[0002] With the rapid development of modern transportation construction, bridge engineering plays an increasingly important role in the national economy. In bridge construction, the installation of the bridge deck system is one of the key links. The bridge deck system mainly includes components such as bridge deck panels, crash barriers, and drainage facilities. The installation quality of the bridge directly affects its performance and safety.

[0003] Currently, when laying U-shaped grooves on both sides of the bridge deck, the U-shaped grooves are hoisted to the designated position by hoisting equipment. In harsh environments, the laying components swing greatly. Due to the lack of precise positioning methods, the installation quality may be affected by the operator's skill level, resulting in inconsistent installation quality, affecting the overall installation quality and reducing installation efficiency. Therefore, we have proposed a prefabricated bridge deck positioning and installation equipment to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figs. 1-3 As shown:

[0032] The precast bridge deck system positioning and installation equipment includes a U-shaped connector 101, and a handle 102 is fixed to the top of the U-shaped connector 101;

[0033] The clamping mechanism 2 is installed on the U-shaped connector 101 and is used to clamp and fix this device to the laying component.

[0034] Clamping mechanism 2 includes:

[0035] The first electric push rod 201 is provided in two sets and is fixedly installed on both sides of the U-shaped connecting seat 101 respectively;

[0036] The clamping plate 202 is fixedly installed at the output end of the first electric push rod 201;

[0037] The positioning and guiding mechanism 3 is installed on the U-shaped connecting seat 101 and is used to align, position and guide the installation of the laying components.

[0038] Positioning and guiding mechanism 3 includes;

[0039] Two sets of L-shaped plates 301 are provided and are respectively installed and fixed on both sides of the U-shaped connector 101;

[0040] The second electric push rod 302 is fixedly installed on one side of the L-shaped plate 301 by bolts;

[0041] The horizontal seat plate 304 is fixedly installed at the output end of the second electric push rod 302;

[0042] The first roller 305 is mounted on the horizontal seat plate 304. A rolling groove adapted to the first roller 305 is provided on one side of the horizontal seat plate 304. The first roller 305 is rotatably mounted in the rolling groove provided in the horizontal seat plate 304 via a rotating shaft. A first multi-section telescopic rod 303 arranged symmetrically is fixed between the horizontal seat plate 304 and the L-shaped plate 301.

[0043] In this implementation plan: the precast bridge deck system positioning and installation equipment has a handle 102 on the top of the U-shaped connecting seat 101 during use. The handle 102 facilitates the picking up and putting down of the device. The operator can hold the handle 102 to clamp the U-shaped slot of the U-shaped connecting seat 101 onto the paving component (i.e., the U-shaped groove seat). Then, the first electric push rod 201 is activated, thereby driving the clamping plate 202 to move. The two sets of clamping plates 202 can clamp the two sides of the paving component to fix the device on the paving component.

[0044] Subsequently, the operator can use the hoisting equipment to lift the laying component and place it in the designated laying area. Between the two sets of first rollers 305, the operator can manually push the laying component to ensure that its splicing surface accurately corresponds and fits with the splicing surface of the already fixed laying component.

[0045] Next, the second electric push rod 302 is activated, which drives the horizontal seat plate 304 to move. The movement of the horizontal seat plate 304 will drive the first roller 305 to move, so that the two sets of first rollers 305 can clamp the two sides of the laying part. The distance between the two sets of first rollers 305 is matched with the clamping distance of the clamping plate 202, ensuring that when the two sets of first rollers 305 are in contact with the two sides of the laying part, the laying part can be aligned and flush with the already completed laying part.

[0046] Subsequently, the second electric push rod 302 is stopped. At this time, the equipment positions and guides the laying component. The worker continues to assist in moving the laying component down until it is in contact with and fixed to the ground concrete. During the process of the laying component moving down, the friction generated by the first roller 305 contacting the laying component can drive the first roller 305 to roll on the cross plate 304. This can reduce the friction and improve the smoothness of the downward movement while the laying component moves down.

[0047] In addition, a first multi-section telescopic rod 303 is fixedly installed between the horizontal seat plate 304 and the L-shaped plate 301. When the horizontal seat plate 304 moves, it can drive the first multi-section telescopic rod 303 to extend and retract. The first multi-section telescopic rod 303 can provide support points at both ends of the horizontal seat plate 304, which improves the stability of the connection and installation of the horizontal seat plate 304 and the second electric push rod 302.

[0048] This solution, through the coordinated action of clamping mechanism 2 and positioning guide mechanism 3, can effectively reduce the swaying of the U-shaped channel seat of the laying component caused by environmental factors (such as wind), ensuring that the U-shaped channel seat is accurately installed on both sides of the bridge deck. This greatly improves the installation accuracy and reduces the adjustment time during the installation process, thereby significantly improving the efficiency of the entire installation process.

