Description

Technical Field

[0001] The invention belongs to the technical field of cranes, and in particular relates to a hanging assembly for a crane winch. Background Art

[0002] A crane is a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called an overhead crane, an overhead crane, or a crane. Since the birth of the crane, the swing of the hoisted objects during the crane hoisting process has been a problem that has troubled people. When the hoisting trolley moves, due to the dynamic characteristics of the system and the influence of external interference (wind, air damping), the flexible wire rope is difficult to control the swing of the hoisted objects. The swing reduces the efficiency of transportation and loading and unloading, and is prone to collision accidents and economic losses.

[0003] At present, people use two basic ways to control the swing: 1. Mechanical anti-swing technology, such as cross wire rope anti-swing device seesaw anti-swing device, etc. Mechanical anti-swing requires a large degree of manual intervention, and the effect is not obvious, which cannot meet the efficiency requirements of modern production, transportation and loading and unloading; 2. Electronic anti-swing technology, which is to establish a mathematical model of the swing of the hoisted object, linearize and simplify the swing, and is only applicable to small-angle swing, and then use the optimization method to control it. Because the model cannot reflect the actual situation, the swing control cannot achieve the expected effect, the applicability is poor, and needs to be improved. In addition, when the current crane hangs the pipe, it generally uses a hook and a strap to cooperate with the hoisting. When the winch is started or stopped, when the winch swings, the pipe is prone to slip due to inertia problems, and it is separated from the strap and the hook, and the pipe falls off, which not only causes damage to the pipe but also affects the construction safety.

[0020] In addition, when hoisting is performed through this scheme, compared with the traditional hoisting method, the stroke of the upper pull rope is D1 and D2, the stroke of the lower pull rope is D3 and D4, and the angle between D1 and D2 is 2a; then D1cosa+D2cosa=D3cosa+D4cosa; the stroke relationship of the traditional three-point hoisting scheme is: FD11cosa+D12cosa=D5; if the weight of the object hoisted by this scheme and the traditional scheme is the same, it can be concluded that D1cosa+D2cosa=D11cosa+D12cosa; therefore, it can be known that D3cosa+D4cosa=D5, then it can be concluded that D5>D3cosa; D5>D4cosa, the value range of cosa is (0-1), so compared with the traditional hoisting scheme, the hoisting stroke of this scheme is shorter, the required length of the upper pull rope and the lower pull rope is shorter, and the swing amplitude is smaller.

[0021] In addition, when the present invention is to hoist the pipe, especially the round pipe or the triangular pipe, the pipe is first clamped and fixed by the first clamping mechanism and the second clamping mechanism. When fixing, the distance between the first clamping mechanism and the second clamping mechanism is adjusted by the adjusting mechanism. The specific adjustment process is that when the rotating block is rotated clockwise, the rotating block drives the rotating shaft to rotate, and the rotating shaft simultaneously drives the two symmetrically arranged bevel gears 1 to rotate, thereby driving the bevel gear 2, the transmission drawer, the bevel gear 3, and the bevel gear 4 to rotate. Since the two bevel gears 1 are symmetrically arranged, when rotating, the directions of driving the two bevel gears 2 to rotate are opposite, and the rotation directions of the two bevel gears 3 and the two bevel gears 4 are opposite. The threaded rod of the first clamping mechanism rotates counterclockwise, and the threaded rod of the second clamping mechanism rotates clockwise. The spiral structures of the threaded rods of the first clamping mechanism and the second clamping mechanism are opposite. Therefore, when the threaded rods of the first clamping mechanism and the second clamping mechanism rotate in opposite directions, the two connecting blocks can be driven to make similar movements, and the threaded rod drives the connecting block to push the fixing block in the box body. The movable block 2 and the movable block 3 extend out of the box body at the same time. When they contact the round pipe, the movable block 2 and the movable block 3 do not contact the pipe surface at the same time because the pipe is not a planar structure. If the movable block 3 contacts the pipe first, the movable block 3 will stop moving first, and the fixed block will continue to drive the movable block 2 to move. At this time, the sliding column 3 slides in the sliding groove 3. At the same time, the end of the movable block 3 that contacts the movable block 1 will push the movable block 1 upward through the inclined surface setting, and the inclined surface setting of the movable block 1 and the movable block 2 will continue to push the movable block 1 to the right. The movable block 2 moves only until the movable block 2 presses the pipe, and the movable block 2 and the movable block 3 complete the pressing of the special-shaped pipe such as the round pipe or the triangular pipe. Through the above-mentioned arrangement, the gravity of the round pipe can be coordinated during hoisting, and the automatic clamping adjustment can be completed through the gravity and the movable block 2 and the movable block 3, which not only improves the clamping effect, but also improves the clamping efficiency, and quickly completes the hoisting operation of the special-shaped pipe. It works together with the square swing mechanism to prevent the pull rope from falling off due to uneven force on the pipe when it swings.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The invention discloses a hanging assembly for a crane winch. Compared with a traditional hanging scheme, the hanging stroke of the scheme is shorter, the required upper and lower pull ropes are shorter, and the swing amplitude is smaller.

