Description

Technical Field

[0001] The invention relates to the technical field of hanging elements, in particular to a hanging element for transporting a large-scale cover mold. Background Art

[0002] In the process of transporting large cover molds, lifting equipment is indispensable, among which the hanging assembly is an important part of the lifting equipment. The hanging element is a device used to hang, support or connect objects. Common hanging elements include hooks and rings. The hook can hang heavy objects, and the ring can connect to the sling or hook, so as to realize the lifting and transportation of large cover molds.

[0003] However, with regard to the existing hanging elements for the transportation of large cover molds, the baffle rod used to close the gap to prevent the lifting ring from falling out relies on manual operation to control its usage status. That is, each time the hook is connected to the lifting ring on the mold body, it is necessary to manually pry the baffle rod for operation, which is rather cumbersome. This design defect is particularly prominent in the scenario of multi-hanging point collaborative operation, because large cover molds are generally equipped with multiple sets of hooks and lifting rings for use during lifting. The installation and removal of multiple sets of hooks and lifting rings are inefficient, less flexible, and not very practical. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a hanging element for transporting a large cover mold to solve the problems mentioned in the above background technology.

[0005] The present invention provides a hanging element for the transfer of large-scale cover parts molds, specifically comprising: a hanging component and an adaptive component; the hanging component comprises a transfer hook, a lifting column and a locking block, the transfer hook and the locking block are both designed with a "U"-shaped cross-section, and the transfer hook is connected to the lifting equipment through a wire rope, the lifting column is inserted at the top of the transfer hook, and the locking block is inserted inside the transfer hook; the adaptive component comprises a safety barrier rod, a linkage gear and an adaptive block, the safety barrier rod is rotatably connected to the top side of the transfer hook, the linkage gear is rotatably connected to the outside of the rotating shaft of the safety barrier rod, and the linkage gear is rotatably connected to the inside of the transfer hook, and the adaptive block is inserted inside the rotating shaft of the safety barrier rod along the radial direction of the rotating shaft of the safety barrier rod.

[0006] Furthermore, a no-load tension spring is provided inside the lifting column, and two ends of the no-load tension spring are respectively fixedly connected to the bottom of the lifting column and the inside of the transfer hook.

[0007] Furthermore, a linkage rack is provided on the side of the lifting column, and the linkage rack can mesh with the teeth of the linkage gear when following the movement of the lifting column.

[0008] Furthermore, an opening torsion spring is provided outside the rotating shaft of the safety barrier rod, and two ends of the opening torsion spring are respectively fixedly connected inside the rotating shaft of the safety barrier rod and inside the transfer hook.

[0009] Furthermore, an adaptive top spring is provided at the bottom of the adaptive block, and two ends of the adaptive top spring are respectively fixedly connected to the top of the adaptive block and the inside of the transfer hook.

[0010] Furthermore, an adaptive tooth groove is provided inside the linkage gear, and the cross-section of the outer block of the adaptive block and the cross-section of a single tooth groove of the adaptive tooth groove are both right-angled triangles.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The hanging assembly can be used in conjunction with the lifting ring on the large cover mold to meet the use needs of the large cover mold transfer. The operation is convenient and flexible, and the adaptive assembly can automatically control the use status of the safety lever according to the actual load of the hanging assembly, that is, when the hanging assembly is in a load lifting state, the safety lever can automatically seal the notch of the transfer hook to avoid the phenomenon of the lifting ring falling off the transfer hook during the lifting process. The lifting is safe and stable. When the hanging assembly is in an unloaded state, the safety lever can automatically switch to a horizontal state for use, and open the notch of the transfer hook to facilitate the installation and removal operations between the transfer hook and the lifting ring, thereby simplifying the operating process and improving the transfer efficiency of large cover molds.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 10 as shown in Embodiment 1: The present invention provides a hanging element for transporting a large covering die, including a hanging assembly 1 and an adaptive assembly 2; the hanging assembly 1 includes a transport hook 101, a lifting column 102 and a locking block 103. Both the transport hook 101 and the locking block 103 are designed with a "U"-shaped cross-section. The transport hook 101 is connected to a hoisting device through a steel wire rope. The lifting column 102 is inserted into the top of the transport hook 101, and the locking block 103 is inserted into the interior of the transport hook 101; the adaptive assembly 2 includes a safety stop bar 201, a linkage gear 202 and an adaptor block 203. The safety stop bar 201 is rotatably connected to the side of the top of the transport hook 101. The linkage gear 202 is rotatably connected to the outside of the rotating shaft of the safety stop bar 201 and is also rotatably connected to the interior of the transport hook 101. The adaptor block 203 is inserted into the interior of the rotating shaft of the safety stop bar 201 along the radial direction of the rotating shaft of the safety stop bar 201.

