Description

Technical Field

[0001] The present application relates to the field of auxiliary maintenance tools, and in particular to a lifting device for auxiliary maintenance. Background Art

[0002] At present, old equipment needs to be dismantled and repaired at the construction site of water conservancy projects. Since there are many large and heavy equipment in the related equipment of water conservancy projects, corresponding handling devices and lifting devices are often required to facilitate operators to operate the water conservancy equipment.

[0003] One of the most commonly used auxiliary disassembly devices on construction sites is the mobile gantry. The mobile gantry usually consists of a base and an upper beam. The beam is usually equipped with a cable winder or a manual hoist to facilitate operators to lift heavier parts, and the mobile gantry is moved by the wheels under the mobile base.

[0004] With regard to the above-mentioned related technologies, when repairing the bottom of the hoisted parts, the operators need to squat under the parts, or reach into the parts from the side and bottom to grope for repairs and maintenance. When the parts are large, the operating space and vision between the bottom of the parts and the ground will be worse, making the maintenance process more difficult and inconvenient for the on-site operators. Utility Model Content

[0005] In order to facilitate operators to flip and move parts to obtain more operating space, and thus make it easier for operators to maintain and service parts, the present application provides a lifting device for auxiliary maintenance.

[0006] This application provides a hoisting device for auxiliary maintenance, which adopts the following technical solutions:

[0007] A lifting device for auxiliary maintenance includes a frame, a crossbeam is provided on the upper side of the frame, a main lifting assembly for lifting parts is provided on the lower side of the crossbeam, the lifting length of the main lifting assembly is adjustable, the crossbeam is provided with a mounting seat, a first cable reel and a first auxiliary lifting rope are provided below the mounting seat, one end of the first auxiliary lifting rope is fixedly connected to the first cable reel, and the first cable reel is located on one side of the main lifting assembly.

[0008] By adopting the above technical solution, the operator lifts the part through the main lifting assembly, connects the first auxiliary lifting rope to one end of the part, and after completing the connection, adjusts the length of the first auxiliary lifting rope by reeling and unreeling through the first cable winding machine, thereby realizing the rotation of the angle of the part, making it easier for the operator to repair and adjust the bottom surface of the part.

[0009] Optionally, a second cable reel and a second auxiliary lifting rope are provided below the mounting seat, one end of the second auxiliary lifting rope is fixedly connected to the second cable reel, and the second cable reel is located on a side of the main lifting assembly away from the first cable reel.

[0010] By adopting the above technical solution, after the main lifting assembly completes the lifting of the part and adjusts the length of the first auxiliary lifting rope to adjust the angle of the part, the second cable reel is reeled in to retract the second lifting rope, and the other end of the part is limited by the second lifting rope, thereby effectively achieving auxiliary positioning of the part.

[0011] Optionally, the mounting seat is provided with a roller, and a slide groove adapted to the roller is provided in the length direction of the beam. The mounting seat is divided into a left half and a right half, the first cable winder is located in the left half, and the second cable winder is located in the right half.

[0012] By adopting the above technical solution, the two sections of the mounting seat can be moved independently. The left half can be moved independently to move the position of the first cable winder, and the right half can be moved to move the position of the second cable winder, thereby enabling effective lifting and rotation of parts with different lengths and different center of gravity positions.

[0013] Optionally, motors are provided at both ends of the upper side of the beam, and the motors are axially connected to a screw rod. The length direction of the screw rod is the same as the length direction of the beam. The left half and the right half are both provided with threaded holes adapted to the screw rod, and the threaded holes are rotatably connected to the screw rod.

[0014] By adopting the above technical solution, the operator controls the motors corresponding to the left and right halves to rotate the screw rod and adjust the positions of the left and right halves, further simplifying the difficulty of moving the left and right halves for the operator.

