[0022] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0023] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0024] During the installation of hydraulic cylinders, positioning is required. Traditionally, hand-operated hoists are used for this purpose. However, the instability of hand-operated hoists easily leads to positioning errors, failing to meet operational requirements. Furthermore, repeated rework delays and wastes significant time, hindering subsequent processes. Therefore, a fixture is needed to position the hydraulic cylinders accurately, improving installation precision and reducing wasted time.

[0025] In response, this application proposes a positioning device 100, which is described below with reference to the appendix. Figure 1-2 The positioning device 100 of the present application is described.

[0026] like Figure 1 As shown, the positioning device 100 according to an embodiment of this application includes: a screw jack 10, a clamping device 20, and a positioning bolt 30.

[0027] The clamping device 20 includes a base plate 21 and a side plate. The base plate 21 is connected to the output end of the screw jack 10. The side plate is connected to the base plate 21 and defines a clamping space 24 with the base plate 21. The positioning bolts 30 pass through the side plate and are threadedly engaged with the side plate. Multiple positioning bolts 30 are provided, and the multiple positioning bolts 30 are arranged around the clamping space 24.

[0028] For example, the screw jack 10 can be in models such as QL20 and QLD low-profile. The QL20 screw jack 10 is available in specifications such as 3 tons, 5 tons, 10 tons, 16 tons, 20 tons, 25 tons, 32 tons, 50 tons, 100 tons, 200 tons, 320 tons, and 380 tons.

[0029] Understandably, the large weight of the screw jack 10 prevents wobbling during the positioning process of the hydraulic cylinder 200, thus improving installation accuracy.

[0030] Furthermore, the hydraulic cylinder 200 can be placed in the clamping space 24. At this time, the hydraulic cylinder 200 can sit on the base plate 21. The side plate can be configured to surround the hydraulic cylinder 200 or surround part of the hydraulic cylinder 200. In this way, the side plate can protect the hydraulic cylinder 200 from the side.

[0031] Furthermore, the positioning bolt 30 can be vertically inserted into the side plate and threaded with the side plate. When the positioning bolt 30 rotates, the rotation of the positioning bolt 30 will enable the positioning bolt 30 to move linearly along its own axis, so that the positioning bolt 30 can move closer to or away from the center of the clamping space 24, thereby clamping or releasing the hydraulic cylinder 200, and thus positioning the hydraulic cylinder 200.

[0032] Furthermore, multiple positioning bolts 30 are arranged around the clamping space 24, so that the multiple positioning bolts 30 can position the hydraulic cylinder 200 at different positions in the circumferential direction, thereby improving the positioning stability of the hydraulic cylinder 200.

[0033] According to the positioning device 100 of the present application embodiment, since the self-weight of the screw jack 10 is large, it prevents the shaking problem of the hydraulic cylinder 200 during the positioning process, which is conducive to increasing the installation accuracy. Moreover, the multiple positioning bolts 30 can position the hydraulic cylinder 200 at different positions in the circumferential direction, thereby facilitating the improvement of the positioning stability of the hydraulic cylinder 200.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, at least two of the multiple positioning bolts 30 are arranged opposite to each other. In this way, the at least two oppositely arranged positioning bolts 30 can position the hydraulic cylinder 200 in two directions opposite to each other, thereby improving the positioning stability of the hydraulic cylinder 200.

[0035] In some embodiments, such as Figure 1 As shown, the clamping space 24 is provided with an opening 25, and the opening 25 is defined by the end of the side plate away from the bottom plate 21. In this way, the hydraulic cylinder 200 can be placed into the clamping space 24 through the opening 25, or the hydraulic cylinder 200 can be removed from the clamping space 24.

[0036] In some embodiments, such as Figure 1 As shown, the distance between the positioning bolt 30 and the bottom plate 21 is greater than the distance between the positioning bolt 30 and the opening 25. This brings the positioning bolt 30 closer to the opening 25, thereby improving the positioning effect on the upper part of the hydraulic cylinder 200.

[0037] In some embodiments, the side panel includes a first side panel 22 and a second side panel 23, such as Figure 1 and Figure 2 As shown, the first side plate 22 and the second side plate 23 are respectively connected to the two ends of the bottom plate 21 that are opposite to each other, and both the first side plate 22 and the second side plate 23 are provided with positioning bolts 30.

[0038] In this way, the first side plate 22 and the second side plate 23 can protect the oil cylinder 200 on opposite sides, and both the first side plate 22 and the second side plate 23 are provided with positioning bolts 30 so as to position the oil cylinder 200 on opposite sides.

[0039] In some embodiments, the distance from the first side plate 22 to the screw jack 10 is the same as the distance from the second side plate 23 to the screw jack 10. This ensures that the first side plate 22 and the second side plate 23 are at the same distance from the screw jack 10, thereby facilitating the balance of the first side plate 22 and the second side plate 23 on both sides of the screw jack 10.

[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the first side plate 22 and the second side plate 23 are arranged opposite to each other. This allows the first side plate 22 and the second side plate 23 to protect the hydraulic cylinder 200 from opposite sides.

[0041] In some embodiments, such as Figure 2 As shown, both the first side plate 22 and the second side plate 23 are provided with two positioning bolts 30. This facilitates the positioning of the hydraulic cylinder 200 by using multiple positioning bolts 30, thereby enhancing the positioning effect of the hydraulic cylinder 200.

[0042] In some embodiments, the distance between the two positioning bolts 30 located on the first side plate 22 is a first distance, and the distance between the two positioning bolts 30 located on the second side plate 23 is a second distance, wherein the first distance is greater than or equal to the second distance.

[0043] For example, the first distance is greater than the second distance, so that the line connecting the two positioning bolts 30 on the first side plate 22 and the two positioning bolts 30 on the second side plate 23 can form a trapezoid, thereby enhancing the positioning effect of the hydraulic cylinder 200.

[0044] Alternatively, the first distance can be equal to the second distance, so that the two positioning bolts 30 on the first side plate 22 and the two positioning bolts 30 on the second side plate 23 are symmetrically arranged, thereby enhancing the positioning effect of the hydraulic cylinder 200.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the positioning bolt 30 includes a screw 31 and a nut 32. The screw 31 passes through the side plate and is threaded into the side plate. The nut 32 is connected to the screw 31 and is located outside the clamping space 24.

[0046] This allows employees to rotate the nut 32 from the outside of the clamping space 24, thereby rotating the bolt and displacing the screw 31 in its own axial direction, thus clamping or releasing the cylinder 200.
