Description

Technical Field

[0001] The invention relates to the technical field of cable installation equipment, in particular to a cable bridge. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, brackets and installation accessories. The cable trays in buildings can be erected independently or laid on various buildings (structures) and pipe gallery brackets.

[0003] At present, cable trays are widely used. Whether it is a cable tray rising from the ground or the plane of a building, or a cable tray arranged on a wall or roof, it may be deformed by irresistible torque, such as ground settlement, bracket corrosion, severe impact on the side, etc. The deformation of the cable tray may cause a large area of ​​the cable tray to collapse or break, resulting in cutting of cables and safety accidents.

[0004] In actual use, when the traditional cable tray is installed in a relatively hidden location, it is not easy for the staff to find when the cable tray is deformed, making it difficult to carry out timely repairs, posing a safety hazard. Summary of the invention

[0005] Based on this, in view of the problem that in actual use of traditional cable trays, when the installation position of the cable tray is relatively hidden, it is not easy for the staff to find the deformation of the cable tray, which makes it difficult to carry out timely repairs and there are safety hazards, a cable tray is proposed. The cable tray can locate the deformation position in time when it is deformed, so as to timely discover and repair it, and at the same time avoid large-scale collapse or breakage of the cable tray.

[0006] The specific technical solutions are as follows:

[0007] On the one hand, the present application relates to a cable tray, comprising a bracket assembly and a positioning assembly, the bracket assembly comprising a first bracket section, a second bracket section and a buffer, the first bracket section is connected to the second bracket section through the buffer; the positioning assembly is connected to the buffer; the positioning assembly is configured to start a positioning mode when the buffer section produces a preset deformation amount under the action of the first bracket section and / or the second bracket section or when the buffer section produces a preset deformation amount under the action of other external forces.

[0008] The technical solution is further described below:

[0009] In one embodiment, the positioning assembly includes a trigger member and a positioning unit, the positioning unit is connected to one of the first bracket section and the second bracket section, one end of the trigger member is connected to the buffer member, and the other end of the trigger member is detachably connected to the trigger end of the positioning unit;

[0010] The buffer can drive the trigger to separate from the trigger end of the positioning unit by deformation, so that the positioning unit starts the positioning mode. In this way, when at least one of the first bracket section and the second bracket section is deformed, the buffer will be deformed. At this time, the buffer will apply a pulling force to the trigger during the deformation process, thereby causing the trigger to separate from the trigger end of the positioning unit. At this time, the positioning unit starts the positioning mode and informs the user of the deformed position of the cable tray, so that the user can quickly maintain the cable tray.

[0011] In one embodiment, the positioning unit includes a proximity switch connected to one of the first bracket section or the second bracket section;

[0012] The trigger member includes a mounting sleeve, an induction body and a connector, one end of the connector is connected to the buffer member, the other end of the connector is connected to the mounting sleeve, the induction body is arranged in the mounting sleeve, the trigger member is mounted on the proximity switch through the mounting sleeve, and the induction body is inductively matched with the trigger end of the proximity switch;

[0013] The trigger member pulls the mounting sleeve off the proximity switch through the connector to trigger the proximity switch to send a positioning signal. In this way, when the first bracket section and / or the second bracket section are deformed by force, the buffer member will also be deformed. At this time, the buffer member will pull the connector when deformed, and the trigger member pulls the mounting sleeve off the proximity switch through the connector to trigger the proximity switch to send a positioning signal.

[0014] In one embodiment, the mounting sleeve is formed with a hook, and the connecting body is connected to the hook.

[0015] In one embodiment, the connecting body is a rope.

[0016] In one embodiment, the sensing body is a metal body. Thus, the proximity switch determines whether to send a positioning signal by sensing the position of the metal body.

[0017] In one embodiment, one end of the connector is simultaneously connected to the buffer and the other of the first bracket section or the second bracket section.

[0018] In one embodiment, one end of the connector is connected to the buffer member by a buckle and connected to the other of the first bracket section and the second bracket section by a screw; or

[0019] One end of the connector is connected to the buffer member via a screw and is connected to the other of the first bracket section and the second bracket section via a buckle.

