Description

Technical Field

[0001] The invention relates to a railway maintenance working device frame, belonging to the technical field of railway maintenance machinery design and manufacturing. Background Art

[0002] When railway maintenance machinery encounters switches, curves, and other sections during railway construction or maintenance, some operations involving the roadbed, rails, sleepers, and fasteners require the movement of the work unit, such as tamping, rail maintenance, sleeper replacement, and fastener installation and maintenance. These movements may include rotation and lateral movement, and the work unit is typically mounted on a frame capable of rotation and lateral movement to achieve this movement. Current rotating and lateral movement frames suffer from being too bulky or having a limited range of motion. Therefore, it is necessary to develop a railway maintenance work device frame with a compact structure and a large range of motion.

[0003] For example, Chinese invention patent publication number CN105658872A discloses a tamping machine with a rotatably mounted working frame, which provides a tamping machine. The tamping machine comprises a machine frame and an assembly frame. The assembly frame is disposed between a track running mechanism and is movable on the track via the running mechanism, and is connected to the machine frame for longitudinal movement via a frame support. A vertically adjustable tamping unit and a track lifting unit are provided between the running mechanism and the frame support. The frame support is connected to the machine frame for pivoting about a support shaft extending longitudinally along the machine. However, the tamping machine still suffers from the disadvantages of a bulky frame structure and a small range of movement. Summary of the Invention

[0004] The present invention provides a railway maintenance work device frame, which meets the needs of working units in different positions and can perform rotational and lateral movements. It has a compact structure, flexible operation and a large movable range, solving the problems of the existing railway maintenance work device frame having a non-compact structure and a small movable range.

[0005] The present invention is achieved through the following technical solutions: a railway maintenance work device frame, which includes an inner rotation and transverse movement device, an outer rotation and transverse movement device, and an operating unit mounting frame. The inner rotation and transverse movement device is externally connected to the outer rotation and transverse movement device, and the inner rotation and transverse movement device and the outer rotation and transverse movement device are respectively connected to the operating unit mounting frame. The inner rotation and transverse movement device includes an inner fixed beam and an inner rotation beam, and the inner fixed beam and the inner rotation beam are connected.

[0006] Preferably, the external rotation and transverse movement device adopts a telescopic arm structure.

[0007] Preferably, the outer rotary transverse moving device is arranged in front of and behind the working position of the inner rotary transverse moving device along the working direction, and at least one outer rotary transverse moving device is arranged on each side of the front and rear.

[0008] Preferably, the inner rotation and transverse movement device includes an inner rotation device and an inner transverse movement device, and the inner transverse movement device is connected to the inner rotation device, and is used to realize rotation and transverse movement respectively.

[0009] Preferably, the inner rotation device includes the inner fixed beam and the inner rotation beam, the inner fixed beam and the inner rotation beam are connected, and the inner rotation beam rotates around the inner fixed beam.

[0010] Preferably, the inner fixed beam and the inner rotating beam are connected via an inner rotating shaft.

[0011] The inner fixed beam is connected to the inner fixed frame, and both the inner fixed beam and the inner fixed frame are connected to the road maintenance machine body, and the inner rotating beam is fixedly connected to the inner rotating frame.

[0012] One end of the inner rotation driving mechanism is connected to the inner rotation beam, and the other end is connected to the inner fixed frame.

[0013] When the inner rotation driving mechanism is activated, the inner rotation beam drives the inner rotation frame to rotate around the inner rotation axis, thereby realizing the rotation action.

[0014] The operating unit mounting frame includes an inner operating unit mounting frame and an outer operating unit mounting frame. The inner operating unit mounting frame is mounted on the inner rotating and traversing device, which enables the operating unit to operate on the inner side of the rail. The outer operating unit mounting frame is mounted on the outer rotating and traversing device, which enables the operating unit to operate on the outer side of the rail and further away.

[0015] The inner transverse movement device includes an inner transverse movement guide column, an inner transverse movement guide sleeve, and an inner transverse movement driving mechanism; the inner transverse movement guide sleeve is installed on the inner transverse movement guide column and can slide along the inner transverse movement guide column; an inner operation unit mounting frame is installed on the inner transverse movement guide sleeve.

[0016] One end of the inner transverse driving mechanism is connected to the inner working unit mounting frame, and the other end is connected to the inner fixed frame. When the inner transverse driving mechanism is activated, it drives the inner working unit mounting frame to move along the inner transverse guide column, thereby realizing the transverse movement.

