Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bridge hoisting, especially to cable bridge track installation device. BACKGROUND

[0002] The track installation device is a device for installing, adjusting and fixing the track system in the fields of construction, machinery, transportation, etc. The cable bridge needs to be installed at a certain height and angle. The track installation device can ensure the accurate installation position of the cable bridge and avoid deviation. In order to easily ensure that the gap, levelness and support angle between the bridge and the building structure meet the requirements, the cable bridge track installation device is needed.

[0003] The cable bridge track installation device can be divided into several types, including fixed track installation device, adjustable track installation device and hanging track installation device, etc. The adjustable track installation device allows fine adjustment of the position of the cable bridge during installation or after installation. Through sliding or rotating track, the height and angle of the cable bridge can be accurately adjusted.

[0004] However, the existing technology has certain problems in actual application. Especially in the vibration environment, since the bridge track usually adopts a rigid support directly fixed on the ceiling or support structure, when subjected to vibration or impact, the rigid connection mode is difficult to effectively buffer external force, causing the support connection part to easily loosen, and even the risk of bridge falling. This situation not only affects the safe operation of the cable, but also causes safety hazards to construction personnel and equipment. Therefore, how to improve the anti-seismic performance of the bridge track installation device and enhance its stability in the vibration environment has become a problem to be solved in the engineering field. UTILITY MODEL CONTENTS

[0005] In order to make up for the above shortcomings, the utility model provides a cable bridge track installation device, aiming at improving the problem that the bridge track is directly fixed on the ceiling through the support during installation and is easy to loosen and fall when subjected to vibration.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: the cable bridge track installation device comprises a cross beam, a connecting block is rotatably connected at both ends of the cross beam, a connecting rod is fixedly connected to the outer wall of the connecting block, and an anti-seismic assembly is arranged in the connecting rod.

[0007] The anti-seismic assembly includes a limiting block one, the limiting block one is slidably connected in the connecting rod, a spring damper is fixedly connected to the bottom of the limiting block one, the output end of the spring damper is connected with the inside of the connecting rod, a telescopic rod one is fixedly connected to the top of the limiting block one, a connecting plate is fixedly connected to one end of the telescopic rod one, a reset assembly is arranged on the outer wall of the telescopic rod one, a bridge is arranged on the top of the cross beam, and connecting tongues are fixedly connected to the two sides of the bridge.

[0009] The reset assembly includes a first spring, the first spring is sleeved on the outer wall, one end of the first spring is fixedly connected to the top of the limiting block one, and the other end of the first spring is fixedly connected to the inside of the connecting rod.

[0010] As a further description of the above technical solution:

[0011] The cross beam is slidably connected with a sliding block, and a limiting groove is formed in the sliding block.

[0012] As a further description of the above technical solution:

[0022] The utility model has the advantages of the following:

[0023] 1. In this utility model, when vibration occurs, one end of the connecting plate compresses the first spring through its connection with the spring damper. When the tension of the first spring is restored, the output end of the spring damper abuts against the inside of the connecting rod to absorb and buffer the vibration, thus achieving the effect of vibration resistance. This solves the problem that when the cable tray is installed, it is directly fixed to the ceiling by the bracket and is easy to loosen and fall off when subjected to vibration, thereby improving the stability of the cable tray.

[0024] 2. In this utility model, the slider is pre-positioned by the engagement of the second toothed block with the first toothed block.

When the crossbeam is connected to the bridge frame, the fastening bolt is connected to the slider by the connecting tongue, which achieves the effect of pre-positioning when the track is installed. This solves the problem that the operator needs to hold the track when it is installed on the crossbeam, and improves the convenience of the bridge frame track. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 and Figure 2The utility model provides a kind of embodiment: cable bridge track mounting device, including crossbeam 1, crossbeam 1 is installed as the main support structure of bridge 9, its both ends are rotatably connected with connecting block 2, connecting block 2 is provided with the stable connection between the help to realize crossbeam 1 and connecting rod 3, while providing certain angle adjustment ability, to adapt to the needs of different installation environment.

