[0001] The invention relates to the technical field of cranes, and in particular to a wall panel hoisting device. Background Art

[0002] In the prior art, when installing movable wall panels, a crane is usually used in conjunction with a lifting device to lift the wall panels. The existing lifting device is usually fixed by hanging, and the connection points between the two lifting ropes and the hanger are fixed, that is, the distance between the two lifting points is fixed. In this way, when lifting the wall panels, the lifting ropes are prone to not being completely in a vertical state, and the lifting points are prone to wear. In addition, it is difficult for the existing lifting device to finely adjust the position of the wall panel, so it is difficult to accurately position the lower end of the wall panel when it is inserted and matched with the ground bolt.

When the rotation driving device drives the left threaded rod and the right threaded rod to rotate respectively, the lifting rings at the upper ends of the two wall panel lifting ropes move in the left and right directions respectively to adjust the spacing between the two wall panel lifting ropes.

[0006] Furthermore, the left threaded rod and the right threaded rod are respectively movably installed in the installation cavity along the left and right directions, and the opposite ends of the left threaded rod and the right threaded rod are respectively connected with hydraulic driving mechanisms, and the hydraulic driving mechanisms are respectively used to drive the left threaded rod and the right threaded rod to move synchronously in the same direction. When the hydraulic driving mechanism drives the left threaded rod and the right threaded rod to move, the rotation driving device respectively drives the left threaded rod and the right threaded rod to rotate so as to adjust the relative positions of the two wall panel lifting ropes on the left threaded rod and the right threaded rod.

[0007] Furthermore, the hydraulic drive mechanism includes a hydraulic cylinder body fixed in the middle of the hanging beam, and the left and right ends of the hydraulic cylinder body respectively have a left chamber and a right chamber, the right end of the left threaded rod is sealed and slidably installed in the left chamber, and the left end of the right threaded rod is sealed and slidably installed in the right chamber, and the upper side of the hanging beam is respectively fixed with a left oil cylinder and a right oil cylinder, the left oil cylinder is connected with the left chamber through a left oil pipe, and the right oil cylinder is connected with the right chamber through a right oil pipe, and when one of the left oil cylinder and the right oil cylinder is supplied with oil into the hydraulic cylinder body, the other one draws oil from the hydraulic cylinder body to drive the left threaded rod and the right threaded rod to move synchronously to the left or right.

[0008] Furthermore, a limiting sleeve is respectively sleeved on the left threaded rod and the right threaded rod, and a limiting groove for accommodating a corresponding lifting ring is respectively opened on the inner wall of each limiting sleeve, and the lower part of each limiting groove passes through the inner wall of the limiting sleeve, so that the lower end of the lifting ring extends out of the limiting sleeve and is connected to the wall panel lifting rope.

[0009] Furthermore, a telescopic stop rod is provided on the outer wall of each limit sliding sleeve, and a limit tooth for cooperating with the telescopic stop rod is provided on the inner wall of the installation cavity. There are multiple limit teeth.

[0011] Furthermore, the hanger is a rectangular frame, which includes two front and rear cross beams and two left and right longitudinal beams. The two cross beams and the two longitudinal beams are connected end to end to form the rectangular frame, and the left and right ends of the hanger beam are respectively connected to the left and right longitudinal beams.

[0014] Furthermore, the hanging beam is a channel steel structure with an inverted U-shaped cross section, and the lower side of the hanging beam has a through groove extending in the left-right direction, and the through groove is used for two wall panel lifting ropes to move left and right.

