According to the transportation equipment for power transformer production, when a power transformer is transported to climb a slope, a leveling ball can be driven to rotate through the gravity borne by a balancing weight, so that the leveling ball drives a placing plate and objects on the placing plate to be in a horizontal state all the time, and the objects on the placing plate are prevented from falling off due to the fact that the inclination angle is too large; the phenomenon that the articles fall off from the placing plate is avoided; when the placing plate is automatically leveled, a first hinge block, a first sliding block and a second hinge block are matched to pull a second sliding block to slide towards the center direction of the placing plate, so that the second sliding block pushes a first hinge rod to drive a hinge plate to rise, the power transformer is pushed towards the center of the placing plate, and the situation that the angle is suddenly adjusted during uphill is avoided; and the power transformer slides downwards to fall under the influence of inertia.

Description

Technical Field

[0001] The invention relates to the technical field of transportation equipment for power transformer production, and in particular to transportation equipment for power transformer production. Background Art

[0002] Power transformers are key equipment in power systems, used to convert voltage or current proportionally to achieve measurement, protection and control. Their transportation after production is crucial and requires special equipment. With the development of the power industry, the demand for transformers has increased and the transportation distance has increased. Efficient transportation equipment is needed to improve logistics efficiency. At the same time, the power system has strict requirements on the quality and reliability of transformers. Any transportation damage may lead to power accidents. Therefore, the development of special transportation equipment to ensure transportation safety and improve transportation efficiency is of great significance to the production and application of power transformers.

[0003] Patent publication number CN214610047U is a conveying device for assembling current transformers, including a supporting base and a conveying platform, a support plate is arranged between the supporting base and the conveying platform, the left and right ends of the upper surface of the support plate are fixedly connected to the conveying platform through pillars, and clamps are symmetrically arranged on the left and right sides of the upper surface of the conveying platform, the clamps are fixedly connected to the conveying platform, and inclined clamp seats are symmetrically arranged between the clamps, and the inclined clamp seats are slidably connected to the conveying platform. The current transformer to be conveyed is placed between the clamps and the inclined clamp seats, and is rotated by a driving motor. The driving motor drives the screw to rotate through bevel gears one and two, and the nuts on the left and right sides push the receiving rod to move upward through the push rod, and the receiving rod drives the inclined clamp seat to move toward the clamp plate through the left and right support rods and rollers, thereby clamping the current transformer on the surface of the conveying platform to prevent it from falling during transportation, and the transportation stability is higher.

[0004] However, the above-mentioned transportation equipment only focuses on protecting the sides of the power transformer, and its protection method is relatively simple and unitary. Usually, only some basic enclosure structures are set on the sides of the equipment. If it encounters a slope or other terrain, when the vehicle is driving on the slope, the body of the vehicle tilts, and the power transformer is very likely to shift its center of gravity and flip out from the top of the equipment along the tilt angle, and eventually fall to the ground and be damaged.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the visual sensor 8 detects an obstacle in front, it transmits an electrical signal to the alarm 9, and an alarm is sounded through the alarm 9, which sends an alarm to the staff who pushes the transportation equipment from the rear, informing the staff to push it carefully.

