DETAILED DESCRIPTION

[0024] The following is a combination of specific implementation cases and attached Figure 1-Figure 3 The present invention is further described below, but the present invention is not limited to these embodiments.

[0025] When installing bridge beam slabs using traditional hoisting methods, it is easy to cause the bridge beam slabs to twist in the air, making it difficult to achieve accurate docking of the bridge beam slabs in the horizontal direction and difficult to ensure the rapid and effective assembly of the bridge beam slabs. Referring to Figures 1 to 3 As shown, a bridge beam slab installation auxiliary device is proposed, including a base 1. The base 1 is composed of a bottom plate and two vertical plates perpendicular to the bottom plate. The two vertical plates are respectively vertically installed at the front and rear ends of the upper surface of the bottom plate. The bottom plate and the two vertical plates form a "U"-shaped semi-enclosed structure. The bridge beam slab body can be translated horizontally within the inner cavity of the semi-enclosed structure. First slide rails 2 and second slide rails 3 are respectively arranged on the outer walls of the two vertical plates along the horizontal direction. A moving seat 4 is slidably embedded in the inner cavity of the first slide rail 2. Through the setting of the first slide rail 2, it can ensure that the moving seat 4 moves horizontally without tilting up and down. The top of the moving seat 4 is positioned with the bridge beam slab body 15. Driven by the moving seat 4, the bridge beam slab body 15 can move synchronously horizontally to achieve the translation of the bridge beam slab body 15 or the docking of the free ends of adjacent bridge beam slab bodies 15; the second slide rail 3 is located above the first slide rail 2, and the first slide rail 2 and the second slide rail 3 are arranged parallel to each other, so as to ensure that when the components move along the inner cavities of the first slide rail 2 and the second slide rail 3, the components can move straight horizontally without interference.

[0026] Referring to Figure 2 As shown, side plates 5 are respectively vertically installed on the front and rear sides of the moving seat 4. A moving rod 6 is vertically penetrated through the outer wall of the side plate 5 from front to back, that is, the moving rod 6 can move back and forth along the outer wall of the side plate 5 under the action of an external force. One end of the moving rod 6 is installed with a positioning plate 7. The movement of the moving rod 6 can drive the positioning plate 7 to move synchronously, and the positioning plate 7 corresponds to the side wall position of the bridge beam slab body 15. When the positioning plate 7 gradually approaches and fits the side wall of the bridge beam slab body 15, the bridge beam slab body 15 can be clamped and positioned; an elastic cushion plate 8 is installed on the side opposite to the side wall of the bridge beam slab body 15 of the positioning plate 7. The elastic cushion plate 8 is an elastic leather pad in the existing market, and anti-slip bumps are uniformly arranged on its outer wall in a rectangular array. By fitting the anti-slip bumps on the outer wall of the elastic cushion plate 8 with the side wall of the bridge beam slab body 15, the friction between the positioning plate 7 and the bridge beam slab body 15 can be increased, promoting the bridge beam slab body 15 to be more stably positioned at the positioning plate 7; the other end of the moving rod 6 is installed with a driving plate 9, and a lead screw 10 is threadedly penetrated through the outer wall of the driving plate 9 from front to back, and one end of the lead screw 10 is rotatably connected to the side wall of the side plate 5 through a bearing. A limiting rod 12 is vertically installed on the side wall of the side plate 5, and the limiting rod 12 penetrates through the outer wall of the driving plate 9; in order to facilitate the rotation of the lead screw 10, a hand wheel 11 is installed at the other end of the lead screw 10. By rotating the hand wheel 11, the rotation of the lead screw 10 can be achieved more labor-saving and convenient.

[0027] The steps of clamping and positioning the bridge beam and slab body 1 by two positioning plates 7 are as follows: by driving the lead screw 10 to rotate, the driving plate 9 is driven to gradually approach the outer wall of the side plate 5 along the outer wall of the limit rod 12. At the same time, the movement of the driving plate 9 drives the moving rod 6 and the positioning plate 7 to gradually approach the side wall of the bridge beam and slab body 15 until the elastic pad 8 on the outer wall of the positioning plate 7 is in contact with the side wall of the bridge beam and slab body 15, thereby realizing the positioning of the side wall of the bridge beam and slab body 15 by the positioning plate 7, ensuring that the bridge beam and slab body 15 is stably positioned on the upper surface of the moving seat 4.

[0028] Specifically, the lead screw 10 and the limit rod 12 are symmetrically arranged with the central axis of the moving rod 6 as the axis, so as to ensure that when the lead screw 10 rotates, the drive plate 9 is prompted to move straight in the front and rear directions, and the drive plate 9 is prompted to move left and right in a relatively balanced manner under the limiting action of the limit rod 12.

[0029] See also Figure 3 As shown, a slide groove 13 is provided at the bottom end of the inner wall of the first slide rail 2, and a wheel body 14 is slidably embedded in the inner cavity of the slide groove 13, and the top end of the wheel body 14 is connected to the bottom end of the outer wall of the moving seat 4. When the moving seat 4 moves, the wheel body 14 can be driven to move along the inner cavity of the slide groove 13 to ensure that the moving seat 4 moves stably and does not tilt forward and backward; specifically, four wheel bodies 14 are provided, and two wheel bodies 14 are a group and are respectively installed on the front and rear sides of the lower surface of the moving seat 4, thereby ensuring that the front and rear two groups of wheel bodies 14 can respectively move stably along the inner cavities of the two slide grooves 13 to ensure that the moving seat 4 is subjected to relative support forces balanced at the four corners during the movement.

[0030] The working principle of the auxiliary device for installing a bridge beam and slab in this embodiment is as follows:

[0031] The bridge beam plate body 15 is placed on the upper surface of the moving seat 4, and the lead screw 10 is driven to rotate by the driving hand wheel 11, thereby driving the driving plate 9 to gradually approach the outer wall of the side plate 5 along the outer wall of the limit rod 12. At the same time, the movement of the driving plate 9 drives the moving rod 6 and the positioning plate 7 to gradually approach the side wall of the bridge beam plate body 15, until the elastic pad 8 of the outer wall of the positioning plate 7 fits with the side wall of the bridge beam plate body 15, thereby realizing the positioning of the positioning plate 7 on the side wall of the bridge beam plate body 15, and ensuring that the bridge beam plate body 15 is stably positioned on the upper surface of the moving seat 4; by pushing the moving seat 4 to move in the horizontal direction, the bridge beam plate body 15 is driven to move horizontally synchronously. At this time, the moving seat 4 moves along the inner cavity of the first slide rail 2, and the moving rod 6 moves along the inner cavity of the second slide rail 3. At the same time, the wheel body 14 installed at the bottom end of the moving seat 4 moves along the inner cavity of the slide groove 13, ensuring the smooth translation of the moving seat 4 and the bridge beam plate body 15, realizing the horizontal movement installation of the free end of the bridge beam plate body 15 and the docking with the adjacent bridge beam plate body 15;

[0032] The utility model can ensure the accurate movement and docking of the bridge beam and slab main body 15 in the horizontal direction, thereby ensuring the rapid and effective assembly of the bridge beam and slab main body 15, avoiding the problem of twisting of the bridge beam and slab main body 15 during the docking process caused by the traditional lifting method, and at the same time, avoiding the front and rear deviation of the bridge beam and slab main body 15 during the movement, so as to ensure that the right free end direction of the bridge beam and slab main body 15 is always straight, so as to facilitate the accurate docking between the subsequent adjacent bridge beam and slab main bodies 15, and can ensure that the moving seat 4 always moves accurately along the horizontal direction without deflecting front and rear or up and down.

[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
