When the door opening motor 118 is started, the corresponding double-threaded door opening screw rod 117 is driven to rotate. Under the action of the transmission belt 119, the two double-threaded door opening screw rods 117 rotate synchronously, that is, the two car doors 104 move away from or towards each other.

[0036] A support slide 114 is slidably installed on the inner side of the inner car 109, and a displacement screw 120 is rotatably installed on the inner car 109.

When the two car doors 104 are at the farthest position, the displacement motor 121 is started to drive the displacement screw 120 to rotate, so that the support slide 114 moves in the direction away from the displacement motor 121, that is, the support slide 114 moves from the area between the two car doors 104 to the outside of the inner car 109.

[0037] A multi-arm skateboard 111 and two multi-arm skateboards 110 are also slidably installed on the inner side of the inner car 109. The multi-arm skateboard 110 and the multi-arm skateboard 111 are both located above the upper surface of the support skateboard 114. The two multi-arm skateboards 111 are symmetrically slidably installed inside the inner car 109. The two multi-arm skateboards 110 are arranged on both sides of the multi-arm skateboard 111.

At this time, the multi-arm slide 110 and the multi-arm slide 111 are located at the closest position to the corresponding double-headed threaded unfolding screw rod 122. At this time, the two unfolding slides 124 of the same unfolding unit 1 are located at the farthest position apart, and the two unfolding slides 125 of the same unfolding unit 1 are located at the farthest position apart.

[0039] The double-threaded unfolding screw rod 122 is driven to rotate, so that the corresponding two unfolding slides 124 move toward each other, and then the two ends of the corresponding X-shaped folding frame 123 connected to the two unfolding slides 124 move toward each other, and then the corresponding two unfolding slides 125 move toward each other, and then the multi-arm slide plate 110 or the multi-arm slide plate 111 corresponding to the X-shaped folding frame 123 moves in the direction away from the corresponding double-threaded unfolding screw rod 122, and at this time the multi-arm slide plate 110 or the multi-arm slide plate 111 slides relative to the inner car 109.

The limiting strips 133 are symmetrically fixedly arranged on the multi-arm slide 112, and the limiting strips 133 are provided with arc-shaped sliding grooves that cooperate with the fan-shaped limiting strips 132. The fan-shaped limiting strips 132 and the limiting strips 133 are used to limit the positions of the two multi-arm slides 112.

[0042] In the initial position, the two car doors 104 are located at the closest position to each other. At this time, the two multi-arm slides 112 are located at the closest position to each other. The positioning block 128 is in engagement with the corresponding sliding groove on the multi-arm slide 112. At this time, the two corresponding limiting strips 133 on the two multi-arm slides 112 are in contact, that is, the two limiting strips 133 closest to the fan-shaped limiting strips 132 are in contact, and the fan-shaped limiting strips 132 and the arc-shaped sliding grooves on the two limiting strips 133 closest to the fan-shaped limiting strips 132 are in engagement. Under the action of the fan-shaped limiting strips 132, the two limiting strips 133 cannot move relative to each other, that is, the two multi-arm slides 112 cannot move relative to each other.

The unfolding unit 2 includes an X-shaped folding frame plate 123, a double-headed threaded unfolding screw rod 2 126, and two unfolding slides 1 124. The double-headed threaded unfolding screw rod 2 126 is rotatably installed on the corresponding car door 104. There is friction between the car door 104 and the double-headed threaded unfolding screw rod 2 126. The two unfolding slides 1 124 are slidably installed on the car door 104 on which the double-headed threaded unfolding screw rod 2 126 is rotatably installed. A transmission shaft 146 is rotatably installed on the unfolding slide 124, and a torsion spring is arranged between the transmission shaft 146 and the corresponding unfolding slide 124, one end of the torsion spring is fixedly connected to the transmission shaft 146, and the other end of the torsion spring is fixedly connected to the corresponding unfolding slide 124, a double-headed threaded unfolding screw rod 126 on the car door 104 and the two transmission shafts 146 form a spiral pair, two unfolding slides 125 are slidably installed on the auxiliary slide 113, and the four ends of the X-shaped folding frame plate 123 in the same unfolding unit 2 are respectively connected to the two unfolding slides 124 and the two unfolding slides 125.

