Description

Technical Field

[0001] The invention belongs to the field of cranes, and in particular relates to a windproof crane alignment device. Background Art

[0002] Cranes are commonly used lifting and transportation equipment in freight hubs such as freight terminals. They are used to transport heavy goods over short distances. The crane lifts the goods through the clamping mechanism at the lower end of the lifting head and then transports them to the freight location.

[0003] Most traditional cranes only lift the entire cargo through a simple clamping mechanism at the lower end. During operation, the crane generally lifts the cargo to a higher position for transportation. The horizontal wind at high altitudes is generally strong, especially along the coasts of rivers, seas and lakes such as ports. Strong horizontal winds will blow the cargo in the air, causing the cargo to swing with the wind, which not only increases the load-bearing capacity of the crane rope, but also makes it difficult for the swinging cargo to align with the cargo on the ground during the descent, thereby neatly stacking the cargo. The center of gravity of the unevenly placed cargo is unstable, and dangerous accidents are prone to occur.

[0004] Therefore, we propose a windproof crane alignment device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a windproof crane alignment device which can neatly stack goods, in view of the problem that most traditional cranes are difficult to align with goods on the ground under the influence of lateral wind.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a windproof crane alignment device, comprising a horizontally arranged lifting plate, the side walls around the lifting plate are fixedly connected with a vertically arranged transmission box, a plurality of driving gears are rotatably connected in the transmission box, each of the driving gears is provided with a driven gear meshing with the driving gear at the lower end, a plurality of the driven gears are rotatably connected to the inner side wall of the transmission box, a friction layer is fixedly connected to the side wall of the driven gear close to the inner side wall of the transmission box, the rotating shaft of each driving gear extends to the outside of the transmission box and a fan is fixedly installed thereon, an elastic layer is fixedly embedded on the outer side wall of each transmission box, and a windproof mechanism and a gravity adjustment mechanism are respectively provided at the lower end and inside of the lifting plate.

[0007] In the above-mentioned windproof crane alignment device, the windproof mechanism includes a horizontal plate slidably connected between multiple transmission boxes, and multiple elastic bellows containing evaporative liquid are fixedly connected between the horizontal plate and the lower side wall of the lifting plate. The multiple elastic bellows are connected to the multiple transmission boxes through conduits.

[0008] In the above-mentioned windproof crane alignment device, the gravity adjustment mechanism includes a cavity opened inside the lifting plate, a rotating column is rotatably connected in the cavity, the upper end of the rotating column extends to the outside of the cavity and is fixedly connected to a guide plate, a turntable is fixedly sleeved outside the rotating column, and a counterweight block is fixedly embedded on the turntable.

[0009] In the above-mentioned windproof crane alignment device, a vertical slot is provided outside the rotating column, a limit block matching the vertical slot is installed on the inner wall of the turntable, and a flow cavity containing counterweight liquid is provided inside the turntable.

[0010] In the above-mentioned windproof crane alignment device, the vertical groove and the limit block are clearance-matched.

[0011] Compared with the existing technology, the advantages of this windproof crane alignment device are:

[0012] 1. The present invention is provided with a transmission box. When the whole device drives the goods to rise to a high altitude, the multiple wind-blowing fans on the windward side will drive the driving gear in the transmission box to rotate under the blowing of the lateral wind, and drive the driven gear meshing with it to rotate. The friction layer on the side wall of the driven gear will rotate relative to the inner wall of the transmission box. The heat generated by friction will cause the evaporative liquid in the transmission box to evaporate, so that the elastic layer on the side wall of the transmission box bulges outward under the action of air pressure, so that the wind resistance of the outer wall of the transmission box facing the windward side is greatly reduced, thereby reducing the shaking amplitude of the goods in the air, and ensuring that the goods can be neatly stacked with the goods on the ground during the descent.

[0013] 2. The present invention is provided with a windproof mechanism. Under normal circumstances, the evaporative liquid is in a plurality of elastic bellows. When lifting goods, the goods are fixed in the space surrounded by a plurality of transmission boxes and the lifting plates. The horizontal plate will rest against the upper end of the goods. During the descent of the device, the plurality of elastic bellows will be compressed, and the evaporative liquid therein will be squeezed into the transmission box through the conduit, so as to reduce the amplitude of the shaking of the goods in the air and play the role of automatically injecting the evaporative liquid. After use, when the goods are unloaded from the device, the evaporative liquid will return to the elastic bellows under the suction of the elastic bellows, and can play a good containing role again.

[0014] 3. The present invention provides a gravity adjustment mechanism. When the goods are blown by the lateral wind, the guide plate on the upper end of the lifting plate will be stabilized in the direction with the least wind resistance. During the stabilization process, the turntable will be driven to rotate in the cavity through the rotating column, and the counterweight block on the turntable will be rotated to the end of the lifting plate away from the windward side. The gravity of the counterweight block itself causes the entire device to be subjected to a force in the opposite direction, counteracting the tilting movement tendency of the device under the action of the lateral wind resistance, further reducing the swing amplitude of the goods, and ensuring that the goods can be neatly stacked with the goods on the ground during the descent.

