DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also fall within the scope of protection of the present application.

[0038] As shown in the figure, the present embodiment provides a multi-position telescopic device convenient for online maintenance, which is used for being installed between a first bridge body and a second bridge body, comprising Figures 1-5

[0039] The first support base 1 is used for being arranged on the first bridge body,

[0040] The first toothed plate 2 is arranged on the first support base 1,

[0041] The second support base 3 is arranged on the second bridge body, and the upper part has an arc-shaped groove 301,

[0042] The second toothed plate 4 has an arc-shaped protrusion 401 at the bottom, the arc-shaped protrusion 401 is arranged in rotation in the arc-shaped groove 301, and the rotation axis is parallel to the width direction of the first bridge body, and the second toothed plate 4 also has a second perforation 402,

[0043] The guide rod 5 is arranged at the lower end on the second support base 3, and the upper end penetrates through the second perforation 402,

[0044] The locking bolt 6 is threadedly arranged at the upper end of the guide rod 5 and located above the second toothed plate 4.

[0045] ​In this embodiment, considering that the comb tooth type expansion joint device in the prior art has a large height misalignment in some cases, in order to solve this problem, the first tooth plate 2 is fixed on the first support seat 1, and the second tooth plate 4 can rotate relatively on the arc-shaped groove 301 through the arc-shaped protrusion 401, so as to realize the inclined rotation of the second tooth plate 4 relative to the second support seat 3. When there is a certain deviation in height between the first support seat 1 and the second support seat 3, the car passes through the first tooth plate 2 and the second tooth plate 4, and the second tooth plate 4 rotates a certain amount, so that the first tooth plate 2 and the second tooth plate 4 do not have a high difference, avoiding damage to the car.

[0046] In this embodiment, after the arc-shaped protrusion 401 of the second tooth plate 4 rotates relative to the arc-shaped groove 301, it will be guided and limited by the guide rod 5, so as to ensure the structural stability of the second tooth plate 4 after tilting. The locking bolt 6 at the top of the guide rod 5 can play a limiting role to avoid damage and loss of the second tooth plate 4. In order to avoid the second tooth plate 4 being stuck by the guide rod 5 when rotating, the second perforation 402 can be designed as a short slot, so that the second tooth plate 4 can be clearly realized. The first tooth plate 2 can be provided with a limiting portion 201 at the bottom to limit the second tooth plate 4, so as to further ensure that the first tooth plate 2 and the second tooth plate 4 are flush.

[0047] Further, it further includes a waterproof strip 7, the waterproof strip 7 has a water guide groove 701, the water guide groove 701 is located below the first tooth plate 2 and the second tooth plate 4, one side of the waterproof strip 7 is clamped on the first support seat 1, and the other side is clamped on the second support seat 3.

[0048] Further, it further includes a cleaning assembly 8, the cleaning assembly 8 is arranged above the water guide groove 701, and includes a reciprocating sliding piece 801, the reciprocating sliding piece 801 is slidingly arranged on the first support seat 1 and the second support seat 3, and has a first guide inclined surface 802,

[0049] A lifting pressure piece 803 is slidingly arranged, and has a vehicle pressure portion 804 at the top, the first tooth plate 2 has a first perforation 201, the vehicle pressure portion 804 passes through the first perforation 201 and the upper end is higher than the first tooth plate 2, the lifting pressure piece 803 further has a second guide inclined surface 806, the second guide inclined surface 806 abuts against the first guide inclined surface 802, and when the vehicle pressure portion 804 is pressed down, the second guide inclined surface 806 pushes the first guide inclined surface 802 to make the reciprocating sliding piece 801 slide to one side,

[0050] A first elastic piece 807 is arranged at one end of the reciprocating sliding piece 801 and provides a force for the reciprocating sliding piece 801 to slide to the other side,

[0051] The cleaning brush 808 is arranged at the bottom of the reciprocating slide 801.

[0052] In the embodiment, the waterproof strip 7 is specially used for guiding the water falling in the first tooth plate 2 and the second tooth plate 4 to the two sides of the bridge when it rains. After long-term use, the water guide groove 701 of the waterproof strip 7 often accumulates some dust and sundries. In order to avoid this situation, the cleaning assembly 8 is specially designed. The cleaning assembly 8 can act on the water guide groove 701 of the waterproof strip 7 to clean the dust and sundries accumulated in the water guide groove 701, thereby avoiding the accumulation of dust and sundries in the water guide groove 701 and ensuring that the waterproof strip 7 will not be damaged and can normally work to guide water.

[0053] In the embodiment, the cleaning assembly 8 has a lifting pressure piece 803. The top of the lifting pressure piece 803 is a car pressure part 804. The car pressure part 804 passes through the first perforation 201 of the first tooth plate 2 and is higher than the top of the first tooth plate 2. When a car passes through the cleaning assembly 8, the tire of the car will press down the lifting pressure piece 803, so that the lifting pressure piece 803 moves downward. After the lifting pressure piece 803 moves downward, the second guide inclined surface 806 pushes the first guide inclined surface 802, so that the reciprocating slide 801 slides to one side. The reciprocating slide 801 has a cleaning brush 808 at the bottom. The cleaning brush 808 acts on the water guide groove 701 of the waterproof strip 7, thereby cleaning it. This can well avoid the accumulation of dust and sundries in the water guide groove 701, so that the whole cannot normally work and problems occur.

