Description

Technical Field

[0001] The invention relates to the field of bridge engineering and construction engineering equipment, and in particular to a reversing device, an embedded part, a lifting device and a lifting tower crane device. Background Art

[0002] Traditional tower cranes are installed on the ground to assist in the construction of bridge piers. A foundation for installing the tower cranes is also required under the ground. Traditional tower cranes are installed on the surface of the foundation. As the height of the piers increases, the height of the tower cranes increases. The number of supporting wall braces used to stabilize the connection between the tower cranes and the piers increases accordingly. Traditional tower cranes have the following shortcomings:

[0003] (1) Traditional tower crane equipment is installed and fixed on the foundation surface. As the height of the pier is gradually increased, the height of the tower crane equipment increases synchronously, and the number of wall supports also increases accordingly, thereby increasing the cost and making the tower crane equipment expensive.

[0004] (2) In traditional tower crane construction, accidents such as overturning and collapse of bridge piers due to their high height have occurred repeatedly.

[0005] (3) Traditional tower crane equipment is made up of tower sections. The higher the tower crane equipment is, the more tower sections and supporting wall supports there are, and the higher the cost of transportation, stacking and transshipment.

[0006] (4) With traditional tower crane equipment, as the height of the cast bridge pier increases, the tower sections and supporting wall supports are gradually installed upwards, and after the construction is completed, the tower sections and supporting wall supports are gradually removed downwards. The cumbersome installation, disassembly, lifting and operation result in high costs and low safety.

[0007] (5) Constructing bridge piers in harsh and high-risk geographical environments such as valleys, steep slopes, lakes, and areas with poor geology is not conducive to building foundations and seriously increases the difficulty of construction.

[0008] (6) Traditional tower crane equipment requires a foundation to be built below ground level for installing and fixing the tower crane equipment. The steel bars, concrete, excavation equipment, lifting equipment, poor geology and other factors used result in high costs for building the foundation.

[0009] (7) The higher the height of traditional tower crane equipment, the greater the requirements for material specifications, cross-sectional dimensions of the tower crane body, force, and stability, and the higher the cost.

[0010] (8) The traditional wall protection connection device includes an embedded part system and a mount; the embedded part system includes an anchor plate, an anchor rod, a climbing cone and a bolt; the mount is hung on one end of the bolt, the other end of the bolt is threadedly connected to one end of the climbing cone, the other end of the climbing cone is threadedly connected to the anchor rod, and the other end of the anchor rod is threadedly connected to the anchor plate. The traditional embedded part system connection uses a torsion component to form a fixed connection through thread engagement. The installation or disassembly of the entire wall protection connection device is complicated and inefficient. The anchor plate and the anchor rod cannot be reused after each section is constructed, resulting in material waste; the traditional wall protection connection device connection is divided into two main structure connections, one is the embedded part system for connection with concrete, and the other is the mount for connection with the equipment body; the traditional wall protection connection device is suitable for equipment that can climb, but is not suitable for lifting tower crane equipment that can not only climb but also descend.

[0044] The working principle of the fixed and sliding connection between the snap box and the guide rail in the implementation of the present invention is as follows: three inner snap sleeve components are combined into a conical inner snap sleeve, and the outer snap sleeve used in conjunction with the inner snap sleeve has a small upper part and a large lower part. The snap box and the guide rail need to apply an upward force including an upward reaction force to the inner snap sleeve when the sliding connection is converted to a fixed connection. The force-applying objects for applying an upward force to the inner snap sleeve include a spring, a spring column, and a lower push rod. When the inner snap sleeve is subjected to the upward force and moves upward relative to the outer snap sleeve, and at the same time, the outer snap sleeve moves downward relative to the inner snap sleeve, the inclined surface inside the outer snap sleeve applies a force from the outside to the central axis direction of the inner snap sleeve to the outer surface of the inner snap sleeve. The three inner sleeve components are tightened toward the central axis, the inner sleeve and the concave and convex teeth of the guide rail are engaged, and the outer sleeve moves downward relative to the inner sleeve and is stopped by the inner sleeve. At this time, the snap box and the guide rail are converted from a sliding connection to a fixed connection; when the outer sleeve moves upward relative to the inner sleeve, because the inner part of the outer sleeve is small at the top and large at the bottom, the space around the inner sleeve becomes larger and larger, and when the three inner sleeve components are subjected to upward elastic force or downward gravity, the inner surface of the inner sleeve component is subjected to the reaction force of the outer surface of the guide rail, and when the inner sleeve separates from the central axis in an outward direction, the inner sleeve component and the guide rail are converted into a sliding connection, and at this time, the snap box and the guide rail are converted from a fixed connection to a sliding connection.