[0024] By setting an adjusting mechanism in cooperation with the first clamping mechanism and the second clamping mechanism, the gravity of the round pipe is cooperated during hoisting, and automatic clamping adjustment is completed through the gravity and the moving blocks two and three, which not only improves the clamping effect, but also improves the clamping efficiency, and quickly completes the hoisting operation of the special-shaped pipe. It works together with the square swing mechanism to prevent the pull rope from falling off due to uneven force on the pipe when swinging.

[0025] The upper pull rope is prevented from being gathered together, entangled and rotated by the buffering effect of the upper shock-absorbing part, and the lower pull rope is prevented from being gathered together, entangled and rotated by the buffering effect of the lower shock-absorbing part, thereby increasing the stability of the lifting; the swing of the lower pull rope is buffered by the joint action of the upper anti-swing part and the lower shock-absorbing part arranged at the bottom of the support frame, and the swing amplitude is reduced by limiting the swing of the upper and lower pull ropes, thereby improving the transportation and loading and unloading efficiency of the lifting, and preventing collision accidents and economic losses.

[0026] The locking rod provided can prevent the sealing plug from leaking and ensure the air pressure in the sealing cylinder, thereby better preventing the upper pull rope from swinging and further improving the stability of the lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The upper shock absorber 9 and the lower shock absorber 11 have the same structure, both of which include a conduit 111, and the two ends of the conduit 111 are slidably connected to the guide rods 112, and the other ends of the two guide rods 112 are connected to the sliding blocks 113, and the outer sides of the conduit 111 and the guide rods 112 are provided with a first spring 114, and the two ends of the first spring 114 are connected to the sliding blocks 113; the sliding block 113 is slidably connected to the through groove of the support frame 1, and a middle hole is longitudinally opened in the center of the sliding block 113, and the upper pull rope 4 and the lower pull rope 5 can both pass through the middle hole and are slidably connected to the middle hole.

[0046] The upper anti-swaying member 12 is arranged on both sides of the lower shock absorbing member 11, and the upper anti-swaying member 12 is connected to the sliding block 113 of the lower shock absorbing member 11; the upper anti-swaying member 12 includes an outer shell 121, an inner shell 122 is arranged inside the outer shell 121, an insulation layer is arranged between the outer shell 121 and the inner shell 122, the insulation layer is made of asbestos and glass fiber, the inner shell 122 is a double-layer cylinder, and a thermofluid body 123 is installed inside the cavity formed by the double-layer structure, and the thermofluid body 123 melts when heated and solidifies when cooled; a ball nut 124 is arranged on the inner side of the inner shell 122, and the ball nut 124 is matched with a lead screw 125, and the other end of the lead screw is connected to the sliding block 113 of the lower shock absorbing member 11; a friction block 126 is arranged on the outer side of the ball nut 124, and the friction block 126 is frictionally connected to the inner shell 122, and a plurality of heat-conducting rods 127 are connected to the side of the inner shell 122 close to the friction block 126.

[0047] The thermofluid body 123 is composed of rubber material, lead alloy, tin alloy and antimony alloy in proportion, and the mass ratio satisfies (3-5): (1.2-2): (1.2-2): (1.2-2); when heated to 120-150°C, the thermofluid body 123 will be transformed from a solid state into a flowing liquid structure.

[0048] During hoisting, the upper pull rope 4 is tightened by the pulling force of the winch, and the lower pull rope 5 is tightened by the gravity of the pipe. After being tightened, the angles of the upper pull rope 4 and the lower pull rope 5 become smaller. The upper pull rope 4 is prevented from being gathered together to be entangled and rotated by the buffering effect of the upper shock-absorbing member 9, and the lower pull rope 5 is prevented from being gathered together to be entangled and rotated by the buffering effect of the lower shock-absorbing member 11, thereby increasing the stability of the hoisting. When the winch starts to water on the crane arm During horizontal movement, the pipe will swing due to the inertia. The upper anti-sway member 10 and the upper shock-absorbing member 9 arranged on the top of the support frame 1 can buffer the swing of the upper pull rope 4. The upper anti-sway member 12 and the lower shock-absorbing member 11 arranged on the bottom of the support frame 1 can buffer the swing of the lower pull rope 5. By limiting the swing of the upper pull rope 4 and the lower pull rope 5, the swing amplitude is reduced, thereby improving the transportation and loading and unloading efficiency of the hoisting, preventing collision accidents and economic losses.

