[0030] 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.

[0033] 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.

[0034] See also Figure 1-10 As shown, this embodiment discloses a transfer device, which includes: a frame 1, a pulley assembly 2 and a plurality of material trays 3; the pulley assembly 2 is connected to the bottom of the frame 1; the plurality of material trays 3 are horizontally arranged and slidably connected to the frame 1 in sequence from top to bottom; the material trays 3 are provided with a plurality of placement holes 31, and the placement holes 31 are used to accommodate materials 9.

[0035] The transfer device of this embodiment is suitable for transferring columnar or tubular parts. Furthermore, in this embodiment, the transfer device is used to place and move the detection joint for vacuuming the refrigeration system, that is, the material 9 is the detection joint. In specific implementation, the corresponding material tray 3 is slid so that the placement hole 31 is exposed outside the frame 1; then the joint body of the detection joint is inserted into the placement hole 31, and the top of the material tray 3 contacts and supports the pipe sleeve of the detection joint, so that the detection joint can be stably placed on the material tray 3; then the material tray 3 is slid into the frame 1 to realize the recovery or placement of the detection joint.

[0036] The transfer device of this embodiment restricts the movement of the material 9 by setting the placement hole 31, so that the materials 9 are isolated from each other, avoiding mutual wear or collision between the materials 9, ensuring the quality and durability of the material 9, and further improving the sealing of the system; by setting the pulley assembly 2, the frame 1 can be conveniently moved between the transfer starting point and the destination, which greatly improves the efficiency of the material 9 transfer operation, and at the same time improves the movement stability of the material 9, effectively avoiding the risk of the material 9 escaping from the placement hole 31 and colliding with each other due to bumps or shaking, and further improves the reliability of the transfer operation; by stacking a plurality of material trays 3, the storage capacity of the transfer device is increased, so that more materials 9 can be moved at the same time, further improving the transfer efficiency of the material 9.

[0037] Specifically, the material tray 3 includes: a frame 32 and a support plate 33; the frame 32 is vertically penetrated with a through slot 321, the support plate 33 is connected to the top of the frame 32, and the support plate 33 is penetrated with a plurality of placement holes 31, and the placement holes 31 are arranged corresponding to the through slots 321. The through slots 321 are arranged corresponding to the placement holes 31, so that the bottom of the placement holes 31 is unobstructed, and it is easy for the protruding parts of the material 9, such as the pipe sleeve and other structures protruding from the main body, to abut against the top of the support plate 33, so that the bottom of the material 9 is suspended, reducing the contact area between the material tray 3 and the material 9, thereby reducing the friction of the material tray 3 on the material 9 during transportation and placement, and increasing the service life of the material 9.

[0038] Specifically, a plurality of placement holes 31 are distributed in a rectangular array on the support plate 33. The plurality of placement holes 31 are distributed in a rectangular array so that the materials 9 can be neatly arranged and orderly placed during the transportation process, thereby improving the management and access convenience of the materials 9.

[0039] Specifically, the support plate 33 is screwed to the frame 32. Furthermore, in this embodiment, the support plate 33 is screwed to the frame 32 by self-tapping screws. The screw connection improves the connection firmness and stability between the support plate 33 and the frame 32, and facilitates the disassembly, assembly and replacement of the support plate 33, thereby improving the practicality of the transfer device.

[0040] Specifically, the frame 32 includes: four support blocks 322 and four enclosure blocks 323; the four support blocks 322 are connected in sequence and connected head to tail, and a through slot 321 is formed between the four support blocks 322; the four enclosure blocks 323 are respectively connected to one end of the four support blocks 322 away from the through slot 321, and the support plate 33 is placed on the top of the four support blocks 322 and between the four enclosure blocks 323. The support blocks 322 are used to support the support plate 33, and the enclosure blocks 323 are used to limit the movement of the support plate 33 to prevent the support plate 33 from leaving the frame 32, thereby ensuring the placement stability of the material 9.

