Description

Technical Field

[0001] The utility model belongs to the technical field of rubber pipeline detection, and particularly relates to a tensile strength detector for rubber pipeline production. Background Art

[0002] After years of development, the rubber tube industry in China has played an indispensable supporting role in the national economy. Especially with the improvement of China's mechanization level and the application of new materials, the rubber tube industry has continuously penetrated into related fields, expanding the application scope and fields of rubber tubes. The products are widely used in coal, metallurgy, cement, mines, petroleum, automobiles, textiles, light industry, construction, agriculture, aviation and other fields.

[0003] After the rubber tube is manufactured, it needs to be subjected to tensile strength detection to check whether the rubber tube meets the quality requirements. The connection between the current tensile strength detection device and the rubber tube is not firm. When the rubber tube is stressed, the connection is prone to looseness or even detachment, affecting the detection results of the rubber tube. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a tensile strength detector for rubber pipeline production.

[0005] The utility model is realized as follows: A tensile strength detector for rubber pipeline production includes a base. Vertically and symmetrically fixed on the upper end of the base are columns. Horizontally fixed on the upper ends of the columns is a cross bar. Horizontally arranged above the base is a lifting plate. The columns pass through through holes opened on the lifting plate. Vertically fixed between the lifting plate and the base is a hydraulic rod mechanism. The lifting plate makes a stable lifting movement under the action of the hydraulic rod mechanism. A first pulling member is arranged on the upper end of the base, and a second pulling member is arranged on the lower end of the lifting plate. The rubber tube is clamped by the first pulling member and the second pulling member. The first pulling member includes a first clamping block and a second clamping block. One end of the rubber tube is clamped by the first clamping block and the second clamping block. The first clamping block is fixedly arranged on the base as a fixed end. Horizontally opened on the upper end of the base and near the first clamping block are a first through groove and a second through groove that are connected. The width of the second through groove is greater than that of the first through groove. A first clamping block is arranged in the second through groove. The width of the first clamping block is greater than that of the first through groove, preventing the first clamping block from detaching from the first through groove, thereby ensuring the reliable connection between the second clamping block and the base. The lower end of the second clamping block passes through the first through groove and is fixedly connected to the first clamping block. The second clamping block serves as a moving end and moves along the first through groove.

[0006] One end of the first clamping block in contact with the second clamping block is fixedly provided with first clamping teeth that are meshed with each other in a staggered manner. The end of the rubber tube is clamped by the first clamping teeth, ensuring a reliable connection between the first clamping block, the second clamping block and the rubber tube. A plurality of first annular grooves are horizontally formed on the outer wall of the first clamping block, and a plurality of second annular grooves are horizontally formed on the outer wall of the second clamping block. The positions of the first annular grooves and the second annular grooves correspond to each other and are communicated with each other.

[0007] The second pulling member includes a third clamping block and a fourth clamping block. The other end of the rubber tube is clamped by the third clamping block and the fourth clamping block. The third clamping block is fixedly arranged on the lifting plate as a fixed end. A third through groove and a fourth through groove that are communicated with each other are horizontally formed at the lower end of the lifting plate and near the third clamping block. The width of the fourth through groove is greater than the width of the third through groove. A second clamping block is arranged in the fourth through groove. The width of the second clamping block is greater than the width of the third through groove, preventing the second clamping block from disengaging from the third through groove, thereby ensuring a reliable connection between the fourth clamping block and the lifting plate. The upper end of the fourth clamping block passes through the third through groove and is fixedly connected to the second clamping block. The fourth clamping block serves as a movable end and moves along the third through groove.

[0008] One end of the third clamping block in contact with the fourth clamping block is fixedly provided with second clamping teeth that are meshed with each other in a staggered manner. The end of the rubber tube is clamped by the second clamping teeth, ensuring a reliable connection between the third clamping block, the fourth clamping block and the rubber tube. A plurality of third annular grooves are horizontally formed on the outer wall of the third clamping block, and a plurality of fourth annular grooves are horizontally formed on the outer wall of the fourth clamping block. The positions of the third annular grooves and the fourth annular grooves correspond to each other and are communicated with each other. Pipe clamps are arranged in the first annular grooves and the second annular grooves, and in the third annular grooves and the fourth annular grooves. The pipe clamps are sleeved on the first annular grooves and the second annular grooves, enabling the first clamping block and the second clamping block to tightly, firmly and reliably clamp one end of the rubber tube. The pipe clamps are sleeved on the third annular grooves and the fourth annular grooves, enabling the third clamping block and the fourth clamping block to tightly, firmly and reliably clamp the other end of the rubber tube.

[0009] Preferably, the pipe clamp includes a first clamp body and a second clamp body. One end of the first clamp body and the second clamp body is hinged together. A first threaded hole is formed at the other end of the first clamp body, and a second threaded hole is formed at the other end of the second clamp body. The positions of the first threaded hole and the second threaded hole correspond to each other and have the same aperture. A bolt is arranged through the first threaded hole and the second threaded hole, and a nut is tightly sleeved on the bolt. The nut is tightened to ensure a tight and reliable restraint of the pipe clamp between the first clamping block and the second clamping block, and between the third clamping block and the fourth clamping block.

[0010] Preferably, a display screen is fixedly arranged on the cross bar, a tension sensor is arranged between the first clamping member and the second clamping member, the first clamping block and the third clamping block are fixedly connected to both ends of the tension sensor, and the tension sensor is electrically connected to the display screen. As the hydraulic rod mechanism drives the lifting plate to rise, the rubber tube is stretched, and the tension sensor immediately transmits the value to the display screen for people to directly observe.

[0011] The beneficial effects of the present utility model are as follows: The structure of the present utility model is novel. The rubber tube is clamped by the first pulling member and the second pulling member, and the end of the rubber tube is bitten by the first clamping teeth that are meshed with each other in the first pulling member, ensuring a reliable connection between the first pulling member and the rubber tube. The pipe clamp is sleeved in the first annular groove and the second annular groove on the first pulling member, enabling the first pulling member to tightly and firmly clamp one end of the rubber tube, and the connection part is not easy to loosen, ensuring the detection result of the rubber tube.
