[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example
[0026] Reference Figure 1-3, a water supply and drainage construction hoisting device includes a main arm 100 and a jib 101 adjustably connected to both ends thereof, a mounting plate 102 is provided at the end of the jib 101, a clamping and fixing assembly 200 is provided at the bottom of the mounting plate 102, a support frame 103 is provided at the top of the main arm 100, a first cable 105 is provided at the top of the support frame 103 through a connecting ear 104, a driving assembly 300 is provided at the top of the main arm 100 for adjusting the support frame 103 to change the position of the first cable 105 to change the center of gravity of the hoisting device to maintain a stable and balanced state, a cable assembly 400 is provided between the two jibs 101 and the support frame 103 to improve the stability of the hoisting device, when in use, the relative position between the main arm 100 and the jib 101 is adjusted, and the position of the clamping and fixing assembly 200 is adjusted so that it can adjust the lengths of the hoisting device. The water supply and drainage pipe is clamped and fixed, and then the water supply and drainage pipe to be hoisted is fixed by the clamping and fixing component 200, and then the first cable 105 is connected to the lifting equipment for lifting operation. Since it is difficult to accurately fix the middle position of the water supply and drainage pipe during fixing, the center of gravity will not be at the center of gravity during lifting, and a tilted state will occur during lifting. At this time, the position of the first cable 105 is adjusted by the driving component 300 to change the lifting force point so that the center of gravity of the lifting device is in the center position. At this time, the balance of the lifting device can be maintained, and its lifting is more stable. By setting the cable component 400, part of the load can be dispersed to the support frame 103, and at the same time, it can have a tensioning effect between the main arm 100 and the auxiliary arm 101, further improving the stability of the lifting device.
[0027] Reference Figure 1-3 The driving assembly 300 includes a mounting base 301 arranged on the top of the main arm 100, a transmission screw 302 arranged on the inner side of the mounting base 301, and a driving motor 303 arranged on the outer side wall of the mounting base 301, wherein the output end of the driving motor 303 passes through the mounting base 301 and is connected to the transmission screw 302.
[0028] A slide groove 108 is provided on the top of the main arm 100, and the support frame 103 is slidably connected in the slide groove 108; when in use, when the lifting device is in a tilted state, the drive motor 303 is started to drive the transmission screw 302 connected to its output end to rotate, and the slide groove 108 provided makes the support frame 103 only able to slide along the slide groove 108. Therefore, when the transmission screw 302 rotates, it will drive the support frame 103 to move along the slide groove 108, thereby adjusting the position of the support frame 103 and the first cable 105, and then the center of gravity of the lifting device can be adjusted to make it in a balanced state, thereby avoiding the situation where the water pipe falls due to being in a tilted state during lifting.
[0029] Reference Figure 1-3A positioning hole 106 is provided on both the main arm 100 and the auxiliary arm 101, and a locking bolt 107 is provided inside the positioning hole 106. Through the provided positioning hole 106 and the locking bolt 107, it is convenient to fix the adjusted main arm 100 and the auxiliary arm 101, thereby completing the adjustment of the position of the clamping and fixing assembly 200.
[0030] The cable assembly 400 includes a connecting ring 401 arranged on the top of the two mounting plates 102, a pulley component 402 arranged on the top of the support frame 103, and a second cable 403 connected to the connecting ring 401 at both ends and abutting against the pulley component 402. Through the arrangement of the cable assembly 400, the two auxiliary arms 101 and the main arm 100 can be tightened, and at the same time, part of the load can be dispersed to the support frame 103, further improving the stability of the lifting device.
[0031] In order to ensure the feasibility of the cable assembly 400 and the main arm 100 and the auxiliary arm 101 during use, the support frame 103 is a retractable structure.
[0032] Reference Figure 1-5 The clamping and fixing assembly 200 includes a scissor-type link component 202 connected to the bottom of the mounting plate 102 through a connecting seat 201 and a fixed clamp 203 connected to the end of the scissor-type link component 202, wherein a limiting component 204 is also provided between the scissor-type link component 202 and the connecting seat 201.
[0033] The limiting component 204 includes a hook 205 rotatably set on the outer wall of the connecting seat 201 and a positioning column 206 set on the outer wall of the scissor-type link component 202 and matched with the hook 205. The fixed clamping component adopts a scissor-type connection structure, which can not only realize the clamping and fixation of the water supply and drainage pipe, but also, under the action of the gravity of the water supply and drainage pipe, the scissor-type link component will be hinged and rotated, thereby driving the two fixed claws 203 to be fixed close to each other, improving the clamping force of the water supply and drainage pipe, and then improving the fixing effect of the water supply and drainage pipe and the safety during lifting. In conjunction with the limiting component 204, the scissor-type link component 202 can be limited to facilitate the clamping and fixation of the water supply and drainage pipe.
[0034] Specifically, when the water supply and drainage construction hoisting device is in use: the position between the main arm 100 and the auxiliary arm 101 is adjusted according to the length of the water supply and drainage pipe, so that the water pipe can be clamped and fixed more stably. When adjusting, the auxiliary arm 101 is pulled to change its relative position relative to the main arm 100, and then the adjusted main arm 100 and auxiliary arm 101 are fixed through the provided positioning holes 106 and locking bolts 107, completing the adjustment of the position of the clamping and fixing assembly 200, and clamping the water supply and drainage pipe. When the scissor-type link component 202 is in a fully open state, the fixed jaws 203 are separated and ready to clamp the workpiece. At this time, the hook 205 is in a non-limiting position and does not hinder the movement of the scissor-type link component 202. The fixed jaws 203 are placed on both sides of the water pipe to be hoisted and placed closely together. The main arm 100 and the auxiliary arm 101 are driven upward by the lifting equipment and the first cable 105. Under the action of the gravity of the clamping and fixing component 200 itself, the two fixed jaws 203 approach each other and clamp the water pipe. At the same time, by adopting the scissor-type connecting component 202, due to the action of the water supply and drainage pipe's own gravity during hoisting, the two fixed clamping claws 203 will be close to each other to make the clamping more firmly, further improving the fixing effect of the water supply and drainage pipe. After hoisting to the designated position, the main arm 100 and the auxiliary arm 101 are placed below. Under the action of the main arm 100 and the auxiliary arm 101, the scissor-type connecting rod components 202 are rotated and folded, and the fixed clamping claws 203 open the water pipe to release the clamping state, and at the same time, the hook 205 is hung on the positioning column 206. At this time, the scissor-type link component 202 is limited and will not rotate to clamp and fix the water pipe. It can be removed by lifting equipment. When the water pipe needs to be clamped and fixed again, the hook 205 is removed from the positioning column 206 to release the limit and clamp and fix the next water pipe again. Secondly, the cable assembly 400 provided in conjunction can have a tensioning effect between the two auxiliary arms 101 and the main arm 100, and at the same time can disperse part of the load to the support frame 103, further improving the stability of the lifting device.
[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
