Abstract

This invention discloses a cable tray box and a handcart-type switch cabinet having the same, comprising a box body, a stripping component, an anti-pull component, and a straightening component. The stripping component, installed inside the box body, can strip the cable sheath. The anti-pull component, installed inside the box body, limits the cable winding and prevents the other end of the cable from being pulled or causing the cable end with the terminal to fall off during the stripping process. The straightening component, installed inside the box body, straightens the bent cable, restoring it to a straight state. By integrating the stripping component, the anti-pull component, and the straightening component, this invention achieves precise stripping, effective anti-pull, and automatic straightening, thereby improving cable routing efficiency, safety, and reliability. It solves the problems of inaccurate stripping, easy pulling of cables leading to loosening, and bending caused by clamping that exist in traditional handcart-type switch cabinets during the cable routing process.

Description

Technical Field

[0001] This invention relates to the field of power switchgear technology, and more specifically to a cable box and a handcart-type switchgear having the same. Background Technology

[0002] With the rapid development of smart grids, higher requirements are being placed on the intelligence, automation, and safety of power equipment. Handcart-type switchgear, as one of the important electrical devices in the power system, is widely used in critical scenarios such as power plants, substations, data centers, rail transit, and chemical enterprises. However, existing handcart-type switchgear has many problems in the wiring process, making it difficult to meet the high standards required by smart grids.

[0003] In existing handcart-type switchgear, the removal of cable sheaths during cable routing typically relies on manual operation or simple mechanical tools, making it difficult to achieve high-precision stripping. This results in inconsistent internal conductor lengths after stripping, affecting reliable connections to subsequent electrical components, increasing contact resistance, and reducing electrical performance. During the stripping process, one end of the cable is easily subjected to tensile force, causing loosening or even detachment of connected parts. This not only affects the normal operation of the equipment but may also cause safety hazards such as short circuits and electric shocks. To prevent the cable from being pulled during stripping, it is usually secured, but this method can easily lead to localized bending of the cable. If not corrected in time, the bent parts will affect the electrical performance and lifespan of the cable, increasing the risk of equipment failure. The existing handcart-type switchgear cable routing operation is complex, requiring manual stripping, securing, and straightening of each step, which is time-consuming and inefficient. Furthermore, it requires a high level of operator experience, making it susceptible to malfunctions due to human error.

[0004] Therefore, how to provide an intelligent, automated, and highly secure cable box is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a cable box and a handcart-type switch cabinet having the same, which integrates stripping components, anti-pull components and straightening components to achieve automatic, accurate and safe cable handling, improve cable routing efficiency and electrical connection reliability, meet the requirements of smart grid for intelligent, standardized and high-safety switching equipment, and solve the problems of inaccurate stripping, easy pulling of cables leading to loosening, and bending caused by clamping in traditional handcart-type switch cabinets during the cable routing process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ribbon cable box, comprising: The box body has through holes on its top and bottom walls for passing cables through; multiple support members are fixed to the inner wall of the box body; and an operating box communicating with its inner cavity is fixed to one outer wall of the box body. A stripping assembly includes a drive component, a support cylinder, a support rod, a cutting toothed ring, and a cutting tube. The drive component is rotatably connected within the operating box. Multiple support cylinders are fixed within the box via the support component. The outer wall of the support rod slides against the inner wall of the support cylinder, and its axis corresponds to the height direction of the box. The cutting toothed ring is driven by the drive component, and its lower end face rotatably abuts against the upper end faces of the multiple support rods. The sliding of the support rods drives the cutting toothed ring to move up and down. The annular cavity of the cutting toothed ring corresponds to the through hole. An installation cavity is provided between the annular inner wall and the annular outer wall of the cutting toothed ring. Multiple cutting tubes are located within the installation cavity. One end of each cutting tube is fixed to the annular outer wall, and the other end is slidably connected to a cutting blade. The drive component communicates with the inner cavity of the cutting tube via an air passage to drive the cutting blade to slide through the annular inner wall and contact the cable sheath. The rotation and up-and-down movement of the cutting toothed ring allow the cutting blade to strip the cable sheath. An anti-pull assembly, which is installed inside the housing to limit cable entanglement; A straightening assembly, which is installed inside the housing to straighten bent cables.

