Description

Technical Field

[0001] The present invention relates to the technical field of cable bridges, and in particular to a fixing structure of a cable bridge and the cable bridge. Background Art

[0002] Cable trays are equipment specifically used for laying cables. They are mainly composed of brackets (U-shaped fixed structures) and trays. The brackets are used to stably fix the bracket arms to the ceiling, while the trays are used to support the cables, ensuring that the cables are routed in an orderly and secure manner. Cables laid through cable trays are exposed to the outside, making cable maintenance easy.

[0003] The existing cable trays, for example, a cable tray installation structure disclosed in Chinese patent application No. CN118040575A and a combined cable tray with a fixed structure disclosed in Chinese patent application No. CN114421385A, all of these cable trays are fixed to the ceiling by the fixing structure of the U-shaped fixing frame. However, when laying cables, due to the uncertainty of the direction of the cables and the subsequent increase or decrease of cables, one side of the U-shaped fixing frame needs to be disassembled so that the cables can be laid on the cable tray. When one side of the U-shaped fixing frame is disassembled, the forces on both sides of the cable tray will be uneven, causing the cable tray to collapse easily. Although increasing the density of the U-shaped fixing frame can avoid affecting the stability of the cable tray when disassembling a single U-shaped fixing frame, the increased density of the U-shaped fixing frame will greatly reduce the efficiency of cable laying, which is not conducive to the upgrade and modification of cables in the cable tray.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figures 1-15 As shown, a fixing structure of a cable bridge is disclosed, the fixing part 1 includes a mounting bottom sleeve 11, which is used to cover the bottom surface of the bridge body 2, and the top surfaces of both sides of the mounting bottom sleeve 11 are fixedly connected with a mounting connector. The mounting connector automatically opens a gap to maintain the connection force between the mounting bottom sleeve 11 and the bridge body 2, while allowing the cable to enter the interior of the bridge body 2 through the gap. A mounting top plate 14 is fixedly connected to the top of the mounting connector, and the mounting top plate 14 is fixedly connected to the ceiling by bolts. A limiting structure 15 is provided on the side of the mounting bottom sleeve 11. The limiting structure 15 is used to limit the position of the mounting bottom sleeve 11 on the side surface of the bridge body 2, so that the mounting bottom sleeve 11 is stable on the side surface of the bridge body 2. It should be noted that the mounting bottom sleeve 11 is fixed to the side surface of the bridge body 2. The bottom sleeve 11 fits with the bridge body 2, and the bottom sleeve 11 will be nested in the bottom surface of the bridge body 2. The spacing of the bottom sleeve 11 on the bottom surface of the bridge body 2 is adaptively selected by those skilled in the art according to the actual situation of the bridge body 2, ensuring that the bottom sleeve 11 can effectively support the bridge body 2 and the cables inside the bridge body 2. The bottom sleeve 11 is fixedly connected to the mounting top plate 14 through the erection connector, and the mounting top plate 14 is fixed to the ceiling by bolts. The mounting top plate 14 can also be fixedly connected to the ceiling by other means such as welding. In this way, the mounting top plate 14 can limit the bridge body 2 to the high space in the room by erecting the connector and the bottom sleeve 11, and will not occupy the position space in the room.

[0041] like Figure 14 As shown, when the bridge body 2 is needed to lay cables, the bridge body 2 is usually installed in advance. Figure 14 The bridge body 2 is shown to be in a T-shaped direction. The bridge body 2 can also be in an L-shaped or a cross-shaped direction. The specific arrangement of the bridge body 2 is adaptively selected by those skilled in the art according to the direction of the cables to be laid indoors. Figure 14What is given is a partial schematic diagram of the "T"-shaped direction of the bridge body 2. When the cable needs to be routed to the left, it is necessary to open a gap on the left side of the erection connector so that the cable can enter the bridge body 2 through the gap on the left side of the erection connector, thereby realizing the laying of the cable. When the cable needs to be routed to the right, it is necessary to open a gap on the right side of the erection connector so that the cable can enter the bridge body 2 through the gap on the left side of the erection connector. Therefore, by erecting the connector, the laying of cables in different directions on the bridge body 2 can be realized without affecting the overall firmness of the erection connector fixing the bridge body 2. When the erection connector opens the gap, the connection force between the installation bottom sleeve 11 and the bridge body 2 can also be maintained to ensure the lifting effect of the installation bottom sleeve 11 on the bridge body 2. The process of the erection connector maintaining the connection between the installation bottom sleeve 11 and the bridge body 2 is as follows:

