Description

Technical Field

[0001] The utility model relates to the technical field of cable laying and protection, in particular to a mobile power supply cable protection device for electrical equipment. 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 line of the operation site to provide power supply to the equipment through the contact shoe method. This method occupies more on-site operation space, and the sliding wire is exposed in the operation 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 safety of the gantry crane power supply. However, when using cable power supply in actual operation, there are unsafe situations such as the cable easily breaking during the switching process, the cables along the line easily being crushed when placed on the ground, and the cable outer insulation easily being worn on the cable reel, 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, to prevent the laid cables from being damaged by rolling or trampling, or causing the cables to break during the switching process, or causing wear during the winding process of the reel, so as to improve 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 a mobile power supply cable protection device for protecting the cables laid on the ground to prevent them from being crushed, broken or worn, thereby making the cables safer and more reliable during the power supply process.

[0005] In order to achieve the above purpose, the protective device disclosed in the utility model can adopt the following technical solutions:

[0006] A mobile power supply cable protection device, comprising:

[0007] A plurality of anti-crush cable seats are continuously spliced ​​and laid on the foundation surface along the direction of the cable to form two groups of anti-crush cable seat groups, the two groups of anti-crush cable seat groups are aligned with each other and respectively form cable channels for accommodating the cables, and at the same time form a crushing surface for supporting vehicles to pass through to protect the cables;

[0008] The cable reversing assembly is arranged between two sets of anti-crush cable seat assemblies and is used to reverse the cable between two cable channels;

[0010] The cable protection device disclosed above accommodates and protects the cable through an anti-crushing cable seat to prevent the cable from being crushed and damaged by passing vehicles; at the same time, the cable is wound and unwound in coordination with the movement of the electrical equipment, and the cable winding assembly is used to guide the cable during the winding and unwinding process, so that the winding and unwinding of the cable are smooth and safe, avoiding the wear of the cable; when the electrical equipment moves and crosses from one cable channel to another, the direction of the cable is adjusted by the cable reversing assembly to flip it, thereby avoiding the breakage of the cable. The cable protection device provided in the utility model can provide multi-faceted protection for the cable in combination with the working movement process of the electrical equipment.

[0011] Furthermore, the cable reversing assembly can be constructed into a variety of structures to achieve a 180° flip of the cable in a flat state. Its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the cable reversing assembly includes a base plate, a reversing seat and a pressure plate seat are arranged on the base plate, and a fixed clamping channel for clamping the cable is formed between the reversing seat and the pressure plate seat; the pressure plate seat is also connected to a steering member, and a movable clamping channel for clamping the cable is formed on the steering member. When such a scheme is adopted, the base plate is arranged on the base surface and fixed by a connecting member; a cable cover for protecting the cable can be arranged between the reversing seat and the pressure plate seat, and the cable cover is wrapped around the surface of the cable, close to the inner wall surface of the fixed clamping channel and clamped by the reversing seat and the pressure plate seat.

[0012] Furthermore, in the present invention, the structure of the steering member can be constructed in a variety of forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the steering member includes a flip plate, the lower end of which is connected to the pressure plate seat through a flip shaft and flipped within a range of 180 degrees. When such a solution is adopted, the steering member can also be constructed as an L-shaped flip rod, the lower part of which is directly connected to the pressure plate seat, and the side part is used to cooperate to form a movable clamping channel.

[0013] Furthermore, in the present invention, the movable clamping channel can be constructed in a variety of forms, which are not limited to the only one. Here, an optimization is made and one of the feasible options is proposed: the flip plate is provided with a flip seat, the flip seat is connected to the flip pressure seat to form a movable clamping channel, and the movable clamping channel flips synchronously with the flip plate and is perpendicular to the fixed clamping channel. When such a solution is adopted, the fixed clamping channel fixes and clamps the first section of the cable and keeps the cable stable, the movable clamping channel fixes and clamps the second section of the cable and drives the second section to deflect, and maintains the vertical relationship between the first section and the second section, thereby avoiding repeated bending and damage of the cable during the process of realizing the cable deflection.