[0020] In one embodiment, the thickness of the buffer is equal to or nearly equal to the thickness of the first bracket section and / or the second bracket section. Thus, when a cable is arranged inside the buffer, the punch has sufficient strength to support the cable alone.

[0021] In one embodiment, the buffer member is a bellows.

[0022] In one embodiment, the buffer component and the first bracket section as well as the buffer component and the second bracket section can be connected by riveting, welding, clamping or screw connection or a combination thereof.

[0023] When the cable tray is in use, when at least one of the first bracket and the second bracket is deformed, the buffer will be deformed, and the buffer plays a buffering role to avoid the direct breakage of the connection between the first bracket and the second bracket, thereby avoiding large-scale collapse or breakage of the cable tray. When at least one of the first bracket and the second bracket is deformed, the buffer is deformed or the buffer produces a preset deformation amount under the action of other external forces, the positioning component starts the positioning mode, and then the user can be notified of the position where the cable tray is deformed, so that the user can send someone for repair in time.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] At present, cable trays are widely used. Whether it is a cable tray rising from the ground or the plane of a building, or a cable tray arranged on a wall or a roof, it may be deformed by an irresistible torque. For example, ground settlement, bracket corrosion, severe impact on the side, etc. may cause deformation of the cable tray. When the cable tray is deformed, it may cause a large area of ​​the cable tray to collapse or break, resulting in cutting the cables and causing safety accidents. In actual use, when the installation position of the traditional cable tray is relatively hidden, it is not easy for the staff to find the deformation of the cable tray, and it is difficult to achieve timely repairs, which poses a safety hazard. Based on this, the present application proposes a cable tray 10, which can locate the deformation position in time when the cable tray 10 is deformed, so as to timely discover and repair it, and at the same time avoid the large-scale collapse or breakage of the cable tray 10.

[0037] Please refer to Figure 1 , Figure 1 The schematic diagram of the structure of a cable tray 10 in an embodiment is shown. The cable tray 10 in this embodiment includes a bracket assembly 100. The bracket assembly 100 includes a first bracket section 110, a second bracket section 120 and a buffer 130. The first bracket section 110 is connected to the second bracket section 120 through the buffer 130. The buffer 130 mainly plays a buffering role. When the first bracket section 110 and the second bracket section 120 are deformed by external force, the cable tray 10 will not directly suffer a rigid fracture under the buffering effect of the buffer 130. In addition, the buffer 130 plays a certain supporting role when the first bracket section 110 and / or the second bracket section 120 are deformed.

[0038] There are many ways to install the buffer 130 on the first bracket section 110 and the second bracket section 120; for example, in some embodiments, the buffer 130 and the first bracket section 110 and the second bracket section 120 are connected by welding or riveting; or in some embodiments, the buffer 130 and the first bracket section 110 and the second bracket section 120 are fastened by screws. Or in some embodiments, the buffer 130 and the first bracket section 110 and the second bracket section 120 are connected by welding or a combination of riveting or screws.

[0039] Please refer to Figure 2 In this embodiment, the first section bracket 110 and the buffer 130, as well as the second section bracket 120 and the buffer 130, are connected by means of screws; wherein, in order to improve the assembly stability between the first section bracket 110 and the buffer 130, as well as between the second section bracket 120 and the buffer 130, a plurality of screws may be provided and arranged according to a certain rule.

[0040] In which, a cable tray 10 may include multiple first-section brackets 110 and multiple second-section brackets 120, and two adjacent first-section brackets 110 and second-section brackets 120 are connected by a buffer 130; or, a cable tray 10 only includes one first-section bracket 110 and one second-section bracket 120, and the first-section bracket 110 and the second-section bracket 120 are connected by a buffer 130.

[0041] The buffer 130 may be a bellows, which may be made of metal or other materials with similar strength to metal. Due to its own corrugated structure, when the first bracket section 110 and / or the second bracket section 120 are deformed under stress, the bellows may shrink and deform along the contraction direction to shrink into a tubular structure with higher strength, thus playing a role of buffering and supporting the first bracket section 110 and the second bracket section 120.

