Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a winch for pulling in tunnel construction. Background Art

[0002] After searching, the Chinese patent publication number is CN219751749U, and the publication date is 2023-09-26. It discloses a winch for tunnel engineering, including a supporting chassis, a connecting box is arranged on the top surface of the supporting chassis, a winding device and a drum are fixedly connected to the same side of the connecting box, a fixing block is connected to the end of the drum away from the connecting box, a twisted rope is sleeved on the outer periphery of the drum, and fixing rods are symmetrically arranged on the inner wall of the supporting chassis, and a fixing device is arranged between the fixing rods. The utility model winch is convenient for users to operate and move. During the pulling process, the main body is fixed to fix the twisted rope, so that the twisted rope will not be knotted when being pulled, and the twisted rope is kept stable during the pulling process to reduce the shaking of heavy objects. However, when the device is in use, since the winding roller on the winch has a certain length, when the rope is wound onto the winding roller, the rope will move along the surface of the winding roller, and the part of the rope located above the fixing device will switch between a vertical state and an inclined state, and is in an inclined state most of the time. When winding, a large friction force will be caused between the cushion and the rope. Over time, the cushion will be subjected to the force and wear, affecting the normal use of the fixing device.

[0027] Embodiment 2

[0028] Based on Example 1, see Figure 3 Shown

[0029] The bottom of the L-shaped fixing frame 36 is provided with a mounting groove 5, in which a roller 6 is rotatably connected. The roller 6 fits in the groove 34. By providing the roller 6, the friction force of the L-shaped fixing frame 36 during movement can be reduced.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] The working principle of the utility model is as follows: the winch is moved to the place where towing is required, and the rope is passed through between the two groups of second pulleys 332 to be bound to the weight. During the winding process, the rope will move on the winding, and the two groups of second pulleys 332 are used to limit the rope, so that the rope below the positioning seat 31 is always kept in a vertical state, thereby ensuring that the weight below will not shake, and the rope located upwind of the positioning seat 31 will switch between a vertical state and an inclined state. When the rope is in the state, the force of the rope is applied to the first pulley 37, so that the L-shaped fixing frame 36 is forced to move to one side, and pressurizes the spring 352, so that the spring 352 is used to buffer the L-shaped fixing frame 36, thereby reducing the impact of the rope on the second pulley 332 when it is tilted.
