Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and particularly relates to a rapid assembly and hoisting and turning platform applicable to trusses. Background Art

[0002] In long-span bridge projects, truss structures are widely used in structures such as crossbeams, towers, and piers because they can provide a large span and load-bearing capacity. The truss converts the load into axial forces (mainly tension and compression) through triangular units or grid arrangements, reduces bending stress, makes full use of the material strength, and reduces the self-weight; compared with solid web beams, the truss structure has a lighter self-weight, can reduce the load on the lower structure (such as piers and foundations), and is especially suitable for long-span bridges.

[0003] Traditional truss assembly methods mostly adopt the high-altitude loose assembly method, the cantilever assembly method, and the support assembly method. The high-altitude loose assembly method is applicable to medium and small-span steel trusses or concrete truss bridges, and uses a single-member hoisting method for connection, and only 2-3 joints can be completed per day, and the assembly connection efficiency is relatively low; the cantilever assembly method is applicable to long-span continuous truss bridges or arch bridges, and temporary stay cables or supports are required to maintain balance during assembly, so the counterweight needs to be accurately calculated, otherwise it may overturn; the support assembly method is applicable to bridges on land or in shallow water areas, and the use cost of its supports is high, and it is not applicable in deep water or soft foundation areas.

[0004] Among them, the cantilever assembly method is more widely used and less restricted by the construction environment. However, when using the cantilever assembly method, due to the large span and heavy weight of the truss, the turning operation of the truss is difficult. If the operation is improper, it is very easy to cause safety accidents and may also damage the structural integrity of the truss; at the same time, the existing hoisting equipment and platforms are difficult to meet the dual requirements of rapid truss assembly and precise hoisting and turning at the same time, which limits the overall construction progress and quality. Summary of the Invention

[0005] Aiming at the deficiencies in the prior art, the present invention provides a rapid assembly and hoisting and turning platform applicable to trusses to solve the problem that the existing hoisting equipment and platforms are difficult to meet the dual requirements of rapid truss assembly and precise hoisting and turning at the same time, which limits the overall construction progress and quality.

[0006] To achieve the above object, the basic solution of the present invention is as follows: A rapid assembly and hoisting and turning platform applicable to trusses includes an assembly support turning unit and a hoisting and installation unit that cooperates with the assembly support turning unit. The hoisting and installation unit is connected to one side of the truss. The assembly support turning unit includes:

[0007] A support frame, which is horizontally and fixedly installed on the ground;

[0008] A plurality of slide rails are fixedly installed on the support frame, and the axis of the slide rail is perpendicular to the straight line formed by the two ends of the truss to be installed.

[0009] A plurality of pulling components are connected to the side of the truss away from the hoisting and installation unit, and the side of the truss close to the pulling component is in sliding contact with the slide rail.

[0010] The technical principle of the present invention is as follows: Before hoisting the truss, first transport the truss members to the construction site, and sequentially weld and assemble the truss members on the support frame and the slide rail to realize the pre-installation of the truss; the support frame and the slide rail can quickly and accurately position the truss members, facilitating the assembly operation.

[0011] After the pre-installation of the truss is completed, the hoisting and installation unit is fixed to the upper chord of the truss, and the pulling component is fixed to the lower chord; the hoisting and installation unit and the pulling component synchronously pull the truss, synchronously realizing the flipping of the truss; when the upper side of the truss moves upward under the traction of the hoisting and installation unit, the lower side of the truss synchronously moves along the slide rail. At this time, the pulling component also pulls the lower side of the truss, so that the lower side of the truss stably moves horizontally along the slide rail. The slide rail and the support frame can stably support the flipping of the truss; when the truss is hoisted, both sides are simultaneously and cooperatively pulled, so that the flipping of the truss is stable and not prone to horizontal shaking when the truss is hoisted and separated from the slide rail, effectively reducing the probability of safety accidents and avoiding damage to the truss structure at the same time; realizing the precise hoisting of the truss, and also facilitating the accurate movement of the truss to the welding and assembly place, improving the installation efficiency of the entire truss structure.

[0012] Further, the pulling component includes:

[0013] A winch is fixedly installed on the ground or the support frame;

[0014] A turning pulley is rotatably installed on the support frame or the ground, and the axis of rotation of the turning pulley is perpendicular to the axis of the slide rail;

[0015] A steel wire rope, one end of the steel wire rope is connected to the winch, and the steel wire rope is wound around the turning pulley and detachably connected to the side of the truss away from the hoisting and installation unit.

