[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] It should be understood that:

[0032] The equipment used in optical cable production needs to be lifted before transportation so that it can be placed on a forklift or trailer. However, some equipment is very heavy or has no handles, such as racks, stacked box switches, and packaged wooden boxes. Since cranes cannot be installed indoors (in an environment where cranes or other lifting devices cannot be set up), they need to be disassembled before transportation, or multiple people need to work together to lift them, which increases the transportation time.

[0033] In addition, the irregular shapes of some production equipment also result in a lack of good force points for lifting, making lifting inconvenient and increasing transportation time.

[0034] The embodiment of the present application provides an equipment lifting device to solve the problem in the related art that when lifting production equipment indoors, the production equipment has an irregular shape, has no stable force points, and is inconvenient to lift.

[0035] See also Figure 1 , an equipment lifting device, comprising:

[0036] A flexible strap 1, one side of which in the thickness direction is provided with an elastic friction member 2, and the other side of which is provided with a plurality of connecting members 3 distributed along its length direction;

[0037] A tensioner 4, which is fixedly connected to one end of the flexible strap 1 and is used to form the flexible strap 1 into a binding ring;

[0038] A plurality of lifting structures 5 are detachably connected to the connecting members 3 to lift the tying rings.

[0039] The above structure can conform to the equipment of different shapes through the characteristics of the flexible strap 1, and cooperate with the elastic friction part 2 to improve the static friction between the equipment and the use of the tensioner 4, so that the flexible strap 1 forms a strapping ring that is firmly connected to the equipment; in addition, the lifting structure 5 can lift the strapping ring and the equipment through the connecting part 3, so that the strapping ring can provide a stable force point for equipment of different shapes, which is convenient for the lifting structure 5 to lift, and at the same time does not require the use of a lifting device, the structure is simple, and it is convenient for a forklift or a trailer to transport the equipment.

[0040] For contour fitting with devices of different shapes, please refer to Figure 3 and Figure 4 Status description, Figure 3 The device in the middle is a square. Figure 4 When the circular equipment, such as the racks, stacked box switches, and packaged wooden boxes described above, needs to be lifted for forklift transportation, if it is placed on a pallet, the above problems do not need to be considered. However, if it is not placed on a pallet and traditional lifting equipment is used, the following problems will occur:

[0041] First, it is inconvenient to operate indoors and it occupies a large space indoors; second, the use of lifting equipment is cumbersome and the investment cost is also high; third, the appearance of the equipment varies and no effective and stable lifting point can be provided. Therefore, the equipment lifting device of the present application uses a flexible strap 1 and an elastic friction member 2 to strap to the equipment, which can provide a stable lifting point, and then multiple lifting structures 5 are used for lifting; the number of the above lifting structures 5 can be based on different lifting requirements and space requirements. For example, equipment with heavier weight or larger volume uses more lifting structures 5 to ensure the lifting force; for example, the space outside the equipment for operation is small, and a suitable number of lifting structures 5 can be flexibly placed to connect with the connector 3.

[0042] Among them, the elastic friction member 2 adopts an elastic member to facilitate the contour fitting with the equipment without causing damage to the equipment, and provide a large static friction force to achieve the problem of not falling during the lifting process.

[0043] In some preferred implementations, the materials of the elastic friction member 2 and the flexible strap 1 are described in detail:

[0044] The elastic friction member 2 is made of silicone rubber; the flexible strap 1 is made of nylon webbing. The elastic friction member 2 includes high-resistance materials, such as silicone rubber and other high-damping materials, which provide static friction to lift the object after being pressed against the object. The flexible strap 1 includes a strip of high-toughness material, such as nylon webbing, etc., which is used to connect the tensioner 4 to fix the damping material.

[0045] The above high-resistance materials refer to materials that can provide friction. The material of the elastic friction member 2 of the present application includes but is not limited to silicone rubber; the flexible strap 1 includes but is not limited to nylon webbing.

[0046] For further information, please refer to Figure 1 The elastic friction member 2 is a rectangular sheet structure, and its size is smaller than or equal to the flexible strap 1 .

[0047] There are multiple elastic friction members 2, and they are distributed along the length direction of the flexible strap 1. This structural form can also increase the static friction force, and can be selected according to needs.

[0048] Furthermore, the tensioner 4 is an existing product, and its specific structure can be referred to Chinese patent CN 216186283U; the method of use during the tensioning process is: fix one end of the flexible strap 1 on the fixed column, pass the other flexible strap 1 through the rotating shaft, and the user holds the handle and flips the rotating frame back and forth, so that the ratchet rotates, and then drives the rotating shaft to rotate, thereby tightening the flexible strap 1. When it is necessary to relax the flexible strap 1, the limit plate is disengaged from the ratchet by pulling the sleeve, and then the safety plate is turned to disengage it from the ratchet. The ratchet rotates under the action of the flexible strap 1, thereby completing the relaxation of the flexible strap 1.

[0049] In some preferred embodiments, the specific structural form of the connector 3 can realize a detachable connection, and the following description is made:

[0050] Form 1

[0051] The connecting member 3 includes a vertical plate 300, on which connecting screw holes are arranged; a connecting block is fixedly arranged at the lifting end of the top of the lifting structure 5, on which bolts connected to the connecting screw holes are arranged.

