Description

Technical Field

[0001] This utility model relates to the field of heavy equipment relocation technology, specifically to a device for step-by-step relocation on a track, and particularly to a track relocation device for gradually raising equipment. Background Technology

[0002] In large-scale engineering projects, such as shipbuilding and marine engineering facility construction, it is often necessary to lift and move heavy equipment or components over long distances. Existing technologies for moving such equipment each have their own focus, but all have certain limitations.

[0003] For example, existing technology CN115676688B discloses a step-by-step lifting device, the core of which is to achieve vertical lifting of the equipment through a lifting mechanism and stacked pads, and is equipped with a material preparation platform and a feeding trolley for transporting the pads. Although this technical solution solves the problem of automated lifting, its function is mainly focused on vertical lifting operations, and it does not provide an effective solution for long-distance, high-precision horizontal movement of the equipment after lifting. Its feeding trolley is only used to transport pads and cannot drive the entire lifting equipment and its load to move accurately in both directions along the track with a large stroke. Therefore, if the entire workstation needs to be moved, the equipment often needs to rely on external traction or other moving devices, resulting in low system integration, complex operation procedures, and low overall efficiency.

[0004] For example, the existing technology CN202611759U discloses a self-moving conveyor tail-end pushing device, which utilizes a pushing cylinder and a pushing track with a one-way brake block to achieve self-movement, providing a horizontal pushing approach. However, the reaction mechanism of this device, namely the one-way brake block, has a limited function, typically only enabling unidirectional movement in one direction or requiring complex operations to change direction, lacking flexible and efficient bidirectional self-movement capabilities. When applied to scenarios requiring repeated position adjustments or precise bidirectional displacement, such as adjusting the posture of equipment by gradually raising it, it becomes inadequate. Furthermore, the interaction between its reaction mechanism and the track is relatively simple, potentially leading to deficiencies in movement smoothness and positioning accuracy, making it difficult to meet the stringent requirements for movement accuracy and stability in the high-end equipment manufacturing field.

[0005] In summary, there is a significant technological gap in the existing technology: the lack of a dedicated device that can be efficiently integrated with tiered elevation equipment and provide it with stable, reliable, and precisely controllable horizontal pushing force. Existing lifting equipment lacks an effective built-in horizontal movement scheme, while traditional pushing devices cannot meet the requirements for flexible bidirectional movement and high-precision positioning. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of existing lifting equipment in lacking integrated horizontal driving capability, as well as the inflexible bidirectional movement and insufficient positioning accuracy of traditional pushing devices. It provides a track pushing device for step-by-step raising equipment that can be efficiently integrated with the step-by-step raising equipment to achieve stable and accurate bidirectional step-by-step pushing.

[0007] To solve the above problems, this utility model provides a track-pushing device for a gradually raised equipment, comprising: The track base assembly extends along the track direction and is provided with multiple reaction structures arranged along the length direction; A sliding base component is slidably mounted on the track base assembly for supporting and guiding the load-bearing platform; The support platform, installed on the sliding base component, is used to support the gradually elevated equipment and transported items; A drive power mechanism is mounted on the track base assembly and is drivenly connected to the sliding base component to provide pushing force; A reaction force interaction mechanism is connected to the drive power mechanism and configured to selectively engage with the reaction force structure of the track base assembly; The driving power mechanism interacts with the reaction force structure through the reaction force interaction mechanism. During the driving stroke, it uses the reaction force to push the sliding base component to move along the track direction, and during the return stroke, it causes the reaction force interaction mechanism to disengage from the current reaction force structure and reset, so as to realize the step-by-step movement of the sliding base component.

[0008] Preferably, the track base assembly includes a base slide plate, reaction plates symmetrically arranged on the base slide plate, and a base connecting plate and connecting pin for track connection. The reaction plates are provided with an array of reaction windows, forming the reaction structure. The track base assembly provides a stable and reliable stepping foundation, and the array of reaction windows provides continuous and precise application points for the reaction interaction mechanism, ensuring the accuracy and consistency of the stepping displacement. The symmetrically arranged reaction plates, in conjunction with the base connecting plate and connecting pin, not only enable modular expansion of the device, easily adapting to different stroke requirements, but more importantly, provide a symmetrical mechanical environment for bidirectional movement, fundamentally solving the technical problem of the difficulty in flexibly changing direction in traditional unidirectional pushing devices.

