[0001] The utility model relates to the technical field of lifting clamp manufacturing, in particular to an integrated double-suspension lifting sling. Background Art

[0002] The current lifting equipment cannot simultaneously meet the requirements of hooking and lifting the base and the container on the base, as well as the supporting equipment or items stacked or piled like the base and the container. For example, when lifting molten liquid, the molten liquid is usually stored in a container (furnace). When the container loaded with molten liquid is placed on the ground, the base needs to be placed on the ground, and the container is placed on the base. When the container is transported by a crane (hoisting device), the container and the base need to be transported in turn, that is, the current clamp cannot meet the requirements of clamping the container and the base at the same time, and the container and the base need to be clamped separately each time, which is inefficient.

[0003] Prior art 1: CN206142657U discloses a connecting rod clamp, including a pair of clamping arms, a fixed sleeve, a pull rod and a connecting rod mechanism, wherein the connecting rod mechanism includes a pair of movable connecting rods and a pair of connecting rod arms, the pull rod is arranged in the fixed sleeve, one end of the pair of movable connecting rods is hinged on the pull rod, the other end of the pair of movable connecting rods is respectively hinged to one end of a pair of connecting rod arms, the pair of connecting rod arms are hinged on the fixed sleeve, and the pair of clamping arms are respectively arranged on the other end of the pair of connecting rod arms.

[0004] The prior art discloses a lifting device that, under the action of articulation, pulls the strap and the rod to clamp the material. That is, the prior art only discloses the clamping of one material (container), and cannot solve the problem of lifting the base and the container and similar equipment or items at the same time. In actual production applications, there are problems such as back and forth lifting, wasting time, complex management, and low efficiency. Utility Model Content

[0005] The technical problem solved by the utility model is to overcome the defects in the prior art and provide an integrated double-lifting hoisting device which can clamp and lift a base and a container at the same time.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] Disclosed is an integrated double-lift lifting sling, which includes a connecting seat connected to a crane, a base clamp arranged on the connecting seat for hooking a base, and a container clamp arranged on the connecting seat for clamping a container, wherein the container clamp includes a top seat connected to the connecting seat, a first connecting rod and a second connecting rod hinged to the top seat, a first L-shaped connecting rod hingedly connected to an end of the first connecting rod away from the top seat, and a second L-shaped connecting rod hingedly connected to an end of the second connecting rod away from the top seat; clamping blocks for clamping an outer wall of a container are respectively connected to the movable ends of the first L-shaped connecting rod and the second L-shaped connecting rod; the container clamp also includes a base hinged to the first L-shaped connecting rod and the second L-shaped connecting rod, and a locking mechanism for locking the opening angle of the container clamp is further provided between the base and the top seat.

[0008] Preferably, the top seat and the connecting seat are connected by bolts.

[0009] Preferably, the base fixture comprises a slide rail and an electric push rod arranged on a connecting seat, a slider matched with the slide rail, and a hook connected with the slider, wherein the slide rail is connected to the telescopic end of the electric push rod.

[0010] Preferably, the base clamps are arranged at the four corners of the bottom of the connecting base.

[0011] Preferably, a pulley cooperating with a winch on a crane is provided on the top of the connecting seat.

[0012] Preferably, the clamping block is also provided with a pad to increase the friction between the clamping block and the outer wall of the container.

[0013] Preferably, the container clamp further comprises a synchronization rod for controlling the synchronous movement of the first L-shaped connecting rod and the second L-shaped connecting rod, and two ends of the synchronization rod are respectively hinged to the first L-shaped connecting rod and the second L-shaped connecting rod.

[0014] Preferably, the locking mechanism is a square hole hook seat.

[0015] Preferably, a column is also provided on the base, and the locking mechanism is connected to the column.

[0016] Preferably, the base is also provided with a limiting column for fixing the container.

[0017] The utility model of the sling, by changing the existing sling structure, simultaneously sets the base clamp and the container clamp on the connecting seat, so that the base and the container, or the supporting equipment or articles stacked together similar to the base and the container, can be hooked at the same time. The overall structure of the sling is compact, and the base clamp is used to clamp the base, and the container clamp is used to clamp the container. It can realize both simultaneous clamping and separate clamping, and can be implemented simultaneously without interfering with each other.

