Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction equipment, and in particular relates to a hydraulic self-propelled anti-collision wall formwork trolley. Background Art

[0002] With the rapid development of my country's infrastructure, the requirements for road and bridge construction are getting higher and higher. The construction of bridges should consider its applicability, economy, safety, and ensure its construction efficiency and beautiful appearance. The crash barriers on both sides of the bridge are a kind of safety protection measures for bridges. With their unique structural form that bends in the direction of driving and the texture of reinforced concrete, they play an important role in buffering the impact of vehicles, ensuring traffic safety, and protecting people's lives and property. As a safety facility, the crash barrier of the bridge is also the most important part of the bridge image project. It requires both internal quality and appearance quality to be a fine product. The crash barrier is to ensure construction efficiency and beautiful appearance. When pouring concrete for the crash barrier, the requirements are relatively high. At present, small templates are used more in construction. Because the smaller the template, the more joints, the more uneven the surface of the joints and the easier it is to leak slurry, when the small template is erected, more reinforcement points and tie rod points are needed to fix the overall template. The construction of small templates requires each piece to be moved separately, and then connected and positioned for reinforcement, which requires more labor and resources. Summary of the invention

[0003] In view of the above problems, the present invention provides a hydraulic self-propelled anti-collision wall formwork trolley, which can reduce the investment in construction personnel and auxiliary equipment, improve construction efficiency, reduce cost investment, ensure construction quality, and improve the aesthetics of the anti-collision wall.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A hydraulic self-propelled anti-collision wall formwork trolley comprises a gantry with walking wheels on the bottom of both sides, and telescopic beams are symmetrically arranged on both sides of the gantry; a transverse cylinder for controlling the extension and retraction of the telescopic beam is arranged on the gantry; the lower end of the telescopic beam is connected to an ear seat through a lifting cylinder; an outer formwork and an inner formwork are hinged at the lower end of the ear seat, and the outer formwork and the inner formwork together constitute the formed body required for the anti-collision wall concrete; a drooping hanger is arranged at the end of the telescopic beam, and a hanging basket for staff operation is arranged at the lower end of the hanger; a second positioning and demoulding cylinder is arranged between the outer formwork and the hanger; a first positioning and demoulding cylinder is arranged between the inner formwork and the gantry.

[0006] As a further improvement of the above technical solution:

[0007] The gantry is formed into an inverted U shape by a horizontal beam at the top and vertical beams at both ends; the lower end of the vertical beam is connected to the walking wheel through a lifting cylinder.

[0008] A first demoulding positioning support is arranged between the upper end of the inner template and the door frame, and a second demoulding positioning support is arranged between the lower end and the door frame.

[0009] A movable pull rod is provided between the outer template and the inner template to penetrate and fix the two.

[0010] The outer formwork and the inner formwork are both integral steel formworks.

[0011] The ear seat is an inverted U-shaped structure; a cavity for placing the railing is formed inside; horizontally movable clamp blocks are symmetrically arranged on both sides of the ear seat; a toothed plate inclined to the horizontal plane and extending into the inner cavity of the ear seat is arranged at the lower end of the clamp block; the racks and tooth grooves of the toothed plates of the two clamp blocks cross-coordinate with each other to jointly support the railing.

[0012] Synchronous oil cylinders are symmetrically arranged at both ends of the top surface of the ear seat; and the telescopic shafts of the synchronous oil cylinders are respectively connected to the corresponding fixture blocks.

[0013] A positioning hole is arranged at the upper end of the ear seat; a horizontal positioning shaft is arranged at the inner side of the fixture block; and the positioning shaft is movably inserted into the positioning hole.

[0014] A vertical downward pressure oil cylinder is arranged at the top of the inner cavity of the ear seat.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. This vehicle can realize the rapid construction of crash barriers on both sides of the bridge simultaneously. Since the hoisting, positioning and demoulding of the crash wall formwork can be controlled by the lifting cylinder and demoulding positioning cylinder of the equipment, it can reduce the investment of more construction personnel and auxiliary equipment, reduce construction costs, and improve construction efficiency and quality.

[0017] 2. Since the positioning and demoulding of the template is mechanically controlled on this vehicle, the template can adopt an integral steel template to ensure the surface flatness and accurate forming of the anti-collision wall.

[0018] 3. The anti-collision wall template in this vehicle can not only move horizontally through automatic control of the equipment, but also move vertically. Therefore, the positioning of the template is more flexible and can adapt to the requirements of wall positions of different widths and heights.