[0041] In this embodiment, the support block 322 and the enclosure block 323 correspond to each other and are perpendicular to each other. The support block 322 and the corresponding enclosure block 323 are formed by angle irons. The angle irons enhance the squareness and structural strength of the frame 32, making the material tray 3 more stable and reliable when carrying the material 9. The use of angle irons also improves the durability and deformation resistance of the frame 32. The angle irons have the advantages of low cost, easy processing and installation, etc., which helps to reduce the overall manufacturing cost of the transfer device.

[0042] In this embodiment, the support plate 33 is made of polyvinyl chloride material. Polyvinyl chloride (PVC, full name Polyvinyl Chloride) is a polymer material obtained by polymerization of vinyl chloride monomer, and is one of the five general-purpose plastics. Polyvinyl chloride material has good corrosion resistance, can resist the erosion of various chemical substances, and can resist the refrigerant and other chemical substances that the material 9 may contact in the refrigeration system; polyvinyl chloride material has certain strength and flexibility, can provide greater support for the support plate 33 and the material 9, while absorbing and dispersing part of the impact force, protecting the material 9 from collision damage during transportation; and the cost of polyvinyl chloride material is relatively low, which helps to reduce the overall manufacturing cost of the transfer device; polyvinyl chloride material also has certain environmental protection, can be recycled and reused, and reduce the impact on the environment; in addition, the support plate 33 made of polyvinyl chloride material has a certain degree of transparency, which is conducive to observing the integrity of the bottom of the material 9, and can promptly find the material 9 with a gap. Therefore, choosing polyvinyl chloride material as the manufacturing material of the support plate 33 not only improves the performance and durability of the transfer device, but also takes into account cost-effectiveness and environmental protection requirements.

[0043] It is understandable that in other embodiments, polyethylene, aluminum alloy, carbon fiber composite materials, etc. can be used to replace polyvinyl chloride materials according to actual needs.

[0044] In this embodiment, the frame 1 is a square frame 1, which is formed by connecting twelve square tubes. As a hollow square steel tube, the square tube has high strength and reduces the overall weight of the frame 1, making it easier to move the frame 1. The use of the square tube enables the frame 1 to withstand greater pressure and bending loads, ensuring the overall stability and safety of the transfer device; and the cost is low, which helps to reduce the manufacturing cost of the transfer device.

[0045] Specifically, a plurality of slide rail assemblies 4 are provided in the frame 1, and the material tray 3 is slidably connected to the slide rail assemblies 4; the slide rail assemblies 4 include two sliders 41; the two sliders 41 are symmetrically arranged on the inner wall of the frame 1, and the two ends of the material tray 3 are slidably connected to the top of the sliders 41. The plurality of slide rail assemblies 4 are arranged corresponding to the material tray 3 from top to bottom, so that each material tray 3 can be slidably connected to the frame 1 through the slide rail assemblies 4. The two sliders 41 are symmetrically arranged and respectively connected to two mutually symmetrical inner walls of the frame 1, so that the material tray 3 can slide steadily and smoothly in the frame 1.

[0046] Specifically, a limiter 42 is further provided above the slider 41, and the limiter 42 is connected to the inner wall of the frame 1, and there is a gap between the limiter 42 and the slider 41; the material tray 3 is slidably connected between the slider 41 and the limiter 42. The limiter 42 is used to limit the movement of the material tray 3 in the vertical direction, so as to prevent the material tray 3 from jumping due to bumps during the movement of the transfer device, and ensure the stability of the material tray 3 and the material 9 on the material tray 3.

[0047] Specifically, the slider 41 is arranged in an "L" shape, and is provided with a supporting portion 411 and a limiting portion 412; the supporting portion 411 is used to support the material tray 3, and the limiting portion 412 is vertically connected to the side of the supporting portion 411 away from the center of the frame 1. When the material tray 3 is placed in the frame 1, the bottom, side wall and top of the material tray 3 are respectively restricted by the supporting portion 411, the limiting portion 412 and the limiting member 42, which further improves the connection stability between the material tray 3 and the frame 1.