[0042] like Figures 1-11 As shown, the erection connecting member is a shift rod connecting member 12, and the shift rod connecting member 12 includes a lower connecting rod 121, the bottom of the lower connecting rod 121 is fixedly connected to the top surface of the mounting bottom sleeve 11, the top of the lower connecting rod 121 is connected to a shift rod mechanism 122, the top of the shift rod mechanism 122 is connected to an upper connecting rod 123, the top of the upper connecting rod 123 is fixedly connected to the bottom surface of the mounting top plate 14, the bottom end of the lower connecting rod 121 and the top surface of the mounting bottom sleeve 11 are fixedly connected together by bolts, the lower connecting rod 121 is connected to the upper connecting rod 123 through the shift rod mechanism 122, and the top of the upper connecting rod 123 is fixedly connected to the bottom surface of the mounting top plate 14, so that the mounting bottom sleeve 11 can limit the bridge frame body 2 to the bottom of the mounting top plate 14.

[0043] like Figure 6 and Figure 7 As shown, the lever mechanism 122 includes a control lever 1221, a lock tongue mechanism 1222 is provided on the inner side of the control lever 1221, the top of the control lever 1221 is engaged with a transmission gear 1223, and the bottom of the transmission gear 1223 is engaged with a linkage limit rod 1224. It should be noted that the transmission gear 1223 is composed of a large gear and a small gear, and the large gear and the small gear are fixedly connected together, wherein the small gear is engaged with the top of the control lever 1221, and the bottom of the large gear is engaged with the top surface of the linkage limit rod 1224. When the top of the control lever 1221 rotates, it will drive the small gear to rotate, and the rotating small gear will drive the large gear to rotate synchronously, and the rotating large gear will drive the linkage limit rod 1224, causing the linkage limit rod 1224 to be displaced.

[0044] like Figure 6-Figure 9As shown, a hook groove 12211 is provided at the bottom of the control lever 1221, and a protrusion 1211 that fits with the hook groove 12211 is provided at the top of the lower connecting rod 121 near the hook groove 12211. When the control lever 1221 is in a vertical state, the hook groove 12211 at the bottom of the control lever 1221 just fits with the protrusion 1211 at the top of the lower connecting rod 121. The top of the control lever 1221 is fixedly connected to a rotating gear seat 12212, and the bottom surface of the upper connecting rod 123 is fixedly connected to an upper crossbeam 1231. The rotating gear seat 12212 is installed on the inner side of the upper crossbeam 1231 through a rotating shaft. The side of 1221 is provided with a locking groove 12213 that matches the linkage limit rod 1224 near the linkage limit rod 1224. It should be noted that the transmission gear 1223 is also installed on the inner side of the upper beam 1231 through the rotating shaft, wherein the small gear is engaged with the rotating gear seat 12212, and the control levers 1221 are symmetrically provided at both ends of the upper beam 1231. The interior of the upper beam 1231 is provided with a sliding groove that matches the linkage limit rod 1224 at the position corresponding to the linkage limit rod 1224, ensuring that the linkage limit rod 1224 can move freely in the upper beam 1231. When one of the control levers 1221 is rotated, it will achieve the following effect. Figure 7 In the state shown, for example, the right control lever 1221 (with Figure 7In the process of counterclockwise rotation (taking the positions of the two control levers 1221 in the right side as a reference), the rotating gear seat 12212 at the top of the right control lever 1221 will drive the transmission gear 1223 engaged with it to rotate clockwise, and the clockwise rotating transmission gear 1223 will drive the linkage limit rod 1224 engaged with it to move to the left, and a locking groove 12213 is provided on the side of the left control lever 1221 near the linkage limit rod 1224, so the linkage limit rod 1224 moving to the left will be embedded in the left control lever 1 221 side of the locking groove 12213, thereby achieving the locking of the left control lever 1221, that is, when the right control lever 1221 is rotated counterclockwise to open the gap, the position of the left control lever 1221 will be locked, ensuring that the left control lever 1221 is stable between the lower connecting rod 121 and the upper connecting rod 123, maintaining the connection force between the lower connecting rod 121 and the upper connecting rod 123, and now the cable can be put into the position between the two control levers 1221 through the gap opened by the right control lever 1221 , then rotate the right control lever 1221 to a vertical state, and then rotate the left control lever 1221 clockwise. The left control lever 1221 opens a gap and locks the position of the right control lever 1221, while also maintaining the connection force between the lower connecting rod 121 and the upper connecting rod 123. Then, pass the cable through the gap opened by the left control lever 1221, so that the cable can be laid on the bridge body 2, and finally rotate the left control lever 1221 to a vertical state. During the cable laying process, the technician The personnel must lay the cables according to the above process, that is, open one control lever 1221 while locking the other control lever 1221 to prevent the two control levers 1221 from being opened at the same time, resulting in uneven force on both sides of the bridge body 2, causing the bridge body 2 to tilt. This ensures that when the cables are laid, there is always a connecting force between the lower connecting rod 121 and the upper connecting rod 123, ensuring the supporting effect of the installation bottom sleeve 11 on the bridge body 2, preventing the bridge body 2 from collapsing due to uneven force, and improving the safety of the cable laying process.

