Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a steel cage lifting device. Background Art

[0002] A crane is a multi-action lifting machine capable of vertically lifting and horizontally transporting heavy objects within a certain range. It is also known as an overhead crane, overhead crane, or crane. To ensure the rebar cage can be smoothly placed in the pile hole, it must be hoisted with the aid of a crane. Existing cage hoisting methods often utilize a three-point lifting method. The main hoist hoists the rebar horizontally, while auxiliary hoists lift the cage at two points, one-third and two-thirds of the way up. After lifting, the cage is flipped mid-air, the auxiliary hoist releases its hook, and the main hoist hooks upright the cage and hoist it into the pile hole.

[0003] When the auxiliary hoist used in the existing steel cage hoisting is hoisted, the hoisting hook and the hoisting rope at the top of the steel cage form a triangular structure, and the angle between the two hooks of the auxiliary hoist is not greater than 60 degrees; the extension length of the wire rope in the above method cannot be flexibly adjusted, such as Figure 4 As shown in the figure, if the steel cage to be lifted is long and a fixed-length lifting rope is used, the lifting point is too centered on the steel cage, and the two free ends of the steel cage are prone to excessive shaking; Figure 5 As shown, if the steel cage to be lifted is small and the length of the lifting rope cannot be adjusted, the torque of the lifting rope relative to the lifting point of the steel cage is too long, and the lifting wire rope is prone to shaking, which in turn causes the steel cage to shake. Therefore, it is particularly necessary to propose a steel cage lifting device that can flexibly adjust the distance between the lifting point and the wire rope. Utility Model Content

[0025] The following is a combination of specific implementation cases and attached Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0026] The extension length of the wire rope of the existing steel cage crane cannot be flexibly adjusted, which causes the steel cage to shake easily during the lifting process. Figure 1-3As shown, a steel cage lifting device is proposed, including a crane 1, which includes a main hoist 101 and an auxiliary hoist 102. The steel cage is lifted in a three-point lifting manner. The main hoist 101 uses a crane to lift the steel cage horizontally, and the auxiliary hoist 102 lifts the steel cage at two points. After lifting, it flips in the air, and the auxiliary hoist 102 releases the hook. The main hoist 101 uprights the steel cage and lifts it into the pile hole. The main hoist 101 and the auxiliary hoist 102 are arranged opposite to each other on the left and right. The output end of the main hoist 101 is provided with a first lifting part 2, and the output end of the auxiliary hoist 102 is provided with a second lifting part 3. The lifting effects of the main lifting point and the auxiliary lifting point are respectively realized by the first lifting part 2 and the second lifting part 3. The bottom end of the second lifting part 3 is hooked with a lifting ring 17, and the bottom end of the lifting ring 17 is installed with a fixing seat 4. The hooking ring 17 and the fixing seat 4 at the bottom are lifted and lowered synchronously. The inner cavity of the fixing seat 4 is provided with a distance adjusting mechanism. The sliding sleeve on the outer wall of the distance adjusting mechanism is provided with a lifting rope 15. The distance adjusting mechanism is used to adjust the length of the two free ends of the lifting rope 15. The two free ends of the lifting rope 15 are respectively installed with buckles 16. The buckles 16 realize the connection between the lifting rope 15 and the steel cage, so as to realize the second lifting part 3 to drive the two free ends of the lifting rope 15 to be connected with the steel cage with the help of the buckles 16. The two buckles 16 are respectively hooked with the steel cage 18, and the two buckles 16 are respectively hooked at 1 / 3 and 2 / 3 of the steel cage 18. The buckles 16 are used to realize the lifting of the two free ends of the lifting rope 15 in the center of the top of the steel cage 18; the distance adjusting mechanism includes a driving part and a moving part. The driving part is connected to the moving part, and the driving part prompts the moving part to move in the corresponding direction to achieve the adjustment of the extension length of the lifting rope 15; the driving part includes a first slide groove 5 opened in the horizontal direction on the rear side of the inner wall of the fixed seat 4, and the driving part also includes a mounting plate 8 installed on the right side wall of the fixed seat 4, and also includes a motor 9 installed on the top of the mounting plate 8. The motor 9 is a forward and reverse motor, and its output end can rotate forward or reverse according to usage requirements. The output end of the motor 9 is connected to one end of the screw 6 through a coupling, and the other end of the screw 6 is rotatably connected to the left inner wall of the first slide groove 5 through a bearing. The screw 6 is driven by the motor 9 to rotate forward or reverse. The first slider 7 is symmetrically screwed on the left and right sides of the outer wall of the screw 6. The threads on the left and right sides of the wall are set in opposite and symmetrical directions. The rotating screw 6 can drive the two first sliders 7 to move toward the middle or outward respectively; the moving part includes a connecting block 13 installed on the front side wall of each first slider 7, and the front side of the connecting block 13 is rotatably connected to a roller 14 through a bearing. A groove is opened in the circumference of the outer wall of the roller 14, and the lifting rope 15 is slidably hung on the outer wall groove of the two rollers 14. When the first slider 7 moves, it can drive the connecting block 13 and the roller 14 to move synchronously. When the two rollers 14 move synchronously inward, the distance between the two rollers 14 becomes smaller, and the length of the two free ends of the lifting rope 15 on the outer wall of the two rollers 14 extending downward becomes longer, and conversely, the length of the two free ends of the lifting rope 15 extending downward becomes shorter.

