Description

Technical Field

[0001] This utility model relates to the field of boom lifting machine manufacturing technology, specifically a single-layer self-winding boom lifting machine that is easy to move. Background Technology

[0002] Electric hoisting systems are an essential piece of equipment on modern stages. A hoisting system is a small, horizontal pole that can be raised and lowered parallel to the proscenium. Electric hoists come in various drive types, such as single-slot hoists, four-slot hoists, large-diameter double-enclosed hoists, and multi-point hoists. They are used to suspend curtains, soft scenery, lighting fixtures, etc. In stage performances, many curtains need to be suspended. The hoisting stroke is generally from about 0.5 meters below the top of the stage to about 1.5 meters above the stage surface.

[0003] A search revealed Chinese patent CN218665146U, which discloses a single-layer self-aligning rope hoisting machine. This machine includes a base plate with a rectangular hole inside. A moving mechanism is connected to the inner side of the rectangular hole. The moving mechanism includes a second round rod, a locking rod, a third round rod, a connecting block, a slotted block, and rollers. In use, the base plate is lifted, and the connecting block is rotated downwards until it is vertical. The locking rod is then moved along the second round rod to its foremost point. The locking rod is then rotated downwards around the second round rod until the end of the locking rod away from the second round rod is level with the inner side of the slotted block. The locking rod is then moved backwards along the second round rod until the end of the locking rod away from the second round rod engages with the inner side of the slotted block. At this point, the connecting block and the rollers below it stably and firmly support the base plate.

[0004] Although the above-mentioned utility model can move the position of the boom lifter, it requires the operator to lift the base plate and manually rotate the angles of the four levers and rollers, which greatly increases the labor intensity of the operator and reduces work efficiency.

[0007] The switching mechanism includes a support frame located on the outside of the base plate. Two mounting brackets are fixed at both ends of the upper surface of the base plate. A cylinder is fixed in the inner cavity of the mounting bracket. The piston rod of the cylinder passes through the mounting bracket and extends to the lower surface of the mounting bracket and is fixed to the support frame. Limit blocks are fixed at the top of the opposite side of the left and right side walls of the inner cavity of the support frame. Limit grooves are opened on both the left and right sides of the support frame.

[0008] Furthermore, the number of the four casters is evenly distributed on the left and right ends of the lower surface of the base plate.

[0009] Furthermore, the length and width of the inner cavity of the support frame are both greater than the length and width of the base plate, and the number of mounting brackets is four and they are evenly distributed on the left and right ends of the upper surface of the base plate.

[0010] Furthermore, the mounting bracket has an inverted L-shaped cross-section, the support frame moves vertically up and down on the outside of the base plate, and the limiting block moves vertically up and down within the limiting groove.

[0011] Furthermore, the rope-pulling mechanism includes two mounting plates fixed to the left and right front ends of the upper surface of the base plate. A screw is rotatably connected between the two mounting plates on opposite sides via bearings. The right ends of the rope-winding roller and the screw respectively penetrate and extend to the right side of the right-end fixed plate and the right side of the right-end mounting plate, and the rope-winding roller and the screw are connected by belt drive. A drive motor is fixed to the right side of the right-end mounting plate. A threaded sleeve is threaded onto the outer surface of the screw. A fixing frame is fixed to the upper surface of the threaded sleeve.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This embodiment of a movable single-layer self-winding rope hoist includes a base plate 1. Universal wheels 2 are fixed to both ends of the lower surface of the base plate 1. A switching mechanism 3 for facilitating the movement of the hoist is provided on the outer side of the base plate 1. Fixed plates 4 are fixed to the rear ends of both ends of the upper surface of the base plate 1. A rope winding roller 5 is rotatably connected between the opposite sides of the two fixed plates 4 through a bearing. A rope pulling mechanism 6 is provided at the front ends of both ends of the upper surface of the base plate 1.

[0024] In this embodiment, there are four casters 2, which are evenly distributed on the left and right ends of the lower surface of the base plate 1. With the four evenly distributed casters 2, the boom crane can move on different terrains, which improves the flexibility and portability of the boom crane.

[0025] Please see Figures 2 to 3 To facilitate the movement of the boom crane, the switching mechanism 3 in this embodiment includes a support frame 301 located on the outer side of the base plate 1. Two mounting brackets 302 are fixed to both the left and right ends of the upper surface of the base plate 1. A cylinder 303 is fixed inside the inner cavity of each mounting bracket 302. The piston rod of the cylinder 303 passes through the mounting bracket 302 and extends to its lower surface, where it is fixed to the support frame 301. The boom crane can be moved to the target area via four casters 2 on the lower surface of the base plate 1. Then, the four cylinders 303 are activated, causing their piston rods to move downwards and further push... The moving support frame 301 moves downward. Limiting blocks 304 are fixed on the top of the opposite side of the left and right side walls of the inner cavity of the support frame 301. Limiting grooves 305 are opened on both the left and right sides of the support frame 301. The movement of the support frame 301 drives multiple limiting blocks 304 to move downward in the inner cavity of the limiting grooves 305 until the support frame 301 moves to contact the ground. The limiting blocks 304 move to the lowest point in the limiting grooves 305, thereby lifting the casters 2. The support frame 301 supports the base plate 1, ensuring the stability of the boom crane during operation.

