A lifting equipment for construction

Abstract

The present invention belongs to the technical field of building construction, and specifically is a hoisting equipment for building construction, comprising a base and a hook, wherein a support column is rotatably installed on the top of the base, which is used in conjunction with other components of the equipment through the setting of a limit mechanism. If a breakage or detachment occurs during the hoisting process, the pressure on the positioning plate disappears at this time, and then under the action of the elastic force of the ejection spring, the sliding block drives the positioning plate to reset through the connecting column, and then the positioning plate drives the positioning column to move up and reset. At this time, the pressure on the conical block disappears, and then under the action of the elastic force of the limit spring, the conical block pops out of the limit slot and is reinserted into the slot, thereby solving the problem that when the existing small crane is in use, the main shaft can rotate, and when the heavy object is rotated for hoisting, the connection between the crane and the heavy object is easily disconnected, and the disconnected crane and its connecting parts will be affected by inertia and continue to rotate, which may easily cause injury to the staff.

[0004] When the existing small crane is in use, the main shaft can rotate, but when the heavy object is hoisted, the connection between the crane and the heavy object is easily disconnected, and the disconnected crane and its connecting parts will continue to rotate due to inertia, which may easily cause injuries to workers. Therefore, a hoisting device for construction is proposed to address the above problems. Summary of the Invention

[0010] In a preferred embodiment, the bottom of the support plate is provided with anti-slip protrusions, and the pulleys are provided in four groups.

[0011] In a preferred embodiment, a buffer pad is provided on the outer surface of the positioning plate, and a limit block is fixedly installed in the groove.

[0032] Example

[0033] Reference Figure 1-8 ,

[0034] A lifting device for construction, comprising a base 1 and a hook 20, a support column 2 is rotatably mounted on the top of the base 1, a driving groove 3 is provided in the base 1, a motor 4 is fixedly mounted in the driving groove 3, the output end of the motor 4 passes through the base 1 and is fixedly connected to the bottom end of the support column 2, a groove 6 is provided on the top of the support column 2, a sliding block 7 is slidably mounted in the groove 6, one end of the sliding block 7 is elastically connected to the inner bottom wall of the groove 6 by an ejection spring 9, a connecting column 10 is fixedly mounted on the other end of the sliding block 7, a positioning plate 11 is fixedly mounted on the top of the connecting column 10, a lifting plate 12 is fixedly mounted on the top of the positioning plate 11, an annular groove 13 is provided on the top of the base 1, a positioning column 14 is fixedly mounted on the bottom of the lifting plate 12, the bottom end of the positioning column 14 is inserted into the annular groove 13, and a card groove 15 is provided on the inner side wall of the annular groove 13;

[0035] A limiting mechanism 5 is provided on the positioning column 14, and the limiting mechanism 5 includes a limiting groove 51 provided in the annular groove 13, and a slidingly connected driving block 52 is installed in the limiting groove 51. One end of the driving block 52 is elastically connected to the inner side wall of the limiting groove 51 through a limiting spring 53, and the other end of the driving block 52 is provided with a fixedly connected conical block 54, and the other end of the conical block 54 extends out of the through groove 55 provided on the positioning column 14 and is inserted into the card slot 15. During operation, since the main shaft of the existing small crane can rotate when in use, it is easy to disconnect the connection between the crane and the heavy object when the heavy object is rotated during hoisting, and the disconnected crane and its connecting parts will be affected by inertia and continue to rotate, which may easily cause injury to the staff, so this equipment is adopted.

[0036] Specifically, after the equipment is moved to the construction site and the limit fixation is completed, the hoisting operation can be carried out. During the hoisting process, the gravity generated by the hoisting weight is applied to the connecting column 10 through the positioning plate 11, and the connecting column 10 moves down and retracts into the groove 6. During this process, the connecting column 10 applies pressure to the ejection spring 9 through the sliding block 7, and the bottom end of the positioning column 14 also moves down, so that the conical block 54 is subjected to pressure and retracts into the limit groove 51. The conical block 54 applies pressure to the limit spring 53 through the driving block 52, and the positioning column 14 rotates along with the support column 2. If it breaks and detaches during the hoisting process,

[0037] At this time, the pressure on the positioning plate 11 disappears, and then under the action of the elastic force of the ejection spring 9, the sliding block 7 drives the positioning plate 11 to reset through the connecting column 10, and then the positioning plate 11 drives the positioning column 14 to move up and reset. At this time, the pressure on the conical block 54 disappears, and then under the action of the elastic force of the limit spring 53, the conical block 54 pops out of the limit groove 51 and reinserts into the card slot 15, thereby solving the problem that the main shaft of the existing small crane can rotate when in use, and the connection between the crane and the heavy object is easily disconnected when the heavy object is rotated during hoisting. The disconnected crane and its connecting parts will be affected by inertia and continue to rotate, which may easily cause injury to the staff.

[0038] There are four groups of positioning columns 14, and the four groups of positioning columns 14 are distributed in a ring. There are several groups of card slots 15, and the several groups of card slots 15 are distributed in a ring at equal intervals. When working, the four groups of positioning columns 14 are used in conjunction with the several card slots 15 to ensure the positioning effect of the support column 2.

[0039] A moving assembly 8 is provided at the bottom of the base 1, and the moving assembly 8 includes a pulley 81 movably installed at the bottom of the base 1. Fixedly connected electric telescopic rods 82 are installed on both sides of the bottom of the base 1, and a fixedly connected support plate 83 is installed at the other end of the electric telescopic rod 82. A sliding groove 84 adapted to the pulley 81 is provided on the support plate 83.

