The machine system is simple, easy to operate, and easy to maintain.

[0048] refer to Figure 1-Figure 2 The rail-type mobile hoisting equipment includes: a rail flatbed vehicle 100, a guide rail seat 110, and a hoisting machine 200. The rail flatbed vehicle 100 includes a frame 101 and a first wheel assembly; the first wheel assembly includes a plurality of first wheels 102, and the first wheels 102 are suitable for traveling on a railway track 130; the guide rail seat 110 is fixed to the frame 101 in a detachable manner, and a guide rail 120 is provided on the guide rail seat 110; the hoisting machine 200 includes a frame 201, a boom 202, and a second wheel assembly; the boom 202 is arranged on the frame 201 for hoisting operations; the second wheel assembly includes a plurality of second wheels and a second driving source 206; the second wheel is suitable for traveling on the guide rail 120; the second driving source 206 is used to drive the second wheel.

[0049] The rail flatbed trolley 100 is provided with a first wheel assembly, which is suitable for traveling on the railway track 130, and can transport construction materials and equipment during the construction of the existing railway line, and a guide rail seat 110 is fixed on the frame 101 in a detachable manner. The hoist 200 has a boom 202 and a second wheel assembly, which can be used to hoist construction materials and equipment. The second wheel assembly includes a plurality of second wheels and a second driving source 206, which is suitable for traveling and moving on the guide rail 120 of the guide rail seat 110. The hoist 200 can move on the rail flatbed trolley 100, and can realize the loading and unloading of materials on the entire rail flatbed trolley and adjacent rail flatbed trolleys, and its operating range is wider and the efficiency is high. On the other hand, the guide rail seat 110 is fixed on the frame 101 in a detachable manner, and can be disassembled and separated. When not needed, the hoist 200 and the guide rail seat 110 can be disassembled, and will not occupy the rail flatbed for a long time.

[0050] The rail flatbed vehicle 100 has a first wheel assembly, which includes a plurality of first wheels, and the first wheels are suitable for traveling on the railway track 130. The first wheel assembly can be configured with a first driving source to drive the first wheel, and the first driving source can be an electric motor or a hydraulic motor. In another technical solution, the first wheel assembly can also be not configured with any power source and can be dragged and moved by other mobile devices.

[0051] refer to Figure 1A support platform is formed on the frame 101 of the rail flatbed vehicle 100, and the guide rail seat 110 is a planar bracket structure, which is fixed to the frame 101 of the rail flatbed vehicle 100 by bolts. The hoisting machine 200 and the guide rail seat 110 can be disassembled when not needed.

[0052] refer to Figure 3 In one embodiment of the present application, the second wheel assembly includes two front wheels 203 disposed at corresponding positions on both sides of the frame 201, and two rear wheels 204 disposed at corresponding positions on both sides of the frame 201; the second driving source 206 is a hydraulic motor, which is used to drive the two rear wheels 204 to rotate. Driven by the hydraulic motor, the two rear wheels 204 rotate and travel on the guide rail 120 to change the position of the hoisting machine 200 on the rail flatbed vehicle 100, and can flexibly hoist small and medium-sized equipment and materials.

[0053] refer to Figure 4 The two front wheels 203 are mounted on a movable bridge 205, which is hinged to the frame 201. Based on the hinged relationship between the movable bridge 205 and the frame 201, the two front wheels 203 can be adjusted to float up and down around the hinged position between the movable bridge 205 and the frame 201, so that the two front wheels 203 and the two rear wheels 204 are in contact with the guide rail 120. Figure 4 In the structure shown, the hinged position between the movable bridge 205 and the frame 201 is located in the middle of the two front wheels 203. Specifically, the hinged relationship between the movable bridge 205 and the frame 201 allows the movable bridge 205 to rotate relative to the frame 201, so that the two front wheels 203 can be adjusted to float up and down adaptively, so that the two front wheels 203 can keep in contact with the guide rail 120, and the two rear wheels 204 can keep in contact with the guide rail 120, so as to avoid the wheels from being suspended in the air.

[0054] In one embodiment of the present application, the hoisting machine 200 further includes a plurality of hydraulic rail clamps 207. Figure 3 In the structure shown, four hydraulic rail clamps 207 are provided at the bottom of the frame 201, and the four hydraulic rail clamps 207 are located between the two front wheels 203 and the two rear wheels 204, and are arranged near each wheel. The hydraulic rail clamps can be used to prevent the crane from tipping over during operation.

[0055] Further references Figure 5The hydraulic rail clamp 207 includes a bracket 2071, a first rail clamp arm 2072, a second rail clamp arm 2073, and a clamping cylinder 2074. The bracket 2071 is fixedly connected to the frame 201; the first rail clamp arm 2072 and the second rail clamp arm 2073 are hinged on the bracket 2071 and are respectively located on both sides of the guide rail 120; the clamping cylinder 2074 is connected between the first rail clamp arm 2072 and the second rail clamp arm 2073, and is used to drive the first rail clamp arm 2072 and the second rail clamp arm 2073 to clamp or release the guide rail 120. When the hoisting machine 200 moves, each hydraulic rail clamp 207 releases the guide rail 120; when the hoisting machine 200 performs a hoisting operation, each hydraulic rail clamp 207 clamps the guide rail 120 to prevent the hoisting machine from tipping over during operation.

