Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical engineering, in particular to a steel wire rope storage structure for an elevator crane. Background Art

[0002] An elevator crane is a mechanical device used for material transportation and lifting operations at construction sites or factories. The elevator crane has the functions of transportation and lifting, which not only saves construction costs but also improves construction efficiency. At the same time, it has high safety performance and can ensure the safety of personnel during the construction process. A wire rope elevator crane is an elevator crane that relies on wire rope for transmission.

[0003] At present, the wire rope is generally wound and stored by driving an I-shaped roller with a motor. During this process, the wire rope can only be stored, and the wire rope cannot be oiled and maintained. Workers need to manually oil and maintain it, and uneven oiling will occur. At the same time, when the elevator crane stops at a certain floor, the I-shaped roller will cause the output shaft of the drive motor to generate a certain torque under the action of the wire rope tension, so that the output end of the drive motor will always be under force when the elevator crane stops, affecting the service life of the drive motor. Based on this, a wire rope storage structure for an elevator crane is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a steel wire rope storage structure for an elevator crane to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire rope storage structure for an elevator crane, comprising a base plate and a winding drum, fixed plates are installed on both sides of the upper end of the base plate, a connecting shaft is rotatably connected between the two fixed plates, the winding drum is installed on the surface of the connecting shaft between the fixed plates, a driving motor is installed on the upper end of the base plate on one side of the fixed plate, the output end of the driving motor is connected to the connecting shaft, a locking assembly is installed on the connecting shaft, a moving block is movably installed between the two fixed plates in front of the winding drum, the lower end of the moving block is rotatably connected to an oiling wheel, an oil box is installed at the front end of the moving block, and an oil filling pipe is installed at the lower end of the oil box just above the oiling wheel.

[0006] Preferably, the locking assembly includes a fixed frame, an electric push rod, a movable plate, a locking plate and a locking gear. The upper ends of the two fixed plates are jointly equipped with a fixed frame, the lower end of the fixed frame is equipped with an electric push rod, the output end of the electric push rod is equipped with a movable plate, locking plates are installed on both sides of the lower end of the movable plate, the surface of the connecting shaft below the locking plate is equipped with a locking gear, and the lower end of the locking plate is provided with a locking groove.

[0007] Preferably, a fixing block is installed at one end of the fixing plate away from the winding drum, a movable groove is arranged through the upper end of the fixing block, and the locking plate is slidably installed inside the movable groove.

[0008] Preferably, a wire arrangement wheel is movably installed between the two fixed plates in front of the winding drum.

[0009] Preferably, two polished rods are installed between the two fixed plates at the rear of the wire traversing wheel, the two polished rods are located between the wire traversing wheel and the winding drum, and the moving block is installed on the surfaces of the two polished rods through through holes.

[0010] Preferably, a sealing cap is threadedly connected to the upper end of the oil box, and an adjusting head is installed on the oil filling pipe.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The steel wire rope storage structure for the elevator crane is equipped with components such as an oiling wheel, an oil box and an oil pipe. When the steel wire rope is wound and unwound, the oil inside the oil box flows through the oil pipe to the surface of the oiling wheel. The steel wire rope contacts the oiling wheel, and the steel wire rope drives the oiling wheel to rotate, thereby achieving oiling of the steel wire rope without the need for workers to oil the wire rope. The oiling effect is good, and the waste of oil is effectively reduced.

[0013] 2. This wire rope storage structure for elevator cranes is equipped with a locking assembly. When the elevator crane car stops, the electric push rod in the locking assembly extends to drive the movable plate to move. The movable plate causes the locking groove on the locking plate to contact the locking gear, thereby locking the locking gear. This effectively prevents the torque generated by the winding drum from being transmitted to the output end of the drive motor, thereby extending the service life of the drive motor.

