Technical Field
[0001] The present invention relates to the technical field of vacuum cavity processing hoists, in particular to a lifting hoist for vacuum cavity processing. Background Art
[0002] The vacuum chamber is a general term for the outer shell of equipment, such as the shell of a reactor, a cleaning machine, or a vacuum furnace. The manufacturing process involves cutting raw materials according to drawings, grinding, welding parts, assembling and welding, shaping, cleaning, and vacuum testing. As the outer shell of the equipment, the vacuum chamber is large in size and heavy in weight.
[0003] Currently, when assembling and welding a vacuum chamber or cutting raw materials, in order to ensure the stability of the vacuum chamber transfer process, it is generally necessary to use a lifting device to achieve the lifting, hoisting and transfer of the entire vacuum chamber.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] The present invention is provided with a flexible balance adjustment device, that is, when the lifting shell is unstable, the bidirectional adjustable transmission component provided inside the protective shell can be driven according to the left and right offset directions to realize left-shift transmission or right-shift transmission. With the lateral movement of the bidirectional adjustable transmission component, the clamping balance component provided on the left or right side of the protective shell can be driven accordingly to automatically clamp the cable firmly and automatically pull the balance and lift it, so that the pressure on the left and right sides of the lifting shell can be in a flat state. At the same time, when the bidirectional adjustable transmission component is running, the synchronous driving of the sliding balance component connected to the bottom will be realized, so that the roller and the connecting belt provided inside will be adjusted in lateral balance, and the center of gravity of the vacuum chamber lifting will be efficiently adjusted to the center, thereby achieving the advantages of safe lifting of the sling and the vacuum chamber and realizing self-balancing adjustment protection.
[0019] The setting of the transmission parts, that is, the arc-shaped heads provided on both sides of the outer end of the connecting shaft, can resist the blocks provided inside the slider to achieve transverse movement transmission, thereby realizing transverse movement balance adjustment transmission. Driven by the cylinder and the connecting frame, the arc-shaped heads on both sides of the connecting shaft can be flexibly adjusted and exposed to meet the left and right adaptive balance adjustment activities.
[0020] The arrangement of the slider, the stop block, the transmission rod, the first compression spring, the second compression spring and the pressure strip, that is, the transmission member can realize the lateral movement of the entire slider through the arc-shaped head and the stop block, so that the slider cooperates with the connecting arm connected on one side to realize the drive of the corresponding connected clamping balance component and realize self-balancing transmission. Under the cooperation of the elastic force of the first compression spring and the second compression spring, the automatic reset of the stop block and the slider can be efficiently realized, and the slider can realize the inward reset cooperation under the connection transmission of the internal transmission rod and the outer inclined surface of the pressure strip.
[0021] The setting of the clamping balance component, that is, the cross bar can pull the docking plate horizontally along with the connecting arm, so that the docking plate cooperates with the inclined groove opened at the upper end of the cross plate and the transmission of the clamping arm to realize the rapid clamping activity of the clamps and cables on both sides, ensuring the stability of the subsequent pulling balance adjustment process.
[0022] The arrangement of the cross bar, fixed plate, limit shaft and return spring, that is, the cross bar completes the cable clamping activity at the transmission docking plate, and can then pull the fixed plate to realize the lateral pulling of the clamping arm, clamping head and other parts. In this way, the clamping head in the clamping state can pull the cable to correspondingly lift the left or right lifting ear, thereby meeting the flexible adjustment of the self-balancing use of the lifting shell.
[0023] The setting of the clamp, that is, the pressure block arranged inside the clamping head, can be assisted by the elastic telescopic parts arranged at both ends of the inner side to strengthen the firmness of cable clamping, ensure the stability of subsequent pulling balance adjustment, and prevent it from slipping.
[0024] The setting of the sliding balance component, that is, when the transmission part moves along the main plate, can realize the synchronous transverse movement of the roller frame. In this way, the roller installed inside the roller frame can cooperate with the connecting belt transmission to realize flexible adjustment of the docking position. In this way, it can cooperate with the clamping balance component to realize double balance adjustment and enhance the lifting safety of the sling and the vacuum chamber.