[0032] Anti-seismic component includes limit block one 4, limit block one 4 is slidably connected in connecting rod 3, can be displaced along connecting rod 3 when vibration occurs, to absorb part of impact force, reduce the influence of vibration to bridge 9.Limit block one 4 bottom is fixedly connected with spring damper 5, the output end of spring damper 5 is connected with connecting rod 3 inside, when being subjected to vibration, spring damper 5 can effectively buffer external force by the action of internal damping medium, and gradually restore to initial state after external force disappears, to prevent bridge 9 from loosening or falling off due to violent vibration.Limit block one 4 top is fixedly connected with telescopic rod one 6, telescopic rod one 6 can freely extend under the action of external force, to provide additional buffer stroke, improve the buffer capacity of entire anti-seismic component, telescopic rod one 6 one end is fixedly connected with connecting plate 7, connecting plate 7 is used to connect connecting rod 3 with building structure, so that the entire device can be stably installed on ceiling or wall.Telescopic rod one 6 outer wall is provided with reset component, to ensure that telescopic rod one 6 can restore to initial state after vibration disappears, maintain the stability of overall structure.Crossbeam 1 top is provided with bridge 9, bridge 9 is used to support and protect cable, and provide reliable installation space.Both sides of bridge 9 are fixedly connected with connecting tongue piece 10, the setting of connecting tongue piece 10 helps to improve the connection stability between bridge 9 and crossbeam 1, to prevent bridge 9 from displacement or loosening under the action of external vibration.Reset component includes first spring 8, first spring 8 is sleeved on telescopic rod one 6 outer wall, and provides elastic restoring force under the action of vibration.First spring 8 one end is fixedly connected at limit block one 4 top, to ensure that limit block one 4 can quickly reset after vibration buffering ends, improve the anti-seismic performance of entire device.The other end of first spring 8 is fixedly connected in connecting rod 3, to ensure that entire reset component can provide stable springback force, maintain the normal installation state of bridge 9.

[0033] Specifically, the crossbeam 1 is stably connected with the ceiling through the connecting rod 3, and the connecting plate 7 at the top of the connecting rod 3 is fastened with the ceiling through expansion bolts, thereby ensuring the stability of the crossbeam 1. Then, when the system is shaken, one end of the connecting plate 7 is connected with the spring damper 5 through the connecting piece telescopic rod 6, so that the first spring 8 inside the spring damper 5 is compressed, thereby relieving the impact force of the shock. After the vibration stops, the first spring 8 resets the spring damper 5 by virtue of its inherent tension, so that the spring damper 5 returns to its original position. At the same time, the output end of the spring damper 5 effectively contacts the inside of the connecting rod 3, absorbs and buffers the energy generated by the vibration, thereby reducing the impact of the vibration on the structure.

