Description

Technical Field

[0001] The utility model relates to the technical field of steel column positioning, in particular to an anti-offset positioning device for steel column assembly. Background Art

[0002] A steel column is a column made of steel. Most columns in large and medium-sized industrial factories, large-span public buildings, high-rise buildings, light movable houses, working platforms, trestles and brackets, etc. are made of steel columns. Generally, steel columns are used as support structures, so positioning brackets for steel column assembly are manufactured.

[0003] The verticality accuracy requirement of the steel column is relatively high. However, during the construction process, due to the influence of various factors, such as the verticality deviation of the bored cast-in-place pile hole wall, the straightness of the steel pipe column itself, etc., it may be difficult for the steel column to meet the design requirements during the lowering and plumb adjustment process; the impact force generated during concrete pouring may cause the steel column to displace; the unevenness of the backfill soil may exert lateral pressure on the steel column, affecting its verticality; improper operation during the removal of the steel casing may collide with the steel column, resulting in damage to the verticality and deviation. Although the anti-offset positioning devices in the prior art can prevent the pile driving from tilting, they cannot ensure the verticality of the steel column, and the tilting situation will still occur, resulting in the instability of the later building and potential safety hazards. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an anti-offset positioning device for steel column assembly.

[0005] The technical solution of the utility model is: an anti-offset positioning device for steel column assembly, including an installation frame, and positioning components respectively arranged at the four corners of the top and the four corners of the bottom of the installation frame; the positioning component includes slide rails arranged at the four corners of the top and the four corners of the bottom of the installation frame, an L-shaped positioning cavity and an arc-shaped positioning cavity fixedly connected up and down by a shaft rod, the lower end of the shaft rod is provided with a slider slidably connected with the slide rail, a cavity is arranged in the slider, and a cam is arranged on the shaft rod and rotatably connected with the cavity, a liquid bag column squeezed by the rotation of the cam is arranged in the cavity, and the liquid bag column is communicated with liquid outlet holes arranged on the sides of the L-shaped positioning cavity and the arc-shaped positioning cavity through a first pipeline.

[0006] Furthermore, a liquid storage tank is arranged on the installation frame, the liquid storage tank is connected with the liquid bag column through a second pipeline, one-way valves are arranged in both the second pipeline and the first pipeline, and a spring is arranged in the liquid bag column;

[0007] Description: In view of the problem that during the positioning process of the steel column, the positioning part and the steel column are prone to high-strength friction, which weakens the service life of the equipment. With the above settings, the liquid bag column can be replenished with liquid, and when the positioning part is rotated and selected, the contact surface between the positioning part and the steel column can be lubricated with liquid, optimizing the repeated lubrication effect of the equipment. The spring can automatically reset after positioning, and at the same time, it can effectively replenish the liquid bag column to prepare for efficient liquid discharge next time, further reducing the friction between the positioning part and the steel column and improving the service life of the equipment.

[0008] Further, sponge pads are provided on the sides of the L-shaped positioning cavity and the arc-shaped positioning cavity;

[0009] Description: The sponge pads can make the liquid fully immersed inside, so as to achieve a better clamping effect on the steel column while avoiding wear on the equipment itself and improving the anti-wear effect.

[0010] Further, pipelines are provided in the L-shaped positioning cavity and the arc-shaped positioning cavity. The outlet of the pipeline is connected to the liquid outlet hole, and the inlet of the pipeline is connected to the first pipeline;

[0011] Description: The above settings can enable efficient liquid transfer, thereby improving the lubrication efficiency.

[0012] Furthermore, the liquid in the liquid bag column is anti-wear hydraulic oil; specifically, commercially available LH-M46 anti-wear hydraulic oil is used;

[0013] Description: The above anti-wear hydraulic oil has good anti-wear properties to ensure normal lubrication of the steel column and the positioning part under high-pressure and high-speed harsh conditions and reduce wear.

[0014] Compared with the existing column anti-offset device, the beneficial effects of the present utility model are:

[0015] (1) The present utility model provides a steel column anti-offset positioning device that can adapt to different forms, which can effectively position steel columns of different sizes by using the slide rail, preventing position deviation during the assembly process, thereby weakening the positioning effect.

