Description

Technical Field

[0001] The invention relates to the field of logistics transportation equipment, and in particular to a multi-point fixing device for hoisting and installing vertical and horizontal transportation equipment. Background Art

[0002] In modern logistics and transportation, during the lifting process of vertical and horizontal transport equipment, chains, lifting belts and other fixing methods are usually used to connect the transported items to the lifting equipment or transport platform. These devices have a certain degree of flexibility and can adapt to items of different sizes and shapes. They are especially widely used when transporting rectangular or large items. However, this traditional fixing method still has many limitations when facing complex transportation scenarios.

[0003] In actual use, existing fixing devices often require manual adjustment of the position and length of the fixing points according to the shape and weight of the transported items. Although chains and lifting belts are flexible, they lack a systematic fixing structure, resulting in complex operation and low efficiency. In addition, for cylindrical or irregular objects, chains and lifting belts can only provide basic unidirectional tension support and cannot effectively limit lateral rolling or sliding. In dynamic transportation environments (such as road vibrations or ship shaking), these fixing methods are difficult to ensure the stability of the items, increasing safety hazards during transportation. At the same time, during loading and unloading operations, cylindrical objects are often difficult to quickly position and fix due to their rolling characteristics, further reducing operational efficiency.

[0004] Although chains and lifting belts are flexible, the integration and multi-directional support design of the fixing system in existing devices has not been perfected, and reliable limit functions and multi-point support cannot be provided. When transporting objects with complex shapes or uneven weight distribution, the fixing points are scattered and unevenly stressed, which can easily cause the objects to tilt, slide, or even fall off. In addition, the use and storage of these decentralized fixing methods often require additional space, which limits the convenience and management efficiency of the equipment.

[0005] Based on this, the present invention proposes a multi-point fixing device for lifting and installing vertical and horizontal transportation equipment. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a multi-point fixing device for lifting and installing vertical and horizontal transport equipment, which solves the problems of lack of flexibility, limiting function and multi-scenario adaptability in the existing transport equipment fixing methods.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multi-point fixing device for lifting and installing vertical and horizontal transportation equipment, including two tripods and a chain assembly, the two tripods are connected by two hinges, the inner walls of the two tripods are installed with connecting parts one and two, which are used to connect the lifting equipment with the multi-point fixing device, the two tripods are penetrated by through holes at both ends near one side, two adjacent perforations are provided with connecting rings, the outer wall of the connecting ring is provided with a hook one, and the outer walls of the two tripods are installed with multiple installation components, which are used to fix the items to be transported or connect them with other multi-point fixing devices through lifting belts, chains or other connecting parts.

[0008] Preferably, the connecting member 1 includes two mounting member groups 1, and the two mounting member groups 1 are respectively installed on both sides of the inner wall of the tripod, and a lifting ring 1 is installed in each of the two mounting member groups 1, which is used for connecting the lifting device to the lifting ring 1 through a hook when the tripod is unfolded to 180°, thereby lifting the device in the unfolded state and the items to be transported.

[0009] Preferably, the second connecting member includes two second mounting member groups, and the two second mounting member groups are respectively installed on both sides of a middle frame of the tripod. Two lifting rings are installed in the two second mounting member groups, which are used for connecting the two lifting rings on the bottom tripod through the lifting hook when the two tripods are folded, so that the folded multi-point fixing device can be lifted.

[0010] Preferably, the mounting assembly includes a first mounting component, a second mounting component and a third mounting component, which are respectively used to completely fix and place the items through chains or lifting belts according to the actual situation of transporting the items;

[0011] The first installation component comprises a second fixing member, which is installed on the outer wall of the tripod. A third hook is installed inside the second fixing member. The second fixing member and two through holes are respectively located on three vertices of the tripod.

[0012] Preferably, the second mounting component comprises two fixing members 1, the two fixing members 1 are respectively mounted on two symmetrical sides of the tripod, and each of the fixing members 1 is provided with a hook 2.

[0013] Preferably, the third mounting component comprises two fixing members three, both of which are mounted on the bottom edge of the tripod, and both of which are provided with hooks four.

[0014] Preferably, the chain assembly comprises a long chain and a short chain, the two ends of the long chain are respectively connected to the hook two on the multi-point fixing devices on the upper and lower sides, and the two ends of the short chain are respectively connected to the hook four on the multi-point fixing devices on the upper and lower sides.