[0008] The beneficial effects of the technical solution of this invention are as follows: the cutting toothed ring is driven to rotate by the driving component. During the rotation of the cutting toothed ring, the cutting blade slides out of the inner wall of the ring and contacts the outer sheath of the cable to perform the cutting operation; at the same time, the cutting toothed ring is driven to move up and down by the support rod. During the up and down sliding of the cutting toothed ring, since the cutting blade is performing the cutting operation, the cut cable outer sheath can be peeled off as it slides up and down; the anti-pull component makes the cable entangled to prevent the other end of the cable from being pulled when peeling off the cable outer sheath; the straightening component can straighten the bent parts of the cable and keep the cable in a straight state.

[0009] Preferably, the driving component includes a tangent rod, a first gear, and a knob; the tangent rod extends from top to bottom through the operating box and its upper end is rotatably connected to the top wall of the operating box; the first gear is fixed to the tangent rod and meshes with the cutting toothed ring; the knob is fixed to the upper end of the tangent rod and located outside the operating box. The rotation of the tangent rod drives the cutting toothed ring to rotate for the cutting operation.

[0010] Preferably, the thickness of the cutting toothed ring is greater than the thickness of the first gear. This ensures that during the peeling process, the up-and-down movement of the cutting toothed ring remains engaged with the first gear.

[0011] Preferably, the driving component further includes a second gear, a U-shaped toothed plate, and a pressing cylinder; the second gear is fixed to the lower end of the tangent rod; the cutting cylinder includes a cylinder body, a cutting rod, a cutting baffle, and a cutting spring; one end of the cylinder body is closed and fixed to the annular outer wall, and the other end is open; the cutting baffle is fixed to the first end of the cutting rod and its circumference slides against the inner wall of the cylinder body; the cutting knife is fixed to the second end of the cutting rod and corresponds to the open end; one end of the cutting spring is fixed to the cutting baffle, and the other end is fixed to the closed end of the cylinder body; The inner wall of the U-shaped toothed plate is fixed with teeth that can mesh with the second gear; an extrusion rod is fixed to the outer wall of the closed end, and an extrusion disc is fixed to the end of the extrusion rod; the circumferential surface of the extrusion disc slides against the inner wall of the extrusion cylinder; the inner cavity of the extrusion cylinder is connected to the cylinder body through a conveying pipe to drive the sliding of the peeling baffle by air pressure.

[0012] The beneficial effects of the above technical solution are that the rotation of the second gear can drive the U-shaped toothed plate to move linearly. During the linear movement of the U-shaped toothed plate, the extrusion plate continuously supplies air into the cutting cylinder. Utilizing the principle of an air pump, as the air pressure inside the cutting cylinder increases, the cutting rod can be driven to slide, thereby causing the slicing blade to slide out of the annular inner wall to cut the cable sheath. After the cutting cylinder is depressurized, the cutting spring can drive the cutting rod to return to its original position.

[0013] Preferably, the peeling assembly further includes a peeling rod and a conveying cylinder; the lower end of the support rod is fixed with a support plate and the circumferential surface of the support plate slides against the inner wall of the support cylinder; the two ends of the support spring are respectively fixed to the support plate and the bottom wall of the support cylinder; The peeling rod includes a rod body, a fixed plate, a transmission rod, a push plate, a push rod, and a push disk; the rod body is rotatably connected to the box body; the fixed plate is fixed to one end of the rod body; one end of the transmission rod is hinged to the fixed plate, and the other end is hinged to one side of the push plate; there are two push rods, one end of which is vertically fixed to both ends of the other side of the push plate; the push disk is fixed to the other end of the push rod; the outer wall of the conveying cylinder is fixed to the support member; the circumferential surface of one of the push disks slides against the inner wall of the conveying cylinder; the inner cavity of the conveying cylinder is connected to the inner cavity of the support cylinder through an air supply pipe to drive the support plate to slide using air pressure.

[0014] The beneficial effect of the above technical solution is that, using the same principle of an air pump, the transmission rod drives the push plate to slide in the conveying cylinder and deliver air into the support cylinder during the rotation of the rod. As the air pressure in the support cylinder increases, it can push the support rod to slide up and down. When the support cylinder is depressurized, the support spring drives the support rod to reset.