[0018] The base clamp and container clamp of the utility model can also be used separately, and any one of the supporting equipment can be lifted separately each time, for example, the base can be lifted separately, or the container can be lifted separately. In view of the change of working conditions such as simultaneous lifting or separate lifting, the utility model does not need to change the structure of the lifting device, which is very flexible. Compared with the prior art, the present application has the following beneficial effects:

[0019] 1) The present application is cleverly designed. The container clamp and the base clamp are arranged on the connecting seat, which can not only meet the needs of lifting the base or container separately, but also meet the needs of lifting the container and the base at the same time. The base and the container and similar stacked or piled supporting equipment can be hooked and lifted at the same time without changing the key main structure of the crane. The structure is compact and the efficiency is significantly improved.

[0020] 2) The opening angle of the container clamp is further locked by a locking mechanism, thereby ensuring that the container clamp can always be in an open state in an empty state, thereby further improving the clamping efficiency of the container.

[0021] 3) A column is further arranged on the base, and the locking mechanism is connected to the column, so that the opening angle of the container clamp is controlled by the column. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1

[0031] like Figures 1 to 3As shown, an integrated double-lifting lifting sling is disclosed, which includes a connecting seat 1 connected to a crane, a base clamp 2 arranged on the connecting seat 1 for hooking a base, and a container clamp 3 arranged on the connecting seat 1 for clamping a container, wherein the container clamp 3 includes a top seat 30 fixedly connected to the connecting seat, a first connecting rod 31 and a second connecting rod 32 hinged to the top seat 30, a first L-shaped connecting rod 33 hingedly connected to an end of the first connecting rod 31 away from the top seat 30, and a second L-shaped connecting rod 34 hingedly connected to an end of the second connecting rod 32 away from the top seat 30; clamping blocks 35 for clamping an outer wall of a container are respectively connected to the movable ends of the first L-shaped connecting rod 33 and the second L-shaped connecting rod 34; the container clamp 3 also includes a base 36 hingedly connected to the first L-shaped connecting rod 33 and the second L-shaped connecting rod 34, and a locking mechanism 37 for locking the opening angle of the container clamp is also arranged between the base 36 and the top seat 30.

[0032] In this embodiment, the integrated double-lift hoisting device includes a connecting seat 1, which is connected to the crane through a steel wire rope, and can be specifically connected to a winch on the crane. A base clamp 2 and a container clamp 3 are arranged on the connecting seat 1, and the base is clamped by the base clamp 2, and the container clamp 3 is used to clamp the container.

[0033] The base clamp 2 and the container clamp 3 are cleverly arranged on the connecting seat 1 at the same time, so that simultaneous clamping can be achieved while orderly clamping can also be achieved, that is, any one of the supporting equipment can be lifted separately each time, for example, the base can be lifted separately, or the container can be lifted separately. The base and the container and similar stacked or piled supporting equipment can be hooked and lifted at the same time without changing the key main structure of the crane. The structure is compact and the efficiency is significantly improved. The base is clamped by the base clamp 1 and the container is clamped by the container clamp 3, which can be implemented simultaneously without interfering with each other. When the crane lifts the connecting seat, under the action of the hinge, the clamp block 35 will gradually approach the outer wall of the container, thereby clamping the container. Compared with only lifting one of the base or the container at a time, the lifting efficiency of the crane is improved. It also avoids the crane from lifting back and forth, which has an energy-saving effect.

[0034] The container clamp 3 includes a top seat 30 fixedly connected to the connecting seat 1, which can be connected by bolts. A first connecting rod 31 and a second connecting rod 32, a first L-shaped connecting rod 33, and a second L-shaped connecting rod 44 are hinged to the top seat 30; the end of the first connecting rod 31 away from the top seat 30 is hinged to the first L-shaped connecting rod 33, and the end of the second connecting rod 32 away from the top seat 30 is hinged to the second L-shaped connecting rod 34; the movable ends of the first L-shaped connecting rod 33 and the second L-shaped connecting rod 34 are respectively connected with clamping blocks 35 for clamping the outer wall of the container; the first L-shaped connecting rod 33 and the second L-shaped connecting rod 34 are hinged to the base 36, such as. The first L-shaped connecting rod 33 and the second L-shaped connecting rod 34 are connected to the base 36 through a pin shaft. Under the action of the hinge, as the crane rises, the two clamping blocks 35 will gradually move closer until they are close to the outer wall of the container. Under the action of friction and clamping force, the two clamping blocks 35 will tightly clamp the container, thereby clamping the container.

