Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses impurity cleaning device at multidirectional fishback expansion joint that shifts.

Referring to fig. 1, the impurity cleaning device at multidirectional fishback expansion joint that shifts includes concrete base course, and central authorities' activity fishback 2 and fixed fishback 3 all connect on concrete base course 1 according to detachable mode among the prior art.

Referring to fig. 1 and 2, the concrete base layer 1 is provided with accommodating cavities 101 at staggered positions of comb teeth on the movable comb plate 2 and the fixed comb plate 3 relative to the center, and the accommodating cavities 101 are parallel to the length direction of the expansion joint. A bearing mechanism for bearing impurities entering the cavity and a lifting mechanism for driving the bearing mechanism to lift are arranged in the accommodating cavity 101.

Referring to fig. 1 and 2, the bearing mechanism includes a bearing plate 41 and a plurality of bearing portions, the bearing plate 41 is horizontally disposed and parallel to the length direction of the accommodating cavity 101; the bearing parts are positioned on the upper surface of the bearing plate 41, and one bearing part corresponds to one cavity.

Because the existence of holding chamber 101 for the crisscross position of broach is unsettled on central authorities' activity fishback 2 and the fixed fishback 3, consequently the broach receives the action of gravity of vehicle, can be to taking place deformation in holding chamber 101, and then produces harmful effects to the normal travel of vehicle.

For this purpose, a plurality of supporting bars 9 are integrally formed at the position of the concrete base layer 1 opposite to the bottom of the accommodating cavity 101, and the bearing plate 41 is slidably sleeved on the supporting bars 9. One support bar 9 corresponds to one comb tooth, and the top surface of the support bar 9 is supported on the lower surface of the corresponding comb tooth.

Referring to fig. 2 and 3, the bearing part includes two fixing blocks 42 bolted to the bearing plate 41 and a sliding rod 43, the two fixing blocks 42 have respective open blind holes 421 on opposite side walls, and the sliding rod 43 is located between the two fixing blocks 42 and has an end inserted in the blind hole 421.

The bearing part also comprises two bearing arms 44 which are sleeved on the sliding rod 43 in a sliding way, and a pressure spring 45 which is supported between the two bearing arms 44 in a propping way, wherein the pressure spring 45 is sleeved on the sliding rod 43.

The two bearing arms 44 vertically extend upwards into the corresponding cavities, elastic bearing covers 46 are sleeved between the arm bodies at the tops of the two bearing arms 44 and located in the cavities, and the elastic bearing covers 46 are bonded with the bearing arms 44.

Under the action of the pressure spring 45, the two bearing arms 44 are matched to expand the elastic bearing cover 46, and the bearing arms 44 tightly support the elastic bearing cover 46 against the side walls of the corresponding cavity, namely the movable comb plate 2 and the fixed comb plate 3.

When the central movable comb plate 2 moves, the bearing arm 44 is pushed to slide on the sliding rod 43, and the elastic bearing cover 46 is deformed to a certain extent.

In this process, the elastic bearing cover 46 can be always tightly attached to the central movable comb plate 2 and the fixed comb plate 3 corresponding to the cavity. Impurities such as stones on the road surface fall onto the elastic bearing cover 46 after entering the cavity.

Referring to fig. 2 and 3, when impurities enter the cavity, the impurities exert a certain pressure on the elastic bearing cover 46 under the action of the wheel of the vehicle, and the top of the elastic bearing cover 46 deforms. When the foreign matter is relatively sharp, the elastic bearing cap 46 is relatively vulnerable to damage.

For this reason, the worker can replace the single carrier as a whole by bolting the fixing block 42 to the carrier plate 41.

Referring to fig. 2 and 4, two screw rods 52 are respectively fixedly sleeved with a synchronous sprocket (not shown), a synchronous chain 6 is sleeved between the two synchronous sprockets, and the synchronous chain 6 is located below the bearing plate 41.

Through the cooperation of the synchronous chain wheel and the synchronous chain 6, the synchronous rotation between the two screw rods 52 is realized, and the possibility that the bearing plate 41 is inclined and the bearing part is difficult to lift due to the rotation speed difference existing when the two screw rods 52 rotate is reduced.

Referring to fig. 2 and 4, currently, the fast sweeping method usually adopted is for a worker to manually sweep with a broom, and if the carrying part pushes up impurities, the carrying part is higher than the upper surfaces of the central movable comb plate 2 and the fixed comb plate 3, which inevitably brings certain inconvenience to sweeping the impurities with the broom, and for this reason, it is the best case that the upper surface of the elastic carrying cover 46 is just flush with the upper surfaces of the central movable comb plate 2 and the fixed comb plate 3.

If the worker directly observes whether the upper surface of the elastic bearing cover 46 is flush with the upper surfaces of the central movable comb plate 2 and the fixed comb plate 3 by naked eyes, certain inconvenience exists, and a display mechanism is further arranged at the road teeth.

The display mechanism comprises a solar generator 71 arranged on the curbs through expansion bolts, a storage battery of the solar generator 71 is electrically connected to an electrical pin 72, and the electrical pin 72 is bolted on the lower surface of the fixed comb plate 3 corresponding to the end part of the bearing plate 41.

When the light bulb 74 is just lit, the operator stops operating the lifting portion, and the upper surface of the elastic bearing cover 46 is just flush with the upper surfaces of the central movable comb plate 2 and the fixed comb plate 3.

After the cleaning is completed, the lifting part drives the bearing plate 41 to descend to realize resetting, the conductive column 73 is disconnected from the electrical pins 72, and the lamp 74 is turned off.

Referring to fig. 1 and 4, in order to reduce the possibility that a passer-by will operate the cleaning apparatus, a hollow interior protective box 8 is bolted to the curb, one elevating part is corresponding to each protective box 8, the elevating part is located in the corresponding protective box 8, and a light bulb 74 is installed in the protective box 8.

The protective box 8 is locked through the lockset, and only when a cleaning worker opens the protective box 8 through a key, the cleaning device can be operated to clean.

The implementation principle of the impurity cleaning device at multidirectional fishback expansion joint that shifts of this application embodiment is: under the action of the pressure spring 45, the two bearing arms 44 are matched to expand the elastic bearing cover 46, so that the elastic bearing cover 46 is tightly attached to the side walls of the central movable comb plate 2 and the fixed comb plate 3 corresponding to the cavity, and impurities can only be accumulated on the elastic bearing cover 46 after entering the cavity.
