Description

Technical Field

[0001] This utility model relates to the field of cement preparation, specifically a proportioning device for preparing cement for high-speed rail. Background Technology

[0002] In the construction of high-speed rail infrastructure, cement is a key building material, and the accuracy of its proportion with sand and gravel directly affects the load-bearing capacity and durability of high-speed rail tracks. As the requirements for engineering quality in high-speed rail construction continue to increase, the shortcomings of traditional cement preparation and proportioning methods in terms of precision control and automation have gradually become apparent.

[0003] When preparing cement for ballastless track of high-speed railways, if the ratio of cement to sand and gravel deviates from the design standard, it will lead to insufficient concrete strength or cracking, which will directly affect the safety and stability of high-speed railway operation. Existing equipment has a low degree of automation, and the traditional proportioning process relies on manual operation of feeding, metering and mixing, which cannot realize automatic weighing and proportioning of materials. In large-scale high-speed railway construction, not only does it consume a lot of manpower, but it is also easy to cause proportioning errors due to human error, which will delay the construction progress. Therefore, it is necessary to design a proportioning equipment for cement preparation for high-speed railways to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a proportioning device for preparing cement specifically for high-speed rail, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a proportioning device for preparing cement for high-speed rail, comprising a protective box and a weighing box. The protective box is provided with a support assembly for driving the protective box to rise and fall. Two feed hoppers are installed on the top surface of the protective box. A baffle for blocking the discharge port of the feed hopper is provided on the top of the inner side of the protective box. A drive assembly for driving the baffle to move laterally is installed on the inner side of the protective box. The surface of the baffle is provided with perforations.

[0006] The weighing box is located inside the protective box. A weighing device for supporting the weighing box is installed at the bottom of the weighing box. A ramp is installed inside the weighing box. A discharge component that blocks the side of the weighing box is provided on one side of the weighing box.

[0007] Preferably, the support assembly includes two connecting plates, which are respectively installed on the front and rear sides of the protective box, and a hydraulic push rod is fixedly installed on the bottom surface of the connecting plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This high-speed rail-specific cement preparation proportioning equipment, when the switch of the first electric push rod is turned on, can drive the baffle moving rod, thereby changing the position of the perforation. When the perforation is facing the discharge port of the feed hopper, the material in the feed hopper will fall through the perforation into the weighing box. Through the cooperation of the weighing equipment and the controller, the two materials are automatically proportioned, completing the automatic proportioning work. It has a high degree of automation, high proportioning efficiency and can save manpower.

[0014] 2.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides a proportioning device for preparing cement for high-speed rail, including a protective box 1 and a weighing box 9. A support component for lifting the protective box 1 is provided on the outside of the protective box 1. Two feed hoppers 4 are installed on the top surface of the protective box 1. A baffle 6 for blocking the discharge port of the feed hopper 4 is provided on the top of the inner side of the protective box 1. A drive component for moving the baffle 6 laterally is installed on the inner side of the protective box 1. A perforation 7 is provided on the surface of the baffle 6.

[0022] The weighing box 9 is located inside the protective box 1. A weighing device 8 for supporting the weighing box 9 is installed at the bottom of the weighing box 9. A ramp 10 is installed inside the weighing box 9. A discharge component that blocks the side of the weighing box 9 is provided on one side of the weighing box 9.

[0023] Specifically, the controller works in conjunction with the weighing device 8 and the first electric push rod 5 to complete the proportioning of raw materials in the two feed hoppers 4 by changing the lateral position of the baffle 6. It has a high degree of automation, efficient proportioning and can save manpower.

[0024] The support assembly includes two connecting plates 2, which are respectively installed on the front and rear sides of the protective box 1. A hydraulic push rod 3 is fixedly installed on the bottom surface of the connecting plate 2. When the switch of the hydraulic push rod 3 is turned on, the connecting plate 2 and the protective box 1 can be raised and lowered.

[0025] The drive assembly includes a first electric push rod 5. One end of the first electric push rod 5 is fixedly installed inside the protective box 1. The output end of the first electric push rod 5 is fixed to the bottom surface of the baffle 6 through a fixing plate. When the switch of the first electric push rod 5 is turned on, the baffle 6 can be moved laterally, thereby changing the position of the perforation 7.

[0026] Among them, the top of the slope plate 10 is provided with an inclined surface, which is used to guide the raw material away from the weighing box 9.

[0027] The discharge assembly includes a mounting groove 11, inside which a second electric push rod 12 is installed. A blocking plate 13 is fixedly installed at the output end of the second electric push rod 12. The blocking plate 13 contacts the side of the weighing box 9, and the height of the blocking plate 13 is appropriately matched with the height of the weighing box 9. When the switch of the second electric push rod 12 is turned on, the blocking plate 13 is moved away from the weighing box 9, so that the discharge position of the weighing box 9 is not blocked. The material that has been proportioned and located on the top surface of the slope plate 10 can slide out along the slope of the slope plate 10, making it convenient to transport the proportioned material away.

[0028] Working Principle: This utility model is a proportioning device for preparing cement specifically for high-speed rail. During use, cement and sand / gravel are placed in two feeding hoppers 4 respectively. Turning on the switch of the first electric push rod 5 moves the baffle 6, thereby changing the position of the perforation 7. When the perforation 7 faces the discharge port of the feeding hopper 4, the material in the feeding hopper 4 will pass through the perforation 7 and fall into the weighing box 9. The protective box 1 covering the weighing box 9 reduces the amount of dust emitted during the proportioning process. The weighing device 8 weighs the net weight of the material in the weighing box 9 in real time and transmits the data to the controller in real time. When the material in one feeding hopper 4 reaches the target weight... After measurement, the controller controls the first electric push rod 5 to open, thereby driving the perforation 7 to move to face the discharge port of the other feed hopper 4. At this time, another material will enter the inside of the weighing box 9. The controller can subtract the target weight of the first material from the weighing data of the weighing equipment 8 to obtain the weight of the second material. After the second material reaches the target weight, the controller controls the first electric push rod 5 to open, so that the perforation 7 faces the middle of the protective box 1. At this time, both feed hoppers 4 stop discharging material, thus completing the quantitative proportioning of cement used in high-speed rail. It has a high degree of automation, high efficiency in proportioning and can save manpower.

[0029] After the proportioning is completed, the hydraulic push rod 3 is controlled to drive the protective box 1 to rise as a whole, so that the weighing box 9 is separated from the inner cavity of the protective box 1. At this time, the switch of the second electric push rod 12 is turned on, which drives the blocking plate 13 away from the weighing box 9, so that the discharge position of the weighing box 9 is not blocked. The material that has been proportioned and located on the top surface of the slope plate 10 can slide out along the slope of the slope plate 10, which facilitates the transportation of the proportioned material away, so as to carry out subsequent preparation work.