[0015] 4. The present invention sets a flow cavity and a vertical groove, and the vertical groove is matched with the gap of the limit block, so that the entire turntable is movably connected in the vertical groove and can swing in the cavity. When the guide plate is stabilized by the lateral wind, it will drive the turntable to rotate, so that the counterweight liquid in the turntable flows in the flow cavity, and the turntable falls to the end of the lifting plate away from the windward surface. The weight of the entire turntable and the counterweight liquid can make the entire device subject to a force in the opposite direction, offsetting the tilting movement tendency of the device under the action of the lateral wind resistance, reducing the swing amplitude of the goods, and ensuring that the goods can be neatly stacked with the goods on the ground during the descent.

DETAILED DESCRIPTION

[0022] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] Example 1

[0024] like Figure 1-3 As shown, a windproof crane alignment device includes a horizontally arranged lifting plate 1, and a vertically arranged transmission box 2 is fixedly connected to the side walls around the lifting plate 1. A plurality of driving gears 3 are rotatably connected in the transmission box 2, and a driven gear 4 meshing with the driving gear 3 is provided at the lower end of each driving gear 3, and the plurality of driven gears 4 are rotatably connected to the inner side wall of the transmission box 2.

[0025] A friction layer 5 is fixedly connected to the side wall of the driven gear 4 which is close to the inner wall of the transmission box 2. When the friction layer 5 on the side wall of the driven gear 4 rotates relative to the inner wall of the transmission box 2, the frictional heat will cause the evaporative liquid in the transmission box 2 to evaporate. The elastic layer 7 on the side wall of the transmission box 2 bulges outward under the action of air pressure, which greatly reduces the wind resistance on the outer wall of the transmission box 2 facing the windward side, thereby reducing the amplitude of the shaking of the goods in the air.

[0026] The rotating shaft of each driving gear 3 extends to the outside of the transmission box 2 and is fixedly provided with a fan 6, which will rotate under the blowing of wind. An elastic layer 7 is fixedly embedded on the outer wall of each transmission box 2. The elastic layer 7 bulges to greatly reduce the wind resistance of the outer wall of the transmission box 2 facing the windward side, thereby reducing the shaking amplitude of the goods in the air.

[0027] A windproof mechanism and a gravity adjustment mechanism are respectively provided at the lower end and inside of the lifting plate 1. Specifically, the windproof mechanism includes a horizontal plate 8 slidably connected between the multiple transmission boxes 2. A plurality of elastic bellows 9 containing evaporative liquid are fixedly connected between the horizontal plate 8 and the lower side wall of the lifting plate 1. When the temperature reaches the boiling point of the evaporative liquid, the evaporative liquid will absorb heat and vaporize. The plurality of elastic bellows 9 are connected to the plurality of transmission boxes 2 through a conduit 10.

[0028] The gravity adjustment mechanism includes a cavity 11 opened inside the lifting plate 1, in which a rotating column 12 is rotatably connected, and the upper end of the rotating column 12 extends to the outside of the cavity 11 and is fixedly connected to a guide plate 13, and a rotating disk 14 is fixedly sleeved outside the rotating column 12, and a counterweight block 15 is fixedly embedded on the rotating disk 14.

[0029] The present invention can be explained by the following operation mode:

[0030] When the present invention is in use, the evaporative liquid is normally in the multiple elastic bellows 9. When lifting goods, the goods are fixed in the space surrounded by the multiple transmission boxes 2 and the lifting plate 1, and the horizontal plate 8 will be against the upper end of the goods. During the descent of the device, the multiple elastic bellows 9 will be compressed, and the evaporative liquid therein will be squeezed into the transmission box 2 through the conduit 10, which plays the role of automatically injecting the evaporative liquid. After use, when the goods are unloaded from the device, the evaporative liquid will return to the elastic bellows 9 under the suction of the elastic bellows 9, and can play a good containing role again.

[0031] When the entire device drives the goods up to a high altitude, the multiple fans 6 on the windward side will drive the driving gear 3 in the transmission box 2 to rotate under the blowing of the lateral wind, and drive the driven gear 4 meshing with it to rotate. The friction layer 5 on the side wall of the driven gear 4 will rotate relative to the inner wall of the transmission box 2. The frictional heat will cause the evaporative liquid in the transmission box 2 to evaporate, so that the elastic layer 7 on the side wall of the transmission box 2 will bulge outward under the action of air pressure, so that the wind resistance on the outer wall of the transmission box 2 facing the windward side is greatly reduced, thereby reducing the swaying amplitude of the goods in the air and ensuring that the goods can be neatly stacked with the goods on the ground during the descent.

[0032] When the cargo is blown by the lateral wind, the guide plate 13 at the upper end of the lifting plate 1 will stabilize in the direction with the least wind resistance. During the stabilization process, the turntable 14 will be driven to rotate in the cavity 11 through the rotating column 12, and the counterweight block 15 on the turntable 14 will be rotated to the end of the lifting plate 1 away from the windward side. The entire device is subjected to a force in the opposite direction through the gravity of the counterweight block 15 itself, offsetting the tilting movement trend of the device under the action of the lateral wind resistance, further reducing the swing amplitude of the cargo, and ensuring that the cargo can be neatly stacked with the cargo on the ground during the descent.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
