Description

Technical Field

[0001] The utility model relates to the technical field of take-up wheels, in particular to a take-up wheel capable of preventing misoperation and a vehicle-mounted lifting rod comprising the same. Background Art

[0002] The main function of the take-up wheel is to wind the cable on the take-up wheel body. A spiral spring is provided inside the take-up wheel body. When the cable is pulled, the cable drives the take-up wheel body to rotate and release the cable. The spiral spring stores energy and the cable is released from the take-up wheel body. When the cable is released, the spiral spring rotates to recycle the excess cable.

[0003] The take-up wheel is used in many traditional industries. For example, it is used in the lift industry to reel in and out the cables of the equipment on the top of the vehicle lift. Due to the uneven mass distribution on the take-up wheel and the elastic element of the scroll spring driven inside it, during driving (when the lift is in the closed state), especially when the vehicle accelerates or decelerates, the take-up wheel will generate a rotational torque, and the take-up wheel will repeatedly rotate back and forth. This is an undesirable state and may cause damage to the cable. Utility Model Content

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-3 As shown, an embodiment of the utility model proposes a take-up reel that prevents misoperation, including: a take-up reel body 1 and a mounting frame 8, the take-up reel body 1 is rotatably mounted on the fixing frame 2, a stop disc 3 is fixedly provided on the side wall of the take-up reel body 1, and a plurality of stop holes 4 are evenly arranged on the stop disc 3 around its surface, and a stop assembly 5 is also provided on one side of the take-up reel body 1, and the stop assembly 5 is used to cooperate with the stop hole 4 to limit the rotation of the take-up reel body 1.

[0024] By fixing the anti-rotation disk 3 on the side wall of the take-up reel body 1 and setting it coaxially with the take-up reel body 1, and setting a anti-rotation hole 4 on the cross section of the anti-rotation disk 3, when the take-up reel body 1 needs to be in a stationary state, it is only necessary to control the anti-rotation component 5 to be inserted into the anti-rotation hole 4. The anti-rotation component 5 cooperates with the anti-rotation disk 3 to limit the rotation of the take-up reel body 1, thereby limiting the take-up reel body 1 from retracting and releasing the cable 6, ensuring that the take-up reel body 1 will not rotate back and forth significantly during transportation.

[0025] like Figure 4 as well as Figure 5 As shown, the anti-rotation assembly 5 includes: a mounting frame 8, a mounting cylinder 9, a anti-rotation pin 7 and a pulling mechanism. The mounting cylinder 9 is horizontally arranged on the mounting frame 8. The mounting cylinder 9 passes through the mounting frame 8. A mounting cavity is provided in the mounting cylinder 9. An elastic mechanism is provided in the mounting cavity. The elastic mechanism extends out of the mounting cylinder 9 at one end close to the anti-rotation disk 3. The anti-rotation pin 7 is fixed to the end of the elastic mechanism extending out of the mounting cylinder 9, and the pulling mechanism is connected to the other end of the elastic mechanism.

[0026] like Figure 6 as well as Figure 7As shown, the elastic mechanism includes: an elastic member, a base 10, an intermediate rod 11, and a connecting rod 12. The base 10 is slidably disposed in the mounting cavity. The ends of the intermediate rod 11 are respectively connected to the pulling mechanism and the connecting rod 12. The elastic member is disposed between the side of the mounting cavity and the base 10. The base 10 is fixedly connected to the connecting rod 12. The connecting rod 12 extends out of the mounting tube 9 and is slidably connected thereto. The anti-rotation pin 7 is fixed to the end of the connecting rod 12 extending out of the mounting tube 9. Preferably, the elastic member is a spring 13.

[0027] like Figure 5 as well as Figure 7 As shown, the pulling mechanism includes: a handle 14 and a mounting column 15, the handle 14 is fixed to one end of the mounting column 15, and a rectangular block 16 is provided at the other end of the mounting column 15, the rectangular block 16 is slidably connected to the mounting tube 9, and the rectangular block 16 is connected to the middle rod 11.