[0045] Due to the adoption of the above technical solution, the present invention has the following technical effects:

[0046] (1) The lifting tower crane of the present invention casts bridge pier concrete through the formwork in the main body, and uses the cast concrete as a path for lifting. The height of the main body of the lifting tower crane of the present invention does not change with the height of the cast bridge pier, so the cost does not increase with the increase of the height of the cast bridge pier, and the cost is significantly reduced.

[0047] (2) The lifting tower crane device of the present invention has two closed platforms, the upper and lower platforms are in contact with the surface of the bridge pier in a rolling friction manner to balance the horizontal lateral force. The bottom balances the vertical force through a diagonal brace. The upper and lower platforms are also connected by a connecting rod to form a stable and closed three-dimensional frame structure to stabilize the construction of the lifting tower crane device. The stability does not change due to the change in the height of the cast bridge pier, which solves the problem of traditional tower crane equipment repeatedly causing safety accidents due to changes in stability due to excessive height.

[0048] (3) The lifting tower crane equipment of the present invention can be lifted and lowered by being attached to the bridge pier, the height of the main body remains unchanged, and the rod structure is reduced, which significantly reduces the transportation, stacking and transfer costs.

[0049] (4) The lifting tower crane device of the present invention can be lifted and lowered by being attached to a bridge pier, has a small number of rod structures, and can be assembled and disassembled using a crane on the ground, thus solving the problem of the high cost of traditional tower crane assembly and disassembly due to the large number of structural rods.

[0050] (5) The lifting tower crane device of the present invention is attached to the bridge pier for lifting and lowering, which solves the problem that traditional tower crane equipment is not conducive to the construction of foundation and seriously increases the difficulty of construction when constructing bridge piers in harsh and high-risk geographical environments such as valleys, steep slopes, lakes, and poor geology.

[0051] (6) The lifting tower crane device of the present invention is lifted and lowered by the bridge piers without using a foundation, thus solving the problem that the traditional tower crane device needs to build a foundation below the ground level for installing and fixing the tower crane device. The present invention significantly reduces the cost.

[0052] (7) The lifting tower crane equipment of the present invention can be lifted and lowered by attaching to the bridge piers, and its stability does not change with the height of the bridge piers. This solves the problem that the stability of traditional tower crane equipment changes due to changes in construction height. When the height is too high, higher cross-sectional dimensions and material specifications of the tower crane equipment are required, which seriously causes high costs.

[0053] (8) The embedded parts of the present invention are an integral whole, which can not only be pulled out from the concrete for repeated use, but also can balance the vertical force when the tower crane equipment in the lifting tower crane equipment body of the present invention is in operation; the embedded parts of the present invention are easy to carry and circulate, and are simple to assemble and disassemble; the embedded parts are preferably a plate that can form a stable and reliable connection with the concrete without translation or rotation; the embedded parts of the present invention are an integral whole with one end connected to the concrete and the other end connected to the equipment body; the embedded parts of the present invention have a single structure, which reduces the construction and material costs, and also improves the construction efficiency; the embedded parts of the present invention are suitable for lifting tower crane equipment that can not only climb but also descend.

