[0001] The utility model relates to the field of installation of waste heat boiler modules, in particular to a hoisting and flipping tool for waste heat boiler modules. Background Art

[0002] With the promotion of clean energy application in thermal power generation in recent years, waste heat boilers play a vital role in the sustainable development strategy of thermal power. The waste heat boiler modules used in gas turbine thermal power projects are numerous and arranged in the heat exchange chamber of the waste heat boiler. They include processed fin tube components, headers, tube sheets (or tube clamps), and a group of tube screens. Each part is a module composed of several separate tube screens (tube rows). The welds of the headers and tubes on each tube row are completed on the ground, and the pipe connections between the tube screens are completed on the ground. In addition, the size of a single waste heat boiler module is large, the rigidity is poor, the plate thickness is thin, and it is easy to deform. The hoisting is difficult and the hoisting cycle is long.

[0003] The traditional hoisting method is generally used in the construction of waste heat boilers. Extra-long and extra-large modules are often encountered. The double-machine lifting method is often used. It is often restricted by site limitations and it is difficult to arrange two cranes. Any slight inappropriateness in the lifting process will cause quality problems such as module tube screen damage / poor hoisting system stability / exceeding posture limit, etc.

[0004] Therefore, the problems existing in the installation of such an extra-long and extra-heavy waste heat boiler module are urgently to be solved by those skilled in the art. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a tool for quickly flipping and lifting the waste heat boiler module, which is simple to manufacture, strong and durable, easy to operate, efficient, fast, safe and reliable, reduces the use of cranes, and only requires one crane to ensure the module lifting work, thereby ensuring that the waste heat boiler module is quickly put into place, greatly reducing the consumption of manpower, materials and machines, greatly saving the cost of module lifting and placement, and improving work efficiency.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a lifting and flipping tool for a waste heat boiler module, comprising a flip frame, a lifting assembly, and a connector, the lifting assembly comprising a hanging plate and a lifting ear, the connector comprising a track groove and a lock, the flip frame comprising two main beams, a rigid frame, and a plurality of limit rods, the main beam being vertically and symmetrically fixed to one end of the rigid frame, the limit rods being vertically and correspondingly fixed to both sides of the rigid frame, a fixing rope being arranged between the corresponding limit rods, the track groove being symmetrically arranged on the inner side of the main beam, the lifting ear being arranged on the hanging plate, the hanging plate sliding in the track groove, the lock limiting the position of the hanging plate in the track groove, the waste heat boiler module being placed along the length direction of the rigid frame, the lifting end of the waste heat boiler module being connected to the hanging plate, and the limit rod limiting the position of the waste heat boiler module on the rigid frame.

The buffer transition beam is arranged at the tail of the rigid frame and is parallel to the width direction of the rigid frame. The limit beam is vertically connected to the buffer transition beam and is parallel to the main cross beam. A buffer arc is arranged on the side of the buffer transition beam away from the rigid frame and the limit beam.

DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is described below in conjunction with specific implementation methods and drawings.

[0020] like Figure 1-5 As shown, a hoisting and turning tool for a waste heat boiler module includes a turning frame 10, a hoisting assembly 20, and a connector 30. The turning frame is a main frame structure, and the waste heat boiler module 40 is limitedly installed on the turning frame. The turning frame is composed of one or more welded parts of channel steel, steel section, and angle steel. The hoisting assembly is mainly used for lifting and is connected to a crane. The connector is mainly used to connect the turning frame and the hoisting assembly, so that after the turning frame and the waste heat boiler module are in an erected state, the turning frame and the hoisting assembly are separated, and then the waste heat boiler module is lifted by the hoisting assembly alone.

