Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, and in particular to an incoming line frame and cable trolley. Background Technology
[0002] In existing technologies, cable trolleys, cable entry mechanisms, and walking systems (such as electric excavators) work together to use cables for power supply.
[0003] The shortcomings of existing technology: (1) Insufficient mobility: Since the cable trolley is an independent device, it needs to be transported separately when the excavator changes sites. However, its weight is basically over 2T and its volume is large, which makes it inconvenient to move in scenarios where site changes are frequent. (2) High site requirements: The placement site of the cable trolley needs to have flat and unobstructed ground conditions, and it is not very adaptable to complex or uneven terrain. (3) Insufficient equipment stability and safety: When the excavator moves within its working range, it will pull the cable, causing the cable trolley to swing with the cable, resulting in insufficient stability and safety of the trolley. Utility Model Content
[0004] The purpose of this utility model is to provide an incoming line frame and cable trolley to solve the technical problems of insufficient mobility of cable trolleys, high site requirements, and insufficient equipment stability and safety in the prior art.
[0005] To achieve the above objectives, the present invention provides a cable entry frame, including a lower sled base. The lower sled base includes two side beams distributed along the left and right sides, extending forward and backward. The front and rear ends of the side beams are provided with upwardly curved ends. A base frame is provided between the middle of the two side beams, and a crossbeam is provided between the ends at the left and right ends. An upper cable reel support is provided above the base frame. The upper cable reel support is connected to the base frame via a slewing bearing. The slewing bearing extends vertically along its axis. A cable reel and a distribution box are installed on the upper cable reel support. Upwardly extending columns are provided at the front and rear ends of the side beams. The columns are located between the crossbeams and the base frame. A connecting plate is provided between the tops of the columns at the left and right ends. The left and right ends of the connecting plate are respectively provided with lifting wheels that can move downwards.
[0006] Furthermore, several reinforcing structures are provided between the two side beams.
[0007] Furthermore, the two reinforcing structures are respectively located between the two side beams.
[0008] Furthermore, the reinforcing structure is a box structure, and the side beam is a circular tube.
[0009] Furthermore, the base frame and the crossbeam have a box-like structure.
[0010] Furthermore, the bottom of the lower sled base is provided with anti-wear blocks.
[0011] Furthermore, the lower sled base is provided with a detachable positioning pin, which can fix the upper cable reel bracket; the lower sled base is provided with a limiting block, which can limit the rotation angle of the upper cable reel bracket.
[0012] Furthermore, the crossbeam has two upward-protruding traction holes in the middle, the two traction holes are arranged along the left and right sides, and the crossbeam has hoisting holes at both the left and right ends.
[0013] Furthermore, the left and right ends of the two connecting plates are provided with a motor, a lifting mechanism, and a lifting wheel arranged sequentially downwards, and the motor controls the extension and retraction of the lifting wheel through the lifting mechanism.
[0014] This utility model also provides a cable trolley, including the cable entry frame described in any of the above technical solutions.