[0027] In addition, see Figure 3 As shown, a limiting component is provided on the front side of the inner cavity of the fixed seat 4, and the limiting component includes a second slide groove 10 opened in the horizontal direction on the front side of the inner wall of the fixed seat 4, and also includes an optical bar 11 installed in the inner cavity of the second slide groove 10, and second sliders 12 are symmetrically slidably sleeved on the left and right sides of the outer wall of the optical bar 11. Another connecting block 13 is installed on the rear side of the outer wall of each second slider 12, and the other connecting block 13 is rotatably connected to the front side wall of the roller 14 through a bearing. When the first slider 7 moves along the inner cavity of the first slide groove 5 under the action of the rotating screw 6, it can drive the two connecting blocks 13 and the roller 14 to move synchronously, and then drive the second slider 12 on the front side to move synchronously along the outer wall of the optical bar 11.

[0028] In order to ensure that the lifting ring 17 hooked at the bottom end of the second lifting part 3 can drive the fixed base 4 to move up and down stably, the lifting ring 17 is installed in the middle position of the upper surface of the fixed base 4, so as to avoid the situation where the hooking position of the lifting ring 17 is skewed and causes the fixed base 4 to tilt during the lifting process.

[0029] See Figure 1 As shown, the bottom end of the first lifting part 2 is hooked on the right free end of the steel cage 18. When the steel cage 18 is lifted, the first lifting part 2 is used for vertical lifting, and the second lifting part 3 is used for turning over lifting. The two work together to realize the vertical lifting of the steel cage 18 into the hole.

[0030] The working principle of a steel cage lifting device in this embodiment is as follows:

[0031] By means of the turned-on motor 9 driving the screw 6 to rotate, the screw 6 drives the two first sliding blocks 7 symmetrically screwed on the left and right sides of the outer wall to move synchronously toward the middle or to both sides. The two first sliding blocks 7 moving toward the middle drive the connecting block 13 and the roller 14 connected to the outer wall to move synchronously toward the middle, so that the distance between the two rollers 14 becomes smaller, and the length of the two free ends of the lifting rope 15 on the outer walls of the two rollers 14 extending downward becomes longer, and the buckles 16 at the two free ends of the lifting rope 15 are hooked at 1 / 3 and 2 / 3 of the steel cage 18 respectively, so that the equipment meets the lifting requirements of the longer steel cage 18 and avoids the situation where the lifting point is too centered relative to the steel cage 18; conversely, by means of the direction of rotation of the output end of the motor 9, the two rollers 14 can be moved synchronously to both sides, which can shorten the extension distance of the two free ends of the lifting rope 15, so that the equipment meets the lifting requirements of the shorter steel cage 18;

[0032] When the first slider 7 moves along the inner cavity of the first slide groove 5 under the action of the rotating screw 6, it can drive the two connecting blocks 13 and the roller 14 to move synchronously, and then drive the second slider 12 on the front side to move synchronously along the outer wall of the optical bar 11. Under the joint action of the second slider 12 and the first slider 7, the two rollers 14 are always adjusted in the horizontal direction;

[0033] The utility model can flexibly adjust the extended length of the lifting rope according to the different lengths of the steel cage, so that the lifting equipment can meet the lifting and use requirements of different steel cages. Compared with the existing fixed-length lifting rope, the utility model can better ensure the stability of the steel cage during lifting, and at the same time ensure that the two rollers 14 are still symmetrical with respect to the central axis of the lifting ring 17 after the adjustment position, thereby ensuring that the lifting rope 15 slidingly arranged on the outer wall of the two rollers 14 is symmetrical and extends to the same length after the adjustment position, avoiding the situation where the lifting steel cage is skewed due to the different lengths of the left and right side walls of the lifting rope 15.
