Description

Technical Field

[0001] This utility model relates to the field of power construction equipment technology, specifically a lifting support frame for power construction. Background Technology

[0002] During power construction work, operators often need to climb to high places to inspect utility poles or distribution boxes. In the past, ladders were usually used to help operators climb to higher places, but ladders have a low safety factor and pose certain safety hazards when operators are inspecting circuits. Therefore, nowadays, power construction lifting support frames are usually used to help operators climb to higher places to work.

[0003] In the prior art, patent publication number CN213834447U discloses a safety lifting device for power construction, including a base, a column, and a lifting platform. A fixed plate is fixedly connected to the inner wall of the inner cavity of the base. An electric hydraulic push rod is fixedly connected below the fixed plate and connected to a movable plate. A fixed frame and a support leg are respectively connected to the bottom of the movable plate. A motor is mounted on the fixed frame, and a sprocket is mounted on the output shaft of the motor. A rotating shaft is mounted on the support leg, and a sprocket and a roller are respectively provided on the rotating shaft. The sprocket is connected to the sprocket via a chain.

[0004] The safety lifting device for power construction has the following disadvantages: it uses two motors to drive the wire ropes on both sides to wind up, thereby moving the lifting platform. However, it is difficult to keep the two motors synchronized during use, resulting in uneven winding of the wire ropes on both sides, which can cause the lifting platform to jam. To address this, we propose a lifting support frame for power construction. Utility Model Content

[0005] The technical problem this utility model aims to solve is to overcome existing defects and provide a lifting support frame for power construction. Through a lifting mechanism, a motor drives a worm gear to rotate, which in turn drives a worm wheel to rotate, causing a rotating rod to rotate, which in turn drives a bevel gear to rotate, which in turn drives a rotating shaft to rotate, causing a winding reel to rotate and thus winding up four sets of wire ropes. This ensures that the winding degree of the four sets of wire ropes is consistent. Simultaneously, the four sets of wire ropes pull the lifting platform, distributing the stress borne by each set of wire ropes, thereby improving the service life of the wire ropes and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting support frame for power construction, comprising a support frame, wherein a movable frame one is slidably connected inside the support frame, a movable frame two is slidably connected inside the movable frame one, a lifting platform is fixedly connected to the lower inside of the movable frame two, a protective groove is fixedly connected to the lower inside of the support frame, and a lifting mechanism is also included.

[0007] The lifting mechanism includes a rotating shaft, bevel gear one, bevel gear two, a worm gear, and a worm. The rotating shaft is rotatably connected to the left and right sides of the support frame. Bevel gear one is fixedly connected to the middle of the rotating shaft. A rotating rod is rotatably connected inside the protective groove. Bevel gear two is symmetrically distributed and fixedly connected to the left and right ends of the rotating rod. Each bevel gear two meshes with bevel gear one on the same side. A worm gear is fixedly connected to the middle of the rotating rod. A worm is rotatably connected inside the protective groove and meshes with the worm gear. Through the lifting mechanism, the motor drives the worm to rotate, which in turn drives the worm gear to rotate, causing the rotating rod to rotate, which in turn drives bevel gear two to rotate, causing bevel gear one to rotate, which in turn drives the rotating shaft to rotate, causing the winding reel to rotate and thus driving the four sets of wire rope one to wind up. This ensures that the winding degree of the four sets of wire rope one is consistent. At the same time, the four sets of wire rope one and wire rope two pull the lifting platform, which can distribute the stress borne by each wire rope one and wire rope two, thereby improving the service life of the wire rope.

[0008] Furthermore, a control switch is provided on the outside of the support frame, and the input terminal of the control switch is electrically connected to an external power source to control the operation of electrical appliances.

[0009] Furthermore, the lifting mechanism also includes a winding reel, a fixing pin, a first steel wire rope, and a fixed pulley. The winding reels are respectively fixedly connected to the front and rear ends of the rotating shaft. The lower sides of the front and rear surfaces of the support frame, the first movable frame, and the second movable frame are all fixedly connected with symmetrically distributed fixing pins. The upper sides of the front and rear surfaces of the support frame and the first movable frame are all fixedly connected with symmetrically distributed fixed pulleys. The outer surface of the winding reel is fixedly connected to the fixing pin on the lower side of the adjacent movable frame on the same side.

The fixing pin on the lower side of the support frame is fixedly connected to the fixing pin on the lower side of the adjacent movable frame on the same side. The middle part of the second steel wire rope passes through the upper side of the fixed pulley on the upper side of the adjacent movable frame on the same side, driving the first movable frame and the second movable frame to move.

[0010] Furthermore, a motor is fixedly connected to the bottom wall of the protective groove, the upper end of the motor's output shaft is fixedly connected to the lower end of the worm gear, and the input end of the motor is electrically connected to an external power source to provide driving force.

[0011] Furthermore, the left and right surfaces of the support frame are rotatably connected with connecting frames that are symmetrically distributed front and back. The end of each connecting frame away from the support frame is threaded with a bolt, and the lower end of each bolt is fixedly connected with a support foot to support the lifting support frame for power construction.

[0012] Furthermore, the support frame has symmetrically distributed support blocks fixedly connected to both the front and rear sides inside, and rubber pads fixedly connected to the upper surface of each support block to support the movable frame.

