Description

Technical Field

[0001] The utility model relates to the technical field of building material transportation, and particularly relates to a material suspension cage. Background Art

[0002] During the construction of a building, relevant building materials often need to be transported. For example, bricks, wood, etc. need to be transported from the ground to the corresponding construction floors. And due to a certain height, it is difficult to complete the transportation work only by manpower. Therefore, ropes, pulleys, elevators, etc. are used for the transportation of building materials. However, this transportation method cannot effectively fix or limit the materials during transportation, which is likely to cause accidents and does not meet safety specifications.

[0003] So now, suspension cages are used at the construction site to transport materials. The suspension cage is also called a hanging cage, a herringbone cage, a worker's hanging cage, etc., and is a framework spliced by wire meshes. Materials are placed inside the suspension cage and then lifted to the designated height by a hoisting device. However, the sizes of existing suspension cages are usually fixed, which limits the quantity and especially the size of the transported materials. Summary of the Utility Model

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect that the size of the material suspension cage in the prior art cannot be adjusted, which limits the quantity and especially the size of the materials to be transported, so as to provide a material suspension cage whose size can be adjusted according to the quantity and size of the materials to be transported.

[0005] To solve the above problems, the utility model provides a material suspension cage, including:

[0006] An adjustable frame, which is telescopically arranged along a first direction and a second direction. The first direction is parallel to any side of the adjustable frame, and the second direction is perpendicular to the first direction;

[0007] Four groups of enclosure components, wherein two groups of the enclosure components are telescopically arranged along the first direction on two sides of the adjustable frame parallel to the first direction, and the other two groups of the enclosure components are telescopically arranged along the second direction on two sides of the adjustable frame perpendicular to the first direction, and the bottom ends of the enclosure components are connected to the adjustable frame;

[0008] A limiting component, the limiting component includes limit members arranged along the first direction and / or the second direction, and two ends of the limit members are connected to the adjustable frame.

[0009] Optionally, the adjustment frame includes: four right-angle frames and four connecting frames. The four right-angle frames are arranged at the four corners of the adjustment frame, and one connecting frame is arranged between two adjacent right-angle frames. Both ends of the connecting frame are slidably connected to the corresponding two right-angle frames.

[0010] Optionally, a plurality of first positioning holes are provided on the right-angle frame and the connecting frame, and a first locking member is provided in the first positioning holes corresponding to the right-angle frame and the connecting frame.

[0011] Optionally, the enclosure assembly includes: two main enclosures and a sub-enclosure. The bottom end of the main enclosure is connected to the adjustment frame, and both ends of the sub-enclosure are slidably connected to the two main enclosures.

[0012] Optionally, second positioning holes are provided at the top end and / or the bottom end of the main enclosure and the sub-enclosure, and a second locking member is provided in the second positioning holes corresponding to the main enclosure and the sub-enclosure.

[0013] Optionally, the main enclosure includes: a semi-frame and a first retaining net, and the outer periphery of the first retaining net is connected to the semi-frame.

[0014] Optionally, the sub-enclosure includes: a full-frame and a second retaining net, and the outer periphery of the second retaining net is connected to the full-frame.

[0015] Optionally, the limiting member is a screw rod, a connecting nut is provided on the adjustment frame, and the screw rod is threadedly connected to the connecting nut.

[0016] Optionally, the material cage further includes a lifting assembly provided on two opposite groups of the enclosure assemblies, and the lifting assembly includes a lifting connecting member.

[0017] Optionally, the lifting connecting member includes: a connecting rod and lifting rings provided at both ends of the connecting rod. The lifting ring located at the bottom end of the connecting rod is connected to the limiting member.

[0018] The utility model has the following advantages:

