[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail in conjunction with the accompanying drawings and specific implementation methods. The technical solution in the embodiment of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiment of the present invention.

As used in the specification of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0036] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0037] See also Figure 1-7 As shown, this embodiment discloses a lifting tool vehicle, which is used to load materials and can move the materials to a target area.

[0038] The lifting tool vehicle of this embodiment includes: an outer frame 1 and a placement frame 2; the outer frame 1 and the placement frame 2 are open at the top, and the placement frame 2 is slidably connected to the outer frame 1 along the vertical direction of the outer frame 1; a storage space is provided in the placement frame 2, and the storage space is used to store materials.

[0039] In this embodiment, the accommodation space is used to accommodate beam structures used in the refrigerator, such as beam structures such as horizontal beams, longitudinal beams, flip beams, and middle beams, and the beam structures are vertically inserted into the placement rack 2 to move with the outer frame 1. It can be understood that in other embodiments, the accommodation space can be used to accommodate rod-shaped structures, plate-shaped structures, strip-shaped structures, columnar structures, or beam structures of other devices.

[0040] The lifting tooling vehicle of the present embodiment improves the convenience of material taking and placing operations by designing the outer frame 1 and the top openings of the placement rack 2, and the placement rack 2 slides vertically on the outer frame 1, so that the placement rack 2 can be moved up to extend out of the outer frame 1, reducing the obstruction of the placement rack 2 by the outer frame 1, facilitating manual and robot taking and placing operations, and helping to cooperate with automated equipment to realize fully automated loading and unloading operations, thereby greatly improving the production efficiency of refrigerators.

[0041] Specifically, the height of the outer frame 1 is greater than the height of the placement rack 2. The height of the outer frame 1 exceeds the placement rack 2, and can completely accommodate the placement rack 2, and can have enough space to accommodate materials, so that the materials can be placed vertically in the placement rack 2, which helps to prevent the materials from being disturbed or damaged by the external environment during transportation or storage. At the same time, vertical placement of materials can greatly reduce the space occupied by a single material compared to horizontal placement, thereby increasing the capacity of the placement rack 2, so that the lifting tool vehicle can load and move a large amount of materials at one time, which can reduce the frequency of material transfer, help reduce the time used for refrigerator production, and thus improve the production efficiency of refrigerators; the outer frame 1 can also provide a barrier layer for the material to prevent most areas of the material from protruding from the outer frame 1 and accidentally dumping during the movement of the outer frame 1, ensuring the quality and integrity of the material, and protecting the safety of surrounding personnel and equipment.

[0042] Specifically, the outer frame 1 is provided with a guide 21, and the placement rack 2 is provided with a slide 11; or, the outer frame 1 is provided with a slide 11, and the placement rack 2 is provided with a guide 21; wherein the slide 11 is slidably connected to the guide 21, so that the placement rack 2 is slidably connected to the outer frame 1. The guide 21 is used to guide the placement rack 2 to move in the vertical direction, and the slide 11 cooperates with the guide 21 to achieve smooth movement of the placement rack 2, reduce the movement resistance of the placement rack 2, reduce the labor intensity of the staff or the burden of the automation equipment, and help improve the efficiency of taking and placing materials.

[0043] Specifically, the guide member 21 is arranged vertically, and the sliding member 11 slides along the length direction of the guide member 21. The guide member 21 is arranged vertically, and the length direction of the guide member 21 is the vertical direction, which ensures the accuracy of the moving track of the placement rack 2, so that the placement rack 2 can only move in the vertical direction, and avoids the placement rack 2 from shaking horizontally during the movement of the outer frame 1 and affecting the placement stability of the material.

[0044] Specifically, the guide member 21 is provided with a guide rail 211, and the sliding member 11 is provided with a slide groove 111; the guide rail 211 is passed through the slide groove 111. The guide rail 211 cooperates with the slide groove 111, the structure is simple, and the space occupied is small, so that the lifting type tooling vehicle has a compact structure and is easy to maintain and repair. By cooperating with the guide rail 211 and the slide groove 111, not only the sliding connection between the placement rack 2 and the outer frame 1 is realized, but also the detachable connection between the placement rack 2 and the outer frame 1 can be realized. The detachable placement rack 2 facilitates the maintenance, inspection and replacement of the placement rack 2. Once the placement rack 2 is worn or malfunctions, the placement rack 2 can be quickly and easily removed from the outer frame 1 for necessary repairs or replacements without disassembling the entire lifting tool vehicle, which greatly reduces the maintenance cost and difficulty and extends the service life of the lifting tool vehicle. At the same time, it also helps to improve the degree of automation of the loading operation. The placement rack 2 can be disassembled for loading materials, avoiding the obstruction of the placement rack 2 by the outer frame 1, providing the robot with more sufficient activity space to load materials at high speed.