[0015] In summary, the application of the technical solution of this utility model has the following beneficial effects: The structure design of this utility model is reasonable. (1) By setting a lower sled base, the lower sled base includes two side beams distributed along the left and right sides. The side beams extend along the front and back. The front and back ends of the side beams are provided with upward arc-shaped bends. A base frame is set between the middle of the two side beams. A crossbeam is set between the ends of the left and right sides. An upper cable drum support is set above the base frame. The upper cable drum support is connected to the base frame through a slewing bearing. The axial direction of the slewing bearing extends vertically. A cable drum and a distribution box are installed on the upper cable drum support. Thus, the sled structure is used as a walking device, which is more convenient to walk on snow or soft ground than the existing cable trolley, and has stronger site adaptability. The sled base structure is similar to the excavator walking frame structure, which enhances stability. The lower sled base adopts two side beams, and multiple crossbeams are welded between the side beams. This special structural design makes the support have good strength and torsional stiffness. Meanwhile, the lower sled base is connected to the upper cable drum support by the slewing bearing, which can rotate freely and adapt to the cable direction, reducing the degree of cable damage; electrical components such as cable drums can be directly installed on the upper cable drum support. (2) By setting the front and rear ends of the side beam to have upward-extending columns, the columns are set between the crossbeam and the base frame, and the top of the columns at the left and right ends are set with connecting plates. The left and right ends of the connecting plates are respectively equipped with lifting wheels that can move downwards; thus, the lower sled base is equipped with lifting wheels that can move downwards. When on snow or soft ground, the lifting wheels are controlled to retract as a traditional sled, and the low friction characteristics are used for efficient gliding; in non-snow environments (soil, gravel, etc.), the lifting wheels are lowered to transform into a wheeled car, avoiding the wear and resistance caused by the sled directly contacting the rough ground, greatly expanding the application scenarios to all seasons. As can be seen from the above analysis, this utility model can achieve both wheeled and sled-type dual use. Attached Figure Description

[0019] See Figures 1 to 2This embodiment provides a line entry frame, including a lower sled base 1. The lower sled base 1 includes two side beams 101 distributed along the left and right sides. The side beams 101 extend forward and backward. The front and rear ends of the side beams 101 are provided with upwardly curved end 112. A base frame 102 is provided between the middle of the two side beams 101. A crossbeam 103 is provided between the end 112 at the left and right ends. An upper cable reel support 2 is provided above the base frame 102. The upper cable reel support 2 is connected to the base frame 102 through a slewing bearing 3. The slewing bearing 3 extends vertically along its axis. A cable reel and a distribution box are installed on the upper cable reel support 2. Upwardly extending columns 109 are provided at the front and rear ends of the side beams 101. The columns 109 are located between the crossbeam 103 and the base frame 102. A connecting plate 108 is provided between the tops of the columns 109 at the left and right ends. The left and right ends of the connecting plate 108 are respectively provided with lifting wheels 107 that can move downward. Functions: (1) By setting a lower sled base, the lower sled base includes two side beams distributed along the left and right sides. The side beams extend along the front and back. The front and back ends of the side beams are provided with upward arc-shaped bends. A base frame is set between the middle of the two side beams, and a crossbeam is set between the ends of the left and right sides. An upper cable reel support is set above the base frame. The upper cable reel support is connected to the base frame through a slewing bearing. The slewing bearing extends vertically along its axis. A cable reel and a distribution box are installed on the upper cable reel support. Thus, the sled structure is used as a walking device, which is more convenient to walk on snow or soft ground than the existing cable trolley, and has stronger site adaptability. The sled base structure is similar to the excavator walking frame structure, which enhances stability. The lower sled base uses two side beams, and multiple crossbeams are welded between the side beams. This special structural design makes the support have good strength and torsional stiffness. Meanwhile, the lower sled base is connected to the upper cable drum support by the slewing bearing, which can rotate freely and adapt to the cable direction, reducing the degree of cable damage; electrical components such as cable drums can be directly installed on the upper cable drum support. (2) By setting the front and rear ends of the side beam to have upward-extending columns, the columns are set between the crossbeam and the base frame, and the top of the columns at the left and right ends are set with connecting plates. The left and right ends of the connecting plates are respectively equipped with lifting wheels that can move downwards; thus, the lower sled base is equipped with lifting wheels that can move downwards. When on snow or soft ground, the lifting wheels are controlled to retract as a traditional sled, and the low friction characteristics are used for efficient gliding; in non-snow environments (soil, gravel, etc.), the lifting wheels are lowered to transform into a wheeled car, avoiding the wear and resistance caused by the sled directly contacting the rough ground, greatly expanding the application scenarios to all seasons. As can be seen from the above analysis, this utility model can achieve both wheeled and sled-type dual use.