[0009] Preferably, the sliding base component includes symmetrically arranged guide plates and a friction pair disposed at the bottom. The friction pair contacts the base slide plate of the track base assembly to reduce sliding resistance. This significantly improves the smoothness and accuracy of movement. The symmetrical guide plates effectively limit the lateral offset of the sliding base, ensuring its linear movement along the track direction. The large-area friction pair at the bottom and the base slide plate form a low-friction coefficient kinematic pair, greatly reducing sliding resistance and avoiding crawling, making startup and operation under heavy loads smoother, laying a solid foundation for achieving high-precision positioning.

[0010] Preferably, the drive power mechanism includes a pusher seat and a pusher cylinder. The piston rod of the pusher cylinder is connected to the sliding base component via a connecting flange and a flange pin. The pusher seat is fixedly connected to the pusher cylinder. This achieves rigidity and reliability in power transmission. The pusher cylinder, as the core power source, forms a stable hinged connection with the sliding base via the connecting flange and flange pin, ensuring effective transmission of thrust and accommodating minor installation errors. The pusher seat, as a stable mounting base, supports the cylinder and connects to the reaction mechanism, forming a compact and efficient power unit.

[0011] Preferably, the reaction force interaction mechanism includes opposing reaction blocks. A pin passes through pin holes at both ends of the reaction block to connect it to the pusher seat. The reaction block has a working surface and a tilting ramp on its side for engaging or disengaging from the reaction structure. The opposing reaction blocks, connected by pins, form an ingenious one-way clutch mechanism. The working surface rigidly engages with the reaction window during the push stroke, providing a large reaction force; while the tilting ramp contacts the window during the return stroke, forcing the reaction block to rotate and lift, thus achieving interference-free reset. This design achieves a fully automatic engagement-push-disengagement-reset cycle without external control, resulting in extremely high automation and reliability.

[0012] Preferably, the reaction block is configured to provide a reaction force by contacting the reaction structure with its working surface when the piston rod of the pushing cylinder extends, and to return to its original position by contacting the reaction structure with its flipped inclined surface and rotating around the pin of the reaction block when the piston rod retracts, so as to enter the next working cycle.

[0013] Preferably, the sliding base components are connected as a whole by a sliding base connecting rod to move synchronously, greatly enhancing the integrity and stability of the system. The sliding base connecting rod rigidly connects the two parallel sliding bases together, ensuring their absolute synchronization during movement and preventing jamming, uneven loading, or equipment tilting caused by asynchrony. This is crucial for supporting precision or heavy equipment and ensures the safety and smoothness of the moving process.

[0014] Preferably, the reaction force interaction mechanism is symmetrically arranged, and the sliding base component can move bidirectionally along the track direction by switching working modes.

[0015] Compared with the prior art, the present invention achieves the following beneficial technical effects: This invention achieves efficient integration and unified drive of lifting and translation functions. It is designed specifically for equipment that is raised in stages. The lifting platform directly supports the raised equipment and the horizontal movement function is built into the system. This eliminates the drawback of existing lifting equipment that requires external devices for horizontal movement. It enables the lifted equipment to move self-driven over long distances on the track, which significantly improves work efficiency and system integration.

[0016] This invention provides a flexible, efficient, and reliable bidirectional stepping movement capability. Through the ingenious interaction between a symmetrically arranged reaction force interaction mechanism and an array of reaction force structures on the track base, and the docking of the reaction force blocks and reaction force windows, stable stepping motion driven by a single power source is achieved. By simply switching the reaction force blocks during operation, forward and backward movement can be seamlessly realized, completely solving the problems of difficult bidirectional movement and complex operation in existing technologies. It is particularly suitable for high-precision working conditions that require repeated adjustments to posture.

[0017] This invention ensures high stability and high positioning accuracy during movement. On one hand, the sliding base effectively distributes the load and reduces frictional resistance by contacting the sliding plate of the track base through a large-area friction pair on its bottom, ensuring smooth operation. On the other hand, the precise fit between the working surface of the reaction block and the reaction window provides rigid reaction support, avoiding sliding and crawling phenomena, making the displacement of each step accurately controllable, thus meeting the stringent requirements of high-end equipment manufacturing for movement accuracy.

