Description

Technical Field

[0001] The utility model relates to the technical field of hanging type storage racks, in particular to a hanging rope length adjusting device for a hanging rope storage rack. Background Art

[0002] Rope racks are also called ceiling racks. Generally, the ropes are installed on the ceiling of the room with fixings. The bottom of the ropes are connected to several corners of the storage board, such as the four corners of the rectangular storage board. Some can also use manual drive devices or electric drive devices to drive the storage board to rise or fall to facilitate the placement or retrieval of objects. The rope racks have been widely promoted and applied because they can reasonably utilize the height space in the room.

[0003] However, when the rope storage rack of the prior art is in use, errors often occur in the heights of several corners of the storage board, such as the four corners of the rectangular storage board, such as a difference of 10-30 mm, etc., due to different long-term forces on several ropes such as steel wire ropes, or differences in the fatigue strength of the ropes themselves such as steel wire ropes, resulting in the storage boards of the rope storage rack not being on the same horizontal plane.

[0004] When the above phenomenon occurs, the existing technical solutions all need to be solved from the end of the rope. Generally, the end fixing parts of the rope, such as the end lock buckle of the wire rope, are disassembled, and then the length of the longer rope, such as the wire rope, is shortened to make the lengths of several ropes, such as the wire rope, basically equal, and then the end fixing parts of the rope, such as the end lock buckle of the wire rope, are re-fixed to roughly maintain the horizontality of the storage board. The above-mentioned removal and re-fixing process of the ends of the ropes, especially the ends of the wire ropes, are very difficult and laborious, and each adjustment and fixation will cause damage to the fixed section of the rope, such as the wire rope, leaving a safety hazard. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a hanging rope length adjusting device for a hanging rope storage rack, which is convenient and labor-saving in adjusting the hanging rope length and will not cause damage to the hanging rope.

[0006] The technical solution of the utility model is to provide a rope length adjustment device for a rope storage rack, comprising a shell composed of a main body and a cover body detachably connected; the rope includes a force rope; the upper end and the lower end of the shell are both provided with openings through which the force rope passes, and the shell is provided with at least one arc-shaped placement groove for the force rope, which is connected to the opening through which the force rope passes and is used to shorten the straight-line distance between the upper end surface and the lower end surface of the shell when the force rope enters the shell.

[0007] After adopting the above structure, the rope length adjustment device of the rope storage rack of the utility model has the following advantages: it is not difficult to understand that the straight-line distance between the upper end face and the lower end face of the shell is the shortest, and the arc distance is longer than the straight-line distance. The utility model utilizes this principle. If the length of one or several relatively long force ropes such as steel wire ropes among several ropes is shortened, so that the lengths of several ropes such as steel wire ropes are basically equal, and the storage plate of the storage rack is roughly maintained on the same horizontal plane, it is not necessary to disassemble the end fixing parts of the rope such as the end lock of the steel wire rope as in the prior art, and then re-tighten the end fixing parts such as the end lock of the steel wire rope after shortening the length. Instead, it is only necessary to place each force rope that needs to be shortened, such as any section of each force steel wire rope, in the arc-shaped placement groove of a force rope of the device, and then detachably fix the main body and the cover body, such as by bolts and nuts. Moreover, it is not difficult to understand that, according to the application practice, an arc-shaped placement groove of the force rope that can shorten the force rope to different straight-line distances between the upper end face and the lower end face of the shell can be designed, and a plurality of rope length adjustment devices of the rope storage rack that adapt to various shortening distances or size requirements can be manufactured. According to the length of the force rope that needs to be shortened to different straight-line distances or different sizes, such as the length of the force wire rope, the rope length adjustment devices of different distances or sizes are selected. The rope length adjustment device of the rope storage rack makes it convenient and labor-saving to adjust the length of the rope, such as the force rope, and will not cause damage to the force rope, such as the force wire rope, thereby avoiding possible safety hazards.

