Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, and in particular to a portable concrete vibrating device for civil engineering construction. Background Art

[0002] Concrete vibration technology is an important part of construction projects to improve the density and strength of concrete. Its purpose is to expel the air inside the concrete through vibration, reduce voids and pores, and thus enhance the strength and durability of concrete. This technology directly affects the stability and service life of concrete structures. The principle of vibration is based on the mechanical effect of vibration. The water in the concrete is moved through external force vibration to achieve air discharge, particle rearrangement and cohesion enhancement. The vibration method is mainly divided into surface vibration method and internal vibration method. The internal vibration method is to insert the vibrating rod into the concrete for vibration, while the surface vibration method is to place the vibrator directly on the concrete surface. Vibration equipment includes vibrators, vibrators and vibrating rods, etc., which need to be reasonably selected according to the specific conditions of the concrete. Concrete vibration technology is widely used in construction projects such as houses, roads, bridges, etc. to ensure the quality of concrete structures.

[0003] Most common vibration devices place the vibrator on the ground to work. When workers need to vibrate other positions, they need to adjust the position of the motor, which is inconvenient to operate. Most existing portable vibration devices are handheld and backpack types. The handheld type requires the worker to hold the vibration motor in his hand, and the backpack type requires the motor to be carried on the back. The vibrating device works by vibration, and none of the existing portable vibrating devices are equipped with a buffer device, especially the backpack type, which is usually heavier than the handheld type. When the equipment is working, the vibration will continuously hit the worker's waist and cause vibration injuries. Moreover, the vibrating rods of the existing vibrating devices are mostly hoses with a certain degree of flexibility. The hoses can protect the formwork and facilitate passing through the steel bar gaps. However, when the vibrating rod wants to be moved to a farther position for vibration, the vibrating rod is too soft and it is inconvenient for the worker to adjust its position. Therefore, a convenient concrete vibrating device for civil construction is proposed. Summary of the invention

[0004] In order to solve the problems that the vibration generated by the existing concrete vibrating device when used portablely can easily cause injuries to workers, and the vibrating pipe of the vibrating equipment is too soft to be convenient to move to a designated position, the present invention provides a portable concrete vibrating device for civil construction.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A portable concrete vibrating device for civil engineering construction, comprising a vibrating motor; the vibrating device also comprises a shoulder strap device, the vibrating motor is fixedly mounted on the shoulder strap device, the vibrating motor is provided with a vibrating device, the shoulder strap device is provided with an adjusting device, the shoulder strap device is provided with a buffer device, a controller is installed on the shoulder strap device, and the controller is electrically connected to the vibrating motor; Preferably, the shoulder strap device includes a back plate, the controller is fixedly mounted on the back plate, a fixing plate is mounted on one side of the back plate, a connecting block is fixedly mounted on the fixing plate close to the back plate, limiting blocks are fixedly mounted on both sides of the connecting block, the connecting block and the limiting blocks are slidably mounted in the back plate, and a shoulder strap is fixedly mounted on the side of the back plate away from the fixing plate.

[0006] Preferably, a connecting groove is formed on one side of the back plate close to the fixing plate, limiting grooves are formed on both sides of the connecting groove, the connecting block is slidably installed in the connecting groove, and the limiting block is slidably installed in the limiting grooves.

[0008] Preferably, a sponge pad is fixedly installed on a side of the back plate away from the fixing plate, and a mounting plate is fixedly installed on a side of the fixing plate away from the back plate.

[0009] Preferably, the vibration device includes a connecting hose, one end of which is fixedly mounted on the vibration motor, a vibration head is fixedly mounted on the end of the connecting hose away from the vibration motor, a first fixing seat is fixedly mounted on the bottom of the vibration motor, and the first fixing seat and the mounting plate are threadedly mounted with the same first fixing bolt.

[0010] Preferably, a first battery block is fixedly mounted on one side of the vibration motor, and the first battery block is electrically connected to the vibration motor.

[0011] Preferably, the adjusting device includes an air pump, a second fixing seat is fixedly mounted on the air pump, the second fixing seat and the mounting plate are threadedly mounted with the same second fixing bolt, a second battery block is fixedly mounted on one side of the air pump, the second battery block is electrically connected to the air pump, and the air pump is electrically connected to the controller.

[0012] Preferably, a connecting pipe is fixedly mounted on the air pump, and an end of the connecting pipe away from the air pump and the connecting hose are covered with a same elastic sleeve.

[0014] Preferably, the buffer device further comprises a rubber ring, and the rubber ring is fixedly installed in the limiting hole.

[0015] The beneficial effects of the present invention are as follows: (a) The present invention ties the connecting pipe and the connecting hose together through an elastic sleeve. When the connecting pipe is not filled with gas, the connecting hose is relatively soft, which is convenient for workers to pass it through the steel bar gap and the formwork. When the area is vibrated, the connecting hose is pulled out and inflated by an air pump. After the connecting pipe is filled with gas, the connecting pipe becomes hard and can form a support. At this time, the end where the connecting hose and the connecting pipe are fixed together is relatively hard, which is convenient for workers to throw it to a farther position for vibration. Before vibration, the connecting pipe is deflated by an air pump.

The sponge pad on the back plate contacts the back, making it more comfortable to carry. The limit holes, connecting blocks, limit fixing rods and threaded covers cooperate to connect the fixing plate with the back plate, thereby separating the back plate carried on the back from the fixing plate. The machine is installed on the fixing plate and then buffered by the buffer device, which can further reduce the damage to workers caused by vibration when the equipment is working.

[0017] (III) The first spring can buffer the front and rear vibrations between the back plate and the fixed plate generated when the equipment on the fixed plate is working. The second spring can buffer the up and down vibrations generated when the equipment on the fixed plate is working. The rubber ring is arranged in the limit hole to flexibly support the limit fixing rod. When the equipment is working, the outer contour of the limit fixing rod vibrates against the inner wall of the limit hole. The rubber ring can reduce the impact between the limit fixing rod and the inner wall of the limit hole. BRIEF DESCRIPTION OF THE DRAWINGS
