Description

Technical Field

[0001] The utility model belongs to the technical field related to bridge frames, and in particular relates to a connection component of a large-span combined bridge frame. Background Art

[0002] Cable bridges for large spans can be categorized as ladder, tray, or trough types. Tray-type cable bridges feature surface treatments tailored to user needs: galvanizing, electrostatic spraying, and hot-dip galvanizing. Special anti-corrosion treatments are available for use in highly corrosive environments. Cable bridges are primarily used for various types of cables, such as computer cables, communication cables, thermocouple cables, and control cables for other highly sensitive systems. Regardless of the type of cable bridge, their dimensions are generally constant, requiring interconnecting components to connect the bridges during installation. However, this connection process can present the following drawbacks:

[0003] First, the widths of bridges of different sizes are inconsistent, and there is a lack of universal connection components to connect bridges of different widths.

[0004] Secondly, because the bridge is set to a fixed size, its length is uncertain during the actual laying process. When the laying length is not a multiple of the bridge length, it is necessary to cut the bridge or extend the laying distance, which leads to material waste or unreasonable laying structure. The connection components cannot extend the connection length, which also leads to material waste.

[0005] Finally, conventional bridge connection components are connected to the corresponding bridge with fixed dimensions. The overall structure is relatively three-dimensional, which takes up more space for transportation. The special structure cannot be disassembled and is not convenient for combined use.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] See also Figure 1-8 As shown, the utility model is a connection component of a large-span combined bridge, comprising two connecting seats 1, side plates 2, pads 3, connecting plates 4 and a connecting structure 5. A connecting structure 5 is provided between the two connecting seats 1. Each connecting seat 1 is slidably provided with symmetrically distributed side plates 2. The upper end of the connecting seat 1 is provided with two grooves 101. Two mounting blocks 102 are fixed in each groove 101. The two mounting blocks 102 in the same groove 101 are connected to a shaft 103 in a common rotation. The shaft 103 is provided with two threaded sections 104 with opposite thread directions; two sliders 202 are fixed to the bottom of the side plate 2, and the two sliders 202 at the bottom of the same side plate 2 are respectively threadedly connected to the outside of the threaded sections 104 on the two shafts 103;

[0034] The two connecting seats 1 are respectively connected to two adjacent bridges for use. A groove 101 is provided on the connecting seat 1 for installing the shaft 103 and assisting in the installation and adjustment of the side panels 2. The slider 202 at the bottom of the side panel 2 is placed in the groove 101 and connected to the threaded section 104 of the shaft 103. The slider 202 at the bottom of the other side panel 2 is connected to the other threaded section 104. The shaft 103 can then be rotated to rotate it. Under the action of the two oppositely threaded sections 104, the two side panels 2 will only move closer to or farther away from each other, thereby changing the width spacing of the subsequent installation of the bridge body 6.

[0035] The connecting structure 5 is overlapped with a backing plate 3, and the two side plates 2 on the two connecting seats 1 and on the same straight line are slidably connected with a connecting plate 4;

[0036] After the length of the connecting structure 5 is determined, a corresponding number of pads 3 are laid on the connecting structure 5 to avoid hollowing out the bottom, which facilitates the subsequent laying of cables. Finally, the connecting plate 4 is slid and connected to the side plates 2 on the two connecting seats 1 to block the sides of the space above the pads 3 to facilitate the laying of cables. According to actual needs, the side plates 2 and the connecting plate 4 can also be reinforced with connectors such as rivets 601;

[0037] The connecting structure 5 includes three adjusting rods 501 and sleeves 502 sleeved outside the three adjusting rods 501. A support rod 503 is symmetrically fixed outside each sleeve 502.

[0038] The end of the adjusting rod 501 away from the sleeve 502 is rotatably connected to the end surface of one connecting seat 1, and the end of the support rod 503 away from the sleeve 502 is fixedly connected to the end surface of the other connecting seat 1, and the adjusting rod 501 located in the middle is a screw rod, and the sleeve 502 located in the middle is an internally threaded tube;

[0039] When the length of the connecting component needs to be changed, the adjusting rod 501 with a screw in the middle is rotated to force the sleeve 502 with an internal threaded tube in the middle to move, so that the position of the sleeve 502 can be changed, and the other two side sleeves 502 also move on the adjusting rod 501 connected to it, thereby changing the distance between the two connecting seats 1, and thus changing the corresponding connection installation length. There is no need to cut the bridge frame for supplementation, and the connection length can be changed according to the actual distance between the two bridge frame bodies 6, which has high practical value.