DETAILED DESCRIPTION
[0035] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.
[0036] See also Figure 1-2 The present invention provides a lifting sling for vacuum chamber processing, including a lifting shell 1, with lifting ears 2 fixedly connected on the left and right sides of the upper end of the lifting shell 1, and cables 3 are docked inside the lifting ears 2 on both sides, a motor 4 is provided on the rear side of the lifting shell 1, and the front side of the motor 4 is connected to the first bevel gear 5, the front side of the first bevel gear 5 is meshed with a second bevel gear 6, and the middle part of the second bevel gear 6 is docked with a bidirectional screw 7, that is, screws with opposite external threads are provided on both sides of the outer end of the bidirectional screw 7, and connecting pipes 8 are threadedly docked on both sides of the bidirectional screw 7, and clamping claws 9 are provided on the end of the connecting pipes 8 on both sides away from one end of the bidirectional screw 7, the clamping claws 9 are arranged in the shape of two pairs of hooks, and the front and rear relative hooks are docked and combined through a connecting rod, and also includes a flexible balance adjustment device 10 provided at the upper end of the lifting shell 1.
[0037] When the vacuum chamber is to be hoisted, the lifting ears 2 provided on both sides of the upper end of the hoisting shell 1 can be connected to the cables 3 of the external hoisting equipment. The hoist can be moved to the upper end of the vacuum chamber to be hoisted through the external hoisting equipment, and the motor 4 provided in the middle of the rear side of the hoisting shell 1 can be driven to realize the meshing transmission of the first bevel gear 5 and the second bevel gear 6. In this way, the bidirectional screw 7 provided in the middle of the second bevel gear 6 will rotate to realize the transmission of the left and right side threaded connecting pipes 8, so that the connecting pipes 8 on both sides can realize relative lateral movement. As a result, the clamping jaws 9 on the left and right sides will be relatively close to realize the clamping and hoisting activities on the upper end of the vacuum chamber to meet the subsequent processing requirements.
[0038] See also Figure 3-4 The flexible balance adjustment device 10 in this embodiment includes a connecting plate 101 for connection with the upper end of the lifting shell 1, connecting rods 102 for connection vertically installed at the four corners of the connecting plate 101, and the outer ends of the four side connecting rods 102 are integrally provided with support springs to ensure the stability of the connection, a base 103 connected to the upper ends of the connecting rods 102 provided at the four corners, a protective shell 104 for protecting the internal structure installed on the upper end of the base 103, and a screw (not shown in the drawings) is installed horizontally on the upper end of the protective shell 104, and the left and right sides of the protective shell 104 are provided with a screw. The protective shell 104 is opened in the shape of a hollow groove, and a servo motor 105 is installed on the right side of the upper end of the protective shell 104, and the left output end of the servo motor 105 is connected to the screw provided at the upper end of the protective shell 104. A bidirectionally adjustable transmission component 106 is built into the middle end of the protective shell 104, and the middle part of the bidirectionally adjustable transmission component 106 is connected to the screw provided at the upper end of the protective shell 104. A clamping balance component 107 is symmetrically installed on the left and right sides of the protective shell 104 and connected to the left and right sides of the bidirectionally adjustable transmission component 106, and a sliding balance component 108 is installed at the lower end of the bidirectionally adjustable transmission component 106.
[0039] Among them, the bidirectionally adjustable transmission assembly 106 includes a main plate 1061 that is laterally fastened to the inside of the protective shell 104, and a transverse groove is opened inside the main plate 1061, a transmission member 11 is installed inside the main plate 1061 and slidably docked with the transverse groove opened inside the main plate 1061, and the middle of the transmission member 11 is connected to the screw provided at the upper end of the protective shell 104, and the auxiliary guide plates 1062 are laterally fastened to the outer ends of the main plate 1061, and the auxiliary guide plates 1062 on both sides are installed away from each other, and the sliders that can move left and right are correspondingly slidably installed inside the auxiliary guide plates 1062. 1063, a stop block 1064 movably embedded in the middle end of the slider 1063 and used for horizontal pushing transmission, a first compression spring 1065 installed at the bottom end of the stop block 1064 and arranged inside the slider 1063 to realize rebound reset support, a second compression spring 1066 connected to one side of the slider 1063 to realize horizontal movement and reset of the slider 1063, a horizontal axis 1067 installed on the side of the second compression spring 1066, a pressure strip 1068 fastened to one side of the outer end of the auxiliary guide plate 1062 for squeezing the stop block 1064, and a connecting arm 1069 fastened transversely to the side of the slider 1063 away from the second compression spring 1066.
