Description

Technical Field

[0001] The utility model relates to the technical field of mechanical assembly, and more specifically, to a lifting auxiliary bracket and a lifting device. Background Art

[0002] During equipment installation and transportation, the use of lifting shackles to hoist large equipment is common. Shackles are frequently used in deepwater lifting and connection operations. However, due to their weight, existing shackle installation methods require manual effort to adjust the shackle's position, align it with the lifting lug, and then insert the pin to complete the installation, making them inconvenient.

[0003] Patent CN217398255U discloses a tool for installing a shackle, comprising: a tool frame, the top of which is provided with a hanging point; a connector, the top of which is connected to the hanging point, and the bottom of which is used to connect the shackle, and the length of the connector is adjustable to adjust the position of the shackle. After the tool for installing the shackle is placed in the installation position, the shackle can be aligned with the lifting ear hole by adjusting the length of the connector, thereby completing the installation of the shackle. The installation process is convenient and fast, and the labor intensity is reduced. In addition, no crane is required, the site requirements are low, and the scope of application is wide. However, in the above scheme, there is no device that can assist in the positioning of the shackle, and the length of the connector needs to be accurately adjusted to align the shackle with the lifting ear hole, which makes the operation difficult and inefficient. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiency of the prior art that it is difficult to accurately position the shackle, and to provide a lifting auxiliary bracket that can conveniently and quickly enable the shackle to reach the specified position.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A lifting auxiliary bracket is provided, comprising a base, a support member and a limit member for limiting the horizontal position of a shackle, wherein the support member is arranged on the base, the limit member is arranged on the support member, and the limit member is provided with a groove for placing the end of the shackle, the opening of the groove faces upward, and the end abuts against the inner wall of the groove.

[0007] The lifting auxiliary bracket of the utility model is fixedly installed on the equipment that needs to be lifted, the shackle is lifted above the groove, and the position of the shackle is adjusted so that the end of the shackle falls into the groove of the limiter. The limiter limits the horizontal position of the end of the shackle. The support member supports the limiter and the end of the shackle and limits the vertical position of the end of the shackle, so that the axial position of the end of the shackle is determined, thereby realizing simple positioning.

[0008] Furthermore, the width of the groove opening is greater than the width of the groove bottom. The groove is a structure that is wide at the top and narrow at the bottom, making it easier for the shackle end to enter the groove, further reducing the difficulty of positioning and improving the positioning efficiency.

[0009] Furthermore, the position-limiting member includes a first side panel, a bottom panel, and a second side panel connected in sequence, the first side panel, the bottom panel, and the second side panel being spliced ​​to form the groove, the first side panel, the bottom panel, and the second side panel all abutting against the outer periphery of the end portion, the angle between the first side panel and the bottom panel being greater than 90° and less than 180°, and / or the angle between the second side panel and the bottom panel being greater than 90° and less than 180°. The angles between the first side panel and the bottom panel, and between the second side panel and the bottom panel, are both obtuse angles, such that the distance between the tops of the first side panel and the second side panel is greater than the length of the bottom panel, making it easier to place the end portion of the shackle into the groove.

[0010] Furthermore, the angle between the first side panel and the bottom panel is greater than 110° and less than 130°, and / or the angle between the second side panel and the bottom panel is greater than 110° and less than 130°. Since the angle between the first side panel or the second side panel and the bottom panel is between 110° and 130°, when the shackle end contacts the first side panel or the second side panel during the falling process, the first side panel or the second side panel will not block the movement of the shackle end, and the component force of the shackle's gravity toward the bottom panel is greater than the resistance encountered by the shackle, making it easier to completely place the shackle end in the groove, making the positioning and installation of the shackle more convenient. At the same time, after the shackle end is placed in the groove, the first side panel and the second side panel can effectively block the horizontal displacement of the shackle end, ensuring the positioning effect.

[0011] Furthermore, the bottom plate is horizontal, and the first and second side plates are symmetrical. The horizontal bottom plate prevents the shackle end from moving horizontally due to gravity. The symmetrical arrangement of the first and second side plates ensures that, during the falling process, the shackle end is just as difficult to enter the groove when it is near the first side plate as when it is near the second side plate, further simplifying the operation.