[0048] In this embodiment, the slider 41 is an angle iron. The angle iron enhances the squareness and structural strength of the slider 41, making the slider 41 more stable and reliable when carrying the material tray 3. The use of the angle iron also improves the durability and deformation resistance of the slider 41. The angle iron has the advantages of low cost, easy processing and installation, etc., which helps to reduce the overall manufacturing cost of the transfer device.

[0049] In this embodiment, the stopper 42 is a square tube. The square tube is a hollow square steel tube. While having high strength, it reduces the weight of the stopper 42, preventing the stopper 42 from sagging due to a large weight and jamming the material tray 3. The use of the square tube enables the stopper 42 to withstand a large pressure and bending load, ensuring the overall stability and safety of the slide rail assembly 4; and the cost is low, and it can also be recycled and reused, which is in line with the concept of sustainable development and can reduce the consumption and waste of natural resources.

[0050] Specifically, a blocking member 43 is provided at one end of the slider 41, and the blocking member 43 is provided between the slider 41 and the stopper 42. The blocking member 43 limits the sliding range of the material tray 3, and is provided at the end of the slider 41, thereby avoiding the risk of the material tray 3 falling off the slider 41.

[0051] In this embodiment, the blocking member 43 is an iron block, and the top and bottom of the blocking member 43 are welded to the limit member 42 and the slider 41 respectively. The two ends of the blocking member 43 are connected to the limit member 42 and the slider 41, which effectively avoids the formation of a gap between the limit member 42 and the blocking member 43 and causes the material tray 3 to get stuck, and to a certain extent ensures the smooth sliding of the material tray 3. The iron block has high wear resistance and can withstand the friction and wear generated by the material tray 3 during the sliding process. This helps to extend the service life of the blocking member 43 and reduce the frequency of replacement and maintenance; and the cost of the iron block is relatively low, with a higher cost performance, which can meet the blocking requirements of the material tray 3 and reduce the production cost of the transfer device.

[0052] Specifically, the transfer device also includes: a top plate 5a, a bottom plate 5b, a back plate (not marked in the figure), two side plates 6 and a door plate 7; the top plate 5a and the bottom plate 5b are respectively connected to the top and bottom surfaces of the frame 1, the door plate 7 is movably connected to one side of the frame 1, the back plate is connected to the side of the frame 1 away from the door plate 7, and the two side plates 6 are respectively connected to the two side surfaces of the frame 1 adjacent to the door plate 7; the sliding direction of the material tray 3 is parallel to the distribution direction of the door plate 7 and the back plate. The top plate 5a, the bottom plate 5b, the back plate and the two side plates 6 together constitute a semi-enclosed storage space, and the door plate 7 is used to cover or open the storage space. The door plate 7 covers the storage space, which helps to block external dust or other impurities for the material 9, so as to maintain the cleanliness of the material 9, and at the same time can prevent external objects from falling into the storage space and damaging the material 9; the door plate 7 opens the storage space, which is convenient for sliding the material tray 3 to take and put the material 9. In specific implementation, the door panel 7 is opened to pull out the material tray 3, and then the material 9 on the corresponding material tray 3 is taken and placed. After the material 9 is taken and placed, the material tray 3 is pushed until the material tray 3 abuts against the blocking member 43, and then the door panel 7 can be closed.

[0053] Specifically, at least two first hinges 71 are provided at one end of the door panel 7, and the frame 1 is provided with a second hinge 11 corresponding to the first hinge 71; the first hinge 71 is hinged to the second hinge 11. Through the first hinge 71 and the second hinge 11, the door panel 7 is flexibly rotated equivalent to the frame 1, thereby realizing the opening and closing of the accommodation space, which greatly improves the convenience of operating the door panel 7.

[0054] Specifically, the second hinge 11 is provided with a convex connection column 111, the first hinge 71 is provided with a concave connection groove 711 corresponding to the connection column 111, and the connection column 111 is passed through the connection groove 711. In specific implementation, the connection groove 711 is directly opposite to the connection column 111, and the first hinge 71 is pushed so that the connection column 111 is inserted into the connection groove 711, so that the installation of the door panel 7 is realized, the operation is simple and convenient, and it is conducive to improving the production efficiency of the transfer device.

