Description

Technical Field

[0001] The utility model relates to the technical field of concrete component production machinery, in particular to a turnover machine for bridge deck system components. Background Technique

[0002] Bridge deck system components are important components of prefabricated buildings and are a type of reinforced concrete precast slab used for building railway bridges. Based on the requirements of green railway construction, in order to reduce the cast-in-place concrete work volume of simply supported beams of high-speed railways and facilitate the installation of sound barriers and side walls, etc. Currently, the fixed mold type production is generally adopted in bridge deck system component factories. After the components are demolded, they need to be turned over. The traditional turning method is to lift and turn over by a crane, and each time it can only be turned over by 90°, so two turns are required to turn over the bridge deck system components (180-degree turn), which is easy to cause damage to the appearance of the components, and the safety and efficiency are not high. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a turnover machine for bridge deck system components, which is used to solve the problems of low safety and efficiency during the turnover of current bridge deck system components.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0005] A turnover machine for bridge deck system components includes a gantry, a traveling crane that can longitudinally travel on the top of the gantry, and a turnover mechanism arranged below the traveling crane for driving the turnover of bridge deck system components; the turnover mechanism includes two mutually parallel and horizontal lifting beams, a horizontal square frame arranged between the two lifting beams, and locking mechanisms arranged on both sides of the square frame for clamping the bridge deck system components. A hoist for driving the lifting beams to move up and down is arranged on the traveling crane. The two lifting beams are respectively rotationally connected to the corresponding side of the square frame. The rotation axis of the square frame is horizontal, and a reduction motor for driving the rotation of the square frame is arranged on the lifting beam.

[0006] Further, the square frame includes two mutually parallel first side beams and two mutually parallel second side beams. The two first side beams and the two second side beams are fixedly connected to form a rectangle. The first side beams are parallel to the lifting beams, and the first side beams are respectively rotationally connected to the corresponding lifting beams. The second side beams are perpendicular to the first side beams.

[0007] Further, the locking mechanism includes a second hydraulic cylinder perpendicularly and fixedly connected to the outer side of the second side beam, a sliding sleeve perpendicularly and fixedly connected to the inner end of the second side beam, and a second bolt slidably connected in the sliding sleeve. The second bolt is fixedly connected to the second hydraulic cylinder. When the second hydraulic cylinder acts, the second bolt extends or retracts from the sliding sleeve. After the second bolt extends from the sliding sleeve, the second bolt is inserted into the corresponding hole on the side surface of the bridge deck system component.

[0008] Further, the winch drives the lifting beam to move up and down through a steel wire rope. A buffer mechanism is connected between the steel wire rope and the lifting beam. The buffer mechanism includes a vertically arranged sleeve with a closed bottom and filled with hydraulic oil, a slider slidably connected in the sleeve, a pull rod slidably connected through the bottom of the sleeve, and a plug fixed to the top of the sleeve. The pull rod is in sealing cooperation with the sleeve. The slider is provided with a vertically arranged oil passage hole. Two parts of the inside of the sleeve above and below the oil passage hole are communicated. The upper end of the pull rod is fixedly connected to the slider, the lower end of the pull rod is connected to the lifting beam, and the plug is connected to the steel wire rope.

[0009] Further, the inner wall of the lower part of the sleeve is an inner conical surface in the large diameter direction, the lower part of the slider is an outer conical surface corresponding to the shape of the lower part of the sleeve, and the lower end of the oil passage hole is located on the outer conical surface.

[0010] Further, a guiding and positioning mechanism is further provided between the traveling crane and the lifting beam. The guiding and positioning mechanism includes a positioning frame fixedly connected to the lower part of the traveling crane, a vertically arranged guiding tube fixedly arranged on the positioning frame, and a vertically arranged column fixedly arranged on the upper part of the lifting beam. The column is located below the guiding tube, and the column and the guiding tube are coaxial.

[0011] Further, a bellmouth is fixedly arranged at the bottom of the guiding tube, and the top of the column is conical.

