Description

Technical Field

[0001] The present application relates to the field of road construction technology, and particularly relates to a rammer for road and bridge construction. Background Art

[0002] A rammer is a device used in construction projects, mainly for tamping operations on the ground. The working principle of the rammer is usually that the driving component drives the rammer to rise to a certain height and then releases the rammer. The rammer accelerates downward under its own gravity and the action of the driving component, so that the rammer strikes the ram plate, and then the ram plate tampes the ground.

[0003] During the working process of the rammer, the rammer is usually operated manually for tamping operations. Dust will be generated during the ground tamping process of the rammer, so a dust suppression device is needed to spray water on the ground. The existing dust suppression device is installed on the housing of the rammer by magnetic attraction. However, the rammer will generate vibration during the working process, which reduces the installation stability of the dust suppression device, and the vibration will damage the internal structure of the dust suppression device.

[0004] Regarding the above related technologies, the inventor believes that the dust suppression device is easily affected by the vibration generated during the working process of the rammer, resulting in a decrease in the installation stability of the dust suppression device and damage to its internal structure. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a rammer for road and bridge construction.

[0006] A rammer for road and bridge construction provided by the present application adopts the following technical solutions:

[0007] A rammer for road and bridge construction includes a housing, a tamping mechanism arranged in the housing, a dust suppression device, a connecting component, and a clamping component arranged on the connecting component. The dust suppression device includes a water storage tank, a water spraying component communicated with the water storage tank, and a connecting block arranged on the water storage tank. The connecting component includes a mounting plate, a mounting block slidably connected to the mounting plate, and a shock absorption spring. The shock absorption spring is connected to the mounting block, and the connecting block and the mounting block are detachably connected.

[0008] By adopting the above technical solutions, the water storage tank is connected to the mounting block through the connecting block, and the clamping component mounts the connecting component and the water storage tank on the housing. When the tamping mechanism performs tamping operations, the housing generates vibration, and the shock absorption spring drives the mounting block to slide. The shock absorption spring absorbs the vibration energy, reducing the influence of vibration on the installation stability of the water storage tank and the water spraying component and the safety of the internal structure.

[0009] Preferably, a first limiting chute is formed in the mounting plate. The mounting block is slidably connected to the first limiting chute. A baffle for limiting the sliding of the mounting block is arranged at the opening of the first limiting chute. The two damping springs are arranged on opposite sides of the mounting block, and the ends of the damping springs away from the mounting block are connected to the mounting plate.

[0010] By adopting the above technical solution, when the housing vibrates, the mounting block slides in the first limiting chute. The arrangement of the baffle increases the stability of the sliding connection between the mounting block and the mounting plate, thereby increasing the mounting stability of the water storage tank.

[0011] Preferably, a second limiting chute is formed on the side of the mounting plate away from the mounting block. The clamping assembly includes a driving motor, a bidirectional lead screw arranged in the second limiting chute, a first slider, a second slider, a first clamping plate and a second clamping plate. One end of the bidirectional lead screw is fixedly connected to the transmission shaft of the driving motor, and the other end is rotatably connected to the mounting plate. The first slider and the second slider are both threadedly connected to the bidirectional lead screw and are respectively arranged on both sides of the bidirectional lead screw. The first slider and the second slider are both slidably connected to the second limiting chute. The first slider is connected to the first clamping plate, and the second slider is connected to the second clamping plate.

[0012] By adopting the above technical solution, the driving motor drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the first slider and the second slider to slide in the second limiting chute, so that the first clamping plate and the second clamping plate move in opposite directions, thereby realizing the installation or disassembly of the mounting plate. The installation process is simple and convenient, and the structure of the housing will not be damaged.

[0013] Preferably, anti-slip pads are arranged on both the first clamping plate and the second clamping plate.

[0014] By adopting the above technical solution, the arrangement of the anti-slip pads further increases the mounting stability of the mounting plate, thereby further increasing the mounting stability of the water storage tank.

[0015] Preferably, the water spraying assembly includes a water outlet pipe communicated with the water storage tank, a water outlet pump connected to the water outlet pipe, a water spraying pipe communicated with the water outlet end of the water outlet pump, and a plurality of atomizing nozzles arranged on the water spraying pipe.

[0016] By adopting the above technical solution, the arrangement of the plurality of atomizing nozzles improves the dust-proof effect of the water spraying assembly, thereby reducing the dust generated during the ramming process, and further improving the working environment of the operator.

[0017] Preferably, a water inlet pipe is arranged on the water storage tank, and a sealing cover is threadedly connected to the opening of the water inlet pipe.

[0018] By adopting the above technical solution, the cover protects the water inlet pipe, reduces the phenomenon of dust in the external environment entering the water storage tank, thereby reducing the phenomenon of the atomizing nozzle being blocked, and further improving the working efficiency of the dust suppression device.

[0019] Preferably, a filter barrel is arranged in the water inlet pipe. A clamping block is arranged at the opening of the filter barrel, a clamping groove is formed at the opening of the water inlet pipe, and the clamping block is clamped with the clamping groove.

[0020] By adopting the above technical solution, the filter barrel filters the water entering the water storage tank, thereby removing impurities in the water, further reducing the occurrence of the phenomenon of the atomizing nozzle being blocked, and further improving the working efficiency of the dust suppression device. The arrangement of the clamping block improves the installation and disassembly efficiency of the filter barrel.

[0021] Preferably, a support rod is arranged at the opening of the filter barrel.

[0022] By adopting the above technical solution, the arrangement of the support rod increases the structural strength of the filter barrel, and the arrangement of the support rod facilitates the operator to remove the filter barrel for cleaning or install the filter barrel into the water inlet pipe, thereby improving the installation and disassembly efficiency of the filter barrel.

[0023] In summary, the present application has the following beneficial technical effects:

[0024] 1. The mounting plate is fixed to the housing through the clamping assembly. The water storage tank is connected to the mounting block through the connecting block. The mounting block slides in the first limiting chute and is connected to the damping spring. The damping spring absorbs the vibration generated by the ramming mechanism, thereby improving the connection stability and structural safety of the dust suppression device;

[0025] 2. The filter barrel in the water inlet pipe filters the water entering the water storage tank, thereby reducing the phenomenon of the atomizing nozzle being blocked, and further improving the working efficiency of the dust suppression device. BRIEF DESCRIPTION OF THE DRAWINGS
