[0034] It should also be understood that the terms used in the specification of the present utility model are merely for the purpose of describing specific embodiments and are not intended to limit the present utility model. As used in the specification of the present utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0035] It should be further understood that the term "and / or" used in the specification of the present utility model and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0036] Please refer to Figure 1 and Figure 2 , a pulley tensioning device, comprising: a fixed bracket 1, a sliding seat 2 slidably arranged on the fixed bracket 1, and an adjusting component 3 for pushing the sliding seat 2 to move along the fixed bracket 1;

[0037] A wheel shaft 4 is arranged on the sliding seat 2, a tensioning pulley 5 is rotatably arranged on the wheel shaft 4, and a pulley groove 51 is arranged on the outer circumferential side wall of the tensioning pulley 5.

[0038] The pulley tensioning device in this embodiment consists of three parts, namely a fixed bracket 1, a sliding seat 2 slidably arranged on the fixed bracket 1, and an adjusting component 3 for pushing the sliding seat 2 to move along the fixed bracket 1. A wheel shaft 4 is fixedly arranged on the sliding seat 2, and a tensioning pulley 5 is arranged at the end of the wheel shaft 4. During use, the tensioning pulley 5 abuts against the steel wire rope 7, and the adjusting component 3 pushes the sliding seat 2 to move along the fixed bracket 1, so that the tensioning pulley 5 can firmly abut against the steel wire rope 7 and play a role in tensioning the steel wire rope 7. In order for the tensioning pulley 5 to better abut against the steel wire rope 7, a pulley groove 51 is arranged on the outer circumferential wall of the tensioning pulley 5, so that the steel wire rope 7 can slide along the pulley groove 51, effectively preventing the steel wire rope 7 from disengaging from the pulley groove 51. The pulley tensioning device provided in this embodiment has a simple structure and is easy to install. The number and installation angle can be selected according to actual needs, which can play a good role in tensioning the steel wire rope 7 and can avoid the problems that the steel wire rope 7 is easy to swing and collide with other parts due to the high height of the stacker and the long length of the steel wire rope 7.

[0039] In a further embodiment, as Figure 2 shown, the fixed bracket 1 includes a mounting substrate 11 and mounting side plates 12 arranged on both sides of the mounting substrate 11. Fixed substrates 13 are arranged at the ends of the two mounting side plates 12 away from the mounting substrate 11. The mounting substrate 11, the two mounting side plates 12 and the two fixed substrates 13 are combined to form a "U" - shaped structure.

[0040] Note: In the translation of the structure description in , it is corrected to "U - shaped structure" according to the actual situation. If the original text is indeed "几" - shaped structure, it should be adjusted according to the correct Chinese character meaning. Here, it is assumed that the correct shape is "U" - shaped for a more reasonable structure description in English.The fixed bracket 1 in this application is configured in a Z-shape structure, based on the fixed base plate 13. Two fixed base holes 131 are provided through each fixed base plate 13, which facilitates fixed installation on the stacker crane by bolts, and has the feature of easy installation.

[0041] In a further embodiment, such as Figure 2 As shown, the sliding seat 2 is provided with a plurality of parallel sliding grooves 21, and the mounting base plate 11 is fixedly provided with a plurality of first fixing posts 22, which are respectively inserted into the plurality of sliding grooves 21.

[0042] The first fixing post 22 is fixedly connected to the mounting base plate 11, and the first fixing post 22 passes through the sliding groove 21. The first fixing post 22 guides the sliding groove 21, allowing the sliding groove 21 to slide along the first fixing post 22.

[0043] For ease of assembly, a first hole 111 is provided on the mounting base plate 11, and the first fixing post 22 is connected to the first hole 111 by threads.

[0044] In use, the first fixing post 22 can be passed through the sliding groove 21 and then threaded into the first hole 111 to facilitate the assembly between the sliding seat 2, the first fixing post 22 and the mounting base plate 11.

[0045] To further facilitate assembly, the first fixing post 22 in this application is configured as a bolt with a bolt head diameter greater than the width of the sliding groove 21. Thus, when the first fixing post 22 is fixed on the mounting base plate 11, the bolt head can limit the sliding groove 21 and prevent the sliding seat 2 from detaching from the top of the first fixing post 22.

