DETAILED DESCRIPTION
[0023] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0024] In the present disclosure, the orientation words such as "inner, outer" used herein refer to the inner and outer relative to the contour of the structure or component itself; "first, second" and the like are used to distinguish one element from another element, and do not have sequentiality and importance; in addition, the same reference signs in different reference drawings represent the same elements.
[0025] In a first aspect of the present disclosure, a drum limiting device of a winding hoist is provided, referring to Figures 1 to 4 as shown, the drum 1 comprises a barrel 110 and a baffle 120 arranged on the barrel 110, and the drum limiting device comprises at least one limiting mechanism 2, wherein the limiting mechanism 2 comprises a base 210 and a locking assembly 220, one end of the locking assembly 220 is hinged to the base 210, and the other end is used for lockably connecting to the matching part 121 of the baffle 120, so as to limit the circumferential rotation of the drum 1.
[0026] Through the technical scheme, i.e., the drum limiting device of the winding type elevator provided by the present disclosure, when the material is transported through the drum limiting device, one end of the rope (for example, a steel wire rope) can be connected to the outer side wall of the cylinder 110, and the rope can be retracted or extended by rotating the drum 1 to hang the material on the rope for vertical transportation of the material. After the material is transported to the specified height, the locking assembly 220 of the limiting mechanism 2 can be connected to the matching part 121 on the baffle 120 to limit the circumferential direction of the drum 1, so as to prevent the drum 1 from rotating in the circumferential direction. At this time, the rope connected to the outer side wall of the cylinder 110 can also remain in a stationary state, which is convenient for workers to load and unload the material at the specified height.
[0027] In addition, in the above-mentioned embodiments, the limiting mechanism 2 is not limited to limiting the circumferential rotation of the drum 1 only when the material is transported by the rope. When the rope of the drum 1 of the winding type elevator is replaced or the drum 1 is periodically maintained, the locking assembly 220 of the limiting mechanism 2 can also be connected to the matching part 121 of the baffle 120 to limit the circumferential rotation of the drum 1.
[0028] In addition, the number of limiting mechanisms 2 can be multiple, for example, as shown in Figure 1 In the drum 1 of the prior art which is relatively mature, the baffles 120 are usually arranged at intervals in the axial direction of the drum 1. The rope can be located between the two baffles 120 to be limited by the two baffles 120, so as to prevent the rope from detaching from the cylinder 110 when the rope is wound on the outer side wall of the cylinder 110. In this arrangement, multiple limiting mechanisms 2 can be connected to multiple matching parts 121 on a single baffle 120, for example, as shown in Figure 1 In the embodiment shown in Figure 1 In the embodiment shown in Figure 1In the illustrated embodiment, each of the two baffles 120 is connected to two limiting mechanisms 2. In an embodiment not shown in the figure, one baffle 120 may be connected to two limiting mechanisms 2, and the other baffle 120 may be connected to three or other numbers of limiting mechanisms 2, etc. This disclosure does not make any specific limitation in this regard.
[0029] It should be noted that the locking component 220 can be rotatably connected relative to the base 210. When there are multiple mating parts 121, the locking component 220 can be connected to mating parts 121 at different positions on the baffle 120 of the roller 1 by rotating relative to the base 210, thereby improving the flexibility of the roller limiting device in locking the roller 1.
[0030] Furthermore, the locking component 220 and the mating part 121 can also be constructed as any suitable mating connection structure. For example, the locking component 220 can be a buckle that can lock or unlock the mating part 121, and the mating part 121 can be a buckle seat, a handle, or other suitable auxiliary fastener that engages with the buckle for locking. The specific structure of the locking component 220 and the mating part 121 will be described in detail below, and will not be elaborated further here.
[0031] In some implementations, reference Figures 1 to 4 As shown, the baffle 120 is an annular plate connected to the circumference of the cylinder 110; the mating part 121 includes a plurality of mounting holes spaced apart along the annular plate; the locking assembly 220 includes a locking member 221 that can be unlockably connected to the mounting holes. In this way, when the cylinder 110 rotates, the annular plate can also rotate with the cylinder 110, and the plurality of mounting holes spaced apart on the annular plate can also be locked with the mounting holes by the locking member 221 when the cylinder 110 rotates to any suitable position, thereby improving the flexibility of locking the roller 1 by the locking member 221 at any suitable position.
[0032] In some implementations, reference Figures 1 to 4 As shown, the locking member 221 includes a limiting rod 2211 and at least one connecting plate 2212. The connecting plate 2212 has a hole. The locking member 221 is fixed to the baffle 120 by the limiting rod 2211 passing through the hole and the mounting hole. In this way, when the locking member 221 is fixed to the baffle 120 by the mounting hole, the hole on the connecting plate 2212 and the mounting hole on the baffle 120 can be aligned to a coaxial position. Then, by passing the limiting rod 2211 through both the hole on the connecting plate 2212 and the mounting hole on the baffle 120, the baffle 120 can be locked to the locking member 221 to limit and fix the roller 1.
