A fourth pull rope is fixedly connected to both sides of the upper surface of the horizontal column, and the end of each fourth pull rope away from the horizontal column is installed on the tower crane through a winch.

[0013] Furthermore, pulling components are equidistantly arranged between the two fourth pull ropes and the pull rope mechanism located above the horizontal column, and each pulling component includes a second rope ring fixedly buckled on the pull rope mechanism, and the two sides of the second rope ring are respectively fixedly connected with pull ropes, and the ends of the pull ropes are fixedly connected with first rope rings, and the first rope rings on both sides are respectively fixedly buckled on the fourth pull ropes on both sides.

[0014] Furthermore, vertical guardrails are provided on both sides of the horizontal column, and buckle cables are fixedly connected to both ends of the horizontal column. The ends of the buckle cables are fixedly connected to buckles, and the buckles on both sides are correspondingly slidably inserted into the guardrails and can slide vertically along the guardrails with the horizontal column.

[0015] Furthermore, a method for using a lifting device for prefabricated housing construction comprises the following steps: S1: After the end of the pull rope mechanism installed on the tower crane through the hoist passes through the through slots of the horizontal column and the slide rail plate, it is connected to the connecting steel bars of the assembled material. At this time, the first connecting arms hinged to the two ends of the horizontal column and the slide rail plate connected by the first connecting arms on both sides are in a horizontal state; S2: The two sets of buckle mechanisms slidably arranged on the slide rails control the bite arm assemblies thereon through the driving structure on the buckle mechanisms, and symmetrically clamp them on both sides of the assembled material. At this time, the first airbags arranged on the bite arm assemblies are pressed on the surface of the upper assembled material, and the second spring built into the first airbag is in a compressed state and still retains deformation space; S3: The winch works, and the pull rope mechanism drives the assembled material, the cross column, the first connecting arm, the slide rail plate and the snap mechanism to move upward as a whole. During this process, the assembled material gradually changes from a horizontal state to a vertical state. The first airbag and the built-in second spring are used to do work and consume energy when the assembled material rotates greatly around the pull rope mechanism.

[0016] The beneficial effects of the present invention are: The present invention uses a pull rope mechanism and a winch as a driving device to drive the lifting of prefabricated materials. The pull rope mechanism passes through the through grooves formed in the middle of the cross column and the slide rail plate and is connected to the connecting steel bar in the middle of the prefabricated material. During the movement, the cross column, the slide rail plate and the prefabricated material can be moved synchronously. At the same time, two sets of snap mechanisms slidably connected on the slide rail plate can be used to adjust the relative relationship between the snap mechanisms and the prefabricated material as needed according to the size of the prefabricated material. The snap mechanisms are used to assist in clamping and fixing the prefabricated material. The first airbag on the snap mechanism and the second spring inside the first airbag are used to consume energy when the prefabricated material rotates greatly around the pull rope mechanism. This can not only limit the movement range of the prefabricated material, but also assist the prefabricated material in quickly restoring a stable state.

[0017] When the prefabricated materials are connected and installed, the right-angled notch of the corner pad can be clamped on the corner of the other side of the prefabricated material, and the corner side of the prefabricated material can be fitted through the pad wheel. When one side of the prefabricated material is hung and lifted by the third pull rope, the other side of the prefabricated material will touch the ground. Due to the existence of the protection mechanism, the corner pad and the pad wheel replace the other side of the prefabricated material to touch the ground, thereby improving the protection capability of the prefabricated material.

[0018] The present invention starts the winches of the first and fourth pull ropes for winding, and uses the mechanical force of the tower crane to lift the prefabricated materials from a horizontal state to a vertical state for hoisting, thereby eliminating the trouble of manually erecting the prefabricated materials on the ground before connecting the device, saving manpower and material resources.

[0019] The present invention winds up the first and fourth pull ropes through the winch so that the side of the assembled material connected to the third pull rope is lifted first, and then dragged along the ground to make the assembled material completely vertical. In this way, the bearing capacity of the pull rope mechanism and the fourth pull rope is gradually increased in the process of the assembled material changing from a horizontal to a vertical state. This can effectively reduce the tension suddenly generated when the pull rope mechanism directly lifts the assembled material, and effectively alleviate the force problem of the pull rope mechanism.