[0040] A limiting notch 301 is provided at the bottom of the pad 3, and the pad 3 is clamped outside the corresponding support rod 503 and the adjustment rod 501 through the limiting notch 301;

[0041] The pad 3 is clamped on the corresponding connection structure 5 through the limiting notch 301 at the bottom thereof to prevent excessive sliding and displacement, making it easier to lay cables later.

[0042] The two side panels 2 on the same connecting base 1 are each provided with a slot 201 on the opposite sides thereof, and the two connecting plates 4 are provided with a clip 401 corresponding to the cross-sectional dimensions of the slot 201 on the opposite sides thereof. The connecting plates 4 are inserted into the slot 201 via the clip 401 to slideably connect with the side panels 2 on the two connecting bases 1 that are in the same straight line.

[0043] The card slot 201 cooperates with the setting of the card strip 401 to enable the connecting plate 4 to be slidably connected with the corresponding two side panels 2. First, the connecting plate 4 is connected to one side panel 2, and then the spacing of the corresponding connecting structure 5 is changed, and then the connecting plate 4 is slidably connected with the side panel 2 on the other connecting seat 1.

[0044] The two threaded sections 104 on the shaft 103 are respectively arranged outside the ends of the two mounting blocks 102 that are away from each other. The surface of the shaft 103 between the two mounting blocks 102 is smooth.

[0045] The shaft 103 can be rotated by manipulating the middle area of ​​the shaft 103 .

[0046] The upper surfaces of the two connecting bases 1 at opposite ends are provided with a first mounting groove 105. The opposing surfaces of the two side panels 2 on the same connecting base 1 are both provided with a second mounting groove 203, and the second mounting groove 203 is located at the end of the side panel 2 closer to the first mounting groove 105.

[0047] The two ends of the two connecting bases 1 that are away from each other are fixed with a bridge body 6, and the bottom of the bridge body 6 is embedded in the mounting groove 105 and fixed to the connecting base 1 through rivets 601. The two sides of the bridge body 6 are embedded in the mounting groove 203 on the inner side of the two side plates 2 and fixed to the side plates 2 through rivets 601.

[0048] Place the end of the bridge body 6 in the installation groove 1 105 temporarily, then rotate the shaft 103 in the connecting seat 1 to make the two side panels 2 approach each other until the installation groove 2 203 on the inner side of the two side panels 2 fit the two side surfaces of the bridge body 6 at the same time, determine the width size and then fix it with rivets 601 to complete the installation.

[0049] The specific working principle of the present invention is as follows: first, a bridge body 6 is fixedly connected to a connecting seat 1, the end of the bridge body 6 is placed in the installation groove 1 105, the shaft 103 in the connecting seat 1 is rotated to make the two side plates 2 approach each other until the installation grooves 203 on the inner sides of the two side plates 2 simultaneously fit the two side surfaces of the bridge body 6, and then the connecting seat 1 and the bridge body 6 are fixed with rivets 601; at this time, one end of the connecting plate 4 is slidably engaged with the side plate 2 on the connecting seat 1;

[0050] Then, the length of the connecting assembly is changed by rotating the adjusting rod 501 with a screw in the middle, forcing the sleeve 502 with an internal threaded tube in the middle to move, thereby changing the position of the sleeve 502. The other two side sleeves 502 also move on the adjusting rod 501 connected to them, thereby changing the distance between the two connecting seats 1 until the installation groove 105 in the other connecting seat 1 contacts the other bridge body 6 and stops. Then, the connecting seat 1 and the bridge body 6 are installed in the same way.

[0051] Finally, a corresponding number of pads 3 are overlapped and laid on the connecting structure 5, and then the connecting plate 4 is slid to connect with the side plates 2 on the two connecting seats 1 to block the side of the space above the pad 3 to facilitate the laying of cables. According to actual needs, the side plates 2 and the connecting plate 4 can also be reinforced with connectors such as rivets 601.

[0052] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