[0017] The inner lateral guide post is connected to the inner rotating frame, so when the inner rotating frame rotates, the inner lateral guide post also rotates, thereby driving the inner working unit mounting frame to rotate. Therefore, under the simultaneous action of the inner rotation drive mechanism and the inner lateral drive mechanism, the inner working unit mounting frame can perform a rotational and lateral movement.

[0018] The inner working unit mounting frame is used to mount the working unit, thereby realizing the rotation and transverse movement of the working unit.

[0019] The external rotation and transverse movement device includes an external rotation device and an external transverse movement device, which are respectively used to realize rotation and transverse movement.

[0020] The external rotation device includes a first external rotation shaft, a first external rotation driving mechanism, a second external rotation shaft, and a second external rotation driving mechanism.

[0021] The outer traverse device comprises an outer telescopic arm and an outer traverse driving mechanism. The outer telescopic arm comprises a multi-layer guide sleeve structure, thereby being able to perform a telescopic action.

[0022] One end of the outer telescopic arm is connected to the road maintenance machine body via a first outer rotation axis, and the other end is connected to the outer working unit mounting frame via a second outer rotation axis. When the outer lateral drive mechanism is activated, the outer telescopic arm telescopes, thereby driving the outer working unit mounting frame to perform lateral movement. When the first outer rotation drive mechanism is activated, the outer telescopic arm rotates about the first outer rotation axis, thereby rotating the outer working unit mounting frame. When the second outer rotation drive mechanism is activated, the outer working unit mounting frame rotates about the second outer rotation axis, further achieving rotational movement.

[0023] Since the external rotating device has two rotating points, namely the connection point between the first external rotating shaft and the road maintenance machine body and the connection point between the first external rotating shaft and the second external rotating shaft, the rotating action is more flexible.

[0024] Under the simultaneous action of the first outer rotation drive mechanism, the second outer rotation drive mechanism and the outer transverse movement drive mechanism, the outer working unit mounting frame can perform a rotational and transverse movement.

[0025] The external working unit mounting frame is used to mount the working unit, thereby realizing the rotation and transverse movement of the working unit.

[0026] The work unit mounting frame is not limited to a frame form, and can be changed according to the structural characteristics of the installed work unit, and can even be simplified to an installation hanging point or a mounting plate.

[0027] The inner working unit mounting frame and the outer working unit mounting frame preferably adopt a connectable structure. The inner working unit mounting frame and the outer working unit mounting frame are connected or unlocked by an inner and outer working unit mounting frame locking mechanism.

[0028] When the operating unit does not need to perform remote operations, the inner operating unit mounting frame and the outer operating unit mounting frame can be fixedly connected to each other, and the movements are uniformly controlled by the inner rotating and lateral moving device.

[0029] When the operating unit needs to perform remote operation, the inner operating unit mounting frame and the outer operating unit mounting frame are unlocked from each other, the inner operating unit mounting frame is controlled by the inner rotating and lateral movement device, and the outer operating unit mounting frame is controlled by the outer rotating and lateral movement device.

[0030] The inner operation unit mounting frame is preferably installed with two sets for inner side operation, and the outer operation unit mounting frame is preferably installed with two sets for outer side operation.

[0031] The outer telescopic arm preferably adopts a three-stage guide sleeve structure. The more stages are adopted, the farther the distance that the outer end of the outer telescopic arm can reach.

[0032] Preferably, the inner fixing frame includes inner fixing frame guide grooves, and the inner fixing frame guide grooves are preferably arranged at the edge of the inner fixing frame, or more preferably, the inner fixing frame guide grooves are evenly arranged at the four corners of the edge of the inner fixing frame.

[0033] The end of the inner rotating frame is connected to the end of the inner transverse guide column, and the connection point after the end of the inner rotating frame and the end of the inner transverse guide column are connected is overlapped in the guide groove of the fixed frame. When the inner rotation drive mechanism is activated, the inner rotating beam is driven to rotate and the inner rotating frame is driven to rotate, and then the inner transverse guide column is driven to rotate, and then the inner transverse guide sleeve and the inner working unit mounting frame are driven to rotate, thereby realizing the transmission of the rotation action.

[0034] Since the inner rotating frame and the inner transverse guide column are overlapped in the inner fixed frame guide groove, the gravity generated by the working unit, the inner working unit mounting frame, the inner rotating frame, the inner transverse guide column and other components will be mainly transmitted directly to the inner fixed frame through the inner fixed frame guide groove, and then transmitted to the road maintenance machinery body, avoiding the effect of gravity on the inner rotating shaft, improving the force of the entire rotating frame, and increasing reliability and life.

