[0002] Crane is the popular name for cranes, which are widely used in a series of heavy industrial products such as ships, equipment, machinery, molds, etc. Cranes are generally composed of two parts: a power unit and a bracket.
[0003] Installation cranes are widely used in the electromechanical installation industry. However, since the weight of the lifting rope is heavy, the sudden force on the hook during lifting may cause damage to the hook and the connecting structure. In addition, most cranes on the market are large in size, which makes them inconvenient to move and fix in indoor environments. Utility Model Content
[0004] Based on the above-mentioned problems existing in the prior art, the purpose of the embodiment of the present application is to provide a kind of installation crane, including a telescopic column, a base is connected below the telescopic column, a beam is connected above the telescopic column, a mobile crane is installed on the beam, a lifting rope is connected to the mobile crane, one end of the lifting rope is connected to a connecting plate, limiting plates are connected on both sides of the connecting plate, the limiting plates are L-shaped and slide in the limiting grooves, the connecting plate is slidably connected to the mobile plate, a spring is connected inside the mobile plate, one end of the spring is connected to the bottom of the connecting plate, limiting grooves are arranged on both sides of the mobile plate, and a fixed block is connected below the mobile plate.
[0005] Furthermore, the fixed block is connected to a fixed rod, and a rotating plate is rotatably connected to the fixed block. Torsion springs are connected to both sides of the rotating plate, and one end of the torsion spring is connected to the fixed block. The torsion spring enables the rotating plate to be re-clamped on the connecting rod after rotation, and the initial state of the torsion spring enables the rotating plate to always maintain a vertical state, thereby locking the hook to prevent the connecting rope on the heavy equipment from falling from the hook.
[0006] Furthermore, a hook is connected below the movable plate, a convex strip is provided on the hook, a groove is provided at one end of the hook, a connecting rod is connected in the groove, the rotating plate is buckled on the connecting rod, a universal wheel is installed below the base, a mounting plate is connected to the base, a motor is installed on the mounting plate, and the motor output shaft is connected to a threaded rod.
[0007] Furthermore, a moving block is installed on the threaded rod, a threaded sleeve is installed on the moving block, the threaded sleeve is threadedly connected to the threaded rod, threads are provided at both ends of the threaded rod and the threads at both ends are in opposite directions, an anti-slip pad is connected under the support plate, a hinged plate is rotatably connected to the moving block, and one end of the hinged plate is rotatably connected to the support plate.
[0008] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: by setting the connecting plate, the moving plate, the spring, the limiting plate and the limiting groove, the moving plate is forced to move downward during lifting, thereby lengthening the spring, and the spring is used to buffer the gravity borne by the hook, thereby avoiding damage to the lifting rope or the hook caused by the sudden gravity, and when the moving plate moves, the limiting plate will slide in the limiting groove at the same time, and when the limiting plate moves to the end of the limiting groove, the moving plate will be stopped from moving further, thereby preventing the spring from being excessively elongated and causing the spring elastic force to decrease, thereby ensuring the service life of the spring bearing;
[0009] By setting a telescopic column, a universal wheel, a threaded rod, a moving block, a hinged plate and a support plate, the telescopic column and the universal wheel can be retracted, so that the height of the installation crane can be lowered during movement to facilitate the movement of the workers. When moving to the working position, the motor is started to rotate the threaded rod, so that the two moving blocks can move in opposite directions, so that the support plate is pushed to move through the hinged plate, so that the support plate contacts the ground, thereby supporting and fixing the installation crane to prevent the installation crane from moving suddenly during lifting;
[0010] By setting a fixed block, a fixed rod, a rotating plate, a torsion spring and a connecting rod, the rotating plate will be pushed when the rope is connected to the hook, so that the rotating plate rotates on the fixed rod and twists the torsion spring. After the connection is completed, the torsion spring rotates, so that the rotating plate is re-locked on the connecting rod, thereby preventing the connecting rope from falling off the hook and improving the safety of use.

DETAILED DESCRIPTION
[0017] Now, the present application will be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present application in a schematic manner, and therefore only shows the components related to the present application.