[0015] Preferably, the anti-pull assembly includes an anti-pull rod, a U-shaped plate, a transmission cylinder, a push-pull cylinder, a rack, and a reinforcing gear; one end of the anti-pull rod is vertically rotatably connected to the inner wall of the box; the closed end of the U-shaped plate is fixed to the other end of the anti-pull rod, and its U-shaped groove corresponds to the through hole; The outer walls of both the transmission cylinder and the push-pull cylinder are fixed to the support member, and the outer periphery of the other push disk slides against the inner wall of the transmission cylinder; one end of the rack is fixed with a sealing disk that slides against the inner wall of the push-pull cylinder, and the other end protrudes from the push-pull cylinder; the inner cavities of the transmission cylinder and the push-pull cylinder are connected by a transmission pipe to drive the sealing disk to slide using air pressure; the reinforcing gear is fixed to the anti-pull rod and meshes with the rack to drive the U-shaped plate to rotate and limit the cable winding.

[0016] The beneficial effect of the above technical solution is that, using the same principle of an air pump, the rotation of the rod will also drive the sliding of the push plate in the transmission cylinder and deliver air to the push-pull cylinder. As the air pressure in the push-pull cylinder increases, it can drive the rack to move linearly. During the linear movement of the rack, it will drive the reinforcing gear to rotate the anti-pull rod, thereby causing the U-shaped plate to rotate and limit the cable winding.

[0017] Preferably, the straightening assembly includes a straightening rod, a bidirectional gear, and straightening wheels; there are two straightening rods, the bidirectional gear is fixed to one end of the straightening rod, and the two bidirectional gears mesh with each other so that the two straightening wheels rotate in opposite directions; the outer diameter of the straightening wheel is smaller than the outer diameter of the bidirectional gear; the straightening wheel is fixed to the straightening rod and corresponds to the area above the U-shaped plate; the multiple straightening wheels can roll against the outer wall of the cable to straighten the bent cable. Due to the diameter difference between the straightening wheel and the bidirectional gear, a gap is formed between the two straightening wheels for the cable to pass through. The two straightening wheels rotate in opposite directions, and when they contact the cable, they can guide the cable so that the bent cable returns to a straight state.

[0018] Preferably, the straightening assembly further includes a rotating rod and a restoring rod; one end of the rotating rod is vertically rotatably connected to the side wall of the housing, and the other end is fixed to a restoring cylinder; a ratchet is fixed to one end of the straightening rod away from the bidirectional gear; the ratchet is located inside the restoring cylinder, and a pawl that engages with the ratchet is fixed to the inner wall of the restoring cylinder; one end of the restoring rod is vertically rotatably connected to the inner wall of the housing and corresponds to the lower part of the rotating rod; a restoring gear that meshes with the rack is fixed on the restoring rod; the rotating rod and the restoring rod are driven by a sprocket assembly. Due to the presence of the ratchet and pawl, the straightening rod can only be restricted to rotating in one direction; when the anti-pull rod rotates, the rack will not drive the straightening rod to rotate; when the cable needs to be straightened, the rotating rod is rotated in the opposite direction of the rack's movement, causing the rotating rod to drive the straightening rod to rotate, and at the same time, under the transmission action of the sprocket assembly, the restoring gear on the restoring rod drives the rack to move in the opposite direction, thereby causing the U-shaped plate to flip and forcing the tangled cable to untangle, and the cable is restored under the action of the straightening wheel.

[0019] Preferably, the sprocket assembly includes a driving sprocket, a driven sprocket, and a chain; the driving sprocket is fixed to the rotating rod; the driven sprocket is fixed to the restoring rod; and the chain connects the driving sprocket and the driven sprocket.

[0020] The present invention also provides a handcart-type switch cabinet, which adopts a wiring box from the above-mentioned technical solution and further includes a cabinet body; multiple opening and closing frames are slidably connected to the cabinet body, and the multiple opening and closing frames are arranged vertically along the cabinet body; a mounting plate is fixed to the top surface of the cabinet door end of the opening and closing frame away from the cabinet body; multiple electrical components are bolted to the plate surface of the mounting plate; the number of boxes is multiple, and the multiple boxes are magnetically attracted to the plate surface of the mounting plate and correspond one-to-one with the multiple electrical components.

[0021] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a cable box and a handcart-type switch cabinet having the same, which has the following beneficial effects: 1) Improve stripping accuracy: The adjustable-depth stripping blade and synchronously rotating stripping gear enable precise stripping of the cable sheath, avoiding damage to the internal wires, ensuring consistent wiring length, and improving connection reliability.

[0022] 2) Prevent loose connections: The anti-pull component flexibly fixes the cable end near the stripped wire during the stripping process, effectively preventing the joint from loosening or falling off due to pulling, thus enhancing operational safety.