[0033] It should be noted that the number of connecting plates 2212 mentioned in the above embodiment is one, which is exemplary.Figure 2 In the embodiment shown, the number of connecting plates 2212 can also be two, that is, a fork arm-like structure formed by two connecting plates 2212 can clamp the opposite two side walls of the baffle 120, and the limiting rod 2211 can pass through the holes provided on the two connecting plates 2212 and the mounting holes on the baffle 120 at the same time to limit the baffle 120, so as to finally limit the roller 1, and the limiting rod 2211 can also be configured in the form of a screw rod. After the screw rod passes through the holes of the connecting plates 2212 and the mounting holes of the baffle 120, two nuts can be threadedly connected to the screw rod, and the end faces of the two nuts are respectively attached to the end faces of the connecting plates 2212 away from the baffle 120, so as to limit and fix the roller 1. Figure 2
[0034] In some embodiments, referring to Figures 1 to 4 The locking assembly 220 further includes a matching part 222 connected to the locking part 221, and the locking part 221 can move along the length direction of the matching part 222 to be adjustably connected to the matching part 222. In this way, when the locking part 221 needs to be connected to the mounting holes at different positions of the baffle 120, the locking part 221 can be moved along the length direction of the matching part 222 to be connected to the mounting holes at different positions of the baffle 120. For example, the roller limiting device is usually arranged at the bottom of the roller 1 of the winding type elevator, and the locking part 221 can be moved along the length direction of the matching part 222 to select the mounting holes at different positions of the baffle 120 of the roller 1 for connection and locking.
[0035] It should be noted that the matching part 222 mentioned in the above specific embodiments can be any suitable structure, for example, the matching part 222 can be a telescopic rod, one end of the telescopic rod can be connected to the locking part 221, and the telescopic rod can drive the locking part 221 to move along the length direction of the telescopic rod. Alternatively, the matching part 222 can be a sliding rail, and the locking part 221 can be provided with a sliding block matched with the sliding rail, and the sliding block can move along the extension direction of the sliding rail to achieve the movement of the locking part 221 along the length direction of the matching part 222. Alternatively, the matching part 222 can be other suitable rod structures, which will be described in detail below, and will not be described here.
[0036] In some embodiments, referring to Figures 1 to 4 As shown, the locking assembly 220 includes a first segment 220a, a second segment 220b and a third segment 220c, wherein the first segment 220a is hinged to the base 210; the second segment 220b is connected to the first segment 220a and can move relative to the length direction of the first segment 220a, the fitting part 222 is formed on the second segment 220b; the third segment 220c is connected to the second segment 220b and can move relative to the length direction of the second segment 220b, and the locking part 221 is arranged on the third segment 220c. In this way, the length of the drum limiting device can be adjusted more flexibly by the three segments connected in sequence, that is, the first segment 220a and the third segment 220c can move along the length direction of the second segment 220b to shorten or lengthen the length of the locking assembly 220 as a whole, and can be more flexibly connected to the mounting holes at different positions on the baffle 120. In addition, the first segment 220a is hinged to the base 210, so that the locking assembly 220 can also rotate relative to the base 210 and can be connected to the mounting holes at different positions on the baffle 120, thereby improving the flexibility of the drum limiting device. In Figure 4 In some embodiments, the second segment 220b can be a rod body with a certain length, and the rod body can form the fitting part 222. In this way, the first segment 220a and the third segment 220c can be provided with holes matched with the rod body, so that the first segment 220a and the third segment 220c can move along the length direction of the rod body through the cooperation of the holes and the shaft. In addition, the first segment 220a and the third segment 220c can also be connected to the mounting holes at different positions on the baffle 120 through the cooperation of the holes and the shaft. Figure 4 In the embodiment shown, the same structure is adopted, that is, the third segment 220c can include two connecting plates 2212 and a limiting rod 2211, and the two connecting plates 2212 and the limiting rod 2211 can be used to lock and fix the mounting holes on the baffle 120. In addition, the first segment 220a can also include two connecting plates 2212 and a limiting rod 2211, and the two connecting plates 2212 and the limiting rod 2211 can be hinged to the base 210 together, so that the first segment 220a can rotate relative to the base 210.
[0037] In some embodiments, the second segment 220b can be a rod body with a certain length, and the rod body can form the fitting part 222. In this way, the first segment 220a and the third segment 220c can be provided with holes matched with the rod body, so that the first segment 220a and the third segment 220c can move along the length direction of the rod body through the cooperation of the holes and the shaft. In addition, the first segment 220a and the third segment 220c can also be connected to the mounting holes at different positions on the baffle 120 through the cooperation of the holes and the shaft. Figure 4As shown, the fitting member 222 is configured as a screw rod, which includes a first threaded segment 2221, a shaft segment 2222 and a second threaded segment 2223 connected in sequence, the first segment 220a is threadedly connected to the first threaded segment 2221 through the first screw hole 220a1, and the third segment 220c is threadedly connected to the second threaded segment 2223 through the second screw hole 220c1. In this way, the first segment 220a can be rotated by itself and moved relative to the length direction of the screw rod through the threaded cooperation of the first screw hole 220a1 and the first threaded segment 2221, and similarly, the third segment 220c can also be rotated by itself and moved relative to the length direction of the screw rod through the threaded cooperation of the second screw hole 220c1 and the second threaded segment 2223, that is, it can be understood that when the first segment 220a and the third segment 220c are both in a stationary state, the first threaded segment 2221 and the second threaded segment 2223 can also be driven to rotate by rotating the shaft segment 2222, and the first segment 220a and the third segment 220c can also be moved relative to the second segment 220b, thereby adjusting the overall length of the locking assembly 220 to facilitate connection and locking with the mounting holes at different positions on the baffle 120.
