Description

Technical Field

[0001] This application relates to the field of slope protection construction technology, and particularly to a hoisting device for a steel reinforcement cage of a large-diameter anti-slide pile and an installation method thereof. Background Art

[0002] An anti-slide pile is a pile column that penetrates through a landslide mass and extends deep into the sliding bed, mainly used to resist the sliding force of the landslide mass and stabilize the slope. It is currently the main treatment method for shallow and medium-thick landslides. When an anti-slide pile is in use, it will bear relatively large pressure from the landslide mass. Therefore, in order to enable the anti-slide pile to bear the load, the lower end of the anti-slide pile is connected to a stable rock stratum by means of anchoring or the like to reduce the possibility of the anti-slide pile sliding with the landslide mass.

[0003] In the prior art, during the construction of an anti-slide pile, it is often necessary to first excavate the pile hole of the anti-slide pile until it reaches the stable rock stratum, then place the steel reinforcement cage into the pile hole, and finally pour concrete in the pile hole to form the anti-slide pile.

[0004] Based on the above, the inventor found that due to the slope surface used for the anti-slide pile, the forces on both sides of the anti-slide pile body are uneven. Therefore, the number of steel bars used on the side of the anti-slide pile facing the soil is much more than that on the side facing the air, resulting in uneven weight of the overall steel reinforcement cage. When hoisting the steel reinforcement cage into the corresponding pile hole, it is difficult to align the center of the steel reinforcement cage with the center of the pile hole. Summary of the Invention

[0005] In order to improve the convenience of aligning the center of the steel reinforcement cage for the anti-slide pile with the center of the pile hole, this application provides a hoisting device for a steel reinforcement cage of a large-diameter anti-slide pile and an installation method thereof.

[0006] In a first aspect, the hoisting device for a steel reinforcement cage of a large-diameter anti-slide pile provided by this application adopts the following technical solution:

[0007] A hoisting device for a steel reinforcement cage of a large-diameter anti-slide pile includes a plurality of hoisting parts, a plurality of first bearing beams, and a plurality of second bearing beams;

[0008] The plurality of hoisting parts are arranged in a circumferential distribution;

[0009] The plurality of first bearing beams are circumferentially distributed between the plurality of hoisting parts, and both ends are respectively connected to two adjacent hoisting parts;

[0010] The plurality of second bearing beams are staggeredly distributed between the plurality of hoisting parts, and both ends are respectively connected to two opposite hoisting parts;

[0011] The axes of the plurality of first bearing beams, the axes of the plurality of second bearing beams, and the centers of gravity of the plurality of hoisting parts are located in the same plane to form a hoisting plane;

[0012] The intersection points of several of the second bearing beams are eccentric to the center of the hoisting plane; the weights on both sides of the center of the hoisting plane are not set to be the same.

[0013] By adopting the above technical solution, since the intersection points of several second bearing beams are eccentric to the center of the hoisting plane, when the steel reinforcement cage is hoisted by the hoisting equipment of the present application, the steel reinforcement cage and the hoisting part are connected by straps, and then the heavier side of the hoisting plane weight is aligned with the side of the steel reinforcement cage facing the air (i.e., the lighter side of the steel reinforcement cage weight), so as to achieve the center of gravity balance of the eccentric steel reinforcement cage during hoisting, thereby maintaining the axis of the eccentric steel reinforcement cage to return to the vertical direction; when an external hoisting equipment is used to hoist the steel reinforcement cage, the hoisting equipment can be connected to the side of the hoisting plane close to the intersection of several second bearing beams, so as to improve the vertical state of the steel reinforcement cage when aligning with the pile hole, thereby enhancing the convenience of aligning the center of the steel reinforcement cage for anti-slide piles with the center of the pile hole.

[0014] Optionally, a first cable member for hanging a hoisting equipment and a second cable member for hanging on the steel reinforcement cage are provided on the hoisting part; the first cable member and the second cable member are symmetrically arranged on both sides of the hoisting plane.

[0015] By adopting the above technical solution, the first cable member and the second cable member are used to realize the connection between the hoisting equipment, the steel reinforcement cage and the hoisting equipment, so as to improve the convenience during hoisting the steel reinforcement cage.

[0016] Optionally, the first cable member includes a cable sling detachably connected to the hoisting part and a cable steel wire rope connected to the cable sling; a steel wire loop is provided at one end of the cable steel wire rope away from the cable sling; the cable sling is hinged to the hoisting part.