[0042] Or in other embodiments, the buffer 130 may also be a rubber tube with certain strength and good toughness or a metal plate with high toughness.

[0043] Since the buffer 130 needs to be installed with cables, in order to make the buffer 130 have sufficient strength to support the cables alone, in some embodiments, the thickness of the buffer 130 is equal to or nearly equal to the thickness of the first bracket section 110 and / or the second bracket section 120. The thickness of the buffer 130 being nearly equal to the thickness of the first bracket section 110 and / or the second bracket section 120 may be a thickness difference of 0.1 mm to 0.5 mm.

[0044] For further information, please refer to Figure 2 , Figure 2 The schematic diagram of the structure of the cable tray 10 in one embodiment from one perspective. In this embodiment, the cable tray 10 further includes a positioning assembly 200, which is connected to the buffer 130; the positioning assembly 200 is configured to start the positioning mode when the buffer 130 generates a preset deformation amount under the action of the first bracket 110 or the second bracket 120, or generates a preset deformation amount under the joint action of the first bracket 110 and the second bracket 120, or generates a preset deformation amount under the action of other external forces. The preset deformation amount can be set as needed, and no further details will be given here.

[0045] Therefore, when the above-mentioned cable tray 10 is in use, when at least one of the first section bracket 110 and the second section bracket 120 is deformed, the buffer 130 will be deformed, and the buffer 130 plays a buffering role, thereby avoiding direct breakage of the connection between the first section bracket 110 and the second section bracket 120; further, when at least one of the first section bracket 110 and the second section bracket 120 is deformed, driving the buffer 130 to deform to a preset deformation amount or the buffer 130 produces a preset deformation amount under the action of other external forces, when the buffer 130 undergoes a preset deformation amount, the positioning component 200 starts the positioning mode, thereby notifying the user of the position where the cable tray 10 is deformed, so that the user can send someone for repair in time.

[0046] The preset deformation amount generated by the buffer 130 under the action of the external force may be that the external force directly acts on the buffer 130 to cause the buffer 130 to deform and then trigger the positioning assembly 200 to start the positioning mode.

[0047] Please refer to Figure 3 and Figure 4 ,in Figure 3 for Figure 1 AA section view in the figure, Figure 4 : is a schematic diagram of the structure of the positioning assembly 200 in one embodiment. In some embodiments, the positioning assembly 200 includes a trigger 210 and a positioning unit 220, the positioning unit 220 is connected to one of the first section bracket 110 and the second section bracket 120, one end of the trigger 210 is connected to the buffer 130, and the other end of the trigger 210 is detachably connected to the trigger end of the positioning unit 220. The buffer 130 can drive the trigger 210 to separate from the trigger end of the positioning unit 220 by deformation so that the positioning unit 220 starts the positioning mode. In this way, when the first section bracket 110 is deformed or the second section bracket 120 is deformed or the first section bracket 110 and the second section bracket 120 are deformed at the same time, the buffer component 130 will be deformed. At this time, the buffer component 130 will apply a pulling force to the trigger component 210 during the deformation process, thereby causing the trigger component 210 to separate from the trigger end of the positioning unit 220. At this time, the positioning unit 220 starts the positioning mode, and can then inform the user of the deformation position of the cable tray 10, so that the user can quickly maintain the cable tray 10.

[0048] Specifically in one embodiment, the positioning unit 220 includes a proximity switch, and the proximity switch is connected to one of the first bracket 110 and the second bracket 120. For example, please refer to Figure 3In the optional structure of the cable tray 10 shown in this embodiment, the positioning unit 220 is fixed to the second section bracket 120, and the positioning unit 220 and the second section bracket 120 can be fixed by screw connection or fixed by other methods such as clamping or riveting.