[0023] 3) Automatic cable deformation correction: The correction component can promptly repair bends caused by clamping or wiring, keeping the cable straight and ensuring its electrical performance and mechanical life.

[0024] 4) Improve wiring efficiency and intelligence: The overall structure is highly integrated and easy to operate, making it suitable for smart grid environments. It significantly speeds up the on-site wiring of handcart-type switchgear, reducing reliance on manual labor and error rates.

[0025] 5) Through the coordinated use of stripping, anti-pull and straightening components, automation, precision and safety are achieved in the wiring process, which significantly improves the efficiency of on-site installation and maintenance. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention discloses a cable box and a handcart-type switch cabinet with the same, aiming to solve the problems of existing technologies that make it difficult to precisely strip the outer sheath of cables, resulting in inconsistent lengths of internal conductors after stripping, affecting the reliable connection with electrical components, the cable end being easily subjected to tension during the stripping process, causing the connected parts to loosen or even fall off, posing a safety hazard, and the cable often being bent locally when fixed to prevent pulling, which, if not corrected in time, will affect its electrical performance and service life. The cable box in this embodiment integrates a stripping component, an anti-pull component, and a correction component, achieving precise stripping, effective anti-pull, and automatic correction, thereby improving cable routing efficiency, safety, and reliability.

[0031] See appendix Figure 4 According to embodiment 17, a cable box includes a box body 2, a stripping component 3, an anti-pull component 4, and a straightening component 5. The top and bottom walls of the box body 2 are provided with through holes 22 for passing cables through. Multiple support members are fixed to the inner wall of the box body 2. The support members are in the form of rods or tubes and are used to support the internal structure. An operating box 21 communicating with the inner cavity is fixed to one side of the outer wall of the box body 2. The stripping component 3 is installed in the box body 2 and the operating box 21 to strip the cable sheath. The anti-pull component 4 is installed in the box body 2 to limit the cable winding and prevent the other end of the cable from being pulled or the cable end with the terminal already connected from falling off during the stripping process. The straightening component 5 is installed in the box body 2 to straighten the bent cable and restore the cable to a straight state.

[0032] In this embodiment, the peeling assembly 3 includes a drive component, a support cylinder 33, a support rod 39, a cutting toothed ring 34, and a cutting cylinder 32; the drive component is rotatably connected inside the operating box 21; there are multiple support cylinders 33, which are fixed inside the box 2 by support components; the outer wall of the support rod 39 slides against the inner wall of the support cylinder 33, and its axis corresponds to the height direction of the box 2; the drive component communicates with the inner cavity of the support cylinder 33 through an air passage to drive the support rod 39 to slide; the cutting toothed ring 34 is driven by the drive component, and its lower end face is connected to the multiple support rods 39. The upper end face rotates and abuts against the support rod 39, which can drive the cutting toothed ring 34 to move up and down by sliding. The annular cavity of the cutting toothed ring 34 corresponds to the through hole 22. An installation cavity is provided between the annular inner wall and the annular outer wall of the cutting toothed ring 34. There are multiple cutting tubes 32 located in the installation cavity. One end of the cutting tube 32 is fixed on the annular outer wall, and the other end is slidably connected to the cutting blade 322, which can penetrate the annular inner wall and contact the cable sheath. The rotation and up and down movement of the cutting toothed ring 34 can cause the cutting blade 322 to peel off the cable sheath.

[0033] like Figure 6 and 7As shown, the support cylinder is fixed inside the box by the support member, and the sheathing toothed ring is supported inside the box by the support cylinder. The use of multiple support cylinders can ensure the stability of the sheathing toothed ring. The rotation of the sheathing toothed ring and the up and down movement of the support rod are driven by the drive member, thereby ensuring the stripping operation of the cable sheath.

[0034] To further optimize the above technical solution, the driving component includes a tangent rod 31, a first gear 312, and a knob 311; the tangent rod 31 passes through the operation box 21 from top to bottom and its upper end is rotatably connected to the top wall of the operation box 21; the first gear 312 is fixed on the tangent rod 31 and meshes with the cutting tooth ring 34; the knob 311 is fixed at the upper end of the tangent rod 31 and located outside the operation box 21.

