Description

Technical Field

[0001] This utility model relates to the field of current collector technology, specifically to a sliding contact line current collector. Background Technology

[0002] A sliding contact line current collector is a current collector that works with a sliding contact line to supply power to mobile equipment. It is used on mobile equipment such as monorail mobile hoists and electric hoists. A common installation structure can be found in the electric hoist sliding contact line power supply structure described in Chinese utility model patent document CN210150605U. The electric hoist is installed on a running trolley, which is moved on a track. The sliding contact line is fixedly installed on the track parallel to it. The current collector is fixedly installed on the running trolley by its fixing rod. The contact body of the current collector is slidably connected to the sliding contact line so that the sliding contact line supplies power to the current collector during the sliding of the running trolley. The current collector is electrically connected to the travel motor and lifting motor of the electric hoist through cables to supply power to the travel motor and lifting motor.

[0003] The current collector is connected to the mobile device via a fixed rod. When the mobile device moves, the fixed rod drives the current collector to move along the sliding contact line. However, this fixed connection structure between the current collector and the mobile device is susceptible to problems in applications with long sliding contact lines. These problems can be caused by factors such as bending and deformation of the sliding contact line, as well as vertical distance deviations between the mobile device and the sliding contact line, leading to poor contact or obstruction between the current collector and the sliding contact line. Utility Model Content

[0004] The purpose of this utility model is to provide a sliding contact line current collector to solve the problems of poor contact or sliding jamming that are common in current sliding contact line current collectors.

[0005] The technical solution of this utility model's sliding contact line current collector is: A current collector for a sliding contact line includes a current collector body for sliding conductive contact with the sliding contact line and a connecting assembly for connecting a mobile device. The connecting assembly has a fixed end for fixing to the mobile device and a floating end for floatingly connecting to a portion of the current collector body located outside the sliding contact line. The floating end has a limiting structure surrounding the current collector body. The current collector body has a limiting cavity with upper and lower limiting walls. The limiting structure has a limiting mating part located within the limiting cavity. The distance between the upper and lower limiting walls of the limiting cavity is sufficient to allow the limiting mating part to have vertical movement so that the current collector body can float relative to the limiting structure when the mobile device moves the current collector body on the sliding contact line via the connecting assembly.

[0006] Furthermore, the limiting structure includes a main board and two connecting ears respectively provided at both ends of the main board along the moving direction of the current collector on the sliding contact line. The connecting ears are integrally bent based on the main board. The two connecting ears are located on opposite sides of the current collector body. The ends of the two connecting ears protrude from the side of the current collector body and are connected by a connecting rod. The connecting rod cooperates with the main board to limit the relative position of the current collector body and the floating end.

[0007] Furthermore, the current collector body has limiting cavities at both ends along the sliding contact line current collector movement direction, and two connecting ears are located in the two limiting cavities respectively, the connecting ears constituting the limiting mating part.

[0008] Furthermore, the connecting rod is mounted on the connecting ear, and the end of the connecting rod is provided with an anti-detachment structure to keep the connecting rod connected to the connecting ear.

[0009] Furthermore, the limiting cavity is a limiting groove with its opening facing the horizontal side.

[0010] Furthermore, the moving direction of the sliding contact line current collector is defined as the front-to-back direction, and the limiting groove is provided on the side of the current collector body in the front-to-back direction, and the limiting groove runs through the left-to-right direction.

[0011] Furthermore, the connecting component includes a main body connecting part and a device connecting part, with the floating end located in the main body connecting part and the fixed end located in the device connecting part. The main body connecting part and the device connecting part are hinged by a first hinge, and the hinge axis direction is consistent with the moving direction of the sliding contact line current collector.

[0012] Furthermore, the equipment connection part includes an adapter part and a fixed part. The adapter part is connected to the first hinge, the fixed end is located in the fixed part, and the fixed part and the adapter part are hinged by a second hinge with the hinge axis direction consistent with the moving direction of the sliding contact line current collector.

[0013] Furthermore, the main connecting part is a connecting plate, the transition part is a transition plate, and the fixing part is a fixing plate. The width direction of the connecting plate, transition plate, and fixing plate is consistent with the sliding direction of the current collector.

[0014] Furthermore, both the connecting plate and the fixing plate are set vertically, and the adapter plate is set at an angle to both the connecting plate and the fixing plate.

