Description
Technical Field
[0001] The utility model relates to the technical field of bridge side construction, and specifically relates to a suspended hanging basket for bridge side construction. Background Art
[0002] Bridge side construction generally includes work contents such as spraying real stone paint and installing drainage pipes. At present, when carrying out construction work such as spraying real stone paint and installing drainage pipes, workers need to stand on one side of the bridge side. When spraying real stone paint, generally, workers can directly spray the real stone paint on the bridge deck by controlling the real stone paint spray head. Therefore, there is no need for workers to keep too close contact with the bridge side. Thus, the existing suspended hanging basket can completely realize the suspended spraying operation of workers. However, since the underside of the flange plate on the bridge side is an inclined surface that slopes towards the center of the bridge, when fixing the drainage pipe under the flange plate, workers need to keep close contact with the inclined side under the flange plate. Since the existing suspended hanging baskets generally use steel wires to achieve the vertical downward movement of the manned hanging basket, when the design and installation position of the drainage pipe is relatively low, it will result in a relatively large distance between the manned hanging basket and the installation position of the drainage pipe, thus making it impossible to achieve the positioning and installation of the drainage pipe. At the same time, the manned hanging basket of the existing suspended hanging basket is generally suspended and supported by two brackets during erection. This leads to the inability to adjust the position of the manned hanging basket during operation, resulting in the inability to flexibly adjust its working range. Further, when the manned hanging basket needs to be moved, it is necessary to coordinate the movement of the two brackets, resulting in a more cumbersome re-erection and movement of the existing suspended hanging basket.

Detailed implementation manners
[0019] The following will combine specific embodiments and appendices Figures 1 - 4 , and clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some preferred embodiments of the present invention, rather than all embodiments. Those skilled in the art can make similar deformations without violating the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0020] The present invention provides a suspended hanging basket for bridge side construction (such as Figure 1As shown in the figure, it includes a manned hanging basket 8, an electric flatbed truck 1, a fixed bracket 2, a lifting bracket 3, a lifting drive mechanism, a connecting seat 5, a connecting hanging bracket 6, and a counterweight 7. The manned hanging basket 8 is a commonly used manned basket for high-altitude operations in the existing technology. The electric flatbed truck 1 is a mature flatbed cargo handling and moving tool on the existing market. It has the ability of independent movement and a relatively high load capacity, and its movement and walking control can be realized through manual driving or wireless remote control. In this specific embodiment, by using the moving ability of the electric flatbed truck 1, the movement of the entire hanging basket can be achieved. Compared with the existing hanging basket moving methods, it has the advantages of high moving efficiency and convenience. The fixed bracket 2 is fixedly arranged on the electric flatbed truck 1. The lifting bracket 3 is arranged on the fixed bracket 2, and the lifting bracket 3 can be adjusted up and down under the drive of the lifting drive mechanism. The lifting bracket 3 includes a suspension support rod 31. The connecting seat 5 is connected to the end of the suspension support rod 31 away from the electric flatbed truck 1. The connecting seat 5 can reciprocate horizontally on the suspension support rod 31. The upper part of the connecting hanging bracket 6 is connected to the connecting seat 5, and the connecting hanging bracket 6 can rotate freely relative to the connecting seat 5. The manned hanging basket 8 is fixedly arranged at the bottom of the connecting hanging bracket 6. By using the left and right moving ability of the connecting seat 5 relative to the cantilever support rod 31, the left and right adjustment function of the manned hanging basket 8 is realized. By using the up and down lifting ability of the lifting bracket 3, the up and down adjustment function of the manned hanging basket 8 is realized. By using the rotating ability of the connecting hanging bracket 6, the rotating adjustment function of the manned hanging basket 8 in the horizontal plane is realized. During the operation, the staff stands in the manned hanging basket 8. By using the up and down adjustment function, left and right adjustment function and rotation function of the manned hanging basket 8, the working range of the staff can be flexibly adjusted to a certain extent, thus facilitating the construction operation on the side of the bridge. In practical applications, the manned hanging basket 8 can be located below the inclined plane of the bridge flange plate, so as to facilitate the staff to carry out bridge side construction projects such as drainage pipe installation under the flange plate. A control box is arranged on the connecting hanging bracket 6 above the manned hanging basket 8. A number of the counterweights 7 are placed on the electric flatbed truck 1. By using the pressing effect of the counterweights 7 on the electric flatbed truck 1, it effectively ensures that the entire hanging basket will not tip over during the construction operation, thereby improving the operation safety.