[0008] Furthermore, the arc-shaped groove of the force rope is used to shorten the straight-line distance between the upper end face and the lower end face of the shell to multiple paths of different sizes. With the above structure, the same suspension rope length adjustment device can meet the needs of adjusting the length of the force rope to several different straight-line distances or different length sizes, such as two or three different straight-line distances, further ensuring the technical effect of making the length adjustment of the suspension rope such as the force rope convenient and labor-saving.

[0009] Furthermore, the lifting rope also includes a spare rope; both upper and lower ends of the shell have openings through which the spare rope passes, and the shell also has one or more arc-shaped slots for the spare rope that are connected to the openings through which the spare rope passes and are used to shorten the straight-line distance between the upper end face and the lower end face of the shell when the spare rope enters the shell. In the actual structure of the lifting rope rack, some of the lifting ropes include a set of spare ropes such as spare steel wire ropes in addition to the force-bearing ropes such as the force-bearing steel wire ropes for the sake of greater security and safety. The connection relationship of the spare ropes is the same as that of the force-bearing ropes. If lifting is required, the spare ropes can also be used for lifting, but the spare ropes are generally not subjected to force during use and only serve as a spare. If one or several force-bearing ropes break due to various reasons, the spare ropes can still ensure safety. After the utility model adopts the above structure, when the lifting rope rack has a spare rope, the length adjustment of the spare rope, i.e., the straight-line distance adjustment, is also convenient and labor-saving, and will not cause damage to the spare ropes such as the spare steel wire ropes, thereby avoiding possible safety hazards. The technical effect of making the length adjustment of the suspension rope convenient and labor-saving, not causing damage to the suspension rope such as a wire rope, and avoiding possible safety hazards is further ensured.

[0010] Furthermore, the two sides of the shell are arranged symmetrically; the width of the upper end and the lower end of the shell are both smaller than the width of the middle of the shell height; the shell is arranged symmetrically from top to bottom. With the above structure, the length adjustment space of the arc-shaped mounting groove in the shell can be larger, and each turning point of the arc-shaped mounting groove in the shell, including the arc-shaped mounting groove of the force rope and the arc-shaped mounting groove of the spare rope, is arc-shaped, which further ensures that the length adjustment of the suspension rope is convenient and labor-saving, does not cause damage to the suspension rope such as the wire rope, avoids possible safety hazards, and has a more solid and reliable connection.

[0011] Furthermore, one or more arc-shaped placement grooves are arranged inside the body. After adopting the above structure, if the linear distance of one or more relatively long suspension ropes needs to be shortened, it is only necessary to place the suspension rope to be adjusted, such as any section of the wire rope, in a certain arc-shaped placement groove of the body, such as placing a force-bearing rope in the arc-shaped placement groove of the force-bearing rope of the body, placing a spare rope in the arc-shaped placement groove of the spare rope of the body, and then cover the cover body, and then tighten the cover body and the body, such as by screwing and fixing with multiple sets of bolts and nuts, which further ensures the technical effect of making the suspension rope length adjustment convenient and labor-saving and the connection more firm and reliable.

[0012] Furthermore, the multiple arc-shaped grooves on each side are separated from each other by continuous arc-shaped convex ribs. With the above structure, a relatively long force rope such as a force wire rope or a relatively long spare rope such as a spare wire rope can be shortened to different straight-line distances or different lengths by one main body, and the structure of the device is more solid and reliable.

[0013] Furthermore, the detachable connection is achieved by screwing multiple sets of bolts and nuts. After the detachable connection adopts the above specific structure, the detachable connection between the main body and the cover is convenient and labor-saving, and the connection is firm and reliable.

[0022] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these specific implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each specific implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown.

