Description

Technical Field

[0001] The present invention relates to the field of hoisting equipment, in particular to modular unit hoisting equipment. Background Art

[0002] Hoisting refers to the use of a crane or lifting mechanism to lift equipment, workpieces, materials, etc. to a high place and then install them. Therefore, hoisting equipment is indispensable in the hoisting process, and the most common hoisting equipment in the existing technology is the crane.

[0003] There are many types of cranes, including crawler cranes and truck cranes. The roads at construction sites are mostly dirt roads covered with bricks and stones and are uneven. Therefore, crawler cranes with strong passability are often used, such as a construction crane with publication number CN208120608U.

[0004] During use, heavy objects are lifted to a high place by the crane's boom, so the crawler vehicle body on the ground needs to remain stable. In the existing technology, stability is generally improved by adding heavy objects to the crawler vehicle on the ground, but the weight that can be added is definitely limited. Therefore, the stability of the existing lifting equipment needs to be further improved.

[0005] In addition, when a crawler vehicle needs to turn during driving, generally one side of the crawler works, and the crawler on the other side rotates in place as the crawler vehicle turns. Therefore, the crawler rotating in place will produce serious friction with the ground, which will not only damage the ground, but also cause wear on the crawler itself. Summary of the Invention

[0036] (3) Beneficial effects

[0037] Compared with the prior art, the present invention provides a modular unit lifting device with the following features:

[0038] Beneficial effects:

[0039] 1. By filling the water tank with water, the weight of the water is used to increase the load of the crawler vehicle on the ground, so that the equipment is more stable when lifting heavy objects. Moreover, using water as a weight makes it more convenient to increase or reduce the load, and there is no need to perform heavy and complicated installation, disassembly and transportation like traditional heavy objects.

[0040] 2. The push platform is pushed backward by the electric slide rail, which drives the water tank backward. Then the telescopic mechanism is used to further move the water tank backward. The water tank has a certain weight. Moving it backward increases the lever arm of the counterweight mechanism, making it less likely for the weight of the heavy object to cause the equipment to overturn or tip over, thereby improving the stability of the equipment. There is no need to blindly add heavy objects to the equipment as in traditional methods.

[0041] 3. By installing raised parts on the crawler tracks of the crawler vehicle, when one of the crawlers rotates in place due to the turning of the crawler vehicle, the balls on the crawler track can contact and roll with the ground, thereby converting the sliding friction between the crawler track and the ground in the prior art into rolling friction between the balls and the ground, thereby reducing the wear on the ground and the crawler track itself.

[0042] 4. Hang the rope on the second elastic anti-sliding block at the top of the lower pressing block, and then use the hydraulic cylinder to push the upper pressing block downward so that the first elastic anti-sliding block on the upper pressing block is also in close contact with the rope. The first elastic anti-sliding block and the second elastic anti-sliding block are elastic and non-slip, and can clamp the rope to prevent it from moving relative to the hook unit and generating friction, thereby preventing the rope from breaking.

[0059] To facilitate understanding of the technical means, creative features, objectives, and effects achieved by the present invention, the present invention will be further described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0060] In order to address the shortcomings of existing technologies, such as Figure 1-15 As shown, the present invention provides a modular unit lifting device, including a crawler vehicle 1, a rotating platform 3 capable of adjusting direction is installed on the top of the crawler vehicle 1, a driver's cabin 2 and a lifting mechanism for lifting heavy objects are fixed on the top of the rotating platform 3, and a plurality of protruding parts 44 are installed on the crawler track of the crawler vehicle 1;

[0061] The raised component 44 includes a control box 4401 fixed on the crawler track. A panel 4402 is fixed to the top of the control box 4401 via bolts. A plurality of balls 4403 are embedded in the panel 4402. The balls 4403 pass through the panel 4402.

[0062] A push plate 4404 is provided inside the control box 4401. An anti-slip pad 4405 is fixed to the side of the push plate 4404 facing the ball 4403. A plurality of springs 4408 are fixed to the side of the push plate 4404 away from the ball 4403. One end of the spring 4408 is fixed to the inner wall of the control box 4401.