[0054] (9) The guide rail of the present invention preferably uses finely rolled threaded steel with good tensile strength. The guide rail is light in weight and can be lifted manually to solve the lifting problem of the guide rail.

[0055] (10) The reversing device of the present invention can implement two different technical solutions, namely: driving the device body to climb and driving the device body to descend. The two solutions are interchangeable without changing the main structure of the device to ensure construction safety. BRIEF DESCRIPTION OF THE DRAWINGS

The upper and lower end plates of the movable buckle box are provided with guide grooves 11 on both sides, and the guide grooves 11 on both sides can be stuck on the column 4 on the corresponding side and slide; the climbing device includes a spring 20, a pull rope 21, a spring pad 22, and a hook 23, such as Fig. 9 As shown; the spring pad 22 is arranged below the snap box 1, the spring 20 passes through the lower end plate 601, one end of the spring 20 is arranged on the spring pad 22 and the other end is in contact with the inner sleeve pad 12, the hook 23 is arranged on the lower end plate 601, one end of the pull rope 21 is connected to the spring pad 22, and the other end of the pull rope 21 passes through the lower and upper parts of the snap box 1 (that is, through the small holes on the upper and lower end plates 601) and can be hung on the hook 23 after the spring 20 is compressed. When the spring 20 is compressed, the elastic force transmits the upward force to the bottom of the inner sleeve 5 through the inner sleeve pad 12; the guide rail 2 passes through the snap box 1 and also passes through the spring 20 and the spring pad 22; the telescope 3 in this embodiment adopts a hydraulic cylinder, also known as a hydraulic jack.

[0103] See also Fig.18The lifting device needs two sets of embedded parts 24 to climb upward. The first set of embedded parts 35 is inserted into the embedded holes 34, and the second set of embedded parts 36 is in standby. The top of the column 4 in the reversing device body is connected to the embedded part hole 27 through the first latch 29, and the top of the guide rail 2 in the reversing device body is connected to the embedded part slot 28 through the second latch 30. The pull rope 21 is not hung on the hook 23, and the spring 20 does not apply force to the inner sleeve 5, so that the guide rail 2 can be lifted upward; the second set of embedded parts 36 is inserted into the embedded holes 34 of the concrete of the section to be climbed, and the second latch 30 is pulled out to lift the guide rail 2 by manpower. This embodiment demonstrates that the lifting device hung on the first set of embedded parts 35 climbs to the second set of embedded parts 36; refer to Fig.19 , the guide rail 2 is lifted to the second set of embedded parts 36, and the top of the guide rail 2 is connected to the second set of embedded parts 36 through the second latch 30; Fig. 20 When one end of the pull rope 21 is pulled, the spring pad 22 connected to the other end is lifted upward and the spring 20 is compressed. The spring 20 applies an upward thrust to the inner sleeve 5 through the inner sleeve pad 22. The inner sleeve 5 is pushed and slid to the top of the outer sleeve 6. At this time, the spring 20 is in a compressed state. The other end of the pull rope 21 is hung on the hook 23, and then the first pin 29 is pulled out.

[0104] First, see Fig.21 , the telescopic device 3 is extended, and the movable buckle box 9 is not hindered by the inner clamping sleeve 5 in the movable buckle box 9 because the outer buckle sleeve 6 is smaller at the top and larger at the bottom. Therefore, the movable buckle box 9 slides upwards attached to the column 4 until the telescopic device 3 is fully extended;