[0029] Among them, the leveling structure 5 includes a leveling ball 51, a counterweight 52, a placement plate 53, a limiting ball 54, a first spring 55, a movable block 56, a first hinge block 57, a first slider 58, a second hinge block 59, a second slider 510, a first hinge rod 511 and a hinge plate 512. The leveling ball 51 passes through the mounting plate 4 and is rotatably connected at the penetration point. A rope is fixed to the outer wall of the leveling ball 51, and a counterweight 52 is fixed to the end of the rope away from the leveling ball 51. When the push handle 3 is pushed uphill, the supporting mechanism 1 drives the mounting plate 4 to tilt, and the counterweight 52 is always in a vertical state due to the influence of gravity. The counterweight 52 drives the leveling ball 51 to rotate, and a placement plate 53 is fixed to the side of the outer wall of the leveling ball 51 away from the counterweight 52. The rotation of the leveling ball 51 causes the placement plate 53 to rotate relative to the When adjusting the angle of the mounting plate 4, a limiting ball 54 passes through the placement plate 53, and the penetration is rotatably connected. The limiting ball 54 rotates at the penetration. Four groups of limiting balls 54 are provided, which respectively pass through the four corners of the placement plate 53. A first spring 55 is fixed to the outer wall of the limiting ball 54. When the limiting ball 54 rotates at the penetration, the first spring 55 above the leveling ball 51 is compressed, and the first spring 55 below the leveling ball 51 is stretched at the same time. A movable block 56 is fixed to one end of the first spring 55 away from the limiting ball 54. The bottom surface of the movable block 56 is slidably connected to the placement plate 53. When the first spring 55 is stretched or compressed, it will drive the movable block 56 to slide. When the movable block 56 slides, it cooperates with the first spring 55 and the limiting ball 54 to limit the four corners of the placement plate 53 to the same line, so as to avoid placing The placement plate 53 is driven to rotate by the leveling ball 51 when adjusting the angle. The bottom surface of the placement plate 53 is hinged with a first hinge block 57. When the placement plate 53 adjusts its angle, the first hinge block 57 is driven to rotate. The end of the first hinge block 57 away from the placement plate 53 is hinged with a first slider 58. The first slider 58 penetrates the mounting plate 4 and is slidably connected at the penetration. The first hinge block 57 rotates to push the first slider 58 to slide in a direction away from the center of the placement plate 53. The upper end of the first slider 58 is hinged with a second hinge block 59. When the first slider 58 slides, the second hinge block 59 is driven to rotate. The end of the second hinge block 59 away from the first slider 58 is hinged with a second slider 510. Two groups of the second hinge block 59 and the second slider 510 are provided. The second slider 510 penetrates the placement plate 5 3, and the penetration is slidably connected. When the second hinge block 59 rotates, it pulls the second slider 510 to make the second slider 510 slide toward the center of the placement plate 53. The side wall of the second slider 510 is hinged with a first hinge rod 511. The second slider 510 pushes the first hinge rod 511 to rotate. The placement plate 53 is provided with a groove, and a cross bar is fixed at the groove. The cross bar penetrates the hinge plate 512 and is rotatably connected at the penetration. The end of the first hinge rod 511 away from the second slider 510 is hinged to the side wall of the hinge plate 512 away from one end of the cross rod. When the first hinge rod 511 rotates, it drives the hinge plate 512 to rise at its hinged end, and pushes the power transformer above the placement plate 53 toward the center of the placement plate 53. The leveling structure 5 can be used when the power transformer is transported to climb a slope.The gravity exerted on the counterweight block 52 drives the leveling ball 51 to rotate, so that the leveling ball 51 drives the placement plate 53 to be in a horizontal state, preventing the objects on the placement plate 53 from falling off the placement plate 53 due to excessive tilt angle. At the same time, the limiting ball 54, the first spring 55 and the movable block 56 are used to limit the placement plate 53, so as to prevent the placement plate 53 from rotating during automatic leveling and throwing out the power transformer. When the placement plate 53 is automatically leveled, the first hinge block 57, the first slider 58 and the second hinge block 59 are used to pull the second slider 510 to slide toward the center of the placement plate 53, so that the second slider 510 pushes the first hinge rod 511 to drive the hinge plate 512 to rise, and pushes the power transformer toward the center of the placement plate 53, so as to avoid the power transformer sliding down and falling due to inertia when the angle is suddenly adjusted when going uphill.