[0045] like Figure 5-Figure 11As shown, the lock tongue mechanism 1222 includes a limiting lock tongue 12221, and a lock tongue groove 1212 that matches the limiting lock tongue 12221 is opened at the top of the lower connecting rod 121 near the limiting lock tongue 12221. The inner side of the limiting lock tongue 12221 is fixedly connected to a synchronization frame 12222, and the top side surface of the synchronization frame 12222 is fixedly connected to a control button 12223. The top end surface of the synchronization frame 12222 is fixedly connected to a linkage piston 12224. When the control lever 1221 is in a vertical state, the limiting lock tongue 12221 will move downward under the action of gravity and eventually be embedded in the lock tongue groove 1212 on the corresponding lower connecting rod 121. Through the cooperation between the limiting lock tongue 12221 and the lock tongue groove 1212 , which can lock the position of the control lever 1221 and prevent the control lever 1221 from rotating. After the position of the control lever 1221 is locked, the control lever 1221 can achieve a stable connection with the lower connecting rod 121 through the cooperation of the hook groove 12211 and the protrusion 1211. When the control lever 1221 needs to be rotated, it is only necessary to drive the control button 12223 to move the control button 12223 upward. The upward moving control button 12223 will drive the limiting lock tongue 12221 to move upward synchronously through the synchronous frame 12222, so that the limiting lock tongue 12221 is disengaged from the lock tongue groove 1212, thereby releasing the lock of the control lever 1221, allowing the control lever 1221 to rotate freely and open the gap.

[0046] like Figure 5-Figure 11 As shown, a piston cavity that matches the linkage piston 12224 is provided in the interior of the control lever 1221 near the linkage piston 12224, and the top of the piston cavity is connected to a linkage limiting mechanism 1225 through an oil pipe, wherein the linkage limiting mechanism 1225 includes a piston cylinder 12251, a limiting cavity 12253 is provided in the middle position of the piston cylinder 12251, and oil delivery pipes 12252 are connected to the two ends of the piston cylinder 12251, and the oil delivery pipes 12252 at both ends are respectively communicated with the top of the piston cavity in the control lever 1221 on both sides of the upper crossbeam 1231, and two symmetrical limiting pistons 12254 are provided in the piston cylinder 12251, and the distance between the two symmetrical linkage pistons 12224 is equal to 1.2 times to 1.5 times the depth of the limiting lock tongue 12221 embedded in the lock tongue groove 1212;

[0047] When one of the limit lock tongues 12221 moves upward under the drive of the control button 12223, it will also drive the linkage piston 12224 through the synchronous frame 12222, so that the linkage piston 12224 moves upward in the piston cavity, and the hydraulic oil in the piston cavity is delivered to the inner side of the corresponding limit piston 12254 through the oil delivery pipe 12252, so that the limit piston 12254 moves in the piston cylinder 12251. Since the distance between the two symmetrical linkage pistons 12224 is equal to 1.2 to 1.5 times the depth of the limit lock tongue 12221 embedded in the lock tongue groove 1212, when one of the limit lock tongues 12221 moves upward, the linkage piston 12224 will move upward in the piston cavity. When the limiting lock tongue 12221 is separated from the lock tongue groove 1212, the distance between the two symmetrical linkage pistons 12224 is only 0.2 to 0.5 times the depth of the limiting lock tongue 12221 embedded in the lock tongue groove 1212. That is to say, after the limiting lock tongue 12221 corresponding to one of the control levers 1221 is separated from the lock tongue groove 1212 and unlocked, the limiting lock tongue 12221 corresponding to the other control lever 1221 cannot be completely separated from the lock tongue groove 1212, thereby locking the limiting lock tongue 12221 on the other control lever 1221, preventing the two control levers 1221 from being opened at the same time.

