Description

Technical Field

[0001] This utility model relates to the field of soft soil reinforcement technology, and more specifically, to an auxiliary device for reinforcing railway sections crossing soft soil foundations. Background Technology

[0002] As a major national transportation artery, the stability and durability of railway lines are directly related to transportation safety and efficiency. In railway construction and maintenance, crossing widely distributed soft soil foundation sections has always been a major technical challenge. Effective reinforcement of soft soil foundation sections is crucial. Conventional reinforcement techniques usually include replacement, drainage consolidation, and composite foundation methods. Among these, when using replacement or layered backfilling techniques, effective compaction of the backfill soil is a key step in ensuring its density and bearing capacity.

[0003] In compaction operations, handheld rammers have significant advantages such as being lightweight, flexible, easy to operate, and adaptable to narrow or complex terrain. However, traditional handheld rammers have a long-standing problem that has plagued on-site construction and urgently needs to be solved: the violent vibrations generated during operation are directly transmitted to the operator's hands and arms through the operating handle, and long-term vibration can easily cause "white finger disease" in operators.

[0004] Therefore, existing reinforcement aids need improvement in terms of their impact on operator hand vibration. Utility Model Content

[0005] In view of the aforementioned problems, and in conjunction with the first aspect of this utility model, an embodiment of this utility model provides an auxiliary device for reinforcing railway sections crossing soft soil foundations, the device comprising:

[0006] An auxiliary device for reinforcing railway sections crossing soft soil foundations includes a base plate, a mounting frame, and a motor. The mounting frame is provided on the top of the base plate, and the motor is installed on the top of the mounting frame. Two sets of mounting frames are provided on the top of the base plate, and a first spring damper is provided in each of the two sets of mounting frames. A shock absorption component is provided on the top of each of the two sets of first spring dampers.

[0007] The motor is provided with a first pulley at one end, the base plate is provided with two sets of bearing seats at the top, and a rotating shaft is provided between the two sets of bearing seats. A second pulley and a third pulley are sleeved on the rotating shaft, and a tamping hammer and an eccentric wheel are provided at one end of the base plate.

[0008] According to a preferred embodiment, both sets of mounting frames are detachably connected to the top of the base plate by bolts, and limit grooves are provided on both sides of both sets of mounting frames. The bottom of both sets of first spring dampers is connected to the base plate.

[0009] According to a preferred embodiment, the shock absorption assembly includes a mounting plate, the top of the mounting plate is provided with two sets of slide rails, the top of each set of slide rails is provided with a slidable slider, the top of each set of sliders is provided with a connecting ring, each set of connecting rings is provided with a connecting plate on one side, and each set of connecting plates is rotatably connected to a second spring damper on one side.

[0010] According to a preferred embodiment, a horizontal plate is provided on the top of the mounting plate, and multiple sets of connecting rods are fixedly connected to the bottom of the horizontal plate. The bottom of each set of connecting rods is connected to the mounting plate. A connecting member is sleeved on one set of connecting rods, and the two sides of the connecting member are respectively rotatably connected to two sets of spring damping.

[0011] According to a preferred embodiment, each of the two sets of connecting rings is provided with a limiting rod, and the two ends of the two sets of limiting rods are respectively inserted into two sets of limiting grooves;

[0012] A pusher is fixedly connected to the top of the horizontal plate.

[0013] According to a preferred embodiment, the first pulley is sleeved on the main shaft of the motor;

[0014] Two sets of mounting platforms are fixedly connected to the top of the base plate, and the bearing seats are installed on the top of both sets of mounting platforms.

[0015] According to a preferred embodiment, one end of the tamping hammer is rotatably connected to the rotating shaft.

[0016] According to a preferred embodiment, a first belt is fitted onto the first pulley and the second pulley, and a second belt is fitted onto the third pulley and the eccentric wheel.

[0017] Based on the above aspects, the embodiments of this application achieve the following:

[0018] First, when using the equipment, the operator can drive the first pulley to rotate via the motor, which in turn drives the second pulley and the shaft to rotate, which in turn drives the third pulley to rotate. Finally, the second belt drives the eccentric wheel to rotate, causing the eccentric wheel to drive the tamping hammer to strike the ground up and down, compacting the area to be worked on. Second, during the tamping process, the first spring damper buffers the vibration transmitted from the base plate to the mounting plate, thereby reducing the transmission of vibration from the equipment to the push frame. At the same time, with the first spring damper buffering the vibration, when the mounting plate moves up and down, two sets of limit rods slide along the limit groove. At this time, the two sets of limit rods move left and right relative to the mounting plate, causing the slider to move left and right along the slide rail. The second spring damper buffers the left and right movement of the slider, further reducing the impact of vibration on the push frame and the operator's hands. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings. Figure 1 This is a structural schematic diagram of an auxiliary device for reinforcing railway sections crossing soft soil foundations, provided by an embodiment of this utility model. Figure 2 This is an exploded view of an auxiliary device for reinforcing railway sections crossing soft soil foundations, provided in an embodiment of this utility model.

