Technical Field
[0001] This utility model relates to the field of loading platform connection technology, specifically a loading platform connection device that is easy to maintain. Background Technology
[0002] With the booming development of the logistics industry, the volume of cargo transportation and turnover efficiency continue to rise. As a key transitional connection device between different loading platforms, the daily usage frequency of loading platform connecting devices has increased significantly. The high frequency of operation not only puts forward higher requirements for the structural stability and load-bearing capacity of the device, but also makes the maintenance needs of the equipment more urgent. Regular component inspection, replacement of worn parts, lubrication and maintenance have become necessary links to ensure its safe operation.
[0003] However, traditional loading platform coupling devices have significant limitations in their structural design: the core components are mostly connected by rigid methods such as bolts and nuts, without a dedicated quick-release structure. This design means that during maintenance, operators must use tools such as wrenches and screwdrivers to disassemble each component one by one, which is not only cumbersome and time-consuming, but also seriously affects maintenance efficiency. More importantly, frequent tool disassembly causes continuous wear on bolts, screw holes, and other connecting components, easily leading to problems such as stripped threads and increased clearance, which can cause the connection to loosen or even fail, posing a great safety hazard to loading operations.
[0004] For example, the cargo loading and docking device described in application number CN202420531443.2 achieves a composite motion of lifting and horizontal movement of cargo through the cooperation of a lifting drive device (hydraulic cylinder) and a lateral drive device, which solves the problem that traditional lifting platforms cannot be horizontally adjusted, but it does not have a quick disassembly structure to improve maintenance convenience.
[0005] Based on this, this solution proposes a loading platform connection device that is easy to maintain in order to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a loading platform erection device that is easy to maintain, so as to solve the problem mentioned in the background art that the existing loading platform erection devices on the market have obvious limitations in structural design and do not have a quick disassembly structure to improve the convenience of maintenance.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a loading platform connection device that is easy to maintain, comprising a support frame, a limiting cover plate, a support plate, a first quick-release frame, and a connecting plate;
[0008] A quick-connect structure is provided below the support frame. The quick-connect structure includes a hydraulic rod, a limiting frame, a handle, a first insertion rod, a second insertion rod, and a spring. The handle is located inside the first insertion rod, the spring is fitted onto the side of the first insertion rod, and the second insertion rod is installed on the side of the limiting frame.
[0009] As a preferred technical solution of this utility model, the bottom surface of the support frame is a grid-shaped structure, and the side of the support frame is a right-angled L-shaped structure, and a limiting cover plate is hinged on the top of the support frame;
[0010] The above technical solution features a grid-shaped bottom surface for the support frame, which enhances load-bearing stability by evenly distributing stress points while ensuring overall structural strength. This also reduces the device's weight, facilitating handling and maintenance. The sides are right-angled L-shaped, improving compatibility with components such as the limiting cover and support plate. The right-angled sides create stable support and limit, preventing loosening of connections due to stress and extending the device's lifespan. Furthermore, the hinged limiting cover at the top of the support frame allows for easy access to internal components during maintenance and provides lateral restraint for goods during use, preventing slippage and improving operational safety.
[0011] As a preferred technical solution of this utility model, a circular through hole is opened on the left side of the limiting cover plate, and a bearing plate is rotatably connected between the limiting cover plate and the bearing frame. The side of the bearing plate is a beveled structure, and a grid-like anti-slip texture is provided on the surface of the bearing plate.
[0012] Using the above technical solution, the circular through hole on the left side of the limiting cover provides a precise insertion and positioning point for the first quick-release frame. With the quick-release structure, it can be quickly fixed or separated from the carrier frame, shortening the assembly and disassembly time. The carrier plate, which is rotatably connected between the limiting cover and the carrier frame, can be flexibly adjusted in tilt angle with the hydraulic rod to adapt to overlapping scenarios of different heights or slopes. The sloping structure on the side of the carrier plate facilitates a smooth transition of goods, reducing bumps during overlapping. The grid-like anti-slip texture on the surface increases the friction between the goods and the carrier plate, effectively preventing the goods from sliding and improving safety.