[0063] An iron sheet 4407 is fixedly provided on one side of the push plate 4404 away from the ball 4403 , and an electromagnet 4406 is fixedly provided on the inner wall of the control box 4401 , and the magnetic force of the electromagnet 4406 is used to attract the iron sheet 4407 .

[0064] When the crawler vehicle 1 needs to turn, one of the crawler tracks of the crawler vehicle 1 is stationary, and the other crawler track starts to move, thereby rotating the crawler vehicle 1 to the side where the crawler track is stationary. At this time, the raised part 44 on the stationary crawler track is controlled, and the electromagnet 4406 of the raised part 44 on the crawler track is energized. The electromagnet 4406 thus generates magnetic force and attracts the iron sheet 4407, causing the push plate 4404 to move, and the spring 4408 is compressed. After the push plate 4404 moves, the anti-slip pad 4405 also moves and aligns with the ball bearing 4408. 3 is separated, so that the ball 4403 loses its restriction and can rotate freely. At this time, the stationary track rotates in place under the drive of the other track, thereby causing the entire tracked vehicle 1 to start rotating, thereby turning. The track rotating in place contacts the ground through the ball 4403. Therefore, during the rotation process, the sliding friction between the track and the ground in the prior art is converted into rolling friction between the ball 4403 and the ground through the rolling of the ball 4403, thereby reducing the wear on the ground and the track itself.

[0065] When the ball 4403 is not needed in daily situations, the electromagnet 4406 is in a power-off state. At this time, the elastic force of the spring 4408 pushes the push plate 4404 and makes the anti-slip pad 4405 in close contact with the ball 4403, thereby limiting the rotation of the ball 4403. Therefore, when it is not needed, the ball 4403 cannot rotate. Since the rolling between the ball 4403 and the ground is required to reduce the friction between the track and the ground, the above method is suitable for hard ground, such as brick and stone ground and dry and hard mud ground, etc., but is not suitable for soft ground, such as sand and water-soaked mud ground.

[0066] To facilitate the change of weight, such as Figure 1 、 2 As shown in Figures 3 and 4, a counterweight mechanism is provided on one side of the lifting mechanism, and the counterweight mechanism includes a water tank 16 on the top of the rotating platform 3. One end of the water tank 16 extends to the rear side of the crawler vehicle 1. A counterweight plate 24 capable of loading heavy objects is provided on the rear side of the crawler vehicle 1. Two universal wheels 43 are installed at the bottom end of the counterweight plate 24, and two support columns 25 connected to the water tank 16 are fixed on the top of the counterweight plate 24.

[0067] Embodiment one

[0068] In the process of hoisting with the device, water can be injected into the water tank 16, and the weight of the water is used to increase the load of the track vehicle 1 on the ground, so that the device is more stable when lifting the load, and the water is used as the weight, which can be directly discharged when not needed, and it is more convenient to increase or reduce the load, without the heavy and complex installation, disassembly and transportation of the traditional weight.

[0069] In order to further improve the stability of the device, as shown in Figure 1 、 2 , 3, 4, 12, the bottom end of the water tank 16 is fixedly provided with a sliding table mounted on the rotating platform 3, which includes an extension plate 28 at the bottom of the water tank 16 and clamping plates 41 clamped on both sides of the extension plate 28, the clamping plates 41 are fixedly provided at the bottom end of the water tank 16, and the extension plate 28 extends to the front side of the water tank 16 and is fixedly provided with a pushing table 23 at the front end, the pushing table 23 is mounted at the top end of the rotating platform 3 through an electric sliding rail, and is used to push the water tank 16 to move backward.

[0070] The top end of the pushing table 23 is fixedly provided with a vertical plate 6, the rear side of the vertical plate 6 is provided with a sleeve 12, the top end of the water tank 16 is fixedly provided with a mounting plate 13, the rear side of the mounting plate 13 is fixedly provided with a first motor 14, the front side of the mounting plate 13 is provided with a threaded rod 27 through a bearing, one end of the threaded rod 27 penetrates through the mounting plate 13 and is fixedly connected with the output shaft of the first motor 14, the other end of the threaded rod 27 extends into the sleeve 12 and is connected with the inner wall of the sleeve 12 through a thread, and the sleeve 12 and the threaded rod 27 constitute an extension mechanism, which is used to further push the water tank 16.

