Description
Technical Field
[0001] The utility model relates to the technical field of cable laying and protection, in particular to an automatic anti-crushing device for cables. Background Art
[0002] For outdoor equipment operating in complex working environments such as construction sites, vehicle access roads, and personnel walking passages, reliable power supply is the primary technical condition to ensure the safe operation of the equipment. For example, the movable gantry cranes at hydropower stations and docks can continuously move back and forth to adjust the working position according to the actual work needs on site. They are used for lifting equipment, material transfer, maintenance and auxiliary cooperation and other production work. They are commonly used equipment for outdoor lifting operations. Therefore, the safe operation of gantry cranes is directly related to the safe production of hydropower stations and docks. Therefore, the safe operation of gantry cranes themselves is particularly important. At present, there are two common power supply methods for gantry cranes: sliding wire and cable power supply. When using sliding wire power supply, it is necessary to set up a power supply sliding wire along the working site to provide power supply to the equipment through the contact shoe method. This method occupies more on-site working space, and the sliding wire is exposed in the working area, which poses certain safety risks. Therefore, outdoor gantry cranes mostly use cables to provide power supply for the equipment. When using cable power supply, during the reciprocating movement of the gantry crane, the reel is driven by the motor to retract and release the cable according to the walking direction to ensure the power supply safety of the gantry crane. However, in actual operation of the cable power supply method, the cables are placed on the ground and are subject to being crushed or stepped on, which poses a safety hazard.
[0003] It can be seen that there is still room for improvement in the cable power supply solution, and optimization should be carried out to improve the protection of the cables, prevent the laid cables from being crushed or trampled and damaged, thereby improving the safety and reliability of power supply. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Utility Model Content
[0004] In order to overcome at least one of the defects mentioned above, the utility model proposes an automatic anti-crushing device for cables, which implements anti-crushing protection for cables that need to be frequently retracted and released, and provides safety protection for the power supply cables placed on the ground of gantry cranes during the frequent retraction and release process, thereby ensuring safe and reliable operation of the crane equipment.
[0005] In order to achieve the above-mentioned purpose, the automatic anti-crushing device for cables disclosed in the utility model can adopt the following technical solutions:
[0006] An automatic anti-crushing device for a cable, comprising:
[0007] The base is fixed and used to set cables. A cable storage groove is provided on the base. The front and rear sides of the base form rolling slopes for vehicles to pass through.
[0008] The cover plate assembly includes cover plates arranged on both sides of the cable storage slot and used to cover, close or open the cable storage slot; the cover plate is rotatably connected to the base and an elastic reset member is arranged at the connection, the elastic reset member is used to apply a restoring force to the cover plate to return the cover plate to an initial position, when a vehicle crosses the base, it acts on one side of the cover plate and closes the other side of the cover plate in linkage, the rolling slope and the cover plate form a smooth passing surface for rolling passage;
[0009] The linkage mechanism is used to flexibly connect two opposite cover plates and enable the two cover plates to be opened or closed synchronously.
[0010] The automatic anti-crushing device disclosed above uses a base as a load-bearing part for fixing on the ground or a basic component. The cable is located in a cable storage groove inside the base, and the cover plate assembly can cover the cable storage groove to protect the cables therein. Since the cover plate assemblies are arranged on both sides of the cable storage groove, a linkage mechanism is provided to realize synchronous opening or synchronous closing of the cover plates. When the cover plates are opened, they are in an upright state, which can remind the staff to pay attention to the cables. When the cover plates are closed, a support surface is formed, which can withstand vehicle crushing and protect the cables below. Also because of the provision of a linkage mechanism, when the cover plate on one side is deflected by force, the cover plate on the other side also deflects synchronously.
[0011] Furthermore, the linkage mechanism in the utility model can be constructed in a variety of forms to achieve the synchronous action of the cover plate, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the linkage mechanism includes a linkage rod that cooperates with the cover plate, the front end of the linkage rod contacts and cooperates with the cover plate and transmits, and the rear end of the linkage rod cooperates with the relative linkage rod through a synchronization pin to form a synchronous linkage structure; a limited sliding groove is provided on the base, and the synchronization pin is located in the limited sliding groove and limits the synchronous action of the linkage rod in the longitudinal direction. When such a scheme is adopted, the limited sliding groove can be set as a strip groove extending in the height direction and horizontally passing through the base, and a synchronization pin is set and its two ends extend to the outside of the limited sliding groove to cooperate with the linkage rod; when the cover plate on one side is deflected by force, the linkage rod is driven to move and the synchronization pin is driven to move in the longitudinal direction, and the synchronization pin drives the linkage rod and the cover plate on the other side to synchronize, thereby realizing the synchronous opening or closing of the cover plates on both sides.
[0012] Furthermore, in the present invention, the structure of the linkage rod can be set in a variety of forms to achieve synchronous action, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the front end of the linkage rod is connected to the base through the second rotating shaft, and the front end of the linkage rod is meshed with the cover plate, and when the cover plate deflects, the linkage rod is driven to deflect synchronously; the rear end of the linkage rod forms a strip-shaped synchronization hole and cooperates with the synchronization pin, and when the linkage rod deflects, the synchronization hole limits the deflection angle range of the linkage rod. When such a scheme is adopted, the synchronization hole extends along the length direction of the linkage rod, and the front end of the linkage rod forms a cylindrical meshing portion, and meshing teeth are formed on the cylindrical side surface of the meshing portion; correspondingly, a corresponding meshing portion and meshing teeth are also formed on the cover plate.