[0020] The present invention adjusts the bite arm assembly to adapt to the prefabricated material, so that the swing problem of the prefabricated material during the lifting process will also lose part of the power due to the increase in friction with the first airbag and the deformation of the second spring. In addition, through the existence of the second protective mechanism, the height of the constructed building is adapted to gradually splice the guard rail to the wall of the building, and through the sliding insertion of the buckle and the guard rail, the movement of the cross column tends to be stable, thereby effectively improving the transportation stability of the prefabricated material during the lifting process.

[0021] The first pull rope and the fourth pull rope of the present invention are used in combination with a winch and a tower crane in the prior art, which not only improves the adaptability of the device, but also solves the displacement problem of the device itself through the standard displacement of the tower crane, thereby improving the operability of the device.

[0022] The present invention synchronizes the first pull rope and the fourth pull rope through the presence of a pulling component, and through the relaxed state in the initial state of the pull rope, the operations of the first pull rope and the fourth pull rope do not affect each other. When problems occur in one of the first pull rope or the fourth pull rope or both of them, the second rope ring and the first rope ring at both ends of the pull rope will be seriously out of sync, and then the first pull rope and the fourth pull rope are pulled by the presence of the pulling component, thereby avoiding the risk of serious inconsistent operations and improving the safety of the device.

[0023] The present invention supports two third pull ropes extending from the second pull rope through an elastic component, so that when the tension of the third pull rope suddenly increases, it can be alleviated by the first spring, thereby protecting the third pull rope and preventing the third pull rope from breaking. The support of the third pull rope by the support column allows the connection between the third pull rope and the assembled material to form a triangular stable structure, further improving the connection safety of the device.

The pull rope mechanism 1 passes through the through groove 202 opened in the middle of the horizontal column 501 and the slide plate 201, and is connected to the connecting steel bar in the middle of the prefabricated material. During the movement, the horizontal column 501, the slide plate 201 and the prefabricated material can be moved synchronously. At the same time, by using two sets of snap mechanisms 3 slidably connected on the slide plate 201, the relative relationship between the snap mechanisms 3 and the prefabricated material can be adjusted as needed according to the size of the prefabricated material.

The inflation of the second airbag 309 further strengthens the control over the rotational movement of the prefabricated material, and can perform adaptive adjustments during the transportation of the prefabricated material, thereby improving the adaptive performance and stability of use.

[0041] A method for using a lifting device for construction of an assembled house according to the present invention comprises the following steps: S1: After the end of the pull rope mechanism 1 installed on the tower crane by the hoist passes through the through slot 202 of the horizontal column 501 and the slide rail plate 201, it is connected to the connecting steel bar of the assembled material.

During this process, the assembled material gradually changes from a horizontal state to a vertical state. The first airbag 305 and the built-in second spring 307 are used to do work and consume energy when the assembled material rotates greatly around the pull rope mechanism 1 as the axis.

[0042] A specific implementation of the present invention comprises the following steps: The winch carried by the fourth pull rope 504 is used to lower the horizontal column 501 along the guard rail 510, and the winch carried by the first pull rope 101 is used to lower the third pull rope 103 synchronously, and the first protection mechanism 2 is placed horizontally after it touches the ground; the end of the third pull rope 103 is correspondingly hung on the connecting steel bar of the prefabricated material, and the buckle mechanism 3 is adjusted to the side of the prefabricated material along the slide rail plate 201, and the motor of the screw rod 302 is started so that the two bite arm assemblies clamp the prefabricated material; the right-angle notch of the corner pad 403 is aligned and buckled on the other side corner of the prefabricated material, and the tension of the rope 402 is adjusted by the built-in winch of the casing 401; the first pull rope 101 and The winch of the fourth pull rope 504 works and moves upward along the guard rail 510 to lift the prefabricated material. During this process, the bearing capacity of the pull rope mechanism 1 and the fourth pull rope 504 is gradually increased in the process of the prefabricated material changing from a horizontal to a vertical state. This can effectively reduce the sudden tension generated when the pull rope mechanism 1 directly lifts the prefabricated material, and effectively alleviate the force problem of the pull rope mechanism 1. At the same time, the first pull rope 101 and the fourth pull rope 504 are used in combination with the winch and the tower crane in the prior art, which not only improves the adaptability of the device, but also solves the displacement problem of the device itself through the standard displacement of the tower crane, thereby improving the operability of the device.

