Description

Technical Field

[0001] The utility model belongs to the technical field of steel wire rope tensile strength testing, and in particular relates to a protective structure for steel wire rope tensile strength testing equipment of a cross-line beam hoisting machine. Background Art

[0002] A beam hoist is a special lifting equipment used in bridge construction. It is mainly used to lift prefabricated bridge components, such as box beams and T-beams. Therefore, the wire rope equipped with the beam hoist must have a larger diameter than ordinary wire ropes to withstand greater tension. Due to the large diameter of the wire rope, a longer style needs to be selected during the tensile strength test. Due to the long style of the wire rope, considering the space limitations of the vertical tensile testing machine, only a horizontal tensile testing machine can be used. Horizontal tensile testing machines are usually equipped with protective covers to block the high-speed flying fragments generated by the breakage of the wire rope when it is stretched to the limit.

[0003] At present, the existing horizontal tensile testing machines are large in size and long in shape. Correspondingly, the protective covers they use are usually one-piece, which are also large in size and long in shape, and are heavy overall. This makes it extremely inconvenient to disassemble and assemble this type of protective cover, and further results in the inability to effectively reduce the weight of the testing machine when it is moved, resulting in greater movement resistance and increased difficulty in moving.

[0004] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem in the above-mentioned prior art that the protective cover for the horizontal tensile testing machine is an integrated type, which is inconvenient to disassemble and assemble, and thus leads to the inability to effectively reduce the weight of the testing machine when it is moved, making it difficult to move, and to provide a protective structure for the tensile strength testing equipment of the wire rope of the cross-line beam lifting machine.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A protective structure for a tensile strength test equipment of a steel wire rope of a cross-line beam hoisting machine, comprising: a horizontal machine platform, a connecting rod and a protective cover, wherein a supporting arm protrudes horizontally outward from one side of the horizontal machine platform; the connecting rods are arranged at intervals on one side of the machine platform, and the length direction of the connecting rods is consistent with the length direction of the horizontal machine platform, so that the supporting arm supports the connecting rod, and one end of the connecting rod is bent toward the horizontal machine platform and hinged to the horizontal machine platform, and the height of the connecting rod is adjusted by swinging the connecting rod up and down; the protective cover is composed of a plurality of U-shaped cover plates connected in series by the connecting rods, and the U-shaped openings of the plurality of U-shaped cover plates are all facing downward to cover the top of the horizontal machine platform along the length direction, and two adjacent U-shaped cover plates are connected by a connecting arm.

[0008] In the protective structure for the tensile strength testing equipment of the steel wire rope of the cross-line beam hoisting machine as described above, preferably, the bottom of the horizontal platform is provided with supporting legs.

[0009] Preferably, the supporting arms are provided in plurality, and the plurality of supporting arms are spaced apart along the length direction of the connecting rod;

[0010] The supporting arm corresponds to the abutting position of two adjacent U-shaped cover plates.

[0011] Preferably, one end of the U-shaped cover plate is sleeved on the outside of the connecting rod, and the other end of the U-shaped cover plate is placed on the top edge of the horizontal machine.

[0012] Preferably, the U-shaped cover plate is sleeved on the side of one end of the connecting rod and is provided with a notch, so that a groove adapted to the top of the supporting arm is formed between two adjacent U-shaped cover plates.

[0013] Preferably, a protrusion is provided on the outer side of one end of the U-shaped cover plate placed on the top of the horizontal machine;

[0014] The connecting arm is laterally arranged between two adjacent protrusions.

[0018] Beneficial effects: The utility model is mainly used for horizontal tensile testing machines. Compared with traditional integrated protective covers, it is easier to disassemble and assemble. Based on this condition, when moving the testing machine, its own gravity can be effectively reduced to reduce moving resistance and reduce the difficulty of movement, thereby facilitating the preparation work before transporting the testing machine, and effectively solving the negative effects caused by the traditional integrated protective cover being large in size, long in shape and heavy overall.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0030] Embodiment: This embodiment aims to provide a protective structure for a cross-line beam lifting machine wire rope tensile strength test equipment, the main function of which is that the protective cover can be disassembled and assembled in sections, thereby effectively reducing the gravity of the testing machine, reducing its movement resistance, and reducing its movement difficulty.