[0040] Among them, the transmission member 11 includes a box body 111 installed inside the main plate 1061, a cylinder 112 installed on the left side of the box body 111, a connecting frame 113 docked at the telescopic end of the cylinder 112, and the right side of the connecting frame 113 extends to the middle of the box body 111, a connecting shaft 114 correspondingly vertically inserted into the right extension part of the connecting frame 113, and an arc head 115 symmetrically installed at the upper and lower ends of the connecting shaft 114 for horizontal pushing balance adjustment drive.
[0041] Among them, the block 1064 also includes a transmission rod 10641 inserted into the inside of the block 1064, and the position of the transmission rod 10641 is horizontally opposite to the pressure strip 1068. In this way, the block 1064 can be moved inward by the transmission rod 10641 and the outer side of the pressure strip 1068.
[0042] Among them, the outer side of the block 1064 is set in the shape of a smooth inclined surface, and the side of the block 1064 opposite to the transmission member 11 is a vertical flat surface; the pressure strip 1068 and the block 1064 are set horizontally symmetrically on the left and right sides, and the outer inclined surface of the pressure strip 1068 and the transmission rod 10641 set inside the block 1064 are in a left and right relative position.
[0043] When this hoist is hoisting the vacuum chamber, it is affected by the irregular shape of the vacuum chamber, so that the center of gravity of the vacuum chamber is not in a centered state. In this way, the hoisting pressure of the lifting ears 2 and the cables 3 provided on the upper ends of the left and right sides of the hoisting shell 1 will be inconsistent, that is, the side with the larger load-bearing pressure will be affected by the breakage. Therefore, after completing the clamping and hoisting activities of the clamping claws 9 on both sides and the vacuum chamber, the load-bearing conditions of the cables 3 on both sides can be observed. However, when the right cable 3 is in a larger load-bearing condition, the servo motor 105 provided on the right side of the upper end of the protective shell 104 can be driven to make the servo motor 105 realize the rotation of the screw provided on the upper end of the protective shell 104. As the screw rotates forward, the outer phase transmission connection transmission member 11 will be moved to the left, so that the transmission member 11 cooperates with the horizontal groove provided inside the main plate 1061 to realize smooth horizontal movement and drive activity. As the transmission member 11 moves left, the arc in the middle of the lower end of the box body 111 is exposed. The shaped head 115 will come into contact with the abutment 1064 provided inside the slider 1063 on one side, thereby indirectly realizing the leftward movement of the slider 1063 and guiding it through the auxiliary guide plate 1062. In this way, the slider 1063 can be pushed left to the position of the pressure bar 1068. At this time, the servo motor 105 will stop, so that the subsequent balanced and adjusted lifting shell 1 is in a stable state. As the slider 1063 moves left, the pulling of the connecting arm 1069 on one side can be realized to drive the clamping balance component 107 provided on the outside. In this way, the clamping balance component 107 will clamp the cable 3 and cooperate with the pulling of the connecting arm 1069 to contract the right cable 3 and lift the right lifting ear 2. In this way, it is ensured that the lifting shell 1 can be balanced and adjusted as a whole, and the center of gravity of the vacuum chamber lifting is centered, which ensures that the lifting pressure of the cables 3 on both sides is consistent, and reduces the excessive lifting pressure of the cables 3 on one side, which has the advantage of breaking.
