Description

Technical Field

[0001] The utility model relates to the technical field of power supply and distribution protection for electrical equipment, in particular to an auxiliary structure for installing an extra-long bridge. Background Art

[0002] Cable trays are commonly used supporting and protecting devices for laying cables in the power supply system of electrical equipment. They protect and guide the cables laid in the cable trays. Traditional cable trays are mainly divided into trough-type, ladder-type, tray-type and grid-type structures. Cable trays are widely used in production and life. For some factory garages and other places, it is often necessary to install extra-long cable trays. According to the conventional method, they are installed section by section. Workers need to constantly move the ladder to hoist each section of the cable tray. The manpower burden is heavy and the installation efficiency is low. Therefore, it is necessary to provide an auxiliary structure that can easily and quickly install extra-long cable trays. Utility Model Content

[0003] The utility model aims to provide an auxiliary structure for installing an extra-long bridge, so as to provide an auxiliary structure capable of conveniently and quickly installing the extra-long bridge.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an auxiliary structure for installing an extra-long bridge, comprising at least two groups of frame parts and angle steels, the length of the angle steels being greater than the length of a single bridge, the cross-section of the angle steels being L-shaped, the bending parts of the two angle steels respectively supporting the two bottom corners of the bridge, the frame part being sleeved on the outer periphery of the angle steels and the bridge, and a hanging ring being provided above the frame part.

[0005] The beneficial effects of this program are:

[0006] Through the above-mentioned settings, the bridge can be pre-assembled on the ground. After laying two angle steels, the bridge is placed on top of the angle steels. The angle steels support the bridge. After laying, the frame is placed on the outer periphery of the angle steels and the bridge, and then a fixed pulley or electric hoist is used for hoisting and installation. The ground assembly and overall lifting method can save workers' time and energy, avoid the tedious operations in the hoisting process during high-altitude operations, thereby significantly improving construction efficiency and shortening construction period. At the same time, angle steels are set for support and pre-assembly. The two angle steels can limit the bridge assembly, ensure that multiple bridges are located in the same horizontal plane and verticality, increase the overall strength of the bridge, improve the hoisting stability, and ensure that the bridge does not deform during the hoisting process.

[0007] Through ground assembly and overall lifting, the time and frequency of workers' work at height are reduced, thereby reducing their labor intensity. Operators can better control the connection quality of each bridge. At the same time, the auxiliary structure during the overall lifting process can ensure the stability and verticality of the bridge, thereby ensuring the installation quality and reducing the physical discomfort and safety risks that may be caused by operators working at height for a long time.

[0008] Preferably, as an improvement, the frame body includes a U-shaped frame and a locking piece, the ends of the U-shaped frame are hinged with connecting plates, the two connecting plates are fixed by the locking piece, and the two side walls of the U-shaped frame are detachably connected to the angle steels on both sides by bolts.

[0009] The beneficial effects are: the connecting plate is fixed by a locking piece, which is convenient for subsequent lifting through a lifting ring. The two side walls of the U-shaped frame are detachably connected to the angle steels on both sides by bolts, which enhances the overall stability and reliability and effectively prevents the frame components from loosening or dislocation during installation.

[0010] Preferably, as an improvement, a plurality of limiting structures are detachably connected between the two angle steels, the limiting structures comprising a bottom plate, a protrusion being provided on the bottom plate, both ends of the protrusion being abutted against the angle steel, both ends of the bottom plate being provided with connecting parts detachably connected to the angle steel, the connecting parts comprising a rotating shaft and a strip block rotatably arranged on the rotating shaft, a plurality of strip through holes are arrayed on the angle steel for the strip blocks to pass through, and recessed grooves which can be engaged with the strip blocks are provided around the strip through holes.

[0011] The beneficial effects are: by setting a limiting mechanism between the two angle steels, multiple connection points can be formed between the two angle steels. On the one hand, the connection between the two angle steels can be strengthened, and on the other hand, the two angle steels can be kept parallel, which is beneficial to the placement of the bridge frame and can accurately limit the bridge frame. The angle steels on both sides are limited by the protrusions. When in use, the angle steels are placed against both sides of the protrusions, and the strip blocks on both sides of the bottom plate are passed through the strip through holes and the strip blocks are rotated to engage with the sink grooves. By setting the sink grooves, the strip blocks can be prevented from protruding from the surface of the angle steels, making the placement of the bridge frame more flat.

[0012] Preferably, as an improvement, a rubber pad is provided between the angle steel and the U-shaped frame.

