Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a cable laying pulley. Background Technology

[0002] To facilitate the loading and unloading of cables in the enclosed space, existing cable-laying trolleys often feature flip-up cover assemblies that can open the enclosed space. However, these cover assemblies are mostly locked in place by threaded parts when closed, requiring multiple turns of screwing to loosen or loosen the threads when closing or opening them, making operation cumbersome. Furthermore, after the cover assemblies are loosened and unlocked, additional manual force is required to flip them open, further exacerbating the operational difficulties of the cable-laying trolley.

[0007] A cover plate is disposed at the cable inlet; the cover plate is movably connected to the pulley frame, and the cover plate can move relative to the pulley frame along a first movement path; the cover plate is used to open or close the cable inlet; the cover plate is provided with a first locking part;

[0008] A cover ejector, which is an elastic member, is used to drive the cover body away from the pulley frame so as to open the cable insertion port;

[0009] A locking component is slidably connected to the pulley frame. The locking component has a second locking part, which is arranged along a first movement path with the first locking part. The locking component has a first position and a second position. In the first position, the second locking part abuts against the first locking part, and the second locking part limits the cover plate. In the second position, the second locking part disengages from the first locking part.

[0010] A locking reset component, wherein the locking reset component drives the locking component to reset from the second position to the first position;

[0011] A control pressing component is provided on the pulley frame. The control pressing component is linked with the locking component. When the control pressing component is pressed, the locking component moves from the first position to the second position.

[0012] As a further improvement to the above technical solution, the locking member is provided with an insertion guide portion, which is disposed opposite to the first locking portion; during the closing process of the cover plate, the insertion guide portion abuts against the cover plate, and the insertion guide portion pushes the locking member to move away from the cover plate.

[0013] As a further improvement to the above technical solution, a hook is installed at the upper end of the pulley frame.

[0014] As a further improvement to the above technical solution, the hook is rotatably connected to the pulley frame.

[0015] As a further improvement to the above technical solution, both the locking reset component and the cover plate ejector are springs.

[0016] As a further improvement to the above technical solution, it also includes:

[0017] A pulley shaft, which is mounted on the pulley frame;

[0018] A pulley body, which is rotatably connected to the pulley shaft, and the pulley body and the pulley shaft are detachably connected.

[0019] As a further improvement to the above technical solution, the pulley body includes:

[0023] The cylinder is provided in two, and the two cylinders are slidably connected; the ends of the cylinders that are far apart from each other are designated as insertion ends, and the insertion ends are inserted into the pulley frame.

[0024] A wheel axle elastic element is connected to the two cylinders, and the wheel axle elastic element causes the two cylinders to tend to move away from each other.

[0025] As a further improvement to the above technical solution, the cylinder is provided with a limiting member for restricting the position of the pulley body.

[0026] As a further improvement to the above technical solution, the limiting member is detachably connected to the cylinder.

[0027] The beneficial effects of this utility model are: in the first position, the second locking part abuts against the first locking part, and the second locking part limits the first locking part, thereby preventing the cover plate from moving along the first movement path.

[0028] When the press control terminal is pressed, the locking control terminal is lifted, thereby driving the locking member to move from the first position to the second position to unlock the cover. In the second position, the second locking part disengages from the first locking part, and the first locking part moves away from the pulley frame due to the force of the cover ejector. The cover moves relative to the pulley frame, opening the cable insertion port.

[0029] By pressing the locking mechanism, the locking element can be moved from the first position to the second position, which avoids the need for staff to manually pull the locking element from the first position to the second position, making the unlocking of the cover plate easier.

[0036] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0037] Reference Figures 1 to 3 A cable laying trolley has a first direction, a second direction and a third direction, which are perpendicular to each other. The second direction is parallel to the Y-axis in the figure, and the third direction is parallel to the Z-axis in the figure.

[0038] The cable laying trolley includes a pulley frame 100, a cover plate body 200, a cover plate ejector 300, a locking component 400, a locking reset component 500, a control pressing component 600, a pulley shaft 700, and a pulley body 800.

[0039] The pulley frame 100 is provided with a cable inlet located at the upper end of the pulley frame 100. The pulley frame 100 has a rectangular frame structure, with the inner side of the rectangular frame structure configured as the cable mounting side, through which the cable passes in a first direction.

[0040] A hook 110 is installed at the upper end of the pulley frame 100. The hook 110 is rotatably connected to the pulley frame 100, and the axis of rotation of the hook 110 is set parallel to the second direction.