[0019] 1. The material cage provided by the utility model includes an adjustment frame, four groups of enclosure components, and a limit component. The adjustment frame can be telescoped in a first direction and a second direction, thereby changing the size of the frame. The first direction is parallel to any side of the adjustment frame, and the second direction is perpendicular to the first direction, that is, the telescoping direction of the adjustment frame cannot be its diagonal direction. The four groups of enclosure components surround the adjustment frame, and the bottom ends of the enclosure components are connected to the adjustment frame. Two of the groups of enclosure components are telescopically arranged along the first direction on two sides of the adjustment frame parallel to the first direction, so that when the adjustment frame is telescoped in the first direction, the enclosure components can also be telescopically adjusted accordingly. The other two groups of enclosure components are telescopically arranged along the second direction on two sides of the adjustment frame perpendicular to the first direction, so that when the adjustment frame is telescoped in the second direction, the enclosure components can also be telescopically adjusted accordingly. The limit component includes limit members arranged along the first direction and / or the second direction, and both ends of the limit members are connected to the adjustment frame. At the construction site, materials are often placed on a prefabricated chassis. When transportation is required, they can be transferred through the material cage. First, the cage is lifted by a hoisting device so that the enclosure components cover the periphery of the prefabricated chassis. Then, the bottom surface of the prefabricated chassis presses on the limit members, and the prefabricated chassis and the materials placed on it can be directly transferred away as a whole. This reduces the procedures for material loading and unloading. And since the adjustment frame can adjust its size and the enclosure components can also be adjusted accordingly with the change of the adjustment frame, the overall size and space of the material cage can be changed according to the quantity and size of the transported materials, and the applicable range is wider.

[0020] 2. For the material cage provided by the utility model, the adjustment frame includes four right-angle frames and four connecting frames. The four right-angle frames are arranged at the four corners of the adjustment frame, and a connecting frame is arranged between two adjacent right-angle frames. Both ends of the connecting frame are slidably connected to the corresponding two right-angle frames. By changing the distance between the two right-angle frames on both sides of the connecting frame, the size adjustment of the adjustment frame can be achieved, which is convenient, fast, and highly practical.

[0021] 3. For the material cage provided by the utility model, a plurality of first positioning holes are provided on the right-angle frames and the connecting frames, and first locking members are provided in the first positioning holes corresponding to the right-angle frames and the connecting frames. When the size of the adjustment frame needs to be adjusted, the first locking members are removed and the positions of the right-angle frames are adjusted. After the adjustment is completed, by setting the first locking members in the first positioning holes corresponding to the right-angle frames and the connecting frames, the shape of the adjustment frame is maintained, and the right-angle frames and the connecting frames are limited and locked and can no longer slide. This can ensure safety during use.

[0022] 4. The material cage provided by the present utility model, the enclosure assembly includes: two main enclosures and a secondary enclosure. The bottom end of the main enclosure is connected to the adjustment frame, and both ends of the secondary enclosure are slidably connected to the two main enclosures. Second positioning holes are provided at the top and / or bottom end of the main enclosure and the secondary enclosure, and second locking members are provided in the corresponding second positioning holes of the main enclosure and the secondary enclosure. After the enclosure assembly is adjusted to a proper position, the positions of the main enclosure and the secondary enclosure can be locked by the second locking members, ensuring that the enclosure assembly can cover the materials and guaranteeing the safety during the transportation process.

[0023] 5. The material cage provided by the present utility model, the limiting member is a screw rod, a nut is provided on the adjustment frame, and the screw rod is threadedly connected to the nut. After the material cage lifts the goods, the limiting member supports from below the precast chassis, and the screw rod is locked by being threadedly connected to the nut on the adjustment frame, improving the safety when transporting materials.

[0024] 6. The material cage provided by the present utility model, the material cage further includes a lifting assembly provided on two sets of opposite enclosure assemblies, and the lifting assembly includes a lifting connecting member. The lifting connecting member includes: a connecting rod and lifting rings provided at both ends of the connecting rod. The lifting ring located at the bottom end of the connecting rod is connected to the limiting member, and the lifting ring located at the top end can be directly connected to the hoisting equipment, facilitating the overall hoisting of the material cage and the materials.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0039] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0040] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0041] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0042] like Figures 1 to 3 As shown, it is a preferred embodiment of the material cage of the utility model, which can be used in construction sites to transport materials such as bricks and wood to floors of corresponding heights. In addition, the size of the material cage can be adjusted and will not be limited by the quantity and size of the materials.