[0015] Beneficial effects: This utility model improves upon existing sliding contact line current collectors by forming a floating connection between the current collector body and the connecting component. The limiting structure at the floating end of the connecting component surrounds the current collector body, limiting its position and maintaining the relative position between the floating end and the current collector body. The connecting component can drag the current collector body to move by the limiting structure surrounding it. Simultaneously, a limiting cavity is provided on the current collector body, with the limiting mating part of the corresponding limiting structure located within the cavity. The upper and lower limiting walls of the cavity allow the limiting mating part a certain amount of vertical movement within the cavity, enabling the current collector body to float vertically relative to the connecting component. Thus, when the mobile device moves, the connecting component drives the current collector body to move along the sliding contact line. During the movement of the current collector body, it can adaptively adjust its position according to the undulations of the sliding contact line and the changes in the distance between the mobile device and the sliding contact line, reducing the likelihood of poor contact or sliding jamming.

[0016] Furthermore, the hinged structure allows the current collector to be adjusted in both vertical and horizontal directions as it moves along the conductor rail, with ample vertical adjustment capability, ensuring smooth sliding of the current collector. Using sheet metal for force transmission, with the width of the plate as the direction of force application, helps ensure load-bearing capacity in the direction of movement, resulting in reliable operation.

[0019] The basic concept of this utility model's sliding contact line current collector is to form a vertically floating connection structure between the current collector's main body and the connecting components. This vertical floating allows the current collector to adaptively adjust its position relative to the sliding contact line, adapting to changes in the height of the sliding contact line and the relative height of the mobile device. This reduces the likelihood of poor contact or mechanical jamming between the current collector and the sliding contact line. Furthermore, the hinged structure enables adjustment in both vertical and horizontal directions, further ensuring smooth sliding and reliable contact.

[0020] The following detailed description is provided in conjunction with specific embodiments. Embodiments of the sliding contact line current collector of this utility model: like Figure 1 , Figure 2 , Figure 3 As shown, the sliding contact line current collector includes a current collector body 2 and a connecting component 3. The current collector body 2 is connected to the sliding contact line 1, and the connecting component 3 is connected to the mobile device 4. When the mobile device 4 moves, it drives the current collector body 2 to move on the sliding contact line 1 through the connecting component 3.

[0021] This current collector is used in electric hoist equipment, and the corresponding mobile device 4 is the electric hoist equipment. The electric hoist equipment is suspended on a rail, which can be made of I-beams or H-beams. The electric hoist equipment includes a traveling trolley, on which traveling wheels 41 are mounted. There are traveling wheels 41 on both sides of the rail, and the traveling wheels 41 are supported on the rail. There are two traveling wheels 41 on the same side of the rail. The traveling wheels 41 are rolled and supported on the upper side of the lower flange of the rail, and can move horizontally through the traveling wheels 41. The traveling motor and the lifting motor are mounted on the frame of the traveling trolley, and the traveling motor and the lifting motor need to be powered when they are working. The sliding contact line 1 is fixedly installed on the track parallel to the track. The sliding contact line 1 is fixed on the lower side of the upper flange of the track. The extension direction of the sliding contact line 1 is the same as the extension direction of the track. The current collector is connected to the frame of the trolley through the connecting component 3. The current collector is slidably connected to the sliding contact line 1. During the movement of the trolley, the sliding contact line 1 supplies power to the current collector. The current collector is electrically connected to the travel motor and the lifting motor through cables to realize the power supply of the travel motor and the lifting motor.

[0022] The sliding contact line 1 has a downward-facing groove with a conductor inside. The current collector body 2 has a contact portion extending into the groove, which includes a carbon brush to form conductive contact with the conductor of the sliding contact line 1. A portion of the current collector body 2 extends downward and protrudes from the outside of the sliding contact line 1. The lower end of this portion has a cable connection structure for connecting a corresponding motor via a cable. The portion of the current collector body 2 located below the sliding contact line 1 is connected to the frame of the mobile device 4, where the wheels 41 are located, via a connecting assembly 3.

[0023] The connecting assembly 3 mainly consists of a connecting plate 30, a first hinge 31, an adapter plate 32, a second hinge 33, and a fixing plate 34. The connecting assembly 3 has a fixed end for fixing to the mobile device 4 and a floating end for floating connection with the portion of the current collector body 2 located outside the sliding contact line 1. The fixed end is located on the fixing plate 34, and the floating end is located on the connecting plate 30. The floating end of the connecting assembly 3 has a limiting structure surrounding the current collector body 2. The current collector body 2 has a limiting cavity with upper and lower limiting walls. The limiting structure has a limiting mating part located within the limiting cavity. The distance between the upper and lower limiting walls of the limiting cavity allows the limiting mating part to have vertical movement so that when the mobile device 4 moves the current collector body 2 on the sliding contact line 1 via the connecting assembly 3, the current collector body 2 can float vertically relative to the limiting structure of the floating end of the connecting assembly 3.