[0012] Further, a transverse first bolt is slidably connected to the upper surface of the positioning frame. The first bolt is located beside the guiding tube. A first jack is provided on the guiding tube at a position corresponding to the first bolt. A rotating plate is provided near the middle of the positioning frame. The middle of the rotating plate is rotatably connected to the positioning frame. A connecting rod is provided between the rotating plate and the first bolt. Two ends of the connecting rod are respectively hinged to the first bolt and the edge of the rotating plate. A first hydraulic cylinder for driving the rotating plate to rotate is further provided on the positioning frame. A second jack is provided on the upper part of the column. Driven by the winch, the column moves upward into the guiding tube. When the first jack and the second jack are aligned, the first hydraulic cylinder acts, drives the first bolt through the connecting rod, and makes the first bolt insert into the first jack and the second jack.

[0013] The positive effects of the present utility model are as follows:

[0014] 1. The utility model includes a gantry, a traveling crane, and a turnover mechanism arranged below the traveling crane for driving the turnover of bridge deck system components. After the turnover mechanism clamps the bridge deck system components, it can realize the demolding and turnover of the bridge deck system components at one time, without secondary clamping and turnover, thus improving safety and greatly increasing the turnover efficiency. Since the demolding and 180° turnover actions can be completed coherently after grasping the bridge deck system components once, it avoids damage to the bridge deck system components caused by multiple grasping and multiple upending actions. The locking mechanism includes a second hydraulic cylinder and a second bolt. The second hydraulic cylinder drives the second bolt to insert into the side of the bridge deck system components, thereby realizing reliable clamping of the bridge deck system components.

[0015] 2. A buffer mechanism is connected between the steel wire rope and the lifting beam. The buffer mechanism is provided with a slider and a sleeve. The lower part of the slider is an outer conical surface, and the inner wall of the lower part of the sleeve is an inner conical surface. When the outer conical surface of the lower part of the slider approaches the outer conical surface of the lower part of the sleeve, the distance between the outer conical surface and the inner conical surface gradually decreases, so that the resistance of the hydraulic oil flowing between the outer conical surface and the inner conical surface gradually increases, and thus the tension of the steel wire rope gradually increases, so that the gravity of the bridge deck system components and the turnover mechanism as a whole is gradually applied to the steel wire rope from small to large, reducing the tension of the steel wire rope during hoisting and extending the service life of the steel wire rope and the hoist.

DETAILED DESCRIPTION

[0027] For the convenience of description, in the following description, the direction consistent with the length direction of the track 4 is referred to as the "longitudinal direction", and the direction perpendicular to the track 4 in the horizontal plane is referred to as the "transverse direction".

[0028] Example 1

[0029] like Figures 1 to 7 As shown, a bridge deck component turning machine comprises a gantry 1, two longitudinal rails 4 parallel to each other are fixedly arranged on the top of the gantry 1, and a trolley 3 capable of longitudinally moving on the two rails 4 is arranged. The trolley drives the track wheels to rotate through a driving device, so as to longitudinally move on the rails 4. The driving device is the same as the driving device of the existing overhead crane for driving the cross beam of the overhead crane to move longitudinally, and will not be described in detail here.

[0030] A flipping mechanism 6 for driving the bridge deck component 21 to flip is provided below the traveling crane 3. The flipping mechanism 6 includes two mutually parallel horizontal lifting beams 12, a horizontal square frame arranged between the two lifting beams 12, and eight locking mechanisms 15 arranged symmetrically on both sides of the square frame for clamping the bridge deck component 21. A winch 2 is provided on the traveling crane 3. The winch 2 includes a driving motor and two drums arranged on both sides of the driving motor. Both drums are connected to the driving motor in a transmission manner. When the driving motor rotates, the two drums are driven to rotate synchronously. Two steel wire ropes 7 are wound around each drum, and there are four steel wire ropes 7 on the two drums. The four steel wire ropes 7 are respectively passed around the pulleys corresponding to the traveling crane 3 and then fixed downward at the two ends of the corresponding lifting beams 12. When the driving motor rotates, the four steel wire ropes 7 are driven to synchronously pull the two lifting beams 12 up and down.

