The rod 5 is engaged, and a plurality of fixed frames 11 are connected to the upper rear side of the mobile frame 1, and the fixed frames 11 are connected to the second motor 10, and the upper left and right sides of the mobile frame 1 are rotatably connected to the winding wheels 12, and the winding wheels 12 are connected to the adjacent output shafts of the second motor 10, and a pull rope 9 is wound between the winding wheels 12, and a transport frame 13 is slidably connected between the lower parts of the first support frame 2, a plurality of pulleys 8 are provided on the upper part of the adjustment frame 3, and a pulley 8 is also provided on the top of the transport frame 13, and the pull rope 9 is passed around the pulley 8, and a revolving door 14 is rotatably connected to the front of the transport frame 13, and a buffer mechanism 15 is provided on the mobile frame 1, and a limiting mechanism 16 is provided on the buffer mechanism 15.
[0022] like Figure 1 and Figure 3 As shown, the buffer mechanism 15 includes a sleeve 151, a buffer frame 152 and a first spring 153. A plurality of sleeves 151 are connected to the mobile frame 1. The buffer frames 152 are slidably connected between the sleeves 151. The first spring 153 is connected between the bottom of each sleeve 151 and the buffer frame 152. The top of the buffer frame 152 is in contact with the bottom of the transport frame 13.
[0023] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a limiting mechanism 16, which includes a fixed block 161, a second support frame 162, a roller 163, a limiting frame 164 and a second spring 165. The fixed block 161 is connected to the bottom of the transport frame 13, the second support frame 162 is connected to the upper rear side of the mobile frame 1, the roller 163 is rotatably connected to the upper part of the second support frame 162, the limiting frame 164 is slidably connected to the rear of the buffer frame 152, and the second spring 165 is connected between the left and right parts of the limiting frame 164 and the rear side of the buffer frame 152, and the limiting frame 164 is squeezed and fitted with the roller 163.
[0024] When the utility model is in use, the elevator is first moved as a whole to the engineering material conveying area through the mobile frame 1, and then the first motor 4 is started according to the transportation height requirement. The output shaft of the first motor 4 rotates to drive the worm 5 to rotate. The rotation of the worm 5 drives the screw rod 7 to rotate through the cooperation with the worm wheel 6. The screw rods 7 on both sides rotate synchronously, and the adjustment frame 3 is controlled to move up and down on the first support frame 2. The first support frame 2 moves up and down to adjust the height that the transport frame 13 can subsequently lift, so that the lifting height of the transport frame 13 is adapted to the height of material transportation. After the material lifting height control is completed, the first motor 4 is turned off, and then the motor is rotated. Open the revolving door 14, put the materials into the transport rack 13, then close the transport rack 13, and start the second motor 10. The output shaft of the second motor 10 rotates to drive the winding wheel 12 to rotate. The winding wheel 12 rotates to reel in the pull rope 9, and cooperates with the pulley 8 to lift the transport rack 13 upward, so that the transport rack 13 drives the materials to move upward. After the materials are lifted to the specified position, the workers unload the materials from the transport rack 13, and then the second motor 10 controls the winding wheel 12 to rotate, releases the pull rope 9, so that the transport rack 13 gradually moves downward, and the transport rack 13 is reset. When the transport rack 13 moves downward, the slow The punch frame 152 cooperates with the first spring 153 to reduce and buffer the kinetic energy of the transport frame 13 when it moves downward. When the transport frame 13 is loaded with too heavy materials and exceeds the transport limit of the transport frame 13, the weight of the transport frame 13 increases and presses the buffer frame 152 downward. The buffer frame 152 moves downward and drives the limiting frame 164 to move downward. The limiting frame 164 moves downward and is restricted by the roller 163 and squeezed into the fixed block 161. When the limiting frame 164 is stuck in the fixed block 161, the locking operation of the transport frame 13 is completed through the fixed block 161, so that the limiting frame 164 and the fixed block 161 are mutually locked. The cooperation of the connection makes the buffer frame 152 and the transport frame 13 connected as a whole, so that the transport frame 13 cannot be lifted upward, thereby preventing the material in the transport frame 13 from being overloaded and reducing the possibility of accidents. When the weight of the material is reduced, the first spring 153 rebounds to control the buffer frame 152 to move upward, and the upward movement of the buffer frame 152 drives the limiting frame 164 to move upward. The limiting frame 164 moves upward and disengages from the roller 163, and the second spring 165 rebounds, so that the limiting frame 164 slides back and disengages from the fixed block 161, thereby achieving the purpose of unlocking the transport frame 13, so that the transport frame 13 can perform normal lifting and lowering movements.
