Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and in particular to a horizontal correction component and method for a tilting beam used in hoisting large tank equipment. Background Technology

[0002] The tail-turning frame is a mechanical product used for the tail-turning of large towers, reactors and other chemical equipment. Its structure is mainly composed of a turning beam, sliding fulcrum, hinge support, and load-sharing track plate. Its basic working principle is to use two turning fulcrums (main and auxiliary hinge fulcrums) to turn the equipment on the hinge support, thereby enabling the equipment to complete the lifting process from a horizontal to a vertical state.

[0003] In the existing technology, the placement of the main support and the auxiliary support is generally done by manually marking the position and using an auxiliary crane to place the main support and the auxiliary support at the specified distance. However, due to errors in the marking and placement operation, a distance error occurs between the main hinge point and the auxiliary hinge point. This distance error has a significant impact on the stress state of the auxiliary tilting pin and affects the normal use of the tail tilting frame. Summary of the Invention

[0004] The purpose of this invention is to provide a horizontal correction component and method for lifting and tilting beams of large tank equipment, so as to solve the problems existing in the prior art.

[0006] A tilting beam; the tilting beam is used to be fixedly connected to the bottom surface of the skirt base of the equipment to be hoisted, and a sliding fulcrum is detachably connected to the tilting beam;

[0007] A flip pin; the flip pin is divided into a main flip pin and a secondary flip pin. The main flip pin is fixedly installed at one end of the flip beam, and the secondary flip pin is fixedly installed on the sliding fulcrum. The main flip pin and the secondary flip pin have the same structure.

[0008] Main support; the main support is used to cooperate with the main tilting pin on the tilting beam to form a main tilting fulcrum;

[0009] The main support is equipped with a secondary support; the secondary support is used to cooperate with the secondary flip pin on the sliding fulcrum to form a secondary flip fulcrum; the height of the main support is lower than the height of the secondary support.

[0010] Preferably, the flip pin includes a hinge shaft, on which a trapezoidal limiting member is rotatably connected. Both the main support and the secondary support are provided with trapezoidal limiting grooves, and the trapezoidal limiting member is adapted to the trapezoidal limiting groove.

[0011] Preferably, the trapezoidal limiting member includes trapezoidal blocks at both ends of the hinge shaft, the trapezoidal blocks being adapted to the trapezoidal limiting groove; a through hole is provided at the upper end of the trapezoidal block, a lubricating element is fixedly connected in the through hole, and the trapezoidal block is rotatably connected to the hinge shaft through the lubricating element.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This invention provides a horizontal correction component for a lifting and tilting beam of a large tank equipment, comprising:

[0031] Tilting beam 1; Tilting beam 1 is used to be fixedly connected to the bottom surface of the skirt base of the equipment to be hoisted, and sliding support point 2 is detachably connected to tilting beam 1;

[0032] Flip pin; The flip pin is divided into a main flip pin and a secondary flip pin. The main flip pin is fixedly installed at one end of the flip beam 1, and the secondary flip pin is fixedly installed on the sliding support 2. The main flip pin and the secondary flip pin have the same structure.

[0033] Main support 3; Main support 3 is used to cooperate with the main tilting pin on the tilting beam 1 to form the main tilting fulcrum;

[0034] And secondary support 4; secondary support 4 is used to cooperate with the secondary flip pin on the sliding fulcrum 2 to form a secondary flip fulcrum; the height of the main support 3 is lower than the height of the secondary support 4.

[0035] Furthermore, the flip pin includes a hinge shaft 5, on which a trapezoidal limiting member is rotatably connected. Both the main support 3 and the secondary support 4 are provided with trapezoidal limiting grooves 6, and the trapezoidal limiting member is adapted to the trapezoidal limiting groove 6. The trapezoidal limiting member includes trapezoidal blocks 7 at both ends of the hinge shaft 5. The trapezoidal blocks 7 are isosceles trapezoidal structures and are adapted to the trapezoidal limiting grooves 6. A through hole is opened at the upper end of the trapezoidal block 7, and a self-lubricating bushing 8 is fixedly connected in the through hole. The trapezoidal block 7 is rotatably connected to the hinge shaft 5 through the self-lubricating bushing 8. To ensure the stability of the connection between the flip pin and the flip beam 1, end caps 9 are provided at both ends of the hinge shaft 5, and the end caps 9 are detachably connected to the hinge shaft 5.

[0036] Furthermore, to facilitate fixing the hinge support and distribute the pressure from the hinge support, hinge support fixing plates 10 are fixedly connected to the bottom ends of the main support 3 and the auxiliary support 4; to further distribute the pressure from the hinge support, a load-sharing base plate is fixedly installed at the bottom end of the hinge support fixing plate 10.

[0037] Furthermore, to facilitate the connection and fixation of the tilting beam 1 with the hoisting equipment, a lock and connector are installed on the tilting beam 1, and the tilting beam 1 is fixedly connected to the skirt of the equipment to be hoisted through the lock and connector.

[0038] A method for hoisting and adjusting the horizontal alignment of a tilting beam using large tank equipment specifically includes the following steps:

[0039] Step 1: Move the equipment carrying the horizontal correction component of the hoisting tilting beam to the side of the equipment to be hoisted. According to the outer diameter of the skirt of the equipment to be hoisted, adjust the position of the sliding support 2 on the tilting beam 1, and adjust the distance between the main support 3 and the secondary support 4.

[0041] Step 3: Use the lifting device to lift the equipment to be lifted, so that the equipment to be lifted is flipped from a horizontal position to an upright position.

[0042] During the lifting process, the equipment to be lifted is first rotated horizontally around the main rotating pin, with the tilt angle of the equipment rotating from 0° to θ. 变The lifting continues until the secondary tilting pin on sliding fulcrum 2 contacts and limits the movement of the secondary support 4. During this process, under the weight of the trapezoidal block 7, the trapezoidal block 7 rotates with the self-lubricating bushing 8, ensuring that the trapezoidal block 7 is always oriented downwards and automatically aligned with the limiting groove of the secondary support 4. The inclined surface of the trapezoidal block 7 contacts the inclined surface of the limiting groove. By relying on the pressure of the load and the correction of the inclined surface, the distance error between the main hinge fulcrum and the secondary hinge fulcrum caused by the positioning and marking errors, placement operation errors, and overall deformation of the tilting beam 1 is eliminated, thus realizing the horizontal eccentricity correction function of the tilting beam 1. The lifting of the equipment to be lifted continues, and the equipment to be lifted rotates around the secondary support 4 as the center until the tilt angle of the equipment to be lifted changes from θ. 变 Flip it to 90°.
