Description

Technical Field

[0001] The utility model relates to the technical field of jacking machines, and more specifically to a jacking machine with multiple combined height tower bodies. Background Art

[0002] At present, tower cranes are widely used in various engineering constructions due to their high lifting height and large working range. In some engineering projects, due to the structural limitations of the construction building, it is impossible to attach, which requires the tower crane to have a high free height. In order to save engineering costs, a variable-section tower body is usually used to increase the free height, that is, a large-section standard section is used at the bottom of the tower body, and a small-section standard section is used at the top.

[0003] The existing jacking operation can only be carried out using a jacking frame matched with a small-section standard section, which causes the problem that the initial installation height of the tower crane is too high, and greatly increases the cost in terms of auxiliary cranes and the like.

[0004] After searching, the Chinese patent with publication number CN218371406U discloses a telescopic adjustable variable-section lifting frame. For tower cranes with ultra-high free height, this utility model can save the cost of tower crane installation and disassembly, improve the installation and disassembly efficiency, and maximize the benefits of tower crane users; it has strong versatility, and tower cranes with different tower bodies can share the same lifting frame, saving the cost of purchasing the machine.

[0005] However, when the above-mentioned jacking machine is actually used, different requirements are placed on the combination of the tower body according to the actual situation. The height of most tower bodies is relatively fixed, and the height adjustment of the tower body may not be accurate enough, thus affecting the subsequent use of the jacking machine.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The embodiment of the present application discloses a multi-combination height tower body of a jacking machine, specifically comprising a standard section 1, a second adjustment section 2 is movably connected to the top of the standard section 1, and a first adjustment section 3 is movably connected to the top of the second adjustment section 2.

[0038] Reference Figure 2As shown, specifically, the height of the standard section 1 is set to 600mm, the standard section 1 is made of steel, and the top of the standard section 1 is fixedly connected with multiple locating pins. The number of locating pins is four, and the bottom ends of the four locating pins are welded and fixed to the top of the standard section 1. A forklift hole is set on the outside of the standard section 1 to facilitate the movement and lifting of the standard section 1, wherein the cross-sections of the standard section 1, the second adjustment section 2, and the first adjustment section 3 are square.

[0039] Reference Figure 3 As shown, specifically, the height of the second adjustment section 2 is set to 200 mm, the second adjustment section 2 is made of steel, and the top of the second adjustment section 2 is fixedly connected with multiple positioning pins. The number of positioning pins is four, and the bottom ends of the four positioning pins are welded and fixed to the top of the second adjustment section 2. The height of the tower body is adjusted according to the on-site conditions.

[0040] Reference Figure 4 As shown, specifically, the height of the first adjustment section 3 is set to 100 mm, the first adjustment section 3 is made of steel, and a plurality of positioning pins are fixedly connected to the top of the first adjustment section 3. The number of the positioning pins is four, and the bottom ends of the four positioning pins are welded and fixed to the top of the first adjustment section 3, so as to facilitate accurate control of the height of the tower body.

[0041] The working principle of the utility model is as follows: when lifting or leveling heavy structures and buildings, the jacking cylinder is started to jack up the top frame, and the auxiliary hoisting hoists the standard section 1 from the ground to the introduction system bracket. The introduction trolley receives the command and automatically lifts, jacks up the standard section 1 and transports it to the base and then slowly descends. After the standard section falls steadily to the base leg pin, the trolley returns to wait for the next command; then the jacking cylinder descends, and the top section slowly descends to the standard section leg to complete the connection, and multiple standard sections are introduced repeatedly to the required height. When it is necessary to adjust the height of the standard section below 600mm, the second adjustment section 2 can be lifted by the auxiliary hoist through the four lifting ears on the top, and then placed on the introduction trolley, so that the tower body can be adjusted according to the height of the second adjustment section 2, and the first adjustment section 3 can be lifted through the four lifting holes on the top at the same time. For different height adjustments of the tower body, the number of standard sections 1, second adjustment sections 2 and first adjustment sections 3 can be freely combined according to the required jacking height.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