[0045] In specific implementation, when the placement rack 2 rises to the point where the guide rail 211 leaves the chute 111, or the chute 111 leaves the guide rail 211, the placement rack 2 is separated from the outer frame 1, so that the automated equipment drives the placement rack 2 to move to the material loading location, such as the side of the loading belt line, so that the automated fixture can absorb the material and directly place it in the placement rack 2. After the placement rack 2 is filled, the automated equipment clamps the placement rack 2 and moves it to the outer frame 1 to complete the loading of the lifting tooling vehicle, so that the material follows the outer frame 1 to move to the designated workstation for assembly. It is understandable that in specific implementation, the placement rack 2 can also be lifted and maintained to a designated height by automated equipment, and the guide member 21 and the sliding member 11 are not separated from each other. After the automated fixture has filled the placement rack 2 with materials in sequence, the automated equipment pushes the placement rack 2 to move the placement rack 2 downward until the placement rack 2 falls steadily on the outer frame 1 to complete the loading of the lifting tooling vehicle.

[0046] In this embodiment, the guide member 21 is arranged on the outer side wall of the placement rack 2, and the sliding member 11 is fixedly arranged on the inner side wall of the outer frame 1. When the placement rack 2 is moved up or down, the guide rail 211 of the guide member 21 moves relative to the sliding member 11 driven by the placement rack 2. The guide member 21 is arranged vertically and has a small volume. It is arranged on the placement rack 2, which is conducive to saving the space occupied by the placement rack 2.

[0047] It can be understood that in other embodiments, the installation positions of the guide member 21 and the sliding member 11 can be adjusted according to actual needs, such as setting the guide member 21 on the inner wall of the outer frame 1, and the sliding member 11 on the outer wall of the placement rack 2; or setting the guide member 21 at the inner corner of the outer frame 1, and the sliding member 11 at the outer corner of the placement rack 2; or setting the guide member 21 at the outer corner of the placement rack 2, and the sliding member 11 at the inner corner of the outer frame 1.

[0048] Specifically, the guide member 21 and the placement rack 2 are integrated structures. The guide member 21 and the placement rack 2 are integrated structures, so that the connection between the guide member 21 and the placement rack 2 is more secure, and the guide member 21 is not easy to loosen or fall off, thereby improving the stability and safety of the lifting tool vehicle; the integrated structure reduces the assembly steps required in the production of the lifting tool vehicle, thereby reducing the production difficulty of the lifting tool vehicle and improving the production efficiency of the lifting tool vehicle.

[0049] Specifically, there is at least one guide member 21 and at least one slide member 11. Multiple guide members 21 and slide members 11 can provide more uniform support and guidance, ensure that the placement rack 2 remains stable during movement, and reduce the possibility of shaking and deviation; multiple guide members 21 and slide members 11 can disperse the load between the placement rack 2 and the outer frame 1, and reduce the pressure on a single guide member 21 and slide member 11, which helps to extend the service life of the guide member 21 and slide member 11 and reduce damage and failure caused by overload.

[0050] It is understandable that the number of guide members 21 does not need to correspond to the number of sliding members 11. For example, in an optional embodiment, a sliding member 11 is provided on an inner wall of the outer frame 1, and two guide members 21 are provided on the two symmetrical outer walls of the placement rack 2, respectively. Any guide member 21 can cooperate with the sliding member 11, so that after the placement rack 2 adjusts its direction, it can still be slidably connected with the sliding member 11 on the outer frame 1, thereby improving the placement flexibility and adaptability of the placement rack 2, avoiding the need to re-shift and move downward when the placement rack 2 is assembled in the wrong direction, and improving the practicality and use experience of the lifting tooling vehicle.