[0031] Among them, an idle-load spring 1021 is provided inside the lifting column 102, and both ends of the idle-load spring 1021 are fixedly connected to the bottom of the lifting column 102 and the interior of the transport hook 101 respectively. During use, when the hanging assembly 1 is in an idle-load state, the safety stop bar 201 is used in a horizontal state, thus opening the notch part of the transport hook 101 to facilitate the installation and removal operation between the transport hook 101 and the lifting ring. It can be done by directly inserting the transport hook 101 into the interior of the lifting ring. When the hanging assembly 1 is in an idle-load state, under the action of the idle-load spring 1021, the lifting column 102 is at the lowest position inside the transport hook 101, and the lifting column 102 can press against the contact ring 1032 in such a way that the locking stop block 1033 will not block the safety stop bar 201. Thus, under the action of the opening torsion spring 2011, the safety stop bar 201 is used in a horizontal state and will not block the notch position of the transport hook 101, thus facilitating the cooperation between the transport hook 101 and the lifting ring.

[0032] Among them, a linkage rack 1022 is provided on the side of the lifting column 102, and the linkage rack 1022 can mesh with the gear teeth of the linkage gear 202 when following the movement of the lifting column 102. When the lifting column 102 is located at the top and bottom of the transfer hook 101, the linkage rack 1022 will not mesh with the gear teeth of the linkage gear 202. In use, when the hanging assembly 1 is in lifting, the load acting on the transfer hook 101 increases, and the safety barrier rod 201 can automatically block the notch of the transfer hook 101, and the safety barrier rod 201 will lock the current use state to avoid the phenomenon that the lifting ring falls off the transfer hook 101 during lifting. When lifting a large cover mold, the lifting equipment drives the lifting column through a wire rope. 102 moves upward. Since the transfer hook 101 is blocked by the lifting ring of the large cover mold at this time, the transfer hook 101 cannot follow the lifting column 102 to move upward in the initial stage of lifting. At this time, when the lifting column 102 moves upward alone, the no-load tension spring 1021 will be lengthened, and in this process, the linkage rack 1022 can drive the linkage gear 202 to rotate counterclockwise. When the linkage gear 202 rotates counterclockwise, the adaptation tooth groove 2021 and the straight edge of the adaptation block 203 are engaged to drive the safety stop bar 201 to rotate downward until the safety stop bar 201 is in a vertical state. A resistance ring 1032 is provided on the top of the locking block 103, and the resistance ring 1032 is located directly below the lifting column 102, and the spring body of the no-load tension spring 1021 passes through the inner part of the resistance ring 1032. The lifting column 102 is in the upward movement, and the lifting column 102 has no resistance and squeeze effect on the friction ring 1032. The top of the locking block 103 is provided with a locking tension spring 1031, and the two ends of the locking tension spring 1031 are respectively fixedly connected to the top of the locking block 103 and the inside of the transfer hook 101. The bottom of the locking block 103 is provided with a locking stopper 1033 with a right triangle cross section, and the inside of the safety barrier rod 201 is provided with a locking stopper groove 2012. When the safety barrier rod 201 is used vertically and the friction ring 1032 is not subject to external force, the locking stopper 1033 passes through the locking stopper groove 2012, and the straight edge of the locking stopper 1033 is clamped on the side of the safety barrier rod 201. 03 will move up, and when the safety stop rod 201 rotates to the position of the locking stop block 1033, the locking stop groove 2012 can squeeze and resist the locking stop block 1033 to make it move downward, so that the locking stop groove 2012 can pass through the locking stop block 1033. After passing through the locking stop groove 2012, the locking stop block 1033 will jam the rod body of the safety stop rod 201 under the action of the locking tension spring 1031 so that it will not reset, and lock the safety stop rod 201 to the blocking state of the gap of the transfer hook 101. After that, the lifting column 102 is at the top of the transfer hook 101, and the lifting column 102 is rigidly resisted with the transfer hook 101, thereby driving the hanging assembly 1 to lift the large cover mold for transportation and use, and the lifting is safe and stable.