[0015] Preferably, the two tripods are combined into a rhombus shape through two hinges.

[0016] The present invention provides a multi-point fixing device for hoisting and installing vertical and horizontal transport equipment. It has the following beneficial effects:

[0017] 1. The present invention uses the hinged design of two tripods and hinges to enable the device to flexibly switch between the unfolded and folded states. When it is necessary to transport larger or complex-shaped items, the tripod can be unfolded to 180° to form a stable plane structure and provide a sufficient support platform; when transporting a small number or smaller items, the tripod can be folded to form a diamond structure, which significantly reduces the occupied space and improves transportation efficiency. In addition, the design of connector 1 and connector 2 enables the device to automatically adapt to the lifting requirements in different states, avoiding additional adjustments, thereby meeting the transportation requirements in different scenarios.

[0018] 2. Through the reasonable layout of the first mounting component, the second mounting component, and the third mounting component, the present invention can realize multi-point distributed fixation according to the actual shape and weight of the transported items. For example, the first mounting component is suitable for vertex support of large items, and the second mounting component provides middle support through symmetrical distribution. The third mounting component, the second mounting component, and the cooperation of long and short chains together form a fixing device suitable for transporting cylindrical items. In particular, the combination of the short chain and the triangular area forms a natural limiting structure, which can effectively prevent the lateral rolling or displacement of cylindrical items during transportation. Compared with plane support, it avoids problems such as tilting and sliding due to uneven force.

[0019] 3. The present invention fully utilizes geometric stability through the geometric design of the triangular area and the diamond structure, improves the overall seismic resistance and load-bearing performance of the device, and when transporting cylindrical objects, the triangular area avoids sliding or tilting due to concentrated force through evenly distributed force points, while reducing dependence on additional fixing tools. The diamond structure lowers the center of gravity in the folded state, ensuring the balance of the device during transportation, preventing tilting or shaking caused by center of gravity shift, and further improving the adaptability of the device in complex transportation environments.

[0020] 4. The present invention realizes the modular combination function of the multi-point fixing device through the combined connection of long chains and short chains. The upper and lower devices provide longitudinal support through the long chain, and the short chain limits the lateral displacement, thereby ensuring the vertical and lateral stability of multi-layer objects. It is particularly suitable for the stacking and transportation needs of cylindrical or extra-long objects. The modular design not only expands the application range of the device, but also significantly improves the bearing capacity and vibration resistance of the device. At the same time, the modular combination simplifies the loading and unloading process, facilitates the rapid construction of a stable transportation system, and is suitable for a variety of complex scenarios.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a multi-point fixing device for lifting and installing vertical and horizontal transportation equipment, including two tripods 1 and a chain assembly. The two tripods 1 are connected by two hinges 2. The inner walls of the two tripods 1 are installed with connecting parts 1 and 2, which are used to connect the lifting equipment with the multi-point fixing device. The two tripods 1 are penetrated by through holes 7 at both ends near one side, and connecting rings 8 are sleeved in two adjacent through holes 7. The outer wall of the connecting ring 8 is sleeved with a hook 9. The outer walls of the two tripods 1 are installed with multiple installation components, which are used to fix the objects to be transported or connect them with other multi-point fixing devices through lifting belts, chains or other connecting parts.

[0031] Specifically, the multi-point fixing device of the present invention includes two tripods 1 and a chain assembly. The two tripods 1 are hingedly connected by two hinges 2, which ensures that the device can be flexibly switched between the unfolded and folded states, thereby adapting to different transportation needs. In practical applications, when it is necessary to transport larger or complex-shaped items, the two tripods 1 are unfolded to 180° through the hinges 2 to form a planar structure, thereby providing a stable support platform; when transporting a small number or smaller items, the tripods 1 can be folded to reduce the space occupied by the device and improve transportation efficiency. The design of the hinge 2 not only ensures the structural strength of the device, but also facilitates the device to quickly switch between different states, thereby improving operating efficiency.