[0019] 4. The overall structure of this trolley is a gantry structure, and a hanging basket is set on the outside of the template, so that the staff can easily check and adjust the construction status of the outer template, making the operation more convenient.

[0020] 5. A special fixture for controlling the positioning construction of the railing is set in the ear seat of this vehicle, which can realize the simultaneous installation of the railing during the construction of the anti-collision wall. At the same time, it eliminates a series of processes such as secondary hoisting, drilling, installation, and transportation required for the later installation of the railing, and completes the installation of the supporting equipment of the anti-collision wall at one time, which greatly shortens the construction time of the anti-collision wall and speeds up the investment of the anti-collision wall.

[0021] 6. The clamp block used in the ear seat of this vehicle can not only store and position the anti-collision wall railing, but also realize the automatic installation of the railing, ensure the accuracy of the installation position of the railing, eliminate the need for subsequent drilling installation, and make the installation more firm and reliable.

[0037] A hydraulic self-propelled crash barrier formwork trolley comprises a gantry 3 with walking wheels 8 at the bottom of both sides, telescopic beams 6 are symmetrically arranged on both sides of the gantry 3; a transverse cylinder 7 for controlling the extension and retraction of the telescopic beam 6 is arranged on the gantry 3; the lower end of the telescopic beam 6 is connected to an ear seat 18 through a lifting cylinder 12; an outer template 131 and an inner template 132 are hinged at the lower end of the ear seat 18, and the outer template 131 and the inner template 132 together constitute the molded body required for the concrete of the crash barrier 2; a drooping hanger 10 is arranged at the end of the telescopic beam 6, and a hanging basket 11 for staff operation is arranged at the lower end of the hanger 10; a second positioning and demoulding cylinder 17 is arranged between the outer template 131 and the hanger 10; a first positioning and demoulding cylinder 15 is arranged between the inner template 132 and the gantry 3.

[0038] Further optimization based on the above embodiment:

[0039] Specifically, Figure 2 As shown, the gantry 3 is composed of a cross beam 4 at the top and vertical beams 5 at both ends to form an inverted U shape; the lower end of the vertical beam 5 is connected to the travel wheel 8 through a lifting cylinder 9. The gantry 3 and the cross beam 4 are connected to each other through reinforcing ribs to improve the connection firmness; the upper end of the travel wheel 8 can be telescopically inserted into the lower end of the vertical beam 5; one end of the lifting cylinder 9 is connected to the vertical beam 5, and the other end is connected to the travel wheel 8; the travel wheel 8 includes a roller and a corresponding drive motor.

[0040] Specifically, Figure 3As shown, in order to improve the fixing stability of the template to the anti-collision wall, a first demoulding positioning support 14 is provided between the upper end of the inner template 132 and the door frame 3, and a second demoulding positioning support 16 is provided between the lower end and the door frame 3. The support member adopts a screw and a screw sleeve structure, and the length can be adjusted.

[0041] Specifically, Figure 4 As shown, in order to further improve the casting and forming stability of the template for the crash wall, a movable tie rod 19 is provided between the outer template 131 and the inner template 132 to fix the two.

[0042] Specifically, in order to improve the forming effect of the anti-collision wall, the outer template 131 and the inner template 132 are both integral steel templates.

[0043] Specifically, Figure 9-10 As shown, in order to enable the anti-collision wall and the railing at its upper end to be formed and installed together at one time, the ear seat 18 is an inverted U-shaped structure; a cavity for placing the railing 24 is formed inside; horizontally movable clamp blocks 21 are symmetrically arranged on both sides of the ear seat 18; a toothed plate 23 inclined to the horizontal plane and extending into the inner cavity of the ear seat 18 is arranged at the lower end of the clamp block 21; the racks and tooth grooves of the toothed plates 23 of the two clamp blocks 21 cross-match with each other to jointly support the railing 24.

[0044] Specifically, Fig. 9 As shown, synchronous cylinders 20 are symmetrically arranged at both ends of the top surface of the ear seat 18; the telescopic shafts of the synchronous cylinders 20 are respectively connected to the corresponding clamp blocks 21. The two synchronous cylinders 20 are synchronously extended and retracted. When the synchronous cylinders 20 are synchronously shortened, the clamp blocks 21 are brought closer to each other, so that the two toothed plates 23 cross each other to hold the railing upward to prevent it from falling; when the synchronous cylinders 20 are synchronously extended, the two clamp blocks 21 are moved away from each other, so that the two toothed plates 23 cross each other and open, so that the railing falls slowly, so that the support seat of the railing is inserted into the unsolidified concrete anti-collision wall. When the support seat is inserted to an appropriate depth, the synchronous cylinder 20 stops moving. After the concrete is completely solidified, the synchronous cylinder 20 controls the clamp block 21 to open completely.

