[0022] The technical scheme of the utility model is described in further detail below through specific embodiments.

[0023] As Figures 1-4 Shown, the utility model discloses movable hydraulic support pin shaft carrying equipment including car body 1 and folding arm crane 2, the car body 1 adopts the form of carrying trolley, for driving the relevant structure (such as folding arm crane 2 etc.) and workpiece (such as pin shaft etc.) on car body 1 and moves;The folding arm crane 2 adopts the form of foldable cantilever, for hoisting pin shaft or other workpieces to car body 1 or carrying down from car body 1, that is, assisting manual feeding and discharging.

[0024] The vehicle body 1 adopts the form of a carrying trolley, and is provided with a walking mechanism 11 and a transportation platform 12. The walking mechanism 11 enables the vehicle body 1 to move on the road surface. The transportation platform 12 is used for loading pins or other workpieces that need to be transported. A workpiece-specific tool holder tray can be arranged on the transportation platform 12. The tool holder tray is adapted to pins or other workpieces, and is used to enable the transportation platform 12 to stably load more pins or other workpieces at a time, so as to increase the carrying capacity of the vehicle body 1. The vehicle body 1 is further provided with a stand column 13. The folding arm crane 2 is arranged on the stand column 13.

[0025] The folding arm crane 2 adopts a foldable cantilever form, and includes a main cantilever 21 and a secondary cantilever 22. The main cantilever 21 and the secondary cantilever 22 are both perpendicular to the stand column 13. Specifically, the main cantilever 21 is perpendicular to and intersects with the stand column 13. The secondary cantilever 22 is perpendicular to the stand column 13. The main cantilever 21 intersects with the secondary cantilever 22. Specifically, one end of the main cantilever 21 is rotationally connected to the stand column 13. The other end of the main cantilever 21 is rotationally connected to one end of the secondary cantilever 22. The other end of the secondary cantilever 22 is provided with a hoist 23. That is, the main cantilever 21 rotates around the stand column 13. The secondary cantilever 22 rotates around the main cantilever 21. The hoist 23 can adopt a power-assisted hoist. The hoist 23 can adopt a power-assisted hoist with a suspension function and a stepless speed regulation function. A worker can work with one hand, and there is no heavy physical burden. The labor intensity of the worker is reduced.

[0026] The folding arm crane 2 is foldable. Specifically, the main cantilever 21 intersects with the secondary cantilever 22. There is an included angle between the main cantilever 21 and the secondary cantilever 22. The process that the included angle between the main cantilever 21 and the secondary cantilever 22 becomes smaller is the folding process of the folding arm crane 2. The process that the included angle between the main cantilever 21 and the secondary cantilever 22 becomes larger is the unfolding process of the folding arm crane 2. When the included angle between the main cantilever 21 and the secondary cantilever 22 is 180 degrees, the main cantilever 21 and the secondary cantilever 22 are completely unfolded.

[0027] The folding arm crane 2 is rotatable. Specifically, the hoist 23 can rotate around the stand column 13 along with the rotation of the main cantilever 21 on the stand column 13.

[0028] According to the above, the process that the hoist 23 approaches the stand column is the folding process of the folding arm crane 2. The process that the hoist 23 moves away from the stand column is the unfolding process of the folding arm crane 2. The process that the hoist 23 rotates around the stand column 13 is the rotation process of the folding arm crane 2.

[0029] When the main cantilever 21 rotates on the column 13 and the secondary cantilever 22 rotates on the main cantilever 21, the crane 23 can move to the upper side area of the transport platform 12 and can move out of the range of the upper side area of the vehicle body 1 with the rotation of the main cantilever 21 and the secondary cantilever 22, and the crane 23 can smoothly assist the loading and unloading during this period. In practical application, the folding arm crane 2 has a rotation angle of 360 degrees and a folding angle close to 360 degrees, so it can cover an area with the vehicle body as the center and a radius of several meters (the total length of the main cantilever 21 and the secondary cantilever 22), thereby solving the transportation of workpieces such as pins within the range; in this way, the crane 23 can vertically drop or be lifted when moving to the upper side area of the transport platform 12 or moving out of the range of the upper side area of the vehicle body 1, that is, the transportation of workpieces such as pins is completed vertically, avoiding the risk of workpiece suspension.

[0030] The rotation, folding and unfolding of the folding arm crane 2 mainly rely on the rotation shaft, and bearings can be arranged on the rotation shaft for cooperation; specifically, the end of the main cantilever 21 is provided with a main cantilever rotation shaft perpendicular to the main cantilever 21, and the main cantilever rotation shaft is in bearing cooperation with the column 13; the end of the secondary cantilever 22 is provided with a secondary cantilever rotation shaft perpendicular to the secondary cantilever 22, and the secondary cantilever rotation shaft is in bearing cooperation with the main cantilever 21.