[0033] Among them, an opening torsion spring 2011 is provided on the outside of the rotating shaft of the safety stopper rod 201, and the two ends of the opening torsion spring 2011 are respectively fixedly connected to the inside of the rotating shaft of the safety stopper rod 201 and the inside of the transfer hook 101. In use, when the large cover mold is lifted to a suitable position and landed, the load on the hanging assembly 1 will disappear, and the elastic force of the no-load tension spring 1021 is greater than the elastic force of the locking tension spring 1031. Therefore, under the action of the no-load tension spring 1021, the lifting column 102 will move downward inside the transfer hook 101 and drive the locking block 103 to move downward again by squeezing the resistance ring 1032. When the locking block 103 moves downward, the locking block 1033 will release the blocking and locking effect on the safety stopper rod 201. Thereafter, under the action of the opening torsion spring 2011, the safety stopper rod 201 will automatically rotate upward to return to a horizontal state, and the notched part of the transfer hook 101 will be opened again to facilitate disassembly or re-installation with the remaining lifting rings. It is flexible and convenient to use.

[0034] Among them, an adaptable top spring 2031 is provided at the bottom of the adaptable block 203, and the two ends of the adaptable top spring 2031 are respectively fixedly connected to the top of the adaptable block 203 and the inside of the transfer hook 101, and an adaptable tooth groove 2021 is provided inside the linkage gear 202, and the cross-section of the outer block of the adaptable block 203 and the cross-section of a single tooth groove of the adaptable tooth groove 2021 are both right-angled triangles. Under the action of the adaptable top spring 2031, the block part of the right-angled triangle cross-section of the adaptable block 203 is inserted into the inside of the adaptable tooth groove 2021, and when the linkage gear 202 rotates counterclockwise, the adaptable block 203 and the groove body straight edge of the adaptable tooth groove 2021 are clamped. In use, after the large cover mold is lifted to a suitable position and landed, the safety barrier rod 201 is automatically switched to a horizontal state for use. At the initial stage of the downward movement of the lifting column 102, the linkage gear Although bar 1022 will drive the linkage gear 202 to rotate clockwise, when the linkage gear 202 rotates clockwise, the oblique edges of the adapting tooth groove 2021 and the oblique edges of the adapting block 203 will collide and squeeze each other, causing the adapting block 203 to move toward the inside of the rotating shaft of the safety stop bar 201 to avoid the clockwise rotation of the linkage gear 202, and will compress the adapting top spring 2031, so that the device will not get stuck. When the lifting column 102 moves to the bottom of the transfer hook 101, the linkage gear 202 and the linkage rack 1022 have already lost the gear tooth meshing relationship. Thereafter, when the safety stop bar 201 rotates upward, the adapting block 203 can drive the linkage gear 202 to actively rotate clockwise under the clamping action of the straight edge of the adapting tooth groove 2021, so that the device will not get stuck, and it is smooth and flexible to use.