[0015] The beneficial effects of the present invention are as follows: a wall panel hoisting device of the present invention, by setting two left and right threaded rods, allows the upper end of the wall panel hoisting rope to be sleeved in the thread groove of the threaded rod in the form of a lifting ring, so that when the threaded rod rotates, the lifting ring can be driven to move along the axial direction of the two threaded rods, thereby realizing stepless fine adjustment of the positions of the two wall panel hoisting ropes, so that it is easier to ensure that the spacing between the two wall panel hoisting ropes is adapted to the width of the wall panel, and ensure that the two wall panel hoisting ropes lift the wall panel in a vertical posture. At the same time, because the lifting ring can be adjusted steplessly on the threaded rod, when the lower end of the wall panel is inserted and matched with the ground bolt, it can be positioned more accurately. In general, the relative positions of the lifting points of the two wall panel hoisting ropes in the present invention are adjustable, which can realize precise adjustment of the wall panel lifting points, can adapt to different lifting spacings, and can also avoid wear of the hoisting equipment caused by the wall panel hoisting ropes not being vertical.

[0016] In addition, the present invention arranges the left and right threaded rods to be able to slide synchronously and reciprocally in the same direction along the axial direction, and the left and right threaded rods rotate simultaneously during sliding, so that the position of the lifting ring relative to the hanger can be kept fixed, while the position of the lifting ring relative to the left and right threaded rods changes, that is, the force point between the lifting ring and the threaded rod can be switched, thereby preventing the two threaded rods from being worn or bent due to the lifting ring always staying at the same position of the threaded rod.

[0017] Furthermore, the present invention utilizes a hydraulic push rod to push the hanging beam forward and backward, and can make slight adjustments to the front and rear positions of the hanging beams in the front and rear directions, thereby improving the position accuracy of the wall panels in the front and rear directions.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] An embodiment of a wall panel hoisting device of the present invention is as follows Figures 1 to 8 As shown, the wall panel hoisting device includes a hanger 110, and a hoisting rope 114 is connected to the upper side of the hanger 110. The hoisting rope 114 is connected to the cantilever of the crane when in use. Two wall panel hoisting ropes 121 are also connected to the hanger 110. The lower ends of the two wall panel hoisting ropes 121 are respectively connected to the wall panels 120 to be hoisted when in use. When in use, the cantilever of the crane is telescopically moved up and down to carry the wall panels 120 to be hoisted.

[0030] In the present invention, the hanger 110 is connected with a hanging beam 130 extending in the left-right direction, and the upper ends of the two wall panel hoisting ropes 121 are connected to the hanging beam 130, that is, the two wall panel hoisting ropes 121 are arranged on the hanger 110 through the hanging beam 130. In the present invention, the hanging beam 130 is a channel steel structure with an inverted U-shaped cross section, and the interior of the hanging beam 130 has an installation cavity, and two threaded rods are rotatably installed in the installation cavity, namely a left threaded rod 161 and a right threaded rod 160, and the axis extension directions of the left threaded rod 161 and the right threaded rod 160 are consistent with the extension direction of the hanging beam 130. The left threaded rod 161 and the right threaded rod 160 are respectively connected to the rotation driving device, and the rotation driving device is used to drive the left threaded rod 161 and the right threaded rod 160 to rotate. The upper ends of the two wall panel hoisting ropes 121 are provided with a lifting ring 122. In this embodiment, the lifting ring 122 is wound by the upper ends of the wall panel hoisting ropes 121. In other embodiments, a metal ring may be additionally connected to the upper ends of the wall panel hoisting ropes 121. The lifting rings 122 at the upper ends of the two wall panel hoisting ropes 121 are respectively sleeved on the left threaded rod 161 and the right threaded rod 160. The outer peripheries of the left threaded rod 161 and the right threaded rod 160 are provided with thread grooves 162. The lifting rings 122 are respectively located in the thread grooves 162. When the rotating driving device drives the left threaded rod 161 and the right threaded rod 160 to rotate, the lifting rings 122 at the upper ends of the two wall panel hoisting ropes 121 move in the left and right directions respectively to adjust the distance between the two wall panel hoisting ropes 121. In addition, the lower side of the hanging beam 130 has a through groove extending in the left and right directions, and the through groove is used for the two wall panel hoisting ropes 121 to move left and right.