[0018] like Figures 1 to 4 As shown, the present application provides an installation crane, including a telescopic column 1, a base 2 is connected to the bottom of the telescopic column 1, a beam 3 is connected to the top of the telescopic column 1, a mobile crane 4 is installed on the beam 3, a lifting rope 5 is connected to the mobile crane 4, one end of the lifting rope 5 is connected to a connecting plate 6, both sides of the connecting plate 6 are connected to limiting plates 20, the limiting plates 20 are L-shaped and slide in limiting grooves 19, the connecting plate 6 is slidably connected to a mobile plate 7, a spring 18 is connected inside the mobile plate 7, one end of the spring 18 is connected to the bottom of the connecting plate 6, limiting grooves 19 are provided on both sides of the mobile plate 7, and a fixed block 22 is connected below the mobile plate 7.
[0019] In actual operation, the limit plate 20 moves in the limit groove 19, and the L-shaped limit plate 20 can better hook the movable plate 7, thereby limiting the moving distance of the movable plate 7 and preventing the movable plate 7 from excessively stretching the spring 18 and causing damage to the spring 18.
[0020] A fixing rod 23 is connected to the fixing block 22, and a rotating plate 24 is rotatably connected to the fixing block 22. Torsion springs 25 are connected to both sides of the rotating plate 24. One end of the torsion spring 25 is connected to the fixing block 22. The torsion spring 25 enables the rotating plate 24 to be re-clamped on the connecting rod 27 after rotation, and the initial state of the torsion spring 25 enables the rotating plate 24 to always maintain a vertical state, thereby locking the hook 8 to prevent the connecting rope on the heavy equipment from falling off the hook 8.
[0021] A hook 8 is connected below the movable plate 7, a convex strip 21 is provided on the hook 8, a groove 26 is provided at one end of the hook 8, a connecting rod 27 is connected in the groove 26, a rotating plate 24 is buckled on the connecting rod 27, a universal wheel 9 is installed below the base 2, a mounting plate 10 is connected to the base 2, a motor 11 is installed on the mounting plate 10, and a threaded rod 12 is connected to the output shaft of the motor 11.
[0022] In actual operation, the convex strip 21 on the hook 8 increases the friction between the hook 8 and the rope to prevent the rope from sliding on the hook 8 and causing the equipment to shake during lifting, and the multiple universal wheels 9 installed on a base 2 make the movement of the installed crane more stable.
[0023] A moving block 13 is installed on the threaded rod 12, and a threaded sleeve 14 is installed on the moving block 13. The threaded sleeve 14 is threadedly connected to the threaded rod 12. Both ends of the threaded rod 12 are provided with threads and the directions of the threads at both ends are opposite. An anti-slip pad 17 is connected under the support plate 16. A hinged plate 15 is rotatably connected to the moving block 13, and one end of the hinged plate 15 is rotatably connected to the support plate 16.
[0024] In actual operation, the two moving blocks 13 can move in opposite directions through the threads in opposite directions at both ends of the threaded rod 12, so that the support plate 16 is pushed by the hinge plate 15 to fix the installation crane, and the anti-slip pad 17 can prevent the support plate 16 from sliding. When the support plate 16 supports and fixes the installation crane, the universal wheel 9 can continue to contact the ground, thereby making the fixation of the installation crane more stable.
[0025] Here’s how it works:
[0026] After the staff moves the installation crane to the working position through the universal wheel 9, the threaded rod 12 is rotated by starting the motor 11, so that the two moving blocks 13 installed on the threaded rod 12 can move in opposite directions, thereby pushing the support plate 16 to move through the hinged plate 15, so that the support plate 16 can fix the installation crane, and when the hook 8 is installed with the connecting rope, the rotating plate 24 will rotate on the fixing rod 23 and twist the torsion spring 25, and after the rope connection is completed, the torsion spring 25 will rotate, so that the rotating plate 24 will be re-clamped on the connecting rod 27, thereby preventing the connecting rope from falling off the hook 8, and the heavy equipment is lifted by the mobile crane 4. When the heavy equipment is lifted, the mobile plate 7 is forced to move downward and stretch the spring 18, so that the gravity suddenly borne by the hook 8 is buffered by the spring 18, and when the mobile plate 7 moves, the limit plate 20 will slide in the limit groove 19, thereby limiting the moving distance of the mobile plate 7 by the limit groove 19.