[0014] Furthermore, in the present invention, the cable is guided to the winding drum by a guide to reduce friction damage between the cable and the side structure. The guide can be constructed in a variety of forms, which are not limited to a single form. Here, an optimization is made and one of the feasible options is proposed: the guide includes a guide frame, the guide frame forms a first guide part and a second guide part and is respectively arranged in the direction of forward and backward movement of the electrical equipment, a swing guard is arranged between the first guide part and the second guide part, and the swing guard includes a swing frame arranged on the guide frame, and two protective wheels are arranged on the swing frame in opposite places to form a guide hole for the cable to pass through. When such a solution is adopted, the cable extends from the cable channel through the first guide part or the second guide part, and can be better aligned with the winding wheel after passing through the guide hole. The first guide part and the second guide part include two guide arms respectively formed from the guide frame, and the guide arms are provided with guide wheels. The cable passes over the guide wheels and rolls with the guide wheels to avoid wear of the cable; when the cable enters the guide hole, it also rolls with the protective wheel to also avoid wear of the cable; grooves are provided on the guide wheel and the protective wheel to cooperate with the cable, ensuring that the cable maintains a gap with the guide frame or swing frame on the side to avoid friction.

[0015] Furthermore, in order to better guide the cable to the winding wheel, the structure of the guide frame is adjusted and optimized. Here, an optimization is performed and one of the feasible options is proposed: two alignment rollers are arranged in parallel on the guide frame, and an alignment channel is formed between the alignment rollers and used to align the cable with the winding reel. When such a solution is adopted, the gap width between the alignment rollers is the width of the alignment channel, which is the same as the diameter of the cable, thereby improving the restriction on the cable and making the alignment direction of the cable better.

[0016] Furthermore, the structure of the anti-crush cable seat is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the anti-crush cable seat includes a base, a cable storage groove for placing cables is formed on the base, and a cover assembly and a linkage mechanism are also provided; wherein the cover assembly includes cover plates that are relatively arranged and used to close or open the cable storage groove, and the relatively arranged cover plates are matched through the linkage mechanism to synchronously flip and open. When such a scheme is adopted, the width of the cable storage groove is greater than or equal to the diameter of the cable. When a vehicle needs to pass the cable, the vehicle rolls over and contacts the cover assembly and applies force to the cover assembly, and the linkage mechanism causes the relative cover plates to close synchronously to close the cable storage groove, thereby forming a support surface and supporting the cable, thereby preventing the cable from being crushed and damaged.

[0017] Furthermore, the structure of the cover plate can be constructed in a variety of forms to provide a support force of sufficient strength. Here, an optimization is made and one of the feasible options is proposed: the cover plate includes a plurality of connecting rods and a support plate, 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 can strengthen the strength of the support plate and improve the overall support performance of the cover plate, thereby ensuring the anti-crushing effect when facing the situation of crushing caused by passing vehicles.

[0018] Furthermore, in the present invention, covers are provided on both sides of the cable storage slot. No matter which side the vehicle starts rolling from, the covers on both sides can be automatically closed to form a support surface. This process is realized by a linkage mechanism. The linkage mechanism can be constructed in a variety of forms, which are not limited to a single form. 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 position slide groove is provided on the base, and the synchronization pin is located in the limited position slide groove and limits the synchronous movement of the linkage rod in the longitudinal direction.

[0048] The present embodiment provides a mobile power supply cable protection device for electrical equipment, which aims to provide multiple protections for the cable 0, prevent it from being crushed after being laid, and avoid bending, abrasion, etc. during the movement of the electrical equipment 6, thereby effectively ensuring the safe and reliable use of the cable 0.

[0049] Specifically, Figures 11 to 16 As shown, as a power supply cable protection device disclosed in this embodiment, one of its structures includes:

[0050] Several anti-crushing cable seats are continuously spliced ​​and laid on the foundation surface along the direction of cable 0 to form two groups of anti-crushing cable seat groups. The two groups of anti-crushing cable seat groups are aligned with each other and respectively form cable channels for accommodating cable 0, while forming a crushing surface to support the passage of vehicles to protect cable 0.

