Channel 1 112, channel 2 113, and channel 3 114 correspond to communication channel 4 115, channel 5 116, and channel 6 117 respectively. The supporting frame body 101 is provided with horizontal channel 7 118, channel 8 119, and channel 9 120, which are connected through three groups of process holes: channel 4 115 and channel 7 118, channel 5 116 and channel 8 119, channel 6 117 and channel 9 120, respectively. External oil ports are set at the top and end of the frame 101. The top plane is preferably provided with a vertical external hole 121, and the end is preferably provided with a horizontal external hole 122. The vertical external hole 121 and the end external hole 122 are independent external interfaces of channel seven 118, channel eight 119, and channel nine 120, and can be configured and connected according to the position and interface of the external driving element. The first cavity 103 and the second cavity 104 are set on the end side of the chassis frame 1, the guide wheel shaft 105 is set at the bottom of the supporting frame 101, the keyway 109 is set on the upper plane of the supporting frame 101, and the threaded hole 111 connected to the process hole is set on the upper plane of the supporting frame 101.

[0031] like Figure 1 、 Figure 5 As shown, the anti-collision head 2 is arranged in the first cavity 103 , and the photoelectric detection head 3 is arranged in the second cavity 104 .

[0032] like Figure 1-2 , Figure 5 As shown, the guide wheel shaft 105 is installed with bearings to form the guide wheel 4. Preferably, two sets of guide wheels 4 are symmetrically adapted and arranged in the concave track 10. The keyway 109 is equipped with a key for fixing the load 9. The load 9 can be a pallet or a pallet loaded with heavy objects. The threaded hole 111 is installed to install the pressure sensor 8.

[0033] like Figure 4 、 Figure 6 As shown, the upper surface of the sinking plate 110 is used to install and place the power source 16, and the oil input and output ports of the power source 16 are connected to hole 112, hole 2 113, and hole 3 114.

[0034] like Figure 2 、 Figure 5 The shafts of the power wheel shaft 5 and the first driven wheel shaft 6 are respectively equipped with multiple sets of bearings. The power wheel shaft 5 and the first driven wheel shaft 6 are installed in the semicircular shaft groove 107 of the chassis frame 1. The outer circle of the bearing cooperates with the semicircular shaft groove 107. The gear shaft box 11 is buckled and set at the bottom of the chassis frame 1 for storing gear grease and covering the bearing installation section of the power wheel shaft 5 and the first driven wheel shaft 6. The middle section of the power wheel shaft 5 is provided with a middle section gear and exposed in the long groove 102. Figure 10As shown, according to the load size, the wheel axle position of the chassis frame 1 includes at least a first power output wheel axle portion I. When the driving capacity needs to be improved, a second power output wheel axle portion III can be adaptively added. When the load-bearing capacity needs to be further improved, a driven wheel axle portion II is provided between the first power output wheel axle portion I and the second power output wheel axle portion III. The central shaft groove 108 of the driven wheel axle portion II has the function of accommodating a larger number of bearings and accommodating multiple sets of second driven wheel axles 7. The number of bearings installed on the shaft body of the second driven wheel axle 7 is more than that of the power wheel axle 5, which is used to improve the load-bearing capacity. A side plate 12 is connected to the outer side of the chassis frame 1 to limit the second driven wheel axle 7 to prevent axial displacement.

[0035] like Figure 3-8 , a position for accommodating two driving devices is set in the long groove 102, and the driving device can be a motor worm assembly and / or a rack cylinder assembly 15. The rack cylinder assembly 15 is affected by the rack stroke and is suitable for short-distance driving working conditions. The motor worm assembly includes a motor 13 with a flange and a worm 14 connected to the motor output shaft. The flange is set outside the motor body and adapts to the vertical groove 106. The teeth of the worm 14 are engaged with the teeth of the power wheel shaft 5 for transmission. The rack cylinder assembly 15 includes a cylinder and a bidirectional rack piston set in the cylinder. The cylinder is set Corresponding to the opening in the direction of the rack, a flange is also provided on the outside of the cylinder and adapted to the vertical groove 106. The rack cylinder assembly 15 is installed above the power wheel shaft 5. The rack and the teeth of the power wheel shaft 5 are engaged for transmission. The motor worm assembly and / or the rack cylinder assembly 15 engage to drive the power wheel shaft 5 to rotate so that the integrated carrying chassis moves empty. When the load 9 is placed on the chassis frame 1, the load 9 is pressed onto the long groove 102 to further limit the fixed motor worm assembly and the rack cylinder assembly 15 when outputting a large torque, so that they can be reliably engaged for transmission.

[0036] The motor 13 is provided with a pressure oil input and output interface connected to the vertical external hole 121 or the end external hole 122 for pressure supply, and the rack cylinder assembly is provided with a pressure oil input and output interface connected to the vertical external hole 121 or the end external hole 122 for pressure supply.

[0037] like Figure 1 The ends of the power wheel shaft 5 , the first driven wheel shaft 6 , and the second driven wheel shaft 7 are rolled on the two planes of the concave track 10 .

[0038] The motor-worm assembly can also be two symmetrically arranged motors 13 coaxially connected to a worm 14 .

[0039] The working method is:

[0040] like Figure 1 The integrated carrying chassis travels on the concave track 10, the guide wheel 4 is located in the groove of the concave track 10 for guidance, and the ends of the power wheel axle 5, the first driven wheel axle 6, and the second driven wheel axle 7 are rolled on the two planes of the concave track 10.

[0041] like Figure 3 、 Figure 4 The power source 16 is a hydraulic system including a hydraulic integrated connection block. The power source 16 is fixed on the sinking plate 110 through the hydraulic integrated connection block of the input and output interface, and the input and output oil are to hole one 112 and / or hole two 113 and / or hole three 114. The pressure oil input and output interface is connected to the vertical external hole 121 or the end external hole 122 to supply pressure to the motor 13 and / or the rack cylinder assembly 15. The motor drives the worm to rotate, and the meshing drive power wheel axle 5 rotates to make the integrated carrying chassis move. The bidirectional rack piston of the rack cylinder assembly 15 moves back and forth, and the rack meshes and drives the power wheel axle 5 to rotate to make the integrated carrying chassis move.

[0042] Specifically, Figure 4 When driven by a driving device composed of a single motor worm assembly and a single rack cylinder assembly 15, the meshing driving power wheel shaft 5 rotates to enable the integrated carrying chassis to travel a short distance.

[0043] like Figure 10 When a driving device with two or a single motor worm assembly is used, the motor drives the worm to rotate, which engages and drives the power wheel shaft 5 to rotate, allowing the integrated carrying chassis to travel long distances.

[0044] like Figure 11 When a driving device using two or a single rack cylinder assembly 15 is used, the bidirectional rack piston moves back and forth, and the rack meshes and drives the power wheel shaft 5 to rotate, causing the integrated carrying chassis to travel a short distance.

[0045] A key is set on the chassis frame 1 to prevent the load 9 from sliding. The power wheel axle 5, the first driven wheel axle 6, and the second driven wheel axle 7 distribute the pressure of the load 9. The anti-collision head 2 is used to buffer collisions during movement. The photoelectric detection head 3 senses the space margin and position measurement in the direction of travel. The pressure sensor 8 can detect pressure changes during the hydraulic pressure transmission process.
