Description

Technical Field

[0001] The utility model belongs to the field of asphalt spreading, in particular to an operation auxiliary device for a bridge deck asphalt construction vehicle. Background Art

[0002] As my country has vigorously developed infrastructure in recent years, more and more new bridges have been built. Asphalt pavement has many advantages such as smooth surface, comfortable driving, low vibration, low noise, wear resistance, no dust and easy cleaning, etc., almost all bridges now use asphalt pavement.

[0003] At present, asphalt bridge deck construction is carried out with asphalt construction vehicles. Figure 1 As shown, the asphalt construction vehicle 8 comprises a vehicle body 81 and a tail baffle 82 located at the rear of the vehicle body 81 for blocking the rear opening. The top end of the tail baffle 82 is hinged to the rear of the vehicle body 81. After the asphalt construction vehicle 8 transports the asphalt material to the construction site, as shown in FIG. Figure 2 As shown, the carriage 81 of the asphalt construction vehicle 8 is lifted up, and the head of the carriage 81 is lifted up, so that the bottom plate of the carriage 81 is inclined. At this time, an opening is formed between the rear of the carriage 81 and the rear baffle 82, and the asphalt in the carriage 81 flows out from the opening to the road surface. The asphalt transport vehicle 8 pours the asphalt from the opening while moving, and paving is achieved by controlling the vehicle speed. The size of the opening is determined by two factors: first, the height of the carriage 81 of the asphalt transport vehicle 8; and second, the thrust of the asphalt on the rear baffle 82 when the asphalt passes through the opening. Since the amount of asphalt poured from the carriage to the opening position is difficult to control, it affects the size of the opening, so that the amount of asphalt coming out of the opening is difficult to control, resulting in a serious problem of uneven paving.

[0027] Bridge deck asphalt construction vehicle operation auxiliary device, such as Figure 3 and Figure 4 As shown, it includes an asphalt material box 1 and a material guide trough 2; the material guide trough 2 includes a front baffle 21, a left end plate 22 located at the left end of the front baffle 21, and a right end plate 23 located at the right end of the front baffle 21, and is surrounded by the front baffle 21, the left end plate 22 and the right end plate 23 to form a through groove that passes through from top to bottom; a connecting plate 24 adapted to the rear of the asphalt construction vehicle is respectively provided on the other side where the left end plate 22 is connected to the front baffle 21 and the other side where the right end plate 23 is connected to the front baffle 21;

[0028] The asphalt material box 1 has a hollow box structure; the material guide trough 2 is arranged at the top of the asphalt material box 1, and the bottom end of the through trough is connected to the inner cavity of the asphalt material box 1, and a discharge port 3 connected to the inner cavity of the asphalt material box 1 is arranged at the bottom of the asphalt material box 1; the through trough of the material guide trough 2, the inner cavity of the asphalt material box 1 and the discharge port 3 form an asphalt paving channel.

[0029] The bridge deck asphalt construction vehicle operation auxiliary device disclosed in the utility model is used in conjunction with the asphalt construction vehicle, and the connecting plate 24 of the material guide trough 2 is used to be connected to the rear of the vehicle compartment of the asphalt construction vehicle.