[0034] With reference to Figure 3The sliding block 13 is slidably connected inside the cross beam 1, and serves as a support and adjusting component for the installation of the bridge 9 on the cross beam 1. A limiting groove 15 is formed inside the sliding block 13, which is used to limit the movement range of the sliding block 13 inside the cross beam 1, so as to ensure that the sliding block 13 can slide and adjust the position in the specified track. The limiting block two 11 is fixedly connected inside the cross beam 1, and is slidably connected inside the limiting groove 15, so that the sliding block 13 can move stably along the guiding action of the limiting block two 11 during adjustment, avoiding deviation or shaking of the sliding block 13, improving the stability of the installation of the bridge 9. The limiting plate 16 is slidably connected inside the sliding block 13, and can slide and adjust along the preset track inside the sliding block 13, so as to ensure that the sliding block 13 can be smoothly positioned and fixed. The tooth block two 17 is fixedly connected to the bottom of the limiting plate 16, so that the sliding block 13 can be embedded with the fixed structure inside the cross beam 1 after being adjusted to the appropriate position, so as to improve the fixing strength of the sliding block 13. The tooth block one 12 is fixedly connected inside the cross beam 1 and is embedded with the tooth block two 17, so that the tooth block one 12 and the tooth block two 17 can be tightly matched after the sliding block 13 is adjusted to the target position, realizing stable positioning and avoiding accidental movement of the sliding block 13 due to external force. The telescopic rod two 18 is provided inside the sliding block 13 and can provide elastic support during adjustment of the sliding block 13, so that the sliding block 13 can maintain appropriate adjustment space under different working conditions. The second spring 19 is sleeved on the outer wall of the telescopic rod two 18 and assists the telescopic rod two 18 in supporting and resetting through elastic action, so as to ensure that the sliding block 13 can automatically reset after being released and fixed, improving the convenience of adjustment. The telescopic rod two 18 and the second spring 19 are both fixedly connected to the top of the limiting plate 16, so that the limiting plate 16 can always be elastically supported during sliding, ensuring that the tooth block two 17 and the tooth block one 12 can be more stably embedded during positioning. The telescopic rod two 18 and the second spring 19 are both fixedly connected inside the sliding block 13, so as to ensure that the sliding block 13 can reset and maintain a stable state by relying on the spring force during installation and adjustment. The tightening bolt 14 is threadedly connected inside the sliding block 13 and is used to finally fix the sliding block 13 after adjustment, so as to ensure that the sliding block 13 will not be displaced due to external force. The tightening bolt 14 is arranged inside the connecting tongue 10, and the connecting tongue 10 can be tightly pressed against the sliding block 13 by tightening the tightening bolt 14, realizing stable connection between the bridge 9 and the cross beam 1, so as to ensure the stability and safety of the bridge 9 after installation.

[0035] Specifically, when the bridge 9 is combined with the cross beam 1, first, the position of the sliding block 13 in the cross beam 1 is adjusted to ensure that the sliding block 13 can smoothly slide in the cross beam 1. Through the sliding of the sliding block 13, the sliding block 13 is precisely limited in the cross beam 1 by the cooperation of the limiting groove 15 and the outer wall of the limiting block two 11, thereby ensuring the stable position of the sliding block 13 in the cross beam 1. Then, the tooth block two 17 in the sliding block 13 is tightly embedded with the tooth block one 12 to complete the pre-positioning. The tooth block two 17 is precisely limited in the sliding block 13 by the limiting plate 16 and is supported by the tension of the second spring 19, so as to ensure that the tooth block two 17 is stable and does not shift during the embedding with the tooth block one 12. In this way, the tooth block two 17 can be firmly fixed with the tooth block one 12 to prevent any sliding or deviation. When the cross beam 1 is connected with the bridge 9, the fastening bolt 14 is further connected with the sliding block 13 through the connecting tongue 10, thereby further stabilizing the close cooperation of the overall structure.

[0036] Working principle: when the cable bridge track installation device is used, first, the cross beam 1 is connected with the ceiling through the connecting rod 3, and the connecting plate 7 at the top of the connecting rod 3 is connected with the ceiling through the expansion bolt. Then, when there is a vibration, one end of the connecting plate 7 is connected with the spring damper 5 through the telescopic rod one 6 to compress the first spring 8, and when the connecting plate 7 is reset through the tension of the first spring 8, the output end of the spring damper 5 abuts against the inside of the connecting rod 3 to absorb and buffer, thereby achieving the effect of anti-vibration.

[0037] When the bridge 9 is combined with the cross beam 1, first, the position of the sliding block 13 in the cross beam 1 is adjusted, and only by sliding the sliding block 13 in the cross beam 1, the sliding block 13 is limited by sliding in the limiting groove 15 on the outer wall of the limiting block two 11. Then, the sliding block 13 is pre-positioned by embedding the tooth block two 17 with the tooth block one 12, and the tooth block two 17 is limited in the sliding block 13 by the limiting plate 16 and is supported by the tension of the second spring 19, so as to enable the tooth block two 17 to be stably embedded with the tooth block one 12. Then, when the cross beam 1 is connected with the bridge 9, the fastening bolt 14 is connected with the sliding block 13 through the connecting tongue 10, thereby achieving the effect of pre-positioning during track installation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
