Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete sampling, and in particular to a concrete production testing powder sampling device. Background Technology
[0002] In the concrete production process, the quality and performance of the powder have a significant impact on the strength and durability of the concrete. Therefore, sampling the concrete powder is crucial to ensure its quality after storage. When sampling concrete powder, multiple samples need to be taken from different locations within the powder pile to obtain more representative samples.
[0003] Chinese Patent Publication No. CN210923181U discloses a concrete powder sampling device, which includes a base with an adjusting mechanism vertically fixed on its upper surface. A sampling mechanism is slidably connected to the adjusting mechanism. The adjusting mechanism includes a support column vertically fixed to the upper surface of the base, a transmission component inside the support column, and a support block slidably connected to the transmission component. A groove is formed on the support column opposite to the support block, with the length direction of the groove being the same as the height direction of the support column. One end of the support block extends from the groove and is fixedly connected to a support plate. The adjusting mechanism and the sampling mechanism are fixedly connected through the support plate. The sampling mechanism includes a vertically arranged sampling cylinder, a sampling component, and a collection chamber connected to the sampling cylinder through a feeding pipe. The sampling cylinder is located at the bottom end of the support plate and fixedly connected to it. The sampling component is disposed inside the sampling cylinder. This utility model has the advantages of avoiding direct manual sampling, adapting to different sampling environments, and flexibly adjusting the sampling height.
[0004] However, this device has the following drawbacks: While it avoids direct manual sampling, the sampling mechanism is mounted on the base. When sampling powder materials in large storage silos, the device's large size and reliance on the base for movement make it difficult to move to the center of the silo for sampling. Sampling is limited to the periphery, resulting in incomplete sampling. To address these drawbacks, we propose a concrete production and testing powder sampling device. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concrete production testing powder sampling device.
[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a concrete production testing powder sampling device, comprising:
[0007] The movable hanging rail includes two transverse rails, a longitudinal rail disposed between the two transverse rails, a first trolley running mechanism fixedly installed at both ends of the longitudinal rail, and a second trolley running mechanism slidably installed on the surface of the longitudinal rail, wherein the two first trolley running mechanisms are slidably connected to the inner walls of the two transverse rails respectively.
[0008] The sampling structure includes a mounting plate, a material taking component fixedly mounted below the mounting plate, and a material storage component disposed on the surface of the material taking component.
[0009] The material handling assembly includes a material handling cylinder fixedly installed at the lower end of the mounting plate, a conveying auger rotatably installed on the inner wall of the material handling cylinder, and a first motor fixedly installed at the upper end of the mounting plate to drive the conveying auger to rotate.
[0010] The hoisting structure comprises a traction assembly and a guide assembly;
[0011] The traction assembly includes a mounting plate fixedly mounted on the lower surface of the second trolley running mechanism, a take-up roller rotatably mounted on the lower surface of the mounting plate, a traction rope wound around the surface of the take-up roller, and a second motor fixedly mounted on the lower surface of the mounting plate that can drive the take-up roller to rotate.
[0012] Preferably, the guide assembly includes multiple telescopic rods fixedly installed on the lower surface of the mounting plate, and the other end of the multiple telescopic rods and the pull rope are fixedly connected to the upper surface of the mounting plate.
[0013] Preferably, the storage assembly includes a storage cylinder and a connecting cylinder fixedly installed on the surface of the receiving cylinder, and an assembly assembly is provided between the storage cylinder and the mounting plate.
[0014] Preferably, one end of the connecting cylinder is in communication with the interior of the material receiving cylinder.
[0015] Preferably, the assembly assembly includes a support rod fixedly installed on the surface of the storage cylinder, an assembly block fixedly installed on the upper surface of the support rod, and an assembly slot block fixedly installed on the lower surface of the mounting plate.
[0016] Preferably, the left side of the assembly block is provided with an assembly groove that is adapted to the assembly block, and the shape of the assembly block is set as T-shaped.
[0017] Preferably, the surface of the assembly slot is threaded with an assembly bolt, and the nut end of the assembly bolt extends into the interior of the assembly slot.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. By setting up a mobile hanging rail, a sampling structure, and a hoisting structure, the mobile hanging rail is installed above the storage silo. When sampling, the longitudinal rail and the second trolley running mechanism on the mobile hanging rail can first drive the sampling structure to move above the storage silo, thus allowing the sampling structure to move to any position above the storage silo. Then, the hoisting structure can be used to drive the sampling structure to descend, so that the conveying auger on the sampling structure can rotate to break open the powder and create holes, allowing the sampling cylinder to enter the depth of the powder pile along the holes for sampling. This facilitates sampling at any position in the storage silo, making the sampling location more comprehensive.
[0020] 2. By setting up a material taking component, the storage cylinder is installed on the mounting plate using the assembly structure. Then, the conveying auger is rotated to take samples. At this time, the conveying auger will push the powder along the material taking cylinder into the connecting cylinder and then into the storage cylinder, so that the sample can be stored. Afterwards, the assembly bolts can be loosened to remove the storage cylinder and collect the sample, which facilitates the retrieval of the sample. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] Please see Figure 1-4This utility model provides a technical solution: a concrete production testing powder sampling device, including: a mobile suspension rail, a sampling structure, and a hoisting structure.
