Technical Field

[0001] The invention relates to the field of hoisting construction, in particular to a hoisting tool. Background Art

[0002] Marine storage tanks are containers installed on ships for storing liquid cargoes. To ensure the long-term stable operation of the tanks and prevent cargo contamination, the inner wall of the marine storage tanks is usually protected by a film maintenance system so that the inner wall of the tank has a good insulation effect and a certain pressure resistance.

[0003] The film maintenance system usually includes plywood, metal film and polyurethane foam. During the installation process, the film maintenance system usually needs to be built layer by layer on the inner wall of the tank. When the tank is large, the plywood located on the side wall of the tank needs to be lifted to the designated position on the inner wall of the tank by the cooperation of lifting equipment and lifting tools.

[0004] The lifting tooling used for lifting plywood usually includes two clamping parts and a moving assembly driving the two clamping parts to move toward each other. After the two clamping parts clamp the plywood by moving toward each other and lift it to a designated position, it is usually necessary for workers to perform auxiliary flipping and positioning to achieve stable installation of the plywood, and the work efficiency during the plywood installation is low. Summary of the invention

[0005] In order to facilitate the rapid installation of plywood to a designated installation position and improve the work efficiency during the installation of the plywood, the present application provides a lifting tool.

[0006] The present application provides a lifting tool that adopts the following technical solution: A lifting tool comprises a lifting fixed seat, a lifting installation seat, a lifting clamping mechanism and a lifting rotating mechanism. The lifting clamping mechanism is arranged on the lifting installation seat and is used to clamp and fix the workpiece. The lifting rotating mechanism comprises a first rotating component and a second rotating component. The first rotating component and the second rotating component are both arranged on the lifting fixed seat and are respectively used to drive the lifting installation seat to rotate around the x-axis and the z-axis.

[0007] By adopting the above technical solution, when installing the plywood, the workpiece, i.e., the plywood, is first clamped and fixed by the hoisting clamping mechanism, and then the hoisting fixing seat is hoisted. When the plywood is close to the designated installation position, the hoisting mounting seat is driven to rotate by the first rotating assembly and the second rotating assembly so that the plywood can be quickly flipped to the designated installation position in the storage tank without the need for auxiliary flipping by the staff, thereby helping to improve the efficiency of plywood installation.

[0008] Optionally, the first rotating assembly includes a first motor, a first rotating gear, a main driving gear, a main bevel gear and a slave bevel gear, the first rotating gear is rotatably mounted on a lifting and fixing seat, the first motor is used to drive the first rotating gear to rotate, the main driving gear is rotatably mounted on the lifting and fixing seat and meshes with the first rotating gear, the main bevel gear is coaxially fixedly mounted on the main driving gear, the lifting and fixing seat has a horizontally arranged mounting shaft, the mounting shaft is rotatably matched with the lifting and fixing seat, and the slave bevel gear is coaxially fixedly mounted on the mounting shaft and meshes with the main bevel gear.

[0009] By adopting the above technical solution, when the first motor drives the first rotating gear to rotate, the main driving gear drives the main bevel gear to rotate together, and the slave bevel gear drives the installation shaft and the lifting fixing seat to rotate around the x-axis together, so that it is convenient to flip the plywood after the workpiece, i.e. the plywood, is clamped and fixed, and then the plywood can be quickly rotated to the desired installation position.

[0011] By adopting the above technical solution, when the second motor drives the second rotating gear to rotate, the second driving gear rotates together due to the meshing with the second rotating gear, and the transmission shaft drives the installation shaft and the lifting mounting seat to rotate together, thereby realizing the rotation of the lifting mounting seat around the x-axis and the z-axis, and then facilitating the faster and more stable rotation of the plywood to the desired installation position by flipping and rotating the plywood horizontally after the workpiece, i.e., the plywood, is clamped and fixed. The first rotating assembly and the second rotating assembly have a high degree of integration, which is convenient for use in limited space.

