Description

Technical Field

[0001] This invention belongs to the field of crane technology, and in particular relates to a crawler-type hoisting equipment for wave-breaking wall construction. Background Technology

[0002] Wave walls, as key structures in hydraulic structures such as ports, breakwaters, and coastal revetments, primarily function to resist wave impacts, prevent wave overtopping, and protect the safety of facilities and personnel on land behind the waves. These walls typically utilize large, heavy, irregularly shaped precast concrete components (or "blocks"), such as T-shaped blocks, T-shaped I-shaped blocks, and fence panels, with individual units weighing tens or even hundreds of tons. Currently, crawler cranes are the main equipment used for hoisting large precast components in the construction of wave-breaking walls. With their characteristics of low ground pressure, large lifting capacity and strong adaptability to construction sites, they have shown irreplaceable advantages in soft and muddy coastal mudflats. However, in practical applications, traditional crawler hoisting equipment and construction methods have exposed many inherent defects, which seriously restrict construction efficiency, safety and project quality. These defects are mainly reflected in the following aspects. In the field of crawler cranes, truss boom structures are widely used due to their high strength and lightweight advantages. Reliable and efficient connection between the sections of the truss boom is the key to ensuring the performance and safety of the whole machine. At present, the connection of the truss boom generally adopts the pin shaft connection method. However, existing pin connection technology mainly relies on manual operation, which has the following inherent drawbacks: In existing technology, the insertion, alignment and locking of the pin shaft rely entirely on the operator to complete it manually on the ground. This process is not only labor-intensive and time-consuming, becoming an efficiency bottleneck in the assembly of the whole machine, but also poses serious safety hazards. Operators need to work in dangerous areas such as high altitudes or under heavy components, which can easily lead to mechanical injuries or falls from heights. Summary of the Invention

[0003] This invention addresses the problem that in existing technologies, the insertion, alignment, and locking of pins rely entirely on manual operation by personnel on the ground. This process is not only labor-intensive and time-consuming, becoming a bottleneck in the efficiency of the entire machine assembly, but also poses serious safety hazards. Operators must work in dangerous areas such as at heights or below heavy components, which easily leads to mechanical injuries or falls from heights. The invention proposes the following technical solution: A tracked hoisting device for constructing a wave barrier wall includes: a tracked traveling device, a rotating platform rotatably mounted on the tracked traveling device, a counterweight block for increasing the weight at the end of the rotating platform, a lifting boom connected above the rotating platform and away from the counterweight block, a connecting structure connecting the rotating platform and the lifting boom, and a hook assembly connected to the front end of the lifting boom. The crawler-type hoisting equipment for wave barrier construction also includes an automatic alignment component, which is located at the end of the boom and is used to achieve automatic positioning between the boom and the rotating platform.

[0004] As a preferred embodiment of the above technical solution, the automatic alignment component includes a mounting platform fixedly installed above the rotating platform. A linear drive structure is installed inside the mounting platform. Pins are symmetrically slidably connected inside the mounting platform. Telescopic components are installed on the opposite faces of the two pins. The same gear is connected between the opposite faces of the two telescopic components. A floating guide structure is connected to the opposite faces of the two pins. A support strip is sleeved on the outside of the pins.

[0005] As a preferred embodiment of the above technical solution, the linear drive structure includes a drive component installed at the end of the rotating platform, the output end of the drive component is connected to a lead screw, a slider is provided on the outside of the lead screw, and a rack is connected to the outside of the lead screw through the slider.

[0006] As a preferred embodiment of the above technical solution, the bottom end face of the rack and the middle of the top of the rotating platform are in contact with each other, the outer side of the rack and the outer surface of the gear mesh with each other, and the rack is connected to the telescopic member through the gear.

[0007] As a preferred embodiment of the above technical solution, the floating flow guide structure includes a high-rigidity rubber-metal composite bushing connected to the end of the pin shaft. A conical sleeve is connected to the end of the high-rigidity rubber-metal composite bushing away from the pin shaft. A ball is connected inside the conical sleeve, and the conical sleeve is movably connected to the pin shaft through the ball.

[0008] As a preferred embodiment of the above technical solution, an oil inlet channel is provided on the outer side of the pin shaft, the outlet of the oil inlet channel is located on the outer side of the ball, and a piston is provided inside the oil inlet channel.

