[0002] At present, when there is no traffic requirement on the top of a concrete dam, the width of the dam top shall not be less than 2 meters. The related projects and facilities on the top of the dam include the top of the dam, wave-breaking walls, curbstones, railings and lighting equipment.

[0003] When pouring concrete on the dam top or constructing other facilities, a winch is needed as an auxiliary equipment. During the transportation of concrete on the dam top, the winch transports the concrete to the dam top. At the same time, the winch cooperates with the concrete truss plastering machine to construct the concrete surface. When the winch is installed, the winch base and the fixed point are fixed with punched bolts. The displacement installation of the winch is cumbersome. Workers install the winch on the dam top to cooperate with the construction of the dam top, and transport the materials and equipment needed for the dam top construction, thereby improving construction efficiency.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there is a defect that it takes a long time to reposition the winch after it is positioned, and the construction period of the workers cooperating with the winch on the dam top is forced to be extended, resulting in an extension of the construction period of the entire dam top. Summary of the invention

[0005] In order to improve the defect that it takes a long time to reposition the winch after displacement, which forces workers to cooperate with the dam top construction through the winch to extend the construction period of the entire dam top, the present application provides a dam top bidirectional movable hydraulic traction trolley.

[0006] The present application provides a dam top bidirectional movable hydraulic traction trolley adopts the following technical solution:

[0007] A bidirectionally movable hydraulic traction trolley on a dam top comprises a vehicle plate, an electric winch is fixedly arranged on the vehicle plate, a traveling assembly for the vehicle plate to move is arranged on the vehicle plate, a plurality of traveling assemblies are arranged, the traveling assembly comprises a fixed bracket and a driving wheel, one end of the fixed bracket is fixedly connected to the vehicle plate, and the other end is cantilevered in a direction away from the vehicle plate, the driving wheel is rotatably connected to the fixed bracket, the driving wheel is located at one end of the cantilevered fixed bracket, the driving wheel rotates relative to the fixed bracket, a driving assembly for the driving wheel to rotate is arranged on the vehicle plate, the number of driving assemblies is the same as the number of traveling assemblies, and an electrical control cabinet for opening or closing the electric winch is fixedly arranged on the vehicle plate.

[0008] By adopting the above technical solution, the electric winch is fixed on the vehicle plate. When the electric winch needs to be displaced, the driving assembly provides power to the traveling assembly to start the operation of the traveling assembly, that is, the driving wheel rotates to drive the vehicle plate to move, so that the electric winch only needs to be fixed to the vehicle plate once. After that, the displacement of the electric winch during construction is realized by the driving assembly and the traveling assembly, and the opening and closing of the electric winch is controlled by the electrical control cabinet, so that the electric winch can be displaced again simply and quickly after positioning, thereby saving construction time.

[0009] Optionally, the drive assembly includes an electric hydraulic cylinder and a crankshaft connecting rod, one end of the electric hydraulic cylinder body is fixedly connected to the vehicle plate, one end of the electric hydraulic cylinder piston cylinder is hinged to one end of the crankshaft connecting rod, the hinge axis is horizontally arranged and perpendicular to the travel direction of the drive wheel, and the crankshaft connecting rod is rotatably connected to the side wall of the drive wheel away from the electric hydraulic cylinder.

[0010] By adopting the above technical solution, the piston rod of the electric hydraulic cylinder at one end of the vehicle plate is extended, and the piston rod of the electric hydraulic cylinder at the other end of the vehicle plate is retracted, and then the electric hydraulic cylinders at both ends of the vehicle plate operate in the opposite direction, and such reciprocating motion causes the drive wheel to start rotating, thereby realizing the movement of the vehicle plate.

