DETAILED DESCRIPTION

[0025] To make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the protection scope of the present disclosure.

[0026] Please refer to Figures 1-6 A bridge surveying and drilling device, comprising: a frame 1, the frame 1 is provided with a first slide rod 11 and a second slide rod 12, the upper and lower ends of the first slide rod 11 and the second slide rod 12 are fixedly connected to the frame 1, the first slide rod 11 is located in the central region of the frame 1, a motor 5 is fixedly installed at the middle position of the side of the frame 1, the output shaft of the motor 5 is fixedly connected with a drive rod 8, a weight 6 is movably sleeved outside the first slide rod 11, a limiting plate 61 is fixedly connected to one side of the weight 6, the limiting plate 61 is movably sleeved on the second slide rod 12, a drill rod 4 is fixedly connected to the bottom of the frame 1, a third slide rod 3 is threadedly connected to the top of the frame 1, the third slide rod 3 is convenient for disassembly and assembly and equipment transportation, a support assembly 2 is movably sleeved outside the third slide rod 3, the support assembly 2 is used for supporting the equipment, so that the equipment does not need to be supported by a worker during work, and the weight 6 reciprocates in the vertical direction after the motor 5 drives the drive rod 8 to rotate.

[0027] Specifically, the motor 5 drives the drive rod 8 to rotate slowly, so as to push the limiting plate 61 and lift the weight 6, after the drive rod 8 is separated from the limiting plate 61, the weight 6 slides downward along the first slide rod 11 and impacts on the frame 1 under the action of gravity, the force generated by the falling of the weight 6 is applied to the ground through the drill rod 4, so that the drill rod 4 is inserted into the soil layer, and the purpose of drilling is achieved, the device has small size, is easy to use and carry, is simple to drive, and compared with manual drilling, the drilling speed is accelerated and the working strength is reduced.

[0028] Further, a vertical rod 81 is fixedly connected to the side of the drive rod 8, a roller 82 is movably sleeved outside the vertical rod 81, a bearing plate 7 is fixedly sleeved outside the first slide rod 11, and the bottom of the bearing plate 7 is fixedly connected to the frame 1.

[0029] Specifically, refer to Figure 3 When the motor 5 drives the driving rod 8 to rotate, the roller 82 contacts the limit plate 61 and pushes the limit plate 61, so that the weight 6 and the limit plate 61 move vertically upward along the first slide bar 11 and the second slide bar 12 respectively. At the same time, the roller 82 moves outward along the limit plate 61. When the end of the driving rod 8 on which the roller 82 is installed rotates to the highest point, the roller 82 disengages from the limit plate 61, causing the weight 6 to fall from the corresponding height and hit the load-bearing plate 7, so that the drill rod 4 achieves the purpose of drilling under the action of the weight 6 hitting the load-bearing plate 7 multiple times.

[0030] Furthermore, the drill rod 4 is threadedly connected to the first sliding rod 11 .

[0031] Specifically, refer to Figure 6 The drill rod 4 is connected by a threaded connection, which can adjust the depth of the drilled hole and is convenient for transportation after disassembly.

[0032] Furthermore, the support assembly 2 includes a sleeve 21, which is movably sleeved on the outside of the third slide rod 3. Three support rods 22 are arranged in an array on the side of the sleeve 21. The ends of the support rods 22 are rotatably set on the sleeve 21. The bottom of the support rod 22 is fixedly connected to a pad 23. The bottom of the pad 23 is provided with anti-slip grooves 231. The bottom of the pad 23 is fixedly connected to a drill bit 24, and the drill bit 24 is arranged coaxially with the support rod 22.

[0033] Specifically, refer to Figure 2 and Figure 4 The sliding sleeve 21 is sleeved on the third sliding rod 3. As the drill rod 4 is gradually inserted into the soil layer, the frame 1 drives the third sliding rod 3 to gradually descend. Under the limiting action of the sliding sleeve 21, the third sliding rod 3 can slide vertically downward, so that the drill rod 4 can drill vertically. When arranging the equipment, first disperse the three support rods 22, and step on the pad 23 to insert the drill bit 24 into the soil layer, which acts as a support frame for the equipment.

[0034] In this utility model, reference is made to Figures 1 to 6 First, according to the location of the hole to be drilled, spread out the three support rods 22, and step on the pad 23 to insert the drill bit 24 into the soil layer, which acts as a support frame for the equipment. Then, thread the drill rod 4 into the first slide bar 11, and then place the frame 1 directly under the sliding sleeve 21. Pass the third slide bar 3 through the sliding sleeve 21 and thread it into the frame 1 to complete the pre-installation of the equipment. Finally, make fine adjustments to ensure that the equipment is level before powering on to start drilling.

[0035] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
