Description

Technical Field

[0001] This utility model relates to the field of concrete pouring construction technology, specifically to a segmented adjustable steel formwork trolley. Background Technology

[0002] Formwork trolleys are specialized mechanical construction equipment used in tunnel construction to cast concrete slabs for tunnel lining, depending on the tunnel's internal shape and the method of concrete pouring. They are widely used in railway, highway, and water conservancy and hydropower engineering projects. Using formwork trolleys not only avoids construction interference and improves construction efficiency, but more importantly, it greatly improves the quality of tunnel lining construction and also enhances the mechanization of tunnel construction.

[0003] In the construction of box culverts and underground channels, in order to ensure the construction quality, cast-in-place concrete is used. The construction includes a concrete base slab, concrete side walls, and a concrete top slab. During the pouring process, a "U"-shaped concrete base slab is poured first. After the concrete base slab is qualified, the concrete side walls and concrete top slab are poured in one piece. Spacing is left between multiple sets of concrete side walls to form the underground channel. During the pouring of concrete side walls and concrete top slab, scaffolding is usually erected in the underground channel for support. Then, formwork is installed on the top and sides of the scaffolding to form the concrete pouring support formwork. The installation and dismantling of scaffolding and formwork is a large-scale project, which takes a long time, has low construction efficiency, and high construction costs.

[0004] Utility model patent CN217107044U discloses a tunnel construction structure on a steel formwork trolley with a centrally located ventilation duct. The structure includes an arc-shaped top plate; a steel formwork trolley that supports and lifts the arc-shaped top plate; a support plate located at the bottom of the steel formwork trolley to provide a load-bearing foundation, with the bottom of the arc-shaped top plate in contact with the inner surface of the tunnel floor; and a ventilation duct installed in the middle of the steel formwork trolley, creating a workspace at the bottom of the trolley. Because the steel formwork trolley supports the arc-shaped top plate under the support plate, and the ventilation duct is installed in the middle of the trolley, creating a workspace at the bottom of the trolley, the problem of inconvenient workspace at the bottom of the steel formwork trolley is solved, improving construction efficiency. However, in this patent, after the external concrete quality is satisfactory and the steel formwork trolley is removed, it is difficult to adjust the trolley to the designated position when moving to the next work station. Adjusting the position of the steel formwork trolley is time-consuming and inefficient. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] In one embodiment, see Figure 1 The present invention relates to a segmented adjustable steel mold trolley, comprising a trolley body assembly and a support assembly.

[0020] The vehicle body assembly includes a frame 1 and a movable component 2 movably mounted on the frame 1. A steering component 3 is provided between the frame 1 and the movable component 2. The steering component 3 engages with the movable component 2. Under the action of an external force, the steering component 3 moves axially, thereby causing the movable component 2 to rotate circumferentially, so as to adjust the movement direction of the movable component 2 to be perpendicular or parallel to the axial direction of the steering component 3. The support assembly includes side support plates 4 movably mounted on both sides of the frame 1 and a top support plate 5 movably mounted on the frame 1. A first guide member 6 is slidably provided between the side support plates 4 and the frame 1. A side pusher 7 is provided between the side support plate 4 and the frame 1. A first limiter 8 is provided on the first guide 6. The side pusher 7 moves back and forth in a straight line under the action of external force, so that the side support plate 4 moves back and forth in a straight line. A second guide 9 is slidably provided between the top support plate 5 and the frame 1. A top pusher 10 is provided between the top support plate 5 and the frame 1. A second limiter 11 is provided on the second guide 9. The top pusher 10 moves back and forth in a straight line under the action of external force, so that the top support plate 5 moves up to engage with the side support plate 4 or moves down to separate from the side support plate 4.

[0021] In the construction of box culverts, the culverts have a square structure, such as... Figure 3 As shown, after the concrete base slab 12 is poured, the concrete side walls 13 and the concrete top slab 14 that make up the culvert are poured as a whole, and a waterstop strip 15 is set between the concrete side walls 13 and the concrete base slab 12. In this embodiment, two sets of side support plates 4 are set to support the two side walls in the same culvert channel, and the top support plate 5 is used to support the concrete top slab 14 that makes up the culvert.

[0022] Preferably, the frame 1 includes four sets of vertical rods 101 and eight sets of horizontal rods 102. The eight sets of horizontal rods 102 and the four sets of vertical rods 101 are connected end to end to form a rectangular frame structure, which provides support for the entire steel mold trolley. The vertical rods 101 and the horizontal rods 102 can be connected by welding or bolts.

[0023] Preferably, the bottom end of the vertical bar 101 extends beyond the horizontal bar 102 located at the bottom and is supported on the concrete base plate 12.

[0024] Further, see Figure 2 The first guide member 6 includes a first guide sleeve 601 disposed on the frame 1 and a first guide rod 602 slidably disposed within the first guide sleeve 601. The first guide rod 602 is fixedly connected to the side support plate 4. The first guide sleeve 601 is inclined to the horizontal plane so that the first guide rod 602 is inclined relative to the frame 1.

