Embodiment 1

[0023] Embodiment one, such as Figure 1 to Figure 4 shown.

[0024] The quick-start frog-type rammer is mainly composed of a rammer 1, an eccentric block 2, a rammer pulley 3, a belt 4, a pulley 5 and a motor 7. Among them, the handrail 8 and the motor 7 are installed on the bottom plate 9, the bottom plate is a supporting part in contact with the ground, and is connected with the pulley 5 through a belt, and the pulley 5 is connected with the tamper pulley 3 through a belt, so as to realize driving the tamper pulley turn.

[0025] The rammer 1 and the base plate 9 are pivotally connected by a circular shaft 91, and the axis of the circular shaft 91 is coaxially arranged with the pulley, and the rammer pulley 3 is installed on the upper side of the rammer, all of which are prior art. The improvements are:

[0026] On the two sides of the tamper pulley 3 are respectively provided with two slideways symmetrically arranged with respect to the center of the tamper pulley and p...

Embodiment 2

[0030] Embodiment two, such as Figure 6 shown.

[0031] The difference from the first embodiment lies in the installation method and position of the elastic element. Specifically, the elastic element is a compression spring element 63 sleeved on the columnar part and located between the columnar part and the slideway, and a blocking piece 65 is fixed at the end of the columnar part by screws for replacement and maintenance. The spring element 63 compresses the eccentric block and is close to the axis of the rammer pulley.

Abstract

A frog rammer capable of being started and stopped rapidly is used for solving the problems of long time and high energy consumption during starting and stopping of frog rammers. The frog rammer comprises a ramming hammer, an eccentric block, a ramming hammer belt wheel, a belt, a belt wheel, a handrail, a base plate and a drive part. The frog rammer is characterized in that two slides which are arranged symmetrically with the ramming hammer serving as the center and are parallel to each other are arranged on the side of the ramming hammer belt wheel, two columnar parts connected with the eccentric block and capable of sliding linearly along the slides are arranged in the slides, and an elastic element pre-tightening the eccentric block and close the axis of the ramming hammer belt wheel is arranged between the eccentric block and the slides or between the columnar parts and the slides. According to the frog rammer, the eccentric block is movable, as the rammer is close to the rotation center during starting, the generated centrifugal force is small, the eccentric block is away from the rotation center after starting till the centrifugal force meets requirements during the operation, and rapid starting of the rammer is achieved through the process.

Description

technical field [0001] The proposal relates to the technical field of frog ramming machines, in particular to a frog ramming machine which is convenient for quick start and stop. Background technique [0002] At present, the frog-type ramming machine is all made of the principle of rotating inertial force, and is composed of a rammer, a ramming frame, an eccentric block, a pulley and an electric motor. Among them, the eccentric block is directly connected with the belt pulley, and is the core component to realize the ramming action and move forward. And these eccentric blocks are solid blocks, which are relatively heavy, which makes the frog-type ramming machine need to overcome the inertia when starting, and the time to adjust from the static state to the working state is relatively long, the energy loss is large when starting, and most of the eccentric blocks are It is fixed on both sides of the rammer pulley, and in an unbalanced state, there is a high potential safety h...