[0043] The material cage comprises: an adjustment frame 1, four groups of enclosure components 2 and a limit component. The adjustment frame 1 is in the shape of a square frame and can be extended and retracted in a first direction and a second direction, thereby changing the size of the frame. The first direction is parallel to any side of the adjustment frame 1, and the second direction is perpendicular to the first direction, that is, the adjustment frame 1 is extended and retracted along the edge of the frame, and cannot be extended and retracted in the diagonal direction of the frame. The four groups of enclosure components 2 surround the adjustment frame 1, and the bottom ends of the enclosure components 2 are connected to the adjustment frame 1, that is, the bottom ends of the four groups of enclosure components 2 are respectively connected to the four sides of the adjustment frame 1. When the material cage is used to transport materials, the four groups of enclosure components 2 can protect the materials on all sides. Two groups of enclosure components 2 are arranged on the two sides of the adjustment frame 1 parallel to the first direction in a telescopic manner along the first direction, so that when the adjustment frame 1 is extended and retracted along the first direction, the enclosure components 2 can also be extended and retracted accordingly, and the other two groups of enclosure components 2 are arranged on the two sides of the adjustment frame 1 perpendicular to the first direction in a telescopic manner along the second direction, so that when the adjustment frame 1 is extended and retracted along the second direction, the enclosure components 2 can also be extended and retracted accordingly. That is to say, the enclosure assembly 2 is also retractable. When the adjustment frame 1 is retracted in the first direction and / or the second direction, the enclosure assembly 2 will also be retracted and adjusted accordingly. The limiting assembly includes a limiting member 301 arranged in the first direction and / or the second direction, and both ends of the limiting member 301 are connected to the adjustment frame 1. Specifically, the materials at the construction site are generally placed on a prefabricated chassis rather than directly on the ground. Taking bricks as an example, the bricks will be stacked and placed on a wooden prefabricated chassis. When transporting bricks, the connected adjustment frame 1 and the enclosure assembly 2 are lowered from directly above the bricks, so that the enclosure assembly 2 is covered around the bricks, and then the limiting member 301 is passed through the bottom of the prefabricated chassis. After that, the material cage is lifted as a whole, and the prefabricated chassis and the bricks placed thereon are pressed on the limiting member 301, and can be lifted together with the material cage. Compared with the existing cage with bottom, this material cage eliminates the step of moving materials from the prefabricated chassis to the cage, which can reduce the workload and save working hours. In addition, since the adjustment frame 1 and the enclosure assembly 2 can be adjusted and retracted to change the size, it can be adaptively changed according to the size of the prefabricated chassis and the quantity and size of the materials, etc., which is flexible and has a wide range of applications.

[0044] Furthermore, the adjustment frame 1 includes: four right-angle frames 101 and four connecting frames 102. The four right-angle frames 101 are arranged at the four corners of the adjustment frame 1, and one connecting frame 102 is arranged between two adjacent right-angle frames 101. Both ends of the connecting frame 102 are slidably connected to the corresponding two right-angle frames 101. Specifically, as Figure 4 shown, the right-angle frame 101 is composed of two vertically arranged square tubes, and the ends of the two square tubes are connected, which can be welded or integrally formed. A plurality of first positioning holes are formed in the right-angle frame 101. In this embodiment, the first positioning holes penetrate through the upper and lower sides of the right-angle frame 101, and the hole pitches of the first positioning holes are equal.

[0045] The connecting frame 102 is in an "I" shape, and both ends are slidably connected to the two right-angle frames 101 respectively. The connecting frame 102 is also in a square tube shape, but the outer dimension of the connecting frame 102 is smaller than that of the right-angle frame 101, so that the connecting frame 102 can be inserted into the right-angle frame 101. First positioning holes are also formed in the connecting frame 102. In this embodiment, the first positioning holes penetrate through the upper and lower sides of the connecting frame 102, the pitches of the first positioning holes are equal, and the hole pitches of the first positioning holes on the right-angle frame 101 are equal to the hole pitches of the first positioning holes on the connecting frame 102.

[0046] To ensure safety during the construction process, a first locking member 103 is provided in the first positioning holes corresponding to the right-angle frame 101 and the connecting frame 102. In this embodiment, the first locking member 103 is preferably a bolt and nut. After the adjustment of the right-angle frame 101 is completed, the bolt is passed through the first positioning holes corresponding to the right-angle frame 101 and the connecting frame 102, and then the nut is tightened at one end of the bolt. In this way, the positions of the right-angle frame 101 and the connecting frame 102 are fixed and no relative displacement can occur. When transporting materials, the size of the adjustment frame 1 will no longer change. When it is necessary to adjust the relative positions of the right-angle frame 101 and the connecting frame 102, the bolt and nut can be removed first.