[0025] Preferably, the first guide sleeve 601 is a hollow cylinder with open ends, the first guide rod 602 is a cylindrical rod, and the second guide rod 902 and the second guide sleeve 901 are fitted with a clearance.

[0026] Further, see Figure 2 The frame 1 is also provided with a first limiting sleeve 16, which is coaxially arranged with the first guiding sleeve 601, and the first guiding rod 602 passes through the first guiding sleeve 601 and is located inside the first limiting sleeve 16.

[0027] Preferably, the first limiting sleeve 16 is a hollow cylinder with openings at both ends, and there is a gap between the first limiting sleeve 16 and the first guide sleeve 601.

[0028] Further, see Figure 2 The first limiting member 8 includes a first limiting screw sleeve 801 disposed on the first guide rod 602. The first limiting screw sleeve 801 is located between the first guide sleeve 601 and the first limiting sleeve 16. The outer diameter of the first limiting screw sleeve 801 is larger than the outer diameters of the first guide sleeve 601 and the first limiting sleeve 16.

[0029] Preferably, the first guide rod 602 has an external thread on one end inside the first limiting sleeve 16, and the first limiting sleeve 801 is connected to the first guide rod 602 by a thread.

[0030] Preferably, the side pusher 7 and the top pusher 10 both adopt the hydraulic rods in the existing structure. The side pusher 7 and the top pusher 10 are fixedly connected to the frame 1. The tilt angle of the side pusher 7 relative to the frame 1 is consistent with the tilt angle of the first guide rod 602 relative to the frame 1.

[0031] In the above configuration, multiple sets of the first guide sleeve 601, the first limiting sleeve 16, and the first limiting rod are provided. Since the side support rods are located on both sides of the frame 1, subsequent demolding needs to be considered during the process of supporting the pouring of the culvert sidewall. Furthermore, the side support plate 4 and the top support plate 5 are interlocked without gaps after movement to support the pouring of the culvert sidewall and top slab. Therefore, the movement path of the side support plate 4 is an inclined straight line. When the side support plate 4 is inclined relative to the frame 1, it is pushed towards or away from the frame 1 by the side pusher 7. When the side support plate 4 moves away from the frame 1, the height of the side support plate 4 and the distance from the frame 1 both increase (in the formwork support state). When the side support plate 4 moves towards the frame 1, the height of the side support plate 4 and the distance from the frame 1 both decrease (in the demolding state). The two sets of side support plates 4 are pushed by the two sets of side pushers. Part 7 controls the direction of movement, reducing the number of hydraulic rods used, lowering costs, and facilitating maintenance. After the side pusher 7 pushes the side support plate 4 into place, the first limiting sleeve 801 is rotated to move towards the first limiting sleeve 16 and abut against it, thereby restricting the freedom of the side support plate 4 to move towards the frame 1. After the concrete is poured into the side wall, the concrete applies a compressive force to the side support plate 4 towards the frame 1. The side pusher 7, the first guide rod 602, and the first limiting sleeve 801 provide support for the side support plate 4, ensuring that the position of the side support plate 4 is fixed and providing support for the concrete pouring of the side wall. After the side wall concrete solidifies, the first limiting sleeve 801 is rotated away from the first limiting sleeve 16, releasing the restriction on the first guide rod 602. The side pusher 7 then moves the side support plate 4 towards the frame 1, completing the demolding.

[0032] In one embodiment, see Figure 2 The second guide member 9 includes a second guide sleeve 901 disposed at the top of the frame 1 and a second guide rod 902 slidably located within the second guide sleeve 901. The second guide sleeve 901 is disposed perpendicular to the top of the frame 1. The second guide rod 902 is fixedly connected to the top support plate 5.

[0033] Preferably, the second guide sleeve 901 is a hollow cylinder with openings at both ends. To facilitate the movement of the second guide rod 902 within the second guide sleeve 901, the top of the frame 1 is provided with a sliding hole that communicates with the interior of the second guide sleeve 901. The second guide rod 902 passes through the second guide sleeve 901 and the sliding hole, which is located on the crossbar 102.

[0034] Preferably, multiple sets of second guide sleeves 901 are arranged at intervals, and the number of second guide rods 902 is the same as the number of second guide sleeves 901.

[0035] Further, see Figure 2 The top of the frame 1 is provided with a support plate 17, and the top pusher 10 is located on the support plate 17. The end of the top pusher 10 away from the support plate 17 is fixedly connected to the top support plate 5.

[0036] Preferably, the support plate 17 is located at the top center of the frame 1, and the support plate 17 is fixedly connected to the two sets of crossbars 102. The bottom end of the top pusher 10 is fixedly connected to the support plate 17, which can be done by bolt connection.

[0037] Further, see Figure 2 The second limiting member 11 includes a second limiting screw sleeve disposed on the second guide rod 902. The outer diameter of the second limiting screw sleeve is larger than the outer diameter of the second guide sleeve 901. The second limiting screw sleeve is threadedly connected to the second guide rod 902.