[0018] This invention boasts excellent scalability and on-site adaptability. The track base assembly adopts a modular design, allowing for longitudinal extension via base connecting plates and connecting pins to easily adapt to different travel requirements. The sliding bases are connected as a whole by sliding connecting rods, enhancing structural stability and load-bearing capacity. This design facilitates transportation, rapid on-site assembly and adjustment, and enhances practicality.

[0019] This invention has a reliable working principle and a high degree of automation. The entire pushing process is completed through the automatic engagement, disengagement, and reset cycle of the hydraulic cylinder extension and retraction and the reaction mechanism. No manual intervention is required to adjust the reaction mechanism, which realizes efficient automated stepping pushing, reduces the labor intensity and skill requirements of operators, and improves the safety of operation.

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. This embodiment is implemented based on the technical solution of this utility model, but the scope of protection of this utility model is not limited to the following embodiments.

[0029] like Figures 1 to 6 As shown, the track pushing device of the step-by-step elevation equipment of this utility model mainly includes a track base assembly 1, a sliding base component 2, a drive power mechanism 3, a sliding seat connecting rod 4, and a bearing platform 5.

[0030] During installation, the track base assembly 1 is first assembled according to the required travel distance. Then, the assembled sliding base component 2 and the support platform 5 are hoisted onto the track. Finally, the drive power mechanism 3 is placed at the end of the track and hinged to the sliding base component 2 via a pin.

[0031] The track base assembly 1 is preferably made of high-strength steel by welding or casting, forming the fixed foundation of the device. A base slide plate 11 is installed at its bottom, providing a smooth sliding surface; symmetrically arranged above are reaction plates 12, with multiple reaction windows 121 arrayed along the length direction on the reaction plates 12. These windows serve as key reaction fulcrums during the pushing process. The ends of the track base assembly 1 are provided with base connecting plates 13, which can be used to easily splice multiple track units longitudinally via connecting pins 14, achieving modular extension of the track. To adapt to different travel requirements, multiple track base assemblies 1 are placed parallel to each other along the track direction according to the required travel distance. By aligning the base connecting plates 13 of adjacent units and inserting connecting pins 14, the track base assembly 1 can be spliced ​​and extended in the length direction to form a complete track that meets the needs of long-distance movement.

[0032] The sliding base component 2 is slidably mounted on the track base assembly 1, serving as the supporting foundation for the moving part. Symmetrically arranged guide plates 21 are installed on both sides of the sliding base component 2, engaging with the sides of the track base assembly 1 to ensure no deviation during movement. An array of friction pairs 22 is installed at the bottom of the sliding base component 2. These friction pairs 22 directly contact the base slide plate 11 of the track base, forming a low-friction kinematic pair to reduce sliding resistance and ensure smooth operation. When installing the sliding base component 2, two sets of sliding base components 2 are placed on two parallel track base assemblies 1. The friction pairs 22 at the bottom of the sliding base component 2 directly contact the base slide plate 11 of the track base 1, forming a low-friction kinematic pair. The guide plates 21 on both sides of the sliding base 2 engage with the sides of the track base 1, providing guidance and preventing deviation. Subsequently, the two sliding bases 2 are connected into a stable overall frame using a sliding base connecting rod 4.

[0033] The drive power mechanism 3, mounted on the track base assembly 1, is the core unit providing the pushing force. It mainly includes a pushing seat 31 and a pushing cylinder 32. The cylinder body of the pushing cylinder 32 is fixedly connected to the pushing seat 31, and its piston rod front end is hinged to the sliding base component 2 via a connecting flange 33 and a flange pin 34. On the left and right sides of the pushing seat 31, opposing reaction blocks 35 are hinged to each other via reaction block pins 36. These reaction blocks 35 are key components for achieving the stepping function; their sides are precisely machined with a working surface 352 and a tilting slope 353, and a pin hole 351 in the middle for the reaction block pin 36 to pass through.

