Technical Field
[0001] The utility model relates to the technical field of waterproof concrete construction between ballastless track lines, in particular to a tool for waterproof concrete construction between ballastless track lines. Background Art
[0002] With the rapid development of high-speed railway construction, the proportion of ballastless track in high-speed railway construction is increasing, and the proportion of waterproof construction between ballastless tracks is also increasing synchronously. At present, most of the waterproof concrete construction between ballastless tracks is pumped by pump trucks, which has problems such as uneven distribution, easy pollution of other concrete structures, difficulty in distributing materials between lines, and low pouring efficiency. Patent CN210194432U discloses a self-propelled waterproof concrete transport vehicle for high-speed railways, including a transport frame, a mobile wheel set, a hopper, a fixed chute, a movable chute, a limit roller, a generator, a control box, etc. Among them, the fixed chute meets the distribution of the middle part of the line, and the movable chute is in a movable form, which is convenient for the distribution of concrete on both sides of the line, and completely avoids the situation where the crane uses the hopper to repeatedly lift and change positions, making the construction safe and fast, and the concrete paving uniform. However, the transport vehicle still has the following problems: (1) When switching between the lines and the two sides of the lines (line edges), the entire movable chute needs to be moved. The movable chute is heavy and inconvenient to move. In addition, there is no fixed connection between the movable chute and the transport frame. The movable chute is tilted on the transport frame, which easily leads to an unstable connection. (2) When laying concrete on both sides of the lines, concrete can only be laid on one side separately, and then on the other side, which is inefficient. (3) The limit roller is fixedly connected to the transport frame. When the line spacing changes or when constructing a curved section, the limit roller cannot be limited on the inner side of the ballastless track. Summary of the invention

Furthermore, upper cross beams and upper longitudinal beams are welded between the columns around the hopper, and the upper cross beams and upper longitudinal beams are welded to the hopper as a whole, so that the hopper is stably installed on the construction frame.
[0028] In this embodiment, there are four sets of running wheel groups and they are installed at the four corners of the bottom of the construction frame, and the running wheel groups on both sides of the construction frame are respectively supported on the ballastless track 10 on both sides of the line, driving the construction frame to run on the ballastless track. Specifically, the two sets of running wheel groups at the front of the construction frame or the two sets of running wheel groups at the rear are connected to a drive motor 8, which is controlled by a remote control. When carrying out material laying construction, the drive motor is controlled by a remote control to pull the running wheel forward or backward. Preferably, a generator 9 is placed on the chassis of the construction frame, and the generator is connected to the drive motor to provide power for driving the construction tooling.
[0029] There are two guide wheel groups, which are symmetrically installed at the bottom of the construction frame, so that the guide wheels of the two guide wheel groups are respectively in contact with the inner side of the ballastless track on both sides of the line, and the construction frame is guided. In this embodiment, the guide wheel group is installed at the bottom of the construction frame through a vertical adjustment rod 11 and a diagonal brace rod 12. Specifically, the length of the vertical adjustment rod is adjustable, the top end of the vertical adjustment rod is fixed to the bottom of the construction frame, and the bottom end of the vertical adjustment rod is fixedly connected to the guide wheel group, so that the guide wheel of the guide wheel group is in contact with the inner side of the ballastless track, and the two ends of the diagonal brace rod are hinged to the bottom of the guide wheel group and the construction frame. Further, the bottom of the construction frame and the guide wheel group are correspondingly provided with lifting ears, and the two ends of the diagonal brace rod are hinged to the lifting ears. When the line spacing is found to be slightly changed or when constructing a curved section, the guide wheel group can be adjusted by adjusting the length of the vertical adjustment rod and the angle of the diagonal brace rod, so that the guide wheel group can adapt to the line spacing change and the working conditions during the curved section construction. Preferably, the vertical adjustment rod comprises an outer tube and an inner rod which fit together, and bolt holes are distributed on the outer tube and the inner rod. After the length of the vertical adjustment rod is adjusted, the outer tube and the inner rod are connected and fixed by passing the alignment bolt through the bolt hole. The vertical adjustment rod can also be a telescopic cylinder.
[0030] In this embodiment, the hopper is fixed to the upper part of the construction frame, the middle discharge port is fixed to the lower part of the construction frame, and the two side chutes are obliquely and symmetrically installed on both sides of the construction frame and are both located between the hopper and the middle discharge port. In this embodiment, the middle discharge port is connected around with fixing rods 14, that is, four fixing rods are connected to form a frame structure, which is fixedly connected to the rectangular frame of the construction frame through the fixing rods.

Specifically, the upper two sides of the fixed chute are fixed to the two columns at the corresponding positions of the construction frame by bolts, the middle of the fixed chute is fixed to the rectangular frame of the construction frame, and the fixed chute extends to the outside of the line. The lower parts of the two adjustable chutes are hinged to the two columns at the corresponding positions of the construction frame by pins, that is, the two columns connected by the fixed chute, and the two adjustable chutes are respectively connected to the upper parts of the two fixed chutes, and the upper parts of the two adjustable chutes can be detachably suspended on the hopper or the construction frame. When the adjustable chute is suspended on the hopper or the construction frame, the adjustable chute is located below the hopper discharge port and above the middle discharge port. At this time, the concrete in the hopper is distributed outside the line through the adjustable chute and the fixed chute; when the adjustable chute is not suspended on the hopper or the construction frame, the upper part of the adjustable chute falls and rests on the middle discharge port. At this time, the concrete in the hopper flows into the discharge port through the adjustable chute, thereby distributing the concrete in the line.
[0032] In this embodiment, the adjustable chute is suspended on the hopper. Specifically, a suspension rod 13 is welded below the hopper, and the adjustable chute is suspended on the suspension rod. Furthermore, each adjustable chute is correspondingly provided with two suspension rods, which suspend the upper two sides of the adjustable chute respectively.

[0033] In this embodiment, two hoppers are symmetrically arranged on the left and right. When the two adjustable chutes are suspended on the hopper or the construction frame, the two adjustable chutes are respectively located below the two hopper discharge ports, so that the materials can be distributed to both sides of the line at the same time. When the two adjustable chutes are not suspended on the hopper or the construction frame, the upper parts of the two adjustable chutes fall down and rest on the middle discharge port, and the materials are distributed to the middle discharge port at the same time, which has high construction efficiency.