[0009] As a preferred embodiment of the above technical solution, triangular strips are fixedly connected at equal intervals to the outer side of the pin shaft near the gear, and a number of triangular grooves are opened inside the support strip. The number of triangular grooves and triangular strips corresponds one-to-one, and the support strip and the pin shaft are connected by triangular strips and triangular grooves.

[0010] As a preferred embodiment of the above technical solution, a baffle plate is fixedly installed at one end of the pin shaft near the gear, and several sets of telescopic structures are provided between the baffle plate and the opposite surface of the gear.

[0011] As a preferred embodiment of the above technical solution, the support bar is restricted from circumferential rotation but can move axially through the cooperation of the triangular bar and the triangular groove. When the telescopic member is activated, it can drive the barrier plate and the pin fixed thereto to move axially as a whole.

[0012] As a preferred embodiment of the above technical solution, a traction component is also connected between the lifting boom and the rotating platform to increase the traction force at the head of the lifting boom.

[0013] The beneficial effects of this invention are as follows: (1) The entire alignment, insertion and locking process is completed by automatic drive, which completely avoids the dangerous environment of operators being exposed to heavy parts or working at height, and fundamentally eliminates mechanical injury and fall from height accidents. (2) By hydraulically driving the automatic advancement of the pin shaft, and combined with its front-end floating guide structure, the pin shaft has radial self-centering capability, which can automatically compensate for the coaxiality deviation of the pin hole, realize rapid and accurate insertion, shorten the traditional manual operation of tens of minutes to minutes, and significantly break through the bottleneck of assembly efficiency. (3) Through the linear drive structure on the outside of the pin shaft, the connected lifting arm can be directly driven to swing in a small range, so that it can accurately reach the preset angle, creating the best docking conditions for the subsequent installation of accessories such as the pull plate, and realizing seamless coordination and process closure between various assembly processes.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] Example 1 This invention provides a crawler-type hoisting device for wave-breaking wall construction, such as... Figures 1 to 7 As shown, it includes: a tracked traveling device 1, a rotating platform 2 rotatably mounted on the tracked traveling device 1, a counterweight block 3 for increasing the weight at the end of the rotating platform 2, a lifting arm 5 connected above the rotating platform 2 and away from the counterweight block 3, a connecting structure 4 connecting the rotating platform 2 and the lifting arm 5, and a hook assembly 6 connected to the front end of the lifting arm 5. The crawler-type hoisting equipment for wave barrier construction also includes an automatic alignment component 7, which is located at the end of the boom 5 and is used to achieve automatic positioning between the boom 5 and the rotating platform 2.

[0018] In the existing technology, the insertion, alignment and locking of the pin 78 rely entirely on the operator to complete it manually on the ground. This process is not only labor-intensive and time-consuming, becoming an efficiency bottleneck in the assembly of the whole machine, but also poses serious safety hazards. Operators need to work in dangerous areas such as high altitude or under heavy components, which can easily lead to mechanical injury or fall from height. The entire alignment, insertion, and locking process is completed automatically, completely avoiding the danger of operators being exposed to heavy components or working at heights, thus fundamentally eliminating mechanical injuries and falls from heights. Furthermore, through the automatic advancement of the hydraulically driven pin 78, combined with its front-end floating guide structure, the pin 78 has radial self-centering capability, which can automatically compensate for the coaxiality deviation of the pin hole, achieving rapid and accurate insertion, reducing the traditional manual operation of tens of minutes to minutes, and significantly breaking through the bottleneck of assembly efficiency. Through the linear drive structure on the outside of the pin 78, the connected lifting arm 5 can be directly driven to swing in a small range, so that it can accurately reach the preset angle, creating the best docking conditions for the subsequent installation of accessories such as the pull plate, and realizing seamless collaboration and process closed loop between various assembly processes.