[0044] A transmission pulley 130 is symmetrically installed on the double-headed threaded expansion screw rod 126 for rotation, and a torsion spring is arranged between the transmission pulley 130 and the double-headed threaded expansion screw rod 126. One end of the torsion spring is fixedly connected to the double-headed threaded expansion screw rod 126, and the other end of the torsion spring is fixedly connected to the corresponding transmission pulley 130. A driven pulley 131 is also fixedly installed on the limiting circular plate 129, and a limiting belt 147 is arranged between the driven pulley 131 and the corresponding transmission pulley 130. A limiting block 135 is symmetrically fixedly arranged on the auxiliary slide 113, and a limiting short column 134 is also fixedly arranged on the limiting circular plate 129. The limiting short column 134 and the limiting block 135 are used to limit the rotation position of the limiting circular plate 129.

[0045] Auxiliary separation plates 115 are symmetrically fixed at both ends of the car door 104, and auxiliary separation blocks 116 are symmetrically fixed on the multi-arm slide plate 112. The distance between the two auxiliary separation plates 115 located at the same end of the car door 104 is equal to the length of the auxiliary separation block 116. When the auxiliary separation block 116 is engaged with the corresponding two auxiliary separation plates 115, friction exists between the three.

[0046] In the initial position, the two multi-arm slide plates 112 are at the closest position to each other, the fan-shaped limit strips 132 are in engagement with the corresponding two limit strips 133, the torsion spring between the expansion slide seat 124 on the car door 104 and the transmission shaft 146 is not compressed, the torsion spring between the transmission pulley 130 and the double-headed threaded expansion screw rod 126 is not compressed, the two multi-arm slide plates 112 are at the farthest position from the multi-arm slide plate 111, the multi-arm slide plate 112 is not in contact with the inner car 109, and the multi-arm slide plates 112 are not in contact with each other. The surface of the third 112 closest to the multi-arm skateboard 111 is on the same plane as the end surface of the inner car 109 farthest from the multi-arm skateboard 111. The two auxiliary separation blocks 116 on the multi-arm skateboard 112 are respectively located between the corresponding two auxiliary separation plates 115. At this time, the end surface of the auxiliary separation plate 115 closest to the multi-arm skateboard 111 and the surface of the multi-arm skateboard 112 closest to the multi-arm skateboard 111 are on the same plane, and the limiting short column 134 is in contact with the corresponding limiting block 135.

[0047] Drive the double-threaded unfolding screw rod 2 126 to rotate. At this time, the multi-arm slide plate 3 112 is located at the farthest position from the multi-arm slide plate 2 111, that is, the two unfolding slide seats 124 on the car door 104 are located at the farthest position, so the unfolding slide seat 124 will not continue to move relative to the double-threaded unfolding screw rod 2 126. The torsion spring between the unfolding slide seat 124 and the transmission shaft 146 is compressed, and the transmission pulley 130 and the double-threaded unfolding screw rod 2 126 rotate synchronously. Under the action of the driven pulley 131 and the limiting belt 147, the two limiting circular plates 129 rotate synchronously, and the fan-shaped limiting strip 146 rotates synchronously. The plate 132 rotates synchronously, and the limiting short column 134 rotates in the direction away from the limiting block 135, eventually causing the fan-shaped limiting strip 132 to disengage from the corresponding two limiting strips 133, that is, the fan-shaped limiting strip 132 releases the lock on the positions of the two multi-arm slide plates 112. At this time, the door opening motor 118 is started to make the two car doors 104 move away from each other. Under the action of the auxiliary separation plate 115 and the auxiliary separation block 116, the two multi-arm slide plates 112 move away from each other, and the multi-arm slide plate 112 contacts the inner car 109 and slides relative to the inner car 109.