[0034] When arranging the drive power mechanism 3 and the reaction force interaction mechanism, the drive power mechanism 3 is placed at the end of the track base 1. This mechanism consists of a pusher seat 31, a pusher cylinder 32, a connecting flange 33, a flange pin 34, a reaction block 35, and a reaction block pin 36. The cylinder body of the pusher cylinder 32 is fixedly connected to the pusher seat 31. The connecting flange 33 at the front end of the piston rod of the pusher cylinder 32 is hinged to the sliding base 2 via the flange pin 34. The reaction block 35 is connected to the pusher seat 31 via two opposing sets and the reaction block pin 36. The reaction block 35 can rotate freely within a certain angle around its pin. The reaction block 35 is machined with a working surface 352 and a tilting inclined surface 353.

[0035] The sliding base connecting rod 4 is used to rigidly connect two sets of parallel sliding base components 2 into an integral frame, ensuring their absolute synchronization during movement and preventing jamming or uneven loading caused by asynchrony.

[0036] The supporting platform 5 is fixedly installed above the sliding base component 2, which is connected as a whole, and is used to directly support the step-up device 6 and the transported items 7 on it. During installation, the supporting platform 5 is hoisted and fixedly installed above the two sliding bases 2, which are connected as a whole. After that, the step-up device 6 and the items 7 to be transported can be placed on the supporting platform 5.

[0037] To facilitate understanding of the above technical solutions of this utility model, the following detailed description of the above technical solutions of this utility model is provided through a specific working process.

[0038] Combination Figure 7 The "working state of the reaction block when moving to the right" shown below has the following step-by-step working cycle: When a rightward movement is required, the hydraulic system drives the piston rod of the push cylinder 32 to extend. Since the piston rod is connected to the sliding base 2 via the connecting flange 33, its initial intention is to push the sliding base 2 to the right. However, at this time, the sliding base 2 and the load above it are enormous, resulting in extremely high static friction. According to the principle of action and reaction, the reaction force of the extended cylinder will attempt to push the cylinder body and the fixed push seat 31 to the left. This tendency causes the right-side reaction block 35, under the action of gravity or a slight external force, to quickly achieve rigid contact and engagement with the lower edge of a reaction window 121 on the right-side reaction plate 12 of the track. Once engaged, the right-side reaction block 35 is locked, providing a solid fulcrum for the push seat 31. At this point, the enormous thrust of the extended piston rod of the push cylinder 32 is entirely converted through this fulcrum into the power to push the sliding base 2 and its above-mounted support platform 5, the step-by-step elevation device 6, and the transport object 7 to the right by one cylinder stroke. During this process, the left-side reaction block 35 will be lifted and pass through because its flipped inclined surface 353 contacts the reaction window 121, and will be in a non-working follow-up state.

[0039] When the piston rod is fully extended and one stroke is completed, the hydraulic system switches the oil circuit, causing the piston rod of the push cylinder 32 to retract. The pulling force of the retracting piston rod attempts to pull the sliding base 2 back to the left, but is again blocked by the large load. The reaction force then attempts to pull the cylinder and push base 31 to the right. At this time, the flipping ramp 353 of the right-side reaction block 35 will meet the contact edge of the next reaction window 121. Under the action of the ramp, the reaction block 35 is subjected to an upward component force, causing it to rotate upward around the reaction block pin 36, thereby disengaging from the reaction window 121.

[0040] After disengagement, the right-side reaction block 35 no longer provides constraint, allowing the pusher seat 31 to move to the right and reset along with the cylinder until it returns to the starting position of the next working cycle. During this process, the left-side reaction block 35 will fall, but its working surface will not engage with the window, thus providing no effective reaction force.

[0041] When the piston rod is fully retracted and the pusher seat 31 has been reset, the right reaction block 35 automatically falls and resets under the action of gravity, preparing for the next push stroke.

[0042] By repeating the above cycle of "extend-push" and "retract-reset", the platform and its equipment can be moved to the right in a stable and precise step-by-step manner.

[0043] When it needs to move to the left, its working principle is completely symmetrical to that of moving to the right. At this time, the hydraulic system changes the oil supply direction, so that the working surface 352 of the left reaction block 35 engages with the reaction window 121 of the left reaction plate 12 during the forward stroke to provide reaction force, and becomes the working state; while the right reaction block 35 flips and disengages during the return stroke, and becomes the non-working state.

[0044] By simply switching the extension and retraction sequence of the push cylinder 32 through the hydraulic system, the active reaction block can be automatically switched, thereby achieving seamless switching between forward and backward movement of the device, making operation extremely simple and flexible.