[0032] Connectors 1 and 2 are installed on the inner walls of the two tripods 1 for connecting the lifting equipment to the multi-point fixing device. Connectors 1 and 2 include mounting component group 1 3 and mounting component group 2 5, respectively. The lifting ring 1 4 in mounting component group 1 3 is at the top position when the tripod 1 is unfolded, which is convenient for connection with the lifting equipment, so that the whole device is evenly stressed when lifted, thereby improving the stability of the device during transportation. The lifting ring 2 6 in mounting component group 2 5 is at the top position when the tripod 1 is in the folded state, and is specially designed for transportation in the folded state, so that the device can also be used with the lifting equipment in the folded state. The advantage of this connector design is that it automatically adapts to the lifting requirements according to the different states of the device, without the need for additional adjustments, and is convenient and efficient to use.

[0033] The connection ring 8 is mainly used for folding and unfolding switching between the two tripods 1, and plays a role of flexible connection and support.

[0034] The design of various installation components, combined with chains and lifting belts, can flexibly adapt to the transportation needs of items of different shapes, weights and sizes, effectively improving the versatility of the device.

[0035] Please see attached Figure 1 -Attached Figure 3 The connecting member 1 includes two mounting member groups 3, which are respectively mounted on both sides of the inner wall of the tripod 1. A lifting ring 4 is installed in each of the two mounting member groups 3. When the tripod 1 is unfolded to 180°, the lifting equipment is connected to the lifting ring 4 through the hook, so as to lift the device in the unfolded state and the items to be transported.

[0036] Specifically, when the tripod 1 is unfolded to 180 degrees through the hinge 2, the lifting ring 4 is at the top position and docked with the hook of the lifting equipment to form a stable lifting point.

[0037] During use, the unfolded tripod 1 ensures that the device is evenly stressed during lifting through the reasonable distribution of the lifting ring 4, avoiding deformation or tilting of the device due to excessive stress at a single point. The connection between the lifting ring 4 and the hook not only provides a strong load-bearing capacity, but also enables the lifting equipment to smoothly lift the device and the fixed items to be transported as a whole, ensuring the safety and stability of the transportation process.

[0038] Please see attached Figure 1 -Attached Figure 3 The connecting member 2 includes two mounting member groups 2 5, and the two mounting member groups 2 5 are respectively installed on both sides of the middle frame of a tripod 1. A lifting ring 2 6 is installed in each of the two mounting member groups 2 5. When the two tripods 1 are folded, the lifting equipment is connected to the two lifting rings 2 6 on the bottom tripod 1 through a hook, so that the folded multi-point fixing device is lifted.

[0039] Specifically, when the two tripods 1 are folded by the hinges 2, the second lifting ring 6 is located on the top of the bottom tripod 1 in the folded state, and becomes the main connection point with the lifting equipment.

[0040] In the folded state, the lifting device is connected to the lifting ring 2 6 through the hook, and the reasonable layout of the two lifting rings 2 6 is used to form a uniform lifting support for the folded device. At this time, since the tripod 1 has been folded, the device occupies less space, and the position design of the lifting ring 2 6 ensures that the center of gravity is stable during the lifting process, avoiding shaking or tilting of the device due to the displacement of the center of gravity.

[0041] Please see attached Figure 3 -Attached Figure 7 The installation assembly includes a first installation component, a second installation component and a third installation component, which are respectively used to fix and place the items by using chains or lifting belts according to the actual conditions of transporting the items;

[0042] The first installation component includes a second fixing member 12 , which is installed on the outer wall of the tripod 1 , a third hook 13 is installed inside the second fixing member 12 , and the second fixing member 12 and the two through holes 7 are respectively located at three vertices of the tripod 1 .

[0043] The second installation component includes two fixing members 10 , which are respectively installed on two symmetrical sides of the tripod 1 , and each fixing member 10 is installed with a hook 2 11 .

[0044] The third installation component includes two fixing members three 15, and the two fixing members three 15 are both installed on the bottom edge of the tripod 1, and the two fixing members three 15 are both installed with hooks four 16.

[0045] Specifically, the mounting assembly includes a first mounting component, a second mounting component and a third mounting component, which are used to flexibly cooperate with chains or lifting belts according to the actual shape, weight and fixing requirements of the transported items to achieve reliable fixing and stable support of the items. Each mounting component is distributed at different positions of the tripod 1, and has a clear functional division and coordination effect.

[0046] Working principle of the first installation part:

[0047] The hook 3 13 utilizes the structural strength of the top point of the tripod 1 as a support point to provide a stable fixed position for fixing the items to be transported.

