Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction equipment, in particular to material transportation equipment for bridge bottom surface construction. Background Art

[0002] After the main construction of the bridge road is completed or when the bridge is repaired and maintained in the later stage, a large number of bridge bottom surface construction operations are involved, such as the erection of pipelines, the installation and maintenance of street lights, or the painting of the bottom surface of the steel box beam, etc. In the construction process of the corresponding environment, it is necessary to transport a variety of materials. In the existing technology, pulling ropes and suspension devices are mostly used to lift materials. The overall operation is not only cumbersome but also has great safety hazards, which affects the work efficiency of the staff in the later stage. Therefore, it is necessary to provide a new material transportation equipment for bridge bottom surface construction to solve the above technical problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a material transportation equipment for bridge bottom surface construction. The loading transport basket in the utility model is convenient to adjust the vertical and horizontal positions, which can effectively improve the convenience and stability of material transportation.

[0004] The utility model provides a material transport device for bridge bottom surface construction, comprising a support frame provided with a transport assembly, wherein the transport assembly comprises a guide frame mounted on a side wall of the support frame, a sliding plate is slidably provided on the guide frame, a rotatably connected winding rod is mounted on the top of the sliding plate, winding ropes are wound on both sides of the winding rod, and the ends of the winding ropes pass through the sliding plate and are provided with a transport basket;

[0005] A rotatably connected driving screw is provided on one side of the top of the guide frame, a threaded connecting tube is sleeved on the outside of the driving screw, and the outer wall of the connecting tube is fixedly connected to the top of the sliding plate;

[0006] A driving vehicle is provided at the bottom end of the supporting frame.

[0007] In the later use process, the staff can place the materials on the transport basket, and then control the transport basket to move vertically and horizontally, so that the staff on the suspended working platform at the bottom of the bridge can take the materials in the transport basket, which can effectively improve the convenience and stability of material transportation; at the same time, the driving vehicle can be controlled to work, so that the utility model can move synchronously with the suspended working platform of the staff. At the same time, the winding motor is a self-locking motor, and then when the transport basket is suspended for feeding in the later stage, the transport basket can be positioned by self-locking to avoid the transport basket from falling.

[0008] Preferably, a connecting frame is vertically slidably connected to the support frame, a driving hydraulic cylinder is arranged between the connecting frame and the support frame, and a roller for clamping against the two sides of the curb is arranged under the support frame. When in use later, the two rollers can respectively press against the two sides of the bridge curb, thereby providing safety protection again and preventing the danger of the entire vehicle tipping over due to excessive counterweight of the transport basket.

[0009] Preferably, the connecting frame is provided with a clamping hydraulic cylinder at both sides of the corresponding curbstone, the output end of the clamping hydraulic cylinder is provided with a mounting plate, and the mounting plate and the connecting frame are connected by a telescopic sleeve;

[0010] The mounting plate is movably connected to the roller.

[0011] Preferably, the sliding rod passes through the mounting plate and slides with the mounting plate, a limiting flange is provided at the end of the sliding rod away from the curb, a spring is sleeved on the sliding rod body between the limiting flange and the mounting plate, the end of the sliding rod facing the curb is connected to the mounting frame, and the roller is rotatably connected to the bracket on the mounting frame.

[0012] When the clamping hydraulic cylinder drives the roller to move, the outer wall of the roller is against the outer wall of the bridge curb. When the driving vehicle moves, the spring on the outer wall of the slide rod can use its own force to drive the mounting frame to squeeze the roller against the curb, ensuring that the roller always contacts the curb. At the same time, the roller rotates under the action of friction, so that the surface friction is converted into rolling friction, thereby increasing the moving resistance of the device.

[0013] Specifically, a winding motor is provided at one end of the winding rod, and the winding motor is mounted on the sliding plate.

[0014] Specifically, a driving motor is provided at one end of the driving screw rod, and the driving motor is mounted on the guide frame.

[0015] When using this device, the whole machine is driven by the driving vehicle to move to the curb on the side of the bridge. The driving hydraulic cylinder is first controlled to work so that it drives the connecting frame and other components to move downward until the bottom of the connecting frame is stuck on both sides of the curb. Then the output end of the clamping hydraulic cylinder can be controlled to extend and drive the mounting plate to move toward the curb until the roller is against the outer wall of the curb and the spring is deformed to the maximum, so that the spring can force the roller to tightly contact the curb.

[0016] Then the staff puts the materials needed for construction in the transport basket, and then controls the winding motor to drive the winding rod to rotate, so that the winding rope wrapped on the outer wall of the winding rod can be smoothly relaxed and lengthened, and then the transport basket drives the materials to move downward. When the transport basket moves downward to the target height, the driving motor is controlled to drive the driving screw to rotate, and the rotating driving screw can drive the connecting tube and the sliding plate to slide relative to the guide frame through the threaded structure, thereby adjusting the horizontal position of the transport basket, and then moving the transport basket to the target position for the bridge bottom construction personnel to carry out material collection operations.

[0017] At the same time, the drive vehicle can be controlled to drive the whole machine to move, so that the whole machine can move synchronously with the staff's suspension platform in the later stage of construction, which is convenient for construction workers to take materials in time.

[0018] Compared with the related art, the material transportation equipment for bridge bottom surface construction provided by the utility model has the following beneficial effects:

[0019] The utility model provides a transport component, so that workers can place materials on the transport basket, and then control the transport basket to move vertically and horizontally, so that workers located on the hanging basket or platform at the bottom of the bridge can more conveniently take the materials in the transport basket;

[0020] The utility model can improve the running stability of the whole machine by respectively pressing the rollers on both sides of the bridge curbstone, and prevent the danger of the whole vehicle tipping over due to excessive counterweight of the transport basket.