[0055] In this embodiment, the first hinge 71 is arranged on the side wall of the door panel 7, and the first hinge 71 and the second hinge 11 are arranged in sequence in the vertical direction. The first hinge 71 and the second hinge 11 are vertically distributed, and there is no need to assemble fasteners. Under the weight of the door panel 7, the plugging of the connecting column 111 can ensure that the first hinge 71 does not separate from the second hinge 11 during the movement, which simplifies the structure of the door panel 7 and ensures the installation stability of the door panel 7.

[0056] It is understandable that in other embodiments, the first hinge 71 and the second hinge 11 can be respectively arranged at the top or bottom of the door panel 7 and the frame 1 according to actual needs, and a slide rail can be used to replace the first hinge 71 and the second hinge 11, that is, the door panel 7 is connected to the frame 1 by a sliding connection.

[0057] Specifically, the first hinge 71 and the second hinge 11 are respectively provided with a first connecting piece 712 and a second connecting piece 112, the door panel 7 is screwed to the first connecting piece 712, and the second connecting piece 112 is screwed to the frame 1. The first connecting piece 712 and the second connecting piece 112 provide installation space, increase the connection area between the door panel 7 and the first hinge 71, and the connection area between the second hinge 11 and the frame 1, and enhance the structural stability of the transfer device.

[0058] Specifically, the connection posts 111 of the two second hinges 11 face the same direction, and the connection slots 711 of the two first hinges 71 face the same direction. Furthermore, the connection posts 111 extend upward from the second hinges 11, and the connection slots 711 extend upward from the bottom of the first hinges 71. The two connection posts 111 and the two connection slots 711 face the same direction, which facilitates the detachable connection of the door panel 7 and facilitates the quick maintenance and replacement of the door panel 7.

[0059] Specifically, the end of the door panel 7 away from the first hinge 71 is provided with a first door lock catch 72, and the frame 1 is provided with a second door lock catch 12 corresponding to the first door lock catch 72. The first door lock catch 72 and the second door lock catch 12 can lock the door panel 7 through the door lock, which can ensure that the door panel 7 will not be opened due to the shaking, bumping or tilting of the transfer device during the transfer of the material 9, reducing the risk of the door panel 7 hitting the frame 1 and avoiding the shaking of the material tray 3 and the material 9.

[0060] Specifically, the transfer device further includes a handle 8 connected to a side surface of the frame 1. Furthermore, the handle 8 is disposed on a side surface of the frame 1 adjacent to the door panel 7, and the handle 8 provides a gripping space so that the staff can grasp the handle 8 to push the transfer device, thereby improving the user experience of the transfer device.

[0061] Specifically, the pulley assembly 2 includes: two moving wheels 21 and two fixed wheels 22. The fixed wheels 22 can only rotate in a fixed direction, providing stable support and movement for the transfer device on a specific route. In scenarios where a straight line is required, such as transferring materials 9 in a narrow channel, the high stability of the fixed wheels 22 is particularly important, which can prevent the transfer device from deviating from the predetermined route during movement, ensuring the safety and stability of the materials 9. The fixed wheels 22 have a relatively simple structure and are more concentrated in force, and can bear a large weight, which helps to disperse the weight and reduce the impact on the transfer device; the moving wheels 21 can rotate freely in all directions, making the transfer device more convenient when it needs to change direction or bypass obstacles, and helps to easily adjust the movement trajectory of the transfer device, improving the smoothness of the transfer device. The cooperation between the moving wheels 21 and the fixed wheels 22 not only ensures the balance between stability and controllability, but also improves the load capacity and durability of the transfer device, while enhancing the adaptability and flexibility of the transfer device, so that the transfer device can meet the needs of various terrains or complex transfer areas.