[0044] After the transmission rod 10641 provided at the upper end of the block 1064 is in contact with the outer inclined surface of the pressure strip 1068 along with the transverse transmission, the reset preparation activity can be realized synchronously, that is, when the reset transmission activity is to be carried out, the servo motor 105 can be driven again to move the servo motor 105 to the left again to squeeze the block 1064 as a whole. In this way, the transmission rod 10641 provided at the upper end of the block 1064 can be in contact with the outer inclined surface of the pressure strip 1068 to realize the inward movement. As a result, the blocking state between the block 1064 and the arc head 115 can be released, thereby cooperating with the transverse movement of one side of the slider 1063. The compressed second compression spring 1066 can realize rapid transverse reset transmission to reset the slider 1063 to the right along the secondary guide plate 1062. At the same time, the block 1064 moved inward to the inside of the slider 1063 can cooperate with the first compression spring 1065 connected to the bottom end when it is away from the arc head 115 to realize rapid outward reset for the next balance adjustment transmission. Finally, when the transmission member 11 is moved to the right to the centered state, the arc head 115 will abut against the smooth upper end of the block 1064 during the reset process to squeeze the block 1064, thereby ensuring a smooth reset process of the entire transmission member 11.
[0045] When the left side of the lifting shell 1 is under too much pressure, the cylinder 112 provided inside the transmission part 11 needs to be driven in advance to shrink the cylinder 112 and pull the connecting frame 113 connected at the telescopic end. As a result, the connecting shaft 114 plugged into the right end of the connecting frame 113 can be moved to the opening on the other side of the box body 111, and the arc head 115 connected to the other end of the connecting shaft 114 can be moved out to realize the left side balance adjustment and horizontal push transmission. In this way, the left side clamping and balancing assembly 107 can be driven conveniently through the transmission of the arc head 115 and the block 1064, and the block 1064 and the pressure strip 1068, just like the above steps, so that the left side clamping and balancing assembly 107 clamps and pulls the cable 3 to adjust the balance of the left side of the lifting shell 1, thereby driving the self-balancing cooperation of the lifting shell 1, making the lifting pressure of the cables 3 on both sides consistent, and reducing the occurrence of uneven force and breakage.
[0046] See also Figure 7-8 The clamping balance component 107 in this embodiment includes a cross bar 1071 that is laterally inserted into the left and right sides of the protective shell 104 and connected to the side of the connecting arm 1069 provided inside the bidirectionally adjustable transmission component 106. The cross bar 1071 can be moved laterally to achieve clamping transmission and pulling balance adjustment, and a disc is integrally fixed to the outer end of the cross bar 1071, which is correspondingly fastened to a docking plate 1072 on the outer side of the cross bar 1071, and both sides of the outer end of the docking plate 1072 are embedded in the protective shell 104 and fastened to the cross plates 1073 on the side surfaces of the embedded ends of the docking plate 1072. The upper ends of the cross plates 1073 on both sides are provided with inclined grooves, and the transmission is connected to the inclined grooves opened on the upper ends of the cross plates 1073 and can move The clamping arm 1074 used for clamping transmission, the clamping head 12 installed on the outside of the clamping arm 1074 for clamping and pulling the cable 3, and the corresponding supporting plates 1075 installed at the lower ends of the horizontal plates 1073 on both sides for guiding and supporting, are fastened to the fixing plates 1076 on the inner sides of the supporting plates 1075 on both sides, and the middle part of the fixing plate 1076 is movably connected to the cross bar 1071, and the limiting shafts 1077 on both sides of the interior of the symmetrical horizontal fixing plate 1076, and the limiting shafts 1077 on both sides pass through the inside of the docking plate 1072 on both sides, and are movably inserted into the inside of the two ends of the side of the protective shell 104, docked on the sides of the limiting shafts 1077 on both sides and arranged inside the protective shell 104. The reset spring 1078 that can be used for resetting the elastic transmission is
[0047] Specifically, the clamp 12 includes a clamping head 121 that is correspondingly fastened to the outer ends of the clamping arms 1074 on both sides for fastening and clamping, a pressure block 122 installed inside the clamping head 121, and a triangular recess is correspondingly opened in the middle of the pressure block 122 to enhance the clamping and fastening effect, and an elastic telescopic rod 123 that is connected to the left and right ends of the inner side of the pressure block 122 to achieve elastic pressure support.