[0031] Reference Figure 1 、 Figure 3 and Figure 6 , including: a horizontal machine 1, a connecting rod 3 and a protective cover. A plurality of legs 5 are fixed to the bottom of the horizontal machine 1, and the horizontal machine 1 is stably supported by the supporting legs 5. A plurality of supporting arms 2 protrude horizontally outward from the left side of the horizontal machine 1. The plurality of supporting arms 2 are spaced apart along the length direction of the horizontal machine 1. The connecting rod 3 is spaced apart on the left side of the machine. The length direction of the connecting rod 3 is consistent with the length direction of the horizontal machine 1, so that the connecting rod 3 is placed on the top of the supporting arm 2 and supported by the plurality of supporting arms 2. The rear end of the connecting rod 3 is bent toward the horizontal machine 1 and is hinged to the left side of the horizontal machine 1, so that the height of the connecting rod 3 can be adjusted by swinging the connecting rod 3 up and down. The purpose is to lift the connecting rod 3 and facilitate the sleeve of one end of the protective cover on the outside of the connecting rod 3.

[0032] Reference Figure 1 、 Figure 3 、 Figure 4 and Figure 6 The protective cover is composed of multiple U-shaped cover plates 4 connected in series by connecting rods 3, and the U-shaped mouths of the multiple U-shaped cover plates 4 are all facing downward to cover the top of the horizontal machine 1 along the length direction, and the two adjacent U-shaped cover plates 4 are connected by connecting arms. Specifically, the left end of the U-shaped cover plate 4 is slidably sleeved on the outside of the connecting rod 3, and the right end of the U-shaped cover plate 4 is placed on the top edge of the horizontal machine 1, and the supporting arm 2 corresponds to the abutment of the two adjacent U-shaped cover plates 4. A notch 6 is provided on the side of the left end of the U-shaped cover plate 4 to form a groove that is compatible with the top of the supporting arm 2 between the two adjacent U-shaped cover plates 4. The groove is provided to make the supporting arm 2 directly contact with the connecting rod 3, and then make the supporting arm 2 directly support the connecting rod 3, so as to avoid contact between the supporting arm 2 and the U-shaped cover plate 4 to hinder the U-shaped cover plate 4 from rotating to perform the cover-lifting action.

[0033] Reference Figure 1 、 Figure 2 and Figure 5, the U-shaped cover 4 is placed on the top of the horizontal machine 1, and a protrusion 7 is provided on the outside of the right end. The connecting arm is transversely arranged between the two adjacent protrusions 7. The protrusion 7 is provided to create a gap between the connecting arm and the right end of the U-shaped cover 4 to provide the staff with an operating space for manually adjusting the connecting arm. The connecting arm includes: a guide column 8, a screw 9 and a screw sleeve 10. One end of the guide column 8 is welded and fixed to one of the two adjacent protrusions 7, and the other protrusion 7 is welded and fixed to the end of the screw 9. One end of the screw sleeve 10 is slidably sleeved on the outside of the guide column 8, and the other end of the screw sleeve 10 is The end is threadedly sleeved on the outside of the screw 9 by rotating, and the two adjacent U-shaped cover plates 4 can be connected as one by sleeve 10 and screw 9. The guide column 8 is sleeved on one end of the sleeve 10 and is provided with an anti-slip plate 11. The anti-slip plate 11 prevents the sleeve 10 from separating from the guide column 8. At the same time, it is also for tightening the two adjacent U-shaped cover plates 4 by sleeve 10 and screw 9. After all the U-shaped cover plates 4 are assembled on the horizontal machine 1, the staff can lift the protective cover upwards through the connecting arm so that the staff can fix the wire rope to be tensile tested into the horizontal machine 1.

[0034] In actual use, first lift the connecting rod 3 upward to temporarily separate it from the support of the supporting arm 2, and then connect the U-shaped cover plates 4 in series on the connecting rod 3 one by one. During this period, the two adjacent U-shaped cover plates 4 are connected into one through the connecting arm, and ensure that the two adjacent U-shaped cover plates 4 are tightly attached. Finally, after all the U-shaped cover plates 4 are connected in series, lower the connecting rod 3. While the supporting arm 2 supports the connecting rod 3 again, it also disperses part of the gravity of the U-shaped cover plates 4. It should be noted that the purpose of hinged connection between the connecting rod 3 and the horizontal machine 1 is to limit the lateral displacement of the connecting rod 3. During the tensile test, the protective cover is lifted up by the connecting arm and the wire rope is fixed in the horizontal machine 1.

[0035] The protective structure provided in this embodiment is mainly used for horizontal tensile testing machines. Compared with traditional integrated protective covers, it is easier to disassemble and assemble. Based on this condition, when moving the testing machine, its own gravity can be effectively reduced to reduce the movement resistance and the difficulty of movement, thereby facilitating the preparation work before transporting the testing machine, and effectively solving the negative effects caused by the traditional integrated protective cover being large in size, long in shape, and heavy overall.

[0036] It will be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
