Description

Technical Field

[0001] The utility model relates to the field of tools, in particular to an automatic steel coil masking tool. Background Art

[0002] In order to facilitate storage and transportation, some steel raw materials are rolled into cylindrical steel coils. When using containers to transport steel coils, in order to ensure that the goods are stored in place and stable in the container during transportation, it is often necessary to use corner wood and other padding materials to wedge under the arc surface of the steel coil in the direction of easy rolling. This process is mainly operated manually. When personnel are padding in the box, forklifts and other loading and unloading equipment also need to enter the narrow container to load the steel coil into the designated position in the box. Forklifts and personnel are working in the container at the same time, which poses a great safety risk. In addition, due to the unstable working site and the small space in the container, there is no reliable and convenient tool to replace manual labor for a long time. In order to solve the above problems, it is urgent to develop an automatic padding tool for steel coils to replace the work of personnel in the box. Utility Model Content

[0025] The beneficial effect of adopting the above-mentioned further scheme is that the switch device clamps the slot on the secondary telescopic push rod through the teeth, thereby locking or popping open the primary push rod and the secondary push rod, ensuring the stability and safety of the push rod assembly when not in use. When automatic covering is required, the teeth are disengaged from the slot by triggering one end of the switch device connected to the compression spring, and the push rod assembly can automatically pop open under the action of the internal spring force, thereby achieving quick unlocking and extension, and improving the convenience of operation.

[0044] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0045] like Figure 1-3As shown, the utility model provides an automatic steel coil padding tool, including: a telescopic push rod assembly 14 and a limit assembly 15, wherein the telescopic push rod assembly 14 includes: a telescopic push rod seat 1 and a multi-section push rod assembly arranged in the telescopic push rod seat 1, one end of the telescopic push rod seat 1 is provided with an opening, and the end is an open end, and the multi-section push rod assembly can extend from the open end of the telescopic push rod seat 1 to achieve the extension of the rod body. At the same time, a push plate 11 is provided at the head end of the push rod assembly, and the padding material can be stored in the push plate 11, so that in the process of extending the multi-section push rod assembly, the telescopic push rod assembly 14 can push the padding material to be tangent to the arc surface of the steel coil 12, so as to achieve the automatic placement of the padding.

[0046] When the telescopic push rod assembly 14 does not need to be extended, the position of the multi-section push rod assembly needs to be fixed by the limiting assembly 15. Specifically, the limiting assembly 15 is arranged on the outer wall of the telescopic push rod seat 1 on one side close to the opening end.

[0047] During operation, the cushioning tool is directly set near the steel coil 12 in the container 13, wherein one end of the cushioning tool is against the side wall of the container 13, and the other end is toward the position of the goods that need cushioning. The cushioning material 10 can be made of materials such as triangular wood. The cushioning material 10 is placed in the push plate 11 at the head end of the push rod assembly and keeps a certain distance from the steel coil 12. By extending the multi-section push rod assembly in the cushioning tool to the maximum length, the telescopic direction of the multi-section push rod assembly is parallel to the radial direction of the steel coil 12. During the extension of the multi-section push rod assembly, the push plate 11 pushes the triangular wood to embed under the arc surface of the easy rolling direction of the steel coil 12. The cushioning material 10 is tangent to the arc surface of the steel coil 12 and fits firmly, representing that the wedge is put into place.

[0048] The automatic padding tool is used to replace personnel in manually padding the materials of the steel coil 12 in place during the loading and unloading operation of the steel coil 12, which solves the problem of large safety risks in traditional manual padding operations. The multi-section push rod assembly is extended to ensure that the padding material 10 is placed in place and fits firmly with the steel coil 12, thereby ensuring the stability and safety of the goods and achieving remote control. The use process is convenient, efficient and safe, and the structure is simple, light weight, small size, easy to operate, easy to use and daily inspection and maintenance, with high reliability and wide applicability.

[0049] like Figure 1 , Figure 4As shown, in the preferred embodiment, the telescopic push rod seat 1 is a hollow long tube structure, one end of which is closed and the other end is open, that is, the other end is an open end. The push rod assembly installed in the telescopic push rod seat 1 includes: a primary push rod 2, a primary spring 3, a secondary push rod 4 and a secondary spring 5. The primary push rod 2, the primary spring 3, the secondary push rod 4 and the secondary spring 5 are all arranged in the telescopic push rod seat 1, and are assembled with the telescopic push rod seat 1 to form the main structure of the telescopic push rod assembly 14. It can be imagined that the number of sections of the push rod assembly can be set as needed to meet the needs of use. At the same time, the length and number of sections of the push rod assembly can also be adaptively adjusted according to the distance between the automatic masking tool and the steel coil 12, which is not limited here.