[0071] The rear side of the water tank 16 is fixedly provided with a water pipe 40 with a valve, so as to inject water into the water tank 16 and drain water, and the front side of the water tank 16 is provided with an inspection door 26 through a hinge, and the top end of the water tank 16 is fixedly provided with an air pipe for balancing air pressure.

[0072] The rear side of the vertical plate 6 is provided with a mounting disc 42 through bolts, and the mounting disc 42 is fixedly provided at the outer end of the sleeve 12, so as to realize the disassembly of the sleeve 12.

[0073] Embodiment two

[0074] While water is being poured into the water tank 16, heavy objects can be placed on the counterweight plate 24 in the same way as in the traditional way, which assists the water tank 16. Moreover, the counterweight plate 24 is close to the ground, making it more convenient to place heavy objects. In addition, the pushing platform 23 can be pushed backward by the electric slide rail, thereby pushing the water tank 16 backward, and the universal wheel 43 rolls on the ground to separate the water tank 16 from the rotating platform 3. After the pushing platform 23 moves into place, the first motor 14 is turned on to drive the threaded rod 27 to rotate. The threaded rod 27 is connected to the sleeve 12 by a thread, so that the threaded rod 27 extends backward from the sleeve 12 after rotation, further pushing the water tank 16 backward, and the clamping plate 41 also extends backward from the extension plate 28, thereby utilizing the telescopic mechanism to further move the water tank 16 backward, so that the water tank 16 is completely in a separated state.

[0075] The lifting mechanism and the heavy object it lifts are located on the front side of the rotating platform 3. The gravity of the heavy object presses the lifting mechanism downward, and the bottom end of the lifting mechanism is connected to the rotating platform 3 and the tracked vehicle 1 to form a lever. Therefore, the lever may cause the rotating platform 3 and the tracked vehicle 1 to overturn from back to front. At this time, the water tank 16 is located as a whole on the rear side of the rotating platform 3 and is also connected to the rotating platform 3 and the tracked vehicle 1, also forming a lever. The water tank 16 has a certain weight because it is filled with water. This weight presses the rotating platform 3 and the tracked vehicle 1 downward to prevent them from overturning forward, and the water tank 16 moves backward, increasing the lever arm of the gravity of the water tank 16, so that the lever formed by the water tank 16 has a greater downward force, and thus the lever formed by the heavy object and the lifting mechanism has a greater resistance. Therefore, the weight of the heavy object is not likely to cause the equipment to overturn or tip over, thereby improving the stability of the equipment and eliminating the need to blindly add heavy objects to the equipment as in the traditional way.

[0076] The water tank 16 can move on the ground under the action of the universal wheel 43. Therefore, the rotating platform 3 rotates around the center of the rotating platform 3 during operation, which will cause the water tank 16 and the lifting mechanism to rotate accordingly. Therefore, the position of the water tank 16 lifting mechanism relative to the rotating platform 3 and the tracked vehicle 1 remains unchanged. However, as the distance between the water tank 16 and the tracked vehicle 1 increases, the rotation radius of the water tank 16 will expand. This requires that the lifting equipment has a larger operating space when performing the above operations.

[0077] The distance that the water tank 16 can move is limited. Figure 3 、 10 As shown, a winding drum 4 is installed on the top of the rotating platform 3 through a support. The winding drum 4 is located in front of the pushing platform 23. A drum door is installed on the outer end of the winding drum 4 through a hinge.

[0078] A fixed shaft 37 is provided inside the winding drum 4. The two ends of the fixed shaft 37 are movably connected to the inner walls of the winding drum 4 on both sides through bearings. A spring 39 is installed at both ends of the fixed shaft 37. The two ends of the spring 39 are fixedly connected to the outer end of the fixed shaft 37 and the inner wall of the winding drum 4, respectively, to drive the fixed shaft 37 to rotate.