[0041] A cover plate 200 is disposed at the cable inlet. The cover plate 200 is movably connected to the pulley frame 100, and the cover plate 200 can move relative to the pulley frame 100 along a first motion path. Specifically, in this embodiment, the cover plate 200 is hinged to the pulley frame 100, and the cover plate 200 rotates about an axis parallel to a first direction. The first motion path is an arc path, and the first motion path is parallel to the YZ plane.

[0042] In other embodiments, the hinge axis between the cover plate 200 and the pulley frame 100 may be set to be parallel to the second direction, and the first motion path may be set to be parallel to the plane formed by XZ.

[0043] In other embodiments, the cover plate 200 may be configured to slide and connect with the pulley frame 100, with the first movement path parallel to the second direction.

[0044] Those skilled in the art can select the specific connection method and movement path of the cover plate 200 and the pulley frame 100 according to actual needs.

[0045] The cover plate 200 is provided with a first locking part 210, which is located at the end of the cover plate 200 away from the hinge point with the pulley frame 100.

[0046] A cover ejector 300 is disposed between the pulley frame 100 and the cover body 200. The cover ejector 300 drives the cover body 200 to move relative to the pulley frame 100, thereby opening the cable insertion port. Specifically, in this embodiment, the cover ejector 300 is disposed between the pulley frame 100 and the first locking part 210. The cover ejector 300 is configured as a spring, with one end fixedly connected to the first locking part 210 and the other end abutting against the pulley frame 100. When the cover body 200 closes the cable insertion port, the first locking part 210 abuts against the cover ejector 300, compressing the cover ejector 300 and accumulating elastic potential energy. After other external forces acting on the cover body 200 disappear, the cover ejector 300 recovers its deformation, causing the cover body 200 to automatically move along the first movement path, thereby automatically opening the cable insertion port and making it more convenient for operators to operate.

[0047] In other embodiments, the cover ejector 300 may also be configured as a torsion spring. When configured as a torsion spring, the cover ejector 300 is positioned at the hinge between the cover body 200 and the pulley frame 100. In other embodiments, the cover ejector 300 may also be configured as other elastic components. Those skilled in the art can select the specific structure of the cover ejector 300 according to actual needs.

[0048] The locking member 400 is slidably connected to the sliding frame. Specifically, in this embodiment, the locking member 400 can slide relative to the sliding frame in a second direction. In other embodiments, the locking member 400 can also slide relative to the sliding frame in a first direction. Those skilled in the art can select the sliding direction of the locking member 400 according to actual needs.

[0049] The locking member 400 is provided with a second locking part 410. The second locking part 410 and the first locking part 210 are arranged along the first movement path. In this embodiment, the second locking part 410 is located on the side of the first locking part 210 away from the cable installation side. The second locking part 410 is used to restrict the position of the first locking part 210, thereby restricting the movement of the first locking part 210 along the first movement path.

[0050] The locking member 400 is provided with a first position and a second position. The first position and the second position are arranged along a second direction. In the first position, the second locking part 410 abuts against the first locking part 210, and the second locking part 410 limits the first locking part 210, thereby preventing the cover plate 200 from moving along the first movement path. In the second position, the second locking part 410 disengages from the first locking part 210, and the first locking part 210 moves away from the pulley frame 100 due to the force of the cover plate ejector 300. The cover plate 200 moves relative to the pulley frame 100, opening the cable insertion port.

[0051] A locking reset member 500 is disposed between the locking member 400 and the pulley frame 100. The locking reset member 500 is a spring, with its two ends abutting against the locking member 400 and the pulley frame 100, respectively. When the locking member 400 moves from the first position to the second position, the locking reset member 500 accumulates elastic potential energy. When other external forces acting on the locking member 400 disappear, the locking reset member 500 restores its deformation, causing the locking member 400 to automatically move from the second position to the first position. In other embodiments, the locking reset member 500 may also be configured as other elastic components. Those skilled in the art can select the specific structure of the locking reset member 500 according to actual needs.

[0052] Specifically, in this embodiment, the locking member 400 is provided with an insertion guide portion 420, which has an inclined guide surface. The insertion guide portion 420 is disposed opposite to the first locking portion 210. During the closing process of the cover plate 200, the inclined guide surface of the insertion guide portion 420 abuts against the cover plate 200, and the insertion guide portion 420 pushes the locking member 400 to move away from the cover plate 200, so that the cover plate 200 can be closed smoothly. This avoids the trouble of manually operating the locking member 400 to move the cover plate 200, thereby effectively improving work efficiency.

