Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water tower hoisting, in particular to a water tower prefabricated water tank steel structure hydraulic lifting frame. BACKGROUND

[0002] At present, in the water tower engineering construction, the water tank body structure is often faced with the problem of water tank construction before the completion of the construction of the water tower cylinder structure. Under the premise that the water tower itself does not have related devices to lift the water tank to the design height, the water tank is prefabricated by ground formwork, and the structural strength reaches the design requirement. In order to ensure that the water tank can be lifted by hydraulic pressure and safely and accurately reach the design position, the steel structure hydraulic lifting frame is required to complete the overall lifting and lifting of the water tank, so as to ensure that the water tank accurately reaches the design position for the construction of the lower process, and the construction quality of the water tank meets the requirements of the technical specification.

[0003] The conventional method for the water tank of the water tower is to wait until the construction of the water tower cylinder structure is completed, to erect a full-enclosure scaffold around the water tower cylinder structure to the design elevation of the water tank body structure, to arrange the outer formwork of the water tank structure, and to subsequently construct the water tank body structure. The above conditions can only be met when the water tower cylinder structure is completely constructed, so that the time for the subsequent process intervention is late, the construction period is prolonged, the construction cost is increased, and the water tower engineering generally has a high water tank structure full-enclosure scaffold formwork height, which is difficult to construct and difficult to ensure safety. SUMMARY

[0004] The purpose of the present application is to solve the problems in the prior art. Therefore, a water tower prefabricated water tank steel structure hydraulic lifting frame is proposed, which can solve the problem of lifting the water tank after prefabrication by ground under the premise that the water tower itself does not have a water tank hydraulic lifting system. The selected material is economically reasonable, the overall steel structure hydraulic lifting frame structure is safe and reliable, the construction cost is reduced, and the construction period of the project is saved.

[0005] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0006] A water tower prefabricated water tank steel structure hydraulic lifting frame, comprising a lifting frame support leg arranged at the top of a water tower stand and a hydraulic jack lifting frame arranged at the top of the lifting frame support leg, the lifting frame support leg is arranged in an inverted conical structure, the hydraulic jack lifting frame comprises two combined channel steel frames arranged in an upper and lower manner, hydraulic jacks are arranged between the two combined channel steel frames, steel strand insertion areas are arranged on the two combined channel steel frames, and self-made anchors for anchor steel strands when the hydraulic jacks lift the combined channel steel frames are arranged on the two combined channel steel frames, an operating platform is installed on the inner side of the lower combined channel steel frame, the operating platform is composed of a secondary beam and a horizontal radial support, angle steel supports are arranged on the horizontal radial support, and horizontal angle steel arm rods are installed at the top of the angle steel supports, and a horizontal angle steel fence is arranged at the free end of the horizontal angle steel arm rods.

[0007] By adopting the above scheme, the combined channel steel frame of the lifting track is lifted by the hydraulic jack, the steel strand is recovered by two self-made anchors with different actions, and then the lifting action of the water tank structure prefabricated on the ground is completed, and the horizontal angle steel fence, horizontal angle steel arm rod and angle steel support are used to avoid the winding of the steel strand used for lifting the water tank during the lifting of the water tank.

[0008] On the basis of the above scheme, the following improvements are made: the lifting frame support leg is arranged on the water tower top column at an angle of 75° with the horizontal plane, and the angle steel support, horizontal angle steel arm rod and horizontal angle steel fence form a steel strand traction rod.

[0009] By adopting the above scheme, the outer extension of the support leg top to the periphery of the water tower at an angle of 75° with the horizontal plane causes the steel strand to be distributed in an inverted cone shape, preventing shaking during lifting and allowing only vertical lifting along the water tower, thereby avoiding bumps during lifting.

[0010] On the basis of the above scheme, the following improvements are made: each self-made anchor includes a body and a clamping piece, the body is provided with a conical passage for the free passage of the steel strand, the outer side of the clamping piece is provided with a limiting plate, and the side wall of the limiting plate is pre-buried with an elastic expansion rod for connecting the clamping piece, the end of the elastic expansion rod is slidably connected to the side of the clamping piece through a ball head structure, the clamping piece moves radially relative to the limiting plate, and the limiting plate and the body are connected by a flexible connecting body.

[0011] On the basis of the above scheme, the following improvements are made: the limiting plate and the body are each provided with a T-shaped connecting groove for connecting the flexible connecting body.

[0012] On the basis of the above scheme, the following improvements are made: the flexible connecting body includes a connecting head that can enter the corresponding T-shaped connecting groove and a connecting part that connects the two connecting heads, and the connecting part is made of a thin sheet structure of high-strength polyurethane elastic material. This structure and material can only allow the connecting head to be installed in one direction and cannot be reversed, and when the steel strand separates from the clamping piece, the clamping piece and the anchor will not separate as a whole, avoiding the need for manual alternation of the clamping pieces of the upper and lower anchors when using traditional anchors, which is complex and sometimes causes the clamping pieces to jam. The self-made anchor does not have the above-mentioned problems, and when the steel strand and the corresponding clamping piece separate, the connecting part will automatically separate the clamping piece from the conical passage and move upward.

