[0026] like Figure 3 , 4As shown in Figure 6, the first transmission component includes a vertically arranged mounting groove 22 arranged in a supporting column on one side of the gantry 1, a vertically arranged first screw rod 23 is rotatably mounted in the mounting groove 22, a first bevel gear 24 is fixed to the upper end of the first screw rod 23, and a third bevel gear 28 is fixed to the lower end, a second bevel gear 25 meshing with the first bevel gear 24 is fixed to the first screw rod 10, a horizontally arranged through hole 26 connected to the mounting groove 22 is provided on the supporting column of the gantry 1, a rotating shaft 27 is rotatably mounted in the through hole 26, one end of the rotating shaft 27 extends out of the through hole 26 and a first rotating handle 11 is fixed thereon, and a fourth bevel gear 29 meshing with the third bevel gear 28 is fixed to the other end of the rotating shaft 27; the first rotating handle 11 is arranged at a position convenient for the operator to operate, and of course the first rotating handle 11 here can also be replaced by other power devices, such as a motor.
[0027] When clamping the hoisted electromechanical equipment, the first rotating handle 11 is turned to drive the rotating shaft 27 to rotate, and the fourth bevel gear 29 fixed on the rotating shaft 27 drives the meshing third bevel gear 28 to rotate, so that the vertical first screw 23 in the mounting groove 22 rotates, and driven by the first bevel gear 24 fixed to the upper end of the first screw 23, the second bevel gear 25 will drive the first screw to rotate, so that the two clamping arms 13 are close to each other by the threaded connection between the threaded section and the first slider 12, so as to clamp the electromechanical equipment.
[0028] like Figure 4 As shown, the telescopic arm includes an outer sleeve 14 and a sliding rod 141 slidably inserted in the outer sleeve 14, the outer sleeve 14 is vertically fixed at the bottom of the clamping arm 13, the sliding rod 141 is fixed to the top of the vertical side of the L-shaped clamping plate 15, the L-shaped clamping plate 15 is slidably installed in the outer sleeve 14 through the sliding rod 141, the L-shaped clamping plate 15 is connected to the gantry 1 through a lifting drive component, the lifting drive component includes a vertically arranged slide groove 16 arranged on the opposite side of the support columns on both sides of the gantry 1 and matching the position of the L-shaped clamping plate 15, a vertically arranged second screw rod 17 is rotatably installed in the slide groove 16, a second slider 18 is slidably assembled in the slide groove 16, the second slider 18 is threadedly connected to the second screw 17, the second slider 18 is fixedly connected to the L-shaped clamping plate 15 through a horizontally arranged multi-stage telescopic rod 20, and the second screw 17 is driven to rotate by the second transmission component to realize the up and down movement of the L-shaped clamping plate 15.
[0029] like Figure 4As shown, the second transmission component includes a limit plate 19 arranged in the slide groove 16, and the limit plate 19 divides the slide groove 16 into an upper sliding area for the second slider 18 to move and a lower installation area for installing the transmission component. A fifth bevel gear 30 is fixed at the bottom of the second screw 17 and in the installation area. A horizontally arranged rotating groove 31 is also provided on the support column of the gantry. The rotating groove 31 is connected to the installation area of the slide groove 16, and a rotating shaft 32 is rotatably installed in the rotating groove 31. One end of the rotating shaft 32 extends out of the support column of the gantry and a second rotating handle 21 is fixed thereon, and a sixth bevel gear 33 meshing with the fifth bevel gear 30 is fixed on the other end; the second rotating handle 21 is arranged at a position convenient for the operator to operate. Of course, the second rotating handle 21 here can also be replaced by other power devices, such as a motor. When the height of the L-shaped clamping plate 15 needs to be adjusted, the second rotating handle 21 is rotated to drive the rotating shaft 32 to rotate, so that the sixth bevel gear 33 fixed at the front end of the rotating shaft 32 drives the second screw 17 to rotate through the fifth bevel gear 30, so that the direction of the force is converted, which is more convenient for the staff to operate.