When such a scheme is adopted, the width of the cable storage groove 103 is greater than or equal to the diameter of the cable 0. When a vehicle needs to pass through the cable 0, the vehicle rolls over and contacts the cover assembly 2 and applies force to the cover assembly 2, and the linkage mechanism 3 causes the relative covers to close synchronously to close the cable storage groove 103, thereby forming a support surface and supporting the cable 0, thereby preventing the cable 0 from being damaged by crushing.

This embodiment is optimized and adopts one of the feasible options: the linkage mechanism 3 includes a linkage rod 32 that cooperates with the cover plate. The front end of the linkage rod 32 contacts and cooperates with the cover plate and transmits.

[0058] In this embodiment, the structure of the steering member 405 can be constructed in various forms, which are not limited to the only one. This embodiment is optimized and adopts one of the feasible options: the steering member 405 includes a flip plate, the lower end of which is connected to the pressure plate seat 403 through a flip shaft 4051 and flipped within a range of 180 degrees. When such a solution is adopted, the steering member 405 can also be constructed as an L-shaped flip rod, the lower part of which is directly connected to the pressure plate seat 403, and the side part is used to cooperate to form a movable clamping channel.

The guide member 5 includes at least two guide parts 503 and is used to cooperate with the reversal and flipping of the cable 0.

[0063] In this embodiment, the cable 0 is guided to the winding drum 8 by the guide 5 to reduce the friction damage between the cable 0 and the side structure. The guide 5 can be constructed in various forms, which are not limited to the only one. This embodiment is optimized and adopts one of the feasible options: the guide 5 includes a guide frame 501, the guide frame 501 forms a first guide part 503 and a second guide part 503 and is respectively arranged in the direction of the forward and backward movement of the electrical equipment 6, and a swing guard 505 is arranged between the first guide part 503 and the second guide part 503. The swing guard 505 includes a swing frame 5051 arranged on the guide frame 501, and two protection wheels 5053 are arranged on the swing frame 5051 to form a guide hole for the cable 0 to pass through. When such a solution is adopted, the cable 0 extends from the cable channel through the first guide part 503 or the second guide part 503, and can be better aligned with the winding drum 8 after passing through the guide hole. The first guide part 503 and the second guide part 503 include two guide arms respectively formed from the guide frame 501, and the guide arms are provided with guide wheels 504. The cable 0 passes around the guide wheels 504 and rolls with the guide wheels 504 to avoid wear of the cable 0; when the cable 0 enters the guide hole, it also rolls with the protective wheel 5053 to also avoid wear of the cable 0; grooves are provided on the guide wheel 504 and the protective wheel 5053 to cooperate with the cable 0, ensuring that the cable 0 maintains a gap with the guide frame 501 or the swing frame 5051 next to it to avoid friction.

[0066] In order to better guide the cable 0 onto the winding wheel, the structure of the guide frame 501 is adjusted and optimized. This embodiment optimizes and adopts one of the feasible options: two alignment rollers 506 are arranged in parallel on the guide frame 501, and an alignment channel is formed between the alignment rollers 506 and used to align the cable 0 with the winding drum 8. When such a solution is adopted, the gap width between the alignment rollers 506 is the width of the alignment channel, which is the same as the diameter of the cable 0, thereby improving the restriction on the cable 0 and making the alignment direction of the cable 0 better.

[0084] Preferably, a gear structure 3201 is formed at the front end of the linkage rod 32 to cooperate with the cover plate assembly 2 .

[0085] In this embodiment, the structure of the linkage rod 32 can be set in various forms to achieve synchronous action, and its structure is not limited to a single one.

When such a solution is adopted, the linkage mechanism 3 is located inside the settlement area 104, so that the overall structural integrity of the anti-crushing device is higher, and the linkage mechanism 3 is embedded in the settlement area 104 as a whole.