[0024] The rope storage rack 1 of the prior art is also called a ceiling storage rack. Generally, a fixing member 11 is used to install a rope 12 on the indoor ceiling. The bottom end of the rope 12 is connected to several corners of a storage board 13, such as the four corners of a rectangular storage board. A manual drive device 14 or an electric drive device can also be used to drive the storage board 13 to rise or fall for the convenience of placing or taking out objects. For the sake of greater security and safety, the rope 12 includes a set of force ropes 121, such as a force wire rope, and a set of spare ropes 122, such as a spare wire rope. The connection relationship of the spare rope 122 is the same as that of the force rope 121. The spare rope 122 can also be used to rise or fall the storage board 13. However, the spare rope 122 is generally not subjected to force during use and only serves as a backup. If one or several force ropes 121 break due to various reasons, the spare rope 122 can still ensure safety. When the above prior art rope rack 1 is used, the height of several corners of the storage plate 13, such as the four corners of the rectangular storage plate, often has errors, such as a difference of 10-30 mm, etc., due to the different long-term stress of several ropes 12, such as several steel wire ropes, or the fatigue strength of the ropes 12 themselves, such as the steel wire ropes themselves. As a result, the storage plate 13 of the rope rack 1 is not on the same horizontal plane, and it is necessary to adjust the relatively long one or two force ropes 121 in the rope 12 and the one or two spare ropes 122 that cooperate with each other to shorten their lengths relatively, so as to make the lengths of several ropes 12, such as steel wire ropes, basically equal, so that the storage plate 13 of the rope rack 1 is roughly maintained on the same horizontal plane. It is not difficult to understand that the rope 12 can be nylon ropes and other fiber ropes such as hemp ropes, palm ropes, etc. in addition to steel wire ropes.

[0025] The rope length adjustment device of the rope storage rack of the utility model comprises a shell 2 which is detachably connected to a main body 21 and a cover body 22. The rope 12 comprises a force rope 121. The upper and lower ends of the shell 2 are provided with openings 213 through which the force rope passes, such as the opening 213 through which the force rope passes provided at the upper end of the main body 21 and the opening 213 through which the force rope passes provided at the lower end of the main body 21. The shell 2 is provided with at least one arc-shaped force rope placement groove 214 which is in communication with the opening 213 through which the force rope passes and is used to shorten the straight-line distance between the upper end surface 23 and the lower end surface 24 of the force rope 121 entering the shell 2.

[0026] The arc-shaped groove of the force rope 121 is preferably used to shorten the straight-line distance between the upper end surface 23 and the lower end surface 24 of the shell of the force rope 121 to multiple paths of different sizes. Figure 5 The two arc-shaped grooves 2141 and the outer arc-shaped grooves 2142 on the left side of the main body 21 can be arranged on the main body 21, or three arc-shaped grooves 2141 and 2142 can be arranged on the left side of the main body 21. The length of the arc-shaped grooves 214 that can shorten the length of the force rope 121 can also be flexibly designed. For example, a 100 mm long force rope 121 such as a force wire rope can be placed in the arc-shaped grooves 214. Figure 5 The inner arc of the left side of the main body 21 on the right side is placed in the groove 2141, so that the section of the force rope, such as the force wire rope, is shortened to a straight line distance of 90mm between the upper end surface 23 and the lower end surface 24 of the housing 2. For example, a section of the force rope 121, such as the force wire rope, with a length of 100mm can be placed in Figure 5 The outer arc-shaped placement groove 2142 of the stress-bearing rope on the left side of the main body 21 on the left side of the middle body 21 is shortened to a straight line distance of 80 mm between the upper end surface 23 and the lower end surface 23 of the housing 2. For another example, a stress-bearing rope such as a stress-bearing wire rope with a length of 100 mm can be placed in the arc-shaped placement groove of the third stress-bearing rope on the left side away from the center of the housing, which is not shown in the figure, and shortened to a straight line distance of 70 mm between the upper end surface and the lower end surface of the housing.