[0045] Specifically, Fig. 9 As shown, in order to improve the stability of the clamp block 21, a positioning hole is provided at the upper end of the ear seat 18; a horizontal positioning shaft 22 is provided inside the clamp block 21; and the positioning shaft 22 is movably inserted into the positioning hole.

[0046] Specifically, Fig.12 As shown, in order to allow the railing to be smoothly inserted into the concrete and to prevent the railing from being unable to be inserted due to the concrete being too hard, a vertical downward pressure cylinder 25 is provided at the top of the inner cavity of the ear seat 18.

[0047] The overall structural principle of the present invention:

[0048] A hydraulic self-propelled crash wall formwork trolley is provided, which adopts symmetrical arrangement on both sides, integral pouring construction and integral forward movement construction. It mainly consists of a crash wall formwork, including an outer formwork and an inner formwork, a hanging basket 11, a door frame 3, a walking wheel 8, a telescopic beam, a lifting cylinder, and a demoulding positioning support.

[0049] 1. The outer formwork and the inner formwork constitute the forming body required for the anti-collision wall concrete. The outer formwork and the inner formwork are integral steel formworks, and a movable tie rod is set between the outer formwork and the inner formwork to fix the positions of the two. There is a positioning demoulding cylinder between the outer formwork and the hanging basket. There is a positioning demoulding cylinder between the inner formwork and the door frame. The outer formwork and the inner formwork are connected to the lifting cylinder through the ear seat.

[0050] 2. The hanging basket is used for the construction platform of the outer template of the anti-collision wall and the positioning and reinforcement of the template. The hanging basket is located below one end of the transverse moving component.

[0051] 3. The gantry is an integral frame, with telescopic beams connected to the left and right sides, and the travel wheels that move forward and backward are located below the gantry. An oil cylinder for adjusting the position up and down is set between the travel wheels and the gantry. The travel wheels can be located below the gantry and can carry the entire trolley to move.

[0052] 4. There is a hanging basket and an outer template carried by a lifting cylinder under the telescopic beam. The telescopic beam can be extended to carry the hanging basket and the template to adjust the horizontal position.

[0053] 5. The lifting cylinder is a telescopic beam that is a movable connecting part between the templates, which is convenient for overall positioning adjustment and template demoulding.

[0054] 6. When demolding, the templates will move outwards separately, and then be lifted upward as a whole by the lifting cylinder, so that the templates are separated from the concrete.

[0055] The operation of the present invention:

[0056] The walking wheel 8 drives the portal frame 3 to move on the bridge. When it moves to the predetermined position, the first positioning demoulding cylinder 15 and the second positioning demoulding cylinder 17 respectively control the outer template 131 and the inner template 132 to close together to form the molded body required for the anti-collision wall concrete. At the same time, the staff can adjust the second demoulding positioning support 16 and the first demoulding positioning support 14 between the inner template and the portal frame to improve the positioning firmness of the template. At the same time, the movable pull rod 19 can be installed between the outer template and the inner template to further improve the molding effect. The staff drives the equipment to pour concrete into the template molding bodies on both sides of the portal frame 3, and the concrete solidifies in the molding bodies to form anti-collision walls; when the anti-collision wall is formed stably, the movable pull rod 19 and the demoulding positioning support are removed, and the equipment drives the positioning demoulding cylinder to retract, and the templates are each released to the outside, and then lifted upward as a whole by the lifting cylinder, so that the templates are separated from the concrete. The walking wheel 8 drives the equipment to move to the next construction point for construction.

[0057] When it is necessary to install the railing 24 on the crash barrier at one time, the staff will put the railing 24 into the U-shaped inner cavity of the ear seat 18 in advance, drive the synchronous cylinder 20 to retract, and clamp the railing 24 in the ear seat 18. According to the above-mentioned crash barrier construction steps, the construction is carried out. After the crash barrier is poured, the synchronous cylinder 20 extends, and the toothed plate 23 of the clamp block 21 slowly moves outward, so that the railing 24 slowly falls, and finally the support seat at the lower end of the railing 24 is immersed in the concrete. After the concrete solidifies, the demoulding operation can be started. In order to prevent the railing 24 from being unable to be immersed in the concrete due to its small mass, the downward pressure cylinder 25 can be started, and the downward pressure cylinder 25 applies downward pressure to the railing 24, thereby ensuring that the support seat of the railing 24 and the concrete of the crash barrier are immersed in the installation.
