Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to an auxiliary device for cable laying at turning angles. Background Technology

[0002] Cable laying is a common part of electromechanical construction, and cables are often laid in complex environments such as cable trays and cable trenches, with relatively tortuous cable routes.

[0003] At present, cable laying, especially the laying of larger cables, is basically carried out by using winches in conjunction with pulleys. Pulleys are usually fixed by welding, binding, expansion bolts, or simple placement. Top support pulleys and guide pulleys are basically fixed individually.

[0004] The use of expansion bolts for fixing and welding makes it relatively difficult to adjust the position during construction and dismantle later, and it is also easy to damage the cable tray or concrete structure. Simple placement can easily cause pulleys to move, and cables can be damaged if not supervised in time. Moreover, because the fixing methods are inherently unstable, each bend requires dedicated personnel to monitor, and the laying of a long cable often requires a large number of people to monitor. In addition, indoor horizontal cable trays are often located on the roof and are arranged in layers, making it relatively difficult to manually assist cables through bends.

[0005] Therefore, to address the challenges of rapid deployment and easy adjustment of cable laying bend-crossing devices, thereby freeing up manpower, an integrated cable bend-crossing device is proposed to assist in cable laying work and improve construction efficiency. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary device for cable laying at bends, which can be quickly set up and disassembled, assisting cables in passing bends and improving the efficiency of cable laying.

[0007] To solve the above problems, this utility model provides an auxiliary device for cable laying at turning angles, including a support adjustment mechanism and a cable guiding mechanism;

[0008] The support adjustment mechanism includes a telescopic adjustment body, a fixed support body, and a slip ring. The telescopic adjustment body is connected to the fixed support body. By adjusting the length of the telescopic adjustment body, the two ends of the support adjustment mechanism are supported at the cable laying position. The slip ring is set on the periphery of the fixed support body to support and protect the cable.

[0009] The cable guiding mechanism includes a pulley and a pulley support frame. The pulley is mounted on the pulley support frame, and a channel for the cable to pass through is formed inside the pulley support frame. The pulley support frame is provided with a movable door, which has an open and a closed state. In the open state, the cable can be placed into the channel. The pulley support frame is connected to a fixed support body.

[0010] Adjust the support structure according to the width of the cable trench or cable tray so that it supports the two side walls of the cable trench or cable tray for quick installation. To disassemble, simply retract the telescopic adjustment body. The upper surface of the slip ring is at approximately the same height as the lower part of the pulley. When laying the cable, the slip ring supports the cable and rolls, which plays a role in supporting and preventing hard friction of the cable. The cable is guided through bends by the action of the pulley.

[0011] According to one embodiment of the present invention, the telescopic adjustment body includes a support screw, an adjusting nut, and a replaceable support rod. The adjusting nut is installed on the support screw, the support screw can be retracted into the replaceable support rod, and the replaceable support rod is detachably connected to the fixed support body.

[0012] Replaceable struts of different lengths can be used depending on the actual application scenario.

[0013] According to one embodiment of the present invention, the cable guiding mechanism is provided with at least two sets. The double pulley arrangement can avoid the bending radius being too small when laying the cable, and at the same time facilitates its use in various positive and negative angle structures.

[0014] According to one embodiment of the present invention, a tubular support is installed on the fixed support body, and the replaceable support rod is installed in the support, which facilitates the positioning and installation of the replaceable support rod.

[0015] According to one embodiment of the present invention, the end of the supporting screw is connected to a first supporting seat, and the end of the fixed support body is connected to a second supporting seat, thereby increasing the contact area and ensuring stable support.

[0016] According to one embodiment of the present invention, the pulley support frame is mounted on the second support base.

[0017] According to one embodiment of the present invention, the pulley support frame includes support plates located on both sides of the pulley. The upper support plate is divided into two sections and connected by hinges to form a movable door.

[0018] According to one embodiment of the present invention, two sets of cable guiding mechanisms are respectively arranged on both sides of the fixed support, and the slip ring is located between the two sets of pulleys.

[0019] According to one embodiment of the present invention, the fixed support, slip ring, and replaceable strut are all steel pipes.

[0020] According to one embodiment of the present invention, the supporting screw is a hollow supporting screw, which reduces weight.

[0021] The beneficial effects of this utility model are that, through the setting of the support adjustment mechanism and the cable guiding mechanism, the structure is small in size and easy to carry. When laying cables through bends, the length of the support adjustment structure can be adjusted according to the width of the cable trench or cable tray, so that it supports the two side walls of the cable trench or cable tray, achieving rapid deployment. When disassembling, the telescopic adjustment body can be retracted to disassemble, achieving rapid disassembly, thereby improving the efficiency of cable laying through bends and reducing the reliance on manpower. When laying cables, the slip ring supports the cable and rolls, playing a supporting role and avoiding hard friction of the cable. The cable is guided through bends under the action of the pulley, and the double pulley structure can be used for cable laying at different angles and directions. Attached Figure Description