[0048] In actual use, the lifting belt or chain can be connected to different positions of the object through the hook 3 13, so as to realize a multi-point distribution fixing method, ensuring that the object is evenly stressed and stable during transportation, which is especially suitable for larger rectangular or irregular shaped objects.

[0049] Working principle of the second mounting part:

[0050] The hooks 11 are symmetrically distributed to provide additional fixing points in the middle of the object, so that the object can be fixed more evenly. Especially when transporting long objects, the symmetrically distributed hooks 11 can effectively prevent the object from tilting due to gravity offset or uneven force.

[0051] The hook 2 11 can also be used as a connection point when used in modular combination, and is connected to other devices through a long chain 14 or a short chain 17 to form a stable multi-layer fixing system.

[0052] Working principle of the third installation part:

[0053] The hook 416 is mainly used to fix cylindrical or special-shaped objects, and the objects are stably placed at the bottom of the device by using the supporting force provided by the bottom edge of the tripod 1.

[0054] In the modular combination, the hook 4 16 can also be connected to other devices through a short chain 17 to further enhance the lateral stability.

[0055] How overall coordination works:

[0056] Through the reasonable distribution of the three installation parts, the device can flexibly select the fixing method according to the different shapes of the transported items, such as rectangle, irregular shape, cylinder, etc.

[0057] The first mounting component provides vertex support, which is suitable for edge fixation of large objects; the second mounting component achieves middle support through symmetrical distribution to balance the overall force; the third mounting component focuses on bottom support, which is especially suitable for the stable transportation of cylindrical objects.

[0058] The installation components can be flexibly connected by lifting belts or chains, so that items can be fixed at multiple points to ensure safety and stability during transportation.

[0059] During use, according to actual transportation conditions, the bagged items can be directly lifted for transportation by hook three 13, hook one 9, hook two 11 and hook four 16 in the unfolded state or folded state, depending on the actual conditions.

[0060] Please see attached Figure 3 The chain assembly includes a long chain 14 and a short chain 17. The two ends of the long chain 14 are respectively connected to the hooks 11 on the upper and lower multi-point fixing devices, and the two ends of the short chain 17 are respectively connected to the hooks 16 on the upper and lower multi-point fixing devices.

[0061] Specifically, the upper and lower fixing devices are connected by the short chain 17 and the long chain 14. The combined design of the long chain 14 and the short chain 17 enables the stacked tubes to be firmly fixed between the upper and lower multi-point fixing devices.

[0062] Long chain 14: maintains vertical force transmission, supports the upper and lower devices, and enables the stacked rollers to be evenly supported upward.

[0063] Short chain 17: prevents the cylindrical objects from rolling in the lateral direction, and further restricts the lateral movement of the cylinder by connecting the lateral fixing points of the bottom and top devices.

[0064] By combining the long chain 14 and the short chain 17 with the upper and lower devices, the bottom device is folded at a certain angle, while the top device is unfolded. In this way, a triangular area for stacking cylindrical objects is formed between the chain and the bottom device. The bottom edge of the triangular area cooperates with the short chain 17 to form a natural limiting structure, which effectively prevents the roller tube from rolling horizontally due to vibration or center of gravity shift during transportation. Compared with flat stacking, which requires additional fixing measures such as triangular baffles or anti-slip pads, the triangular area itself can provide anti-rolling function through geometric structure, reducing the dependence on additional support tools.

[0065] At the same time, the geometric structure of the triangular area is naturally highly stable. Compared with a plane, its corners and support points are evenly distributed, which can better limit the rolling tendency of roller-type items.

[0066] When the roller tube is stacked in the triangular area, the contact points of the items are more dispersed and the force is evenly distributed, avoiding the tilting or sliding caused by uneven force when stacking on a single plane.

[0067] This design optimizes the transportation safety and stability of the roller tube body, and at the same time, through the longitudinal and lateral constraints of the chain assembly, a modular device combination is realized, which is suitable for complex transportation environments. In order to ensure that the items will not fall off during hoisting and transportation, binding tools are required to further fix the transported items after they are placed.

[0068] Please see attached Figure 1 , two tripods 1 are combined through two hinges 2 to form a rhombus.