[0047] The adjustment frame 1 is assembled by four right-angle frames 101 and four connecting frames 102. Each right-angle frame 101 can expand and contract along the extension directions of the two connecting frames 102 connected thereto. The minimum size of the adjustment frame 1 is when the connecting frames 102 are completely located within the right-angle frames 101. At this time, the shape of the adjustment frame 1 is a square, and the side length is the sum of the lengths of the two sides of the right-angle frame 101. During the telescopic adjustment, it can be telescoped in the first direction alone, or in the second direction alone, or in both the first and second directions. After the telescopic adjustment in the first direction or the second direction alone, the shape of the adjustment frame 1 is a rectangle; after the telescopic adjustment in both the first and second directions, the shape of the adjustment frame 1 is still a square, and the side length is increased compared to the minimum size state. After the adjustment is completed, through the cooperation of the first positioning holes and the first locking member 103, it is ensured that the adjusted size will not change, so as to ensure the safety during use.

[0048] In other embodiments, the adjustment frame 1 can also be composed of four sets of telescopic frames. The telescopic frames are in the shape of "one", and the four sets of telescopic frames enclose a square. Each set of telescopic frames consists of two slidably connected sliding members.

[0049] In other embodiments, it can also be that the outer dimension of the connecting frame 102 is larger than that of the right-angle frame 101, and both ends of the right-angle frame 101 slide within the connecting frame 102.

[0050] In other embodiments, the pitch of the first positioning holes on the right-angle frame 101 can also be gradually changed, either gradually increasing or gradually decreasing. The pitch of the first positioning holes on the connecting frame 102 can also be gradually changed, but it should correspond to the first positioning holes on the right-angle frame 101.

[0051] In other embodiments, the first positioning holes can also be opened on the sides of the right-angle frame 101 and the connecting frame 102.

[0052] In other embodiments, the first locking member 103 can also be a pin or the like.

[0053] In other embodiments, it can also be that slots are opened on the sides of the right-angle frame 101 and the connecting frame 102, and the limit is achieved by inserting a clamping plate into the corresponding slots of the right-angle frame 101 and the connecting frame 102.

[0054] In addition, in this embodiment, a connecting nut 302 is provided on the adjustment frame 1. The limiting member 301 is preferably a screw rod, and the screw rod is threadedly connected to the connecting nut 302. And four screw rods are provided, all arranged along the first direction.

[0055] Of course, in other embodiments, the number of screw rods can be two, three, six, etc.; the screw rods can also be arranged along the second direction, or a part is arranged along the first direction and another part is arranged along the second direction.

[0056] Furthermore, as Figure 5 shown, the enclosure assembly 2 includes: two main enclosures 201 and a secondary enclosure 202. The two main enclosures 201 in each group of enclosure assemblies 2 are mirror - set. The bottom end of the main enclosure 201 is connected to the adjustment frame 1, and both ends of the secondary enclosure 202 are slidably connected to the two main enclosures 201. When adjusting, the adjustment frame 1 can change its size by changing the position of the right - angle frame 101. Correspondingly, the enclosure assembly 2 can change its size by changing the position of the main enclosure 201.

[0057] The main enclosure 201 includes: a semi - frame 2011 and a first retaining net 2012. The outer periphery of the first retaining net 2012 is connected to the semi - frame 2011. As Figure 6 shown, since one side needs to be connected to the secondary enclosure 202, the semi - frame 2011 only has three side - frames. The first retaining net 2012 is arranged in the area enclosed by the semi - frame 2011 and is connected to the semi - frame 2011. In this embodiment, the first retaining net 2012 is a metal net structure with a plurality of diamond - shaped mesh holes.

[0058] In other embodiments, the first retaining net 2012 can also be a metal net structure with a plurality of square holes.

[0059] The secondary enclosure 202 includes: a full - frame 2021 and a second retaining net 2022. The outer periphery of the second retaining net 2022 is connected to the full - frame 2021. As Figure 7 shown, the full - frame 2021 has four side - frames. The second retaining net 2022 is arranged in the area enclosed by the four side - frames and is connected to the full - frame 2021. In this embodiment, the second retaining net 2022 is a metal net structure with a plurality of diamond - shaped mesh holes.

[0060] In other embodiments, the second retaining net 2022 can also be a metal net structure with a plurality of square holes.

[0061] Moreover, in this embodiment, the connection method between the secondary enclosure 202 and the main enclosure 201 is similar to the connection method between the connecting frame 102 and the right - angle frame 101. The secondary enclosure 202 can slide inside the main enclosure 201. Of course, in other embodiments, it can also be that the main enclosure 201 slides inside the secondary enclosure 202.