[0035] The railway maintenance work device frame provided by the present invention can meet the needs of working units in different positions, can perform rotational and lateral movements, has a compact structure, flexible operation and a large movable range, and solves the problems of the existing railway maintenance work device frame having a non-compact structure and a small movable range.

[0039] Step S2: The inner rotating device drives the inner operating unit mounting frame to move to realize the rotation action.

[0051] Step P2: The inner transverse movement device drives the inner working unit mounting frame and the outer working unit mounting frame to move, thereby realizing transverse movement;

[0052] Preferably, in step P2, the inner transverse driving mechanism telescopically drives the inner transverse guide sleeve arranged parallel thereto to move along the inner transverse guide post, thereby generating a transverse displacement, and drives the inner working unit mounting frame installed below the inner transverse guide sleeve to move, and simultaneously drives the outer working unit mounting frame to move, thereby completing the transverse movement of the working unit mounting frame;

[0053] Preferably, the outer traverse drive mechanism is adjusted to a floating state and does not function;

[0056] Preferably, in step S2, the end of the inner rotating frame is connected to the end of the inner transverse guide post, and the connection point between the end of the inner rotating frame and the end of the inner transverse guide post is overlapped in the guide groove of the inner fixed frame;

[0088] In this embodiment, it is assumed that the direction extending along the rail is the longitudinal direction, and the direction parallel to the sleeper is the transverse direction.

[0089] Example 1.1: Figures 1 to 3As shown, a railway maintenance work device frame includes an inner rotation and transverse movement device 1, an outer rotation and transverse movement device 2, and a work unit mounting frame 3. The inner rotation and transverse movement device 1 includes an inner rotation device 11 and an inner transverse movement device 12, respectively used to achieve rotation and transverse movement. The outer rotation and transverse movement device 2 includes an outer rotation device 21 and an outer transverse movement device 22, respectively used to achieve rotation and transverse movement.

[0090] like Figure 4 As shown, the inner rotation device 11 includes an inner fixed beam 111, an inner rotating beam 112, an inner rotating shaft 113, an inner fixed frame 114, an inner rotating frame 115, and an inner rotating drive mechanism 116. Both the inner fixed beam 111 and the inner fixed frame 114 are fixed to the vehicle body of the road maintenance machine, while the inner rotating beam 112 is fixedly connected to the inner rotating frame 115. One end of the inner rotating drive mechanism 116 is connected to the inner rotating beam 112, while the other end is connected to the inner fixed frame 114. The inner fixed beam 111 and the inner rotating beam 112 are connected via the inner rotating shaft 113. When the inner rotating drive mechanism 116 is activated, the inner rotating beam 112 drives the inner rotating frame 115 to rotate about the inner rotating shaft 113, thereby achieving a rotational motion.

[0091] The inner transverse movement device 12 includes an inner transverse movement guide column 121, an inner transverse movement guide sleeve 122, and an inner transverse movement drive mechanism 123. The inner transverse movement guide sleeve 122 is installed on the inner transverse movement guide column 121, so that the inner transverse movement guide sleeve 122 can slide along the inner transverse movement guide column 121. The inner operating unit mounting frame 31 is installed on the inner transverse movement guide sleeve 122. One end of the inner transverse movement drive mechanism 123 is connected to the inner operating unit mounting frame 31, and the other end is connected to the inner fixed frame 114. When the inner transverse movement drive mechanism 123 is in action, it drives the inner operating unit mounting frame 31 to move along the inner transverse movement guide column 121, thereby realizing the transverse movement. In this embodiment, two sets of the inner operating unit mounting frame 31 are installed for inner side operation.

[0092] In this embodiment, the inner fixing frame 114 includes inner fixing frame guide grooves, which are preferably arranged at the edge of the inner fixing frame 114 , or more preferably evenly arranged at the four corners of the edge of the inner fixing frame 114 .

[0093] The end of the inner rotating frame 115 is connected to the end of the inner transverse guide column 121, and the connection point after the end of the inner rotating frame 115 is connected to the end of the inner transverse guide column 121 is overlapped in the fixed frame guide groove. When the inner rotation drive mechanism 16 acts, it drives the inner rotating beam 112 to rotate and drives the inner rotating frame 115 to rotate, and then drives the inner transverse guide column 121 to rotate, and then drives the inner transverse guide sleeve 122 and the inner working unit mounting frame 31 to rotate, thereby realizing the transmission of the rotation action.