[0011] Optionally, four walking components are provided and distributed at four positions of the vehicle plate, the horizontal projection connecting line of the four walking components is rectangular, walking wheels are fixedly provided at the bottom of the vehicle plate, and a track is fixedly provided at the top of the dam top. Two tracks are provided, and adjacent tracks are arranged in parallel. Multiple walking wheels are provided, and adjacent walking wheels are equidistantly distributed along the length direction of the track. The walking wheels and the driving wheels are both located on the track and are rollingly connected to the track.

[0012] By adopting the above technical solution, the setting of the track plans the walking route for the running wheels and the driving wheels, making the movement of the vehicle plate carrying the electric winch more stable. The weight borne by the middle part of the vehicle plate is transferred to the track through multiple running wheels, that is, the setting of the running wheels increases the load-bearing capacity of the vehicle plate.

[0013] Optionally, the vehicle plate is fixedly provided with electric rail clamps for locking the vehicle plate and the track, and the number of the electric rail clamps is the same as the number of the tracks.

[0014] By adopting the above technical solution, the electric rail clamp is automatically opened when the vehicle plate is moving, and is automatically clamped to the track in other states, thereby preventing the vehicle plate from sliding when subjected to unexpected thrust.

[0015] Optionally, a counterweight box is fixedly installed on the vehicle plate, and a partition is arranged inside the counterweight box. The partition is arranged vertically and divides the counterweight box into a first chamber and a second chamber. A lifting component for lifting objects inside the second chamber is arranged at the bottom of the second chamber.

[0016] By adopting the above technical solution, the partition divides the counterweight box into two chambers. Heavy objects used for counterweight are placed in the first chamber to achieve the effect of counterweighting the vehicle plate. Some small equipment or construction materials used for construction are placed in the second chamber to avoid secondary transportation and save construction time. The jacking assembly makes it easy for construction workers to take out the items in the second chamber.

[0017] Optionally, the lifting assembly includes a first cylinder and a push plate, the push plate is located above the first cylinder, the push plate is close to the side wall of the second chamber and abuts against the inner wall of the second chamber, the first cylinder is vertically arranged, one end of the first cylinder body is fixedly connected to the bottom inner wall of the counterweight box, and the first cylinder piston rod is fixedly connected to the push plate.

[0018] By adopting the above technical solution, when the items in the second chamber are taken out again, the items located near the opening of the second chamber can be easily taken out, while the items located at the bottom of the second chamber are inconvenient to be taken out. At this time, the piston rod of the first cylinder starts to move as a piston, thereby lifting the push plate upward, and the push plate pushes the items in the second chamber toward the opening of the second chamber, thereby making it easier for construction workers to take the items away.

[0019] Optionally, a limit assembly is provided on the top surface of the vehicle plate, and two limit assemblies are provided. Adjacent limit assemblies are located on both sides of the electric winch. The limit assembly includes a first fixed plate, a second fixed plate, a first screw and a first pressure plate. One end of the first fixed plate is fixedly connected to the vehicle plate and is arranged perpendicular to the vehicle plate, and the other end is fixedly connected to one end of the second fixed plate. The second fixed plate is arranged perpendicularly to the first fixed plate, and the second fixed plate is cantilevered away from one end of the first fixed plate toward the direction close to the electric winch. The first pressure plate is located between the vehicle plate and the second fixed plate, and the first screw thread penetrates the second fixed plate and is fixedly connected to the first pressure plate. The setting direction of the first screw is parallel to the first fixed plate, and the first pressure plate abuts against the top surface of the electric winch base on the side facing away from the first screw.

[0020] By adopting the above technical solution, when the electric winch is fixed to the vehicle plate, the electric winch is placed between adjacent first fixing plates, and then the first pressure plate is gradually pressed against the top surface of the electric winch base by rotating the first screw, so that the first pressure plate cooperates with the vehicle plate to clamp and fix the electric winch base, thereby achieving the effect of quickly fixing the electric winch on the vehicle plate and saving construction time.