Figure 4 This is a schematic diagram of the vibration damping component in an auxiliary device for reinforcing railway sections crossing soft soil foundations, provided by an embodiment of this utility model. The following is a detailed description of this auxiliary device for reinforcing railway sections crossing soft soil foundations.

[0026] An auxiliary device for reinforcing railway sections crossing soft soil foundations includes a base plate 100, a mounting frame 101, and a motor 102. The mounting frame 101 is mounted on the top of the base plate 100 and is fixedly connected to the base plate 100 by welding. The motor 102 is mounted on the top of the mounting frame 101 and is fixed to the mounting frame 101 by bolts. The motor 102 is used to provide power to the device. Two sets of mounting frames 103 are provided on the top of the base plate 100. The two sets of mounting frames 103 are symmetrically distributed. A first spring damper 104 is provided in each of the two sets of mounting frames 103. A vibration damping component is provided on the top of each of the two sets of first spring dampers 104. The vibration damping component is tightly connected to the first spring damper 104 and together they reduce the transmission of equipment vibration to the hand-push frame 126.

[0027] A first pulley 105 is mounted on the output shaft at one end of the motor 102. The first pulley 105 is fixed to the output shaft of the motor 102 by a key connection and can rotate with the output shaft. Two sets of bearing seats 106 are mounted on the top of the base plate 100 on one side of the mounting bracket 101. A rotating shaft 107 is positioned between the two sets of bearing seats 106. Both ends of the rotating shaft 107 pass through the two sets of bearing seats 106 respectively and can rotate freely under the support of the bearing seats 106. A second pulley 108 and a third pulley 109 are mounted on the rotating shaft 107. The second pulley 108 and the third pulley 109... All 09 are fixed to the rotating shaft 107 by key connection and rotate synchronously with the rotating shaft 107. One end of the base plate 100 is equipped with a tamping hammer 110 and an eccentric wheel 111. When the eccentric wheel 111 rotates, the eccentric wheel 111 generates a periodically reverse centrifugal force due to the uneven mass distribution. This centrifugal force is transmitted to the tamping hammer 110 through the mechanical linkage, causing the tamping hammer 110 to alternately overcome gravity to impact the ground downwards and be pulled back upwards by the centrifugal force, forming a continuous reciprocating tamping action. Through this action, the soil particles in the soft soil foundation can be squeezed more compactly, ultimately achieving soil compaction.

[0028] Both sets of mounting frames 103 are detachably connected to the top of the base plate 100 by bolts. This connection method facilitates the disassembly and replacement of the mounting frames 103. When the mounting frames 103 are damaged, they can be quickly repaired. Limiting grooves 112 are provided on the inner walls on both sides of the two sets of mounting frames 103. The bottoms of the two sets of first spring dampers 104 are connected to the base plate 100. When the equipment is working, the base plate 100 will generate a certain amount of vibration. The first spring dampers 104 can buffer part of the vibration transmitted from the base plate 100 to the mounting plate 113 when the equipment is working, thereby reducing the vibration transmitted to the push frame 126, and thus reducing the damage to the operator's hands caused by the long-term vibration of the push frame 126, making the operator more comfortable during use.

[0029] The shock absorption assembly includes a mounting plate 113. Two sets of slide rails 114 are provided on both sides of the top of the mounting plate 113. The slide rails 114 are fixed to the mounting plate 113 by bolts. Each set of slide rails 114 has a slider 115 that can slide along the slide rail 114. Each set of sliders 115 has a connecting ring 116 on its top. The connecting ring 116 is fixed to the slider 115 by welding. Each set of connecting rings 116 has a connecting plate 117 on one side. The connecting plate 117 and the connecting ring 116 are integrally formed. Each set of connecting plates 117 has a second spring damper 118 rotatably connected to one side. The end of the second spring damper 118 is connected to the connecting plate 117 by a pin and can rotate at a certain angle.

