Description

Technical Field

[0001] The present invention relates to the technical field of cable laying devices, and particularly relates to a cable tray convenient for threading and a using method thereof. Background Art

[0002] In the complex cable laying environment of a computer room, with the high-density deployment of devices such as servers and switches, the number of cables in a single cabinet has increased several times compared to traditional scenarios, posing severe challenges to the threading convenience, heat dissipation performance, and signal stability of the cable tray. The existing cable trays in computer rooms generally have the following problems. When threading cables, the cable tray is often installed in semi-closed spaces such as ceiling interlayers and equipment gaps. It is difficult for construction workers to directly observe the positions of the through holes at both ends. When laying multiple cables simultaneously, it is easy to cause entanglement and knotting due to the lack of guidance, and the bending and extrusion of the cables may cause damage to the insulating layer or signal attenuation. In terms of heat dissipation design, a large number of cables are laid inside the cable tray, generating heat. However, the traditional cable tray does not address the problem of heat generated by multiple cables and relies on a single passive heat dissipation mode of the top heat sink, which will affect the service life of the cables. Therefore, there is an urgent need for a cable tray convenient for threading and a using method thereof. Summary of the Invention

[0003] The purpose of the present invention is to provide a cable tray convenient for threading and a using method thereof to solve the problems existing in the above-mentioned prior art.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A cable tray convenient for threading and a using method thereof, comprising: A housing, the front end and the rear end of the housing are both completely open.

The heat dissipation devices are fixedly connected to the inner bottom end of the housing. The heat dissipation devices are located on the left and right sides of the guiding device. The heat dissipation devices are used for dissipating heat from the cables; A buffering device, multiple buffering devices are provided. The buffering devices are fixedly connected to the inner bottom end of the housing. The buffering devices are located in front of and behind the guiding device. The buffering devices are used for restricting and buffering the cables; And a clamping device, multiple clamping devices are provided.

The guiding device is used for driving the clamping device to move. The clamping device is used for clamping the cables.

[0005] By adopting the above technical solutions, a three-dimensional convection channel is formed by the heat sink on the top of the outer shell, the ventilation holes on both sides and the ventilation grooves on the inner bottom. When it is necessary to dissipate the heat of the cables inside the cable bridge, the heat dissipation device is used to enhance the air flow inside, so that the cold air entering the cable bridge can flow along the inside of the cable bridge, reduce the temperature of the cables and extend the service life of the cables; the guiding device drives the movable clamping device to move the cables, which is convenient for threading the cables, and the buffering device reduces the abrasion of the cables when moving the cables.

[0006] In a further embodiment, the guiding device includes: Sliding rails, which are fixedly connected to the inner bottom end of the outer shell from front to back, and a wear-resistant layer is provided on the surface of the sliding rails; And sliders.

The sliders move in the front-back direction on the top of the sliding rails. Wire ropes are provided on the front side and the rear side of the sliders, and the wire ropes are used to drive the sliders to move in the front-back direction.

[0007] By adopting the above technical solutions, the wear-resistant layer on the surface of the sliding rails in the guiding device can significantly reduce the frictional loss of the slider movement, extend the service life of the cable bridge, and the sliders move the cables through the front and rear wire ropes, improving the construction efficiency when laying multiple cables.

[0008] In a further embodiment, the heat dissipation device includes: A temperature sensor, which is fixedly connected to the center position of the inner bottom end of the outer shell; And heat dissipation fans. A plurality of heat dissipation fans are provided, and the heat dissipation fans are fixedly connected to both ends inside the outer shell. Motors are arranged at intervals of the heat dissipation fans, and the heat dissipation fans are electrically connected to the motors. The start and stop of the fans are controlled according to the temperature of the temperature sensor, and the heat dissipation fans are used to cool the cables.

[0009] By adopting the above technical solutions, the heat dissipation device accurately monitors the temperature inside the outer shell through the temperature sensor, and realizes the heat dissipation of the cables by turning on the heat dissipation fans at both ends of the outer shell, improving the service life of the cables and the cable bridge.

[0010] In a further embodiment, the buffering device includes: Cross beams, which are fixedly connected to both sides of the inner wall of the outer shell at intervals, and a plurality of mounting holes are provided through the top ends of the cross beams; Round rods, which are slidably installed in the mounting holes. A first spring is sleeved on the top ends of the round rods, and the bottom ends of the first springs are fixedly connected to the top ends of the cross beams; Mounting plates, which are fixedly connected to the top ends of the round rods, and the bottom ends of the mounting plates are fixedly connected to the top ends of the first springs; A baffle plate, which is fixedly installed at the bottom end of the round rod; Lug plates. A plurality of lug plates are provided, and the lug plates are fixedly connected to the left and right ends of the baffle plate; A cylinder, both ends of which are rotatably connected to the lug plates through rotating shafts; And a limit block, which is fixedly connected to the inner top end of the housing. An arc-shaped through groove penetrating through the front and back corresponding to the cylinder is provided at the bottom end of the limit block.

