Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a rope slipping device used for lifting and hoisting. Background Art

[0002] When hoisting heavy objects, the objects are lifted into the air by hoisting equipment, and then rotated, changed amplitude, and fell back in the air to complete the work of positioning the heavy objects. However, the position and posture of the hoisted heavy objects in the air will be affected by factors such as wind speed and external forces and will change to varying degrees, making it impossible to complete the hoisting smoothly according to the predetermined position and posture.

[0003] In order to solve the above problems, in the prior art, two or more safety ropes are usually tied to a certain part of the body of the hoisted heavy object to adjust the position and posture of the heavy object during the hoisting process so that the heavy object can be hoisted to the predetermined position. However, during the hoisting process, since the safety rope has a certain length, it is always in a state of being dragged by the hoisted heavy object during the hoisting process. If the rope is set too short, the construction personnel will not be able to touch the safety rope after the hoisted heavy object is lifted into the air, and thus will not be able to adjust the position and posture of the heavy object in time according to the hoisting requirements. When hoisting heavy objects, they are bound to pass over the top of the installed equipment or other building structures. It is easy for the safety rope to interfere with or entangle with the equipment and building structure, which seriously affects the safety and progress of the hoisting construction and causes the overall project to be unable to be completed on schedule. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a rope slip device for lifting and hoisting, which can freely adjust the length of the rope slip at any time to avoid interference or entanglement between the rope slip and the equipment or the building body during the lifting of heavy objects.

[0005] The utility model proposes a rope-slipping device for lifting and hoisting, comprising a shell suspended on a hoisted object, wherein a driving device and a drum are arranged in the shell, wherein one end of the drum is connected to an output end of the driving device, and the other end of the drum is arranged on a bearing seat in the shell, and a rope is wound around the drum; a rope head at a cable arrangement end of the rope passes through the shell and is connected to at least one handle; and the driving device is communicatively connected to a remote controller.

[0006] Preferably, the shell includes a first split body and a second split body, and the second split body is detachably connected to the first split body.

[0007] Preferably, the bearing seat for mounting the reel and a fixing bracket for mounting the driving device are fixedly disposed in the first sub-body, and the bearing seat and the fixing bracket are arranged opposite to each other.

[0008] Preferably, a wire arrangement hole is provided at the connection between the first sub-body and the second sub-body, and the wire arrangement hole is located below the reel, so that the rope end can pass through the wire arrangement hole and be connected to the handle.

[0009] Preferably, a limit device is provided at the wiring hole, and the limit device is electrically connected to the drive device through a control circuit; when the handle rises to the limit position, the handle contacts the limit device, causing the control circuit to cut off the power supply to the drive device.

[0010] Preferably, the ends of both ends of the reel are provided with limiting plates.

[0011] Preferably, a hanging point is provided on the top of the shell, and the hanging point is connected to the hoisted object through a sling.

[0012] Preferably, the handle is arranged in a triangular shape.

[0013] As described above, the utility model relates to a rope slipping device for lifting and hoisting, which has the following beneficial effects:

[0014] During hoisting, the rope-slipping device is hung on the hoisting object as a whole, and then the driving device is started by the remote control, so that the driving device drives the drum to rotate counterclockwise. At this time, the construction personnel can freely adjust the length of the handle to a suitable distance by pulling the handle downward, and then control the driving device to be closed by the remote control device to stop the drum from rotating. The utility model can effectively avoid interference or entanglement between the rope and the equipment and building structure at the hoisting site, and effectively improve the hoisting efficiency.

[0022] like Figure 1-Figure 3 As shown, the utility model provides an embodiment of a slip rope device for lifting and hoisting, including a housing 100 hung on the hoisting object, the housing 100 is arranged in a dome-shaped square base, a driving device 200 and a drum 300 are arranged in the housing 100, one end of the drum 300 is connected to the output end of the driving device 200, and the other end of the drum 300 is arranged on a bearing seat 400 in the housing, and a slip rope 310 is wound on the drum 300; the rope head of the slip rope arrangement end passes through the housing 200 and is connected to at least one handle 500, and the handle 500 includes but is not limited to a triangular shape, and can also be arranged in a rectangular or circular shape to meet the function of the operator to grasp and exert force, and the handle has the function of counterweight. The driving device 200 is connected to the remote control in communication. Among them, the driving device 200 includes a motor, a power supply 700 and a receiver 800, and the power supply 700 is connected to the motor and the receiver 800 through a control circuit, and the motor is preferably a hollow DC brake motor.