[0062] The top end and / or bottom end of the main enclosure 201 and the secondary enclosure 202 are both provided with second positioning holes, and second locking members 203 are arranged in the corresponding second positioning holes of the main enclosure 201 and the secondary enclosure 202. The main enclosure 201 and the secondary enclosure 202 are limited and locked through the cooperation of the second positioning holes and the second locking members 203. Specifically, in this embodiment, the top end and the bottom end of the main enclosure 201 and the secondary enclosure 202 are both provided with second positioning holes, that is, through second positioning holes are arranged on both frames on the upper and lower sides of the semi-frame 2011 of the main enclosure 201, and through second positioning holes are also arranged on both frames on the upper and lower sides of the full-frame 2021 of the secondary enclosure 202, and the hole pitches of the second positioning holes on the main enclosure 201 and the secondary enclosure 202 are equal. After the sliding adjustment of the main enclosure 201 is completed, the second locking members 203 are arranged in the corresponding second positioning holes of the main enclosure 201 and the secondary enclosure 202, and the limit locking can be achieved. The second locking members 203 are also preferably bolts and nuts.

[0063] In other embodiments, the main enclosure 201 and the secondary enclosure 202 may be provided with second positioning holes only at the top end or the bottom end.

[0064] In other embodiments, the hole pitch of the second positioning holes on the main enclosure 201 may also be gradually changed, and it may gradually increase or gradually decrease. The hole pitch of the second positioning holes on the secondary enclosure 202 may also be gradually changed, but it should correspond to the second positioning holes on the main enclosure 201.

[0065] In other embodiments, the second positioning holes may also be opened on the sides of the main enclosure 201 and the side enclosures.

[0066] In other embodiments, the second locking members 203 may also be dowel pins or the like.

[0067] In other embodiments, slots may also be opened on the sides of the main enclosure 201 and the side enclosures, and the limit is achieved by inserting a clamping plate into the corresponding slots of the main enclosure 201 and the side enclosures.

[0068] The material cage further includes a lifting assembly arranged on two sets of opposite enclosure assemblies 2, and the lifting assembly includes a lifting connecting member 401. In this embodiment, four lifting connecting members 401 are arranged at intervals on two sets of opposite enclosure assemblies 2.

[0069] In other embodiments, the lifting assembly may also be arranged on the other two sets of opposite enclosure assemblies 2, or the lifting assembly may be arranged on all four sets of enclosure assemblies 2. And the number of the lifting connecting members 401 included in the lifting assembly may also be one, two, five, etc.

[0070] Specifically, the lifting connecting member 401 includes: a connecting rod and sling rings 4011 provided at both ends of the connecting rod. The axial direction of the connecting rod is parallel to the height direction of the enclosure assembly 2, and the connecting rod can be directly welded to the outside of the main enclosure 201. The sling ring 4011 at the bottom end of the connecting rod is connected to the limiting member 301, and the sling ring 4011 at the top end of the connecting rod is connected to the lifting device. The provision of the lifting connecting member 401 facilitates directly lifting away the cage and materials together.

[0071] The usage method of the material cage provided in this embodiment is described as follows:

[0072] First, it is necessary to adjust the size of the cage according to the size of the precast chassis. When adjusting, the adjusting frame 1 and the enclosure assembly 2 need to be adjusted separately. When adjusting the adjusting frame 1, the first locking member 103 needs to be removed first, then the right-angle frame 101 is slid to the appropriate position, and then the first locking member 103 is set in the corresponding first positioning holes of the right-angle frame 101 and the connecting frame 102. The adjustment of the enclosure assembly 2 is the same as that of the adjusting frame 1. The second locking member 203 needs to be removed first, then the main enclosure 201 is slid to the appropriate position, and then the second locking member 203 is set in the corresponding second positioning holes of the main enclosure 201 and the sub-enclosure 202. Moreover, since the main enclosure 201 and the right-angle frame 101 are connected together and can move synchronously, in actual adjustment, after removing the first locking member 103 and the second locking member 203, the adjusting frame 1 and the enclosure assembly 2 can be adjusted synchronously.

[0073] After the adjustment is completed, the cage is lifted above the precast chassis and slowly lowered. When the adjusting frame 1 reaches the precast chassis, the limiting member 301 is started to be set. The limiting member 301 sequentially passes through the sling ring 4011 on one side of the enclosure assembly 2, the connecting nut 302 on one side of the adjusting frame 1 to the sling ring 4011 and the connecting nut 302 on the opposite side. Then the whole can be lifted. At this time, the precast chassis is supported by the limiting member 301, and the surrounding is protected by the enclosure assembly 2 to prevent the materials from falling during the rising process.

[0074] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