[0027] The lifting rope 12 also includes a spare rope 122. There are also openings 216 for the spare rope to pass through at the upper and lower ends of the shell 2, such as the opening 216 for the spare rope to pass through provided at the upper end of the main body 21 and the opening 216 for the spare rope to pass through provided at the lower end of the main body 21. There is also one or more arc-shaped grooves 215 for the spare rope in the shell 2, which are connected to the openings 216 for the spare rope to pass through and are used to shorten the straight-line distance between the upper end surface 23 and the lower end surface 24 of the shell 2 for the spare rope 122 entering the shell 2. It is not difficult to understand that in the shell 2, the spare rope 122 and the force-bearing rope 121 are symmetrically arranged. The arc-shaped groove 215 for the spare rope can be as follows: Figure 5The two arc-shaped slots 2151 and 2152 of the spare rope on the right side of the main body 21 can be used as shown in the figure. The length of the spare rope 122 that can be shortened by each arc-shaped slot 215 can also be flexibly designed. For example, a 100mm long spare rope 122 such as a spare steel wire rope can be placed in the slot 2151. Figure 5 The spare rope on the right side of the right body 21 is placed in the inner arc shape groove 2151, so that the spare rope 122 such as spare steel wire rope is shortened to a straight line distance of 90mm between the upper end surface 23 and the lower end surface 24 of the housing 2. For example, a 100mm long spare rope such as spare steel wire rope can be placed in Figure 5 The outer arc-shaped placement groove 2152 of the right spare rope of the left body 21 in the middle makes the section of spare rope 122, such as spare steel wire rope, shorten to 80mm in straight line distance between the upper end surface 23 and the lower end surface 24 of the housing 2. For another example, a section of spare rope, such as spare steel wire rope, with a length of 100mm can be placed in the arc-shaped placement groove of the third spare rope, i.e., the outermost spare rope, away from the center of the body, which is not shown in the figure, so that the section of spare rope is shortened to 70mm in straight line distance between the upper end surface and the lower end surface of the housing.

[0028] The outer ends of the opening 213 through which the force rope passes and the opening 216 through which the backup rope passes may be provided with chamfers or arc angles.

[0029] The two sides of the shell 2 are preferably arranged symmetrically, the width of the upper end and the lower end of the shell 2 are preferably smaller than the width of the middle of the height of the shell 2, and the shell 2 is preferably arranged symmetrically from top to bottom. This paragraph can be understood as follows: the two sides of the body 21 are preferably arranged symmetrically, the width of the upper end and the lower end of the body 21 are preferably smaller than the width of the middle of the height of the body 21, and the body 21 is preferably arranged symmetrically from top to bottom. The two sides of the cover 22 are preferably arranged symmetrically, and the width of the upper end and the lower end of the cover 22 are preferably smaller than the width of the middle of the height of the cover 22. The cover 22 is preferably arranged symmetrically from top to bottom.

[0030] It is easy to understand that the upper end surface 23 of the shell 2 is the upper end surface of the body 21 and the upper end surface of the cover 22, and the lower end surface of the shell 2 is the lower end surface of the body 21 and the lower end surface of the cover.

[0031] As described above, one or more arc-shaped receiving grooves are preferably arranged on the inner surface of the main body 21, that is, one or more arc-shaped receiving grooves 214 for the force-bearing ropes are preferably arranged on the inner surface of the main body 21, and one or more arc-shaped receiving grooves 215 for the spare ropes are also preferably arranged on the inner surface of the main body 21.

[0032] The inner surface of the cover 22 may be provided with an inner convex pressure plate 223 for pressing the suspension ropes 12 such as the force rope 121 and the spare rope 122 contained in the arc-shaped receiving groove. Of course, the inner surface of the cover may also be a plane, which can also press the suspension ropes such as the force rope and the spare rope contained in the arc-shaped receiving groove. The arc-shaped receiving groove is also called an arc-shaped receiving groove.

[0033] Of course, as a variation, one or more arc-shaped placement grooves, such as one or more arc-shaped placement grooves for force-bearing ropes and one or more arc-shaped placement grooves for spare ropes, can also be set inside the cover body, and the body can serve as a pressure plate.

[0034] As a variation, one or more arc-shaped mounting grooves, such as one or more arc-shaped mounting grooves for force-bearing ropes and one or more arc-shaped mounting grooves for spare ropes, can also be arranged half inside the main body and the cover. After the main body and the cover are screwed together by fasteners such as a fastening bolt and nut structure or a fastening screw structure, the lifting ropes such as the force-bearing rope and the spare rope are compressed and fixed.

