Description

Technical Field

[0001] This utility model relates to the field of scissor lift technology, specifically to a scissor lift with good stability. Background Technology

[0002] Scissor lifts are versatile aerial work platforms. Their scissor mechanism provides high stability during lifting, while their large working platform and high load capacity allow for a wider working range and suitability for multiple workers simultaneously. This results in higher work efficiency and enhanced safety.

[0003] Scissor lifts are classified into: fixed scissor lifts, mobile scissor lifts, self-propelled scissor lifts, vehicle-mounted scissor lifts, manually towed scissor lifts, and freight scissor lifts.

[0004] After long-term use, the applicant found that the existing scissor lift has a certain degree of swaying during the lifting process, which causes wear and misalignment at the pivot point. This exacerbates the swaying amplitude of the scissor lift and reduces its stability. The usual practice is to add shims for necessary compensation, but this is cumbersome. Utility Model Content

[0005] To address the issue of the aforementioned scissor lift mechanism exhibiting a certain degree of swaying during the lifting process, which leads to wear and misalignment at the pivot point over long-term use, this invention proposes a scissor lift with improved stability.

[0006] The technical solution of this utility model is achieved as follows: A scissor lift with good stability includes a base, a first connecting block, a long hinge rod, a short hinge rod, a second hinge block, and a load-bearing platform, characterized in that it further includes:

[0007] A long correction shaft is located at the end of the long hinge rod and is used to connect the long hinge rods on the front and rear sides.

[0008] A short correction shaft is disposed at one end of the short hinge rod, and the other end of the short hinge rod is hinged to the long correction shaft.

[0009] Furthermore, four first connecting blocks are fixedly connected to the top of the base. Each first connecting block is hinged with a long hinge rod. Multiple long hinge rods and multiple short hinge rods are connected to form a hinge frame. The top of the upper long hinge rod is hinged with a second hinge block. The top of the four second hinge blocks is fixedly connected with a bearing platform.

[0010] Furthermore, the long correction shaft includes a stabilizing shaft, both ends of which are provided with compensation components and outer sleeve shafts. A compensation screw brings the outer sleeve shaft close to the compensation components, and the compensation screw is threaded onto the stabilizing shaft.

[0011] Furthermore, the compensation component includes an abutment sleeve, which is fixed to the end of the stabilizing shaft by screws, and three work stations are sequentially arranged between the abutment sleeve and the outer shaft.

[0012] Furthermore, each of the three workstations includes a first gap compensation sleeve and a second gap compensation sleeve, with a compensation gap reserved between the first gap compensation sleeve and the second gap compensation sleeve.

[0013] Furthermore, the short correction shaft includes an insertion shaft, a fixing cap is provided at one end of the insertion shaft, an adjusting pad is provided on the insertion shaft, and a compression sleeve is fitted at the other end of the insertion shaft, the compression sleeve being restricted by an adjusting screw sleeve.

[0014] This utility model has the following beneficial effects:

[0015] 1. This scissor lift with good stability maintains stability during the lifting process through the first and second gap compensation sleeves, ensuring a reasonable gap between the long and short articulated rods or between two long articulated rods, reducing mechanical wear. The stabilizer bar keeps the load-bearing platform stable and reduces swaying.

[0016] 2. This stable scissor lift is easy to install and operate. When gaps occur, or when there is swaying between the long and short hinge rods during lifting, it can be adjusted in time. Moreover, the first gap compensation sleeve and the second gap compensation sleeve have the function of real-time gap compensation, which makes the lift stable and safe. Attached Figure Description

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 As shown, a scissor lift with good stability includes a base 1, a first connecting block 2, long hinge rods 3, short hinge rods 8, a second hinge block 4, and a carrying platform. Four first connecting blocks 2 are fixedly connected to the top of the base 1. Each first connecting block 2 is hinged with a long hinge rod 3. Multiple long hinge rods 3 and multiple short hinge rods 8 are connected to form a hinge frame. The top of the upper long hinge rod 3 is hinged to a second hinge block 4. The top of the four second hinge blocks 4 is fixedly connected to a carrying platform. The carrying platform has two connecting strips 5, and a loading plate 6 is provided between the two connecting strips 5. This is prior art and will not be described in detail.