[0021] The flip frame includes two main beams 11, a rigid frame 12, and a plurality of limit rods 13. The rigid frame includes two side beams 14, at least one fixed beam 15, and at least one support beam 16. The two side beams are arranged in parallel, the fixed beam is arranged in parallel between the two side beams, and the oblique support beam is arranged obliquely between the two side beams. The number of fixed beams and support beams is set according to the length of the side beams, that is, according to the length of the waste heat boiler module. Generally, there are 8 fixed beams and support beams, the fixed beams are arranged in parallel, and the support beams are cross-arranged between two adjacent fixed beams. The two main beams are arranged at the same end of the two side beams, and the main beam is vertically symmetrically fixed at one end of the rigid frame.

[0022] The limit rods are fixed vertically on both sides of the rigid frame, that is, the limit rods are installed on two side beams. According to the length of the waste heat boiler module, the limit rods are arranged in pairs in no less than four groups, and fixed ropes are arranged between the corresponding limit rods. In order to increase the fixing effect of the waste heat boiler module on the turning frame, the limit rods in the oblique direction can also use fixed ropes to assist in bundling the waste heat boiler module.

[0023] To increase the structural strength of the turning frame, the turning frame further comprises an oblique bracing beam 17, which is arranged on two sides of the turning frame, with one end of the oblique bracing beam fixed to the top of the main cross beam and the other end fixed to the side beam of the rigid frame.

[0024] The connector includes a track groove 31 and a lock 32, and the lifting assembly includes a suspension plate 21 and a lifting ear 22. The track groove is symmetrically arranged on the inner side of the main beam, and the lifting ear is arranged on the suspension plate. The suspension plate slides in the track groove, and the lock limits the position of the suspension plate in the track groove. After the waste heat boiler module is placed in the length direction of the rigid frame, the lifting end of the waste heat boiler module is connected to the suspension plate, and the limit rod limits the position of the waste heat boiler module on the rigid frame.

[0025] Furthermore, in order to prevent setbacks or overturning during the lifting process, the lifting and flipping tool also includes a tail anti-sway assembly 50, which includes a buffer transition beam 51 and a limiting beam 52. The buffer transition beam is arranged at the tail of the rigid frame and is parallel to the width direction of the rigid frame. The limiting beam is vertically connected to the buffer transition beam and is parallel to the main cross beam. A buffer arc 53 is arranged on the side of the buffer transition beam away from the rigid frame and the limiting beam. Two limiting beams are arranged, and the distance between the two limiting beams is less than the width of the buffer transition beam.

[0026] Furthermore, in order to facilitate the separation of the suspension plate from the main beam after the waste heat boiler module is in an erected state, the lifting and flipping tool also includes a slider 60, which is arranged in the track groove. The slider includes a hydraulic rod and a hydraulic pump. The hydraulic pump is fixed to the bottom of the track groove. One end of the hydraulic rod is connected to the hydraulic pump, and the other end extends in the track groove. Under the action of the hydraulic pump, the hydraulic rod pushes the suspension plate in the track groove to slide outward in the track groove, thereby completing the separation of the suspension plate from the main beam.

[0027] Specifically, when the waste heat boiler module is hoisted and erected, the waste heat boiler module is first fixed to the turning frame through the hanging plate, and then the crawler crane is used as the main hoisting point on the top of the waste heat boiler module to erect the waste heat boiler module and the turning frame. When hoisting, the hook is gradually raised, and the hook head and wire rope are kept vertical to the ground. The whole hoisting process is directed by a dedicated person, and the hoisting is stopped when the angle between the waste heat boiler module and the ground is close to 90°.

[0028] Remove the bolts connecting the flip frame and the suspension plate, and separate the flip frame and the suspension plate. At this time, the waste heat boiler module is only supported by the lifting assembly, which is connected to the lifting beam. The vertical fixture is removed as a separate component. After the flip frame is separated from the lifting assembly, the crawler crane lifts the waste heat boiler module on the lifting assembly into place.

[0029] The above embodiments are only for illustrating the structural concept and features of the utility model, and their purpose is to enable ordinary technicians in the field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the essence of the content of the utility model should be included in the protection scope of the utility model.
