[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] A material placing equipment for bridge deck paving, comprising two mobile bases 1, a hydraulic telescopic column 2 is fixedly installed on the upper surface of the mobile base 1, a support frame 3 is fixedly installed between the upper surfaces of the two hydraulic telescopic columns 2, a carrier 4 is slidably installed in the support frame 3, a fixing mechanism for clamping a discharge pipe of a cement mixer truck is arranged in the carrier 4, a walking mechanism 6 is arranged between the carrier 4 and the support frame 3, in order to ensure the stability of the support frame 3 when the hydraulic telescopic column 2 drives the support frame 3 to move up and down, two directional rods 11 are fixedly installed on the upper surface of the mobile base 1, and the directional rods 11 are slidably connected to the support frame 3, so as to ensure the stability of the support frame 3 when it moves up and down;

[0024] The walking mechanism 6 is used to drive the carrier 4 to move left and right in the support frame 3, thereby driving the cement mixer truck discharge pipe clamped in the fixing mechanism to move and lay materials. When laying materials, the carrier 4 moves from the left to the right as one laying formation. After one laying formation is completed, two operators synchronously move the base 1 to adjust the position of the support frame 3 to change the laying area;

[0025] It should be noted that if Figure 1 As shown, two guide rails 31 are fixedly mounted on the upper surface of the support frame 3. Figure 2 As shown, the vehicle 4 includes a bottom plate 41, a through hole 411 is opened at the center of the upper surface of the bottom plate 41, and the through hole 411 is used to install the discharge pipe of the cement mixer truck, and the upper surface of the bottom plate 41 is symmetrically fixed with side plates 42, and the outer surfaces of the side plates 42 are rotatably installed with V-shaped track wheels 421, and the V-shaped track wheels 421 are rollingly set on the corresponding guide rails 31. Through the arrangement of the V-shaped track wheels 421 and the bottom plate 41, the vehicle 4 can be stably slidably set as a whole in the support frame 3;

[0026] like Figure 2 As shown, the fixing mechanism includes a fixing plate 43 and a limiting plate 44. The fixing plate 43 is fixedly installed between the two side plates 42. The limiting plate 44 is in a "J" shape, and a long rod bolt is installed between the limiting plate 44 and the fixing plate 43. When using the fixing mechanism, first place the discharge pipe of the cement mixer truck between the fixing plate 43 and the limiting plate 44, and then use the long rod bolt to tighten the fixing plate 43 and the limiting plate 44, so that the discharge pipe of the cement mixer truck can be fixed in the carrier 4. When installing the discharge pipe of the cement mixer truck, it should be noted that the discharge end of the discharge pipe of the cement mixer truck needs to be passed through the through port 411 to ensure that the cement slurry can be laid on the bridge deck.

[0027] In addition, during the laying process, in order to facilitate the relatively uniform distribution of the materials dropped from the discharge pipe of the cement mixer on the bridge deck, combined with Figure 2 and Figure 3 As shown, a combing plate 5 is symmetrically fixedly installed on the lower surface of the base plate 41, and a triangular material guide plate 51 and a plurality of combing teeth 52 are respectively fixedly installed on the middle and both sides of the lower surface of the combing plate 5. A material passing gap is reserved between two adjacent combing teeth 52. The triangular material guide plate 51 can be used to guide the dropped pulp to both sides, and the plurality of combing teeth 52 can be used to comb the pulp to make the cloth relatively uniform.

[0028] In the process of combing the pulp, in order to prevent the pulp from adhering to the outer surface of the combing teeth 52 and causing blockage in the material passing gap, it is necessary to apply an anti-stick coating on the outer surface of the triangular material guide plate 51 and the combing teeth 52.

[0029] In addition, in order to further compact the scattered slurry and make it more compact with the bridge deck, such as Figure 2 As shown, a fixing frame 53 is fixedly installed on the outer surface of the combing plate 5, and a flattening roller 54 is rotatably installed in the fixing frame 53. The carrier 4 can drive the flattening roller 54 to move during the movement. When the hydraulic telescopic column 2 drives the support frame 3 and the carrier 4 to move downward, it can drive the flattening roller 54 to move downward, thereby compacting the pulp combed and scattered along the way.

[0030] Specifically, the walking mechanism 6 includes a walking motor 61, a gear 62 and a rack plate 63. The walking motor 61 is fixedly mounted on the lower surface of the base plate 41. The gear 62 is sleeved on the outer surface of the output shaft of the walking motor 61, and the gear 62 is meshed and connected with the rack plate 63. The rack plate 63 is fixedly mounted on the lower surface of the support frame 3. After the walking motor 61 is powered on, the gear 62 and the rack plate 63 can be used to drive the carrier 4 to move to the left or right in the support frame 3, thereby achieving the purpose of driving the unloading pipe of the cement mixer truck to move for laying materials.

[0031] When in use, first move the entire equipment to the bridge deck paving, then install the cement mixer truck discharge pipe in the carrier 4 through the fixing mechanism, and then start the travel motor 61 to drive the carrier 4 to move from left to right. During the movement, the cement mixer truck discharge pipe maintains a continuous discharge state, and the dropped slurry is preliminarily combed by the moving combing teeth 52, and then compacted by the flattening rollers 54 to fit the bridge deck, thereby realizing the preliminary distribution of the bridge deck. When the distribution area is changed, the cement mixer truck moves accordingly to maintain the corresponding discharge distance.
