Detailed Description
The embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings, and the embodiments described below by referring to the drawings are exemplary and intended to explain the present invention so that the technical solutions of the present invention can be more easily understood and grasped, and cannot be construed as limiting the present invention.
Example 1:
a rope tensioning mechanism of a rope climbing machine is shown in figures 1, 2 and 3 and comprises a side plate 1, a rope winding disc 2 rotatably connected to the side plate 1, and a tensioning adjusting assembly 3 positioned on one side of the rope winding disc 2. Tension adjustment assembly 3 includes a fixed plate 31, an adjustment rod 32, a spring 33, an adjustment nut 34, a lever arm 35, and a pinch roller assembly 36. The improvement consists in tensioning the adjusting assembly 3 while simplifying the rope drum 2.
The fixed plate 31 is fixedly connected to the side plate 1 and supports one end of the spring 33, the spring 33 is sleeved on the adjusting rod 32, the other end of the adjusting rod 32 limits the other end of the spring 33 through an adjusting nut 34, the end of the adjusting rod 32 is rotatably connected to the end of the lever arm 35, the other end of the lever arm 35 is rotatably connected to the side plate 1, and the pressing wheel assembly 36 is rotatably connected to the middle of the lever arm 35 and faces the rope coiling disc 2.
The lever arm 35 includes an upper arm plate 351 and a lower arm plate 352, and the puck assembly 36 is sandwiched between and rotationally coupled to the upper arm plate 351 and the lower arm plate 352.
The adjustment is provided with a thread structure for adapting the adjusting nut 34, and the adjusting nut 34 is provided with a plurality of initial compression lengths of the series limiting springs 33.
In the course of the work, stay cord 4 twines serving as a contrast 2 a week, still slips easily through the contact surface of serving as a contrast 2 and stay cord 4, needs to lock stay cord 4. Through the effect of lever arm 35 for pinch roller subassembly 36 pushes down a position of rope, when serving as the serving as a contrast 2 and rotate and drive stay cord 4, pinch roller subassembly 36 is pressing stay cord 4 always, and pinch roller body 361 also follows the roll simultaneously, because pinch roller body 361 has curved surface recess 363, so more even to the application of force on stay cord 4 surface, make stay cord 4 also more durable, be difficult for causing the too big or uneven atress of stay cord 4 local atress. In addition, the two pressing wheel bodies 361 are adopted to press the pull rope 4, so that the stability of the structure is improved, the movement direction of the pull rope 4 is kept stable, and the pull rope 4 is not easy to separate. The pressure on the pull cord 4 for the puck assembly 36 is primarily provided by the springs 33. Since the ropes 4 are different in thickness, the pressing force needs to be adjusted. When the pull rope 4 is thinner, the adjusting nut 34 can be properly controlled to be adjusted outwards, so that the initial deformation of the spring 33 is less, the initial potential energy is less, the force for pressing the pull rope 4 is also less, when the pressure needs to be increased, the adjusting nut 34 can be controlled to be adjusted inwards, the elastic potential energy is increased, and the pressure is also increased. Can be adjusted according to the diameters and the stress of different pull ropes 4. A plurality of adjusting nuts 34 are arranged, so that the anti-loosening effect is achieved, and the working reliability is improved.
With reference to fig. 2 and 4, the rope winding disc 2 is provided with a rope groove 21 for winding the rope 4 in a half-wrapping manner, an arc-shaped convex hull 22 is arranged in the rope groove 21, and the convex hulls 22 are uniformly distributed on the rope groove 21. This can improve the gripping force of the rope reel 2 to the pulling rope 4.
Example 2:
with reference to the attached drawing of embodiment 1 and fig. 5, the other side surface of the fixing plate 31 supported by the spring 33 supports the unlocking lever 7, the unlocking lever 7 is sleeved on the adjusting rod 32, and the other end of the unlocking lever 7 is connected with the traction rope 5. The pulling rope 5 is provided with a pulling ring 6 for manual operation. Referring to fig. 5, the shape of the unlocking lever 7 is "7" shaped, the end of the unlocking lever 7 is empty and can be sleeved on the adjusting rod 32, the end is supported behind the fixing plate 31, the fixing plate 31 serves as a fulcrum of the unlocking lever 7, when the unlocking lever is used, the traction rope 5 is pulled, the unlocking lever 7 lifts the adjusting rod 32, when the adjusting rod 32 is lifted, the lever arm 35 is rotated outwards, the pinch roller assembly 36 is far away from the rope winding wheel, the design is such that the locking or fastening of the pinch roller assembly 36 to the pull rope 4 can be released in a manual mode under the condition that the motor is stopped or the battery is dead, the operation is convenient and fast, and labor is saved. Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