[0105] Step 2: See Fig. 22 , the telescopic device 3 retracts. Because the outer buckle sleeve 6 of the movable buckle box 9 is smaller at the top and larger at the bottom, the inner buckle sleeve 5 in the movable buckle box 9 is pushed upward by the spring 20, and the concave-convex teeth 19 on the inner surface of the inner buckle sleeve 5 engage with the concave-convex teeth on the outer surface of the guide rail 2. The inner buckle sleeve 5 in the movable buckle box 9 cannot slide downward, preventing the movable buckle box 9 from sliding downward. The movable buckle box 9 and the guide rail 2 are converted into a fixed connection, and the telescopic device 3 continues to retract and the fixed buckle box 10 is lifted upward. Because the fixed buckle box 10 is not hindered by the inner buckle sleeve 5 in the fixed buckle box 10, the fixed buckle box 10 moves upward. Because the fixed buckle box 10 is fixedly connected to the column 4, it drives the column 4 to move upward at the same time, and the entire equipment climbs upward. After the telescopic device 3 is fully retracted, it continues to extend. At this time, it returns to the first step, and the first and second steps are repeated. The lifting device drives the entire equipment to gradually climb upward.

[0106] See also Fig.23 The lifting device stops when the first set of embedded parts 35 are pulled out from the gap between the column 4 and the guide rail 2 without hindering the lifting device to climb. After the first set of embedded parts 35 are pulled out, the lifting device continues to climb. Fig.24When the lifting device climbs to the second group of embedded parts 36, the climbing is stopped and the first latch 29 is inserted. The lifting device has completed one section of climbing.

[0107] The guide rail 2 of the present invention preferably uses φ25 finely rolled threaded steel, weighing about 4kg per meter. In this embodiment, the concrete height of each section is 4.5 meters, and the guide rail 2 is 7 meters long and weighs about 28kg. This weight is easy to lift for workers on site.

[0108] This embodiment 2 demonstrates that the embedded part 24 realizes the climbing of the lifting device on the inner side between the two columns 4. The embedded part 24 can also be set on the outer side of the two columns 4 to realize the lifting of the lifting device. The movable snap box 9 can also be set below the fixed snap box 10 to realize the climbing of the lifting device.

[0109] Embodiment 3: Implementing the step of lowering the lifting device (in the lowering step, the climbing device is not used, but the descending device is used)

[0110] In this embodiment, the lifting device in combination with Embodiment 2 of the present invention has climbed to the top of the pier and implemented the step of descending to the bottom of the pier. The lifting device of the present invention can implement two different technical solutions. The main structure is not moved when changing from a climbing device to a descending device at high altitude, otherwise a falling accident will occur.

[0111] Provide a descending lifting device, see Fig.14 and Fig.25 In this embodiment, the climbing device is removed from the lifting device structure of the second embodiment of the present invention and a descending device is installed. The descending device includes a connecting rope 15, a tension spring 16, an upper bottom plate 17, a lower bottom plate 18, a spring column 13, and a lower push rod 14; Figure 3 and Figure 4The fixed buckle box 10 shown is fixedly arranged between the two columns 4 and arranged at the lower part of the columns 4 and close to the bottom. The movable buckle box 9 is slidably arranged between the two columns 4 and located above the fixed buckle box 10. The spring column 13 used in conjunction with the movable buckle box 9 is installed on the upper bottom plate 17. The upper bottom plate 17 is detachably installed on the column 4 and is located below the movable buckle box 9; the lower push rod 14 used in conjunction with the fixed buckle box 10 is installed on the lower bottom plate 18, and the lower bottom plate 18 is located below the fixed buckle box 10. The lower bottom plate 18 is connected to the movable buckle box 9 through a connecting rope 15, and a tension spring 16 is also arranged on the connecting rope 15 (that is, the connecting rope 15 is composed of an upper and a lower section, and the tension spring 16 is arranged on the upper and lower sections). The spring column 13 comprises an outer sleeve, a spring, a piston rod and an outer sleeve cover; a limit plate is arranged at the bottom of the piston rod, a limit ring is arranged at one end inside the outer sleeve, one end of the piston rod passes through the outer sleeve, and the limit plate at the other end of the piston rod is prevented from passing through by the limit ring; the spring is installed in the outer sleeve and contacts with the limit plate, and the outer sleeve cover is installed at the other end of the outer sleeve by threaded cooperation. After the outer sleeve cover is screwed on the outer sleeve, the spring is compressed, so the piston rod can be compressed and rebounded, and the spring column 13 and the lower push rod 14 can convert the sliding connection between the inner sleeve 5 and the guide rail 2 into a fixed connection.