[0050] In the above scheme, multi-stage telescopic movement is achieved through the combination of the primary push rod 2, the primary spring 3, the secondary push rod 4 and the secondary spring 5. The setting of the primary spring 3 and the secondary spring 5 not only provides a reset function for the push rod assembly, but also plays a buffering role during the telescopic process.

[0051] In further schemes, such as Figure 1 As shown, the primary push rod 2 and the secondary push rod 4 are also hollow long tube structures, both of which are closed at one end and open at the other end. The primary push rod 2 and the primary spring 3 are both embedded in the telescopic push rod seat 1 and can slide relative to the inner cavity of the telescopic push rod seat 1. One end of the primary spring 3 contacts the inner side of the unopened end of the telescopic push rod seat 1, and the other end contacts the outer side of the unopened end of the primary push rod 2. That is, the primary spring 3 is arranged in the space enclosed by the bottom end of the primary push rod 2 and the inner cavity of the telescopic push rod seat 1. When the primary push rod 2 completely enters the telescopic push rod seat 1, the primary spring 3 is compressed, and when the primary push rod 2 is extended from the telescopic push rod seat 1, the primary spring 3 is compressed. When it reaches the farthest distance, the primary spring 3 is stretched; the secondary push rod 4 and the secondary spring 5 are both embedded in the primary push rod 2 and cooperate with the inner cavity gap of the primary push rod 2, and can slide relative to the inner wall of the primary push rod 2, one end of the secondary spring 5 contacts the inner side of the unopened end of the primary push rod 2, and the other end contacts the outer side of the unopened end of the secondary push rod 4, that is, the secondary spring 5 is arranged in the space enclosed by the bottom end of the secondary push rod 4 and the inner cavity of the primary push rod 2, when the secondary push rod 4 completely enters the primary push rod 2, the secondary spring 5 is compressed, and when the secondary push rod 4 extends from the primary push rod 2 to the farthest distance, the secondary spring 5 is stretched.

[0052] In the above scheme, the first-level push rod 2 and the first-level spring 3 are both embedded in the telescopic push rod seat 1, and the second-level push rod 4 and the second-level spring 5 are both embedded in the first-level push rod 2, which reduces the occupied space of the entire automatic masking tool. Through the nesting of the first-level push rod 2 and the second-level push rod 4, multi-stage telescopic movement is achieved.

[0053] like Figure 1As shown, in this embodiment, the length of the telescopic push rod seat 1 is greater than the length of the primary push rod 2, and the primary push rod 2 can compress the primary spring 3 from the open end of the telescopic push rod seat 1 so as to completely enter the telescopic push rod seat 1, and the tail end of the primary push rod 2 extending into the innermost part of the telescopic push rod seat 1 is provided with a primary clip, the size of the primary clip is greater than the size of the open end of the telescopic push rod seat 1, the primary push rod 2 and the primary spring 3 are respectively matched with the inner cavity gap of the telescopic push rod seat 1, and the open end of the telescopic push rod seat 1 and the part of the primary push rod 2 extending out of the telescopic push rod seat 1 are also matched with the gap, except that the primary push rod 2 and the telescopic push rod seat 1 can slide against each other in the axial direction of the telescopic push rod seat 1, there is no obvious activity clearance in other directions. When the primary push rod 2 is completely retracted into the telescopic push rod seat 1, the primary spring 3 is compressed, and when the primary push rod 2 moves to the farthest position, the primary spring 3 is not compressed and the primary clip at the tail end of the primary push rod 2 is placed in the telescopic push rod seat 1, and the primary spring 3 returns to the initial position.

[0054] like Figure 1 As shown, the length of the primary push rod 2 is greater than that of the secondary push rod 4. The secondary push rod 4 can compress the secondary spring 5 from the opening of the primary push rod 2 so that it can completely enter the primary push rod 2. The tail end of the secondary push rod 4 that goes deep into the innermost part of the primary push rod 2 is provided with a secondary clip. The size of the secondary clip is greater than the size of the opening of the primary push rod 2. The opening of the primary push rod 2 and the part of the secondary push rod 4 that extends out of the primary push rod 2 are slidable clearance fits. Except that the primary push rod 2 and the secondary push rod 4 can slide against each other along the axial direction of the telescopic push rod seat 1, there is no obvious activity clearance in other directions. When the secondary push rod 4 is completely retracted into the primary push rod 2, the secondary spring 5 is compressed. When the secondary push rod 4 moves to the farthest position, the secondary spring 5 is not compressed and the secondary clip at the tail end of the secondary push rod 4 is placed in the primary push rod 2. At this time, the secondary spring 5 returns to the initial position.