[0051] Specifically, the placement rack 2 includes: a bottom support 22 and two side frames 23; the two side frames 23 are symmetrically arranged, and the two ends of the bottom support 22 are respectively connected to the bottom of the two side frames 23; a storage space is formed between the bottom support 22 and the side frames 23. The symmetrically arranged side frames 23 ensure the balance of the placement rack 2, so that the placement rack 2 remains stable when loaded with materials; the bottom support 22 is used to support the materials to prevent the materials from falling from the placement rack 2 and the outer frame 1 to the outside of the outer frame 1. The cooperation between the bottom support 22 and the side frames 23 constitutes a stable placement rack 2 structure that can effectively support and accommodate materials.

[0052] It is understandable that, in a specific implementation, the beam structures can be placed at intervals on the front and back sides, so that a plurality of beam structures are filled between the two side frames 23 , so that the materials are placed stably and the shaking of the materials during the movement of the outer frame 1 is avoided.

[0053] Specifically, the guide member 21 is arranged on the outer side wall of the side frame 23. The outer side wall provides a vertical installation space for the guide member 21, and the outer side wall is connected to the bottom bracket 22, which can provide a stable support force for the guide member 21, and at the same time avoids the guide member 21 being arranged on one side of the accommodation space to affect the placement of materials.

[0054] Specifically, the lifting tool vehicle of this embodiment further includes: a plurality of buffers 3; the two ends of the buffers 3 are respectively connected to the two side frames 23; and the plurality of buffers 3 are linearly distributed along the length direction of the side frames 23. The two ends of the buffers 3 are connected to the side frames 23, so that the side frames 23 and the buffers 3 form a stable frame structure, thereby improving the structural stability and reliability of the placement rack 2. The arrangement of the buffers 3 divides the accommodation space into multiple columns of accommodation subspaces, which facilitates the separation of each column of materials and provides a buffering effect for adjacent columns of materials to prevent the materials from colliding or abrading with each other.

[0055] Specifically, the buffer 3 is a separator. The separator has a buffering effect and can effectively share the lateral pressure of the material, thereby providing support for the material to prevent the material from tilting and colliding with each other during movement. Compared with traditional foam, the use of separators to separate and buffer materials can prevent foam aging and impurities from easily adhering to the material, which can cause the material to turn black.

[0056] It is understandable that, in other embodiments, the buffer component 3 may also be made of hard material, and buffer material such as rubber, flannel, cotton, foam, etc. may be wrapped around the surface of the hard material to improve the buffering effect of the buffer component 3.

[0057] In an optional embodiment, such as the present embodiment, a plurality of buffer members 3 are linearly distributed along the length direction and the height direction of the side frame 23. Figure 6 As shown, the buffer 3 is arranged perpendicular to the side frame 23, and a plurality of buffers 3 are distributed in a rectangular array on the inner wall of the side frame 23, so that both sides of each accommodating subspace are buffered by multiple buffers 3, which not only disperses the load of a single buffer 3 and reduces the pressure borne by a single buffer 3, but also helps to extend the service life of the buffer 3 and the placement rack 2, and reduce the impact of the buffer 3 on adjacent materials due to insufficient material supporting force caused by overloading.

[0058] Specifically, the lifting tooling vehicle of this embodiment further includes: a plurality of partitions (not shown); the partitions and the buffer 3 are arranged perpendicular to each other, and the plurality of partitions are linearly distributed on the buffer 3 along the length direction of the buffer 3. The partitions are arranged perpendicular to the buffer 3, and can divide the containing subspace into a plurality of smaller spaces, so as to separate a plurality of materials on the same column from each other, thereby improving the orderliness of material placement, and at the same time, avoiding mutual interference, friction and collision between adjacent materials, ensuring the integrity and surface smoothness of the materials, and thus helping to improve the performance and quality of the refrigerator.

[0059] Specifically, the two ends of the separator are respectively connected to any two buffers 3 on the same horizontal plane. The separator can connect two adjacent buffers 3, or two buffers 3 outside one or more buffers 3, that is, the separator can be arranged across multiple buffers 3, which reduces the number of separators, thereby reducing the assembly links of the separators, and further improving the production efficiency of the lifting tool vehicle.

[0060] In this embodiment, the two ends of the partition are respectively connected to the two buffers 3 that are farthest apart on the same horizontal plane. The partition is arranged across each buffer 3, which can separate each accommodating subspace, and at the same time, the divided spaces are arranged neatly and orderly, and the number of partitions and assembly links are reduced, simplifying the production process of the lifting tooling vehicle.