[0017] By adopting the above technical solution, during hoisting, the connection between the hoisting part and the hoisting equipment is realized through the cable steel wire rope, and the steel wire loop can be hooked by the hook part of the hoisting equipment. The cable steel wire rope and the steel wire loop are both made of steel wire to improve the service life of the first cable member;

[0018] The cable sling and the hoisting part are hinged to reduce the hard contact between the cable sling and the hoisting part during hoisting, and at the same time, it is also convenient to adapt to the hoisting of steel reinforcement cages in different states.

[0019] Optionally, a counterweight assembly is slidably arranged on the second bearing beam, and a pushing assembly is further arranged on the second bearing beam. The output end of the pushing assembly is connected to the counterweight assembly. The pushing assembly is used to drive the counterweight assembly to reciprocate along the length direction of the second bearing beam; the counterweight assembly is used to adjust the position of the center of gravity of the hoisting plane.

[0020] By adopting the above technical solution, in order to adapt to steel reinforcement cages of different sizes, a jacking assembly is provided to drive the counterweight assembly to slide, so as to adjust different center-of-gravity positions during hoisting according to different steel reinforcement cages, thereby improving the adaptability of the hoisting equipment.

[0021] Optionally, it further includes a center-of-gravity detection platform and a remote control assembly;

[0022] The center-of-gravity detection platform is used to detect and feedback the weights of various parts of the steel reinforcement cage;

[0023] The signal input end of the remote control assembly is communicatively connected to the center-of-gravity detection platform, and the signal output end is communicatively connected to the control end of the jacking assembly. The remote control assembly plans the movement stroke of the jacking assembly according to the center-of-gravity position and sends the operating stroke to the jacking assembly.

[0024] By adopting the above technical solution, when docking the steel reinforcement cage into the pile hole, the steel reinforcement cage needs to be adjusted to a vertical state and placed on the center-of-gravity detection platform. Then, the center-of-gravity detection platform feedbacks the overall weight distribution of the steel reinforcement cage. Based on the weight of the steel reinforcement cage feedback by the center-of-gravity detection platform, the remote control assembly implements the planning of the movement stroke of the jacking assembly and sends the planned movement stroke to the jacking assembly, so that the jacking assembly can perform corresponding actions according to the operating stroke to achieve the center-of-gravity adaptability adjustment of the hoisting plane.

[0025] Optionally, the counterweight assembly includes a sliding seat slidably connected to the second bearing beam, and a counterweight block detachably connected to the side of the sliding seat away from the second bearing beam; the output end of the jacking assembly is connected to the side of the sliding seat, and a counterweight groove is recessed in the sliding seat, and at least one of the counterweight blocks can be buckled into the counterweight groove.

[0026] By adopting the above technical solution, when it is necessary to adjust the center-of-gravity position of the hoisting plane, the jacking assembly is started to drive the sliding seat to slide along the second bearing beam, thereby driving the counterweight block to slide synchronously, so as to realize the movement of the center of gravity of the hoisting plane; the counterweight block is installed in the counterweight groove to further improve the connection stability between the counterweight block and the sliding seat; and more than one counterweight block can be placed in the counterweight groove, and the corresponding number of counterweight blocks can be placed according to actual needs to adjust the center of gravity of the hoisting plane.

[0027] Optionally, an avoidance surface is inclinedly arranged on the sliding seat, and the avoidance surface can be abutted against the side wall of the adjacent sliding seat.

[0028] By adopting the above technical solution, since the second bearing beams are arranged in a staggered manner, when the jacking assembly drives the sliding seat to slide towards the staggered position of the second bearing beams, the inclined avoidance surface can increase the movement stroke of the sliding seat, and in addition, it can reduce the loss caused by the direct impact of adjacent sliding seats.

[0029] Optionally, a detection member is provided on the avoidance surface, and the detection member is used to monitor the distance between two adjacent sliding seats; the detection member is communicatively connected to the control end of the pushing assembly; when the distance between two adjacent sliding seats is less than a threshold distance, the pushing assembly stops pushing the sliding seat.

[0030] By adopting the above technical solution, the distance between two adjacent sliding seats is detected based on the detection member, so as to facilitate the intelligent control of the real-time movement stroke of the pushing assembly by the remote control assembly.

[0031] In a second aspect, a method for installing a steel reinforcement cage for a large-diameter anti-slide pile provided by the present application adopts the following technical solution:

[0032] A method for installing a steel reinforcement cage for a large-diameter anti-slide pile includes the following steps:

[0033] Obtain the overall weight of the steel reinforcement cage to be hoisted;

[0034] Analyze the centroid position L1 based on the overall weight of the steel reinforcement cage;

[0035] Adjust the centroid position L2 of the hoisting plane based on the centroid position L1 of the steel reinforcement cage;

[0036] Judge whether the central axis of the steel reinforcement cage is parallel to the axis of the pile hole;

[0037] If so, start to dock the steel reinforcement cage into the corresponding pile hole.

