Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction, in particular to an auxiliary device for hoisting a beam body with a steel wire rope. Background Art
[0002] In bridge construction, the beam is subject to heavy loads, high impact forces, high traffic density, and high standards for resistance to natural disasters, especially with certain vertical and lateral stiffness and dynamic performance requirements. The erection and hoisting of the beam is a key construction step, which specifically involves the safety hazards of large-scale mechanical operation, especially in the construction of adjacent railways and other operating lines. If a hoisting accident occurs, the consequences will be immeasurable.
[0003] In conventional beam hoisting operations, a beam hoist is used to hoist the beam onto a beam transport vehicle and transport it to the construction site. The T-beam on the beam transport vehicle is then hoisted onto a flatbed truck by an inverted gantry crane and transported to a bridge erecting machine. Finally, the bridge erecting machine is used to hoist the beam on the flatbed truck and erect it on the bridge pier. According to the above construction process, the beam needs to be hoisted at least three times (excluding the storage and hoisting of the beam during the prefabrication process), and due to different transportation and erection requirements for the beam, the hoisting point position is hoisted according to the distance specified in the design drawings.
[0004] Since the beam body needs to be hoisted multiple times using large machinery, and under the difficult conditions of construction near the operating line, ensuring the safety of the beam body hoisting operation is the primary control focus, and at the same time, the structural appearance quality of the beam body during the hoisting operation must also be ensured. The traditional operation method uses elastic rubber materials to fix the beam body at the hanging point, but through construction application, due to the heavy weight of the beam body and the slow hoisting operation, the elastic rubber material is tightened for a long time by the wire rope, which is easy to be damaged (cannot meet the construction requirements or needs to be replaced multiple times), resulting in concrete damage at the hanging point (needing secondary repair), and in severe cases, the wire rope is worn and slipped, resulting in safety accidents, causing casualties and property losses. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides an auxiliary device for hoisting a beam body with a steel wire rope.
[0006] The technical solution of the utility model is achieved in this way:

The bottom end of the lower plate body extends inwards and obliquely into the second rope groove, and the steel wire rope presses the bottom end of the lower plate body outwards so that the upper plate body presses the steel wire rope inwards.
[0010] Further, a through groove is formed on the surface of the first plate body. A support plate capable of moving downwards is arranged at the top of the first plate body. A lower pressing plate located in the second rope groove is arranged at the bottom end of the support plate, and the lower pressing plate is used for pressing down the part of the steel wire rope located in the second rope groove.
[0011] Further, the lower pressing plate has a "V" - shaped structure. When the upper plate body presses the steel wire rope, one side surface of the lower plate body is parallel to one side surface of the lower pressing plate.
[0012] Further, on one side surface of the two convex plates facing away from each other, a chute with a closed top end is provided. A slider is slidably arranged inside the chute, and the two sliders are respectively fixed to both sides of the support plate.

DETAILED DESCRIPTION
[0023] 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, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] refer to Figures 1 to 4 , an auxiliary device for lifting a beam body with a steel wire rope, comprising a first plate body 1 for supporting the side of the beam body, a second plate body 2 for supporting the bottom of the beam body, a first rope groove 3 arranged on the outer side of the first plate body 1, a second rope groove 4 arranged on the lower surface of the second plate body 2, and a locking plate 5 arranged in the first rope groove 3 for pressing the steel wire rope. In the process of lifting the beam body, the steel wire rope located on the side of the beam body is located in the first rope groove 3 of the auxiliary device, and the steel wire rope located at the bottom of the beam body is located in the second rope groove 4 of another auxiliary device, so as to prevent the steel wire rope from wearing against the beam body, and at the same time, it can prevent the steel wire rope from sliding, thereby improving the safety and stability of lifting, and the locking plate 5 is used to press the steel wire rope in the first rope groove 3, which can further prevent the steel wire rope from slipping out of the groove.
[0025] Among them, a convex plate 6 is provided between the outer side surface of the first plate body 1 and the lower surface of the second plate body 2, and two convex plates 6 are provided in the width direction, and the first rope groove 3 and the second rope groove 4 are formed between the two convex plates 6. Specifically, in this embodiment, the first plate body 1 and the second plate body 2 are integrally formed, and the convex plate 6 is a bent integral steel plate.
