[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 4 A scissor-type lift with good safety is shown, including a scissor-type lifting mechanism, which includes a base 1. Scissor-type lifting frames 4 are correspondingly arranged on the front and rear sides of the top of the base 1. The bottom end of the scissor-type lifting frame 4 is hinged on the base 1. The scissor-type lifting frame 4 is of the existing common scissor-type and will not be described in detail. Two mounting blocks are provided on the top of the scissor-type lifting frame 4, which are fixed to the outside of the scissor-type lifting frame 4. The two mounting blocks are respectively fixedly connected to the left and right sides of the bottom of the side support mechanism, and are specifically fixed in a coaxial rod manner, that is, the side support mechanism, the mounting block and the scissor-type lifting frame 4 are fixed together with the same threaded shaft and nut.

[0024] A baffle platform is arranged between the two side support mechanisms, and the baffle platform includes a fixed platform 3, a first side baffle 9 and a second side baffle 10. The fixed platform 3 is fixedly connected between the two side support mechanisms, and the first side baffle 9 and the second side baffle 10 are respectively arranged on the left and right sides of the fixed platform 3.

[0025] The first side baffle 9 and the second side baffle 10 on both sides of the fixed platform 3 can be rotated 90 degrees at the fixed platform 3, so that the first side baffle 9 and the second side baffle 10 can maintain a vertical state with the fixed platform 3. When adjusting the angle of the first side baffle 9 and the second side baffle 10, it should be noted that it also includes two fixed beams and two jacking mechanisms. The fixed beam is fixedly connected to one side of the bottom of the front and rear side support mechanisms, and the jacking mechanism is fixedly connected to the fixed beam; the fixed beam includes two mounting plates 5, and the front and rear mounting plates 5 are movably connected with a fixed rod 6 through a bearing sleeve 61. The jacking mechanism includes a lifting mechanism 7, and the lifting mechanism 7 is fixedly connected to the fixed rod 6. The free end of the lifting mechanism 7 is hinged to the bottom of the baffle platform. When the free end of the lifting mechanism 7 is raised, the free ends of the two lifting mechanisms 7 are hinged to the first side baffle 9 and the second side baffle 10 respectively, so that the first side baffle 9 and the second side baffle 10 can be rotated, and the lifting mechanism 7 is set on the fixed rod 6. When jacking, the fixed rod 6 can drive the lifting mechanism 7 to rotate, and the free end of the jacking mechanism is hinged to the bottom of the baffle platform.

[0026] The purpose of this setting is that during use, the baffle platform can be set to an expanded state according to the needs of use, so as to increase the placement area and the number of ways. When the first side baffle 9 and the second side baffle 10 are rotated to a ninety-degree state, they can play a protective role when lifting materials, such as columnar objects such as pipes, so as to improve the stability and safety of material lifting and transportation, and can also be adjusted according to different materials, so as to improve the safety and stability of the device.

[0027] It should be noted that, in the above embodiment, the front and rear sides of the first side baffle 9 and the second side baffle 10 are both provided with slide grooves 13, and two side support mechanisms are provided in the length direction of the top of the scissors-type lifting mechanism. The side support mechanism includes a fixed slide rail 11 and a movable slide rail 12. The top of the fixed slide rail 11 is hinged with a support bar 111, and the top of the support bar 111 is slidably connected to the bottom of the movable slide rail 12. The support bar 111 is movably connected with a sliding bar 121 through a limiting rod 122. The top of the sliding bar 121 is hinged to the bottom of the movable slide rail 12, and the bottom end of the sliding bar 121 is slidably connected to the top of the fixed slide rail 11.

[0028] When the first side baffles 9 and the second side baffles 10 on both sides are lifted by the lifting mechanism 7, the slide grooves 13 on the first side baffles 9 and the second side baffles 10 can guide the fixed slide bar 14, so that the fixed slide bar 14 can lift the movable slide rail 12 after guidance, and then the fixed slide rail 11 and the movable slide rail 12 can be separated from each other, so that the distance between the fixed slide rail 11 and the movable slide rail 12 is increased. At this time, the support bar 111 and the sliding bar 121 can rotate to form a supporting state, thereby ensuring the stability between the fixed slide rail 11 and the movable slide rail 12 in the height direction.

[0029] Of course, it also includes a lifting cylinder 2, which is a power mechanism that enables the scissor-type lifting mechanism to rise and fall. The lifting cylinder 2 is fixedly connected to the top of the scissor-type lifting mechanism, and the free end of the lifting cylinder 2 is fixedly connected to the baffle platform.

[0030] It should be understood that it also includes a fixed slide bar 14, which includes a nut 141. The slide bar 142 on the nut 141 movably passes through the transverse groove on the slide rail 12, and one end of the slide bar 142 passes through the slide groove 13. One end of the slide bar 142 is fixedly connected to the limit block 143. When the fixed slide bar 14 rotates between the first side baffle 9 and the second side baffle 10, the limit block 143 on the slide bar 142 is at the slide groove 13, which can limit the fixed rod 14, and the slide bar 142 can move synchronously in the transverse groove and the slide groove 13, and then the slide groove 13 can lift the slide bar 142, thereby ensuring that the fixed slide rail 11 and the movable slide rail 12 are separated, so that a side enclosure can be formed, so that the baffle platform can form an enclosure, so that people can stand.

[0031] It also includes a protection rod 15, and there are multiple protection rods 15. The multiple protection rods 15 are arranged between the rotation points of the two scissor lift frames 4 to ensure that the scissor lift frames 4 on the front and rear sides remain stable and fixed.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