[0031] The two lifting beams 12 are rotatably connected to the middle of one side corresponding to the square frame, respectively. The rotation axis of the square frame is longitudinal. A reduction motor 16 for driving the square frame to rotate is fixedly arranged on the lifting beam 12.

[0032] The frame includes two mutually parallel transverse first side beams 13 and two mutually parallel longitudinal second side beams 14 arranged between the two first side beams 13. The two first side beams 13 and the two second side beams 14 are fixedly connected to each other to form a rectangle. The first side beams 13 are parallel to the lifting beams 12. The middle parts of the two first side beams 13 are rotatably connected to the middle parts of the corresponding lifting beams 12 respectively. A driven gear is fixedly arranged on the outer side of one of the first side beams 13. The output shaft of the reduction motor 16 is provided with a driving gear meshing with the driven gear. When the reduction motor 16 is running, it drives the frame to rotate.

[0033] Each locking mechanism 15 includes a second hydraulic cylinder 22 vertically fixedly connected to the outer side of the corresponding second side beam 14, a sliding sleeve 23 vertically fixedly connected to the inner end of the second side beam 14, and a second latch 24 slidably connected in the sliding sleeve 23. The second latch 24 is coaxial with the push rod of the second hydraulic cylinder 22, and the outer end of the second latch 24 is fixedly connected to the second hydraulic cylinder 22 by a thread. When the second hydraulic cylinder 22 is actuated, the second latch 24 extends out or retracts into the sliding sleeve 23. After the second latch 24 extends out of the sliding sleeve 23, the second latch 24 is inserted into the corresponding hole on the side of the bridge deck component 21.

[0034] The working process of the utility model is:

[0035] 1. The crane 3 moves longitudinally, driving the turning mechanism 6 to move above the mold, and then the crane 3 stops moving.

[0036] 2. The winch 2 is operated to move the turning mechanism 6 downward, and the bridge deck component 21 to be ejected from the mold enters the frame, and the winch 2 stops operating.

[0037] 3. When the eight locking mechanisms 15 are actuated simultaneously, the corresponding eight second latches 24 are respectively inserted into the corresponding holes on the bridge deck components 21 in the frame, thereby clamping the bridge deck components 21.

[0038] 4. The winch 2 is running, pulling the four steel wire ropes 7 at the same time, driving the two lifting beams 12 to move upward synchronously, pulling the bridge deck component 21 out of the mold, achieving demoulding, and then continuing to rise. At the same time, the crane 3 moves longitudinally to keep the bridge deck component 21 away from the mold.

[0039] 5. The reduction motor 16 is running to drive the frame to flip 180 degrees, so that the bridge deck component 21 is flipped 180 degrees, and then the winch 2 is running to lower the flipped bridge deck component 21.

[0040] The utility model can realize demoulding and flipping of the bridge deck component 21 at one time after clamping the bridge deck component 21, without the need for secondary clamping and flipping, thereby improving safety and greatly improving flipping efficiency.

[0041] In addition, since the formwork removal and 180° flipping actions of the bridge deck system component 21 can be completed continuously after one grasping, damage to the bridge deck system component 21 caused by multiple graspings and multiple upending actions can be avoided.

[0042] Embodiment 2

[0043] Combined with Figure 8 and Figure 9 As shown, a buffer mechanism is connected between the lower end of the steel wire rope 7 and the lifting beam 12. The buffer mechanism includes a cylindrical sleeve 29 with a closed bottom in the vertical direction, a cylindrical slider 27 slidably connected in the sleeve 29, a pull rod 30 slidably connected through the bottom of the sleeve 29, and a plug 26 fixedly connected to the top of the sleeve 29 by threads. The pull rod 30 is hermetically fitted with the sleeve 29 through a sealing ring. A vertical oil passage hole 28 is provided on the slider 27. Two parts of the interior of the sleeve 29 above and below the oil passage hole 28 are communicated. The upper end of the pull rod 30 is fixedly connected to the slider 27, the lower end of the pull rod 30 is connected to the lifting beam 12, and the plug 26 is connected to the steel wire rope 7. A pull ring 25 is fixedly connected to the top of the plug 26 and the lower end of the pull rod 30, and the two pull rings 25 are respectively connected to the steel wire rope 7 and the lifting beam 12.

