During pouring, a height difference of 10-20mm is likely to occur in the position of the expansion joint, which cannot be measured directly with a traditional level, resulting in a slow concrete pouring speed.

Utility model content

The purpose of this utility model is to solve the shortcomings existing in the prior art, and propose a leveler for controlling the construction height difference of the base plate of the ballastless track. The use of the utility model not only ensures that the height difference between the front and rear of the expansion joint is within 2mm , and it also speeds up concrete placement, reducing the need for workers to add concrete back and forth or remove excess concrete.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

A leveler for controlling the construction height difference of a ballastless track base plate, including a gantry, a level is installed on the top of the horizontal section of the gantry, a groove base is arranged at the bottom of the gantry, and the gantry is folded with the groove base. .

Preferably, the gantry includes a horizontal rod and a vertical rod, the two vertical rods are installed at the ends of the horizontal rod, and the horizontal rod and the vertical rod are vertically arranged.

Preferably, a fixed pin is rotatably inserted into the lower end of the vertical rod, and the fixed pin is rotatably connected to the inner wall of the slot-shaped base. The slot-shaped base and the vertical rod are provided with corresponding through holes, and the through holes are provided with corresponding through holes. activity pin.

Preferably, a pull ring is rotatably connected to the end of the movable pin.

Preferably, the movable pin and the fixed pin are arranged in parallel, and the movable pin and the fixed pin are located in the same vertical plane.

Compared with the prior art, the beneficial effects of the present utility model are: the utility model solves the problem that the leveling device is erected on both sides of the expansion joint when the base plate concrete is poured, and whether the height difference between the front and the rear of the expansion joint can be measured to meet the requirements, the solution is to solve the problem. The traditional level cannot be measured, and the naked eye cannot judge the height difference between the front and rear. Through technical improvement, the use of this level not only ensures that the height difference between the front and rear of the expansion joint is within 2mm, but also speeds up the concrete pouring speed and reduces the number of workers going back and forth. Add concrete or remove excess concrete.

Fig. 1 is the structural representation proposed by the utility model;

Fig. 2 is the side view of Fig. 1;

Figure 3 is a schematic diagram of the working structure of the utility model.

In the figure: vertical rod 1, horizontal rod 2, level 3, groove base 4, movable pin 5, pull ring 6, fixed pin 7.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

Referring to Figures 1-3, this case designs a leveler for controlling the construction height difference of the base plate of the ballastless track, which specifically includes a gantry frame, a level 3 is installed on the top of the horizontal section of the gantry frame, and a groove base 4 is installed at the bottom of the gantry frame. , the gantry frame is foldably connected with the groove base 4, the gantry frame includes a horizontal rod 2 and a vertical rod 1, the two vertical rods 1 are installed at the ends of the horizontal rod 2, and the horizontal rod 2 and the vertical rod 1 are arranged vertically.

Since the position of the expansion joint needs to be set with end formwork when pouring concrete for each unit base plate, it cannot be measured directly with a traditional level, and the height difference between the front and rear cannot be judged with the naked eye. On it, across the expansion joint, use the spirit level 3 to observe whether the two sides of the expansion joint are at the same level. Workers go back and forth to add concrete or remove excess concrete.

The lower end of the vertical rod 1 is rotatably connected with a fixed pin 7, and the fixed pin 7 is rotatably connected to the inner wall of the slotted base 4. The slotted base 4 and the vertical rod 1 are provided with corresponding through holes, and the through holes are provided with corresponding through holes. There is a movable pin 5, unplug the movable pin 5, the vertical rod 1 can freely rotate around the fixed pin 7 relative to the groove base 4, and can be folded and stored for easy carrying. On the contrary, the movable pin 5 can connect the vertical rod 1 and the groove base 4. Relatively fixed for normal use.

A pull ring 6 is rotatably connected to the end of the movable pin 5, which is convenient for pulling the movable pin 5. The movable pin 5 and the fixed pin 7 are arranged in parallel, and the movable pin 5 and the fixed pin 7 are located in the same vertical plane.

The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