[0054] In the embodiment, one end of the first elastic piece 807 acts on the reciprocating slide 801, and the other end can act on the first support seat 1 or the second support seat 3. Finally, the reciprocating slide 801 moves to one side to complete the cleaning work of the cleaning brush 808, and then moves to the other side to reset, thereby ensuring that the cleaning brush 808 works reciprocally. The cleaning brush 808 has a large number of quantities. Each cleaning brush is responsible for cleaning a small section of the water guide groove 701 of the waterproof strip 7. Finally, the whole cleaning of the water guide groove 701 is realized, and the vast majority of positions of the water guide groove 701 can be cleaned.

[0055] Further, the cleaning assembly 8 further includes a second elastic piece 809. One end of the second elastic piece 809 acts on the bottom of the lifting pressure piece 803 to provide a lifting force for the lifting pressure piece 803.

[0056] In the embodiment, a second elastic member 809 is also designed, one end of the second elastic member 809 acts on the bottom of the lifting and pressing member 803, and the other end can act on the first support base 1 or the second support base 3. After the lifting and pressing member 803 is pressed down and the car is away from the lifting and pressing member 803 and no longer presses the lifting and pressing member 803, the second elastic member 809 acts on the lifting and pressing member 803 to make it rise and reset, thereby effectively ensuring the subsequent cleaning action of the cleaning brush 808 and achieving good effect. The second elastic member 809 can be selected as a suitable spring.

[0057] Further, the reciprocating sliding member 801 has a guide portion 810 on both sides, and the side wall of the first support base 1 and the second support base 3 has an annular guide groove 9, and the guide portion 810 is slidingly arranged in the annular guide groove 9.

[0058] In the embodiment, the guide of the reciprocating movement of the reciprocating sliding member 801 is realized by the guide portion 810 on both sides of the reciprocating sliding member 801 sliding in the annular guide groove 9, thereby effectively ensuring the sliding stability of the reciprocating sliding member 801 and effectively avoiding damage to the whole. Considering that the distance between the first bridge body and the second bridge body will change, the guide portion 810 can also slide along the depth direction of the annular guide groove 9, thereby ensuring that when the distance between the first bridge body and the second bridge body changes, the guide portion 810 of the reciprocating sliding member 801 can also be guided in the annular guide groove 9 at all times.

[0059] Further, the annular guide groove 9 is divided into a horizontal section 901 and a downward section 902, and the two ends of the horizontal section 901 are respectively connected to the two ends of the downward section 902.

[0060] In the embodiment, the annular guide groove 9 is divided into a horizontal section 901 and a downward section 902, and the starting position of the cleaning brush 808 also has a distance relative to the water guide groove 701. When the guide portion 810 slides in the downward section 902, the cleaning brush 808 can slide downward from the starting position at a certain height, thereby realizing that the cleaning brush 808 moves from close to the water guide groove 701 to closely contact the water guide groove 701, and continues to move horizontally to clean the water guide groove 701. After that, the cleaning brush 808 rises to a certain height, and finally the guide portion 810 slides to the horizontal section 901 for horizontal reset, so as to ensure that the next cleaning action is effectively performed.

[0061] Further, the downward section 902 is arc-shaped.

[0062] In the embodiment, the downward section 902 is designed to be arc-shaped, and the guide portion 810 can first descend along the downward section 902 to clean the water guide groove 701, and then rise to the horizontal section 901 for reset, thereby effectively ensuring the cleaning effect of the cleaning brush 808 on the water guide groove 701.

[0063] Further, the downward section 902 is divided into a first inclined section 9021, a horizontal sweeping section 9022 and a second inclined section 9023, which are sequentially communicated.

[0064] In the embodiment, the downward section 902 can also be designed as the first inclined section 9021, the horizontal sweeping section 9022 and the second inclined section 9023, the first inclined section 9021 is gradually descending, so that the cleaning brush 808 is close to the water guide groove 701, the guide part 810 slides along the horizontal sweeping section 9022, thereby adhering to the water guide groove 701 for cleaning, and finally rises along the second inclined section 9023, the design of the horizontal sweeping section 9022 improves the cleaning degree of the water guide groove 701, and further improves the cleaning effect.

[0065] Further, the shape of the cleaning brush 808 matches the shape of the water guide groove 701, and the vehicle pressing part 804 is cylindrical and has a chamfered top.

[0066] In the embodiment, the shape of the cleaning brush 808 matches the shape of the water guide groove 701, which further ensures the cleaning effect, and the vehicle pressing part 804 is cylindrical and has a chamfered top, which can well avoid damage when the vehicle presses the vehicle pressing part 804, thereby improving the stability of the equipment.

[0067] Further, the cleaning brush 808 is divided into a first cleaning brush 8081 and a second cleaning brush 8082, both of which are slidingly arranged at the bottom of the reciprocating sliding part 801, and the cleaning assembly 8 further comprises a third elastic member 811, one end of which acts on the first cleaning brush 8081, and the other end of which acts on the second cleaning brush 8082, thereby providing a force for moving the first cleaning brush 8081 and the second cleaning brush 8082 away from each other.

[0068] In the embodiment, considering that the water guide groove 701 of the waterproof strip 7 is usually V-shaped, after the distance between the first bridge body and the second bridge body changes due to some reasons, the angle of the V-shaped groove will also change, in order to ensure that the cleaning brush 808 can better clean the water guide groove 701, the cleaning brush 808 is designed to be divided into the first cleaning brush 8081 and the second cleaning brush 8082, and the third elastic member 811 moves the first cleaning brush 8081 and the second cleaning brush 8082 away from each other, so that the first cleaning brush 8081 and the second cleaning brush 8082 can better adhere to the water guide groove 701, thereby further improving the cleaning effect of the water guide groove 701.

[0069] The above are only the preferred embodiments of the present application and are not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