[0021] On the basis of the above embodiment, the specific implementation manner of the fixed bracket 2 is as follows: The fixed bracket 2 includes four support vertical pipes 21. The support vertical pipes 21 are processed from square steel pipes. The four support vertical pipes 21 are fixedly arranged on the electric flatbed truck 1 in a square distribution. The upper parts of adjacent support vertical pipes 21 are fixedly connected through a connecting rod 22. Through the connection of the connecting rod 22, the structural strength and stability of the fixed bracket 2 can be improved as a whole, and then an effective and stable support can be provided for the lifting bracket 3.
[0022] On the basis of the above embodiments, the specific implementation of the lifting bracket 3 is as follows: Four support vertical rods 32 are provided at the lower left of the lifting bracket 3, and the suspension support rod 31 is located on the right side of the four support vertical rods 32. In practical applications, the suspension support rod 31 is in a cantilever beam structure relative to the four support vertical rods 32, so as to facilitate the suspension of the manned hanging basket 8 on the side of the bridge by using the suspension support rod 31. The four support vertical rods 32 are respectively sleeved in the corresponding four support vertical pipes 21. A plurality of adjustment holes 321 are provided on the side wall of the support vertical rod 32, and a positioning hole 211 adapted to the adjustment hole 321 is provided at the top of the support vertical pipe 21. A pin shaft is inserted into the positioning hole 211 and the corresponding adjustment hole 321 to realize the positioning of the support vertical rod 32 in the support vertical pipe 21. In practical applications, the height adjustment and positioning of the suspension support rod 31 are realized by the cooperation of the positioning hole 211 and different adjustment holes 321. Further, the lifting drive mechanism includes a hydraulic cylinder 4. The fixed end of the hydraulic cylinder 4 is provided on the electric flatbed truck 1, and the movable end of the hydraulic cylinder 4 is connected to the lower left end of the lifting bracket 3. The lifting adjustment of the lifting bracket 3 can be realized by the telescopic movement of the hydraulic cylinder 4, and then the up and down height adjustment of the manned hanging basket 8 can be finally realized. After the lifting adjustment of the lifting bracket 3 is realized by using the hydraulic cylinder 4, the pin shaft is inserted into the positioning hole 211 and the corresponding adjustment hole 321 to fix the lifting bracket 3. The hydraulic cylinder 4 is a commonly used technical product in the prior art field, and the hydraulic system for realizing its telescopic movement is also in the prior art. Therefore, the structural composition of the hydraulic system for assisting the hydraulic cylinder 4 to realize the telescopic function will not be introduced in detail. In practical applications, the hydraulic system working in cooperation with the hydraulic cylinder 4 is arranged on the electric flatbed truck 1, so as to increase the self-weight of the electric flatbed truck 1, and then reduce the number of counterweight blocks 7 used to a certain extent.
[0023] On the basis of the above embodiments, the specific implementation manner for the connecting seat 4 to move left and right relative to the suspension support rod 31 is as follows: The connecting seat 5 is a square hollow frame. The connecting seat 5 is sleeved on the right end of the suspension support rod 31, and a limiting plate 34 is fixedly arranged at the right end of the suspension support rod 31. By utilizing the blocking and limiting function of the limiting plate 34, the connecting seat 5 can be effectively prevented from falling off the right end of the suspension support rod 31. The front and rear side walls inside the connecting seat 5 are respectively in contact with the corresponding front and rear side walls of the suspension support rod 31, thereby improving the moving stability of the connecting seat 5 on the suspension support rod 31. A rack 33 is arranged on the upper part of the suspension support rod 31, a driving gear 51 is arranged in the connecting seat 5 above the rack 33, and the driving gear 51 meshes with the rack 33. A first braking motor 52 for driving the driving gear 51 is arranged on the connecting seat 5. In practical applications, the driving gear 51 is rotatably arranged in the connecting seat 5 by a support rotating shaft, and the output shaft of the first braking motor 52 is directly connected to the support rotating shaft. Thus, the rotation of the driving gear 51 is realized by the rotation of the first braking motor 52. When the driving gear 51 rotates, due to its meshing relationship with the rack 33, the movement of the connecting seat 5 is realized, and ultimately the movement of the manned hanging frame 8 is realized. When the first braking motor 52 is not working, the braking device it has can realize the passive rotation of the output shaft, thereby ensuring the stability of the driving gear 51 on the rack 33. A limiting pin shaft 53 is arranged on the connecting seat 5 below the suspension support rod 31, and the outer side wall of the upper part of the limiting pin shaft 53 is in contact with the lower bottom surface of the suspension support rod 31. By utilizing the cooperation relationship between the limiting pin shaft 53 and the suspension support rod 31, the moving stability of the connecting seat 5 on the suspension support rod 31 can be further improved, and thus the safety of high-altitude operations is improved.