[0016] Through the above settings, the winch applies force to the truss through the steel wire rope, and the turning pulley can provide stable support for the horizontal traction of the steel wire rope and a stable force application angle in the horizontal direction, facilitating the control of the lower chord of the truss to stably move horizontally along the slide rail and improving the stability of the truss flipping.

[0017] Further, it further includes a terminal limit unit, and the terminal limit unit includes:

[0018] A sliding steel plate coated with lubricating oil is horizontally fixedly installed on the end of the slide rail, and the vertical plane where the sliding steel plate is located is perpendicular to the axes of the plurality of slide rails;

[0019] A limit baffle is vertically fixedly installed on the upper surface of the sliding steel plate, and the limit baffle can be against the truss.

[0020] Through the above arrangement, when the lower chord of the truss moves to the sliding steel plate, it means that the flipping of the truss is about to be completed and the truss is about to leave the slide rail. At this time, the lubricated sliding steel plate can allow the truss to slide to the end of the slide rail more quickly and then separate from the slide rail; at the same time, part of the truss can be against the limit baffle, thereby limiting the movement of the lower side of the truss, and the limit baffle can vertically guide the truss after hoisting to prevent the truss from swinging in the horizontal direction after hoisting.

[0021] Furthermore, the winch is located on one side of the support frame, the flip pulley is located on the other side of the support frame, and the flip pulley is located outside the range of the support frame.

[0022] Through the above arrangement, the output angle of the traction force can be more stably controlled by limiting the position of the flip pulley, and during the process of winding the wire rope, the flip pulley can support the traction of the wire rope, and the traction force output of the winch is more stable.

[0023] Furthermore, the hoisting installation unit is a tower crane or a truck crane.

[0024] Through the above arrangement, the tower crane or the truck crane can provide stable traction for the hoisting of the truss.

[0025] Furthermore, it also includes a plurality of binding and limiting units, and the binding and limiting units include:

[0026] first hoop plate;

[0027] A second hoop plate, the second hoop plate and the first hoop plate form a hoop; the outer walls of the first hoop plate and the second hoop plate are both provided with an incomplete annular slide groove, a connecting component is tightly and slidably installed in the slide groove, and the connecting component is connected to an end of the wire rope or the hoisting installation unit close to the truss;

[0028] a first wing plate fixed to an end of the first hoop plate;

[0029] The second wing plate is fixed on the end of the second hoop plate, the second wing plate is detachably connected to the first wing plate, and one end of the first hoop plate away from the first wing plate is hinged to one end of the second hoop plate away from the second wing plate.

[0030] With the above settings, the connecting component can cooperate with the wire rope or the hoisting and installation unit, so that the wire rope or the hoisting and installation unit can stably apply the traction force to the first hoop plate and the second hoop plate; when hoisting the truss, the angle of the truss changes after flipping under the traction, and at this time, the force application angles of the wire rope and the steel strand also change relative to the truss. The connecting component can cooperate with the sliding grooves on the first hoop plate and the second hoop plate, so that the connecting component rotates circumferentially relative to the first hoop plate and the second hoop plate along the sliding grooves, and can synchronously and stably change the force application angle, and can stably transfer the traction force to the first hoop plate and the second hoop plate.

[0031] Furthermore, first flanges and second flanges are fixedly arranged on the outer walls of the first hoop plate and the second hoop plate respectively. The first flanges and the second flanges are both in an incomplete ring shape, and the first flanges and the second flanges are arranged oppositely and coaxially with the second hoop plate or the first hoop plate; the sliding grooves are arranged between the first flanges and the second flanges, and the sliding grooves are also in an incomplete ring shape arranged along the contour direction of the first flanges. The connecting component is in sliding contact with the inner walls of the sliding grooves of the first flanges and the second flanges and can be abutted.

[0032] With the above settings, the first flanges and the second flanges can reinforce the first hoop plate and the second hoop plate, and it is convenient to arrange the sliding grooves between the first flanges and the second flanges. The first flanges and the second flanges can provide stable support for the connecting component.

[0033] Furthermore, the binding and limiting unit further includes:

[0034] A plurality of tightening bolts, the ends of the tightening bolts penetrate along the radial direction of the first hoop plate or the second hoop plate and are threadedly connected with the first hoop plate or the second hoop plate;

[0035] A plurality of anti-slip sheets that can be attached to the truss members, and the anti-slip sheets are fixedly connected to one end of the tightening bolts located inside the first hoop plate or the second hoop plate.