[0049] The working process of the upper anti-sway member 10 is as follows: the upper anti-sway member 10 is arranged on both sides of the upper pull rope 4. When the upper pull rope 4 swings to one side, on the one hand, the upper shock-absorbing member 9 is provided to buffer and reduce the swing amplitude. On the other hand, the upper pull rope 4 on one side pulls the sliding block 113 to slide in the support frame 1. The sliding block 113 drives the piston body 102 to compress the gas in the sealing cylinder 101. The end of the sealing cylinder 101 is sealed by the one-way ventilation mechanism provided. When the piston body 102 is compressed, the pressure of the one-way ventilation mechanism increases and the seal is performed. When the piston body 102 moves in the opposite direction, the pressure decreases, and the one-way ventilation mechanism opens the air intake. ; The compressed air in the sealing cylinder 101 is used to buffer the reaction formed by the sliding block 113 and the upper pull rope 4, thereby reducing the amplitude of the upper pull rope 4; at the same time, the upper pull rope 4 on the other side pulls the piston body 102 outward through the sliding block 113, and the piston body 102 generates negative pressure, and the one-way ventilation mechanism takes in air. When the piston body 102 moves to the end of the sealing tube 109, the gas in the sealing cylinder 101 is discharged through the air vent 1015 to form a connection, thereby preventing the air pressure in the sealing cylinder 101 from being too high and the piston body 102 from being unable to be compressed; when the upper pull rope 4 swings in the opposite direction, the process of the upper anti-sway parts 10 on both sides is opposite to the above.When the one-way ventilation mechanism is working, the pressure in the sealing cylinder 101 may be too high, and the sealing plug 106 cannot be opened. In order to prevent the above situation from happening, the vent hole 1015 is set. When the piston body 102 moves to the end of the sealing cylinder 101 close to the sliding block 113, the piston body 102 does not block the vent hole 1015, and the vent hole 1015 is vented, so that the air pressure in the sealing cylinder 101 is balanced with the outside, thereby preventing the pressure in the sealing cylinder 101 from being too high. At the same time, there will be a situation when When the sealing cylinder 101 is in a pressure balance state, the sealing plug 106 is not tightly sealed, and the gas in the sealing cylinder 101 will be discharged from the through hole 105, and the air pressure will decrease, thereby affecting the anti-swing performance. In order to avoid the above situation, a locking rod 1012 is provided to lock the sealing plug 106. The specific working process of the locking rod 1012 is that when the piston body 102 moves close to one side of the movable block, the sealing cylinder 101 is subjected to negative pressure, the pressure is reduced, and the pressure of the connecting cavity 1011 connected through the vent pipe 108 is reduced, and the movable block is closed. The plug plate 1010 moves due to the elastic force of the third spring 1013, driving the locking rod 1012 to disengage from the insertion hole 1014, and then the sealing plug 106 is opened by the negative pressure, and the sealing cylinder 101 completes the air intake through the through hole 105; when the piston body 102 is compressed, the pressure in the sealing cylinder 101 increases, the sealing plug 106 is closed due to the pressure, and the pressure in the connecting cavity 1011 connected to the vent pipe 108 increases, pressing the piston plate 1010 and the locking rod 1012 to move, and the third spring 1013 is pressed. Under compression, the locking rod 1012 is inserted into the socket 1014 to lock it; it should be understood that even if the locking rod 1012 reaches the specified position first, the sealing plug 106 will compress and move the locking rod 1012 through the arc setting at the end of the locking rod 1012 until the locking rod 1012 slides into the socket 1014 to lock it; the setting of the locking rod 1012 can prevent the sealing plug 106 from leaking, ensure the air pressure in the sealing cylinder 101, thereby better preventing the upper pull rope 4 from swinging, and further improving the stability of the lifting.