[0015] Optionally, an auxiliary bracket is provided on the upper side of the beam, the auxiliary bracket is located in the middle of the beam, two bearings are provided on both sides of the auxiliary bracket, the axial direction of the bearing is the same as the length direction of the beam, and a mounting portion is provided at the end of the screw rod, which is adapted to the inner wall of the bearing.

[0016] By adopting the above technical solution, the end of the screw rod away from the motor is the free end, that is, the mounting part. By placing the mounting part in the bearing of the auxiliary bracket, the free end is effectively restricted, thereby effectively realizing the rotational stability of the screw rod and achieving stable movement of the mounting seat.

[0017] Optionally, the frame includes a column and a base, the column is used to connect the beam and the base, a moving component for moving the frame is provided under the base, a boss is provided on the upper side of the base, the column is provided with a groove adapted to the boss, a limiting groove is provided on the outer edge of the boss, and a limiting block extending into the limiting groove is provided on the inner side of the groove, and the boss and the groove are rotatably connected.

[0018] By adopting the above technical solution, when the operator pushes the device, the moving assembly drives the entire device to move, and the rotating base facilitates the direction of the entire device to be turned, so as to pass through a relatively narrow space and extend into the limit groove through the limit block, thereby preventing the boss from falling out of the groove when carrying the lifting device.

[0019] Optionally, the moving assembly includes a crawler track, which is rotatably connected to the base. When an operator pushes the device, the crawler track rotates to move the device as a whole.

[0020] By adopting the above technical solution, the crawler track has better passability on poor road surfaces, making it easier for operators to drag the lifting device at the construction site.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The operator lifts the part through the main lifting assembly and connects the first auxiliary lifting rope to one end of the part. After the connection is completed, the operator adjusts the length of the first auxiliary lifting rope by reeling and unreeling the first cable winder, thereby rotating the part to facilitate the operator to repair and adjust the bottom surface of the part.

[0023] 2. After the main lifting assembly completes the lifting of the part and adjusts the length of the first auxiliary lifting rope to adjust the angle of the part, the second cable reel is reeled in to retract the second lifting rope, and the other end of the part is limited by the second lifting rope, thereby effectively achieving auxiliary positioning of the part.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0030] An embodiment of the present application discloses a hoisting device for auxiliary maintenance.

[0031] Reference Figures 1 to 4 A lifting device for auxiliary maintenance includes a frame 1, a crossbeam 11 is provided on the upper side of the frame 1, and a main lifting assembly 3 for lifting a part 101 is provided on the lower side of the crossbeam 11. The lifting length of the main lifting assembly 3 is adjustable, and the crossbeam 11 is provided with a mounting seat 4. A first cable reel 411 and a first auxiliary lifting rope 412 are provided below the mounting seat 4. One end of the first auxiliary lifting rope 412 is fixedly connected to the first cable reel 411, and the first cable reel 411 is located on one side of the main lifting assembly 3. The operator lifts the part 101 through the main lifting assembly 3 and connects the first auxiliary lifting rope 412 to one end of the part 101. After the connection is completed, the operator adjusts the length of the first auxiliary lifting rope 412 by rewinding and unreeling the first cable reel 411, thereby rotating the angle of the part 101, making it easier for the operator to repair and adjust the bottom surface of the part 101.

[0032] The main hoist assembly 3 mentioned herein can be a hand chain hoist, an electric hoist, or other similar structures. In this embodiment, the main hoist assembly 3 is composed of a winch driven by a hoist and a hoist rope. The above-mentioned contents are mature existing technologies that are well-known to those skilled in the art, so the main hoist assembly 3 will not be described in detail herein.

[0033] When hoisting a part 101 whose center of gravity is not at the center of the object, if the part 101 is hoisted and the angle is adjusted only by the first auxiliary lifting rope 412 and the main lifting assembly 3, the lifting of the part 101 may be unstable, which may lead to a safety accident. In order to solve this problem, a second cable winder 421 and a second auxiliary lifting rope 422 are provided under the mounting seat 4. One end of the second auxiliary lifting rope 422 is fixedly connected to the second cable winder 421. The second cable winder 421 is located on the side of the main lifting assembly 3 away from the first cable winder 411. After the main lifting assembly 3 completes the hoisting of the part 101 and adjusts the length of the first auxiliary lifting rope 412 to adjust the angle of the part 101, the second cable winder 421 is retracted to retract the second lifting rope, and the other end of the part 101 is limited by the second lifting rope, thereby realizing auxiliary positioning of the part 101.