[0031] In this embodiment, the left threaded rod 161 and the right threaded rod 160 are respectively movably installed in the installation cavity along the left and right directions, and the opposite ends of the left threaded rod 161 and the right threaded rod 160 are respectively connected with hydraulic drive mechanisms 136, and the hydraulic drive mechanisms 136 are respectively used to drive the left threaded rod 161 and the right threaded rod 160 to move synchronously in the same direction. Specifically, in this embodiment, the hydraulic drive mechanism 136 includes a hydraulic cylinder body 140 fixed in the middle of the installation cavity of the hanging beam 130, and the left and right ends of the hydraulic cylinder body 140 respectively have a left chamber 144 and a right chamber 142, and the left chamber 144 and the right chamber 142 are separated by a partition 143. The right end of the left threaded rod 161 is sealed and slidably installed in the left chamber 144, and the left end of the right threaded rod 160 is sealed and slidably installed in the right chamber 142. A left cylinder and a right cylinder 138 are fixed to the upper side of the suspension beam 130, respectively. The left cylinder is connected to the left chamber 144 through a left oil pipe, and the right cylinder 138 is connected to the right chamber 142 through a right oil pipe 137. When one of the left cylinder and the right cylinder 138 supplies oil to the hydraulic cylinder body 140, the other one draws oil from the hydraulic cylinder body 140 to drive the left threaded rod 161 and the right threaded rod 160 to move synchronously to the left or right.

[0032] In this embodiment, when the hydraulic drive mechanism 136 drives the left threaded rod 161 and the right threaded rod 160 to move, the rotation drive device drives the left threaded rod 161 and the right threaded rod 160 to rotate respectively, and satisfies that the position of the lifting ring 122 relative to the hanger 110 remains unchanged, while the position of the lifting ring 122 relative to the two threaded rods changes, thereby switching the relative positions of the two wall panel lifting ropes 121 on the left threaded rod 161 and the right threaded rod 160. By switching the positions of the wall panel lifting ropes 121 on the two threaded rods, the force point between the lifting ring 122 and the threaded rod can be switched, thereby preventing the threaded rod from being worn or bent due to the lifting ring 122 always staying at the same position on the threaded rod.

[0033] In this embodiment, the rotation drive device is a drive motor 132, and a spline shaft 133 is connected to the motor shaft of each drive motor 132. The opposite ends of the left threaded rod 161 and the right threaded rod 160 are respectively provided with a spline hole 163, and each spline shaft 133 is respectively inserted into the spline hole 163, and the spline shaft 133 can move along the axial direction of the spline hole 163. When the two drive motors 132 drive the spline shaft 133 to rotate respectively, the two spline shafts 133 drive the left threaded rod 161 and the right threaded rod 160 to rotate respectively, and at the same time, the hydraulic mechanism also drives the left threaded rod 161 and the right threaded rod 160 to move axially respectively, so as to ensure that the position of the lifting ring 122 on the two wall panel lifting ropes 121 relative to the hanger 110 remains unchanged, while the position of the lifting ring 122 relative to the left threaded rod 161 and the right threaded rod 160 changes.

[0034] In this embodiment, in order to ensure that the lifting ring 122 stays stably at the set position of the left threaded rod 161 and the right threaded rod 160, the left threaded rod 161 and the right threaded rod 160 are respectively sleeved with a limiting sleeve 150, and the inner wall of each limiting sleeve 150 is respectively provided with a limiting groove 151 for accommodating the corresponding lifting ring 122, and the lower part of each limiting groove 151 passes through the inner wall of the limiting sleeve 150, so that the lower end of the lifting ring 122 extends out of the limiting sleeve 150 and is connected to the wallboard lifting rope 121, and when the lifting ring 122 moves left and right along the threaded rod, it can drive the limiting sleeve 150 to move synchronously. A telescopic stop rod 153 is respectively provided on the outer wall of each limiting sleeve 150, and a limiting tooth 135 for cooperating with the telescopic stop rod 153 is provided on the inner wall of the installation cavity, and there are a plurality of limiting teeth 135. When the two wall panel hoisting ropes 121 are moved to the set position, that is, the distance between the two wall panel hoisting ropes 121 is determined, the telescopic stopper 153 is controlled to extend and cooperate with the stopper teeth 135 at the corresponding position to limit the position of the lifting ring 122 and prevent the lifting ring 122 from accidentally sliding left and right during the lifting of the wall panel 120. In addition, in order to reduce the friction between the lifting ring 122 and the thread groove 162, a lubricating oil chamber 152 is provided in each limit sleeve 150, and the lubricating oil chamber 152 is used to provide lubricating oil to the lifting ring 122.

