DETAILED DESCRIPTION
[0026] The core of the present application is to disclose a rope tensioning device, which solves the problem of low efficiency caused by manual adjustment of the existing rope tensioning device.
[0027] As Figure 1The utility model discloses a kind of rope tensioning devices, including rope 10, fixed base 20, guide wheel assembly 30 and tensioning assembly 40, guide wheel assembly 30 at least includes one guide wheel 31, each guide wheel 31 is connected with fixed base 20, tensioning assembly 40 includes tensioning wheel 41, tensioning wheel support 42 and elastic adjusting mechanism 43, tensioning wheel 41 is connected with tensioning wheel support 42, elastic adjusting mechanism 43 includes elastic return piece 432, elastic return piece 432 is set between tensioning wheel support 42 and fixed base 20, the first end of elastic return piece 432 is connected with or abuts with tensioning wheel support 42, second end is connected or abuts with fixed base 20.Rope 10 passes through guide wheel 31 and tensioning wheel 41, and is connected with equipment. Preferably, the two ends of elastic return piece 432 are connected with tensioning wheel support 42 and fixed base 20 respectively, or abut with tensioning wheel support 42 and fixed base 20 respectively.
[0028] In use, when the load of the load end of rope 10 increases, the tension of rope 10 increases, elastic return piece 432 is compressed, and rope 10 is tightened through elastic reaction force, to maintain the tension of rope 10; when the load of the load end of rope 10 decreases, elastic return piece 432 is elongated, to release the stored elastic potential energy, and prevent rope 10 from being too tight. It should be noted that the equipment can be connected to any end of rope 10. Here, the equipment refers to a device to which rope 10 needs to be connected, such as an elevator, a part that needs to be hoisted or fixed, etc.
[0029] The rope tensioning device disclosed in the utility model embodiment can maintain the tensioned state of rope 10 when the load of the load end increases or decreases, can realize automatic adjustment without manual intervention, has high adjustment efficiency, and can reduce labor intensity; elastic adjusting mechanism 43 can dynamically adjust the tightness of rope 10, to ensure that it maintains uniform tension during operation, can avoid slackening or over-tightening due to changes in the load of the load end of rope 10, reduce the occurrence of safety hazards due to slackening, and can prolong the service life of rope 10.
[0030] It should be noted that the order in which rope 10 passes through guide wheel 31 and tensioning wheel 41 is not limited. Rope 10 can be guided by guide wheel 31 first and then pass through tensioning wheel 41, or pass through tensioning wheel 41 first and then be guided by guide wheel 31. The number of tensioning assembly 40 can include multiple, and the number of guide wheel 31 can include multiple.
[0031] Further, in some specific embodiments, as Figure 1 and Figure 2As shown, the guide wheels 31 include two, the first guide wheel 31 guides the rope 10 to the tensioning wheel 41, so that the rope 10 can pass through the tensioning wheel 41, and then be guided by the second guide wheel 31 to the connecting device, and the second guide wheel 31 can play an auxiliary tensioning role. Further, in order to ensure that the direction of the rope 10 is substantially unchanged, the two guide wheels 31 are arranged symmetrically with respect to the axis direction of the elastic return member 432. The first guide wheel 31 guides the rope 10 to the tensioning wheel 41, and the second guide wheel 31 provides a guiding action on the tensioned rope 10. It should be noted that the number of guide wheels 31 can include more, and the specific number and setting position can be set according to actual needs.
[0032] Further, in order to guide the compression of the elastic return member 432 and reduce the radial deformation caused by bending and deflection of the elastic return member 432 when compressed, the elastic adjusting mechanism 43 includes a spring shaft 431, the elastic return member 432 is sleeved on the outside of the spring shaft 431, one end of the spring shaft 431 is connected with the tensioning wheel support 42, and the connection can be achieved by welding, clamping or threaded connection, and the other end of the spring shaft 431 is in sliding fit with the fixed base 20.