[0013] As a preferred technical solution of this utility model, the side through hole of the limiting cover plate and the support frame are inserted and engaged by the first quick release bracket, the support frame and one end of the hydraulic rod are rotatably connected by the second quick release bracket, the other end of the hydraulic rod is rotatably connected to the support plate by the third quick release bracket, and the hydraulic rod is driven by an external hydraulic component.
[0014] Using the above technical solution, the first quick-release bracket is inserted into the side through hole of the limiting cover plate and engages with the support frame; the second quick-release bracket connects the support frame to one end of the hydraulic rod; and the third quick-release bracket connects the other end of the hydraulic rod to the support plate. All three are quick-release structures, allowing for rapid disassembly and assembly of components without tools, significantly improving maintenance efficiency. The hydraulic rod is driven by an external hydraulic component, avoiding the structural complexity caused by integrating the hydraulic system inside the device. This facilitates individual maintenance or replacement of the hydraulic component, reducing the probability of failure. Furthermore, the rotational connection between the hydraulic rod and related components ensures smooth movement when adjusting the angle of the support plate, reducing component wear and extending service life.
[0015] As a preferred technical solution of this utility model, the first quick-release bracket, the second quick-release bracket, and the third quick-release bracket all adopt the same structure;
[0016] By adopting the above technical solution, the first quick-release frame, the second quick-release frame, and the third quick-release frame all adopt the same structure, which reduces the mold cost and parts management difficulty during production and manufacturing, and eliminates the need to distinguish between different models of quick-release frames. At the same time, maintenance personnel only need to be familiar with the operation of one quick-release structure to complete the disassembly and assembly of all quick-release parts, simplifying the maintenance process and improving the ease of operation.
[0017] As a preferred technical solution of this utility model, the first quick-release frame has a first insert rod and a second insert rod slidably connected to both sides of the limiting frame, the second insert rod is fixedly connected to the first insert rod with a handle, the handle is slidably connected to the limiting frame, and the second insert rod and the first insert rod are fitted with springs on their sides.
[0018] Using the above technical solution, the first and second insertion rods are slidably connected to the two sides of the limiting frame of the first quick-release frame, and the two are fixedly connected by a handle. With the help of the spring fitted on the side, a linkage structure is formed. When the handle is pressed, the insertion rod retracts to unlock; when the handle is released, the spring returns to its original position and pushes the insertion rod out to lock. The operation is simple and effortless, and the insertion rod is evenly stressed in the locked state, resulting in high connection stability. The spring can also absorb some of the impact force when the device is subjected to vibration or impact, reducing the rigid collision between the insertion rod and the limiting frame and extending the service life of the quick-release structure.
[0019] As a preferred embodiment of this utility model, the side of the bearing plate is hinged to a connecting plate, and the thickness of the connecting plate is half that of the bearing plate;
[0020] Using the above technical solution, the connecting plate hinged to the side of the bearing plate can be unfolded or folded according to the overlap length requirements. When unfolded, it can extend the effective overlap length of the bearing plate, adapting to platform transitions over longer distances. When folded, it fits snugly against the side of the bearing plate, without occupying extra space, making it convenient for device storage and transportation. Moreover, the thickness of the connecting plate is half that of the bearing plate, ensuring that it will not protrude from the surface of the bearing plate after folding, avoiding obstruction of cargo overlap, while also reducing its own weight and reducing the load on the rotating connection parts.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. The grid-shaped structure on the bottom of the support frame and the right-angled L-shaped structure on the sides reduce its weight while ensuring stable load-bearing capacity. The hinged limiting cover is easy to open for maintenance and also limits the goods. The rotating connection design of the support plate allows for flexible angle adjustment, while the beveled structure and anti-slip texture improve the smoothness and safety of goods overlapping.
[0023] 2. The quick-release structure is the core of the device's ease of maintenance. The first, second, and third quick-release frames have the same structure, allowing for quick assembly and disassembly of the limit cover, hydraulic rod, support frame, and support plate without tools, which greatly improves maintenance efficiency. The external hydraulic components also reduce the maintenance difficulty of the hydraulic system.