[0044] The sleeve 29 is filled with hydraulic oil. When the steel wire rope 7 rises, the plug 26 and the sleeve 29 are pulled upward, the spring 31 is compressed, and the hydraulic oil below the slider 29 flows to the upper part of the slider 29 through the oil passage hole 28. The oil passage hole 28 generates resistance, so that the overall gravity of the bridge deck system component 21 and the flipping mechanism 6 will not be suddenly applied to the steel wire rope 7, thereby prolonging the service life of the steel wire rope 7 and the hoist 2, avoiding the steel wire rope 7 from being suddenly pulled and broken (for example, if the steel wire rope 7 is directly pulled to the flipping mechanism 6, due to the inertia of the flipping mechanism 6 and the bridge deck system component 21, the pulling force on the steel wire rope 7 will be very large at the moment of lifting, and there is a risk of the steel wire rope 7 being pulled and broken after long-term use), and improving the safety during work.

[0045] The inner wall of the lower part of the sleeve 29 is an inner conical surface in the large diameter direction, the lower part of the slider 27 is an outer conical surface corresponding to the shape of the lower part of the sleeve 29, and the lower end of the oil passage hole 28 is located on the outer conical surface.

[0046] When the outer conical surface of the lower part of the slider 27 approaches the outer conical surface of the lower part of the sleeve 29, the distance between the outer conical surface and the inner conical surface gradually decreases, so that the resistance of the hydraulic oil flowing between the outer conical surface and the inner conical surface gradually increases, and then the pulling force on the steel wire rope 7 gradually increases, so that the overall gravity of the bridge deck system component 21 and the flipping mechanism 6 is gradually applied to the steel wire rope 7 from small to large, reducing the pulling force on the steel wire rope 7 during lifting.

[0047] Embodiment 3

[0048] A guiding and positioning mechanism 5 is further provided between the traveling crane 3 and the lifting beam 12. The guiding and positioning mechanism 5 includes a positioning frame 10 welded by profiles and fixedly connected to the lower part of the traveling crane 3, four vertical guiding tubes 8 fixedly arranged on the positioning frame 10, and four vertical columns 9 correspondingly fixedly arranged on the upper surfaces of the two lifting beams 12. There are two columns 9 on each lifting beam 12. The columns 9 correspond to the guiding tubes 8 one by one. The four columns 9 are respectively located below the corresponding guiding tubes 8, and the columns 9 are coaxial with the corresponding guiding tubes 8.

[0049] A horn-shaped tube 11 is fixedly arranged at the bottom of the guiding tube 8. The top of the column 9 is conical, so as to facilitate the insertion of the column 9 into the corresponding guiding tube 8.

[0050] Four transverse first pins 20 are slidably connected to the upper surface of the positioning frame 10. The four first pins 20 are respectively located beside the corresponding guiding tubes 8. A first jack is provided at a position corresponding to the first pin 20 on each guiding tube 8. Two rotating plates 18 are provided near the middle of the positioning frame 10. The two rotating plates 18 are respectively located above the corresponding lifting beams 12. The middle parts of the rotating plates 18 are rotatably connected to the positioning frame 10. Link rods 17 are provided between the rotating plates 18 and the two first pins 20 above the corresponding each lifting beam 12. The two ends of the link rod 17 are respectively hinged to the first pin 20 and the edge of the rotating plate 18. A first hydraulic cylinder 19 is provided beside each rotating plate 18 on the positioning frame 10. One end of the first hydraulic cylinder 19 is hinged to the positioning frame 10, and the other end is hinged to the edge of the corresponding rotating plate 18 near the edge.

[0051] A second jack is provided at the upper part of the column 9. Driven by the winch 2, the column 9 moves upward into the guiding tube 8. When the first jack and the second jack are aligned, the first hydraulic cylinder 19 acts, drives the first pin 20 through the link rod 17, so that the first pin 20 is inserted into the first jack and the second jack, playing a positioning role and ensuring the overall stability when the lower turning mechanism 6 works.