[0026] In this embodiment, the length and width of the inner cavity of the support frame 301 are both greater than the length and width of the base plate 1. There are four mounting brackets 302, which are evenly distributed on the left and right ends of the upper surface of the base plate 1. The cross-sectional shape of the mounting bracket 302 is an inverted L shape. The support frame 301 moves up and down in a straight line on the outside of the base plate 1, and the limiting block 304 moves up and down in a straight line in the inner cavity of the limiting groove 305.

[0027] It should be noted that the cylinder 303 drives the support frame 301 to move up and down, making it easy for workers to lift the boom machine during operation. The support frame 301 provides support, ensuring the stability of the boom machine during operation.

[0028] Please see Figure 4To facilitate neat winding and unwinding of the rope, the rope-pulling mechanism 6 in this embodiment includes two mounting plates 601 fixed to the front ends of the left and right sides of the upper surface of the base plate 1. A screw 602 is rotatably connected between the opposite sides of the two mounting plates 601 via bearings. The right ends of the winding roller 5 and the screw 602 respectively penetrate and extend to the right side of the right-end fixing plate 4 and the right-end mounting plate 601, and the winding roller 5 and the screw 602 are connected by a belt drive. One end of the rope on the winding roller 5 is passed through the opposite sides of the two guide wheels 606, and the drive motor 603 is started. The output shaft of the drive motor 603 rotates, driving the winding roller 5 to rotate. The rotation of the winding roller 5 can be achieved through belt drive... The screw 602 rotates, and the rotation of the rope winding roller 5 allows the rope to be wound off the rope winding roller 5. A drive motor 603 is fixed to the right side of the right end mounting plate 601. A screw sleeve 604 is threadedly connected to the outer surface of the screw 602. A fixing frame 605 is fixed to the upper surface of the screw sleeve 604. The left and right ends of the inner top wall and inner bottom wall of the fixing frame 605 are rotatably connected to guide wheels 606 through bearings. The rotation of the screw 602 causes the screw sleeve 604 threadedly connected to its surface to move linearly. The movement of the screw sleeve 604 drives the fixing frame 605 and the two guide wheels 606 to move, so that the rope wound off the rope winding roller 5 is neatly released under the traction of the two guide wheels 606.

[0029] In this embodiment, the output shaft of the drive motor 603 is fixed to the right side of the winding roller 5. The fixed frame 605 is a cuboid with a hollow interior and missing front and rear sides. A slide bar is fixed on the upper surface of the base plate 1, and a slider is fixed on the lower surface of the screw sleeve 604. The slider moves horizontally in the inner cavity of the slide bar. The slider and slide bar can limit the movement of the screw sleeve 604, so that the screw sleeve 604 can only move in a straight line.

[0030] Understandably, the automatic rope arrangement is achieved through the cooperation of the drive motor 603 and the screw 602, reducing manual intervention, improving work efficiency, and further reducing the labor intensity of workers. The design of the two guide wheels 606 makes the rope arrangement process smoother, ensuring that the rope can be neatly released from the winding roller 5.

[0031] The working principle of the above embodiments is as follows:

[0032] (1) The boom hoist can be moved to the target area by the four casters 2 on the lower surface of the base plate 1. Then, the four cylinders 303 are activated. The piston rods of the cylinders 303 move downward to further push the support frame 301 downward. The movement of the support frame 301 drives multiple limit blocks 304 to move downward in the inner cavity of the limit groove 305 until the support frame 301 moves to contact the ground. The limit blocks 304 move to the lowest point in the limit groove 305, thereby lifting the casters 2. The base plate 1 is supported by the support frame 301 to ensure the stability of the boom hoist during operation.

[0033] (2) Then, one end of the rope on the winding roller 5 is passed through the two guide wheels 606 on opposite sides, and the drive motor 603 is started. The output shaft of the drive motor 603 rotates, causing the winding roller 5 to rotate. The rotation of the winding roller 5 can cause the screw 602 to rotate through belt transmission. The rotation of the winding roller 5 can cause the rope to be wound off the winding roller 5. The rotation of the screw 602 causes the threaded sleeve 604 on its surface to move linearly under the action of the slider and the slide bar. The movement of the threaded sleeve 604 causes the fixed frame 605 and the two guide wheels 606 to move, so that the rope wound off the winding roller 5 is neatly released under the traction of the two guide wheels 606.