[0012] Optionally, the first rotating assembly further includes a first reinforced gear, and the second rotating assembly further includes a second reinforced gear, the first reinforced gear being coaxially mounted on the output shaft of the second motor and meshing with the main drive gear, and the second reinforced gear being coaxially mounted on the output shaft of the first motor and meshing with the second drive gear.

[0014] Optionally, the hoisting fixed device is provided with a protective cover for covering the first rotating gear, the main driving gear, the second rotating gear and the second driving gear.

[0015] By adopting the above technical solution, the protective cover plays a protective role for each gear during transmission, so that external components are not likely to affect the transmission of each gear, which makes it easy to ensure the stability of the transmission of each gear.

[0016] Optionally, the hoisting clamping mechanism includes a clamping seat and a clamping motion assembly, two clamping seats are arranged opposite each other, and both of the clamping seats are slidably fitted on the bottom of the hoisting mounting seat; the clamping motion assembly includes a clamping telescopic cylinder, a clamping drive rod and a clamping connecting rod, and two clamping connecting rods are arranged, the clamping drive rod is rotatably installed on the hoisting mounting seat, one end of the two clamping connecting rods is rotatably installed on the clamping drive rod and respectively close to the two ends of the clamping drive rod in the length direction, and the other ends of the two clamping connecting rods are respectively rotatably installed on the two clamping seats, and the clamping telescopic cylinder is used to drive one of the clamping seats to move toward or away from the other clamping seat.

[0017] By adopting the above technical solution, when the clamping telescopic cylinder drives one of the clamping seats to move towards or away from the other clamping seat, one of the clamping links drives the other clamping seat to move synchronously through the clamping drive rod and the other clamping link, thereby facilitating the rapid movement of the two clamping seats towards or away from each other, and further facilitating the rapid clamping and fixing or loosening of the workpiece, i.e., the plywood, through the two clamping seats.

[0018] Optionally, the hoisting mounting seat is fixedly mounted with a horizontally arranged clamping guide rail, and two groups of the clamping guide rails are arranged corresponding to the clamping seat, and the two groups of the clamping guide rails are respectively passed through and slidably matched with the two clamping seats.

[0019] By adopting the above technical solution, the clamping guide rail plays a further limiting role when the clamping seat slides, which is beneficial to further ensure the stability of the two clamping seats when they move towards or away from each other.

The arrangement of the clamping parts facilitates multi-point clamping of the workpiece, provides a more uniform clamping force, and thus makes the workpiece less likely to deform during the clamping process.

[0022] Optionally, each of the clamping parts is inserted into the clamping and fixing part and slidably cooperates with the clamping and fixing part, and each of the clamping parts is tightly fixed to the clamping and fixing part by bolts.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the plywood is close to the designated installation position, the first rotating assembly and the second rotating assembly drive the rotation of the hoisting mounting seat so that the plywood can be quickly turned over to the designated installation position in the storage tank without the need for auxiliary turning by the staff, thereby improving the efficiency of plywood installation.

[0027] 2. The provision of the first reinforced gear and the second reinforced gear respectively serves to further limit the rotation of the main drive gear and the second drive gear, thereby facilitating further ensuring the stability of the first reinforced gear and the second reinforced gear during rotation.

[0035] The following is combined with Figures 1 to 4 This application is described in further detail.

[0036] Embodiment 1:

[0037] The present application embodiment discloses a lifting tool. Figure 1 The lifting tooling includes a lifting fixed seat 1, a lifting mounting seat 2, a lifting clamping mechanism and a lifting rotation mechanism, wherein the cross-sections of the lifting fixed seat 1 and the lifting mounting seat 2 are both rectangular. In the embodiment of the present application, the length direction of the lifting fixed seat 1 is the x-axis direction, the width direction is the y-axis direction, and the height direction is the z-axis direction.