[0030] When this embodiment is working: when the push handle 3 is pushed uphill, the support mechanism 1 drives the mounting plate 4 to tilt, and the counterweight block 52 is always in a vertical state due to the influence of gravity. The counterweight block 52 drives the leveling ball 51 to rotate, so that the placement plate 53 adjusts its angle relative to the mounting plate 4. The placement plate 53 is always in a horizontal state. When the placement plate 53 automatically adjusts its angle relative to the mounting plate 4, the limiting ball 54 rotates at the penetration point, compressing the first spring 55 above the leveling ball 51, and at the same time stretching the first spring 55 below the leveling ball 51, driving the movable block 56 to slide, and limiting the placement plate 53. When the placement plate 53 adjusts its angle, it drives the first hinge block 57 to rotate. The first hinge block 57 rotates to push the first slider 58 to slide in a direction away from the center of the placement plate 53. When the first slider 58 slides, it drives the second hinge block 57 to rotate. The connecting block 59 rotates, and when the second hinge block 59 rotates, it pulls the second slider 510 to make the second slider 510 slide toward the center of the placement plate 53, and the second slider 510 pushes the first hinge rod 511 to rotate. When the first hinge rod 511 rotates, it drives the hinge plate 512 to rise at one end thereof, and pushes the power transformer above the placement plate 53 toward the center of the placement plate 53. When the climbing is completed and the vehicle returns to the flat ground, the counterweight block 52 drives the leveling ball 51 to rotate, and the elastic force of the first spring 55 drives the placement plate 53 to return to a parallel state relative to the mounting plate 4. At the same time, the placement plate 53 cooperates with the first hinge block 57, the first slider 58 and the second hinge block 59 to drive the second slider 510 back to its original position, and the second slider 510 drives the first hinge rod 511 to pull the hinge plate 512, so that the hinge plate 512 is lowered.

Since the length of the second hinge rod 61 remains unchanged, when the placement plate 53 rotates, the second hinge rod 61 rotates to push the first clamping plate 62 to slide toward the center of the placement plate 53. The upper surface of the first clamping plate 62 is hinged with a third hinge rod 63. When the first clamping plate 62 slides toward the center, it drives the third hinge rod 63 to rotate. The end of the third hinge rod 63 away from the first clamping plate 62 is hinged with a second clamping plate 64. The third hinge rod 63 drives the second clamping plate 64 to slide toward the center of the placement plate 53. The first clamping plate 62 and the second clamping plate 64 are respectively provided with two groups, and are adjacent to each other to form a quadrilateral. The clamps on the four sides are tightened to clamp the power transformer. The two ends of the first clamping plate 62 pass through the second clamping plate 64 and pass through The outer wall of the second clamping plate 64 passes through the sliding plate 65 and is slidably connected at the penetration point. A push block 66 passes through the second clamping plate 64 and is slidably connected at the penetration point. When the first clamping plate 62 slides toward the center of the placement plate 53, the push block 66 is pushed to slide toward the center of the second clamping plate 64. The push block 66 pushes the sliding plate 65 to slide upward. The upper surface of the second clamping plate 64 passes through the limiting plate 67 and is slidably connected at the penetration point. When the sliding plate 65 slides upward, it passes through the groove of the limiting plate 67, so that the limiting plate 67 slides along the inclined surface of its inner wall in the direction of the second clamping plate 64.

When the device climbs a slope, the stabilizing structure 6 can drive the second hinged rod 61 to rotate through the automatic leveling of the placement plate 53. When the second hinged rod 61 rotates, it pushes the first clamping plate 62, and cooperates with the third hinged rod 63 to drive the second clamping plate 64 to shrink, so as to clamp and protect the power transformer on all four sides to prevent the power transformer from sliding around on the placement plate 53 due to bumps caused by uneven ground during transportation, causing the power transformer to slip and cause damage; while clamping the power transformer, cooperate with the push block 66 and the sliding plate 65 to push the limit plate 67 to expand, and buckle the power transformer from above to prevent the power transformer from being shaken out due to large bumps, causing the power transformer to fall.

