[0038] like Figure 1 , Figure 8 and Fig. 9 As shown, the limit block 806 includes a wedge block I807 and a wedge block II808, and the wedge block I807 and the wedge block II808 are both penetrated and slidably installed on the upper part of the guide frame 802, and the wedge block I807 and the wedge block II808 are wedge blocks symmetrical on the upper inclined surface, wherein the wedge block I807 is located on the inner side, and the wedge block I807 is located on the outer side, and the wedge block I807 and the wedge block II808 are symmetrically combined into a limit block 806, and the bottom of the wedge block I807 and the wedge block II808 are both installed with a separate return spring, and the top inclined surfaces of the wedge block I807 and the wedge block II808 are flush with the slider I803.

[0039] like Figure 6, Figure 7 and Fig.10 As shown, the guide frame 802 is provided with a locking assembly 9, and the locking assembly 9 includes a guide block 901, a mounting frame 902, a slider II 903 and a limit rod 904. The two ends of the guide frame 802 are provided with guide blocks 901. The guide frame 802 is slidably installed with the mounting frame 902 through the guide blocks 901 on both sides. A compression spring is provided between the guide block 901 and the mounting frame 902.

[0040] When the lift is used for construction, the construction workers stop the lift base 1 at the construction site, and drive the support pillar 703 to support the ground by controlling the supporting hydraulic cylinder 702, and fine-tune the supporting length of the support pillar 703 according to the different concave and convex conditions of the ground, so that the lift base 1 can be stably placed on the construction ground, and after the baffle 501 is rotated and opened from the material placing frame 5, the construction raw materials are placed in the material placing frame 5, and the construction workers then climb onto the adjustment plate 4 by rotating and opening the movable guardrail 402, and after closing the movable guardrail 402, the lift base 1 is enabled, and the lift base 1 synchronously lifts the construction workers on the adjustment plate 4 and the construction raw materials in the material placing frame 5 upward, and when the construction position needs to be adjusted, the electric screw on the guide plate 3 can be used to drive the adjustment plate 4 to move upward. When the adjusting plate 4 is translated forward and out of the guide plate 3, the support plate I601, driven by the adjusting plate 4, overcomes the elastic force of the elastic member I603 and synchronously extends forward the top frame 2 and stably supports the bottom of the adjusting plate 4. When the adjusting plate 4 is translated backward and out of the guide plate 3, the support plate II602 will similarly overcome the elastic force of the elastic member II604 and synchronously extend backward the top frame 2 and stably support the bottom of the adjusting plate 4. In the process of continuous lifting of the lifting base 1, the rising connecting frame 805 will respectively pull the sliders I803 on both sides to move inward through the support rods 804. Initially, under the action of the compression spring, the limit rod 904 in the mounting frame 902 is locked in the bayonet of the wedge block I807 and the wedge block II808. 806, and the limit block 806 is separated into a wedge block Ⅰ 807 and a wedge block Ⅱ 808. 08. During the falling process, since the upwardly propped support rod 804 is supported on the bottom of the guide plate 3, the falling guide plate 3 will push the support rods 804 on both sides downward. When the two support rods 804 are stretched outward, the sliders Ⅰ803 on both sides slide outward on the guide frame 802. The outward sliding slider Ⅰ803 first contacts the inclined surface of the adjacent wedge block Ⅰ807. At this time, the slider Ⅰ803 can directly overcome the elastic force of the return spring and press down the adjacent wedge block Ⅰ807. When the slider Ⅰ803 continues to slide and contacts the adjacent wedge block Ⅱ808, the slider Ⅰ803 will contact the vertical surface of the wedge block Ⅱ808. At this time, the wedge block Ⅱ808 will block and limit the slider Ⅰ803 from continuing to slide outward, so that the support rod 804 cannot continue to be stretched outward.In this way, the support rod 804 is fixedly supported at the bottom of the guide plate 3, so that the falling guide plate 3 and the adjustment plate 4 are stopped immediately, thereby ensuring the safety of the construction workers on the adjustment plate 4.

[0041] Embodiment 2: Based on embodiment 1, Figure 1 , Fig.11 and Fig.12 As shown, it also includes a trigger assembly 10, which includes a guide rod 101, a linkage rod 102, a wedge strip 103 and an extrusion rod 104. The two ends of the support rod 804 are fixedly connected to the guide rod 101, and the linkage rod 102 is slidably arranged on the adjacent guide rod 101. The linkage rod 102 is close to the support rod 804, and the lower end of the linkage rod 102 is connected to the installation frame 902. The wedge strip 103 is slidably connected inside the connection frame 805. It is composed of a strip and a wedge block, the wedge block of the wedge strip 103 extends upward to the edge of the adjustment plate 4, and the bottom of the wedge strip 103 is fixedly connected with an extrusion rod 104, and the extrusion rod 104 is a hard rod with a protrusion in the middle, and the extrusion rod 104 is located between the linkage rod 102 and the support rod 804. The extrusion rod 104 presses the linkage rod 102 downward to move, so that the linkage rod 102 drives the limit rod 904 on the installation frame 902 to release the lock of the wedge block I807 and the wedge block.

[0042] like Figure 1 and Fig.13 As shown, the adjustment plate 4 is provided with an emergency component 11, and the emergency component 11 includes a lower pressure plate 111 and a pedal 112. The lower pressure plate 111 is symmetrically and slidably installed on the front and rear sides of the adjustment plate 4. The lower pressure plate 111 is in contact with the top surface of the wedge block strip 103. A spring is arranged between the lower pressure plate 111 and the fixed guardrail 401. The pedal 112 is fixedly connected to the lower pressure plate 111. By stepping on the pedal 112, the lower pressure plate 111 presses down the wedge block strip 103, so that the linkage rod 102 can push out the installation frame 902 in an emergency.

[0043] When the adjusting plate 4 is translated out of the guide plate 3, the adjusting plate 4 will press on the wedge strip 103 on the same side. The compressed wedge strip 103, under the guidance of the connecting frame 805, drives the extrusion rod 104 to press downward on the linkage rod 102. The extruded linkage rod 102 will slide under the guidance of the guide rod 101. The sliding linkage rod 102 will synchronously drive the installation frame 902 to move, so that the installation frame 902 automatically detaches from the guide frame 802 when the adjusting plate 4 is translated out of the guide plate 3, so that the limit rod 904 of the installation frame 902 no longer locks the limit block 806, thereby the wedge block II 80 8 can automatically block and lock the slider I803 to avoid the safety hazard of falling of the adjusting plate 4 that is translated out of the guide plate 3 in the event of a failure. The construction personnel can also manually step on the pedal 112 on the adjusting plate 4. The stepped pedal 112 will drive the lower pressure plate 111 to move downward to overcome the elastic force of the spring, so that the lower pressure plate 111 directly presses down the wedge block strip 103, so that the separation of the guide frame 802 and the installation frame 902 can be manually controlled in an emergency, thereby realizing the emergency limit slider I803 of the wedge block II808, so that the elevator can be stopped urgently in the event of a sudden fall to avoid major safety accidents.

[0044] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention.