[0062] Specifically, the two moving wheels 21 are rotatably connected to one end of the frame 1 close to the handle 8, and the two fixed wheels 22 are rotatably connected to one end of the frame 1 away from the handle 8. The moving wheels 21 have high flexibility and can easily change direction. The handle 8 and the moving wheels 21 are arranged at the same end, which can reduce the fatigue of the force applicator, so that the thrust can be applied more easily, especially when the direction needs to be changed or accelerated, which improves the convenience and comfort of the operation of the transfer device, and reduces the force transmission path, so that the transfer device can quickly respond to the change of direction, and improve the transfer efficiency of the material 9.

[0063] In this embodiment, the moving wheel 21 and the fixed wheel 22 are respectively a polyurethane moving wheel 21 and a polyurethane fixed wheel 22. The polyurethane material has excellent wear resistance and fatigue resistance, which enables the polyurethane moving wheel 21 and the polyurethane fixed wheel 22 to maintain stable performance during long-term use, resist wear and tear, reduce performance degradation and replacement frequency caused by wear, and thus extend the service life of the transfer device; the polyurethane material generates less noise during operation, so the polyurethane moving wheel 21 and the polyurethane fixed wheel 22 are quieter during operation, which helps to improve the working environment and reduce noise pollution; the polyurethane material has a high bearing capacity, so that the polyurethane moving wheel 21 and the polyurethane fixed wheel 22 can withstand greater weight and pressure, and provide better support for the frame 1; the polyurethane material has excellent elasticity and flexibility, so that the polyurethane moving wheel 21 and the polyurethane fixed wheel 22 can adapt to various complex environments and road conditions, can stably travel on uneven ground, reduce vibration and impact, improve the stability and reliability of the transfer device, further improve the stability of the material 9 during the transfer process, and help reduce the wear of the material 9.

[0064] Furthermore, in this embodiment, the wheel diameter of the moving wheel 21 and the fixed wheel 22 is 125 mm, the wheel width is 32 mm, the upper limit of the load is 140 kg, and the distance between the center of the moving wheel 21 and the fixed wheel 22 and the bottom surface of the frame 1 is 155 mm. The arrangement of the moving wheel 21 and the moving wheel 21 improves the carrying capacity of the transfer device, facilitates the transfer device to transfer more materials 9 at the same time, and improves the transfer efficiency of the materials 9 to a certain extent.

[0065] It is understandable that in other embodiments, the material, wheel diameter, wheel width, upper load limit and distance from the bottom surface of the frame 1 of the moving wheel 21 and the fixed wheel 22 can be adjusted according to actual needs.

[0066] Furthermore, in this embodiment, the side plate 6, the top plate 5a, the bottom plate 5b, and the back plate are 1.2mm thick galvanized plates; the length of the side where the door plate 7 and the back plate of the frame 1 are located is 870mm, the width of the side where the side plate 6 of the frame 1 is located is 570mm, and the height of the frame 1 is 1200mm; the length of the support plate 33 is 785mm, the width of the support plate 33 is 540mm, and the thickness of the support plate 33 is 10mm; the number of the placement holes 31 on the support plate 33 is 88, and the aperture of the placement holes 31 is 33mm. The size setting of the transfer device ensures that the transfer device has sufficient accommodation space and carrying capacity, and the overall design takes into account practicality, stability and durability.

[0067] It is understandable that in other embodiments, the sizes of the side panels 6 , the top panel 5 a , the bottom panel 5 b , the back panel, the frame 1 , the support plate 33 and the placement hole 31 may be adjusted according to actual needs.

[0068] The present embodiment provides a transfer device, which restricts the movement of materials by setting placement holes, so that materials are isolated from each other, avoiding mutual wear or collision between materials, ensuring the quality and durability of materials, and further improving the sealing of the system; by setting a pulley assembly, the frame can be conveniently moved between the transfer starting point and the destination, greatly improving the efficiency of material transfer operations, while improving the smoothness of material movement, effectively avoiding the risk of materials escaping from the placement holes and colliding with each other due to bumps or shaking, and further improving the reliability of transfer operations.
