Description

Technical Field

[0001] The utility model belongs to the technical field of jacking devices, and in particular relates to a portable small-space tank jacking device. Background Art

[0002] During factory construction, large-scale tank construction, such as closed tanks and surge tanks, is a common occurrence. This is especially true when horizontal tanks require secondary grouting. Due to their typically large mass, installation and movement are difficult, often requiring auxiliary equipment such as cranes for positioning, movement, and fine-tuning. Not only is the machinery investment and costly, but manual movement can be difficult and may cause damage to the tank. Furthermore, large machinery is not feasible for many basement and indoor installations. Furthermore, tank foundations are typically limited in height, with small spacing between foundations, which often fails to meet operational requirements. Utility Model Content

[0003] In response to the above technical problems, the utility model provides a portable small-space tank jacking device, which occupies a small space and can adapt to jacking operations in a small space; and can be expanded / contracted and used and carried.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A portable small space tank jacking device includes a connecting assembly and a column assembly, wherein two column assemblies are provided and the two column assemblies are connected by a connecting assembly, the column assembly includes a column and a supporting top plate, a supporting rod is fixedly connected to the supporting top plate, the supporting rod is slidably connected to the column, a base is fixed to the bottom of the column, a first connecting groove is provided at the top of the column, and a second connecting groove opposite to the first connecting groove is provided at the bottom of the supporting top plate; the two ends of the jack are respectively connected to the first connecting groove and the second connecting groove.

[0006] A connecting slider is slidably connected to the column; the connecting assembly consists of two connecting rods hinged in the middle, the lower ends of the two connecting rods are hinged to the corresponding columns respectively, and the upper ends of the two connecting rods are hinged to the corresponding connecting sliders respectively.

[0007] The upper part of the column is slidably connected with a limiting sleeve, the limiting sleeve is located below the connecting slider, and the limiting sleeve can limit the connecting slider from moving downward; the supporting rod is connected to the limiting sleeve.

[0008] The support rod is provided with a plurality of limiting holes, and the limiting sleeve is connected with a limiting bolt through a threaded through hole, and the limiting bolt can extend into the limiting hole.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] like Figure 1-3 As shown, a portable small space tank jacking device includes a connecting component 1 and a column component 2. Two column components 2 are provided, and the two column components 2 are connected by the connecting component 1.

[0020] The column assembly 2 includes a jack 20, a column 21 and a support top plate 22. A support rod 23 is fixedly connected to the support top plate 22, and the support rod 23 is slidably connected to the column 21. The support top plate 22 is used to contact the object being lifted in order to increase the contact area.

[0021] A base 24 is fixed to the bottom of the column 21, a first connecting groove is provided on the top of the column 21, and a second connecting groove 26 opposite to the first connecting groove is provided on the bottom of the support top plate 22. The two ends of the jack 20 are respectively located in the first connecting groove and the second connecting groove 26.

[0022] When in use, pull the two column assemblies 2 to expand, so that the distance between the two column assemblies 2 is increased. Afterwards, select a suitable position to pad square wood on the ground of the tank body that needs to be jacked up to buffer the pressure and avoid damage to the ground.

[0023] The two unfolded column assemblies 2 are then placed on the side that requires jacking. A jack 20 of the required specifications is placed in the first connecting groove, with the plunger end of the jack 20 extending into the second connecting groove. When performing secondary grouting of the tank foundation, jacking is performed according to the designed grouting thickness. This involves operating the jack 20 to move its plunger upward, pushing the support top plate 22, and finally lifting the tank to a predetermined height. Secondary grouting is then performed.

[0024] After use, the jack 20 is operated to move its plunger downward, and then the jack 20 is removed. Finally, the two column assemblies 2 are pushed to move relative to each other, so that the distance between the two assemblies is shortened, thereby reducing the space occupied by the entire assembly and making it easier to carry.

[0025] Furthermore, a connecting slider 27 is slidably connected to the column 21. The connecting assembly 1 is preferably an X-shaped structure, which consists of two connecting rods 10 hinged in the middle, the lower ends of the two connecting rods 10 are respectively hinged to the corresponding columns 21, and the upper ends of the two connecting rods 10 are respectively hinged to the corresponding connecting sliders 27.

[0026] Furthermore, with the aforementioned X-shaped structure, after being lifted by the jack 20, to prevent the connecting slider 27 from moving downward due to prolonged reaction force (to prevent accidents), thereby increasing the distance between the two columns 21 and causing the tank body to move downward, a limit sleeve 28 is slidably connected to the column 21. The limit sleeve 28 is located below the connecting slider 27 and limits the downward movement of the connecting slider 27, preventing the distance between the two columns 21 from increasing and thus preventing accidents.

[0027] Specifically, the support rod 23 is connected to the limiting sleeve 28. Several limiting holes 29 are provided on the support rod 23. Limiting bolts 210 are connected to the limiting sleeves 28 via threaded through-holes. The limiting bolts 210 can extend into the limiting holes 29. Prior to jacking, the limiting sleeves 28 can be connected to the corresponding limiting holes 29 according to the jacking height. This ensures that after the jack 20 is raised to its highest point, the limiting sleeves 28 are driven by the support plate 22 through the support rod 23 to move below the connecting slider 27 (with contact or a small gap between them), thereby forming a stable structure. This prevents the two columns 21 from moving outward (increasing the distance between them) due to prolonged stress.

[0028] The specific adjustment method is to first loosen the limit bolt 210 to move it out of the limit hole 29, then push the limit sleeve 28 to move to the position to be adjusted, and then tighten the limit bolt 210, and the limit bolt 210 passes through the threaded through hole and extends into the corresponding limit hole 29.

[0029] Furthermore, the support top plate 22 is preferably fixedly connected to the support rod 23 by bolts; the support top plate 22 is provided with an arc-shaped support surface 220. That is, the support top plate 22 with arc-shaped support surfaces 220 of different sizes can be provided as needed, and can be replaced according to different specifications of tanks.

[0030] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