[0050] Embodiment 2:

[0051] Please refer to Figure 5-7On the basis of the first embodiment, the upper anti-sway member 10 is arranged on both sides of the upper shock-absorbing block, and the upper anti-sway block is connected to the sliding block 113 of the upper shock-absorbing member 9; the upper anti-sway block includes a sealing cylinder 101, a piston body 102 is arranged inside the sealing cylinder 101, a moving rod 103 is connected to one side of the piston body 102, the other end of the moving rod 103 passes through the sealing cylinder 101 and the sliding block 113 of the upper shock-absorbing block is connected to the moving rod 103; a partition 104 is provided at one end of the sealing cylinder 101 away from the upper shock-absorbing body, the partition 104 is provided with a through hole 105, and the through hole 105 is provided with a one-way ventilation mechanism, and the one-way ventilation mechanism allows the gas outside the sealing cylinder 101 to enter the inside of the sealing cylinder 101; a vent hole 1015 is provided on the side wall of the end of the sealing cylinder 101 away from the partition 104.

[0052] The one-way ventilation mechanism includes a sealing plug 106, which can perform sealing crimping on the through hole 105. The other side of the sealing plug 106 is connected to a second spring 107, and the other end of the second spring 107 is connected to the inner wall of the through hole 105. The sealing plug 106 is provided with a locking piece, which performs plug-in locking on the sealing plug 106. The locking member includes a sealing tube 109, inside which a piston plate 1010 is arranged, one side of the piston plate 1010 is a connecting chamber 1011, and the other side of the piston plate 1010 is connected to a locking rod 1012, on which a third spring 1013 is arranged, one end of the third spring 1013 is connected to the piston plate 1010, and the other end is connected to the inner wall of the sealing tube 109; the locking rod 1012 is arranged through the sealing tube 109, and the locking rod 1012 extends into the through hole 105, and a socket 1014 is provided on the side wall of the sealing plug 106, and the inner wall of the socket 1014 is a hemispherical structure, and the locking rod 1012 and the socket 1014 can be plugged in correspondingly; the connecting chamber 1011 is connected to a ventilation pipe 108, and the ventilation pipe 108 is connected to the interior of the sealing cylinder 101.

[0053] The working process of the lower anti-swaying member 12 is that when the lower pull rope 5 swings, on the one hand, it is buffered by the lower shock absorbing member 11, and on the other hand, when the lower pull rope 5 swings, the sliding block 113 is pulled horizontally to slide back and forth in the support frame 1, and the sliding block 113 drives the lead screw 125 to move horizontally, thereby driving the ball nut 124 to rotate, and the ball nut 124 drives the friction block 126 to rub against the inner side wall of the inner shell 122, and heat is generated during the friction process, which is transferred to the cavity of the inner shell 122 through the heat conducting rod 127. When the temperature reaches 120 degrees Celsius, the thermofluid body 123 composed of rubber material, lead alloy, tin alloy and antimony alloy melts and becomes liquid. After forming the liquid state, when the pull-down rope 5 drives the support frame 1 to swing, the liquid medium inside the inner shell 122 will form a reaction force on the support frame 1 due to inertia, thereby reducing the swing amplitude of the pull-down rope 5 and the support frame 1, further improving the anti-swing effect; and combined with the anti-swing component 10 and the shock-absorbing component, they work together to further improve the stability of the winch hoisting.

[0057] Both ends of the moving block 1 75 are provided with inclined surfaces, the end of the moving block 2 76 close to the moving block 1 75 is provided with an inclined surface, and the end of the moving block 3 77 close to the moving block 1 75 is provided with an inclined surface; through the setting of the inclined surfaces, the moving blocks 2 76 and the moving blocks 3 77 can drive the moving block 1 75 to move longitudinally when they move horizontally. The moving block 1 75 is provided with a slide groove 1 78, and a slide column 1 79 is provided in the slide groove 1 78, and the slide column 1 79 is connected to the fixed block 73. The moving block 2 76 is provided with a slide groove 2 710, and a slide column 2 711 is provided in the slide groove 2 710, and the slide column 2 711 is connected to the fixed block 73.