[0038] Preferably, the outer wall of the second guide rod 902 near the second guide sleeve 901 is provided with an external thread.

[0039] Further, see Figure 2 The top support plate 5 has a first locking platform 18 at both ends, and the side support plate 4 has a second locking platform 19 at its end. The first locking platform 18 and the second locking platform 19 are engaged to engage the top support plate 5 and the side support plate 4.

[0040] Preferably, both the first card holder 18 and the second card holder 19 are "L" shaped structures, with the first card holder 18 located below the second card holder 19.

[0041] In the above configuration, multiple sets of the second guide sleeve 901, the second limiting screw sleeve, and the second limiting rod are provided. The top support plate 5 is used to provide support for the concrete pouring of the bottom slab of the culvert. During the support process, the top support plate 5 and the side support plate 4 are engaged by the first locking platform 18 and the second locking platform 19 without leaving any gaps. The first locking platform 18 is located below the second locking platform 19. Under the push of the top pusher 10, the top support plate 5 moves up or down. During the upward movement of the top support plate 5, the second limiting rod moves up accordingly, and the second limiting screw sleeve moves up accordingly. After the top support plate 5 moves up to the predetermined position, the second limiting screw sleeve is rotated to move down and abut against the second guide sleeve 901, restricting the freedom of the top support plate 5 to move toward the frame 1, thus providing support for the concrete pouring of the top slab. During the demolding process, the second limiting screw sleeve is rotated to move up and separate from the second guide sleeve 901. The top pusher 10 drives the top support plate 5 to move down. After the top support plate 5 separates from the side support plate 4, the side support plate 4 is then removed.

[0042] In one embodiment, see Figure 2The movable component 2 includes a connecting shaft 201 movably disposed at the bottom end of the frame 1, a movable wheel 202 disposed on the connecting shaft 201, a bearing 203 between the connecting shaft 201 and the frame 1, and a connecting frame 204 between the movable wheel 202 and the connecting shaft 201.

[0043] Preferably, the bottom end of the frame 1 is provided with a through hole, the bearing 203 is fixedly installed in the through hole, and one end of the connecting shaft 201 is fixedly connected to the inner ring of the bearing 203.

[0044] Preferably, the connecting frame 204 has a "U" shaped structure, and the movable wheel 202 rotates within the connecting frame 204.

[0045] Further, see Figure 2 The steering component 3 includes a pusher frame 301 slidably mounted on the frame 1, a rack 302 mounted on the pusher frame 301, a gear 303 meshing with the rack 302 on the connecting shaft 201, and a linear pusher 20 between the frame 1 and the pusher frame 301. Under the action of external force, the linear pusher 20 drives the pusher frame 301 to reciprocate, so that the rack 302 meshes with the gear 303 to drive the moving wheel 202 to rotate circumferentially.

[0046] Preferably, the pusher frame 301 has a "U" shaped structure, and two sets of racks 302 are respectively located at the ends of the pusher frame 301.

[0047] Preferably, four sets of movable wheels 202, connecting shafts 201, and gears 303 are provided.

[0048] Preferably, the linear actuator 20 uses a hydraulic rod in an existing structure.

[0049] Preferably, the frame 1 is provided with two sets of limiting blocks 21, and the push frame 301 is located between the two sets of limiting blocks 21. After the push frame 301 is moved by the linear pusher 20, it abuts against one of the sets of limiting blocks 21, which can limit the formation of the push frame 301, thereby controlling the angle at which the rack 302 drives the gear 303 to rotate.

[0050] In the above configuration, the end of the connecting shaft 201 away from the moving wheel 202 passes through the bottom crossbar 102. The gear 303 is located at the upper end of the bottom crossbar 102, and the bearing 203 is located at the bottom end of the bottom crossbar 102. A limiting sleeve 22 is provided on the bottom crossbar 102, and the pusher 301 is located inside the limiting sleeve 22, so it can only move linearly back and forth. The distance between the two sets of limiting blocks 21 and the pusher 301 is the same as the circumference of the gear 303, that is, the pusher 301 is located in the middle of the two sets of limiting blocks 21. During the process of the linear pusher 20 driving the pusher 301 to move, the rack 302... Engaging with gear 303, the linear motion is converted into rotational motion. After the push frame 301 abuts against the limit block 21, gear 303 rotates half a turn (90°), causing the moving wheel 202 to rotate 90°. This allows the forward direction of the moving wheel 202 to be changed to be parallel or perpendicular to the crossbar 102, thus facilitating the radial or axial movement of the frame 1 towards the culvert. This also facilitates the adjustment of the frame 1's position, ensuring that the two sets of side support plates 4 are symmetrically positioned in the culvert. After the side support plates 4 move towards the sidewall of the culvert, they can abut against the edges of the two sets of concrete base plates 12, providing support for the sidewall.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