[0029] See Figure 1 The mobile crane rail includes two transverse rails 1, a longitudinal rail 2 disposed between the two transverse rails 1, a first trolley running mechanism 3 fixedly installed at both ends of the longitudinal rail 2, and a second trolley running mechanism 4 slidably installed on the surface of the longitudinal rail 2. The two first trolley running mechanisms 3 are slidably connected to the inner walls of the two transverse rails 1 respectively. The first trolley running mechanism 3 and the second trolley running mechanism 4 are both existing technologies and have the same principle as the trolley running mechanism on the gantry crane, so they will not be described in detail. The mobile crane rail is installed above the storage bin. Driving the first trolley running mechanism 3 can drive the longitudinal rail 2 to slide along the inner wall of the transverse rail 1, and driving the second trolley running mechanism 4 can drive the second trolley running mechanism 4 to slide along the inner wall of the longitudinal rail 2.
[0030] See Figure 1 , Figure 3 and Figure 4 The sampling structure includes a mounting plate 5, a material picking component fixedly installed below the mounting plate 5, and a material storage component disposed on the surface of the material picking component.
[0031] See Figure 4 The material handling assembly includes a material handling cylinder 6 fixedly installed at the lower end of the mounting plate 5, a conveying auger 7 rotatably installed on the inner wall of the material handling cylinder 6, and a first motor 8 fixedly installed at the upper end of the mounting plate 5 to drive the conveying auger 7 to rotate. Driving the first motor 8 forward can drive the conveying auger 7 to rotate forward. When the conveying auger 7 rotates forward, the powder material at the bottom of the material handling cylinder 6 can be conveyed upward.
[0032] See Figure 1-2 The hoisting structure consists of a traction assembly and a guide assembly. The traction assembly includes a mounting plate 9 fixedly mounted on the lower surface of the second trolley running mechanism 4, a take-up roller 10 rotatably mounted on the lower surface of the mounting plate 9, a traction rope 11 wound around the surface of the take-up roller 10, and a second motor 12 fixedly mounted on the lower surface of the mounting plate 9 that can drive the take-up roller 10 to rotate. Driving the second motor 12 to rotate forward and reverse can drive the take-up roller 10 to rotate forward and reverse, thereby winding and unwinding the traction rope 11.
[0033] The guide assembly includes a multi-section telescopic rod 13 fixedly installed on the lower surface of the mounting plate 9, and the other end of the multi-section telescopic rod 13 and the pull rope 11 are fixedly connected to the upper surface of the mounting plate 5. When the pull rope 11 is extended, the pull rope 11 will be taut due to the gravity of the material picking assembly, and the multi-section telescopic rod 13 will extend and become longer, thereby preventing the material picking assembly from swinging.
[0034] During sampling, the longitudinal rail 2 on the moving hoist and the second trolley running mechanism 4 are used to drive the sampling structure to move above the storage bin, allowing the sampling structure to be moved to any position above the storage bin. Then, the hoisting structure is used to drive the sampling structure to descend and contact the powder. When the sampling cylinder 6 on the sampling structure contacts the powder, the conveying auger 7 is driven to reverse. The reversed conveying auger 7 can break the powder pile to form holes. Since the powder has low hardness, the reversed conveying auger 7 can easily break the powder, and the reversed conveying auger 7 can prevent the powder from entering the sampling cylinder 6.
[0035] See Figure 3 The material storage assembly includes a material storage cylinder 14 and a connecting cylinder 15 fixedly installed on the surface of the material taking cylinder 6. One end of the connecting cylinder 15 is in communication with the interior of the material taking cylinder 6.
[0036] An assembly assembly is provided between the storage cylinder 14 and the mounting plate 5. The assembly assembly includes a support rod 16 fixedly installed on the surface of the storage cylinder 14, an assembly block 17 fixedly installed on the upper surface of the support rod 16, and an assembly groove block 18 fixedly installed on the lower surface of the mounting plate 5. An assembly groove 19 adapted to the assembly block 17 is opened on the left side of the assembly groove block 18, and the shape of the assembly block 17 is set as T-shaped. An assembly bolt 20 is threadedly connected to the surface of the assembly groove block 18, and the nut end of the assembly bolt 20 extends into the interior of the assembly groove 19.
[0037] Insert the assembly block 17 into the assembly slot 19, and then tighten the assembly bolt 20. The assembly bolt 20 can be used to press against the assembly block 17, so that the storage cylinder 14 and the mounting plate 5 can be assembled into one piece. At this time, the storage cylinder 14 is directly below the connecting cylinder 15.
[0038] After the storage cylinder 14 is installed on the mounting plate 5 using the assembly structure, the conveying auger 7 is rotated to take samples. At this time, the conveying auger 7 will push the powder along the taking cylinder 6 into the connecting cylinder 15 and then into the storage cylinder 14, so that the sample can be stored. Afterwards, the assembly bolt 20 can be loosened to take out the storage cylinder 14 and collect the sample, which makes it convenient to take the sample.
[0039] The sampling structure can be moved to any position above the storage silo by using the mobile hoisting rail. In conjunction with the reversing conveyor auger 7, the sampling cylinder 6 can gradually break through the powder and enter the depth of the powder pile. Once it enters the depth of the powder pile, the conveyor auger 7 can be driven to rotate forward to take samples, which facilitates sampling at any position in the storage silo and makes the sampling position more comprehensive.
[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of this utility model should be included within the scope of protection of this utility model.