[0024] 3. The limit bracket, handle, first insertion rod, second insertion rod and spring in the quick-release structure work together in harmony. Pressing the handle will retract and pop out the insertion rod. The operation is simple. The spring not only provides the reset power, but also buffers the impact and extends the service life of the quick-release structure.
[0025] 4. The design of the connecting plate enhances the adaptability of the device. The hinged structure allows it to be extended to extend the overlap length or folded for storage as needed. Its thickness is half that of the bearing plate, which avoids affecting the overlap of goods and reduces the load on the connection parts. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figure 1 - Figure 7 The present invention provides a convenient and easy-to-maintain loading platform connection device.
[0036] Example 1
[0037] For details, please refer to the following: Figure 1 - Figure 5 It includes a support frame 1, a limiting cover plate 2, a support plate 3, a first quick-release frame 4, a second quick-release frame 5, a third quick-release frame 6, a hydraulic rod 7, a limiting frame 8, a handle 9, a first insertion rod 10, a second insertion rod 11, and a spring 12;
[0038] The bottom of the support frame 1 adopts a grid-shaped structure design, with right-angled L-shaped structures on the sides. The top of the support frame 1 is hinged to the limiting cover plate 2. The grid-shaped structure on the bottom of the support frame 1 significantly improves the load-bearing stability while ensuring the overall structural strength through the even distribution of multi-directional force nodes. At the same time, the hollow design reduces the weight of the device and optimizes the convenience of handling and maintenance. The right-angled L-shaped structure on the sides enhances the connection and compatibility with components such as the limiting cover plate 2 and the support plate 3 through the rigid support of the right-angled sides, forming a stable limiting constraint. This effectively avoids the risk of loosening caused by force displacement at the connection points and extends the fatigue service life of the device. The hinged structure between the support frame 1 and the limiting cover plate 2 provides a convenient path for exposing internal components during maintenance operations and can form a reliable lateral limiting for the load during operation, reducing the risk of the load slipping and improving operational safety.
[0039] A circular through hole is provided on the left side of the limiting cover plate 2, and a bearing plate 3 is rotatably connected between the limiting cover plate 2 and the bearing frame 1. The side of the bearing plate 3 is designed with a sloping structure, and its surface is processed with a grid-like anti-slip texture. The circular through hole on the left side of the limiting cover plate 2 provides a high-precision insertion and removal positioning reference for the first quick-release frame 4. Combined with the quick-release structure, it realizes the quick engagement and disengagement of the limiting cover plate 2 and the bearing frame 1, which greatly shortens the disassembly and assembly time. The rotatable connection design between the bearing plate 3 and the limiting cover plate 2 and the bearing frame 1, combined with the driving action of the hydraulic rod 7, can realize multi-angle tilt adjustment to meet the needs of overlapping scenarios with different height differences or slopes. The sloping structure on the side of the bearing plate 3 reduces the impact load during cargo overlapping through a smooth transition design, reducing collision damage. The grid-like anti-slip texture on the surface increases the friction coefficient of the contact interface, effectively suppressing the sliding tendency of the cargo during dynamic overlapping, and improving operational safety.
[0040] The side through-hole of the limiting cover plate 2 and the support frame 1 are engaged by the insertion and locking of the first quick-release bracket 4. The support frame 1 and one end of the hydraulic rod 7 are rotatably connected by the second quick-release bracket 5, and the other end of the hydraulic rod 7 is rotatably connected to the support plate 3 by the third quick-release bracket 6. The hydraulic rod 7 is driven by an external hydraulic component. The quick-release connection system composed of the first quick-release bracket 4, the second quick-release bracket 5, and the third quick-release bracket 6 realizes tool-free quick disassembly and assembly of the limiting cover plate 2 and the support frame 1, the support frame 1 and the hydraulic rod 7, and the hydraulic rod 7 and the support plate 3, which significantly improves the efficiency of maintenance operations. The external drive design of the hydraulic rod 7 avoids the complex layout of the integrated hydraulic system and the main structure of the device, facilitates the individual inspection and replacement of hydraulic components, and reduces the difficulty of troubleshooting system faults. The rotatable connection method between the hydraulic rod 7 and related components ensures the smooth movement of the support plate 3 when adjusting its angle by eliminating rigid constraints, reduces contact wear between components, and extends the service life of the device.