[0020] Specifically, several reinforcing structures 104 are provided between the two side beams 101. Function: The special structural design, in which multiple crossbeams and reinforcing structures are welded between the side beams, gives the support good strength and torsional stiffness.
[0021] Specifically, the two reinforcing structures 104 are located between the two edge beams 101. Their function is to ensure a more balanced stress distribution between the edge beams.
[0022] Specifically, the reinforcing structure 104 is a box-shaped structure, and the side beam 101 is a circular tube. Function: This structural design gives the reinforcing structure 104 and the side beam 101 good strength and torsional stiffness.
[0023] Specifically, the base frame 102 and the crossbeam 103 have a box-like structure. Function: This structural design gives the base frame 102 and the crossbeam 103 good strength and torsional stiffness.
[0024] Specifically, the bottom of the lower sled base 1 is equipped with anti-abrasion blocks. Function: Adding anti-abrasion blocks to the bottom of the sled ensures the wear resistance of the bottom structure.
[0025] Specifically, the lower sled base 1 is equipped with a detachable positioning pin, which secures the upper cable reel bracket 2. The lower sled base 1 also has a limiting block, which restricts the rotation angle of the upper cable reel bracket 2. Functions: The detachable positioning pin allows the upper cable reel bracket 2 to rotate during transport by inserting it. The limiting block restricts the rotation angle of the upper cable reel bracket 2, ensuring it rotates only within a certain range and preventing excessive cable twisting that could damage the cable.
[0026] Specifically, the crossbeam 103 has two upward-protruding traction holes 105 in the middle, arranged horizontally. Lifting holes 106 are located at both ends of the crossbeam 103. Function: The two traction holes at the front of the lower sled base allow it to be attached to an excavator for towing. It can also be towed by pickup trucks, forklifts, loaders, etc. Four lifting holes are located above the lower sled base for easy hoisting.
[0027] As a preferred option, the lower sled base has pre-reserved installation positions for quick-change devices at the front and rear, allowing for selection of installation locations based on requirements.
[0028] Specifically, the two connecting plates 108 are equipped with a motor 110, a lifting mechanism 111, and lifting wheels 107 arranged sequentially downwards at their left and right ends. The motor 110 controls the extension and retraction of the lifting wheels 107 through the lifting mechanism 111. Function: On snow or soft ground, the motor controls the wheels (i.e., the lifting wheels) to retract, functioning as a traditional sled, utilizing low friction for efficient gliding. In non-snowy environments (soil, gravel, etc.), the wheels are lowered, transforming the sled into a wheeled vehicle, avoiding wear and resistance caused by direct contact between the sled and rough ground, significantly expanding its application to all seasons. The lifting mechanism allows for adjustment of ground clearance, protecting the chassis and maintaining stable movement when dealing with complex terrain (such as rocks and tree roots). The specific structure of the lifting mechanism can be selected according to actual needs and will not be elaborated here.
[0029] This utility model also provides a cable trolley, including the cable entry frame of any of the above-mentioned technical solutions. Function: When construction machinery (such as excavators) is operating on a construction site, it connects to the cable trolley via a cable. Specifically, the cable 4 on the cable entry frame enters the traveling frame 6 through the cable entry mechanism 5. When the traveling frame 6 serves as the traveling frame for an electric excavator, the front end of the cable entry mechanism 5 can be fixed to the rear end of the traveling frame 6, and the rear end of the cable entry mechanism 5 engages with the cable 4 on the cable entry frame for traction. This utility model is applicable to towed electric excavators. The cable entry frame can be placed on the side of the excavator, without obstructing trucks from loading directly behind the excavator.
[0030] In summary, this utility model is equipped with four lifting wheels, enabling it to function as both a wheeled and sled vehicle, adapting to various terrains; it enhances maneuverability, making it easy to move on both snow and hard ground; the extension and retraction of the wheels is achieved through a motor, making storage and conversion mechanisms convenient and improving the user experience.
[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