[0013] Furthermore, in order to make the structure of the anti-crushing device more integrated and reduce the exposure of structural components, an optimization is made here and one of the feasible options is proposed: the left and right sides of the base form a settlement area, and the linkage mechanism is arranged in the settlement area. When such a solution is adopted, the linkage mechanism is located inside the settlement area, so that the overall structural integrity of the anti-crushing device is higher, and the linkage mechanism is embedded in the settlement area as a whole.
[0014] Furthermore, the cover assembly arranged on the base is used to open or close the cable storage slot to protect the cables. The specific setting method is based on the realization of automatic opening and closing of the cover assembly. The diverse structures are not limited to the only one. Here, optimization is carried out and one of the feasible options is proposed: a plurality of cover connecting seats are formed on the base, and avoidance grooves are formed between adjacent cover connecting seats. The cover is connected to the cover connecting seat through a first rotating shaft, and the elastic reset member is located in the avoidance groove. When such a scheme is adopted, the rotating shaft passes through multiple cover plate connecting seats in sequence, and corresponding rotating shaft holes are provided on the cover plate to realize the deflection of the cover plate; when the reset force is applied by the elastic reset member, a torsion spring member can be sleeved on the rotating shaft, and the initial position of the cover plate can be set to a state of vertically opening the cable storage slot. When a vehicle goes up to the base, pressure is applied to the cover plate to cause the torsion spring to elastically deform, and the cover plates on both sides of the cable storage slot are synchronously flipped to form a supporting surface for the vehicle to pass. When the vehicle passes, the cover plate is no longer subjected to pressure, and the cover plate is reversely deflected and returned to the initial position under the elastic reset force of the torsion spring.
[0015] Furthermore, when the cover plate deflects, a deflection limiting structure should be provided to stop the cover plate at a predetermined position, thereby forming a stable support surface. The limiting structure can be in various forms and is not limited to a single one. Here, an optimization is made and one feasible option is proposed: a support portion for limiting the deflection angle of the cover plate is formed on the base, and the top surface of the support portion is an inclined surface and is used to fit the cover plate. When the cover plate deflects to fit the inclined surface, the cable storage slot is closed. When such a solution is adopted, the support portion can be constructed as a long strip-shaped support protrusion, the overall length of which is equal to the length of the base, or a plurality of support protrusions can be arranged at intervals.
[0016] Furthermore, in order to maintain the strength of the cover plate and ensure that the cover plate can withstand sufficient pressure, the structure of the cover plate can be set to a variety of forms, which are not limited to the only one. Here, optimization is made and one feasible option is proposed: the cover plate includes a plurality of connecting rods and support plates, the connecting rods are arranged in parallel and rotated with the base, and the connecting rods are connected to the bottom surface or side of the support plate and used to drive the support plate to deflect synchronously. When such a solution is adopted, the connecting rods and the support plate can be integrally formed, and multiple connecting rods can be set to enhance the overall strength of the cover plate.
[0017] Furthermore, the structure of the cover plate can be optimized to improve the ability of the support surface to withstand pressure. Here, optimization is performed and feasible options are proposed: the front end of the connecting rod forms a bending structure. When the connecting rod is deflected and the support plate covers the cable storage slot, the front ends of the opposite connecting rods contact and press together to form a horizontal support portion through the bending structure; the support plate forms a bending surface with the connecting rod. When the connecting rod is deflected and the support plate covers the cable storage slot, the bending surface of the opposite support plate forms a horizontal support surface. When such a solution is adopted, the angle at the bending structure is an obtuse angle. When the opposite cover plates are deflected and pressed together, the two cover plates form an arched support surface, and the middle part of the support surface is a plane. In this way, the vertical pressure can be partially decomposed into the horizontal direction, thereby improving the pressure resistance performance.
[0018] Furthermore, in order to maintain the installation stability of the automatic anti-rollover device, the utility model adjusts and optimizes the structure of the base and proposes the following feasible option: the base is provided with a plurality of connection holes, and connecting pieces are provided at the connection holes to fix the base to the installation surface. When such a solution is adopted, the connection holes can be provided on the rolling slope surface of the base and connected to the ground or the installation foundation by connecting screws or the like.
[0019] The above content discloses the structure of the anti-crushing device, and the utility model also provides an anti-crushing method.
[0020] An automatic anti-crushing method for cables uses the automatic anti-crushing device described above. After the automatic anti-crushing device is set, when a vehicle moves and applies pressure to the cover plate, the cover plates on both sides of the cable storage groove are driven by a linkage mechanism to achieve synchronous deflection and close the cable storage groove, forming a supporting surface for vehicles to crush and pass through to protect the cable; when the vehicle passes, the cover plate is reset under the action of the elastic reset force applied by the elastic reset member.
