Description

Technical Field

[0001] This utility model relates to the field of cable traction technology, specifically a cable traction mechanism. Background Technology

[0002] A cable traction mechanism is a mechanical device used for laying, installing, or maintaining cables. A cable traction mechanism for laying cables, as described in patent document CN221777261U, uses a speed sensor to monitor the speed of a first belt assembly and a limit wheel. When the cable transport speed is lower than normal, the cable clamp drives a second belt assembly, increasing the pressure on the cable and thus increasing friction to facilitate cable transport.

[0003] The aforementioned technologies have the problem of not being able to change the cable angle. If the cable angle is inconsistent with the installation position, it will apply additional stress to the cable itself or the connector. Over time, this may lead to cable breakage or connector loosening. Forcibly bending or twisting the cable may cause the insulation layer to crack or be damaged, increasing the risk of short circuits and electric shock. Furthermore, the aforementioned technologies also have the problem of not being able to guide cables of different sizes. If they can only accommodate cables of a specific size, then cables outside that range will not be usable, causing compatibility issues. Attempting to cram an oversized cable into an undersized guiding system may damage the cable's insulation layer or even the conductors, causing safety hazards or performance degradation.

[0004] The purpose of this invention is to provide a cable pulling mechanism to solve the problem in the prior art that the cable angle cannot be changed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1.

The support plate 100 is equipped with a guiding assembly for guiding the cable. The bottom of the support plate 100 is equipped with an adjusting assembly for adjusting the support plate 100. By starting the first motor 503, it drives one of the first synchronous pulleys to rotate. Then, under the action of the first synchronous belt 504, it drives the other first synchronous pulley and the rotating roller 501 to rotate, thereby driving the conveyor belt 502 to rotate.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, the lifting assembly includes two sliders 601, which are respectively disposed at both ends of the second guide platform 400. Limiting blocks are provided at both ends of the second guide platform 400, and several limiting blocks and sliders 601 are slidably connected to the interiors of two fixed plates 200. Threaded rods 602 are rotatably connected inside the two fixed plates 200, and the two threaded rods 602 are threadedly connected to the interiors of the two sliders 601. A second motor 603 is provided at the top of one of the fixed plates 200, and the output end of the second motor 603... Each threaded rod 602 is connected to a corresponding threaded rod 602. A second synchronous pulley is provided on the end of each threaded rod 602 away from the second motor 603. A second synchronous belt 604 is provided between the two second synchronous pulleys. By starting the second motor 603, it drives one threaded rod 602 and the second synchronous pulley to rotate. Then, under the action of the second synchronous belt 604, it drives the other second synchronous pulley and the threaded rod 602 to rotate, thereby driving the slider 601 to rise and fall. Then, under the action of the limit block, it drives the second guide table 400 to rise and fall.

[0032] In one embodiment, such as Figure 1 and Figure 3As shown, the guiding assembly includes two support frames 701, which are respectively located at both ends of the top of the support plate 100. Slide plates 702 are slidably connected inside each of the two support frames 701. Bidirectional lead screws 703 are also rotatably connected inside the two support frames 701. The threads at both ends of the two bidirectional lead screws 703 are respectively threaded into the interior of several slide plates 702. Guide rollers 704 are provided on the top of several slide plates 702. By rotating the bidirectional lead screws 703, the slide plates 702 are moved closer or further apart.

[0033] In one embodiment, such as Figure 1 As shown, the adjustment assembly includes a base plate 801, one end of which is rotatably connected to the bottom of a support plate 100. A first electric push rod 802 is rotatably connected to both ends of the base plate 801. The output ends of the two first electric push rods 802 are respectively rotatably connected to the two ends of the support plate 100. A support assembly is provided around the base plate 801 to support the base plate 801. By activating the two first electric push rods 802, the support plate 100 is driven to rotate around one end of the base plate 801 as a base point.

[0034] In one embodiment, such as Figure 1 As shown, the support assembly includes a plurality of second electric push rods 901, which are respectively installed around the base plate 801. Each of the output ends of the second electric push rods 901 is provided with a support plate 902. By activating the second electric push rods 901, the support plate 902 is driven to rise and fall, thereby supporting the base plate 801.

[0035] In one embodiment, such as Figure 1 As shown, the bottom of the base plate 801 is equipped with casters on all four sides, which facilitates the movement of the base plate 801.

[0036] In one embodiment, such as Figure 1 As shown, the two first electric push rods 802 output at the same frequency to avoid interference when the support plate 100 rotates.

[0037] In one embodiment, such as Figure 3 As shown, a turntable is provided at one end of each of the two bidirectional lead screws 703 to facilitate the rotation of the bidirectional lead screw 703.

[0038] The above embodiment discloses a cable traction mechanism. By activating the second electric push rod 901, it drives the support plate 902 to above the caster wheel, and then moves it via the caster wheel. After moving to a suitable position, the second electric push rod 901 is activated again, causing the support plate 902 to move below the caster wheel, thereby supporting the base plate 801. Rotating the bidirectional lead screw 703 causes the sliding plates 702 to move closer or further apart, thereby adjusting the distance between the guide rollers 704 to accommodate cables of different sizes. After the cable passes through the guide rollers 704, the first motor 503 is activated, driving one first synchronous pulley to rotate. Then, under the action of the first synchronous belt 504, it drives another first synchronous pulley to rotate. The roller 501 rotates, thereby driving the conveyor belt 502 to rotate, thus pulling the cable. The second motor 603 can also be started, driving a threaded rod 602 and a second synchronous pulley to rotate. Then, under the action of the second synchronous belt 604, it drives another second synchronous pulley and threaded rod 602 to rotate, thereby driving the slider 601 to rise and fall. Then, under the action of the limit block, it drives the second guide platform 400 to rise and fall, thereby changing the height between the first guide platform 300 and the second guide platform 400, thereby increasing the friction of the cable and improving the traction. When adjustment is needed, the two first electric push rods 802 can be started, causing the support plate 100 to rotate around one end of the base plate 801 as a base point.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