[0012] Furthermore, the upper surface of the bottom plate is an arc surface that fits the end portion, thereby increasing the resistance of the bottom plate to the end portion of the shackle, and making the positioning of the end portion of the shackle by the limiting member more stable.

[0013] Furthermore, a reinforcement plate is provided between the limiting member and the base, which can improve the structural strength of the auxiliary hoisting bracket, reduce the risk of damage, and extend the service life.

[0014] The utility model also provides a lifting device, including a lifting ear, a connecting piece and the lifting auxiliary bracket as described above, wherein two supporting pieces are provided on the base, two limiting pieces are respectively provided on the two supporting pieces, the lifting ear is provided on the base and is located between the two limiting pieces, the two ends of the shackle are respectively placed on the two limiting pieces, the connecting piece is installed between the two ends and passes through the lifting ear.

[0015] The lifting device of the present invention places the two ends of the lifting ear into the grooves of the two limiting pieces respectively, passes the connecting piece through the lifting ear, and installs the connecting piece on the two ends, thereby installing the lifting ear on the shackle to complete the installation of the lifting device; through the reasonable design of the positional relationship between the limiting piece and the lifting ear, the end of the shackle is located in a suitable installation position when placed in the groove, and there is no need to continue adjusting the position of the shackle, and it can be directly installed, which is simple and efficient to operate.

[0016] Furthermore, the two ends of the shackle are respectively provided with a first mounting hole and a second mounting hole, the lifting ear is provided with a third mounting hole, and the connecting member includes a bolt and a nut. The bolt passes through the first mounting hole, the third mounting hole, and the second mounting hole in sequence and is threadedly connected to the nut. The bolt head of the bolt and the nut both abut against the shackle. The shackle is installed by the cooperation of the bolt and the nut, which has a simple structure, easy operation, and high reliability.

[0017] Furthermore, the axes of the first mounting hole, the second mounting hole, and the third mounting hole are the same. When the two ends of the shackle are placed on the two stoppers, the axes of the first mounting hole, the second mounting hole, and the third mounting hole are the same, so that the bolt will not be obstructed when passing through the shackle and the lifting lug.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The lifting auxiliary bracket and lifting device of the utility model can place the end of the shackle into the groove of the limiter so that the shackle can be placed in a position convenient for connection with the lifting equipment, without the need to further adjust the position of the shackle, and the operation is simple and efficient.

[0027] Example 1

[0028] like Figures 1 to 3 The figure shows a first embodiment of the lifting auxiliary bracket of the present invention, which includes a base 1, a support member 2 and a limit member 3 for limiting the horizontal position of the shackle 6. The support member 2 is arranged on the base 1, and the limit member 3 is arranged on the support member 2. The limit member 3 is provided with a groove 34 for placing the end 61. The opening of the groove 34 faces upward, and the end 61 of the shackle 6 abuts against the inner wall of the groove 34.

[0029] The lifting auxiliary bracket of the present invention is configured to fix the base 1 on the equipment to be lifted, lift the shackle 6 above the groove 34, and adjust the position of the shackle 6 so that the end 61 of the shackle 6 falls into the groove 34 of the limiter 3. The limiter 3 limits the horizontal position of the end 61 of the shackle 6. The support member 2 supports the limiter 3 and the end 61 of the shackle 6 and limits the vertical position of the end 61 of the shackle 6, so that the axial position of the end 61 of the shackle 6 is determined, thereby achieving simple positioning.

[0030] In this embodiment, Figure 2 and Figure 3 As shown, the support member 2 is a plate-like structure. In addition, the support member 2 can also be a block structure, a columnar structure, a bracket structure, etc.

[0031] like Figure 2 As shown, the width of the opening of the groove 34 is greater than the width of the bottom of the groove 34. The groove 34 is a structure that is wide at the top and narrow at the bottom, which makes it easier for the end 61 of the shackle 6 to enter the groove 34, further reducing the difficulty of positioning and improving the positioning efficiency.

