[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.
[0022] Some embodiments of the present invention are described below with reference to the accompanying drawings.
[0023] Example 1:
[0024] Combine Figure 1-4 As shown, this embodiment provides a bridge maintenance pylon, including: a main body mechanism 100 and a suspension mechanism 200.
[0025] Among them, the main mechanism 100 includes a base 110, a support plate 120 fixed on one side of the base 110, a pull rod 130 symmetrically arranged with one end connected to the base 110 and the other end fixed to the support plate 120, a counterweight placement plate 140 symmetrically fixed on both sides of the base 110, a ladder 150 installed on one side of the support plate 120, and a plurality of universal wheels 160 installed at the bottom end of the base 110.
[0026] The base 110 is used to install other components to ensure the stability of each component. The support plate 120 is used to support the suspension mechanism 200 to ensure the stability of the suspension mechanism 200. The pull plate fixes the support plate 120 and the base 110 together to form a whole, thereby improving the structural strength.
[0027] The counterweight placement plate 140 is used to place the counterweight, the ladder 150 facilitates workers to enter the suspension structure, and the universal wheel 160 facilitates the movement of the entire base 110, thereby improving the convenience of moving the rack.
[0028] The suspension mechanism 200 includes a protective frame 210 whose end is hingedly mounted on the support plate 120, a winding member 220 mounted on the top of the protective frame 210, a driving member 230 mounted on the top of the protective frame 210 and engaged with the winding member 220, a steel wire rope 240 with one end wound around the winding member 220 and the other end passing through the protective frame 210 and extending downward, a hanging basket 250 fixed to the end of the steel wire rope 240, and an electric telescopic rod 260 symmetrically mounted on the pull rod 130 and hinged to the pull rod 130 at one end and hinged to the protective frame 210 at the other end.
[0029] By setting the protective frame 210, workers are located in the inner cavity of the protective frame 210 when they are getting on and off the hanging basket 250, which can effectively avoid risks in the process of workers getting on and off the hanging basket 250, thereby improving safety. In addition, a fixed shaft 121 is fixed on one side of the support plate 120, and a sleeve 211 is fixed on one side of the protective frame 210. The sleeve 211 is rotatably sleeved on the fixed shaft 121, which facilitates the overall rotation of the protective frame 210. Through the rotation of the protective frame 210, the overall occupied space of the rack is reduced, and it is convenient to move.
[0030] The winding member 220 is used to wind the wire rope 240 and drive the wire rope 240 to be retracted and released. The winding member 220 includes a rotating shaft 221 rotatably installed at the top of the protective frame 210, a reel 222 symmetrically fixed on both sides of the rotating shaft 221, and a worm gear 223 fixedly sleeved on the middle part of the rotating shaft 221. At the same time, the driving member 230 includes a motor 231 installed at the top of the protective frame 210 and a worm 232 fixed on the shaft of the motor 231. The worm 232 and the worm gear 223 are engaged with each other, so that when the motor 231 rotates, it drives the worm 232 to rotate, and the rotation of the worm 232 drives the worm gear 223 to rotate. The rotation of the worm gear 223 drives the rotating shaft 221 to rotate, and the rotation of the rotating shaft 221 drives the reel 222 to rotate. The rotation of the reel 222 drives the wire rope 240 to be retracted and released, thereby controlling the height of the hanging basket 250.
[0031] One end of the wire rope 240 is wound around the reel 222, and the other end passes through the protective frame 210 and is fixed to the hanging basket 250, which is used to drive the hanging basket 250 to move up and down. The hanging basket 250 is used for workers to enter and facilitate the inspection of the outer side of the bridge. The hanging basket 250 includes a hanging basket 251 fixed to the end of the wire rope 240 and an inward-opening door 252 symmetrically installed on one side of the hanging basket 251. The setting of the inward-opening door 252 can prevent it from opening suddenly during the inspection process.
[0032] One end of the electric telescopic rod 260 is hinged to the pull rod 130 , and the other end is hinged to the protection frame 210 , so as to drive the protection frame 210 to rotate.
[0033] The working principle and use process of the utility model are as follows: when in use, the electric telescopic rod 260 is started, driving the protective frame 210 to rotate, so that the protective frame 210 is rotated to the top of the support plate 120, and the counterweight block is placed on the counterweight placement plate 140. The worker enters the hanging basket 250 through the ladder 150. Due to the setting of the protective frame 210, the worker avoids the risk of getting on and off the hanging basket 250. Then the motor 231 is started, driving the worm 232 to rotate, and the rotation of the worm 232 drives the worm wheel 223 to rotate. The worm gear 223 rotates to drive the rotating shaft 221 to rotate, and the rotating shaft 221 rotates to drive the reel 222 to rotate, so that the wire rope 240 on the reel 222 is released. As the wire rope 240 is released, the hanging basket 250 gradually moves down, which is convenient for workers to inspect the bridge. When the inspection is completed, the hanging basket 250 is retracted into the protective frame 210. At this time, the electric telescopic rod 260 contracts, driving the protective frame 210 to rotate and drive the top of the base 110. At this time, pushing the overall structure to move can facilitate the transfer of the hanging rack.
[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