[0011] By adopting the above technical solution, the bridge is flipped by 180°. The weight of the cable is all located on the cylinder. The cylinder is rotatably connected to the lug plate. When pulling the cable, the friction of the cable is reduced by rolling.

[0012] In a further embodiment, the clamping device includes: A first moving plate, which is located on the top of the slider. An installation hole penetrating through the left and right is provided at the center position on the left side of the first moving plate. A screw rod is rotatably installed in the installation hole. A nut integrally formed is provided at the left end of the screw rod. The nut is used to make the screw rod and the nut rotate synchronously; Struts. A plurality of struts are provided, and the left ends of the struts are fixedly connected to the right end of the first moving plate; A first clamping plate, which is spaced on the left end of the first moving plate. The first clamping plate is fixedly connected to the top of the slider. A hole corresponding to the screw rod is provided at the left end of the first clamping plate. The screw rod is rotatably installed in the hole. A plurality of through holes penetrating through the left and right are provided at the periphery of the left end of the first clamping plate. The struts are penetrated through the through holes; A second clamping plate, which is spaced on the right end of the first clamping plate. An arc-shaped clamping surface is provided on the side of the second clamping plate opposite to the first clamping plate. The second clamping plate and the first clamping plate are used to clamp and fix the cable; And a second moving plate, which is located on the top of the slider. The left end of the second moving plate is fixedly connected to the right end of the second clamping plate. The periphery of the left end of the second moving plate is fixedly connected to the right end of the strut. The strut is used to move the second clamping plate to control the distance between the first clamping plate and the second clamping plate.

[0013] By adopting the above technical solution, through the mechanical structure driven by the screw rod and linked with the strut, the precise linear displacement of the second clamping plate is realized, so that the arc-shaped clamping surface forms an adaptive wrapping and clamping on the cable. Rotating the nut can adjust the clamping distance with one hand operation, which not only ensures the compatibility of different wire diameters, but also avoids the tediousness of repeatedly screwing the traditional bolts. The strut ensures the parallel movement of the second clamping plate and prevents skewing from damaging the cable insulation layer.

[0014] In a further embodiment, a second spring is provided at the connection between the second clamping plate and the support column, and the second spring is used to prevent over-tightening from damaging the insulating layer.

[0015] By adopting the above technical solution, a buffer compensation mechanism is formed by utilizing the elastic deformation characteristics of the spring, avoiding rigid extrusion caused by manual over-tightening or vibration.

[0016] In a further embodiment, shielding coatings are provided on both the inner wall and the outer wall of the outer shell.

[0017] By adopting the above technical solution, through the double electromagnetic isolation of the inner and outer shielding coatings, external signal interference and crosstalk between internal cables are effectively suppressed, ensuring the stability of data transmission; at the same time, the coating has anti-corrosion and moisture-proof characteristics, improving the environmental adaptability of the cable tray, reducing the oxidation loss of the outer shell, and extending the overall service life. In a further embodiment, the diameter of the cylinder extends from the midpoint of the axis towards both ends of the cylinder, and the diameter of the cylinder gradually increases, and the cable always contacts the middle section surface of the cylinder.

[0018] By adopting the above technical solution, the diameter gradually increases from the center position of the cylinder axis towards both ends, so that the cable is always located at the center position of the cylinder, and the cable will not rub against the two side surfaces of the ear plate, thereby reducing the friction of the cable.

[0019] In a further embodiment, in step S1, the cable passes through the buffer device to perform preliminary positioning of the cable; Place the cable tray upright. Under the action of the first spring, the mounting plate, the round rod and the baffle move upward. The ear plates are fixedly connected to both ends of the mounting plate, and the cylinder is rotatably mounted on the ear plates. Thus, the cylinder moves upward, creating a gap between the cylinder and the limit block. Pass the cable through the gap between the limit block and the cylinder; In step S2, the cable passes through the clamping device to fix the cable; After the cable passes through the buffer device, place the handle through the gap between the cable devices on the nut, rotate the nut to drive the screw to rotate, so that the screw moves to the right, driving the first moving plate to move to the right, thereby driving the support column and the second moving plate to move away from the first moving plate, causing a gap between the first clamping plate and the second clamping plate. Pass the cable through the gap between the first clamping plate and the second clamping plate, and then rotate the nut through the handle to make the screw move to the left, so that the second clamping plate moves towards the position of the first clamping plate, causing the first clamping plate and the second clamping plate to fix the cable; In step S3, move the cable and pass the cable through the cable tray; Flip the cable tray by 180°. The weight of the cable is entirely at the center position of the cylinder. The first spring moves the cylinder upward to initially clamp the cable. Then, pull the cord at the rear of the slider, causing the slider to move backward along the slide rail. When the slider drives the clamping device to the corresponding position, stop pulling the cord, and the cable passes through the cable tray to complete the laying. Step S4: The temperature induction triggers the start of the heat dissipation device. When the temperature sensor inside the housing detects that the temperature of the cable exceeds a certain value, the signal of the temperature sensor is transmitted to the motor, and the motor starts the heat dissipation fans at both ends of the housing to dissipate heat from the cable. When the temperature sensor detects that the temperature has returned to the normal temperature, the motor stops starting, causing the heat dissipation fans to stop.

