Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-3, a rope saw with tensioning structure, including equipment main part 1 and by the saw rope 2 that equipment main part 1 outwards stretches out, the outside of equipment main part 1 is provided with tensioning case 3, the inside of tensioning case 3 is provided with control box 4 and leading truck 5, control box 4 internal rotation is connected with two swing arms 8, swing arms 8 outwards stretch out from the bottom both sides of control box 4 respectively, swing arms 8 are provided with first take-up pulley 10 in the position that is close to respective lower extreme respectively, the lower extreme of two swing arms 8 is connected with linking arm 9 in the rotation respectively, sliding connection has sliding seat 7 in the sliding seat 5 in the lower extreme of two linking arms 9 respectively, install second take-up pulley 11 on the sliding seat 7 rotation, saw rope 2 that conveys on the equipment main part 1 is passed through in proper order two first take-up pulleys 10 of top and second take-up pulley 11 below again in the equipment main part 1.

The front side inner wall of the control box 4 is rotatably mounted with two bushings 14 through bearing sleeves, and the rear side inner wall of the control box 4 is rotatably mounted with two gears 6 in meshing relationship through bearing sleeves. A transmission shaft 12 is inserted between the side-by-side shaft sleeves 14 and the gear 6 in a sliding manner. The shaft of the drive shaft 12 is provided with a first spline 15 rotating coaxially with the sleeve 14 and with a second spline 16 rotating coaxially with the gear 6.

It is also necessary to supplement that the outside of the control box 4 is provided with a motor 13 driving the drive shaft 12.

In order to ensure a comparatively coordinated adjustment of the tensioning device, the pendulum arms 8 and the connecting arms 9 arranged on both sides are therefore distributed symmetrically with respect to the central axis of the control box 4, and the guide frame 5 is arranged directly below the control box 4.

In this embodiment 1, the saw wire 2 as a whole is tensioned: the transmission shaft 12 is controlled to slide along the axial direction, so that the first spline 15 and the second spline 16 are respectively inserted into the shaft sleeve 14 and the gear 6 in a sliding manner, when the transmission shaft 12 rotates, the gear 6 is in a meshed relation state, and the shaft sleeves 14 on two sides keep synchronous opposite rotation states, so that the swing arms 8 on two sides simultaneously rotate towards the middle, the connecting arm 9 pushes the sliding seat 7 downwards along the guide frame 5, the distance between the first tensioning wheel 10 positioned above and the second tensioning wheel 11 positioned below is enlarged, and the purpose of tensioning the saw ropes 2 is achieved. Only one motor 13 is provided at this time.

In this example 2, the saw wire 2 was tensioned at different slack portions: the drive shaft 12 is controlled to slide axially such that the first spline 15 is slidably inserted into the sleeve 14 and the second spline 16 is not yet slidably inserted into the gear 6, so that when the drive shaft 12 rotates, the gear 6 does not rotate and the sleeve 14 and the swing arm 8 can synchronously rotate.

When the saw rope 2 on the left side is loosened, the swing arm 8 on the right side is controlled to turn outwards, so that the loosened part on the left side is tensioned; when the saw rope 2 on the right side is loosened, the swing arm 8 on the left side is controlled to turn outwards, so that the loosened part on the right side is tensioned. During the turning of the individual swing arms 8, the slide seat 7 will slide up and down synchronously along the guide frame 5 by the transmission of the connecting arm 9, whereby two motors 13 are required in order to ensure that the swing arms 8 on the left and right can be operated relatively independently.

Finally, it should be specifically mentioned that, regarding the design positions of the first spline 15 and the second spline 16, since the positions of the sleeve 14 and the gear 6 are determined first, the spacing between the first spline 15 and the second spline 16 can be calculated and determined according to the positions of the sleeve 14 and the gear 6, and in embodiment 1, the spacing between the first spline 15 and the second spline 16 can be the same as the spacing between the sleeve 14 and the gear 6; whereas in embodiment 2 the spacing between the first spline 15 and the second spline 16 may be increased appropriately to ensure that the second spline 16 has not yet slid into the gear 6 when the first spline 15 is slid from right to left and inserted into the sleeve 14.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