[0079] A partition 38 that serves as a partition is fixed to the outer end of the fixed shaft 37. Two anti-slip ropes 29 are fixed to the outer end of the fixed shaft 37 and the anti-slip ropes 29 are wound around the outer end of the fixed shaft 37. The two anti-slip ropes 29 are respectively arranged on both sides of the partition 38. One end of the anti-slip rope 29 extends to the outside of the winding drum 4 and is fixedly connected to the water tank 16, so as to limit the moving distance of the water tank 16.

[0080] When the water tank 16 moves back, the elastic force of the clockwork spring 39 will drive the fixed shaft 37 to rotate, and the anti-offline rope 29 will be retracted into the reel 4.

[0081] Heavy objects need to be lifted by a lifting mechanism, such as Figure 1 、 5 As shown in Figures 11, the lifting mechanism includes a support module and a tension module. The support module includes a fixed seat 20 fixed to the top of the rotating platform 3. A telescopic boom 11 is provided on the top of the rotating platform 3. The bottom end of the telescopic boom 11 is hinged to the fixed seat 20 and is movably installed on the top of the rotating platform 3. A boom bracket 32 ​​is fixed to the top of the telescopic boom 11.

[0082] The boom bracket 32 ​​is internally provided with a limiting roller 31 and a supporting roller 30 with a notch on the surface. The ends of the supporting roller 30 and the limiting roller 31 are respectively movably connected to the inner walls of the two sides of the boom bracket 32 ​​through a rotating shaft. The outer end of the telescopic boom 11 is provided with a fall arrester 10 that plays an anti-falling role. The fall arrester 10 with a length of 10 meters to 20 meters can be selected. The bottom end of the fall arrester 10 is connected to the heavy object. If the heavy object falls and falls at high speed, the fall arrester 10 will be pulled and locked to prevent the heavy object from falling to the ground, thereby improving the safety of the equipment.

[0083] An adjustment seat 22 is provided at the top of the rotating platform 3 through an electric slide rail, and a support arm 21 is provided at the top of the adjustment seat 22 for supporting. The two ends of the support arm 21 are respectively hinged to the outer end of the telescopic boom 11 and the top of the adjustment seat 22.

[0088] The hook unit 7 and the adjustment unit 8 used to connect with the heavy object are both installed at the top of the telescopic boom 11. The telescopic boom 11 has a telescopic function so that the heavy object can be lifted to a higher position for installation. The hook unit 7 is directly connected and fixed to the heavy object. The angle of the hook unit 7 when connected to the heavy object is controlled by the adjustment unit 8. The hook unit 7 is connected to the outer end of the fixed rod 804 through the connecting block 806, and the fixed rod 804 can rotate inside the bogie 805, thereby driving the hook unit 7 to rotate, so that the angle between the hook unit 7 and the horizontal plane changes, which is convenient for hanging the heavy object on the hook unit 7, and also for separating the heavy object from the hook unit 7. At the same time, the adjusting shaft 807 can be rotated to drive the bogie 805 and the hook unit 7 to rotate horizontally as a whole, further adjust the angle of the hook unit 7, and improve the flexibility of the hook unit 7.

[0089] In order to avoid the rope on the heavy object from breaking due to friction, Figure 6-8 As shown, the hook unit 7 includes a mounting box 701, the bottom end of the connecting block 806 is fixedly connected to the top end of the mounting box 701, and a closing plate 708 is fixed to one side of the mounting box 701 by screws to facilitate disassembly and maintenance;

[0090] Two hydraulic cylinders 702 are installed inside the installation box 701. The piston rods of the hydraulic cylinders 702 extend to the bottom of the installation box 701. A hook 703 capable of hanging heavy objects is fixed at the bottom of the installation box 701.

The first elastic anti-slip block 706 and the second elastic anti-slip block 707 clamp the rope on the heavy object.