[0024] On the basis of the above embodiments, the specific implementation manner in which the connecting hanging frame 6 drives the manned hanging basket 8 to achieve free rotation is as follows: A first bevel gear 54 capable of freely rotating is vertically arranged at the lower part of the connecting seat 5. To achieve the flexible and free rotation of the first bevel gear 54 on the connecting seat 5, here, a plain bearing 541 is sleeved on the cone shaft of the first bevel gear 54, and the plain bearing 541 is located between the inner bottom plane of the connecting seat 5 and the first bevel gear 54. A second bevel gear 55 meshing with the first bevel gear 54 is arranged on the side wall of the connecting seat 5. A second braking motor 56 for driving the second bevel gear 55 is arranged on the connecting seat 5. The second braking motor 56 is fixedly arranged on the connecting seat 5, and the output shaft of the second braking motor 56 is connected to the second bevel gear 55. When the second braking motor 56 drives the second bevel gear 55 to rotate actively, the rotation of the first bevel gear 54 is achieved by using the meshing relationship between the first bevel gear 54 and the second bevel gear 55. The upper part of the connecting hanging frame 6 is fixedly connected to the bottom of the first bevel gear 54. When the first bevel gear 54 rotates, the connecting hanging frame 6 is synchronously driven to rotate. The rotation of the connecting hanging frame 6 realizes the rotation of the manned hanging basket 8. Since the second braking motor 56 has a braking function, when it is not working, the rotation of the manned hanging basket 8 can be effectively prevented, thereby improving the operation safety.
[0025] To facilitate the smooth realization of the up-and-down, left-and-right and rotation control of the manned hanging basket 8, here, a controller is arranged in the control box 9. The controller is used to control the operation of the electric flatbed truck 1, the hydraulic cylinder 4, the first braking motor 52 and the second braking motor 56. When the staff uses the controller to control the movement of the electric flatbed truck 1, in order to ensure the movement safety, it is necessary to cooperate with the staff on the bridge deck. After ensuring the movement safety on the bridge deck, the staff on the bridge deck notifies the staff in the manned hanging basket 8 to perform the movement control of the electric flatbed truck 1. At the same time, to improve the movement controllability of the electric flatbed truck 1, the staff located on the bridge deck can also realize the movement control of the electric flatbed truck 1 through the control system arranged on the electric flatbed truck 1. The staff located in the manned hanging basket 8 controls the lifting of the hydraulic cylinder 4 through the control panel according to the actual working position requirements. After completing the lifting control of the hydraulic cylinder 4, it is necessary to use the pin to realize the relative fixation of the support vertical pipe 21 and the support vertical rod 32 again. By controlling the forward and reverse rotation of the first braking motor 52, the left-and-right adjustment and positioning of the working position are realized. By controlling the forward and reverse rotation of the second braking motor 56, the rotation adjustment of the working position in the horizontal plane is realized.
[0026] To improve the support strength of the suspension support rod 31, a reinforcement truss 35 can be fixedly arranged on the upper left side of the lifting bracket 3. During construction operations, the initial erection of the present utility model on the bridge surface is first achieved by using hoisting equipment. Then, by utilizing the automatic movement and adjustment capabilities of the present utility model, the adjustment of the corresponding workstations is realized, thereby facilitating the construction operations on the side of the bridge by the staff using the support of the manned hanging basket 8.
[0027] In the present utility model, "upper", "lower", "front", "rear", "left", and "right" are all relative positions used for conveniently describing the positional relationship, and therefore cannot be understood as absolute positions to limit the protection scope.
[0028] Except for the technical features described in the specification, they are all known technologies to those skilled in the art.
[0029] As described above, the preferred embodiments and examples of the present utility model have been described in detail in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments and examples. For those of ordinary skill in the art in this technical field, without departing from the concept of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