[0038] Reference Figure 2 and Figure 3 The hoisting rotation mechanism includes a first rotation assembly and a second rotation assembly, and the first rotation assembly and the second rotation assembly are used to drive the hoisting mounting seat 2 to rotate around the x-axis and the z-axis respectively. Specifically, the first rotation assembly includes a first motor 3, a first rotation gear 4, a main driving gear 5, a main bevel gear 6 and a slave bevel gear 7, wherein the first motor 3 is installed on the top of the hoisting mounting seat 1, the output shaft of the first motor 3 is passed through and rotated to fit the hoisting mounting seat 2, and the first rotation gear 4 is coaxially fixedly installed on the output shaft of the first motor 3, so that the first motor 3 drives the first rotation gear 4 to rotate.

[0039] Reference Figure 3The main driving gear 5 is rotatably mounted on the bottom of the hanging and fixing seat 1 and meshes with the first rotating gear 4. The main bevel gear 6 is coaxially fixedly mounted on the main driving gear 5, so that when the main driving gear 5 rotates with the first rotating gear 4, the main bevel gear 6 rotates together. The hanging and fixing seat 2 is provided with a mounting frame 8, and the mounting frame 8 includes a frame body 801 and a mounting shaft 802. The frame body 801 is fixedly connected to the top of the hanging and fixing seat 2. The mounting shaft 802 is horizontally arranged and both ends of the mounting shaft 802 are fixedly connected to the frame body 801. In the embodiment of the present application, the axis of the mounting shaft 802 is parallel to the length direction of the hanging and fixing seat 1. The mounting shaft 802 is rotatably matched with the hanging and fixing seat 1. The slave bevel gear 7 is coaxially fixedly mounted on the mounting shaft 802 and meshes with the main bevel gear 6, so that when the main bevel gear 6 rotates, the slave bevel gear 7 drives the mounting shaft 802 and the hanging and fixing seat 2 together around the axis direction of the mounting shaft 802, that is, the rotation of the hanging and fixing seat 2 around the x-axis is realized.

[0040] Reference Figure 2 and Figure 3 The second clamping assembly includes a second motor 9, a second rotating gear 10, a second driving gear 11 and a transmission shaft 12, wherein the second motor 9 is installed on the top of the lifting and fixing base 1, the first motor 3 and the second motor 9 are respectively arranged near the two ends of the length direction of the lifting and fixing base 1, the output shaft of the second motor 9 is passed through and rotated to cooperate with the lifting and fixing base 2, and the second rotating gear 10 is coaxially fixedly installed on the output shaft of the second motor 9, so that the second motor 9 drives the second rotating gear 10 to rotate.

[0041] Continue to refer to Figure 2 and Figure 3 , the transmission shaft 12 is vertically arranged and rotatably mounted at the bottom of the hanging fixed seat 1, the second driving gear 11 is coaxially fixedly mounted on the transmission shaft 12 and meshes with the second rotating gear 10, so that when the second rotating gear 10 rotates, the second driving gear 11 drives the transmission shaft 12 to rotate around the z-axis together. The main driving gear 5 is coaxially rotatably mounted on the transmission shaft 12, and the installation shaft 802 is penetrated and rotatably matched with the transmission shaft 12; when the first motor 3 and the second motor 9 simultaneously drive the first rotating gear 4 and the second rotating gear 10 to rotate synchronously in the same direction, the second driving gear 11 drives the transmission shaft 12 to rotate around its own axis, and the installation shaft 802 rotates around the axis of the transmission shaft 12 together with the transmission shaft 12. At this time, the main bevel gear 6 and the slave bevel gear 7 remain relatively stationary and rotate together around the axis of the transmission shaft 12, that is, the rotation of the hanging mounting seat 2 around the z-axis is finally realized, so as to facilitate the adjustment of the horizontal position of the hanging mounting seat 2.

[0042] In addition, when the first motor 3 is turned off or the first motor 3 drives the first rotating gear 4 to rotate, and the second motor 9 drives the second rotating gear 10 to rotate in the opposite direction, the second driving gear 11 drives the transmission shaft 12 to rotate around its own axis, and the installation shaft 802 rotates around the axis of the transmission shaft 12 together with the transmission shaft 12. At this time, due to the meshing between the slave bevel gear 7 and the main bevel gear 6, the installation shaft 802 and the hanging mounting seat 2 are driven to rotate synchronously around the axis direction of the installation shaft 802, thereby realizing the synchronous adjustment of the hanging mounting seat 2 in the horizontal and vertical directions, which is convenient and fast. When the first motor 3 is driven to rotate alone, the main driving gear 5 drives the main bevel gear 6 to rotate, and the slave bevel gear 7 drives the installation shaft 802 and the hanging mounting seat 2 to rotate around the axis direction of the installation shaft 802, that is, the hanging mounting seat 2 is rotated in the horizontal direction, thereby facilitating the rapid flipping of the hanging mounting seat 2.