[0048] When one of the control levers 1221 rotates to open the gap, the other control lever 1221 will be locked by the linkage limit lever 1224, which also prevents the two control levers 1221 from being opened at the same time. This ensures that when the cables are laid, there is always a connecting force between the lower connecting rod 121 and the upper connecting rod 123, ensuring the lifting effect of the installation bottom sleeve 11 on the bridge frame body 2. Therefore, after optimizing the setting density of the fixing parts 1, that is, ensuring the lifting effect on the bridge frame body 2, the minimum number of fixing parts 1 can be retained, which is convenient for the subsequent upgrading and modification of the cables in the bridge frame body 2. Therefore, the bridge frame body 2 is lifted by the set fixing parts 1, which ensures the efficiency of cable laying in the bridge frame body 2 and avoids the uneven force on the bridge frame body 2 during the cable laying process.

[0049] like Figure 10 and Figure 14As shown, the limiting structure 15 includes a limiting plate 151, the inner side of the limiting plate 151 is fixedly connected to a limiting key 152, and the outer center position of the limiting plate 151 is connected to a pressure cylinder 153 through a spring. It should be noted that the provided limiting key 152 can cooperate with the bridge body 2 to limit the position of the installation bottom sleeve 11 on the bridge body 2, so that the installation bottom sleeve 11 can be fixed on the bridge body 2, ensuring the stability and firmness of the cooperation between the fixing member 1 and the bridge body 2. The inner side of the pressure cylinder 153 is The end is threadedly connected to the side of the mounting sleeve 11 by bolts, and a pressure spring is embedded in the side of the pressure cylinder 153. The outer end of the pressure cylinder 153 is used to support the outer end of the spring, and the inner end of the pressure spring directly acts on the limit plate 151, so that the limit plate 151 has pressure toward the side of the mounting sleeve 11. A through hole that matches the limit key 152 should be opened on the mounting sleeve 11 near the limit key 152 to ensure that the limit key 152 can pass through the through hole and cooperate with the bridge body 2.

[0050] Example 2

[0051] like Figure 11-13 As shown, the circular ring connector 13 includes a lower docking rod 131 and an upper docking rod 133, the top of the lower docking rod 131 is fixedly connected to a lower circular ring 132, the bottom end of the lower docking rod 131 is fixedly connected to the top surface of the mounting bottom sleeve 11, the bottom end of the upper docking rod 133 is fixedly connected to an upper circular ring 134, the top of the upper docking rod 133 is fixedly connected to the bottom surface of the mounting top plate 14, and a rotating circular ring 135 is inserted between the lower circular ring 132 and the upper circular ring 134. It should be noted that the upper circular ring 134 has the same structure as the lower circular ring 132, both are arc-shaped, and the ring shape formed by the upper circular ring 134 and the lower circular ring 132 is matched with the rotating circular ring 135, so the lower circular ring 132 and the upper circular ring 134 have a corresponding inner portion. The rotating groove that fits the rotating ring 135 allows the rotating ring 135 to rotate freely between the lower ring 132 and the upper ring 134. The lengths of the lower ring 132 and the upper ring 134 are both smaller than the semi-circular ring, so that there will be a gap between the lower ring 132 and the upper ring 134. When in use, the fixing part 1 is installed at equal distances on the side of the bridge body 2, and then the fixing part 1 is installed on the bottom surface of the mounting top plate 14 through the ring connector 13. The mounting top plate 14 is generally fixed to the ceiling by bolts or other means. By connecting the mounting top plate 14 with the ring connector 13, the bridge body 2 can be arranged at the bottom position of the ceiling, and then the bridge body 2 is used to lay the cables.