[0055] In the above scheme, the setting of the first-level bracket allows the first-level push rod 2 and the telescopic push rod seat 1 to freely telescope and expand with each other without separation, and the setting of the second-level bracket allows the first-level push rod 2 and the second-level push rod 4 to freely telescope and expand with each other without separation. When the first-level spring 3 is compressed, the first-level push rod 2 is retracted into the telescopic push rod seat 1, and when the first-level spring 3 is ejected, the first-level push rod 2 can be extended from the telescopic push rod seat 1 to the farthest position without separation; when the second-level spring 5 is compressed, the second-level push rod 4 is retracted into the first-level push rod 2, and when the second-level spring 5 is ejected, the second-level push rod 4 can be extended from the first-level push rod 2 to the maximum position without separation, thereby realizing the telescopic change in the length direction of the push rod through spring compression and extension.

[0056] like Figure 2 , Figure 3 , Figure 7As shown, in the preferred embodiment, the limit assembly 15 includes: a switch device 6, a remote control device 7, a base 8 and a connecting clip 9, wherein the switch device 6 and the remote control device 7 are both installed on the base 8, and the base 8 and the connecting clip 9 are installed on the outer wall of the telescopic push rod seat 1, and the position of the switch device 6 and the remote control device 7 is fixed by the connecting clip 9 and the base 8.

[0057] In the above scheme, the switch device 6 is controlled by the remote control device 7 to fix the position of the push rod assembly. When the push rod assembly needs to be extended, the remote control device 7 controls the switch device 6 to operate, so that the push rod assembly can automatically pop open under the action of the internal spring. When the push rod assembly does not need to be extended, the switch device 6 clamps the position of the push rod assembly to ensure that the push rod assembly is fixed after being retracted into the telescopic push rod seat 1; the connecting clip 9 and the base 8 realize the installation and fixation of the remote control device 7 and the switch device 6.

[0058] like Figure 8 As shown, the connecting clip 9 includes an arc-shaped arc body, and connecting platforms extend from both sides of the arc body respectively, and connecting holes are opened on the connecting platforms; in this embodiment, the base 8 adopts an irregular flat plate structure, and correspondingly, fixing holes are opened at corresponding positions where the base 8 and the connecting platform are installed. During installation, the arc body is covered on the outer wall of the telescopic push rod seat 1, and the two connecting platforms are respectively connected to the base 8 by fasteners.

[0059] In the above solution, the connecting clip 9 can be closely fitted on the outer wall of the telescopic push rod seat 1 through the arc body. The connecting clip 9 can effectively fix the base 8 and the telescopic push rod seat 1, and the connection method is simple.

[0060] like Figure 3 , Fig. 9 As shown, in the preferred solution, the remote control device 7 is installed in the installation box on the base 8, and the remote control device 7 specifically includes: a control switch and a telescopic top rod 71, the control switch is installed in the installation box, the telescopic top rod 71 extends out of the installation box and is arranged vertically in the length direction of the telescopic push rod seat 1, wherein the telescopic top rod 71 is an electric telescopic top rod 71, and in this embodiment, the electric telescopic top rod 71 can be a telescopic top rod 71 controlled by a cylinder, and the control switch is triggered to control the cylinder to control the movement of the telescopic top rod 71 to push the switch device 6. At the same time, it can be imagined that the remote control device 7 also includes a power supply system for powering the telescopic top rod 71, and the control device is powered by the power supply system, and the control device is remotely controlled by personnel.

[0061] In the above scheme, the switch device 6 is controlled by the control device, and then the push rod assembly is controlled to complete the automatic pad covering action.

[0062] like Figure 6 , Fig. 9As shown, in the preferred scheme, the switch device 6 is a rod with raised teeth at one end, and the other end of the switch device 6 is fixedly connected to one end of the compression spring 61, and the other end of the compression spring 61 is fixed to the telescopic push rod seat 1. In this embodiment, the switch device 6 is a slender structure, and the switch device 6 is arranged parallel to the length direction of the telescopic push rod seat 1; the switch device 6 is provided with an intermediate fulcrum in the middle of one side close to the telescopic push rod seat 1, and the intermediate fulcrum is connected to the telescopic push rod seat 1 in the form of a hinge, that is, the switch device 6 can rotate around the hinge connected to the telescopic push rod seat 1.