[0053] A control press is located on one side of the locking member 400 and is slidably connected to the pulley frame 100. The control press and the locking member 400 are connected by a linkage 610. Specifically, the linkage 610 is a rod-shaped component, with its middle section rotatably connected to the pulley frame 100. The two ends of the linkage 610 are respectively designated as a press control end 611 and a locking control end 612. The press control end 611 abuts against the control press, and the locking control end 612 abuts against the locking member 400. When the press control end 611 is pressed, the locking control end 612 is lifted, thereby driving the locking member 400 to move from a first position to a second position, thus unlocking the cover plate 200. By pressing the locking element 400, the locking element 400 can be moved from the first position to the second position, which avoids the need for the operator to manually pull the locking element 400 from the first position to the second position, making the unlocking operation of the cover body 200 simpler.

[0054] The pulley shaft 700 is detachably connected to the pulley frame 100. Specifically, in this embodiment, the pulley shaft 700 includes a cylindrical body 710 and a wheel axle elastic element 720. The cylindrical body 710 has an overall cylindrical structure, and there are two cylindrical bodies 710. The two cylindrical bodies 710 are slidably connected, and the outer diameter of one cylindrical body 710 is smaller than the inner diameter of the other cylindrical body 710. The larger cylindrical body 710 is fitted onto the smaller cylindrical body 710. The ends of the two cylindrical bodies 710 that are far apart from each other are designated as insertion ends, which are inserted into the pulley frame 100.

[0055] A wheel axle elastic element 720 is disposed between the two cylinders 710. In this embodiment, the wheel axle elastic element 720 is configured as a spring structure. In other embodiments, the wheel axle elastic element 720 may be configured as other elastic structures. Those skilled in the art can select the specific structure of the wheel axle elastic element 720 according to actual needs. The two ends of the wheel axle elastic element 720 abut against the two cylinders 710 respectively. When the two cylinders 710 approach each other, the wheel axle elastic element 720 is compressed, and the wheel axle elastic element 720 accumulates elastic potential energy, shortening the length of the pulley axle 700. When the external force applied to the two cylinders 710 disappears, the wheel axle elastic element 720 recovers its deformation, driving the two cylinders 710 away from each other, so that the length of the pulley axle 700 returns to its original value.

[0056] The overall length of the pulley shaft 700 can be adjusted by the two cylinders 710. When it is necessary to install the pulley shaft 700 onto the pulley frame 100 or remove it from the pulley frame 100, the length of the pulley shaft 700 is shortened first, and then the pulley shaft 700 can be installed or removed.

[0057] The pulley body 800 is rotatably mounted on the pulley shaft 700. Specifically, in this embodiment, the pulley body 800 includes a limiting wheel body 820 and a main wheel body 810. Two limiting wheels 820 are provided, and the two limiting wheels 820 are arranged at intervals along the axis of the pulley body 800. The main wheel body 810 is disposed between the two limiting wheels 820, and the main wheel body 810 is fixedly connected to the limiting wheels 820. The outer diameter of the main wheel body 810 is smaller than the outer diameter of the limiting wheels 820. Specifically, in this embodiment, the limiting wheel body 820 has a frustum-shaped structure, and its diameter gradually decreases from the direction away from the main wheel body 810 towards the main wheel body 810.

[0058] By setting the limiting wheel 820, the cable can be held at the main wheel 810 to prevent the cable from accidentally contacting the pulley frame 100 and causing friction, thereby avoiding cable wear. Furthermore, the limiting wheel 820 is designed as a frustum-shaped structure to accommodate cables of different diameters.

[0059] Specifically, in this embodiment, the cylinder 710 is provided with a limiting member 730 for limiting the position of the pulley body 800. The limiting member 730 is a sheet-like component, and the limiting member 730 is detachably connected to the cylinder 710 by means of plug-in connection.

[0060] After prolonged use, the pulley body 800 of this cable laying trolley may be damaged. When the pulley body 800 is damaged, the operator can remove the pulley shaft 700 and the pulley body 800 from the pulley frame 100, replace the pulley body 800 with a new one, and reinstall the new pulley body 800 and the pulley shaft 700 back into the pulley frame 100 so that the cable laying trolley can continue to work.

[0061] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