[0052] Form 2

[0053] refer to Figure 2 and Figure 1 As shown, the connecting member 3 includes a vertical plate 300, on which a T-shaped slot 301 extending upward from the bottom end thereof is provided, and the extension length of the T-shaped slot 301 is less than the length of the vertical plate 300; a T-shaped block 500 is movably provided in the T-shaped slot 301; and the lifting end at the top of the lifting structure 5 is fixedly connected to the T-shaped block 500. The T-shaped block 500 and the T-shaped slot 301 are matched.

[0054] Form Three

[0055] The connecting member 3 comprises a vertical plate 300, on which a connecting ring is provided;

[0056] The lifting end at the top of the lifting structure 5 is provided with a U-shaped rod and a connecting rod, and mounting holes are provided on both ends of the U-shaped rod; the connecting rod passes through the mounting holes and is connected to the U-shaped rod through a nut to form a hook structure for connecting to the connecting ring.

[0057] The above three forms can all achieve detachable connection, but the connecting member 3 includes but is not limited to the above structural forms.

[0058] In some preferred embodiments, the lifting structure 5 includes a base, on which a vertically arranged digital hydraulic cylinder is disposed. Alternatively, the lifting structure 5 includes a base, on which a vertically arranged rack jack is disposed.

[0059] This kind of structure is relatively simple, and lifting can be achieved by simply using a digital hydraulic cylinder or a rack jack that can be raised and lowered. However, it has the defect that it is not convenient to connect to the top of the hydraulic cylinder, so there are also the following settings:

[0060] refer to Figure 5 The lifting structure 5 is also provided with a sleeve 6 located above the base, the top of the sleeve 6 is sealed and the bottom is open; the top of the lifting structure 5 supports the inner top wall of the sleeve 6. The sleeve 6 can be fixedly connected to the top of the lifting structure 5, for example, by welding.

[0061] Then, corresponding to the first form of the connecting member 3, a connecting block can be provided outside the sleeve 6; corresponding to the second form of the connecting member 3, a T-block 500 can be provided outside the sleeve 6; corresponding to the second form of the connecting member 3, a U-shaped rod can be provided outside the sleeve 6.

[0062] The steps for using the equipment lifting device of this application are roughly as follows:

[0063] Step 1: Wrap the flexible strap 1 around the object or equipment to be lifted, and fit the elastic friction member 2 to the object or equipment;

[0064] Step 2: Place one end of the flexible strap 1 into the tensioner 4 to form a binding loop, and then tighten it through the tensioner 4 to reduce the binding loop so that the fixing device is tightly tied to the object or equipment.

[0065] Step 3: According to the volume and weight of the object or equipment, and the size of the space that can be constructed by the on-site lifting operation, obtain a corresponding number of lifting structures 5, and then connect them to the flexible strap 1 through the connecting piece 3.

[0066] Step 4: The lifting structure 5 is lifted. After the object or equipment is lifted to a certain height, the connecting member 3 and the lifting structure 5 are disassembled, and then the object or equipment is transferred by a forklift.

[0067] Beneficial effects of this application:

[0068] Due to the characteristics of the flexible strap 1, it can be contoured and fitted with equipment of different shapes. The elastic friction member 2 is used to increase the static friction between the strap and the equipment, and the tensioner 4 is used to make the flexible strap 1 form a strapping ring that is firmly connected to the equipment. In addition, the lifting structure 5 can lift the strapping ring and the equipment through the connecting member 3, so that the strapping ring can provide a stable force point for equipment of different shapes, which is convenient for the lifting structure 5 to lift. At the same time, there is no need to use a lifting device, the structure is simple, and it is convenient for a forklift or a trailer to transport the equipment.

[0069] For contour fitting with devices of different shapes, please refer to Figure 3 and Figure 4 Status description, Figure 3 The device in the middle is a square. Figure 4 When the circular equipment, such as the racks, stacked box switches, and packaged wooden boxes described above, needs to be lifted for forklift transportation, if it is placed on a pallet, the above problems do not need to be considered. However, if it is not placed on a pallet and traditional lifting equipment is used, the following problems will occur:

[0070] First, it is inconvenient to operate indoors and it occupies a large space indoors; second, the use of lifting equipment is cumbersome and the investment cost is also high; third, the appearance of the equipment varies and no effective and stable lifting point can be provided. Therefore, the equipment lifting device of the present application uses a flexible strap 1 and an elastic friction member 2 to strap to the equipment, which can provide a stable lifting point, and then multiple lifting structures 5 are used for lifting; the number of the above lifting structures 5 can be based on different lifting requirements and space requirements. For example, equipment with heavier weight or larger volume uses more lifting structures 5 to ensure the lifting force; for example, the space outside the equipment for operation is small, and a suitable number of lifting structures 5 can be flexibly placed to connect with the connector 3.

[0071] Among them, the elastic friction member 2 adopts an elastic member to facilitate the contour fitting with the equipment without causing damage to the equipment, and provide a large static friction force to achieve the problem of not falling during the lifting process.