[0038] By adopting the above technical solution, before docking the steel reinforcement cage into the pile hole, the weight distribution of the whole steel reinforcement cage is obtained to facilitate the analysis of the centroid position L1 of the whole steel reinforcement cage; then the hoisting equipment is moved above the steel reinforcement cage, and the centroid position L2 of the hoisting equipment is adjusted according to the eccentric centroid position L1 of the steel reinforcement cage. Subsequently, the hoisting equipment is started, and the axis of the steel reinforcement cage is kept in a state tending to be vertical. At this time, it can be judged by an external device whether the steel reinforcement cage can perform the docking action. If so, continue to start the hoisting equipment to facilitate the vertical steel reinforcement cage to be hoisted into the pile hole.

[0039] Optionally, before the step of obtaining the steel reinforcement cage to be hoisted, the following steps are further included:

[0040] Install a centroid detection platform;

[0041] Judge whether the plane of the centroid detection platform is perpendicular to the axis of the pile hole;

[0042] If so, start to execute the step of obtaining the overall weight of the steel reinforcement cage to be hoisted.

[0043] By adopting the above technical solution, the center of gravity detection platform is pre-installed and the surface of the center of gravity detection platform is kept perpendicular to the axis direction of the pile hole, so as to facilitate the execution of the subsequent steps of obtaining the weight of the steel reinforcement cage, and at the same time improve the data accuracy of obtaining the weight of the steel reinforcement cage.

[0044] In summary, the present application includes at least one of the following beneficial technical effects:

[0045] 1. When the steel reinforcement cage is hoisted by the hoisting equipment of the present application, the steel reinforcement cage and the hoisting part are connected by a strap, and then the heavier side of the hoisting plane is aligned with the side of the steel reinforcement cage facing the air (i.e., the lighter side of the steel reinforcement cage), so as to achieve the center of gravity balance of the eccentric steel reinforcement cage during hoisting, and thus maintain the axis of the eccentric steel reinforcement cage to return to the vertical direction; when an external hoisting equipment is used to hoist the steel reinforcement cage, the hoisting equipment can be connected to the side of the hoisting plane close to the intersection of several second bearing beams, so as to improve the vertical state of the steel reinforcement cage when aligning with the pile hole, and thus improve the convenience of aligning the center of the steel reinforcement cage for anti-slide piles with the center of the pile hole;

[0046] 2. In order to adapt to steel reinforcement cages of different sizes, a jacking assembly is set to drive the counterweight assembly to slide, so as to adjust different center of gravity positions during hoisting according to different steel reinforcement cages, thereby improving the adaptability of the hoisting equipment.

Detailed implementation manners

[0053] The following further describes the present application in detail with reference to Figures 1-5 the accompanying drawings.

[0054] The embodiment of the present application discloses a lifting device for a steel reinforcement cage of a large-diameter anti-slide pile.

[0055] Referring to Figure 1 and Figure 2 , a lifting device for a steel reinforcement cage of a large-diameter anti-slide pile includes a plurality of circumferentially distributed lifting parts 1, a first bearing beam 2 circumferentially distributed between adjacent lifting parts 1, and a second bearing beam 3 staggeredly distributed between two opposite lifting parts 1; wherein, both ends of the first bearing beam 2 are fixedly connected between two adjacent lifting parts 1, and a plurality of first bearing beams 2 and lifting parts 1 form a closed ring; both ends of the second bearing beam 3 are fixedly connected to two opposite lifting parts 1, and the axes of a plurality of first bearing beams 2 and second bearing beams 3 are all in the same plane as the center of gravity of the lifting part 1, thereby forming a lifting plane 4.

[0056] In order to facilitate the connection between the steel reinforcement cage and the lifting equipment; a first cable member 5 and a second cable member 6 are respectively arranged on both sides of the lifting part 1; the first cable member 5 and the second cable member 6 are symmetrically arranged on both sides of the lifting plane 4, the first cable member 5 is used to hang the lifting equipment, and the second cable member 6 is used to hang the steel reinforcement cage to be lifted, so that the lifting equipment can lift the steel reinforcement cage through the lifting device and then dock with the pile hole.

[0057] In this embodiment, the structures of the first cable member 5 and the second cable member 6 are the same.