[0032] The working principle of the lifting auxiliary bracket in this embodiment is as follows: when performing lifting work, the base 1 is fixedly installed on the equipment to be lifted, the shackle 6 is lifted above the groove 34, the position of the shackle 6 is adjusted, and the end 61 of the shackle 6 is moved above the groove 34 to make the shackle 6 drop. The groove 34 is a structure that is wide at the top and narrow at the bottom, so that the end 61 of the shackle 6 can enter the groove 34 more easily. After the end 61 of the shackle 6 is completely placed in the groove 34, the inner wall of the groove 34 blocks the horizontal movement of the shackle 6, thereby limiting the horizontal position of the shackle 6. The support member 2 supports the limit member 3 and the end 61 of the shackle 6, and limits the vertical position of the end 61 of the shackle 6, so that the axial position of the end 61 of the shackle 6 is determined, and simple positioning is achieved, so that the shackle 6 can be simply installed on the equipment to be lifted.

[0033] Example 2

[0034] This embodiment is the second embodiment of the auxiliary lifting bracket of the utility model. This embodiment is similar to the first embodiment, except that Figure 2 As shown, the stopper 3 includes a first side plate 31, a bottom plate 32, and a second side plate 33 connected in sequence. The first side plate 31, the bottom plate 32, and the second side plate 33 are spliced ​​to form a groove 34. The first side plate 31, the bottom plate 32, and the second side plate 33 all abut against the outer periphery of the end 61. The angle between the first side plate 31 and the bottom plate 32 is greater than 90° and less than 180°, and / or the angle between the second side plate 33 and the bottom plate 32 is greater than 90° and less than 180°. The angles between the first side plate 31 and the bottom plate 32 and the angles between the second side plate 33 and the bottom plate 32 are both obtuse angles, so that the distance between the tops of the first side plate 31 and the second side plate 33 is greater than the length of the bottom plate 32, making it easier to place the end 61 of the shackle 6 into the groove 34.

[0035] Any limiting member 3 that can limit the horizontal position of the end portion 61 of the shackle 6 is applicable to the present invention, and the limiting member 3 listed in this embodiment is not intended to limit the present invention.

[0036] Preferably, in this embodiment, the angle between the first side panel 31 and the bottom panel 32 is greater than 110° and less than 130°, and / or the angle between the second side panel 33 and the bottom panel 32 is greater than 110° and less than 130°. Since the angle between the first side panel 31 or the second side panel 33 and the bottom panel 32 is between 110° and 130°, when the end portion 61 of the shackle 6 contacts the first side panel 31 or the second side panel 33 during the falling process, the first side panel 31 or the second side panel 33 will not block the movement of the end portion 61 of the shackle 6, and the component force of the gravity of the shackle 6 toward the bottom panel 32 is greater than the resistance experienced by the shackle 6, thereby facilitating the complete placement of the end portion 61 of the shackle 6 in the groove 34, making the positioning and installation of the shackle 6 more convenient. At the same time, after the end portion 61 of the shackle 6 is placed in the groove 34, the first side panel 31 and the second side panel 33 can effectively block the horizontal displacement of the end portion 61 of the shackle 6, thereby ensuring the positioning effect.

[0037] Preferably, in this embodiment, the included angle between the first side plate 31 and the bottom plate 32 is 120°, and the included angle between the second side plate 33 and the bottom plate 32 is 120°.

[0038] like Figure 2 As shown, the bottom plate 32 is horizontal, and the first side plate 31 and the second side plate 33 are symmetrical. The horizontal orientation of the bottom plate 32 prevents the end 61 of the shackle 6 from moving horizontally due to gravity. The symmetrical arrangement of the first side plate 31 and the second side plate 33 ensures that, during the falling process, the end 61 of the shackle 6 has the same difficulty entering the groove 34 when it is close to the first side plate 31 as when it is close to the second side plate 33, further simplifying the operation.