[0092] Example 3

[0093] Generally speaking, heavy objects that need to be hoisted on construction sites, such as beams and columns of steel structures, cannot be connected to the hook unit 7 by themselves. It is necessary to tie a rope to the heavy object and then hang the rope on the hook unit 7 for hoisting. In the existing technology, the rope is directly hung on the hook of the hoisting equipment. During the hoisting process, the rope will move relative to the hook and generate friction. In addition, the rope itself is subjected to a large force, which can easily cause the rope to break.

[0094] Therefore, the hoisting device is bolted with the lower pressing block 705 on the hook body 703, the rope is hung at the second elastic anti-skid block 707 at the top end of the lower pressing block 705, and then the upper pressing block 704 is pushed downward by the hydraulic cylinder 702, so that the first elastic anti-skid block 706 on the upper pressing block 704 also tightly contacts the rope. When the rope is extruded by the first elastic anti-skid block 706 and the second elastic anti-skid block 707, the two will be deformed, and a space capable of accommodating the rope is generated between the two. The first elastic anti-skid block 706 and the second elastic anti-skid block 707 are elastic and anti-skid, can clamp the rope, avoid relative movement between the hook unit 7 and the rope to generate friction, and thus avoid the rope from being broken. In addition, the upper pressing block 704 and the lower pressing block 705 can be replaced according to the different ropes or the wear condition.

[0095] The weight of the weight is mainly borne by the tension module, such as Figure 1 、 5 , 6, 9, 11, the tension module is arranged at the rear side of the winding drum 4, the tension module includes a fixed frame 19 fixed at the top end of the rotating platform 3, one side of the fixed frame 19 is fixedly provided with a second motor 18, the inner side of the fixed frame 19 is provided with a center shaft 35, the two ends of the center shaft 35 are respectively movably connected with the inner walls of the two sides of the fixed frame 19 through shafts, and one end of the center shaft 35 extends to one side of the fixed frame 19 and is fixedly connected with the output shaft of the second motor 18;

[0096] A plurality of steel wires 9 are fixedly arranged at the outer end of the center shaft 35, the fixed frame 19 is driven to rotate by the second motor 18 to pull the steel wires 9, the steel wires 9 are wound around the outer end of the center shaft 35, one end of the steel wires 9 extends to the supporting roller 30, the steel wires 9 extend downward from the outer end of the supporting roller 30 after winding around the supporting roller 30 from the top of the supporting roller 30, and the limiting roller 31 limits the steel wires 9 at the outer end of the supporting roller 30.

[0097] The steel wires 9 extend to the bottom of the supporting roller 30 and then wind around the adjusting roller 801 from the bottom end of the adjusting roller 801, and the steel wires 9 are embedded in the gaps at the outer ends of the supporting roller 30 and the adjusting roller 801, thereby improving the stability of the steel wires 9.

[0098] The steel wires 9 extend upward after winding around the adjusting roller 801, a back-shaped rod 33 is fixedly arranged at the top end of the telescopic lifting arm 11, a fixed sleeve 34 is sleeved on the outer end of the back-shaped rod 33, and one end of the steel wires 9 is connected with the outer end of the fixed sleeve 34.

[0099] ​One end of the wire rope 9 is wound and fixed on the central shaft 35, and the central shaft 35 is driven to rotate by the second motor 18 to tighten or loosen the wire rope 9. The other end of the wire rope 9 passes around the outer end of the support drum 30 to form a fixed pulley structure, and then passes around the bottom end of the adjusting drum 801 and is connected to the fixed sleeve 34 to form a movable pulley structure. Therefore, the tension module forms a pulley group at one end of the telescopic boom 11, which is used to lift heavy objects. When the wire rope 9 is tightened, it will pull the adjusting unit 8 and the hook unit 7 upward to lift the heavy object, and vice versa, it will put the heavy object down.

[0100] In order to make the wire rope 9 run more smoothly, Figure 1 、 9 As shown, a plurality of baffles 36 are fixedly provided at the outer end of the central shaft 35, and the baffles 36 are used to separate each steel wire rope 9 from each other to prevent them from being entangled with each other;