[0041] The first quick-release frame 4, the second quick-release frame 5, and the third quick-release frame 6 adopt a unified structural design. The unified structure of the first quick-release frame 4, the second quick-release frame 5, and the third quick-release frame 6 reduces the mold development cost and the complexity of parts inventory management, and realizes standardized production. At the same time, the unified structural design allows maintenance personnel to complete the disassembly and assembly of all quick-release parts by mastering only a single operating procedure, which simplifies the maintenance process, reduces the operation error rate, and improves the convenience of operation.
[0042] The limiting frame 8 of the first quick-release bracket 4 is slidably connected to the first insertion rod 10 and the second insertion rod 11 on both sides. The second insertion rod 11 is fixedly connected to the inner side of the first insertion rod 10 with a handle 9. The handle 9 is slidably engaged with the limiting frame 8, and springs 12 are fitted on the sides of both the second insertion rod 11 and the first insertion rod 10. The sliding connection structure between the limiting frame 8 and the first insertion rod 10 and the second insertion rod 11, together with the linkage design of the handle 9, forms an efficient insertion and removal drive mechanism. Pressing the handle 9 can simultaneously realize the retraction and unlocking of the two insertion rods. After releasing, the spring 12 drives the insertion rods to pop out and lock through the return force. The operation is effortless and the response is fast. The symmetrical arrangement of the two insertion rods ensures the force balance in the locked state and improves the connection reliability. The elastic buffering effect of the spring 12 can absorb the impact energy when the device is vibrated, reduce the rigid collision between the insertion rod and the limiting frame 8, delay component fatigue, and extend the service life of the quick-release structure.
[0043] Example 2
[0044] For details, please refer to the following: Figure 6 and Figure 7 The difference between this embodiment and embodiment one is that a connecting plate 13 is hinged to the side of the bearing plate 3, and the thickness of the connecting plate 13 is half the thickness of the bearing plate 3.
[0045] The hinge structure of the bearing plate 3 and the connecting plate 13 enables the adjustment of the overlap length. When unfolded, it can extend the effective overlap distance to adapt to the transition requirements of long-span platforms. When folded, it fits the side of the bearing plate 3, reducing space occupation and optimizing storage and transportation convenience. The thickness of the connecting plate 13 is designed to be half that of the bearing plate 3, which not only avoids interference to the overlap of goods caused by the thickness protrusion after folding, but also reduces the load on the rotating connection parts through lightweight design, thereby improving the stability and durability of the hinge structure.
[0046] Working principle: When using a loading platform erection device that is easy to maintain, the assembly of each component is completed through the quick-release structure. The operator holds the handle 9 and presses it inward, which drives the first insertion rod 10 and the second insertion rod 11 to slide in the limiting frame 8, so that the spring 12 is compressed. The first quick-release frame 4 is aligned with the corresponding interface of the side through hole of the limiting cover plate 2 and the bearing frame 1. The operator releases the handle 9, the spring 12 returns to its original position and pushes the insertion rod to pop out, so as to realize the locking and fixing of the limiting cover plate 2 and the bearing frame 1. Similarly, the second quick-release frame 5 and the third quick-release frame 6 are respectively connected to the bearing frame 1 and the hydraulic rod 7, and the hydraulic rod 7 and the bearing plate 3.
[0047] Activate the external hydraulic components, extend or retract the hydraulic rod 7, and drive the bearing plate 3 to rotate around the connection point with the bearing frame 1. Adjust the tilt angle to adapt to different overlapping scenarios. The side slope of the bearing plate 3 facilitates the transition of goods, and the surface anti-slip texture prevents the goods from sliding.
[0048] During maintenance or transportation, press the handle 9 to release the quick-release frame and quickly disassemble the components. The connecting plate 13 on the side of the bearing plate 3 can be unfolded to extend the overlap length or folded for storage as needed, improving the adaptability of the device.
[0049] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0050] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
