[0028] Embodiment. This embodiment aims to provide a detection device for the verticality of the outrigger of a bridge erecting machine, and its main function is reflected in the more convenient disassembly and assembly of the total station, reducing the time consumed by the leveling preparation work of the total station.

[0029] As Figures 1-3 shown, it includes: a tripod, an outrigger, a pair of swing rods 4 and an elastic rope 7. The tripod includes: a triangular platform 1 and an outrigger. The outrigger is erected on one side of the bottom of the triangular platform 1, so that the upper end of the outrigger is hinged to one side of the bottom of the triangular platform 1. The length of the outrigger can be freely adjusted according to the working requirements, increasing the applicability of the detection device.

[0030] As Figure 4 shown, the outrigger includes: a U-shaped frame 8 and a sliding plate 9. The closed end of the U-shaped frame 8 is hinged to one side of the bottom end of the triangular platform 1, and a fastener is provided at the open end; the sliding plate 9 is located in the U-shaped space of the U-shaped frame 8 and slides along the length direction of the U-shaped space.

[0031] In a specific embodiment of the present application, the closed end, that is, the upper end of the U-shaped frame 8, is hinged to the middle of one side of the bottom of the triangular platform 1. The open end, that is, the lower end of the U-shaped frame 8, is provided with a fastener. The sliding plate 9 is located in the U-shaped space of the U-shaped frame 8 and freely slides in the U-shaped space along the length direction of the U-shaped frame 8. Thus, the length of the outrigger can be adjusted according to the working requirements, increasing the practicality of the work.

[0032] As Figure 1 shown, the fastener includes: a setscrew 11 and a limit ring 10. The limit ring 10 is sleeved on the open end of the U-shaped frame 8;

[0033] The setscrew 11 sequentially penetrates through the limit ring 10 and the U-shaped frame 8 from the side of the limit ring 10 and presses against the side of the sliding plate 9.

[0034] In a specific embodiment of the present application, the fastener includes: a limit ring 10 and a setscrew 11. The limit ring 10 is sleeved on the open end of the U-shaped frame 8. The head end of the setscrew 11 sequentially penetrates through the limit ring 10 and the column leg of the U-shaped frame 8 from the outside along the width direction of the sliding plate 9 and presses against the side wall of the sliding plate 9. Among them, the setscrew 11 is threadedly connected to the column leg of the U-shaped frame 8, so that by screwing the setscrew 11, its head end presses the sliding plate 9 tightly, and fixing through external parts can effectively increase the convenience of operation.

[0035] As Figure 1 shown, a foot pressure plate 12 vertically protrudes from the outer side of the bottom of the sliding plate 9. In a specific embodiment of the present application, by providing the foot pressure plate 12, it is convenient to insert the sliding plate 9 into the soft formation surface, thereby ensuring the stability of the tripod.

[0036] As Figure 3As shown, a slot 2 matching the total station base is provided in the center of the top of the tripod 1. Common total station bases are usually triangular in shape, and the total station base can be directly placed in this slot 2. Perforations 3 are provided on the two adjacent side walls of the tripod 1. Two rocker arms 4 correspond to the two perforations 3 and are horizontally arranged on the outside of the two adjacent side walls of the tripod 1. A triangular card plate 5 protrudes horizontally from the rocker arm 4 toward one side of the tripod 1, so that one corner of the card plate 5 passes through the perforation 3 and enters the slot 2. Correspondingly, a notch corresponding to the card plate 5 is also provided on the side of the total station base. The ends of the two rocker arms 4 that are away from each other are correspondingly hinged to the outside of the side wall of the tripod 1. The card plate 5 is driven in and out of the slot 2 by lateral swinging of the rocker arm 4. The total station can be quickly disassembled by detaching the card plate 5 from the slot 2. The insertion slot 2 is inserted into the notch on the base of the total station to achieve quick fixation of the total station. Finger rings 6 are welded to the side parts of the ends of the two pendulum rods 4 that are close to each other, so that a corner is formed between the outer ring surface of the finger ring 6 and the corresponding pendulum rod 4, and a corner is formed between the outer ring surface of the finger ring 6 and the corresponding pendulum rod 4. The elastic rope 7 is simultaneously hooped into the corner formed between the two finger rings 6 and the corresponding pendulum rod 4, and the two pendulum rods 4 are gathered together by the elastic rope 7. The elastic rope 7 is conveniently limited by the corner to prevent it from falling off easily. The two finger rings 6 are convenient for the staff to use the index finger and thumb to move the two pendulum rods 4 in opposite directions. During this period, the two pendulum rods 4 will stretch the elastic rope 7, and the elastic rope 7 can be used to quickly reset the two pendulum rods 4, thereby achieving quick installation of the base of the total station.

[0037] In this embodiment, the corners of the tripod 1 are arc-shaped, making its edges and corners smoother and safer to use. The ends of the two rocker arms 4 that are close to each other are bent and stretched toward each other to be attached to the center of the corners of the tripod 1. The purpose is to make the shape of the rocker arms 4 adapt to the corners of the tripod 1, making its structure more compact and more conducive to the staff's operation of the disassembly and assembly of the total station.

[0038] In actual use, first prop up the tripod on the ground and keep the tripod 1 level, then place the total station base in the slot 2 on the top of the tripod 1. Before that, the staff inserts the index finger and thumb into the two finger rings 6 to push the two swing rods 4 in opposite directions, thereby disengaging the card plate 5 from the slot 2. After the total station base is placed in the slot 2, the index finger and thumb are pulled out from the corresponding finger rings 6, and the two swing rods 4 are reset by the elastic rope 7, thereby allowing the card plate 5 to re-enter the slot 2 to be inserted into the reserved notch of the total station base, thereby fixing the total station. Finally, the staff can fine-tune the horizontality of the total station.

[0039] This embodiment abandons the fixing method of traditional verticality detectors, eliminating the need to align with fasteners when installing total stations and repeatedly tighten bolts when disassembling and assembling total stations, providing great convenience to workers and being extremely convenient to use. This indirectly reduces the time consumed in the leveling preparation work of total stations.

[0040] It can be understood that the above description is only exemplary, and the embodiments of the present application do not limit this.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, 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.