[0033] Further, the spring shaft 431 is in sliding fit with the fixed base 20 through the first bearing 44, and the first bearing 44 is preferably an elliptical flange linear bearing, and the first bearing 44 is connected with the fixed base 20 by flange connection. The second end of the elastic return member 432 is connected with or abuts against the first bearing 44. When the first end of the elastic return member 432 is connected with the tensioning wheel support 42, the second end is connected with the first bearing 44; when the first end of the elastic return member 432 abuts against the tensioning wheel support 42, the second end abuts against the first bearing 44. The setting of the first bearing 44 can reduce the friction between the spring shaft 431 and the fixed base 20, and reduce wear.
[0034] Further, in order to prevent the elastic return member 432 from being excessively compressed when the load of the load end of the rope 10 is too large, the rope tensioning device further includes a fixed baffle (not shown in the drawings), which is arranged on the side of the fixed base 20 away from the tensioning wheel 41. When the elastic return member 432 is compressed to a preset compression amount, the spring shaft 431 abuts against the fixed baffle. This scheme can prevent the elastic return member 432 from being excessively deformed due to the load of the load end of the rope 10 being too large, and reduce the probability of damage to the elastic return member 432.
[0035] As Figure 2 and Figure 4As shown, in order to be able to absorb the vibration energy in the action of the elastic return piece 432, reduce the tension fluctuation, ensure the adjustment stability, a shock pad 45 is arranged at the bottom of the spring shaft 431, the shock pad 45 is provided with a connecting piece, the shock pad 45 is insertedly connected or threadedly connected with the spring shaft 431, and the shock pad 45 is preferably a rubber shock pad. When the load at the load end of the rope 10 increases, the elastic return piece 432 is stressed and compressed, the spring shaft 431 is slidingly matched with the fixed base 20 along the axis direction, the shock pad 45 is in contact with the fixed baffle, and the elastic return piece 432 is kept in a proper tension state.
[0036] Further, as shown in Figure 1 and Figure 3 , in order to prevent the rope 10 from loosening from the tensioning wheel 41, the tensioning wheel support 42 is provided with a limiting piece 421 capable of limiting the rope 10. Specifically, the tensioning wheel support 42 is in a whole U-shaped structure, including a second bottom plate 423 and support plates 422 located on both sides of the second bottom plate, and the tensioning wheel 41 is rotatably arranged between the two support plates 422. The limiting piece 421 can be a pin connected between the two support plates 422, or a limiting baffle, which is hingedly connected or fixedly connected with any one of the support plates 422. When the limiting baffle is fixedly connected with the support plate 422, the limiting baffle is preferably an L-shaped baffle, so that the rope 10 can be wound around the tensioning wheel 41. The tensioning wheel support 42 can be a one-piece structure or a split structure, and a one-piece structure is preferred to ensure structural stability.
[0037] Further, as shown in Figure 3 and Figure 5 , the guide wheel 31 is connected with the fixed base 20 through the guide wheel support 32, the guide wheel support 32 is connected with the fixed base 20, the guide wheel support 32 includes a first bottom plate 321 and wing plates 322 arranged on both sides of the first bottom plate 321, the first bottom plate 321 is connected with the fixed base 20, and the connection can be achieved by bolts, or by welding or clamping. The guide wheel 31 is rotatably arranged between the two wing plates 322, which facilitates the connection of the guide wheel support 32 with the fixed base 20 and the connection of the guide wheel 31 with the guide wheel support 32. The guide wheel support 32 can be a one-piece structure or a split structure, and a one-piece structure is preferred to reduce assembly difficulty.
[0038] Further, in order to reduce the friction when the guide wheel 31 and the tensioning wheel 41 rotate, the guide wheel 31 is connected with the guide wheel support 32 through a rotating shaft, and the guide wheel 31 is connected with the rotating shaft through a second bearing; and / or, the tensioning wheel 41 is connected with the tensioning wheel support 42 through a rotating shaft, and the tensioning wheel 41 is connected with the rotating shaft through a third bearing. The specific type of the second bearing and the third bearing can be selected according to actual needs.
[0039] Further, in some specific embodiments, the guide wheel 31 and the tensioning wheel 41 are both provided with a rope groove, which can limit the rope 10 and reduce the wear of the rope 10.
[0040] Further, in order to improve the wear resistance and high temperature resistance of the guide wheel 31, the guide wheel 31 is provided with a wear-resistant coating, preferably a ceramic coating.