[0023] like Figure 2 and Figure 4 The device also includes a long correction shaft 7, which is set at rotation points A, B, and C. The lifting frame has at least two rotation points A, B, and C. The long correction shaft 7 is set at the end of the long hinge rod 3 and is used to connect the long hinge rods 3 on the front and rear sides. The long correction shaft 7 includes a stabilizing shaft 71. Both ends of the stabilizing shaft 71 are provided with compensation parts 72 and outer sleeve shafts 74. The compensation screw 73 brings the outer sleeve shaft 74 close to the compensation parts 72, and the compensation screw 73 is threadedly connected to the stabilizing shaft 71.

[0024] The stabilizing shaft 71 is used to stabilize the lifting frames on both the front and rear sides, preventing the overall lifting platform from shaking during use.

[0025] The compensation component 72 includes an abutment sleeve 721, which is fixed to the end of the stabilizing shaft 71 by screws. The abutment sleeve 721 and the outer shaft 74 are sequentially provided with station one 722, station two 723 and station three 724.

[0026] Workstation 1 722, workstation 2 723 and workstation 3 724 all include a first gap compensation sleeve 7241 and a second gap compensation sleeve 7242, with a compensation gap 7243 reserved between the first gap compensation sleeve 7241 and the second gap compensation sleeve 7242.

[0027] Station 1 722 and Station 2 723 are the installation positions for two long hinge rods 3, respectively, and Station 3 724 is the installation position for a short hinge rod 8. Specifically, during installation, firstly, the abutment sleeve 721 is fixed on the stabilizing shaft 71, then the second gap compensation sleeve 7242 is fitted onto the stabilizing shaft 71, then the short hinge rod 8 is fitted onto the stabilizing shaft 71, then the first gap compensation sleeve 7241 and the second gap compensation sleeve 7242 are fitted onto the stabilizing shaft 71, then the two long hinge rods 3 are installed on the stabilizing shaft 71 in sequence, then the outer sleeve shaft 74 is fixed to the end of the stabilizing shaft 71, and then the compensation screw 73 is threaded onto the stabilizing shaft 71, so that after the outer sleeve shaft 74 abuts against the first gap compensation sleeve 7241, the two long hinge rods 3 and the short hinge rod 8 form an abutment state.

[0028] During long-term use, when a gap appears between the two long hinge rods 3 and the short hinge rod 8, the compensation screw 73 can be rotated to allow the outer sleeve shaft 74 to move axially in the stabilizer rod 71. This compresses the two long hinge rods 3 and the short hinge rod 8, thus compressing the compensation gap 7243 between the first gap compensation sleeve 7241 and the second gap compensation sleeve 7242. Consequently, when the lifting frame shakes, the stability of the lifting frame can be adjusted by the compensation screw 73, which is convenient and provides good stability.

[0029] The following description is made regarding the first gap compensation sleeve 7241 and the second gap compensation sleeve 7242:

[0030] All include a sleeve that moves axially on the stabilizer bar 71 and can rotate on the stabilizer bar 71, and a rubber pad fitted on the end of the sleeve. The rubber pad is used to maintain a reasonable gap between the long hinge rod 3 and the short hinge rod 8 or between the long hinge rod 3 and the long hinge rod 8. A metal sheet is embedded in the rubber pad to maintain the stability of the gap. The rubber pad is used to provide adjustment margin, and wear can be effectively controlled during the lifting process of the lifting frame.

[0031] like Figure 3 The short alignment shaft 9 shown is located at one end of the short hinge rod 8, and the other end of the short hinge rod 8 is hinged to the long alignment shaft 7. The short alignment shaft 9 includes an insertion shaft, a fixing cap at one end of the insertion shaft, an adjusting pad 91 on the insertion shaft, and a compression sleeve 92 fitted at the other end of the insertion shaft, which is restricted by an adjusting screw sleeve 93.

[0032] There are four adjusting pads 91 on the short correction shaft 9, arranged in pairs facing each other. The two adjusting pads 91 are respectively attached to the sides of the long hinge rod 3 and the short hinge rod 8. The adjusting screw sleeve 93 is used to abut the long hinge rod 3 and the short hinge rod 8 and make them firmly connected.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