[0035] The multiple arc-shaped placement grooves on each side are preferably separated from each other by continuous arc-shaped convex ribs 217. Of course, the arc-shaped convex ribs can also be discontinuous instead of continuous. Both ends of the continuous arc-shaped convex ribs 217 can be provided with chamfers or arc angles 2171, and both ends of the discontinuous arc-shaped convex ribs 217 can also be provided with chamfers or arc angles, which is more conducive to the placement of the suspension rope 12 such as a wire rope.

[0036] The detachable connection preferably adopts multiple sets of bolts and nuts for screw connection. The specific structure of each set of bolts and nuts for screw connection can be: bolt holes are provided on the body 21 and the cover body 22, such as the bolt holes on the body 21 are called first bolt holes 211, and the bolt holes on the cover body 22 are called second bolt holes 221. The bolt holes can be countersunk holes with large outside and small inside. The large hole, i.e., the outer hole, of the countersunk hole of the body 21 can be a regular hexagonal hole 212 for accommodating a regular hexagonal nut, and the large hole, i.e., the outer hole, of the countersunk hole of the cover body 22 can be a round hole 222 for accommodating a round big head bolt with a hexagonal inner hole, and the round big head bolt with a hexagonal inner hole and a regular hexagonal nut are used for fastening.

[0037] The countersunk hole is used to make the appearance beautiful while facilitating fastening. Bolt through-hole columns can be provided at the bolt through-holes on the inner surface of the body 21 and the bolt through-holes on the inner surface of the cover 22 to increase the strength of the threaded holes and the strength of the housing 2. The bolt through-hole column on the inner surface of the body 21 can be called a first bolt through-hole column 219, and the bolt through-hole column on the inner surface of the cover 22 can be called a second bolt through-hole column 224.

[0038] The specific structure of the detachable connection can be varied in many ways. The large hole of the countersunk hole of the body, i.e., the outer hole, can be a circular hole for accommodating the large round head of a bolt with a hexagonal hole, and the large hole of the countersunk hole of the cover, i.e., the outer hole, can accommodate the regular hexagonal hole of a regular hexagonal nut. In addition to the above-mentioned bolt and nut screw connection structure, the detachable connection can also adopt multiple screw screw connections, such as multiple threaded holes on the body, multiple corresponding screw through holes on the cover, and multiple screws correspondingly pass through their respective screw through holes and are tightened in their respective threaded holes.

[0039] The rope length adjustment device of the rope rack of the utility model can also be called a rope tightener of the rope rack 1, such as a wire rope tightener of the rope rack 1. The force rope 121 can also be called a force rope, and the spare rope can also be called a spare rope. The upper end surface 23 of the main body 2 can be a plane, the lower end surface 24 can also be a plane, and the middle is an arc 25 that bulges outwards on both sides. An elliptical hole 26 can be provided in the middle of the shell 2. The elliptical hole 26 is not only a process hole, but also makes the appearance of the shell 2 more beautiful. An inner convex ring for increasing strength can be provided at the elliptical hole 26 on the inner surface of the main body 21, and a plurality of reinforcing ribs 218 can be provided between the elliptical inner convex ring and the continuous arc convex rib 217. Each first bolt through-hole column 219 can be connected to the elliptical inner convex ring and a continuous arc convex rib 217 to increase the strength of the main body 21.

[0040] The operation of the rope length adjustment device of the rope storage rack of the utility model is very simple. For example, it is only necessary to place any sections of a pair of ropes 12 whose vertical sections need to be shortened, such as a force rope 121 such as a force-bearing steel wire rope and a spare rope 122 such as a spare steel wire rope, in an arc-shaped placement groove 214 of the force rope and an arc-shaped placement groove 215 of the spare rope of the device, and then detachably connect the main body 21 and the cover body 22.

[0041] The above unmarked parts, structures or quantities are not shown in the drawings. The drawings are for illustration only. If there is any inconsistency between the drawings and the text description or between the drawings, the text description shall prevail.

[0042] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
