[0022] The mounting frame 1 is installed at a high place, and the electric drum 1 2 and the electric drum 21 are used to reel in and release the steel cable 3. The steel cable 3 installed on the electric drum 1 2 will rise with the placement plate 6 during the reeling process. The steel cable 3 installed on the electric drum 1 2 is fixed on the pulley block 1 4 after passing through the pulley block 1 4 and the pulley block 2 41. The cable winding method of the steel cable 3 installed on the electric drum 1 2 reduces the force on the steel cable 3 during the rising process with the placement plate 6, which is convenient for the device to lift heavier objects. The placement plate 6 is used to place objects to be The lifting steel structure, the threaded screw 62 is installed on the screw motor 61. After the screw motor 61 is started, the threaded screw 62 is lifted and lowered under the action of the screw motor 61. The moving threaded screw 62 will move with the pressure block 63.

The limit rod 64 plays a guiding and limiting role. The cooperation between the limit rod 64 and the groove of the placement plate 6 penetrated by the limit rod 64 ensures the stability of the pressure block 63 during the lifting process. The pressing block 63 is used to fix the lifted steel structure, ensuring the stability of the steel structure during the lifting process. During the use of the device, the fixing cylinder 5 is fixed to the ground, and the placing plate 6 will move along the steel cable 3 connected to the fixing cylinder 5 during the lifting process. The steel cable 3 connected to the fixing cylinder 5 plays a guiding and limiting role, avoiding the placing plate 6 from shaking greatly during the lifting process, which affects the stability of the placing plate 6 during the lifting process. By setting two steel cables 3 connected to the fixing cylinder 5, the working effect of the steel cable 3 connected to the fixing cylinder 5 is guaranteed. During the use of the device, the fixing cylinder 5 is fixed on the ground. After the fixing cylinder 5 is fixed, the electric reel 21 is controlled to reel in the steel cable 3 installed on the fixing cylinder 5, so that the steel cable 3 connected to the fixing cylinder 5 is in a straight state, ensuring the working effect of the steel cable 3 installed on the fixing cylinder 5. The side wall protrusion of the fixing cylinder 5 and the matching groove can fix the fixing cylinder 5 on the placing plate 6, ensuring the stability of the fixing cylinder 5 after being installed on the placing plate 6.

[0023] When the user rotates the turntable 52, the turntable 52 will rotate with the connecting rod 54. When the connecting rod 54 rotates, the side wall protrusion of the connecting rod 54 and the groove that cooperates with the side wall protrusion of the connecting rod 54 will make the threaded nail 53 rotate together with the connecting rod 54. When the threaded nail 53 rotates, the threaded nail 53 moves along the fixing tube 5 under the action of the thread. The moving threaded nail 53 will drill into the inside of the ground, ensuring the stability of the fixing tube 5 after it is installed on the ground. The threaded nail 53 rotates and drills into the inside of the ground, reducing the physical strength consumed by the user when fixing the fixing tube 5 on the ground, making it easier for the user to fix the fixing tube 5 on the ground. A ring-shaped protrusion with a T-shaped cross-section is provided on the top, and a groove cooperating with the ring-shaped protrusion is provided on the bottom surface of the turntable 52, thereby ensuring the stability of the turntable 52 during rotation. The cooperation between the side wall of the inner groove of the threaded nail 53 and the side wall protrusion of the connecting rod 54 plays a limiting role, thereby preventing the threaded nail 53 from detaching from the connecting rod 54 during movement, thereby ensuring the stability of the threaded nail 53 during movement. The length of the fixing tube 5 is the same as the length of the threaded nail 53, thereby ensuring that the tip of the threaded nail 53 is inside the fixing tube 5 when the fixing tube 5 is not in use, thereby preventing the fixing tube 5 from injuring the user when not in use, thereby affecting the safety of the device.

[0024] Specifically, two fixing blocks 55 are installed on the side wall of the groove where the placement plate 6 cooperates with the fixing tube 5 via springs 56 , and a groove that cooperates with the fixing blocks 55 is provided on the side wall of the fixing tube 5 .

[0025] The fixing cylinder 55 can be fixed on the placement plate 6 by the cooperation of the fixing block 55 and the side wall groove of the fixing cylinder 5, ensuring the stability of the fixing cylinder 5 after it is placed on the side wall groove of the placement plate 6. When the user puts the fixing cylinder 5 into the inside of the side wall groove of the placement plate 6, the fixing block 55 will be pushed. After the fixing cylinder 5 is completely entered into the inside of the side wall groove of the placement plate 6, the fixing block 55 quickly returns to its original position under the action of the spring 56, ensuring the working effect of the fixing block 55. A protrusion is provided on the side wall of the fixing block 55, and a groove is provided on the side wall of the groove for installing the fixing block 55, and the cooperation of the groove for matching with the side wall protrusion of the fixing block 55 and the side wall protrusion of the fixing block 55 can prevent the fixing block 55 from being separated from the groove for installing the fixing block 55 during movement, thereby ensuring the stability of the fixing block 55 during movement. The shape of the tip of the fixing block 55 is an inclined surface inclined to both sides, ensuring that the user will not be hindered in installing the fixing cylinder 5 on the placement plate 6 and removing the fixing cylinder 5 from the placement plate 6.