[0013] The beneficial effects are: the rubber pad has good elasticity and shock absorption performance, which can play a buffering role during the installation process, reduce the impact of shock and vibration on the bridge structure, and thus protect the bridge components from damage; during the installation process, due to the unevenness of the ground or uneven loading of the lifting equipment, it may cause uneven stress between the angle steel and the U-shaped frame. The rubber pad can withstand and disperse these uneven loads to protect the stability and integrity of the bridge structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example

[0021] The embodiment is basically as follows Figure 1-Figure 4 As shown, Figure 1 and Figure 2 An auxiliary structure for installing an extra-long bridge 12 is shown, comprising at least two groups of frame parts and angle steels 1. The length of the angle steels 1 is greater than the length of a single bridge 12. The cross-section of the angle steels 1 is L-shaped. The bending parts of the two angle steels 1 support the two bottom corners of the bridge 12 respectively. The frame parts are sleeved on the outer periphery of the angle steels 1 and the bridge 12. A rubber pad 13 is provided between the angle steels 1 and the U-shaped frame 3. During the installation process, due to the unevenness or uneven loading of the ground or lifting equipment, uneven stress between the angle steels 1 and the U-shaped frame 3 may occur. The rubber pad 13 can withstand and disperse the uneven load to protect the stability and integrity of the bridge 12 structure.

[0022] like Figure 2 and Figure 4 As shown, in this embodiment, the frame portion includes a U-shaped frame 3 and a locking piece, the ends of the U-shaped frame 3 are hinged with connecting plates 4, the lifting ring 2 is welded and fixed to one of the connecting plates 4, the U-shaped frame 3 is sleeved on the outside of the rubber sleeve, the two connecting plates 4 are fixed by the locking piece, and the two side walls of the U-shaped frame 3 are detachably connected to the angle steels 1 on both sides by bolts 5; the connecting plate 4 is fixed by the locking piece, which is convenient for subsequent lifting through the lifting ring 2, and the two side walls of the U-shaped frame 3 are detachably connected to the angle steels 1 on both sides by bolts 5, which enhances the overall stability and reliability and effectively prevents the frame components from loosening or dislocation during installation.

[0023] like Figure 3As shown, in this embodiment, a plurality of limiting structures are detachably connected between the two angle steels 1, and the limiting structure includes a bottom plate 6, a convex block 7 is provided on the bottom plate 6, and both ends of the convex block 7 are against the angle steel 1, and both ends of the bottom plate 6 are provided with a connecting part detachably connected to the angle steel 1, and the connecting part includes a rotating shaft 8 and a strip block 9 rotatably arranged on the rotating shaft 8, and a plurality of strip through holes 10 for the strip block 9 to pass through are arranged on the angle steel 1, and a sink groove 11 that can be clamped with the strip block 9 is opened around the strip through hole 10, and a limiting mechanism is provided between the two angle steels 1, so that the two angle steels 1 can be connected. A plurality of connection points are formed between the two angle steels 1, which can strengthen the connection between the two angle steels 1 on the one hand, and can keep the two angle steels 1 parallel on the other hand, which is beneficial to the placement of the bridge frame 12 and can accurately limit the position of the bridge frame 12. The angle steels 1 on both sides are limited by the protrusions 7. When in use, the angle steels 1 are placed against the two sides of the protrusions 7, the strip blocks 9 on both sides of the bottom plate 6 are passed through the strip through holes 10 and the strip blocks 9 are rotated to engage with the sink grooves 11. By setting the sink grooves 11, the strip blocks 9 do not protrude from the surface of the angle steels 1, so that the placement of the bridge frame 12 is smoother.

[0024] The specific implementation process is as follows:

[0025] Through the above-mentioned arrangement, the bridge frame 12 can be pre-assembled on the ground. After laying two angle steels 1, the bridge frame 12 is placed above the angle steels 1, and the angle steels 1 support the bridge frame 12. After laying, the frame part is sleeved on the periphery of the angle steels 1 and the bridge frame 12, and then hoisted using a fixed pulley or an electric hoist. The angle steels 1 on both sides are limited by the protrusions 7. When in use, the angle steels 1 are pressed against both sides of the protrusions 7, and the strip blocks 9 on both sides of the bottom plate 6 are passed through the strip through holes 10 and the strip blocks 9 are rotated to engage with the sink grooves 11. By setting the sink grooves 11, the strip blocks 9 can be prevented from protruding from the surface of the angle steels 1, so that the placement of the bridge frame 12 is more flat.

[0026] The method of ground assembly and overall lifting can save workers' time and energy and avoid tedious operations during the hoisting process in high-altitude operations, thereby significantly improving construction efficiency and shortening construction period. At the same time, angle steels 1 are set for support and pre-assembly. The two angle steels 1 can limit the bridge frame 12 components to ensure that multiple bridge frames 12 are located in the same horizontal plane and verticality, increase the overall strength of the bridge frame 12, improve the hoisting stability, and ensure that the bridge frame 12 does not deform during the hoisting process.

[0027] Through ground assembly and overall lifting, the time and frequency that workers need to work at heights are reduced, thereby reducing their labor intensity. Operators can better control the connection quality of each bridge 12. At the same time, the auxiliary structure during the overall lifting process can ensure the stability and verticality of the bridge 12, thereby ensuring the installation quality and reducing the physical discomfort and safety risks that may be caused by operators working at heights for a long time.