[0043] The working principle of the present invention is as follows: After the third pull rope 103 and the connection steel bar of the prefabricated material are connected, the motor of the screw rod 302 is started to drive the sleeve block 303 to slide along the adjustment frame 301, thereby changing the distance between the two bite arm assemblies, so that the two bite arm assemblies fit the prefabricated material from both sides, and then through the winch upward moving device of the first pull rope 101 and the fourth pull rope 504, the prefabricated material placed horizontally on the ground is finally lifted vertically. When the prefabricated material is lifted, the wind blows and causes the prefabricated material to rotate with the first pull rope 101 as the axis. At this time, the bite arm assembly The existence of can control this movement, and when the rotation frequency of the assembled material with the first pull rope 101 as the axis increases, the assembled material continuously contacts and moves away from the first airbags 305 on the bite arm assemblies on both sides, so that the first airbags 305 form an inflated structure, and the second airbags 309 are further inflated through the first air chamber 308, the air guide tube 311 and the second air chamber 310. The second airbag 309 is inflated and expanded to strengthen the movement control of the assembled material, and adaptive adjustments are performed during the transportation of the assembled material to improve the adaptive performance of use.

[0044] When the prefabricated materials are connected and installed, the right-angled notch of the corner pad 403 will be clamped on the corner of the other side of the prefabricated material, and the corner side of the prefabricated material will be fitted through the pad wheel 404. When one side of the prefabricated material is hung and lifted by the third pull rope 103, the other side of the prefabricated material will touch the ground. Due to the presence of the protection mechanism 4, the corner pad 403 and the pad wheel 404 replace the other side of the prefabricated material to touch the ground, thereby improving the protection ability of the prefabricated material.

[0045] By starting the winches of the first pull rope 101 and the fourth pull rope 504 to reel them in, the mechanical force of the tower crane is used to lift the prefabricated materials from a horizontal state to a vertical state, thereby eliminating the trouble of manually erecting the prefabricated materials on the ground before connecting the device, saving manpower and material resources.

[0046] By winding up the first pull rope 101 and the fourth pull rope 504 with a winch, the side of the prefabricated material connected to the third pull rope 103 is lifted first, and then dragged along the ground to make the prefabricated material completely vertical. In this way, the bearing capacity of the pull rope mechanism 1 and the fourth pull rope 504 is gradually increased in the process of the prefabricated material changing from a horizontal to a vertical state. This can effectively reduce the sudden tension generated when the pull rope mechanism 1 directly lifts the prefabricated material, and effectively alleviate the force problem of the pull rope mechanism 1.

[0047] By adjusting the bite arm assembly to adapt to the prefabricated material, the swing problem of the prefabricated material during the lifting process will also be solved due to the increase in friction with the first airbag 305 and the deformation of the second spring 307, which will consume part of the power. In addition, through the existence of the second protective mechanism 5, the height of the constructed building is adapted, so that the guardrail 510 is gradually spliced ​​to the wall of the building, and through the sliding insertion of the buckle 509 and the guardrail 510, the movement of the cross column 501 tends to be stable, thereby effectively improving the transportation stability of the prefabricated material during the lifting process.

[0048] The first pull rope 101 and the fourth pull rope 504 are both used in combination with a winch and a tower crane in the prior art, which not only improves the adaptability of the device, but also solves the displacement problem of the device itself through the standard displacement of the tower crane, thereby improving the operability of the device.

[0049] Through the presence of the pulling component, the first pull rope 101 and the fourth pull rope 504 are synchronized, and through the relaxed state of the pull rope 506 in the initial state, the operations of the first pull rope 101 and the fourth pull rope 504 do not affect each other. When one of the first pull rope 101 or the fourth pull rope 504 or both have problems, the second rope ring 507 and the first rope ring 505 at both ends of the pull rope 506 will be seriously out of sync, and then the first pull rope 101 and the fourth pull rope 504 are pulled by the presence of the pulling component, thereby avoiding the risk of serious inconsistent operations and improving the safety of the device.

[0050] The two third pull ropes 103 extending from the second pull rope 102 are supported by an elastic component, so that when the tension of the third pull rope 103 suddenly increases, it can be alleviated by the first spring 210, thereby protecting the third pull rope 103 to prevent the third pull rope 103 from breaking, and the support of the third pull rope 103 by the support column 207 makes the connection between the third pull rope 103 and the assembled material form a triangular stable structure, further improving the connection safety of the device.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, it can be understood that various changes, modifications, substitutions, embellishments and variations can be made to these embodiments without departing from the principle and spirit of the present invention, which should be regarded as the protection scope of the present invention.