[0056] When the hydraulic rail clamp 207 is required to clamp the guide rail 120, the clamping oil cylinder 2074 contracts, and the first rail clamp arm 2072 and the second rail clamp arm 2073 rotate around their respective hinge positions to approach each other, thereby clamping the guide rail 120 located therebetween. When the hydraulic rail clamp 207 is required to release the guide rail 120, the clamping oil cylinder 2074 extends, and the first rail clamp arm 2072 and the second rail clamp arm 2073 rotate around their respective hinge positions to move away from each other, thereby releasing the guide rail 120 located therebetween.

[0057] Furthermore, the first rail clamping arm 2072 and the second rail clamping arm 2073 are provided with a clamping block 2075 for clamping the guide rail 120, and the clamping block 2075 is installed in a detachable manner. The clamping block 2075 can be designed to be consistent with the shape of the clamping part of the guide rail, so that it is more stable when clamping.

[0058] In the present embodiment, the hoisting machine 200 further includes a plurality of deflection telescopic legs 210, which are arranged on both sides of the frame 201; when the hoisting machine is in operation, the plurality of deflection telescopic legs 210 jointly support the frame to ensure safety.

[0059] refer to Figure 6-Figure 8The deflection telescopic support leg 210 includes: a first telescopic arm 211 and a second telescopic arm 212; the first telescopic arm 211 is laterally fixed on the frame 201, and its end can be extended out of the frame 201 or retracted to the inside of the frame 201 by telescoping; the front end of the second telescopic arm 212 is connected to the end of the first telescopic arm 211, and can be rotated and adjusted to a vertical angle or a predetermined folding angle at the side position of the frame 201; when the second telescopic arm 212 is at the folding angle, the second telescopic arm 212 can move to the outside of the frame 201 or the inside of the frame 201 with the end of the first telescopic arm 211. When the deflection telescopic legs 210 are folded, the second telescopic arm 212 is retracted and rotated to a folded angle, and the first telescopic arm 211 is contracted to move the second telescopic arm 212 to the inside of the frame 201; when multiple deflection telescopic legs 210 support the frame 201, the first telescopic arm 211 is extended to move the second telescopic arm 212 outside the frame 201, and the second telescopic arm 212 is rotated to a vertical angle and supported on the ground by extension.

[0060] Figure 6 The x direction and the y direction are shown in FIG. 2 , wherein the x direction is the driving direction of the wheels (front wheels and rear wheels), that is, the front-rear direction of the frame 201, and the y direction is the lateral direction of the frame 201. Along the driving direction of the wheels (x direction), a pair of deflection telescopic legs 210 are arranged at the front and rear positions of the frame 201.

[0061] In one embodiment of the present application, when the second telescopic arm 212 is located at a predetermined folding angle, the second telescopic arm 212 is in a horizontal state. Therefore, when folded, the second telescopic arm 212 is retracted into the inner side of the frame 201 in a horizontal state.

[0062] exist Figure 6 and Figure 7 In the state shown, the deflected telescopic support leg 210 is in a supporting state, the first telescopic arm 211 is extended, the second telescopic arm 212 is moved outside the frame 201 and is at a vertical angle, and is supported on the ground by extension to support the frame 201.

[0063] When the deflection telescopic outrigger is folded, first, the second telescopic arm 212 is retracted so that its end is out of contact with the ground; after retracting, the second telescopic arm 212 is rotated relative to the first telescopic arm to a predetermined folding angle; when the second telescopic arm 212 is at the folding angle, the first telescopic arm 211 is retracted to move the second telescopic arm 212 to the inside of the frame 201. At this time, the deflection telescopic outrigger is retracted into the inside of the frame and does not occupy the width space. Figure 7 and Figure 8, the second telescopic arm 212 is shown in the schematic diagram of movement. The second telescopic arm 212 retracts upward along the S1 direction, rotates upward along the S2 direction to be adjusted to a predetermined folding angle, and moves to the inner side of the frame 201 along the S3 direction.

[0064] When the multiple deflection telescopic legs 210 support the frame 201, first, the first telescopic arm 211 extends to move the second telescopic arm 212 outside the frame 201, and then the second telescopic arm 212 is rotated relative to the first telescopic arm to a vertical angle; when the second telescopic arm 212 is at a vertical angle, the second telescopic arm 212 is extended and supported on the ground. When the hoisting machine is in operation, the multiple deflection telescopic legs jointly support the frame to ensure safety.