[0035] like Figure 5 As shown in Figure 7, this embodiment has two cutting tubes arranged symmetrically along the radial direction of the cutting toothed ring. The annular inner wall of the cutting toothed ring has slots for the cutting blades to enter and exit. One side wall of the housing has an opening, and the operating box is fixed to the periphery of the corresponding opening. The operating box is connected to the inner cavity of the housing. A bearing is embedded in the top wall of the operating box, and the upper end of the cutting rod is interference-fitted with the inner ring of the bearing. The cutting rod is rotated manually or by turning a knob with a wrench. During rotation, the cutting rod uses the first gear to drive the cutting toothed ring to rotate. In practical applications, a 180° rotation of the cutting toothed ring is sufficient for the cutting blades on both cutting tubes to cut the cable sheath.

[0036] In this embodiment, the driving component further includes a second gear 313, a U-shaped toothed plate 35, and a pressing cylinder 36; the second gear 313 is fixed to the lower end of the tangent rod 31; the peeling cylinder 32 includes a cylinder body, a peeling rod 321, a peeling baffle 324, and a peeling spring 323; one end of the cylinder body is closed and fixed to the annular outer wall, and the other end is open; the peeling baffle 324 is fixed to the first end of the peeling rod 321 and its circumferential surface slides against the inner wall of the cylinder body; the peeling knife 322 is fixed to the second end of the peeling rod 321. And corresponding to the open end; one end of the cutting spring 323 is fixed to the cutting baffle 324, and the other end is fixed to the closed end of the cylinder; the inner wall of the U-shaped toothed plate 35 is fixed with teeth that can mesh with the second gear 313; the outer wall of the closed end is fixed with a pressing rod 351, and the end of the pressing rod 351 is fixed with a pressing disc 352; the circumferential surface of the pressing disc 352 slides against the inner wall of the pressing cylinder 36; the inner cavity of the pressing cylinder 36 is connected to the cylinder through the conveying pipe 361 so as to drive the sliding of the cutting baffle 324 by air pressure.

[0037] like Figure 8As shown, the U-shaped toothed plate is located inside the operating box and consists of a plate body and two strips that are vertically fixed on one side of the plate body. Teeth are fixed on the two opposite surfaces of the two strips. The second gear is located between the two strips and meshes with them. The rotation of the second gear can drive the U-shaped toothed plate to move linearly. Two extrusion rods are vertically fixed on the other side of the plate. There are two extrusion cylinders. The extrusion discs on the two extrusion rods are slidably connected to the two extrusion cylinders respectively. The two extrusion cylinders are connected to the two cutting cylinders through corresponding conveying pipes. Utilizing the principle of an air pump, the cutting rod drives the U-shaped toothed plate to move linearly during rotation, thereby causing the extrusion rod to move the extrusion discs in the extrusion cylinders. The movement of the extrusion discs can deliver air from the extrusion cylinders to the cutting cylinders. As the air in the cutting cylinders increases, the cutting rod drives the cutting blade to slowly contact the outer wall of the cable. That is, while the cutting toothed ring rotates, the cutting blade will slowly extend out of the groove on the inner wall of the ring and contact the outer sheath of the cable. As the cutting rod rotates, the air pressure in the cutting cylinders increases, providing a stable thrust for the cutting blade to perform the cutting operation.

[0038] To further optimize the above technical solution, the conveying pipe can be stretched and retracted (e.g., the conveying pipe is a corrugated pipe) to prevent the connection between the conveying pipe and the cutting cylinder and extrusion cylinder from breaking during the rotation of the cutting toothed ring.

[0039] To further optimize the above technical solution, a first one-way valve is provided on the conveying pipe. The first one-way valve controls that the gas can only be conveyed from the extrusion cylinder to the cutting cylinder. A first solenoid valve is provided on the outer wall of the cutting cylinder. After the cable sheath is stripped, the pressure in the cutting cylinder is released by opening the first solenoid valve, and the elastic restoring force of the cutting spring is used to reset the cutting rod and the cutting blade.

[0040] In this embodiment, the peeling assembly 3 further includes a peeling rod 37 and a conveying cylinder 38; a support plate 391 is fixed to the lower end of the support rod 39, and the circumferential surface of the support plate 391 slides against the inner wall of the support cylinder 33; the two ends of the support spring 392 are respectively fixed to the support plate 391 and the bottom wall of the support cylinder 33; the peeling rod 37 includes a rod body, a fixed disk 371, a transmission rod 372, a push plate 373, a push rod 374, and a push disk 375; the rod body is rotatably connected inside the box 2; the fixed disk 371 is fixed to one end of the rod body; the transmission... One end of rod 372 is hinged to fixed plate 371, and the other end is hinged to one side of push plate 373; there are two push rods 374, one end of which is vertically fixed to both ends of the other side of push plate 373; push plate 375 is fixed to the other end of push rod 374; the outer wall of conveying cylinder 38 is fixed to support member; the circumferential surface of one of the push plates 375 slides against the inner wall of conveying cylinder 38; the inner cavity of conveying cylinder 38 is connected to the inner cavity of support cylinder 33 through air pipe 381 so as to drive support plate 391 to slide using air pressure.