[0058] Referring to Figure 2 and Figure 3, the first zip fastener includes a cable sling buckle 51, a cable steel wire rope 52 and a steel wire loop 53; wherein the cable sling buckle 51 is rotatably connected to the hoisting part 1, one end of the cable steel wire rope 52 is connected to the cable sling buckle 51, and the other end is fixedly connected to the steel wire loop 53, and the steel wire loop 53 and the cable steel wire rope 52 are integrally formed. The steel wire loop 53 can be hooked by a hoisting device, and at the same time, the steel wire loop 53 can also be bound to a designated position of the steel reinforcement cage.

[0059] Due to the large overall weight of the steel reinforcement cage, the cable sling buckle 51 and the hoisting part 1 are severely worn during the hoisting process. Therefore, the cable sling buckle 51 and the hoisting part 1 are detachably connected. In this embodiment, the cable sling buckle 51 includes a U-shaped buckle 511 that can be hooked on the hoisting part 1 (as shown in the figure, the sealing bolt 512 is hooked on the hoisting part 1, but actually the U-shaped buckle 511 can also be hooked on the hoisting part 1), and a sealing bolt 512 threadedly connected to the opening of the U-shaped buckle 511; the U-shaped buckle 511 is connected to the steel cable 52; the sealing bolt 512 passes through the opening of the U-shaped buckle 511 to close the opening of the U-shaped buckle 511; when hoisting the steel reinforcement cage, mainly the U-shaped buckle 511 and the hoisting part 1 are worn, and the on-site construction personnel can replace the U-shaped buckle 511 according to the degree of wear.

[0060] Refer to Figure 2 and Figure 4 , in order to facilitate the hoisting equipment to adapt to steel reinforcement cages of different sizes, a counterweight assembly 7 and a jacking assembly 8 are installed on the second bearing beam 3; the output end of the jacking assembly 8 is used to drive the counterweight assembly 7 to reciprocate along the length direction of the second bearing beam 3, so as to adjust the center of gravity position of the hoisting plane 4; the jacking assembly 8 includes two jacking devices 81, the installation of the jacking devices 81 is slidably connected to the second bearing beam 3, and the output end is fixedly connected to the counterweight assembly 7. When the jacking device 81 is started, it can drive the counterweight assembly 7 to reciprocate along the length direction of the second bearing beam 3.

[0061] The signal input end of the jacking assembly 8 is communicatively connected to a remote control assembly 9; the remote control assembly 9 is communicatively connected to a center of gravity detection platform 10; the center of gravity detection platform 10 is used to detect and feedback the weights of various parts of the steel reinforcement cage; the remote control assembly 9 calculates the center of gravity position of the steel reinforcement cage according to the weights of various parts of the steel reinforcement cage feedback by the center of gravity detection platform 10, and then plans the movement stroke of the jacking assembly 8 according to the center of gravity position and sends the operation stroke to the jacking assembly 8.

[0062] Refer to Figure 1 and Figure 4, the centroid detection platform 10 includes a horizontally laid flat plate 101, a number of strain units 102 installed on the flat plate 101, and an aggregation unit 103 communicatively connected to the number of strain units 102 at the same time; wherein, the strain units 102 are for the end of the steel cage to abut against and obtain the real-time weight data of the steel cage and send / feed back the real-time weight data to the aggregation unit 103; the position information of each strain unit 102 is preset in the aggregation unit 103, and the weight distribution of each part of the steel cage is formed based on the real-time weight information fed back by each strain unit 102, and the aggregation unit 103 sends the weights of each part of the above-mentioned steel cage to the remote control component 9.

[0063] The remote control component 9 includes a signal receiving unit 91, a signal processing unit 92, and a signal sending unit 93. Among them, the signal receiving unit 91, as the signal input end of the remote control component 9, is communicatively connected to the aggregation unit 103, and is used to receive the weight information of each part of the current steel cage and then send the weight information to the signal processing unit 92; the signal processing unit 92 calculates the centroid position L1 of the steel cage based on the weight information; calculates the centroid position L2 of the hoisting plane 4 based on the centroid position L1 of the steel cage; so as to realize that when the steel cage is lifted by a hoisting device, the centroid of the hoisting plane 4 can balance the overall axis position of the eccentric steel cage.

[0064] The signal processing unit 92 calculates the appropriate position of the counterweight assembly 7 according to the centroid position L2 of the hoisting plane 4; subsequently, the position information of the current pusher 81 can be manually input by the on-site construction personnel;

[0065] The signal processing unit 92 calculates the movement stroke of the pusher 81 (the pusher 81 pushes the counterweight assembly 7 from the current position to the appropriate position) based on the position information of the current pusher 81 and the appropriate position of the counterweight assembly 7, and then the signal sending unit 93 sends the movement stroke of the pusher 81 to the pusher 81, so that the pusher 81 drives the counterweight assembly 7 to move from the current position to the appropriate position to maintain, thereby realizing the adjustment of the centroid of the hoisting plane 4.