[0032] The buffer structure 7 includes a top rod 71, a fixed block 72 and a third spring 73. The top rod 71 passes through the mounting plate 4 and is slidably connected at the penetration point. The upper end of the top rod 71 fits with the placement plate 53. When the device is pushed downhill, the placement plate 53 pushes the top rod 71 to slide downward. The bottom surface of the top rod 71 is fixed with a fixed block 72. The fixed block 72 passes through the bottom plate of the supporting mechanism 1 and is slidably connected at the penetration point. When the top rod 71 slides downward, the fixed block 72 is driven to slide downward together. The bottom surface of the fixed block 72 is fixed with rubber. The fixed block 72 slides downward until it fits the ground, so that the rubber on the bottom surface of the fixed block 72 The third spring 73 is fixed to the upper surface of the fixed block 72 to rub against the ground. The end of the third spring 73 away from the fixed block 72 is fixedly connected to the bottom surface of the mounting plate 4. When the fixed block 72 slides downward, the third spring 73 is stretched. When the device is pushed downhill, the buffer structure 7 can push the top rod 71 to slide downward through the automatic leveling of the placement plate 53, and cooperate with the support of the fixed block 72 to make the rubber on the bottom surface of the fixed block 72 rub against the bottom surface. The friction force is used to reduce the acceleration of the device when going downhill, so as to buffer the device and prevent the power transformer from being thrown away due to inertia at an excessively high speed during transportation.

[0033] When the present embodiment is working, when the device is pushed to climb a slope, the placement plate 53 rotates to reduce the distance between the first clamping plate 62 and the mounting plate 4. Since the length of the second hinged rod 61 remains unchanged, when the placement plate 53 rotates, the second hinged rod 61 rotates to push the first clamping plate 62 to slide toward the center of the placement plate 53. When the first clamping plate 62 slides toward the center, it drives the third hinged rod 63 to rotate. The third hinged rod 63 drives the second clamping plate 64 to slide toward the center of the placement plate 53. The clamping plates on all four sides are tightened to clamp the power transformer. When the first clamping plate 62 slides toward the center of the placement plate 53, it pushes the push block 66 to slide toward the center of the second clamping plate 64. The push block 66 pushes the sliding plate 65 to slide upward. When the sliding plate 65 slides upward, it passes through the limit The groove of the positioning plate 67 causes the limiting plate 67 to slide along the inclined surface of its inner wall toward the second clamping plate 64, and at the same time compresses the second spring 68, so that the limiting plate 67 slides toward the center of the placing plate 53 to limit the power transformer at the top. When the climbing is completed, the placing plate 53 is horizontal relative to the mounting plate 4, and the second hinged rod 61 pulls the first clamping plate 62 back to its original position. The first clamping plate 62 drives the third hinged rod 63 to rotate, pulling the second clamping plate 64 back to its original position. At this time, the push block 66 is no longer pushed by the first clamping plate 62, and the sliding plate 65 is no longer pushed by the push block 66. It slides downward under the influence of gravity, pushing the push block 66 to slide to both sides. At the same time, the limiting plate 67 is affected by the elastic force of the second spring 68, away from the second clamping plate 64, so that the limiting plate 67 is retracted.

[0034] When the device is pushed downhill, the counterweight block 52 drives the leveling ball 51 to rotate in the opposite direction, and the placement plate 53 also rotates in the opposite direction. The placement plate 53 pushes the top rod 71 to slide downward. When the top rod 71 slides downward, it drives the fixed block 72 to slide downward as well. When the fixed block 72 slides downward, the third spring 73 is stretched, and the fixed block 72 slides downward until it fits the ground, so that the rubber on the bottom of the fixed block 72 rubs against the ground. After returning to the flat ground, the top rod 71 is no longer pushed by the placement plate 53, and the third spring 73 pulls the fixed block 72 to slide upward, so that the rubber is away from the ground.
