[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A bridge pier maintenance device includes an annular spray pipe 2 sleeved on the bridge pier 1. The annular spray pipe 2 is a hard metal pipe. Sprinkler heads 201 in a ring array are fixedly installed on the annular spray pipe 2. The sprinkler heads 201 are connected to the annular spray pipe 2. The sprinkler heads 201 are used to spray water onto the surface of the pier 1 to maintain the pier 1.

[0025] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The bottom of the annular spray pipe 2 is equipped with at least three sets of positioning mechanisms 3, which are arranged equidistantly in a circular pattern. These positioning mechanisms 3 include a fixed rod 301, a vertical round rod. A fixed sleeve 302 is fixedly mounted at the bottom of the rod 301. The sleeve 302 has a cavity within it, and a connecting cross plate 303 is slidably connected to the sleeve 302. A connecting bracket 304 is fixedly connected to one end of the connecting cross plate 303. An adjusting wheel 305 is rotatably connected to the connecting bracket 304. The adjusting wheel 305 is vertically arranged and has a wear-resistant rubber pad on its surface, which serves as the contact surface with the surface of the pier 1 and abuts against it, thereby achieving the desired positioning of the annular spray pipe 2. The adjusting wheel 305 is a lightweight, small wheel that gently contacts the surface of the pier 1 to avoid damaging the undried surface.

[0026] like Figure 3 and Figure 4 A slide groove 4 is provided at the bottom of the fixed sleeve 302, and a connecting slider 5 is fixedly connected to the bottom of the connecting cross plate 303. The connecting slider 5 and the slide groove 4 are slidably connected. The connecting slider 5 is an inverted T-shaped design, with one part located in the slide groove 4 and one part protruding from the outside of the fixed sleeve 302, which can limit the movable distance of the connecting cross plate 303 and prevent the connecting cross plate 303 from detaching from the inside of the fixed sleeve 302.

[0027] like Figure 3 and Figure 4 The bottom of the fixed sleeve 302 is fixedly connected to a fixed block 6, and the fixed block 6 is threadedly connected to an adjusting screw 7. One end of the adjusting screw 7 is rotatably connected to the connecting slider 5 to drive the connecting slider 5 and the connecting cross plate 303 to move together.

[0028] like Figure 1 , both sides of the pier 1 are provided with a lifting mechanism, which includes a supporting top frame 801 and a winch 802. The winch 802 is a prior art. The winches 802 on both sides of the pier 1 operate synchronously, and finally realize the horizontal lifting of the annular spray pipe 2, and the lifting rope 804 can be released and reeled in. A fixed pulley 803 is fixedly installed at the bottom of the supporting top frame 801, and a lifting rope 804 is connected to the winch 802. One end of the lifting rope 804 passes through the fixed pulley 803 and is fixedly connected to the annular spray pipe 2. The lifting rope 804 passes through the top of the fixed pulley 803, so that the lifting rope 804 will not fall off, and is used to drive the annular spray pipe 2 to move up and down.

[0029] like Figure 1 A support hoop 9 is installed on the top of the pier 1, and the support hoop 9 is locked on the outer surface of the top of the pier 1. The support top frame 801 is fixed on the support hoop 9, and the two support top frames 801 are horizontally arranged on both sides of the support hoop 9. The winch 802 is set on the ground on both sides of the pier 1 and fixed to the ground by ground nails. A reinforcement brace 10 is fixedly connected between the support top frame 801 and the support hoop 9, which can improve the supporting strength of the reinforcement brace 10.

[0030] like Figure 1 A connecting pipe head is provided at the bottom of the annular spray pipe 2, and a delivery hose 11 is fixedly installed on the connecting pipe head. A flange is used to fix the connecting head and the delivery hose 11. The other end of the delivery hose 11 is connected to an external water pump, and the water pump delivers the external water source to the inside of the annular spray pipe 2 through the delivery hose 11.

[0031] The working principle of the bridge pier maintenance device provided by the utility model is as follows:

[0032] When the bridge pier 1 needs to be sprayed for maintenance, the external water pump delivers external water to the inside of the annular spray pipe 2 through the delivery hose 11, and the hoist 802 reels and releases the lifting rope 804. When the lifting rope 804 is reeled in, the lifting rope 804 drives the annular spray pipe 2 to rise. When the lifting rope 804 is released, the annular spray pipe 2 descends under the action of gravity.

[0033] During the process of raising and lowering the annular spray pipe 2, the spray head 201 sprays water onto the surface of the pier 1 to maintain the pier 1;

[0034] By rotating the adjusting screw 7 in different directions, the adjusting screw 7 will drive the connecting slider 5 to move, and the connecting slider 5 will drive the connecting cross plate 303 to move. The connecting cross plate 303 will drive the connecting bracket 304 and the adjusting wheel 305 to move in different directions, so that the distance between the adjusting wheel 305 and the bridge pier 1 can be adjusted. When the bridge pier 1 is relatively in the center position of the annular spray pipe 2, all the adjusting wheels 305 are in contact with the surface of the bridge pier 1. At this time, the distance between the sprinkler head 201 and the surface of the bridge pier 1 is consistent, and the annular spray pipe 2 will not shake when it moves up and down.

[0035] Compared with related technologies, the bridge pier maintenance device provided by the present invention has the following beneficial effects:

[0036] The utility model drives the annular spray pipe 2 to be raised and lowered by the winch 802. During the raising and lowering process of the annular spray pipe 2, the bridge pier 1 is sprayed and maintained. At the same time, the position of the adjusting wheel 305 is adjusted by rotating the adjusting screw 7, so that the adjusting wheel 305 contacts the surface of the bridge pier 1, which neither affects the raising and lowering of the annular spray pipe 2 nor prevents the annular spray pipe 2 from shaking during the raising and lowering process. The distance between the spray head 201 and the surface of the bridge pier 1 is kept consistent during the raising and lowering process of the annular spray pipe 2, thereby achieving more uniform and sufficient spray maintenance on the surface of the bridge pier 1.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
