This device greatly improves the installation efficiency and quality of electromechanical engineering projects. It can effectively reduce on-site construction difficulty and labor costs, and improve construction efficiency and safety.

[0003] After searching, the patent document with the announcement number "CN216819270U" discloses a cable installation device for building electromechanical installation, comprising a housing; a wire tube is provided at the lower end of the interior of the housing, and both ends of the wire tube are connected to the two side walls of the housing through a tapered tube, and a through-hole is opened in the side wall of the wire tube. A holding assembly is provided inside the housing just above the wire tube. The holding assembly includes a plurality of adjustment rods arranged at intervals and rotatably installed inside the housing. The bottoms of the plurality of adjustment rods are all provided with a pressure rod obliquely installed, and the tops of the plurality of adjustment rods are hinged to a driving rod. A pull rod is installed at one end of the driving rod, and the pull rod passes through the side wall of the housing and is slidably connected to the housing. This cable installation device for building electromechanical installation facilitates workers in dragging cables, avoids injuries to workers when dragging cables, and improves the efficiency of cable installation.

[0004] Based on the above search and in combination with the prior art, it is found that the existing cable laying devices for electromechanical installation are limited by the single operation volume of manual operations, resulting in a limited single cable transmission length when using the existing cable laying devices for electromechanical installation. During the cable laying process, the length of the cable that needs to be pulled is usually long, especially in some high-rise buildings or long passages (such as coal mines and tunnel construction) where the construction volume is particularly large, resulting in high work intensity for workers and low construction efficiency. Therefore, a cable laying device for electromechanical installation is needed. Utility Model Content

The transmission ratio between the driving member and the driving shaft is less than 1.

[0008] A driven wheel is also rotatably connected inside the shell. The lower end of the driven wheel cooperates with the driving wheel to clamp the cable.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example: Reference Figures 1-4 The cable laying device for electromechanical installation shown in the figure comprises a housing 1 with wire threading openings 11 at both ends and a driving wheel 2 rotatably connected to the housing 1 via a driving shaft 21;

[0029] One side of the housing 1 is rotatably connected to a driving member 4 (the driving member in this embodiment is a rotating wheel with a handle, see Figure 1 , other driving parts can also be used as power parts, such as servo motors), the housing 1 is further provided with an acceleration gear set 5 on the side corresponding to the driving part 4, and the acceleration gear set 5 adopts a gear set commonly used in the prior art and suitable for this embodiment, which is composed of large and small gears meshing with each other and coaxially transmitting (this is the prior art, which can be referred to Figure 1 ), the input end gear of the acceleration gear set 5 is fixedly sleeved on the rotating shaft of the driving member 4, and the output end gear of the acceleration gear set 5 is fixedly sleeved on the driving shaft 21, and the transmission ratio between the driving member 4 and the driving shaft 21 is less than 1 (that is, the driving member 4 rotates 1 circle, and the driving shaft 21 rotates multiple circles, which can be specifically set to be 10 circles or more);

[0030] A driven wheel 3 is also rotatably connected inside the housing 1. The lower end of the driven wheel 3 cooperates with the driving wheel 2 to clamp the cable. A ratchet structure 7 fixed to the other end of the driving shaft 21 is installed on the back side of the housing 1. The ratchet structure 7 is a prior art and will not be elaborated here. The ratchet structure 7 is used to limit the driving shaft 21 so that it cannot rotate in the opposite direction.

[0031] Based on the above structure, after the worker passes the cable through the threading port 11 at one end into the housing 1 and passes it between the driving wheel 2 and the driven wheel 3 and then out of the threading port 11 at the other end, he can rotate the driving member 4 to drive the acceleration gear set 5 to transmit, and finally drive the driving shaft 21 to accelerate, so that the driving wheel 2 actively rotates to drive the cable to move. Due to the setting of the acceleration gear set 5, the work done by one rotation of the driving member 4 can drive the driving wheel 2 to rotate multiple times, thereby increasing the efficiency of a single work, being able to pull the cable for a longer distance, improving the efficiency of cable installation, and improving construction efficiency;

[0032] In addition, the provision of the ratchet structure 7 can prevent the driving wheel 2 from rotating in the opposite direction, thereby reducing the probability of the cable retracting when not subjected to traction, and improving the stability and reliability of the cable during installation.