[0013] Furthermore, the lower left surface of the support frame is fixedly connected with symmetrically distributed casters, and the lower right surface of the support frame is fixedly connected with symmetrically distributed directional casters, which facilitates the movement of the lifting support frame for power construction.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This lifting support frame for power construction has the following advantages:

[0015] The lifting mechanism drives the motor to rotate the worm gear, which in turn rotates the worm wheel, causing the rotating rod to rotate. This, in turn, rotates the bevel gear, which in turn rotates the shaft, causing the winding reel to rotate. This, in turn, drives the four sets of wire ropes to wind up, ensuring that the winding degree of the four sets of wire ropes is consistent. At the same time, the four sets of wire ropes pull the lifting platform, which can distribute the stress borne by each set of wire ropes, thereby improving the service life of the wire ropes.

The rotating bolts... 3. Rotate bolt 3, move bolt 3 downward, drive support leg 4 downward and close to the ground, thereby supporting support frame 1. Support blocks 11 are fixedly connected to the front and rear sides of the support frame 1. Rubber pads are fixedly connected to the upper surface of support blocks 11. When the power construction lifting support frame is not in use, support blocks 11 support the movable frame 5. Universal wheels 13 are fixedly connected to the left side of the lower surface of support frame 1. Directional wheels 12 are fixedly connected to the right side of the lower surface of support frame 1. Under the action of directional wheels 12 and universal wheels 13, the support frame 1 is pushed to a specific position. A control switch 10 is provided on the outside of support frame 1. The input end of control switch 10 is electrically connected to an external power source. It also includes lifting mechanism 8.

[0023] The lifting mechanism includes a rotating shaft 85, a first bevel gear 86, a second bevel gear 87, a worm gear 88, and a worm 89. The rotating shaft 85 is rotatably connected to the left and right sides of the support frame 1. A first bevel gear 86 is fixedly connected to the middle of each rotating shaft 85. A rotating rod is rotatably connected inside the protective groove. Symmetrically distributed second bevel gears 87 are fixedly connected to both ends of the rotating rod, and each second bevel gear 87 meshes with a first bevel gear 86 on the same side. A worm gear 88 is fixedly connected to the middle of the rotating rod, and a worm 89 is rotatably connected inside the protective groove, meshing with the worm gear 88. The lifting mechanism also includes a winding reel. 81, 82, 83, and 84 are fixedly connected to the front and rear ends of the rotating shaft 85, respectively. Fixed pins 82 are symmetrically distributed on the lower sides of the front and rear surfaces of the support frame 1, movable frame 5, and movable frame 6. Fixed pulleys 84 are symmetrically distributed on the upper sides of the front and rear surfaces of the support frame 1 and movable frame 5. A wire rope 83 is fixedly connected between the outer surface of the take-up reel 81 and the fixed pin 82 on the lower side of the adjacent movable frame 5 on the same side.

The middle part of the steel wire rope 2 passes through the upper side of the fixed pulley 84 on the upper side of the adjacent movable frame 5 on the same side. The bottom wall of the protective groove is fixedly connected with a motor 9. The upper end of the output shaft of the motor 9 is fixedly connected to the lower end of the worm gear 89. The input end of the motor 9 is electrically connected to an external power source. At this time, the control switch 10 is operated to start the motor 9. The output shaft of the motor 9 rotates, driving the worm gear 89 to rotate, causing the worm wheel 88 to rotate, driving the rotating rod to rotate, causing the bevel gear 87 to rotate, driving the bevel gear 88 to rotate, driving ... Gear 86 rotates, causing shaft 85 to rotate, which in turn drives take-up reel 81 to rotate. This causes wire rope 83 to wind around the outer surface of take-up reel 81. At this time, wire rope 83 drives the fixing pin 82 on the lower side of movable frame 5 to move upward, causing movable frame 5 to move upward. This causes the fixed pulley 84 on the upper side of movable frame 5 to move upward. At this time, the length of wire rope 2 between the fixing pin 82 on the lower side of movable frame 2 6 and the fixed pulley 84 on the upper side of movable frame 5 decreases, thereby driving the fixing pin 82 on the lower side of movable frame 2 6 to move upward, causing movable frame 2 6 to move upward, and driving lifting platform 7 to move upward.

[0024] The working principle of the lifting support frame for power construction provided by this utility model is as follows: When using the lifting support frame for power construction, the support frame 1 is pushed to a specific position by the action of the directional wheel 12 and the universal wheel 13. At this time, the bolt 3 is rotated, causing the bolt 3 to rotate downward, which drives the support leg 4 to move downward and close to the ground, thereby supporting the support frame 1. At this time, the control switch 10 is operated to start the motor 9. The output shaft of the motor 9 rotates, which drives the worm gear 89 to rotate, causing the worm wheel 88 to rotate, which drives the rotating rod to rotate, causing the second bevel gear 87 to rotate, which drives the first bevel gear 86 to rotate. The rotation causes the shaft 85 to rotate, which in turn drives the winding reel 81 to rotate, thereby causing the wire rope 83 to wind around the outer surface of the winding reel 81. At this time, the wire rope 83 drives the fixing pin 82 on the lower side of the movable frame 5 to move upward, causing the movable frame 5 to move upward, which in turn drives the fixed pulley 84 on the upper side of the movable frame 5 to move upward. At this time, the length of the wire rope 82 between the fixing pin 82 on the lower side of the movable frame 6 and the fixed pulley 84 on the upper side of the movable frame 5 decreases, thereby driving the fixing pin 82 on the lower side of the movable frame 6 to move upward, causing the movable frame 6 to move upward, which in turn drives the lifting platform 7 to move upward.

[0025] It is worth noting that the motor 9 disclosed in the above embodiments is Y2-200L-4, and the control switch 10 is provided with a control button corresponding to the motor 9 and used to control its switching.
