Description

Technical Field

[0001] This utility model relates to the technical field of rebar testing equipment, and in particular to a weight deviation testing device. Background Technology

[0002] The construction industry is constantly progressing and developing. To ensure construction quality, management personnel need to effectively supervise and manage the work to ensure that the performance of building materials meets the specified requirements. Among these materials, steel bars are one of the main raw materials for construction. When testing steel bars, the weight deviation is one of the important technical indicators. The existing steel bar testing process, according to the specifications, requires cutting both ends of the steel bars flat with a cutting machine, then measuring the length of each sample with a steel ruler to an accuracy of 1 mm, manually entering the measurements into the computer, and finally weighing the steel bars with a balance and manually entering the weight into the computer. This method is inefficient and has low accuracy. The length measurement requires manual reading, which introduces a large margin of error. Utility Model Content

[0003] The purpose of this invention is to provide a weight deviation detection device. By placing the specimen on a specimen rack and then using the detection device to detect the weight deviation of the specimen on the specimen rack, the workload of manual operation is greatly reduced and the detection efficiency is improved.

[0004] To achieve the purpose of this utility model, a weight deviation detection device is provided, comprising: a base, two support columns fixedly connected to both sides of the base plate, a top plate fixedly connected to the top of the support columns, two specimen rack guide rails provided on the base plate, a specimen rack slidably installed between the specimen rack guide rails, several placement positions provided on the specimen rack for placing specimens, and a detection device provided on the side end of the support columns, the two ends of the detection device being vertically slidably connected to the side ends of the two support columns via slide rails.

[0005] As a preferred embodiment of this utility model, the specimen rack includes a base plate, with a traveling wheel installed at the bottom end of the base plate. Two guide pulleys are installed on each of the two sides of the base plate. The outer edges of the guide pulleys on both sides are fitted against the inner wall of the guide rail of the specimen rack. Two columns are fixedly connected to the surface of the base plate. A connecting plate is fixedly connected to the top of the columns. Several specimen support plates are fixedly connected to the front side wall of the columns. The specimen support plates are evenly spaced from top to bottom, and the specimen support plates at the same height on the two columns are mutually adapted.

[0006] As a preferred embodiment of this utility model, the height of the top plate of the connecting plate is set lower than the height of the bottom plate of the top plate.

[0007] As a preferred technical solution of this utility model, the top of the specimen support plate is provided with a specimen placement groove, and the specimen placement groove is a V-shaped groove structure.

[0008] As a preferred technical solution of this utility model, one end of each of the two specimen rack guide rails is provided with an open guide rail, and the open guide rail is provided with an outwardly opening arc-shaped structure.

[0009] As a preferred technical solution of this utility model, a limiting baffle is provided at the end of the two support columns away from the opening guide rail, and the two ends of the limiting baffle are respectively connected to the bottom of the side ends of the two support columns.

[0010] As a preferred technical solution of this utility model, the detection device includes a housing, the two ends of which are vertically slidably connected between the two support columns via slide rails. The housing is driven by a first motor. A sliding crossbar is fixedly connected to the end of the housing near the specimen holder. Sliding members are sleeved at both ends of the sliding crossbar. The sliding members slide laterally on the sliding crossbar. The sliding members are driven by a second motor. A detection pen is fixedly connected to the side end of the sliding member. The detection pen and the specimen support plate are arranged in the same direction.

[0011] As a preferred embodiment of this utility model, the side end of the detection pen has a U-shaped opening, the opening direction of the U-shaped opening is set to face the test piece, and the size of the U-shaped opening is set to be larger than the size of the test piece.

[0012] As a preferred embodiment of this utility model, a specimen support groove is provided on the inner wall of the bottom end of the U-shaped opening, a weighing sensor is provided at the bottom of the specimen support groove, and an infrared measurement sensor is provided on the outer side of the U-shaped opening.

[0013] As a preferred embodiment of this invention, a barcode scanner is provided at the bottom of the detection pen.

[0014] Compared with the prior art, the present invention provides a weight deviation detection device, which has the following beneficial effects:

[0015] In use, the testing personnel place the test specimens in the specimen support plate of the test specimen rack according to batch order. If the test specimen has a code containing specimen information, the code is aligned with the blank position on the side of the test specimen. The test specimen rack is then pushed along the guide rail to the bottom of the top plate, and the testing device begins to detect the weight deviation of the test specimen. The housing is slid to the same height as the test specimen by the first motor. The initial position of the detection pen is on the outside of the test specimen. The detection pens on both sides are slid inward by the second motor, fitting the test specimen into the U-shaped opening. During the sliding process, the barcode scanner can scan the code to obtain the test specimen information and upload it to the control system. The specimen information includes the type and specifications of the reinforcing steel. If there is no label, it can be manually entered by the inspector. On the other hand, an infrared measuring sensor can detect the two ends and the middle of the specimen, obtaining the coordinate information of these positions. The actual length of the specimen is calculated from this coordinate information. The shell slides upwards driven by a first motor, and the specimen support groove completely lifts the specimen, causing it to detach from the specimen placement groove. A weighing sensor at the bottom of the support groove directly weighs the actual weight of the specimen. The shell then falls back into the specimen placement groove, and the measuring pen slides outwards back to its initial position. The control system calculates the theoretical weight and allowable deviation of the specimen using the actual length and specimen information. The actual weight is compared to the theoretical weight to determine the actual deviation. If the actual deviation is within the allowable deviation, the specimen's weight deviation detection data is recorded as qualified; if it exceeds the allowable deviation, the specimen's weight deviation detection data is recorded as unqualified.
