiting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a limiting device for a flipping mechanism, comprising a base; the base is provided with a flipping mechanism and a limiting mechanism at its front end, the limiting mechanism being located on one side of the flipping mechanism; the flipping mechanism includes a sliding rod, a flipping component, and a locking plate; the limiting mechanism includes a placement hole, a limiting hole, and a sliding groove.

[0006] By adopting the above scheme, the limiting mechanism is set on one side of the flipping mechanism, close to the flipping shaft of the flipping mechanism. The linkage design between the limiting mechanism and the flipping mechanism reduces the travel radius. This design is simple and does not require a large space on the base. In normal operation, the limiting bolt is inserted into the placement hole. The limiting bolt is always outside the working stroke of the sliding rod, so the limiting mechanism does not work under normal conditions. In fault repair, the limiting bolt is inserted into the limiting hole to stop the reciprocating movement of the sliding rod and play a limiting role. After the fault is repaired, the limiting bolt is inserted back into the placement hole to restore normal operation. This design is simple to operate. The opening and closing of the device is achieved by limiting the travel of the sliding rod. There is no need for manual operation of the support rod, avoiding manual entry into the flipping mechanism and improving work safety.

[0007] In a preferred embodiment, a flipping seat is fixedly installed at the front end of the base, and the flipping mechanism is connected to the flipping seat via a flipping shaft, wherein the flipping mechanism and the flipping shaft are rotatably connected.

[0008] In a preferred embodiment, a limiting seat is fixedly installed at the front end of the base. The limiting seat is located on one side of the flip base. The limiting mechanism is connected to the limiting seat through a limiting shaft, and the limiting mechanism and the limiting shaft are rotatably connected.

[0009] In a preferred embodiment, the placement hole and the limiting hole are both located above the limiting mechanism, and the placement hole and the limiting hole are both on the same horizontal line and are the same size.

[0010] In a preferred embodiment, the sliding groove is formed on one side of the limiting mechanism and both ends of the sliding groove are arc-shaped.

[0011] In a preferred embodiment, the flipping assembly is rotatably mounted on the outside of the flipping shaft, and the sliding rod is fixedly mounted inside the flipping assembly by a clamping plate, with one end of the sliding rod extending out of the flipping assembly.

[0012] In a preferred embodiment, one end of the sliding rod extends into the sliding groove, and a baffle is connected to the extended end of the sliding rod. The radius of the baffle is larger than that of the sliding rod to limit its movement.

[0013] In a preferred embodiment, the placement hole and the limiting hole are respectively inserted with limiting bolts in the normal working state and the fault maintenance state. In the fault maintenance state, the limiting bolts restrict the reciprocating movement of the sliding rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The limiting device of this flipping mechanism is designed by setting the limiting mechanism on one side of the flipping mechanism, with the limiting mechanism close to the flipping shaft of the flipping mechanism. The limiting mechanism and the flipping mechanism are linked together to reduce the travel radius. This design is simple and does not require a large space on the base. This type of tilting mechanism's limiting device works by inserting a limiting bolt into the placement hole during normal operation. The limiting bolt is always outside the working stroke of the sliding rod, so the limiting mechanism does not work under normal conditions. During fault repair, the limiting bolt is inserted into the limiting hole to prevent the reciprocating movement of the sliding rod, thus limiting the movement. After the fault is repaired, the limiting bolt is inserted back into the placement hole to restore normal operation. This design is simple to operate, and the opening and closing of the device is achieved by limiting the stroke of the sliding rod. There is no need for manual operation of the support rod, avoiding manual entry into the tilting mechanism and improving work safety. Attached Figure Description

[0017] The present invention will be further described below with reference to embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please see Figure 1-5 The present invention provides a limiting device for a flipping mechanism, comprising a base 1, a flipping mechanism 5, and a limiting mechanism 6.