[0041] like Figure 7 and8 As shown, a bearing is also embedded in the side wall of the operation box 21 away from the box body 2. One end of the rod is rigidly fitted with the inner cavity of the bearing on the operation box 21, and a first handwheel 376 is fixed at the end of the rod. The first handwheel 376 is located on the outside of the operation box 21, and the rod is rotated by rotating the first handwheel 376.

[0042] The sliding of the support rod is achieved through the stripping rod. Specifically, utilizing the principle of an air pump, during the rotation of the rod, the drive rod moves linearly under the action of the transmission rod. This causes one of the drive discs to slide within the conveying cylinder, supplying air to the support cylinder. As the air inside the support cylinder increases, it pushes the support plate, causing the support rod to move upwards, which in turn moves the cutting toothed ring upwards. Since the cutting blade contacts the cable sheath, stripping can be performed simultaneously during the cutting process. The air supply pipe consists of a main pipe and two branch pipes. One end of the main pipe connects to the conveying cylinder, and one end of each branch pipe connects to the main pipe and the other end connects to the two support cylinders. During the rotation of the rod, the support rods within the two support cylinders move upwards synchronously.

[0043] To further optimize the above technical solution, a second one-way valve is provided on the gas delivery pipe, which allows air to flow only from the delivery cylinder to the support cylinder; a second solenoid valve is provided on the support cylinder, which is opened after peeling to depressurize the support cylinder, and at the same time the elastic restoring force of the support spring is used to drive the support rod to move downward and reset.

[0044] In some other specific embodiments, the transmission rod includes a fixed rod and a hinged rod. One end of the fixed rod is fixed to the middle of one side of the push plate, one end of the hinged rod is hinged to the other end of the fixed rod, and the other end of the hinged rod is hinged to the fixed plate. When the rod rotates, the linear movement of the push rod is achieved through the cooperation of the hinged rod and the fixed rod.

[0045] To further optimize the above technical solution and prevent the cutting tooth ring from disengaging from the first gear due to the up-and-down movement of the cutting tooth ring, the thickness of the cutting tooth ring 34 is greater than the thickness of the first gear 312.

[0046] In this embodiment, the anti-pull assembly 4 includes an anti-pull rod 45, a U-shaped plate 46, a transmission cylinder 41, a push-pull cylinder 42, a rack 43, and a reinforcing gear 44. One end of the anti-pull rod 45 is vertically rotatably connected to the inner wall of the housing 2. The closed end of the U-shaped plate 46 is fixed to the other end of the anti-pull rod 45, and its U-shaped groove corresponds to the through hole 22. The outer walls of the transmission cylinder 41 and the push-pull cylinder 42 are both fixed to the support members, and the outer periphery of another push disk 375 slides against the inner wall of the transmission cylinder 41. One end of the rack 43 is fixed with a sealing disk 431 that slides against the inner wall of the push-pull cylinder 42, and the other end protrudes from the push-pull cylinder 42. The inner cavities of the transmission cylinder 41 and the push-pull cylinder 42 are connected by a transmission pipe 411 to drive the sealing disk 431 to slide using air pressure. The reinforcing gear 44 is fixed to the anti-pull rod 45 and meshes with the rack 43 to drive the U-shaped plate 46 to rotate and limit the cable winding.

[0047] like Figure 13 As shown, the two push discs on the rod are connected to the conveying cylinder and the transmission cylinder, respectively. This means that the anti-pull assembly operates simultaneously while the cable sheath is being stripped. The anti-pull assembly operates on the principle of an air pump. The linear movement of the push discs allows air from the transmission cylinder to be transported to the push-pull cylinder through the transmission pipe. As the air in the push-pull cylinder increases, it pushes the sealing disc, causing the rack to move linearly. During this linear movement, the rack drives the reinforcing gear to rotate. The rotation of the reinforcing gear causes the anti-pull rod and the U-shaped plate to rotate synchronously. Because the U-shaped groove of the U-shaped plate corresponds to the through hole on the box, the cable wraps around the U-shaped plate during rotation, thus limiting the cable and preventing the already connected terminals from being pulled during the stripping process, which could cause the terminals to become loose.