[0036] With the above settings, if there is still a gap between the inner walls of the first hoop plate and the second hoop plate and the outer walls of the upper chord or the lower chord after the first hoop plate and the second hoop plate are installed on the upper chord or the lower chord, then screw the tightening bolts on the first hoop plate or the second hoop plate. The tightening bolts push the anti-slip sheets to move towards the upper chord or the lower chord, so that the anti-slip sheets are tightly abutted and installed on the upper chord or the lower chord, which can make the binding and limiting unit adapt to the fixed installation of the upper chord or the lower chord with different diameter specifications, and at the same time can make the binding and limiting unit more stably bound to the upper chord or the lower chord; at the same time, the tightening bolts and the anti-slip sheets stably abut the upper chord or the lower chord, reducing the probability of the entire truss slipping and toppling in the horizontal direction.

[0037] Furthermore, a plurality of tightening bolts are uniformly arranged circumferentially around the first hoop plate and the second hoop plate.

[0038] With the above settings, several fastening bolts can apply a more uniform fastening force to the outer wall of the upper chord or the lower chord, making the binding and limiting unit more stably installed on the upper chord or the lower chord.

[0039] Furthermore, several fastening bolts are located at the side of the first hoop plate or the first flange of the second hoop plate away from the second flange and on the side of the second flange away from the first flange.

[0040] With the above settings, fastening bolts are installed on both sides of the first hoop plate or the second hoop plate, which can make the fastening force on the upper chord or the lower chord more stable, and the overall truss is less likely to slip in the horizontal direction.

Detailed implementation manners

[0049] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0050] Embodiment 1

[0051] This embodiment is basically as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown. An embodiment of the present invention provides a rapid assembly and hoisting and turning platform applicable to a truss, including an assembly support turning unit, a terminal limit unit, and a hoisting and installation unit cooperating with the assembly support turning unit. The hoisting and installation unit is detachably connected to the hoisting point one 801 and the hoisting point two 802 of the truss 80. As Figure 1 and 4 shown, the hoisting and installation unit is the tower crane 10.

[0052] As Figure 2 , Figure 3 and Figure 4 shown, the assembly support turning unit includes a support frame 20, two groups of slide rails 202, and two groups of pulling components. The support frame 20 is rectangular, and the support frame 20 is horizontally laid and welded by I25 steel beams. Six support bases 201 are installed on the lower side of the support frame 20, and the six support bases 201 are evenly distributed on the lower side of the support frame 20. The support bases 201 are connected to the concrete ground through high-strength steel bars; As Figure 3 and Figure 5 shown, the slide rail 202 is horizontally laid by an I56 steel beam, and the two slide rails 202 are welded to the left and right sides of the support frame 20. The axis of the slide rail 202 is perpendicular to the straight line formed by the two ends of the truss 80 to be installed.

[0053] At the same time, as Figures 1 - 3As shown, the pulling assembly includes two groups of winches 30, two groups of turning pulleys 301 and two groups of steel wire ropes 302. The winches 30, turning pulleys 301 and steel wire ropes 302 are grouped in one-to-one correspondence. The winches 30 are located on the upper side of the support frame 20, and the turning pulleys 301 are located on the lower side of the support frame 20 and outside the range of the support frame 20. The winches 30 are fixedly installed on the support frame 20 through fastening bolts 601. The turning pulleys 301 are rotatably installed on the support frame 20, and the rotation axis of the turning pulleys 301 is perpendicular to the axis of the slide rail 202. One end of the steel wire rope 302 is connected to the winch 30. The steel wire rope 302 is wound around the turning pulley 301 and is detachably connected to the lifting points three 803 and four 804 of the truss 80.

[0054] As Figure 4 and Figure 5 shown, the terminal limit unit includes a sliding steel plate 401 coated with lubricating oil and a limit baffle 402. The sliding steel plate 401 is horizontally welded to the right end of the slide rail 202, and the vertical plane where the sliding steel plate 401 is located is perpendicular to the axes of the two slide rails 202. The limit baffle 402 is vertically welded to the upper surface of the sliding steel plate 401, and the limit baffle 402 can abut against the truss 80.

[0055] When the quick assembly and hoisting and turning platform applicable to the truss in this embodiment is in use, first transport the truss members to the construction site, and sequentially weld and assemble the truss members on the support frame 20 and the slide rail 202. There are multiple positioning marks on the support frame 20, which can quickly and accurately position the truss members, facilitating the assembly operation, and finally form the truss 80 as shown in Figure 1 、 2 and 4, realizing the pre-installation of the truss 80. During the pre-installation process, the assembly efficiency of the truss 80 can be significantly improved. Compared with the traditional assembly method, the assembly time can be shortened by more than 20%, and the required time for truss installation can also be finally shortened.