[0039] The upper surface of the bottom plate 32 is an arc surface that fits the end portion 61. The resistance of the bottom plate 32 to the end portion 61 of the shackle 6 is increased, so that the positioning of the end portion 61 of the shackle 6 by the stopper 3 is more stable.

[0040] A reinforcement plate 4 is provided between the stopper 3 and the base 1. This plate enhances the structural strength of the auxiliary hoisting bracket, reduces the risk of damage, and extends its service life. The reinforcement plate 4 is fixedly connected to the upper surface of the base 1. The support member 2, first side plate 31, bottom plate 32, and second side plate 33 are also fixedly connected to the reinforcement plate 4.

[0041] The working principle of the lifting auxiliary bracket of this embodiment is as follows:

[0042] When the shackle 6 is lowered, the first side plate 31 or the second side plate 33 is in contact with the first side plate 31 or the second side plate 33. When the shackle 6 is lowered, the first side plate 31 or the second side plate 33 is in contact with the first side plate 31 or the second side plate 33. The first side plate 31 or the second side plate 33 will not block the movement of the shackle 6 end 61 and make the component force of the shackle 6 toward the bottom plate 32 greater than the resistance of the shackle 6. It is convenient to completely put the end 61 of the shackle 6 into the groove 34, making the positioning and installation of the shackle 6 more convenient. At the same time, after the end 61 of the shackle 6 is completely put into the groove 34, the first side plate 31 and the second side plate 33 can effectively block the horizontal displacement of the end 61 of the shackle 6, thereby ensuring the positioning effect.

[0043] Example 3

Figure 3 and Figure 4 As shown, the connecting piece 7 is mounted between the two ends 61 and passes through the lifting lug 5 .

[0045] The lifting device of the present invention places the two end portions 61 of the lifting ear 5 into the grooves 34 of the two limiting members 3 respectively, passes the connecting member 7 through the lifting ear 5, and installs the connecting member 7 on the two end portions 61, thereby installing the lifting ear 5 on the shackle 6 to complete the installation of the lifting device; through the reasonable design of the positional relationship between the limiting member 3 and the lifting ear 5, the end portion 61 of the shackle 6 is located in a suitable installation position when placed in the groove 34, and there is no need to continue adjusting the position of the shackle 6, and it can be directly installed, which is simple and efficient to operate.

[0046] The two ends 61 of the shackle 6 are respectively provided with a first mounting hole 62 and a second mounting hole 51, and the lifting ear 5 is provided with a third mounting hole 63. The connecting member 7 includes a bolt 71 and a nut 72. The bolt 71 passes through the first mounting hole 62, the third mounting hole 63, and the second mounting hole 51 in sequence and is threadedly connected with the nut 72. The bolt head 71 of the bolt 71 and the nut 72 both abut against the shackle 6. The shackle 6 is installed by the cooperation of the bolt 71 and the nut 72, which has a simple structure, easy operation, and high reliability.

[0047] The axes of the first mounting hole 62, the second mounting hole 51, and the third mounting hole 63 are aligned. When the two ends 61 of the shackle 6 are placed on the two stoppers 3, the axes of the first mounting hole 62, the second mounting hole 51, and the third mounting hole 63 are aligned, so that the bolt 71 will not be obstructed when passing through the shackle 6 and the lifting lug 5.

[0048] The working principle of the lifting device of this embodiment is as follows: after the two end portions 61 of the lifting ear 5 are respectively placed in the grooves 34 of the two limiting members 3, the positioning is completed. At this time, the axes of the first mounting hole 62, the third mounting hole 63 and the second mounting hole 51 are the same, and there is no need to continue to adjust the position of the shackle 6. The bolt 71 is passed through the first mounting hole 62, the third mounting hole 63 and the second mounting hole 51 in sequence, and the nut 72 is put on the bolt 71. The nut 72 is rotated to move the nut 72 toward the second mounting hole 51 until the nut 72 and the bolt 71 head tighten the shackle 6, completing the fixed connection between the shackle 6 and the lifting ear 5, and the lifting operation can be carried out.
