Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a vacuum water absorption device for ballastless track base plates used in ballastless track construction. Background Technology

[0002] The water-cement ratio is the weight ratio of water to cement used in mixing cement paste, mortar, and concrete. The water-cement ratio affects the rheological properties of concrete, the cohesive structure of the cement paste, and its density after hardening. Therefore, the water-cement ratio is a key parameter determining the strength and other physical and mechanical properties of concrete. A vacuum water-absorbing device for ballastless track base plates is a device used in ballastless track construction to quickly remove excess water from concrete. It creates a vacuum environment to accelerate the evaporation and removal of moisture from the concrete, thereby improving the early strength and durability of the concrete.

[0003] Existing vacuum water absorption devices for ballastless track base plates require the following steps: after setting up the device at the work site, a filter cloth is laid first, followed by a water-absorbing pad, and then the water inlet is connected to the pad. During the absorption process, workers need to use steel pipes to press down the four sides of the pad to ensure it adheres tightly to the concrete surface. This process is lengthy and labor-intensive during the entire ballastless track laying process, and the repeated use of steel pipes to press the pad down increases the workload and reduces worker efficiency. Therefore, we propose a vacuum water absorption device for ballastless track base plates. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a vacuum water suction device for ballastless track base plates, so as to solve the problem mentioned in the background art that workers repeatedly use steel pipes to press, which increases the workload of workers and reduces their work efficiency.

[0005] The purpose of this utility model is achieved as follows:

[0006] Similar to existing ballastless track base plate vacuum water suction devices, it also includes a main body with wheels at the bottom and handrails at the rear.

There is a drain valve at the bottom of the water tank. The inner end of the air suction pipe is connected to the vacuum box, and the inner end of the exhaust pipe is connected to the output end of the vacuum box. The water from the water-absorbing pad enters the vacuum box through the air suction pipe and is then discharged through the drain pipe.

[0007] Its features include: a clamping mechanism located on the right side of the main body on one side of the suction pipe; the clamping mechanism includes a mounting shell with an axial opening on its lower surface; the left end of the mounting shell is fixedly connected to the side wall of the main body; a servo motor is fixedly connected to the right end of the mounting shell; a threaded rod is provided inside the mounting shell and is rotatably connected to the mounting shell; the output end of the servo motor extends into the mounting shell and is connected to the threaded rod; the servo motor can drive the threaded rod to rotate; a threaded sleeve is threadedly connected to the threaded rod; the front and rear side walls of the threaded sleeve slide in contact with the front and rear inner walls of the mounting shell; a hydraulic cylinder is fixedly connected to the bottom of the threaded sleeve; the upper end of the hydraulic cylinder extends into the mounting shell from the axial opening on the lower surface of the mounting shell; the output end of the hydraulic cylinder faces downwards; and a mounting plate is fixedly connected to the output end of the hydraulic cylinder.

The rotating seats at the left end of the two hinge rods are slidably connected to the left pressure rod, and the rotating seats at the right end of the two hinge rods are slidably connected to the right pressure rod. That is, the left and right pressure rods are provided with axial grooves on the side facing the hinge rods, and each rotating seat is placed in the corresponding groove, allowing the rotating seat to slide within the groove.

[0009] Both ends of the left pressure rod are connected to electric push rods, and the other ends of the two electric push rods are fixedly connected to the right pressure rod. That is, the fixed end of the electric push rod is fixed to the left pressure rod, and the extended end of the electric push rod is fixed to the right pressure rod. The operation of the electric push rod can change the distance between the left and right pressure rods.

[0010] It also includes two slidingly connected first pressure plates and second pressure plates. The left ends of the two first pressure plates are fixed to the front and rear ends of the left pressure rod. The right ends of the two second pressure plates facing the electric push rod are each fixed with a connecting block. The two connecting blocks are respectively fixed to the extended end of the electric push rod. The right ends of the two second pressure plates are connected to the front and rear ends of the right pressure rod.

[0011] The advantages of this invention are: by setting a pressing mechanism, the absorbent pad can be pressed after the filter cloth and absorbent pad are laid to prevent gas leakage. At the same time, it avoids the need for workers to constantly use steel pipes to press the absorbent pad, reducing the workload of workers, improving construction efficiency, and enhancing the practicality of the device.

[0018] Its features include: a clamping mechanism 7, which is located on the right side of the main body on one side of the suction pipe 5. The clamping mechanism 7 includes a mounting shell 70 with an axial opening on its lower surface. The left end of the mounting shell 70 is fixedly connected to the side wall of the main body 1, and the right end of the mounting shell 70 is fixedly connected to a servo motor 71. A threaded rod 72 is provided inside the mounting shell and is rotatably connected to the mounting shell. The output end of the servo motor extends into the mounting shell and is connected to the threaded rod. The servo motor can drive the threaded rod to rotate. A threaded sleeve 73 is threadedly connected to the threaded rod 72. The front and rear side walls of the threaded sleeve slide in contact with the front and rear inner walls of the mounting shell. A hydraulic cylinder 74 is fixedly connected to the bottom of the threaded sleeve 73.