[0035] Specific usage method and function of this embodiment: In the present invention, by using the hanging component 1 in cooperation with the lifting ring on the large panel die, the operation of lifting and transporting the large panel die can be achieved. When the hanging component 1 is in the no-load state, the safety stop bar 201 is used in the horizontal state, thus opening the notch part of the transfer hook 101, which facilitates the installation and removal operation between the transfer hook 101 and the lifting ring. It can be directly inserted into the lifting ring. When the hanging component 1 is in the no-load state, under the action of the no-load tension spring 1021, the lifting column 102 is at the lowest position inside the transfer hook 101, and the lifting column 102 can squeeze the contact ring 1032, so that the locking block 1033 will not block the safety stop bar 201. Thus, under the action of the opening torsion spring 2011, the safety stop bar 201 is used in the horizontal state and will not block the notch position of the transfer hook 101, which facilitates the cooperation between the transfer hook 101 and the lifting ring. When the hanging component 1 is in hoisting, at this time, the load acting on the transfer hook 101 increases, and the safety stop bar 201 can automatically block the notch part of the transfer hook 101, and the safety stop bar 201 will lock the current usage state to avoid the phenomenon that the lifting ring disengages from the transfer hook 101 during hoisting. When hoisting the large panel die, the hoisting equipment drives the lifting column 102 to move upward through the steel wire rope. Since the transfer hook 101 is blocked by the lifting ring of the large panel die at this time, the transfer hook 101 cannot move upward with the lifting column 102 at the initial stage of hoisting. At this time, when the lifting column 102 moves upward alone, it will stretch the no-load tension spring 1021. And during this process, the linkage rack 1022 can drive the linkage gear 202 to rotate counterclockwise. When the linkage gear 202 rotates counterclockwise, the adaptation tooth groove 2021 engages with the straight edge of the block body of the adaptation block 203 to drive the safety stop bar 201 to rotate downward until the safety stop bar 201 is in the vertical state. And due to the upward movement of the lifting column 102, the contact and extrusion effect of the lifting column 102 on the contact ring 1032 disappears. Thus, under the action of the locking tension spring 1031, the locking block 103 will move upward. When the safety stop bar 201 rotates to the position of the locking block 1033, the locking groove 2012 can squeeze and contact the locking block 1033 to make it move downward, so that the locking groove 2012 can pass through the locking block 1033. After the locking block 1033 passes through the locking groove 2012, under the action of the locking tension spring 1031, the locking block 1033 will block the rod body of the safety stop bar 201 so that it will not reset, locking the blocking state of the safety stop bar 201 on the notch of the transfer hook 101. After that, the lifting column 102 is at the topmost part inside the transfer hook 101, and the lifting column 102 is rigidly connected to the transfer hook 101 in contact, thereby driving the hanging component 1 to lift and transport the large panel die. When the large panel die is hoisted to the appropriate position and lands, at this time, the load on the hanging component 1 will disappear. Thus, under the action of the no-load tension spring 1021,The lifting column 102 will move downward inside the transfer hook 101 and drive the locking block 103 to move downward again by squeezing the resistance ring 1032. When the locking block 103 moves downward, the locking block 1033 will release the blocking and locking effect on the safety baffle 201, so that under the action of the opening torsion spring 2011, the safety baffle 201 will automatically rotate upward to restore to a horizontal state, and the notched part of the transfer hook 101 will be opened again to facilitate disassembly or re-installation with other lifting rings. After the large cover mold is lifted to a suitable position and landed, the safety baffle 201 will automatically switch to a horizontal state for use. In the process of the lifting column 102 moving downward at the initial stage, the linkage rack 1022 will drive the linkage gear 202 clockwise. The needle rotates, but when the linkage gear 202 rotates clockwise, the slot bevel of the adapting tooth groove 2021 and the block bevel of the adapting block 203 will collide and squeeze each other, so that the adapting block 203 moves toward the inside of the rotating shaft of the safety stop bar 201 to avoid the clockwise rotation of the linkage gear 202, and compresses the adapting top spring 2031, so that the device will not be stuck. When the lifting column 102 moves to the bottom of the transfer hook 101, the linkage gear 202 and the linkage rack 1022 have already lost the gear meshing relationship. Therefore, when the safety stop bar 201 rotates upward, the adapting block 203 can drive the linkage gear 202 to actively rotate clockwise under the action of the straight edge of the tooth groove of the adapting tooth groove 2021, so that the device will not be stuck.