[0023] To further elaborate on the methods and achieved effects of the present invention, the technical solutions of the present invention will be clearly and completely described below in combination with experiments.

[0024] Embodiment 1: As Figures 1 - 2 shown, a deviation-preventing positioning device for steel column assembly includes a mounting frame 1 and positioning components 2 respectively arranged at the four corners of the top and bottom of the mounting frame 1; the positioning component 2 includes slide rails 21 arranged at the four corners of the top and bottom of the mounting frame 1, an L-shaped positioning cavity 23 and an arc-shaped positioning cavity 24 fixedly connected up and down through a shaft rod 22. The lower end of the shaft rod 22 has a slider 211 slidably connected to the slide rail 21. A cavity is provided inside the slider 211. A cam 221 is provided on the shaft rod 22 and is rotatably connected to the cavity. A liquid sac column 25 squeezed by the rotation of the cam 221 is provided inside the cavity. The liquid sac column 25 is communicated with liquid outlet holes provided on the sides of the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24 in contact with the steel column through a first pipeline; a knob is provided at the top of the shaft rod 22; it can be understood that the cam 221 is eccentrically and fixedly connected to the shaft rod 22, and one end of the liquid sac column 25 is slidably connected to the side surface of the cam 221;

[0025] The L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24 are arranged in the opposite direction and need to meet the requirement that during the process of clamping the steel column in one cavity, it is not affected by the position of the other cavity; in this embodiment, the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24 are symmetrically arranged with the center of the shaft rod 22,

[0026] The working principle of this embodiment is as follows: First, select the type of steel column. Then, adjust the shaft rod 22 through the knob to turn the positioning cavity of the corresponding steel column to the corresponding orientation. Then, drive the slider 211 according to the size of the steel column so that the slider 211 slides inside the slide rail 21 to effectively clamp the steel column, thereby achieving the effect of positioning and preventing deviation. When the shaft rod 22 rotates, under the action of the cam 221 squeezing the liquid sac column 25, the lubricating liquid inside the liquid sac column 25 is transferred to the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24, and then the sides of the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24 in contact with the steel column are lubricated to play a role in preventing wear.

[0027] Embodiment 2: Different from Embodiment 1, as Figures 3 - 4 shown, a liquid storage tank 26 is provided on the mounting frame 1. The liquid storage tank 26 is connected to the liquid sac column 25 through a second pipeline, and one-way valves are provided in both the second pipeline and the first pipeline. A spring is provided inside the liquid sac column 25; it should be noted that the direction of the one-way valve in the second pipeline only allows the liquid in the liquid storage tank 26 to enter the liquid sac column 25, and the direction of the one-way valve provided in the first pipeline is only to allow the liquid in the liquid sac column 25 to flow into the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24;

[0028] The liquid in the liquid sac column 25 is lubricating liquid, specifically using commercially available LH-M46 anti-wear hydraulic oil;

[0029] The difference in the working principle of this embodiment from that of Embodiment 1 is that after the positioning work is completed, the one-way valve of the second pipeline is opened. Under the action of the spring, the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24 are reset, and at the same time, the liquid sac column 25 expands and resets, and the lubricating liquid is extracted from the liquid storage tank 26 into the liquid sac column 25 for lubricating the sides of the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24 in contact with the steel column before the next use.

[0030] Embodiment 3: Different from Embodiment 2, as Figure 5 shown, sponge pads 230 are provided on the sides of the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24;

[0031] The difference in the working principle of this embodiment from that of Embodiment 2 is that the liquid wets the sponge pads 230, and the lubricating liquid realizes positioning and clamping with the steel column through the sponge pads 230, which can further reduce the wear effect on itself during the clamping process of the equipment and improve the service life of the equipment.

[0032] Embodiment 4: Different from Embodiment 2, not shown in the figure, pipelines are provided in the L-shaped positioning cavity 23 and the arc-shaped positioning cavity 24. The outlet of the pipeline is connected to the liquid outlet hole, and the inlet of the pipeline is connected to the first pipeline;

[0033] The working principle of this embodiment is different from that of Embodiment 2 in that the above settings can ensure the effective circulation of the lubricating fluid, thereby optimizing the anti-wear efficiency.