[0019] In use, the tracked walking device 1 drives the rotating platform 2 to a predetermined position, and then the hook assembly 6 lifts the object to be suspended. At this time, the counterweight 3 changes the center of the rotating platform 2. Meanwhile, the connecting structure 4 and the traction component 8 keep the lifting arm 5 stable. Finally, the rotating platform 2 rotates, and when the rotating platform 2 rotates, it carries the object to the predetermined position and then places it (the above is the prior art and will not be elaborated on here). Furthermore, during the installation of the boom 5 and the rotating platform 2, the boom 5 and the rotating platform 2 are automatically connected by the automatic alignment component 7. Specifically, a rotating platform 2 is rotatably connected to the top of the tracked traveling device 1. A counterweight 3 is placed on the top of the rotating platform 2. The number of counterweights 3 is set to several, and they are set in two groups, symmetrically arranged on the top of the rotating platform 2 along the center line. An automatic alignment component 7 is fixedly installed on the top of the rotating platform 2 away from the counterweight 3. A lifting arm 5 is snapped into the automatic alignment component 7. A connecting structure 4 connects the outer side of the top of the lifting arm 5 to the rotating platform 2. A traction component 8 is connected between the middle of the top of the lifting arm 5 and the middle of the top of the rotating platform 2. A hook assembly 6 is connected to the end of the lifting arm 5 away from the traction component 8. (The tracked traveling device 1, rotating platform 2, counterweight 3, connecting structure 4, lifting arm 5, hook assembly 6, and traction component 8 are all publicly disclosed structures and will not be elaborated on here.) To achieve the automatic installation between the lifting boom 5 and the rotating platform 2 as described above, the following solution is provided: Figures 3 to 6 As shown, the automatic alignment component 7 includes a mounting platform 71 fixedly installed above the rotating platform 2. A linear drive structure is installed inside the mounting platform 71. Pins 78 are symmetrically slidably connected inside the mounting platform 71. Telescopic components 77 are installed on the opposite faces of the two pins 78. The same gear 76 is connected between the opposite faces of the two telescopic components 77. A floating guide structure is connected to the opposite back faces of the two pins 78. A support strip 714 is sleeved on the outside of the pins 78.

[0020] In use, the mounting platform 71 is fixedly installed on the rotating platform 2, and then the lifting arm 5 is connected to the mounting platform 71. Next, the telescopic component 77 is activated. When the telescopic component 77 is running, it drives the pin shaft 78 to move. When the pin shaft 78 moves, it drives the floating guide structure to move. The floating guide structure first enters the pin hole of the lifting arm 5. At this time, the lifting arm 5 is guided by the floating guide structure. After being guided, the pin hole of the lifting arm 5 enters the outside of the pin shaft 78. Then, the linear drive structure is activated. When the linear drive structure is running, it drives the gear 76 to rotate. When the gear 76 rotates, it drives the support bar 714 to rotate through the telescopic component 77 and the pin shaft 78, so that the top of the support bar 714 fits with the bottom of the lifting arm 5, providing auxiliary support for the bottom of the lifting arm 5 and allowing the angle of the lifting arm 5 to be finely adjusted. Specifically, the mounting platform 71 is mounted on top of the rotating platform 2 by screws. A linear drive structure is installed inside the mounting platform 71. A through-hole is opened on one end face of the mounting platform 71. Two pins 78 are slidably connected inside the through-hole of the mounting platform 71. Telescopic components 77 (specifically, hydraulic telescopic rods) are fixedly installed on the opposite faces of the two pins 78. The same gear 76 is connected between the opposite faces of the two telescopic components 77. The movable end of the telescopic component 77 is fixedly connected to the pin 78. A placement hole is opened inside the pin 78. The movable end of the telescopic component 77 is located inside the placement hole. The fixed end of the telescopic component 77 is fixedly connected to the gear 76. A floating guide structure is installed on the opposite sides of the two pins 78. A support bar 714 is sleeved on the outside of the pin 78. Furthermore, to facilitate the rotation of gear 76, the following solution is provided: the linear drive structure includes a drive member 72 installed at the end of the rotating platform 2, the output end of the drive member 72 is connected to a lead screw 73, a slider 74 is provided on the outside of the lead screw 73, and a rack 75 is connected to the outside of the lead screw 73 through the slider 74. The bottom end face of the rack 75 and the middle of the top of the rotating platform 2 are in contact with each other, the outside of the rack 75 and the outer surface of the gear 76 mesh with each other, and the rack 75 is connected to the telescopic member 77 through the gear 76. In use, the drive unit 72 drives the lead screw 73 to rotate, the lead screw 73 rotates and drives the slider 74 to move, the slider 74 moves and drives the rack 75 to move, the rack 75 moves and drives the gear 76 to rotate, and the gear 76 rotates and drives the telescopic unit 77 to rotate. Specifically, a drive component 72 (specifically a drive motor) is installed at the end of the rotating platform 2 by screws. The output end of the drive component 72 is connected to a lead screw 73 by a key. The lead screw 73 is rotatably connected inside the rotating platform 2. A slider 74 is threadedly connected to the outside of the lead screw 73 at a position inside the rotating platform 2. A groove corresponding to the slider 74 is opened inside the rotating platform 2. The slider 74 is slidably connected inside the groove. A rack 75 is welded to the top of the slider 74. The bottom end of the rack 75 is in contact with the plane at the middle of the top of the rotating platform 2. The serrated part of the rack 75 meshes with the outer surface of the gear 76.