[0028] Specifically, when the take-up reel body 1 is in a stationary state, under the elastic force of the spring 13, the spring 13 pushes the base 10 to move in the installation cavity toward the stop hole 4, and the base 10 drives the connecting rod 12 fixedly connected to it to move, so that the stop pin 7 at the end of the connecting rod 12 is inserted into the stop hole 4. Under the restriction of the stop pin 7, the stop disk 3 is fixed, thereby restricting the rotation of the take-up reel body 1; when the stop disk 3 needs to be released, it is only necessary to pull the handle 14 to disengage the stop pin 7 from the stop hole 4.

[0029] Furthermore, it also includes: a mounting plate 17, the mounting plate 17 is fixed to the end of the mounting tube 9 away from the anti-rotation pin 7, and the mounting plate 17 is provided with a rectangular hole for the rectangular block 16 to pass through. After the rectangular block 16 on the anti-rotation pin 7 has completely passed through the rectangular hole on the mounting plate 17, the handle 14 is rotated at a certain angle. At this time, the rectangular block 16 of the anti-rotation pin 7 is axially limited by the mounting plate 17 under the action of the thrust of the spring 13, thereby completing the retraction and axial fixation of the anti-rotation pin 7. At this time, the anti-rotation end of the anti-rotation pin 7 is away from the outer end surface of the anti-rotation disk 3, and the take-up reel body 1 rotates normally.

[0030] More specifically, the reason why the take-up reel body 1 rotates while the vehicle is in motion is that its mass distribution is uneven, and when the vehicle is accelerating or decelerating, a torque is generated, causing rotation. This torque is small, and an approximate torque can be obtained through multiple tests or experience. Usually, this torque is significantly smaller than the torque generated on the take-up reel body 1 by the maximum force that the cable 6 can withstand. Taking into account the working elastic force of the spring 13, the angle of the bevel of the stop pin 7, and the distribution radius of the stop hole 4, the stop assembly is designed to ensure that the torque generated by the cable 6 driving the stop disk 3 on the take-up reel to rotate can drive the stop pin 7 to retract, while the torque generated by the vehicle cannot drive the stop pin 7 to retract.

[0031] For example: Through experiments and experience, it is found that the torque of a certain take-up reel body 1 during driving rotation does not exceed 2N·m. A cable can usually withstand a force of more than 50N. The distance between the outlet of the take-up reel body 1 and the axis of rotation is 0.2m, so the torque generated by the cable 6 driving the take-up reel body 1 can reach 10N·m. The take-up reel body 1 is designed to be able to drive the stop pin 7 to retract under a torque of 6N·m (between the driving torque and the torque that can be generated without damaging the cable). If the distribution radius of the stop hole 4 is 0.2m, the force to retract the stop pin 7 is 30N. If the angle between the inclined surface of the stop pin 7 and the axis is 45°, the axial thrust generated is 21.2N. The spring 13 is designed to ensure that the thrust of the end face of the stop pin 7 facing the inner hole end face is about 21.2N. When the tension on the cable 6 gradually exceeds 30N, the end face of the anti-rotation pin 7 can be pushed out to the outer end face of the anti-rotation disk 3. At this time, the cable 6 and the structural parts are not damaged. The take-up wheel body 1 rotates under the drive of the cable 6. When it reaches the next anti-rotation hole 4, the anti-rotation pin 7 bounces into the hole under the elastic force of the spring 13. The take-up wheel body 1 keeps rotating, and the anti-rotation pin 7 keeps repeating the pushing and rebounding actions, thereby continuously emitting a "dang, dang, dang" sound of the anti-rotation pin 7 hitting the anti-rotation disk 3, prompting the operator that the anti-rotation disk 3 has not been unlocked and there is an erroneous operation, so the lifting rod stops;

[0032] The maximum torque of 2N·m generated during driving generates an axial thrust of about 5.7N on the stop pin 7, which is less than the thrust of 21.2N on the end face of the inner hole of the stop pin 7 and is insufficient to push the stop pin 7 out of the stop hole 4. Therefore, the take-up wheel body 1 will not rotate during driving.

[0033] like Figure 4 As shown, in order to facilitate fixing the fixing frame 2 on the vehicle-mounted platform, a fixing plate 18 is further provided at the bottom of the mounting frame 8 , and fixing holes for bolts to pass through are provided on the fixing plate 18 .

[0034] The utility model also provides a vehicle-mounted lifting rod, comprising the aforementioned anti-misoperation take-up wheel and a lifting rod body.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