[0020] like Figure 1As shown, the base 1 is connected to the limiting seat 2 and the flipping seat 3 at the front end. The limiting seat 2 and the flipping seat 3 are respectively connected to the limiting shaft 9 and the flipping shaft 4. The flipping mechanism 5 is rotatably installed on the outside of the flipping shaft 4, and the limiting mechanism 6 is rotatably installed on the outside of the limiting shaft 9, so that the flipping mechanism 5 can rotate around the flipping shaft 4 and the limiting mechanism 6 can rotate around the limiting shaft 9.

[0021] like Figure 2-3 As shown, the flipping mechanism 5 includes a sliding rod 51, a flipping assembly 52, and a locking plate 53. The locking plate 53 is used to fix the sliding rod 51 inside the flipping assembly 52. ​​One end of the sliding rod 51 extends out of the flipping assembly 52. ​​The limiting mechanism 6 includes a placement hole 61, a limiting hole 62, and a sliding groove 63. The placement hole 61 and the limiting hole 62 are both opened above the limiting mechanism 6. The sliding groove 63 is opened on one side of the limiting mechanism 6. The extended end of the sliding rod 51 moves back and forth in the sliding groove 63. The size of the sliding rod 51 can be just matched with the size of the sliding groove 63 to improve the stability of the reciprocating movement of the sliding rod 51 and prevent the sliding rod 51 from shifting longitudinally. At the same time, a baffle 7 is connected to the end of the sliding rod 51. The size of the baffle 7 is larger than the sliding groove 63 to effectively prevent the sliding rod 51 from falling out. The placement hole 61 and the limiting hole 62 can be used to insert limiting bolts 8 to open and close the device in different working states.

[0022] like Figure 4 As shown, under normal operating conditions, the limiting bolt 8 is placed in the placement hole 61 of the limiting mechanism 6. When the hydraulic cylinder extends and lifts the tilting mechanism 5 or the housing, the tilting mechanism 5 rotates counterclockwise around the tilting shaft 4. The sliding rod 51 in the tilting mechanism 5 extends out of the tilting assembly 52 and can reciprocate within the sliding groove 63 of the limiting mechanism 6. During the lifting and tilting process of the tilting mechanism 5, the sliding rod 51 tends to move closer to the limiting shaft 9. The sliding rod 51 moves to the left within the sliding groove 63, thus causing the limiting mechanism 6 to rotate counterclockwise around the limiting shaft 9. When the hydraulic cylinder retracts and lowers the tilting mechanism 5 or the housing, the tilting mechanism 5 rotates clockwise around the tilting shaft 4. During this process, the sliding rod 51 tends to move away from the limiting shaft 9. The sliding rod 51 moves to the right within the sliding groove 63, thus causing the limiting mechanism 6 to rotate clockwise around the limiting shaft 9. Under normal operating conditions, the placement hole 61 where the limiting bolt 8 is fixed is always outside the working stroke of the sliding rod 51, therefore the limiting mechanism 6 does not work under normal operating conditions.

[0023] like Figure 5As shown, in the fault repair state, the hydraulic cylinder extends and lifts the tilting mechanism 5 or the housing, causing the tilting mechanism 5 to rotate counterclockwise around the tilting shaft 4. The sliding rod 51 in the tilting mechanism 5 extends out of the tilting assembly 52. ​​During the lifting and tilting process, the sliding rod 51 tends to move closer to the limiting shaft 9. The sliding rod 51 moves to the left within the sliding groove 63, thus causing the limiting mechanism 6 to rotate counterclockwise around the limiting shaft 9. When the hydraulic cylinder extends to its maximum stroke, the tilting mechanism 5 tilts to the predetermined position, and the limiting bolt 8 is inserted from the placement hole 61 of the limiting mechanism 6 into the limiting hole 62, preventing the reciprocating movement of the sliding rod 51 and locking the mechanism, thus achieving the limiting function. After the fault is repaired, the limiting bolt 8 is reinserted into the placement hole 61, and normal operation is restored.

[0024] Secondly, the aforementioned limiting bolt 8 can be replaced by a limiting pin or other structures that can effectively limit the reciprocating motion of the sliding rod 51.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