[0069] Specifically, two tripods 1 are connected and combined by two hinges 2 to form a diamond structure. The design of the hinge 2 enables the two tripods 1 to rotate freely within a certain range, thereby flexibly realizing the switching of the diamond-shaped unfolded state or folded state. The formation of the diamond structure utilizes the geometric stability of the triangle, further enhancing the overall strength and anti-deformation ability of the device.

[0070] When the two tripods 1 are unfolded to form a rhombus through the hinges 2, the geometric center of the device is located at the intersection of the diagonal lines of the rhombus. At this time, the center of gravity of the device is lower, ensuring the balance and stability of the force during the hoisting process. The two diagonal lines of the rhombus represent the main force paths of the device in the vertical direction and the horizontal direction, respectively, so that during the force process of the device, the force can be evenly distributed to each vertex of the tripod 1, avoiding structural damage or deformation that may be caused by concentrated force at a single point.

[0071] Mechanical stability: The diamond structure combined with the characteristics of the triangle can effectively disperse the weight of the items and reduce the risk of vibration or deviation during transportation.

[0072] Easy to modularize: The diamond structure provides clear upper, lower and lateral connection points such as hook 2 11 and hook 4 16, which is convenient for connecting multiple devices using long chains 14 and short chains 17 to form a stable combined system.

[0073] Strong adaptability: When transporting cylindrical or other regular / irregular objects, the diamond structure can adjust the expansion range by changing the angle of hinge 2 to adapt to objects of different sizes and shapes.

[0074] Working principle: According to the type and shape of the items to be transported, choose the appropriate device state to unfold or fold and the fixing method. Prepare the hook of the lifting equipment such as a crane or electric hoist to ensure that it can be connected to the device's lifting ring 1 4 or lifting ring 2 6.

[0075] Case 1: Transportation of rectangular or irregular shaped items

[0076] The two tripods 1 are unfolded to 180 degrees through the hinges 2 to form a plane structure. After the tripods 1 are unfolded, the lifting ring 4 in the mounting assembly 3 is at the top position, which is convenient for use with lifting equipment. According to the size and shape of the object, the first mounting component and the second mounting component, as well as the connecting rings 8 on both sides, are selected to fix the object between the lifting hook 3 13, the lifting hook 2 11 or the lifting hook 1 9 through the lifting belt. Figure 7 As shown, the device of the present invention uses two lifting belts to cooperate with the hook three 13 and the hook one 9 to fix the object. The specific use needs to be adjusted according to the actual situation. Use the hook of the lifting device to connect to the lifting ring one 4 to ensure that the lifting device can smoothly lift the unfolded device and the object as a whole. The lifting device gradually lifts the device and lifts it and the object to the target height. After completing the vertical or horizontal movement, the object is smoothly lowered to the target position and the lifting belt is released.

[0077] Case 2: Transportation of cylindrical objects

[0078] Combine multiple multi-point fixing devices in a modular manner, and use a long chain 14 and a short chain 17 to connect the upper and lower devices:

[0079] A long chain 14 is used to connect the hooks 11 of the upper and lower devices to form a support.

[0080] A short chain 17 is used to connect the hooks 16 of the upper and lower side devices to form a stable structure.

[0081] Place cylindrical objects on the tripod 1 of the bottom multi-point fixing device, refer to the attached Figure 4 As shown, secure the items with chains, lifting straps or other fixings to ensure stability during transportation.

[0082] The hook of the lifting device is connected to the lifting ring 14 of the top device to lift the modular assembly as a whole. The lifting device gradually lifts the assembly to transport the cylindrical object as a whole to the target position.

[0083] Case 3: Folding device transportation is suitable for transporting a small amount of items

[0084] Fold the two tripods 1 through the hinges 2 to reduce the floor space. In the folded state, the lifting ring 2 6 of the mounting assembly 2 5 is at the top position. Use a chain or lifting belt to connect the tray base through the hook 1 9, the hook 2 11 and the hook 3 13. Refer to the attached Figure 6As shown, a pallet is used as a support platform, a small amount of items are stacked on the pallet seat, and then fixed with a fixing belt: the items can also be directly fixed with a chain or a lifting belt. The hook of the lifting device is connected to the lifting ring 26 of the folding device to lift the entire structure. The lifting device gradually lifts the device and transports it and the items as a whole to the target location. After the transportation is completed, the items are removed from the pallet or the fixing piece to complete the loading and unloading operation.

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
