[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the embodiments, by Figure 1-4 A transport trolley for intelligent robot transportation is provided, comprising a trolley body 1, a support frame 2 at the top of the trolley body 1, a drive motor 3 fixedly connected to the top of the support frame 2, a lead screw 4 fixedly connected to the output end of the drive motor 3, the lead screw 4 being rotatably connected to the inner side of the support frame 2, a threaded sleeve 5 threadedly connected to the outer side of the lead screw 4, a mounting plate 6 fixedly connected to the front end of the threaded sleeve 5, a clamping mechanism 7 at the front end of the mounting plate 6, a guide mechanism 8 for guiding the mounting plate 6 at the rear end, a bidirectional motor 9 fixedly connected to the inner side of the trolley body 1, drive wheels 10 fixedly connected to the outer sides of both output ends of the bidirectional motor 9, and steering wheels 11 with steering function on the left and right sides of the trolley body 1.

[0022] With the above settings, the bidirectional motor 9 is started and the forward direction is controlled by the steering wheel 11 (the steering wheel 11 is any device that can perform steering function known to those skilled in the art). When the transport trolley reaches the target position, the intelligent robot is clamped by the clamping mechanism 7. Then, the drive motor 3 (the drive motor 3 is a servo motor) is started, and the drive motor 3 drives the lead screw 4 to rotate, thereby causing the threaded sleeve 5, the mounting plate 6 and the clamping mechanism 7 to move upward, lifting the intelligent robot. Then, with the cooperation of the drive wheel 10 and the steering wheel 11, the robot is lifted and moved to the work station. After reaching the work station, the drive motor 3 reverses, causing the threaded sleeve 5, the mounting plate 6 and the clamping mechanism 7 to move downward, slowly lowering the intelligent robot. It should be noted that a counterweight can be placed on the top of the trolley body 1 to prevent the transport trolley from tipping over due to instability. The position of the clamping mechanism 7 can be adjusted with high precision by driving the lead screw 4 through the drive motor 3, which is suitable for the transport work of the intelligent robot. Moreover, it is more stable than the hydraulic system and is not easily affected by the environment. The lead screw 4 and the threaded sleeve 5 can also achieve self-locking through the thread.

[0023] Reference Figure 1-4The clamping mechanism 7 includes a bending plate 71. The bending plate 71 is fixedly connected to the front end of the mounting plate 6. The base 72 is fixedly connected to the top end of the bending plate 71. The clamping motor 73 is fixedly connected to the bottom end of the base 72. The output end of the clamping motor 73 passes through and extends to the top of the base 72. A connecting rod 74 is fixedly connected to the outside of the output end of the clamping motor 73. Clamping rods 75 are hinged to both ends of the connecting rod 74. Four limiting strips 76 are fixedly connected to the rear end of the base 72. Two clamping arms 77 are slidably connected to the outside of the base 72. The two clamping arms 77 are in contact with the four limiting strips 76 respectively.

[0024] With the above structural setup, in the initial state, the clamping motor 73 is in a power-off or standby state, and the two clamping arms 77 are in an open position under the action of gravity or a reset mechanism, reserving space for gripping goods. When the clamping motor 73 starts, its output drives the connecting rod 74 to rotate. The two ends of the connecting rod 74 are hinged to the two clamping rods 75 respectively, converting the rotational motion into planar motion of the clamping rods 75. The clamping rods 75 push the clamping arms 77 to slide along the outside of the base 72. The clamping arms 77 are constrained by four limit bars 76, ensuring that they can only move linearly along a preset track, avoiding skew. As the clamping motor 73 continues to rotate, the clamping arms 77 retract inward along the linear motion trajectory until they contact the surface of the goods and apply a preset pressure. Anti-slip textures or rubber pads can be added to the inner side of the clamping arms 77 to enhance friction. By controlling the current or torque of the clamping motor 73, the clamping force can be dynamically adjusted to avoid damage to fragile goods due to excessive clamping force or slippage due to insufficient clamping force.

[0025] Reference Figure 1-4 The guide mechanism 8 includes a rotating shaft 81. Four rotating shafts 81 are rotatably connected to the inner side of the mounting plate 6. Guide wheels 82 are fixedly connected to the outer sides of the four rotating shafts 81. Guide grooves 83 are opened on both the left and right sides of the support frame 2. The four guide wheels 82 are located in pairs inside the two guide grooves 83.

[0026] With the above structural configuration, when the drive motor 3 is not started, the mounting plate 6 is in its initial position, and the four guide wheels 82 are respectively embedded in the guide grooves 83 on both sides of the support frame 2, forming a four-point contact constraint. At this time, there is no relative movement between the guide wheels 82 and the bottom of the guide grooves 83, ensuring that the mounting plate 6 does not wobble. After the drive motor 3 starts, the lead screw 4 rotates, driving the threaded sleeve 5 to move axially, and the mounting plate 6 rises and falls accordingly. The rotating shaft 81 drives the guide wheels 82 to roll (rather than slide) in the guide grooves 83, significantly reducing frictional resistance (the coefficient of friction can be reduced to 0.01-0.05), making the lifting process smoother. The four guide wheels 82 are distributed in pairs on both sides of the guide grooves 83, forming a symmetrical force system, effectively counteracting the deflection torque generated by uneven load on the mounting plate 6, and preventing jamming.

[0027] Reference Figure 1-4The front end of the mounting plate 6 is fixedly connected to a camera 12.

[0028] With the above-mentioned structural setup, the camera 12 can identify the intelligent robot, thereby enabling the clamping mechanism 7 to clamp the intelligent robot more accurately. The specific identification process and control logic can be implemented with reference to the application document with Chinese Patent Publication No. CN110096057A.
