Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

As shown in figures 1 and 2, the C-shaped steel track pulley for the cable comprises a C-shaped steel 1 with an opening end facing to the lower side, a connecting piece 2 penetrates through the opening end of the C-shaped steel 1, a plurality of idler wheels 3 arranged in parallel with the side wall of the C-shaped steel 1 are mounted on the side face of the connecting piece 2, and a clamping mechanism used for limiting the cable is connected onto the connecting piece 2.

The utility model discloses in adopt C shaped steel as the track, can make processing site department float and sink etc. be difficult to enter into C shaped steel 1's downside inner wall on, after impurity such as float and sink on C shaped steel 1's downside inner wall reduces, along the steady operation that gyro wheel 3 that it removed can be more, consequently the utility model discloses adaptability to the environment is strong, moves moreover more steadily.

The utility model discloses in especially important, the current gyro wheel of comparison slides along V type track design, the utility model provides a when gyro wheel 3 places on C shaped steel 1's downside inner wall, the direction of gravity of connecting piece 2, fixture and cable that gyro wheel 3 bore is tangent with gyro wheel 3's roll direction, consequently makes bearing radial load that bears that the bearing in the gyro wheel 3 can be better, and the slant shearing force that receives such as the ball in the messenger's bearing and steel ring is less, has prolonged gyro wheel 3's life, has also guaranteed the rolling smoothness nature of gyro wheel 3.

The utility model discloses in, when the direction of gravity that gyro wheel 3 received is tangent with the direction of rolling, gyro wheel 3 can not produce the sideslip removal of skew direction of rolling for C shaped steel 1, consequently gyro wheel 3 has less frictional force when rolling along C shaped steel 1 to make gyro wheel 3 be difficult to more when rolling and produce the spark, further guaranteed service environment's safety, consequently this use novel also can be extensive be applied to on the hoisting equipment of warehouse, shipyard, pier, explosion-proof workshop etc..

In order to make gyro wheel 3 roll to C shaped steel 1 end department back, can not produce the damage to the cable because of sudden impact, further, the end connection of connecting piece 2 orientation along the direction that C shaped steel 1 moved has damping piece, and damping piece can cushion the striking process after gyro wheel 3 rolls to C shaped steel 1 end department, makes the cable can not follow fixture swing by a wide margin, plays the purpose of protection to the cable.

Optionally, the damping piece is a soft rubber sleeve 4 fixedly coated on the connecting piece 2, or the damping piece is a spring fixedly connected to the connecting piece 2.

In order to make the roller 3 roll more smoothly in the C-section steel 1, it is preferable that the left, right and upper portions of the roller 3 have a gap with the inner wall of the C-section steel 1 after the lower portion of the roller 3 contacts the inner wall of the C-section steel 1, and since the left, right and upper portions of the roller 3 have a gap with the inner wall of the C-section steel 1, when the roller 3 rolls in the C-section steel 1, the roller 3 does not contact other inner wall surfaces but the roller 3 contacts the inner wall of the C-section steel 1, and thus the rolling is more smoothly.

Specifically, the clamping mechanism comprises a frame 5 penetrating through the connecting piece 2, an external thread is arranged on a vertical section 51 of the frame 5, a fixing piece 6 is fixedly connected to the vertical section 51, a soft rubber layer 7 is connected to the lower surface of the fixing piece 6, a groove 71 for allowing a cable to penetrate through is arranged on the lower surface of the soft rubber layer 7, a cable supporting piece 8 which is movably penetrated through by the vertical section 51 and is in a convex shape is arranged on the lower portion of the soft rubber layer 7, and a nut 9 is screwed on the vertical section 51 positioned on the lower portion of the cable supporting piece 8; when the cable needs to be limited so that the cable can move along with the pulley, the cable firstly passes through the groove 71, then the nut 9 is rotated, the cable supporting piece 8 moves, and therefore the purpose of limiting the cable is achieved through the matching effect of the cable supporting piece 8 and the groove 71.

In order to enable the pulleys composed of the connecting pieces 2, the rollers 3 and the like which are arranged in the C-shaped steel 1 to move synchronously, furthermore, a plurality of traction holes 21 for the traction ropes to pass through are formed in the connecting pieces 2, and after one pulley moves, the other pulleys can synchronously move in the same direction by passing the traction ropes through the traction holes 21.