[0058] In this solution, when hoisting pipes, especially round pipes or triangular pipes, the first clamping mechanism 7 and the second clamping mechanism 8 are first used to clamp and fix the pipes. When fixing, the distance between the first clamping mechanism 7 and the second clamping mechanism 8 is adjusted by the adjusting mechanism 6. The specific adjustment process is that when the rotating block 63 is rotated clockwise, the rotating block 63 drives the rotating shaft 62 to rotate, and the rotating shaft 62 simultaneously drives the two symmetrically arranged bevel gears 65 to rotate, thereby driving the bevel gear 2, the transmission pump, the bevel gear 3 67, and the bevel gear 4 68 to rotate. Since the two bevel gears 2 65 The two bevel gears 67 and 68 are symmetrically arranged. When rotating, the directions of driving the two bevel gears 2 to rotate are opposite. Then, the directions of rotation of the two bevel gears 3 67 and the two bevel gears 4 68 are opposite. The threaded rod 72 of the first clamping mechanism 7 rotates counterclockwise, and the threaded rod 72 of the second clamping mechanism 8 rotates clockwise. The spiral structures of the threaded rods 72 of the first clamping mechanism 7 and the second clamping mechanism 8 are opposite. Therefore, when the threaded rods 72 of the first clamping mechanism 7 and the second clamping mechanism 8 rotate in opposite directions, the two connecting blocks 74 can be driven to make similar movements. The threaded rod 72 drives the connecting block 74 to push the fixing block 73 on the box body 7. 1, and the moving block 2 and the moving block 3 77 extend out of the box body 71. When they contact the circular pipe, since the pipe is not a planar structure, the moving block 2 76 and the moving block 3 77 do not contact the pipe surface at the same time. If the moving block 3 77 contacts the pipe first, the moving block 3 77 will stop moving first, and the fixed block 73 will continue to drive the moving block 2 76 to move. At this time, the sliding column 3 713 slides in the sliding groove 3 712. At the same time, the end of the moving block 3 77 that contacts the moving block 1 75 is set by the inclined surface, which will push the moving block 1 75 upwards. The inclined surface of the moving block 1 75 and the moving block 2 76 The surface setting will continue to push the moving block 2 76 to move to the right until the moving block 2 76 presses the pipe, and the moving block 2 76 and the moving block 3 77 complete the compression of the round pipe or the triangular pipe. And through the above setting, during hoisting, the gravity of the round pipe is cooperated, and the automatic clamping adjustment is completed through the gravity and the moving block 2 76 and the moving block 3 77, which not only improves the clamping effect, but also improves the clamping efficiency, quickly completes the hoisting operation of the special-shaped pipe, and works together with the square swing mechanism to prevent the pull rope from falling off due to uneven force on the pipe when swinging.

[0059] Embodiment 4:

[0060] like Fig.13As shown, when the present invention is used for lifting, compared with the traditional lifting method, the stroke of the upper pull rope 4 is D1 and D2, the stroke of the lower pull rope 5 is D3 and D4, and the angle between D1 and D2 is 2a; then D1cosa+D2cosa=D3cosa+D4cosa; the stroke relationship of the traditional three-point lifting scheme is: FD11cosa+D12cosa=D5; if the weight of the object lifted by the present invention and the traditional scheme is the same, it can be concluded that D1cosa+D2cosa=D11cosa+D12cosa; therefore, it can be known that D3cosa+D4cosa=D5, and it can be concluded that D5>D3cosa; D5>D4cosa, the value range of cosa is (0-1), so the present invention has a shorter lifting stroke than the traditional lifting scheme, the required length of the upper pull rope 4 and the lower pull rope 5 is shorter, and the swing amplitude is smaller.

[0061] The device obtained by the above technical solution is a hanging assembly for a crane winch. Compared with the traditional lifting solution, this solution has a shorter lifting stroke, shorter upper and lower pull ropes, and smaller swing amplitude. The setting adjustment mechanism cooperates with the first clamping mechanism and the second clamping mechanism, cooperates with the gravity of the round pipe during lifting, and completes automatic clamping adjustment through gravity and the moving blocks two and three, which not only improves the clamping effect, but also improves the clamping efficiency, quickly completes the lifting operation of the special-shaped pipe, and works together with the square swing mechanism to prevent the pull rope from falling off due to uneven force on the pipe when swinging. The upper pull rope is prevented from being gathered together, entangled and rotated by the buffering effect of the upper shock absorber, and the lower pull rope is prevented from being gathered together, entangled and rotated by the buffering effect of the lower shock absorber, thereby increasing the stability of the hoisting; the swing of the lower pull rope is buffered by the joint action of the upper anti-swaying part and the lower shock absorber set at the bottom of the support frame, and the swing amplitude is reduced by limiting the swing of the upper and lower pull ropes, thereby improving the transportation and loading and unloading efficiency of the hoisting, preventing collision accidents and causing economic losses. The locking rod can prevent the sealing plug from leaking and ensure the air pressure in the sealing cylinder, thereby better preventing the swing of the upper pull rope and further improving the stability of the hoisting.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations; any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