[0030] The specific working process of this device is as follows:
[0031] In the initial state, the two clamping arms 13 are close to the two side walls of the gantry 1. When the electromechanical equipment needs to be hoisted, the staff ties it to the electromechanical equipment to be hoisted by ropes or chains, and hangs the electromechanical equipment on the hook 8 by ropes or chains. Then the motor 4 is powered on and starts to operate. The output shaft of the motor 4 drives the reel to rotate, and drives the electromechanical equipment to rise through the sling 6. When the bottom of the electromechanical equipment rises to the set position, the two clamping arms 13 are made close to each other along the first screw 10 by rotating the first rotating handle 11, so that the two clamping arms 13 clamp the electromechanical equipment and fix it. At this time, the L-shaped clamping plate 15 is located at the lower side of the electromechanical equipment. The staff rotates the second rotating handles 21 located on both sides of the gantry 1 respectively, driving the L-shaped clamping plate 15 to slide up and down along the outer sleeve 14 through the sliding rod 141, so that the horizontal side of the L-shaped clamping plate 15 abuts against the bottom of the electromechanical equipment. At this time, the position of the L-shaped clamping plate 15 is fixed, which plays a role in supporting the electromechanical equipment.
[0032] Since the bottom sides of different electromechanical equipment may have differences in shape and height, the second rotating handles 21 provided on both sides of the gantry can make the two L-shaped clamping plates 15 abut against the bottom of the electromechanical equipment, so that the L-shaped clamping plates 15 can better protect the electromechanical equipment and are suitable for hoisting different electromechanical equipment;
[0033] After the electromechanical equipment is stably hoisted and clamped, the staff can use the roller 3 to move the hoisting mechanism together with the electromechanical equipment to the position where it needs to be installed. If the electromechanical equipment is just in the installation position, the staff only needs to install it directly. Under the clamping of the clamping arm 13, the electromechanical equipment will not shake during installation, which improves the safety of the installation process. If there is a certain deviation between the height of the electromechanical equipment and the installation position, the position of the L-shaped clamping plate 15 and the clamping arm 13 can be further fine-tuned by the motor 4. When the electromechanical equipment is adjusted to the right position, the first rotating handle 11 is controlled to make the two clamping arms 13 move away from each other to release the electromechanical equipment, and then the electromechanical equipment is installed. Since the electromechanical equipment is always protected by the clamping arm 13 and the L-shaped clamping plate 15 during transportation, the risk of shaking or falling is greatly reduced, and the safety of the staff is guaranteed.
[0034] Embodiment 2:
[0035] This embodiment is different from Embodiment 1 in that Figure 2 As shown, a fixing block 34 is provided in the middle of the sliding groove 9 of this embodiment, and the middle of the first screw rod 10 passes through the fixing block 34 and is connected to the fixing block 34 through a bearing; the setting of the fixing block 34 supports the middle of the first screw rod 10, thereby preventing the first screw rod 10 from serious deformation and making the operation more stable.
[0036] Embodiment 3:
[0037] The difference between this embodiment and embodiment 1 is that a clamping plate 35 is fixed on the opposite side of the two clamping arms 13, and a rectangular anti-skid pad 36 is fixed on the opposite side of the two clamping plates 35; the provision of the clamping plate 35 can increase the clamping area, so that the clamping arm 13 can clamp the electromechanical equipment more stably, and the anti-skid pad 25 is made of rubber. The anti-skid pad 25 will deform when it abuts against the electromechanical equipment, thereby increasing the friction force and clamping the electromechanical equipment more stably.
[0038] Embodiment 4:
[0039] The difference between this embodiment and the first embodiment is that an anti-skid pad is provided on the contact surface between the L-shaped clamping plate 15 and the electromechanical equipment; the provision of the anti-skid pad can prevent the electromechanical equipment from sliding, thereby further enhancing the protection of the electromechanical equipment.