[0052] like Figure 13As shown, a notch is provided on the rotating ring 135, and the length of the notch is smaller than the length of the lower ring 132 or the length of the upper ring 134. Since the length of the notch provided on the rotating ring 135 is smaller than the length of the lower ring 132 or the length of the upper ring 134, when the notch is inside the lower ring 132 or the upper ring 134, the lower ring 132 or the upper ring 134 can cooperate with the rotating ring 135 to prevent the notch on the rotating ring 135 from separating through the lower ring 132 or the upper ring 134. When laying the cable, Figure 12 and Figure 13 For example, first drive the rotating ring 135 so that the notch on the rotating ring 135 is aligned with the gap on the left side between the lower ring 132 and the upper ring 134, then pass the cable through the notch on the rotating ring 135 and the gap on the left side between the lower ring 132 and the upper ring 134, and enter the inner side of the rotating ring 135, then drive the rotating ring 135 again so that the notch on the rotating ring 135 is aligned with the gap on the right side between the lower ring 132 and the upper ring 134, and then pass the cable through the notch on the rotating ring 135. As well as the gap on the right side between the lower ring 132 and the upper ring 134, the cable is laid on the bridge body 2. During the cable laying process, the lower docking rod 131 and the upper docking rod 133 are always connected by the rotating ring 135. That is, during the cable laying process, the connection force between the lower docking rod 131 and the upper docking rod 133 is guaranteed, and the lifting effect of the installation bottom sleeve 11 on the bridge body 2 is maintained, preventing the bridge body 2 from collapsing due to uneven force, thereby improving the safety of the cable laying process;

[0053] Since the rotating ring 135 is provided with a notch, the gravity of the half circle of the rotating ring 135 with the notch is less than the gravity of the half circle without the notch. In this way, the rotating ring 135 will rotate the notch on the rotating ring 135 to the inner middle position of the upper ring 134 under the action of its own gravity, and the rotating ring 135 can simultaneously seal the gaps on the left and right sides between the lower ring 132 and the upper ring 134.

[0054] The cam 136 is adapted to engage the cam 136 and engage the cam 137, and the cam 138 is adapted to engage the cam 139. The cam 139 is adapted to engage the cam 138, and the cam 139 is adapted to engage the cam 139.

[0055] Rollers can be installed on the inner walls of the lower ring 132 and the upper ring 134 at positions corresponding to the rotating ring 135. The rollers can reduce the friction when the rotating ring 135 rotates between the lower ring 132 and the upper ring 134, making the operation of the rotating ring 135 easier.

[0056] Example 3

[0057] like Figures 1-17 As shown, a cable tray is disclosed, including a tray body 2 and a fixing member 1 nested on the side of the tray body 2. It should be noted that the number of fixing members 1 and the spacing on the side of the tray body 2 can be set arbitrarily, ensuring that the fixing member 1 can fix the tray body 2 and the cables laid on the top of the tray body 2 to the ceiling. The above embodiment of laying the cables on the tray body 2 through the fixing member 1 has been described in detail and will not be repeated here.

[0058] A cable trough 21 is provided on the inner side of the bridge body 2, and bridge walls 22 are provided on both sides of the bridge body 2. A limit hole 23 is provided on the side of the bridge wall 22, and the limit hole 23 fits with the limit key 152. The installation bottom sleeve 11 can be stably connected to the bridge body 2 through the limit structure 15. The specific process is:

[0059] The limit key 152 provided can cooperate with the bridge body 2, specifically with the limit hole 23 on the cable trough 21, and limit the installation bottom sleeve 11 to the bridge body 2, so that the installation bottom sleeve 11 can be fixed on the bridge body 2, ensuring the stability and firmness of the cooperation between the fixing member 1 and the bridge body 2. The inner end of the pressure cylinder 153 is threadedly connected to the side of the installation bottom sleeve 11 by a bolt, and a pressure spring is embedded in the side of the pressure cylinder 153. The outer end of the pressure cylinder 153 is used for The support is on the outer end of the spring, and the inner end of the pressure spring directly acts on the limit plate 151, so that the limit plate 151 has pressure toward the side of the installation base sleeve 11. A through hole that matches the limit key 152 should be opened on the installation base sleeve 11 near the limit key 152 to ensure that the limit key 152 can pass through the through hole and cooperate with the limit hole 23 on the bridge body 2. The number and position of the limit holes 23 can be set arbitrarily to ensure that the side position of the fixing part 1 on the bridge body 2 can be adaptively adjusted.

[0060] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