[0040] During operation, the setting of the moving component 8 facilitates the movement of the equipment and the positioning of the equipment at any time. Specifically, the pulley 81 drives the movement of the entire equipment. When it moves to the construction site, the electric telescopic rod 82 is started, and the electric telescopic rod 82 drives the support plate 83 to move downward until the bottom of the support plate 83 contacts the ground, and then completes the limitation of the pulley 81, avoiding the equipment from moving on its own during the lifting process, thereby ensuring the stability of operation.

[0041] The bottom of the support plate 83 is provided with anti-slip protrusions, and four groups of pulleys 81 are provided. During operation, the anti-slip protrusions provided at the bottom of the support plate 83 strengthen the friction between the support plate 83 and the ground, thereby strengthening the limiting of the pulley 81.

[0042] A buffer pad is provided on the outer surface of the positioning plate 11, and a limit block is fixedly installed in the groove 6. During operation, the buffer pad is provided on the outer surface of the positioning plate 11 to reduce the damage caused by the positioning plate 11 falling and contacting the top of the support column 2. The limit block is fixedly installed in the groove 6 to facilitate limiting the sliding block 7 and avoid damage to the equipment.

[0043] A transmission plate 16 is fixedly installed on one side of the support column 2, and the other end of the transmission plate 16 is fixedly connected to the bottom of the lifting plate 12. The transmission plate 16 is tilted. When working, the setting of the transmission plate 16 ensures the stability of the equipment operation and avoids breakage and damage during use.

[0044] A maintenance box 17 is fixedly installed on the top of the base 1. When working, the maintenance box 17 is fixedly installed on the top of the base 1 to facilitate maintenance of the equipment at any time. At the same time, a weight block is set in the maintenance box 17 to further ensure the stability of the equipment operation.

[0045] Side plates 22 are welded to the left and right sides of the hook 20, and fixed blocks 18 are welded to the lower surfaces of the two sets of side plates 22. A rotating rod 24 is hinged to one side of the fixed block 18 through a bearing 23. A hole is provided inside the fixed block 18. A motor 21 is provided on the side of the fixed block 18 away from the rotating rod 24. The output shaft of the motor 21 passes through the fixed block 18 and is connected to the inside of the rotating rod 24. The outer surface of the rotating rod 24 is disassembled and connected with a cable 25.

[0046] By pulling the two sets of cables 25, the direction in which the cargo connected to the lower end of the hook 20 rotates in the air is controlled, thereby minimizing the possibility that the cargo at the lower end of the hook 20 collides with the building in the air and causes damage to the cargo, and minimizing the possibility that the cargo at the lower end of the hook 20 falls due to the rotation of the hook 20 in the air. In addition, by starting the second motor 21 to drive the cable 25 on the outer surface of the rotating rod 24, the staff can quickly recycle the wound cable 25, thereby reducing the workload of the staff to a certain extent.

[0047] A protective cover 19 is provided on the outer surface of the cable 25 , and the protective cover 19 protects the cable 25 , thereby improving the service life of the cable 25 to a certain extent.

[0048] The end of the cable 25 away from the rotating rod 24 is detachably connected to a strap 26 , which is tied to the hand of the worker so that the cable 25 cannot fall off the hand when the worker pulls the cable 25 .

[0049] The position of the motor 21 is located at the lower end of the side plate 22, so that the side plate 22 protects the motor 21, thereby improving the service life of the motor 21 to a certain extent, and thus reducing the maintenance cost of the device in the later stage to a certain extent.

[0050] The implementation principle of the embodiment of the subject of the hoisting equipment for construction is as follows:

[0051] After moving this equipment to the construction site and completing the limit fixation, the hoisting operation can be carried out. During the hoisting process, the gravity generated by the hoisting weight is applied to the connecting column 10 through the positioning plate 11, and the connecting column 10 moves down and retracts into the groove 6. During this process, the connecting column 10 applies pressure to the ejection spring 9 through the sliding block 7, and the bottom end of the positioning column 14 also moves down, so that the conical block 54 is subjected to pressure and retracts into the limit groove 51. The conical block 54 applies pressure to the limit spring 53 through the driving block 52, and the positioning column 14 rotates along with the support column 2.

[0052] If the breaker 11 is broken and detached during the lifting process, the pressure on the positioning plate 11 disappears, and then under the elastic force of the ejection spring 9, the sliding block 7 drives the positioning plate 11 to reset through the connecting column 10, and then the positioning plate 11 drives the positioning column 14 to move up and reset. At this time, the pressure on the conical block 54 disappears, and then under the elastic force of the limit spring 53, the conical block 54 pops out of the limit groove 51 and reinserts into the card slot 15, thereby solving the problem that the main shaft of the existing small crane can rotate when in use, and the crane and the heavy object are easily rotated when the crane is hoisted. The connection between the objects is disconnected, and the disconnected crane and its connecting parts will continue to rotate due to inertia, which may easily cause injury to the workers. The setting of the moving component 8 facilitates the movement of the equipment and can also position the equipment at any time. Specifically, the pulley 81 drives the entire equipment to move. After moving to the construction site, the electric telescopic rod 82 is started, and the electric telescopic rod 82 drives the support plate 83 to move downward until the bottom of the support plate 83 contacts the ground, and then completes the limit of the pulley 81, avoiding the equipment from moving on its own during the lifting process, thereby ensuring the stability of operation.

[0053] By pulling the two sets of cables 25, the direction in which the cargo connected to the lower end of the hook 20 rotates in the air is controlled, thereby minimizing the possibility that the cargo at the lower end of the hook 20 collides with the building in the air and causes damage to the cargo, and minimizing the possibility that the cargo at the lower end of the hook 20 falls due to the rotation of the hook 20 in the air. In addition, by starting the second motor 21 to drive the cable 25 on the outer surface of the rotating rod 24, the staff can quickly recycle the wound cable 25, thereby reducing the workload of the staff to a certain extent.