[0065] In the embodiment of the present application, the front end of the second telescopic arm 212 is connected to the end of the first telescopic arm, and can be rotated relative to the first telescopic arm so that the second telescopic arm 212 can be rotated to a vertical angle or a predetermined folding angle at the side of the frame 201. Figure 7 As shown, the second telescopic arm 212 is kept at the side position of the frame 201 when rotating, that is, the second telescopic arm 212 is rotated and adjusted in the vertical plane on the side of the frame 201. Further, a driving element is provided between the first telescopic arm 211 and the second telescopic arm 212 to drive the second telescopic arm 212 to rotate and adjust relative to the first telescopic arm 211.

[0066] In one embodiment of the present application, the first telescopic arm 211 and the second telescopic arm 212 are connected by a rotating cylinder 213, and the rotating cylinder 213 is used to drive the second telescopic arm 212 to rotate and adjust relative to the first telescopic arm 211. It should be noted that the principle of the rotating cylinder is based on the transmission and control of hydraulic pressure. During operation, when the hydraulic oil enters the cylinder, the piston inside the rotating cylinder will be pushed by the hydraulic pressure, and the friction between the piston and the cylinder will generate a rotational torque. Under the action of the hydraulic pressure, the piston and the cylinder will rotate relative to each other. In order to control the rotational movement of the rotating cylinder, a hydraulic valve is usually set to adjust the entry and discharge of the hydraulic oil. By controlling the hydraulic valve, precise control of the rotating cylinder can be achieved.

[0067] In another embodiment of the present application, the first telescopic arm 211 and the second telescopic arm 212 are hinged, and a driving element for driving the second telescopic arm 212 to rotate relative to the first telescopic arm 211 is provided between the first telescopic arm 211 and the second telescopic arm 212. Here, the driving element can be set to various forms of driving devices, such as an electric device, a pneumatic device, and a hydraulic device.

[0068] In one embodiment of the present application, two deflection telescopic legs 210 are arranged on both sides of the frame 201, and the positions of the deflection telescopic legs 210 on both sides correspond to each other to form two pairs of deflection telescopic legs 210; for a pair of deflection telescopic legs 210 located at corresponding positions on both sides, two first telescopic arms 211 include a horizontally placed fixed sleeve 2111 and telescopic parts 2112 located on both sides of the fixed sleeve 2111; the fixed sleeve 2111 is fixed on the frame 201; the telescopic parts 2112 on both sides are sleeved in the fixed sleeve 2111 and can slide and retract relative to the fixed sleeve 2111; first oil cylinders 2113 for driving the telescopic parts 2112 to slide and retract relative to the fixed sleeve 2111 are respectively provided between the telescopic parts 2112 on both sides and the fixed sleeve 2111, thereby forming first telescopic arms 211 on both sides of the fixed sleeve 2111.

[0069] refer to Figure 6 and Figure 8 The fixed sleeve 2111 is fixed to the frame 201 in the horizontal direction (y direction), and the telescopic members 2112 on both sides are slidably sleeved in the fixed sleeve 2111. When the telescopic member 2112 slides in the direction of extending out of the fixed sleeve 2111, the first telescopic arm 211 is extended; when the telescopic member 2112 slides in the direction of entering the fixed sleeve 2111, the first telescopic arm 211 is retracted. Furthermore, the first oil cylinder 2113 corresponds to the telescopic member 2112 one by one, and the first oil cylinder 2113 is arranged between the corresponding telescopic member 2112 and the fixed sleeve 2111 to drive the corresponding telescopic member 2112 to slide and retract relative to the fixed sleeve 2111. In this structure, a pair of deflection telescopic legs located at corresponding positions on both sides share a fixed sleeve 2111, and telescopic members 2112 and first oil cylinders 2113 are arranged on both lateral sides of the fixed sleeve 2111, thereby forming first telescopic arms 211 on both sides of the fixed sleeve 2111.

[0070] Further references Figure 3 Along the driving direction of the wheels (front wheels and rear wheels), a pair of deflection telescopic legs are arranged at the front and rear positions of the frame 201. The two pairs of deflection telescopic legs can jointly support the frame 201. Figure 7 The two pairs of deflected telescopic legs located at the front and rear positions have second telescopic arms 212 that rotate in opposite directions when folded, thereby folding in the opposite direction on the frame.

[0071] Therefore, in an embodiment of the present application, a plurality of deflection telescopic legs are provided on the hoisting machine, and the deflection telescopic legs include: a first telescopic arm and a second telescopic arm; when the deflection telescopic legs are folded, the second telescopic arm retracts and rotates to adjust to the folding angle, and the first telescopic arm contracts to move the second telescopic arm to the inside of the frame; when the plurality of deflection telescopic legs support the frame, the first telescopic arm extends to move the second telescopic arm outside the frame, and the second telescopic arm rotates to adjust to a vertical angle and is supported on the ground by extension. On the one hand, when the hoisting machine is in operation, the plurality of deflection telescopic legs jointly support the frame to ensure safety. On the other hand, when not in operation, the deflection telescopic legs can be retracted into the inside of the frame when folded and will not occupy the width space.