[0030] A horizontal plate 119 is provided on the top of the mounting plate 113. A pusher 126 is fixedly connected to the top of the horizontal plate 119. The pusher 126 is welded to the horizontal plate 119 to facilitate the operator to push the equipment. Multiple sets of connecting rods 120 are fixedly connected to the bottom of the horizontal plate 119. The multiple sets of connecting rods 120 are evenly distributed at the bottom of the horizontal plate 119. Their tops are welded to the horizontal plate 119, and their bottoms are all connected to the mounting plate 113, which enhances the connection stability between the horizontal plate 119 and the mounting plate 113. One set of connecting rods 120 is fitted with a connector 121. The connector 121 is connected to two sets of connecting rods 120 on each side. The second spring damper 118 is rotatably connected, and its two ends are respectively connected to the connector 121 and the connecting plate 117. The second spring damper 118 can buffer the relative movement between the connecting plate 117 and the connector 121, thereby reducing the amplitude of the slider 115 sliding along the slide rail 114. The amplitude of the limit rod 122 sliding along the limit groove 112 is also reduced, ultimately reducing the amplitude of the up-and-down vibration of the mounting plate 113, thereby reducing the vibration of the equipment transmitted to the push frame 126 and reducing the damage to the operator's hands caused by the long-term vibration of the push frame 126.

[0031] Each of the two sets of connecting rings 116 is provided with a limiting rod 122. The diameter of the limiting rod 122 matches the inner diameter of the connecting ring 116. The two ends of the two sets of limiting rods 122 are respectively inserted into the two sets of limiting grooves 112. The two ends of the limiting rod 122 are in contact with the inner wall of the limiting groove 112. When the limiting rod 122 moves with the connecting ring 116, it can slide along the limiting groove 112. At the same time, the limiting groove 112 restricts the movement of the limiting rod 122.

[0032] A first pulley 105 is fitted on the main shaft of the motor 102. The inner hole of the first pulley 105 is matched with the diameter of the main shaft of the motor 102 and is fixed by interference fit to ensure that the main shaft of the motor 102 can drive the first pulley 105 to rotate synchronously when it rotates, and there will be no relative slippage.

[0033] Two sets of mounting platforms 123 are fixedly connected to the top of the base plate 100. The mounting platforms 123 are connected to the base plate 100 by welding. Each set of mounting platforms 123 is equipped with a bearing seat 106. The bearing seat 106 is fixed to the mounting platform 123 by bolts to ensure that the bearing seat 106 remains stable during the operation of the equipment and provides reliable support for the rotating shaft 107.

[0034] One end of the tamping hammer 110 is rotatably connected to the rotating shaft 107, and the other end is connected to the eccentric part.

[0035] A first belt 124 is fitted onto the first pulley 105 and the second pulley 108, and a second belt 125 is fitted onto the third pulley 109 and the eccentric wheel 111. The specifications of the second belt 125 are the same as those of the first belt 124, and it can also stably transmit power, so that the rotation of the third pulley 109 can drive the eccentric wheel 111 to rotate synchronously.

[0036] The specific usage and function of this embodiment are explained below:

[0037] When using the equipment, the operator can start the motor 102. The motor 102 drives the first pulley 105 to rotate. The first pulley 105 drives the second pulley 108 to rotate via the first belt 124. The rotation of the second pulley 108 in turn drives the rotating shaft 107 to rotate. The rotation of the rotating shaft 107 simultaneously drives the third pulley 109 to rotate. The third pulley 109 drives the eccentric wheel 111 to rotate via the second belt 125. The rotation of the eccentric wheel 111 causes the tamping hammer 110 to strike the ground up and down, compacting the soft soil foundation area to be constructed, making the soil denser, and improving the stability of the foundation. During the tamping process, the equipment will generate considerable vibration. The first spring damper 104... The vibration transmitted from the base plate 100 to the mounting plate 113 is buffered, thereby reducing the transmission of vibration of the equipment to the push frame 126. At the same time, the mounting plate 113 will move up and down under the buffering effect of the first spring damper 104. At this time, the two sets of limit rods 122 will slide along the limit slide groove 112. The two sets of limit rods 122 will move left and right relative to the mounting plate 113, thereby driving the slider 115 to move left and right along the slide rail 114. The second spring damper 118 will buffer the left and right movement of the slider 115, further reducing the impact of vibration on the push frame 126, reducing the impact of vibration on the operator's hands, and reducing the discomfort of the operator's hands when operating the equipment for a long time.