[0020] like Figures 1 to 3 As shown, the steel wire rope storage structure for elevator cranes in this embodiment includes a base plate 1 and a winding drum 2. Fixed plates 3 are installed on both sides of the upper end of the base plate 1. A connecting shaft 4 is rotatably connected between the two fixed plates 3. The winding drum 2 is installed on the surface of the connecting shaft 4 between the fixed plates 3. A driving motor 5 is installed on the upper end of the base plate 1 on one side of the fixed plate 3. The output end of the driving motor 5 is connected to the connecting shaft 4. The winding drum 2 is driven by the driving motor 5 to rotate, so that the winding drum 2 can reel in and unreel the steel wire rope of the elevator crane. A locking component is installed on the connecting shaft 4. The locking component is used to lock the connecting shaft 4. The rotation of the winding drum 2 is locked, which effectively prevents the torque received by the winding drum 2 from being transmitted to the output shaft of the driving motor 5. A moving block 7 is movably installed between the two fixed plates 3 in front of the winding drum 2. The moving block 7 drives the oiling wheel 8 to move with the wire rope. The lower end of the moving block 7 is rotatably connected to the oiling wheel 8. An oil box 9 is installed at the front end of the moving block 7. The lower end of the oil box 9 is located just above the oiling wheel 8 and an oil filling pipe 10 is installed. The oil inside the oil box 9 flows into the oiling wheel 8 through the oil filling pipe 10. The oiling wheel 8 is in contact with the wire rope, and the wire rope drives the oiling wheel 8 to rotate, thereby realizing the oiling maintenance of the wire rope.

[0021] 605 .

[0022] Furthermore, a fixed block 12 is installed at one end of the fixed plate 3 away from the winding drum 2, and a movable groove 13 is arranged through the upper end of the fixed block 12. The locking plate 604 is slidably installed inside the movable groove 13. The setting of the movable groove 13 serves as a guide for the movement of the locking plate 604, and at the same time effectively prevents the torque generated by the locking gear 605 from being transmitted to the movable plate 603.

[0023] Furthermore, a wire arrangement wheel 14 is movably installed between the two fixed plates 3 in front of the winding drum 2. The arrangement of the wire arrangement wheel 14 is used to ensure that the wire rope is neatly arranged on the winding drum 2.

[0024] Furthermore, two polished rods 15 are installed between the two fixed plates 3 at the rear of the wire arranging wheel 14. The two polished rods 15 are located between the wire arranging wheel 14 and the winding drum 2. The movable block 7 is installed on the surface of the two polished rods 15 through a through hole. The wire rope contacts the oiling wheel 8 and the wire arranging wheel 14 respectively, and the oiling wheel 8 can move left and right following the wire rope.

[0025] Furthermore, a sealing cap 16 is threadedly connected to the upper end of the oil box 9, and an adjusting head 17 is installed on the oil filling pipe 10. By rotating the sealing cap 16, it is convenient to add oil to the inside of the oil box 9. The setting of the adjusting head 17 facilitates the control of the oil discharge volume of the oil filling pipe 10 to avoid excessive oil discharge and waste of oil. During daily use, the oiling wheel 8 is in contact with the wire rope and is driven to rotate by the wire rope.

[0026] The method of use of this embodiment is as follows: by controlling the drive motor 5 to rotate and drive the reel 2 to reel and unreel the wire rope, the elevator crane car is lifted and lowered. During this process, the wire rope contacts the oiling wheel 8 and the wire arrangement wheel 14. When the wire rope needs to be oiled and maintained, the oil inside the oil box 9 flows to the oiling wheel 8 through the oil filling pipe 10 by rotating the adjusting head 17. As the oiling wheel 8 rotates, the wire rope can be oiled. When the elevator crane car stops at a certain floor, the drive motor 5 stops rotating to stop the elevator crane car. At the same time, the electric push rod 602 extends to drive the movable plate 603 to move. The movable plate 603 drives the locking groove 11 on the locking plate 604 to contact the locking gear 605, so that the locking gear 605 can be locked. When the elevator crane car needs to rise and fall, the locking plate 604 is controlled to move up and not contact the locking gear 605.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