[0056] Then hoist and transfer the pre-installed truss 80 to the truss 80 installation position. Before hoisting the truss 80, first pass the end of the steel wire rope 302 around the turning pulley 301 and fix it to the lifting points three 803 and four 804 of the truss 80. The steel strand 101 of the tower crane 10 is fixed to the lifting points one 801 and two 802 of the truss 80 to complete the preparation for hoisting the truss 80.

[0057] When hoisting, the steel strand 101 of the tower crane 10 is first pre-tightened, so that as Figure 1The lower side of the truss 80 shown in the figure first detaches from the support frame 20 and the slide rail 202; at the same time, the winch 30 cooperates with the tower crane 10, and the winch 30 also synchronously tightens the wire rope 302, so that the end of the wire rope 302 pulls the lifting point three 803 and the lifting point four 804 of the truss 80 to move in the direction close to the lower end of the slide rail 202; in this process, the winch 30 and the tower crane 10 cooperate to enable the assembled truss 80 to be stably flipped to a vertical state. When the truss 80 is flipped, the upper side of the truss 80 is pulled by the winch 30 and the tower crane 10. The lower edge slides on the slide rail 202, and the slide rail 202 provides stable support for the horizontal movement of the upper side of the truss 80; when the upper side of the truss 80 moves to the lower end of the slide rail 202, the lower side of the truss 80 contacts the sliding steel plate 401, so that the truss 80 can be smoothly separated from the slide rail 202 under the action of lifting; at the same time, part of the truss 80 can be against the limit baffle 402, thereby limiting the movement of the lower side of the truss 80, and the limit baffle 402 can vertically guide the truss 80 after lifting to prevent the truss 80 from swinging in the horizontal direction after lifting.

[0058] When the truss 80 is separated from the slide rail 202 and the support frame 20, the steel wire rope 302 fixed on the lower chord of the truss 80 is released, and the turning operation of the truss 80 is now completed.

[0059] In the above process, the tower crane 10 and the winch 30 work together, and the forces of the two need to be finely adjusted according to the structural characteristics and weight distribution of the truss 80 to maintain the mechanical balance of the overall structure; and with the precise matching of the forces of the two, the sliding tendency that may be caused by the lifting process can be effectively offset, ensuring that the truss 80 always maintains on the predetermined motion trajectory in the initial stage of turning over, making the turning of the truss 80 more stable, which can effectively reduce the probability of safety accidents and avoid damage to the truss 80 structure; at the same time, the overall construction period is shortened, the construction cost is reduced, and the economic benefits of the project are improved.

[0060] Example 2

[0061] The difference between Example 2 and Example 1 is basically as shown in the attached Figure 6 and Figure 7 As shown, it also includes four binding limit units, which correspond to the lifting point one 801, lifting point two 802, lifting point three 803 and lifting point four 804 of the truss 80 respectively. The binding limit units at the lifting point one 801 and the lifting point two 802 are connected to the steel strand 101 of the tower crane 10; the binding limit units at the lifting point three 803 and the lifting point four 804 are connected to the steel wire rope 302.

[0062] As attached Figure 6 and Figure 7As shown, the binding and limiting unit includes a first hoop plate 501, a second hoop plate 502, a first wing plate 503 integrally formed at the end of the first hoop plate 501, a second wing plate 504 integrally formed at the end of the second hoop plate 502, a number of tightening bolts 601, and a number of anti-slip sheets 602 that can be attached to the truss member. The second hoop plate 502 and the first hoop plate 501 form a hug hoop; the second wing plate 504 and the first wing plate 503 are detachably connected by a locking bolt 505 and a nut. One end of the first hoop plate 501 away from the first wing plate 503 and one end of the second hoop plate 502 away from the second wing plate 504 are hinged by a hinge; at the same time, as Figure 6 shown, incomplete annular chutes 703 are provided on the outer walls of the first hoop plate 501 and the second hoop plate 502. First flanges 701 and second flanges 702 are integrally formed on the outer walls of the first hoop plate 501 and the second hoop plate 502. The first flanges 701 and the second flanges 702 are both in an incomplete annular shape, and the first flanges 701 and the second flanges 702 are arranged oppositely and coaxially with the second hoop plate 502 or the first hoop plate 501; the chutes 703 are provided between the first flanges 701 and the second flanges 702, and the chutes 703 are also in an incomplete annular shape arranged along the contour direction of the first flanges 701.