[0034] When hoisting part 101 through three lifting points, the best choices are the middle and two sides, and the lifting points should be distributed as evenly as possible throughout the entire part 101 to facilitate the hoisting of parts 101 of different lengths. The mounting seat 4 is equipped with rollers, and the crossbeam 11 is provided with a slide groove adapted to the rollers along the length direction. The mounting seat 4 is divided into a left half 41 and a right half 42. The first cable winder 411 is located in the left half 41, and the second cable winder 421 is located in the right half 42. The two sections of the mounting seat can be moved independently. Moving the left half 41 independently can move the position of the first cable winder 411, and moving the right half 42 can move the position of the second cable winder 421. This allows for effective hoisting and rotation of parts 101 of different lengths and different center of gravity positions.

[0035] To simplify the operator's movement of the left and right halves 41, 42, motors 2 are provided at both ends of the upper side of the crossbeam 11. A screw rod 21 is axially connected to the motor 2. The length of the screw rod 21 is the same as that of the crossbeam 11. Both the left and right halves 41, 42 are provided with threaded holes adapted to fit the screw rods 21. The threaded holes are rotatably connected to the screw rods 21. The operator controls the corresponding motors 2 on the left and right halves 41, 42 to rotate the screw rods 21 and thereby adjust the positions of the left and right halves 41, 42, further simplifying the operator's movement of the left and right halves 41, 42.

[0036] An auxiliary bracket is installed on the upper side of the crossbeam 11, located in the middle of the crossbeam 11. Two bearings are installed on either side of the auxiliary bracket, with the bearing axial direction aligned with the length of the crossbeam 11. A mounting portion is provided at the end of the screw rod 21, which fits into the inner wall of the bearing. The end of the screw rod 21 away from the motor 2 is the free end, i.e., the mounting portion. By placing the mounting portion in the bearing of the auxiliary bracket, the free end is effectively restricted, thereby effectively achieving the rotational stability of the screw rod 21 and the stable movement of the mounting seat.

[0037] The space on the construction site is relatively limited. In order to further improve the flexibility of this device, the frame 1 includes a column 12 and a base 13. The column 12 is used to connect the crossbeam 11 and the base 13. A moving component for moving the frame 1 is provided below the base 13. A boss 132 is provided on the upper side of the base 13. The column 12 is provided with a groove adapted to the boss 132. A limiting groove is provided on the outer edge of the boss 132. A limiting block is provided on the inner side of the groove to extend into the limiting groove. The boss 132 is rotatably connected to the groove. When the operator pushes the device, the moving component drives the entire device to move. By rotating the base 13, the direction of the entire device can be turned to pass through a relatively narrow space. The limiting block extends into the limiting groove, thereby preventing the boss 132 from falling out of the groove when the lifting device is transported.

[0038] A locking structure may also be optionally added to stabilize and lock the base 13 and the column 12 .

[0039] There is a high possibility that there is accumulated water on the ground at the construction site of a water conservancy project, which will produce mud after mixing with the soil, thereby affecting the movement of the device. In addition, the weight of the device plus the hoisting parts 101 is relatively large, which further increases the possibility of the hoisting device sinking into the soil. In order to facilitate the movement and normal use of the hoisting device on the bottom surface mixed with mud and water. The moving component includes a crawler 131, and the crawler 131 is rotatably connected to the base 13. When the operator pushes the device, the crawler 131 rotates to bring the device into motion as a whole. The crawler 131 has good passability for poor road conditions, which makes it convenient for the operator to drag the hoisting device at the construction site.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