[0033] Furthermore, a sliding hole 12 is formed on a side of the housing 1 away from the driving member 4, and a driven shaft 31 is rotatably inserted into the middle of the driven wheel 3, and one end of the driven shaft 31 rotates through the sliding hole 12 and slides up and down along the sliding hole 12;

[0034] A slide rail 14 is fixed to the inner wall of the housing 1 away from the positioning side plate 8, and the other end of the driven shaft 31 is movably inserted into the slide rail 14;

[0035] A limiting member is also installed on the side of the driving wheel 2 corresponding to the sliding hole 12, and the limiting member is used to fix the driven shaft 31;

[0036] The limiting member includes a positioning side plate 8 with a second positioning hole 81 formed thereon. The driven shaft 31 is provided with a first positioning hole 311 corresponding to the second positioning hole 81 . A positioning bolt 82 penetrates both the second positioning hole 81 and the first positioning hole 311 .

[0037] By setting the slide hole 12 and the slide rail 14, the height of the driven wheel 3 can be adjusted, thereby being able to adjust the distance between the lower end of the driven wheel 3 and the upper end of the driving wheel 2, so as to adapt to the use of cables with different diameters within a certain range, thereby expanding the scope of use of the cable laying device for electromechanical installation;

[0038] Before and after adjustment, the driven shaft 31 is fixed and limited by inserting the positioning bolt 82 into the second positioning hole 81 and the first positioning hole 311, thereby fixing the position of the driven wheel 3 and ensuring stability when clamping the cable.

[0039] Furthermore, support wheels 6 are installed at both ends of the housing 1. The end of the rotating shaft of the support wheel 6 is rotatably sleeved with a support frame 61. A compression spring 62 is fixed to the lower end of the support frame 61. The lower end of the compression spring 62 is fixed to the bottom wall of the housing 1.

[0040] A sliding groove 15 is formed on the inner side wall of the housing 1 , and a slider 63 is fixed to the side wall of the support frame 61 . The slider 63 is slidably embedded in the sliding groove 15 .

[0041] By setting the support wheels 6 on both sides, the cables can be assisted to be supported at both ends of the driving wheel 2 and the driven wheel 3, thereby avoiding the cables being bent too much at that location and being difficult to move, ensuring smooth cable installation and reducing installation difficulty.

[0042] Furthermore, the surface of the driving wheel 2 in contact with the cable is provided with a first anti-slip groove 22, and the surface of the driven wheel 3 in contact with the cable is provided with a second anti-slip groove 32. The width of the driven wheel 3 is smaller than the width of the driving wheel 2, and the lower end of the driven wheel 3 can extend into the groove of the driving wheel 2 for clamping the cable. The provision of the first anti-slip groove 22 and the second anti-slip groove 32 can enhance the stability of cable clamping, and can better fix the cable in combination with the ratchet structure 7.

[0043] Furthermore, a dust collecting hole 13 is provided at the bottom of the outer shell 1, which can make it easier to discharge the dust that enters the outer shell 1, and prevent the dust from accumulating in the outer shell 1 and affecting the use of the device. A protective shell 9 is fixed to one side of the outer shell 1, and the protective shell 9 is covered on the outside of the acceleration gear set 5. The middle part of the rotating shaft of the slide rail 14 rotates through the acceleration gear set 5.

[0044] Working principle of the present utility model: During daily use, the staff first passes the cable into the outer casing 1 from the threading port 11 at one end, and passes it through the top of the support wheel 6, between the driving wheel 2 and the driven wheel 3, and the top of the other support wheel 6 in turn, and then passes it out from the threading port 11 at the other end. After that, the driving member 4 can be rotated to drive the acceleration gear set 5 to transmit, and finally drive the driving shaft 21 to accelerate, so that the driving wheel 2 actively rotates to drive the cable to move. Due to the setting of the acceleration gear set 5, the work done by one rotation of the driving member 4 can drive the driving wheel 2 to rotate multiple circles, thereby increasing the efficiency of a single work, being able to pull the cable for a longer distance, improving the cable installation efficiency, and improving the construction efficiency.

The specific structures, working principles and possible control methods and spatial layout methods of these technical features can be selected according to conventional methods in the field and should not be regarded as the inventive points of this utility model patent. This utility model patent will not be further elaborated.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
