Description

Technical Field

[0001] This utility model belongs to the field of cable construction technology, and specifically relates to a cable tray conveying support frame. Background Technology

[0002] In the process of modern urban construction, both industrial and residential buildings require the installation of cable trays to lay numerous essential electrical wires and cables. Cable trays are particularly prevalent in the telecommunications, petroleum, power, light industry, and chemical industries. The primary function of cable trays is to enclose the conductors, achieving an aesthetically pleasing appearance while also providing fire resistance.

[0003] Currently, the following defects exist in the cable laying process: when laying multiple cables, they generally come out directly from the roller. When the cables enter the cable tray from the bottom, they are prone to mutual squeezing and twisting; when the cable turns a corner, the armor is easily flattened, causing cable damage. Utility Model Content

[0004] In view of the problems mentioned in the prior art, this utility model provides a cable tray conveyor support frame, which can avoid the occurrence of the above problems.

[0005] This utility model is achieved through the following measures: a cable tray conveying support frame, characterized in that it includes a mounting frame, a guide box is provided on one side of the mounting frame, a rotating frame is provided on the other side of the guide box, the mounting frame includes two parallel mounting beams, a plurality of rotating shafts are provided between the two mounting beams, and conveying rollers are mounted on the rotating shafts;

[0006] The rotating frame includes a first base plate, on which vertical plates are symmetrically arranged, and a first rotating shaft is provided between the two vertical plates. A winding wheel is installed on the first rotating shaft.

[0007] The guide box includes a second base plate with side plates on both sides. The second base plate has several expandable / telescopic bags. A rope inlet is located on one side of the base plate, and the rope inlet has several partitions. Guide shafts are located at both ends of the rope inlet and the partitions, and guide wheels are mounted on the guide shafts. The guide shafts on the same partition are located on different sides of the partition. The guide wheels prevent the cable from being easily flattened by the armor when turning corners, thus avoiding cable damage. The rope inlet is generally a trapezoidal opening with outward expansion. The rope inlet generally faces the mounting frame.

[0008] The mounting frame is connected to a cable tray via connecting components. Each connecting component includes a connecting plate, one end of which is connected to the mounting frame and the other end to a vertical plate. A horizontal plate is fixedly connected to the upper end of the vertical plate. A slider is slidably fitted onto the vertical plate, and a lower clamping plate parallel to the horizontal plate is fixedly connected to the slider. The cable tray is held between the lower clamping plate and the horizontal plate. The connecting plate is typically connected to the mounting frame and the vertical plate using bolts.

[0009] Furthermore, a screw is provided on the lower clamping plate via a threaded connection, and a threaded hole is provided on the horizontal plate to mate with the screw.

[0010] Furthermore, a support mechanism is provided on the lower side of the mounting frame. The support mechanism includes fixed plates disposed at both ends of the mounting beam, and support legs are provided below the fixed plates by bolts.

[0011] The legs closer to the cable tray are higher than the legs farther away from the cable tray.

[0012] Furthermore, each of the two vertical plates is provided with a guide groove, and a guide block is slidably fitted within the guide groove. The guide block is connected to an upper mounting block and a lower mounting block. The upper mounting block is connected to a telescopic spring, and the telescopic spring is connected to a fixing block. The fixing block is mounted on the top of the vertical plate. A cam is rotatably connected to the vertical plate, and the rotation of the cam allows the guide block to move along the guide groove. A brake band is provided between the two guide blocks, and the brake band restricts the rotation of the winding wheel. A telescopic guide rod is provided inside the telescopic spring. The telescopic guide rod includes an outer rod and an inner rod. The upper end of the outer rod is fixed to the fixing block, and the lower end of the inner rod is fixed to the upper mounting block. The upper end of the inner rod is sleeved on the outer rod, and a circular hole is provided inside the outer rod to mate with the inner rod.

[0013] Furthermore, each of the mounting beams is equipped with a protective plate.

[0014] Furthermore, the protective plate is provided with a mounting groove, a slider is slidably fitted in the mounting groove, a pressure roller spring is provided between the slider and the mounting groove, an auxiliary shaft is provided on the slider, an upper pressure roller is provided on the auxiliary shaft, and the cable is located between the upper pressure roller and the transmission roller.

[0015] Furthermore, the upper pressure roller includes a pressure roller body, and the pressure roller body is provided with a guide ring groove that is low in the middle and high at both ends.

[0016] Furthermore, the top of the vertical plate is provided with an installation shaft, and a guide roller is connected to the installation shaft.

[0017] Furthermore, a second rotating shaft rotates on the vertical plate, and a cam is connected to the second rotating shaft. A handle is fixedly installed on the cam.

[0018] Furthermore, at least one of the legs can be in the form of a telescopic rod, which allows for adjustment of the mounting bracket angle according to actual conditions.

[0019] Furthermore, the support legs can be fixedly connected to the mounting frame with bolts, allowing the support legs to be stored and facilitating the overall handling of the support frame.

[0020] Furthermore, inflatable and telescopic bags generally adopt a corrugated tube shape supported by air bladders.

[0021] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: This utility model effectively avoids damage to cables during cable laying. The protective plate prevents the cable from slipping off both sides; the design of the mounting groove, slider, pressure roller spring, and upper pressure roller prevents the cable from warping during pulling. The guide groove design facilitates keeping the cable at the center of the pressure roller body during cable pulling. The connecting component design makes the connection between the support frame and the cable tray more stable and convenient. The guide roller design facilitates the guidance of the cable from the support frame to the cable tray. Attached Figure Description