[0021] Furthermore, to facilitate the connection between the pin 78 and the boom 5, the following solution is provided: the floating guide structure includes a high-rigidity rubber-metal composite bushing 79 connected to the end of the pin 78, a tapered sleeve 711 connected to the end of the high-rigidity rubber-metal composite bushing 79 away from the pin 78, a ball 710 connected inside the tapered sleeve 711, and the tapered sleeve 711 is movably connected to the pin 78 through the ball 710. During use, because the pin hole of the lifting arm 5 does not correspond to the pin shaft 78, the tapered sleeve 711 is slightly offset. When the tapered sleeve 711 is slightly offset, it causes the ball 710 to rotate, which causes the high-rigidity rubber-metal composite bushing 79 to undergo axial deformation. This allows the pin hole of the lifting arm 5 to enter the outside of the pin shaft 78 along the tapered sleeve 711 and the high-rigidity rubber-metal composite bushing 79, thus achieving the connection between the two. Specifically, a circular groove is provided on the outer side of the pin 78, and a high-rigidity rubber-metal composite bushing 79 is fixedly installed inside the circular groove of the pin 78. A tapered sleeve 711 is fixedly installed at the end of the high-rigidity rubber-metal composite bushing 79 away from the pin 78, and a ball 710 is fixedly installed inside the tapered sleeve 711. A placement cavity is provided inside the pin 78, and the ball 710 is movably connected to the pin 78 through the placement cavity. Furthermore, since lubrication is required at the connection between the ball 710 and the pin 78 after prolonged use, in order to improve the rotational efficiency of the ball 710, the following solution is provided: an oil inlet channel 712 is provided on the outside of the pin 78, the outlet of the oil inlet channel 712 is located on the outside of the ball 710, and a piston is provided inside the oil inlet channel 712.

[0022] When in use, pull the piston to open the oil inlet channel 712, and then inject lubricating oil along the oil inlet channel 712. At this time, the lubricating oil enters the connection between the ball 710 and the pin 78, thereby lubricating the connection between the ball 710 and the pin 78.

[0023] To achieve the slight angular deflection of the boom 5 in the above embodiments, the following solution is provided: Triangular bars 713 are fixedly connected at equal intervals to the outer side of the pin 78 near the gear 76. Several triangular grooves 715 are opened inside the support bar 714. The number of triangular grooves 715 and triangular bars 713 corresponds one-to-one. The support bar 714 and the pin 78 are connected by triangular bars 713 and triangular grooves 715. A baffle plate 716 is fixedly installed at the end of the pin 78 near the gear 76. Several sets of telescopic structures 717 are provided between the opposing surfaces of the baffle plate 716 and the gear 76. The support bar 714 is restricted from circumferential rotation but can move axially through the cooperation of triangular bars 713 and triangular grooves 715. When the telescopic member 77 moves, it can drive the baffle plate 716 and the pin 78 fixed thereto to move axially as a whole. In use, the support bar 714 is connected to the triangular bar 713 through the triangular groove 715, so that the support bar 714 cannot rotate axially through the triangular groove 715 and the triangular bar 713. At this time, when the telescopic member 77 is running, it drives the baffle plate 716 and the pin 78 to fit against the inner wall of the mounting platform 71, and then continues to move. At this time, the reverse force of the mounting platform 71 causes the support bar 714 to move along the outside of the triangular bar 713 and move until it fits against the end face of the baffle plate 716, so that the support bar 714 is fully installed.