[0026] The locking plate 5 includes an upper plate body 5.1 and a lower plate body 5.2. The bottom end of the upper plate body 5.1 is rotatably arranged between two convex plates 6. The lower plate body 5.2 is fixedly arranged at the bottom end of the upper plate body 5.1. The included angle between the upper plate body 5.1 and the lower plate body 5.2 is an obtuse angle. The bottom end of the lower plate body 5.2 extends inwards and obliquely into the second rope groove 4, and the steel wire rope presses the upper plate body 5.1 to press the steel wire rope inwards by extruding the bottom end of the lower plate body 5.2 outwards.
[0027] After the steel wire rope passes through the first rope groove 3 and the second rope groove 4, the steel wire rope is extruded inwards by the lower plate body 5.2, so that the part of the steel wire rope between the first rope groove 3 and the second rope groove 4 is in a bent state. During the process of lifting the bridge, the steel wire rope will be tightened, and the steel wire rope exerts an outward pressure on the lower plate body 5.2 during the tightening process. The lower plate body 5.2 drives the upper plate body 5.1 to rotate inwards, so that the upper plate body 5.1 presses the steel wire rope in the first rope groove 3, realizing the locking function of the steel wire rope.
[0028] A through groove 7 is formed on the surface of the first plate body 1. A support plate 8 capable of moving downwards is arranged at the top of the first plate body 1. A lower pressing plate 9 located in the second rope groove 4 is arranged at the bottom end of the support plate 8. The lower pressing plate 9 is used to press down the part of the steel wire rope in the second rope groove 4.
[0029] During the process of lifting the beam body, the gravity of the beam body presses down the support plate 8, and the support plate 8 drives the lower pressing plate 9 to move downwards. At this time, the lower pressing plate 9 extrudes the steel wire rope towards one side of the lower plate body 5.2, so that the steel wire rope presses the lower plate body 5.2 more stably, thereby improving the pressing and locking effect of the upper plate body 5.1 on the steel wire rope.
[0030] The lower pressing plate 9 is in a "V" - shaped structure. When the upper plate body 5.1 presses the steel wire rope, one side surface of the lower plate body 5.2 is parallel to one side surface of the lower pressing plate 9. Specifically, after the beam body is lifted, the lower pressing plate 9 cooperates with the lower plate body 5.2 to lock the part of the steel wire rope between the first rope groove 3 and the second rope groove 4, further improving the stability and safety of the hoisting.
[0031] On the opposite side surfaces of the two convex plates 6, there are chutes 10 with closed tops. Sliders 11 are slidably arranged inside the chutes 10. The two sliders 11 are respectively fixed to both sides of the support plate 8. Through the cooperation of the sliders 11 and the chutes 10, the support plate 8 is stably installed on the first plate body 1, and the top of the chute 10 is in a closed state, which can prevent the support plate 8 from separating from the first plate body 1. The support plate 8 is in a "C" - shaped structure with an open bottom, and the two sliders 11 are respectively fixedly arranged on the inner wall surfaces of both sides of the support plate 8.
[0032] The convex plate 6 is provided with a first through hole 12, the upper plate body 5.1 is provided with a second through hole 13, screw rods 14 are passed through the first through hole 12 and the second through hole 13, and locking nuts 15 threadedly sleeved on the screw rods 14 are provided on opposite sides of the two convex plates 6.
[0033] By such arrangement, after the locking nut 15 is removed, the screw rod 14 is pulled out to remove the locking plate 5. After the locking plate 5 is removed, it is more convenient to put the steel wire rope into the first rope groove 3 and the second rope groove 4. After the steel wire rope passes through the first rope groove 3 and the second rope groove 4, the locking plate 5 is reinstalled.
[0034] In the actual hoisting process, there are multiple steel wire ropes for hoisting corresponding to the length direction of the beam body, and the auxiliary device is used between each steel wire rope and the beam body. Specifically, two adjacent auxiliary devices located at the same height are connected by a screw rod 14. At this time, the screw rod 14 connects the two auxiliary devices into one. In the actual application process, the distance between the steel wire ropes at both ends of the screw rod 14 can be adjusted by rotating the locking nut 15.
[0035] Furthermore, during the actual lifting process, the steel wire rope is distributed in an inverted "V" shape on the side of the beam body, and the device on the two parts corresponding to the same height of the steel wire rope is fixed by a screw rod 14, making it more difficult for the steel wire rope to slide on the auxiliary device, further improving the lifting stability and safety.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