[0063] As Figure 6 shown, a connection component is tightly abutted and slidably installed in the chute 703. The connection component includes a connection slide rod 705, a connection key 706, and a limit slide member 708. The connection slide rod 705 is slidably installed in the chute 703 supported by the first flange 701 and the second flange 702. The connection key 706 is fixedly connected to the connection slide rod 705; the limit slide member 708 is slidably installed between the side walls of the first flange 701 and the second flange 702. The sides of the first flange 701 and the second flange 702 close to the limit slide member 708 are both arc surfaces 704 that fit the end surface of the limit slide member 708. The minimum gap between the first flange 701 and the second flange 702 is smaller than the diameter of the connection slide rod 705; a through groove 707 for fixedly connecting with the steel wire rope 302 or the steel strand 101 is provided through the connection key 706.

[0064] At the same time, as Figure 6 and 7 shown, the end of the tightening bolt 601 penetrates radially along the first hoop plate 501 or the second hoop plate 502 and is threadedly connected to the first hoop plate 501 or the second hoop plate 502; the anti-slip sheet 602 is a rubber sheet, and the anti-slip sheet 602 is fixedly connected to one end of the tightening bolt 601 located inside the first hoop plate 501 or the second hoop plate 502; at the same time, a number of tightening bolts 601 are evenly arranged around the circumferences of the first hoop plate 501 and the second hoop plate 502, and a number of tightening bolts 601 are located on the side of the first flange 701 of the first hoop plate 501 or the second hoop plate 502 away from the second flange 702 and on the side of the second flange 702 away from the first flange 701.

[0065] When the quick assembly and hoisting and turning platform applicable to the truss in this embodiment is in use, after the pre-installation of the truss 80 is completed, the four binding and limiting units are respectively installed at the lifting points 801, 802, 803 and 804 of the truss 80.

[0066] When installing a single binding and limiting unit, first loosen the locking bolts 505 and nuts at the first wing plate 503 and the second wing plate 504, so that the first hoop plate 501 and the second hoop plate 502 are opened around the hinge, and then wrap the first hoop plate 501 and the second hoop plate 502 around the upper chord or the lower chord of the truss 80, and then install the locking bolts 505 and nuts to lock the first wing plate 503 and the second wing plate 504; at this time, if there is still a gap between the inner wall of the first hoop plate 501 and the second hoop plate 502 and the outer wall of the upper chord or the lower chord, then turn the tightening bolt 601 on the first hoop plate 501 or the second hoop plate 502, and the tightening bolt 601 pushes the anti-slip piece 602 to move towards the upper chord or the lower chord, so that the anti-slip piece 602 is tightly pressed on the upper chord or the lower chord; through the cooperation of the tightening bolt 601, the first wing plate 503 and the second wing plate 504, the binding and limiting unit can adapt to the fixed installation of the upper chord or the lower chord with different diameter specifications, and at the same time, the binding and limiting unit can be more stably bound to the upper chord or the lower chord.

[0067] Before hoisting the truss 80, the steel wire rope 302 or the steel strand 101 can be respectively installed at the through groove 707 of the connection key 706 of the first wing plate 503 or the second wing plate 504, or can be installed at the through grooves 707 of the two connection keys 706 in a single binding and limiting unit at the same time. The appropriate installation method can be judged according to the turning angle and the connection strength of the truss 80 during the turning process, and the connection of the two connection keys 706 or the connection key 706 on one side can be flexibly selected.

[0068] When hoisting the truss 80, the angle of the truss 80 changes after turning under the traction action. At this time, the force application angles of the steel wire rope 302 and the steel strand 101 also change relative to the truss 80. The steel wire rope 302 or the steel strand 101 can drive the connection slide bar 705, the connection key 706 and the limit slide part 708 to move in the chute 703 relative to the first flange 701 and the second flange 702, and can synchronously and stably change the force application angle, and can stably transmit the traction force to the first hoop plate 501 and the second hoop plate 502; at the same time, the tightening bolt 601 and the anti-slip piece 602 tightly press the upper chord or the lower chord, reducing the probability of the whole truss 80 slipping and tipping in the horizontal direction, making the turning and hoisting of the truss 80 more stable, and also enabling the truss 80 to be more accurately hoisted to the welding and installation position, improving the overall installation efficiency of the truss 80.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