[0013] On the basis of the above scheme, the following improvements are made: the connecting head includes an inner connecting part and an outer connecting part, the end of the inner connecting part and the outer connecting part is connected by an end connecting part, and an internal connecting part is arranged between the outer connecting part and the inner connecting part, and the inner connecting part, the outer connecting part, the end connecting part and the internal connecting part are all made of steel sheets.

[0014] In the lifting action of the prefabricated water tank structure, when the hydraulic jack lifts the combined channel steel of the upper track, the self-made anchor of the upper track moves to the middle part relative to the limiting plate under the action of the clamping piece in the conical channel, and finally clamps the steel wire while the connecting part is bent and deformed, the limiting plate and the body are in abutment. At the same time, the self-made anchor of the lower track will move outward relative to the limiting plate while the steel strand goes up, and finally the steel wire will be loosened while the connecting part is elastically reset, the limiting plate and the body are separated. When the hydraulic jack is retracted, the self-made anchor of the lower track moves to the middle part relative to the limiting plate under the action of the clamping piece in the conical channel, and finally clamps the steel wire while the connecting part is bent and deformed, the limiting plate and the body are in abutment. At the same time, the self-made anchor of the upper track will move outward relative to the limiting plate while the steel strand goes up, and finally the steel wire will be loosened while the connecting part is elastically reset, the limiting plate and the body are separated. The reciprocating cycle completes the lifting work of the prefabricated water tank structure.

[0015] A water tower prefabricated water tank lifting method adopts the lifting frame as described above, and the lifting steps are as follows:

[0016] Step one, lay the lifting frame support legs on the water tower top column:

[0017] After the water tower cylinder structure construction is completed, the number and setting position of the lifting frame support legs are determined according to the actual design of the cylinder structure top column number and setting position of the water tower, and the length of the lifting frame support legs is determined according to the actual diameter of the water tower cylinder. The lifting frame support legs are arranged on the water tower top column at an angle of 75° to the horizontal plane, and the inclined supports between adjacent lifting frame support legs are welded and installed;

[0018] Step two, set the hydraulic jack lifting frame:

[0019] After setting the lifting frame support legs according to the actual diameter of the water tower cylinder, two identical combined channel steel frames are arranged around the top surface of all support legs, and hydraulic jacks are installed between the combined channel steel frames. The inside of the lower combined channel steel frame is welded with an operating platform composed of secondary beams and horizontal radial supports. Corresponding number of angle steel supports, horizontal angle steel arms and a week of horizontal angle steel fences are arranged on the operating platform;

[0020] Step three, ground prefabrication of water tank structure:

[0021] The water tank structure is prefabricated on the ground by supporting the formwork, and the steel strand is pre-buried through the steel pipe;

[0022] Step four, lifting of prefabricated water tank structure:

[0023] The bottom end of the steel strand is inserted into the inserted steel pipe of the prefabricated water tank structure, and is fixed and installed by a separate anchor, the top end of the steel strand is inserted into the steel strand insertion area of the two combined channel steel frames, and the steel strand is installed by the self-made anchor, when the hydraulic jack lifts the upper combined channel steel, the self-made anchor at the top clamps the steel strand, the steel strand can freely pass through the self-made anchor at the lower layer, the hydraulic jack is retracted, the self-made anchor at the lower layer clamps the steel strand, and the steel strand can freely pass through the self-made anchor at the upper layer.

[0024] On the basis of the above scheme, the following improvements are made, in the lifting action of the prefabricated water tank structure in step four, when the hydraulic jack lifts the upper combined channel steel, the self-made anchor at the upper layer moves to the middle part relative to the limiting plate under the action of the clamping piece in the conical channel, finally clamps the steel strand, and the connecting part is bent and deformed, the limiting plate and the body are in abutment, while the self-made anchor clamping piece at the lower layer moves outward relative to the limiting plate while the steel strand goes up, finally releases the steel strand, and the connecting part is elastically reset, the limiting plate and the body are separated, when the hydraulic jack is retracted, the self-made anchor at the lower layer moves to the middle part relative to the limiting plate under the action of the clamping piece in the conical channel, finally clamps the steel strand, and the connecting part is bent and deformed, the limiting plate and the body are in abutment, while the self-made anchor clamping piece at the upper layer moves outward relative to the limiting plate while the steel strand goes up, finally releases the steel strand, and the connecting part is elastically reset, the limiting plate and the body are separated, and the lifting work of the prefabricated water tank structure is completed by reciprocating circulation.

[0025] After a single engineering construction is completed, it can be disassembled and reused, the structure is economically reasonable, and in the water tower cylinder structure construction process, the water tank structure ground prefabrication can be carried out, which greatly saves the construction period, reduces the construction cost, and improves the speed and process construction quality of the water tower construction. By adopting the method, the lifting problem of the water tank after ground prefabrication under the premise that the water tower itself does not have a water tank hydraulic lifting system can be solved. The technology is safe, reliable and simple. BRIEF DESCRIPTION OF DRAWINGS