[0024] The current collector body 2 and the connecting component 3 are connected in a floating manner. The limiting structure of the floating end of the connecting component 3 surrounds the current collector body 2, limiting its position around the current collector body 2 and maintaining the relative position between the floating end and the current collector body 2. The connecting component 3 can drag the current collector body 2 to move by the limiting structure surrounding the current collector body 2. At the same time, a limiting cavity is provided on the current collector body 2, and the limiting mating part of the corresponding limiting structure is located in the limiting cavity. The upper and lower limiting walls of the limiting cavity allow the limiting mating part to have a certain amount of vertical movement within the limiting cavity, thereby allowing the current collector body 2 to float up and down relative to the connecting component 3. In this way, when the mobile device 4 moves, the current collector body 2 is driven to move on the sliding contact line 1 by the connecting component 3. During the movement of the current collector body 2, it can adaptively adjust its position according to the undulation of the sliding contact line 1 and the change in the distance between the mobile device 4 and the sliding contact line 1, making it less likely to have poor contact or sliding jamming.

[0025] The current collector's movement direction is defined as the front-to-back direction, which is also the extension direction of the sliding contact line 1. The sliding contact line 1 is located above the mobile device 4 and on the left-to-right side of the connection between the connecting component 3 and the mobile device 4. The current collector body 2 is generally square, with front and back sides and left and right sides, and the right side is defined as the side facing the walking wheel 41.

[0026] The limiting structure includes a main body portion of the connecting plate 30 and two connecting ears 35 respectively provided at the front and rear ends of the main body portion. The connecting ears 35 are integrally bent based on the main body portion. The two connecting ears 35 are located on opposite sides of the front and rear of the current collector body 2. The ends of the two connecting ears 35 face to the left and protrude from the left side of the current collector body 2. The ends of the two connecting ears 35 are connected by a connecting rod 36. The connecting rod 36 and the main body portion of the connecting plate 30 are respectively located on the left and right sides of the current collector body 2. The connecting rod 36, the main body portion of the connecting plate 30, and the connecting ears 35 surround the four sides of the current collector body 2, cooperating with each other to limit the relative position of the current collector body 2 and the floating end of the connecting component 3. The structure is simple, easy to form, and convenient to install and operate. In other embodiments, a clamp can also be used as the limiting structure. The clamp is a two-half structure that can be fastened to the current collector body to ensure that there is a vertical floating gap.

[0027] The current collector body 2 has limiting cavities at both its front and rear ends. These limiting cavities are limiting grooves 21 located on the corresponding sides. Two connecting ears 35 are located within the two limiting cavities, forming a limiting fit. The connecting ears 35 on both sides form a limiting fit with the current collector body 2, facilitating the formation of limiting cavities on the current collector body 2. Simultaneously, the connecting ears 35 on both sides ensure reliable connection between the current collector body 2 and the connecting assembly 3 during the forward and backward movement of the current collector body 2. In other embodiments, a limiting protrusion can be provided on the left side of the current collector body. This protrusion has a through hole for the connecting rod to pass through, allowing the connecting rod to move up and down within the hole. The through hole forms a limiting cavity, and the connecting rod forms a limiting fit.

[0028] The connecting lug 35 has a through hole, through which the connecting rod 36 is threaded. Both ends of the connecting lug 35 pass through the connecting lugs on both sides. Both ends of the connecting rod 36 have an anti-detachment structure to maintain the connection between the connecting rod 36 and the connecting lug 35. The anti-detachment structure can be achieved by bending a section of the connecting rod 36 that passes through the connecting lug 35 to one side of the connecting lug 35. The bending angle can be 90 degrees, and the bent sections at both ends of the connecting rod 36 form an anti-detachment structure on opposite sides of the connecting lug 35. Alternatively, a pin can be radially threaded through the end of the connecting rod 36 to achieve anti-detachment. In other embodiments, the connecting rod can also be welded to the connecting lug.