[0031] If loading and unloading is needed, the crane 23 can be manually pulled to move with the rotation of the main cantilever 21 and the secondary cantilever 22, thereby completing the rotation and folding of the folding arm crane 2; of course, a motor-driven electric adjustment scheme can also be used, that is, a motor is used to control the rotation of the main cantilever 21 and the secondary cantilever 22, and the motor control is a prior art which will not be described here.

[0032] As shown in Figure 3 , the movement path of the crane 23 when the main cantilever 21 and the secondary cantilever 22 rotate sweeps through the upper side area of the transport platform 12 and forms coverage of the upper side area, so that there is no transportation blind area on the upper side of the transport platform 12, and the components such as the lifting rope on the crane 23 vertically drop or rise outside the transport platform 12, that is, the transportation of workpieces such as pins is completed vertically, avoiding the risk of workpiece suspension; specifically, when the included angle between the main cantilever 21 and the secondary cantilever 22 is 180 degrees (that is, they are parallel and do not overlap), the end of the secondary cantilever 22 away from the column 13 (that is, the end provided with the crane 23) forms a circumferential area when rotating around the column 13, and the circumferential area includes the upper side area of the transport platform 12; in this way, the movement path of the crane 23 can form coverage of the upper side area of the transport platform 12.

[0033] Based on the above, the angle between the main cantilever 21 and the auxiliary cantilever 22 is 180 degrees, and the main cantilever 21 rotates around the column 13, the movement path of the hoisting machine 23 is outside the upper side area of the vehicle body 1, so that the hoisting operation can be completed within the 360-degree rotation angle range of the folding arm crane 2, thereby expanding the carrying range of the folding arm crane 2, and the hoisting machine 23 can perform vertical falling or rising in the area outside the upper side area of the vehicle body 1, that is, the workpiece such as the pin shaft can be carried vertically upward and downward.

[0034] As shown in Figure 2 , the traveling mechanism 11 includes a rudder wheel 111 and a load wheel 112, and the vehicle body 1 is also provided with a storage battery 14 for driving the traveling mechanism 11 to supply power; the rudder wheel 111 can adopt a rudder wheel with steering and driving functions, and the load wheel 112 can adopt a universal wheel, and a control panel corresponding to the traveling mechanism 11 is provided on the vehicle body 1, which is convenient for manual operation and control of the vehicle body 1 to travel. Further, the vehicle body 1 can adopt a four-wheel structure of four load wheels, and the rudder wheel 111 is arranged between the four load wheels 112, and the four load wheel structure makes the vehicle body 1 more stable and less likely to fall during carrying.

[0035] Based on the above, the storage battery 14 and the transportation platform 12 are arranged on both sides of the column 13, and the column 13 can be closer to the storage battery 14, and the area of the vehicle body 1 occupied by the storage battery 14 is smaller than the area of the vehicle body 1 occupied by the transportation platform 12, so that the weight of the vehicle body 1 during use of the folding arm crane 2 to carry workpieces can be balanced, and the vehicle body 1 is less likely to fall during carrying.

[0036] As shown in Figure 2 , the vehicle body 1 includes a bottom frame 15, the traveling mechanism 11 is arranged at the bottom end of the bottom frame 15, and the transportation platform 12, the column 13 and the storage battery 14 are arranged at the upper end of the bottom frame 15; the bottom frame 15 can enhance the overall structural strength of the vehicle body 1, so that the vehicle body 1 can achieve greater load capacity; in actual application, thanks to the related structures of the vehicle body 1, the load capacity of the vehicle body 1 can reach more than 3 tons.

[0037] As shown in Figure 1 , the vehicle body 1 further includes a vehicle body compartment 16 arranged at the upper end of the bottom frame 15, the transportation platform 12 is arranged outside the vehicle body compartment 16, the bottom of the column 13 and the storage battery 14 are arranged inside the vehicle body compartment 16, and the control panel of the traveling mechanism 11 can be arranged on the vehicle body compartment 16; the vehicle body compartment 16 can protect the storage battery 14 and other related structures (such as circuits) on the vehicle body 1, to prevent damage to the storage battery 14 and other related structures caused by bumping during carrying of workpieces such as pin shafts; the vehicle body compartment 16 is also used to support the column 13, and in addition to the direct connection between the bottom end of the column 13 and the bottom frame 15, the column body of the column 13 can also be connected with the vehicle body compartment 16 to be supported by the vehicle body compartment 16.

[0038] The movable hydraulic support pin shaft carrying equipment of the utility model, the folding arm crane 2 equipment is installed on the vehicle body 1, can rotate 360 DEG, can cover the area of the vehicle body 1 as center radius several meters, to solve the carrying problem of pin shaft and other workpieces in the area, and the carrying of pin shaft and other workpieces can be completed straight up and straight down, avoiding the possible suspension problem of workpieces during carrying; the lifting machine 23 adopts power-assisted lifting cage, has suspension function, stepless speed regulation function, and a worker can work with one hand, and there is no heavy physical burden, reducing the labor intensity of workers; the steering wheel 111 is used as its driving system, and the equipped battery 14 can meet the power supply all day, so specific tooling racks can be carried to every position of the factory, and the flexibility is high.
