Description

Technical Field

[0001] This utility model relates to the field of cable tray trolley technology, and in particular to a cable tray trolley with steel rollers. Background Technology

[0002] In today's electrical engineering field, cable tray trolleys are widely used as an important cable transport tool. Traditional cable tray trolleys usually have a relatively simple structure and can meet the cable transport needs to a certain extent. However, with the rapid development of the power industry, the requirements for cable transport are also increasing.

[0003] After the existing cable tray trolley is installed, the nuts on both sides of the trolley frame are tightened or loosened according to the number and width of the cables to be passed, thereby changing the distance between the two sides of the frame and adjusting the overall width.

[0004] However, this adjustment method cannot adapt to the size of different types of cables. When multiple cables are transported at the same time, the cables are prone to getting tangled together, which reduces the transport efficiency and increases the workload of subsequent cable sorting and separation. It may even cause jamming and affect the normal construction progress. Utility Model Content

[0005] Given that the above adjustment methods cannot adapt to the size of different types of cables, and that when multiple cables are transported at the same time, the cables are prone to getting tangled together, resulting in reduced transport efficiency, increased workload for subsequent cable sorting and separation, and even jamming, affecting the normal construction progress, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to change the distance between two movable baffles in a single set by turning the fixing nut. When it is necessary to increase the distance between the baffles, the fixing nut is turned to increase the interval between some movable baffles, while the remaining movable baffles and the telescopic connecting parts connected to them are compressed to one side and can also be directly removed. At the same time, the movable baffles that fit together are connected by plug-in limiting parts, so as to adapt to the size of the corresponding cable model. When multiple cables are transported, the cables can move smoothly and smoothly, improving the work efficiency of workers.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a cable tray trolley with a steel roller, comprising a cable tray and a fixed connecting plate on one side of the cable tray, wherein the fixed connecting plate is provided with a plurality of limiting insertion slots, a rotating roller is provided between two fixed connecting plates, and a limiting fixing rod is provided at both ends of the rotating roller, one end of each limiting fixing rod is inserted into the inner side of the corresponding limiting insertion slot, and a connecting fixing member is provided on one side of the fixed connecting plate;

[0008] The partition assembly includes a constraint fixing rod installed between two connecting fixing members, and multiple movable baffles fixed on the constraint fixing rod. A telescopic connector is provided between every two movable baffles. A return spring is provided on the inner side of each telescopic connector. A plug-in limiting member is provided on one side of each movable baffle.

[0009] The fixing component includes a fixing constraint block installed on one side of the movable baffle and a fixing stud on one side of the fixing constraint block. The fixing constraint block is provided with multiple fixing nuts, and the fixing nuts are provided with positioning insertion slots. One end of each insertion limiting member is inserted into the inner side of the corresponding positioning insertion slot.

[0010] As a preferred embodiment of the cable tray trolley with steel rollers described in this utility model, a constraint fixing rod is provided between the two connecting fixing parts, two limiting constraint blocks are provided on the constraint fixing rod, and multiple movable baffles are provided between the two limiting constraint blocks.

[0011] As a preferred embodiment of the cable tray trolley with steel rollers described in this utility model, a telescopic connector is provided between every two movable baffles, a return spring is provided between every two movable baffles, each return spring is sleeved on a constraint fixing rod, an insertion constraint groove is opened on each movable baffle, and each constraint fixing rod is connected by inserting multiple insertion constraint grooves.

[0012] As a preferred embodiment of the cable tray trolley with steel rollers described in this utility model, wherein: an insertion limiting groove is provided on one side of each movable baffle, one end of a partial insertion limiting member is inserted into the inner side of the insertion limiting groove on the adjacent movable baffle, and a positioning constraint groove is provided on one side of each movable baffle, with one end of the rotating roller located inside the positioning constraint groove.

[0013] As a preferred embodiment of the cable tray trolley with steel rollers described in this utility model, the fixed constraint block is provided on one side of multiple movable baffles, one end of the fixed constraint block is provided with a fixed stud, the fixed stud is in contact with a movable baffle, and one side of the fixed stud is provided with an insertion constraint block.

[0014] As a preferred embodiment of the cable tray trolley with steel rollers described in this utility model, wherein: one end of the insertion constraint block is inserted into the inner side of the corresponding insertion limiting groove, and multiple fixing nuts are provided on the fixing constraint block, with internal threads opened on the inner wall of each fixing nut.

[0015] As a preferred embodiment of the cable tray trolley with steel rollers described in this utility model, each of the internal threads is connected to the fixed constraint block by threads, a positioning insertion groove is opened on the fixed nut, and some movable baffles are connected to multiple positioning insertion grooves by insertion limiting members.

[0016] The beneficial effects of this utility model are:

[0017] Tightening the fixing nut changes the distance between the two movable baffles in a single set. When it is necessary to increase the distance between the baffles, rotating the fixing nut makes the interval between some movable baffles larger, while the remaining movable baffles and the telescopic connectors connected to them are compressed to one side, or they can be directly removed. At the same time, the movable baffles that fit together are connected by plug-in limiting parts, so as to adapt to the size of the corresponding cable model. When multiple cables are transported at the same time, the cables can move smoothly and smoothly, improving the work efficiency of workers. Attached Figure Description

A positioning constraint groove 15 is provided on one side of each movable baffle 9. One end of the rotating roller 4 is located inside the positioning constraint groove 15.

[0031] Example 2

[0032] Reference Figure 3-6 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that it includes a fixed constraint block 20 installed on one side of the movable baffle 9, and a fixed stud 19 on one side of the fixed constraint block 20. The fixed constraint block 20 is provided with a plurality of fixed nuts 16, and the fixed nuts 16 are provided with positioning insertion grooves 17. One end of each insertion limiting member 13 is inserted into the inner side of the corresponding positioning insertion groove 17. The fixed constraint block 20 is located on one side of a plurality of movable baffles 9. One end of the fixed constraint block 20 is provided with a fixed stud 19, and the fixed stud 19 is in contact with a movable baffle 9.