[0112] In combination with Example 2, a method for removing a climbing device is provided: Fig.24 The pull rope 21 with one end hung on the hook 23 is removed from the hook 23. At this time, the thrust of the spring 20 on the inner sleeve 5 is removed. The second pin 30 is pulled out, and the guide rail 2 is moved downward by the gravity until the inner sleeve 5 falls off. The guide rail 2 and the inner sleeve 5 have been converted from a fixed connection to a sliding connection. The guide rail 2 is lifted manually, and the climbing device can be easily removed after the bottom of the guide rail 2 is pulled out of the movable buckle box 9.

[0113] Steps for lowering the lifting device: In order to highlight the relationship between the lowering device and the inner sleeve 5, a section of the guide rail 2 is hidden in this embodiment. Please understand that the guide rail 2 runs through the entire reversing device; refer to Fig.25 The lifting device is connected to the embedded hole 34 through the first group of embedded parts 35, and the second group of embedded parts 36 is on standby. The movable card box 9 and the fixed card box 10 are in a fixed connection state with the guide rail 2. The spring column 13 abuts against the bottom of the inner card sleeve 5 in the movable card box 9. At this time, the telescope 3 has not been fully retracted, and the first pin 29 is pulled out.

[0114] First, see Fig.25The telescopic device 3 continues to retract and the fixed buckle box 10 is lifted upward. Because the outer buckle sleeve 6 is smaller at the top and larger at the bottom, the space around the inner buckle sleeve 5 in the fixed buckle box 10 becomes larger and larger. Finally, the inner buckle sleeve 5 composed of three inner buckle sleeve components 7 falls off downward under the action of gravity.

[0115] See also Fig.26 At this time, the fixed buckle box 10 and the guide rail 2 are converted from fixed connection to sliding connection, and the retractor 3 has been completely retracted; because the movable buckle box 9 is in fixed connection with the guide rail 2, and the fixed buckle box 10 is in sliding connection with the guide rail 2, the retractor 3 extends out of the fixed buckle box 10 and moves downward, and because the fixed buckle box 10 is fixedly connected to the column 4, the column 4 moves downward synchronously, driving the entire device to descend synchronously;

[0116] See also Fig. 27 , during the downward movement of the fixed snap box 10, the inner clamping sleeve 5 in the fixed snap box 10 is blocked by the lower push rod 14, and the inner clamping sleeve 5 in the fixed snap box 10 is compressed by the upper small and lower large space inside the outer clamping sleeve 6, and the three inner clamping sleeve components 7 are tightened toward the axis of the guide rail 2. When the inner clamping sleeve 5 in the fixed snap box 10 and the concave and convex teeth on the surface of the guide rail 2 cannot bite, the snap box 10 continues to descend, and the tension spring 16 is further stretched until the concave and convex teeth in the inner clamping sleeve 5 are misaligned with the concave and convex teeth on the outer surface of the guide rail 2 to form a bite, and the fixed snap box 10 and the guide rail 2 have been converted into a fixed connection. At this time, the telescope 3 has not been fully extended;

[0117] See also Fig.28 , the retractor 3 continues to extend, the tension spring 16 is stretched again, the movable buckle box 9 is pushed upward by the retractor 3, and the inner clamping sleeve 5 in the movable buckle box 9 falls off downward under the action of gravity, and the movable buckle box 9 is converted into a sliding connection with the guide rail 2;

[0118] Step 2: See Fig.29 , retract the telescopic device 3, the movable buckle box 9 slides downwardly attached to the column 4, and during the sliding process, the bottom of the inner clamping sleeve 5 in the movable buckle box 9 is blocked by the spring column 13 installed on the column 4 through the upper bottom plate 17, and the inner clamping sleeve 5 in the movable buckle box 9 is engaged with the concave and convex teeth of the guide rail 2 to be converted into a fixed connection. At this time, the telescopic device 3 has not been fully retracted;

[0119] See also Fig.30 The retractor 3 continues to retract and the fixed buckle box 10 is driven to lift upward, and the operation has returned to the first step.