[0035] Example 2

[0036] Disclosed is an integrated double-lifting lifting sling, which includes a connecting seat 1 connected to a crane, a base clamp 2 arranged on the connecting seat 1 for hooking a base, and a container clamp 3 arranged on the connecting seat 1 for clamping a container, wherein the container clamp 3 includes a top seat 30 fixedly connected to the connecting seat, a first connecting rod 31 and a second connecting rod 32 hinged to the top seat 30, a first L-shaped connecting rod 33 hingedly connected to an end of the first connecting rod 31 away from the top seat 30, and a second L-shaped connecting rod 34 hingedly connected to an end of the second connecting rod 32 away from the top seat 30; clamping blocks 35 for clamping an outer wall of a container are respectively connected to the movable ends of the first L-shaped connecting rod 33 and the second L-shaped connecting rod 34; the container clamp 3 also includes a base 36 connected to the first L-shaped connecting rod 33 and the second L-shaped connecting rod 34, and a locking mechanism 37 for locking the opening angle of the container clamp is also arranged between the base 36 and the top seat 30.

[0037] The difference between this embodiment and embodiment 1 is that in order to improve the clamping stability of the container, a pad is further provided on the clamp block 35 to increase the friction between the clamp block 35 and the outer wall of the container, and the pad is provided on the surface where the clamp block 35 clamps the container.

[0038] In order to prevent the clamp block 35 from not opening properly or opening slowly, thereby affecting the speed of the clamp block clamping the container, a locking mechanism 37 is provided on the container clamp to lock the opening angle (that is, the open state) of the container clamp, one end of the locking mechanism 37 is fixedly connected to the top seat 30, and the other end is connected to the base 36. After the crane hoists the container to the designated position, the winch continues to lower, and the clamp block 35 gradually moves away from the outer wall of the container, so that the container clamp is in a fully open state. At this time, the state of the container clamp is locked by the locking mechanism, so that the container clamp is always in an open state before the next container is grabbed.

[0039] The locking mechanism 37 may be a square hole hook seat. Specifically, a column may be provided on the base 36, and one end of the locking mechanism 37 is connected to the column. The height of the locking mechanism 37 remains unchanged, and the column is added to change the distance between the base 36 and the top seat 30, thereby adjusting the opening state of the container clamp. Changing the height of the column can change the maximum opening state of the container clamp.

[0040] The square hole lock seat is an existing product in the industry, and its specific structural description is omitted here.

[0043] The difference between this embodiment and embodiment 1 is that the base fixture 2 includes a slide rail arranged on the connection seat 1, a slider adapted to the slide rail, an electric push rod arranged on the connection seat 1, and a hook connected to the slider, and the slide rail is connected to the telescopic end of the electric push rod. The base is hooked by the hook, thereby achieving hooking of the base. The hook is fixed on the slider, the slider moves under the action of the electric push rod, and the hook moves with the slider, thereby achieving hooking or unhooking of the base.

[0044] In this embodiment, the driving force of the slider is provided by an electric push rod, and may also be replaced by a type of driving device, such as a telescopic cylinder.

[0045] Specifically, four base clamps 2 can be provided, distributed at the four corners of the bottom of the connecting base 1. Four groups of base clamps 2 hook the base, ensuring the connection stability between the base clamps 2 and the base.

[0048] The difference between this embodiment and embodiment 1 is that in order to facilitate the connection between the clamp and the crane, a pulley 4 that cooperates with the hoist on the crane can be set on the top of the connecting seat. The pulley 4 is a conventional technology in the industry and will not be described in detail here.

[0049] In order to improve the hooking accuracy of the integrated double-lifting lifting device and prevent the container from sliding, a limiting column for limiting the container can also be set on the base. The limiting column can specifically include four, and when the container is placed on the base, the container is just between the four limiting columns.