[0094] Since the inner rotating frame 115 and the inner transverse guide column 121 are overlapped in the inner fixed frame guide groove, the gravity generated by the working unit, the inner working unit mounting frame 31, the inner rotating frame 115 and the inner transverse guide column 121 and other components will be mainly transmitted directly to the inner fixed frame 114 through the inner fixed frame guide groove, and then transmitted to the road maintenance machinery body, avoiding the effect of gravity on the inner rotating shaft 113, improving the force of the entire rotating frame, and improving reliability and life.

[0095] The inner lateral guide post 121 is also interconnected with the inner rotation frame 115. Therefore, when the inner rotation frame 115 rotates, the inner lateral guide post 121 also rotates, thereby driving the rotation of the inner working unit mounting frame 31. Therefore, under the simultaneous action of the inner rotation drive mechanism 116 and the inner lateral drive mechanism 123, the inner working unit mounting frame 31 can generate a rotational and lateral motion. The inner working unit mounting frame 31 is used to mount the working unit, thereby achieving the working unit's rotational and lateral motion.

[0096] like Figure 5 As shown, the outer rotation device 21 includes a first outer rotation shaft 211, a first outer rotation drive mechanism 212, a second outer rotation shaft 213, and a second outer rotation drive mechanism 214. The outer traverse device 22 includes an outer telescopic arm 221 and an outer traverse drive mechanism 222. The outer telescopic arm 221 is composed of a multi-layer guide sleeve structure and can perform telescopic movements.

[0097] One end of the outer telescopic arm 221 is hinged to the road maintenance machine body via the first outer rotation axis 211, and the other end is hinged to the outer working unit mounting frame 32 via the second outer rotation axis 213. When the outer lateral drive mechanism 222 is activated, the outer telescopic arm 221 telescopes, thereby driving the outer working unit mounting frame 32 to move laterally. When the outer rotation drive mechanism 212 is activated, the outer telescopic arm 221 rotates about the first outer rotation axis 211, thereby rotating the outer working unit mounting frame 32. When the second outer rotation drive mechanism 214 is activated, the outer working unit mounting frame 32 rotates about the second outer rotation axis 213, achieving further rotation.

[0098] Because the external rotation mechanism 21 has two rotation points—the first external rotation axis 211 and the second external rotation axis 213—it offers greater rotational flexibility. The first external rotation drive mechanism 212, the second external rotation drive mechanism 214, and the external lateral movement drive mechanism 222 enable the external operating unit mounting frame 32 to perform rotational and lateral movements. The external operating unit mounting frame 32 is used to mount the operating unit, enabling its rotational and lateral movements.

[0099] In this embodiment, two sets of outer operation unit mounting frames 32 are preferably installed for outer operation. The outer telescopic arm 221 preferably adopts a three-stage guide sleeve structure. The more stages are adopted, the farther the outer end of the outer telescopic arm can reach.

[0100] like Figure 2 As shown, in this embodiment, it is preferred to install an inner and outer working unit mounting frame locking mechanism 4 between the inner working unit mounting frame 31 and the outer working unit mounting frame 32, and connect or unlock the inner working unit mounting frame 31 and the outer working unit mounting frame 32 through the inner and outer working unit mounting frame locking mechanism 4. When the working unit does not need to perform remote operations, the inner working unit mounting frame 31 and the outer working unit mounting frame 32 can be fixedly connected to each other, and the movements are uniformly controlled by the inner rotary and transverse movement device 1. When the working unit needs to perform remote operations, the inner working unit mounting frame 31 and the outer working unit mounting frame 32 are unlocked from each other, the inner working unit mounting frame 31 is controlled by the inner rotary and transverse movement device 1, and the outer working unit mounting frame 32 is controlled by the outer rotary and transverse movement device 2. The inner working unit mounting frame 31 and the outer working unit mounting frame 32 operate independently without interfering with each other.

[0101] Figure 6 The frame structure diagram of the railway maintenance working device when the external rotating transverse device is extended is given. Figure 7 The structural diagram of the external rotation and transverse movement device in the extended state is given. Figure 6 The outer and inner telescopic arms 221 adopt a three-stage guide sleeve structure. It can be seen that the end of the outer telescopic arm 221 can reach a relatively far distance from the center of the railway maintenance work device frame, thereby realizing the remote operation of the operation unit.

[0102] Figure 8 A structural diagram of a railway maintenance work device frame is provided, with the operating unit being a tamping unit. Each operating unit mounting frame is equipped with a tamping unit. This structure is suitable for tamping operations in turnout areas and can also be used to tamp the trackbed at curved rails.