[0048] When the two multi-arm slides 3 112 are in an engaged state and the fan-shaped limiting strips 132 are in an engaged state with the corresponding two limiting strips 133, the double-headed threaded unfolding screw rod 2 126 is driven to rotate, and under the action of the torsion spring between the unfolding slide 124 and the transmission shaft 146, the two unfolding slides 124 on the car door 104 move in a direction approaching each other. At this time, the limiting short column 134 contacts the limiting block 135 and cannot continue to rotate, that is, the transmission pulley 130 cannot continue to rotate, and the torsion spring between the transmission pulley 130 and the double-headed threaded unfolding screw rod 2 126 is compressed. Then, under the action of the X-shaped folding frame plate 123, the two unfolding slides 2 125 on the auxiliary slide 113 move in a direction approaching each other, that is, the two multi-arm slides 3 112 move in a direction close to the multi-arm slide 2 111.

The outer car 102 is connected to the traction machine through multiple steel wire ropes 103, and the outer car 102 is moved in the elevator shaft 101 through the steel wire ropes 103 and the traction machine. When it is necessary to transport goods, the brake motor 106 is started to drive the double-headed threaded brake screw 108 to rotate, so that the two brake slides 105 move in a direction close to each other, that is, the brake friction blocks 107 are all in contact with the slide rail of the elevator shaft 101. Under the action of the friction force between the brake friction blocks 107 and the slide rail of the elevator shaft 101, the position of the outer car 102 is fixed. When the outer car 102 falls freely in an emergency, the brake friction blocks 107 can also be made to contact the slide rail of the outer car 102 to brake the free fall of the outer car 102.

[0053] In the initial position, the two multi-arm slide plates 110 are located at the farthest positions, and the multi-arm slide plate 2 111 and the multi-arm slide plate 3 112 are located at the farthest positions. After the brake friction block 107 completes the fixation of the external car 102, the drive motor 145 is started to drive the drive circular plate 141 to rotate. Under the action of the transmission short column 143 and the fan-shaped slide groove 144, the fan-shaped slide groove 144 moves relative to the transmission short column 143, that is, the drive circular plate 141 rotates relative to the drive circular plate 2 142. Under the action of the drive belt 2 137, the unfolding pulley 2 138 and the drive circular plate 139 rotate synchronously, and the straight-line rotating plate Under the action of 140, the double-headed threaded unfolding screw rod 126 rotates synchronously, the torsion spring between the X-shaped folding frame plate 123 and the transmission shaft 146 is compressed, and under the action of the transmission pulley 130, the driven pulley 131, and the limiting belt 147, the fan-shaped limiting strip 132 disengages from the contact with the corresponding two limiting strips 133, that is, the contact locks the position of the two multi-arm slide plates 112. At this time, the double-headed threaded unfolding screw rod 126, the unfolding pulley 138, the transmission circular plate 139, and the straight-line rotating plate 140 are all rotated 180 degrees, that is, at this time, the two sides of the straight-line rotating plate 140 are parallel to the axis of the double-headed threaded door opening screw rod 117.

[0054] Then the door opening motor 118 is started, and under the action of the double-threaded door opening screw rod 117 and the transmission belt 119, the two car doors 104 are moved to the farthest position. Under the action of the auxiliary separation plate 115 and the auxiliary separation block 116, the two multi-arm slide plates 112 are moved to the farthest position, 149 is disengaged from the transmission circular plate 139, and under the action of the friction between the double-threaded expansion screw rod 126 and the car door 104, the double-threaded expansion screw rod 126 cannot move freely, that is, the torsion spring between the expansion slide seat 124 and the transmission shaft 146 cannot be restored, and then the displacement motor 12 is started. The supporting slide plate 114 is driven to move in a direction away from the displacement motor 121, so that the supporting slide plate 114 moves to the outside of the inner car 109. After placing the goods to be transported on the supporting slide plate 114, the displacement motor 121 is started to return the supporting slide plate 114 to the initial position, that is, the supporting slide plate 114 moves to the position closest to the displacement motor 121, and then the door opening motor 118 is started to return the two car doors 104 to the position closest to each other. At this time, the two multi-arm slide plates 112 are in a connected state, and the positioning block 128 is in a connected state with the corresponding slide groove on the multi-arm slide plate 112.