[0061] In this embodiment, the separator is flannel, which is wound around two buffer members 3. Flannel has a soft texture and good buffering performance. When used as a separator, it can effectively absorb and disperse the impact force between materials, reducing the friction and collision of materials during transportation or storage; and the flannel has a low cost and a certain wear resistance, which can resist the friction and wear of materials during transportation to a certain extent. When the flannel is worn, it is also very easy to replace, which reduces the difficulty of maintaining the placement rack 2; the flannel has flexible variability, and the installation method and installation position of the separator and the buffer member 3 can be adjusted according to actual needs, so that the placement rack 2 can be flexibly adjusted according to the size of the material, which improves the versatility and applicability of the placement rack 2 and the lifting tooling vehicle.

[0062] It can be understood that in other embodiments, the separator can be a rod-shaped or plate-shaped member with elasticity and flexibility; or the separator can also be a rod-shaped or plate-shaped member with a certain hardness, and a buffering material such as rubber, velvet, cotton, foam, etc. is wrapped around the surface of the rod-shaped or plate-shaped member to improve the buffering effect of the separator.

[0063] Specifically, the buffer 3 is provided with a plurality of grooves 31, which are arranged at intervals along the length direction of the buffer 3; the separator is arranged in the groove 31. The arrangement of the groove 31 provides installation space for the separator, improves the space utilization of the placement rack 2, and also facilitates the engagement of the separator with the groove 31, thereby improving the connection stability between the separator and the buffer 3. In addition, the plurality of grooves 31 arranged at intervals can evenly distribute the separator, thereby improving the orderliness of material storage.

[0064] Specifically, flannel is wound around the surface of the placement rack 2. The flannel on the placement rack 2 can prevent the partition, the buffer 3, and the side frame 23 from wearing the surface of the material.

[0065] Specifically, flannel is wound on the surface of the outer frame 1. The flannel on the outer frame 1 can prevent the outer frame 1 from abrading the surface of the material during the process of taking or storing the material.

[0066] Specifically, a handle 4 is provided on the outer wall of the outer frame 1. The handle 4 provides a holding space, so that the staff can grasp the handle 4 and push the outer frame 1, thereby improving the user experience of the lifting type work vehicle and further improving the efficiency of material transfer.

[0067] Specifically, a pulley assembly 5 is provided at the bottom of the outer frame 1. The provision of the pulley assembly 5 enables the lifting tool vehicle to move easily, speeds up the moving speed of the materials, improves the moving efficiency of the materials, and further improves the production efficiency of the refrigerator.

[0068] Specifically, the pulley assembly 5 includes: four universal wheels 51; the four universal wheels 51 are rotatably connected to the bottom of the outer frame 1. The universal wheels 51 can rotate freely 360 degrees, which makes the pulley assembly 5 extremely flexible when moving and adjusting its position. Whether in a small space or in a complex environment, the universal wheels 51 can easily cope with it, so that the lifting tooling vehicle can easily change direction and achieve efficient movement of materials; and the high flexibility of the universal wheels 51 makes it unnecessary for the staff to spend too much effort when pushing the outer frame 1 or turning, reducing the physical burden of the operator; in addition, the universal wheels 51 can maintain a stable balance in the vertical direction, so that the pulley assembly 5 can still maintain stable performance when the placement rack 2 is fully loaded or moving at high speed, reducing the collision between materials.

[0069] Specifically, the two universal wheels 51 near one end of the handle 4 are universal wheels with brakes 51. The universal wheels with brakes 51 can be quickly locked when needed to prevent the lifting tool vehicle from sliding due to external forces, which can effectively avoid the safety risks caused by the lifting tool vehicle losing control or accidentally moving. The two universal wheels 51 near one end of the handle 4 are designed with brakes, so that the staff can easily control the movement and stop of the outer frame 1 when needed.

[0070] The present embodiment provides a lifting type work vehicle, which improves the convenience of material picking and placing operations by designing an outer frame and an opening on the top of a placement rack. The placement rack slides vertically on the outer frame, so that the placement rack can be moved up to extend out of the outer frame, reducing the obstruction of the placement rack by the outer frame, making it easier for manual and robot pick-up and placement operations, and helping to cooperate with automated equipment to achieve fully automated loading and unloading operations, thereby greatly improving the production efficiency of refrigerators.

[0071] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