[0021] Optionally, a slideway is provided on the top surface of the vehicle plate for the limit assembly to slide and cannot leave the vehicle plate, a second screw is provided between adjacent limit assemblies, the second screw is horizontally and arranged in the length direction of the slideway, one end of the second screw is threaded through any first fixed plate and then rotatably connected to the other first fixed plate, the second screw abuts against the side wall of the electric winch base away from the counterweight box, a third fixed plate is provided on the side wall of the counterweight box close to the electric winch, a distance adjusting assembly is provided on the counterweight box for the third fixed plate to move away from or close to the electric winch, the third fixed plate is horizontally arranged, one end of the third fixed plate is fixedly connected to the distance adjusting assembly, and the other end is cantilevered in the direction away from the counterweight box, a third screw and a second pressure plate are provided on the third fixed plate, the second pressure plate is located between the third fixed plate and the vehicle plate, one end of the third screw is vertically threaded through the third fixed plate and then rotatably connected to the second pressure plate, and the side wall of the second pressure plate facing away from the third fixed plate abuts against the top surface of the electric winch base.

[0022] By adopting the above technical scheme, the opening of the slideway plans a sliding path for the sliding of the limit assembly, making the sliding of the limit assembly more stable. When the electric winch is placed between adjacent limit assemblies, the second screw is rotated to make the adjacent first fixed plates move towards each other, and then the adjacent first fixed plates clamp the electric winch base to adapt to winch bases of different sizes. The third screw is rotated to make the second pressure plate away from the side wall of the third fixed plate and press against the top surface of the electric winch base, so that the second pressure plate cooperates with the vehicle plate to clamp and fix one end of the electric winch base. At this time, in the same horizontal plane, the adjacent limit assemblies limit one horizontal direction of the electric winch, and the second screw cooperates with the second pressure plate to limit the other horizontal direction of the electric winch, thereby replacing the method of opening screw holes on the vehicle plate and fixing the electric winch with bolts, and achieving the effect of quickly fixing the electric winch.

[0023] Optionally, adjacent first fixed plates are each provided with a stopper, which is fixed on the side wall opposite to the adjacent first fixed plates, and is located between the first screw and the electric winch base. The stopper abuts against the vertical side wall of the electric winch base close to the first screw, and a gap is left between the stopper and the first screw.

[0024] By adopting the above technical solution, the baffle replaces the first screw to limit the vertical side wall of the electric winch close to one end of the first screw, so that the first screw can be rotated more easily and the operation is more convenient.

[0025] Optionally, the distance adjustment assembly includes a second cylinder and a receiving plate, one end of the second cylinder body is fixedly connected to the outer wall of the counterweight box close to the electric winch, the second cylinder is horizontally arranged, one end of the second cylinder piston rod is fixedly connected to the receiving plate, the receiving plate is vertically arranged, one end of the third fixed plate is fixedly connected to the side wall of the receiving plate close to the electric winch, and when the second pressure plate turns away from the side wall of the third fixed plate and abuts against the top surface of the electric winch base, the receiving plate turns away from the side wall of the counterweight box and abuts against the vertical side wall of the electric winch base.

[0026] By adopting the above technical solution, the second cylinder is started, so that the receiving plate drives the third fixed plate and the second pressure plate to move toward the base of the electric winch, and finally the receiving plate abuts against the vertical side wall of the electric winch close to the receiving plate, thereby improving the fixing and limiting effect of the electric winch, and at the same time being able to adapt to the fixation of winch bases of different sizes within a small range.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

Traveling components 3 and driving components 4 for the travel of the car plate 1 are arranged at both ends of the car plate 1. The number of driving components 4 is the same as the number of traveling components 3. After the electric winch 2 is fixed on the car plate 1, the electric winch 2 is controlled to work or stop working by the electrical control cabinet 11. When the electric winch 2 needs to follow the displacement of the construction site, the driving component 4 provides power for the traveling component 3, and then the traveling component 3 drives the car plate 1 to move, so that the electric winch 2 can be simply and quickly displaced again after positioning, thereby saving construction time.