[0020] In summary, the present invention has the following beneficial effects: 1. With the structure where the slider is slidably mounted on the top of the slide rail and the front and rear ends of the slider are fixedly connected to cords, the slider can be moved forward and backward by pulling the cords, enabling the cable to move to the corresponding position along with the slider. At the same time, it can reduce the wear when moving the cable. 2. With the structure where a spring is provided at the connection between the second clamping plate of the clamping device and the support column, the elastic deformation characteristic of the spring can form a buffer compensation mechanism, avoiding rigid extrusion caused by over-tightening by humans or vibration, and enhancing the compatibility and protection performance for cables of different specifications. 3. With the three-dimensional convection structure of the heat dissipation fins on the top of the housing, the ventilation holes on both sides, and the ventilation grooves at the inner bottom, it can cooperate with the linkage of the heat dissipation fan and the temperature sensor to achieve intelligent monitoring of the cable operating temperature and efficient heat dissipation, avoiding the risk of insulation aging caused by heat accumulation.

Under the action of the first spring 8, the mounting plate 43, the round rod 42 and the baffle 44 move upward. The ear plates 45 are fixedly connected to both ends of the mounting plate 43.

The motor 33 starts the heat dissipation fans 32 at both ends of the housing 1. Through the heat dissipation fans 32, the air flow inside is enhanced, so that the cold air entering the cable tray can flow along the inside of the cable tray, thereby dissipating the temperature of the cable. When the temperature sensor 31 detects that the temperature returns to the normal temperature, the motor 33 stops starting, so that the heat dissipation fans 32 stop.

9. A method for using a cable tray facilitating wire threading according to any one of claims 1-8, characterized in that, Including the following steps: Step S1: The cable passes through the buffer device (4) for preliminary positioning of the cable; Place the cable tray upright. Under the action of the first spring (8), the mounting plate (43), the round rod (42) and the baffle (44) move upward. The ear plates (45) are fixedly connected to both ends of the mounting plate (43). The cylinder (46) is rotatably mounted on the ear plates (45). Thus, the cylinder (46) moves upward, creating a gap between the cylinder (46) and the limit block (47). Pass the cable through the gap between the limit block (47) and the cylinder (46); Step S2: The cable penetrates into the clamping device (5) to fix the cable; After the cable passes through the buffer device (4), place the handle through the gap between the cable devices onto the nut (7). Rotate the nut (7) to drive the screw rod (6) to rotate, causing the screw rod (6) to move to the right, driving the first moving plate (51) to move to the right, thereby driving the support column (52) and the second moving plate (55) to move away from the first moving plate (51), creating a gap between the first clamping plate (53) and the second clamping plate (54). Pass the cable through the gap between the first clamping plate (53) and the second clamping plate (54). Then rotate the nut (7) through the handle to make the screw rod (6) move to the left, causing the second clamping plate (54) to move towards the position of the first clamping plate (53), so that the first clamping plate (53) and the second clamping plate (54) fix the cable; Step S4: Move the cable and pass the cable through the cable tray; Flip the cable tray 180°. The weight of the cable is all located at the center position of the cylinder (46). The first spring (8) moves the cylinder (46) upward to preliminarily clamp the cable. Then pull the cord at the rear of the slider (22) so that the slider (22) moves backward along the slide rail (21). When the slider (22) drives the clamping device (5) to move to the corresponding position, stop pulling the cord. The cable passes through the cable tray to complete the laying; Step S4: The temperature induction triggers the heat dissipation device (3) to start; When the temperature sensor (31) inside the housing (1) detects that the temperature of the cable exceeds a certain value, the signal of the temperature sensor (31) is transmitted to the motor (33). The motor (33) starts the heat dissipation fans (32) at both ends of the housing (1) to dissipate heat from the cable. When the temperature sensor (31) detects that the temperature returns to the normal temperature, the motor (33) stops starting, causing the heat dissipation fans (32) to stop.