[0038] It should be noted that the shaft segment 2222 mentioned in the above embodiments can be an axis body of any shape with a smooth surface, for example, in the embodiment shown in the drawings, the shaft segment 2222 can be a cylindrical axis body. Figure 4 In the embodiment shown, the shaft segment 2222 can be a cylindrical axis body, after the mounting hole on the baffle 120 of the drum 1 is connected and locked by the locking member 221 on the third segment 220c, the first segment 220a and the third segment 220c can be moved along the length direction of the second segment 220b by rotating the shaft segment 2222, so as to tension the entire locking assembly 220, thereby stably limiting the drum 1, or in the case that the staff cannot manually rotate the shaft segment 2222, an external tool such as a wrench can also be used to clamp and rotate the shaft segment 2222, and when the locking member 221 is not connected to the mounting hole, the overall length of the first segment 220a, the second segment 220b and the third segment 220c can be adjusted in advance by rotating the shaft segment 2222, so that the locking member 221 can be connected to the mounting hole to limit the rotation of the drum 1.
[0039] In addition, in order to facilitate the rotation of the shaft segment 2222 by the external tool, the shaft segment 2222 can also be a polygonal segment with a plurality of face body side walls, for example, the shaft segment 2222 can be a multi-face shaft segment with a polygonal (e.g. hexagonal) cross section, so that the shaft segment 2222 can be more easily clamped by the external tool to rotate the shaft segment 2222 more easily, which is not limited in the present disclosure.
[0040] In some embodiments, with reference toFigure 4 As shown, the first threaded segment 2221 and the second threaded segment 2223 are opposite in the rotation direction. In this way, the first threaded segment 2221 and the second threaded segment 2223 opposite in the rotation direction can jointly drive the first segment 220a and the third segment 220c to approach or move away from the second segment 220b when the second segment 220b rotates in the same direction, so as to more conveniently adjust the overall length of the locking assembly 220 itself, and more flexibly connect to the mounting holes at different positions of the baffle 120. It should be noted that the rotation direction of the threads of the first threaded segment 2221 and the second threaded segment 2223 only needs to be opposite, that is, the second segment 220b can drive the first segment 220a and the third segment 220c to approach the second segment 220b when rotating clockwise, and drive the first segment 220a and the third segment 220c to move away from the second segment 220b when rotating counterclockwise; or the second segment 220b can drive the first segment 220a and the third segment 220c to approach the second segment 220b when rotating counterclockwise, and drive the first segment 220a and the third segment 220c to move away from the second segment 220b when rotating clockwise. The above two methods can achieve the length direction movement of the first segment 220a and the third segment 220c relative to the second segment 220b, and the present disclosure does not make specific limitations thereon.
[0041] In some embodiments, with reference to Figures 1 to 4 As shown, the base 210 includes a base table 211 and a rotating shaft 212 arranged on the surface of the base table 211, and the first segment 220a is rotationally connected to the rotating shaft 212.

In addition, the connection mode of the first segment 220a and the rotating shaft 212 can also refer to the connection mode of the locking member 221 and the baffle 120 in the above specific embodiments, that is, the first segment 220a can also include two connecting plates 2212, and the two connecting plates 2212 are provided with mounting holes. After aligning the two mounting holes and the rotating shaft 212 to the coaxial position, the limiting rod 2211 can pass through the two mounting holes and the rotating shaft 212, and the two nuts are threadedly connected to the limiting rod 2211 and abut against the side of the two connecting plates 2212 away from the rotating shaft, so as to realize the connection of the first segment 220a and the rotating shaft 212.
[0042] In some embodiments, with reference to Figures 1 to 4As shown, the base 211 is provided with a plurality of positioning holes 2111, which are arranged at intervals on the base 211. In this way, the base 211 can be connected to the ground or a mounting table of a factory or the like by means of cooperation with fasteners, for example, a plurality of threaded holes can be pre-drilled on the ground or the mounting table of the factory, and a plurality of anchor bolts can be screwed into the plurality of threaded holes through the plurality of positioning holes 2111, so as to fix the base 211.

In this way, the drum can be rotated by the driving of the motor, and in turn can drive the steel wire rope to be wound or lowered, and in turn can drive the material suspended at the other end of the steel wire rope to move and transport in the height direction. After the material is transported to the position, the locking assembly 220 of the drum limiting device can be connected to the matching part 121 on the baffle 120 of the drum 1, so as to limit and fix the circumference of the drum 1.