[0023] Furthermore, a hanging point 130 is provided on the top of the shell 100, and the hanging point 130 is connected to the hoisted object through a sling.

[0024] When in use, the rope slip device is hung on the hoisting object through the sling, and the construction personnel hold the remote control to release the motor start signal. The receiver 800 receives the signal and starts the motor through the control circuit. The motor drives the drum 300 to rotate counterclockwise, and the rope slip 310 on the drum 300 is discharged. Under the gravity of the handle 500, the rope slip 310 moves downward with the handle until the construction personnel standing on the ground can easily hold the handle 500, thereby effectively meeting the requirements of hoisting and adjusting the position and posture of the heavy object. It can meet the construction personnel's need to freely adjust the length of the rope slip 310 extending from the housing 100 at any time, and avoid the phenomenon of the rope slip interfering with or entangled with the equipment and building structure at the hoisting site. When the hoisting is completed, the construction personnel can control the motor to drive the drum 300 to rotate clockwise through the remote control, so that the drum 300 drives the rope slip 310 to rise until the handle 500 is close to the housing wall, and then control the motor to turn off, stop the drum 300 from closing, and store the rope slip 310 in the housing 100.

[0025] In one embodiment, the housing 100 includes a first body 110 and a second body 120. The first body 110 and the second body 120 are connected by a connection method including but not limited to a threaded connection, and a connection method such as a clamping connection or a hinge connection can also be selected to facilitate the later maintenance of the drive device, the reel and other components. The first body 110 is fixed with a bearing seat 400 for installing the reel 300 and a fixing bracket 111 for installing the drive device 200. The bearing seat 400 and the fixing bracket 111 are arranged opposite to each other. The bearing seat 400 and the fixing bracket 111 can be fixed to the first body 110 by bolt connection or welding.

[0026] In one embodiment, both ends of the drum 300 are provided with a limit plate 320, so that the slip rope 310 is located between the two limit plates 320, to prevent the slip rope 310 from detaching from the drum during the process of winding or arranging the line of the drum 300. The limit plate 320 located on the side where the drum 300 is connected to the motor is connected to the motor by a key connection.

[0027] In one embodiment, a cable hole 112 is provided at the connection between the first body 110 and the second body 120, and the cable hole 112 is located below the drum 300, so that the end of the slip rope can pass through the cable hole 112 and connect with the handle 500. When in use, the drum 300 rotates clockwise or counterclockwise to drive the slip rope 310 to freely rise and fall along the cable hole 112 to meet the needs of construction workers for lifting.

[0028] In one embodiment, a limit device 600 is provided at the cable hole 112, and the limit device 600 is electrically connected to the drive device 200 through a control circuit. When the handle 500 rises to the limit position, the handle 500 contacts the limit device 600, causing the control circuit to cut off the power supply to the drive device.

[0029] Specifically, the limit device 600 includes but is not limited to a spring-type limiter, which includes a spring and a limiter, the spring starts from the outside of the cable hole 112, the spring is connected to the limiter, the limiter is connected to the control circuit, and the slip rope 310 passes through the spring. When in use, after the hoisting is completed, the drum 300 rotates clockwise to drive the slip rope 310 and the handle 500 to rise, and when the handle 500 compresses the spring, the limit switch in the limiter is triggered to disconnect, thereby cutting off the power supply of the motor, so that the drum 300 stops rotating, thereby preventing the handle 500 from hitting the top.

[0030] In summary, the utility model can effectively prevent the slip rope from interfering with or entangled with the equipment and building structure at the hoisting site, thereby effectively improving the hoisting efficiency.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