[0043] Reference Figure 3 In order to further ensure the stability of the first rotating gear 4 and the second rotating gear 10 during rotation, the first rotating assembly also includes a first reinforcing gear 13, and the second rotating assembly also includes a second reinforcing gear 14, wherein the first reinforcing gear 13 is coaxially rotatably installed on the output shaft of the second motor 9 and meshes with the main drive gear 5, and the second reinforcing gear 14 is coaxially rotatably installed on the output shaft of the first motor 3 and meshes with the second drive gear 11, so as to further limit the rotation of the main drive gear 5 and the second drive gear 11, thereby ultimately ensuring the movement stability of the hoisting mounting base 2.

[0044] Reference Figure 1 In order to facilitate the protection of each gear during rotation, a protective cover 15 is also installed at the bottom of the lifting fixing base 1. The bottom of the protective cover 15 is open and covers the first rotating gear 4, the main driving gear 5, the second rotating gear 10 and the second driving gear 11.

[0045] Reference Figure 2 and Figure 4The hoisting clamping mechanism is arranged on the hoisting mounting seat 2 and is used to clamp and fix the workpiece. Specifically, the hoisting clamping mechanism includes two clamping seats 16 and a clamping movement component arranged opposite to each other, wherein the clamping seat 16 includes a clamping and fixing portion 161, a clamping portion 162 and a clamping connection portion 163. The clamping and fixing portion 161 and the clamping and connecting portion 163 are both rectangular plate-shaped, and the clamping and connecting portion 163 is located at the top of the clamping and fixing portion 161. The clamping portion 162 is arranged on the fixing portion and is distributed in plurality along the length direction of the clamping and fixing portion 161. When the two clamping seats 16 move in a direction approaching or away from each other, each clamping portion 162 realizes clamping or non-clamping of the workpiece, i.e., the plywood. The arrangement of the clamping portion 162 facilitates multi-point clamping of the workpiece, provides a more uniform clamping force, and facilitates the avoidance of the local clamping portion of the workpiece, so that the workpiece is not easily deformed during the clamping process. In the embodiment of the present application, the shape of the clamping portion 162 is cylindrical, and the clamping portion 162 is covered with a rubber sleeve during actual use to further reduce possible damage to the workpiece when clamped by the clamping portion 162 .

[0046] Reference Figure 4 A clamping and fixing sleeve 17 corresponding to the clamping portion 162 is fixedly installed on the top of the clamping and fixing portion 161, and each clamping portion 162 is respectively inserted into each clamping and fixing sleeve 17, and each clamping and fixing sleeve 17 is threadedly matched with a horizontally arranged fixing bolt 18, and each clamping portion 162 is tightly fixed in the clamping and fixing sleeve 17 by the fixing bolt 18. The setting of the clamping and fixing sleeve 17 increases the contact area between the clamping and fixing portion 161 and the clamping portion 162, which is convenient for fully ensuring the stability between each clamping portion 162 and the clamping and fixing portion 161; when the fixing bolt 18 is screwed and the position of each clamping portion 162 in the fixing sleeve is adjusted, it is convenient to adjust the length of the clamping portion 162 passing through the bottom of the clamping and fixing portion 161, so as to facilitate each clamping portion 162 to achieve stable clamping of the workpiece, i.e., plywood, under different circumstances, and has stronger applicability.