[0035] In this embodiment, in order to improve the strength of the hanger 110 and the hanging beam 130, the hanger 110 is a rectangular frame, which includes two front and rear cross beams and two left and right longitudinal beams 111. The two cross beams and the two longitudinal beams 111 are connected end to end to form the rectangular frame, and the left and right ends of the hanging beam 130 are respectively connected to the left and right longitudinal beams 111. Two lifting ears 113 are respectively provided on the front and rear cross beams, and the lifting rope 114 is connected to each lifting ear 113.

[0036] The suspension beam 130 is a channel steel structure with an inverted U-shaped cross section. The suspension beam 130 includes a front side plate, a rear side plate, a top plate 131, and a left end plate and a right end plate. The hydraulic cylinder body 140 is fixed between the front side plate and the rear side plate by fastening bolts 141. The left oil cylinder and the right oil cylinder 138 are respectively fixed on the upper side of the top plate 131. Two driving motors 132 are respectively fixed on the left end plate and the right end plate of the suspension beam 130. The lower ends of the front side plate and the rear side plate are respectively provided with a front stop edge and a rear stop edge. The through groove is formed between the front stop edge and the rear stop edge for the two wall panel hoisting ropes 121 to move left and right. At the same time, the lower side of the limiting sliding sleeve 150 contacts the front stop edge and the rear stop edge, and the front stop edge and the rear stop edge support the limiting sliding sleeve 150. In this embodiment, in order to improve the stability of the limiting sleeve 150, guide rails extending in the left and right directions are respectively provided on the inner walls of the front side plate and the rear side plate of the suspension beam 130, and guide grooves cooperating with the guide rails are respectively provided on the front and rear sides of the limiting sleeve 150. The stability of the limiting sleeve 150 is improved by the guiding cooperation of the guide rails and the guide grooves.

[0037] In this embodiment, the upper sides of the two longitudinal beams 111 are respectively provided with ball slide rails 134 extending in the front-to-back direction, and the left and right ends of the suspension beam 130 are respectively movably connected to the two longitudinal beams 111 through the ball slide rails 134. At least one end of the two longitudinal beams 111 is respectively provided with a hydraulic push rod 112. In this embodiment, the front and rear ends of the two longitudinal beams 111 are both provided with a hydraulic push rod 112, and the hydraulic push rod 112 is connected to one end of the suspension beam 130, and is used to drive the suspension beam 130 to move in the front-to-back direction.

[0038] When a wall panel hoisting device of the present invention is used, the hoisting rope 114 is connected to the cantilever of the crane. Before hoisting the wall panel 120, the driving motors 132 on both sides are started first, and then the spacing between the two wall panel hoisting ropes 121 is adjusted to adapt to the width of the wall panel 120 to be hoisted. Then the telescopic blocking rod 153 is controlled to extend and cooperate with the limiting teeth 135 to stop. Then the lower ends of the two wall panel hoisting ropes 121 are connected to the upper ends of the wall panel 120, and the cantilever of the crane is started to hoist the wall panel 120. After the wall panel 120 is hoisted in place, if there is a misalignment between the wall panel 120 and the ground bolt below, the telescopic blocking rod 153 can be controlled to retract to release the restriction on the limiting sliding sleeve 150, and then the positions of the two wall panel hoisting ropes 121 are finely adjusted to adjust the position of the wall panel 120.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