[0049] It should be noted that pressure sensors are also installed on the first roller 305 and the clamping plate 202. When the pressure is reached during extrusion, the operation of the second electric push rod 302 and the first electric push rod 201 can be stopped. All electrical equipment involved in this product is powered by an external power source (portable battery) and can be flexibly charged. The solution also includes a controller and a control switch, which are set on the U-shaped connector 101. During use, the operation of each electrical device can be started by the control switch. The power connection method of each electrical device is a mature existing technology and is well known to those skilled in the art, so it will not be described in detail here.

[0050] Meanwhile, all aspects of the pressure sensor not described in detail in this specification are existing technologies known to those skilled in the art. For specific connection methods, functions, and structures, please refer to patent document CN112721194A.

[0051] Furthermore;

[0052] In an optional embodiment, anti-slip teeth 203 are provided on the side of the two sets of clamping plates 202 that are close to each other.

[0053] In this embodiment: Since anti-slip teeth 203 are provided on the side of the two sets of clamping plates 202 that are close to each other, the setting of these anti-slip teeth 203 increases the friction between the clamping plate 202 and the laying component contact surface, thereby improving the stability of clamping.

[0054] Furthermore;

[0055] In an optional embodiment, a rubber cushioning layer is fixed to the outer surface of the first roller 305.

[0056] In this embodiment: At the same time, the outer surface of the first roller 305 is provided with a rubber buffer layer. When the first roller 305 clamps the bridge deck paving component, this rubber buffer layer can play a clamping and buffering role, protecting the paving component from damage.

[0057] Furthermore;

[0058] In an optional embodiment, a support sliding mechanism 4 is also installed on the U-shaped connecting seat 101. The support sliding mechanism 4 includes a screw 401 threadedly connected to the U-shaped connecting seat 101. The U-shaped connecting seat 101 is threadedly connected to the screw 401 through a threaded hole. A U-shaped plate 402 is rotatably mounted on the bottom end of the screw 401 via a bearing. A second roller 403 symmetrically arranged is rotatably mounted inside the U-shaped plate 402 via a rotating shaft. A second multi-section telescopic rod 404 symmetrically arranged is fixedly installed between the U-shaped plate 402 and the U-shaped connecting seat 101.

[0059] In this embodiment: During use, the operator moves the U-shaped plate 402 downward by turning the screw 401. The downward movement of the U-shaped plate 402 simultaneously moves the second roller 403 downward, and the U-shaped plate 402 also drives the second multi-section telescopic rod 404 to extend and retract. The second multi-section telescopic rod 404 is designed to limit the movement of the U-shaped plate 402, ensuring that the U-shaped plate 402 can move vertically downward. When the second roller 403 on the U-shaped plate 402 contacts the top surface of the U-shaped groove seat, the operator can move the equipment laterally to continue laying the next set of U-shaped groove seats. At this time, the friction between the second roller 403 and the U-shaped groove seat drives the second roller 403 to roll. The supporting sliding mechanism 4 is equivalent to a mobile vehicle, allowing the equipment to slide laterally along the laying track directly on the top of the U-shaped groove seat, eliminating the need for frequent lifting or repositioning by the operator, further reducing the labor intensity of the workers.

[0060] Furthermore;

[0061] In an optional embodiment, the bottom of the U-shaped connector 101 is provided with a plurality of movable slots, and a movable wheel 103 is provided in the movable slot. The movable wheel 103 is rotatably connected to the U-shaped connector 101 through a rotating shaft.

[0062] In this embodiment, the bottom of the U-shaped connecting seat 101 is equipped with multiple casters 103. When the equipment needs to be moved, the casters 103 can contact the ground and roll, thus enabling movement. This reduces the labor intensity of the workers when moving the equipment.

[0063] The working principle and usage process of this utility model are as follows: This precast bridge deck system positioning and installation equipment, in use, has a handle 102 on the top of the U-shaped connecting seat 101. The U-shaped slot of the U-shaped connecting seat 101 is clamped onto the paving component (i.e., the U-shaped groove seat). Then, the first electric push rod 201 is activated, thereby driving the clamping plate 202 to move. The two sets of clamping plates 202 can clamp the two sides of the paving component to fix this equipment on the paving component. Subsequently, the operator can use the hoisting equipment to lift the paving component and hoist it to the designated paving area. Between the two sets of first rollers 305, the operator can manually push the paving component so that its splicing surface is aligned with the already fixed paving component. The splicing surfaces are accurately aligned and fitted; then the second electric push rod 302 is activated, which drives the horizontal seat plate 304 to move. The movement of the horizontal seat plate 304 will drive the first roller 305 to move, so that the two sets of first rollers 305 can clamp the two sides of the laying component. The distance between the two sets of first rollers 305 is adapted to the clamping distance of the clamping plate 202, ensuring that when the two sets of first rollers 305 are attached to the two sides of the laying component, the laying component to be laid can be aligned and flush with the already laid component; then, the activation of the second electric push rod 302 is stopped. At this time, the equipment performs positioning and guiding functions for the laying component, and the workers continue to assist in moving the laying component down until it is attached to and fixed with the ground concrete.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