[0063] The switch device 6 is installed on the telescopic push rod seat 1 through the base 8 and the connecting clip 9. In the normal state, that is, when the push rod assembly is fully retracted into the telescopic push rod seat 1, the teeth on the switch device 6 can clamp the grooves on the secondary telescopic push rod to keep the primary push rod 2 and the secondary push rod 4 fixed after they are fully retracted. After the teeth on the switch device 6 are disengaged from the grooves, the push rod assembly can automatically pop open under the action of the internal spring force.

[0064] In the above scheme, the switch device 6 uses the teeth to clamp the slot on the secondary push rod, so as to lock or pop open the primary push rod 2 and the secondary push rod 4, ensuring the stability and safety of the push rod assembly when not in use. When automatic covering is required, the teeth are disengaged from the slot by triggering one end of the switch device 6 connected to the compression spring 61, and the push rod assembly can automatically pop open under the action of the internal spring force, realizing quick unlocking and extension, and improving the convenience of operation.

[0065] The specific working process is that when the primary push rod 2 and the secondary push rod 4 are fully retracted into the telescopic push rod seat 1, the teeth on the switch device 6 are inserted into the groove at the top of the secondary push rod 4, and the telescopic push rod 71 is loosely matched with one end of the spring of the switch device 6.

[0066] When the primary push rod 2 and the secondary push rod 4 extend out of the telescopic push rod seat 1, the telescopic push rod 71 moves to compress the compression spring 61 at one end of the switch device 6, releasing the switch device 6 from the normal state of disengaging from the slot, so that the teeth at the other end of the switch device 6 disengage from the slot on the secondary push rod 4.

[0067] In the above scheme, under normal conditions, the telescopic top rod 71 of the remote control device 7 is clearance-matched with one end of the spring of the switch device 6, and the telescopic top rod 71 pushes one end of the switch device 6 connected to the compression spring 61, so that the compression spring 61 is compressed, thereby disengaging the teeth at the other end of the switch device 6 from the slot at the top of the secondary push rod 4.

[0068] like Figure 1 , Figure 5As shown, in the preferred embodiment, a push plate 11 is provided at the head end of the push rod assembly, and the cushioning material is stored in a pair of push plates 11; in this embodiment, the head end of the push rod assembly is defined as the end of the secondary push rod 4 extending out of the primary push rod 2, and the push plate 11 is a structure enclosed by three panel structures, and the cushioning material is placed in the enclosed area.

[0069] In the above solution, the design of the push plate 11 forms an enclosed area, which is used to store the cushioning materials. The existence of the push plate 11 also provides a stable supporting platform for the cushioning materials.

[0070] like Fig.10 As shown, the correct placement of the automatic cushioning tool for steel coil 12 in container 13 is: one end is against the side wall of container 13, and the other end is toward the position of cushioning goods, and cushioning materials 10 such as triangular wood are placed in the push plate 11 of the secondary push rod 4 and keep a certain distance from the steel coil 12.

[0071] like Fig.11 As shown, when the automatic masking tool of the steel coil 12 is in place, the stretching direction is parallel to the radial direction of the steel coil 12, the masking material 10 is tangent to the arc surface of the steel coil 12, and the wedge is put in place.

[0072] The method of using the utility model is as follows:

[0073] Before cushioning: the automatic cushioning tool for the steel coil 12 is in a compressed state and placed on the floor of the container 13. The bottom of its telescopic push rod seat 1 is against a reliable fixed position (for example, the side wall of the container 13). The telescopic direction is parallel to the radial direction of the steel coil 12. The push plate 11 at the other end of the automatic cushioning tool for the steel coil 12 presses against the cushioning material 10, and the cushioning material 10 is placed on the floor of the container 13.

[0074] During padding: personnel remotely control the automatic padding tool of the steel coil 12 from a compressed state to an extended state. During this process, the push plate 11 pushes the padding material 10 to wedge under the arc surface of the steel coil 12 in the easy rolling direction, and the fit is firm.

[0075] End of padding: Manually operate the automatic padding tool of steel coil 12 to compress and change the working position.

[0076] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