[0048] To further optimize the above technical solution, the correction component 5 includes a correction rod 51, a bidirectional gear 52, and a correction wheel 53; there are two correction rods 51, the bidirectional gear 52 is fixed to one end of the correction rod 51 and the two bidirectional gears 52 mesh with each other so that the two correction wheels 53 rotate in opposite directions; the outer diameter of the correction wheel 53 is smaller than the outer diameter of the bidirectional gear 52; the correction wheel 53 is fixed on the correction rod 51 and corresponds to the top of the U-shaped plate 46; multiple correction wheels 53 can roll against the outer wall of the cable to correct the bent cable.

[0049] To further optimize the above technical solution, the correction assembly 5 also includes a rotating rod 54 and a restoring rod 56; one end of the rotating rod 54 is vertically rotatably connected to the side wall of the housing 2, and the other end is fixed to a restoring cylinder 541; one end of the correction rod 51 away from the bidirectional gear 52 is fixed to a ratchet 511; the ratchet 511 is located inside the restoring cylinder 541 and the inner wall of the restoring cylinder 541 is fixed with a pawl 542 that engages with the ratchet 511; one end of the restoring rod 56 is vertically rotatably connected to the inner wall of the housing 2 and corresponds to the lower part of the rotating rod 54; a restoring gear 57 that meshes with the rack 43 is fixed on the restoring rod 56; the rotating rod 54 and the restoring rod 56 are driven by a sprocket assembly 55.

[0050] like Figure 15 and 16 As shown, the rotating rod 54 is arranged vertically to the rod body, and the side wall of the box body 2 is also embedded with a bearing. One end of the rotating rod 54 passes through the side wall of the box body 2 and the rotating rod 54 is interference-fitted with the bearing on the box body 2. A second handwheel 543 is fixed to one end of the rotating rod 54, and the rotating rod 54 is driven to rotate through the second handwheel 543. The axis of the rotating rod 54 coincides with that of the straightening rod 51. The rotating rod 54 and the straightening rod 51 are connected in the box body 2 through the recovery cylinder 541. The recovery rod 56 is driven by the sprocket set 55.

[0051] Because of the interlocking of the ratchet and pawl, the rotating rod and the straightening rod can only rotate in one direction. When the rack moves linearly and the cable gets tangled on the U-shaped plate, the rack will not drive the rotating rod and the straightening rod to rotate. When the cable needs to be straightened and restored, the second handwheel is turned. The second handwheel drives the restoration rod to rotate under the action of the sprocket set. The restoration gear on the restoration rod drives the rack to move in the opposite direction, so that the cable tangled on the U-shaped plate is untied. At the same time, under the action of the straightening wheel, the cable that was bent due to tangling is restored to a straight state.

[0052] To further optimize the above technical solutions, such as Figure 14 As shown, a third one-way valve 421 is provided at one end of the transmission tube 411 corresponding to the push-pull cylinder 42. The third one-way valve can only allow gas to flow from the transmission tube 41 to the push-pull cylinder 42. A third solenoid valve 422 is provided on the push-pull cylinder 42. When it is necessary to straighten and restore the cable, the third solenoid valve 422 is opened to depressurize the push-pull cylinder 42. After the push-pull cylinder 42 is depressurized, the rotation of the restoration rod 56 drives the restoration gear 57 to drive the rack 43 to reset.

[0053] In other specific embodiments, to ensure the stability of the recovery rod, one end of the recovery rod rotatably abuts against the inner wall of the housing. Specifically, a bearing with an interference fit to the recovery rod is fixed to the side wall of the housing, and the bearing is used to ensure the horizontal degree of freedom of the recovery rod.

[0054] To further optimize the above technical solution, the sprocket assembly 55 includes a driving sprocket 551, a driven sprocket 552, and a chain 553; the driving sprocket 551 is fixed on the rotating rod 54; the driven sprocket 552 is fixed on the restoring rod 56; and the chain 553 connects the driving sprocket 551 and the driven sprocket 552.

[0055] According to a handcart-type switch cabinet of this embodiment, the wiring box in the above technical solution is adopted, and the cabinet body 1 is also included; multiple opening and closing frames 11 are slidably connected on the cabinet body 1, and the multiple opening and closing frames 11 are arranged vertically along the cabinet body 1; a mounting plate 12 is fixed on the top surface of the end of the opening and closing frame 11 away from the cabinet door; multiple electrical components are bolted to the plate surface of the mounting plate 12; there are multiple boxes 2, and the multiple boxes 2 are magnetically attracted to the plate surface of the mounting plate 12 and correspond one-to-one with the multiple electrical components.