[0120] Repeat the first and second steps continuously, and the lifting device will gradually descend. Fig.31 The lifting device stops descending when it descends to a point where it does not hinder the second set of embedded parts 36 from being inserted into the embedded holes 34 through the gap between the column 4 and the guide rail 2, and then the second set of embedded parts 36 is inserted, and the lifting device continues to descend; Fig.32, the top of the column 4 is lowered to the second set of embedded parts 36, and the first latch 29 is inserted, and then the second latch 30 at the top of the guide rail 2 is pulled out; Fig.33 The guide rail 2 is lowered to the second set of embedded parts 36 by manpower and the second latch 30 is inserted. At this time, the lifting device has been lowered from the concrete of the upper section to the lower section. Repeat the above operation steps and the lifting device gradually descends to the bottom of the pier.

[0124] Implementation steps of lifting tower crane equipment: This embodiment is to cast a bridge pier with a rectangular cross-section. A lifting device is arranged on each side of each of the four sides of the bridge pier. In addition, two lifting devices are arranged for use with the supporting tower crane equipment 40. The specific implementation is as follows:

[0125] The concrete of each section needs to reserve the embedded hole 34 through the embedded part 24. For the specific implementation of the embedded part 24, please refer to the embodiment 1 of the present invention. After the concrete of the first section reaches the demoulding strength, the template 31 is removed, and then the lifting tower crane equipment is installed using the crane equipment. Figure 34-35The lifting device is connected to the concrete through the first set of embedded parts 35, and the frame system, the tower crane 40, the template rearward moving device, and the template 31 are installed on the lifting device; the installation structure of the lifting tower crane device can refer to the lifting tower crane device described in this embodiment; Fig.36 A lifting device is arranged on each side of the tower crane, which is mainly used to bear the vertical load transmitted by the tower crane 40; the lower diagonal brace 39 is installed in the lifting tower crane body before the tower crane 40 is operated, and the lower diagonal brace 39 is mainly used to balance the vertical load transmitted by the tower crane 40 during operation; refer to Fig.37 Before lifting the tower crane equipment, the template 31 needs to be moved back by the backward moving device to form a gap with the concrete to prevent friction, and then the lower diagonal brace 39 and the embedded parts 24 connected to the lower diagonal brace 39 are removed; then the equipment body is driven to lift and lower by the lifting device of the present invention.

[0126] The present invention provides a stability solution for a lifting tower crane. The stability of the lifting tower crane includes: stability during construction and stability during lifting. (1) The stability during construction is mainly borne by the upper platform 37, the lower platform 38, the lower diagonal brace 39 and the embedded parts 24. During construction, the lifting tower crane will generate horizontal lateral force and vertical force. The horizontal lateral force is transmitted by the closed frame system to the upper and lower platforms and finally to the concrete balance. The vertical force is transmitted by the lower diagonal brace 39 to the embedded parts 24 and finally to the concrete balance. (2) The stability during lifting is transmitted by the closed frame system to the upper and lower platforms and finally to the concrete balance. The tower crane 40 is prohibited from being used during lifting. Therefore, the vertical load is relatively small compared to the load during construction. The preferred solution of the tower crane 40 in the lifting tower crane body adopts a remote control to control the operation to ensure construction safety.

[0127] The above are only implementation modes of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention specification and drawings, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present invention. In the accompanying drawings, the outer surface of the guide rail should be drawn with concave and convex teeth to match the text expression. In order to express the lifting action clearly, the guide rail without concave and convex teeth is deemed to be consistent with the text expression.