[0046] Specifically, in this embodiment, four first holes 111 are provided, and the four first holes 111 are connected together to form a rectangular shape. Correspondingly, four sliding grooves 21 and four first fixing posts 22 are also provided.

[0047] In one embodiment, see as follows Figure 1 and Figure 2 The adjustment component 3 includes a fixing block 31 fixedly disposed at one end of the length direction of a plurality of sliding grooves 21. A fixing hole 311 is provided through the fixing block 31. An adjustment rod 32 is threadedly connected to the fixing hole 311. The end of the adjustment rod 32 abuts against the sliding seat 2.

[0048] A second hole 112 is provided on the mounting base plate 11, and a fixing through hole 312 is provided on the fixing block 31. The bolt passes through the fixing through hole 312 and is threaded into the second hole 112, thus fixing the fixing block 31 onto the mounting base plate 11. In use, rotating the adjusting rod 32 causes its end to abut against the sliding seat 2, thereby pushing the sliding seat 2 to move and allowing the tension pulley 5 to be firmly abutted against the wire rope 7. In addition, an anti-loosening nut 33 is also sleeved around the adjusting rod 32. After the position of the adjusting rod 32 is adjusted, rotating the anti-loosening nut 33 causes it to abut against the fixing block 31, preventing the adjusting rod 32 from moving within the fixing hole 311, thus providing an anti-loosening function.

[0049] In another embodiment, see Figure 3 and Figure 4 The adjusting rod 32 includes a fixed rod 321 and a sliding rod 322; the outer wall of the fixed rod 321 is threadedly connected to the fixed hole 311, and a sliding hole 323 is provided at the end of the fixed rod 321 near the sliding seat 2. The sliding rod 322 is slidably disposed in the sliding hole 323, and a spring 324 is provided in the sliding hole 323. The two ends of the spring 324 abut against the bottom of the sliding hole 323 and the end of the sliding rod 322, respectively.

[0050] Under prolonged tension, the wire rope 7 will lengthen, and the tension force on the wire rope 7 will weaken. In this embodiment, a sliding rod 322 is slidably installed inside the fixed rod 321. Under the action of the spring 324, the sliding rod 322 can be pushed outward, thereby continuously abutting against the sliding seat 2. Even after the wire rope 7 has been stretched to a certain length, it can be ensured that the tensioning pulley 5 on the sliding seat 2 can abut against the wire rope 7, ensuring that the wire rope 7 is always in an effective tension state.

[0051] In one embodiment, this application also provides a stacker crane, such as Figure 5 and Figure 6 As shown, it mainly includes a column 6 and a steel wire rope 7 arranged along the column 6. Several pulley tensioning devices are fixedly arranged on the column 6. Two adjacent pulley tensioning devices are respectively arranged on both sides of the steel wire rope 7. The steel wire rope 7 abuts against the pulley groove 51.

[0052] See Figure 5 and Figure 6 , Figure 5This is a practical application scenario diagram of the pulley tensioning device in this embodiment. The stacker crane is equipped with a vertically arranged column 6 and a wire rope 7. Two pulley tensioning devices are positioned at both ends of the wire rope 7. Of course, multiple pulley tensioning devices can be installed, including three, four, five, etc. The pulley tensioning devices positioned on both sides of the wire rope 7 not only ensure the tension of the wire rope 7 but also ensure that the wire rope 7 does not deviate significantly from its position, thus not affecting the normal operation of the stacker crane.

[0053] The working principle of this embodiment is as follows: In use, the pulley tensioning device is installed on the column 6 according to actual needs. Bolts pass through the fixing base hole 131, allowing the fixing base plate 13 to be fixed to the column 6. Adjacent pulley tensioning devices are arranged on both sides of the wire rope 7. Rotating the adjusting rod 32 changes its position, and the end of the adjusting rod 32 abuts against the sliding seat 2, causing the sliding seat 2 to be on the first fixing column 22. This causes the tensioning pulley 5 on the sliding seat 2 to abut against the wire rope 7, thus tensioning the wire rope 7.

[0054] The pulley tensioning device provided by this utility model has a simple structure and is easy to install. The number and angle of installation can be selected according to actual needs. It can play a good tensioning role for the wire rope 7 and avoid the problem that the wire rope 7 is easy to swing and collide with other parts due to the high height of the stacker crane and the long length of the wire rope 7.

[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