[0056] like Figures 1 to 3 As shown, a magnetic plate is fixed on the side wall of the box away from the operating box, and a patch that can be magnetically connected to the magnetic plate is fixed on the surface of the mounting plate.

[0057] The handcart-type switchgear provided in this embodiment solves the problems of inaccurate stripping, easy pulling of cables leading to loosening, and bending caused by clamping in traditional handcart-type switchgear during the cable laying process. By integrating stripping components, anti-pull components, and straightening components, it achieves automatic, precise, and safe cable handling, improving cable laying efficiency and electrical connection reliability, and meeting the requirements of smart grids for intelligent, standardized, and highly safe switching equipment. The stripping component achieves precise circumferential cutting and axial stripping of the cable sheath, ensuring consistent stripping length and no damage to the conductor. Then, the anti-pull component automatically clamps the bottom of the cable during the stripping process to prevent the entire cable from being pulled and avoid loosening of the connected terminals. Subsequently, the straightening component automatically releases the clamp after stripping and straightens the bent parts of the cable, ensuring that the exposed wires are straight and easy to accurately insert into electrical interfaces. Through the above operations, these three parts work together to form an integrated, automated, and rapid cable laying system, providing safety assurance and fundamentally eliminating safety accidents caused by human error or inherent equipment risks. The cabinet adopts a modular pull-out structure and a quick cable routing design, which makes the operation space for trolley entry and exit, component replacement and circuit inspection more open and the path smoother. The time for a single maintenance operation can be reduced by more than 30%, significantly reducing equipment downtime and ensuring the continuous and efficient operation of the power system or industrial production line.

[0058] The wiring operation method for the handcart-type switchgear in this embodiment is as follows: S1. Pass the cable through the through hole in the box from bottom to top.

[0059] S2. Rotate the knob to drive the cutting rod to rotate the cutting tooth ring, which in turn drives the U-shaped toothed plate to move linearly. During the linear movement of the U-shaped toothed plate, the extrusion plate uses the extrusion plate to transport the air in the extrusion cylinder to the cutting cylinder. Under the action of the first one-way valve, the air in the cutting cylinder will not flow back. As the air in the cutting cylinder continues to increase, the cutting rod drives the cutter to slide out of the groove on the inner wall of the ring and slowly contact the surface of the cable sheath. The cutting tooth ring rotates 180°, and the two cutting blades rotate in a ring around the outer circumference of the cable to complete the cutting operation of the cable sheath.

[0060] S3. Rotating the first handwheel drives the rod to rotate. Under the action of the transmission rod, the rod drives the push rod to move one of the push discs linearly. The push disc transports the air in the conveying cylinder to the support cylinder. Under the action of the second one-way valve, the air in the support cylinder will not flow back. As the air in the support cylinder increases, it can drive the support rod to move upward. At this time, it will drive the cutting toothed ring to move upward synchronously. The rotation and upward movement of the cutting toothed ring cause the cutting knife to cut the outer glass of the cable.

[0061] S4. During the rotation of the first handwheel, another pusher disc will move linearly inside the transmission cylinder, thereby delivering the air inside the transmission cylinder to the push-pull cylinder. Under the action of the third one-way valve, the air inside the push-pull cylinder will not flow back. As the air inside the push-pull cylinder continues to increase, it will drive the sealing disc to move linearly with the rack. The linear movement of the rack will drive the reinforcing gear to grab the cable. The reinforcing gear will drive the U-shaped plate to rotate, causing the cable to become entangled.

[0062] S5. After the cable sheath is stripped, open the first solenoid valve to reset the sheath cutting rod and sheath cutting blade, open the second solenoid valve to reset the support rod, and open the third solenoid valve to release pressure from the push-pull cylinder.

[0063] S6. Rotate the second handwheel to drive the rotating rod. The rotating rod drives the straightening rod to rotate under the action of the recovery disc, ratchet, and pawl. At the same time, the sprocket group drives the recovery rod to rotate. The rotation of the recovery rod can reset the rack, thereby untying the cable wrapped around the U-shaped plate. At the same time, the straightening wheel drives the cable to rise. Through the rotation and compression of the two straightening wheels, the cable that was bent due to entanglement is reset to a straight state.