[0066] Refer to Figure 2 and Figure 4, the counterweight assembly 7 includes a sliding seat 71 slidably connected to the second bearing beam 3, and a counterweight block 72 detachably connected to the side of the sliding seat 71 away from the second bearing beam 3; the output end of the pusher 81 is connected to the side of the sliding seat 71, and a counterweight groove 73 is recessed in the sliding seat 71, and at least one counterweight block 72 can be buckled into the counterweight groove 73. An avoidance surface 74 is inclined on the sliding seat 71, and the avoidance surface 74 can be abutted against the side wall of the adjacent sliding seat 71. A detection member 75 is arranged on the avoidance surface 74, and the detection member 75 is used for monitoring the distance between two adjacent sliding seats 71; the detection member 75 is communicatively connected to the control end of the pushing assembly 8; when the distance between two adjacent sliding seats 71 is less than the threshold distance, the pusher 81 stops pushing the sliding seat 71.

[0067] In this embodiment, the detection member 75 can be a device with a ranging function such as a proximity switch or an infrared rangefinder.

[0068] Based on the same design concept, the embodiment of the present application also discloses a hoisting method for a steel reinforcement cage for a large-diameter anti-slide pile.

[0069] Referring to Figure 5 , a hoisting method for a steel reinforcement cage for a large-diameter anti-slide pile includes the following steps:

[0070] S100: Install the center-of-gravity detection platform 10;

[0071] Specifically, step S100 includes the following sub-steps:

[0072] S110: Lay the flat plate 101;

[0073] Specifically, the site is leveled on one side of the pile hole, and a plurality of flat plates 101 are horizontally laid on the site. Then, the construction workers recheck the position information of each strain unit 102 according to the laying position of the flat plate 101, and then fix the position of the flat plate 101; after a plurality of flat plates 101 are laid and fixed, the upper surface forms the surface of the center-of-gravity detection platform 10, and then step S120 is started to be executed.

[0074] S120: Determine whether the plane of the center-of-gravity detection platform 10 is perpendicular to the axis of the pile hole;

[0075] If so, start to execute step S200.

[0076] If not, readjust the overall levelness of the flat plate 101, and then repeat step S120.

[0077] For example, the construction workers at the construction site can use laser equipment to detect the flatness of the surface of the center-of-gravity detection platform 10 and whether the axis of the pile hole is in a vertical state.

[0078] S200: Obtain the overall weight of the steel reinforcement cage to be hoisted;

[0079] The overall reinforcement cage is adjusted to a vertical state and placed on the center of gravity detection platform 10. Each strain unit 102 obtains the current weight information of each part of the reinforcement cage and sends the weight information to the signal receiving unit 91.

[0080] S300: Analyze the center of gravity position L1 based on the overall weight of the reinforcement cage;

[0081] The signal receiving unit 91 sends the weight information to the signal processing unit 92, and the signal processing unit 92 analyzes the center of gravity position L1 of the reinforcement cage based on the weight information.

[0082] S400: Adjust the center of gravity position L2 of the hoisting plane 4 based on the center of gravity position L1 of the reinforcement cage;

[0083] The signal processing unit 92 calculates the center of gravity position L1 of the reinforcement cage based on the weight information; calculates the center of gravity position L2 of the hoisting plane 4 based on the center of gravity position L1 of the reinforcement cage; so as to realize that when the reinforcement cage is lifted by the hoisting equipment, the center of gravity of the hoisting plane 4 can balance the overall axis position of the eccentric reinforcement cage.

[0084] S500: Determine whether the central axis of the reinforcement cage is parallel to the axis of the pile hole;

[0085] If so, start to dock the reinforcement cage into the corresponding pile hole.

[0086] If not, repeat step S500.

[0087] After completing the above steps, the hoisting equipment hoists the entire hoisting plane 4 through the first cable component. Subsequently, the reinforcement cage is hoisted through the second cable component 6. Since the positions of L1 and L2 have been adjusted in advance, the reinforcement cage can be kept in a vertical state during the hoisting process, so as to maintain whether the central axis of the reinforcement cage is parallel to the axis of the pile hole. The reinforcement cage is moved to above the pile hole in a vertical state and the docking of the reinforcement cage and the pile hole is started.

[0088] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
