Improved multipurpose bridge and road construction device

Abstract

The invention discloses an improved multipurpose bridge and road construction device, and belongs to the field of bridge and road construction devices. The improved multi-purpose bridge and road construction device comprises a moving seat, an output shaft of a first motor penetrates through the inner wall of a case and the outer wall of a protection box to extend into the interior and is sleeved with two rotating wheels in a front-back structure, a position changing plate is arranged in the middle of the moving seat, two first cams are symmetrically and fixedly arranged in the middle of the upper side of the position changing plate, an output shaft of the second motor penetrates through the interior of the square cavity, extends into the cylindrical cavity and is sleeved with a first gear, and a tamping block is arranged at the lower end of a sleeve. Through cooperation of the structures, when the device is used, the tamping block can move in the left-right direction through rotation of a rotating wheel in cooperation, tamping work of a regional road surface is conducted, the action area of the device is enlarged, the tamping efficiency is improved, certain time intervals exist, the situation that external follow-up movement is needed every time for matched tamping is avoided, and labor force is reduced.

Description

technical field [0001] The invention relates to the field of bridge and road construction devices, more specifically, to an improved multi-purpose bridge and road construction device. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. Roadbed engineering: Roadbed is a linear structure built with soil or stone. It bears its own weight of rock and soil and the gravity of the road surface, as well as the driving load transmitted by the road surface, and is an important part of the entire road structure. Pavement engineering: Pavement is a layered structure that is layered on the roadbed with various road-building materials or mixtures for vehicles to drive. Its function is to ensure that the car can run all-weather, stable, high-speed, comfortable, safe and economical on the road. In the maintenance construction of bridges and roads, it is necessary t...

Problems solved by technology

The prior art publication No. CN108221584A provides an improved multi-purpose bridge and road construction device. The device is provided with a groove in the bottom wall of the sliding cavity, and the sliding cavity is slidingly fitted to connect the sliding frame body. The bottom end surface of the sliding frame body is A first sliding chamber is provided inside, a second sliding chamber is provided in the top end surface of the sliding frame body, first through grooves are respectively penetrating through the inner walls on the left and right sides of the first sliding chamber, and the first through grooves on the left and right sides are opposite to each other in the first sliding chamber The top pressure cam is connected with the transition fit, and the rotation shaft extending left and right is fixed on the top pressure cam. The second sliding cavity is transition fit and connected with the second protrusion, and the second protrusion is provided for dynamic connection with the first rack Lifting and tamping, although the device has more beneficial effects, there are still the following problems: the device is equipped with a tamping plate for operation, and its active area is small, which reduces the efficiency of tamping. It is cumbersome and increases the labor force. In view of this, we propose an improved multi-purpose bridge and road construction device
