Wherein, wind set 1 is used for twining taking in being used for measuring rope 2, and aforementioned measuring rope 2 adopts the steel wire to under balancing weight 3's effect, measurement convenient operation, it is not fragile, it is less with the rock-wall friction to measure rope 2, can hang great balancing weight 3, the response is filled the sand face sensitively, that is to say when balancing weight 3 after removing to the bottom, it is obvious to the change of weight to measure rope 2, the telling measuring staff balancing weight 3 that can be accurate has removed to the bottom. The problem of be difficult to transfer the measuring rope in the hole of packing is solved, under 3 dead weights of balancing weight effects, the hole of packing that the negative inclination of drilling is more than or equal to 10 all measurable quantities, and measurement height or degree of depth all increase by a wide margin, can satisfy the gob height measurement in the pit completely.

Furthermore, balancing weight 3 includes weight ball 31, be provided with the straight type passageway of crossing its centre of sphere in the weight ball 31, the both ends of straight type passageway are followed the surface of weight ball 31 link up, be provided with location iron wire 32 in the straight type passageway, the both ends of location iron wire 32 stretch out respectively the both ends of straight type passageway and two liang of fixes, location iron wire 32 encircles and forms the iron wire ring, the iron wire ring with measure the end fixing of rope 2.

This sample utility model discloses when carrying out the measurement of slope through-hole, weight and the rock-wall contact on the balancing weight 3 to weight ball 31 can roll down along the drilling lateral wall of slope under the effect of self gravity, and then pulls through location iron wire 32 and measure rope 2, thereby lets measure rope 2 and remove along the lateral wall of slope, stops after rolling to the bottom until weight ball 31.

Further, the winding device 1 comprises a winch 11, a winch 12 is rotatably mounted on the winch 11, and the measuring rope 2 is wound on the winch 12.

Preferably, as shown in fig. 2, fig. 3 and fig. 4, in order to finely adjust a winding end of the entire winding device 1, that is, a portion for receiving the measuring cord 2, so as to enable the measuring cord 2 to move better, the winding device 11 includes a first frame body 111 and a second frame body 112, the bottom ends of the first frame body 111 and the second frame body 112 are connected through a connecting rod 113, horizontal mounting plates 114 are disposed on the first frame body 111 and the second frame body 112, a sliding groove 115 extending horizontally is disposed on the mounting plates 114, a moving rod 116 is rotatably mounted at a rotating shaft end of the winch 12, the moving rod 116 is slidably mounted in the sliding groove 115, and a fastening device 117 is disposed between the rotating rod and the sliding groove 115.

In this way, the position of the winch 12 can be finely adjusted by the sliding of the moving rod 116 in the sliding groove 115, and the paying-off work can be further performed.

Furthermore, the first frame 111 and the second frame 112 are further connected by a damping rotating shaft 4 parallel to the connecting rod 113, ends of the two mounting plates 114 are fixed to a shaft body of the damping rotating shaft 4, supporting blocks 5 are mounted on opposite sides of the first frame 111 and the second frame 112 to the damping rotating shaft 4, and the supporting blocks 5 are disposed on a rotating path of the mounting plates 114 along the damping rotating shaft 4.

Thus, by using the movable damping rotating shaft 4, the whole mounting plate 114 and the winch 12 arranged on the mounting plate 114 can be moved, that is, the mounting plate 114 and the winch 12 can be rotated around the damping rotating shaft 4, so that when a vertical channel needs to be measured, the winch 12 can be rotated out from between the first frame body 111 and the second frame body 112 by rotating the winch 12, and further the whole winch 12 is arranged outside the first frame body 111 and the second frame body 112, so that the measuring rope 2 unwound from the winch 12 can vertically droop under the action of self gravity, and in the process of vertical droop, the measuring rope cannot be influenced by the first frame body 111 and the second frame body 112.

Specifically, please refer to fig. 5, the damping rotating shaft 4 includes a main shaft 41 disposed between the first frame 111 and the second frame 112, both ends of the main shaft 41 are coaxially connected with a damping shaft 42, the damping shaft 42 passes through the first frame 111 or the second frame 112, a position-limiting ring 43 is coaxially mounted on a portion of the damping shaft 42 located between the first frame 111 and the second frame 112, the position-limiting ring 43 is in sliding contact with a side wall of the first frame 111 or the second frame 112, a section of the damping shaft 42 extending out of the first frame 111 or the second frame 112 is provided with an external thread and is threadedly mounted with 44, and a plurality of rubber gaskets are coaxially sleeved on the damping shaft 42 between 44 and the first frame 111 or the second frame 112.

Like this when needing to utilize damping pivot 4 to fix a position, wrench movement 44 lets 44 extrude the rubber gasket, and then utilizes rubber gasket and spacing ring 43 to the extrusion of first support body 111 or second support body 112, increases the frictional force of damping axle 42 between pivoted in-process and first support body 111 or second support body 112 to realize the increase damping, let damping axle 42 also be main shaft 41 and fix a position the purpose. When the winch needs to be stored, the damping shaft 44 is rotated to be loosened, so that the rotating friction force between the damping shaft 42 and the first frame body 111 or the second frame body 112 is reduced, an operator can conveniently move the winch 12, and the mounting plate 114 can be freely placed on the supporting block 5 when the winch needs to be stored.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