[0047] Continue to refer to Figure 4 The top of each clamping part 162 is penetrated by the clamping connection part 163 and slidably matched with the clamping connection part 163. The clamping connection part 163 is provided with a connecting bolt 19 corresponding to the clamping part 162 and arranged horizontally. Each connecting bolt 19 is threadedly matched with the clamping connection part 163 and pressed against the clamping part 162 to achieve the fixation between the clamping part 162 and the clamping connection part 163. The setting of the clamping connection part 163 facilitates the synchronous adjustment of multiple clamping parts 162 by moving the clamping connection part 163 on the basis of adjusting the length of the clamping part 162 alone, and the operation is simpler.

[0048] Reference Figure 2 and Figure 4The clamping motion assembly includes a clamping telescopic cylinder 20, a clamping driving rod 21 and a clamping connecting rod 22, wherein the clamping driving rod 21 is rotatably mounted at the bottom of the hoisting mounting seat 2, and the rotation point of the clamping driving rod 21 is close to the middle of its own length direction. Two clamping connecting rods 22 are provided, one end of the two clamping connecting rods 22 is rotatably mounted on the clamping driving rod 21 and is close to the two ends of the clamping driving rod 21 in the length direction, and the other ends of the two clamping connecting rods 22 are rotatably mounted on the clamping fixing parts 161 of the two clamping seats 16, so that when the clamping driving rod 21 rotates, the two clamping connecting rods 22 drive the two clamping seats 16 to move in a direction close to or away from each other.

[0049] Reference Figure 4 In the embodiment of the present application, two clamping telescopic cylinders 20 are provided, and both clamping telescopic cylinders 20 are horizontal and arranged along the width direction of the lifting mounting seat 2. The cylinder body of each clamping telescopic cylinder 20 is fixedly installed on the bottom of the lifting mounting seat 2, and the piston rod of each clamping telescopic cylinder 20 is fixedly installed on the clamping fixing part 161 of one of the clamping seats 16. When the clamping telescopic cylinder 20 drives its own piston rod to move, the two clamping seats 16 move towards or away from each other under the drive of the clamping connecting rod 22.

[0050] Reference Figure 1 and Figure 4 In order to further ensure the stability of the clamping seat 16 during movement, two groups of horizontally arranged clamping guide rails 23 are fixedly installed at the bottom of the lifting mounting seat 2. The cross-section of each clamping guide rail 23 is T-shaped and extends along the width direction of the lifting mounting seat 2. Each group of clamping guide rails 23 is provided with two and are distributed along the length direction of the lifting mounting seat 2. The two groups of clamping guide rails 23 are respectively penetrated and slidably matched with the clamping fixing parts 161 of the two clamping seats 16, so as to further limit the two clamping seats 16 when they move toward or away from each other, thereby facilitating to ensure the stability of the two clamping seats 16 during movement.

[0051] The implementation principle of a lifting tool in an embodiment of the present application is as follows: when the plywood needs to be installed, first, the clamping telescopic cylinder 20 drives the movement of its own piston rod so that the clamping parts 162 of the two clamping seats 16 can clamp and fix the workpiece, i.e., the plywood, and then the lifting and fixing seat 1 is lifted. When the plywood moves to a position close to the designated installation position, the lifting and mounting seat 2 is driven by the first motor 3 and the second motor 9 to rotate in the horizontal and vertical directions, so that the plywood can be quickly flipped and moved to the designated installation position in the storage tank without the need for auxiliary flipping by the staff, which is beneficial to improving the efficiency of plywood installation.

[0052] Embodiment 2:

[0053] Reference Figure 5The main difference between the embodiment of the present application and embodiment 1 is that the shape of the clamping portion 162 is different. The shape of the clamping portion 162 in the embodiment of the present application is selected to be a rectangular plate. The side of each clamping portion 162 of the two clamping seats 16 that is close to each other is provided with a rubber pad 24 by bonding and fixing, so that the clamping portion 162, on the one hand, further ensures the stability of the workpiece, i.e., the plywood, through a larger contact area, and on the other hand, simultaneously reduces the possible damage to the workpiece when it is clamped by the clamping portion 162.

[0054] The implementation principle of the present application embodiment is the same as that of embodiment 1, and will not be repeated here.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