[0048] Specifically, the cross bar 1071 is fixedly connected and movably connected to the docking plate 1072 and the fixed plate 1076, and there is a distance between the docking plate 1072 and the fixed plate 1076, so that the cross bar 1071 pulls the docking plate 1072 in advance to perform a clamping activity, and realizes a pulling balance adjustment activity on the transmission fixed plate 1076; the cross plate 1073 slides against the upper end of the support plate 1075, and the upper end of the cross plate 1073 is connected to the side limit plug-in combination of the upper end of the support plate 1075, so that the clamping arm 1074 can be stably moved and clamped for transmission through the limit cooperation of the support plate 1075.
[0049] When the slider 1063 on one side of the bidirectionally adjustable transmission component 106 is driven by the arc head 115 on the opposite side and the block 1064, the synchronous transverse movement causes the connecting arm 1069 laterally fastened to one side of the slider 1063 to realize the synchronous pulling of the cross bar 1071 connected to the outer end, that is, the cross bar 1071 can pre-pull the docking plate 1072 fastened to the outer end, so that the docking plate 1072 synchronously pulls the cross plate 1073 connected to the side edges of the two ends. In this way, the cross plates 1073 on both sides can cooperate with the inclined The groove is used to realize the outward push transmission of the clamping arm 1074, so that the clamping arms 1074 on both sides cooperate with the clamping heads 12 set at the corresponding outer ends to clamp and contact the outer side of the cable 3. At the same time, when the clamping head 121 set inside the clamping head 12 is connected with the cable 3, the pressure block 122 installed inside the clamping head 121 can be supported by the elastic force of the elastic telescopic rods 123 set at both ends of the inner side to strengthen the tight fit of the cable 3, so that the clamping heads 12 on both sides firmly clamp the cable 3 and are not easy to loosen or fall off, thereby realizing the subsequent stable pulling balance adjustment preparation;
[0050] When the cross bar 1071 pulls the docking plate 1072 horizontally to complete the clamping and docking activity of the cable 3, the fixed plate 1076, which is relatively arranged on one side of the docking plate 1072 and movably connected to the outer side of the cross bar 1071, will move horizontally accordingly to realize the horizontal movement and pulling of the supporting plates 1075 connected on both sides of the outer end. As the supporting plates 1075 on both sides move horizontally, the horizontal movement of the upper end limit connection clamping arms 1074 can be realized. In this way, the cable 3 clamped by the clamps 12 on both sides will be pulled to realize the lifting transmission of the lifting ear 2 provided on one side of the lifting shell 1 connected to the bottom. In this way, the overall balance adjustment of the lifting shell 1 can be realized, the center of gravity of the vacuum chamber can be flexibly adjusted to the center, and the occurrence of the deviation of the lifting center of gravity can be reduced.
[0051] At the same time, when the fixed plate 1076 moves, it will cooperate with the limit shafts 1077 opened on both sides of the interior to ensure the stability of the lateral movement of the fixed plate 1076. At the same time, when the limit shafts 1077 are inserted into the interior of both sides, the compression of the reset springs 1078 connected to the outer ends can be realized. In this way, when the clamping and pulling balance activities of the cable 3 are subsequently released, the elastic reset assistance can be realized, so that the fixed plate 1076 can be automatically reset and moved as a whole to realize the next balance adjustment. Therefore, when the lifting shell 1 is balanced, it can be pre-clamped and docked, and then horizontally pulled and lifted for balance adjustment, meeting the needs of efficient and flexible balance adjustment without too many cumbersome steps and equipment installation settings.
[0052] See also Figure 9 The sliding balancing assembly 108 in this embodiment includes a roller frame 1081 that is connected to the lower end of the protective shell 104 and connected to the lower end of the transmission member 11, a roller 1082 that is longitudinally rotatably connected to the inside of the roller frame 1081 to realize lateral auxiliary balancing adjustment, and a limit groove 1083 symmetrically provided at the outer end of the roller 1082 for connecting and limiting.