[0027] The roller 51 and the guide wheel 7 play a guiding role. When the steel cable 3 installed on the fixed cylinder 5 is impacted, the steel cable 3 installed on the fixed cylinder 5 will contact the roller 51, and the roller 51 plays a role of blocking the steel cable 3, thereby ensuring the stability of the connection between the fixed cylinder 5 and the steel cable 3. The roller 51 is rotatably installed on the turntable 52, so that the user can adjust the position of the roller 51, thereby ensuring the working effect of the roller 51. The guide wheel 7 can reduce the wear of the steel cable 3 installed with the fixed cylinder 5 during the lifting and lowering of the placement plate 6, thereby extending the service life of the steel cable 3 installed with the fixed cylinder 5. By arranging guide wheels 7 at both ends of the groove through which the steel cable 3 installed with the fixed cylinder 5 passes, the working effect of the guide wheel 7 is ensured.

[0028] Specifically, a plurality of pulleys are provided on the pulley block 1 4 and the pulley block 2 41 , and the number of the steel cables 3 installed on the electric drum 1 2 is the same as the number of the pulleys of the pulley block 1 4 and the pulley block 2 41 .

[0029] By arranging several pulleys on pulley block 1 4 and pulley block 2 41, the number of steel cables 3 for controlling the lifting and lowering of the placement plate 6 during operation of the device is increased, thereby ensuring the stability of the placement plate 6 during the lifting and lowering process. The number of steel cables 3 passing around pulley block 1 4 and pulley block 2 41 is the same as the number of pulleys of pulley block 1 4 and pulley block 2 41, thereby ensuring that each pulley on pulley block 1 4 and pulley block 2 41 is passed around by a steel cable 3. The arrangement of the steel cables 3 ensures that when one steel cable 3 is damaged, the remaining steel cables 3 will not be affected, thereby improving the safety of the device.

[0030] Specifically, the top and bottom of the frame of pulley block 1 4 and pulley block 2 41 are respectively provided with a mounting plate 42 and a mounting groove 43, and the mounting plate 42 and the mounting groove 43 are provided with a plurality of matching through holes, and pulley block 1 4 and pulley block 2 41 can be installed together by the cooperation of bolts and nuts with threaded holes.

[0031] When the steel structure that the device needs to lift is too heavy, the new pulley block 1 4 and the new pulley block 2 41 are respectively installed on the old pulley block 1 4 and the old pulley block 2 41 through the cooperation of the mounting plate 42 and the mounting groove 43, and then the new pulley block 1 4 and the pulley block 2 41 are respectively fixed to the old pulley block 1 4 and the pulley block 2 41 through the cooperation of bolts and nuts with the through holes of the mounting plate 42 and the mounting groove 43, thereby increasing the number of pulleys that the steel cable 3 installed on the electric drum 1 2 can pass around, and further reducing the force applied to the steel cable 3 installed on the electric drum 1 2 during the process of the device lifting the steel structure. An array of cooperating through holes is provided on the mounting plate 42 and the mounting groove 43, thereby ensuring the stability of the cooperation between the two pulley blocks 1 4 and the two pulley blocks 2 41.

[0032] Specifically, an arc-shaped portion is provided at the center of the pressing block 63 , horizontal portions are provided at both ends of the arc-shaped portion of the pressing block 63 , and a cushion is provided on the bottom surface of the pressing block 63 .

[0033] The arc-shaped portion in the center of the pressing block 63 is used to fix the tubular component. The arc-shaped portion of the pressing block 63 increases the contact area between the pressing block 63 and the tubular component, thereby improving the stability of the tubular component during the fixing process. The horizontal portion of the pressing block 63 is used to fix the plate-like component. The horizontal portion of the pressing block 63 ensures the fixing effect of the pressing block 63 on the plate-like component. The soft pad arranged on the pressing block 63 increases the friction between the threaded nail 53 and the component placed on the placement plate 6, thereby ensuring the stability of the component during the lifting process.

[0034] The working principle and use process of the utility model are as follows: the mounting frame 1 is installed at a high place, and the electric reel 1 2 and the electric reel 21 are controlled to release the steel cable 3. The released steel cable 3 will fall to the ground with the fixed cylinder 5 and the placement plate 6, and the fixed cylinder 5 will be placed on the ground, and the turntable 52 will rotate with the connecting rod 54 during the rotation process. When the connecting rod 54 rotates, the threaded nail 53 is rotated by the connecting rod 54 under the action of the bottom protrusion of the connecting rod 54 and the groove matched therewith. The rotating screw nail 53 extends out of the fixed tube 5 under the action of the thread, and the moving screw nail 53 drills into the ground, and the fixed tube 5 is fixed on the ground. The screw motor 61 is started, and the screw rod 62 rises with the pressure block 63 under the action of the screw motor 61, and the part to be lifted is placed on the placement plate 6. The screw motor 61 is started in the reverse direction, and the pressure block 63 descends, and the part is fixed by the pressure block 63, and the electric reel 2 is controlled to reel in the steel cable 3, and the reeled steel cable 3 will rise with the placement plate 6.
