Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a tank hoisting positioning device. Background Art

[0002] The tanks used on construction sites to store water for construction, production and life of workers generally use steel plates with a thickness of no more than 6 mm as the tank walls. The design pressure of the tank is less than 0.1 MPa, which means it can withstand a water column pressure of no more than 10 meters. The outer dimensions of the tank are 3.8 meters (diameter) × 3.8 meters (height).

[0003] It is difficult to control the size of the tank body during the production process, especially for cylindrical tank bodies. Size errors are prone to occur during the production process, and the higher the height of the tank body, the greater the cumulative error. When welding the tank body wall within 6 mm, deformation is prone to occur, resulting in the inability to align the seams.

[0004] In order to solve the above problem, a method is disclosed in the patent document with publication number “ ”.

[0005] In the above-mentioned prior art, although the outer diameter of the tank is positioned, the clamping claws of the lifting device cannot be accurately positioned at the center of the tank body during the lifting process. Therefore, the tank body is prone to displacement when the lifting device is clamped, and the tank body is prone to tilt when lifting and lowering. The tank body is also prone to damage during the lifting process. Therefore, a tank body lifting and positioning device is needed. Utility Model Content

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.

[0024] Example: Reference Figure 1-3 A tank body hoisting and positioning device shown in the figure comprises a hoisting frame 1 and a movable hoisting arm 2 slidably mounted on the front end of the hoisting frame 1, the supporting column of the hoisting frame 1 is a column that can be raised and lowered, a hoisting claw 3 is fixed at the lower end of the movable hoisting arm 2, a mounting column 4 is fixed at the lower end of the cross arm of the hoisting frame 1, a positioning ring 5 is slidably mounted on the lower end of the mounting column 4 through a movable connecting piece, and the positioning ring 5 is coaxially arranged with the hoisting claw 3;

[0025] One side of the positioning ring 5 is transmission-connected to the movable boom 2 through a linkage;

[0026] A positioning block 6 for guiding the tank body is also installed in the positioning ring 5 .

[0027] Based on the above structure, when the tank body lifting and positioning device is used to lift the tank body, firstly, the horizontal arm of the lifting frame 1 is rotated, and the movable lifting arm 2 is driven to move to the top of the tank body. At this time, it is only necessary to adjust the height of the movable lifting arm 2 so that the positioning ring 5 can be arranged around the surrounding side of the tank body to be lifted, and the positioning block 6 can be used to position the tank body. The central axis of the tank body is adjusted to the same position as the central axis of the positioning ring 5, so that the central axis of the tank body can be coaxial with the lifting claw 3, which is convenient for the lifting claw 3 to stably clamp the tank body, avoid the deviation or tilt caused by the inconsistency of the central axis of the tank body and the lifting claw 3 during the lifting process, and ensure that the tank body is not easily damaged during lifting and lowering.

[0028] Further, the movable connecting member includes a telescopic support rod 9, a fixed rod of the telescopic support rod 9 is fixed to the mounting column 4, a movable rod of the telescopic support rod 9 is slidably inserted into the fixed rod of the telescopic support rod 9, and one end is fixed to one side of the positioning ring 5;

[0029] The linkage member comprises a linkage plate 10 , and the upper and lower ends of the linkage plate 10 are respectively fixed to the lower end of the movable boom 2 and the upper end of the movable rod of the telescopic support rod 9 .

[0030] By setting the telescopic support rod 9 and the linkage plate 10, when the tank body is heavy and difficult to move, the positioning ring 5 can produce an offset that adapts to the tank body under the guiding action of the positioning block 6, so that the positioning ring 5 moves to a position coaxial with the tank body. At this time, the positioning ring 5 drives the movable boom 2 to slide synchronously in the same direction through the movable rod of the telescopic support rod 9 and the linkage plate 10, so that the lifting claw 3 on the movable boom 2 can also automatically move to a position coaxial with the tank body, which is conducive to achieving the purpose of adjusting the tank body and the lifting claw 3 to be coaxial when lifting the tank body, and ensuring that the tank body will not be tilted or damaged during the subsequent lifting process.

[0031] Furthermore, a movable rod 7 is slidably penetrated through the side wall of the positioning ring 5, and one end of the movable rod 7 is fixed to the side wall of the positioning block 6 close to the positioning ring 5; a tension spring 8 is sleeved on the end of the movable rod 7 away from the positioning block 6, and the two ends of the tension spring 8 are respectively fixed to one end of the movable rod 7 and the outer wall of the positioning ring 5;

[0032] The positioning block 6 is a fan-shaped block. The upper and lower ends of the positioning block 6 are both provided with arc-shaped guiding inclined surfaces 11 . The guiding inclined surfaces 11 are inclined and expanded outwardly toward the upper end or the lower end of the positioning block 6 .

[0033] By setting the movable rod 7, the tension spring 8 and the guiding inclined surface 11, the upper and lower ends of the positioning block 6 can be made to contact the tank body (that is, when the tank body is lowered or lifted, the tank body first contacts the upper end surface or the lower end surface of the positioning block 6). The upper end or the lower end of the tank body first contacts the guiding inclined surface 11, and automatically moves to the center position of the plurality of positioning blocks 6 under the guidance of the guiding inclined surface 11, so that the tank body and the positioning ring 5 can be made coaxial, and the plurality of positioning blocks 6 are respectively located on the peripheral side of the tank body. The tank body can also be temporarily auxiliary clamped under the elastic force of the tension spring 8, so as to avoid unnecessary movement of the tank body when it contacts the lifting claw 3 or separates from the lifting claw 3, causing the tank body to tilt again, and the use effect is better.

[0034] Working principle of the utility model: in daily use, first rotate the horizontal arm of the hoisting frame 1, and drive the movable hoisting arm 2 to move above the tank body. At this time, it is only necessary to adjust the height of the movable hoisting arm 2, so that the positioning ring 5 can be arranged around the surrounding side of the tank body to be hoisted, and the positioning block 6 can position the tank body, and adjust the central axis of the tank body to the same position as the central axis of the positioning ring 5, so that the central axis of the tank body and the lifting claw 3 can be coaxial, which is convenient for the lifting claw 3 to stably clamp the tank body, avoid the deviation or tilt caused by the inconsistency of the central axis of the tank body and the lifting claw 3 during the hoisting process, and ensure that the tank body is not easily damaged when hoisting and lowering; When the tank body is heavy and difficult to move, the positioning ring 5 can produce an offset adapted to the tank body under the guiding action of the positioning block 6 through the arrangement of the telescopic support rod 9 and the linkage plate 10, so that the positioning ring 5 moves to a position coaxial with the tank body. At this time, the positioning ring 5 drives the movable boom 2 to slide synchronously in the same direction through the movable rod of the telescopic support rod 9 and the linkage plate 10, so that the lifting claw 3 on the movable boom 2 can also automatically move to a position coaxial with the tank body, which is conducive to achieving the purpose of adjusting the tank body and the lifting claw 3 to be coaxial when lifting the tank body, and ensuring that the tank body will not be tilted or damaged during the subsequent lifting process.
