Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, specifically to a trolley with a concrete diversion channel for moving bridges. Background Technology

[0002] During the construction of the invert arch inside the tunnel, a trestle bridge is required. This trestle bridge has a movable traveling vehicle. When the trestle bridge is supported on a support surface, the traveling vehicle moves along the trestle bridge; when the traveling vehicle is supported on the support surface, it drives the trestle bridge to move. This is the function of the traveling vehicle in the existing technology. However, during the invert arch construction, concrete needs to be poured. Concrete diversion requires additional equipment, and more equipment means more space is occupied, undoubtedly increasing the construction difficulty in the confined tunnel space. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a trolley with a concrete guide channel for moving bridges.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mobile trolley with a concrete diversion channel includes a U-shaped body, with lifting support legs on both sides of the body, and a drive mechanism connected to the body to move the body. The trolley is characterized in that: at least one side of the body is provided with a diversion channel for diverting concrete; and the body is provided with an adjustment mechanism for adjusting the diversion direction of the diversion channel.

[0006] Furthermore, the adjustment mechanism includes a support frame, a central support rod, a pitch cylinder, and a swing cylinder. The support frame is fixed to the side of the vehicle body, and the central support rod is rotatably sleeved on the sleeve of the support frame. The inclined bracket at the upper end of the central support rod is hinged to the middle of the bottom surface of the guide channel. The lower end of the pitch cylinder is hinged to the lower end of the central support rod, and the upper end of the pitch cylinder is hinged to the lower or upper end of the bottom surface of the guide channel, for driving the pitch of the guide channel. The two ends of the swing cylinder are respectively hinged to the lugs of the support frame and the central support rod, for driving the guide channel to swing in the horizontal plane.

[0007] Furthermore, the bottom of the support leg is rotatably connected to a movable foot.

[0008] Furthermore, the drive mechanism includes a hydraulic motor fixed to the vehicle body, and a gear is fixed to the output end of the hydraulic motor, which meshes with a rack on the trestle.

[0009] Furthermore, the vehicle body is equipped with upper hanging wheels and lower guide wheels on both sides to cooperate with the trestle.

[0010] This utility model adopts the above technical solution. By setting a concrete diversion channel on the mobile trolley, the mobile trolley can have the function of diverting concrete, thereby reducing the number of construction equipment in the tunnel. The construction space inside the tunnel will not be affected, and the construction of the invert arch is more convenient. In addition, the diversion direction of the diversion channel can be adjusted by the adjustment mechanism, making it more flexible to use. Attached Figure Description

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0012] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] like Figure 1 As shown, this utility model discloses a mobile trolley with a concrete guide channel for a trestle, comprising a U-shaped body 1, which is assembled from steel. Guide sleeves 2 are vertically aligned on both sides of the body 1, and support legs 3 are slidably connected to the guide sleeves 2. The support legs 3 are raised and lowered by lifting cylinders. Movable feet 4 are rotatably connected to the bottom of the support legs 3. The movable feet 4 have adaptive adjustment capabilities, thus adapting to different support surfaces.

[0014] A drive mechanism for moving the vehicle body 1 is connected to the vehicle body 1. Specifically, the drive mechanism includes a hydraulic motor 5 fixed to the vehicle body 1, and a gear 6 fixed to the output end of the hydraulic motor 5. This gear 6 meshes with a rack on the trestle. When the vehicle body 1 is suspended on the trestle, the hydraulic motor 5 drives the gear 6 to rotate, which in turn moves the vehicle body 1 along the trestle. By using the hydraulic motor 5 as the drive mechanism, the hydraulic motor 5 has very little inertia when it stops, thus enabling immediate stopping and minimizing inertial impact on the gear 6 and rack, resulting in a longer service life for the equipment.

[0015] The vehicle body 1 is equipped with upper hanging wheels 7 and lower guide wheels 8 on both sides, which cooperate with the trestle bridge. Through the cooperation of the upper hanging wheels 7 and lower guide wheels 8, the vehicle body 1 forms a clamping guidance method on the trestle bridge, which has extremely high stability.

[0016] At least one side of the vehicle body 1 is provided with a flow guide trough 9. In this embodiment, both sides of the vehicle body 1 are designed with flow guide troughs 9, which are used to guide the concrete. In addition, the vehicle body 1 is provided with an adjustment mechanism 10 for adjusting the flow direction of the flow guide troughs 9. The adjustment mechanism 10 includes a support frame 101, a central support rod 102, a pitch cylinder 103, and a swing cylinder 104. The support frame 101 is fixed to the side of the vehicle body 1. The central support rod 102 is rotatably sleeved on the sleeve of the support frame 101. The inclined frame at the upper end of the central support rod 102 is hinged to the middle of the bottom surface of the guide channel 9. The lower end of the pitch cylinder 103 is hinged to the lower end of the central support rod 102, and the upper end of the pitch cylinder 103 is hinged to the lower or upper end of the bottom surface of the guide channel 9, for driving the pitch of the guide channel 9. The two ends of the swing cylinder 104 are respectively hinged to the lugs of the support frame 101 and the central support rod 102, for driving the guide channel 9 to swing in the horizontal plane.

[0017] The mobile trolley of this invention has the function of guiding concrete, thereby reducing the number of construction equipment in the tunnel, and the construction space inside the tunnel will not be affected, making the construction of the invert arch more convenient; in addition, the guiding direction of the guide channel can be adjusted by the adjustment mechanism, making it more flexible to use.

[0018] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
