Description

Technical Field

[0001] The utility model belongs to the technical field of gate control of water conservancy projects, and in particular relates to a steel wire rope anti-slip groove device for a winch-type hoist. Background Art

[0002] The winch-type gate hoist controls the rapid gate with the advantages of large opening and closing stroke, small space occupied during opening and closing stroke, low cost, and convenient installation. It is widely used in water conservancy projects. The winch-type gate hoist mainly includes a drum, a reduction box, a motor, a brake, a wire rope and a movable pulley. One end of the wire rope is wound on the drum, and the other end is connected to the movable pulley, which is connected to the gate. When working, the motor drives the drum to rotate and reel or unreel the wire rope, thereby realizing the lifting and lowering function of the pulley and the gate. In order to make the wire rope wound on the drum in an orderly manner, a row of spiral grooves matching the size of the wire rope is provided on the drum. When the drum rolls up the wire rope, the wire rope is arranged horizontally in the groove. In actual use, the drum rope hoist controls the gate to rise rapidly, and sometimes the wire rope will be out of the groove and tangled or entangled. The wire rope is easily twisted and deformed due to extrusion, which not only easily causes the wire rope to be scrapped, increases maintenance costs, but also poses equipment safety hazards.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1 As shown, a winch-type hoist wire rope anti-slip groove device includes a drum 1, a movable pulley 2, a support frame 3 arranged on the movable pulley, two guide components symmetrically distributed on both sides of the support frame and two wire ropes 4 symmetrically wound on the drum. One end of each wire rope is wound on the drum, and the other end passes through the corresponding guide component on one side and is connected to the movable pulley. The wire rope near one end of the movable pulley is limited by the guide component to control the angle between the wire rope and the drum. Figure 1By comparing the two states before and after the adjustment of the wire rope, it can be seen that the angle between the wire rope and the drum after adjustment is significantly larger than the angle before adjustment. According to this principle (achieved by adjusting the position of the guide assembly on the support frame), the winding direction of the wire rope can be matched with the spiral groove arrangement structure (existing technology, not shown in the figure), avoiding the wire rope from slipping out of the groove, thereby reducing maintenance costs and eliminating equipment safety hazards.

[0027] Combination Figures 2 to 4 As shown, the support frame includes an I-shaped frame body 301 and two adjustment frames 302 respectively connected to the two ends of the I-shaped frame body, the adjustment frame is provided with a through slot 5 for accommodating the guide assembly, the adjustment frame is a horizontally arranged U-shaped structure, and its open side is covered on the outside of the I-shaped frame body, the I-shaped frame body includes an upper beam, a column and a lower beam connected in sequence, and the two adjustment frames are covered on the outside of the two ends of the upper beam, and the upper beam is provided with at least two evenly spaced positioning holes 3011, each adjustment frame is provided with a matching hole 3021, the matching hole is assembled and connected with one of the positioning holes through a first bolt 6, and the positioning hole and the matching hole can be freely selected according to actual needs. The structural design is convenient for controlling the position of the adjustment frame at the end of the upper beam, that is, controlling the overall width of the support frame, so as to meet the requirements of different winding angles of the wire rope. In this embodiment, the number of matching holes on each adjustment frame is two, which is convenient for improving the strength and stability of the connection structure. In addition, the I-shaped frame body is provided with at least two uniform adjustment frames, and the two side walls are provided with strip holes 3022 arranged along the length direction thereof. The guide wheel is assembled and connected with the strip hole on the adjustment frame through the second bolt 8. The second bolt passes through the guide wheel, and the position of the second bolt in the strip hole can be finely adjusted according to actual needs, thereby fine-tuning the position of the guide assembly to improve the accuracy of the winding angle between the wire rope and the drum. Each guide assembly includes two guide wheels 7 that cooperate with each other, and each wire rope passes through the middle of the two guide wheels of the guide assembly on the corresponding side. The outer peripheral surface of the guide wheel is a structure with a concave middle portion, and the size of the concave portion 701 thereof matches the size of the wire rope to ensure the stability of the wire rope.

[0028] The utility model works as follows:

[0029] like Figures 1 to 4 As shown, before use, first, according to the arrangement of the spiral grooves on the drum 1, the matching positioning holes 3011 are adaptively selected and connected with the matching holes 3021 on the two adjustment frames 302 through the first bolt 6, and then the position of the second bolt 8 in the strip hole 3022 is adjusted to achieve precise adjustment of the position of the guide assembly, and at the same time, according to the size of the wire rope, the matching guide wheel 7 is selected and installed. During use, according to the winding condition of the wire rope on the drum 1, the position of the guide assembly can be changed by controlling the second bolt 8 again to achieve fine adjustment, so as to ensure that the winding direction of the wire rope matches the spiral groove arrangement structure.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