[0024] Specifically, several triangular strips 713 are equidistantly welded to the outer side of the pin 78 near the gear 76. Several triangular grooves 715 are formed inside the support bar 714 corresponding to one end face of the triangular strips 713. The number of triangular grooves 715 and triangular strips 713 corresponds one-to-one. The support bar 714 and the pin 78 are connected by the triangular strips 713 and triangular grooves 715. The support bar 714 is restricted from circumferential rotation but can move axially through the cooperation of the triangular strips 713 and triangular grooves 715. When the telescopic member 77 moves, it can drive the baffle plate 716 and the pin 78 fixed thereto to move axially as a whole. The baffle plate 715 is welded to the end of the pin 78 near the gear 76. 16. Several sets of telescopic structures 717 are provided between the opposing surfaces of the barrier plate 716 and the gear 76. The telescopic structure 717 is composed of two concave blocks, one I-shaped block and two rotating bars. The two concave blocks are fixedly installed on the opposing surfaces of the barrier plate 716 and the gear 76 respectively. The rotating bars are rotatably connected to the inside of the two concave blocks through round rods. The two rotating bars are rotatably connected to the same rotating bar through round rods. The shape of the telescopic structure 717 is an arch bridge and is far away from the axis of the pin 78. The telescopic structure 717 increases the connection strength between the barrier plate 716 and the gear 76, so that the gear 76 drives the barrier plate 716 to rotate synchronously through the telescopic structure 717.

[0025] Working principle: In actual use, the crawler walking device 1 runs and moves the entire equipment to the predetermined construction area. At this time, the rotating platform 2 rotates so that the mounting platform 71 on it is in a position that is easy to dock. Then, the lifting arm 5 is lifted to the top of the mounting platform 71 by the auxiliary lifting tool so that the connecting ear plate hole at the bottom of the lifting arm 5 is roughly aligned with the axis of the two pins 78. Next, after the operator confirms that the environment is safe in the cab, the automatic connection program is started. The control system first sends a command to the two telescopic components 77 hydraulic telescopic rods. The piston rod of the telescopic component 77 extends and pushes the pin 78 fixed thereto to move towards each other along the mating hole of the mounting platform 71. The pin 78 drives the floating guide structure at its front end (composed of a high-rigidity rubber-metal composite bushing 79, a ball 710 and a conical sleeve 711) to move towards the connecting ear plate pin hole of the boom 5. At this time, the tapered sleeve 711 first contacts the edge of the connecting ear plate pin hole. If there is an initial positional deviation, the tapered sleeve 711 is subjected to a radial force. This radial force forces the tapered sleeve 711 to deflect through the ball 710, while simultaneously squeezing the high-rigidity rubber-metal composite bushing 79. The elastic deformation of the bushing absorbs and compensates for the alignment error. Under the continuous axial thrust provided by the telescopic component 77, the deflected tapered sleeve 711 acts as a guide head, automatically correcting the path and guiding the entire pin 78 smoothly and accurately through the connecting ear plate pin hole of the crane arm 5 (the connecting ear plate pin hole is an existing structure on the crane arm 5). After confirming that the pin 78 has been fully inserted... The control system starts the drive unit 72 (drive motor), which drives the lead screw 73 to rotate. The slider 74, which is threadedly engaged with the lead screw 73, moves linearly in the groove of the rotating platform 2. The slider 74 drives the rack 75 to move synchronously. The rack 75 drives the gear 76 meshing with it to rotate. The gear 76, through the cooperation of the fixed end of the telescopic component 77, the pin 78, the triangular bar 713 and the triangular groove 715, finally drives the support bar 714 to rotate. The support bar 714 rotates until its top plane is tightly attached to the bottom of the lifting arm 5, forming a stable auxiliary bearing surface. By precisely controlling the rotation angle of the drive unit 72, the stepless or stepped fine adjustment of the pitch angle of the lifting arm 5 can be achieved, so that it can accurately reach the preset installation angle, which is ready for the subsequent connection of the pull plate. After the angle adjustment is completed, the system executes the final locking command. The telescopic component 77 may continue to apply a final clamping force, pushing the pin 78 and the baffle plate 716 fixed at its end, so that the internal gap of the entire connecting assembly, including the support bar 714, is completely eliminated. At this time, the inclined surface of the triangular bar 713 and the triangular groove 715 engages to form a strong circumferential self-locking, while the telescopic structure 717 provides axial support and buffering. During equipment maintenance, lubricating oil can be injected through the oil inlet channel 712. The lubricating oil is delivered under pressure to the contact surface of the ball 710 and the pin 78, ensuring that the floating guide mechanism maintains its flexibility and reliability for a long time and extending the service life of the core components.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
