[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.
[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0023] like Figures 1 to 3 As shown, a cable double-bearing and double-guiding adjustment tool for tunnel construction includes an adjusting arm 1, a connecting arm 2, a first wire hook 3 and a second wire hook 4. The adjusting arm 1 is straight, the connecting arm 2 is parallel to the adjusting arm 1, and is connected to the adjusting arm 1 along the length direction of the adjusting arm 1; the first wire hook 3 is provided at the front end of the adjusting arm 1, and the second wire hook 4 is provided at the front end of the connecting arm 2. The first wire hook 3 is located in front of the second wire hook 4, and the first wire hook 3 and the second wire hook 4 are spaced apart from each other; the first wire hook 3 and the second wire hook 4 respectively include a bent hook portion 5 and an opening portion 7, and the inside of the bent hook portion 5 constitutes a bearing space 6 for bearing the cable.
[0024] The utility model discloses a cable double-support and double-guide adjustment tool for tunnel construction. In a subway vehicle section during tunnel construction, when adjusting the pull-out value of the cable and the cable guide height, an adjustment arm is used to hook the double cables into the bearing space 6 of the first wire hook 3 and the second wire hook 4 respectively. By lifting the adjustment arm, the connecting arm is driven so that the first wire hook 3 and the second wire hook 4 carry and guide the double cables, and the double cables can be adjusted into place synchronously at one time. The first wire hook and the second wire hook of the adjustment tool constitute a double support and double guide for the double cables, and the double cables can be adjusted into place synchronously at one time. The utility model has the characteristics of high precision, convenient construction, high efficiency, etc.
[0025] like Figure 1 As shown, the first and second wire hooks 3 and 4 have the same shape and size. The hook portion 5 is generally semicircular. The first and second wire hooks 3 and 4 are parallel to each other. The distance between the first and second wire hooks 3 and 4 is 40 mm, making them more suitable for simultaneous adjustment of two cables.
[0026] like Figure 1 As shown, the openings 7 of the first wire hook 3 and the second wire hook 4 are aligned downward, making it easier for the two cables to enter the carrying space 6 respectively and making the operation more convenient.
[0027] like Figure 2 As shown, the adjustment arm 1, first cable hook 3, connecting arm 2, and second cable hook 4 are made of an elongated alloy sheet with a width of 4 to 5 cm. Preferably, low-alloy, high-strength steel is used. This ensures that the adjustment arm 1, first cable hook 3, connecting arm 2, and second cable hook 4 have a certain width, preferably 4 to 5 cm, to protect the cables.
[0028] like Figure 1 As shown, the adjustment arm 1 is connected to the first wire hook 3 as an integral structure, and the connecting arm 2 is connected to the second wire hook 4 as an integral structure. The end of the connecting arm 2 is flush with the end of the adjustment arm 1, and the connecting arm 2 is welded to the adjustment arm 1. The overall structure is simple, easy to manufacture, strong and durable, and has low production costs.
[0029] like Figure 1 As shown, the lower portion of the adjustment arm 1 and / or connecting arm 2 is provided with a mounting hole 9 for connecting a U-shaped hanging ring 8. A U-shaped hanging ring is a U-shaped hardware fixture used on power lines, consisting of a hanging ring and a hanging plate connector at each end. The U-shaped hanging ring can be used to suspend or secure electrical components such as cables and wires. The U-shaped hanging ring 8 on the lower portion of the adjustment tool of this utility model facilitates portability. Its lower portion can be fixed to a cable, making it even more convenient to use.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