[0029] The connecting rod 36 located on the left side of the current collector body 2 and the main board part of the connecting plate 30 located on the right side of the current collector body 2 do not affect the vertical floating of the current collector body 2. They can be in contact, have a gap, or have a very small clamping force. The connecting ears 35 on the front and rear sides do not clamp the current collector body 2 in the front-back direction. In the vertical direction, the width of the connecting ears 35 is smaller than the width of the limiting groove 21 to ensure the vertical floating ability of the current collector body 2. The floating amount is small, and correspondingly, the fit gap between the connecting ears 35 and the inner wall of the limiting groove 21 is also small.

[0030] In this embodiment, the limiting cavity is a limiting groove 21 with its opening facing the horizontal side. In other embodiments, limiting holes that penetrate the opposite sides of the current collector body can also be used as limiting cavities. In this embodiment, the limiting groove 21 is provided on the side of the current collector body 2 in the front-rear direction. The limiting groove 21 penetrates in the left-right direction, and the openings of the front and rear limiting grooves 21 are opposite to each other. The upper and lower groove walls of the limiting groove 21 form upper and lower limiting walls, which can prevent the current collector body 2 from separating from the connecting component 3, while allowing it to have a certain amount of vertical relative movement.

[0031] The connecting plate 30 constitutes the main connecting part of the connecting assembly 3. The connecting plate 30 is connected to the adapter plate 32 via the first hinge 31. The adapter plate 32, the second hinge 33, and the fixing plate 34 constitute the equipment connecting part of the connecting assembly 3. The floating end is located in the main connecting part. The main connecting part and the equipment connecting part are hinged via the first hinge 31, and the hinge axis is aligned with the moving direction of the sliding contact line current collector. The adapter plate 32 constitutes the adapter part of the equipment connecting part, and the fixing plate 34 constitutes the fixing part of the equipment connecting part. The fixing end is located in the fixing part, and the fixing part and the adapter part are hinged via the second hinge 33, and the hinge axis is aligned with the moving direction of the sliding contact line current collector. The hinges allow the current collector body 2 to have a range of motion in the left and right directions, enabling adjustment of the left and right positions. The cooperation of two hinges increases the adjustment margin in the up and down directions of the current collector body 2, enhancing its self-adjusting capability. In other embodiments, only one hinge may be provided, or no hinge may be provided at all.

[0032] Both the first hinge 31 and the second hinge 33 are hinges, each with two leaf blades and a hinge axis. The two leaf blades connect to corresponding connecting plates and can be fixed together with bolts. The hinges are made of 304 stainless steel, with a thickness of at least 2mm and a size of at least 4 inches. Holes are drilled at the mating points between the hinges and the plates. Stainless steel hex bolts are used for bolt connection, and spring washers and flat washers are required for nut installation. The tensile strength of the bolts and nuts is at least 8.8 grade. The hinge connection position is determined based on the height difference between the electric hoist and the sliding contact line 1, ensuring flexible movement after the hinges are installed on the plates.

[0033] The connecting plate 30, the adapter plate 32, and the fixing plate 34 are made of 3mm thick stainless steel plates. The width direction of the connecting plate 30, the adapter plate 32, and the fixing plate 34 are all consistent with the sliding direction of the current collector. The thickness direction of the plate is on a vertical plane perpendicular to the front and back direction. The plate is used to transmit force, and the width direction of the plate is the direction of force. This helps to ensure the load-bearing capacity in the moving direction, making it reliable and rigid. It can avoid damage to the current collector due to insufficient strength during high-speed movement.

[0034] Both the connecting plate 30 and the fixing plate 34 are vertically arranged. The adapter plate 32 is set at an angle to both the connecting plate 30 and the fixing plate 34, and this angle is not constant. The connecting plate 30 is not fixedly connected to the current collector body 2, but can move up and down relative to it. It is used in conjunction with the first hinge 31 and the second hinge 33 to achieve a large range of vertical adjustment of the current collector in the sliding contact line 1.

[0035] The fixing plate 34 is fixed to the vertical side of the frame with bolts, and the hinge is fixed to the plate surface. The lower part of the connecting plate 30 is fixedly connected to the first hinge 31. The upper part of the connecting plate 30 forms the main plate part. Connecting ears 35 are integrally provided on the front and rear sides of the main plate part. The bending position of the connecting ears 35 relative to the main plate part can be referred to Figure 3 The bending line 37 in the middle. The connecting plate 30 holds the current collector body 2 through the connecting ears 35 on both sides and maintains the connection with the connecting rod 36, so that the current collector can move with the mobile device.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features.