[0049] The trigger member 210 includes a mounting sleeve 212, a sensing body 214 and a connecting body 216. One end of the connecting body 216 is connected to the buffer member 130, and the other end of the connecting body 216 is connected to the mounting sleeve 212. The sensing body 214 is arranged in the mounting sleeve 212. The trigger member 210 is mounted on the proximity switch through the mounting sleeve 212, and the sensing body 214 is inductively matched with the trigger end of the proximity switch; when the first section bracket 110 is deformed or the second section bracket 120 is deformed or the first section bracket 110 and the second section bracket 120 are deformed at the same time, the buffer member 130 will also be deformed. At this time, the buffer member 130 will pull the connecting body 216 when deformed, and the trigger member 210 pulls the mounting sleeve 212 to separate from the proximity switch through the connecting body 216 to trigger the proximity switch to send a positioning signal. At this time, the proximity switch can transmit the positioning signal to the PLC (Programmable Logic Controller). The PLC can group and number the proximity switches according to the signal transmitted by the proximity switch and pass the result of the program running to the configuration software. The configuration software determines the position of the proximity switch where the action occurs based on the signal received from the PLC and issues an alarm message.

[0050] It should be noted that the proximity switch transmits the positioning signal to the PLC, the PLC groups and numbers the proximity switches and transmits the results of the program operation to the configuration software, and the configuration software determines the position of the proximity switch where the action occurs based on the signal received from the PLC and issues an alarm message. The steps and procedures involved in the interaction process can be implemented through existing technologies and will not be elaborated on here.

[0051] Please refer to Figure 4 In some embodiments, the mounting sleeve 212 is formed with a hook 2122, and the connecting body 216 is connected to the hook 2122. In this way, the connecting body 216 pulls the hook 2122 to drive the mounting sleeve 212 to separate from the proximity switch. The hook 2122 can have various shapes, such as square, round or oval. The specific shape of the hook 2122 can be set as needed.

[0052] In some other embodiments, the mounting sleeve 212 may also form a hanging ring or a protrusion for binding with the connecting body 216 .

[0053] Optionally, in some embodiments, the connector 216 may be configured as a rope, wherein the rope may be a steel wire rope or a rope made of other materials, so that when the buffer 130 is deformed, the rope may be driven to pull the mounting sleeve 212 away from the proximity switch.

[0054] Optionally, in some embodiments, the sensing body 214 is configured as a metal body, and when the positioning unit 220 is a proximity switch, the proximity switch can determine whether to send a positioning signal by sensing the position of the metal body. The shape of the metal body can be a square block, a bar block, or other irregular block structures.

[0055] In order to ensure the reliability of the proximity switch positioning, in some embodiments, there can be at least two proximity switches, and the mounting sleeves 212 are also correspondingly set to be more than two, one mounting sleeve 212 is correspondingly mounted on one proximity switch, and one sensing body 214 is correspondingly set in one mounting sleeve 212. A connector 216 is connected to at least two mounting sleeves 212 at the same time. In this way, even if one of the mounting sleeves 212 and the corresponding proximity switch falls with the cable tray 10, at least one of the remaining mounting sleeves 212 will be pulled off, thereby prompting the corresponding proximity switch to send a positioning signal. Among them, the number of corresponding proximity switches and mounting sleeves 212 can be set as needed, and will not be repeated here.

[0056] In some embodiments, one end of the connector 216 is connected to the buffer 130 and the other of the first bracket 110 and the second bracket 120. Figure 3 The proximity switch is fixed on the second bracket 120, one end of the connector 216 is connected to the mounting sleeve 212, and the other end of the connector 216 is connected to the buffer 130 and the first bracket 110. When installing the connector 216, the connector 216 should not be fixed too tightly on the buffer 130, so that the buffer 130 can pull the connector 216 when it is deformed, so that the connector 216 can shrink together with the buffer 130, and then the connector 216 can pull the mounting sleeve 212.

[0057] Specifically in one embodiment, one end of the connector 216 is connected to the buffer 130 by a buckle and is connected to the other of the first bracket section 110 and the second bracket section 120 by a screw.

[0058] In other embodiments, one end of the connector 216 is connected to the buffer 130 by means of screws and is connected to the other one of the first bracket section 110 and the second bracket section 120 by means of buckles.