[0030] Asphalt construction truck Figure 1 As shown, it includes a carriage 81 and a tail baffle 82 blocking the rear of the carriage. Figure 5 As shown, the connecting plate 24 on the left side of the material guide trough 2 is installed on the left side of the rear of the carriage 81, the connecting plate 24 on the right side of the material guide trough 2 is installed on the right side of the rear of the carriage 81, and the front baffle 21 is in front of the baffle 82 at the rear of the asphalt construction vehicle. It should be confirmed that the length of the material guide trough 2 matches the width of the carriage 81. In this way, a passage closed on all sides can be formed between the carriage 81 and the material guide trough 2. When the carriage 81 is lifted and discharged, an outlet is formed between the rear baffle 82 and the rear of the carriage 81. The front baffle 21 of the material guide trough 2 can also limit the rear baffle 82, controlling the rear baffle 82 to flip and increase the outlet under the extrusion of the asphalt material. The asphalt in the carriage 81 enters the material guide trough 2 through the outlet, flows into the asphalt material box 1 through the channel of the material guide trough 2, and then flows out from the discharge port 3 of the asphalt material box 1. In this way, an asphalt material channel enclosed on all sides is formed by the material guide trough 2, the vehicle rear baffle 82 and the asphalt material box 1, so that the asphalt road can only be discharged through the discharge port 3, thereby avoiding leakage of asphalt material. At the same time, since the discharge port 3 of the asphalt material box 1 is of fixed size and the capacity of the asphalt material box 1 is much smaller than the capacity of the vehicle body 81, when the asphalt material box 1 is filled with asphalt, the asphalt will flow out evenly through the discharge port 3, that is, the amount of asphalt coming out of the discharge port 3 is relatively easier to control, which is more conducive to uniform paving.

[0031] The connecting plate 24 can be directly welded to the carriage 81. In this embodiment, in order to facilitate disassembly and replacement, preferably, a carriage mounting hole 24A is vertically provided on the connecting plate 24. The connecting plate 24 is connected to the rear of the carriage 81 by a connecting bolt assembly installed in the carriage mounting hole 24A, which is convenient for disassembly and removal.

[0032] When the width of the carriage 81 is constant, if the connecting plate 24 is located in the material guide trough 2 in the transverse direction, that is, the connecting plate 24 on the left side is located on the left side of the left end plate 22, and the connecting plate 24 on the right side is located on the right side of the right end plate 23, the through-channel width of the material guide trough 2 will be reduced. In order not to affect the spatial size of the through-channel, preferably, the connecting plate 24 is a folded edge folded inward in the transverse direction of the material guide trough 2. That is, the connecting plate 24 on the left side is located on the right side of the left end plate 22, and the connecting plate 24 on the right side is located on the left side of the right end plate 23.

[0033] The front baffle 21 can be a whole square plate. In order to reduce the overall weight of the bridge deck asphalt construction vehicle operation auxiliary device, preferably, a window 21A is opened on the front baffle 21 which vertically penetrates the top of the front baffle 21, and the window 21A divides the front baffle 21 into a bottom baffle area 21B located at the bottom of the window 21A, a left baffle area 21C located on the left side of the window 21A, and a right baffle area 21D located on the right side of the window 21A; the left baffle area 21C and the right baffle area 21D are symmetrical about the window 21A.

[0034] The window 21A may be square, but in order to reduce the degree of deformation of the front baffle 21 due to the action of the rear baffle 82 and the asphalt material, preferably, the window 21A is trapezoidal in shape with a larger upper portion and a smaller lower portion along the vertical direction.

[0035] The discharge port 3 is located at the bottom of the front side of the asphalt tank 1 .

[0036] In order to facilitate workers to stand and assist in asphalt construction, preferably, an operating platform 4 is provided on the front side of the material guide trough 2. In order to avoid the operating platform 4 interfering with the discharge of the material outlet 3, the height of the operating platform 4 is higher than the position of the material outlet 3. In order to avoid the problem that the operating platform 4 may hit the ground due to the rotation of the carriage 81 during the dumping process, the operating platform 4 is connected to the material guide trough 2 through a suspension rod 5, the bottom end of the suspension rod 5 is fixed to the operating platform 4, and the top end is suspended and hinged to the material guide trough 2; and a driving mechanism is provided between the operating platform 4 and the asphalt tank 1 to drive the operating platform 4 to rotate away from the asphalt tank 1.

[0037] The driving mechanism can be a hydraulic cylinder or a pneumatic cylinder supported between the asphalt tank 1 and the operating platform 4. In order to save costs, preferably, the driving mechanism includes an adjusting screw 7 threadedly connected to the middle of the boom 5. The adjusting screw 7 passes through one end of the boom 5 and rests against the asphalt tank 1, and a driving handle is provided at the other end.