[0055] Then, the driving motor 145 is started to drive the driving circular plate 141 to rotate. Under the action of the transmission short column 143 and the fan-shaped slide groove 144, the driving circular plate 141 first rotates relative to the driving circular plate 2 142, and enters under the action of the driving belt 2 137, the unfolding pulley 2 138, the transmission circular plate 139, and the straight-line rotating plate 140, the double-headed thread unfolding screw rod 2 126 rotates, and the torsion spring between the double-headed thread unfolding screw rod 2 126 and the transmission shaft 146 begins to recover, and finally the torsion spring between the double-headed thread unfolding screw rod 2 126 and the transmission shaft 146 is completely recovered. At this time, the fan-shaped limiting strips 132 and the corresponding two The limiting strip 133 is in an engaged state, that is, the positions of the two multi-arm slide plates 112 are locked, and at this time, the other end of the fan-shaped slide groove 144 contacts the transmission short column 143, driving the circular plate 141 to continue to rotate, driving the circular plate 141, driving the circular plate 141, driving the second circular plate 142, and the transmission short column 143 to rotate synchronously, and then under the action of the driving belt 136 and the driving belt 2 137, the unfolding pulley 127, the unfolding pulley 2 138, and the transmission circular plate 139 rotate synchronously, that is, the double-headed threaded unfolding screw rod 2 126 and the three double-headed threaded unfolding screw rods 122 rotate synchronously, that is, the two multi-arm slide plates 112 are rotated. The support plate 110 moves in a direction approaching each other, and the multi-arm slide plate 111 and the multi-arm slide plate 112 move in a direction approaching each other, that is, the multi-arm slide plate 110, the multi-arm slide plate 111, and the multi-arm slide plate 112 move to a position close to the center of the supporting slide plate 114. When the multi-arm slide plate 110 contacts the side of the cargo, it cannot move further, and the unfolding pulley 127 continues to rotate. The torsion spring between the unfolding pulley 127 and the double-headed threaded unfolding screw rod 122 corresponding to the multi-arm slide plate 110 is compressed. When the multi-arm slide plate 111 contacts the side of the cargo, it cannot move further. The unfolding pulley 127 continues to rotate, and the torsion spring between the unfolding pulley 127 and the double-headed threaded unfolding screw rod 122 corresponding to the multi-arm slide plate 110 is compressed. 127 continues to rotate, and the torsion spring between the unfolding pulley 127 and the double-headed threaded unfolding screw 122 corresponding to the multi-arm skateboard 2 111 is compressed. When the multi-arm skateboard 3 112 contacts the side of the cargo, it cannot move further, and the double-headed threaded unfolding screw 2 126 continues to rotate, and the torsion spring between the transmission shaft 146 and the unfolding slide 124 corresponding to the multi-arm skateboard 3 112 is compressed, and finally the multi-arm skateboard 1 10, the multi-arm skateboard 2 111, and the multi-arm skateboard 3 112 all contact the side of the cargo on the supporting skateboard 114, thereby achieving the fixation of the cargo, thereby preventing the cargo from being damaged during transportation.

[0056] After the goods are transported to the designated floor, the above steps are performed in reverse. First, the multi-arm skateboard 1 10, the multi-arm skateboard 2 111, and the multi-arm skateboard 3 112 are moved to the positions farthest from the center of the support skateboard 114. Then, the fan-shaped limiting strip 132 contacts the lock of the positions of the two multi-arm skateboards 3 112. Then, the two car doors 104 are moved to the farthest positions. Then, the displacement motor 121 is started to move the support skateboard 114 to the outside of the inner car 109, so that the goods are moved to the outside of the inner car 109.

[0057] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
