[0022] Please see Figure 1-4 This utility model provides a steel bar hoisting and clamping device for civil engineering, including a lifting component 100 and a clamping component 200;
[0023] The lifting assembly 100 includes a bracket 101. A first motor 102 is mounted on the upper end of the bracket 101. A first bevel gear 103 is connected to the output end of the first motor 102. A first lead screw 104 is mounted on one side of the lower end of the bracket 101. A second bevel gear 105 is fixedly connected to the upper end of the first lead screw 104. The first bevel gear 103 and the second bevel gear 105 are meshed together. A first guide rod 106 is mounted on the other side of the bracket 101. A lifting plate 107 is connected to the side surfaces of the first lead screw 104 and the first guide rod 106. Two second motors 108 are mounted on one side of the lower end of the lifting plate 107. Two transmission gears 109 are connected to the lower end of the lifting plate 107. One end of the transmission gear 109 and the output of the second motor 108 are both connected to transmission wheels 110. A transmission belt 120 is wound between the two transmission wheels 110.
[0024] The clamping assembly 200 includes two movable plates 201 mounted on the lower end of the lifting plate 107. Each movable plate 201 has several first racks 202 connected to its lower end, and the two movable plates 201 are connected to each other via the first racks 202. Each movable plate 201 has a lifting shaft 203 connected to its lower end. Several second racks 204 are connected to both sides of the lifting shaft 203. A mounting plate 205 is sleeved on the side surface of the lifting shaft 203, and two half-gears 206 are rotatably connected to the lower end of the mounting plate 205. Both half gears 206 are meshed with the second racks 204 on both sides of the lifting shaft 203. The side surfaces of both half gears 206 are fixedly connected with clamps 207.

[0025] In one specific embodiment, the lifting assembly 100, in conjunction with the clamping assembly 200, can not only automatically lift steel bars, thereby improving lifting efficiency, but also clamp steel bars of different lengths, thus enhancing the versatility of the clamping equipment. In use, the first motor 102 is started, driving the first bevel gear 103 clockwise, which, in conjunction with the second bevel gear 105, drives the first lead screw 104. Simultaneously, the first guide rod 106 controls the lifting plate 107 to descend, carrying the mounting plate 205 and the clamping plate 207. Next, the second motor 108 is started, driving the output drive wheel 110 to rotate. In conjunction with the drive belt 120, this drives another drive wheel 110 and the drive gear 109. At this time, the drive gear 109 and the first… The rack and pinion 202 are engaged, thus controlling the two moving plates 201 to move closer or further apart, thereby adjusting the distance between the clamping plates 207 at the lower ends of the two mounting plates 205. Finally, the third motor 220 is started, driving the fourth bevel gear 230 to rotate. The rotation of the third bevel gear 210 drives the second lead screw 208 to rotate. The second guide rod 209 controls the mounting plates 205 and the lugs 221 to move along the upper end of the second lead screw 208, causing the lifting shaft 203 to descend along the limiting hole 231. At this time, the half gear 206 and the second rack and pinion 204 are engaged, thereby controlling the rotation of the half gear 206 to unfold the two clamping plates 207. Finally, controlling the lifting shaft 203 to rise allows the two clamping plates 207 to clamp steel bars of different lengths, thus enhancing the versatility of the clamping equipment.
[0026] Please see Figure 2 and Figure 3The lower end of the bracket 101 is threaded with several self-locking casters 111, and the lower end of the lifting plate 107 is connected to two hanging plates 112. Both transmission gears 109 are rotatably connected between the hanging plates 112.
[0027] In one specific embodiment, the self-locking caster wheel 111 facilitates the movement of the bracket 101 to enable steel bar hoisting operations, and the hanging plate 112 improves the installation stability of the transmission gear 109.
[0028] Please see Figure 2 and Figure 3 The lower end of the lifting plate 107 is fixedly connected to the mounting rod 121, and a crossbar 122 is inserted into the mounting rod 121.
[0029] In one specific embodiment, the mounting rod 121 facilitates the installation stability of the crossbar 122, and the crossbar 122 can be disassembled by pulling it out of the mounting rod 121.
[0030] Please see Figures 2-4 Two movable blocks 211 are fixedly connected to the upper ends of the two movable plates 201. Guide holes 212 are opened on the surface of the two movable blocks 211, and the crossbar 122 is inserted into the inside of the guide holes 212.
[0031] In one specific embodiment, the crossbar 122 is inserted into the guide hole 212. When the moving plate 201 moves, the crossbar 122 helps to improve the stability of the moving plate 201 during movement.
[0032] Please see Figure 4 Both sides of the mounting plate 205 are fixedly connected with ear blocks 221. The surfaces of the two ear blocks 221 are respectively provided with screw holes 222 and through holes 223. The second lead screw 208 is threaded into the inside of the screw hole 222, and the second guide rod 209 is inserted into the inside of the through hole 223.
[0033] In one specific embodiment, the second lead screw 208 is threaded into the screw hole 222. When the second lead screw 208 rotates, it can control the lifting and lowering of the mounting plate 205 and the lug 221, so as to control the clamping plate 207 to perform clamping operation on the reinforcing bar.
[0034] Please see Figure 4 The upper end of the mounting plate 205 has a limit hole 231, and the lifting shaft 203 is inserted into the limit hole 231.
[0035] In one specific embodiment, the limiting hole 231 is used to limit the lifting shaft 203 and improve the stability of the lifting shaft 203 when it is raised or lowered.
[0036] Please see Figure 4 The 207 clamping plate is made of alloy steel.
[0037] In one specific embodiment, the clamping plate 207 made of alloy steel can enhance its wear resistance and strength, extend its service life, and improve the clamping stability of the reinforcing bars.
[0038] Working principle: In use, the first motor 102 is started, driving the first bevel gear 103 to rotate clockwise. This, in conjunction with the second bevel gear 105, drives the first lead screw 104 and the first guide rod 106 to rotate, thereby controlling the lifting plate 107 to descend along with the mounting plate 205 and the clamping plate 207. Then, the second motor 108 is started, driving the output drive wheel 110 to rotate. This, in conjunction with the drive belt 120, drives another drive wheel 110 and the drive gear 109 to rotate. Through the meshing connection between the drive gear 109 and the first rack 202, the two moving plates 201 can be controlled to move closer or further apart, thus enabling the lifting plate 107 to descend along with the mounting plate 205 and the clamping plate 207. The distance between the clamping plates 207 at the lower ends of the two mounting plates 205 is adjusted. Finally, the third motor 220 is started, which drives the fourth bevel gear 230 to rotate, and the third bevel gear 210 rotates, which in turn drives the second lead screw 208 to rotate. Then, in conjunction with the second guide rod 209, the mounting plates 205 and the ear block 221 are controlled to move along the upper end of the second lead screw 208. Therefore, the lifting shaft 203 can be controlled to descend along the limiting hole 231, thereby controlling the half gear 206 to rotate and causing the two clamping plates 207 to unfold. Finally, the lifting shaft 203 is controlled to rise, which can control the two clamping plates 207 to clamp steel bars of different lengths, so as to enhance the versatility of the clamping equipment.
